The features of the distribution of technogenic halogenesis processes on the soil of various cascade-geochemical positions of the landscape are determined. It was revealed that technogenic salinization is the most detrimental for floodplain soils, since these soils are a kind of main “collection point” for all pollutants. The features and chemistry of technogenic halogenesis processes (content, qualitative composition, patterns of migration and distribution of easily soluble salts, including those toxic to plants) in soils of various pollution zones - the epicenter, the impact zone, the boundary of the oil slick - have been established. It has been revealed that technogenic salinization of floodplain soils, the final link in cascade-geochemical systems, is a significant geoecological factor contributing to the formation of new technogenic soil-geochemical successions in oil-contaminated territories - chemozems with signs of solonchak phenomena that are not characteristic of humid climate conditions. A method for the reclamation of technogenically saline soils by phytomeliorative sowing of native halophyte plants is proposed.

Currently, a new generation of immunomodulators, cytokines, are widely used in medicine and veterinary medicine. Cytokines are active in very low concentrations, they regulate the proliferation and differentiation of cells of the immune system. Taking into account the high biological activity for cells of animal, plant and microbial origin in vivo and in vitro, we conducted the present studies, the purpose of which was to study the possibility of using cytokines as activators of the metabolism of animal cell cultures in vitro for the reproduction of viruses on them. In the experiments, cell cultures MDBK and BHK-21/13-02 obtained from the collection of cell cultures of the Federal State Budget Scientific Institution FSBSI «FCTRBS-ARRVI» were used. Nutrient media were used for growing cell cultures: Needle MEM, solution of Versen, trypsin, Hanks, bovine blood serum (BRS), fetal blood serum (FBMS). As activators of cell metabolism, commercial cytokines were used: IL-3, IL-6, colon-stimulating factor G-CSF produced by Cytokin LLC (St. Petersburg). Stimulating and inhibitory doses of cytokines were experimentally determined and added to media with cell cultures at the rate of 30 to 500 pg/cm3. It was found that among the tested classes of cytokines, interleukin-6 (IL-6) turned out to be the most active, which, when introduced into the growth medium at a concentration of 30-60 ng/cm3, had a metabolism-stimulating effect, providing a proliferation index of MDBK cells by 1.33 times and cell lines VNK-21/13-02 - 1.17 times, respectively.

Published: June 2022

Xenotransplantation is an approach which will be able to support the increasing demand of organ donation since the organ does not need to come from humans. Up till now, xenotransplantation is still barely performed since its risk and chance of success are still not proven to be safe. One of the biggest obstacles is rejection which may lead to xenograft failure and can occur in certain types and from certain causes. However, the risk of rejection can be minimized by the process of genetic engineering and applying anti-rejection drugs in which scientists and researchers are developing so that the procedure becomes safer in the future. Although the patient who was considered as the first successful xenotransplantation in human case had died a few months after the surgery and the cause of death still remains unsolved, the field of xenotransplantation still keeps developing by researchers, medical universities, and biotechnology companies since they all agree that xenotransplantation will produce lots of advantages and will be a big step of the medical treatment field. Despite the fact that xenotransplantation is a procedure that is risky and raises public concerns and ethical issues, the procedure is still believed to give more benefits towards the patient and medical development since serious problems like organ shortage and high number of deaths on the waiting list will be solved.

Discriminação de genótipos de cana-de-açúcar resistentes e suscetíveis à Diatraea saccharalis baseada em caracteres anatômicos
Authors:   , Silva Maria Eduarda Jardim
Published: June 2022

O uso de variedades resistentes é um dos métodos mais sustentáveis para o controle da broca da cana-de-açúcar (Diatraea saccharalis). Dessa forma, o objetivo deste trabalho foi descrever a anatomia foliar de genótipos de cana-de-açúcar, previamente caracterizados como resistentes e suscetíveis à Diatraea saccharalis. Para isso, foram utilizados 23 genótipos de cana-de-açúcar, sendo 13 resistentes e dez suscetíveis à broca. O experimento foi conduzido em casa de vegetação, na Estação Experimental Diogo Alves de Mello, Departamento de Agronomia, Universidade Federal de Viçosa. Foi utilizado o delineamento de blocos casualizados, com quatro repetições. Seis meses após o plantio foram coletados, de cada genótipo, a região do limbo da folha +1, primeira folha completamente desenvolvida, e a região da bainha da folha 0, folha imediatamente superior a +1, para a montagem de lâminas permanentes. O material foi observado e fotografado utilizando o microscópio Olympus AX70. Em conjunto, foi realizada a quantificação de silício presente nas folhas de cana-de-açúcar (%Si). Foram avaliadas características estruturais e anatômicas na região da bainha e do limbo foliar. Os dados foram coletados por meio do software Image Pro Plus ® e submetidos a análise de variância. Quando significativo pelo teste F, foi realizada a comparação entre as médias dos genótipos por meio do teste de Tukey em nível de 5% de probabilidade. Houve diferença significativa para a maior parte dos caracteres da região do limbo e da bainha. A %Si não permitiu a separação dos genótipos contrastantes. A espessura de epiderme na face adaxial (EAD-L) e abaxial (EAB-L) do limbo e da bainha (EAD) foram significativos (P<0,05) e apresentaram médias maiores nos genótipos resistentes. Conclui-se que a diferença da anatomia foliar entre os genótipos contrastantes dá suporte a hipótese de uma barreira física, atribuída à estrutura das folhas de cana-de-açúcar, e consista em uma das estratégias de resistência à Diatraea saccharalis. Palavras-chave: Anatomia vegetal. Melhoramento genético. Resistência de plantas. Diatraea saccharalis.

Published: June 2022

Os pequenos e médios produtores de carvão vegetal possuem significativa participação no abastecimento deste insumo no estado de Minas Gerais, que é o maior produtor e consumidor do Brasil. Estes produtores geralmente têm dificuldades em gerenciar seus ativos, levando ao menor acompanhamento dos resultados financeiros e dos riscos. O objetivo deste trabalho foi desenvolver modelos de planejamento financeiro e de gestão de risco para produtores de carvão vegetal, considerando as particularidades e os diversos cenários deste mercado. O trabalho foi estruturado em quatro capítulos. No primeiro foi discutido e proposto recomendações relacionadas às ferramentas financeiras para produtores de carvão vegetal. No segundo foram desenvolvidos modelos de planejamento financeiro para quatro sistemas produtivos de carvão vegetal, sendo eles: fornos-fornalha, rabo-quente, circular de superfície e de encosta. Os dados técnicos e econômicos foram obtidos junto a onze produtores de Minas Gerais, contemplados pelo Projeto Siderurgia Sustentável. Foram avaliados os desempenhos econômicos destes projetos por meio de indicadores e múltiplos gerados pelos modelos. Uma vez identificado o melhor desempenho financeiro do sistema fornos-fornalha, no terceiro e no quarto capítulos foram desenvolvidas análises de risco para este projeto por meio dos métodos Capital Asset Pricing Model Ajustado Híbrido (AH-CAPM), simulação de Monte Carlo e avaliação de cenários operacionais e financeiros. Foi possível determinar o custo de capital para projetos de bioenergia em mercados emergentes, que foi de 8,93% a.a., a chance de sucesso deste empreendimento, que foi de 73%, suas principais variáveis de risco, e cenários com potenciais oportunidades de geração de valor. Os modelos financeiros desenvolvidos foram capazes de gerar maior visibilidade sobre os aspectos da administração financeira para os produtores de carvão vegetal, principalmente para a disseminação do fornos-fornalha, que foi o sistema produtivo com maior viabilidade econômica e menor risco, podendo gerar rentabilidade e sustentabilidade financeira a longo prazo, sendo a sua maior inserção recomendada para os pequenos e médios produtores.

Mobility Models as a Key-Performance Factor for Wireless Networks
Authors: Abdulqader Ayad
Published: June 2022

Nodes in wireless networks can be static or dynamic. Static nodes are stationary and their positions are fixed and their distribution may follow a particular topology. On the other hand, dynamic nodes are considered mobile and their positions changed over time due to following a specific pattern of movement, which also lead to the concept of the topology being irrelated. Simulating such networks needs a lot of attention and many requirements should be held. For instance, nodes in dynamic wireless networks are distributed according to a distribution that reflects the nature of the environment (e.g., Gaussian, Power-Law, Uniform distribution, etc.). Moreover, describing the movement patterns of nodes in dynamic wireless networks need to follow a particular mobility model that describes the movements of nodes in terms of speed and direction (e.g., Individual mobility model, Levy Flight Model, Cauchy Model). In addition to the aforementioned requirements, it is needed to incorporate a routing protocol that governs data spread within the simulation environment. This work designed a variety of experiments that combine the mentioned requirements and measure the performance of dynamic wireless networks under colorful settings and configurations. The metrics used in this approach are the amount of data exchanged, coverage area, and power and memory consumption.  Mobility models, node deployment strategy (distributions), and routing protocols are the three factors that will be involved in the experiments. The experiments deal with four mobility models Random Way Point Mobility Model (RWPM), Street Random Way Point Mobility Model (SRWPM), Manhattan Mobility Model (MM), and Levy Flight Mobility Model (LFM). Three distribution models will be used in the experiments Power-Law Distribution, Chi-Squared Distribution, and Normal Distribution. The third factor that will be involved in the routing protocol, is Probabilistic Flooding Routing Protocol. Different experiments are benchmarked using these metrics. The results of this work will reveal facts about dynamic network simulations and provide some recommendations to network developers and architects.

Published: June 2022

The article deals with the results of the work of Belarus Agricultural Library in the field of acquisition of traditional sources for its collection. Printed publications have formed the basis for the development of the library collection throughout its existence with publications on agriculture, forestry, food, and related industries. At present, more and more publications are being transferred into electronic format, which undoubtedly enables users to receive the necessary information promptly, at a convenient time for them and from anywhere in the country. At the same time, access to the majority of electronic resources for libraries is provided for a certain period and on a paid basis. Therefore, there is still a need for printed publications that are kept in the library collections permanently and do not lose their relevance for a significant period. Besides, they are not only a source of unique information, but also a cultural heritage. Unfortunately, over the past years, the number of printed editions acquired the library collection has been gradually decreasing for a variety of economic, organizational and even political reasons. In this regard, the library is carrying out a purposeful and active work to develop its collection with specialized printed publications.

Shade trees in the Southwest can provide large potential energy savings for cooling and enhanced comfort for outdoor living. However, water costs for shade trees may offset space cooling savings in water-scarce regions. Computer simulation was used to calculate potential residential heating and cooling savings from several shading scenarios in Tucson, Arizona. Energy savings were compared with water costs to derive net savings for six tree species commonly used in Southwest landscapes. Dense shade on west walls reduced annual energy costs by 10-12% ($55-121), depending on the type of building construction. A surprising finding was that tree form appears to have a greater effect on energy savings than crown density and, hence, merits more attention during the tree selection process. Annual water costs were equivalent to about 20% of annual energy savings for low-water-use species and ranged from 53-261% for the high-water-use species. Water requirements are an important factor to consider when selecting shade trees for Southwest landscapes.
The Biotechnology of Urban Trees
Authors: McCown Brent
Published: June 2022

Trees are some of the most difficult plants to manipulate in breeding and improvement programs. Plant biotechnology offers a unique set of tools that allows the plant breeder heretofore unprecedented ability to precisely change and clone such woody perennials. Although the future of biotechnology of trees is revolutionary, there are some major problems that must be solved before the full potential of this technology can be applied to urban tree improvement. Nevertheless, major advances in genetic transformation, cloning, and regeneration of trees have been recorded in the last few years; continued progress will depend on the effort applied to tree biotechnology and to determining the physiological/genetic bases of urban tree growth and ecology.
Military Community Forestry Planning Offutt Air Force Base: A Case Study

Offutt Air Force Base is headquarters for the Strategic Air Command and center for many activities of national importance. This community differs from most communities because the short residency of its inhabitants means increased management of vegetation by the base staff. Most vegetation activities had low priority and were not guided by a comprehensive plan. In 1987, a contract was initiated between the Air Force and the Nebraska Forest Service to develop a Community Forestry Plan for Offutt. Existing trees were evaluated and new plantings designed. Maintenance activities were recommended. The plan provides for future community forestry action and is a model for other military communities. The plan also relates to non-military communities.

Published: June 2022

A Cylindrosporlum fungus was consistently associated with and isolated from circular leaf spots on Quercus rubra. It was examined in pure culture and on leaves by light and electron microscopy and identified as C. quercus Sorok. Growth of the fungus in culture was best at 27°C; germination of conidia was best at 24-27°C. Typical symptoms were produced on only 1 of 56 inoculated oak seedlings. This report is the first of C. quercus in Illinois and the first of a Cylindrosporlum on Q. rubra.
Susceptibility of Honeylocust Cultivars to Thyronectria Canker

Published: June 2022

Six cultivars of Gleditsia triacanthos were inoculated with the fungus Thyronectria austro-americana in May, July, September, and November. Branches were excised and examined in the laboratory the following spring. Small cankers and extended xylem discoloration were present, but wilting and dieback did not occur. The fungus persisted in the wood of every tree inoculated but caused cankers at only 20% of the inoculation sites. More cankers were present on trees inoculated in September and November than in May or July. Cankers were most frequent on 'Sunburst', less frequent on 'Moraine' and 'Skyline', and least frequent on 'Imperial', 'Holka', and 'Shademaster'.
A Nascent Technique for Cultivated Feature Selection using Evolutionary Computation Algorithms
Authors: Minocha Sachin , Singh Birmohan
Published: June 2022

Evolutionary computation algorithms are in recent trends for feature selection due to their efficient results as compared to traditional algorithms. The performance of the evolutionary computational algorithm completely depends upon the parameter (like population, number of generations) setting. Existing parameter setting techniques have been developed for specific algorithms. This paper designs a generic pre-processing technique that removes the redundant as well as irrelevant features from the initial given feature set. This work uses Kendall tau to find the non-redundant feature and the Kruskal Wallis for the relevant features. If Kendall tau is not able to select any non-redundant feature then mutual information gain is used to select significant features followed by the Kruskal Wallis to select relevant features. The designed technique has been analyzed on 4 evolutionary computation algorithms, Modified Binary Particle Swarm Optimization, Non-dominated Sorting Genetic Algorithm, Binary Grey Wolf Optimization, and Binary Whale Optimization Algorithm over 6 datasets by using accuracy, the number of features in selected subset, sensitivity, and specificity. The present technique improves the performance of each algorithm in terms of accuracy, sensitivity, and specificity by 1 % on average with a 10 % reduction in the selected feature subset proves the significance of the proposed technique.

HIGHLIGHTS

This work removes the redundant features from the initial population using Kendall’s tau and mutual information gain to reduce the initial population for any Evolutionary Computation (EC) algorithm

The relevant features that are highly correlated with class are added back to the initial population to maintain the optimal initial population

The performance validation has been done using four EC algorithms to show the significance of the work
