Wetland area has decreased dramatically compared with preindustrial times, and in manyagricultural areas almost all wetlands have been drained to gain cropland. The trend hasin recent years been reversed because society has realized the many benefits of wetlandfunctions, such as for nutrient retention and flood control. In this study we inventoried 75 wetlands in Uppland and Halland for insects an

Today, huge amounts of data are produced, collected, and presented in all kinds of contexts. The ability to critically examine and evaluate information and arguments in relation to empirical evidence is often referred to as information literacy. It is of utmost importance that students are adequately scaffolded to develop this ability, to be able to become democratic citizens. The study presented

Diversifying cropping systems by increasing the number of cash and cover crops in crop rotation plays an important role in improving resource use efficiency and in promoting synergy between ecosystem processes. The objective of this study was to understand how the combination of crop diversification practices influences the performance of arable crop sequences in terms of crop grain yield, crop an

What information is encoded in the cries of human babies? While it is widely recognized that cries can encode distress levels, whether cries reliably encode the cause of crying remains disputed. Here, we collected 39201 cries from 24 babies recorded in their homes longitudinally, from 15 days to 3.5 months of age, a database we share publicly for reuse. Based on the parental action that stopped th

This paper provides an overview of the Neurigona species found in Iran. During our studies in northern Iran four species of the genus Neurigona Róndani, 1856 have been collected, three of which for the first time in Iran: Neurigona helva Negrobov & Tsurikov, 1990, Neurigona pallida (Fallén, 1823) and Neurigona pseudolongipes Negrobov, 1987. One species, Neurigona persiana Pollet & Kazerani

Three different circulation mechanisms are analyzed: 1) through-flow of a river; 2) wind generated oscillations; and 3) convective currents induced by heat flow from the bottom sediments. The through-flow takes place between the ice and a depth, which is mainly determined by the conditions at the inlet of the river into the lake. Just below this depth there is a sharp thermocline. The water mass b

A conversational program, MAGROR, for storm water run-off is described. Such programs are necessary for practical engineering purposes related to storm water run-off. The program will assess storm water run-off and recommend optimal pipe dimensions. The program has an automatic capability. The principle of a connecting system for run-off piping is shown schematically. Theoretical considerations ar

Ice observations were made in the Rane River 1974-1978. Observations of formation of ice, growth of ice, critical velocities, hydrodynamic stability, supercooled water, ice production in rapids and breakup were theoretically analyzed. Depending on the water velocity an ice cover formed after 40-100 negative °C-degree-days. The growth of ice took place at a static growth when the water velocity was

While prior research has gleaned important insight into consumers’ social media engagement, an important literature-based tension exists that warrants further attention. On the one hand, females are increasingly empowered (e.g., through their rising spending power). On the other hand, advertising-based gender stereotypes persist, thus limiting female consumers’ empowerment and decelerating adverti

This thesis is composed of four papers, the first two show the attempts made to extend the Pythia event generator to simulate heavy-ion collision events. The other two papers show methods to improve the hadronization mechanism in the Pythia model for a bettter agreement with the experimental data of pp and heavy-ion collisions.Paper I introduces a new model named Angantyr for heavy-ion collision e

Real-time measurement of soil water content (θ) and pore electrical conductivity (ECp) is essential to improve water irriga-tion efficiency and agricultural productivity. Low-cost frequency domain reflectometry (FDR) sensors are now representinga powerful tool for irrigation management purposes. However, compared to the time domain reflectometry (TDR), FDRsensors’ accuracy to predict θ and ECp is

The European Open Science Cloud is a pan-European initiative that aims at developing a federated infrastructure that supports scientific research and Open Science. Having the FAIR principles at the core of Open Science practices, the Environmental Research Infrastructures (ENVRIs) that operate in Europe collaborate at cluster level (the ENVRI cluster) continuously improving the FAIRness of their s

This special edition magazine is a collection of short essays aiming to empower students and teachers who advocate for heterodox economics teaching. The magazine presents innovative ways to introduce heterodox content in the classroom and shares exercises that incorporate real-world issues. It is also a collective thinking exercise on how to strategize for needed curriculum changes, notably throug

Introduction/Background Completetumor resection is the most relevant prognostic factor for overall survival in high grade serous ovarian cancer (HGSOC) patients. The current standard for classification of postoperative residual disease is surgeon´s subjective evaluation at the end of surgery. Thus, a reliable objective predictive marker is currently missing.MethodologyIn this prospective single-ce
