Molecular and Serologic Diagnostic Technologies for SARS-CoV-2

The COVID-19 pandemic has presented many challenges that have spurred biotechnological research to address specific problems. Diagnostics is one area where biotechnology has been critical. Diagnostic tests play a vital role in managing a viral threat by facilitating the detection of infected and/or recovered individuals. From the perspective of what information is provided, these tests fall into t

Evaluating Swedish soldiers’ physiological demands in combat

Att vara soldat är väldigt fysiskt krävande, det viktigt att upprätthålla en god fysisk kapacitetsnivå för att klara sin tjänst. Vid militära operationer arbetar soldater på lägre fysiska kravnivåer under lång tid för att ibland gå upp på intensiva kravnivåer. Framgång vid militära operationer är ofta beroende på soldaternas fysiska kapacitet, rörlighet och förmågan att bära sin utrustning. Det är

Nonlinear mechanical behaviour and analysis of wood and fibre materials

The mechanical behaviour of wood was studied from a micro up to a macro level. Wood is a cellular material possessing a high degree of anisotropy. Like other cellular solids, it often exhibits a highly nonlinear stress–strain behaviour. In the present study the mechanical properties of the cellular structure of wood are characterized and modelled, the irregular cell shape, the anisotropic layered The mechanical behaviour of wood was studied from a micro up to a macro level.

Stimulus-dependent orientation strategies in monarch butterflies

Insects are well known for their ability to keep track of their heading direction based on a combination of skylight cues and visual landmarks. This allows them to navigate back to their nest, disperse throughout unfamiliar environments, as well as migrate over large distances between their breeding and non-breeding habitats. The monarch butterfly (Danaus plexippus), for instance, is known for its

Adaptive Dual Control Methods: An Overview

This paper gives an overview of different techniques for solving the dual control problem. The optimal solution can quite straightforwardly be characterized. The solution is, however, numerically demanding. A large number of suboptimal dual controllers have been developed over the years and the paper gives an overview and discussion of different approaches.

Användning av CEQ:s TM-skala för projektbaserade kurser

Skalan Tydliga mål (TM) i Course Evaluation Questionnaire (CEQ, en kursutvärderingsenkät som ges vid Lunds Tekniska Högskola), mäter hur väl lärarna kommunicerar kursens lärandemål och vad de förväntar sig att studenterna ska prestera för att uppfylla lärandemålen. Projektbaserade kurser har en form av examination – pro- jektet – som inte är vanlig för studenterna och där tydlighe

Addressing Housing Needs of the Displaced People Promoting Resilient and Sustainable Communities

Addressing the housing needs of the displaced communities is an essential part of a recovery programme that has distinct links to livelihoods, health, education, security and social and family stability. The housing factor acts as a social centre for family and friends, a source of pride and cultural identity and a resource that commands both political and economic importance. Therefore, addressin

Adaptive extremal control

In this paper extrema1 control of a simple nonlinear stochastic system is analyzed. The process is modeled as a generalized Hammerstein model. Different problem formulations are discussed and the performances of the resulting nonlinear adaptive controllers are investigated. The adaptive controllers are based on on-line estimation of the parameters of the process and the certainty equivalence princ

Palliative care delivery at nursing homes before and after an educational intervention from professionals' perspective : A pre-post design

BACKGROUND: The principles of palliative care were developed in hospices and specialised palliative care units and have not been sufficiently adapted to and evaluated in nursing homes. Therefore, an educational intervention from an interprofessional education perspective was performed within the project Implementation of Knowledge-Based Palliative Care in Nursing Homes. The aim of this study was t

MICROPLASTICS IN LANDFILL LEACHATES IN THREE NORDIC COUNTRIES

We investigated the occurrence of microplastics (size range 5,000-50 µm) in leach-ates at 11 landfills of different age and operational status in Finland, Iceland and Nor-way. Collective sampling was carried out by pumping leachate with a stainless-steel submergible pump through a custom-made, stainless-steel filter unit containing filter plates with decreasing pore sizes (5,000, 417 and 47 µm, re

Pandemic responses at the subnational level : Exploring politics, administration, and politicization in Swedish municipalities

The Swedish response to the pandemic at the national level has attracted considerable international attention, but little focus has been placed on the way municipalities dealt with the crisis. Using Hay's dimensions of politicization, namely the capacity for human agency, deliberation in the public domain, and social context, we analyze the politicization of the municipal response to the pandemic

Developing a Porcine Model to Study the Glymphatic System

The glymphatic system is a brain-wide solute clearance system that has developed in the brain to clear metabolic waste during sleep. This clearance is mediated by advective fluxes of cerebrospinal fluid (CSF) along perivascular spaces (PVS) and through the brain. The movement of CSF from the PVS and through the brain is dependent on the polarised expression of aquaporin-4 (AQP4) at astrocyte endfe

Deep-Learning Based Channel Estimation for OFDM Wireless Communications

Multi-carrier technique is a backbone for modern commercial networks. However, the performances of multi-carrier systems in general depend greatly on the qualities of acquired channel state information (CSI). In this paper, we propose a novel deep-learning based processing pipeline to estimate CSI for payload time-frequency resource elements. The proposed pipeline contains two cascaded subblocks,

Omställning till elbussar i svenska städer : Lärdomar om affärsmodeller, ägarskap och upphandling

Stadsbusstrafiken genomgår just nu en förändring där elbussar introduceras i snabb takt. Medan elbussar för några år sedan mestadels förekom i olika test- och pilotprojekt rullar det våren 2022 över 600 elbussar i ordinarie linjelagd kollektivtrafik i ca 25 olika svenska städer. Omställningen till elbussar karaktäriseras bland annat av att man gjort olika val avseende tillverkare och olika val avs
