A reduction in the number of biological species can cause a loss of the integrity of the biosphere and its ability to maintain the most important characteristics of the natural environment. Therefore, scientific research and the development of practical recommendations in the field of conservation of biological diversity in forest management are currently of particular relevance. Measures to preserve biodiversity in forest management are reflected in the rules of timber harvesting, forestry regulations of forestries and forest development projects. The conservation of biological diversity in the course of logging operations is provided by allocating key biotopes – forest plots of a certain area, especially significant as habitats for rare species of animals and plants. The analysis of the Red Book of the Vologda Region showed that 29 % of rare species are confined to forest areas along watercourses. The study has been conducted at stationary sites within the boundaries of the Vologda Forestry of the Vologda Region (the Southern taiga area of the European part of the Russian Federation), represented by clear cuttings of 2018–2019 with the preserved key biotopes – forest areas along temporary water bodies. The average values for the plantations have been obtained on the basis of the materials from allotment and taxation of the cutting areas before felling. The work has been based on silvicultural and taxation, as well as ecological and biological methods of field evaluation and desk assessment. During the field studies (2023) in the key biotopes, a tally has been carried out by tree species, their diameters at chest height and categories of sanitary condition, with the determination of the average taxation indicators of the stands. The soils and the botanical composition of the live ground cover have been described. The species diversity and abundance of plant species in the key biotopes, as well as in the adjacent areas – in the cuttings and in the stands – have been determined. A higher number of species of taiga flora and the presence of rare plant species in the key biotopes, in contrast to the cuttings, have been established, which indicates the need to preserve the key biotopes during logging operations. Within the boundaries of the key biotopes studied, the average number of plant species in the buffer zone exceeds the number of species in the core of the biotope, the differences are statistically significant. Therefore, in the process of allotment of cutting areas, in addition to the allocation of the central part, or the core of the biotope, it is necessary to preserve a buffer zone as the area with the largest number of species.

The assessment of forest productivity in forestry and forest ecology has a long tradition, but in recent decades there has been a paradigm shift: the target function of forestry, consisting in wood cultivation, has shifted towards the biosphere-stabilizing function and the assessment of biomass and carbon sequestration capacity of forests. Equations and tables for assessing biomass at the stand level have an advantage as they can be used to characterize both the biomass of individual stands and their totality, as well as (when combined with the state forest inventory data) the situations in the forests throughout the country. The complexity of the work on assessing biomass of trees and stands has prompted researchers to use the existing tables of growth progress when compiling the tables of biological productivity of the stands using the recursive method. For the conditions of the northern and middle taiga of the Arkhangelsk Region, there are no tables of growth progress for gray alder biomass. The aim of this research is to study the growth progress of gray alder biomass in the stands of the Arkhangelsk Region. A series of sample plots has been laid to assess the above-ground biomass of the trees of this species. Based on the actual data from 50 model trees from 30 sample plots, the allometric models of the dependence of biomass fractions on the stem volume have been developed. The obtained models have been combined with the tables of growth progress for gray alder by quality class and the table of biological productivity of the species for the conditions of the Arkhangelsk Region has been drawn up. The results have been compared with the data on the biological productivity of gray alder in Belarus, Lithuania and Latvia. It has been shown that the biomass of the mature stands of gray alder of the 1st and 2nd quality classes in the Arkhangelsk Region is 3–9 % less than in Belarus and Lithuania. For the stands of the third and fourth classes, this difference increases to 29–48 %. Such differences in the biomasses of the compared regions can be explained by different zonal site conditions.

Archives of clones (ACs) of plus trees (PTs) are laid to preserve their genotypes. The genotype of each plus tree is unique, and its loss is irreplaceable. In addition, scientific observations are carried out in the archives, in particular, the selection of clones for forest seed orchards (FCOs) of increased genetic value (FSO-I,5). The aim of this research has been to study the dynamics of creating and preserving the archives of clones, as well as their state, in Russia in general and in the Republic of Karelia in particular. As of 2019 there were 31,514 plus trees in the Russian Federation, and the archives of clones covered an area of 573.6 ha, or 17 % less than in 1976. In the Republic of Karelia, despite discarding 40 % of them, as of 01.01.2023, there were 1,486 plus trees, including 1,100 trees of the most valuable forest species – Scots pine. Only 12.8 % of the progeny of this species grow in the archives of clones (8.4 % of a total of 1,695 selected Scots pine plus trees). For a full-fledged archive of clones (1,695 pcs. of the progeny of Scots pine plus trees), it is required to additionally plant 38.9 ha (in two repetitions – 81.3 ha) of trees. First of all, it is necessary to create the archives of clones of Scots pine from the plus trees listed in the register of the Republic of Karelia as of 2023 (1,110 pcs.). In this case, the area of additional planting will be 52 ha. To date, the selection inventory of forests in Russia as a whole and its regions, including the Republic of Karelia, has been partially completed, i.e. the selection of plus trees, considering the huge size of forested area, has also been carried out to a limited extent. Meanwhile, it is the plus plantations, plus trees and forest seed orchards created by their clone progeny that are a sample of the best phenotypic gene pool of the main forest-forming species, both in the regions of the RF and in the country as a whole. But over time these objects are aging, dying and being cut down. The best specimens may not always be preserved even in forest seed orchards and matrix plantations (MPs). Constant deforestation, a decrease in the age of felling, and the natural aging of certified plus tress necessitate the resumption of systematic selection of plus trees in the best ripening plantations of the Republic, especially its northern and central parts, and the cultivation of the best trees in the archives of clones in the form of clone progeny. This article indicates the importance of clone archives for preserving the valuable gene pool of forest woody plants and their use even in the event of the disappearance of plus trees in the places of selection and registration.

Published: April 2024

This study aims to investigate the influence of inclusive leadership and knowledge-sharing behavior on organizational citizenship behavior (OCB), mediated by job satisfaction and job involvement at the Financial Management Agency of Pidie District. The data were collected through questionnaires distributed to employees, and confirmatory factor analysis was conducted to test the indicators of the variables. The results reveal that Inclusive leadership and Knowledge sharing behavior affected Job Satisfaction, Work Engagement, and OCB; Job Satisfaction and Work Engagement affected OCB; and Inclusive leadership and Knowledge sharing behavior affected OCB through Job Satisfaction and Work Engagement. These findings prove that Job Satisfaction and Work Engagement are 2 variables that function as partial mediators in the model. So, these things explain that the model for increasing OCB at the Pidie District Financial Management Agency is a function of strengthening inclusive leadership, strengthening knowledge-sharing behavior, increasing job satisfaction, and increasing employee work engagement. This conclusion can be stated as a premise that is the basis for developing theory through further research.

In most recent time, the global landscape of supply chain management has experienced unprecedented challenges during the COVID-19 pandemic, which has significantly impacted the routine and smooth operations of different firms in the United States. This paper explains about the importance of artificial intelligence (AI) and machine learning (ML) in the mitigation of these disruptions and possible ways of improving supply chain security and its efficiency. This research adopted a questionnaire survey involving 281 managers, with the aim to comprehensively examine the current state of AI integration across the U.S. supply chain sector, with focus on some key components like real-time tracking, cost optimization, and risk management. A mixed method approach was adopted for this research, utilizing both inferential and descriptive analyses to unravel insights and trends into the role of AI in enhancing supply chain security. The results indicate that integrating AI, most especially through cost optimization, real-time tracking, and risk management components, emerges as a significant determinant of supply chain security in the United States. Real-time tracking technologies are identified as crucial for monitoring shipments and assets, enabling quick responses to security incidents, and ensuring end-to-end visibility throughout the supply chain. Despite the potential benefits, the study highlights challenges that hinder the widespread integration of AI technologies in the U.S. supply chain. The high cost of AI adoption and the limited availability of skilled personnel are major obstacles. To address these challenges, the paper proposes practical recommendations. Firstly, real-time tracking technologies are recommended to monitor shipments and assets, facilitating rapid responses to security incidents, and ensuring visibility across the entire supply chain. Furthermore, the paper suggests optimizing costs by investing in cost-effective security solutions. This includes leveraging AI for automated monitoring systems and adopting secure packaging measures. These strategies aim to minimize vulnerabilities without compromising security standards, offering a balanced approach to enhancing supply chain security while mitigating the financial implications associated with AI adoption.

El objetivo del estudio fue analizar la percepción de escolares de 8 a 12 años, de ambos sexos, distinto nivel socioeconómico (NSE) y estado nutricional, sobre la regulación de la publicidad de alimentos y bebidas azucaradas. En un estudio de corte transversal, se aplicó una encuesta previamente validada a 812 escolares (399 niños y 413 niñas) de NSE alto y bajo en 3 ciudades del país. Los datos se analizaron según NSE y estado nutricional. La obesidad fue más prevalente en los niños de NSE bajo, quienes veían más comerciales de alimentos y bebidas en televisión y los de NSE alto en Internet y celulares. Sobre el 65% de los escolares en ambos NSE llevaba dinero para comprar alimentos en el horario escolar. En los primeros meses de entrada en vigencia de la Ley 20.606, el 80% de los niños indicaron que les gustaba ser informados de lo que contenían los alimentos y los sellos Alto en Calorías, Alto en Grasas Saturadas y Alto en Sodio fueron significativamente más importantes para los de NSE alto. El sello Alto en Azúcares fue igualmente importante en ambos NSE. Estos resultados permitirán apoyar intervenciones de educación en nutrición y marketing social que motiven la alimentación saludable en niños, padres y profesores.
LINGUISTIC ECONOMY AND SYSTEMATIC CONSTRUCTION OF LANGUAGE

Published: April 2024

The article provides general information about language phenomena, artificial intelligence and their connection with knowledge, thinking, memory, etc. In addition, the approaches and opinions of scientists on these topics are presented and explained with the help of examples. The author states that the movement of thinking and the formation of thought is associated with cognitive activity, a process that ensures the reflection of reality directly in the mind. It is known that the formation of speech units and their understanding are the result of mental activity. The performance of this activity is directly related to the condition of obtaining linguistic knowledge. There is no way to know reality without linguistic knowledge, to lyrically express logical structures that reflect information about the current event-events. However, at the intersection of cognitive science, six fields of science are adjacent, and a single scientific goal is to be occupied with the search for a solution to the problems of concentration, processing and application of knowledge in natural and artificial systems. It seems-that interrelation between these areas does not take place in the same way, whereas, Artificial Intelligence and anthropological philosophy are directly related.Meanwhile, human cognitive activity should be considered not as a reflection of being as a mirror, but as a phenomenon that reflects the inner or outer essence of objects. The mental structure formed in the process of cognition –the content of the concept is occupied by character-features that have a clear appearance of exactly this type, and the same features lead in the linguistic reality of the concept.

Published: April 2024

Skin that is continuously exposed to sunlight can cause a reduction in the structure and elasticity of the skin and other bad effects, so it is necessary to have a skin protective agent, one of which is using sunscreen preparations. In the cosmetics sector, making products from natural ingredients is more profitable. They have a good tolerance for the skin because they do not cause severe irritation to sensitive skin. This research aims to determine the activity of red betel leaf ethanol extract as a sunscreen by looking at the SPF (Sun Protection Factor) value. The determination of the SPF value of red betel leaf ethanol extract was carried out in vitro using UV-Vis spectrophotometers at a wavelength range of 290 – 320 nm. Phytochemical testing is carried out to determine the content of chemical compounds that play a role in sunscreen activity. The research results show that the SPF values obtained from concentrations of 100, 200, 300, 400, 500, and 600 ppm, respectively, are 8.486 (extra-protection), 10,849 (maximum protection), 13,709 (maximum protection), 17.1 (ultra protection), 22 (ultra protection) and 25 (ultra protection). Based on the results of phytochemical tests, the ethanol extract of red betel leaves positively contains phenolics, flavonoids, alkaloids, tannins, saponins, steroids, and/or terpenoids.

Authors: Farizza Haniem Sohut  , Siti Khuzaimah Soid  , Anuar Ishak
Published: April 2024

This work offers illustrations of a graphical user interface (GUI) in MATLAB software. The governing partial differential equations are extremely useful in many industries, especially in analyzing the problem regarding this application through the analysis of the thermal and acceleration characteristics in a system. It is significant for determining whether the system is in the best momentum and whether the surface or ambient flow is good for the system to run. In addition, fluid mechanics is a subject required in certain universities (i.e., Engineering Faculty), thus it is important to have GUI as their learning tool. This GUI is a feature in MATLAB that is used to illustrate the velocity and temperature profiles and to display the numerical analysis on skin friction and local Nusselt numbers attractively and interactively. This interface can be designed by dragging and dropping the visual components onto the layout design. The GUI can be very helpful to undergraduate students in increasing their fundamental understanding of fluid flow phenomena.

Published: April 2024

The use of nanofluids as a coolant in automobile radiators is getting more attention for the radiator’s better performance. Continuous development in automotive industries has increased the demand for higher efficiency car engines. The addition of a radiator fin is one way to improve the efficiency of car engines. However, this study aims to prepare stable nanofluid and analyze the thermal physical and thermal performance of the nanofluid. Stable nanofluids were prepared using the two-step method, and the sedimentation of nanofluid was recorded to evaluate the nanofluids' stability. Single material nanofluid was compared to hybrid nanofluid and the most stable nanofluid based on the nanoparticle's sedimentation was decided. Nanofluid with less sedimentation was concluded as the most stable nanofluid among the mixture. KD2 Pro measured the thermal conductivity of nanofluid after confirmation of the nanofluid stability. A nanoparticle and base fluid chosen were based on the previous study. Al2O3 and TiO2 were dispersed in ethylene glycol and graphene: TiO2 dispersed in the mixture of EG: Distilled water (48:32) have been proposed in this study to improve the radiator performance. The factors affecting the thermal conductivity were studied, and the effect of volume concentration on the thermal conductivity of a nanofluid to transfer heat was also highlighted. An increase in volume concentration would also increase the thermal conductivity of nanofluid and thus increase radiator performance. The equation correlation of volume concentration and weight percentage equation was also proposed and investigated, hence used to prepare the sample of nanofluid.

Published: April 2024

The global energy structure is transforming, and new energy vehicles are becoming the future of the automobile industry. However, the development of charging piles and related facilities has not kept pace with the growth of new energy vehicles. This study uses the gated recurrent unit network and the whale algorithm to construct a high-performance charging pile fault prediction model. The proposed model, which utilizes the whale algorithm to prevent the gated recurrent unit network from falling into local optima, demonstrates improved predictive information extraction and prediction ability. The experimentally verified results indicate that the proposed model achieved 92.02% prediction accuracy, 85.66% recall, and 93.87% F1 value. Additionally, the proposed model demonstrates excellent computational ability with an average running time of under 5 minutes on both datasets. This result is a substantial reduction from the control model's running time. The experimental findings show that the study's suggested model has a good ability to anticipate fault data. Its sophistication is verified by comparative tests, which can provide a reference for subsequent research.

Effects mobilizing affects
Authors: Faro Inês
Published: April 2024

This article aims to show the many ways in which the affective tone of the short story ‘Sólo vine a hablar por teléfono’ (1992) [‘I only came to use the phone’] ([1992] 2006) by Gabriel García Márquez is produced, while also reflecting on the significance of adopting such a critical approach. To do so, I draw on contemporary affect theory, particularly on Sianne Ngai’s view of ‘affective tone’ as an expansion of affects as effects, and on Jane Bennett’s concept of ‘vital materialism’. The story tells the journey of a Mexican woman who is institutionalized and subjected to unimaginable abuses during Franco’s dictatorship in Spain. By focusing on the author’s use of literary effects and considering the aesthetics and the political together, this analysis reveals how negative or strange feelings are multiply generated, contributing to create a pervasive sense of uncanniness both within the text and in the reader. I conclude by arguing that an approach that considers how
e
ffects mobilize
a
ffects ultimately exposes how great fiction, through the mechanics of the text, can efficiently deploy transhistorical and trans-spacial structures in the operation of affects related with processes of dehumanization and loss of agency.
GLOBAL PATTERNS AND EXTREME EVENTS IN SOVEREIGN RISK PREMIA: A FUZZY S DEEP LEARNING COMPARATIVE

Published: April 2024

Investment in foreign countries has become more common nowadays and this implies that there may be risks inherent to these investments, being the sovereign risk premium the measure of such risk. Many studies have examined the behaviour of the sovereign risk premium, nevertheless, there are limitations to the current models and the literature calls for further investigation of the issue as behavioural factors are necessary to analyse the investor’s risk perception. In addition, the methodology widely used in previous research is the regression model, and the literature shows it as scarce yet. This study provides a model for a new of the drivers of the government risk premia in developing countries and developed countries, comparing Fuzzy methods such as Fuzzy Decision Trees, Fuzzy Rough Nearest Neighbour, Neuro-Fuzzy Approach, with Deep Learning procedures such as Deep Recurrent Convolution Neural Network, Deep Neural Decision Trees, Deep Learning Linear Support Vector Machines. Our models have a large effect on the suitability of macroeconomic policy in the face of foreign investment risks by delivering instruments that contribute to bringing about financial stability at the global level.
Beyond the Background: Gravitational-wave Anisotropy and Continuous Waves from Supermassive Black Hole Binaries
Authors: Gardiner Emiko C. , Kelley Luke Zoltan , Lemke Anna-Malin , Mitridate Andrea
Published: April 2024

Pulsar timing arrays have found evidence for a low-frequency gravitational-wave background (GWB). Assuming that the GWB is produced by supermassive black hole binaries (SMBHBs), the next gravitational-wave (GW) signals astronomers anticipate are continuous waves (CWs) from single SMBHBs and their associated GWB anisotropy. The prospects for detecting CWs and anisotropy are highly dependent on the astrophysics of SMBHB populations. Thus, information from single sources can break degeneracies in astrophysical models and place much more stringent constraints than the GWB alone. We simulate and evolve SMBHB populations, model their GWs, and calculate their anisotropy and detectability. We investigate how varying components of our semianalytic model, including the galaxy stellar mass function, the SMBH–host galaxy relation (M
BH–M
bulge), and the binary evolution prescription, impact the expected detections. The CW occurrence rate is greatest for few total binaries, high SMBHB masses, large scatter in M
BH–M
bulge, and long hardening times. The occurrence rate depends most on the binary evolution parameters, implying that CWs offer a novel avenue to probe binary evolution. The most detectable CW sources are in the lowest frequency bin for a 16.03 yr PTA, have masses from ∼109 to 1010
M
⊙, and are ∼1 Gpc away. The level of anisotropy increases with frequency, with the angular power spectrum over multipole modes ℓ varying in low-frequency C

ℓ>0/C
0 from ∼5 × 10−3 to ∼2 × 10−1, depending on the model; typical values are near current upper limits. Observing this anisotropy would support SMBHB models for the GWB over cosmological models, which tend to be isotropic.

The deposition of energy and momentum by supernova explosions has been subject to numerous studies in the past few decades. However, while there has been some work that focused on the transition from the adiabatic to the radiative stage of a supernova remnant (SNR), the late radiative stage and merging with the interstellar medium (ISM) have received little attention. Here, we use three-dimensional, hydrodynamic simulations, focusing on the evolution of SNRs during the radiative phase, considering a wide range of physical explosion parameters (

). We find that the radiative phase can be subdivided in four stages: A pressure-driven snowplow phase, during which the hot overpressurized bubble gas is evacuated and pushed into the cold shell; a momentum-conserving snowplow phase that is accompanied by a broadening of the shell; an implosion phase where cold material from the back of the shell is flooding the central vacuum; and a final cloud phase, during which the imploding gas is settling as a central, compact overdensity. The launching timescale for the implosion ranges from a few 100 kyr to a few Myr, while the cloud formation timescale ranges from a few to about 10 Myr. The highly chemically enriched clouds can become massive (M

The mouthparts and protarsi of adult rove-beetles of the Staphylinine group are examined in detail. We provide descriptions and image plates based on scanning electron micrographs taken from 36 species representing all 10 subfamilies comprising this large staphylinid subunit. We establish groundplan features of the mouthparts for the Staphylinine group and discuss, in detail, aspects and functions of structures that compose the feeding apparatus. A phylogenetic scheme is used to conduct an ancest﻿ral character reconstruction of the morphological characters. The potential groundplan features of the characters rendered in our parsimony analysis for the Staphylinine group are: labrum subquadrate or longer than wide; mandible without subapical teeth and retinaculum, with prostheca present, not forming lobe-like projection, and with a mola; maxillary palpomere 4 well-developed, fully sclerotized, similar in width to palpomere 3; ‘glossa’ integrated with prementum plate, sometimes represented by pairs of sensilla basiconica; ‘paraglossa’ with unmodified antero-lateral lobes; labial palpomere 3 from as wide to half as wide as penultimate palpomere. To explain the shape variation of the mandibles, a geometric morphometric analysis was carried out. A character mapping analysis of mandible shapes revealed a trend in the Staphylinine group toward a falcate shape with a narrow base, typically present in some predatory species.

Citrus fruit is widely grown in Indonesia. The skin of the fruit contains essential oils which can be used as aromatic ingredients in the perfume, pharmaceutical and culinary industries. Orange peel oil, extracted from different species, has different organoleptic qualities, specific gravity, refractive index value, acid number, ester number and solubility in 96% ethanol. This research aims to determine the differences in the essential oil components of sweet orange, lime and lemon peels and to determine the composition of commercial orange peel oil products. The method used to determine the differences in orange peel oil components is ATR-FTIR spectroscopy combined with two chemometric methods, PLS and PCA, to prove the differences quantitatively and qualitatively. The results of the PLS combination FTIR analysis showed that the most optimal wave number was shown in the 1450–1650 cm-1 area with an RMSEC value of 0.00553, then continued with PCA which showed the separation between samples. Results confirmed that the chemometric model effectively differentiated between essential oils from sweet orange, lime and lemon peels and those available on the market.
Why and how did LifeWatch emerge?
Authors: Los Wouter
Published: April 2024

The original vision on what later became LifeWatch ERIC started about a quarter of a century ago in 1996. In those days, the promise of digital technologies entered biodiversity and ecosystem research. Not only by digitiing relevant information, but also with applications to process such data. While several (inter)national initiatives embarked on specific topics, there was also an idea that the upcoming view on grid computing provided attractive solutions for federated data sources, together with a strong computing capacity. This paper presents the history from conception to early actions, until actual preparations towards a research infrastructure on the European scale.

A new species of gekkonid, Hemiphyllodactylus gengmaensissp. nov., is described based on six specimens from Gengma Dai and Wa Autonomous County, Yunnan, China. The new species can be distinguished from its congeners by a significant genetic divergence of greater than 9.7% in the mitochondrial ND2 gene and a combination of the following characters: a maximum SVL of 43.24mm; 8 or 9 chin scales; six circumnasal scales; 2 or 3 internasal scales; 9–11 supralabial scales; 8 or 9 infralabial scales; 11–18 dorsal scales; 8–10 ventral scales; a manual lamellar formula of 5–5–5–4 or 5–6–5–4 and a pedal lamellar formula of 5–5–6–5; 20–25 precloacal and femoral pore-bearing scales contiguous in males; dark postorbital stripes or striping on body; dark dorsal transverse blotches present; and a brown postsacral mark bearing anteriorly projecting arms. The discovery of this new species brings the number of Hemiphyllodactylus species in China to 15.

Patients with diabetes often lack the necessary knowledge, leading to inadequate behavior in preventing wounds. To overcome the limitations of traditional learning methods, it is crucial to adopt the flipped classroom approach for effectively educating diabetic patients about wound prevention. This study aimed to explore the relationship between the environment, learning infrastructure, and the flipped classroom learning method among patients with Diabetes Mellitus (DM). Employing a cross-sectional design, the study encompassed patients with DM aged 40-55 years from both genders. A total of 120 patients were selected through purposive sampling techniques. The variables investigated included education factors and the flipped classroom method, which were assessed using a modified questionnaire developed by the researchers and validated for reliability. Data analysis was conducted utilizing Spearman rank analysis. Concerning education factors, 80% of the participants reported having a supportive environment, while 82.5% indicated having access to good learning infrastructure. Regarding the flipped classroom method, 35.8% of the respondents stated that its application in educating patients with DM in the community was effective. There was a statistically significant relationship between the environment and infrastructure and the flipped classroom approach in patients with DM (p-value<0.05). Enhancing educational factors such as the environment and infrastructure can improve the effectiveness of the flipped classroom method in educating patients with DM. Moreover, promoting health literacy could further enrich the learning experience for diabetic patients, ultimately bettering their behavior and management of the condition. Future research on the flipped classroom learning approach for DM should focus on patient engagement and cultural adaptation to improve overall patient outcomes and the effectiveness of the healthcare system.
