Exploring the Utilization of Lesser-Known Species for Furniture Production—A Case Study in the Western Region, Ghana  [PDF]
Job Ewudzie, John Gemadzie, Harold Adjarko
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104916
Abstract:
Increased demand for traditional timber species has led to the depletion of large areas of Ghana’s forest cover. Sustainable forest management requires that measures are put in place to minimize forest depletion through the utili-zation of lesser-known species, reforestation, setting margins for annual al-lowable cut, banning export of round logs, conservation of biological diversity and promotion of efficient wood-based industry. The study aimed at exploring public perception on the use of lesser-known species for making furniture to save our dwindling forest. The research methods adopted were purposive and random sampling. It is purposive because the research was targeted at furniture shops and furniture showrooms and random sampling was used to make the selection. A questionnaire was developed to acquire data for the study from experienced people in the timber industry as well as the general public. Specifically, 450 people were contacted to fill the questionnaire from 15 constituencies out of 29 in the Western Region. Personal interviews were also conducted. The research revealed that most Ghanaians prefer traditional species to the lesser-known ones. Greater part of the population prefers species like Odum, Danta, Dahoma, and Denyan etc. For roofing whiles Cedar, mahogany, Makore, Walnut, and Avodirie are used for furniture. The perception is that when the traditional species are used for either roofing or furniture they last longer. Some challenges with the use of lesser-known species are lack of ready market for products may from lesser known species, and lack of requisite machines to work with some of the lesser-known species etc. The study concluded that there is the need here in Ghana to promote the utilization of lesser known species; since majority of furniture manufacturers have little knowledge about their usage in the industry.
GC- and AT-rich chromatin domains differ in conformation and histone modification status and are differentially modulated by Rpd3p

Abstract: We have compared GC- and AT-rich isochores of yeast with respect to chromatin conformation, histone modification status and transcription. Using 3C analysis we show that, along chromosome III, GC-rich isochores have a chromatin structure that is characterized by lower chromatin interaction frequencies compared to AT-rich isochores, which may point to a more extended chromatin conformation. In addition, we find that throughout the genome, GC-rich and AT-rich genes display distinct levels of histone modifications. Interestingly, elimination of the histone deacetylase Rpd3p differentially affects conformation of GC- and AT-rich domains. Further, deletion of RPD3 activates expression of GC-rich genes more strongly than AT-rich genes. Analyses of effects of the histone deacetylase inhibitor trichostatin A, global patterns of Rpd3p binding and effects of deletion of RPD3 on histone H4 acetylation confirmed that conformation and activity of GC-rich chromatin are more sensitive to Rpd3p-mediated deacetylation than AT-rich chromatin.We find that GC-rich and AT-rich chromatin domains display distinct chromatin conformations and are marked by distinct patterns of histone modifications. We identified the histone deacetylase Rpd3p as an attenuator of these base composition-dependent differences in chromatin status. We propose that GC-rich chromatin domains tend to occur in a more active conformation and that Rpd3p activity represses this propensity throughout the genome.Chromosomes are characterized by regions that differ in base composition [1,2]. These so-called isochores correspond to functionally distinct domains that are cytologically visible as R- and G-bands [2-4]. Functional differences between the two types of regions include higher and lower levels of transcription and meiotic recombination and earlier and later firing of replication origins.Isochores in the yeast Saccharomyces cerevisiae range in size from 5-90 kb [5-9]. Clear evidence that isochores are correlated wi

Revista ACB , 2008,
Abstract: [Portuguese] Ensaio de discuss o teórica e conceitual da informa o, objeto de estudo da Ciência da Informa o na sua abordagem cognitivista, enfatizando a sua rela o com a representa o do conhecimento, bem como sua característica de interdisciplinaridade. Os conceitos da área e seus atributos s o analisados segundo os teóricos epistemológicos da Ciência da Informa o, sobretudo Saracevic que coloca as ciências cognitiva e da computa o como dois de seus pilares. Os outros s o a biblioteconomia e a comunica o. A interdisciplinaridade apresentada contribui para a análise dos processos cognitivos envolvidos no comportamento dos produtores e dos usuários de sistemas de tratamento da informa o no sentido de compreender a informa o, como ela é percebida, recepcionada e comunicada.[English] The present is an essay on the conceptual and theoretical discussion of information, which is the study object of Information Science in its cognivitist approach; it emphasizes its relation with knowledge representation as well as its interdisciplinarity. Concepts and their attributes are analyzed according to the epistemologic theorists of Information Science, especially Saracevic, who establishes cognitive and computing sciences as two of its pillars. The others are librarianship and communication. The interdisciplinarity presented herein contributes to the analysis of the cognitive processes involved in the behavior of producers and users of information treatment systems towards understanding information, how it is perceived, received, and communicated.

Boletin del Grupo Espa?ol del Carbon , 2012,
Abstract: Diffusional limitations in carbon gel-supportedcatalysts are often encountered despite their openstructure. However, the analysis of mass transportis rarely taken into account in studies dealing withcatalyst preparation and test using thesenanostructured carbons as supports. Any catalyticsystem should be first subject to mass transportanalysis before any conclusion can be drawn aboutrelationships between the physico-chemicalproperties and the measured activity of the catalyst.
Redes, atores e desenvolvimento rural: perspectivas na constru??o de uma abordagem relacional
Schmitt, Claudia Job;
Sociologias , 2011, DOI: 10.1590/S1517-45222011000200005
Abstract: the construction of a relational approach to the study of the complex social dynamics configuring the contemporary rural world stands, particularly after the 1980's, as a challenge for the social sciences. in this direction, different lines of interpretation incorporated the notion of network, as an analytical tool connecting actors, meanings, objects and practices, in the study of rural development processes. this article aims to explore some of these analytical frames of reference, identifying convergences and discontinuities among different perspectives.
The Decline of the Dollar: Implications for Nigeria's Foreign Reserves
Job Pristine Migap
International Journal of Economic Development Research and Investment , 2010,
Abstract: Nations rise and fall according to the trends of their economies. For it is the economic growth of a nation that confers on it, its status among the comity of Nations. Since the end of World War II, the American economy has led the world in terms of trade, manufacturing, innovation, finance etc. Hence the American state became the leading nation in the world and the dollar, the de-facto currency most sought after as a means of lubricating trade and storage of wealth. However, over the last decade there has been a gradual slow down in the American economy; growth has petered down and the status of the dollar among international currencies is on the decline. Will the dollar lost its dominant role in international transactions as a reserve currency? This paper notes that it will happen, albeit slowly. Hence, it purports to highlight the demerits of maintaining our external reserves in a single currency (Dollar).Drawing heavily from existing literature on external reserves management and exchange rate, It suggests that the monetary authorities should start a gradual divestment from purely dollar denominated securities to securities denominated in other currencies .Only the optimal level of reserves should be kept by the authorities while the excess should be used for infrastructural development, as well as institute A Sovereign Wealth Funds to manage the revenue from sales of crude oil for future generations; among others.
The Impact of Consumers’ Protection Laws and the Regulatory Schemes in Nigeria
Dennis Odigie,Job Odion
International Journal of Advanced Legal Studies and Governance , 2011,
Abstract: This Study was a review of the impact of Consumers’ Protection Laws and the Regulatory Schemes in Nigeria. The logical conclusion that readily flows from the context analysis of this study is that the Courts, relevant Consumer Protection Statutes and Regulatory Agencies have failed to offer the desired and much expected protection to the Consumer. Consequently, the Consumer is simply left unprotected and at the mercy of unconscionable manufacturers and pretentious traders. A model Consumer Protection Law that affords a remedy on the basis of defect in consumer goods, rather than resultant injury to the consumer among others is recommended.
