In brief

To save endangered rhinoceros species, assisted reproductive technologies are warranted. We here report in vitro blastocyst generation of the Near-Threatened Southern white rhinoceros and, for the first time, also of the technically Extinct Northern white rhinoceros.

The Anthropocene is marked by a dramatic biodiversity decline, particularly affecting the family Rhinocerotidae. Three of five extant species are listed as Critically Endangered (Sumatran, Javan, black rhinoceros), one as Vulnerable (Indian rhinoceros), and only one white rhino (WR) subspecies, the Southern white rhinoceros (SWR), after more than a century of successful protection is currently classified as Near Threatened by the IUCN, while numbers again are declining. Conversely, in 2008, the SWR’s northern counterpart and second WR subspecies, the Northern white rhinoceros (NWR), was declared extinct in the wild. Safeguarding these vanishing keystone species urgently requires new reproductive strategies. We here assess one such strategy, the novel in vitro fertilization program in SWR and – for the first-time NWR – regarding health effects, donor-related, and procedural factors. Over the past 8 years, we performed 65 procedures in 22 white rhinoceros females (20 SWR and 2 NWR) comprising hormonal ovarian stimulation, ovum pick-up (OPU), in vitro oocyte maturation, fertilization, embryo culture, and blastocyst cryopreservation, at an efficiency of 1.0 ± 1.3 blastocysts per OPU, generating 22 NWR, 19 SWR and 10 SWR/NWR hybrid blastocysts for the future generation of live offspring.

Antigüedad y contexto sociocultural del jade en Costa Rica
Authors: Solís Del Vecchio Felipe , Sánchez Herrera Luis
Published: September 2023

Se presenta una revisión de contextos funerarios de La Regla (P-30 LR) y Huiscoyol (P-1726 Hs), dos sitios arqueológicos ubicados en la banda occidental del golfo de Nicoya en Costa Rica. Los conjuntos artefactuales en ambos sitios destacan por la presencia de metates trípodes planos con decorados de aves y colgantes celtiformes o “dios-hacha” ave. Doce fechamientos 14C a partir de madera, restos carbonizados y huesos humanos sitúan esta evidencia en un rango entre 800- 200 a.C., lo que los convierte en los contextos conocidos más antiguos con jade en Costa Rica. Esta información confirma que la producción de jade en Costa Rica se remonta al menos a 500 a.C. De igual forma, la producción cultural adscrita a dichos contextos advierte rasgos distintivos que los separan de desarrollos posteriores. Se espera que esta evidencia aporte en favor de modelos mejor sustentados sobre la inserción del jade y sus efectos en los sistemas sociales e ideológicos locales, así como a esclarecer el carácter de los vínculos tempranos con poblaciones mesoamericanas y del sur de Centroamérica.

Published: September 2023

Introdução: Devido a infecção congênita, a criança com microcefalia possui grandes limitações de sua condição de saúde. Estas limitações fazem com que a criança necessite de maior atenção de saúde e domiciliar.  Geralmente, a mãe torna-se cuidadora principal desta criança, esse papel pode levar a sobrecarga com prejuízos em sua qualidade de vida.
Objetivo: Analisar sobrecarga do cuidado e a qualidade de vida de mães ou cuidadoras principais de crianças com microcefalia relacionada à infecção congênita.
Método: Estudo transversal, correlacional, realizado com 105 participantes do estado de Sergipe, Brasil, durante o período de outubro de 2017 a abril de 2018, através da aplicação questionários: sociodemográfico, WHOQOL-Bref e Sobrecarga do cuidador. Para análise estatística foram utilizados testes ANOVA, teste t e Person (r).
Resultados: A totalidade dos participantes era do sexo feminino, 39 % foram classificadas com sobrecarga severa e 30,5% com sobrecarga intensa. A média total da sobrecarga (49,47) indica classificação de moderada à severa. Houve uma forte associação (p<0,0001) entre os níveis de sobrecarga e os domínios da qualidade de vida, sendo o de maior prejuízo o ambiental (36,57) e o físico (38,53). Foi observada uma correlação significativa e inversamente proporcional (r=-0,547, p<0,0001) entre a qualidade de vida e a sobrecarga do cuidador.
Conclusão: As mães sofrem sobrecarga severa e intensa que pode levar a repercussões negativas em sua qualidade de vida. A enfermagem pode contribuir na criação e implementação de linhas de cuidados específicas para estas mulheres com ênfase na promoção da saúde física, mental e melhora da qualidade de vida.

Introduction: The type of land use surrounding the remnants of tropical forest may generate changes in the characteristics of plant populations and communities. Consequently, there may be a significant reduction in processes of pollination and diasporas dispersion. Therefore, causing changes in some parameters of seed rain. Objective: To characterize and compare seed density, species richness, floristic composition, habit, dispersal syndrome, and successional category of seed rain between urban and rural fragments of Atlantic Forest, in the 2015 and 2016 weather seasons. Methods: The study areas were defined after mapping and quantification of urban and rural occupations around the remnants, based on satellite images. In each fragment, were installed 36 collectors of 0.25 m2. The material was collected monthly during two consecutive years. Results: Seed rain richness was higher in the urban fragment during the rainy season in the two years, whereas it was similar between the fragments in the dry season. The seed density in the rural fragment was higher than in the urban during the rainy season; did not vary in urban between years or between seasons; and it was higher in the rural fragment in the rainy season of one year. There was a difference in the floristic composition of the seed rain between the fragments along time. The variations in the functional attributes of habit, dispersal syndrome, and successional category, were explained by the variables fragment, season, and year. Conclusions: Differences in the characteristics of the seed rain between the fragments might reflect the spatial and temporal heterogeneity, due to the diverse uses of the soil and external pressures (anthropogenic actions) present in the surroundings of the forest fragments and temporal variation in precipitation.

Introduction: Oral health disorders in a pregnant woman have an adverse impact on the child’s health. A high maternal level of cariogenic bacteria can significantly increase the risk of tooth decay in the child. There is a positive correlation between increased plaque accumulation and premature birth and also low birth weight. Aim and methods: The aim of this study was to discuss the level of knowledge on the aetiology and prevention of tooth decay among pregnant women based on an original survey conducted in 2022 and to compare the results with a survey conducted in 2015 under the affiliation of the Warsaw Medical University, entitled “Awareness of pregnant women about preventing early childhood caries”. Both studies were subjected to a statistical analysis using Spearman’s rank correlation (p < 0.05). Additionally, PubMed data and current literature were used in writing this paper. Literature review: The analysis in both cases revealed a positive correlation between the level of knowledge and the education level of the respondents. In the 2015 group, 10% of expectant mothers knew when their first dental visit should occur, while this percentage rose to 51.9% in the 2022 group. The increase in the level of knowledge is also evident when considering questions about oral care before tooth eruption. Summary: The level of knowledge on the aetiology and prevention of tooth decay among pregnant women has increased compared to previous years and can be considered high. Further education is still needed.
Comparative Study on the Optimal Topologies
Authors: Tóth Bálint , Bruggi Matteo , Lógó János
Published: September 2023

The topology optimization is a leading tool in structural design. Due to the rapidly spreading need of the industry, commercial software are available in the market. Generally, these software are suitable for solving one subtask (preprocessing, postprocessing, stress calculation, etc.) but need some user manipulation to interconnect to one that is better for some other subproblem. This is the reason why we write a study on the available software and make suggestions on their usability. The purpose of this research is to briefly introduce selected software such as Rhino 3D, Grasshopper, Peregrine, Karamba, Galapagos, polyTop and PolyStress using topology optimization theory. Due to the demand to apply them for industrial applications, the additional goal is to make suggestions to make these software programs more user-friendly and to create algorithms to connect with software used in the industry, such as Consteel. This work also discusses the connected algorithms and optimization methods such as layout optimization by Peregrine, and topology optimization by polyTop and PolyStress. Several illustrative videos are provided as supplements. In addition to the text of this paper one can see demonstrations of the applications by the use of the provided YOUTUBE links.
The House We Live In: Virtue, Wisdom, and Pluralism
Authors: Segall Seth Zuihō
Published: September 2023

The values of liberalism, pluralism, and democratic governance are under sustained attack from right-wing Christian fundamentalists, white ethnonationalists, and economic populists. At the same time, liberal democracies are failing at cultivating and transmitting the values, wisdom, and virtues that are the perquisites for individual and collective flourishing. Liberal democracies seem increasingly unable to negotiate diverse visions of the good life rooted in regional, ethnic, racial, religious, generational, and socioeconomic differences. Aspiring autocrats and social media organizations exploit these divisions to enhance their power or profit, resulting in increased tribalization and affective polarization. Solving these problems requires a renewed understanding of human flourishing and the wisdom and virtues that make it possible. The House We Live In explores the commonalities underlying three classical approaches to virtue ethics—Aristotelean, Buddhist, and Confucian—to develop a flourishing-based ethics capable of addressing the problems of liberal democracies. The book examines the moral and intellectual virtues that promote flourishing, the diversity of ways in which we may flourish, and the factors all flourishing lives share. It shows how a flourishing-based ethics can serve as a corrective to the historical Western over-emphasis on individualism at the expense of community. Finally, it addresses problems in domestic and foreign policy and the difficulties in talking to each other across the political divide from a flourishing-based perspective. The book is a reaffirmation of pluralism, the liberal democratic tradition, and the necessity of a pragmatic approach to living together despite seemingly incommensurable differences.
The Relationship between Features of Foot Posture, Thickness of Intrinsic Foot Muscles and Dynamic Postural Stability
Authors: Shin Gyucheol , Kim Taeyoung , Pyi Seoyoung , Chun Woochan , Park Sookyoung
Published: September 2023

PURPOSE: This study aimed to determine the correlations between foot posture features, intrinsic foot muscles (IFMs) thickness, and dynamic postural stability.METHODS: Forty-one male participants were divided into two groups according to quantified foot postures using the Foot Posture Index (FPI-6) scores: the neutral foot group (FPI-6 score: 0 to +5) and the pronated foot group (FPI-6 score: >+6). The IFMs thickness was measured using ultrasound images of the flexor digitorum brevis (FDB), flexor hallucis brevis (FHB), and abductor hallucis muscles. To investigate the association between IFMs thickness and dynamic postural stability, the Biodex Balance System (BBS) was used in a single-leg stance position with both the eyes open and closed.RESULTS: In the BBS tests, the pronated foot group demonstrated significant results in the eyes-closed condition (p<.05). In particular, the differences between the eyes open and closed conditions in postural stability indices were significantly greater in the pronated foot group than in the neutral foot group (p<.05). No significant differences in IFMs thickness between the two groups were observed; however, some subdomains of the FPI-6 demonstrated significant positive correlations with postural stability indices and significant negative correlations with IFMs thickness (p<.05). The talonavicular joint was associated with FDB thickness (R=-0.311). Moreover, the forefoot was correlated with FHB thickness (R=-0.327).CONCLUSIONS: The aforementioned results suggest that dynamic postural stability and IFMs thickness are affected by the foot type. Although no significant differences in IFMs thickness were observed, dynamic postural stability and IFMs thickness reduced as the foot displayed features of pronation. This indicates that postural control ability and IFMs are vulnerable to changes in foot posture.
Effects of Regular Aerobic Exercise Interventions on Decreased Cerebral Blood Flow-Induced Mild Cognitive Impairment
Authors: Lee Dong-Hyun , Sung Soon-Chang , Hong Kwang-Seok
Published: September 2023

PURPOSE: Decreased cerebral blood flow (CBF) is a common symptom in older adults with mild cognitive impairment (MCI). Aerobic exercise is a promising therapeutic intervention for delaying or ameliorating age-related CBF deterioration in older individuals. The review outlines the differences in CBF between healthy older individuals and those with MCI, as well as the benefits of aerobic exercise in augmenting CBF in older adults.METHODS: We used academic search engines, including PubMed, Web of Science, Scopus, Google Scholar, and the Wiley Online Library, to identify studies demonstrating alterations in CBF with aging and the preventive and therapeutic effects of aerobic exercise on CBF in older adults. The keywords included ‘mild cognitive impairment,’ ‘elderly or older people,’ ‘cerebral blood flow,’ ‘cerebral perfusion,’ and ‘aerobic exercise.’RESULTS: Aerobic exercise improves or maintains health by enhancing CBF and cognitive function in healthy older individuals. The beneficial impact applies to older people with MCI, although research has been inconsistent regarding aerobic exercise-induced alterations in CBF.CONCLUSIONS: Aerobic exercise is a promising treatment for MCI in older adults and promotes CBF and cognitive function. However, some studies have reported inconsistent findings regarding changes in CBF. The inconsistencies may be due to several factors, including health and age. Further investigations are warranted to delineate the effects of aerobic exercise on CBF in older adults with MCI.

Published: September 2023

PURPOSE: Resistance exercise is an effective behavioral intervention for improving skeletal muscle mass and strength, and preventing sarcopenia. However, the effects of resistance exercise on arterial stiffness remain controversial. This study aimed to organize and analyze the effects of resistance training intensity on arterial stiffness in healthy adults without overt clinical disease.METHODS: A thorough literature search was conducted to retrieve original research articles between 2000 and 2023 using the PubMed, Web of Science, and Google Scholar databases.RESULTS: Long-term low-intensity resistance training (RT) was deemed a safe exercise intervention that can maintain or decrease arterial stiffness and increase muscle strength. Moreover, moderate-intensity RT was effective in improving muscle strength and hypertrophy but did not reduce arterial stiffness. High-intensity RT was an excellent intervention for enhancing muscle strength. However, a potential risk of increasing both central and peripheral artery stiffness in young adults was present.CONCLUSIONS: Compared to low-intensity RT, moderate-to-high-intensity RT was more effective in improving muscle strength and hypertrophy, but may increase arterial stiffness.
PARA ALÉM DE ELEIÇÕES REGULARES: DEBATE SOBRE O CONTEXTO DEMOCRÁTICO EM SÃO TOMÉ E PRÍNCIPE
Authors: Santos Ayolsé Andrade Pires dos , Marroni Etiene Villela
Published: September 2023

Após a tomada de independência em julho de 1975, São Tomé e Príncipe viveu sob um regime monopartidário. Dado o fracasso socioeconômico, verificado durante os 15 anos do monopartidarismo, e conflitos políticos entre membros do partido impulsionaram o processo de democratização no país em 1990. Passados mais de 30 anos da implementação da democracia, verificaram-se diversas falhas no seu processo. Por mais que a democracia em São Tomé e Príncipe tenha se reestruturado, a organização do Estado não conseguiu dar respostas aos problemas sociais que assolam o país. Desde que foi implementada a democracia, o país tem realizado eleições regulares, sem quaisquer conflitos de reconhecimento ou aceitação dos resultados das eleições entre os partidos, o que comprova, de certa forma, o bom funcionamento da democracia. Nesse contexto, pergunta-se: por que São Tomé e Príncipe, sendo um país democrático e com eleições regulares, o subdesenvolvimento tem sido sua principal característica? Por meio do método de análise bibliográfica, este estudo objetivou, de modo mais amplo, a uma reflexão do atual estado da democracia em São Tomé e Príncipe e a sua incapacidade na promoção do desenvolvimento socioeconômico. Quanto aos objetivos específicos, pretendeu-se: a) discutir a instabilidade política, que configura obstáculo ao avanço da democracia e b) verificar a fraca participação da sociedade civil no sistema democrático que contribui para o atual estado de pobreza em São Tomé e Príncipe. Nesse estudo, os dados coletados e analisados foram dados secundários, o que permitiu a elaboração de gráficos e tabelas viabilizando a nossa análise.
CONSELHOS NACIONAIS DE POLÍTICAS PÚBLICAS FRENTE À ALTERNÂNCIA PRESIDENCIAL
Authors: Lima Karime Pereira Ribeiro
Published: September 2023

O objetivo do trabalho é responder a seguinte pergunta: como os conselhos nacionais são impactados pelas mudanças políticas, mais especificamente, pela alternância presidencial? Primeiro, é estabelecido um diálogo com a literatura do neoinstitucionalismo histórico para entender como são caracterizadas as mudanças e as continuidades políticas e institucionais. Após isso, verificamos o que a literatura mobiliza como variáveis explicativas para as mudanças. Argumentamos que a alternância presidencial pode constituir uma mudança política e, em seguida, analisamos como os conselhos podem refletir a alternância presidencial. O diagnóstico preliminar é de que o impacto das alternâncias partidárias e presidenciais sobre os conselhos não foi suficientemente explorado. Por isso, optamos por voltar às bases teóricas que influenciam a literatura que aborda a desinstitucionalização e a resiliência dos conselhos nacionais, de forma a entender quais fatores explicativos são mobilizados no que diz respeito às recentes modificações que afetaram a participação em nível nacional. Nesse sentido, pretendemos avançar na análise dos fatores que permitem aos conselhos serem resilientes em períodos de mudança.
STUDY OF FLUID MOTIONS AND THERMAL PERFORMANCE OF WATER AND ACETONE OSCILLATING HEAT PIPES USING NEUTRON IMAGING
Authors: Yoon Il , Winholtz Robert A. , Ma Hongbin
Published: September 2023

Quantitative analysis of fluid motion in an oscillating heat pipe (OHP) is essential to better understand fluid flow and heat transfer mechanisms in an OHP. Two copper OHPs filled with water and acetone respectively were investigated by a neutron imaging technique to visualize the fluid motions in the OHP. Temperatures on the OHP surface were measured while neutron images were taken simultaneously. Algorithms to determine the degree of activity and the interface passing count were developed to analyze fluid motions quantitatively from the neutron images. Then, the degree of activity and the interface passing count were compared with temperatures. The results showed that there are patterns of temperature change before and after start-up of the oscillation motions. The acetone OHP showed better thermal performance at a similar heat input, while the water OHP showed better thermal performance at a similar degree of activity. Interfaces in the acetone OHP oscillate more frequently and travel further. Low latent heat at low heat input, low viscosity, and high thermal conductivity are preferred for the working fluid to achieve better thermal performance.
NUMERICAL SIMULATION OF HEAT TRANSFER IN A SQUARE CAVITY FILLED WITH HYBRID NANOFLUID
Authors: Salhi Hicham , Chafai Nadjib
Published: September 2023

This study uses numerical simulations to investigate the characteristics of laminar natural convection
in a square cavity filled with a mixed nanofluid containing Ag and Ag-TiO2 solid spherical nanoparticles.
The cavity contains one heat source and one heat sink, and the cavity walls are adiabatic. The fluid is a water-based hybrid nanofluid. The temperature in the cavity is randomized using a random function. The main parameters, including volume fraction of nanoparticles, temperature type, and type of hybrid nanofluid, are varied and analyzed using the finite volume method. The numerical results
are compared with previous studies, and a good agreement is observed. The obtained results show that the addition of nanoparticles significantly enhanced the heat transfer in the cavity (φ = 0.1%). In addition, the larger the Rayleigh number, the more obvious the influence of temperature type. Also, the average Nusselt number increases as the volume fraction increases, and the best results are obtained from the (Ag-TiO2)/water hybrid nanofluid.

Published: September 2023

Lisianthus has long-lasting, white, blue-purple, velvet or pink flowers. Varieties that can be used in pots, outdoors, or cut flowers are widely used and it is essential to develop new varieties to increase their commercial value. Breeding studies with classical methods can take a long time in lisianthus. Techniques to create variation in these plants and facilitate their reproduction always contribute to shortening the breeding period and one of the best known of these methods is plant tissue culture. This study aimed to investigate the micropropagation possibilities in lisianthus and examine the effects of auxin and cytokinin applications and doses on shoot reproduction. Supplemented with 10 different plant growth regulators in Murashige and Skoog (MS) medium, leaf explants from lisianthus plants that were germinated under in vitro conditions (seedlings) were cultivated. 6-benzyl aminopurine (BAP) was utilized in 5 doses (0.5, 1.0, 2.0, 3.0, and 4.0 mg L-1) alone in the first 5 groups. Naphthalene acetic acid (NAA) was also added to the BAP mediums at a concentration of 0.5 mg L-1. Shoot formation, shoot lengths, the number of shoots longer and shorter than 1 cm, and regeneration of new shoots after subcultures were determined. According to the results, MS mediums containing 3.0 and 4.0 mg L-1 BAP could be good starting mediums for regenerating new lisianthus shoots from leaf explants. These treatments got the highest values both in shoot formation and the number of shoots longer than 1 cm. It has been determined that 3.0 mg L-1 BAP alone can be used for both organogenesis from leaf explants and shoot proliferation in single node culture. In vitro shoots of the lisianthus species were easily rooted and both PGR-free MS or ½ MS mediums. Lisianthus shoots propagated under in vitro conditions can be rooted under ex vitro conditions both in the float hydroculture and in the soil mixture. The acclimatization stage was optimized also successfully.
Information Seeking Behaviour of Prisoners in Okekura Maximum Security Prison, Ilorin, Kwara State, Nigeria
Authors: Oyedokun Tunde Toyese , Otonekwu Florence Onyeisi , Ambali Zainab , Adesina Olabisi
Published: September 2023

Prisoners are socially isolated people with limited access to friends, family, and information. Incidentally, prisons are meant to serve as a form of punishment for crimes. However, the purpose of a prison term is to assist the offender in making amends for their wrongdoing and preparing them for reintegration into society as decent human beings. Okekura, a maximum-security prison in Nigeria, is located in Ilorin, the state capital of Kwara, and inmates in its custody have a wide range of information requests, many of which are delicate and generally unmet. Interpersonal information sources are mostly used due to a combination of inherent bias and limited access to other information sources. When a person seeks and uses information for a variety of purposes, they are engaging in information seeking. It covers people's information demands, wants, and uses, as well as the impacts that information has on their daily lives. This analysis focuses on the information requirements, sources, and challenges those inmates at the maximum prison in Ilorin encountered when attempting to locate and utilize information.

STABILIZATION OF THE FIELD WATER-OIL EMULSION BY ELECTROHYDRAULIC IMPACT WITH A 15-FOLD DECREASE IN VISCOSITY
Authors: Lykov V.V. , Makhmudova L.Sh. , Laieva K.Sh.
Published: September 2023

For the first time, the inverse, no less urgent, task of influencing the field oil-water emulsion (OWE) has been solved — not to destroy the OWE and decompose it into oil and water (a direct task), but to create a stable emulsion, while its viscosity should be significantlyreduced. The electrohydraulic effect was used to influence on OWE — the formation of a shock wave as a result of a pulsed plasma electrohydraulic discharge (PAED) in a liquid (electrohydraulic shock — E-shock). The study was carried out on crude water-oil emulsions of the Taylakovsky field of the Slavneft-Megionneftegas-Gazpromneft. The field OWE contains 80 % water and is located near the point of inversion «oil-water» to «water-oil», as a result of which its viscosity reaches critical values up to 50 Pa∙s, which does not allow it to be transported through pipelines without the use of expensive inhibitors. The effect of E-shock on the OWE led to multiple crushing of large liquid droplets and the formation of a stable, non-delaminating oil-water emulsion for a long time. At the same time, there was a decrease in the viscosity of the OWE by 15-20 times. As a result of the effect of E-shock on the OWE, the type of liquid has changed. From a non-Newtonian thixotropic fluid, the OWE was transformed into a Newtonian fluid with viscosity independent of the measurement time. It is shown that, in contrast to the generally accepted ideas, the viscosity of the OWE decreases, but does not increase with a decrease in the diameter of the droplets in the emulsion. The obtained practical results make it possible to transport OWE through pipelines without the use of expensive inhibitors and reduce the cost of its transportation by 2.5–5 times. We also studied the effect of E-shock on partially dehydrated up to 20% of the water content of the OWE of the Tailakovsky field. As a result of exposure, an emulsion stable for a period of more than 3 months with a decrease in viscosity by 2–3 times was obtained. The type of liquid of the oil-water emulsion has changed after the E-shock exposure — from a non-Newtonian liquid, the OWE becomes a Newtonian liquid.
High-Tech and Criminal Challenges

Published: September 2023

Achievements in high technologies are improving the standard of living and the quality of live, open up new opportunities for social activities, including business, and help counteract crimes. However, their downside is the emergence of new criminal threats, for example, the dependence of modern society on the global information network creates an opportunity for its criminal abuse. Such technologies could be used to commit traditional crimes (for example, property theft), or could lead to new forms of offences. A wider use of electronic document workflow results in a growing number of falsifications of «electronic proofs». The authors propose a more active criminal law reaction to cybercrimes, AIrelated crimes, and crimes in the sphere of biotechnologies. In this article, they show the necessity of looking for new, more effective forms of counteracting these crimes, including the develeopment of digital criminalistics. The authors analyze normative legal acts, research and journalistic articles dedicated to the use of assisted reproductive technologies in Russia and abroad. It is stressed that the criminalistic support of protecting assisted human reproduction against various forms of abuse, including criminal ones, should be researched in complex with moral and family values, reproductive human rights, development of genetic engineering. A multidisciplinary approach, which incorporates criminalistics, made it possible to state that current Russian legislation regulating legal relations in the sphere under consideration needs improvement. This situation opens up opportunities for abuse, including such crimes as falsification, fraud, corruption. The COVID pandemic worsened the situation as much graver crimes, including human trafficking, were revealed. The authors identified the possible directions of using criminalistics in the system of measures for ensuring the safety and protection of human rights in the sphere of assisted human reproduction.
First records of Brephidium exilis (Boisduval) (Lepidoptera: Lycaenidae) from south-western part of the Arabian Peninsula suggests possible further dispersal into North Africa

Published: September 2023

During surveys in February and September 2022 focused on the butterfly fauna of the mountainous southwestern part of the Kingdom of Saudi Arabia, we unexpectedly discovered the alien species Western Pygmy Blue (Brephidium exilis) at two locations. These are the first records of this species in the southwestern part of the Arabian Peninsula, where its main range was previously restricted to the Arabian Gulf region. Adults were observed at atypical elevations and in forested areas. These findings indicate greater ecological plasticity of the species and possibly suggest its further dispersal into North Africa and the Mediterranean region. While long distance dispersal from Arabian gulf region seems the most reasonable origin, human introduction via transfer of host plants could not be excluded.

The racial composition of assistant coaches, however, was nearly 50% Black and 50% White. While the head coach of a Power-5 football team serves as the leader of the program, the 10 assistant coaches permitted by the NCAA oversee a variety of critical roles; the most valuable of which is recruiting. This study extends previous work by examining the racial composition of Power-5 football coaching staffs and recruiting responsibilities through the lens of racial tasking. An analysis of Power-5 football recruiting classes from 2019 and 2020 illustrates that assistant coaches are tasked with recruiting recruits racially similar to themselves 58% of the time. Furthermore, Black assistant coaches are disproportionately tasked with recruiting Black recruits and higher rated recruits (i.e., five- and four-star) compared to their White counterparts. We contend such racialized responsibilities and expectations may affect opportunities for advancement among Black assistant coaches.

A dinuclear zinc complex [Zn2L2] (1), and four mononuclear zinc complexes [ZnBr2(LH)2] (2), [ZnCl2(LH)2] (3), [Zn(LH)2(NCS)2] (4) and [ZnI(CH3OH)L] (5), have been prepared from the Schiff base 5-bromo-2-((cyclohexylimino) methyl)phenol (HL) by microwave irradiation method. All the zinc complexes were characterized by CHN elemental analyses, infrared and electronic spectra. Structures of the complexes were further studied by single crystal X-ray determination, which reveals that all the zinc atoms in the complexes are in tetrahedral geometry. The halide and pseudohalide anions are preferred co-ligands in the preparation of such complexes with binary ligands. The biological activity of the complexes on the bacterial strains Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli was evaluated. The complexes bearing halide and pseudohalide ligands show effective activities on the bacteria strains.

Handling and Sampling Medium-Large Mammals - ISL Peru v1
Authors: Tirapelle Cristian
Published: September 2023

Program Timing Trap placement and habituation occurs toward the end of the rainy season (March - May). Sample collection occurs annually during the rainforest dry season (June - August). Sample analyses is ongoing between September and April each year. Team Composition This protocol is intended to be carried out by a team of 4 individuals, including at least 2 trained personnel. Roles include: (1) designated handler; (2) chemical restraint operator; (3) sampling assistant; (4) data recorder. Program Overview Tomahawk live traps are set up at multiple locations encompassing major habitat types surrounding the field station (terra firme, flood plain, swamp, bamboo, successional forest, primary forest, edge forest, etc). Locations are selected based on prior knowledge from the area, camera trap footage, or following standard line transect methodology. Traps may be placed but not activated for a long period of time, until there is evidence that capture of the target animal is likely and predictable.We intend for 10-20 captures each season. Capture Overview When a tomahawk trap is baited and activated it is also fitted with a real-time, remote alert system -> medium- to large-size mammals will be chemically restrained with injectable anesthetic agents (10-15 min) -> upon induction, the animal is extracted from the trap for safe processing of morphometric measurements, photographs, nonlethal tissue collection (skin biopsy, fur/nail, blood, mucosal swabs), and placement of microchips or ID tags (20 min) -> an antagonist is administered and the animal is transferred into a covered holding cage, with 3-minute checks for breathing and movement until fully alert (on average ~ 10 - 15 minutes) -> once fully alert, animals are released at the site of capture. Capture (Additional Details) Animals are diverse in their behaviors, attraction to bait, and use of forest habitat. Occasionally, for species where capture with a Tomahawk Trap is not possible, such as sloths and anteaters, a capture attempt with the aid of restraining tools may be performed during a chance encounter. In this case, animal processing will be the same as described in this protocol.
Handling and Sampling Bats - ISL Peru v1

Published: September 2023

Program Timing: Sample collection occurs annually during the rainforest dry season (June - August). Sample analyses occur between September and April. Program Overview: Bat mist nets are set up at multiple locations encompassing major habitat types surrounding the field station (terra firme, flood plain, swamp, bamboo, successional forest, primary forest, edge forest, etc). Mist netting occurs over 3-4 consecutive days at each location throughout the sample collection period. Dependent on resource availability and personnel, we strive for an annual sample size of 200 - 300 bats. Team Composition This protocol is intended to be carried out by a team of 3 individuals, including at least 2 trained personnel. Roles include (1) designated bat handler (2) sampling assistant (3) data recorder. Modification of team composition should be made according to the anticipated number of captures. Capture Overview: Mist nets are installed a day prior or several hours ahead of an intended capture event -> nets are opened between 17:00 and 22:00 (generally), and captures occur spontaneously throughout (~ 5 - 20 animals/event) -> animals are extracted from net (1-2 minutes) -> transferred into a light and breathable cloth bag and kept in order-of-capture in a nearby tent until processing (0 - 30 minutes) -> one-by-one animals are processed for morphometric measurement, photographs, marking (optional) and nonlethal tissue collection (~10 minutes) -> animals are immediately released at the site of capture once processing is complete, but away from mist nets.

The role of algorithms in software or programming is so important that you need to understand the basic concepts behind them. In most of our daily life, we often face problems that need to be solved by entering the data sorting process. A lot of programming logic has been created, both in the general case and in the special case. In this study, the authors carried out the sorting process with two methods, namely bubble sort and tim sort. Sorting application is built using C++ program. Algorithms are needed in order to be able to solve a problem more effectively and efficiently in a shorter time using only a few resources. The preparation of this research uses data collection methods that aim to obtain the necessary data so that it can be extracted to be used as information. It is hoped that from this information it can be seen that the comparison of the bubble sort algorithm with the tim sort is getting better in the data sorting process, if the number of inputted data is greater than n.

Applications of Biometrics technology are extremely popular today, ranging from access control to automation. Fingerprint is the oldest and the most widely used biometrics technology. However, its key features are externally exposed which make it tend to be easily forged. This study investigates the possibility of electrocardiogram (ECG) signal as an alternative modality for biometrics systems. Besides that, the study is conducted using the ECG database under arrhythmia conditions to accommodate the real-world application since arrhythmia exists in large-scale world populations. In this study, a total of 8,972 datasets from 47 subjects were modeled using a machine learning technique (i.e., one-dimensional convolution neural network or 1-D CNN). The results showed that the accuracy (F1-score) of 92% and 0.25 of loss was achieved. Furthermore, we prove that the proposed model is a good fitting based on the visualization plot of the train-test. These findings show that the proposed model is reasonable enough for an ECG-based biometrics system though it's not the best in the literature.

The development of technology is now very rapid. One of them is the use of the internet of things in various fields. One of the applications of technology that is developing in the world including in Indonesia is in agriculture. In this field, there is a model of how to grow plants verticulturally that utilizes limited land. In agriculture, the verticulture cropping technique known as vertical cropping requires optimal soil moisture through proper watering. So an automatic monitoring process is needed to measure soil moisture, air humidity to plant temperature. In this study focused on optimizing the automatic monitoring system using the blynk application compared to ordinary monitoring. This research also encourages further exploration of the use of micro controllers and internet of things technology in agriculture.
