We have compiled data on the occurrence of a threatened beetle, Osmoderma eremita, in Sweden. The species inhabits tree hollows with wood mould. The data were compiled from field surveys conducted in 1993-2003, using pitfall traps at 401 localities and using wood mould sampling at 104 localities. We have also gone through published data and all larger Swedish museums and registered old records. O.
An algorithm for the burst detection and location in water distribution networks based on the continuous monitoring of the flow rate at the entry point of the network and the pressure at a number of points within the network is presented. The approach is designed for medium to large bursts with opening times in the order of a few minutes and is suitable for networks of relatively small size, such
OBJECTIVES: To determine what constitutes normal changes in the uterine cervix visible at transvaginal ultrasound examination from 24 gestational weeks until delivery in nulliparous women delivering at term. DESIGN: Cervical length and width were measured using transvaginal ultrasound, and the inner cervical os was assessed as being closed or open every 2 weeks from gestational week 24 until deliv
We suggest a physical picture of the catalytic act combining together the energy transfer and the synchronisation of the best electron density in the reactant and active site as a consecutive sequence of events. Activity and selectivity at molecular level are defined. Geometry requirements seem to be linked to energy and time requirements. Our proposal for developing new catalysts at the molecular
DNA ploidy has been shown to be a predictive parameter for prognosis in various solid tumours. The prognostic value of DNA-ploidy in gastric cancers is still a matter of controversy. A possible explanation for the discrepant results reported in the literature could be sampling error in tumours with multiple stemlines differing in DNA-ploidy. In order to determine whether or not such heterogeneity
n order to make attribute grammars useful for complicated analysis tasks, a number of extensions to the original Knuth formalism have been suggested. One such extension is the collection attribute mechanism, which allows the value of an attribute to be defined as a combination of contributions from distant nodes in the abstract syntax tree. Another extension that has proven useful is circular attr
Popular Abstract in Swedish Avhandlingen undersöker sambanden mellan ekonomisk tillväxt, energianvändning och koldioxidutsläpp i den svenska ekonomin 1800-2000. Genomgripande omvandlingar av teknologier har ägt rum i Sverige under de senaste två hundra åren, vilket har lett till högre inkomster, bättre kvalitet på produkter och en förändrad sammansättning på BNP. Jordbrukssamhället har gett vika fLarge transformations of technologies have occurred in the Swedish economy during the last two centuries, resulting in higher income, better quality of products and changing composition of GDP. An agrarian society has given way to an industrial society and lately to a post-industrial phase. The energy supply systems have changed, from traditional energy carriers, such as firewood and muscle energy
Corruption is widely recognised for distorting incentives and impeding economic growth. Less acknowledged are the effects of corruption on environmental issues such as the implementation of environmental regulation. Building on previous findings that have identified a negative relationship between corruption and environmental quality, this study sets out to investigate the impact of corruption lev
Den 8 november 2024 infördes självständigt förverkande i 36 kap. 5 § brottsbalken (1962:700) (BrB) som en del av en större reform av förverkandelagstiftningen. Förverkandeformen har huvudsakligen motiverats med att det behövs effektiva verktyg för att bekämpa den organiserade brottsligheten och neutralisera brottsvinster. Samtidigt rör det sig om ett tvångsingrepp med potentiellt långtgående konseOn 8 November 2024, non-conviction-based confiscation was introduced into Chapter 36, Section 5 of The Swedish Criminal Code (1962:700) as a part of a broader reform of the confiscation legislation. This measure has primarily been justified with regards to the need for more effective tools to combat organised crime and neutralise criminal proceeds. At the same time, it is a coercive measure with p
This research bears the research gaps of Chinese stand-up comedy and female stand-up comedians in mind, aiming to contribute to the lesser researched field of Chinese female stand-up comedy. Audience research is the bedrock of this research which sheds light on how audiences define, interpret and evaluate the genre of stand-up comedy and female stand-up comedy. To narrow the topic down, Rock &

The shape of a Belleville washer ring is optimized with the purpose of tailoring its mechanical response. The optimization is carried out using structural shape optimization with regards to large deformations. In order to accurately model boundaries, B-splines are utilized as they are closely related to the de facto-standard used in most of todays CAD systems. Furthermore, the structural analysis
Surrogate motherhood is a relatively controversial method of assisted reproduction, as it raises ethical questions about the potential risk of exploitation versus the right to self-determination, if it is done with the child’s best in mind and whether or not it is problematic for the family constellation. The purpose of this paper is to examine the approach to altruistic surrogate motherhood in Sw
När ett företag vill bedriva en miljöfarlig verksamhet krävs det att de beviljas ett tillstånd för verksamheten i enlighet med miljöbalken (1998:808). När systemet för tillståndsprocessen sattes i bruk var lagstiftaren tvungen att göra flera avvägningar, bland annat mellan nyttan för miljön och ekonomin. Tillståndsprocessen ger myndigheter och domstolar chansen att granska verksamheten. Den ger ocWhen a company wants to create a new business that can be regarded as harmful for the environment, the company in question must apply for a permit in accordance with the Swedish Environmental code (1998:808). The legislator, when creating this process of applying for a permit, had to balance multiple different interests. Some of these interests include the environment and the economic aspect. This
Temperature dynamics for a building heated by hot-water radiators are studied in this work. The emphasis has been put on deducting an equation for calculating radiator temperatures and temperature dynamics out of given datas on the construction of the heating system.
Different models for approximation of radiators are compared and the heating effect as a nonlinear function of the temperature
Given the importance of copper prices to investors, governments, and policymakers, this paper investigates short-term price predictability using VAR and XGBoost models. All models are trained with historical data from November 2021 to December 2022 and using MSE, RMSE and MAE for evaluating the model performance. The results show that the XGBoost model outperforms VAR models, implying that machine
In 2020, Zenuity was split up and the new company, Zenseact became a subsidiary to the car manufacturer Volvo Cars, owning 86,5% of the company. In the end of 2022, Volvo Cars acquired the rest of the company and became fully owner of Zenseact. Being a knowledge heavy company with ambitious developers at the core of the organization, Zenseact develops driving assistance software powered by advance
In the last decade, with the growing demand for efficient and more sustainable products that reduce our CO2 footprint, progresses in Additive Manufacturing (AM) have paved the way for optimized heat exchangers, whose disruptive design will heavily depend on predictive numerical simulations. Typical AM rough surfaces show limited resemblance to the artificially constructed rough surfaces that have
