Dependency length minimization and its limits: a possible role for a probabilistic version of the Final-Over-Final Condition (to appear in Language)
Authors: Jing Yingqi , Blasi Damián Ezequiel , Bickel Balthasar
Published: September 2021

A prominent principle in explaining a range of word order regularities is dependency locality, i.e. a principle that minimizes the linear distances (dependency lengths) between the head and its dependents. However, it remains unclear to what extent language users in fact observe locality when producing sentences under diverse conditions of cross-categorical harmony (such as the placement of verbal and nominal heads on the same vs different sides of their dependents), dependency direction (head-final vs head-initial) and parallel vs. hierarchical dependency structures (e.g. multiple adjectives dependent on the same head vs nested genitive dependents). Using 45 dependency-annotated corpora of diverse languages, we find that after controlling for harmony and conditioning on dependency types, dependency length minimization (DLM) is inversely correlated with the overall presence of head-final dependencies. This anti-DLM effect in sentences with more head-final dependencies is specifically associated with an accumulation of dependents in parallel structures and with disharmonic orders in hierarchical structures. We propose a detailed interpretation of these results and tentatively suggest a role for a probabilistic principle that favors embedding head-initial (e.g. VO) structures inside equally head-initial and thereby length-minimizing structures (e.g. relative clauses after the head noun) while head-final (OV) structures have a less pronounced preference for harmony and DLM. This is in line with earlier findings in research on the Greenbergian word order universals and with a probabilistic version of what has been suggested as the Final-Over-Final Condition more recently.

The evolutionary functions of imagination and fiction and how they may contribute to psychological wellbeing during a pandemic
Authors: van Mulukom Valerie , Clasen Mathias
Published: September 2021

The COVID-19 pandemic caused widespread social disruption and lockdowns, with negative consequences for psychological wellbeing worldwide. We argue that imaginative-narrative simulation - the mental simulation of events, sourced from memory and fiction, brought together through narrative - may have had substantial positive contributions to psychological wellbeing during restrictions of the pandemic. In particular, we propose that this simulation is a tool to support (i) planning and future thought, (ii) coping and emotion regulation, (iii) bonding and social needs, and (iv) identity and worldviews. We suggest that these functions can contribute to coping during the pandemic restrictions, though we also address potential maladaptive effects of the functions on psychological wellbeing, such as rumination. We put forward our framework, include relevant research on the evolutionary functions of simulation through imagination and fiction, and review relevant studies of the effects of imagination and fiction on psychological wellbeing during the COVID-19 pandemic. In light of previous research and the negative psychological effects of COVID-19 disruptions and lockdowns, we suggest that there is much scope for future directions on this topic.
The value of confidence: Confidence prediction errors drive value-based learning in the absence of external feedback

Published: September 2021

Reinforcement learning algorithms have a long-standing success story in explaining the dynamics of instrumental conditioning in humans and other species. While normative reinforcement learning models are critically dependent on external feedback, recent findings in the field of perceptual learning point to a crucial role of internally-generated reinforcement signals based on subjective confidence, when external feedback is not available. Here, we investigated the existence of such confidence-based learning signals in a key domain of reinforcement-based learning: instrumental conditioning. We conducted a value-based decision making experiment which included phases with and without external feedback and in which participants reported their confidence in addition to choices. Behaviorally, we found signatures of self-reinforcement in phases without feedback, reflected in an increase of subjective confidence and choice consistency. To clarify the mechanistic role of confidence in value-based learning, we compared a family of confidence-based learning models with more standard models predicting either no change in value estimates or a devaluation over time when no external reward is provided. We found that confidence-based models indeed outperformed these reference models, whereby the learning signal of the winning model was based on the prediction error between current confidence and a stimulus-unspecific average of previous confidence levels. Interestingly, individuals with more volatile reward-based value updates in the presence of feedback also showed more volatile confidence-based value updates when feedback was not available. Together, our results provide evidence that confidence-based learning signals affect instrumentally learned subjective values in the absence of external feedback.
EFFICIENCY OF THE NOZZLES OF CONTACT HEAT EXCHANGERS
Authors: Klimov R. , Kirilyuk V.
Published: September 2021

At powerful thermal power plants or boiler houses, the efficiency depends to the greatest extent on the amount of heat lost with the cooling of turbine condensers, exhaust gases that have a high temperature. Each type of such losses is a large unused energy potential, that is, a secondary energy resource that can be used. At the same time, the use of secondary resources and industrial emissions will improve the ecological situation in the regions, and this has always been an urgent task.

As a rule, large losses of thermal secondary energy resources in boilers are reduced by installing economizers and air heaters. Contact types of heat exchangers are distinguished by the best efficiency in operation. In contact economizers, to increase the surface of heat and mass transfer, it is advisable to use various types of nozzles.

The aim of the study is to develop such an indicator, with which it is possible to determine the optimal type of nozzle of the contact economizer installed after the steam boiler. This indicator should show the highest heat engineering efficiency of the packing with a small hydraulic resistance of the heat exchanger.

By using the coefficient of specific energy efficiency of the packing in the heat exchanger of waste gases of heating equipment, it is possible to analyze the work of the packing space from the standpoint of thermal and hydraulic efficiency and select the optimal type of packing for each individual unit or installation. Geometric parameters determine the required volume of the apparatus and the hydraulic resistance of the exhaust gases movement. The hydraulic resistance affects the consumption of electrical energy for the drive of smoke exhausters for sucking off exhaust gases from heat engineering installations through the free section of the heat exchanger. Taking into account the developed indicator of the specific energy efficiency in waste heat utilizers, it is possible to select such a type of packing, at which the optimal level of waste heat utilization will be achieved.
RESEARCH SENSITIVITY OF THE ROTOR FLUX LINKAGE OBSERVER TO CHANGE PARAMETERS OF THE ASYNCHRONOUS MACHINE
Authors: Klyuyev O. , Sadovoi O. , Sokhina Y.
Published: September 2021

When changing the parameters of the control object to ensure the required quality of control, the tuning parameters of the control system must be changed. Investigation of the sensitivity of mathematical models helps to choose the right technical parameters of the regulators. Therefore, there is an urgent scientific task, which consists in the development of mathematical models for calculating the steady-state values ​​of the sensitivity functions of the coordinates of non-linear systems to changes in their parameters.

When synthesizing observers of the rotor flux linkage, it is indicated that the signal for evaluating the rotor flux linkage is most sensitive to a change in the active resistance of the rotor of an induction machine. However, the numerical values ​​of the transmission coefficients between the coordinates of the observer and the increments of the parameters of the asynchronous machine during its operation are not given, which does not allow a comparative analysis of the degree of influence of changes in certain parameters of the asynchronous machine on the signals of the observer of the flux linkage.

The task is to find and compare the numerical values ​​of the functions of the sensitivity of the coordinates of the observer of the rotor flux linkage to the change in the parameters of the asynchronous machine by joint analytical solution of the static equations of the observer's sensitivity model and the state model of the asynchronous machine.

In this work, analytical expressions are obtained for the steady-state values ​​of the sensitivity functions of the coordinates of such a nonlinear object as an observer of the rotor flux linkage to a change in the parameters of an asynchronous machine. A comparative analysis of the values ​​of the transmission coefficients between the parameters and coordinates in the system asynchronous machine — observer of the rotor flux linkage for its various rotation speeds is carried out. The proposed technique makes it possible to find the numerical values ​​of the transmission coefficients and to compare the degree of influence of various parameters of the asynchronous machine on the coordinates of the flux linkage observer. Transient processes obtained in the course of solving the equations of the dynamics of an asynchronous electric drive with an observer of flux linkage complement the results of analytical calculations. The performed calculations are aimed at increasing the depth of analysis of the properties of the flux link observer, which helps to reasonably choose the structure of feedbacks when synthesizing a closed observer.
Incarcerated Workers’ Self-Organizing Contributes to Abolition Movements against Global Apartheid
Authors: Vance Chris
Published: September 2021

Incarcerated workers across Canadian prisons have organized and conducted strike actions. These actions, however, have been rejected by the Canadian state, on the basis that the incarcerated workers are not legally employees. The court ruling ( Guérin et al. v. Canada 2018), while accepting evidence of the prisoners’ material hardships from their low pay and from reprisals for striking, excluded them from the legal protections of employees and thus devalued the prisoners’ labour. The self-organizing efforts reveal the levels of inequality experienced by incarcerated workers in the ruling order of global apartheid, “in which race and mobility feature as primary variables for which heightened security and militarization are the answer” ( Besteman 2020 , 1). This article discusses the effects of prisoners’ organizing in the larger context of social justice. In so doing it examines cultural texts that document interactions between organizers inside and outside prisons and their contribution toward alternatives to carceral cultures. This article argues that the cultural production by prisoners and their supporters express the conditions in which prisoner self-organizing is necessary for larger social transformation. The creation and nurturing of collective relationships with one another, both within and across prison walls, clarify common grounds for liberation struggles, and connect envisioned freedoms to overthrow the various forces that enclose communities and hold significant numbers of us captive.
Process and Becoming: Spatiality and Carceral Identities
Authors: Rampersaud Marsha
Published: September 2021

This paper theorizes that a process of identity transformation occurs when individuals enter prisons, whereby individuals become prisoners. I investigate how this identity transformation occurs through interaction with the prison’s architectural design. Prisons are posited as locations of purposeful spatial organization whose design evokes particular performances from those within and outside, and which actively contributes to the creation of the prisoner identity. This investigation reveals a carceral power at work which renders prisons sites of articulated and detailed control that exist within a broader set of institutional practices and relations of power aimed at the transformation of individuals. This discussion critically engages with the broader purpose of the prison: while prisons are meant to rehabilitate and reform prisoners, the structured architecture of the prison conflicts with this objective.

Authors: Semenenko S. I.
Published: September 2021

Annotation. An important measure of intensive care in patients with traumatic brain injury (TBI) is the use of pharmacotherapeutic agents with antioxidant properties. The aim of this study was to evaluate the effect of ademol compared with amantadine sulfate and 0.9% NaCl solution on the course of oxidative stress in the brain of TBI rats. The experiments were performed on 28 white male rats weighing 160-190 g. The experimental TBI model of severe severity was caused by the action of a carbon dioxide flow under pressure created using a gas balloon pneumatic gun. The therapeutic effect of ademol on model TBI was evaluated with a 2 mg/kg dose. The pseudoperated animals and control group received a 0.9% solution of NaCl and amantadine sulfate at a dose of 2 ml/kg and 5 mg/kg i/v. Data were processed using StatPlus 2009. We used the parametric criterion of t-Student, non-parametric criterion of W. White, paired criterion Ť. Wilcoxon, Fisher's angular transformation at p <0,05. In the course of the experiment, it was found that treatment of rats with TBI ademol leads to a decrease in the activity of lipid peroxidation and oxidative degradation of proteins (p<0.05) and promotes the normalization of the activity of antioxidant enzymes in cells of traumatically damaged brain (p<0.05). The use of ademol compared to amantadine sulfate and 0.9% NaCl solution was accompanied by a more significant decrease in the activity of lipid peroxidation and oxidative degradation of proteins and an improvement in the level of antioxidant enzymes in damaged brain of animals with TBI (p<0.05).

Annotation. “Voluntary childlessness” as a consequence of fear of infertility, doubts about the ability to cope with pregnancy in the presence of the disease, the hereditary nature of the disease and adverse effects on the fetus; improper medication; self-modification or discontinuation of therapy in patients with CIBD (chronic inflammatory bowel disease) are significant not only medical but also social problems that currently remain unresolved. The aim of this work is to provide up-to-date evidence for the optimal diagnosis and treatment of chronic inflammatory bowel disease before conception, during pregnancy and in the postpartum period. A detailed analysis of the social, somatic, gynecological and obstetric history of women with inflammatory bowel disease was performed. The examined patients were divided into the main group (ulcerative colitis) (n=40) and control groups (almost healthy women) (n=30). The first main clinical group underwent prophylactic therapy using a drug containing active folate of the 4th generation "Quatrefolic" (equivalent to 400 μg of folic acid), potassium iodide 1 table. per day and vitamin D 1000 IU per day, starting from the planning stage of pregnancy). The second major clinical group received, in addition to Quatrefolic and potassium iodide, vitamin D 4,000 IU per day during the pre-pregnancy phase and 2,000 IU per day during pregnancy and 1,000 IU per day in cases of placental dysfunction and anemia. The formation of observation groups was carried out by methods of continuous and selective analysis. Statistical processing of research results was performed using the software package Statistica 6.0. The obtained indicators were processed statistically with the determination of the arithmetic mean (M) and the error of the standard deviation (±m), at p<0,05. Risk ratio (RR) and confidence interval (CI) were determined with a given reliable probability p=95%. Comparison of groups by case frequency was performed using the exact Fisher test (two-way criterion). Pregnant women with ulcerative colitis have a better clinical efficacy of preventive therapy using the 4th generation active folate “Quatrefolic” (equivalent to 400 mcg of folic acid) and vitamin D 4000 IU at the pre-pregnancy stage and 2000 IU after pregnancy verification compared with active folate 4th generation “Quatrefolic” (equivalent to 400 mcg of folic acid) and vitamin D 1000 IU.

PRINCIPLES OF TRANSITIONAL JUSTICE
Authors: Andrii CHVALIUK , Borys BABIN
Published: September 2021

Background. The issue of reintegration of the temporarily occupied territories was emphasized by the President of Ukraine as one of the priority areas of work of the Commission on Legal Reform. Instructing to develop a concept of transitional justice in 2019, the President said that it should include measures to compensate victims of war, bring to trial those guilty of serious crimes, realize the right to receive the truth about the course of the conflict. However, neither the country’s leadership nor the scientific community has yet determined the principles on which these measures should be implemented. Analysis of recent research and publications has revealed that, when thinking about the principles of transitional justice policy, human rights activists and scholars use such language clichés as «directions», «measures», «main principles»,«postulates», «essence», «policy principles to support transitional justice». This creates some confusion that needs to be eliminated. The aim of this article is to formulate the principles of the Ukrainian model of transitional justice. Materials and methods. During the study, both general and special methods of cognition were used: dialectical, terminological, systemic, formal-logical, generalization, structural-functional, modelingand forecasting. The information base of the study was the norms of international law, national legislation and draft laws, expert opinions, works of domestic and foreign scientists. Results. The article considers the principles on which the Ukrainian model of transitional justice should be based. Taking into account the fact that at the normative and doctrinal levels the consolidation of the principles of the domestic model of transitional justice has not yet taken place, the author offers his vision of the system of principles of the domestic model of transitional justice and outlines promising areas for their practical implementation. Conclusion.The author believes that the basic system of principles of the domestic model of transitional justice should look like this: the primacy of international law; objective (judicial) truth; universal justice; post-conflict modernization of public relations; efficiency and timeliness. Keywords: transitional justice, principles, model, measures, directions, reintegration of temporarily occupied territories.

Published: September 2021

The article deals with the main difficulties that a researcher may face studying the legacy of the classical Urdu poet Mir Taqi Mir. During his life time Mir was accorded wide recognition as a great poet of North India and nowadays his ghazals are still popular and loved by Urdu speaking people. The main difficulties of a researcher concern many inaccuracies in biographic facts, principles of selecting ghazals to be analysed, the difficulties in translating ghazals to other languages and some other problems. The majority of papers on Mir are in Urdu. The study of Mir’s literary heritage by Russian philologists was practically frozen in the last century, and nowadays it seems relevant to continue it.
Narrative Structure and Content of Vietnamese Stories Regarding Tutelary Deities of Villages (thần tích): Case Study of the Story of Yết Kiêu Spirit
Authors:   Russian State University for the Humanities, Gordienko Elena V.
Published: September 2021

This article analyzes the Story of a fisherman Yết Kiêu (歇驕) who is worshiped as a tutelary spirit in villages of Northern Vietnam. Yết Kiêu is a semi-mythical character and he is widely credited with supernatural abilities and merits in war against the Mongols (1288). I investigate the text that belongs to thần tích genre (神). It is a manuscript written in Vietnamese at Yết Kiêu’s birthplace, which is the central place of his worship (on the basis of previous texts of the 16th–19th centuries). The Story of Yết Kiêu has a complex structure reflecting the history of the development of this particular text and the whole genre as well. The story can be divided in four parts differing in form and content: the folk layer (the oldest part), the historical narrative (likely compiled by court historiographers in the 15th–17th centuries), the legend of Yết Kiêu’s Mongolian bride (emerged evidently in a temple community during later centuries) and the description of Yết Kiêu’s cult (which appeared under the influence of the European research methods in the early 20th century). The article contains a fragment of the story translated into Russian.
QUALITY ASSURANCE IN PHARMACEUTICAL OPERATIONS

Published: September 2021

The specialized literature does not confer a consensual definition of the quality in the pharmaceutical procedures. Nevertheless, most definitions imply the satisfaction of eth customers’ needs. The customers of the pharmaceutical procedures are the patients and also the professional persons from the domain of health that prescribe, issue and administrate medicines. The pharmacist is a professional person who is in direct contact with the patient, being the first professional person to whom the patients address when the affection is a mild one and they need counselling regarding the medication or diagnostic. The more complex the medication of the patient is, the more probable the side effects shall be. The morbidity and mortality may be consequences at the error of medication. The appearance of some medicines increases directly proportional to the errors of prescribing the medication. The quality in using the medication implies the choice of the medicine, the optimization of the compliance of the patient with the treatment, avoiding side effects, assuring the therapeutical objectives. The possibilities of appearing the errors being numerous, it is easy to understand why the assurance and improvement of the quality of the pharmaceutical procedures are important aspects for pharmacists and patients. The present paper has as purpose the qualitative improvement of the pharmaceutical procedures by the help of the pharmacist, thus the pharmacy becoming a supplier of pharmaceutical care of the best quality

Authors: Iancu Irina Mihaela , Bucur Laura Adriana , Schröder Verginica , Apetroaei Manuela Rossemary
Published: September 2021

"The Lythrum salicaria L. plant, from the Lythraceae family, has multiple beneficial effects on the human body, through pharmacological properties imprinted by its secondary metabolites, namely tannins. Chitosan-based biomedical materials are of increasing interest precisely due to the uniqueness of their properties, namely biocompatibility, nontoxicity, biodegradability, antimicrobial and antioxidant nature. The combination of chitosan with the plant extract aimed at obtaining new matrices, with clearly superior characteristics, compared to each material (chitosan and plant extract). This could be due to the presence of amino groups in the structure of chitosan, known to be active at a pH slightly acidic and which could be chemically bound to the phenolic groups of tannic acids (the predominant components of the plant extract). The study aimed to obtain for the first-time mixtures of different concentrations of aqueous solutions of Lythri herba plant extract with standard chitosan 1 % in lactic acid (1 %) solution, which allowed achieving compatible and stable membranes. Microscopic evaluation of the membranes were made, following the uniformity of the surfaces, the homogeneity, the distribution of chitosan relative to the extract, and their stability in PBS saline buffer. The behavior of these membranes gives us a perspective on their use in dentistry and pharmaceuticals. In addition, the current paper has shown the existence of chitosan in the composition of the obtained membranes and their ability to maintain constant hydration and flexibility over a certain period."

Authors: Chis Timur , Petrache Stefan , Sapunaru Olga
Published: September 2021

"Oil pollution of surface and groundwater is an undesirable phenomenon but it is possible to happen. The pollutant can appear as a result of leaks from the transport pipelines, the damage of the oil extraction and processing installations, and the distribution states of the petroleum products. In the vast majority of interventions to combat pollution, polymeric sorbents are used which are spread over the pollutant and then washed with warm water. This technology does not completely clean the pollutants, and the polymeric sorbents are difficult to remove. Oil-cake (sunflower) is a grated residue after oil extraction and contains the amino acid lysine and high content of fiber and methionine. At a quantity of 100 kg of sunflower seeds, a processor obtains a quantity of 35 kg of residual mass consisting of a sunflower meal. This product can be used as a sorbent for petroleum products, being then used to produce green energy. The physical properties of two sorbent substances (sunflower oil and peat) are presented. Also, their adsorption capacities for four pollutants specific to the oil industry (gasoline, diesel, paraffin oil and sulfur oil) are analyzed, as well as the adsorption kinetics. The adsorption equations of the pollutants are also described."

Published: September 2021

Electrical research in geology is used quite widely and with great efficiency. The use of ready-made signal recorders for these purposes is possible, but not effective enough, since in any case, they need to be modified to provide additional functions. Such functions include the synchronization of measurements with signals from positioning systems GPS or GLONASS. This synchronization is necessary in order for the measurement results to be linked to actual space and time coordinates as accurately as possible. The same measurements taken at different times may give different results due to changes in the orientation of the Earth relative to the Sun and Moon, as well as for other uncontrollable reasons. The need to accurately determine the coordinates of the measurement is obvious. The creative team of the commonwealth of organizations, the key of which is the Siberian Branch of the Federal State Budgetary Institution of Science of the Federal Research Center “Unified Geophysical Service of the Russian Academy of Sciences”, carried out the development and initial testing of a specialized signal recorder for electrical research. The additional modification was required to eliminate the identified deficiencies. This paper reports the main technical solutions when creating this recorder, describes the modification ,and gives an example of using this recorder for field measurements.

Published: September 2021

The aim of the study was to assess the level of contamination of soil with strontium, rubidium and scandium in the solid waste deposits. The study was performed on soil samples collected from Moldova Noua, southwest of Romania, an area with historical anthropogenic history. The soil analysis was performed using X-ray fluorescence (XRF). The samples were collected from five collection points using a random pattern from around the illegal waste deposit and all analyses were performed in triplicate. To assess the influence of wastes on the soils concentration levels of strontium (Sr), rubidium (Rb) and scandium (Sc), were calculated contamination factors (CF), and pollution index (PIL) by reporting the concentration of the investigated elements of the upper earth crust concentrations and geo-accumulation index (Igeo) calculated by reporting the elements concentration values to a control sample, used as reference. The reference sample was collected from an area close to the waste deposit but located in a protected green area. The results show that from the investigated elements, scandium is the element of concern, the soil presenting a moderate contamination level with this element.
COMPARISON OF SUBJECTS OF THE URAL FEDERAL DISTRICT BY THE SHARE OF VEGETABLE COVER
Authors: Mazurkin Peter
Published: September 2021

The ecological consolidation of vegetation according to three classes of the UN soil cover (grass + shrub + trees) is considered. The ecological coefficient is calculated by dividing the share of vegetation by the share of changed land. For the rating, the forest-agricultural coefficient is convenient as the ratio of forest area to arable land. The ecological principle of the consolidation of 13 types of land is proposed, which makes it possible to carry out the ecological consolidation of the vegetation cover and altered human land. According to these proposed criteria, the ranking of the subjects of the Ural Federal District was carried out.

Published: September 2021

On the peach species, Springold variety, research was conducted on the influence of the F414 biological product on some physiological indexes and processes carried out on the foliar level, the area of culture being characterized by an accentuated thermo-hydric stress during the summer. Photosynthetic gas exchange, foliar transpiration and stomatal conductance were determined with the portable LC PRO + apparatus, and the leaf water forms were determined gravimetrically, the results obtained being correlated with the meteorological data from the vegetation period. Applying the F414 to the Springold variety resulted in the formation of a pellicle on the surface of the leaves, which, together with the action of the thermo-hydric stress specific to the area, caused stomate closure, reduction of CO2 supply, photosynthesis values being considerably lower compared to the control variant. As for foliar transpiration, the F414 product had a positive effect, the pellicle formed on the surface of the leaves, reducing the amount of water lost to the foliage. The application of this product has positively influenced drought resistance of the Springold variety, the percentages of the bound water being higher (5.1%) compared to the control variant (3.96%).
CAPILLARY RISE CHARACTERISTICS AND SALTWATER PROPAGATION IN FINE AGGREGATE: TOWARD DEVELOPING THE ANTI-SALINITY SHALLOW FOUNDATION
Authors: Truc Nguyen Ngoc , Hoang Nguyen Van , Tu Tran Ngoc
Published: September 2021

This study is carried out to determine the capillary rise over time of fine aggregate in different saline media. The obtained results showed that the capillary height in fine aggregate is inversely proportional to the salt concentration of the capillary solution. The aggregate that has a particle size over 2.0 mm shows the best ability to limit capillary rise. The capillary height of the aggregate gets the highest value when there is no salt in the solution and gets the lowest one with the solution at the highest salinity tested, i.e. 33.0 g/L. The obtained results on capillary characteristics lead to an idea of design a shallow foundation that has a function of anti-corrosion, anti-salinity proactively and effectively.

By studying the processes of adsorption of H+ and OH- ions from aqueous solutions, the acid-base properties of the surface of the solid phase of the most polluted technological product - the drain of the apatite concentrate thickener - the mineral composition of which is 90% apatite have been studied. The influence of the reagents present in the processing technology on the quantitative ratio of acid-base centres on the apatite surface has been evaluated. It has been shown that the interaction of these reagents with the mineral creates prerequisites for a greater efficiency of the anionic flocculant. The electro-surface properties of apatite treated with various reagents were studied using the laser Doppler electrophoresis method. The mechanism of fixation of ions present in the dispersion medium on the surface of apatite was studied by infrared spectroscopy. In order to determine the conditions under which various flocculants are in the most ionized state, studies were conducted on the change in the viscosity of the polyelectrolyte solution at different pH values. The position of the isoionic point for samples of cationic and anionic flocculants in the presence of reagents used in the apatite flotation and dehydration of apatite concentrate was studied. A research has been carried out on ""model"" and real suspensions in circulating water for a number of cationic, anionic and nonionic flocculants. The kinetic and concentration dependences of the flocculating capacity of the studied reagents were determined, which confirmed the high efficiency of the anionic type reagents"

The establishment and interpretation of diameter and height structures are essential for forest management decisions. This study aims to describe the diameter structure and spatial distribution of Pinus halpensis populations in the Chettaba state forest (Constantine, Algeria). The knowledge of these parameters is an essential step for their sustainable management. The diameter at 1.30 m from the ground and the total height of P. halpensis individuals were measured on 6 plots along an altitudinal gradient. The height structure shows that trees in the height classes between 5 and 10m have a very high density, indicating low natural regeneration. The total structure indicates that smaller trees are more abundant than larger trees (17.5<d≤27.5cm). These results contribute to the improvement of knowledge on current condition indicators of natural Pinus halpensis stands that can be used as a basis in the management of Chettaba forest

"The structure of various stands, defined as the diversity of trees in the stands, can be an indication of overall biodiversity and habitat suitability, be useful in predicting stand growth and provide stand details for forest inventories. In an effort to find sustainable resource management strategies, a study was conducted on the structural and ecological characteristics of stands in Chettaba forest (Algeria). In this study, six diversity indices were used to characterize the horizontal and spatial distribution of individuals in multi-species stands, using four plots, located in the Chettaba forest (East-North Algeria). The results obtained allowed us to note that P2 and P3 present similar average densities (600 feet/ha), the plots P1 and P4 present low average densities (250 feet/ha and 350 feet/ha). The average DBH values vary from 25.65 cm for the P2 stand to 30.61 cm for the P1 stand. The average basal area varied between 33.73 m²/ha (P3) and 18.92 m²/ha (P1). The Shannon and Weaver index reached its maximum in plot 4 with 8 species. The study allowed us to evaluate the floristic diversity of the forest. Moreover, it indicated the need for its integral protection for its dynamics towards a dense forest vegetation."
MODELING PRESENT AND PROSPECTIVE DISTRIBUTION OF PHYTEUMA GENUS IN CARPATHIAN REGION WITH MACHINE LEARNING TECHNIQUES USING OPEN CLIMATIC AND SOIL DATA
Authors: Mkrtchian Alexander
Published: September 2021

"Species distribution modeling can be effectively carried out using open data and data analysis tools with machine learning techniques. Modeling of the distribution of Phyteuma genus in the Carpathian region has been carried out with data from the GBIF database, climatic data from the Worldclim database, and soil properties data from Soilgrids soil information system. Spatial distribution modeling was accomplished with machine learning techniques that have marked advantages over more traditional statistical methods, like the ability to fit complex nonlinear relationships common in ecology. Four methods have been examined: Maxent, Random Forest, Artificial Neural Networks (ANN), and Boosted Regression Trees. AUC and TSS criteria calculated for testing data with cross-validation have been applied for assessing the performance of the models and to tune their parameters. ANN with a reduced set of predictor variables (6 from initial 21) appeared to fare the best and was applied for predictive modeling. Prospective data based on future climate projections from Worldclim were input to the model to get the prospective distribution of the plant taxon considering expected climate changes under different RCPs"

Mediterranean ecosystems are considered particularly sensitive to climate change. Any change in climatic factors affects the structure and functioning of these ecosystems and has an influence on plant productivity. The main objective of this work is to characterize one of the Mediterranean ecosystems; the Chettaba forest massif (located in the North-East of Algeria) from a vegetation point of view and their link with monthly variations using Landsat 8 satellite images from five different dates (June 25, 2017, July 27, 2017, August 28, 2017, October 15, 2017). The comparison of NDVI values in Aleppo pine trees was performed using analysis of variance and the use of Friedman's non-parametric test. The Mann-Kendall statistical method was applied to the monthly distribution of NDVI values to detect any trends in the data over the study period. The statistical results of NDVI of Aleppo pine trees indicate that the maximum value is recorded in the month of June, while the lowest values are observed in the month of August where the species studied is exposed to periods of thermal stress.

The economy of Latvia is experiencing rapid development in the European Union and is an active participant of the United Nations and North Atlantic Treaty Organization. In recent years there have been several changes in both sectors and national economic policy. The total population in Latvia was estimated at 1.9 million inhabitants in 2019 and a total GDP per capita was 63% of the EU average, the lowest GDP per capita in purchasing power parity was recorded in Bulgaria - 46% of the EU average, Romania - 60% and Croatia - 62%. Lithuanian and Estonian GDP per capita in 2019 was accounted for 74% of the EU average. Latvia has more than 12 theme parks, but the amusement offer is small. Most of the theme parks are mostly located in Kurzeme and Vidzeme. Attraction Parks historically evolved near the big cities, where the infrastructure is highly developed. The aim is to increase the influx of tourists in regions where tourism products are amusement parks, thus developing more local businesses and the city's environment, increasing the demand for an active economic environment, but regional laws often hinder this development.
