The location of Iraq within the mid latitudes made it one of the places which receive large quantities of solar radiation. Due to the global trending of investing this energy and for environmental, healthy and economical considerations, there are great opportunities to construct projects that invest the solar energy to generate power in Iraq, which requires providing models specialized in locating the spatial and temporal distribution of the incident solar radiation on the inclined surfaces to provide more solar energy, In this study a mathematical program has been proposed by using MATLAP by using two kinds of models isotropic and an isotropic to locate the spatial and temporal distribution hourly solar radiation incident on inclined surfaces at latitude (25°- 40°) and longitude. (35°- 50°), considering the inclination angle is the optimum angle at all times. It shows the possibility of having more solar energy on the inclined surface compared with the horizontal surface; the difference was obvious in the months (January, February, March, October, November and December). The models mentioned above were also used in determining the spatial and temporal distribution of the incident solar radiation on the inclined surface under different sky conditions (clear, semi-cloudy and cloudy) above Iraq and the neighboring countries, it indicates that the difference in the solar energy between the three conditions is larger in January and December compared with other months.

Breast cancer is the most prevalent cancer among females all over the world. Breast self examination (BSE), mammography, and clinical breast examination are screening methods used to detect breast cancer early. The current research was carried out to assess the effect of breast self examination training program on knowledge and practice of adolescent girls. A quasi-experimental one group time series design was adopted in this research to achieve the stated aim. A Simple random sample of 135 adolescent girls was recruited. The research was conducted at the university student's hostel of Kafr elsheikh University. Two tools were constructed and filled in by the researchers: Structured interviewing tool; and Breast self examination checklist. Regarding total knowledge, pre-program 71.90% of adolescent girls have poor level of knowledge as compared to 97%, 100 % and 97.8% of them have high level of knowledge one month, three months and five months post program respectively. Concerning level of total practice, 100 % of adolescent girls showed unsatisfactory level of practice pre-program compared to 41.50%, 43.70%, and 54.10% of them have satisfactory level of practice one month, three months, and five months post program respectively. Moreover, after receiving the program 68.90% of adolescent girls practice BSE and 31.20% of them practice BSE regularly. In conclusion, knowledge and practice of adolescent girls were improved after receiving the training program suggesting its effectiveness. The study recommended that, adolescent girls should be equipped with health information related to BSE. As well, an emphasis should be done regarding to adolescent girls' healthy behavior pattern concerning BSE.

Assam, the only plain state amidst six hill states of Northeast India is endowed with as many as 5097 wetlands which size more than 2.25 hectares. Less than that size account 6081. The distribution, shape, size, depth, flora-fauna etc. of the wetlands in Assam are largely depend on the geo-ecological condition of the region and human activities in the peripheral areas. Keeping aside the rivers and streams the wetlands of the state have been classified into five categories depending on the shape characteristics. These are linear, compact, irregular, discrete (fragmented) and ox-bow wetlands. The shape characteristics speak many things about the origin, distribution and land use condition wetlands and it peripheries. Here, in this research the land use change in the peripheral areas of two wetlands viz. Urpad Beel and Deepor Beel, both falls almost in same ecological condition have been studies and compared based on satellite data of three different years 1977, 2007 and 2014 using GIS software supplemented by field observation. The impact of urbanization and changing pattern of land use in rural environment has been analyzed aiming at such study to be continued in other wetlands of Assam.

A Rapid, simple, precise and accurate reversed phase liquid chromatographic method has been developed and validated for the stability Indicating Assay for the combination Drug Lonsurf 20 mg trifluridine (FTD) / 9 mg tipiracil (TPI) in Bulk and Pharmaceutical Dosage Form. The chromatographic separation was achieved on a Kromasil (250 mm × 4.6 mm, 5 μm) analytical column. A mixture of potassium dihydrogen phosphate buffer and acetonitrile in a ratio of 30:70 (pH 2.5) was used as the mobile phase, at a flow rate of 1.0 mLmin-1 and detector wavelength at 240 nm. The retention time of Tipracil is 2.3min and for Trifluridine is 2.9min. The HPLC method was fully validated and the performance results of the proposed method were considerably satisfactory with reference to RSD values of validation parameters carried out for linearity, accuracy, precision, and robustness method precision and degradation studies. The linear dynamic range is from 50-300 ppm for trifluridine (FTD) / 22.5-135 ppm for tipiracil (TPI). The validated method was successfully applied to quantify the FTD and TPI in tablet form, and the corresponding recovery value was found to be 100.82 and 99.77% for both FTD and TPI. The developed method can be used for pharmaceutical dosage form and in process testing.
