Published: March 2022

Процесс прогнозирования экологических катастроф как техногенного, так и природного характера в настоящее время базируется на достижениях в области математического моделирования. Получение прогноза за короткое время является весьма затруднительным без применения параллельных вычислений и суперкомпьютерных технологий. Большой объем обрабатываемой информации и сложность вычислений приводят к необходимости использования вычислительных кластеров, в состав которых добавляются видеоадаптеры для увеличения производительности вычислительной системы и скорости обработки информации. Статья посвящена разработке программного модуля на языке CUDA C, предназначенного для моделирования гидродинамических процессов мелководных водоёмов, включая решение возникающих при дискретизации систем сеточных уравнений высокой размерности. Для повышения эффективности расчетов часть вычислительной нагрузки передавалась на графические ускорители, для чего был разработан алгоритм параллельных расчетов и его программная реализация в виде модуля. В результате вычислительных экспериментов определена оптимальная двумерная конфигурация потоков в вычислительном блоке, исполняемом на одном потоковом мультипроцессоре. Разработанные алгоритм и программный модуль позволяют более эффективно задействовать вычислительные ресурсы графических ускорителей, используемых для решения вычислительно трудоемких задач гидрофизики.
Forecasting environmental disasters, both artificial and natural, is currently based on advances in simulation. Fast forecasting is very difficult without the use of parallel computing and supercomputer technologies. The large volume of information to be processed and the complexity of calculations require to use of computing clusters with graphics cards to increase the computing performance and the data processing rate. This paper deals with the development of a software module in CUDA C to simulate the hydrodynamic processes in shallow water bodies, including the solution of systems of high-dimensional grid equations during discretization. To improve computing performance, graphics accelerators take a part of the load. To enable this, we developed an algorithm for parallel calculations and implemented it as a software module. As a result of computational experiments, the optimal 2D configuration of streams in a computational unit run on a single streaming multiprocessor was determined. The proposed algorithm and software module enables more efficient use of GPU computational resources when solving computationally intensive hydro physics problems.
Grazing enhances carbon cycling but reduces methane emission during peak growing season in the Siberian Pleistocene Park tundra site

Published: March 2022

Abstract. Large-herbivore grazing has been shown to substantially alter tundra soil and vegetation properties as well as carbon fluxes, yet observational evidence to quantify the impact of herbivore introduction into Arctic permafrost ecosystems remains sparse. In this study we investigated growing-season CO2 and CH4 fluxes with flux chambers on a former wet tussock tundra inside Pleistocene Park, a landscape experiment in northeast Siberia with a 22-year history of grazing. Reference data for an undisturbed system were collected on a nearby ungrazed tussock tundra. Linked to a reduction in soil moisture, topsoil temperatures at the grazed site reacted 1 order of magnitude faster to changes in air temperatures compared to the ungrazed site and were significantly higher, and the difference strongly decreased with depth. Overall, both GPP (gross primary productivity, i.e., CO2 uptake by photosynthesis) and Reco (ecosystem respiration, i.e., CO2 release from the ecosystem) were significantly higher at the grazed site with notable variations across plots at each site. The increases in CO2 component fluxes largely compensated for each other, leaving NEE (net ecosystem exchange) similar across grazed and ungrazed sites for the observation period. Soil moisture and CH4 fluxes at the grazed site decreased over the observation period, while in contrast the constantly waterlogged soils at the ungrazed site kept CH4 fluxes at significantly higher levels. Our results indicate that grazing of large herbivores may promote topsoil warming and drying, in this way effectively accelerating CO2 turnover while decreasing methane emissions in the summer months of peak ecosystem activity. Since we lack quantitative information on the pre-treatment status of the grazed ecosystem, however, these findings need to be considered qualitative trends for the peak growing season, and absolute differences between treatments are subject to elevated uncertainty. Moreover, our experiment did not include autumn and winter fluxes, and thus no inferences can be made for the annual NEE and CH4 budgets in tundra ecosystems.

Abstract. The roughness of the land surface (z0) is a key property, exerting significant influence on the amount of near-surface turbulent activity and consequently the turbulent exchange of energy, water, momentum, and chemical species between the land and the atmosphere. Variations in z0 are substantial across different types of land cover, ranging from typically less than 1 mm over fresh snow or sand deserts up to more than 1 m over urban areas or forests. In this study, we revise the parameterizations and parameter choices related to z0 in the Community Land Model 5.1 (CLM), the land component of the Community Earth System Model (CESM). We propose a number modifications for z0 in CLM, guided by observational data. Most importantly, we find that the observations support an increase in z0 for all types of forests and a decrease in the momentum z0 for bare soil, snow, glaciers, and crops. We then assess the effect of those modifications in land-only and land–atmosphere coupled simulations. With the revised parameterizations, diurnal variations of the land surface temperature (LST) are dampened in forested regions and are amplified over warm deserts. These changes mitigate model biases compared to MODerate resolution Imaging Spectroradiometer (MODIS) remote sensing observations. The changes in LST are generally stronger during the day than at night. For example, the LST increases by 5.1 K at 13:30 local solar time but only by 0.6 K at 01:30 during boreal summer across the entire Sahara. The induced changes in the diurnal variability of near-surface air temperatures are generally of the opposite sign and of smaller magnitude. Near-surface winds accelerate in areas where the momentum z0 was lowered, such as the Sahara, the Middle East, and Antarctica, and decelerate in regions with forests.
Overall, this study finds that the current representation of z0 in CLM is not in agreement with observational constraints for several types of land cover. The proposed model modifications are shown to considerably alter the simulated climate in terms of temperatures and wind speed at the land surface.

A HUMANIZAÇÃO DO PARTO - SUA INFLUÊNCIA NA PRÁTICA DE EPISIOTOMIA SEM INDICAÇÃO CLÍNICA
Authors: Moreira de Sousa Jorge Luiz , Vilanova Araújo Raquel 
Published: March 2022

Mesmo com a existência das recomendações, observa-se que no Brasil tem sido frequente o emprego inapropriado da episiotomia, e, portanto das implicações negativas para a mulher como o desconforto físico, riscos de infecção pós-parto, aumento de perdas sanguínea, disfunção sexual e outras. O estudo objetiva saber se a humanização do parto influencia na prática de episiotomia sem indicação. Trata-se de um estudo de revisão integrativa da literatura realizado em seis etapas interligadas: elaboração da pergunta norteadora, busca na literatura, coleta de dados, análise crítica dos estudos incluídos, discussão dos resultados e apresentação da revisão integrativa. Utilizou-se a estratégia PICo, em que P refere-se à população (Gestantes em trabalho de parto); I refere-se ao interesse do estudo (Uso da Episiotomia); C refere-se ao contexto em que o estudo se pauta (Humanização do parto vaginal) e O aplica-se aos resultados (Parto normal sem Episiotomia). Observa-se que a episiotomia é uma prática inapropriada e prejudicial à saúde da mulher quando não recomendada. É um dos procedimentos cirúrgicos mais utilizados na obstetrícia atual, chegando ao alarmante percentual entre 12,2% a 75%, contrariando a Organização Mundial da Saúde – OMS que preconiza apenas 10% excepcionalmente. Concluímos que as contribuições da pesquisa visam aprofundar a discussão de que a prática da episiotomia em partos vaginais está absolutamente em desacordo com a OMS, afirmando que devemos adotar medidas de cuidado comprovadas cientificamente. A prática da episiotomia de forma indiscriminada sem indicação clínica configura-se negligencia e desrespeito a mulher, colocando o binômio mãe-filho em situação de risco.

Published: March 2022

In several areas throughout the world, the eggs of the fictitious host insect, Corcyra cephalonica, are used to produce multiple natural enemies, such as Trichogramma species, which are widely utilized for biological control of lepidopterous pests on diverse crops in more than 30 nations. The purpose of this study was to determine the efficacy of RH-5849, a non-steroidal ecdysone mimic, on the gonadotrophic parameters of the rice moth, Corcyra cephalonica. The separated II instar larva received the compound topically on the abdomen dorsum by means of Hamilton micro syringe in acetone. Five replicates (50 insect/replicate) were used per each dosage. Similar replicates were used for the control insects without any treatment. The mean number of eggs laid by a female moth was worked out on the basis of the total number of eggs laid by ten females. In a dose-dependent way, the sterility percentage was enhanced while the hatching percentage was decreased. The sterility indices were shown to be dose-dependent, according to current data. It should not be forgotten that the hatching percentages reversed this effectuation tendency (egg viability).
