Abstract: This research aimed to prepare different types of asphaltic materials having a good rheological properties compared with the non-modified asphaltic materials. Different polymers and microwaves were used to prepare the modified asphalt in different ways. The first method is based on the modification of asphalt with reclaim tire rubber using anhydrous aluminum chloride catalyst at 360 watt at different times, The second method depends on the same principle of the first method with the introduction of sulfur as an additive and the third method is based on the same principle of the first method but the change of polymer added to the polyamethyl methacrylate and with the introduction of sulfur as an additive. The latter method is the same principle of the first method but the change of polymer added to mixtures of (1:1)(polymer_polymer)(recycled tire rubber polyamethyl methacrylate)with the introduction of sulfur as an additive. The above methods we obtained asphaltic materials which can be used in paving and mastic depending on the measured (ductility, penetration , softening point).

Abstract: 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.

Abstract: 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.

Abstract: The relational database model is the main focus of the database for the previous time. It provides robust data storage and structure that supports transaction characteristics and data retrieval with structured query language- SQL. The emergence  of web technologies and clustering technology in large servers called for the need to store unstructured data and move away from the pattern of tables and static fields and not topic to transaction conditions, especially in distributed systems. Instead, it used CAP theory. New data models are emergence including: Document Data model, Key-Value model, Column-Family model, and Graph model, And new programming languages that deal with these models.             An asset inventory system is a model of systems that are not topic to a fixed structure. Each location in the organization has fairly different assets and assets in the same location have different specifications that are difficult to organize in the form of tables and columns. For this reason using of  NOSQL CouchDB database system was adopted and the use of MAP-REDUCE  technology to organize data display and Cloudant Query in Mango-view method to retrieve data from the inventory database.

Abstract: 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.

Abstract: The current study was designed to detect estrogen role in adult  male rats by giving aromatase inhibitor ( ltrozole 1 mg̷  Kg. B. W) for 60 days orally to inhibit aromatase enzyme activity and to study the effect of giving source of estrogen flax seeds (25 g ̷ 100 g diet) and aqueous extract sage (1000mg ̷  Kg. B.W.) orally. The study showed that adult male rats treated with ltrozole resulted in a significant decrease in the weight of testes, prostate , percentage of live sperms , number of sperms , number of mounting , intromission, ejaculation and in the time period from mixing with females to the first mounting ,  intromission and ejaculation , the time period between mount and another, intromission and another, ejaculation and another, and significant increase  in the percentages of  dead as well as abnormal  sperms. Flax seeds treatment significantly reduced percentage of live sperms, number of sperms, number of  mounting , intromission, and ejaculation, and significantly increased percentage of dead sperms compared with control group. Sage extract treatment caused a significant decrease in number of sperms, number of mounting, intromission and ejaculation , as well as a significant increase in the time period from mixing of female to the first mounting,  first intromission and first ejaculation compared with control. The results showed that administration of sage extract with letrozole showed a significant increase in testis weight, percentages of live sperms and number of sperms, and asignificant decrease in dead and abnormal sperms compared with the letrozole group. Administration of flax seed with letrozole did not significantly change weight of the testis , prostate, percentage of live, dead , abnormal sperm and number of sperm compared with letrozole group. Administration of Flax seed and sage extracts to male rats treated with letrozole did not significantly change all the done tests of sex behavior. The study concluded that estrogen has an important role in the function of male reproductive system, which is shown through the negative effects of the aromatase inhibitor on the weights of the testis, prostate, live and dead and abnormal sperm, and sexual behavior. Sage extract, but not flax seed, has benefit effects on the defect induced by aromatase inhibitor letrozole  both flax seed and sage do not produce positive effects on sexual behavior .

Abstract: 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.

Abstract: 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.

Abstract: Abstract This paper involves a determination of paracetamol using less environment harmful reagent; the hydroxy analog of the pharmaceutical naproxen replaced a chemical reagent in which it is used as a coupling agent for the diazotized p-aminophenol (the hydrolysis product of paracetamol), the paper offers a determination of an analgesic paracetamol in the presence of high content of another analgesic. Paracetamol azo-dye exhibits maximum absorption at 500 nm. Beer's law is obeyed over the concentration range from 10 to 650 µg/20ml, (i.e. 0.5-32.5 ppm) with a good sensitivity (molar absorptivity 1.2x104 l.mol-1.cm-1), good precision (RSD better than ±0.275%) and high accuracy (relative error less than + 0.77%), Sandell's sensitivity index is 0.0124µg.cm-2, the limit of detection (LOD) is 0.0030 µg/ml and the limit of quantitation (LOQ) is 0.0101 µg/ml. The method has been successfully applied for determination for paracetamol in dosage forms and its already applicable for the determination of paracetamol in presence of naproxen.

Abstract: A simple and accurate spectrophotometric method for the estimation of aniline in various water samples was done. The method was based on the condensation reaction of acetyl acetone-formaldehyde(AC-FA) reagent with aniline. to produce a yellow colored product, with maximum absorption at 417 nm, which has good stability at room temperature and it is very soluble in water (the medium of reaction). Beer's law is applied in the concentration range of 2.5 to 50 µg. ml-1 of aniline with a molar absorptivity 3.864×103 l.mol-1.cm-1 and Sandell's sensitivity index 0.0241 µg.cm-2 , a relative error of – 0.51 to +4.15 % and a relative standard deviation of ±0.78 to ±1.28% depending on the concentration level. The study also included the effect of organic compounds on the recovery of aniline in water samples. Aniline is the simple type of primary aromatic amines as it enters into many industrial fields and is considered as an important material. Aniline regarded as major pollutant of water, thus, its estimation was studied in different samples of water such as river, tap and Zamzam well waters.

Abstract: 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. Keywords: allelopathy, Field capacity, Ascorbic acid, wheat.

Abstract: Dialysis is used when the patient's kidneys can no longer perform their functions normally; it is a treatment that performs the functions of natural kidneys. Most patients begin dialysis when their kidneys have lost 85-90% of their ability to work naturally and they have to depend on dialysis for the rest of their lives, is called end –stage renal disease (ESRD). Infection in patients with end stage renal disease (ESRD) is usually treated with hemodialysis (HD) or peritoneal dialysis (PD). End stage renal disease a major cause of morbidity and mortality, in order to assess the fungal growth at hemodialysis and peritoneal dialysis unit a descriptive study was conducted at hemodialysis and peritoneal dialysis units in Hawler teaching hospital, from 15th of January to the end of May 2017;the study also includes the access sites and peritoneal catheter site. Factors that affected the access site among dialysis patient in the hospital. Sample of 63 patients, who were attending to the dialysis unit at time of the data collection, had been taken; in addition to that swab samples had been gathered from access site and peritoneal catheter site. The results of the study revealed that the fungal growth was positive at dialysis access sites, where the total percentage was 84.1% and that of peritoneal catheter site was 15.85%. In these unites, different types of filamentous fungi and yeasts had been successfully isolated.
