Life cycle assessment (LCA) is an established method to assess the various environmental impacts associated with all the stages of a building. The goal of this project was to calculate the environmental releases for a whole office building and investigate the contribution in terms of environmental impact for different parts of the building, as well as the impact from different stages of the life cLife cycle assessment (LCA) is an established method to assess the various environmental impacts associated with all the stages of a building.

Spent sulfite liquor (SSL) is a byproduct of the sulfite pulping process of wood. SSL usually contains monosugars and lignosulfonates, which are fermented to produce ethanol and dried to generate lignosulfonate salts. However, the SSL that was used in this work was derived from the first step of a 2-step sulfite pulping process of softwood under mild pulping conditions in the first stage of cookin

This paper analyzes land-system dynamics changes due to energy infrastructure development and explores the environmental and social ramifications of hydraulic fracturing, through a case study in Central Appalachia. Grounded in photographic data, satellite images, and ethnographic material, this study demonstrates landscape and embodied experiences of change over time. Data show major shifts in ter

Lorcaserin, which is a selective agonist of serotonin2C receptors (5-HT2CRs), is a new FDA-approved anti-obesity drug that has also shown therapeutic promise in other brain disorders, such as addiction and epilepsy. The modulation of dopaminergic function might be critical in the therapeutic effect of lorcaserin, but its exact effect is unknown. Here, we studied the effect of the peripheral admini

The surface electron density significantly affects the photocatalytic efficiency, especially the photocatalytic CO2 reduction reaction, which involves multi-electron participation in the conversion process. Herein, we propose a conceptually different mechanism for surface electron density modulation based on the model of Au anchored CdS. We firstly manipulate the direction of electron transfer by

We used in situ hybridization histochemistry to study the expression of the two vesicular monoamine transporters (VMAT1 and VMAT2) during embryonic development in the rat. In the adult rat VMAT2 is present exclusively in neuronal tissues and VMAT1 is present in the adrenal medulla and in certain intestinal endocrine cells. We found that both transporter molecules are more widely expressed during d

Objectives To determine whether videos taken by parents of their infants' spontaneous movements were in accordance with required standards in the In-Motion-App, and whether the videos could be remotely scored by a trained General Movement Assessment (GMA) observer. Additionally, to assess the feasibility of using home-based video recordings for automated tracking of spontaneous movements, and to e

As an alternative to clear-cutting, variable-retention harvesting is now standard forest management practice on the coast of British Columbia and in temperate forests globally, due to the benefits associated with maintaining mature forest species and forest structural diversity. Although there is some evidence that variable-retention harvesting, particularly single-tree (dispersed) retention will

The transient electromagnetic (TEM) method is widely used in resistivity mapping but rarely applied in monitoring experiments. In this study, we present an algorithm to invert time-lapse TEM data, with inversion of both synthetic data and field data. Three main novelties distinguish this new inversion algorithm: i) a multiple-mesh approach is used for the definition of model parameters and forward

Protein scaffolds direct the organization of amorphous precursors that transform into mineralized tissues, but the templating mechanism remains elusive. Motivated by models for the biomineralization of tooth enamel, wherein amyloid-like amelogenin nanoribbons guide the mineralization of apatite filaments, we investigated the impact of nanoribbon structure, sequence, and chemistry on amorphous calc

Affibody molecules, small (7 kDa) scaffold proteins, are a promising class of probes for radionuclide molecular imaging. Radiolabeling of Affibody molecules with the positron-emitting nuclide 68Ga would permit the use of positron emission tomography (PET), providing better resolution, sensitivity, and quantification accuracy than single-photon emission computed tomography (SPECT). The synthetic an

The design and construction of large infrastructure projects require detailed information on subsurface geology and identification of potential risks. Geophysical investigations can provide important information for design and risk assessment provided that the optimal method and interpretation approach is adopted.This work presents results from seismic refraction surveys carried out along a planneThe design and construction of large infrastructure projects require detailed information on subsurface geology and identification of potential risks.

ATTACHMENT of foot-and-mouth disease virus (FMDV) to its cellular receptor involves a long and highly antigenic loop containing the conserved sequence, Arg-Gly-Asp, a motif known to be a recognition element in many integrin-dependent cell adhesion processes1-7. In our original crystal structure of FMDV the Arg-Gly-Asp-containing loop ('the loop'), located between β-strands G and H of capsid protei

Within the next 30 years, two thirds of the human population will live in a city. This growing urban population requires a major shift in the way we produce and distribute food, since conventional agriculture practices are responsible for climate change, biodiversity losses, pollution of waterways, soil degradation, etc. Urban and peri-urban agriculture and forestry represent one of the strategies

Omkring 600 barn och tonåringar arbetar på Managuas stora soptipp, denbstörsta i Nicaragua. De samlar och sorterar avfall på den öppna tippen, sombtäcker ett 7 km2 stort område i stadens utkant vid stranden av Managuasjön. Sådant arbete, som förekommer i många stora städer i utvecklingsländer, ansesbvara ett av de mest riskfyllda typerna av barnarbete som finns. Ändå är kunskapen om sådant arbete About 600 children and teenagers work at Managua's landfill, the largest in Nicaragua. They collect and sort waste at the open dump, which covers an area of 7 km2 on the outskirts of the city on the shores of Lake Managua. Such work, which occurs in many large cities in developing countries, is considered to be one of the riskiest types of child labor that exists. Nevertheless, knowledge of such w

Consumption was one of the spheres of everyday life shaken and remoulded by the collapse of socialist regimes at the end of the 20th century. Especially in times of rapid change, a moral economies lens is a fruitful means to understand the contentious moral landscape and moral tensions that pervade consumption behaviour, norms and discourse. Important areas of consideration in post-socialist socie
