The present study is endeavored to study the oxidative stress and antioxidant response as well as the ultrastructural change of both liver and m.scle tissues of Siganus rivulatus collected from.polluted region (el-m.x Bay) and control region (m.rsa m.trouh) to identify the significance of biom.rkers. The results revealed that, el-m.x Bay was polluted by different types of chem.cals including hydrocarbons com.aring with the reference area (m.trouh area). Where, the concentration range of total hydrocarbons in sedim.nt sam.les collected from.m.trouh coast was 409.24 - 521.26 ng/g, dry weight, where as this range in sedim.nt sam.les collected from.el-m.xBay was 4159.77 - 4589.81 ng/g, dry weight. In this context, the induction of antioxidant system. in fish collected from.polluted area in response to oxidative stress should be considered as a clear indication of the presence of pollution and environm.ntal health degradation. Also, The increase in lipid peroxidation was a useful indicator of the pollution load in the present study. The results suggest that chem.cal pollution is capable of inducing m.rphological alteration in liver offish collected from.polluted area. The present study indicated that ultra-structural changes serveas biom.rker of stress in aquatic environm.nt.

The penetration of distributed generation (DG) in distribution power system.would affect the traditional fault current level and characteristics. Consequently, the traditional protection arrangem.nts developed in distribution utilities are difficult in coordination. Also, the reclosing schem. would be affected. With the rapid developm.nts in distribution system.autom.tion and com.unication technology, the protection coordination and reclosing schem. based on inform.tion exchange for distribution power system.can be realized flexibly. This paper proposes a m.lti-agent based schem. for fault diagnosis in power distribution networks with distributed generators. The relay agents are located such that the distribution network is divided into several sections. The relay agents m.asure the bus currents at which they are located such that it can detect and classify the fault, and determ.ne the fault location. The proposed technique uses the entropy of wavelet coefficients of the m.asured bus currents. The perform.nce of the proposed protection schem. is tested through sim.lation of two system.. The first system.is a benchm.rk m.dium.voltage (m.) distribution system.and the second system.is practical 66 kV system.of the city of Alexandria.

This paper proposes a m.lti-objective index-based approach to optim.lly determ.ne the size and location of m.lti-distributed generators (DG) units in distribution system.with different load m.dels. It is shown that load m.dels can significantly affect the optim.l location and sizing of DG resources in distribution system.. The proposed m.lti-objective function to be optim.zed includes a short circuit level param.ter to represent the protective device requirem.nts. The proposed function also considers a wide range of technical issues such as active and reactive power losses of the system. the voltage profile, the line loading and the m.A intake by the grid. The optim.zation technique based on particle swarm.optim.zation (PSO) is introduced. The analysis of continuation power flow to determ.ne the effect of DG units on the m.st sensitive buses to voltage collapse is carried out. The proposed algorithm.is tested using the 38-bus radial system.and the IEEE 30-bus m.shed system. The results show the effectiveness of the proposed algorithm.

Distance protection of transm.ssion lines including advanced flexible AC transm.ssion system.(FACTS) de-vices has been a very challenging task. FACTS devices of interest in this paper are static synchronous series com.ensators (SSSC) and unified power flow controller (UPFC). In this paper, a new algorithm.is proposed to detect and classify the fault and identify the fault position in a transm.ssion line with respect to a FACTS device placed in the m.dpoint of the transm.ssion line. Discrete wavelet transform.tion and wavelet entropy calculations are used to analyze during fault current and voltage signals of the com.ensated transm.ssion line. The proposed algorithm.is very sim.le and accurate in fault detection and classification. A variety of fault cases and sim.lation results are introduced to show the effectiveness of such algorithm.

Groundwater is an im.ortant source of freshwater for drinking and irrigation purposes, and hence protecting it against depletion and deterioration is extrem.ly required. Groundwater could get contam.nated physically, chem.cally, or m.crobiologically. Each type of contam.nation is linked to different sources and in turn im.oses different types of health problem. and consequences. A water sam.le from.Bahr Al-Baqar Wastewater drain and 13 groundwater sam.les were collected for physiochem.cal and bacteriological analyses to evaluate groundwater contam.nation in As-Salihiyyah and adjacent areas, east of Nile Delta of Egypt. Nitrate, COD, and BOD values collected from.Bahr Al-Baqr drain and groundwater exceeded the Egyptian m.xim.m.perm.ssible lim.t for drinking water (0.5, 6, 10, respectively). The total num.er of viable m.croorganism. (TVC) test for Bahr Al-Baqar drain was recorded as m.re than 300 CFU/m., and the total coliform.recorded 1100 m.N/100m., indicating high level of contam.nation. The high count of the TVC (16-↑300 CFU/m.) for groundwater and the total coliform.(3 - 1100 m.N/100m.) indicated that groundwater is contam.nated and unsafe for drinking and m.ght be affected by Bahr Al-Baqar wastewater drain.
