Migrant Labor Markets in Russia and Turkey
During our ethnographic fieldwork in Istanbul, we spent most of our time wandering the streets of the Kumkapi neighborhood, where it is possible to spot hundreds of Uzbek migrants who reside and/or work there.
The association between peripheral arterial disease and risk for hip fractures in elderly men is not explained by low hip bone mineral density. Results from the MrOS Sweden study
Summary: In this prospective study in Swedish elderly men, PAD based on an ABI < 0.9 was associated with an increased risk of hip fracture, independent of age and hip BMD. However, after further adjustments for comorbidity, medications, physical function, and socioeconomic factors, the association diminished and was no longer statistically significant. Introduction: To examine if peripheral arteri
Internet-delivered approach-avoidance conflict task shows temporal stability and relation to trait anxiety
Excessive avoidance causes functional impairment and maintains anxiety disorders. In the laboratory, approach-avoidance conflict tasks (AACT) can be used to study approach-avoidance behavior in mixed outcome situations (i.e., the same behavior entails both aversive and rewarding consequences). We tested the feasibility of a novel, internet-delivered AACT (iAACT) by conceptually replicating results
UNCRITICAL CONSTITUTION : CCO, Critique and Neoliberal Capitalism
This chapter is an attempt to rectify one of the main shortfalls of the constitutive approach of communication (CCO): the absence of neoliberal capitalism in its conception of both communication and organizations. Any theory of the social must at least consider the current social order at hand, which we refer to as neoliberal capitalism. Building on the theoretical premise that communication is a
CFD modeling and comparison of bioreactor performance across scales at Alvotech
At Alvotech, bioreactors are used for the production of biosimilars. During the production scale-up process, issues can arise at larger scale that are difficult to predict based on physical experiments. Using CFD, two 3D bioreactor models of different scales have been created, namely the 15L HyPerformaTM Glass Bioreactor and 250L HyPerformaTM Single-Use Bioreactor, both manufactured by Thermo FishDuring bioreactor scale-up, unexpected failures become more prevalent due to the increase in volume. A comparison of mixing performance was thus made using computational modeling for two bioreactors at different scales. At the biopharmaceutical company Alvotech, bioreactors are used at different scales for producing biological medicines known as biosimilars. Bioreactors are vessels containing a m
Strongly reduced optical absorption efficiency of soot with addition of potassium chloride in sooting premixed flames
Optical properties of soot have been investigated with and without potassium chloride (KCl) salt added to the soot formation process in a premixed ethylene/air flame. A strong decrease in optical absorption efficiency of the soot was observed with increasing amounts of KCl added to the fuel based on the method of fluence curve analysis using laser-induced incandescence (LII). To understand the rea
Unravelling the origin of the common wall lizards (Podarcis muralis) in south-eastern Europe using mitochondrial evidence
The origin of the common wall lizards (Podarcis muralis) populations in south-eastern Europe (namely in Bulgaria and Romania), representing the north-eastern range border of this species, was addressed using mitochondrial DNA. We compared cytochrome b sequences from Bulgaria and Romania with those from the contiguous range in Central Europe that are available from previous studies. We recorded fiv
Sub-cycle high-order nonlinearities in a terahertz quantum cascade laser
Ultrafast electron dynamics in quantum cascade lasers hold enormous potential for the implementation of intense, compact mode-locked terahertz sources, squeezed terahertz light, frequency mixers, and comb-based metrology systems. Yet the important sub-cycle dynamics have been notoriously difficult to access in operational terahertz quantum cascade lasers. Here we show the first field-resolved two-
Deep profiling of multiple ischemic lesions in a large, multi-center cohort: Frequency, spatial distribution, and associations to clinical characteristics
Background purpose: A substantial number of patients with acute ischemic stroke (AIS) experience multiple acute lesions (MAL). We here aimed to scrutinize MAL in a large radiologically deep-phenotyped cohort. Materials and methods: Analyses relied upon imaging and clinical data from the international MRI-GENIE study. Imaging data comprised both Fluid-attenuated inversion recovery (FLAIR) for white
On negative eigenvalues of the spectral problem for water waves of highest amplitude
We consider a spectral problem associated with steady water waves of extreme form on the free surface of a rotational flow. It is proved that the spectrum of this problem contains arbitrary large negative eigenvalues and they are simple. Moreover, the asymptotics of such eigenvalues is obtained.
Heterogeneity of management practices surrounding operable gallbladder cancer – results of the OMEGA-S international HPB surgical survey
Background: Gallbladder cancer (GBC) is an aggressive, uncommon malignancy, with variation in operative approaches adopted across centres and few large-scale studies to guide practice. We aimed to identify the extent of heterogeneity in GBC internationally to better inform the need for future multicentre studies. Methods: A 34-question online survey was disseminated to members of the European-Afri

Exogenous shocks, Covid 19 and firms' ability to learn, adapt and evolve
In the context of the exponential growth of data, the Covid 19 pandemic and the need for quick adaptation faced by companies, as well as by society at large, the concept of organisational learning is flourishing and becoming an even more critical component of organisational survival and growth. This study applies a socio-technical lens to shed light on the organisational learning processes taking
Vegetation change on mountaintops in northern Sweden : Stable vascular-plant but reordering of lichen and bryophyte communities
Alpine ecosystems harbor remarkably diverse and distinct plant communities that are characteristically limited to harsh, and cold climatic conditions. As a result of thermal limitation to species occurrence, mountainous ecosystems are considered to be particularly sensitive to climate change. Our understanding of the impact of climate change is mainly based on vascular plants however, whereas cryp
LES/FGM investigation of ignition and flame structure in a gasoline partially premixed combustion engine
This paper presents a joint numerical and experimental study of the ignition process and flame structures in a gasoline partially premixed combustion (PPC) engine. The numerical simulation is based on a five-dimension Flamelet-Generated Manifold (5D-FGM) tabulation approach and large eddy simulation (LES). The spray and combustion process in an optical PPC engine fueled with a primary reference fu

Immune gene expression in the mosquito vector Culex quinquefasciatus during an avian malaria infection
Plasmodium relictum is the most widespread avian malaria parasite in the world. It is listed as one of the 100 most dangerous invasive species, having been responsible for the extinction of several endemic bird species, and the near-demise of several others. Here we present the first transcriptomic study focused on the effect of P. relictum on the immune system of its vector (the mosquito Culex qu
Evolution of residual stress when turning a fillet radius in stainless steel
Most studies have been carried out to investigate the surface integrity induced by metal cutting process. However, the previous studies are limited to a longitudinal turning or orthogonal cutting operations and the residual stresses generated in a fillet radius have been ignored. This study uses a combination of experiments and numerical simulations to study the evolution of cutting forces, temper
