Abstract
The vast territory of Indonesia stretches along the equator. Indonesia, which has a dynamic tropical rainy climate, needs fast and accurate weather information for various activities on land, sea, and air. Therefore, it is necessary to have information on the available weather that covers the entire area on an ongoing basis. Weather data information can be obtained quickly from remote sensing satellites. Where the advantage of geostationary satellites has wide enough coverage of the earth’s appearance where weather information can easily be obtained. Since 2015, the Himawari-8 satellite has been used as a weather satellite by the Japan Meteorological Agency (JMA). There are several methods of data distribution, one of which is Himawari Cast that suitable for use by ground stations. Since 2016, the National Institute of Aeronautics and Space of Indonesia (LAPAN) has received Himawari-8 data using the Himawari Cast method via the Pekayon Ground Station. Himawari data sent by the telecommunications satellite JCSAT-2B is carried out every 10 minutes. Therefore, reliable ground station equipment is needed because it works almost all the time. Therefore, a backup reception system was built that functions as a system that is ready if one day the main receiving system fails. This paper contains the design, installation, and integration of devices from a backup system made at Pekayon ground station to receive Himawari data. Not only from the hardware side that was developed but also from the software side that can generate data regarding cloud information from Himawari-8 data.

Authors: Bikbaev I G 
Published: October 2022

Abstract
The work presents a systematic and phytosociological analysis of rare threatened vascular plants of the wetlands in the Republic of Bashkortostan. The work considers the plants listed in the Bern Convention list, Red Data Books of the Republic of Bashkortostan and the Russian Federation, as well as IUCN Red List of Threatened Species. In Bashkortostan, the greatest number of rare mire species is represented by the family Orchidaceae, and the second place belongs to the family Cyperaceae. The communities of low sedge-moss minerotrophic fens of the alliance Caricion davallianae and oligo-minerotrophic mires of the alliance Sphagno-Caricion canescentis are the richest in rare species. Less rich in rare species are mesotrophic paludified forests and shrublands with sedge-moss communities of the alliance Betulion pubescentis and oligotrophic shrub-sphagnum bogs of the alliance Vaccinio uliginosi-Pinion sylvestris. The communities of eutrophic mires dominated by high sedges, shrubs, trees, as well as water communities located within mire complexes have the lowest diversity of rare species.

Published: October 2022

Abstract
The identification of methods for uranium immobilization is important for decision-making on remediation of contaminated areas. Here we investigate the degree of uranium binding on peat sorbents chemically modified using humic acids (HA), zero-valent iron (ZVI), and aqueous ferric chloride. The peat was sampled in the territory of the sludge storage of low-radioactive wastes. In the laboratory, the uranium adsorption on natural peat reaches the maximum values of 86% after 8 hours in comparison with the 92% after 30 min on HA modified peat and 88.8% after 2 hours on aqueous ferric chloride modified peat. The improvement of the peat sorption capacity was confirmed within the three months field experiment using HA and ZVI. The results of the sequential extraction procedure confirm the participation of both modifiers in the processes of uranium sorption.

Abstract
The subject of the study are three raised bogs located in the vicinity of the Sredneeniseyskya monitoring station of the V. N. Sukachev Institute of Forest SB RAS (Krasnoyarsk Territory), which were affected by fires in different periods of time. It is shown that the bogs differed in thickness and age of peat, the amount of accumulated macro charcoal particles along the soil profiles. The age of the lower peat horizons showed that bog formation in the studied area started at different times: from the second half of the Boreal period of the Holocene to the Subatlantic period. The content of charcoal showed that the pyrogenic activity during the Holocene was different. The morphological structure and chemical properties of peat soils have changed in the pyrogenic horizons of all the sites, compared with non-pyrogenic ones. They are depleted of carbon and nitrogen, enriched in ash elements. The content of microbial biomass (MB) and basal respiration (BR) rate is low due to a lack of organic matter, the microbial trophy is disturbed, and the restoration of microbial activity is extremely slow. The main role in the transformation of pyrogenic horizons was assigned to bacteria, while fungal activity was significantly lower.

Abstract
The peatlands in the northern hemisphere accumulated substantially more atmospheric carbon (C) during the Holocene than other terrestrial ecosystems. In this study we applied a multi-proxy record to distinguish variations in dynamics of two peatlands in the boreal belt (raised bog) and the forest-tundra ecotone (palsa mire) in Central Siberia. Carbon and nitrogen content in peatland soils and their stable isotope composition δ13C and δ15Μ) were used to trace likely changes of hydrothermal regimes, vegetation shifts and diagenetic alteration of accumulated peat. Several inter-related allogenic and autogenic forcings have influenced the changes in macroelement content and stable isotope composition of peat with depth. In particular, there were climate-induced and succession-driven vegetation community shifts in domination of plants characterized by specific nutrient requirements, nutrient stoichiometry and fractionation of stable isotope values. The climate and permafrost-mediated processes like hummock uplift affected 13C uptake by Sphagnum mosses in wet and dry periods and changing hydrothermal conditions in peat profiles resulted in perturbations of the nitrogen cycle inducing N loss and enrichment 15N abundance, as well as enhanced decomposition was responsible for enrichment of organic matter in the heavier isotopes. These findings confirm the hypothesis that combined use of elemental and stable isotope composition provide meaningful insights in tracing the hydrothermal conditions and the functional state of peatbogs for paleoecological and paleoclimate reconstructions.
On a question of non-constant thermal diffusivity of soils
Authors: Glagolev M V , Dyukarev E A , Terentieva I E , Sabrekov A F 
Published: October 2022

Abstract
The general heat conductivity equation includes time- and depth-dependent soil properties (soil heat capacity and thermal conductivity). The simplified form of the heat conductivity equation contains only the soil thermal diffusivity parameter. Numerical solutions of the general and simplified equations were compared to quantify the possibility of equation reduction. Two test runs for soils with different compositions were done. The thermal regime for both peat soil and dark chestnut soil does not change significantly after using a simplified heat equation according to model estimations. The maximal soil temperature discrepancy was about 0.5 °C for peat soil and 2.2-3.3 °C for dark chestnut soil, which results in 4-6% error in methane efflux estimations.

Abstract
The bird population was monitored during ten years in the Kerzhensky Nature Reserve damaged by severe wildfires in 2010. In the burned territory 126 bird species (120 species in the breeding season) were noted, for which weighted averages of bird abundance were calculated. It was noted that the number of species was increasing gradually in the breeding season. The birds of forest edges and of dry valleys appeared already during the second post-fire year, but their abundance increased only in the third-fourth year. The bird population abundance has increased almost 2 times in the breeding season over ten years, while it has not increased significantly in the post-breeding season. The total biomass and the transformed energy, on the contrary, decreased especially in the post-breeding season. During the first six years Fringilla coelebs Linnaeus, 1758 was the absolute leader at the abundance, and its co-dominant was Anthus trivialis (Linnaeus, 1758), and in last two years Phylloscopus trochilus (Linnaeus, 1758) was the leader. The share of the leaders in the breeding season gradually decreased, and the species diversity and the alignment grew. The birds fed in the breeding season mostly on the soil surface. The share of shrubby species increased by two times a couple of years after the wildfires, and the share of crowns birds increased after another four years. The similarity of the ornithocomplex of the burnt territory in the first and last two years of the research amounted to only 0.63 units (the Sorensen-Chekanovsky index).

Abstract
The peatlands in the northern hemisphere cover just 3% of the global landmass but their impact to the carbon emission is huge. The current climate changes exert influence on these ecosystems by changing water supply, temperature regime, plant growing activity and others. Nowadays studies predicted the important role of the northern bogs and peatlands as an additional source of atmospheric CO2. In our study we estimated how microrelief and microclimatic conditions can control the CO2 emission from the bog area. We compared also the waterlogged bog conditions and forest ecosystem to find out the main drivers of soil emission dynamics during the summer season. The rate of CO2 emission varies widely within bog area depending on the microrelief of the area: hollow – 0.74±0.03, ridge – 1.69±0.08 kg CO2 m–2. The comparative analysis versus the forest area showed that the upland parts of the bog area are not inferior to the forest area in terms of the emission rate. Moisture conditions determined the CO2 efflux for the hollow site (r=0.49, p<0.05) and forested area (r=0.39, p<0.05). The temperature impact is observed for all sites and it is significant throughout the season.

Resilient modulus of crushed stone material reinforced with geogrids
Authors: Kaluder J , Lenart S , Mulabdic M , Minazek K 
Published: October 2022

AbstractUnbound base layers can be stabilized with geogrids that reduce lateral movement of granular material thus improving its stiffness through particle interlocking inside geogrid openings. Good particles-geogrid interlocking depends significantly on the ratio of geogrid aperture size to the average soil particle size. This paper describes testing of a resilient modulus and a permanent deformation of geogrid reinforced granular material. Biaxial and triaxial geogrids made with 3D printer were used in which geogrids were of different aperture sizes and rib thickness. It was thus possible to test parametrically the effect of geogrid geometry and rib stiffness on the resilient behaviour and permanent deformations. Experiments were conducted on cylindrical specimens of 160 mm diameter and 320 mm height and were reinforced with one or several layers of geogrids. The results of cyclic triaxial tests for unreinforced and reinforced specimens with created geogrids are presented in the paper, as well as the results of the previous research on commercially available geogrids. It is observed from the presented results that resilient behaviour of the tested granular material was not improved with the use of geogrids, while geogrids gave certain improvement with respect to permanent deformations. Presented research is a part of the ongoing project at the University of J.J. Strossmayer in Osijek and the Slovenian National Building and Civil Engineering Institute.

Published: October 2022

Abstract
This land reclamation project used stacked geotextile tubes to construct a 1 km long containment bund. In the past, sand is the preferred infilling material of geotextile tubes due to its ease of construction. However, due to sand scarcity in Singapore, soft soil becomes a potential alternative infilling material. One of the challenges of using soft soil as infilling material is that there will be an excessive settlement and concerns about the overall stability of the stacked tubes. Hence, the soft soil is lightly cemented before infilling into the geotextile tubes. This paper presents the design consideration and the construction sequence of the construction of a stacked geotextile tubes containment bund. Extensive instrumentation was installed at a section of the containment bund to study the behaviour of this geotextile tube. The instrumentation includes strain gauges, pore pressure transducer and total pressure cell. After two years of construction was completed, Standard Penetration Test (SPT) and laboratory triaxial test were used to evaluate the strength of the infilling material. All the instrument data and strength tests results were used to ascertain the performance of the stacked geotextile tubes containment bund.

Abstract
In France, sediments from river dredging are considered as waste. Without any special treatment, they must be stored in landfills. The dredged sediments of our area of study (North of France) are polluted with trace metals (antimony and zinc are above the French regulation threshold). The main objective of this study is to develop a new method of active depollution and dewatering treatment in order to enable the reuse of treated sediments. This treatment is carried out through ponds equipped with innovative geocomposite. This innovative geocomposite has two typical passive functions (filtration and drainage). In addition, it is functionalized by an innovative electrokinetic technology to confer it active roles (depollution and dewatering). Electrokinetic consists in applying a difference of electrical potential to a porous medium. We present here the results of a preliminary laboratory study that simulates this new method on a short-term (3 weeks) experiment. The results show that the electrokinetic treatment has an impact on the chemical and physical properties of sediments. The treatment reduces by 50% the concentration of zinc in the leachate after lixiviation.
Effects of geogrid reinforcement on the seismic performance of lightweight embankments

Published: October 2022

Abstract
Highway embankments have experienced earthquake induced damages from minor to catastrophic scales during the past few decades despite the fact that highways are considered as major lifelines that should be in continuous operation under any circumstances. Recent advances in highway engineering suggest that geosynthetic reinforcement can be considered as a novel approach to mitigate the earthquake hazards on highway embankments successfully. The use EPS geofoam inclusions is one of the prominent improvement methods available to increase the seismic performance of lightweight embankments. It’s a well-known method to reduce the magnitude of earthquake-induced dynamic forces. The aim of this numerical study is to determine the effects of using geogrid reinforcement on the seismic performance of lightweight embankments. Non-linear dynamic analyses were performed using the PLAXIS software using real earthquake records. Evaluation of the results reveal that inclusion of geogrid reinforcement layer beneath the lightweight embankment model successfully decreases earthquake-induced dynamic forces and increases the seismic performance of the embankment model in comparison of the nominally identical structure with no geogrid reinforcement. Numerical results obtained from this novel technique suggest that the implementation of a geogrid layer beneath such lightweight embankments can successfully and effectively increase the seismic performance of such structures.
Seismic design of geosynthetic-reinforced earth retaining walls following a pseudo-static approach
Authors: Gaudio D , Masini L , Rampello S 
Published: October 2022

Abstract
Geosynthetic-reinforced earth (GRE) retaining walls show a better performance than conventionally-designed walls during destructive earthquakes, due to their capability of redistributing seismic-induced deformations within the reinforced zone. In this paper, a recently-proposed method to design GRE walls is first recalled, where the wall is designed to trigger an internal plastic mechanism in the presence of strong earthquakes. Following a pseudo-static approach, the seismic coefficient k is therefore assumed equal to the internal seismic resistance of the wall k
c
int. The seismic coefficient is then calibrated against given seismic wall performance, expressed in terms of limit values of earthquake-induced displacements. Permanent displacements are evaluated through empirical relationships that were previously developed on the basis of a parametric integration of an updated Italian seismic database. Effectiveness of the proposed procedure is then demonstrated by assessing, through Finite Difference nonlinear dynamic analyses, the seismic performance of two walls, namely a GRE and a conventional gravity wall, characterised by the same seismic resistance but triggering an internal and external plastic mechanism, respectively. They are both subjected to a real strong motion, capable of activating a plastic mechanism. Results showed that lower permanent displacements are accumulated in the GRE wall where internal mechanisms are triggered.
Micro-structural analysis of cement composites using stone waste: A review
Authors: Devi K , Saini B , Aggarwal P 
Published: October 2022

Abstract
The direct disposal of industrial by-products to environment is the potential threat to the ecosystem. A possible solution can be utilization of these materials into construction industries to counteract the consumption of cement. Along with the strength and durability properties, study of micro-structural properties of concrete is equally important. The microstructure of concrete largely depends on the type of cement, admixtures, water-cement ratio and curing age. To characterize and quantify the hydration products i.e., calcium silicate hydrate, calcium hydroxide etc. of cement based materials, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) etc. techniques are being used worldwide. XRD is a powerful tool for the identification of chemical compounds present in the cement-based materials. SEM reveals the information about external morphology, chemical composition, crystalline structure and orientation of the material. EDS is an analytical technique that can be coupled with SEM and used to determine the elemental composition. A critical review of microstructural analysis using above mentioned techniques for mortar and concrete using stone waste has been done. It was found that these techniques are capable to address the morphological and crystalline structure along with chemical elements and compounds of the materials; and can also be correlated with strength and durability properties. The micrographs showed stone waste, being a filler material aid in forming the dense matrix by filling the voids. Elemental analysis coheres to the chemical compounds (calcium oxide, silica dioxide, etc.) present in the mortar and concrete specimens corresponding to micrographs images.
Reinforced Soil Structures: From Standard Design to BIM

Abstract
Building Information Modeling (BIM) emerges as a new process for the architectural, structural, engineering and construction sectors. It is based on three-dimensional (3D) parametric models which centralizes geometrical, physical and project information. The implementation of BIM within the Geotechnical Engineering sector has not reached yet a good level of robustness, frequently appearing as a new concept. BIM methodology in geotechnics and in the design of Reinforced Soil Structures (RSS) represents an opportunity which could enable the AECO world (Architecture, Engineering, Construction, Owner and Operator) to implement the infrastructural BIM, managing complex projects. With BIM, it is possible to improve the construction quality and reduce the wastage of the supplied materials as it allows an overview of the construction models through multidimensional digital design solutions which provide simulation and analysis by using different design software. This paper aims to clarify issues which might arise during the BIM design of RSS. In particular, this paper presents the case of a Mechanically Stabilized Earth (MSE) wall which comprises precast concrete facing panels and discrete high adherence polymeric soil reinforcing strips. The application of BIM technology in this research provides guidelines for design optimization and construction improvement.
