Environmental project management in the hospitality industry in Russia using the criteria "risk-profitability"
Authors: Kovaltchuk Andrey P. , Miloradov Konstantin A. , Nikolskaya Elena Y. , Gunare-Plekhanov Marina
Published: September 2022

El artículo describe el enfoque propuesto por los autores para analizar la eficacia de los proyectos de introducción de ecotecnologías en hoteles en relación con la relación riesgo-retorno. El valor presente neto (VAN) del proyecto se utiliza como criterio para evaluar la rentabilidad del proyecto de implementación de tecnología verde. La magnitud del riesgo del proyecto es el segundo criterio, que se puede calcular por varios métodos. Aplicando el enfoque propuesto, los autores analizaron la experiencia de implementación de proyectos ambientales por parte de hoteles rusos. Una ilustración del método propuesto es el diagrama de 'riesgo-rendimiento' para la introducción de tecnologías de ahorro de energía en un hotel de 3*. El enfoque combina las ventajas del método de análisis para la eficiencia del proyecto de flujo de caja descontado y las herramientas de análisis de riesgo del proyecto mediante el uso de dos criterios y se puede aplicar para un análisis rápido y visual de proyectos ambientales en el sector hotelero.

En la formación inicial docente, el estudio de la epistemología constituye una pieza fundamental para que los futuros profesores puedan filosofar sobre la realidad de los diversos contextos educativos y se pregunten cómo mejorarla desde los principios que rigen la investigación científica. De este modo, gracias al sustento epistemológico, los estudiantes de pedagogía pueden formarse como docentes investigadores capaces de analizar los cambios sociales propuestos por las múltiples realidades y conocer cómo se construye el conocimiento científico de una especialidad dada. La finalidad de este trabajo, es presentar una reflexión filosófica-epistemológica sobre la imperiosa necesidad de desarrollar el conocimiento epistemológico en la formación inicial del profesorado de matemática e historia, considerando los fundamentos disciplinares, pedagógicos y cognitivos de dichas áreas.
Ciência, religião e escola
Authors: Quintana Gomes Saulo , De Mendonça Figueiroa Silvia Fernanda
Published: September 2022

Interessa ao educador científico contemporâneo compreender as relações entre ciência e religião, particularmente investigando como elas se dão entre seus estudantes e na realidade por eles vivenciada, posto que essa bagagem cultural está presente na sala de aula. Neste sentido, o presente trabalho objetiva identificar e analisar as principais características e tendências de investigações sobre as relações entre ensino de ciências e a religião, a fim de fornecer subsídios atualizados para quem o desejar ou necessitar. Para tanto, uma revisão de referenciais teóricos sobre a relação ciência-religião é apresentada e, em sequência, reúnem-se e analisam-se produções científicas publicadas entre 2004 e 2020 com foco nas relações entre ensino de ciências e a religião. Entre os resultados observados destaca-se que as relações entre religião e ciência não são homogêneas dentro da escola (nem fora dela): diferentes estudantes, bem como diferentes professores, têm diferentes opiniões, atitudes, e visões de mundo sobre o tema. Além disso, os pesquisadores sugerem atuações pedagógicas frente às relações entre religião e ciência: os conhecimentos sobre a história da ciência bem como conhecimentos sobre a história das relações entre a ciência e a religião são relatados como ferramentas importantes e há unanimidade quanto à importância de combater a noção de conflito entre ciência e religião.
Retos de las ciencias sociales ante los nuevos realismos
Authors: Castillo Villapudua Karla
Published: September 2022

Este artículo plantea la posibilidad de efectuar una renovación teórica en las ciencias sociales de corte constructivista a partir del giro realista surgido recientemente en el marco de la filosofía continental contemporánea. Para ello revisamos algunos aspectos básicos de la ontología orientada a objetos de G. Harman, de la teoría del ensamblaje de Manuel De Landa, y del materialismo especulativo de Q. Meillassoux. Nuestra hipótesis de partida sostiene que estas tres teorías poseen un amplio potencial teórico para reactivar el debate en torno al tema de la realidad en el campo de la investigación social, al margen de cualquier subjetivismo, ya sea mediado por el lenguaje o la conciencia. Por último, pensamos y problematizamos los posibles cambios teóricos y metodológicos que podrían presentarse en este ámbito de investigación una vez asumido el giro ontológico realista de los filósofos aquí revisados.
El mundo como imagen
Authors: Gutiérrez Pozo Antonio
Published: September 2022

Este artículo estudia desde una perspectiva filosófica el papel que desempeña en nuestro mundo la imagen entendida en sentido amplio. Estamos en el mundo de la videosfera. Preferimos las imágenes a las cosas. Lo real se ha disuelto en simulacro. La realidad es ahora la imagen de la realidad, espectáculo. Nada hay ya fuera de las pantallas, de modo que el mundo se ha quedado sin misterio. El propio ser humano se ha convertido en homo aestheticus. En esta videocracia, el mundo como imagen es consecuencia de una voluntad de poder que reduce lo real a objeto. La amenaza de desaparición de lo real y del ser humano todavía no se ha consumado.
Body Size Structure and Sex Ratio in a Population of the Common Lizard Zootoca vivipara (Lichtenstein, 1823) from SW Poland
Authors: Jurczyk Kacper , Borczyk Bartosz
Published: September 2022

We present data on the population structure, body size variations and allometric growth patterns for a common lizard (Zootoca vivipara) population from Southwestern Poland. We measured 339 lizards (89 males, 75 females, 63 subadults and 111 juveniles). The sex ratio did not differ
from 1:1; however, we recorded intra-seasonal variations. There was significant sexual size dimorphism (males were smaller in body length), as well as tail length (males had longer tails) and body mass dimorphism (females were heavier). We also found sexual differences in the allometric pattern
of tail growth, i.e. there was an isometry for males but a negative allometry for females.

Authors: Sorokin E. L. , Kolenko O. V. , Fil A. A.
Published: September 2022

Aim. To investigate the incidence and structure of vascular retinal pathologies in women with preeclampsia and its combination with chronic arterial hypertension (AH).

Methods. A total of 231 medical records of women with different pregnancy histories were studied by consecutive sampling. The first experimental group comprised women (n = 47) diagnosed with preeclampsia combined with chronic AH. The second experimental group comprised women (n = 48) with preeclampsia developed during pregnancy. The first comparison group included women with pregnancy-associated gestational AH. The second comparison group included women with edema and proteinuria during pregnancy but without AH. The control group consisted of women (n = 50) with normal pregnancy histories. The postpartum period ranged from 6 to 12 years.

Results. The development of vascular retinal pathologies during the postpartum period occurred in 28 women in the general sample (12%). Retinal vein occlusions predominated in the structure of vascular retinal pathology (19 women, 19 eyes). Proliferative retinopathy was detected in 8 patients (8 eyes). In one case, a central retinal artery occlusion developed.

Conclusions. The incidence of vascular retinal pathologies in the 1st and 2nd experimental groups comprised 21% and 25% respectively, which was statistically significantly higher than that in the control, 1st and 2nd comparison groups (4%, 4%, and 6% respectively, p < 0.01). The revealed significantly higher incidence of vascular retinal pathology in both experimental groups indicates the domineering role of preeclampsia and AH-associated pre-eclampsia in the development of vascular retinal pathologies.
Conjunctival microbiota of newborns: Current state of the problem and clinical perspectives
Authors: Smirnov A. K. , Fedyashev G. A.
Published: September 2022

The species composition of the conjunctival microbiota of newborns and first-year infants informs the selection of an optimal management tactics for the prevention of inflammatory responses. The effectiveness of antimicrobial therapy depends on the availability of susceptibility testing. The most common types of bacteria found in first-year infants include Firmicutes, Proteobacteria, Actinobacteria, Cyanobacteria, and Bacteroidetes. These bacterium types are most sensitive to fluoroquinolones. The bacterial culture of neonates born naturally most frequently contain coagulase-negative staphylococci, Propionibacterium spp, and Corynebacterium spp., while that in neonates born by caesarean section feature coagulasenegative staphylococci, Propionibacterium spp, and Staphylococcus aureus. An examination of infants with neonatal dacryocystitis revealed a high incidence of inflammatory, fungal, and infectious diseases of the genital tract in their mothers. A correlation was established between the bacterial species obtained from conjunctival and cervicovaginal fluid samples. The microflora composition in older infants is characterized by higher complexity compared to that in younger infants. No significant environmental impact is observed in the group of infants under 6 months old. A more complex ocular surface microbiome in childhood is consistent with alterations in the gastrointestinal microbiome. No alterations in the ocular surface microbiome were observed in infants that underwent ophthalmic surgery. The abundance and composition of microflora was found to depend on the geographical location and individual specifics. The conducted research supports the development of a system for monitoring the conjunctival microbiota composition of newborns in obstetric and maternity hospitals.
Turkmen Epos: Origin and Modern Conditions
Authors: Kurbanova Djamilya
Published: September 2022

The epic branch is one of the central directions of the oral musical and poetic heritage of the Turkmens. The carriers of the epic tradition in Turkmenistan are the bagshy-dessanchy, the modern heirs of the ancient art of ozans. The centers of epic storytelling are located in the Dashoguz and Mary regions, they differ significantly from each other in terms of repertoire, genre and performance features. The main genres in the repertoire of bagshy-dessanchy are the monumental cycles of epic tales “Gokut ata” and “Gorogly”, numerous author's and folk dessans, legends with music, as well as musical transcriptions of literary works of Turkmen classical poets. The structure of epic genres is based on the alternation of poetic and prose sections. Poetic lines are sung in the form of songs, and prose is recited in a performing manner characteristic of each school. Songs determine the development of musical dramaturgy in dessans. The performances of the bagshy-dessanchy represent a consistent movement towards the climax, where each stage of the narrative is characterized by a certain type of epic songs.

CONCRETO ARMADO E SUAS PATOLOGIAS
Authors: Messias Matildes Caio
Published: September 2022

This work approaches the most common pathological manifestations found in reinforced concrete structures, with the objective of analyzing them in relation to the causes and addressing possible treatments for them, not dispensing with the consultation of a qualified technical professional. Another objective is to make the reader aware of the seriousness and consequences that can occur due to negligence regarding the maintenance and correction of pathologies in reinforced concrete structures. First, the text brings an approach to what is reinforced concrete, and then it is lectured on the meaning of the word “pathology” and how they can be generated in a reinforced concrete structure. The causes and mechanisms that can cause concrete deterioration are also presented, in order to provide information on how pathologies can be avoided. Finally, a practical case is cited, about a viaduct that collapsed in the city of São Paulo, illustrating the possible consequences of pathological manifestations without proper supervision and treatment.
ESTUDO SOBRE A FORMAÇÃO DE TALENTOS DE LICENCIATURA EM LÍNGUA PORTUGUESA NA CHINA EM UMA PERSPECTIVA DO CONCEITO EDUCACIONAL DE APRENDIZAGEM CENTRADA NO ALUNO
Authors: XUEJIAO SHANG , NAN WU
Published: September 2022

In the context of increasingly frequent cooperation and exchanges at all levels between China and Portuguese-speaking Countries, the country's and society's demand for Portuguese-speaking talents is increasing even more. The training of Portuguese talent meets the new historic opportunities, at the same time, faces a situation that requires reforms and innovation. Classroom teaching highlights the transition from “teaching” to “learning” and encourages teachers to design and carry out student-centered classroom teaching with the aim of helping students build their own knowledge system and improve their learning ability to meet the needs of future development and changes. In the implementation of teaching, we have shifted from emphasizing on improving teachers' teaching ability to focusing on cultivating students' learning ability. In this context, through interviews applied to Portuguese teachers in China, we analyzed the general situation of students of Portuguese in China, and we explored the application of the concept of “Student-Centered Learning” in Portuguese classes as foreign language. Thus, we will come up with suggestions to promote classroom efficiency and student skills in the PLE teaching process.
Quem é o responsável disso?! Fake news e responsabilidade enunciativa em tempos da COVID-19
Authors: Shocron Emilia
Published: September 2022

O interacionismo sócio-discursivo sustenta a ideia de que os enunciados não são responsabilidade exclusiva dos autores dos textos já que, através de diferentes mecanismos, eles transferem essa responsabilidade para outras instâncias enunciativas. No presente trabalho analisaremos fake news espalhadas por via de Whatsapp, Facebook e Twitter no marco da pandemia da COVID-19, visando identificar quais são os mecanismos que nos permitem reconhecer essa transferência e se, particularmente nesse contexto, se registra a transposição da responsabilidade enunciativa para vozes pertencentes à comunidade científica. Em consonância com esse objetivo, apresentaremos algumas das características principais do discurso científico segundo María Isabel Diéguez, para refletir sobre sua possível utilização por parte dos autores, na elaboração de fake news.

El estudio de la dinámica urbana, desde un enfoque temporal, se centra en determinar el avance de la superficie urbanizada y su incidencia en los cambios de usos del suelo. En primera instancia, es fundamental contar con un diagnóstico de la evolución espacial histórica, que nos permita realizar aportes orientados a la cuantificación y análisis del crecimiento urbano. En tal sentido, la Geografía, en su vertiente cuantitativa y racionalista, brinda los conceptos y metodologías de análisis espacial orientados a la generación de modelos cartográficos para el análisis de la distribución espacial. El presente trabajo tiene por objetivo realizar un análisis de la evolución espacial de áreas urbanas de la cuenca del río Luján, en un periodo temporal que abarca los años 1990 a 2010, a partir de cartografía temática e indicadores cuantitativos utilizando Sistemas de Información Geográfica. Los resultados alcanzados, indican un crecimiento urbano del 34% con respecto al periodo inicial, con una marcada diferenciación espacial según las categorías urbano compacto y disperso, siendo este último, el que mayor incremento ha presentado en el periodo bajo estudio.
Estrategias para la planificación de un territorio rururbano sustentable bajo el enfoque de inteligencia territorial caso vereda Bosatama Soacha Cundinamarca, Colombia
Authors: Bernal Sánchez Angela María , Hernández Peña Yolanda Teresa
Published: September 2022

La expansión urbana ha generado una transformación sin precedentes en el uso de los suelos, causando un impacto en la biosfera global con consecuencias ambientales, sociales y económicas, que es impulsado principalmente por un patrón de crecimiento físico tentacular expansivo poco regulado, asociado a procesos como la conurbación, la cual causa movimientos desconcentrados de personas y actividades económicas desde las grandes ciudades a las áreas rurales, generando procesos de rururbanización, que en el caso de la vereda Bosatama ha originado presiones y transformaciones en la ordenación del territorio como resultado de los cambio en el uso del suelo y el aumento de urbanización reflejado en el megaproyecto de vivienda Ciudad Verde. Conforme a lo expuesto, la investigación inicialmente estableció las tendencias mundiales de expansión urbana a partir de un sistema de búsqueda y análisis bibliográfico, con el propósito de definir los factores que influyen en la dinámica de conformación de la vereda, que junto con la aplicación del método Stlocus desde el enfoque de inteligencia territorial y la percepción de los actores claves permitió analizar las características y problemáticas de la vereda, que fueron evaluadas mediante una matriz Vester donde las problemáticas más críticas son el cambio del uso del suelo, la expansión urbana de la dimensión ambiental, el cambio de las actividades tradicionales y cotidianas de la dimensión social, debilitamiento de las actividades agropecuarias de la dimensión económica y falta de aprobación e implementación de un nuevo plan de ordenamiento territorial de la dimensión político institucional, las cuales fueron retomadas en el planteamiento de nueve estrategias para la planificación del territorio rururbano sustentable que articuladas desde un lineamiento de política de ruralidad, pueden contribuir en la resolución de las problemáticas presentes en la vereda.

Es importante destacar que el ordenamiento territorial es el conjunto de políticas que emanan desde el Estado, para planificar prospectivamente y gestionar el territorio a diferentes escalas; buscando un desarrollo sostenible que garantice equidad y calidad de vida para todos los ciudadanos. La geografía juega un rol fundamental en el ordenamiento territorial, por ejemplo, gracias a la geografía histórica, podemos conocer como las sociedades antiguas se organizaron formando comunidades para la protección mutua; las cuales fueron creciendo en tamaño y complejidad.
Género y comunicación: Narrativas de la organización popular
Authors:   , Martinuzzi María Emilia
Published: September 2022

Con el propósito de reconocer modos de organización y estrategias de lucha colectiva, en la presente tesis nos proponemos narrar y analizar de qué manera las experiencias de desigualdad de género y clase constituyen un emergente narrado por los grupos sociales que formaron parte del Programa Escuelas Populares de Género (EPG), que se llevaron a cabo desde 2013 al 2016 por la Facultad de Periodismo y Comunicación Social de la Universidad Nacional de La Plata (FPyCS-UNLP) en articulación con el Estado y las organizaciones sociales. Para cumplir con este propósito, nos interesa reflexionar a partir de zonas narrativas que organizan los interrogantes emergentes de la práctica. La primera de ellas se vincula con los modos en que la trayectoria del movimiento de mujeres en Argentina, en clave popular y latinoamericana, se han hecho presente en las escenas de interpelación y diálogo de las Escuelas Populares de Género, así como la articulación entre el rol de la universidad en su vínculo con las organizaciones y grupos sociales que desarrollan sus prácticas en territorios de la ciudad de La Plata y Ensenada han promovido procesos de participación y organización colectiva. En este sentido, y más cercano a los postulados del feminismo y a los aportes de los estudios culturales, el planteo teórico y el recorrido analítico-reflexivo que se encontrará a lo largo del trabajo integra experiencias de vida de mujeres populares, militantes y referentes de organizaciones sociales que nos permitirán reflexionar respecto de los proyectos políticos presentes y pasados, así como volver inteligibles las articulaciones ideológicas que hicieron posible la constitución de fuerzas sociales e históricas en Argentina reciente.

Published: September 2022

Despite the steady interest of biologists in the problem of invasions, the role of alien dominants in the formation of the vegetation cover of recipient regions has not yet been quantified. We compared the frequency and degree of dominance of alien and native plant species in nine sites of synanthropic vegetation in the vicinity of several settlements in the Republic of Adygea and the Krasnodar Territory (the Western Caucasus: the basins of the Belaya, Tuapse, and Agoy rivers; the Kuban-Azov Lowland). Within them, 1950 to 3683 (24847 in total) accounting plots of 1 m were established, on which the projective cover of the dominant species was estimated. The results showed that in the studied sites of synanthropic communities about 10% of the dominants identified were alien species. Compared to native dominants, they are characterized, on average (per species), by a slightly higher frequency of dominance and achievement of a coverage of more than 80% in most sites. At the same time, on average, for all sites, alien plant species dominate in 12% of the accounting plots (in different sites from 2 to 28%), and they reach coverages of more than 80% only on 2.9% of plots (0.04-7.7%). The species similarity between complexes of alien dominants in different sites is, on average, higher than the similarity of complexes of aboriginal dominants. This means that the strengthening of the positions of alien species leads to an increase in the homogeneity of synanthropic vegetation in southern Russia.

Communication Network Reliability under geographically correlated failures using Probabilistic Seismic Hazard Analysis
Authors: Barrera Javiera , Jiménez-Álvarez Dora , Cancela Héctor
Published: September 2022

The research community’s attention has been attracted to the reliability of networks exposed to large-scale disasters and this has become a critical concern in network studies during the last decade. Earthquakes are high on the list of those showing the most significant impacts on communication networks, and simultaneously, they are the least predictable events.  This study uses the Probabilistic Seismic Hazard Analysis method to estimate the network element state after an earthquake. The approach considers a seismic source model and ground prediction equations to assess the intensity measure for each element according to its location. In the simulation, nodes fail according to the building's fragility curves. Similarly, links fail according to a failure rate depending on the intensity measure and the cable's characteristics. We use the source-terminal, and the diameter constrained reliability metrics. The approach goes beyond the graph representation of the network and incorporates the terrain characteristics and the component's robustness into the network performance analysis at an affordable computational cost.  We study the method on a network in a seismic region with almost 9000 km of optical fiber. We observed that for source-terminal that are less than 500 km apart the improvements are marginals while for those that are more than 1000 km apart, reliability improves near a 30\% in the enhanced designs. We also showed that these results depend heavily on the robustness/fragility of the infrastructure, showing that performance measures based only the network topology are not enough to evaluate new designs.

RECENT DEVELOPMENT OF POLYSACCHARIDE BASED GEL: POROSITY BASED CLASSIFICATION AND A FUTURE PERSPECTIVE
Authors: Ishita Mukherjee
Published: September 2022

Polysaccharide is one of the most ancient and vast research field among natural sustainable biopolymers and they are readily available in nature as an essential component of our daily food. Hence, distribution of the entire field into some important factor-based classification like physical structure, stability, solubility become mandatory for clear understanding of whole polysaccharide chemistry. In some past decades, scientists mainly focused on general laboratory synthesis of this biopolymers with potential applications. Then, they broadened their vision to classify polysaccharide based composite materials and hydrogels based on majorly available polysaccharides in nature. Those gels are separated from entire polysaccharide based soluble biopolymers due to their three-dimensional physical or chemical crosslinked structure and hydrophilic, polymeric frameworks. But, a more compile classification was needed for better understanding of synthetic approach for those biodegradable hydrogels and their applications. Introducing gel porosity-based classification is a novel approach facilitating to understand the gel structure. The review mainly focused the recent advancement of polysaccharide-based gels with targeted porosity.

INTRODUCTION: IgG subclass deficiency was described by William Terry in a patient with recurrent infections. Selective IgG subclass is defined as a significant decrease in serum concentration of 1 or more IgG subclasses with normal total IgG, IgA and IgM levels. Persistent low serum levels of one or more immunoglobulin G (IgG) subclasses may be found in a high proportion of adult patients with increased susceptibility to infections (17). This deficiency has been described in association with other primary immunodeficiencies, including: selective IgA deficiency, selective IgM deficiency and Ataxia-Telangiectasia, growth hormone deficiency, Down syndrome, cystic fibrosis, among others (1).
CLINICAL CASE:We present the clinical case of a 28-year-old female patient with a history of selective immunodeficiency to IgG immunoglobulin, repeated urinary tract infections, repeated vaginal infections and herpes simplex II infection, all of which have been treated, She went to a hospital in Morona Santiago three days ago for presenting, as the apparent cause, administration of immunoglobulin for a basic illness, a mild holocranial headache that evolved into a severe headache, accompanied by nausea that led to vomiting on one occasion, for which she was admitted to the hospital for pain management. Complementary examinations showed that there was no metabolic alteration or neurological deterioration, which is why she was classified as an adverse effect of the administration of immunoglobulin 3 days earlier.
EVOLUTION:The patient was admitted for pain management due to severe headaches, multiple analgesics were administered without adequate response, so it was decided to start a tramadol infusion pump. During the following hours of hospitalization she remained with a feeling of nausea and weakness, however, the headache gradually subsided and it was decided to discontinue analgesic medication to assess the response of the clinical picture, and she was discharged 24 hours after admission with a favorable evolution.
CONCLUSIONS: IgG subclass deficiency is a pathology characterized by the fact that it occurs in women over 16 years of age, with a very low prevalence; the presence of respiratory pathologies gives rise to the suspicion of this disease. The treatment of this pathology is based solely on the intravenous or subcutaneous administration of Immunoglobulin G, together with the concomitant treatment of the infections that the patient presents. Adverse effects should always be taken into account, as they are temporary, but quite disabling.

COMMENT L’IA PEUT-ELLE JUSTIFIER LE BALLON D’OR ?
Authors: Rutambuka David
Published: September 2022

L’attribution du Ballon d’Or suscite beaucoup d’émotion et d’attention au sein de la communauté des amateurs de football. Malgré de nombreuses avancées dans le domaine des sciences des données et de l’intelligence artificielle, la désignation du meilleur joueur est toujours basée sur le vote de certaines personnes (exemple : journalistes), ce qui ne fait pas l’unanimité des amateurs de ce sport roi. Ainsi, la revue de la littérature existante en IA et sport ainsi que l’analyse des projets IA dans le sport nous permettent de proposer un modèle qui fait recours à l’intelligence artificielle pour tenter de mieux expliquer objectivement les critères d’attribution de cette récompense sur la base d’une note moyenne attribuée à chaque joueur.
$2\times n$ Grids have Unbounded Anagram-Free Chromatic Number
Authors: Bazarghani Saman , Carmi Paz , Dujmović Vida , Morin Pat
Published: September 2022

We show that anagram-free vertex colouring a $2\times n$ square grid requires a number of colours that increases with $n$. This answers an open question in Wilson's thesis and shows that there are even graphs of pathwidth $2$ that do not have anagram-free colourings with a bounded number of colours.
On Completing Partial Latin Squares with Prescribed Diagonals
Authors: Andersen Lars , Baumann Stacie , Hilton Anthony , Rodger Chris
Published: September 2022

Necessary and sufficient numerical conditions are known for the embedding of an incomplete latin square $L$ of order $n$ into a latin square $T$ of order $t \geq 2n+1$ in which each symbol is prescribed to occur in a given number of cells on the diagonal of $T$ outside of $L$. This includes the classic case where $T$ is required to be idempotent. If $t<2n$ then no such numerical sufficient conditions exist since it is known that the arrangement of symbols within the given incomplete latin square can determine the embeddibility. All examples where the arrangement is a factor share the common feature that one symbol is prescribed to appear exactly once in the diagonal of $T$ outside of $L$, resulting in a conjecture over 30 years ago stating that it is only this feature that prevents numerical conditions sufficing for all $t \geq n$.In this paper we prove this conjecture, providing necessary and sufficient numerical conditions for the embedding of an incomplete latin square $L$ of order $n$ into a latin square $T$ of order $t$ for all $t \geq n$ in which the diagonal of $T$ outside of $L$ is prescribed in the case where no symbol is required to appear exactly once in the diagonal of $T$ outside of $L$.
On the Turán Number of the Linear $3$-Graph $C_{13}$

Let the crown $C_{13}$ be the linear $3$-graph on $9$ vertices $\{a,b,c,d,e,f,g,h,i\}$ with edges $$E = \{\{a,b,c\}, \{a, d,e\}, \{b, f, g\}, \{c, h,i\}\}.$$ Proving a conjecture of Gyárfás et. al., we show that for any crown-free linear $3$-graph $G$ on $n$ vertices, its number of edges satisfy $$\lvert E(G) \rvert \leq \frac{3(n - s)}{2}$$ where $s$ is the number of vertices in $G$ with degree at least $6$. This result, combined with previous work, essentially completes the determination of linear Turán number for linear $3$-graphs with at most $4$ edges.
Density Maximizers of Layered Permutations

A permutation is layered if it contains neither $231$ nor $312$ as a pattern.It is known that, if $\sigma$ is a layered permutation, then the density of $\sigma$ in a permutation of order $n$ is maximized by a layered permutation. Albert, Atkinson, Handley, Holton and Stromquist [Electron. J. Combin. 9 (2002), #R5] claimed that the density of a layered permutation with layers of sizes $(a,1,b)$ where $a,b\geq2$ is asymptotically maximized by layered permutations with a bounded number of layers, and conjectured that the same holds if a layered permutation has no consecutive layers of size one and its first and last layers are of size at least two.

We show that, if $\sigma$ is a layered permutation whose first layer is sufficiently large and second layer is of size one, then the number of layers tends to infinity in every sequence of layered permutations asymptotically maximizing the density of $\sigma$. This disproves the conjecture and the claim of Albert et al. We complement this result by giving sufficient conditions on a layered permutation to have asymptotic or exact maximizers with a bounded number of layers.
Unknotted Cycles
Authors: Cornwell Christopher , McNew Nathan
Published: September 2022

Noting that cycle diagrams of permutations visually resemble grid diagrams used to depict knots and links in topology, we consider the knot (or link) obtained from the cycle diagram of a permutation. We show that the permutations which correspond in this way to an unknot are enumerated by the Schröder numbers, and also enumerate the permutations corresponding to an unlink. The proof uses Bennequin's inequality.
