This paper reports two variable-gain amplifiers (VGAs) featuring a new pseudo-current-steering gain-tuning technique. In the first VGA (VGA-I), single-voltage-controlled dual-branch current mirror is developed as standalone gain control block. second (VGA-II), NMOS transistors, which are biased by tunable voltage, integrated into conventional common-source amplifier to steer away from part of t...
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
Blood selenium and trace minerals play an important role in animal’s health and production. The aims of this study were to determine selenium effect on blood glutathione peroxidase (GPX) activity, trace minerals and weight gain in lambs. Twelve female Makuei breed were studied for 63 days in groups of control, nanoselenium (NanoSe) and sodium selenite (NaSe). Mean concentrations of GPX, Cu and ...
The objective of the present study was to evaluate the effects of inbreeding on average daily gains and Kleiber ratios in Moghani sheep. Traits included average daily gain from birth to 3 months (ADG1), average daily gain from birth to 6 months (ADG2), average daily gain from 3 months to 6 months (ADG3), average daily gain from 3 months to 9 months (ADG4), average daily gain from 3 months to ye...
Background and purpose: The newborn birth weight is an important indicator for prenatal care, general health and fetal viability. The aim of this study was to assess the relationship between pre-pregnancy BMÏ and pregnancy weight gain on neonatal birth weight. Materials and methods: Ïn a descriptive-analytical study, 16-40 years old pregnant mothers registered to prenatal clinics of Lowlagar...
The blindness and deafness resulting from cerebro-spinal meningitis have generally been considered by the profession as incurable. We have been led to the study and investigation of this class of cases by a very fortunate result obtained recently in a case of blindness, which will be detailed further on, in which, by patience and perseverance in the treatment, sight was finally restored; and th...
an air force has gained command of the air, it should maintain violent, uninterrupted action against surface objectives, so that it may crush the material and moral resistance of the enemy'-Guilio Douhet, 1921.
