The historical regions of Europe: civilizational backgrounds and multiple routes to modernity [PDF]

open access: yes, 2012
A systematic typology or comparative analysis of European historical regions does not exist and there is relatively little literature on the topic. The argument in this paper is that a six-fold classification is needed to capture the diversity of Europe ...

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

FOREIGN DIRECT INVESTEMENTS FLOWS IN BLACK SEA ECONOMIC COOPERATION [PDF]

open access: yes, 2011
We live in a time when the world’s economy is in a constantly change. Foreign direct investments flows are in actual economy one of the most dynamic and prospective part of the world’s economy being in a continuous globalization.

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

open access: yesDeep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Hydrologic homogeneous regions using monthly Streamflow in Turkey [PDF]

open access: yes, 2008
Cluster analysis of gauged streamflow records into homogeneous and robust regions is an important tool for the characterization of hydrologic systems.

Trends in marine species distribution models: a review of methodological advances and future challenges

open access: yesEcography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Suitability of anthrax (Bacillus anthracis) in the Black Sea basin through the scope of distribution modelling.

open access: yesPLoS ONE
The Black Sea basin has a strategic geographic location bridging Asia and Europe and depends on traditional livestock practices for their local economies.

Interwar Views on ManagingEastern European Space: Exploring Lypa’s Conceptualisation of theBlack Sea States Union [PDF]

open access: yesCentral European Journal of International & Security Studies, 2014
Few people realise that the idea of establishing a Black Sea Union (BSU) – a regional bloc along the Black Sea littoral – was proposed in the immediate aftermath of WWII.

Habitat complexity and prey composition shape an apex predator's habitat use across contrasting landscapes

open access: yesEcography, EarlyView.
The spatial ecology of stalk‐and‐ambush predators like the Eurasian lynx Lynx lynx depends on prey availability and environmental features, yet the relative roles of these factors remain unclear at large spatial scales. In this study, we analysed lynx habitat use across central and southern Finland using snow‐track data from the Wildlife Triangle ...
