Liner is key parts of equipment of slab side pressing, its main function is supporting the weight of lateral pressure, and are under some impact pressure, which is impact force up to 2000 tons, it make liner frequent breakage in the process of working, an led to entire production line stop, seriously affect the yield and efficiency of hot rolled strip. In order to obtain the reasons of liner fr...

A low-frequency-assisted boring operation is a key cutting process in the aircraft manufacturing sector when drilling deep holes to avoid chip clogging based on breakage and, consequently, reduce temperature level process. This paper proposes predicted force model commercial control-supported breaking function without external vibration devices operations. The was fitted by conventional measure...

When UV-irradiated T4 bacteriophage (v(+)) infects in the presence of chloramphenicol, the phage DNA rapidly acquires single-stranded breaks proportional to the dose of UV. In contrast, when UV-irradiated T4 v(1) (radiation sensitive mutant) infects under identical conditions, the phage DNA remains integral. A series of coinfections with v(+) and v(1) phage (UV-v(1) + majority non-UV-v(+) and U...

The chromosomal breakage syndromes-ataxia-telangiectasia, Fanconi’s anemia, and Bloom’s syndrome-are associated with growth failure, neurologic abnormalities, immunodeficiency, and an increased incidence of malignancy. The relationship between these features is unknown. We recently evaluated a 21 -year-old female with more severe chromosomal breakage, immunodeficiency. and growth failure than i...

A population balance framework based on high order moment conserving method of classes is extended to capture surfactant dynamics and its effect drop size distributions. The proposed flexible for incorporating various closure models breakage coalescence, mass transfer, physical equilibria between dispersed continuous phase as well adsorption the interface. first schematically explained derived ...

For the purpose of exploring deformation characteristics of jointed rock masses, influence of joint inclination and confining pressure on the mechanical behavior of discontinuous rock a series of compression tests were conducted under satisfactory testing conditions on three types of sandstone from various locations. Three groups of jointed specimens were used in this research, including specim...

The gametocidal (Gc) chromosome from Aegilops spp induces chromosome mutation, which is introduced into common wheat as a tool of chromosome manipulation for genetic improvement. The Gc chromosome functions similar to a restriction-modification system in bacteria, in which DNA methylation is an important regulator. We treated root tips of wheat carrying Gc chromosomes with the hypomethylation a...
