Effect of Freezing On Some Morphometric Features of Planiliza Abu ( Hekel,1843)
...Show More Authors

The present study attempts to determine the effect of freezing for different periods on preserved bodies of fish in the laboratory to keep for the research and diagnosis of taxonomic studies and not for consumption. It also endeavors to identify the effect of freezing on some morphometric features of the preserved bodies of fishes. Planiliza abu fish were used to conduct the present study. Fish were frozen by regular freezing in the home refrigerator freezer with temperatures reaching four degrees centigrade below zero. Freezing time is distributed over four months; biometric measurements of frozen fish have been taken in these periods represented by body total length, Standard length, and Head length in centimeters using a ruler vernier caliper in addition to body weight in grams by using a scale. Statistical data analysis for this experiment has been conducted to investigate the resulting facts of freezing periods and the effect of differences in freezing periods on these biometric measurements using Duncan's new multiple range test and Levene's test. Results showed no apparent significant differences related to the size in total length and standard length and weight, While measuring head length showed important characteristics of frozen fish, especially in the first and third month of the experiment. Most of the sources that deal with such research patterns are concerned with the freezing of fish intended for food and human consumption, and few of these studies are concerned with research freezing, such as preserving frozen fish specimens for analysis, even for some time. Attention to the importance of freezing for research studies related to fish because of the susceptibility of its meat to rapid deterioration, and therefore, may give wrong diagnostic results if the survey is between species from the same family or a diagnostic and taxonomic study between many species belonging to different families. Keywords: Body measurements, Coastal fish, External appearance, Ice crystals, Preservation.

The Effect of a Suggested Translation Strategy on ESP Learners’ Achievement in Translation
...Show More Authors

In spite of the disappearing of a clear uniform textbook for teaching ESP at different departments and different colleges in both scientific and humanistic studies, the practitioners at those departments and colleges have to teach translation as one of the important requirements to pass the English language exam. The lack of defined translation activities is a noticeable problem therefore; the problem of teaching translation is diagnosed in that the students lack the ability to comprehend the text in English language and other translation knowledge and skills.

The study aims to suggest a translation strategy and then find out the effect of the translation strategy on ESP learners’ achievement in translation. A sample of 50 stud

Experimental and Simulation for the Effect of Partial Shading on Solar Panel Performance
...Show More Authors

Partial shading is one of the problems that affects the power production and the efficiency of photovoltaic module. A series of experimental work have been done of partial shading of   monocrystalline PV module; 50W, Isc: 3.1A, Voc: 22V with 36 cells in series is achieved. Non-linear power output responses of the module are observed by applying various cases of partial shading (vertical and horizontal shading of solar cells in the module). Shading a single cell (corner cell) has the greatest impact on output energy. Horizontal shading or vertical shading reduced the power from 41W to 18W at constant solar radiation 1000W/m2 and steady state condition. Vertical blocking a column

The linguistic meaning of the verse in the Arabic dictionaries applies very much to the reality of rent and its effect. This is true of economic growth as a continuous increase in real per capita income in addition to the same thing. Therefore, development does not necessarily achieve a comprehensive and structural increase of the various economic sectors. As the rent came in the sense of a terrible land open Maim any fertilized. And the camel is a ma'aya and a ra'i: that is, it goes in the pasture and returns itself. This is similar to the extraction of oil after it is ready for investment and earn its revenue as soon as it exists or is extracted by external parties. If the rent is first linked to agriculture, especially the fertile lan
