Studying and modeling to improve the system of a point absorber buoy for converting sea wave energy to support aquaculture in Binh Thuan province
In a previous paper, sea wave energy in the Phan Thiet (Binh Thuan) sea was studied using the point absorber method [1]. In this paper, we study and modeling to improve wave energy harvesting efficiency to support aquaculture in this sea area. We collected parameters of the wave energy in Phan Thiet sea in 2018 and combined them with the floating body dynamics equation for a point absorber buoy, we studied and analyzed the absorber dynamics equation with the aim of maximizing absorbed power by providing a natural period that is close to the predominant wave periods of the sea site for the poin
Effects of Thymelaea hirsuta crude extracts on gastric emptying and intestinal transit in mice: underlying mechanism of action
Thymeleae hirsuta (T. hirsuta) have been traditionally used for various medicinal purposes, including the treatment of inflammation, hypertension, and digestive disorders. This study aims to investigate the effects of decocted (DE) and hydromethanol (HME) extracts from T. hirsuta aerial parts on gastric emptying and intestinal transit in mice, as well as elucidate the underlying mechanisms. Gastric emptying and intestinal transit were assessed in mice following oral administration of DE and HME at different doses (125 mg/Kg, 250 mg/Kg, 500 mg/Kg). Pharmacological substances were used to explor
First detection and prompt pinpointing of pectinolytic bacteria causing blackleg and soft rot of potato in East-Algeria
Potato (Solanum tuberosum L) is a staple food considered as key factor in food and nutritional security, especially in developing countries and it is the target of many phyto-bacteriosis. Pectinolytic bacteria, responsible for blackleg disease and soft rot, are among the most destructive bacterial diseases in this crop worldwide. The present study is a substantial contribution to the survey of occurrence of pectinolytic Soft Rot Enterobacteriaceae (SRE) in Algeria. Isolation and identification of local strains were performed on potato plants recovered from EL-Harrouch district (north-east Alge
Phytochemical studies and Antifungal activity of leaves of Myrtus communis L. from Algeria
A chemical investigation of the leaves of Myrtus communis afforded three flavonoids, namely myricetin, myricetin-3-O-α–rhamnoside and myricetin-3-O- β- glucoside. The structures of the isolated compounds were established by chromatographic behavior and by means of UV, NMR and MS spectral analysis, as well as comparison with literature values. Moreover, the antifungal activity test was carried out on chloroform extract and essential oil of the leaves of Myrtus communis, using the direct contact method against Fusarium oxysporum f. sp. Lycopersici (FOL). Only essential oil showed an activit
Antioxidant, antihemolytic, antiinflammatory and analgesic Activities of flowers methanol extract of Malva sylvestris L
Malva sylvestris widely used in traditional medicine, is a kind of mallow derived from Malvaceae species and is recognized in Algeria as khoubaiz. This work focuses on the phytochemical study and evaluation of antioxidant, antihemolytic, anti-inflammatory and analgesic activities of flowers methanolic extract of Malva sylvestris. The phytochemical analysis revealed that the extract is rich in polyphenols (74.26±18.70 µg EGA/g extract), and in tannins (18.98±1.33 µg EC/mg extract). The antioxidant activity was investigated by DPPH, ferrous iron chelation, reducing power and AAPH tests. Resu
Evaluation of the acetylcholinesterase inhibitory and antioxidant activities of leaves from lesser burdock
Classical pharmacopoeia is replete with compounds that show therapeutic potential, including the ability to inhibit enzymes associated with specific diseases. The aim of this study was to evaluate the in vitro neuroprotective effects of extracts derived from the leaves of Arctium minus subsp. atlanticum, commonly known as "lesser burdock", an indigenous plant found in Algeria. The extracts were obtained using ethyl acetate, water/methanol, and aqueous extraction methods, and their efficacy against Alzheimer's disease (AD) was assessed. Different extracts were prepared by maceration or decoctio
Studying the Influence of Water Availability on Morphological and Yield Characteristics of Brassica napus L. in a Semi-Arid Environment.
To determine the effectiveness of irrigation, we studied some morphological and yield characteristics of a variety of rapeseed (Brassica napus L.) in the semi-arid highland region, El-Hammadia Bordj Bou Arreridj. The results showed an acceptable fit for all endpoints monitored, including trunk diameter, plant height, leaf area, number of silics per plant, and number of grains per silic. Despite the scarcity of rainfall, this crop yielded 12 qx/ha, with ramifications exceeding 731 and an average of over 370 silics per plant, underlining the need to grow it in various regions.
GC/MS analysis and in vitro antioxidant activity of the essential oil of Thymus ciliatus from northeastern Algeria
The components of essential oils of samples of the aerial parts of Thymus ciliatus (Desf.) Benth., collected at northeastern Algeria in different harvest period, isolated by steam distillation (TC/OL 2015) and hydrodistillation (TC/HE 2016) were analyzed by Gas Chromatography (GC) / Gas Chromatography-Mass Spectrometry (GC-MS and assayed for their antioxidant activities. Although both samples showed similar overall chemical compositions, the principal components were Camphor (44.47-33.18 %), Camphene (7.33-12.22%), Eucalyptol (6.97-6.69%), 4-Terpinenol (3.52- 6.27%), α-Pinene (2.72 -5.84%), Î
Assessment Of Iron and Zinc Content In Sorghum Germplasm: Implications For Biofortification
Ensuring adequate levels of essential micronutrients like iron (Fe) and zinc (Zn), in staple crops is crucial for addressing widespread micronutrient deficiencies and improving human health. The identification of germplasms with high grain Iron and Zinc concentrations represents a significant step forward in promoting crop biofortification efforts. Here in our study out of 86 germplasm 10 were found with high iron contents are IL 497, MR 47, IS 20575, AS 3883, ICSV 202, TNS 599, AS 3749, MIS 9652, MR 32B, SPV 615 and the 10 genotypes with low iron contents are IL 1136, MR 8, AS 2407, M-1061, I
Ground Beetles (Coleoptera) Communities Living in the Aleppo pine (Pinus halipensis) and Atlas cedar forests (Cedrus atlantica) of the Chrea National Park (Blida, Algeria)
In 2018, Carabids communities were investigated in an Aleppo pine area and Atlas cedar forests habitats of the Chrea National Park (Blida, Algeria), according to an altitudinal gradient of biodiversity. Carabids communities were collected monthly for one year using pitfall traps. In total, 208 individuals of ground beetles representing 18 species essentially carnivorous predators and valuable auxiliaries were captured. The harvested species belong to three groups and is divided between five families, whose Pterostichidae count nine species. The Aleppo pine site was the most diversified site wi
