ww2 is the turning point for the US of A, for the worst.
it was the begining of the breakdown of american family traditions, the advent of negroids into the US military, and the cementing of banks and the fed supremacy uber all aspect of american economy amd lives.
it was the banks that pushed all these countries into war and on this v-day back in 1945, none of them,
NONE,
lost. they all won. -

2021-05-09 at 2:59 PM UTC in Asians are superior
Originally posted by Kev i dont know about that, she is demanding men white knight for them. modern women arent worth the cheese on my dick. let the rapefugees take care of them.
well i wouldnt call protecting women from sexual assaults 'white knighting'.
part of the blame lies in these western women, true. what do you think is going to happen if you go around dressed like a prostitute ?
but most of the blame lies in white, western men. none of this would happen had any of these white, western men have the courage to rape their womenvolk whenever they dressed like a prostitute to the point they stop dressing like one.
the purpose of blossoming flowers is to attract bees and the purpose of prostitutely dressed women is to attract dicks.
thats just how nature works. -

Summoning HTS to help answer the PRESSING QUESTIONS THAT WE ALL HAVE:
Highlight all that is true:
The TOF analysis instrument is:
1) stands for “time of flight”
2) requires a flight tube on the mass spectrometer
3) requires the equation KE=1/2mv2 for determining masses of molecules
4) measures absorbance
5) measures moving average
Examples of random is/are
1) noise caused by a cuvette
2) noise caused by a dirty mirror and lens in a spectrofluorometer
3) Johnson noise
4) Thermal noise
5) Shot noise
In an UV-Vis spectrophotometer equipped with a diode-array detector,
1) scans are performed one wavelength at a time, requiring greater than one minute to complete 200-800 nm scans
2) is equipped with a photomultiplier tube (PMT) for its detector
3) has the grating before the sample
4) has the grating after the sample
5) produced less noise compared to scanning spectrophotometer in our Lab exercise 1.
The following below results in absorbance in the visible region
1) protoporphyrin IX (PPIX)
2) 1,3-pentene
3) sigma to sigma* (sigma star) transitions
4) pi to pi* (pi star) transition
5) chlorophyll
The following is/are true of fluorescence
1) Compared to phosphorescence, it is a long lived emission
2) It is a cold-body emission
3) It involves an excited triplet state which is lower in energy than an excited singlet state
4) It is due to vibrational relaxation to the ground state
5) The fluorescence peak maximum occurs at a higher wavelength relative to the molecule’s absorbance peak
The excited triplet state of a molecule
a. has lower energy compared to the excited singlet state
b. is required for phosphorescence
c. is associated with parallel spin of electrons
d. results from electron spin inversion
e. results in diamagnetism
The following statements are true regarding liquid column chromatographyy.
f. the principle that makes separation work is that the analytes partitions between stationary phase and air phase
g. can be used to concentrate your analyte
h. the analyte moves down the column only when it is in the mobile phase
i. in order to achieve separation of four different compounds, all compounds must have the same partition coefficients
j. in order to achieve separation of four different compounds, each compound must have a different partition coefficient from others
Short/Long Answers
Fill in the blanks please.
The voltage across a 12 (ohm) resistor that is not connected to a power source will not be _______________
and can be described by the equation __________________. This noise is called ______________________.
The spectral output shown below is from _____________________ lamp.
This lamp would have to be combined with a __________________ lamp in order to provide an output from 200nm to 800 nm.
You wish to obtain the absorbance spectrum of a sample that is highly light sensitive, which means that light exposure to the sample results in its degradation. You need to obtain a spectrum from 200 nm to 800 nm. You have a choice between a diode-array, scanning spectrophotometers, and a scanning spectrofluorometer. Which instrument should you choose to obtain the spectrum? Why? You must answer the “why” to obtain full credit.
Your lab partner states that you should use the equation for root mean squared (rms) to measure the noise associated with the baseline spectrum below. Clearly state whether you agree or disagree by circling or highlighting the answer below, and then provide your justification. Failure to provide justification will result in no points.
Use RMS equation DO NOT use RMS equation
Why or why not
An organic molecule possesses two absorption bands (@ 230 and 390 nm), fluorescence bands @ 420 resulting from excitation of 390 nm band, and a phosphorescence band (@ 622nm). Some of these electronic transitions are depicted in the Jablonski’s diagram below. Complete the diagram by drawing the hypothetical absorbance bands, fluorescence bands, and the phosphorescence band on the plot below. Clearly label absorbance bands, fluorescence bands (emission) and phosphorescence band (emission). Denote the wavelengths of these processes by properly labeling the wavelength numbers where appropriate. Be sure to also note the following: Internal conversion, Intersystem crossing, singlet and triplet excited states, vibrational relaxation in the excited states.
A manufacturer of high-end UV-Vis spectrophotometer claims that their instrument produces only random noise in the UV region (250-300nm). You test this by taking 6 air measurements from 250 to 309 nm to determine if the noise is truly random. Based on the spectra provided, is the noise random? Circle the answer YES or NO below.
Also, in order to receive full credit, you must also justify your answer “Yes” or “No”. Use a moving average of 9 in your calculations. Use of any other number for your moving average will result in no credit.
Clearly label your columns and I need to be able to see the equations used.
Only circling the answer below will result in zero points.
YES NO
if your so smart then why are you carrying and wrapping furnitures.

Originally posted by Kev Iben Thranholm says Western men have been deprived of strength and confidence by feminism. All over Europe, white women of European ethnicity, French, German, Danish, Swedish are raped openly in public by the privileged people of color welcomed in by scum like Merkel, the corrupt French governments, the bought-and-paid-for Italians, the dumbshit British, and the white men just look away and walk on by. Not only has feminism deprived men of any sense of obligation to their women, they are scared to death of being arrested for offending a person of color by interfering with his rape of a white woman. Indeed, in Scandanavia women are not only afraid to leave their homes, they are afraid to report their rape, because the police might charge them with a hate crime for claiming rape by a protected person of color. In Sweden the protection of Swedish women is so nonexistent that it is becoming a right for a person of color to rape a Swedish woman.
LOL, FUCKING OWNED
the cunt made her bed let her fucking sleep in it, why would i have a sense of obligation to a sickening landwhale? justice is being served

its the same thing, albeit on a chinese scale. -
