Sustainable greenhouse systems - The potential of microorganisms

Due to the high input of means of production and productivity, environmental issues have been highlighted in horticulture for some years. They concern the impact of horticultural production systems on the environment in a narrow (i.e., occupational, crop) and broader (CO2 emission, nutrient leakage, chemical pollution) sense. In all production systems, multiple plant-microbial interactions occur.

Implementing a new texture-based soil evaporation reduction coefficient in the FAO dual crop coefficient method

Crop evapotranspiration (ET) is a fundamental component of the hydrological cycle, especially in arid/semi-arid regions. The FAO-56 offers an operational method for deriving ET from the reduction (dual crop coefficient Kc) of the atmospheric evaporative demand (ET0). The dual coefficient approach (FAO-2Kc) is intended to improve the daily estimation of ET by separating the contribution of bare soi

Soil carbon and microbes in the warming tropics

Climate warming could destabilise the Earth's largest terrestrial store of reactive carbon (C), by accelerating the decomposition of soil organic matter. A third of that C store resides in the tropics. The potential for tropical soils to sequester C, or to act as an additional source of CO2, will depend on the balance of C inputs and outputs, mediated by the response of soil microbial communities

Interactions in the 2×2×2 factorial randomised clinical STEPCARE trial and the potential effects on conclusions : a protocol for a simulation study

Background: Randomised clinical trials with a factorial design may assess the effects of multiple interventions in the same population. Factorial trials are carried out under the assumption that the trial interventions have no interactions on outcomes. Here, we present a protocol for a simulation study investigating the consequences of different levels of interactions between the trial interventio

Soil depth and tillage can characterize the soil microbial responses to drying-rewetting

The influence of climate on soil microorganisms governs the input and output fluxes of carbon (C) from soils. The study of the drastic responses to drying-rewetting offers an opportunity to assess an aspect of ‘soil health’ via evaluating the role of microbes in soil biochemistry and C cycling. Recent evidence has consistently shown that communities exposed to extreme moisture fluctuations recurre

Effects of Elevated Atmospheric CO2 Concentration on Insect Herbivory and Nutrient Fluxes in a Mature Temperate Forest

Insect herbivory is one of the most important ecological processes affecting plant–soil feedbacks and overall forest ecosystem health. In this study, we assess how elevated carbon dioxide (eCO2) impacts (i) leaf level insect herbivory and (ii) the stand-level herbivore-mediated transfer of carbon (C) and nitrogen (N) from the canopy to the ground in a natural mature oak temperate forest community

Smartphoned Tourists in the Phygital Tourist Experience

The present thesis explores how the tourist experience is re-articulated through the mediation of smartphones. I adopt the postphenomenological theory of mediation as the overarching ontological position, placing the role of technologies on an ontological level, as mediators of perception and experience. The new tourist that emerges from smartphone mediation is the smartphoned tourist, that is a t

Municipal wastewater treatment by microsieving, microfiltration and forward osmosis : Concepts and potentials

Conventional wastewater treatment plants are designed for treating manmade wastewater (e.g., from households and industries) and to protect the environment (e.g., receiving water bodies) and humans from adverse effects.The objective of this work was to investigate the feasibility of treating municipal wastewater without a biological treatment step by applying different separation processes, such a

Do the energy fluxes and surface conductance of boreal coniferous forests in Europe scale with leaf area?

Earth observing systems are now routinely used to infer leaf area index (LAI) given its significance in spatial aggregation of land surface fluxes. Whether LAI is an appropriate scaling parameter for daytime growing season energy budget, surface conductance (Gs), water- and light-use efficiency and surface–atmosphere coupling of European boreal coniferous forests was explored using eddy-covariance

Cancer incidence in cohorts of workers in the rubber manufacturing industry first employed since 1975 in the UK and Sweden

Objectives Increased cancer risks have been reported among workers in the rubber manufacturing industry employed before the 1960s, but it is unclear for workers hired subsequently. The present study focused on cancer incidence among rubber workers first employed after 1975 in Sweden and the UK. Methods Two cohorts of rubber workers employed for at least 1 year were analysed. Standardised incidence

Environmental Assessment of Emerging Bio-based Production - Possibilities in a Future Bio-economy

The bio-economy has been put forward as a strategy to increase economic growth without this leading to increased emissions of greenhouse gases. A key concept behind the bio-economy is the increased use of biomass for applications such as the production of bio-based chemicals and materials but also an increased importance for biotechnology and biorefinery systems in the production of these products

Targeted alpha therapy in a systemic mouse model of prostate cancer - a feasibility study

225Ac-PSMA-617 targeted-therapy has demonstrated efficacy in 75-85% of patients; however, responses are not durable. We aimed to establish translatable mouse models of disseminated prostate cancer (PCa) to evaluate effectiveness of 225Ac-PSMA-617 at various disease stages. Methods: C4-2, C4-2B, or 22Rv1 cells were injected into the left ventricle of male NSG mice. Disease progression was monitored

Exosomal miR-142-3p is increased during cardiac allograft rejection and augments vascular permeability through down-regulation of endothelial RAB11FIP2 expression

AIMS: Exosome-mediated microRNA transfer is a recently discovered mode of cell-to-cell communication, in which microRNAs act as paracrine molecules, exerting their regulatory effects in recipient cells. T cells and endothelial cells are two main players in the mechanism of acute cellular cardiac rejection. The aim of this study was to investigate the role of exosomal microRNAs in the crosstalk bet

Genome-wide association study on 13 167 individuals identifies regulators of blood CD34+cell levels

Stem cell transplantation is a cornerstone in the treatment of blood malignancies. The most common method to harvest stem cells for transplantation is by leukapheresis, requiring mobilization of CD34+ hematopoietic stem and progenitor cells (HSPCs) from the bone marrow into the blood. Identifying the genetic factors that control blood CD34+ cell levels could reveal new drug targets for HSPC mobili

Enhancing archaeological mobility studies : Bayesian-modelled isoscapes and high-resolution refinement of the bioavailable strontium baseline in southern Scandinavia

Mapping spatial variability of bioavailable strontium isotopes (87Sr/86Sr) is fundamental to robust analyses of prehistoric human and animal mobility and provenance based on strontium isotope data. A key challenge is how to construct and extrapolate a baseline for specific landscapes to enable meaningful correlation with high-resolution archaeological data. This study presents a regional high-reso

Prospective, Multicentre Feasibility Study of Remote Colon Capsule Endoscopy Using the OMOM CC100 System

Background and Aims: Colon capsule endoscopy (CCE) provides a non-invasive alternative to traditional colonoscopy. This study evaluated the feasibility, safety, diagnostic yield (DY), and patient satisfaction of the OMOM CC100 CCE system, with special focus on fully remote (n = 30) and partially remote (n = 89) administration across four centres to advance decentralised models. Methods: This prosp

International Expert Consensus on the Management of Acute Aortic Type B Intramural Haematoma and Penetrating Ulcer

Objective: The aim of this study was to achieve an international expert consensus on managing acute type B penetrating aortic ulcers (PAUs) and intramural haematomas (IMHs). Methods: A modified Delphi consensus process was employed to develop recommendations for the management of acute type B PAU and IMH. Surveys were sent to international experts practicing in high volume aortic centres worldwide
