ENVIRONMENTAL FLOW AND CONTAMINANT TRANSPORT MODELING IN THE AMAZONIAN WATER SYSTEM BY USING Q3DRM1.0 SOFTWARE
Authors: Yu Li-ren , Yu Jun 
Published: July 2020

This paper reports a fine numerical simulation of environmental flow and contaminant transport in the Amazonian water system near the Anamã City, Brazil, solved by the Q3drm1.0 software, developed by the Authors, which can provide the different closures of three depth-integrated two-equation turbulence models. The purpose of this simulation is to refinedly debug and test the developed software, including the mathematical model, turbulence closure models, adopted algorithms, and the developed general-purpose computational codes as well as graphical user interfaces (GUI). The three turbulence models, provided by the developed software to close non-simplified quasi three-dimensional hydrodynamic fundamental governing equations, include the traditional depth-integrated two-equation turbulence model, the depth-integrated two-equation turbulence model, developed previously by the first Author of the paper, and the depth-integrated two-equation turbulence model, developed recently by the Authors of this paper. The numerical simulation of this paper is to solve the corresponding discretized equations with collocated variable arrangement on the non-orthogonal body-fitted coarse and fine two-levels’ grids. With the help of Q3drm1.0 software, the steady environmental flows and transport behaviours have been numerically investigated carefully; and the processes of contaminant inpouring as well as plume development, caused by the side-discharge from a tributary of the south bank (the right bank of the river), were also simulated and discussed in detail. Although the three turbulent closure models, used in this calculation, are all applicable to the natural rivers with strong mixing, the comparison of the computational results by using the different turbulence closure models shows that the turbulence model with larger turbulence parameter provides the possibility for improving the accuracy of the numerical computations of practical problems.

Background: Small scale sunflower oil industries are industries which extract oil from sunflower seed. Apart from its contribution to the economic development of the nation, during extraction process much dust concentration produced and respiratory symptoms are unknown. The aim of study was to assess dust exposure and associated respiratory health symptoms among small scale sunflower oil industries workers in Singida Tanzania. Methods: A cross sectional study was conducted and 233 participants were interviewed using a modified American Thoracic Society questionnaire to assess the respiratory health symptoms. A Side Kick Casella Pump was used to collect respirable dust from a sub sample of 66 workers from the sieving section. Results: Respirable dust exposure levels for mean, and Geometrical mean was 10.45 mg/m3 (SD 13.90) and GM=5.25 mg/m3 (GSD 0.51) respectively, and 46% of the dust samples (n=66) were above the TLV of 5 mg/m3. Logistic regression analysis between measured dust and respiratory symptoms found to be statistically significant. Higher prevalence of respiratory health symptoms were seen in those with cough (33%), cough with phlegm (46.8%) and wheezy (41.6%). Conclusion: The study concludes that, respiratory symptoms were high and dust exposure was above recommended levels of 5 mg/m3. We recommend use of appropriate RPE.

Published: July 2020

In this paper, we introduce the joint project of the Museo Egizio (Turin), the University of Basel, and the University of Liège entitled “Crossing Boundaries: Understanding Complex Scribal Practices in Ancient Egypt”, and provide a progress report for 2019. The project deals with Ramesside hieratic papyri of the Turin collection that stem from Deir el-Medina (c. 1350–1050 BCE), adopting a contextualised approach to this written material. Crossing the boundaries between disciplines, we aim to shed light on the life of a particular category of complex documents, labelled “heterogeneous” papyri, i.e., papyri combining on a single support texts (or drawings) belonging to different genres.

The ovarian histomorphometric in adult normal and unilateral ovariectomized Iraqi black goats (Age 7 months) was studied to evaluate the effect of laparoscopic unilateral ovariectomy of young goat (age 2-3 months) on other remaining ovary histologically. Ten young female Iraqi black goats were used in the study. The goats were divided randomly into two equal groups; young goats were left normal (group A) and young goats underwent to right laparoscopic unilateral ovariectomy (group B). All animals in both groups were left to reach adult stage at 7 months age, in which they underwent to removal their ovaries laparoscopically by using the harmonic scalpel. Operations were performed under general anesthesia by using of a mixture of xylazine and ketamine intramuscularly. The ovarian histomorphometric included; height of germinal epithelium and thickness of tunica albuginea, cortex and medulla were measured at adult stage for both groups. The study revealed a significant elevation (P<0.05) in thickness value of tunica albuginea, cortex and medulla in the right ovary compared with the left one in normal adult goat (group A). The left ovary in group (B) showed significant increase in the thickness value of tunica albuginea, cortex and medulla compared with those in similar (left) ovary in group (A) which indicated that the remaining ovary in group (B) showed compensatory action in increasing their histological structures measurements. The short operative time, no intraoperative and less postoperative complications referred to that the laparoscopic ovariectomy in goats could be performed successfully with this technique and by using of harmonic scalpel.

Authors: Ahmed Adnan Jawad 
Published: July 2020

Effect of different concentrations of Nisin, Potassium sorbate and Sodium chloride on the keeping quality of the locally produced soft cheese samples against the Staphylococcus aureus viability was conducted during November 2015/ May 2016. Staphylococcus aureus were isolated from 20(73.33%)out of 30 bovine and ovine locally produced soft cheese samples and their identification were confirmed based on the morphological, rapid biochemical reactions and serological properties. Staphylococcus aureus isolates that obtained by plating on the Chromogenic agar were further tested serologically. The highest significant (P<0.05) prevalence levels of Staph aureus were found in the cow's soft cheese samples 8/10(80%) followed by both ewe's and buffalo's soft cheese samples7/10 (70%) respectively. Three concentrations for each of Nisin, Potassium sorbate and Sodium chloride (50, 25 and 12.5 IU/ml), (0.4, 0.2 and 0.1%) and (10, 5 and 2.5) were used respectively. The minimum inhibitory concentrations of the Nisin and both Sodium chloride and Potassium sorbate against Staphylococcus aureus that were determined by the turbid metric technique were 50 IU/ml, 10% and 0.4% respectively. Mean values (log c.fu/ml) of the starting initial Staph aureus counts in the experimentally manufactured soft cheese samples decreased significantly (P<0.05) from 7.00±0.002 (log c.fu/ml) at 0 hour to 5.11±0.039 (log c.fu/ml) after 24 hrs of exposure to action of Nisin and Potassium sorbate inside the brine solution at 37°C. The bactericidal activities of Nisin and Potassium sorbate were more effective than either of them alone after 24 hrs. of exposure inside the brine solution at 37°C (reduction level approximately 3 log cycles), but the bacterial counts still were above the safe limit, which is required for the production of Staph aureus enterotoxin.

Published: July 2020

The objective of this study was designed to evaluate the possibility of repairing tracheal cartilage defect in dogs. 18 local breed dogs of both sexes was used in this study, they are allocated into 2 equal groups. A tracheal defect was induced in the cervical part of the trachea as a window about 3cm x 2cm in diameter. The defect was closed in 1st group by using polypropylene mesh and bone cement substance, while in 2nd group polypropylene mesh with fresh auto- bone marrow. Post-operative study including, clinical observation, gross pathology and histopathological evaluation was performed in all animals. The most important postoperative clinical observation was represented by subcutaneous emphysema at the site of operation in the 2nd group animals, which gradually disappeared within few days. Otherwise no other important complications was reported in both groups during the period of the experiment. The gross pathological changes and biopsy collection for all animals was done at 15, 30, 60 postoperative days. The gross examination revealed complete closing of the induced tracheal defect in all operated animals and a mild adhesion with the surrounding tissues. In both groups, the histopathological features was represented by newly granulation tissue formation and areas of hyaline cartilage degeneration and necrosis. The cartilage regeneration was showed only in 2nd group through by formation of new cartilage cells. In conclusion, it can use both techniques for reconstruction of tracheal defect in dogs but the auto bone marrow group was regarded the best due to improvement of the healing process. .

Published: July 2020

The study aimed to show the effect of experimental infection with E.coli O157:H7 on some liver and kidney function in adult rabbits. Twenty five domestic rabbits (males and females), aged 6-8 weeks and weighing 1500-2000g, had a negative fecal bacteriological culture of E.coli O157:H7 were used. The rabbits were randomly divided into two groups: infected group (15 rabbits), each animal was drenched orally with 1ml of Phosphate buffer saline containing (2×109CFU) of E.coli O157:H7, while the control group (10 rabbits) were drenched orally (1ml) of Phosphate buffer saline, the clinical signs were daily observed for 30 days, recording of body weight and blood samples were collected at (0, 3, 15 and 30) days for serum to evaluate biochemical tests including Alanine transaminase, Aspartate aminotransaminase and alkaline phosphatase, creatinine, urea and total serum protein. The results showed different clinical signs after inoculation, including diarrhea, lethargy, weight loss, inability to eat or drink, urine was cloudy or milky, while control group remains in normal condition. The serum biochemical tests in infected group showed a significant increase of three enzymes at 15, and 30 days, the highest values of Alanine transaminase; Aspartate aminotransaminase and alkaline phosphatase showed at 30 days post infection as compared with the control group. Serum creatinine and urea recorded a significant increase (P< 0.05) at 30 day post infection as compared with control group. However, total protein revealed a significant decrease in the infected group, and a significant decrease was noticed at 15 day post infection, while the control group showed an increase in total protein co-ordinated with increase of body weight and progressing age. This study concluded that the infection with E. coli O157:H7may cause changes in liver and kidney functions which were more sever at 15,30 days post infection.
On the Formation of a Bead Structure of Spark Channels during a Discharge in Air at Atmospheric Pressure
Authors: Tarasenko Victor , Beloplotov Dmitry , Burachenko Alexander , Baksht Evgenii 
Published: July 2020

The conditions for the formation of spark channels with a bead structure in an inhomogeneous electric field at different polarities of voltage pulses are studied. Voltage pulses with an amplitude of up to 150 kV and a rise time of ≈1.5 µs were applied across a 45-mm point-to-plane gap. Under these conditions, spark channels consisting of bright and dim regions (bead structure) were observed. It is shown that when current is limited, an increase in the rise time and the gap length does not affect the formation of the bead structure. It was found that an increase in the amplitude of voltage pulses leads to an increase in the length of beads. The appearance of the bead structure is more likely at negative polarity of the pointed electrode. The formation of spark channels was studied with a four-channel ICCD camera.
