abstract many studies have been conducted on the characteristics of hydraulic jump over gradually expanding cross sections, but comparatively few have been carried out on basins with convergent wall. in the present research, the hydraulic jump characteristic of the stilling basin with convergent wall has been investigated. the main objective of this research is evaluation of conjugate depths ra...

We present a verification algorithm that can automatically switch from RAM based verification to disk based verification without discarding the work done during the RAM based verification phase. This avoids having to choose beforehand the proper verification algorithm. Our experimental results show that typically our integrated algorithm is as fast as (sometime faster than) the fastest of the t...

We have shown previously that oncogenic Ras induces cell cycle arrest in activated Xenopus egg extracts [Pan, Chen and Lin (1994) J. Biol. Chem. 269, 5968-5975]. The cell cycle arrest correlates with the stimulation of a protein kinase activity that phosphorylates histone H2b in vitro (designated p96(h2bk)) [Chen and Pan (1994) J. Biol. Chem. 269, 28034-28043]. We report here that p96(h2bk) is ...

one of the great challenges in the processing of materials using equal channel angular pressing (ecap) is the high forming forces required to produce large shear deformation in the material. researchers show that the friction forces between the die and the sample constitute a great part of the total forming forces. recently, ultrasonic vibrations are successfully implemented into the ecap proce...

Purpose: to assess the state and operating conditions of fish passage channels Ust-Manych waterworks on river Western Manych. Materials methods. The factual basis for assessing was materials author’s survey field studies performed at given facility in 2022. were carried out according generally accepted methods conducting hydrometric measurements flow rate parameters geometric dimensions network...

Background Egg yolk is the main cryoprotectant agent in semen freezing extenders which is used in order to protect spermatozoa against cold shock. However elimination of animal bioproducts from the cryopreservation protocol is becoming mandatory. Therefore the aim of this study is to compare a previously studied homemade soya bean lecithin based extender with a commercially available extender f...

Among one of the main problems affecting Brazilian agriculture, we can mention transport water, since in many places it is necessary to lift and other areas. Equipment such as motor pumps being used. However, they present a high cost purchase equipment, addition using non-renewable sources. Aiming get around this fact, use hydraulic ram becomes viable alternative, low-cost equipment whose funct...

[1] In the past, texture-based classification of soils has been used for grouping soils in variably saturated water flow and solute transport studies. Classification of soils becomes especially important for large-scale studies where the spatial and temporal variability in the hydraulic properties of soils exceeds the field sampling capabilities. Although soiltexture-based classification has be...
