ADHD, or attention-deficit hyperactivity disorder, is a challenging disorder that causes behavioral difficulties. Children with ADHD are usually diagnosed in early childhood, but some might not be diagnosed until adolescence. ADHD affects at least one to two teens in every school classroom, according to the American Academy of Child & Adolescent Psychiatry, or AACAP. Teens with ADHD may experience difficulties in a number of areas, including socialization, academic performance and behavior. But with proper treatment and parental intervention, teens with ADHD can lead happy, productive and normal lives.
If your child has symptoms of inattention, impulsivity or hyperactivity which have persisted for at least six months in multiple settings he may meet the Diagnostic and Statistical Manual IV - Text Revision diagnostic criteria for attention deficit hyperactivity disorder. Simply stated, ADHD is a neurobiological condition involving reduced dopamine activity that results in developmentally inappropriate behaviors or lagging skills. If your child has ADHD he will likely need additional support and training in these skills to reach his full potential.
Although onion and garlic both may seem like totally harmless everyday kitchen staples to you, they are in no way safe for your cat -- or dog, for the matter. Not only are onions and garlic both poisonous to pets, so are all of their "relatives," from leeks to scallions.
Gardeners in the cold-winter climates of U.S. Department of Agriculture zones 5 though 7 may have given up the idea of having a citrus tree in their own yards, but with Poncirius trifoliata it is possible. Hardy down to negative 15 degrees Fahrenheit, the hardy orange tree grows from 8 to 20 feet tall and features glossy green leaves and fragrant white flowers followed by small yellow fruit. The fruit is edible, but quite tart and seedy. Its lemon-flavored peel is often used in marmalade and the fruit can be squeezed for its juice, which is high in vitamin C.
If you cat does not appear to be ill but sneezes constantly and seems to have difficulty breathing, you may begin to suspect an obstruction. One condition that can cause these symptoms is nasopharyngeal polyps. These growths can cause progressively difficult breathing and eating difficulties, and can lead to more serious problems like anorexia and neurological disorders. If you detect signs of nasopharyngeal polyps in your cat, you should consult with your veterinarian about the best course of treatment.
Basement walls are constantly acted upon by pressure from the wall’s exterior due to the dirt piled against the walls outside the structure. While most walls hold against the pressure, those that begin to give in can bow inward, developing cracks that can lead to moisture running through the walls, or weaken the structure of the wall, threatening collapse. Adding support beams to the walls can brace them against the pressure, strengthening the wall to avoid further inward movement.
The tibia and fibula are two long bones that make up the lower hind leg of cats. Otherwise known as the shinbone, the tibia commonly fractures due to trauma or disease. Any broken bone can cause a substantial amount of pain. Cats will typically try not to show they're in pain when they're unwell. Knowing the symptoms of a broken tibia may help you recognize the condition and seek immediate treatment for your pet.
Providing support for a decaying staircase can lengthen the life of the structure until finding a more permanent solution. For an outside deck, decaying wood can threaten the integrity of the entire structure. Adding a wood brace underneath a staircase can strengthen the structure as a whole but is still only a temporary solution.
The pancreas is an organ in the abdomen that provides enzymes that are critical for normal digestion. It also produces insulin to control blood sugar levels and metabolism. When the pancreas doesn’t function properly, your cat can develop diabetes or be unable to digest food properly. Pancreatic insufficiency can present as a number of signs and symptoms that indicate your cat requires medical attention.
Freon consists of a pressurized gas and lubricant used to provide cooled air to a vehicle passenger cabin. Most vehicles today, and all with a production date post-1994, use R-134a refrigerant -- some manufacturers switched to R-134a as early as 1992. R-12 refrigerant was used in most vehicles with a production date of 1994 or earlier and has been phased out of production, though recycled R-12 is available to licensed professionals. The basic components of an automotive air-conditioning system includes the compressor, evaporator, expansion valve, condenser and accumulator, along with hoses and fittings. When the air-conditioning system has lost all…
A sloping foundation refers to any underground structure that is leaning to one side. The causes of this are many, and include improper drainage, the age of the concrete or wood, poor soil or the constant toll of the freeze-thaw cycle. Fixing a sloping foundation is called underpinning. This process is normally time-consuming and expensive, but it can be done. Normally this is a matter of highly skilled labor, but some careful do-it-yourselfers can accomplish this.
A refrigerator condenser is responsible for removing heat from inside your fridge and transferring it to the outside. The condenser is usually located in the back of the appliance, and it is attached to the evaporator through a series of tubes, usually made of copper. Refrigerant flows from one device to the other. If your condenser stops working, you'll notice changes in your fridge right away.
A relay is an electrical switch used in many household appliances. It creates a small electromagnetic field that allows one circuit to switch over to a separate second circuit, essentially moving between two entirely different activities. Because the connection uses the EM field instead of the electrical current itself, it is more dependable than the electrical flow. Refrigerators use relays when operating their refrigerant cycles. If the relay fails, the results are usually seen in the motors or in the overall operation.
The crankcase breather, also known as the PVC valve, traps emissions from your lawnmower's gas combustion engine and redirects them away from the engine. This protects the engine from corrosion and reduces pressure in the engine system. If the breather fails to work properly, the lawnmower will emit excess exhaust and the engine will eventually fail. Catch breather problems before they become serious so you can save your engine.
Flooding is a problem mostly associated with older car engines. Newer cars almost all have a computer-controlled fuel injection system. This ensures that the engine is not flooded with more fuel than it requires in most situations. However, mistakes that cause flooding happen even on those engines occasionally. Look for these telltale signs to help let you know if your engine has flooded.
A garage roof frame is a structural component of a freestanding or attached garage that joins the walls and forms a base for the roof, which seals off the space from the elements. You can add supports to a garage roof frame in two different ways for added strength and load-bearing ability.
Laser printers contain a drum that applies the toner to create the images and documents that you print. The laser charges the drum in specific areas to create your image. As the drum turns, the toner attracts to the charged areas. As the paper passes over the drum, the toner transfers to the paper. This makes the drum a critical part of the printer. When the drum goes bad, the printer won't work correctly.
A screen that gets gradually dimmer, a monitor that flickers when you turn it on, or a display that flashes before going dark are all indicative of an LCD with a failing backlight. Most LCD screens require a third-party backlight, so at some point, you'll need to deal with lamp failure for your screen.
Leaking toilets are often troublesome when attempting to identify the source of the leak. If after inspecting the toilet bowl, hardware and seat for cracks or broken parts you are left with one option as the source of the leak – the seal between the toilet and the plumbing underneath. Troubleshooting a leaking seal involves the process of elimination to find the exact cause. Once found, the problem is readily repaired.
Over time, the stairs in your home will start to show signs of aging, and the treads might actually sag. The treads are the horizontal part of the stair that you step on when going up or down. The vertical parts that the treads sit on are called risers. The treads and risers are attached to a carriage on the underside of the staircase that runs all the way up on either side. If you find that your stairs are sagging, perform a few basic at-home fixes to get them back to level.
Rafters aren't the only boards that keep your roof from falling in from the weight of rain or snow. To create a more stable roof, a king truss installed from the peak of the roof vertically down to the base of the roof, provides additional stability. However, you can also add additional angled support beams off the base of the king truss to give even more stability to your roof.
Managing the books for your business does not mean having to spend thousands of dollars on accounting software packages and general ledger creation. When you have a small business with moderate expenses, Microsoft Excel's ledger templates provide accounting tabs to monitor all of your expenses, with a summary sheet that provides a rolling balance of expenses at a glance. Understanding how to post expenses to the Excel ledger templates will help ensure that you track all of your expenses properly for accurate tax reporting.
A collapsing roof is very dangerous and often causes loss of life. As a result, it is vital to inspect your home regularly and be aware of any structural damage that might lead to possible roof failure. Extreme weather is a common cause of roof collapse. Evacuate the home as soon as signs of a possible collapse start appearing.
There are a number of signs and symptoms that employees exhibit when resisting change. These signs are usually obvious but not always overt. Workers resist change because they may lose job status or authority, or believe the change is temporary, according to senior business consultants at Business Performance. Employees may also dislike or mistrust new management during a merger or take-over. Management can do much to alleviate resistance by taking a structured approach to change, providing valid reasons for it and properly communicating all changes to their employees.
Safety is always the No. 1 priority for any family. This is especially true when it comes to fires. There are various fire retardant measures that reduce the chance of fire spreading out of control in a home. Fireproofing the home's carpets is one preventative measure worth considering. While carpet can be treated with fire retardant chemicals upon installation or by the homeowner, there is no completely fireproof carpet. Carpets and rugs that are considered “fireproofed” may have the ability to extinguish a small fire. However, in case of a strong fire, fireproofed carpets will only slow down the progress…
Cyberbullying is the use of technology such as cell phones and computers to bully, threaten, embarrass and harass other individuals. The term "cyberbullying" refers to the targeting of children and teens. When an adult is bullied, it's defined as being cyber-stalked or cyber-harassed. With the anonymity of the Internet, cyberbullies at times can be difficult to track down. However, there are certain signs and symptoms that can help you determine if your child is being cyberbullied.
The drain valve in a dishwasher regulates the amount of water in the unit at any given time and also removes the dirt washed from the dishes during the cycle. When this part of the dishwasher breaks down, several signs are visible. While some of these symptoms are mild annoyances, others make the dishwasher virtually unusable.
Zucchini is a warm-season crop commonly grown in home gardens. It can be a prolific crop when grown under favorable conditions, often yielding an abundant amount of fruit, which can be eaten raw in salad or cooked in a variety of dishes. While zucchini is a fairly easy vegetable to grow, the fruit may rot under some conditions.
In automotive disk brake systems, pressing the brake pedal generates hydraulic pressure in the brake lines and actuates a piston in a caliper at each wheel. The piston pushes the disk brake pads into contact with the brake rotor, stopping the vehicle. A common malfunction in disk brakes is a stuck piston in the wheel caliper. Inserting a caliper spreader between the brake pads to press the piston back into the caliper can release a frozen caliper piston. A new caliper or an overhaul of the existing caliper is required to prevent recurrence. Symptoms of a stuck caliper are definitive…
Like dishwashers and other kitchen appliances, many of a refrigerator’s functions are partially dependent on gravity. Because of this, a change in the center of gravity can cause problems in the inner workings of a refrigerator. These problems exhibit several visible signs that will persist until the problem is solved.
Although all kids are different, they have one thing in common -- they all want their parents' attention. Your kids constantly crave your attention and can't wait to see your reactions to the things they do. Dealing with your kids' demands for attention is part of the parenting gig, but many parents don't even get the chance to figure out why their kids want their attention so badly. Understanding the way your child's mind works can help you to be a better parent.
A PlayStation 3 receives system updates from Sony. The console is vulnerable to bricking during the update process, meaning it is rendered completely unusable, especially if you lose power while the system is adding the update to its operating system. After the PlayStation 3 bricks, you can identify whether it is completely nonfunctional or whether you are dealing with a hardware issue at the same time.
The motherboard setup utility allows you to change the basic configuration of your computer by adjusting settings such as the system date and time. A complementary metal-oxide semiconductor memory chip saves these settings when the computer is off using a trickle of power from a battery. If the CMOS battery is weak or dies, the computer displays symptoms letting you know that it is time to change the battery.
Strawberries offer sweet flavors and loads of vitamins, but high levels of pesticide residue on the fruit can counteract these health benefits. Compared with most other commercial fruits, strawberries are sprayed heavily with pesticides and are susceptible to pesticide penetration, so they probably contain some residue if not labelled "organic." Consumers might notice that strawberries grown with pesticides lack sweetness, while growers may see crop damage on strawberries sprayed too heavily with the chemicals.
Classroom quiz shows can be beneficial to students for many reasons. Hands-on activities, rather than a lecture-based style of learning, help students maintain focus and develop essential problem-solving skills. Students will find a classroom quiz show to be engaging and exciting.
With the constant warming and cooling that goes on within your air conditioning system, it is reasonable to expect some condensation to occur. At the outside unit, condensation goes down a drain and is directed away from the machine, and the inside air handler works in a similar way, with the drain directing the condensation into a catch pan. When the drain clogs on either unit, the condensation pools inside and can cause problems. A quick inspection of your home will likely show signs and symptoms of a clog of this type.
As a musician, one of the most tiring things to do is to bring your instruments to a venue. If you are percussionist who plays a range of percussion instruments, taking your instruments with you to an event can be even more tiring because you have to lug multiple pieces around. One convenient way to transport a percussion set is to use a cart. That way, you only have to pull a cart from one room to another, without having to carry anything.
Modern waste water plumbing systems utilize vents in their design to allow air to enter into the drainage system. Modern drain vents are typically constructed of rigid plastic PVC or ABS pipe and protrude through a building's roof line. Regional plumbing codes dictate vent size and height. Occasionally, and for different reasons, partial or complete blockage can occur in drain vents. The resulting symptoms are typically easy to spot.
Citrus trees, grasses, palm trees, ornamentals, vegetable plants and greenhouse foliage are all susceptible to whiteflies. These insects are tiny, white, moth-like insects that procreate often. Inconspicuous gray or yellow eggs are laid in semi-circles on the undersides of leaves and hatch within two days. The larvae molt into legless nymphs and begin feeding until they pupate on the leaf. The life cycle takes 20 to 30 days and happens during warm weather. Numerous generations are born each year, which cause rapid infestations.
The power supply unit, or PSU, in your desktop computer is responsible for drawing power from an outlet and delivering it to the computer's components. If the PSU begins to fail, your computer may become unreliable or stop turning on entirely. Learn the symptoms of PSU failure to know when your computer's power supply needs to be replaced and avoid wasting money by replacing the incorrect component.
Adults often need to interview children during custody battles and crime investigations. The National Household Education Survey reports that children with multiple risk factors, such as single parents or parents that have dropped out of high school, have shorter attention spans and more propensity for extreme restlessness than their peers with minimal risk factors. It is therefore likely that you will need to interview children with short attention spans often when dealing with at-risk populations, or children involved in a crime or crisis.
To add a sign-up form to your page, you need to use the FBML app. Although FBML supports the use of forms, it does not have built-in form functions. You can create a form using the mailto action for submission, but it will open the form contents in the submitter's email program for him to send. If you have your own Web space, using an externally hosted PHP mailer is more streamlined and sends data directly from the browser. HTML Form Guide offers a simple PHP script that can be modified to work with Facebook.
Adding dollar signs to your currency lets you easily recognize financial data, even among a sea of other numerical figures. Although you can directly enter dollar signs before figures within the cell, this does not always work, particularly if the a format has been manually applied to the cell. Furthermore, manual entry is unnecessary extra work. Instead, save time by using Microsoft Excel's Format Cells feature, which allows you to add dollar signs to numerous cells simultaneously.
A boiler system heats water for your hot water system or turns the water into steam to use as heat during cold weather. One problem that causes the boiler to quit heating water is overfiring. A boiler overfires when the burner begins burning more fuel than necessary, prematurely kicking off the thermostat before the water is heated.
When a child who has performed well in school suddenly starts bringing home lower grades than normal, parents should be concerned. Threats, punishment and bribes are not appropriate. Poor grades are a red flag that should alert parents and teachers that something in the child's life is interfering with schoolwork, and that the problem must be investigated and dealt with.
Considered one of the ultimate surviving plants, mesquite trees can thrive during just about any weather condition. Found typically in the desert, they tolerate heat, sandy soil and drought. The only thing they don't tolerate is overwatering. Mesquite tree owners often mistake dormant trees as dead or dying, even though the trees are hard to kill. It is easy to tell when one of these trees is dying because they have distinct signs.
Chemists have invented several different ways to measure the polarity or uneven distribution of electrons in molecules. You can measure the dielectric constant, for example, which measures its behavior in an electric field. Alternatively, you can measure its partition coefficient. Partition coefficients using water and octanol offer one relatively straightforward way to measure non-polarity or hydrophobicity, and they are especially useful in pharmaceuticals research.
HCl and HF are chemical formula for hydrochloric and hydrofluoric acids. These two structurally similar inorganic acids have different properties. Hydrochloric acid completely dissociates in water, forming chloride and hydrogen ions, but HF is a weak acid that insignificantly dissociates in water. Distinguishing between these two compounds is a frequent laboratory assignment in chemistry. Silver nitrate (AgNO3) is a distinctive reagent for chloride ions that allows you to accomplish this task.
An absorption spectrum is a little like a fingerprint: it's unique to a given compound. Consequently, you can often identify compounds based on their absorption spectra and figure out the concentration, or the amount of the compound present. The tool you need for this measurement is called a spectrophotometer. Many spectrophotometers are designed to either measure absorbance at a specific wavelength, or to collect absorption data across a spectrum of different wavelengths.
One of the most overwhelming aspects of parenting is learning how to get a child to pay attention and listen. If your child seems to be interested in everything under the sun except for what you have to say to him, discipline can be extremely frustrating and discouraging. Increase your child's attention span and get him to listen to you -- without delay or argument.
