Maintaining Harvest Fresh Apples Controlled Atmosphere Storage Requires Accurate Carbon Dioxide Measurements
Penny Hickey Application Engineer Vaisala Woburn, MA, USA Maintaining harvest fresh apples Controlled Atmosphere storage requires accurate carbon dioxide measurements Controlled atmosphere (CA) storage is a widely used technique for long-term storage of freshly picked fruits and vege- tables. Historically, CA storage has been the primary method for the long-term storage of apples. Through a biological process called respiration, apples take in oxygen and generate carbon dioxide, water, and heat. Controlled Atmosphere storage is an entirely natural process that reduces the effects of respiration to a minimum by controlling the environmental condi- tions surrounding the stored fruit. CA storage makes it possible to buy crisp, juicy apples year round. Many cultivars of apples can be preserved for a remarkable 9 – 12 months in CA storage, as opposed to only 2 – 3 months if using refrigerated storage. Optimal conditions important In order to effectively preserve apples the storage atmosphere must have a controlled amount of humidity, oxygen (O2), carbon dioxide (CO2) and temper- ature. The essence of CA storage is the range for O2 and CO2 concentrations, which both must be kept between 0.5 to 2.5%. The precise optimum concentra- tions vary for different varieties of apples (i.e. Golden Delicious apples may need different conditions than Jonagold apples, etc). The relative humidity is kept in the range between 90 to 95%. High relative humidity slows down water loss and enhances storage life of the produce, but humidity too close to saturation encour- ages bacterial growth. Temperature in the storage container is maintained 4 | Vaisala News 175 / 2 0 07 CA storage makes it possible to buy crisp, juicy apples year round.

SO I THINK ALL OF US ARE 16 CONCERNED ABOUT CLIMATE CHANGE FROM THE GLOBAL 17 IMPACT. WE'RE CONCERNED ABOUT WHAT'S GOING TO HAPPEN 18 IN AFRICA, WHAT'S GOING TO HAPPEN IN BANGLADESH; BUT, 19 ALSO, ALL OF US HAVE SOME INDIVIDUAL THINGS ABOUT 20 CLIMATE CHANGE THAT TEND TO AFFECT US. AND FOR US, 21 IT'S WHAT HAPPENS TO THE CORAL REEFS. AND WE SAW 22 SOME VERY GOOD PRESENTATIONS ON THAT YESTERDAY. 23 THIS IS A PICTURE I TOOK OF MY SON IN THE 24 CARIBBEAN. THIS IS ABOUT TWO YEARS, THREE YEARS AGO. 25 AND THESE ARE SOME PHOTOS IN THE CARIBBEAN THAT WE 0598 1 TOOK, SHOWING VERY LUSH CORAL REEFS, VERY 2 THRIVING CORAL REEFS.

INTEGRATING BIOPROCESSES INTO INDUSTRIAL COMPLEXES FOR SUSTAINABLE DEVELOPMENT A Dissertation Submitted to the Graduate Faculty of the Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Doctor of Philosophy in The Department of Chemical Engineering by Debalina Sengupta B.S., Jadavpur University (India), 2003 December, 2010 DEDICATION This work is dedicated to Objectivism ii ACKNOWLEDGEMENTS I would like to express my deepest gratitude to Dr. Ralph Pike for introducing me to "Sustainability", guiding me at every step and helping me in developing the intricate details of the concepts that formed this work. He is an excellent research supervisor, the best teacher, and above all, a compassionate and caring human being. From him, I have learnt that there is no short-cut path to achieving an “objective function”. I would like to thank my committee members, Dr. Carl F. Knopf, Dr. Jose Romagnoli, Dr. K.T. Valsaraj and Dr. Jonathan Dowling for helping us in evaluating the work with their valuable inputs. Tom Hertwig was an excellent person to work with as an industrial advisor. I remember the August afternoon in Louisiana's "Lower Mississippi River Corridor" when Tom showed me around the "Base Case of Plants". It was indeed a thrilling experience to put on the hard hat and boots and move around the Mosaic facility for acids and fertilizers production complex. I would like to thank all the members of the Total Cost Assessment Users' Group at the AIChE, and especially Lise Laurin for helping me understand the Total Cost Assessment Methodology.

From Food Waste to Biogas: Energy for Small Scale Farms an Interactive Qualifying Project Report
From Food Waste to Biogas: Energy for Small Scale Farms An Interactive Qualifying Project Report Submitted By: Natalie Marquardt Justin Marsh Joseph Pizzuto Alex Silk Sponsor: Nuestro Huerto Advisors: Prof. Robert Hersh Prof. Derren Rosbach This report represents the work of WPI undergraduate students submitted to the faculty as evidence of completion of a degree requirement. WPI routinely publishes these reports on its website without editorial or peer review. For more information about the projects program at WPI, please see http://www.wpi.edu/academics/ugradstudies/project-learning.html Abstract Our team faced the challenge of restarting and improving the design and operation of a small scale biodigester constructed by a WPI team the previous year for Nuestro Huerto, an urban farm in Worcester. The overall goal was to use the food and plant waste to produce a useable energy source in the form of methane gas and to serve as an educational example for the community. We developed methods to produce, filter, collect, and store biogas and used the gas as a cooking fuel instead of a heat source for the greenhouse. Our work was influenced by a human centered design framework in which we focused our design and improvements on the needs and capacities of our sponsor to maintain and operate the technology. I Acknowledgments The completion of this project and report would not have been possible without a few individuals who we would like to acknowledge. We would like to extend gratitude to our faculty advisors, Professor Robert Hersh and Professor Rosbach. They helped guide us through the project as well as draft and revise the final report for the project.

Pierson, Ph.D. NASA/Johnson Space Center 2101 NASA Parkway Houston, Texas 77058 281-483-7166 All substances are poisons: There is none which is not a poison. The right dose differentiates a poison and a remedy. Paracelsus (Philippus Aureolus Theophrastus Bombastus von Hohenheim, 1493-1541) INTRODUCTION TO TOXICOLOGY Toxicology dates to the very earliest history of humanity with various poisons and venom being recognized as a method of hunting or waging war with the earliest documentation in the Evers papyrus (circa 1500 BCE). The Greeks identified specific poisons such as hemlock, a method of state execution, and the Greek word toxos (arrow) became the root of our modern science. The first scientific approach to the understanding of poisons and toxicology was the work during the late middle ages of Paracelsus. He formulated what were then revolutionary views that a specific toxic agent or “toxicon” caused specific dose-related effects. His principles have established the basis of modern pharmacology and toxicology. In 1700, Bernardo Ramazzini published the book De Morbis Artificum Diatriba (The Diseases of Workers) describing specific illnesses associated with certain labor, particularly metal workers exposed to mercury, lead, arsenic, and rock dust. Modern toxicology dates from development of the modern industrial chemical processes, the earliest involving an analytical method for arsenic by Marsh in 1836.
