This work discusses the geologic setting of Wadi Kab Ar Rakab Al Shamali area in the South Eastern Desert of Egypt, and the distribution of the natural radionuclides and assess the radiological hazard resulting from different rock types in the area. The background radiation levels, human exposure, dose rates, and potential radiation effects on the environment are all studied. The field geological investigation of the different rock units, with orientations to their mode of occurrence, common relationships, petrographic study and regional structure indicated that the investigated area is covered by Late Proterozoic igneous and metamorphic rocks. These basement rocks are included metavolcanics, metagabbros , granodiorites , younger gabbros, monzogranites, syenogranites, alkaline granites and alkaline syenites. The studied rock types have low uranium and thorium contents. The yearly effective dose, external absorbed dose rate in both indoor and outdoor environments, internal absorbed dose rate in both indoor and outdoor environments, and radium equivalent activity are all estimated. The investigation indicates that all the environmental impacts dose rates values in the studied rocks are lower than the public permissible values in these rocks and they are within the safety range for the public and workers. So, these rocks are safe for the building materials and can be used as ornamental stones.

Background High prevalence of Hepatitis C virus (HCV) in Egypt considers it as the major cause of hepatocellular carcinoma (HCC). So, several attempts have been used to predict HCC but still need more. In this regard, the predicting abilities of superoxide dismutase (SOD) and catalase (CAT) activities as well as total antioxidant capacity (TAC) were tested for estimating chronic hepatitis C (CHC)-mediated HCC. Patients and methods Blood samples from 79 patients (23 CHC and 56 HCC) were withdrawn to estimate these antioxidants and the routine analysis markers. Beside 15 healthy volunteers were included Results The medians of SOD activity and TAC values were significantly elevated in sera of HCC patients with positive correlation (P<0.0001, r=0.334) when compared with those of either CHC or healthy controls (P<0.0001). On contrary, the median of CAT activity was significantly lowered (P<0.0001) with negative correlation with SOD activity (r=-0.146, P<0.04). Stepwise logistic regression analysis of the last three markers produced a score; named "Antioxidants-diagnostic" which increased the AUCs values and their diagnostic activities (P<0.0001). By combining the three marker values with that of Age-platelet index (API) produced a score named "Antioxidants-API". Also, by combining them with that of the routine analysis values produced a score named “AAI-antioxidants”. In each case the AUCs values were enhanced when compared with those of its native antioxidants (P<0.0001). Conclusion The assessment of these antioxidant activities and their combination in the last three scores can enhance their activities to more precisely predict HCC patients among CHC ones and control individuals.

Determining the spatio-temporal manners of urban sprawl is considered one of the most influential challenges in evaluating the present and future directions of the urban expansion issue. Random growth is considered as a kind of meeting the needs of the human being and expressing the achievement of its basic requirements when the state is unable to solve them. This paper aims to assess the sprawl and growth dynamics between 2010 and 2020 in Al-Baydah City, Libya using remote sensing and GIS techniques. Three Landsat TM, ETM+, and OLI images dated 2010, 2015, and 2020 were used to generate urban maps of the research area. The chi-square test and urban expansion intensity index (UEI) were used to assess urban growth patterns in the study zone. The results of the study confirmed that urban growth in the city has increased from 17.7 km2 in 2010 to 35.9 km2 in 2020, indicating that the city's expanding intensity index has risen as well. The results displayed that Al-Baydah city has unbalanced urban growth and its urban development had a high freedom degree during the period from 2010 to 2020.

Infections of Urinary tract are one of the significant to recommending antibiotic utilization. To involve the most perfect antibiotic for treatment patients, solid and ongoing information about the study of disease transmission and antibiotic resistance of pathogenic bacteria should be accessible for clinicians. So, the normal checking in every nation is required. The points of our review to explore the uropathogenic bacterial variety and antibiotics resistance rates of pathogenic bacteria at the Mansoura Oncology Center (Egypt, Mansoura city) from first October, 2019 to 30th September, 2020 and furthermore to add to checking and topographical variation of treatment by antibiotic. 150 urine samples by aretrospective analysis at Mansoura Oncology Center was processed according to the perfect protocol of urine analysis. Current results were prepared to obtain the prevalence of Urinary tract infections, antibiotics bacterial resistance, time over evolution, and multidrug resistance rate. Bacteria collected from 100 samples were the Escherichia coli and Klebsiella pneumoniae were to be the most identified with 42.0%, and 35.0% respectively. Other main detected species were Enterococci (9%), Pseudomonas (5%), Proteus mirabilis (4%), Citrobacter (2%), Breundimona (1%), Raoultella (1%), and Kluyvera cryocre-scens (1%). Resistance tests to antibiotics indicated K. pneumoniae was more resistance to Cefotriaxon 39.3%, while E. coli was resistant to Ciprofloxacin and Levofloxacin by 41.8%. The variety of some uropathogenic bacteria acquired had all the reserves of being resistant to various antibiotics. Ready faciing by arestorative impasse and the coming of bacteria with multi-resistant, recognizing explicit causes also is significant to adjust antibiotic treatment.

Adsorption of indigo dye onto amidoximated acrylonitrile /Na-Y-Zeolite composite had been evaluated in aqueous-solutions studying different parameters namely, period of the experiment, pH, adsorbent dosage and thermal effect on the experiment. Different properties of amidoximated acrylonitrile/sodium-Y-Zeolite composite as forier-transformation IR spectroscopy, X-rays deffraction had been investigated. Langmier and Frendlich sorption imitations had been utilized for describing equilibrial isotherm. In addition, evaluation of the activating force of sorption has been carried out regarding the sorption of indigo dye on the surface of amidoximated acrylonitrile/sodium-Y-Zeolite composite. Kinetics information of the reaction were also studied. These experimentally obtained information was nicely compatible and consistent with the pseudo-second-order kinetics for adsorption of indigo dye. The activating force (Ea), difference in liberated energies (∆G), entalpy (∆H) and enthropy (∆S) of sorption methodology had been determined regarding the sorption of the indigo dye via amidoximated acrylonitrile/sodium-Y-Zeolite composite. The thermodynamics of the sorption proved that the process had been both spontaneously and endothermically happening. The results indicated that amidoximated acrylonitrile/sodium-Y-Zeolite composite would be successfully applied as efficient, reproducible, and inexpensive adsorbent regarding the sorption of indigo dye from industrial wastewaters.

The pollen morphology of 36 woody species from the New Damietta City, Egypt. Belonging to 20 families of angiosperms, distributed in eighteen dicots and two monocots were investigated. The pollen grains were acetolysed, measured, described and illustrated under light microscopy (LM). Examination of these families revealed great pollen diversity in their qualitative and quantitative characters. The results revealed 58.3% of species with prolate-spheroidal pollen, 16.7% with oblate-spheroidal pollen, 16.7% with subprolate pollen, 5.6% with prolate pollen and 2.7% with suboblate pollen. Tricolporate apertures accounted for almost half of apertures types; triporate, monocolpate, tricolpate, tetra- to penta-porate, tetraporate, pantoporate, inaperturate, tetracolporate and spiral aperture representing the remainder. Exine ornamentations ranged from psilate (33.3%), reticulate (27.7%) to micro-reticulate, scabrate, granulate, echinate each represents (2%) and clavate, verrucate, rugulate, striate, psilate-perforate, clavate-reticulate made up (1%) for each type. On the basis of pollen units, number and type of apertures, exine patterns were great diagnostic significance among the examined taxa. Six major pollen types and nine subtypes included in two groups (polyads and monads) were recognized. Description of pollen types, LM micrographs and a key for identification of the investigated taxa are provided.

Proteases are the major enzymes that have been used widely in health, food, and nutritional supplement fields. Rare actinobacteria are considered a new resource for proteolytic enzyme activity. Rare actinobacteria are used to be isolated from marine and have been studied under restricted limits. The strain used in this study was identified as Lentzea sp. which was successfully isolated from the soil at the Faculty of Science, Damietta, Egypt. It was subjected to gelatin liquefaction as primary screening for gelatinolytic activity. Based on this study, the best gelatinolytic (gelatinase) activity was noticed within 8 days at 37oC (17.59 U/ml ±0.06). The maximum activity was obtained at pH 9 (28.33 U/ml ±0.04) and agitation speed of 150 rpm (29.10 U/ml ±0.04). Upon carbon and nitrogen source optimization, the basal medium of combination between gelatin and peptone produced maximal gelatinase activity (29.12 U/ml ±0.06) and it was found that 10% sucrose was the best carbon source that produced maximum gelatinase activity at (30.17 U/ml ±0.05).
