Study of TORCH profile in patients with bad obstetric history
MS Sadik
Biology and Medicine , 2012,
Abstract: Infections caused by TORCH complex - Toxoplasma gondii, Rubella virus, cytomegalovirus (CMV), and herpes simplex virus (HSV) - are causes of bad obstetric history (BOH). TORCH infections are generally mild in the mother but can prove disastrous to the fetus. The degree of severity depends on the gestational age of the fetus; when infected, the virulence can damage the fetus in the developmental stages and also increase the severity of maternal disease. The aim of this study was to evaluate the incidence of TORCH infections in pregnancy wastage in women with BOH in south Indian population. This study reports the prevalence of Toxoplasma, Rubella, CMV, and HSV-II infections in randomly selected 86 pregnant women by demonstrating the presence of immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies using ELISA kits. Immunoglobulin M antibodies were positive in six patients (6.97%) for Toxoplasma, four (4.65%) for Rubella, Nil for CMV, and one (1.69%) for HSV-II. Immunoglobulin G antibodies were positive in 18 patients (20.93%) for Toxoplasma, 25 (29.06%) for Rubella, 20 (23.25%) for CMV, and 16 (18.60%) for HSV-II. It was evident that among the TORCH pathogens, our study group did suffer from Toxoplasma and Rubella to a larger extent compared with CMV and HSV-II viruses. Hence, from this study, we conclude that all antenatal cases with BOH should be routinely screened for TORCH for early diagnosis so that appropriate intervention at early stages can help in proper management of these cases.

Energy and Power Engineering (EPE) , 2018, DOI: 10.4236/epe.2018.104012
Abstract: A linear model of three layers plane wall exposed to oscillating temperatures with different amplitudes and frequencies was built by using a physical superposition. A physical superposition of two states was performed, one state is a wall which one surface is exposed to oscillating temperature and the other surface is exposed to zero relative temperature and a second state is a wall which one surface is exposed to relative zero temperature while the other surface is exposed to oscillating temperature with different amplitudes and frequencies. Temperature distributions were introduced for different amplitudes, frequencies and thermal conductivities. It was shown that increasing the frequency value decreases the temperature penetration length, high frequency value leads to extremum temperature values changes on the surface while low frequency value allows gradually temperature changes during the time period. Temperature distribution lines where there are at the same time heat flux entry and heat flux exit were not received for the same constraint frequencies.
Temperature Oscillations into a Couette-Poiseuille Flow  [PDF]
Shalom Sadik
Energy and Power Engineering (EPE) , 2018, DOI: 10.4236/epe.2018.109026
Abstract: Following previous work that discussed temperature fluctuations without flowing media a physical model of temperature oscillations into a Couette-Poiseuille flow was built. The temperature distribution into the flow was calculated according to oscillations constraints on the upper and lower plates, and heat dissipation due to shear stresses into the fluid. The physical model deals with different temperature amplitudes and different frequencies constraints on the upper and the lower plates. A physical superposition and complex numbers were used. It was shown that when the constraint frequency increases, its penetration capacity is reduced. Increasing gap width between plates leads to increased fluid temperature values due to enlarged fluid velocity. Increasing thermal diffusivity, increases constrains temperatures penetration intensity.
A Review of Promising Electrocoagulation Technology for the Treatment of Wastewater  [PDF]
Mervat A. Sadik
Advances in Chemical Engineering and Science (ACES) , 2019, DOI: 10.4236/aces.2019.91009
Abstract: A review of the literature published on topics interrelated to electrochemical treatment within wastewater by using sacrificial anodes was presented. Electrocoagulation (EC) is a technique used for water and has a great ability on various wastewater treatments, industrial processed water, and medical treatment. It has potential in removing various pollutants such as chemical oxygen demand turbidity, ammonia, color, and suspended solid. One of the most necessities industries is Textile industries which release large volumes of wastewater that contains different dyes. Azo dyes contain strong N = N bond which is not easily broken by conventional methods. The discharge of this type of wastewater to natural watercourse can pose serious environmental impacts to aquatic life. Electrocoagulation (EC) method depends on several factors as electrode material, current density, operation time and PH. The review describes, discusses and compares the types of that electrode influencing the EC process in various wastewater and leachate. Both operating costs and electrical energy consumption values were found to vary greatly depending on the type of electrodes material and solution being treated.
Removal of Reactive Dye from Textile Mill Wastewater by Leading Electro-Coagulation Process Using Aluminum as a Sacrificial Anode  [PDF]
Mervat A. Sadik
Advances in Chemical Engineering and Science (ACES) , 2019, DOI: 10.4236/aces.2019.92014
Abstract: This work presents the highest color removal efficiency for Textile wastewater by Electrocoagulation (EC) process using Aluminum as a sacrificial anode which is presently used for the purification of many types of water and wastewater. The effecting parameters such as applied electrical current, electrolysis time and initial pH were studied to achieve higher removals. In this process, sample was taken from real effluent of reactive dyes fabric. The performance of Electrocoagulation process was carried out in batch reactor at regular interval of 20 minutes. Obtained results indicated the most effective color removal efficiency was achieved at 0.75A of applied electrical Current. They were (97.5% - 98.1%), at electrolysis time of 120 minutes, pH10, pH7 respectively and COD removal efficiency was (54 % - 65%) at 0.75A, 0.9A respectively. In this work, the initial pH did not strongly affect the removal efficiencies significantly over a wide range. Therefore, adjustment of initial pH before treatment was not required in this practical application. The power consumption was found to be 6 kWh/m3. To determine COD removal rate dependency to electrical current, a kinetic study was carried out and data were in good covenant with the first order kinetic model.

International Journal of Emerging Technologies in Learning (iJET) , 2011, DOI: 10.3991/ijet.v6i1.1360
Abstract: This study aims to investigate how pre-service teachers' visual literacy skills are affected by their use of online photo management and sharing applications like Flickr. Two approaches are used to develop the visual literacy skills of pre-service teachers through Flickr. The first is to help them decode visuals through practicing analysis techniques, and interpreting and creating meaning from visual stimuli. The second is to help them encode visuals as a tool for communication. Visual literacy tests, participants' logs, photograph evaluation instruments, and interviews are used to assess the improvement in the participants' visual literacy skills. The results of the analysis revealed that the pre-service teachers' skills in interpreting, understanding, and appreciating the meaning of visual messages were enhanced through online exchange and interaction by means of photo management and sharing applications. They were able to communicate more effectively through applying the basic principles and concepts of visual design.

Pakistan Journal of Nutrition , 2010,
Abstract: Nourishing the body is a basic human right. The literature argued that children are born with the potential to develop both physically and emotionally. However, socioeconomic and environmental factors affect the health and nutrition of many children in developing countries. Little research has been done on the dietary needs of children living in orphanages in Ghana. The main objective of the study was to determine the nutritional status, food consumption patterns and dietary intake of the orphanage children. A non-experimental, descriptive action research with a multi-methodological approach was used. This study was conducted in an orphanage in Tamale. Forty children, 22 boys and 18 girls, aged 2-18 years and 23 orphanage workers formed the sample. Methods included on site observation, completion of a standard demographic questionnaire, a validated quantitative food frequency questionnaire and anthropometric measurements. The nutritional status indicated that, 10% and 15% of the children were severely stunted and wasted respectively (<-2) Z score. The dietary intake data showed energy intakes for the children aged 1-3 years as 963 kcal, 7-10 years as 1627.4 kcal and 11-14 years as 1547.53 kcal and 15-18 years as 1540.6 kcal. Protein intake for the same age groups was 33, 52.1, 50.6 and 49.3 g respectively, with fat 27 g, 33.9 g, 31.9 g, 31.9 g and carbohydrate 150 g, 284.3 g, 269.1 g and 296.1 g respectively. The top five most frequently consumed foods were coffee (232 ml) and tea (232 ml), maize meal (109 g), bread (77 g), white rice (55 g). Protein was limited with anchovies (“Keta schoolboys”) and beans as the only source. Orphanage children are vulnerable and disadvantaged members of the community, especially if measures to provide adequate dietary intakes in terms of macro-and micronutrient are not in place. The findings indicated low intake of both macro-and micronutrients with the exception of protein. Nutritional status indicated that, 10% and 15% of the children were severely stunted and wasted respectively (<-2) Z score. The results of this study formed the basis for a nutrition education and training programme that was implemented in the orphanage.
