Numerical Simulation of Over Reading Coefficients of Wet Natural Gas Measurement Based on the Venturi Tube

Shiyou jixie, 2023
Studies on over reading for wet natural gas and actual operation conditions are rarely reported.Given this,the numerical simulation of the pure gas,pure liquid,and gas-liquid dual-phase flow in the Venturi tube is performed using the software Fluent,and ...

The performance of the sludge pretreatment system with venturi tubes

Water Science and Technology, 2008
This research investigates the feasibility of the venturi cavitation system (VCS) for the sludge pretreatment to increase biodegradability. The performances of the VCS depended on the inclination angle of the venturi outlet, and better results obtained with 12° than with 8° or 15°. Although it is energy efficient to use several venturies in series, the

Venturi tube calibration for airflow and volume measurement [PDF]

Flow Measurement and Instrumentation, 2018
Abstract Ventilation measurement by Venturi meters (Vm) has not been validated for human ventilation application in basic and applied physiology. This project aimed to demonstrate the feasibility of the Vm as an inexpensive, robust method for inspiratory ventilation measurements used in Indirect Calorimetry.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

A Review of Breath Sensing for Disease Monitoring and Diagnosis: Breathomics, Artificial Intelligence, and Nanomaterials for the Future of Medicine

Advanced Sensor Research, Volume 5, Issue 7, July 2026.
Breathomics is established as a non‐invasive diagnostic strategy by combining volatile organic compound biomarkers, nanomaterial‐based sensor arrays, and AI‐driven classification. Key diseases, sensing materials, and analytical challenges are critically compared, revealing how portable, data‐enabled breath platforms are moving toward clinically useful ...

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, Volume 82, Issue 7, Page 7123-7136, July 2026.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

Intravenous lanadelumab for the treatment of moderately ill COVID‐19 patients

British Journal of Clinical Pharmacology, Volume 92, Issue 6, Page 1685-1695, June 2026.
Aims Kallikrein‐kinin system (KKS) dysregulation is hypothesized to play a pathogenetic role in COVID‐19‐associated pulmonary oedema. To investigate the efficacy and safety of intravenous lanadelumab, a monoclonal antibody that inhibits plasma kallikrein, in COVID‐19, we conducted a phase 2, open‐label, randomized‐controlled, proof‐of‐concept ...
