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).

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.

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.

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.

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 .

The gradient energy coefficient () has a main function in extracting the polymers properties to help us to innovate and manufacture new polymers and different process like coating, wetting, foaming, adhesion operations. The Cahn-Hilliard (CH) theory [1], represents the free energy profile of polymer surfaces or interfaces.  Considers the free energy profile of polymer surfaces or interfaces as inhomogeneous which has more than one phase. On the other hand, it has been used the Freed Bawendi contribution in conjunction with Cahn-Hilliard in treatment with architecture structure for polymers [2]. While Simha-Somcynsky (SS) theory describes the thermodynamic properties of both low and high molecular weights in terms of occupied site fraction (y) [3].  This study has been examined in the range of (313 -473) K temperatures and up to about (150) Mpa pressure. The quantitative success of our study is clearly appeared in the minimum and maximum deviations in the volume is 0.036 and 0.128 respectively.

Infections caused by bacteria are common in infants and neonates. Some of these infections are severe and usually carry high risk of fatal complications such as septicemia and / meningitis if left un-treated. Very often, the diagnosis of these infections is clinical as well as laboratory diagnosis to determine the type of bacteria in body fluids such as urine, stool, blood and CSF. The present study aims to isolate and identify the bacteria responsible for some types of severe infections in neonates such as urinary tract infections (UTI), gastrointestinal tract (GIT) infections and bacteremia in West bank of Mosul city and test their susceptibility to different antibiotics. Twenty-seven (27) samples from blood, 28 from urine and 6 from stool were collected from neonates admitted to "Mosul General Hospital" in West Bank of Mosul city in the period between 1/7/2018 to 1/9/2018. Our results indicated that Staphylococcus aureus was the most common bacterial isolate in blood (81%), whereas both Staphylococcus aureus and Esch. coli were common in urine (48% and 43% respectively) followed by Proteus and Pseudomonas aeruginosa (4.5 % each). Both Staphylococcus aureus and Esch. coli  were highly sensitive to amoxiclav (83% for and 100% respectively), levofloxacin (88% for Staphylococcus aureus and 100 % for Esch.coli) and meropenem (100% for both Staphylococcus aureus  and Esch .coli). However, both of them were highly resistant to ampicillins (100%) and 3rd generation cephalosporins. Although meropenem is effective, it's use should be selected and restricted to highly resistant cases to avoid the emergence of early antibiotic resistance.

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.

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.

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 chemical constituentis of three types of bituminous materials found in different conditions in Mishraq sulfur Mine was studied. The FTIR spectroscopy showed reduce in the length of hydrocarbon‏ chains from the intensity of paraffinic bands in bitumenous materials of Frasch sulfur Mine (BM) compare with natural bituminous materials (NB) and Bituminous materials which extracted in-depth about 200 m without exposing to Frasch process condition (BB). The percentage of asphaltene in (MB) which increases dramatically is found 63.64% compared with (BB) and (NB) which 37.37% and 14.28% respectively and a similar decrease in percentage petrolene (maltene) . A percentage of n-hexane fraction by silica gel chromatography of petrolene (MB) is 18.49% compared with (BB and N.B) are 25.06 % and 47.05 % respectively while the cyclohexane fractions of petrolene MB are four-time of N.B and three-time of B.B .
From all results, we conclude that a reaction has occurred between sulfur and bitumenous materials especially hydrocarbon chains of Aromatics and naphthenic rings in sulfur well during Frasch process which leads to an increase in asphaltene percentage and decrease of petrolene.

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.

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.

Abstract:
This study includes calculation of the potential stickiness (S*) and apparent activation energy (AAE) by the adsorption process of some aromatic carboxylic acids using sand (clay) as a new adsorbent material. This clay was collected from dust storms coming to the city of Mosul. The obtained results showed that physical adsorption which is achieved by applying the modified Arrhenius equation through the values of (S *) and (AAE) which have low values and bear a negative charge is preferable Adsorption process occurs in two-step mechanism. The effect of the concentration of the acidic solution, temperature and the substituted groups SO3, NO2, OH, NH2 on the aromatic ring) was studied to clarify the nature of the association between organic carboxylic acid anions and inorganic metal oxides to form a complex surface model. The study concluded that the values of (S *) for all acids were less than one and they were more than the value of zero. Also, the values of (AAE) gave an indication that the adsorption process is exothermic and spontaneous. The presence of water molecules and (H+) ions in solution is very important to change the nature of the clay surface.

Abstract
A new complexes of some transition metal ions (Co(II),Ni(II),Cu(II)) and non transition metal ions (Zn(II),Cd(II)) with a number of Schiff bases obtained from the condensation of some amino acids valine and serine with (Indol-3-carboxy aldehyde) have been prepared. All the prepared complexes have been characterized by elemental analysis(M), molar conductance, magnetic susceptibility infrared and electronic spectral. The complexes were classified as:
A- mononuclear complexes.
1- Complexes with the formulas [ML(CH3COO) (H2O)2].
2- Complexes with the formulas [ML(CH3COO)] H2O.
B- Di nuclear complexes.
Complexes with the formulas [M2(L)2(CH3COO)2] .2H2O.
M= Co(II),Ni(II),Cu(II),Zn(II)Cd(II).
L= Indol-3-carboxy aldehyde valine imine, Indol-3-carboxy aldehyde serine imine
The physical measurements showed that the prepared complexes may have a tetra coordinated (tetrahedral or square planer) and hexa-coordinated (octahedral) structure and that all the prepared complexes were non electrolyte.
