Materiały do znajomości ryjkowców (Coleoptera: Curculionoidea) Beskidu Wschodniego
2017
The paper presents new data on the distribution of the superfamily Curculionoidea in the Eastern Beskidy Mountains. The study was carried out between 2003 and 2015 in the south-western part of this region. A list of 134 species of Curculionoidea classified into 7 families (Anthribidae, Attelabidae, Rhynchitidae, Nanophyidae, Apionidae, Curculionidae, Erirhinidae) is presented. Some of them are rare in Poland or have been collected in this region for the first time: Chonostropheus tristis, Aspidapion validum, Barynotus moerens, Dodecastichus inflatus, Otiorhynchus obsidianus, Lixus punctiventris, Tachyerges rufitarsis and Lignyodes suturatus.
The orophilous communities of the Pino-Juniperetea class in the Central and Eastern Mediterranean area
2001
Orophilous plant communities of the Pino-Juniperetea class, occurring in the Central and Eastern Mediterranean area, are examined. This vegetation is characterized by the dominance of trees and shrubs, mostly represented by conifers belonging to the genera Juniperus, Abies and Pinus. These communities are nowadays relegated to the supra- and oromediterranean belt, and show a fragmentary distribution, which is an evident proof of their relict connotation. The comparison among these communities, based on original and literature data, has highlighted a remarkable floristic and structural homogeneity, together with a series of geographical vicariances. From the phytosociological point of view, …
LIFE CARE ANNUITIES (LCA) EMBEDDED IN A NOTIONAL DEFINED CONTRIBUTION (NDC) FRAMEWORK
2016
AbstractThis paper examines the possibility of embedding public long-term care (LTC) insurance within the retirement pension system, i.e. introducing life care annuities into a notional defined contribution framework. To do this, we develop a multistate overlapping generations model that includes the so-called survivor dividend and give special attention to the assumptions made about mortality rates for dependent persons and LTC incidence rates, which largely determine the contribution rate assigned to LTC. The proposed model could be of interest to policymakers because it could be implemented without too much difficulty, it would universalize LTC coverage with a “fixed” cost, and it would …
Subjective Economic Risk to Beneficiaries in Notional Defined Contribution Accounts
2006
ABSTRACT This article aims to quantify the aggregate subjective economic risk to which beneficiaries would be exposed if a retirement pension system based on notional account philosophy were introduced. We use scenario generation techniques to make projections of the factors that determine the real expected internal rate of return (IRR) and the expected replacement rate (RR) for the beneficiary according to six retirement formulae based on the most widely accepted rates or indices. We then apply the model to the case of Spain. Our projections are based on Herce and Alonso's macroeconomic scenario 2000-2050 (2000) and include information about the past performance of the indices and the time…
Automatic Balance Mechanisms in Pay-As-You-Go Pension Systems
2009
This paper shows the usefulness of the automatic balance mechanisms (ABMs) and explores the issue of introducing an ABM into the Spanish public contributory retirement pension system. We define the concept of the automatic balance mechanism and carry out an analysis of those existing in Sweden, Canada, Germany, Japan and Finland. We also present an indicator of the Spanish system's solvency which emerges from the actuarial balance sheet, and simulate the effect that certain changes in the parameters of the present system would have on solvency, showing the direction that could be taken if the mechanism were to be introduced in Spain. The main conclusion reached is that, given the system's s…
The role of community-based knowledge and local institutions in managing landslides on the slopes of Mount Elgon, Uganda
2015
The paper explores the degree to which community-based knowledge (CBK) and local institutions can be effective for disaster preparedness and management, based on a study carried out in Nametsi Parish, located on the slopes of Mount Elgon, in eastern Uganda. The study area has experienced innumerable landslides since 1933. Whereas a few of the landslides have not been disastrous, several others have had far-reaching effects on the livelihoods of people living in the area. This is attributed partly to the geographical setting, which makes the area difficult to access, and partly to socio-economic factors such as a high population growth rate and widespread poverty. Despite these aspects of vu…
Comparison on the use of PV systems in the vertical walls
2015
In this article the preliminary evaluation of the performance of a photovoltaic window is presented. The aim is to trace the behavior of next-generation systems, which favor architectonical integration. Three different systems have been taken into account: a dye sensitized solar cell (DSSC), blue and grey caved silicon panels. The systems can be placed behind a window or behind a wall of glass blocks.
Modeling of Wind Turbine Gearbox Mounting
2011
In this paper three bushing models are evaluated to find a best practice in modeling the mounting of wind turbine gearboxes. Parameter identification on measurements has been used to determine the bushing parameters for dynamic simulation of a gearbox including main shaft. The stiffness of the main components of the gearbox has been calculated. The torsional stiffness of the main shaft, gearbox and the mounting of the gearbox are of same order of magnitude, and eigenfrequency analysis clearly reveals that the stiffness of the gearbox mounting is of importance when modeling full wind turbine drivetrains.
On-grid residential development with photovoltaic systems in Southern Norway
2013
The application of residential photovoltaic (PV) systems is increasing rapidly worldwide. In Southern Norway, a group of on-grid smart houses with embedded PV systems, solar thermal collectors, and geothermal heat pumps are under development at Skarpnes. In this paper, performance analysis based on simulations of an on-grid residential house with PV system located at Skarpnes is presented. This project is expected to demonstrate zero energy and zero emission housing in Norway. This paper discusses a theoretical study of home energy consumption with electricity production for a single house from a PV system, including simulations of irradiation conditions and tilt angles, and of the PV syste…
Multimodal user interface for a semi-robotic visual assistance system for image guided neurosurgery
2005
Abstract We developed a visual assistance system for image guided neurosurgery, consisting of a stereoscopic digital camera (exoscope) mounted on a semi-robotic manipulator. In order to minimize the operation time, the application-specific multimodal user interface enables hands-free manipulation of the exoscope. The surgeon wears thereby a head-mounted unit with a binocular display, a head tracker, a microphone and earphones. Different modes of view positioning and adjustment can be selected by voice and controlled by head rotation while pressing a miniature confirmation button mounted on a finger ring or suction device. Apart from the development of the mechatronic and software modules of…
