(American Chemical Society, 2017-09-20)An improved performance of the cold fiber solid phase micro extraction (CF-SPME) technique was accomplished with the use of the pressure balanced procedure. In order to obtain a pressure-balanced state during extraction ... -
Determining Longwave Radiative Properties Of Flat Shading Materials
(2008-08)Solar gain through fenestration has a significant impact on building peak load and annual energy consumption. Shading devices, attached to fenestration, offer a cost effective strategy in controlling solar gain. The ... -
Determining Off-Normal Solar Optical Properties of Drapery Fabrics
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)The determination of off-normal solar optical properties of drapery fabrics is particularly useful in modelling the effective solar optical properties of pleated drapery. Special sample holders were designed and fabricated ... -
Determining Off-Normal Solar Optical Properties of Insect Screens
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)Shading attachments may have a strong influence on solar gain. The determination of off-normal solar optical properties of individual layers of glazing/shading systems is required in order to estimate this solar gain, which ... -
Determining Off-Normal Solar Optical Properties of Roller Blinds
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)Solar gain through fenestration constitutes a significant portion of peak cooling load and annual energy consumption in buildings. As such, any reduction in solar gain translates into savings associated with the cost of ... -
Determining the causality between U.S. presidential prediction markets and global financial markets
(Wiley, 2020-08-14)Prediction markets trade securities with final prices contingent on the outcome of future events, for example, who will win the next political election. We show how the outcome of a United States presidential election, ... -
Developing approaches for linear mixed modeling in landscape genetics through landscape-directed dispersal simulations
(Wiley, 2017-06-01)Dispersal can impact population dynamics and geographic variation, and thus, genetic approaches that can establish which landscape factors influence population connectivity have ecological and evolutionary importance. Mixed ... -
Developing Composite Indicators for Agricultural Sustainability Assessment: Effect of Normalization and Aggregation Techniques
(MDPI, 2017-12-01)The assessment of the sustainability of agricultural systems is multidimensional in nature and requires holistic measures using indicators with different measurements and units reflecting social, economic, and environmental ... -
Development and characterization of a laminar aerosol flow tube
(AIP, 2006-03)We have developed a new laminar aerosol flow tube (AFT) to study transformations such as ice nucleation, deliquescence, and efflorescence in model atmospheric aerosols. The apparatus consists of four sections which can be ... -
Development and validation of a fully automated solid phase microextraction high throughput method for quantitative analysis of multiresidue veterinary drugs in chicken tissue
