Thermally Activated Technology in Dehumidifiers

A dehumidifier is an appliance used for household purposes, where there's a decrease in humidity in air. Since humid atmosphere causes many health issues, dehumidifiers are used. The standard degree of humidity in the air should be 30 - 50 percent. Dehumidifiers are employed in industries to maintain a certain level of humidity.

The most common type of dehumidifier is your refrigerative or mechanical dehumidifier. In the former dehumidifier, the moist is eliminated by a coil having a little fan in it. The mechanism of the dehumidifier is when temperature decreases, the vapour pressure also decreases which results in condensation of water from the atmosphere. The refrigerated coil is subsequently utilised to reheat the atmosphere that's effective in temperature regions. If you want you can make your basement a happier place using dehumidifier for basements.

In areas where there's low temperatures and low humidity level, a particular kind of dehumidifier can be used namely "Desiccant Dehumidifier" where there's a desiccant material to reduce the humidity and it has got high affinity towards water vapour. This desiccant material is exposed to high humidity air stream to collect water vapour which in turn is exposed to reduced humidity air stream where the moisture kept can also be collected. The stream employed in the former is dehumidified and latter stream is used to regenerate the desiccant. These dehumidifiers consume heat energy to produce the impact of dehumidification. There are 2 types of desiccants namely absorbent and adsorbent. At the former, there's a chemical change when they keep water vapour. Adsorbent attract increased water molecules through the air pores present in it and there's no chemical shift. The adsorbent material often used is that the silica gel. This material can be emptied by heat at a temperature of 160 - 170 oC and the warmth required is 4800 KJ/Kg water removed.

The very compact dehumidifier called "Electronic Dehumidifier" consists of low cost components. There is a heat pump to generate a chilly surrounding and there's no noise generated as there are no mechanical parts. Spray dehumidifier is used, when the temperature of water is lower than the dew point of the air flow. This spray dehumidifier resembles an air washer.

They produce a cool surface. There's a refrigerated coil along with a lover that eliminates moisture. These thermally triggered technologies use heat energy to heat or cool the refrigerative dehumidifier. Thermally activated technology in dehumidifier can be utilized as a natural gas burner.

Dehumidifiers are used in a variety of applications. It's used in food & beverage sector as an absorption dehumidifier. In baking industry, enrobing is done by these dehumidifiers to control humidity, product cooling system is done for frost free cooling and when the product is saved, dehumidifier prevents from bacterial growth.

In cereals, when coating is done, it eliminates agglomeration. In candy business, dehumidifier is utilized while panning is done in order to improve the quality of the product. While packing the candies, it is used to improve the sanitation facilities.

In biotechnological laboratory, dehumidifiers are used for sterile atmosphere within the space. In water functions, these are used to prevent condensation, whereas a pipe gallery is utilized. All these pipe galleries are prevented from rusting, deterioration and also the life of stained pipes is lengthy. The benefits of using dehumidifier would be to remove humidity, since humid air causes many health problems such as allergies, respiratory difficulties, damage of immune system, asthma. When excess level of moisture is discovered, mold and dust mites will be formed. Thus, using a dehumidifier is very advantageous for the men and women who live in moist areas.

Getting Pregnant After Stopping Birth Control

Effective methods of birth control may be the best thing to happen to women in history aside from getting the rights to vote and being elected to public office. Birth control provided women with the power of choice when it comes to having a baby. Try the pregnancy symptoms calculator to check if you are pregnancy. Although initial reactions to birth control included worries about not being able to get pregnant later on, studies show that contraceptives do not impact fertility negatively. Depending on the contraception method used, women can conceive anywhere from a day to year after stopping birth control. 

Barrier methods

Using barrier methods like condoms, sponges, diaphragms, and cervical caps, among others does not affect a woman's ability to conceive. These methods only prevent sperm cells from reaching the  egg and fertilizing it. Barrier methods do not alter or affect a woman's hormonal cycle and ovulation process.

Provided that a woman has a normal ovulation and fertility cycle and that she relies solely on barrier methods for birth control, there is no reason she could not get pregnant after having sexual intercourse without using barrier methods. If a woman cannot get pregnant after stopping the use of barrier methods, she and her partner must submit themselves to a proper medical checkup to assess their sexual and reproductive health. 

Spermicide gels and creams

The use of spermicides in cream and gel forms does not affect a woman's ability to conceive. Usually used with a barrier method or applied directly to the genitalia as a form of lubricant, these gels and creams prevent sperm cells from fertilizing the egg by killing them at the moment of ejaculation. Similar to stopping the use of barrier methods, there is no lag time when it comes to being able to get pregnant. 

Birth control pills

Using pills or BCP as a form of birth control is a popular choice among women for its convenience and reliability. However, stopping BCP to get pregnant can be a little tricky if done incorrectly. It is generally advised that women should finish their current pill pack before stopping instead of discontinuing the intake abruptly. Since it takes months to get pill-contained hormones out the body's system and for a woman's cycle to normalize without them, it usually takes an average of eight months to a year after stopping pill intake for a woman to get pregnant.  

Birth control shots

Getting pregnant after stopping an injectable form of birth control like Depo-Provera may take longer when compared to barrier methods and birth control pills. Since the effect of a shot lasts for three months, a woman hasn't really stopped the birth control until after the third month of her last shot. Even then, getting pregnant can be difficult and may take anywhere from ten to 18 months after taking the last shot. 

Most forms of birth control, especially those listed above, are designed to be temporary and reversible. As such, there is no risk of infertility in using the said birth control methods. However, disability to conceive over time after stopping these birth control methods should be brought to medical attention.

5 Reasons You Can Get Pregnant While On Birth Control

Most women rely on popular contraception methods like birth control pills and condoms to prevent unplanned pregnancies. Although the Pill and most common forms of contraception used by men and women are highly reliable in preventing pregnancies, there is still the possibility of getting pregnant while on birth control albeit being very minimal. Below are five reasons that may cause pregnancies while on birth control:

Improper use of chosen contraception method

Most contraception and birth control methods are almost a hundred percent pregnancy-proof. Human error plays a large part why unplanned pregnancies occur among people practicing birth control. 

One such example is the improper use of the Pill. The Pill must be taken at exactly the same time everyday. Forgetting or being late in taking a scheduled Pill intake and having unprotected sex can cause a pregnancy. Also, since the Pill is taken in cycles, a disruption in the cycle caused by missed birth control pills can be tricky to correct and cause an unplanned pregnancy without a backup or alternative form of birth control. 

Condoms are also prone to misuse. Not taking the air out of the condom before putting it on can cause it to burst due the friction created by the intercourse. Also, using a condom that does not fit well can cause it to burst or slide and spill the semen during intercourse. 

Diaphragms, cervical caps, and IUDs, on the other hand, need to be checked at least once a month for proper positioning. Misalignment or improper coverage can provide little pathways for the sperm to reach the egg and start the conception process. 

Inconsistent usage of contraception methods

Inconsistency in the use of contraception methods also contribute to the number of unplanned pregnancies that occur while on birth control. Missed birth control pills or having unprotected sex without condoms “just this one time,” is enough to cause a pregnancy. Since sperm can live inside the woman's reproductive system for days, having just one unprotected encounter is enough to cause a pregnancy even if the succeeding sexual intercourse made use of contraceptives. 

Other antibiotic medications

Taking antibiotic medications have been found to affect and interfere with the efficacy of birth control pills. Antibiotic medications can decrease the levels of steriod plasma concentrations in the pills which can drastically alter their effects. If pills are taken along with antibiotic medication, it is advised that women and their partners use backup birth control methods to augment the decreased efficacy of the pills. Backup contraceptives can come in the form of sperm gels, creams, and condoms. 

Broken condoms and other barrier methods

Breakage is the prime cause of failure for barrier methods of contraception. Broken condoms and other barrier methods provide a way for the sperm to escape and reach the egg. Condoms are usually broken due to the increased friction and pressure during intercourse. Using the right-sized condoms and proper latex-safe lubricants can help minimize condom ruptures. Other barrier methods can benefit from monthly checkups to assess and maintain the right fit. 

Believing there is a safe time for unprotected sex

There is never a safe time for unprotected sex. Studies have shown that while most women get pregnant during their mid-cycle or fertile days, some also get pregnant on days that normally considered as non-fertile. As such, it is advised that protection should always be used whenever one has sex to prevent unplanned pregnancies.
