Assessment of Body Fat and its Relation to Growth Score for Iraqi Children

Percentage body fat is the only factor reflects the relative body composition. This search aimed to study the growth score of Iraqi children and its relation to percentage body fat. A total of 107 healthy children (53 girls and 54 boys), aged 2-12 y, were included in the present study. There were no significant differences between girls and boys in body mass index (p ?0.05) while a significant differences (p<0.05) were observed in protein, bone mineral content, body water, and free fat mass (p<0.001). The growth score ranged (0-98) with mean (45.54 ±24.96) for girls, and (1-94) with mean (55.61 ±25.37) for boys. Percentage body fat was significantly and positively correlated with body mass index and inversely with growth score in each sex group .While a non significant correlation was found between body mass index and growth score. We conclude that percentage body fat is a stronger tool than body mass index to follow the growth score and subsequently the health of children.

Design and implementation of remotely monitoring system for pH level in Baghdad drinking water networks

Many people in the recent days have suffering from number of diseases due to unsafe and impure drinking water, especially in rural areas. As typical laboratory experiments and official water quality tests take considerable amount of time to obtain results and due to non availability of a simple device that can measure such water quality parameters in real time, therefore in this paper a remote pH level monitoring system for Baghdad drinking water system is proposed. A PH level sensing and monitoring nodes are distributed at different location. These nodes are proactively measured pH level of water and send data to the maintenance center to give them overall picture about pH level via global position system (GSM). This proposed system gives a robust, low-cost and effective method for the drinking water maintenance center to measure and monitoring the water quality in real time environment

An Iterative Procedure for the Estimation of Drift and Diffusion Coefficients of Langevin Processes

A general method is proposed which allows one to estimate drift and diffusion coefficients of a stochastic process governed by a Langevin equation. It extends a previously devised approach [R. Friedrich et al., Physics Letters A 271, 217 (2000)], which requires sufficiently high sampling rates. The analysis is based on an iterative procedure minimizing the Kullback-Leibler distance between measured and estimated two time joint probability distributions of the process.Comment: 4 pages, 5 figure

Studying the impact of geosynthetic materials on the strain-stress state of soil structures applicable to the mechanics of granular media

In the modern construction industry, a solution being successfully proven is the use of geosynthetic materials, applied as semi-holders, to increase the reliability and stability of soil structures. In connection therewith, solving the issues of expanding the range of methods and approaches to predicting the behavior of such structures under the activity of surface loads is a relevant task, since this is a vital factor in evaluating the designing arrangements made, including the use of geosynthetic materials. The aim of the studies according to this paper is to expand the pertinence of the mechanics of granular media (MGM) in order to assess the reliability of decisions made in the design of soil structures from pitifully durable soils, supported with geosynthetic materials, by comparing the obtained values with the results of full-scale tests and the values obtained by the limited component strategy. For this purpose, the paper presents a comparative analysis for the results of determining vertical stresses under the bridge reinforced with geosynthetic materials and its displacement, obtained by the mechanics of granular media and the limited component strategy. The results of laboratory tests, performed in a soil tray, were taken as verification data. The actual values of vertical stresses were determined using soil pressure sensors, and the values of displacement were determined using the movement indicator of the clockwork installed on the deflection meter of a die unit. An approach to determining displacement of a reinforced bridge using the mechanics of granular media was presented for the first time. The newly presented approach to determining displacement of an bridge, reinforced at the base with geosynthetic materials, allows us to conclude on its reliability, which significantly expands the applicability of the MGM as an alternative to the use of the limited component strategy. The aftereffects of contrasting the upsides of vertical anxieties under the bridge reinforced with geosynthetic materials and its displacement, utilizing the Plaxis programming bundle and the MGM dependencies, counting when contrasted and the consequences of lab tests, are presented. Based on the results obtained, a general conclusion was made on the possibility to use the MGM dependencies in deciding the example of the pressure dispersion and the values of displacement of reinforced bridges under the action of surface loads. The paper also discloses the promising directions of research in this area of geotechnical engineering

Experimental study for elastic deformation under isolated footing

Lorentz actuators for turbulence control and underwater acoustic communications

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 2005.Includes bibliographical references (leaf 103).Lorentz actuator dynamics in a fluid are governed by the fundamental principles of electromagnetism and hydrodynamics and have several potential applications in the marine field. Two areas of interest where improvements would lead to significant contributions are the turbulence control and underwater acoustic communication fields. The ability to control turbulence is directly associated with controlling drag. Shipping industries and naval institutions are constantly seeking ways to reduce drag on marine vessels. A reduction in drag would have significant impact in the marine field allowing reduced vessel fuel consumption and faster marine travel. Experimental implementation for turbulence control was carried out at the Marine Hydrodynamics Laboratory of MIT on a flat plate setup with an integrated Lorentz actuator cassette. The data acquisition system included a dynamometer setup with integrated load cells for direct force measurements, and a Laser Doppler Velocimetry system for measuring boundary layer profiles in the flow. The results showed apparent wall shear reduction of about 30% over the Lorentz actuated cassette using the boundary layer technique but no measurable change in drag with the direct force measurement method. Most of the hardware used today in underwater acoustic communications result in a limited frequency bandwidth for data transmission and is a function of the material properties used in the design. The advantage of using Lorentz actuators for underwater sound transmission is that the frequency bandwidth is controlled by the electronics which allows us to select broader ranges of frequency transmission. A hydrophone was used to quantify acoustic noise in a conducting fluid 100 mm from the surface of a Lorentz Actuator, and was measured to be 160 dB at a frequency range from 1 kHz to 20kHz. This frequency range was limited by the driver electronics available at the time of testing, however we expect an actual range up to 100 kHz with our new equipment.by Daniel A. Sura.S.M
