Document Summary

Ivf is unnatural but that doesn"t mean we should reject it because everything in medicine is almost unnatural. Should be up to the couplet that separating reproduction and sex will have any harmful consequences to marriage. Better to exist with birth defect than not to exist, justifies too much (in cases where the child suffers every moment) Argues against social justice (better off to adopt than creating another child): rules are not imposed on fertile couples to have children, therefore unfair to refrain infertile couples from having children. Arbitrary distinctions on fertile and infertile couples: should treat them equally, does not view infertile couples should spend money on resources they see fit. ); argues against this view: women don"t give informed consent to have babies because of social pressure, but doesn"t follow that having the option of. Macrolevel concerns on broader views of woman in society etc (ex: whether.

It is currently popular for automobiles to use 10% ethanol / 90%gasoline mixtures (âgasoholâ) as fuel. According to popularconsensus the main benefit of gasohol use is that it âreduces ourdependence upon foreign oil.â We test this assertion by making someelementary calculations. Our analysis will unrealistically ignoreengine maintenance issues associated with older automobiles (suchas gasket and seal hardening), added fuel consumption necessary toproduce grain used as a feedstock in ethanol production,incremental food price increases associated with a reduction ingrain stocks, and many other effects. Gasohol use typically reducesaverage fuel economy by approximately 15% and effectively leavesfuel prices unchanged. This article further debates the wisdom ofethanol use and may be of interest outside the problems:

These concerns and problems have been strongly influenced byconversations with Dr. H.J. Harmon, of the OSU physicsdepartment.

2. Consider a 14.2 mpg 1991 Ford F150 driven 761 miles. Calculatethe pure gasoline consumption of this truck when: a) usinggasoline, and b) when using gasohol (with its attendant economyreduction). Determine the total CO2 emissions for each fuelassuming all fuels produce 20 lbs of CO2 per gallon. Comment uponthe wisdom of using gasohol versus pure gasoline in this vehicle.

A relatively new method of treating cancers is to bombard the tumorwith protons (The nuclei of hydrogen). The idea is that the protonswill eject electrons from the molecules of the cell, and thenelectrostatic forces (discussed in physics 1202W) will then pullthe molecule apart. If this happens in the cell DNA, the cell willbe sterile and thus will not reproduce but will disappear after itsnatural lifetime.

Electrons are however bound to their individual atoms, which meanthat relative to the world they have negative potential energy. Itis therefore necessary to transfer energy to them in order torelease them.

Consider the most favorable case. A proton collides head on with anelectron, so that after the collision, they both leave in the samedirection as the proton was incident.. The collision is elastic,i.e. no loss of energy, and the average binding (potential) energyof the electrons in the tumor cells is -5 electron volts.

What is the minimum energy of the incoming proton which will ejectan average electron? If instead of it being an elastic collision,the electron sticks to the proton to form a hydrogen atom, whatthen would be the minimum energy of the incoming proton?

( 1 electron volt = 6 x 10-18 Joules.

Mass of a proton 1..6 x 10- 27 Kg,

Mass of an electron 9.1 x 10-31 Kg).
