The purpose of this paper is to develop an approach to estimate peat accumulation rates (PAR) over recent decades based on the age and burial depths of roots from pine sapling and to use the newly developed approach to estimate spatial variations of PAR. To this end, we sampled 120 pine saplings growing in three plots at Rėkyva peatland in Lithuania and accounted for the microtopography around eac

The demand for agricultural products is expected to increase as a result of population growth, changed diets and demands for bioenergy. At the same time, agricultural yields in many regions are expected to be negatively impacted by climate change. Here we show, how altered winter conditions in combination with an extreme weather event impact reproductive development and yield of oilseed rape (Bras

The Constrained Application Protocol (CoAP) is a standard communication protocol for resource-constrained devices in the Internet of Things (IoT). Many IoT deployments require proxies to support asynchronous communication between edge devices and the back-end. This allows (non-trusted) proxies to access sensitive parts of CoAP messages. Object Security for Constrained RESTful Environments (OSCORE)

There has been a lack of more profound studies and information on the growth of modern youth culture in Sweden. It has often been alleged that this culture was developed in the 1950s by the more conspicuos youth groupings. I question this statement, and so I have chosen to investigate the 1940s, a much too neglected period. A central thought is that the youth cultures of the 1930s and 1940s were a

Forestry and nature conservation can benefit from rapid on-line information on forest disturbances, such as insect attacks. This type of information would facilitate timely field studies and enable more rapid counter measures, as well as enable studies of the dynamics of an insect outbreak. In this study we developed a method based on MODIS derived NDVI for near real-time monitoring of insect indu

Climate change affects the functioning of all of the components of food systems, often in ways that exacerbate existing predicaments and inequalities among regions of the world and groups in society. At the same time, food systems are a major cause of climate change, accounting for a third of all greenhouse gas (GHG) emissions. Therefore, food systems can and should play a much bigger role in clim

In most genres of fiction representations of a profession, discipline or calling must broadly resonate with the conceptions of that role held by audiences. But very few represenations of PR practice to be found in novels written by UK-based writers draw a picture of PR activity that sits comfortably with the ”idealised” models offered by organisations such as the Chartered Institute of Public Re

To assess the extent to which trees in a semi-arid silvopastoral system (SPS) can offset the greenhouse-gas (GHG) emissions of the system's livestock, this study used two process-based models (STEP-GENDEC-N2O and DynACof) to simulate 9 years of agricultural activity and resulting emissions in a SPS that has been operating in sahelian Senegal. STEP-GENDEC-N2O simulated soil N2O and CO2 fluxes, plus

In current times of global change, several sources of stress such as contaminants and high temperatures may act synergistically. The extent to which organisms persist in stressful conditions will depend on the fitness consequences of multiple simultaneously acting stressors and the genetic basis of compensatory genetic responses. Ivermectin is an antiparasitic drug used in livestock that is excret

Research into repair within the circular economy (CE) typically focuses on technical aspects of design, policy, and markets, and often assumes or implies simplified conditions for the user/owner and the product-system to explain the barriers to scaling repair activities. By integrating life cycle and temporal dimensions (time-sequence) into a broad System of Repairability framework, we demonstrate

Yield loss caused by insect pests remains a substantial problem in agriculture. Chemical control, with potential negative effects on non-target organisms, is still the main tool for pest management. For pest species with limited dispersal capacity, rotation of the crop in time and space has potential as an alternative management measure. This is particularly important in organic farming, where mos

There is an increasing interest in landscape-scale perspectives of ecosystem functioning to inform policy and conservation decisions. However, we need a better understanding of the stability of ecosystem functioning (e.g. plant productivity) at the landscape scale to inform policy around topics such as global food security. We investigate the role of the ecological and environmental context on lan

Industry 4.0, with its focus on flexibility and customizability, is pushing in the direction of wireless communication in future smart factories, in particular, massive multiple-input-multiple-output (MIMO) and its future evolution of large intelligent surfaces (LIS), which provide more reliable channel quality than previous technologies. At the same time, network slicing in 5G and beyond systems

Family accommodation (FA) is widely-recognised as an important clinical phenomenon in obsessive–compulsive disorder (OCD) and anxiety disorders, and is related to poorer treatment outcomes. However, FA has not been quantitatively explored in Body Dysmorphic Disorder (BDD). The aim of this study was to investigate the patterns and correlates of maternal accommodation in adolescent BDD, and its asso

Almost 20 years ago, MSB's representatives published general advice and comments on fire protection at camping facilities (SRVFS2004:12). However, this is considered general advice and is not technically mandatory. This advice is linked to 2 kap. 2 § of the Act (2003:778) on protection against accidents, which in this case points out an obligation for owners and users of camping facilities to main

In response to the growing demand for sustainable practices in the hospitality industry, many hotels have concentrated on operational measures to reduce energy consumption. However, the potential for promoting voluntary customer-initiated energy-saving behaviors has been largely overlooked. This study fills that gap by investigating how environmental values (egoistic, altruistic, and biospheric) a

In the first national human biomonitoring study in the Slovenian population of adults (18–49 years), including men (n = 297) and lactating primiparous women (n = 304), exposure to polycyclic aromatic hydrocarbons (PAHs) was evaluated. Nine urinary metabolites of four parent PAHs were determined. These included 1-hydroxypyrene (1-OHPYR), 2-hydroxynaphthalene (2-OHNAP), 2-hydroxyphenanthrene (2-OHPH
