Abstract:

AbstractSome selected concepts of the solar activity cycle are reviewed. Cycle modulations through a stochastic α effect are being identified with limited scale separation ratios. Three-dimensional turbulence simulations with helicity and shear are compared at two different scale separation ratios. In both cases the level of fluctuations shows relatively little variation with the dynamo cycle. Prospects for a shallow origin of sunspots are discussed in terms of the negative effective magnetic pressure instability. Tilt angles of bipolar active regions are discussed as a consequence of shear ra

Abstract:

This research was motivated by the low understanding of Mathematics concepts in class III students at SDN 004 Salo. This is because the learning model has not been able to improve students' understanding of Mathematics concepts in the learning process. One solution to overcome this problem is to apply the Concept Attainment learning model . This research aims to describe increasing students' understanding of Mathematics concepts by applying the Concept Attainment learning model for class III students at SDN 004 Salo. This research method is classroom action research (PTK) which is carried out

Abstract:

In Technology there are many life cycles from various aspects and classified into different categories. Product life cycle is simple and basic life cycle for any product. This is the base for development of many other life cycles. But in literature different life cycles like Product life cycle, Technology life cycleand Industry lifecycles are often considered as interchangeable concepts though it is inappropriate. So, this paper enlightens the differences between these concepts. This study tries to understand some theoretical insight of Technology life cycle. This Study also focuses on differe

The nucleolus is a large nuclear domain and the site of ribosome biogenesis. It is also at the parting of the ways of several cellular processes, including cell cycle progression, gene silencing, and ribonucleoprotein complex formation. Consequently, a functional nucleolus is crucial for cell survival. Recent investigations of nucleolar assembly during the cell cycle and during embryogenesis have provided an integrated view of the dynamics of this process. Moreover, they have generated new ideas about cell cycle control of nucleolar assembly, the dynamics of the delivery of the RNA processing

Abstract:

This paper proposes to establish a relationship between the Stirling numbers of the first kind and the cycle types of Sn, exhibiting the feasibility of a procedure to generate Stirling numbers of the first kind and proving some identities by the combination of these two concepts. This is possible due these numbers’ strong algebraic appeal, given that we can define them as the number of permutations of Sn that decompose into exactly k disjoint cycles. There is a bijective relationship between the cycle types of Sn and the partitions of a positive integer n, thus given a partition of n, we know

This article is based on an exploratory research regarding Life Cycle Assessment (LCA), an environmental management tool towards product system. It was analyzed its origin, concepts, benefits, barriers, methodology and its implementation in Brazil during the last decades. Based on the results, it was observed that in order to apply this tool in Brazil it is necessary to acquire more experience in its use. Besides that, it is essential that there be a standardization of its methodology and government incentives. Therefore, it is observed that the LCA adoption represents an important strategic c
