abstract introduction: nowadays, the advanced technology of designing electronic circuits in very small size and with very low power consumption has led to development of wearable and implantable medical devices. however, the electronic circuits need power supply that is usually provided by relatively large and heavy batteries. the discharged batteries have to replaced or recharged for long tim...
A conductometric biosensor using immobilised Chlorella vulgaris microalgae as bioreceptors was used as a bi-enzymatic biosensor. Algae were immobilised inside bovine serum albumin membranes reticulated with glutaraldehyde vapours deposited on interdigitated conductometric electrodes. Local conductivity variations caused by algae alkaline phosphatase and acetylcholinesterase activities could be ...
Johne's disease (JD) is one of the most costly bacterial diseases in cattle. In the U.S., economic losses from the disease have been estimated to exceed $1,500,000,000 per year, mainly from the effects of reduced milk production. Current diagnostic tests for JD are laboratory based and many of those tests require specialized equipment and training. Development of rapid and inexpensive diagnosti...
Abstract In the paper, a new 3D energy harvesting system is provided. This work discussed Lagrange approach to derive differential equations of motion in case systems. An electromechanical consists mechanical resonator, piezoelectric transducer and electrical circuit with load resistor. A flexible slender rod clamped at bottom loaded by tip mass proposed as resonator. Moving space, it enables a...
The solution properties of some cationic polyelectrolytes with ammonium quaternary centers either attached to an acrylic macromolecular chain (polycation PDMAEMQ type) or in the backbone (polycation PCA type) have been measured in order to identify how charge density, polyelectrolyte concentration, solvent polarity as well as temperature influence their behavior in solution by viscometric, cond...
this study describes the design, construction and calibration of an adjustable three-point hitch dynamometer. the dynamometer frame design was based on an inverted u-shaped frame that was mounted between the tractor links and implement. the dynamometer frame design allows for use in both category i and ii three-point hitch systems because of its flexibility in a lower point hitch spread and mas...
Many research studies have been conducted on the use of conjugated polymers in the construction of chemical sensors including potentiometric, conductometric and amperometric sensors or biosensors over the last decade. The induction of conductivity on conjugated polymers by treating them with suitable oxidizing agents won Heeger, MacDiarmid and Shirakawa the 2000 Nobel Prize in Chemistry. Common...
IV. Pressure Drop Definition In our experiments we measure the total pressure drop across the axisymmetric abrupt contraction-expansion geometry. We then systematically correct this to report an ‘extra pressure drop’ associated with the contraction-expansion alone. Table 1 shows the axial distance of each possible pressure transducer location from the contraction plane. For clarity, it is usefu...
The current study aimed to examine how various growers in the Czech Republic hop-growing regions approached production of hops (Saaz variety). work also keeps track different approach fertilization and nutrition, as well often plant protection chemicals containing these ingredients are used. Saaz hop variety samples from primary regions, gathered 2020 2021, were assessed. average spindle length...
Perovskite oxide ceramics have found wide applications in energy storage capacitors, electromechanical transducers, and infrared imaging devices due to their unique dielectric, piezoelectric, pyroelectric, and ferroelectric properties. These functional properties are intimately related to the complex displacive phase transitions that readily occur. In this study, these solid-solid phase transit...
