Theoretical calculations of reaction kinetics were done for one‐step reactions catalyzed by cells immobilized in spherical beads. The reactions catalyzed by free cells were assumed to obey Michaelis–Menten kinetics for a one‐substrate reaction. Both external (outside the beads) and internal (inside the beads) mass transfer of the substrate were considered for the immobilized preparations. The theo
Flavor-changing neutral currents are not present in the Standard Model at tree level and are suppressed in loop processes by the unitarity of the Cabibbo-Kobayashi-Maskawa matrix; the corresponding rates for top quark decay processes are experimentally unobservable. Extensions of the Standard Model can generate new flavor-changing neutral current processes, leading to signals which, if observed, w
A search for new charged massive gauge bosons, W′, is performed with the ATLAS detector at the LHC. Data were collected in proton–proton collisions at a center-of-mass energy of s=13 TeV and correspond to an integrated luminosity of 36.1 fb−1. This analysis searches for W′ bosons in the W′→tb¯ decay channel in final states with an electron or muon plus jets. The search covers resonance masses betw
Populärvetenskaplig sammanfattningDet senaste århundradet har den tekniska utvecklingen gått snabbt inom många områden. Jordbruket är ett av dessa. Idag upptas ungefär en tredjedel av jordens landyta av jordbruk och boskapsskötsel. Utvecklingen av jordbruket har inneburit att vi idag kan producera mer mat än någonsin, men den har också inneburit intensivare brukningsmetoder, genom till exempel ökaAbstractHuman ingenuity and activities have resulted in erosion of ecosystems and their capacity to support the sustainable production of goods and functions that we depend on. Biodiversity i.e. the diversity within and between species and of ecosystems, underpins many of the ecosystem functions critical for human well-being and resilience, and is declining faster than at any time in human history
In recent years, Worldwide Interoperability for Microwave Access (WiMAX) has become an important technology providing wireless connections for mobile terminals in a wireless Metropolitan Area Network (MAN), due to its large radio range. In a MAN environment, wireless clients always have high mobility; therefore, it is possible that the mobile clients will move away from the service coverage of ser
We present a model for developing health services for men who have sex with men (MSM) in sub-Saharan Africa and other places where MSM are heavily stigmatized and marginalized. The processes of the SPEND model include Safe treatment for sexually transmissible infections (STIs) and HIV; Pharmacy sites for treatment of STIs in countries where pharmacies and drug stores are the source of medical advi
Syftet med foreliggande undersökning var att göra en utvärdering av en preliminär version av ett grammatiskt test som bygger på processabilitetsteorin (Pienemann, 1998) for att se hur väl det fungerar och for att ge forslag till eventuella omarbetningar infor det fortsatta arbetet med testet. Ytterligare ett syfte var att undersöka humvida processabilitetsteorins utvecklingsnivåer går att tillämpa
Background It has been hypothesised that the presence of health-damaging factors and lack of health-promoting factors lie in the causal pathway between neighbourhood deprivation and coronary heart disease (CHD). This study is the first to examine the associations between individual-level CHD risk and neighbourhood availability of fast-food restaurants, bars/pubs, physical activity facilities and h
IntroductionBeta-lactam antibiotics are essential in the treatment of Gram-negative bloodstream infections. The effect of beta-lactam antibiotics depends on the time of unbound antibiotic concentration above the minimal inhibitory concentration (MIC). An antibiotic concentration above MIC during the whole dosing interval (100% ƒT > MIC) has been suggested as a target for severe infections. The aim
Purpose: Childhood cancer survivors, in particular those treated with radiation therapy, are at high risk of long-term iatrogenic events. The prediction of risk of such events is mainly based on the knowledge of the radiation dose received to healthy organs and tissues during treatment of childhood cancer diagnosed decades ago. We aimed to set up a standardized organ dose table to help former pati
Background Evidence-based medicine recognizes that clinical expertise gained through experience is essential to good medical practice. However, it is not known what beliefs clinicians hold about how personal clinical experience and scientific knowledge contribute to their clinical decision making and how those beliefs vary between professions, which themselves vary along relevant characteristics, Background: Evidence-based medicine recognizes that clinical expertise gained through experience is essential to good medical practice.

The vector-boson production cross section for the Higgs boson decay in the Formula Presented channel is measured as a function of kinematic observables sensitive to the Higgs boson production and decay properties as well as integrated in a fiducial phase space. The analysis is performed using the proton-proton collision data collected by the ATLAS detector in Run 2 of the LHC at Formula Presented
Rapporten sammanfattar fjärilsinventeringar utförda 2020 inom Biogeografisk uppföljning som drivs av Naturvårdsverket. I fjällområdet kunde totalt 49 ytor inventeras. Sammanlagt noterades 151 högnordiska blåvingar på 22 inventerade ytor, 53 dvärgpärlemorfjärilar på 25 ytor och minst 1 fjällsilversmygare noterades på 3 inventerade ytor. Svartfläckig blåvinge observerades på 15 av 50 inventerade lok
This paper presents a search for hypothetical massive, charged, long-lived particles with the ATLAS detector at the LHC using an integrated luminosity of 139 fb−1 of proton–proton collisions at s = 13 TeV. These particles are expected to move significantly slower than the speed of light and should be identifiable by their high transverse momenta and anomalously large specific ionisation losses, dE
Objectives: We aimed to map the correlation between thermoluminescent dosimeters (TLDs) and Gafchromic film for measuring absorbed doses and to compare minimum, maximum, and mean absorbed doses over larger regions of interest and at various craniofacial organs and tissues during cone beam computed tomography (CBCT) exposure of the mandibular third molar region. Study Design: We positioned TLDs at
Background: Diseases of the bowel are not always displayed on conventional abdominal computed tomography (CT). The studied oral contrast agent aims to improve this. Purpose: To investigate whether the use of a novel oral contrast for abdominal CT enables the same diagnostic advantages as seen in magnetic resonance imaging (MRI). Material and Methods: Twenty-five consented volunteers drank up to 14
