High-performance next-generation sequencing (NGS) technologies are advancing genomics and molecular biological research. However, the immense amount of sequence data requires computational skills and suitable hardware resources that are a challenge to molecular biologists. The DNA Data Bank of Japan (DDBJ) of the National Institute of Genetics (NIG) has initiated a cloud computing-based analyti...
Precise calculation of inlet pressure into sprinkler laterals is an important problem for proper distribution of uniformity. The adjusted average friction correction factor, FaAVG , provides the possibility of calculating the inlet pressure to mutli-outlet pressurized irrigation pipelines when the first outlet spacing from the pipe entrance is arbitrary. To investigate the effect of allowable h...
NIRSpec is a multi-object spectrograph (up to ∼ 100 objects) with a large field of view (∼ 10 square) and a detector response covering nearly a factor of 10 in wavelength (0.6 − 5μm). It will be employed on a segmented off-axis telescope in deep space. The combination of these factors results in a number of unique challenges for the calibration of the NIRSpec instrument. In this paper we outlin...
an experiment featuring waterhammer in viscoelastic pipes is presented in which the effects of pipe-wall viscoelasticity on waterhammer pressures are investigated. a large-scale pipeline apparatus made of polyvinyl chloride (pvc) at deltares, delft, the netherlands, has been used to carry out waterhammer experiments. tests have been conducted in a reservoir-pipeline-valve system consisting of a...
A Generalized Additive Model (GAM) is proposed to predict the pressure drop in a gas–liquid two-phase flow at horizontal, vertical, and inclined pipes based on 21 different dimensionless numbers. It fitted from 4605 points, considering fluid pattern classification as Annular, Bubbly, Intermittent, Segregated. The GAM non-parametric method reached high prediction capacity allowed great degree of...
This work presents modeling, simulation, fabrication, and testing of a novel flow-based electromagnetic energy harvester (F-EMEH) for producing usable electrical from the pulsating fluid pressure levels within pipeline. The power produced by developed can be effectively utilized operation wireless monitoring system pipeline networks. devised F-EMEH consists stationary magnet positioned in upper...
in this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. to analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...
background: the effective therapeutic dose of pralidoxime methylsulphate for organophosphate (op) poisoning is necessary to be clarified. this study was designed to comparatively assess the blood level of pralidoxime (bpl) and clinical outcomes in op poisoned patients treated with intermittent dosing and patients treated with continuous infusion. methods: this was a prospective, open labelled, ...
