The genus Annona is confined almost entirely to tropical and subtropical America and the Caribbean region (Safford 1914). Edible species include Annona muricata L. (soursop), A. squamosa L. (sugar apple), A. cherimola Mill. (cherimoya), and A. reticulata L. (custard apple). Each geographical region has its own distinctive pest fauna, composed of indigenous and introduced species (Bennett & Alam...
Aims and background: Nausea and vomiting is one of the most common and most annoying post-operative complications, therefore, the aim of this study was to investigate the effect of oxygen therapy with Venturi mask and CPAP mask on nausea and vomiting after cesarean section. Materials and methods: This quasi-experimental study was performed on two groups (control-intervention) on 90 candidates ...
In oil and gas and geothermal installations, open channels followed by sieves for removal of drill cuttings, are used to monitor the quality and quantity of the drilling fluids. Drilling fluid flow rate is difficult to measure due to the varying flow conditions (e.g., wavy, turbulent and irregular) and the presence of drilling cuttings and gas bubbles. Inclusion of a Venturi section in the open...
venturi flumes are measurement structures commonly used in water systems to measure the flow discharge. some of them are not well installed or present some geometrical defects. the objective of this study is to investigate the hydraulic influence of a number of typical wrong installations and geometrical defects of long-throated venturi flumes: significant positive or adverse slopes, humps and ...
This work aim to produce high-concentration ozonated water using a dielectric barrier discharge for inhibiting the enzymatic browning of Mang-Koot-Cut. The ozonizer was composed radio frequency (RF) powered mesh electrode and grounded that sandwiched Pyrex glass tube as material. air flowing through generated ozone gas. optimal flow rate 2 L/min. A venturi injector caused an effective mixing be...
This paper proposes a technique for measurement of liquid flow using venturi and ultrasonic flow meter(UFM) to have following objectives a) to design a multi-sensor data fusion (MSDF) architecture for using both the sensors, b) improve sensitivity and linearity of venturi and ultrasonic flow meter and c) detect and diagnosis of faults in sensor if any. Fuzzy logic algorithm is used to fuse outp...
