Authors: Nascimento Silva Patrícia , Da Silva Gabriel Vieira Pereira
Published: December 2023

Objetivo: Descrever o processo de coleta de dados na Application Program Interface (API) de dados agregados do IBGE, que disponibiliza dados agregados de pesquisas e censos realizados no Brasil.
Método: Esta pesquisa caracteriza-se como descritiva e exploratória, com abordagem qualitativa, e aplicada por envolver um problema prático que é a recuperação de dados na API dados agregados do IBGE. Para tanto, foi realizada uma pesquisa documental para identificar as rotas disponíveis e os parâmetros existentes na API que permitiram implementar, de forma visual, o algoritmo de funcionamento do recurso, sendo este utilizado para guiar a construção dos endpoints para coleta.
Resultados: A API possui um endpoint principal que deve incluir parâmetros de localidade, período, metadados e variáveis de forma unificada. Assim, para apresentar as pesquisas agregadas e sua respectiva granularidade, a documentação disponibilizada possui, além de informações textuais, uma funcionalidade para construção do endpoint. Essa funcionalidade demonstrou ser importante para o “consumo” da API, pois permitiu ao usuário que não tem conhecimento do domínio selecionar uma pesquisa, seus dados agregados, as variáveis, os períodos, o nível geográfico e a localidade, por meio de componentes visuais, convertendo as necessidades do usuário ao padrão da API para realizar a coleta de forma automatizada.
Conclusão: A API de dados agregados do IBGE possui uma documentação que permitiu seu “consumo” de forma automatizada, requisito essencial para promover a interoperabilidade e o efetivo reúso dos dados governamentais abertos. O serviço demonstrou ser estável e as rotas e parâmetros estavam em conformidade com os registros disponibilizados.

Electronic cigarettes were commercially introduced in the United States and Europe in 2006, and their usage has dramatically increased in recent years. Also known as e-cigarettes, vapes, or pods, these portable devices heat liquids to produce inhalable vapor, which typically contains propylene glycol, glycerin, flavorings, and often nicotine. These devices can pose health risks as they contain lead derivatives, carcinogenic agents, and cytotoxic substances. However, there is emerging evidence that vaping devices can introduce high levels of dangerous chemicals into the body and cause severe lung injuries. The involvement of smoking in the progression of periodontal diseases and its impact on the periodontal ligament and gum cells result in detrimental effects on oral health, making them the primary targets. Therefore, the objective of this study was to conduct a literature review on the implications of electronic devices on oral health. It is crucial for dentists to stay updated on this information so that they can guide their patients in the care and prevention of avoiding or minimizing the damage caused by the use of these devices. In conclusion, electronic cigarettes are harmful to oral health and are not considered safe
Evolution of angular momentum during the collapse of magnetic rotating protostellar clouds

Published: December 2023

В работе представляются численные магнитогазодинамические (МГД) расчеты изотермической стадии коллапса маг- нитных вращающихся протозвездных облаков солнечной массы при различных начальных значениях вращательной и магнитной энергий и с различной степенью неоднородности. Моделирование осуществляется с помощью двумерного МГД-кода Enlil. Расчеты показывают, что при увеличении начальной степени неоднородности облака увеличиваются размеры элементов его иерархической структуры — сплюснутой оболочки и первичного диска — и усиливается вли- яние магнитного торможения в центре облака. Магнитное торможение отводит в межзвездную среду от 40 до 90% полного углового момента облака в зависимости от начального отношения магнитной энергии облака к модулю гравитационной энергии, ε m = 0.2 − 0.6. Эффективность переноса углового момента слабо зависит от начально- го отношения вращательной и гравитационной энергий. В конце изотермической стадии коллапса неоднородного протозвездного облака формируется «мертвая» зона со степенью ионизации x ≤ 10 −12 . Радиус «мертвой» зоны со- ставляет 90 − 220 а. е. для облаков с ε m = 0.2 − 0.6. Сравнение характерных диффузионного и динамического времен показывает, что амбиполярная диффузия приведет к ослаблению магнитного торможения внутри «мертвой» зоны в течение 1 − 10 тыс. лет после образования первого ядра.

We present the results of numerical magnetohydrodynamic (MHD) simulations of the isothermal stage of the collapse of magnetic rotating protostellar clouds of solar mass at various initial values of rotational and magnetic energies and with various degrees of nonuniformity. The simulations are carried out using the two-dimensional MHD code Enlil. The simulations show that an increase in the initial degree of inhomogeneity of the cloud leads to the growth of the sizes of the elements of its hierarchical structure — oblate envelope and primary disk. The influence of magnetic barking also increases in the center of the cloud. Magnetic barking transports from 40 to 90% of the total angular momentum of the cloud into the interstellar medium, depending on the initial ratio of the cloud’s magnetic energy to the modulus of its gravitational energy, ε m = 0.2 − 0.6. The efficiency of angular momentum transport weakly depends on the initial ratio of rotational and gravitational energies. At the end of the isothermal stage of the collapse of an inhomogeneous protostellar cloud, a “dead” zone is formed with the degree of ionization x ≤ 10 −12 . The “dead” zone radius is 90−220 au for clouds with ε m = 0.2−0.6. A comparison of the characteristic diffusion and dynamical times shows that ambipolar diffusion will lead to weakening of magnetic braking inside the “dead” zone within 1 − 10 thousand years after the first core formation.

Plantations represent a vital economic sector in Indonesia. However, farmers who rely on plantations for their livelihood often encounter challenges related to air and soil quality, which can significantly impact plant growth. Each type of plant requires specific air and soil conditions to thrive optimally, including factors such as air temperature, humidity, soil moisture, and pH levels. To address these issues, a solution has been developed in the form of a plantation monitoring system that can be accessed remotely and in real-time through cellular and desktop applications. This monitoring system utilizes various sensors, including DHT11 sensors, resistive soil moisture sensors, and soil pH sensors, all of which are meticulously calibrated with digital soil sensors. The collected data can be conveniently monitored and managed through an Internet of Things platform, such as Blynk.Based on the case study, the measurement system that is displayed on Blynk has a range of 0-100 °C for air temperature, 0-100% for air humidity, 0-1000 for soil moisture, and 0-14 for soil pH.

In today’s society, the relationship between humans and animals is constantly changing. This shift, often referred to as the ‘animal turn’, started in the 1970s and has led to a paradigm shift: animals are seen as individuals, as subjects rather than objects. Until recently, pet cemeteries have been primarily studied from within theological, cultural, and sociological frameworks. Language, however, has only been scarcely examined, if at all. Pet cemeteries are places where foreign languages are used, and the study looks at the manifestations and origins of these languages. A comparison of inscriptions from the cemeteries showed that mourning is expressed in a much more emotional way in a German cemetery (here: Saarbrücken) than in a cemetery in Finland (here: Turku), where mourning is more reserved. The number of texts in the Turku cemetery is significantly lower than the number of inscriptions in Saarbrücken. In addition to examining the verbalization of mourning, this study offers other interesting issues to be explored: language diversity on pet gravestone inscriptions, dialectal variation, pet names and regional differences among pet gravestones within both countries.

A Salmonella sp., uma bactéria geralmente habitante no trato intestinal dos animais, está presente em diversos alimentos, como os ovos, carnes (suínas e bovinas, principalmente), leite bovino e em verduras. A bactéria é responsável pela salmonelose e pela febre tifóide em seres humanos, considerada uma bactéria de caráter zoonótico. O presente estudo busca analisar a contaminação cruzada de carnes por essa bactéria dentro de açougues em todo o Brasil através de uma revisão de literatura em um período de dez anos, com exceção para análise de obras antigas que são consagradas na área. Os textos selecionados são de repositórios acadêmicos, revistas, sites relacionados e manuais do Ministério da Saúde. Durante o estudo, percebe-se que os casos acontecem principalmente em estabelecimentos com poucas inspeções e com manuseio incorreto de carnes, inclusive na produção de embutidos artesanais, como linguiças.

Comparison of six approaches to predicting droplet activation of surface active aerosol – Part 2: Strong surfactants
Authors: Vepsäläinen Sampo , Calderón Silvia M. , Prisle Nønne L.
Published: December 2023

Abstract. Surfactants have been a focus of investigation in atmospheric sciences for decades due to their ability to modify the water uptake and cloud formation potential of aerosols. Surfactants adsorb at the surface and can decrease the surface tension of aqueous solutions. In microscopic aqueous droplets with finite amounts of solute, surface adsorption may simultaneously deplete the droplet bulk of the surfactant. While this mechanism is now broadly accepted, the representation in atmospheric and cloud droplet models is still not well constrained. We compare the predictions of five bulk–surface partitioning models documented in the literature to represent aerosol surface activity in Köhler calculations of cloud droplet activation. The models are applied to common aerosol systems, consisting of strong atmospheric surfactants (sodium myristate or myristic acid) and sodium chloride in a wide range of relative mixing ratios. For the same particles, the partitioning models predict similar critical droplet properties at small surfactant mass fractions, but differences between the model predictions increase significantly with the surfactant mass fraction in the particles. Furthermore, significantly different surface tensions are predicted for growing droplets at given ambient conditions along the Köhler curves. The inter-model variation for these strong surfactant particles is different than previously observed for moderately surface active atmospheric aerosol components. Our results highlight the importance of establishing bulk–surface partitioning effects in Köhler calculations for a wide range of conditions and aerosol types relevant to the atmosphere. In particular, conclusions made for a single type of surface active aerosol and surface activity model may not be immediately generalized.

Abstract. Since 1999, Environment and Climate Change Canada (ECCC) has been coordinating a multi-laboratory comparison of measurements of long-lived greenhouse gases in whole air samples collected at the Global Atmosphere Watch (GAW) Alert Observatory located in the Canadian High Arctic (82∘28′ N, 62∘30′ W). In this paper, we evaluate the measurement agreement of atmospheric CO2, CH4, N2O, SF6, and stable isotopes of CO2 (δ13C, δ18O) between leading laboratories from seven independent international institutions. The measure of success is linked to target goals for network compatibility outlined by the World Meteorological Organization's (WMO) GAW greenhouse gas measurement community. Overall, based on ∼ 8000 discrete flask samples, we find that the co-located atmospheric CO2 and CH4 measurement records from Alert by CSIRO, MPI-BGC, SIO, UHEI-IUP, and ECCC versus NOAA (the designated reference laboratory) are generally consistent with the WMO compatibility goals of ± 0.1 ppm CO2 and ± 2 ppb CH4 over the 17-year period (1999–2016), although there are periods where differences exceed target levels and persist as systematic bias for months or years. Consistency with the WMO goals for N2O, SF6, and stable isotopes of CO2 (δ13C, δ18O) has not been demonstrated. Additional analysis of co-located comparison measurements between CSIRO and SIO versus NOAA or INSTAAR (for the isotopes of CO2) at other geographical sites suggests that the findings at Alert for CO2, CH4, N2O, and δ13C–CO2 could be extended across the CSIRO, SIO, and NOAA observing networks. The primary approach to estimate an overall measurement agreement level was carried out by pooling the differences of all individual laboratories versus the designated reference laboratory and determining the 95th percentile range of these data points. Using this approach over the entire data record, our best estimate of the measurement agreement range is −0.51 to +0.53 ppm for CO2, −0.09 ‰ to +0.07 ‰ for δ13C, −0.50 ‰ to +0.58 ‰ for δ18O, −4.86 to +6.16 ppb for CH4, −0.75 to +1.20 ppb for N2O, and −0.14 to +0.09 ppt for SF6. A secondary approach of using the average of 2 standard deviations of the means for all flask samples taken in each individual sampling episode provided similar results. These upper and lower limits represent our best estimate of the measurement agreement at the 95 % confidence level for these individual laboratories, providing more confidence for using these datasets in various scientific applications (e.g., long-term trend analysis).
On mechanisms for high-frequency pump-enhanced optical emissions at 557.7 and 630.0 nm from atomic oxygen in the high-latitude F-region ionosphere

Published: December 2023

Abstract. The EISCAT (European Incoherent Scatter Scientific Association) Heating facility was used to transmit powerful high-frequency (HF) electromagnetic waves into the F-region ionosphere to enhance optical emissions at 557.7 and 630.0 nm from atomic oxygen. The emissions were imaged by several stations of ALIS (Auroral Large Imaging System) in northern Sweden, and the EISCAT UHF incoherent scatter radar was used to obtain plasma parameter values. The ratio of the 557.7 to 630.0 nm column emission rates changed from I5577/I6300≈0.2 for the HF pump frequency f0=6.200 MHz ≈4.6fe to I5577/I6300≈0.5 when f0=5.423 MHz ≲4fe, where fe is the ionospheric electron gyro frequency. The observations are interpreted in terms of decreased electron heating efficiency and thereby weaker enhancement at 630.0 nm for f0=5.423 MHz ≲ 4 fe. The emissions at 557.7 nm are attributed to electron acceleration by upper hybrid waves of metre-scale wavelengths that can be excited with f0=5.423 MHz ≲ 4 fe.
The first map of crop sequence types in Europe over 2012–2018
Authors: Ballot Rémy , Guilpart Nicolas , Jeuffroy Marie-Hélène
Published: December 2023

Abstract. Crop diversification is considered a key element of agroecological transition, whereas current dominant cropping systems are known to rely on only a few crop species – like cereals in Europe. To assess the benefits of crop diversification at a large scale, an accurate description of current crop sequences is required as a baseline. However, such a description is lacking at the scale of Europe. Here, we developed the first map of dominant crop sequences in Europe for the period 2012–2018. We used the Land Use Cover Area frame statistical Survey (LUCAS) dataset that provides temporally incomplete (2012, 2015 and 2018) land cover information from a stable grid of points covering Europe. Eight crop sequence types were identified using hierarchical clustering implemented on LUCAS data and mapped over Europe. We show, in France, that the relative importance of these eight crop sequence types (as estimated from LUCAS data) was highly consistent with those derived from an almost spatially exhaustive temporally complete national dataset (the French Land Parcel Identification System) for the same period, thus validating the method and typology for this country. Land use (i.e. crop production area) derived from our map of dominant crop sequences was also highly consistent with land use reported by official statistics at both national and European levels, validating the approach at a European scale. This first map of dominant crop sequences in Europe should be useful for future studies dealing with agricultural issues that are sensitive to crop rotations. The map of dominant crop sequence types in Europe derived from our work is available at https://doi.org/10.5281/zenodo.7016986 (Ballot et al., 2022).
Coexistence of two dune scales in a lowland river
Authors: Zomer Judith Y. , Vermeulen Bart , Hoitink Antonius J. F.
Published: December 2023

Abstract. A secondary scale of bedforms, superimposed on larger, primary dunes, has been observed in fluvial systems worldwide. This notwithstanding, very little is known about the morphological behavior and characteristics of this secondary scale. This study aims to better characterize and understand how two dune scales coexist in fluvial systems and how both scales adapt over time and space, considering their interdependence. The study is based on analysis of a large biweekly multibeam echo sounding dataset from the river Waal, a lowland sand-bedded river. Results reveal that the secondary dune scale is ubiquitous across space and time and not limited to specific flow or transport conditions. Whereas primary dunes lengthen during low flows, secondary dune height, lee slope angle, and length correlate with discharge. Secondary dune size and migration strongly depend on the primary dune lee slope angle and height. Secondary dunes can migrate over the lee slope of low-angled primary dunes, and their height is inversely correlated to the upstream primary dune height and lee slope angle. In the Waal river, a lateral variation in bed grain size, attributed to shipping, largely affects dune morphology. Primary dunes are lower and less often present in the southern lane, where grain sizes are smaller. Here, secondary bedforms are more developed. At peak discharge, secondary bedforms even become the dominant scale, whereas primary dunes entirely disappear but are re-established during lower flows.
Critical critical posthumanism in human geography
Authors: Ernste Huib
Published: December 2023

Abstract. In this brief contribution, I reflect on some of the newest tendencies and fashions in social theoretic thinking in the field of human geography and beyond. Human geography attracts its scholars, thinkers and audiences with its engagement to contribute to a better environment and a better world. As such human geography as a discipline is a political project, with high societal relevance. In this human engagement with the world around us, the relationship between the human and the spatial environment is of central importance, and thorough scientific conceptual reflections are crucial in a discipline that is not just political but also scientific. Geographers traditionally excel in sophisticated conceptualisations of our physical and social environment but have rather neglected the conceptualisation of the other end of this relationship, the human being and becoming. In the current debate on the various versions of posthumanism, we observe that one easily resorts to rather simplistic categorisations and qualifications of what we envision as posthuman utopias or dystopias, with sometimes also dangerous ethical consequences. In this contribution, I try to argue that, if we dig a bit deeper, with the help of the philosophical anthropology of Helmuth Plessner we gain a more nuanced and sustainable as well as ethically responsible view of the role of the posthuman self in the geography of today's world.
TOPOLOGY MODELS AND RULES: A 3D SPATIAL DATABASE APPROACH
Authors: Salleh S. , Ujang U. , Azri S.
Published: December 2023

Abstract. Spatial databases are a key component of 3D applications that require the storage, management, and manipulation of 3D objects. Topological information that describes the containment, adjacency, and connectivity of objects within a 3D space is crucial for complex spatial analysis. The need to maintain optimal storage and computation within spatial databases recommends the use of lightweight approaches such as topology rules and models. However, current spatial databases use 2D topology mechanisms and limited 3D topology functions. This study conducted experiments on existing topology rules and models within ArcGIS and Oracle spatial database. Additional 3D topology rules were also implemented to determine topological relationships between 3D objects stored in Oracle. The 3D topology rules were based on a 36-Intersection Model (36IM) that describes intersections between objects from 0D to 3D. Based on the experiments, the 2D geodatabase topology rules within ArcGIS were able to determine topological relationships between the objects stored as 2D multi-surfaces datatype. The 2D topology rules and the topology model within Oracle were also unable to support topological relationships between 3D objects. The addition of 36IM topology rules could determine topological relationships and describe the dimensions of intersections. Evidently, the support for 3D topology within spatial databases depends on the availability of 3D datatypes. Most databases that support 3D datatypes have limited support for 3D topology, whereby existing topology mechanisms require the decomposition of 3D objects. The use of 3D topology rules supports the maintenance of topological information without breaking down 3D objects into lower dimension components.

Abstract. Global land cover (GLC) change reflect the distribution and evolution process of various material types on the earth's surface. It is an important basic data for global natural resources survey and ecological environment research. Although many sets of GLC information service systems have been developed at home and abroad, but the knowledge stock of GLC has not been sufficiently mined, problems such as the knowledge sharing service of spatiotemporal change of GLC have not been solved. This paper reports how to design and construct a GLC spatiotemporal change knowledge service system, which provides users with accurate and in-time knowledge services for GLC spatiotemporal change through knowledge visualization, browsing and querying, knowledge recommendation, knowledge diagnosis, knowledge sharing, process simulation, knowledge graph building and spatiotemporal deduction.
MODELLING EVACUATION STRATEGIES UNDER DYNAMIC CONDITIONS DUE TO OBSTACLE LOCATIONS BASED ON A SEMANTIC 3D BUILDING MODELS
Authors:   Shreya, Rajan K. S.
Published: December 2023

Abstract. The evacuation path from inside a building to safe point outside becomes highly unpredictable due to changes in the local geometry or presence of obstacles during a disaster like a fire. During emergencies, Evacuees need appropriate information and hence prediction of an unobstructed path, as it emerges, needs to be computed well. Understanding the exits with its allowable people flow rate; the type - door or alternative exit such as windows, balconies, etc.; and its role as a node in the graph network is important to ensure safe and timely evacuation from a building. The study here evaluates how obstacles present in the evacuation route affect the removal of the last person. These obstacles, such as furniture, decrease the flow rate at which evacuees can escape. A subspace model is proposed for geometric spaces or carpet areas containing obstacles and is used to compute the shortest obstacle-free paths. The occupancy is considered within the subspaces containing obstacles. The proposed method clearly shows that a graph-based path generation using a subspace model improves the computation time, can be dynamically adapted, and can be scalable across geometric spaces. The results clearly show the impact of the obstacles, with a 2× to 6× rise when compared to obstacle-free scenarios.
An analytical linear two-dimensional actuator disc model and comparisons with computational fluid dynamics (CFD) simulations
Authors: Madsen Helge Aagaard
Published: December 2023

Abstract. The continuous up-scaling of wind turbines enabled by more lightweight and flexible blades in combination with coning has challenged the assumptions of a plane disc in the commonly used blade element momentum (BEM)-type aerodynamic codes for the design and analysis of wind turbines. The objective with the present work is thus to take a step back relative to the integral 1-dimensional (1-D) momentum theory solution in the BEM model in order to study the actuator disc (AD) flow in more detail. We present an analytical, linear solution for a two-dimensional (2-D) AD flow with one equation for the axial velocity and one for the lateral velocity, respectively. Although it is a 2-D model, we show in the paper that there is a good correlation with axis-symmetric and three-dimensional (3-D) computational fluid dynamics (CFD) simulations on a circular disc. The 2-D model has thus the potential to form the basis for a simple and consistent rotor induction model. For a constant loading, the axial velocity distribution at the disc is uniform as in the case of the classical momentum theory for an AD. However, an important observation of the simulated flow field is that immediately downstream of the disc the axial velocity profiles change rapidly to a shape with increased induction towards the edges of the disc and less induction on the central part. This is typically what is seen at the disc in full non-linear CFD AD simulations, which is what we compare with in the paper. By a simple coordinate rotation the analytical solution is extended to a yawed disc with constant loading. Again, a comparison with CFD, now with a 3-D simulation on a circular disc in yaw, confirms a good performance of the analytical 2-D model for this more complicated flow. Finally, a further extension of the model to simulate a coned disc is obtained using a simple superposition of the solution of two yawed discs with opposite yaw angles and positioned so the two discs just touch each other. Now the validation of the model is performed with results from axis-symmetric CFD simulations of an AD with a coning of both 20 and −20∘. In particular, for the disc coned in the downwind direction there is a very good correlation between the simulated normal velocity to the disc, whereas some deviations are seen for the upwind coning. The promising correlation of the results for the 2-D model in comparison with 3-D simulations of a circular disc with CFD for complicated inflow like what occurs at yaw and coning indicates that the 2-D model could form the basis for a new, consistent rotor induction model. The model should be applied along diagonal lines on a rotor and coupled to an angular momentum model. This application is sketched in the outlook and is a subject for future research.
Entwicklung eines Fragebogens zur Erhebung von Plant Blindness
Authors: Pany Peter , Meier Florian David , Kiehn Michael , Möller Martin
Published: December 2023

Plant blindness is the phenomenon of overlooking plants, limiting our understanding of nature and hindering awareness of their role in the carbon cycle and climate change. To address this issue, a questionnaire has been developed to measure plant blindness. It consists of four domains: visual perception, recognition of plants as living beings, knowledge of plant biology, and attitudes towards plants. The questionnaire reveals that plants are often seen as less alive than animals, and knowledge about plant biology is lacking. Further development of the questionnaire aims to calculate a composite score to evaluate plant blindness and measure the effectiveness of educational interventions.

RESOURCES AND TENSIONS IN STUDENT THINKING ABOUT STATISTICAL DESIGN
Authors: FINDLEY KELLY , MOSELY BREIN , LUDKOWSKI AARON
Published: December 2023

Reform efforts in statistics education emphasize the need for students to develop statistical thinking. Critical to this goal is a solid understanding of design in the process of collecting data, evaluating evidence, and drawing conclusions. We collected survey responses from over 700 college students at the start of an introductory statistics course to determine how they evaluated the validity of different designs. Despite preferring different designs, students offered a variety of productive arguments supporting their choices. For example, some students viewed intervention as a weakness that disrupted the ability to generalize results, whereas others viewed intervention as critical for identifying causality. Our results highlight that instruction should frame design as the balancing of different priorities: namely causality, generalizability, and power.

The object of present work is to synthesize metal carbide zeolite composite catalysts and discusses their characteristics. Metal carbide with zeolite composite was prepared in the present research. Molybdenum carbide was used as a metal carbide which was prepared by solid-state method with Ammonium molybdate tetrahydrate and commercial activated carbon as raw materials. Ion exchanged method was used to add platinum to the HY zeolite. Modified Y zeolite was prepared by using ion exchanged method by mixing the HY zeolite with Cerium nitrate. After prepared Mo2C, PtHY zeolite, and CeY a formation process take place in order to form two catalysts the first one is Mo2C/PtHY-Zeolite, while the second one is Mo2C/CePtY zeolite. Tests such as X-Ray Diffraction, Brunauer-Emmett-Teller (BET) surface area analysis, Fourier transform infrared spectroscopy (FTIR), and Thermal Gravimetric Analysis (TGA) were performed on both catalysts and the results were as follows for the molybdenum carbide the surface area was 1072 m2/g, with a pore volume of 0.541 m3, the TGA indicated that 19.58 wt% of the substance was lost, finally, the average particle size is 18.65 nm.
For the Mo2C/PtHY-Zeolite catalyst, the BET surface area was 724.55 m2/g, then the Thermal Gravimetric Analysis resulted in 10% of the catalyst being lost, and lastly, the average crystal size was 33.45nm.
Moreover, for Mo2C/CePtY catalyst, the BET surface area was 734.55 m2/g, then the Thermal Gravimetric Analysis resulted in 19% of the catalyst being lost, and the average crystal size was 40.43nm.
Sample-Efficient Hyperparameter Optimization of an Aim Point Controller for Solar Tower Power Plants by Bayesian Optimization
Authors: Zanger David , Lenz Barbara , Maldonado Quinto Daniel , Pitz-Paal Robert
Published: December 2023

This work introduces a sample-efficient algorithm to optimize the control parameters of an aim point controller for solar power tower plants. Optimizing the control parameters increases the performance of the aim point controller, and thus the efficiency of the plant. However, optimizing the parameters in simulation will not yield the true optimal parameters at the real plant due to mismatches between simulation and reality. Thus, optimization must be done at the real tower to find a true optimum. As this can be time consuming and costly, the optimizer should require a minimum number of steps. Hence, a sample-efficient optimization strategy is needed. This work introduces a new algorithm based on Bayesian Optimization (BO), which leverages multiple sets of simulation data to accelerate the optimization. The algorithm is tested on a six-dimensional test function representing an arbitrary aim point controller. The proposed algorithm outperformed standard Bayesian Optimization by reaching near optimal parameter configurations of 95% accuracy within 33% less optimization steps. In a second test, the proposed algorithm is used to optimize a simulated Vant-Hull aim point controller with two hyperparameters. Here, the algorithm also needs 33% less optimization iterations than the standard BO.

The Drivers of Farmers’ Participation in Collaborative Water Management: A French Perspective
Authors: Amblard Laurence , Guiffant Nadia , Bussière Claire
Published: December 2023

Collaborative management has developed as a main approach to solving complex environmental problems such as diffuse water pollution from agriculture. This paper aims to understand the drivers of farmers’ participation in collaborative water quality management. The role of farm characteristics, farmers’ profiles and farmers’ social networks is more particularly investigated while taking into account transaction costs. The study relies on a statistical analysis of data collected in two drinking water catchments in France. The results show that larger, more profitable farms with more equipment and access to off-farm income are more likely to participate in collaborative processes for water quality management. Furthermore, farmers’ involvement in agricultural and nonagricultural networks has a strong positive influence on their participation. These results suggest that significant costs, including transaction costs, are associated with farmers’ participation in collaborative management. Targeted support for smaller, financially constrained farms and less-connected farmers could enhance the effectiveness of the collaborative approach to diffuse pollution control.
Evaluando la eficacia y seguridad de la técnica de adipoestructuración facial: a propósito de una serie de casos
Authors: García-Guevara Víctor , Velazco Gladys
Published: December 2023

La adipoestructuracion facial es una técnica encaminada a la estructuración y organización celular de los panículos adiposos faciales a partir de la estimulación mecánica vectorial, definida por Velazco G. de la siguiente manera: “La adipoestructuración facial se define como una técnica encaminada a la reorganización paniculopática de los compartimientos grasos faciales en función a su estructura, fisiología y biomecánica, sin extraerlos en ninguna circunstancia”. Se propone un estudio en un período comprendido entre Abril – Julio del 2021, controlado con tratamiento diferido de tres sesiones, diseñado para evaluar la seguridad y la eficacia de la técnica de adipoestructuración facial, 25 pacientes femeninas entre 40 y 55 años fueron evaluadas se les sometió a tres sesiones con intervalos de cada 15 días, y posteriormente se llevó a cabo un seguimiento de rutina para seguridad y eficacia cada 30 días durante 6 meses. La seguridad fue medida de la siguiente manera: los sujetos evaluaron su dolor en el lugar del tratamiento después de cada aplicación en una escala analógica visual (EVA) de 100 mm. Durante 14 días después de cada visita de tratamiento, los sujetos registraron la naturaleza, la gravedad y la duración de cualquier evento local en el lugar de la aplicación en un diario de respuestas comunes al tratamiento (RCT) de 14 días. Cualquier trastorno persistente en el punto de tiempo de 14 días se consideró automáticamente un efecto adverso. Según lo evaluado por utilizando GAIS, el grado de mejora estética en la semana 8 después de la última sesión fue significativamente importante (92,5 %). Después de la semana 20, las mejorías valoradas con el GAIS seguían siendo visibles en el 76,9 % de los sujetos. La proporción de sujetos satisfechos con el tratamiento alcanzó un máximo del 91,8 % en la semana 4 y fue del 74,3 % en la semana 24. La adipoestructuración facial representa una modalidad efectiva y segura de abordaje terapéutico para mejorar las condiciones del envejecimiento facial, representando una alternativa que condiciona la recuperación de las condiciones biomecánicas de los compartimientos adiposos faciales en beneficio de la creación de mayores fuerzas antigravitatorias en los tejidos.

Alpha (1, 2)-fucosyltransferase (FUT1), as a candidate gene in controlling the expression of E. coli F18 receptor has been identified to determine whether an animal is resistant or susceptible to infections. This study was conducted to determine the genotypes of 150 blood samples of the three swine breeds and 20 representatives were randomly selected for sequencing. Polymerase Chain Reaction - Restriction Fragment Length Polymorphism results revealed that among the 150 blood samples, seven of the Duroc x Pietrain samples carried AG genotype which was previously reported susceptible to ETEC infection. Two AA genotypes that are presumptively resistant and 50 were presumptively susceptible as these samples carried either AG or GG genotypes from the Landrace variety. Of the Large White samples, two samples carried AA genotype and 89 have either AG or GG genotype. The twenty samples sent for DNA sequencing registered 100% homologies to Sus scrofa FUT1 gene. Twelve of the sequenced samples exhibited a shift from G to A in the 117th nucleotide and one sample had a C to T shift in the 39th nucleotide. The mutation was found in all of the Duroc X Pietrain samples as well as those samples with AA genotype. Heterozygous forms of Landrace and Large White also exhibited this mutation.
