Purpose Post marketing study is an ongoing process. In developed countries, it is one of most neglected phase of clinical trial. The current study was specially designed to assess the adverse drug reaction (ADRs) of Oral Salbutamol in chronic asthmatic patients at different clinical setups of Hyderabad, Pakistan. Methodology A cross-sectional study was conducted among 254 chronic asthmatic patients via purposive sampling method. The sample size was calculated on the basis of 5% of prevalence rate. Only those patients were enrolled who are on oral salbutamol (2 and 4mg Tablets). The confidence interval was 95%. The patients were enrolled from 10 different private clinical setups of Hyderabad, Pakistan. The data were analyzed using WHO assessment scale. Results Out of 254 patients, first group i.e. 154 patients were taken 2mg tablets and second group i.e.100 patients were on 4mg. Maximum ADRs were reported from second group i.e. 32 patients had developed various adverse reactions from minor to moderate. While 21 patients from first group had different adverse drug reactions. The most common ADRs were headache as minor ADR while tachycardia and arrhythmias were also reported as moderate ADRs. Mostly ADRs were reported in female as compared to male gender. The p value is less than 0.05. Based on WHO assessment scale, mostly ADRs were categorized in probable scale. Conclusion The Results revealed that on 4mg Salbutamol maximum number of ADRs were reported. There should be more focus to describe the underlying causes. Proper training will be utmost importance on reporting and dosing guidelines.

Changes in climatic variables at the sub-basins scale (having different features of land cover) are crucial for planning, development and designing of water resources infrastructure in the context of climate change. Accordingly, to explore the features of climate changes in sub-basins of the Source Region of Yellow River (SRYR), absolute changes and trends of temperature variables, maximum temperature (Tmax), minimum temperature (Tmin), mean temperature (Tavg) and diurnal temperature range (DTR), were analyzed annually and seasonally by using daily observed air temperature dataset from 1965 to 2014. Results showed that annual Tmax, Tmin and Tavg for the SRYR were experiencing warming trends respectively at the rate of 0.28, 0.36 and 0.31oC (10 yr)−1. In comparison with the 1st period (1965-1989), more absolute changes and trends towards increasing were observed during the 2nd period (1990-2014). Apart from Tangnaihai (a low altitude sub-basin), these increasing trends and changes seemed more significant in other basins with highest magnitude during winter. Among sub-basins the increasing trends were more dominant in Huangheyan compared to other sub-basins. The largest increase magnitude of Tmin, 1.24 and 1.18oC (10 yr)−1, occurred in high altitude sub-basins Jimai and Huangheyan, respectively, while the smallest increase magnitude of 0.23oC (10 yr)−1 occurred in a low altitude sub-basin Tangnaihai. The high elevation difference in Tangnaihai probably was the main reason for the less increase in the magnitude of Tmin. In the last decade, smaller magnitude of trend for all temperature variables signified the signal of cooling in the region. Overall, changes of temperature variables had significant spatial and seasonal variations. It implies that seasonal variations of runoff might be greater or different for each sub-basin.

Iqbal, Waheed,Jalil, Mudassar,Khadimallah, Mohamed A.,Hussain, Muzamal,Naeem, Muhammad N.,Al Naim, Abdullah F.,Tounsi, Abdelouahed Techno-Press 2021 Advances in nano research Vol.10 No.4
In present study, the numerical investigations are carried out for effects of suction and blowing on boundary layer slip flow of casson nano fluid along permeable stretching cylinder in an exponential manner. The modeled PDEs are changed into nonlinear ODEs through appropriate nonlinear transformations. Change in physical quantities like friction coefficient, Nusselt and Sherwood numbers with variation of the aforementioned parameters are also examined and their numerical values are listed in the form of tables. Effects of Reynold number, suction parameter, Prandtl number, Lewis number, Brownian motion parameter and thermophoresis parameter are seen graphically with temperature profile.

Iqbal, Waheed,Jalil, Mudassar,Qazaq, Amjad,Khadimallah, Mohamed A.,Naeem, Muhammad N.,Hussain, Muzamal,Mahmoud, S.R.,Ghandourah, E.,Tounsi, Abdelouahed Techno-Press 2021 Advances in nano research Vol.10 No.3
The present manuscript focuses the effects of suction on the flow of the dusty fluid along permeable exponentially stretching cylinder. Derived PDEs for this work are changed into ODEs by adopting right transformations. Numerical procedure is carried out for the obtained resultant equations by Shooting Technique in accordance with Runge-Kutta (RK-6) technique. Obtained results for the parameters namely, particle interaction parameter, suction parameter and Reynold number parameters are probed thoroughly. Some salient points are: (a) Fluid velocity decreases and the dust phase velocity rises for the higher values of particle interaction parameter; (b) more suction produces retarding velocities for both the phases; (c) high Reynold number slows down the fluid velocity while the speed of dust phase and (d) skin friction coefficient goes high for all these parameters.

The present manuscript focuses on the flow and heat transfer of the dusty fluid along exponentially stretching cylinder. Enormous attempts are made for fluid flow along cylinder but the study of fluid behavior along exponentially stretching cylinder is discussed lately. Using appropriate transformations, the governing partial differential equations are converted to non-dimensional ordinary differential equations. The transformed equations are solved numerically using Shooting technique with Runge-Kutta method. The influence of the physical parameters on the velocity and temperature profiles as well as the skin fraction coefficient and the local Nusselt number are examined in detail. The essential observations are as the fluid velocity decreases but temperature grows with rise in particle interaction parameter, and both the fluid velocity and temperature fall with increase in mass concentration parameter, Reynold number, Particle interaction parameter for temperature and the Prandtl number.
