В 1957-1959 гг. по программе 3-го международного геофизического года в центральной части хребта Сунтар-Хаята (Северо-Восток России) на площадке высокогорной метеостанции проводились измерения температуры горных пород до глубины 20 м и температуры ледникового льда до глубины 45 м на леднике № 31. В 2012-2017 гг. российско-японской экспедицией здесь были выполнены новые измерения температуры горных пород и ледникового льда. Для лучшей сравнимости результатов повторные температурные наблюдения были проведены в местах, где проходили аналогичные работы в 1957-1959 гг. Сравнение данных 1958 и 2012 гг. по средней месячной температуре ледникового льда на глубине 10 м показало ее повышение на 1.0-1.6 °С. Из-за отсутствия в 2012-2017 гг. возможности прямых измерений температуры пород на глубине 20 м был использован косвенный метод оценки ее изменений. За последние 60 лет температура горных пород на глубине нулевой годовой амплитуды по приблизительной оценке могла максимально повыситься на 1.6 °С. На четырех экспериментальных участках осуществлены режимные исследования динамики сезонного протаивания пород, а на одном - динамики промерзания сезонноталого слоя.
In 1957-1959, according to the program of the 3rd International Geophysical Year, the temperature of rocks (to a depth of 20 m) and glacier ice (to a depth of 45 m) was measured in the area of a high-mountain weather station (glacier no. 31) in the central part of the Suntar-Khayata Ridge (Northeastern Russia). In 2012-2017, the Russian-Japanese expedition carried out new measurements of the temperature of rocks and glacier ice at the same places. A comparison of the data on the mean monthly temperatures of glacier ice at a depth of 10 m in 1958 and 2012 attests to their rise by 1.0-1.6 °С. As there was no possibility to perform direct measurements of rock temperature at a depth of 20 m in 2012 -2017, we used an indirect method to estimate it at the depth of zero annual amplitude. According to our estimate, in the past 60 years, it could have increased by up to 1.6 ° C. Regime studies of the dynamics of seasonal thawing were carried out at four experimental plots; of the dynamics of freezing of the seasonally thawed layer, at one plot .

Из образцов тундровых почв (п-ов Быковский, Северная Якутия) были получены накопительные культуры психрофильных и психротолерантных бактерий, восстанавливающие трехвалентное железо при температурах 6-15 °С. Установлено, что самые высокие концентрации ионов Fe(II) наблюдались в накопительных культурах, выращенных с использованием растворимой соли трехвалентного железа в виде цитрата Fe(III). Анаэробные сообщества двух накопительных культур, полученные из проб мерзлотных почв урочища Мамонтовый Хайата и культивируемые при 15 °С, использовали в качестве акцептора электронов нерастворимый оксид Fe(III), а в качестве донора электронов - ацетат и формиат. С применением методов молекулярной биологии и биоинформатики были получены экспериментальные данные о составе микробных сообществ, населяющих почвы криолитозоны. Впервые было проведено сравнение состава природного микробного сообщества, сформированного в течение длительного времени в естественных условиях при низких температурах, и микробного сообщества, культивируемого в лаборатории. Показано, что, несмотря на холодные и олиготрофные условия, прокариотные сообщества арктических экосистем Северной Якутии филогенетически разнообразны. В природных образцах доминируют представители филумов Proteobacteria и Actinobacteria (~30-50 %). Однако основную массу культивируемого микробного сообщества, полученного в лабораторных условиях, составляли Firmicutes (38 %)
Enrichment cultures of psychrophilic and psychrotolerant bacteria capable of reducing ferric iron at temperatures of 6 to 15 °C were obtained from samples of two tundra soils from the Bykovsky Peninsula (Northern Yakutia, eastern sector of Russian Arctic). The highest concentrations of Fe(II) ions were observed in enrichment cultures grown with the use of a soluble ferric salt in the form of Fe(III) citrate. Furthermore, anaerobic communities from two enrichment cultures derived from permafrost soil samples of the Mammoth Khayata tract and cultivated at 15 °C demonstrated a preference for insoluble Fe(III) oxide as an electron acceptor while utilizing acetate and formate as electron donors. Experimental data on the composition of microbial communities inhabiting permafrost soils were obtained through molecular biology and bioinformatics methods. Notably, this study presents a novel comparison between the composition of a naturally occurring microbial community that developed over an extended period under natural conditions at low temperatures, and a laboratory-cultivated microbial community. The results demonstrate that prokaryotic communities of the soils of Arctic ecosystems of Yakutia are phylogenetically diverse despite the cold and oligotrophic (nutrient-poor) conditions. While representatives of Proteobacteria and Actinobacteria phyla dominate in natural samples of tundra soil (~30-50 %), the cultivated microbial community obtained in vitro from natural samples was dominated by Firmicutes (38 %).

Published: September 2024

Abstract
Metasurfaces can replace bulk optical components in a more compact form factor in applications including communication systems, sensors, and manufacturing technology. However, their design and fabrication is challenging due to competing demands of selecting meta-atoms that simultaneously provide the required amplitude and phase modulation while being robust to fabrication errors. Here, we develop two design heuristics to assist with the down-selection of meta-atoms into sensitivity-informed libraries, based on either selecting meta-atoms with minimal sensitivity or minimizing the relative sensitivities between meta-atoms. We evaluate both methods on a polarization-dependent phase mask and compare the resulting phase and intensity errors.

Published: September 2024

AbstractThis paper presents the pull-out bonding behaviour and mechanical performance of recycled carbon fibre (rCF) reinforced concrete based on the recent investigation of fibre reinforced concrete (FRC) with rCF recovered from pyrolysis. Single fibre pull-out tests have been carried out to identify the apparent interfacial shear strength of different types of rCF and virgin carbon fibre (vCF) to identify the fibre matrix connection. Furthermore, a series of tests have been carried out to identify the workability, compressive strength and tensile strength of FRC. Besides rCF, also vCF and steel fibre were used for fabrication of FRC test specimens. rCF have shown the same adhesion behaviour and strength like vCF. Furthermore, the use of unsized or acrylate-based sized rCF creates an adhesion between fibre and matrix material. During the pull-out tests, the failure does not occur as an adhesive crack between fibre and cement matrix, but as a cohesive crack in the cement matrix. The mechanical performance of FRC with rCF was compared with mortar and FRC with vCF and steel fibres. The results of compressive test conducted for FRC with vCF and rCF indicated that the influence of vCF and rCF on the compressive strength of FRC was insignificant. On the other hand, the results of tensile test conducted for FRC with vCF and rCF indicated that the tensile strength of FRC with rCF was at least 14.9% greater than that of FRC with vCF.
Direct tensile tests on steel fiber reinforced concrete with focus on wall effect and fiber orientation

Published: September 2024

AbstractAdding steel fibers to concrete essentially improves its post-crack tensile properties. To determine this experimentally, indirect methods, such as flexural tensile tests, are generally used, which allow only indirect conclusions about the material´s tensile properties. In contrast, direct tensile tests provide the desired result immediately, but are difficult to realize. A key parameter affecting the performance of the SRFC is the orientation of the fibers, which is mainly influenced by the manufacturing process. Typically, when the concrete is cast, the steel fibers align with the edges of the formwork. This is commonly called the wall effect. We address these issues, presenting the setup and results of direct tensile tests on bone shaped specimens with three different steel fiber contents. For each content, a series of specimens with a three-sided formwork (i.e. three-sided wall effect and strong influence on the fiber orientation) and a series with cut-out bones (i.e. one-sided wall effect and less influence on fiber orientation) were fabricated and tested. After these tests, the fiber orientation was determined using an opto-analytical method to quantify the influence of the manufacturing methods on the fiber orientation. Comparing the stress-crack-opening relationships shows that the cut specimens at 0.5 mm crack openings have only about 80% of the tensile strength of three-sided formwork specimens. This effect decreases with larger crack openings and vanishes at about 3 mm crack opening. Finally, a new fiber reinforcement index is defined to correlate observed stress in direct tensile tests to fiber content and orientation in direct tensile tests.

Background: The Myrtaceae family represents one of the most diverse groups in South America. Yet, there are few studies on their reproductive characteristics. Among the species with limited information on their reproductive behavior are Myrceugenia euosma (O. Berg) D. Legrand and Siphoneugena reitzii D. Legrand.
Questions: What are the floral attractions and resources of M. euosma and S. reitzii for pollinators? Who are the pollinators of these species? What is the predominant reproductive system in both species?
Studied species: M. euosma and S. reitzii, two sympatric Myrtaceae from southern Brazil.
Study site and dates: Urubici, Painel, and Rio Rufino, Santa Catarina state, southern Brazil. November 2021 - February 2022.
Methods: Information was obtained on morphological aspects, anthesis time, stigmatic viability, floral resources, structures attractive to visitors, olfactory testing, observation and identification of floral visitors, and reproductive system testing.
Results: The flowers of M. euosma opens between 11 am and 17 pm (- 20 pm), with full opening occurring mostly at night; S. reitzii flowers open between 4 a.m. and 6 a.m., with a highest peak by 8 a.m. Flowers of both species have receptive stigmas until senescence. Pollen is the primary floral reward and the scent coming from the anthers combined with the floral display attract native bees and Apis mellifera, legitimate pollinators of both species. The lack of fruit development in the self-pollination tests support cross reproduction in both taxa.
Conclusions: Both species exhibit traits consistent with melittophily syndrome and potential self-incompatibility. These results are essential for conservation efforts.

Published: September 2024

Neurocysticercosis is commonly known as cysticercosis, which is the most common parasitic disease of the human nervous system caused by the parasitic tapeworm The development of lesions in the brain and leptomeninges and the consequent onset of symptoms associated with NCC is mainly due to the host immune-inflammatory response. The absolute diagnostic criteria include histological conformation of parasites, evidence of subretinal cysts, and demonstration of the scolex within a cyst. It is treated by a course of steroids or immunosuppressants; for intravascular cysts, endoscopic surgery is the procedure of choice as it is minimally invasive.We present a case of 8-year-old female patient who was admitted to the Neurology ward with the chief complaints of loss of consciousness, involuntary movements, headache, fever, and onset of seizures associated with vomiting. She had a seizure episode at the age of 2 years associated with fever, but no treatment was done. She was not on any past medication and was hemodynamically stable. Her lab investigations of magnetic resonance imaging show infective granuloma in the left parietal lobe with mass effect as described above, suggesting neurocysticercosiswhich should be carefully observed at an early stage. We summarized the case report of neurocysticercosis, its diagnosis, and treatment plan.

Klebsiella pneumoniae is a Gram-negative bacterium that poses a threat to the global community. Currently, no vaccine for K. pneumoniae is licensed by the Food and Drug Administration (FDA). The delay in the manufacture of the K. pneumoniae vaccine was because many vaccine candidates failed at the clinical trial stage due to adverse cross-reactions. Pili can be used as a choice as a vaccine candidate. Pili K. pneumoniae is an immunogenic substance that triggers an immune response, one of which is the cytokine IFN-Î³. Splenic splenocytes are the main source of IFN-Î³-producing cells. The aim of this study is to determine the effect of immunization pili protein 65.5 kDa K. pneumoniae on IFN-Î³ levels from spleen BALB/c mice. There were 3 groups, K1 as control given PBS, K2 given pili protein 65.5 kDa + adjuvant, and K3 given adjuvant. IFN-Î³ was then measured by the ELISA method and analyzed by the ANOVA test. The results of measuring IFN-Î³ levels using One-way ANOVA showed that the total for all groups was 243.50 ± 43.7 with p < 0.05, the Post Hoc LSD test was continued. The Post Hoc test showed significant differences between K1 control and K2 groups, and between K1 and K3 groups, but not between K2 and K3 groups. It can be concluded that immunization with 65.5 kDa of pili protein does not affect the increase in IFN-Î³ levels in the spleen of BALB/c mice.
