The Harmattan is a dry dust-laden continental wind, and in the boreal winter Harmattan dust plumes affects many West African countries, including Ghana. When the Harmattan is strongest the southern part of Ghana is affected by the Inter Tropical Discontinuity (ITD). In this study, we investigate if the ITD functions as a barrier, preventing long transported Harmattan dust to settle south of, and b
One of the primary challenges of the Water Framework Directive (WFD) of the European Union is to provide a guide for the recovery of surface waters from pollution. However, few studies deal with reference conditions according to the WFD in coastal waters. Using the urbanised Laajalahti Bay (Helsinki, Finland) as an example, reference conditions and pollution history were defined using the stratigr
BACKGROUND: Microarray experiments are increasing in size and samples are collected asynchronously over long time. Available data are re-analysed as more samples are hybridized. Systematic use of collected data requires tracking of biomaterials, array information, raw data, and assembly of annotations. To meet the information tracking and data analysis challenges in microarray experiments we reimp
The EMPOST-NET project studied a new phenomenon: networking across different public and private sectors of society towards the most important goal of today – sustainable development. Sustainability networks are of special importance within the field of tourism, which is among the largest industries of today’s world, yet its environmental and socio-cultural impacts are often given too little attent
The importance of the nurse's role in the management of patients with type 2 diabetes has long since been emphasized. The aim of this study was to test the hypothesis that a structured organization of type 2 diabetes care, with a diabetes nurse working more independently of the general practitioner, has a significant impact on the patient's self-management and quality of care. The test consisted o
BACKGROUND: As rheumatoid arthritis (RA) occurs more often in women than in men, it has been suggested that reproductive hormones may play an important role in the pathogenesis.METHODS: Between 1991 and 1996, 30 447 subjects (18 326 women) were included in a community-based health survey. Information on female hormonal changes and stress-related factors was obtained using a self-administered quest
This article reports model experiments where vocal tract profiles of high and mid unrounded front and high rounded back vowels were systematically modified to simulate small constriction shifts along the hard or soft palate, in order to test A. M. Bell's century-old proposal that small shifts of tongue arch fronting or retraction would yield audible shifts of vowel timbre. Such differences were cl
The studies presented in this thesis concern hydronic space heating systems connected via heat exchangers to a district heating network: referred to as an indirect connection. The objective has been to improve the reliability of district heat supplies and to lower the return temperature from consumer substations. Two of the disadvantages of an indirect connection have been addressed: the thermodyn
The aim of this study was to investigate torso cooling benefit of various PCM vests in a simulated warm environment (Ta= 34 °C, RH=56 %, Va=0.4 m/s). A pre-wetted cotton torso fabric skin was used to simulate sweating on a thermal manikin (Tmanikin=34 °C). Six conditions were tested: nude fabric skin (Fabric Skin), Vest A without (VA) and with frozen gels with a melting temperature (Tm) of 0 °C (V
Previous research has consistently found demographic responses to grain price fluctuations in preindustrial Europe, both at macro and micro level. Grain prices serve as a summary measure of the workings of the preindustrial economy, reflecting not only local harvest conditions but trade patterns and market integration. All over preindustrial Europe the manorial estate was an important institution
The present thesis reports on results from the fabrication technology development and the corresponding electrical transport measurements of low-dimensional semiconductor structures. The focus of the work has been directed towards two parts: the ballistic transport in nanostructure devices at room temperature, and the development of a charge-sensing technique for quantum dots (QD) in nanowires. B
This thesis examines genetic variation in allotetraploids of the Dactylorhiza incarnata/maculata polyploid complex in different parts of Europe. The molecular markers used were AFLPs, allozymes, ITS, nuclear microsatellites and plastid DNA markers. The results showed that the Alps and Greece have served as refugia for the genus during Pleistocene glaciations. Immigration routes of D. majalis ssp.
Reconstruction of movement control properties of the brain could result in many potential advantages for application in robotics. However, a hampering factor so far has been the lack of knowledge of the structure and function of brain circuitry in vivo during movement control. Much more detailed information has recently become available for the area of the cerebellum that controls arm-hand movemen
Microscopy and particle-based simulations are both powerful techniques to study aggregated particulate matter such as colloidal gels. The data provided by these techniques often contains information on a wide array of length scales, but structural analysis methods typically focus on the local particle arrangement, even though the data also contains information about the particle network on the mes
Objective: Parastomal hernia (PH) in association with an ileal conduit is a common complication that is difficult to treat. Mesh reinforcement has been suggested to improve outcomes; either as prophylaxis or for treatment of a parastomal hernia during abdominal wall reconstruction. Patients and methods: A retrospective study was performed in consecutive patients subjected to mesh implantation betw
Aims Lung cancer predictive biomarker testing is essential to select advanced-stage patients for targeted treatments and should be carried out without delays even during health emergencies, such as the coronavirus (COVID-19) outbreak. Methods Fifteen molecular laboratories from seven different European countries compared 4 weeks of national lockdown to a corresponding period in 2019, in terms of t
For successful climate change adaptation, the distribution of responsibility within society is an important question. While the literature highlights the need for involving both public and private actors, little is still known of how citizens perceive their own and others’ responsibility, let alone the moral groundings for such perceptions. In this paper, we report the results of a survey regardin
We establish quantitative results for the statistical behaviour of infinite systems. We consider two kinds of infinite system: i) a conservative dynamical system (f, X, µ) preserving a σ-finite measure µ such that µ(X) = ∞; ii) the case where µ is a probability measure but we consider the statistical behaviour of an observable φ: X → [0, ∞) which is non-integrable: R φ dµ = ∞. In the first part of
