This paper is an attempt to investigate the concept of definiteness which is of special interest because it seems to be discourse - pragmatic in nature but it has semantic impact. In English, definiteness is syntactically encoded by the definite article ''the''. The definite article can be discussed on different perspectives: syntactic, semantic, discourse- pragmatic, and cognitive. Much of the research into the meaning of the definite article'' the'' can be clustered under two main headings: theories that analyze the article in terms of unique identifiability and those that analyze ''the'' in terms of familiarity. This paper aims at showing that referential theories provide only partial accounts of the meaning and distribution of the article. In addition to its referential function, the definite article has another function, including notions such as: topic–comment, new–given information, presupposition – focus, prominence, and viewpoint. Focusing principally on the definite article, the paper investigates that literary works may be used to indicate certain entities that have not been mentioned beforehand in the texts. For this reason, evidences drawn from different literary texts have been analyzed depending on discourse-pragmatic and cognitive frameworks which are important for understanding the many subtle shades of meaning conveyed by the definite article.

Fifteen A.flavus isolates were isolated from apple fruits which appear on it symptoms of infection ,the results of our study showed 13 isolates (86%) from these isolates had ability to produce aflatoxins .The results showed that this metabolic products had substantial effects on duodenum of albino rabbit ,e.g. cause Focal Aggregate Inflammatory cells (Mast cells ) in villi of duodenum and swelling of villi cells at 100µL/Kg. Similar tendency took place at concentration 200 µL/Kg, in addition to necrosis and Vascular Congestion in mucosa layer, while at 300 µL/K dose more effect were happen than above doses e.g. Vascular Congestion in mucosa layer and complete degradation in villi . When another group of animals are treated with doses of metabolic product together with different doses of Punica juice ,the toxicity effects of metabolic products of A.flavus was reduced at all levels of doses, where the effect of juice was increased by arising doses amount ,the results showed that the (200) µL/Kg of juice prevent the swelling of villi cells, while aggregation of inflamintray cells remain in villi was not recovered with same concentration , but when the dose increased to (400 ,800) µL/Kg lead to prevent all toxic effect were caused by metabolic product in (200 and 400) µL/Kg

The aim of this study is to construct and utilize a requirement model as basis to develop e-Courses Management System (eCMS) so as to overcome all courses issues in the university in a proper and effective way. This case study which focuses on e-courses activity as the domain of study was conducted at Thi-Qar university. So hopefully that this constructed model will help system developers to understand the requirements to build the system that includes concept, flow and procedures in managing e-courses activities. The observation, interview, and requirement model analysis were used in this study as fact-finding techniques to define the requirements, Unified modeling language (UML) have been used to construct this requirement model that consists of certain model diagrammatical such as use case diagrams, class diagrams, activity diagrams and interaction diagrams (sequence diagrams and collaboration diagrams) and supported by certain textual information like use case specification and requirements list that consisted of 32 functional requirements and 12 non-functional requirements that were needed to construct requirement model for eCMS. However, in this study only functional requirements be captured. This model is validated by using test script technique and sample system (prototype). eCMS is proposed to be a web-based system that enables better communication regardless of time, and location of users. This study provided a better solution to develop eCMS that can be implement at all universities as well as the related education organizations in Iraq.

الخلاصة

يهدف البحث إلى دراسة قابلية اللحام للصلب الثنائي الطور المنخفض الكاربون المنتج بطريقة التلدين المستمر { تقسية الصلب المنخفض الكاربون ( 0.10% C ) من درجة حرارة (850 ) مْ لمدة (15) دقيقة } باختلاف معدل التبريد (المحلول الملحي، الماء، الزيت ) وزمن التلدين ( 20,15,10,5 ) دقيقة.
أوضحت نتائج البحث إن زيادة معدل التبريد يزيد من كمية المارتنزايت، وهذا بدوره يخفض من قابلية اللحام للصلب الثنائي الطور. ولكن نسبة الكربون المنخفضة جعلت من الماء كوسط تقسية مناسب لإنتاج الصلب الثنائي الطور وبقابلية لحام أفضل مما لو كان وسط التقسية المحلول الملحي.
كما أوضحت النتائج إن زيادة زمن التلدين يزيد من نمو جسيمات الأوسيتايت المتكون ولا يزيد من كميته، حيث عندما يكون زمن التلدين أكثر من (10) دقائق فأن التركيب هو عبارة عن فرايت مضلع – مارتنزايت ولكن عندما يكون الزمن (10) دقائق أو اقل فأن التركيب يكون عبارة عن فرايت مضلع – بيرلايت مع كمية قليلة من المارتنزايت. أما قابلية اللحام فهي تعتمد على كمية طور المارتنزايت وتجانس توزيعه ضمن أرضية المعدن الأساس.

Although his family was considered as middle-class, Bob Dylan's choice of writing style and topics tended to be influenced by a smaller-voiced, more suffering group- that of the working class. His lyrics that have included many protest and finger-pointing messages, have always been looked upon as influential in the shaping of cultural views of the time. Because he has used his lyrical poetry to inspire people to make changes, and to right the wrongs of the world. Most of Dylan's lyrics were dedicated to speaking out against infractions committed by the world at large. And the vast amount of his lyrics has been written with the interest of social justice in mind. His work illustrates working-class literature themes as composing the majority of the people in America in particular and the world in general referring ,also, implicitly to the other suffering classes, such as emphasizing the collective, being experimental in terms of style, being written in working voices, resisting the powers that be, and calling to action those who are reading his messages. And such is his modern realistic vision

الخلاصة

أن الاختبار القضائي أو مراقبة السلوك هو نظام عقابي قوامه معادلة تستهدف التأهيل وتفترض تقييد الحرية عن طريق فرض التزامات على الحدث والخضوع لأشراف شخص.مما يعني أن جوهر الاختبار القضائي (مراقبة السلوك)أنه نظام عقابي يجري خارج أسوار المؤسسات العقابية ومن ثم فهو لا يفترض سلب للحرية ولكنه يفترض تقييد لها.فالفرضية العقابية التي يفترضها الاختبار القضائي(مراقبة السلوك)غير مستقرة،فهي تنطوي على عنصر الاختبار أي مدى الصلاحية لها.فإذا ثبت جدواها تحقق التأهيل عن طريقها وأكتفي بها.أما أذا ثبت فشلها،فمعنى ذلك أن الخاضع لها يحتاج الى الأساليب التي تطبق في داخل المؤسسات العقابية فلا يكون مفر من أن تسلب حريته ليتحقق عن هذا الطريق تأهليه.ولذلك فأن الاختبار القضائي (مراقبة السلوك)يقوم على عنصرين هما:أولا- تقييد الحرية بما ينطوي عليه من أشراف ورقابة.
ثانيا- معنى التجربة بما يرتبط به من احتمال سلب الحرية عند فشلها.
فالاختبار القضائي (مراقبة السلوك) من التدابير العلاجية يتواجد الحدث عن طريقه في بيئته الطبيعية بين أسرته أو في أسرة بديلة إذا كانت أسرته غير صالحة،ولكنه يكون خلال فترة المراقبة تحت أشراف ورعاية ممثل لمحكمة الأحداث يعرف بضابط المراقبة أو المشرف الاجتماعي.وقد أعتمد المشرع العراقي الأخذ بالاختبار القضائي(مراقبة السلوك)في مرحلة المحاكمة والتي تتمثل في القرار الذي تصدره المحكمة يوضع الحدث تحت مراقبة السلوك كتدبير مستقل بذاته غير تابع للحكم بعقوبة معينة.ويوضع الحدث تحت الاختبار القضائي(مراقبة السلوك)في جرائم الجنح والجنايات فقط،لذا أورد المشرع قيدين على الحالات التي يجوز فيها وضع الحدث تحت الاختبار القضائي(مراقبة السلوك)هما:
أولا-الحدث الذي يرتكب مخالفة،إذ لم يجز القانون وضعه تحت المراقبة،وإنما قرر الحكم بإنذاره في الجلسة بعدم تكرار فعله غير المشروع أو تسليمه الى وليه أو أحد أقربائه ليقوم بتنفيذ ما تقرره المحكمة من توصيات لضمان حسن سلوكه وتربيته.ثانيا-استثناء جرائم الجنايات المعاقب عليها بالإعدام أو السجن المؤبد من وضع مرتكبيها تحت نظام مراقبة السلوك،إذ يقرر الحكم عليهم بدل هاتين العقوبتين الإيداع في أحدى مدارس التأهيل.

Pot experiment was conducted in a private field located on the main road of Kerbala – Babylon , 10 kms eastern of Kerbala during season 2010 -2011 . The aim of this study was to assess the effect of water stress and proline on the root growth of four wheat cultivars . The root growth parameters were root diameter , root length , root volume and fresh and dry weight of the root . Factorial experiment within completely randomized design with four replicates was applied . The experiment included four wheat cultivars ( ie. Fateh , Adnania , IPA 99 and Sham 6 ) , three concentration of proline ( ie. 0 , 20 and 40 ) mg . l-1 and three levels of field capacity ( ie. 25 , 50 and 100% ) . The results could be summarized as follow : 1- The effect of cultivars was significant on the previous mentioned traits . Fateh cultivar gave the higest root length and shoot fresh weight , ipa 99 cultivar gave the higest root dry weight , whereas Sham 6 gave the highest diameter , volume and dry weight of root . On the other hand , Fateh gave lower values of diameter , length and volume of root , Adnania gave lower fresh weight of root 2- Concerning proline treatment , proline at 20 mg . l-1 was more effective on all studied parameters compared with other concentrations ( ie. 0 and 40 ) mg . l-1 . 3- The field capacity of 100% was the best compared with 25% and 50% field capacities . 4- The interaction between cultivars and the proline was significantly effective on the studied parameters where cultivars treated with 20 mg . l-1 proline gave the highest values compared with the control treatment ( ie. 0 mg . l-1 ) . 5- The interaction between cultivars and the field capacity was also effective on the root growth parameters . cultivars grown with 100% field capacity gave higher values of the root growth parameters . on the other hand , those cultivars grown with 25% field capacity gave the lowest values of the previous mentioned parameters . 6- The interaction between the proline and field capacity was also significant on the studied parameters . the proline at 20 mg . l-1 and 100% field capacity treatment gave the highest values of studied parameters whereas plants grown with 0 mg .l-1 and 25% field capacity gave the lowest values of root growth parameters . 7- Apart from the root dry weight , the interaction between cultivars , proline and field capacity was also significantly effective . Cultivars grown with 20 mg . l-1 proline and 100% field capacity gave the highest values , on the other hand, those cultivars grown without proline application , and 25% field capacity gave the lowest values of root diameter , length , volume and the fresh weight .

The chemical Bisphenol A (BPA) was first synthesized in 1891; in 1930 a study found that BPA mimics estrogen. Today bisphenol A (BPA) is manufactured in excess of six billion pounds per year. BPA is most commonly used as the building block of polycarbonate plastic for products such as baby bottles and water bottles, epoxy resins (coatings that line food containers), and white dental sealants. It is also an additive in other types of plastic used to make children’s toys. BPA molecules are bound by "ester bonds” to form a polymer used to make polycarbonate plastic. As the building block of polycarbonate, BPA is the primary chemical in polycarbonate, and it does not exist in only trace amounts. While plastics are typically thought of as stable, scientists have known for many years that the chemical bond between BPA molecules is unstable. The bond is disrupted by heat and acidic or basic conditions that release BPA into food or beverages in contact with the plastics. Now, there have been over one hundred studies that link BPA that can cause cancer and other health conditions in exposed people. Pregnant woman who absorb a common chemical from everyday plastic products such as water bottles and other containers could be putting their unborn children at a risk of developing cancer and other diseases when they reach adulthood. Animal studies found that exposure in the womb to Bisphenol A caused changes associated with obesity, cancer and diabetes. This chemical is banned in Canada, some states in U.S, other European countries, in the last two decades, more and more breast cancer in Korea has been related to BPA. Now, breast cancer is ranked the leading cause of cancer in Korean woman.

Iraqi government is actively promoting wastewater reclamation because of urgent water needs. Wastewater reuse is governed by stringent regulations to protect public health against waterborne diseases and any other adverse environmental effects. This study is aimed at determining the type and level of advanced treatment needed for effective treatment of 60000 m3.day-1 domestic wastewater of an Iraqi city without major modification of plant layout. An urgent request by the Iraqi government to implement nutrients and phosphorous removal units for an under construction project. Extensive investigations were carried out to size and add both Phosphorus & Nitrogen (P & N) removal units into the plant layout. Due to limitation of site land, it was found itself obliged to work on redesigning the aeration basin of the WWTP. The aeration basin consists of eight cells of (25x25x5) m3volume. The redesign approach adopted here involved two main objectives; one objective is to utilize part of the aeration basin as Phosphorus & Nitrogen (P & N) removal units while the second objective is to raise the efficiency of the aeration basin to handle the original influent with the remaining cells to deliver the standard effluent specifications. A cost effective study was carried out to use Advanced Oxidation Process (AOP) based on Fenton's process to achieve both objectives mentioned above. Fenton's process using H2O2 to react with wastewater in the presence of Fe++ prior to the aeration tank resulted in considerable reduction of BOD entering the aeration tank. The study has revealed that AOP is effectively accomplishing the target, and reducing the volume of the aeration basin to less than 60% of its original volume (capacity). The cost analysis shows a cut in per unit cost from (0.17 $/m3) to (0.16 $/m3).

A numerical study has been performed for laminar natural convection in a square cavity containing a heated plate located at vertical and horizontal situations by using finite difference method. Top and bottom of the cavity are adiabatic, the two vertical walls of the cavity have constant temperature lower than the plate’s temperature. The flow is assumed to be two-dimensional.The significant parameters are Grashof number(Gr),aspect ratio(A) and position of the thin plate(A1,A2).Grashof number is varied from , while aspect ratio and positions of the heated plate were studied(A=0.25,0.5,0.75),(A1=0.25,0.5,0.75) respectively.Air was chosen as a working fluid(Pr=0.7).In present study, the effect of the position and aspect ratio of heated plate on heat transfer and fluid flow are reported.From the present analysis it is found that with the increase of Gr, the heat transfer rates(Nusselt number) increases in both vertical and horizontal positions of the plate. When aspect ratio of the thin plate decreases, also decreases.For vertical situation of the plate, heat transfer is more enhanced than for horizontal. The numerical results of average Nusselt number values have been confirmed by comparing it to similar known previous works using the same boundary conditions. Good agreement is obtaine.

Sixty specimens, thirty from cold cured acrylic and thirty from heat cured acrylic were prepared, flasking and packing procedure were done according to manufacturer direction and divided according to polymerization as follow:20 specimens(10 from cold cured and 10from heat cured acrylic)were polymerized by ivomat curing device containing water under air pressure 30 Pascal for 15 minutes at37˚C. 20 specimens (10 from cold cured and 10from heat cured acrylic) were polymerized by microwave oven; the power level was set at 50% to get 500 watts output for 3 minute and 20 specimens (10 from cold cured and 10from heat cured acrylic)were polymerized by water bath (fast cycle).All specimens were tested for tensile strength. Result showed that the cold cured acrylic have high value of tensile strength when processed by elevated temperature (by water bath and microwave) in comparison to those processed by conventional methods (Ivomate)with highly significant differences P<0.01, There was no significant differences P=0.11 between cold cured acrylic groups that polymerized by water bath and heat acrylic groups that polymerized by microwave. Heat cured acrylic that polymerized by water bath show the maximum value for tensile strength followed by heat cured acrylic that polymerized by microwave, then by cold cured acrylic groups that polymerized by water bath ,while the least group for the tensile strength recorded by heat cured acrylic that polymerized by Ivomate. Also show there was significant and highly significant differences between all groups (cold and heat cured acrylic) processed by three methods (Ivomate, water bath, microwave).

All metals are potentially toxic, but, some metals are essential for life. Heavy metals become toxic when they are not metabolized by the body and accumulate in the soft tissues. Heavy metals may enter the human body through food, water, air, or absorption through the skin when they come in contact with humans in agriculture and in manufacturing, pharmaceutical, industrial, or residential settings. Industrial exposure accounts for a common route of exposure for adults [1]. We get exposed to these metals from our surroundings whether our immediate environment or our place of work. This study focused on the workers that worked in industrial field and they are always keeping touch with minerals like Fe, Pb, Zn and Co. These minerals may be poising if they were overdose and causes many healthy problem if the concentration of these elements increased in human body more than body requirement. The occupational exposures for these elements by inhalation or touching or orally are very risk on the healthy. So the present study included twenty four tinkers, and mechanic subjects that work in tin, solder and car repaired and fifteen subjects that were non-worker as control group. The elements, lead, zinc, iron and cobalt were determined in serum of each subject. The results revealed highly significant increase (p<0.0001) in concentration of Pb, Zn, Fe and Co comparing with the control. The worker subjects were classified into groups according to age, smoking, period of working, and obesity depending on body mass index (BMI) then studies their effect on the concentration of these elements. The results showed no any significant differences between each group. There is no significant differences between subjects their age (18-40)year and those (41-60) year in addition no significant differences between smokers and non-smoker groups, obese and non-obese group and no significant differences between workers that works within the period (1-5) year and (6- 15) year. The aim of this object was investigated the association between the elements, Pb, Zn, Fe, Co as a risk factors and workers that work in industrial field and they are always touching with these element.

A simple and accurate spectrophotometric method for the determination of capoten is applied. The procedure was based on the chelate formation with nickel(II) in acidic buffer medium. The complex has a maximum absorption at 617 nm. The optimum conditions for the complex formation were ascertained and the method was developed for the determination of capoten in the concentration range of (20–60) mg/L. The empirical formula of the formed complex was determined, by applying different spectrophotometric methods, at optimum pH of (3-5) and an ionic strength of µ equal to 0.5 M. The stoichiometric ratio was found to be 2:1 of Capoten-Nickel (II) complex as calculated by continuous variations and the mole ratio methods. The continuous variations method was applied for the determination of the conditional stability constant of the formed red complex and was found to be 3.27x107. The proposed method was found to be suitable for the determination of capoten in pure form and in its commercial tablets.

An experiment was conducted in one of the plastic houses belong to the Kufa Technical Institute during the growing season of 20092010 , to study the effect of different concentrations of Zinc on the toxicity of Sodium chloride for tomato plants grown in soil that suffer from Zinc deficiency. The experiment included three conc. of Zn i.e.(Zero, 3, 12) mgZnKg. Soil and three conc. of NaCl, i.e.(Zero%,0.5% and 1.5%) ,which added to irrigation water . After 60 days from growth, plants had harvested. Dry matter, Zn, Na, K, P and K/Na ratio were determined. Results showed that there was highly decrease in the amount of Zn in the soil which reflected its effect in the decrease of growth, particularly in highly salty condition (1.5%). Increasing in NaCl resulted in a decrease in the amount of vegetative parts dry matter, this reduction was higher with soil that treated with 3 mg ZnKg soil compared with soil that treated with 12 mg Zn Kg soil. Addition of Zn from 3-12 mg ZnKg soil caused an increase in K conc. from 37.8 to 40.9 ; 25.6 to 30.6 ; 21.0 to 22.9 mgg dry matter, respectively, and a decrease in the Na conc. from 3.6 to 0.7; 8.7 to 5.4 and 28.7 to 21.9 according to the conc. of NaCl that used (i.e. Zero, 0.5 and 1.5%), respectively . Consequently , K/Na ratio of plants were highest in the highest Zn application conditions . Result of experiment also revealed that importance of Zn to improve plant tolerance to soil salty conditions and the use of suitable amount of Zn causes an absorption increase of Na by roots in salty conditions. It could be concluded that the use of suitable amount of Zn of importance for plants survival at convenient degree of growth at salty conditions.

The 14 MeV neutrons buildup factor in paraffin wax, graphite and lead have been experimentally determined using the BF3 counter up to a thickness of 2.5 mean free path ( mfp ).The dependence of the secondary neutrons spectrum transmitted from all selected materials on the thickness at the fixed incident neutron energy has also been studied using a liquid organic scintillation detector type NE 213. Results indicate that, the value of buildup factor remains close to unity up to penetration depths of 0.4 mfp and then increases when sample thickness increased. The neutron spectra obtained in this research depends on the material type and thickness. In general, the neutron spectra decrease with increasing sample thickness. Comparison of the experimental results obtained with the previously calculated neutron buildup factor shows a good agreement.

In this paper we have developed the method of Linear Interpolation which is considered the simplest way of the interpolation methods. We have been able to deduct a new interpolation formula that termed (New Formula of linear Interpolation). It has been proved, through the new formula that the results obtained are more accurate than the results obtained by using the Linear Interpolation. Moreover there is no need to reduce the value of (h) to have a good approximate value. For comparison purposes, other methods were used like: Lagrange Interpolation, Taylor Interpolation and Linear Interpolation. On the other hand, the researchers have used the Law of Error of interpolation.

This study was designed to test the antioxidant and antimutagenic activity of methanolic water extract of clove. The extract has been described by using thin layer chromatography TLC, the results which showed the presence of more than one component of this extract and when examining the activity of antioxidant by beta carotene spray process , It was observed appearance of the antioxidant activity in several bands . The antioxidant activity was determinated for these bands through the retention of the color yellow, which indicates the existence of effective antioxidant in some components of clove extract. When rats treated with 2 mg/kg of MMC lead to increased the level of DNA fragmentation and the interference treatment of extract at 500 mg/kg (with) and (after) the mutagen performed decrease the level of fragmentation,Thes results may indicate that the extract works as desmutagenic agent, while when given befor the MMC, the extract may works as antimutagenic agent. So the result of the oral gavage of mixing the extract with mutagen for five weeks reducing the level of the crash in the DNA compared with negative control. The results of MI of the interference treatment with extract (with) and (after) the mutagen performed a best result in the raising of median MI to 2.43 , 2.13 respectively compared with the positive control 1.16, while the extract before the treatment with mutagen did not posses any significant differences 1.68 compared with positive control .The result of the oral gavage of mixing the extract with mutagen for five weeks had been showed, in the first week led to raise the median MI. The result of chromosomal abnormality CA of mice stem cell possessed a high significant difference in the positive control 26.0 compared with the negative control 5.33, while in the interference between the extract and mutagen the result showed a decrease in the median of abnormality to both treatment (with) and (after), while the treatment ( before) did not posses any significant difference compared with positive control . Also the results of median chromosomal abnormality of the interference treatment (with) to five weeks showed a decrease in the median of CA. The results of this study refer to that the clove extract have antioxidant and antimutagenic activity In vivo and In vitro.

Electrical and optoelectronic properties of CdTe¬1-xSex/ZnTe Heterojunctions(x=0.1,0.2,and 0.3) have been investigated .C-V characteristics suggest that the fabricated heterojunction was abrupt type, built in potential determined by extrapolation from C2 V curve to the point (V=0). Also from C-V measurements, we deduced that the built- in potential and the depletion layer width increases with increasing the value of x,while the charge carrier concentration decreases. The current-voltage characteristics of CdTe¬1-xSex/ZnTe Heterojunction for the forward bias at dark condition shows that the ideality factor values varies with varing the value of x. Both the short circuit current and the open circuit voltage increases with increasing the value of x.The spectral responsively has peak at (840)nm wavelength
