Research ArticleOpen accessIn the keywordsFrequency Behavior of a Quartz Crystal Microbalance (Qcm) in Contact with Selected SolutionsZ. A. Talib, Z. Baba, S. Kurosawa et al.A device was constructed to monitor viscosity of solutions using fundamental frequency of 9 MHz and 10 MHz quartz crystal. Piezoelectric quartz crystals with gold electrodes were mounted by O-ring in between liquid flow cell. Only one side of the crystal was exposed to the solutions which were pumped through silicon tube by a peristaltic pump. The measured frequency shift … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 7,514 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOn-board Computer Unit Development for Precision Fertilization in Oil Palm Plantations Based on Data from a Precision Agriculture PlatformIndra Permana Solihin, Kudang Boro Seminar et al.This study aims to develop the function of the On-Board Computer Unit (OBC) device to control the Variable-Rate Fertilizer Application (VRFA) device according to the recommendations of the precision agriculture platform for oil palm (Precipalm) platform integrated into the tractor system.

Research ArticleOpen accessIn the abstractCoupling Analysis of Thermodynamic Equilibrium of Mass Transfer and Microbial Community Succession in Multiphase System of Dark Tea Solid-State FermentationZhanjun Liu, Jiawei Sun, Taotao Li et al.During the solid-state fermentation of dark tea, the limited material migration, the dynamic evolution of the thermodynamic equilibrium state, and the highly dynamic succession of the microbial community make it difficult to analyze the quality formation mechanism systematically. Traditional research has focused on microbial diversity or sensory quality analysis, lacking a systematic discussion on the regulatory effects of material migration … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 10 Aug 2026 · 1,004 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWIRELESS SENSOR NETWORKS FOR MEASURING THE CONSUMPTION OF SAVE WATER TAPSInacio Henrique Yano, Vitor Chaves de Oliveira, Eduardo Veiga de Araujo et al.Currently, water consumption is on the agenda of most organizations around the world. Beyond the environmental benefits for a better use of natural resources there is also a financial motivation to continuously reduce operation costs. This study reports a cost-effective solution using a Wireless Sensor Network (WSN) for measuring the consumption of different types of save water taps, in a … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 1 Apr 2014 · 6,854 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Development of A New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part I: Design of the Detection System and ApplicationsEric Carnes, Ebtisam WilkinsA portable, flow-through amperometric immunoassay system utilizing a newly designed immunosensor has been developed for the detection of bacteria. A sandwich scheme of immunoassay involving two stages of immunoreaction was employed using Escherichia coli as a model. E. coli antibodies were immobilized on Toray carbon paper to create a disposable immunofiltration membrane. Detection of the bacteria was achieved through the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2006 · 6,363 accessesView PDF Cite
