A review of the state-of-the-art in aerodynamic performance of horizontal axis wind turbine
Luhur, Muhammad Ramzan,Manganhar, Abdul Latif,Solangi, K.H.,Jakhrani, Abdul Qayoom,Mukwana, Kishan Chand,Samo, Saleem Raza Techno-Press 2016 Wind and Structures, An International Journal (WAS Vol.22 No.1
The paper presents the state-of-the-art in aerodynamic performance of the modern horizontal axis wind turbine. The study examines the different complexities involved with wind turbine blade aerodynamic performance in open atmosphere and turbine wakes, and highlights the issues which require further investigations. Additionally, the latest concept of smart blades and frequently used wind turbine design analysis tools have also been discussed. The investigation made through this literature survey shows significant progress towards wind turbine aerodynamic performance improvements in general. However, still there are several parameters whose behavior and specific role in regulating the performance of the blades is yet to be elucidated clearly; in particular, the wind turbulence, rotational effects, coupled effect of turbulence and rotation, extreme wind events, formation and life time of the wakes.

Evaluation and future predictions of air pollutants level in Karachi city
Mukwana, Kishan Chand,Samo, Saleem Raza,Jakhrani, Abdul Qayoom,Tunio, Muhammad Mureed,Jatoi, Abdul Rehman Techno-Press 2017 Advances in environmental research Vol.6 No.2
The purpose of this study was to determine the present air pollutant concentrations and predicted levels for next 30 years in urban environment of Karachi city. For that, a total of fifty measurements were made for each twenty selected locations of the city. The locations were selected on the basis of land use pattern such as residential, commercial, industrial settlements, open areas, congested traffic and low traffic areas for investigation of air pollutants variability and intensity. The measurements were taken continuously for six months period using PM Meter, Model AEROCET 531 and Ambient Air Quality Meter, Model AAQ 7545. The concentration of air pollutants were found higher at Al Asif Square and Maripur Road due to higher intensity of traffic and at Korangi Crossing because of industrial areas. The level of pollutants was lower at Sea View owing to lower traffic congestion and transportation of pollutants by sea breezes.
