Hydro-meteorological characteristics of Chitral River basin at the peak of the Hindukush range  [PDF]
Salma Khalid, Shafiq Ur Rehman, Syed Mushtaq Ali Shah, Alia Naz, Beena Saeed, Sadia Alam, Farman Ali, Hasina Gul
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.59120

This paper presents the impact of mean maximum temperature on Chitral river basin situated at Chitral district and high altitude (>6000 m) peaks of the Hindukush range under changing climate in Pakistan. The analysis of Chitral River as one of the tributary of Kabul River—the second largest river of Pakistan—revealed that change in temperature has a profound influence on the snow/glacial melt in comparison to the mean monthly rainfall. This is because the studied river is faded by the snow and glacial melt and receives a lot of snowfall from winter (DecFeb) to pre-monsoon (April-May). In monsoon period (Jul-Sep), 30% of the time the discharge rate remains above the mean while 60% of the time the discharge is less than the mean in the pre-monsoon (April-May) period. It means that 10% of the time the discharge is in reach of 300% to 900% of the mean flow, showing a rise in water yield and river discharge rate due to increase in mean monthly maximum temperature. Due to this significant increase (p < 0.05), the glaciers start melting faster and disappear in early summer, hence, reducing their residency period to convert into ice. This shows the signals of changing climate transfer into hydrological changes in Pakistan. Our findings are important for agriculture, hydropower and water management sectors for future planning especially in dry season for sustainable food security and for operation of ydrological installations in the country.

Tutorial Accounting Fundamentals: A New Look of British and American Accounting System  [PDF]
Nousheen Tariq Bhutta, Syed Zulfiqar Ali Shah
Open Journal of Accounting (OJAcct) , 2013, DOI: 10.4236/ojacct.2013.21004
Abstract: This paper aims to highlight the perception of graduate and undergraduate students regarding accounting fundamentals across British system and American system. The design of this paper is to derive a unique model which proves the both approaches are in same sense however, they are framed differently. Moreover, it provides a good justification of basic questions like why income and expense are treated as credit side and debit side of trading profit and lossaccount, respectively. Ultimately, it helps educators/instructors in influencing the perceptions of their students with regard to different accounting systems.

Investors’ Reaction to the Implementation of Corporate Governance Mechanisms  [PDF]
Nousheen Tariq Bhutta, Syed Zulfiqar Ali Shah
Open Journal of Accounting (OJAcct) , 2014, DOI: 10.4236/ojacct.2014.31002
Abstract: The study investigates the impact of corporate governance on investor reaction. This is the first study till date that addresses this gap in literature. The design of the study comprises of corporate governance, investor reaction. Data was taken from 125 non-financial sector of Pakistani companies listed at KSE for the period of 2005-2010. Data was extracted from balance sheet analysis (SBP report), KSE website and annual reports of companies. Correlation (individual and composite) and linear regression tests were applied to validate the outcomes. The results confirm that there is no impact of corporate governance on investor reaction and relationship between them is negative. This implies the inefficiency of financial market where noise trades create sentiment.
Study on the Estrous Cycle Regularity of Cryopreserved Rat Ovarian Tissues after Heterotopic Transplantation  [PDF]
Rumana Jafarey, Syed Ali Rehan Shah Jaffri
Open Journal of Obstetrics and Gynecology (OJOG) , 2016, DOI: 10.4236/ojog.2016.65037
Abstract: Objective: To evaluate the re-initiation of ovarian function in cryopreserved ovarian grafts by means of vaginal smear of transplant rats. Methods: A total of 40 SPF-SD female rats (5 - 6 week-old) were randomly divided into three groups (blank control, castration control and transplant group). Ovaries were removed by surgical procedure then after cryopreservation and thawing procedures the ovarian tissues pushed inside the back muscles gap in transplant group. On the first PO day, vaginal smear collection was daily initiated. After 30 days, the PO day when the estrous cycle was re-initiated was considered for analysis as well as the estrous days and the number of estrous cycles. Results: Normal control group had a regular estrous cycle, while the transplant group had an estrous cycle disorder within first 2 weeks and later 2 weeks after the transplantation while the duration of diestrus cycle lasted longer. At the same time, the castration group had lost the normal estrous cycle, keeping continue in the stage of diestrus. Conclusion: In transplanted animals the re-initiated ovarian function can be predicted with alteration between estrous and diestrus phases with predominant estrous irregularity. Moreover, short autotransplanted graft duration needs time to perfuse by new blood vessels and hormone secretions, so could not directly affect its target organs to function properly.
Re-Use of Hospital Plastic Waste in Asphalt Mixes as Partial Replacement of Coarse Aggregate  [PDF]
Syed Shahan Ali Shah, Rawid Khan
Open Journal of Civil Engineering (OJCE) , 2016, DOI: 10.4236/ojce.2016.63032
Abstract: About 1.3 billion tons of waste is being generated in the world annually. This waste is a cause of various diseases. Open dumping of waste also destroys valuable agricultural land. Various researchers have beneficially used plastic waste in cement concrete and asphalt concrete in the past. This study aims at the use of aggregates, made from different types of plastic waste, as partial replacement of coarse aggregates in asphalt mixes. For this purpose waste is collected from different hospitals of the city. Sorted plastic from the waste consists of 64% low density polyethene, 32% high density polyethene and 4% of polypropylene. Plastic waste is shredded, heated and after cooling, pulverizes manually and mechanically. Specific gravity of plastic aggregates is 0.96. Water absorption and soundness values are 4.68% and 7.68% respectively. Impact, crushing and Loss Angeles values of plastic aggregates are 0.7%, 0.5%, and 1.1% respectively. Replacement of natural aggregates by plastic aggregates in asphalt mixes is done up to 25% with 5% incremental increase. Density of asphalt mixes decreases to 2060 kg/m3. Consequently flow increases to 5.73 mm. Maximum stability is at 20% replacement i.e. 34.57 KN. Cost analysis of the study indicates that 205% increase in stability are observed with 219% increase in cost.
Convex Phillips Curve Explaining Openness and Inflation Nexus  [PDF]
S. Ali Shah Syed, Helène Syed Zwick
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.56086
Abstract: We study the theoretical nexus between inflation and trade openness in the presence of a non-linear Phillips curve. Phillips curve explains the inverse relationship between unemployment and inflation; however, the open economy macroeconomic models usually propose that the slope of the trade-off should be related to the extent of trade openness. The role of openness as a check on inflation has recently attracted attention of many [1]. The parallelism between the recent globalization wave and the fall in inflation has led to a perception that the determinants of the slowdown in inflation were not only the domestic ones but could partly be due to increased trade openness. This study describes this relationship considering a non-linear Phillips curve. Using the conventional Phillips curve approximated by Cobb-Douglas model we confirm the earlier observations regarding the existence of a significant impact of openness on inflation. The interesting contribution of this study is not only to establish the trade-openness and inflation nexus but also to identify the relevant channels through which openness impacts inflation. Our model predicts that in the current scenario of increased openness a non-linear symmetric loss function may still prevail, but for the policy purposes it necessitates to consider domestic and foreign propensities to import and the exchange rate sensitivity to inflation. In addition, the integration of the international markets would result into an even more important role of exchange rate dynamics as a response to the rising international trade. We find that in the presence of a convex Phillips curve any upward variation in the foreigners’ propensity to import would place a downward pressure on domestic inflation, provided that the current and the lagged rate of unemployment are less than minimum unemployment rate. Our model, while assessing the short run dynamics, also suggests that increased openness results into a complex divide among different economies, due to their sizes and structures. Investigating such a relationship as an extension of this study for different economic groups could reveal further interesting facts.
Oil Price Shocks and the US Stock Market: Slope Heterogeneity Analysis  [PDF]
Sarfaraz Ali Shah Syed, Hélène Syed Zwick
Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.63055
Abstract: This study investigates the oil and stock prices nexus in the US economy over the period 1980-2016. Using breakpoint regression technique, our findings are twofold: 1) we confirm the existence of the nexus as established in the existing literature on the subject; 2) while the relationship between the oil and stock prices remains intact, the slope changes over time, thus identifying a non-linear relationship.
The Professional Medical Journal , 2010,
Abstract: To compare the frequency of inflamed appendix in suspected patients of acute appendicitis having Modified AlvaradoScore (MAS) of 7 or more with patients having MAS of 6 or below. Design: Comparative cross sectional study. Place and duration of study:The study was carried out at Surgical Departments of Combined Military Hospital (CMH) and Military Hospital (MH) Rawalpindi from April 2006to April 2007. Material and Methods: This study involved 100 patients who were operated with provisional diagnosis of acute appendicitis.Preoperatively MAS of each patient was calculated and the patients were divided in two groups. Group-I had MAS of 7 or more while Group-IIhad MAS of 6 or below. Postoperatively appendices of all the patients were sent for histopathological examination and its result regardingpresence or absence of acute appendicitis was then compared with MAS of respective group. Results: (a) Group-I:- A total of 72 patients with64(88.9%) positive inflamed appendices on histology. Negative appendicectomy rate 8(11.1%), (b) Group-II:- A total of 28 patients with 8(28.6)positive inflamed appendices. Negative appendicectomy rate 20(71.4%). There is statistical significant difference of positive appendicectomyrate between two groups with (p-value<0.001). Conclusion: Frequency of inflamed appendix is more in patients having MAS of seven orabove. The number of negative appendicectomies can be reduced by using MAS in clinical practice.
Smith Normal Form of Matrices Associated with Differential Posets
Syed Waqar Ali Shah
Mathematics , 2015,
Abstract: We prove a conjecture of Miller and Reiner on the Smith Normal Form of the operator $DU_{n}$ associated with a differential poset under certain conditions. We do so by proving that the conjecture is equivalent to the existence of a certain decomposition of the $ \mathbb{Z}[x]$-module $ (\mathbb{Z}^{p_{n} }, DU_{n}) $, similar to the invariant factor decomposition of $ \mathbb{Q}[x]$-modules. We then use our result to verify the conjecture in certain special cases.
