Electrochemical obtaining of nickel hydroxide from nickel plating waste water for application in the alkali secondary cells

V.L. Kovalenko, V.A. Kotok & V.V. Malyshev
The rinsing and waste water of the plating industry, containing the heavy metal cations, are the source of environmental pollution. Nickel cations have a strong biological hazard. At the same time, up to 30% of nickel compounds spent on nickel plating are irretrievably lost to the rinsing water. Purification of the rinsing and wastewater from heavy metal cations is expensive. It’s economically effective to develop the methods of local treatment of plating rinsing water with...

Влияние содержания тяжёлых металлов в воде малых рек, используемой для полива кукурузы армянской популяции

А.Р. Сукиасян
Экологическая безопасность малых рек для населения региона, их роль в формировании биоты во многом определяются химическим составом воды. При изменении интенсивности действия климатических и антропогенных факторов химический состав и, как следствие, качество воды могут существенно изменяться. В связи с этим проведение мониторинговых исследований состава воды этих источников представляется весьма актуальным. Изучены особенности миграции ряда тяжёлых металлов (ТМ) в триаде вода-почва-растение на примере однолетнего травянистого культурного растения – сахарной кукурузы, произрастающего на прибрежных территориях реки Шнох....

Л. М. Шапошникова
Исследовано влияние физико-химического состава радиоактивно загрязнённых почв на поглощение радия-226 иван-чаем узколистным (Chamaenerion angustifolium) и чиной (Lathirus pratensis, L. vernus). Методами корреляционного и регрессионного анализа выявлено, что валовое содержание радия в исследуемых техногенных почвах больше всего зависит от содержания в них органического углерода и фосфора, содержание подвижных форм (ПФ) радионуклида связано с такими физико-химическими характеристиками как содержание органического углерода, а также обменных катионов кальция и магния. Межвидовых различий в накоплении радия указанными растениями выявлено не...

Applying songbird population dynamics models to conservation biology needs

A. L. Podolsky
Proper understanding of the reproductive biology traits and population dynamics patterns of declining songbird species is crucial for ensuring their effective protection and recovery. Metapopulation dynamics may cause the extinction of local populations in some landscape patches regardless of the habitat quality and undertaken conservation measures. At the same time, the source-sink type of the population dynamics could saturate lower quality habitat patches with dispersing individuals from the population sources. Hence, poorer quality habitats presumed...

Возможность частичной замены антибиотиков биологически активными веществами при лечении клинических маститов у коров

М. А. Азямов
По информации Всемирной организации здравоохранения (ВОЗ) возрастает проблема антибиотикорезистентных штаммов золотистого стафилококка Staphylococcus aureus. Эти бактерии меняют свой геномный состав под воздействием антибиотиков и быстро распространяются в окружающей среде, создавая угрозу для здоровья человечества и продовольственной безопасности ряда стран. ВОЗ требует уменьшить употребление антибиотиков при маститах у коров на 50%. Золотистый стафилококк – преобладающий вид возбудителя маститов коров в странах Западной Европы и России. Почти в 90% больших ферм и комплексов, где используют антибиотики, регистрируется...
