A dynamic beam system loaded harmonically in the axial direction and constrained in the transverse direction is modelled using different theoretical descriptions. Results from an experimental set-up are compared to calculations using Bernoulli as well as Timoshenko beam theories. Some results from investigations of this beam system unveiling its chaotic nature have earlier been presented, but here
Results from the design of a high-pressure chamber and its components, recently developed at the Lund Institute of Technology, are presented. The results show that at high pressures, when the lubricants have solidified, the density varies linearly with the pressure and the shear strength also increases nearly linearly with pressure. This is also true for the investigated gasses when they are compr
This paper compares the extraction effectiveness of six different commonly applied extraction techniques for the determination of PCBs in soil. The techniques included are Soxhlet, Soxtec, ultrasonication extraction, supercritical fluid extraction, microwave-assisted extraction and accelerated solvent extraction. For none of the techniques were the extraction conditions optimized, but instead the
Objective: To develop a simple, easily administered pencil-and-paper questionnaire to determine the degree to which behavioral patterns play a role in smoking dependence. Methods: A modified Delphi technique was used to identify initial questions and to eliminate obvious duplications. Phase 2 utilized multiple statistical methods (principal components analysis, cluster analysis, stepwise multiple
Woven convolutional codes with one tailbiting component code are studied and their generator matrices are given. It is shown that, if the constituent encoders are identical, a woven convolutional encoder with an outer convolutional warp and one inner tailbiting encoder (WIT) generates the same code as a woven convolutional encoder with one outer tailbiting encoder and an inner convolutional warp (
This paper takes the treatment of antonymy in Collins COBUILD Advanced Learner's English Dictionary (2003) as the point of departure for a discussion about the principles of antonym inclusion in dictionaries and corpus methodologies in lexicology. CCALED includes canonical antonyms such as good/ bad and dead/alive, as well as more contextually restricted pairings such as hot/ mild and flat/fizzy.
This article investigates the relationship between universities and academic spin-offs, with special emphasis on the antecedent conditions of, and the nature of the linkages that the spin-offs form, as well as the means for sustaining them. The present research uses an instrumental case study approach, and is also an instance of a collective case study as four companies of various size and activit
Abstract in UndeterminedThe primary aim of the present study is to reveal the creative awakening of Michalis Ganas, Maria Kirtzaki, Tzeni Mastoraki and Kostas Papageorgiou, four poets of the Greek 1970s Generation. All four poets were born during the decade of the 1940s. The thesis approaches the poets entire authorship from their debut, end of 1960s beginning of 1970s, until the present day, to d
The dinoflagellate cyst Lunnomidinium scaniense gen. et sp. nov. is present in the lower part of a thin sequence of Rhaetian sedimentary rocks exposed in the Lunnom Coal and Clay Pit in NW Scania, southern Sweden! It occurs in diverse, Rhaetian palynomorph assemblages, dominated by spores and pollen, but with rare specimens of the dinoflagellate cysts Rhaetogonyaulax rhaetica (Sarjeant) Loeblich a
The purpose of this master thesis was to provide reliable information to improve off-piste skiers’ knowledge, behaviour and risk management. This since research concerning human factors in the field of avalanches traditionally had been paid little attention. A literature review covering avalanche, traffic and risk literature and two surveys which gathered approximately 2000 responses were conducte
The purpose of this study is to gain a deeper understanding about the consumption of contemporary charity in Western society on the example of the Swedish breast cancer charity Rosa Bandet. The study reveals exciting nuances of contemporary charity consumption, among them the glamourisation and disarming of cancer, the commercialisation and merchandisation of charitable giving, the changing role o
Penningtvätt har länge varit ett uppmärksammat problem, men inte förrän på senare år, särskilt efter den 11 september 2001 och terroristattackerna i USA har stora krafttag gjort att bekämpningen av problemet kommit igång. Bekämpningen och förhindrandet av penningtvätt och finansiering av terrorism är även viktigt utifrån ett större perspektiv. Om man kan strypa finanserna för kriminell verksamhet,Money laundering has for a long time been an acknowledged problem, now more than ever. Especially after 9/11 2001 and the terrorist attacks in the USA, joint efforts have made combating the problem a serious matter. Combating and prevention of money laundering and terrorism financing is also important from a larger perspective. If you can close off finances of criminal activity, you are one step c
The credit is a financial service which holds a vital role to the transactions between the financial and non-financial enterprises with their customers. The goal of credit is to aid the legal and physical persons to successfully face and thus to overcome their difficult economical situations. Due to the fact that the VAT exemption status of granting, negotiation and management of credit causes neg

Using the methodology introduced by Campbell et al. (2001), we decompose and evaluate the historical volatility patterns of the Swedish stock market in the time period 1985 - 2012. The volatility at all component levels, including idiosyncratic risk, appear to be fairly stable throughout the sample, with the exception of temporary dramatic increases during periods of economic distress. As opposed
