Applying eco-evolutionary optimality principles to predict leaf area index
Authors: Cai Wenjia , Prentice Iain Colin
Published: March 2022

Leaf area index (LAI), defined as one-sided green leaf area per unit ground area, is an important biophysical property of terrestrial vegetation. As the primary locus of mass and energy exchange, leaf area is directly linked with carbon assimilation, evapotranspiration, and the energy and carbon balances of terrestrial ecosystems. Predicting the response of terrestrial vegetation under climate change requires accurate characterization of plant biophysical and biochemical processes in which LAI is a key determinant. Despite many successes, global vegetation and land surface models are still subject to systematic failures and divergences between model projections, indicating a need to develop and test more reliable representations of vegetation-climate interactions. LAI in particular is not well constrained by current models. Here we apply eco-evolutionary optimality (EEO) principles to derive a parsimonious approach to the prediction of LAI by balancing net carbon gain and water loss. Plants are expected to optimally allocate carbon to foliage for light capture and CO2 acquisition, until water losses via transpiration make further canopy development unsustainable. We hypothesize that LAI is limited by the minimum of two values determined by the energy supply for photosynthesis and the water supply by precipitation, respectively. With simple equations, requiring far fewer parameters than typical complex models, we demonstrate a gridded simulated annual maximum LAI that is broadly consistent with a similar measure derived from remotely sensed observations. Further development of this model over different time scales, and its incorporation into vegetation models, would be beneficial to achieve better carbon cycle projections in a changing world.
Local time variations of auroral electrojet during storm time: DMSP and CHAMP coordinated observations
Authors: Zhong Yunfang , Xia Hao , Qian Chengyu
Published: March 2022

The auroral electrojet plays an important role in the ionosphere-magnetosphere coupling progress. Based on ten years of DMSP and CHAMP coordinated observations, we investigate the local time variations of the auroral electrojets during storm periods. The results show that the auroral electrojets respond obviously to the sudden change of solar wind inputs (merging electric field, substorm, and interplanetary shock) in all local time. The local time asymmetry of the response time and strength of the electrojets to these three types of disturbances are investigated. The auroral electrojets respond to the shock faster than the sudden change of merging electric field. The disturbed auroral electrojet strength peaks at different local times during different kinds of solar wind input events. The different features of eastward and westward electrojets during storm periods are studied during the disturbance periods. The physical mechanisms for the local time variations of auroral electrojets in response to the disturbance are discussed in detail.

Many researchers worldwide have focused on the health impact of the coronavirus disease 2019 (COVID-19) pandemic without paying much emphasis to the environmental impacts associated with the pandemic. Evidence suggests that prior to the pandemic there was an alarming increase in environmental pollution due to rising industrialization, in particular in urban areas. Following the COVID-19 pandemic, satellite data over Asia and Europe showed a substantial decrease in air pollution, in particular nitrogen dioxide. However, the increase in industrial and household wastes may pose a significant challenge to  environmental management. The improper management of these wastes poses an unforeseen “knock-on” effect on human health and the environment. It is imperative to establish an effective and safe procedure, for handling and disposing of the consequential wastes accumulating during the pandemic. The  review aims to highlight both the beneficial and detrimental effects of COVID-19 pandemic on the natural environment and  to discuss the possible strategies to improve the quality of the global environment during the period of the pandemic and beyond.

Статья посвящена вопросам экологизации производства пивоваренной продукции за счет переработки возобновляемых вторичных сырьевых ресурсов - пивной дробины, вырабатываемой пивоваренными предприятиями в больших объемах. Авторами приводится аналитический анализ степени изучения структуры и состава органических соединений пивной дробины с целью направленного извлечения нутрицевтических соединений. Отмечено, что отход пивоваренного производства является источником ценных белковых (биогенные пептиды, незаменимые аминокислоты), углеводных, фенольных (фенольные кислоты, флаваноиды, катехины, антоцианогены), липидных (насыщенных и полиненасыщенных жирных кислот, фитостеринов, токоферолов), витаминных, минеральных и пр. Отмечено, что изучается проблема увеличения доступа вследствие сложного строения углеводно-лигнинного комплекса к интересующим нутрицевтическим соединениям. Показано, что, несмотря на развивающиеся экологичные методики направленного выделения соединений, существует проблема низкого выхода или затруднений при получении целевого продукта. Намечены решения, оптимизирующие экстрагирование органических соединений за счет сверхтонкого измельчения структуры дробины, что позволяет разрушить сложно структурированную целлюлозо-лигнинную матрицу дробины.

The article is devoted to the issues of greening the production of brewing products through the processing of renewable secondary raw materials - brewer’s spent grain produced by breweries in large volumes. The authors provide an analytical analysis of the structure and composition of brewer’s spent grain organic compounds study degree with the aim of targeted nutraceutical compounds extraction. It is noted that brewer’s spent grain is a source of valuable protein (biogenic peptides, essential amino acids), carbohydrate, phenolic (phenolic acids, flavanoids, catechins, anthocyanogens), lipid (saturated and polyunsaturated fatty acids, phytosterols, tocopherols), vitamin, mineral, etc. It is noted that the problem of increasing access due to the complex structure of the carbohydrate-lignin complex to nutraceutical compounds of interest is being studied. It has been shown that, despite the environmentally friendly methods development for the targeted isolation of compounds, there is a problem of low yield or difficulties in obtaining the target product. Solutions have been outlined that optimize the extraction of organic compounds due to ultrafine grinding of the grain structure, which makes it possible to destroy the complexly structured cellulose-lignin matrix of the grain.

Существенную роль при оценке красных виноматериалов и получаемой из них продукции играет качественная характеристика цвета. Изучены показатели, оказывающие влияние на формирование цвета виноматериалов. Цель работы состояла в сравнительной оценке хроматических характеристик красных виноматериалов, предназначенных для производства игристых вин. В качестве объектов исследования в работе использовали 45 промышленных образцов красных столовых виноматериалов, соответствующих требованиям нормативной документации по физико-химическим и органолептическим показателям. Виноматериалы оценивали по контролируемым физико-химическим показателям, а также массовой концентрации фенольных веществ и по хроматическим характеристикам. Массовую концентрацию фенольных соединений в пересчете на галловую кислоту определяли спектрофотометрическим методом. Массовую концентрацию красящих веществ определяли фотоколориметрическим методом. Установлено, что для высококачественных красных виноматериалов характерны интенсивность цвета не менее 7,65 и оттенок в пределах от 0,32 до 0,51. Полученные в результате работы данные позволяют рассматривать хроматические характеристики (интенсивность цвета и его оттенок) в качестве дополнительных критериев оценки качества виноматериалов, которые предполагается использовать для производства красных игристых вин.

Published: March 2022

Use of plastics for many day to day applications has replaced traditional materials like glass or metal. Among the five most common plastics, i.e., Polyethylene Terephthalate (PET), Low-density polyethylene (LDPE), Linear low-density polyethylene (LLDPE) and High-density polyethylene
(HDPE), all forms of polyethylene are used in packaging and production of different products like shopping bags, food wrappers, water bottles etc. essentially used in day to day life. Thermoplastics unlike thermosets are used extensively as they can be recycled again with reheating process
and hence cost effective. Aggregation of this on landfill area due to its natural resistance to degradation affects soil fertility by resisting penetration of water and air into the earth. Various procedures and techniques exist to manage plastic waste, yet natural bioremediation is broadly
an acknowledged eco-accommodating strategy. In the current investigation, nineteen different fungal strains were screened with different types of polyethylene materials (powders and beads of HDPE, LDPE & LLDPE) to determine their potential of biodegradation. Degradation of polyethylene
material was determined by observing the zone of clearance and weight reduction. Results indicated ten fungal strains to be potential in degrading polyethylene which could be considered promising to be used for sustainable plastic waste management.
An Assessment of the Effectiveness of Fema's Pilot Program for Debris Removal After Hurricanes
Authors: Crowley Julia C.
Published: March 2022

Hurricane debris poses significant challenges in the post-disaster environment and can result in a variety of debris types. The Federal Emergency Management Agency (FEMA) has put forth efforts to address these challenges through the development of their Pilot Program for Debris Removal
that provides guidance and incentives for United States communities to develop FEMA-approved debris management plans. While the literature supports the need for pre-event debris management planning, there appears to be a lack of research that evaluates the effectiveness of FEMA-approved debris
management plans in the post-disaster environment. The purpose of this research is therefore to assess the effectiveness of plans developed under the guidance of FEMA's Pilot Program in preparing communities for post-hurricane debris management. Counties that received major disaster declarations
for hurricanes between 2011 and 2019 were surveyed to assess their participation in the Pilot Program. The results suggest that the Pilot Program is overall an effective means for preparing communities for post-hurricane debris management.
Migrating from Greece to Germany after 2010: a qualitative approach
Authors: Tsertekidis Georgios
Published: March 2022

Greece was severely hit by financial crisis in 2009. Outward migration flows that already existed for decades were then intensified and escalated. Those flows were, mostly, towards other European countries and also others. Among all those countries, Germany has been receiving many new Greek migrants, and is widely considered a top destination for Greek migrants. Though a qualitative approach (online interviews) and with references to existing scholarship, the study attempts to investigate five main topics concerning Greek migrants in Germany. First, the reasons that motivated, pushed or made the participants emigrate to Germany. Second, their reflections on their life in Germany. Third, whether their decision to migrate to Germany is a permanent one. Forth, what would make repatriation a possibility for them. Finally, what are their desires and plans for the future. Push and pull factors seem to be very important in the decision-making processes of the informants. Family and social networks also play major role for members of the sample in terms of deciding to migrate, choosing Germany as destination, and adjusting to their new social environment in the receiving country. The empirical evidence from the research, confirm existing theory to a great extend and raise many important parameters. Such parameters are specific economic and social factors, along with participants’ personal perceptions.
Participants in education of pupils with hearing impairment
Authors: Tureckiová Wanda
Published: March 2022

Three important subjects are always involved in the education of pupils with special educational needs – the pupil's family (and, of course, the pupil himself/herself), the school and school counselling centres. They try to ensure that the educational process is as appropriate as possible, taking into account the pupil's abilities, skills, but also the limits based on his/her type and degree of disadvantage. Pupils may be educated in special schools or in mainstream schools. Both educational pathways bring with them certain positives, but also risks.

The aim of this text will be to highlight the need for a functional relationship between all the different actors in the educational process for pupils with hearing impairment and to bring these key actors closer together in ensuring the pupil's school success, regardless of the choice of type of educational institution.
Testing and Determining the Form of Market Efficiency in Dhaka Stock Exchange (DSE)
Authors: Yasmin Farhana
Published: March 2022

This paper is focused on the idea of whether Dhaka Stock Market (DSM) is efficient in weak-form of Efficient Market Hypothesis (EMH) or not. As any country’s economic condition can be indicated by the efficiency of its stock market, so determining and measuring the different forms of efficiency has always been a well explored topic for researchers. In this paper, attempts have been made to determine and test the market efficiency and randomness of Dhaka Stock Exchange (DSE) in weak form. The entire Dhaka stock exchange has been evaluated by employing daily return from the two indices- DS30 and DSEX. Employing the normality test it is found that both the return series are not normally distributed. Moreover few parametric tests named Augmented Dickey-Fuller test (ADF), Autocorrelation Function (ACF), and Variance Ratio test (Lo & MacKinlay) have been done to examine the historic price dependencies or to examine the random walk hypothesis. The entire test results suggested that DSE is not efficient in weak form which means return from DSE does not follow a random walk.

Using Linear Flow Parameter Initial Rate Method to Optimize Completion Design of Western Canada’s Montney Tight Gas Reservoir
Authors:   Sinopec International Exploration and Production Corporation, Beijing 100029, China, Zhang Rui
Published: March 2022

Since 2007, the horizontal well staged fracturing technology has been widely used in the development of tight sandstones in the Deep Basin Montney reservoir of Western Canada Basin. The horizontal length of the horizontal well, the amount of proppant added to the fracturing and completion, the frac stage spacing, and the choice of open-hole completion or casing completion have become important factors in the optimization of completion design. LFPIR (Linear Flow Parameter Initial Rate) is observed through the double logarithmic curve of the natural gas production data of the well. After the development enters the stable linear flow stage, the linear flow corresponding to the ideal situation can be obtained when the initial production rate in this stage is inversely extended to tD≈0. The LFPIR depends on the stimulated volume of the reservoir after fracturing, and the completion effect directly affects the size of the stimulated reservoir. The completion quality of the well can be judged by studying the LFPIR of the developed Montney horizon well in the Heritage area. By comparing the LFPIR of wells with different completion designs, optimize the completion design in the tight gas reservoirs.

Published: March 2022

The search for substitutes for modern fossil fuels incentivises the use of new propulsion systems (hybrid or electric) and the use of new fuels (gaseous, mainly hydrogen). The article discusses the basic issues related to hydrogen fuel: from its extraction, through the discussion of its properties to its use and applications. Analyzes of the energy consumption involved in its extraction or production were presented, classifying hydrogen in those terms. Great emphasis was placed on design solutions for the use of hydrogen in internal combustion engines, together with discussing the concept of its combustion. The methods of storing hydrogen in a condensed and compressed form were also presented, indicating at the same time the most modern solutions available, such as mixed systems – storage in cryo-compressed form. It has been shown that the combustion of hydrogen in internal combustion engines increases their efficiency, and at the same time significantly reduces the exhaust emissions of toxic gases – including the emission of nitrogen oxides.
