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 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.

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.

DOI: 10.33899/edusj.2020.127904.1101

In this research new compounds containing quinazolin-4(3H)-one nucleus linked to heterocyclic moieties were synthesized using ethyl (4'-oxoquinazolin-3'-yl) acetate (2) as a synthon. This compound was synthesized via 4-quinazolinone's (1) reaction with ethyl chloroacetate in the existence of K2CO3 as a base and acetone as a solvent. The ethyl α-(4'-oxoquinazolin-3'-yl) acetate (2) was converted to the corresponding hydrazide through its reaction with hydrazine hydrate (85 %). Compound (3) was reacted with two of acyl chlorides to synthesize the diacyl hydrazine compounds (4,5). The compound (5) was cyclized to the corresponding 1,3,4-oxadiazole (6) in presence of phosphorous oxychloride. The formyl derivative (7) of the hydrazide (3) was synthesized via its reaction with formic acid and consequently cyclized by phosphorous oxychloride to the corresponding 1,3,4-oxadiazole (8). The hydrazide (3) was also converted to the thiosemicarbazide derivative (9) by its reaction with ammonium thiocyanate under acidic conditions. Whereas other substituted thiosemicarbazide derivatives (10-12) were synthesized by the reaction of hydrazide (3) with organic isothiocyanate compounds. The resultant compounds (11, 12) were cyclized under basic conditions (4% sodium hydroxide solution) to give 1,3,4-triazole-2-thiole derivatives (13,14), whereas the cyclization of compounds (10-12) was performed under the acidic medium (conc. H2SO4) to give 2-substituted amino-1,3,4-thiadiazoles (15-17). On the other side, the hydrazide's (3) reaction with isocyanate compounds affords the semicarbazide compounds (18,19). These compounds were cyclized under the basic condition to afford 1,3,4-triazol-2-ol compounds (20,21). The structures of the synthesized compounds were corroborated depending on the physical and spectral data.

The face is the most critical component which is clear on first sight for an individual. Delicate tissue of the face alongside the fundamental dentoskeletal tissues portrays the facial attributes of a person. Social affirmation, mental well-being, and self-esteem of an individual are related to physical appearance. Strikingly, facial properties are regularly packed in profile. Orthodontic assurance and treatment orchestrating are continuously being established on profiles rather than basically on Angle's concept of molar relationship. It was seen that particular skeletal exact guidelines, proportion of constitution of the delicate tissue, and facial solid position can affect the assessment of the profile.
One of the uncommon challenges in orthodontics is the treatment orchestrating and the leading body of orthognathic careful cases. These cases require a mix of both orthodontics and orthognathic medical procedure to accomplish an even impediment, appropriate function, and agreeable facial feel. Early analyze of malocclusion is exceptionally helpful to get legitimate teeth straight. Thusly, in this paper we built up a straightforward PC supported program that could help foreseeing teeth impediment. In other word, we take an image of individual and order it into one of the three primary types Class I, Class II, and Class III and predict the after all treatments of Class II and Class III. This study gives information which can be used in treatment orchestrating by authorities, for instance, orthodontists, prosthodontists, plastic specialists, and maxillofacial experts, who have the ability to change the delicate tissue facial highlights.

ameer albyatei; Issa Zainalabddeen assaflly

DOI: 10.33899/edusj.2020.128376.1112

Hydrogen adsorption and storage on nickel- activated, pure graphene and boron-doped graphene was study using density functional theory simulations based on generalized gradient approximation methods (DFT-GGA). It was found that the nickel atoms tend to clustering on the surface of pure graphene due to the high cohesive energy of nickel compared to the energy of nickel binding to the surface of pure graphene, which decrease the storage capacity of hydrogen. It was also found that the storage capacity of seven hydrogen molecules on pure and activated graphene with a nickel atom is equal to (10.2 wt.%) With an average binding energy (0.27 eV), and the storage capacity for the same number of hydrogen molecules is (11.3 wt.%) With an average binding energy (0.22 eV), This indicates that the adsorption process will take place at ambient conditions. The process of inoculating graphene-doped boron and nickel activating is an effective strategy for improving the average binding energies and the storage capacity of hydrogen molecules in the graphene nanostructures.

blood cells and platelets in mice . 20mg/kg/day of apple cider vinegar seven days after hydroxy urea was administered produced no improvement in red blood cells and white blood cells and platelets counts.
The administration of apple cider vinegar with hydroxy urea produced significant (P<0.05) increase in red blood cells and white blood cells while platelets not recovered to normal .
The effect of hydroxy urea in mice on protein was observed as depressant effect significantly (P<0,05) on total protein adecrease in albumin and globulin .
The administration of apple cider vinegar seven days after hydroxy urea produced no significant effect on globulin and albumin , yet the total protein increased but not significantly .
The administration of apple cider vinegar at the same time with hydroxy urea significantly increase total protein and globulin , while no change on albumin level .
The results in this study indicate that apple cider vinegar has a protective effect on bone marrow from depressive effect of cyto toxic drug hydroxyurea .

This work presents the study of the effect of the static pressure on the propagation of laser beam in the fibers. Three types of fiber have been used in this studies; multimode & step index fiber, Plastic Clad Plastic (PCP) with and with-out jacket and Glass core fiber (bare core). Normal pressure of rang (0 ~ 1300 ) bar were applied on a section (20 cm) length of fiber.
The variation of power attenuation as a function of time during the applied pressure were also investigated .The sensitivity of each fiber was determined when used as a fiber optical pressure sensor.
The results show PCP with jacket gives poor response to the pressure up to 500 bar, while glass core fiber fail as a sensor when the pressure is 1300 bar. PCP with-out jacket show two times sensitivity more when compared with other fiber under the same pressure used in this study.

The study was conducted in order to create the best conditions (physical and chemical factors) that necessary for the growth of the Bacillus subtilis and its production of the Xylanase enzyme.
The results include isolation and diagnosis of (40) isolates of bacteria: Bacillus subtilis obtained from (30) soil samples and study the effect of some physical factors (period and temperature of incubation, pH of the medium, ventilation) on bacterial growth and its production of an Xylanase enzyme. The results showed that best growth and its production of the enzyme was obtained when the incubation is (48) hours and the temperature (30) Co , pH of the medium (7) and incubation with shaking at (200) rpm where the optical density value of bacterial growth was reached (0.25) and activity of the enzyme product was (3.41) unit / ml. The effect of some chemical agents (carbon and nitrogen source for medium) on bacterial growth and its production of an Xylanase enzyme and the results revealed that the carbon source (Xylan) gave the best growth and production of the enzyme compared with other of carbon sources (Starch, Cellulose, Xylose, Glucose, Sucrose, Maltose, Lactose), where the optical density value of growth was (0.25) and the enzyme activity (3.41) unit / ml. Regarding the effect of the nitrogen source (organic and inorganic) in medium on growth and production of the enzyme, the results showed that the best bacterial growth and the production of an Xylanase enzyme occur when organic nitrogen sources (Peptone, Beef extract, Yeast extract, Casien) were supplemented in the medium compared with inorganic nitrogen sources (KNO3, (NH4) 2SO4, NH4NO3, NaNO3). Peptone and Yeast extract were the best nitrogen sources for stimulation of bacterial growth and the production of the enzyme with optical density value of growth reached (0.29 , 0.286) and the enzyme activity was (3.92 , 3.9) unit / ml.
