Boron trifluoride coatings for thermoplastic materials and method of applying same in glow discharge [PDF]

open access: yes, 1978
Plastic surfaces can be improved physically and optically by treating them with a plasma of boron trifluoride. The trifluoride can be the sole reactant or be part of a mixture also containing an organic monomeric substance such as perfluorobutene-2 or an

Humic substances [PDF]

open access: yesEnvironmental Science and Pollution Research, 2007
Freshwater bodies which chemistry is dominated by dissolved humic substances (HS) seem to be the major type on Earth, due to huge non-calcareous geological formations in the Northern Hemisphere and in the tropics. Based on the paradigm of the inertness of being organic, direct interactions of dissolved HS with freshwater organisms are mostly neglected.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Inventory reporting of livestock emissions: the impact of the IPCC 1996 and 2006 Guidelines

open access: yesEnvironmental Research Letters, 2021
The livestock sector is a major contributor to agricultural greenhouse gas (GHG) and nitrogen (N) emissions and efforts are being made to reduce these emissions. National emission inventories are the main tool for reporting emissions.

Interpolation in local theory extensions [PDF]

open access: yes, 2008
In this paper we study interpolation in local extensions of a base theory. We identify situations in which it is possible to obtain interpolants in a hierarchical manner, by using a prover and a procedure for generating interpolants in the base theory as

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Gas exchange and organic matter production of Scots pine (Pinus sihestris L.) seedlings grown in water culture with ammonium or nitrate form of nitrogen

open access: yesActa Societatis Botanicorum Poloniae, 2015
he reaction of Scots pine (Pinus silvestris L.) seedlings to ammonium and nitrate form of nitrogen was investigated. Rates of photosynthesis and respiration, content of chlorophylls, and accumulation of organic substance were determined in 12 and 18 ...
