Energy efficient model for biogas production in farm scale

2011

Energy efficient solutions for six farm biogas production was found by calculating mass and energy balance in different scenarios. Raw materials in biogas production were cow manure and grass silage that were produced in these farms. There were calculated mass and energy balances on average for one year biogas prouduction that consisted of grass silage production, raw material transportation and biogas production in the biogas plant. In addition, direct greenhouse gases from biogas production were estimated. The direct mass and energy flows were calculated. It turned out that one input energy unit can produce 5.0 to 5.5 energy units as heat and electricity. Biogas reactor consumed heat from…

Potential for large-bodied zooplankton and dreissenids to alter the productivity and autotrophic structure of lakes

2014

While limnological studies have emphasized the importance of grazers on algal biomass and primary production in pelagic habitats, few studies have examined their potential role in altering total ecosystem primary production and it’s partitioning between pelagic and benthic habitats. We modified an existing ecosystem production model to include biotic feedbacks associated with two groups of large-bodied grazers of phytoplankton (large-bodied zooplankton and dreissenid mussels) and estimated their effects on total ecosystem production (TEP), and the partitioning of TEP between phytoplankton and periphyton (autotrophic structure) across large gradients in lake size and total phosphorus (TP) co…

Benthic mats offer a potential subsidy to pelagic consumers in tundra pond food webs

2014

We quantified the potential nutritional contribution of benthic mats to pelagic consumers in tundra ponds using three approaches. (1) We compared benthic and pelagic habitats based on their algal biomass and community composition and assessed the dietary quality in terms of fatty acid (FA) concentrations in both habitats. The algal community compositions differed significantly between habitats. Both benthic and pelagic habitats contained saturated and unsaturated FAs, but on average there were more FAs relative to carbon in the pelagic habitat (44 6 29 mg mg C21) than the benthic habitat (23 6 18 mg mg C21) across all studied ponds. (2) We quantified the contribution of benthic mats to the …

Regulation of type 1 fimbriae synthesis and biofilm formation by the transcriptional regulator LrhA of Escherichia coli

2005

Type 1 fimbriae ofEscherichia colifacilitate attachment to the host mucosa and promote biofilm formation on abiotic surfaces. The transcriptional regulator LrhA, which is known as a repressor of flagellar, motility and chemotaxis genes, regulates biofilm formation and expression of type 1 fimbriae. Whole-genome expression profiling revealed that inactivation oflrhAresults in an increased expression of structural components of type 1 fimbriae.In vitro, LrhA bound to the promoter regions of the twofimrecombinases (FimB and FimE) that catalyse the inversion of thefimApromoter, and to the invertible element itself. TranslationallacZfusions with these genes and quantification offimEtranscript le…

Alianzas antiembalse y luchas hidroepistemológicas. Los retos de la gestión colectiva del agua en el Río Grande, Málaga, España

2018

En este artículo analizamos las luchas epistemológicas y retos que ha tenido el movimiento social en la subcuenca del río Grande frente a los diversos proyectos modernizadores que intentan transferir el agua rural hacia la ciudad de Málaga. El primero asociado a la construcción de un gran embalse y el segundo con la modernización de los sistemas de riego tradicionales. Concluimos que el reto está en desenmascarar el régimen de verdad que respalda los proyectos de modernidad hidráulica, reivindicar los derechos de uso y control colectivos del agua y así generar procesos de apropiación comunitaria para la defensa del río como un bien socio-ambiental, económico-cultural y político-epistemológi…

Samhandling om tjenester til personer med utviklingshemming og samtidig psykiske lidelser/ plager: Hvilke erfaringer har deres foreldre?

2016

Masteroppgave psykisk helsearbeid - Universitetet i Agder 2016 National as well as international research shows that people with mental retardation are more prone to develop mental ailments and behavioral problems then the general population. Still, little subject material illuminates the collaboration of services provided to this group of people. The purpose of this study is to explore how the parents of people with mental retardation and simultaneous mental illnesses/ ailments perceive the collaboration of services provided to their offspring: What are their experiences on collaboration between the different service providers? How do they view collaboration between themselves/ their offsp…

Modelling the effect of ethanol on growth rate of food spoilage moulds

2005

The effect of ethanol (E) on the radial growth rate (mu) of food spoilage moulds (Aspergillus candidus, Aspergillus flavus, Aspergillus niger, Cladosporium cladosporioides, Eurotium herbariorum, Mucor circinelloides, Mucor racemosus, Paecilomyces variotii, Penicillium chrysogenum, Penicillium digitatum, Rhizopus oryzae and Trichoderma harzianum) was assessed in Potato Dextrose Agar (PDA) medium at a(w) 0.99, 25 degrees C. In order to model this effect, the Monod type equation described previously by Houtsma et al. (Houtsma, P.C., Kusters, B.J.M., de Wit, J.C., Rombouts, F.M., Zwietering, M.H., 1994.

Assembled policies : the Finnish case of restricted entitlement to early childhood education and care

2019

In this article, we utilize an application of Deleuze and Quattari’s (1987) concept of assemblage to explore and better understand the interconnectedness and materiality of the policies of early childhood education and care (ECEC). To exemplify how directing our focus to assemblages can further the understanding of policies in the everyday life of families, we will present a Finnish case of entitlement to ECEC. Since 1996, children under school age have enjoyed the entitlement to full-day ECEC provided by local authorities. In 2016, the Finnish parliament enforced new legislation that allows municipalities to limit this entitlement to 20 hours per week unless the child’s parents work or stu…

Understanding and measuring social entrepreneurship

2017

This thesis aims to understand the phenomenon of social entrepreneurship and measure its component dimensions. In particular, the thesis addresses two research gaps in the social entrepreneurship research. The first gap addressed is the resource mobilization during marketing strategy development of a social enterprise in its start-up stage. Social entrepreneurship is a diverse concept constituting various organizational form and activities. Hence, the second research gap that this research study addresses is the issue of measurement of social entrepreneurship construct. The thesis consists of an introductory essay and five research articles. The first two articles in this compilation addres…
