This book aims to define the ecological aspects (soil conditions and factors affecting seed germination) of some selected parasitic flowering plants e.g. Cuscuta and Orobanche. The host-parasite interactions among some flowering plants will be discussed. Soil salinity was found to be an important factor controlling the distribution of parasites. However, Cistanche was found to be less sensitive to soil salinity as indicated by its ability to infect plants living in soil with relatively high salinity. Other soil chemical properties (such as calcium and magnesium contents) played a marginal...

Currently working as professor of Ecology at Damietta University. He published more than 100 research papers in national and international journals. He is interested in plant diversity and management of natural resources. Ecology of medicinal herbs of Egypt in response to stress and the diurnal regulation of photosynthesis in relation to water budget (water management strategies). The roles of the transcription factors in the regulation of...

Phasor measurement units (PMUs) are considered as a promising tool for future monitoring, protection and control of power systems. One of the applications of phasor measurements is state estimation. The first step in state estimation is to gather measured data from different substations in a power network. These measurements must be sufficient to make the system observable. This book adopts three algorithms for minimizing the size of the PMU configuration while allowing full observability of the network; Depth First Search (DFS), Simulated Annealing (SA) and Minimum Spanning Tree (MST)...
