Resumen

Proteins, lipids and structural changes in white sauces after being stored at –18°C and thawed by microwave and conventional oven were studied in this work. The total crude and soluble protein fractions were quantified by N-Kjeldahl. The acidity grade and oxidation spectrophotometric parameters (k232 and k 270) were used to analyse the lipid fraction. In addition, confocal scanning laser microscopy (CSLM) was used to study the structure of the sauce. The results showed that the total crude protein fraction increased in the thawed samples if compared to the freshly-prepared samples, mainly when microwave oven was used. However, the soluble protein fraction did not vary significantly (P < 0.05) among the different samples. Regarding the lipid changes, the acidity index did not show significant differences among the samples. K232 values of the microwave-thawed samples differed significantly from the freshly-prepared and the conventional-thawed samples. Furthermore, k270 values were significantly different between the samples thawed using the conventional oven and the freshly-prepared ones. CSLM images showed degradation of the starch granules and an increase of size in the fat globules due to thawing.

Resumen

The main purpose of this study was to research the influence of different drying methods on the physical and quality properties of dried shrimps. Shrimps were dried with conventional methods at 60, 70 and 80?C between 330 to 210 minutes and 190 to 110 minutes, in an oven and vacuum oven respectively. Drying time is shortened with the use of vacuum pump. The drying kinetics of the shrimp were studied, and effective moisture diffusion and activation energy were calculated for both methods. The Alibas model and the Midilli & Kucuk model provided the best experimental data with a high coefficient of determination (R2) for oven and the vacuum-oven techniques, respectively. The final dried products were characterized by investigating the colour characteristics, heavy metal content and by carrying out protein analyses. Rehydration ratio was also determined for the dehydrated shrimps. Drying conditions affected the colour features so that shrimps dried in ovens and vacuum ovens showed an increase in brightness and yellowness values and decrease in redness values. The concentration of As, Pb, Cd, Hg, Cu, Zn and Fe in the dried shrimp were within acceptable limits. The protein content of dried shrimp (~85%) is higher than undried shrimp (~20%).

Resumen

The oxidation stability of extra virgin and refined olive oils produced in different countries were studied under different conditions of microwave heating (microwave oven Electrolux, 2450 MHz, 500 W) and conventional heating (200°C). Oils were heated in a microwave oven and in a conventional oven for 0, 3, 6, 9, 12, 15, 20, 25, and 30 minutes. The evaluated parameters were peroxide value, content of conjugated dienes, conjugated trienes (determined by absorbance at 233 nm and 274 nm, respectively), and fatty acid composition by GC. During microwave and conventional heating peroxide values and contents of dienoic compounds differed significantly between control and the heated samples. The microwave treatment did not produce significantly greater amount of oxidation products than traditional heating.

Resumen

This paper assesses the sintering in a conventional oven and microwave oven of Ni-Zn ferrite. The samples were previously synthesized by combustion reaction in the microwave, and then sintered in a conventional oven and microwave oven 1200°C/2h with a heating rate of 5°C/min. The samples were characterized by: XRD, SEM and magnetic measurements by AGM. The results indicate the formation of inverse spinel crystalline phase of Ni-Zn ferrite, with inter-and intergranular porosity and average grain size of 0.15 µm and 0.30 µm, respectively for the samples sintered in a conventional oven and microwave oven. The sample sintered in conventional furnace showed a pattern characteristic of superparamagnetic materials with saturation magnetization of 7.6 emu.g-1, while in the microwave sintered sample showed a typical behavior of soft magnetic materials with saturation magnetization of 70 emu.g-1.

Resumen

ABSTRACT Over the past 15 years, multiple foodborne outbreaks have occurred in Canada due to the presence of Salmonella enterica in frozen breaded chicken products. These chicken products were raw and required cooking in conventional household ovens to inactivate any pathogens that they may have been harboring. During the course of food safety investigations associated with these outbreaks, many consumers reported using alternative household appliances such as air fryers to cook these products. The effectiveness of these appliances for the inactivation of pathogens in food is not known. Here, we compare the ability of a toaster oven, air fryer, deep fryer, and conventional oven to inactivate a cocktail of Salmonella Enteritidis in frozen breaded chicken strips. Deep frying was the most effective cooking method, demonstrating a median 7-log reduction; the conventional oven was next with a median 6-log reduction. Both the air fryer and toaster oven performed poorly, with respective median 4- and 3-log reductions. Overall, the results of this study suggest the revision of cooking instructions is required for the safe household use of toaster ovens and air fryers. HIGHLIGHTS

Resumen

This article reports a comparative study of experimental results obtained during the drying of Castilla-variety coffee beans from Santander, Colombia. They were performed by two means: thermal and electromagnetic radiation. Twenty experiments were carried out, ten tests in a microwave cavity at 2,450 MHz-1,080W, and ten tests using a conventional electric oven with temperature controlled at 50±2oC. Experiments were made using samples of coffee beans with parchment, without parchment, and of the only-parchment. For each sample, dimensionless moisture ratio and diffusion coefficients were determined, according to the second law of Fick. We found that the diffusion coefficient of the samples dried in a microwave cavity was twenty-two times higher than the diffusion coefficient of samples dried with thermal radiation. Likewise, it was observed that samples in conventional oven showed a uniform temperature, in contrast with those heated by microwave radiation. Such results are useful for designing hybrid systems for drying coffee beans.

Texto completo

Resumen

Multilevel inverters have attracted wide interest in both the academic community and the industry for the past decades. Therefore, the investigation and development of modulation strategies in multilevel inverters emerges as a necessity for the industry and researchers. In this doctoral thesis, alternative modulation methods suitable for three-level conventional single-phase inverters and especially for cascade H-bridge multilevel inverters are discussed and proposed. The theory of Equal Areas is reformed and presented and its modifications are proposed. These modifications are compared with other well-known modulation schemes, such as carrier-based modulation schemes and programmed pulse width modulation techniques. The advantage of the modified Equal Areas Pulse Width Modulation (EAPWM) is its algorithmic simplicity due to simple algebraic relationships, which results in less computational effort. A fully mathematical formulation for the Equal Areas modulation is proposed for both conventional and multilevel inverters. The EAPWM is shown to produce well-formed switched output voltages that have low total harmonic distortion at even low switching frequencies. The importance of this thesis is complimented by the results, produced after the implementation of EAPWM in multilevel inverters, which can be used as a more accurate reference when compared with other modulation strategies. Moreover, this direct modulation strategy has been extended to work on higher amplitude modulation ratios, in a linear manner, while entering the over modulation region. In this context, modified algorithms have been developed using different criteria for the calculation of the pulses’ width and their placement inside the time interval. The equal areas method, implemented in conventional single-phase inverters, uses odd pulse numbers per half cycle, holding integer frequency ratios in contrast to its implementation in multilevel inverters, where non-integer frequency ratios occur due to the level-by-level application. The application of the method is verified by simulations together with experimental work using a full-scale prototype inverter.

Resumen

The increasing demand of the frequency spectrum for land mobile satellite communication services has led to the approach of moving the current operating frequency up to EHF (30/20 GHz) band. In this thesis, the propagation characteristics of the EHF mobile satellite communication channel are estimated and modeled. Conventional and multiple trellis-coded modulation schemes designed for fading environment are considered for the EHF mobile satellite channel. The design criteria for optimum trellis-coded modulation scheme on the folding channel are studied. Through computer simulation, the performances of both coherent and differential trellis-coded modulation systems with selected coding schemes on the EHF channel models are evaluated. The effects of using channel state information and interleaving technique on the trellis-coded modulation systems are also studied. Finally the simulation results are presented and discussed.

The rapid growth of the number of devices and the gigantic amount of data present challenges to the healthy growth of telecommunication systems that is needed to support high-density environments. Multiple-antenna systems are deployed at base stations to support multiple users simultaneously on the same frequency, taking advantage of beamforming spatial diversity. In this thesis, we explore the application of antenna nulling in providing additional user coverage (as in increased number of supported users) over conventional beamforming. We consider, as a special case to validate the idea, the uplink line-of- sight narrowband transmission of a single base station equipped with uniform circular antenna array (UCA) through conventional, complete nulling, and optimal beamformers. We demonstrate, numerically and analytically, the average number of active users and outage probabilities under different beamformers, given a minimally acceptable signal-to-interference-and-noise (SINR) threshold and additional power margin. Variations of the antenna radius, number of antenna elements, and low- and high-SINR threshold are considered. We have shown a significant gain associated with the use of optimal beamformers instead of conventional beamformers. We discover that the improvements largely depend on the SINR threshold and is limited by the number of antenna elements for the unsaturated array and by the antenna aperture for the saturated array.

Resumen

In this study, catalytic activity of the Co and/or Pb-SBA-15 mesoporous catalysts in methane partial oxidation reaction was investigated. By using sol-gel, incipient wetness impregnation and post grafting method, SBA-15 samples are incorporated with Co and/or Pb at different weight loadings to provide a controlled geometry in nanometer scale. The characterization of the synthesized samples was done by XRD, N2 adsorption isotherms, FTIR, TEM images, Raman and XPS analysis. In the present study also, gas phase methane partial oxidation modeling and the synthesizing of mesoporous SBA-15 silica with different pore sizes were investigated. For the samples prepared by sol-gel method, XRD analysis showedthat cobalt exists in the form of Co3O4and Pb exist in the form of PbO. BET surface areas of the Co loaded catalysts are in the range of 479.5-640.1 m2/g. However, in Pb loaded samples, higher metal loading decrease the surface area up to 4.63 m2/g. Considering the both Co and Pb containing bi-metallic samples, TEM and BET results revealed that the ordered hexagonal mesostructure was fully destroyed. The samples prepared by incipient wetness impregnation and post grafting method characterized by using BET, TEM, Raman and XPS analysis. According to the BET results all the samples show ordered mesostructure in agreement with TEM results for all Co and/or SBA-15 mesoporous samples. TEM results also revealed that, the Co(5%) Pb(5%)-SBA-15 catalyst prepared by incipient wetness impregnation method possess big cobalt and lead oxide crystallines on the mesoporous structure. Raman analysis results indicated that cobalt exist in Co3O4 form. According to XPS results all samples containing cobalt include Co3O4. The partial oxidation of methane was carried out in a fixed bed flow-type reactor in a temperature range of 50&ndash
850°
C under atmospheric pressure.According to the reaction test results, the 0.5%Rh-Co-SBA15 catalyst shows the highest methane conversion (82%) and H2 selectivity. The non-precious metal show lower reactivities, addition of Pb to the Co-SBA-15 catalyst increases the catalytic activity and decrease the H2 production temperature.

Since the time of their arrival beginning around 2005, there remain approximately 46,000 African asylum seekers in Israel. The following paper reviews the foundations and implications of Israel’s political discourse in reference to the presence of this community. I situate the treatment of the asylum seekers in their relationship to the Jewish State, Zionist ideology, international refugee law, and Israel’s human rights community. I argue: 1) that the discourse surrounding the asylum seekers reflects larger changes within the ethos of the Jewish State and models of Israeli personhood; 2) that notions of “security” and “threat” in relation to the asylum seekers take on new meanings shaped by Israel’s ongoing demographic concerns; and 3) that the political response to the African asylum seekers sheds light on irreconcilable goals of the Zionist nation-building project seeking to both maintain a Jewish majority and liberate world Jewry from life segregated and isolated in the Diaspora.

Resumen

Oman faces a water resources crisis as the demand of fresh water increases day by day. Most of the renewable water resources in the country are directly or indirectly dependent on the rainfall. The Western Hajar Mountains extend to the borders with the UAE. This area is a very important source of ground water for both countries. A collaborative program to investigate the feasibility of rainfall enhancement over the Omani mountains by means of hygroscopic cloud seeding was implemented in the UAE during the summer of 2003 and 2004. Due to the complicated logistics and astronomical cost involved in the cloud seeding experiment, it is crucial that timely and accurate forecasts are made for these mesoscale storms. However, convective clouds of the Al Hajar Mountains are notoriously difficult to predict as they result from mesoscale circulation. This study developed forecasting techniques for seedable storms over the Western Hajar Mountains in the Sultanate of Oman. A period of 10 days (5th-14th of July 2004) was investigated in order to describe the differences in the atmospheric parameters between days when convection occurred and days which remained dry. The main ingredient for convective development is the influx of surface moisture from southeast over the Arabian Sea. This moisture often results from the circulation around the surface low over the central part of the Arabian Peninsula but may occasionally be caused by the sea breeze circulation. The northeasterly sea breeze moves in from the Gulf of Oman to the mountains where it converges with the southeasterly moist flow and this may result in the occurrence of convective clouds. Localized wind convergence zones near the mountains are good indicators of the onset of convection. The Oman Convection Index (OCI) was developed to replace the K-index (KI) and was found to provide a good indication of convective development over the mountains. A forecasting decision tree table for predicting convective storms over the Al Hajar Mountains is proposed where circulation criteria are stipulated as well as critical values for meteorological variables. The ingredients includes the location of the heat low over the centre of Arabian Peninsula, latent instability of the atmosphere, and critical values of mixing ratio and the OCI. This research results have shown that careful investigation and manipulation of the available data allow for increased accuracy in the forecast of convection. The OCI was developed to describe the conditions favorable for summer convection over the mountains of Oman specifically. The results show that the OCI fairs considerably better than the KI in identifying days when significant convection is likely to occur. However, the OCI is only one element of the forecasting techniques table. For truly significant convection to occur there are at least four other circulation criteria which should be satisfied. The forecasting decision tree table provides a systematic approach to the forecasting of convection of the mountains and therefore, for the first time in Oman, objective verification is possible and opens the door for improving these and other forecasting techniques. The techniques developed here may therefore contribute to future cloud seeding projects in the mountains of Oman.

Resumen

AbstractThis chapter examines the theoretical principles that underpin conventional deterrence and its evolution in practice over the past century. It disaggregates conventional deterrence approaches into four strategic categories based on their geographic scope and the nature of the threats they employ, and focuses in particular on strategies of punishment through resistance to an invader on the battlefield. It concludes with an assessment of the strengths and limitations of conventional and nuclear deterrence, and a set of summary principles for conventional deterrence strategy makers.

Resumen

Powder metallurgy is a highly established method for fabricating metals and metal matrix composites. An innovative hybrid sintering technique involving the use of microwaves and radiant heating is currently proposed. The use of microwaves to heat metallic materials is not common because it is a well known fact that bulk metals reflect microwaves and causes arching when placed inside a microwave oven. Microwave heating of materials is fundamentally different from conventional resistance heating and offer many benefits over conventional heating. In this study, aluminum, magnesium and a lead-free solder were selected as candidate materials and sintered using conventional sintering as well as a novel hybrid microwave assisted sintering. The sintered materials were hot extruded and characterized primarily in terms of physical and mechanical properties. An overall superior combination of hardness and tensile properties were realized in the case of microwave sintered samples when compared to the conventionally sintered samples.

Resumen

SWNTs were synthesized by laser vaporized CCVD (Catalytic Chemical Vapor Deposition). The diameter distribution and the purity of SWNTs synthesized at different temperatures, laser intensities and catalysts were investigated by Raman spectroscopy. Both of them tended to shift towards a larger area as reacting temperature or laser intensity was increased. Ni, Co and Fe played a catalytic role, though Ag and Cu were less effective at our experimental conditions. In addition, the conventional laser oven technique and laser vaporized CCVD technique were also compared. The diameter distribution of SWNTs which were synthesized by the conventional laser oven technique was narrower than that of SWNTs synthesized by the laser vaporized CCVD technique.

Resumen

The present study aims at investigating the effect of oscillating flow on thermal stratification in a gas oven. To date, the fan convectors are common to reduce thermal stratification inside various types of oven. The impetus of the present study is to investigate the feasibility of flow oscillation to achieve more uniform distribution of air temperature within an oven. To produce the flow oscillation, an acoustic woofer is vertically installed on the back of a gas oven. The operating frequency of the acoustic woofer is varied from 30 to 60 Hz. Three-dimensional measurements of air temperature inside the oven are implemented to evaluate temperature uniformity. The experimental results show that the oscillating flow with a specific frequency enhances air mixing dramatically, which results in the attenuation of thermal stratification inside the oven. The actual baking of sponge cake also shows that the convector using the flow oscillation can provide better results compared to the conventional fan convectors.

Resumen

The purpose of this research is to develop a process to use plasma decomposition of hydrocarbon liquids or clathrate hydrates in a microwave oven to produce fuel gas while simultaneously solidifying the carbon and synthesizing it into useful carbonized materials, such as CNTs or activated charcoal. Hydrogen gas with a purity of 60% to 80% can be extracted using a conventional microwave oven. This means that the energy efficiency of hydrogen production using this method is estimated to be approximately 50% of that by electrolysis of alkaline water and approximately 1% of that by the natural gas steam reforming method. However, this process has the added benefit of producing solid carbon at the same time. This method can be applied to a wide variety of waste liquids, or hydrate. Surplus electrical energy could be used to process waste liquids from homes and factories, and the resulting hydrogen energy could be stored and used.

Resumen

It has been realized that various chemical reactions are accelerated under irradiation of MW. Such Microwave chemistry is known as time-saving, clear and eco-friendly. MW ovens are world-wide domestic tools for cooking which can serve meals quickly. Regardless of its convenience, few understand the essential mechanism of MW ovens. For better understanding of MW chemistry, authors think it is necessary for to introduce elementary knowledge by holding a 1-day program of experiments by using microwave (MW) ovens.“Science with microwave oven”, 1-day program which we developed and named “Hirameki Tokimeki Science” was supported by Japan Society for the promotion of Science, has been performed over four years.More than 100 students of elementary and junior-high school have joined the program.Here we report the program, response from students.Program of experiments: “1: Dyeing handkerchief with onion peer (*1), 2: Cooking of pizza quickly yeast-leavened, 3: Preparation of shining slime with fluorescein dye synthesized in nonsolvent reaction. 4. Plasma in MW oven (*2), etc.”Students realized how MW accelerated chemical reactions and that dyeing under MW was faster and more fixed compared with the conventional methods. Besides, they could enjoy lunch with pizza and dealing with the slime, both they made. They had a good time with a bit of scientific knowledge. Through 1-day program, we can make science more familiar with students, and it will cause young students to become more interested in science, lead them to future research workers.In addition to the “Hirameki Tokimeki (Inspiration and Spark) Program, we have doneVolunteer activities at Ishinomaki, one of the most damaged cities at the Higashi Nihon Big Earthquake, in 2011.“Science with microwave oven” program surely gives students mysterious interest anddream for Science. That is “Inspire and Spark!” (*1) (*2)

Resumen

Abstract Carbon nanotubes (CNTs) have the unique ability to absorb microwave radiation and efficiently transfer the energy into substantial heat. When adequately dispersed in a thermoset polymer, such as polydimethylsiloxane (PDMS), the nanocomposite can be fully cured in seconds in a microwave oven rather than in hours in a convection oven. In this paper, cylindrical PDMS nanocomposites containing well-dispersed CNTs are fabricated by either microwave-curing or conventional thermal-curing. The mechanical, electrical, and piezoresistive properties of the fabricated samples are compared to understand the effects of different curing methods. Microwave-cured nanocomposites exhibit a significantly reduced compressive modulus for different CNT loadings. In addition, the electrical conductivity of microwave-cured nanocomposites is significantly enhanced over the thermally-cured counterparts. Experimental results demonstrate that the one-step microwave-curing procedure can improve the electrical conductivity of 1 wt% nanocomposites by almost 150 % over thermal-curing. However, their piezoresistive sensitivity remains remarkably similar, showing the potential for microwave-curing to replace thermal-curing for the manufacturing of highly flexible CNT-based nanocomposites.

Resumen

Worldwide interest in using recycled materials in flexible pavements as an alternative to virgin materials has increased significantly over the past few decades. Therefore, recycling has been utilized in pavement maintenance and rehabilitation activities. Three types of in-place recycling technologies have been introduced since the late 70s: hot in-place recycling, cold in-place recycling, and full-depth reclamation. The main objectives of this project are to develop a framework and a life-cycle assessment (LCA) methodology to evaluate maintenance and rehabilitation treatments, specifically in-place recycling and conventional paving methods, and develop a LCA tool utilizing Visual Basic for Applications (VBA) to help local and state highway agencies evaluate environmental benefits and tradeoffs of in-place recycling techniques as compared to conventional rehabilitation methods at each life-cycle stage from the material extraction to the end of life. The ultimate outcome of this study is the development of a framework and a user-friendly LCA tool that assesses the environmental impact of a wide range of pavement treatments, including in-place recycling, conventional methods, and surface treatments. The developed tool provides pavement industry practitioners, consultants, and agencies the opportunity to complement their projects’ economic and social assessment with the environmental impacts quantification. In addition, the tool presents the main factors that impact produced emissions and energy consumed at every stage of the pavement life cycle due to treatments. The tool provides detailed information such as fuel usage analysis of in-place recycling based on field data.

Resumen

Trichloroethylene (TCE) releases from leaks and spills next to a large government building occurred over several decades with the most recent event occurring 20 years ago. In response to a perceived conventional vapor intrusion (VI) issue a sub-slab depressurization system (SSDS) was installed 6 years ago. The SSDS is operating within design limits and has achieved building TCE vapor concentration reductions. However, subsequent periodic TCE vapor spikes based on daily HAPSITE™ measurements indicate additional source(s). Two rounds of smoke tests conducted in 2017 and 2018 involved introduction of smoke into a sanitary sewer and storm drain manholes located on effluent lines coming from the building until smoke was observed exiting system vents on the roof. Smoke testing revealed many leaks in both the storm sewer and sanitary sewer systems within the building. Sleuthing of the VI source term using a portable HAPSITE™ indicate elevated vapor TCE levels correspond with observed smoke emanation from utility lines. In some instances, smoke odors were perceived but no leak or suspect pipe was identified suggesting the odor originates from an unidentified pipe located behind or enclosed in a wall. Sleuthing activities also found building roof materials explain some of the elevated TCE levels on the 2nd floor. A relationship was found between TCE concentrations in the roof truss area, plenum space above 2nd floor offices, and breathing zone of 2nd floor offices. Installation of an external blower in the roof truss space has greatly reduced TCE levels in the plenum and office spaces. Preferential VI pathways and unexpected source terms may be overlooked mechanisms as compared to conventional VI.

Resumen

There is a high degree of freedom and flexibility in the way to integrate renewable process heat in industrial processes. Nearly in every industrial or commercial application various heat sinks can be found, which are suitable to be supplied by renewable heat, e.g. from solar thermal, heat pumps, biomass or others. But in contrast to conventional fossil fuel powered heating systems, most renewable heating technologies are more sensitive to the requirements defined by the specific demand of the industrial company. Fossil fuel-based systems benefit from their indifference to process temperatures in terms of energy efficiency, their flexibility with respect to part-load as well as on-off operation, and the fuel as a (unlimited) chemical storage. In contrast, the required temperature and the temporal course of the heat demand over the year determine whether a certain regenerative heat generator is technically feasible at all or at least significantly influence parameters like efficiency or coverage rate.

Resumen

Over the last few decades, in-place recycling of asphalt pavements has seen increased use by the highway industry, primarily to take a dvantage of potential cost and logistical savings compared to conventional reconstruction. More recently, the U.S. Navy and Federal Aviation Administration have allowed recycling to be used on airfields with lighter traffic. This report contains a discussion of in-place recycling design considerations obtained from a literature review of its use in the highway industry. Observations developed from a review of airfield pavement projects that have utilized recycling is also included. A structural analysis was performed using the Pavement-Transportation Computer Assisted Structural Engineering (PCASE) tool to determine typical stiffness values that recycled layers must achieve to support various types of military aircraft traffic for different pavement structures. Overall, in-place recycling is recommended for consideration as a rehabilitati on technique for military airfield pavements, and further investigation is recommended before it is implemented it into design guidance.

Resumen

Type K cement offers a lower slump than conventional concrete, even at a higher water-to-cement ratio. Therefore, a suitable chemical admixture should be added to the Type K concrete mix design at a feasible dosage to achieve and retain target slump. In this project, a compatibility study was performed for Type K concrete with commercially available water-reducing and air-entraining admixtures. Slump and air content losses were measured over a period of 60 minutes after mixing and a particular mid-range water-reducing admixture was found to retain slump effectively. Furthermore, no significant difference in admixture interaction between conventional and Type K concrete was observed. Another concern regarding the use of Type K concrete is that its higher water-to-cement ratio can potentially lead to higher permeability and durability issues. This study also explored the effectiveness of presoaked lightweight aggregates in providing extra water for Type K hydration without increasing the water-to-cement ratio. Permeability of concrete was measured to validate that the use of presoaked lightweight aggregates can lower water adsorption in Type K concrete, enhancing its durability. Extensive data analysis was performed to link the small-scale material test results with a structural test performed at Saint Louis University. A consistent relation was established in most cases, validating the effectiveness of both testing methods in understanding the performance of proposed shrinkage-mitigation strategies. Stress analysis was performed to rank the mitigation strategies. Type K incorporation is reported to be the most effective method for shrinkage-related crack mitigation among the mixes tested in this study. The second-best choice is the use of Type K in combination with either presoaked lightweight aggregates or shrinkage-reducing admixtures. All mitigation strategies tested in this work were proved to be significantly better than using no mitigation strategy.

Resumen

Terminal ballistics of concrete is of extreme importance to the military and civil communities. Over the past few decades, ultra‐high performance concrete (UHPC) has been developed for various applications in the design of protective structures because UHPC has an enhanced ballistic resistance over conventional strength concrete. Developing predictive numerical models of UHPC subjected to penetration is critical in understanding the material's enhanced performance. This study employs the advanced fundamental concrete (AFC) model, and it runs inside the reproducing kernel particle method (RKPM)‐based code known as the nonlinear meshfree analysis program (NMAP). NMAP is advantageous for modeling impact and penetration problems that exhibit extreme deformation and material fragmentation. A comprehensive experimental study was conducted to characterize the UHPC. The investigation consisted of fracture toughness testing, the utilization of nondestructive microcomputed tomography analysis, and projectile penetration shots on the UHPC targets. To improve the accuracy of the model, a new scaled damage evolution law (SDEL) is employed within the microcrack informed damage model. During the homogenized macroscopic calculation, the corresponding microscopic cell needs to be dimensionally equivalent to the mesh dimension when the partial differential equation becomes ill posed and strain softening ensues. Results of numerical investigations will be compared with results of penetration experiments.

A framework and pilot tool for the risk-based prioritization and grouping of nano-enabled consumer products.

Resumen

The use of engineered nanomaterials (ENMs) in consumer products has expanded rapidly, revealing both innovative improvements over conventional materials, and the potential for novel risks to human health and the environment. As the number of new nano-enabled products and the volume of toxicity data on ENMs continues to grow, regulatory agencies like the U.S. Consumer Product Safety Commission (CPSC) – a small, independent federal agency responsible for protecting consumers from unreasonable risks associated with product use – will require the ability to screen and group a diverse array of nano-enabled consumer products based on their potential risks to consumers. Such prioritization would allow efficient allocation of limited resources for subsequent testing and evaluation of high-risk products and materials. To enable this grouping and prioritization for further testing, we developed a framework that establishes a prioritization score by evaluating a nano-enabled product's potential hazard and exposure, as well as additional consideration of regulatory importance. We integrate the framework into a pilot version software tool and, using a hypothetical case study, we demonstrate that the tool can effectively rank nano-enabled consumer products and can be adjusted for use by agencies with different priorities. The proposed decision-analytical framework and pilot-version tool presented here could enable a regulatory agency like the CPSC to triage reported safety concerns more effectively and allocate limited resources more efficiently.

Resumen

Could the future of our planet be decided on Zoom? The feasibility of “online climate negotiations” was the issue the OnCliNe project initially set out to assess. However, experiences over the last 18 months illustrated that many of the diverse activities organised under the umbrella of the United Nations Framework Convention on Climate Change (UNFCCC) could be held online, albeit with challenges. The real question was whether they could be held in ways that increase the effectiveness, inclusiveness and transparency of the UNFCCC process. This report reflects the sentiment of many stakeholders that there is an opportunity to harness the interruption and introspection that the pandemic imposed into a “positive disruption” of the process. If actions taken now can transcend the tendency to return to “business as usual” as soon as circumstances allow, and instead work towards a meaningful transformation of the climate talks, the UNFCCC process can be made more fit for purpose for tackling one of humanity’s greatest challenges. This will require creativity, courage, and active and decisive leadership.

Resumen

High-volume fly ash concrete (HVFAC) is more cost-efficient, sustainable, and durable than conventional concrete. This report presents a state-of-the-art review of HVFAC properties and different fly ash characterization methods. The main challenges identified for HVFAC for pavements are its early-age properties such as air entrainment, setting time, and strength gain, which are the focus of this research. Five fly ash sources in Illinois have been repeatedly characterized through x-ray diffraction, x-ray fluorescence, and laser diffraction over time. The fly ash oxide compositions from the same source but different quarterly samples were overall consistent with most variations observed in SO3 and MgO content. The minerals present in various fly ash sources were similar over multiple quarters, with the mineral content varying. The types of carbon present in the fly ash were also characterized through x-ray photoelectron spectroscopy, loss on ignition, and foam index tests. A new computer vision–based digital foam index test was developed to automatically capture and quantify a video of the foam layer for better operator and laboratory reliability. The heat of hydration and setting times of HVFAC mixes for different cement and fly ash sources as well as chemical admixtures were investigated using an isothermal calorimeter. Class C HVFAC mixes had a higher sulfate imbalance than Class F mixes. The addition of chemical admixtures (both PCE- and lignosulfonate-based) delayed the hydration, with the delay higher for the PCE-based admixture. Both micro- and nano-limestone replacement were successful in accelerating the setting times, with nano-limestone being more effective than micro-limestone. A field test section constructed of HVFAC showed the feasibility and importance of using the noncontact ultrasound device to measure the final setting time as well as determine the saw-cutting time. Moreover, field implementation of the maturity method based on wireless thermal sensors demonstrated its viability for early opening strength, and only a few sensors with pavement depth are needed to estimate the field maturity.
