Countries of BRICS group on Forex market

Motivation: The globalization process has deepened the links between economies in the global socio-economic system. It has resulted in the shift of economic power from high developed countries to economies that have entered the path of fast socio-economic development, especially emerging markets. The emerging economies’ dynamic economic growth empowers the reduction of the development gap in relation to high developed economies. In the context of emerging markets, the special importance is dedicated to so-called BRICS countries. The share of BRICS countries in total world production as well as in total global trade, increases. The huge population and the GDP growth per capita make these economies the important markets nowadays. The financial market, especially the foreign exchange market becomes more and more important in the world economy. Aim: The aim of the paper is to examine the participation of the BRICS countries in the global foreign exchange market. The paper assumes that the increase of the BRICS group importance on the global markets does not correspond with the increase in the importance of these economies currencies on the Forex market. The BRICS group’s turnover in global foreign exchange turnover will be examined. In addition, the share of these currencies in the segments of particular types of transactions will be examined. Results: The importance of the BRICS group in the global economy is growing. However, this growth is not accompanied by growth of interest in currencies of this group on Forex market. The share of transactions concluded with the use of currencies of BRICS group was only 5% in 2019. Whereas, total currency turnover of the BRICS group countries was only 3% in 2019. The share of BRICS countries in individual market segments can be considered stable, yet insignificant.
Studies on Character Association and Casual Relationship of Seed Yield and Its Components in Early Maturing Genotypes of Pigeon Pea (Cajanus cajan L.)

The present investigation was undertaken with the objective to estimate the interrelationship of characters for seed yield in early maturing genotypes of pigeon pea (Cajanus cajan L.). The material consisted of twenty-one pigeon pea genotypes among which nineteen were early maturing genotypes received from ICRISAT (The International Crops Research Institute for the Semi-Arid Tropics), Hyderabad and two were local varieties collected from BNCA, AAU (Biswanath Chariali College of Agriculture, Assam Agricultural University), Jorhat. The experiment was conducted during kharif 2017-18 in randomized block design (RBD) with three replications at ICR farm, Assam Agricultural University, Jorhat. The estimates of genotypic correlations, in general, were found higher than the corresponding phenotypic correlation coefficients indicating strong association between two characters but the phenotypic values were lessened by the influence of environment. The seed yield per plant had shown significant positive correlation with plant height, pods per plant, pod length and harvest index both at phenotypic and genotypic level. Pods per plant and pod length had shown high positive direct effects on seed yield per plant at both genotypic and phenotypic level. At genotypic level, days to first flowering exhibited maximum positive direct effect on seed yield per plant. Pods per plant and pod length had shown high direct effects on seed yield/plant and hence direct selection for these traits may contribute towards improvement in seed yield/plant.
Life histories, ecological tolerance limits, and the evolution of geographic range size in Eucalyptus (Myrtaceae)

Current theories explaining variability in species geographic range sizes in plants tend to focus on how traits associated with either physiological tolerance limits or life histories are related to range size. In trees, aspects of both physiological tolerance (e.g. drought tolerance) and life history (e.g. life span and growth rate) are related to stem traits such as wood density and height relative to diameter. We examined how the evolution of stem traits is related to geographic range sizes in Eucalyptus at two spatial scales: across the Australian continent and within the wet forests near the east coast of Australia. Geographic range sizes were estimated from herbarium records. Stem trait data were collected from both natural populations and published sources. We used phylogenetically independent contrasts to test for evolutionary associations between stem traits and geographic range sizes. Across Australia, the evolution of stem traits conferring drought tolerance were not consistently associated greater range sizes. This was surprising since arid and semi-arid environments are geographically expansive. Within the eastern forests, the evolution of stem traits defining slow growing, competitively dominant life histories were associated with greater range sizes. These stem traits should confer both a capacity to disperse into previously unoccupied habitats and the ability to persist in habitats already occupied. Traits associated with physiological tolerance and life history had significant effects on the evolution of range sizes in Eucalyptus. However, we demonstrate that the impact of these traits on range size evolution depends on both environmental conditions and the scale at which these traits are examined.
Épocas de semeadura, densidades de plantas e desempenho vegetativo de cultivares de soja

The present research was carried out in Piracicaba, SP, Brazil, to evaluate vegetative performance of three soybean cultivars at two sowing dates, at five plant densities. The cultivars used were: IAC-17, IAC-12 and IAC-19, with early, semi-early and medium maturation, respectively, sown at the typical planting date and late date. Each cultivar was sown at densities of 10, 15, 20, 25, and 30 plants.m-1. Experimental plots with five rows spaced 0.50 m and 5.0 m long were randomized in blocks, using a factorial design (3 cultivars x 5 plant densities), with three replications. Plant final height, main stem diameter, number of nodes, and number of branches per plant were evaluated. Reduction of cultivars cycle for the late sowing date occurred mainly during the reproductive phase. Independently of the planting date, the increase in plant density, implyed in an increased final plant height and in decreasing main stem diameter and number of branches per plant. Number of nodes in the main stem was reduced with the delay of the planting date.
Paradigm Shifts in Habitat Ecology of Threatened Newfoundland Martens

Abstract We evaluated multiscale habitat selection by threatened Newfoundland (Canada) martens (Martes americana atrata) across landscapes composed of a range of habitat types to test the hypothesis that martens preferred mature (61–80-yr-old) and overmature (>80 yr) conifer stands. At both the landscape and stand scales, adult (≥1 yr) resident martens (n = 58, 92 yr-specific home ranges) selected for, or used in proportion to availability, a broad range of habitat types, including recent cuts ≤5 yr old, regenerating forest <6.5 m, precommercially thinned stands, and mature and overmature forest. Marten home ranges were not dominated by mature and overmature forest; median availability of mature and overmature forest within individual home ranges was only 30% (range = 11–76%). Age distributions were not different among martens with high, intermediate, and low quantity of mature and overmature forest in their home range; our data do not indicate that martens inhabiting ranges with little mature and overmature forest were compromising fitness. Habitat selection by martens in Newfoundland was more generalized than has traditionally been inferred, and we suggest that inherent landscape fragmentation, in combination with absence of many predators and competitors (i.e., ecological release), caused the Newfoundland marten to evolve to use a more generalized habitat niche than many mainland populations of American martens. We recommend that landscapes suitable for marten not exceed >29% younger aged forest. Maintaining resident martens in landscapes where forest harvesting is occurring requires prescriptions that recognize the highly fragmented nature of the natural landscape, the prevalence of mature and overmature forest, younger forests, avoided land-cover types, and human access.
Breeding and growth in laboratory-reared Microdeutopus gryllotalpa Costa (Amphipoda : Gammaridea)

Summary The tube-building amphipod Microdeutopus gryllotalpa Costa was successfully reared through several generations in the laboratory. Females produced young at six to eight day intervals, as many as eleven broods being produced during the two-month reproductive life of a single female in the laboratory. Brood numbers increased and decreased cyclically throughout the breeding period of any one female and a maximum of 58 young in a single brood was recorded. At 21°C young moulted at five-day intervals during their early instars and at about nine to ten day intervals in their later stages. Both sexes reached sexual maturity after the ninth moult, but males continued to differentiate morphologically after attaining sexual maturity.
A palaeospinacid shark from the Upper Triassic of south-west England

The fin spines of a new neoselachian shark are described from die Upper Triassic of Aust Cliff, Avon and Holwell, near Frome in Somerset. The spines are assigned to Palaeospinax rhaeticus sp. nov. This record adds to the known diversity of Upper Triassic marine vertebrates from Britain and extends the range of the palaeospinacid sharks into the Rhaetian.
A critical review of degradation assumptions applied to Mongolia’s Gobi Desert

Several assumptions about the levels and causes of rangeland degradation in Mongolia are widely accepted by a range of stakeholders. These assumptions have become important in terms of guiding strategies and policy directions. This paper provides a critical analysis of five widely-held assumptions about rangeland degradation in Mongolia to the more specific case of the rangelands of the Gobi Desert. These assumptions are: (i) there are too many animals; (ii) the relative increase in goat numbers has led to desertification; (iii) rainfall is declining; (iv) there is declining pasture biomass; and (v) Mongolian rangelands are degraded. Biophysical and social data from the Dundgobi and Omnogobi desert steppe areas suggest not all of these assumptions are supported all of the time, and that the processes upon which these assumptions are based are often more complex or dynamic than is commonly recognised. In designing policy and programs, more attention to these dynamics and complexities is needed.
Sensitive real-time PCR detection of Xanthomonas fragariae in strawberry plants

Xanthomonas fragariae, the causal agent of angular leaf spot on strawberry, is a quarantine organism in strawberry propagation material in the European Union. For the reliable screening of planting material for latent infections, a real-time PCR assay based on Taqman® chemistry for the detection of X. fragariae was developed. Primers and probe sequences were based on a DNA fragment amplified by a previously reported X. fragariae-specific technique. The sequence of this genomic fragment had no significant similarity with any published GenBank sequence. Specificity of the designed assay was tested with an extended range of X. fragariae collection strains and isolates, with other Xanthomonas spp. and with unidentified bacterial isolates from strawberry plants. A nested PCR, which until now was the reference method for sensitive detection in planta, cross-reacted with the reference strain of Xanthomonas campestris pv. campestris. In combination with an elaborated DNA extraction procedure, the Taqman® PCR enabled reliable detection down to 300 colony forming units in a 100 mg strawberry leaf sample. The assay offers a new tool for epidemiological research and for sanitary control of plant material with low level or latent infections of X. fragariae.
How specialized is the plant-pollinator association between Eucalyptus globulus ssp. globulus and the swift parrot Lathamus discolor ?

The swift parrot Lathamus discolor (Shaw) (Psittacidae) evolved from granivorous ancestors to become a specialized flower-feeder in a monotypic genus. Its reproduction is dependent largely on flowers of Eucalyptus globulus Labill. ssp. globulus (Myrtaceae), the birds migrating to breed within the natural distribution of this tree. This paper investigates the extent to which this dependence of L. discolor on E. globulus is mirrored by dependence of the tree on the bird. It was found that L. discolor carried significantly more eucalypt pollen within 22 mm of its bill tip than did the New Holland honeyeater, Phylidonyris novaehollandiae (Latham) (Meliphagidae), and that pollen was concentrated on the regions of the head of L. discolor that consistently contact stigmas. Larger pollen loads on L. discolor can be attributed to it consuming both pollen and nectar, while honeyeaters take nectar only. The short thick bill of L. discolor necessitates regular stigmatic contact while the long slender bills of honeyeaters are unlikely to contact stigmas as often in these bowl-shaped flowers. These factors suggest that L. discolor has a greater capacity to deposit pollen on stigmas of E. globulus than do honeyeaters. However, the characteristics of L. discolor that make it such an effective pollinator of E. globulus are also exhibited by a lorikeet (Psittacidae) that feeds on flowers of E. globulus. The association between E. globulus and L. discolor is therefore only moderately specialized because the flowers are also adapted to the more recently associated lorikeet and are almost certainly also pollinated by honeyeaters.
Chemical Composition and Antifungal Activity of Essential Oils of Some Aromatic Medicinal Plants Growing in the Democratic Republic of Congo

Abstract The chemical composition and the antifungal activity of essential oils from 15 aromatic medicinal plant species growing in the Democratic Republic of Congo have been studied. More than 15 constituents in an amount ≥ 0.1% were identified in each oil. 1,8-Cineole, α- and β-pinene, P-cymene, α-terpineol, camphene and limonene were prevalent constituents. The antifungal activity of these oils (5 μL per disc) was evaluated by the diffusion method. Results indicate that all oils from fresh plant materials exhibited an antifungal activity at different levels against Candida albicans, Candida tropicalis, Aspergillus niger, Trichophyton mentagrophytes and Microsporum canis. A high antifungal activity was found in the leaf oil of E. tereticornis (15–22 mm) followed by the leaf oils of Eucalyptus alba (14–17 mm), E. camaldulensis, E. citriodora, E. globulus, Cymbopogon citratus and Monodora myristica seed oil (11–17 mm) against selected yeasts, fungus and dermatophytes. The leaf oils of E. deglupta, E. robusta, Ocimum gratissimum and Aframomum stipulatum also showed a good activity against selected microorganisms (10–12 mm). The less active oils were those from E. saligna, E. propinqua and O. americanum leaves. No correlation between the amount of some major constituents and the antifungal activity was observed.

Autolysis of disintegrated cells of the yeast saccharomyces cerevisiae

Optimum conditions for autolysis of disintegrated cells of S. cerevisiae are at 50–53°C and pH 5.5; the process is terminated after 6 h. In the presence of sodium chloride (3–5%) the autolysis is complete after 5 h. The yield of autolysis of disintegrated yeast cells is about 70% of autolytic product per yeast dry weight. The product obtained after centrifugation, filtration and drying has very good sensoric and physical properties.
Impact of Macroeconomic Conditions, Industry Attributes and Firms Related Variables on Capital Structure: A Cross Industry Analysis

Purpose: This study is conducted to examine the main strength of firms’ specific variables, industry effects and macroeconomic conditions in predicting the capital structure choices of non financial listed companies of Pakistan Stock Exchange (PSX-100). Design/Methodology/Approach: To perform the study, a sample of twelve sectors covering a period from 2012 to 2017 is taken from PSX-100. Seemingly Unrelated Regression (SUR) model is applied to explore the capital structure choices. Results of study indicate that the short term debt plays a major part in designing the capital structure of listed companies of PSX-100. Findings: Macroeconomic conditions have been identified to cause an increase in financial distress and costs of debt unanimously. The financial distress and costs are significant in financial market developments for a time horizons. Implications/Originality/Value: The development in financial markets can have an opportunity to increase the choice of capital structure of firms optimistically. It is explored that source of capital choice seems to decrease in agency behavior and risk due to refinancing. The less agency problem and less risk provide better choice of debt and future growth to the financial market. The growth environment is life blood of financial market and economy.
Production of High Ethanol Concentrations from Glucose Using a Vertical Rotating Immobilized Cell Reactor of the Bacterium Zymomonas mobilis

Long‐term continuous ethanol production of up to 80 g.l with a volumetric ethanol productivity of 63 g. l. h was maintained for more than 72 days using a Vertical Rotating Immobilized Cell Reactor of the bacterium Z. mobilis. Continuous production of higher ethanol concentration was unsuccessful due to an inhibition of cell growth by long exposure to high ethanol concentrations. However, ethanol concentration as high as 120g. l and volumetric ethanol productivity of 13g. l. h were achieved in a repeated‐batch fermentation system using the same bioreactor. By a simple washing operation at the end of each run, immobilized biomass could be effectively regenerated and used to carry out more than 10 successive fermentation cycles.
Heavy metal pollution and macrobenthic assemblages in soft sediments in two Sydney estuaries, Australia

The influence of heavy metals (copper, lead and zinc) associated with urban runoff, on assemblages of macrofauna in intertidal soft sediments was studied in two estuaries in the Sydney region. The patterns of distribution and abundance of fauna and assemblages was found to vary significantly at several spatial scales: within bays in an estuary, between bays within an estuary and between bays from different estuaries. Significant differences were found in concentrations of heavy metals in sediments, but there was very little difference among bays in other environmental variables: grain-size characteristics and organic matter content of sediments. Bays polluted by heavy metals had significantly different assemblages to unpolluted bays, were generally less diverse and were characterized by an order-of-magnitude greater abundance of capitellids, spionids, nereids and bivalves. Unpolluted bays had greater abundance of crustaceans and several polychaete families, including paraonids and nephtyids and were generally more diverse. There was a significant correlation between patterns of assemblages and concentrations of heavy metals, but not with other environmental variables.
The Influence of Blended family Structures on Socio-emotional Development of Pre-priamry School Learners in Ganze Sub-county, Kilifi County, Kenya

Families provide a conducive environment that necessitates the acquisition of self-esteem, self-confidence, and self-efficacy amongst learners in pre-primary schools. However, pre-primary school learners have manifested and continue to manifest instances of low self-esteem, low self-confidence, and self-efficacy levels. This study sought to assess the influence of contemporary blended family structures on the socio-emotional development of pre-primary school learners. The study was guided by the family systems theory. The study adopted a mixed methodology and thus applied concurrent triangulation research design. Qualitative data were analyzed thematically along the objectives and presented in narrative forms. Quantitative data were analyzed descriptively using frequencies and percentages and inferentially using Pearson’s Product Moment Correlation Analysis in Statistical Packages for Social Sciences (SPSS 23) and presented using tables. The study established that pre-primary school learners manifest instances of low self-esteem, low self-confidence and low self-efficacy. The study also established that there are different dimensions of blended family structures that influence socio-emotional development, that is, self-esteem, self-confidence, and self-efficacy, of pre-primary school learners. Thus, the study recommends that parents who are in blended family structures should adopt the mechanism of enhancing the socio-emotional development of their children. The government and other stakeholders should provide necessary support meant to help such families improve the socio-emotional development of their children. Government agencies should create funds and kitties meant for the upkeep of children who are orphans and vulnerable.
Comparative Analysis of High‐Molecular‐Weight Glutenin Subunit Composition in Various Triticum Species

Variation in high-molecular-weight glutenin subunit composition amongst Triticum durum cvs. of different origins was investigated by SDS-PAGE and compared with that reported for T. dicoccum and T. aestivum. Tetraploid wheat collections (408 cvs.) were found to carry nearly twice as many Glu-A1 and Glu-B1 alleles as a hexaploid wheat sample of comparable size. In each of the taxa considered, allelic variation at the Glu-B1 locus was markedly greater than that observed for Glu-A1. However, because all the Glu-B1 subunits so far discovered exhibit a restricted and distinctive mobility range during. SDS-PAGE, it is suggested that they are derived from a single source, possibly from Aegilops searsii. Most durum cvs. carried a ‘null’Glu-A1 allele and therefore fewer subunits than dicoccums and common wheats. It is argued that differences in the frequency of occurrence of ‘null’Glu-1 alleles between taxa probably resulted from random samplings made by early agriculturalists and breeders, rather than from an inherent tendency of polyploid wheats to suppress the activity of “redundant” genes.
