In the most simple form‚ FM digital synthesis consists of two sine waves. One is called the modulating wave and the other is called the carrier wave. The carrier wave is the only waveform that is audible. The modulating wave does just as it sounds‚ it modulates the amplitude of the carrier wave‚ and acts as a control value. The frequency of the modulating frequency controls the rate of change in the carrier wave; it controls how fast the modulation occurs in the carrier wave. And the amplitude of

Gypsum Board (Drywall) Manufacturing and Recycling The Scale of the Trend and Green Strategies of Manufacturer University of Florida Abstract Drywall is a panel made of gypsum plaster which is pressed between two thick paper sheets. It is also known as gypsum board‚ plasterboard‚ wallboard and sheetrock. Its function is not restricted to interior walls only‚ it is also used in ceilings and partitions because it is a faster alternative compare to traditional plaster. 1 The largest gypsum

Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals‚ Figure 1. This spectrum was shown with different absorption bands corresponded with the functional groups of aspirin which was observed at frequencies > 1500 cm-1. These infrared frequencies were shown in Table 2. An infrared spectrum of an authentic aspirin was used to distinguish how authentic the infrared spectrum from the synthesis was shown in Figure 2 In this lab‚ aspirin was synthesized

(Robinson‚ 2011‚ p. 23). The origin of dreams encompasses three areas‚ the psychological‚ the scientific and the theoretical depending on to whom you talk. But for this paper‚ a review of Freud’s concepts of dreams‚ an analysis of the Activation Synthesis Theory of dreams‚ and an inquiry into the Activation-Information-Mode (AIM) Model of dreams will define dream theories. Dreaming is an important aspect of a person’s psychological well-being‚ and Sigmund Freud began the real inquiry into the process

Protein Synthesis Notes If DNA’s shape is altered it can’t function properly. RNA is more flexible so changing the shape changes the function‚ which is wanted. Any shape of RNA can become another. Three shapes/functions of RNA: -mRNA: messenger (linear_____) -rRNA: ribosomal (large and like a globe) More stable than mRNA. -tRNA: transfer (shaped like t) If you flatten this it becomes mRNA.

Recycling: make it the law? In 2013 we produced 254 million tons of waste. Of this 254 million tons: we recycled 34%‚ which isn’t a bad number. But of the rest of our waste that ends up in landfills: half could be recycled. That’s 84 million tons of waste that could be reused. So why are we just letting it get buried with the rest of our garbage? Recycling may be expensive and inconvenient in the beginning. But research shows the long term benefits of mandatory recycling programs. These benefits

Presidential elections have been going on in our county for hundreds of years. Most of them took place before television even existed. Television was invented witch color in the early 1960’s and that is when the first televised presidential debate took place (document D). Presidential debates‚ from the start have always been a pretty big hit on the television but ever since 1988‚ the debates ratings have been below 40. I think that this is because more interesting television programs have come

enetics is the study of heritable changes in gene function that do not involve changes in the DNA sequence. Involves a methylation composition that affects the communication and response between cells and DNA. We all know DNA is your genetic makeup passed down from generation to generation. However‚ our DNA is intertwined with a protein known as histone. The bond between histones and DNA can vary along the DNA strand. This is caused by mythol group composition that cause the histones and DNA to coil

Traditional way of synthesizing sensitive rhodamine starts with rhodamine B‚ amino compound‚ and some alkali additive in the presence of weak base. However‚ for RH-PY‚ the stearic hindrance of pyrene slows the reactivity‚ and the reaction does not go to completion. Therefore‚ the reaction procedure was modified as follows. First‚ HATU and DIPEA were used to activate the carboxyl group of rhodamine B‚ then the activated rhodamine B was reacted with 1-aminopyrene. By introducing this method‚ the reaction
