Effects of dietary minerals on postmolt performance of laying hens
Sohail Hassan Khan,Abdul Rehman,Ansari Jehanzeb
Veterinary World , 2011,
Abstract: Four hundred and fifty Single Comb White Leghorn commercial layers (66-67 weeks-old) were housed 2 birds per cage for the molting procedure. The hens were divided into 5 treatment groups with 90 layers per treatment and 30 layers in each replicate per treatment group following completely randomized design. During molt period (2 Weeks), experimental birds were randomly assigned to five-treatment groups viz., A (15 ppm copper sulphate), B (20 ppm zinc oxide), C (20 ppm aluminium oxide), D (balanced layer diet without added minerals) and E (without induced molting as control). The birds in groups A, B, C and D were offered respective experimental diets at the rate of 30 g/bird except bird's in-group E (ad libitum) and lighting program was followed as 12L: 12D. During rest period (3 Weeks) the birds in groups A, B, C and D were given respective experimental diet at the rate of 50 g/bird for first 2 weeks of the rest period. During 3rd week of rest period the birds in groups A, B, C and D were given experimental diets at the rate of 60 g/bird and were placed on lighting program of 14L:10D. During production phase, the birds of all groups were fed a balanced layer diet (ad libitum) and birds were placed again on lighting program of 16L:8D. The results showed that the birds fed diets A, B and C showed greater (p<0.05) percentages of body mass loss than those fed the diet D. The birds fed diet E (Full feed-non molted group) exhibited the least amount of body mass loss when compared with all other treatments of molted hens. Un-supplemented mineral group and un-molted hens had higher (p<0.05) ovarian weights than hens on all other molted treatments. No significant differences (p>0.05) in ovarian weights were found among minerals supplemented groups A, B and C. The non-molted birds (group E) exhibited the greatest (p<0.05) feed intake over the 2 weeks molt whereas birds on minerals supplemented diets ate the least (p<0.05) feed. On average non-molted hens fed a balanced layer diet and molted hens fed without minerals diet had lower (p<0.05) egg production when compared with molted hens fed mineral added diets after 20 weeks post molt. However, molted hens fed without minerals diet had significantly higher egg production than that of non-molted hens fed a balanced layer diet. Egg shell quality and Haugh unit score improved (p<0.05) in molted hens compared to non-molted hens. Based on the results of this study, mineral feeding appears to be the best alternative to without mineral feeding in molting methods and yield comparable results. [Vet. World 2011; 4(9.000): 38
Black cumin seeds as phytogenic product in broiler diets and its effects on performance, blood constituents, immunity and caecal microbial population
Sohail H. Khan,Jehanzeb Ansari,Ahsan u. Haq,Ghulam Abbas
Italian Journal of Animal Science , 2012, DOI: 10.4081/ijas.2012.e77
Abstract: A study was conducted to evaluate the effect of 3 different levels (1.25, 2.5 or 5.0%) of black cumin seeds (BCS) on five hundred chicks. A basal diet was supplemented with either 0 (negative control), or 0.1% antibiotic (positive control), or 3 levels of BCS. At day 28 and 42 of age, the 2.5 and 5.0% BCS groups had significantly greater body weight gain (BWG) than the 1.25% BCS and the antibiotic group. The same groups had feed efficiency significantly improved (P<0.05) compared to the 1.25% BCS group and the controls. At both ages, measurement of the dressing percentage showed no marked variation between BCS supplementation and antibiotic. The 2.5 and 5.0% BCS groups showed an increase (P<0.05) in total protein and higher (P<0.05) haematological values than the 1.25%, antibiotic or unsupplemented diet group. The activities of blood enzymes were lower (P<0.05) and caecal coliform and Escherichia coli populations decreased (P<0.05) in BCS and antibiotic groups. Serum and tissue cholesterol concentration decreased (P<0.05) as the levels of BCS increased. The geometric means haemagglutination inhibition (HI) titres of the BCS and the antibiotic group were always higher than the negative control. The mean lymphoid organs weight/body weight ratio of the negative control was significantly (P<0.05) lower than BCS and antibiotic groups. In conclusion, including up to 2.5 or 5.0% BSC in the diets of broilers has no deleterious effects on their performance, immunity, serum biochemical constituents nor haematological indices. In fact, it may lead to the development of low-cholesterol chicken meat.

Ahmad Ansari Lari, Maryam Ansari, Soraya Ansari
Open Journal of Geology (OJG) , 2016, DOI: 10.4236/ojg.2016.66040
Abstract: As Iran is located on one of the two earthquake-prone belts in the world, and existence of faults and earthquakes is normal in Iran tableland. The main reason of earthquake is Neotectonic movements which can be effective in other natural disasters such as range movements. Due to the severe shortage of historical and seismic data and device in different parts of the world, particularly Iran, need for introducing more researchers and planners of Iran to tectonics and active tectonic areas is more visible. This study is an investigation of Neotectonic activities in Khafr basin area, Fars province. To achieve the aims of this study morphometric parameters were used. Investigations showed that severity and role of tectonic activities in different parts of the basin isdifferent, results of geomorphic and tectonic assessments indicate these differences.Stream length-gradient index (SL)on the main stream is inactive and sub streams are semi active, the ratio of the basin (BS)is 2.27, drainage basin asymmetry index (AF)is in semi active class, the ratio of width to depth of Valley (VF

Rashid M. Ansari, Yusra Ansari, Saiqaa Y. Ansari
Open Journal of Preventive Medicine (OJPM) , 2015, DOI: 10.4236/ojpm.2015.512052
Abstract: This article provides insight into the status of general practice in Pakistan and challenges to its health care system. The country ranked 122nd on the overall health system attainment and ranked 7th in the world on diabetes prevalence. The public sector health care system in Pakistan is encountered with many problems such as structural fragmentation, resource scarcity, inefficiency and lack of functional specificity, gender insensitivity and inaccessibility. The general practice status in Pakistan requires immediate attention to face the challenges created by chronic diseases in the country. Of particular mention are the patient-doctor interaction, healthcare system delivery, access to the doctors and better utilization of primary health care services.

Khawaja Jehanzeb,Anwar Rasheed,Mazen F. Rasheed
International Journal of Business and Management , 2013, DOI: 10.5539/ijbm.v8n8p79
Abstract: The purpose of this paper is to investigate impacts of training on organizational commitment and turnover intentions in private sector of Saudi Arabia. The study seeks to focus the relationship between organizational commitment and turnover intentions of the employees. A literature review of organizational commitment and employee turnover provides the basis for the research model and hypotheses. A self-administered questionnaire was used, involving 251 respondents from leading private organizations of Saudi Arabia to collect data and testing the existing theory. The results provide strong support for the hypothesis that is the negative relationship between organizational commitment and turnover intention. Employees’ training is significantly correlated with organizational commitment, turnover intentions and the commitment-turnover relationship.The sample was limited to private organization in Saudi Arabia. It may not be appropriate to generalize the findings across other populations or settings. However, the sample can be viewed as a representative case typical of many other organizations in the same industry. The results provides insight into the impact of organizational commitment on turnover intentions in the specific private sector of Saudi Arabia, which might benefit for managers and policy makers of the concerned organizations and in general for the whole sector. The paper studies the problems that exist in the private sector of Saudi Arabia.

Qurban Ali, Muhammad Ahsan and Jehanzeb Farooq
Electronic Journal of Plant Breeding , 2010,
Abstract: Eighty elite lines including ten standard varieties of chickpea were evaluated for various seedling parameters. Positive andsignificant genotypic and phenotypic correlations were found for different parameters like seedling length, root length,root/shoot ratio, seedling biomass, leaf length, leaf width and leaf area while root length was positively and significantlycorrelated with other parameters. Root/shoot ratio was positively and significantly correlated with all parameters. Seedlingbiomass had positive and significant genotypic and phenotypic correlations with all the parameters. Leaf length, leaf widthand leaf area also had positive and significant correlation among each other and with other parameters. The estimates of theheritability were high for seedling length, root length, moderate for the root/shoot ratio, seedling biomass and primary leafarea and slightly low for the primary leaf length and leaf width. Higher estimates of heritability and positive correlationcoefficients for seedling length, root length, seedling biomass, leaf length, leaf width and leaf area suggest that selection ofelite genotypes at seedling level might be effective for further breeding programme.
An Investigation of the Antecedents of Organizational Citizenship Behaviour: Case of Saudi Arabia
Anwar Rasheed,Khawaja Jehanzeb,Mazen F. Rasheed
International Journal of Psychological Studies , 2013, DOI: 10.5539/ijps.v5n1p128
Abstract: Organizational Citizenship Behaviour (OCB) has been signified as one of the antecedents of organizational effectiveness. OCB is widely studied over the years in the US but has received relatively inadequate attention in other Asian contexts. This study explored and examined number of predictors of OCB in the Arabic-speaking context (Saudi Arabia in Gulf). The data was drawn from 275 employees of both private and public banking sectors. Predictors of OCB examined are Job Satisfaction and Organizational Commitment, Role Perceptions, Fairness Perceptions, Leadership Behavior, Individual Dispositions, Motivation and Feedback. The results found support the hypotheses stating the positive relationship between the predictors of OCB and organizational citizenship behaviour except motivation that found no relationship with OCB. Implications for future research are discussed.
Offline handwritten signature identification using adaptive window positioning techniques
Ghazali Sulong,Anwar Yahy Ebrahim,Muhammad Jehanzeb
Computer Science , 2014,
Abstract: The paper presents to address this challenge, we have proposed the use of Adaptive Window Positioning technique which focuses on not just the meaning of the handwritten signature but also on the individuality of the writer. This innovative technique divides the handwritten signature into 13 small windows of size nxn(13x13).This size should be large enough to contain ample information about the style of the author and small enough to ensure a good identification performance.The process was tested with a GPDS data set containing 4870 signature samples from 90 different writers by comparing the robust features of the test signature with that of the user signature using an appropriate classifier. Experimental results reveal that adaptive window positioning technique proved to be the efficient and reliable method for accurate signature feature extraction for the identification of offline handwritten signatures.The contribution of this technique can be used to detect signatures signed under emotional duress.
An Efficient Combinatorial-Probabilistic Dual-Fusion Modification of Bernstein’s Polynomial Approximation Operator  [PDF]
Shanaz Ansari Wahid
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.212218
Abstract: The celebrated Weierstrass Approximation Theorem (1885) heralded intermittent interest in polynomial approximation, which continues unabated even as of today. The great Russian mathematician Bernstein, in 1912, not only provided an interesting proof of the Weierstrass’ theorem, but also displayed a sequence of the polynomials which approximate the given function . An efficient ‘Combinatorial-Probabilistic Dual-Fusion’ version of the modification of Bernstein’s Polynomial Operator is proposed. The potential of the aforesaid improvement is tried to be brought forth and illustrated through an empirical study, for which the function is assumed to be known in the sense of simulation.
A With-In Host Dengue Infection Model with Immune Response and Beddington-DeAngelis Incidence Rate  [PDF]
Hajar Ansari, Mahmoud Hesaaraki
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.32028
Abstract: A model of viral infection of monocytes population by dengue virus is formulated in a system of four ordinary differenttial equations. The model takes into account the immune response and the incidence rate of susceptible and free virus particle as Beddington-DeAngelis functional response. By constructing a block, the global stability of the unin-fected steady state is investigated. This steady state always exists. If this is the only steady state, then it is globally asymptotically stable. If any infected steady state exists, then uninfected steady state is unstable and one of the infected steady states is locally asymptotically stable. These different cases depend on the values of the basic reproduction ratio and the other parameters.
