Rosemary Essential Oil Microemulsion for Fungal Keratitis Treatment
Chemistry &Biodiversity, EarlyView.ABSTRACT This study investigated the use of Rosmarinus officinalis (rosemary) essential oil in a microemulsion (ME) formulation for the treatment of ocular fungal keratitis, a serious infection that can lead to blindness. The ME was characterized in terms of pH, stability, homogeneity, osmolarity, and other physicochemical properties.

On The Existence of Highly Condensed Sulfatotungstates and Sulfatomolybdates
ChemistryEurope, EarlyView.GA: The very first sulfatotungstates and sulfatomolybdates with two‐ and three‐dimensional condensed anions show a remarkable thermal stability and may open the door to a new class of condensed antenna phosphors with reduced vibrational quenching. We also focus on their optical properties and their phase‐pure synthesis at comparably mild temperatures ...

Öko-Legehennen: Ressourceneffizienz und Umweltschutz versus Auslaufmanagement und Flächenbeimessung [PDF]
, 2017 The minimal pasture size of 4 m² per hen for free range laying hens proves to be critical when seen under aspects of environmental protection. Taking a flock size of 1.000 laying hens and a pasture size of 4 m² per animal as a basis and assuming that ...

Implications for welfare, productivity and sustainability of the variation in reported levels of mortality for laying hen flocks kept in different housing systems: A meta-analysis of ten studies [PDF]
, 2016 Data from ten sources comprising 3,851 flocks were modelled to identify variation in levels of mortality in laying hens. The predicted increase with age was curvilinear with significant variation between the seven breed categories. Mortality was higher
