The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meat the authorities requirements given in building codes. All these situations require good calculation methods. The main
Synen på alkoholmissbruk har skiftat genom tiderna. Till en början sågs missbruket som en samhällsfara där lösningen var att isolera individen från övriga samhället. Detta synsätt skiljer sig från det nuvarande där det finns ett samhällsintresse för en arbetstagare som lider av alkoholmissbruk för att denne ska få tidiga stödinsatser och förhoppningsvis med hjälp av dessa åtgärder kvarbli i arbetsThe perception of alcohol abuse has evolved over time. Initially, abuse was seen as a societal threat, with the solution being to isolate the individual from the rest of society. This perspective differs from the current approach, where there is a societal interest in supporting an employee suffering from alcohol abuse through early interventions, The aim is to support the employee to remain in th
Nature-based Solutions (NBS) are recognized as key actions for achieving sustainable and resilient development. They are being implemented in a variety of fields, such as urban planning, and offer a wide range of social, environmental, and economic benefits. While there has been a significant increase in the number of NBS practices in recent years, there remains a notable imbalance, with a bias to
Background: Non-motor symptoms (NMS) substantially impair quality of life in Parkinson's disease (PD) patients, yet treatment gaps persist. Guideline adherence for NMS management remains poorly characterised. Also, reliable symptom monitoring tools are needed: the Parkinson’s KinetiGraph (PKG) for sleep assessment and the Home Diary (HD) for motor fluctuations both require further validation.Aims:
Overheating in buildings is becoming a major concern and cause for various health issues. Existing research and previous studies on the issue were examined to acquire relevant information about the definition of overheating, its possible causes, and the heath impacts it could have on human health. The review included data on the current status of thermal comfort and overheating regulations in Swed
Under år 2010 genomfördes en lagändring rörande den svenska bestämmelsen i BrB 4 kap. 1a § avseende människohandelsbrottet. Ändringen föranleddes av att problematik avseende bestämmelsens tillämpning och effektivitet hade uppmärksammats. Inom ramen för den utredning som tillsattes med anledning av detta identifierades fem problemområden avseende människohandelsbestämmelsens utformning; i) användanIn 2010, a legislative amendment was passed regarding the Swedish Penal Code provision in chapter 4 article 1 a, regarding human trafficking. The amendment was induced after problems concerning the effectiveness of the provision that had been observed. Within the proposal from the appointed committee in response to this, five problem areas was identified; i) the use of improper means, ii) the word
Buildings from the so called Million programme has a high use of energy and in addition, there are many such houses. The need for them to be retrofitted is big. The City of Helsingborg has set a climate goal which states that the city in 2035 should be neutral in energy use which put a lot of pressure on the real estate owners in the city. All new buildings has to be energy efficient and older bui
The particularities surrounding the way decentralized multinational companies are structured and governed can determine the success or failure of integrating sustainability aspects into their units’ approach of doing business. The choice of pursuing a decentralized avenue over a headquarter-driven one in managing sustainability can have a significant influence over the coherence of Group1-wide str
This article provides a step-by-step guideline for measuring and analyzing visual attention in 3D virtual reality (VR) environments based on eye-tracking data. We propose a solution to the challenges of obtaining relevant eye-tracking information in a dynamic 3D virtual environment and calculating interpretable indicators of learning and social behavior. With a method called "gaze-ray casting," we
In the present study, using retinal ischemia as a model, we examined if different periods of ischemia and recirculation influenced the generation of reactive oxygen species, i.e. in hydrogen peroxide generation and nitroblue tetrazolium (NBT) reduction. Ischemia was induced for 30 and 90 min by ligation of the optic nerve with the vessels and recirculation was established by removing the ligature.
A new negligible depletion extraction procedure was proposed for equilibrium sampling of 4-tert-octylphenol (OP) and 4-nonylphenol (NP) into a thin film of 1-octanol supported on a hollow fiber membrane. This thin liquid film extraction technique was directed at the determination of ( 1) freely dissolved concentrations, ( 2) distribution coefficients to 1-octanol (D-ow), and ( 3) binding to dissol
Akylphenols (4-nonylphenol, 4-(1,1,3,3-tetramethylbutyl)-phenol and 2,6-bis(1,1-dimethylethyl)-4-ethylphenol) have been directly extracted from water samples using neat supercritical carbon dioxide and collected on an octadecyl silica (ODS) solid phase trap. The extraction cells were equipped with home-built assemblies containing hydrophobic membranes. The assemblies were inserted at each end of t
Using Monte Carlo simulation of 99Tcm single-photon-emission computed tomography (SPECT), we investigate the effects of tissue-background activity, tumour location, patient size, uncertainty of energy windows, and definition of tumour region on the accuracy of quantification. The dual-energy-window method of correction for Compton scattering is employed and the multiplier which yields correct acti
The purpose was to study age related changes in circulatory system via Ballistocardiography (BCG) by utilizing Electromechanical Film (EMFi) sensors by gradually changing the ambient temperature from a thermoneutral area to cold direction. ECG and BCG were recorded from a young person (23 years) and from an older person (78 years), both males. During the tests, brachium blood pressure (BP) and pul
Change Impact Analysis (CIA) during software evolution of safety-critical systems is a labor-intensive task. Several authors have proposed tool support for CIA, but very few tools were evaluated in industry. We present a case study on ImpRec, a recommendation System for Software Engineering (RSSE), tailored for CIA at a process automation company. ImpRec builds on assisted tracing, using informati
The present work was initiated based on an industrial demand for designing a high-bandwidth hexapod of an advanced large optical telescope. In this dissertation, we have generalized this industrial problem to fully-parametric models of the hexapod vibrations as well as analytical studies on dynamic isotropy in parallel robots, which can be directly used in any hexapod application. Hexapods (also k
MicroRNAs (miRNA) play an important role in various biological process by regulating gene expression. Their abnormal expression may lead to cancer. Therefore, analysis of such data may discover potential biological insight for cancer diagnosis. In this regard, recently many feature selection methods have been developed to identify such miRNAs. These methods have their own merits and demerits as th
The paper/presentation gives an overview of Peer-Assisted Study Schemes (SI-PASS) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult” courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular education and are guided and facilitated by a “senior” student, the SI-PASS leader. The sessions are based on
Background/aims: During the last decade, improved neonatal care has resulted in increased survival of the most immature infants and improved health of more mature infants. We hypothesise that this has affected incidence and treatment of retinopathy of prematurity (ROP), enabling guidelines for screening to be modified. Methods: In Sweden, all infants with gestational age (GA) at birth ≤30 weeks ar
The catanionic system didodecyldimethylammonium bromide (DDAB)-sodium taurodeoxycholate (STDC)-D2O is characterized by an exceptionally extended L1 region. The comparison of self-diffusion coefficient of the solvent and the DDAB embedded in the micelles provided information about hydration of the aggregates. Moreover, correlating self-diffusion and 14N NMR relaxation measurements new insight could
