The Mediterranean region, characterized by its unique climatic and ecological conditions, is experiencing significant impacts from climate change. Rising temperatures and altered precipitation patterns are exacerbating environmental stresses, this exploratory study aimed to investigate the potential of machine learning to improve the accuracy of temperature forecasts for Tangier, Morocco, using a comprehensive meteorological dataset from Visual Crossing, we assessed the performance of seven regression models: Decision Tree, Extra Trees, Random Forest, AdaBoost, Gradient Boosting, XGBoost, and LightGBM over a 13-year period from January 1st, 2010 to December 31st, 2022. The models were trained and validated on separate time periods after rigorous data preprocessing, which addressed missing values, outliers, extracted temporal features, and normalization. The results indicated that the Random Forest MSE = 0.0404, XGBoost MSE = 0.2515, and LightGBM MSE = 0.3708 models achieved superior accuracy, demonstrated by favourable Mean Squared Error (MSE), Mean Absolute Error (MAE) (MAE = 0.0377, MAE = 0.1484, MAE = 0.2276) respectively, and R² scores (R² = 0.9987, R² = 0.9918, R²= 0.9879). This study demonstrates that machine learning models, particularly tree-based regressors, improve temperature forecasting accuracy by capturing complex, nonlinear patterns in historical weather data. It highlights how sophisticated algorithms, such as ensemble methods and deep learning architectures, are increasingly capable of capturing complex atmospheric patterns and improving predictive performance. Additionally, it emphasizes the critical importance of meticulous data preprocessing, an essential step that involves cleaning, normalizing, and augmenting meteorological data.  

The term \"cellulitis\" is frequently used to describe a non-necrotizing inflammation of the skin and subcutaneous tissues that is typically caused by an acute infection and does not affect the muscles or fascia. Warmth, erythema, tenderness, swelling, and localized pain are the hallmarks of cellulitis. Life-threatening and debilitating outcomes from cellulitis include necrotizing fasciitis, necrotizing hypodermitis, abscess formation, septic shock, and, in extreme cases, death. The current study aimed to assess public awareness of cellulitis in the Al-Qunfudhah region, Saudi Arabia. A descriptive cross-sectional study was conducted targeting all residents in Al-Qunfudhah, Saudi Arabia, during the period from January to March 2024. Data were collected using a pre-structured online questionnaire. The study questionnaire included participants' demographic data, cellulitis data, and knowledge and attitude towards cellulitis. The final questionnaire was uploaded online using social media platforms by the researchers and their friends until no more new participants were included. A total of 470 records were analyzed. Among the respondents, the majority were male (n=347, 73.8%), and the highest proportion fell within the age range of 18 to 25 years (n=174, 37.0%). The highest proportion of respondents correctly identified cellulitis as a medical condition affecting the skin and soft tissues underneath it, typically caused by infection or injury (n=278, 59.1%). Additionally, the majority acknowledged that cellulitis can cause pain, swelling, and redness in the affected area (n=240, 51.1%). As for factors associated with awareness of cellulitis, significant associations were found with age group (p=0.031), educational levels (p=0.003), and employment status (p=0.002). This study revealed a high level of awareness of cellulitis among participants, especially highly educated and employed participants. Participants believed that healthcare providers play a crucial role in raising population awareness of cellulitis health problems.

Purpose This study is part of the valorization of local materials and the reuse of industrial waste in construction. This study aims to improve the physical-mechanical properties of sand concrete. This work is a continuation of previous studies conducted on sand concrete, the purpose of which is to introduce industrial waste into this material. For this purpose, a glass waste in powder form is added. Design/methodology/approach This study is focused on the effect of adding glass powder (GP) whose mass percentage varies from 0 to 40% with an interval of 10% to target the right composition that ensures the best compromise between the characteristics studied. Findings The results found show that the workability and density of the studied concretes decreased with increasing GP dosage. Indeed, the optimal addition which constitutes the best compromise between the studied properties is 10% of GP. Improvements of up to about 9% in the case of flexural strength and about 18% in the case of compressive strength. The thermal conductivity has been reduced by 12.74%, the thermal diffusivity which characterizes the notion of thermal inertia has been reduced by about 4% and the specific heat mass has been reduced by 7.80%. Also, the shrinkage has been reduced by about 20%. The microstructure of the studied composite shows a good homogeneity between the aggregates. Finally, the addition of GP to sand concrete gives very encouraging results. Originality/value The interest of this study is in two parts. The first one is the exploitation of local materials: dune sand, river sand and limestone filler to meet the growing demand for construction materials. And the second one is the reuse of glass waste, in the form of powder (GP), to solve the environmental problem. All this participates in the improvement of the physical-mechanical properties of sand concrete and the extent of its response to the development of an economical structural concrete.

This paper investigates the immobilization of chromium in the industrial sludge-based geopolymer. Mechanical, physical and microstructure properties were used to characterize different samples. The results show that lower heavy metals addition has less effect on the compressive strength. However, excessive addition of Cr(VI) (1.5 and 3%) causes a deterioration of geopolymer matrix with a significant drop of the compressive strength. The compressive strength shows that the use of sodium hydroxide as an alkaline activator is not suitable for chromium immobilization. The use of 1.5 and 3% amount of chromium increases the conductivity of leachates, which explains a change in the microstructure of materials. This is in agreement with the results of compressive strength. XRD patterns of all samples show an amorphous structure with less effect of chromium on the crystalline phases. SEM of the reference sample demonstrates a dense structure of binder. However, the porosity of the matrix increases with the addition of 3% Cr(VI).

The achievement of the Sustainable Development Goals (SDGs) for any nation has become more of an urgent priority in the global agenda than at any time before, especially under the light of recent disrupting events such as the COVID-19 pandemic, the alarming food–water–energy trilemma, and the geopolitical upheavals impacting the supply chain of vital commodities. Assessing the sustainable progress of a country over time can help policy makers establish and develop robust strategies by identifying their strengths and weaknesses, allocating adequate resources, and understanding how far the country is from achieving the SDGs. No prior research has evaluated the SDGs performance composite index in Morocco. Hence, this study evaluates the national level of SDG progress by analyzing 13 out of 17 SDGs, including 46 available economic, social, and environmental indicators from 2001 to 2018, to provide factual data that can be used as a decision-making basis. The selection of indicators is established based on the framework adopted by the UN General Assembly. A composite index was created and quantified using the min–max normalization technique, the geometric product aggregation, and the overall scores of Morocco’s SDG performance and the different dimensions were calculated. The results show that economic performance was the worst among the other dimensions. Morocco is progressing to achieve the environmental and social targets, but more effort is required to absorb the needs linked with population growth and improvement of living standards. The developed framework could be of great interest for scientists and researchers to assess the national SDG progress of other countries.

The purpose of this research study is to produce a geopolymer mortar with a lower environmental impact, to recycle polyethylene terephthalate (PET) plastic waste, and study the possibility of using PET particles as a substitute for sand by replacing and using calcined industrial sludge as a precursor in mortar production. A study of the geopolymer mortars revealed a chemical and mineralogical composition and mechanically compatible with that of a control geopolymer mortar, defined as a mortar with no plastic added to the geopolymer paste. The industrial sludge precursors revealed the presence of (Quartz and Muscovite) two crystalline phases. The FTIR spectra of the geopolymer slurries showed the presence of Si-O-T, with this absorption band shifting to lower frequencies when PET particles were added to the slurry. We also analyzed SEM images of some samples. The compressive strength and flexural strength of the mortar showed a decrease with an increase in PET particles as an alternative to sand. Geopolymer mortars formulated with recycled plastic as a sand alternative displayed mechanical performance approaching that of sand-based mortars. These findings collectively suggest the viability of utilizing plastic waste as a raw material for geopolymer mortar production.

Choline salicylate [Ch][Sal] an active pharmaceutical ingredient ionic liquid (API-IL) aqueous solutions in the presence of L -glycine that is a simple simulated biological media has been studied. The thermodynamic and transport properties including density, speed of sound, viscosity and electrical conductance have been studied under atmospheric pressure and a temperature range of (288.15 to 318.15) K. The key thermophysical properties, including apparent molar volume ( V φ ), apparent molar isentropic compressibility ( κ φ ), viscosity B -coefficient, ion association constant ( K a ), and limiting molar conductivity ( Λ 0 ) were derived from these data. The transfer properties ( Δ tr V φ 0 , Δ tr κ φ 0 , and ΔB tr ) demonstrate the dominance hydrophilic-hydrophilic interactions between the IL and L -glycine in the studied systems that increased with L -glycine concentration. The COSMO results revealed that differences in molecular size, stability, and hydration behavior of [Ch][Sal] and L -glycine, with [Ch][Sal] exhibiting stronger hydration due to its larger size and hydrogen bonding capacity. These findings provide insights into solute-solvent interactions and potential synergistic effects of [Ch][Sal] and L -glycine as a simple simulated biological media contributing to the optimization of pharmaceutical formulations and related activities.

We report the synthesis of two novel halogenated nitro-arylhimachalene derivatives: 2-bromo-3,5,5,9-tetramethyl-1-nitro-6,7,8,9-tetrahydro-5H-benzo[7]annulene (bromo-nitro-arylhimachalene) and 2-chloro-3,5,5,9-tetramethyl-1,4-dinitro-6,7,8,9-tetrahydro-5H-benzo[7]annulene (chloro-dinitro-arylhimachalene). These compounds were derived from arylhimachalene, an important sesquiterpene component of Atlas cedar essential oil, via a two-step halogenation and nitration process. Characterization was performed using 1H and 13C NMR spectrometry, complemented by X-ray structural analysis. Quantum chemical calculations employing density functional theory (DFT) with the Becke3-Lee-Yang-parr (B3LYP) functional and a 6-31++G(d,p) basis set were conducted. The optimized geometries of the synthesized compounds were consistent with X-ray structure data. Frontier molecular orbitals and molecular electrostatic potential (MEP) profiles were identified and discussed. DFT reactivity indices provided insights into the compounds’ behaviors. Moreover, Hirshfeld surface and 2D fingerprint analyses revealed significant intermolecular interactions within the crystal structures, predominantly H–H and H–O contacts. Molecular docking studies demonstrate strong binding affinities of the synthesized compounds to the active site of protein 7B2W, suggesting potential therapeutic applications against various isolated smooth muscles and neurotransmitters.
