Post-Traumatic Growth during COVID-19 : The Role of Perceived Social Support, Personality, and Coping Strategies

Although many studies on mental health have been conducted among various populations during the COVID-19 pandemic, few studies have focused on post-traumatic growth (PTG) in the general population. The current study aimed to explore whether perceived social support, personality, and coping strategies are associated with PTG in the COVID-19 pandemic period. The study also investigated whether copin

A Vector Field Approach to Estimating Environmental Exposure Using Human Activity Data

Environmental exposure of people plays an important role in assessing the quality of human life. The most existing methods that estimate the environmental exposure either focus on the individual level or do not consider human mobility. This paper adopts a vector field generated from the observed locations of human activities to model the environmental exposure at the population level. An improved

The out of Africa hypothesis and the ancestry of recent humans : Cherchez la femme (et l'homme)

The out of Africa hypothesis (OOAH) has been a mainstay in the discussion of human evolution since its presentation in the 1980's. However, recent advances in palaeontology and molecular genetics have made it possible to examine the hypothesis in a manner that was inconceivable at the time of its proposal. The palaeontological progress relates to early Homo finds in the Caucasus, Denisova finds in

Global imbalances in climate protection, leadership ambitions and EU climate change law

The message conveyed by the Intergovernmental Panel on Climate Change (IPCC) is clear: the global climate crisis has arrived (e.g., IPCC, 2007, 2014). It is commonly understood that responding to this crisis requires coordinated actions at a global level (Weischer et al., 2012, p. 117; Kulovesi, 2012, p. 193). Attempts to slow down the increase in global temperature, as well as to organize and exc

Multiplex genome editing eliminates the Warburg Effect without impacting growth rate in mammalian cells

The Warburg effect is ubiquitous in proliferative mammalian cells, including cancer cells, but poses challenges for biopharmaceutical production, as lactate accumulation inhibits cell growth and protein production. Previous efforts to eliminate lactate production via knockout have failed in mammalian bioprocessing since lactate dehydrogenase has proven essential. However, here we eliminated the Wa

Towards healthcare access equality : Understanding spatial accessibility to healthcare services for wheelchair users

Considering that the number of wheelchair users is on the rise at the global level due to population aging, it is crucial to secure their rights to have adequate access to healthcare services. Spatial accessibility to healthcare services has been well recognized to influence people's health. However, research on healthcare accessibility of wheelchair users is scarce. This study proposes a barrier-

Modification of the activated sludge model for chemical dosage

Full-scale experiments have been carried out to adapt the activated sludge model ASM2d to include the influence of metal dosage (Fe3+ and Al3+) for phosphorus removal. Phosphorus removal rates, nitrification rates, as well as pH and sludge settling performance, were evaluated as functions of the metal dosages. Furthermore, models relating certain parameters to the dosage of chemicals have been der

Proxy global assessment of land degradation

Land degradation is always With Lis but its causes, extent and severity are contested. We define land degradation as a long-term decline in ecosystem function and productivity, Which may be assessed using lone-term, remotely sensed normalized difference vegetation index (NDVI) data. Deviation from the norm may serve as a proxy assessment of land degradation and improvement - if other factors that

Renaissance 1.5

Projektet Renässans 1.5 utgår ifrån det faktum att det i den traditionella produktutvecklingsprocessen normalt krävs flera iterationer i processens olika faser innan man kan nå en acceptabel kompromiss mellan estetiska krav och konstruktions- och tillverkningskrav. Den snabba utvecklingen inom optimeringsteknik och kunskapsbaserad konstruktion gör det möjligt att integrera ett datorbaserat formgivThe Renaissance 1.5 project was based on the observation that in traditional product development, several iterations are needed to obtain a compromise between engineering, manufacturing constraints and aesthetics. The rapid advances in optimisation methods and in knowledge-based engineering (KBE) make it possible to integrate engineering and manufacturing constraints in a computer-based industrial

Short-term prediction of influent flow rate and ammonia concentration in municipal wastewater treatment plants

The prediction of the influent load is of great importance for the improvement of the control system to a large wastewater treatment plant. A systematic data analysis method is presented in this paper in order to estimate and predict the periodicity of the influent flow rate and ammonia (NH3) concentrations: 1) data filtering using wavelet decomposition and reconstruction; 2) typical cycle identif

Mapping the narrative positions of new political groups under the UNFCCC

Since 2009, the United Nations Framework Convention on Climate Change (UNFCCC) regime has seen the emergence of several new political groups. This article analyses how the new political groups are positioning themselves in relation to the key UNFCCC principles (the North–South divide and ‘common but differentiated responsibility and respective capabilities’, CBDR/ RC). Drawing on original data, in

Intracellular sorting of galectin-8 based on carbohydrate fine specificity

Galectin-8 has two carbohydrate recognition domains (CRDs), both of which bind beta-galactosides, but have different. ne specificity for larger saccharides. Previously we found that both CRDs were needed for efficient cell surface binding and signaling by soluble galectin-8, but unexpectedly binding of the N-CRD to its best ligands, alpha 2-3-sialylated galactosides, was not needed. In search for

Quinoline-triazole half-sandwich iridium(iii) complexes : Synthesis, antiplasmodial activity and preliminary transfer hydrogenation studies

Iridium(iii) half-sandwich complexes containing 7-chloroquinoline-1,2,3-triazole hybrid ligands were synthesised and their inhibitory activities evaluated against the Plasmodium falciparum malaria parasite. Supporting computational analysis revealed that metal coordination to the quinoline nitrogen occurs first, forming a kinetic product that, upon heating over time, forms a more stable cyclometal

Molecular evolution of coxsackievirus A24v in Cuba over 23-years, 1986–2009

Coxsackievirus A24 variant (CVA24v) is a major causative agent of acute hemorrhagic conjunctivitis outbreaks worldwide, yet the evolutionary and transmission dynamics of the virus remain unclear. To address this, we analyzed and compared the 3C and partial VP1 gene regions of CVA24v isolates obtained from five outbreaks in Cuba between 1986 and 2009 and strains isolated worldwide. Here we show tha

Greening of the Earth and its drivers

Global environmental change is rapidly altering the dynamics of terrestrial vegetation, with consequences for the functioning of the Earth system and provision of ecosystem services. Yet how global vegetation is responding to the changing environment is not well established. Here we use three long-term satellite leaf area index (LAI) records and ten global ecosystem models to investigate four key
