Agroecology is gaining ground within the debate on how to address systemic social and environmental problems in agriculture. However, it remains marginalized in agricultural research and development plans around the world. This paper analyzes agroecology as a socio-technical niche in Uganda, where its emergence in part can be seen as an unintended consequence of neoliberalist development. The case

PURPOSE: Even though retinal vascular changes following ischaemia have been poorly understood, the upregulation of vasoconstrictive endothelin-1 (ET-1) receptors (ETA/ETB) following global cerebral ischaemia has been described. The aim of this study was to investigate whether or not the MEK/ERK1/2 pathway is involved in the observed upregulation and whether specific MEK/ERK1/2 inhibitors U0126 and

The issue of governance has become a fashionable topic of research in the study of post-Soviet societies. The key argument of this article is that there are multiple paradigms and understandings of ‘good governance’, some of which concur with the global (Western) understanding, while others offer alternative criteria. In this article, we explore the specifics of governance system in Uzbekistan and

To mitigate dangerous climate change, a transition to a new and sustainable energy system is needed. In this system, solar energy will need to be a key player. Prices of electricity made from solar cells have declined rapidly over the recent decades, making solar energy competitive in more markets. However, further price reductions and new innovations are needed for solar cell technology to fulfil

Objectives: To identify diagnostic and prognostic biomarkers in the cerebral white (WM) and the deep grey matter (GM) in patients with Parkinson’s disease (PD) and atypical parkinsonian syndromes (APS) using magnetic resonance imaging (MRI). Methods: Patients with a clinical diagnosis of PD, multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) were included in the study. Patients

The effect of the addition of n-hexanol as co-surfactant on the structure of cetyltrimethylammonium bromide (CTAB) micelles has been studied using small-angle X-ray and neutron scattering (SAXS, SANS). Contrast variation neutron scattering experiments were performed to determine the structure of both pure CTAB and n-hexanol modified CTAB micelles. The incorporation of n-hexanol leads to an elongat

In the many published theories on the retention in reversed-phase chromatography (RPC), the focus is generally on the effect of the concentration of the mobile phase modulator(s), although temperature is known to have a significant influence both on the retention and on the selectivity between the adsorbates. The aim of this study was to investigate and model the combined effects of the temperatur

Respiratory allergic disease represents a global health problem, 30% of the population suffers from allergic rhinoconjunctivitis and 20% suffer from asthma. Allergy immunotherapy induce immunological tolerance and thereby modify the response to allergens and sublingual immunotherapy (SLIT) offers the possibility of home administration of allergen therapy, but adherence is more uncertain. The aim o

Metallic implants are commonly used as surgical treatments for many orthopedic conditions. The long-term stability of implants relies on an adequate integration with the surrounding bone. Unsuccessful integration could lead to implant loosening. By combining mechanical loading with high-resolution 3D imaging methods, followed by image analysis such as Digital Volume Correlation (DVC), we aim at ev

Anion exchange membrane fuel cells (AEMFCs) are considered as one of the most important next-generation energy conversion technologies. AEMFCs convert chemical energy into useful electrical energy and have great potential forachieving high conversion efficiencies. In addition, the faster oxygen reduction kinetics under alkaline conditions are advantageous for the use of non-noble metal catalysts (

BACKGROUND: High physical exertion during work is a risk factor for back pain and long-term sickness absence.OBJECTIVE: To investigate which factors are associated with physical exertion during manual lifting.METHODS: From 14 workplaces across Denmark, 200 blue-collar workers reported perceived physical exertion (Borg-CR10) during manual lifting from floor to table height of 5, 10, 20 and 30 kg at

The study primarily draws on genetic structuralism in unraveling social transformations embedded in short stories written by Egyptian authoresses. It also makes use of feminist concepts given that the content in question is written by Egyptian women writers and hence blends general social transformations with those affected by feminism. Four Egyptian authoresses were selected for this study along

In order to obtain a higher thermal efficiency, the inlet temperature of gas turbines is gradually increased. However, this increases the thermal load on the first stage vane endwall surface. Therefore, an advanced cooling technique must be implemented for the endwall cooling to ensure that the gas turbine operates safely. In the current study, effects of swirling coolant flow from the upstream sl

Recently, the biased and highly selective 5-HT1A agonists, NLX-112, F13714 and F15599, have been shown to alleviate dyskinesia in rodent and primate models of Parkinson's disease, while marginally interfering with antiparkinsonian effects of levodopa. To provide more detailed information on the processes underlying the alleviation of dyskinesia, we have here investigated changes in the spectral co

Background and aims: There is convincing evidence that adaptive immune responses affect the development of atherosclerosis and thrombosis and several autoimmune diseases are associated with increased cardiovascular risk. However, our understanding of the underlying mechanisms remains limited. We investigated how biomarkers reflecting four aspects of autoimmunity: apoptosis, inflammation, tissue de
