Domingues, Rita B., Benjamin A. Mosley, Patrícia Nogueira, Inês B. Maia, and Ana B. Barbosa. "Duration, but Not Bottle Volume, Affects Phytoplankton Community Structure and Growth Rates in Microcosm Experiments." Water 15, no. 2 (2023): 372. http://dx.doi.org/10.3390/w15020372.
Full textAbstract:
It is generally assumed that the larger the bottle volume, the longer the duration of phytoplankton microcosm experiments. We hypothesize that volume and duration are independent, as volume does not regulate the extension of the exponential growth phase. We conducted two microcosm experiments using 1, 2, and 8 L bottles, inoculated with phytoplankton collected in the Ria Formosa lagoon (SE Portugal) and incubated for 1, 2, 4, and 8 days. Phytoplankton net growth rates were estimated using chlorophyll a concentration and cell abundance, determined with epifluorescence and inverted microscopy. Results show that the experimental duration significantly affected net growth rates, independently of volume, with decreasing net growth rates with time. Regarding volume, we found significant, but weak, differences in net growth rates, and significant two-way interactions only for the larger-sized cells. No significant differences in net growth rates across the different volumes were detected for the smaller, most abundant taxa and for the whole assemblage. We conclude that duration, not volume, is the main factor to consider in microcosm experiments, and it should allow the measurement of responses during the exponential growth phase, which can be detected through daily sampling throughout the duration of the experiment.

Full textAbstract:
Investigations concerning the influence of pharmacologic agents on transperitoneal water movement are predominantly undertaken in the hope that their results can help in a restoration of net ultrafiltration (UF) volume toward normal in cases with declining UF during long-term dialysis treatment. Net UF volume represents the difference between net transcapillary UF and lymphatic absorption. The choice of a pharmacological agent for enhancing UF depends on the mechanisms responsible for net UF loss, which include: (a) early dissipation of the transperitoneal osmotic gradient; (b) decrease in the peritoneal surface area; (c) Iymphomonokine overproduction; (d) enhanced lymphatic absorption; (e) high residual volumes left in the peritoneal cavity; or (f) a combination of these factors. Leakage of dialysate to the abdominal wall sometimes occurring in peritoneally dialysed patients (1), according to a definition of net UF volume, cannot be regarded as a true UF loss.

Objective To validate the use of a modified three-pore model for predicting fluid transport during long dwell exchanges that use a 7.5% icodextrin solution. Design A nonrandomized, single group, repeated measures study. Patients Ten peritoneal dialysis patients underwent a single 8-hour exchange of a 7.5% icodextrin solution. All patients were naïve to icodextrin. Main Outcome Measures A modified three-pore model was used to model solute and fluid transport during each 8-hour exchange. Concordance correlation coefficients were used to estimate the level of agreement between modeled and measured values of net ultrafiltration (UF) and intraperitoneal volume. Methods Each patient underwent a modified 8-hour standard peritoneal permeability analysis using a 2-L 7.5% icodextrin exchange. Dextran 70 was added to the icodextrin solution as volume marker to estimate fluid transport kinetics. Transcapillary UF, fluid absorption, and intraperitoneal volumes were assessed via the volume marker at 0, 5, 15, 30, 60, 120, 240, 300, 360, 420, and 480 minutes. Results There was strong agreement (concordance correlation = 0.9856) between net UF as measured by the volume marker data and net UF as modeled using the modified three-pore model implemented in PD Adequest (Baxter Healthcare, Deerfield, Illinois, USA). Conclusions Net UF and intraperitoneal volumes for long dwell exchanges using a 7.5% icodextrin solution can be accurately modeled with a modified three-pore model. Steady state icodextrin plasma levels are needed to accurately predict net UF for chronic users of icodextrin.

Hemodilutional anemia has been cited as a contributing factor to red blood cell (RBC) transfusions in cardiac surgery patients. Accordingly, efforts have been made to minimize hemodilution by reducing cardiopulmonary bypass (CPB) prime volume. We sought to assess the impact of these efforts on intraoperative RBC transfusions. We evaluated 21,360 patients undergoing coronary artery bypass with or without aortic valve surgery between July 2011 through December 2016 at any of 42 centers participating in the Perfusion Measures and Outcomes registry. The primary exposure was net CPB prime volume (total prime volume minus retrograde autologous prime volume) indexed to body surface area (mL/m2), which was further divided into quartiles (Q1: <262 mL/m2, Q2: 262–377 mL/m2, Q3: 377–516 mL/m2, and Q4: >516 mL/m2). The primary outcome was intraoperative RBC transfusion. We modeled the effect of index net prime volume on transfusion, adjusting for patient (age, gender, race, diabetes, vascular disease, previous myocardial infarction, ejection fraction, creatinine, preoperative hematocrit (HCT), total albumin, status, aspirin, and antiplatelet agents), procedural (procedure types) characteristics, surgical year, and hospital. The median net prime volume was 378 mL/m2 (25th percentile: 262 mL/m2, 75th percentile: 516 mL/m2). Relative to patients in Q1, patients in Q4 were more likely to be older, female, nondiabetic, have higher ejection fraction, have more ultrafiltration volume removed, and undergo more elective and aortic valve procedures (all p < .05). Patients in Q4 relative to Q1 were exposed to lower nadir HCTs on bypass, p < .05. The net prime volume was associated with an increased risk of transfusion (8.9% in Q1 vs. 22.6% in Q4, p < .001). After adjustment, patients in Q4 (relative to Q1) had a 2.9-fold increased odds (ORadj = 2.9, 95% CI [2.4, 3.4]) of intraoperative RBC transfusion. In this large, multicenter experience, patients exposed to larger net prime volumes were associated with greater adjusted odds of receiving intraoperative transfusions. Our findings reinforce the importance of efforts to reduce the net CPB prime volume. Based on these findings and other supporting evidence, the net prime volume should be adopted as a national quality measure.

Full textAbstract:
Snake (Thamnophis spp.) proximal renal tubules were perfused and bathed in vitro either with medium containing sodium or with medium in which the sodium was replaced with choline. Net fluid absorption was measured by changes in volume marker concentration, and cell volumes and cell membrane surface areas were measured by ultrastructural morphometric methods. Net fluid absorption did not differ significantly in the presence or absence of sodium. However, during the 20-25-min perfusion in the absence of sodium, significant morphological changes took place. The volume of the cells, doubled and the volume of the intercellular spaces nearly quintupled. The areas of the lateral and apical cell membranes approximately doubled, but their surface densities remained essentially constant. Therefore the larger cells in the absence of sodium had proportionally enlarged surface areas, so that the volume-to-surface area ratio remained constant. These morphological changes occurred concomitantly with the maintenance of net fluid absorption and might play a permissive role in such maintenance in the absence of sodium.

Full textAbstract:
ABSTRACT Oil spill response often involves making decisions regarding dispersant usage; the potential tradeoffs of increasing exposure of water column biota to hydrocarbons in order to reduce surface and shoreline oiling needs to be carefully considered and justified. A modeling analysis using RPS ASA's Spill Impact Model Application Package (SIMAP) was performed to evaluate the likely water volume adversely affected by naturally- or chemically-dispersed oil, as well as the surface area impacted by floating oil, and summarized in guidance useful for response planners and decision-makers. Key inputs were varied: oil type, oil volume, environmental (e.g., wind speed, temperature) conditions, dispersant use, weathering state when dispersants are applied, and toxicity to aquatic biota. Model results, including water volume where acute toxic effects would occur and the area of water surface oiled (which would impact wildlife, as well as socioeconomic uses), are summarized in tabular form, as well as a software-tool for interpolation, to provide data for quantitative comparisons of tradeoffs. Findings show that for (effective) dispersant treatment of floating oil volumes up to 100,000 gal in a single location during a short period of time (&lt;1 hr; e.g., by a dispersant plane sortie), the area of surface water where water column biota would be affected would be much less than that affected by floating oil thick enough to directly affect wildlife. Thus, even if large volumes of oil are dispersed, a net environmental benefit may be achieved due to reduction or prevention of exposure to floating and shoreline oil, especially if the dispersant applications are over a wide area or over time.

Full textAbstract:
The size of net cages increases rapidly, reaching volumes above current experience. More exposed locations are used for fish production, introducing higher loads on the net cage and fish farm from strong water currents and large waves. Strength analysis can be a useful tool for development of net-cage designs to avoid escape of fish and ensure sufficient volume for good fish welfare and water quality. The main objectives of this research are to investigate the structural response of modular pontoon collar floating cage due to the current load to support the fish farming activities. Strength analysis was performed using commercial explicit finite element software to calculate the distribution of loads in the net cage due to current, weights and gravity. The net cage was modeled using truss elements that represented several parallel twines. Sub-elements allowed the trusses to buckle in compression, and only negligible compressive forces were seen in the numerical results. Resulting drag loads and cage volume were shown to be dependent on the net cage size and collar shape.

Full textAbstract:
There is a strong need in forging industry to reduce waste of material, improve quality, and reduce cost of forgings. About 30% of the material is wasted during conventional closed-die forging. Therefore, in order to reduce the cost of forged products and to obtain near-net or net shape parts, new forging methods should be applied. Precision forging concept is a cost-effective way to produce net-shape or near-net shape components. In recent years, there has been an increased interest in the production of gears by the net-shape forging technique. This has specific advantages over the traditional manufacturing processes of cutting gears such as hobbing, turning, and grinding including savings on cost and raw material, increased productivity, and gears with higher
dynamic properties than conventionally cut ones.
In this study, precision forging of a particular spur gear has been investigated. The precision forging die set has been conceptually designed and
modeled in a computer aided design environment. The forging process of particular spur gear has been simulated by using a commercially available finite volume program. After the successful simulation results, the prototype die set
and the tube-shaped billets were manufactured. The real-life experiments have been realized by using 1000 tons mechanical forging press available in METUBILTIR
Research and Application Center Forging Laboratory. The results have been compared with the computer simulations. After the real-life experiments, it has been observed that the conceptual die design is appropriate and near-net
shape spur gears are successfully obtained by the proposed precision forging die set.

Full textAbstract:
With the aim for higher economical efficiency, considerable and radical changes have occurred in the worldwide electricity sector since the beginning of 1980s. By that time, the electricity sector has been controlled by the state-owned vertically integrated monopolies which manage and control all generation, transmission, distribution and retail activities and the consumers buy electricity with a price set by these monopolies in that system. After the liberalization and restructuring of the electricity power sector, separation and privatization of these activities have been widely seen. The main purpose is to ensure competition in the market where suppliers and consumers compete with each other to sell or buy electricity from the market and the consumers buy the electricity with a price which is based on competition and determined according to sell and purchase bids given by producers and customers rather than a price set by the government.
Due to increasing competition in the electricity market, accurate electricity price forecasts have become a very vital need for all market participants. Accurate forecast of electricity price can help suppliers to derive their bidding strategy and optimally design their bilateral agreements in order to maximize their profits and hedge against risks. Consumers need accurate price forecasts for deriving their electricity usage and bidding strategy for minimizing their utilization costs.
This thesis presents the determination of system day ahead price (SGOF) at the day ahead market and system marginal price (SMF) at the balancing power market in detail and develops artificial neural network models together with multiple linear regression models to forecast these electricity prices in Turkish electricity market. Also the methods used for price forecasting in the literature are discussed and the comparisons between these methods are presented. A series of historical data from Turkish electricity market is used to understand the characteristics of the market and the necessary input factors which influence the electricity price is determined for creating ANN models for price forecasting in this market. Since the factors influencing SGOF and SMF are different, different ANN models are developed for forecasting these prices. For SGOF forecasting, historical price and load values are enough for accurate forecasting, however, for SMF forecasting the net instruction volume occurred due to real time system imbalances is needed in order to increase the forecasting accuracy.

This diploma thesis deals with the experimental and numerical analysis of volume changes of fine-grained concrete. Experiments were carried out, measuring both the length changes as well as the mass losses and the internal temperature of the test specimens made from fine-grained concrete. The measurements were divided into two parts (phases). The first phase took approx. 72 hours. The second phase was focused on the long-term measurements and will be completed after stabilization of the mass losses and length changes. In the diploma thesis, the first phase of measurement was elaborated in detail, both in terms of experimental and numerical analysis. In addition, a C # .NET program was created to facilitate the processing of raw measurement data from the data logger.

Full textAbstract:
Dans la simulation des arcs électriques, une estimation de la contribution radiative est indispensable pour fournir une description satisfaisante du comportement thermique du plasma. La prédiction précise de la divergence du flux radiatif (DFR) est essentielle pour déterminer l'évolution de la température de l'arc. Afin de décrire avec précision les effets radiatifs, la résolution de l'équation de transfert radiatif (ETR) est nécessaire moyennant la connaissance du coefficient d'absorption du milieu. Malheureusement, ce coefficient étant dépendant de la température et de la longueur d'onde, cette équation s'avère complexe à résoudre et coûteuse en temps de calcul. De nombreuses méthodes approximatives sont ainsi développées pour simplifier le calcul des propriétés radiatives. Dans ce travail, nous décrivons finement le spectre d'un plasma d'air avec près de 7.106 points en fréquence (ou longueur d'onde). A partir de ce découpage, nous calculons la DFR, soit à partir de la méthode approchée du coefficient d'émission nette (CEN) basée sur une simplification géométrique du plasma, soit à partir de coefficients moyens d'absorption (CMA) obtenus après découpage du spectre en 6 intervalles spectraux utilisant différentes moyennes (Classique, Planck, Planck modifiée et Rosseland), soit à partir d'un calcul " exact " correspondant à la résolution directe de l'ETR. Les calculs sont réalisés pour 9 configurations simples en 1D simulant un plasma cylindrique dont la température ne varie qu'en fonction du rayon. Les différentes étapes de calcul y sont présentées mettant en évidence l'influence de certains paramètres comme la largeur et la température maximale du profil de température, la pression, les vapeurs de cuivre .... Une grande partie de ce travail porte sur la comparaison des résultats obtenus par le calcul " exact " avec ceux déduits des différentes méthodes approchées dans le but de valider leur utilisation ainsi que leur précision. Cette comparaison nous a permis de développer une méthodologie d'optimisation apportant des améliorations au calcul des méthodes approchées (CEN et CMA) permettant ainsi une meilleure description du rayonnement. Enfin, ce travail présente le développement d'un modèle d'arc libre 2D axisymétrique résolvant les équations de Navier-Stockes et de Maxwell par la méthode des volumes finis. Celui-ci permet une comparaison entre la méthode du CEN et la méthode P1 qui tient compte de l'absorption du rayonnement des zones froides<br>In the simulation of electrical arc, the representation of radiative contribution is essential to provide a satisfactory description of the thermal behavior of the plasma. The accurate prediction of the radiative emission is essential to determine the evolution of the arc temperature. For a precise description of radiative effect, a resolution of the Radiative Transfer Equation (RTE) , is necessary necessary with knowledge of the absorption coefficient. Unfortunatly, the complexity of this coefficient - dependent on temperature and wavelenghth- makes this equation impossible to solve in term of computational cost. This is why many approximative methods are developed to simplify the calculation of the radiative properties. In this work, we have carried out a detailed description of the spectrum of an air plasma with about 7.106 points on frequency. From this description, we have calculated the divergence of the radiative flux either from the net emission coefficient (NEC) based on a geometric simplification of the plasma, or from the mean absorption coefficients (MAC) calculated after a division of the spectrum into 6 intervals in which we have used different mean functions (Classic, Planck, Planck Modified and Rosseland), or from an exact calculation corresponding to a direct solution of the RTE. This is why many approximative methods were developed to reduce numerical demands . The calculations have been done for 9 simplified configurations in 1D assuming a cylindrical plasma for which the temperature profile varies only with the radius. The different steps of the work are presented and highlight the influence of several parameters such as the temperature profile, the pressure, the copper vapors.... A great part of this work deals with the comparison between the results obtained from the exact resolution with the results deduced from the other approaches in order to validate the use and the accuracy of the different methods. This comparison allowed us to develop an optimization methodology providing improvements to the calculation of the approximate methods (NEC and MAC) allowing a better description of the radiative properties. Finally, this work presents the development of an axisymmetric 2D free-burning arc model solving the Navier-Stockes and Maxwell equations by the finite volume method. This model allows a comparison between the NEC method and the P1 method which takes into account the absorption of radiation in the cold areas

Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 93-94).<br>Airfreight forwarding companies must develop accurate forecasting tools to analyze the suitability and attractiveness of each incoming bidding process, to decide whether to participate in a tender and how to define the optimal commercial strategy. The "1:6" weight/volume ratio establishes that whenever the cargo ratio is different from 1:6 (1m3:167 kg) forwarders must pay the higher rate: either volume or weight. Given the main constraints in terms of volumetric capacity and maximum weight per volumetric unit, the most profitable business opportunities consist of combining in the same load compatible products with different densities. The main target is to come close as possible to the desired 1:6 ratio, to minimize the average price per load. To remain competitive, airfreight forwarding firms must improve their consolidation techniques, to combine in the same load cargo with compatible densities. The availability of robust analytical resources will allow airfreight industry companies to improve their rate of success, in terms of enhancing both efficiency (by increasing air volumes and densities) and profitability (by minimizing the Net Achieved Rate). This thesis develops an analytical model based on meaningful metrics to provide airfreight forwarders with an accurate and solid forecasting tool to select the bids under consideration that best match with their current portfolio in terms of air volume usage for a given origin-destination lane. It also predicts breakeven rates to increase profitability by minimizing the Net Achieved Rate. Furthermore, the model provides a series of metrics and visualization tools to help air freight forwarding companies to improve their understanding of their current portfolio for a given origin-destination lane and define their commercial strategy with respect to air freight cargo tenders.<br>by Per Niklas Blomberg and Ramon Gras Alomá.<br>M.

Full textAbstract:
La malattia policistica renale autosomica dominante (Autosomal Dominant Polycystic Kidney Disease - ADPKD) rappresenta la più comune malattia renale ereditaria ed è causa dell’ultimo stadio della malattia renale (End Stage Renal Desease - ESRD) circa nel 10% dei pazienti. Negli ultimi dieci anni, la velocità di filtrazione glomerulare (Glomerular Filtration Rate - GFR) e la misura della creatinina serica sono stati gli unici biomarker disponibili per monitorare la progressione della malattia nei pazienti con ADPKD. Purtroppo diversi studi hanno evidenziato che i valori di GFR rimangono per anni entro i limiti di normalità, e diventano anomali solo verso gli ultimi stadi della malattia, e la concentrazione di creatinina serica è ottima per valutare la funzionalità, ma non dà alcun tipo di informazione sulle anomalie strutturali del rene. Rimane quindi un’indiscussa necessità di marcatori in grado di monitorare l’effettiva progressione della malattia, la crescita delle cisti e la risposta ai trattamenti farmacologici, disponibili da poco in Italia, fin dai primi stadi del disturbo.
Il volume totale renale (Total Kidney Volume - TKV) è un parametro riconosciuto dal Consortium of Renal Imaging Studies in Polycystic Kidney Disease (CRISP) come valido marker per la diagnosi e la prognosi dell’ADPKD. Tuttavia la relazione che intercorre tra il TKV e la funzionalità renale nei pazienti con ADPKD rimane di difficile comprensione, a causa dei numerosi e contraddittori fattori che caratterizzano la patologia. Inoltre, l’utilizzo del TKV come marker per monitorare la progressione di ADPKD ha sollevato il dubbio su quale sia il modo migliore di misurare il TKV e i cambiamenti al suo interno.
Pertanto, questa tesi si propone di formulare una rassegna aggiornata delle tecniche di imaging che possono essere utilizzate per misurare il TKV nei pazienti con malattia renale policistica, sottolineando le ricadute positive e quelle negative di ogni approccio.

Full textAbstract:
Abstract The superior soft tissue differentiation provided by MRI may enable more accurate tumor segmentation compared to CT and PET, potentially enhancing adaptive radiotherapy treatment planning. The Head and Neck Tumor Segmentation for MR-Guided Applications challenge (HNTSMRG-24) comprises two tasks: segmentation of primary gross tumor volume (GTVp) and metastatic lymph nodes (GTVn) on T2-weighted MRI volumes obtained at (1) pre-radiotherapy (pre-RT) and (2) mid-radiotherapy (mid-RT). The training dataset consists of data from 150 patients, including MRI volumes of pre-RT, mid-RT, and pre-RT registered to the corresponding mid-RT volumes. Each MRI volume is accompanied by a label mask, generated by merging independent annotations from a minimum of three experts. For both tasks, we propose adopting the nnU-Net V2 framework by the use of a 15-fold cross-validation ensemble instead of the standard number of 5 folds for increased robustness and variability. For pre-RT segmentation, we augmented the initial training data (150 pre-RT volumes and masks) with the corresponding mid-RT data. For mid-RT segmentation, we opted for a three-channel input, which, in addition to the mid-RT MRI volume, comprises the registered pre-RT MRI volume and the corresponding mask. The mean of the aggregated Dice Similarity Coefficient for GTVp and GTVn is computed on a blind test set and determines the quality of the proposed methods. These metrics determine the final ranking of methods for both tasks separately. The final blind testing (50 patients) of the methods proposed by our team, $$RUG\_UMCG$$ R U G _ U M C G , resulted in an aggregated Dice Similarity Coefficient of 0.81 (0.77 for GTVp and 0.85 for GTVn) for Task 1 and 0.70 (0.54 for GTVp and 0.86 for GTVn) for Task 2.

AbstractWith the growing energy crisis and environmental problems in recent years, the green energy technology represented by fuel cell technology has been developing rapidly. Since air contains a large amount of nitrogen that does not participate in the reaction, the circulation of nitrogen in the cathode gas supply system will increase the power consumption of the air compressor, resulting in a lower net power output of the fuel cell system. In order to improve the output performance of the fuel cell system, a new fuel cell cathode gas supply system with oxygen and air mixing is proposed in this paper, and the research results show that this topology can effectively increase the output power of the stack and reduce the power consumption of the air compressor, which can eventually increase the net power of the system to more than 10%. This study provides an effective theoretical guide for the design of fuel cell system and the optimal matching of cathode gas supply system.

Full textAbstract:
Erosion control blankets (ECBs) protect soil from being detached and transported by raindrops and subsequential overland runoff while assisting in vegetation growth. ECBs have several characteristics, for example, thickness, mass per unit area, tensile strength, elongation, water absorption, etc. However, the impact of these characteristics on the performance in mitigating erosion has yet to be well understood. To better understand the interactions of ECB properties with the detachment and transport of sediment, field tests were conducted at the Erosion Control Research and Training Center at the University of Illinois Urbana-Champaign. Various ECBs, including net-free ECBs and bionet ECBs, were tested on a 3H:1V hillslope under a 30-minute simulated rainfall event (2 in./hr). The soil used on the testing plot was silty clay loam. To investigate ECB effectiveness, total runoff volume, runoff start/end time, peak runoff rate, and sediment yield were monitored during each test. The results showed that water absorption played a big role in enhancing the performance of ECBs. The materials absorbed a large amount of water at the beginning and then acted as a wet film to cover the hillslope, reducing soil erosion by the overland flow when the soil was saturated. This wet film continued to reduce soil detachment, although it probably did not help with runoff reduction after saturation. Among the blankets tested, Profile F4 Netless was the most degradable and lightest one. North American Green DS75 had the most cost efficiency with $0.4 /sq. yd. There was no big difference in the installation method.

Full textAbstract:
The rising global temperature is detrimentally impacting Earth’s ecosystem. This research sets out to understand if cultivating seaweed can lead us to Net-Zero, in a just manner. Seaweed absorbs carbon through the process of photosynthesises; increasing the volume of cultivated seaweed in turn, increases the level of carbon dioxide absorbed. This research found that carbon sequestration is not the only benefit of seaweed; seaweed biomass can be used as a biofuel, reducing the need for fossil fuels; and seaweed can be introduced to cattle feed to reduce their methane production. The future of seaweed cultivation is dependent on further research, diversifying farmed species, global integration with equitable opportunities for all, development in technologies, investment and a change to legislation.

Full textAbstract:
To maintain measurement accuracy, stationary volume provers must be re-proved periodically. The most direct method of determining a provers volume is through a process known as water drawing where water is circulated through the prover and swept into certified measurement volumes. Since the can volumes can be directly calibrated by national metrology agencies, the traceability chain is short. However, proving with water requires that the prover be first cleaned of any hydrocarbon product that may alter the working volume of the prover and create waste products that must be handled properly. The master meter method uses the flowing product instead of water for the prover calibration and, therefore, eliminates substantial on-site waste handling issues. A master meter system consists of a portable volume prover and a turbine or positive displacement meter that is plumbed in series with the stationary prover to provide the calibration. The increased uncertainty associated with the two-step process of proving with a master meter is specifically mentioned in the API references concerning liquid meter proving; however, there has not been significant published testing to assess the differences in the methods. The objective of this project was to provide a comparison between the volume determined via the water draw method and that determined via the master eter method. A new stationary prover was used as the target device for the prover trials. Two water draw calibrations were performed and compared to the factory-provided water draw volume. The water draw results showed that with consistent measurement techniques, the results from three independent sources were within 0.02%. It is important to note that one data set had to be adjusted (based on tests) to provide this level of agreement.

Full textAbstract:
Climate change presents both a critical threat and a unique opportunity for progress in Latin America and the Caribbean. This book delves into this dual reality, showing that climate action is fundamentally development action, as it helps countries achieve crucial development goals in the short to medium term. Reaching net zero is feasible, brings tangible economic benefits, and hinges particularly on agriculture, forestry, and other land uses. Successful climate action will also require widespread public support, grounded in a shared perception that policies are fair and effective. This volume can serve as a resource for governments, the private sector, and citizens in their quest to navigate these perils while seizing the promise that climate action can offer.

Full textAbstract:
Blockchain-based systems are run by a decentralized network of participants and are designed to be censorship-resistant. We use sanctions imposed by the U.S. Department of Treasury on Tornado Cash (TC), a smart contract protocol, to study the impact and effectiveness of regulation in decentralized systems. We document an immediate and lasting impact on TC following the sanction announcement, measured by market reaction, transaction volume, and diversity of users. Still, net flows into TC contracts recover to and surpass pre-announcement levels for most pools, supporting viability of TC. Evidence on cooperation at the settlement layer is mixed: the aggregate share of non-cooperative blocks increases over time, but a shrinking number of actors process Tornado Cash transactions, indicating a fragility to the sustainability of censorship-resistance. Non-cooperation is not explained by tokenomics, and changes in perception around legal authority and clarity of regulation appears to be a key factor for whether to cooperate.
