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
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 (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
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
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
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
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
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-
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
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
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
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
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.

Under första veckan av april 2018 genomfördes 1000 telefonintervjuer på temat allmänhetens atti- tyd till användandet av bevakningskameror på gator och torg. 90% av allmänheten svarade positivt när de ställdes frågan ”Vad tycker du om bevakningskameror på allmän plats?” uppdelat på 49% som ställde sig mycket positiva och 41% som ställde sig ganska positiva. Vidare ansåg 72% av de tillfrågade att d

Are entrepreneurial cultures stable over time? In this paper, we use historicalmeasures of the outgrowth of entrepreneurial culture in China and test whether these correlate with entrepreneurial activities today. We employ provincial panel data from China documenting the regional distribution of entrepreneurial activities during the Ming Dynasty (1368–1644) and the Qing Dynasty (1644–1912) and pri
