Three crosses of upland cotton were carried out between SP8886 and each of the varieties, Lachata, Cocker310 and Dunn1047, and F1, F2, B1 and B2 generations of each cross were obtained. The six generations of each cross were tested in an experiment using randomized complete block design with three replications to study the genetic behavior for seed cotton yield per plant and some of its components. Generation mean analysis (least square method) was used with two models to estimate additive, dominance and epistatic effects, the first with three parameters (additive-dominance model) and the second with six parameters (additive-dominance-interaction model), and χ2 – test used to determine the fitness of the first model for characters: seed cotton yield per plant, plant height, number of fruiting branches, number of bolls per plant, boll weight and lint index. The results showed that the first model was adequate for most of the studied characters in the three crosses, therefore epistasis was not important in the inheritance of these characters except plant height in the cross (Lachata x SP8886) and seed cotton yield per plant in the cross (Cocker310 x SP8886). Dominance gene effects were relatively more important than additive effects in the inheritance of the most of studied characters. Narrow sense heritability estimates were varied from 17.441% for seed cotton yield per plant in the cross (Cocker310 x SP8886) to 69.999% for number of fruiting branches in the cross (Lachata x SP8886). The results also revealed the presence of positive heterosis and inbreeding coefficient for the most of the studied characters in the three crosses.

A study was completed to compare flow parameters over a modified ogee-crested spillway which represent an existing project (Al-Dhuloyia Spillway) using a physical model and existing literature. The physical model was constructed by wood with smoothness surface and placed in a test flume. Pressure taps were installed along the entire length of the spillway. Discharge and pressure data were recorded for 10 different flow conditions. Data interpolated from U.S. Bureau of Reclamation and U.S. Army Corps of Engineers design monographs provided discharge and pressure data from the literature. Non dimensional discharge curves are used to compare the results for both physical model and those of literature. Pressures are compared at low, mid, and high flow conditions. Also water surface profile for Al-Dhuloyia Spillway was compared with those of literature and for different discharge condition. It is shown that there is reasonably good agreement between the physical and that those for literature for pressures, discharges and water surface profile.

An oil sample from the Tertiary reservoir in the well BH-22 in Bai –Hassan Oil Field, Northern Iraq has been analyzed by the means of GC and GC/MS. The identified biomarkers and the stable carbon isotopes indicated a low salinity marine carbonate depositional environment for the precursor organic matters of the oil. CPI, 20S/ (20S+20R) C29ST, ββS/ (ββS+ααR) C29ST and other maturity biomarkers showed a moderately mature oil. Non effect of biodegradation has been found out from the ratios of P1, P2, and P3 and from the absence of 25-Norhopane biomarker. A Star diagram has been drawn for the analyzed oil sample as a finger print using C9 – C20 alkanes.

Fiber loss is a fundamental limitation in realizing long haul point–to-point fiber optical communication links and optical networks. One of the advanced technologies achieved in recent years is the advent of erbium doped fiber amplifiers (EDFAs) that has enabled the optical signals in an optical fiber to be amplified directly in high bit rate systems beyond Tetra bits. In this paper, a simulation of an EDFA has been studied to characterize Gain, Noise Figure of a forward pumped EDFA operating in C band (1525-1565 nm) as functions of Er+3 fiber length, injected pump power, signal input power and Er+3 doping density. The simulation has been done by using Optisystem 5.0 software simulator (license product of a Canadian based company) at bit rate 10 Gbps.

Let R be a commutative ring with identity and M be a unitary R-module. An R-module M is called finitely annihilated if there exists a finitely generated R-submodule N of M such that ann(M)=ann(N).Our main purpose in this work is to study this property in some known classes of modules such as quasi-injective, multiplication and other modules. We prove that:
1-If M is a quasi-injective R-module, then M is finitely annihilated if and only if M is finendo.
2-If M is a multiplication R-module, then M is finitely annihilated if and only if M is finitely generated.
3-M is a faithful finitely annihilated R-module if and only if M is a compactly faithful R-module.

The simple abstract we can talk about in this project is about the idea of information security has became very important thing in our life, so we can not depend only on data or information encryption but hiding it too which is called (Steganography).So it is a method in which we hide an information inside an other so the real information or data can not be seen. The information we want to hide in this project is a text message to be hidden in a picture which is a BMP (Bit Map) format which is simple. We will use the programming language (Visual Basic) to do this job, Hiding a text message in a picture needs on the other hand getting the image back from the picture so the program will contain this operation too.The data of the BMP picture will be replaced by the hidden text message so it may cause distortion in that place therefore the message must be distributed all over the picture so the distortion would be reduced. In the future we can hide another type of data inside another type of carrier (out world data) such as hiding text inside a voice file.
