A 1.02nW current reference is designed with only PMOS transistors, thereby providing inherently low process variation and enabling trim-free operation. Thirty-two measured chips from 5 corner wafers in 180nm CMOS technology show an untrimmed within-wafer spread (σ/μ) of 1.6% and across-corner wafer-to-wafer spread of ±4.7%. The measured average temperature coefficient is 282ppm/°C from −40°C to...

this study was conducted to evaluate the effect of different lecithin sources and their levels on growth performance and resistance to anoxia stress of rainbow trout (oncorhynchus mykiss) alevin with initial weight of 120 ± 4.08 g for 40 days. soybean and egg lecithin at 2, 4 and 6 ? levels were added to the diets. seven treatments by three replications were used in this experiment. therefore, ...

The present study aimed to determine the effect of different organic and inorganic source fertilizers on growth performance rice. experiment was conducted at two locations: Tinh Bien Tri Ton AnGiang province with varieties landrace rice AG3 AG4. Each has seven treatment. Treatments included a combination nutrients sevenrates (F1:80-40-40+ manures 10 t ha-1;F2:60-40-40+ ha-1;F3: 40+40+40+ ha-1;F...

BACKGROUND Chronic hepatitis C virus (HCV) is associated with extra hepatic autoimmune disorders, while peg-IFNa-2a/RBV combination therapy may exacerbate these conditions. Autoantibodies to cytoplasmic structures, called rod and ring particles (RR), have strong associations with these patients and are identified by HEp-2 cells. OBJECTIVES Our purpose was to study the correlation of autoantib...

Toxoplasma gondii causes congenital toxoplasmosis in newborns resulting with fetal anomalies. Determining the initiation time of infection is very important for pregnant women and current serological assays have drawbacks in distinguishing the recently acute toxoplasmosis. Diagnosis of recently acute infection may be improved by using stage specific antigens in serological assays. In the presen...

BACKGROUND The dilemma in managing patients with low back ache lies in differentiating radiculopathy from lumbar canal stenosis. This has a huge bearing in patients being planned for surgical intervention as underperforming leads to failed back syndrome whereas over-doing leads to instability. There still remains a loophole in clinically diagnosing lumbar canal stenosis. AIM We opt to utilize...
