Characterization of the "viable but nonculturable" (VBNC) state in the wine spoilage yeast Brettanomyces.

2012

Although the viable but not culturable (VBNC) state has been studied in detail in bacteria, it has been suggested that maintenance of viability with loss of culturability also exists in eukaryotic cells, such as in the wine spoilage yeast Brettanomyces. To provide conclusive evidence for the existence of a VBNC state in this yeast, we investigated its capacity to become viable and nonculturable after sulfite stress, and its ability to recover culturability after stressor removal. Sulfite addition induced loss of culturability but maintenance of viability. Increasing the medium pH to decrease the concentration of toxic SO(2) allowed yeast cells to become culturable again, thus demonstrating …

A critical analysis of the 'cooperative' strategy to poverty reduction : a case study of cooperatives in Lagos, Nigeria

2007

The aim of this thesis is to critically examine whether cooperatives can be effective at poverty reduction, in response to the renewed call for a cooperative strategy to poverty reduction. The thesis studied cooperatives as a social organization and examined the interrelationships between the cooperatives and the members, the factors that hold both together to promote and deter the success of the cooperatives, the motivation for members’ participation and their expectations from the cooperatives. These were then used to discuss and evaluate cooperatives as a poverty reduction strategy. The study followed an inductive method for data collection and analysis. Focus group discussions were held…

The effect of aquatic exercise on symptoms, function, body composition and cartilage in knee osteoarthritis

2016

Knee osteoarthritis (OA) is the most common joint disease associated with pain and loss of functional capacity. The management of knee OA is multifaceted and covers the whole OA continuum from injury prevention to the end stage of the disease. Recently, specific focus has been on preventing the progression of cartilage degeneration and avoiding loss of function in the early phase of the disease via the provision of exercise interventions. Aquatic exercise is a popular but under-researched exercise option. Therefore, the purpose of this dissertation was to investigate the role of aquatic exercise in the management of knee OA, focusing especially the effect it evokes on both functional capaci…

Lagrangian matches between observations from aircraft, lidar and radar in a warm conveyor belt crossing orography

2021

Warm conveyor belts (WCBs) are important airstreams in extratropical cyclones, often leading to the formation of intense precipitation and the amplification of upper-level ridges. This study presents a case study that involves aircraft, lidar and radar observations in a WCB ascending from western Europe towards the Baltic Sea during the Hydrological Cycle in the Mediterranean Experiment (HyMeX) and T-NAWDEX-Falcon in October 2012, a preparatory campaign for the THORPEX North Atlantic Waveguide and Downstream Impact Experiment (TNAWDEX). Trajectories were used to link different observations along the WCB, that is, to establish so-called Lagrangian matches between observations. To this aim, a…

Pore and mineral structure of rock using nano-tomographic imaging

2015

ABSTRACTIn order to better understand the micrometer-scale structure of rock and its transport properties which arise from it, seven monomineral samples from two sites (Olkiluoto and Sievi, Finland) were studied with micro- and nanotomography and scanning electron microscopy. From the veined gneiss of Olkiluoto we studied biotite, potassium feldspar, plagioclase (composition of oligoclase) and cordierite, and from Sievi tonalite biotite and two grains of plagioclase (albite). These minerals were the main minerals of these samples. Samples were carefully separated and selected using heavy liquid separation and stereomicroscopy, their three dimensional structure was imaged using X-ray tomogra…

"On-the-go" multispectral imaging system embedded on a track laying tractor to characterize the vine foliage

2015

Mutispectral imaging systems are widely used in remote sensing for Precision Viticulture. In this work, this technique was applied in the proximal sensing context to characterize vine foliage. A mobile terrestrial experimental system is presented, composed of a GPS receiver, a multi-spectral camera acquiring visible and near infrared images, and a Greenseeker RT-100 which measures the Normalized Difference Vegetative Index (NDVI). This optical system observes vine foliage in the trellis plan, in natural sunlight. The experimental field is planted with Chardonnay, Pinot Noir and Meunier cultivars in a latin squared pattern. In 2013, six datasets were acquired at various phenological stages.S…

Baltijas jūras attīstības stadiju krasta līnijas Ventspils lagūnas apkārtnē

2019

Kompleksā Baltijas jūras attīstība skārusi ne vienu vien piejūras teritoriju, piemēram, jūras transgresijas vai regresijas rezultātā radot lagūnas. Tāda ir arī senā Ventspils lagūna, kas piedzīvojusi gan vairākkārtīgus ūdens līmeņa celšanās jeb transgresijas periodus, radot akmens laikmeta cilvēkam pievilcīgus lagūnas apstākļus, gan arī regresijas periodu radītos sauszemes apstākļus, kādi senās lagūnas teritorijā ir arī mūsdienās. Izmantojot automatizētu LiDAR datu apstrādes metodi, iegūts augstas detalizācijas reljefa modelis, kas izmantots seno krasta līniju dešifrēšanā. Analizējot iegūtos seno krasta līniju datus, pēc lagūnas reljefa modeļa precizēšanas, veikta seno ūdens līmeņu modelēša…
