Abstract Europa is a premier target for advancing both planetary science and astrobiology, as well as for opening a new window into the burgeoning field of comparative oceanography. The potentially habitable subsurface ocean of Europa may harbor life, and the globally young and comparatively thin ice shell of Europa may contain biosignatures that are readily accessible to a surface lander. Europa’s icy shell also offers the opportunity to study tectonics and geologic cycles across a range of mechanisms and compositions. Here we detail the goals and mission architecture of the Europa Lander mission concept, as developed from 2015 through 2020. The science was developed by the 2016 Europa Lander Science Definition Team (SDT), and the mission architecture was developed by the preproject engineering team, in close collaboration with the SDT. In 2017 and 2018, the mission concept passed its mission concept review and delta-mission concept review, respectively. Since that time, the preproject has been advancing the technologies, and developing the hardware and software, needed to retire risks associated with technology, science, cost, and schedule.

Human exploration of the Moon is associated with substantial risks to astronauts from space radiation. On the surface of the Moon, this consists of the chronic exposure to galactic cosmic rays and sporadic solar particle events. The interaction of this radiation field with the lunar soil leads to a third component that consists of neutral particles, i.e., neutrons and gamma radiation. The Lunar Lander Neutrons and Dosimetry experiment aboard China’s Chang’E 4 lander has made the first ever measurements of the radiation exposure to both charged and neutral particles on the lunar surface. We measured an average total absorbed dose rate in silicon of 13.2 ± 1 μGy/hour and a neutral particle dose rate of 3.1 ± 0.5 μGy/hour.

In the task of lunar soil collection, estimating the volume of the collected soil is an important part of the sampling control of the lander. Due to the design constraints of the lander, there is no additional installation position for volume measurement equipment. To fully use the sensors already installed, a collected soil volume measurement method is designed in this paper based only on a single monitoring camera. This method uses a sequence of images of the collection area captured by the camera mounted on the acquisition arm to accurately reconstruct the terrain of the collection area surface before and after soil acquisition. Additionally, bi-temporal dense point clouds are reconstructed. Based on the area of change associated with soil collection, the constructed dense point clouds are compared according to the topographic characteristics of the area to estimate the volume of soil collected. Experiments show that the method is stable and reliable and can meet the requirements of actual measurement tasks.

Abstract. Studies on the impacts of climate change typically focus on changes to mean conditions. However, animals live in temporally variable environments that give rise to different exposure histories that can potentially affect their sensitivities to climate change. Ocean deoxygenation has been observed in nearshore, upper-slope depths in the Southern California Bight, but how these changes compare to the magnitude of natural O2 variability experienced by seafloor communities at short timescales is largely unknown. We developed a low-cost and spatially flexible approach for studying nearshore, deep-sea ecosystems and monitoring deepwater oxygen variability and benthic community responses. Using a novel, autonomous, hand-deployable Nanolander® with an SBE MicroCAT and camera system, high-frequency environmental (O2, T, estimated pH) and seafloor community data were collected at depths between 100 and 400 m off San Diego, CA, to characterize timescales of natural environmental variability, changes in O2 variability with depth, and community responses to O2 variability. Oxygen variability was strongly linked to tidal processes, and contrary to expectation, oxygen variability did not decline linearly with depth. Depths of 200 and 400 m showed especially high O2 variability; these conditions may give rise to greater community resilience to deoxygenation stress by exposing animals to periods of reprieve during higher O2 conditions and invoking physiological acclimation during low O2 conditions at daily and weekly timescales. Despite experiencing high O2 variability, seafloor communities showed limited responses to changing conditions at these shorter timescales. Over 5-month timescales, some differences in seafloor communities may have been related to seasonal changes in the O2 regime. Overall, we found lower-oxygen conditions to be associated with a transition from fish-dominated to invertebrate-dominated communities, suggesting this taxonomic shift may be a useful ecological indicator of hypoxia. Due to their small size and ease of use with small boats, hand-deployable Nanolanders can serve as a powerful capacity-building tool in data-poor regions for characterizing environmental variability and examining seafloor community sensitivity to climate-driven changes.

To support the increasing number of planned lunar missions, a collaborative international initiative is underway to conceptualise and establish a lunar satellite constellation for communication and navigation. In this context, the goal of the current paper is to analyse what the obtainable performance is for a lunar lander that executes state estimation employing one-way ranging signals from such a Lunar Navigation Service (LNS). In particular, a small-sized optimised navigation constellation is considered as the main source of measurements, which, coupled with an accelerometer and an altimeter, is used to estimate the lander absolute trajectory during the main braking phase. The guidance is extracted on board by interpolation of a ground-optimised trajectory, followed by a reference-tracking regulator. Two alternative control tuning cases are presented, one targeting high performance, the other targeting low propellant mass. Nominal performance and associated sensitivity analyses assessed the feasibility of supporting such a critical phase with a reduced LNS constellation, reaching final control errors below 500m, with the better performing one going down to 56m. Among the two proposed alternatives, the one targeting low fuel expenditure has proven, however, to also be more robust against time and state uncertainty, providing much larger success rates.

Variegation in Vitis hybrids was investigated to confirm the inheritance as a single, recessive gene as previously proposed and commonly observed in breeding programs. Variegated leaves have ornamental appeal, but the phenotype is sublethal in some environments. Twenty-nine grape families were characterized for variegation including F1, S1, and S2 populations. The majority segregated 3 wild type (WT):1 variegated and were supported by chi-square tests. Four populations had segregation ratios supporting 15:1 or 1:1 models, and a unique flecking phenotype was identified in a Landot 4511 S1 population that suggested the interaction of two recessive loci. A variegated parent was selfed to produce progeny with no WT offspring and was segregated 0:1. Marker trait associations including bulk segregant analysis (BSA), genome-wide association mapping, and quantitative trait loci (QTL) mapping was used on three populations. On chromosome 14, Lvar1 was identified and mapped to 24.5 to 29.5 Mb and associated closely with rhAmpSeq marker 14_27607541. Lvar2 was associated with rhAmpSeq marker 11_18433819 on chromosome 11 at 12.2 to 18.4 Mb. The identification of two loci and the segregation data in some populations suggest that grape breeding germplasm segregates for two recessive loci. The pedigree records suggest that ‘Frontenac’ inherited one of these loci, and that Landot 4511, an ancestor of many populations tested in this experiment, may carry two loci. A total of 252 candidate genes were identified at these loci, including a key target—adenosine triphosphate (ATP)-dependent zinc metalloprotease FtsH6, involved in photosystem II and similar to the var2 mutant in Arabidopsis. This knowledge can help breeders select for ornamental grapevines or eliminate variegation from their breeding programs.

Abstract. Age–depth relationships are the key elements in paleoenvironmental studies to place proxy measurements into a temporal context. However, potential influencing factors of the available radiocarbon data and the associated modeling process can cause serious divergences of age–depth relationships from true chronologies, which is particularly challenging for paleolimnological studies in Arctic regions. This paper provides geoscientists with a tool-assisted approach to compare outputs from age–depth modeling systems and to strengthen the robustness of age–depth relationships. We primarily focused on the development of age determination data from a data collection of high-latitude lake systems (50 to 90∘ N, 55 sediment cores, and a total of 602 dating points). Our approach used five age–depth modeling systems (Bacon, Bchron, clam, hamstr, Undatable) that we linked through a multi-language Jupyter Notebook called LANDO (“Linked age and depth modeling”). Within LANDO we implemented a pipeline from data integration to model comparison to allow users to investigate the outputs of the modeling systems. In this paper, we focused on highlighting three different case studies: comparing multiple modeling systems for one sediment core with a continuously deposited succession of dating points (CS1), for one sediment core with scattered dating points (CS2), and for multiple sediment cores (CS3). For the first case study (CS1), we showed how we facilitate the output data from all modeling systems to create an ensemble age–depth model. In the special case of scattered dating points (CS2), we introduced an adapted method that uses independent proxy data to assess the performance of each modeling system in representing lithological changes. Based on this evaluation, we reproduced the characteristics of an existing age–depth model (Lake Ilirney, EN18208) without removing age determination data. For multiple sediment cores (CS3) we found that when considering the Pleistocene–Holocene transition, the main regime changes in sedimentation rates do not occur synchronously for all lakes. We linked this behavior to the uncertainty within the dating and modeling process, as well as the local variability in catchment settings affecting the accumulation rates of the sediment cores within the collection near the glacial–interglacial transition.

This study aims to identify and analyze production costs in order to determine the seling price of the”Tofu Maju Lancar” product. The method utilized is the cost pluspricing approach with the full costing method, ensuring that the selling price is set effectively to generate optimal profits. This research employs a qualitative approach and utilizes descriptive research techniques. The focal point of this research is the company “Tofu Maju Lancar”, which operates as a tofu producer. The primary objective of this study is to gather pertinen data concerning production costs. The focus of this research encompasses the costs associated with the entire production process. The findings of this study indicate that while the cost plus pricing method using UMKM calculations does yield profits, the home industry is unable to attain the anticipated 50% profits due to generated profits remaining insufficient to cover the factory overhead costs that must be shouldered.

In this thesis, we propose an experimental setup for the study of Landau quantization and associated effects in a two-dimensional ultracold atomic gas. Gauge fields can emerge in the equation of motion for the optically addressed ultracold atoms. To this end, spatially dependent dark states are necessary for the internal states of the atoms. A tripod level scheme yields two degenerate dark states which can leads to either an Abelian U(1) U(1) gauge field or a non-Abelian SU(2) gauge field. Using a suitable laser configuration, we obtain a uniform U(1) U(1) magnetic field which causes the atoms organize themselves in Landau levels. The strength of the effective magnetic field depends on the relative intensity of the lasers beams at the atomic cloud. We estimate the degeneracy of the energy levels for an atomic gas formed by atoms of 87Rb. In addition, we establish the experimental conditions to reach the lowest Landau level regime. In the zero-temperature limit, we realize the emergence of magnetic oscillations in the atomic energy and its derivative as function of the inverse of the effective magnetic field (de Haas van Alphen effect). The period of the de Haas van Alphen oscillation allow us to determine area of the Fermi circle for the atomic gas via an Onsager-like relation. We also show that detuning the a laser from the two-photon resonance we generate a parabolic scalar potential that laterally confines the atoms. As a consequence, the Landau levels degeneracy is removed, since the energy spectrum depends explicitly on the transverse atomic momentum. We show that the Landau levels presents a reminiscent degeneracy when the boundaries conditions are considered. The residual degeneracy occurs when different energy levels overlap. We map the residual degeneracy points as a function of the effective magnetic field. Finally, we present an experimental scheme for observing the spin Hall effect for ultracold atoms in a tripod configuration.
Nesta tese, propomos um arranjo experimental para o estudo da quantização de Landau e efeitos associados em um gás atômico ultrafrio bidimensional. Campos de calibre podem surgir na equação de movimento para átomos ultrafrios oticamente vestidos. Para que isto ocorra, estados escuros espacialmente dependentes são necessários a partir dos estados internos dos átomos. Átomos numa configuração de níveis de energia do tipo tripod produzem dois estados escuros degenerados, que podem levar a campos de calibre Abelianos U(1) U(1) ou não-Abelianos SU(2). Utilizando uma configuração adequada de lasers, mostramos que é possível se produzir um campo magnético sintético uniforme U(1) U(1) que atua nos átomos neutros fazendo-os se organizarem em níveis de Landau. A intensidade do campo efetivo depende da intensidade relativa dos feixes de luz na nuvem atômica. Estimamos a degenerescência dos níveis de energia para um gás atômico formado por átomos de 87Rb e estabelecemos as condições experimentais para que seja atingido o regime em que todos os átomos populam unicamente o nível de Landau menos energético. Considerando o limite de temperatura nula, verificamos o surgimento de oscilações magnéticas na energia e em sua derivada como uma função do inverso do campo magnético efetivo (efeito de Haas van Alphen). O período da oscilação magnética nos permite determinar a área do círculo de Fermi para o gás atômico através de uma expressão similar a de Onsager para sistemas eletrônicos. Mostramos também que dessintonizando um dos lasers em relação à ressonância de dois fótons geramos um potencial escalar parabólico que faz com os átomos sejam lateralmente confinados. Isto resulta na remoção da degenerescência dos níveis de Landau, uma vez que a energia depende explicitamente do momento atômico transverso. Demonstramos que, aplicando condições periódicas de contorno ao sistema, temos o surgimento de uma degenerescência residual. A degenerescência remanescente ocorre quando diferentes níveis de energia se superpõem. Mapeamos os pontos de degenerescência como uma função do campo magnético efetivo. Por fim, apresentamos um esquema experimental para a observação do efeito spin Hall para átomos ultrafrios em uma configuração tripod.

After giving a brief background on the subject we introduce in section two the Phase-Integral Method of Fröman & Fröman in terms of the platform function of Yngve and Thidé. In section three we derive a different form of the radial Bohr-Sommerfeld condition in terms of the apsidal angle of the corresponding classical motion. Using the derived expression, we then show how easily one can calculate the exact energy eigenvalues of the hydrogen atom and the isotropic three-dimensional harmonic oscillator, we also derive an expression for higher order quantization condition. In section four we derive an expression for the angular frequencies of a restricted (0≤φ≤β) soap bubble and also give a proposition concerning the parameters l and m of the associated Legendre differential equation.

We first prove the Local Torelli Theorem for Landau-Ginzburg models. Next, under several conditions, we prove that there is a Frobenius manifold without metric and Euler field, associated to the universal parameter space of Landau-Ginzburg models. We prove these assumptions hold true for every nondegenerate Laurent polynomial whose support polytope is a smooth.

Annotation:
The multiferroic perovskite solid solution xBiFeO3-(1-x)PbTiO3 (BF-PT) exhibits very unique features such as giant tetragonality (c/a ~ 1.19), coexistence of ferroelectric and magnetic order (in certain composition range) and a high Curie point. The system has an added advantage of being semiconducting in nature with an optical band gap of ~ 2 eV which makes it interesting from the viewpoint of photocatalyst and photovoltaic applications. The end members BiFeO3 and PbTiO3 show rhombohedral (R3c) and tetragonal (P4mm) structures, respectively. The system is reported to exhibit morphotropic phase boundary (MPB) separating the rhombohedral and tetragonal phases near x ~ 0.73. Despite considerable research, the morphotropic phase boundary (MPB) region characterized by the coexistence of coexistence of the tetragonal and rhombohedral phases, is still an unresolved issue. In this work we have examined (i) the factors that leads to the uncertainty in the MPB region of this system, (ii) the pressure induced structural transformation behavior of the tetragonal compositions, (iii) photocatalytic performance of the different phases, and finally (iv) an extensive study on the ferroelectric, piezoelectric and high-field electrostrain behavior of La-modified BF-PT. The thesis has seven chapters. Chapter 1 presents the fundamental concepts and definitions which are relevant to understand the results presented in the thesis. It also contains a summary of the literature pertaining to BiFeO3 and its various derivatives. Chapter 2 explains the details of the experimental methodology and analysis used in this work. The main results of the thesis are presented in the next four chapters (3-6). Chapter 3 deals with the erratic phase formation behavior in a wide range of compositions in (1-x)BiFeO3-(x)PbTiO3 (BF-PT) system in a certain composition range, often referred to as the MPB region. Under similar sintering conditions, sometimes the pellets would spontaneously disintegrate to powder (completely/partially) after cooling and sometimes not. Structural analysis revealed that the disintegrated powder was invariably tetragonal (P4mm) phase and the pellet which survives exhibit coexistence of P4mm and R3c phases. Detailed microstructural investigation revealed that this different in the phase formation behavior is intimately related to the size of the grains. For the composition x=0.29, a composition within the reported MPB region of this system, the spontaneously disintegrated powder grains exhibit size of ~ 10 microns. When the size of the grains was reduced to ~ 0.5 μm by mechanical grinding, the same powder specimen shows a rhombohedral (R3c) phase after annealing at ~ 700 oC (annealing was done to get rid of the residual stress induced effect during the grinding process, if any). Neutron diffraction experiment revealed that the size induced rhombohedral phase is also antiferromagnetic in nature. This suggests a strong coupling of the antiferromagnetic phase with the rhombohedral (R3c) structure. Based on the structural results, we argue that the driving force for this size driven coupled inter-ferroelectric-magnetic transformation is the large depolarizing and the stress fields due to large polarization and domain walls energy (which are intimately related to the giant tetragonality). Chapter 4 is an extension of the findings reported in Chapter 3. Keeping in view the fact that BiFeO3 and its derivatives are semiconducting ferroelectric with a band gap of ~ 2 eV, we investigated the behavior of the different phases (tetragonal and rhombohedral) regarding their photocatalytic properties. As discussed in Chapter 3, reducing the size of the grains to below 0.5 micron switches the ground state from tetragonal to rhombohedral. But then this was possible only after the ground specimen was annealed above the Curie point, i.e. after taking the system to the paraelectric state. When the annealing was not done, the as-ground 0.5 micron grains still retained the tetragonal phase. The pinned tetragonal domain walls which are already present in the large grains act as barriers for the bulk tetragonal regions to transform to rhombohedral when the size is reduced physically at room temperature. By taking the system to the paraelectric phase, the tetragonal domain walls are “dissolved”. In the absence of the tetragonal domain wall as barriers, the system lands in the rhombohedral (R3c) ground state during cooling. The trapped tetragonal phase at room temperature in the 0.5 microns grains are therefore metastable in nature. We therefore had the opportunity to examine the catalytic performance of the same powder in its stable rhombohedral phase (obtained after annealing) and metastable tetragonal phase (before annealing). For the sake of reference, we also made compositions with stable tetragonal phase (with grains having the same specific area as the metastable tetragonal phase). The photocatalysis experiments were carried out using these powders as catalysts to degrade typical organic contaminants. We found that when the metastable phase was used as the catalyst, the rate of die degradation increased by nearly five times as compared to its stable phase counterparts. Our results suggest that the metastable ferroelectric phase either increase the availability of the photogenerated charge carriers to participate in the redox reaction associated with dye degradation or increase the adsorption rate of the dyes on the surface of the particles. Chapter 5 gives the details of the investigation pertaining to pressure induced structural transformations in the tetragonal phase of (x)BiFeO3-(1-x)PbTiO3. High pressure experiments were carried out using complementary Raman and x-ray diffraction techniques to capture the structural changes on both the local and global length scales. We found two different types of pressure induced phase transformations in two different composition ranges. We established a correlation of the transition pressure with the tetragonality of the parent phase at the ambient pressure and temperature conditions. While the compositions (x < 0.4) with relatively low tetragonality show a transition from tetragonal P4mm to a non-polar rhombohedral R3̅c phase, the compositions in the range 0.4 < x < 0.71 with a relatively high tetragonality undergo a transformation first to polar rhombohedral (R3c) phase before transforming to the non-polar R3̅c phase. The transition pressure at which the composition loses its tetragonal structure decreases with the increasing BF content. Our study confirmed that the MPB at room temperature can be stabilized even by pressure in tetragonal systems with large tetragonality. Chapter 6 reports the discovery of an extraordinary large electrostrain (~ 1.3%) in polycrystalline specimens of La modified BF-PT, more specifically in the system with chemical formula 0.55(Bi0.7La0.3)FeO3-0.45PbTiO3. This is the largest electrostrain value reported so far in a polycrystalline ceramic specimen. We carried out a detailed investigation to understand the mechanism associated with this ultrahigh electrostrain response using Raman, XRD, neutron powder diffraction, and electron microscopy with specimen subjected to poling field. We found that the composition y = 0.30 exhibiting the ultrahigh electrostrain exhibit a cubic-like structure in the unpoled state. On poling it transforms to a majority tetragonal phase. Neutron diffraction revealed very weak superlattice reflections, characteristic of antiphase tilted octahedra in both the unpoled and poled specimen. Detailed analysis using group theoretical ideas and Rietveld analysis of the neutron diffraction data, revealed that the true structure of this system is monoclinic (space group Cc) although the pseudocubic lattice parameters are tetragonal-like. Raman and electron microscopic studies revealed that what appears as a cubic-like to tetragonal-like transformation on application of the poling field is primarily a manifestation of increase in the coherence length of the tetragonal-like domains. This composition behaves as a relaxor ferroelectric and the HAADF-STEM analysis revealed that the cubic—like phase is associated with the presence of considerable positional disorder, the degree of which is noticeably reduced after poling. An extensive XRD study in-situ with electric field was also carried out to understand the domain switching behavior with field. This study proved that the ultrahigh electrostrain of the critical composition (y = 0.30) is primarily associated with (i) the large reverse switching of the tetragonal-like non-180o ferroelectric-ferroelastic domain walls and (ii) the large tetragonality (c/a ~ 1.23) of the tetragonal-like phase. The important results of the thesis and the scope for further studies are summarized in Chapter 7.

AbstractThere are three approaches to defining the potential instability zonation of natural slopes. The first approach is to understand the failure mechanism through soil properties in a slope, and the mechanisms of failure and movement. The second approach aims to understand the tendency of slopes to fail, with terrain factors that form the essential characteristics of slopes. Understanding the spatial distribution of slope failures and their patterns on a particular slope is the third approach and the focus of this research. All approaches require field verification with expert knowledge.Slope failure zones contain unique topographic patterns that can be used to identify the failure shape and its dimensions. Slope failures are one of many natural denudation processes. Most slope failure landform units, considered as past slope failures tend to expand naturally. If there is no human involvement, zones of past natural slope failure can be also categorized as potential zones of future slope failure. The large-scale geomorphological analysis is the best approach for clearly identifying landform units associated with potential zones of slope failures. The best scale is 1:10,000. Two-dimensional or three-dimensional raster interpretation of slopes can be used to visualize more clearly the actual shape of slope failures. For the study, raster geomorphological mapping uses LiDAR survey data to characterize the landform units of slope failures and to prepare a landslide susceptibility evaluation.

AbstractTraveling on a mountainous road is attractive but questionable under aggressive climatic conditions such as extreme rainstorms. Roads are often designed in different geological complexity overlaying upper and lower terrains. The complexity of slope geometries, potential deformities, ground discontinuities, soil-rock composite nature, factors incorporated in structural integrity, the complexity associated with infrastructure developments, and unstable landform have long been causes of the increasing cost of road constructions in hills. In many instances, landform geometries and the natures of slope observed in-situ allow us to understand many salient features that we need to know in the design to mitigate landslide threats. The extent to which we make the collective effort to gather many features of landforms and their static representations concludes its validity. Findings are more forced to be based on geometrical evidence of slopes and cross-checked with an appropriate design criterion. A provision should describe a design or construction method that is deemed to comply with the site-specific conditions. Such an approach will save the enormous cost of investigations, design, and simplification for numerical evaluations, and also contribute to an indirect approach to road restoration and improve an appropriate approach for resilience to landslide hazards.

For the past decade, World Wildlife Fund Canada has been at the leading edge of GIS mapping initiatives and gap analyses regarding the establishment of protected areas across Canada’s lands and waters. In the Northwest Territories (NWT), we have led an open, multi-stakeholder exercise this past year to compile and digitise all existing bio-physical and cultural information for the Mackenzie Valley and NWT to produce high-quality readily available GIS maps showing the regional distribution of these values. These data will be available to all interested stakeholders to highlight information gaps and to consider the placement of pipeline related developments. Furthermore, consistent with the NWT Protected Areas Strategy (PAS) [1], communities and other groups can use the information to assist in identifying areas of high natural and cultural value which should be reserved for protection as pipeline development plans and approvals are being made. Based on these data, a defensible network of protected areas representing the diversity of landform features in the Mackenzie Valley natural regions can be established to provide all parties with greater certainty and confidence as the development proceeds. This poster shows some key preliminary results from this mapping project, describes the various data layers and analytical techniques used, and highlights spatial examples where pipeline routing, associated infrastructure and conservation/protected areas in affected natural regions could all be achieved and widely supported.

The article discusses the use of former agricultural lands for afforestation. The fertility of these lands is reduced, low biological activity of soils is noted, the content of substances inhibiting the growth of woody plants is observed. The presence of a compacted subsurface layer contributes to the fact that the root systems of trees are formed by surface and do not reach groundwater. Created forest plantations usually experience a water supply crisis, they die off in dry years, they are easily exposed to diseases and pests. Possible ways of solving problems associated with afforestation in this category of land are suggested.

A methodology is presented to allow designers to estimate the penalty for turbine efficiency associated with film cooling. The approach is based on the control volume analysis of Hartsel and the entropy-based formulations of Young and Wilcock. The present work extends these techniques to include flow ejected at compound angles and uses three-dimensional CFD to provide the mainstream flow properties. The method allows the loss contribution from each hole to be identified separately. The proposed method is applied to an aeroengine high-pressure turbine stage. It is found that, if the efficiency definition includes all irreversibilities, the penalty associated with film cooling would be 8.0%. However, if the pragmatic approach is adopted whereby the unavoidable entropy generated due to the equilibration of coolant and mainstream static temperatures is ignored, the efficiency penalty is 0.7%. Finally, a series of case studies is used to quantify the impact of changes to the local mainstream flow direction and coolant ejection angle on the predicted turbine efficiency. It is shown, quantitatively, that reducing the angle between the directions of the coolant and mainstream flows offers the greatest potential for the designer to improve film cooled turbine efficiency.

Nearly 499,000 motor vehicle crashes involving trucks were reported across the United States in 2018, out of which 22% resulted in fatalities and injuries. Given the growing economy and demand for trucking in the future, it is crucial to identify the risk factors to understand where, when, and why the likelihood of getting involved in a severe or moderate injury crash with a truck is higher. This research, therefore, focuses on capturing and exploring risk factors associated with surrounding land use and demographic characteristics in addition to crash, driver, and on-network characteristics by modeling injury severity of crashes involving trucks. Crash data for Mecklenburg County in North Carolina from 2013 to 2017 was used to develop partial proportionality odds model and identify risk factors influencing injury severity of crashes involving trucks. The findings from this research indicate that dark lighting condition, inclement weather condition, the presence of double yellow or no-passing zone, road sections with speed limit >40 mph and curves, and driver fatigue, impairment, and inattention have a significant influence on injury severity of crashes involving trucks. These outcomes indicate the need for effective geometric design and improved visibility to reduce the injury severity of crashes involving trucks. The likelihood of getting involved in a crash with a truck is also high in areas with high employment, government, light commercial, and light industrial land uses. The findings can be used to proactively plan and prioritize the allocation of resources to improve safety of transportation system users in these areas.

Digital Promise and Langer Research Associates developed the “Survey of Student Perceptions of Remote Teaching and Learning” to capture the experiences of undergraduates taking courses that transitioned to online instruction in response to the COVID-19 pandemic. The survey explores the nature of college courses as they were taught during the COVID-19 outbreak, the pervasiveness of various challenges undergraduates faced after the transition to remote instruction, and course features associated with higher levels of student satisfaction. Data analyses compared experiences of students from low-income, underrepresented, or rural backgrounds to those of students with none of these characteristics. This survey was administered in the spring of 2020 to a random national sample of 1,008 undergraduates, age 18 and older, who were taking college courses for credit that included in-person class sessions when the COVID-19 pandemic hit and had to finish the course by learning at a distance.

Countries globally are committing to achieve future greenhouse gas emissions reductions to address our changing climate, as outlined in the Paris Agreement from the United Nations Framework Convention on Climate Change (UNFCCC) Conference of the Parties. These commitments, called nationally determined contributions (NDCs), are based on projected anthropogenic greenhouse gas (GHG) emissions levels across all sectors of the economy, including land use, land use change, and forestry (LULUCF) activities. Projecting LULUCF emissions is uniquely challenging, and the uncertainty of future LULUCF emissions could require additional mitigation efforts in the land use sectors to reduce the risk of NDC noncompliance. The objectives of this paper are to provide critical information on what forest sector mitigation activities are currently underway in the United States on private lands, review recent literature estimates of the mitigation potential from these activities (and associated economic costs), identify gaps in the literature where additional analytical work is needed, and provide recommendations for targeted mitigation strategies should US emissions approach or exceed targeted post-2020 NDC levels.

Der volle Inhalt der Quelle
Annotation:
This paper introduces a general framework for analyzing the impacts of regional and global technological change on long run agricultural output, prices, land rents, land use, and associated GHG emissions. In so doing, it facilitates a reconciliation of the apparently conflicting views of the impacts of agricultural productivity growth on global GHG emissions and environmental quality. As has been previously recognized, in the case of a global change in farm productivity, the critical condition for an innovation to lead to diminished land use is that the farm level demand for agricultural products is inelastic. However, in the more common case where the innovation is regional in nature, the necessary condition for a reduction in global land use and associated GHG emissions is more complex and depends on the relative yields, emissions efficiencies and supply conditions in the affected and unaffected regions. While innovations in agricultural are most common land-sparing at global scale, innovations in regions commanding a small share of global production, with relatively low yields, high land supply elasticities and low emissions efficiencies can lead to an increase in global land use change emissions. A numerical example illustrates these points and suggests that these conditions may hold for productivity shocks in Latin America and Sub-Saharan Africa. These insights are also relevant for the emerging literature on the effect of adverse climate change on global agriculture and associated emissions from land use change.

Annotation:
In recent years there has been a flurry of activity aimed at evaluating the land use consequences of biofuels programs and the associated carbon releases. In this paper we argue that these studies have tended to underestimate the ensuing land use emissions, because they have ignored the role of irrigation, and associated constraints on cropland expansion. In this paper, we develop a new general equilibrium model which distinguishes irrigated and rainfed cropping industries at a global scale. Using the new model we evaluate the implications of land use change due to US ethanol programs, in the context of physical constraints on the expansion of irrigated cropland. We find that models which mingle irrigated and rainfed areas underestimate the global land use changes induced due to the US ethanol expansion by about 5.7%. They tend to underestimate the corresponding land use emissions by more than one fifth.
