Thanks for the reference. However, i am first looking for a second opinion, not beeing involved.

"Student100" you got it: "...broke his back..." As above explained from "ovacs", you need do have decelerating distance for the bullet to be stoped. Here is an example: bullet speed 500m/s and bullet weight 1gr and 2ms stopping time, then the resulting beat to person is 250kg, engough to kill...

Without weighing the adsorbed moisture, there can be no serious evaluation what happens. As you write, the surface area is important about the speed of adsorption as diffusion distance is short. But i can not give any clue about the influence of caramelization.

Lanolin and Energy Thanks for your contributions. Why have i come up with the question of propose of these lanolin molecules? There are some signs as energetic measurements, that these fat molecules may have photosynthetic features. Remember the day-night cycle of photosynthesis involving CO2...

Hello, Is there anywhere a reference to get an idea, why wool fat consists of over 200 different molecules? Is there some sort of a general law or ruling, like the Darwin's evolution, that nature produces nothing more and nothing less as what is required for the propose? If so, how is...

How were your tests arranged? But if you heat these sugars well above boiling temperature of water, there should be less water adsorbed, except you led both sugars cool down and give them time to adsorb water.

Look at the law of impulse Someone in the above replies talked about distance between the body and the outsite of the Kevlar vest. Remember there is the so called impulse, defined as the product of velocity and mass of the bullet, which is equal to the produced force by time during bullet...

Hello to all Experts in Adsorption Physics! Here is a research paper, stating that water adsorbed in a mineral called bentonite can store as much as 30 kJ/g. According our research and findings with such water based latent heat or phase change storage systems, there seem to be a fatal error...

Fatal Errors Thanks Mike to go down the hole so far. There is no need to push a sientific explanation about the measured figures we have observed. From an engineering point of view, we can work well with the results found. Compared to the potential competitor who also works with water and...

Thanks for your response. I may send a drawing about the set up of the experiment. But for now: It is always the same fat, which is on a substrat of saw dust. During a sunny day, the fat covered substrat is warmed up from the sun's radiation, which consiquently heats up the air passing the saw...

1) Same substance: animal fat consisting of hydroxy acids (C8-C41) and dihydroxy alcohols (C14-C36) 2) Same air for charging and discharging but higher % moisture for later as there is no sun heating. 3) There is no heat energy produced from PCM due to temperature difference but from phase...

PCM = phase change material

I fully agree with your explanations. What i am talking about is a latent heat storage, having an exceptional capacity of 1000kJ/kg of the storage material compared to about 300kJ/kg of ordinary PCM. Our PMC is charged with sun radiation and air passed through. It is discharged with moisture...

Serious: we work on a technical conception which applies sun radiation and air as in my introduction indicated. After unusal high heat rates measured, there was the guessing, if it could be a photosynthetic process developing that extra energy. However, we try to identify the cause of that magic...

Can this photo synthesis be done by technical means or is it only happen in plants? Synthesis: 6CO2 + 6H2O(gas) + sun radiation = C6 H12 O6(Glucose) + 6O2 Revers: (cellular respiration) C6 H12 O6(Glucose) + 6O2 = 6CO2 + 6H2O(gas) + caloric energy (deltaG) deltaG = -2880 kJ per mole...
