The Grande de Tárcoles River in Costa Rica is one of the most polluted and degraded river basins in Central America. At the same time Costa Rica is a country internationally recognized for progressive environmental management. At least on paper, the country fosters sustainable river management in the form of integrated water resources management (IWRM). In the specific case of the Grande de Tárcol
Recycling trade has become an important initiative for major powers to address rare earth supply risks. With the help of recycling quality evaluation model, competitive intensity model, complex network method, and GIS analysis, the dynamics and characteristics of the global rare earth recycling trade network are revealed in this study. The results show that the global rare earth recycling market i
Background: The purpose of the study was to compare the real-world aflibercept treatment and visual outcomes, and to examine the adherence to pandemic guidelines in two groups of patients with treatment-naïve neovascular age-related macular degeneration (nAMD) before and during the first year of the COVID-19 pandemic in Sweden up to the 1-year follow-up. Methods: This is a retrospective observatio
PURPOSE: The aim was to study the association between dietary intake of B vitamins in childhood and the risk of islet autoimmunity (IA) and progression to type 1 diabetes (T1D) by the age of 10 years.METHODS: We followed 8500 T1D-susceptible children born in the U.S., Finland, Sweden, and Germany in 2004 -2010 from the Environmental Determinants of Diabetes in the Young (TEDDY) study, which is a p
PurposeThis article explores how firms' unresponsiveness to Black customer feedback influences Black (vs. White) customers' perceived firm-based discrimination and brand engagement.Design/methodology/approachTwo experimental studies (Study 1(N1) = 254) and Study 1(N2) = 484) are conducted to test the modeled relationships. The data are analyzed using ANOVA, PROCESS Model 4 and PROCESS Model 7.Find
Mg alloys are prone to pitting due to their non-uniform protective corrosionCorrosion layers, which can lead to an increase in stress intensity based on the notch effect, pit-to-crack transition, and thus premature failure. A small set of analytical methods to determine the extent of pitting and its effect on the resulting residual strengthResidual tensile strength is presented. Micrographs, 3D mi
Pyridoxal 5′-phosphate (PLP), the biologically active form of vitamin B6, is an essential cofactor in many biosynthetic pathways. The emergence of PLP-dependent enzymes as drug targets and biocatalysts, such as tryptophan synthase (TS), has underlined the demand to understand PLP-dependent catalysis and reaction specificity. The ability of neutron diffraction to resolve the positions of hydrogen a
Measurements of the differential production cross-sections of prompt and non-prompt J/ψ and ψ(2S) mesons with transverse momenta between 8 and 360 GeV and rapidity in the range |y|
Background: The Score Committee of the European Foot and Ankle Society (EFAS) developed, validated, and published the EFAS Score in 13 languages. Currently, the Danish version completed data acquisition and underwent further validation. Methods: The data were collected pre-operatively and post-operatively at a minimum follow-up of 3 months and mean follow-up of 6 months. Item reduction, scale expl
Purpose: The aim of this study was to investigate the contrast mechanisms of Contrast-enhanced steady-state free-precession (CE-SSFP) through the utilization of Bloch simulations in an experimental porcine model and in patients with acute myocardial infarction. Methods: Six pigs and ten patients with myocardial infarction underwent CMR and tissue characterization at 1.5 T whereas a Bloch simulatio
Photomultiplier tube (PMT) nonlinearities relevant for single shot high-speed lifetime phosphor thermometry were investigated by simulating decay curves with a light emitting diode (LED) at repetition rates between 1 Hz and 10 kHz. The PMT gain, LED decay time, and background radiant flux were also varied to investigate their impact on the measured decay time error. Errors in the measured decay tiPhotomultiplier tube (PMT) nonlinearities relevant for single shot high-speed lifetime phosphor thermometry were investigated by simulating decay curves with a light emitting diode (LED) at repetition rates between 1 Hz and 10 kHz.

From liquefied human seminal plasma, we purified the predominant basic protein which appears following liquefaction of coagulated semen. The protein was purified in the presence of di-isopropylfluorophosphate to retard its degradation. Heparin-Sepharose® chromatography was followed by gel filtration (Biogel® P 60) and by fast performance liquid chromatography on a reversed phase column (C8). The b
Managing the impacts of land use change on ecosystem services is essential to secure human wellbeing; but is a task often complicated by landscape-scale spatial dynamics. In this study, we focus on one type of spatial dynamic: multi-site interactions (MSI), which we define to occur when a change in the supply or use of an ecosystem service at one site affects that service at a second site. In sear
This study examines the impact of contextual factors on social mediated crisis by revisiting the concept of “modifier” in situational crisis communication theory (SCCT). Existing studies on “modifiers” in SCCT largely limit their scopes within the organizational domain and overlook the impact of contextual factors beyond organization, such as society, politics, and culture. To advance the understa
