Effects of Pesticide Case Study INTRODUCTION The Bago City is the rice granary of Negros Occidental. The farmers of Bago City are struggling because of the pest. They have decreased their production of rice because of the pest. Our goal of engaging this case study is to analyze and see the effect of the pesticide to the crops. We are to seek good and bad effects of these pesticides. We’re going to focus only on finding the effects of these pesticides so we can come up with a good report. By observing

Modern-Surface Mining When coal seams are near the surface‚ it may be economical to extract the coal using open cut (also referred to as open cast‚ open pit‚ or strip) mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods‚ as more of the coal seams in the strata may be exploited. Large Open Cast mines can cover an area of many square kilometers and use very large pieces of equipment. This equipment can include the following: Draglines which

perpendicular to or normal to the section is called the normal stress. Normal stress may be tensile or compressive. Tensile stress: stresses that cause pulling on the surface of the section‚ (particles of the materials tend to pull apart causing extension in the direction of force) Compressive stress: stresses that cause pushing on the surface of the section‚ (particles of the materials tend to push together causing shortening in the direction of force) Strain • If a bar is subjected to a direct

energy that travel through the earth‚ and are a result of an earthquake‚ explosion‚ or a volcano that imparts low-frequency acoustic energy. There are two types of seismic waves‚ Body waves and surface waves. Body waves travel through the interior of the earth. Surface waves travel along the earth’s surface and through water. Seismic wave fields are measured by a seismograph‚ geophone‚ hydrophone or accelerometer. These are used to measure earthquakes. When measuring these earthquakes these

Low Stony Hill is also composed a variety of species of forbs. The soils at this site include Eckrant cobbly silty clay (EcB) soils ranging from shallow to very shallow; however‚ the soil is well drained with moderately slow permeability and rapid surface runoff with 1-3 percent slopes. Methods Soil characteristics‚ which affect infiltration rates and are crucial to understanding infiltration‚ include bulk density‚ vegetation‚ and microtopography. To assess and calculate these characteristics‚ 32 microplots

of the sphericity F s‚ which is independent of particle size. The sphericity of a particle is the ratio of the surface-volume ratio of a sphere with equal volume as the particle and the surface-volume ratio of the particle. For a spherical particle of diameter D p‚ F s =1; for a non-spherical particle‚ the sphericity is defined as Dp: equivalent diameter of particle Sp: surface area of one particle vp: volume of one particle The equivalent diameter is sometimes defined as the diameter of

osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important role

energetic eruption‚ affirming the nucleation-site theory. The surface of the mint Mentos is covered with many small holes that increase the surface area available for reaction (and thus the quantity of reagents exposed to each other at any given time)‚ thereby allowing CO2 bubbles to form with the rapidity and quantity necessary for the "jet"- or "geyser"-like nature of the effusion. Each Mentos candy has thousands of small pores on its surface which disrupt the polar attractions between water molecules

permeable barrier whose total surface area is important in regulating the substances that diffuse into or out of the cell. However‚ as a cell grows in size‚ its volume increases at a greater rate than its surface area. Consequently‚ the surface area of the growing cell soon becomes inefficient for effective diffusion throughout the cell. This relationship between surface area and the volume of a cell can be expressed as a ratio; and the need for an effectively large surface area to volume ratio is considered
