...A depression slide was obtained, and a small amount of petroleum jelly was smeared into the well. A living Daphnia magna was drawn up through the modified pipet and placed into the well of the depression slide. A KimWipe was used to absorb the excess culture fluid from the well, leaving the Daphnia magna hindered by the petroleum jelly and preventing excessive motion. Two drops of culture fluid were then used to cover the Daphnia magna to prevent dessication. The slide was then placed on the stage of a dissection microscope and left for one minute to give the Daphnia magna time to become calm. The heart of the Daphnia magna was then identified and observed. The number of heart beats in ten seconds was counted, and that number was multiplied by six to get the beats per minute for the room temperature reading at 23°C. A KimWipe was the used in order to remove the culture fluid from the...

...In 20-40% of acute pancreatitis patients biliary sludge is seen which is caused by biliary stasis. Factors that injure the pancreas cause the pancreatic enzymes normally activated in the intestines to now be activated within the pancreas. This is usually caused by one of two things: either a blockage to the pancreatic duct created by gallstones or a reflux of bile acids due to a weakened sphincter. Pancreatic necrosis can be the result of an obstruction to the pancreas. Trypsin, a protein-digesting enzyme, normally activated in the intestines, can become activated in the pancreas during acute pancreatitis. This can result in pancreatic hemorrhage and autodigestion. Few risk factors are associated with acute pancreatitis. Smoking, eating a diet high in fat, alcohol consumption, gallstones and genetic factors all increase the risk of falling victim to acute pancreatitis. (Lewis, 2014; Digestive Disorders Health Center,...

...magnified up to 300x and were free of distortion. Edward Jenner- Studied small pox. Came up with the first vaccine for smallpox. Alexander Fleming- Discovered lysozyme (an enzyme) was found in tears, saliva, and sweat could kill bacteria. What issues and types of instruments are involved in visualizing bacteria and viruses with a compound light microscope? Reflection- transmission-absorption with florescence-refraction. Condenser-is a lens that serves to concentrate light from the illumination source that is in turn focused through the object and magnified by the objective lens. iris diaphragm-regulates the amount of light on the specimen. objective lenses- magnifies ranges from 10x to 40x, ocular lenses. stage- supports the slide for viewing. focusing knobs-moves the stage up and down for focusing. total magnification- take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. What are the differences between a hanging drop slide vs a smear in examining a microbe? Hanging drop- often is used with dark-field illumination. A drop of culture is placed on a coverslip that is encircled with petroleum jelly. The coverslip and drop are then inverted over the well of a depression slide. The drop hangs from the coverslip, and the petroleum jelly forms a seal that prevents evaporation. This...

...T MAHENDRAN : QUALITY OF INSTANT GUAVA DRINK POWDER PHYSICO-CHEMICAL PROPERTIES AND SENSORY CHARACTERISTICS OF DEHYDRATED GUAVA CONCENTRATE: EFFECT OF DRYING METHOD AND MALTODEXTRIN CONCENTRATION T Mahendran Department of Agricultural Chemistry, Faculty of Agriculture, Eastern University of Sri Lanka, Chenkalady Accepted: 20th May 2010 ABSTRACT Dehydration of guava juice into powdered particles gives a considerable reduction in volume and is an effective method of prolonging the shelf life. Therefore, a research study was conducted to determine the effect of different drying methods and the addition of drying aids on the physico-chemical properties and sensory characteristics of dehydrated guava concentrate. Instant guava-drink-powder samples were obtained by dehydrating the concentrated guava juice using freeze drying, spray drying and tunnel drying techniques. Guava juice at 10.5°Brix was used to prepare the fruit powders. A significant reduction (p<0.05) in titratable acidity of 0.22% as citric acid and an increase in pH of 0.44 after drying of guava juice indicated that some acids were lost during the drying process. The oxidative loss of ascorbic acid was considerably lower in freeze drying (18.8%) compared to tunnel drying (32.2%). Spray dried powders were obtained from the guava juice with different maltodextrin concentrations as drying aids. When 30% maltodextrin was added to guava juice, the solubility of powder was 95% whereas, adding 60% maltodextrin decreased the...

...Unit 5: Anatomy and Physiology for Health and Social Care. Name: Fatimah Al_Asadi Teacher name: Miss Bull Name: Fatimah Al_Asadi Teacher name: Miss Bull Aim and purpose This unit aims to enable learners to understand aspects of the anatomy and physiology of human body systems. Learners will be able to gain an overview of the organisation of the human body before looking at how body systems work together to provide energy for the body. Learners will have the opportunity to investigate how homeostatic mechanisms operate in the body. Unit introduction This unit introduces core knowledge of cellular structure and function, and the organisation of the body as a whole, and then builds on this to develop a more detailed knowledge of the fine anatomy and physiology of the systems involved in energy metabolism. Learners will examine the homeostatic mechanisms involved in regulating these systems to maintain health. Learners will be given the opportunity to undertake practical activities which will require them to take measurements of the cardio-vascular system, the respiratory system and of body temperature, using noninvasive techniques to investigate normal responses to routine variations in body functioning. This unit provides the core understanding of human physiology that underpins the study of the specialist physiology units within this programme. The unit also provides an overview of body functioning that is valuable for anyone working or intending to work in a...

...ACCEPTABILITY OF AVOCADO AND YOUNG COCONUT MEAT AS HEALTHY SMOOTHIE Jo V. Ambat Annie Grace A. Bustamante Nico Braselle Casaña Raymond M. de Taza Manche P. Pere A research study presented to the faculty of Home Economics, Vocational and Technical, Education Department, College of Education, Cavite State University, Indang, Cavite in partial fulfilment of the requirements in HRML 24- Research I. Prepared under the supervision of Dr. Editha G. Reyes 1. INTRODUCTION The avocado is colloquially known as the Alligator Pear, reflecting its shape and the leather-like appearance of its skin. Avocado is derived from the Aztec word "ahuacatl". Avocados are the fruit from Persea americana, a tall evergreen tree that can grow up to 65 feet in height. Avocados vary in weight from 8 ounces to 3 pounds depending upon the variety. There are dozens of varieties of avocadoes. The rich and creamy Hass variety is the most popular type of avocado in the United States, and 95% of all avocados grown in the United States are produced in California, original home of the Hass variety. They are generally available throughout the year, they are the most abundant and at their best during the spring and summer in California and in October in Florida. While avocados are technically fruits, we have categorized them here as vegetables since this is how they are usually considered from a culinary perspective. Avocados can make a great base for a high-energy smoothie that will satisfy you and...
