some study that like other plants lanzones peel has a certain compound that can repel mosquito. Way back in my elementary days I remember my sister making a project about this. They made a katol made from dried lanzones peeling they even copied the coil like structure of the commercially available katol. Here’s how they do it. Materials: Starch‚ aluminum foil‚ lazones peeling‚ commercial katol 1. Lanzones was sun dried for a few days. 2. If the lanzones is fully dried you can now pulverized it

THE PROBLEM: RATIONALE AND BACKGROUND A. Background of the Study The Antifungal Properties of Oregano Oil against Blastomyces dermatitidis Blastomyces dermatitidis is a type of pathogenic fungus which causes Blastomycosis‚ a yeast-likeyeastlike infection which occurs most frequently in dogs. It is seen most often in large breed male dogs‚ and especially in hunting dogs‚ sporting breeds‚ and dogs that spend a lot of time in environments where the Blastomyces organism exists‚ but female dogs

on each coil and one-half the circular-mil area of wire. In other words‚ if forty turns of No. 17 wire were used on the original motor‚ eighty turns of No. 20 should be used on the new motor. RECONNECTING THE POLYPHASE MOTOR FOR CHANGE IN SPEED It has been mentioned that the speed of a three-phase motor decreases if the number of poles is increased and vice versa. (A change in speed is also caused by a change in line frequency.) Most methods of changing speed involve rewinding the coils and altering

Transformer? A transformer is made from two coils‚ one on each side of a soft iron core. It can decrease the voltage (called a step down transformer). or increase the voltage (called a step up transformer‚ shown below). Alternating current is passed through the primary coil (the input) which creates a changing magnetic field in the iron core. The changing magnetic field then induces alternating current of the same frequency in the secondary coil (the output). A step up transformer has

antibacterial‚ antiviral‚ and antioxidant properties. There are many types of oregano herbs‚ and it is very important to use the best ones. The best herbs have the best chemical profile needed for the production of good quality oregano oil. Therefore‚ it is very important to be well aware of what product you are buying. Oreganol P73‚ by North American herb and spice‚ is made from the combination of high-grade wild oreganos‚ making it a potent supplement for the treatment of your cold. At the first

Design‚ Construction‚ and Testing of an Inductive Pulsed-Power Supply for a Small Railgun A. Sitzman‚ D. Surls‚ and J. Mallick Institute for Advanced Technology‚ The University of Texas at Austin Abstract—Advances in high-power-density batteries have rekindled interest in using inductive store as a pulse compression system. Although these batteries are considered very power dense‚ they lack over an order of magnitude of power density to drive a deployable electric gun. However‚ one can add

become corroded and brittle. There are many different parts to an ignition system. These parts differ between modern and old ignition systems. There is a coil. Sometimes one coil provides the increased voltage to the distributor or there is no distributor at all and each cylinder has its own coil to provide voltage for the spark plug. The coil is a compact‚ electrical transformer that boosts the battery ’s 12 volts to as high as 20‚000 volts. The incoming 12 volts of electricity pass through a primary

The designers use these factors to select a material and specify suitable values for the wire size‚ the number of turns‚ the coil diameter and the free length‚ type of ends and the spring rate needed to satisfy working force deflection requirements. The primary design constraints are that the wire size should be commercially available and that the stress at the solid length be

Permanent Magnet Moving Coil: Principle of Working When a current carrying conductor is placed in a magnetic field‚ it experiences a force and tends to move in the direction as per Fleming’s left hand rule. Fleming left hand rule: If the first and the second finger and the thumb of the left hand are held so that they are at right angle to each other‚ then the thumb shows the direction of the force on the conductor‚ the first finger points towards the direction of the magnetic field and the second

Suspend the spring from its support. 2. Hook the weight hanger from the bottom loop of the spring and determine the vertical scale reading of the bottom of the weight hanger. 3. Record this as the equilibrium position of the system. 4. Add 5 g to the weight hanger and again record the actual
