Journal of Cardiovascular and Thoracic Research , 2012,
Abstract: Introduction: Hypertension is the most common medical problem affecting pregnant women during pregnancy contributing to one third of substantial maternal mortality and varieties of fetal and neonatal health problems, while representing health status of a society. This study aimed to investigate the links between a healthy life style and developing hypertension during pregnancy in order to improve healthier behaviors.Methods: In a case-control study from October 2009 to April 2010, physical activity and nutritional practices of two groups of pregnant women (220 in each group) with gestational age of 20 weeks or more, single pregnancy, without any previous medical disorders were compared. Samples in case group had pregnancy induced hypertension. Data were collected using a two-part questionnaire after obtaining informed written consents from mothers before enrollment; later the data were analyzed using the SPSS 13 and Stata software. Results: Women in two groups did not differ regarding their socioeconomic characteristics. There were no significant differences in nutritional practices and level of physical activity in pregnant women of study groups; mean score of physical activity was 54.6±14.8 in test and 57.3±15.0 in control group (P=0.06) and it was 72.9±10.3 and 73.719.5 about nutritional habits in test and control group respectively. Mean pre-pregnancy BMI was higher in case group (P=0.02); these women also had a higher percentage of previous prenatal mortality and history of hypertension.Conclusion: Results state that health during pregnancy is relevant to healthy life style especially preconceptional period; therefore employing proper strategies to improve women knowledge and attitude of the important dimensions of healthy life considering good and healthy diet and active life seem to solve the problem; this needs to unite all health workers to set proper educational programs and courses and support of health policy makers.

Iranian Journal of Pediatrics , 2012,
Abstract: Objective: Improved survival of preterm infants, beneficial effects of trophic feeding and limited data on timing management of enteral feeding for very low birth weight preterm infants requires more researches to determine the exact starting time and increased volumes. This study aims to compare early (<48 h) versuslate (>72h) trophic feeding with respect to important neonatal outcomes.Methods: In a cohort study from September 2007 to October 2008, a total of 170 preterm infants (1000-1500gram, 26-31 weeks) consisting of 125 who received trophic feeding enterally within the first 48 hours of birth(early group) and 45 fed enterally after 72 h0urs (late group), without major congenital birth defects and severe asphyxia entered the study. Bolus feeding was started in both groups at 1-2 cc/kg every 4-6 hours of human milk or preterm infant formula and was advanced 1-2 cc/kg/day if tolerated along with parenteralnutrition. Feeding intolerance, possibility of necrotizing entrocolitis (NEC), episodes of sepsis, body weight,length of NICU stay, and duration of parenteral nutrition were assessed serially.Findings: There were no statistically significant differences in the clinical and maternal characteristics ofinfants in the two groups. The time to gain birth weight (13.75±5.21 vs 20.53±6.31 (P<0.001)), duration of parenteral nutrition (9.26±4.572 days vs 14.11±6.415 days (P<0.001)), hospital stay (12.14±8.612 vs 21.11±1.156 (P<0.001)) were significantly shorter in early compared to late feeding group; none of the twogroups experienced a high incidence of late onset sepsis (P=0.73). There was 1 case of confirmed NEC in every group.Conclusion: The benefits of early trophic feeding shown by this study strongly support its use for the preterm infants without adding to complications.
ASIP Solution for Implementation of H.264 Multi Resolution Motion Estimation  [PDF]
Fethi Tlili, Akram Ghorbel
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2010, DOI: 10.4236/ijcns.2010.35060
Abstract: Motion estimation is the most important module in H.264 video encoding algorithm since it offer the best compression ratio compared to intra prediction and entropy encoding. However, using the allowed features for inter prediction such as variable block size matching, multi-reference frames and fractional pel search needs a lot of computation cycles. For this purpose, we propose in this paper an Application Specific Instruction-set Processor (ASIP) solution for implementing inter prediction. An exhaustive full and fractional pel combined with variable block size matching search are used. The solution, implemented in FPGA, offers both performance and flexibility to the user to reconfigure the search algorithm.
Spatio-Temporal Land Cover Dynamics in Open Cast Coal Mine Area of Singrauli, M.P., India  [PDF]
Imran Khan, Akram Javed
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.46057
Abstract: Singrauli is an opencast coal mining area where large scale mining activities are going on continuously, land use/land cover studies are of vital importance to observe the changes in the land use/land cover. The present study utilizes multi-spectral/multi-temporal data of Indian Remote Sensing Satellite (IRS) LISS II geocoded (FCC) of 4th May 1993 and LISS III of 4th May 2010 for thematic mapping. Survey of India toposheet 63L/12 on scale 1:50,000 were used for preparation of base map which was overlaid on the FCC for land use/land cover mapping through visual interpretation. Visual interpretation of satellite imagery led to the identification of 15 land use/land cover categories such as dense forest, open forest, open scrub, plantation, cultivated land, uncultivated land, mining pit, overburden dumps, wasteland and settlement. The ground truth verification was carried out in key areas to rectify the errors in generated maps and then land use/land cover maps were finalized. The comparative analysis of land use/land cover shows that dense forest has been degraded to open forest, open scrubs and mining pits due to the expansion of mining activity. Open scrubs has increased, overburden dumps has increased, settlement has also increased, cultivated land has decreased and changed into uncultivated land and wasteland. It has also been observed that the plantation has been done on overburden dumps and residential colonies of NCL and NTPC. It has been identified that the main drivers which has increased the rate of change in land use/land cover are mainly coal mining activities and industrial expansion.
Identification of Artificial Recharge Sites in Manchi Basin, Eastern Rajasthan (India) Using Remote Sensing and GIS Techniques  [PDF]
Subah Rais, Akram Javed
Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.62017
Abstract:

The present study is an attempt to prepare a water resource development action plan for Manchi basin in Eastern Rajasthan (India) using remote sensing and GIS techniques. Satellite data have proven to be very useful for surface study, especially in the preparation of land use/land cover and geomorphological map. Morphometric parameters are analyzed to understand the basin characteristics and its influence on the water resources for instance bifurcation ratio indicates high surface run off and low recharge in SB-I, IV, V. Low drainage density ranges from 2.41 (SB-IV) to 2.99 (SB-V) km/km2, with an average of 2.72 km/km2 showing permeable strata, dense vegetation and low relief. Analysis of shape parameters i.e. elongation ratio and circularity ratio suggest that Manchi basin is elongated in shape. Whereas, slope, geology and geomorphological mapping is done to demarcate groundwater potential zones for future exploration in the study area. Slope is inversely proportional to infiltration. Therefore, sub-basin areas having gentle slope permits less runoff and more infiltration as in alluvial plains and vice versa where hills and ridges are present. The integrated study helps in designing suitable sites for constructing water harvesting structures. Check dams, percolation tanks and nala bund are proposed at 1st, 2nd or 3rd drainage orders at SB-I and SB-IV with ravenous land (open scrub), uncultivated land, open forest & exposed rock present. Nala bund & check dam are proposed at SB-II & SB-V whereas, at SB-III check dams & percolation tanks are proposed so as to conserve the natural resources present in the basin. Finally, the best feasible water harvesting structures have been proposed within the sub-basins area using remote sensing and GIS techniques.

Akram Shahhosseini, Leila Hosseina
Open Journal of Geology (OJG) , 2016, DOI: 10.4236/ojg.2016.66042
Abstract: Our study area “Tafresh” is located in the sedimentary-volcanic belt. This work was carried out as systematic for surveying ore potentials at Tafresh base on the geology, geochemistry, laboratories studies, remote sensing, and tectonic. According to study of 109 samples, most of the area’s mineralization has been associated with Dacite, Diorite, Tonalite intrusive massive, Andesitic dykes which are related to operation of thrust and strike slip faults. Also, most of these ore deposits had been concentrated at sedimentary rocks of Cretaceous that involves Limestone and Shale in the Southwest and Andesite to Andesitic Basalt at the Northern of Tafresh area. Most of the alterations zones associated with mineralization are androgenic like Argillic, Propylitic, Sericitic, and siliceous alterations that have appropriate adaptation with area’s major faults as well. Eventually, based on the geochemical studies and incorporating all data by GIS software, Tafresh has remarkable concentration of Cu and Au ore deposits that are recognized as Skarn and Hydrothermal ore deposits which are related to fluids flowing from intrusive massive and dykes.

Journal of Power and Energy Engineering (JPEE) , 2016, DOI: 10.4236/jpee.2016.49002
Abstract: Libya is an oil exporting country located in the middle of the North Africa. Exporting oil is the major income resource for the economics of the country. Al-Zawea refinery is one of the oil refineries in Libya. It is the largest refinery in the region. The refinery located in the Mediterranean coast. Electricity is the main sector in the refinery to produce and export oil. This paper discusses the possibility of the penetration of the renewable energy (wind) generated electricity into the refinery power system. Although, renewable energy application in Libya was started in the middle of the seventies, it has still not found its way into industry sector. This study proposes the possible impacts of renewable (wind) energy system integration on the Al-Zawea refinery electric grid to satisfy the refinery load demand.
Cancer Specific Non-Synonymous Single Nucleotide Polymorphism Prediction in the Context of Haplotype and Protein Interacting Sites  [PDF]
Pakeeza Akram, Li Liao
Journal of Biomedical Science and Engineering (JBiSE) , 2017, DOI: 10.4236/jbise.2017.105B004
Abstract:
In this work, we study predicting the effect of non-synonymous SNPs on several cancers. We trained classifiers on both sequential and structural features extracted from the affected genes and assessed the predictions made by the trained classifiers using cross validation. Specifically, we investigated how the prediction performance can be improved by connecting SNPs in the context of haplotype and interacting sites of proteins encoded by affected genes. We found that accuracy was consistently enhanced by combining sequential and structural features, with increase ranging from a few percentage points up to more than 20 percentage points. The results for putting SNPs in the context of interacting sites were less consistent. Compared to individual SNPs, these that appear together in haplotype showed stronger correlation with one another and with the phenotype, and therefore led to significant improvement inprediction performance, with ROC score increased from 0.81 to 0.95. Although some similar effect has been expected for connecting SNPs to interacting sites in proteins, the performance actually got worse. This decrease in prediction accuracy may be caused by the small data set being used in the study, as many affected proteins in the study do not have known interacting sites.
