Trapping and mobilization of residual fluid during capillary desaturation in porous media

1998

We discuss the problem of trapping and mobilization of nonwetting fluids during immiscible two-phase displacement processes in porous media. Capillary desaturation curves give residual saturations as a function of capillary number. Interpreting capillary numbers as the ratio of viscous to capillary forces the breakpoint in experimental curves contradicts the theoretically predicted force balance. We show that replotting the data against a novel macroscopic capillary number resolves the problem for discontinuous mode displacement.

Gestión y liderazgo del talento: las claves del éxito empresarial

2021

Desde hace ya unas décadas, se está trabajando con profundidad en la investigación científica sobre la evidencia en las empresas de la gestión del talento. A nivel profesional, ya han sido muchas organizaciones las que han dado el salto cualitativo hacia una nueva manera de enfocar los recursos humanos (RR. HH.). Principalmente porque esta nueva perspectiva está más vinculada tanto al negocio como a los objetivos empresariales, además de ser más aceptada por la mayoría de los profesionales. Desde los orígenes de la guerra del talento por Mckinsey hasta la actualidad, la investigación está analizando el papel de la gestión del talento en los resultados organizativos. En este sentido, Luna (2…

Influence of 150 Years of Land Use on Anthropogenic and Natural Carbon Stocks in Emilia-Romagna Region (Italy)

2011

Changes in land use/cover that are commonly associated with urbanization can dramatically influence the amount, chemical form, and spatial distribution of carbon (C) stocks. Measured values and relative literature for composition of natural and anthropogenic materials have been compiled. These data are used in conjunction with land cover statistics and expert assessment of building design to calculate C stocks associated with 150 years of land use change and development for an area of the Po River Valley, Northern Italy. Using 4 time periods (1853, 1954, 1976, and 2003), we demonstrate that the C stocks within this densely populated area have undergone considerable modification. A 52% incre…

Thresholds for impaired species recovery

2015

Studies on small and declining populations dominate research in conservation biology. This emphasis reflects two overarching frameworks: the small-population paradigm focuses on correlates of increased extinction probability; the declining-population paradigm directs attention to the causes and consequences of depletion. Neither, however, particularly informs research on the determinants, rate or uncertainty of population increase. By contrast, Allee effects (positive associations between population size and realized per capita population growth rate, r realized , a metric of average individual fitness) offer a theoretical and empirical basis for identifying numerical and temporal threshol…

Indicateurs sur les inégalités du capital humain

2007

07095; Cette contribution a pour objectif de construire un indicateur sur les inégalités du capital humain, calculé à partir de la combinaison de deux sous-indicateurs d'inégalités. Le premier concerne le coefficient de Gini basé sur le nombre d'années scolaires. Le second prend en compte quatre autres dimensions des inégalités.

Global Demand for Paper Products: 2006–2050

2012

Our aim is to formulate and present global demand forecasts for several paper products for the main regions of the world for the period 2005-2050. Our forecasts, while based on standard regression modeling, differ from existing ones in that they are based not only on historical observed consumption patterns and projections of economic growth, but also take into account changes in the demographic constitution of countries and regions, and incorporate the assumption that beyond certain level economic prosperity (here in terms of GDP per capita) does not translate into increased demand for paper products. Our key results are threefold. First, the demand for paperboard and hygiene products will…

Drivers of greenhouse gas emissions in the Baltic States: A structural decomposition analysis

2014

Since the mid-1990s three Baltic States have significantly increased their per capita gross domestic product (GDP) and at the same time have managed to keep the CO2 equivalent (CO2e) emissions low. We used structural decomposition analysis to identify the drivers of change for CO2e emissions in these countries between 1995 and 2009, a period that includes the collapse of the Soviet Union, restructuring and economic growth and the great recession. The results show that final demand has been the main driving force for increasing emissions in the Baltic States and would have caused an 80%, 64% and 143% emission increase in Estonia, Latvia and Lithuania, respectively, all other factors kept con…

Optimal growth and land preservation

1997

A model of optimal economic growth with a constant population subject to a constraint on the availability of land is presented. It takes account of the dual character of land as a production factor and as a consumption good (environmental amenities) by determining the optimal intertemporal allocation of land between productive and recreational uses. An extension of the analysis for the case of a growing population with endogenous growth based on human capital accumulation shows that if the rate of discount is not very low then there exists a set of balanced growth paths compatible with a constant allocation of land. En este trabajo se presenta un modelo de crecimiento económico óptimo con u…

Household carbon footprints in the Baltic States: A global multi-regional input–output analysis from 1995 to 2011

2017

The paper analyzes consumption related household CO2 equivalent (CO2e) emissions for the three Baltic States – Estonia, Latvia and Lithuania from 1995 to 2011. The analysis is based on a multi-regional input–output model, which allows us to estimate life-cycle emissions for all major household consumption items. Results demonstrate that household carbon footprints in all the Baltic States significantly increased by 47% in Estonia, 20% in Latvia and 52% in Lithuania during the study period. In 2011 in Estonia expenditures for housing and utility contributed the highest per capita life-cycle emissions – 43%. However, in Lithuania housing accounted only for 16% of per capita emissions, but foo…
