The nanoparticle (NP) design space allows for variations in size, shape, composition, and chemical ordering. In the search low-energy structures, this results an extremely large which cannot be screened by brute force methods. work, we develop a genetic algorithm to predict stable bimetallic NPs of any metal composition. Our method predicts nanostructures agreement with experimental trends it captures detailed ordering 23,196-atom FePt NP nearly atom-by-atom accuracy. developed screening...

Abstract This study investigated the effectiveness of two plant growth-promoting rhizobacteria (PGPR) formulations, Bio Arc ® 6% WP (BA, Bacillus megaterium ) and BECTO Grow Roots (BGR; Serratia marcescens , Pseudomonas putida P. fluorescens ). Additionally, it focused on naturally infested soil that had undergone metam potassium fumigation to reduce root-knot nematode (RKN), specifically Meloidogyne incognita . It aimed monitor eggplant response biodiversity changes for 60 days experiment...

One of the challenges in mixing entomopathogenic nematodes (EPNs) with chemical control is low predictable compatible information; hence, pesticides are misused by farmers. Therefore, study aimed to clarify result abamectin and imidacloprid on infectivity EPNs against larvae hard-black beetle Pentodon bispinosus Kust., besides, investigating fluctuations joint action EPN species during period. Recommended dose (RD) (LT50= 5.20 14.20 d) was more efficient comparing 18.14 24.22 first third...

Field experiment was conducted to determine residues of pyridalyl insecticide on tomato leaves and fruits.Tomato plants were sprayed with the (Pleo 50% EC) at rate 100 ml/fad.on January, 2014.QuEChERS (catchers) method used for extraction clean-up samples.Residues determined 2 hours, 1, 2, 3, 5, 7, 10 14 days post-treatment using UHPLC-UV.The recovery percentages 89.29 96.73 % fruits, respectively.The results revealed that residue concentrations two hours after single application 1.007 0.815...

PARASITOLOGICAL survey of 98 slaughtered camels for ……gastrointestinal helminthes aged 1-5 and 6-10 years was carried out from the beginning March 2011 to end February 2012 at Toukh abattoir.The result showed that50 (51.02%) were infected with different helminth parasites.The only recorded trematode worm Schistosomabovis (2.04%).Small intestine harboured three types cestodes which Moniezia spp.(8.16%), Stieleziaglobipunctata (17.36%) Avitellinacentripunctata (1.02%).The collected nematodes...

The analysis revealed that the peak area percentages for diallyl sulfide, disulfide, and trisulfide were determined to be 5.67%, 87.99%, 6.34% respectively, based on standard allicin concentration. Upon comparing fresh gloved garlic samples with dried sheet samples, indicated of all components, namely allyl methyl disulphide, tetrasulfide, significantly elevated. Nevertheless, comparison glove a significant increase in % dimethyl trisulfide, propenyl disulfide compounds. results also showed...

Associated microorganisms significantly influence plant diseases regarding inhibition and acceleration of the infection process.The root-knot nematode (N), Meloidogyne incognita complex with root-rot fungal disease is an example a that requires collaboration multiple pathogens to induce epidemic [(Pythium debaryanum (P), Fusarium solani (F) Rhizoctonia (R)].The significant problem due various interwoven difficulties using conventional approaches control.Therefore, study intended introduce...

Abstract Background Cydnoseius negevi (Swirski and Amitai) (Acari: Phytoseiidae) is a promising bio-agent in the Mediterranean region. It attacks wide range of pest species. Two fundamental questions have been raised when C. was candidate for biological control applications hydroponic system. This study carried out to answer questions: (1) how long predatory female takes attack its prey non-choice application? (2) what do females prefer offered multiple choice (free-choice) preys?,...

Four different pest control agents (Beauveria bassiana (Balsam), orange oil, neem and pyriproxyfen) were evaluated at 0.5, 1 2 of field recommended concentrations (FRC) for their effectiveness on the biological aspects nd larval instar Chrysoperla carnea (Stephens) under laboratory conditions 26 ± 2°C 65 5% RH.Taking into consideration relative potency LC 25 50 levels, obtained results showed that oil was highest effective agent against C. carnea, recording value 10.61 µg / ml solvent, while...
