Introduction: When in need of emergency care and ambulance services, the ambulance nurse is often the first point of contact for the patient with healthcare. This role requires comprehensive knowledge of the ambulance nurse to be able to assign the right level of care and, if necessary, to provide self-care advice for patients with no further conveyance to hospital. Recently, an application was de

This paper investigates how multiple in-cycle closed-loop combustion controllers can be integrated for a seamless operation under a wide-range of operating conditions. The stochastic cyclic variations of the combustion can be successfully compensated by the adjustment of the fuel injection pulses within the same cycle. The feedback information and controllability obtained relies on the different o

This paper investigates the quantification of FPGA resources for the implementation of closed-loop combustion control algorithms. Specifically, the study focuses on methods for their in-cycle execution and control of the combustion in real-time. A National Instruments Xilinx Virtex-5 platform was used for the quantification of the resources.Closed-loop combustion control obtains feedback from fast

The generation of hydrogel droplets using droplet microfluidics has emerged as a powerful tool with many applications in biology and medicine. Here, a microfluidic system to control the position of particles (beads or astrocyte cells) in hydrogel droplets using bulk acoustic standing waves is presented. The chip consisted of a droplet generator and a 380 µm wide acoustic focusing channel. Droplets

This paper is a comprehensive review of in-cycle closed-loop combustion controllers to achieve higher indicated efficiencies. Closed-loop combustion control reduces the effect of external disturbances and system uncertainties, which permit tighter safety margins and robust operation with a reduced calibration effort. The paper combines different components of previous investigations by the authors

Global warming may prolong and intensify the thermal growing season of vegetation. It is not yet clear how the Paris Agreement's long-term temperature goals will affect the thermal growing season of vegetation, particularly crops, in China. Based on the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) datasets and the Global Gridded Crop Model Intercomparison (GGCMI) phase 1 dataset, w

Laminar burning velocities of propionic acid + air flames have been determined using the heat flux method at atmospheric pressure and initial gas mixture temperature of 348 K over the range of equivalence ratios 0.7–1.3. The detailed kinetic model of the authors was extended by the reactions of propionic acid and its intermediates. Attention has been paid to the proper description of the formation

Ett samhälle med ökande behov av transporttjänster och stort behov av minskade växthusgasutsläpp måste bryta sitt beroende av fossila bränslen. Introduktionen av alternativa, elektrifierade, fordonsdrivlinor kräver tekniska lösningar och långsiktiga ekonomiska investeringar som inte finns än. Samtidigt ökar efterfrågan på förbränningsmotorbaserade drivlinor, eftersom de på ett tillförlitligt och eWith the increasing demand of transportation, biofuels play a fundamental role in the transition to sustainable powertrains. For the increased uncertainty of biofuel combustion properties, advanced combustion control systems have the potential to operate the engine with high flexibility while maintaining a high efficiency and robustness. For that purpose, this thesis investigates the analysis, des

Encapsulation of Lactobacillus reuteri in the internal aqueous phase of W1/O/W2 emulsions was investigated. Microstructure of the emulsions was evaluated using a particle size analyzer and light microscopy. The encapsulation properties were evaluated in terms of encapsulation efficiency (EE) for freshly prepared samples and encapsulation stability (ES) during storage and in vitro digestion and the

Terrestrial water storage (TWS) is a crucial indicator of regional water balance and water resources changes. Due to limited hydrological observations, we combined the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (GRACE-FO) products using the Long Short-Term Memory (LSTM) neural network to monitor the TWS changes from April 2002 to March 2020 over the closed Qaidam Basin in

In this paper we consider distributed adaptive stabilization for uncertain multivariable linear systems with a time-varying diagonal matrix gain. We show that uncertain multivariable linear systems are stabilizable by diagonal matrix high gains if the system matrix is an H-matrix with positive diagonal entries. Based on matrix measure and stability theory for diagonally dominant systems, we consid

Noctuidae are one of the world's most diverse, ecologically successful, and economically important animal lineages with over 12,000 species in ∼1,150 genera. We inferred a phylogeny using eight protein-coding genes for the global fauna, greatly expanding upon previous attempts to stabilize Noctuidae higher classification by sampling 341 genera (nearly half represented by their type species) repres

Heat load forecasts are crucial for energy operators in order to optimize the energy production at district heating plants for the coming hours. Furthermore, forecasts of heat load are needed for optimized control of the district heating network since a lower temperature reduces the heat loss, but the required heat supply at the end-users puts a lower limit on the temperature level. Consequently,

This study explored the depth treatment of desphenly chloridazon (DPC) wastewater by a novel synergetic dual-electrodes electrocatalytic (SDEs) system which consisted of Ni–Sb–SnO2/Ti anode (NSSTA) and PEDOT/PSS-CNTs modified activated carbon air diffusion cathode (PP-CNTs AC ADC). NSSTA exhibited an enhanced capability to produce reactive oxygen species (·OH and O3), its O3 production increased t

It has been known for a long time that older adults suffer a significantly higher risk of dying in residential fires compared to younger people. The characteristics of these fatal fires and the fatalities are also well known. However, less is known about older adults who survive fires and how they differ from those who die. This distinction can be assumed to be of great importance when designing e

This paper studies the use of predictive in-cycle close-loop combustion control to reduce the stochastic cyclic variations of diesel combustion. The combustion metrics that fully define the pressure trace with a pilot-main injection i.e. pilot and main start of combustion, burned pilot mass, and engine load are used as the set-point reference. These metrics are in-cycle predicted by calibrated mod

The externalizing spectrum, including traits and behaviors such as aggression, reduced inhibitiory control and substance abuse, is associated with altered prefrontal brain morphology. However, the degree to which different manifestations of the externalizing spectrum are associated with distinct or overlapping variations in individual brain morphology is unclear. Here, we therefore used structural

Endotherms in cold regions improve heat-producing capacity when preparing for winter. We know comparatively little about how this change is fueled by seasonal adaptation in cellular respiration. Thus, we studied the changes of mitochondrial function in red blood cells in sympatric Coal (Periparus ater), Blue (Cyanistes caeruleus), and Great (Parus major) tits between autumn and winter. These speci

Hematopoiesis serves as a paradigm for how homeostasis is maintained within hierarchically organized cell populations. However, important questions remain as to the contribution of hematopoietic stem cells (HSCs) toward maintaining steady state hematopoiesis. A number of in vivo lineage labeling and propagation studies have given rise to contradictory interpretations, leaving key properties of ste
