Analysis of efficiency and rationality in a sugar-alcohol mill using hyperboloid a-load and potency

Brazil is the world's largest producer of sugar cane and which in the state of São Paulo concentrate the greatest amount of sugar cane field of the country. The sugar-alcohol sector has the capacity to produce sufficient thermal and electrical energy to be used in their process of production and commercialize of surplus in electricity distribution network. Therefore it is necessary to evaluate the energy efficiency and rationality within the mill. Accordingly this research proposed analyze the sugar-alcohol mill's sectors globally and individually, located in the west center of the São Paulo state, using the valuation methodology employed by the Agência Nacional de Energia Elétrica (ANEEL) in the industries that do not have systems of cogeneration. In this analysis, the hyperboloids of load and potency were applied based on the indexes of potency factor and load factor that allow estimate the efficiency and rationality. © 2013 IEEE.

Luminescence quantum efficiency at 1.5 μm of Er3+-doped tellurite glass determined by thermal lens spectroscopy

Erbium doped tellurite glasses (TeO2 + Li2O + TiO2) were prepared by conventional melt-quenching method to study the influence of the Er3+ concentration on the luminescence quantum efficiency (η) at 1.5 μm. Absorption and luminescence data were used to characterize the samples, and the η parameter was measured using the well-known thermal lens spectroscopy. For low Er3+ concentration, the measured values are around 76%, and the concentration behavior of η shows Er-Er and Er-OH- interactions, which agreed with the measured lifetime values. © 2013 Elsevier B.V.

Measures to improve energy efficiency in shipping

This paper provides an overview of several parameters that would improve the fuel efficiency of shipping. Calculations are carried out from a Latin American perspective, and illustrate the emmissions to air and the fuel consumed by different transport modes.

Energy efficiency in freight transport by road

This issue of the FAL Bulletin addresses energy efficiency and its challenges in terms of freight transport by road. To this end, different national plans for energy efficiency in transport were reviewed, for both developed countries and for Latin America.

Competitiveness and efficiency in land transport

One of the consequences of the opening of the worlds economies - an integral part of globalization - is increased focus on the efficiency and costs of transport services (on which competitiveness is largely dependent). Countries with inefficient and costly transport services lose out, in terms of economic activity and income, to those with more appropriate transport services. The issue is particularly important in Latin America, where exports mainly consist of bulk consignments of products with comparatively low value/quantity ratios and transport costs are a major determining factor of c.i.f. prices.The determination of competitiveness indices in the long term, however, also needs to include the costs of pollution, congestion and accidents, in addition to the transport costs usually considered as part of the price of freight. Competitiveness, efficiency and the global costs of transport were the main subjects of an international seminar organized in conjunction with the Chilean Institute of Engineers and held on 9 and 10 September 2004 at the Headquarters of the Economic Commission for Latin America and the Caribbean (ECLAC).
