Fungal species Lasiodiplodia theobromae of family Botryosphaeriaceae is a pathogen causing significant loss production and quality mango crop in Vietnam worldwide. In this study, fungal strain designed as XB1 was isolated from stem-end rot fruits, identified tested its susceptibility to silver copper nanoparticles. Strain identification based on biological characteristics sequence analysis 5.8S...

Homeostasis, growth and reproduction in crustaceans are under endocrine control as is established in other animals. The identification of crustacean hormones and elucidation of mechanisms of hormonal regulation have been pursued extensively. Mechanisms are found to be partly similar to, but also considerably different from those in insects, although both groups of animals are arthropods. Moltin...

The work presents the design and fabrication procedures used to manufacture inexpensive iron-base powders employed as a matrix in diamond-impregnated tool components. Three newly developed low alloy steel powders, containing from 94.4 99.4 wt.% Fe, have been formulated with assistance of ThermoCalc software produced by means proprietary process patented AGH-UST. It has shown that are readily pr...

The mining of hard rocks by mechanical methods, using cutting tools, is associated with problems such as sparking, dust generation and increased wear. application disk tools allows limiting these but requires constructing a machine large dimensions weight. To limit problems, high-pressure water jets can be applied. article presents the effects this solution in field stand tests when symmetrical...
