After you have a chimney cleaner come out and clean away all the grime that build up in your chimney over the past year, you are also going to want to clean your fireplace as well. By cleaning your fireplace right after you have your chimney cleaned, your fireplace will be ready for next fall before summer even starts. Here is what you need to do in order to effectively clean your stone fireplace. Put On Protective Wear The first thing you are going to want to do is put on protective eye wear,…

Experiment 15.2 Purpose: To show temperature effects on reactions and Le Chatelier’s principle. Materials: 2 test tubes, 2 eyedroppers, 2 beakers, 2 small cups, Clear ammonia solution, White Vinegar, Flame or stove, Pot, Water, Ice, a few leaves of red cabbage, and safety goggles. Question: How does equilibrium work with respect to temperature and concentration? Hypothesis: Depending on whether the reaction is endo-thermic or exothermic the equilibrium will shift to one side, this is also true…

Experimental Design Aim 1: Determine the amino acid sensing specificity of folliculin. Since folliculin’s novel amino acid sensing function discovery, I plan to further understand whether FLCN specifically senses a certain amino acid and if this level of detection is enough to elicit an mTORC1 response. 1.1. Determine if folliculin’s novel molecular function in amino acid sensing is triggered by glutamine. mTORC1 activation by amino acids requires FLCN where its lysosomal residence during…

substance being in solution, it 'does not need to undergo dissolution.' (ref) As a result of this, the drug reaches its target much quicker and acts faster than it would if it were in solid dosage form. (5) Some drugs in solid dosage form can cause gastric irritation. However oral liquid formulations prevent this from…

as central nervous system stimulant (British Pharmacopoeia 2009). • Methyl paraben was generously donated by Arab Pharmaceutical Manufacturing Company. Methyl paraben is methyl-4-hydroxybenzoate, prepared by the esterification of p-hydroxybenzoic acid with methanol. It occurs as colorless crystals or a white crystalline powder. It is odorless or almost odorless and has a slight burning taste (Rowe et al., 2009). Methyl paraben is very slightly soluble in water, freely soluble in alcohol and…

a 25-mL round-bottomed flask along with a stir bar. To dissolve the camphene, 3.0 mL of glacial acetic acid was added into the flask. The flask was fastened onto a ring stand and immersed in a water bath that was on top of a stir plate. A thermometer wire was placed in the water bath to monitor the temperature throughout the experiment. After the camphene dissolved, 0.50 mL of 8 M sulfuric acid (H2SO4) was added. To prepare for heating, a cork was placed upside down to cap the mixture and…

9. RESULTS Table 8: Pre Formulation Study S.NO API CHARACTERISATION RESULTS 1 Physical Appearance a white to slightly pink crystalline powder 2 Melting point 138-148 ºC 3 Bulk density 0.396 gm/ml 4 Tapped Density 0.421 gm/ml 5 Carr’s index/Compressibility index 5.94 6 Hausner’s Ratio 1.063 Conclusion: The value of compressibility index above 25%, 15-25%, less than10% indicates poor flowability, optimum flowability and high flowability respectively. As Efaverinz value is <10 so it exhibits…

2.4 IL-DLLME procedures For IL-DLLME under optimum conditions, 10 mL of the sample solution containing Cd2+ or Ni2+ and PAN (10−5mol L−1) was adjusted to pH in a glass test tube with a conical bottom test tube. Using a microsyringe, the mixture of the extraction solvent ([Hmim][PF6]) and disperser solvent (acetonitrile) was rapidly injected into the previously mentioned aqueous sample. A cloudy solution (water, acetonitrile and [Hmim][PF6] ) was formed in the test tube. The ions reacted with…

A simple, economic, selective, precise, accurate and sensitive HPTLC method for analysis of Cilnidipine and Chlorthalidone, as a bulk drug and in formulation, was developed and validated according to ICH guidelines. The method employed HPTLC aluminium plates precoated with silica gel 60F-254 as the stationary phase while the solvent consisted of Toluene: Methanol: Ethyl acetate (8:2:0.1 v/v/v). The system was found to give compact spot for drug (Rf value of Cilnidipine and Chlorthalidone was…
