East Minia is considered as one of the most promising areas for the establishment of numerous sustainable development projects. The Middle Eocene Limestone aquifer is the main water source needed for the establishment of these projects. Therefore, 32 collected samples from different wells and chemically analyzed to determine the suitability of that water for drinking and irrigation, as well as mentioned to the various factors controlling the water quality through the application of hydrochemical diagrams and statistical analysis. TDS value of the studied water samples was ranged from 271 to 2328 ppm which indicates that nearby is 93.8% of the investigated water samples are acceptable for drinking uses, while total hardness value ranged from 32.19 to 1035.44 which indicates that there is 93.8% of the studied groundwater samples are suitable for domestic uses. Statistical analyses, Gibbs and End-member diagrams indicate that the water-rock interactions, geochemical process (Redox), besides anthropogenic activities are the essential contributor to the investigated groundwater chemical composition. Thus, the studied water is suitable for irrigation purposes based on the calculated sodium hazards and salinity.

A condensation between 2-sulfanilamidopyrimidine and a p-toluidine dimer of cyclodiazadiphosphetidine resulted in the formation of a new ligand, 2,2,4,4-tetrachloro-1,3-di-[p-tolyl]-2,4-di-[N-(pyrimidin-2-yl) benzenesulfonamide]-1,3,2,4-diazadiphosphetidine, (H2L). We investigated the chemical behavior of the newly prepared ligand was investigated by treating it with some chosen metal ions at a stoichiometric ratio of 1:2 (L:M), where M = Fe(III), Fe(II), Cu(II), Zn(II), Cd(II), and Ag(I), to provide colored complexes with accepted yields. Then, we characterized the ligand and related complexes using spectroscopic and analytical techniques. Investigations revealed that the geometrical structure of the complexes was octahedral, except for the silver complex was tetrahedral. From the spectral analyses, we observed that the ligand coordinated with metal ions through the enolic OH of the sulfonamide group and pyrimidine-N of the pyrimidine ring. The molecular geometries have also been optimized by using density functional theory (DFT-B3LYP) methods. Additionally, molecular electrostatic potential (MEP), and chemical activity parameters, including chemical hardness, electronegativity, softness, and other parameters have been investigated. We also tested H2L and its metal complexes for their ability to inhibit the growth of bacterial cells against different types of microorganisms and cancer cells against two different cell lines: MCF-7 and HTC-116. Accordingly, the recently synthesized ligand (H2L) and its metal complexes exhibited good antimicrobial and antiproliferative actions. Hence, we finally conducted molecular docking of the ligand and its complexes to verify their drug ability.

Discrete models are particularly useful for modelling population dynamics when the population size remains small over several generations or when it is relatively constant within a single generation. We focus on finding effective solutions to the challenges posed by such populations. In our research, we have successfully used qualitative analytic techniques to study a three species model. It is important to consider the reproductive process and other population dynamics as happening in real-time, even for species with unclear reproductive seasons. While the delay technique has introduced some complexities, we have identified sufficient conditions to address them. Our study examines the global stability of a three species ecological model that does not consider delayed intraspecific competition. We analyze a delayed Lotka Volterra system, which demonstrates global stability when the interaction matrix is effective. We present numerical simulations to illustrate the theoretical results of the delay differential equation. Since delay differential equation models are always challenging to solve, we propose the use of JiTCDDE (just-in-time compilation for delay differential equations) of the DDE integration method to solve the dynamical three species models.
当种群规模在几代内保持较小或在一代内相对恒定时，离散模型对于建模种群动态特别有用。我们的重点是寻找有效的解决办法，以应对这些人口构成的挑战。在我们的研究中，我们成功地使用了定性分析技术来研究三种模型。重要的是要考虑到生殖过程和其他种群动态是实时发生的，即使对生殖季节不明确的物种也是如此。虽然延迟技术引入了一些复杂性，但我们已经确定了解决这些问题的充分条件。我们的研究考察了一个不考虑延迟种内竞争的三物种生态模型的全局稳定性。我们分析了一个时滞Lotka Volterra系统，证明了当交互矩阵有效时系统是全局稳定的。我们给出了数值模拟来说明延迟微分方程的理论结果。针对时滞微分方程模型求解难度较大的问题，提出了采用jit -in-time compilation for delay differential equations的DDE积分方法求解动态三种模型。

Microbes that are resistant to antibiotics are becoming a severe threat to global healthcare system. The well possible alternative to the possibility of medication resistance is the incorporation of natural remedies with considerable antimicrobial property in the therapeutic approaches of bacterial illnesses. Methicillin-resistant Staphylococcus aureus (MRSA), Enterococcus faecalis (E. faecalis), Escherichia coli (E. coli), Klebsiella pneumoniae (K. pneumoniae), Pseudomonas aeruginosa (P. aeruginosa), Acinetobacter baumannii (A. baumannii), Proteus mirabilis (P. mirabilis), Stenotrophomonas maltophilia (S. maltophilia) were isolated from 50 clinical specimens taken from patients admitted to Al-Zahraa University Hospital and Cairo Specialized Hospital from January 2016 to June 2016. Antimicrobial impacts of various solvents including (hexane, ethyl acetate, chloroform, and aqueous) were screened against multi-drug resistant (MDR) strains isolated from clinical samples. Echinacea Purpurea ethyl acetate fraction showed the most promising antibacterial activity versus bacterial clinical isolates with inhibition zone range 16.8-22.7 mm, and MIC range of 15.63-250 µg/mL, whereas other fractions were found to exhibit lower inhibition zones and higher minimal inhibitory concentration (MIC) values than ethyl acetate fraction against MDR strains. None of fractions have antibacterial action versus S. maltophilia. Electron microscopic investigation of MRSA treated by E. purpurea ethyl acetate reveled its role in lysis of pathogenic bacterial cells. The ethyl acetate fraction of the E. purpurea was analyzed using LC–MS to screen various molecules present in the fraction of E. Purpurea ethyl acetate fraction showed promising antioxidant activity with IC50 = 14.24 ± 0.58 µg/m. E. Purpurea ethyl acetate fraction had CC50 value of 1145.97 μg/ml upon testing on Vero cells highlighted its minimal toxicity. The study's findings will be used to further in vivo elucidate the E. purpurea ethyl acetate fraction for potential medicinal purposes.
对抗生素具有耐药性的微生物正在成为全球卫生保健系统的严重威胁。在细菌性疾病的治疗方法中结合具有相当抗菌特性的自然疗法，是很可能替代耐药性可能性的方法。从2016年1月至6月在Al-Zahraa大学医院和开罗专科医院采集的50份临床标本中分离出耐甲氧西林金黄色葡萄球菌(MRSA)、粪肠球菌(E. faecalis)、大肠杆菌(E. coli)、肺炎克雷伯菌(K. pneumoniae)、铜绿假单胞菌(P. aeruginosa)、鲍曼不动杆菌(A. baumannii)、神奇变形杆菌(P. mirabilis)、嗜麦芽窄养单胞菌(S. maltopophilia)。筛选了不同溶剂(己烷、乙酸乙酯、氯仿和水溶液)对临床样品中分离的多重耐药(MDR)菌株的抑菌效果。紫锥菊乙酸乙酯部位对临床菌株的抑菌效果最好，抑菌带范围为16.8 ~ 22.7 mm, MIC范围为15.63 ~ 250µg/mL，而其他部位对MDR的抑菌带较低，最小抑菌浓度(MIC)值高于乙酸乙酯部位。对嗜麦芽葡萄球菌均无抗菌作用。紫红色E. E. purpurea乙酯对MRSA的电镜观察揭示了其裂解致病菌细胞的作用。采用LC-MS对紫荆荆的乙酸乙酯部位进行分析，筛选出紫荆荆荆乙酸乙酯部位中存在的各种分子，其抗氧化活性为IC50 = 14.24±0.58µg/m。紫荆乙酸乙酯部位对Vero细胞的CC50值为1145.97 μg/ml，毒性较小。该研究结果将用于进一步在体内阐明紫荆叶乙酸乙酯部分的潜在药用价值。

The current investigation tested Chitosan isolated from adult Vespa orientalis and Aiolopus thalassinus for its cytotoxic and anticoagulant effects. Chitosan was analyzed for its effects on human breast cancer cells (MCF-7), human liver cancer cells (HepG2) and lung fibroblast cells (WI-38) after being extracted and characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Also, the anticoagulant activity of extracted chitosan using activated partial thromboplastin time (APTT) and Prothrombin Time (PT) assays was investigated. Results showed that cytotoxic activity of both extracted chitosan samples recorded cellular viability of MCF-7 cell line equal to 17.99 and 9.53 % by V. orientalis and A. thalassinus extracted chitosan at 1000 μg/ml, respectively. At 500 μg/ml, the viability of the HepG2 cell line was recorded 54.95 and 20.76 % by V. orientalis and A. thalassinus, respectively. In addition, V. orientalis and A. thalassinus extracted chitosan showed non-cytotoxic effects against the WI-38 cell line at concentrations less than or equal to 250 and 125 μg/ml. On the other hand, the anticoagulant activity of V. orientalis extracted chitosan using APTT assay recorded 53.7 ± 0.01 second at 75 μg/ml, while A. thalassinus chitosan reached 58.91 ± 0.04 sec. at 75 μg/ml. Whereas anticoagulant activity of V. orientalis chitosan using PT assay recorded 12.16 ± 0.07 sec. at 25 μg/ml, compared with 14.37 ± 0.02 sec. for A. thalassinus chitosan at the same concentration. Based on these results, can be inferred that V. orientalis and A. thalassinus maybe considered as a source for chitosan with properties suitable for cytotoxic and anticoagulant activities.

The main purpose of this work is to detect reservoir characterization of Hammam Faraun member of Belayim formation at North El Morgan oil filed based on integration of petrophysical and sedimentological studies. The work-flow in this study integrates multiple data evaluation techniques and multiple data scales by using a comprehensive interpretation of the available conventional, advanced digital well log data (large scale) and core analysis data (small scale). The petrophysical work shows the hydrocarbon saturation, shale volume and effective porosity are varied along reservoir. The NMR logs shows various clay bound volume, capillary bound water volume and free fluid content along the reservoir. The sedimentological work done includes core sample description, core log and ditch cutting description, that helped to understand facies distribution along reservoir zones, depositional cycles recorded in reservoir zones, relationship between different rock type and understanding the heterogeneity of the reservoir. Integrated petrophysical and sedimentological work lead to divide Hammam Faraun reservoir in to three zones (Hammam Faraun B1, B2 and B3 zones) which have different reservoir quality, facies type and lead to understand the behavior and production performance of each zone along area of study. By using petrophysical and sedimentological results we can outline possible opportunity areas as well as generate depletion development plan for the field to help in increasing field production through drilling new development wells and water injection wells.
{"title":"RESERVOIR CHARACTERIZATION OF HAMMAM FARAUN MEMBER IN NORTH EL MORGAN FIELD GULF OF SUEZ, EGYPT","authors":"Ahmed Walaan, Alaa Mostafa, Mahmoud Hassaan","doi":"10.58675/2636-3305.1634","DOIUrl":"https://doi.org/10.58675/2636-3305.1634","url":null,"abstract":"The main purpose of this work is to detect reservoir characterization of Hammam Faraun member of Belayim formation at North El Morgan oil filed based on integration of petrophysical and sedimentological studies. The work-flow in this study integrates multiple data evaluation techniques and multiple data scales by using a comprehensive interpretation of the available conventional, advanced digital well log data (large scale) and core analysis data (small scale). The petrophysical work shows the hydrocarbon saturation, shale volume and effective porosity are varied along reservoir. The NMR logs shows various clay bound volume, capillary bound water volume and free fluid content along the reservoir. The sedimentological work done includes core sample description, core log and ditch cutting description, that helped to understand facies distribution along reservoir zones, depositional cycles recorded in reservoir zones, relationship between different rock type and understanding the heterogeneity of the reservoir.
