La Antártica de la deriva : un retorno al habitar itinerante en el continente blanco
Authors:   ,   Pontificia Universidad Católica de Chile. Escuela de Arquitectura, Valenzuela Parra Sofía
Published: March 2023

La tierra se calienta, los efectos del cambio climático son cada vez mas notorios y se podría decir que la Antártica es el continente barómetro. Esto no sólo por su capacidad para demostrar las cantidades de dióxido de carbono con sus muestras, sino que también por su alta cantidad de agua dulce, importancia del mar congelado como superficie reflectora de luz solar que devuelve al espacio, etc. En consecuencia, la presencia humana permanente en el continente ha aumentado notoriamente en los últimos años, con científicos y turistas. Por otro lado, la Antártica se encuentra bajo un Tratado de Paz y colaboración científica (1959) que no ha dejado de lado el intenso proceso de reclamaciones territoriales durante los últimos años. A partir de esto, en el periodo post guerra, las naciones aumentan su presencia territorial, para lo cual construyen distintas bases en el continente blanco. La presente investigación considera los viajes heroicos como experiencias notables de colaboración científica y técnica que lograron habitar de forma itinerante en la Antártica, a través de distintos dispositivos de habitabilidad. La experiencia interdisciplinar del viaje promueve una lectura profunda e integral del territorio a través de sus diversas capas, una visión que se ve reflejada en viajes de Alexander Von Humboldt (1799-1804) y representada en diagramas: territorio + ciencia / notación científica y representación. A partir de lo anterior, se estudiarán estas distintas e itinerantes maneras de habitar el continente blanco, como auténticas formas de apropiarse de la Antártica. La primera aproximación al proyecto será a partir del levantamiento del comportamiento del mar y su congelamiento en la Antártica durante las distintas temporadas del año, llegando a duplicar su superficie en los periodos más fríos. El proyecto se sirve de la definición de Boris Ivelic (2005), sobre los objetos como dispositivos de habitabilidad arquitecturizada, para crear una estación flotante de colección, investigación, estudio marítimo y difusión científica, que se mueve con la formación de los hielos, desplazándose a la deriva, rodeando la península de oriente a poniente según las propias dinámicas del mar.
De campamento a poblado : plan de desarrollo urbano para asentamientos en el desierto : Estación Llanta - Región de Atacama
Authors:   ,   Pontificia Universidad Católica de Chile. Escuela de Arquitectura, Pucci Felipe
Published: March 2023

Existen tipologías urbanas en territorios desérticos que han permanecido activas por siglos, demostrando tener capacidades de adaptación al entorno y de permitir un desarrollo sostenible. La tesis propone rescatar principios de esta arquitectura vernácula y los presenta como soluciones a los desafíos propios de los modelos de ocupación actual en los desiertos. Esta arquitectura se basa en la generación de espacios habitables en distintas escalas urbanas, mediante filtros climáticos generados por la forma y la materialidad de su infraestructura. Se identifican ciertas estrategias de diseño que aportan a la protección frente a desastres naturales, al control climático del espacio público y a la organización colectiva entre los habitantes. Mediante una adaptación de estas tipologías vernáculas para su cooperación con las tecnologías contemporáneas de autosuficiencia energética, es posible el desarrollo de una nueva infraestructura urbana integral. La investigación estudia la formación y trayectoria de los poblados existentes en de la comuna de Diego de Almagro, en el desierto de Atacama, donde la precariedad de sus infraestructuras urbanas dificultan la posibilidad de un desarrollo sostenible y permanente. Se plantea intervenir el caso específico del poblado de Llanta, debido a su posición estratégica en el futuro escenario productivo de la comuna, como una oportunidad para la implementación de un nuevo modelo de ocupación urbana para el desierto.

Published: March 2023

Desde la ejecución de la remodelación San Borja a su estado actual hay discrepancias fundamentales por la instalación de rejas en toda su extensión. Esto repercute en una dimensión espacial, pero a la vez en lo social, creándose límites que dejan a grupos excluidos. A partir de esto, en la tesis se analizan desde distintos puntos de vista los procesos que dieron paso a esta situación, incluyendo una perspectiva social, política, normativa e histórica.
Identificación y caracterización de los mecanismos moleculares involucrados en el control de la distribución y almacenamiento de hierro durante el desarrollo de semillas de Chenopodium quinoa
Authors:   ,   Pontificia Universidad Católica de Chile. Facultad de Ciencias Biológicas, Ibeas Henríquez Miguel Ángel
Published: March 2023

El hierro es un micronutriente esencial para casi todos los organismos vivos. Los embriones acumulan hierro durante la etapa de maduración de la semilla de la embriogénesis. El déficit de hierro es un gran problema agronómico ya que afecta la rdesarrollo de las plantas y limita de fertilidad y rendimiento de los cultivos. Utilizando embriones de Arabidopsis thaliana ha sido posible determinar que el hierro se acumula específicamente en las vacuolas de las células de la endodermis. Utilizando la tinción Perls/DAB, fuimos capaces de identificar que este patrón de distribución es diferente en otros miembros de las Brassicales. Nosotros extendimos este estudio a embriones de especies pertenecientes a distintos órdenes de las Eudicotyledoneae. Nuestros resultados sugieren que el patrón de distribución de hierro observado en embriones de Arabidopsis no es conservado en otras Eudicotyledoneae. Notablemente, en embriones de Chenopodium quinoa el hierro se acumula en distintas capas celulares incluyendo las células del cortex y la endodermis. Interesantemente, identificados una gran cantidad de fitoferritinas en embriones de quinoa. Chenopodium quinoa es un pseudo-cereal de origen andino muy nutritivo que se caracteriza por crecer en diversos ecosistemas y ha alcanzado un alto nivel de atención debido a lo nutritivas de sus semillas. Por otro lado, nosotros observamos que durante el desarrollo de la semilla de Chenopodium quinoa el hierro se carga de una manera diferente a lo que observamos en el desarrollo de semillas de Brassica napus. Nuestros resultados abren nuevas preguntas respecto a cuáles son los mecanismos que controlan la carga, distribución y acumulación de hierro en semillas.

Published: March 2023

El hierro es un macronutriente esencial para todos los seres vivos. En humanos, la deficiencia de hierro en la dieta es la principal causa de anemia en el mundo. La Organización Mundial de la Salud a propuesto la biofortificación de cultivos como una alternativa para aumenta el contenido de hierro en los alimentos. Uno de los cultivos más consumidos en la dieta humana son las semillas. Sin embargo, poco se conoce sobre la acumulación del hierro en semillas. En Arabidopsis thaliana durante la maduración del embrión el hierro se acumula en las vacuolas de la capa celular que rodea la provasculatura. En A. thaliana y otras plantas modelo se han identificado tres factores de transcripción B3, FUS3 (FUSCA3), LEC2 (LEAFY COTYLEDON2) y ABI3 (ABSCISIC ACID INSENSITIVE 3), que cumplen una función crítica en la acumulación de compuestos de almacenaje como proteínas y lípidos en la semilla durante la maduración. La función de los factores de transcripción B3 en la maduración y la acumulación de compuestos de almacenaje ha sido bien estudiaba, sin embargo, la función de estos factores de transcripción B3 en la acumulación de micronutrientes como el hierro no ha sido estudiada. En este trabajo se estudió el rol de los factores de transcripción B3 en la homeostasis de hierro en semillas de A. thaliana, utilizando mutantes para los factores de transcripción B3 y técnicas histológicas y de biología molecular. En este trabajo se determinó que los factores de transcripción B3 participan en la regulación de la distribución de hierro en semillas de A. thaliana, pero no así el contenido total de hierro en semilla. Los resultados de este trabajo mostraron que los genes asociados a la homeostasis de hierro cambiaron su expresión en las semillas mutantes para los factores de transcripción B3. Este cambio en la expresión coincide con el fenotipo heterocrónico de las semillas mutantes en los genes de los factores de transcripción B3. Finalmente, a través de una Red de Regulación Génica se encontró un nuevo rol para la vía de respuesta a etileno asociado a la distribución de hierro en semillas. Estos resultados entregan algunas respuestas sobre la regulación de la homeostasis de hierro en semillas, a pesar de que aún quedan muchas preguntas sin respuesta, como, por ejemplo: ¿Cómo el etileno regularía la distribución de hierro en semillas? y ¿Qué factores de transcripción regulan directamente a los genes asociados a la homeostasis de hierro?
Análisis del rol de la cutícula en la defensa de la vid ante el hongo necrotrófico Botrytis cinerea
Authors:   ,   Pontificia Universidad Católica de Chile. Facultad de Ciencias Biológicas, Meyer Regueiro Carlos José
Published: March 2023

La cutícula es la estructura más externa de todos los tejidos aéreo de los organismos vegetales, por esta razón se encuentra en contacto inmediato con el medio circundante, interactuando con las distintas señales ambientales. Particularmente, es esta estructura la primera barrera que deben sobrepasar los patógenos fúngicos para colonizar el tejido aéreo vegetal. Por esta razón, su rol en la interacción planta-patógeno ha tomado relevancia en los últimos años. Se han propuesto tres mecanismos hipotéticos que podrían explicar las funciones de la cutícula en la interacción planta hongo: (1) Barrera física que impide la penetración del patógeno, (2) fuente de compuestos que afectan el desarrollo del hongo y (3) fuente de efectores percibidos tempranamente por la planta. Dentro del género Vitis, híbridos V. vinifera x V. labrusca presentan mayor grado de resistencia a este patógeno que su contraparte V. vinifera. Basados en la comparación de los componentes de la cutícula de ambas especies se determinó que en los cultivares derivados de V. labrusca existe una mayor acumulación de ácido ursólico, ácido olenólico y heintriacotano, moléculas que otorgan resistencia al hongo al ser asperjadas sobre bayas susceptibles. Este proyecto plantea estudiar la interacción entre B. cinerea y V. vinifera (híbridos V. vinifera x V. Labrusca) para contribuir a dilucidar cuál es el mecanismo de resistencia mediado por las ceras de la cutícula, a través de la caracterización de aspectos fisiológicos del ciclo infectivo del hongo en bayas de vid para dilucidar el componente principal de la resistencia a B. cinerea.
Impacto de las medidas sanitarias por el Covid-19 en los niveles de depresión y estrés materno, el desarrollo infantil y la calidad del vínculo en díadas madre-bebé prematuro hospitalizado al nacer
Authors:   ,   Pontificia Universidad Católica de Chile. Escuela de Psicología, Velozo Ramírez Francisca Belén
Published: March 2023

La prematurez y la hospitalización temprana constituyen un problema médico y psicosocial relevante. La vulnerabilidad dada por la inmadurez física del recién nacido y la separación abrupta de sus padres cuenta con evidencia científica suficiente para definir a este grupo como de alto riesgo. Es sabido que el desarrollo infantil temprano depende de la interacción del bebé con sus padres, por lo que en las unidades de cuidados intensivos neonatales se promueve su cercanía. Sin embargo, con la llegada del Covid-19 se tiende a limitar la presencia de las madres y los padres dentro de estas para proteger la salud de pacientes y funcionarios. En el presente estudio de seguimiento se analiza y compara la relación entre el nivel depresión y el estrés materno, el desarrollo infantil y la calidad del vínculo en díadas madre-bebé prematuro hospitalizado al nacer sin y con medidas sanitarias por el Covid-19. Participaron un total de 66 díadas atendidas en un recinto asistencial público de la Región Metropolitana entre octubre de 2019 y octubre de 2020. 36 de los recién nacidos pretérmino fueron ingresados antes de la pandemia y 30 con medidas por el Covid-19. Las díadas fueron evaluadas a través videollamadas y con cuestionarios de autorreporte. Los bebés presentan entre 15 y 28 meses de edad corregida al momento de su participación. Dentro de los resultados obtenidos, destaca una relación positiva y significativa entre el nivel de depresión y estrés materno y una negativa entre estos indicadores y el desarrollo del vínculo materno-infantil. No se aprecian diferencias entre los grupos estudiados al comparar las variables de salud mental materna y la calidad del vínculo, surgiendo una menor edad gestacional del bebé al nacer y la lactancia materna como factores protectores de la relación. Los bebés ingresados durante la pandemia presentan mayores dificultades en el área de la comunicación que los hospitalizados sin medidas sanitarias, diferencia que se hipotetiza tendría relación con la separación temprana madre-bebé, agudizada por la pandemia, ya que en la relación de apego se daría inicio a la capacidad de simbolización y de mentalización del niño/a. Se concluye que la intervención psicosocial sería una herramienta eficaz para prevenir dificultades de salud mental en las madres durante el período perinatal, en contextos de prematurez y sanitarios complejos. Sin embargo, resulta necesario incluir de manera más activa las necesidades socioafectivas de los bebés prematuros dentro de las intervenciones, para así poder atender a los requerimientos de ambos miembros de la díada, los que pueden diferir.
¿Qué sucede con los movimientos? Reacciones ante éxitos parciales : movimiento feminista frente al aborto en tres causales
Authors:   ,   Pontificia Universidad Católica de Chile. Instituto de Sociología, Marín Álvarez José
Published: March 2023

Durante los últimos años se ha desarrollado en Chile y el mundo un incremento en la acción colectiva de movimientos feministas, con demandas que apelan hacia una mayor equidad de derechos para las mujeres. Una de las peticiones históricas del movimiento feminista en Chile ha sido la despenalización del aborto, demanda que en 2017 fue incorporada como ley a través de la aprobación de la “ley de interrupción voluntaria del embarazo en tres causales” (IVE). Este proyecto generó diversas reacciones internas en movimiento heterogéneo como el feminista, tanto en términos ideológicos, tácticos, políticos y de repertorios de acción colectiva. Esas reacciones van desde la colaboración, satisfacción con la ley, apoyo crítico y rechazo absoluto. De esta manera, este proyecto de tesis busca investigar qué elementos inciden en las diferentes reacciones que tiene el movimiento feminista frente a la ley de aborto en tres causales. A través del método process tracing con entrada inductiva, se demostrará que las variadas reacciones del movimiento ante un proyecto de ley gradual varían a lo largo del tiempo. En una primera instancia, que contempla el contexto previo de la aprobación de la ley, la presencia de un contra-movimiento conservador tanto a nivel político, social e institucional generan un reordenamiento discursivo, especialmente frente a la oposición política mostrando una posición de colaboración hacia el proyecto. Además, la inexistencia de una política nacional de aborto abría un abanico de posibilidades ante un eventual proyecto que avanzara hacia la despenalización, lo que generó una colaboración técnica y política de muchas organizaciones feministas. Durante la discusión de la ley, existe una unificación y colaboración de las organizaciones por lograr el objetivo, en términos de colaboración, satisfacción y apoyo crítico. Posterior a la implementación de la ley, con el cambio de gobierno y un contexto político de movilización social internacional, el discurso y las tácticas se han radicalizado, volviendo a las demandas de aborto libre y seguro con mayor presencia del movimiento en la opinión pública, desplegando estrategias de apoyo crítico y colaboración. Sin embargo, se observa la aparición de un fuerte activismo profesional para que se cumpla la ley, a pesar de ser considerada como “ley de mínimos”.
ECOLOGICAL AND ECONOMICAL BENEFITS FROM SEWAGE SLUDGE HYGIENISATION WITH THE USE OF LIME IN A MEDIUM-SIZE TREATMENT PLANT
Authors: STACHOWICZ Feliks , WÓJCIK Marta
Published: March 2023

Sewage sludge classified as hazardous waste requires searching for advanced and more effective methods of utilization. Waste produced in treatment plants, should be subject to proper reprocessing on the grounds of health, economic and legal reasons. In treatment plants, hygienisation with the use of lime (CaO) is commonly applied. The main advantage of the aforementioned method is the growth of pH value of sewage sludge and the reduction of pathogens. Apart from this, sewage sludge hygienisation with the application of lime is characterized by the high costs associated with the acquisition of lime. Assuming the price of highly reactive lime ranging from EUR 67-82 per one tone, additional cost of approximately EUR 8600 is generated for a medium treatment plants per year. Additionally, the liming of sewage sludge requires the modernization of treatment plants and the acquisition of new equipment. But due to the fertilizing properties of aforementioned waste, the agricultural utilisation of sewage sludge is the best method for small and medium treatment plants. The financial feasibility analysis showed that the whole undertaking will pay off within 7 years. This paper presents the cost-effective analysis of sewage sludge hygienisation in medium municipal treatment plant. In this article, the main mechanism of process and the influence of liming on sewage sludge characteristics are also showed.

Em tempos de coronavírus e de distanciamento social, ressignificações passaram a ser fundamentais em diversos setores da sociedade brasileira, inclusive no jornalismo. Em relação ao jornalismo televisivo, as práticas cotidianas precisaram ser transformadas, visando a preservação tanto dos membros das equipes de reportagem, como das fontes. Desta forma, atividades comuns na rotina telejornalística, como a captação de imagens, a realização de entrevistas e o contato com as fontes, precisaram tomar novos contornos e os telejornais de referência passaram a assumir novas práticas, como uso de máscara por parte dos repórteres e realização de entrevistas pela internet. Desta forma, este trabalho é focado na observação das transformações nas rotinas do Jornal Nacional em virtude do coronavírus. Vamos observar três edições, que foram ao ar nos dias 23 de março, 23 de abril e 23 de maio de 2020.
AFINAL, COMO ESCREVER UM ARTIGO CIENTÍFICO?
Authors: Silva Junior Lenilton Damião da , Borges Luiza Alexandre
Published: March 2023

Objetivamos investigar estratégias inovadoras de abordagem e produção do gênero acadêmico artigo científico (AC) no contexto do curso de Letras da XXXXX. De modo mais específico, objetivamos construir um panorama da produção de textos no Ensino Superior, conhecer os aspectos discursivos e notacionais do AC, e refletir sobre a importância das Sequências Didáticas (SD) no contexto da mediação e produção dele. A pesquisa surgiu a partir da identificação de que os referidos alunos têm dificuldade para escrever AC por nunca terem tido contato com o gênero e/ou por não haver a mediação adequada dele. Baseamo-nos em Costa e Salces (2013), Araújo e Bezerra (2013) e Motta-Roth e Hendges (2010), que discorrem sobre a escrita acadêmica, bem como as contribuições de Dolz, Noverraz e Schneuwly (2004) sobre sequências didáticas. Trata-se de uma pesquisa de abordagem qualitativa e natureza exploratória, que tem como corpus dois AC escritos por alunos da UPE. Com base na técnica de análise de conteúdo (Bardin, 2016), elencamos três categorias: tema e título, o plano global do texto e questões de estilo. Os resultados reiteram a necessidade da abordagem do AC por meio de SD, pois são verificadas fragilidades tanto na produção do texto ofertado pelos estudantes do 3º período, quanto na produção dos estudantes do 5º período. Fica evidente que não foi apresentado o gênero; não foram analisados modelos desse texto, tampouco houve quanto ao contexto de produção do texto, o que sinaliza outros problemas que perpassam a produção textual: ortográficos, gramaticais; de seleção lexical e estilo.
RECORTE AUTOBORIGRÁFICO DE UM CORPO NEGRO BAILARINO, PESQUISADOR E PROFESSOR
Authors: Cruz Jessé Da , Cunha Claudia Madruga
Published: March 2023

Laroyê Exú abre caminhos neste artigo para tratar de um processo de “percepção”, “afectos” e “criação”, ligados à construção de um estilo “borigráfico” na dança que expressa um corpo negro. Apoiados nos pensadores da diferença Deleuze; Guattari (2012) e nas perspectivas pós-coloniais vindas de Fanon (2008); Mbembe (2018); outros, ousamos a criação de uma autoBORIgrafia, processo metodológico que se envolve com as macumbarias exusíacas, próximas de Rufino (2019) e com a cartografia deleuziana-guattriana; ou seja, provoca alianças entre o rizoma e a encruzilhada, associa a cartografia ao cruzo quando propõe a sobreposição de três momentos e planos concomitantes para dizer das potencias de um corpo negro bailarino e professor. Sendo o 1º, a afeção, algo que acontece ou perpassa; o 2º, O que se desdobra dessa atenção demarca e pede enfrentamento; e o 3º, demanda criar uma nova ação ou ponto de vista ainda não proposto. Esses três elementos dizem de uma metamorfose do pensar (CUNHA, 2011), que movimenta um corpo negro como expressão de um pensamento outro, singular, produtor de resistências e experimentações.
AFROFUTURISMO NO BRASIL: UMA LEITURA DO ROMANCE O CAÇADOR CIBERNÉTICO DA RUA 13 E SUA RELAÇÃO COM A CONSTRUÇÃO DE UMA IDENTIDADE AFRO-BRASILEIRA NA FICÇÃO CIENTÍFICA
Authors: Silva Rhuan Felipe Scomação Da
Published: March 2023

Este trabalho analisa o romance O caçador cibernético da rua 13, de Fabio Kabral, a partir dos conceitos do afrofuturismo, como herança e identidade, procurando demonstrar como a ficção científica se mostra importante na construção de um novo imaginário acerca da literatura afro-brasileira. A partir dos conceitos de Mark Dery (1994) e Laura Burocco (2019) acerca do afrofuturismo, e das contribuições de Conceição Evaristo (2009) e Eduardo Duarte (2008) acerca da construção de uma identidade e de um conceito de literatura afro-brasileira, este trabalho procura entender a maneira como o escritor emprega a herança (cultural) africana e constrói uma narrativa que dialoga com um público nacional, evidenciando a importância cada vez mais eminente da literatura e das mídias em geral para o rompimento de espaços hegemônicos da cultura ocidentalizada.

Published: March 2023

Essa pesquisa apresentará uma reflexão sobre as resistências técnicas e cognitivas dos artistas periféricos de Blumenau, a partir do conceito de Corpo sem Órgãos de Deleuze e Guattari (2011). Elas foram percebidas durante a execução do Projeto “SUPRIMIDO PARA AVALIAÇÃO AS CEGAS”, em 2022. Os participantes entrevistados foram moradores de regiões periféricas de Blumenau, artistas, artesãos e performers cujas identidades faziam parte de suas produções visuais. Como local periférico, considerou-se o local de pertença cultural em relação ao contexto de Blumenau, que mantém a colonialidade de poder (SUPRIMIDO, 2021). O Projeto levou etnofotografia de moda para artistas e produtores visuais periféricos, no intuito de divulgar o conhecimento, reconhecer as identidades periféricas e mapear as criações e produções artísticas e visuais de Blumenau em locais invisibilizados. Para descrever a relação da periferia com o contexto foi efetuada a cartografia e uma análise das fotografias efetuadas durante o Projeto. O conceito de Corpo sem Órgãos fundamentará as discussões em três categorias: a eminência do Corpo sem Órgãos cheio; do Corpo sem Órgãos vazio e/ou do Corpo sem Órgãos canceroso nas produções visuais periféricas. As resistências apresentadas e discutidas a partir desse conceito, , relacionaram-se com a cor da pele, gênero, transgeneridade, analfabetismo virtual e moradia em locais distantes da região central, e estão diretamente conectadas às escolhas culturais do rap e hip hop, performance vogue, arte de rua e tradições manuais que, desprendidas do ideal germânico institucionalizado, encontraram local de pertença periférico, e marginalizado, e ali discorrem suas revoluções estéticas nas artes visuais.

Published: March 2023

An experiment was conducted to identify the appropriate time of planting for red ant management and increase the tuber yield of potato at Agriculture Research Station (ARS), Jaubari, Ilam, Nepal (2900 masl) during 2020 and 2021 planting season. Seed potatoes were planted in 9 different plant dates that were December 1, December 15, January 1, January 15, February 1, February 15, March 1, March 15 and April 1. The experiment was laid out in Completely Randomized Block Design (RCBD) with three replications. The variety used for experiment was Janakdev. The plot size for the experiment for each treatment was 4.5m2 with spacing of 75 cm x 25 cm. Data were collected on vegetative characteristics, tuber yield parameters, red ant damage scoring (1-5 scale), red ant incidence (%) in tuber and red ant infested yield (t/ha). Potatoes planted at first January produced highest tuber yield and minimum red ants infestation. Early planting delayed emergence but had maximum ground coverage. In both the years tuber was highest (19.86 t/ha and 25.48 t/ha respectively in 2020 and 2021) with seed tuber planted on January 1. Tuber yield was less both in early and late planted potatoes. Along with higher tuber yield potatoes planted on January 1 had the lowest red ant damaged score, red ant incidence (%) and less red ant infested potato tuber yield (t/ha) in both the years. It is recommended that for maximum tuber yield and minimum red ants infestation seed potatoes should be planted during first week of January in Jaubari area and similar conditions in the hills of Nepal.

Authors: Swathi Naraparaju , Jabeen Asra , Devi Barla Karuna , Kumar Anumolu Durga Pani
Published: March 2023

Background: Ganciclovir is a synthetic analogue of 2′-deoxy- guanosine, used in the treatment of cytomegalovirus infection. The aim of the present investigation was to develop and validate a simple, rapid and sensitive redox-based spectrophotometric method for the quantification of Ganciclovir in pure and in pharmaceutical dosage form.

Methods: It was developed by using 0.1 M HCl as solvent and mixture of ferric chloride and 1,10-phenanthroline as chromogenic reagent. The developed method was optimized for various method conditions and then statistically validated.

Results: The mixture containing 0.3% w/v of ferric chloride and 0.5% w/v of 1,10-phenanthroline and drug to reagent mole ratio of 0.5:0.5, were identified as optimum for the method, based on the optimization studies. Linearity of the method was found to be 5.0-30.0 μg/mL for Ganciclovir, when the measurement was done at 510.0 nm. The method was proved to be sensitive by its low limit of detection and quantification values i.e., 0.30 and 0.90 μg/mL, respectively. The results of the validation parameters comply with the ICH guidelines. The %assay value 99.2 indicated the successful adaptation of the contemplated method for the pharmaceutical formulation.

Conclusion: The developed method was simple and could be applied in the quality control testing of Ganciclovir in formulation.
Models for Predicting Strength Reduction Factors for Concrete that Utilizes Palm Kernel Shells and Waste Automobile Tires as Aggregates
Authors: Boateng Eric , Kankam Charles K. , Danso Anthony K.
Published: March 2023

Palm kernel shells (PKS) and waste automobile tires do not only enhance the properties of concrete (e.g. damping ratio, ductility, impact resistance etc.), but also their rational utilization can significantly reduce carbon footprints and environmental pollution globally. In this study, a multivariate regression analysis was carried out to develop models for predicting the reduction factors and thereafter the strengths (compressive strength, flexural tensile strength, split tensile strength and bond strength) of concrete that utilizes PKS and waste automobile tire chips as partial to full replacement of the conventional crushed granite stones as coarse aggregates.  The strength reduction factors, , were modelled as a function of the total aggregate replacement level (TAR), and the volume of PKS (P)  and tire (T) particles in a given concrete mix whilst the performance of the models was assessed using the Mean Squared Error (MSE) and the Coefficient of Determination () techniques. After studying several mathematical functions, it was found that a single linear regression model can be used to predict the strength reduction factors for all the mechanical properties of the concrete tested but with different function parameters. The values of the  ranged from 0 to 1 depending on the aforementioned factors. However, a   of 0.53 (53%) can be achieved at the 50% optimum replacement where P50T50 for any of the mechanical properties. Furthermore, for each of the concrete properties, the  was positively correlated with the volume of PKS but negatively correlated with the TAR level and volume of tire particles in the concrete matrix. Thus, an increase in the TAR level or tire content decreases the and vice versa. In conclusion, the proposed models can be used to establish the target strengths of PKS.
The deserted settlement at Lix, West Perthshire
Authors: Fairhurst Horace
Published: March 2023

[NN 5629]. Lix is typical of the late 18th and early 19th century settlement pattern in the SE Highlands, consisting of scattered clusters, or clachans, of up to eight rectangular buildings. Using documentary evidence, field survey and excavation, the morphological arrangement of the settlement was established in some detail, showing that two successive transformations had taken place. Three group-tenancy farms evolved from the old clachans soon after 1780; at Middle and West Lix, further amalgamation and depopulation took place in the mid-19th century, but at East Lix the joint-tenancy farm was replaced by small-holdings before the process of consolidation began about 1830. Excavation of a typical byre-dwelling provided detailed information about interiors in the early 19th century. A R

Midden 1, 14C-dated in 13th century bc, yielded seeds of wild plants, and analysis of the shellfish and animal bones in both middens suggests that occupation of the site was temporary and based on domesticated animals, with some consumption of shellfish. Midden 1 contained local Flat-Rimmed ware, noticeably different from the Covesea variety, and reinforcing the impression that this class of pottery cannot be used for dating since it spans the 3rd to the 1st millennia BC.

NR 644873. A seasonal camping site was represented by a layer of occupation material on a terrace above Lussa River; excavation yielded insects, seeds, charcoal, red ochre, pumice, a human hair and 1500 flint and quartz artefacts. Chisels and microliths predominate amongst a tool assemblage which is seen as the last of three microlithic phases in N Jura; radiocarbon dates fall in third millennium bc. The relationship between sites on Jura and Oronsay is discussed and doubt is thrown on the cultural status of the "Obanian".

Painted pebbles in early Scotland
Authors: Ritchie Anna
Published: March 2023

Pebbles with simple but carefully-painted designs are unique to Caithness and the Northern Isles between 3rd and 8th centuries AD. Their apparent connection with Pictish culture is supported by some sharing of motifs with the repertoire of the Pictish symbol stones. They may be charm stones like those known from medieval sources and folklore; the Life of St Columba also contains a reference to a healing stone.

The church of St Nicolas, Aberdeen
Authors: Hunter John
Published: March 2023

Excavation in the transept of St Nicholas' Church suggests that the original building dates from 1153-57 and not, as previously claimed, to 11th century. Evidence for medieval modifications is described, and there is an architectural and an archaeological account of the pre- and post-Reformation features of the building. The archaeology of the church is shown to have a bearing on the history and growth of the medieval city. R K M

A Bronze Age cemetery at Ferniegair, Lanarkshire
Authors: Welfare Humphrey G
Published: March 2023

NS 739540/740538. Exiguous field notes, contemporary newspaper articles and a confused published report were used to reconstruct the excavation of a small cemetery in 1936 and 1939. The burials comprised four inhumation cists, four urned cremations and a simple inhumation. Artefacts included a Beaker decorated with fingernail impressions, at least three Food Vessels, an Enlarged Food Vessel, an 'Encrusted' Urn, a Cordoned Urn containing an archer's bracer, some fabric woven from vegetable fibre, and a cist-slab decorated in 'passage-grave' style.

A multi-disciplinary chronology for Alt Clut, Castle Roack, Dumbarton
Authors: Alcock Leslie
Published: March 2023

Small scale excavations at this early British stronghold were performed as part of a long term research programme on early historic fortifications in Scotland (here listed). Historical, archaeological and 14C evidence are combined to produce a historical account, identify the fortification implied by Bede in 731, and attribute its destruction to the Vikings Olafr and Ivarr the Boneless in 870. The 14C dates are best read as implying construction after 600, possibly after 650. Au(adp)
Excavation at Iona Abbey, 1976
Authors: Redknap Mark , Sheldon J M , Wells Calvin , Saunders Amanda
Published: March 2023

NM 287245. Traces of pre-Benedictine activity, including post-holes, demonstrated that 'St Columba's Shrine' preceded the 15th century tower abutting its E end. The 'Shrine' is likely to have been a free-standing chapel, which was later incorporated into the Benedictine plan. Six graves were associated with its use, two containing the remains of wooden coffins. The finds include Iron Age and medieval pottery, a fragment of an inscribed 8th or 9th century grave-slab, and part of a cross-base. Report on skeletal material. A R

Leather guns and other light artillery in mid-17th century Scotland
Authors: Stevenson David , Caldwell David H
Published: March 2023

Leather guns were a 17th century experiment in gun manufacture that began in Switzerland and was adopted in Scotland. Their advantage was lightness: a relatively thin metal barrel was tightly wound with rope, wire or cord and encased in leather. Twenty-three such guns exist in Scotland, representing six types, and as a whole are distinguished from other European examples by several special features. James Wemyss in Fife was the principal Scottish maker, and a full discussion of the historical background is provided. A R
A corbelled Bronze Age burial chamber and Beaker evidence from the Rosinish machair, Benbecula
Authors: Crawford Iain A , Denston C B
Published: March 2023

NF 872537. An oval corbelled cist was built in a pit cut into earlier Beaker midden deposits and covered by a low mound of sand. The crest of the mound was defined by a circle of stones laid flat to form a kerb. The cist contained one male and two female inhumations, a decorated biconical urn and a possible pendant of limestone. Beyond the kerb were two small cists, one containing a plain pot. AR.

Excavations at the Catstane, Midlothian 1977
Authors: Cowie Trevor G , Lunt D A , Young A
Published: March 2023

NT 148743. Excavation around the Catstane confirmed disturbance at its foot and revealed long cist burials arranged to respect a space 7-8m diameter round the stone. Results of excavating 52 graves to E and SE of the stone failed to correlate with the 19th century excavation report, and bone preservation was poor. A 5th century start for the cemetery is suggested. A R

NS 843798. The N and W ramparts of the fort and part of the praetentura were examined. The 'additional margins' of the W rampart were shown to be an ascensus on the inside, and interleaved road surfaces and rampart tumble on the outside. The earliest structures in the praetentura appeared to be temporary and were followed by two timber buildings, presumably barrack-blocks. All evidence for putative Antonine II buildings had been removed in 1903 but there were traces of ?lean-to buildings against the inside races of the W and N ramparts. Occupation continued into the early 160s. Au(abr)
