Neoplastic transformation is a complex process that results from multiple changes in gene activities. Probably most of these are mutational, i.e. alterations in the genomic structure of DNA, but others may be due to adaptive changes wherein genes are expressed that are inappropriate to a stage of development or differentiation. In this commentary neoplastic development is discussed in the conte...

Since the halophytes species have an important role in such ecosystem balance and they have been grazed by livestock as supplementary forage, the awareness of livestock's desire to grazing and their preference values of these species is of high priority. Regardless of the importance of halophyte species in the livestock feeding in Iran, there is less published research on the livestock grazing ...

Livestock grazing is one of the most important factors influencing the above-ground community composition and structure in a natural grassland ecosystem. Different grazing intensities also have the potential to alter soil C and N storage substantially in grasslands. We conducted a field community study and soil analyses to determine the effects of different grazing intensities on the above-grou...

Vegetation composition and reproduction of vascular plants were studied in relation to seven spatial structures: Betula pendula, Pinus sylvestris, Juniperus communis, Rosa dumalis, dung pats, grazing rejects and grazed patches. Th e study was performed in 14 unfertilized semi-natural pastures, with diff erent grazing intensities, in southcentral Sweden. Vegetation height diff ered between sites...

In spite of overwhelming experimental evidence to the contrary, rotational grazing continues to be promoted and implemented as the only viable grazing strategy. The goals of this synthesis are to 1) reevaluate the complexity, underlying assumptions, and ecological processes of grazed ecosystems, 2) summarize plant and animal production responses to rotational and continuous grazing, 3) characte...

Questions Management practices in permanent grasslands affect plant community structure and thus resources for both the herbivore decomposer subsystems. While their effects on digestibility or litter decomposition had been studied separately, few, if any, studies have tested responses simultaneously underlying relationships with functional structure. We whether mass ratio hypothesis niche compl...

le mouvement transversal de la locomotive ou des wagons , appele ie lacet, provient de deux causes principales: -la conicite des bandages -les irregularites de la voie dans ie plan horizontal. on se propose ici d'etudier la premiere cause , ce qui nous conduit a une equation differentielle non lineaire du deuxieme ordre. • l'equation en question est etudiee dans plusieurs cas difftten...

We design and release BONIE, the first open numerical relation extractor, for extracting Open IE tuples where one of the arguments is a number or a quantity-unit phrase. BONIE uses bootstrapping to learn the specific dependency patterns that express numerical relations in a sentence. BONIE’s novelty lies in task-specific customizations, such as inferring implicit relations, which are clear due ...

Information extraction (IE) systems have been tailored to extract fixed target information from documents in a fixed language. In order to be truly useful for information analysts, the target information must be user-definable and the source documents should cover multiple languages. We will map out the path toward such open-target multilingual IE systems, identifying necessary technological br...

Soil bacteria play a key role in the ecological and evolutionary responses of agricultural ecosystems. Domestic herbivore grazing is known to influence soil bacterial community. However, the effects of grazing and its major driving factors on soil bacterial community remain unknown for different plant community compositions under increasing grazing intensity. Thus, to investigate soil bacterial...
