Alternatives Strategies to Empower Youth Volunteering in Omani Society Using SWOTAnalysis Technique
The study aimed to develop strategic alternatives to activate volunteer work among Omani youth. SWOT analysis was used to indicate the strength, weaknesses, opportunities and challenges faced by youth. A questionnaire of 32 items with two domains was developed. An estimation of reliability using Cronbach-Alpha indicated 0.887 for level of effectiveness, and 0.918 for level of existences. A sample of 89 experts from civil society organizations and higher education institutions from different Omani governorates was selected. The results revealed that the most powerful aspects of volunteering were the incentives to encourage youth, notably the Sultan Qaboos Award for Volunteerings at the national level, and the existence of many charities, including those related to women associations, and others that provide voluntarily services to special needs people. The overall average weight of the strengths and weaknesses was 194.44 and 186.46 respectively. The main opportunities were reflected by existing governmental departments to follow up the work of the voluntary institutions, and the NGO civil societies’ global awareness of volunteering. Further, the study results showed that average percentage means of opportunities and challenges were 145.04 and 143.79 respectively. Considering these results, four strategic alternatives were developed
ZCT 313/2 - OPTIK OKT-NOV 1996.
We report the instantaneous decomposition of the small molecular gold cluster, Au25SG18 (SG-glutathione thiolate) in the presence of externally added chloroaurate ions resulting in the instantaneous formation of the insoluble gold-glutathione polymer. The rate of decomposition, however, was much slower for the metal ions such as Ag+, Fe3+, Cu2+, Ni2+, Cd2+, Zn2+ and Sr2+. This chemical reactivity is shown to have no direct correlation with the electrochemical potential of the added ions
Specialty selection satisfaction and regret among medical school postgraduates and faculty at King Abdulaziz University
Background: In the field of medicine, specialty selection is a life-altering decision that plays a crucial role in career satisfaction, and in turn patient-care. This study explores the significant factors affecting specialty selection satisfaction and regret from the perspective of medical postgraduates and faculty in King Abdulaziz University (KAU). Methods: A cross sectional study was carried out on a sample of 172 medical school postgraduates and faculty working at KAU using self-administered questionnaire.Results: The majority of the participants were residents (51.7%), The analysis showed that 11% of the participants regret their choice of specialty. The results showed that the level of satisfaction increases as the academic degree of the participants increase. Among the significant factors affected specialty selection satisfaction and regret were; income (P = 0.003), long length of training (P = 0.027), vast options of sub-specialties (P = 0.001) and interesting and exciting field.Conclusion: These results identify the essential factors that have a potential impact on specialty satisfaction and regret among medical school postgraduates and faculty. This highlights the importance of career counseling for the proper specialty selection
Comparison of automated versus traditional nerve conduction study methods for median nerve testing in a general worker population
OBJECTIVE: To investigate the validity of automated nerve conduction studies compared to traditional electrodiagnostic studies (EDS) for testing median nerve abnormalities in a working population. DESIGN: Agreement study and sensitivity investigation from two devices SETTING: Field research testing lab PARTICIPANTS: Active workers from several industries participating in a longitudinal study of CTS. METHODS: Sixty-two subjects received bilateral median and ulnar nerve conduction testing across the wrist with a traditional device and the NC-stat automated device. We compared intermethod agreement of analogous measurements. MAIN OUTCOME MEASUREMENT: Nerve conduction study parameters RESULTS: Median motor and sensory latency comparisons showed excellent agreement (intra-class correlation 0.85 and 0.80 respectively). Areas under the receiver operator characteristic curves were 0.97 and 0.96 respectively, using the optimal thresholds of 4.4ms median motor latency (sensitivity 100%, specificity 86%) and 3.9ms median sensory latency (sensitivity 100%, specificity 87%). Ulnar nerve testing results were less favorable. CONCLUSION: The automated NC-stat device showed excellent agreement with traditional EDS for detecting median nerve conduction abnormalities in a general population of workers, suggesting that this automated nerve conduction device can be used to ascertain research case definitions of CTS in population health studies. Further study is needed to determine optimal thresholds for defining median conduction abnormalities in populations that are not seeking clinical care
Assessment of Selected Heavy Metal Content on Dumpsites Soil and Vegetables Grown in Muwo Metropolis, Niger State, Nigeria
This study examines the concentration of heavy metals in soil samples and some vegetables (spinach, water leaf, bitter leaf and jute mallow) cultivated around dumpsites in Muwo Metropolis, Niger State, Nigeria. The soil samples and vegetable were analyzed for Ni, Zn, Cu, Pb and Cd using AA500 spectrophotometer after acid digestion. Data obtained show that, the Pb (1.684 mg/kg of Jute) content was high compared to other metals study in this work. Concentration of Zn was 1.993, 0.862 and 0.443 mg/kg for water leaf, soil and control sample respectively. The content of Pb was 1.727, 1.738 and ND mg/kg for water leaf, soil and control sample respectively. Also, the concentration of Pb was 1.736, ND and 0.457 mg/kg for spinach, soil and control sample respectively. However, the content of Zn was 0.786, 0.751 and 0.554 mg/kg for spinach, soil and control sample respectively The accumulation of heavy metals in agricultural soils is of increasing concern because of, potential health risks, food safety as well as its detrimental effects on the soil ecosystem and human health. The pollution indexes of Ni contents are 0.439, 0.378, and 0.083 for jute, soil and control sample respectively. While Zn concentration was 1.117, 0.858 and 0.492 for jute, soil and control sample respectively. The result of this study shows that Pb concentrations are present in high levels in the study area at the different level of contamination
Constraints on scalar-pseudoscalar and tensorial nonstandard interactions and tensorial unparticle couplings from neutrino-electron scattering
Neutrino-electron scattering is a purely leptonic fundamental interaction and therefore provides an important channel to test the Standard Model, especially at the low energy-momentum transfer regime. We derived constraints on neutrino nonstardard interaction couplings depending on model-independent approaches which are described by a four-Fermi pointlike interaction and the unparticle physics model with tensorial components. Data on (nu) over bar (e) - e and nu(e) - e scattering from the TEXONO and LSND experiments, respectively, are used. The upper limits and the allowed regions of scalar, pseudoscalar, and tensorial nonstandard interaction couplings of neutrinos are derived at 90% confidence level in both one-parameter and two-parameter analysis. New upper limits for tensorial unparticle physics coupling constants and mass parameters are also placed
Energy efficiency in residential buildings using nano-wood composite materials
Wood is one of the conventional building materials in the world, due to its availability and sustainability in nature. The electric and thermal conductivity of wood have made it exceptional among the other conventional construction materials. Nevertheless, wood has deficiencies such as deterioration as a result of fungal and insect attack, vulnerability to fire and dimensional variability to water absorption. Nanotechnology has been in use in other scientific and technological fields for long period of time, but it is still fresh to some extent in architecture. When nanotechnology is applied to the conventional wood, a nono-wood composite will be produce with enhanced properties such as mechanical strength, fire resistance, durability, water immersion. This paper is aimed at examining how wood as a conventional building material can be enhanced using nanotechnology. It further consıders the conservation of energy in residential buildings through the building integrated nano-wood technology
Use of Information and Communication Technologies among Extension Agents In Kano State, Nigeria
The study assessed the use of ICTs among extension agents in Kano State Nigeria. Two hundred and twenty-one (221) extension agents were randomly selected from the 44 local government areas. Data for the study were obtained with the aid of structured questionnaire administered to extension agents. Majority of extension agents were in the age range of 41-50 years. Majority (87.3%) of them were males and married (100%), with family sizes of 5-14 (53.95%). The entire extension agents had formal education including HND (35.8%), OND (33.3%) and secondary school certificate (27.2%). Most of the extension agents had an annual income of N100,000- N300,000, with N376,984 as mean. They were aware and had access to radio, television, telephone, DVD, video, camera, computer, satellite and printer. They however recorded a low usage of the Web, satellite, e-mail, CD-ROM, search engines, scanner, fax and Web publishing. The result also indicates a positive correlation between ICT use and socio-economic characteristics of the agents; including age, work experience, membership of agricultural associations (p<0.05). It was concluded that the benefits of the ICTs were not fully utilized by extension
