Radiations made up of non-ionizing and ionizing radiations, this classification is based on the ionizing power and the energy of radiations. In developed and developing communities, people are continually exposed to radiations which are generated from variety sources that are naturally occurring or producing by human. The purpose of this study is to review accessible information on the influence of radiation on female fertility and to discuss the options for fertility preservation. Radiation exposure can result in impairment of tissue integrity and sometimes, leading to organs dysfunction, the impact of radiations on organs depends on site of irradiation, patient age and total radiation dose. Female patients who are treated with radiation have an increased rate of uterine dysfunction, ovaries dysfunction, impaired fertility, incidence of pregnancy complications, premature birth and miscarriage. Pre-pubertal uterus is more vulnerable to the effect of radiation, compared with the pubertal uterus due to arising ovarian estrogen production and uterus enlarges. To reduce the effects of radiations on female reproductive organ, fertility preservation procedures such as ovarian transposition, reproductive gland protection and oocyte cryopreservation should be carried out before and/or during radiotherapy.

The aim of the study is to demonstrate that infrared imaging can be used as a stand-alone phase in addition to health surveillance and medical evaluation. The advancement of infrared radiation techniques in the medical field in general, and breast cancer applications in particular, necessitates a review of this subject. The medical employ of thermography by infrared began in Germany shortly after 1950, where the single thermal picture of the individuals affected was shown long before (1928). Single Infrared radiation detectors were used at the outset. For a long time, thermal photography cameras soon taken from combat operations operation from low (thermal rather than spatial) resolution, and extraordinarily high product value. In addition, the decrease in laptop hardware value and software value putters. Since about 1980, better medical-suitable technology has been available hot thermocouple scale Fractional Preferential Attachment (FPA) processes have become more reachable, primarily LN2 cooled MCT scanners and then used widely after 2000, and have been widely used in medicine, despite some methodological concerns leading to medical misinterpretation. Individual medical thermal photography processes received certification in 2007, allowing them to be used as medical instruments for thermal measurement. Following European Health Regulations. Other instruments that do not have a CE health certificate are prohibited because photography is not allowed. Measurement functions that aren't used for temperature recording. Qualified medical infrared imaging can be used for a variety of purposes: rheumatology and orthopaedics, female breast region containing sensitive to thermal effort measures thermal radiation, neurology, cardiac photography (swing-libration vascular thrombosis), lab tests, surgical procedures, and completing body picturing.

             This work, which can be considered as a complement to our previous studies concerning chemical energy storage systems developing programmed, proposes the synthesis of new azo-Schiff bases derived from 1, 5-diaminoanthraquinone (DAAQ) resulting in an improvement in their absorption spectra. Five new derivatives (An1-An5) were synthesized by gentle fusing of (1 mmol of DAAQ) with (2 mmol) of early prepared azo derivatives of 2-hydroxy benzaldyhde. Medium to good yield was recorded on applying this method. Microwave irradiation of the same mixtures led to decomposition of the starting azo materials whereas prolonged reflux in DMSO was unproductive.

In this work,we give generalizations for the concepts essential submodule and uniform module.We call an R-submodule N of M semi-essential if N∩P≠0 for each nonzero prime R- submodule P of M, and we call an R- module M semi - uniform if every nonzero R-submodule N of M is semi-essential. Moreover, we generalize some properties of essential R-submodules to semi-essential R-submodules,and we generalize some properties of uniform R-modules to semi-uniform R-module. We also give conditions under them an R-submodule N of a multiplication R- module M becomes semi- essential. Furthermore, we give some conditions under them an R-module M satisfies ACC(DCC) on semi-essential R-submodules.

Kirkuk gas turbine power plant is supplied by the gaseous fuel from north gas company. The results showed that the theoretical efficiency of the unit is a function for two parameters; the compressor input temperature and the pressure ratio rp . So, the pressure rp ratio depends directly on the compressor input temperature. If the net work of the unit Wnet (Wt - Wc) is taken to be an index for the performance, the efficiency ƞ will be more in summer than that in winter because of the considerable reduction in compressor work Wc , while if the specific energy produced (or consumed specific fuel SFC) is taken as an index for the performance; the actual efficiency ƞac is more in winter since the specific energy produced in winter is greater approaching (4.5 kW.hr.m-3), while it did not exceed (2.8 kW.hr.m-3) in summer, this belong to the performance improving as the load increases approaching the design load, this is prevailing on the power plant operated by the diesel, heavy fuel or crude oil.

The Annual and monthly averages of rainfall and temperature of the tow tikrit and baiji meteorological stations showed that the general annual rainfall is (185) mm. The maximum rainfall is 35.5 mm in January and the minimum is (0.0) mm in august while the general monthly averages of temperature ranging between (8.7 C° in January - 36.5 C° in july ). After calculating the potential evapotranspiration values PE by thornthwait method then derive the values of water surplus WS in order to determined the amount of water that permeates to the groundwater level for each zone in the basin. After the main elements was selected depending by equations that has been developed for each zone as follows : 26 % of rainfall permeates to replenish the groundwater in the basin when the zone A lack o opportunity to allow infiltration of rainfall to the groundwater level for both A and B zones are based on monthly averages of whole surveillance period ( 1989 – 2009 ). The soil moisture amount (SM) is 25 mm for the zone A and 75 mm for each of A and B zones. When we search in the years that exceeds the general annual averages of rainfall ( 185 ) mm , founded that there are (9) years beyond the mentioned averages and account for about (43 %) of surveillance period where the general annual average equal to (242.39) mm and maximum monthly average of the rainfall is ( 41.86) mm in march and lowest average is (0.0) mm in july and august. Depending on these years mentioned, the water surplus for both zones C and B , showed that an increase about ( 29.93) mm from the average of annual rainfall equal to (242.39) mm and (12.34 %) from the rainfall permeates to fed the groundwater in B zone. 7 % adopted as a surface runoff from the rainfall equal to (16.96) mm and the ratio groundwater recharge in C zone is equal to (12.97 ) mm. The variation in groundwater values of recharge along the basin ( A,B and C ) is only a reflection for the type and texture of the deposits on the hand and varying depths, simple differences in topography and evolution of surface water drainage especially in the western part of C zone on the other hand . while the demonstrating convergence of inventories renewed values for the three zones although they have different area and water depths pervasive in all of them but the justification for this approach the increase in area of zones A , B and C, accompanied by decreasing values of deep water permeates for each zone must be noted here that the opportunity to renew stocks of ground water for both B and C amounting to 42 % of the prospect for renewed stocks of water in the zone A as well as the presence of large quantities of leaked water from the liquefaction and sewage water in zone A .
