Components of Valid Interrogation Techniques under Islamic Law

Valid interrogation of the accused is an art or skill in today’s modern world. The law and techniques of interrogation varies in the developed and developing world. Similarly, the Islamic law is not silent about the techniques of valid interrogation. There are specific rules and procedures for the interrogation of an accused either a criminal, an enemy, a spy or a war prisoner. This paper gives a detailed analysis about the principles and procedures of a valid interrogation process in Islam and its computability with the International Human Rights standards of interrogations. The paper argue that understanding the psychic-analytical niceties of interrogation helps an investigator to reach the truth. The paper finds that Islamic law gives full protection and safeguard to the rights of persons under custody and restrict the authorities to follow free and fair interrogation for ensuring justice. In this regard Islam presents a balanced view of the rights of the persons under custody and the executives exercise of legitimate force for interrogation. Islam strongly forbids torture and other inhuman ways of interrogation.

D Evelopment of a Gis Based a Lluvial Plain Conjunctive Use Contaminant Transport Model of Parts of D. I. K Han Using 3D Modeling Approach

The goal of this study was to develop a groundwater flow model and a contaminant transport model to understand the fate of the Arsenic in the groundwater. Visual MODFLOW 4.0, the Waterloo Hydrogeologic Inc. software was utilized for this study. A three-dimensional, finite- difference, groundwater flow model was used to develop a regional conceptualization of the flow system in the D. I. Khan area. The D. I. Khan sand aquifer system has been divided into three gently sloping geohydrologic units. The 2900 Km 2 study area was divided into 33852 cells with dimensions of 500 m by 500 m comprising of 186 columns and 182 rows and containing three layers. The finite difference block centered grid was used with an average depth of model simulation was set to 100 meters that almost equals to the average depth of existing tube wells (water wells). The model region was bounded by Indus River, Takwarrah Nala and the Sheikh Haider Zaman Nala in the east, northeast and southwest respectively. The area also consists of Gomal Nala, Chashma Right Bank Canal (CRBC) and Paharpur canal. The model was also adorned with the various hydraulic parameters spatial distributions including hydraulic conductivity (K), initial heads, recharge, porosity, specific storage (Ss), specific yield (Sy), top and bottom elevation of aquifers. The model was initially run for 10 years in steady state for the year 1985. In steady state a single time step was used. The model was calibrated with several runs by modifying the hydraulic conductivities and recharge values. The Parameter Estimation and Testing (PEST) has been used to do the calibration with the minimum and maximum ranges of 30 hydraulic conductivities and recharge values. The model was also calibrated in transient state in 1985 using steady state heads as initial conditions and assessing the draw downs. The area has been studied with respect to the various anthropogenic activities and found to be contaminated with high salinity, sulphates and Arsenic. The contaminant transport model MT3D was used with the observed Arsenic (As) concentrations and calibrated in 2010 for steady state and non steady state conditions. Model realizations were further projected up to 2025 to monitor the spreading of Arsenic concentration in the groundwater. The preliminary management scenarios were also discussed to address the issue at hand for safety of the inhabitants in the study area. The study results include estimates of hydraulic and transport properties, direction of regional flow, contaminant transport, its fate, prevention, remediation and a discussion of the iresults to gain a more complete understanding of the subsurface flow and contaminant transport system. Perhaps this work will be the first step in learning more about the subsurface flow system of the D. I. Khan aquifer, and provide a useful tool to manage and properly plan future management of the groundwater resources.
