A power press makes steel pressings. The energy required for each pressing is 5000J with each pressing taking 1s. The time taken to remove the pressing and get the material ready for the next pressing is 4s.If the press is operated by an electric motor which runs continuously with a flywheel used to supply the extra torque required for the pressing. Determine the power of the motor that is required, the energy that has to be supplied by the flywheel and the moment of inertia of the flywheel if it’s speed is not to drop by more than 30 RPM from a speed of 600 RPM.

Jerry is participating in a resistance training program. While he is warming up for his barbell chest press (standard bench press) exercise he starts to think about how he is able to raise the weight, 135lbs, from his chest to full arm extension and back to his chest (1 repetition). Further, he wonders what is different when he is lifting a heavier weight like 185lbs. In your own words, please answer Jerry’s curiosities from a physiologic perspective. Be as detailed as possible.

A drill press is purchased for $12,000. It is anticipated that its market value at the end of any year will be 18% less than its market value at the end of that year. In other words, its market value is reduced by 18% each year. The repair costs are covered by the warranty in Year 1. However, the repair cost in Year 2 is $500 and increases by $500 each year. This machining company has an MARR of 15%. State here on Blackboard the minimum EUAC (to the closest penny) of this drill press and its economic life (in years).

In which way(s) does urbanization increase genetic drift (select all that apply)?

Environmental changes leading to an increase in genome-wide mutation rates

New populations establishing themselves in the urban environment leading to a founder effect

High number of roads in urban environment, cutting habitats in smaller fragments

Novel selective pressures in the environment such as pollutants leading to bottlenecks

1. Look up “heat engines” on the Internet. There will be a lot of technical discussion meant for engineers. Can you find any novel heat engines? Look up “nitinol engine.” Can you find heat engines that claim to work on small temperature differences? Do they discuss the poor efficiency that you get with small temperature differences (from the efficiency equation)?

1.How do Biocontrol genes for plant transformation be a novel approach to forest plant disease control? Please give examples/studies

2. Please give examples/studies on the use of microbial consortia for enhancing biocontrol activity against forest plant pathogens

3. Please explain why the use of regulators for expression of biocontrol genes can promote the efficacy of biocontrols

The authors identify a number of IFNg-stimulated genes in their study. They identify 3 genes they suggest are novel because no one has previously shown that these genes have a role in viral control of (-)RNA viruses. Choose one of these genes, identify its function, and speculate as to how it may control viral replication.

Pick one of the prompts below for Les Liaisons Dangereuses and respond to it in a manner that invites plenty of discussion.

1. The book, intentionally or not, contains many more instructions on morals than even a purposely-intentioned treatise. What are some of these instructions?

2. Discuss the presence of any of these topics in the book: fashion, religion, music, power.

3. Is Les Liaisons Dangereuses a cautionary tale? Is the book saying “Do immoral things and you will be punished in this world”?

4. Based on your reading so far, do you think that Laclos believes in love?

5. Discuss the ways in which sex is looked upon by various characters in the novel. Is it an irresistible instinct? A crude pleasure? A means to power? A sin? A thrill that comes about from violating certain social expectations? Something good?

6. Pretend you’re sitting down for an intervention with Valmont. How would you formulate a philosophically sound explanation for why he should change his ways? This should be crafted like a letter, maybe from the perspective of one of the characters or an “invented” character that can fit into the plot of the novel.

For the coming year, Paladin Inc. anticipates fixed costs of $120,000, a unit variable cost of $60, and a unit selling price of $90. The maximum sales within the relevant range are $900,000.
(a) Construct a cost-volume-profit chart.
(b) Estimate the break-even sales (dollars) by using the cost-volume-profit chart constructed in part (a).
(c) What is the main advantage of presenting the cost-volume-profit analysis in graphic form rather than equation form?
