Alkali-Polymer Flooding in an Austrian Brownfield: From Laboratory to Field-Insights.

We focus on optimizing oil displacement in brownfields using alkali polymers (AP) flooding. The goal is to enhance rock-fluid and fluid-fluid interactions to improve oil recovery. The evaluation includes detailed screening of AP mixtures to ensure cost-effectiveness and maximize chemical slug efficiency, using an AP pilot project in Austria as a case study.

Meaning and Clinical Interest of Minor Malformations and Normal Variants in Neonatology.

Congenital malformations can be found in all organ systems of a newborn. Almost two-thirds of congenital malformations have an unknown cause. There are minor (mM) and major (MM) congenital malformations.

Depression and stress levels in patients with different psychiatric disorders during concurrent early-phase COVID-19 pandemic and earthquake in Croatia.
