SPRAY FOAM BASEMENT INSULATION: TORONTO Introduction Spray Foam Insulation (SFI,) also known as Polyurethane foam, is a very common practice among homeowners in the United States, UK, Canada, Australia, and some other countries. SFI is a heat-induced polymer – a spray-applied plastic with specially designed equipments capable of forming continuous insulation and serving as sealing barrier on walls, round corners, roofs, floor or ceiling cavity, as the case may be. It is produced by the mixture…

5.4. Electrosensitive hydrogels Hydrogel swells in response to an electrical stimulus with a mechanism very similar to pH, experiences shrinkage, and bending. The major difference between electrical and pH stimulations is that the electric field moves mobile ions in order to regulate an ion concentration gradient through the hydrogel and the solution [54,55]. Polymeric networks containing ionizable groups can have important electrical behavior under an electric field. The electrosensitive…

Introduction This practical was an investigation involving the use of a tennis ball and a meter ruler. The tennis ball was held and dropped at a specific height above the ground. The height of the bounce was then measured. This investigation was carried out to find out whether the efficiency of the bounce varied with the height of release of the tennis ball. If the bounce were 100% efficient, then the tennis ball would have bounce off the ground and return to the starting height. Research…

Superfluid helium or He II is a macroscopic quantum fluid that exhibits extraordinary properties. %By applying the limit of low flow velocities, The behavior of the fluid can be understood using a Landau - Tisza model, where He II is considered to be a two-component fluid with independent velocity fields: the inviscid superfluid of density $\rho_s$, and the normal fluid of density $\rho_n$, where the total density $\rho$ = $\rho_s$ + $\rho_n$ \cite{Tisza,Landau}. The superfluid has neither…

INTRODUCTION The science of magneto hydrodynamics (MHD) deals with geophysical, astrophysical and engineering problems since many years. This subject has attracted attention of many researchers in the MHD flow on Newtonian fluids on plate, cones and disks. Hari R [30] investigated the chemical and radiation effects on MHD casson fluid flow past an oscillating vertical plate embedded in porous medium. Subbaiah Naidu [70] studied the effect of Hall current on free convective flow of stratified…

Hello Steemians, guess it's time to drop my second STEM post. But first I'd like to recognize two individuals that may have helped me get the right start into the steem community, the persons of @sogless and @mrbreeziewrites. They've been of good guidance. Yeah, to the business of the day. Since I'm just getting to my third year in the University studying Mechanical Engineering, I should say I know just little in the world of Engineering until steemit kinda made me expose myself to that world…

Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. It involves not only laboratory measurements of various thermodynamic properties, but also the application of mathematical methods to the study of chemical questions and the spontaneity of processes. The structure of chemical thermodynamics is based on the first two laws of thermodynamics. Starting from the first…

Hooge’s relationship is an empirical relationship based on a large collection of data obtained for flicker noise in semiconductors and metal films. According to this model, the PSD of flicker noise is given by, S(f) = γHV 2 Ncf α Where Nc = ncΩ is the number of free charge carriers in the specimen,nc is the charge carrier density and Ω is the volume of specimen.γH is the Hooges constant, a parameter which characterizes the noise levels of a particular system. The initial value of gamma is…

current century, the primary energy sources being used have been harmful to our environment, and are nonrenewable. These energy sources are not going to be on earth forever, so it would be beneficial to mankind to find a new primary source of energy to replace the old ones. Solar power is one of the most abundant energy sources we have on Earth, and each year it is becoming more and more popular. With the technological advances in the modern world, solar power energy has the potential to become…

For example, a blown up balloon can either expand or shrinks depending on the collisions/pressure inside. When the temperature gets higher the particles move faster because they have more kinetic energy which causes more collisions leading into more pressure expanding on the balloon. Same goes for a cooler temperature, but the opposite happens, the particles move slower which causes less collisions, leading to less pressure pushing against the balloon…
