An optimal sizing of an off-grid microgrid system composed photovoltaic (PV)/building integrated (BIPV)/battery energy storage installation is undergone for Net Zero Energy Residential Building blocks across six different climates Morocco in order to reach the objective providing all load requirements at minimum. The Particle Swarm Optimization algorithm used find system, by considering hourly spatiotemporal variations both solar availability and demand variation, with lowest Total...
The present work was designed to investigate the effects of different extraction processes, namely ultrasonic-assisted, supercritical fluid, microwave-assisted and Soxhlet applied carob pods. total phenolic quantification antioxidant activity were assessed by means rapid in vitro spectrophotometric assays; profile identified using ultra-high performance liquid chromatography coupled mass spectrometry. results revealed that compounds capacity varied significantly with nature process. content...
Wild jujube “Ziziphus lotus (L.) Desf.” belongs to the Rhamnaceae family and is a traditionally herbaceous medicinal plant. It very common in arid semi-arid regions currently used for its antidiabetic, sedative, analgesic, anti-inflammatory hypoglycemic activities. The aim of present work was characterize physico-chemical properties phytochemical profile wild sample collected from Guercif region, order determine polyphenolic compounds antioxidant ability Analyses were carried out directly...
The aim of this study was to determine the polyphenolic compounds and antioxidant ability Arbutus unedo fruits, collected from three regions northern Morocco, using high-performance liquid chromatography coupled diode array electrospray ionization mass spectrometry detection. proper extraction method has been selected achieve objective. After delipidation, harvests were extracted by sonication two solvents with increased polarity ethyl acetate MeOH:water, 80:20 (v/v). Total polyphenols,...
A method for the extraction of phenolic compounds from grape seeds and skins using microwave-assisted (MAE) was developed. Optimization effects parameters in terms results obtained response surface methodology. The studied were solvent (methanol, ethanol, acetone, water), percentage methanol water, quantity sample relation to volume (solid:liquid, 10–50 mg mL−1), power (100–500 W), magnetic stirring speed (0–100%), time (5–20 min). Finally, repeatability intermediate precision determined....
In the present work, adsorption behavior of Eriochrome Black T (EBT) on waste hemp activated carbon (WHAC) was examined. The surface WHAC modified by H3PO4 acid treatment. and structural characterization adsorbents carried out using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) analysis. effect influential parameters (pH, contact time, dosage, initial concentration) EBT onto examined in batch experiments; some such as pH, concentration dose were improved...
Within the framework of sustainable development and carbon-neutrality, building sector is a key target national energy strategy towards zero-carbon economy in Morocco. This article comes response to this need by assessing performance solar-powered low-embodied-carbon semi-arid climate Benguerir-Morocco, which refers fifth climatic zone thermal regulation for constructions Morocco (RTCM). To do so, we’ve used Openstudio as modeling tool investigate self-sufficiency detached Net Zero Energy...
The aim of this study was to characterize the phytochemical content as well antioxidant ability Moroccan species Chamaerops humilis L. Besides crude ethanolic extract, two extracts obtained by sonication using solvents with increased polarity, namely ethyl acetate (EtOAc) and methanol-water (MeOH-H2O) 80:20 (v/v), were investigated both spectroscopy chromatography methods. Between extracts, MeOH-H2O one showed highest total polyphenolic equal 32.7 ± 0.1 mg GAE/g DM respect EtOAc extract (3.6...
The relationship between agricultural activities, soil characteristics, and groundwater quality is critical, particularly in rural areas where directly supplies local people. In this paper, three sandy soils were sampled analyzed for physicochemical parameters such as pH, water content, bulk density, electrical conductivity (EC), organic matter (OM), cation exchange capacity (CEC), grain size distribution. Major trace elements by inductively coupled plasma-optical emission spectrometry...
In this work three chromatographic methods were developed to reduce the total time of analysis main compounds in Aloe vera extracts. The first method was a regular reverse phase system using particulate C-18 column. Methods already published used as starting point for development new method. All separated 32 minutes. second employing monolithic type Using 4.5 mL min −1 flow, reduced 6 minutes with very similar resolution values. third an ultraperformance liquid system, and final phenolic 4...
Phenol red (X-PR) and malachite green carbinol (MGC) are two textile finishing dyes, which present in aquatic environments through industrial effluents. Due to the toxic nature of both they harmful human health. In study, materials, barley seeds biochar (Hordeum vulgare L.), were used remove dyes an aqueous solution. The materials characterized by AFM, FTIR, SEM, XRD EDX techniques. this parameters studied adsorbent dose, pH, initial adsorbate concentration contact time. maximum equilibrium...
Abstract Activated carbon modified by phosphoric acid noted CAa was successfully used as a new low‐cost adsorbent for removing Cu 2+ , Ni and Cr 6+ metal ions from artificially contaminated aqueous solutions. Experiments were performed in batches adsorption kinetics isotherms. Scanning electron microscope (SEM) observations well nitrogen adsorption–desorption BET surface area measurement showed the formation of mesoporous with an average pore size 3.1 nm ABET = 678.74 m 2 g −1 . The data...
As climate change is globally widespread and intensifying, there an urgent call for buildings to undergo energy reduction decarbonization in order reach carbon-neutrality by 2050. This article comes response this need, comparing the thermal savings discomfort mitigation from implementing climate-responsive design strategies with respect hot semi-arid of Morocco. To do so, we've used EnergyPlus evaluate performance indoor comfort conditions two passive unoccupied homes: Home_1 home_2;...
