technology or political networks and 2) that the programming of single networks and switching of different networks are the fundamental sources of power. He even states that network programmers (media companies, public institutions, publishers, editors, technicians) and switchers –such as Rupert Murdoch who links media, cultural, political and financial networks- are the holders of power in the network society (p. 429). The example of Murdoch should not be misunderstood. According to Castells programmers

Ms. Precilla, Ms. Rajalakshmi, Ms. Saziana, Ms. Tan Lee Siew. Tutorial 7: Chapter 6 Reaction Kinetics & Chapter 7 Equilibria 1. Sulfuryl chloride, SO2Cl2, is a colorless, corrosive liquid whose vapor decomposes in a first-order reaction to sulfur dioxide and chlorine. SO2Cl2 (g) → SO2(g) + Cl2(g) At 200 °C, the half life of SO2Cl2 vapor is 3.00 × 103 seconds. Determine the rate constant for this reaction. 2. The gas phase decomposition of HI HI(g) → ½ H2(g) + ½ I2(g) has the rate equation as

Second Order Reaction Kinetics Abstract The objective of this experiment was to determine if the specific rate constant of the reduction reaction of hexacyanoferrate (III) ion with ascorbic acid (C6H8O6) is affected by the ionic strength of the solution and the charges of the ion species within the solution. A Cary Bio 50 Spectrophotometer and its associated software was used to measure the absorbance of the solution at a wavelength of 418 nm. Analysis of the data collected supports the conclusion

the Age of Modern Technology Families today live in a world saturated by media and technology. The average American child has 3.5 televisions, 3.3 radios, 2.9 VCR/DVD players, 2.1 video game consoles, 1.5 computers, and 3.6 CD or tape players in their home (Pigeron, 2009, p. 1). 84% of children ages 7-17 use the internet in their homes, and 57% have their own cell phones (Kennedy, Smith, Wells, & Wellman, 2008). Media has become intricately woven into the daily lives of families – it acts as

grow) as well as LB media. We also spent a majority of our time preparing for a PCR by mixing contents including: forward and reverse primers, template DNA, and Q5 Hot Start High-Fidelity 2X Master Mix (which contains a polymerase with 3’->5’ exonuclease activity, dNTPs, and Mg2+). Towards the conclusion of lab, the PCR tubes containing the contents necessary for a successful PCR were added to a thermocycler. The thermocycler’s role is to provide strict control over the reaction temperature and duration

As we look at the Chilean copper mine disaster in South America, knowing the audience will help the company communicate effectively between the workers needs, the needs of the entombed family members and the mass media. This information has to be told to each group in a different way. As we can all remember, a small copper mine in northern Chile suffered a cave-in on August 5, 2010, leaving 33 workers trapped underground at a depth of around 300 meters (Weik,

to one month. There has been controversy and stigma attached to the diagnosis of ASD since it was first added to the DSM-IV. This paper will illustrate the definition of ASD, the diagnostic guidelines, the difference between ASD and Acute Stress Reaction (ASR), symptoms and effective treatments, the impact of ASD and the coping skills needed to successfully get through it, and a biblical story and perspective about stress disorders. What is ASD and is it an appropriate response to trauma? Key

Identification of Chemotaxis Protein Substrates in Thiomicrospira crunogena Introduction Thiomicrospira crunogena is a Gram negative, aquatic, colorless sulfur oxidizing, chemolithoautotrophic bacterium. Cells are spiral shaped 0.2-0.3 µm in diameter and 1-2µm long, some individual cells can reach up to 30 µm long (3). T. crunogena is motile via a singular polar flagellum. It is the first deep-sea autotrophic hydrothermal vent bacterium to have its genome fully sequenced and annotated
