Survey and reproduction of computational approaches to dating of historical texts

Finding the year of writing for a historical text is of crucial importance to historical research. However, the year of original creation is rarely explicitly stated and must be inferred from the text content, historical records, and codicological clues. Given a transcribed text, machine learning has successfully been used to estimate the year of production. In this paper, we present an overview of several estimation approaches for historical text archives spanning from the 12th century until today.

Effect of Early Exposure of Dimethoate on Reproductive Potential in Swiss Male Mice

This study was done to evaluate reproductive potential of male mice following early exposure to dimethoate. Thirty-six Swiss albino male mice were divided into three groups of twelve mice each: first group injected intraperitoneally with distilled water, and used as a control group, while second and third groups injected with dimethoate at doses of 0.1 and 0.2 ml dimethoate/100 ml distilled water, respectively for 7 days. At the end of experiment, the mice were weighed and then were killed. Testis and epididymis weights were recorded, sperm parameters were evaluated.

Role of Mathematical Models in Epidemiology

The purpose of this research is to establish a suitable mathematical model for the study of epidemiology, showing the role of the epidemic threshold which cannot be distinguished from the data for use by infectious disease experts and public health. There has been a growing interest in recent epidemiological models of epidemiology because of their health and economic effects. Epidemiology (from a mathematical point of view) is a section of general epidemiology that deals with mathematical modeling in relation to the need to predict and spread infectious diseases.

Study of Morphometric gonads maturity stages and determination reproductive period for Saddled bream (Oblada melanura L.) in the coastal waters of Tartous

This study has been carried out on Saddled bream , from the family of Sparidae, which was caught from the coastal waters of Tartous province. The results showed that, Saddled bream reached at the fifth stage of sexual maturity during April and May for males and females, and the study of the sexual maturity index GSI confirmed these results.

The effect of some biological and genetic indicators of Scions on the success of grafting ceratoniasiliqua L. seedlings and on development of their subsequent growth

This research was carried out during 2014 - 2015 in Scientific Centre for Agricultural Researches. This research aims to determine the effect of some biological and genetic indicators on the success of Carob seedlings in nurseries by studying three kinds of grafting: Auto-grafting, Homo-grafting and Hetero-grafting. Rootstock aged one year and resulted by two chosen genetic types, namely, SnobarJablah and Alhafa were used. Scions, they were taken either from seedlings with age of one year resulted by these two types or from branches aged one year from the selected two types as well. Grafting was conducted by using Whip Graft way in spring. Auto-grafting has indicated the importance and the role of biological and genetic factors for grafts and their impact on rates of grafting success. Concerning rates of success, the results have shown that Auto-grafting surpassed Hetero-grafting with a significant reference for both of two genetic types, regardless if the used scion was young or old. In addition, Auto-grafting has shown surpass on other kinds of grafting, in terms of subsequent growth of scions. On the other hand, a variety in biological indicators values has been noticed between the two genetic studied types. In favour of SnobarJablahtype againstAlhafaʼs type. However, the differences of values were not significant for the most of conducted measures. As for the age of scions, the results have pointed out that values of Hetero-grafting with young scions surpassed values of Hetero-grafting with old scions in terms of the rate of grafting success and values of biological studied indicators.

The study of reproduction biology of gilthed seabream (Sparus aurata L.) in the Syrian Coast

This study has been done on Sparus aurata (Sparidae). Fish samples (297 individuals) were collected along the Syrian Coast from March 2012 to February 2014. Total length (T) was 15 - 31 cm, and the total weight (W) was 53,1 - 410,34 g. The study of gonado somatic index (GSI) showed that the reproduction period was between November and February with a maturity peak in January (3.98±0.97)% for females ,and in December (2.19±0.29)% for males. In addition, the length at the first sexual maturity was (21.5 cm) and (22.5 cm) for males and females respectively. The results of the hepato somatic index (HSI) was compatible with the surrounding environmental and physiological changes which resulted from the change of sexual activity during the reproductive cycle. Fecundity showed a wide range for a given length, there was a linear relationship between the absolute fecundity and each of length groups and total weight. Relative fecundity was (567896-849362) egg per 1kg body weight. The frequency distribution of eggs diameters revealed the presence of one peak, and the eggs diameter during the reproduction period ranged from 0.05 to 0.3mm.

Legitimacy extent of medical work in non-therapeutic cases

This research deals with Legitimacy extent of medical work in non-therapeutic cases such as virgin patching, sex change, medical sterility, lease of uterus for reproduction with medical assistance, plastic surgery and scientific research and experiments. The medical work is not legitimate in the previous cases, because it does not originally aim for therapy and cure, but it is possible that the medical work in the previous cases is legitimate if it is exceptionally aiming for therapy. The research concluded some results and recommendation, which may contribute in issuing required legal texts by the national legislator.

Resistance of Five Wheat Varieties to Khapra Beetle Trogoderma granarium Everts

This study aimed to compare the susceptibility of five wheat varieties Eratom, Al-Iz, Rabea, ACSAD and Om-Rabei to infestation by Khapra beetle by estimation of population density of insect phases, population reproduction rate and the loss in germination percentage at two levels of infestation 2 and 4 pairs/ 100 gr. grains and four storage periods 3, 6, 9 and 12 months under natural conditions. Results showed significant differences between varieties. Eratom was the most susceptible variety and the population density, population reproduction rate and loss in germination percentage were 2868.08 individual, 77.61 individual/month and 65.82%, while ACSAD was the least susceptible one and the values were 1004.91 individual, 23.88 individual/month and 47.49% respectively. Also infestation level and storage period had a significant effect on the population density, population reproduction rate and loss in germination percentage.
