Mortar and pestle

To meet the ever increasing demands for improved quality of life, a number of pharmaceutical researchers have developed a variety of dosage forms and the oral route has always been the most preferred means of drug administration due to the ease, high patient compliance and low cost of production. In spite of a variety of dosage forms, tablets are most commonly adopted dosage form. The class II drugs have low solubility issues which results in poor dissolution rate and bioavailability[1,2].…

experiment’s aim is to measure the absorbance of lactase in different pH environments to determine which of the available pH solutions is the most optimal for the enzyme to catalyze in. To begin, we crushed a Lactaid pill, our source of enzyme, with a mortar & pestle and mixed thoroughly 4.0 mL a phosphate buffer, which is used to keep the pH constant, and filtered it through a tissue into a separate beaker to create a base enzyme solution. Next, we labeled each test tube 1-4 and created the…

portrayed through the whole idea surrounding Buddhism by its sacrifice rituals prescribed by the vedas through the rejection of authority,religious,or social, of the Brahmins.”So free am I,so gloriously free. Free from three petty things- From mortar,from pestle and from twisted lord,Freed from rebirth and death I am, And all that has held me down is hurled away” (Therigatha,121). This quote indicates that the speaker glorifies that Buddhism has set her free. The women are singing this to think…

Life during the Elizabethan Era was less sophisticated than today, and the life expectancy rates were low due to illness and malnutrition. For the upper class, with its more varied diet, life might be longer, but the poor suffered nutritionally due to money shortages. For these reasons, during the Elizabethan Era, food, nutrition, and accessibility were completely based on social class. Although food is for nutrition and diet, during the Elizabethan Era the rich ate out of luxury. For example…

The Snake River rises near the continental divide in Yellowstone National Park. The Snake River leaves Idaho through the Palisades Reservoir. When the Snake reaches Oregon it starts to flow north. This creates the border of Oregon and Idaho for 216 miles. The Snake River flows west and feeds into the Columbia River near Pasco, WA. Throughout the river there are steamboats going through the river, and railroads were built along the side. There is always a bunch of salmon coming through the Snake…

Page 455 There was a rumor about a plot to derail the soma yajna of Gautama. There was also apprehension that the offering in the yajna may not please Indra. Page 456 Gautama courted a great deal of pain for the success of this yajna. I also prayed Indra to fulfil Gautama's wishes. What about my wishes? I even didn't know what they were. I didn't worry about it, but for Gautama. I thought that our conjugal life would be wonderful if the soma yajna was successful. I would become normal and…

Objective The purpose of the experiment is to synthesize a compound with an organometallic iron-carbon bond and use infrared spectroscopy to investigate the unconventional sandwich structure. In addition, the experiment aims to understand pi-bonding of an arene ring, use cyclic voltammetry to understand the redox capacity of ferrocene, and explore the barriers between formal inorganic and organic chemistry definitions. Introduction Ferrocene was discovered unintentionally in 1949 when Miller…

Introduction In a marsh environment, it can be assumed by many that the studied environment exhibits a descending pattern as the land meets the ocean in a liminal boundary. This hypothetical descending pattern is both literal – an idea of where the elevation of the land decreases as the marsh reaches towards the marsh front, and figurative – that data taken from sample sites at the marsh such as pH, amount of organic matter deposited within the soil, and amounts of specific sediments deposited…

Introduction: Kidney stones, also known as renal lithiasis, are a common urinary tract disorder that often results from concentrated crystallized minerals in the urine. These minerals can include anything from calcium oxalate, calcium phosphate, to uric acid. Since the kidney stone has to travel through the urethra, it can be extremely painful depending on the size and shape. There are however many preventative actions to combat the formation of kidney stones. Most people have their own home…

The rising sun cast shadows on the newly blacktopped parking lot. On the outlying edges a fine mist rose from the morning dew dancing with the gentle breeze. It would have made for a breathtaking view had Georgette noticed it. However, this morning her eyes were watching her feet walk as her mind wrestled with reasons for the feeling of apprehension rising like a chokehold from deep within. Arriving at the back of Bus 57 she shook herself like a dog ridding itself of water. Her hand…
