Nonwoven fabric sheet with back air space serving as Helmholtz resonator
Authors: Sakamoto Shuichi , Nozawa Takumi , Sato Kodai
Published: March 2024

The sound absorption effect of a Helmholtz resonator was induced by creating an aperture in a nonwoven fabric sheet with a back air space, thus obtaining a sufficient sound absorption effect in a broad frequency range. In this study, transfer matrices were used to obtain the sound absorption
coefficient. Transfer matrices were used to represent the following mathematically: a nonwoven fabric model based on the simplified limp-frame model, an acoustic element that considers the vibration of the nonwoven fabric sheet, the air space behind the nonwoven fabric sheet, and the aperture
of the nonwoven fabric sheet. Equivalent circuits combining these transfer matrices were used to obtain sound absorption coefficient. The Helmholtz resonator sound absorption effect was more pronounced for the nonwoven fabric sheets with greater ventilation resistance. The results showed consistency
between the experimental and theoretical trends. As for the sound absorption coefficient derived using the theoretical models for nonwoven fabric sheets, the results of the simplified limp-frame model were the closest to the experimental values. As the length of the back air space increased,
the peak sound absorption value shifted toward low frequencies due to the sound absorption principles of both the nonwoven fabric sheet with a back air space and the Helmholtz resonator.

Background

First contact physiotherapy practitioners (FCPPs) are embedded within general practice, providing expert assessment, diagnosis, and management plans for patients with musculoskeletal disorders (MSKDs), without the prior need for GP consultation.

Aim

To determine the clinical effectiveness and costs of FCPP models compared with GP-led models of care.

Design and setting

Multiple site case-study design of general practices in the UK.

Method

General practice sites were recruited representing the following three models: 1) GP-led care; 2) FCPPs who could not prescribe or inject (FCPPs-standard [St]); and 3) FCPPs who could prescribe and/or inject (FCPPs-additional qualifications [AQ]). Patient participants from each site completed outcome data at baseline, 3 months, and 6 months. The primary outcome was the SF-36 Physical Component Summary (PCS) score. Healthcare usage was collected for 6 months.

Results

In total, 426 adults were recruited from 46 practices across the UK. Non-inferiority analysis showed no significant difference in physical function (SF-36 PCS) across all three arms at 6 months (P= 0.667). At 3 months, a significant difference in numbers improving was seen between arms: 54.7% (n= 47) GP consultees, 72.4% (n= 71) FCPP-St, and 66.4% (n= 101) FCPP-AQ (P= 0.037). No safety issues were identified. Following initial consultation, a greater proportion of patients received medication (including opioids) in the GP-led arm (44.7%,n= 42), compared with FCPP-St (18.4%,n= 21) and FCPP-AQ (24.7%,n= 40) (P<0.001). NHS costs (initial consultation and over 6-month follow-up) were significantly higher in the GP-led model (median £105.5 per patient) versus FCPP-St (£41.0 per patient) and FCPP-AQ (£44.0 per patient) (P<0.001).

Conclusion

FCPP-led models of care provide safe, clinically effective patient management, with cost-benefits and reduced opioid use in this cohort.

Authors: Kurian Thomas , Kozhikodanparambil Abhitha , Jabbar Shincy Alamparambil
Published: March 2024

Dipiperazine thiuramdisulphide (DPTD) prepared in the laboratory using piperazine, triethyl amine and carbon disulphide as reactants acts as an accelerator for the vulcanization of natural rubber.  The DPTD synthesised in our laboratory was characterized   by FTIR, CHNS and the estimation of amine value. Results of the MTT assay   test shows that the    DPTD is a safe (non-carcinogenic) chemical. For comparable dosages of the accelerator, the DPTD based latex   and dry natural rubber (NR) vulcanisates show improved mechanical properties   as compared to tetramethylthiuram disulphide (TMTD) based vulcanisates. DPTD may be considered as a safe replacement for the nitrosamine generating TMTD in natural rubber based formulations.

Published: March 2024

Salinization is a threat to global agricultural and soil resource allocation. Current investigations of global soil salinity are limited to coarse spatial resolution of the available datasets (>250 m) and semiqualitative classification rules (five ranks). Based on these two limitations, we proposed a framework to quantitatively estimate global soil salt content in five climate regions at 10 m by integrating Sentinel-1/2 remotely sensed images, climate, parent material, terrain data, and machine learning. In hyper-arid and arid region, models established using Sentinel-2 and other geospatial data showed the highest accuracy with
R
2
of 0.85 and 0.62, respectively. In semi-arid, dry sub-humid, and humid regions, models performed best using Sentinel-1, Sentinel-2, and other geospatial data with
R
2
of 0.87, 0.80, and 0.87, respectively. The accuracy of the global models is considerable with field validation in Iran and Xinjiang, and compared with digitized salinity maps in California, Brazil, Turkey, South Africa, and Shandong. The proportion of extremely saline soils in Europe is 10.21%, followed by South America (5.91%), Oceania (5.80%), North America (4.05%), Asia (1.19%), and Africa (1.11%). Climatic conditions, groundwater, and salinity index are key covariates in global soil salinity estimation. Use of radar data improves estimation accuracy in wet regions. The map of global soil salinity at 10 m provides a detailed, high-precision basis for soil property investigation and resource management.

Materialidad, procesos de producción y espacios de circulación de la cerámica de Casira, pueblo alfarero argentino
Authors:   , Paltrinieri Agustina
Published: March 2024

Casira es un pequeño pueblo de Jujuy declarado “capital alfarera”. Se encuentra al pie de la frontera internacional entre Argentina y Bolivia y está habitado por una comunidad indígena que sostiene y actualiza experiencias tradicionales de producción cerámica prehispánica. Estas tradiciones tecnológicas se encuentran asociadas arqueológicamente a la comunidad étnica Chicha y al estilo alfarero Yavi que, según los restos cerámicos estudiados, habitan el territorio andino desde hace al menos mil años. Más cerca del presente, en los últimos años algunos maestros alfareros de Casira han comenzado a participar en determinados espacios de circulación del arte cerámico argentino, inscribiendo sus prácticas en nuevas tramas de sentido. La presente tesis aborda las prácticas cerámicas casireñas atendiendo a los espacios de circulación, los procesos productivos y la materialidad cerámica casireña. Para ello, proponemos un diálogo interdisciplinario con trabajos arqueológicos, etnográficos y procedimientos de las ciencias de los materiales. Presentamos un recorrido posible que toma la teoría del arte como punto de partida para estos diálogos y ensayamos algunas respuestas visuales a partir de la fotografía como un lenguaje artístico que nos permite aproximarnos a lo que proponemos como experiencia cerámica. Este concepto nos permite articular la historia de la cerámica con las expresiones concretas que desarrolla en cada territorio, atendiendo también a las relaciones que despliega entre culturas, tiempos, personas y otras existencias no-humanas como la materialidad cerámica y las lógicas minerales.

Published: March 2024

The aim of the study was to investigate the current surgical approaches and complications of delayed reconstruction of pharyngeal and pharyngoesophageal defects in patients with malignant neoplasms of the larynx and pharyngeopharynx after laryngectomy using different reconstructive materials. There are various classifications of pharyngoesophageal defects in the current literature, in which one should pay attention to the shape, size, and structure of the pharyngeal defect. The Blackwell and Urken classification is the most widely used in the choice of plastic material. The Blackwell and Urken classification distinguishes the following types of pharyngoesophageal defects: Type 0 - small defects that close mostly without tissue introduction; Type 1 - noncircular defects that retain a viable band of mucosa from the laryngeopharynx to the cervical esophagus; 2 type - circular defects that extend from the valleculae, that is, the depression between the root of the tongue and the lingual surface of the epiglottis, and down to the thoracic entrance; 3 type - circular defects that extend from the level of the valleculae and cranially to the oropharynx; 4 type - extensive defects that extend below the clavicles to the thoracic esophagus. The types of defects and types of plasty with the use of different plastic material depending on the type of defect are considered.
In the delayed reconstruction of pharyngeal and pharygoesophageal defects in cancer patients various plastic materials are used: from the covering tissues, the material on the axial blood supply (deltopectoral, pectoral, thoracodorsal), free flaps (radial forearm flap, anterolateral thigh flap) and visceral flaps from fragments of the gastrointestinal tract, allowing to restore the integrity and lumen of the throat. At all types of plasty complications can develop in the postoperative period.

This research aims to analyze the effect size of using the Project-Based Learning (PjBL) model on problem-solving abilities in mathematics learning and investigate the effect size based on educational levels. The research method employed is quantitative with meta-analysis, aiming to summarize, evaluate, and integrate the results of several published studies. Data collection techniques involve documentary studies by searching national and international journals published between 2015 and 2023. A total of 24 studies met the predetermined inclusion and exclusion criteria, and the effect sizes of each study were calculated. Subsequently, the overall average effect size and effect sizes based on educational levels were calculated. Data analysis was conducted using JASP software version 0.18.1.0. The results of this research indicate that the effect size of the Project-Based Learning model on problem-solving abilities in mathematics learning is significantly large, with an effect size of 0.973. Furthermore, statistically significant differences were reported in the effect sizes of the PjBL model on problem-solving abilities in mathematics learning across educational levels. The implementation of the PjBL model has a very large effect size on problem-solving abilities in mathematics learning for elementary, and college-level students. Meanwhile, at junior high school  and the senior high school level, the PjBL model on problem-solving abilities in mathematics learning has a large and amoderate effect size.
El "Otro" en la ética de E. Levinas. Implicaciones para la educación
Authors: Ortega Ruiz Pedro
Published: March 2024

El autor aborda en este artículo la necesidad de promover e impulsar otra manera de “estar en el mundo” y de relacionarse con los demás desde la ética de la compasión. Nada se puede cambiar sin analizar las causas que provocan la situación actual de individualismo que lleva a construir sociedades de individuos aislados, atomizados sin vínculos que les unan a proyectos compartidos en su propia comunidad. El autor describe los efectos del idealismo en la configuración de nuestra sociedad y aboga por la ética de la compasión como “herramienta” que puede favorecer la construcción de una sociedad justa, equitativa y solidaria, es decir, una sociedad con rostro humano. El autor expone en este trabajo los rasgos fundamentales de la ética levinasiana, subrayando la incondicionalidad de la respuesta ética y la asimetría de la misma. La condición de sujeto depende del otro que nos interpela desde la autoridad que le confiere su situación de vulnerabilidad. Nadie es humano por sí mismo, es el otro quien nos hace humanos. El autor aboga por asumir el reto de una ética de la compasión que fija su respuesta en el otro concreto vulnerable, en “el extranjero, el huérfano y la viuda”, en expresión feliz de Levinas. Así mismo, propone como estrategia para una educación en la responsabilidad acudir a la experiencia del alumno como contenido de toda educación y la creación de un clima ético en el aula. Finalmente, señala la exigencia de ir a las raíces del “mal”, de una sociedad que ha hecho de la indiferencia y la frialdad su característica principal. Propone volver a las raíces de nuestra cultura. Ello conlleva un trabajo constante de denuncia y resistencia, a la vez que la memoria de los que nos han precedido.

El reconocimiento de la identidad cultural es fundamental dentro del proceso de enseñanzaaprendizaje por su influencia formativa en los estudiantes del nivel superior; sin embargo, algunos de los profesionales en formación inicial de la carrera Educación Artística presentan insuficiencias en el conocimiento de los elementos que representan los valores identitarios de la nación cubana, por lo que se propone un conjunto de actividades docentes y extensionistas para solucionar las insuficiencias referidas. Las actividades poseen una estructura didácticometodológica que permite aplicarlas en el contexto escolar y comunitario, tomando en cuenta los niveles de desempeño de los estudiantes y la influencia socioeducativa de los agentes y agencias del entorno. En el artículo se exponen los resultados de la aplicación de la propuesta, con lo que se evidencia su utilidad práctica desde la apreciación, comprensión y disfrute de los elementos que representan las expresiones artísticas y valores identitarios de la nación.

Ataques e censuras a docentes que discutem gênero na educação básica no interior do Estado de Santa Catarina
Authors: Menin Assis Felipe
Published: March 2024

O presente trabalho pretende demonstrar como a ascensão e a influência de uma direita radicalizada, com características neoliberais e neoconservadoras, a nível global, impactou as discussões de gênero e diferença sexual nas escolas do interior de Santa Catarina a partir da emergência de uma ideologia antigênero. Este trabalho apresenta ainda como ocorre esse ataque local, quais são as suas estratégias (dispositivos) e qual o impacto dessas ações na comunidade e indivíduos pertencentes a ela. Utilizando do enfoque da História Oral e adotando uma metodologia da pesquisa multissituada, entrevistamos docentes, das 6 regiões do estado catarinense. Esses ataques ocorreram (e ocorrem) de forma organizada através de censuras e perseguições nas redes sociotécnicas, de políticos, religiosos, imprensa e da própria comunidade escolar ao abordar a temática em questão. Apontamos ainda que a intensão do neoconservadorismo é o silenciamento dessas temáticas em sala de aula. No entanto, essa tentativa de censurar e proibir, tem tido efeito contrário e positivo na vontade de saber mais, por parte dos(as) estudantes e na própria resistência dos(as) docentes a esses ataques.

Published: March 2024

Gênero e território se entrelaçam no debate sobre relações sociais de poder, sendo con- ceitos fundamentais para a compreensão da realidade do campesinato brasileiro. O artigo reflete sobre os processos de territorialização das organizações das mulheres quebradeiras de coco a partir de suas práticas e acordos para acesso, uso e gestão do babaçu, no território do Médio Mearim, Maranhão. Evidencia a conexão entre estudos de gênero e campesinato a partir da realidade do trabalho das quebradeiras de coco babaçu, assim como discute desdobramentos na aplicação da Lei do Babaçu Livre na territorialidade da mulher quebradeira de coco e sua luta pela valorização da coleta e quebra do babaçu. O estudo concluiu que as práticas e acordos de acesso e uso no contexto relacionado ao manejo do babaçu resultam na construção do território em que a territorialidade é marcada pelas relações de poder. Além disso, o estudo concluiu que a trajetória das quebradeiras de coco babaçu indica que reterritorializar campos desiguais a partir da perspectiva de gênero é o passo mais importante para construir políticas públicas mais efetivas, pois a desigualdade social no campo somente será superada se houver também combate à desigualdade de gênero.

Published: March 2024

O presente artigo visa problematizar o papel dos processos comunicacionais na gestão da educação como estratégias de motivação da comunidade escolar e de deliberação acerca de ações e comportamentos que alcancem melhores resultados. Nas próximas linhas, aportamos um arsenal teórico que compreende a comunicação como estratégia motivacional relevante para a gestão de organizações, em especial de unidades de educação. Para tal, se utilizou os aportes de vários teóricos notadamente os de Edgar Morin, Jürgen Habermas, Maslow, McClelland, Deci e Ryan, Luke; Calegari e Pereira e Mintzberg. A discussão possibilitou compreender que em organizações educacionais existe um nível de complexidade de funcionamento e de relações que requer estratégias que motivem os estudantes a se engajarem no processo de ensino aprendizagem, tendo como resultado o sucesso demonstrado em indicadores de desempenho.
