In and around the 13th century, two eastern authors describe the island of Sicily from different perspectives but with the common purpose of linking it to the Arab and Islamic world it had belonged to. Both describe the place with varied images which combine the real physical aspects with fantasy, and which show natural landscapes, both urban and rural, dominated by the presence of the great volcano. The study of this island using its landscapes as a key allows us to investigate the ideological processes of the authors who describe it. Al-Qazwīnī and Al-Harawī undertake a literary itinerary in which the images of idealization and Islamization or sanctification of the island are crystallised.

Abstract

This study describes the creation of a low-cost silica material using a silicate extract as a precursor. This precursor is made from inexpensive palm frond waste ash through a simple calcination process at 500°C and a green extraction with water. Nitrogen adsorption-desorption, FTIR analyses, and transmission electron microscopy were used to characterize the samples. The surface area of the obtained mesoporous silica ash material was 282 m2/g1, and the pore size was 5.7 nm. For the adsorption of copper ions, an excellent adsorbent was obtained. The maximum copper ion adsorption capacity of this inexpensive silica ash-based adsorbent for removing heavy metal ions Cu(II) from aqueous solutions was 20 mg/g, and the effect of pH, temperature, and time on its adsorption capacity were also investigated. In addition, the adsorption isotherms were fi tted using Langmuir and Freundlich models, and the adsorption kinetics were evaluated using pseudo-fi rst-order and pseudo-secondorder models. The results demonstrated that the synthesized adsorbent could effectively remove heavy metal ions from aqueous solutions at pH levels ranging from 2 to 5. The adsorption isotherms followed the Langmuir model, and the kinetic data fi t the pseudo-second-order mode well. The thermodynamic results Negative values of G° indicate that the adsorption process was spontaneous, and negative values of entropy S° indicate that the state of the adsorbate at the solid/solution interface became less random during the adsorption process. According to the findings, prepared silica from palm waste ash has a high potential for removing heavy contaminating metal ions Cu (II) from aqueous solutions as a low-cost alternative to commercial adsorbents.

Abstract

This paper presents a study of control strategies for 5-phase permanent magnet synchronous motors (PMSMs) supplied by a five-leg voltage source inverter. Based on the vectorial decomposition of the multi-phase machine, fictitious machines, magnetically decoupled, allow a more adequate control. In this paper, our study focuses on the vector control of a multi-phase machine using a linear proportional-integral-derivative (PID) current regulator in the cases of sinusoidal and trapezoidal back-electromotive force (EMF) waveforms. In order to determine currents’ references, two strategies are adopted. First one aims to minimize copper losses under constant torque, while the second one targets to increase torque for a given copper losses. These techniques are tested under a variable speed control strategy based on a proportional-integral (PI) regulator and experimentally validated.

Abstract

This study employed two primary approaches to determine the optimum structure: the lightweight and sustainable models. The lightweight model considered various factors such as materials, geometry, and dimensions of the brake disc rotor and brake pads. On the other hand, the sustainable model considers the manufacturing process and aims to reduce the carbon footprint. To calculate the optimal lightweight structure, finite element analysis was conducted using two different materials to compare the resulting stresses and determine the most appropriate material. Subsequently, four different models were utilized in finite element analysis to evaluate the displacement and stress and establish the optimum structure. Regarding sustainability, two distinct processes were employed to assess the environmental impact and energy consumption to adopt an eco-friendly approach. This paper investigates the transition from the initial brake disc rotor to a lightweight model, employing finite element analysis, topology optimization, and sustainability considerations. The work is achieved by comparing the cost between conventional and 3D printing processes.

Abstract

This paper presents the groundwater modelling of Beni Abbes palm grove in Southwest Algeria. Beni Abbes oasis alluvial aquifer is part of the Saoura Valley aquifer system, including a loose slick contained in a Quaternary alluvial em-bankment that fills the Beni Abbes basin. To address local needs, industry and agriculture, groundwater has been intensively exploited in recent years. Groundwater of the Beni Abbes oasis in the Saoura Valley oasis chain, is composed of a com-plex system, whose layer of alluvial terraces ensures a vital role for a 40-hectare palm grove. Due to its architectural position in the local aquifer system, the alluvial aquifer is mainly fed by the Great Western Erg and sometimes by the Saoura River floods. Based on the hydrogeological, hydrochemical characterisation and hydrodynamic modelling of the alluvial aquifer system of the Beni Abbes oasis, the mathematical model of finite difference and finite difference at steady state leads to the estimation of the hydrodynamic parameters of the aquifer and the evaluation of the complete water balance. The main results of this study provide a better understanding of the geometry and functioning of this aquifer currently in a state of concern. Furthermore, it is necessary to undertake integrated water resource management in this oasis in order to ensure sustainable development.

Abstract

Challenging job demands are those which require the use of high energy and thus may impair health but bring positive consequences too. The present study aimed to construct a measure for challenging job demands for university teachers.
Methods: The study is based upon the model developed by Makhdoom and Malik (2018) which proposed three challenging job demands including Regulatory Load, Social Load, and Cognitive Demands. On the basis of the literature review, Time Pressure was also studied as a factor. First of all, the authors created an initial item pool of 19 items which were categorized into four factors. The finalized item pool was administered on two independent samples drawn from various universities of Pakistan. In the first stage, the university teachers (N = 201) from three universities of the Punjab province were approached. EFA concluded three-factor and 13 items, which were then administered upon a sample of university teachers (N = 600).
Results: The CFA confirmed the three-factor structure of challenging job demands including Time Pressure, Cognitive Demands and Social Load. All the fit indices were within an acceptable range. The values of factor loadings and Cronbach Alpha justified the internal consistency and psychometric soundness of the newly developed measure.
Discussion: The study concludes a psychometrically sound scale to measure challenging job demands in university teachers which will be helpful in future studies. The limitations of the study along with suggestions for future research and important theoretical and practical implications are discussed.

Abstract

Umbilical hernia is one of the most common problems in young calves. This problem occurs in dairy sector as well as in the local farmers. Present study was conducted to compare outcomes of four different techniques of herniorrhaphy. Twenty four young calves (n=24) were divided in 4 groups (A, B, C, and D) which underwent four different surgical techniques. Group A underwent vicryl plus suture material and pants-over-west technique, Group B underwent mesh application with Dexon suture material by using simple interrupted suture pattern, Group C underwent closed method with Nylon No. 3 suture material by using vertical mattress suture pattern and Group D underwent clamp application method with Silk No. 2 suture material by using simple interrupted suture pattern. The result showed that mesh application method was comparatively better with respect to feed intake, body weight gain and healing time. There was no reoccurrence with non-significant hematological changes (p≤0.05). It is concluded that mesh application method is safer than other three techniques and there are no systemic effects of this surgical intervention on calves’ health.

Abstract

The present paper exposes how Morocco’s population and economic expansion pose a challenge to its capacity to supply energy demand, especially given how the scarcity of fossil fuels and their high market price now and in the future develop and follow strategies to achieve the objectives of sustainable development. The effectiveness of this investment and the vast number of unexploited resources have led Morocco to aim for a new ambition of obtaining 52% of its energy demands from renewable sources, making it one of the world’s leaders with regard to renewable energies. This paper analyzes the large specter of renewable energy sources and their potential in Morocco, including solar, hydroelectric, tidal, wave, and geothermal energy sources, then identifies the barriers halting its growth, going from storing and transmitting to financing, followed by the comparative costs and benefits approach.
It also assesses the country’s strategy for sustainable development, highlighting its financing, and then expands the scope of the research to explore other potential applications of renewable energy in the Kingdom, such as desalination and transportation, followed by providing a list of guidelines and recommendations on how the country can bypass the obstacles stopping it from harnessing and using these precious resources, The feasibility of these solutions were judged through a survey by the population which showed a very promising result.

Abstract

Potato (Solanum tuberosum L.), an important food crop in the world, is susceptible to many fungal pathogens including Alternaria solani and Fusarium oxysporum causing Fusarium wilt and early blight diseases. Mycoparasitic fungi like Trichoderma encode chitinases, cell wall degrading enzymes, with high antifungal activity against a wide range of phytopathogenic fungi. In this study, a binary vector harboring endochitinase gene of ~1,000 bp was constructed and used to transform potato nodes through Agrobacterium-mediated transformation. Out of several primary transformants, two transgenic potato lines were verified for transgene insertion and integration by Southern blot. In a pot experiment for Fusarium resistance, the transgenic potato lines didn’t show any symptoms of disease, instead they remained healthy post infection. The transgenic potato lines exhibited 1.5 fold higher mRNA expression of endochitinase at 7 days as compared to 0 day post fungus inoculation. It was evident that the mRNA expression decreased over days of inoculation but was still higher than at 0 day and remained stable upto 30 days post inoculation. Similarly, for A. solani infection assay, the mRNA expression of the endochitinase gene was 3 fold higher 7 days post inoculation compared to expression at 0 day. Although the expression decreased by1.2 fold during subsequent days post infection, it remained stable for 30 days, suggesting that protection in transgenic potato plants against fungal pathogens was achieved through an increase in endochitinase transcript.

Abstract

Orobanche crenata parasitism on lentil ( Lens culinaris Medik) is one of the most destructive factors for this crop in Morocco. Field and pot assays were performed to study the mitigation of O. crenata stress on two lentil genotypes, Bakria (partially resistant to O. crenata) and Zaaria (susceptible), using salicylic acid (SA) and indole acetic acid (IAA). These two hormones were applied separately at concentrations of 1 mM and 0.09 mM, respectively, using seed pre-treatment and/or foliar spray methods. SA and IAA seed pre-treatment for the susceptible genotype Zaaria and foliar spray for the resistant genotype Bakria gave the best control of O. crenata under field and controlled conditions. This control reached ~91% in Zaaria and 83% in Bakria and was sometimes accompanied by an increase in plant growth and seed yield compared to the untreated plants. Biochemical assays showed that SA and IAA reduced O. crenata infestation in lentil through induction of systemic acquired resistance characterized by increasing activities of phenol metabolizing enzymes (phenylalanine ammonia-lyase, peroxidase, and polyphenol oxidase) implicated in natural defense systems of plants. Treatment of plants with SA or IAA could be an alternative strategy of crop protection with more satisfactory preservation of the environment.

Abstract

The present work focuses on examining the batch removal of Fe (III) from water using powdered Peganum Harmala seeds, characterized as FT-IR. In this work, several parameters are measured, including contact time, pH, Fe (III) concentration, reaction temperature effect, and adsorbent dose effect. Fe (III) adsorption was assessed using a UV-vis spectrophotometer at a wavelength of 620 nm. The findings demonstrated a positive correlation between the dosage of adsorbent and Fe (III) ions removal, with an increase in the adsorbent dose corresponding to higher elimination of Fe (III) ions. Therefore, the Langmuir isotherm model yielded more accurate equilibrium data compared to the Frendulich model. The kinetic data were mostly analyzed using a pseudo-second-order model rather than a pseudo-first-order model. Thermodynamic parameters, including enthalpy (ΔH◦), entropy (ΔS◦), and free energy (ΔG◦), were calculated. The adsorption process was found to be exothermic. Overall, Peganum Harmala was a favorable adsorbent for removing Fe (III) from aqueous solutions.

Abstract

Thin films were prepared based on cellulose polymer doped with different ratios of natural dye derived from Portulaca grandiflora concentrations. The polymer and natural dye were extracted from eco-friendly materials—the cell walls of millet husks and Portulaca grandiflora, respectively. The spray pyrolysis technique was applied to prepare thin film samples to control the film morphology and reduce the roughness of the surface. Optical microscope and Fourier transform infrared were used to analyse structural, morphological, and functional groups for all samples, respectively. The peak absorbance, extinction coefficient, optical bandgap, Urbach energy, and optical conductivity for the thin films were determined using ultraviolet-visible spectroscopy. The results show an enhancement in the optical characteristics when the natural cellulose is doped with a dye. Doping cellulose with 5% P. grandiflora has led to a considerable reduction in the energy bandgap (to 1.95 eV), compared to the sample doped with 1%.

Abstract

The goal of the research was to evaluate the heavy metal detection and potential ecological risks in lake’s water. Geological formations consisting essentially of sandstone and quaternary marine or dune sands characterize the study area. With a climate of the Mediterranean type winters are mild and humid, whereas summers hot and dry. At the analysis center of the Faculty of Sciences, the monitoring of ETMs is carried out by ICP-MS, the processing of data and the validation of the analysis method have been drafted according to the NF T 90-120 standard applicable to the analysis in a laboratory. The analysis covers concentrations of heavy metals, which include Cu, Zn, Mn, Fe, Pb and As, in the water. Pollution load index ( PLI) values were above one (>1) which indicates progressive deterioration of the water quality. However, contamination factor ( CF) values of Pb and Cu, ranging from 8.31 to 15.68 and from 5.5 to 28.05 respectively, show that the studied water remains under a strong impact by Pb and Cu. Considering the severity of the ecological risk ( Er) for a single metal, the descending order of contaminants is Cu > Pb > Mn > Fe > Zn. In relation to the total ecological risk index ( RI), water from the lake shows low to considerable ecological risk.

Abstract

In order to determine the nature of the high salinisation rate of the waters of Lake Sidi Boughaba, which has been listed in the Ramsar list since 1980, 23 samples that were taken during four sampling operations were subjected to physicochemical analyses. The obtained results were processed using a combination of bi-varied methods (correlation tests) and multivariate statistical methods (principal component analysis – PCA). The physicochemical analyses reveal that they are alkaline waters with a pH ranging between 8.38 and 9.03, an electrical conductivity ( EC) of the order of 12.4 to 17.4 mS∙cm ^–1, and high levels of Na ⁺ and Cl ^–, up to 3700 and 6630 mg∙dm ^–3 respectively, indicating a marine origin of these waters. In addition, the statistical treatment revealed that the mineralisation of the waters of this ecosystem is controlled by four main mechanisms of the salinisation; the main mechanism underlying this strong mineralisation is due to the impact of the marine spray. The second-order processes are about the phenomenon of the ion exchange, the dissolution/precipitation of evaporitic and carbonate formations, the oxidation–reduction processes, notably the reduction of sulphates as well as biochemical phenomena due to the selective absorption of certain ions by fauna and flora.

Abstract

Lasiodiplodia theobromae and Pseudofusicoccum kimberleyense are pathogens causing trunk canker in Carya illioniensis and there are still no reports of effective forms of control. However, biological control is a promising measure. The objective of this work was to isolate, identify and evaluate the action of Trichoderma spp. in the in vitro control of L. theobromae and P. kimberleyense and to identify the compounds produced by the antagonist. Trichoderma spp. was identified by molecular technique and morphologically characterized. The antagonistic action of T. asperellum isolates (obtained from the rhizospheric soil, and of an isolate obtained from a commercial formulation) was evaluated by pairing cultures and volatile metabolites on L. theobromae and P. kimberleyense. Optimization of the cultivation method of T. asperellum was carried out and the compounds produced by the antagonist were identified by gas chromatography. Isolates obtained from the soil were identified as T. asperellum and decreased mycelial growth of L. theobromae and P. kimberleyense in the crop pairing test (48.98% S6 x Qt), as well as by volatile metabolites (29.85% SM21 x TR4). The cultivation conditions that generated the filtrates with the greatest antifungal action used 20 g · l ^–1 of corn maceration water, yeast extract 7.5 g · l ^–1, pH 5, agitation 100 rpm, sucrose 50 g · l ^–1, inoculum concentration 105 spores /ml. Among the identified compounds, some stood out for having bioactive action, such as pyran derivatives, celidoniol, deoxy, pentadecanoicacid, 2,3-dihydro-3,5-dihydroxy-6-methyl, propanoicacid, 1-methylethyl ester and 9-octadecenoic acid. The T. asperellum isolates showed potential for biocontrol in vitro, acting by different mechanisms.
