نجانے کس لیے
سحرِ حزیں،مسائے الم،شبِ ملُول،دلِ غمگیں
حسرتِ مسکیں،ادا س راہیں ،کھوئی کھوئی نگاہیں
بنا ہم سفر،نگر نگر دربدر
سانسیں بے قرار ،پا فگار
بے رنگ آسماں ،دھواں ہی دھواں
آرزئوں کے جال میں
حسرتِ وصال میں،گم کسی خیال میں،کسی کے ملال میں
بھیگی ہے آستیں، یارم نہیں قریں
ذاتی ملکیت میں کچھ آنسو،اس کا وجود نہیں جس کی جستجو
دلِ منتظر اداس ہے ،کوئی آس نہیں پھر...
No society is safe from crimes hence with the passage of time, crimes amplify along with alteration in its nature. As the approaches of investigation and finding the crime develop, the ratio of crimes also increases and the casualties occur with new devices and techniques. On the other hand individual and collective endeavors are being made to stop it. The concerned authorities try to finish or decrease these crimes by formulating various new rules. The rules that the Creator and the real Owner of the whole world had bestowed upon us in the form of Islam, it includes the right and basic techniques to control the crimes. As the modern technology has facilitated us with many facilities, it has also facilitated us in finding a culprit or proofs against him that helps in the stoppage of crimes and finding the criminals. As this modern technology has brought a great reduction in the casualties and crimes, on the other hand we have also to face some legal and Islamic issues. One of these issues is the case of medical test for witness that whether the test of clinical laboratory can be accepted as witness
Geographical Information System (GIS) is an emerging field of Environmental Science. Today with the rapid population growth and demand for more developments, the environmental issues are growing and resulting in more diversifying environmental problems especially pollution. This research reveals the importance of the spatial module of information which is a measure of the pollution data. In the present study, data of three years were managed, processed, evaluated and visualized by GIS and raster calculations. The results revealed the possible spatial relationship within environmental parameters and pollution. This thesis describes the broad range of geo-spatial modeling as well as some defies related to it. The objectives of the present study were to identify the spatial gradient pattern and distribution trend of fluoride pollution and its effect on the crops (wheat and maize) in vicinity of brick kilns (source of fluoride pollution) using geo-spatial and geo-statistical techniques. Besides statistical techniques were also employed to observe the distributional pattern using centrographic technique, identified the hotspots, the risk of pollution for nearby areas based on weighting distance interpolation technique and Kriging approach for more accurate estimation. Total 93 kilns were identified in Islamabad and three Tehsils of Rawalpindi, where wheat and maize crops were cultivated in the fields around the kilns. The sample number of plants and soil was 251 and 144 for summer and winter season respectively. More significant leaf injury to maize crop was observed in the summer compared to the wheat crop in winter. This observation was supported by Vegetation Index (VI), calculated by raster calculator. The results of chemical analysis indicated that fluoride concentrations (6.8 ppm, 14.3 ppm, 13.6 ppm, 13.9 ppm) were observed in the wheat plant samples of Jhangi syedan, Chakri, GT road, Mohra and maximum fluoride concentration (29.6 ppm, 29.45 ppm, 29.71 ppm, 29.41 ppm) was observed during the summer in maize plant samples of Bhatta road, Gurha, Dhok Niazu and Dhok Gujran in the year 2017. However, fluoride concentration in samples varied according to the spatial location with climatic condition. A dataset of Islamabad, Tehsil Rawalpindi, and Tehsil Gujarkhan showed significant positive spatial autocorrelation and clustering pattern, while no significant spatial correlation was found in the data set of Kallar syedan, but still significant hotspots were identified. A majority of hotspot for fluoride pollution was identified in the maize fields of Rawalpindi and Gujarkhan, in all study years. Furthermore, semivariogram based Kriging model indicated Islamabad, Northwest Rawalpindi, East Gujarkhan more at risk of fluoride pollution. Inverse distance weighting and Kriging Model also exhibited that effect on plants and soil gets reduced with increasing distance from the kiln. But the extent of the effect was only shown by the Ordinary Kriging Model. Climatic data marked temporal effect of fluoride variation in study areas during the study period. It was observed that high precipitation resulted into negligible fluoride effect and concentration, whereas less and no precipitation resulted into more fluoride effect and concentration. Similarly, positive correlation was found between temperature and fluoride pollution and effect. The effect of pollution was greater along distance at high temperature and effectively reduced by the distance in lesser temperature. It was necessary to screen out the current status of existing kilns and to evaluate the effect on nearby environmental parameters. Accordingly, this research highlighted the effect of fluoride pollution release from the kilns to soil and crops and revealed the spatial distribution pattern and extent of pollution using modeling technique.
