Cadmium effects on p38/MAPK isoforms in MDA-MB231 breast cancer cells

2009

Emerging evidence seems to indicate that the heavy metal cadmium (Cd) is able to regulate gene expression, drastically affecting the pattern of transcriptional activity in normal and pathological eukaryotic cells, also affecting intracellular signalization events. Human p38 is a family of mitogen-activated protein kinases consisting of four isoforms (alpha, beta, gamma and delta) which mediate signal transduction cascades controlling several aspects of cell physiology. In this study we examined whether exposure of MDA-MB231 tumor cells from the human breast to Cd may exert some effect on p38 isoform expression and accumulation, as well as on p38 activation. Employing a combination of prolif…

“Building Integrated Photovoltaics and DSSC-Glassblocks"

2012

According to many market analysts, Building Integrated Photovoltaics (BIPV) represents the future of photovoltaic (PV) industry as well as one of the strategies for the achievement of zero-energy building standards and UE goals for the next years. Dye-sensitised solar cell (DSSC) is a low-cost and very versatile solar technology, offering a wide range of possibilities in terms of colour, transparency and design: hence DSSC are particularly suited for BIPV and could give a big contribution in this direction. Starting from those considerations, this paper will show the first results of a research aimed at the integration of DSSC with the glassblock for the construction of multifunctional tran…

Wpływ traktatu lizbońskiego na regulacje imigracyjne UE ze szczególnym uwzględnieniem zasady solidarności i sprawiedliwego podziału odpowiedzialności…

2018

Analysis of the influence of the Treaty of Lisbon on the EU immigration reguiations with particular attention to the principle of solidarity and fair sharing of responsibility between Member States indicates that the Treaty of Lisbon extensively reformed these reguiations. Its premise and mechanisms should be assessed as justified. However, they give a lot ofleeway for interpretation and need to be supplemented with EU secondary law. Unfortunately, States are primarily driven by their interest when applying these rules which leads to their nonproductiveness. The recent migration crisis explicitly proves this. The reason for the above can be found, among other things, in attachment to classi…

Studies on some antimony(III) complexes with tridentate schiff base ligands

1981

Abstract The antimony(III) complexes FSb(Sab), ClSb(Sab) and ClSb(Sat) containing dianonic, potentially tridentate Schiff-base ligands with ONO(Sab 2− ) and ONS(Sat 2− ) donor atoms have been prepared and characterized. The mass spectra of these derivatives are reported. The occurrence of chelation by the tridentate ligand is inferred from the infrared data. The antimony-121 Mossbauer parameters at 4.2 K are reported. The magnitudes and the positive sign of eQV zz suggest a consistent p-character of the antimony lone-pair orbital. Observed differencies in the isomer shift and eQV zz values are discussed on the basis of the likely distribution of electron density around antimony.

A Global Climatology of Tropical Moisture Exports

2013

Abstract In a recent paper, a climatology of tropical moisture exports (TMEs) to the Northern Hemisphere (NH) was constructed on the basis of 7-day forward trajectories, started daily from the tropical lower troposphere, which were required to reach a water vapor flux of at least 100 g kg−1 m s−1 somewhere north of 35°N. It was shown that TMEs contribute significantly to regional precipitation. Here, the authors complement and extend this work by (i) using 6-hourly European Centre for Medium-Range Weather Forecasts (ECMWF) Interim Re-Analysis (ERA-Interim) data from 1979 to 2010 instead of the earlier 40-yr ECMWF Re-Analysis (ERA-40), (ii) extending the climatology to the Southern Hemispher…

Identifying Rossby wave trains and quantifying their properties

2013

A novel method is introduced to automatically identify upper-level Rossby wave trains and to objectively diagnose their properties. Based on the envelope of the upper tropospheric meridional wind represented in a Hovmoller diagram, the algorithm identifies individual Rossby wave trains as objects. These depend to some extent on user defined parameters. The utility of the method is demonstrated in two areas of application. First, the skill of a particular numerical weather prediction model is analysed for a specific case of a long-lived Rossby wave train. For this purpose, a novel diagnostic is designed based on a Hovmoller diagram of the Rossby wave train objects that contains forecast data…

Long-lived Rossby wave trains as precursors to strong winter cyclones over Europe

2013

The statistical connection between strong surface cyclones over Europe and long-lived upper-tropospheric Rossby wave trains is examined for the Northern Hemisphere winter season using 45 years of reanalysis data. Dates are selected for which the surface pressure anomaly over Central Europe is below a threshold yielding the 5% of lowest values. Composites of upper tropospheric meridional wind for these dates (including a lead or lag in time) display clear signs of a wave train. The composite wave train lives for over two weeks and propagates eastward over more than 360° longitude. The phase speed of individual lows and highs, by contrast, is close to zero and the same is true for the composi…

Is Gayness a Test from Allah? Typologies in Muslim Stances on Homosexuality

2014

The article presents a spectrum of views within Muslim discourse on questions such as: “Is non-hetero predilection congenital and as such created by God?,” “Are non-hetero feelings/actions sinful as such?,” “Should the authorities in Muslim states punish homosexual acts?,” “Should lesbian and gay Muslims marry partners of the opposite gender?” The stances presented are based on texts by Yusuf al-Qaradawi, Heba Gamal Kotb, Abdelwahab Bouhdiba, Amreen Jamal and Scott Siraj al-Haqq Kugle. Stances presented by various Muslim internet sites are also considered. The review is grouped into a four-way typology: strongly traditional; moderately traditional; moderately progressive; and strongly progr…
