10min, the dosage of acid protease 3% (owf) and liquor ratio 1∶30. The result showed that the differences were very great in the whiteness, the grease content and the bacterial content of washed chicken feather fibers. Visual observation, infrared spectroscopy, optical microscopy and scanning electron microscopy were used to characterise the feathers and residues after extraction.The conclusion was that the effect of washed chicken feather fibers by biological method was superior to that of…

Witek-Krowiak et al., (2010) researched on the use of peanut shell to remove heavy metals from water solution. Cu (II) and Cr (III) ions were the heavy metals in this research, using Langmuir, Freundlich, Redlich–Peterson and Sips models to examine data gotten from the tests. The preparation of the bio sorbent material (peanut shell) was prepared by washing with pipe and refined water for about 1-2hrs to remove dirt and colour, the washed peanut shells were dried in an oven for a day then mashed…

core. An atmosphere is “layer of gases surrounding a planet or other material body, that is held in place by the gravity of that body. An atmosphere is more likely to be retained if its gravity is high and the atmosphere 's temperature is low”. Spectroscopy (along with atmospheric probes; Jupiter for example) has determined the Jovian planets contain hydrogen, helium, methane, ammonia, and water gas in their thick…

different motivation conditions (Sato, et al., 2012, p. 1). However, motivation and personality are not necessarily displayed outright. The authors’ tested the relationships through the NEO Personality Inventory-Revised and the multichannel near-infrared spectroscopy; the authors’ wanted to determine three motivations, which were control, monetary reward, and goal-oriented motivations (Sato, et al., 2012, p. 1). They wanted to use the motivations in order to determine if rewards had a…

The camera uses a blue light and orange filters to show discoloring below the skin's surface. Infrared photography is used to enhance difficult to see blood on dark and patterned clothing, and tattoos post-mortem difficult to see due to decomposition. Video Spectral Comparator, with this machine, scientists and investigators can see obscured or hidden…

Patients Choice Award and Compassionate Doctor Recognition award. Dr. Schmidt conducts research on diagnosis, treatment and risk factors. He breaks down clinical signs and symptoms and why compartment syndrome is hard to diagnose. He uses near-infrared spectroscopy and biomarkers. Dr. Schmidt also gives guidance on alternatives to…

The following analytical method is reported for the estimation of Atorvastatin. 1. UV Spectroscopy In the present investigation UV Spectrophotometer method was used for the estimation of Atorvastatin. Construction of calibration curve for Atorvastatin. Preparation of stock solution: Aqueous solutions of phosphate buffer of pH 6.8…

In this lab, benzoic acid, benzocaine, and 9-fulorenone are isolated from a three-component mixture by using the acid-base extraction and other following types of various extraction techniques. An acid-base reaction is utilized in order to isolate the individual species from the mixture. First, in isolating the base benzocaine, proton transfers occurred via reaction with hydrochloric acid, which led to a significant shift in the polarity of the said compound, although the conjugate acid of…

Melting point is the technique that disrupts the IMAF’s and forces the molecule to break by adding thermal energy to increase kinetic energy to the compound. When melting the unknown the interactions within the IMAF’s of the molecule are decreasing causing a disruption within the structure of the lattices. Determining the melting point of Unknown 105 A helps narrow down the possible compound that it can be, by the given melting point range. The narrower the range represents the relative purity…

Infrared Radiation (IR) Spectroscopy is a much stronger evidence in identifying and verifying the identity of the benzoic acid component. IR Spectroscopy can be used to differentiate the functional groups in compounds because different bonds absorb at slightly frequencies of IR radiation. In IR spectroscopy, the units of frequency is recorded as wave number. In benzoic acids, the functional groups present…
