Perenniporiella chaquenia sp. nov. is described from Argentina. New records of P. pendula and P. micropora are discussed. A key to Perenniporiella species is presented. Preliminary phylogenetic relationships of Perenniporiella are inferred from parsimony and Bayesian analysis of a combined set of DNA sequence data (nuclear ribosomal partial LSU and ITS). It demonstrated that Perenniporiella forms a well resolved monophyletic clade distantly related to Perenniporia s.s. It also clearly showed that within Perenniporia as usually conceived other morphologically homogeneous group of taxa, such as the P. ochroleuca or P. vicina alliances, form well resolved clades, which could be recognized as distinct genera. The differentiation of the hyphal system and the basidiospores morphology are outlined as critical features for the definition of genera in the Perenniporia complex. [less ▲]

This is the first study to report on concentrations of perfluorinated organochemicals (FOCs) in marine mammals stranded along the southern North Sea coast in relation to stable nitrogen and carbon isotope ratios (delta(15)N and delta(13)C). The presence of FOCs in top predators such as marine mammals would indicate a potential biomagnification of these compounds and their widespread occurrence. Liver and kidney tissues of nine marine mammal species have been sampled. Among all the measured FOCs compounds, PFOS (perfluorooctane sulfonate) was predominant in terms of concentration. The highest PFOS concentrations were found in the liver of harbor seal compared to white-beaked dolphin, harbor porpoise, gray seal, sperm whale, white-sided dolphin, striped dolphin, fin whale, and hooded seal. PFOS concentrations differed significantly between sexes and age classes in harbor porpoises. Stable isotope measurements (delta(13)C and delta(15)N) were used in this study to describe the behavior of contaminants in food webs. We found a significant (p < 0.05) linear relationship between PFOS concentrations in livers of harbor porpoises and both Muscle delta(13)C and delta(15)N measurements. Harbor and gray seals and white-beaked dolphin, which displayed the highest trophic position, contained the highest PFOS levels, while offshore feeders such as sperm whales,fin whales, striped dolphin, and white-sided dolphin showed lower PFOS concentrations than inshore species.

Over the last decades little work has been conducted on the environmental behaviour and effects of perfluorinated organochemicals (FOCs). These chemicals are commonly used as solvents, surfactants, cosmetics and are applied in fire foam extinguishers. Recent findings have shown that FOCs (with perfluorooctane sulfonic acid - PFOS - as the most important representative) are detected in organisms living in industrialized as well as in remote areas. The fact that PFOS is hardly biodegradable, clearly accumulates in the liver and blood of top predators and the fact that little information is available on the toxic properties of PFOS, makes this chemical an environmental pollutant of primary concern. In the present study we measured PFOS concentrations in seven marine mammals stranded on the Belgian, French and Dutch North Sea coast between 1994 and 2000. PFOS concentrations were measured in liver and kidney tissue using combined liquid chromatography-mass spectrometry (LC-MS/MS). Detectable PFOS concentrations (up to 820.60 ng/g) were found in harbour porpoises, white-beaked, white-sided and striped dolphins, sperm whales and harbour seals. In fin whale and hooded seal concentrations were below the detection limit of 10 ng/g. PFOS levels in female porpoise livers were significant higher than those in males. The present results show clearly the difference in accumulation pattern of PFOS compared to that of persistent organochlorine chemicals. In order to evaluate the interspecies differences, we developed PFOS-trophic level relationships based on stable nitrogen and carbon isotope ratios. Animals that display the highest trophic positions (highest d15N) have the highest PFOS levels. The different feeding ecology of these species (inshore versus offshore) also seems to contribute to differences in PFOS concentrations. Next to the presentation of PFOS concentrations in marine mammals of the North Sea, the possible toxicological effects of perfluorinated compounds are discussed. [less ▲]

Recent interest in small-scale solar thermal combined heat and power (CHP) power systems has coincided with demand growth for distributed electricity supplies in areas poorly served by centralized power stations. One potential technical approach to meeting this demand is the parabolic trough solar thermal collector coupled with an organic Rankine cycle (ORC) heat engine. The paper describes the design of a solar organic Rankine cycle being installed in Lesotho for rural electrification purpose. The system consists of parabolic though collectors, a storages tank, and a small-scale ORC engine using scroll expanders. A model of each component is developed taking into account the main physical and mechanical phenomena occurring in the cycle and based on experimental data for the main key components. The model allows sizing the different components of the cycle and evaluates the performance of the system. Different working fluids are compared, and two different expansion machine configurations are simulated (single and double stage). [less ▲]

We re-examine the performance of Commodity Trading Advisors (CTAs) over the January 1995 to October 2008 period. We compare abnormal performance based on a number of alternative existing models, as well as a category-specific model introducing asset-, option-, and moments-based factors. Taking more factors into account significantly raises the explanatory power, and 9 out of 12 CTA categories significantly outperform the market. We find that numerous CTAs show persistence over a horizon of at least three months and they are also more likely to be persistent over a longer period. Yet, most of the persistence fades away upon the “acid test” of considering only the top and bottom quartiles of CTAs. [less ▲]

A 5 kW SOFC (Solid Oxyde Fuel Cell) performance will be detailed. This kind of cogeneration, a typical one for residential application, will be able to replace actual boiler in most of applications. The combination of high temperature hot water output combined with grid-tie electricity delivery will progressively replace actual systems. This will help to significantly reduce GHG (green house gas) emission to about 20% , even compared to actual emissions, based on high performance boiler and electricity produced by high efficiency combined cycle. The particular benefit of SOFC compared to other technologies of fuel cell is the high temperature from one side (giving access to appropriate hot water for heating purposes) and the very exciting high electricity efficiency which is over 40%, together with a global efficiency measured over 80%. This paper is analysing an existing 5 kW unit SOFC which has shown such high level efficiencies [less ▲]

In the context of the solar air-conditioning systems analysis, it is crucial to assess system performance by experimentations in real-time conditions. In this way, it is possible to calculate the energy savings to minimize environmental impact and CO2 production induced by the operation of such a system in buildings operation. It is proposed to measure the thermal behaviour and the energy performance of a smallscale solar air-conditioning system used to cool a laboratory building in the South of Belgium. The experimental system is recently installed and fully instrumented for both thermal and electrical COP computation. Results of two months operation and data analysis are presented in this work.
