What do Control Valve Suppliers Provide for System Balance?

0
Posted by Marie on July 20, 2012 at 4:00 pm

There are a number of ways for HVAC specialists to control water flow within a closed water system, and a control valve hookup is one of the most effective ways of ensuring that pressure and flow rates are appropriate within the system.  Together with automatic and manual balancing valves, control valves help keep water conditions (like pressure and temperature) at the levels specified for that system for optimum performance.

The Control AssemblyControl Valve diagram

Though “control valve” is the most common term, people who talk about this type of valve are actually often referring to an entire control valve assembly.  Control valve suppliers may offer these parts separately or as part of an entire system.

  • The valve body
  • Internal trim parts
  • An actuator (which powers the valve in order for it to be able to open)
  • The positioner
  • Supply pressure regulators
  • Air sets
  • Switches
  • Other accessories and parts

The Control Loop

A control valve must operate on a closed system loop in order to effectively maintain water pressure and flow within the system.  In a closed loop, all components of the system (including the control valve assembly, sensors, pumps, transmission devices, and the vessel under pressure that is being controlled) are interconnected to allow for continuous feedback of information about the status of the water in the system.  This status – known as the process variable – must be carefully monitored in order to be sure that the water within the system reaches the correct temperature (called the set point).

Correct hookup of the control loop allows information to be constantly read by the system’s sensors, and this allows for the system to make automatic adjustments to water pressure, flow, and other variables in order to achieve the right temperature.

How Can I Improve My Practice’s Medical Revenue Cycle Management and Collections?

Posted by Marie on April 9, 2012 at 4:37 pm

During the economic downturn, medical practices and hospitals are seeing lower-than-ever collections rates.  There are a number of changes – both small and large – that your practice can make to improve the percentage of patients who pay and the time frame within which they turn in payments.medical revenue cycle management

  • Collect complete patient information up front.  Taking down the patient’s full name and address, phone numbers, work address, date of birth, and emergency contacts gives up front gives you the opportunity to skip-trace and keep tabs on all of your patients.  Ask for their social security number as well, though many may choose not to provide it.
  • Verify insurance information with the insurance provider.  Check on the accuracy and extent of the patient’s coverage as soon as possible, even if you’re busy.
  • Be clear about your payment schedule and policies.  Printing this clearly on the first page of the forms lets patients know what you expect up front and how failing to pay will affect them.  If you use a third-part medical collections agency, let your patients know this – many may be more likely to pay on time.
  • Consider a third-party revenue cycle management solution.  This gives you a way to turn your collections over to a medical revenue cycle management company that specializes in collections and has the resources to dedicate to your account.  Rather than having your busy office staff work on collections in their spare time, a third-party service can utilize their training to maximize your collections by working on them the entire day.

What Causes Numbness and Tingling in the Body?

4
Posted by Marie on April 4, 2012 at 9:51 am

Numbness or tingling sensations in the body are usually felt in the arms, hands, fingers, feet, or hands.   Though they are most commonly a symptom of nerve damage, a number of other problems can cause these sensations.

Putting pressure on a nerve for an extended period of time can cause odd tingling sensations and numbness in the affected extremity – this is common when a person sits or lays in an awkward position and an arm or leg “falls asleep.”  However, when tingling and numbness occur without an obvious reason, it might be due to some other cause.  Seeing a chiropractor for examination and diagnosis may benefit patients with these symptoms.

Nerve DamageNerve damage
Certain medical conditions and substance abuse problems can cause the myelin sheaths surrounding the nerves to degenerate, exposing the sensitive nerve cells and interfering with their ability to transmit electrical signals.  Alcohol and tobacco use or lead poisoning can cause this type of damage.

Nerve Injury
Direct physical damage to the nerve – especially in the spinal column – can cause tingling and numbness in parts of the body that that nerve connects to.  A neck injury could cause symptoms in the arms, and a back injury might cause symptoms to be felt in the legs.

Herniated Discs
Herniated (or “slipped”) discs result when the tough outer shell of the cushioning intervertebral discs breaks open, exposing the soft and sensitive material inside.  A herniated disc can out undue pressure on the nerves of the spinal column, causing chronic pain and numbness or tingling in the extremities affected by that nerve.

If you are experienced numbness or tingling with no explained cause, treatment from a NJ chiropractor could help pinpoint the exact cause of your symptoms.  By first identifying the underlying condition, your chiropractor will be able to treat your real problem and eliminate the discomfort of constant, unexplained numbness.

How Does a Solar Water Heater Work?

2
Posted by Marie on March 19, 2012 at 1:26 pm

With solar energy San Diego water heating systems, there are a number of available types and designs available for residences and businesses.  The right system for your Solar water heaterproject depends on the condition of the water in your area as well as your region (mostly due to the climate).

The basis of a solar water heating system is the solar collector – a device similar in appearance to a solar panel that is designed to collect the sun’s energy in water flowing through tubes in the device.  This transfer of energy heats the water, and the system may work in a number of different ways.

  1. Direct.  A direct system heats the water in the tubes directly.  It’s cost-efficient, but water could overheat or freeze.
  2. Indirect.  An intermediary fluid (known as a heat-transfer fluid) collects the sun’s energy and transfers it to a tank system, where the water is heated.  These systems are slightly more expensive.

In addition to direct and indirect heating, either type can also be passive or active.

  1. Passive.  These systems use convection energy driven by heat to move the water.  They’re less expensive, but don’t offer any insurance against overheating or freezing.
  2. Active.  Active systems use pumps to move the water through the building.  They’re efficient, but more expensive.

Your San Diego solar energy provider can help you decide which is the best system for your home or business.

Do Facet Joint Injections Have Any Side Effects?

19
Posted by Marie on January 23, 2012 at 1:18 pm

Many patients with chronic pain – especially in the neck and back – are finding pain relief with minimally invasive injection therapy.  The treatments offer a faster recovery time and quick orthopedic specialist Ocean Countyrelief from pain with up to several months of results.

Facet joint injections are an excellent treatment option for patients with chronic pain in the neck or back due to problems with the facet joints, or the small joints in each segment of the spine that help guide its motion and allow it to rotate.  Your orthopedic specialist Ocean County will numb the area with a gentle local anesthetic and inject an anti-inflammatory steroid medication directly into the facet joints causing your severe pain.  The procedure takes under an hour, and you will be able to go home that day.  Most experience results within 3-7 days of having facet joint injection NJ treatments, and your results could last up to several months.

Side effects of the treatment are very minimal in comparison with the pain and long recovery time associated with major surgery.  During the procedure, you may be slightly uncomfortable while your injections are being administered.  After the procedure, you may experience:

  • Numbness at the injection site for up to six hours after the injections.
  • Slightly worsened symptoms for a day or two following the injections, then significant relief as the treatment begins to work.
  • Less than 5% of patients could experience facial flushing, mild rises in body temperature, headaches, and bloating for 1-3 days following treatment.  These are all side effects of any steroid medication and are very uncommon with facet joint injections.

These side effects are all very mild, and the benefits of minimally invasive facet joint injections far outweigh the potential negatives.

What is Carotid Artery Disease – and What’s My Risk?

4
Posted by Marie on January 17, 2012 at 4:16 pm

Carotid artery disease is a condition that occurs when a waxy substance called plaque begins to build up in the carotid arteries – the two large arteries located on either side of the neck Exercisethat supply blood to the brain.  These arteries are fairly large, but when plaque deposits on the arterial walls begin to make them narrower, it’s considerably easier for blood flow to the brain to be blocked.

Causes of Carotid Artery Disease
Just like the arteries in the chest surrounding the heart, the coronary arteries are susceptible to hard, waxy plaque deposits building up on the inside walls.  When the inside of the arterial walls become hard and narrowed with plaque buildup, the condition is known as atherosclerosis.   Plaque consists mostly of cholesterol, a fatty substance produced by the body and consumed in food.  Your risk of developing atherosclerosis (and, in turn, carotid artery disease) is mostly based on your family history and your diet.

Mini-Strokes
While atherosclerosis of the arteries around the heart causes heart attacks, atherosclerosis of the carotid arteries is responsible for transient ischemic attacks, or mini-strokes.  During a mini-stroke, the brain is briefly deprived of blood and the patient may experience the following symptoms:

  • A sudden, severe headache
  • Dizziness
  • Difficulty seeing
  • Trouble speaking
  • Sudden numbness in the face or extremities, often only on one side of the body

A Silent Killer
Carotid artery disease often presents with no symptoms and goes completely unnoticed by the patient.  It’s extremely important to see a doctor immediately if you show any of the symptoms of a mini-stroke.  Having regular cholesterol tests and physical exams can also help your identify your risk of carotid artery disease.

According to cardiologists in Florida Cardiovascular Institute of Northwest Florida (also known as Cardiology Associates), a number of minimally invasive treatment options (like carotid artery stenting) can help reduce your risk of a serious stroke in the future.

What is “Bunching Deductions,” and How Can it Help My Tax Situation?

0
Posted by Marie on November 17, 2011 at 5:05 pm

Not everyone’s costs are sufficient to itemize their deductions, but your costs may still be significant enough that you could benefit from a different way of handling them.  Bunching yourtax preparation Encinitas deductions helps you get the most from your almost-deductible expenses and help you collect more.

How Do Itemized Deductions Work?
An itemized deduction is an expense that taxpayers can report on their tax preparation Encinitas forms to reduce the amount of money that they owe to the federal government (or increase the amount of the refund they are entitled to).  The IRS maintains a list of items eligible for itemized deduction.  Taxpayers simply subtract this amount from their adjusted gross income (AGI) to find their taxable income.

Many deductions are only allowed if they reach a minimum amount related to your AGI.  Bunching your deductions offers a way around this limit.

Bunching Your Deductions
Bunching your deductions simply means fitting as many deductible expenses into one tax year as possible.  Bunchers will need to keep track of their expenses throughout the year, and if they are falling short of a deduction by the end of the year they can prepay certain services or take care of medical expenses before the year is over.

For example, if your AGI is $50,000 then your medical expenses must total $3,750 before you can list it as a deduction.  If your medical expenses fall a thousand dollars or so short, bunching may not be an option – but if you’re only a few hundred dollars short, you could consider paying for certain medical needs in advance.  For example, you could purchase a year’s supply of contact lenses in advance or give the whole family flu shots to bring your expenses up.

What Causes Acne?

0
Posted by Marie on November 9, 2011 at 1:29 pm

Acne is caused by an excess of oil and dead skin cells trapped inside the skin, which cause it to become inflamed and swollen.Hair follicle

  • Sebum – an oily substance produced in the skin that keeps it moisturized.
  • Sebaceous glands – the glands inside the skin that produce sebum.
  • Hair follicle – the tiny organ inside the skin that produces a hair.  Attached to each follicle is a sebaceous gland.
  • Pilosebacious unit – a unit made up of a hair follicle, sebaceous gland, and hair.  Pilosebacious units are found all over the body except for the palms of the hands and the feet.  Most are concentrated on the face, neck and chest.

This condition is most common during puberty, when hormones cause increased sebum production and more oil on the skin.  Some acne is caused by bacteria that normally inhabits the follicles, but increases with increased oil production during puberty and causes an inflammatory response.  This causes red bumps known as papules plus pustules form on the skin.  Dermatologists in CT recommend washing the face twice daily with an acne-fighting wash.  During winter, cold weather can aggravate acne even further – so it’s important to wash and moisturize the face regularly.

Blackheads and whiteheads, however, are caused by excess sebum becoming trapped in the hair follicles.  Exfoliating regularly can help reduce the amount of blackheads and whiteheads, but don’t over-exfoliate.  Consult your dermatologist to learn the best way to treat your blackheads and whiteheads.

What Are the Most Common Tax Preparation Mistakes?

1
Posted by Marie on October 5, 2011 at 10:49 am

Preparing your own taxes can be difficult, and many Californians end up using a San Diego tax preparation service instead.  Though a great many Americans successfully do their own San Diego tax preparationtaxes at home, the IRS sees many of the same mistakes year after year and recommends avoiding these common errors when working on your taxes.

  1. Don’t claim dependents who aren’t actually dependents. The IRS reports a huge drop in the number of people listed as dependents on other tax returns after they started requiring social security numbers for dependents to be listed.  Though sometimes the issue of whether someone is a dependent is clear-cut, it’s often not – such as if your child is away at school or if you have a non-traditional family.
  2. Use the correct forms. If your tax situation is very complicated, it may require a large number of forms and schedules.  Be sure to use the right forms and include your 1040s and 1099 forms when filing your taxes.  For help with selecting the right forms for tax preparation Oceanside residents can consult a tax expert or visit their local library.
  3. Sign your return! An amazing number of people still fail to sign and date their tax returns, and if your return is turned in unsigned it counts as unfiled.  Be sure to check that your return is signed and dated at all necessary spots.
