Kiven lumo

Aikuiskasvatus, 2006
Kansalais- ja työväenopistot – määrältään noin 250 opistoa – täyttyivät jälleen tänä syksynä innokkaista aikuisopiskelijoista. Vuosittain kansalais- ja työväenopistoissa opiskelee liki 800 000 suomalaista. Kysytyimpiä ovat vieraat kielet, kättentaidot ja liikunta. Tässä kuvattu geologinen kivikurssi on vapaan sivistystyön piirissä erikoiskurssi.

Sosiaalipolitiikan lumo

, 2016
Sosiaalipolitiikan Lumon kirjoittajilla on viesti. Mielestämme politiikan keskeiseksi tavoitteeksi tulisi asettaa sosiaalinen ja ekologinen hyvinvointi. Tätä tavoitetta kohti tulisi kulkea universalismin periaattein ja kansalaisten perusturva, oli sitten kyse työllisistä tai työttömistä, nuorista tai iäkkäistä, kantaväestöstä tai maahanmuuttajista ...

3-D Multi-Component Reverse Time Migration Method for Tunnel Seismic Data

Sensors, 2021
Migration imaging is a key step in tunnel seismic data processing. Due to the limitation of tunnel space, tunnel seismic data are small-quantity, multi-component, and have a small offset.

Single Excitation Energies Obtained from the Ensemble "HOMO-LUMO Gap": Exact Results and Approximations.

Journal of Physical Chemistry Letters, 2022
In calculations based on density functional theory, the "HOMO-LUMO gap" (difference between the highest occupied and lowest unoccupied molecular orbital energies) is often used as a low-cost, ad hoc approximation for the lowest excitation energy. Here we

A QUANTUM CHEMICAL STUDY OF SMALL MOLECULES USED AS ACTIVE LAYER COMPONENT OF ORGANIC SOLAR CELLS

Momento, 2020
Organic solar cells (OSCs) are one of the best alternatives in the photovoltaic area. These devices convert directly sunlight into electrical current with reasonable efficiencies. The most important component of an OSC is the photoconductive active layer
