In search for a test measuring positive emotions in pigs for application in on-farm welfare auditing, three small experiments were conducted to examine the sensitivity of a novel object test designed to measure the pigs’ (residual) need/motivation for enrichment. In the experiments the interactions with a novel piece of rope were measured at pen level using a so-called AMI sensor (AMI: animal–m...
Burns due to explosions of various types of inflammable dust have been reported, including coal dust, flour and grain dust. A 33-year-old worker was burned over 33 per cent of his body surface area in a sawdust explosion. Recovery was uneventful. This is the first reported case due to this mechanism as far as we have been able to ascertain.
Aerosols in the atmosphere affect our health and quality of life. The most commonly measured property is their mass concentration. In this work was concentration aerosols by optical particle sizer range from 0.3 μm to 10 μm. It realized laboratory with an automatic heat source for pellet combustion. were firstly before combustion process, then during three types samples: pellets pure sawdust, 5...
sawdust is now being investigated as an adsorbent to remove contaminants from aqueous solution. heavy metals can be decreased very effectively with the organic material. in this research, adsorption of pb (ii) onto modified beech sawdust in a batch system was investigated. sawdust was collected from timber mill of qom, iran, and modified with h2so4 and naoh. then, the effects of various paramet...
OBJECTIVE The objectives of the study were to assess the effect of cacao bean husk as bedding material in free-stall barn on the behavior, productivity, and udder health of dairy cattle, and on the ammonia concentrations in the barn. METHODS Four different stall surfaces (no bedding, cacao bean husk, sawdust, and chopped wheat straw) were each continuously tested for a period of 1 week to det...
This paper reviews the sources, bioavailability and fate of heavy metals and organic contaminants in compost manure and in soils of which the manure is applied. The toxicity of heavy metals and organic compounds in soil of which would have come from applied compost is also discussed. Type of materials, their background and where collected for use in composting contribute to the sources of heavy...
Increasing eco-consciousness among consumers is creating an expanding niche market for textiles coloured using natural dyes. Natural dyes are derived from different parts of plants, animals (insects and invertebrates) minerals. Although plant sources common, a growing global population makes them compete with food crops. Hence, there need to investigate alternate avenues procuring This research...
Sawdust is one of the beneficial by-products wood production, along with a number others. In construction structures, sawdust, considered waste material, successfully used to create sawdust concrete. present study, new analysis mechanical and physical properties sawdust-reinforced epoxy resin composites (SRER) was presented. This mixing composite fabricated using compression molding techniques ...
