Digital solutions transform the forest-based bioeconomy into a digital platform industry : a suggestion for a disruptive business model in the digita…

2018

With the notion that the transformation of the forest-based bioeconomy in recent years provides insightful suggestions not only on the bioeconomy, but on business innovation, this paper conducts an empirical analysis of the transformation and attempts to extract suggestions for a digital-solution-driven, disruptive business model in the digital economy. Notwithstanding the potential broad cross-sectoral benefits, the natural environment, locality constraints, and incessant challenge of distance have impeded the balanced development of the bioeconomy. However, driven by digital solutions, the bioeconomy has taken big steps forward in recent years. Digitalization has enabled real-time, end-to…

Real-time optimization of the key filtration parameters in an AnMBR: Urban wastewater mono-digestion vs. co-digestion with domestic food waste

2018

[EN] This study describes a model-based method for real-time optimization of the key filtration parameters in a submerged anaerobic membrane bioreactor (AnMBR) treating urban wastewater (UWW) and UWW mixed with domestic food waste (FW). The method consists of an initial screening to find out adequate filtration conditions and a real-time optimizer applied to a periodically calibrated filtration model for minimizing the operating costs. The initial screening consists of two statistical analyses: (1) Morris screening method to identify the key filtration parameters; (2) Monte Carlo method to establish suitable initial control inputs values. The operating filtration cost after implementing the…

Influence of Cognettia sphagnetorum (Enchytraeidae) on birch growth and microbial activity, composition and biomass in soil with or without wood ash

2001

In this laboratory study using microcosms with seedlings of silver birch (Betula pendula), we explored whether Cognettia sphagnetorum (Enchytraeidae) can retain its important role of accelerating decomposition processes in soils and stimulating primary production under disturbance. We established systems with or without wood ash amendment (first-order disturbance) in the soil, either in the presence or absence of C. sphagnetorum. To test whether the systems treated with wood ash are more sensitive to an additional disturbance than the ash-free systems, the microcosms were later on disturbed by drought. To determine the influence of two disturbances on the enchytraeids and populations of oth…

Success factors of game industry crowdfunding campaigns

2017

Tutkimuksen tarkoituksena oli selvittää mitkä ovat pelialan joukkorahoituskampanjoiden menestystekijöitä. Aiempaan joukkorahoitukseen sekä pelialaan keskittyneiden tutkimusten perusteella luotiin teoreettinen malli kuvaamaan tärkeimpiä menestystekijöitä ja niiden suhteita. Tätä mallia testattiin haastattelemalla kolmen eri joukkorahoituskampanjan perustajia. Aiemman teorian sekä haastattelujen perusteella selvisi, että pelialan joukkorahoituskampanjoilla on kuusi selkeää menestystekijää: kampanjan palkkiot, kampanjan tavoitteet, kampanjan sekä tuotteen laatu, projektitiimi, joukkorahoittajien luoma yhteisö sekä suoritetut esivalmistelut. Tutkimustuloksia ja niiden perus…

The quality of life in the Finnish game industry

2013

Tässä tutkimuksessa tutkitaan työntekijöiden elämänlaatua Suomen peliteollisuudessa. Tutkimus perustuu International Game Developers Associationin (IGDA) vastaavanlaiseen tutkimukseen, joka toteutettiin huhtikuussa 2004. Tavoitteena on tarkastella ongelmia, jotka ovat nähtävissä peliyritysten työympäristössä. Päätavoitteena tässä laadullisessa tapaustutkimuksessa oli selvittää, mitkä ovat yleisiä elämänlaatuun liittyviä ongelmia pelinkehitysyrityksissä ja mitkä olisivat parhaat käytännöt ehkäisemään tai vähentämään elämänlaatuun liittyviä ongelmia. Tutkimuksen tulokset osoittavat, että suomalaisella pelialalla on tällä hetkellä pula osaavista työntekijöistä. Vaikka peliteollisuus on nopeast…

Oligonucleotides-decorated-poly(N-vinyl pyrrolidone) nanogels for gene delivery

2013

Pulsed electron-beam irradiation of a semi-dilute poly(N-vinyl pyrrolidone) (PVP) aqueous solution in the presence of acrylic acid has led to a carboxyl functionalized nanogel system. Nanoparticles hydrodynamic size and surface charge density, in water and as a function of pH, were investigated by dynamic light scattering and laser doppler velocimetry, respectively. Nanogels (NGs) were proved not to be cytotoxic at the cellular level. Indeed, they rapidly bypass the cellular membrane to accumulate in specific cell portions of the cytoplasm, in the perinuclear area. The availability of pendant carboxyl groups on the crosslinked PVP NGs core prompted us to attempt their decoration with a sing…

The adsorption of water vapor on super absorbent product at low temperatures and low mass.

2006

The adsorption isotherms of water vapor on super absorbent product have the same form of type III isotherm at ambient temperature with the hysteresis phenomena. For temperatures lower than ambient, the isotherms become deformed because of the chains effect. The polymer is characterized by a multilayer adsorption, which occurs before a full-course is complete. During adsorption reactions, the polymer undergoes rearrangement polymeric network, which results from a cooperative diffusion of the water molecules and from a chain spacing followed by an expansion of the polymeric network. Three types of water molecules adsorbed on polymer were identified: strongly dependent water, adsorbed water, a…

CO2-Based Non-ionic Surfactants: Solvent-Free Synthesis of Poly(ethylene glycol)-block-Poly(propylene carbonate) Block Copolymers

2013

Copolymerization of carbon dioxide (CO2) and propylene oxide (PO) is employed to generate amphiphilic polycarbonate block copolymers with a hydrophilic poly(ethylene glycol) (PEG) block and a nonpolar poly(propylene carbonate) (PPC) block. A series of poly(propylene carbonate) (PPC) di- and triblock copolymers, PPC-b-PEG and PPC-b-PEG-b-PPC, respectively, with narrow molecular weight distributions (PDIs in the range of 1.05–1.12) and tailored molecular weights (1500–4500 g mol−1) is synthesized via an alternating CO2/propylene oxide copolymerization, using PEG or mPEG as an initiator. Critical micelle concentrations (CMCs) are determined, ranging from 3 to 30 mg L−1. Non-ionic poly(propylen…

Learning and remembering the environment in the blind cave fishAnoptichthys jordani

1989

1. The swimming behavior of blind cave fish (Anoptichthys jordani) differs in familiar and unfamiliar surroundings. Following release in unfamiliar surroundings, or after alterations of a familiar environment, the fish increase swimming velocity in order to optimize lateral line organ stimulation. Furthermore, they glide along boundary features more often than they do in familiar surroundings. These characteristics of swimming behavior were used to measure the occurrence and duration of exploratory behavior. 2. Fish removed from a familiar environment for as long as 2 days spend less time exploring when returned than when they were initially placed in the environment. After a longer absence…
