DAWN HELEOS-II light scattering detector (LS) and an Optilab-rEX refractive-index detector (RI, Wyatt Technology, Santa Barbara, CA, USA). The MALLS was equipped with a HeeNe laser set at 658nm. The mobile phase was a 0.1M NaNO3 solution that contained 0.02% Na3N at a flow rate of 0.5 ml/ min at 40 0C. The data was processed using Wyatt Astra software (Version 5.3.4.14, Wyatt Technology, USA). Neutral sugar composition The monosaccharide composition of pectin was established according to the method by Nagel et al., (Nagel et al. 2014) with some modification. Analysis was carried using HPAEC-ICS 3000 Dionex System (Thermo Fisher Scientific) with an AS50 Dionex auto sampler, a 3 × 30 mm CarboPac PA20 guard column, and a 3 × 150 mm CarboPac PA20 column was used (Thermo Fisher Scientific, UK) were connected in series, an ED fluorometer detector (Thermo Fisher Scientific,UK) was used to monitor the sugars. 10 mg sweet potato pectin was hydrolyzed with 4ml of 4M Trifluoroacetic acid (TFA) at 121ºC for 4hours, thereafter it was cooled down and TFA evaporated on a warm water bath while flushing with nitrogen gas till dry. The dry hydrolyzed samples were dissolved into ultrapure water to make 10ml volume, eventually the sample was diluted to 10ppm for injection in HPAEC. Eluent A was ultrapure water (0.055 μScm−1 at 25 °C); eluent B contained 170mM sodium acetate (NaOAc) in 0.1M NaOH, while eluent C consisted of 0.5M NaOH. Eluent B was prepared by dissolving NaOAc in ultrapure water…

Antwone Fisher is a 25-year-old African American man.

What is the percentage of change in Reaction Time as age increases? As people increase in age, their reaction time can change as well, either increasing or decreasing. If kids in different age groups measure their reaction time using a test online, then the percentage of change in reaction time will increase with age. There are an abounding amount of things that can affect how fast or slow someones reaction test time is, along with what happens to your body when it is measured and the process of…

The Great Bear Rainforest (GBRF) Negotiation began by allowing each stakeholder to outline their expectations and what was at stake. Furthermore, each group was given the opportunity to express their individual perspectives and the value of each factor. Negotiations began by discussing the immediate discrepancies amongst each stakeholders’ expectations, and seeking a resolution beneficial to each party involved. Overall, negotiations were relatively calm and level-headed, with the forestry…

Autocorrelation is not expected to be an issue with the model, given that the it is not using time series data, and it can therefore be assumed that there is no autocorrelation present in the model. To make sure that there is no perfect collinearity present in the model, it is recommended to run a collinearity test of the model (see: Exhibit 1.1). If a variable generate a VIF (Variance Inflation Factors) value above 10.0, the model might have a collinearity problem and attempts to correct the…

bat, “Savory Special” enabled him to recover from him fear and win the pennant for the Knights. In the novel, Bernard Malamud, based the series of events off the arthurian legends. The main character, Roy Hobbs is characterized as Sir Percival. His baseball bat named, Wonderboy, represents King Arthur’s sword, Excalibur.

In Getting to Yes by Roger Fisher, William Ury, and Bruce Patton point out that when negotiating, people have an inclination toward positional bargaining. When using this method in negotiations, people argue from their respective positions in favor of their desired outcomes, and the authors suggest that this method does little to reach ideal solutions, is inefficient, and puts relationships at risk. Throughout the book, they provide instructions for using the method they term “Principled…

Exercise 7 (set 1) 1. What are three versions of the null hypothesis? The three versions of the null hypothesis are: (1) “the observed difference was created by sampling error”, (2) “there is no true difference between the two groups” and (3) “the true difference between the two groups is zero.” (Barker, 56-57) 2. Is the null hypothesis typically stated in social scientific research? Why/why not? The null hypothesis is not usually stated in social scientific research. Researchers rarely state…
