Authors: Tuningsih Suci , Anggoro Subuh , Hermita Neni 
Published: November 2020

Abstract
Understanding the concept is the main basis for learning mathematics, especially at the level of primary education. Misunderstanding or misconception often occur within this level, one of them is the concept of a parallelogram. Students possess an understanding that a parallelogram, square, rectangle and rhombus are separate sets, while it is scientifically proven that square, rectangle and rhombus are special forms of parallelograms. The purpose of this study was to determine and analyze the misconception and conceptual change that occurred in fourth grade primary school students regarding the concept of parallelograms.
The study utilized mixed method explanatory sequential strategy using a three tier test format conception. The test is used to determine the initial concept, final conception and conceptual change about the concept of parallelogram geometry. The result showed that the students' initial conception of the concept of parallelograms fell into the misconception category. After puzzle based learning was implemented, most students experienced a change in concept or conceptual change from misconception to scientific conception. Puzzle based learning can be an alternative learning model to correct students' misconceptions about the concept of parallelogram shapes.

Effect of Data Length to the Consistency of Design Rainfall
Authors: Tunas I G , Oka G M 
Published: November 2020

Abstract
Design rainfall is one of the hydrology quantities that can be used for analyzing design flood. This discharge can then be applied to design and manage civil engineering structures such as drainage channels in urban areas. Generally design rainfall is analyzed using maximum daily rainfall data with a minimum data length of 10 years obtained from a rainfall observation station. In various references, the use of rainfall data with a longer range is highly recommended. This paper intends to examine the use of variations in the length of rainfall data on the consistency of design rainfall. Rainfall data from the Mutiara Meteorological Station of Palu, Central Sulawesi (1990-2019) are grouped into five categories based on the length of the data: A (10 years), B (15 years), C (20 years), D (25 years) and E (30 years). Frequency analysis was performed to predict the design rainfall of each data group using four distribution methods: Normal, Normal Log, Gumbel and Log Pearson III. Design rainfall consistency is measured based on design rainfall deviations which are calculated using the longest data. The analysis shows that the consistency of design rainfall in the study area at various return periods for all statistical distribution tends to increase in proportion to the length of the data with high category. This consistency value indicates that the 10-year rainfall data is still sufficient for frequency analysis.
Expressing Marginal Identity through Living House
Authors: Firzal Yohannes 
Published: November 2020

Abstract
As landed-sea gipsy, Akit people recognized as an ethnic group who are trying to adopt some different cultures and traditions in their daily life. In the adopting process, the people are settled down on a coastal area of an island, or at river’s estuary compound. This process has seen as a way to ensure preserving their sea life tradition and also to adopt land traditions at the same time. Through field survey and in-depth interviews method, this paper shows how most Akit people at the Rupat Island foster Chinese culture in their daily life, including on their house. The house is not only to show their marginal cultural identity but also to express the influence of the Chinese-side that can be seen both on their traditional and contemporary home. This paper confirms that the living house of Akit people has found as a form of compromising cultural life in expressing their today’s identity.

Abstract
Most people in Indonesia utilize and cultivate peatlands based on their unwise habits. They clear the peatlands by burning to be planted. If this condition is left alone, it certainly will threaten the existence and sustainability of peatland ecosystems in the future. Therefore, a breakthrough is needed to solve this problem by actively involving all interested parties. In the context of peatland maintenance specifically and environmental preservation efforts in general, the development of peat forests into peat arboretum is very important. Especially if the existence of this peat arboretum can be used as a educational facility managed by the community by applying the concept of education for sustainable development (ESD). Peatland management through the ESD-based Peat Arboretum can be a model in an effort to encourage people to be constructive and creative in facing the challenges of global warming. Moreover, this effort is also expected to create a resilient community in the sustainable management of peatlands.

Published: November 2020

Abstract
The existence of peatlands plays a very important role both locally, regionally, and globally. Besides having an ecological function to maintain biodiversity and environmental balance, it also has its economic and socio-cultural functions. Furthermore, it has provided enormous benefits for life and has had positive social and economic impacts. Peat ecosystems have been damaged due to the mismanagement of land. Areas that play specific roles in its sustainability have been converted to lands for business activities, which contradicts their characteristic function. Land cover restoration policies will be useful for improving the quality of participatory-based land cover, protecting peat domes, and conserving watersheds (DAS). An increase in greenhouse gas (GHG) emissions, which occurs due to insufficient peatland management is a serious threat to local communities and their livelihoods. Furthermore, the ecosystem can be conserved by ensuring that water is properly managed, drainage to cultivated areas is limited and peat swamp forest systems are protected. The application of eco-hydro technology can be beneficial to biodiversity as it minimizes degradation, reduces carbon emissions, and prevents fires.

Published: November 2020

AbstractExcessive and prolonged neuroinflammation leads to neuronal cell death and limits functional recovery after traumatic brain injury (TBI). Dexamethasone (DX) is a steroidal anti-inflammatory agent that is known to attenuate early expression of pro-inflammatory cytokines associated with activated microglia/macrophages. In this study, we investigated the effect of dexamethasone-conjugated hyaluronic acid (HA-DXM) incorporated in a hydrolytically degradable, photo-cross-linkable poly (ethylene) glycol-bis-(acryloyloxy acetate) (PEG-bis-AA) hydrogel on the inflammatory response, apoptosis, and functional recovery in a controlled cortical impact (CCI) rat TBI model.In vitro, DX release from PEG-bis-AA/HA-DXM hydrogel was slow in phosphate-buffered saline without enzymes, but significantly increased in the presence of hyauronidase/esterase enzymes. TBI was generated by a CCI device armed with a 3 mm tip (3.5 m s−1, depth: 2 mm) and treated immediately with PEG-bis-AA/HA-DXM hydrogel. PEG-bis-AA/HA hydrogel without DX was used for comparison and untreated TBI group was used as a control. Significant reductions in cavity size, inflammatory response, and apoptosis were observed in animals treated with PEG-bis-AA/HA-DXM compared to those receiving PEG-bis-AA/HA and untreated. Animals receiving the PEG-bis-AA/HA-DXM hydrogel also exhibited higher neuronal cell survival and improved motor functional recovery compared to the other two groups.
Indigenous knowledge on climate change adaptation: a global evidence map of academic literature
Authors: Petzold Jan , Andrews Nadine , Ford James D , Hedemann Christopher , Postigo Julio C 
Published: November 2020

Abstract
There is emerging evidence of the important role of indigenous knowledge for climate change adaptation. The necessity to consider different knowledge systems in climate change research has been established in the fifth assessment report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). However, gaps in author expertise and inconsistent assessment by the IPCC lead to a regionally heterogeneous and thematically generic coverage of the topic. We conducted a scoping review of peer-reviewed academic literature to support better integration of the existing and emerging research on indigenous knowledge in IPCC assessments. The research question underpinning this scoping review is: How is evidence of indigenous knowledge on climate change adaptation geographically and thematically distributed in the peer-reviewed academic literature? As the first systematic global evidence map of indigenous knowledge in the climate adaptation literature, the study provides an overview of the evidence of indigenous knowledge for adaptation across regions and categorises relevant concepts related to indigenous knowledge and their contexts in the climate change literature across disciplines. The results show knowledge clusters around tropical rural areas, subtropics, drylands, and adaptation through planning and practice and behavioural measures. Knowledge gaps include research in northern and central Africa, northern Asia, South America, Australia, urban areas, and adaptation through capacity building, as well as institutional and psychological adaptation. This review supports the assessment of indigenous knowledge in the IPCC AR6 and also provides a basis for follow-up research, e.g. bibliometric analysis, primary research of underrepresented regions, and review of grey literature.

Published: November 2020

Abstract
The quest for extension of holographic correspondence to non-relativistic sectors naturally includes Schrödinger backgrounds and their field theory duals. In this paper we study the holography by probing the correspondence with pulsating strings. The case we consider is pulsating strings in five-dimensional Schrödinger space times five-torus T
1,1, which has as field theory dual a dipole CFT. First we find particular pulsating string solutions and then semi-classically quantize the theory. We obtain the wave function of the problem and thoroughly study the corrections to the energy, which by duality are supposed to give anomalous dimensions of certain operators in the dipole CFT.
Methodology of large-scale research in landscape history
Authors: Nizovtsev V A 
Published: November 2020

Abstract
The purpose of this article is to present an original methodology that has been prepared for large-scale landscape-historical research. The most important methods of landscape-historical research are the systematic comparative-geographical and landscape-historical-archaeological approaches; and the main subjects of this research are not only natural territorial or natural-anthropogenic complexes, but also landscape-economic systems and landscape-historical complexes that reflect economic or spiritual human activities in specific landscape conditions during certain historical periods. A key component of landscape-historical research, complex both in subjects and in methods used, is the compilation of multiscale maps of several hierarchical levels (from regional to local) using GIS technologies, and compiling a series of multi-temporal maps for the model areas. The combination of field and desk field methods (landscape, historical, archaeological, paleogeographic, paleopedological, historical and geobotanical, various types of mapping and other natural scientific methods) with desk methods (the analysis of cartographic, collection materials) and remote-sensing methods (the analysis of aerial photographs and satellite images) allows researcher to track spontaneous and anthropogenic changes in specific landscapes, to reconstruct nature management systems and landscape living conditions of settlers, to identify the specifics of the formation of a settlement structure for the main historical chronosections, to determine the features of the interaction of man and landscape at different stages of its economic development.

Published: November 2020

Abstract
The article presents a new methodology for the internal differentiation of technogenic objects (ash and slag dumps) based on ecological and geological studies of soils, bottom sediments, surface and underground waters, based on the allocation of three zones with various permissible types of nature management in their territory. The first zone (I) is the territory directly connected with the technogenic object (the bottom of the dump); the allocation of borders of the first kind is justified by the data of the cadastral division of land and the results of route surveys. The second zone (II) is the territory of the active manifestation of the impact of the object, which has a visual manifestation (the area of wind separation, the area of accumulation of solid surface runoff, the zone of drying or inhibition of the natural stand and growth), at the initial stages of the process of natural assimilation of exposure and/or at the initial stages of regression, first of all, phytocenosis. The third zone (III) represents the territory of active natural assimilation (general dispersion and/or concentration on natural geochemical barriers) of ash and slag material products (primarily, scattering flows of heavy metals and other pollutants). An analysis of the results of this work made it possible to specify the types of environmental protection measures that are carried out depending on the identified geochemical zones, the use of which—within the framework of projects of improvement and environmental monitoring of the sanitary protection zone—will significantly reduce the costs of nature users. The rationalization of the economic and legal components is associated with a decrease in the areas for a specific type of work, and all the activities of the nature user in the controlled territory.

Authors: Kutilkin V G , Samokhvalova E V 
Published: November 2020

Abstract
Economically and environmentally sound concept of agriculture in any soil and climatic zone should be based on rational structure of acreage and cultivation of most biologically relevant crops, which are demanded in the market, produce environment-forming influence on soil fertility and state of agrocenoses. At the same time, crops shares in structure of acreage should best suit the properties of the territory, taking into account their spatial diversity. Based on this, an estimated structure of acreage for units of mesoscale complex agroclimatic zoning of the Samara region has been developed. It is based on the analysis of sowing structure in farming systems, normative and real crop yields in recent years, taking into account the recommendations of scientific institutions of the Samara region on saturation of crop rotation with grain crops, sunflower, corn and other cultures.

Geological and field control and diagnostics of treatment efficiency of a wellbore zone within carbonate reservoirs
Authors: Mukhametshin V Sh , Tyncherov K T , Rakhimov N 
Published: November 2020

Abstract
It is established that geologic parameters of deposits have a significant impact on HAT efficiency, followed by parameters reflecting the technological features of wells and deposits, and technological parameters of the treatment. The set of informative parameters that determine the most effective treatment is different in the conditions of different groups of low-productive objects of carbonate reservoirs. Field and statistical models to assess and forecast the HAT efficiency according to the parameter reflecting various indicators in complex are proposed. The models can be used to select wells for treatment and to define the approximate treatment parameters.
Production of reserves of oil- water zones of low-viscosity oil deposits
Authors: Yakupov R F , Mingulov Sh G , Mingulov I Sh 
Published: November 2020

Abstract
The authors state that during the production there is the process of transition of deposits to the category of bottom water-drive reservoirs due to frontal displacement by the injected water. As a result, the nature of water flooding becomes similar to the primary areas of bottom water-drive reservoirs. It is shown that for water-drive areas, the development is characterized by unfavorably high input values of water flooding and its intensive growth in the range of oil recovery factor from 0.1 to 0.3 fractions of units. The nature of the displacement curves of areas with water-oil zones (WOZ) is identical and differs only by the amount of water flooding of oil reserves in a deposit or area, which allows drawing a conclusion about a similar mechanism of oil displacement, which is characteristic of oil reservoir. It is shown that the main feature that characterizes the development of areas and deposits with water-oil zones is the increase in water flooding at the first stage of production.

Authors: Solovitskiy A N , Nastavko E V , Nikulin N U , Smirnov N A 
Published: November 2020

Abstract
The relevance application of shallow geophysical technologies has been established for applied research in Kuzbass. The main problem is formulated hindering its development. One of the main components of this problem is the lack of physical-geological models that provide heterogeneous information processing, allowing us to reliably determine the quantitative characteristics of the rock conditions. Traditional technologies of applied research are focused on discrete measurements (point) formed by a widely spaced grid of exploration lines, which make it difficult to build digital models of the rock conditions, which does not provide reliability and accuracy in determining their quantitative parameters. This approach is characterized by significant time and financial costs. The complexation of geophysical methods in Kuzbass in practice often depends on the availability of an instrument base. The work purpose is to study the application of shallow geophysical technologies for applied research in Kuzbass. The research object is the application of shallow geophysical technologies, and the subject is their features for applied research in Kuzbass. The research provides a generalization of practical experience in creating physical-geological models. The practical use is to improve the technology for collecting and interpreting geophysical information.

Abstract
The article is devoted to the distribution of oil and gas accumulations within the Terek-Caspian trough. Various factors that determine the spatial distribution and formation of hydrocarbon deposits in the studied region (tectonically, stratigraphically) are considered. The distribution of total oil reserves by large stratigraphic complexes is given in tabular form. Information is given on hydrocarbon deposits depending on their confinement to certain structural forms and the phase state of the fluids. The prospects of opening new accumulations of oil and gas with a further increase in geological exploration for oil and gas are determined.
