We analysed the quantity and quality of Quercus robur L. acorns after years with a very poor yield under the canopy of natural oak stands of various compositions, ages and stock densities in the northeastern part of Ukraine. We determined the mass of 1,000 healthy and damaged acorns of the current year. The levels of variability were estimated for the number and mass of acorns under the canopy of the studied stands. The dependences of the number of acorns on the age of oak stands and their stock density were studied. The total number of acorns under the canopy of natural oak stands was 9,900–19,000 seeds per hectare with a total mass of 26.8–54.1 kg per hectare in 2020 and 8,600–17,200 seeds per hectare with a total mass of 22.7–48.4 kg per hectare in 2021. The proportion of damaged acorns was about 70% both in 2020 and 2021. The largest number of acorns was concentrated under healthy trees (without signs of decline) that had a well-developed crown and, therefore, received more sunlight and heat. The identified quantitative and qualitative estimates and acorn spreading pattern need to be considered when selecting sites for further natural seed regeneration in old-aged oak stands.
Assessment of the soil-protecting services of the forest ecosystem: a case study in Ilam catchment, Iran
Authors: Mahdavi Ali , Motaharfard Elham
Published: November 2023

The natural forests of western Iran play a key role in delivering services and goods to local society. Nonetheless, this forest ecosystem, despite its importance, is threatened by natural factors and anthropogenic activities, resulting in decreasing soil quality and soil erosion. The present research aimed to assess the effects of the forest ecosystems on soil erosion control in Ilam catchment in southwest Iran. For this purpose, after estimating the soil loss in natural conditions (NC), we predicted the amount of soil erosion under two scenarios: (i) convert natural forest with 20% canopy cover to destructed forest with 0% canopy cover (SC.1), (ii) increase forest cover by 40% (SC.2). Our results indicate that the estimated mean soil erosion was within the range of 9.36 t ha-1 yr-1 in irrigated and garden use to about 256 t ha-1 yr-1 in bare soils under NC. We found that when converting natural forest to destructed forest, the mean annual soil erosion rate increased 105.75 t ha-1 yr-1, 118.1 t ha-1 yr-1, and 19.57 t ha-1 yr-1 in the dense forest, sparse forest, and Agri-Forest use, respectively. These results show the protective effect of the forest against soil erosion.

In Djebel Fellaoucene, mattorals and their regressive and progressive dynamics are affected by several factors, namely climate, geography, human activities, overgrazing and fires. This research aims to investigate whether these factors have an impact on the structural dynamics of the area’s forest soils and show a correlation between the soils’ chemical and microbial properties and these factors. In this regard, we have analysed chemical properties: organic matter, pH, conductivity, calcium carbonate (CaCO3), moisture and carbon as well as microbial properties: basal respiration, microbial biomass and metabolic quotient (qCO2), all from 80 soil samples collected from degraded mattorals on different altitudes and exposures. Principal Component Analysis (PCA) which has been made revealed that soil dynamics and correlations between chemical and microbial properties depend on the aforementioned factors; an increase in moisture, organic matter, carbon and conductivity as well as a decrease in the mass and bacterial respiration in the North-exposed sites under anthropogenic pressure and overgrazing by sheep and goats. Whereas opposite results were found in the South-exposed sites degraded by fires and undergrazing by cattle. Anthropogenic pressure and overgrazing in sites which have recently been burned lead to a decrease in microbial properties despite an increase in organic matter and moisture content. Qualifying and quantifying the impact of these degradation factors on forest soils allows us to establish effective restoration, conservation strategies and defend rangelands in arid areas.

Authors: Mercuri Emílio Graciliano Ferreira , Tamm Toomas , Noe Steffen Manfred
Published: November 2023

The carbon and water fluxes and their inter-relations are key aspects of ecosystem dynamics. In this study, regionalization was used in transferring parameters from the GR4J-Cemaneige model calibrated in Reola hydrographic basin to predict daily flows in Kalli basin; both watersheds are located in the southeast of Estonia. Evapotranspiration data was collected from the MODIS sensor of the Terra satellite and from the Station for Measuring Ecosystem-Atmosphere Relations (SMEAR Estonia). Precipitation data was collected from Tartu–Tõravere and SMEAR Estonia stations and river flow from Reola hydrometric station. The year 2011 was used for model warm-up, model calibration was done in 2012–2017 and the 2018–2020 period was used for validation. The GR4J-Cemaneige model was calibrated at Reola Basin, with a Nash-Sutcliffe Efficiency index of 0.73. The 6 constants of Reola subbasin were transferred to Kalli subbasin for river flow simulation. Net ecosystem exchange (NEE) was measured at the 70 m SMEAR tower with the eddy covariance technique. The balances indicate that the ecosystem at Kalli watershed is slowly becoming a source of carbon and less water is available at the catchment reservoir. NEE has increased from -1.23 μmol m-2 s-1 in 2015 to -0.62 μmol m-2 s-1 in 2020, while the delta water storage decreased from 0.24 mm in 2015 to -0.05 mm in 2020. This behavior may increase soil drying and oxidation, and it will probably release more carbon in the future. This research allows a better understanding of the Järvselja hemi-boreal forest water-carbon dynamics.

Authors: Pırtı Atınç , Hoşbaş Ramazan Gürsel , Yücel Mehmet Ali
Published: November 2023

Jamming is electromagnetic radiation or reflection that impairs the function of electronic instruments and equipment or communication tools. Intentionally disrupting or interfering with GPS signals, which are used for positioning, navigation, and timing, known as “GPS jamming”, is accomplished using a radio frequency emitting device. On January 8, 2022 (the day of a NATO exercise), it was investigated how GPS signal jamming affected the position accuracy at three IGS points in Iceland. The obtained coordinate differences between kinematic processing and static processing reached values of about 0.5–10 meters for the MAYV, and HOFN stations in this study. In addition to GPS signal jamming effect in Iceland, horizontal and vertical velocity fields of the three IGS stations in Iceland covering a twenty-two year period (2000–2022) in this study. According to the obtained results, a motion of about 2cm–2.5cm per year (horizontal) and 0.1cm–2.1cm per year (vertical) was computed at the three IGS stations (HOFN, REYK, and MAYV) located in Iceland.
Avoiding PV-Induced Overvoltage through Grid-Connected Batteries Using Model Predictive Control
Authors: Kirchsteiger Harald , Landl Sarah
Published: November 2023

The problem of temporary overvoltage when integrating large renewable power plants into the existing grid is considered. A grid-connected battery energy storage system with an advanced predictive control algorithm is proposed to reduce the overvoltage in time periods of excessive renewable production. An approximative grid model is developed using system identification methods on regular operation data. A model predictive control algorithm utilizing predictions of load and generation determines the optimal operation strategy of the battery. A comparison in simulation between a reference case with PID control and the proposed algorithm shows a large reduction of the time spent in overvoltage conditions, especially in the case of consecutive days of high renewables production. The results suggest that energy storages combined with a predictive control strategy can effectively alleviate the overvoltage problem in renewables integration. Especially in the case when available storage capacity is comparatively low, a uniform overvoltage reduction can be realized. The method can potentially increase the PV host capacity of current grids.

A palma forrageira (Opuntia e Nopalea) responde positivamente aos tratos culturais como capina e roço das plantas daninhas. No entanto, a mão de obra escassa e o custo elevado da mão de obra é um desafio que os produtores, comunidade científica e governo tem que solucionar. O objetivo do trabalho foi avaliar 9 (nove) herbicidas comerciais e algumas misturas deles no controle de plantas daninhas na cultura da palma forrageira variedades Miúda (N. cochenillifera) e Orelha de Elefante Mexicana (O. stricta) no município de Caruaru, Pernambuco, Brasil. Foram realizados dois experimentos na Estação Experimental do Instituto Agronômico de Pernambuco (IPA) em Caruaru-PE. Os delineamentos utilizados foram em blocos ao acaso com três repetições. Os tratamentos avaliados foram: 1. Ausência de controle de plantas daninhas, 2. Capina manual, 3. Roçagem, 4. DMA®806BR (2,4-D), 5. GLIFOSATO ATAR 48® (glifosato)+DIURON NORTOX 500 SC® (diurom), 6. GLIFOSATO ATAR 48® (glifosato)+AMERIS® (tebutiurom), 7. HEXAZINONA-D NORTOX (hexazinona+diurom), 8. VOLCANE® (MSMA), 9. GOAL®BR (oxifluorfem), 10. TARGA®50 BR (quizalofope-p-etílico), 11. FUSILADE® 250 EW (fluasifope-p-butílico), 12. AMERIS® (tebutiurom), 13. GLIFOSATO ATAR 48® (glifosato)+DIURON NORTOX 500 SC® (diurom)+AMERIS® (tebutiurom). A composição botânica das plantas invasoras, solo descoberto, sobrevivência, toxicidade e produtividade de matéria fresca e seca da palma foram avaliadas nos dois anos de cultivo. Dentre as espécies identificadas as que tiveram as maiores densidades foram: Ageratum conyzoides, Nicandra physalodes, Scoparia dulcis, Conyza bonariensis, Amaranthus viridis, Acanthospermum hispidum, Alternanthera tenella, Senegalia tenuifolia, Cordia goeldiana, Senegalia tenuifolia, Turnera subulata e Poaceae. Os herbicidas GLIFOSATO ATAR 48®+AMERIS®; AMERIS®; e GLIFOSATO ATAR 48®+DIURON NORTOX 500 SC®+AMERIS® foram os mais eficientes no controle das plantas daninhas, devido a altas percentagens de solo descoberto (75 a 99,67%), baixa toxicidade (<8,33%) e elevada produtividade de matéria fresca (120,69 a 167,05 t.ha-1) e seca (21,75 a 24,40 t.ha-1). A produtividade de matéria seca e fresca foi correlacionada positivamente entre si, e entre o solo descoberto e a sobrevivência das plantas.

Circles of hell or circles of support? (Using the «person-in-environment» concept in social work practice)
Authors: Semigina Tetyana , Stoliaryk Olha
Published: November 2023

Modern trends in the development of client-centered approaches in social work, which rely on the client’s internal resources and his strengths, although they consider a person as an expert in his own life situation and one who is able to cope with life challenges, emphasize the influence of the environment in which the client is.
This paper is based on the theoretical analysis of the "person-in-environment" concept and reflection of the experience of using tools based on this concept in the authors’ structured interventions focused on the clients' strengths development.
The analysis of the academic literature confirmed that the “person-in-environment", developed in the 1980s, remains a popular concept of eco-system social work. It suggests considering the client's experience and life situation through the lenses of dependence on the external environment. An individual's environment affects how a person evaluates the surrounding reality and the processes occuring in their life, way of thinking, and behavior patterns in response to difficulties. From the viewpoint of this concept, the social work objective is to understand the needs and problems of clients through the study of environmental influences, finding and assessing the resourcefulness of social systems that affect the clients’ well-being, and working to strengthen them.
The "person-in-nvironment" concept is used to obtain a holistic view of the impact of the environment on clients, it can be applied  as a basis for practical interventions, focused on the use of strengths, which allows you to resist social pressure, to defend own interests and needs, and will strengthen faith in own ability. The experience of piloting of techniques based on the "person-in-environment" concept gives reason to say that they help clients to understand their dependence on environmental systems, to identify a "toxic environment", to realize the possibility of control over their own lives, to strengthen faith in their own strength and ability to make decisions about desired relationships in a person's life.
Generalized myoclonus restricted to the “Smack” withdrawal state: A rare case report
Authors: Gera Ayushi , Garg Shobit , Mittal Shaily
Published: November 2023

Myoclonus is regarded as a direct neurotoxic effect of opioid metabolites. It is seen less frequently in conjunction with opioid discontinuation (opioid withdrawal myoclonus [OWM]). Only a few case reports from palliative medicine and anesthesia have highlighted the development of OWM. We report an unusual case of a 35 years old, opioid-dependent (smack) adult male who developed abnormal involuntary jerky movements of limbs and torso in the withdrawal phase. There was no change in the level of consciousness. The neurological examination as well as serum biochemistry was normal. The electroencephalogram showed no epileptiform activity. The patient was started on oral substitution therapy (tramadol 150 mg/day) after which abnormal movements subsided within 72 h. We conclude that myoclonus can be a part of opioid withdrawal. Appropriate recognition of its benign nature and psycho-education to patients and families shall foresee better outcomes.
Enhancement of glucose recovery from banana stem by 4-cycle enzymatic hydrolysis

Published: November 2023

Valorisation of banana waste into value-added products has gained an increasing interest since decades ago. To date, there is still limited information on the rational direction of banana stems, which are conventionally dumped and burnt at the field or disposed into water streams, leading to serious environmental pollution. In this work, we present a novel approach to maximise the recovery of glucose from banana stem. Initially, the effect of substrate load (1%, 3%, 5%, 7% and 9%) on the enzymatic hydrolysis by liquozyme and spirizyme was investigated. Following that, 4-cycle enzymatic hydrolysis was performed and the recovery of glucose was determined for every cycle. The results showed that the optimum substrate concentration for the enzymatic hydrolysis of the banana stem was 1% (w/v) which gave the best hydrolysis yield. Evaluation of one to five cycles of enzymatic hydrolysis showed that the highest hydrolysis yield and rate were achieved during the fourth cycle, which was 2.3-fold and 4.4-fold compared to that achieved in the first cycle. Moreover, the glucose concentration recovered in the fourth cycle was 2.4-fold higher than that attained in the first cycle. Our results clearly showed the advantages of conducting multiple cycles of enzymatic hydrolysis of banana stems. In summary, this work presents a novel approach for maximising the glucose recovery from the banana stem where the method may also be applicable for recovering sugar from other agricultural wastes.

Published: November 2023

A detailed chemical understanding of \ce{H2} interactions with binding sites in the nanoporous crystalline structure of metal--organic frameworks (MOFs) can lay a sound basis for the design of new sorbent materials. Computational quantum chemical calculations can aid in this quest. To set the stage, we review general thermodynamic considerations that control the usable storage capacity of a sorbent. We then discuss cluster modeling of \ce{H2} ligation at MOF binding sites using state-of-the-art density functional theory (DFT) calculations, and how the binding can be understood using energy decomposition analysis (EDA). Employing these tools, we illustrate the connections between the character of the MOF binding site and the associated adsorption thermodynamics using four experimentally characterized MOFs, highlighting the role of open metal sites (OMSs) in accessing binding strengths relevant to room temperature storage. The sorbents are MOF-5, with no open metal sites, \ce{Ni2}(\textit{m}-dobdc), containing Lewis acidic Ni(II) sites, Cu(I)-MFU-4\textit{l}, containing $\pi$ basic Cu(I) sites and V\textsubscript{2}Cl\textsubscript{2.8}(btdd), also containing $\pi$-basic V(II) sites. We next explore the potential for binding multiple \ce{H2} molecules at a single metal site, with thermodynamics useful for storage at ambient temperature; a materials design goal which has not yet been experimentally demonstrated. Computations on Ca$^{2+}$ or Mg$^{2+}$ bound to catecholate or Ca$^{2+}$ bound to porphyrin show the potential for binding up to 4 \ce{H2}; there is precedent for the inclusion of both catecholate and porphyrin motifs in MOFs. Turning to transition metals, we discuss the prediction that two \ce{H2} molecules can bind at V(II)-MFU-4\textit{l}, a material that has been synthesized with solvent coordinated to the V(II) site. Additional calculations demonstrate binding three equivalents of hydrogen per OMS in Sc(I) or Ti(I)-exchanged MFU-4\textit{l}. Overall, the results suggest promising prospects for experimentally realizing higher capacity hydrogen storage MOFs, if nontrivial synthetic and desolvation challenges can be overcome. Coupled with the unbounded chemical diversity of MOFs, there is ample scope for additional exploration and discovery.
Signal Amplification and Near-Infrared Translation of Enzymatic Reactions by Nanosensors

Published: November 2023

Enzymatic reactions are used to detect analytes in a range of biochemical methods such as enzyme-linked immunosorbent assays (ELISAs). To measure the presence of an analyte, they are conjugated to a recognition unit and convert a substrate into a (colored) product that is detectable by visible (VIS) light. Thus, the lowest enzymatic turnover that can be detected sets a limit on sensitivity. Here, we report that substrates and products of horseradish peroxidase (HRP) and β-galactosidase change the near-infrared (NIR, 800-2400 nm) fluorescence of (bio)polymer modified single-walled carbon nanotubes (SWCNTs). Therefore, SWCNTs translate a VIS signal into a beneficial NIR signal. Moreover, the affinity of the nanosensors cause a higher effective local concentration of the reactants for the optical measurement. This leads to a non-linear sensor-based signal amplification and translation (SENSAT). We find signal enhancement up to ≈ 120x for the HRP substrate p-phenylenediamine (PPD), which means that reactions below the limit of detection in the VIS can be followed in the NIR (≈ 1000 nm). The approach is also applicable to other substrates such as 3,3’-5,5’-tetramethylbenzidine (TMB) and direct observation of the HRP reaction. An adsorption-based theoretical model fits the observed signals and corroborates the sensor-based enhancement mechanism. This approach amplifies signals, translates them into the NIR and increases sensitivity of biochemical assays.

Biomolecular simulations have become an essential tool in contemporary drug discovery and molecular mechanics force fields constitute its cornerstone. Developing a high quality and broad coverage general force field is a significant undertaking that requires substantial expert knowledge and computing resources, which is beyond the scope of general practitioners. Existing force fields originate from only a limited number of groups and organizations, and they either suffer from limited numbers of training sets, lower than desired quality because of oversimplified representations, or are costly for the molecular modeling community to access. To address these issues, in this work, we developed an AMBER-consistent small molecule force field with extensive chemical space coverage and we provide Open Access parameters for the entire modeling community. To validate our force field, we carried out benchmarks of quantum mechanics/molecular mechanics conformer comparison and free energy perturbation calculations on several benchmark data sets. Our force field achieves a higher level performance at reproducing quantum mechanics energies and geometries than two popular open-source force fields, OpenFF2 and GAFF2. In relative binding free energy calculations for 31 protein-ligand data sets, comprising 1079 pairs of ligands, the new force field achieves an overall root mean square error of 1.19 kcal/mol for ∆∆G and 0.92 kcal/mol for ∆G on a subset of 463 ligands without bespoke fitting to the data sets. The results are on par with the leading commercial series of OPLS force fields.

Published: November 2023

In biology, membranes are the key structures to separate and spatially organize cellular reaction systems. Their rich dynamics and transformations during the cell cycle are orchestrated by specific membrane-targeted molecular machineries many of which operate through energy dissipation. Likewise, man-made molecular rotary motors powered by light have previously shown drastic effects on cellular systems, but their physical roles on and within lipid membranes remain largely unexplored. Here we systematically investigate the impact of rotary molecular motors on well-defined biological membrane systems, focusing on supported lipid bilayers (SLBs) and giant unilamellar vesicles (GUVs). Notably, we observe dramatic mechanical transformations of these systems upon motor irradiation, indicative of motor-induced membrane expansion. We systematically explore the influence of several factors on this phenomenon, such as motor concentration and membrane composition, and find that in particular, membrane fluidity plays a crucial role in motor-induced deformations. At the same time, only minor contributions from local heating and singlet oxygen generation are observed. Most remarkably, we find that membrane area expansion under the influence of the motors continues as long as irradiation is maintained, and the system stays out-of-equilibrium. Overall, this research contributes to a comprehensive understanding of how molecular motors interact with biological membranes, elucidating the multifaceted factors that govern membrane responses and shape transitions in the presence of these remarkable molecular machines, thereby supporting their future applications in chemical biology.

Research and Application of Excitation Method Optimization in Areas with Low Signal-to-Noise Ratio of Seismic Data
Authors: Yang Dawei
Published: November 2023

In areas with a low signal-to-noise ratio of seismic data, the continuity of the seismic reflection waves in the exploration target layer is very poor, which will reduce the imaging accuracy and make it impossible to solve certain geological tasks. This article suggests an approach to address the issue of seismic acquisition by optimizing excitation parameters. It involves conducting a detailed investigation of the surface structure, enhancing the observation system, increasing the coverage appropriately, and transitioning from combined-well excitation to single-well excitation. Additionally, the use of technical tools like qualitative evaluation of the observation system and forward modeling are employed to determine the final optimized seismic acquisition plan. The effectiveness of this approach is evident from the seismic profile obtained in an exploration area in Inner Mongolia.

Authors:   Financial University, Moscow, Russia, Tikhonova A.V.
Published: November 2023

The problem of finding the most effective instruments of state support within the framework of the implementation of national projects is relevant and largely justified by the lack of an adequate approach to assessing the effectiveness of each individual instrument (tax, budget, credit incentives in their complex application. The subject of the study is the separation of the effects of state financial support of economic entities. The purpose of the work is to develop a methodological approach to assessing the separate effects of state support of economic entities based on the analysis of modern theoretical views and applied practice. The article analyzes modern methods of assessing the effects and effectiveness of state financial support used by the executive authorities of the Russian Federation: comprehensive assessment of indicators, agile methodology, point-rating assessment, integral indicator. The advantages and features of the agile methodology of the Federal Tax Service of Russia, which allows assessing the effectiveness of tax benefits in relation to specific taxpayers, are considered. As a result of their analysis, two sections of the assessment were identified: general and separate separately. The features and possibilities of using multidimensional tools for separating the effects of various instruments of state financial support are characterized. The approbation of tools for separating the effects of instruments of state financial support for industrial production was carried out on the example of a combinational two-factor grouping. Conclusions are drawn about the effectiveness of joint and separate application of budgetary, credit and tax instruments to support industrial production within the framework of the national project "Labor Productivity". The novelty of the research lies in the development of a methodological approach that allows separating the effects of the use of tax, budgetary and credit instruments of state financial support and based on the use of combinational statistical grouping.
