Publisher : Universitas Pendidikan Indonesia (UPI)

Self-generated earthquake catalogue of Mw≥6.0 upto 300 km depth was prepared for the inversion of six components of moment tensor. Seismotectonic map was drawn with seismicity distribution. The stress map of Pakistan was generated through CASMO which described by the Anderson model (1951). The maximum horizontal stress (SHmax) acting in the compressional zone generates reverse faulting (RF) causes to form the three distressing mountainous range called Karakorum, Hindukush and Himalayan i-e SHmaxSHmin. In eastern side of Pakistan, minimum horizontal stress (SHmin) acting in the extensional zone produced normal fault (NF) i-e SHmax SHmin. Focal mechanism was also drawn using source parameters of each event obtained by matlab codes. Stress tensor components were obtained using mathematical equations and out comes were written in the form of 3x3 matrix. All matrices have non trivial solutions and their solution sets were also evaluated in the form of eigen values and eigen vectors. Crustal thickness was displayed by thickness map. The maximum thickness of curst in northern Pakistan i-e 60-70 km whereas in southwestern region this varied from 20– 40 km all around. This variation due to plate motion intensity and velocity of Indian and Eurasian plate collision.

Continuous increase in population has resulted in increased demand for building material. Bricks are the major building material and are a fast-growing industrial sector in many countries such as Pakistan, China, India, and Bangladesh. Despite its integral role, it is among the top three factors that cause the emission of harmful pollutants that not only affect our climate and human health but also effecting agriculture sectors to a great extent. Brick kilns emit gases like SO2, CO, Black Carbon, CO2, NOx, PM, etc., that affect our biotic and abiotic components of the ecosystem. So, the objective of this paper is twofold. Firstly, it has been focused on the pollutants emissions from brick kilns, their effects on climate and agriculture sectors. Secondly, the possible techniques have been discussed that can be used to reduce or eliminate its harmful impacts. It was found that the pollutant emissions from brick kilns like SOx, NOx, CO2, CO, unburnt hydrocarbons, Particulate matter, heavy metal, and various other compounds have a significant effect on the surrounding environment, climate and agriculture field in the vicinity of brick kilns. If the proper technology for reducing pollutants will not be installed in the brick kiln, there might be a serious disadvantage of climate and especially in the agriculture field in the vicinity of brick kilns.

Portland Pozzolana Cement (PPC) is prepared by adding Pozzolanic materials to ordinary Portland Cement. The artificial pozzolana materials used in the manufacturing of PPC such as fly ash, silica fume, rice husk, blast furnace slag, are actually industrial waste, which is produced in large amounts. These artificial pozzolana materials when used in concrete can reduce consumption of natural resources, diminish the effect of pollutants in the environment and it is economical and reliable. The main objective of this paper is to focus on the properties and applications of Portland Pozzolana Cement and make effective use of different industrial by-products in the manufacturing of cement. We found that both PPC and ordinary portland cement (OPC) are commonly used types of cement in construction. Nowadays, PPC is used as a substitute for ordinary Portland cement (OPC cement). Since PPC contains pozzolanic materials, it helps to enhance the strength of concrete. The quantity of PPC required in making the concrete is less when compared to OPC. PPC is a green material that contributes towards sustainable development.

This study generally aimed to determine the effectiveness of kamias, star fruit, and karamay fruit extracts in removing stains. Previous studies revealed the effectiveness of Kamias as a stain remover, while, this study compared the effectiveness of different fruit extracts as a stain remover and the potential utilization of other fruit extracts from trees that are locally available. We determined the cost of making stain remover using kamias, karamay, and star fruit extracts, the ability of these fruit extracts as a stain remover in terms of the degree of strain reduction and whitening of the cloth, and ultimately, the significant difference between the various treatments. Results revealed that the use of star fruit extract was the cheapest among the four treatments while the highest cost was incurred using Karamay extract. There was a significant difference observed between treatments. Bleach was the most effective in removing the stains and whitening the fabric, followed by the kamias extract. In terms of removing stains, whitening the cloth, and availability in the neighborhood, the extract was found to have the best results. We, therefore, recommended the use of kamias extract as an alternative organic stain remover for fabrics and be used by the households. Being derived from natural fruit extract and contain no dangerous chemicals, the product is safe for human use and environment-friendly.
