Nitrogen and carbon in forro-alloy
BUNSEKI KAGAKU, 1958 第1報につづいて同じ装置を使用し,酸素ガスあるいは混合助燃剤を用いるなど,燃焼条件を変えることによって,燃焼法による金属中の窒素の定量法を検討した.試料としては,ケルダール法において残留物処理の必要なフェロアロイを用いた.低圧酸素ガス中で酸化鉛を助燃剤として燃焼させる方法により,フェロシリコン中の窒素,炭素の定量を行い,また鋼やチタンのように燃焼しやすい試料は,第1報に報告したように酸化鉛だけを用いる方法で窒素の定量ができることを確認した.またフェロクロムは燃焼しがたい試料であるが,助燃剤として鉛丹と無水硼酸を併用し,かつ試料を100メッシュ通過の細粒とすることにより,窒素,炭素の定量をすることができた.

Physiologia Plantarum, Volume 176, Issue 3, May/June 2024.Abstract Metacaspases are cysteine proteases present in plants, fungi and protists. While the association of metacaspases with cell death is studied in a range of organisms, their native substrates are largely unknown. Here, we explored the in vivo proteolytic landscape of the two metacaspases, CrMCA‐I and CrMCA‐II, present in the green freshwater alga

Horné Srnie: Emulation of Carpathian insignia during the Urnfield inflation
Archaeometry, Volume 66, Issue 2, Page 380-393, April 2024.Abstract Double‐armed insigniae of the Carpathian type are mysterious ceremonial symbols of the Urnfields representing the connection between ideological principles in the Western Carpathians. The Horné Srnie metal hoard shows that early Lusatian mountain communities developed an emulation strategy c.1325 BCE that shifts the origins of Lusatian ...

Environmental Toxicology and Chemistry, Volume 43, Issue 2, Page 418-428, February 2024.Abstract Zooplankton are a conduit of energy from autotrophic phytoplankton to higher trophic levels, and they can be a primary point of entry of microplastics into the aquatic food chain. Investigating how zooplankton communities are affected by microplastic pollution is thus a key step toward understanding ecosystem‐level effects of these global and ...
