Four, lactating dairy crossbreds (50%×50% Holstein Friesian×Native Zebu cattle) were randomly assigned according to a 2×2 factorial arrangement (two protein levels and two levels of mangosteen peel pe...
The effects on reproduction of African catfish (Clarias gariepinus Burchell 1822) were investigated in three experiments conducted under controlled conditions, carp pituitary (at the dose of 4 mg/kg b...
We used a moored upward-facing 200 kHz echo sounder to address sedimentation of fecal pellets (FPs) from dielly migrating Meganyctiphanes norvegica. The echo sounder was located on the bottom at 150 ...
A chromatographic method and a dynamic Wicke-Kallenbach method (DMWK) were used to determine the diffusion characteristics of two industrial copper containing catalysts. The first catalyst was used in...
A growth and digestibility study was conducted using Osmanabadi goat male kids by feeding complete diets in the form of mash or expander extruded pellets containing different levels of red gram (Cajan...
Radioisotope concentrations, such as 238U and 232Th, of bulk sediments are good environmental indicators and useful for radiometric age determinations. Pressed pellets of sediment can be analyzed by ...
The biosorption of lead ions from aqueous solution on a self-immobilized Rhizopus nigricans biomass has been studied. Experiments were performed in a laboratory scale packed bed column at different ...
Many companies in the U.S. are entering the wood pellets market due to the increasing importance of woody biomass utilization for energy purposes. Despite a 200% increase in U.S. production, it is dif...
采用单因素试验和正交试验设计,以乳酸质量浓度及菌丝形态为考察指标,对米根霉首批发酵培养基及补料培养基进行优化,得到适于米根霉半连续发酵的培养基,建立了米根霉半连续发酵工艺,并进行米根霉半连续发酵产乳酸的稳定性试验。得到首批培养基参数为葡萄糖120g/L,(NH4)2SO4 2g/L,NaH2PO4 0.16g/L,KH2PO4 0.14g/L,MgSO4?7H2O 0.2g/L,ZnSO4?7H2...
To develop a reforestation method for devastated land, the author investigated the behavior of seeds in clay pellets as reforestation materials in the Matsukisawa Basin in Ashio. In the case of a seed...
Establishment of Rice Seedlings by Direct Sowing of Multiple Seed Pellets on Paddy Soil Covered with Legume Living Mulch.
Fungal mycelium pellets of Aspergillus niger 405 were used for adsorption of different metal ions. The biosorption of Cu2+, Zn2+, Ni2+ and CrO42- was studied over a range of metal ion concentrations, ...
The use of high technology in the manufacture of pellets and their use in modern furnace chambers of boiler plants for remote heating and heating of family houses, are the reason why pellets as the ...
Conversion of testosterone to dihydrotestosterone (DHT) by the action of 5alpha-reductase can amplify androgen action. This may be of particular importance in the presence of low testosterone concentr...
We analyzed size-specific dry mass, sinking velocity, and apparent diffusivity in field-sampled marine snow, laboratory-made aggregates formed by diatoms or coccolithophorids, and small and large zoo...
