The present work demonstrates the development of hydroxyapatite (HA)/gold (Au) nanocomposites to increase adsorption methylene blue (MB) dye from wastewater. HA nanopowder was prepared via a wet chemical precipitation method by means Ca(OH)2 and H3PO4 as starting materials. biosynthesis gold nanoparticles (AuNPs) has been reported for first time using plant extract Acrocarpus fraxinifolius. Finally, as-prepared mixed with an optimized AuNPs solution produce HA/Au nanocomposite. nanocomposite...
Detecting sugar beetroot crops with mechanical damage using machine learning methods is necessary for fine-tuning beet harvester units. The Agrifac HEXX TRAXX an installed computer vision system was investigated. A video camera (24 fps) above the turbine, which receives dug-out beets after digger and connected to a single-board computer. At preprocessing stage, static insignificant image details were revealed. Canny edge detector excess green minus red (ExGR) method used. identified areas...
The self-assembly of lignin (molecular and supramolecular) is driven mainly by non-covalent interactions, the nature solvents antisolvents directly affect driving forces. particle usually formed noncovalently bonded cylindrical subunits. In this paper, we report a simple method which can be used to synthesize nanoparticles using spray freezing. based on two properties dimethyl sulfoxide (DMSO) that are excellent solubility high melting point. Based these properties, kraft solution in DMSO...
The paper presents nutritional problems of elderly people from an international perspective, due to the diversity recommendations. acceptance and readiness purchase functional foods by consumers has been widely studied, but no studies have conducted on attitude older innovative products with health consequences. perception food analysis factors determining that improves are great importance. first part study provides overview available market, against a background diverse needs people. In...
Topographic and edaphic gradients usually arrange ecotonal boundaries. Although the interrelationships between vegetation factors are relevant in most types of ecotones, they not adequately documented. The clearly defined forest-agriculture land ecotone at Proklest experimental site Training Forest Enterprise (T.F.E), Masaryk Křtiny, Czech Republic presents an opportunity to investigate these inter-relationships. Our aim was determine effects reflected by changes soil reaction other physical...
Wood-based cellulose nanofibrils (CNF) offer an excellent scaffold for drug-delivery formulation development. However, toxicity and haemocompatibility of the drug carrier is always important issue. In this study, toxicity-related issues CNF were addressed. Different doses orally administered to Drosophila different tests like developmental cycle, trypan blue exclusion assay, larva crawling thermal sensitivity cold larval light preference test, climbing behaviour, nitroblue tetrazolium (NBT)...
Starting from the influencing parameters of threshing and separation implicit seed losses that occur within this process, paper searched for identified optimal regimes to minimize depending on process parameters. The evacuation (pev) depend rotor speed (n) peripheral (vp), material feed (va), space between counter-rotor (δ), flow (Q), density (ρ), length apparatus (L). As ρ L are constant, variation in relation each arguments was followed: vp, Q, ρ, va, respectively, minimization by loss...
The objective of the present work was to determine effect pretreatment by extrusion on biogas and biomethane yield lignocellulosic substrates such as maize silage straw silage.The yields before after treatment were compared.Moreover, energy efficiency analyzed in order assess applicability process an agricultural plant.Extrusion tests carried out a short single-screw extruder KZM-2 which length-to-diameter ratio screw 6:1 rotational speed 200 rpm.The plant laboratory scale, using 15...
This paper presents the results of a study on influence addition digestate (DG) sludge from an agricultural biogas plant mechanical properties coating obtained thermoplastic starch (TPS). The dried, fragmented digestate, some which had previously undergone ultrasound treatment, is used in study. Biocomposites are produced by pouring method using Teflon moulds as matrices. physicomechanical included determination basic parameters materials obtained. Strength parameters, contact angle,...
Hundreds of bacteria, viruses, eukaryotes, and archaea comprise the human intestinal microbiota, which constitutes a complex ecology. Recent years have established significance gastrointestinal microbiome in study biological microorganisms. Diverse techniques for cultural extraction analysis make it difficult to cultivate gut bacteria species. To determine causative microorganism, is necessary investigate microbes bacteria. Novel efficacious remedies illnesses are required. Bioinformatics...
Operational research, i.e. searching for optimal solutions in a situation of uncertainty and risk, can also be used to support decisions purchase expensive agricultural machinery. Although Polish farmers receive subsidies from the EU, it does not mean they do need make well-thought-out purchases, because wrong will have long-term consequences while using The article presents results IFOP – system which has been available on Internet several years. It collects data farming machinery vehicles...
Kaplan–Meier analyses can be used in many disciplines, e.g., agricultural engineering. Agricultural machinery and vehicles regarded as objects that ‘die’ because, like living creatures, they failed, although after repair until scrapped. This article presents an example of using the estimator to plot reliability function curves five different models Zetor farm tractors. The research shows median operating time for one tested models, which is about 200 engine-operating hours, 20% lower than...
