Microwave

The changing in total energy refers to the fact that biochemical and physiological changes occurred during the time of different drying methods. The total energy of microwave drying was significantly higher than its counterpart sun and oven drying. It was also found that microwave drying resulted in higher amount of tannins than the sun drying whereas, oven drying exhibited the lowest value. There is no significant difference between the three drying methods for tannins…

Microwave meals save time in a pinch, but some families depend too much on them. In fact according to foodmatters.tv, “Today, over 90% of homes in America use microwave ovens for re-heating foods, and for daily meal preparations.” This overdependence on microwaves can create problems for the family. During meal times, families should sit together and discuss their day. However, microwave meals have destroyed this precious family time. Instead…

we flourish akin to a hardy plant. Furthermore, there have been instances found in the pages of history when a mistake(s) has led to innovation and invention. For instance, take into account Percy Spencer’s mistake and how it would lead to the microwave. Moreover, the article “In praise of careful science” states, “Denker describes how magnetrons and radars were discovered. They were researched for years. The work was kept secret. The scientists worked to avoid mistakes. When they were…

The sequence of the reactions employed for the construction of novel indole–benzimidazole-based 1,2,3-triazole hybrids is demonstrated in Scheme 1. Compound 2 was prepared by treating propargyl bromide with 1H-indole-3-carbaldehyde (1) in presence of potassium carbonate in dry acetone at reflux temperature [26]. Compound 2 was further reacted by heating at reflux temperature with o-phenylenediamine (OPDA) in chloroform for 6 h afforded compound 3. Compound 3 coupled with variously substituted…

new way to cook. The chocolate bar melting Percy's pocket that day lead to the invention of the microwave. One day at a Raytheon lab, Percy was standing near one of their experiments, the Magnetron. Standing near the Magnetron Percy noticed that the bar of chocolate in his pocket melted then Percy asked for popcorn kernels an put them near the Magnetron. We can now thank Percy Spencer for the microwave and for having popcorn.…

A base station for microwaves is line of sight (LOS) dependent and two stations can connect up to 48km if they are in LOS (Cowley, 2012). The further a microwave signal travels between relays the lower the possible data rate (Cowley, 2012). Microwave transmissions utilize an orthogonal frequency division multiplexing (OFDM) technique. The OFDM technique basically splits the high-speed…

Scientists discovered that there are microwaves coming from every direction in space. Electromagnetic radiation which was present shortly after the big bang is now observed as background microwave radiation. Big Bang theory says this energy has been travelling through space ever since it was created at the beginning of the universe, just after the Big Bang. CMBR Is the remains of energy created just after the Big Bang. Cosmic Microwave Background radiation supports the Big Bang Theory…

level one (100 W) for 30 seconds in the microwave. Coming out of the microwave they were about the same temperature and texture. For level 5 (500 W), the grass seeds were in the microwave for 30 seconds and were slightly warmer coming out of the microwave. Also the grass seeds felt very slightly moistened. After that, I did power level 9 (900 W) for thirty seconds. The grass seeds were noticeably warmer and slightly moist after coming out of the microwave. Next, I…

The generational divide is made evident in the chart found on wmfc.org as they define what each generation claims technology to be. The traditionalist were introduced to the Hoover Dam which was built during the Great Depression. According to the Hoover Dam Tour Company, the Hoover Dam was built because “People [wanted] to irrigate low lying plains, known as low desert areas, without suffering from flooding and the battle over water.” This project changed society and shifted the view on what can…

Discoveries have been made all around the world by many people for a long time. I believe that mistakes are a key part of discoveries. When Schliemann teamed up with Calvert to fund the dig, Schliemann had decided to do it his own way in which resulted with damage towards the artifacts of the city. They still found the city of Troy, but if Schliemann had not teamed up with Calvert would the lost city of Troy still be discovered without much damage to the ruins? Possibly, but back in 1871,…
