Changes in Spatial and Sectoral Patterns of Employment in Ile-de-France, 1978-97
2006
This paper investigates the spatial distribution of employment in the region of Ile-de-France in 1978 and 1997. Exploratory spatial data analysis is used to identify employment centres and a sectoral analysis of the central business district (CBD) and sub-centres is performed. The results highlight a process of suburbanisation of employment in Ile-de-France between 1978 and 1997. A more polarised space emerges in 1997 than in 1978, with several employment centres specialised in different activities. Moreover, even if the spatial influence of the CBD declines over the study period, the CBD maintains its economic leadership by concentrating a large variety of high-order producer services.
Delineation of the boundary of an urban agglomeration: evidence from Riga, Latvia
2019
AbstractStatistical, morphological and functional approaches have long been used to delineate spatial boundaries of urban agglomerations. This research uses data from the Central Statistical Bureau and the State Revenue Service. The results indicate that morphological and functional approaches are essential when defining the agglomeration, however the outcomes are different. The most relevant consistency was observed in the territorial units adjoining the city of Riga due to the fact that they have a common labour market with Riga and share a strong functional linkage. However, the spatial extent based on the morphological approach confirms and highlights the effects of urban sprawl.
Suburban Fertility and Metropolitan Cycles: Insights from European Cities
2021
Being largely diversified along the urban–rural gradient, fertility gaps have demonstrated to fuel metropolitan expansion, contributing to natural population growth and social change. In this direction, population dynamics and economic transformations have continuously shaped urban cycles in Europe. Assuming suburban fertility to be a relevant engine of metropolitan growth, the present study investigates and discusses the intrinsic relationship between fertility transitions and urban expansion, focusing on European metropolitan regions. An average crude birth rate referring to the last decade (2013–2018) was estimated from official statistics at 671 Functional Urban Areas (FUAs, Eurostat Ur…
General Consideration of the Agricultural Holding in Arges County
2013
Abstract This paper aims to present the state farms and agricultural area used by those in the county of Arges and Sud-Muntenia region according to legal personality, based on the latest statistics. In this paper we address the size of agricultural holdings in terms of physical size, agricultural area (UAA) in number of hectares, by type of animal that you own and the number of farms.In the analyzed period shows that the agricultural sector in Romania individual continues to be the main component of Romanian private farming, which consists of individual farms and family associations without legal personality disorder. The data indicates that we are dealing with a decrease in average 5% from…
Propozycja regionalizacji fizycznogeograficznej Sudetów Wschodnich
2018
Artykuł przedstawia propozycję wyznaczenia granic Sudetów Wschodnich oraz podziału fizycznogeograficznego makroregionu na mezoregiony. Przy wyznaczaniu granic uwzględniono w większym stopniu genetyczno-geologiczny podział Sudetów związany z orogenezą waryscyjską. W podziale na mezoregiony w większym stopniu uwzględniono kryteria litostratygraficzne.
APPLICATION OF UNMANNED AERIAL VEHICLES FOR GLACIER RESEARCH IN THE ARCTIC AND ANTARCTIC
2019
Unmanned aerial vehicles or drones are nowadays widely used in a broad field of scientific and commercial applications. Despite this, it is quite a new method for glacier mapping in polar regions and has a lot of advantages, as well as disadvantages over more classical remote sensing instruments. Here we examine the main issues associated with the application of drones for glacier research from our experience in Iceland, Greenland and the Antarctic. We use DJI Phantom series drones for the obtaining of aerial photographs and produce digital surface models (resolution of 8 – 16 cm) and orthomosaics (resolution of 2 – 4 cm) for glacier mapping. Several issues related to the ground control poi…
A fast multi-dimensional magnetohydrodynamic formulation of the transition region adaptive conduction (TRAC) method
2021
We have demonstrated that the Transition Region Adaptive Conduction (TRAC) method permits fast and accurate numerical solutions of the field-aligned hydrodynamic equations, successfully removing the influence of numerical resolution on the coronal density response to impulsive heating. This is achieved by adjusting the parallel thermal conductivity, radiative loss, and heating rates to broaden the transition region (TR), below a global cutoff temperature, so that the steep gradients are spatially resolved even when using coarse numerical grids. Implementing the original 1D formulation of TRAC in multi-dimensional magnetohydrodynamic (MHD) models would require tracing a large number of magne…
Gestión de las sequías en la planificación hidrológica. Aplicación al sureste español
2020
La sequía es un riesgo climático con grandes repercusiones sobre los sistemas de abastecimiento para usos urbano-turísticos y agrícolas. Los objetivos de este trabajo son: 1) llevar a cabo una revisión y diagnóstico de las medidas llevadas a cabo en el sureste de España (cuenca hidrográfica del Segura) desde la planificación y la gestión del agua para usos urbanos; y 2) valorar su grado de adaptación durante el episodio de sequía de 2015-19 en relación a las medidas implementadas. Para ello se ha consultado y revisado diversas fuentes documentales. En primer lugar, normativas y leyes que regulan los recursos hídricos en términos de disponibilidad y demandas tanto en situaciones de normalida…
Laparoscopic Epigastric Hernia Repair
2016
Epigastric hernias are midline abdominal wall defects located between the umbilicus and the xiphoid process that do not resolve spontaneously. Symptomatic hernias require surgical repair.
Robotic-Assisted Neck Dissection: Our Experience
2021
Abstract Introduction Robotic neck dissection surgery allows less invasiveness to significantly improve the aesthetic impact even though it does not compromise the principles of radical cancer procedure. Objective The aim of our work is to describe our personal experience with robotic neck dissection surgery. Methods A retrospective study was conducted by analyzing 10 patients subjected to a robotic neck dissection surgery. In the period from August 2012 to December 2018, these patients have been treated exclusively with robotic lateral-cervical dissection. Five of them were subjected to robotic-assisted transaxillary neck dissection (RATAND) and the other 5 treated with robotic-assisted re…
