555timer

Introduction
The 555 integrated circuit (chip) is used in a variety of timer and oscillator applications. A 555 timer is used to provide time delays and oscillations and as a flip-flop element. The device has additional terminals provided to trigger or resetting purpose (Nair, 2006). During the time delay operation mode, time is precisely controlled by an external resistor and capacitor. While working as an oscillator, the duty cycle and the frequency are accurately regulated by two external resistors and a capacitor (Brumbach, & Clade, 2003). 555 is triggered and reset on falling waveforms. A typical 555 timer IC is ...

The objective of this experiment was to prepare Beer-Lambert calibration curves for different forms of nitrogen and to determine the concentration of nitrate, nitrite, and ammonia ions in different water samples from the Biscayne Bay.

Introduction

Nitrogen is the most abundant element in the Earth atmosphere. In is not surprising that it is one of the most crucial elements not only to human life but all life on our planet. The chemistry of nitrogen is rather diverse because it can exist in different oxidation levels – from +3 to -5. Due to its large impact on the biosphere, the circulation of ...

Routing Information Protocol version 2 (RIP v2) is a routing algorithm that is based on the Bellman-Ford algorithm. As a routing algorithm, it is used to determine the best path between two nodes on a network using distance-vector for path estimation. It makes use of hop count, which is the number of intermediate routers and gateways between a source node and a destination node, to estimate the best path with the maximum hop count put at 15 (Kalamani et al., 2014). This ensures that there are no routing loops in the network. The Bellman-Ford algorithm is based on dynamic ...

A basic kinetic study of a chemical reaction often involves conducting the reaction at varying concentrations of reactants. In this way, you can determine the order of the reaction in each species, and determine a rate law expression. Once you select a reaction to examine, you must decide how to follow the reaction by measuring some parameter that changes regularly as time passes, such as temperature, pH, pressure, conductance, or absorbance of light. In this experiment we will use color change to derive the initial rates of the reaction. Before coming to lab you should read in your text the section on ...

Abstract

The objective of this laboratory experiment is to examine the qualities of projectile motion. Considering the movement of a steel ball in the horizontal plane, the initial velocity that is possessed by the steel ball can be ascertained from the assessed range. Considering the assumed initial velocity of the steel ball, the range of the projectile will be assessed for a variety of initial angles. The initial angles and will be computed by the application of the theory with regards to motion for constant acceleration.

THEORY

Considering a given initial speed demonstrated by v0→, with an initial velocity demonstrated by s0→ that is ...

Introduction

Of the over 6, species of anthozoans found worldwide, the northern Gulf of Mexico only has a few, Renilla mulleri is one of these. Commonly known as the “sea pansy” the Renilla mulleri is an anthozoan colony characterized by elongated white polyps that are vividly luminescent when handled in the dark. Under stimulus, these waves of luminescence move concentrically across the colony. Other characteristics include a short peduncle, which anchors to the substratum and makes distinct trails in the mud and the ability of the colony to use water to inflate itself.. It can be differentiated from the Renilla reniformis by ...
