Five varieties of bread wheat (Triticum aestivum L.) Tamuz-3 Adnaniya, Abu-Greebe-3, IPA-99 and Sham-6 and their half diallel crosses were used to study general and specific combining ability for plant height, number of tillers per plant, number of spikes per plant, spike length , number of grains per spike, 100 grains weight and grain yield per plant. The result of the analysis of variance showed that the mean square of genotypes, (GCA) and (SCA) were highly significant for all studied characters. The ratio between the component variance of (GCA) and the component of variance (SCA) was less than one for all studied characters except for plant height which was more than one this indicate the importance of additive and dominance gene effects for all characters, but the dominance gene effects is more important for determining these characters. The largest and positive value for (GCA) effect was in the following parental varieties : Abu- Ghreeb-3 for plant height and number of grains per spike, IPA-99 for number of tillers and number of spikes per plant, Adnaniya for spike length and 100 grains weight and grain yield per plant. The (SCA) effects value in some hyprids was positive with desirable direction, but other hyprids showed negative with undesirable direction  for all studied characters therefor heterosis can be utilized for improve these characters. The hyprids (1x3), (1x4), (2x3),(2x4),(2x5),(4x5) revealed desirable and high significant heterosis for all studied characters. The broad sense heritability were high for all studied, however the narrowsense heritability were high for plant height and medium to remained characters. There were over dominance for all characters except partial dominance for plant height.

The study was designed to investigate estrogen effect on testis, accessory sex glands  and sex hormones in male rats from weaning age at 21 days by using aromatase inhibitor letrozole ( 1 mg ̷ kg b. w. ) orally till 90 days of age and investigate Phytoestrogens effect ( sage extract Salvia Officinalis ) (1000 mg ̷ kg b.w.) orally and flaxseed (25 gm ̷ 100 gm diet ) with diet till 90 days of age . Study groups include : Group one control. Group two treated with letrozole and caused a significant decrease in body and testis weights, sperm number (zero sperms), serum estrogen hormone and luteinizing hormone concentration, and significant increase in serum follicule stimulating hormone concentration. Group three treated with flaxseed and caused significant decrease in body and prostate weight, live sperm percentage, sperms number and significant increase in the dead sperm percentage and serum lutinizing hormone concentration. Group four treated with sage extract and caused significant decrease in the body and prostate weight, sperms number. Group five Treated with letrozole and flaxseed caused significant decrease in seminal vesicle weight, serum testosterone and follicular stimulating hormone concentration and significant increase in the sperms number, live sperm percentage. Sixth group treated with letrozole and sage extract and caused significant increase in sperms number and life sperm percentage, serum estrogen hormone concentration and significant decrease in serum testosterone hormone concentration. It was concluded that inhibition and reduction of estrogen hormone concentration in male rats by treatment with aromatase inhibitor letrozole produced negative effects by decreasing the body and testes weight, live sperm percentage, sperms count, concentration of estrogen hormone while administration of flaxseed and sage extract produced positive effects in reproductive efficiency through the increase in the percentage of live sperm, estrogen and luteinizing hormone concentrations and spermatogenesis in adult rats.
We concluded from the study the important role of estrogen hormone in reproductive function of male rats which cleared by the negative effects that resulted from lowering estrogen hormone level by using aromatase inhibitor letrozole and the administration of flaxseed and sage extract improved some effects produced by estrogen hormone deficiency.

A sensitive spectrophotometric method for the determination of nitrazepam in pure as well as in dosage form is described. The method is based on the reaction of reduced nitrazepam (RNZ) with p-bromanil in the presence of borate buffer solution of pH9 to form a pink color charge transfer(CT) complex of maximum absorption at 340 nm. Under the optimized reaction conditions, Beer’s law correlating the absorbance with nitrazepam concentration was obeyed in the range of 0.8-9.6 μg ml-1. The molar absorptivity was 1.977×104 L mol1cm1. The limits of detection was 0.093μg ml-1. The accuracy and precision of the method were satisfactory; the average recovery was 102% and values of relative standard deviations better than 1.5 %. The stoichiometry of the reaction was studied, and the reaction mechanism was postulated. The proposed CT complex formation method was successfully applied to the determination of nitrazepam in its pharmaceutical tablet with good accuracy and precision. The results obtained by the proposed method are compared with those obtained by the official method.

Natural language means a language that is used for communication by human. Natural Language Processing (NLP) helps machines to understand the natural language. The natural language for the web pages consists of many semantic relations between entities. Discovering significant types of relations from the web is challenging because of its open nature.
In this paper we survey several important types of semantic relations. This paper also covers the relation extraction (RE) approaches which are divided into: supervised approach, which contains Feature base and Kernel base, and the unsupervised approach. Three relation extraction algorithms are discussed: Support Vector Machine (SVM), Genetic algorithm and Naive Bayes classifier
This survey would be useful for three kinds of readers First the Newcomers in the field who want to quickly learn about relation extraction. Second the researchers who want to know how the various relation extraction techniques developed over time. Third the trainers who just need to know which RE technique works best in different settings

A simple, sensitive and selective spectrofluorometric method has been developed for the determination of enoxaparin sodium in bulk and dosage forms (injection). The method was based on the quantitative quenching effect of enoxaparin on the native fluorescence of acriflavine due to the formation of nonfluorescent supramolecular ion issociation complex between the studied drug and acriflavine dye in aqueous solution. The decrease of acriflavine fluorescence was observed at 506 nm after excitation at 402 nm. The relationship between quenching fluorescence intensity and concentration of enoxaparin sodium was linear in the range 0.05-20 µg/ml and with correlation coefficient 0.9990 and with LOD and LOQ 0.011 and 0.035 µg/ml respectively. The average recovery was 100.51% and RSD is less than 3.23%. The stoichiometry of enoxaparin to acriflavine was calculated a 1:4. The method was applied successfully to the determination of enoxaparin form injection samples and the results were in a good agreement with certified value and standard addition procedure.

A commercial activated carbon was used for the study of adsorption of two di- azo dyes from aqueous solution employing batch method. These dyes were synthesized in our laboratory from the reaction of 4-amino-antipyrene 4-AAP and β-Naphthol with p-amino phenol and p-amino benzaldehyde via diazonium ions. The effect of pH, temperature, and contact time on dye removal was investigated. The apparent thermodynamic parameters were estimated and the obtained results concluded that, the dyes adsorbed onto activated carbon are driven by entropy effect, exothermic and spontaneous processes. The kinetic study of adsorption of the considered dyes was conducted by applying four models the pseudo-first order, pseudo-second order ,Elovich and intra particules diffusion kinetic models. The results showed that, the second order equation fit better the experimental data. The intra particule diffusion model indicates that, there are more than mechanism
controlling the adsorption process.the adsorption process occurs through more than one mechanical and that the intra particule diffusion model is not the only mechanical that controls the adsorption of systems Studied.

This work studies the gradient energy coefficient ( ) which has the main function in extracting the properties of the polymer, starting from the Simha-Somcynsky theory (SS) that describes the thermodynamic properties of both low and high molecular weights in terms of occupied site fraction (y). Cahn-Hilliard (CH) theory which clarifies the free energy profile of polymer surfaces or interfaces has been also adopted in this study. To gain accurate results, these two theories have been combined with that of Freed Bawendi, which gives the architecture structure for the polymers. Ultimately, the conjunction of these theories produces important properties of polymers such as; the molecular weight, surface tension, the gradient energy coefficient. This study has been performed in the temperature range (313 -473) K and up to about (150) Mpa of pressure according to the international condition of LaGrange for polymers. The success of our study can be clearly seen in the minimum and maximum deviations in (0.036) and (0.128) respectively, while the exact value of gradient energy coefficient has been proved in the high molecular weight polymers as in (PEG 18500). The gradient energy coefficient and the reduced surface tension are directly proportional to molecular weight, while the gradient energy coefficient is inversely proportional to both hole fraction and temperature. The study has been accurately proved by the obtained results and data given in the graphs.

Bacterial infections are common in neonates, infants and children.. Some of these infections are serious and usually carry high risk of fatal complications such as septicemia / meningitis if left un-treated. Diagnosis of such infections is usually clinical together with the identification of bacteria in body fluids such as urine, stool, blood and CSF. The aim of the current study is to isolate and identify bacteria responsible for some types of serious bacterial infection in neonates such as UTI, GIT infections and bacteremia in West bank of Mosul city sand test their susceptibility to different antibiotics. Our results indicated that Staphylococcus aureus was the most common bacterial isolate in blood (81%), whereas both Staphylococcus aureus and E. coli were common in urine (48% and 43% respectively). These microorganisms are highly sensitive to amoxiclav (83% for Staph , and 100% for E.coli) , levofloxavin ( 88% for Staph. and 100 % for E.coli) and meropenem (100% for both Staph and E.coli). However, both of them highly resistant to ampicillins (100% resistant rate) and 3rd generation cephalosporins. Although meropenem is effective, its use should be selected and restricted to highly resistant cases to avoid the emergence of early antibiotic resistance.

Comparative study of the physical characteristics of n-ZnO/p-Si heterojunction diode has been done as a function of deposition temperature in the range of 300-600 °C. Transparent conducting (TC) Zinc Oxide (ZnO) thin films were deposited by atmospheric pressure chemical vapor deposition (APCVD) technique on the p-Si(100) and glass substrates. Also, the influences of different deposition temperature on the morphology and optical properties of ZnO films were studied. Both the average surface roughness (from 62.8 to 18.8 nm) and the root mean square (from 78.2 to 24 nm) of ZnO films were decreased with the increase in the deposition temperature. Optical transmittance measurement results exhibited good transparency within the visible wavelength range for the films prepared at a temperature above 400 C. The current-voltage (I-V) characteristics of the heterojunction diodes exhibited rectification behavior and depend on the deposition temperature. The electrical parameters of the n-ZnO/p-Si heterojunctions were also affected by the deposition temperature. The diodes prepared at a temperature above 400 C were possessed lower reverse saturation current and high rectification ratio compared to those fabricated at a relatively lower temperature such as 300 C or 400 °C. Such low a temperature grown n-ZnO/p-Si heterojunction diodes with lower reverse saturation current could be suitable for photo-detection applications.

A high voltage pulse generator was development and implemented. It generates a sequence spike pulses with a varying pulse height from 0 to 5 kV; and changes the pulse width in ms range. This generator tested and used to study the pulse glow discharge in argon by using the capillary tube under pressure 0.3 to 0.5 torr. This study was to establish the nature of discharge relaxation (plasma relaxation) when a high voltage pulse causes a breakdown in the gas (coverts to conducting case). It is of great importance to answer the following question. The current can decay when the voltage pulse is switched off was obtained. The electronic switching is a successful tool which can be used for generating high voltage pulses with flexibility adjustable peak height voltage pulse, pulse duration and pulse width is presented Interesting results concerning because plasma is a function of time, linearity of time decay vs. plasma. This linearity is to seem independent on gas pressure or pulse width. The slope the current decay line is very much dependent upon the initial high voltage pulse. The condition for transition from pulse to continue like DC glow discharge condition is satisfied.

Abstract
This study was carried out inside a wired house and included the planting two cultivars of wheat (Sham 6 – IPA 99) in soils containing residues of corn (Zea may) and sunflower (Helianthns annuus) with exposing plants to three levels of field capacity (35, 60, 85%) and spraying plants with three concentrations of ascorbic acid (0, 100, 200) ppm in order to know the effect of these factors on some physiological, biochemical and allelopathic potential of wheat. The experiment has been designed on the basis that it is factorial and over completely Randomized Design (C.R.D) Duncan's multiple range test at 5% level was used to compare between the means and the results showed.
The addition of corn residues and sunflower showed a great effect in lowering plant height, relative water content, chlorophyll, number of grains / spike and grains yield with the increasing the concentration of catalase.
Exposure of plants to drought (35% field capacity) showed a negative effect on all traits above comparing to field capacity (60, 85%) except for the increase in antioxidant enzymes (Peroxidase, Catalase).
Plants submitted under two types of stress (drought + allelopathy) can improve their growth and reduce the negative effect of drought and the inhibitory effect of residues by treating it with ascorbic acid especially in the concentration 200 ppm.
More over, sham 6 was significantly superior on IPA 99 in most physiological and biochemical characters, which was reflected in the increasing grains yield.

Uropathogenic Klebsiella pneumoniae is considered the most important causes of urinary tract infection, and recently the antibiotic resistance of this pathogen has increased dramatically. The study aims at investigating the prevalence and antibiotic sensitivity of uropathogenic K. pneumoniae among different ages of groups at both genders. 1737 urine specimens were collected from individuals admitted to Zakho emergency hospital from January 2016 until December 2018. K. pneumoniae was identified based on Gram stain, colony characteristics and biochemical tests, and then it was tested for their antibiotic sensitivity. Out of all samples, 1076 (61.9%) showed significant bacterial yield. The UTIs among females (64.3%) were statistically higher than males (46.5%) (P<0.001). The age group of 20-29 years was highly susceptible to UTIs (43%). Among the total UTIs, K. pneumoniae represented 16.2%. K. pneumoniae in males (23.4%)was significantly higher than females (15.4%) (P=0.03).The age group 40-49 years (32.2%) was the highest group that at risk for K. pneumoniae infection. K. pneumoniae was highly susceptible to imipenem (100%) and was highly resistant against cephalothin (90.8%). A high prevalence of UTIs were observed among the age group of 20-29 years and the females had more risk of having UTIs. The males were more susceptible to K. pneumoniae with higher prevalence in the age group of 40-49 years. K. pneumoniae showed high sensitivity toward imipenem and high resistance to cephalothin. More awareness is required in all healthcare sectors for regular surveillance of the use of antimicrobial agents to reduce the resistance rates and to eradicate the pathogens.

In last many years ago there was a great interest in studying the existence of positive solutions for fractional differential equations. Many authors have considered the existence of positive solutions of non-linear differential equations of non-integer order with integral boundary value conditions using fixed point theorems.
G.wang etal(2012)in vest gated the following fractional differential equation
〖^c〗D^α W(t)+f(t,W(t))=0,0<t W(0)=W^" (0)=0 ,W (1)=λ∫_0^1▒〖W(s)ds 〗 were 2<α≤3

There is a growing need to produce asphalt materials with high economic feasibility, that is the production of asphalt materials with rheological properties that differ from the base asphalt (unmodified asphalt), can be used in many fields such as the production of paving asphalt, where it is not appropriate to use ordinary asphalt.
This study included the modification of the rheological properties of Daura asphalt by catalytic chemical treatment with thermoplastic polyurethane (Used in the interior parts of cars) using a microwave oven at a power of (360) watts and at different periods of time. As well as treate asphalt samples with the thermoplastic polyurethane in the presence of sulfur.
The modified asphalt samples were studied in terms of ductility, penetration, softening point and penetration Index.

A sample with good rheological specification was selected (As7) that are conform with the specifications of Iraqi Roads and Bridges Authority, The selected sample were studied in terms of conducting Marshall tests and comparing them with the original sample in order to demonstrate the possibility of using the modified sample as an paving asphalt. The obtained results showed good specifications in terms of crawl and stability values.
An aging test was also conducted on the sample (As7) of the good rheological specifications.

This study has included a modulation of the rheological properties of asphalt by a catalyst chemical treatment with polycarbonate, and the microwave technique was used at a power of (360) watt at time intervals. Furthermore, the modulation and treatment were done in the presence of sulfur and polycarbonate. The formed rheological properties of the new asphalt samples were studied which include (permeability, softening point, ductility and penetration index). Those asphalt samples of the new rheological properties could be used in paving field and some other samples could be used as anti-moisture materials.
The best asphalt samples with new rheological properties and those conformable with the properties of roads authority and Iraqi bridges were tested as a tiled asphalt since they were studied in terms of conducting Marshall tests and comparing them with the original sample in order to show the possibility of using the modified samples in the tiling and the obtained results were excellent in terms of stable creeping values. In addition the aging test was applied on the samples that contain good rheological properties.
Moreover, the modified asphalt has shown higher dissociation values in comparison with the original asphalt, so the modified asphalt has more resistant to high temperature and acid rains and shows an important characteristic of the quality of the asphalt that enables the modified asphalt to stick more closely to the aggregate, which gives higher resistance and greater operating age life to the streets.

In this study, we modify the rheolgical prioperties of asphaltic materials by addative and air blowing. For this process, asphaltic materials have been oxidized by air blowing in the presence of anhydrous aluminum chloride as a catalyst for this process . Air blowing was conducted in different condtions of temperature and times using 0.5%(by weight) from catalyst, after determining the optimal conditions for air blowing, we changged the percentage of catalyst to get the optimal perecentage which can be using in modified process, then the asphalt was treated with the commercial adhesive (EVA) in two phaths:
The first path was included addtion of different percentages from commercial adhesive under the optimal condition from air blowing and perecentage of alaminum chloride.
The second path was included dissolved the commercial adhesive in the toluene and then the modified process was conducted at same conditions in the first path, ( toluene was added to the commercial adhesive by ratio (1:6) (weight of commercial adhesive: ml of toluene).
The results showe rheological properties that are compeletly differentj from the original asphaltic materials . The study was gave modified asphaltic materials that can be using in different fields, some samples can be using in paving as in samples
(AS19, AS24, AS25) and other as mastic or as flattening as in samples (AS15, AS16, AS17, AS21, AS22). The usage of asphalitic materials in various fields depends on the measurments of different properties such as (ductility, penetration, softining point ,asphaltens percentage, penetration index ,aging test, marshall test).

A simple, precise and sensitive indirect spectrophotometric method is described for the assay of Paracetamol in its pure form and pharmaceutical formulations in the aqueous medium. The method is based on the oxidation of the Paracetamol with an excess of N-Bromosuccinimide (NBS) in alkaline medium and the residual oxidizing agent bleaches the purple-colored Eriochrom black-T (EBT) to colorless species which is measured at 516 nm at room temperature. Calibration graph is linear over 0.5-9 µg mL-1 and molar absorptivity is 3.7×104 L.mol-1.cm-1. The detection and quantification limits were 0.068 and 0.229 µgmL-1 respectively. The accuracy (Average recovery %) is 98.57, and Precision (RSD) is ≤ 1.5. No interference effect has been observed from the excipients that exist in drug formulations. The method has been applied successfully in the determination of the Paracetamol in its commercial formulations (injection, syrup, and tablet), and compared favorably with other spectrophotometric methods used different reagents. The reaction mechanism for the oxidation of Paracetamol and EBT was postulated.

ABSTRACT
The present study was investigated the immunological effects of the lipopolysaccharide extracted from Klebsiella pneumoniae against experimental infection with toxoplasmosis in mice.
Immunological changes in treated mice were compared with the +ve (mice infected with T.gondii but not treated with LPS) and -ve (mice not infected with T.gondii and not treated with LPS) group at 3,14 and 30 days post infection with tissue cysts of T.gondii in the peritoneal cavity. Total and differential WBC count of peripheral blood and innate immune response represented by the phagocytic index were the criteria taken into consideration.
Results showed a significant increase in the total WBC count in mice treated with LPS after infection with T.gondii, compared with –ve and +ve control groups. For differential WBC count, an increase in lymphocytes and decrease in monocytes, neutrophils and eosinophils was noticed. Basophils were not considered because of their low number.For phagocytic index, an increase was noticed in treated mice compared with –ve and +ve control groups, and the highest rate was observed in cncentration 500 µg / 20 gm body weight at 30 days post infection.
It is concluded that, LPS extracted from K.pneumoniae may well be used as a active and non toxic immunomodulator against infection with toxoplasmosis in mice.
