Published: May 2024

This study aimed to examine the effect of career anxiety on high school students' career decision-making. The study group of the research consists of a total of 449 students, 146 boys (32.5%) and 303 girls (67%), who continue their education in different high schools in Konya center and districts. Research data was obtained using the "Personal Information Form" prepared by the researchers, the "Career Anxiety Scale" developed by Çetin-Gündüz and Nalbantoğlu-Yılmaz (2016) and the "Vocational Decision Making Inventory" developed by Çakır (2004). A relational screening model based on a descriptive method was used in the research. In the analysis of the data, parametric statistical techniques such as t test, one-way analysis of variance (ANOVA), Tukey test, correlation and regression analysis techniques were used according to the normality test. According to the research findings, there is a significant relationship between both career anxiety regarding family influence and career anxiety regarding career choice and all sub-dimensions of career decision-making. In addition, there is a low level positive relationship between students' career concerns related to family influence and the sub-dimensions of internal conflicts, not knowing oneself well enough, lack of profession and field knowledge, and irrational beliefs about career choice, and a moderate positive relationship between the students' career concerns and the external conflicts sub-dimension. It was found that there was a relationship.

Introducción. La reforestación y restauración de los ecosistemas forestales son cada vez más difíciles en el contexto del cambio climático.
Objetivos. Definir zonas de transferencia de semillas para reforestación en la Reserva de la Biosfera Mariposa Monarca y el programa ‘Sembrando Vida’ en la Meseta Purépecha, para compensar el cambio climático.
Materiales y métodos. Se generaron mapas para visualizar dónde se predicen las condiciones climáticas idóneas para la reforestación con plántulas de semilla colectada en zonas delimitadas bajo un clima de referencia (1961- 1990) que se proyecta ocurrirá (escenario RCP 4.5, 2050) en sitios distintos. Se utilizó una zonificación climática (basada en la temperatura del mes más frío e índice de aridez) y capas de hábitat climático propicio para Pinus pseudostrobus y Abies religiosa del periodo de referencia (1961-1990) y proyectado (década 2060).
Resultados y discusión. Las áreas por reforestar serán más cálidas en el futuro, por lo  que  se  requiere semilla de sitios, en promedio, 3 °C más cálidos. Se estimó una reducción de aproximadamente 50 % de la superficie del hábitat climático propicio de P. pseudostrobus y A. religiosa. Tal reducción ocurre en el límite inferior altitudinal denominado ‘límite xérico’, por lo que será necesario el reemplazo de estas por especies adaptadas a sitios más cálidos.
Conclusiones. Se recomienda el traslado de las fuentes de semillas de lugares más cálidos (+3 °C) y secos a sitios de plantación actualmente más húmedos y fríos. Este enfoque proporciona una herramienta útil para decidir la fuente de semilla bajo un manejo forestal adaptativo ante el cambio climático.

They face challenges regarding how to utilize cattle manure waste as environmentally friendly organic fertilizer. The objective of this community service is: 1) To provide knowledge to the farming community in Labuan Lelea Village on how to utilize cattle manure waste as organic fertilizer, as a substitute for inorganic fertilizers, which are known for their chemical content, scarcity, and fluctuating prices annually; 2) To promote organic fertilizers as an environmentally friendly alternative to inorganic fertilizers in agricultural lands; 3) To enhance the knowledge of farming communities regarding the effective utilization of cattle manure waste as organic fertilizer for both food crops and horticultural plants. The method employed in this activity is a participatory approach, wherein a team including Community and Student Service Learning Program (KKN) participants and local community members actively collaborate in fostering good cooperation between extension workers and farmers. The primary target audience of this training is farming communities engaged in plantation, food crops, and horticultural cultivation. The outcomes of this community service activity include increased awareness of how to utilize cattle manure waste (Bos Taurus). This process requires minimal investment as cattle waste, sawdust, and rice husks are all freely available materials, thus serving as a substitute for inorganic fertilizers which contain chemical substances and are environmentally unfriendly.
Seed from olive cake prevents hyperglycemia, hyperlipidemia, and oxidative stress in dexamethasone-induced diabetes rats
Authors: Garba Mansourou Samba , Bouderbala Sherazede
Published: May 2024

Background: Diabetes mellitus, a leading cause of global morbidity and mortality, can be managed with both pharmacological and non-pharmacological interventions. However, However, current medications often come with significant costs and side effects, including hypoglycemia, liver failure, and congestive heart failure. This highlights the need for exploring alternative strategies, such as dietary antioxidants and nutraceuticals, for diabetes prevention and complication management. Aims: This study investigated the potential of olive seed powder (OSP) supplementation to prevent diabetes, hyperlipidemia, and oxidative stress induced by dexamethasone in rat, utilizing both in vivo and in silico approaches. Material and Methods: Male rats were distributed into three groups: control (Ctl), preventive (D-OSP, receiving OSP supplementation), and dexamethasone-treated (Dx). Over 14 days, all groups received intraperitoneal dexamethasone injections, while the preventive group received a diet supplemented with 10% OSP. Results: Compared to the Dx group, supplementation significantly mitigated hyperglycemia, improved glucose tolerance, and reduced the triglyceride-glucose index, glycated hemoglobin levels, and increased hepatic glycogen content. OSP also ameliorated the lipid profile, decreasing triglycerides, total cholesterol, LDL-C, atherogenic index, and coronary risk index levels, while increasing HDL-C levels. Serum and hepatic enzyme biomarker activities were elevated in the Dx compared to Ctl and OSP supplementation attenuated these changes. Furthermore, the Dx group displayed increased lipid peroxidation products and protein oxidation, alongside decreased activity of antioxidant enzymes in the liver and pancreas. PSO supplementation alleviated these markers of oxidative stress. Histopathological analysis revealed liver and pancreas damage in the Dx group, which was reduced by OSP. Additionally, the in-silico investigations indicated the potential biding of vanillic acid to the active sites of protein kinase 1, insulin receptor substrate 1, phosphatidylinositol 3-kinase, and glycogen synthase kinase-3 beta complex. Conclusion: This study demonstrates that OSP supplementation effectively prevented dexamethasone-induced hyperglycemia, dyslipidemia, and oxidative stress in rats. These beneficial effects are likely attributed to the bioactive compounds present in OSP suggesting its potential as a promising functional food for diabetes prevention and complication management.

Background: Ensuring adequate nutrition for young children is crucial for their long-term health and development. Aim: This pilot interventional study aimed to assess feeding practices and the nutrient content of meals consumed by children aged 12 – 23 months during supervised cooking demonstrations (CDs). Methods: Thirty-seven mother-child dyads (including one set of twins) were recruited from 10 sites in Southern Benin. Mothers purchased ingredients from local markets and researchers documented cooking methods, recipes, and the weight of all consumed foods. Nutrient densities of prepared meal were estimated using the FAO/INFOODS database. A questionnaire was used to evaluate child feeding practices against World Health Organization (WHO) recommendations. Results: The average nutrient density per 100 kcal of the prepared meals was 2.17 ± 0.51 g for protein, 2.85 ± 0.92 mg for vitamin C, 0.79 ± 0.24 mg for iron, and 0.51 ± 0.09 mg for zinc. While protein and vitamin C content met recommendations, iron and zinc levels fell short. Notably, 53% of mothers adhered to the best practices for child feeding outlined by the WHO. However, there was potential for further meal diversification, especially for children who were not breastfed, or consuming fewer than four meals daily. Conclusions: This study suggests that while the CD-prepared meals provided adequate energy, they lacked essential micronutrients. These findings highlight the need for educational interventions targeted towards parents of young children to promote optimal feeding practices.

Global aviation contrail climate effects from 2019 to 2021

Published: May 2024

Abstract. The current best-estimate of the global annual mean radiative forcing (RF) attributable to contrail cirrus is thought to be 3 times larger than the RF from aviation's cumulative CO2 emissions. Here, we simulate the global contrail RF for 2019–2021 using reanalysis weather data and improved engine emission estimates along actual flight trajectories derived from Automatic Dependent Surveillance–Broadcast telemetry. Our 2019 global annual mean contrail net RF (62.1 mW m−2) is 44 % lower than current best estimates for 2018 (111 [33, 189] mW m−2, 95 % confidence interval). Regionally, the contrail net RF is largest over Europe (876 mW m−2) and the USA (414 mW m−2), while the RF values over East Asia (64 mW m−2) and China (62 mW m−2) are close to the global average, because fewer flights in these regions form persistent contrails resulting from lower cruise altitudes and limited ice supersaturated regions in the subtropics due to the Hadley Circulation. Globally, COVID-19 reduced the flight distance flown and contrail net RF in 2020 (−43 % and −56 %, respectively, relative to 2019) and 2021 (−31 % and −49 %, respectively) with significant regional variations. Around 14 % of all flights in 2019 formed a contrail with a net warming effect, yet only 2 % of all flights caused 80 % of the annual contrail energy forcing. The spatiotemporal patterns of the most strongly warming and cooling contrail segments can be attributed to flight scheduling, engine particle number emissions, tropopause height, and background radiation fields. Our contrail RF estimates are most sensitive to corrections applied to the global humidity fields, followed by assumptions on the engine particle number emissions, and are least sensitive to radiative heating effects on the contrail plume and contrail–contrail overlapping. Using this sensitivity analysis, we estimate that the 2019 global contrail net RF could range between 34.8 and 74.8 mW m−2.
The impact of gaseous degradation on the gas–particle partitioning of methylated polycyclic aromatic hydrocarbons

Published: May 2024

Abstract. The partitioning of semi-volatile organic compounds (SVOCs) between gas and particle phases plays a crucial role in their long-range transport and health risk assessment. However, the accurate prediction of the gas–particle (G–P) partitioning quotient (KP′) remains a challenge, especially for the light-molecular-weight (LMW) SVOCs due to their upward deviation from equilibrium state. In this study, the phenomenon with the influence of gaseous degradation on G–P partitioning was observed. Based on the diurnal study of concentrations and KP′ values for methylated polycyclic aromatic hydrocarbons (Me-PAHs), it was found that the KP′ values of methylated naphthalenes (Me-Naps; one type of LMW SVOC) during the daytime were higher than during the nighttime, and the regression lines of log KP′ versus log KOA (octanol–air partitioning coefficient) for daytime and nighttime were non-overlapping, which were different from other Me-PAHs. Compared with other diurnal influencing factors, the higher gaseous degradation of Me-Naps in the daytime than in the nighttime should partially explain their special diurnal variation in KP′, which provided a new explanation for the non-equilibrium behavior of KP′ for LMW SVOCs. Moreover, the influence of gaseous degradation on the deviation of KP′ from equilibrium state was deeply studied based on the steady-state G–P partitioning model considering particulate proportion in emission (ϕ0). The increasing times of KP′ influenced by the gaseous degradation deviated from equilibrium state can be calculated by 1 + 13.2ϕ0 × kdeg (kdeg, gaseous degradation rate). The increase in KP′ along with the increase in kdeg proved that higher gaseous degradation in the daytime could increase the KP′ value. Furthermore, an amplification in KP′ ranging from 1.11 to 5.58 times (90 % confidence interval: 1.01 to 14.4) under different ϕ0 values (0 to 1) in the temperature range of −50 to 50 °C was estimated by the Monte Carlo analysis. In summary, it can be concluded that the influence of gaseous degradation should also be considered in the G–P partitioning models of SVOCs, especially for the LMW SVOCs, which provided new insights into the related fields.
Observing atmospheric rivers using GNSS radio occultation data
Authors: Rahimi Bahareh , Foelsche Ulrich
Published: May 2024

Abstract. Atmospheric Rivers (AR) are comparatively narrow regions in the atmosphere that are responsible for most of the horizontal transport of water vapor in the extra tropics, which are responsible for many extreme precipitation events and floodings at mid-latitudes, including Europe and the US. The critical role of ARs in global moisture transport and precipitation dynamics necessitates accurate water vapor measurements for both understanding and forecasting these phenomena. While the integrated water vapor content (IWV) of ARs can be well measured with microwave and infrared sounders, the vertical structure is less well known. In this study, we analysed if specific humidity profiles and IWV values from Global Navigation Satellite System Radio Occultation (GNSS-RO) measurements provide additional information for the study of ARs, in particular regarding their vertical structure. The retrieval of water vapor from GNSS-RO data requires background information, which is usually incorporated by the one-dimensional variational method (1D-Var) that combine observations and background in an optimal manner. We compared data from the COSMIC Data Analysis and Archive Centre (CDAAC), operated by the University Corporation for Atmospheric Research (UCAR) in Boulder, Colorado with data from the Wegener Center for Climate and Global Change (WEGC) at the University of Graz, Austria. We found that retrievals from both centres agree very well in the altitude range, where the 1D-Var weights the observations strongly, even if the employed background profiles are very different. This demonstrates that GNSS-RO data provide indeed additional vertically-resolved information, which was not already contained in the background or in operational analyses. IWV values from CDAAC and WEGC agree generally very well, however, both tend to underestimate the values obtained by Special Sensor Microwave Imager/Sounder (SSMI/S) data, since GNSS-RO profiles not always reach the lowermost part of the atmosphere, leading to a systematic bias in the IWV data, which decreases with better penetration characteristics of the GNSS-RO data. The results suggest that is promising to combine the GNSS-RO data – with very high vertical resolution with SSMI/S data – with high horizontal resolution to get a more compete view of the 3D structure of ARs.
Variations in the Biological Pump through the Miocene: Evidence from organic carbon burial in Pacific Ocean sediments
Authors: Lyle Mitchell , Olivarez Lyle Annette
Published: May 2024

Abstract. The biological pump, defined as the marine biological production and sedimentation of particulate organic carbon (Corg), is a fundamental process to fix atmospheric carbon dioxide in the oceans, transfer carbon away from the atmosphere to the deep ocean, and maintain the CO2 level of the atmosphere. The level of carbon sequestration by the biological pump has varied throughout the last 50 million years, from particularly weak in the warm Eocene to much stronger in the Holocene. However, persistently warm climates in the more recent past, e.g., the Miocene Climate Optimum (MCO; 17 million years ago [Ma] to 13.8 Ma) also have affected the biological sequestration of carbon. A series of scientific ocean drill sites from the equatorial Pacific contain very low sedimentary Corg % in the period prior to 14 Ma but higher and much more variable Corg % afterward. Although lower absolute productivity may have contributed to the lower Corg burial at the MCO, higher relative Corg degradation also occurred. Ratios of Corg to other productivity indicators indicate higher relative loss of Corg. Temperature records imply that the higher Corg degradation occurred in the upper water column, and global cooling strengthened the biological pump but led to more variability in burial. Similar records of low Corg at the MCO can be found in the North Pacific, which suggest this was a global—rather than regional—change. A weakened biological pump during warm climate intervals helps to sustain periods of global warmth.
On the role of trans-lithospheric faults in the long-term seismotectonic segmentation of active margins: a case study in the Andes
Authors: Yanez Gonzalo , Piquer Jose , Rivera Orlando
Published: May 2024

Abstract. Plate coupling play a fundamental role in the way in which seismic energy is released during the seismic cycle. This process includes quasi-instantaneous release during megathrust earthquakes and long-term creep. Both mechanisms can coexist in a given subducting margin, defining a seismotectonic segmentation in which seismically active segments are separated by zones in which ruptures stop, classified for simplicity as asperities and barrier, respectively. The spatiotemporal stability of this segmentation has been a matter of debate in the seismological community for decades. At this regard, we explore in this paper the potential role of the interaction between geological heterogeneities in the overriding plate and fluids released from the subducting slab towards the subduction channel. As a case study, we take the convergence between the Nazca and South American plates between 18°–40° S, given its relatively simple convergence style and the availability of a high-quality instrumental and historical record. We postulate that trans-lithospheric faults striking at a high angle with respect to the trench behave as large fluid sinks that create the appropriate conditions for the development of barriers and promote the growth of highly coupled asperity domains in their periphery. We tested this hypothesis against key short- and long-term observations in the study area, obtaining consistent results. If the spatial distribution of asperities is controlled by the geology of the overriding plate, seismic risk assessment could be established with better confidence.

Published: May 2024

Abstract. Ice-nucleating particles (INPs) have an important function in the freezing of clouds, but are rare in East Antarctica with concentrations between 6 × 10-6 L-1 and 5 × 10-3 L-1 observed at the Belgian Princess Elisabeth Station. These low concentrations offer a possible explanation for the occurrence of supercooled liquid water in clouds observed using the station's Micro Rain Radar and Ceilometer. We used COSMO-CLM² with an added aerosol-cycle module to test the cloud phase’s sensitivity in response to varying prescribed INP concentrations. We tested two cases, one in austral summer, one in austral winter, and analysed the differences resulting from INP concentration changes for an area around the station and over the Southern Ocean within the selected domain. Our results show a strong influence of the INP concentration on the liquid water path in both regions, with higher concentrations reducing the amount of liquid water. Over the ocean, this effect is stronger during winter: During summer, a significant portion of water remains in liquid state regardless of INP concentration. Over the continent, this effect is stronger during summer: Temperatures in winter frequently fall below -37 °C, allowing homogeneous freezing. The largest increase of the liquid water fraction of total cloud hydrometeor mass is simulated over the ocean in winter, from 9.8 % in the highest tested INP concentration to 50.3 % in the lowest. The radiative effects caused by the INP concentration changes are small with less than 3 W m-2 difference in the averages between different concentrations.
Spectral Induced Polarization survey for the estimation of hydrogeological parameters in an active rock glacier
Authors: Moser Clemens , Morra di Cella Umberto , Hauck Christian , Flores Orozco Adrián
Published: May 2024

Abstract. Degrading permafrost in rock glaciers has been reported from several sites in the European Alps. Changes in ground temperature and ice content are expected to affect the hydrogeological properties of the rock glacier and in turn modify the runoff regime and groundwater recharge in high-mountain environments. In this study, we investigate the use of an emerging geophysical method to understand the hydrogeological properties of the active Gran Sometta rock glacier, which consists of a two lobe-tongue (a white and a black) differing in their geologies. We present the application of the spectral induced polarization (SIP) imaging, a method that provides continuous spatial information about the electrical conductivity and polarization of the subsurface, which are linked to hydrogeological properties. To quantify the water content and the hydraulic conductivity from SIP imaging results, we used the petrophysical dynamic stern layer model. The SIP results show a continuously frozen layer at 4−6 m depth along both lobes which hinders the infiltration of water leading to a quick flow through the active layer. To evaluate our results, we conducted tracer experiments monitored with a time-lapse electrical conductivity imaging which confirms the hydraulic barrier associated with the frozen layer and allows to quantify the pore water velocity (~10-2 m/s). Below the frozen layer, both lobes have distinct water content and hydraulic conductivity. We observed a higher water content in the black lobe, which moves faster than the white lobe supporting the hypothesis that the water content at the shear horizon dominates rock glacier velocity. Our study demonstrates that the SIP method is able to provide valuable information for the hydrogeological characterization of rock glaciers.

Abstract. The Surface Water and Ocean Topography (SWOT) mission delivers unprecedented swath altimetry products. Despite SWOT’s 2D coverage and precision, its Level-2 products suffer from the same limitations as their counterparts from nadir altimetry missions. Level-2 products are designed in a standalone ground-segment to meet the mission’s primary science objectives. In contrast, some research domains and applications require consistent multi-mission observations such as the Level-3 products provided by the Data Unification and Altimeter Combination System (DUACS) for almost 3 decades, and with 20 different satellites. In this paper, we describe how we extended the Level-3 algorithms to handle SWOT’s unique swath-altimeter data. We also illustrate and discuss the benefits, relevance, and limitations of Level-3 swath-altimeter products for various research domains.
European forest cover during the Holocene reconstructed from pollen records
Authors: Sweeney Luke Fionn , Harrison Sandy P. , Vander Linden Marc
Published: May 2024

Abstract. Changes in tree cover influence many aspects of the Earth System. Recent regional changes in tree cover, as documented by remote-sensed observations, are insufficient to capture the response to large climate changes or to differentiate the impacts of human activities from natural drivers. Pollen records provide an opportunity to examine the causes of changes in tree cover in response to large climate changes in the past and during periods when human influence was less important than today. Here we reconstruct changes in tree cover in Europe through the Holocene using fossil pollen records, using the modelled relationship between observed modern tree cover and modern pollen samples. At a pan-European scale, tree cover is low at the beginning of the Holocene but increases rapidly during the early Holocene and is maximal at ca. 6,500 cal. BP, after which tree cover declines to present-day levels. The rapidity of the post-glacial increase in tree cover and the timing and length of maximum tree cover varies regionally, reflecting differences in climate trajectories during the early and mid-Holocene. The nature of the subsequent reduction in tree cover also varies, which may be due to differences in climate but may also reflect different degrees of human influence. The reconstructed patterns of change in tree cover are similar to those shown by previous reconstructions, but our approach is more robust and less data-demanding than previously applied methods and therefore provides a useful approach to reconstructing tree cover in regions where data limitations preclude the use of alternative methods.
Rate-induced tipping cascades arising from interactions between the Greenland Ice Sheet and the Atlantic Meridional Overturning Circulation

Published: May 2024

Abstract. The Greenland Ice Sheet (GIS) and Atlantic Meridional Overturning Circulation (AMOC) are considered tipping elements in the climate system, where global warming exceeding critical threshold levels in forcing can lead to large-scale and nonlinear reductions in ice volume and overturning strength, respectively. The positive–negative feedback loop governing their interaction with a destabilizing effect on the AMOC due to ice loss and subsequent freshwater flux into the North Atlantic as well as a stabilizing effect of a net cooling around Greenland with an AMOC weakening may determine the long-term stability of both tipping elements. Here we explore the potential dynamic regimes arising from this positive–negative tipping feedback loop in a physically motivated conceptual model. Under idealized forcing scenarios we identify conditions under which different kinds of tipping cascades can occur: herein, we distinguish between overshoot/bifurcation tipping cascades, leading to tipping of both GIS and AMOC, and rate-induced tipping cascades, where the AMOC, despite not having crossed its own intrinsic tipping point, tips nonetheless due to the fast rate of ice loss from Greenland. The occurrence of these different cascades is affected by the ice sheet disintegration time and thus eventually by the imposed forcing and its timescales. Our results suggest that it is necessary not only to avoid surpassing the respective critical levels of the environmental drivers for the Greenland Ice Sheet and Atlantic Meridional Overturning Circulation, but also to respect safe rates of environmental change to mitigate potential domino effects.

Abstract. Engaging ecological resource users in intervention to protect the resource is challenging for governments due to self-interest of users and uncertainty about intervention consequences. Focusing on a case of forest insect infestations, we addressed questions of resource protection and environmentally responsible behavior promotion with a conceptual model. We coupled a forest infestation model with a social model in which a governing agent applies a mechanism for recognition and promotion of environmentally responsible behavior among several user agents. We ran the coupled model in various scenarios with a Reinforcement Learning algorithm for the governing agent as well as best-case, worst-case, and random baselines. Results showed that a proper recognition policy facilitates emergence of environmentally responsible behavior. However, ecosystem health may deteriorate due to temporal differences between the social and ecological systems. Our work shows it is possible to gain insight about complexities of social-ecological systems with conceptual models through scenario analysis.
Velocity correction for the Actuator Line Method
Authors: Selvatici Davide , Stevens Richard J. A. M.
Published: May 2024

Abstract. We introduce a velocity correction designed to mitigate the overestimation of aerodynamic loads observed with the traditional Actuator Line Method (ALM) at the blades tip. The correction is based on Blade Element Momentum (BEM) theory to determine the ratio of tip-corrected to non-tip-corrected axial and tangential velocity components. These velocity ratios are used to correct the velocities at the blade locations, ensuring an accurate representation of aerodynamic effects near the blade tips. The correction only requires the Tip Speed Ratio (TSR), which can be estimated from local flow conditions and turbine specifications. This makes the method highly adaptable to various flow scenarios. The effectiveness of the proposed correction has been validated through Large Eddy Simulations (LES) at multiple inflow velocities through comparison against both BEM with tip correction and a vortex-based smearing correction for ALM.

Este livro foi pensado para ser um primeiro texto didático e introdutório às bases ecológicas e evolutivas do comportamento humano, voltado para o ensino ao nível de graduação. Porém, este livro também pode ser útil para aqueles entrando na pós-graduação, especialmente vindos de áreas sem muita tradição de ensino e pesquisa ecológica e evolutiva. Embora cada capítulo possa ser lido em qualquer ordem, organizamos o livro de modo que a sequência sugerida, que vai do geral ao mais específico, permita ao aprofundamento gradual dos diferentes conceitos e disciplinas dedicadas aos estudos ecológicos e evolutivos do comportamento e da mente humana.

Observa-se que muitas empresas e instituições de pesquisas vêm atuando no desenvolvimento de tecnologias mais sustentáveis de combate e controle do mosquito Aedes aegypti, por meio do desenvolvimento de armadilhas contendo substâncias atrativas orgânicas para potencializar essa atratividade. E uma dessas possibilidades é a glicerina industrial residual. Assim, o objetivo deste estudo é analisar o cenário tecnológico do uso de glicerina em estratégias contra o mosquito Aedes aegypti, através de prospecção patentária, utilizando a ferramenta de recuperação gratuita de patentes de cobertura internacional, The Lens. Os códigos CPC das patentes estudadas indicaram principalmente o desenvolvimento de substâncias biocidas, repelentes e atrativas a base de glicerina. E que a glicerina vem sendo bastante utilizada por empresas e instituições em estratégias contra o mosquito Aedes aegypti, podendo se tornar um potencial produto orgânico atrativo utilizado em armadilhas de monitoramento.

Количественные оценки структур и разрушения обеспечивают более полную и объективную ранжировку качества металлопродукции и выявление структурных причин его неоднородности, что принципиально важно для полноценной реализации принципа управления качеством по структуре. В практике цифровых измерений структур не всегда должное внимание уделяется их метрологическому обеспечению. В этой связи в работе оценены некоторые метрологические факторы цифрового анализа изображений структур, которые влияют на получение объективных результатов.

Quantitative assessments of structures and destruction provide a more complete and objective ranking of the quality of metal products and the identification of structural causes of its heterogeneity, which is fundamentally important for the full implementation of the principle of quality management by structure. In the practice of digital measurements of structures, due attention is not always paid to their metrological support. In this regard, the paper evaluates some metrological factors of digital image analysis of structures that affect the obtaining of objective results.
