Observationer och modelleringsstudier har visat att den globala markytan har genomgått betydande förändringar under de senaste decennierna, drivet av både naturliga och antropogena faktorer, såsom förändringar i ekosystemens produktivitet, bränder och markanvändning. Markytans förändringar kan potentiellt påverka det lokala och regionala klimatet genom förändringar i processer som sker mellan jordObservation and modelling studies have indicated that the global land surfaces have been undergoing significant changes in the past few decades, driven by both natural and anthropogenic factors, such as changes in ecosystem productivity, fire and land use. Land surface changes can potentially influence local and regional climate through land-atmosphere interactions. Continued greenhouse gas emissi

Estimating Cartesian contact forces and torques enables external force supervision for robotic manipulators and even force-controlled applications while avoiding the need for additional external sensing. Redundant manipulators facilitate the problem of Cartesian contact force and torque estimation (CCFE) at the TCP, since an increased amount of joint level information is available for estimating t

The paper considers multi-hop wireless mesh networks that serve multicast periodic packet traffic. The packets from each packet stream are generated at the stream's source node and traverse a number of wireless nodes in order to reach their multiple destination nodes. Packet periodicity means that a common repeatable frame of time slots is defined and that the packets to be transmitted arrive at t

Background: Antisocial personality and psychopathic traits have constantly been found to accompany criminal and aggressive behaviors, but little attention has been given to aspects of character maturity and its relation to such behaviors. The present study investigated (1) whether level of character maturity (low, medium, and high) is associated with amount of aggressive antisocial behaviors (AABs

A chaos expanded Fourier split-step method is derived and applied to a narrow-angle parabolic equation. The parabolic equation has earlier been used to study deterministic settings. In this paper we develop a spectral-based Fourier split-step method that will take a limited degree of information about the environment into account. Our main focus is on proposing an efficient method for computationa

The purpose of this study is to present and analyze previously unpublished quantitative agricultural data for the area on the shores of Lake Chad in Chad, and explore its relations to hydro-climatic factors (lake levels, rainfall and temperature). This is a rural area with livelihoods based on agropastoral and fishing activities, which are directly dependent on the region's high-varying hydro-clim

Geochronologies of intramontane depression (basin) fluvial sedimentation enable to identify through time periods of alluviation and river erosion, and date fault movement. For these purposes the optically stimulated luminescence (OSL) dating has been applied to evaluate and to develop a geochronological framework of river terraces. We study the age of river terrace deposits of the Czarny Dunajec R

Measurements of the land-atmosphere exchange of the greenhouse gases methane (CH4) and carbon dioxide (CO2) in high Arctic tundra ecosystems are particularly difficult in the cold season, resulting in large uncertainty on flux magnitudes and their controlling factors during this long, frozen period. We conducted snowpack measurements of these gases at permafrost-underlain wetland sites in Zackenbe

To celebrate the research visions and accomplishments of the late Roscoe O. Brady (1923-2016), remembrance commentaries were requested from several of his postdoctoral research fellows and colleagues. These commentaries not only reflect on the accomplishments of Dr. Brady, but they also share some of the backstories and experiences working in the Brady laboratory. They provide insights and perspec

Research has shown that people with psychiatric disabilities who attend a day center rate their satisfaction with daily occupations equally in comparison with non-attendees. The current study investigates which occupations the target group performs and also differences in occupational choices between attendees and non-attendees. Reported occupations were analyzed with content analysis. Day center

This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization potential, as well as, environmental safety. Data from the suitable read across analog isobornyl acetate (CAS # 125-12-2) show that this material is not genotoxic, provided a MOE> 100 for the repeated d

There has been an increased interest in ways of measuring the value of new therapeutic options in oncology. An example of this in a European context is the ESMO Magnitude of Clinical Benefit Scale (ESMO-MCBS). The purpose of this study is to analyse how the value scales, exemplified with ESMO-MCBS, developed mainly to assist decisions by physicians, relate to other measures of clinical benefit and

Systems approaches for the study of immune signaling pathways have been traditionally based on purified cells or cultured lines. However, in vivo responses involve the coordinated action of multiple cell types, which interact to establish an inflammatory microenvironment. We employed standardized whole-blood stimulation systems to test the hypothesis that responses to Toll-like receptor ligands or

Projections by the Intergovernmental Panel on Climate Change (IPCC) and sea ice forecasts suggest that Arctic sea ice will decline markedly in coming decades. Expected effects on the entire ecosystem include a contraction of suitable polar bear habitat into one or few refugia. Such large-scale habitat decline and fragmentation could lead to reduced genetic diversity. Here we compare genetic variab

This paper presents a simulation model of the temperature's influence on the electromagnetic characteristics of an Interior Permanent Magnet Synchronous Machine (IPMSM). Simulation results of an IPMSM traction machine is presented, and experimental measurements verify the accuracy of the model; no load measurements provide the induced voltage as function of temperature and dynamic tests evaluate t

Organizational image is a contested concept in interdisciplinary research, drawing upon organizational communication, corporate communication, organization, marketing, and public relations studies. As such, organizational image is seen as the impression of an organization that exists among both external stakeholders as well as organizational members themselves as “construed external images” and “d

In many system identification methods, process model parameters are considered stochastic variables. Several methods do not only yield expectations of these, but in addition their variance, and sometimes higher moments. This paper proposes a method for robust synthesis of the proportional-integral-derivative (PID) controller, taking parametric process model uncertainty explicitly into account. The
