Many of the physiological adaptations evolved in terrestrial invertebrates to resist desiccation have also been shown to enhance the survival of low temperatures. In this study we have examined temporal changes in the physiology of the collembolan Folsomia candida during acclimation to mild desiccation stress (98.2% RH), and how physiological changes correlate with resistance to subsequent cold sh

By introducing spectral or polynomial functions to perturb the shape of the rotor in an electrical machine that was previously optimized by conventional means, it was shown that performance parameters can be further improved, in some cases significantly. This was accomplished by developing and applying an optimization method designed for use with a commercial finite element simulation software (Ma

The aim of this essay was to illustrate how poor women with children in Nicaragua saw themselves and the role they played. For the realization of this study I used the qualitative method consisted in interviews of six women who live in a poor neighborhood in the city of León. To be able to reach this essay’s purpose, it was of the utmost importance to answer on what was their role, what conception

According to the Convention on the Rights of the Child (CRC) in all actions concerning children, whether undertaken by public or private social welfare institutions, courts of law, administrative authorities or legislative bodies, the best interests of the child should be a primary consideration (CRC article 3 p. 1). However, it is not regulated in the law or in CRC what is considered to be the ch

The purpose of this study was to examine the factors contributing to the emergence and persistence of collective action in chengzhongcun (literally known as “village(s) amid the city”) in China. Based on a one-and-a-half month fieldwork in Guangzhou, China, this study was designed to answer the questions of what triggered collective action in chengzhongcun and how and why chengzhongcun villagers c

With the help and mediation of international involvement, a peace negotiation, succeeding previous futile attempts to put an end to a civil war finally led to the signing of the Chapultepec peace accords. The first presidential elections in 1994 were won by right-winged party ARENA, who furthermore would hold power through elections for 15 years to come. In the 2009 elections, left winged party FM

Problem discussion: BCC:s product portfolio includes a transplanting machine that plants seedlings from trays to the field. The machine is more than 10 years old and need improvements to meet future demands from customers around the world. The main issues are that the machine does not have the capacity to detect missing plants from trays, the planting speed needs to be higher and the row distance

This Master Thesis was executed on behalf of Faiveley Transport AB, Landskrona, Sweden, between February and September 2007. The work was written under the Division of Machine Design at Lund Institute of Technology. The Faiveley Group is one of the world’s leading suppliers of railway systems and services, and the thesis was conducted as a product development project with the objective to design a

We present a set of spectrally and temporally resolved clinical fluorescence data-with two separate excitation wavelengths-that was recorded in vivo. We demonstrate that data in the spectral and temporal domains are in certain ways coupled and provide a method for integrated and effective parameterization of spectrally and temporally resolved fluorescence (i.e., time-resolved emission spectra). Th

Oxidation phenomena on Laves phase forming Ti-Nb stabilized ferritic stainless steel (EN 1.4509) were studied at 650 degrees C by electron microscopic and electron spectroscopic methods. These investigations reveal a strong competition between Nb and Si for interfacial oxidation at the oxide metal interface that is affected by different segregation rates of Nb and Si at elevated temperatures. In p

Many alloys undergo complex changes in local chemistry in the vicinity of weldments due to the thermal excursion during welding. The resulting changes in solute concentrations can lead to significant local variations in the unstrained unit cell parameter which, if not accounted for, can lead to serious error when determining residual stress by diffraction methods. Age-hardening aluminium alloys ar

In this work we report results of ferromagnetic resonance studies of a 6% 15 nm (Ga,Mn)As layer, deposited on (001)-oriented GaAs. The measurements were performed with in-plane oriented magnetic field, in the temperature range between 5 K and 120 K. We observe a temperature induced reorientation of the effective in-plane easy axis from [(1) over bar 10] to [110] direction close to the Curie temper

Objective: To describe a multidisciplinary program, given by an occupational therapist and a physiotherapist, for patients with stress-related disease in primary health care and to measure the effect of this program in terms of self-perceived health, degree of burnout, physical activity, symptoms, recreational activities, and psychological and physical well-being. Method: Retrospective study. Re

Background. An important outcome from the debate on whether wellness equals happiness, is the need of research focusing on how psychological well-being might influence humans' ability to adapt to the changing environment and live in harmony. To get a detailed picture of the influence of positive and negative affect, the current study employed the affective profiles model in which individuals are c

Grammar and epigram Grammarians of antiquity—the precursors later generations of classical philologists—were often the target of attacks by contemporary writers of satiric epigrams. Examples appear in collections of both Greek and Latin epigrams from the Hellenistic period down to the end of antiquity. Grammarians are generally depicted in them as pretentious humbugs, a pest both to poets, whose w

Background: University students are at a transitional stage in life characterized by increased independence, autonomous decision-making, reduced parental supervision, and heightened susceptibility to peer pressure.These dynamics expose them to various risks, including risky sexual behaviors, violence, and use of substances and alcohol. These risky behaviors often result in serious negative consequ

The purpose of this study was to examine creativity in psychosocial work. The aim issues where to find out how creativity develops in social work, why the relation is important for the innovativeness and how the creativeness can change a person. Through a qualitative method with interviews of four persons in psychosocial work and with one man who's a professor in philosophy, four relevant them

Tetra Pak Global Technical Support AB (GTS) is a company within the Tetra Pak group which main task is to supply the whole world with spare parts for all kinds of Tetra Pak machines. GTS supplies about half a million different parts, which demands a large purchase organisation. This thesis deals with the so-called Sourcing purchase, which is a term for purchase of non-forecasted parts that have no

The purpose of this paper was to examine how youths, age 18-20, experience the verdict to the probation service and how it affects their lives. We have examined the relation between youths and the probation service from a youth perspective, what kind of support and intervention they receive and how their surroundings react and respond on the verdict. Our research was based on a qualitative method
