The trapping effect is eliminated when nc-Ge is synthesized in forming gas thus excluding the possibility of qua... | A single transistor memory structure, with changes in threshold voltage exceeding /spl ap/0.25 V corresponding to single electron storage in individual nano-crystals, operating in the sub-3 V range, and exhibiting long term to non-volatile charge storage is reported. As a consequence of Coulombic effects, operation at ... | Increases in nitrogen (N) deposition can greatly stimulate ecosystem net carbon (C) sequestration through positive N-induced effects on plant productivity. However, how net ecosystem CO2 exchange (NEE) and its components respond to different N addition rates remains unclear. Using an N addition gradient experiment (six... | eng_Latn | 9,493 |
This paper addressed the spatial distribution characteristics of organic matter, total nitrogen, extractable phos phorus and extractable potassium in agricultural soils of Northeast China. The related factors were explored using geostatistics and geographic information systems. The results showed that the log-transform... | Spatial distributions of soil properties at the field and watershed scale may affect yield potential, hydrologic responses, and transport of herbicides and NO to surface or groundwater. Our research describes field-scale distributions and spatial trends for 28 different soil parameters at two sites within a watershed i... | Phosphorus (P) is an essential nutrient required by plants for normal growth and development. The availability of P to plants for uptake and utilization is impaired in alkaline and calcareous soil due to the formation of poorly soluble calcium phosphate minerals. Adding fertilizer P at “normal” rates and with conventio... | eng_Latn | 9,494 |
Carbon is sequestered by the plant photosynthesis and stored as biomass in different parts of the tree. Carbon sequestration rate has been measured for young species (6 years age) of Shorea robusta at Chadra forest in Paschim Medinipur district, Albizzia lebbek in Indian Botanic Garden in Howrah district, Tectona grand... | Source apportionment study at Madurai Kamaraj University was done to identify the possible sources of black carbon concentration (BC). It was found that the biomass burning resulted in the increase of BC mass concentration. As biomass was the primary source of fuel for most of the rural households around the educationa... | We prove that groups acting geometrically on delta-quasiconvex spaces contain no essential Baumslag-Solitar quotients as subgroups. This implies that they are translation discrete, meaning that the translation numbers of their nontorsion elements are bounded away from zero. | eng_Latn | 9,495 |
In the near future phosphorus (P) will be a limited resource in high demand. This will increase the incentives for recycling P in animal manure. In this study the dry-matter-rich fraction from slurry separation was incinerated and the P availability of the ash fraction examined. The aim was to adjust incineration tempe... | The objectives of this article are to offer a comprehensive evaluation of the opportunities and barriers for swine manure conversion technologies and to shed light on the gaps that might require further investigation to improve the applicability of these technologies. The challenges of manure management have been propa... | Ciliated protozoa may be preserved at very low temperatures. Tetrahymena pyriformis, suspended in 10 percent dimethylsulfoxide, survived when frozen in two steps, first to -20 ° C, then transferring immediately to a temperature of -196 ° C. Motility and ability to reproduce were recovered after freezing by this method ... | eng_Latn | 9,496 |
A technique for optimising reagent concentrations on the AutoAnalyzer has been applied to the estimation of ammonia by the Berthelot reaction in the determination of urea and organic nitrogen. Comparison of the use of phenol and salicylate revealed that the optimum concentration of the latter is about four times that o... | The interactions between ammonium fertilization, cyanide (KCN) assimilation and proline accumulation in rice seedlings (Oryza sativa L. cv. XZX 45) were investigated during the current investigation. Results indicated that rice seedlings possess effective assimilation potential for exogenous CN− after 2-d exposure, whe... | Long-term (1987-2012) water quality monitoring in 36 acid-sensitive Swedish lakes shows slow recovery from historic acidification. Overall, strong acid anion concentrations declined, primarily as a result of declines in sulfate. Chloride is now the dominant anion in many acid-sensitive lakes. Base cation concentrations... | eng_Latn | 9,497 |
Industrialisation and urbanization leads to an increase in concentration of greenhouse gases, which eventually alters the radiation balance of the climate system. Urban regions are hotspots of greenhouse gas emissions which include CO 2 , CH 4 , N 2 O, etc. Methane emitting sources hosted by cities include fossil fuel ... | 1.

Most of what we currently know about UNC-45A pertains to its role as a regulator of the actomyosin system... | eng_Latn | 9,498 |
Publisher Summary No-till seeding is essential for soil erosion control, reducing seeding costs, and protecting or enhancing soil quality. The ability for specific residues to protect against soil erosion depends on quantity, their chemical composition, and management. These characteristics and properties determine the... | SUMMARY Cultural practices such as tillage and crop rotation can be used as components of pest-management programs. The appropriate combination of tillage systems and crops may favor the development of beneficial microorganisms, preventing the spread of fungal pathogens. A long-term field study was carried out to analy... | Perfect Quantum Cloning Machines (QCM) would allow to use quantum nonlocality for arbitrary fast signaling. However perfect QCM cannot exist. We derive a bound on the fidelity of QCM compatible with the no-signaling constraint. This bound equals the fidelity of the Bu\v{z}ek-Hillery QCM. | eng_Latn | 9,499 |
