Efecto de la aplicación del H 2 O 2 durante la interacción ‘Grande naine’- Mycosphaerella fijiensis

In Musa spp. considerable economical lost are cause by Mycosphaerella fijiensis infection around the world, that is why the study of the pathosystem constitute a priority. However, the main mechanisms activated in banana after infection are still unknown and are a limitation for a better understanding of this complex relationship. The objective of this study was to determine the effect of hydrogen peroxide (H 2 O 2 ) application, on leaves of ‘Grande naine’ plants, on black leaf streak disease development (BLSD). For this purpose, the first three open leaves of banana plants were inoculated with the monoascosporic isolate of M . fijiensis CCIBP- Pf -83. At three days post-inoculation different H 2 O 2 concentrations (10, 20, 30 and 40 mmol l -1 ) were sprayed to these plants as well as to non-inoculated ones. During the time course of the experiment for inoculated, sprayed plants and for control plants (infected with M. fijiensis ) epidemiological variables as well as the area of necrotic lesions at 49 dpi were measured. The findings of this analysis showed that the early application of H 2 O 2 have influence on the BLSD development. Keywords: banana, black leaf streak disease, hemibiotrophic, hydrogen peroxide
Impact of supply chain management strategies on the performance indicators of small and medium-sized businesses

Abstract — The study considers the impact of supply chain management strategies on the performance of small and medium-sized businesses. It is shown that developed 4PL operators are economic integrators of countries dominated by small and medium-sized enterprises. The study deals with the data of the Federal Republic of Germany, China, the Republic of Kazakhstan, and the Russian Federation. The research hypothesis has been statistically confirmed: higher-level business models of supply chain management (for example, 4PL) are used in countries where there are significant investments in information and communication technologies. This positively affects the turnover of small and medium-sized enterprises. Logistics providers are supply chain integrators. It has been established that the higher the share of small and medium-sized businesses in the country's economy, the more developed the supply chain management system is. It has been shown that developed small and medium-sized businesses are integrated into a single management system with the help of 4PL operators; this makes it possible to increase the efficiency of both small and medium-sized enterprises and logistics operators. The scheme for increasing the efficiency of small and medium-sized businesses based on e-logistics has been presented.
Performance assessment of a concrete railway bridge by diagnostic load testing

Diagnostic load testing can be a suitable method for condition assessment of existing bridges. This paper presents the evaluation of a concrete railway bridge built in the 1940s based on diagnostic load testing. The test was the outcome of a visual inspection and preliminary theoretical analysis that found the bridge to be in unsatisfactory condition. Unlike the other possibilities that infrastructure management bodies have in such situations, for example, structure replacement, traffic reorganization, closure of the bridge, etc., diagnostic load testing is a low cost and quick method that indicates the bridge response to real traffic load. The paper describes the test plan and implementation covering the static and dynamic load tests. The experimental methods comprise superstructure displacements measurement, strain measurement on concrete and reinforcement and determination of bridge dynamic parameters. The obtained test results analysis enabled more accurate diagnosis of the actual bridge condition. The bridge demonstrated satisfactory load bearing capacity and response to real service load in terms of registered levels of displacement and strain and proper dynamic performance.
Diverse communities of Bacteria and Archaea flourished in Palaeoarchaean (3.5–3.3 Ga) microbial mats

Limited taxonomic classification is possible for Archaean microbial mats and this is a fundamental limitation in constraining early ecosystems. Applying Fourier transform infrared spectroscopy (FTIR), a powerful tool for identifying vibrational motions attributable to specific functional groups, we characterized fossilized biopolymers in 3.5–3.3 Ga microbial mats from the Barberton greenstone belt (South Africa). Microbial mats from four Palaeoarchaean horizons exhibit significant differences in taxonomically informative aliphatic contents, despite high aromaticity. This reflects precursor biological heterogeneity since all horizons show equally exceptional preservation and underwent similar grades of metamorphism. Low methylene to end‐methyl (CH2/CH3) absorbance ratios in mats from the 3.472 Ga Middle Marker horizon signify short, highly branched n‐alkanes interpreted as isoprenoid chains forming archaeal membranes. Mats from the 3.45 Ga Hooggenoeg Chert H5c, 3.334 Ga Footbridge Chert, and 3.33 Ga Josefsdal Chert exhibit higher CH2/CH3 ratios suggesting mostly longer, unbranched fatty acids from bacterial lipid precursors. Absorbance ratios of end‐methyl to methylene (CH3/CH2) in Hooggenoeg, Josefsdal and Footbridge mats yield a range of values (0.20–0.80) suggesting mixed bacterial and archaeal architect communities based on comparison with modern examples. Higher (0.78–1.25) CH3/CH2 ratios in the Middle Marker mats identify Archaea. This exceptional preservation reflects early, rapid silicification preventing the alteration of biogeochemical signals inherited from biomass. Since silicification commenced during the lifetime of the microbial mat, FTIR signals estimate the affinities of the architect community and may be used in the reconstruction of Archaean ecosystems. Together, these results show that Bacteria and Archaea flourished together in Earth's earliest ecosystems.
Complete mitochondrial genome of white-backed woodpecker Dendrocopos leucotos (Piciformes: Picidae) and its phylogenetic position

Abstract The white-backed woodpecker (Dendrocopos leucotos) is an ecologically important bird in Eurasian forest ecosystems. In this study, the complete mitochondrial genome of the species was sequenced using next-generation sequencing technology. The genome was 16,838 bp in length, consisting of 13 protein coding genes, two rRNAs, 22 tRNAs, a non-coding control region and a repeat region. Phylogenetic analysis using available complete mitochondrial genomes of the Coraciimorphae supported the monophyly of the Piciformes. The complete mitochondrial genome of D. leucotos will be a useful genetic resource for population genetics, phylogenetic analysis and conservation of the species.

Determination of drying kinetics and quality parameters for drying apricot cubes with electrohydrodynamic, hot air and combined electrohydrodynamic-hot air drying methods

Abstract In this study, the effects of the electrohydrodynamic (EHD) drying method with needle and wire, the hot air method and a combination of the EHD-hot air methods on the drying kinetics, color, rehydration ratio and scanning electron microscope images of apricot samples were investigated. In addition, the experimental drying data were modeled using ten different mathematical thin layer drying models. It was determined that the rehydration ratio values of the samples dried with the combination of EHD and hot air were generally higher than the rehydration ratios of the samples dried with hot air or EHD only. Samples from all the drying methods were compared with fresh samples; the color parameters were affected, and scanning electron microscopy images revealed the different physical changes in the microstructure of the products. As a result, it is determined that EHD technology can be used as an alternative drying method suitable for apricot samples.
What can research organizations learn from their spin-off companies? Six case studies in the water sector

Spin-off companies are generally considered a promising vehicle for developing academic knowledge into products that are ready for the market. In this paper the authors explore under what circumstances spin-off companies can serve as a source of knowledge for the research organization from which they originate. The paper brings together literature from different academic fields to construct an analytical framework for investigating knowledge feedback mechanisms between spin-off companies and their parent research organizations. The authors illustrate the application of this framework in six case studies of parent–spin-off couples in the water technology sector. These case studies show that the interaction with spin-off companies can yield important cognitive benefits for the academic research process, such as an improvement of the research agenda and new insights about the practical operation of theoretical models and technologies. These benefits were facilitated mainly by staff exchange, collaborative research and personal contacts.
Genome Analysis of Two Bacterial Strains Isolated from Diseased Freshwater Sponge Reveals the Probable Cause of Its Joint Domination in Microbial Community

Endemic freshwater sponges (Demosponges, Lubomirskiidae) dominate in Lake Baikal 12 and are multicellular filter-feeding animals represent a complex consortium of many species of 13 eukaryotes and prokaryotes. In recent years, mass disease and death of the L. baicalensis have been 14 an urgent problem of Lake Baikal. The etiology and ecology of these events remain unknown. 15 Bacteria in microbiomes of diseased sponges of the families Flavobacteriaceae and Oxalobacteraceae 16 were dominant. Both species are opportunistic pathogens common for freshwater ecosystems. The 17 aim of our study is to analyze the genomes of strains Janthinobacterium sp. SLB01 and Flavobacterium 18 sp. SLB02, isolated from diseased sponges to identify the reasons for their joint dominance. The first 19 one attacks the other cells using type VI secretion system, suppress gram-positive bacteria with 20 violacein pigment and regulate its own activity via quorum sensing. It makes the floc and strong 21 biofilm by exopolysaccharide biosynthesis and PEP‐CTERM proteins expression. The second one 22 utilizes the fragments of cell walls produced of polysaccharides. Named two strains have noticeable 23 difference in carbohydrates acquisition. We described the possible way of joint occupation of 24 ecological niche into freshwater sponge microbial community. This study expands understanding 25 about symbiotic relationship of microorganisms with freshwater Baikal sponges. 26
Genetics of brain age suggest an overlap with common brain disorders

Numerous genetic and environmental factors contribute to psychiatric disorders and other brain disorders. Common risk factors likely converge on biological pathways regulating the optimization of brain structure and function across the lifespan. Here, using structural magnetic resonance imaging and machine learning, we estimated the gap between brain age and chronological age in 36,891 individuals aged 3 to 96 years, including individuals with different brain disorders. We show that several disorders are associated with accentuated brain aging, with strongest effects in schizophrenia, multiple sclerosis and dementia, and document differential regional patterns of brain age gaps between disorders. In 16,269 healthy adult individuals, we show that brain age gap is heritable with a polygenic architecture overlapping those observed in common brain disorders. Our results identify brain age gap as a genetically modulated trait that offers a window into shared and distinct mechanisms in different brain disorders.
Cyber Attacks on Precision Time Protocol Networks—A Case Study

The IEEE 1588 precision time protocol (PTP) is used by many time-sensitive applications and systems, as it achieves sub-microsecond time synchronization between computer clocks. However, a PTP network is vulnerable to cyber-attacks that can reduce the protocol accuracy to unacceptable levels for some or all clocks in a network with potentially devastating consequences. Of particular concern are advanced persistent threats (APT), where an actor infiltrates a network and operates stealthily and over extended periods of time before being discovered. This paper investigates the impact of the most important APT strategies on a PTP network, i.e., the delay attack, packet modification or transparent clock attack, and time reference attack, using a fully programable and customizable man in the middle device, thereby considering the two most popular PTP slave daemons PTPd and PTP4l. In doing so, it determines suitable attack patterns and parameters to compromise the time synchronization covertly.
STOCHASTIC ORDERING OF LIFETIMES OF PARALLEL AND SERIES SYSTEMS COMPRISING HETEROGENEOUS DEPENDENT COMPONENTS WITH GENERALIZED BIRNBAUM-SAUNDERS DISTRIBUTIONS

In this paper, we discuss stochastic orderings of lifetimes of two heterogeneous parallel and series systems with heterogeneous dependent components having generalized Birnbaum–Saunders distributions. The comparisons presented here are based on the vector majorization of parameters. The ordering results are established in some special cases for the generalized Birnbaum–Saunders distribution based on the multivariate elliptical, normal, t, logistic, and skew-normal kernels. Further, we use these results by considering Archimedean copulas to model the dependence structure among systems with generalized Birnbaum–Saunders components. These results have been used to derive some upper and lower bounds for survival functions of lifetimes of parallel and series systems.
The Characterization of Local Clay from Anambra State Nigeria for Its Potential Applications in the Production of Ceramic Whitewares

Local clay deposits from Ukpor in Nnewi South Local Government Area of Anambra State were characterized for its potential applications in the production of ceramics whitewares. XRF analysis of the clay revealed that it has high silica and alumina contents with some flux oxides. XRD analysis also revealed that of all the minerals present in the clay, quartz has the highest constituent followed by kaolinite and rutile. FT-IR analysis revealed that the bands corresponds to 3500 cm -1 to 4000 cm -1 indicating the presence hydroxyl groups (OH) and Si-O symmetry vibration stretch at 1206.207 cm which confirmed the kaolinite structure of the clay. The SEM study showed a finely distributed uniform surface with isolated patches of granulated texture which explained the physical behaviour of the clay. The EDS spectrum of the formulated fired Ukpor clay indicated the presence of O, Al, K, Ca, K, Fe, and Si. The study revealed that an increase in the firing temperature and feldspar contents of the clay increases its bulk density, while the apparent density decreases with increase in Original Research Article Nnaneme et al.; AJOCS, 8(2): 22-33, 2020; Article no.AJOCS. 60419 23 temperature. Apparent porosity showed that there was a decrease from 25% to 3%, and the water absorption increases with increase in the silica content and decreases with temperature and feldspar increase. The shrinkage increases with the increase in temperature. The results concluded that the clay sample could be utilized as an industrial raw materials for the production of ceramic whitewares.
Immobilized lysozyme onto bacterial cellulose nanofibers as active and reinforcing agent of sodium caseinate based films: physical characteristics and antimicrobial activity

The aim of this research was to compare the effect of free and immobilized Lysozyme on the physicochemical and antimicrobial properties of sodium caseinate (SC) based active films. Lysozyme was immobilized onto bacterial cellulose nanofiber (BCNF) and decreasing of its activity was approved after immobilization. Free and immobilized enzymes were incorporated into SC films at the concentrations of 0.5 and 1 mg.100ml-1 and the films were characterized. Addition of BCNF and lysozyme diminished significantly (p˂0.05) the moisture absorption and water vapor permeability of SC films and immobilized enzyme had higher effect than free enzyme on decreasing of these parameters. The tensile strength and Young’s modulus were increased and elongation to break was decreased by incorporation of BCNF. An adverse effect was observed for lysozyme addition but the effect of immobilized enzyme on the weakening of tensile properties was lower than free lysozyme. According to XRD results, the crystallinity of films increased by incorporation of BCNF and lysozyme. However, the immobilization reduced the crystalline regions of BCNF. Antimicrobial activity of lysozyme increased after immobilization and SC films containing immobilized enzyme exhibited considerable activity against Gram-positive bacteria S.aureus, L.monocytogenes. Gram-negative bacteria E.coli, Y.enterocolitica, mold of A.niger and yeast of S.cerevisiae.
Subjective Well-Being and Its Relation to Academic Performance among Students in Medicine, Dentistry, and Other Health Professions

Subjective well-being is defined as a person’s cognitive and affective evaluations of his or her life. This study aims to investigate the differences in the domains of subjective well-being based on gender, type of school, and academic performance. Additionally, the study aimed to determine the factors (socio-demographic variables, including the academic performance of the students) that are predictive of subjective well-being. Subjective well-being was assessed using a questionnaire which included the Satisfaction with Life Scale (SWLS), which measured the respondent’s life satisfaction, the Scale of Positive and Negative Experience (SPANE), which consisted of six positive and negative emotions, and, lastly, the Flourishing Scale (FS), which measured the respondents’ self-perceived success. Data were collected, transformed into a linear scale, and exported into SPSS version 24, where t-tests, one-way analysis of variance, Pearson correlation, and stepwise regression were performed. Of the total of 535 participants, the majority were females (383 = 71.6%) and studying in a school of medicine (31.8%). With respect to the SWLS and FS, a significant difference was reported among students based on the type of school and their academic performance (p < 0.05). While comparing the differences in the SPANE, a significant difference was recorded based on academic performance. Among the domains of subjective well-being, only the SPANE showed a significant association with academic performance. Greater subjective well-being correlates with higher academic performance, indicating that subjective well-being is an important aspect of a student’s academic life; provisions can be made by paying more attention to those who showed poor academic performance during and at the end of each semester.
