Probiotics have been proved to be the most preferred and effective alternative antibiotics as growth promoter pathogens inhibitor in poultry industry. In this study Bacillus subtilis CGMCC 1.1086 a probiotic bacterium was administered diet its effects on both performance caecal microbiota of broilers were evaluated.A total 240 male Arbor Acres (AA) randomly allocated into two treatment groups basal without any addition probiotics containing B. 1.1086. The body weight measured individually at...
The characteristics and kinetics of iron oxide reduction by carbon in biomass composites were studied. Iron can be reduced very rapidly, the degree metallisation increases with temperature. divided into two stages: volatile followed non-volatile carbon. times stages both decrease increasing first is controlled gas diffusion, whereas second stage dominated gasification.
The purpose of this study was to determine the positive effects potassium-solubilizing bacteria and photosynthetic on salt tolerance maize.We selected maize inbred lines USTB-265 (salt-sensitive), USTB-109 (moderately salt-tolerant) USTB-297 (salt-tolerant) investigate their growth characteristics, enzyme activity gene expression in response inoculation with under salt-stress conditions.Photosynthetic significantly enhanced antioxidant enzyme-related genes increased activities enzymes...
Chinese, one of the oldest languages in world, are being used by 1.5 billion people across world. Comparatively, due to substantial ambiguity structure human language, especially there is still not a complete and practical Chinese detecting syntactic error system which helps us avoiding common mistakes. Current systems for fight many problems including high parser output. In this paper, we provide new but method deal with grammar errors. Here arrange anew rules combined character...
(i) To obtain and identify the predatory bacteria for control of contaminated to promote autotrophic growth Chlorella USTB‐01. (ii) measure different cell numbers in microalgal culture using flow cytometer. A bacterial strain was isolated Escherichia coli BL21 as a sole prey host, which identified Bdellovibrio USTB‐06 by analysis 16S rDNA sequence. cytometer successfully used USTB‐01, simultaneously USTB‐01 according identification sizes. With addition at initial 104 plaque‐forming units per...
Population densities in cities of developing countries are much higher than other parts the world, and predominance poverty urban slums is ubiquitous throughout region. In many areas, lack wastewater waste management continues to be a huge challenge for environment health protection. Decentralized approaches proposed provide practical, alternative options sustainable conditions. Conventionally, on-site constructed brick/concrete biogas reactors most used models. However, long construction...
Research on the novel technology of fluidized roasting reduction low-grade pyrolusite coupling with pretreatment stone coal has been conducted. According to response surface design and analysis results, orthogonal experiments have conducted major factors effects manganese efficiency studied. The quadratic model between established. Meanwhile, contour or 3D among various presented. maximum could be optimized nearly 100%, when mass ratio was 2.5:1, temperature 1080?C, 775?C, time 2h. results...
Blood centers in large hospitals China are facing serious problems, including complex patient queues and inflexible nursing schedules. This study is aimed at developing a flexible scheduling method for blood center nurses. By systematically analyzing the constraints that affect scheduling, model established based on queuing theory mixed integer programming. combined can reasonably determine number of nurses required during given working period flexibly arrange schedules while ensuring...
This paper integrates non-cyclical preventive maintenance and tactical production planning into a multi-product system. In such system, set of products needs to be produced in lots during specified finite horizon. Non-cyclical is carried out at the end some periods corrective always performed failure. Both activities setup result downtime Procedures are proposed discover optimal plan sequence simultaneously, our objective being minimize sum maintenance, production, inventory, backorder costs...
Grammar proofreading is one of the most important parts Chinese natural language processing. It makes studies difficult because complicated and flexible. Studies about processing have made some achievements domestic overseas, but cross-sentences grammar has not had an effective solution. proposes arithmetic called "Entire-Sentence" to cut sentence more completely solve problem method cross sentences based on LanguageTool. Moreover, paper also presents new rules which can accomplish improve...
Three‐dimensional morphology of eutectic silicon in as‐cast Al‐20 wt% Si alloys with ultrasonic treatment above liquidus has been investigated this paper. The results show that could not refine the primary phase very well, but is capable modifying silicon. fracture occurred resulting both huge reduction grain sizes and changes from large plate‐like to interconnected thin flake coral‐like. evolution mechanisms were also preliminarily discussed.
Fines generation of lump coal is a most important limiting factor for efficient production in the COREX process. In this paper, fines has been examined based on simulation experiments relationships char conversion with temperature and heat absorption. According to results, early stage coke formation melter gasifier, absorbs large amounts but without significant increase its high strength. Strength was only improved at later stages forming Residual also found tuyere samples illustrating that...
The Australian Pilbara blend lump ore, which entered the Chinese market in 2007, is a special blending ore. To master its behavior and effect BF adequately, metallurgical properties high temperature reactivity of ore six other kinds were researched. reasonable proportion mixing pattern was studied by carrying out softening dropping property tests, this provides technological support for practical production.
An integrated cost model for jointing preventive maintenance (PM) and economic production quantity (EPQ) in a multi-product system is proposed this paper. Assume the horizon finite, which composed of several cycles, some types products should be produced lots within cycles. For less disturbing to process, according situation reality, we also assume PM done at setup time epoch. The demand adjusted because downtime caused by random. objective paper optimize EPQ schedule through minimizing...
Abstract Die Werkstoffe Nr. 1.4301, 1.4571, 1.4439 und 1.4558 wurden bei Raumtemperatur in kalter Salzsäure (c(Cl − ) = 1,5 mol/L c(H + 1 mol/L, vereinzelt auch 0,1 0,01 mol/L) untersucht. Potentiostatische Halteversuche ergeben Daten für aktive Korrosion, Passivität Lochkorrosion. CERT‐Versuche (10 −6 s −1 , 2 · 10 −7 freier Korrosion zeigten eine Überlagerung zwischen transkristallinem Angriff gleichförmigem Flächenabtrag, wobei das Ruhepotential verhältnismäßig negativen Potentialen im...
