A number of recent works have investigated the notion of “computational fields” as a means of coordinating systems in distributed, dense and mobile environments such as pervasive computing, sensor networks, and robot swarms. We introduce a minimal core calculus meant to capture the key ingredients of languages that make use of computational fields: functional composition of fields, functions ov...

smirnovia iranica (sabeti) synonym: smirnovia turkestana (bunge) is a deciduous perennial bushy species of the fabaceae (papilionaceae) family. the species grow on sand dunes of desert areas, having a deep vertical root and very long horizontal or lateral roots. they have an important role in natural vegetation of desert and sand dune stabilization. limited growing areas, grazing due to good pa...

this paper concerns the problem of robust stabilization of uncertain fractional-order non-autonomous systems. in this regard, a single input active control approach is proposed for control and stabilization of three-dimensional uncertain fractional-order systems. the robust controller is designed on the basis of fractional lyapunov stability theory. furthermore, the effects of model uncertainti...

Soil carbon sequestration is strongly affected by soil properties, climate, and anthropogenic activities. Assessing these drivers is key to understanding the effect of land use on soil organic matter stabilization. We evaluated land use and soil depth influencing patterns of soil organic matter stabilization in three types of soil profiles located under the same pedogenetic matrix and alpine co...

compounds derived from lipid oxidation endangering human health and lead to cardiovascular disease and cancer. the addition of antioxidants is effective in retarding the oxidation of lipids and lipid containing foods. due to the toxicological effects of synthetic antioxidants, decrease their use and replacing them with natural antioxidants. this study investigates antioxidant effect of pimpinel...

The prebiotic significance of laboratory experiments that study the interactions between oligomeric RNA and mineral species is difficult to know. Natural exemplars of specific minerals can differ widely depending on their provenance. While laboratory-generated samples of synthetic minerals can have controlled compositions, they are often viewed as "unnatural". Here, we show how trends in the in...

Density functional (DFT) calculations at M05-2x/aug-cc-pVDZ level were used to analyze the interactions between dimethyl sulfoxide (DMSO) dimers. The structures obtained have been analyzed with the Atoms in Molecules (AIMs) and Natural Bond Orbital (NBO) methodologies. Four minima were located on the potential energy surface of the dimers. Three types of interactions are observed, CH•••O, CH•••...

The technique of soil stabilization is usually adopted with the purpose of rendering plastic soils coherent to the standards and requirements of engineering projects. The environmental benefits of soil stabilization versus the use of traditional natural material from quarries are generally underestimated. The case study of one significant section of the Italian High Speed Railway is presented h...

An increasing ecological awareness and greater efforts on a global scale to reverse processes of environmental degradation give rise to new forms of social and economic conflict-a "politics of resource stabilization"-which political ecology theorists have yet to fully explore. Blaikie and Brookfield (1987) argue that the long-term payback period of capital-intensive and natural reclamation proc...
