Computing Capabilities of Knowledge Workers in the Kuwaiti Health Sector  [PDF]
Sajjad ur Rehman, Abdus Sattar Chaudhry
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103504
Knowledge workers in health care can function well in their clinical and professional practice if they have adequate computing capabilities and they apply them optimally in their work setting. Health information systems (HIS), patient health records (PHR), health databases, health portals, etc. are becoming the essential work-context for these knowledge workers. These professionals have to be equipped with relevant IT competencies in order to be usefully functional, productive and value-driven. HIS was implemented in 2006 in one of the major public hospitals in Kuwait. Thus far the system is partially functional and many of its strengths are not adequately exploited. The Purpose of this study was to examine whether health professionals possess needed computing capabilities and what role did these play in the optimization of the HIS. We conducted a survey administering a questionnaire to a stratified random sample of 210 knowledge workers. We received 130 responses and analyzed data using 124 of the usable responses. In this paper we have reviewed perceptions about the computing capabilities of these professionals, inadequacies they had reported, problems they had encountered, and the role of IT unit in the organization.
Virtual Information Services in Academic Libraries in Kuwait  [PDF]
Sajjad ur Rehman, Aysha M. Al Kandari
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105543
The purpose of this study is to examine the status and prospect of virtual information services in academic libraries in Kuwait. The study conducted open-ended interviews of managers or heads of information services in 12 academic libraries about management and conduct of virtual information service and the possibilities about the future of these ser-vices. Also observed the functioning of services in 9 libraries. It was found that email was the common method for virtual communication in academic libraries in Kuwait. These libraries lacked in services using live chat and mobile application. Social media was mostly used for an-nouncements and marketing of library services. In addition, private aca-demic libraries provided advanced virtual services as compared to public academic libraries. Eight interviews were conducted by phone due to unavoidable circumstances related to both participants and researcher. One private academic institution did not allow access to its library, denying opportunities for observation. This paper provides insights on the way virtual information services were managed and conducted in these libraries. No similar study was noted in this regional context. The findings may help academic library management a better understanding of the issues and challenges they faced and the opportunities they might benefit in future.

Zaeema Islam, Asghar Ali, Irfan Ahmad Baig, Sajjad Ahmad Baig, Muhammad Hashim, Muhammad Zia-Ur-Rehman
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.55072
Abstract: The study investigated the relationship among fiscal deficit, public debt, inflation, international interest rates and the interest rate change in Pakistan using time series data for the period 1981-2011. Augmented Dickey Fuller Unit root test was used to check stationarity of time series data. The study employed co-integration approach to check the long-run relationship among variables. The findings of the study showed a positive and significant relationship between explanatory variables and interest rate change. The study suggested that the fiscal deficit, public debt and double digit inflation should be controlled in order to decrease the interest rate and interest rate fluctuation in Pakistan.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810023871
Abstract: The asymmetric unit of the title compound, C13H13NO3S, contains two crystallographically independent molecules in which the dihedral angles between the phenyl and benzene rings are 88.16 (12) and 44.50 (12)°. One of the molecules features an intramolecular N—H...O hydrogen bond. In the crystal, the molecules are linked into dimers by pairs of N—H...O hydrogen bonds. The dimers are further connected by C—H...O and C—H...π interactions, forming a three-dimensional network.
Evaluation of a Microbiological Growth Inhibition Assay as a Screening Test for the Presence of Antibiotic Residues in Poultry Meat
Muhammad Akbar Shahid,Muhammad Siddique,Sajjad-Ur-Rehman,Sajid Hameed
American Journal of Food Technology , 2007,
Abstract: The present study was conducted to monitor the presence of antibiotic residues in poultry meat. Swab Test on Animal Food (STAF) employing Bacillus subtilis as test organism on nutrient agar with 0.4% dextrose at pH 7, was used. A spore suspension of 2x107 spores mL-1 was used in 100 mL of nutrient agar to make STAF plates. A total of 100 tissue samples (33 liver, 33 kidney and 34 muscles) were collected from local market of Rawalpindi and Islamabad. Thirteen (39.4%) liver, 9 (27.3%) kidney and 7 (20.6%) muscle samples were detected positive for antibiotic residues. Antibiotic sensitivity and Minimum Inhibitory Concentration (MIC) of Oxytetracycline, Gentamicin, Neomycin, Enrofloxacin, Chloramphenicol, Amoxicillin, Benzyl Penicillin, Streptomycin and Tylosin against Bacillus subtilis was determined to be 0.6100, 0.0549, 0.1525, 0.1525, 0.0023, 0.0143, 0.0095, 0.0380 and 0.0023 μg, respectively. It is concluded from the study that STAF test can be used for the preliminary detection of antimicrobial residues in poultry tissues.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0089868
Abstract: This cross-sectional study was carried out to explore the epidemiological and clinical features of dengue fever in Faisalabad, Pakistan during 2011 and 2012. During the study period, anti-dengue IgM positive cases were reported in the post-monsoon period during the months of August–December. Certain hotspots for the dengue infection were identified in the city that coincide with the clusters of densely populated urban regions of the city. Out of total 299 IgM positive patients (male 218 and female 81); there were 239 dengue fever (DF) and 60 dengue hemorrhagic fever (DHF) patients. There was decrease in the median age of dengue patients from 31 years in 2011 to 21.5 years in 2012 (p<0.001). Abdominal pain was seen in 35% DHF patients followed by nausea in 28.3%, epistaxis in 25% and rash in 20% patients (p<0.05). Patients reported to be suffering from high-grade fever for an average of 8.83 days in DHF as compared to 5.82 days in DF before being hospitalized. Co-morbidities were found to be risk factor for the development of DHF in dengue patients. Clinical and laboratory features of dengue cases studied could be used for the early identification of patients at risk of severe dengue fever.
Routing protocols for mobile sensor networks: a comparative study
Shahzad Ali,Sajjad A. Madani,Atta ur Rehman Khan,Imran Ali Khan
Computer Science , 2014,
Abstract: This paper presents a comparison of cluster-based position and non position-based routing protocols for mobile wireless sensor networks to outline design considerations of protocols for mobile environments. The selected protocols are compared on the basis of multiple parameters, which include packet delivery ratio, packet loss, network lifetime, and control overhead using variable number of nodes and speeds. The extensive simulation and analysis of results show that position-based routing protocols incur less packet loss as compared to the non position based protocols. However, position-based protocols require localization mechanism or a GPS for the location information, which consumes energy and affects the network lifetime. Alternatively, non position-based protocols are more energy efficient and provide extended network lifetime.

Pakistan Veterinary Journal , 2012,
Abstract: The aim of this study was to develop a procedure to adjust lactations of longer duration to a standard such as 305-days when standard lactation milk yield for such lactations could not be recorded. For Sahiwal cattle and Nili-Ravi buffaloes, information on completed lactations for duration of more than 305-days was used for 3054 and 3927 lactations, respectively. Final regression equations to predict standard lactation milk yield (305-day milk yield) (SLMY) from completed lactation milk yield (CLMY) and lactation length (LL) were obtained using multiple regression analysis.SpeciesRegression equationsR2 (%) VIFSahiwal CattlePredicted SLMY = 1239 + 0.967 (CLMY) - 3.80(LL)96.5 0.035Nili-Ravi BuffaloesPredicted SLMY = 1604 + 0.925 (CLMY) - 4.75 (LL)96.1 0.039Thus, standard lactation milk yield can be fairly adequately predicted from total milk yield of longer lactations and lactation length using linear regression technique both in Sahiwal cattle and Nili-Ravi buffaloes with reasonable accuracy.
Jovian Problem: Performance of Some High-Order Numerical Integrators  [PDF]
Shafiq Ur Rehman
American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.33028

N-body simulations of the Sun, the planets, and small celestial bodies are frequently used to model the evolution of the Solar System. Large numbers of numerical integrators for performing such simulations have been developed and used; see, for example, [1,2]. The primary objective of this paper is to analyse and compare the efficiency and the error growth for different numerical integrators. Throughout the paper, the error growth is examined in terms of the global errors in the positions and velocities, and the relative errors in the energy and angular momentum of the system. We performed numerical experiments for the different integrators applied to the Jovian problem over a long interval of duration, as long as one million years, with the local error tolerance ranging from 10-16 to 10-18.
