Serial Port The microcontroller AT89C51 has an inbuilt UART for carrying out serial communication. The serial communication is done in the asynchronous mode. A serial port‚ like other PC ports‚ is a physical interface to establish data transfer between computer and an external hardware or device. This transfer‚ through serial port‚ takes place bit by bit. IBM introduced the DB-9 RS-232 version of serial I/O standard‚ which is most widely used in PCs and several devices. In RS232‚ high and

The latter involves serial dilution and spread plating of bacteria on agar plates. Materials required per pair • One 10 ml liquid culture of Escherichia coli BL21 (see prior preparation) • A sample of Yakult (approximately 5 ml) • Marker pens to label plates & bottles • Sterile plastic loops for streaking bacteria (up to 20 per pair) • Sterile plastic spreaders for spreading bacteria (4 per pair) • Sterile universals/bijoux bottles (8 per pair) for serial dilutions • 10 ml sterile phosphate

spectrum to determine the concentration of light absorbing molecules in a solution. (p.59) In this particular lab‚ our mission was to determine the protein concentration and the standard curve of the unknown sample of BSA. This‚ by preparing five dilutions of the unknown solution of BSA together with other known concentrations‚ and then experimenting by observing how the concentrations were passed through the spectrophotometer. The outcome resolved in the absorption levels being decreased‚ and this

growth of yeast is measured by using spectrophotometer and hemocytometer.We learnt how specthophotometer and hemocytometer use and also we learnt qualifications of hemocytometer and spectrophotometer.Serial dilution was used for this experiment and it was very important.Because of the serial dilution‚we measured the number of yeast cells. The graph of growth curve was drawn and bacterial life cycle was understood with the graph.The purpose of the experiment was to calculate and draw bacterial growth

experiment allowed the students to perform the plate count technique by serial dilution and two common methods‚ spread plate and pour plate to determine the colony forming unit (CFU) of yeasts A ten-fold dilution is used in this experiment‚ the sample is diluted until it reached the 10-9 dilution. Plating for spread plate started from 10-5‚ 10-6‚ 10-7 and 10-8 dilution while for pour plate‚ it started from 10-6‚ 10-7‚ 10-8 and 10-9 dilution. Having incubated inverted at room temperature (25oC) for 2 days

Serial murders are defined as a person killing three or more people in a period longer than a month. Most people are greatly influenced by their past. According to Scott‚ serial killers usually come from backgrounds of abuse (2014). This explains why serial killers are who they are.

The legal definition of insanity is based on the 19th century M’Naghten Rules: Does the offender understand
