Ecological monitoring is essential for the timely detection of pests and diseases in crops and vegetation. It enables the implementation of appropriate measures to prevent the spread of harmful organisms and minimize the damage they cause. Mathematical modeling of the behavior of pests and insects, such as locusts, provides valuable insights into their flight patterns, propagation, and harmfulness. The development of mathematical models and computational algorithms allows researchers to simulate and predict the behavior of locusts and other harmful organisms, enabling the implementation of effective control measures. In addition to monitoring and controlling pests, ecological monitoring also provides valuable data on environmental trends, including climate change, air and water quality, and soil conditions. Such information is critical for developing strategies for sustainable resource management, including agriculture, forestry, and conservation. Overall, ecological monitoring and the development of mathematical models and computational algorithms play a crucial role in protecting the environment and ensuring the sustainable use of natural resources. These tools enable researchers and policymakers to make informed decisions about resource management and implement effective measures to mitigate the impact of harmful organisms and environmental degradation.

Published: November 2023

Maize is a global leader among grain crops in terms of planting area. Its uniqueness is related to a high potential yield and versatility. There are a great number of pest species that significantly damage maize plants reducing the yield by 30-50 % sometimes and drastically decreasing grain quality. One of the most dangerous pests in Russia and overseas is the corn borer. The paper presents the research data on five insecticides with the following active ingredients (a.i.): emamectin benzoate (50 g/l), aversectin C (50 g/l), thiacloprid (100 g/l) + deltamethrin (10 g/l), imidacloprid (700 g/l) + alpha-cypermethrin (120 g/l), and lambda-cyhalothrin (50 g/l) + chlorantraniliprole (100 g/l). Maize plants differed in the degree of damage to cobs and stalks depending on the product employed.Our research goal was to study the effectiveness of insecticides against the Asian corn borer (Ostrinia furnacalis Guenee). The research showed that the insecticides containing imidacloprid (700 g/l) + alpha-cypermethrin (120 g/l) and lambda-cyhalothrin (50 g/l) + chlorantraniliprole (100 g/l) were the most effective against the Asian corn borer. No damage to maize ears, peduncles, and stalks was detected if these insecticides were applied. A high percentage of damaged ears and stalks was observed in the control variant (without pesticide application).

Authors: Markova L.M. , Ovchinnikov S.M.
Published: November 2023

The article discusses the results of soil-geochemical studies carried out on the territory of the Chelyabinsk urban district. The features of the profile distribution of pollutants within the landscape catena are established. The maximum concentrations of heavy metals are confined to the upper soil horizons of the eluvial position under forest vegetation. The soils of the superaquatic position under moist meadow and swamp vegetation are less polluted. The most polluted soil layer is located at a depth of 4-10 cm from the surface. This may be due to a decrease in heterogeneous emissions from the city’s metallurgical enterprises over the past 30 years.

Published: November 2023

In this study, the fungus strain LS-4.2 isolated from the bottom sediments of Lake Lower Suzdalskoe was tested for its algicidal activity. We identified the strain LS-4.2 as Penicillium canescens summing its morphological characteristics with the reported DNA sequence. We revealed that the filtrate of a 7-day culture of the fungus suppressed the cell growth of toxic Microcystis aeruginosa. Our results showed that the filtrate caused rapid M. aeruginosa growth inhibition up to complete cell lysis recorded after 4 days. Living fungal mycelia did not suppress the growth of cyanobacterium. According to the results of this study we suppose that strain LS-4.2 may be a potential bioagent in the control of cyanobacterial blooms.

Published: November 2023

The article studies the ecological state of two neighboring lakes Sredniy and Nizhniy Pert on the Bolshoy Solovetsky Island after their separation by a dead earthen dam during the construction of the lake-channel system. The studies were carried out in July 2021. It was revealed that these anthropogenic changes led to a change in the regime of lakes, especially Nizhniy Perth, which lost its flow. Samples of water and bottom sediments were taken from the deep waters of these reservoirs. In these samples, the main hydrochemical parameters were determined, and bottom sediments were studied for the content of moisture, iron and sulfur, organic carbon and nitrogen in them. A difference was noted in the water color of the studied lakes, which is due to anthropogenic influence and the isolation of water bodies, and in their mineralization, which is associated with the location of water bodies relative to the White Sea. A greater amount of organic matter (carbon) was found in the water and bottom sediments of the lake. Sredniy Perth, therefore, in the bottom layer of the water column of this reservoir, a lower oxygen content was noted compared to the neighboring lake, while in none of them did anaerobic conditions arise in the water. The C/N ratio in the sediments indicated a greater contribution of the allochthonous pathway of organic matter inflow into both lakes, and this was slightly more pronounced in the less flowing lake Nizhniy Perth. A difference in the granulometric composition of the sediments of the studied reservoirs was revealed, which is associated with a change in hydrochemical regimes and different sedimentation conditions as a result.

The purpose of the study is to substantiate the directions for improving state support for the strategic development of the agricultural sector. The information and analytical resources of the study were the spatial database compiled by the authors in the context of the subjects of the Russian Federation by indicators on average for 2017-2019. The influence of price factors on the formation of physical and economic accessibility of products has been studied. It was revealed that in the process of formation the price interests of sellers and buyers have different polarity. In order to create a balanced formation of physical and economic accessibility of products, it is necessary to increase prices to create conditions for expanded reproduction of producers’ resources, on the one hand, and reduce prices to increase the purchasing power of the population in food products, on the other hand. Moreover, the influence of natural and economic factors simultaneously on the conditions of reproduction and purchasing power is observed. It is proposed to supplement the provisions on the classification of state support for the agricultural sector with measures to subsidize the sphere of production and the sphere of consumption of products, the level of which is advisable to differentiate on a territorial basis.

Published: November 2023

Carrying out full lifecycle management of SF6 gas recovery, purification, and recycling, developing new digital control technologies, and eliminating SF6 gas emissions from the source are of great significance for achieving the “dual carbon” goal. Given the low level of digital control of SF6 gas at present, especially in the situation, the SF6 gas recovery rate, the effective volume of the gas chamber, and gas weight cannot be accurately measured at an on-site inspection surface, this paper carries out research on SF6 gas recovery rate measurement at on-site inspection surface and key technologies of gas measurement. An intelligent online monitoring device such as SF6 gas recovery rate and effective chamber volume of high voltage electrical equipment was developed, which can quickly identify SF6 gas density, recovery rate, effective chamber volume, weight, and other parameters in high voltage electrical equipment, and evaluate the detection methods such as gas recovery rate and effective chamber volume. The results show that when the recovery rate was about 96.5%, the maximum positive deviation between the recovery rate measured by the detection device and that measured by the weighing method was 0.32% and the maximum negative deviation was -0.24%, both of which are less than 0.50%. When the container to be tested was 1000 L, the maximum indication error was -1.51%, which can meet the requirements of digital control in the SF6 gas recycling and reuse process of high-voltage electrical equipment.

Authors: Zhang Lu
Published: November 2023

Peatland fires are frequent, but the effect of fire on soil organic carbon in peatlands is still currently variable. Especially at long time scales, it has not been clarified. In order to reveal the relationship between carbon accumulation patterns in peatlands at long time scales in response to local fire changes, high-resolution peat sediments from peatlands in the Three River Plain were selected and analysed for stratified charcoal debris and organic carbon in this paper. The results showed that the stronger carbon sequestration capacity in the periods of 0.6, 0.75, 1.25, 2.3, 2.75, 2.9, 3.6 and 5 ka BP corresponded to weaker fire intensity or even no fire. Late-Holocene fires in the Sanjiang Plain reduced the rate of carbon sequestration, suggesting that fires have been an important driver of the reduction in carbon sequestration capacity over the last 6000 years.

Published: November 2023

The utilization of mountain wind resources are important issues in the development of wind energy. However, when wind flows over mountainous terrain, its velocity and direction undergo certain changes, resulting in more complex mountain wind fields and induced structural wind effects. To study the distribution characteristics of horizontal wind in mountainous areas, in this study, wind tunnel experiments were conducted on regular mountain models with different slopes to investigate the wind field characteristics at various locations in the mountain range. The research shows that near the mountain surface, the wind speed and velocity ratio follow the order of mountain top > mountain waist > mountain foot, with a wind acceleration effect at the mountain top (wind speed ratio greater than 1) and a wind deceleration effect at the mountain foot and waist (wind speed ratio less than 1). As the height increases, the wind speed ratios gradually approach 1. Moreover, with an increase in slope ratio, the wind speed decreases at the mountain foot and increases at the mountain top. And with the increase of the slope leads to an increasing difference in wind speed ratio between the mountain top and the foot.

Authors: Zhang Junxue , Han Jiankang , Zhai Xiaoting
Published: November 2023

The data shows that the greatest electricity consumption occurs during the first three months of the year, accounting for approximately 31.4% of the total electricity consumption. This is attributed to the high energy consumption associated with heating air conditioners during cold weather conditions. Similarly, the corresponding carbon dioxide emissions follow a similar pattern, with a peak observed in the first quarter of every year. Therefore, it is important to focus on reducing carbon emissions during this period. These findings highlight the need for energy-efficient heating and cooling systems that can help reduce the negative impact on the environment while promoting sustainability. By adopting renewable energy sources and improving energy efficiency in building systems, we can work towards creating more sustainable and environmentally friendly built environments.

Published: November 2023

Sugarcane is one of the largest economic crops in China. However, the current domestic sugarcane straw crushing and returning machines have limitations such as short service life, poor crushing effect, and low operating efficiency. In order to solve these problems, a 1GYF-240 sugarcane straw crushing and returning machine was developed in this study. First of all, the power is provided by the tractor, and at the same time, it drives the blade in the crushing mechanism to rotate at a high speed. Next, the profiling leaf collector collects the sugarcane stalks that are close to the ground and feeds them into the crushing chamber. Finally, the swinging knife and the fixed knife are used for crushing, and the crushed straw is evenly thrown to the field along the rear baffle under the action of centrifugal force, thereby completing the operation of crushing and returning the sugarcane straw to the field. The results of field experiments show that the qualified rate of sugarcane straw crushing is 93.8%, and the work efficiency is 0.78hm2·h-1, which shows good operation effect. The results of comparative experiments show that this study not only solves the environmental pollution problem of traditional incineration well, but also has the function of heat preservation and water retention. In addition, compared with similar domestic models, the experimental results show that the crushing and returning machine has obvious advantages in picking up rate and crushing rate of sugarcane straw, and has higher reliability in actual operation. This research can provide the foundation and support for the design and popularization of the sugarcane leaf crushing and returning machine.

Recently, biodiesel has become more attractive owing to its attractive properties such as positive environmental effects, non-toxic, biodegradable, derived from renewable resources. Hence, this paper aims to provide an overview on biodiesel production and generations of biodiesel produced from distinct feedstocks. Thereafter the comparison of fuel properties, oil yield for different edible and non-edible oil and feedstock cost in distinct countries is given. Finally, the properties of biodiesel developed from distinct feedstock are summarized. The outcome demonstrates that the various sources offered varying yields owing to the process factors. However, the yield of biodiesel varies w.r.t. feedstocks owing to the physical and chemical characteristics of the sources and the process factors. Among waste cooking oil, commercial diesel fuel, and biodiesel from waste cooking oil, waste cooking oil offered higher pour point (284K), density (0.924 kg/L), water content (0.42%), kinematic viscosity (36.4 mm2/s) than commercial diesel fuel and biodiesel from waste cooking oil.

Published: November 2023

In recent years, with the vigorous development of e-commerce, China's express delivery industry has experienced a peak of development. However, the production of express garbage during this process has led to serious environmental pollution problems. The relevant national policies have also set higher requirements for the reduction, standardization, and recycling of express boxes. Therefore, it is urgent to reduce the size of the express box. It has been observed that many express delivery companies have joined the "green revolution" of promoting express delivery boxes. However, due to factors such as cost and safety, the utilization rate of circular express delivery boxes has not improved. Based on the current situation analysis, this study will address the existing problems and challenges of the current circulating box in practical applications. It will consider designing a green, shared, and circulating express box that can be implemented with existing technology. Therefore, this study is based on RFID technology to conduct innovative research and development, design a circular shared express box named Re-gas, and establish a closed-loop system for the supply chain of express boxes. This will promote the green and efficient transformation of the express industry. However, because the designed and manufactured express box samples have not been tested, and due to limitations imposed by application scenarios, cost control, and industry barriers, the project may have some defects and challenges.

Renewable energy Portfolio Standard (RPS) policy plays a significant role in reducing carbon dioxide emissions and promoting the development of renewable energy. Based on bounded rationality, this paper constructed an evolutionary game model to analyze energy power production decision-making, involving both fossil and renewable power producers as participants. Through the discussion of evolutionary game equilibrium, the study revealed the following findings: (1) marketised TGC price benefits the reduction of fossil energy power production: (2) Tire implementation of RPS policy does not necessarily lead to an increase in total renewable energy production; (3) Under RPS policy, the higher proportion of renewable energy quota is not always advantageous for reducing fossil energy power production.

With the process of urbanization and the ‘the Belt and Road’ initiative, the cross-border energy demand in southwest China has grown rapidly, driving the development of the energy system. The accuracy of load forecasting directly affects the application of energy systems, so it is crucial to conduct research on load forecasting for energy terminals in border and cross-border areas. However, there is a seasonal shift in the diverse energy consumption loads in border and cross-border regions, and currently, research on load forecasting and simulation of typical low-carbon energy consumption scenarios under this feature is basically in a blank state. Based on existing problems, this article conducts research on load modeling methods under the significant ‘seasonal migration’ characteristics of border and cross-border loads, conducts research on characteristic industries in border and cross-border areas, establishes typical low-carbon energy consumption scenarios and simulation models in border and cross-border areas, and uses sensitivity analysis method of dynamic simulation to analyze the impact of different influencing factors on the load of various building types, The Monte Carlo simulation prediction method is used to obtain the sensitivity probability distribution of various influencing characteristic factors, and the typical energy consumption building load model is modified. Finally, by comparing the energy consumption simulation results with statistical results, the accuracy of simulation energy consumption prediction is verified to be higher than 90%.

A large number of distributed power sources are injected to the distribution network, which can cause island operation in planned or unplanned situations. The islanded operation caused by the fault will cause the inverter to go off the grid in serious fault conditions such as short circuit between phases and disconnection. After the island is formed, if the common connection point before the island exchanges more power, a sudden change in the voltage within the island occurs. The frequency and phase angle changes of the voltage in the island are closely related to the characteristics of the inverter phase-locked loop, and the frequency mutation generally does not cause sudden changes in frequency due to a certain inertia of the phase-locked loop. Due to sudden changes in load power angle, input fault ride-through, etc., sudden changes in the phase angle of voltage in islands may occur. In order to solve the possible problems of power quality deterioration in islands, passive, active, and remote islanding detection schemes can be adopted, and the three schemes have their own advantages and disadvantages. In actual operation, it is necessary to consider the cooperation relationship between island detection, protection, safe automatic control and fault ride through.

Osteoarthritis is a common chronic degenerative disease, of which the essence is
the degenerative changes of bone and joint cartilage, involving damage in
multiple structures such as bone, synovium and joints. In the mechanism of
arthritis inflammation is closely related, and therefore the exploration to
inhibit inflammatory mediators is crucial for the clinical prevention and
treatment of osteoarthritis. Inotodiol is a lanostane triterpenoid isolated from
Inonotus obliquus, which had been extensively reported to be an
anti-inflammatory agent, but its effect on arthritis remains unknown. In this
study, we firstly demonstrated that inotodiol significantly reduced
IL-1β-induced chondrocyte injury and inhibited the release of
inflammatory factors. At the same time, experiments in vivo showed that
inotodiol could effectively improve the symptoms of joint injury in mice and
reduce the area of cartilage destruction, indicating that inotodiol may be a
potential therapeutic drug for osteoarthritis.

Im Dezember 2022 hat die Weltgesundheitsorganisation (WHO) die Empfehlungen für die Behandlung der medikamentenresistenten Tuberkulose (TB) aktualisiert. Die Bewertung dieser Empfehlungen und der neuen Studiendaten macht auch für den deutschsprachigen Raum eine Aktualisierung der Leitlinienempfehlungen zur Therapie der mindestens Rifampicin-resistenten Tuberkulose notwendig, welche die entsprechenden Kapitel ersetzt. Auch für Deutschland, Österreich und die Schweiz wird nun eine verkürzte, mindestens 6-monatige MDR-TB-Therapie unter Einsatz der festgelegten und nicht veränderbaren Medikamentenkombination Bedaquilin, Pretomanid, Linezolid und Moxifloxacin (BPaLM) empfohlen, wenn alle hierfür notwendigen Voraussetzungen erfüllt sind. Diese Empfehlung gilt für TB-Fälle mit nachgewiesener Rifampicin-Resistenz einschließlich der Rifampicin-Monoresistenz. Zur Behandlung der präextensiven (prä-XDR) TB wird weiterhin in erster Linie eine individualisierte, an die Resistenzdaten angepasste Therapie über 18 Monate empfohlen. Die nicht veränderbare Medikamentenkombination Bedaquilin, Pretomanid und Linezolid (BPaL) kann bei prä-XDR alternativ angewendet werden, wenn alle Voraussetzungen dafür erfüllt sind. Die notwendigen Voraussetzungen für den Einsatz von BPaLM und BPaL werden in diesem Amendment zur S2k-Leitlinie „Tuberkulose im Erwachsenenalter“ begründet dargestellt.

Chronic knee pain is a common condition. Causes of knee pain include trauma, inflammation, and degeneration, but in many patients the pathophysiology remains unknown. Recent developments in advanced magnetic resonance imaging (MRI) techniques and molecular imaging facilitate more in-depth research focused on the pathophysiology of chronic musculoskeletal pain and more specifically inflammation. The forthcoming new insights can help develop better targeted treatment, and some imaging techniques may even serve as imaging biomarkers for predicting and assessing treatment response in the future. This review highlights the latest developments in perfusion MRI, diffusion MRI, and molecular imaging with positron emission tomography/MRI and their application in the painful knee. The primary focus is synovial inflammation, also known as synovitis. Bone perfusion and bone metabolism are also addressed.
Diffusion Tensor Imaging of Peripheral Nerves: Current Status and New Developments
Authors: Yoon Daehyun , Lutz Amelie M.
Published: November 2023

Diffusion tensor imaging (DTI) is an emerging technique for peripheral nerve imaging that can provide information about the microstructural organization and connectivity of these nerves and complement the information gained from anatomical magnetic resonance imaging (MRI) sequences. With DTI it is possible to reconstruct nerve pathways and visualize the three-dimensional trajectory of nerve fibers, as in nerve tractography. More importantly, DTI allows for quantitative evaluation of peripheral nerves by the calculation of several important parameters that offer insight into the functional status of a nerve. Thus DTI has a high potential to add value to the work-up of peripheral nerve pathologies, although it is more technically demanding. Peripheral nerves pose specific challenges to DTI due to their small diameter and DTI's spatial resolution, contrast, location, and inherent field inhomogeneities when imaging certain anatomical locations. Numerous efforts are underway to resolve these technical challenges and thus enable wider acceptance of DTI in peripheral nerve MRI.
