Biochar, a green way to deal with burning and burying biomass, has attracted more attention in recent years. To fill the gap of the effects of different biochar on crop yield in Northern China, the first field experiment was conducted in farmland located in Hebei Province. Biochars derived from two kinds of feedstocks (rice straw and corn stalk) were added into an Inceptisols area with differen...

We prove that every homomorphism O ζ → O ζ , with E and F Banach spaces and ζ ∈ C, is induced by a Hom(E,F )-valued holomorphic germ, provided that 1 ≤ m < ∞. A similar structure theorem is obtained for the homomorphisms of type O ζ → Sζ , where Sζ is a stalk of a coherent sheaf of positive mζ -depth. We later extend these results to sheaf homomorphisms, obtaining a condition on coherent sheave...

If you have never entered the world of subcontracting it seems a puzzling blend of products, rigid selling and in the past has carried a bad reputation. Today, when grooming with different parameters of economies is becoming harder for every industrialist day by day, it is for sure that this disaster of costknitting is affecting one of the upcoming sectors of present commercial age and that is ...

In this work, Qiqunahu (QQH) coal, cotton stalk, cellulose and lignin extracted from stalk were selected as raw materials to study the effects of co-pyrolysis coal stalk. Online thermogravimetric mass spectrometry (TG-MS) was used analyse loss gas release characteristics during co-pyrolysis. The results reveal that mixture can significantly enhance reactivity blends promote formation effective ...

Norepinephrine, dopamine, and serotonin concentrations in the hypothalamus and stalk-median eminence were estimated in nine Hereford heifers at the onset of oestrus or 48 hr later. Significant differences in levels of monoamines at these stages of the oestrous cycle were not evident. Norepinephrine levels were similar in the hypothalamus and the stalk-median eminence, but dopamine and serotonin...

the use of agriculture residues as filler in composites is increasing due to their strength, abundance and low cost. soya stalks show promising renewable natural fiber. in polyethylene composites the physical and mechanical properties (flexural resistance, tensile, impacted absorbed energy, water uptake and thickness swelling) was examined at different composites. the results showed that, the m...

We use continuum mechanics to calculate an entire least energy pathway of membrane fusion, from stalk formation, to pore creation, and through fusion pore enlargement. The model assumes that each structure in the pathway is axially symmetric. The static continuum stalk structure agrees quantitatively with experimental stalk architecture. Calculations show that in a stalk, the distal monolayer i...

SDF-1 and SDF-2 are peptides that promote terminal spore differentiation under submerged conditions. The present study shows that they accumulate differentially and are released during the development of wild-type cells and can promote spore formation in cells disaggregated from wild-type culminants. SDF-1 accumulates during the slug stage and is released in a single burst at the onset of culmi...

BACKGROUND Tobacco stalk is one kind of abundant crop residues in China. The high lignification of tobacco stalk increases its reusing cost and the existing of nicotine will cause serious pollution. The biodegradation of lignocellulosic biomass has been demonstrated to be an environmental and economical approach for the utilization of plant stalk. Meanwhile, many nicotine-degrading microorganis...
