The results of a preliminary investigation into the theoretical evaluation and study of the relationship between some room acoustical descriptors used for the subjective assessment of performance halls are considered. The concern is about three parameters, namely, the inter-aural cross-correlation coefficient (IACC), the early lateral energy fraction (ELEF) or a related measure, the spaciousness S

I investigate the field of tension between the national and the local level in spatial planning from a decision-making perspective. In doing so, I analyse the legal regulation for a large-scale 3G mobile infrastructure development in Sweden with a focus on how participation is expressed both in terms of the ‘law in books’ as well as empirically, ‘in action’. Theoretically, a model of decision maki

Since the first issuance in 1994, Swedish Government inflation indexed bonds have given a higher return then their nominal counterpart. This is despite the fact that investors can reduce the risks of inflation. Findings on other markets, as the US bond market, suggest that the higher return can be explained by the lower liquidity of inflation indexed bonds relative the nominal bonds. The aim of th

In this study the strain rate effects on the tensile and compressive properties of nano-crystalline nanoporous gold (nc-NPAu) are investigated by performing molecular dynamics simulations. In order to examine the role of strain rate,atomistic models of nc-NPAu structures with three different grain size are generated through a novel modeling technique based on the Voronoi tessellation method.

ETEM, Environmental Transmission Electron Microscopy är en teknik som ger möjlighet att betrakta reaktioner mellan fasta föreningar, högsmältande vätskor och gaser i realtid, och med atomär upplösning.Ett Hitachi 3300S ETEM har designats och uppförts av nCHREM, the national Center for High Resolution Electron Microscopy vid Lund Universitet. Artikeln beskriver tekniska lösningar i systemet och deA new environmental transmission electron microscope has been installed in Lund in order to investigate the growth of III-V semiconductor nanowires by metal-organic chemical vapour deposition. We report here on the concepts behind the design of the facility and on details of the operation, and we refer to early results to highlight the new information that can be accessed from in situ studies. The

Based on multiphase field conception and integrated with the idea of vectorvalued phase field, a phase field model for typical allotropic transformation of solid solution is proposed. The model takes the non-uniform distribution of grain boundaries of parent phase and crystal orientation into account in proper way, as being illustrated by the simulation of austenite to ferrite transformation in lo

Context. Hot Jupiters (HJs) with close-by planetary companions are rare, with only a handful of them having been discovered so far. This could be due to their suggested dynamical histories, which lead to the possible ejection of other planets. TOI-2109 b is special in this regard because it is the HJ with the closest relative separation from its host star, being separated by less than 2.3 stellar

During fracture of membranes loading often produces buckles above and below the crack surface. This changes the stress state surrounding the crack-tip and stresses in the neighbourhood of the crack-tip posses a weaker singularity than r-1/2. As a result, fracture occurs when the crack-tip stress distribution is different as compared with that when buckling is artificially prevented.

Sda is a high-frequency carbohydrate histo-blood group antigen, GalNAcβ1-4(NeuAcα2-3)Galβ, implicated in pathogen invasion, cancer, xenotransplantation and transfusion medicine. Complete lack of this glycan epitope results in the Sd(a−) phenotype observed in 4% of individuals who may produce anti-Sda. A candidate gene (B4GALNT2), encoding a Sda-synthesizing β-1,4-N-acetylgalactosaminyltransferase

The 2013 reform of the Common Agricultural Policy (CAP) introduced compulsory ‘greening’ measures with the goal to mitigate environmental degradation caused by intensive agriculture. This paper aims to investigate how the implementation of the Ecological Focus Areas (EFA) obligation will affect regional agricultural development, the economic performance of farms and land use (including choices of

Objectives: Medial meniscal body extrusion ≥ 3 mm on MRI is often considered “pathologic.” The aims of this study were to (1) assess the adequacy of 3 mm as cut-off for “pathological” extrusion and (2) find an optimal cut-off for meniscal extrusion cross-sectionally associated with radiographic knee osteoarthritis, bone marrow lesions (BMLs), and cartilage damage. Methods: Nine hundred fifty-eight

Innovation plays an important role in organization survival and longevity. This is especially true in the retail industry; there is a growing acknowledgment of the role of innovation in retail practice, as maintaining the status quo might prove insufficient, especially for traditional retailers, in addressing the enormous challenges they are facing driven by technological developments and evolving

The low automation level of industrial manufacturing processes, in conjunction with the limited research in the field of object manipulation for placing tasks, rise the need for adaptive and accurate industrial robotic systems that can manipulate a variety of objects in an uncertain environment. We deal with those issues by providing insights into two modules of a skilled-based architecture, the SThe low automation level of industrial manufacturing processes, in conjunction with the limited research in the field of object manipulation for placing tasks, rise the need for adaptive and accurate industrial robotic systems that can manipulate a variety of objects in an uncertain environment.

INTRODUCTION: The postpartum period is part of an important process for mothers and fathers. A sense of security is central as it might influence a parent's journey towards becoming a successful parent. The aim was to determine factors affecting parents' postnatal sense of security (PPSS) before postpartum discharge from a hospital in Konya, Turkey.METHODS: A descriptive study was conducted. From

AIMS: To characterize changes in patterns of adolescent substance use in Sweden between 1988 and 2011, and to assess whether sex and psychosomatic problems were associated with substance use and whether these associations changed over time.DESIGN: Secondary analysis of repeated cross-sectional survey data. Survey data were collected eight times and analyzed as four cohorts (1988-91, 1995-98, 2002-

Does media history really start with a bang? More than just newspapers, television, and social networks, media are the means by which any information is communicated, from cosmic radiation traces to medieval church bells to modern identity documents. Cultures are held together as much by bookkeeping and records as they are by stories and myths.From Big Bang to Big Data is a long history of the med

The last 20 years have witnessed a marked increase in Swedish participation in major international UN-, EU- and/or NATO-led armed missions mandated according to Chapter VII of the UN Charter. This development reflects the new foreign and security priorities of Sweden in the wake of the end of the Cold War. Decisions on Swedish participation in such missions, however, cannot be taken without parlia

Expansions of innovation policies have been paralleled with an increase in the evaluations of such policies. Yet, there are few systematic evaluations of how such evaluations are conducted, by whom, and their overall conclusions. We analyze 110 evaluations of innovation policy in Sweden from 2005 to 2019. Our findings show that the majority of these evaluations are positive, about one-third are neExpansions of innovation policies have been paralleled with an increasein the evaluations of such policies.

Materials of ionic crystals are ubiquitous in industrial chemistry.For example, materials such as cerium dioixde (CeO2) are used in both self-cleaning ovens and to clean exhaust fumes from cars.Other materials, such as titanium dioixde (TiO2) has been used in the solar-cell industry.So-called garnets are used in several lasers.In common for all of these areas of application, is that they are depen
