current political and social transformations and their ramifications for
higher education and the social sciences in Egypt and the region. The
overarching objective of the project is to enter a productive dialogue on
theories, methodologies and topics in social science research among Arab and
German researchers. At the same time, we aim to improve teaching and research
structures in the social sciences in a sustainable and efficient way. This
will build studentsâ and teachersâ capacities on both shores of the
Mediterranean and at the same time strengthen institutional efforts to promote
the role of social sciences in the current transformations
Qualitative traits of various Egyptian clover varieties under efficiency of bio-chemical phosphorus fertilization and lithovit regimes
Received: August 3rd, 2022 ; Accepted: October 19th, 2022 ; Published: November 1st, 2022 ; Correspondence: [email protected] investigation was performed at the Agriculture Research Station, Faculty of Agric.
Zagazig Univ., Sharkia Governorate, Egypt, throughout the winter seasons of 2019/2020 and
2020/2021. The study aimed to evaluate the influence of ten bio-chemical fertilization and lithovit
regimes on forage quality of 1st and 3rd cuts of various Egyptian clover varieties (Berseem,
Trifolium alexandrinum L.) q.e. Helaly, Gemmeza 1, Sakha 4, Serw 1, Giza 6 and local variety.
The ten fertilization regimes were F1, control; F2, chemical phosphorus 15.5 P2O5 kg fad-1
;
F3, bio-phosphorus fertilizer âphosphoreinâ; F4, 50% of F2 + phosphorein; F5, 25% of F2 +
phosphorien; F6, F2 + lithovit; F7, F3 + lithovit; F8, F4 + lithovit; F9, F5 + lihtovit; F10, sole lithovit.
Giza 6 Egyptian berseem variety ranked first in forage quality because of its high content of each
CP (%), NFE (%), TDN (%), and DP (%) in the 3rd cut. The local berseem variety ranked the least
over the six Egyptian clover varieties with the highest ash (%) in the 1st cut. Other varieties were
in between. Allusion to the bio-chemical phosphorus fertilization and lithovit regimes, application
of any phosphorus fertilization regimes surpassed the control treatment in most nutritive values.
Application of F9 fertilization regime (25% chemical P + bio-fertilizer âphosphorienâ +
nano-fertilizer âlithovitâ) tended to produce high forage quality with high content of CP (%) in
the 1st cut, TDN (%) in both 1st and 3rd cuts as well as DP (%) in the 1st cut
Comparative Responses of Three Pomegranates (Punica Granatum L.) Varieties to Salinity
During 2011 and 2012 seasons, three pomegranate cultivars Manfalouty, Wonderfull and NabâElgamal. were subjected to saline ground water at concentration (1.8 and 6.0 dSm-1). The trees about seven years old grown at 2.5 x 3.5 m apart in sandy clay loam soil under Sohag environmental conditions. Results revealed that irrigation with saline water (6dSm-1), increased salt accumulation in leaves. On the other hand, the higher significant reduction was observed in growth; flowering and yield with highly fruit cracking in relative to 1.8 dSm-1. Total Sugar and acidity percentages did not alter significantly with varying Saline irrigation. The studied varieties were affected differently by salt-stress, Manfalouty, Wonderfull, and Nab-Elgamal in descending order in response to salinity
Bayesian Convolution for Stochastic Epidemic Model
Dengue Hemorrhagic Fever (DHF) is a tropical disease that always
attacks densely populated urban communities. Some factors, such as environment,
climate and mobility, have contributed to the spread of the disease. The Aedes
aegypti mosquito is an agent of dengue virus in humans, and by inhibiting its life
cycle it can reduce the spread of the dengue disease. Therefore, it is necessary to
involve the dynamics of mosquito's life cycle in a model in order to obtain a reli-
able risk map for intervention. The aim of this study is to develop a stochastic
convolution susceptible, infective, recovered-susceptible, infective (SIR-SI) mod-
el describing the dynamics of the relationship between humans and Aedes aegypti
mosquitoes. This model involves temporal trend and uncertainty factors for both
local and global heterogeneity. Bayesian approach was applied for the parameter
estimation of the model. It has an intrinsic recurrent logic for Bayesian analysis by
including prior distributions. We developed a numerical computation and carry
out simulations in WinBUGS, an open-source software package to perform Mar-
kov chain Monte Carlo (MCMC) method for Bayesian models, for the complex
systems of convolution SIR-SI model. We considered the monthly DHF data of
the 2016â2018 periods from 10 districts in Kendari-Indonesia for the application
as well as the validation of the developed model. The estimated parameters were
updated through to Bayesian MCMC. The parameter estimation process reached
convergence (or fulfilled the Markov chain properties) after 50000 burn-in and
10000 iterations. The deviance was obtained at 453.7, which is smaller compared
to those in previous models. The districts of Wua-Wua and Kadia were consistent
as high-risk areas of DHF. These two districts were considered to have a signifi-
cant contribution to the fluctuation of DHF cases
ComunitĂ cristiane nellâislam arabo. La sfida del futuro
Preesistenti all'islamizzazione del Medio Oriente, le comunitĂ cristiane costituiscono tuttora un importante elemento di pluralismo, sebbene oggi a rischio di sopravvivenza, nelle societĂ arabe a maggioranza musulmana.

SutteARIMA: A Novel Method for Forecasting the Infant Mortality Rate in Indonesia
This study focuses on the novel forecasting method (SutteARIMA) and its application in predicting Infant Mortality Rate data in Indonesia. It undertakes a comparison of the most popular and widely used four forecasting methods: ARIMA, Neural Networks Time Series (NNAR), Holt-Winters, and SutteARIMA. The data used were obtained from the website of the World Bank. The data consisted of the annual infant mortality rate (per 1000 live births) from 1991 to 2019. To determine a suitable and best method for predicting Infant Mortality rate, the forecasting results of these four methods were compared based on the mean absolute percentage error (MAPE) and mean squared error (MSE). The results of the study showed that the accuracy level of SutteARIMA method (MAPE: 0.83% and MSE: 0.046) in predicting Infant Mortality rate in Indonesia was smaller than the other three forecasting methods, specifically the ARIMA (0.2.2) with a MAPE of 1.21% and a MSE of 0.146; the NNAR with a MAPE of 7.95% and a MSE of 3.90; and the Holt-Winters with a MAPE of 1.03% and a MSE: of 0.083
Promising photocatalytic and antimicrobial activity of novel capsaicin coated cobalt ferrite nanocatalyst
Abstract In this study, CoFe2O4 nanoparticles were prepared by the co-precipitation method then surface modified with Capsaicin (Capsicum annuum ssp.). The virgin CoFe2O4 NPs and Capsaicin-coated CoFe2O4 NPs (CPCF NPs) were characterized by XRD, FTIR, SEM, and TEM. The antimicrobial potential and photocatalytic degradation efficiencies of the prepared samples via Fuchsine basic (FB) were investigated. The results revealed that CoFe2O4 NPs have spherical shapes and their diameter varied from 18.0 to 30.0 nm with an average particle size of 25.0 nm. Antimicrobial activity was tested on Gram-positive (S. aureusATCC 52923) and Gram-negative (E. coli ATCC 52922) by disk diffusion and broth dilution methods to determine the zone of inhibition (ZOI) and minimum inhibitory concentration (MIC), respectively. UV-assisted photocatalytic degradation of FB was examined. Various parameters affecting the photocatalytic efficiency such as pH, initial concentration of FB, and dose of nanocatalyst were studied. The in-vitro ZOI and MIC results verified that CPCF NPs were more active upon Gram-Positive S. aureus ATCC 52923 (23.0 mm ZOI and 0.625 Όg/ml MIC) than Gram-Negative E. coli ATCC 52922 (17.0 mm ZOI and 1.250 Όg/ml MIC). Results obtained from the photocatalytic activity indicated that the maximum FB removal achieving 94.6% in equilibrium was observed using 20.0 mg of CPCF NPS at pH 9.0. The synthesized CPCF NPs were effective in the removal of FB and also as potent antimicrobial agent against both Gram-positive and Gram-negative bacteria with potential medical and environmental applications
Enhanced photocatalytic and antibacterial activities of novel Ag-HA bioceramic nanocatalyst for waste-water treatment
Abstract Hydroxyapatite (HA), the most common bioceramic material, offers attractive properties as a catalyst support. Highly crystalline mono-dispersed silver doped hydroxyapatite (Ag-HA) nanorods of 60Â nm length was developed via hydrothermal processing. Silver dopant offered enhanced chemisorption for crystal violet (CV) contaminant. Silver was found to intensify negative charge on the catalyst surface; in this regard enhanced chemisorption of positively charged contaminants was accomplished. Silver dopant experienced decrease in the binding energy of valence electron for oxygen, calcium, and phosphorous using X-ray photoelectron spectroscopy XPS/ESCA; this finding could promote electronâhole generation and light absorption. Removal efficiency of Ag-HA nanocomposite for CV reached 88% after the synergistic effect with 1.0Â mM H2O2; silver dopant could initiate H2O2 cleavage and intensify the release of active ÈźH radicals. Whereas HA suffers from lack of microbial resistance; Ag-HA nanocomposite demonstrated high activity against Gram-positive (S. aureus) bacteria with zone of inhibition (ZOI) mm value of 18.0 mm, and high biofilm inhibition of 91.1%. Ag-HA nanocompsite experienced distinctive characerisitcs for utilization as green bioceramic photocatalyst for wastewater treatment
