Hyphal budding bacteria were observed by electron microscopy in thin sections of surface material from Baltic Sea ferromanganese concretions. Similar bacteria were also observed in and isolated from enrichment cultures prepared from the same concretion material. Three morphologically similar strains of Mn-Fe-depositing budding bacteria were isolated from the enrichment cultures. Strain B-4 poss...

Abstract Photochromic wood was fabricated by coating microencapsulated photochromic material (MP)/polydimethylsiloxane composites onto using a simple drop-coating method. Urea-melamine–formaldehyde resin used to microencapsulate the (PM) via in situ polymerization. The concentration of MP affected property surface. total color change (? E *) reached 82.2 when composite is 8%. Adhesion tests con...

Abstract Thermoplastics combine high freedom of design with economical mass production. Metallic coatings on thermoplastics enable power and signal transmission, shield sensitive parts inside housings can reduce the temperature in critical areas by functioning as a heat sink. The most used technical are polyamides (PA), while described use cases often realized using Cu. Consequently, several st...

In fish, the relative amount of tissues of different densities changes significantly over short periods throughout the year, depending on the availability of food, nutrition and their developmental status, such as sexual maturation. If a land-living animal accumulates fat it influences not only its general state of health, but also markedly increases its energy expenditure for locomotion owing ...

When James Watson and Francis Crick reported the structure of DNA in 1953, the mechanism of inheritance was instantly apparent. The complementary pairing of the DNA bases in the double helix, the pair famously wrote, “immediately suggests a possible copying mechanism for the genetic material.’’ The structure helped explain one of the central problems of modern biology: how does genetic material...
