Published: November 2021

To achieve national target proposed by the Renewable Energy Source Directive 2009/28/EC, to also accomplish to the CO2 emission reduction targets and to decrease the energy dependency Latvian government is planning to adopt different strategy policies such as feed-in tariffs (FITs) and capital subsidies, in order to incentive investor to use renewable based technology for power production Neverthelss it is crucial to understand in long term perspective the effect and the costs of a specific policy (made even by the combination of different policy tools) applied to the energy sector. Using this model, or an extended version of it, a cost/benefit analysis of a different set of policy scenarios can be carried out. More in specific this study is driving its attention at a situation where it is possible to increase the share of wind power in the energy balance respect the use of natural gas as primary energy for power generation. Four political instruments are chosen in this model: subsidies for construction of new wind-power facilities, information package at all power supply levels for risk reduction and reduction of maintenance costs through a learning effect. The simulation period is from 2010 to 2110. The analysis of policy instruments for development of renewable energy resources in power system illustrates wide potential of system dynamic modelling use for statement of priorities on power diversification. The policy instrument of use of subsidies is a crucial priority. Feed-in tariff is not providing an evident. The reason of that can be related to the key aspect on the way Latvia is organizing its feed-in tariff policy.

A FRACTAL ACCELERATOR ON THE BASIS OF A CORRUGATED PLASMA WAVEGUIDE WITH SUPERCONDUCTING WALLS
Authors: Tkachenko I.V. , Tkachenko V.I.
Published: November 2021

The use of a two-stage mechanism for the acceleration of charged particles is proposed. The principle of acceleration is based on the use of the fractal properties of the wave spectrum of a corrugated plasma waveguide with superconducting walls. The first stage provides for the excitation of a corrugated plasma waveguide by short electron bunches in the direction of motion (the length of the bunch is significantly less than the period of the corrugation). On the second stage the test charged particles accelerates in an infinite number of harmonics of the electric field exited by an electron bunches. Calculations show that with the implementation of such an acceleration mechanism, the average speed of a non-relativistic test particle can increase several times, and its acceleration length can be up to one meter.

Four complexes of Fe(II) and Ni(II) with2-[(2 -nitrophenylimino) methyl] phenol(L1) and 2-[(4- nitrophenyliminomethyl)] phenol(L2) Schiff bases have been prepared via the microwave assisted method. The ligands and their corresponding complexes were characterized on the basis of physical properties, elemental analysis, MS, FTIR, 1H-NMR and 13C-NMR spectroscopy and electronic spectra. The FTIR spectra of the complexes showed that the ligands L1 and L2 had bidentate character coordinating through the nitrogen and oxygen atoms. On coordination, results showed that the 1H-NMR and 13C-NMR data of L1 and L2 confirmed the formation of the complexes of Fe(II) and Ni(II). The probable coordination geometries of Fe(II) and Ni(II) were octahedral. All the metal complexes were found to be non-electrolytes in ethanol. Nematicidal studies proved that the ligands and their metals showed appreciable nematicidal properties against the root knot nematode Meloidogyne arenariawith the metal complexes exhibiting higher ability than the free ligands.

Many factors predispose human beings to a disease of the lower extremities, and this condition affects approximately
eighty million Americans. Itsmanifestations may appear to be little more than a cosmetic nuisance, yet it may be an
indication of a more serious underlying problem undetected by visual inspection. Venous disease is also capable of
producing a plethora of uncomfortable symptoms, and left untreated, may progress to cutaneous pigmentation,
dermatitis, ulceration, haemorrhage, or superficial thrombophlebitis. Although uncomplicated cases of the disease
are more common, venous disease should not be taken lightly. Steps to retard disease expression and progression
should be implemented whenever possible. As blood rushes through our legs the veins send it back to the heart. In
case of prolonged standing, due to force of gravity the veins lose their ability to push the blood upwards, causing the
blood to settle down in certain areas of the veins. Varicose veins are tortuous, distended and bulging vein s
(varicosities) beneath the skin of the legs. They are most often swollen and gnarled veins that most frequently occur in
the legs, ankles and feet.
Even though the exact cause of varicose veins is unknown, there are some risk factors which contribute to
development of this problem. Some of the risk factors are, low physical activity, smoking, family heredity of varicose
veins, congenital valve or vein wall defects, valve damage from trauma, obstruction, deep vein thrombosis (DVT) or
inflammation, chronic venous distention associated with occupations requiring prolonged standing, obesity or
pregnancy, systemic conditions that interfere with venous return and loss of vein wall elasticity with ageing.

Published: November 2021

Slabs are one of the most basic components concerning the cost of the structure, because of the number of building materials utilized. It is of incentive to think about the current technologies available, meaning to make these slabs cost less or even improve its behaviour. Cobiax and post-tension slabs systems show up as an appropriate alternative. In light of this reason, this paper focuses on demonstrating the advantages and disadvantages of both Cobiax and post-tension systems. Nowadays, these systems are very popular all around the world. It is very necessary to have a wide understanding of the differences in cost and the construction duration between these two systems and have good knowledge about the advantages and disadvantages of both types. Firstly, the properties of these types of slabs have been reported and the advantages and disadvantages for both systems and then the cost and time has been compared, which are the most important factors for the owners. Finally, it has been made a comparison between the reinforcement quantities, concrete quantities, final cost and duration to finalize the construction stage.  As a result, it has been found that the post-tension system is more economical than the Cobiax system according to reinforcement quantities, on the other hand, Cobiax system is more economical in concrete quantities which leads to lighter buildings and fewer reinforcement quantities in foundations. When the construction duration has been considered, it has been found that the post-tension is the quickest system in the construction field because it is increasing the strength and durability of the structure which the Cobiax system cannot provide.
Theoretical and applied aspects of the use of agricultural and forest meliorative plantations of Ukraine for energy purposes
Authors: Roik M. V. , Fuchylo Ya. D. , Hanzhenko O. M.
Published: November 2021

Protective forest plantations are an important part of forest-agricultural landscapes and one of the most effective long-term and relatively inexpensive measures to combat wind and water soil erosion. They have a positive effect on the microclimate of the surrounding areas and can significantly increase crop yields. Also, under certain conditions, they can become an important source of bioenergy feedstock.

Goal. Development of theoretical bases and practical measures of the use of agroforestry reclamation plantations of Ukraine for energy purposes.

Methods. In the course of the research it was envisaged to develop schemes of protective forest plantations on the basis of the analysis of the existing information, long-term production and scientific experience which, at full performance of ecological functions, can be used for obtaining bioenergy feedstock.

Results. It is established that for the simultaneous use of protective forest plantations as a source of energy biomass it is necessary to include fast-growing woody plants (willow, poplar, acacia, maple, etc.) in rows or backstage, which are expected to be periodically cut for biomass. Such plants are then intensively restored by growth from stumps. The basis of such plantations for long-term and permanent performance of their protective functions should mainly consists of the rows of oak trees.

Conclusions. Protective forest plantations, in addition to the positive impact on the microclimate of the environment and a significant increase in the productivity of agricultural land, can also play an important role as a source of bioenergy feedstock. Today, forest protection plantations are losing their functions for various reasons and need to be reconstructed. At the same time, along with the restoration of protective plantations, it will be possible to obtain about 54.6 million tons of wood for energy needs and form new protective plantations, which, along with improving the ecological environment, will create a reliable feedstock base for bioenergy. The schemes presented in the article can be applied at the stage of restoration and expansion of the field protection system to increase their energy role.

Published: November 2021

Purpose. Investigate the accumulation of 137Cs and 90Sr radionuclides in the biomass of giant miscanthus depending on the agronomic methods of growing it on radioactively contaminated soils in Polissia.

Method. Biomorphological, radiometric, lysometric, statistical, comparative and computational.

Results. The article presents the results of research to study the accumulation of radionuclides 137Cs and 90Sr in the biomass of giant miscanthus. It was found that in the variants where the bioenergy crop was grown on soils contaminated with radionuclides, the accumulation of 137Cs in the biomass in the range of 14.7–18.6 Bq/kg and 90Sr — 0.46–0.54 Bq/kg was observed. The use of mineral fertilizers together with liming and inoculation with giant miscanthus with the microbial preparation Polymyxobacterin and treatment with organo-mineral fertilizer BioMAG helped to reduce the accumulation of radionuclides in the biomass of giant miscanthus as following: 90Sr — by 15% and 137Cs by 21%. It was investigated that the use of these agronomic techniques contributed to the formation of dry biomass yield at the level of 9.96 t/ha on average over three years of cultivation, which is 28% higher than the control.

Conclusion. It is established that the use of mineral fertilization in combination with liming, inoculation of rhizomes of giant miscanthus with the microbial drug Polymyxobacterin and pre-planting treatment with organo-mineral fertilizer BioMAG contributes to a significant increase in dry biomass yield with reducing 90Sr and 137Cs. The accumulation of these radioactive isotopes in the biomass of giant miscanthus when grown on radionuclide-contaminated soils did not exceed the permissible level for cereal grains, and the use of agronomic techniques helped to reduce the content of 90Sr by 9–15% and 137Cs by 12–21% compared to control. The lowest coefficients of radionuclide conversion into biomass of giant miscanthus were obtained for both 90Sr (0.15) and 137Cs (0.24) for the use of mineral fertilizers together with liming and inoculation of giant mismanthus rizomes with Polymyxobacterin and treatment with BioMAG organo-mineral fertilizer.

Evolution of turbulent kinetic energy during the entire sandstorm process
Authors: Liu Hongyou , Shi Yanxiong , Zheng Xiaojing
Published: November 2021

Abstract. An adaptive segmented stationary method for non-stationary signal is proposed to reveal the turbulent kinetic energy evolution during the entire sandstorm process observed at the Qingtu Lake Observation Array. Sandstorm which is a common natural disaster is mechanically characterized by a particle-laden two-phase flow experiencing wall turbulence, with an extremely high Reynolds number and significant turbulent kinetic energy. Turbulence energy transfer is important to the understanding of sandstorm dynamics. This study indicates that large-/very-large-scale coherent structures originally exist in the rising stage of sandstorms with a streamwise kinetic energy of 75 % rather than gradually forming. In addition to carrying a substantial portion of energy, the very-large-scale-motions are active structures with strong nonlinear energy transfer. These structures gain energy from strong nonlinear interaction. As sandstorm evolves, these large structures are gradually broken by quadratic phase coupling, with the energy fraction reducing to 40 % in the declining stage. The nonlinear process in the steady and declining stages weakens and maintains a balanced budget of energy. The systematic bispectrum results provide a new perspective for further insight of sandstorms.
Agricultural intensification vs climate change: What drives long-term changes of sediment load?

Published: November 2021

Abstract. Climate change and agricultural intensification are expected to increase soil erosion and sediment production from arable land in many regions. However, so far, most studies have been based on short-term monitoring and/or modeling, making it difficult to assess their reliability in terms of long-term changes. We present the results from a unique data set consisting of measurements of sediment loads from a 60ha catchment (the HOAL Petzenkirchen in Austria) over a time window spanning 72 years. Specifically, we compare Period I (1946–1954) and Period II (2002–2017) by fitting sediment rating curves for the growth and dormant seasons for each of the periods. The results suggest a significant increase in sediment yield from Period I to Period II with an average of 11.6 ± 10.8 ton·yr−1 to 63.6 ± 84.0 ton·yr−1. The sediment flux changed mainly due to a shift of the sediment rating curves (SRC), given that the annual streamflow varied little between the periods (5.6 l·s−1 and 7.6 l·s−1, respectively, on average). The slopes of the log regression lines of the SRC for the growing season and the dormant season of Period I were 16.72 and 4.9, respectively, whilst they were 5.38 and 1.17 for Period II, respectively. Climate change, considered in terms of rainfall erosivity, was not responsible for this shift, given that erosivity decreased by 30.4 % from the dormant season of Period I to that of Period II, and no significant difference was found between the growing seasons of Periods I and II. However, the sediment flux changes can be explained by changes in crop type and parcel structure. During low and median streamflow conditions (i.e. Q < Q20 %), land consolidation in Period II (i.e. theparcel effect) did not exert an apparent influence on sediment production. Whilst with increasing stream flow (Q > Q20 %), parcel structure played an increasingly role in sediment yield contribution, and leading to a dominant role due to enhanced sediment connectivity in the landscape at extremely high flow conditions (i.e. Q > Q2 %). The increase in cropland in Period II at the expense of grassland had an unfavourable effect on sediment flux, independent of streamflow, with declining relevance as flow increased. We conclude that both land cover change and land consolidation should be accounted for simultaneously when assessing sediment flux changes. Especially during extremely high flow conditions, land consolidation substantially alters sediment fluxes, which is most relevant for long-term sediment loads and land degradation. Increased attention to improving parcel structure is therefore needed in climate adaptation and agricultural catchment management.

Previous studies of snack names have focused on their psychological impact on consumers in different cultures but have tended to ignore their onomastic features. This study helps to address this gap based on a corpus of 121 snack names extracted from the book Chinese Famous Local Delicious Food and Special Products. This study explores the patterns of syllables, sounds, and name types of snack names compiled in this small-scale corpus. In this investigation, it was found that descriptive names were the dominant type in the corpus and the most frequently described type feature was the food ingredient. Interestingly, metaphorical names in the corpus were in general found to be related to shape similarities. Contrary to previous findings on dish names and drinking brand names in China, the snack names examined in this corpus showed a preference for three-syllable patterns and “light” or “flat” tones. After discussing these and other findings of this research, this paper discusses what insights this study may provide for other name investigations that utilize corpus linguistic approaches.
