to observe the organelles of several classifications of cells including: check cells, onion cells and elodea cells. In Figure 1 an unstained check cells is shown clearly under a light microscope of a magnification of 100. According to Figure 1, the unstained check cell is not entirely visible under the microscope because no stains are used. Figure 1, shows some clusters of bubble-like structures, however can not be concluded that they’re check cells. Furthermore, the stained check cells in Figure

glass-reinforced epoxy on the orientation, morphology, and volume fraction of the fibers used in making the rod. This has been achieved by studying the surface of multiple cross-sections of the fishing rod that are mounted on epoxy by using optical microscopes. Then through analyzing different cross section, the mechanical properties of the studied fishing rod have been linked to orientation, size, shape, and volume fraction of the fibers. Introduction Composites, which are one of the primary branches

muscovite, smectite, kaolinite and nacrite (a typical hydrothermal mineral). Cross-polarized light shows that opal-CT has very low interference colours, in contrast to the brighter colours typical of chalcedony (Mustoe, 2008). However, polarizing microscope images alone cannot resolve the degree of crystallinity of phases. For this, XRD and Raman microscopy are required to clearly identify chalcedony, moganite, orthorhombic-silica, opal-CT, opal-C and quartz (Hatipoğlu and Türk, 2009). It is not easy

ATOMIC FORCE MICROSCOPY 1. Introduction to Atomic Force Microscopy An atomic force microscope (AFM) is a type of scanning probe microscope (SPM). An AFM uses a cantilever with a probe to scan over a sample’s surface. The probe is a sharp tip (3 to 6 m pyramid; 15 to 40 nm end radius) such as the one shown in Fig. 1. As the tip of the AFM approaches the surface, at close range, attractive forces between the sample surface and the tip of the AFM causes the cantilever to deflect towards the surface

Microscope While some looked to the cosmos, there were others more interested in the smallest details. The discovery of the microscope marked the beginning of modern biology, as this instrument helped boost biological studies and exposed the universe of tiny The Discourse on the Method It is considered as the important work of René Descartes, is a work that seeks to highlight the method to reach true knowledge and find the truth; It is a work that inaugurated modern philosophy. Among its benefits

number of methods were used to show this discovery. Embryos were analysed during a whole mount in situ hybridisation, and also by histological techniques (Nonaka & Tanaka, 1998). To view the nodal cilia, fluorescent microscopy using a confocal laser microscope, and immunoelectron microscopy using electron microscopy was used without electron staining (Nonaka & Tanaka, 1998). Electron microscopy was also used with electron staining to view the embryo (Nonaka & Tanaka, 1998). Fluorescent latex beads were

#2 Science Portfolio Reflection My Student Exploration packet of Cell Divisions, was the very first gizmo assignment handed to me by my science teacher, Mr. Moreno. I had recently been transferred to his class, so I didn’t understand what the rest of the class was doing. Fortionally, I used my quick thinking to boost myself up to the level everyone else was at. I read all three of the science books to understand the topics that they were studying. My former class were learning about outer space

1) Purpose: To learn how to use and analyze images under a compound light microscope. 2) Background Research: According to "The Microscope ." The Parts of a Microscope. N.p., n.d. Web. 20 Nov. 2015. , it gives the definition of different parts of a compound light microscope. According to the source it states,” The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to

Introduction: The Confocal Microscope is a type of microscope that is being developed for obtaining high-resolution images and 3D reconstruction. The images from the confocal are far better than other microscopes; however, not quite as good as fluorescent microscopes. Confocal microscopy has good impact values in visualizing the objects in life science; one of the top values is to show the fine image possible in 3D. Confocal microscopy has few advantages in different ways compare to Wide-field optical
