Introduction: Divers are reported to have a lower ventilatory response to elevated levels of carbon dioxide (CO₂) than non-divers. Hypoventilation with CO₂ retention during diving is potentially dangerous. It is unknown if CO₂ retention is largely inherited or develops during diving training. We aimed to investigate if a military dive training course would influence the ventilatory response to CO₂
Growth and immune development—fundamental parts of any organism's ontogeny—depend critically on nutrient availability, particularly on essential amino acids that support protein synthesis and physiological processes. However, environmental variation can reduce prey diversity and nutrient quality, producing suboptimal diets that lack essential amino acids, potentially constraining development. In t
Background: Physiologically guided revascularization improves clinical outcomes. The cutoff values for deferral with fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are the same across all coronary arteries, despite differences in coronary flow patterns. The objective was to compare deferral rates using either FFR or iFR in the right coronary artery (RCA), left anterior desce
Background: Previous studies suggest an antidepressant effect of omega-3 fatty acids (n-3 PUFAs). This effect may be larger in patients with low-grade inflammation, defined as mild elevations of high sensitivity C-reactive protein or other commonly used inflammatory markers. The antidepressant mechanisms of n-3 PUFAs are not fully understood but may involve modulation of immunometabolic processes
We have used approximately 40 fs pulses from a Ti:sapphire laser to investigate the ultrafast energy transfer and relaxation dynamics in the light-harvesting pigment-proteins of photosynthetic purple bacteria. Our results reveal two new features, not earlier observed in light-harvesting pigments: (1) ultrafast relaxation characterized by a time constant of approximately 20 fs, which we interpret a
In the Swedish context, ‘intergenerational Collaborative Housing’ and ‘Collaborative Housing for the second half of life’ (CH2L), based on the self-work model, were developed in the 1980s and 1990s. The chapter examines how ageing individuals developed caring practices and mutual support strategies in these collective housing forms and how such practices were adapted during the COVID-19 pandemic.
Wireless access technologies such as UMTS with HSPA extensions, WiMAX, and Flash-OFDM and the convergence towards next generation heterogeneous networks enable the realization of always best connected scenarios. As the resulting heterogeneous networks become easier to access and more reliable to depend on, novel telemedicine services such as vehicular emergency applications emerge. Due to their li
Generative product design systems used in the context of mass customization are required to generate diverse solutions quickly and reliably without necessitating modification or tuning during use. When such systems are employed to allow for the mass customization of product form, they must be able to handle mass production and engineering constraints that can be time-consuming to evaluate and diff
Popular Abstract in Swedish De svenska framtidsuttrycken (futuralt presens, futuralt skola och futuralt komma) är alla kontextuellt betingade användningar av uttryck som också har andra funktioner. Syftet med min avhandling är att beskriva vilka kontextvillkor som måste vara uppfyllda för att de tre uttrycken ska fungera som framtidsuttryck. I den modell över svenskans temporala system som presentThe main aim of this study is to specify the contextual conditions that apply to the use of the three central expressions for the future in Swedish: the present form and the auxiliaries skola and komma. A tense suffix indicates a temporal domain and states that a mediating element, here called FIX, is placed in the indicated domain. The present suffix points to a domain that overlaps temporally wi
Psychiatric, physical and biological aspects of posttraumatic stress disorder (PTSD) may be associated with dysfunctions in several cellular processes including nitric oxide (NO) production. NO is synthesized from arginine in a reaction carried out by NO synthase (NOS) enzymes. The recently introduced "global arginine bioavailability ratio" (GABR; ratio of arginine to [ornithine+ citrulline]) has
Surface temperature in internal combustion engines is of high interest when studying heat losses. Two approaches for retrieving the surface temperatures are thermocouples and Laser Induced Phosphorescence, LIP. This study aims to analyze LIP as a technique for measuring surface temperature in internal combustion engines. The motivation for this study is the need for accurate surface temperatures w
This paper describes a novel tool for eliciting user requirements early in the design process of mobile applications. The “Mobile Oracle”, as we have called it, is intended to help developers and designers obtain a better understanding of what the user wants at different points in space and time. It is an extension of a lo-fi version of the well-established Wizard of Oz technique, but it also adds
BACKGROUND: Increased intraocular pressure (IOP) has been shown to be one of the most important risk factors for developing glaucoma. Yet it has not been clearly demonstrated that IOP-lowering treatment can reduce the incidence of glaucoma damage in patients with ocular hypertension. The aim of the current paper was to report the results of a long-term study addressing this very problem.METHODS: W
Many amputees have maps of referred sensation from their missing hand on their residual limb (phantom maps). This skin area can serve as a target for providing amputees with tactile sensory feedback. Providing tactile feedback on the phantom map can improve the object manipulation ability, enhance embodiment of myoelectric prostheses users and help reduce phantom limb pain. The distribution of the
Water and salt mass balances for the Dead Sea were modeled. Precipitation, evaporation, river discharges, ground water flows, input/output from potash companies and salt production, and brine discharge were included in the models. The mixing time in the Dead Sea was modeled using a single-layer (well-mixed) atwo-layer (stratified) system.Using the single-layer approach the water level was predicte
Aims: Infectious complications frequently occur in intensive care unit patients admitted after out-of-hospital cardiac arrest. There is debate on the effects of temperature management on the incidence of infections, as well as on the efficacy and choice of antibiotic prophylaxis. In this substudy of the targeted temperature management (TTM) trial, we describe the microbiological profile of infecti
Modern vibrational spectroscopy techniques enable the rapid collection of thousands of spectra in a single hyperspectral image, allowing researchers to study spatially heterogeneous samples at micrometer resolution. A number of algorithms have been developed to correct for effects such as atmospheric absorption, light scattering by cellular structures and varying baseline levels. After preprocessi
