We explore statistical inference in self-similar conservative fragmentation chains, when only (approximate) observations of the size of the fragments below a given threshold are available. This framework, introduced by Bertoin and Martinez, is motivated by mineral crushing in mining industry. The underlying estimated object is the step distribution of the random walk associated to a randomly ta...

Over recent decades, electromagnetic methods have been viewed with considerable suspicion by many in the hydrocarbon exploration industry. While highly effective in mineral and environmental geophysics, electro m a g n e t i c methods have played a minor role in hydrocarbon exploration. Since electromagnetic (EM) methods use signals that diffuse in the Earth, they cannot provide the same vertic...

The monocotyledonous Dioscorea genus is known as yam. Many species of Dioscorea genus are economically important crops of worldwide and many of them have been used in the pharmaceutical industry. In vitro propagation of Dioscorea species pave the way to meet the demand of this economically important plant. The protocols are designed to provide the optimal levels of mineral nutrients, environmen...

background: noise induced hearing loss (nihl) is the highest reported occupational disease among industrial workers but there is scarcity of data on disease burden in malaysia. this study estimated the risks and burden of nihl in manufacturing industries in malaysia. methods: this cross-sectional industrial survey was conducted by interviewing osh practitioners at 26 industries categorized as f...

Dip-coated films, which are widely used in the coating industry, are usually measured by capacitive methods with micrometric precision. For the first time to our knowledge, we have applied an interferometric determination of the evolution of thickness in real time to nonvolatile Newtonian mineral oils with several viscosities and distinct dip withdrawing speeds. The evolution of film thickness ...

Most dairy farms in Wisconsin continue to follow a fairly generalized formula of how to produce milk. Cows and replacement heifers are fed primarily homegrown feed from crop rotations comprising alfalfa (Medicago sativa L.), corn (Zea mays L.), oats (Avena spp.) and soybean (Glycine max L. Merr.). Protein and mineral supplements are purchased to compliment dairy diets. However, the dairy indust...

A worldwide survey on grinding mill circuits in the mineral processing industry was conducted. The aims of this survey are to determine how milling circuits are currently controlled, and to find out how key process variables are linked to economic benefits. The survey involves background information on the circuits, the choice of controlled and manipulated variables, the economic impact of the ...

Some of the major issues faced by the poultry industry are about; improving efficiency of production, reducing environmental pollution resulted from litter and reducing food cost. In general, to meet these challenges, series of attempts have been made by researchers. Some of them are inclusion of food additives to improve growth performance, reduction of specific nutrient concentration or manip...

Industrial structure is one of the main factors that determine energy consumption. Based on China’s energy consumption in 2015 and the goals in 13th Five-Year Plan for Economic and Social Development of the People’s Republic of China (The 13th Five-Year Plan), this paper established an input–output fuzzy multi-objective optimization model to estimate the potential impacts of China’s industrial ...

The comminution process, particularly grinding, is very important in the mineral processing industry. Some characteristics of ore particles, which occur as a product of grinding process, have a significant impact on the effects of further ore processing. At the same time, this process requires a significant amount of energy which significantly affects the overall processing costs. Therefore, in...
