Clover Content

Two varieties of tall fescue were compared with 'Grasslands Ariki' ryegrass as feeds for lactating, and growing catmtle. In three shortterm experimeats the dairy cows grazing the different types of pasture produced similar quantities of milk and in most cases the fat and protein contents did not differ significantly. On the other hand, the exclusion of clover from the grass swards led to a lower milk production. Liveweight gains were consistently higher for yearling cattle grazing Ariki ryegrass compared with the two fescue swards. The invitro digestibility of S170 was lower than the value for G4710 but because of the high clover content of the S170 pastures animal performance was similar.

Clear Differentiation

The article proposes the results of studying the influence of various types of cattle grazing on the content of mobile forms of phosphorus (P2O5), potassium (K2O), organic matter (C,%) and Ph rate. It has been found out that with different types of cattle grazing, clear differentiation of the agrochemical state within the land plots is manifested. The degree of vegetation cover digression is characterized by a significant decrease in the species composition depending on the type of cattle grazing. Various levels of interrelation between the type of cattle grazing and observable dynamics of changes in the ecological functions of soil cover and their influence on the structure of the digression levels formation are designated in the article. The obtained results based on the conclusions of this article may serve as one of the options for conducting research on the assessment of destructive anthropogenic activity. For the most effective protection of soil cover of territories exposed to livestock impact, it is necessary to develop agrotechnical complexes. It has been discovered that real loads as a result of uncontrolled and periodic cattle overgrazing are 10 times higher than the maximum permissible norms that manifests itself in intense and significant violation of a natural ecosystem.

The Laplace transform of the extinction time is determined for a general birth and death process with arbitrary catastrophe rate and catastrophe size distribution. It is assumed only that the birth rates satisfyλ0= 0,λj> 0 for eachj> 0, and. Necessary and sufficient conditions for certain extinction of the population are derived. The results are applied to the linear birth and death process (λj=jλ, µj=jμ) with catastrophes of several different types.

Abstract We argue that Tomasello's account overlooks important psychological distinctions between how humans judge different types of moral obligations, such as prescriptive obligations (i.e., what one should do) and proscriptive obligations (i.e., what one should not do). Specifically, evaluating these different types of obligations rests on different psychological inputs and has distinct downstream consequences for judgments of moral character.

Complete Interpretation

Previous freeze fracture results on the intact giant, amoeba Chaos carolinensis indicated the presence of a fibrillar arrangement of filaments within the cytoplasm. A complete interpretation of the three dimensional ultrastructure of these structures, and their possible role in amoeboid movement was not possible, since comparable results could not be obtained with conventional fixation of intact amoebae. Progress in interpreting the freeze fracture images of amoebae required a more thorough understanding of the different types of filaments present in amoebae, and of the ways in which they could be organized while remaining functional.The recent development of a calcium sensitive, demembranated, amoeboid model of Chaos carolinensis has made it possible to achieve a better understanding of such functional arrangements of amoeboid filaments. In these models the motility of demembranated cytoplasm can be controlled in vitro, and the chemical conditions necessary for contractility, and cytoplasmic streaming can be investigated. It is clear from these studies that “fibrils” exist in amoeboid models, and that they are capable of contracting along their length under conditions similar to those which cause contraction in vertebrate muscles.
