Chamber measurements of trace gas fluxes between the land surface and the atmosphere have been conducted for almost a century. Different chamber techniques, including static and dynamic, have been used with varying degrees of success in estimating greenhouse gases (CO2, CH4, N2O) fluxes. However, all of these have certain disadvantages which have either prevented them from providing an adequate es

Historical wage studies have never been able to truly or accurately address the changes in the working year. Real wages have almost always been based on the wages of unskilled and casual laborers, typically paid by the day. Their annual incomes are not clear or obvious – the income is directly dependent on how many days they work. Implicitly the literature has assumed that the number of days worke

Purpose: This study investigates the relationship between sick-listed patients’ return to work (RTW) expectancy and how they perceive that their physicians evaluate their ability and volition for RTW.Methods: Hierarchical logistic regression controlling for sociodemographic factors and pain characteristics was carried out on cross-sectional data from 205 participants (mean age= 47.24±9.66 years, 8

High temperatures generated in machining are known to facilitate oxidation wear. A controlled atmosphere chamber was developed to investigate the effects of oxygen on tool wear and high speed machining tests were conducted on air and in argon. Cemented carbide, cermet and cubic boron nitride tooling was used on alloyed steel, hardened tool steel and superalloy Alloy 718. Machining in argon resulte

Results of the study of cutting speed and tool wear influence on the vibrations and their nature during machining superalloy Inconel 718 with low cBN content (cBN-L) and binderless pcBN (bcBN) tools are presented. Cutting speed was varied from 2 to 14 m/sec while other cutting conditions were constant. The process evolution was studied with the wavelet transform of tool acceleration spectra. Behav

Residual stresses induced by machining operations can be critical for the performance and lifetime of the machined components. Tis paper investigated the influence of cutting conditions, including the use of cutting fluid, cutting speed and tool flank wear, on the residual stresses in high speed turning of Inconel 718 alloy. X-ray diffraction measurements revealed characteristic residual stress di

The use of a polar diagram method for describing and evaluating the machinability of Inconel 718 was explored. Five key parameters of the work material, representing the mechanical and physical properties which have strongest influence on its machinability, were employed in the diagrams. These five parameters were integrated into a single polar diagram, used to describe the machinability of Incone

This work presents a diagraph method for the description and predication of the potential machinability of work materials. In the method, a radar chart with five axes was used to examine the machinability of different work materials and each axis representing a behavior or property, i.e. abrasiveness or hardness of workpiece material by grading the 5 different machinability properties. Such charts

The nanoindentation in the continuous stiffness measurement mode was used to investigate the onset of plasticity at the nanodeformation of cubic boron nitride (cBN). This technique allows us to reveal an elastic-plastic transition in the contact and to measure the yield strength of cBN at the nanoscale. An abrupt elastoplastic transition (a pop-in) was observed in the (111) cBN single crystal as a

BACKGROUND: The Global Burden of Disease (GBD) Study provides estimates of deaths, years of life lost (YLL), years of life lived with disability (YLD), and disability-adjusted life years (DALYs) due to 249 causes of death, 315 diseases and injuries, and 79 behavioral, environmental, occupational, and metabolic risk factors in 195 countries, territories, and regions by sex and 20 age categories in

Migrant integration is a long drawn out process requiring synergies with various dimensions of life, rhyming with those of the host country. In this paper, we attempt to deconstruct the digital narratives of migrant to explore how they may lead to a meaningful assessment of their acculturation and consequent integration in their host societies’. Drawing on acculturation theory as a lens, we argue

This paper conducts an inductive case study to understand how the opportunity creation process leads to integration. It examines four cases of immigrant entrepreneurs of Cameroonian, Lebanese, Mexican and Assyrian origins who founded their businesses in Sweden. The study relies on process-oriented theory building and develops an inductive model of integration as an opportunity creation process. Th

This paper adopts an inductive case study to examine the role of family resilience in the immigrants’ opportunity creation process. We employ family resilience (Walsh, 2002) and the opportunity creation process (Alvarez and Barney, 2007). We conducted an inductive case study on four cases of immigrant entrepreneurs who established businesses in Sweden and who have their origins in Lebanon and Syri

BACKGROUND AND AIMS: Gambling disorder (GD) appears to be an independent risk factor for suicide, and all-cause mortality has been sparsely studied in patients with GD. This study aims to explore mortality and suicide rates in individuals with GD compared to the general population as well as explore risk factors associated with all-cause mortality and suicide mortality. METHODS: This is a nationwi

Background Prolonged angiogenesis inhibition may improve treatment outcome in metastatic colorectal cancer (mCRC) patients. However, due to the complexity of the angiogenic pathways there is a lack of valid predictive biomarkers for anti-angiogenic agents. Here, we describe and optimize a procedure for simultaneous dynamic profiling of multiple angiogenesis related proteins in patient serum to exp

Many proteins consist of folded domains connected by regions with higher flexibility. The details of the resulting conformational ensemble play a central role in controlling interactions between domains and with binding partners. Small-Angle Scattering (SAS) is well-suited to study the conformational states adopted by proteins in solution. However, analysis is complicated by the limited informatio

The problem of time-delays estimation of backscattered echoes from underwater targets is presented using a sparse reconstruction framework employing an integrated dictionary. To achieve high resolution, the used dictionary is usually defined over a finely spaced grid over the region of interest. Such a procedure may result in problems of being computational cumbersome or suffering from basis misma
