Abstract:
. Various types of protection are used in order to ensure rigidity in earth dam slopes and dumped rip-rap and precast and cast-in-situ reinforced plates are the most commonly used for this purpose. Durability and reliability of the protections mainly depend on the fact whether protection parameters have been correctly calculated and correspondingly observed during the process of protection creation, the main protection parameters are material diameter of dumped rip-rap and thickness of reinforced plates. Values of protection parameters calculated in accordance to the existing formulae significantly differ among themselves. Some of these formulae are acceptable for small water reservoirs in Belarus and provide actual results only for large water reservoirs where a wave height reaches two metres and even more. A new calculation methodology which is suitable for Belarusian water reservoirs of various size is proposed with the purpose to determine diameter of dumped rip-rap material and thickness of plates for earth dam slope protection in the zone of active wave impact. The methodology has been developed on the basis of the theory pertaining to limit equilibrium of slope shearing and holding forces. While calculating diameter of dumped rip-rap material the following shearing forces have been taken into account: uplift wave pres- sure depending on wave height; drag force which is formed on the slope due to back sweep of wave; shearing component of protection material gravity force which is dependent on preselected slope ratio. Holding forces are determined with due ac- count of main physical and mechanical properties of dumped rip-rap material: density of particles in water suspension, porosi- ty, internal friction and holding component of protection material gravity force. While developing methodology for calcula- tion of reinforced concrete plate thickness a drag force has not been taken into account because the flow which is formed on the plate surface does not exert an influence on their equilibrium. Bottom slope zone where hydrodynamic pressure is created by bottom velocity has usually a reduced-weight protection in the form of broken stone, gravel and finely broken stone rip-rap. Dependences for determination of dumped rip-rap fineness have been obtained as a result of slope rigidity criterion conversion. The proposed formulae for calculation of earth dam slope protection parameters can be recommended for applica- tion in design organizations.

Abstract:
Room-temperature phosphorescent (RTP) materials have been attracting tremendous interest, owing to their unique material characteristics and potential applications for state-of-the-art optoelectronic devices. Recently, we reported the synthesis and fundamental photophysical properties of new RTP materials based on benzil, i.e., fluorinated monobenzil derivative and fluorinated and non-fluorinated bisbenzil derivative analogues [Yamada, S. et al., Beilstein J. Org. Chem. 2020, 16, 1154–1162.]. To deeply understand their RTP properties, we investigated the excited-state dynamics and photostability of the derivatives by means of time-resolved and steady-state photoluminescence spectroscopies. For these derivatives, clear RTP emissions with lifetimes on the microsecond timescale were identified. Among them, the monobenzil derivative was found to be the most efficient RTP material, showing both the longest lifetime and highest amplitude RTP emission. Time-resolved photoluminescence spectra, measured at 77 K, and density functional theory calculations revealed the existence of a second excited triplet state in the vicinity of the first excited singlet state for the monobenzil derivative, indicative of the presence of a fast intersystem crossing pathway. The correlation between the excited state dynamics, emission properties, and conformational flexibility of the three derivatives is discussed.

Abstract:
SummaryObjective: To evaluate the presence of residual disc material within the vertebral canal following hemilaminectomy in chondrodystrophic dogs with thoracolumbar intervertebral disc disease.Methods: Forty dogs were treated by hemilaminectomy. Computed tomography was performed preoperatively and immediately postoperatively. The vertebral canal height, width, area, and herniated disc material area were measured. Maximum filling percentage (MFP), residual disc percentage (RDP), maximum residual filling percentage (MRFP), and residual filling percentage (RFP) were calculated. Clinical outcome was determined by telephone interviews.Results: Residual disc material was present in 100% of the dogs. Mean MFP = 55.4% (range 25.9–82.3%; median 56.9%). Mean RDP = 50.3% (range 2.6–155.8%; median 47.9%). Mean MRFP = 30.8% (range 4.9–60%; median 30.1%). Mean RFP = 19.8% (range 4.8–45%; median 19.0%). All dogs were ambulatory with voluntary urination at the long-term follow-up (range: 88–735 days).Clinical significance: Residual disc was present in all dogs following hemilaminectomy for intervertebral disc disease. Residual disc was not associated with failure to achieve functional recovery in these cases.

Abstract:
To achieve efficient polymer-based room-temperature phosphorescence (RTP) materials, covalently embedding phosphors into the polymer matrix appeared as the most appealing approach. However, it is still highly challenging to fabricate RTP materials on a large scale because of the inefficient binding engineering and time-consuming covalent reactions. Here, we have proposed a scalable preparation approach for RTP materials by the facile B─O click reaction between boronic acid–modified phosphors and polyhydroxy polymer matrix. The ab initio molecular dynamics simulations demonstrated that the phosphors were effectively immobilized, resulting in the suppressed nonradiative transitions and activated RTP emission. In comparison to the reported covalent binding time of several hours, such a B─O click reaction can be accomplished within 20 s under ambient environment. The developed strategy simplified the construction of polymer-based RTP polymeric materials by the introduction of facile click chemistry. Our success provides inspirations and possibilities for the scale-up production of RTP materials.

Full text
Abstract:
The present study aims to investigate reclaimed asphalt pavement (RAP) materials for utilization for a pavement base layer material with the goal towards increasing the reutilization of materials and the movement towards increased pavement sustainability. Reduced cost for materials and transportation of materials, overall environmental benefits and many other advantages have led to increased interests in utilizing RAP in pavements including as base materials for highway/roadway construction projects. The potential advantages of utilizing RAP as an unbound base material are known; however, its overall application is still limited partially due to the lack of systematic evaluation studies for the parameterization of RAPs mechanical behavior in pavement design. With this in mind, the current investigation focuses on the resilient modulus (Mr) properties of RAP aggregates in terms of a material’s elastic response. Experimental data from tri-axial stress tests on specimens consisting of RAP, aggregates and a mixture of both materials are investigated. A number of constitutive models for the description of mechanical behavior of RAP materials are investigated. The required procedures for determining the constitutive constants of the constitutive models is outlined for the aforementioned materials. A comparative analysis is applied, and the related results are evaluated. The main conclusion is that RAP materials can be utilized as a base material in the framework of pavement sustainability, as its behavior under loading conditions are similar to virgin aggregate (VA) materials and can be simulated by using appropriate constitutive models for pavement design processes.

Abstract:
Pure organic persistent room temperature phosphorescence (RTP) has shown great potential in information encryption, optoelectronic devices, and bio-applications. However, trace impurities are generated in synthesis, causing unpredictable effects on the luminescence properties. Here, an impurity is isolated from a pure organic RTP system and structurally characterized that caused an unusual ultralong RTP in matrix even at 0.01 mole percent content. Inspired by this effect, a series of compounds are screened out to form the bicomponent RTP system by the trace ingredient incorporation method. The RTP quantum yields reach as high as 74.2%, and the lifetimes reach up to 430 ms. Flexible application of trace ingredients to construct RTP materials has become an eye-catching strategy with high efficiency, economy, and potential for applications as well as easy preparation.

Abstract:
Long-persistent luminescence based on purely inorganic and/or organic compounds has recently attracted much attention in a wide variety of fields including illumination, biological imaging, and information safety. However, simultaneously tuning the static and dynamic afterglow performance still presents a challenge. In this work, we put forward a new route of organic-doped inorganic framework to achieve wide-range and multicolor ultralong room-temperature phosphorescence (RTP). Through a facile hydrothermal method, phosphor (tetrafluoroterephthalic acid (TFTPA)) into the CdCO3 (or Zn2(OH)2CO3) host matrix exhibits an excitation-dependent colorful RTP due to the formation of diverse molecular aggregations with multicentral luminescence. The RTP lifetime of the doped organic/inorganic hybrids is greatly enhanced (313 times) compared to the pristine TFTPA. The high RTP quantum yield (43.9%) and good stability guarantee their easy visualization in both ambient and extreme conditions (such as acidic/basic solutions and an oxygen environment). Further codoped inorganic ions (Mn2+ and Pb2+) afford the hybrid materials with a novel time-resolved tunable afterglow emission, and the excitation-dependent RTP color is highly adjustable from dark blue to red, covering nearly the whole visible spectrum and outperforming the current state-of-the-art RTP materials. Therefore, this work not only describes a combined codoping and multicentral strategy to obtain statically and dynamically tunable long-persistent luminescence but also provides great opportunity for the use of organic-inorganic hybrid materials in multilevel anticounterfeiting and multicolor display applications.

Abstract:
The thermal column at the TRIGA PUSPATI (RTP) research reactor can produce thermal neutron. However, the optimization on the thermal neutron flux produced should be performed to gain a sufficient thermal neutron for boron neutron capture therapy purpose. Thus, the objective of this review is to optimize the thermal neutron flux by designing the collimator with different materials at the thermal column. In order to fulfil the requirement, set by the IAEA standard, the study of Boron Neutron Capture Therapy (BNCT) around the world was being reviewed to study the suitable measurement, material, design, and modification for BNCT at the thermal column of TRIGA MARK-II, Malaysia. Initially, the BNCT mechanisms and history was review. Then, this paper review on the design and modifications for BNCT purpose around the world. Based on this review, suitable material and design can be used for the BNCT in Malaysia. Moreover, this paper also reviews the current status of BNCT at the RTP with the measurement of the thermal neutron flux was conducted along the thermal column at 250 kW. The thermal column of RTP was divided into 3 phases (Phase 1, Phase 2 and Phase 3) so that an accurate measurement can be obtained by using gold foil activation method. This value was used as a benchmark for the neutron flux produced from the thermal column. The reviewed demonstrated that the final thermal neutron flux produced was significantly for BNCT purpose.

Full text
Abstract:
Use of high percentage of Reclaimed Asphalt Pavement (RAP) material in Hot Mix Asphalt is one of the several sustainable construction alternatives being considered by many Departments of Transportation (DOT). Use of RAP in HMA helps in reducing the consumption of virgin aggregates and binder and construction cost and conserving energy. Although most of the US state agencies allow the use of 30% or more RAP in the design of Hot Mix Asphalt (HMA), the current average RAP usage is only about 10 to 20%. This is because of the uncertainty about the performance of HMA mixes with a high RAP content. Several factors influence the performance of the HMA mixes with a high RAP content. Recent research has shown that the use of a high RAP content in HMA with rejuvenators is successful in reducing the stiffness of the RAP mixes, and thereby improving their performance. The present work is carried out to explore the feasibility of using a high RAP content of 50% in a binder layer HMA with the addition of rejuvenators. Ultrasonic Pulse Velocity (UPV) test was carried out to compare the stiffness of the RAP mixes with and without the addition of rejuvenators. Moisture Induced Stress Test (MIST) was conducted to study the effect of moisture damage on the HMA mixes with high RAP content. The Indirect Tensile Strength Test (ITS) was used to determine the strength of the HMA mixes with high RAP content. In addition, creep compliance and Semicircular Bend (SCB) tests were carried out to determine the cracking potential and fracture strength of the mixes respectively. The addition of rejuvenators was found to significantly reduce the stiffness of the mix with high RAP content. The predicted complex shear modulus (G*) obtained from the Hirsch model and performance grading tests on extracted binders confirmed the effectiveness of the addition of rejuvenators in reducing the stiffness of recycled asphalt binder in the recycled mixes.

Full text
Abstract:
The primary work reported in this thesis is concerned mainly with the effects of different mixing methods and RAP materials on homogeneity and mechanical properties of hot recycled asphalt mixtures. The recycled asphalt mixture conforms to the requirement of BS 4987-1 (2005) for dense bitumen macadam size 10 mm (DBM 10 mm). The proportion of RAP in the recycled mixture is 40%. RAP materials are artificially aged and processed in the laboratory to prevent the variability of RAP gradation, bitumen content, and the origin. Laboratory RAP is also used to assure that every single RAP particle is an agglomerate of RAP aggregate and binder. The mixing procedures include Black Rock (BR), Complete Blending (CB), the SHRP procedure, and a newly developed field simulation method (FS). The primary difference between these methods is the mixing mechanism. The BR case implies the situation in which there is completely no interaction between RAP and virgin binder. On the contrary, RAP and virgin binder are fully interacted in the CB case. The mixing procedures for BR and CB cases conform to those for conventional asphalt mixtures. However, the bitumen for BR case is pure virgin bitumen. In addition, the bitumen for CB is the blend between RAP and virgin binder. The RAP/virgin binder proportion is 4/6. In the SHRP method, RAP is preheated at 110oC for two hours before being mixed with virgin aggregate and binder for 2 minutes at 130oC. In the FS method on the contrary, the mixing procedure duplicates what occurs in the asphalt mixing plant. RAP is mixed with superheated virgin aggregate (215oC) for different durations before this combination is blended with virgin bitumen for 2 minutes at 130oC. The RAP/superheated virgin aggregate mixing duration starts from short mixing time where RAP still exists at approximately original size and gradually increases until the change in RAP lump size is insignificant. Depending on the size of RAP used, RAP/superheated virgin aggregate mixing duration varies from 1 to 8 minutes. The homogeneity of hot recycled asphalt mixture is examined by using virgin binder with a different colour from that of RAP binder. The colour of virgin binder is obtained by mixing clear binder (Shell Mexphalt C 160/220 Pen) with iron oxide pigment. The proportion of pigment is 10% by weight of the binder making this binder red. The use of virgin binder with different colour from that of RAP binder helps to clearly differentiate the locations of RAP and virgin materials. Surfaces of slices cut from compacted recycled specimens are photographed by digital camera. The analysis of these surfaces in vertical order allows the locations of RAP material to be qualitatively identified in a 3D manner. Stiffness modulus values of samples for homogeneity assessment are also determined by indirect tensile stiffness test. The stiffness test is carried out in four directions along the circumference of each specimen with 45o angular increments. The experimental results show that the stiffness measurement in four directions can indicate the heterogeneity of recycled mixture. The variation in stiffness values in different measured directions will be substantial for heterogeneous mixtures and minor in the case where recycled mixtures are homogeneous. The results indicate there are mutual relations between mixing effort, homogeneity, and stiffness values of recycled asphalt mixtures. The longer mixing time will enhance the homogeneity and reduce the variation in stiffness values of recycled mixture. In addition, as more RAP and virgin binder are incorporated, the stiffness values of recycled mixture generally increase once the mixing time is extended. As the clear binder is dyed red by 10% by weight of iron oxide, the proportion of the pigment certainly alters the flow characteristic of binder. This might affect the mixing process and rejuvenating effect between virgin and aged binder. Therefore, the effects of mixing methods and RAP sizes on mechanical performance of hot recycled asphalt mixtures are further investigated using normal straight run bitumen 160/220 Pen as virgin binder. The assessment indicators include stiffness modulus, resistance to fatigue damage, and resistance to permanent deformation. The experimental results indicate that the conventional laboratory mixing method (SHRP) tends to overestimate the mechanical properties of recycled asphalt mixture. The long RAP preheating time that never exists in the industry coincidentally enhances the reaction between RAP and virgin binder. The long RAP preheating time also slightly alters the properties of RAP binder. For the FS method, the increase in mixing duration significantly improves the homogeneity level of recycled mixtures. The homogeneity level is also substantially affected by the size of RAP material. For the same mixing effort, the mixtures comprised of small RAP are generally more homogeneous than those made from larger RAP. The more homogeneous the mixture, the more interaction between RAP and virgin binder. Therefore, recycled mixtures become stiffer and have better resistance to permanent deformation and fatigue failure. A slightly linear increase in stiffness can result in an exponential increase in fatigue life of the recycled mixture. The mechanical properties including stiffness modulus, resistance to fatigue damage, and resistance to permanent deformation of hot recycled asphalt mixtures are not similar to those of the BR or CB mixtures, even at the favourable condition where RAP is preheated for 2 hours at 110oC in the SHRP method and 8 minutes mixing duration in the FS method. This implies that RAP does not act as Black Rock. In addition, the assumption that RAP and virgin binder are fully blended also never exists in the recycled asphalt production process.

Materiel Returns Program (MRP) credits have increased 1st Marine Logistics Group's (1st MLG) total obligation authority by an average of 27% annually since 2008. However, 1st MLG has been unable to leverage the MRP in budget execution due to an inability to forecast future credits. The purpose of this research is to determine whether analysis of historical MRP credits at 1st MLG could enable the comptroller to forecast future credits, which would enable 1st MLG to leverage MRP credits and budget more efficiently in a constrained fiscal environment. This research utilized descriptive analysis of historical credits to identify systemic patterns or trends associated with MRP. The analysis of MRP credits focused on two specific areas: (1) the accuracy of credit estimates provided by the sources of supply (SOSs), and (2) the amount of time it took for 1st MLG to receive the actual credit. The primary finding of this research was that 1st MLG should be able to forecast MRP credits. The research showed that historically over a two-year period, SOSs accurately estimated credits 88.3% of the time and SOSs issued 95% of all actual credits within 90 days of 1st MLG submitting an item into MRP.

Functional Capabilities of Neonatal RTE are more Diverse than Adult RTE." Scholarly Repository, 2008. http://scholarlyrepository.miami.edu/oa_dissertations/139.

Full text
Abstract:
Neonatal immune responses are typically deficient against a wide variety of antigens, including alloantigens, vaccine antigens, and infectious agents. These responses are characterized by Th2-skewed cytokine production, and deficient Th1 and cytotoxic responses. However, these deficient responses can be boosted to adult levels by the use of strong, Th1 promoting agents. This demonstrates that neonates are capable of developing mature immune responses under specific conditions. Using two different murine models, we have found that neonates develop robust Th and cytotoxic responses, which under some antigenic conditions significantly exceed those of adults. First, using a model of early life exposure to noninherited maternal antigens (NIMA), we found that murine neonates develop robust in vivo cytotoxic responses to low doses of alloantigens. Importantly, primary in vivo cytotoxic responses to alloantigen developed during the neonatal period, and persisted into adulthood. Neonates developed similar memory cytotoxic responses to donor spleen cells, bone marrow, and stem cell-enriched (Lin-) bone marrow cells, suggesting that the exposure dose is more important than the type of transplanted donor cell for the development of cytotoxicity. NIMA-exposed neonates also developed vigorous primary and memory allospecific Th1/Th2 responses which exceeded the responses of adults. These findings suggest that early exposure to low levels of NIMA may lead to long term immunological priming of all arms of T cell adaptive immunity. Second, we characterized the phenotype and function of neonatal recent thymic emigrants (RTE). RTE are the predominant cell type in murine neonates, and are present at higher frequencies within the neonatal CD4+ compartment than in adults. Our data demonstrate that RTE from murine neonates and adults are phenotypically and functionally distinct. In particular, although the magnitude of RTE cytokine responses from both age groups is dependent on the conditions of activation, neonatal RTE consistently exhibited higher levels of effector cytokine production than adult RTE. In particular, activation of neonatal RTE in the presence of IL-7 lead to greatly increased IFNgamma production, while adult responses were not altered. Overall, neonatal RTE responses were more plastic than those of adult RTE, as both Th1 and Th2 responses were altered in neonates using various activation conditions, while only Th2 responses were consistently changed in adults. Finally, in contrast to adult RTE, neonatal RTE proliferated in response to IL-7 stimulation at very early timepoints. This was associated with faster kinetics of IL-7Ralpha downregulation and higher levels of pSTAT5 in neonatal RTE. These quantitative and qualitative differences in neonatal RTE populations may largely explain the diverse responses that are elicited in neonates in response to different antigens, especially under those conditions in which Th1 responses are enhanced (i.e., exposure to NIMA alloantigens). Taken together, these data demonstrate that neonatal T cell responses are actually highly plastic, instead of intrinsically deficient. Furthermore, if given optimal stimulation conditions, neonatal responses can actually exceed those produced by adults.

Abstract:
AbstractThe Resilience Articulation Point (RAP) model aims to provision a probabilistic fault abstraction and error propagation concept for various forms of variability related faults in deep sub-micron CMOS technologies at the semiconductor material or device levels. RAP assumes that each of such physical faults will eventually manifest as a single- or multi-bit binary signal inversion or out-of-specification delay in a signal transition between bit values. When probabilistic error functions for specific fault origins are known at the bit or signal level, knowledge about the unit of design and its environment allow the transformation of the bit-related error functions into characteristic higher layer representations, such as error functions for data words, finite state machine (FSM) states, IP macro-interfaces, or software variables. Thus, design concerns can be investigated at higher abstraction layers without the necessity to further consider the full details of lower levels of design. This chapter introduces the ideas of RAP based on examples of particle strike, noise and voltage drop induced bit errors in SRAM cells. Furthermore, we show by different examples how probabilistic bit flips are systematically abstracted and propagated towards instruction and data vulnerability at MPSoC architecture level, and how RAP can be applied for dynamic testing and application-level optimizations in an autonomous robot scenario.

Abstract:
AbstractThere are severe environmental and ecological issues once we evaluate the architecture industry with LCA (Life Cycle Assessment), such as emission of CO2 caused by necessary high temperature for producing cement and significant amounts of Construction Demolition Waste (CDW) in deteriorated and obsolete buildings. One of the ways to solve these problems is Bio-Material. CELLULOSE and CHITON is the 1st and 2nd abundant substance in nature (Duro-Royo, J.: Aguahoja_Programmable Water-based Biocomposites for Digital Design and Fabrication across Scales. MIT, pp. 1–3 (2019)), which means significantly potential for architectural dimension production. Meanwhile, renewability and biodegradability make it more conducive to the current problem of construction pollution. The purpose of this study is to explore Cellulose Based Biomaterial and bring it into architectural scale additive manufacture that engages with performance in the material development, with respect to time of solidification and control of shrinkage, as well as offering mechanical strength. At present, the experiments have proved the possibility of developing a cellulose-chitosan- based composite into 3D-Printing Construction Material (Sanandiya, N.D., Vijay, Y., Dimopoulou, M., Dritsas, S., Fernandez, J.G.: Large-scale additive manufacturing with bioinspired cellulosic materials. Sci. Rep. 8(1), 1–5 (2018)). Moreover, The research shows that the characteristics (Such as waterproof, bending, compression, tensile, transparency) of the composite can be enhanced by different additives (such as xanthan gum, paper fiber, flour), which means it can be customized into various architectural components based on Performance Directional Optimization. This solution has a positive effect on environmental impact reduction and is of great significance in putting the architectural construction industry into a more environment-friendly and smart state.

Abstract:
Reinforced Thermoplastic Pipe (RTP) is a new technology that is reducing the cost of constructing oil and gas gathering pipelines while improving reliability. The following material will be described: RTP construction, materials, performance, compatibility, joining systems, installation methodologies, and carbon dioxide (CO2) specific test results. RTP combines high performing materials such as bimodal high density polyethylene with high strength reinforcing fibers in a unique construction to create a spoolable high pressure pipeline system. This construction is well suited to upstream flow line and gathering applications as well as distribution applications. The primary benefit of RTP is realized by the installation methodologies available which contribute overall project savings of up to 30–50% for typical oil and gas applications. Additional installation benefits include reduced right of way requirements, reduced safety hazards, and reduced environmental impact. For applications which corrode steel, the additional corrosion resistance benefits of RTP are extremely compelling. The cost of constructing pipelines has been steadily increasing in past years due to many factors including the rising cost of steel and limited availability of skilled labor. There continues to be a desire to tie in new gas wells faster due to limited construction timeframes. Pipeline corrosion is a major problem for the industry. RTP provides solutions to all of these challenges.

Abstract:
El reciclaje profundo de pavimentos flexibles con cemento Portland es una técnica de recuperación estructural y funcional recurrente en la práctica vial Brasilera, ya que la reutilización de capas degradadas de revestimiento asfáltico o RAP (reclaimed asphalt pavement) y de base, permite reducir costos y tiempo de ejecución. Sin embargo, en Brasil no existe un criterio de dimensionamiento de pavimentos que considere este tipo de materiales. En este sentido, es aceptado que la capacidad estructural de capas cementadas es limitada por la deformación de tracción en su base. Con el objetivo de establecer esta relación, a través de modelos de fatiga, fue desarrollado un programa experimental basado en la experiencia australiana, buscando verificar su aplicabilidad a materiales reciclados de origen brasilero. Conforme al protocolo adoptado, el programa consistió de ensayos de flexión estáticos y dinámicos del tipo cuatro puntos en vigas, con edades de cura mayores a 28 días, moldadas en laboratorio usando energía de compactación modificada brasilera. Las mezclas consideradas están constituidas 4 % de cemento Portland, y por brita granular y RAP en proporciones 80:20, 50:50 y 30:70. El comportamiento mecánico fue evaluado a través de la Resistencia a la Tracción a la Flexión (RTF) y el Módulo Flexural Estático y Resiliente (MFE y MFR, respectivamente). Entre otras conclusiones, el comportamiento estático indica que el incremento de RAP reduce el MFE, incrementando la deformación de tracción de ruptura, mientras que la influencia del RAP en la RTF no fue notoria. De otra parte, la relación entre el exponente de daño y el porcentaje de RAP apunta a una dependencia del fenómeno de fatiga y el contenido de material reciclado. En general, puede concluirse que el protocolo australiano puede ser usado como modelo para el desarrollo de un método brasilero para este tipo de mezclas, con algunas modificaciones.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3486

Abstract:
Rapid thermal processing (RTP) provides a way to rapidly heat substrates to an elevated temperature to perform relatively short duration processes, typically less than 2–3 minutes long. RTP can be utilized to minimize the process cycle time without compromising process uniformity, thus eliminating a bottleneck in CuIn1-xGaxSe2-ySy (CIGSS) module fabrication. Some approaches have been able to realize solar cells with conversion efficiencies close or equal to those for conventionally processed solar cells with similar device structures. Florida Solar Energy Center (FSEC) PV Materials Lab has developed excellent facilities for the preparation of CIGSS thin-film solar cells. A RTP reactor for preparation of CIGSS thin films on 10 cm × 10 cm substrates has been designed, assembled and tested at the FSEC PV Materials Lab. This paper describes the synthesis and characterization of CIGSS thin-film solar cells by RTP technique. Materials characterization of these films was done by SEM, XEDS, XRD, AES, EPMA and electrical characterization was done by current-voltage measurements on soda lime glass substrates by RTP technique. Encouraging results were obtained during the first few experimental sets, demonstrating that reasonable solar cell efficiencies (up to 9%) can be achieved with relatively shorter cycle times, lower thermal budgets and without using toxic gases.

Full text
Abstract:
The term Reclaimed Asphalt Pavement (RAP) is used to designate a material obtained from the removal of pavement materials. RAP is used across the US in multiple applications, largely on asphalt pavement layers. RAP can be described as a uniform granular non-plastic material, with a very low percentage of fines. It is formed by aggregate coated with a thin layer of asphalt. It is often used mixed with other granular materials. The addition of RAP to aggregates decreases the maximum dry unit weight of the mixture and decreases the optimum water content. It also increases the Resilient Modulus of the blend but decreases permeability. RAP can be used safely, as it does not pose any environmental concerns. The most important disadvantage of RAP is that it displays significant creep. It seems that this is caused by the presence of the asphaltic layer coating the aggregate. Creep increases with pressure and with temperature and decreases with the degree of compaction. Creep can be mitigated by either blending RAP with aggregate or by stabilization with chemical compounds. Fly ash and cement have shown to decrease, albeit not eliminate, the amount of creep. Mechanical stabilizing agents such as geotextiles may also be used.

Abstract:
Access to books is key to learning to read and sustaining a love of reading. Yet many low- and middle-income countries struggle to provide their students with reading materials of sufficient quality and quantity. Since 2008, RTI International has provided technical assistance in early reading assessment and instruction to ministries of education in dozens of low- and middle-income countries. The central objective of many of these programs has been to improve learning outcomes—in particular, reading—for students in the early grades of primary school. Under these programs, RTI has partnered with ministry staff to produce and distribute evidence-based instructional materials at a regional or national scale, in quantities that increase the likelihood that children will have ample opportunities to practice reading skills, and at a cost that can be sustained in the long term by the education system. In this paper, we seek to capture the practices RTI has developed and refined over the last decade, particularly in response to the challenges inherent in contexts with high linguistic diversity and low operational capacity for producing and distributing instructional materials. These practices constitute our approach to developing and producing instructional materials for early grade literacy. We also touch upon effective planning for printing and distribution procurement, but we do not consider the printing and distribution processes in depth in this paper. We expect this volume will be useful for donors, policymakers, and practitioners interested in improving access to cost-effective, high-quality teaching and learning materials for the early grades.

Full text
Abstract:
Plastic pollution has become one of the major concerns in the world. Plastic waste is not biodegradable, which makes it difficult to manage waste plastic pollution. Recycling and reusing waste plastic is an effective way to manage plastic pollution. Because of the huge quantity of waste plastic released into the world, industries requiring a large amount of material, like the pavement industry, can reuse some of this mammoth volume of waste plastics. Similarly, the use of reclaimed asphalt pavement (RAP) has also become common practice to ensure sustainability. The use of recycled waste plastics and RAP in HMA mix can save material costs and conserve many pavement industries’ resources. To successfully modify HMA with RAP and waste plastic, the modified HMA should exhibit similar or better performance compared to conventional HMA. In this study, recycled waste plastic, linear low-density polyethylene (LLDPE), and RAP were added to conventional HMA, separately and together. The mechanical properties of conventional and modified HMA were examined and compared. The fatigue cracking resistance was measured with the IDEAL Cracking (IDEAL CT) test, and the Hamburg Wheel Tracking (HWT) test was conducted to investigate the rutting resistance of compacted HMA samples. The IDEAL CT test results showed that the cracking resistance was similar across plastic modified HMA and conventional HMA containing virgin aggregates. However, when 20% RAP aggregates were used in the HMA mix, the fatigue cracking resistance was found to be significantly lower in plastic modified HMA compared to conventional HMA. The rutting resistance from the HWT test at 20,000 passes was found to be similar in all conventional and modified HMA.

Full text
Abstract:
This report presents the results of RTI International Education’s study on teachers' guides across 13 countries and 19 projects. Using quantitative and qualitative methods, we examine how teachers’ guides across the projects differ and find substantial variation in the design and structure of the documents. We develop a scripting index so that the scripting levels of the guides can be compared across projects. The impact results of the programs that use teachers’ guides show significant impacts on learning outcomes, associated with approximately an additional half year of learning, showing that structured teachers’ guides contribute to improved learning outcomes. During observations, we find that teachers make a variety of changes in their classroom instruction from how the guides are written, showing that the utilization of structured teachers’ guides do not create robotic teachers unable to use their own professional skills to teach children. Unfortunately, many changes that teachers make reduce the amount of group work and interactivity that was described in the guides, suggesting that programs should encourage teachers to more heavily utilize the instructional routines designed in the guide. The report includes a set of research-based guidelines that material developers can use to develop teachers’ guides that will support effective instructional practices and help improve learning outcomes. The key takeaway from the report is that structured teachers' guides improve learning outcomes, but that overly scripted teachers' guides are somewhat less effective than simplified teachers' guides that give specific guidance to the teacher but are not written word for word for each lesson in the guide.
