An experimental investigation was performed to evaluate convective condensation and evaporation of R22, R32 and R410A inside a smooth tube (inner diameter 11.43 mm), a herringbone tube (fin root diameter 11.43 mm) and a newly developed enhanced surface EHT tube (inner diameter 11.5 mm) at low mass fluxes. The inner surface of the EHT tube is enhanced by dimple/protrusion and secondary petal arrays
Estimation of high-resolution terrestrial evapotranspiration (ET) from Landsat data is important in many climatic, hydrologic, and agricultural applications, as it can help bridging the gap between existing coarse-resolution ET products and point-based field measurements. However, there is large uncertainty among existing ET products from Landsat that limit their application. This study presents a
Vector navigation, i.e., maintaining a constant heading for a given amount of time, is hypothesized to provide a viable basis for the navigational feats of a number of long-distance animal migrants. Since animals following this strategy are subject to drift by wind or by ocean current, performing long migrations relying on vector navigation is particularly challenging. We tested whether vector nav
The natural products pulchrol and pulchral, isolated from the roots of the Mexican plant Bourreria pulchra, have previously been shown to possess an antiparasitic activity toward Trypanosoma cruzi, Leishmania braziliensis and L. amazonensis, protozoa responsible for the Chagas disease and leishmaniasis. These infections have been classified as neglected diseases, and still require the development
Neural stem cells (NSCs) derived from human fetal striatum and transplanted as neurospheres survive in stroke-damaged striatum, migrate from the implantation site, and differentiate into mature neurons. Here, we investigated how various steps of neurogenesis are affected by intrastriatal transplantation of human NSCs at different time points after stroke and with different numbers of cells in each
AIM: Injections administered by patients are one of the mainstays of diabetes management. Proper injection technique is vital to avoiding intramuscular injections, ensuring appropriate delivery to the subcutaneous tissues and avoiding common complications such as lipohypertrophy. Yet few formal guidelines have been published summarizing all that is known about best practice. We propose new injecti
Insects contribute considerably to global crop pollination, with pollination deficits being documented for multiple entomophilous or pollinator-dependent crops. Different cultivars of crops are being cultivated within and across production regions, so it is essential to understand the cultivar variability of pollination deficits. Here, we used a dataset from 286 sites from multiple production regi
Human dihydroorotate dehydrogenase (DHODH) catalyzes the fourth step of the de novo pyrimidine biosynthesis pathway and uses ubiquinone Q10, a lipophilic molecule located in the inner mitochondrial membrane (IMM), as its co-substrate. DHODH is anchored to the IMM by a single transmembrane helix located at its N-terminus. Nevertheless, how DHODH function is determined by its surrounding membrane en
C4b-binding protein (C4BP) is best known as a potent soluble inhibitor of the classical and lectin pathways of the complement system. This large 500kDa multimeric plasma glycoprotein is expressed mainly in the liver but also in lung and pancreas. It consists of several identical 75kDa α-chains and often also one 40kDa β-chain, both of which are mainly composed of complement control protein (CCP) d
Prostate-specific antigen (PSA) is a serine protease secreted by hath normal prostate glandular celts and prostate cancer cells. The major proteolytic substrates for PSA are the gel-forming proteins in semen, semenogelin (Sg) I and II. On the basis of the PSA cleavage map for Sg I and II, a series of small peptides (ie., ≤ 7 amino acids) was synthesized and coupled at the COOH terminus to 7-amino-
Reliable quantitative vegetation reconstructions for Europe during the Holocene are crucial to improving our understanding of landscape dynamics, making it possible to assess the past effects of environmental variables and land-use change on ecosystems and biodiversity, and mitigating their effects in the future. We present here the most spatially extensive and temporally continuous pollen-based r
The Paleocene-Eocene Thermal Maximum (PETM, ca. 56 Ma) is marked by a negative carbon isotope excursion (CIE) and increased global temperatures. The CIE is thought to result from the release of 13C-depleted carbon, although the source(s) of carbon and triggers for its release, its rate of release, and the mechanisms by which the Earth system recovered are all debated. Many of the proposed mechanis
Pedestrians and cyclists are so-called unprotected road users which are sensitive in the context of road safety. When it comes to road safety focus are often placed on pedestrians-cars and cyclist-cars, in this report focus are placed on the road safety between pedestrians and cyclists. Pedestrians and cyclists are often referred to a combined space, with or without a separation. The purpose of th
Accurate and continuous monitoring of inland surface water dynamics is vital for sustainable water resource management, climate impact assessment, and ecological planning. This study introduces a machine learning-based remote sensing-based data-fusion framework that improves Sentinel-3 radar altimeter (SRAL) estimations of water surface elevation (WSE) by integrating ERA5 reanalysis climate varia
Background: One of the preanalytical factors that can affect the results of arterial blood gas (ABG) analysis is the time from sample collection to analysis. A delay in analysis may affect the results due to factors such as ongoing cellular metabolism within the blood sample, gas exchange between the blood sample and the environment, and temperature changes. ABG analysis can be delayed for various

Traditionellt produceras trähus högst i två våningar p.g.a. historiskt svårkontrollerade brän-der. Idag är byggtekniken utvecklad och det är tillåtet att bygga trähus i flera våningar. Andel trähus som byggs med prefabricerade delar ökar idag i Sverige. Genom att producera montagefärdiga element i varierande storlek förflyttas husproduktionen från byggarbetsplats till fabrik. Syftet med studien äTraditionally, wooden houses are produced with a maximum of two floors, due to historical difficulties to control fires. Today, construction technology is developed so far that it is con-sidered safe to build wooden houses with additional floors. The percentage of wooden houses built with prefabricated parts is increasing in Sweden today. By producing module elements in various sizes, house produc
The etiology of childhood cancer is largely unknown. Approximately 1-10% of all childhood tumors are associated with known cancer predisposition syndromes. However, the contribution may be underestimated due to the failure to detect patients with genetic susceptibility for cancer when relying on known family pattern and anomalies. Growing evidence indicates that patients with genetic susceptibilit
