Ethylene Gas Essay

are being grown in, with enough shade to protect fruit from scald, enough fruit to yield well, and some resistance to pests. Tomato Harvest occurs 75 to 80 days after transplant, although this varies by region and variety grown. For commercial processing tomatoes, a one-time machine harvest is used after the tomatoes are deemed ripe enough. Tomatoes, whether handpicked or commercially grown, are picked immature and then ripened later to prevent damage during shipping. Tomato ripeness is determined based on the color of the fruit. They are picked anywhere from mature green to the breaker (pink at the calyx end of the fruit) stage, depending on the operation. Tomatoes picked before mature green will not ripen properly with exposure to ethylene gas and would be considered unsaleable. Fruit should be waxy, free from damage (insect, hail, etc.), and have smooth, corky tissue at the stem scar. If the tomato is being picked one the vine, the vines should be free from damage as well. Fresh market tomatoes are hand-picked when they are ripe enough, often for a few weeks as tomatoes varieties generally ripen over a short period. Tomatoes are packed into polyethylene bins and then bulked into larger 1000 pound bins or directly picked into smaller boxes, depending on the operation and the stage that the tomato is at. Tomatoes are graded initially by the picker, avoiding damaged ones, or wet tomatoes. Wet tomatoes increase the amount of field heat given off from bins, causing quality…

The section has an examination of supporting evidence or contradicting conclusions, and suggestions for the further research. At the end of the discussion section, all the findings are joined together and summarized in a final statement. The Oracle paper has a complete analyzing of the evidence except for suggesting further research and possible contradicting conclusions. It seems that the purpose of this paper was to reinforce a previous claim about the Delphi oracle made prophecies after being…

It was my fourth attempt at making banana bread. The first attempt, it looked amazing, but crumbled into pieces as soon as I cut a slice. It was too dry because there was too much dry ingredients and less wet ingredients. The second attempt, it tasted like literal white bread. The texture was still dry but lacked sweetness because the bananas weren’t ripe enough and the sugar wasn’t enough. The third attempt, it looked like the flatbread sandwich from Panera. The sweetness was just right but…

M.Sc. Toxicology and Regulatory Affairs Case Report of Ethylene Glycol poisoning Anna-May O’Reilly 16205274 1.1 Case/Incident history A 67 year old man was brought to the local A&E department by his work colleague. The man had presented with ataxia, dizziness and vomiting and was severely hyperventilating. The pilots work colleague informed the staff at the A&E department that his friend is a retired pilot who runs flying lessons at the local airport. They are both…

change in permeant partial pressure across the film. Hence the permeability coefficient (P) is the proportionality constant between the flow of the penetrant gas per unit film area per unit time and the driving force (partial pressure difference) per unit film thickness. The amount of gas penetrating through the film is expressed in terms of either moles per unit time (flux) or weight or volume of the gas at STP. Commonly, it is expressed in terms of volume. The permeability coefficient (P), as…

If a collision is severe enough, a gas tank or a fuel line under the car hood may rupture. These kinds of incidents tend to be rare. However, there are a number of ways that a car fire can start that doesn't involve a car accident. Three of these are discussed below. Leaking Flammable Fluids Your car contains a number of flammable fluids. Gasoline is the most obvious and flammable of these. The most common reason for gasoline leaks is poor maintenance on the owner's part. Old fuel lines or a…

natural gas export, approximately 20% of natural gas produced in the U.S. in 2015. There are fifteen additional proposals being filed or in a pending status with FERC totaling a capacity of natural gas export of 25Bcf/d. The U.S. Energy Information Administration (EIA) studied the potential impact of increased exports in 2012. The case study indicated a potential 12Bcf/d of natural gas exports to increase domestic natural gas prices by $1.59/MMBtu. Clearly, gas is becoming the go to source…

Introduction: Photosynthesis is the process used by plants, algae and some bacteria, to use the energy from the sunlight to transform carbon dioxide and water into glucose and oxygen. The equation for photosynthesis is: carbon dioxide + water light energy glucose + oxygen. Chloroplasts are an organelle found in the leaves of green plants and are essential in photosynthesis as they are responsible for producing the glucose and storing the energy. Photosynthesis is vital for all life on…

Procedure: Before beginning each experiment, remove all clutter from the workstation and read the directions for the experiments thoroughly. Part 1: Warm slightly more than 300 mL of water to approximately 70 degrees Celsius. Measure out 150 mL of water into the coffee cup calorimeter. Take the temperature of this water in the coffee cup calorimeter once it has reached a steady temperature. Then, add an ice cube approximately the size of a large marshmallow. Stir the ice and water and measure…

steps that are critical to understanding the concept of equilibrium as a whole. First, an important concept to understand when describing any reaction is the idea of collision probability. When we examine gas molecules in a 1 cm3 container, there can be billions of collisions per second between neighboring molecules, and even then, maybe only one of these collisions result in a reaction. If any one collision occurs, the only way they will react to form a new molecule, in this case an HI…
