3.5 Kinetics of the Alkaline Hydrolysis of Crystal Violet in aqueous solution in the presence of a Cationic and an Anionic Surfactant. 3.5.1 THEORY The alkaline hydrolysis of crystal violet‚ a carbocationicdye(CV+) takes place according to CV+ + OH- ↔ CVOH Where CVOH is the colorless carbinol form of the dye. The kinetics of the reaction can be monitored due to the carbocation form of the dye by measuring the decrease in absorbance at the wavelength corresponding to the absorption maximum(λmax)

Pher Pher A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system‚ modeling its process aspects. Often they are a preliminary step used to create an overview of the system which can later be elaborated.[2] DFDs can also be used for the visualization of data processing (structured design). A DFD shows what kinds of data will be input to and output from the system‚ where the data will come from and go to‚ and where the data will be stored. It

CHAPTER 4 HARDWARE DESCRIPTION 4.0 Arduino: The Arduino Uno is a microcontroller based on the ATmega328. It has 14 digital input/output pins in which 6 can be used as PWM‚ 6 analog inputs‚ a 16 MHz ceramic resonator‚ a USB port‚ a power jack‚ an ICSP header‚ and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.[11] The Uno differs from all preceding boards in

How to draw a Pay Policy line? 1. Cluster Approach The simplest approach is to make a scatter diagram of the organization’s jobs‚ as is done in establishing the pay-policy line. When this is done it can often be observed that the jobs tend to cluster rather than scattering evenly. This effect can be taken advantage of by encasing the clusters horizontally and vertically‚ as illustrated in figure 1. This provides all three dimensions‚ but none of them is arrived at consistently‚ nor are they

In this article‚ DeLottinville charts the development of the late 19th century socio-economic struggles on Montreal`s waterfront‚ with a focus on the culture of labour forces. He argues that the culture developed under the dynamic leadership of Charles McKiernan‚ owner of a centrally located tavern and commonly known as Joe Beef. The article offers an outsider`s perception of his ideas of consensus as a progression towards the idea of collaboration thus creating a distorted view of the social structure

help of a doctor. Here‚ five little-known causes of sleep problems and what to do about them. 1. Light How it disrupts sleep: You probably already know that when you stay up late under bright lights‚ you interrupt your body’s natural sleep-wake cycle‚ because light tricks your brain into remaining in daylight mode. Less well known is that the light from computer screens and iPads shining directly into your eyes at close range is especially troublesome. Why? Part of the problem is that the light
