Influence Of The Moisture On Fumes Derived From The Anfo Detonation, Andrzej Biessikirski, Mateusz Pytlik, Michał Dworzak, Michał Twardosz, Mariusz Wądrzyk, Rafał Janus
Journal of Sustainable Mining
ANFO is one of the most commonly used explosives in open-pit mining, usually produced by mixing systems on the blast site. One of the problems usually not considered is the moisture”s influence on the stored ammonium nitrate(V). The influence of moisture on fumes and the detonation process has been investigated by placing ammonium nitrate(V) prills in the climatic chamber. In the investigation, the influence was evaluated for ANFO samples which were produced based on the two types of fuel oils. It was concluded that the 3.0% moisture level resulted in the lowest NOx content in both case studies. Further increased …

Vegetable raw materials, as an object of drying, are characterized by a large amount of water and a low content of dry substances. Vegetable raw materials have a capillary-porous structure. Food products contain both bound and free moisture at the same time. The removal of moisture from the material during drying depends on the total moisture content and the form of connection of moisture with the material. Adsorption and osmotic - bound moisture is retained at the interface of colloidal particles with the environment. Food products contain both bound and free moisture at the same time. The quantitative ratio between …

Exercise Science Faculty Publications
Urine osmolality is used throughout research to determine hydration levels. Prior studies have found black individuals to have elevated urine creatinine and osmolality, but it remains unclear which factors explain these findings. This cross-sectional, observational study sought to understand the relationship of self-reported race to urine creatinine and urine osmolality after accounting for age, socioeconomic status, and fluid intake. Data from 1,386 participants of the 2009–2012 National Health and Nutrition Examination Survey were utilized. Age, poverty-to-income ratio (PIR), urine flow rate (UFR), fluid intake, estimated lean body mass (LBM), urine creatinine, and urine osmolality were measured. In a sex-specific manner, …
Trends Of Autumn Phenology In Response To Environmental And Meteorological Variables, Meagan Renee Maguire
Trends Of Autumn Phenology In Response To Environmental And Meteorological Variables, Meagan Renee Maguire
Masters Theses
Previous studies have identified that changes in plant phenology are most likely induced by climate variability. One such change is the end of season (EOS) for deciduous forests in the United States. In essence, the EOS represents the end of plant productivity for a given year; the phase in which plant dormancy is reached. However, our wealth of knowledge on plant phenology largely overlooks the phases that occur in autumn, especially the EOS, with many previous studies focusing on spring phenology. This study uses remote sensing MODIS aerial imagery data and historical meteorological data to analyze any relationships that may …
Impact Of Dry Matter At Ensiling On Final Ph And Nutritive Value Of Mixed Cool-Season Haylage, Christopher D. Teutsch, A. E. Teutsch
Impact Of Dry Matter At Ensiling On Final Ph And Nutritive Value Of Mixed Cool-Season Haylage, Christopher D. Teutsch, A. E. Teutsch
IGC Proceedings (1997-2023)
Harvesting hay as baleage can allow for more timely harvest, especially in spring months when curing conditions are not ideal. Forage conserved as baleage undergoes anaerobic fermentation in which the sugars are converted to lactic acid, lowering final pH. To successfully conserve forage as dry hay, moisture concentrations must be less than 18%. In contrast, the ideal moisture concentration for baleage is between 55 and 65%. There are a number of producers harvesting and wrapping hay that is not quite “dry enough” to bale but is too dry to ensile. This produces a product commonly referred to by producers as …

IGC Proceedings (1997-2023)
Decreased fermentation and spoilage losses with improved aerobic stability during feed out can be accomplished by several strategies, such as wilting, addition of microbial additives and moisture absorbents. Particle size reduction may increase bulk density and improve the fermentation. The objective of this trial was to evaluate the effects of particle size, moisture content and a microbial additive on chemical-physical parameters and losses in silages made from Tanzania grass.

Inline Real Time Moisture Sensing For Gin Cotton, Lucas Gay
Theses and Dissertations
The objective of this study was to assess the performance of a capacitive sensor in measuring moisture content of cotton within the moisture range of 6-13%. The assessment was conducted in two phases: static and dynamic. During the static phase, models to predict moisture content were created and a 95% Confidence Interval of [-0.619,0.619], Percent Residual Accuracy of 97.586%, and a mean error of 4.396% were achieved. The Bland-Altman plot yielded a curve with a slight positive trend, suggesting the data could be modeled more appropriately by multiple models. The dynamic phase saw similar results as the static tests in …

Based on the three-step hybrid strategy of effective variable selection (rough selection, fine selection and optimal selection) in multivariate calibration of spectra, a feature variable selection method combining interval partial least squares (iPLS), interval variable iterative space shrinkage approach (iVISSA) and iteratively retaining informative variables (IRIV) was proposed to select the feature wavelengths of the near-infrared spectra of fresh chicken breast,and established a chicken moisture detection model. The number of modeled wavelengths was reduced by 0.76% after iPLS-iVISSA-IRIV, but the accuracy were stability of the model are gradually improved. The modeling results using the selected 8 characteristic wavelengths were as …

Synthetic Aperture Radar Observations At Salar De Pajonales, Chile, Michael A. A. Mcinenly
Synthetic Aperture Radar Observations At Salar De Pajonales, Chile, Michael A. A. Mcinenly
Graduate Student Theses, Dissertations, & Professional Papers
Remotely sensed microwave radars provide the spatial and temporal coverage needed to improve our understanding of the relationship between moisture content and salt pan mineralogy and, ultimately, climate variability. Moisture content in the surface and near-surface crusts found in salt pan environments, such as salt pan, has a significant impact on the backscatter values recorded by synthetic aperture radar (SAR) systems. This is because moisture affects the dielectric constant and surface roughness of the saline surface, which in turn influences the amount of electromagnetic energy reflected back to the SAR sensor. Changes in backscatter values are attributed to seasonal and …

Differing Moisture Content In Concrete And Mitigation Methods: Research Of Sacramento, Taylor S. Tonda
Construction Management
The city of Sacramento and its concrete foundations face one of the most challenging conditions in the flooring industry, high RH Moisture. RH Moisture or Relative Humidity Moisture is one of the main causes for flooring systems to fail. The source of High RH Moisture consists of surrounding geographic features like rivers, flood plains, and elevation, as well as improper or nonexistent use of a vapor barrier beneath the concrete foundation. Mapping and other data is used to support these claims. If a flooring system is not properly prepared for high RH Moisture levels, issues such as bubbling, delamination, and …
Soil Moisture Mediated Behavioral And Physiological Alterations Of Coptotermes Formosanus And Reticulitermes Flavipes (Blattodea: Rhinotermitidae), Steven J. Richardson
Soil Moisture Mediated Behavioral And Physiological Alterations Of Coptotermes Formosanus And Reticulitermes Flavipes (Blattodea: Rhinotermitidae), Steven J. Richardson
LSU Master's Theses
Substrate moisture is a critical environmental factor for the survival and behavior of subterranean termites (Blattodea: Rhinotermitidae). The invasive Formosan subterranean termite (Coptotermes formosanus) and the native eastern subterranean termite (Reticulitermes flavipes) co-occur in the southeastern United States, but C. formosanus is predominant in subtropical and R. flavipes is more common in temperate regions. The difference in their geographic distributions is largely attributed to their different behavioral and physiological ecology. While ample research has been done on foraging behavior of the two species, there was no empirical evidence for the effects of constant soil moisture on …
A Numerical Investigation Of Tornado Production And Intensification In Tropical Cyclones, Marco Paredes
A Numerical Investigation Of Tornado Production And Intensification In Tropical Cyclones, Marco Paredes
FIU Electronic Theses and Dissertations
The environmental conditions required for tornado formation and development in tropical cyclones (TCs) and the mechanisms underlying the intensification of TC tornadoes remain poorly understood. Previous research has suggested that low and mid-level dry air intrusion in TCs may enhance convective instability and influence the production of tornadoes. However, observations have their limitations in answering some of the key questions regarding the relationship among thermodynamic instability, dry air, and TC tornado genesis, development, and dissipation. In this study, a multiple nested Weather Research and Forecasting (WRF) model in a hindcasting mode is used to simulate Hurricane Ivan (2004) by resolving …

Biology Faculty Publications and Presentations
Cover crops are a sustainable management tool for mediating weed pressure, reducing soil erosion, and enhancing soil organic carbon (C) and nitrogen (N) levels. Yet, adoption rates across water-limited farms in Texas remain low, especially among producers without irrigation access, due to concerns that cover crop use of soil moisture will negatively impact subsequent cash crop yields. This three-year cover crop trial in a rain-fed sorghum (Sorghum bicolor L.) farm in Lyford, Texas, trialed different cover crop mixes and seeding rates and confirmed that cover cropping leads to significant soil moisture deficits and cash crop failure when rainfall is low …

Moisture Transport Associated With Southwest Monsoon Rainfall Over Sri Lanka In Relatively Wet And Dry Rainfall Years, Sherly Shelton
Department of Earth and Atmospheric Sciences: Faculty Publications
Atmospheric moisture transportation associated with the occurrence of relatively wet and dry southwest monsoon (SWM) years over Sri Lanka is still not fully understood. This study focused on investigating the role of moisture transport in contrast SWM years. We selected seven wet (SWMWet) and nine dry (SWMDry) years for 1985-2015 and found that the whole country experiences above-average (below average) rainfall in SWMWet (SWMDry) years. In SWMWet years, strengthening moisture-laden low-level jets (LLJ) from the Arabian Sea bring a large amount of moisture towards Sri Lanka. In contrast, the weakening of the …
Evaluating Changes In Visible To Short-Wave Infrared Spectral Reflectance Of Arctic Mosses In Response To Experimental Drying To Find The Best Predictors Of Moisture Content, Steven L. Unger
FIU Electronic Theses and Dissertations
Mosses are a dominant understory component in the Arctic and because of sparse canopy cover, contribute to spectral signals used in remote sensing estimates of various ecologically important characteristics such as productivity, phenology, and vegetation mapping. However, little is known about their contributions to community level spectra or how moisture content influences those spectral signals. Unlike vascular plants, mosses cannot actively regulate moisture content and are highly susceptible to desiccation. Previous research has shown that moss reflectance is sensitive to tissue moisture content. Here, a lab-controlled drying experiment was conducted to identify the best spectral predictors of moisture content of …
Impact Of Exposure On Thin Epoxy Overlay Performance, Abul Fazal Mazumder
Impact Of Exposure On Thin Epoxy Overlay Performance, Abul Fazal Mazumder
Dissertations
Thin epoxy overlays are used for improving the condition and extending the service life of bridge decks. The tensile bond pull-off strength, evaluated as per the ASTM C1583, is used as the performance indicator. A failure in the substrate with a tensile strength of 250 psi or greater is considered acceptable. However, the performance evaluated on in-service bridge decks shows inconsistent results. Laboratory studies by several researchers documented a distinct performance difference when the overlays are exposed to room temperatures in comparison to elevated temperatures. However, the most influential parameters such as concrete surface profile, thermal compatibility between overlay and …

Characterization Of Indoor Arenas Through An Anonymous Survey, Staci Mcgill, Morgan D. Hayes, Kimberly I. Tumlin, Robert Coleman
Biosystems and Agricultural Engineering Faculty Publications
Equine farms are building both stables for the horses to live in and additional facilities to train and work horses (Kidd et al., 1997). For many of these farms, an outdoor arena that has an all-weather footing is the first working facility built. During inclement weather the ability to train in the outdoor arenas is inhibited, which in turn means the trainers, riders, and farms lose income as money is only made when horses are working, training, and competing. Indoor arenas allow for horses to continue to be worked no matter the weather conditions. The equine industry contributes a total …
Electrical Characterization Of Conductive Concrete Containing Graphite Powder, K. I. M. Iqbal
Electrical Characterization Of Conductive Concrete Containing Graphite Powder, K. I. M. Iqbal
Theses and Dissertations
Electrically conductive concrete has various potential non-structural functions such as self-sensing, de-icing, and electromagnetic shielding. Since conductive concrete is a composite containing moisture and discrete conductive additives, its electrical properties are very complex. Understanding these properties is the fundamental requirement for developing its non-structural applications. In this research, graphite powder is used as a conductive additive with varying percentages (0% to 30%) by cement paste volume. Both AC impedance analysis and DC measurement are performed in both wet and dry conditions. The results show that the resistivity measured by DC are not consistent because of polarization before/during the measurement. On …

All over Ireland large numbers of people live in unsanitary conditions suffering poor indoor air quality, surface condensation and mould. Where the occupants are tenants the cause of the conditions and identification of the parties responsible can cause much stress. Condensation and mould growth on the internal surface of a room are caused by a combination of factors due to specific conditions. In severe cases, one of these factors may lead to surface condensation and/or mould growth, but in general, surface condensation and/or mould growth occurs when two or three of these occur together. Even though multiple causes and shared …
