Zotero Tutorial - Automating References / Bibliography for Writing Research Paper, Book and PhD Thesis in MS Word. For academicians, researchers and Ph.D. scholars, inserting & editing the References or  Bibliography manually to a specific Journal Reference style is tedious & time consuming, while writing a research paper or a book or a PhD thesis or manuscripts with MS Word processor. With Zotero (freeware) in Word this boring and cumbersome referencing  process can be automated easily and quickly. This video tutorial demonstrates how to insert / modify the references fetched from webpages in word using Zotero.

Full width at half maximum (FWHM) for a curve is used in many scientific experimental data analyses. For instance, in X–ray diffraction analysis of crystal data, it is used to find the grain size from the curve. FWHM is the width of the curve or simply the difference in the corresponding two ‘x’ data values at y max /2. y max refers the highest value of ‘y’ or ‘y’ value for the maximum peak height.   Example Set of ‘x’ and ‘y’ data and the corresponding curve is given below: (View this Page for back reference.)     x      y 0.0    0.000 0.1    0.146 0.2    0.284 0.3    0.414 0.4    0.536 0.5    0.650 0.6    0.756 0.7    0.854 0.8    0.944 0.9    1.026 1.0    1.100 1.1    1.166 1.2    1.224 1.3    1.274 1.4    1.316 1.5    1.350 1.6    1.376 1.7    1.394 1.8    1.404 1.9    1.406 2.0    1.400 2.1    1.386 2.2    1.364 2.3    1.334 2.4    1.296 2.5    1.250 2.6    1.196 2.7    1.134 2.8    1.064 2.9

Assume a slice of pizza weighing 100 g has 250 Calories. Correlate its energy content to diesel (calorific value of diesel is 44000 kJ/kg; density of diesel is 0.83 kg L –1 ).   One dietary Calorie, C is equal to 1 kilocalories (kcal).   1 calorie = 4.184 Joules. 1 kg or 1000 g diesel has 44000 kJ = 44000/4.184 ≈ 10516 kcal.   In other words, 10516 kcal are present in 1000 g of diesel.   It is mentioned that, 100 g pizza = 250 kcal (or 250 C). Therefore, 250 kcal are present in (250×1000)/ 10516 = 23.8 g diesel.   Density of diesel = 0.83 kg L –1 = 830 g per 1000 mL.   This means, 830 g diesel occupies 1000 mL volume.    ∴ 23.8 g diesel = (23.8×1000)/830 ≈ 28.7 mL.   Hence, 100 g pizza with 250 Calories ≅ 28.7 mL of diesel.  

Blue Fishes There are 200 fishes in a pond. 99% fishes are blue. How many blue fishes should be removed to make the percentage of blue fishes in to 98%? Hint: 2 is not the answer. Answer First, why '2' is not the right answer? If you think 198 is the initial number of blue fishes and if 2 blue fishes are removed, then there will be 196 blue fishes and hence in terms of percentage it is 98. But its wrong, since the total fishes count also decreased to 198, if you just remove 2 blue fishes alone. So the percentage of blue fishes are (196/198) × 100 = 98.99% Its not 98% its almost 99%. In simple, 198 blue fishes and 2 other colored fishes are there initially. And if you remove 100 blue fishes, then 98 blue fishes with 2 other colored fishes. So, the percentage of blue fishes becomes 98. Answer: 100 blue fishes should be removed. Show the Answer Tennis Match Antony and Benjamin played tennis against each other. Its a bet game and

Designed a basic computer program “XRD CUBIC” (coded in Python)  to simulate possible unit crystal cell length (a), Miller indices - {h, k, l} and interplanar spacing (d) for cubic crystals from observed (experimental) X-ray diffraction (XRD) angle that is 2-theta.   It can simulate all these possible crystal lattice parameters for cubic crystal systems such as Simple Cubic or Face Centered Cubic or Body Centered Cubic systems, between the given 2–theta values within the range of specified cell length (a) limits.     1. Enter wavelength of X-ray (in Angstroms) 2. Enter minimum and maximum diffraction angle as 2-theta (in Degrees) 3. Enter minimum and maximum unit cell length (in Angstroms) All the possible cubic crystal parameters as well as diffraction angle with reference to d-spacing between the given Miller indices (h k l planes) will be simulated.
