In order to improve the offered quality of service in a cellular network, load balancing between cells with momentarily different traffic loads can be applied. This can be accomplished through channel borrowing techniques where a cell requiring extra capacity borrows a channel from a less loaded cell in the same region. However, the borrowing of a channel results in an alteration of the channel re

he basic idea of the particular way of understanding mental phenomena that has inspired the "cognitive revolution" is that, as a result of certain relatively recent intellectual and technological innovations, informed theorists now possess a more powerfully insightful comparison or model for mind than was available to any thinkers in the past. The model in question is that of software, or the list

Popular Abstract in Swedish Ett proteins funktion bestäms av dess tredimensionella struktur. Proteiners stora betydelse för liv, så som vi känner det, och vår önskan att förstå det leder oss därför till att studera proteiners struktur. Målet kan vara att förstå en specifik process i en specifik art, kanske för att hitta ett botemedel mot en sjukdom som beror på ett icke-fungerande protein, eller mWe have studied protein motions with nanosecond time-resolved crystallography. The release of carbon monoxide from its complex with myoglobin (MbCO) was triggered by nanosecond laser pulses. X-ray data were collected with time delays ranging from 4 ns to 1.9 ms using the Laue method, at the European Synchrotron Radiation Facility in Grenoble. For the first time point, X-ray pulses of 150 ps durati

Syftet med denna undersökning var att bestämma en 1 kg isvästs kylverkan på kroppen vid brandmansarbete. Testerna genomfördes i en klimatkammare, i en container med extrem strålningsvärme och i ett rökdykningshus med värme och tungt arbete. Den faktiska kylverkan mättes också med en termisk docka. Fyra erfarna brandmän deltog i försöken. I alla tester bar försökspersonerna standardklädsel för branThe aim of the present study was to examine the effects of wearing a light-weight ice-vest (1kg, water) on physiological and subjective responses in fire fighter’s work. The experiments were carried out in a climatic chamber, in a container under extreme radiant heat, and during simulated smoke-diving. In addition, the physical cooling effect of the ice-vest was measured with a thermal mannequin.

När den svenska välfärdsmodellen växte fram var det trygghetssystemen och arbetsmarknadspolitiken som stod i centrum. Under denna tid förvandlades familjen från att vara en enskild angelägenhet till att bli föremål för politiska ingripanden. Familjen blev ett eget politikområde, vars mål och medel kom att diskuteras under flera decennier. Historien om familjepolitikens framväxt är en historia om i

Popular Abstract in Swedish Salt ackumulering på jordbruksmark är en historisk såväl som ett av de potentiellt största problem som mänskor har haft och har. Forskare har undersökt och försökt lösa detta problem under en lång tid. Över 20 reviewer har publicerats om ämnet under de senaste fem åren. I denna avhandling redogörs summariskt för utbredningen av salt stress i dagens jordbruk, samt de toSalt stress is one of the historically as well as potentially largest agriculture problem humans have faced. Researchers have investigated and tried to solve this problem for a long time. Over 20 reviews have been written on this topic the last five years. In this thesis the extent of salt stress in today's agriculture, the toxic and damaging effects on plants and bacteria exposed to salt stress,

We present a new study of deep star counts in the Local Group dwarf spheroidal (dSph) in Ursa Minor. Both the luminosity function (LF) and the color-magnitude diagram (CMD) of the unevolved stars are compared with the LF and CMD of the old, metal-poor globular cluster M92. The main sequence locations and turn-offs are identical within the errors. Since we. know from the brighter evolved stars that

Naturens inverkan på arbetet för de som arbetar utomhus eller i nära anknytning till naturens förutsättningasr. Både de negativa och besvärliga erfarenheterna samt positiva erfarenheter som stimulerar arbetslusten och trivseln. Naturens betydelse för ett teoretiskt arbete och ett praktiskt arbete.

The existing research has produced a useful palette of ideas that help us make sense of the phenomenon of organizational control. But there is a trend that hampers the interpretative possibilities: a heavy bias towards vertical forms of control. It is frequently assumed that the control that operates in organizations has its origin in the actions of managers. This assumption is especially problema

In this chapter we explore the meaning of 'care' and 'treatment' in a specific context -- contemporary prisons in Sweden -- as they are displayed and used in interview talk with inmates and staff members. Drawing on unstructured interviews from two sociological projects we develop an ethnomethodological analysis to uncover how 'care' and 'treatment' are used as identificatory as well as moral reso

A model for evolution of cracks as a result of strain-assisted corrosion is presented. The considered cracks possess a realistic geometry, where the tip region is an integral part of the crack surface instead of being a singular point. This geometry is either implicitly defined or is a consequence of crack nucleation from surface irregularities. The evolution model poses a moving boundary value pr
