Assessing Carbon‐Based Materials Of Belo Horizonte Municipal Solid Waste Management, Maryegli Fuss, Witold-Roger Poganietz

Life Cycle Assessment and Other Assessment Tools for Waste Management and Resource Optimization

Municipal solid waste are mainly composed by carbon-based materials which leaves the households with still in-use lifespans. Many plastic bottles, papers, textiles, cans with tens of lifespan years are commonly found on streets, landfills, lakes, and oceans. A better use of waste products is demanding in a world of increasing competition for (mineral, metallic, and so on) materials and in some cases expected decline of reserves. Recycling is a source of much confusion particularly when comparing its process with manufacturing of new products. Notwithstanding, primary raw materials are became scarce. For this reason the increase demand for secondary raw materials …

Quantitative Risk Evaluation Of Obstacle Limitation Surfaces For Final Approaches At Airports, Amila Silva, Alexandre G. De Barros

Journal of Aviation Technology and Engineering

Obstacle limitation surfaces (OLS) are the main safeguard against objects that can pose a hazard to aircraft operations at and around airports. The standard dimensions of the most of those surfaces were estimated using the pilot’s experience at the time when they were included in the standard documents. As a result, some of these standards may have been overestimated, while others may not provide an adequate level of safety.

Examining Bus Lost Time Dynamics For A Bus Rapid Transit Station, Ankit Kathuria, M. Parida, Ch. Ravi Sekhar, Manu Pathak

Journal of Public Transportation

Bus Rapid Transit (BRT) systems are considered to be the most effective alternative for solving urban transportation problems for both developed and developing countries. The conventional approach to estimate dwell time (DT) is based on traditional DT models derived for normal bus stops, but not for modern BRT stations. BRT stations are different from bus stops in terms of length of platform, multiple loading areas, and number of passengers handled. Therefore, understanding dwell time dynamics, including the recently-introduced component of Bus Lost Time (BLT), is important to improve the operations of BRT systems. This research introduces various possible scenarios of …

Efficiency Of Chlorophyll In Gross Primary Productivity: A Proof Of Concept And Application In Crops, Anatoly A. Gitelson, Yi Peng, Andrés Viña, Timothy J. Arkebauer, James S. Schepers

Department of Agricultural and Biological Systems Engineering: Faculty Publications

One of the main factors affecting vegetation productivity is absorbed light, which is largely governed by chlorophyll. In this paper, we introduce the concept of chlorophyll efficiency, representing the amount of gross primary production per unit of canopy chlorophyll content (Chl) and incident PAR. We analyzed chlorophyll efficiency in two contrasting crops (soybean and maize). Given that they have different photosynthetic pathways (C3 vs. C4), leaf structures (dicot vs. monocot) and canopy architectures (a heliotrophic leaf angle distribution vs. a spherical leaf angle distribution), they cover a large spectrum of biophysical conditions. Our results show that chlorophyll efficiency in primary …

Do Natural Disasters Induce More Crime?, Michael Lentini, Plamen Nikolov, Matthew Schwartz

Binghamton University Undergraduate Journal

The Indian Ocean Tsunami of 2004 resulted in grave consequences for South East Asia. Indonesia, in particular, had the highest death toll, losing over 150,000 people. Indonesia’s coastal region Aceh was the hardest hit by this disaster. Exploiting exogenous spatial variation at the district level, we use difference-in-difference analysis to estimate the causal effect of the 2004 disaster on subsequent crime rates. We find that after the tsunami, total annual crime rate went down, on average, by 244 crimes per annum.
