The Atchafalaya River in Louisiana shares the third largest drainage basin in the world with the Mississippi River. Sediment cores and seismic profiles were used to examine the development and impact on land accretion of an early-stage subaqueous delta accumulating on the shallow (b25 m water depth) continental shelf seaward of the Atchafalaya River mouths in the period (~100 years) since the A...

Phototrophic and heterotrophic nanoplankton (PNAN, HNAN; 2–20 mm protists) and microplankton (PMIC, HMIC; 20–200 mm protists and micrometazoa) are major taxa involved in partitioning carbon and energy within the pelagic food web. In the Ross Sea, Antarctica, plankton biomass appears to be controlled by the seasonal recession of the sea ice and the formation of the Ross Sea polynya during the sh...

Let R be an integral domain and let f(X) be a nonzero polynomial in R[X ]. The content of f is the ideal c(f) generated by the coefficients of f . The polynomial f(X) is called Gaussian if c(fg) = c(f)c(g) for all g(X) ∈ R[X ]. It is well known that if c(f) is an invertible ideal, then f is Gaussian. In this note we prove the converse. Let R be a ring, that is, a commutative ring with unity. Le...

The landscape of systemic therapies (ST) for advanced hepatocellular carcinoma (HCC) pts has evolved in recent years. So far, the IMbrave 150 study (NCT03434379; Finn RS NEJM 2020), with combination atezolizumab (atezo) + bevacizumab (bev), obtained best results regarding overall survival (OS) and progression free (PFS) treatment naïve pts. Still, data from real life scenario on safety efficacy...

This paper evaluates and compares the main philosophic economic thoughts of two great liberal minds Michael Polanyi Friedrich A. von Hayek in regards to concept a ‘spontaneous order’. In several their books papers, both Michal (1941, 1948, 1951) F.A. (1944, 1945, 1964, 1973) strongly emphasised on impossibility socialism superiority free market versus public interventionism. Both highlighted co...

Million tons of waste glass are produced worldwide every year, which creates that does not dissolve in the soil and decompose environment. The composition contains silicon oxide, so it is fully justified to use as a building material. It possible contribute development environmentally friendly, energy efficient green technologies by finely grinding using i concrete partial replacement cement we...

Background Over the last 20 years aggressive therapy for inflammatory joint diseases (IJD) has become standard of care following acceptance Methotrexate as anchor drug and extensive use biologic since 2003. Immunosuppression increases risk common uncommon infections (1). Objectives To compare temporal rates associated mortality hospitalisation with opportunistic (OI) (Table 1) IJD patients in W...
