Solubility property of ozone is dependent on several extrinsic factors such as temperature, pressure, composition of the medium, pH, gas flow rate, etc. Henry’s law says that the pressure of the gas exerts above the liquid is directly proportional to the solubility of the ozone (Bablon et al., 1991). De Smedt et al. (2001) revealed that solubility of ozone is dependent on pH, temperature and type of additives of the aqueous solution. Levanov et al. (2008) found that solubility of ozone decreased…

1 Introduction Interferometry is a measurement technique which utilizes the interference of waves in a medium to cre-ate interference patterns [5]. In general, the waves can be light, sound or radio waves. The interference pattern is detected by a photodetector and it provides some useful information about the properties of the object or phenomenon under test. Interferometers are used to make very small measurements that cannot be achieved with any other method. An important…

Piezoelectricity was discovered in1880 by Pierre and Jacques Curie, However the term piezoelectricity was coined by W.G. Henkel in 1881.G.Lippman discovered reverse process that is to say on application of electric field mechanical stresses could be developed in 1880 .Which was experimentally proven by curie brothers in 1881. Piezoelectric materials can be natural or synthetic. Natural occurring crystals include quartz, topaz, silk, wood etc. While as synthetic are quartz like, ceramic polymers…

Trichloroethylene (TCE) is defined as a Priority Pollutant covered under the Clean Water Act. The chemical is an organic vapor, and is a component used in degreasing, distillation, and painting operations (Woodside, 1999). Trichloroethylene is a liquid used as a solvent, and in other compounds (Environmental Protection Agency, 2011). Annually 10 million pounds of Trichloroethylene is used to manufacture Polyvinyl Chloride (PVC) (Gilbert & Heuvel, 2014). While current figures are not…

often a compromise between its solubilization potential for the drug and its ability to microemulsify. Results in table 1 represent the solubility of sulpiride into different oils, surfactants and co-surfactants. Non-polar solvents possessing low dielectric constants can dissolve non-polar solutes with similar internal pressures via induced dipole interactions [23]. Labrafil isostearique showed the greatest solubilization power for sulpiride (16.02…

INVESTIGATION OF ELECTRO-MECHANICAL FACTORS EFFECTING PIEZOELECTRIC ACTUATOR FOR VALVELESS MICROPUMP CHARACTERISTICS Abstract In this study, a new micropump was designed which is suitable for medical applications regarding size and flow rate. When a micropump is used to control the amount of drug delivery, the flow rate is a key parameter and can be controlled with the diaphragm displacement. The amount of displacement depends on the thickness of piezoelectric element, voltage,…

supercapacitors with incredible storage capacity. Much research and investment have been carried out in this impressive technology. It is same as that of the normal capacitor the only thing is it utilizes higher surface area electrode and thinner dielectric, which results in high capacitance. The value of this small device is immeasurable. They can charge and discharged over several rates without ill effects and can pack a couple of thousand farads in it. This paper gives an overview of research…

Q1.Ethernet has become the standard for LAN communications. Give a brief overview of structure of an Ethernet frame. Ethernet and Wi-Fi are the most commonly used technologies to set up Local Area Networks today. It operates by using Carrier Sense Multiple Access Detection (CSMA/CD) to control media access. (Study CCNA, 2016) The structure of an Ethernet Frame is as follows: The Ethernet Frame Structure (Anon., 2013) Explanation: • Preamble: This field is responsible for harmonizing bits…

Many people are concerned about the dangers that cell phones pose, and they are told that keeping it a greater distance from their heads and using devices such as headphones can diminish much of the radiation; all of which is true. Unfortunately, since the technology industry has made the invention of wireless headphones, if people use their cell phones in conjunction with these devices, the radiation dosage can be even greater than normal. Using Bluetooth, the main type of wireless…
