To better understand how residue quality and seasonal conditions influence the flow of C from both root and straw residues into the soil microbial community, we followed the incorporation of C-labeled crimson clover (Trifolium incarnatum) and ryegrass (Lolium multiflorum) root and straw residues into the phospholipid fatty acids (PLFA) of soil microbial biomass. After residue incorporation unde...

Sulfuryl fluoride is a colorless, odorless gas used as fumigant against pests during the storage of durable agricultural products. It also one alternatives to methyl bromide, which banned by Montreal Protocol. During fumigation, decomposition product sulfuryl residue can be formed in addition residue. Fluoride actually natural ingredient tea plant. However, within growing process plant concentr...

background: tetracyclines (tcs) are broad-spectrumantibiotics that are widely used in veterinary medicine. thepresence of tcs residues in milk is a public health concern allover the world. objectives:this study aimed to determine tcsresiduals in pasteurized milk marketed by some dairy companiesin tehran from april 2011 to march 2012. methods: 432pasteurized milk samples were purchased from supe...

Soil organic carbon (SOC) turnover plays a pivotal role in achieving C neutrality, promoting retention and increasing soil fertility. Residue biochemistry texture essentially determine SOC distribution (including CO2 mineralization stock soil) farmland. However, less is known about allocation of residue-C with contrasting the fate under two different textures. This study was conducted 61-day ae...

BACKGROUND Climate change scenarios that include precipitation shifts and nitrogen (N) deposition are impacting carbon (C) budgets in arid ecosystems. Roots constitute an important part of the C cycle, but it is still unclear which factors control root mass loss and nutrient release in arid lands. METHODOLOGY/PRINCIPAL FINDINGS Litterbags were used to investigate the decomposition rate and nu...

The theory of algebraic hierarchical decomposition of finite state automata is an important and well developed branch of theoretical computer science (Krohn-Rhodes Theory). Beyond this it gives a general model for some important aspects of our cognitive capabilities and also provides possible means for constructing artificial cognitive systems: a Krohn-Rhodes decomposition may serve as a formal...

Abbreviations: AI, acid insoluble; AS, acid soluble; SOC, soil organic carbon; SOM, soil organic matter. Understanding the interaction between plant components and their subsequent decomposition provides insights on how plant quality differences may infl uence C sequestration within a given management system. Our hypothesis was that decomposition is a function of biochemical composition when al...

For a smooth and proper scheme over an Artinian local ring with ordinary reduction the perfect residue field, we prove — under some general assumptions that relative de Rham–Witt spectral sequence degenerates crystalline cohomology, equipped its display structure arising from Nygaard complexes, has Hodge–Witt decomposition into direct sum of (suitably Tate-Twisted) multiplicative displays. As e...

We have reviewed information on early-, late- and limit-value decomposition stages for litter of Norway spruce (Picea abies) Scots pine (Pinus silvestris). This synthesis covers c 16 studies/papers made along a climatic gradient; range in mean annual temperature (MAT) from ?1 to +7 °C precipitation (MAP) 425 1070 mm. has an early stage dominated by carbohydrate late lignin; just one lignin deco...
