This investigation consisted of developing and evaluating solar dryers together with semi-permeable membrane pouches for drying juicy fruits in low-income tropical countries. Two design iterations were carried out including prototype modelling and testing. The latest developed solar dryers were a passive and an active solar dryer. Modelling was initially carried out mathematically using an equatio

Vanadia was deposited on TiO2, ZrO2, HfO2, Nb2O5, and Ta2O5 supports using impregnation with either an oxalic acid solution of NH4VO3 or a solution of vanadyl acetylacetonate in ethanol. Prepared samples, with a nominal vanadia content in the range 0.5–2 monolayers, were characterized with X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman and infrared spectroscopy, and were us

When skin specimens are exposed in vitro to L-dopa and catecholamines these substances accumulate in the Langerhans cells where they can be visualized with the histofluorescence method of Falck and Hillarp. Some methodological aspects are discussed and a preliminary study of Langerhans cells in contact allergy is reported.

The challenges for creating a greener economy and the institutional framework for sustainable development pass necessarily, or mostly, through cities, as they concentrate a large and growing part of the world’s economy and population, as well as decision-making power. With the processes of urbanization and rural-urban transformation, the economy in cities, especially in cities of developing countr

Three titania polymorphs, anatase, rutile, and TiO2(B), were used as supports for vanadia. Catalysts with nominal loadings corresponding to 1.5 and 5 theoretical layers were prepared. True monolayer samples were obtained by NH3(aq)-treatment of the samples with 5 nominal vanadia layers. Prepared catalysts were characterized by chemical analysis, ESR, and high-resolution electron microscopy. It was

This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying

Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. Utilizing data collected from a pressure sensor inside the pipette could be a way of automatically verifying different aspects related to the p

Objectives To study the effect of a progressively enhanced rest–shade–hydration–hygiene (RSHH) intervention on kidney injury and inflammation biomarkers, and rates of clinical acute kidney injury (AKI) in Nicaraguan sugarcane workers with a very high rate of chronic kidney disease of non-traditional origin (CKDnt). Methods We analysed serum creatinine and C-reactive protein (CRP) and leukocyturia

Epilepsy affects approximately 50 million people worldwide, and over 30% of patients are considered treatment resistant to currently available anti-seizure drugs. Neuropeptide Y (NPY) has been shown to inhibit excitatory synaptic transmission in hippocampal slices from human epilepsy patients via Y2 receptors (Y2Rs), and overexpression of NPY and/or Y2R in the hippocampus reduces seizures in roden

AimsDyspnoea accounts for nearly 5% of emergency department (ED) visits. Our aim was to describe the in-hospital and long-term outcomes of patients admitted to the ED for dyspnoea, based on their underlying aetiology, and to determine if prognosis varies according to the hospitalization setting.MethodsWe analyzed 18 903 consecutive patients (48% male, average age 73 years) hospitalized after an ED

Climate change can raise average temperatures and humidity and induce more frequent and stronger extreme weather events. This intensifies the need for studies on indoor climate and energy use in livestock buildings as it will affect animal welfare and farmers’ economy in terms of production, energy demand and needed investments. The aim of this review was to identify knowledge gaps and the need fo

This chapter critically examines a number of ethical dilemmas at stake for professionals working with refugee children and families in Denmark within the field of early childhood education. While national guidelines promote diversity by framing cultural differences as valuable resources, integration policies often result in efforts aimed at assimilation. The chapter explores how everyday ethical j

Accurate, high-resolution global land use and land cover (LULC) mapping is crucial for environmental monitoring, but remains challenging when relying solely on multispectral data. Most existing global LULC mapping studies rely exclusively on multispectral observations, and even those that incorporate synthetic aperture radar (SAR) data often fail to fully exploit the information it provides. SAR p

Cryo-scanning electron microscopy (CryoSEM) permits the preparation and detailed imaging of bulky samples while keeping them in a hydrated state. For plant biology, cryofractures give information on cell ultrastructure and tissue organisation within a much larger context that is the whole organ or organism. To date, a method to locate fluorescence reporters on the cryofracture has not been reporte

Background Early-onset depression contributes significantly to long-term disability and suicide, making high-quality healthcare for young people with depression a critical concern. Medical record review (MRR) is widely used to assess healthcare quality. However, its application to depression care for children and adolescents appears underexplored, with no consensus on conceptualising or measuring
