Hollow fiber supported liquid membrane sampling and speciation of lead(II) from aqueous solution using a selective carrier (Kelex 100) is studied. An optimization of different variables affecting permeation performance (chemical conditions of the sampling module - pH, concentration and nature of the acceptor phase, extractant concentration; membrane impregnation form; sampling time; and hollow fib
We have recently shown that there is a previous unknown longitudinal movement present in the arterial wall. We aim now to investigate whether the longitudinal movement causes length alteration of the arterial wall. The objective of this paper was to describe a new non-invasive ultrasonic technique that measures the length alteration of arteries in human in-vivo. Results indicate that a significant
The clinical classification of hereditary sequence variants identified in disease-related genes directly affects clinical management of patients and their relatives. The International Society for Gastrointestinal Hereditary Tumours (InSiGHT) undertook a collaborative effort to develop, test and apply a standardized classification scheme to constitutional variants in the Lynch syndrome-associated g
We describe quantum-size and binding-site effects on the chemical and local field enhancement mechanisms of surface-enhanced resonance Raman scattering (SERRS), in which the pyridine molecule is adsorbed on one of the vertices of the Ag-20 tetrahedron. We first investigated the influence of the binding site on normal Raman scattering (NRS) and excited state properties of optical absorption spectro
This paper presents the development of an experimentally validated model that mechanistically comprehends the complex interaction between the gas-phase fluid dynamics, the mass transport of individual species, and the heterogeneous gas-surface reaction mechanism in a continuous cross-flow atomic layer deposition (ALD) reactor. The developed ALD gas-surface reaction mechanism, purely based on conse
Background: Mycobacterium goodii is a rare cause of significant infection. M. goodii has mainly been associated with lymphadenitis, cellulitis, osteomyelitis, and wound infection. Case presentation: A case of a 76-year-old Caucasian female is presented. The patient developed a prosthetic valve endocarditis caused by M. goodii. She had also suffered from severe neurological symptoms related to a se
A portable high resolution soft x-ray and extreme ultraviolet (EUV) spectrometer has been developed for spectroscopic research at the Shanghai Electron Beam Ion Trap (EBIT) laboratory. A unique way of aligning the grazing incidence spectrometer using the zero order of the grating is introduced. This method is realized by extending the range of the movement of the CCD detector to cover the zero ord
Novel strategies for specific tumour cell targeting are necessary in order to improve survival rates and to reduce side effects of current therapies in cancer patients. Hypoxia is a hallmark of solid tumours and one of the major driving forces for tumour progression. Targeting of the adaptive responses of cancer cells to hypoxia offers opportunities for tumour specific therapies. The aim of this
Dizziness in older people is associated with disability and reduced quality of life. Few studies have investigated how daily life is affected from the older person's perspective. Identifying barriers and resources in daily life could guide health care in how to direct efficient interventions. The aim of this study was to explore older persons' experiences of living with chronic dizziness.
The aim of this thesis was to explore and gain deeper insight into and understanding of mobility in public environments for people with acquired cognitive functional limitations (target group of this thesis) and of reasons why some of them do not use public transport. Using an explorative approach, the target group’s mobility was firstly discussed by experts in focus group interviews. Secondly the
Urban green infrastructure (UGI) is gaining popularity for disaster risk reduction and climate change adaptation in urban contexts, but dense development obstructs the realisation of large-scale greening measures. This thesis investigates the potential of small-scale, site-specific urban greening in a residential area in Cologne, Germany, to improve ecosystem service supply. The objective is to as
The biomedical market is experiencing rapid growth, driven by the increasing volume of health data and the need for advanced technologies to manage and analyze this information. At the same time, the industry is facing additional challenges such as the shortage of healthcare professionals and an aging population. Artificial intelligence (AI) has the potential to become essential in this industry,
Article 17(1) of the Market Abuse Regulation (MAR) mandates that an issuer shall publicly disclose “inside information” which directly concerns the issuer as soon as possible, with the concept of “inside information” defined in art. 7 of MAR. This obligation is often referred to as the ad hoc disclosure requirement and it‘s perhaps the most crucial obligation issuers have to comply with when their
Based on the geopolitical situation in Europe and the European Union's (EU) initiative for further cooperation with its eastern neighborhood, this thesis analyzes the strategic interests behind the bilateral development aid allocation of the EU member states. The purpose is to, with a focus on aid directed to the Eastern Partnership states, provide the academic foreign aid field with a regiona
Meningsfull förändring är en central och djupt rotad strävan inom det psykoterapeutiska området. Terapeutens roll handlar om att hjälpa patienten att skapa förändring som är meningsfull för individen. Genom att mäta meningsfull förändring kan terapeuten se vilka interventioner som verkligen fungerar. Studien syftar till att utveckla och initialt utvärdera ett instrument för att mäta meningsfull föMeaningful change is a central and deeply rooted endeavor within psychotherapy. The study aims to develop and initially evaluate an instrument to measure meaningful change in psychotherapy. The therapist's role is to assist the patient in creating change that is meaningful to the individual. By measuring meaningful change, the therapist can identify which interventions are truly effective. The
Social media workers have become an important communication profession within the organisational context. However, workers behind organisational social media accounts remain understudied. This study problematises the limited emphasis of existing research on the self-perceptions of communication practitioners and introduces the perspective of social media workers. The purpose of this study is to ex
