julfa beds at zal section, northwest iran, with 33 meter thickness, are composed of gray, cream to red limestones, nodular in some parts with intercalations of green, gray to red shales. they are very important because they are very rich in the late permian brachiopod. this research, which is focused on the mentioned fauna from the zal section, is led to identification of 38 species of 21 gener...

BACKGROUND While light has proven an effective treatment for Seasonal Affective Disorder (SAD), an optimal wavelength combination has not been determined. Short wavelength light (blue) has demonstrated potency as a stimulus for acute melatonin suppression and circadian phase shifting. METHODS This study tested the efficacy of short wavelength light therapy for SAD. Blue light emitting diode (...

A 39-year old man had periodic paralysis due to hypokalaemia. Investigations led to the diagnosis of distal renal tubular acidosis (dRTA) and Southeast Asian ovalocytosis (SAO). Both can originate in mutations of the anion-exchanger 1 gene (AE1), which codes for band 3, the bicarbonate/chloride exchanger in both the red cell membrane and the basolateral membrane of the collecting tubule alpha-i...

Indoor farming is becoming a popular alternative approach in food production to meet the demand of a growing world population. Under this production system, artificial light provides the main source of illumination in sustaining plant growth and development. The use of light-emitting diodes (LEDs) is a popular source of artificial light for indoor farms due to its narrow light spectra, modular ...
