Published: June 2021

To increase the data capacity of a light-emitting diode (LED) based visible light communication (VLC) transmission, a polarization-division-multiplexing (PMD) green (G)- and blue (B)- light-based transmitter (Tx) module is demonstrated here. It was demonstrated that we can achieve 1200 and 1120 Mbps VLC capacities based on dual-polarized G- and a B-LED based light wave after 3 and 4 m free-space link lengths, respectively, at exceedingly low illuminance. Based on the presented VLC system, paired G-LEDs or B-LEDs with dual-polarization can also be applied on the VLC-Tx side for doubling and delivering VLC data. According to the obtained results, the largest polarization offset angle of 50° between two polarizers (POLs) can be allowed experimentally to provide optimal VLC traffic. Moreover, the relationships of polarization offset, the illuminance of LED and maximum achieved VLC capacity are also performed and analyzed.

Published: June 2021

The use of biofertilizers, including biocontrol agents such as Pseudomonas and Bacillus in agriculture can increase soil characteristics and plant acquisition of nutrients and enhancement the efficiency of manure and mineral fertilizer. Despite the problems that liquid and solid formulations have in maintaining the viability of microbial agents, encapsulation can improve their application with extended shelf-life, and controlled release from formulations. Research into novel formulation methods especially encapsulation techniques has increased in recent years due to the mounting demand for microbial biological control. The application of polymeric materials in agriculture has developed recently as a replacement for traditional materials and considered an improvement in technological processes in the growing of crops. This study aims to overview of types of biopolymers and methods used for encapsulation of living biological control agents, especially microbial organisms.
Microstructure and Mechanical Performance of Resistance Spot Welded Martensitic Advanced High Strength Steel
Authors: Li Yunzhao , Tang Huaping , Lai Ruilin
Published: June 2021

Resistance spot welded 1.2 mm (t)-thick 1400 MPa martensitic steel (MS1400) samples are fabricated and their microstructure, mechanical properties are investigated thoroughly. The mechanical performance and failure modes exhibit a strong dependence on weld-nugget size. The pull-out failure mode for MS1400 steel resistance spot welds does not follow the conventional weld-nugget size recommendation criteria of 4t0.5. Significant softening was observed due to dual phase microstructure of ferrite and martensite in the inter-critical heat affected zone (HAZ) and tempered martensite (TM) structure in sub-critical HAZ. However, the upper-critical HAZ exhibits obvious higher hardness than the nugget zone (NZ). In addition, the mechanical properties show that the cross-tension strength (CTS) is about one quarter of the tension-shear strength (TSS) of MS1400 weld joints, whilst the absorbed energy of cross-tension and tension-shear are almost identical.

Authors: Zinoveev Dmitry , Pasechnik Liliya , Fedotov Mikhail , Dyubanov Valery , Grudinsky Pavel , Alpatov Andrey
Published: June 2021

Bauxite residue, known as red mud, is a by-product of alumina production using the Bayer process. Currently, its total global storage amounts to over 4.6 billion tons, including about 600 million tons in Russia. The total global storage of red mud occupies large areas, leading to environmental damage and increasing environmental risks. Moreover, it contains a significant amount of sodium, which is easily soluble in subsoil water; therefore, a sustainable approach for comprehensive recycling of red mud is necessary. The bauxite residue contains valuable elements, such as aluminum, titanium, and scandium, which can be recovered using liquid media. In recent years, many methods of recovery of these elements from this waste have been proposed. This paper provides a critical review of hydrometallurgical, solvometallurgical, and complex methods for the recovery of valuable components from red mud, namely, aluminum, titanium, sodium, and rare and rare-earth elements. These methods include leaching using alkaline or acid solutions, ionic liquids, and biological organisms, in addition to red mud leaching solutions by extraction and sorption methods. Advantages and disadvantages of these processes in terms of their environmental impact are discussed.

Authors: Otto William R. , Lamson Daryl M. , Gonzalez Gabriel , Weinberg Geoffrey A. , Pecora Nicole D. , Fisher Brian T. , St. George Kirsten , Kajon Adriana E.
Published: June 2021

Background: Human adenovirus (HAdV)-D56 was first described in 2011 by genomics analysis of a strain isolated in France in 2008 from a fatal case of neonatal infection. Since then, it has been reported in cases of keratoconjunctivitis and male urethritis. Three epidemiologically unrelated fatal cases of neonatal sepsis associated with infection by HAdV-D strains with a similar genetic makeup were documented in the United States between 2014 and 2020. Methods: Whole genome sequences were obtained for the isolated strains, and genomics analyses were conducted to compare them to phylogenetically related HAdV-D genomic sequences available in GenBank. Results: The three new US strains were indistinguishable by in silico restriction enzyme analysis. Their genome sequences were 99.9% identical to one another and to the prototype strain isolated in 2008 from a similar context of disease. The phylogenetic reconstruction revealed a highly supported clustering of all HAdV-D56 strains isolated in various countries since 1982. Our comparison to serologically intermediate strains 15/H9 described in the literature indicated that HAdV-D56-like viruses have circulated worldwide since the late 1950s. Conclusion: As with other HAdV-D genotypes with the ability to infect ocular and genital mucosae, the risk of severe prenatal or perinatal HAdV-D56 infection must be considered.

Published: June 2021

The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the world is still expanding. Thus, there is an urgent need to better understand this novel virus and find a way to control its spread. Like other coronaviruses, the nucleocapsid (N) protein is one of the most crucial structural components of SARS-CoV-2. This protein shares 90% homology with the severe acute respiratory syndrome coronavirus N protein, implying functional significance. Based on the evolutionary conservation of the N protein in coronavirus, we reviewed the currently available knowledge regarding the SARS-CoV-2 N protein in terms of structure, biological functions, and clinical application as a drug target or vaccine candidate.

Published: June 2021

Alternatives to the antibiotic fumagillin for the control of Nosema ceranae, a gut parasite of the honey bee, are needed. The prebiotics eugenol, chitosan, and naringenin and the probiotic Protexin® (Enterococcus faecium) provided in sugar syrup or protein patty either in spring or fall were evaluated for their effects on N. ceranae infection, colony population, honey yield and winter survivorship using field colonies. In the first year, spring treatments with eugenol, naringenin, and Protexin® significantly reduced N. ceranae infection and increased honey production, while Protexin® also increased adult bee populations and chitosan was ineffective. Fall treatments increased survivorship and decreased N. ceranae infection the following spring. In the second year, selected compounds were further tested with a larger number of colonies per treatment and only protein patty used in the spring and sugar syrup in the fall. Protexin® and naringenin significantly decreased N. ceranae infections and increased the population of adult bees after spring treatment, but did not affect honey yields. There were no differences between treatments for colony winter mortality, but surviving colonies that had been treated with Protexin® and naringenin were significantly more populated and had lower N. ceranae spore counts than control, non-treated colonies. Protexin® and naringenin were the most promising candidates for controlling N. ceranae and promoting honey bee populations, warranting further investigation. Future research should investigate the optimal colony dose and treatment frequency to maximize colony health.
Influence of Substrate Material on Flow in Freezing Water Droplets—An Experimental Study
Authors: Fagerström Erik , Ljung Anna-Lena , Karlsson Linn , Lycksam Henrik
Published: June 2021

Freezing water droplets are a natural phenomenon that occurs regularly in the Arctic climate. It affects areas such as aircrafts, wind turbine blades and roads, where it can be a safety issue. To further scrutinize the freezing process, the main objective of this paper is to experimentally examine the influence of substrate material on the internal flow of a water droplet. The secondary goal is to reduce uncertainties in the freezing process by decreasing the randomness of the droplet size and form by introducing a groove in the substrate material. Copper, aluminium and steel was chosen due to their differences in thermal conductivities. Measurements were performed with Particle Image Velociometry (PIV) to be able to analyse the velocity field inside the droplet during the freezing process. During the investigation for the secondary goal, it could be seen that by introducing a groove in the substrate material, the contact radius could be controlled with a standard deviation of 0.85%. For the main objective, the velocity profile was investigated during different stages of the freezing process. Five points along the symmetry line of the droplet were compared and copper, which also has the highest thermal conductivity, showed the highest internal velocity. The difference between aluminium and steel was in their turn more difficult to distinguish, since the maximum velocity switched between the two materials along the symmetry line.
Sterlet reproduction in the Volga region as a complex structural problem of aquaculture development
Authors: Kalayda Marina Lvovna , Borisova Svetlana Dmitrievna , Khamitova Madina Farhadovna , Kalayda Andrey Andreevich
Published: June 2021

Changes in the Volga River and its fish population are considered in the historical aspect. The importance of studies of sterlet in the composition of ichthyofauna in the period before the regulation of the river and after the creation of a cascade of reservoirs is shown. The ideas of ichthyologists of the early and late 20th century on the reproduction of sterlet are presented. Data on the decrease in catches of sterlet and its inclusion in the Red Data Books is presented. It is noted that for a long period the main task of sterlet reproduction was considered to be — release into natural reservoirs to replenish the local fish stock. The required amount of young sterlet for the annual release into the Kuibyshev reservoir for the task of removing sterlet from the Red Data Book was determined — 8.6 million. For the task of forming its livestock in accordance with the plan for reorganizing the “Big Volga” and increasing its catches to the planned values in catches in the reservoir, an annual release of 57 million pieces is required. The need is shown at the present stage of development of biotechnology for growing and reproducing sterlet in the structure of tasks to bring the commercial reproduction of sterlet and its hybrids to the first place in terms of volumes. This will provide people with healthy food and enhance the country’s food security. Dividing the reproduction of sterlet into separate tasks will also make it possible to involve in this process numerous farmers who are ready to raise sturgeon fish, but who do not have sufficient training to select fish in accordance with their genotypic characteristics. Expansion of commercial production will potentially relieve some of the load on natural aquatic ecosystems and optimize the release of juveniles.

Published: June 2021

The fishing structure and amount of vertebrate and invertebrate biological resources are estimated for small limnoecosystems in the forest-steppe zone of the Western Siberia south-west part. The predominance of fish farming based on the maximum use of the natural abiotic and biotic (feeding) resources of the ecosystems, mainly with annual growth of fishes, is noted. Negative abiotic, anthropogenic and socio-economic factors hindering the efficient use of aquatic biological resources are considered. On the Kurgan region territory dominate the small lakes without flow out which has small area (1.0–1.5 km2 ) and depth (up to 3–4 m) with sloping shores, which overgrowing of Phragmites australis. Most lakes are mesotrophic with average biomass of phytoplankton, zooplankton and zoobenthos, as well as the concentration of biogenic matter, or eutrophic. On the Kurgan region territory are in total 7102 lakes of different genesis and size, which area is more than 0.001 km² according to the decoding results of satellite images performed at the Institute of Lake Science of the Russian Academy of Sciences 2010–2013 years (“Lakes of Russia” Information System). For 2019, in the Kurgan region, 3,857.5 tons of aquatic biological resources were obtained as a result of fishing. 99.3% of the total amount of products is accounted for by lake nature use. Fishing increased by 1.3 times compared to 2018. In 2019, 2087 tons of fish of both indigenous and introduced fish species were caught, which amounted to only 45% of the recommended quotes at the region’s lakes. The main part is accounted for by such aboriginal species as crucian (Carassius gibelio, 895.5 tons per year), and peled (Coregonus peled, 1999.4 tons per year). In addition to fish resources, the region lakes are sources of non-fish aquatic biological resources — invertebrate limnobionts. The main species are Gammarus lacustris (Amphipoda) and Artemia salina parthenogenetica (Branchiopoda).

In the paper, rearing results and comparative assessment of interspesific hybrids and pure species of the Siberian sturgeon Acipenser baerii (Brandt, 1869)and the Russian sturgeon Acipenser gueldenstaedti (Вrandt, 1833) have been provided at various stages of ontogenesis by combinated cultivation under RAS conditions and in an industrial uniflow tank farm. Investigations were carried out at the “Konakovski” department of the Branch on Freshwater Fisheries FSBSI “VNIRO” (VNIIPRKh). To obtain the experimental material breeders were used of the Siberian sturgeon from the sixth domestication generation and of the Russian sturgeon from the third one. Fish fry, switched to mixed feeding ongrowing and further rearing, were cultivated under production conditions in normal technological mode and separately from each female using different granulated mixed feeds (BioMar firm) of different recipes. Up to 41 day-age fish were reared in RAS, further in race-ways and tanks of the shop with uniflow water-supply. The middle water temperature was 16ºC during the all period of experimental works (557 days). Best results of the mass accumulation showed interspecific LS×RS hybrids, at the second position seemed to be RS×LS hybrids. Pure species of the Siberian and Russian sturgeons showed practically similar middle weights to the end of the experimental stage. As a result of the histological analysis, it has been ascertained that gonads of pure species of one-year-old Siberian and Russian sturgeons and their hybrids had comparatively the same picture of sex cells development, but some advantage possessed the Siberian sturgeon and LS×RS hybrid. Thus, malesʼ cysts and femalesʼ nests of one-year-old fish show multiple mitotic divisions of sex cells (spermatogonia and oogonia) what corresponds with the first stage of gonades maturity in males and the first one and the beginning of the second ones in females.

Authors: Suvorova Tatyana Alexandrovna , German Alexander Vladimirovich
Published: June 2021

The composition of leukocytes reflects the species and ecological characteristics of fish, while the ratio of individual cell types reflects the functional state of the organism and the nature of the influence of biotic and abiotic stress factors. The work is devoted to the issues of hematopoiesis of the bream Abramis brama — one of the main commercial species of the Volga. The fish were caught in September 2019 at the Saratov Reservoir during a complex hydrobiological expedition aboard the Akademik Topchiev research vessel of the IBIW RAS. In total, 18 sexually mature bream were examined, caught at 3 standard trawling stations: 1 — Shirokiy Buerak, 2 — Khvalynsk, 3 — Kashpir-Rudnik. In fish, peripheral blood was sampled from the tail vein and tissues of the spleen and head kidney. Blood smears and organ imprint smears were performed for the study. The preparations were examined under a light microscope and the leukocyte formula was determined. To determine the index of the abundance of leukocytes in a peripheral blood smear, 100 visual fields were examined at different sites. The leukocyte abundance index allows the intensity of leukopoiesis to be recorded and indirectly assesses the leukocyte level in a blood volume unit. The results of the study showed that lymphocytes predominate in the leukocyte formula, a significant part are blast forms and a small percentage of granulocytes and monocytes/macrophages. The established differences depended on the structural and functional features of the organs: in the kidneys, as the main organ of hematopoiesisin teleost fish, a higher content of blast forms of cells, granulocytes and macrophages was noted, and in the spleen, which serves as a “depot” of blood, lymphocytes and macrophages. Blood, as an integral system, bears all types of cells circulating in the immune system at the moment. The intensity of leukopoiesis was higher in fish from the upper part of the reservoir.
Community end-of-life care during the COVID-19 pandemic: findings of a UK primary care survey
Authors: Mitchell Sarah , Oliver Phillip , Gardiner Clare , Chapman Helen , Khan Dena , Boyd Kirsty , Dale Jeremy , Barclay Stephen , R Mayland Catriona
Published: June 2021

Background

Thousands of people in the UK have required end-of-life care in the community during the COVID-19 pandemic. Primary healthcare teams (general practice and community nursing services) have provided the majority of this care, alongside specialist colleagues. There is a need to learn from this experience in order to inform future service delivery and planning.

Aim

To understand the views of GPs and community nurses providing end-of-life care during the first wave of the COVID-19 pandemic.

Design & setting

A web-based, UK-wide questionnaire survey circulated via professional general practice and community nursing networks, during September and October 2020.

Method

Responses were analysed using descriptive statistics and an inductive thematic analysis.

Results

Valid responses were received from 559 individuals (387 community nurses, 156 GPs, and 16 unspecified roles), from all regions of the UK. The majority reported increased involvement in providing community end-of-life care. Contrasting and potentially conflicting roles emerged between GPs and community nurses. There was increased use of remote consultations, particularly by GPs. Community nurses took greater responsibility in most aspects of end-of-life care practice, particularly face-to-face care, but reported feeling isolated. For some GPs and community nurses, there has been considerable emotional distress.

Conclusion

Primary healthcare services are playing a critical role in meeting increased need for end-of-life care in the community during the COVID-19 pandemic. They have adapted rapidly, but the significant emotional impact, especially for community nurses, needs addressing alongside rebuilding trusting and supportive team dynamics.

Published: June 2021

Phytophthora blight (Phytophthora capsici) is one of the major soilborne diseases threatening many vegetable crops including squash. The disease results in severe epidemics and yield losses due to a rapid spread of the pathogen associated with wet weather and soil waterlogging. Implementing drone-based spatial mapping with software elevation tools can assist growers in evaluating land levelling for uniform distribution of water to mitigate potential disease incidence. The technology has great advantages: rapid, precise, and labor-cost effective. Our result can implicate Extension professionals with application of spatial mapping to assist growers in managing their land and crops for disease control efficiently.
Rapid-response observations on barrier islands along Cape Fear, North Carolina, during Hurricane Isaias
Authors: Mieras Ryan , O'Connor Christopher , Long Joseph
Published: June 2021

Hurricane Isaias struck the Cape Fear Region of North Carolina around 23:00 EDT on 3 August 2020, making landfall at Ocean Isle Beach as a Category 1 storm with peak wind speeds of 80 mph. An array of nearshore Sofar Spotter wave buoys captured the wave field at two beaches off the coasts of Bald Head Island (south-facing and east-facing beaches) and Masonboro Island. Local variations in significant wave height and peak wave direction were observed along the Lower Cape Fear Region, due to large shoal features impacting the regional wave climate. A cross-shore transect of five pressure sensors was installed at the north end of Masonboro Island 2.5 days prior to landfall to measure storm surge, wave runup, and variation of gravity/ infragravity wave energy across the barrier island. The three fast-sampling wave gauges along the backshore became buried before Hurricane Isaias peak storm surge, and the two gauges on and behind the dune were never inundated. A low-cost (< $250) Storm Surge Observation Camera (SSOC) prototype captured storm surge and coastal erosion at Kure Beach, in conjunction with pre- and post-storm RTK GPS beach profile surveys. Kure Beach experienced more than 1.0 m of vertical erosion of the berm, while Masonboro Island experienced around 0.1 m of accretion across the backshore, despite nearly identical wave and wind forcing conditions at the two beaches separated by ~20 km. Pre-storm berm height and width (higher and wider at Kure Beach), as well as foreshore slope (steeper, 1:9, at Kure Beach), are likely factors influencing significant erosion at Kure Beach, while slight accretion was observed at Masonboro Island.

Tengkuruk Permai street is currently used for city transportation terminals, on street parking, access and exit to 16 Ilir market parking lot (off street parking), entrance to Ampera Bridge, passenger access to LRT stations and Skate Park. The various functions of this street caused the reduction in street service levels at certain hours and become a congestion point in Palembang city. This study aims to obtain the results of the analysis of Tengkuruk Permai’s street performance in the scenario conditions of terminal relocation and on street parking. The data were collected directly by measuring and enumeration then micro-simulated with the Vissim software. Vissim microsimulation modeling is carried out in existing conditions and scenarios by combining the 3 (three) floors parking building construction plans, city transport routes, Tengkuruk Permai street which has been cleared of on street parking and terminals, street networks around the research location and intersection arrangements concurrently. The street performance analysis uses the calculation of the V/C ratio, where the calculation of the street capacity uses the Vissim microsimulation output such as speed, density and volume obtained in the link of segment evaluation menu. Capacity determination is using the calculation of relation of flow (q), velocity (v) and density (k). The scenario of relocating the city transport terminal and street parking to the 3 (three) floors parking building plan at 16 Ilir market parking lot can increase the capacity of Tengkuruk Permai Street from 1087,88 pcu/hour/direction to 2295.15 pcu/hour/direction and improve the service level from level E to level A.
On the Issue of Assessing the Ecological State of Various Watercourses in the Conditions of Anthropogenic Pressure.

Published: June 2021

An assessment is given of the ecological state of nine rivers with different levels of anthropogenic load related to the Volga, the Don and the Ural basins. The water quality was assessed on the basis of several indices: the widely used specific combinatorial water pollution index (SCWPI), and statistical criteria based on the data of long-term environmental monitoring: the plasticity indicator as a measure of ecosystem sustainability and the desirability function. Hydro/chemical studies included indicators of oxygen regime, salt composition, organic matter, biogenic and toxic elements. The calculated SCWPI fluctuated in the range of 3,0–5,4, which corresponds to the quality category “very polluted” - “dirty”. The water of the lowest quality is in the small rivers Berezina and Elshanka, part of which is located in the industrial zone of the city of Saratov. The greatest contribution to the assessment of the degree of water pollution is made not only by the concentration of technogenic metals, but also by indicators of the content of organic matter, the amount of which depends on the level of bioproduction processes. The principal component analysis made it possible to structure the indices calculated for each river and to “explain” some of the information contained in the initial variables. Two main components were selected, based on the analysis results. The first factor integrates a negative relationship between the value of the UCIPI and the length of the river. Large rivers are more resistant to pollution due to their high water content. The second factor incorporated environmental criteria - the desirability function and the plasticity indicator, i.e. statistical indicators based on the data of long-term hydro/chemical monitoring and taking into account the real ecological state ̶ "health" of natural water systems and their sustainable functioning. Cluster analysis of the obtained statistical indices made it possible to divide the studied rivers by the quality of the aquatic environment into 4 groups.
