The evaluation of ceramic waste and hypo sludge for replacement of cement material begins with the concrete testing. Concrete contains cement, water, fine aggregate, coarse aggregate and grit With the control concrete, i.e 0%, 5%, 10%, 15% ,20% of the cement is replaced with ceramic waste & hypo sludge the data compared with data from a standard concrete without ceramic waste and HYPOSLUDGE individually. Three cube samples were cast on the mould of size 150 X 150 X 150 mm and…
How does the length of carbon chains, specifically those related to alkanols, namely ethanol 1- propanol and 1- butanol, affect the heat of combustion?
To investigate how the length of carbon chains affect the heat of combustion and enthalpy, in order to determine which fuel would be the safest and most efficient to take on a camping trip.
If the number of carbon atoms in an alkanol is increased, then the alkanol containing the longest carbon…
Periodontal disease is one of the most prevalent disease throughout the world (Albandar 2011). It is a chronic bacterial inflammatory infection leading to destruction of supporting tissues of teeth (Moffatt, Whitmore et al. 2011). It is second to dental caries as a cause of tooth loss among adults in developed countries (Gautam, Jindal et al. 2011), affecting 47.2% adults aged 30 years and older in the US (Eke, Dye et al. 2012).
Organisms causing periodontal diseases:
The boiling point of an organic compound determines its structural features and physical properties of the compound, which helps us to name the characteristics. Boiling point defined as the “temperature at which the vapour pressure of the liquid is the same as the pressure of the atmosphere on the liquid surface”. (Mahaffy, P, Bucat, B, Tasker, R, Kotz, J, Treichel, P, Weaver, G, McMurry, J 2011). The boiling point 1-hexanol, 2-hexanone, 1-pentanol and 3-methyl-1-butanol are represented in the…
• What is means of welding?
The welding is the processes which make the permanent bonding between the two or more solid bodies o the metal if the welding is not done properly the welding joint can be brake from the welding place and if the welding is done properly the metal can be brake from the middle or the center of the object
• Spot welding
There is many type of welding processes 1 Gas welding 2 Gas shielded arc welding 3…
Breathing is the body’s way of exchanging oxygen for carbon dioxide. The lungs get oxygen through alveoli. The air is transported though the trachea and diverted though the bronchi into a lung, the bronchi extends into smaller tubes called bronchioles witch at the end of them are little air sacks (the alveoli).
Oxygen is needed to get into the blood stream to allow oxygen to be supplied throughout the body in order for it to function normally. It does this by gaseous exchange.…
According to Hornbostel (1991), Beryllium is a hard, exceptionally, lightweight, gray-white metal, corrosion resistant at ordinary temperatures; chemically it is related to aluminum. Other than titanium, it is the only light metal which has both good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to…
You already know your pool has a pump, but do you really know what that pump actually does?
You might be surprised!
What Exactly Does a Pool Pump Do?
Your pool pump is the heart of your pool and without it, it would die...so to speak. Just like a human heart, your pool's heart (the pump) only has one thing it has to do which is pump water. However, that one thing serves several very important functions, such as:
• Pulls the water from your pool through the skimmers and drains.
• Then it…
Lab Question: Does the intensity of light affect the plant’s photosynthesis?
Background information: There are three main elements which has a huge impact on the plant’s photosynthesis: light, temperature, and carbon dioxide.(Plant and Light) However, this lab is focused on how the intensity of light affect the plant’s photosynthesis in order to see how the intensity of light affect the plant’s photosynthesis, specifically Elodea plants. Photosynthesis is a process which happens in all plants…
The reactivity of acid base cements forming hydroxyapatite (HA) such as, β-tricalcium phosphate (β-TCP) and dicalcium phosphate dehydrate (DCPD). Amorphous calcium phosphates, prepared by precipitation from supersaturated solutions, can also react to form apatitic cements since they are thermodynamic unstable with respect to HA and have a setting reaction more independent of particle size. Calcium phosphate cement containing an antibiotic can be used for filling bone defects and to…
