Safdar Husain Tahir, Muhammad Rizwan Ullah, Sajid Mahmood
American Journal of Industrial and Business Management (AJIBM) , 2015, DOI: 10.4236/ajibm.2015.55032
Abstract: This study investigates empirically the effect of dividend policy and investment decision on financing decision. To obtain the objectives, the data required, ranging from 2004 to 2013, were collected from the financial statements of all the banking firms listed in Karachi Stock exchange. Investment opportunity and actual investment were used as proxies of investment decision. Profitability and firm size were used as control variables. Multiple regression models were used to estimate the variables of interest. It was concluded that investment opportunity had significant effect on financing decision; however, the effects had no particular pattern. Furthermore, actual in-vestment and dividend policy had no impact on financing decision.

American Journal of Industrial and Business Management (AJIBM) , 2015, DOI: 10.4236/ajibm.2015.58056
Abstract: Bank credit plays an important role in the economy of any nation. The current study examined the association among bank credit to private sector and economic growth in Pakistan. Economic growth was taken as dependent variable, while bank credit to private sector, interest rate, inflation, investment to GDP and government consumptions were taken as independent variables. Secondary data were collected from World Bank Indicator, ranging for the period 1973 to 2013. Descriptive research and correlation were used to check the normality of data. Unit root test was used to check the stationarity of variables. Co-integration VECUM and Granger Casuality test were statistically used to test the variable relationship and casuality effect of the variable. Regression analysis was used to analyze the impact of bank credit on economic growth. The findings of the study showed that bank credit had extensive relationship with economic progression; in short term the relationship was also significant. Regression analysis showed that there was adverse impact of bank credit on economic growth in Pakistan. However, problem associated with bank credit facility is the constraint and regulation imposed by SBP on the percentage of credit to be given to the Entrepreneurs. For solitary in the meantime bank lending has a casual influence on economic growth, there is a policy need to give devotion to liberalization the monetary sector.

Noman Shabbir,Muhammad T. Sadiq,Hasnain Kashif,Rizwan Ullah
International Journal of Next-Generation Networks , 2011,
Abstract: This paper concerns about the radio propagation models used for the upcoming 4th Generation (4G) of cellular networks known as Long Term Evolution (LTE). The radio wave propagation model or path loss model plays a very significant role in planning of any wireless communication systems. In this paper, a comparison is made between different proposed radio propagation models that would be used for LTE, like Stanford University Interim (SUI) model, Okumura model, Hata COST 231 model, COST Walfisch-Ikegami & Ericsson 9999 model. The comparison is made using different terrains e.g. urban, suburban and rural area.SUI model shows the lowest path lost in all the terrains while COST 231 Hata model illustrates highest path loss in urban area and COST Walfisch-Ikegami model has highest path loss for suburban andrural environments.
Haplotype Analysis for DFNB4/PDS Locus in Hearing Impaired Families of Punjab (Pakistan)
Syed Babar Jamal,Zubair Anwar,Rizwan Ullah Khan,Talal Jamil
Current Research Journal of Biological Sciences , 2012,
Abstract: Deafness is one of the most common genetic disorders affecting 1 in 1000 newborns worldwide, while in Pakistan, its prevalence is 1.6/per1000.The present study was conducted to map reported autosomal recessive deafness locus DFNB4/PDS in highly consanguineous families in Punjab. For this purpose families with deafness were identified . Blood samples of these families were studied for linkage analysis of common reported deafness locus DFNB4/PDS. Genomic DNA was isolated from the blood samples of these families. Linkage analysis was then performed by amplifying microsatellite markers through PCR, Genotyping was done by ABI PRISM 3730 Genetic Analyzer. The Deaf Family was found linked to microsatellite markers of DFNB4/PDS. Linkages analysis showed that all three affected were homozygous for three STR markers for DFNB4/PDS while individuals V: 3 was heterozygous i.e., is carrier for DFNB4. Therefore individuals V: 3 were phenotypically normal but genotypically he is carrier. As the ages of that affected individuals’ ranges from three years to seven years they might develop goiter at a later age. Therefore at present this family is linked to an overlapping nonsyndromic/ syndromic locus DFNB4/PDS.

Aziz Khan, Fazal Munsif, Kashif Akhtar, Muhammad Zahir Afridi, Zahoor  , Zahoor Ahmad, Shah Fahad, Rizwan Ullah, Faheem Ahmed Khan, Mairaj Din
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.515246
Abstract:

Nitrogen (N) and Phosphorus (P) are of the most important and complex nutrients for the crop plants in particular for grain yield and quality. The field trials were laid out in randomized complete block design having three replications. Research trial plots were located at Agricultural Research Farm of Agricultural University Peshawar (Ameer Mohammad Khan Campus Mardan) during kharif season in 2012 to investigate the response of maize variety (Jalal) to three phosphorus rates (60, 90 and 120 kg·ha-1) and four nitrogen rates (90, 120, 150, 180 kg·ha-1) for agronomical traits. These traits investigated included number of plant per m2 (NP m2), plant height (PH), number of leaves plant-1 (NLP), leaf area plant-1·cm2 (LAP), fresh weight of plants kg·ha-1 (FW) and dry weight of plant kg·ha-1 (DW), were investigated. Results of the study showed that application of N @ 180 and P @ 120 kg·ha-1 significantly increased fodder yield of maize. The linear increase in biomass yield clearly indicated that N was a limiting nutrient factor and that N demand along with P has a positive response. At higher application rates, N fertilizer significantly

Pakistan Veterinary Journal , 2006,
Abstract: This study comprised of two experiments. The first experiment was aimed at determining progesterone concentrations in the blood samples collected from tail and jugular veins of pluriparous cyclic buffaloes. Plasma progesterone concentrations were 0.19 ± 0.36 and 0.12 ± 0.22 in early luteal phase (N=4) and 1.60 ± 0.72 and 1.35 ± 0.47 ng/ml in mid luteal phase (N=3) from tail and jugular veins, respectively. No difference (P>0.05) was found in progesterone concentrations in blood taken from the two sites. In the second experiment, cyclic or non-cyclic status of buffalo ovaries was determined by measuring plasma progesterone concentrations and palpation of ovaries per rectum. The reported anoestrous buffaloes (not showing heat symptoms for ≥ 6 months postpartum) were palpated rectally on two occasions, at eleven days interval, to monitor their ovarian activity. Blood samples were collected from jugular or tail vein. The buffaloes having no corpus luteum (N=3) on any ovary at both occasions were declared as true anoestrous, while those having a palpable corpus luteum (N=3) on one of the ovaries on any one occasion were termed as suboestrous. True anoestrous buffaloes had progesterone concentrations < 0.25 ng/ml on both occasions. The cyclic or suboestrous buffaloes had progesterone concentrations >1.0 ng/ml at one of the occasions. The results of this study indicated that progesterone concentration of blood plasma and rectal palpation of ovaries could be used for determining ovarian cyclicity in Nili-Ravi buffaloes.

Shafiq Ullah, Fiaz Ahmed, Amin Badshah, Ataf Ali Altaf, Ramsha Raza, Bhajan Lal, Rizwan Hussain
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0075999
Abstract: Nano materials with high surface area increase the kinetics and extent of the redox reactions, thus resulting in high power and energy densities. In this study high surface area zinc oxide nanorods have been synthesized by surfactant free ethylene glycol assisted solvothermal method. The nanorods thus prepared have diameters in the submicron range (300~500 nm) with high aspect ratio. They have uniform geometry and well aligned direction. These nanorods are characterized by XRD, SEM, Specific Surface Area Analysis, solubility in alkaline medium, EDX analysis and galvanostatic charge/discharge studies in Zn/AgO batteries. The prepared zinc oxide nanorods have low solubility in alkaline medium with higher structural stability, which imparts the improved cycle life stability to Zn/AgO cells.
