Description: Is a Bamboo Toothbrush Right for You? As more and more people reconsider plastic products, bamboo toothbrush isbecoming a popular alternative to the plastic kind. We produce more than 359 million metric tons of plastic every year, and a lot of it ends up in landfills. Plastic isn't designed to break down. Some plastic products like straws and toothbrushes are difficult to recycle. Bamboo toothbrushes aren't a new product, but before you make the switch, find out more about why bamboo may be an excellent alternative to reduce plastic waste at home. What is a bamboo toothbrush? Bamboo toothbrushes are manual toothbrushes, similar in design to what you would find on any store shelf. A bamboo toothbrush has a long handle and bristles to remove food debris and plaque from your teeth. The critical difference is that the long handle is made from more sustainable bamboo instead of plastic. Bamboo toothbrushes are one of the oldest types of toothbrushes. The earliest toothbrushes were made in China using bamboo and other natural materials, like using boar's hair for the bristles. Today's bamboo toothbrushes use nylon for the bristles like most toothbrushes today. Some manufacturers still use boar's hair for the bristles or infuse the bristles with activated charcoal. Are bamboo toothbrushes better for the environment? Bamboo does have a smaller ecological footprint than plastic because bamboo plants grow quickly, regrowing what was taken for the production of the toothbrush. Bamboo is also biodegradable if used in its raw form, such as for toothbrush handles. When the nylon bristles are removed, bamboo toothbrush handles can be composted, reused as garden plant markers, or other household uses! However, just like plastic toothbrush handles, they will take up space in a landfill if just thrown away. Fully biodegradable toothbrushes do exist, with natural fibers for the bristles. Keep in mind that these natural bristles tend to be rougher than nylon bristles, possibly causing wear on your enamel and contribute to receding gums. Speak to your dental hygienist about biodegradable toothbrushes or environmentally-friendly toothbrushes, and they may have recommendations. Are bamboo toothbrushes good for my teeth? Bamboo toothbrushes can be just as good for your teeth as plastic toothbrushes. When choosing any kind of toothbrush, consider the size of the head, the shape of the handle, and the bristles. Toothbrushes that can easily fit into the narrow areas of your mouth with soft bristles and a comfortable handle are the best. You should replace your toothbrush every three to four months or if there is visible damage to the bristles. Replacing your old toothbrush with a new one will help keep your teeth clean. Suppose you have more questions about switching to a bamboo toothbrush. In that case, your dental hygienist can make other recommendations that will keep your mouth healthy while considering plastic waste. BAMBOO TOOTHBRUSH BENEFITS: WHY YOU SHOULD MAKE THE SWITCH It was while I was growing up that ‘Reduce, Reuse, Recycle’ became popular. The movement toward being aware of, and protecting, our environment came of age and everyone was looking at ways to lessen our impact on the environment. These days we have evolved to a place where we’re looking for alternatives to materials that harm our environment. One of the best kids bamboo toothbrush benefits is that it is a renewable resource that is grown organically; one of the most environmentally friendly products available. Bamboo Toothbrush Benefits Bamboo toothbrush benefits encompass more than just the actual contribution to saving the environment. There is also the conscientiousness of knowing that actions you are taking will preserve plants and trees, rivers and streams, far into the future. Six Reasons To Switch To A Bamboo Toothbrush There are a number of reusable hotel bamboo toothbrush benefits to convince you to switch from what you’re using now to bamboo: Biodegradable. Bamboo is biodegradable. Unlike plastic, which can take up to 1000 (!) years to decompose, bamboo can decompose in as little as 4 months (although it will likely take 3 to 4 years). Knowing that you are using a material that will biodegrade so quickly is the number one reason to switch to a bamboo toothbrush. Renewable resource. Bamboo is one of the fastest growing plants in the world. It is an infinitely renewable resource ensuring that the supply not diminish and that we are not removing a vital plant in the eco-system from the world. Antimicrobial properties. This one is definitely a little controversial. ‘Bamboo kun’ is a natural substance within bamboo that helps the plant grow and mature quickly before harvesting. It’s not understood, however, if these antimicrobial properties continue after harvesting or after being transformed into household objects or fabric. It remains, however, an interesting point. Longevity. Lest you be concerned that a material that degrades so quickly might not be reliable; let me alleviate that. Bamboo toothbrushes last as long as, or longer, than plastic toothbrushes of the same type. Bamboo is strong, resilient, and reliable for far longer than the recommended 3 or 4 month replacement rate for toothbrushes. You may be more inclined to heed that recommendation knowing that bamboo is so biodegradable and good for the environment. Affordability. Bamboo toothbrushes aren’t any more expensive than a good quality plastic toothbrush! You can pick one up for the same couple of bucks you were going to spend anyway. Environmentally friendly. This deserves mentioning again. Not only is bamboo efficiently biodegradable, it’s also infinitely renewable, and is strong, resilient, and reliable – making it one of the most environmentally friendly materials out there. Things to Like: Recycled, biodegradable packaging Activated charcoal embedded bristles Smooth surface for a good mouthfeel These environmentally friendly, biodegradable biodegradable family bamboo toothbrush is also cruelty free and vegan friendly. You can be sure that your impact on the world is limited when using these daily. The best part about these toothbrushes is that they work as well as regular, plastic toothbrushes. The BPA free bristles clean effectively and are long lasting. They are charcoal infused; which is thought to help in preventing bacteria build up in the toothbrush between cleanings. The handle is strong and smooth for a good mouth feel. Each individually wrapped toothbrush is embossed with a number; to help each member of your family know which toothbrush is theirs. 10 Amazing Benefits of Combing Your Hair with a Wooden Comb Nature has bestowed us with many good things, and wood is one of them. Apart from being used in various ways to make our lives more comfortable, wood can also be carved into combs and used for grooming our tresses. From time immemorial, people have been using wooden combs to maintain the health and beauty of their mane. Here are some amazing benefits of using a wooden comb: 1. A Healthy Scalp A healthy scalp supports healthy locks, and one of the natural ways of taking care of your scalp is by using a wooden comb. When you use a wooden comb to brush your hair, it presses against your scalp and triggers the acupuncture points and also gives a massage to your scalp. All this proves to be good for the overall blood circulation to your scalp and proves to be of great benefit for your hair. 2. Nourishes the Hair If you are wondering how a sandalwood comb benefits your hair, well, whenever you use a wooden comb instead of a plastic comb, the natural oils present in your scalp get equally distributed across your tresses. Using a wooden comb not only reduces the chances of hair breakage and hair fall but it also helps to make your hair shinier, bouncer and healthier. 3. Promotes Hair Growth If you wish to have healthy and long tresses, then do try using a wooden comb. This is because a wooden comb improves the blood flow to your scalp, which in return helps the hair follicles get optimum nutrients. It also helps in eliminating or removing impurities by regulating the production of sebum. 4. Prevents Greasiness Most of us may be battling a greasy scalp, which results from the uneven distribution of natural oils secreted by sebaceous glands. However, when you use a wooden comb, the oil gets evenly distributed not only across your scalp but also across the length of your hair. This leaves your hair less greasy or oily in comparison to what may occur after using a plastic or PVC comb. 5. Prevents Breakage and Hair Loss Using a wooden comb may prove better for your hair than a plastic comb. This is because a wooden comb slides smoothly through the hair, leading to less breakage and damage. Also, it has wider bristles, which move easily through the hair. That reduces friction and helps in detangling the hair in a better way. 6. Prevents Dandruff Dandruff can be a very annoying scalp problem and a never-ending battle with the white scaly flakes. However, using wooden combs can help you prevent this issue because it is not only gentler and softer on your hair and scalp, but also prevents any harm to the scalp that may be caused due to friction, cuts or nicks. 7. Removes Foreign Particles and Dirt from Hair Pear wood comb is very common for our hair to attract dirt or foreign particles. However, using a wooden comb can help in getting rid of these. This is because unlike metal or plastic combs that attract such substances because of the heavy charge in them, wooden combs may easily help in clearing any such substances from your hair and scalp. 8. Prevents Allergies Plastic or metal combs may sometimes irritate or cause an allergic reaction on the skin. If you have a sensitive scalp, then using a wooden comb may be a wise thing to do. This is because these combs are made with natural components and some of these even come with a protective coating. Hence, they are less likely to irritate or cause any kind of allergic reaction on your scalp as compared to plastic combs. 9. Prevents Static Damage Static is one of the worst things that can happen to your hair because it makes your hair more prone to damage and breakage. This condition becomes more pronounced when you use metal or plastic combs. However, wooden combs prevent your tresses from getting static and thus prove to be better for your hair. 10. Adds Bounce If you are wondering what the various neem-wood comb benefits are, well, a neem comb or any wooden comb can give you bouncy tresses. When you use a wooden comb regularly, your scalp will be nourished with proper blood circulation and optimum blood circulation. Together, all this will lend a healthy bounce to your hair.

Description: Polypropylene as a Promising Plastic: A Review Darrell Griffin hates to fly, so it was with no small degree of trepidation that he faced a flight from Los Angeles to New York a couple of years ago. Desperate for a distraction, Griffin, a film producer at the time, turned to his business partner for help. "To take my mind off the flight, he put a film on my handheld PC," Griffin says. The movie was Hercules Unchained, starring Steve Reeves. The diversion worked, and by the time Griffin landed in New York, he had an idea for a new business. When they returned to L.A., Griffin and his partner sat down to figure out how they could turn that distraction into a business. "Pocket PCs are synced up all the time," Griffin says. "We wanted to figure out how to create a retail product." They devised a technology to compress filmed content from CD-ROMs into a format PDAs could display. Then in November 2001, Griffin helped launch Pocket PC Films, in Sherman Oaks, Calif., to distribute video content for Pocket PC and Palm OS devices. Film fans can buy CD-ROM titles, load them on their computer and sync them into their handheld device. (The films will also run on desktop PCs, but the format remains handheld-size due to licensing issues.) Griffin, now president of Pocket PC Films, has high hopes. "The market is growing faster than we thought," he says. "Dataquest estimates that 23 million PDAs will be shipped in 2003, but that was before Dell and ViewSonic announced plans to offer models." Beware the 9 warning signs of bad IT architecture and see why these 10 old-school IT principles still rule. Pocket PC Film now distributes 25,000 titles, priced from $9.99 to $49.99, that run the gamut from 1941’s King of the Zombies to Oliver Stone’s more recent Natural Born Killers. The company also provides self-help and business-oriented content, as well as classic TV packs with shows like Dragnet and the Sports Illustrated’s "Swimsuit 2002" special?the most popular title so far. High Impact Polystyrene (HIPS), which made of HIPS rigid film, and Rigid Vinyl (sometimes referred to as PVC or RPVC) are often the main films considered for a variety of lower cost applications such as point-of-purchase signage, shelf danglers, membership and loyalty cards, and tags to name a few. On the surface, it is sometimes viewed that the two films are often interchangeable and either one can be used. However, there are some key differences in film characteristics that leads to one film being the better choice over the other depending on the application needs. The chart below compares key characteristics of the two films and will help you make the best choice in using either rigid vinyl or polystyrene film Plastics are categorized into four main groups: thermoplastics, elastomers, thermosets and polymer compounds. Macromolecular structures distinguish the class of any plastic material as well as its physical properties. Elastomers and thermosets have soft and hard elasticity, respectively; and their resins cannot be melted for recycling purposes. However, thermoplastics are either amorphous or semi-crystalline. Amorphous resins are disordered statistical oriented macromolecules whereas semi-crystalline resins macromolecules are nearly ordered since they are embedded with crystalline phases. Typical amorphous resins are polycarbonate (PC), polystyrene (PS) and polyvinylchloride (PVC) where typical semi-crystalline resins includes polyamide (PA) and polypropylene (PP). Since PP is under the semi-crystalline class, our focus will be on this group. The annual global demand for plastics reached 245 million tons and it is project to grow dramatically because of the increase in public demand. Figure 2 shows the total plastics demand by 2006. Around 90% of the total demand is accounted for five main commodity plastics: polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS) and polyethylene terephthalate (PET). In 1954, Giulio Natta discovered PP, but commercial production began in 1957. PP is the most widely used thermoplastic since it is very cheap and flexible for molding. The second common plastic type is PE. There are different grades of PE linear low density (LLDPE), low density (LDPE), medium density (MDPE) and high density (HDPE). The density of PE grades ranges between 0.925-0.965 and obviously is higher than PP. However, the uniqueness of PVC film is associated with chlorine content (57 wt. %) in its structure. Annual worldwide PVC demand is approximately 35 million tons. According to previous studies, plastics are the most recyclable materials and there were 4.4 million tons of plastics recycled in 2006.Polypropylene chemical resistance can be described as follows: excellent resistance to dilute and concentrated acids, alcohols and bases, good resistance to aldehydes, esters, aliphatic hydrocarbons, ketones and limited resistance to aromatic and halogenated hydrocarbons and oxidizing agents. Polypropylene has a crystalline structure with a high level of stiffness and a high melting point compared to other commercial thermoplastics. The Hardness resulted from the methyl groups in its molecular chain structure. Polypropylene is a lightweight polymer with a density of 0.90 g/cm3 that makes it suitable in many industrial applications. Still, polypropylene is not suitable to be used at temperatures below 0°C. Experiments proved that polypropylene has excellent and desirable physical, mechanical, and thermal properties when used in room temperature applications. It is relatively stiff and has a high melting point, low density and relatively good resistance to impacts. Typical crystallinity of PP is between 40-60%. PP is a low-cost thermoplastic polymer with excellent properties like flame resistance, transparency, high heat distortion temperature, dimensional stability and recyclability making it ideal for a wide range of applications.Propylene is one of the most important industrial petrochemical building blocks used to produce various chemical derivatives. The dominant outlet for propylene is PP which accounts for nearly two-thirds of global propylene consumption as shown in Figure 3. There are three major sources of propylene: from steam cracking of naphtha, gasoline refining process and propane dehydrogenation technology. Polypropylene is the most important material among polyolefins due to three main reasons. First, great properties of PP such as low density, high melting temperature and chemical inertness with low cost making PP optimum for long-life applications. Second, polypropylene is a highly versatile material meaning that diversity in structural designs and mechanical properties are achievable. Third, different morphological structures of PP are possible by using fillers or reinforcing agents and blending PP with other polymers which yield to have superior characteristics. Special and reinforced polypropylene grades include elastomer-modified PP, elastomer modified filled PP, glass fiber-reinforced PP, filled PP, esthetic filled PP, flame-retardant PP and thermoplastic elastomers. A study shows that branching process of linear Ziegler–Natta polypropylenes is possible by creating chains based on the molecular weight distribution. Introducing branching into a linear polypropylene will result in having a product with high molecular weight, high melt strength and better properties like high modulus and tensile strength, rigidity and excellent heat resistance. Branching parameters β, the average number of branch points per molecule, and λ, the number of branch points per 103 carbons, are calculated to identify the polymer structure and properties. A post-reactor is used for the branching process. The branching efficiency is associated with chemical composition and temperature of the reaction. The relationship between branching parameters and molecular weight is important to design polymers with unique properties for different applications. PP rigid film is very suitable for reinforcing and filling. Thus, another study focuses on studying the effect of fibers reinforcement on the mechanical properties of fiber-reinforced polypropylene composites (FRPCs). A composite material is a polymer matrix that is embedded with reinforcement fibers such as glass or carbon. FRPCs have better durability, moisture resistance and high strength properties; making them ideal in applications related to constructions, sports equipment and cars. Synthetic fibers yield to have better mechanical properties compared to natural ones. Glass fibers are widely used as a synthetic reinforcement with PP to produce very good mechanical properties composites. However, mechanical characteristics of composites are controlled by numerous fiber treatments and coupling agents. Fiber diameter is another significant factor in designing composites material. A certain value of fiber diameter thickness should not be exceeded; if so fibers will decrease composites strength. Electrically conductive PP and PE composites are cost-effective, commercially proven and with outstanding electrical and mechanical properties. It is mandatory to understand the distribution, orientation, interaction and aspect ratio of conductive fillers with the polymer matrix to obtain the required conductivity. Better filler-matrix interactions are achievable at low viscosity, low surface tension and high crystallinity. Grafting technique initiates the interactions and the distribution of the fillers with PP and PE matrices.

Description: Types of Hourglass Before the invention of mechanical clocks, timepieces used the sun's motion or simple measurement devices to track time. The sundial may be the best known ancient keeper of time, and it is still manufactured as a popular garden accessory—but for its visual interest, not for practical time measurement. Stonehenge, the giant monument built of upright stones on the Salisbury Plain of Wiltshire, England, may have been used as a sundial and for other time and calendar purposes. Sundials have obvious disadvantages; they can't be used indoors, at night, or on cloudy days. Other simple measurement devices were used to mark the duration of time. Four basic types could be used indoors and regardless of the weather or time of day. The candle clock is a candle with lines drawn around it to mark units of time, usually hours. By observing how much of the length of a candle burned in one hour, a candle made of the same material was marked with lines showing one-hour intervals. An eight-hour candle showed that four hours had passed when it had burned down beyond four marks. The clock candle had the disadvantages that any changes in the wick or wax would alter burning properties, and it was highly subject to drafts. The Chinese also used a kind of candle clock with threads used to mark the time intervals. As the candle burned, the threads with metal balls on their ends fell so those in the room could hear the passage of the hours as the balls pinged on the tray holding the candle. The oil lamp clock that was used through the eighteenth century was a variation and improvement on the candle clock. The oil lamp clock had divisions marked on a metal mount that encircled the glass reservoir containing the oil. As the level of oil fell in the reservoir, the passage of time was read from the markings on the mount. Like the candle clock, the oil lamp clock also provided light, but it was less prone to inaccuracies in materials or those caused by drafty rooms. Water clocks were also used to mark the passage of time by allowing water to drip from one container into another. The marks of the sun's motion were made on the first container, and, as water dripped out of it and into another basin, the drop in water level showed the passage of the hours. The second container was not always used to collect and recycle the water; some water clocks simply allowed the water to drip on the ground. When the eight-hour water clock was empty, eight hours had passed. The water clock is also known as the clepsydra. History Sand timer hourglass (also called sand glasses and sand clocks) may have been used by the ancient Greeks and Romans, but history can only document the fact that both cultures had the technology to make the glass. The first claims to sand glasses are credited to the Greeks in the third century B.C. History also suggests sand clocks were used in the Senate of ancient Rome to time speeches, and the hourglasses got smaller and smaller, possibly as an indication of the quality of the political speeches. The hourglass first appeared in Europe in the eighth century, and may have been made by Luitprand, a monk at the cathedral in Chartres, France. By the early fourteenth century, the sand glass was used commonly in Italy. It appears to have been widely used throughout Western Europe from that time through 1500. The hourglass or sand clock follows exactly the same principle as the clepsydra. Two globes (also called phials or ampules) of glass are connected by a narrow throat so that sand (with relatively uniform grain size) flows from the upper globe to the lower. Hourglasses were made in different sizes based on pre-tested measurements of sand flow in different sizes of globes. A housing or frame that enclosed the globes could be fitted to the two globes to form a top and bottom for the metal sand timer and was used to invert the hourglass and start the flow of sand again. Some hourglasses or sets of hourglasses were set in a pivoted mount so they could be turned easily. The earliest writings referring to sand glasses are from 1345 when Thomas de Stetsham, a clerk on a ship called La George in the service of King Edward III (1312-1377) of England, ordered 16 hourglasses. In 1380, following the death of King Charles V (1337-1380) of France, an inventory of his possessions included a "large sea clock … in a large wooden brass-bound case." John Harrison and his brother James were introduced to clock repair by their father, Henry. At the time, clock making, or horology, was undergoing a developmental revolution. Mechanical clocks had existed since the fourteenth century, but had remained rather primitive in their operation until Christiaan Huygens invented the weight-and-pendulum clock in 1656. One limitation was that they were totally dependent upon the earth's gravity for their operation. This meant that they could not keep accurate time at sea, and could not be adapted for portability. Even moving them across a room would require adjustment. The Harrison brothers set to work on developing a marine chronometer in 1728. The motivating factor was money. In 1714, the English Admiralty set up an award of ￡20,000 for anyone who could provide mariners with a reliable clock that, when used with celestial sightings, could keep them informed of their longitude at sea. Mariners had to rely heavily on dead reckoning to find their way, often leading to tragic results. The Harrison strategy was to design an instrument that was not only internally accurate but also externally stable. The Harrisons made several models of marine chronometers. The fourth model proved to be the most successful. On a nine-week voyage from England to Jamaica in 1761, the device had only a five-second error. The Board of Longitude, apparently miffed that a common artisan had achieved the coveted goal, reluctantly gave up only half of the prize. John, minus his brother, refused to accept only half of the reward and persisted until the other half was relinquished. The Board subjected his invention to undue scrutiny and required him to design a fifth model. This time, Harrison outdid himself by designing a compact timepiece that resembled a modern day pocket watch. It was far more convenient than the previous models, which were heavy and bulky. The Board still refused to capitulate. Finally, only a personal appeal to King George III and the King's intervention could set things right, and Harrison received the full reward in 1773 at age seventy-nine. Harrison lived only three more years. These two early associations of sand clocks with the sea show how navigation had become a time-dependent science. Compasses and charts, developed in the eleventh and twelfth centuries, helped navigators determine bearings and direction, but time measurement was essential to estimating distance traveled. The sand glass may have been invented —or perfected—for use at sea where equal units of time were measured to estimate distance; by contrast, on land, unequal time measurements were more important because activities depended on the length of day. The great advances in maritime science occurred in the twelfth century with the development of the magnetic compass in Amalfi, Italy. Other Italian port cities like Genoa and Venice contributed to the astronomical advances in navigation, and, by coincidence, Venice was the world's greatest glass-blowing center. Furthermore, the fine marble dust from the quarries at Carrara was perfect for use as sand in navigational sand clocks. As well as measuring time as distance at sea, hourglasses were used by the navies of several nations to "keep the watch" or measure the time the crew worked. The ship's boy was in charge of turning the hourglass; to get off work early, he would "swallow the sand" or turn the glass before it was empty. The most extraordinary hourglasses were made as gifts for royalty. Charlemagne (742-814) of France possessed a 12-hour hourglass. In the sixteenth century, Holbein (1497-1543) the artist made spectacular hourglasses for Henry VIII (1491-1547) of England. Other sand glasses contained multiple instruments. For example, a sand glass made in Italy in the seventeenth century contained four glasses. One had one-quarter hour of sand; the second, a half-hour of sand; the third, three-quarters of an hour of sand; and the fourth contained the full hour's measure of sand. Some glasses also had dials with pointers, so, with each turning of the glass, the number of turns could be shown with the pointer to mark the cumulative passage of time. The upper and lower globes of each glass were blown separately with open apertures or throats. To join them so that sand could flow from the upper globe to the lower, the two halves of the glass were bound together with cord that was then coated with wax. The two-coned glass phial could not be blown as one piece until about 1800. In about 1500, the first clocks began to appear with the invention of the coiled spring or mainspring. Some weight-powered clocks had been made before 1500, but their size limited their practicality. As the mainspring was improved, smaller, tabletop clocks were manufactured and the first watches were made. Mainspring-driven clocks made curiosities out of clepsydras and sand glasses, but, interestingly, the most beautiful hourglasses were made after 1500 as decorative pieces. There are many types of hourglasses, such as metal hourglass，wood hourglass and so on. By the 1400s, many private homes had sand clocks for household and kitchen use. Sermonglasses were used in churches to track the length of the minister's sermon. Hourglasses were also routinely used in the lecture halls of Oxford University, craftsmen's shops (to regulate working hours), and in England's House of Commons where bells to signal voting and lengths of speeches were timed based on sand clocks. During the height of the sand glass, doctors, apothecaries, and other medical practitioners carried miniature or pocket sand glasses with durations of one-half or one minute to use when timing pulses; the practice of carrying these continued until the nineteenth century. Today, miniature versions containing three minutes worth of sand are sold as egg timers and as travel souvenirs. Larger sand clocks are still made today of ornamental materials and in interesting styles for use as decoration. All of these measuring devices (clock candles, water clocks, and sand clocks) have the disadvantage that they must be watched carefully. How to use a massage ball Like a foam roller, a massage ball can also be used to help release tension in our achy muscles after long hours spent in the office or after a workout. One of the differences being that it can get to those hard to reach areas such as the upper back, buttocks and feet. “Knots” or “trigger points” can be massive sources of pain in our bodies and using self-massage techniques can be very satisfying. Before diving in, there are a few important things to know which will help you achieve the best results. Why a massage ball Massage balls are affordable and small and therefore they can easily fit into a suitcase or handbag to use wherever you go. They also promote self-sufficiency so there is no need to rely on anyone else. Notwithstanding, it does not always give the same results as a traditional massage delivered by an experienced therapist Find the right ball There are many different types of massage balls ranging from very smooth and firm like a lacrosse ball to small and soft like a squash ball. Other balls include a tennis ball and the trusty spikey massage ball. To each his own but if you’re new to using a massage ball, perhaps start with a spikey ball or a tennis ball. Where and when Since they are so conveniently easy to use, you can use them almost anywhere for example against a wall, the back of a chair, on the floor or use your hands. Some office workers keep them at their desks as a reminder to use them during the day to help with releasing built-up muscle tension from poor posture or stress. Start with only a few knots at a time, the most painful area being first. The idea is to trap the knot in the muscle with the ball and apply gently to medium pressure until the painful sensation has faded. Once you have the correct spot (and you will know when), hold it there and try to relax until only about 80% of the ache remains. When pressing too firmly, the sensation can be too painful for you to relax which defeats the purpose of using the massage ball in the first place, it could also potentially irritate the area. You are looking for a “good pain”.Roll the ball around to look for more tender spots or just enjoy gently going back and forth over the tight muscle. If you feel the muscle needs it, you can repeat it twice a day. After releasing the knot, follow it up with gentle stretches to the same muscle. It’s okay to lightly exercise the muscle afterward but avoid fatiguing it for 24 hours. The gear shift knob in a manual transmission equipped car or light truck is the large knob, usually made of plastic, that attaches to the top of the gear shift lever. Over time the surface of the knob can wear and you might wish to replace it to spruce up the interior of your vehicle. Many aftermarket manufactures offer specialty gear shift knobs. Some of these are made out of exotic materials such as leather or billet aluminum. Some companies offer novelty gear shift knobs for owners who want to personalize the interiors of their vehicles.

Description: WHAT IS CORRUGATED CARDBOARD AND WHY IS IT ESSENTIAL FOR SHIPPING GOODS? Did you know that approximately 95% of all products in North America are shipped in corrugated cardboard containers? In fact, corrugated boxes are such an essential part of our supply chain, that packaging manufacturers were able to continue operations through the COVID shutdowns as essential business entities. Corrugated cardboard is very durable by design and consists of multiple layers: an outside liner, an inside liner, and a fluted layer between the two. The three layers are glued together to create corrugated cardboard. Also referred to as corrugated fiberboard, the material offers significant advantages over other options when it comes to shipping. The Advantages of Corrugated Cartons for Shipping Plain and simple, corrugated cardboard boxes provide the right level of protection for goods in transit. Shipping cartons can go through a lot from the warehouse to their final destination. Corrugated packages are designed to survive bad weather, bumpy roads, sudden temperature changes, or rough handling–all while keeping products safely intact. While no corrugated package is completely indestructible, the materials and makeup of these containers are more likely to protect your products in transit. Your customers are more likely to be happy when products arrive in top condition. If customers receive a damaged or broken item, they will be unhappy. And we all know that unhappy customers are less likely to make a repeat purchase. Even though corrugated cardboard packaging is very sturdy, it is also lightweight. This can help keep shipping costs down. Corrugated boxes can be fashioned into a variety of shapes, allowing your company more control over the kind of unboxing experience your consumers will have when your products arrive. This is especially important for e-commerce businesses that ship consumer goods. And finally, corrugated cardboard boxes are constructed of renewably-sourced materials. Since they are made mostly from trees, a renewable resource, this kind of packaging is very easy to recycle. When recycled properly, corrugated cardboard packaging is processed into paper products and even new boxes. What’s also great about corrugated cardboard is its multi-use properties. Thanks to the material’s durability, many corrugated packages can be reused multiple times before they even hit the recycle bin. The sustainability of corrugated cardboard is also what makes this material very affordable. How Cosmetics Boxes Help Your Brand Every woman wants to look attractive and beautiful. For this purpose, a variety of cosmetic products are used. Cosmetics, itself is a symbol of beauty. Therefore its packaging should be such that which complements the product. Every day, a number of cosmetic brands are introduced in the market offering a wide range of cosmetic products at more competitive prices. It becomes extremely difficult for the customers to choose among a number of alternates. Packaging plays an important role in this regard. The brands which succeed in creating perfectly designed cosmetics boxes for their product range wins the race. As the packaging box is the first thing with which customers get interacted. So the custom printed boxes should be attractive enough to grasp the attention of the customers at first sight. Moreover, your display packaging plays an imperative role in promoting your brand and making it recognizable for the customers. Below are some of the ways how cosmetics boxes help your brand: Protect The Products Using cosmetics boxes for your product range is the best way to protect your products from any damage. When a product is shipped, the chance of damage increases due to various reasons like mishandling, carelessness, stacking or the vehicle may get accident etc. Using perfume boxes for your products reduces the risk of potential hazards. They keep the delicate items safe during transportation, storage, shipment or when placed on retail shelves. Cosmetic are the things which every woman prefer to try before purchase. Cosmetics boxes at TheCustomboxes provide the products from accidental damage, fall or mishandling by the users. They are designed from highly durable cardboard material. It acts as moisture resistant and saves the content from humidity, sunlight or changes in temperature. This increases the useful life of the product. Only if a company ensures safe delivery of its products to the customers, he is able to compete in the market. Speed Up Decision Making Process Designing the cosmetic display packaging in an attractive manner is a great way to speed up the decision making process. Heavily promoting the product on media is not only the way to boost up the sales. Rather packaging is a thing which creates a great difference. Well designed custom printed boxes create a positive impact on the minds of the customers thus stimulating their purchase behavior. As it’s a matter of just a few seconds, so customers do not have time to evaluate the pros and cons of a product when they shop. Therefore, cosmetic packaging should be such that it puts a valuable first impression on the customers and speeds up the decision making process. Attracts The Customers Shoppers are influenced by the cosmetics boxes which look attractive and different from others. Customers always prefer something innovative. A packaging which creates a great shelf impact has the ability to attract a heap of customers. Color plays an important role in this aspect. Different colors create a different psychological impact on the minds of the customers. Therefore, before finalizing a color for your brand, make an analysis that who are your target customers and which influence them the most. Customers never give a second chance to the cosmetic packaging which looks unattractive. So it’s one time chance to win the race. Many of the brands have changed their cosmetic packaging to attractive gift boxes to fascinate the customers. It’s a useful tactic which proves highly significant. What is the Future of Food Box On Monday, March 22, the USDA held a 12-hour listening session to hear feedback from the public about the Farmers to Families Food Box Program. The program was created almost a year ago at the peak of the pandemic lockdown. It was designed to quickly move surplus commodities from farmers to consumers in need and hopefully support some idled workers and distribution systems in the process. The goals were broad, and the rules were loose. There were many criticisms that the rules were too loose and the cost was too high, and about four months in, the USDA put more structure into place around the program. At that point, the program seemed to shift the balance more toward providing food for people in need rather than supporting farmers or the supply chain. The USDA was providing direct payments to farmers and the media had stopped reporting on crops being plowed under and milk being dumped. Yet, there was plenty of footage of cars lined up for miles to receive the food box. That shift to helping consumers, and the earlier criticisms, led the USDA to focus more on cost per box in the later rounds of the program. The Truth About Paper Bags These days, when you hear the question, “Paper or plastic?” the answer is an almost instinctive “Paper!” We all know that plastic is terrible for the environment, and that plastic bags, in particular, are clogging up our oceans, choking our wildlife and generally wreaking havoc on the world. Because of this, and because the paper bag industry has positioned itself as the solution for decades now, we rarely stop to ask a critical question: Is paper actually that much better? The truth is, no, it’s not. Paper does a lot of damage to the Earth as well, and every time we unthinkingly grab a few bags at the checkout stand, we contribute to that damage. It’s time to learn the truth about paper bag, so we can start making better choices today. Because the answer to “Paper or plastic?” should actually be “Neither … I brought my own.” Not That Much Better Than Plastic Paper bags just seem friendlier to the environment, right? They don’t have that slick petroleum look like plastic bags do; they’re a cheerful kraft color; they fold up neatly to stack in your cupboard for next time (assuming they didn’t get destroyed this time). But research, such as this report, makes clear that plastic really doesn’t have much on plastic. To wit: It doesn’t break down any faster than plastic in landfills. That’s because, while paper breaks down much faster under ideal conditions, landfills are not ideal conditions. The lack of light, air and oxygen means pretty much nothing decomposes, so paper and plastic are destined to spend equal amounts of time there. Gift paper bags are bigger than plastic, which means they take up more space in landfills. They’re recycled at a higher rate, which mitigates that fact, but that still means they still have a greater per-bag impact on landfills. It takes four times as much energy to manufacture a paper bag, as compared to plastic, and the raw materials have to come from trees, a natural resource that is otherwise carbon-fixing. Making paper bags not only adds waste to the world, it kills one of our greatest tools for fighting pollution. Paper bags generate 70 more air pollutants than plastic. They generate 50 times more water pollutants than plastic. It takes 91 percent less energy to recycle a plastic bag than it does a paper bag. Shopping paper bags are very thick, so shipping them costs more fuel per bag. This report is admittedly biased toward plastic (and reusable bags), but if this is starting to sound like a vote for plastic bags, think again. Plastic leaches chemicals into our oceans and waterways, breaks into small pieces and accumulates in the stomachs of baby birds, strangles fish and collects into great seafaring clumps that become islands and continent-sized garbage patches. The point isn’t that plastic is good; it’s that our unwavering assumption that paper’s okay is wrong. Here are a few more reasons not to trust that paper bag’s cheerful, eco-friendly-looking fa?ade.

Description: HOW TO CHOOSE THE RIGHT LED SHOEBOX LIGHTS FOR YOUR PARKING LOT If you are considering upgrading your lights to LED, the parking lot lights should always be the first one to take into consideration, because of the large service area of parking lot and the high energy consumption of traditional metal halide parking lot light. It’s not easy to research dozens of websites to put all the pieces of the puzzle together and answer all of your questions about what is the right LED shoe box light Fixture for your needs. For this reason, we prepared some tips about shoebox light, Parking Lot and Area Lighting in this article. Here are several things you need to know before converting your facility: 1. Type of facility: Is the site retail, warehouse or other commercial use? 2. Type of fixture or lamp: Wall Packs, Shoeboxes, Flood Lamp 3. Wattage of existing lamps: This gives your LED manufacture insight to the LED equivalent needed. 4. Line voltage: LED products are voltage specific, and the LED installer will need to know this detail. 5. Needs from the changes: To increase/decrease the lighting output, address a specific problem or area, meet a specific specification or code 6. The best color of light: The sun is 5778k, and in the LED industry, 5000k is considered to be the closest to natural sunlight. Outdoor lighting is often oriented to a 5000k color. 7. Quality of LED products: Quality means you trust you will not have any warranty issues, service means if you do have any issues, the integrity of service will be tasked to work its magic. What is high bay lighting, and what applications benefit from it? Whenever a large indoor space needs to be illuminated, high bay lighting is usually appropriate. Consider spaces like manufacturing facilities, gymnasiums, warehouses, large department stores, factories, and more; these facilities are typically vast and cover a lot of vertical as well as horizontal space. This requires powerful lighting to provide the appropriate foot-candle levels to adequately illuminate. High bay lighting fixtures typically hang from the ceiling via hooks, chains, or pendants, or they may be fixed to the ceiling directly (similar to troffer lights). The image above features high bay lighting in action. Various industries and facilities require high bay lighting. Some of the most common are: Warehouses Industrial facilities (read more about Industrial LED lighting here) Manufacturing facilities School and university gymnasiums Municipal facilities like community centers or recreation centers Commercial applications like department stores Why choose LED high bay lights instead of metal halide, fluorescent, or other conventional high bay lights? Historically, various lighting technologies were (and still are) used in warehouse and industrial settings when high bay lights were required. Some of the most common include metal halide (MH), high pressure sodium (HPS), and fluorescent. While each of these bulbs have their merits, industrial LED lighting outperforms its conventional counterparts in important ways. Let’s take a look at some of the various considerations when deciding whether an LED retrofit is appropriate for your warehouse or industrial space. Industrial LED lighting vs metal halide high bay light: If you’ve ever been to a ballgame, you've likely seen metal halide illuminating the field. MH lamps are common in sporting and warehouse/industrial uses (as well as any setting where large, high spaces need to be illuminated). Benefits of MH lights include decent color rendering and comparatively adequate foot-candle levels (as opposed to other types of conventional bulbs). Some of their major drawbacks are a long time to warm up (sometimes 15-30 minutes) and a high cost to maintain, and their failure characteristics include flickering on and off. This is in addition to the fact that much of the energy they produce is wasted as heat. Read more about LED versus Metal Halide Lights. Linear LED high bay light vs high pressure sodium (HPS) lights: HPS lights are often used in warehouse, industrial, business, and recreational facilities where high bay lighting is appropriate. Their benefits include cheap selling price, high energy efficiency (low operating costs), and a relatively long lifespan. HPS lighting technology retains these advantages over most conventional bulbs, but they lose on all three counts to LED high bay lighting. The downsides of HPS bulbs include the worst color rendering on the market and a warm up period. Read more about LED versus High Pressure and Low Pressure Sodium Lights. Industrial LED lighting vs fluorescent lighting: Though somewhat less common, fluorescent lighting is sometimes utilized in warehouse or industrial applications (primarily T12, T8, and T5 lights). The benefits of fluorescent lights include cheaper initial costs and relatively high efficiency (especially when compared to other conventional bulbs). Downsides include the presence of toxic mercury (which requires certain waste disposal procedures), decreased lifetime if switched on and off, and requiring a ballast to stabilize the light. Read more about LED versus Fluorescent Lighting. It’s no secret that LED lighting technology has surpassed the capabilities of conventional lighting in important ways. In addition to the considerations discussed above, there are three general benefits of LED lighting that apply to all lighting applications. Decreased maintenance requirements. As discussed above, LED lights have a lifespan that is four to forty times longer than many conventional bulbs. This means fewer replacements for bulbs that wear out. LED lighting technology also generates light differently than typical fuel and filament lighting by using a diode (learn more in this blog). This means that there are fewer moving pieces to break, and consequently, fewer repairs or replacements. Maintenance is an especially important consideration when it comes to industrial lighting or warehouse lighting. By definition, high bay lights have higher mounting heights, which means that changing a bulb requires some specialized equipment or creativity. Scaffolding, catwalks, and hydraulic lifts are generally used to swap or replace bulbs, and each of these can result in additional maintenance or equipment costs. Again, the lifespan of industrial LED lighting means that fixtures need to be changed much less often, which means savings for your bottom line. Improved lighting quality. Industrial LED lighting and high bay lights will typically score better in a head-to-head comparisons against most other bulbs when it comes to color rendering index (CRI), correlated color temperature (CCT), and foot candles. CRI is a measurement of a light’s ability to reveal the actual color of objects as compared to an ideal light source (natural light). In non-technical terms, CCT generally describes the “glow” given off by a bulb - is it warm (reddish), or cold (bluish white)? Foot candles compare the amount of light coming from a source and the amount of light hitting the desired surface; they’re basically a measure of efficiency. On all three fronts, LED lights perform very well. (Read more about CRI, CCT, and foot candles here.) Increased energy efficiency. Not only do LED lights generate light differently, they also distribute light differently than conventional lighting solutions, which results in less energy required to provide the same output. How does that work? First, many conventional lights waste a lot of the energy they produce by emitting it as heat (this is especially the case with metal halide lighting). Second, most conventional lights are omnidirectional, which means that they output light in 360 degrees. So, a lot of light is wasted pointing at a ceiling, or being diluted because it has to be redirected through the use of fixtures. Industrial LED lighting for applications that require high bay lights eliminates these two problems of wasted energy (through heat loss and omnidirectional emission). Indoor Plant Lighting Indoor plant lighting gives plants most of the energy they need to grow, thrive, even to stay alive. The proper type of indoor plant light is more than just a matter of giving a plant the brightness it needs. There are three lighting factors that control growth of a plant: Amount of light: number of hours of daylight on your plants Intensity of light: levels of light from full sun to full shade Spectrum: warm and cool colors Gas Station Lights Every location has its own unique lighting needs. When it comes to gas station lights, there are a few fixtures that are exceptionally well suited to this location. Let's take a look at a few of the most common solutions for gas station lighting. LED When looking at fixture options, you should first determine the right lamping solution to narrow down the choices. LED is the best choice for this unique location. LED offers a higher lumen output for a brighter fixture while operating on a lower wattage which saves on energy for utility costs. LED is also a no heat solution which means the life of the fixture will be protected from heat damage. Another benefit of LED is that the lamps last a long time to save on replacement costs and maintenance spent on maintaining fixtures. Best of all, LED is available in the most commonly used gas station lighting solutions. Canopy Lights When looking at gas station lighting, the most obvious area is the canopy. This is where the majority of the business happens since customers pump gas under the canopy. It is also important to make sure this area is well-lit, so customers can see it clearly from the road at night. A well-lit canopy also gives a feeling of safety and security when pumping gas at night that most customers expect. In fact, most customer will pass up a poorly lit gas canopy in favor of a brighter one, so this area directly impacts your business. This is where canopy lights come in and save the day! Canopy lights are made specifically for this type of environment, so they offer such features as vandal proof options, wet rated listings, durable polycarbonate lenses, and bright, powerful illumination where you need it most. Canopy lights come in choices of thin profile to save on space and low profile for lower canopies in terms of height. Parking Lot Lights While the canopy lights are the main draw on the exterior, you will still need additional parking lot lighting. Parking lot lighting is necessary for any surrounding parking spaces not covered by the canopy. They can also be used to add visibility to roads leading to the parking lot or behind the building for added safety and security. When choosing parking lot lights, you can go with either cobra head or floodlights. Floodlights are ideal if you have a larger lot whereas cobra head is ideal for smaller lots. Interior Lights While the outside lighting is important, the inside is just as crucial to a successful lighting plan. For interior gas station lighting, there are several great options to consider. A few of the most common are recessed troffer-style and surface mounted fixtures. Both options offer an easy to install and maintain solution to meet the needs of this location. In this type of location, you want to avoid suspended or chain fixtures since they can create more shadows and detract from the clean, bright atmosphere your customers appreciate.
