Matrix-assisted laser desorption/ionisation (MALDI) mass spectrometry was investigated for the simultaneous detection of several metabolites, as applicable to global metabolite analysis (metabolomics). The commonly employed organic matrices alpha-cyano-4-hydroxycinnamic acid and 3,5-dihydroxybenzoic acid, in both the crystalline and ionic liquid forms, were investigated. The employment of a low...

a primary uses from iran rangelands is livestock grazing and the major livestock is sheep. sheep grazing on the slopes above 60%, because of using a lot of energy for grazing operation, caused to not only reduces livestock performance but also increases the risk of erosion. sheep grazing in an area where more than five kilometers away from water sources, due to the prolongation of the march rou...

Soil is a vital parameter for planting design in urban green spaces especially in adverse climate conditions. In this study, the utilization of analytic hierarchy process (AHP) in surveying land suitability for urban green space from measured criteria like suitability indices, including physical (i.e. clay, silt, sand, bulk density, penetration resistance), chemical (i.e. electrical conductivit...

Abstract We present the development and characterization of a high-stability, multi-material, multi-thickness tape-drive target for laser-driven acceleration at repetition rates up to 100 Hz. The tape surface position was measured be stable on sub-micrometre scale, compatible with high-numerical aperture focusing geometries required achieve relativistic intensity interactions pulse energy avail...

water resources suitability is one of the most important factors to sustainabilityutilization of natural potential by rangeland grazing suitability. to determine this factor inshort time, low cost and high accuracy are most challenges of experts and ranchers. usingsuitable technique for this subject can be sustainable utilization comprising from rangelandecosystems according to its degradation ...

Fuzzy clustering is a data analysis technique that, when applied to a set of heterogeneous items, identifies homogenous subgroups as defined by a given model or measure of similarity in fuzzy environment. Moreover, fuzzy clustering methodology has been developed and used in variety of areas like biology, computer science, engineering, medicine etc. In this paper, fuzzy cluster model is develope...

The construction of habitat models is a repeatable technique for describing and mapping species distributions, the utility of which lies in enabling management to predict where a species is likely to occur within a landscape. Typically, habitat models have been used to establish habitat requirements for threatened species; however they have equal applicability for modelling local populations of...

The aim of this study is to develop a method by means of which it is possible to produce georeferenced ecological information about the habitat requirements of different species. The integrated habitat suitability index approach includes the steps of constructing habitat suitability models, producing data needed in models, evaluating of target areas based on habitat factors, and combining vario...
