Archaeometallurgical characterization of Greco-Roman copper-based and iron nails from Tel Abu Seify, North Sinai, Egypt

The current study focuses on the investigation of a collection of copper alloy and iron nails discovered amid numerous metal artifacts in the archaeological excavations of Tel Abu Seify, North Sinai, Egypt. This site, identified as a shipbuilding and repair facility, dates back to the Greco-Roman era (Circa 332BCE–A.D. 641). Different analytical methods were employed to ascertain the composition of the alloys, manufacturing techniques, and characteristics of the corrosion products in the nails. A range of techniques were utilized to achieve this goal, including optical and metallographic microscopy, X-ray radiography, portable X-ray fluorescence, SEM-EDS, micro-Raman spectroscopy, and X-ray diffraction. The results indicated that 19 of the examined nails were composed of copper alloy, except for two nails made of iron. The analysis revealed that the tin bronze nails were predominantly composed of copper, with a minor presence of tin (4.3 wt%), lead (4.7 wt%), and traces of iron and arsenic. Additionally, the iron nails were made of low-carbon iron alloys. Microscopic examination indicated that the nails were manufactured via cold hammering. The patina observed on the copper nails encompassed cuprite, atacamite, clinoatacamite, antlerite, and cerussite, often interspersed with the soil residues. The rust surfaces of the iron nails comprised hematite, magnetite, goethite, akaganeite, and lepidocrocite. The iron nails and some copper nails exhibited partial or total mineralization, whereas most copper nails remained in good condition, generally retaining their metallic cores.

Predicting the Invasion Range of the Common Myna, Acridotheres tristis Linnaeus, 1766 in Egypt under Climate Change

The common myna bird (Acridotheres tristis Linnaeus, 1766) is widely recognized as one of the most formidable invasive avian species globally. The bird poses significant challenges due to its ability to outcompete a variety of native cavity-nesting birds. Additionally, the common myna is a notable agricultural pest and a substantial threat to indigenous biodiversity. The current study is focused on understanding the distribution pattern of the common myna (Acridotheres tristis Linnaeus, 1766) in Egypt and the significant favorable conditions to predict the invasion scale of the bird to the Egyptian fauna. To determine the environmental variables influencing the invasion range of the common myna in Egypt, a Species Distribution Model (SDM) was employed. The current work documented 117 invasion sites of the species from February to December 2023. The predicted habitats are mainly concentrated close to the Nile Delta of Egypt, the Suez Canal region, North and South Sinai, in addition to scattered areas on the Red Sea coast, along the riverbanks of Upper Egypt, in addition to a few northwestern areas of the Western Desert. The most significant environmental factors affecting the establishment were the Minimum Temperature of the Coldest Month, the Mean Temperature of the Coldest Quarter, and Elevation. The current invaded areas comprise about 0.8% of Egypt (8240 km2 out of roughly one million km2). We found that this is significant and of concern due to the expectation of increasingly favourable conditions due to global warming; this will turn this invasive species into a real threat to Egyptian ecosystems due to its aggressive competition with native cavity-nesting birds, its impact as an agricultural pest, and its potential to disrupt local biodiversity.

Virulent-MDR-ESBL E. coli and Klebsiella pneumoniae report from North Sinai calves diarrhea and in vitro antimicrobial by Moringa oleifera

The health of calves has a significant impact on the production of cows and livestock. Some desert plants have pharmacological importance, as they can be used to reduce antibiotic resistance. Our hypothesis is designed to detect Virulent- Multidrug-Resistant and Extended- spectrum Beta- lactamase Enterobacteriaceae (Virulent-MDR-ESBL Enterobacteriaceae and to determine whether Moringa oleifera has antibacterial activity against the detected isolates. A total of 39 Enterobacteriaceae isolates from 28 diarrheic samples were collected from calves aged between 20 days and 20 months from 3 different flocks in North Sinai, Sahl-Eltina region, Egypt. E.coli 46% (18/39), O157 13% (5/39), Klebsiella pneumoniae 41% (16/39). MDR members accounted for 87%, while ESBL isolates accounted for 43%. The antibacterial activity is represented by microdilution. Minimum inhibition concentration (MIC) for the methanol extract of Moringa oleifera ranged from 2.5,5,10, and 25mg/ ml among E.coli isolates, and O157 was susceptible to (2.5mg/ ml), Klebsiella pneumoniae isolates were susceptible to (5-50mg/ ml). Analysis of the methanol extract revealed that ferulic acid was the dominant phenolic compound with a concentration of 29,832 parts per million (ppm). In silico docking study expected the active site of ferulic acid to act on the tyrosine bacterial enzyme through Pi-alkyl, Pi-anion, Carbon hydrogen bonds, and extra ionic attractive interactions with copper ions which can stabilize ferulic acid inside the targeted pocket Diverse virulent gene profiles were observed in E. coli. The Shiga toxin-producing Escherichia coli (STEC) was reported in 83% of the isolated E. coli, while the DNA gyrase (gyrA) was harbored in 100% of Klebsiella pneumoniae isolates. Various profiles of antibiotic resistance genes for both E. coli and Klebsiella pneumoniae isolates were distinguished. blaTEM genes were detected in 99% of E. coli and 100% of Klebsiella pneumoniae. Sequence analysis for E. coli strain DRC-North Sinai-Eg was placed in accession numbers (OP955786) for the Shiga toxin 2 gene (Stx2A), (OP997748) and (OP997749) for the Adhesion to host cell gene (Eae). For the hemolysine gene (hylA), the accession number was (OP946183). Klebsiellapneumoniae strain DRC-North Sinai-Eg was placed in (OP946180) for (gyrA). This study has proven the broad range of Moringa oliefera's antibacterial effects in vitro against the virulent-MDR- ESBL E. coli and Klebsiella pneumoniae isolated from North Sinai calves diarrhea. These are congruent with the disability effect on bacterial tyrosinase enzyme through docking study therefore, we recommend the usage of this desert plant as a prospective feed additive, we endorse this as an antibacterial new insight natural source and for the medication of considered pathogens with zoonotic impacts.Graphical

Effect of Student Perception on Teaching and Learning Mathematics in Secondary Schools in El’arish in North Sinai Governorate in Egypt

Purpose: The aim of this paper was to investigate the effect of students ‘perception on teaching and learning Mathematics students in public Schools in El’arish in North Sinai Governorate in Egypt. The hypothesis of the study was formulated and tested to guide the study.
 Methodology: The survey research design type was adopted and the targeted population of one hundred and ninety-nine (119) respondents composed by 5 principals, 16 mathematic teachers and 98 students from senior secondary schools, were sampled by using stratified sampling and sample random sampling techniques. The collected data was analyzed using descriptive statistics, correlation, and regression analysis through the statistical package for social science (SPSS) version 21. The data collected were analysed using descriptive statistics and multiple regression.
 Findings: The results of the findings indicated that the students’ perception was more correlated with teaching and learning Mathematics (r = 0.822; p= 0.000). Multiple linear regression analysis showed that students ‘perception contributed to 70.2% of variation on the performance, hence plays a vital role in teaching and learning Mathematics students in secondary schools in El Arish in North Sinai Governorate in Egypt. Additionally, the relationship between perception and students Mathematics performance in the study was very strong.
 Unique Contribution to Theory, Practice and Policy: The study recommended that Mathematics teacher should be diverse in their use of methodology which can as well help their student in their own area of learning mathematics.
