Part A- Additive Volumes First‚ obtain a dry 10 mL volumetric flask that includes a stopper with it and weight on a digital scale. Be sure to get the mass at the closest milligram. Then‚ pour DI water to the calibration mark of the flask. Place the stopper back and weigh it again on the same digital scale. Once recorded‚ it is okay to pour this water down the drain. Observations: Mass of Empty Flask Mass of DI Water Filled Flask 15.114 g 25.048 g Now‚ put 100 mL of ethanol in a beaker and

6. Results and Discussion 6.1. Mix Design of Cold Recycled Bituminous Mixture Compaction characteristics of untreated bitumen mixes according to Modified Proctor Test is shown in Figure 6. When the RAP content increased‚ it resulted in reduction of MDD and the corresponding increase in OMC. The decreased MDD is obtained due to the weak bond between RAP and the virgin material and also due to less fine material that plugs the voids to produce denser mix. The corresponding increase in OMC is

Atrazine (1-chloro-3-ethylamino-5-isopropylamino-2‚ 4‚ 6-triazine‚ CAS: 1912-24-9) was purchased from Dr. Ehrenstorfer GmbH (97.7%‚ Germany). Ethyl acetate (99.8%‚ ANPEL Scientific Instrument (Shanghai) Co.‚ Ltd.) was used as solvent for standard solutions. Acetonitrile used as HPLC eluent was purchased from ANPEL Scientific Instrument (Shanghai) Co.‚ Ltd.‚ KH2PO4·12H2O‚ K2HPO4·2H2O‚ dichloromethane and other chemical reagents used in cultivated media were purchased from Sinopharm Chemical Reagent

Liposomes of specific composition were prepared using a standard protocol. Briefly‚ Overnight hydration of lipid thin film obtained by high pressure vacuum evaporation of lipid mixture was done using Buffer A (Hepes-10 mM‚ KCL-150 mM‚ and 2mM EDTA‚ pH 7.4). This was followed by short periods of shaking and bath sonication for better retrieval of the lipids. Vesicles were generated from this initial mixture by freeze-thawing (10 cycles) and bath sonication for 20 min. 100 nm liposomes were produced

2.4.4. Toxicokinetics of MT: Both carbendazim and Methyl Thiophanate are classified as benzimidazole fungicides. Carbendazim is a major metabolite of benomyl with closely similar structural and toxicological characteristics. Methyl Thiophanate is also structurally related to both carbendazim and benomyl. Both benomyl and carbendazim are well absorbed after oral exposure (80–85%) but poorly absorbed after dermal exposure (1 or 2%) in rats‚ mice‚ dogs and hamsters. The major

Lab Report Macrocyclic Synthesis (Heme Analog) I. Purpose of Experiment and Introduction The purpose of this lab experiment is to prepare meso-tetraphenylporphin (TPP) and its copper‚ cobalt or zinc complex by condensing benzaldehyde with pyrrole in boiling propanoic acid. II. Introduction and Background There are two types of proteins that function as oxygen carriers: myoglobin (stores the oxygen) and hemoglobin (present in red blood cells and is responsible for oxygen transport)

A. The scientific principle behind step A is all to do with burning the seaweed and turning into ash. To do this it had to be done with a Bunsen burner which was on the blue flame so it was at its hottest to turn the seaweed into ash. B. In step B the scientific principle is the filtration of the purified water. The reason for the ash being boiled was to extract the iodine ions. D. The scientific principles behind step D was the adding of hydrogen peroxide solution to the remaining

The feed acidifiers market is flourishing due to the increasing use of feed acidifiers in treating animal diseases. The leading companies of the feed acidifiers market are continuously adopting new technologies and are using feed acidifiers for supplementing the diets of animals. The market value of propionic acid as a feed acidifier was the highest in 2012‚ and is projected to grow with the increasing demand for feed acidifiers in the livestock industry. The benefits of feed acidifiers are leading

Evidence Report The evidence contains ingredients B and E because when testing ingredient B during the heat test it burnt like the evidence. The evidence is like E because during the visual examination test I noticed they were both chunky‚ white powders. Also B and E are like evidence because during the Iodine test it didn’t turn purple or blackish so there was no starch‚ and Evidence is like E because there was bubbles during the vinegar test. That’s why I know that Miss Tavaglione’s Dr. Stench’s

Extraction and Evaporation: Separating the Components of "Panacetin" Submitted- July 17‚ 2012 Introduction The purpose of this lab is to investigate the composition of a compound suspected to be Panacetin‚ a type of pain-killer. Panacetin is typically made up of sucrose‚ aspirin‚ and acetaminophen‚ but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen‚ either acetanilide or phenacetin. Using techniques such as
