Purification and Characterization of Serine Protease from Seeds of Holarrhena antidysenterica
Hidayatullah Khan,M. Subhan,Sultan Mehmood,M. Faran Durrani
Biotechnology , 2008,
Abstract: Low molecular weight serine protease has been purified from the seeds of Holarrhena antidysenterica to electrophoresis homogeneity by the combination of size exclusion and ion exchange chromatography. The molecular mass was estimated by SDS-PAGE to be about 25 kDa. The enzyme showed optimum activity at pH 7.5 and exhibited its highest activity at 35°C using 1% casein as a substrate. The enzyme was strongly inhibited by 2 mM PMSF but not by EDTA and cysteine protease inhibitors, suggesting the presence of serine residues at the active site. The enzyme had a Km of 1.1 mg mL-1 and Vmax of 389.71 units min-1 mg-1 of protein.

Sensors , 2006, DOI: 10.3390/s6091153
Abstract: Thin films of tin oxide were deposited by electron beam evaporation. The effectsof the sensor biasing voltage and film thickness on the CO-sensing of tin oxide thin filmswere investigated. The films were characterized using X-ray diffraction and X-rayphotoelectron spectroscopy All the films were found to be amorphous. The current-voltagecharacteristic of the sensor in air has shown that semiconductor-metal interface formsSchottky barrier. It was found that the CO-sensing properties depend on the sensor biasingvoltage and film thickness. For lower biasing voltages the sensitivity was much higher thanfor the higher voltages. It was found that the sensitivity of the films to CO increased withthe film thickness.

International Journal of Poultry Science , 2003,
Abstract: A systematic investigation was performed on the outbreaks of Infectious Bursal Disease (IBD) using data compiled during the years 1997 and 1998 from 50 broiler farms in Mirpur and Kotli districts. Average mortality due to IBD was 15.31±1.04% with a coefficient of variation of 48.04%. Farms located at various places and vitamin supplementation had no effect on mortality caused by IBD. Season, floor space/broiler, age of the bird, immunization schedule, interval between two batches, presence of coccidiosis in a flock and hygienic status of the farm had a significant effect (p<0.01) on prevalence of IBD. Higher losses (p<0.05) were found due to IBD in winter (19.84±2.10%) than those tabulated in spring season (9.00±2.74%). Losses were found to be higher (p<0.05) in over crowded houses (20.34±3.93%; <0.09m2/broiler) than in under (12.56±2.53%; >0.09m2/broiler) or optimally utilized housing (13.04±1.06%; 0.09m2/broiler). Significantly higher (p<0.05) losses were found in broilers at the age above 32 days (17.66±1.51%) than in broilers at 19-23 days of age (12.42±1.97%). Prevalence of IBD was higher (p<0.05) in those flocks immunized only once in their production life (23.03±1.27%) than in those produced under a standard immunization schedule (7.61±4.89%). Losses due to IBD were also higher when the duration between two batches was one week (22.28±10.28%) than at four week duration between two batches (12.80±2.78%). Insignificant differences were assessed in losses due to IBD when inter flock interval was either 2 or 3 week periods. Significantly higher (p<0.05) losses were found due to IBD in flocks experiencing coccidiosis problem (17.90±1.20%) than those having no coccidiosis problem before the onset of IBD (12.73±1.85%). Losses were less in flocks maintained under good hygienic conditions (6.03±1.33%) than those under poor hygienic conditions (21.63±2.19%). Mean economic losses due to IBD per broiler flock of 1734.50±119.91 and a flock of 1000 birds were Rs. 7846.87±1169.81/ and Rs. 4523.99±447.56/, respectively. Economic losses/year for the aforementioned flocks was Rs. 31701.38±2345.36/- and Rs. 18276.96±2388.91/-, respectively. Optimal utilization of floor space/broiler, protection of birds from extreme climatic conditions, following recommended immunization schedule, maintenance of good hygienic conditions at the farm and a flock interval of at least more than one week are suggested as important factors for reducing losses due to IBD in broilers in Mirpur and Kotli districts of Kashmir.

MIMO Identical Eigenmode Transmission System (IETS) - A Channel Decomposition Perspective
M. Zeeshan Shakir,Tariq S. Durrani
Mathematics , 2010,
Abstract: In the past few years considerable attention has been given to the design of Multiple-Input Multiple-Output (MIMO) Eigenmode Transmission Systems (EMTS). This paper presents an in-depth analysis of a new MIMO eigenmode transmission strategy. The non-linear decomposition technique called Geometric Mean Decomposition (GMD) is employed for the formation of eigenmodes over MIMO flatfading channel. Exploiting GMD technique, identical, parallel and independent transmission pipes are created for data transmission at higher rate. The system based on such decomposition technique is referred to as MIMO Identical Eigenmode Transmission System (IETS). The comparative analysis of the MIMO transceiver design exploiting nonlinear and linear decomposition techniques for variable constellation is presented in this paper. The new transmission strategy is tested in combination with the Vertical Bell Labs Layered Space Time (V-BLAST) decoding scheme using different number of antennas on both sides of the communication link. The analysis is supported by various simulation results.

Pakistan Journal of Biological Sciences , 2001,
Abstract: Egg and shell weight, egg length and width, % hatchability, fertility, loss in egg contents during incubation and weight of newly hatched chicks were studied in 120 eggs (40 eggs each of Fayumi, Rhode Island Red (RIR) and Desi chicken). %hatchability on the basis of total eggs set and on the basis of fertility was higher in Fayumi (65.96±0.07 vs. 88.57±0.08%) than in Desi (60.00±0.18 vs. 61.76±0.08%) and RIR chicken (42.86±0.07% vs. 80.77±0.10%). Higher fertility was found in Desi (74.47±0.08%) than in Fayumi (64.71±0.23%) and RIR chicken (53.06±0.45%). Larger egg weight and chicken weight was found for RIR (53.94±0.69 vs. 35.32±0.86 g) than for Desi (45.88±0.67 vs. 33.84±0.83 g) and Fayumi chicken (44.84±0.54 vs. 30.74±0.72 g). Egg weight was found significantly and positively correlated (r=0.4962) with hatching chick weight. Percent loss in egg contents was higher in RIR (24.41±0.42%) than in eggs of Fayumi (22.11±0.36%) and Desi chicken (19.18±0.38%). Egg shell weight was larger in RIR (4.77±0.09 g) than in Fayumi (4.54±0.09 g) and Desi chicken (4.46±0.06 g). Shell was thicker in RIR (0.39±0.01 mm) and Fayumi (0.38±0.01 mm) than in Desi chicken (0.34±0.02 mm). Egg length (5.57±0.03 cm) and width (4.19±0.02 cm) were higher in RIR chicken than in Desi (5.26±0.03 vs. 3.96±0.02 cm) and Fayumi eggs (5.17±0.03 vs. 3.93±0.02 cm). Egg length to width ratio was around 1.33 and non-significant differences were found in all types of chicken. Egg length (r=0.446) and width (r=0.426) was found significantly correlated with hatching chick weight. Egg weight (r=0.184), shell weight (r=- 0.504), egg length (r=0.581) and width (r=0.78) were also found significantly correlated with hatching chick weight. On the other hand egg length (r=-0.187) and width (r=-0.181) were found negatively and significantly correlated with % hatchability. On overall basis Fayumi chicken performed better than RIR and Desi chicken.
Solition behaviour in models of baroclinic instability

Iranian Journal of Physics Research , 2000,
Abstract: Here we concern ouraelves with the derivation of a system of evolution equations for slowly varying amplitude of a baroclinic wave packet. The self-induced transparency, Sine-Gordon, and nonlinear Schrodinger equations, all of which possess soliton solutions, each arise for different inviscid limits. The presence of viscosity, however, alters the form of the evolution equations and changes the character of the solutions from highly predictable soliton solutions to unpredictable chaotic solutions. When viscosity is weak, equations related to the Lorenz attractor equations obtain, while for strong viscosity the Ginzburg-Landau equation obtain.

Abstract: Twenty adult healthy quails (Coturnix coturnix) were divided into two equal groups. One group was administered detomidine (2.4 mg/kg, I/M) and other group was administered detomidine-ketamine cocktail (1.2 mg/kg + 30 mg/kg, I/M). Detomidine slowly and smoothly induced a light sedation accompanied by superficial analgesia, hypoventilation, hypothermia and bradycardia in all birds. Detomidine-ketamine cocktail rapidly and smoothly induced a deep anaesthesia accompanied by deep analgesia, hypoventilation, hypothermia and bradycardia and complete loss of all reflexes in all birds. In both groups, recovery from sedation and anaesthesia was smooth and of short duration. From this study it was concluded that for minor and least painful procedures in quails detomidine can be used alone, while for major and painful surgical procedures detomidine-ketamine combination should be preferred.

Where; ` `was predicted egg weight, X1 and X3 the egg length and X2 and X4 the egg width for every equation separately. Following equations were developed for predicting eggshell weight from egg weight, length and width; (Equation 4) =- 0.521102+0.310761(X5) +0.4074 (X6), (Equation 5) =0.138189+0.062933(X7) +0.233078(X8) and (Equation 6) =- 0.001150+0.071568(X9) +0.311496(X10). Where was predicted eggshell weight, X5 and X8 were egg length, X6 and X10 are egg width and X7 and X9 were egg weight (g), respectively. Shell thickness was predictable with sufficient accuracy from egg weight, width and length and following equations were developed to predict it; (Equation 7) = 0.154646 + 0.076448(X11) and (Equation 8) = 0.154721 + 0.000694(X12) + 0.073939(X13). Where ` ` was predicted eggshell thickness, X11 and X13 the egg width and X12 the egg weight for each equation separately. Weight of egg albumin was predictable from the following equations; (Equation 9) = - 0.685557 + 0.460613(X14) + 0.079842(X15) + 0.412241(X16), (Equation 10) = - 0.553150 + 0.468198(X17) + 0.426649(X18), (Equation 11) = 0.279557 + 0.468198(X19) and (Equation 12) = - 2.128934 + 0.925133(X20) + 1.63522(X21). Where ` ` was the predicted weight of egg albumin, X14, X17 and X19 the egg weight, X15 and X20 the egg length in cm and X16, X18 and X21 the egg width in cm for each equation separately.

Abstract: Twenty female farmers in each of 20 different villages of district charsadda, NWFP were selected at random to investigate prevalence and economic ramification of Newcastle disease in Backyard chicken. Overall Morbidity and mortality was 31.0 1.84 and 26.98 1.14%, respectively causing 86.95 0.79% mortality among the sick birds. Morbidity (56.93 7.61) and mortality (98.66 7.03%) among the sick birds was higher (p<0.05) in White Leghorn (WLH) than in Fayumi (17.94 2.22 and 74.28 1.91), Rhode Island Red (RIR; 27.79 3.73 and 90.67 3.71) and Local chicken (20.82 1.34 and 84.24 0.89%, respectively). Overall mortality was also higher in WLH (49.23 6.92%) than in Fayumi (14.36 1.89%), RIR (24.10 3.36%) and Local (20.18 1.18%) morbidity (49.19 1.56%), mortality among the sick birds (99.89 0.93%) and overall mortality (44.88 1.45%) was higher (p<0.05) in those flock which were not vaccinated flocks than in flocks regularly vaccinated (12.84 1.01, 65.96 2.02% and 8.92 0.84%, respectively). Morbidity (46.82 2.35%) and mortality among the sick birds (98.58 0.27%) was higher (p<0.05) in chicks than in adult birds (17.63 1.23 and 76.06 1.80%) and pullets (28.92 2.49 and 85.79 0.87%, respectively). Overall mortality was also higher in chicks (40.71 1.52) than in adult birds (15.76 0.91%) and Pullets (24.39 1.07%). Higher morbidity and mortality (among the sick birds) was observed in winter season (72.08 0.84 and 98.82 0.82) than in Summer (29.45 0.78 and 90.93 0.89), Fall (14.63 0.68 and 82.78 1.03) and Spring season (8.28 0.72% and 74.08 1.2%, respectively). Overall mortality was also high in winter (68.7 0.79%) than in Summer (22.34 0.7%), Fall (11.26 0.8%) and Spring (5.65 0.93%). Although, not significant, morbidity and mortality (among the sick birds) was numerically high (32.16 2.01 and 96.43 2.68%) in chicken having no shelter facility than in those which had a night shelter facilities (30.03 1.95 and 77.51 1.79%, respectively). Per cent morbidity had a non-significant association (b=-0.6341 0.085) with per cent reduction in egg production. Per cent morbidity was found significantly (p<0.05) and negatively associated with per cent reduction in eggs of RIR (b=-0.2254 0.572) and local chicken (b=-0.14862 0.047). Per household annual reduction in eggs and economic ramification due to reduced egg production, and mortality were 401.06 1.14 eggs and Rs. 902.45 0.56, and Rs. 1343.84 2.8, respectively. Total per household per year economic ramification due to reduction in eggs and mortality resulting from Newcastle disease was Rs. 2246.29 1.19. Per household per cent redu
