Abstract
Teenagers tend to find difficulties in filtering hoax due to a lack of literacy skills. They view that learning history through a book is boring. Instead, teenagers prefer to read information online. This study aims to improve history literacy among adolescences in order to prevent the spread out of hoax through KCBS (Kumpulan Buku Cerita Sejarah/the collection of historical narratives). The method used is qualitative with a descriptive approach. The result of this study is improved history literacy of the adolescences which enabling them to filter information gathered from blogs and websites as well as the use of Facebook as a source of information and the development of positive characters. One of many ways to improve history literacy is through literacy movement in which students are imperatively encouraged to read history books that are followed by summarizing a certain topic into the KCBS (Kumpulan Cerita Buku Sejarah). Rewriting historical narratives is hoped to improve the students’ literacy skills so that in the near future they will understand the danger of spreading out a hoax and will better respond to prevent the widespread.

Published: February 2021

Abstract
Transportation is associated with all aspects of the nation’s growth. Nowadays, sustainability is one of the primary goals of many urban transportation systems. Over the past, many innovative initiatives have been undertaken to achieve a safe, efficient, and sustainable transport system. Besides, natural environment, social wellbeing, and economic prosperity depend on sound transportation systems. In Malaysia, Penang is well-known as an industrial and medical hub. In recent years, the state has experienced rapid economic growth. However, without proper development planning for the transportation system and infrastructure, the growth for sustainable development will be jeopardised. Heavy congestions due to increasing car dependency lead to psychological stress for the travellers. There are limited studies on sustainable transportations in Penang. Therefore, this study will explore the current transportation system in Penang, including the Penang Transport Master Plan. To address the aim of the research, we adopt an inductive cross-organisational semi-structured interview to explore the current level of sustainability within Penang transportation system. From this case study, the initial findings indicate Penang is in dire need for a robust, sustainable transport system which can include rail transports and integration of different modes of transport. Moreover, the result also shows that the behaviour and attitude of Penangites towards public transportation needs to be changed. This study suggests a series of long term and short term solutions to enhance the performance of the transportation system in Penang. The balance alignment between the economic, social and environmental themes of sustainability will overcome the issues faced by the current transportation system in Penang.

Published: February 2021

Abstract
This study investigates the impacts of African wildfire aerosols (primary organic carbon, black carbon and sulfate) on the Northern Hemispheric in January. We found that wildfire aerosols emitted from equatorial Africa result in two mid-to-high latitudes atmospheric Rossby wave trains. One is from subtropical Atlantic propagating northeastward across Europe to Siberia, and the other one propagates eastward from Middle East across Asia to Pacific Northwest. The maximum positive geopotential height anomaly locates in Europe, concurrent with a greater-than-2 K land surface warming. These Rossby wave trains are excited by the atmospheric heating that caused by the wildfire aerosols in equatorial Africa and propagate into extratropics with the help of the westerly jet. Based on the diabatic heat budget analysis, the Rossby wave source is primarily from the solar absorption of black carbon of African wildfire. The present study emphasizes that wildfire aerosols, especial the absorbing aerosols, would have profound climate effects on remote regions and thus need more attentions.
On the anomalous development of the extremely intense positive Arctic Oscillation of the 2019–2020 winter
Authors: Juzbašić A , Kryjov V N , Ahn J B 
Published: February 2021

Abstract
Numerous extreme climate anomalies were recorded in the northern extratropics in January–March (JFM) 2020, significantly impacting human lives and ecosystems in the affected areas. Those anomalies were caused by an extreme positive Arctic Oscillation (AO) event, with the JFM 2020 AO index of 2.8 being the highest on the record. However, all well-established autumn precursors pointed towards the following wintertime AO phase being negative. Indeed, a negative AO phase was developing until late December when a sudden shift to the strong positive AO event occurred in the troposphere. The geopotential anomalies associated with positive AO spread into the lower stratosphere, and were steadily enhancing throughout JFM resulting in an extreme positive AO event. We show that the strong positive AO event was a result of the destructive interference of the anomalous planetary waves with climatological ones, which led to wave flattening and enhancement of the polar vortex.

Abstract
Irrigation is critical to sustain agricultural productivity in dry or semi-dry environments, and center pivots, due to their versatility and ruggedness, are the most widely used irrigation systems. To effectively use center pivot irrigation systems, producers require tools to support their decision-making on when and how much water to irrigate. However, currently producers make these decisions primarily based on experience and/or limited information of weather. Ineffective use of irrigation systems can lead to overuse of water resources, compromise crop productivity, and directly reduce producers’ economic return as well as bring negative impacts on environmental sustainability. In this paper, we surveyed existing precision irrigation research and tools from peer-reviewed literature, land-grant university extension and industry products, and U.S. patents. We focused on four challenge areas related to precision irrigation decision-support systems: (a) data availability and scalability, (b) quantification of plant water stress, (c) model uncertainties and constraints, and (d) producers’ participation and motivation. We then identified opportunities to address the above four challenge areas: (a) increase the use of high spatial-temporal-resolution satellite fusion products and inexpensive sensor networks to scale up the adoption of precision irrigation decision-support systems; (b) use mechanistic quantification of ‘plant water stress’ as triggers to improve irrigation decision, by explicitly considering the interaction between soil water supply, atmospheric water demand, and plant physiological regulation; (c) constrain the process-based and statistical/machine learning models at each individual field using data-model fusion methods for scalable solutions; and (d) develop easy-to-use tools with flexibility, and increase governments’ financial incentives and support. We conclude this review by laying out our vision for precision irrigation decision-support systems for center pivots that can achieve scalable, economical, reliable, and easy-to-use irrigation management for producers.

Published: February 2021

Abstract
Bioformulations containing microorganisms that have various useful properties for plants are widely used as an alternative to chemical pesticides. Methods for evaluating the quality of such biological products have not yet been standardized. Composition of bioformulations used for protecting plants and stimulating plant growth was studied with molecular methods. Toxicity of bioformulations was evaluated on laboratory populations of bumblebees (Bombus terrestris L.). The number of bacteria in the two bioformulations was significantly less than the manufacturer’s stated. The declared composition of microorganisms in 33% of bioformulations did not fully or partially correspond to the identified composition. Klebsiella sp. and Citrobacter sp. bacteria were found among non-target bacteria. It is known that some species of these bacteria genera are opportunistic for humans. Not one of the studied bioformulations did not cause the death of bumblebees. However, it was found that 5 bioformulations out of 18 reduced the flight activity of bumblebees, which indicates their toxic effect. The data obtained by us shows that it is necessary to develop standardized methods for assessing the quality and safety of microbiological bioformulations that are available for public sale.

Abstract
The Strategy for Improving the Quality of Food Products in the Russian Federation until 2030, approved by Government Order No. 1364-r of 29 June 2016, is aimed at ensuring full nutrition, preventing diseases, increasing the duration and quality of life of the population, stimulating the development of production and circulation of food products on the market of proper quality. One of the tasks facing the bakery industry is the need to restore the production of rye bread and varieties from a mixture of rye and wheat flour everywhere. Rye bread baking can be carried out not only in the conditions of large enterprises, but also in the conditions of low-capacity enterprises. The main task of rye selection is to improve existing varieties, that is, to create varieties with higher flour-baking qualities. The variety “Memory Bambisheva” refers to a steppe ecological group, Botanical varieties “Vulgare”. During the competitive test the average yield in the Saratov region amounted to 3.5-3.7 tons per hectare. The variety has a high winter hardiness, drought resistance to asphyxiation, morbid affection, and a good lodging resistance [1]. Studies of bakery properties of rye varieties “Saratov 7” and “Memory Bambisheva” are given, grade features of rye are noted, comparative assessment by technological indicators is carried out, technology of rye-wheat bread production is proposed. The obtained indicators show the expediency of introducing flour from white grain rye “Memory Bambisheva” into the raw material base of bakery products.

Abstract
Camelina is an oil-bearing crop that is increasingly gaining popularity in the world due to its high oil content and wide applicability. Since 2019, this crop has been cultivated in Black Sea region on an industrial scale. The study of the quality of Camelina oil showed the dependence of seed oil content on the Selyaninov’s hydrothermal coefficient (HTC). The highest oil content–44.02%–was observed in the most favorable year in terms of water availability (HTC=1.11), while the lowest–33.9%–in dry year (HTC=0.23). The comparison of fatty acid composition of Camelina oilseeds showed that the oleic acid content in varieties ranges from 14.46 to 16.57%, erucidic–from 3.07 to 3.25%, linolic–from 17.89 to 19.66%, linolenoic–from 33.02 to 37.06%. The consumer properties of Camelina oil include a relatively high total tocopherol content. In terms of its composition and properties the oil of Camelina seeds grown in Black Sea region is suitable for the synthesis of biodiesel fuel. Thus, in Black Sea region Camelina is a unique natural-biological resource that makes it possible to use oil in various areas of the national economy.

Abstract
The problem of nutrition of the world’s population has become even more acute and complex, due to the increase in the population. In solving this problem, a special role belongs to cereals and winter durum wheat in particular. The soil and climate conditions of the Crimea are quite favourable for growing this crop. The purpose of the research is to study the mutual influence of fertilizing with nitrogen fertilizers in the form of ammonium nitrate and complex organomineral fertilizers on the yield and quality of durum wheat. Field experiments were conducted in 2016-2018 in the Foothill-steppe zone of Crimea. It was found that the highest yield of winter durum wheat (52.3 C / ha) with a gluten content of 28.70% and protein of 15.56% is formed when n 60+60 is applied. The most effective complex organomineral fertilizers are Aminokat, Microkart, Atlante, foliar treatment of which contributes to the production of grain yield of 38.65-39.85 C / ha with high-quality indicators: gluten content-22.85-25.12%, protein content-12.52-13.20%.
