Legal Status of Biobanks in the Contexts of Privacy Perception of Islamic Law

Development of Biotechnology has brought a feasibility of the scientific analysis on this biological data and the processing of personal data content within human biological materials. In this sense, it has been recognized as the main principle to protect the privacy of biological data belonging to individual since it can determine genetic makeup of an individual processing of personal data in the biological materials of human origin. Speaking of this context, Islam accepts human as the most dignified creation. This dignity given to human makes biological materials of human origin and human private. Privacy brings immunity. The responsibility to protect the human body has been given to mankind in order not to lose this dignity. This responsibility is not bounded by human＇s own body. It must protect the body privacy of next generation which is the heir of genetic heritage. This study will focus on the reflection of the privacy perception of the Islamic law towards body on the legality of human biological materials usage for research purposes.

Bamboo Winding Composite Utility Tunnels:a case study on mechanical behavior with WSN monitoring and numerical simulation

Bamboo Winding Composite Pipes(BWCPs)have many advantages such as good mechanical properties,low cost,low carbon,environmental friendliness,thermal insulation and easy installation et al.At present,BWCP is widely used in urban water supply,drainage,communication cable protection,farmland irrigation etc.It is obvious that the Bamboo Winding Composite materials have good application prospects in the field of utility tunnels.However,considering that the size of utility tunnels is much larger than that of normal pipelines,the wide application of Bamboo Composite Utility Tunnels(BCUTs)is still a challenge.In this paper,the force performance of BCUT in Datong Shanxi Province,was studied using two methods:real time monitoring and numerical simulation.Wireless sensor networks were used for monitoring,and the real time monitoring data of horizontal convergence and strains under the condition of backfill were obtained.The monitoring data indicated that the horizontal convergence can meet the requirement of relevant technical standards.A three-dimensional numerical model of the utility tunnel was established using FEM software.The influence of soil parameters on the deformation and strain of the BCUT was studied using the numerical method.The simulation results were compared with real-time monitoring data.The soil parameters K_(0) and k_(sh) have significant effects on the deformation,stress and strain of the utility tunnel.This kind of utility tunnel is recommended to use in areas with relatively good geological conditions.
