Regular physical examinations are important for children. Many physical, emotional and developmental changes take place during the preteen and teen years, with puberty being the most noticeable. Some diseases or medical conditions are more likely to appear during this time. Scoliosis, for example, is more likely to appear during growth spurts, according to PubMed Health. Physical exams -- also called well-child checks -- can help identify problems early so they can be treated or managed.

An alkaline battery charger eliminates the need for continuously buying batteries. An old uninterrupted power supply (UPS) can be modified to become a battery charger. Tools that most hobbyists have on hand are needed, as are some basic skills in using a soldering iron. No specialized electrical knowledge is necessary.
The days when medical service providers stored images of medical scans in a file cabinet are by now long gone. The advent of digital storage resulted in the creation of a standard file format called DICOM, which stands for "Digital Imaging and Communications in Medicine." DICOM files contain both medical scan images and relevant patient information.
Ceanothus is a genus of flowering plants, the species of which is commonly known as California lilacs. While some Ceanothus species are low-growing ground covers, many more are evergreen shrubs with fragrant flowers. Ray Hartman is a hybrid of Ceanothus arboreus and C. griseus. It grows to 20 feet in height and bears glossy green foliage with a silver cast and light to medium-blue flowers. The biggest problem you might encounter with Ceanothus Ray Hartman occurs if you give it too much care.
MATLAB is a professional software package that provides pre-written functions for technical applications such as digital signal analysis. In signal processing, it is often necessary to filter a signal by altering the contribution of signals with various frequencies. A linear ramp filter is a filter that provides a linearly increasing or decreasing frequency response across a range of frequencies.
Camera film is a fragile thing. Among film's weaknesses, X-ray radiation can ruin undeveloped photographs and damage unused film. That raises risks if you travel through airport security with vacation photographs sitting in your camera. The Transportation Security Administration, and film and camera manufacturers say that if you take a few simple precautions, chemical film should be fine. The TSA also says your camera and any digital photos you've taken are in no danger.
Goldfish can adapt to a wide range of alkaline pH values, but it's best for your pets to keep the pH of the water stable. The recommended pH for the water in the goldfish tank is between 7 and 8. The higher the pH, the more alkaline the water. Increased alkalinity is a stress factor for your aquatic pets, and it can affect the health of fish in the long run.
"Critter Forge" is an online game that lets players raise unique creatures and battle them against each other in a one-on-one colosseum setting. Players can create new creature types by taking genetic samples from existing creatures and combining them in the game's laboratory. Rare creatures such as the Hydra require multiple generations of breeding to produce. Once hatched, however, these creatures are very powerful and can be used to create additional creature types.
High-alkaline cleaners feature high pH levels. Only solutions containing water can be measured for pH, according to Dawn Chemical Inc. The pH scale ranges from zero to 14. Solutions with a pH from zero to six are considered acids, with all solutions from eight to 14 considered alkaline. Solutions with a pH of seven are neutral. The higher the number on the pH scale, the more alkaline the solution becomes.
Alkalinity determination is common where the composition of water is important. Industries that fall into this category include wastewater treatment plants, manufacturing plants that use steam for heat and swimming pool monitoring. Hanna Instruments provides a test kit for alkalinity analysis with detailed instructions. The alkalinity test kit covers the concentration range of 0 to 300 ppm CaCO3. The units used to measure alkalinity are parts per million (ppm), which are also expressed as milligrams per liter.
Few flowers love strongly alkaline soil. Alkaline or basic soil has a pH greater than 7. The pH scale runs from 0 to 14. A pH of 7 is neutral, while acidic soil has a pH of less than 7. Many garden plants tolerate soil with a pH up to 7.8. But only a limited number of flowers grow successfully in more alkaline soil. Test a soil sample to determine the accurate soil pH. If the pH is 8 or higher, consider growing sweet William or other alkaline-tolerant flowers.
Learning about new concepts is often difficult if the new knowledge is only presented orally or visually. Having students engage in hands-on activities increases the likelihood that they will grasp a new concept, provided the activity is designed appropriately. Math, and especially geometry, are particularly well-suited for hands-on activities.
Pre-employment drug testing is prevalent in both the public and private sector. While most states have laws that regulate applicant drug testing, the laws for testing applicants for drugs are more permissive than for testing current employees because applicants have a lower reasonable expectation of privacy than current employees do.
One of the first, and most important, steps in garden planning is soil pH testing. Soil pH is a measure of a planting site’s acidity or alkalinity. Acidic soils measure less than 6.6, while alkaline soils measure above 7.3. Not many plants thrive in alkaline soil, as high pH levels limit plants’ ability to absorb essential nutrients and minerals. However, some plants tolerate -- or even prefer -- alkaline soil. Choose species that thrive in your U.S. Department of Agriculture plant hardiness zone.

Contrast agents or materials are substances a radiology technologist may administer during a medical test to help better view the tissues and structures in your body. Commonly used in a computed tomography (CT) scans or magnetic resonance imaging (MRI) tests, contrast agents can help doctors diagnose certain medical conditions. While a severe reaction from the substances are uncommon, side effects and adverse reactions are possible.
The anode was discovered during experiments using a perforated cathode in a discharge tube. A perforated cathode is a negatively charged electrode that allows electrons to enter an electrical device. It can also be the positively charged electrode of an electrical device that provides the current to the device.
If you want to digitally create an x-ray effect, you can use the free graphics editor GIMP to accomplish the task. GIMP has a variety of filters that, when combined, can make an image look like an x-ray, full of dark areas and glowing white lines throughout the scene. Once you have a photo or graphic you want to transform, you are ready to begin editing with GIMP.
The Bureau of Labor Statistics includes animal X-ray technicians within the category of veterinary technologists and technicians. Both of these jobs perform X-ray and other imaging techniques used for diagnosing animal illnesses and injuries. The national average salary for veterinary technologists and technicians was $31,030 with a corresponding hourly wage of $14.92 as of May 2010.
If you want to create a black-and-white image resembling what you would see with x-ray vision, you can use GIMP to make the inventive scene. GIMP has an invert effect which will give your image an extraterrestrial glow. You can then desaturate the image and adjust its brightness and contrast to achieve something suited to your particular preferences. The result will not be medically satisfying, but it can produce entertainment value.
Maya is a 3D graphic and animations processing program. It allows users to create stunning 3D graphics and rendering qualities such as light effects and particles. Mental Ray is a rendering tool for Maya that allows advanced shading and lighting details. Flickering is when the image, once rendered, has graphical errors such as dark spots or details random disappearing. Correct flickering by reducing and changing various Mental Ray rendering settings.
Radiographic technologists, better known as X-ray technicians, form a bridge between you and your radiologist. They provide your doctor the information, in form of X-rays, which helps him identify the appropriate method of treatment applicable to you. An X-ray technician is required to have at least an associate degree in radiology.
X-ray imagery presents the unseen world of the body in contrastive black and white. When commercial art and popular culture use radiographic images as artwork, the result can be a temporary style trend. Getting those images into image-editing software such as Adobe Photoshop requires some prep work to access their visual data. How you accomplish this objective depends on whether you're dealing with traditional film-based x-rays or with their digital equivalents stored in medical-imaging file formats.
X-ray technicians, or radiographers, use electromagnetic radiation to produce images of the human body's internal structure, usually for diagnostic purposes. The Oklahoma Employment Security Commission predicts that the state's need for X-ray technicians will increase by more than 23 percent from 2008 through 2018, creating 560 new jobs during that period.
If a doctor suspects you may be at risk for prostate cancer, he may ask you to take a blood test every three months. Based on your prostate specific antigen score, the doctor will be able to determine whether the risk for prostate cancer has increased or decreased. That said, many men attempt to naturally lower their PSA score before a test; but keep in mind that even a man with a very low PSA score could still be at risk for prostate cancer.
Cardiac sonographers use ultrasound to generate pictures of the heart's valves, vessels and chambers. The U.S. Department of Labor's Bureau of Labor Statistics classifies cardiac sonographers under the job category "cardiovascular technologists and technicians." Aspiring cardiac sonographers typically earn a minimum of an associate's degree to qualify for employment in this fast growing occupation.
"Backlit light" is inaccurate phrasing for the term "backlight" or "backlit." In general, backlighting is what it sounds like: something that is lit from the back. A light shines from behind a translucent or transparent object toward the viewer. In computer terms, you will often see or hear the term "Backlit LCD screen" or "LED backlighting" because computer screens and some accessories are backlit for optimal viewing.
V-Ray is rendering software developed for creating final drafts of 3D models and graphics. The system, developed by Chaos Group, is used by developers and digital artists in the film, video game and architecture industries. V-Ray has a variety of features that impact the way the final version of the image looks. It has the ability to create photorealistic renderings, but sometimes the settings need to be adjusted to fix rendering problems.
The alkalinity of a pond is important, especially to the health of any fish in it. A pond's alkalinity affects its pH, and a low alkalinity can cause the pH to swing drastically during the day, according to William A. Wurts of Kentucky State University. It takes just a few simple steps to alkalinize a pond and create a healthier environment for any fish that live there.
A Computerized Axial Tomography (CAT) Scan is a unique type of x-ray machine that will create three-dimensional internal images of your body using both a computer as well as an x-ray machine. These detailed images allow the doctor to examine and determine the progression of disease in the body, without having to use surgery, according to the website eMedicine.
Crime laboratories contain supplies of toxic, potentially hazardous chemicals that are used for processing evidence. To protect their health and safety, lab workers must follow certain precautions, which include using proper work practices, wearing protective clothing, knowing how to operate ventilation equipment and adhering to procedures for tracking and handling chemicals.
The use of an iodine-based contrast dye during certain medical tests has become an essential tool in the early detection of illnesses, such as cancer. A computerized tomography, or CT, scan is one method of looking into the body with nothing more invasive than an IV needle. A CT scan with dye can be lifesaving for a patient with an undiagnosed condition, but there can also be some problems with the use of dye.
When an individual fails to adhere to a daily toothbrushing and flossing routine, a sticky layer of bacteria called plaque builds up on the teeth. If these plaque deposits are permitted to linger, periodontal, or gum, disease results. Scaling and root planing are minimally invasive procedures and therefore usually the periodontist's first choice to stop gum disease. Often effective, these procedures carry certain limitations.
Rape is an unfortunate reality in today's society. The stigma surrounding the crime and the erroneous act of blaming the victim in some cases makes rape very difficult to deal with. After a crisis such as this, the victim of rape needs support and protection. Although there may be little you can offer directly, you can still guide the individual in the right direction and ensure that she gets proper help.
A PSA or Prostate-specific antigen test is part of prostate cancer screening. It's usually combined with a digital rectal exam and can help determine whether or not you have prostate cancer (reference 1). A PSA test, or PSA screening, as it is sometimes called, is not recommended for all patients, and should be discussed with your general practicioner or a trained medical professional, who will guide you through the process in your area and make a referral if required by your health insurance.
Chemistry students know not to handle substances in the lab without proper guidance and protection; that is because even the most benign looking liquid can be quite dangerous. One method of classifying substances is by their pH level, which is a measure of each substance's acidity or alkalinity. A little over half of the pH scale is considered a basic pH level.
Diagnostic radiography involves radioactive substances used in the treatment and diagnosis of diseases. Diagnosis may require X-rays, which are ionized radiation. Diagnostic radiography also includes ultrasound and magnetic resonance imaging (MRI), which employ sound waves and magnets, respectively, to identify problems and abnormalities. It includes the use computerized tomography (CT) scans, too, for which X-ray technology produces computer-enhanced images. Doctors who use diagnostic radiography for their patients encounter several ethical issues.
The genomes of many living organisms have sections made up of short sequences of DNA that are repeated. These sections have certain characteristics, such as differences in their bases and molecular densities, that help distinguish them from other forms of DNA. These sorts of satellite DNA, which include minisatellite DNA and microsatellite DNA, have helped with DNA analysis techniques.
The pH scale runs from zero to 14 and it measures how acidic or base a substance is. Pure water is neutral and has a pH of 7. Numbers less than 7 represent acidity, with zero being a pure acid, while numbers higher than 7 represent bases. The preferred pH for a swimming pool is 7.5, with a range from 7.2 to 7.6 being required for healthy swimming water. While you can test the water's pH yourself with a water-testing kit, you may wish to have certification in verifying the pH.
An endocavity transducer is a type of medical equipment. This piece of equipment is generally used during noninvasive, outpatient medical procedures. It allows physicians and other medical professionals to see within cavities of the human body to get a closer look at areas such as the prostate or the bladder neck. Specific instructions from medical professionals and hospital personnel should always be followed when cleaning an endocavity transducer. However, there are some general cleaning guidelines that you can follow.
Saliva samples may be tested for a variety of reasons, including to determine paternity. Your doctor may request that you collect a saliva sample to check hormone levels, or you may want to test a saliva sample yourself if you're trying to predict ovulation by watching for a ferning pattern. Whatever your reasons, collecting and testing a saliva sample is a fairly easy task.
Diagnosis and assessments of patients utilize many types of tools. Some of these tools are physical tools that can provide accurate data. Other tools are charts or information-gathering strategies that help the health care worker get a complete picture of the patient and the patient's needs. A diagnosis actually utilizes assessments as tools to obtain the proper conclusion ending in a care path for the patient.
Ultrasounds use high-frequency sound waves to take a non-invasive look inside the body. One of the most common uses for ultrasound is to check on the condition of a fetus during pregnancy. There are several different types of ultrasounds (sometimes called "levels") that give different kinds of pictures and serve different purposes.
Modern technology can be both a blessing and a curse with the amount of information it makes available to the general public. Today, with a simple saliva swipe or blood test, you can be told health information that ranges from your blood pressure level to the chance of future children contracting genetic diseases. While you might be curious to find out everything you possibly can, it is wise to first consult with a doctor. A medical professional might tell you that, if there are no preemptive steps you can take to prevent a future condition, your quality of life will…
Elevated prostate-specific antigen (PSA) levels are no reason to conclude that you definitely have prostate cancer. If the reading is between 4.0 ng/mL to 10.0 ng/mL, prostate cancer may not exist at all. These levels could indicate any of a number of problems, including a noncancerous swelling of the prostate gland called benign prostatic hyperplasia. Other tests may be prescribed or your doctor make take a "watch and wait" approach. If you have received a report of elevated PSA levels, you will still want to do what you can to reverse them.
The advantages and disadvantages of an automatic electronic defibrillator, or AED, are varied depending on the setting. AED's can be effective instruments in treating cardiac problems before medical professionals arrive, but can be impractical in some applications. AED's are encouraged by the government, but mandatory laws vary from state to state.
Manta rays can be found in all of the world's oceans except the Arctic. They are recognizable for their diamond-shaped bodies and the pectoral fins that propel them through the water. Most rays are brown or blue, but they also occur in two morph variations.
