Abstract In this study, we explored the green synthesis of metal nanoparticles (Ag-NPs, Au-NPs, and Pd-NPs) using Moringa oleifera seed (MOS) extract, which is known for its nutrient density, antioxidant properties, anti-inflammatory effects, potential benefits in managing cholesterol, blood sugar levels, as well promoting digestion, skin, hair health. The nanoparticles’ size was controlled by varying concentration MOS extract. successful formation Au-NPs Ag-NPs confirmed through surface...

Recently, algae have attracted the attention of investigators as a renewable source compounds that can contribute to nanoparticle creation. The use biomass facilitate preparation copper oxide nanoparticles (CuONPs), well their application, were aims present study. High performance liquid chromatography analysis algal indicated presence daidzein (2550 µg/mL), followed by ellagic acid (596 µg/mL). Algal extract was successful bio-reducing agent for CuONPs fabrication at different temperatures...

The article is devoted to the development of theoretical issues related modeling depth embedding a metal woven mesh and increasing linear size during restoration parts from copperbased alloys by electrocontact welding. Based on proposed grid shape coefficient, dependences have been obtained that make it possible calculate increment workpiece required wires into base metal. data calculations are confirmed results experimental studies.

Wood modification via silicon ingredients was investigated to increase its resistance biological decay. Surfactant and desiccant features of derived products silicates are considered the main contributors in wood The detected fungus from decayed sample identified as Phanerochaete chrysosporium. Inhibitory tests showed that sodium silicate (SS) more effective than potassium (PS) copper sulfate (CS) against P. chrysosporium growth. weight loss infected with without treatment 32.2%, while by...

Background: The fall armyworm, Spodoptera frugiperda , poses a significant threat to over 90 plant species, causing extensive damage by consuming fresh leaves, hindering growth, and ultimately reducing crop yields. Integrated pest management strategies emphasize eco-friendly approaches, minimizing harm non-target organisms. Among these, biological control methods, including the use of extracts specific microorganisms, have shown considerable efficacy in controlling armyworm. Methods: This...

Polyacrylonitrile co-polymer microfibers of diameter 12.5 μm was used for electrospinning to produce nanofibers and then as a stationary phase in UTLC on-plate identification separation amino acid from drug sample.

Background: In type 2 diabetic patients, resistant hypertension (RH) is associated with higher cardiovascular diseases (CVDs) and renal diseases; however, a prevalence of RH in the Middle East unknown. Long duration uncontrolled blood pressure diabetes may increase risk RH. This study aimed to assess among adult determine relationship between patient demographics. Methods: A cross-sectional was conducted from December 25, 2015 end January 2016 at National Center for Diabetes, Endocrinology,...

The bird cherry-oat aphid, Rhopalosiphum padi (Linnaeus) was studied at 15, 20 and 25oC constant temperatures. Wheat seedlings were offered for feeding maintaining the R. using Punctured Ependorf Tube Technique. showed longest life cycle duration 15oC as 12.77±1.71days. This decreased to 8.36±0.79 6.74±0.56 25oC, respectively. fecundity rate lowest (35.41 progenies/female) 25oC. It higher both 15 20oC 50.2 53.429 progenies/female, span recorded 49.47±16.43days. 34.05±6.22 19.47±4.16 days...

Bacillus thuringiensis strains that belong to B. thuringiensis, kurstaki and soil-isolated B.t. were assessed in the following phytopathogenic: Rhizoctonia solani, had their mycelial growth decreased after incubation presence of bacterial strains. The bacteria have also pathogenic effect against insect pest Spodoptera littoralis. isolate D-1 HD-203 found be inhibiting R. strain displayed highest percentage inhibition (64%) showed 49% inhibition. Antagonistic activity was maintained up pH...

The biological and biochemical effects chloropyrifos, camphor extract their combination were studied against the 4 th instars of Spodoptera littoralis under semi-field conditions.The results indicated that LC 50 for chloropyrifos was 0.08 ppm 13.3 x 10 3 extract.The estimated Co-toxicity factor 13.2 So, there is an additive effect between oil S. littoralis.Oil prolonged larval pupal duration also same happened when using mixture chloropyrifos.This prolongation accompanied with a reduction in...

The biological and histological effect of insect growth regulator (flufenoxuron) evaluated on 2nd larval instar Agrotis ipsilon as a chitin synthesis inhibitor. sublethal dose LC50 was used to investigate its some developmental reproductive parameters that survived treatment newly molted second instars. Results indicated the flufenoxuron significantly enhanced mean pupal durations, whereas they declined percentage pupation, adult emergence, longevity, fecundity, fertility compared untreated...

Aqueous ethylene glycol (ethane 1,2 diol) as a green mobile phase has been used for thin layer chromatographic (TLC) studies of cationic surfactants on alumina layers. Nineteen solvent systems were to examine the mobility and discover best TLC system selective separation dodecyl trimethylammonium bromide (DTAB) from multi-component mixture other surfactants. Among studied, M3 (ethylene glycol: water, 8:2) was achieving DTAB because in this all except insignificant. Effect organic additives...

Spirulina platensis has roles in biotechnological product advancement due to its safety for humans and animals. Analysis of S. extract by high-performance liquid chromatography reflected the presence 14 phenolic flavonoid compounds with different concentrations such as ellagic acid (333 µg/g), gallic (294 methyl gallate (147 naringenin (144 chlorogenic (142 µg/g).
