In the face of global climate change there is an increasing demand for biofuel, which exerts pressure on production and thus management of biofuel plantations. The intensification of whole-tree harvest from biofuel plantations increases export of nutrients. Returning ash from biofuel combustion to the forest plantations can amend the soil nutrient status and thus facilitate sustainable forest mana

Harvesting whole-tree biomass for biofuel combustion intensifies removal of nutrients from the ecosystem. This can be partly abated by applying ash from the combustion back to the system, as the ash is rich in nutrients. Ash is very alkaline and ash application raises soil pH, which in turn can stimulate microbial activity and thus decomposition and mineralization. Our aim was to test if ash induc

Ash from combustion of biofuels, for example wood chips, is often deposited as waste, but due to its high content of essential plant nutrients and alkalinity, it has been proposed to recycle ash as a fertilizer and liming agent in biofuel production forest. However, current legislation sets rather strict limitations for wood-ash application in biofuel production systems. The soil microfood web, th

Most plants form symbiotic associations with arbuscular mycorrhizal fungi (AMF). AMF increase the uptake of plant nutrients by extending their extra-radical mycelium (ERM) in the soil where other groups of microorganisms may suppress the activity of the ERM. However, little is known about such suppression in natural soils. This work aimed to investigate the incidence of AMF suppression among soils

Arbuscular mycorrhizal fungi (AMF) colonise roots of most plants; their extra-radical mycelium (ERM) extends into the soil and acquires nutrients for the plant. The ERM coexists with soil microbial communities and it is unresolved whether these communities stimulate or suppress the ERM activity. This work studied the prevalence of suppressed ERM activity and identified main components behind the s

Reutilizing biomass ashes in agriculture can substitute inputs of P from finite primary sources. However, recycling of ashes is disputed due to their content of toxic substances such as heavy metals. This study evaluates the potential risk of replacing easily soluble inorganic P fertilizer with P in biomass ashes in a barley crop grown on soil with adequate P status. Two contrasting doses of three

The present study investigates the potential benefits of the Mexican medicinal plant Lopezia racemosa (Onagraceae). Extracts and fractions from aerial parts of this plant were assessed to determine their antibacterial, antifungal, antiparasitic, anti-inflammatory and cytotoxic activities in vitro. Aerial parts of the plant were extracted with various solvents and fractionated accordingly. Extracts

Ethnopharmacological relevance: To study the potential benefit of the traditional Mexican medicinal plant Galium mexicanum Kunth (Rubiaceae). Hexane, chloroform, and methanol extracts as well as various fractions from these extracts were tested to determine antibacterial, antifungal, antiparasitic or anti-inflammatory activities in vitro. Materials and methods: Aerial parts of the plant were extra

Om måluppfyllelse ska kunna säkerställas för alla studenter behöver förutsättningar ges för lärandeprogression mot utbildningens mål. För att stärka dessa förutsättningar har progressionsplaner utvecklats för de naturvetenskapliga utbildningarna vid Lunds universitet. Progressionsplanen konkretiserar varje examensmål i etappmål med gradvis ökade krav och ger därigenom en överblick över den förvänt

Purpose: The purpose of this systematic literature review is to contribute to the knowledge about barriers to change in urban freight systems and to support managed changes toward more sustainable urban freight systems. Method: This paper is based on a systematic review covering 93 peer-reviewed journal articles. The study was designed to advance earlier research in this area by providing a system

Background: Musculoskeletal disorders are a costly burden for health care and social care services. Patients with musculoskeletal disorders are often treated by physiotherapists in primary health care. Psychosocial variables can be a significant obstacle to recovering from musculoskeletal injuries. The primary aim of this pilot study was to assess the feasibility of performing a prospective study

Parkinson’s disease (PD) and cardiovascular disease share many important risk factors, but some associations differ. However, there are no studies that have compared their shared and specific risk factors. The present study aimed to compare risk factors for PD, coronary events, or ischemic stroke. We prospectively analyzed data from 26,210 participants with lifestyle factors aged 45–73 years enrol

Background: People with severe mental illness who reside in supported housing (SH) and need a high level of assistance are at risk of an everyday life with little meaning and low community participation. Interventions to counteract that seem warranted, which was the rationale for this study. The aim was to investigate how residents and staff perceived an intervention designed to enhance meaningful

New-particle formation from vapors through molecular cluster formation is a central process affecting atmospheric aerosol and cloud condensation nuclei numbers, and a significant source of uncertainty in assessments of aerosol radiative forcing. While advances in experimental and computational methods provide improved assessments of particle formation rates from different species, the standard app

This paper focuses on how contributions are argued in research proposals in the humanities. Due to standardizing tendencies in research funding towards formats characteristic of science, technology, engineering and mathematics (STEM) subjects, there has been concern that the humanities are marginalized. In this study, ‘contribution statements’ were identified in proposals funded by the Bank of Swe

This research explores socio-technical perspectives of the demand-side management strategy of using the built environment for short term thermal energy storage. Here conceptualised as a niche innovation within the Danish socio-technical district heating landscapes, the research explores potentials and limitations of this building energy flexibility strategy from the perspective of district heating

This article explores the ethics of world heritage (WH) through a cosmopolitan lens. It proposes that cosmopolitanism provides fertile ground for the study of WH, in particular if combined with sensitivity to distinct indigenous ethical and political claims. Underpinning my article is the question of whether the politics of WH, despite its peaceful and universalist intensions, obscures local dispu

Purpose: The purpose of this paper is to investigate the role of smartphones among young people in everyday life, focusing on the activity of online search. This paper addresses the following research questions: What framings of the smartphone can be identified in the way that young people use, and describe, smartphones? What is the role of online search within these framings? By elucidating frami
