Preventive Conservation: a Key Method to Ensure Cultural Heritage’s Authenticity and Integrity in Preservation Process

2012

This article studies the role of preventive conservation in cultural heritage preservation. It shows through cultural heritage theory and conservation professions development process how important part preventive conservation has had and still has in cultural heritage preservation and damage prevention. Preventive conservation is a multidisciplinary orientation that uses indirect measures and actions to avoid or to minimize future deterioration or loss of cultural heritage. Conservation professionals should recognize its importance as the most effective method in promoting the long-term preservation of cultural heritage. Therefore, preventive conservation should be the basic theoretical per…

SciPy 1.0 : fundamental algorithms for scientific computing in Python

2020

SciPy is an open-source scientific computing library for the Python programming language. Since its initial release in 2001, SciPy has become a de facto standard for leveraging scientific algorithms in Python, with over 600 unique code contributors, thousands of dependent packages, over 100,000 dependent repositories and millions of downloads per year. In this work, we provide an overview of the capabilities and development practices of SciPy 1.0 and highlight some recent technical developments. peerReviewed

Offsetting harmful ecological impacts by restoring conservation areas

2019

Ihmistoiminnasta aiheutuvat ekologisesti haitalliset vaikutukset voidaan kompensoida tuottamalla luonnon kannalta hyötyjä, esimerkiksi ennallistamalla elinympäristöjä tai perustamalla uusia luonnonsuojelualueita. Elinympäristön ennallistaminen mahdollistaa elinympäristön palautumisen kohti luonnontilaa. Tämän tutkimuksen tarkoituksena oli selvittää, voitaisiinko jo aiemmin suojelluilla alueilla tehtävällä ennallistamisella saavuttaa ekologisessa kompensaatiossa tarvittava luontohyöty. Voi ehkä vaikuttaa siltä, että tällä tavoin tuotetut hyödyt eivät ole luonnon kannalta lisäisiä, koska toimenpiteet kohdistuvat alueisiin, jotka ovat jo suojeltu. Suomessa on kuitenkin tällä hetkellä monia suo…

<strong>First record of the plant bug genus <em>Euchilofulvius</em> from Myanmar (Hemiptera: Heteroptera: Miridae: Cylapinae), with…

2015

The cylapine plant bug genus Euchilofulvius was proposed by Poppius (1909) to accommodate a single Indonesian species, E. tibialis Poppius from Mentawai Islands. Several subsequent works have fragmentally added six valid species (Gorczyca, 2006, 2008; Poppius, 1913; Schuh, 1995, 2002–2014 online catalog; Yasunaga & Miyamoto, 2006; Yasunaga et al., 2012), and currently, the following seven members are known mainly from the Oriental Region: E. antennatus Gorczyca, 1999 (Sulawesi); E. carinatus (Poppius, 1913) (India, Sri Lanka); E. josifovi Gorczyca, 2008 (Malaya); E. lepidopterus Yasunaga & Miyamoto, 2012 (Okinawa, Japan); E. pallescens Gorczyca, 2002 (Solomon Islands); E. tibialis Poppius, …

Sex ratio and spatial distribution of male and female Antennaria dioica (Asteraceae) plants

2011

Sex ratio, sex spatial distribution and sexual dimorphism in reproduction and arbuscular mycorrhizal colonisation were investigated in the dioecious clonal plant Antennaria dioica (Asteraceae). Plants were monitored for five consecutive years in six study plots in Oulanka, northern Finland. Sex ratio, spatial distribution of sexes, flowering frequency, number of floral shoots and the number and weight of inflorescences were recorded. In addition, intensity of mycorrhizal fungi in the roots was assessed. Both sexes flowered each year with a similar frequency, but the overall genet sex ratio was strongly female-biased. The bivariate Ripley’s analysis of the sex distribution showed that within…

The marine diapsid reptile Endennasaurus from the Upper Triassic of Italy

2005

The marine reptile Endennasaurus from the Upper Triassic Zorzino Limestone of northern Italy is rede- scribed and reassessed. New details of the skull and postcra- nial skeleton are revealed, confirming the attribution of this genus to the diapsid reptile clade Thalattosauriformes. Phylo- genetic analysis suggests that Endennasaurus was related to the European genus Askeptosaurus and the Chinese Anshun- saurus. Despite a rather conservative postcranial morphology, Endennasaurus clearly occupied a highly specialized dietary niche as it combined a slender tapering premaxillary rostrum with a complete absence of either marginal or palatal teeth.

Fast Green’s Function Method for Ultrafast Electron-Boson Dynamics

2020

The interaction of electrons with quantized phonons and photons underlies the ultrafast dynamics of systems ranging from molecules to solids, and it gives rise to a plethora of physical phenomena experimentally accessible using time-resolved techniques. Green's function methods offer an invaluable interpretation tool since scattering mechanisms of growing complexity can be selectively incorporated in the theory. Currently, however, real-time Green's function simulations are either prohibitively expensive due to the cubic scaling with the propagation time or do neglect the feedback of electrons on the bosons, thus violating energy conservation. We put forward a computationally efficient Gree…

Conductive and Capacitive Properties of the Bipolar Membrane Junction Studied by AC Impedance Spectroscopy

2001

The complete ac impedance spectrum of four bipolar membranes is analyzed both theoretically and experimentally taking into account both ionic transport and water dissociation together with the structural aspects of the bipolar junction. A theoretical model based on the Nernst-Planck and Poisson equations for the conductive and capacitive properties of the junction provides a qualitative description of the bipolar membranes for a broad range of electric currents and temperatures. Special attention is paid to the characteristics of the bipolar junction structure and the contact region between the two ion-exchange layers. It is observed that the effective area of this region increases with the…
