Integrated Assessment Of Novel Two-Season Production Systems In Mato Grosso, Brazil, Marcelo Moraes, Affonso Libera, Evgeny Latynskiy, Anna Hampf, José Maria Silveira, Thomas Berger 2017 Universität Hohenheim

Integrated Assessment Of Novel Two-Season Production Systems In Mato Grosso, Brazil, Marcelo Moraes, Affonso Libera, Evgeny Latynskiy, Anna Hampf, José Maria Silveira, Thomas Berger

Marcelo Carauta

One of the most significant advantages of growing crops in Mato Grosso (in mid-western Brazil) is that farmers can grow two crops (in some specific cases even three) in the same season. From an economic point of view, on the one hand, this provides a strong comparative advantage. On the other hand, this increases the number of decision variables that a decision making agent has to take into account. The agricultural production planning is complex and dynamic and it needs to consider crop rotation/succession in accordance with annual variability of climatic conditions. We developed a region-specific bio-economic micro-simulation model ...

The Construction IT Alliance (CitA) has been promoting the benefits of digitisation in the construction and engineering industry in Ireland since its formation back in 2002. Whilst the Alliance has always strived to ensure that its members are exposed to a wide spectrum of contemporary digital tools and processes, the concept of Building Information Modelling (BIM) has dominated the focus of its activities over the past five years.

BIM can be described as a digital tool that facilitates everybody to better understand a building or structure through the use of a digital model which draws on a range of data ...


Road Zipper™, Purdue ECT Team 2017 Construction Engineering & Management, Purdue University

Road Zipper™, Purdue Ect Team

ECT Fact Sheets

Construction work zones are growing in number around the world. The natural aging of existing roadway infrastructure ensures that more and more maintenance and rehabilitation will be required. Work zones, by their very definition, create two major problems that must be addressed in some way: safety and mobility. In the United States, highway work zones are responsible for almost 25% of all non-recurring congestion and 10% of overall congestion. Vehicle accidents are more common in work zones, and traffic congestion through work zones on urban arterials and freeways is often considered to be “unavoidable." To address these issues, ROAD ZIPPER ...


Microbial Repopulation Following In Situ Star Remediation, Gavin Overbeeke 2017 The University of Western Ontario

Microbial Repopulation Following In Situ Star Remediation, Gavin Overbeeke

Electronic Thesis and Dissertation Repository

In situ STAR (Self-sustaining Treatment for Active Remediation) is an emerging remediation technology which uses smouldering combustion to destroy nonaqueous phase liquid (NAPL) contamination in the subsurface. Since STAR smouldering travels through contaminated soils slowly (~0.5 to 5 m/day) and subjects them to high temperatures (400–1000°C), it is expected that this technology will thoroughly dry and sterilize the zones which it treats. Further, soils surrounding the treatment zone which are not smouldered will be heated, although not smouldered, by virtue of their proximity to STAR, impacting microbial communities within them. Therefore, the objectives of this work ...


The Irreversible Momentum Of Clean Energy, Barack Obama 2017 President of the United States

The Irreversible Momentum Of Clean Energy, Barack Obama

US Department of Energy Publications

The release of carbon dioxide (CO2) and other greenhouse gases (GHGs) due to human activity is increasing global av-erage surface air temperatures, disrupting weather patterns, and acidifying the ocean (1). Left unchecked, the continued growth of GHG emissions could cause global average tem-peratures to increase by another 4°C or more by 2100 and by 1.5 to 2 times as much in many midcontinent and far northern locations (1). Although our understanding of the impacts of climate change is increasingly and disturbingly clear, there is still debate about the proper course for U.S. policy—a debate that is ...


Moving Integrated Weed Management From Low Level To A Truly Integrated And Highly Specific Weed Management System Using Advanced Technologies, S. L. Young, S. K. Pitla, F. K. Van Evert, J. K. Schueller, F. J. Pierce 2017 Cornell University

Moving Integrated Weed Management From Low Level To A Truly Integrated And Highly Specific Weed Management System Using Advanced Technologies, S. L. Young, S. K. Pitla, F. K. Van Evert, J. K. Schueller, F. J. Pierce

Biological Systems Engineering: Papers and Publications

Integrated weed management (IWM) is one of the most commonly referred to approaches for sustainable and effective weed control in agriculture, yet it is not widely practiced, likely because current IWM systems fail to meet performance expectations of growers. The effectiveness and value of IWM systems should increase with increasing application specificity and true integration made possible with contemporary advances in technology, information systems and decision support. IWM systems can be classified based on their degree of application specificity and level of integration of tactics. In the application specificity pathway, a tactic is applied at a range of scales, from ...


Multiple Drivers Of Seasonal Change In Pri: Implications For Photosynthesis 2. Stand Level, Anatoly A. Gitelson, John A. Gamon, Alexei E. Solovchenko 2017 University of Nebraska-Lincoln

Multiple Drivers Of Seasonal Change In Pri: Implications For Photosynthesis 2. Stand Level, Anatoly A. Gitelson, John A. Gamon, Alexei E. Solovchenko

Biological Systems Engineering: Papers and Publications

The goal of this study was to explore the relationships between stand-level photochemical reflectance index (PRI) and canopy structure/ pigment pools, as well as light use efficiency (LUE) of photosynthetically active vegetation focusing on seasonal or ontogenetic time frames. PRI was originally designed as a means of assessing the xanthophyll cycle and LUE over short (e.g. diurnal) time frames, and few studies have explored the drivers of PRI over longer, seasonal time frames, particularly in crops having different photosynthetic pathways or canopy structures. Consequently, our purpose was to understand and quantify the drivers of PRI responses over seasonal time ...

Biological Systems Engineering: Papers and Publications

This study was conducted to measure the effects of swine slurry application method, time following slurry application, and runoff rate on selected water quality characteristics. Slurry from a commercial swine operation was broadcast or injected on field plots at a rate required to meet annual nitrogen requirements for corn. Rainfall simulation tests were conducted at five varying periods following slurry application. During each study period, three simulated rainfall events, separated by 24 h intervals, were applied for 30 min duration at an intensity of approximately 70 mm h-1. Following the third rainfall simulation event, inflow was applied at the ...


Multiple Drivers Of Seasonal Change In Pri: Implications For Photosynthesis 1. Leaf Level, Anatoly A. Gitelson, John A. Gamon, Alexei E. Solovchenko 2017 University of Nebraska - Lincoln

Multiple Drivers Of Seasonal Change In Pri: Implications For Photosynthesis 1. Leaf Level, Anatoly A. Gitelson, John A. Gamon, Alexei E. Solovchenko

Biological Systems Engineering: Papers and Publications

The goal of this study was to explore the relationships between the photochemical reflectance index (PRI) at the leaf level and pigment pools, focusing on the constitutive role of pigments in influencing PRI over seasonal or ontogenetic time frames. The purpose was to re-evaluate the role of PRI as an indicator of seasonally shifting pigment (chlorophyll, carotenoid and anthocyanin) contents, and hence photosynthetic activity, across a range of tree and crop species. We studied natural vegetation — three tree species (maple, chestnut and beech) and two managed irrigated and rain-fed crop species (maize and soybean), contrasting in photosynthetic pathway and leaf ...

Large Co2 And Ch4 Emissions From Polygonal Tundra During Spring Thaw In Northern Alaska, Naama Raz-Yaseef, Margaret S. Torn, Yuxin Wu, David P. Billesbach, Anna K. Liljedahl, Timothy J. Kneafsey, Vladimir E. Romanovsky, David R. Cook, Stan D. Wullschleger

Biological Systems Engineering: Papers and Publications

The few prethaw observations of tundra carbon fluxes suggest that there may be large spring releases, but little is known about the scale and underlying mechanisms of this phenomenon. To address these questions, we combined ecosystem eddy flux measurements from two towers near Barrow, Alaska, with mechanistic soil-core thawing experiment. During a 2 week period prior to snowmelt in 2014, large fluxes were measured, reducing net summer uptake of CO2 by 46% and adding 6% to cumulative CH4 emissions. Emission pulses were linked to unique rain-on-snow events enhancing soil cracking. Controlled laboratory experiment revealed that as surface ice ...


Lucidpipe™ Power System, Purdue ECT Team 2016 Construction Engineering & Management, Purdue University

Lucidpipe™ Power System, Purdue Ect Team

ECT Fact Sheets

In most gravity fed water transmission pipelines, it is desired to reduce excess pressure head to prevent undue strain on a pipeline and lower the incidence of leaks. Normally this is done with pressure reducing valves that essentially burn off this excess pressure as heat. The LucidPipe™ system converts it to low cost electricity thereby removing unwanted pressure and generating energy at the same time - energy that can be put used behind the grid or put back on the grid. The LucidPipe™ system extracts a small percentage of pressure head providing nearly invisible operation allowing water operators to fulfill their ...


In-Plane Loading Of Brick Veneer Over Wood Shear Walls, Elias Anis Toubia, James M. Lintz 2016 University of Dayton

In-Plane Loading Of Brick Veneer Over Wood Shear Walls, Elias Anis Toubia, James M. Lintz

Elias Toubia

In the design of wood stud walls with brick veneer, current design building codes specify that the wood stud wall should resist all in-plane and out-of-plane loads (IBC 2009). For out-of-plane loads, this assumption is entirely justified as the brittle brick veneer will crack and lose its capacity to resist bending. For in-plane loads, the brick veneer is significantly stiffer than the wood shear wall, and the veneer is unlikely to crack before the wood shear wall reaches its allowable capacity. The assumption that the wood shear wall resists the entire load is based on the further assumption that the ...


Evaluating The Suitability Of Microbial Induced Calcite Precipitation Technique For Stabilizing Expansive Soils, Sikha Neupane 2016 Boise State University

Evaluating The Suitability Of Microbial Induced Calcite Precipitation Technique For Stabilizing Expansive Soils, Sikha Neupane

Boise State University Theses and Dissertations

Expansive soils, also known as swell-shrink soils have been a problem for civil infrastructures including roads and foundations from ancient times. The use of chemical additives such as cement and lime to stabilize expansive soils is a common practice among geotechnical engineers especially for lightly loaded structures. However, several occurrences of subgrade failures were observed after stabilizing with chemical additives hence engineers are in search of sustainable stabilization alternatives. Microbial Induced Calcite Precipitation (MICP) is gaining attention as an environmental friendly soil improvement technique. Several researchers have successfully tested its feasibility in mitigating liquefaction induced problems in sandy soils. This ...

Automating Data Management And Sharing Within A Large-Scale, Heterogeneous Sensor Network, Jeffery S. Horsburgh, Amber Spackman Jones, Stephanie Reeder

Amber Jones

Hydrology researchers are collecting data using in situ sensors at high frequencies, for extended durations, and with spatial distributions that require infrastructure for data storage, management, and sharing. Managing streaming sensor data is challenging, especially in large networks with large numbers of sites and sensors. The availability and utility of these data in addressing scientific questions related to water availability, water quality, and natural disasters relies on effective cyberinfrastructure that facilitates transformation of raw sensor data into usable data product. It also depends on the ability of researchers to share and access the data in usable formats. In this paper ...

Time Series Analyst: Interactive Online Visualization Of Standards Based Environmental Time Series Data, Jeffery S. Horsburgh, Amber Spackman Jones, Maurier Ramírez, Juan Caraballo

Amber Jones

Visualization is a common need of many researchers, organizations, and projects that collect and use environmental sensor data. Web-based tools can provide screening-level visualization and data analysis functionality for users with a range of technical expertise. However, it is difficult to integrate data from multiple sources due to syntactic and semantic differences in data formats and different data delivery mechanisms that are not always interoperable. We developed an open-source time series visualization tool called the Time Series Analyst (TSA) that integrates data from multiple sources using web service interfaces and a standardized data encoding format. The TSA provides multiple types ...
