The need and benefits of new universal mathematical and especially algebraic and operator structures and methods in all branches and levels of modem physics from experiments to fundamentals is nowdays widely recognized. The far reaching pioneering discoveries of R. M. Santilli extend significantly the Lie analysis and operator methods and models of modem physics opening new areas of applications w
Hypothesis: Sodium dioctylsulfosuccinate (Aerosol OT or NaAOT) is a well-studied charging agent for model poly(methyl methacrylate) (PMMA) latexes dispersed in nonpolar alkane solvents. Despite this,few controlled variations have been made to the molecular structure. A series of counterion exchanged analogs of NaAOT with other alkali metals (lithium, potassium, rubidium, and cesium) were prepared,
Objectives This systematic review aimed to identify published observational methods assessing biomechanical exposures in occupational settings and evaluate them with reference to the needs of different users. Methods We searched scientific databases and the internet for material from 1965 to September 2008. Methods were included if they were primarily based on the systematic observation of work, t
Acute effects of air pollution on respiratory health have traditionally been investigated with data on inpatient admissions, emergency room visits, and mortality. In this study, we aim to describe the total acute effects of air pollution on health care use for respiratory symptoms (ICD10-J00-J99). This will be done by investigating primary health care (PHC) visits, inpatient admissions, and emerge
According to Boveri's hypothesis, chromosome abnormalities were the cellular changes causing the transition from normal to malignant proliferation. Technical difficulties prevented reliable visualization of mammalian chromosomes, in both normal and neoplastic cells, throughout the entire first half of the 20th century. Nowell and Hungerford's discovery greatly stimulated interest in cancer cytogen
Stars in open clusters are expected to share an identical abundance pattern. Establishing the level of chemical homogeneity in a given open cluster deserves further study as it is the basis of the concept of chemical tagging to unravel the history of theMilkyWay.M67 is particularly interesting given its solar metallicity and age as well as being a dense cluster environment.We conducted a strictly
Connecting the complementary facilities MAX IV & ESS with DESY & European X-FEL creates synergy and a globally unique infrastructure region with fantastic opportunities for innovation and research not least in Life Science. Through Hanseatic League of Science (HALOS) the Life Science research and innovation ecosystems is given a joint platform to take advantage of the facilities and a tool
The objective is to study the effect of high voltage pulses on living cells to find the most effective combination of physical parameters to be used in tumour therapy. Four parameters that affect the cell survival are the pulse shape, electric field strength, pulse length and the number of pulses and their cell killing effect were investigated in this work. High voltage square wave or exponentiall
Hypothesis: Nitric oxide (NO)-releasing Pluronic F127 hydrogels (F127) containing dissolved S-nitrosothiols or pendant N-diazeniumdiolate (NONOate) groups have been described. The NO charging of these hydrogels is usually limited by their low stability or disruption of the micellar packing. S-nitrosothiol-terminated F127 may emerge as a new strategy for allowing NO delivery at different rates in b
Are people more likely to become more politically active through social media when they observe that their friends are active? Previous research has shown that an individual's likelihood of engaging politically is influenced by observations of how friends act through social media, but relatively little is known about how such social influence through social media interacts with personality feature
Wild geese are increasing in agricultural and urban settings across Europe, leading to widespread human–geese interactions. This study examined how the public’s acceptance of geese (attitude and acceptance capacity) varied depending on place dimensions, interactions with geese in different settings (place-based experience), and psychological factors, including wildlife value orientations, beliefs
Background: National guidelines are important instruments in reducing inappropriate antibiotic prescriptions. Low adherence to guidelines is an acknowledged problem that needs to be addressed. Method: We evaluated established characteristics for guidelines in the guidelines for lower respiratory tract infection, acute otitis media and pharyngotonsillitis in primary care. We studied how doctors use
Vi vill med den här artikeln peka på att Sveriges städer har flera utmaningar kring styrning och hantering av vatten, samt föreslår sju principer för lösningar. Klimatförändringarna och den urbana tillväxten gör att åtgärder behövs nu för att hantera både vattenbrist och översvämning på ett integrerat sätt. Här fokuserar vi på kommunnivå och urbana områden, där vi argumenterar för att det behövs eWe argue in this paper that Swedish urban areas have several urgent challenges when it comes to water governance and we propose seven principles for addressing them. Climate change and urban growth call for swift action to manage both water scarcity and flooding in an integrated way. This paper focuses on the municipal level for which we argue that there is a need for a more systematic approach. T
CONTEXT: Once islet autoantibody-positive individuals are identified, predicting which individuals are at highest risk for type 1 diabetes (T1D) is important. A metabolic risk score derived from 2-hour oral glucose tolerance test (OGTT) data, the Diabetes Prevention Trial-Type 1 risk score (DPTRS), can accurately predict T1D. However, 2-hour OGTTs are time-consuming and costly. OBJECTIVE: We aimed
Oestrogen receptor β (ERβ) has been suggested to have anti-proliferative and anti-tumour effects in breast and prostate cancer cells, but other studies have indicated its tumour-promoting effects. Understanding the complex effects of this receptor in different contexts requires further study. We reported that high ERβ expression is independently associated with improved prognosis in female colorec
Background: More women in reproductive ages are entering occupations where exposure to whole body vibrations (WBV) is common (e.g. in transportation and construction). Previous studies based on self-assessed exposure suggest increased risks of adverse birth outcomes, but it is unclear at what exposure levels and if the current exposure guidelines are appropriate during pregnancy. Objectives: To in
This paper presents a deep learning algorithm for tomographic reconstruction (GANrec). The algorithm uses a generative adversarial network (GAN) to solve the inverse of the Radon transform directly. It works for independent sinograms without additional training steps. The GAN has been developed to fit the input sinogram with the model sinogram generated from the predicted reconstruction. Good qual
Structural monitoring (e.g. structural measurement and damage detection) and inspections have been widely applied as part of structural maintenance. However, the potential of using the obtained information is not yet fully exploited to update the structural reliability and support the maintenance and operation strategy. This paper describes the foundations, limitations, and characteristics of meas
