small-scale dairy farming in bangladesh is constrained mostly due to acute shortage, high price and seasonal fluctuation of energy and protein supplements. poor economic conditions of dairy farmers do not allow them to purchase adequate conventional energy and protein supplements. locally available non-conventional energy and protein sources can be used as alternatives, cheaper than conventiona...

To decrease total system cost and improve efficiency, in future mobile communication systems, we can implement a structure of multiple cells covering an area. This is often referred to as a Hierarchical Cell Structure, HCS. We compare five methods of sharing the scarce radio resources in a two layer HCS: I) DS-CDMA in macro cells and TDMA in micro cells, II) TDMA in macro cells and DS-CDMA in m...

BACKGROUND Adequate dietary intake is essential to maintain good health. This is particularly true for the elderly. This study investigated the dietary intakes of seniors residing in Newfoundland and Labrador (NL) and assessed the adequacy of nutrients which they consumed as food. METHODS Between November 2012 and January 2013, we recruited senior residents in NL, aged 65 years or older Parti...

This study shows the effect of soil structure, soil texture and different types of nutrients on the growth of Ammi visnaga (L.) Lam, as well as the yield of the fruit crop and its content of the main active principals (ɣpyrones). The study was carried out in several localities in Two Arabian countries in North Africa; Egypt and Sudan. Egypt: at three localities:-1st at Mepaco Farm in Enshas El-...

a brief overview of the historical development of ergonomics in organizational design and management (odam) is presented. as a component of technology or ergonomics, macro ergonomics are described as a systematic. scientifically based means of optimizing work system  design. macro ergonomics  might  be reoffered  to  as: organization - environment - human - machine interface technology. involve...

Chemistry knowledge can be represented at macro-, microand symbolic levels, and learning a chemistry topic requires students to engage in multiple representational activities. This study focused on scaffolding for inter-level connection-making in learning chemistry knowledge with graphical simulations. We also tested whether different sequences of representational activities produced different ...

To provide sufficient capacity in traffic hot spots, small micro cells are needed to complement macro cells providing low cost large area coverage. These problems can be solved by using a mixed cell structure with macro cells for coverage and micro cells for capacity. Such a scenario, where coverage is provided from both macro and micro cells in a large part of the service area, is often referr...

Reductionism assumes that causation in the physical world occurs at the micro level, excluding the emergence of macro-level causation. We challenge this reductionist assumption by demonstrating that, once causal power is properly defined and measured, it is possible for a macro level to “beat” the micro level. Here, this was done through a principled, well-defined measure of intrinsic cause-eff...

An important issue regarding the deeper understanding of social and organisational phenomena is the interaction and the linkage between micro and macro layers. The micro-macro-link deals with the emergent aggregation of processes and actions on the micro-level and with structures, rules and roles on the macro-level. This paper presents recent results of the “socionics” project ASKO, which is a ...

In this address, I revisit the micro–macro problem in criminology, arguing for an “analytical criminology” that takes an integrated approach to the micro– macro problem. I begin by contrasting an integrated methodological-individualist approach with traditional holist and individualist approaches. An integrated approach considers the concept of emergence and tackles the difficult problem of spe...
