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.

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

DOI: 10.33899/edusj.2019.125843.1001

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.

DOI: 10.33899/edusj.2019.125920.1006

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.

DOI: 10.33899/edusj.2019.126025.1016

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.

Isolation and Diagnosis of Bacterial Infections Among Children in the West Bank of Mosul City


DOI: 10.33899/edusj.2019.125919.1005

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.

DOI: 10.33899/edusj.2019.126043.1017

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.

DOI: 10.33899/edusj.2020.126339.1032

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.

The fungus was identified according to the morphological characteristics and microscopic features, as well as penetration of the hair by the fungal hyphae Results on the effects of environmental conditions on the growth and sporulation of the pathogen showed that the best medium for optimum growth of the fungus occurred on Potato Dextros Agar (PDA) medium with an average diameter of colonies 88 mm followed by 85.33mm and 82.66mm and 60.00mm for Sabouraud dextrose agar (SDA), Oatmeal agar (OMA) and Trichophyton agar no.4 (TNo.4) respectively. The least growth was observed on Rice agar +tween 80 ( R-t80 ) with 44.66 mm Minimum sporulation of the fungus was detected on SDA and reached 2.84x102 conidia/ml Optimum temperature for the growth of the fungus was 28C̊ with 84.88 mm colony diameter while 62.33 mm at 15C̊. No growth was observed at 35C̊ on (PDA). Average diameter of fungal colonies was 84.66 mm at the optimum pH 5.5, Growth and sporulation of the fungus increased proportionally with incubation period reached maximum after 12 days and gave 88.00 mm and 3.18x102 conidia/m respectively . While the least incubation period was noticed at the 4th day and colony reached 29.33 mm and 1.40x103 conidia/ml sporulation . Testing the efficacy of four antifungal drugs viz - Nystatin ( Nys ), Griseofulvin (GRF), Fluconazol (FLZ) and Itraconazol (ITZ) on the growth and sporulation of T.tonsurans proved that Griseofulvin was the most effective antifungal which cause complete inhibition (100%) at 40 mg/ml followed by Fluconazol and then Itraconazole, while the least effect was detected with Nystatin which gave colony diameter 25.00 mm and 66.33 conidia/ml.
