The hand operated bridge press for ground nut and shea nut processing: A financial and socio-economic appraisal

The present report presents the findings of the socio-economist who visited Ghana in March 1995 as a member of a team to carry out an appraisal of two technologies with potential for field use in Ghana. These were (a) a mincer/extruder for extraction of oil from groundnuts; (b) a bridge press for the extraction of cocoa butter and shea butter

Ideas at Work: a Discursive Institutionalist Analysis of Diversity Management and Social Dialogue in France, Germany and Sweden

This article applies discursive institutionalism (DI) to a comparative analysis of the relationship between diversity management and social dialogue. Schmidt’s (2008, 2010) method of ‘who said what, when and why’ and her concepts of actors’ ‘background discursive’ and ‘foreground ideational’ abilities are used to analyse the dynamic relationship between ideas (diversity management) and the institutional environment (social dialogue and national models of integration). It is argued that diversity management provided an opportunity either to maintain or strengthen existing levels of social dialogue, or to promote a more voluntary, managerial and individualist approach to equality issues. The research demonstrates the merits of DI for providing a fine-grained explanation of the (arguably) counter-intuitive outcomes in France, Germany and Sweden. Another aim is to respond to Hauptmeier and Heery’s (2014) calls for more recognition of the role of ideas in shaping the form, dynamics and products of the employment relationship and HRM

Construction contractors involvement in disaster management planning

Disasters, both natural and man-made, cause major damage and loss of life. Because of this, governments around the world are looking at building resilience to ensure communities can recover quickly and have minimal impact from a disaster. Part of building resilience is to plan for disaster management and recovery. Literature reveals that construction contractors can play a critical role within this process as they have control of resource supply chains and key knowledge and skills they are well suited to assist in disaster planning. However, as literature also reveals there is currently little involvement of construction contractors in the disaster planning process. This gap between what should be done and what is currently done is investigated. Representatives from industry bodies are interviewed to determine their understanding of the industry’s involvement in disaster planning and what capacity the industry might have to be involved. The interviewee’s responses agree with current literature that there is currently little or no involvement with disaster planning however there is interest in being involved with disaster management planning if there was a forum for this to occur. Based on the responses the researcher has proposed a model to engage construction contractors within state government disaster management planning

Analysis of defect structure in silicon. Characterization of samples from UCP ingot 5848-13C

Statistically significant quantitative structural imperfection measurements were made on samples from ubiquitous crystalline process (UCP) Ingot 5848 - 13 C. Important trends were noticed between the measured data, cell efficiency, and diffusion length. Grain boundary substructure appears to have an important effect on the conversion efficiency of solar cells from Semix material. Quantitative microscopy measurements give statistically significant information compared to other microanalytical techniques. A surface preparation technique to obtain proper contrast of structural defects suitable for QTM analysis was perfected

Safety-driven system engineering process

Thesis (S. M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2008.MIT Barker Library copy: leaves 82 to 106 bound upside-down.Includes bibliographical references (leaves 56-59).As the demand for high-performing complex systems has increased, the ability of engineers to meet that demand has not kept pace. The creators of the traditional system engineering processes did not anticipate modern complex systems, and the application of traditional processes to complex systems such as spacecraft has repeatedly led to disastrous results. Too often, system safety is considered late in the design process, after much of the design is set. This thesis presents an iterative safety-driven system engineering process to address this problem. The process integrates safety into the design process, ensuring that safety is designed into the system, rather than added on. The techniques used in this process are: I) Intent Specifications, a framework for organizing system development and operational information in a hierarchical structure; 2) the System-Theoretic Accident Modeling and Processes (STAMP) model of accident causation, a framework upon which to base powerful safety engineering techniques; 3) STAMP-based Hazard Analysis (STPA) a novel hazard analysis technique; and 4) SpecTRM-Requirements Language (SpecTRM-RL), a formal modeling language. Intent Specification is used to document the design with complete traceability from system goals, requirements, and constraints to the operational design and software code. The STAMP framework is used to apply concepts from control theory to system engineering. STPA is used to identify hazards and eliminate them or mitigate their effects to ensure a safe system design. Finally, SpecTRM-RL is used to create the blackbox behavior models. An example of this process applied to an outer moon exploration mission is presented (in the form of an intent specification) and discussed. The specification focuses on the design of the control system and functionality of the scientific instruments, while also including a high-level design of the entire spacecraft. The application of the process described in this thesis demonstrates that design decisions are safety-driven, and that the results of the hazard analysis are integrated into all aspects of the design.by Margaret Virginia Stringfellow.S.M

Evolution of iron core white dwarfs

Recent measurements made by Hipparcos (Provencal et al. 1998) present observational evidence supporting the existence of some white dwarf (WD) stars with iron - rich, core composition. In this connection, the present paper is aimed at exploring the structure and evolution of iron - core WDs by means of a detailed and updated evolutionary code. In particular, we examine the evolution of the central conditions, neutrino luminosity, surface gravity, crystallization, internal luminosity profiles and ages. We find that the evolution of iron - rich WDs is markedly different from that of their carbon - oxygen counterparts. In particular, cooling is strongly accelerated as compared with the standard case. Thus, if iron WDs were very numerous, some of them would have had time enough to evolve at lower luminosities than that corresponding to the fall - off in the observed WD luminosity function.Comment: 8 pages, 21 figures.

Charged Condensate and Helium Dwarf Stars

White dwarf stars composed of carbon, oxygen or heavier elements are expected to crystallize as they cool down below certain temperatures. Yet, simple arguments suggest that the helium white dwarf cores may not solidify, mostly because of zero-point oscillations of the helium ions that would dissolve the crystalline structure. We argue that the interior of the helium dwarfs may instead form a macroscopic quantum state in which the charged helium-4 nuclei are in a Bose-Einstein condensate, while the relativistic electrons form a neutralizing degenerate Fermi liquid. We discuss the electric charge screening, and the spectrum of this substance, showing that the bosonic long-wavelength fluctuations exhibit a mass gap. Hence, there is a suppression at low temperatures of the boson contribution to the specific heat -- the latter being dominated by the specific heat of the electrons near the Fermi surface. This state of matter may have observational signatures.Comment: 10 pages; v2: to appear in JCAP, brief comments and section titles added, typos correcte

Promoting Faculty Scholarship Through the University Author Recognition Bibliography at Boise State University

One of the most important contributions by any university is its faculty members\u27 scholarship. Providing an interface to view the full scope of an institution\u27s academic accomplishments is vital for promoting both the scholarship and the university at large. Because of their unique information skills and services, librarians can facilitate the discovery of this scholarship on behalf of their institutions. This article explores how Albertsons Library at Boise State University utilizes an institutional repository to produce a faculty publication bibliography. Processes for collecting academic scholarship and organizing the citations within a repository structure are also discussed. Library staff found that this approach not only reduced redundancy and increased the usability of researcher publication data, it also increased the profile and value of the institutional repository
