Citations measure an aspect of scientific quality – the impact of publications. Percentiles normalize the impact of papers with respect to their publication year and field without using the arithmetic average. They are very suitable for visualizing the performance of a single scientist. Beam plots make it possible to present the distributions of percentiles in the different publication years co...

Anthropometric indicators of body composition, reflective of fat and lean compartments in pregnant women, undergo changes throughout gestation. The adequate interpretation of these indicators requires the availability of percentile distribution values for each week of gestational age. The objective was to determine the percentile distribution for subcutaneous skin-fold thicknesses: biceps, tric...

The study evaluated the effect of four treatment compositions on plasticity tropical red soil (Lateritic soil) admixed with Bacillus coagulans (B. coagulans). Samples for Atterberg limits test were prepared using compositional variables. They include 25% B. suspension and 75% cementation reagent, (25%B /75%C); 50% reagent (50% B /50%C); (75%B /25% C) above three being in equivalent volumes corr...

We evaluated the relation between term low birth weight (LBW) and ambient air levels of carbon monoxide (CO), particulate matter up to 10 microm in diameter (PM(10)), and sulfur dioxide (SO(2)). The study population consisted of singleton, term live births (37-44 weeks of gestation) born between 1 January 1994 and 31 December 1996 in six northeastern cities of the United States: Boston, Massach...

The relationship between Forced Expiratory Volume in one second (FEV1) and the Forced Vital Capacity (FVC) is intensively used in diagnosing because of its quantitative description with the index FEV1/FVC. There is not such index for the relationship between airflows (Peak Expiratory Flow (PEF) and Maximal Expiratory Flow at xx% of FVC (MEFxx, where xx=75, 50, 25%)). Our aim was to describe tha...

Measurements by ultrasound of the biparietal diameter of the fetal head during pregnancy are a reliable guide to fetal growth. As a ready means of comparison with the normal we constructed from 4,170 measurements in 1,394 cases a curve showing the percentiles distribution of biparietal diameters for each week of gestation.

background: childhood obesity could induce some risk factors for cardiovascular disease (cvd) including serum lipid abnormalities, hypertension, and atherosclerosis. the present study aimed to comparison the lipid profile in normal children with cases having overweight, obesity and central obesity . methods : i n this case control study , which was conducted 2013 , serum lipids for three groups...
