 | JMDMT #2406 Microfossils of Cyanobacteria in Carbonaceous Meteorites The James M. DuPont Meteorite Collection - chosen. Assuming full occupancy of all sites within the crystal structure, totally 39 different site occupancies reflecting the simplified empirical formula were modeled. These models allowed to both Ni and Fe atoms to be distributed over all three possible sites in various proportions. Then, step-scanned data were modified by subtracting of a constant at each step to lower background level to approximately 200 counts. This procedure significantly heightens R(sub)wp -factors that were used for selection of the most correct site occupancies. This set of diffraction data was processed by Rietveld code DBWS3,2S-PC-9005 [6]. After the final model of site occupancies was established, original data set was treated by DBWS9411 Rietveld program [7]. Turning-on sequence of refined parameters |
 | JMDMT #2403 Microfossils of Cyanobacteria in Carbonaceous Meteorites The James M. DuPont Meteorite Collection - Skala R.* Fryda J. Site Occupancies in Schreibersite from the Vicenice Iron: Rietveld Crystal Structure Refinement Meteoritic Fe Vicenice (classified as II D [1]) contains large skeletal schreibersite crystals [2]. Arithmetic mean of 41 analyses of these crystals performed on ED system (Link eXL) attached to SEM (CamScan) from polished and C-coated slice of the meteorite gave empirical formula (Fe2.21Ni0.77)(sub)Sigma = 2.98 P(sub)1.00 that was for further crystal structure analysis approximated as Fe2.2Ni0.8P. The only known crystal structure refinements of schreibersite crystal structure were performed by Doenitz in 1968 and 1970 [3,4]. The former paper suggested that Fe and Ni atoms are equally distributed between two of totally |
 | titin, the longest chemical ever hey guys this is just to show you how fucked up long a word can be in english, this is a thing called titin, its pretty much our "muscles" and its actually to long to put into this description, so just gonna put in some facts on it: btw, im not sure you can hear my voice: Titin is the largest known protein, consisting of 26,926 amino acids. The molecular weight of the mature protein is approximately 2,993,442.763 u[3], and it has a theoretical pI of 6.01[4] The protein's empirical chemical formula is C132983H211861N36149O40883S693. It has a theoretical instability index (II) of 39.69, indicating that it would be stable in a test tube. The protein's in vivo half-life, the time it takes for half of the amount of protein in a cell to disappear after its synthesis in the cell, is predicted to be approximately 30 hours (in mammalian reticulocytes).[5] |

 | Euclidean & Non-Euclidean Geometries Part 2 How geometrical ideas originally were fashioned (without deductive logic), what the Greeks did to formalize geometry, and what some of our basic concepts will be. (Definitions, axioms or postulates, logic, theorems. Do they yield reality?) The two parallelograms that I drew don't use the same lengths for a and b. I also use the word equation when I really wish I had said formula. Hey, someone could take apart practically every sentence I said, but I just hope they are there when I get to the conclusion of the series to help me defend the big surprise. Because the board isn't clear, let me summarize here: EGYPTIANS: Definitions + Inspiration or experimentation = formulae which describe part of reality pertaining to interesting spacial relationships. GREEKS: Definitions + Minimal axioms + logic = Theorems Theorems + more logic = More theorems and a many more aspects of spacial relationships than can be empirically derived. |
