The river sand group-A was applied to filter the wastewater under aerobic conditions of the experiments at lab scale. The filtration model was designed to filter water through gravity and suction flow process. The six attempts of sampling and analysis were conducted for 26 days from 7th May to 31st May 2018 at frequency of each attempt after one week of filter run. Filtered water flow rate was observed during both processes which were reduced gradually due to the clogging of filter bed. The reductions during gravity flow from 1.5 L/min to 0.31 L/min and by suction flow from 6.67 L/min to 3.33 L/min were observed during the six attempts of sampling and analysis. However, wastewater dosing rate was kept constant over the filter bed. The filtered water samples through both gravity and suction processes were analyzed to determine the concentrations of turbidity, total coliform, ammonia, nitrate and phosphate. The reduction in turbidity during gravity and suction filtration processes were in range from 99.6 to 95.9 % and 97.3 to 89.1 %. The total coliforms were reduced in the range from 93.3 to 96.2 % and 88.1 to 91.3 %. The ammonia concentrations were reduced in the range from 100 to 66.1 % and 97.9 to 70.8 %. The nitrate concentration reduced in the range from 100 to 70 % and 95 to 50 %. The phosphate reduction range was from 97 to 98.5 % and 66 to 89.6 % respectively.This study was conducted to understand the performance of riverbed sediments; river sand was taken from the downstream Kotri barrage for the preparation of filtration bed to treat the wastewater for the removal of bulk water pollutants.

The objective of this study work is to appraise the behavior of workers in Hala Gas Field of PPL. The evaluation is based on the critical behavior checklist in which total 1196 observations were carried out, 884 observations were found safe and 312 remarks as unsafe. The result indicates that proportion of unsafe act is 26.1% wherein using mobile phone and awkward posture are 18% and 15% respectively. Second objective of this work is to choose certain parameters like age factor, experience, safety behavior, job dissatisfaction, stress recognition and taking volunteer risk. All these parameters are statistically correlated with each other and it is found that job dissatisfaction is strongly correlated (around 70.5%) with taking volunteer risk. The impact of work stress or production pressure is 80.3% on risk taking behavior. This risky behavior certainly causes injuries which require mitigation by Behavioral Based Safety implementation.Work-related injuries are sharply increasing these days as of the high productivity demand.

It was generally perceived that the seawater effects could be decelerated by introducing supplementary cementitious materials (SCM) in concrete, which probably reduces its penetrability. Lower penetrability retains the aggressive slats out of the concrete, slows leaching of soluble materials such as lime, reduces the carbonation depth, and better corrosion protection to the reinforcement. Therefore, this study aims to evaluate the compressive strength performances of concrete with and without CBA exposed to seawater. In this study CBA was ground for 20 hours, to get particle fineness as comparable to the cement. Two types of concrete mixes were prepared; one is without ground CBA (M1) and another is with 10% of ground CBA (M2) as a SCM. Concrete cubes were prepared and immersed in normal water for 28 days, to get the desired strength. Afterward, samples were shifted in seawater. The specimens were evaluated for variation in compressive strength and change in weight under dual environments; normal water and seawater at 28, 56 and 90 days. It was experimentally determined that presence of CBA in concrete, raises the strength after 56 days. The strength of M2 concrete at 90 days, gives about 11.3% and 10.2% greater strength under normal water and seawater respectively as compared to M1 concrete. Hence, the CBA presence in concrete, reduces the penetration of aggressive salts, it is an indication of better durability performances of CBA concrete.

Indeed, Potwar is a geologically complex petroleum basin where petroleum exploration is tacky activity then a normal activity. Surface deformations, undulations and faults are very common in this basin due to surface uplift and continental- continental collision. Therefore, lineament study of geological structures in the basin provides us a way to find a more accurate and reliable approach to find hydrocarbon sites developed under the influence of subsurface geological pressure and plate tectonics. A complete set of bands provided by Landsat8 (OLI) is the most effective basic data by which lineament study is carried out with focus on visible bands and Panchromatic band due to spatial accuracy. Principal Component Analysis (PCA) provides us to find the most reliable PC having maximum spatial geological information. Lineaments are obtained using the most reliable component of the PCA. Lineament statistical analysis is performed to understand surface pressure points and orientation of geological structures present in the basin. Lineament map, lineament density map and lineament orientation map are produced to visually understand the layout of the area.
