A highly scattering porous ceramic sample is employed as a miniature random-scattering multipass gas cell for monitoring of oxygen content in opaque media, that is, wood materials in the present work. Gas in scattering media absorption spectroscopy is used by employing a 760 nm near-infrared laser diode to probe the absorption of molecular oxygen enclosed in the pores of the ceramic material worki
Conducting social-ecological system (SES) research in fisheries aimed at aiding the implementation of a management plan that achieves sustainable outcomes remains a significant challenge. Using the Ostrom (2009) [1] diagnostic SES framework is widely utilized and acknowledged as an integral tool for research on SESs. The purpose of this article is to highlight and illustrate a comprehensive and ho
Introduction: Acquired AmpC enzymes, classified as miscellaneous extended-spectrum beta-lactamase (ESBLM) enzymes according to a recently proposed beta-lactamase classification, are increasing according to several publications. Simple and rapid methods for detection of ESBLM are needed for appropriate infection control. A gel-based multiplex PCR method for acquired bla(AmpC) detection and subtype
In this study we describe a novel flow-through respirometer with automated and semi-continuous detection of key water variables. The recirculating aquaculture system was designed to house aquatic organisms in culture-like conditions and allow long-term, high-precision measurements. Nine respirometry tanks (250 L in volume each) housed animals, and a tenth (without animals) acted as a reference tan
The choice of anaesthetic technique for patients undergoing joint arthroplasty is debatable. The hypothesis of this study was that general anaesthesia would generate a more favourable recovery profile than spinal anaesthesia.
Several gene expression-based prognostic signatures have been described in neuroblastoma, but none have successfully been applied in the clinic. Here we have developed a clinically applicable prognostic gene signature, both with regards to number of genes and analysis platform. Importantly, it does not require comparison between patients and is applicable amongst high-risk patients. The signature
Palovarotene is an oral gamma-selective retinoid agonist. In animal emphysema models, palovarotene reduced inflammation, promoted structural repair and functional improvement. REPAIR (Retinoid treatment of Emphysema in Patients on the alpha(1)-antitrypsin International Registry), was an investigator-initiated, double-blind, placebo-controlled randomised study to assess the safety and efficacy of 5
It is well known that in the context of the classical regression model with heteroskedastic errors, while ordinary least squares (OLS) is not efficient, the weighted least squares (WLS) and quasi-maximum likelihood (QML) estimators that utilize the information contained in the heteroskedasticity are. In the context of unit root testing with conditional heteroskedasticity, while intuition suggests
Hygrothermal simulation programs are commonly used by design engineers to analyse moisture performance of building envelopes. For ventilated assemblies, programs typically require the user to enter cavity ventilation rates. If such input data are not prepared on physical grounds, it can impair the quality of the simulation results. In earlier papers: (1) estimations of ventilation rates in experim
Elevated levels of tropospheric ozone can significantly impair the growth of crops. The reduced removal of CO2 by plants leads to higher atmospheric concentrations of CO2, enhancing radiative forcing. Ozone effects on economic yield, e. g. the grain yield of wheat (Triticum aestivum L.), are currently used to model effects on radiative forcing. However, changes in grain yield do not necessarily re
This thesis is divided into two parts in which two different aspects of the Large Hadron Collider (LHC) Project are discussed. The first part describes the design of a transition radiation tracker (TRT) for the inner detector in ATLAS. In particular, the barrel part was studied in detail. The barrel TRT consists of 52 544 1.5-m-long proportional tubes (straws), parallel to the beam axis and each
Proton exchange membrane fuel cell (PEMFC) systems have been investigated as alternative power sources for the stationary and automotive applications. However, they do not appear on the market yet. One of the main reasons is the difficulty of the water/thermal management in the system. Several water recovery schemes have been proposed to overcome this difficulty and to simplify the system configur
The increasing trend to build both more and longer underground transportation systems, e.g., road and rail tunnels, and the special characteristics of these facilities, introduces new problem areas to both fire safety designers and fire rescue services. TUFT, a simple computer model, has therefore been developed partly to aid fire safety designers in the early stages of the fire safety design proc
Search algorithms for regular and irregular quasi-cyclic LDPC block codes with both good girth profile and good degree distribution are presented. New QC LDPC block codes of various code rates are obtained and their bit error rate performance is compared with that of the corresponding LDPC block codes defined in the IEEE 802.16 WiMAX standard of the same block length and code rate.
This thesis aims to explore the meanings behind rural reading rooms (tushushi) in Yunnan Province, PRC. Rural reading rooms are small libraries attached to the village Party compound in Chinese villages; for the past decade 600 000 reading rooms have been established in administrative villages in China, and now benefit more than 1 billion farmers in what is arguably the world’s most important deve
Sustainability philosophers claim that we are at the impasse of stories, finding ourselves in a blank chapter between the old and the new. The old story, characterized by separation, technological arrogance and human superiority over nature, is unfolding in an ecological crisis giving space for a new narrative defined by inter being, cooperation and balance. It has been put forward that this crisi
The increasing quantity of disposal of single-use items has become one of the important causes of waste accumulation. Today, littering of packaging waste has many severe effects on the environment. As the EU has reported, curbing littering is a complex issue that needs to be tackled. Improving the way packaging is designed will help to deliver a lower level of littering and a higher level of recyc
