Leveraging multi-source satellite imagery for improving daily reservoir water storage and inflow estimation in a catchment hydrological model

Accurate reservoir dynamics, particularly water storage and inflow, are crucial for release decisions and operation rule assessments. However, the lack of sufficient monitoring data has hindered the accurate representation of reservoir behavior in hydrological models. While the increasing availability of satellite imagery provides unprecedented opportunities for dynamic reservoir monitoring, its p

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

Common Missense Variant in the Glucokinase Regulatory Protein Gene Is Associated With Increased Plasma Triglyceride and C-Reactive Protein but Lower Fasting Glucose Concentrations

OBJECTIVE-Using the genome-wide association approach, we recently identified the glucokinase regulatory protein gene (GCKR, rs780094) region as a novel quantitative trait locus for plasma triglyceride concentration in Europeans. Here, we sought to study the association of GCKR variants with metabolic phenotypes, including measures of glucose homeostasis, to evaluate the GCYR locus in samples of no

Expression of an LDL receptor allele with two different mutations (E256K and I402T)

AIMS: To investigate the disease causing event in patients with familial hypercholesterolaemia, carrying two mutations each, E256K in exon 6 and I402T in exon 9, of the gene encoding the low density lipoprotein (LDL) receptor. It was not known whether the mutations were positioned in cis or trans, or if they were each pathogenic separately or only when present together. METHODS: Polymerase chain r

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

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

A physiology-based Earth observation model indicates stagnation in the global gross primary production during recent decades

Earth observation-based estimates of global gross primary production (GPP) are essential for understanding the response of the terrestrial biosphere to climatic change and other anthropogenic forcing. In this study, we attempt an ecosystem-level physiological approach of estimating GPP using an asymptotic light response function (LRF) between GPP and incoming photosynthetically active radiation (P

A comprehensive quantification of global nitrous oxide sources and sinks

Nitrous oxide (N2O), like carbon dioxide, is a long-lived greenhouse gas that accumulates in the atmosphere. Over the past 150 years, increasing atmospheric N2O concentrations have contributed to stratospheric ozone depletion1 and climate change2, with the current rate of increase estimated at 2 per cent per decade. Existing national inventories do not provide a full picture of N2O emissions, owin

Referential iconicity in music and speech within and across sensory modalities

Musical meaning is multifaceted: both highly sensory and yet often abstract, able to cross cultural boundaries and yet embedded in specific traditions. For the most part it is not denotational (Monelle, 1991). Nevertheless, in “programmatic music”, musical themes are intended to refer to worldly objects and events on the basis of iconic (and indexical) grounds. Such non-arbitrariness of the sound-

Genredigering - ett nytt sätt att diskriminera på?

Efter att det blev känt att en kinesisk forskare hade genredigerat två embryon, blev genredigering ett mycket omtalat ämne runt om i världen. Händelsen ledde till stora diskussioner på olika nivåer och ledde till många rekommendationer kring de etiska avgränsningar som bör göras. Vetenskapen går ständigt framåt och därför är det av betydelse att göra en omfattande analys av hur rättsläget inom g

Policies - A Lever for Industry Transformation

Sustainability is a megatrend affecting companies’ strategic development process in many industries, including the dairy industry. The concerns on environmental issues in combination with other societal demands have initiated an industry transformation towards dairy alternatives. While the magnitude remains uncertain, policies are significant in accelerating or inhibiting the shift. However, exist

Palynostratigraphy of the Cretaceous-Paleogene mass-extinction interval of the Southern Hemisphere

The palynofloral changes around the Cretaceous-Paleogene (K-Pg) mass extinction event reveal the fine details of vegetation response to a global environmental crisis-in this case an asteroid impact in Mexico 65.5 million years ago. Due to the extinction of several plant taxa at the K-Pg boundary, palynostratigraphy is a prime tool for localizing the Cretaceous-Paleogene boundary in non-marine succ

There are few studies on associations between respiratory health and allergens, fungal and bacterial compounds in schools in tropical countries. The aim was to study associations between respiratory symptoms in pupils and ethnicity, chemical microbial markers, allergens and fungal DNA in settled dust in schools in Malaysia. Totally 462 pupils (96%) from 8 randomly selected secondary schools in Joh

Effektivisering av snöröjning

Entrepreneurs have difficulties in performing maintenance activities due to the increasing intensity of train services and failing infrastructure. Annually, the state loses billions of SEK due to delays caused by failures in infrastructure or maintenance not performed on time. The largest amounts of delays occur during winter time, when our infrastructure cannot cope with the climate as it is expo

Comparison of historical medical spending patterns among the BRICS and G7

OBJECTIVE: The past few decades have been marked by a bold increase in national health spending across the globe. Rather successful health reforms in leading emerging markets such as BRICS reveal a reshaping of their medical care-related expenditures. There is a scarcity of evidence explaining differences in long-term medical spending patterns between top ranked G7 traditional welfare economies an
