Research ArticleOpen accessIn the abstractLow Power Phase Locked Loop Frequency Synthesizer for 2.4 GHz Band ZigbeeNesreen Mahmoud Hammam Ismail, Masuri OthmanProblem statement: Wireless communication systems are required for many applications. There are different standards for these systems. IEEE 802.15.4 defines the communication system standard for zigbee. This study discussed designing one of the blocks of zigbee transceiver which is the Phase Locked Loop (PLL). A major target for any communication systems is saving battery power, especially for zigbee as it … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,061 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUse of 2D Multi Electrodes Resistivity Imagining for Sinkholes Hazard Assessment along the Eastern Part of the Dead Sea, JordanAbdallah S. Al-Zoubi, Abd El-Rahman A. Abueladas, Rami I. Al-Rzouq et al.Sinkholes and subsidence are natural phenomena can be occurred in shallow geology sediments at different regions in the world. Sinkholes assessment is one of the most difficult near subsurface investigations. Geophysical prospecting is appropriate method to determine environmental and geotechnical problems. 2D multi electrodes resistivity imagining with Wenner-Schulmberge array was conducted within active sinkholes area. The objective of the survey … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,057 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of the Efficacy of Entolek K Planteco® Biopesticide Based on Akanthomyces Lecanii Fungus Against Pest Orthopterans in Soybean Agroecosystems in Southeast KazakhstanIzbasar Temreshev, Askhat Tursynkulov, Yerlan Dutbayev et al.Pest control services dealing with mass pests such as locusts and grasshoppers are forced to use insecticides of various origins to prevent crop damage. In most cases, mainly chemical insecticides are used. This method of regulating pest populations has many negative consequences. As a result of chemical treatments with broad-spectrum insecticides, not only pests are killed, but also non–target organisms,primarily … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 25 Nov 2022 · 5,217 accessesView PDF Cite
