Authors: Ramon Sanchez-Rosario , Karla Pratt , Mónica Aquino , Pedro Vega , Sergio H Sanchez , Doris Peña-Calderon
Published: April 2024

The evolution of the cigarette industry took us from traditional to electronic cigarettes (e-cigs). These are electronic devices that produce nicotine-containing aerosols by heating a liquid (e-liquid) that contains the drug as well as other numerous compounds. Although designed to decrease the harmful effects of traditional cigarettes, little is known about the long-term health incidence of e-cigarettes. The chemical composition of e-liquids varies depending on their manufacturer, country of origin, and batches. Fundamentally, e-liquids contain glycerol, propylene glycol, water, and nicotine. However, a concerning number of toxic substances including heavy metals, nonmetals, pesticides, polycyclic aromatic hydrocarbons, volatile organic compounds, and many other molecules have been identified in them. A wide number of analytical techniques have been employed in the identification and quantitation of these chemicals in liquids as well as aerosols. This review will discuss the numerous chemical substances associated with the use of e-cigarettes, including the potential impact of these on human health. Additionally, this work will address the available analytical tools as well as promising technologies that can contribute to future toxicological characterization efforts. This review also covers some of the global regulatory policies including their challenges and loopholes.
Accounting for behavioral deficits associated with damage in terms of cortical and subcortical information processes
Authors: L Andrew Coward
Published: April 2024

The way information about neurons in the brain is organized is critical to understanding how anatomical structures support cognition and why damage to specific anatomical structures results in specific deficits. Theoretical considerations indicate that the architecture of the brain has been constrained into some specific forms, and these forms make it possible to organize neuroscience information to achieve understanding. Different anatomical structures specialize in different information processes, where the information processes performed by one structure will support many different types of cognitive processes. However, all information processes in the brain are of two general types, condition definition/detection, and behavioral recommendation definition/integration. Motor and cognitive processes are carried out by combinations of processes of these two types. Cortical structures specialize in condition definition/detection processes and subcortical structures specialize in behavioral recommendation definition/integration processes. Local circuits within the cortex-hippocampus-thalamus-basal ganglia-cerebellum system perform different detailed information processes of these types. Brain damage to a specific structure results in loss of the information processes performed by that structure. The different deficits resulting from Parkinson’s disease, Huntingdon’s disease, Hemiballism, Tourette’s syndrome, damage to the hippocampal system, and strokes affecting the cortex, thalamus, or cerebellum can be understood in terms of the loss of specific information processes performed by different brain structures.

Authors: García-Ceberino Juan M. , Gamero María G. , Feu Sebastián , Ibáñez Sergio J.
Published: April 2024

Students' perceived competence determines the adherence or abandonment of sports practice. The purposes of the study were: i) to know the existing association between the perception of competence with the students’ intention to be physically active, after learning football in the Physical Education; and ii) to compare which method (Tactical Games Approach or Direct Instruction) cause that the students feel more competent and greater interest for continuing to practice this sport. The effect exerted by gender and football experience was also analysed. A total of 41 students participated in the study, distributed in two class-groups. Each class-group followed a different program: fifth level, group A (tactical program, n = 20) and fifth level, group B (technical program, n = 21). The competence psychological need was calculated through the Basic Psychological Needs in Exercise Scale and sport adherence using the Intentionally Measure to be Physically Active Questionnaire. Spearman’ correlation shown that the more competence in football, the degree of sport adherence is greater. The Mann-Whitney’s U test indicated that there are no statistical differences according to the teaching method; however, the tactical program students shown a higher perceived competence. The gender and football experience of the students influenced the perceived competence and adherence to sports. This incidence was calculated using ANCOVA. For this reason, it is necessary to use comprehensive methods in the context of Physical Education for the development of competence and sport adherence to football, emphasizing of the female and the inexperienced students.
Percepción de salud, de soledad, de felicidad e imagen corporal según el tipo de desayuno durante el confinamiento a causa de la Covid-19
Authors: Carrillo López Pedro José
Published: April 2024

The aim was to determine the relationship between the perception of health, loneliness, happiness and body image according to the type of breakfast during the state of alarm decreed by the COVID-19 in primary schoolchildren. For this purpose, a descriptive cross-sectional study was designed with a sample of 116 Spanish schoolchildren. Perceptions of health, loneliness, happiness and body image were assessed using four items from the Health Behavior in School-aged Children questionnaire. The items referring to breakfast were extracted from the Mediterranean Diet Quality Index in children and adolescents questionnaire. After inferential analysis, it was observed that eating a cereal or derivative for breakfast was associated with a higher perception of health (OR = 1.45; p = 0.021), happiness (OR = 1.57; p = 0.002), body image (OR = 1.70; p = 0.006), and lower perception of loneliness (OR = 1.74; p = 0.002). This association was maintained after adjustment for body image with the exception of health perception (OR = 1.53, p = 0.156). In conclusion, eating a cereal or derivative for breakfast may be related to a higher perception of health, happiness, body image, and lower perception of loneliness in primary school children.
Efecto de la masa del balón en la cinemática del lanzamiento en balonmano
Authors: Gutiérrez-Dávila Marcos , Sanchez-Sanchez Francisco , Gutiérrez-Castro Alberto , Gutiérrez Cruz Carmen
Published: April 2024

The aim of this study was to discriminate the effect of five increases of 15% in the mass of the ball on the most significant kinematic variables that determine the throwing performance. The sample was comprised of twelve male players specializing in front-line throws and belonging to the Spanish Asobal Handball League. Every throw was recorded by two video cameras temporally synchronized at 250 Hz, which allowed us to obtain the spatial coordinates of a model made up of five body markers and the geometric center of the ball. From these coordinates, the components of the positions and linear velocity of the ball were determined, in addiction, the angular positions and velocities of vertical rotation of the upper trunk, shoulder flexion, external / internal rotation of the shoulder, and flexion / extension of the elbow were also obtained. The results indicate that the velocity of the ball decreases with the increase in the mass of the ball and the angular velocity of internal rotation of the shoulder is the most affected factor, followed by the extension of the elbow. The throwing time increases when the mass of the ball increases due to the longer backward movement time of the ball. It is estimated that a 15% increase in the ball mass has no effect on the kinematics of the throw.

Padel has had exponential growth in recent decades and is practiced by players of different ages and competitive levels, however, the characteristics of the rackets they use have never been analyzed. Thus, the objective of the study was to analyze the characteristics of the rackets used by men´s amateur padel players according to their experience, the number of practice hours per week, their usual side of the court and their laterality. A total of 873 men´s amateur padel players ( age: 29.99 years;  weight: 78.71 kg;  height: 177.51 cm) participated voluntarily, completing an ad-hoc questionnaire. The results indicate that amateur men´s padel players usually use rackets made of carbon fiber (73.2%), with a weight between 351 and 370 grams (60%). In addition, the experience of the players and the number of playing hours per week are associated with the number of over grips and the composition of the racket. The playing side of the men´s amateur padel players is associated with the shape of the racket and the dominant hand is associated with the composition of the racket. These findings are very new as they can help men´s amateur padel players to choose their rackets.

Published: April 2024

In recent decades, the teaching profession, as a result of changes in the professional space and post-Bologna training processes, has been the target of multiple transformations emerging in the reconfiguration of teachers' professional identities, which is why it is important to provide knowledge about its construction process.The purpose of this review is to understand how the Professional Teacher Identity in Physical Education is built and to identify the elements that contribute to its construction. The review was carried out in the Dialnet databases between 2010 and 2022 using the as keywords: Professional Identity and Physical Education, in Spanish or Portuguese in peer-review academic journals. 18 research papers were selected among 54 identified that where submitted to a thematic analysis. Three themes were identified: i) professional teaching identity construction (9 studies), ii) elements that contributed to teacher professional identity (3 studies), iii) construction and elements related to teacher professional identity (6 studies). The findings suggest that teacher professional identity is building from personal, social and professional interactions within a dynamic and progressive process during initial training and professional practices influenced by previous experiences.

Published: April 2024

The engagement motor time is one of the most studied variables in the Physical Education (PE) subject. Its importance is increasing, especially today due to the levels of physical inactivity and sedentary lifestyle of children and adolescents. The objective of this research is to know how CLIL is being implemented in PE sessions, according to the CESEFA questionnaire, and how the introduction of a new language (L2) impacts on the TCM of the subject. To this end, 30 PE sessions were recorded with different teachers, both bilingual (n = 11) and monolingual (n = 19) to later compare the information obtained using descriptive and contrast statistics (ANOVA). The results show a significant reduction of 11.4% in TCM of the bilingual groups compared to the monolingual groups. Furthermore, the implementation of CLIL in PE sessions should be improved considerably since it presents relatively low values. Finally, it is necessary to highlight the importance of specific methodological training in bilingual teachers to be able to develop their teaching work within quality criterio.

Published: April 2024

Handball game passed by normative changes in 2016, and some influenced the use of the additional court player (ACP), both related to organizational, strategic, tactical, and technical issues. This study aimed to analyze, from the speeches of Brazilian handball coaches, the influence of ACP on handball training process after 2016. Seven coaches were interviewed, who have already been classified among the top four clubs in the Brazilian national men and women leagues and/or who participated in the technical staff of the Brazilian national teams (men and/or women). Data were thematically analyzed. The 2016 normative change raised new handball tactical landscapes, as the coaches developed changings on offensive and defensive actions using and playing against ACP.

Authors: Sánchez Sánchez Javier , Tocino Pablo , Ramirez-Campillo Rodrigo , Rodriguez-Fernandez Alejandro
Published: April 2024

The aim was to analyze the effect of two activation protocols based on exercises with bodyweight and elastic bands on the improvement of muscle power. Ten male university students of Physical Activity and Sports Sciences (age: 23.1±1.5 years) randomly completed with 48 hours of recovery between sessions, a control situation without warm-up (CON) and a warm-up protocol based in bodyweight (ACA) and elastic band (ACE) exercises. After each protocol, power tests were performed in the squat  and bench press with submaximal load (i.e.,  ~1,00m/s and ~0,79m/s, respectively) and vertical jumps without (SJ) and with countermovement (CMJ), together with a horizontal jump (SHB). Compared to CON, no improvements in strength were observed following ACA and ACE. However, significant improvements (p < 0.05) were obtained in SJ, CMJ, and SHB after ACE, while ACA only improved (p < 0.05) SJ and CMJ. Protocols that use exercises with bodyweight or elastic bands can improve performance in actions without load, but do not improve power at submaximal loads.
Bayesian inference for the inverse Weibull distribution based on symmetric and asymmetric balanced loss functions with application
Authors: Hasaballah Mustafa Mohamed , A. Tashkandy Yusra , Balogun Oluwafemi Samsin , Bakr M. E.
Published: April 2024

In this study, the unified hybrid censored approach is employed to estimate the parameters of the inverse Weibull distribution, as well as the survival and hazard rate functions. Parameter estimates are obtained using both Bayesian and Maximum Likelihood approaches, with Bayesian estimates acquired through Lindley's approximation method using three distinct balanced loss functions. These encompass both symmetric and asymmetric balanced loss functions, specifically the balanced squared error (BSE) loss function, the balanced linear exponential (BLINEX) loss function, and the balanced general entropy (BGE) loss function. We conduct a simulation study to compare the effectiveness of various estimators, and a real-world data analysis is presented to illustrate practical implementation. Ultimately, our findings indicate that Bayesian parameter estimates consistently outperform their Maximum Likelihood counterparts across all methods.

Published: April 2024

Osteogenesis imperfecta (OI) is a hereditary bone condition characterised by fragile bones to be more susceptible to fracture. We reported a rare case of a 6-year-old girl with OI Type V and hyperplastic callus formation. She presented with recurrent fractures since birth with no family history of a similar condition. Clinically, her height and weight were lower than the 5th percentile for her age. She had deformities with limitation of movement of elbows, kyphoscoliosis, a more extensive right thigh, and anterior bowing of both legs. Radiographic examination revealed interosseous membrane of forearm ossification, dislocation of the right radial head and hyper-callosity of both femurs during fracture healing. She was treated with intravenous pamidronate and had posterior instrumentation and fusion for scoliosis and intramedullary rodding for her femur fracture. On a recent follow-up at the age of 16 years, she was ambulating well with no progression of the spinal deformity.
The Power of the Powerless: Constructions of Self‐Employment in Czechia
Authors: Lukeš Rybanská Ivana , Čada Karel
Published: April 2024

This article examines the construction of self‐employment in public policy debates, focusing on how political actors define self‐employment and on the moral implications of these categorisations. Employing critical discourse analysis and the social construction of a target population, the authors examine verbatim transcripts of parliamentary debates in the Czech parliament between 2021 and 2023. These debates reveal how legislators perceive the value of self‐employment as a part of the economy. The study explores the underpinnings of such public policy debates, as well as the moral consequences of categorising self‐employment. We argue that by foregrounding some morally loaded argumentations and, in particular, discursive constructions, politicians (as both discursive and policy actors) make some parts of the experience of self‐employment invisible and neglected by policy; as a result, this contributes to the precarity of the self‐employed.
Handbook, Standard, Room: The Prescription of Residential Room Types in Sweden Between 1942 and 2023
Authors: Movilla Vega Daniel , Juan Liñán Lluis
Published: April 2024

Norms and handbooks have played a key role in the design of residential rooms in Sweden since the 1940s. Ever since, changes in housing policies have led to varying definitions and regulations of residential rooms, allowing their existence, defining their configuration, and framing their performance. And yet, none of these rooms has been built; they are prescribed room types that belong in the pages of handbooks that validate the framework in which housing design can operate. What are these prescribed room types? What do they look like? Who and what do they include? Have they changed over time? In response to these questions, this article follows the evolution of a set of residential room types in the design handbooks that have accompanied housing policy bills in Sweden from 1942 to 2023. These manuals are not the law itself but operate as an interface for professionals and designers by reflecting the practical consequences of the norm. Diagrams, dimensions, texts, and references to housing literature vary from handbook to handbook to define the specific traits of each type of room. By studying these traits in relation to key moments of Swedish housing politics, the article reveals the role that norms and standards have played in the establishment of the regulatory regime in which housing design in Sweden operates today.
Application of Correlation Analysis to Determine the Discrepancy Between Indicators for Two Different Samples: Comparison of the Intellectual and Personal Development of Children of Primary School Age, Studied with an Interval of 10 Years

Published: April 2024

Correlation analysis, which is actively used in psychological research to identify the relationship between psychological parameters, loses its meaning when the samples being compared are different. At the same time, studying possible connections of psychological indicators between samples may have some meaning in special cases. Purpose of the work: to show the possibilities and propose a technology for using correlation analysis to determine the agreement of indicators for two different samples using the example of a long-term (retrospective and modern) study of the intellectual and personal characteristics of the development of schoolchildren in the 2nd grade of a general school with an age difference of 10 years. For correlation analysis, we used assessments of intellectual development according to the level of work in the “Beasts in the Circus” method of the “Creative Field” method (Bogoyavlenskaya, 1971) and intelligence according to the “Standard Progressive Matrices” test by J. Raven. To implement the possibility of a full correlation analysis of general indicators of different samples, the work proposed a technique for preliminary linking two different samples of the same size to each other by matching them on one of the common sample variables.
Interdisciplinary Aspects of the Introduction of Virtual Reality Technologies in Court Proceedings

Published: April 2024

Modern law is closely interrelated with the active development of high technologies. Judges, prosecutors, lawyers, as well as other participants of court proceedings are gradually introducing elements of digitalization into their activities. In some countries, neural networks are already being used to help the judge in making a decision in the case under consideration, and also consider court cases in the metaverse. However, any high-tech tools that are easy enough to integrate, for example, into the business sphere, are introduced into law with certain restrictions. They include normative and legal regulation, technological solutions, and digital literacy of the population. However, even all these conditions being provided, the consideration of civil and criminal cases in virtual reality is quite a difficult task. Jurisprudence traditionally remains one of the most conservative institutions, extremely reluctant to introduce high technologies. This paper, taking into account the experience of the courts of Colombia in the consideration of cases in the metaverse, elucidates technical and legal aspects of the introduction of virtual reality technologies in the consideration of civil and criminal cases by Russian courts. The authors analyze the implementation of the principles of legal proceedings, the rights of participants, identity verification and the flow of information.
Significant Aspects of Teaching Legal Negotiations to Law Students in Russia
Authors: Kalmazova N. А. , Vyushkina Е. G.
Published: April 2024

The paper deals with the overview, prioritization and analysis of the elements that are inalienable in legal negotiations and teaching modules of the course on negotiations. An experienced legal negotiating coach keeps in mind a number of vital elements of the course, such as personal ch aracteristics of learners, stylistic patterns and cultural features. The data collected in the research supports the fact that cultural shifts reflected in the statements of negotiators have a direct impact on the negotiation result and often lead to misunderstandings and inability to reach an agreement. For instance, Russian businessmen often unconsciously apply inflexible aggressive integrated strategy of negotiations. Thus, the negotiation course module devoted to cultural awareness and appropriate negotiating strategies development should contain, inter alia, information connected with authentic reactions of negotiators belonging to a particular ethnic group, and this information should be scrutinized and deeply considered. Consequently, it will be useful to apply the priming teaching technique through the comparison and analysis of students’ responsive statements with native speakers’ responsive statements in one and the same simulation which will facilitate mastering successful negotiation skills leading to a package deal beneficial for all parties.

Authors: Bozhendaev Timofey L. , Guseva Natalya B. , Pismennaya Elena V.
Published: April 2024

Lower urinary tract dysfunction occurs in 30%–55.5% of patients with cerebral palsy. The article presents a clinical example of medical rehabilitation of a child with cerebral palsy and dysfunctional urination using the verticalization method and ExoAtlet exoskeleton. Description of observation. A 15-year-old boy had urinary disorders in the form of urine leakage after urination, incomplete emptying of the bladder, episodes of enuresis, and frequent urination while sitting. The gait was unsteady and aided with crutches supported by the elbow. Examinations included uroflowmetry and electromyography. The results indicated a decrease in contractility and impaired evacuation function of the detrusor. In total, 15 rehabilitation sessions were performed using the ExoAtlet exoskeleton, after which the patient gained an independent gait supported by a cane, and the child was taught to urinate in a standing position. A repeat urological examination revealed a positive change in urination parameters with partial relief of pollakiuria and complete relief of the residual bladder volume. Verticalization and activation of striated muscles, obtained following the use of an exoskeleton in a child with cerebral palsy and dysfunctional urination, in combination with restored posture, helped normalize lower urinary tract function.

The use of robots in pancreatic surgery offers several advantages as an adjunct to laparoscopic surgery, including increased maneuverability of robotic instruments and three-dimensional (3D) visualization. To our knowledge, only two cases of robot-assisted distal pancreatectomy with spleen preservation in children have been reported worldwide. In this study, the patient was an 11-year-old boy who was admitted to a children’s hospital with complaints of recurrent upper abdominal pain. He was diagnosed with pancreatic tumor based on ultrasound findings. It was confirmed by magnetic resonance imaging, which revealed a well-defined heterogeneous formation at the border of the body and tail of the pancreas, measuring 2.28 × 2.73 × 2.62 cm with compression of the Wirsung duct. The surgical intervention was performed using a surgical robot VERSIUS (CMR, (UK). Splenic vessels were mobilized carefully, a tourniquet was placed around the body of the pancreas, and it was intersected using a stapler at the border of healthy tissue. The surgical intervention took 340 min, including robot installation time (docking time) of 15 min and a main console time of 325 min. No serious intraoperative complications, such as bleeding or damage to the vascular structures adjacent to the pancreas (branches of the celiac trunk and portal vein), were noted. Histological examination of the tumor confirmed the diagnosis of a solid pseudopapillary tumor. After surgery, the patient’s condition was stable. Recovery proceeded without complications. Magnetic resonance imaging of the abdominal cavity, which was performed 6 months after surgery, revealed no signs of disease recurrence. Robot-assisted surgery is an acceptable alternative to laparoscopic and open surgery for patients with solid pseudopapillary pancreatic tumors because robots offer additional connections, enable closure in improved 3D imaging, increase dexterity when handling instruments, and eliminate of hand tremors.
Metaverse: a new reality in surgery. Review
Authors: Kozlov Yury A.
Published: April 2024

The metaverse is a relatively new concept in technological advancement. It is a three-dimensional immersive environment including real and virtual world elements, in which various digital agents, more precisely, avatars, interact with each other and various activities (educational, cultural, and financial) can be carried out. It is an emerging controversial concept without precise definition and will likely continue to evolve as technology improves. Works of literature from 2020 to 2023, posted in the PubMed and Web of Science databases, were extracted using the following keywords: “metaverse”, “education”, “digital therapy”, “interdisciplinary consultation”, “medical Internet of things”, “virtual reality”, “superimposed reality”, “extended reality”, “mixed reality”, “lifelogging”, “mirror world”, “digital twins”, and “surgery”. In the PubMed search using the original terms, no publications were extracted in 2020, 9 in 2021, 161 in 2022, and 246 in 2023. In the healthcare context, metaverse technology refers to the use of virtual reality and interactive and other immersive technologies, such as augmented reality, to create simulated environments intended for training, education, and clinical applications. Various aspects of medicine such as digital therapeutics, multidisciplinary team discussions, medical Internet of things, surgical simulations, conferences and meetings, research programs, etc., are being explored. Depending on the requirements, the metaverse provides a versatile platform that can be modeled accordingly, providing a flexible tool for medical development. In this review, we discussed in detail the possible applications of the metaverse in surgery. All scoping rubrics are based on the sparse evidence in the scientific literature and are adequately evaluated to provide compelling evidence on the utility of the metaverse in the future of medicine.

The Right of the Child to Respect the Image and the Phenomenon of Sharenting
Authors: Reps Magdalena
Published: April 2024

Technological progress has contributed to the development of social media. As a result, increasing interest in contacts between people via instant messengers, but also in the publication of various content. Today, most of the society has profiles on social networking sites, where they publish both their own photos and the image of their children. When parents decide to disseminate photos and recordings with their children, they do not realize that they are violating their right to the protection of privacy and image. Civil law protection of minors against sharenting is one of the basic tasks of the state authority. It is the duty of public authorities to protect individuals who cannot independently take action against persons who violate their right to privacy. The author decided to choose this topic because today many parents sharent and do not respect the right of minor children to privacy. The main purpose of the article is to analyze the legal regulations regarding the civil law protection of children against the phenomenon of sharenting. The work uses the dogmatic and legal method and the analysis of judicial decisions.
Protecting the Interests of a Minor in Medical Law
Authors: Telak Marta Sylwia
Published: April 2024

The purpose of this article is to discuss issues related to the protection of the interests of a minor in the procedure of medical law. Using a dogmatic-legal research method, the case law of the Supreme Court, the provisions of the Family and Guardianship Code and the provisions of the Act of November 6, 2008, on Patients’ Rights and the Ombudsman for Patients’ Rights, were analysed. According to the jurisprudential line, “one of the manifestations of an individual’s autonomy and freedom of choice is the right to decide for oneself, including the choice of treatment method. A reflection of this right is the institution of consent to the performance of a medical procedure, which is one of the prerequisites for the legality of therapeutic activities”. A person’s health and life are personal goods under the special protection of civil law. Equally protected is the personal good of autonomy of decision-making, which is the basis for the “disposal” of one’s own body and, consequently, health and life. The situation of minor patients, who are deprived of the right to decide on the health services provided to them, as well as minors, who have no influence on the decision on the choice of treatment, should also be considered. How are their interests protected? What if the minor and his parents have different opinions about the treatment, or if they do not consent to his treatment at all? How far can the legislature interfere in the exercise of parental authority and how is the minor patient protected? Can the guardianship court make decisions concerning life or health? The issues raised are extremely interesting not only legally, but also ethically and socially, for as a rule it is the parent who decides what is good for their child. It happens, however, that his decisions may contradict both the protected good and the principles of social coexistence themselves harm the interests of the minor.

Authors: Jankowska Karolina Agnieszka
Published: April 2024

Statutory representation is one of the institutionalized forms of party representation in civil proceeding. In addition, this institution is important from the point of view of children's rights protection due to the fact that it allows their parents, guardians or curators to take procedural actions on their behalf. The aim of this article is to present statutory representation as one of the forms of minors’ interests protection in civil proceeding. For this purpose it uses the law-dogmatic method to analyse the regulations contained in the Law of November 17, 1964. - Code of Civil Procedure, the Law of April 23, 1964. - Civil Code and the Law of February 25, 1964. - Family and Guardianship Code. The article shows the judicial and procedural capacity of a minor, the subject and object scope of statutory representation, as well as the most significant actions that a statutory representative can take to protect minor’s interests in civil proceedings.

Published: April 2024

O Censo Demográfico compõe um conjunto de pesquisa das mais relevantes para a leitura do Brasil, permitindo-nos analisar as principais transformações socioeconômicas e espaciais do território brasileiro. Em suas diversas escalas, possibilita identificar processos e tendências que contrastam com dinâmicas territoriais pretéritas, mudanças populacionais e demandas sociais emergentes. O objetivo deste texto é analisar essas transformações no estado de Rondônia, apresentando como eixo analítico a expansão da rede urbana e sua dinâmica populacional. Para isso, a metodologia adotada combinou a revisão de pesquisas regionais com análises estatístico-cartográficas. Os resultados indicam dois processos: i) a formação de um eixo urbano e recentralização populacional ao longo da rodovia BR-364, simultaneamente, ii) à dispersão populacional em pequenos e intermediários municípios. De um estado receptor de população, Rondônia passa a um estágio de pouco crescimento demográfico, com frentes de deslocamento populacional para novas fronteiras agropecuárias na Amazônica Ocidental.

Los coeficientes intrínsecos y extrínsecos de dispersión y absorción de ocho muestras de cristales líquidos dispersos en polímero no absorbedoras de luz, con dos diferentes tamaños del área activa y con cuatro diferentes espesores de la capa interna active, en sus estados de apariencia óptica translucidos apagados y transparentes encendidos –sin y con voltaje eléctrico aplicado respectivamente– fueron satisfactoriamente determinados siguiendo el mismo procedimiento descrito en trabajos anteriores con un dispositivo de partículas suspendidas –una muestra de ventana inteligente absorbedora de luz– y con otra muestra de ventana inteligente de cristales líquidos dispersos en polímero. Este procedimiento, basado en los modelos de transferencia radiativa de dos flujos y de cuatro flujos, considera el ángulo crítico de reflectancia interna total para determinar la reflectancia difusa interna de interface, y utiliza la misma ecuación propuesta previamente para el parámetro de camino promedio, basada en las intensidades difusas y totales de los haces de luz hacia adelante y hacia atrás, para resolver el modelo de cuatro flujos a fin de determinar los coeficientes intrínsecos. La apariencia óptica simulada resultó ser un estado apagado translucido blanco lechoso y un estado encendido transparente incoloro que llega a ser más transparente para las muestras de cristales líquidos dispersos en polímero con espesores más finos, requiriendo mayor voltaje aplicado para los estados ópticos encendidos transparente de las muestras caracterizadas de cristales líquidos dispersos en polímero.

In this study, we explored various aspects of Oecophylla smaragdina, a potential biocontrol agent, evolution by examining its morphometric characteristics. We employed an intensive All-out search method (AOSM) to gather specimens from multiple locations in Vadakku Karaseri, Tamil Nadu. Our analysis involved measuring 16 morphological traits and indices, including Total Length, Head Width, Head Length, Eye Length and more, using specimens from five colonies in each locality. By calculating various morphometric indices, we assessed specific features and conducted a Principal Component Analysis (PCA) to determine the significance of head-related variables, antennae, and body size in shaping morphometric variation. Our study also revealed positive and negative associations between different morphometric variables, as highlighted by Pearson correlation coefficients. Furthermore, we used a Scanning Electron Microscope to examine the ultrastructure of the abdomen, revealing distinct features such as a one-jointed pedicel and modifications of the poison gland and stings. This comprehensive research provides valuable insights into O. smaragdina morphometric characteristics, enhancing our understanding of its variability and potential adaptations in various habitats.

Metal-Assisted Chemical Etching method (MACE) has emerged as an effective tool to fabricate silicon nanostructures. This technique requires a catalytic mask that is commonly composed of a metal. In the present work, the role of Silver nanoparticles (AgNPs) in the etching mechanism of Porous Silicon (PS) is investigated by studying the effect of AgNP coverage on the surface porosity and the different properties of PS. XRD spectra consist of the two peaks corresponding to silicon and AgNPs respectively and the peak intensity of Ag decreased with an increase in etching time which indicates that as the etching time increases the dissolution of silver metal also increases. Thus, the pore depth depends on the dissolution of AgNP. The pore depth and porosity are calculated at different etching times by SEM analysis. It is observed that porosity is modifiable with the variation of AgNP coverage which in turn modifies the optical properties of PS. The porosity increased with the increase of etching time and the highest porosity obtained was 78% after 240 minutes. The refractive index of PS decreased with increasing porosity in the visible region. The variation of the refractive index results in the tuning of optical energy gap which is more essential in increasing the efficiency of solar cells.
