Adenosine Triphosphate Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do. It is present in the cytoplasm and nucleoplasm of every cell‚ and essentially all the physiological mechanisms that require energy for operation obtain it directly from the stored ATP. (Guyton) As food in the cells is gradually oxidized‚ the released energy is used to re-form the ATP so

Properties of paper Physical Properties Basis Weight or Grammage The basis weight‚ substance or grammage is obviously most fundamental property of paper and paperboard. The Basis weight of paper is the weight per unit area. This can be expressed as the weight in grams per square meter (GSM or g/M2)‚ pounds per 1000 sq. ft. or weight in Kgs or pounds per ream (500 sheets) of a specific size. Paper is sold by weight but the buyer is interested in area of paper. The basis weight is what

1. Diagnosis: How is Genital Herpes Diagnosed? In most cases where there are signs and symptoms of genital herpes‚ it is possible to establish a diagnosis test of genital herpes infection. Laboratory tests‚ which include viral culture and nucleic acid amplification tests‚ are also available. They are used to detect the genetic material of the herpes simplex virus‚ which is responsible for causing the disease. Once a person has been infected‚ an individual’s body starts to produce antibodies to genital

Background: Porokeratoma is a relatively new entity with a different pattern of cornoid lamella from Porokeartosis. First described by Walsh in 2007 as a solitary lesions‚ since then there has been only one case report of multiple Porokeratomas on the lower extremities. Herein we report a case of multiple Porokeratomas on the upper extremities. Case report: A 43-year-old man‚ presents with a 6 months history of multiple asymptomatic lesion on his left forearm. Ineffectively tried treating the lesion

For some time‚ the stronger yarn produced by the spinning frame was used in looms for the lengthwise "warp" threads that bound cloth together‚ while hand powered jennies provided the weaker yarn used for the horizontal filler "weft" threads. The jennies required skill but was inexpensive and could be used in a home. The spinning frames required significant capital but required little skill. It can also be used for many purposes for

important and necessary aspect of manufacturing operations. This paper deals with one topic in particular ‘Welding’. Welding is a process for joining similar metals. Welding joins metals by melting and fusing the base metals being joined and the filler metal applied. Welding employs pinpointed‚ localized heat input. Most welding involves ferrous-based metals such as steel and stainless steel. Welding covers a temperature range of 1500º F - 3000º F. Weld joints are usually stronger than or as strong
