This case study aimed mainly to understand parental involvement in children education in Al Ain. The study was guided by one main question and three sub questions and used qualitative research approach. Data for this study were collected through semi structured interviews. Six mothers and fathers of children who are studying in Al Ain governmental and private schools in different education level were interviewed to answer research questions. The study revealed that parents understand that education is lifelong process and they believe in its importance. Moreover, the study clarified that parental involvement in children education in Al Ain has different levels and shapes due to parents' gender and children age and gender. Mothers are more involving in their children education than fathers. In addition, the parents' responses clarified that they focus on parentinitiated involvement activities due to variety of barriers that affect their participation in schoolinitiated parental involvement activities.
Islam, the most misunderstood religion, bears the impact of misconceptions through powerful mass media, aligned to deceitful political and corporate interests'. Since Islam is the final message of Allah (SWT) to all mankind, scholars of Islam have stressed on the fact that 'Muslims are entrusted with the duties of Da'wah among nonMuslims. This report is intended to focus on effective Da'wah in United Arab Emirates (U.A.E) and understand the role of ICT in disseminating the Islamic knowledge to NonMuslim residents in this region. At present, statistical data covering the interest rate of nonMuslims to learn Islam is absent. Also, the availability of Da'wah mediums is through formal organizations only, hence, the gap between effective Da'wah and the nonMuslims pursuing to know Islam is distend. Due to this reason, a new media is proposed, essentially an English Radio station about Islam to address the above issues and help bridge the gap.
In this research, natural adsorbents were derived from date pits in order to test their adsorption ability in removing lead ions from wastewater. In order to maximize the adsorption capacity of the adsorbents, the effect of factors on adsorption including lead concentration, adsorbent dose, time, and adsorbent type were studied. Initial investigations were used as screening experiments in the building of an experimental design with Response Surface Methodology, which was carried out in order to quantify the effects of the factors, and fine the optimum adsorption conditions to remove the maximum amount of lead. Three adsorbent types were compared: raw date pits (RDP), date pits which had been subjected to Soxhlet extraction (SDP) and date pits which had been subjected to supercritical carbon dioxide extraction (CO2DP). It was found that all adsorbent types have a capacity for adsorbing lead, with CO2DP having the highest capacity.
Salt tolerant plants such as Arthrocnemum macrostachyum and Avicena marina are of special interest to Abu Dhabi owing to the coastal desert conditions of this region. These plants thrive in salty water conditions and can withstand the high temperatures. Previous studies and current work show that there are many applications for this plant ranging from the production of pharmaceuticals to the production of jet fuel. This research focuses on the production of high value biochemicals such as furfural as an additional application for this biomass. The study looks at the effect of harsh pretreatments on the biomass at 220C in a Parr reactor to further degrade the sugars into HMF and furfural. The biomass was characterized after performing soxhlet extractions using water and ethanol for 10 hours each . Additionally, the effect of washing on the biomass was studied to see if washing before or after pressing has an impact
In this work, Adomian Decomposition Method (ADM) was utilized to solve a steady state biofilter model proposed by Ottengraf and Van Den Oever. The method enabled us to find semianalytical expressions of pollutant concentration profiles in the gas phase and within the biofilm phase. Furthermore, the solution obtained from ADM was compared with previously published experimental data as well as the exact solution. Excellent agreement was noted which proves the validity of ADM.
The isothermal laminar flow of a Bingham fluid in the entrance region of a circular pipe has been studied previously by many authors using different approaches. As current research stands, the classical momentum integral approach provides analytical results that do not match the fully developed flow at the end of the entrance region. On the other hand, numerical results do not suffer from this shortcoming? however, no experimental data are available for comparison with the numerical results in the entrance region. The objective of this investigation is to determine the entrance region length in addition to the velocity and pressure profiles in that region using a modified momentum integral method that improves the present boundarylayer model.
Two kinds of commercial microfiltration membranes (PES and Nitrocellulose) were characterized and tested for oil in water emulsion separation. Wettability of the commercial membranes were checked through CA and UCA measurements. The top surface morphology was characterized with SEM (scanning electron microscope). Separation efficiency were evaluated by checking Turbidity of filtrates and measuring TOC value of the feed solutions and corresponding filtrates. Experimental results revealed that: 1) The commercial membranes show underwater oleophobicity, with average WCA around 145.8? for PES membrane, with average WCA around 137.1? for Nitrocellulose membrane? 2) Two different membranes present separation efficiency higher than 90% for Dodecanese in water Emulsion, higher than 98% for Hexane in water emulsions.
In this paper the performance of entrained flow gasification is compared to that of plasma gasification for the energy recovery from municipal solid waste (MSW). An entire combined cycle power plant is simulated for both technologies using the software Aspen Plus to assess the cold gas efficiency, the syngas lower heating value and the plant efficiency. While plasma gasification showed better results when compared to the entrained flow gasification, the overall plant efficiency is grater in the latter case. When pure oxygen is used as oxidizer in the reactor the maximum plant efficiency of the entrained flow gasification combined cycle plant (IGCC) is 40.7% while that of the integrated plasma gasification combined cycle plant (IPGCC) is 33%. Although the IGCC plant efficiency is greater than the IPGCC plant, the latter is considered being more practical in handling waste with highly variable composition and heating value.
Unique features of Lithium Ion batteries let them to be an interesting area to develop. Herein, Carbon Nanostructures and Iron (III) Oxide were used to improve the performance of Anode electrode. Lower Iron (III) Oxide mass loading ratio with Carbon Nanostructures electrode showed better performance electrode, where the specific capacity will be the highest.
This study is an investigation into the effects of solvent membrane interactions and stability on the cycling performance of NARFBs, particularly in relation to capacity decay/retention from active species crossover. We consider two types of membranes: Nafion 115 cation exchange membrane and a hybrid Nafion 115/SiO2, in combination with two types of electrolytes: pure acetonitrile and 84/16 vol?etonitrile/1,3 dioxolane solvent mixture.
