On a solid agar medium the growth-inhibitory effect of 9 Lactobacillus strains cultured from vaginal content was tested on bacteria cultured from vaginal content of women with bacterial vaginosis: Mobiluncus, Gardnerella vaginalis, Bacteroides and anaerobic cocci. Inhibition zones were observed in the growth of all of the strains isolated from women with bacterial vaginosis around all lactobacilli

Twenty-four strains of Mobiluncus mulieris and 27 strains of Mobiluncus curtisii were tested with respect to 6 different biochemical characteristics: arginin-decarboxylase activity, beta-galactosidase activity, synergistic hemolysis with Staphylococcus aureus, hydrolysis of hippurate, migration through soft agar and reduction of nitrate. Antigens of the same strains, prepared by ultrasonication, w

Twenty strains of anaerobic curved rods isolated from vaginal secretion were studied with light and transmission electron microscopy. Ten of the strains were of a short (approx. 1.5 microns) Gram-variable type, while ten were of a long (approx. 3 microns) Gram-negative type. The former had one to four flagella and the latter between one and eight. The flagella originated from the concave aspect of

Biogenic volatile organic compound (BVOC) flux dynamics during the subarctic autumn are largely unexplored and have been considered insignificant due to the relatively low biological activity expected during autumn. Here, we exposed subarctic heath ecosystems to predicted future autumn climate scenarios (ambient, warming, and colder, dark conditions), changes in light availability, and flooding, t

Measured aerosol size distributions from three measurement stations and modeled air mass trajectory data were combined to study aerosol dynamics in the boreal forest zone in Northern Scandinavia. Three approaches were used: investigation of new particle formation events, analysis of air masses arriving from ocean to continent, and study of changes in the aerosol size distributions when air masses

In this study, we present summertime concentrations and fluxes of biogenic volatile organic compounds (BVOCs) measured at a sub-arctic wetland in northern Sweden using a disjunct eddy-covariance (DEC) technique based on a proton transfer reaction mass spectrometer (PTR-MS). The vegetation at the site was dominated by Sphagnum, Carex and Eriophorum spp. The performance of the DEC system was assesse

The health limit values for PM10 concentration which are presently in force cannot be met on many heavily polluted streets in German conurbations. Soot filters, bans on motorised traffic during certain time periods and areas or for specific vehicle classes, speed limits and other measures are meant to lead to a substantial reduction of the pollution. This article compares the effects of the mentio

The thermal comfort conditions were analyzed for people within a street canyon, a medium sized city in the southern upper Rhine plain, during the summer heatwave 2003. Continuous measurements of all meteorological data necessary to calculate PET that is air temperature Ta, vapor pressure VP, wind speed v, and short and long wave radiation flux densities from the three-dimensional (3D) surroundings

Meteorological investigations were carried out in forests in the southwestern part of the Swabian Alb (SW Germany) to analyze the influences of exposition and silvicultural treatment on the microchmate within various stands of beech (Fagus sylvatica L.). The measurements were taken as part of an interdisciplinary project on the effects of climate and forest management on structures and processes w

Accurate maps of past land cover and human land use are necessary for studying the impact of anthropogenic land-cover changes, such as deforestation, on the climate. The maps of past land cover should ideally be separated into naturally occurring vegetation and human-induced changes, thereby enabling the quantification of the effect of human land use on the past climate. We developed a Bayesian hi

Safety routines such as the WHO surgical safety checklist and SBAR have gained widespread attention and implementation in healthcare. However, there has also been criticism. With the ongoing Covid-19 pandemic, the need for knowledge about how safety routines work in practice is larger than ever. In light of these obstacles, I suggest two approaches to the study of healthcare safety routines, based

Objectives: Gram-positive anaerobic cocci (GPAC) are often regarded as harmless commensals associated with skin and mucosal surfaces. Investigations regarding these bacterial species often concern clinical case reports. In immunocompromised individuals, in the presence of comorbidities, such as diabetes or due to breach of skin barriers, the GPAC can cause infections. Nonetheless, information on t

The upcycling trend has received renewed attention in the past few years due to growing concerns for the environment related to increased resource consumption and waste volumes. Indeed, cities across the world are supporting resource upcycling initiatives by establishing do-it-yourself (DIY) repair cafes and makerspaces as a means to transform societies towards sustainable develop-ment. However, t
