Simulated eutrophication and browning alters zooplankton nutritional quality and determines juvenile fish growth and survival
2018
Source at https://doi.org/10.1002/ece3.3832. The first few months of life is the most vulnerable period for fish and their optimal hatching time with zooplankton prey is favored by natural selection. Traditionally, however, prey abundance (i.e., zooplankton density) has been considered important, whereas prey nutritional composition has been largely neglected in natural settings. High‐quality zooplankton, rich in both essential amino acids (EAAs) and fatty acids (FAs), are required as starting prey to initiate development and fast juvenile growth. Prey quality is dependent on environmental conditions, and, for example, eutrophication and browning are two major factors defining primary produ…
Strictly convergent algorithm for an elliptic equation with nonlocal and nonlinear boundary conditions
2012
The paper describes a formally strictly convergent algorithm for solving a class of elliptic problems with nonlinear and nonlocal boundary conditions, which arise in modeling of the steady-state conductive-radiative heat transfer processes. The proposed algorithm has two levels of iterations, where inner iterations by means of the damped Newton method solve an appropriate elliptic problem with nonlinear, but local boundary conditions, and outer iterations deal with nonlocal terms in boundary conditions.

Expression of hMLH1 and hMSH2 proteins in ameloblastomas and tooth germs
2017
Background Mismatch repair proteins (MMRPs) are a group of nuclear enzymes that participate in the repair of base mismatches that occur during DNA replication in all proliferating cells. The most studied MMRPs are hMSH2 and hMLH1, which are known to be highly expressed in normal tissues. A loss of MMRPs leads to the accumulation of DNA replication errors in proliferating cells. Ki-67 is a biomarker regarded to be the gold-standard tool for determining cell proliferation by immunohistochemical methods. The aim of this study was to investigate the immunohistochemical expression of hMLH1, hMSH2 and Ki-67 proteins in ameloblastomas and tooth germs, to contribute to the understanding of the deve…
Bleomycin: Action on growth of oncogenic RNA viruses and on cell transformation
1975
Bleomycin (BLM) inhibits cell proliferation of noninfected chick embryo fibroblasts by blocking their DNA synthesis selectively. Chick embryo fibroblasts have beentransformed by Schmidt-Ruppin D strain of Rous Sarcoma Virus. Transformation has been determined by a focus assay. Foci formation is strongly reduced by BLM. Virus replication is inhibited by BLM in growing and confluent monolayer cells. This result might be explained by the observation that this drug reduces proliferation of growing and of confluent monolayer cells very sensitively. During the first 24 hours after infection the BLM inhibitory effect is more pronounced than in the case of BLM-application during the period 24--48 h…
Entrepreneurial strategies of Etna wine farms
2014
Viticulture, as well as agriculture in general, performs an environmental and landscaping function and it encourages rural development through the creation of income and job opportunities in the areas where wine is produced. The wine sector, in fact, is of great social and economic importance within the Sicilian agriculture and food industry, because of the job opportunities it provides and due to Sicilian pedoclimatic peculiarities, variety of grape wines cultivars and production process. The present study aims at assessing the competitiveness of small and medium-sized enterprises that cultivate wine grapes in the Etna area. In particular, it has been examined a sample of wine farms that p…
A new look at global growth convergence and divergence
2014
A key question in economics is whether poor countries will automatically close the income gap with rich countries. However, different empirical methods yield different answers – growth regressions suggest convergence, whereas tests of distribution dynamics suggest divergence. This column discusses recent research that reconciles these two strands of the literature. It extends the benchmark growth regression model to include a parameter that determines the share of new technologies a country can adopt each year. The result is that, although each country converges to a growth path, the growth paths themselves may diverge
Clubs de convergence et effets de débordements géographiques : une analyse spatiale sur données régionales européennes, 1980-1995
2007
Our article offers an econometric model of spatial interactions for the empirical analysis of growth in European regions over the period 1980-1995. The model detects spatial spillover effects and makes it possible to take account of the European economy’s strong polarization. More specifically, by factoring in both spatial autocorrelation and spatial heterogeneity, we characterize the economic polarization pattern in European regions, identify convergence clubs, and model them as spatial regimes. We estimate a two-regime model with spatially autocorrelated errors and show that the convergence process differs between the two regimes. We find a strongly significant spatial spillover effect : …
Enterovirus-induced non-acidic entry pathway and its relation to the epidermal growth factor receptor pathway

“I want creative neighbours”. Do creative service industries spillovers cross regional boundaries?
2014
The occurrence of creative service industries (CSI) is a strong determinant of differences in wealth amongst European regions. However, it is unknown if the strong effects are limited to occurring within regional boundaries or whether there are spillover effects into neighbouring regions. The purpose of this paper is to assess the existence of CSI spillover effects on the wealth of neighbouring regions. CSI and spillovers are integrated into both an empirical model and an endogenous growth model. Both models are estimated for a sample of 250 regions in the European Union in 2008. We find that most of the effects of CSI take place within regions, although there is also evidence that CSI has …
