 Think about your current home environment. If you used a manual wheelchair, would you still be able to live in your current home?

1.       Think about your own personal environmental hierarchical continuum. What are some of your proximal and distal environments? If you were suddenly unable to access these environments independently, how would this affect your life?

2.        Think about your current home environment. If you used a manual wheelchair, would you still be able to live in your current home? What new limitations would you face? What if you were using a power wheelchair or a scooter? What adaptations would have to be made? Would you be able to continue independently engaging in your meaningful occupations?

Does the patient require treatment prior to surgery and, if so, what treatment?

The patient's platelet count is normal, ruling out thrombocytopenia, and a single dose of ibuprofen would not be expected to result in a severe tissue hemorrhage, even with trauma. The PTT is prolonged, suggesting an abnormality of the “intrinsic” coagulation factors XI, IX, or VIII. Since this patient has no history of hemophilia A or B, a “mixing study” using aI: Idilution of patient plasma with pooled normal plasma to exclude an inhibitor is in order. A platelet function assay for von Wille brand disease is also indicated. The results in this patient are as follows: Inhibitor mixing assay – PTT (@ time 0) = 34 seconds (control = 32 seconds) PTT (@ 60 minutes) = 56 seconds (control = 34 seconds) Platelet function assay – PFA collagen/ADP….

What does immunopheno typing reveal

The PTT mixing study is consistent with an inhibitor, and the pattern of immediate correction followed by prolongation after incubation for 60 minutes is characteristic of a factor VIII inhibitor. PFA closure times rule out platelet dysfunction, either ibuprofen induced or von Wille brand disease. Further workup of the “inhibitor” requires measurements of factor levels and inhibitor titer. The results in this patient are as follows: Factor XI activity = 85% Factor IX activity = 91% Factor VIII activity = 2%; non-linear pattern with dilutions Factor VIII inhibitor titer = 23 Bethesda U/mL These results confirm a factor VI II deficiency-based coagulopathy consistent with an acquired “strong” autoantibody to factor VIII (a factor VI II of 2% with non-linear dilutions and a titer of 23 Bethesda U/mL). n….

How do you account for the fact that, although potassium is placed after argon in the periodic table

How do you account for the fact that, although potassium is placed after argon in the periodic table,

it has a lower relative atomic mass? What is the evidence that the aufbau principle is only approximately true? The first list in the table opposite contains symbols or phrases, each of which has a ‘partner’ in the second list. Match the ‘partners’; there is only one match for each pair of symbols or phrases.

Suggest explanations for the following. (a) High values of ionization energies are associated with the noble gases. (b) The enthalpy changes associated with the attachment of the first and second electrons to an O atom are exothermic and endothermic, respectively. (c) In an Li atom in its ground state, the outer electron occupies a 2s….

Draw possible stereoisomers for the trigonal bipyramidal [SiF3Me2]_ anion (Me ¼ CH3).

(a) Draw possible stereoisomers for the trigonal bipyramidal [SiF3Me2]_ anion (Me ¼ CH3). An

X-ray diffraction study of a salt of [SiF3Me2]. shows that two F atoms occupy axial sites. Suggest why this stereoisomer is preferred over the other possible structures that you have drawn.

(b) Account for the fact that members of the series of complexes [PtCl4]2, [PtCl3(PMe3)]–, [PtCl2(PMe3)2] and [PtCl(PMe3)3]þ do not possess the same number of stereoisomers.

Explain briefly how the technique can be used to distinguish anatase and rutile.

(a) What analytical method is routinely used to screen polymorphs of a compound? Explain briefly how the technique can be used to distinguish anatase and rutile.

(b) What are the coordination environments of each Ti (IV) centre and O2- ion in anatase?

(c) Use the unit cell in Fig. 6.30 to confirm the stoichiometry of the anatase phase.

(d) Anatase preferentially crystallizes under ambient conditions and transforms to rutile at higher temperatures. At the structural level, how do you envisage the phase change taking place?

 

Give examples of other metal ions transported by metallothioneins.   

Sources of Cd include welding emissions, electronic components and NiCd batteries. EU and US legislations are now in place to reduce our exposure to Cd. Once absorbed into the body, Cd is targeted by metallothioneins, cysteine, the tripeptide glutathione and the protein albumin (Fig. 29.32) and is transported in the blood to the liver. (a) What features are highlighted in ball-and stick representation in Fig. 29.32?

Suggest how they originate in terms of the amino acid residues present in the protein. (b) Why are metallothioneins, cysteine, glutathione and albumin suited to binding Cd2+? (c) Give examples of other metal ions transported by metallothioneins.

Identify the accounting concept that was violated in each of the following situations.

Identify the accounting concept that was violated in each of the following situations.   1. Astro Turf Company recognizes an expense, cost of goods sold, in the period the product is manufactured.   2. McCloud Drug Company owns a patent that it purchased three years ago for $2 million. The controller recently revalued the patent to its approximate market value of $8 million.   3. Philips Company pays the monthly mortgage on the home of its president Larry Crosswhite and charges the expenditure to miscellaneous expense.

What is the probability that pˆD − pˆE is greater than the value found in part (a)?

Researchers are studying two populations of sea turtles. In population D, 30 percent of the turtles have a shell length greater than 2 feet. In population E, 20 percent of the turtles have a shell length greater than 2 feet. From a random sample of 40 turtles selected from D, 15 had a shell length greater than 2 feet. From a random sample of 60 turtles selected from E, 11 had a shell length greater than 2 feet. Let pˆD represent the sample proportion for D, and let pˆE represent the sample proportion for E.    a) What is the value of the difference pˆD − pˆE? Show your work.    (b) What are the mean and standard deviation of the sampling distribution of the difference in sample proportions pˆD −pˆE? Show your work….

code a java program that accepts the ingredients for a recipe in cups and converts to ounces.

Hi, I have to code a java program that accepts the ingredients for a recipe in cups and converts to ounces.I started off coding but I got stuck. I need to know if I'm on the right track or not. import java.util.Scanner;public class Chp4_Project       {public static void main(String[] args){Scanner input = new Scanner(System.in);System.out.print(“Enter the first ingredient: “);String ingred1 = input.nextLine(); System.out.print(“Enter the second ingredient: “);String ingred2 = input.nextLine(); System.out.print(“Enter the third ingredient: “); String ingred3 = input.nextLine(); Our input is to name three ingredients and the number of cups for each.  And then the output should have two lines of : 1. The names of the ingredients in the following format. The items inside <> are variables. The recipe uses , , and 2. The total volume of all….
