  • Electric Fish Essay

    Many people may ask the question: why study such an exotic sensory system such as the electrosensation in electric fish? Could it be because of the natural curiosity that we as human’s exhibit, or maybe because we are intrigued by the various morphological and physiological adaptations that are seen across a plethora of environments? Well, more evolved organisms have achieved their higher traits not from new mechanisms that spontaneously appeared, but from old mechanisms that they share with simpler organisms. Therefore, it is through the study of simpler process that humans hope to better understand their own complex process. Electric fish have perfected the analysis of temporal information and have shown that they can very easily decipher temporal signal characteristics (Heiligenberg 1990). Better understanding how these incredible fish can so efficiently process temporal ques will give humans insight into how they can process temporal cues in something like speech perception (Heiligenberg 1990). In the fresh waters of South America, lives a type of weakly electric fish often referred to as the gymnotiform fish. These specialized animals are able to generate electrical fields via an electric organ that is located on their tales (Heiligenberg 1990). Electroreceptors that surround their bodies can not only detect their own electric field signature, but also the ones generated by other weakly electric fish in close proximity (Heiligenberg 1990). When the fish is near an…

  • Molecular Electrostatic Potential (MEP) Surface Of Pyrazolooxazines

    3.2. Molecular Electrostatic Potential (MEP) surface of Pyrazolooxazines. The correlation between the molecular structure and the physicochemical property of molecules, including biological molecules and MESP-based drugs, to distinguish electron rich zones (electrophilic attack) from electron-poor ones (a nucleophilic attack) 16, 17. We represent in this study the molecular surface of the electrostatic potential (MESP), the electrostatic potential (ESP) and the electron density (ED). MESP is a…

  • Phenomenon Of So Coulomb Experiment

    Indeed, electrostatic phenomena are the sights we see most of the day. Some of us may have fun to rub a plastic ruler on our hands and then bring it closer to our friend's hair until it appears that a few strands of hair stood up because of it. Or try using a balloon, rub it into our hair and then stick it on the wall, see what happens? The balloon will stick to the wall. Or on a large scale electrostatic phenomena that you often see in an emergency because of lightning static load static…

  • Pyrazolooxazine Synthesis Lab Report

    Abstract. The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…

  • Colloidal System Essay

    We cannot addresses directly sedimentation / floating problem by electrostatic and steric stabilization. Particle sedimentation occurs from different density of dispersed phase and the dispersion medium. Higher difference in densities faster the settling of particles. The gel network stabilization represents the principle to produce colloids are stable in both aggregation and sedimentation. Polymer is added to the colloidal suspension to form a gel network and it is characterized by shear…

  • Assess The Health And Safety Risks Essay

    the simplest things to do, but one of the most effective at the same time. Similarly with electrostatic discharge, the technician can use the ESD strap and mat to help prevent the smaller amounts of electricity from harming the user. Electrostatic discharge – This is a very common risk that occurs quite frequently when handling IT equipment. With all electrical equipment you touch and fiddle with, you are increasing the chance of experiencing electrostatic discharge. Metal conductors that get…

  • Static Electricity Research Paper

    Electrostatics is a big branch inside of the tree of physics. When studying electrostatics you will learn about electric chargers that do not move. Static electricity is one of the many things that are covered in electrostatics. An object that has accumulated electric charge has static electricity (“Electricity for kids”, 1). The charges are not on the move nor do they flow from one place to another. It is easy to remember that the charges don’t move in static electricity, because static can be…

  • Inductive Proximity Sensors

    • An oscillators. • A signal level detectors. • A solid-state output switching devices. • An adjustment potentiometers. Fig. 5.2 capacitive proximity sensor Capacitive proximity sensor are similar in size, shapes, and concepts to inductive proximity sensor. However unlike the inductive sensors which use induced magnetic fields to sense object, capacitive proximity generate to an electrostatic field and reacts to changes in the capacitance caused when a target enters the electrostatic…

  • Nuclear Radiation Essay

    Ionisation is when atoms turn into ions via radiation during this process the radiation causes the atoms to lose their electrons making the ions positively charged there are two types of ionisation Direct and Indirect. Direct ionisation can be caused by beta and alpha particles as they are both charged particles.due to this when either of these particles come near an atom the electrostatic force of the particle and if it is strong enough.The electron is pushed out of orbit around the atom…

  • Protein Structure Essay

    PROTEIN STRUCTURE Proteins are polymers which is set up by 19 different α-amino acids and one imino acid (Proline) linked by amida bond or peptide bond. A protein usually contain amino acid residues, covalently linked, which spontaneously form a three-dimensional structure, based on the self-recognition of its respective sequence. Covalent bonds (peptide and disulfide), hydrogen bonds, electrostatic interactions, hydrophobic interactions, and weak, nonspecific attractive and repulsive forces are…
