As a solution to solving energy consumption and environment problems, photovoltaics has become one type of the promising devices to convert solar energy into electricity directly. In some special areas like in space, a kind of photovoltaics with lightweight and reliable properties is needed to supply power. Therefore, photovoltaics based on the group III-V semiconductor nanowires has been emerged
Lipase from Penicillium roquefortii immobilized on porous polypropylene particles was used for enzymatic preparation of 1,2-diglycerides by alcoholysis in organic media. A screening of commercially available lipases showed that lipases from Penicillium species produced high amounts of 1,2-diglycerides from triglycelirles. Reaction parameters such as solvent, alcohol, water activity, and fatty acid
Importance: Preterm birth has previously been associated with increased risks of hypertension and diabetes, but not ischemic heart disease (IHD), in adulthood. The reasons for this lack of association with IHD despite associations with its risk factors have been elusive, but may be associated with methodologic issues, such as survivor bias, in prior studies. Objective: To determine whether preterm
Reduced chemical kinetic mechanisms are essential for atmospheric chemistry modeling where the use of explicit kinetic schemes is too computationally demanding. By tailoring mechanisms to specific cases, the size of the mechanism can be kept small, without significant loss of accuracy in predictions of selected species’ concentrations. In the present work, we present small kinetic mechanisms tailo
Sera from 40 Swedish children diagnosed as having Type 1 (insulin-dependent) diabetes mellitus during a one year period along with 40 age and geographically matched control subjects were tested for antibodies to a Mr-64000 islet protein by immunoprecipitation of 35S-methionine-labelled rat islet amphiphilic proteins. Of the 40 diabetic patients, 29 (73%) were found to be positive whereas all 40 co
Early Vascular Aging (EVA): New Directions in Cardiovascular Protection brings together the last decade of research related to the characterization of EVA, as well as the predictive power of pulse wave velocity (PWV). The book presents a novel approach to the problem of cardiovascular disease, showing it in relation to great vessels disease and revealing a comprehensive approach to the problem of
Background: The Evaluation in Ayres Sensory Integration ® (EASI) is a performance-based assessment tool, aiming to assess sensory perception, sensory reactivity, postural/ocular/bilateral integration, and praxis in children aged 3–12 years. These types of tests are currently not available in Swedish. A structured, multistep process of translation is crucial for maintaining equivalence between the
We analyze the size evolution of pebbles accreted into the gaseous envelope of a protoplanet growing in a protoplanetary disk, taking into account collisions driven by the relative sedimentation speed as well as the convective gas motion. Using a simple estimate of the convective gas speed based on the pebble accretion luminosity, we find that the speed of the convective gas is higher than the sed
The potential for replacing the fossil-based Polyoxymethylene (POM) and Polyamide 66 (PA 66) in polymer gear applications with a bio-based Polyamide 6.10 (PA 6.10) was studied and is presented in the article. The use of bio-based plastics is increasing but mostly in undemanding applications like packaging. High-performance plastics are needed in polymer gear transmissions since their operational c
We exhibit families of 4-CNF formulas over n variables that have sums-of-squares (SOS) proofs of unsatisfiability of degree (a.k.a. rank) d but require SOS proofs of size nΩ ( d ) for values of d = d(n) from constant all the way up to nδ for some universal constant δ. This shows that the nO ( d ) running time obtained by using the Lasserre semidefini
This study is an attempt to improve the loading and release potential of silver oxide nanoparticles (AgO NPs) using Oleic acid based bio-surfactant isolated from Enteromorpha instestinalis. The isolated Oleic acid based bio-surfactant was characterized using GC–MS, NMR, and HPLC. The AgO NPs were then surface-functionalized with the bio-surfactant and analyzed using XRD, HR-TEM/SAED, DLS, UV–Vis,
A 27-47-GHz differential cascode power amplifier for millimeter-wave 5G new radio applications is presented. The PA is a three-stage design using inductively coupled impedance transformers with 31-dB nominal power gain. A device periphery ratio of 1:2:6 is adopted for predriver, driver, and final stage, respectively. A gain equalization technique was used in the interstage transformers to obtain t
Background: As several reports have raised a variety of environmental, health, and safety issues related to ultraviolet (UV) filters, it is crucial to understand the trends in the exposure of the population to UV filters. Objective: To determine the frequency of UV filter usage in sunscreens and other cosmetic products in Thai market. Methods: We surveyed the UV filter labelling on sunscreens and
This study investigated the tolerance and safety of pasteurized donor human milk (PDHM) given either alone or together with commercially-used supplements in a porcine model of premature infants. A porcine model, mimicking human neonates at 30-32 weeks of gestational age, was used. The 7-day experiment was performed on 20 piglets. After birth, the piglets were infused with porcine immunoglobulins v
In order to avoid environmental pollution and eliminate the need for using fertiliser, this study assessed for the first time the optimum performance of mature (in operation since 2011) vertical flow constructed wetlands in treating domestic wastewater (with and without hydrocarbon) and the subsequent recycling of the outflow to irrigate chillies (De Cayenne; Capsicum annuum (Linnaeus) Longum Grou
Background Tonsillectomy is a common surgical procedure. Recent evidence suggests that tonsils play an important role in our immune system. We thus hypothesize that individuals with tonsillectomy may face an increased incidence of autoimmune diseases in their later life. Methods All individuals that had a tonsillectomy in Sweden between 1997 and 2012 were identified from the Swedish Hospital Disch
Objectives To study the impact of time in therapeutic range (TTR) and international normalised ratio (INR) variability on the risk of thromboembolic events, major bleeding complications and death after mechanical heart valve (MHV) implantation. Additionally, the importance of different target INR levels was elucidated. Methods A retrospective, non-randomised multicentre cohort study including all
Hippocampal extracellular levels of noradrenaline (NA), 5-hydroxytryptamine (5-HT), and 5-hydroxyindoleacetic acid (5-HIAA) were monitored with the microdialysis technique in freely moving rats. In one experiment 30 min samples were collected during 24 h of continuous perfusion, and the monoamine output was compared to the behavioural activity state, as arbitrarily classified in three categories:
The objective of this study has been to create an online system for condition monitoring and diagnosis for a combined heat- and power plant in Sweden. This system consists of artificial neural network models, representing each main component of the combined heat- and power plant, accompanied with a graphical user interface. The artificial neural network models are integrated on a power generation
