Introduction: In this cohort study, we evaluated whether the particles in exhaled air (PExA) device can be used in conjunction with mechanical ventilation during surgery. The PExA device consists of an optical particle counter and an impactor that collects particles in exhaled air. Our aim was to establish the feasibility of the PExA device in combination with mechanical ventilation (MV) during su

In this article we present a new method for visual face tracking that is carried out in wavelet subspace. Firstly, a waveletre presentation for the face template is created, which spans a low dimensional subspace of the image space. The wavelet representation of the face is a point in this wavelet subspace. The video sequence frames in which the face is tracked are orthogonally projected into this

There is still a lack of pharmacological treatment options for traumatic brain injury (TBI), the dominant cause of death and disability in persons under the age of 40 in the developed part of the world. Clinical TBI is a markedly complex disease, categorized into different subtypes that differ in their pathophysiology, treatment requirements, and long-term consequences. For successful development

Maf transcription factors are critical regulators of beta-cell function. We have previously shown that reduced MafA expression in human and mouse islets is associated with a pro-inflammatory gene signature. Here, we investigate if the loss of Maf transcription factors induced autoimmune processes in the pancreas. Transcriptomics analysis showed expression of pro-inflammatory as well as immune cell

The main objective for this article is to explore how users of psychoactive drugs experience time and the role psychoactive drugs play in the management and construction of time. The data in this study consists of different kinds of written documents such as anecdotal accounts and scientific articles and reports which was collected using a purposeful sampling technique. One important result is tha

The presence of graphite particles in gray cast iron commonly implies a good machinability, especially if compared to common steels. However, increasing industrial demands have resulted in a new interest for high-speed machining of these materials with higher performing tool materials than the traditionally used. Thus, the research presented in this paper focuses on evaluating the active tool wear

Gas turbine systems are predominantly designed to be fuelled with gaseous fuels within a limited Wobbe index range (typically HHV=45-55 MJ/Nm3 or 1200-1480 Btu/scf). When low calorific fuel gases are fired, the engine will be forced to operate outside its design envelope. The added mass flow will typically raise the cycle pressure ratio and in two-shaft designs also raise the gas generator shaft s

Detta arbete kick-startar AI (artificiell intelligens) för ledningsunderhåll i VA-branschen i Sverige. Arbetet med befintliga VA-nät är idag främst reaktivt; man reparerar läckor vartefter man blir varse dem, ibland till stora kostnader om läckan är omfattande och akut. Med denna artikel vill vi sätta fokus på proaktivt arbete med ledningsnät och diskutera riskanalys inom området. En ANN-modell soThis work kick-starts AI (artificial intelligence) for pipe management among Swedish water utilities. The current work with pipe management is mainly reactive; leaks are repaired after they are detected, sometimes with large costs if the leakage is extensive and critical. With this article, we want to focus on proactive pipe network management and discuss risk analysis in the field. A previously d

BACKGROUND: Preoperative radiological assessment of meningioma characteristics is of value for pre- and post-operative patient management, counselling, and surgical approach.PURPOSE: To investigate whether tensor-valued diffusion MRI can add to the preoperative prediction of meningioma consistency, grade and type.MATERIALS AND METHODS: 30 patients with intracranial meningiomas (22 WHO grade I, 8 W

Aims: To describe and compare perceptions of collaboration between care providers on the part of three groups of Registered Nurses working in municipal care and having particular responsibility concerning the care of frail older people with intellectual disability (ID); and, furthermore, to investigate the presence of and compliance with guidelines for the coordination of care. Design: National su

When training a deep learning model, the dataset used is of great importance to make sure that the model learns relevant features of the data and that it will be able to generalize to new data. However, it is typically difficult to produce a dataset without some bias toward any specific feature. Deep learning models used in histopathology have a tendency to overfit to the stain appearance of the t

This cross-country study investigates the potential to improve pig welfare by exploiting consumer demand, domestically and in export markets, for welfare pork produced in indoor production systems. The analysis is based on questionnaire data collected in 2019 focusing on demand for Danish welfare pork both in Denmark and in two nearby export markets, Sweden and Germany. To reduce hypothetical bias

The visual environment has an impact on subjective strain and headaches. A visual ergonomics risk assessment method, VERAM, was used on 217 workplaces, and consists of both of a subjective questionnaire and an objective risk assessment, the objective risks are presented in this paper. The risk for daylight was assessed to be yellow (risk) or red (high risk) at 53% of the workplaces and the risk fo
