This book develops “Macroeconomic Uncertainty Strategy” (MUST) as a tool for coping with the impact of macroeconomic fluctuations on risk management, performance assessment, and strategies for value enhancement. The essential elements of a corporate strategy for managing uncertainty in the macroeconomic environment includes setting corporate objectives for risk management, measuring risk, choosing

The paper presents sufficient and almost necessary conditions for the presence of periodic solutions for zero dynamics of virtually constrained under-actuated Euler-Lagrange system. This result is further extended to detect periodic solutions for a class of hybrid systems in the plane and analyze their orbital stability and instability. Illustrative examples are given.

Semipermeable membrane devices (SPMDs) are passive samplers capable of concentrating hydrophobic chemicals from water, sediments, soil and air. They consist of layflat polymeric membrane such as polyethylene containing a thin film of synthetic lipid such as triolein. The transport of hydrophobic chemicals through the membrane into the lipid is governed by the process of passive diffusion. Therefor

Popular Abstract in Swedish Aerob kapacitet, i dagligt tal konditionen, är den maximala förmågan att utföra ett fysiskt arbete karaktäriserat av den maximala syreförbrukningen (V'O2max). Detta maximala arbete kan endast utföras en begränsad tid, till stor del beroende på en tilltagande anaerob metabolism, vilken bl.a. avspeglas som en ökning av utvädrat CO2 i lungorna. Längre tids arbete kan emellDifferent methods are proposed to assess the aerobic capacity. A novel scale, rating of perceived capacity (RPC) based on metabolic equivalents (METs) from 1 to 20, is presented. Selected MET values are linked to physical activities. Comparison of the rating with an exercise test in a group of women revealed that a correction based on age more accurately predicted the maximal exercise capacity. An

The finite element method has been used to analyse three topologies of iron-powder electrically magnetized synchronous machines. The first topology has the field winding placed in magnetically conducting end-plates, eliminating the need of slip-rings. In the second topology this is achieved by placing the winding above the outer rotor, and the third topology corresponds to the more conventional de

Popular Abstract in Swedish Etanol, dvs vanlig alkohol, från biomassa såsom energiskog, jordbruksavfallsrester och skogsavverkningsrester, är tänkt att användas som motorbränsle och ersätta fossila bränslen som bensin och diesel. Etanol är dyrare än bensin, men etanol är ett mera miljövänligt alternativ. Koldioxiden som bildas vid förbränningen av etanol tillverkad av biomassa ökar ej den totala kThe fermentative performance of bacteria, yeasts, and filamentous fungi was investigated in a pentose (xylose)-rich lignocellulosic hydrolyzate. The filamentous fungus Fusarium oxysporum and the xylose-fermenting yeast Pichia stipitis were found to be very sensitive to the inhibiting hydrolyzate. Recombinant xylose-utilizing Saccharomyces cerevisiae showed very poor ethanol formation from xylose;

Högre utbildning och forskning är en av de samhällsarenor där kvinnors position radikalt har förändrats de senaste trettio åren. Kvinnor är inte länge en minoritet inom akademin i stort, samtidigt som män fortfarande dominerar på ledningspositioner och professorstjänster. Andra minoritiserade grupper har också uppnått en större närvaro och synlighet. Policy för jämställdhet och mångfald är ofta ce

Abstract Inducible plant responses to damage, i.e. inducible defence responses and compensatory growth responses, are theoretically examined in an evolutionary and ecological context. Inducible defences are generally considered to be beneficial under conditions of low risk of herbivory and when initial damage is moderate. This study indicate that under these circumstances, localized defence respon

This paper presents an approach to validity and related questions of empirical research starting from and aiming at an understanding of the individual’s life-world experience strictly from the point of view of the individual himself and fitting to the theoretical frame of reference for the development of the ontological and methodological reflections of Husserlian phenomenology. I introduce a meth
