We report on the study of fast-neutron background for the BIFROST spectrometer at ESS. We investigate the effect of background radiation induced by the interaction of fast neutrons from the source with the material of the neutron guide and devise a reasonable fast, thermal/cold neutron shielding solution for the current guide geometry using McStas and MCNPX. We investigate the effectiveness of the
Reduction of trans-[Pt(CN)(4)Cl-2](2-) by [Pt(NH3)(4)](2+) and [Pt(en)(2)](2+) was studied at 25 degrees C in the range 0 less than or equal to [Cl-] less than or equal to 0.4 M by use of stopped-flow spectrophotometry. The stoichiometry [Pt(IV)]:[Pt(II)] is 1:1. Rapid-scan spectra show clear-cut isosbestic points, indicating that no reaction intermediates are accumulated to a significant amount.
This study explores the application of spatial modelling techniques to generate susceptibility maps for a neglected zoonotic disease, visceral leishmaniasis (VL), in an endemic area in southern Caucasus that includes Iran, Armenia and Azerbaijan. The social and physical environment of southern Caucasus has been mainly characterized by the presence of several factors that are strongly associated wi
The income velocity of money in several countries such as Sweden, the United States and Great Britain, displays a U-shaped pattern for the last one hundred years. This paper proposes an explanation of this secular behavior based on an extension of Wicksell’s work on velocity emphasizing the influence of institutional changes. The secular fall in velocity in the last half of the 19th century and th
Molecular imprinting is the technology of creating artificial recognition sites in polymeric matrices which are complementary to the template in their size, shape and spatial arrangement of the functional groups. Molecularly imprinted polymers (MIPs) and their incorporation with various transducer platforms are among the most promising approaches for detection of several analytes. There are a vari
Desert vernacular architecture is a product of a sustainable building cycle. Desert local inhabitants inherited the traditional way of building from their ancestors developed and then transferred knowledge from one generation to another. This building and cultural cycle is about to disappear in many desert vernacular settlements of the world. Global ambitions and socio-economic developments are so
While pure deliberation has still not been found online, the field of online deliberation research is blossoming. Born out of the “frustrations and possibilities” of the 1990s, a current theme in the field is to re-link deliberative theory with empirical political science. The aim of this systematic literature review is to sort out and examine important features of this development; to identify an
Rhombomys opimus (R. opimus), a social rodent, is the main reservoir host for zoonotic cutaneous leishmaniasis (ZCL) in most parts of the Middle East and central Asia. The difficulties in monitoring rodent population patterns have hindered the effective application of preventive measures of ZCL. This study presents a spatially explicit agent-based simulation model of R. opimus behaviors that is in
Evacuation models can be reliably used if they are sufficiently validated for the application in question (e.g. Fire Safety Engineering). To be useful, an evacuation model should therefore be an accurate enough representation of the real-world behaviour of evacuees. The scope of this work was to determine how accurately the model crowd:it (making use of the Optimal Steps Model) provides a represen
I detta arbete har en Minimum viable product (MVP) för en applikation utvecklats, som gör det säkrare att avveckla och ta bort endpoints för ett REST API. Tidigare arbete har visat att hanteringen av avvecklingen av endpoints i REST API:er är ett problem, där REST API:er inte följer protokoll för avveckling och borttagning. Applikationen är gjord för att tillhandahålla ett enkelt sätt att övervakaIn this thesis - a Minimum viable product (MVP) for an application aimed at making deprecation and removal of REST API endpoints safer - was developed. Previous work has shown that handling deprecations and removal of endpoints in REST APIs is a problem, with REST APIs not following deprecation-removal protocols nor giving the API consumers the information needed to properly update their software.
Understanding the sustainability concept: According to the UN World Commission on Environment,(Borowy, 2013) it is the balance between environment, economy, and equity. The development meets the needs of the present without compromising the ability of future generations to meet their own needs (Rauschmayer et al., 2012). Sustainability is integration of the environmental health, social equity, and
This report describes the research, conclusions, and result of my Master Degree thesis project in Industrial Design at Lund University. The thesis was completed during the spring semester of 2018. The work was carried out in collaboration with Trimble Geospatial in Danderyd, Sweden. The main purpose of this thesis was to explore the future methods of working with geospatial instruments - s
Microfluidic devices have so far not seen widespread use, even though they could potentially be cheaper, better and faster than traditional methods. A possible reason for this is the lack of a middle step between one-of-a-kind experimental devices and cheap mass produced devices. With ongoing improvements in resolution it is starting to look possible that 3D-printing will fill this role. This the
Purpose: To explore why brands lose control over their identity due to internal actions or lack of actions when needed. The paper examines the key elements brands should focus on internally to prevent brand identity erosion which can negatively impact brand performance. Methodology: This paper explains the relevance of brand identity by a literature review and further builds on fundamental causes
