In grinding practice, heterogeneous poli-mineral systems are more common than homogeneous mono-mineral system. The heterogeneity of raw materials in mineral beneficiation circuit results by virtue the varying properties constituents an ore. Therefore, main objective this investigation is to study effect preheating on grindability quartz as a ore, and nepheline syenite one. 2n Factorial method w...

We conducted two trials to evaluate the effects of extruding vs dry-rolling either corn or grain sorghum on intake, digestibility, and performance of finishing steers. In Trial 1, 92 crossbred steers (average BW 413 kg) were used in a 2 x 2 factorial design. Diets contained either dry-rolled corn (RC), extruded corn (EC), dry-rolled grain sorghum (RGS), or extruded grain sorghum (EGS). Diets we...

Some Swedish spring wheat varieties have recently been shown to carry a rare wildtype (wt) allele of the gene NAM-B1, known to affect leaf senescence and nutrient retranslocation to the grain. The wt allele is believed to increase grain protein concentration and has attracted interest from breeders since it could contribute to higher grain quality and more nitrogen-efficient varieties. This stu...

Introduction: Returned extraterrestrial samples, planetary, asteroidal or cometary, are so valuable that initial assessment of the most appropriate analytical protocols for each grain is essential. It is particularly important to know the distribution and interrelationships of specific mineral components. Numerous sophisticated microanalysis techniques are now available [1], yet many may damage...

Introduction: During a nano-mineralogy investigation of the Acfer 094 carbonaceous chondrite, lakargiite (CaZrO3) was identified as submicrometer inclusions in an isolated hibonite grain in section USNM 7233-1. The hibonite grain is described in Simon and Grossman [1]. Lakargiite is a recently found perovskite-group mineral from hightemperature skarns in ignimbrites of the Upper-Chegem volcanic...

Cryogenic weathering is a key driver of periglacial sediment composition and properties. Selective mineral-grain caused by freeze-thaw cycles in permafrost environments has the ability to dominate this process, leading silt-rich grain-size distributions. The cryogenic index (CWI) promising tool quantify freezing conditions. It considers low resistance quartz compared feldspars. Using approach, ...

Although the nitrogen nutrition index (NNI) is a widely used indicator of plant nitrogenstatus, no model of NNI calculation for spring barley (Hordeum vulgare) reflecting also specificmalting requirements on grain has been published. The aim of this study was to determinean optimal range of the nitrogen nutrition index (ratio of nitrogen concentration in shootbiomass to critical nitrogen concen...

Mineral nutrient malnutrition, particularly deficiency in zinc and iron, afflicts over 3 billion people worldwide. Biofortification of food crops is the best approach for conciliating the micronutrient deficiencies. Understanding the genetic basis of their accumulation is the preconditions for enhancing of these micronutrients. In our study, a mapping population of a set of 118 recombinant inbr...

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...
