Fermentation is the metabolic breakdown of biological chemicals. The process is used to make bread, liquor, beer and wine, as well as ethanol fuel. Yeast, a type of fungus, causes fermentation of the raw materials necessary to produce these things. When discussing fermentation with grade schoolers, explaining the process of fungal fermentation using yeast can be centered around experiments with rising dough.
Root aphids are small, subterranean pests that infest several common garden plants, such as asters, sweet peas, primrose, calendulas as well as corn and strawberries among others. Root aphids are smaller than their above-ground relatives and appear pale green to yellow in color. While the insects can be difficult to identify on garden plants, since they spend the majority of their life under the soil, feeding activity from root aphids produces several common symptoms on infested plants.
Speed running, also known as sprinting, is characterized by a runner's ability to cover short distances as fast as possible. On the other hand, fatigue resistant running -- also known as long distance running -- is a style of running in which a runner maintains a moderate speed over a long period of time. The ratio of slow-twitch to fast-twitch skeletal muscle fibers in an athlete's body can help determine if he is better suited for a sprinting style or a long distance style of running.
In 1930, Gerard Berchet, a researcher working for Dupont, began investigating the polymerization of 6-aminocaproic acid. By 1935, Berchet completed his work, which resulted in the synthesis of polyamide 66, also known as nylon. Today, it's difficult to imagine what the world would be like without nylon. From mountaineering equipment to Christmas decorations, nylon has become one of the most widely-used polymers. In some applications, such as in designing nylon mountaineering rope, it's important to know the fatigue strength of the polymer.
Many types of fungi exist in nature, and many of them are benign to people and beneficial to their natural environments. However, others produce spores that cause dangerous infections and compromise architecture. Prevention and removal depend on the creation of an inhospitable environment, and taking certain steps inhibits the ability of fungi to grow and thrive.
Fungi must be isolated from the contaminating influence of the wild mixed flora of the fungal habitat. Once separated from other lifeforms that overgrow, weaken, or kill the fungi, it's ready to be grown as pure strains in a controlled laboratory evironment. Some of the competing flora grow faster than the fungi and devour its food supply. The mixed flora, called indigenous microbiota by scientists, include protists, bacteria, other non-desirable species of fungi and yeast.
Black moss fungi is perhaps most well-known as an Asian vegetable. This food source is actually a terrestrial cyanobacteria, which means that it is a blue-green algae that grows in the soil. The popularity of black moss fungi -- also known as fat choy or fatt choy -- as a food source has led to some controversy concerning the environmental effect of its harvesting, as well as possible health concerns.
The spicy sensation that lingers on the palate after consuming spicy foods results from capsaicin, the chemical commonly found in chili peppers and other plants in the capsicum family. Although several methods, namely consuming dairy, starch or sugar, all purportedly alleviate the felling of “hot” spicy food imparts, only dairy contains casein – a chemical that binds to capsaicin. The casein binds to capsaicin and essentially strips it from the tongue as it passes through the mouth, leaving only a hint of spiciness on the palate.
Lilacs (Syringa spp.) are medium- and large-sized shrubs known for their large blooms of fragrant flowers. They are often bred as hybrids to enhance their health and the aesthetic qualities of their flower and foliage. Lilacs must be monitored for fungal disease regularly to prevent the onset of a serious infection. They are vulnerable to several types of pathogenic fungi that cause a variety of symptoms, some of which can be devastating. However, many common fungal ailments, like most leaf spot diseases, rarely threaten the life of their host plant and are usually manageable.
Soil is a living ecosystem teeming with multitudes of invisible residents. One cup of native soil supports billions of microscopic organisms, says Colorado State University, including bacteria and fungi. These unseen creatures have great influence on plant growth and can be beneficial, neutral or harmful. Identifying soil-supported bacteria, filamentous fungi and yeast considers form and function of the organisms.
Gardeners grow hibiscus for the tropical flair they lend to the garden. They act as magnets to nearby hummingbirds and butterflies with their big, graceful flowers. While some hibiscus species do hail from the tropics, others, such as the rose mallows, are native to the United States. When a plant grown specifically for its ornamental nature shows signs of disease, it can be distressing to the gardener. Blight disfigures the hibiscus, but if you act quickly, there are ways to stop the disease.
As people age, unwanted wrinkles and lines appear on the face due to a depletion of collagen, which keeps skin smooth and healthy looking. Wrinkles appear the most often around the eyes, and especially around the mouth area. There are many different tactics that one can take to try to slow down the aging process and smooth wrinkles. One can use semisurigcal procedures, or a variety of anti-aging creams.
Southern magnolia trees (Magnolia grandiflora) require little, if any, pruning. This is because most trees of this species develop a symmetrical form with a strong, central trunk on their own. Southern magnolias do not grow quickly and generally are slow to recover from extensive pruning. If you plan correctly for the tree in your landscape, major pruning is necessary only to correct storm damage or to grow it against a wall or other support.
The silver birch tree (Betula pendula) is also known as white birch, and it is native to the European continent. Silver birch is a quick-growing, deciduous tree that can reach heights of 65 feet. Betula pendula is grown for its attractive, non-peeling bark, which is white and turns black over time, its flowers, which appear in April and May, and its reputation for attracting wildlife. If you are fortunate enough to have silver birch trees in your lawn or garden, beware of some of the most common problems associated with the species.
The Pacific sunset maple (Acer truncatum x A. platanoides "Warrenred") is a hybrid of the Norway maple and the purpleblow maple. This hardy tree is desirable for its fast growth, colorful fall foliage and neatly rounded crown. Like all maples, it can suffer from a number of diseases, most of which are not life threatening.
Sun damage and less collagen production from aging are not the only factors to cause lines and wrinkles; years of laughing or smiling can cause lines to develop around the mouth. These lines are called laugh lines, yet they are no laughing matter. Fortunately, you can treat deep laugh lines with a variety of methods designed to give you a smoother and younger appearance. Research each one carefully, though, before you invest your money and time.
The student life of late-night partying and studying can play a real toll on your energy levels. When it comes to preparing for an exam, it can be very hard to focus on your studies if your body and mind are fatigued. Fortunately, there are ways to deal with fatigue when you have to study. Making sure you are in the best health you can be will help you pass your exams with flying colors.
The buttery yet sweet taste of fresh salmon is incomparable to frozen or store-bought fish. Whether you caught it yourself or received a thoughtful gift, a whole salmon makes a delicious meal. However, you do have to clean the fish before you can eat it. Filleting or dressing a fish means that you remove the interior of the fish so that some bones and the meat are left. Once you are finished, it's time to cook and chow down!
Homegrown citrus trees perfume the yard and enhance the landscape with their colorful fruits. Citrus trees have very specialized site, cultural and environmental requirements. They are tropical to sub-tropical and variances in the temperatures can cause injury to the plant. Citrus trees that have all their requirements met are still susceptible to a high number of insect pests, viral and fungal diseases and nutrient deficiencies that can cause bark deformities, peeling and scaling. Identification of the cause of bark problems is the first step to curing the issue.
Fatigue occurs when a material is subjected to alternating, or cyclic, stress over a long period of time. This repeated motion weakens the material in a similar manner to when you repeatedly exercise a particular muscle in your body; you become tired and unable to continue. Stress is the amount of force applied to a cross sectional area of material. The stress ratio is the ratio of the minimum stress to maximum stress that is applied. Fatigue and stress ratio are two key concepts used in the fatigue testing of materials.
Doublefile viburnum (Viburnum plicatum var. tomentosum) is a cultivar of the Japanese snowball viburnum (V. plicatum). This cultivar is one of the most beautiful variations of viburnum currently in circulation, according to the Clemson University Extension. Doublefile viburnum is vulnerable to several groups of diseases that can mar its aesthetic value and decrease its vibrancy. Some of these conditions are serious enough to cause permanent or fatal damage.
Turtles are relatively easy pets to care for. They must be well fed and their surroundings kept clean. A good diet and clean environment go a long way toward preventing illness and disease. However, despite the best of efforts, occasionally a health problem does arise, such as fungi on a turtle. With proper care, fungus on a turtle can be dealt with successfully, and the turtle can be restored to health. Not dealing with fungi on a turtle can result in serious illness, perhaps even death in extreme cases.
The Rottweiler is a large, strong dog that requires a lot of attention and sufficient training to be properly socialized and comfortable in different situations. A typical Rottweiler weighs 100 pounds or more, so trying to coerce him can be intimidating, including when trying to get him to drop an item in his mouth. With some simple techniques, though, you can confidently train him and positively reinforce your relationship with your dog.
Fatigue and somnolence, also referred to as drowsiness, are words used to describe two similar conditions commonly characterized by a feeling of weariness and a desire for sleep. While the two conditions are somewhat similar and they often coexist as a result of sleep deprivation, fatigue and somnolence are also distinctly different.
Muscles are the tissues in the body that push and pull bones and joints. Muscles are composed of smooth, cardiac and skeletal muscle fibers and utilize energy to perform physical tasks. Muscles fatigue over time after they perform work. They then require time to recover before they can act in full force once again. An accelerometer measures the acceleration of an object, and can be used to measure the acceleration of body parts as well. Therefore, it can be used to measure muscle fatigue.
The tenderest parts of a mature plant are in the new growth and buds. These areas are still developing and, like a new plant, do not feature all the defense mechanisms of the rest of the plant, such as a hardened stem or thickened cell wall. Because of this, environmental factors and pathogens can weaken and even destroy new bud growth, leaving the still developing bud to rot on the branch.
Certain factors such as overdressing an infant, teething, illness and immunizations can cause a fever in an infant. If you notice your infant feels hot to the touch, this can indicate a possible fever. To accurately take your infant's temperature, take her temperature rectally. Certain techniques can help reduce your infant's fever. However, if you have an infant younger than 3 months with a fever of 100.4 degrees Fahrenheit or higher, notify your physician. Infants over 3 months who have a fever of 102 degrees Fahrenheit or higher, as well as a fever lasting for more than a day, will…
Pine nuts, which are used in pesto sauce and sprinkled over salads and fish, have been causing problems for some consumers. Some people have experienced an unpleasantly bitter or metallic taste after eating them. The bitter taste has lingered for days, making it difficult to eat other foods. The cause of so-called "pine mouth" is not yet known, but the British Food Standards Agency and Allergy UK report it is not the result of toxins or allergies. The condition clears up after a few days, but there are some things you can do to make the bitterness go away sooner.
We all have those days where nothing seems to be going correctly and nothing seems to be getting done. It can be easy to find yourself barely treading water as you try to please everyone at work, along with your family and even your friends. Spreading yourself too thin, having too many priorities and not being organized can cause one to feel stressed as well as overwhelmed. Help overcome these overwhelming feelings by prioritizing, relaxing and focusing on your life.
Restlessness always seems to appear at the worst time, like on vacation or when you have to wake up early the next morning. Causes of restlessness include excessive stress, ADHD, dementia and numerous other neurological and environmental conditions. Persistent and severe restlessness that disrupts your daily life requires medical advice, but for periodic bouts of stir-crazy, specific activities help alleviate the symptoms.
Hib is an acronym for Haemophilus influenzae type b. Hib continues to take lives among children in developing countries and worldwide; 400,000 children annually die as a direct result. Hib is the leading cause of bacterial meningitis deaths and the second-leading cause of bacterial pneumonia deaths worldwide. Lifesaving vaccines are available for this disease; however, limited awareness of the impact of Hib has stands in the way of progress with the goal of reducing Hib death rates. It is possible to calculate Hib rates in a timely fashion, which can help affected countries to take steps in combating Hib.
Metal flavors appear in men, women and children from all areas of the world and can range from slightly annoying to extremely bothersome. They are usually harmless. A number of reasons could explain the experience of a metallic taste in the mouth. Some include dental fillings, early symptoms of pregnancy and the use of herbs. In fact, after a recent number of consumer complaints, the FDA has issued a notice addressing a metallic taste associated with pine nuts. The FDA hasn't approved all uses for herbs. Do not use them in place of medication prescribed by your doctor.
When a toddler has a fever, it's not necessarily an indication of something serious, reports Dr. William Sears on the "Parenting" website. Many fevers result from colds or viral infections. As long as your child doesn't show signs of increasing illness --- such as unresponsiveness, trouble breathing, crying when touched or moved, seizures or pain when urinating --- you can administer treatment to safely bring down a toddler's temperature without seeing a physician.
For meals typically filled with beef, pork and chicken, fish can provide a welcome alternative to an ordinary fare. In addition to providing variety, fish also can help fill important nutritional gaps. Fish such as salmon, tuna and sardines contain nutrients that may be capable of reducing inflammation, building strong bones and lowering cancer risks.
Many things can cause a person to feel overwhelmed, such as working too much at a job or taking on too many responsibilities at home. Someone who is overwhelmed may feel exhausted and allow the smallest things to irritate her. If you feel overwhelmed, take the proper steps to relieve your stress.
Flesh eating bacterial disease is medically known as Necrotizing Fasciitis (NF). While rare, the disease has garnered much press because of its aggressive nature, high mortality and grisly effects. The bacteria destroy soft tissue, interfere with blood flow and disrupt the immune system in as little as a few hours. Mortality rates can be as high as 76 percent with systemic organ failure and sepsis resulting from seemingly limited infection.
Glycoalkaloids are naturally occurring substances within the potato tuber that can cause the vegetable to have a coppery taste. The most common glycoalkaloid that is found in potatoes is solanine, which, when ingested in large amounts, can cause toxic reactions in the human system. Solanine is present in the potato and other vegetables in the nightshade family because it acts as a fungicide and pesticide.
Flesh-eating insects are not just small characters in science fiction novels. They really do exist. Feasting upon dead human flesh or living tissue, these insects are capable of eating human flesh through various means. Bugs that fall into this category include the Dermestes beetles, botflies, army ants and maggots. Maggots and the Dermestes beetles feast on dead human flesh, whereas army ants and botflies are able to penetrate and eat through living tissue.
A mineral oil emulsion is created by combining mineral oil with a powder made from the acacia tree. The mineral oil used in the emulsion is a petroleum-based product that has been refined to a state that can be safely ingested. A mineral oil emulsion is most commonly used as a treatment for constipation. It works by coating the inside of your intestinal surface and can be purchased without a prescription at your local pharmacy.
Life can be so exhausting, from feeling overworked on the job and dealing with family obligations to handling overwhelming social pressures and beyond. If you are constantly feeling intense fatigue to the point that it is taking control of your life, you need to take the appropriate steps necessary to reclaim both your mind and your body.
Chlorophyll is the green pigment found in plants that allows them to convert sunlight into usable energy through a process called photosynthesis. More specifically, chlorophyll molecules are described as photoreceptors due to their light absorption properties. There are two main types of chlorophyll, named chlorophyll a and chlorophyll b. These two different chlorophyll molecules are characterized by their varying chemical structure and specific infrared light that they absorb.
Helicobacter pylori, also known as H. pylori, is a bacteria that infects your stomach and parts of your small intestine. According to the Mayo Clinic, about 50 percent of world are infected with H. pylori. However, most people will experience no signs or symptoms of infection. Unfortunately, some people will exhibit symptoms of an H. pylori infection which can range from stomach discomfort to an ulcer. If you have chronic stomach pain, see your doctor to rule out H. pylori infection.
Compassion fatigue is a type of chronic stress or "emotional exhaustion" experienced by caregivers who frequently face the suffering of others, temporarily decreasing their ability to feel compassion. Symptoms vary by individual but commonly include apathy, sadness or depression, fatigue, sleep difficulties, irritability, difficulty concentrating or completing tasks, increased absenteeism or the adoption of unhealthy coping mechanisms, such as substance abuse. Proactive self-care may help you prevent or manage the symptoms of compassion fatigue.
Animals have long been in the service of humans; pulling wagons and plows, guarding homes, keeping food free of pests. More recently, they've become companions. People with special needs like physical or mental disabilities rely on both aspects to help them see, hear and operate in the world. Service animals give them independence that is otherwise out of reach. Dogs are traditionally the go-to animal for this role, but other species are capable of being service animals, too.
Crashing fatigue is a debilitating condition that is usually associated with menopause. The body feels completely exhausted even without physical exertion. The exhaustion may not be helped by sleeping or eating, and can cause a lack of appetite and concentration as well as depression and irritability. Crashing fatigue is thought to be caused by the hormonal changes women undergo during menopause. Successful treatment usually involves a mix of lifestyle changes and medicines.
If you suffer from extreme fatigue, you may have chronic fatigue syndrome. In addition to extreme fatigue that does not improve after sleep and rest, individuals suffering from this condition may also experience a sore throat, inability to concentrate and muscle and joint pain. Additionally, bloating, chills or night sweats, dry mouth or earache may occur, according to Mayo Clinic. While the cause of chronic fatigue syndrome is not known, treatments are available.
Pine nut mouth, which is more commonly called pine mouth, is a condition associated with the increasingly popular pine nut. The condition, which lasts anywhere from a few days up to a two weeks, leaves a bitter, unpleasant taste in the mouth and makes eating a dreadful experience. What causes the condition is unknown, and so what helps alleviate it is equally unclear. However, a few things have been reported to provide relief.
Aromatherapy involves using scent to help improve psychological and physical health. The sense of smell is directly connected to the brain, and scents of certain essential plant oils have a quick effect on the individual smelling them. Different senses produce different responses, and there are a number of scents that help improve concentration.
Most mouth injuries are caused by accidentally biting yourself while chewing. Usually, only minor cuts are incurred from biting yourself, but even in those cases, the results can be very painful. Healing usually occurs within a few days, however, there are steps you can take to treat the cut, minimize the chance of infection, reduce discomfort and help your body to heal itself.
Many people have problems with fatigue. With to busy schedules, longer work hours and keeping track of children's activities, sometimes it may feel like there are just not enough hours in the day. If you are always tired you may turn to coffee, energy drinks and sugar to keep going. It is much better for your health to find natural ways to battle fatigue.
