Millet and Sorghum are grown as the main staple food crops for millions of people in the rural and urban areas in Sudan. Their production is not enough to fill the food gaps, which widening in intervals. This book is to investigate the farming system, the factors affecting food grain production and to analyze the resource allocation. The cross-sectional data collected from stratified random sample of 192 farmers. Cobb-Douglas production functi...

Der Weg einer jungen Frau aus der Gefangenschaft des ISBadeeah Ahmed Hassan war gerade einmal 18, als IS-Kämpfer ihr Dorf im Irak überfielen. Mit Hunderten anderer jesidischer Frauen und Mädchen wurde sie verschleppt und nach Syrien verkauft. Dort landete sie als Haussklavin bei einem hochrangigen IS-Kämpfer in Aleppo. Sie wurde regelmäßig misshandelt. In Monaten der Gefangenschaft waren es die Erinnerungen und Geschichten aus ihrer Kindheit, ...

This work aimed to study the conversion of different types of plastic waste to liquid fuel oil by thermal and catalytic pyrolysis using bentonite and alumina as a catalyst in a laboratory scale semi-batch reactor. The pyrolysis of different types of plastic waste was carried out and optimum conditions were evaluated by changing various parameters such as pyrolysis temperature from 490°C to 550°C, using different types of catalyst such as bento...

The Middle Eocene limestone succession (of Lutetian age) exposed at the area extends along the Western side of Gulf of Suez to the south western scarp of Gabel Ataqa, including Gabel Kahylia to the north and Gabel Okheider to the south, is differentiated from base to top into: Minia Formation and Mokattam Formation. The detailed petrographic analyses of 170 samples taken from two measured, stratigraphic sections in the study area, have led to ...

Medical uses of ultrasound came about shortly after the close of World War II, derived from underwater sonar research. Initial clinical applications monitored changes in the propagation of pulses through the brain to detect intacerebral hematoma and brain tumors based on the displacement of the midline. Ultrasound rapidly progressed through the 1960s from simple "A-mode" scans to "B-mode" application and compound "B-mode" images using analog e...

This study includes the determination of Trifluoperazine hydrochloride (TFPH) and Tetracaine hydrochloride (TCH) drugs by conventional ion-selective electrode (ISE) and flow injection potentiometry (FIP). Chapter one describe general introduction about ISE and FIP with review of its applications in pharmaceutical analysis. While chapter two describe chemicals, apparatus, preparation of standard solutions, and construction of membrane electrode...

This work introduce four chapters, chapter one include the weed ecology, its classification and pictures of some weeds. Chapter two contains some non-traditional methods of weed control such as mulching, solarization, irrigation systems, herbicides-fertilizer interaction and biological control. Chapter three involves weed control in some horticulture orchards and crops and the last chapter is references. The aim of this work, raising the stand...

During the past three decades, there have been considerable advances in the prevention, diagnosis and treatment of craniomaxillofacial (CMF) injuries. Preventive legislation (speed limits, alcohol restriction, use of helmets, shoulder and seat restraints), improved road construction measures and vehicle safety modifications (safety glass, padded dash boards, stronger frames, collapsible steering columns, airbags) have led to a significant decr...

Cancer is the second leading cause of death in the world after cardiovascular diseases. Today, millions of cancer people extend their life due to early identification and treatment. Breast cancer is one of the most common and serious malignancies worldwide. Despite intensive cancer control efforts, it remains the second-leading cause of cancer death among women. MCF-7 cells are useful for in vitro breast cancer studies because the cell line ha...

This study was conducted to evaluate the percentage of calcium concentration in bones, utilising bovine leg and rib bones. The Nd:YAG pulsed laser (1064 nm) was used to generate plasma from experimental alloys and bones. Three combinations of calcium/lead alloys were made up in order to create calibration (standard) curve. The concentrations of calcium-lead in the experimental alloys were 0.01g:5.99g, 0.1g:5.9g and 1g:5g respectively. The calc...

This book represents an integrated geophysical study for the farafra area, Western desert, Egypt including a general review for the different geological data and studies carried out over this area, followed by the petrophysical analysis for Ammonite-1 well which is the nearest well for this area, then the interpretation of the allowed seismic reflection data by picking of four different sequence boundaries and ting them with the well data, fin...

Occupational hazards are defined as risks to people usually arising out of their employment. Cardiac catheterization was the step to using the technology in the sciences its procedure used for diagnosing and treating multi heart problems.Work in the cardiac catheterization unit needs to take precaution and applying safety measures and precaution in professions to prevent any hazards or injury. The source of hazards is the work environment, whi...

In this book, The powerful capabilities of tuning PID and FLC controllers based on Genetic Algorithm (GA) in locating the optimal solutions to a given optimization problem are exploited by determining the controller parameters of the PID and FLC controllers in order to meet specified performance objectives. The performance of the fire tube boiler that fitted with GPID and GFLC has reliable dynamic performance as compared with the system fitted...

Centrifugal pumps are probably among the most often used machinery in industrial facilities as well as in common practice. After developing the computers and the CFD software, the numerical simulation of a centrifugal pump becomes very powerful tool to predict its performance. Nowadays using CFD technique to predict centrifugal pump performance save money and experimental efforts compared with the old techniques in centrifugal pump design. In ...

Aromatic plants contain odorous, volatile, hydrophobic and highly concentrated compounds called essential oils (or volatile). Leaves, fruits and roots, essential oils are complex agriculture mixtures of secondary metabolites consisting of low-boiling point phenylpropenes and terpenes. There are more than 3000 plants used for their essential oils of which about 300 are used commercially as flavors and fragrances. The food industry uses the oils...
