T. Ahmad,I. Ahmad,M. Qasim
Journal of Tekirdag Agricultural Faculty , 2008,
Abstract: Present status and future prospects of gladiolus cultivation in Punjab, Pakistan were investigated so as to explore the potential areas for gladiolus cultivation, analyze the trends prevailing in the area, study the infrastructural facilities available for gladiolus cultivation and study the socio-economic conditions of growers. It was concluded that gladiolus is a potential crop but the practices being performed by the farmers at present time are not according to the international standards and government and private agencies should help the growers for the uplift of the gladiolus industry.

M. Ahmad, N. Ahmad, I. Ahmad, N. Akhtar and S. Ali
Pakistan Veterinary Journal , 2004,
Abstract: In this study 215 buffaloes and 180 cows with the history of repeat breeding and prolonged oestrus period (>24 hours) were used. All of the animals had repeated at least twice. A total of 95 animals (50 buffaloes and 45 cows) were inseminated once, 12-18 hours after the start of oestrus and were kept as control, while 165 buffaloes and 135 cows were divided into two treatment groups. In group I, 70 buffaloes and 55 cows were inseminated twice, first at 12-18 hours after the start of oestrus and then 12-24 hours later. In group II, 95 buffaloes and 80 cows were inseminated once at 12-18 hours after the start of oestrus. These animals were then subjected to forced racing for at least 30 minutes. In control group, 18 buffaloes (36%) and 15 cows (33.33%) were found to be pregnant 60 days after insemination. In treatment group I, 36 buffaloes (51.43%) and 30 cows (54.55%), whereas in group II, 70 buffaloes (73.68%) and 58 cows (72.50%), were observed to be pregnant. These results indicate that forced racing may be a good practical and economical tool to improve conception rate in repeat breeder animals where the problem is due to delayed ovulation.
Pellet Embolization after Subclavian Artery Injury: A Case Report  [PDF]
Raminta ?ernevi?iūt?, Shaheel M. Sahebally, Ahmad Mourad, Donatas In?iūra, Aleksandras Antu?evas
Surgical Science (SS) , 2017, DOI: 10.4236/ss.2017.810049
Abstract: Acute upper limb ischemia caused by a gunshot penetrating vascular injury and subsequent arterial embolization by foreign body is uncommon in everyday practice and is associated with high morbidity/mortality rates, especially with emergency surgery. We present the case of a 72-year old male who attempted suicide using a gun. A gunshot entry wound was evident in the right upper chest region with no pellet exit wound. Radial pulses were palpable bilaterally. Angiography revealed right subclavian artery direct injury and pellet embolization to the brachial artery. The patient underwent open surgery, with reversed saphenous vein interposition graft to replace subclavian artery defect. A pellet was removed by a separate arteriotomy in the brachial artery. Associated injuries were clavicle-comminuted fracture and subclavian vein injury. The patient remained well 5 months later with no reported complications. In conclusions, the presence of radial pulses alone on clinical exam cannot rule out the presence of a significant vascular injury.
DESULPHURIZATION OF LIQUID FUELS BY SELECTIVE ADSORPTION THROUGH MINERAL CLAYS AS ADSORBENTS
M SHAKIRULLAH,W AHMAD,I AHMAD,M ISHAQ
Journal of the Chilean Chemical Society , 2012,
Abstract: Different clays collected from local sources, including Kaolinite, Montmorollinte, Palygorskite and Vermiculite have been utilized for the selective adsorption of sulphur compounds prevailing in petroleum products i.e. crude oil, kerosene and diesel oil. The desulphurization activity of the clay was compared with the charcoal, ion exchange resins and with each other. Desulphurization was performed in batch operation at different time intervals i.e 1, 3 and 6 hrs at 40 oC temperature. Out of different adsorbents used, Kaoilinte exhibited the maximum desulphurization yield of 60 %, 76 % and 64 % at 6 hrs adsorption incase of crude oil, kerosene and diesel oil respectively. All the mineral clays adsorbents were characterized by surface area, SEM and EDX analysis. The FT-IR study of the desulphurized fractions revealed that mostly high molecular weight thioles and thiophenic compounds were depleted during adsorption process.

International Mathematical Forum , 2013,
Abstract: We find some interesting relations between right alternative andleft nuclear square AG-groupoids such as (1) A right alternative AG-groupoidS is left nuclear square, (2) For a right alternative AG-groupoidS the conditions (i) S is right nuclear square, (ii) S is middle nuclearsquare, (iii) S is nuclear square, are equivalent, (3) a right alternativeAG -groupoid S is nuclear square, and (4) a cancellative left nuclearsquare AG-groupoid S is T1-AG-groupoid.
Fodder Yield and Quality of Four Cultivars of Maize (Zea mays L.) Under Different Methods of Sowing
M. Ayub,R. Ahmad,A. Tanveer,I. Ahmad
Pakistan Journal of Biological Sciences , 1998,
Abstract: Response of maize (Zea mays L.) cultivars viz., Sadaf, Sultan, Sarhad White and Golden to two sowing methods, i.e., broadcast and line sowing was studied under field conditions. Significant differences were observed amongst the cultivars for plant height, leaf area per plant, stem diameter, fresh fodder yield and ether extractable fat percentage. Cultivar Sultan proved superior to all other cultivars with respect to higher fodder yield of better quality. Plant population was significantly higher under line sowing where as fodder yield and all other yield parameters studied were not significantly affected by sowing methods.
EFFECTS OF AGE AND SEASON ON THE BODY WEIGHT, SCROTAL CIRCUMFERENCE AND LIBIDO IN NILI-RAVI BUFFALO BULLS MAINTAINED AT THE SEMEN PRODUCTION UNIT, QADIRARAD

Pakistan Veterinary Journal , 2003,
Abstract: This study was carried out to investigate effects of age and season on body weight, scrotal circumference and libido in 18 Nili-Ravi buffalo bulls kept at the Semen Production Unit, Qadirabad. Depending on age, these bulls were divided into three equal groups viz. young (3-4 years of age), adult (5-8 years of age) and old (12-15 years of age). Body weight and scrotal measurements were made at monthly intervals while libido of each bull was assessed weekly during the low (May to July) and the peak (September to November) breeding seasons. The results indicated that the body weight of adult and old bulls was higher (P<0.05) than young bulls. Similarly. The body weight was higher during peak than low breeding season. Scrotal circumference was higher in adult and old bulls than young bulls and during peak than low breeding season (P<0.05). The libido of the adult bulls was higher than young or old bulls, and during the peak than the low breeding season. It was concluded that body weight, scrotal circumference and libido of Nili-Ravi buffalo bulls were significantly affected by age of the bull and season of the year.

M. S. ULLAH, M. AHMAD, N. AHMAD, M. Z. KHAN1 AND I. AHMAD
Pakistan Veterinary Journal , 2006,
Abstract: The aim of the present study was to explore the fetotoxic effects of cypermethrin (CY) in female rabbits with low and high doses. For this purpose, 32 adult female rabbits were divided in to four equal groups A, B, C and D. Rabbits of groups A, B and C were treated with different levels of CY at the dose rate of 25, 50 and 75 mg/kg body weight intraperitoneally, while the group D served as a control and was given equal volume of normal saline intraperitoneally. The clinical signs exhibited by the rabbits treated with CY included salivation, licking of different body parts, muscular tremors, ataxia and convulsions. There was a significant difference in the numbers of CL and number of fetuses which mean the early embryonic death and post implantation loses at the high dose. There were microscopic changes in the ovaries and uteri of animals treated with CY.
Numerical prediction of wind loads on low buildings
S Ahmad, M Muzzammil, I Zaheer
International Journal of Engineering, Science and Technology , 2011,
Abstract: In the present study, 2-D numerical simulation of wind loads on low-rise buildings has been carried out. The simulation was carried out under FLUENT package environment in which full-scale Reynolds number, boundary layer and turbulence properties have been simulated. Wind loading effect numerically obtained on flat roof (TTU building) and pitched roof is compared with wind tunnel data. It was found that there is fair agreement between the numerical predictions and measurements for time-averaged wind loads on buildings. The computed pressure coefficients have been validated with wind tunnel TTU building model results on 1:100 scale within an average error of 20%. The effect of roof pitch for 10°, 20° & 30° on pressure coefficients for gable roof has also been investigated and the results were compared with the available wind tunnel results for 15°, 26° & 35° roof pitch. The present study shows that the numerical simulation of wind loads hold a great potential for extending codes of practice for wind loads.
