This paper is an attempt to evaluate the impact of the oil refinery industry on water resources worldwide from the point of view of sustainable development (SD). The local laws, reports from the industry and environmental agencies, conditions of the final disposal system were analysed. Key aspects, such as existing approaches for treatment systems, quality of treated wastewater, and ways to assure

We prove a sharp Lipschitz bound for isotropic matrix functions in terms of the Lipschitz constant for the underlying vector field.

The notion of authenticity arises in tourism research in two ways: In theory, as a contentious, complicated and disputed construct; empirically, as a recurrent theme in accounts of tourist experiences of place and culture and as a quality of tourists' experiences. This duality creates tension over the utility of authenticity in research and theory. We review recent literature on authenticity withi

This study seeks a better understanding of possible pathophysiological mechanisms associated with cognitive impairment and dementia in Parkinson's disease using structural and functional MRI. We investigated resting-state functional connectivity of important subdivisions of the caudate nucleus, putamen and thalamus, and also how the morphology of these structures are impacted in the disorder. We f

Raman spectroscopy is widely used for characterization of carbon-based mate- rials including light-absorbing carbonaceous (LAC) matter. However, informa- tion on polarization properties of these materials are generally lacking, and often the polarization characteristics of experiments are not presented in the literature thereby giving uncertainty to presented data. In this work, the polari- zation

Low impact falls to the side are the main cause of hip fractures in elderly. Finite element (FE) models of the proximal femur may help in the assessment of patients at high risk for a hip fracture. However, extensive validation is essential before these models can be used in a clinical setting. This study aims to use strain measurements from bilateral digital image correlation to validate an FE mo

Cancer is a complex disease with various genetic and epigenetic driving factors. Cancer cells form a favored microenvironment to sustain their uncontrolled behavior leading to abnormal growth. With standard treatment including chemotherapy, relapse risk is high due to the resistance that cancer cells can develop against chemotherapy agents. Immuno-oncological therapeutics, as alternatives, have sh

BACKGROUND AND AIMS: The relationship between inflammation and lipid metabolism is complex and bidirectional. Lymphocyte-driven inflammation has been shown to modulate both atherosclerotic plaque development and cholesterol levels, but the mechanisms are incompletely understood.METHODS: The cardiometabolic effects of IL-2Rβγ signalling in atherosclerotic Apoe-/- mice were investigated by treatment

It is commonly argued that crises open up a window of opportunity to implement policies that otherwise would not have the necessary political backing. The argument goes that the political cost of economic and social reforms declines as crises unravel structural problems that need to be urgently rectified and the public is more willing to bear the pains associated with such reforms. This paper cast

Few empirical studies have investigated career‐related incentives for party membership, including for young party members. Through the lens of rational choice, we ask what career‐related incentives young and active party members consider when calculating costs and benefits of party membership. We argue for a broad understanding of career‐related incentives, including careers outside party politics

The current fossil-based economy must be transformed into a bio-based circular economy. A cornerstone of this transformation is the conversion of pulp and paper mills into lignocellulosic biorefineries that allow not only the production of pulp, paper, and electricity, but also novel biochemicals. Highly selective, electrifiable, and low-energy-consuming separation technologies will be key in the

Representing mutually exclusive alternatives (“A or B”), ruling out one or multiple alternatives (“not A”), and thereby concluding that the remaining alternative must be true (“therefore B”).

The quality and performance of products are particularly important in sectors such as research facilities and in the nuclear, military and space industries. These sectors make use of high-performance materials that are uncommon in other contexts and therefore place high requirements on personnel, machines and tools. While tool manufacturers have readily available tool selection guides and cutting
