Análise energética, ambiental, e econômica de biodigestores de circulação interna e concentradores de vinhaça para geração de eletricidade, fertilizantes e créditos de carbono em diferentes cenários econômicos / Energy analysis, environmental, and economic issues of internal circulation bio-digesters and vinasse concentrators for electricity generation, fertilizer and carbon credit in different economic scenarios

Geraldo José Ferraresi de Araujo 11 July 2017 (has links)
A vinhaça é um dos resíduos da produção de etanol, considerada de elevada capacidade poluidora. Estima-se que para cada litro de etanol produzido, produz-se entre 10 até 15 litros de vinhaça. Porém, este mesmo subproduto pode ser utilizado para geração de eletricidade, fertilizantes, biogás e obtenção de créditos de carbono a partir de biodigestores e concentradores. Logo, a vinhaça pode vir a contribuir para um incremento na geração de energia elétrica e de outros produtos para fomento de renda para o setor sucroenergético e resolver o problema ambiental no que se refere ao descarte in natura. Ante o exposto, justifica-se um estudo sobre a utilização da vinhaça, norteada pela problemática: qual a viabilidade econômica, ambiental e energética da utilização do biodigestor IC, concentrador de vinhaça e o conjugado de ambos? O objetivo geral foi analisar a viabilidade energética, ambiental e econômica da utilização de vinhaça em concentradores, biodigestores IC e em ambos para geração de eletricidade, fertilizantes e créditos de carbono. Para responder à pergunta, a metodologia utilizada na pesquisa foi a análise de viabilidade econômica, aonde foi calculado o VPL, TIR, payback e o payback descontado. Sendo qual foi calculado o consumo anual de Diesel no transporte de vinhaça biodigerida e concentrada, balanço de energia no consumo de Diesel e gerada pelo biogás por ano, balanço de geração e consumo de eletricidade e equivalente populacional de geração de eletricidade de vinhaça e, por fim, a análise ambiental, aonde foi calculado o equivalente populacional de vinhaça biodigerida e concentrada, balanço de emissão e mitigação de NOx, SOx e CO2 eq. pelo concentrador, transporte de vinhaça concentrada, ambas as três análises para uma faixa de produção de etanol de 500 até 4.000 m3/dia, como também para estados brasileiros produtores desse combustível. Como resultado pode-se constatar que os fertilizantes têm importância na viabilidade econômica dos biodigestores IC e concentradores de vinhaça, em cenários sem isenções tributárias e taxa mínima de atratividade 15% a.a. A eletricidade por si só terá viabilidade em cenário com baixa taxa mínima de atratividade de 11% e isenções fiscais. No que se refere a análise energética, destacam-se os resultados do biodigestor IC nas dimensões equivalente populacional e balanço de geração e consumo de eletricidade e na análise ambiental destaca-se o conjugado biodigestor IC e concentrador para as dimensões equivalente populacional e dióxido de carbono equivalentes emitidos e mitigados. Pode-se constatar a partir dos resultados alcançados e da revisão bibliográfica realizada os seguintes cenários desfavoráveis em potêncial para reutilização de vinhaça: baixo preço do MWh tanto no ACR quanto no ACL, incipiência no mercado de eletricidade, elevado investimento em transmissão, ausência de políticas públicas de incentivo a utilização de matéria orgânica proveniente da agropecuárias, ausência de políticas públicas de incentivo a utilização de energias renováveis, experiências não exitosas pelas usinas de utilização de vinhaça para produção de biogás, biodigestores em processo de consolidação tecnológica, incapacidade de financiamento do setor sucroenergético, preço dos concentradores de vinhaça, omissão legislativa referente ao descarte de vinhaça e descapitalização das usinas sucroenergeticas. / Vinasse is one of the residues from the production of ethanol, considered polluting high capacity. It is estimated that for every liter of ethanol produced, produces between 10 to 15 liters of vinasse. However, this same byproduct can be used for generating electricity, fertilisers, biogas and obtaining carbon credits from bio-digesters and concentrators. Soon, vinasse might contribute to an increase in the generation of electricity and other products to promote income for the sugar-energy sector and solve the environmental problem as regards disposal in natura. Against the above, if a study on the use of vinasse, guided by the problem: what is the economic viability, environmental and energy use of the biodigestor, vinasse concentrator and the conjunction of both? The overall objective was to analyze the energy, environmental and economic feasibility of the use of vinasse in hubs, biodigestors IC and in both for electricity generation, fertilizer and carbon credits. To answer, the methodology used in the research was the economic feasibility analysis, where it was calculated the NPV, IRR, payback and discounted payback. Being what was calculated the annual Diesel consumption of biodigerida and concentrated vinasse, energy balance in the consumption of Diesel and biogas generated per year, generation and balance electricity consumption and electricity generation population equivalent of vinasse and, finally, the environmental analysis, where it was calculated the population equivalent of biodigerida and concentrated vinasse emission and mitigation balance of NOx, SOx and CO2 eq. by concentrator, concentrated vinasse transport, both three analysis for a range of ethanol production from 500 to 4,000 m3/day, as well as to the Brazilian States that fuel producers. As a result one can note that fertilizers have importance in the economic viability of bio-digesters IC and vinasse concentrators, in scenarios without tax exemptions and minimum rate of 15% p.a. attractiveness The electricity itself will have viability in scenario with lower minimum rate of 11% attractiveness and tax exemptions. With regard to energy analysis, include the results of the biodigestor IC equivalent dimensions of population and balance of generation and electricity consumption and environmental analysis is the conjugate biodigestor IC and concentrator for the dimensions and equivalent carbon dioxide equivalent emitted and mitigated. You can see from the results achieved and the literature review carried out the following unfavourable scenarios on potential for reuse of vinasse: low price of MWh in both the ACR and the ACL, the effects on the market of electricity, high investment in transmission, absence of public policies to encourage the use of organic matter from the cattle-breeding, absence of public policies to encourage the use of renewable energy , not successful experiences through the use of vinasse plants for production of biogas, biodigesters consolidation technology, inability to finance the sugar ethanol sector, price of vinasse concentrators, legislative omission concerning the discharge of vinasse and decapitalization of sucroenergeticas plants.

物聯網少量多樣趨勢之因應策略 -以台灣IC設計公司為例 / Strategy to cope with the low-volume, mass customization trend of Internet of things – a case study on one Taiwan IC design company

謝鴻儒, Shieh, Horng-Ru Unknown Date (has links)
IC設計公司的間接成本高,須追求規模經濟,但對物聯網這種少量多樣的應用又有厚望。因此多會謹慎投入,怕投入如流水,又怕咬不到餅。 面對整體龐大的物聯網產業,歐美大廠運用優勢,嘗試建立特有的生態圈將各方納入。案例IC設計公司的規模很難和歐美大廠對作,但也有其優勢,不過原規模經濟的商業模式不再適用。 IC複雜使其位居重要位置,而案例IC設計公司擁有許多優秀工程人才,再加上成熟產品線廣,且和物聯網關聯,都是優勢資源。但做的是B2B生意,接觸不到終端市場,而新IC開發時間長,導致對終端需求掌握度低,且現有工程師數量是無法支援有多樣需求的微型物聯網業者,這些就是劣勢資源。 如案例IC設計公司將微型物聯網業者及獨立工作者拉到平台上,提供工作者自主工作機會,同時滿足物聯網業者不足的支援人力。案例IC設計公司須貢獻包含工作者的訓練與認證、協助物聯網業者找到符合的工作者、設計專案流程管理機制同時確保工作者收得到價金。如此解決了對微型物聯網業者支援不夠的問題,還可藉由平台獲取最真確的需求資訊,又解決另一困境。 三方都有得且無太多風險,可行性確認。用波特的五力分析,案例IC設計公司導入新商業模式有相當優勢,早投入更可建立先行者優勢。

Die Expression muskarinerger und purinerger Rezeptoren in Urothelzellen und suburothelialen Myofibroblasten im Rahmen des Bladder Pain Syndrom/Interstitielle Zystitis (BPS/IC)

Feige, Thomas 29 November 2016 (has links)
Die Dysregulation von Neurotransmittersystemen spielt eine wesentliche Rolle für die Pathophysiologie des Bladder Pain Syndrom/Interstitielle Zystitis (BPS/IC). Diese Arbeit beschäftigt sich daher mit der veränderten Expression muskarinerger (M2, M3) und purinerger (P2X1, P2X2, P2X3) Rezeptoren auf Urothelzellen und suburothelialen Myofibroblasten der Harnblasenwand im Rahmen BPS/IC. Dazu wurde eine Gruppe von Patientinnen mit Verdacht auf BPS/IC (n=17) einer Kontrollgruppe (n=7) gegenübergestellt. Die Gewebeproben der Patientengruppe sind im Zuge der Basisdiagnostik (transurethrales Harnblasenmapping) bei klinischem Verdacht auf das Vorliegen eines BPS/IC entnommen worden. Das Gewebe der Kontrollgruppe entstammt makroskopisch unauffälligen Bereichen von Harnblasen, welche im Rahmen einer radikalen Zystektomie oder einer lateral erweiterten endopelvinen Resektion (LEER-OP) entnommen worden sind. Die semi-quantitative Analyse der Rezeptorexpression erfolgte mittels indirekter Immunfluoreszenz, die Auswertung erfolgte mittels konfokaler Laserscanningmikroskopie. Die Ergebnisse der Patientengruppe wurden mit denen der Kontrollgruppe verglichen. Im Rahmen dessen wurde auch ein individuelles Rezeptorprofil für jeden Patienten erstellt. Es zeigte sich eine Hochregulation von M2R, M3R und P2X1R auf Urothelzellen sowie eine Hochregulation von M2R, M3R, P2X1R und P2X2R auf suburothelialen Myofibroblasten in der BPS/IC-Gruppe im Vergleich zur Kontrollgruppe. Des Weiteren zeigten sich individuelle Unterschiede in den Rezeptorprofilen der Patienten. Die Ergebnisse werden vor dem Hintergrund einer möglichen Beteiligung der Regulation von muskarinergen und purinergen Rezeptoren an der Pathophysiologie des BPS/IC diskutiert.

Assessing Knowledge Management Values by Using Intellectual Capital to Measure Organizational Performance

Nguyen, Thuan L. 01 January 2016 (has links)
Measuring knowledge management performance was one of, if not the most challenging knowledge management activities. This study suggested using intellectual capital as a proxy for knowledge management performance in evaluating its impact on organizational performance. The Value Added Intellectual Coefficient model was employed to measure intellectual capital. Although being used widely in research, the model had its limitations. Also, for intellectual capital measurement, there was a lack of guidelines supported by empirical evidence or best practices. The present study aimed to test the classic and a modified version of this model, and based on the results, shed light on whether the classic version was good enough or the modified one should be highly recommended. The financial fundamental and market data of 425 randomly selected publicly listed firms were collected, and the structural equation modeling technique was employed to test the models. Chi-square difference test was performed to determine whether there was a statistically significant difference between these two models. The results of the tests indicated that the difference between them was insignificant. Therefore, it was concluded that the classic model is adequate, and it can be used effectively to measure intellectual capital. Adding two new efficiency elements – research and development efficiency and relational capital efficiency – in the model did not provide any significant benefit.

Incitament bakom rapportering av intellektuellt kapital : En kategoribaserad analys av årsredovisningar från åtta IT-företag / Incentives behind Intellectual Capital disclosure : A category based analysis of annual reports from eight IT companies

Eklund, Johan, Larsson, Elinor January 2014 (has links)
Syftet med denna studie är uppdelat i två aspekter. För det första avser vi bidra till kunskapsutveckling genom att observera och presentera vilka incitament som kan finnas bakom kommunicerande av intellektuellt kapital (IK) utifrån IT-företags rapportering av IK genom årsredovisningen. För det andra avser vi att genom vår studie ge ett metodbidrag till forskningen på IK-området genom att visa hur kategorisering med hjälp av ett flerdimensionellt analysverktyg kan användas, tillsammans med olika teoretiska perspektiv, för att analysera hur incitament för rapportering av IK reflekteras i IT-företags årsredovisningar.Studien har utförts genom att empiriskt material från årsredovisningar har kategoriserats utifrån en nyskapad modell bestående av fyra huvudkategorier med vardera fyra underkategorier. Modellen är starkt influerad av Sveiby (1997) och Meritum Project (2002) men utgörs totalt sett av en syntes av ett antal olika modeller och teorier från forskare inom IK-området, med vissa externa influenser. Det kategoriserade empiriska materialet har sedan analyserats utifrån fyra teoretiska analysperspektiv. Dessa fyra perspektiv är intressentteorin, legitimitetsteorin, signalteorin och IC disclosure motivations. Studien är utformad som en kvalitativ innehållsanalys och empirisk data i studien utgörs av årsredovisningar från åtta bolag i IT-branschen listade på marknadsplatsen Nasdaq OMX Nordic Stockholm (Stockholmsbörsen).Resultatet av studien visar att det kan finnas olika incitament för företag att kommunicera sitt IK genom årsredovisningen beroende på vilken teori som används som analysperspektiv. När det gäller intressentteorin kan företagens incitament i stor utsträckning ta sin utgångspunkt i intresset att kunna bedöma företagets risknivå. Utifrån legitimitetsteorin skulle ett incitament bakom rapportering kunna vara att visa att företaget använder sina resurser på ett effektivt och ansvarsfullt sätt. Signalteorin kan erbjuda en möjlighet för företagen att skicka positiva signaler till marknaden även om önskan att inte lämna för mycket information till konkurrenter kan sätta vissa begränsningar. Utifrån modellen för IC disclosure motivations förefaller företagen ha incitament att använda kommunikationen av IK genom årsredovisningen som ett medel för att bland annat stärka sina varumärkens position bland sina intressenter. / Program: Civilekonomprogrammet

全球IC設計產業生產力與效率分析

楊夏青 Unknown Date (has links)
台灣的IC設計產業總產值全球僅次於美國,自從九零年代中期成為我國極受矚目的產業。因此本研究所探討的主題為全球IC設計產業的生產效率分析,以2003年全球營收前卅大IC設計廠商為樣本。透過資料包絡法(Data Envelopment Analysis,DEA),針對不同地區與個別廠商進行2000年至2002年的效率分析,最後進行Tobit迴歸分析,求得影響廠商生產績效的因子,提供本國廠商改善效率的參考,實證結果為: 1.DEA跨國比較的結果顯示,在2000年至2002年整體技術效率值最高的地區為美國,在2000年與2001年為台灣整體技術效率值僅次於美國,但在2002年卻落居第三。觀察個別廠商績效,Qualcomm、MediaTek、Marvell、ICS、Lattice、Pmc-Sierra與DSP Group等廠商績效最好,其整體技術效率值為1。 2.Malmquist生產力指數(MPI)跨國比較的結果顯示,臺、美、加三國總要素生產力均呈現退步的情形,2001至2002年,臺、加總要素生產力呈現進步,美國呈現退步。就個別廠商而言,在2000年至2001年間有四家廠商總要素生產力進步,在2001至2002年年則有十五家廠商總要素生產力呈現進步的狀況。 3.Tobit迴歸分析的結論為:存貨週轉率inventory turnover對整體技術效率有顯著的正向影響;負債比率與平均收帳期間均對整體技術效率有顯著的負面影響。研發費用率、經營年限與整體技術效率呈現正向關係,至於每人配備率則呈現負相關。 / The total output value of Taiwanese IC design industry is the globally second following United States. It had become the domestic gazed industry since mid 90s. Therefore, this research studies the production efficiency of global IC design industry and chooses the firms which sales globally ranked top 30 as samples. Through DEA, this thesis analyzes the efficiency focused on different regions and individual firms from 2000 to 2002. And finally, the Tobit regression model is proposed to find out the factors that influenced performances of firms and it could be reference for the domestic firms to improve their production efficiency and productivity. The results display: 1. By comparison with regions, the DEA results display that U.S.A. United States has the highest overall technical efficiency(TE) value during 2000 to 2002. Taiwan ranked behind U.S. both in 2000 and 2001 but dropped to the 3rd position in 2003. Observing performances of individual firms, Qualcomm, MediaTek, Marvell, ICS, Lattice, Pmc-Sierra and DSP Group performed as the best and their efficiency value is 1. 2. By comparison with regions, Malmquist Productivity Index(MPI) results display that the U.S.., Taiwan and Canada showed their Total Factors Productivity (TFP) to degenerate from 2000 to 2001. However, Taiwan and Canada showed their progressive TFP, progress in TFP but U.S.A. had a regressive TFP from 2001 to 2002. For one individual firm, there were only 4 firms’ TFP being aggressive from 2000 to 2001 and there are 15 firms’ TFP aggressive from 2001 to 2002. 3. The result from running Tobit regression models display that Inventory Turnover has significant positive effect to TE; Debate Ratio and Average Collection Period have significant negative effect to TE; R&D Ratio and Incorporated Period have direct relation with TFE and Equipment Per Employee has negative relation with TE.
