Soil as a subgrade foundation under embankment construction often creates problems in terms of stability and settlement. Therefore, it needs improvement by using preloading embankment. This article presents the investigation of pile behavior towards two scenarios of abutment construction using Plaxis 3D, a three- dimensional finite element program. The use of two scenarios of analysis was Method A. The abutment construction phase conduct without using a preloading embankment, and Method B, where a preloading embankment constructs before the abutment construction. The case study location at the Lembak bridge. Compare the analysis results with the measured data. Results showed that Method A and Method B's pile deflection yielded four times and one point six times larger than the measure data, respectively. Hence, it indicates that Method B recommends for future construction of bridge abutment.

Published: April 2021

Floods occur almost every year in a number of areas in the floodplain of Kali Welang. The floods have caused loss of materials and lives. Assessment of the vulnerability is essential for policy making in non-structural treatment of floods. The objective of this paper is to compute and elaborate the flood vulnerability index in local scale to assess conditions that affect the magnitude of flood hazards. This study identifies and evaluates the Flood Vulnerability Index (FVI) of an area by considering the factors of area’s exposure to floods, flood susceptibility, and flood resilience. The Analytic Hierarchy Process (AHP) is used to formulate the weights of each component. The values of the components were collected from interviews with policy makers from relevant governmental agencies. The inputs for the AHP were collected from the respondents in a questionnaire survey. This study selected 18 relevant indicators. The FVI results show very high vulnerability in local scale in one village and high vulnerability in other six villages. The results of this study can be used to construct non-structural strategies in flood mitigation by enhancing community’s resilience toward the flood. In addition, the results can be used for policy making process in spatial urban planning.

Development of large-fruited bird cherry cultivars on the basis of wild species for northern and eastern regions of Russia
Authors: Simagin V. S. , Lokteva A. V. 
Published: April 2021

Bird cherry occupies a special place among stone fruit plants. Its fruits, collected in nature, were widely used by local communities, native to regions with severe climate. Development of new bird cherry cultivars, well adapted to such environments, with stable productivity and larger fruit, is a necessity.Crossings were performed involving the most large-fruited genotypes of Prunus padusL. and P. virginianaL., selected during the study of their intraspecific variability and interspecific hybrids. A number of hybrids were identified for their considerably higher fruit weight than that of both parents. Crossing the most large-fruited hybrid cultivars ‘Pamyati Salamatova’ and ‘Cherny blesk’ with large-fruited P. padussamples from Bondarev No. 11-2-64, No. 11-2-70, No. 11-2-76, and P. virginianasamples No. 1-14-1 and No. 10-5-2, produced many hybrids with a fruit weight gain of 20–50% over the parent with the largest fruit. It can be explained by the polygenic nature of fruit weight inheritance. The samples with the largest fruits had an average fruit weight of 1.4–1.5 g and maximum weight of 1.8–1.9 g. Many of them combined large fruit size with good quality and high productivity. Brief descriptions of fruit traits are presented for several hybrids. Suppositions are made about the prospects of further breeding for the large fruit trait on the basis of the same genetic sources or with the use of other sources of large fruit size in hybridization.Thus, preliminary selection of the best genotypes in nature and in introduced populations, followed by their crossing within their own species and with other species, makes it possible to produce genotypes with larger fruits than the average fruit size for a population and considerably larger than in their parents. It would help to develop bird cherry cultivars, well adapted to local conditions, for amateur and industrial horticulture under different climate conditions of Russia.

Authors: Lezin M. S. , Asbaganov S. V. 
Published: April 2021

Background.Studying genetic polymorphism of the Prunus pumilaL. representatives with a wide range of variability in morphological characters will make it possible to identify promising genotypes with high combining ability for hybridization.Material and methods.The study covered 39 genotypes from the Chelyabinsk cultivated population and 6 genotypes from Khakassia, with extreme or intermediate expressions of such characters as fruit size, color and shape; stone shape and surface structure; leaf blade serration and shape; plant habitus, and some others. Genetic distances were calculated using the data matrix for binary states of presence (1) or absence (0) of amplified fragments with the Past Program (Gower). The UPGMA dendrograms were obtained in TREECON (version 1.3b).Results and discussion. The selected 5 ISSR and 2 RAPD primers demonstrated their effectiveness in detecting genetic polymorphism in the studied accessions. In individual cases, a weak connection of separate markers with leaf blade edge serration, stone surface structure, plant habitus, and geographic origin of the genotype was detected. Concurrent inclusion of all primers and genotypes in the cluster analysis failed to group the studied P. pumilasamples into clades according to the presence/absence of any traits, which may attest to their close genetic affinity. An independent clade with reliable bootstrap support (100%) was formed only for the genotypes of the taxonomically close sp. P. tomentosaThunb., analyzed as an external group. Moreover, this clade manifested (with the 86% reliability of bootstrap support) differences between the hybrid genotypes of P. pumila× P. tomentosa(F3) and the genotype of P. tomentosa. Parent pairs promising for fruit quality and shrub shape improvement through breeding were identified using the produced indices of genetic distinction.

Background.The aim of the research was to identify barley germplasm accessions with the minimum and maximum content of β-glucans in their grain in combinations with other improved useful traits.Material and methods.The material for analysis were 18 hulled and 8 naked barley accessions of various ecogeographic origin from the collection of the N.I. Vavilov AllRussian Institute of Plant Genetic Resources (VIR), which were grown under the conditions of Eastern Siberia in 2016–2018.Results.Hulled accessions yielded grains with β-glucan content from 3.18 to 4.51%; naked ones, from 3.18 to 5.21%. According to the minimum value of the studied qualitative trait (3.18–3.43%), cultivars of Siberian breeding were identified: ‘Mayak’ (k-29622, Krasnoyarsk Territory) and ‘Tarsky 3’ (k-30719, Omsk Province), plus cv. ‘AC Albright’ (k-30599, Canada); according to the maximum value (5.06–5.21%), the naked accessions Nudum 155 (k-13328, Ukraine) and ‘Nudum 95’ (k-31125, Chelyabinsk Province). The highest protein content in grain (16.63–18.36%) was found in the accessions Nudum 155, Nudum 7566 (k-29453, Kyrgyzstan) and ‘Nudum 95’. The accessions Nudum 155 and ‘Nudum 95’ were characterized by combined high contents of β-glucans and protein in their grain. Early maturity and increased productivity were shown by the cultivars ‘Tarsky 3’, ‘Kolchan’ (k-31039, Altai Territory), ‘Zolotnik’ (k-30845, Altai Territory), ‘Abalak’ (Krasnoyarsk Territory, Tyumen Province), and ‘AC Albright’ (Canada). A significant positive relationship was found between the content of β-glucans and the weight of 1000 grains in both forms of barley.Conclusion.According to β-glucan content combined with other valuable characteristics in grain, the accessions ‘Mayak’, ‘Tarsky 3’ and ‘AC Albright’ are of interest for the improvement of fodder cultivars, while ‘Nudum 95’ and Nudum 155 are promising for breeding for food.

Comment on Strongly Preirresolute Topological Vector Spaces
Authors: RAM Madhu , ELAGAN Sayed K 
Published: April 2021

Let (X, =) be a topological space. A subset A of X is called
pre-open if A ⊆ Int(Cl(A)). Let P O(X) denote the family of all pre-open
sets in X. In general, P O(X) does not form a topology on X. Furthermore, in topological vector spaces, it is not always true that P O(L) forms
a topology on L where L is a topological vector space. In this note, we
prove that the class of strongly preirresolute topological vector spaces is
that subclass of topological vector spaces in which P O(L) forms a topology and thereby we see that all proved results in [5] concerning strongly
preirresolute topological vector spaces are obvious.
Use of LANDSAT-TM data in mapping of the Siwalik deposits, Nepal
Authors: Duvadi A. K. , Rimal L. N. , Nepali D. , Singh S. 
Published: April 2021

Satellite data are exploited to study the Butwal, Hetauda, Bagmati River and Trijuga sections of the Siwaliks and the results of the investigations are discussed. Remote Sensing data deliver information on lithological units, orientation of the strata (bedding as iron plates, strike directions) and tectonic structures (strong lines and other features) of the region.
The data supplemented by multicolour satellite images are valuable assets in deciphering the geology of an area. The satellite LANDSAT-TM data of two false colour composites of the Bagmati and Trijuga River area of the Sub-Himalayan (Siwalik) region show interesting tonal and morphological (topographical and textural) differences. Such variations can be attributed to lithological discrepancies among the geological formations of the area.
At least three different lithological units of the Siwaliks are recognised. They are fine, medium and coarse grained elastic deposits corresponding to the three fold divisions (Lower, Middle and Upper) of the Sub-Himalaya. The three lithological units are morphologically related to the smooth, rugged and dissected terrains. Shifting up of the Siwalik range near about I2 km northeast of Lahan, active fault alignment along with MBT (north of Gaighat), Bhabar Zone (southern part of the foothills of the Siwaliks), Dun Valley (Hetauda) are prominent features observed in the TM-scenes.
Rivers originating in the middle mountains of Lesser Himalaya like Trijuga, Bagrnati, Rapti, Tinau and Banganga drain through the Siwaliks crossing the major structure MBT suggesting an antecedent river type. Other streams originating in the Siwaliks and flowing southward are obsequent and subsequent.
Indicator plants as guide to mineralisation in parts of Sikkim-Darjeeling Himalaya, India
Authors: Sen Purnendu 
Published: April 2021

Systematic geobotanical and biogeochemical studies have not been attempted in any of the basemental prospects in the eastern Himalaya. The conventional geochemical soil and bedrock sampling in this rugged terrain has been proved to be abortive due to steep surface gradient, soil creep, landslide and excessive precipitation. As a supplement to conventional geochemical prospecting, an orientation survey on the population and growth habits of plants may help in the selection of plant species for prospecting. The chemical analyses of systematically sampled plants may possibly lead to the identification of indicator plants which are likely to act as direct guide to mineralisation in the substrate. With these ideas in view, the Pb-Zn-Cu deposit of the Bhotang mine near Rangpo, Sikkim and Pb-Zn-Cu mineralised zone of Malkhola Block, Gorubathan in Darjeeling district, West Bengal have been selected for such studies so as to find out the possible correlation of the elemental concentrations in the substrate and plants growing over them and subsequently delineating the indicator plants for certain elements. The presence and distribution pattern of such indicator plants in adjoining areas or elsewhere may help to detect zones of mineralisation which may not have any surface expression.
The polymetallic Pb-Zn-Cu deposit of the Bhotang mine, Rangpo, Sikkim the mineralisation occurs in the form of veins, disseminations, patches and lenses in chlorite schist and phyllite. Five zones of mineralization have been delineated from southwest to northeast and it has been observed that the chalcopyrite-rich zone increases towards the southwestern direction and galena predominates over the other sulphides in the northeastern part.
The leaves, twigs and roots of different plant species occurring in the hill above the Bhotang mine have been systematically sampled and analysed for basementals and associated trace elements. The ashes of several plant species, viz. Dioscorea batatas, Eupatorium odoratum, Lantana camara, Pteris longifolia, Adiantum sp., grass with hard intemode, grass without hard internode and locally known Koirala (Family: Verbenaceae) show anomalous concentrations of Pb, Zn and Cu and other trace elements. A rare variety of plant, locally known as Koirala (Family: Verbenaceae) grown on the hanging wall side of the lode and Pityrogramma sp., an extremely rare variety of fern, have yielded very high values of Cu Pb and Zn which designates them as possible indicator plants for basemetal mineralisation in this terrain.
The study has thus indicated that Koirala and pytyrogramma sp. In Rangpo area, and Plumbago zeylanica and Micana scandens in Gorubathan area, Darjeeling hold good promise as local indicator plants for identifying zones of basemental mineralisation.
