Objectives: Optimal surgical management for patients with transposition of the great arteries (TGA), ventricular septal defect (VSD) and left ventricular outflow obstruction (LVOTO) remains controversial. Although the Rastelli operation has been the most widely performed surgical procedure during the past decades, several studies have shown its suboptimal long-term prognosis. Other operations have been developed to improve results. This study was performed to compare the outcomes of the different surgical ...

Small and medium-sized tourism enterprises (SMTEs) face the challenges of renewing business models to maintain competitiveness in the global economy. SMTE networking and product innovations are typical responses to these challenges. SMTE innovation processes and networking dynamics were analysed in the Saimaa Holiday network in the Savonlinna region of Finland. The Finnish Nationally Networked Centre of Expertise for Tourism (CET) networking model was used for the analysis. It was confirmed that innovation ...

Current office buildings are becoming more and more energy efficient. In particular the importance of heating is decreasing, but the share of electricity use is increasing. When the CO2 equivalent emissions are considered, the CO2 emissions from embodied energy make up an important share of the total, indicating that the building materials have a high importance which is often ignored when only the energy efficiency of running the building is considered. This paper studies a new office building ...

Abstract The nutrient load of the River Neva and the St. Petersburg region strongly affects the trophic status of the eastern Gulf of Finland. The extent of eutrophication and its effect on the phytoplankton community were studied in the eastern Gulf of Finland in August 1990–1992. The phytoplankton of the easternmost part was dominated by an assemblage of fresh-water and brackish-water species, including numerous indicators of eutrophication. Inside the St. Petersburg flood-protection barrier, ...

We present a multimodal media center interface designed for blind and partially sighted people. It features a zooming focus-plus-context graphical user interface coupled with speech output and haptic feedback. A multimodal combination of gestures, key input, and speech input is utilized to interact with the interface. The interface has been developed and evaluated in close cooperation with representatives from the target user groups. We discuss the results from longitudinal evaluations that took ...

Missionary work was one of the main forces in the opening of the African continent to direct western influence. In many cases, from the 1830s onwards, missionaries were the first Westerners residing in the interior of the continent, thus accumulating considerable knowledge concerning geographical conditions in their respective areas of residence. The question arises: how did information from these people with scarce knowledge about the interior filter down to representations of geographical conditions ...

Collecting and utilizing product life-cycle data is both difficult and expensive for products that move between different industrial settings at various points of the product life-cycle. Product-centric approaches that present effective solutions in tightly integrated environments have been problematic to deploy across multiple industries and over longer timespans. Addressing deployment costs, incentives, and governance, this paper explores a blockchain-based approach for the deployment of product- ...

This article applies recently developed panel estimation techniques to estimate the elasticity of private production with respect to public capital in a regional framework. We use the widely applied production function approach and regional data from Finland for the 1975–2004 period. In contrast to many previous studies about the productivity of public capital, we focus especially on panel estimation techniques, showing that the results from commonly applied fixed effects OLS are probably biased ...

Traditionally, the Finnish legislation have focused on energy use and especially on energy used for heating space in buildings. However, in many cases this does not lead to the optimal concept in respect to minimizing green house gases. This paper studies how CO2 emission levels are affected by different measures to reduce energy use in buildings. This paper presents two real apartment buildings with different options of energy efficiency and power sources. The calculations clearly show that in ...

Purpose To analyse productivity of public expenditures; especially to find out the effect of human capital investment on private sector productivity. Design/methodology/approach Several measures of public sector capital stock are constructed. These measures are used in testing the effects on private sector productivity. Empirical analysis makes use of cross‐country panel data and utilizes various panel econometric methods. Findings The main finding is that public sector capital has a positive impact ...

Cattle feeding in Northern Europe is based on grass silage, but grass growth is highly dependent on weather conditions. If ensuring sufficient silage availability in every situation is prioritised, the lowest expected yield level determines the cultivated area in farmers' decision-making. One way to manage the variation in grass yield is to increase grass production and silage storage capacity so that they exceed the annual consumption at the farm. The cost of risk management in the current and ...

The development of hydrographical cartography in the Baltic Sea in the eighteenth century provides a challenging case for contextualizing cartographic history. A framework is set up here for the interpretation of complex interrelationships between maps and society. This framework emphasizes spatial material practices and territoriality from a geopolitical perspective. Seen from the point of view of material practices, specifically, that is, expanding international maritime trade and changes in military ...
