Introduction to Use of Silica in Sampling of Plant Compounds

Liquid chromatography is the most widely accepted and fundamental methodology for the separation and sampling of plant compounds. Liquid chromatography has the abilities to separate and sample a huge variety and diverse range of organic compounds ranging from proteins and peptides to small molecule protein drugs. The liquid chromatography is a technique that works by placing or injecting a minute volume of liquid sample into a silicon tube which is packed with porous substances or particles. This phase is called the stationary phase. The next phase is the extraction phase where the individual compounds present in the sample are transported over a packed tube ...

Part 1. Solar Panel History

The history of Solar panels takes it beginning from the 7th Century B.C. Now, the energy sector of economy has the greatest impact on our lives. Power supply is the basis of the normal functioning of any production, and, consequently, the entire human civilization. Heat and light homes, work machines and units in production, traffic and rural suffering - all these many faces of Energy. Various technological advances have already become part of life for us, but they are possible only when adequate and affordable energy supply, due to the development of alternative energy sources, ...

Introduction

Alternative renewable energy continues to grow popularity because of the upsetting climate change caused by greenhouse gases, exhaustion of non-renewable energy resources and rising global demand for energy. Renewable resources of electricity production are vital progress and are fundamentally motivated by cost.
Solar energy is clean and profuse that is why it is the best among the available substitutes. The modern solid-state photovoltaic (PV) technology began in 1954 upon the discovery of silicon (Si) diodes photovoltaic effect . Crystalline Si and a wide range of thin film solar cells, which are inorganic, are the prevailing photovoltaic technologies employed nowadays .

at Rex Hill Winery

Management of Rex Hill Winery has been highly concerned about climate change. They have heard about the Solar Sprint campaign to go solar now before the federal tax credit expires at the end of 2016. They also knew about the other incentives available on installation of solar electrical systems. Considering environmental benefits, they desired to install a PV solar panel system at their property. However, they wished to take a final decision on the project based on a feasibility study. As Rex Hill’s consultant, I have been entrusted the job of preparation of a ...

Use of Fossil Fuels for Power Generation and the Need for Renewable Energy

According to Nelson (2011), more than 85% of the world’s energy consumption, which is estimated at 520 exajoules, is generated through the burning of fossil fuels such as petroleum, natural gas and coal (p.19). Electric power generation from non-renewable sources will, unequivocally, result in their exhaustion and creation of a major energy crisis. For this reason, it appears primordial to shift in a greater scale to alternate power generation, such as solar, wind, hydroelectric, etc. Amongst these, Sorensen (2011) explains that though hydroelectric power does represent one of the major forms of power generation, its growth is stagnant ...

Solving Social Problems: Solar Energy in Rural India

The developing world grapples with the lack of access to electricity. Third world countries have poor electrical infrastructure which is still in the nascent stages of development. As a result, majority of people, especially those living in rural areas, have no access to electricity. The reach of the electrical grid in countries is limited to towns, and the poor who have access to electrical power supply suffer frequent and prolonged power blackouts. As a result, people in such countries result to unclean and unhealthy means of lighting, such as kerosene and diesel generators. The kerosene lamps cause respiratory problems ...

The Mobile Phone: Parts and Choice of Materials

The mobile phone is one of the greatest inventions of all time (Guthrie, 2008). It has revolutionized the way people communicate and perform their day to day activities. Cell phones allow remote communication with people in far-away places, including those in other continents. Initially, cell phones were only meant to people to call and send short messages in the form of SMSs. However, cell phones have now advanced and are being used for a wide variety of purposes including taking pictures and videos, listening to music, browsing the internet, playing games, organizing events amongst other uses. The functionalities that a phone ...

Introduction

The purpose of the experiment was to study Ohm’s law and to investigate the relationship between current and voltage in metal wire, lamp filament and diode.

Theory

Electric current (I) is defined as the rate at which charges flow through a conductor. Current flows when a conductor is connected to a power supply in a complete circuit. The battery provides the energy needed to move the charges through a conductor. The energy supplied by battery per unit charge is called voltage. Voltage is a measure of electrical potential difference between two points in a circuit. The potential difference between two terminals of a power supply is referred ...

INTRODUCTION

Baghouse filters are fabric filter units consisting of one or more isolated sections containing an array of fabric bags (Vatavuk, 1998). Shapes of these bags range from round, flat, tube-shaped, to pleated cartridges. In theory, gas containing high particulate matter level passes through the fabric bag surface. The particulate matter is retained while the cleaned gas is either recycled to the process or vented off the exhaust. This paper attempts to discuss the different concepts behind baghouse filters in relation to environmental engineering. Specifically, this paper discusses (a) particle pollution, (b) baghouse filter principle, (c) filter media selection, (d) types of ...

Lab Report: Common Emitter Amplifier

Introduction

A laboratory was conducted to evaluate the characteristics of a common emitter amplifier. The configuration is a bipolar-junction-transistor (BJT). Transistors allow current to flow from positive to negative states or from negative to positive states. A transistor board was supplied for the experiment. Five activities were done during the lab: a DC analysis, An AC analysis gain at midband (with bypass capacitor in circuit), AC analysis gain at midband (with no ...
