For indoor lighting the glare assessment by Unified Glare Rating (UGR) is widely adopted. However, disagreement exists on how to evaluate glare of non-uniform sources. This recently gained attention with the introduction of small and bright LEDs in general lighting. Earlier studies in a laboratory set-up showed that with equivalent average luminance, discomfort glare from a non-uniform stimulus...

In airlift reactors transport phenomena are achieved by pneumatic agitation and circulation occurs in a defined cyclic pattern through a loop. In the present work, the effect of geometrical relations on gas holdup and liquid velocity, and consequently on the gas-liquid mass transfer coefficient, was studied in a 6liter airlift bioreactor with AD/AR = 0.63; AD, downcomer cross-sectional area, an...

Abstract The study of silver nanoparticles (AgNPs) fabrication has gained great interest especially for pharmaceutical applications due to its excellent antibacterial properties. AgNps are well known their inhibitory and bactericidal effects both on positive negative gram bacteria. However, the utilisation some chemical reducing agents in synthesis process can be harmful environment human body....

We present ugR optical images taken with the MMT/Megacam and the Subaru/Suprime of the Extended Groth Strip survey. The total survey covers an area of about ∼ 1 degree, including four sub-fields and is optimized for the study of galaxies at z ∼ 3. Our methods for photometric calibration in AB magnitudes, the limiting magnitude and the galaxy number count are described. A sample of 1642 photomet...

conclusions we revealed that thyroid dysfunction during pregnancy was associated with iugr and low apgar score even in subclinical forms. further studies are required to determine whether early diagnosis and treatment of thyroid diseases, even in subclinical form, can prevent their adverse effect on fetus. background maternal thyroid function alters during pregnancy. inadequate adaptation to th...
