This study aims to know the active components of the materials for them to produce an alternative caramic product. This study will also compare the strength‚ texture‚ appearance‚ and water resistance of the experimental product and commercial product. Sawdust and charcoal ashes have an active component but it is just thrown away or ignored. So the present study is significant for the reason that it might produce

perceptions or view of the size of objects‚ are relatively constant despite the fact that the size of objects on the retina varies greatly depending on the distance; it is dependant upon three main depth factors being relative size‚ relative height and texture gradient. Relative size refers to the phenomena of an object becoming smaller on your retina when it is farther away from you; “the more distant an object‚ say a person‚ is the smaller the image of that object will be on your retina…” The second

There were portions of the movement in which the flute would play a melody above the rest of the instruments in homophonic texture. This gave the piece a light‚ fluttering sound. The second movement was an Andante. It started with the horn and flute playing with monophonic texture. This created a calm sound that brought

The questionnaire and constructed interviews were used to get the responses toward the color‚ appearance‚ aroma‚ taste and texture. Statistical tool used to evaluate the collected data are the weighted mean and frequency were further used to be able to come up with the results of the study regarding the perceptions on Ampalaya waffle.

There are two types of methods that can be used to determine fruit firmness i.e penetrometer and TAPlus Texture Analyser. The penetrometers are available with dial gauges calibrated in both metric (kg) and imperial (lbs) measurement and can be obtained to cover different ranges of pressure suitable for measuring either soft or harder types of fruit‚ depending

The Stanford Prison Experiment Psychological studies are relatively new as far as the history of scientific research is concerned. As with anything‚ the rules for these experiments have evolved and become what they are today only through past circumstances. There are some main experiments in past psychological history‚ which became a true turning point and reasons for ethical guidelines to be placed. These experiments include the medical atrocities during WWII‚ the Tuskegee syphilis project‚
