shear mixing technology to create novel colloids. The dispersed-phase particles have a diameter of between approximately 5 and 200 nanometers.[2] Such particles are normally invisible in an optical microscope‚ though their presence can be confirmed with the use of an ultramicroscope or an electron microscope. Homogeneous mixtures with a dispersed phase in this size range may be called colloidal aerosols‚ colloidal emulsions‚ colloidal foams‚ colloidal dispersions‚ or hydrosols. The dispersed-phase particles

Title______________________________________________________________________ Influence of Rhizobium on the growth and yield of Rice Abstract___________________________________________________________________ Rice (Oryza sativa L.) is one of the world’s most important crops. The present investigation was designed to assess the range of growth-promoting activities of various diazotrophic bacteria on rice seedling vigor‚ its carryover effect on straw and grain yield‚ and the persistence of an

1. EGG INOCULATION The fertile hen’s egg can be used to cultivate and propagate various types of viruses. Because of the ability to alter their tropism and to adapt to a new host species‚ many viruses become capable of growing in chick embryo tissues wherein they frequently attain a much higher concentration than in the tissues of the natural host. STRUCTURE OF AN EGG The extra-embryonic membranes of the chick embryo arise from three germinal layers: the endoderm‚ mesoderm and ectoderm

A microscope (from the Ancient Greek: μικρός‚ mikrós‚ "small" and σκοπεῖν‚ skopeîn‚ "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy.Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes‚ the most common and first to be invented is theoptical microscope which uses light to image the sample. Other major types of microscopes

Introduction Using microscopes allows humans to see things they’ve otherwise would have never seen before‚ like cells. A cell is the basic unit of life. All living things are made of cells. All cells come from preexisting cells through a process called cellular division. There are two types of cells‚ eukaryotes and prokaryotes. Prokaryotes are very simple and small. They are unicellular and have no membrane bound organelles. Their DNA is found directly in the cytoplasm since they have no nucleus

Report Learning How to Use the Compound Light Microscope Introduction: Microscope is an instrument used to grow pictures of little questions that are difficult to see with the unaided eye. The compound light magnifying instrument‚ which will be utilized as a part of this lab movement‚ is an instrument with two focal points and different handles to center the picture. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: • Show the fitting methodology

The microscope is considered one of the most useful and important scientific inventions known to ’man’. The microscope was invented by Anton van Leeuwenhoek during the seventeenth century. Leeuwenhoek was not a scientist by profession. Initally he made a living selling clothes and buttons‚ but spent his spare time grinding lenses and constructing microscopes of remarkable quality‚ such as the light microscope. The light microscope could magnify cells‚ for instance in plants so you could see a clearer
