Zahid Javed,Ahsan Raza Sattar,Tasleem Mustafa,Muhammad Shakeel Faridi
International Journal of Computer Science Issues , 2012,
Abstract: Under development countries (UDCs) like Faisalabad, Pakistan where information technology benefits are not yet fully utilized due to lack of resources and very old infrastructure. Selecting suitable commercial off-the-shelf (COTS) is the most critical phase in COTS-based software development. However, in research, numerous problems are faced during the COTS evaluation, selection and integration. All these major causes are due to the lack of familiarity about COTS products, the unawareness of the available number of methods for COTS evaluation, selection, integration and deployment phase, and the deficiency of supervision for selecting between these best methods for COTS evaluation and selection. In this research work, a closed questionnaire method was adopted to evaluate the users perception about COTS evaluation, selection integration in software houses and IT Professional in Faisalabad, Pakistan. The results of this work will contribute towards a framework development for COTS evaluating and selecting, integration.

Merlin Thomas, Wanis H. Ibrahim, Tasleem Raza, Kamran Mushtaq, Adeel Arshad, Mushtaq Ahmed, Salma Taha, Shireen Omer, Saber Al Sarafandi, Omer Rabadi, Hisham A. Abdul-Sattar
Journal of Tuberculosis Research (JTR) , 2018, DOI: 10.4236/jtr.2018.64024
Abstract: Background: Distinguishing tuberculous pleural effusion (TPE) from other causes of exudative effusion is often challenging. Delay in treatment initiation can occur while awaiting histo-microbiologic confirmation owing to the paucibacillary nature of the disease. Sago-like nodules are the most common visual finding on gross thoracoscopic appearance. The primary objective was to determine the diagnostic utility of the presence of sago-like nodules on gross thoracoscopic appearance in TPE to help justify early initiation of tuberculosis (TB) treatment based on their finding while awaiting final histo-microbiologic confirmation. Secondary objective was to study the correlation between the presence of sago-like nodules and the final histo-microbiologic findings in pleural biopsy specimens. Methods: This was a retrospective-descriptive study of all patients with exudative pleural effusion who underwent diagnostic medical thoracoscopy (MT) at Hamad General Hospital during an eight-year period (from January, 2008 to December, 2015). Results: The presence of sago-like nodules on gross thoracoscopic appearance of the pleural surface had a sensitivity of 58%, a specificity of 89% and a positive predictive value of 97% for TPE with a diagnostic accuracy of 62%. There is significant association between the presence of sago-like nodules and demonstration of granulomatous inflammation in pleural biopsy specimens (P = 0.000). There is no association between sago-like nodules and positive TB smear and culture in biopsy specimens. Conclusion: The presence of sago-like nodules on gross thoracoscopic appearance has a high specificity and positive predictive value for TPE and significantly correlates with the presence of granulomatous inflammation. Patients from TB prevalent areas with exudative pleural effusion and sago-like nodules on gross thoracoscopic appearance may be commenced on TB chemotherapy while awaiting final histologic confirmation.

Case Reports in Medicine , 2013, DOI: 10.1155/2013/745714
Abstract: Aspirin-exacerbated respiratory disease (AERD) is a well-known clinical condition. Aspirin desensitization followed by daily aspirin therapy is the treatment of choice. We report a challenging case of primary cutaneous vasculitis following aspirin desensitization in a patient with AERD. The vasculitis was likely suppressed with higher dose systemic steroid use to control asthma. Aspirin desensitization led to improved asthma control and steroid reduction, which led to manifestation of prior suppressed cutaneous vasculitis. In our case, there was no evidence of systemic involvement and the patient had a favorable outcome with appropriate therapy. 1. Introduction Aspirin desensitization is one therapeutic modality for patients with aspirin-exacerbated respiratory Disease (AERD). It may precipitate multiple side effects including cutaneous vasculitis (CV) [1, 2]. CV may be primary in nature or secondary to other multiple underlying disorders such as systemic necrotizing vasculitis, connective tissue diseases, infections, or malignancies [3]. Drug induced cutaneous vasculitis (DIV) has been reported secondary to nonsteroidal anti-inflammatory drugs (NSAIDs) [4]. Here we report a challenging case of primary cutaneous vasculitis following aspirin (ASA) desensitization in a patient with AERD. Previous reports found a relation between autoimmune vasculitis and aspirin-induced asthma (AIA) [5, 6]. In our case, there was no systemic involvement. The patient was treated with colchicine and had a favorable outcome. 2. Case Report A 25-year-old gentleman was referred with a difficulty in controling asthma. He had history of chronic rhinosinusitis, recurrent nasal eosinophilic polyps, and two previous polypectomies. Asthma was exacerbated by Ibuprofen in the past. He required two asthma exacerbation related hospital admissions in one year. Examination showed cushingoid feature and steroid related skin changes. Lung exam was significant for diffuse wheezing. No nasal polyps were evident on exam. Other systemic examinations were normal. Erythrocyte sedimentation rate (ESR) was normal. Serum total IgE was 284?KU/L (normal 0–114). Blood eosinophils were 600. Skin prick test was positive for dog and horse hair and spirometry showed moderate reversible obstruction. Chest radiographs showed no abnormalities. His asthma was categorized as moderate to severe with score of 10 on asthma control test (ACT). He was active smoker but managed to quit; however, this did not improve his asthma symptoms. We offered aspirin desensitization. A two-day aspirin (ASA) desensitization

Nonlinear Computational Model of Biological Cell Proliferation and Nutrient Delivery in a Bioreactor  [PDF]
Muhammad Shakeel, Sahar Raza
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.515222

Tissue engineering is a preeminent field which aims to regenerate or repair the functions of devastated or damaged organs or tissues due to some accident, disease or age related degeneration. This field provides immense help in saving lives of thousands of patients. Tissues or organs are engineered within the patient’s body or in a laboratory, which is later implanted in the patient’s body. The important challenges for tissue engineers are: appropriate nutrients supply and optimum cell density with uniform distribution of cells in a final construct. Mathematical modeling is the best tool in order to understand the mechanism of cell proliferation and nutrient supply in a bioreactor. Mathematical models not only help to analyze potentially useful results but also enlighten the way of further research. In this work, a simple mathematical model of diffusive nutrient transport and non-linear cell proliferation in a bioreactor is developed. A cell seeded porous scaffold is kept in a bioreactor with a fixed nutrient supply. We model the consumption and transport of nutrients by reaction-diffusion equation and cell proliferation by Fisher Kolmogorove equation. Nutrient delivery to the cell seeded scaffold is purely due to diffusion. The model is solved numerically by commercial finite element solver COMSOL. The results show that all types of constructs, if nutrient supply depends on diffusion, will produce cell proliferated regions near nutrient supply. The results are presented for uniform and non-uniform initial cell seeding strategies. It is also observed that cell proliferation is insensitive to the initial seeding strategy.

Journal of Computer and Communications (JCC) , 2015, DOI: 10.4236/jcc.2015.310006
Abstract: Online Education (OE) system is an effective and efficient way to perform the education in all sectors of government and non-government educational organization. Low performance and minimum speed are major overhead in the current ongoing OE system due to the increase of users and some system issues. Base on the previous study and recent practical issues, a model is proposed to Enhancing the Performance of Online Education System (EPOES) to examine the bare metal virtualization, isolation and virtual machine templates. Bare metal virtualization has led the native execution, isolation isolated the running application and Virtual Machine Template has help to increase efficiency, avoiding the repetitive installation and operate the server in less time. The proposed model boosts the performance of the current OE system, and examines the benefits of the adaptation of cloud computing and virtualization which can be used to overcome the existing challenges and barriers of the current OE System.
Esext3 for Reducing the Effect of Harboring Bug in File System  [PDF]
Raza Muhammad, Basheer Riskhan
Journal of Software Engineering and Applications (JSEA) , 2017, DOI: 10.4236/jsea.2017.104021
Abstract: One of the most critical threats to the reliability and robustness for file system is harboring bug (silent data corruption). In this research we focus on checksum mismatch since it occurs not only in the user data but also in file system. Our proposed solution has the ability to check this bug in file system of Linux. In our proposed solution there is no need to invoke or revoke checker utility, it comes as the integrated part of file system and has the ability to check upcoming updates before harboring bug make unrecoverable changes that leads significant data loses. Demonstration testing shows satisfactory results in file server and web server environments in terms of less memory consumption and avoidable delay in system’s updating.

Open Access Library Journal (OALib Journal) , 2014, DOI: 10.4236/oalib.1100487

Bell’s palsy is an acute disorder of the facial nerve in which full or partial loss of the movement on one side of face occurs. The Bell’s palsy gets better without treatment in most, but not all, people. Swelling or inflammation of this nerve can also cause Bell’s palsy. Physical therapies exercise, massage, laser, electrotherapy and thermotherapy used to hasten recovery. Many people who have a Bell’s palsy at first think that they have a stroke. Bell’s palsy is very different to a stroke and full recovery occurs in most cases. People are not aware about this disease therefore we have conduct survey regarding Bell’s palsy, their sign symptoms and treatment in students of pharmacy, science and arts faculties. It is observed that out of 120 students’ only 61.67% students have known about Bell’s palsy. Only 26.67% know the causes, 46.67% know the sings & symptoms on behave of animals & only 33.3% have some knowledge about treatments based mostly on home remedies. It is concluded that the knowledge of Bell’s palsy in students is not enough to dial uncertain mishap pining of the disease & the must aware to the disease to treat other more better otherwise they will not cover fully to this disease.

Non-equilibrium Green's function based single-band tight-binding model for Fe-MgO-Fe magnetic tunnel junction devices
Tehseen Raza,Hassan Raza
Physics , 2008,
Abstract: Motivated by observation of very high tunnel magnetoresistance (TMR) in Fe-MgO-Fe magnetic tunnel junction devices, we propose a theoretical model for these devices based on a single-band tight-binding approximation. An effort is made to capture the band dispersions over the two dimensional transverse Brillouin zone. In the transport direction, spin dependent Hamiltonian is prescribed for Delta_1 and Delta_5 bands. Non-equilibrium Green's function formalism is then used to calculate transport. Features like voltage dependence of TMR are captured quantitatively within this simple model and the trends match well with the ones predicted by ab-initio methods and experiments.
Applications of Quantum Physics on Resistivity, Dielectricity, Giant Magneto Resistance, Hall Effect and Conductance  [PDF]
Saleem Iqbal, Farhana Sarwar, Syed Masood Raza, Syed Mohsin Raza
World Journal of Condensed Matter Physics (WJCMP) , 2016, DOI: 10.4236/wjcmp.2016.62013
Abstract: Quantum theory with conjecture of fractional charge quantization, eigenfunctions for fractional charge quantization, fractional Fourier transform, Hermite function for fractional charge quantization, and eigenfunction for a twisted and twigged electron quanta is developed and applied to resistivity, dielectricity, giant magneto resistance, Hall effect and conductance. Our theoretical relationship for quantum measurements is in good conformity and in agreement with most of the experimental results. These relationships will pave a new approach to quantum physics for deciphering measurements on single quantum particles without destroying them. Our results are in agreement with 2012 Physics Nobel Prize winning Scientists, Serge Haroche and David J. Wineland.
