Determining the Accuracy and Reliability of Indirect Calorimeters Utilizing the Methanol Combustion Technique

Background: Several indirect calorimetry (IC) instruments are commercially available, but comparative validity and reliability data are lacking. Existing data are limited by inconsistencies in protocols, subject characteristics, or single-instrument validation comparisons. The aim of this study was to compare accuracy and reliability of metabolic carts using methanol combustion as the cross-labora

Tuning the morphology of self-assisted GaP nanowires

Patterned arrays of self-assisted GaP nanowires (NWs) were grown on a Si substrate by gas source molecular beam epitaxy using various V/III flux ratios from 1-6, and various pitches from 360-1000 nm. As the V/III flux ratio was increased from 1-6, the NWs showed a change in morphology from outward tapering to straight, and eventually to inward tapering. The morphologies of the self-assisted GaP NW

Armed forces in disaster response : Problems and perspectives on disaster governance in India

Abstract: This chapter looks at the challenges of disaster governance in India. It highlights the problems of engaging the Armed Forces as the responder to disasters given the prevalent sociological dynamics within the communities. The Armed Forces in India have successfully responded to several catastrophes such as the Gujarat earthquake, the Indian Ocean tsunami, the Kashmir earthquake and the m

Double Compression Expansion Engine Concepts : Efficiency Analysis over a Load Range

Double Compression Expansion Engine (DCEE) concepts are split-cycle concepts where the main target is to improve brake efficiency. Previous simulations work [1] suggests these concepts has a potential to significantly improve brake efficiency relative to contemporary engines. However, a high peak efficiency alone might be of limited value. This is because a vehicle must be able to operate in diffe

Feedback in Small Systems -A Stochastic Thermodynamic Perspective

Recent advances in nanotechnology and the accompanying development oftechniques that operate and manipulate systems on the micro- and nanometer scale have driven the development of stochastic thermodynamics. This isa theory that can describe small systems far from equilibrium, where the fluctuations are of the same order of magnitude as the mean values. Stochasticthermodynamics can be used to prov

The theology of the land in Jewish-Christian relations and its role in misunderstandings between jews and Christians

Without sufficient knowledge of the painful history of Jewish-Christian apologetics and polemics, which have their origins in late antiquity and continued on into the medieval period, it is easy to fail to recognise the complexities of current Christian approaches to the Land that is now known as Israel and/or Palestine. Jesper Svartvik here examines the interplay of theology and politics, and, in

Cylinder Pressure Based Virtual Sensor for In-Cycle Pilot Mass Estimation

In this paper, a virtual sensor for the estimation of the injected pilot mass in-cycle is proposed. The method provides an early estimation of the pilot mass before its combustion is finished. Furthermore, the virtual sensor can also estimate pilot masses when its combustion is incomplete. The pilot mass estimation is conducted by comparing the calculated heat release from in-cylinder pressure mea

The Potential of SNCR Based NOx Reduction in a Double Compression Expansion Engine

Selective Non-Catalytic Reduction (SNCR), used to reduce the emissions of nitrogen oxides (NOx), has been a well-established technology in the power plant industry for several decades. The SNCR technique is an aftertreatment strategy based on thermal reduction of NOx at high temperatures. In the compression ignition engine application, the technology has not been applicable due to low exhaust temp

Inter-phase charge and energy transfer in Ruddlesden-Popper 2D perovskites : Critical role of the spacing cations

Photo-generated charge carrier dynamics in Ruddlesden-Popper 2D perovskites with linear (n-BA) and branched (iso-BA) butylamine as spacing cations have been studied by using transient absorption and time-resolved photoluminescence spectroscopies. Both n-BA and iso-BA perovskites consist of mixed-phase 2D quantum wells with various layer thicknesses, where the photo-generated charges undergo inter-

Between Values and the World : Studies in second-order value theory

Value is an inescapable part of the human experience and what life must be like for a conscious and feeling person. Philosophical questions about value are therefore naturally invited: What sort of thing would value be if it were part of the furniture of the world? How should we understand the relations that value is thought to stand in to other things? In a broad sense, these are formal questions

A Swedish national adoption study of risk of irritable bowel syndrome (IBS)

Objectives: Irritable bowel syndrome (IBS) clusters in families, but the familial risk of IBS has not been determined in adoptees. Studying adoptees and their biological and adoptive parents is a strong study design for separating genetic from environmental causes of familial clustering. This nationwide study aimed to separate the biological (genetic) and familial environmental contribution to the

Association of irritable bowel syndrome and venous thromboembolism

OBJECTIVE: Inflammatory bowel disease (IBD) is associated with venous thromboembolism (VTE). Whether functional gastrointestinal disorders, such as irritable bowel syndrome (IBS), are associated with VTE has not been determined. This nationwide study aimed to determine the risk of VTE in IBS outpatients in primary and specialist care.DESIGN: We performed two matched case-control studies. Cases (n

BCAT1 restricts αKG levels in AML stem cells leading to IDHmut-like DNA hypermethylation

The branched-chain amino acid (BCAA) pathway and high levels of BCAA transaminase 1 (BCAT1) have recently been associated with aggressiveness in several cancer entities. However, the mechanistic role of BCAT1 in this process remains largely uncertain. Here, by performing high-resolution proteomic analysis of human acute myeloid leukaemia (AML) stem-cell and non-stem-cell populations, we find the B

The perception of surveillance cameras (CCTV) and privacy among the general public in Sweden, August 2017

During the second week of August, 1,000 Swedes were asked via telephone about their opinions on the use of security cameras in public spaces. Ninety percent of the public were positive when asked the question “What do you think about surveillance cameras in public spaces?” – 49% stat- ing that they are “very positive” and 41% “quite positive”. Furthermore, 72% of the respondents stated that there During the second week of August, 1,000 Swedes were asked via telephone about their opinions on the use of security cameras in public spaces.
