CHARACTERISTICS OF PATIENTS HOSPITALIZED WITH 2009 H1N1 INFLUENZA IN A TERTIARY CARE HOSPITAL IN SOUTHERN SAUDI ARABIA
Adnan Agha,Abdul Qader Alrawi,Abdelhaleem Bella,Mohammed S. AlAyed
Mediterranean Journal of Hematology and Infectious Diseases , 2012, DOI: 10.4084/mjhid.2012.
Abstract: Background Pandemic influenza A (H1N1) virus emerged and spread globally in the spring of 2009. We describe the clinical features of the patients who were hospitalized with 2009 H1N1 influenza July 2009 to June 2010 in a tertiary care hospital in Khamis Mushyt, Saudi Arabia. We analyzed the clinical and laboratory variables in order to determine predictors of poor outcome Methods We performed a prospective study in all patients who were hospitalized for at least 48 hours and with a positive test for 2009 H1N1 virus through RT-PCR(real time polymerase chain reaction). Their epidemiological, clinical, biochemical characteristics were collected and the hospital course of the patients with eventual outcome (discharge or death) was observed. We applied a logistic regression analysis to determine the best predictor of death.

Open Journal of Preventive Medicine (OJPM) , 2013, DOI: 10.4236/ojpm.2013.37059
Abstract: Background: Ageing of the population is one of the most important demographic facts that come to the foreground in the 21st century. Objective: To assess the relationship between psychological factors (depression, loneliness, using anti anxiety medication, fear from falls and internal displacement of the population) and falls among elderly people in Baghdad city, Iraq. Methods: A matched 1:1 community based case-control study involving 716 elderly respondents, recruited randomly from six Non Governmental Organization (NGO) in different areas of Baghdad. Interviews to each respondent were done accordingly. Geriatric depression scale (GDS) was used to assess the depression among the elderly people. Results: The minimum age for cases and controls was 60 years old while the maximum age for cases was 87 and for controls was 85 years old. The female was predominant than male, 53.6% to 46.4% respectively. The relation between depression, fear from fall, using anti anxiety medication, internal displacement and falls was statistically significant (p < 0.001). Conclusions: Psychological factor especially depression among elderly people is one of the important risk factors contributing to falls accident. Fear from falls, displacement and taking anti anxiety medication were also in significant relation.

 

Improved Shear Performance of Bent-Up Bars in Reinforced Concrete Beams .
Abdul Qader S. Najmi,Moayyad M. Al-Nasra,Naiem M. Asha
International Journal of Engineering Sciences & Research Technology , 2013,
Abstract: Shear failure of reinforced concrete beams is often sudden and catastrophic. This sudden failure, due to shear, made it necessary to explore more effective ways to design reinforced concrete beam for shear. The reinforced concrete beams show different behavior at the failure stage in shear compare to the bending, which is considered to be unsafe mode of failure. The shear cracks progressive rapidly without sufficient advanced warning, and the diagonal cracks that develop due to excess shear forces are considerably wider than the flexural cracks. The cost and safety of shear reinforcement in reinforced concrete beams led to the study of other alternatives. Bent-up bars have been used in the past. New form of bent-up bars will be used. Cross bars will be welded to these bent-up bars making rectangles capable of resisting shear in a plane compared to single bar performance. The main purpose is to identify the most efficient shape to carry shear forces at the lowest cost. Several reinforced concrete beams were carefully prepared and tested in the lab. The results of these tests will be presented and discussed. The deflection of each beam is also measure at a given applied load. The propagation of shear cracks was also closely monitored.
An Overview of Laser Principle, Laser-Tissue Interaction Mechanisms and Laser Safety Precautions for Medical Laser Users
Mohammed M. Jawad,Sarah T. Abdul Qader,A.A. Zaidan,B.B. Zaidan
International Journal of Pharmacology , 2011,
Abstract: Laser can now be regarded as practical and economical tool with unique properties that has been utilized effectively in several applications. Medical, dental, biological and various chemical and physical investigations use lasers due to their advantages. The medical laser systems offer the physician and the dentist not only a window, but also a door into this high technology which facilitate a lot of clinical and therapeutic applications. The user of the medical laser should understand the fact that there is no certain laser can be used for all tasks, therefore, it is important for the medical laser users to have a fundamental understanding of qualitative laser technology and essential operation of those lasers with biological tissues. In spite of their advantages, lasers have definite hazard by causing serious damage on the tissue of both patient and laser operation personnel. Due to this fact, laser users should study the laser hazards and safety precautions.
Review Article: The Role of Nitric Oxide Synthase in Post-Operative Hyperglycaemia
SS Qader
Libyan Journal of Medicine , 2008,
Abstract: Post-operative hyperglycaemia is important with regard to outcomes of surgical operations. It affects post-operative morbidity, length of hospital stay, and mortality. Poor peri-operative blood glucose control leads to a higher risk of post-operative complication. Insulin resistance as a cause of postoperative hyperglycaemia has been blamed for some time. Nitric Oxide (NO) is produced by nitric oxide synthase (NOS) isoenzymes. Inducible nitric oxide synthase (iNOS) is not a normal cellular constitute. It is expressed by cytokines and non-cytokines e.g. fasting, trauma, intravenous glucose, and lipid infusion, which are encountered in surgical operations. Review of current published data on postoperative hyperglycaemia was completed. Our studies and others were explored for the possible role of NO in this scenario. Induction and expression of iNOS enzyme in pancreatic islet cells is included in the chaotic postoperative blood glucose control. The high concentrations of iNOS derived NO are toxic to pancreatic β-cells and may inhibit insulin secretion postoperatively. Hence, current peri-operative management is questionable regarding post-operative hyperglycaemia and necessitates development of a new strategy.
Unveiling Zeus

Computer Science , 2013,
Abstract: Malware family classification is an age old problem that many Anti-Virus (AV) companies have tackled. There are two common techniques used for classification, signature based and behavior based. Signature based classification uses a common sequence of bytes that appears in the binary code to identify and detect a family of malware. Behavior based classification uses artifacts created by malware during execution for identification. In this paper we report on a unique dataset we obtained from our operations and classified using several machine learning techniques using the behavior-based approach. Our main class of malware we are interested in classifying is the popular Zeus malware. For its classification we identify 65 features that are unique and robust for identifying malware families. We show that artifacts like file system, registry, and network features can be used to identify distinct malware families with high accuracy---in some cases as high as 95%.
On Wavelet Transform General Modulus Maxima Metric for Singularity Classification in Mammograms  [PDF]
Tomislav Bujanovic, Ikhlas Abdel-Qader
Open Journal of Medical Imaging (OJMI) , 2013, DOI: 10.4236/ojmi.2013.31004
Abstract: Continuous wavelet transform is employed to detect singularities in 2-D signals by tracking modulus maxima along maxima lines and particularly applied to microcalcification detection in mammograms. The microcalcifications are modeled as smoothed positive impulse functions. Other target property detection can be performed by adjusting its mathematical model. In this application, the general modulus maximum and its scale of each singular point are detected and statistically analyzed locally in its neighborhood. The diagnosed microcalcification cluster results are compared with health tissue results, showing that general modulus maxima can serve as a suspicious spot detection tool with the detection performance no significantly sensitive to the breast tissue background properties. Performed fractal analysis of selected singularities supports the statistical findings. It is important to select the suitable computation parameters-thresholds of magnitude, argument and frequency range-in accordance to mathematical description of the target property as well as spatial and numerical resolution of the analyzed signal. The tests are performed on a set of images with empirically selected parameters for 200 μm/pixel spatial and 8 bits/pixel numerical resolution, appropriate for detection of the suspicious spots in a mammogram. The results show that the magnitude of a singularity general maximum can play a significant role in the detection of microcalcification, while zooming into a cluster in image finer spatial resolution both magnitude of general maximum and the spatial distribution of the selected set of singularities may lead to the breast abnormality characterization.
Electricity Consumption and GHG Emissions in GCC Countries
Mohammed Redha Qader
Energies , 2009, DOI: 10.3390/en20401201
Abstract: CO 2, N 2O, and CH 4 are the three most widespread Greenhouse Gases (GHGs). Electricity consumption and the related CO 2-equivalent gas emissions resulting from oil and gas combustion for the six countries that comprise the Cooperation Council for the Arab States of the Gulf [Kingdom of Saudi Arabia (KSA), Kuwait, Bahrain, Oman, United Arab Emirates (UAE) and Qatar; also referred to as the Gulf Cooperation Council, GCC)] have been compared. The analysis of the relevant data shows that GCC countries contribute significantly to the global CO 2 emissions, and that the majority of their emissions are concentrated in the energy extraction and conversion sectors, mainly from oil drilling and electricity production. Some analysis is offered as to the reasons behind the excessive increase in the electrical demand that is obviously linked to a non-rational pattern of electricity consumption.
Is Global Warming Likely to Cause an Increased Incidence of Malaria?
SA Nabi, SS Qader
Libyan Journal of Medicine , 2009,
Abstract: The rise in the average temperature of earth has been described as global warming which is mainly attributed to the increasing phenomenon of the greenhouse effect. It is believed that global warming can have several harmful effects on human health, both directly and indirectly. Since malaria is greatly influenced by climatic conditions because of its direct relationship with the mosquito population, it is widely assumed that its incidence is likely to increase in a future warmer world. This review article discusses the two contradictory views regarding the association of global warming with an increased incidence of malaria. On one hand, there are many who believe that there is a strong association between the recent increase in malaria incidence and global warming. They predict that as global warming continues, malaria is set to spread in locations where previously it was limited, due to cooler climate. On the other hand, several theories have been put forward which are quite contrary to this prediction. There are multiple other factors which are accountable for the recent upsurge of malaria: for example drug resistance, mosquito control programs, public health facilities, and living standards.
