By precipitating a complex salt Ly(OS)(8) of the positively charged protein lysozyme and the anionic surfactant octyl sulfate OS-, one can generate a true ternary system: water-Ly(OS)(8)-NaOS. Using NMR diffusometry and U spectroscopy measurements the thermodynamic parameters of the association processes have been determined. The solubility product of the complex salt, K-s, is 10-(28) M-9.(1) On
The objective of this study has been to create an online system for condition monitoring and diagnosis of a combined heat and power plant in Sweden. The system in question consisted of artificial neural network models, representing each main component of the combined heat and power plant, connected to a graphical user interface. The artificial neural network models were integrated on a power gener
La chimie des otolithes de poissons sert a associer les poissons a des environnements specifiques. La chimie des otolithes peut aussi potentiellement servir d'outil dans la recherche phylogenetique, comme nous le demontrons ici chez les poissons salmonides et les taxons apparentes. Des cartes bidimensionnelles de la chimie de Zn:Ca dans les otolithes montrent des oscillations annuelles d'amplitude
In the production of ethanol from lignocellulosic material, it is necessary to reach a high ethanol concentration after fermentation. Simply increasing the substrate concentration leads to stirring problems and inhibition of the enzymes and yeast in the process. Batch simultaneous saccharification and fermentation (SSF) of steam-pretreated spruce with 13.7% water-insoluble solids (WIS) (25% total
Contour feathers cover most of the avian body and play critical roles in insulation, social communication, aerodynamics, and water repellency. Feather production is costly and the development of the optimum characteristics for each function may be constrained by limited resources or time, and possibly also lead to trade-offs among the different characteristics. Populations exposed to different env
The present study aimed to investigate how the impact of several factors linked to geography would shape life-history traits in a gregarious species, using the pine processionary moth (PPM) Thaumetopoea pityocampa as a model system. PPM has a wide geographical distribution over the Mediterranean Basin, and it is a strictly gregarious species throughout larval development, where the total reproduct
Over the last few decades the increase in globalised trade has forced industrial companies all over the world to undergo major organisational reconstruction work, specifically in areas such as logistics and transport. Activities, that used to be managed within the company business model, are being outsourced to third parties to achieve flexibility and more efficient cost management systems. In tod
Populärvetenskaplig sammanftaaning: För 65 miljoner år sedan slog en extraterrestrisk kropp ner på Yucatán-halvön i södra Mexico. Nedslaget orsakade ett av de största massutdöendena i historien, då bland annat dinosaurierna dog ut. Nedslaget kan ha varit en följd av ett tillfälligt ökat asteroidflöde i inre solsystemet som orsakats av att en jätteasteroid i asteroidbältet mellan Mars och Jupiter bAn impact crater is the result of a collision between a large and a smaller body. On Earth most of the cratering record has been erased because of tectonic processes and weathering. The Moon, however, displays a nearly complete record of impact events over the last 2 Gyr, and evidence of impact cratering events nearly 4 billion years old. The same family of impactors is responsible for the formati
Nuclear activity in Iran has during last years been a widely discussed topic worldwide, as well as an important element in international relations. United States has looked for allies in attempts to isolate Iran politically and economically. India and Russia are powers of growing importance with interests in Iran. So far, both countries have cooperated with the US in IAEA although not completely f
Genetics as a science has roots in studying phenotypes of relatives, but molecular approaches facilitate direct measurements of genomic variation between individuals. Agricultural and human biomedical research are both emphasizing genotype-based instruments, such as polygenic scores, but unlike in agriculture, there is an emerging consensus that family variables act nearly independently of genotyp
In the Swiss canton of Geneva, an energy efficiency portfolio has been operated since 2009. In contrast, such programs have been in place for more than 40 years in the US. There are numerous lessons to be learnt from their experience. We have therefore conducted a comparative analysis including Geneva and 11 leading states in the US, with the objective to identify explanatory factors for the succe
Metal joining remains an essential yet challenging process in manufacturing, particularly for components with small dimensions, multiplex, delicate geometries, or dissimilar metals, where conventional joining methods can be insufficient. Here, we introduce Gas Actuated Bonding (GAB), a novel joining method that employs gaseous melting-point-depressant (MPD) agents to induce a diffusion-active stat
Water has long been a strategic resource in the semi-arid landscapes of Mesopotamia, a region spanning Turkey, Syria, and Iraq, where the Tigris and Euphrates rivers form the lifeline of societies. As water scarcity intensifies due to a combination of climatic stressors and anthropogenic pressures, the governance of transboundary rivers has become critical for ensuring health, food security, and r
Insect diapause is a pre-programmed alternative developmental pathway induced to survive adverse environmental conditions and is characterized by an absence of development, metabolic suppression and increased stress resistance. While the hormonal regulation of diapause induction has been studied extensively, clear molecular hypotheses on how low-temperature driven diapause termination is controlle
