Popular Abstract in Swedish Många material som ingår i tillverkade varor har kvar sina kvaliteter även när varorna är uttjänta. Men bara en liten del av dessa material återvinns idag på ett sätt som gör det möjligt att återanvända materialet för samma syfte och med bevarade egenskaper. I allmänhet har det industriella samhället fortsatt att praktisera en slit- och slängmentalitet, trots att det beMany anthropogenically-produced or beneficiated materials contained in “end-of-life” products retain a great proportion of the invested manufacturing work when discarded. Very few such materials are reconstituted and applied in new products at the same material inherent quality level as in their first lifetime – a process known as “closed-loop recycling”. In general, industrial society maintains a

In this article, the author discusses the implications of a 6+6-hour model for the production economy of the Finnish Company Essilor Oy. The theory of returns to scale has been used to analyse the results of the change from one 8-hour shift to the 6+6-hour-shift system. It is shown that the company Essilor attained a better production economy and increased profit by introducing a 6+6-hour-shift sy

BACKGROUND: The TT virus (TTV) is a newly identified blood-borne virus. Its association with disease is still unknown, and screening of blood donors has not been implemented. Several genotypes of the TTV have been identified. STUDY DESIGN AND METHODS: Three hundred seventy healthy blood donors were randomly selected and tested for TTV by the PCR method. Sequencing of a part of the genome was perfo

Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are know

Världshälsoorganisationen har, med hänsyn till den världsomfattande urbaniseringen och åldrandet, föreslagit att tillgängliga grönområden i städers utomhusmiljöer är en viktig aspekt för det hälsofrämjande åldrande. Med anledning av att det främst är den äldre andelen av äldre som ökar globalt, fokuserar denna studie på att undersöka tillgängligheten av grönområden för de äldre som bor i boenden sThe World Health Organization, have due to the current worldwide urbanisation and ageing trends, proposed that having available Urban Green Spaces (UGS) is an important factor for ensuring healthy ageing in urban areas. Since it is particularly the oldest proportion of the older adults that are increasing in global population statistics, this study focused exclusively on available UGS based on old

Green prescribing, the referral of patients to nature-based activities, has potential to bring co- benefits for psychological and physiological public health and for environmental health. Literature considers a major limitation to its effective implementation as a holistic, transectoral practice to be lack of a common language and tendency of actors involved to work within their respective paradig

Shared micro-mobility gradually becomes a crucial part of human daily transportation. To develop the shared micro-mobility, discovering the important influence factors of each travel mode is a key aspect. However, there are scarce studies that adopt machine learning methods to model travel choice between shared micro-mobility services and identify the crucial determinants for each mode. This study

In recent years, the field of mass spectrometry (MS) has grown significantly, allowing for shotgun proteomic experiments to be used increasingly in biomarker discovery experiments. However, using standard methods of MS not all peptides present in a sample may be identified. To combat this, a procedure termed alignment, or match-between-runs, is used to propagate identifications from one run to ano

Ökande oljepriser och en stigande efterfrågan gör idag undersökningar av alternativa petroleumreservoarer extra intressanta. Istället för att borra i den sedimentära berggrunden ges nu möjligheten att granska kristallina berggrundsreservoarer. Den här typen av borrning i kristallin berggrund äger rum på flera platser i världen, exempelvis i Vietnam och Yemen. Det norska företaget Lundin Norway AS Rising oil prices and an increasing global use of fossil fuels make the survey of alternative petroleum reservoirs of great importance. Instead of drilling in regular sedimentary successions, the possibility of investigating reservoirs in crystalline basement is in many places of economic interest. Reservoirs in crystalline basement rock are producing oil in several countries e.g. Vietnam and Yeme

Issue of study: Looking at the lack of strong fibers to form strong paper packaging in Indonesia, there are potentials to introduce Scandinavian long-fibered strong paper bag packaging in Indonesia. Two basic food categories, wheat flour and packaged rice, are chosen as the consumption rate is increasing in Indonesia. Indonesia is tropical country with high temperature and humidity level. In addit

The purpose of this essay is to analyse the status of good faith under the CISG in the light of article 7 of the Convention. The first part of this article reads: ''In the interpretation of this Convention, regard is to be had to its international character and to the need to promote uniformity in its application and the observance of good faith in international trade.'' Emphasis a

Världen står inför stora ekonomiska, sociala och miljömässiga utmaningar, vilket kräver en ökad innovationstakt och en acceleration av omställningen till en hållbar utveckling. Samhället förändras i en snabb takt och omställning kräver nya och starka samarbeten mellan industri och samhälle. För att arbeta mer effektivt och framgångsrikt med att uppnå FN:s 17 globala hållbarhetsmål har Sverige skap

Advantages and disadvantages with organic production have been studied in the scientific community and is greatly debated. Demands for organic products have risen the past years in Sweden and the objective in one of the governments environmental goal is to reach a 20 % organic production. But is organic production increasing sustainability in the agriculture sector? This study aims to compare orga

Eye Movement Desensitization Reprocessing (EMDR) has been investigated recently in false memories and specifically in the DRM paradigm. EMDR has been shown to decrease emotionality of the problematic memories in PTSD, but also to decrease false memories. No studies have to date shown how emotion and memory is effected by EMDR in the DRM paradigm when non-emotional wordlists are coupled with a nega

Parkinson's Disease (PD) is a debilitating motor function disorder due primarily to a loss of midbrain dopaminergic neurons and a subsequent reduction in dopaminergic innervation of the striatum. Several attempts have been made to generate dopaminergic neurons from progenitor cell populations in vitro for potential use in cell replacement therapy for PD. However, expanding cells from fetal brain w

The influence of gender, age, residential area, and socioeconomic status on the blood and serum levels of 13 trace elements was studied in boys and girls living in two Swedish cities with different socioeconomic and environmental characters. The same groups of adolescents were sampled twice, at ages 15 (n = 372) and 17 (n = 294) years. All the investigated factors were shown to be of importance. A
