It comprises the Pade' Approximation Method (PAM) and the Sumudu Transform Method (STM).The Sumudu Transform Pade' Approximation Method (STPAM) enhances the accumulation rate of the truncated Maclaurin series by stratifying the Pade' method in the Sumudu transform method chain solution. The Caputo's fractional derivative was employed. It is necessary for simulating issues with non-local features and phenomena that account for interactions in the past. The Caputo fractional operator is more adaptable for analysis and can handle initial and boundary value issues. The principal objective of the study is to use the Sumudu Transform Pade' Approximation Method (STPAM) to solve fractional models that arise in physics. We solved fractional physical models using the Sumudu transform method (STM) and compared the results to the exact solutions and the approximate Pade' approximation method (PAM) to assess the quality of the Sumudu Transform Pade' Approximation Method (STPAM). The findings highlight STPAM's advantages, including its ease of use, effectiveness, universality, cleanliness, packability, quality, and clarity.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"36 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140082640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural, morphological, and elemental composition of the thin films has been analyzed using XRD, SEM, and EDXS, respectively. The electrical conductivity and Seebeck coefficient of (PbS) 1-x (Zn) x film of 200 nm thick were determined and discussed. Thin films' electrical conductivity increased with temperature and film thickness. Pure PbS films manifested a positive Seebeck coefficient value indicating a P-type semiconducting behavior. The appearance of negative S values in Zn: PbS films could be assigned to the increase in electron concentration provided by Zn-doping and refers to the change of the conduction to n-type one. Pure films possess a high majority carrier concentration of 8.07×10 18 Cm -3 . Zinc-metal-doped lead sulfide thin films were tested as NH 3 gas sensors with 150 ppm of target gas concentration. The sensitivity of the PbS sensor to NH 3 gas was determined at various gas concentrations ranging from 50 to 150 ppm. The gas sensitivity increased as concentrations increased. The best-attained results of 93% and 174s & 310s for sensitivity and response & recovery times respectively, were obtained by (PbS) 0.95 (Zn) 0.05 at RT.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":" 1098","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140091741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To examine the effect of nitrites on the liver of male albino rats that were affected by nitrite dosages, and then to evaluate the ameliorative effect of vitamin C on the liver of male albino rats, this study intends to measure the nitrite concentrations in groundwater in Sohag governorate, Egypt. 60 albino adult male rats were placed into 4 groups, each group contains 15 animals: T 1 : standard nutrition (Control group), T 2 : Drinking water containing (>0.2 mg L -1 nitrite) group. T 3 : Sodium nitrite (300 mg/kg of body weight) group, T 4 : Sodium nitrite followed by vitamin C (300 mg/kg of body weight) daily for 3 months. At the end of the experiment, all rats were sacrificed to collect blood samples and then evaluated aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), albumin, total antioxidant capacity (TAC), and catalase, which showed a significant difference between animal groups especially elevation of hepatic parameters and decrease of antioxidant parameters in T 3 .

Nevertheless, additional research is required for a comprehensive understanding of its physicochemical properties and how they can be optimized for specific applications. The current study employed different analytical methods to examine the effects of varying exposure durations of PAW generated using air as a working gas (ranging from 0 to 15 minutes) on the temperature, electric conductivity (EC), contact angle, pH, H 2 O 2 , and NO − 2 measurements of PAW. Additionally, the study explored the effects of PAW storage at a temperature of -20°C and the stability of pH, hydrogen peroxide (H 2 O 2 ), and nitrite anion (NO - 2 ) levels over a period of up to 20 days after its production. The results clarified that the PAW contains reactive oxygen (ROS) and nitrogen species (RNS), specifically H 2 O 2 , and NO − 2 , which can be stored for at least over 20 days at -20°C without significant changes in concentration. Plasma treatment increases the conductivity of water over time, and the pH decreases with prolonged exposure. The study provides valuable insights into the diverse applications of PAW in distinct research and industrial domains.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140091631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mass spectra for [Cu(HL)(P)(CH3COO)2]H2O complex were studied. Also, pH stability for the CuPL chelate was estimated by employing a spectrophotometric analysis. The observed data revealed that (HL and P) ligands behaved as neutral bidentate ligands with NN donation sites. An octahedral geometry for the CuPL complex was proposed based on spectroscopic data. The thermogravimetric study was used to investigate the metal complex temperature stability and deterioration. A theoretical investigation of the Cu(II) complex was performed with the DFT/B3LYP computational method. DFT calculations better understand molecular mechanisms that could not be elucidated experimentally where the energy gaps and other key theoretical parameters were calculated. The vina dock mechanisms and affinities of Cu (II) complexes for (PDB ID: 3cku), (PDB ID: 2vf5), and (PDB ID: 5IJT), receptors were also investigated. The mixed ligand complex was evaluated for antimicrobial and anticancer efficacy against three species of bacteria, fungi, and cancer cell lines.

The well-cut diffusion technique was employed to ascertain the level of activity. The determination of minimal inhibitory concentrations (MIC) and minimal bacterial concentration (MBC) was conducted using the dilution method. These concentrations were assessed against Enterococcus faecalis ATCC 29212, Pseudomonas aeruginosa ATCC 9027, Aeromonas hydrophila ATCC 13037, and Staphylococcus aureus ATCC6538. The antibacterial potential of the crude extract obtained from a mixture of methanol/dichloromethane was 10.0 for S. leptoclados and ranged from 8.0 ± 0.58 to 14.0 ± 0.65 for S. ehrenbergi , and 10.0 ± 0.46 to 24.0 ± 0.68 for D. hemprichi . The D. hemprichi extract showed the highest antimicrobial activity which was carried out through MIC and MBC testing. Additionally, a partial characterization of these substances was conducted utilizing (GC-MS). The findings indicated the presence of varied bioactive substances, however, cis-vaccenic acid was considered the major compound in this species.
