Extended Producer Responsibility in East Asia: Approaches and lessons learnt from the management of waste electrical and electronic equipment

Environmental protection has become high in the policy agenda of East Asian countries by the end of the last century due to both internal and external stimuli. One of the main environmental issues is the management of solid waste. The concept of circular economy which encourages reduce, reuse, and recycling, i.e. 3Rs, together with the principle of Extended Producer Responsibility (EPR) has been p

Getting a Spot on the Street: : Street Vendors’ Access to Public Space in Bogotá, Colombia.

Is it truly the "end" of public space? This handbook presents evidence that the answer is "no". In cities in different parts of the world, people still use public space to pursue activities of their choice.The book is divided into seven sections. The first section presents three emerging types of public space. Each of the subsequent five sections focuses on a type of activity: recreation, commerce

Expression and activity of critical digestive enzymes during early larval development of the veined rapa whelk, Rapana venosa (Valenciennes, 1846)

Metamorphosis is a vital developmental event in the life cycle of molluscs and involves extensive morphological and physiological changes. Remodeling of the digestive system is suggested to occur anticipatorily to enable the larva to shift its diet (from filter feeding on microalgae to feeding on small bivalves) after metamorphosis. Changes in the profiles and activities of digestive enzymes, the

Environmental controls on marine ecosystem recovery following mass extinctions, with an example from the Early Triassic

The recovery of marine ecosystems following a mass extinction event involves an extended interval of increasing biotic diversity and ecosystem complexity. The pace of recovery may be controlled by intrinsic ecosystem or extrinsic environmental factors. Here, we present an analysis of changes in marine conditions following the end-Permian mass extinction with the objective of evaluating the role of

Environmental and physiological controls on diurnal and seasonal patterns of biogenic volatile organic compound emissions from five dominant woody species under field conditions

Biogenic volatile organic compounds (BVOCs) play essential roles in tropospheric chemistry, on both regional and global scales. The emissions of large quantities of species-specific BVOC depend not only on environmental (temperature, T; photosynthetically active radiation, PAR), but also physiological parameters (i.e. net photosynthetic rate, Pn; transpiration rate, Tr; stomatal conductance, gs an

To shake or not to shake : 13 C-based evidence on anaerobic methane oxidation in paddy soil

The anaerobic oxidation of methane (AOM) removes most of the biologically produced methane (CH 4 ) from marine ecosystems before it enters the atmosphere and thus mitigates greenhouse gas emissions. As compared to marine environments, surprisingly little is known about the role of AOM in terrestrial ecosystems. Particularly, how AOM controls the CH 4 budget of paddy soils is unexplored, partly

Temperature adaptation of soil microbial respiration in alpine, boreal and tropical soils : An application of the square root (Ratkowsky) model

Warming is expected to stimulate soil microbial respiration triggering a positive soil carbon-climate feedback loop while a consensus remains elusive regarding the magnitude of this feedback. This is partly due to our limited understanding of the temperature-adaptive response of soil microbial respiration, especially over broad climatic scales. We used the square root (Ratkowsky) model to calculat

Deciphering microbiomes dozens of meters under our feet and their edaphoclimatic and spatial drivers

Microbes inhabiting deep soil layers are known to be different from their counterpart in topsoil yet remain under investigation in terms of their structure, function, and how their diversity is shaped. The microbiome of deep soils (>1 m) is expected to be relatively stable and highly independent from climatic conditions. Much less is known, however, on how these microbial communities vary along cl

“We choose this CV because we choose diversity” : What do eye movements say about the choices recruiters make?

Introduction: A large body of research has established a consensus that racial discrimination in CV screening occurs and persists. Nevertheless, we still know very little about how recruiters look at the CV and how this is connected to the discriminatory patterns. This article examines the way recruiters view and select CVs and how they reason about their CV selection choices, as a first step in u

Applying labour law to micro, small and medium-sized enterprises: : A comparative study of 16 countries

The self-employed and micro, small and medium-sized enterprises (MSMEs) account for the greatest share of employment and make up the largest number of economic units worldwide. However, some countries exclude these economic units from certain obligations under their national labour laws in the belief that such obligations may impair enterprise growth and prosperity. This study considers the ways i

Adherence to the EAT-Lancet reference diet and risk of type 2 diabetes, metabolic dysfunction-associated steatotic liver disease, and their co-occurrence

Background and aims: The EAT-Lancet Commission proposed a healthy dietary pattern to prevent diet-related diseases while promoting planetary sustainability, but little is known regarding its associations with type 2 diabetes (T2D) and metabolic dysfunction-associated steatotic liver disease (MASLD), both of which are highly prevalent and frequently co-exist. We aimed to assess association of this

Associations of the EAT-Lancet reference diet with metabolic dysfunction-associated steatotic liver disease and its severity : a multi-cohort study

BACKGROUND AIMS: The EAT-Lancet Commission devised a globally sustainable dietary pattern to jointly promote human health and sustainability. However, the extent to which this diet supports metabolic dysfunction-associated steatotic liver disease (MASLD) has not yet been assessed. This study aimed to investigate the association between the EAT-Lancet diet and risk of MASLD and its severity.APPROAC

Comparison of hypoxia among four river-dominated ocean margins: The Changjiang (Yangtze), Mississippi, Pearl, and Rhone rivers

We examined the occurrence of seasonal hypoxia (O-2 < 2 mg l(-1)) in the bottom waters of four river-dominated ocean margins (off the Changjiang, Mississippi, Pearl and Rhone Rivers) and compared the processes leading to the depletion of oxygen. Consumption of oxygen in bottom waters is linked to biological oxygen demand fueled by organic matter from primary production in the nutrient-rich river p

Seger åt Tibet! : den tibetanska diasporan och den religiösa nationen

Popular Abstract in Swedish Tibet och den tibetanska buddhismen har i väst ofta kommit att användas som synonymer. Tidigt kom landets otillgänglighet och stängda dörrar mot omvärlden att utöva en stark lockelse för resande och religiösa sökare. De kom i många fall att betrakta landet och dess folk som bevarare av en kunskap och vishet som gått den övriga världen förlorad. Föreställningen om den rThis dissertation in anthropology of religion focuses on images of Tibet, among Westerners as well as among Tibetans. Based on approximately one year of fieldwork in the former British Hill station, it also deals with the politics of the Central Tibetan Administration (CTA) and some of its political and social implications for the exiled Tibetan youth living in Dharamsala, India. The Western perc

Probabilistic estimation of future emissions of isoprene and surface oxidant chemistry associated with land-use change in response to growing food needs

We quantify the impact of land-use change, determined by our growing demand for food and biofuel production, on isoprene emissions and subsequent atmospheric oxidant chemistry in 2015 and 2030, relative to 1990, ignoring compound climate change effects over that period. We estimate isoprene emissions from an ensemble (n = 1000) of land-use change realizations from 1990-2050, broadly guided by the

Polyamines are involved in the regulation of S phase and DNA synthesis

Popular Abstract in Swedish För att celler ska kunna växa och dela sig behöver de många olika ämnen, till exempel vitaminer, mineraler och polyaminer. Polyaminer finns i alla celler och de krävs för att cellerna ska kunna dela eller specialisera sig. Cellerna kan både själva tillverka polyaminer och ta upp dem från omgivningen. I mänskliga celler finns framför allt de tre polyaminerna putrescin, sOur research group has previously shown that treatment with the polyamine biosynthesis inhibitors a-difluoromethylornithine (DFMO) or amidinoindan-1-one 2´-amidinohydrazone (CGP 48664) inhibited S phase progression before any other cell cycle phase was affected. This study was undertaken to further investigate the role of polyamines in the regulation of S phase progression and DNA synthesis. I hav

Maternal and perinatal outcomes with COVID-19 : A systematic review of 108 pregnancies

INTRODUCTION: The pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has exposed vulnerable populations to an unprecedented global health crisis. The knowledge gained from previous human coronavirus outbreaks suggests that pregnant women and their fetuses are particularly susceptible to poor outcomes. The objective of this study was to summarize the clinical manife
