BACKGROUND Discharging the oily wastewater in the environment causes serious problems, because of the oil compounds and organic materials presence. Applying biological methods using the lipase enzyme producer microorganisms can be an appropriate choice for treatment of these wastewaters. The aim of this study is to treat those oil wastewaters having high concentration of oil by applying lipase ...

Advanced wastewater treatment using membranes are popular environmental system processes since they allow reuse and recycling. However, fouling is a key limiting factor and so proprietary systems such as Avanti's RPU-185 Flexidisks membrane bioreactor (MBR) use novel rotating membranes to assist in ameliorating it. In earlier research, this rotating process was studied by creating a simulation ...

A 4-year-old boy was admitted to our hospital because of sudden-onset abdominal pain that lasted 5 hours. He had no prior history or signs of fever, vomiting, diarrhea, or currant-jelly stools. A physical examination revealed no rebounding tenderness or palpable abdominal mass. A standing plain film of the abdomen revealed no signs of intraperitoneal free air or intestinal obstruction. Intussus...

In the framework of program initiated at N.I. Vavilov All-Russian Institute Plant Genetic Resources (VIR), nomenclatural standards five domestic black currant cultivars have been prepared. The present paper presents these bred VIR: ‘Binar’, ‘Veloy’, ‘Peterburzhenka’, ‘Poeziya’ and ‘Trilena’. morphological traits breeding characters are described. Iinformation is provided on formation developmen...

It is assumed that microbial communities involved in the biological treatment of different wastewaters having a different chemical composition harbor different microbial populations which are specifically adapted to the environmental stresses encountered in these systems. Yet, little is known about the composition of these microbial communities. Therefore, the aim of this study was to assess th...

The goal of the current research was to synthesis zinc oxide nano-particles (ZnONPs) via simple, cheap and eco-friendly method which include reduction acetate dehydrate ZnONPs by using black currant aqueous extract (BC) as a reducing-agent. characterization stability, size, morphology, present functional groups on surface synthesized ZnOBCNPs were achieved SEM, X–ray diffraction, FTIR spectrosc...

The results of the study black currant varieties collection FSBSI FRC Horticulture, located in Bryansk region, by large-fruiting are presented. Genetic sources have been identified for inclusion breeding process to increase average weight berries (Lentyai, Titania, Gamayun, Dobry Gin, Podarok Veteranam, Astakhova, Kudmig, Debryansk, Bryanskiy Agat, Dar Smolyaninovoy, Kudesnik, and others). most...
