The Responses of Cytochrome Redox State and Energy Metabolism to Dehydration Support a Role for Cytoplasmic Viscosity in Desiccation Tolerance1

To characterize the depression of metabolism in anhydrobiotes, the redox state of cytochromes and energy metabolism were studied during dehydration of soaked cowpea (Vigna unguiculata) cotyledons and pollens of Typha latifolia and Impatiens glandulifera. Between water contents (WC) of 1.0 and 0.6 g H2O/g dry weight (g/g), viscosity as measured by electron spin resonance spectroscopy increased from 0.15 to 0.27 poise. This initial water loss was accompanied by a 50% decrease in respiration rates, whereas the adenylate energy charge remained constant at 0.8, and cytochrome c oxidase (COX) remained fully oxidized. From WC of 0.6 to 0.2 g/g, viscosity increased exponentially. The adenylate energy charge declined to 0.4 in seeds and 0.2 in pollen, whereas COX became progressively reduced. At WC of less than 0.2 g/g, COX remained fully reduced, whereas respiration ceased. When dried under N2, COX remained 63% reduced in cotyledons until WC was 0.7 g/g and was fully reduced at 0.2 g/g. During drying under pure O2, the pattern of COX reduction was similar to that of air-dried tissues, although the maximum reduction was 70% in dried tissues. Thus, at WC of less than 0.6 g/g, the reduction of COX probably originates from a decreased O2 availability as a result of the increased viscosity and impeded diffusion. We suggest that viscosity is a valuable parameter to characterize the relation between desiccation and decrease in metabolism. The implications for desiccation tolerance are discussed.

An econometric analysis of ETF and ETF futures in financial and energy markets using generated regressors

It is well known that that there is an intrinsic link between the financial and energy sectors, which can be analyzed through their spillover effects, which are measures of how the shocks to returns in different assets affect each other’s subsequent volatility in both spot and futures markets. Financial derivatives, which are not only highly representative of the underlying indices but can also be traded on both the spot and futures markets, include Exchange Traded Funds (ETFs), which is a tradable spot index whose aim is to replicate the return of an underlying benchmark index. When ETF futures are not available to examine spillover effects, “generated regressors” may be used to construct both Financial ETF futures and Energy ETF futures. The purpose of the paper is to investigate the covolatility spillovers within and across the US energy and financial sectors in both spot and futures markets, by using “generated regressors” and a multivariate conditional volatility model, namely Diagonal BEKK. The daily data used are from 1998/12/23 to 2016/4/22. The data set is analyzed in its entirety, and also subdivided into three subset time periods. The empirical results show there is a significant relationship between the Financial ETF and Energy ETF in the spot and futures markets. Therefore, financial and energy ETFs are suitable for constructing a financial portfolio from an optimal risk management perspective, and also for dynamic hedging purposes.

Recommendations for Soil and Water Conservation Programs

The United States Department of Agriculture employs soil and water conservation programs to assist with the sustainable use of natural resources in balance with economic vitality in rural America. This capstone project analyzed soil and water conservation programs to identify strengths, weaknesses, and methods to maximize environmental benefits. There are many requirements for participation in these programs which are difficult for most agricultural producers to comprehend. Research indicates in order to accomplish the goals of federal conservation programs and assist individuals, a method must be developed to effectively present information in a concise manner. This capstone project created a communicative measure, a template, to disseminate pertinent knowledge on soil and water conservation programs, thereby filling a void in existing literature.

The episcopal complex of Eio-El Tolmo de Minateda (Hellín, Albacete, Spain). Architecture and spatial organization. 7th to 8th centuries AD

The episcopal complex of Eio, located in El Tolmo de Minateda, was built between the end of the 6th century and the beginning of the 7th century, possibly as a political decision taken by the ecclesiastical authority in the capital of the Visigothic kingdom (Toletum). With the comprehensive study of the whole complex presented below (construction cycles, furniture, decoration and location of spaces), we can interpret the function of each space in the basilica and the domus episcopi, the liturgical and general movement routes, the existence of some hierarchical environments, and specify the chronological development of the buildings. After the Arab-Berber conquest of Hispania in the early 8th century, the whole complex will experience a series of transformations that will convert the religious and monumental public area into a private, residential and industrial Islamic quarter.

The New EU Climate and Energy Package: Passing the test? CEPS Commentary, 6 January 2014

On 22 January 2014, the European Commission is expected to publish the proposals for the 2030 Framework for Climate and Energy Policies, which will be discussed and possibly – or maybe, partly – agreed during the 20-21 March 2014 European Council. This is the first comprehensive review of the 2007-09 Climate and Energy Package, which resulted in the so-called ‘20-20-20’ targets by 2020. The principal intention is to define the EU’s climate change and energy policy framework for the next decade and beyond to give investors an adequate amount of predictability if not certainty. This Commentary argues, however, that the ‘2030 Framework’ is not just about predictability; it is also about making the proper adjustments based on the lessons learned and also in response to new issues that have emerged in the interim. The authors ask what the main lessons are and how they should influence the 2030 Framework. Or put differently, what are the conditions that the “2030 Framework” will need to meet in order to offer a viable package for discussion?

The 2030 framework on climate and energy - Getting Europe on the right track? EPC Commentary, 30 January 2014

Climate vs competitiveness? The European Commission published its proposal on the 2030 climate and energy framework on 22 January. Reflective of the current economic climate, it was accompanied by a report on energy prices and the Commission decided not to propose regulation on shale gas but to issue recommendations on environmental standards. The same day also saw the publication of a communication “For a European Industrial Renaissance”. Climate considerations no longer drive the agenda. The enthusiasm of 2007, when the “20/20/20” climate and energy targets were set for 2020, has diminished. The new reality has brought competitiveness to the top of the EU’s priority agenda.

Between energy security and energy market integration. Guidelines for the future development of the EU’s external energy policy in Europe’s neighbourhood. OSW Report, June 2011

For many years the European Union has been improving the efficient use of energy resources and yet the demand for energy in the EU continues to increase. When Europe belonged to one of the world’s key energy markets with relatively easy access to energy resources, growing energy needs were not seen as a source of concern. Today, however, as the competition for energy resources is intensifying and the global position of the EU energy market is being challenged by growing economies in the developing countries, above all China and India, the EU needs to adopt bold policies to guarantee the sustainable supply of energy. This report argues the EU needs to develop a fully-fledged external energy policy; i.e. a common, coherent, strategic approach that build bridges between the interests and needs of the EU integrated energy market on the one hand and supplier countries on the other. The EU’s external energy policy has two main objectives. The first one is to ensure a sustainable, stable and cost-effective energy supply. The second is to promote energy market integration and regulatory convergence with neighbouring countries (often but not always this supports the achievement of the first objective). However, in order to improve its effectiveness, the EU’s external energy policy needs to be seen in a broader economic and political context. Any progress in energy cooperation with third countries is contingent upon the EU’s general stance and offer to those countries.

EU climate and energy policy: hope for more and better climate policy integration? IES Policy Brief Issue 2014/02/January 2014

Summary. With discussions on-going in the EU on the climate and energy policy framework to 2030, it is timely to assess the reality of climate policy integration into EU energy policy. Such an analysis can lead to lessons for the legislative process for the 2030 package, and even for policies in other sectors and beyond 2030. Climate change is a complex, crosscutting, long-term and global problem. Policymakers acknowledge that integrating climate policy objectives into the elaboration and agreement of measures in other sectors represents one method for striving towards coherent policies that respond adequately to the climate change problem. This policy brief presents the results and policy recommendations from the project “climate policy integration into EU energy policy”.
