A Reflector refers distinctly to an equipment used by photographers and cinematographers to bounce light in a certain direction. It acts as a medium to bounce light and redirect light to illuminate the subject more effectively! A reflector can be either artificial or natural, natural reflectors are objects in the environment that naturally reflect light - cars, walls, buildings, roads and other reflective surfaces are natural reflectors. Artificial reflectors are used by photographers to control the brightness and intensity of available light and to counteract harsh over exposure due to available light. The artificial reflector is made up of two parts, the reflective material and the frame. The purpose of the frame is to keep the reflective material taught at an angle that directs the reflected light to a specific direction.  There are many different reflective surfaces used, the most common being, white, silver and gold. Depending on the specific reflective material used, a different

 Orthopedic shoes, also known as custom-made therapeutic shoes, are designed for patients with significant deformities. They are made to fit specifically to their morphology. This equipment aims to improve the functions of walking, particularly thanks to the orthopedic insoles called plantar orthoses. Orthopedic shoes feature orthotic insoles that provide good arch support. The main purpose of the arch support is to eliminate excessive pronation, which affects foot function and is the main cause of foot and heel pain. Orthotic insoles help reduce pressure on the heel and the ball of the foot by transferring a substantial portion of body weight to the arch. In shoes without good arch support, the arch area doesn’t participate in distributing the pressure under the foot. Excessive pronation causes the leg to internally rotate, putting stress on the knee, hip and lower back. Orthotic insoles with good arch support play an important role in alleviating stress on the knees, hips and lower b

Even for major catastrophes like losing a head, cockroaches don’t bleed very much. Unlike humans, they have an open circulatory system: A system for distributing blood through their bodies that doesn’t depend on a closed network of arteries and veins. Their blood doesn’t pump under pressure like ours, but just sort of sloshes around, making its way into the cockroach’s tissues. The great thing about this system, if you’re someday going to be headless is that when a major wound occurs, blood doesn’t suddenly get forced out. For a cockroach that loses its head, the blood just clots at the neck. The cockroach will have a nasty scab for sure (where its head used to be), but it won’t die from loss of blood. Unlike humans, cockroaches don’t breath through a nose or their mouth. Instead they breathe through small holes in their bodies called spiracles that don’t need a brain to direct them. No nose, no mouth, and no need for a brain to regulate your breathing means that you can breathe all yo

The two most commonly recognized smoke detection technologies are ionization smoke detection and photoelectric smoke detection. Ionization smoke alarms are generally more responsive to flaming fires. How they work: Ionization-type smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.  Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”). How they work: Photoelectric-type alarms aim a light source into a sensing chamber at an angle away from the sensor. Smoke enters the chamber, reflecting light onto the light sensor; triggering the alarm. For best protection, it is recommended both (ionization and photoelectric) technologies be used in homes. In addition to individual ioni

Venom and Poison are both toxic substances. Still, some animals are called venomous and others are poisonous. The only difference between being called poisonous or venomous is in the way these animals deliver the harmful substance. Venom: When animals like snakes use their sharp fangs to bite into the flesh and let the toxic substance move into the body of their prey,  through the punctured skin, they are called venomous animals. To deliver venom an animal has to use tools like fangs or stingers. Poison: Poison is something that can get inhaled, ingested or seeped into the skin directly. For example, if you accidentally touch a brightly colored poison dart frog, you will transfer the toxins it secretes from its skin, to your own skin. And then the poison will seep into your blood stream.

 The trucks carrying explosives have a metal chain touching the ground ,True. This is all because of the charges produced by the friction which is generated by the tires moving. When the tires move they create certain amount of charges which are enough to blow up the explosive tank. The main motive is to do earthing so that the charges flow down in the earth and prevent the truck from getting blown up or you can also say preventing the explosives to blast.

  After you have crossed the 1,200km mark on the odometer, then you can rev upto 3,000-3,200rpm and maybe touch 100-110 kmph. For car with diesel engines, you need to keep your revs even lower for the first 1,000km, say till 2,000 rpm. After that you can rev your car till 2,800rpm for the next 500-700km. Avoid accelerating too quickly and braking too hard, till the time it is possible. In case of a real emergency, you of course can do either. Try and shift gears as smoothly as possible, in the recommended rev band. We also suggest that you do not undertake long distance trips before you have run-in your car. Ideally we would ask you to avoid getting stuck in traffic too but given the scenario in India, it is too long a shot. Even then, we suggest you be as gentle as possible with your car. Most manufacturers also suggest that you change the oil of your vehicle after 1,000-1,200 km as metal shavings might find their way in the oil reservoir. So then there are chances of engine damage to

The bumps or nipples found on the F and J keys on the keyboard helps users correctly position their left and right hand on the keyboard without having to look at the keyboard. For example, without looking at your keyboard you should be able to feel the keyboard and correctly position your left index finger on the F and the right index finger on the J. From this position, you should be able to locate the remainder of the keys on the keyboard. A phone having a hardware numeric keypad has something similar. The digit 5 also has a bump. It is also used for the same purpose. One can easily and quickly enter the digits without having a look at the keypad.

The Scoville scale is a measurement of the pungency (spiciness or "heat") of chili peppers and other spicy foods, as recorded in Scoville Heat Units (SHU) based on the concentration of capsaicinoids, among which capsaicin is the predominant component. The scale is named after its creator, American pharmacist Wilbur Scoville, whose 1912 method is known as the Scoville organoleptic test. The Scoville organoleptic test is the most practical method for estimating SHU and is a subjective assessment derived from the capsaicinoid sensitivity by people experienced with eating hot chilis. An alternative method, using high-performance liquid chromatography (HPLC) can be used to analytically quantify the capsaicinoid content as an indicator of pungency. As of 2011, the subjective organoleptic test has been largely superseded by analytical methods such as chromatography.

When the human body begins to metabolize a medication, different organs process the ingredients before they are finally released in the bloodstream. While the process may sound straightforward, different drugs dissolve at different rates, different formulas, and dosages breakdown differently and, everybody’s body metabolizes medication uniquely. These are just a few of the many complexities behind the nature of drug absorption and metabolism. The vast majority of medications are taken orally and are broken down within the gastrointestinal tract. Once the medication arrives, it is broken down by stomach acids before it passes through the liver and then enters the bloodstream. Certain medications may stay in the bloodstream longer, it all depends on the dosage and drug family consumed. Gastric acids may prevent or slow the breakdown of certain medications. Additionally, when a medication is metabolized in the liver, its potency will decrease along with its effectiveness before the therap

Both 2 stroke and 4 stroke engines are widely available in the market but for a large ocean-going merchant vessel, a 2 stroke engine is more commonly used as the main engine and has a much better market. Even with a wide variety of advantages that 4 stroke engine offers like the compact size of the plant, much more RPM or speed etc, a 2 stroke engine outshines with few but vital advantages. Fuel Selection: The fuel prices have gone sky high and better grade fuel is adding higher costs to vessel operation. A two-stroke engine can burn low-grade fuel oil and hence reduce the running cost of the ship. Efficiency: The thermal and engine efficiency of 2 stroke engine is much better than that of a 4 stroke engine. Power: Most of the 2 stroke engines are now large stroke engines that produce more power. Hence they have high power to weight ratio as compared to 4 stroke engines. More Cargo: Ship can carry more weight and hence more cargo with 2 stroke engines because of high power to weight

Xenotransplantation is any procedure that involves the transplantation, implantation or infusion into a human recipient of either (a) live cells, tissues, or organs from a nonhuman animal source, or (b) human body fluids, cells, tissues or organs that have had ex vivo contact with live nonhuman animal cells, tissues or organs. The development of xenotransplantation is, in part, driven by the fact that the demand for human organs for clinical transplantation far exceeds the supply.  Currently ten patients die each day in the United States while on the waiting list to receive lifesaving vital organ transplants. Moreover, recent evidence has suggested that transplantation of cells and tissues may be therapeutic for certain diseases such as neurodegenerative disorders and diabetes, where, again human materials are not usually available.  Although the potential benefits are considerable, the use of xenotransplantation raises concerns regarding the potential infection of recipients with both

Web 3.0 is a term that is used to describe many evolutions of web usage and interaction among several paths. In this, data isn’t owned but instead shared, where services show different views for the same web / the same data.  The Semantic Web (3.0) promises to establish “the world’s information” in a more reasonable way than Google can ever attain with their existing engine schema. This is particularly true from the perspective of machine conception as opposed to human understanding. The Semantic Web necessitates the use of a declarative ontological language like OWL to produce domain-specific ontologies that machines can use to reason about information and make new conclusions, not simply match keywords.  Web 2.0 refers to worldwide websites which highlight user-generated content, usability, and interoperability for end users. Web 2.0 is also called the participative social web. It does not refer to a modification to any technical specification, but to modify the way Web pages are des

Spiders produce silk threads to build their webs. The silk is produced in silk glands with the help of the spider's spinnerets. Spinnerets are special organs that allow the spider to decide what type of thread it needs for the web. The silk threads can be thick or thin, dry or sticky, beaded or smooth. The threads a spider uses to construct its web begin as liquid, but they dry quickly in the air. When a spider begins a web, it releases a silk thread. It anchors the thread to some object — a branch, a corner of a room, a doorframe — wherever it builds its web. As the spider moves back and forth, it adds more threads, strengthening the web and creating a pattern. Lines that go from the center of the web outward are called "radial lines." They support the web. Threads that go around and around the web are called "orb lines." When a spider catches prey in the sticky strands of its web, it approaches the trapped insect and uses its fangs to inject venom. The venom e

Red, green, blue and black are the shades that control the universe of passports and all of these have a good reason for it. There are some reasons to attribute to the choice of passport colors. The colors of the passports are limited, nations keep testing with the shades of these four main colors that may be attributed to "many possible scenarios." Blue: Countries having blue colored passports are supposed to be the part of the so-called 'new-world' League of Nations. These nations are India, North America, South America and Australia among others. Red: Red is supposed to be the color of the communist movement in all over the world. This color usually belongs to countries, which are known for having a communist history or still have its influence. Key examples of this type are China, Russia Serbia and Latvia. Green: As per the Business Insider, religious faiths play a role in the color of the passport. This is the reason; Islamic nations like Saudi Arabia and Pakista

The flame at the top of an oil rig is an iconic image for the Oil & Gas Industry, yet few people understand why companies choose to burn natural gas. By burning excess natural gas, flaring protects against the dangers of over-pressuring industrial equipment. A gas flare, alternatively known as a flare stack, flare boom, ground flare, or flare pit is a gas combustion device used in industrial plants such as petroleum refineries, chemical plants and natural gas processing plants. Flaring is undertaken as a way to remove dangerous gasses with lower harm to the environment. It is used in safely regulating pressure in chemical plants, as well as handling natural gas release in wells. Alternatives, such as piping the gas to a plant or on-site capture and use, are of great interest.

While most other mammals can sprint faster than we can (a perk of having four legs), humans have basically evolved to be endurance runners. The theory is that this made us more efficient hunter-gatherers. So what does this have to do with sweat? Well, if it weren't for how efficiently we produce and dissipate sweat, our ancestors wouldn't have been able to run long distances while hunting and we probably wouldn't be able to do things like run marathons. Sweating gets a bad rap, and, sure, it is sort of gross. But sweating is vitally important for body temperature regulation and your overall health. A person's internal body temperature generally hangs around 98 degrees Fahrenheit. There's flexibility here, but if your body gets too hot, whether it's due to the temperature outside, being physically active or having a fever, bad things can happen, for instance, heat stroke. Fortunately, your body has very sophisticated mechanisms for sensing and regulating body tem

CE stands for Conformité Européenne. It's French for European Conformity. CE marking is a certification mark that indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA). The CE marking is also found on products sold outside the EEA that are manufactured in, or designed to be sold in, the EEA. This makes the CE marking recognizable worldwide even to people who are not familiar with the European Economic Area. It is in that sense similar to the FCC Declaration of Conformity used on certain electronic devices sold in the United States.

It's amazing how much water weighs! A gallon of water weighs 8 pounds, and a pint of water (16 ounces) weighs 1 pound (in metric, 1 liter of water weighs 1 kilogram). This means that if you drink a 1-liter bottle of soda, you instantly gain 1 kilogram (2.2 pounds) from the water. That's a big weight change, and it can happen very quickly. The main thing affecting overnight weight change is the amount of water in your system. Water weighs an amazing amount. In other words, if you drink a 1-liter bottle of soda, instantly you will gain 2.2 pounds, just from the water. Overnight, two processes cause you to lose water gradually: breathing and sweating. In respiration, each time you exhale, you lose a small amount of water. If you exhale onto a cool piece of glass you will see this moisture. Through sweating, also called transpiration, you lose water through the skin. Over the course of one night, both of these processes eliminate more water than you might think. Also contributing t

Carbon footprint, amount of carbon dioxide emissions associated with all the activities of a person or other entity (e.g., building, corporation, country, etc.). It includes direct emissions, such as those that result from fossil-fuel combustion in manufacturing, heating, and transportation, as well as emissions required to produce the electricity associated with goods and services consumed. In addition, the carbon footprint concept also often includes the emissions of other greenhouse gases, such as methane, nitrous oxide, or chlorofluorocarbons (CFCs). The carbon footprint concept is related to and grew out of the older idea of ecological footprint, a concept invented in the early 1990s by Canadian ecologist William Rees and Swiss-born regional planner Mathis Wackernagel at the University of British Columbia. An ecological footprint is the total area of land required to sustain an activity or population. It includes environmental impacts, such as water use and the amount of land used

The earth pin on a plug is longer than the live and neutral pins. This means the earth pin is the first to connect and the last to disconnect. When inserting the plug, the earth connection is made before the current-carrying contacts of the plug become live. The current-carrying contacts shall separate before the earth connection is broken when withdrawing the plug . Thus, the earthing connection is always maintained to improve safety. Many wall sockets have safety shutters (see image) on the live and neutral lines to prevent children from inserting conducting materials, resulting in electric shock. Inserting a longer (earth) pin helps open the shutters, facilitating the insertion of the other two pins. These are called Earth-pin operated shutters. Though it is impossible to insert the plug into the socket upside down, one may try to insert the plug top in a misaligned position (e.g. trying to insert the earth pin into the phase socket with the other two pins further down out of the so

  James Hargreaves During the 1700s, a number of inventions set the stage for an industrial revolution in weaving. Among them were the  flying shuttle , the spinning jenny, the   spinning frame , and the   cotton gin . Together, these new tools allowed for the handling of large quantities of harvested cotton. Credit for the spinning jenny, the hand-powered multiple spinning machine invented in 1764, goes to a British carpenter and weaver named James Hargreaves. His invention was the first machine to improve upon the spinning wheel. At the time, cotton producers had a difficult time meeting the demand for textiles, as each spinner produced only one spool of thread at a time. Hargreaves found a way to ramp up the supply of thread. Key Takeaways: Spinning Jenny 1. Carpenter and weaver James Hargreaves invented the spinning jenny but sold too many before he applied for a patent. 2. The spinning jenny wasn't only Hargeaves' idea. Many people were trying at the time to invent a devic

Quantitative methods for the analysis of human hair growth and hair loss are necessary for patient follow-ups or to determine the efficacy of hair growth promoting drugs.  While reviewing the capabilities of the different methods, the common theme emerges that most techniques are of little practical use to the clinician because they are time consuming, costly, or difficult to perform. An operator- and patient-friendly, inexpensive, validated, and reliable method for assessing hair growth was therefore a rational need.  With TrichoScan, such a tool is now available. TrichoScan is a software-based method for the analysis of human hair. For this purpose, digital images are taken from the scalp with a specially developed camera-optics system. TrichoScan software is then used to automatically calculate important parameters of hair growth, such as hair density or thickness from the images.

Root canal treatment is for the pulp of your tooth once bacteria have reached the pulp causing it to become infected. Root canal treatment helps preserve your tooth as long as possible so that you do not have to have it removed.  The affected tooth is anaesthetized with a local anaesthesia. Tooth is then drilled, to reach the pulp chamber and to have access to the pulp chamber and root canals. Fine instruments are used to reach the root canals and to clear the infected tissue. These are called reamers, files and are available in various dimensions. Files of suitable sizes are used for mechanical cleaning and shaping of the canals. The files used can vary from 0.06 mm to 2 mm in diameter. To give you an idea, the thickness of human hair varies from 0.02 mm to 0.2 mm, so a dental file is finer than a thick strand of human hair. Irrigating solutions help to dissolve and flush out the tissue and toxins of organisms. These solutions aid in chemical cleaning of the canals.    Now the tooth i

Chemotherapy is a drug treatment that uses powerful chemicals to kill fast-growing cells in your body. Chemotherapy is most often used to treat cancer, since cancer cells grow and multiply much more quickly than most cells in the body. Chemotherapy circulates throughout your body in the bloodstream. So it can treat cancer cells almost anywhere in the body. This is known as systemic treatment. Chemotherapy kills cells that are in the process of splitting into 2 new cells. Body tissues are made of billions of individual cells. Once we are fully grown, most of the body's cells don't divide and multiply much. They only divide if they need to repair damage. When cells divide, they split into 2 identical new cells. So where there was 1 cell, there are now 2. Then these divide to make 4, then 8 and so on. In cancer, the cells keep on dividing until there is a mass of cells. This mass of cells becomes a lump, called a tumour. Because cancer cells divide much more often than most normal

A nerve conduction velocity (NCV) test is used to assess nerve damage and dysfunction. Also known as a nerve conduction study, the procedure measures how quickly electrical signals move through your peripheral nerves. Peripheral nerves start where the nerve root takes off from the spinal cord. These nerves help control your muscles and experience the senses. Healthy nerves send electrical signals more quickly and with greater strength than damaged nerves. The NCV test helps doctor differentiate between an injury to the nerve fiber and an injury to the myelin sheath, the protective covering surrounding the nerve. It can also help doctor tell the difference between a nerve disorder and a condition where a nerve injury has affected the muscles. Making these distinctions is important for proper diagnosis and determining course of treatment.
