Examining the Value of Money in England over the Long Term (1259-2009)
Adam Abdullah
International Journal of Economics and Finance , 2013, DOI: 10.5539/ijef.v5n3p73
Abstract: This paper seeks to analyze the value and purchasing power of money in England over 750 years, during which time the pound has lost almost all of its value. This paper proposes a suitable methodology of measuring nominal inflation in England over the long term, by constructing a wholesale commodity price index in order to determine the purchasing power of money, being the inverse of prices. The index adjusts indices of the value of gold and silver, to determine the purchasing power of gold, silver, and also real prices, thereby providing a suitable technique to measure the store of value function of money. In so doing, we discover that a monetary theory of value accurately interprets the empirical evidence.
The Gibson Paradox: Real Gold, Interest Rates and Prices
Adam Abdullah
International Business Research , 2013, DOI: 10.5539/ibr.v6n4p32
Abstract: This paper aims to provide an analysis and explanation of the curious empirical relationships that exist between the price of gold, the interest rate and commodity prices, operating under the English 19th century fractional reserve gold standard and the modern American fractional reserve fiat paper standard, known as the Gibson Paradox. This paper argues that the value and purchasing power of the British pound and American dollar are managed in relation to their rate of exchange with gold and the real rate of interest, such that, changes in the general level of prices are the effect and not the cause.

Abstract: rmacist-documented interventions during the dispensing process in a primary health care facility in Qatar Original Research (5309) Total Article Views Authors: Richard Hooper, Abdullah Adam, Nadir Kheir Published Date November 2009 Volume 2009:1 Pages 73 - 80 DOI: http://dx.doi.org/10.2147/DHPS.S5534 Richard Hooper1, Abdullah Adam2, Nadir Kheir3 1Medical Services Department, 2Pharmacy Department, Medical Services, Qatar Petroleum, Doha, Qatar; 3Qatar University, College of Pharmacy, Doha, Qatar Objectives: To characterize prescribing error interventions documented by pharmacists in four pharmacies in a primary health care service in Qatar. Methods: The study was conducted in a primary health care service in the State of Qatar in the period from January to March 2008. Pharmacists in four clinics within the service used online, integrated health care software to document all clinical interventions made. Documented information included: patient’s age and gender, drug therapy details, the intervention’s details, its category, and its outcome. Interventions were categorized according to the Pharmaceutical Care Network Europe Classification of drug-related problems (DRP). Results: The number of patients who had their prescriptions intercepted were 589 (0.71% of the total 82,800 prescriptions received). The intercepted prescriptions generated 890 DRP-related interventions (an average of 1.9% DRPs identified across the four clinics). Fifty-four percent of all interventions were classified as drug choice problems, and 42% had safety problems (dose too high, potential significant interaction). The prescriber accepted the intervention in 53% of all interventions, and the treatment was changed accordingly. Interventions as a result of transcription errors, legality and formulary issues were eliminated from this study through the use of computerized physician order entry (CPOE). Conclusions: Documenting and analyzing interventions should be a routine activity in pharmacy practice setting in primary health care services. Educational outreach visits and other strategies can improve prescribing practices and enhance patient safety.

Investigating “Egusi” (Citrullus Colocynthis L.) Seed Oil as Potential Biodiesel Feedstock

Energies , 2010, DOI: 10.3390/en3040607
Abstract: Biodiesel’s acceptance as a substitute for fossil-derived diesel has grown the world over. However, the food-fuel debate over conventional vegetable oils has rekindled research interest in exploring lesser known and minor oil crops. In this work, egusi melon seed oil was studied for the first time as a potential feedstock for biodiesel production. Crude egusi melon seed oil was transesterified using sodium methoxide as the catalyst at 60 °C and an oil/methanol ratio of 1:6 to produce its corresponding methyl esters. Egusi melon oil methyl ester (EMOME) yield was 82%. Gas chromatographic analysis of EMOME showed that it was composed mainly of palmitic, stearic, oleic, linoleic and linolenic esters, which is similar to the profile of sunflower, soybean and safflower oil. All the measured fuel properties of EMOME satisfied both the ASTM D6751 and the EN 14214 biodiesel standards. Fuel properties of EMOME were essentially identical with those of soybean, safflower and sunflower biodiesel. Remarkably, the kinematic viscosity of EMOME was measured to be 3.83 mm 2/s, a value lower than most biodiesel fuels reported in the literature. The potential of egusi melon seed oil as a biodiesel feedstock is clearly presented in this study.

PIER B , 2009, DOI: 10.2528/PIERB09061601
Abstract: In this paper, a new design of a compact narrowband bandpass filter is proposed. This new narrowband bandpass filter is designed using an octagonal form of dual-mode closed-loop microstrip ring resonator based on a meander structure in order to achieve compactness. The designed filter has a 3 dB fractional bandwidth (FBW) of 5% at 2.3 GHz. The filter has been fabricated on Taconic CER-10 substrate having 0.64 mm thickness and a relative dielectric constant of 10. Experimental results show good agreement with simulated values. Apart from WiMax, this new model of filter is also useful for WLAN and mobile communication applications, since it is compact in size, low loss, and low cost with good performance of elliptic response with sharp rejection and adequate fractional bandwidth.

Journal of Cancer Therapy (JCT) , 2014, DOI: 10.4236/jct.2014.56059
Abstract:

Objectives: The aim of this study is to detect Epstein-Barr virus (EBV) in nasopharyngeal carcinoma (NPC) biopsies of Sudanese patients using EBV-encoded RNA (EBER) in Situ hybridization (EBER-ISH). Study Design: This is a descriptive cross-sectional study conducted at the National Center for ENT diseases and Head and Neck Surgery and the Institute of Endemic Diseases, University of Khartoum, Khartoum City, Sudan. Subjects and Methods: Biopsies from 43 patients with nasopharyngeal carcinoma were examined for the presence of Epstein-Barr virus using EBER-ISH. Ten normal samples were used to assess the presence of the virus in non cancer tissues. Results: Fifty three samples were examined for the presence of the virus by EBER-ISH, 43 biopsies were NPC and ten were normal. Histologically the cases were, 20 (46.5%), 20 (46.5%) and 3 (7%) of the biopsies were classified as WHO types II, III and mixed type II and III, respectively; there were no cases of type I NPC. All nasopharyngeal carcinoma biopsies (100%) were positive for EBER1 in almost all carcinoma cells with focal and intense dark-blue staining limited to the nucleus; no hybridization was observed in the cytoplasm. No hybridization was observed in all ten non cancer tissues. Conclusion: All NPC cells are clearly EBV-infected. The virus is located in the nucleus of the tumour cells. The presence of Epstein-Barr virus in normal nasopharyngeal epithelia is not a common event. Objectives: The aim of this study is to detect Epstein-Barr virus (EBV) in nasopharyngeal carcinoma (NPC) biopsies of Sudanese patients using EBV-encoded RNA (EBER) in Situ hybridization (EBER-ISH).

Abdullah Alaklabi
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.619305
Abstract: Acacia species are found at various arid and semiarid regions. Among the tree genera of family, Fabaceae, Acacia contains the highest number of species. We have collected different species of Acacia from various places of Saudi Arabia and reconstructed phylogeny for evaluation of genetic relationship among them. Internal transcribed spacer sequence of nrDNA (nrDNA-ITS) locus was used for the reconstruction of phylogeny among these species. Based on phylogenetic tree, Acacia etbaica and A. johnwoodii were close to each other. Similarly, A. ehrenbergiana and A. tortilis were close to each other. Thus, this gene locus was helpful in evaluating the genetic relationship among these species.
Numerical Study of Conjugate Heat Transfer for Cooling the Circuit Board  [PDF]
Abdullah Alrashidi
Journal of Electronics Cooling and Thermal Control (JECTC) , 2016, DOI: 10.4236/jectc.2016.63011
Abstract: In this paper, a 3D model of a flat circuit board with a heat generating electronic chip mounted on it has been studied numerically. The conjugate heat transfer including the conduction in the chip and convection with the surrounding fluid has been investigated numerically. Computational fluid dynamics using the finite volume method has been used for modeling the conjugate heat transfer through the chip and the circuit board. Conjugate heat transfer has broad applications in engineering and industrial applications in design of cooling off electronic components. Effects of various inlet velocities have been studied on the heat transfer variation and temperature of the circuit board. Numerical results show that the temperature of the chip reduces as the velocity of the inlet fluid flow increases.
The Relationship between Size and Performance of Palestinian Water Service Providers  [PDF]
Abdullah Murrar
Journal of Water Resource and Protection (JWARP) , 2017, DOI: 10.4236/jwarp.2017.95035
Abstract: Studies investigating the relationship between size and performance of water service providers are abundant. Yet, this relationship has not been fully addressed in Palestinian water sector, particularly, after the issuance of water law 2014 which calls for merging water providers into large regional utilities. This research evaluates the significant effect of the size of Palestinian water service providers on non-revenue water, staff productivity, collection efficiency, average consumption, average price, operating and maintenance cost, working ratio, and gross profit. The multivariate analysis shows that there are significant differences in working ratio, non-revenue water, staff productivity, average price, and gross profit based on the size. On the other side, no significant differences have been found in average daily consumption, operating and maintenance cost per unit, and collection efficiency based on those providers’ size. The small service providers perform better in non-revenue water, staff productivity, and collection efficiency; wherein, large service providers are more profitable than small service providers. Implications of these findings by conducting further studies will add the value for better merging of the Palestinian water providers and the reforming process.
