Chassib Fanukh Abbas Al-Jubouri

journal of kerbala university, Volume 4, Issue 2, Pages 1-14

This study is one in corpus linguistics. It examines the frequency of the grammatical categories used in six prose texts .This aspect is studied through the variables of prose text type and writer's sex. The model used to analyze the corpus is adapted with modification from Ball (1993) and Burrows (1993). The study proves that the text type and the writer's sex, in addition to the text theme determine the grammatical category used. Thus, it accepts its alternative hypothesis

Structural and Linguistic Analysis of SMS Text Messages

Muayyad Omran Chiad

journal of kerbala university, Volume 4, Issue 2, Pages 15-27

The most obvious way in which the communicative behavior has changed is reflected in virtual environments with its different modes of communication.These new modes provide a rich testing ground for theories of language change.In accordance with all the other media, the Mobile technology,in particular SMS,has brought along its own language and culture.The language of the SMS is asynchronous,a single-channel,text-based,technologically mediated discourse.It reflects the unpredictable, unrestricted new communication technology and it evolves at an incredible speed.The following study hopes to provide an understanding of SMS English by analysing interactions in these texts as constituting another form of Computer-Mediated Discourse.The analysis tackles such topics as speech acts, humor ,the dichotomy of speech and writing in relation to SMS texts,and orthography.Based on more than 164 texts messages collected from the Internet and Personal correspondences,the study finds out that correspondents of SMS create new language to suit the restrictions of the media.Expressive speech acts comprise the majority among other acts because personal opinions and emotional state are conveyed in text messages intended mainly to build social relations.Humor is significant in SMS texts messages used as an attempt from correspondents to achieve relational goals.They use the established norms of writing and speaking discourse, in addition to a non-standard orthography.

Image edges detection using morphological operations

journal of kerbala university, Volume 4, Issue 2, Pages 37-49

Morphological operation consists of two types:- Basic operations and derivative. Basic operations are ,dilation ,erosion and (hit & miss) ,where as the derivative operations are :open ,close , tophat , bothat , skeleton. The process of finding the limits of the image (edge detection) means finding the boundary between the neighboring regions which differ from each other in gray levels value .There are three basic methods for finding limits of images:-
linear, non-linear and common approximating methods.
An algorithm is applied to identify the image edges of the image, there are generally three stages:-
1-filtering procedure to reduce the noise.
2-improvement operations
3-finding the strong border points which are required.
According to the method of change the intensity image there are several types of edges of images such as (line edges, step edge, ramp edge) .
Due to the absence of specific suitable method to detect all types of edges ,the present work has been implemented three methods based on the fundamental morphological operations to find the limits and the image terminals by selecting different size and extensions converted to images of grey levels ,results were compared to determine the most suitable and better methods . The present work using matlab functions (version 6.5)

Status of Selenium in seminal plasma of Male infertility and their correlation with Various Sperm Parameters.

Nawal.KH. Hussain

journal of kerbala university, Volume 4, Issue 2, Pages 50-54

Human semen contains low concentration of selenium (Se). The presence of abnormal level of this trace element may affect spermatogenesis with regard to production, maturation, motility and fertilizing capacity of the spermatozoa. The aim of this study is to evaluate the level of Se in seminal plasma in different groups of male infertility and to correlate their concentration with various semen parameters.
Subjects and Methods:
Forty primary infertile male individuals, who had regular unprotected intercourse for at least one year without conception with their partners, aged 25-40 years were involved in the present study. After seminal plasma fluid analysis they were grouped as, azoospermic,oligoasthenozoospermic, and teratozoospermic.
Twenty males selected from general population and after seminal fluid investigation they were taken as normospermic control group. Selenium concentration in separated seminal plasma of each infertile male and fertile control subject were determined by HPLC.
This study showed significant decrease of seminal plasma Se mean (±SEM) value in azoospermic and in oligoasthenozoospermic infertile males than in infertile male controls(p<0.05),and highly significant decrease in teratozoospermic patients (p<0.005) when compared with that of fertile males.
The results also showed that there was no significant correlation between Selenium concentration and sperm count, morphology and motility.
On the basis of the findings of this study, it seems that the estimation of seminal plasma levels of selenium may aid in investigation and treatment of infertile males.

Copyright Watermarking in MPEG 1 Files

Ali Retha Hasoon Al-Moseaway

journal of kerbala university, Volume 4, Issue 2, Pages 55-63

We are living in a digital world in that extensive information exchange can be performed quickly and easily in digital format over the Internet or different storing devices in a cost-effective way. Digital data, such as music, image, video, text, e-mail, and so forth, are easily copied and transferred without any degradation. Concerns over ownership protection, data protection, and other security issues have therefore arisen. Digital watermarking is a general solution that can be used to identify illegal copying and ownership, authentication, or other applications by inserting information into the digital data in an imperceptible way. In order for a watermark to be useful, it must be perceptually invisible and have robustness against detecting processing and a variety of possible attacks by those who seek to pirate the material. In this paper we embedding watermark (text, icon) in MPEG1 file by using unused space in MPEG1 files to protect file from illegal copy and the same way could be used in secret communication (Steganography). The information embedded is hidden and the effect on the appearance and function of the work is minimized or invisible. It is supposed to survive even after digital-to-analog conversion, compression, or resizing.

Hassan. H. Ali; Basim A. Abd Ali

journal of kerbala university, Volume 4, Issue 2, Pages 110-116

A field experiment was conducted between March, 2005 and December 2007 to study the effects of different levels of crude oil ( 0.0 , 0.5 , 1.0 , 2.0 , 3.0 liter/ seedling ) on the growth of ( Casuarina equisetifolia ) under Baghdad district /Iraq environmental conditions. The results showed the adverse effects of crude oil on the plant growth. Seedlings of the experiment showed various symptoms of effects after exposing to crude oil pollution ranging from leaf paleness, yellowing, browning and drying to death depending on the level of crude oil used and period of exposure. These symptoms reflected interruption in the plant growth as a result of pollution effects on physiological processes carried out by plants. The plant growth was reduced significantly in low levels (0.5 and 1.0 liter/seedling) while the result with high levels was the death of 75% and 100% of seedlings polluted with 2.0 and 3.0 liter/seedling respectively. The present study approved that ( Casuarina equisetifolia ) could tolerate a specific levels of crude oil pollution, therefore it was suggested that this tree could be served as a plant bioremediation for soil polluted by crude oil.

journal of kerbala university, Volume 4, Issue 2, Pages 164-170

Study design and objective: This is an in vitro experimental study. It was performed to show the effect of gamma radiation on human peripheral blood mononuclear cells (PBMCs) compared with that of ordinary light. Method: First of all, PBMCs were separated and incubated in specialized culture medium to form a cell pool. Tow sample groups were prepared; one containing phytohemaggluttinin (PHA) from which three subgroups; A, B and C each with 30 samples were prepared. The effect of gamma radiation on PBMCs (group A samples) was tested against that of ordinary light (group B) and a control (group C). Another set of samples was prepared similarly, but without PHA. These two groups were incubated under standardized conditions (37°C and 5% CO2). Wet film for direct cell counting 24 hourly and Gemsa staining technique examined by inverted microscope to predict the growth curve, cell count and structural changes induced by irradiation. Results: There was a significant reduction in PBMCs counts in group A, compared to group B and C samples. Furthermore, the growth curve showed prolonged lag phase and delayed and shortened log phase in group A samples. In addition, there were more PBMCs structural changes including anisocytosis, ghost cells and abnormal mitotic figures. These finding were restricted to PHA-containing samples rather than the PHA-free set. Conclusion: The effect of gamma irradiation, represented by reduction in cell count and structural abnormalities, in vitro, was shown to be specific for activated PBMCs (i.e) exhibited on the actively dividing mononuclear cells.

journal of kerbala university, Volume 4, Issue 2, Pages 181-191

This field study carried out in 2008 at the College of Agriculture, Kerbala University dealt with different aspects of behavior, activity and pollination effect of Apis mellifera L. and native bees foraging on heads of two varieties of sunflower, Helianthus annuus L., a hybrid produced in Turkey and called “ Coban ” and an open-pollinated variety called “ Sinn el-Theeb ”. The percentages of total recorded individuals of A.mellifera and all native bees were 52.34 and 47.66%, respectively. The most abundant species of native bees were Megachile sp. and Nomia sp. while Xylocopa fenestrate, X.aestuans and other unidentified species were in fewer numbers. About 72 and 28% of all A.mellifera individuals were nectar-collectors and pollen-collectors, respectively. The displacement behavior practiced by all insect species was very remarkable. About 44% of A.mellifera and 22 to 50% of native bee individuals were forced to leave flowers through physical disturbance committed by other visitors. The study also covered other aspects including seasonal and diurnal visitation patterns and duration of a single visit / insect. The pollinating insects had insignificant effect on the yield of hybrid variety for it was highly self-compatible while they had a great benefit in this regard for the open-pollinated variety which was highly self-incompatible. For instance, mean seed-setting rates of first variety reached 88.1 and 81.4% in open and bagged heads, respectively. The rates of second variety were 79.8 and only 10.1% in open and bagged heads, respectively.

Hussein Ali Ewadh; Majeed Khudair Jassim

journal of kerbala university, Volume 4, Issue 2, Pages 192-200

Excessive volumetric change may have great influence in collapse of hardened cement mortar. Autoclave expansion test provides an index of potential delayed expansion and thereby the soundness of cement mortar. This paper presents an effort to model autoclave expansion in relation with factors affecting soundness of cement mortar.
A statistical analysis is performed for a data base of 575 chemical and physical tests obtained from archive of quality control at Kerbala plant for SRC cement. These data sets are refined to 444 by excluding outliers to avoid errors in measurement, recording, and observations. Multiple linear regression by SPSS16 software is used to develop a statistical model relating autoclave expansion with some explanatory variables (MgO %, F. CaO %, C3A %, C3S %).
Stepwise regression shows that linear model explains 89.4 % of variation in autoclave expansion by percentage of free lime to 0.05 degree of significance, while excludes other proposed variables. If the degree of significance is changed to 0.1, C3A may be included in the statistical model as second explanatory variable. The low percentage of MgO makes its effect insignificant for inclusion in the developed model. Also, the analysis shows that the restricted percentage of Tricalcium Aluminate C3A in the sulphate resisting cement may serve positively in mitigating the expansion of hardened cement mortar. On the other hand, the developed relation may give indication to control a recommended percentage of free lime in the raw materials to assure allowable soundness of cement.

Rajaa R. Abbas; N. N. Rammo; Ekram A. Al-Ajaj

journal of kerbala university, Volume 4, Issue 2, Pages 201-208

The crystalline structure, band vibration and piezoelectric properties of PVDF (neat and blend) oriented in the -phase have been investigated utilizing X-ray diffraction, infrared spectroscopy and piezoelectric measurements respectively. The -phase and -phase always exist in the solvent cast films, but with fading orientation caused by the blending content of PMMA and PVAc. Miscibility in the PVDF-PVAc blend was confirmed by vibrational band shift. It was found that the piezoelectricity of PVDF blends might strongly be affected by the final crystal structure of PVDF resulted from blending process and on the nature of blending polymer. However, the magnitude of piezoelectric constant d33 was found to be decreasing with the content of blending polymer for both PVDF-PMMA and PVDF-PVAc blends.

journal of kerbala university, Volume 4, Issue 2, Pages 209-215

During April 2004, 30- carp male infected fishes and 25 water samples from fish farm ponds in Basrah city were collected. swabs were taken from: under scales , gills , air sac , intestine , spleen , liver , heart , gonads , and kidney. Both samples were tested for bacteria. The following Gram-negative bacterial species were isolated from all samples: Pseudomonas fluorescence (41isolates),Aeromonas hydrophila (28 isolates), Escherichia coli (27 isolates),Klebsiella pneumoniea (21 isolates), Pseudomonas sp.(18 isolates), and Proteus vulgaris(17 isolates). Pseudomonas fluorescence was the dominant among Gram- negative bacterial species isolated from fish samples while Escherichia coli was the dominant among Gram- negative bacterial species isolated from water samples. The Gram- positive bacterial species which isolated from all samples were: Staphylococcus aureus(31 isolates),Sterptococcus faecalis (25 isolates), S.faecium(19 isolates) , Staphylococcus epidermidis(11 isolates), and S.pyogenes(11 isolates). Numbers of Gram- negative bacterial species that isolated from all samples were greater than those of Gram-positive bacterial species. The Minimum Inhibitory concentrations (MICs) for 10 isolates of each bacterial species were determined; Gram- negative bacterial species showed more antibiotic resistance than Gram-positive bacterial species

Asseel Majid Rasheed

journal of kerbala university, Volume 4, Issue 2, Pages 234-243

Watermelon cultivation has widely been expanded in Iraq and industrial by-products like watermelon rinds play an important role in pectin manufacture. The objective of this investigation was to determine a practical follow-up to the extraction of pectin from watermelon rinds and to characterize it in a laboratory, on a small scale, aiming at establishing the optimum conditions for acid extraction. The independent variables were citric acid concentration (0.08 – 5 g/ml) and heating time (20 – 110 min). The highest yields were obtained when watermelon rinds was dried and ground to obtain a watermelon flour to be used as raw material, citric or nitric acids were used and when the citric acid concentration was (5 g/100 ml) and the time of reaction was (110 minutes). The watermelon variety in itself was not significant in pectin yield. The degree of esterification (DE = 44.37 %) of the product obtained, as well as its physical looks, show the success of pectin extraction. Results have shown that the generated model adequately explained the data variation and significantly represented the actual relationship between the independent variables and the responses, with a correlation coefficient of (0.938) and a (44.9454 %) absolute average percent error.

Nonlinear polarization density behaviour simulation in media by electromagnetic wave influence

journal of kerbala university, Volume 4, Issue 2, Pages 252-259

Bloch's equations have been solved numerically by Runge-Kutta-Fehlberg method to evaluate the medium nonlinear polarization density behaviour. The medium has been represented as a two- level system according to the quantum theory. In this representation, matrix density formula describes the two levels coupling, under rotating wave approximation (RWA). The effect of frequency detuning (Δ) on the nonlinear polarization density shows the nonlinear polarization density decreases when the interaction becomes far away from exact resonance interaction. The response of time for nonlinear medium is increase for certain values of  (relative ratio of longitudinal to transverse relaxation time).Then, the responses will be very little as it increase

At the beginning of the experiment ;Six lambs were randomly allocated to each of the four diets ; the remaining ( six lambs) were slaughtered to provide data to relate empty body weight (EBW), hot and cold carcass weight and physical dissected gain to initial body weight. Lambs in T1 group were fed diet with no probiotic . Lambs in T2 T3 and T4 groups were fed on diets supplemented with 20 , 40 and 60 g/kg DM of Iraqi probiotic respectively .Daily nutrients intake were similar across treatments. Live weight gain slaughter weigh, hot and cold carcass weights , Empty body weight and Killing –out proportions of lambs fed diets supplemented with probiotic were significantly higher (p<0.01) than those fed control diets . However, higher improvement was achieved by lambs fed diet contain 40g/kgDM probiotic (T3). Physically dissected gain ,clearly indicated that supplementation of diets with probiotic approximately doubled the weight of lean gain (p<0.01) and slightly increased the weight of fat and bone gain (p<0.05) as compared with those fed control diets . Physically dissected lean : fat ratio was significantly (p<0.01)greater for lambs fed supplemented diets with probiotic than for those fed control diet (without probiotic) .

The determination of mercury achieved by means of Cold Hg Vapor Atomic Absorption (CVAAS ) was determined in the water and sediment samples from 7 locations at Qarmat –Ali and paper factory along shatt Al-Arab river during 2006 ,also some physical and chemical parameters were obtained during this study. The results showed low Hg content of water at station (2) (0.06 μg/ml), whereas high content of Hg has been found (0.083 μg/ml) at station (1). Another hand the lower conc. of mercury in the sediment samples recorded at station (3)(0.32 μg/g) and higher conc. observed at station (5)(0.39 μg/g). The main source of Hg in the discharge of paper factory is expected from electric cells of chlorine unit. The result also shown that conc. of mercury in sediment higher than in the water samples; This is the first study carried out in this region, and could serve as a baseline in this important area.

In this paper new azo schiff bases and tetrazole derivatives of 2-Amino-1,3,4-thiadiazole-5-thiol have been prepared.2-Amino-1,3,4-thiadiazole-5-thiol [1] was prepared by the reaction of thiosemicarbazide with carbon disulfide in alcoholic sodium carbonate solution .Compound [1] was converted to the diazonium salt which was directly converted to the azo derrivative [2] via a coupling reaction with salicyldehyde.The new azo Schiff bases derivatives [3-6] were prepared by condensation of aldehyde group of the new azo aldehyde derivative [2] with some primary amines ( 3-Amino phenol, 3-Bromo aniline ,2-phenyl ethyl amine ) and with 2,4- Dinitro phenyl hydrazine respectively in absolute ethanol. The resulting imines [3-6] were converted to the corresponding tetrazole derivatives[7-10] through 1,3-dipolar cycloaddition reaction with sodium azide in tetrahydrofuran. All new synthesized derivatives were identified by their melting points,elemental analysis and FT-IR spectra. They have long been known to posses hypnotics activities and it is hoped that our compounds would do so.

Improvement of Durability of Reed in Cement Media

journal of kerbala university, Volume 4, Issue 2, Pages 125-138

It is well-known that the durability of vegetable fibres, such as reed , in concrete media is very low because of high PH value of concrete.The improvement of the durability of reed in concrete media is investagated. Many coatings( namely epoxy paint,SBR,PVD, and liquid mastic) were used as wll as many types of salts ( soduim chloride,soduim sulfates and soduim nitrite).It is concluded that epoxy paint is the best coating in this respect. Soduim chloride is the best salt. It is,also, reported that no one of these measures is sufficiently effective in improvement of the durability of reed in concrete media.It seems that using reed with gysum plaster is more practical.
