Published: May 2024

Experiments on the electrochemical oxidation of ethylene glycol (EG) have been carried out in laboratory conditions using lead dioxide titanium anode (LDOTA) in electrochemical cell. It has been found that the chemical oxygen consumption in the solution on LDOTA at a current density of 5.5 A/dm2 and processing time of 120 min is reduced to the values that allow its further bio-purification. It has been concluded that the efficiency of the electrochemical oxidation process, leading to further destruction of the EG molecule, is explained by both direct oxidation, in which the hydroxyl radicals arise that oxidize EG on the anode surface, and indirect oxidation, accompanied by the formation of strong oxidizing agents, for example, peroxodisulfuric acid anions capable of oxidizing the organic matter in the solution volume.

Published: May 2024

Nowadays, there has been an urgency in the search for sustainable energy sources, such as those derived from biomass. This search is not only limited to minimizing greenhouse gas emissions but is also related to the increasing scarcity of fossil fuels. This work aims to investigate and analyze the production of bio-hydrocarbons from fatty acids through the simulation of the deoxygenation reaction by the DWSim software. In this simulation, a continuous catalytic deoxygenation reactor of the stirred tank with fluidized bed type was selected, aiming to understand the influence of operating parameters on this reaction. The parameters evaluated were temperature, pressure, hydrogen feed, and catalyst mass. For this simulation, hydrogen and stearic acid were chosen as feedstocks, focusing on the heptadecane and octadecane production. The rate law was chosen based on an extensive literature review, as well as reaction conditions. The kinetic model used as a reference was based on reactions of stearic acid and hydrogen in the presence of NiMo/Al2O3 as a catalyst. A stearic acid feed of 2.4 x 104 m3 year-1 was used as a base, representing the average feed of fatty raw material practiced in biodiesel plants located in the state of Minas Gerais, Brazil. From the variation of these parameters for a sensitivity analysis, with conversion as the key response, the following optimal operating conditions were defined: temperature of 650 K, pressure of 50 bar, molecular hydrogen feed of 4.1 x 10-3 m³ s-1, and catalyst mass of 8 kg. Under these new circumstances, the conversion of stearic acid reached a value of 99.23 %. The simulation of this reaction allowed us to understand the effect of the main reaction parameters on the reaction products, proved to be an important and robust tool to be used in projects and feasibility analyses of plants and biorefineries.
Profanar a natureza, instituir o comum: fundamentos filosófico-políticos para a educação ambiental
Authors: Petry Cleriston , Amorim Filipi Vieira
Published: May 2024

O artigo parte do pressuposto de que é necessária uma reaproximação entre os conceitos e as palavras que designam as percepções e entendimentos acerca da ideia de natureza, quando se trata dos estudos no campo da educação ambiental. Assim, o objetivo do texto foi o de revisitar os aspectos teórico-conceituais que auxiliam na compreensão da natureza, aproximando-a da fundamentação histórica, política e filosófica. Trata-se de um ensaio teórico que tanto se aproxima quanto se afasta, propositalmente, do campo da educação ambiental, justificando-se pela tentativa de alargamento do horizonte compreensivo de seus fundamentos. O estudo propõe a profanação da natureza e a instituição do comum como possibilidades ao campo em tese.
Lupus in fabula. Owidiańska metamorfoza w średniowieczu na przykładzie pseudoowidianum De lupo
Authors: Jegorow Adam
Published: May 2024

This paper examines the role of Ovidian backdrop in the textual transmission of a medieval pseudo- Ovidian poem De lupo. The aim of the analysis is to explain in the light of medieval poetics some dynamics concerning the false authorial attribution, by showing a common understanding of thematic and functional affinities between Metamorphoses and the animal literature in the educational processes. The subsequent textual transformations are demonstrated by the manuscript evidence of three Polish 15th-century codices (Kraków, BJ 2141, 2233; Wrocław, Biblioteka Uniwersytecka, IV Q. 126), which transmit a latter alternative version of the poem.
Fauna w Tygodniu stworzenia świata Wacława Potockiego
Authors: Głuszak Patrycja Katarzyna
Published: May 2024

The article is a study of the historical and literary background, as well as the encyclopedism of an early poem by Wacław Potocki, Tydzień stworzenia świata (The Creation Week). The author of the article discusses the classification of various animal species found in the poem and, basing on examples from the poem, shows the zoological prowess of the baroque poet, who ascribes various traits and properties to the creatures. The essay concludes with a proposal that curiositas (Latin for curiosities) present in the poem serve as an expression of Hexameron’s central truth — “God made the wild animals according to their kinds, the livestock according to their kinds, and all the creatures that move along the ground according to their kinds. And God saw that it was good” (Genesis 1:24– 25).
Kanibalistyczna uczta. O wszechcierpieniu fauny i flory w Niedokonanym Tadeusza Micińskiego
Authors: Borek Bartłomiej
Published: May 2024

Since antiquity the depiction of nature has been involving subjective observation of the space surrounding, and often has been overwhelming, its observers. Beginning with the motif of locus amoenus and concluding with locus horridus, literary representations of fauna and flora have become more and more intriguing. The portrayal of nature in Tadeusz Miciński’s poem Niedokonany seems to be an adequate example of such a riveting depiction. This peculiar sea of darkness, much like an enclave without an exit, is a trap for anyone who dives into it.
In the article the author presents significant findings about the gnostic view of nature. Special attention is paid to the motifs of cricket, phoenix, lotus in Egyptian culture, and to the motif of predatory wasp, analysed in the context of the Bergsonian interpretation of the insect’s maternity phenomenon.

Authors: Szymczak-Maciejczyk Barbara
Published: May 2024

The charpenter delivers an analysis of a human condition in the collection of stories entitled Two moons. The author considers the issue of the relationship between man and nature. The writer made the division of society into red moon’s people and white moon’s people. The first group is composed of craftsmen, merchants, farmers and beggars. The second group includes the artists and their muses and patrons.
Nature is different for each of these communities — the former respects mainly useful plants: fruits, cereals, trees; the second appreciates the fragrant flowers or shrubs. The author presented the above-mentioned division of flora, showed what it depends from and what was the purpose of using this type of perception of the world.
Czesława Miłosza zmagania z naturą
Authors: Głuszak Michał
Published: May 2024

The aim of the article is to present Miłosz’s reflections on nature. It was the issue that the poet found particularly engaging. Starting from his childhood, which he spent in a manor house in the village of Szetejnie, Lithuanian nature and nature related rituals became the object of childhood’s fascination for the author of Rescue. The picturesque valley, avenue of lime trees, oak grove, hunting, picking mushrooms, celebration of Pentecost. That was what shaped the future poet and affected his sensitivity. With time, Milosz saw the darker side of nature. The inevitability of death, the unrelenting passing, brutality, tough law governing the whole of creation, according to which the stronger beats the weaker. This discovery forged a fascinating adventure in intellectual as well as literary sense. The text shows the evolution of the relationship between Miłosz and the world of nature. The relationships that is thought to be quite complex and full of ambiguity. I dedicate my consideration mainly to Miłosz’s most important novel The Issa Valley and selected works of his lyric poetry.

Hidrógeno verde: abriendo las puertas a un futuro energético sostenible en el Perú
Authors: Aranibar Ramos Edgar Romario , Olarten Pacco Miguel Angel Demetrio
Published: May 2024

La preocupación por el cambio climático ha impulsado la búsqueda de soluciones energéticas sostenibles. En este contexto, el hidrógeno verde se destaca como una opción emergente y prometedora, dada su producción libre de emisiones de carbono y extensa aplicabilidad. No obstante, su abordaje académico a nivel peruano es aún escueto. A partir de ello, se tiene como objetivo analizar el potencial del hidrógeno verde en el Perú, considerando aspectos técnicos, económicos, ambientales y regulatorios. El estudio se basa en una revisión de la matriz energética actual peruana, identificando sus retos y limitaciones, y explora las oportunidades y ventajas que este podría ofrecer en el contexto nacional, examinando también experiencias internacionales. Se observa que el Perú posee una matriz energética diversa, pero enfrenta retos en términos de infraestructura, dependencia de combustibles fósiles y vulnerabilidad a fluctuaciones de precios internacionales. El hidrógeno verde tiene el potencial de aprovechar los recursos naturales renovables y ofrece beneficios económicos, ambientales y sociales, así como una mayor diversificación y seguridad energética. Se concluye que la implementación exitosa del hidrógeno verde en el Perú requerirá abordar obstáculos técnicos, establecer un marco regulatorio sólido y garantizar el acceso a financiamiento asequible. Las experiencias internacionales resaltan la colaboración entre el gobierno, industria e instituciones académicas para acelerar el desarrollo de estas tecnologías. Asimismo, el establecimiento de un marco regulatorio y político que proporcione seguridad y fomente la colaboración es menester. Una limitación del trabajo es que aborda sucintamente el ámbito de costo de las plantas de producción, punto posible de futuras investigaciones.

Authors:   Korean Home Economics Education Association, Shim Jaeyoung , Choi Saeeun
Published: May 2024

The purpose of this study is to explore the direction of home economics education and provide specific implications to help adolescents develop relationship competency. For this purpose, the contents of Korea's character education and UK's relationships education curriculum were analyzed, and the results are as follows. Character education in Korea focused on character education values such as responsibility, respect, consideration, and communication throughout the public education system. These contents were largely consistent with the learning content elements for cultivating relationship-competency in home economics education. UK's relationships education at the primary and secondary levels were similar to that of home economics education in middle school in Korea in its goals and learning contents for understanding and maintaining healthy relationships. However, differences existed in areas of safe relationships, setting boundaries with others, comprehensiveness of sex education content, rights to refuse sex education, and education content based on equal rights. Based on these results, this study concludes that the concept of education on relationships needs to be defined, the composition of educational content should be systematically developed, and further research on the development of teaching and learning methods and learning programs that can elicit and internalize students' attitudes and changes is needed. In addition, insights were gained regarding additional educational contents and considerations to take into account.

Published: May 2024

The purposes of this study are to obtain an in-depth understanding of the experiences of novice Home Economics teachers during their first year and to extract meaning from the experiences. The Photovoice was used as a research methodology. Participants in the study included three novice Home Economics teachers who passed the 2022 secondary school teacher recruitment examination and began working at middle schools in the Seoul metropolitan area from March 2022. Data were collected from February 2022 to January 2023, involving one written interview, nine monthly Photovoice projects, and two Focus Group Interviews. Thematic analysis was utilized for data analysis. The narratives of novice Home Economics teachers were divided into the narratives as ‘Home Economics teacher’ and as ‘Novice teacher’. As being Home Economics teachers, participants constructed their narratives around three themes: ‘Home Economics is a practical discipline’, ‘Home economics teachers are agents of change’, and ‘Home Economics is undervalued in the school.’ Furthermore, the sub themes of the ‘novice teachers’ narrative included ‘Now it's the real beginning’, ‘Teaching is a wonderful profession’, and ‘I will become a good teacher.’ The significance of this study lies in the in-depth exploration of the lived experiences of novice Home Economics teachers during their first year and broadening the use of Photovoice as a research and teaching strategy.

Through a review of aquaponic techniques, the present work highlights the interest aroused by this practice in the world as well as different modes of exploitation. Aquaponics is defined as a coupling between a recirculated aquaculture compartment and an aboveground crop compartment. Since two decades, it has been the subject of a significant economic activity in Canada, the USA, Australia and induces numerous research activities. This system is subdivided into three (3) major techniques which are the culture techniques on bed of inert substrates, on nutritive film and that of rafts. Aquaponics is the subject of profitable industrial economic activity on both large and small scale in the USA and Canada. Given the benefits of low water consumption, then on-use of fertilizers and pesticides, aquaponics is unquestionably according to researchers and users, the system capable of revolutionizing livestock farming and agriculture around the world. Côte d'Ivoire is suffering not only from the consequences of climate change but also from rapid urbanization, with the consequent change in water resources. Aquaponics deserves to be mastered then popularized in this country, to help produce fish and plants of better quality while avoiding the waste of water caused by traditional livestock systems.

Published: May 2024

Soft magnetic materials are important components of electronic devices. Knowledge of the exact magnetic properties of these materials is essential for the design of devices that utilize them. We tested the possibility of measuring the inductance factor (Al), static effective permeability (μeff) and static initial permeability (μi), complex permeability (μ’ and μ”) of a ferrite core using electrical impedance spectroscopy (EIS). B(H) hysteresis curves were also recorded using the same setup. This allowed the estimation of the values for the coercive field (HC) and for the saturation magnetic polarization (Bi). The material selected for the test is 3F3 and the type of the core used is P26/16. The results obtained from our measurements are of the same order of magnitude as the magnetic properties specified by the manufacturer.

The growth of micro, small, and medium-sized enterprises (MSMEs) is critical to Indonesia's present economic development. This study has the purpose of examining how financial literacy, financial inclusion, and access to capital affect the performance of MSMEs in the Banyumas area. The performance of MSMEs is the dependent variable in this study, and the independent factors are financial literacy, financial inclusion, and access to finance. This study used partial Least Squares (PLS) to handle data in this work. Purposive sampling procedures were employed to select 127 MSMEs from a total of 8,559 MSMEs in the Banyumas Regency as research participants. The study's main findings of the relationship between the three variables of financial literacy, financial inclusion, and access to capital on MSME performance show that these three variables significantly influence MSME performance, both partially and simultaneously. As a result, MSMEs with a high degree of financial competence, simple access to finance, and suitable access to capital would improve MSMEs' performance in an area, resulting in the growth of the enterprises they manage. This research found that the financial literacy level of Banyumas MSMEs is quite high, available financial inclusion is easily accessible and sufficient access to capital can help MSMEs to improve their performance so that they can increase the development of the businesses they run.

The findings of this research provide important implications for the JABODETABEK region in developing strategies to increase sharia financial inclusion. Apart from that, this research can also be a reference for further research in the same field and contribute to a deeper understanding of related theories.
Review of salivary antioxidants and their barriers
Authors: Nelson Ashlianne , Santosh Arvind Babu Rajendra , Jones Thaon
Published: May 2024

Background: Oxidative stress results from the imbalance between reactive oxygen species (ROS) and cellular antioxidant defenses. Oxidative stress can cause damage to cellular structures such as cell membranes, lipids, proteins, lipoproteins, and deoxyribonucleic acids when free radicals are present in excess. Antioxidant mechanisms protect tissues against oxidative stress by decreasing free radical levels in cells through the inhibition of activities or expression of free radical-generating enzymes. Purpose: The purpose of this paper is to discuss the role of antioxidants in protecting cells from the harmful effects of ROS, particularly in the context of oral mucosa, and to clarify which molecules disrupt the pathway of these antioxidants. Review: Salivary peroxidase, catalase, superoxide dismutase, and glutathione reductase are enzymatic salivary antioxidants, and uric acid, reduced glutathione, albumin, and lactoferrin are non-enzymatic antioxidants. Both types of antioxidants regularly donate an electron to free radicals to reduce their levels in cells. Conclusion: Antioxidant activities may be disrupted by signaling mechanisms resulting from barrier regulations observed in tissue. The increased expression of malondialdehyde is an indicator of disrupted antioxidant barriers.

ЦИФРОВА ТРАНСФОРМАЦІЯ ПРОМИСЛОВИХ ПІДПРИЄМСТВ ЯК ЗМІНА БІЗНЕС-МОДЕЛІ ТА КОРПОРАТИВНОГО МИСЛЕННЯ
Authors: Дергачова В. В. , Колешня Я. О.
Published: May 2024

У статті розглядається сутність цифрової трансформації як процесу, що за своєю сутністю є більш складним та комплексним, ніж цифровізація. На основі дослідження зарубіжних публікацій виявлено, що цифрова трансформація передбачає вплив на бізнес-модель підприємства, який проявляється у зміні кількох елементів бізнес-моделі, у тому числі таких ключових як продукт, цінність, основні види діяльності. Розглянуто процеси цифрової трансформації компаній GE, John Deere виявлено, що вони мають досить схожі етапи, такі як цифровізація з метою підвищення ефективності використання власних активів; формування цифрової платформи для підвищення власної ефективності та надання цінності власним клієнтам; відкриття платформи для використання іншими підприємства. За результатами розгляду трансформаційних проектів GE, John Deere доведено, що цифрова трансформація передбачає використання діджитал технологій, що призводить до переосмислення бізнесу, переосмислення продукції та послуг, надання їм додаткової цінності, заснованої на інформації та технологіях, до зміни ключових елементів бізнес-моделі або її повної трансформації з формуванням цифрової компанії. Розглянуто приклади українських компаній, що відповідають ознакам цифрової трансформації та відображають схожий досвід, зокрема, ДТЕК, МХП, Kernel. Проаналізовано статистичні дані щодо використання деяких цифрових технологій українськими підприємствами, зокрема 3D-друк та аналітика Великих даних, які свідчать про те, що цифрова трансформація не є масовим явищем для українського бізнесу, проте тенденції на ринку свідчать про інтенсифікацію процесів цифровізації. На основі проведеного дослідження можна зробити висновок, що незважаючи на складні умови господарювання, українські підприємства мають потенціал до цифрової трансформації, однак це потребує не лише ресурсів (які доступніші великим підприємствам), а й наявності трансформаційного мислення у керівництва, усвідомлення необхідності цифрової трансформації, формування з цією метою відповідної корпоративної культури.
ПРИНЦИПИ ГЕНДЕРНОЇ РІВНОСТІ ТА СОЦІАЛЬНОЇ ІНТЕГРАЦІЇ У КОНТЕКСТІ ПРОЦЕСУ ЗАЛУЧЕННЯ ГРАНТОВИХ РЕСУРСІВ
Authors: Кобеля-Звір М. Я.
Published: May 2024

Стаття демонструє аналіз принципу гендерної рівності та соціальної інтеграції (ГРСІ). Така рівність та інтеграція сприяють розвитку інклюзивної політики та акцентують увагу на зміцненні впливу соціально виключених, жінок та осіб із низьким рівнем доходу. Принцип гендерної рівності та соціальної інтеграції, врахований у контексті залучення грантових ресурсів, підтверджує, що це дві взаємопов’язані концепції, спрямовані на покращення можливостей доступу різних соціальних груп до заходів проекту, його продуктів та результатів. Гендерна рівність та соціальна інтеграція є актуальними під час реалізації соціальних, екологічних та бізнес-проектів, зокрема тих, що фінансуються за рахунок грантових коштів. У дослідженні продемонстровано, як принцип ГРСІ проявляється в пріоритетах національних, міжнародних та європейських програм. У статті відображено, як принцип ГРСІ проявляється в конкурсній документації Українського культурного фонду, Програми USAID з аграрного і сільського розвитку (AГРО) та Програми Horizon Europe. Зроблено акцент на тому, що в процесі залучення грантових ресурсів принцип гендерної рівності та соціальної інтеграції є наскрізним. Тому розробникам грантових проектів необхідно бути відповідальними щодо ГРСІ та враховувати його під час розробки всіх розділів грантової заявки, щоб претендувати на високі бали від експертів фондів. На основі проведеного дослідження напрацьовано ряд рекомендацій для розробників проектних пропозицій щодо формування ключових розділів проектної заявки, в яких необхідно відображати принцип, а саме: «Аргументація проблематики проекту», «Стратегічна ціль проекту», «Мета та завдання проекту», «Методологія проекту», «Цільова аудиторія», «Команда проекту» та «Залучені особи», «Продукти та результати проекту», «Моніторинг та оцінка проекту», «Комунікація проекту», «Сталість та масштабування проекту». Підсумовано: в процесі залучення грантових ресурсів організаціям-заявникам важливо проаналізувати вимоги грантодавців та врахувати критерії оцінювання по обраному конкурсу, аби забезпечити дотримання принципу ГРСІ.

З швидким розвитком цифрових технологій та збільшенні потоків медичної інформації існує потреба в поліпшенні ефективності опрацювання даних та пришвидшенні прийняття рішень. Можливість інтеграції штучного інтелекту (ШІ) в сферу охорони здоров’я є можливим шляхом вирішення цих проблем. Метою даної роботи є аналіз впливу штучного інтелекту на галузь медицини та його потенційні переваги та виклики. ШІ виявляє значний потенціал для автоматизації процесів діагностики, лікування та управління медичною інформацією, забезпечуючи прискорення та покращення якості медичних послуг. Однак існують ризики та виклики, такі як недостатня прозорість алгоритмів, етичні питання та обмежені можливості розуміння контексту. Існують серйозні проблеми щодо конфіденційності особистих даних, етичності вирішень та відповідальності за прийняття рішень, які виникають з використанням ШІ в медицині. Несприятливі впливи на автономію, невідповідність та конфіденційність особистих даних розглядаються як серйозні етичні виклики, які потребують уважного вирішення. Попри потенційні обмеження, ШІ може стати значущим інструментом для вдосконалення медичної практики, але досягнення повного потенціалу вимагає подальших зусиль у вирішенні етичних та безпекових питань.

El aprendizaje bajo enseñanza STEM y el trabajo por proyectos se ha extendido ampliamente, pero aún quedan preguntas acerca de su reproducibilidad y eficacia en diferentes contextos académicos latinoamericanos. El objetivo de este trabajo es describir el desempeño de estudiantes de ingeniería de una zona rural y de una urbana de San Luis Potosí, México, en la fabricación de un deshidratador con fines de preservación de alimentos, evitando el uso de la refrigeración y para alargar el tiempo de vida. Se hizo un estudio cualitativo, descriptivo y observacional, con un análisis del proceso de aprendizaje y de los secadores obtenidos. Se encontraron diferencias en la elección de la fuente de energía, el producto a secar, y los materiales utilizados. Los grupos participantes evidenciaron tener empatía, actitudes positivas al trabajo colaborativo y resiliencia, mejoraron sus habilidades de comunicación oral y escrita. Hubo diferencias sobre las concepciones hacia las energías renovables. Los estudiantes refirieron haber cambiado su creencia hacia la complejidad de la fabricación de prototipos y su relación con los modelos matemáticos. Este trabajo puede ser una guía para que profesores menos experimentados puedan desarrollar un proyecto STEM.
Análisis del artículo 666 del nuevo Código de Procedimientos Civiles y Familiares mexicano en relación con los procesos de carácter internacional sobre niñas, niños y adolescentes
Authors: Virginia Aguilar María
Published: May 2024

En este artículo se examina la importancia de la defensa especializada en el ámbito del derecho familiar e internacional en México, con un enfoque particular en la protección de los derechos de niñas, niños y adolescentes, tal y como se establece en el artículo 666 del Código Nacional de Procedimientos Civiles y Familiares. Ante el crecimiento de los casos de sustracción internacional y las complejidades inherentes a los procedimientos de restitución y adopción que involucran a extranjeros o mexicanos residentes en el extranjero, en este estudio se destaca la necesidad crítica de una especialización legal obligatoria que se alinee con tratados internacionales y la legislación nacional. Utilizando un enfoque cualitativo, la investigación se basa en el análisis normativo y doctrinario, revisión de tratados internacionales y consulta de fuentes doctrinarias y jurisprudenciales, para abordar las lagunas legales y los desafíos interpretativos presentes en la legislación actual. Los hallazgos revelan una falta de especificidad en el Código sobre los tratados aplicables y los procedimientos a seguir, subrayando la urgencia de formar profesionales del derecho altamente especializados en estas materias.

As homelessness remains an urgent public health crisis in the United States, specific programs in the US Department of Veterans Affairs (VA) system may serve as a roadmap for addressing it.

We examine lessons learned from the first decade (2012–2022) of the Supportive Services for Veteran Families (SSVF) program, a cornerstone in the VA continuum of homeless services aimed at both preventing homelessness among those at risk and providing rapid rehousing for veterans and their families who are currently experiencing homelessness. Drawing on information from annual reports and other relevant literature, we have identified 3 themes of SSVF that emerged as features to comprehensively deliver support for homeless veterans and their families: (1) responsiveness and flexibility, (2) coordination and integration, and (3) social resource engagement.

Using these strategies, SSVF reached nearly three quarters of a million veterans and their families in its first decade, thereby becoming one of the VA’s most substantial programmatic efforts designed to address homelessness. We discuss how each feature might apply to addressing homelessness in the general population as well as future research directions.

Management strategy for overwintering cyanobacteria in sediments contributing to harmful algal blooms (HABs)
Authors: McQueen Andrew , Calomeni-Eck Alyssa , Kinley-Baird Ciera , Smith Elizabeth , Clyde Gerard , Boyer Marvin
Published: May 2024

Cyanobacteria that cause harmful algal blooms (HABs) can overwinter in sediments as resting cells (akinetes or vegetative colonies) and contribute to seasonal bloom resurgences. However, to date there has been limited focus on management tactics specifically targeting the control of cyanobacterial sources from sediments. Targeting resting cells in sediments for preventative management may provide a viable approach to delay onset and mitigate blooms (Calomeni et al. 2022). However, there are limited resources for this novel strategy. Given the growing global impact of HABs, there is a need to develop management strategies focused on sediments as a potential source and contributor to HABs. Therefore, the objective of this report is to provide a management strategy in terms of approaches, information, and case study examples for managing overwintering cyanobacteria in sediments with the goal of mitigating seasonal HAB occurrences.

High dose dietary vitamin D allocates surplus calories to muscle and growth instead of fat via modulation of myostatin and leptin signaling.

Obesity occurs because the body stores surplus calories as fat rather than as muscle. Fat secretes a hormone, leptin, that modulates energy balance at the brain. Changes in fat mass are mirrored by changes in serum leptin. Elevated leptin prompts the brain to decrease appetite and increase energy expenditure. In obesity, however, impaired leptin sensitivity mutes these leptin-mediated changes. We have limited understanding of what controls leptin production by fat or leptin sensitivity in the brain. Muscle produces a hormone, myostatin, that plays a role in muscle analogous to the one that leptin plays in fat. Absent myostatin leads to increased muscle mass and strength. As with leptin, we also do not know what controls myostatin production or sensitivity. Although fat mass and muscle mass are closely linked, the interplay between leptin and myostatin remains obscure. Here we describe an interplay linked thru vitamin D. Conventionally, it is thought that vitamin D improves strength via trophic effects at the muscle. However, we find here that high dose dietary vitamin D allocates excess calories to muscle and linear growth instead of storage as fat. Vitamin D mediates this allocation by decreasing myostatin production and increasing leptin production and sensitivity. That is, high dose vitamin D improves integration of organismal energy balance. Obesity, aging and other chronic inflammatory diseases are associated with increased fat mass and decreased muscle mass and function (e.g. sarcopenia). Our work provides a physiologic framework for how high-dose vitamin D would increase allocation of calories to muscle instead of fat in these pathologies. Additionally, our work reveals a novel link between the myostatin and leptin signaling whereby myostatin conveys energy needs to modulate leptin effects on calorie allocation. This result provides evidence to update the conventional model of energy stores sensing to a new model of energy balance sensing. In our proposed model, integration of leptin and myostatin signaling allows control of body composition independent of weight. Furthermore, our work reveals how physiologic seasonal variation in vitamin D may be important in controlling season-specific metabolism and calorie allocation to fat in winter and muscle and growth in summer.

The possibility of inducing new polar and/or magnetic transient states through the pumping of optical phonons towards the non-linear regime has renewed the scientific interest in orthoferrites. Nonetheless, to perform these studies it is fundamental to have a deep knowledge of the lattice excitations at equilibrium conditions. In this work, we present a complete characterization of the optically-active zone-center phonons in NdFeO3 single crystals at room temperature and at 4 K, by means of polarized Raman and infrared spectroscopies. All the predicted optical phonons were successfully observed together with some of the crystal-field excitations. First-principles simulations further allow the eigenmode and symmetry assignments of the optical phonons. The calculated atomic motions of each mode are of significant interest, as they are common for all orthoferrites and to most of the large family of orthorhombic Pbnm perovskites.
