Anti-Adhesive Surfaces Inspired by Bee Mandible Surfaces.

Propolis, a naturally sticky substance used by bees to secure their hives and protect the colony from pathogens, presents a fascinating challenge. Despite its adhesive nature, honeybees adeptly handle propolis with their mandibles. Previous research has shown a combination of an anti-adhesive fluid layer and scale-like microstructures on the inner surface of bee mandibles.

Why did Trump call prayers politically correct? The coevolution of the PC notion, the authenticity ethic, and the role of the sacred in public life.

Trump's crusade against PC played a key role in his political rhetoric and resonated well among his supporters, yet his notion of PC differed greatly in meaning from earlier uses of the term and was used to denounce a much wider range of socio-political behaviors. Based on a systematic analysis of Trump's use of this notion, I identified five main normative propositions organizing Trump's anti-PC rhetoric. Viewed together, these propositions add up to a rehabilitation of White working-class culture but also outline an emerging late-modern version of the authenticity ethic, whose power extends far beyond the working class.

Interaction between honeybee mandibles and propolis.

In a biomimetic top-down process, challenging the problem of resin deposition on woodworking machine tools, an adequate biological model was sought, which hypothetically could have developed evolutionary anti-adhesive strategies. The honeybee () was identified as an analogue model since it collects and processes propolis, which largely consists of collected tree resin. Propolis is a sticky substance used by bees to seal their hive and protect the colony against pathogens.

[Treatment of Fractures of the Distal Third of Tibia Diaphysis by MIPO Technique].

PURPOSE OF THE STUDY MIPO (Minimally Invasive Plate Osteosynthesis) technique is currently a commonly used method to treat fractures of the distal third of tibia diaphysis. At the same time, it is just like other methods accompanied by a relatively high complication rate. The purpose of this study was to determine whether the use of this technique at our department is effective and whether the complication rate does not differ considerably from values reported by literature.

[Results of Surgically Treated Patients for Hip Fracture - Complications, Mortality].

PURPOSE OF THE STUDY Our main objective was to evaluate the mortality and complications of patients following surgical treatment of hip fractures and to identify the associated risk factors for postoperative mortality. MATERIAL AND METHODS We retrospectively reviewed all patients over the age of 50 who underwent surgical treatment for femoral neck and peritrochanteric fractures at our institution in 2003 and 2013. Mortality was compared between subgroups classified by age, gender, fracture type, method of treatment.
