On quasi -pure submodules of QTAG-modules
Mohd. Z. Khan,A. Zubair
International Journal of Mathematics and Mathematical Sciences , 2000, DOI: 10.1155/s016117120000288x
Abstract: Different concepts and decomposition theorems have been done for QTAG-modules by number of authors. We introduce quasi h-pure submodules for QTAG-modules and we obtain several characterizations for quasi h-pure submodules and as a consequence we deduce a result done by Fuchs 1973.

Hemato-biochemical and clinico-epidemiological aspects of parturient hemoglobinuria in Nili-Ravi buffaloes
A. Khan,M. Z. Akhtar
Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2007.s2.953
Abstract: For this study, 60 buffaloes suffering from parturient hemoglobinuria (PHU) were randomly selected from field cases occurring in three districts of Punjab, Pakistan and simultaneously, 60 clinically healthy buffaloes of similar description from the same localities were included for case control study. Clinico-epidemiological data were collected. Blood/serum samples from all buffaloes were collected and analyzed. The most prominent clinical sign was passing of red to coffee colored urine. Milk production was reduced and respiration and pulse rates were significantly accelerated. Ruminal motility was significantly weak and reduced along with characteristic straining while defecating. The case fatality was 15%. A significantly high occurrence of PHU was observed in the winter season (41.8%). Maximum number of affected buffaloes (25.0%) was in 4th lactation. Twenty-seven (45.0%) buffaloes developed hemoglobinuria in the post calving period and majority (59.3%) of these were within 1-23 days of calving. Of the 33 (55.0%) PHU affected pregnant buffaloes, 18 (54.6%) were in their third trimester. The highest cases of PHU were observed in buffaloes producing 10 or more liters of milk/day (42.5%). Recurrence of PHU was observed in 18.3% buffaloes. Mean values of total erythrocyte counts, hemoglobin concentration and packed cell volume were lower (P<0.001), while erythrocyte sediment rate was higher (P<0.001) in PHU affected buffaloes as compared to the values in healthy buffaloes. Neutrophils were significantly higher, while lymphocytes and erythrocytic glucose-6-phosphate dehydrogenase (G6PD) were lower, in PHU affected buffaloes than in healthy buffaloes. Serum phosphorus, copper and selenium were significantly (P<0.001) lower, whereas potassium, iron and molybdenum (P<0.001) were higher in buffaloes suffering from PHU than healthy buffaloes.
TSEP: Threshold-sensitive Stable Election Protocol for WSNs
A. Kashaf,N. Javaid,Z. A. Khan,I. A. Khan
Computer Science , 2012,
Abstract: Wireless Sensor Networks (WSNs) are expected to find wide applicability and increasing deployment in near future. In this paper, we propose a new protocol, Threshold Sensitive Stable Election Protocol (TSEP), which is reactive protocol using three levels of heterogeneity. Reactive networks, as opposed to proactive networks, respond immediately to changes in relevant parameters of interest. We evaluate performance of our protocol for a simple temperature sensing application and compare results of protocol with some other protocols LEACH, DEEC, SEP, ESEP and TEEN. And from simulation results it is observed that protocol outperforms concerning life time of sensing nodes used.
SOME OF THE RISK FACTORS OF NILI-RAVI BUFFALO (BUBALUS BUBALIS) NEONATAL CALF MORTALITY IN PAKISTAN
T. ZAMAN, A. KHAN AND M. Z. AKHTAR
Pakistan Veterinary Journal , 2006,
Abstract: This study was carried out to investigate neonatal calf mortality (NCM) in 864 Nili-Ravi buffalo calves born during 1993-2000 at the Livestock Production Research Institute (LPRI), Bahadurnagar, Okara, Pakistan. The overall mortality in buffalo neonates was 9.4%. The NCM in relation to birth weight, sex and age of neonatal calf showed non-significant difference. The highest mortality was recorded during 2nd week of age (35.0 and 39.0%) and summer season (11.5 and 12.3%) in male and female buffalo neonatal calves, respectively. Mortality was also high in calves born to first parity dams (11.3%). Morbidity and mortality due to various disease conditions showed highly significant (P = 0.0001) difference. Neonatal calf diarrhoea (NCD) rendered the highest morbidity (16.6%) and mortality (5.2%), followed by pneumonia and pneumono-enteritis. Mange (3.4%), navel-ill (3.1%) and umbilical hernia (1.6%) lead morbidity only. Relative risk of morbidity (two and seven times) and mortality (three and eight times) was more in calves with intermediate and low immunoglobulins (Igs) concentration, respectively as compared to calves having high Igs concentration (P = 0.000).
QUARTER-WISE COMPARATIVE PREVALENCE OF MASTITIS IN BUFFALOES AND CROSSBRED COWS
A. Z. Khan and G. Muhammad1
Pakistan Veterinary Journal , 2005,
Abstract: The present study was designed to determine the quarter-wise comparative prevalence of mastitis in buffaloes and crossbred cows. Milk samples collected from 50 dairy buffaloes and 50 crossbred cows were tested for subclinical mastitis by Surf Field Mastitis Test. In addition, all milk samples were processed for isolation and identification of pathogens. In buffaloes, overall prevalence of subclinical mastitis was 27%, clinical mastitis 4% and blind quarters 10%. In crossbred cows, subclinical mastitis was observed in 36%, clinical mastitis in 5.5% and blind quarters in 8% quarters. Prevalence was higher (32%) in hindquarters of crossbred cows than those of buffaloes (29%). Among the isolates, Staphylococcus aureus showed the highest (45%) frequency, followed by Streptococcus agalactiae (23%), E. coli (18%) and Bacillus spp. (14%) in buffaloes. In case of crossbred cows, Staphylococcus aureus , Streptococcus agalactiae , E. coli and Bacillus spp. were isolated from 48, 30, 13 and 8% milk samples respectively.
Measles Antibody Titres In 0-5 Years Children At Aligarh
Kandpal S D,Malik A,Khan Z
Indian Journal of Community Medicine , 1999,
Abstract: Research Question: What is the level of measles antibodies in 0-5 year children? Objectives: 1.To assess the pattern of decline of maternal antibodies in 0-9 months infants. 2. To estimate the seropositivity for measles antibodies in vaccinated 9 months infants. Study design: Cross- sectional. Setting: Rural areas of District Aligarh, U.P. Participants: 456 children in the age group of 0-5 years. Statistical analysis: Percentages, correlation coefficient. Results: 1. In all the study subjects below 9 months of age, the transplacentally acquired maternal measles antibodies showed a linear decline with increase in age. Out of 202 study subjects who had been immunized against measles 195(96.50%) were seropositive and 7(3.5%) were seronegative for measles antibodies.
