Fasting ramadan in kidney transplant patients is safe
Boobes Yousef,Bernieh Bassam,Al Hakim M
Saudi Journal of Kidney Diseases and Transplantation , 2009,
Abstract: Muslims with renal transplant often ask their doctors whether fasting Ramadan is safe. Scanty studies have addressed this question. This prospective study was undertaken to identify any clinical or biological changes with Muslim fasting. 22 kidney transplant patients with stable kidney functions, who were transplanted for more than one year, and voluntarily chose to fast during Ramadan in 1425 H (October-November 2004), were studied. Total of 22 subjects (10 men and 12 women) with a mean age of 47 ± 11.6 years were studied. Full clinical and biological assessment was done before during and after the month of Ramadan fasting. Medications were taken in two divided doses at sunset (time of breaking the fast) and pre dawn (before the fast). None of the patients experienced any undue fatigue, or symptoms. Body weight, blood pressure, kidney function tests, blood sugar, lipid profile, and cyclosporine levels remained stable. In conclusion it is safe for renal transplant recipients of more than one year and having stable graft function to fast during the month of Ramadan; however caution is advised for moderate to severe impaired renal function.
Fasting Ramadan in chronic kidney disease patients: Clinical and biochemical effects

Saudi Journal of Kidney Diseases and Transplantation , 2010,
Abstract: Fasting of the month of Ramadan is a pillar of Islam. Muslim patients with chronic kidney disease (CKD) usually fast this month. To determine the effects of fasting on renal function in CKD patients, we prospectively studied 31 (19 males and mean age 54 ±14.2 years) CKD patients during the month of Ramadan 1426 Hijra (4 th October - 4 th November 2005); 14 patients were in stage III CKD, 12 had stage IV and 5 had stage V. The mean estimated glomerular filtration rate (e-GFR) was 29 ± 16.3 mL/min. Diabetes was the main cause of CKD (19 (61%) patients), and hypertension was present in 22 (71%) patients. Clinical assessment and renal function tests were performed one month prior to fasting then during and a month later. Medications were taken in two divided doses at sunset (time of breaking the fast) and pre dawn (before starting the fast). All patients fasted the whole month of Ramadan with a good tolerance, tendency to weight reduction, and lower systolic and diastolic blood pressure. eGFR showed a significant improvement during the fast and the month after. The blood sugar was high during fasting with an increment in the Hb A1c. There was better lipid profile, reduction of the pro-teinuria and urinary sodium. We conclude that this study demonstrates a good tolerance and safety of fasting Ramadan in CKD patients.
Composition and Band Gap Controlled AACVD of ZnSe and ZnSxSe1-x Thin Films Using Novel Single Source Precursors  [PDF]

Materials Sciences and Applications (MSA) , 2017, DOI: 10.4236/msa.2017.810052
Abstract: Polycrystalline thin films of ZnSe and ZnSxSe1-x have been deposited on glass substrates by Aerosol Assisted Chemical Vapour Deposition (AACVD) from bis(diethyldiselenocarbamato)zinc(II) and a 1:1 and 1:0.75 mixtures of bis(diethyldiselenocarbamato)zinc(II) and bis(diethyldithiocarbamato)zinc(II) as precursors. All films were characterized by p-XRD, SEM, EDX, Raman spectroscopy, photoluminescence (PL and UV/Vis spectroscopy. The band gap of pure ZnSe thin films was found to be 2.25 whereas the band gap of ZnSxSe1-x films varied from 2.55 to 2.66 eV depending on the sulfur content in the films. PL emission spectra showed a clear blue shift for ZnSxSe1-x films compared to ZnSe due to the sulphur content in the films which increase the band gap. The band gap of ZnSSe can be controlled by sulfur to selenium ratio in the alloy. The morphology of the ZnSe thin films changed from small randomly shaped crystallites to triangles whereas the morphology of ZnSxSe1-x was mainly based on cuboids.

World Journal of Nano Science and Engineering (WJNSE) , 2011, DOI: 10.4236/wjnse.2011.14016
Abstract: The nano ceramic Ba0.5Sr0.5Co0.2Fe0.8O3 (BSCF) powders have been synthesized by Sol-Gel process using nitrate based chemicals for SOFC applications since these powders are considered to be more promising cathode materials for SOFC. Glycine was used as a chelant agent and ethylene glycol as a dispersant. The powders were calcined at 850℃/3 hr in the air using Thermolyne 47,900 furnace. These powders were characterized by employing SEM/EDS, XRD and TGA/DTA techniques. The SEM images BSCF powder indicate the presence of highly porous spherical particles with nano sizes. The XRD results shows the formation of BSCF perovskite phase at the calcination temperature of 850℃. From XRD line broadening technique, the average crystllite size of the BSCF powders were found to be around 9.15 - 11.83 nm and 13.63 - 17.47 nm for as prepared and after calcination at 850℃ respectively. The TGA plot shows that there is no weight loss after the temperature around 450℃ indicating completion of combustion.

Open Journal of Applied Sciences (OJAppS) , 2014, DOI: 10.4236/ojapps.2014.46035
Abstract: The ignored curriculum is one of important elements in the curriculum that the design of this concept has led to reduce a superficial look at measures to curriculum. Ignored curriculum not only in the design but also should be considered at the implementation level. The present study examined the experiences of teachers in general education from ignored curriculum in higher education and this study was done by qualitative research and its approach was interpretive phenomenology. In this regard, semi-structured interviews were conducted with twenty-six teachers of general education courses and the data obtained from these interviews were analyzed by using phenomenology of Smith. Three major themes from ignored curriculum, were found from the experience of teachers including 1) lack of attention to requirements which consists of three sub-categories: in attention to the needs of the learner, the needs and demands of everyday life and the needs of experts; 2) lack of attention to content; 3) run into problems involving the four sub-problems of teaching, evaluation time, space and assessment. The teachers during the training and implementing courses have gained a lot of experience from the ignored curriculum that had impact on their perception. Planners are familiar with academics experiences and identify ignored curriculum of general education courses and emphasized on how they understand the main goals of general education courses and made it meaningful and they had a main role in eliminating the flaws of this course, and enhance the effectiveness of them. In summary, the results obtained from the study were that general education courses, do not address the needs of learners. These requirements include of three sub-categories: inattention to the needs of the learner, routine needs and professionals. Also, courses have less attention to content. And there are problems such as difficulties in teaching this lesson, time, space and evaluation.

Int'l J. of Communications, Network and System Sciences (IJCNS) , 2016, DOI: 10.4236/ijcns.2016.99032
Abstract: The aim of this research is to explore the relationship between corporate social responsibility, employee engagement, and organizational performance in Jordanian mobile telecommunication companies. A total of 350 questionnaires containing 37 items?were used to collect information from the respondents. Multiple and simple regression analyses were conducted to test the research hypotheses. Results of the current study revealed that corporate social responsibility (both internal and external) and employee engagement (vigor, absorption, and dedication) have a significant positive relationship with organizational performance. Also, the results revealed that there is a significant positive relationship between corporate social responsibility (internal CSR and external CSR) and employee engagement. The Baron and Kenny mediation model and Sobel test were used to test whether employee engagement mediated the relationship between corporate social responsibility and organizational performance. The results showed that employee engagement fully mediated the relationship in a significant way. The results of the current study have many managerial implications for mobile telecommunication companies. In order to enhance organizational performance, decision makers must work on creating and maintaining an efficient corporate social responsibility agenda, which would increase employees’ engagement in their work which will lead to improved performance outcomes.

Int'l J. of Communications, Network and System Sciences (IJCNS) , 2016, DOI: 10.4236/ijcns.2016.911039
Abstract: Survival in today’s dynamic environment requires organizations to have superior performance compared to competitors. In order to achieve this superior performance, this study aimed to examine the effect of both strategic orientation and innovation on organizational performance. It also examined whether innovation acted as a mediator between strategic orientation and organizational performance. Data were gathered from the three telecommunication companies that exist in Jordan. The data were then analysed using Structural Equation Modelling (SEM) and the results revealed that strategic orientation had a significant effect on innovation but not on organizational performance. It was also found that innovation significantly affected organizational performance. Finally, the results indicated that innovation mediated the path between strategic orientation and organizational performance, but only partially.

Ebtesam A. Yousef
Open Journal of Marine Science (OJMS) , 2017, DOI: 10.4236/ojms.2018.81004
Abstract:
A total 5849 individuals of ostracods constituting twenty species were collected from five shallow marine sites along the area from El-Quseir to Marsa Alam on the West Coast of the Red Sea. The twenty ostracod species belonging to sixteen genera and ten different families. The three genera; Loxoconcha, Neonesidea and Xestoleberis have high species diversity. Furthermore, the species Loxoconcha ghardaqensis, Xestoleberis rotunda, Paranesidea fracticorallicola, Tanella gracilis and Neonesidea schulzi were the best recognized in the collecting region. Otherwise, the distribution of the collected ostracod species in relation to environmental variables and plants were discussed in detail here. Based on this, it is concluded that, vegetation type appears to be the most important factor controlling the distribution of ostracod species in the investigated area. Also, other factors such as, water temperature, salinity, dissolved oxygen, pH and electrical conductivity play an important role. Scanning electron microscope images of valves are delivered of the recorded taxa. These fauna displays close affinities to those of the Red Sea and the Indo- Pacific region.
