F. Zafar,R. Saifullah Hassan,Z. Mahmood
Journal of Economics, Business and Management , 2014, DOI: 10.7763/joebm.2014.v2.131
Abstract: This paper highlights best practices of technological influenced e-government using ICT, emerging mobile and web 2-0 technology for the effective health Care & disease management system. Modern technology has given a whole new dimension to the concept of good governance, thus embarking a strong and effective influence on citizens and cultural trends. Authors have investigated successful case studies, which are taken from existing practice of egovernment health care projects within Pakistan. Pakistan was hit by the epidemic of dengue, affecting over 350,000 people in 2010. Due to the unprecedented scale of epidemic, the basic health infrastructure was not ready to address the issue. However by 2012 a monitoring mechanism was devised as an e-Govt health care activity, to log all field activities related to prevention/eradication of the disease. The project focused mobile reporting using android phones, EDGE services, and Google maps. 650 smart phones users reported 43,000 activities. The information received was extrapolated to bring all stakeholders of anti-dengue campaign on a single platform and DIMS (Dengue Information Management System) was conceived. Features of DIMS include: A central dashboard to view and dispose of complaints on real-time coming in from the Helpline and Hospitals e-CRS (Electronic Complaint Routing System). 2 Vector Surveillance System for tracking and reporting all indoor / outdoor larvaciding activities. 3 A Disease Reporting System to manage the clinical and lab diagnosis records of dengue affected patients. Utilization of this system has resulted in 0 % deaths reported due to dengue in the past 1.5 years. Careful investigation of step by step usage, reporting to DMIS with Android phone and working behavior of ICT infrastructure are elaborated in this research.

H. Kh. Ismail,M. Z. Mahmood
Iraqi Journal of Veterinary Sciences , 2011,
Abstract: Seventy kidney samples of broiler chickens 3-6 weeks old were collected from private chicken farms in Mosul province, used to study gross and histopathological changes in the kidneys. The most prominent gross pathological changes were variable ranging from swelling and congestion of kidney with petechial hemorrhage on the cortex to swelling and congestion w while other cases of kidney appears pale and small in size. Histopathological changes of the kidneys were characterized by acute tubular nephrosis leading to necrosis and desquamation of epithelial lining the renal tubules degeneration of the epithelial cell of renal tubules to diffuse degeneration of the epithelial cells of renal tubules leading to necrosis and desquamation of epithelial cells. Additionally there is infiltration of inflammatory cells (Lymphocytes) in the interstitial tissue of the kidney. In other samples the histological changes appears as proliferation in the mesengial cell of glomeruli with sever hemorrhage in the interstitial tissue. Also there is hyaline degeneration in the renal glomeruli. Moreover visceral gout was seen in some samples of kidney characterized by deposition of urates as clefts in the lumen of renal tubules with infiltration of inflammatory cells especially foreign body giant cell and macrophages in addition to congestion of blood vessels and hemorrhage in the interstitial tissue. From the result of the present study it was concluded that renal pathological changes occurred in broiler chicken associated with many diseases.

Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.517177
Abstract: The present article examines the contribution of building a portfolio to the professional development of teacher educators, and the effectiveness of their progress within the organized framework. The results of long-time research that was carried out in a college for teachers’ education show the contribution of the derivative works that contain reflection and accompanies reflective thinking meetings for professional progress of teacher educators; for strengthening their motivation; for improving their level of education and ensuring its quality; to develop their involvement in the duty they are fulfilling and for a annual and future planning cultivation. Moral education, values and attitudes via acquiring knowledge in science content knowledge as Dreyfus (1995) emphasized that “biological knowledge is a prerequisite for the development of students’ values and attitudes”. Science knowledge role is not only for academic achievement and mastery of cognitive and metacognitive skills, but to educate students on the affective domain being active in the community life based on moral and ethical values, and positive attitudes toward societal issues, like social justice, preservation of the environment and peace, the last two being addressed due to the fact of having a mutual impact connection in one of the STS learning units presented.

M Naeem, A Mahmood, S Khan, Z Shahiq
Tropical Journal of Pharmaceutical Research , 2010,
Abstract: Purpose: To develop and characterize bilayer tablet formulations of tramadol HCl (TmH) and acetaminophen (AAP) microparticles. Methods: Coacervation via temperature change was the encapsulated method used for the preparation of the microparticles, with ethyl cellulose (EC) of medium viscosity as the polymer for extending drug release. The microparticles of the two drugs were prepared separately and then compressed into bilayer tablets. The physicochemical compatibility and stability of the tablets were determined by Fourier transform infrared spectroscopy (FTIR), x-ray diffractometry (XRD), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) while their mechanism and pattern of drug release were assessed by applying Higuchi, Zero order, First order and Korsmeyer-Peppas kinetic models. Bilayer tablets were subjected to accelerated stability studies for three months. Results: FTIR, XRD, DSC and TGA data for the formulations indicate good compatibility and stability. Furthermore, accelerated stability studies confirmed the stability of the formulations. Controlled drug release from the microparticles and bilayer tablets was observed for 8 h and 12 h, respectively. The Higuchi model produced the best fit, with regard to release profile, for both drugs, with correlation coefficient (R2) of 0.966 and 0.960 for AAP and TmH, respectively. Conclusion: Microencapsulated TmH and AAP can be developed into suitable bilayer tablets that are stable and capable of releasing the drugs over 12 h.

Abstract: This paper reports the physicochemical characteristics of the seed oils from different varieties of watermelon (Citrullus lanatus) cultivated in Pakistan, namely Sugar Baby, Q-F-12, D-W-H-21 and Red Circle-1885. The oil and crude protein contents from watermelon seeds, within the range of 28.25 to 35.65% and 20.50 to 35.00%, respectively, varied significantly (p < 0.05) among the varieties tested. The levels of moisture, ash, and crude fiber in the seeds tested were found to be 2.16-3.24%, 1.95-3.42% and 4.29-6.60%, respectively. The physicohemical characteristics of the extracted oils were: free fatty acid contents (1.17-2.10% as oleic acid), iodine value (97.10-116.32 g of I2 100g-1 of oil), saponification index (190.20-205.57 mg KOH g-1 of oil), unsaponifiable matter (0.54-0.82%) and color (1.12-4.30 R + 12.20-33.40 Y). The oils revealed a reasonable oxidative parameter range as depicted by the determinations of specific extinction at 232 and 270 nm (2.90-4.40 and 2.05- 3.09, respectively), p-anisidine value (5.60-7.70) and peroxide value (2.90-5.06 meqO2 kg-1 of oil). Linoleic acid was the major fatty acid found in all the seed oils with contributions of 45.30-51.80% of the total fatty acids (FA). Other fatty acids detected were known to be oleic acid (20.2- 23.5%), palmitic acid (15.1-16.9%) and stearic acid (11.5- 14.4%). The contents of α- and δ-tocopherol in the oils accounted for 120.6-195.6 and 9.1-58.3 mg kg-1, respectively. The physicochemical attributes of the watermelon seed oils showed a wider variation among the varieties tested. The results of the present study indicate that the seeds of the tested watermelon varieties from Pakistan are a potential source of high-linoleic oil and thus can be explored for commercial use and value addition.

M. Q. L. Bhatti,Z. A. Cheema,T. Mahmood
Pakistan Journal of Biological Sciences , 2000,
Abstract: Sorgaab (water extract of mature Sorghum bicolor plants) was evaluated for its effect on weeds in Raya crop and it was compared with commonly employed weed control practices i.e hand weeding and a herbicide-pendimethalin in a field trial during 1998. Results revealed that Spraying of sorgaab at 15,30 and 45 Days After Sowing (DAS) reduced dry weight of all weeds by 45-85 % while herbicidal treatment reduced dry weight by 45 % . The yield of Raya crop was significantly enhanced (33-58 %) with sorgaab over control. Hand weedings (one and two) at 15+30 DAS increased Raya seed yield by 40-72 % while herbicidal treatment improved the seed yield by 26 % and was uneconomical due to higher cost as compared with one, two and three sprays of sorgaab.
Pakistan Veterinary Journal , 2007,
Abstract: A total of 84 male Japanese quails (Coturnix japonica) of 40 days of age were randomly divided into seven groups (A to G) with 12 birds in each group. A corn and soybean meal based feed having 25% proteins was offered to group A (control) as a basal feed. Three isonitric and isocaloric experimental feeds prepared by replacing soybean meal with varying proportions of cottonseed meal (CSM) were offered to groups B and C (13% CSM), D and E (27% CSM) and F and G (41% CSM). Feeds of groups C, E and G were also supplemented with 2% lysine. Duration of experiment was 42 days. Frequency of mounting, crowing and presence of foamy droppings were lower in groups having high percentage of CSM. Body weights of CSM fed groups were significantly lower from that of control group till week 5 and dietary supplementation of lysine rendered this difference non significant. Differences in body weights at week 6, however, were non significant between control and treated groups. At week 3, testicular weight of birds in groups B and F were significantly lower than that of control, while lysine supplementation rendered this difference non significant. Seminiferous tubules of all CSM fed groups had necrotic cells characterized by dark and small pyknotic nuclei of round spermatids in some tubules. Liver of groups D, E, F and G had cytoplasmic vacoulation of hepatocytes and newly formed bile ducts. Supplementation of lysine in experimental CSM feeds partially ameliorated the effects of CSM on body weight, testes weight and clinical signs.

Journal of Agronomy , 2004,
Abstract: A pot experiment was conducted in the greenhouse to evaluate the effect of calcium carbide (as a source of ethylene) on some agronomic parameters of wheat (Triticum aestivum L., var. Inqalab-91) that was grown without or with two levels of N, P and K fertilizers (120-90-60 kg ha-1 and 60-45-30 kg ha-1). Half dose of N and full dose of P and K was applied at sowing while remaining half after one week of germination. Calcium carbide as a source of ethylene was applied at 60 kg ha-1 after 2 and 8 weeks of germination. A factorial completely randomized design was followed with nine treatments each with three replicates. Data regarding plant height, number of tillers, length of spike, number of spikelets spike-1 and grain yield was recorded. Plant height, number of tillers and spike length were significantly affected when CaC2 was applied after one week of germination while number of spikelets and grain yield was maximum when CaC2 was applied after 8 weeks of germination
