Authors: Orekhovskaya A A 
Published: March 2022

Abstract
The article considered the issues of increasing the yield of winter wheat grain, depending on the method of basic tillage, application of manure and mineral fertilizers. A correlation and regression analysis of the yield of winter wheat grain from the applied agrotechnical techniques, indicators of the fertility of typical chernozem were carried out. It was found that the greatest increase in yield in the grain-grass crop rotation was due to shaft-free tillage for maximum fertilization, and in the grain-tillage with the same doses of fertilizers - with the use of minimal tillage. Linear regression equations have been calculated to predict the yield of winter wheat grain from agrotechnical techniques.

Published: March 2022

Abstract
The efficiency of milking dairy farm animals depends on the reliability of the milking equipment. Domestic milking machines are equipped with UVU 45/60 with a rotary vacuum pump that has an extremely limited service life, which is mainly due to imperfection of the lubrication system for its working bodies. In addition, oil loss along with the exhaust air leads to high lubricant consumption and environmental pollution. Analysis of modern designs of foreign rotary vacuum pumps shows that their operational reliability and service life are increased at the expense of maximum reduction of friction in the working body due to the improvement of the lubrication system, increased productivity, and elimination of oil loss and environmental pollution. One of the technical solutions to solve these problems is to equip the vacuum installation with a device that provides circulating lubrication of the pump working bodies without emitting oil into the atmosphere. The team of authors substantiated the design of the oil trap for the pump lubrication system with the efficiency of separating oil from the exhaust air up to 95 %. Experimental vacuum installations with single-circuit and double-circuit lubrication systems have been developed. Production tests of vacuum installations performed at a number of farms in Stavropol Territory confirmed high efficiency of the proposed engineering solution. The operational reliability of the pump due to the circulating lubrication of its working bodies in terms of the prolonged overhaul period increased by 65-70 %. Irrecoverable oil losses and environmental pollution are almost excluded. The payback period for additional capital investments in the vacuum installation design does not exceed 1.2-1.5 years.
Using growth regulators in production of peas

Published: March 2022

Abstract
Intensive agriculture poses new challenges for science and practice that go far beyond increasing the gross yield. They include the prevention of lodging of cereals when high agricultural background, the synchronization of fruit ripening, which is necessary for their machine harvesting, an increase in the proportion of early harvesting with its unchanged value. The competent use of plant growth regulators will allow solving such problems. In most cases, they are not used to increase the yield of dry matter per unit area. This task is successfully solved by such traditional means as fertilizers. Physiologically active compounds are widely used in vegetable and berry crops, in crops of grain and legumes. These crops, due to their biological characteristics, require management of growth and development during the period of crop formation, especially in conditions of the Non-Black Earth Zone. All common pea varieties are characterized by uneven ripening, cracking of beans, being close to the soil and significant lodging of stems. All these things force researchers to search for physiologically active compounds that can shorten the stem, activate photosynthetic activity, accelerate maturation, facilitate harvesting and increase productivity. Undoubtedly, as the understanding of the mechanisms of hormonal regulation of plant growth and development is expanded and deepened, more and more possibilities will appear for managing these processes to increase productivity or reduce labor costs.

Published: March 2022

Abstract
Electric vehicle, as one of the low carbon footprints, has transformed a wide range of energy and public sectors. Utilizing the WHO Covid-19 pandemic statement, we search for the optimal portfolio from the top seven Electric Vehicle (EV) enterprises in ASEAN. Using the MonteCarlo simulation of optimal risky assets portfolio, we find that before and during the pandemic, the optimal portfolio weights differ significantly. Before (during) the pandemic, the investment weight of optimal portfolio consists of Toyota Motor Corporation 49.83% (42.99%), Star 8 Corporation 23.20% (9.73%), Hyundai Motor Corporation 20.81% (10.63%), BMW.DE 2.79% (32.08%), Honda Motor Company 2.56% (0.64%), Mitsubishi Motor Corporation 0.68% (0.09%), and Nissan Motor Co. 0.14% (3.84%). The Sharpe Ratio shows how during the pandemic, the portfolio of EV stocks give more excessive return compare to their risks, from 93.55% to 250.62%. These findings support the notion of how EV stocks are investible, especially during the Covid-19 pandemic.

Published: March 2022

Abstract
Indonesia’s bioenergy potential is enormous. Utilization of bioenergy can be a solution to future energy independence. It is predicted that fossil fuel production will start to decline in 2025 and the need for other sustainable sources of energy will be significantly increase. To turn the potential to real benefits, the supporting conditions policies, and regulations to ensure incentives, prices, and subsidies, need to be made jointly by various related structures of the government. The development of bioenergy in Indonesia shall be planned in the context of sustainability. That shall include plans for the growth of green environment, mitigation, and adaptation to changes in climate. It will be expected to give a big contribution to the Bonn Challenge, which is an attempt globally to return the 350 million hectares of green land status in 2030, as intended by The United Nations Framework Convention on Climate Change for the reduction of greenhouse gases emissions.
Modelling low carbon electricity generation of an integrated ASEAN power grid
Authors: Atmo Gigih Udi , Otsuki Takashi , Nurcahyanto Eri 
Published: March 2022

Abstract
In 1997, 10 economies of the Association of Southeast Asian Nations (ASEAN) established the ASEAN Power Grid (APG), a cross-border interconnection network that effectively uses regional energy resources. This study aims to quantify the effect of ASEAN power grid interconnection on electricity exports-imports between south-east Asia economies and its implications for renewable energy shares and carbon emission in power generation. Three scenarios are assessed in this model. The Base Scenario simulates APG parameters in 2030, considering four existing interconnections and those interconnection projects currently under construction. The second scenario, HAPUA Scenario, includes all the future interconnection projects outlined in the HAPUA report. The carbon tax scenario as the last scenario, aims to evaluate whether carbon pricing policies in Southeast Asia may incentivise cleaner energy and renewable energy development in the region. Under the HAPUA Scenario, Indonesia increases coal and/or gas-fired generation for electricity exports, contributing to a slight increase in CO2 emissions from power generation for the ASEAN region. It appears that carbon price affects the choice of electricity generation and incentivise cross-border electricity trade. Under the carbon tax scenario, emissions will decline to 719 MtCO2 or 22% lower than the base scenario and 24% than the HAPUA scenario.

Abstract
There are significant studies that have quantified oil palm water footprint as an indicator of environmental sustainability but an estimation of water footprint under varying soil types furthermore is still limited. The objectives of the study were to estimate whether annual variations of soil type and yields significantly effects for the oil palm water footprint. The data from three types of soil (spodosol, inceptisol, ultisol) were collected from an oil palm plantation in Pundu village, Central Kalimantan, Indonesia. To perform the water footprint analysis we utilize water balance accounting equations via application Cropwat 8.0. From that, we determine the crop irrigation scheduling to compute the blue, green, and grey water footprint of oil palm fresh fruit bunch in the area. Our analysis found that the actual evapotranspiration of spodosol and inceptisol have the same value: 1242 mm/year whilst ultisol is 1239 mm/year. The total water footprint of oil palm varied considerably with the largest value being 1310.04 m3/ton for ultisol. The actual evapotranspiration of spodosol and inceptisol have the same value of 1242 mm/year whilst ultisol is 1239 mm/year. The higher production resulted in a lower water footprint and vice versa. Moreover, the total water footprint from ultisol soil type has the highest value due to the lowest yields. The difference in evapotranspiration value resulted in the insignificant value of total water footprint. The lower water availability, the lower water use, and the higher actual irrigation requirement in oil palm plantation yet showed the unnotable impact on water footprint in different soil types for the oil palm plantation.

Montmorillonite-based heterogeneous catalysts for efficient organic reactions
Authors: Takabatake Moe , Motokura Ken 
Published: March 2022

Abstract
In this review, we give a brief overview of recently developed montmorillonite-based heterogeneous catalysts used for efficient organic reactions. Cation-exchanged montmorillonite catalysts, metal catalysts supported on montmorillonite, and an interlayer design used for selective catalysis are introduced and discussed. In traditional syntheses, homogeneous acids and metal salts were used as catalysts, but the difficulty in separation of catalysts from products was a bottleneck when considering industrialization. The use of solid heterogeneous catalysts is one of the major solutions to overcome this problem. Montmorillonite can be used as a heterogeneous catalyst and/or catalyst support. This clay material exhibits strong acidity and a stabilizing effect on active species, such as metal nanoparticles, due to its unique layered structure. These advantages have led to the development of montmorillonite-based heterogeneous catalysts. Acidic montmorillonite, such as proton-exchanged montmorillonite, exhibits a high catalytic activity for the activation of electrophiles, such as alcohols, alkenes, and even alkanes. The montmorillonite interlayer/surface also functions as a good support for various metal species used for oxidation and carbon-carbon bond forming reactions. The use of an interlayer structure enables selective reactions and the stabilization of catalytically active species.
Low-loss high-impedance circuit for quantum transduction between optical and microwave photons
Authors: Tsuchimoto Yuta , Kroner Martin 
Published: March 2022

Abstract
Quantum transducers between microwave and optical photons are essential for long-distance quantum networks based on superconducting qubits. An optically active self-assembled quantum dot molecule (QDM) is an attractive platform for the implementation of a quantum transducer because an exciton in a QDM can be efficiently coupled to both optical and microwave fields at the single-photon level. Recently, the transduction between microwave and optical photons has been demonstrated with a QDM integrated with a superconducting resonator. In this paper, we present a design of a QD-high impedance resonator device with a low microwave loss and an expected large single-microwave photon coupling strength of 100s of MHz. We integrate self-assembled QDs onto a high-impedance superconducting resonator using a transfer printing technique and demonstrate a low-microwave loss rate of 1.8 MHz and gate tunability of the QDs. The corresponding microwave photon decay time of 88 ns is longer than the time necessary for the optical-microwave transduction process as well as the transmon-resonator swap operation time. This feature will facilitate efficient quantum transduction between an optical and microwave qubit.

Abstract

Objectives
To investigate the gene mutational profile of urachal carcinoma in correlation with its clinicopathologic features.

Methods
We analyzed genetic mutations in 30 cases of urachal carcinoma by next-generation sequencing (NGS) test. Histologic slides and clinical data were reviewed.

Results
The patients included 21 men and 9 women, with a mean age of 53 years (range, 24-75 years). The urachal carcinomas included mucinous (11), enteric (10), signet ring cell (8), and high-grade neuroendocrine (1) subtypes. Targeted NGS analysis demonstrated genetic mutations in all the urachal tumors (mean, 2; range, 1-4). TP53 was the most mutated gene (25), followed by KRAS (9) and GNAS (8) genes. TP53 mutations were more common in the signet ring cell subtype (7/8), and GNAS mutations were present only in the mucinous (5/11) and signet ring cell subtypes (3/8) but not in the enteric subtype (0/10). KRAS mutations were significantly associated with cancer stage IV (P = .02) and younger patient age (P = .046). Furthermore, the presence of KRAS mutations in urachal carcinoma portended a poorer overall survival (P = .006).

Conclusions
Urachal carcinoma demonstrates frequent gene mutations that are associated with distinct clinicopathologic features. Gene mutation may underlie the development and progression of this aggressive disease.

Authors: Andreatta Massimo , Berenstein Ariel J , Carmona Santiago J 
Published: March 2022

AbstractSummaryA common bioinformatics task in single-cell data analysis is to purify a cell type or cell population of interest from heterogeneous datasets. Here, we present scGate, an algorithm that automatizes marker-based purification of specific cell populations, without requiring training data or reference gene expression profiles. scGate purifies a cell population of interest using a set of markers organized in a hierarchical structure, akin to gating strategies employed in flow cytometry. scGate outperforms state-of-the-art single-cell classifiers and it can be applied to multiple modalities of single-cell data (e.g. RNA-seq, ATAC-seq, CITE-seq). scGate is implemented as an R package and integrated with the Seurat framework, providing an intuitive tool to isolate cell populations of interest from heterogeneous single-cell datasets.Availability and implementationscGate is available as an R package at https://github.com/carmonalab/scGate (https://doi.org/10.5281/zenodo.6202614). Several reproducible workflows describing the main functions and usage of the package on different single-cell modalities, as well as the code to reproduce the benchmark, can be found at https://github.com/carmonalab/scGate.demo (https://doi.org/10.5281/zenodo.6202585) and https://github.com/carmonalab/scGate.benchmark.
