4to (200 x 272 mm). 42, (2) pp. With 3 folding plates and several illustrations in the text, including 10 black-and-white photographic illustrations. Original printed wrappers. Rare geological paper presented at the 1972 Arab Petroleum Congress, issued by Dr. Soliman Mahmoud Soliman and Ezzat M. Korany, both professors of Geology at Ain Shams University in Cairo. It discusses the results of an extensive lithostratigraphic and petrologic study conducted in Jebel El Duwi, Qusseir area, the first of its kind, evaluating the area's suitability for petroleum prospecting. In this process the researchers collected samples of three rock formations for "deciphering the nature of the tectonic framework of sedimentation", drawing promising conclusions for sedimentary similar parts of Egypt with respect to petroleum prospecting. Images of rock samples, variation diagrams and lithostratigraphic logs back up their hypotheses and give an idea of the elaborate laboratory work necessary to carry out such a study. - In fine condition. - Cf.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Multi-band pass filters (BPF) and ultra wide band pass filters (UWB) have become the most important components to meet the requirements of wireless communication applications. This book develops multi band pass filters with small size without affecting its electrical performance. The particle swarm optimization algorithm (PSO) is used to optimize the filter parameters to design, and to improve the filter performance with regard to a given measurement of quality. Moreover, a compact tri-band pass filter is proposed using fractal structure to compact the size. Then the compact tri-band pass filters is designed with DGS to improve its performance and to eliminate higher order modes frequency to reduce the interference. After that the proposed tri-mode resonator is used to implement UWB-BPF with fixed and reconfigurable notch bands. Finally, the configurability is achieved by using PIN diodes due to their superior performance in wideband and high frequency applications. 128 pp. Englisch.…
