The aim of this study is the comprehensive planning for integrated management of solid waste at the industrial parks. The share of each industrial group including food, metal, chemical, non-metallic minerals, textile, electrical and electronical, and cellulose industries were 48.2, 14.9, 6.7, 22, 0.9, 0.6, and 6.5 percent, respectively. The results showed that nearly half of total industrial wa...
Moringa oleifera Lam., also known as the 'drumstick tree,' is recognized as a vibrant and affordable source of phytochemicals, having potential applications in medicines, functional food preparations, water purification, and biodiesel production. The multiple biological activities including antiproliferation, hepatoprotective, anti-inflammatory, antinociceptive, antiatherosclerotic, oxidative D...
in 2007, research was carried out to determine the type and amount of asbestos fibers in a croatian factory with a long history of making asbestos-containing products.since the 1970s, asbestos fibres have been considered carcinogenic in humans i.e as a known cancer-causing agent. in the environment, asbestos fibres are inactive and naturally resist biodegradation. in time, fibres can only be gr...
To understand and optimise downstream processing of ores, reliable information about mineral abundance, association, liberation textural characteristics is needed. Such can be obtained by using Optical Image Analysis (OIA) in reflected light, which achieve good discrimination for the majority minerals. However, automated segmentation non-opaque minerals, such as quartz, have reflectivity close ...
The prebiotic significance of laboratory experiments that study the interactions between oligomeric RNA and mineral species is difficult to know. Natural exemplars of specific minerals can differ widely depending on their provenance. While laboratory-generated samples of synthetic minerals can have controlled compositions, they are often viewed as "unnatural". Here, we show how trends in the in...
More than half of the >5000 approved mineral species are known from five or fewer localities and thus are rare. Mineralogical rarity arises from different circumstances, but all rare mineral species conform to one or more of four criteria: (1) P-T-X range: minerals that form only under highly restricted conditions in pressure-temperature-composition space; (2) Planetary constraints: minerals th...
The Food and Agriculture Organization statistics for 2001 (http://apps.fao.org/page/collections? subset agriculture) show that 274 million metric tons of grain legumes were produced across the world, of which 177 million were soybeans (Glycine max; one-half of which were produced in the U.S.) compared with 2 trillion metric tons of cereals. Legume seeds are put to a myriad of uses, both nutriti...
a study was conducted to evaluate the effect of feeding different levels of protein to black baladi breed kids. weanling baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. kids were divided randomly to one of the three treatments for 12 weeks. the three dietary treatments were: t1: control ration, formulated according to nrc to cover the protei...
this study investigated the relationship between clay minerals and different soil moisture regimes in gypsiferous soils of fars province in southern iran. the overall climate of the province is arid and semi-arid and, under this condition, parent material is the most important factor affecting clay minerals distribution. beside this factor, climate conditions have determining role too. palygors...
