The main function of language is as communication medium . Language allows people to say things to each other and to express their communicative needs .In the interaction setting , people make use of language variation .This interaction causes them to use certain utterances which are used for specific goals or purposes . A condolence utterance is one of these utterances. Condolences are one of the communicative speech acts. They are expressions which are designed to convey one's sympathy on the occasion of someone's death . Losing someone close is a very painful experience. One can never really underestimate the power that words hold. In times of grief, especially, they provide utmost comfort. It is always comforting for the bereaved to hear kind words from his relatives or friends. So , condolences are very important. The present study is an attempt to make a linguistic presentation to the concept of condolences in English . This study aims at describing condolences from a semantic and a pragmatic point of view. Moreover, this study is intended to show the grammatical structures of condolences. The first part of this study is devoted to the theoretical framework of condolences. It involves six sections . Section one deals with the concept of condolences. Section two shows the categories of condolences. Section three tackles the description of condolences from a semantic point of view while section four tackles it from a pragmatic point of view . Section five explains how condolences can be explicit whereas section six shows how they can be implicit. The second part of the study provides the practical analysis of condolences in certain messages sent to offer condolences about the death of different people. Finally, the conclusion sums up the results of the study.

A present study was carried out to investigate the effects of Estradiol benzoate on aggressive behavior in male calves through studying the testosterone and estrogen hormones. Twenty calves were randomly divided into two groups (ten in each group) and treated as follows: calves in the first group considered as control without treated, whereas the calves in the 2nd group were injected Estradiol benzoate (0.03 mg/Kg) subcutaneously on the first day of experiment and termed as estradiol treated group, blood samples were collected on day 14 and day 28 of the experiment for measuring the hormones. Results revealed a significant increase (P≤0.05) in testosterone hormone of estradiol treated group as compared with the control group at day 14, whereas testosterone significantly decreased (P≤0.05) in of estradiol treated group when compared with the control at day 28. Furthermore, within group there was a significant (P≤0.05) decrease in testosterone at day 28 as compared with day 14. Moreover, estrogen hormone significantly increased (P≤0.05) in the estradiol treated group at all periods of experiment when compared with the control group. On conclusion it seems likely that subcutaneous injection of calves with (0.03mg/Kg) of Estradiol benzoate caused obvious decrease of testosterone and consequently inhibition of aggression in calves.

Video Steganography deals with hiding secret data or information within a video. In this paper, a modified or dynamic based least significant bit (LSB) technique has been proposed to hide movie in movie. A dynamic LSB is a spatial domain technique where the secret information such as images, or video is embedded in the LSB of the cover movie (i.e frames) by selecting number of bits to be embedded. The idea of the proposed method is take away the least significant pixels from one image (frame) which is in cover movie and uses them to store most significant pixels of second image (frame) which is in hidden movie. The hidden image’s (frame’s) values are stored in the result frame’s least significant bits so they don’t add greatly to the resulting combined video(movie). The proposed method is analyzed in terms of both Peak Signal to Noise Ratio (PSNR) compared to the original cover video with stegano video as well as the Mean Square Error (MSE) measured between the original and steganographic files averaged over all video frames.

الخلاصة

The present work presents finite element model which formulated to analyze the two- dimensional steady state seepage of water through the foundation of dam structure in the presence of inclined cutoff as seepage control device. A computer program using FORTRAN 90 language developed to determine the pressure head at nodal points, the exit gradients and the seepage discharge behind inclined cutoff walls. The results were presented by performing a parametric study for various design parameter. In this work the inclination angle()of cutoff changed (from =30 to =150), with inclined cutoff located upstream , mid distance, and downstream parts along the floor length of the dam structure respectively. The applicability of the model were examined with relevant existing approximations from literature, results demonstrate that installing cutoff in upstream part of dam structure with =60consistent with analytical solution(AE=5.11 %), while installing cutoff in mid distance of dam length agree well (AE=2.03%, for =105), the case of cutoff installed in the downstream part of dam structure strongly convenient(AE=0.2% for =30). The average value for coefficient of determination R2 for above the range of inclination angles which corresponding the various positions of cutoff wall was (0.9918,0.9713 and 0.9949) respectively, which indicates good agreement with previous studies and many of the factors studied.

The research dealt with the dimensions of place and time in Al-Jawahery's poem "O Umm Auf" .The researchers found that the poem was full of bold social criticism. The Poet began his poetic visions combination through the entrance of the time frame (gateway nights) because these nights of the poet contained treachery, intrigue and conspiracy. the poet succeeded in managing between the two times , the first is assumed and the second visualized. The Poet escaped from the pressures of everyday life. This concept of time and place aroused the poet's sadness and this appeared from the sighing which was repeated in the poems.

Ovaries were collected (120ovary) from 60 adult females camels (5-10 yr. old) slaughtered at slaughterhouse of province of Karbala in breeding season (winter). The ovaries were transported to the laboratory within 2 hours post slaughter. The follicular fluid was aspirated from small follicles (4-9mm) and large follicle (10-20mm). The follicular fluid was stored at -4 Cº prior to assay. Follicular fluid samples were analyzed for metabolites composition (glucose, total protein and cholesterol), and ionic composition (sodium, calcium and potassium). The results showed that the mean glucose and cholesterol concentration were increased significantly (P<0.05) with increased of follicular size, while the mean total protein concentration decreased significantly with inlargement of follicular size. Likewise, the mean sodium and calcium ions concentration increased significantly with changes of follicular size, while the mean potassium ion concentration decreased significantly with increased of follicular size.

The researcher chose an experimental design of partial control and randomly took Buratha Secondary School as a research sample which consisted of 60 students : 30 students represented the control group and the same number as the experimental one. The researcher equalized the two groups in some variables such as age , history marks of the previous grade: 2012-2013 , intelligence level , parent's education and critical prethinking . It was decided that the study materials represented the first three chapters of Modern and Contemporary European History . This book was chosen by the ministry of education in 2012 – 2013 . The researcher specified 124 behavioural aims for the three chapters, and prepared a lesson plan for the two groups, some of which were shown to experts specialized in Teaching Methods and Assessment and Evaluation, Psychology and History. The researcher prepared the critical thinking test of 45 items .She made sure of its validity by showing it to experts and jury , and of its reliability by applying it on a pilot sample of Jumana Secondary school through the use of Pearson's correlation coefficient .The correlation value was 79.0 after correcting it through the Spearman–Brown formula . The researcher taught the two samples by herself during the experiment period which continued for ten days . After completing the experiment , the researcher applied the critical thinking test on the two samples . The study arrived to the following finding ; there is a significant difference at 0.05 for the experimental group which studied SQ3R strategy at the expense of the control group which studied according to the traditional method of developing the critical thinking . On the light of the finding , the researcher arrived to some conclusions . Applying the SQ3R strategy in teaching History had a positive impact in increasing the students' abilities of critical thinking .It also enhances their motivations ,and concentration to the material because it is one of the modern strategies . The researcher recommends the use of SQ3R strategy in teaching followed by asking questions relevant to the lesson presented which by turn develops the students' high thinking level and deepens their understanding of the subject and critical thinking abilities . The researcher suggests to conduct a similar study on other subjects and different grades .In addition , another experimental study can be done to investigate the influence of this strategy on another variable such as the creative thinking on History subject .

A simple and highly sensitive method for the determination of ciprofloxacin in pure and pharmaceutical preparation were developed by coupling the continuous flow injection analysis via turbidimetric (T180o) and scattered light effect at two opposite position (2N90o). Where it is based upon the formation of a yellowish –white precipitate for ion pair compound by using potassium hexacyanoferrate(III) in aqueous medium. The precipitate is measured via the attenuation of incident light and it’s scattering in two opposite directions. Chemical and physical parameters were studied. The linearity of ciprofloxacin is ranged from 1 to 20 mmol.L-1, with correlation coefficient r=0.9927, limit of detection (LOD) 0.55 mmol.L-1(3SB)(S/N=3) for n=15 and the relative standard deviation for 4 mmol.L-1 ciprofloxacin solution is lower than 2% (n=6). Three pharmaceutical drugs were used as an application for the determination of ciprofloxacin. A comparisons were made between the newly developed method of analysis with the official method ( uv-vis-spectrophotometry ) of analysis using the standard addition method. It shows that there was no significant difference via the use of t- test at α=0.05(95% confidence) between the two methods. Therefore the newly developed method can be used of as an alternative method for the analysis of ciprofloxacin.

Public switched telephone networks (PSTN) has been used for decades to provide the telephony service but more and more subscribers are migrating to the modern mobile networks and the Internet. Subscribers are abounding PSTN, use it as a secondary communication option or a media to access the internet, though, legacy PSTN are expected to continue for many years before the complete extinction or total transformation to a pure broadband internet. PSTN operators are under continues pressure to provide new services and billing options rapidly and at low development costs and a possible solution is introduced here. This paper introduces Asterisk, the voice over internet protocol (VoIP) server, and the Personal Home Page(PHP) programing language as a billing service platform to be used in PSTN or any telephony system that can provide the database level access to PHP. The proposed design defines a way to interact with the PSTN database directly using the Asterisk VoIP server as call processor triggers a PHP program to perform the required calculations or transactions for every call. A system design and call flow diagrams has been presented thenimplemented using Asterisk , MySQL Database management system and PHP among other open source tools. Multiple performance tests have been carried out to highlight the performance bottlenecks and the applicability of the system as well.

X-ray rooms should be designed to provide flexibleand efficient working areas for different typesof imaging procedure. The adequacy of shielding depends on the material and thickness used for this purpose.This work therefore studies the secondary shieldingfor the control booth of the fluoroscopy room. By considering the fluoroscopy room design and the radiographic devices profiles used , the clinical total workload per week and total workload per patient have been computed and its distribution according to the most widely used voltages has been determined by recording the actual clinical technical values of maximum ,average and minimum mAs and the corresponding values of kilovolt peak for 113patients over threemonths. As a diagnostic x-ray radiation shielding reference, the National Council on Radiation Protectionand Measurements report No.147 (NCRP report No.147) and XRAYBARR computer program have been used to compute the secondarybarrier thicknesses of the control boothof the fluoroscopy room forlead and glass. It is found that the total workload per week of NCRP report No.147 is about 4.5 times that of calculated for average state and about 7 times that of calculated workload for busy state. The shielding status of control both was quite sufficient ,and about 1 mm of lead was used to shield the front wall and lead glass was used in the shielding of observation window.

Average annual wind speed in Iraq, about 2.9 m / sec, occurs highest rate of wind speed in half the warm of the year, especially in the months: May, June, and July, so recorded the highest frequency of dust storms and risingdust and suspended dust. While going less than the speed of the wind in the cold season of the year, especially in the months: November, December, and January, so recorded the lowest frequency of dust storms and rising dust and suspended dust. The station was Nasiriyah more country stations in the frequency of dust storms and dust rising, because it was the highest stations in the rate of speed of the wind. While the stations north of Kirkuk and Mosul from stations in the rate of less frequent dust storms and risingdust, because it was the less Iraq stations in average wind speed. As for the suspended dust was the highest stations repeatedly Baghdad station is the appropriate rate of winds Therefore, while it was less Rutba station terminals to the rocky nature of the soil. When extracting simple correlation coefficient application of the law Pearson appeared to be stronger relationship between the rate of wind speed and frequency of dust storms was in the station Nasiriyah about 0.971, while the strongest correlation with the risingdust in station Amara around 0.992, with the suspended dust in the station Basra, about 0.938

Zinc oxide (ZnO) thin film on crystalline silicon (c-Si) substrate has been deposited by RF sputtering method to use it for fabricating a solar cell. Structural properties of ZnO films studied using high resolution X-ray diffraction (HRXRD) analysis of the films which show that the films have polycrystalline nature with orientation (002). Small crystallite size of prepared films was calculated using Scherrir formula that indicates our films are within Nano scale. In addition, optical properties have been done via scanning electron microscopy (SEM) which used to describe the surface morphology and Photoluminescence (PL) measurements which revealed that the energy bandgap of prepared films were in the UV emission at 380 nm. Finally, thickness of the films was measured with Filmetric (F-20). Our findings were the fabricated ZnO films are successful in simple and low cost method with high quality and unexpected nanostructure behavior. Good current-voltage behavior with high conversion efficiency of 14.5 % has been obtained.

The objective of the current study was to investigate the release of Ag and Hg ions from filing. Four commercial fillings were used in the experiments, all fillings samples, disc with diameters of 10 mm and thickness 3mm were used, made by the manufacturer.Four samples of carbonated beverages (Pepsi, Seven – up, Merinda, and Sinalco) were used for each tested filling and tasted with times. The ion release from above tasted filling in the above mentioned carbonated beverages was measured over 4 time intervals, i.e. after 0, 1 , 24 hours and 7 days respectively. Carbonated beverages were analyzed by atomic absorption spectrophotometer. Results show that Ag and Hg filling released great amounts of Ag and Hg ions in all four carbonated beverages so that on the very first time of measurement these amounts exceeded the approved daily dietary intake of this elements. Gradually, the amount of the released Ag and Hg ions increased with great variability in all carbonated beverages.

Bisphenol-A (BPA), is a chemical used for the production of industrial epoxies, polycarbonate plastics, fungicides, flame-retardants, antioxidants, and other products. First synthesized in 1891, in the last few years, concerns about this chemical leaching into our food supply through canned goods and plastic containers have increased as scientists have begun linking BPA to serious health risks. BPA is used to produce almost all of our disposable drinking bottles from water to soft drinks and juice. They are labeled ‘do not reuse’ as once you open the lid and consume the contents, they begin to break down. If you rinse these bottles out and refill them, BPA will leach into the contents gradually and over time, as the plastic deteriorates, more BPA will leach into the contents. If you leave a polycarbonate bottle in the car to warm, the levels of BPA that leach into the contents are even higher. BPA is associated with a number of health problems and diseases that are on the rise in the U.S. population, including breast and prostate cancer and infertility. BPA is a potent hormone disruptor. It can impair the reproductive organs and have adverse effects on breast tissue and prostate development. It is clear that BPA exposure can pose health risks to babies first which they are more vulnerable, and to humans in general, but the important question is, should we be worried enough to change our consumption habits?

In this study, the adsorption of reactive black 5 dye was carried out by using various surfaces, namely ZnO and CaO. The validity of the adsorption was evaluated by using UV Spectrophotometry through the determination the amount of adsorbed dye. Various parameters such as pH, adsorbent weight, initial dye concentration and contact time were studied in terms of their effect on the reaction progress. Furthermore, Lagergren’s equation was used to determine adsorption kinetics. It is observed that high removal of dye was obtained at pH=5. Removal of dye was increased by increasing initial dye concentration and contact time. High removal of dye was at the time equivalent of 70 min and reached equilibrium. Increasing of adsorbent weight leads to decrease dye adsorption where 0.1gm was the best weight. For kinetics the reaction onto CaO followed pseudo-first order Lagergren’s equation while the reaction onto ZnO followed pseudo-second order Lagergren’s equation and the adsorbed amount onto CaO surface was more than that of ZnO surface.
