Biodiésel a partir de algas, ¿el combustible ideal para la Antártica?
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Cid, P.
Durante la campaña antártica 2008 de la Universidad de Magallanes, el equipo liderado por el autor efectuó una evaluación de las necesidades energéticas de la base Bernardo O’Higgins (63º19’15” S, 57º53’55” O) y realizó exploraciones en los alrededores con el objetivo de identificar materias primas adecuadas para la elaboración in situ del combustible verde. En esta oportunidad, se encontraron algunas variedades de algas y microalgas que fueron consideradas con buen potencial para la producción de biodiésel.

Autores: Noone, K.J.; Öström, E.; Ferek, R.J.; Garrett, T.; Hobbs, P.V.; Johnson, D.W.; Taylor, J.P.; Russell, L.M.; Flagan, R.C.; Seinfeld, J.H.; O'Dowd, C.D.; Smith, M.H.; Durkee, P.A.; Nielsen, K.; Hudson, J.G.; Pockalny, R.A.; De Bock, L.; Van Grieken, R.E.; Gasparovic, R.F.; Brooks, I.
The effects of anthropogenic particulate emissions from ships on the radiative, microphysical, and chemical properties of m(oderately polluted marine stratiform clouds are examined. A case study of two ships in the same air mass is presented where one of the vessels caused a discernible ship track while the other did not. &lt;i&gt;In situ&lt;/i&gt; measurements of cloud droplet size distributions, liquid water content, and cloud radiative properties, as well as aerosol size distributions (outside cloud, interstitial, and cloud droplet residual particles) and aerosol chemistry, are presented. These are related to measurements of cloud radiative properties. The differences between the aerosol in the two ship plumes are discussed; these indicate that...

Household Energy Demand and the Equity and Efficiency Aspects of Subsidy Reform in Indonesia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Olivia,   Susan; Gibson,   John.
The proper design of price interventions requires consideration of equity and efficiency effects. In this paper, budget survey data from 29,000 Indonesian households are used to estimate a demand system for five energy sources, which is identified by the spatial variation in unit values (expenditures divided by quantities). We correct for the various quality and measurement error biases that result when unit values are used as proxies for market prices. The price elasticities are combined with tax and subsidy rates to calculate the marginal social cost of price changes for each item. The results suggest that even at high levels of inequality aversion there is a strong case for reducing the large subsidies on gasoline and kerosene, supporting the reforms...

La política de precios de los combustibles y la distribución del ingreso en el Perú: 1985-1990
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pasco-Font Quevedo,   Alberto; Briceno Lira,   Arturo.
Este documento evalúa los efectos sobre la distribución del ingreso de la política de precios e impuestos a los combustibles aplicada entre julio de 1985 y julio de 1990, período en el cual el gobierno manipuló activamente dichos precios e impuestos para combatir la inflación y mejorar la distribución del ingreso.
