Creating Liquid from Non-liquid Foods

- For non-liquid foods, the microbial cells must be released from the food matrix into a liquid diluent or growth medium before separation and concentration can be attempted. Then the pathogenic target(s) can be identified and enumerated by either conventional or rapid detection techniques. Filtration has been suggested as a relatively simple, economical and fast way of separating and concentrating microbial cells from large volumes of aqueous food suspensions. Food matrix materials that may interfere with the rapid detection methods can be simultaneously eliminated so as to avoid false-negative results....   [tags: filter, pathogens, suspensions]

Solid And Liquid And Vapor

- Solid to liquid and liquid to vapor is the general idea many have of the transition of water from ice to gas. Water changes to these three phases because of the change in the amount of heat added, which leads to a change in the temperature and the pressure. Temperature is a measure of the average kinetic energy of the particle. As the temperature increases or decreases, it affects the movement of water molecules. Potential energy is the energy that has a constant temperature, but has an increase in heat....   [tags: Energy, Kinetic energy, Atom, Water]

The Effect Of Temperature On The Summer Winter And Winter

- As oil is evaporated, viscosity and oil density increases (Mishra and Kumar 2015) this can be seen from the values of viscosity for both the results for the summer and winter; the oil for the summer is more viscous than the crude weathered during the winter because of amount of volatile crude evaporated as seen in figures 15 and 25. Density for summer is less than the density for winter because more oil has been evaporated see figures 14 and 21. Dispersion of oil slick is dominant with high sea state conditions and low viscosity oils (Lehr 2001, Simecek-Beatty2010, Wang and Stout 2007)....   [tags: Water, Liquid, Petroleum, Oil spill]

Dielectric Properties Of Microwave Thermal Technology

- Introduction: Retorts, batch kettles, and aseptic processes are a few thermal techniques used within industrial food production. Overall, aseptic processing is a superior method for fluid systems[1]. Aseptic processing offers shorter processing times, higher production rates, and better product quality[1-3]. Within aseptic processing, there are several different forms of heat transfer, including direct, indirect, ohmic, and microwave heat exchange[4]. Microwave thermal technology offers more consistent temperature profiles across fluid systems because of dielectric properties of a fluid[5-11]....   [tags: Heat, Heat transfer, Energy, Liquid]

Replacing A Fractured Laptop Screen

- There a tremendous secret, or scheme some may say, that computer companies do not want to tell their customers when there is a need to replace a particular part for your personal laptop. The secret that major computer companies do not want to induce to the population is that they outrageously overcharge people to replace a fractured screen on a laptop that could be easily done by a non-professional. For instance, major companies like Dell and HP would approximately charge their customers between 100-300 dollars to simply replace a fracture laptop screen....   [tags: Laptop, Personal computer, Liquid crystal display]

Examination of the Densities of Different Liquids

- The purpose of this experiment is to examine the densities of different liquids, such as soft drinks and water. This experiment will help us answer the question, “which among these liquids has the greatest density?” The data collected from this experiment will be analyzed to compare the densities of these liquids. In using the Archimedes’ Principle, this experiment will seek to examine the density of liquids rather than solids. This experiment will explore the area of physical science and applying it to everyday objects....   [tags: density, archimede's principle, coke]

Solids, Liquids, and Gases

- Solids, liquids, and gases are the three main, or fundamental phases of matter. Each one has a different density and a different level of stability. What determines the stability of each phase is the bond between it's atoms. The tighter the bond between it's atoms the more stable that phase of matter is. Solids are the most stable form of matter, followed by liquids, and then gases. Solids have a definite shape and do not take the shape of their container. Liquids do not have any definite shape and do take the shape of their container, the same is true with gases....   [tags: essays research papers]

Research: Passing a Metal Ball Through Viscuous Liquids for Velocity Check

- Conclusion: To conclude, the hypothesis was proven right. Syrup, the most viscous liquid, caused the metal ball to have the slowest time. The strong frictional force that acted against the ball, caused the ball to have the slowest time. For example, water had the smallest frictional force which was 8.73 × 10-4 N, but syrup had a frictional force of 2.9x10-3 N and the time it took the ball to fall through the water was .16 s and for syrup was 5.03 s, which took longer than water .Therefore, the ideal frictional property that the U.S....   [tags: Science, Friction ]

How Boiling Is The Most Efficient Forms Of Heat

- Boiling is the most efficient forms of heat transfer since large values of heat flux can be realized at small value of temperature difference between a heated surface and working fluid. For conventional engineering applications the temperature difference is in the range of 5 ~ 15 K, which can cause heat flux values typically exceeding 10 W/cm2 (and in some reports reaching values as high as 1 kW/cm2). This is 100 ~ 1000 times higher than other forms of heat transfer (such as natural convection)....   [tags: Temperature, Thermodynamics, Heat transfer, Heat]

The Heat Of Gaseous Molecules

- Discussion At a constant temperature, a pure liquid has a vapor pressure that describes the pressure of escaped gaseous molecules that exist in equilibrium at the liquid’s surface. Adding energy to a pure liquid gives more molecules the kinetic energy to break the intermolecular forces maintaining the liquid and raises the overall temperature of the liquid. Eventually, adding energy boosts the liquid’s vapor pressure until it equals the surrounding atmospheric pressure. When this occurs, the pure liquid boils at a temperature called the boiling point....   [tags: Distillation, Temperature, Gas, Thermodynamics]

How pH Level Affects Corrosion Rate

- The purpose of this project was to discover how the pH level affects corrosion rate. The hypothesis was if the pH level affects the corrosion rate, then the lower the pH level is quicker the corrosion rate would be. This will happen because liquids below the pH level of 7 possess stronger acidic attributes. The effect of pH level on corrosion rate was determined by depositing a copper penny in each of three plastic cups, and then three different liquids by their pH levels, were assigned to be displaced into each cup formulating a chemical reaction to be observed....   [tags: science fair, hypothesis, scientific process]

Heat transfer of nanofluids in turbulent pipe flow

- Heat transfer of nanoparticle suspensions in turbulent pipe flow is studied theoretically. The main idea upon which this work is based is that nanofluids behave more like singlephase fluids than like conventional solidliquid mixtures. This assumption implies that all the convective heat transfer correlations available in the literature for single-phase flows can be extended to nanoparticle suspensions, provided that the thermophysical properties appearing in them are the nanofluid effective properties calculated at the reference temperature....   [tags: Technology, Nanofluids]
