A Theoretical Study to Incorporate Capillary Tubes Action and Evaporation Process as Green Energy Techniques for Water Lifting
Authors: Mohammed Tawfeeq W. , Mohammed Marwah N. , Eleiwi Muhammad A. , Ibrahim Thamir K.
Published: January 2024

Abstract: The idea proposed in this study can be used in remote areas to lift the water spontaneously instead of using electrical pumps. This research aims to lift the underground water to a high altitude by designing a passive system that simulates the rising water in tall plants due to capillary action and evaporation. The study assumed a set of micro-tubes to lift the underground water to a tank. The flow rate due to capillary rise and evaporation were analytically determined by mathematical models based on energy equations in fluid mechanics calculated using MATLAB software. The study results have shown that a ‎system consisting of 2-10 billion micro-tubes can supply between 16-65 kg of water daily to a tank, depending on the ‎environmental conditions‎. It was found that a set of tubes with a 20 μm diameter was a suitable choice to raise the water to 7.5 m, where 0.8 m rising was due to the capillary action, whereas the rest was due to the evaporation process suction head.
Pseudogout mimicking cervical spine osteomyelitis and ventral epidural abscess: A case report and literature review
Authors: Wilkinson Brandon Michael , Draytsel Dan Y. , Awawdeh Fakhri B. , Hazama Ali
Published: January 2024

Background:

Calcium pyrophosphate deposition disease (CPPD), also known as “pseudogout,” is a crystal deposition arthropathy involving the synovial and periarticular tissues. Pseudogout rarely presents in the axial spine. Here, we present the case of an 80-year-old female patient admitted after a mechanical fall, initially misdiagnosed on computed tomography (CT)/magnetic resonance studies with cervical osteodiscitis/ventral epidural abscess that proved to be pseudogout.

Case Description:

An 80-year-old female was admitted after a mechanical fall. The initial cervical CT scan showed multilevel degenerative changes with an acute C6 anterior wedge compression fracture, focal kyphosis, C5-6 disc space collapse, and endplate destruction. The magnetic resonance imaging showed marked contrast enhancement of the C5-6 vertebral bodies and disc space. An interventional radiology-guided biopsy of the C5-6 vertebral bodies and disc space was consistent with calcium pyrophosphate deposits, was diagnostic for pseudogout, and was negative for infection. She was managed conservatively with a rigid collar and seven days of oral prednisone.

Conclusion:

CPPD involvement in the axial spine is rare. Prompt pathologic diagnosis should be pursued to rule out an infectious process.
Copper-Catalyzed Chemoselective (Amino)fluorosulfonylation of Hydrocarbons via Intramolecular Fluorine-atom Transfer
Authors: Qu Shuting , Li Xiao-Xi , Li Xingwei , Wang Lin
Published: January 2024

Sulfonyl fluorides have found increasing applications as functional molecules in chemistry and biology. We herein report copper-catalyzed atom-economical access to two categories of sulfonyl fluorides through a radical relay strategy in the presence of a SO2 surrogate. The aliphatic C(sp3)–H bond in N-fluoro-N-alkyl sulfonamides reacted via a 1,5-hydrogen atom transfer (HAT) process, affording alkanesulfonyl fluorides with a proximal amino group. On the other hand, utilizing substrates containing a proper C=C double bond resulted in intramolecular olefin aminofluorosulfonylation, allowing synthesis of fluorosulfonyl-functionalized pyrrolidines and piperidines via atom-transfer radical addition (ATRA). Both reaction systems proceeded under mild conditions requiring no additional fluorine source. Experimental and computational studies suggest that the S-F coupling is likely achieved through an intramolecular radical rebound pathway. By taking advantage of SuFEx chemistry and multifunctionality of the products, the method is applicable to late-stage modification of bioactive compounds, drug ligation chemistry and organic synthesis.

Authors: Ghadge Shruti , Marathe Aditya , Adivarekar Ravindra , More Sandeep
Published: January 2024

This study introduces "Woolitmus" a textile-based wearable pH indicator and sweat analyzer developed using pyranine on wool substrate. Sweat pH analysis is crucial for monitoring health conditions associated with pH imbalances. This capitalizes on pyranine's unique acid dye properties, successfully dyeing on wool fabric to create a comprehensive pH sensor. The sensor exhibits pH responsiveness under both visible and UV light, offering potential as a real-time sweat patch for pH monitoring. The process of dyeing of wool with pyranine is detailed, elucidating the mechanism behind the pH sensitivity backed up by photophysical characterizations. Stability and reversibility tests also confirm the sensor's robustness and performance. The wool fabric-based pH sensor holds promising applications, including health monitoring, disease diagnosis, and lifestyle management. The reported sensor also can simultaneously collect and detect pH levels without support of any addition accessories.

Authors: Усков Владимир Игоревич
Published: January 2024

Настоящая статья посвящена изучению задачи Коши для дифференциального уравнения второго порядка, заданного в банаховых пространствах $E_1\to E_2$ с замкнутыми линейными операторными коэффициентами, имеющими всюду плотные в $E_1$ области определения. Оператор $A$ вырожден, из-за чего решение задачи Коши существует не при каждых значениях начальных данных. Этот оператор фредгольмов с нулевым индексом (далее, фредгольмов). Его ядро полагается $n$-мерным. Свойство фредгольмовости позволяет расщепить уравнение и условия на соответствующие уравнение и условия в подпространствах уменьшающихся размерностей. В правой части операторные коэффициенты являются переменными в отличие от других работ. Исследуется случай $\Delta(t)\ne0$ при каждом $t\in[0;T]$, где $\Delta(t)$ - некоторая матрица, построенная с помощью операторных коэффициентов. Получены условия, при которых решение задачи существует, единственно; найдено это решение в аналитическом виде. Приводится иллюстрирующий пример.

This article is devoted to the study of the Cauchy problem for a second-order differential equation given in Banach spaces $E_1\to E_2$ with closed linear operator coefficients that are everywhere dense in the $E_1$ domain of definition. The operator $A$ is degenerate, which is why the solution of the Cauchy problem does not exist for every value of the initial data. This operator is Fredholm with zero index (hereinafter, Fredholm). Its kernel is assumed to be $n$-dimensional. The Fredholm property allows one to split the equation and conditions into the corresponding equations and conditions in subspaces of decreasing dimensions. On the right hand side, the operator coefficients are variable, which is different from other works. We study the case $\Delta(t)\ne0$ for each $t\in[0;T]$, where $\Delta(t)$ is some matrix constructed using operator coefficients. Conditions obtained the conditions under which the solution of the problem exists is unique; this solution is found in analytical form. An illustrative example is given.

The industrial revolution 4.0 era gives a huge challenge for higher education institutions. They are demanded to be able to produce skilled, competent, and creative graduates in competing their skill in regional, national, and international scopes. Edu-technopreneurship is an important issue necessarily conducted by higher education institutions to face this challenge. This study aimed to map a topic on edu-technopreneurship in scopus and a chance of its development in language, literature, and literacy fields. By using keywords of “education”, “technology”, and “entreprenership” in the scopus page, were found 1,383 documents discussing about these topics. These data were then analyzed quantitatively to see the developmental trend happening. Besides, a bibliometric analysis was conducted using VOS viewer to see the interrelation between documents. The result shows that studies on these topics have been frequently conducted and experiencing improvement significantly by the year. They are often related to economy, technique, technology, and education. However, they do not deal with langauge, literature, and literacy. It indicates that there is a big opportunity and challenge to study the “edu-technopreneurship” in language, literature, and literacy fields in the future.

Published: January 2024

This study aims to examine the vulnerability of primary school teachers in rural areas in conducting authentic and integrative assessments of Indonesian language learning. This research approach is a case study. The participants were 50 primary school teachers grade 5 in rural areas. Data were obtained through questionnaires, teacher-made assessment instruments, and interviews. Data were analyzed quantitatively and qualitatively. The results showed that most of the teachers did not understand the concept of authentic and integrative assessment in learning Indonesian. However, from an analysis of the assessment instrument he made, the teacher has applied the concept of authentic and integrative assessment because he copied from the teacher's book provided by the government. In practice, most teachers apply authentic and integrative assessment to receptive language skills (reading and listening), but only a small number apply them to productive skills (writing and speaking). The reason is insufficient time, the description of the score has ambiguous meaning, and the facilities at the school are not supportive. It is urgent to hold periodic training for teachers in rural areas to improve competence in assessing Indonesian subjects so that they no longer use the teacher's book as the only source of learning, including in assessment.
Virtual post-soviet space: Russian language and transnational communities
Authors: Yelenevskaya Maria , Protassova Ekaterina
Published: January 2024

This article explores linguistic and cultural ties in the informal Russian-speaking communities outside the Former Soviet Union (FSU). We employ qualitative methods, such as internet discourse monitoring, ethnographic observations, content and thematic analysis, and language assessments to examine a complex interplay between language, migration, and identity. We explore the role of a common language and cultural background in shaping the relationships and activities within the communicative sphere of Russian-speaking immigrants. The findings reveal that since the Soviet times, the FSU citizens have developed distrust of official channels and learned to rely on informal social networks. Sometimes immigrants activate their old friendships from study times, sometimes diasporans meet at language courses where they learn the local language, sometimes they get to know each other through children on the playground or during parents’ meetings at school. The virtual fora and mutual interests, aspirations for their children’s future, and attitudes toward political problems may unite or divide people who have left their home country. Overcoming difficulties of the first period of acculturation, acquiring proficiency in the local language/s, becoming familiar with the culture, and expanding social networks beyond the co-ethnics—all of these make permanent resettlement more realistic and desirable. Most often in each individual case there is a whole constellation of push factors that motivated people to migrate, and it is this constellation that distinguishes migrants from Russia and CIS countries from other groups. Although the very notion of diaspora has undergone major changes, migrants still tend to keep together with co-ethnics, at least in the first stages of life away from home. The transnational relations may be motivated by economic interests and are viewed as social capital. In many cases they are vehicles of solidarity and warmth, yet in the periods of political conflict they may also reflect distress, animosities and even mutual hate.

This research aim to describe a textological study of the issue of how the Hikayat Si Miskin manuscript text from the Harvad University - Houghton Library/ ms_Indo_18-METS collection was translated into handwritten Arabic-Malay script, the appearance of which is much different from the standard form of the letters of this script. This is the most important part in the textological study of the subfield of philology before the editing of texts from the old Malay Arabic-Malay script into Latin script is presented. His identity as the author is not included at the front of his work, but at the end of the manuscript called the colophon. The presentation of a text that has been cleaned of all writing errors paves the way for further study of the content of the text from various aspects related to the existence of the form and content of the text being studied, such as a study of the structural content of the text, a study of linguistic aspects, a study of social values. and culture, it is even possible to examine historical elements, because manuscripts are historical documents that describe the life systems and patterns of old society. The method used to discuss text issues and content that can be studied in various related scientific disciplines is the standard text criticism method, namely a philological method that attempts to re-present classical texts by criticizing and correcting corrupt texts. In accordance with the focus of the discussion which focuses on writing and visual text writing, the research results found writing irregularities and errors in writing lacunae, substitutions, additions, transpositions, dittography, and haplography. The most common writing errors are substitution errors.

Authors: Dike Ibwari Caroline , Out Mkpoikanke Sunday , Dike Adannia Amalachukwu
Published: January 2024

Purpose: The purpose of this study was to examine the effects of a hands-on educational approach on pupils' achievement and retention in the Cultural and Creative Arts.

 

Theoretical Framework: The theoretical framework for this study is based on cognitive learning and experiential learning.

 

Methodology: Study participants were primary five pupils in Oshimili South Local Government Area, Delta State. As part of this study, ten hands-on activities were used to engage primary five pupils in the learning process. Hands-on activities included magazine family puppets, musical glasses, painting to music, PVC sculptures, roll an activity, sound boxes, sound cans, sun shadow pictures, and swinging to music. Using a quasi-experimental design, two research questions and two hypotheses were developed and tested at a 0.05 level of significance. The study involved 100 primary five pupils from ten primary schools. Participants were divided into experimental and control groups (n=50). Culture and creative arts were taught through hands-on activities in the experimental group, but not to their counterparts in the control group. Despite this, after four weeks of experimentation, pretest and posttest data were collected from both groups. Data were collected using the Cultural and Creative Arts Achievement Test (CCAT) and the Cultural and Creative Arts Retention Test (CCRT). Participants were given the instruments directly by their respective group leaders. Based on the mean and standard deviation of the test scores, ANOVA was used to test the hypotheses.

 

Findings: A significant effect of hands-on instruction on pupils' achievement and retention in cultural and creative arts was found. Based on the findings, the researchers recommended that pupils should be exposed to sophisticated hands-on materials to improve their achievement and retention in cultural and creative arts, and that teachers also be trained on how to use hands-on instructions in the classroom.

 

Research, Practical & Social Implications: The study promotes active engagement and participation, which allows pupils to actively participate in the learning process. They gain a better understanding of the subject matter and retain more information. The hands-on approach promotes creativity and problem-solving skills. Pupils are encouraged to think critically, solve problems, and come up with innovative solutions through hands-on activities. As a result, their creative thinking skills are enhanced, and they are prepared for future challenges in the creative arts industry.

 

Originality/Value: In the cultural and creative arts domain, hands-on instructional methods offer originality and uniqueness. Pupils gain a deeper understanding of subjects through interactive and hands-on classroom experiences. Hands-on activities can assist teachers in creating a more engaging and effective learning environment, resulting in improved pupil performance and retention.
A NUMERICAL STUDY ON THE REDUCTION OF GREENHOUSE GASEOUS COMPONENT (CO2) DUE TO THE ADDITION OF H2 IN THE FUEL STREAM OF THE COUNTERFLOW CH4/AIR DIFFUSION FLAME
Authors: Hossain Akter
Published: January 2024

In this study, a series of 1-D and steady-state numerical simulations have been performed for the prediction of the effect of the addition of H2 on the characteristics of a non-sooting counterflow CH4/Air diffusion flame using detailed chemical reaction model, which is composed of 325 elementary chemical reactions and 53 chemical species. Under the steady-state assumption, a set of one-dimensional transport equations of mass, momentum, species, and energy along with the equation of state has been solved numerically at the atmospheric conditions over the counterflow configuration by exploiting an efficient numerical code, OPPDIF (a Fortran Program for Computing Opposed-Flow Diffusion Flames). The grid adaption technique has been used to achieve better convergence as well as to ensure the maximum accuracy of the simulated results. It is found that the flame temperature is increased due to the addition of H2 with CH4, which is injected into the fuel stream. The elevation in the temperature is caused by the augmentation of the integrated heat release rate of the elementary reactions supported by the active radicals (H, O, and OH), which are generated by the higher reactivity of H2. Besides, it is found that the mole fractions of H2O are increased as the percentage of H2 in the loading fuel (CH4) is increased and also, it is identified that the chain propagating reaction, OH + H2 => H2O + H is dominating one which produces highest amount of H2O. Furthermore, it is noticed that the indirect greenhouse gas or precursor, CO is reduced when H2 is added to CH4. Consequently, the mole fraction of the principle greenhouse gas, CO2 is decreased significantly when the fuel, CH4 percentage is modified by the higher percentage of H2. The sensitivity analysis of elementary reactions reveals the fact that the chemical reaction: OH + CO => H + CO2 is a dominating reaction in producing a lower amount of CO2 when the volume fraction of H2 is increased in the fuel (CH4) stream. In the presence of 75 % H2 in CH4, the pressure-dependent reaction, O + CO (+M) => CO2 (+M) appears as another chemical route that also generates greenhouse gas, CO2 but its contribution is negligibly small.

Achieving kinematic identity across shape diversity in musculoskeletal modeling
Authors: Sylvester Adam , Kramer Patricia
Published: January 2024

Musculoskeletal modeling is emerging as a powerful approach to investigate the locomotor biomechanics of extinct taxa. These models rely on bony morphology to define joint locations and muscle geometry. Using different motion profiles to drive models of extinct and extant taxa complicates comparisons because results reflect both morphological and kinematic differences. Here we report on an approach that permits changes in shape while maintaining model kinematics. Using a human musculoskeletal model, we carried out walking simulations of ten humans. Next, we morphed the model pelvis and proximal femur to match a reconstructed australopithecine pelvis and proximal femur. Using the kinematic results from the human walking simulations, we created new motion files based on the positions of joint centers and tracked anatomical locations. These files were used to drive simulations of the same walking trials with the australopithecine model. Joint centers and axes of the human and australopithecine models were compared for each walking trial simulation. We found that joint centers in the australopithecine simulations were typically within ~1µm of their locations in human simulations, and joint axes differed by less than 0.005 degrees. Such small differences have negligible effects on external joint moments calculated during inverse dynamics analyses. This conservative comparison will serve as a baseline for more complex simulations. Although this work focuses on one taxon, the approach outlined is applicable to a wide variety of extinct animals.

Published: January 2024

La fractura y/o fallas en los troqueles para el forjado en caliente, se debe principalmente a la fatiga térmica que se define como la aparición de grietas debido a cambios repetitivos de carga y temperatura; el motivo de este fallo es el gradiente de temperatura entre la superficie del troquel y su parte interna. En el presente estudio se lleva a cabo un análisis microscópico del inicio de microfisuras y su interacción con los óxidos de forja en un troquel de forja en caliente. Las matrices de forja en caliente analizadas corresponden a una micro - aleación H13 con vanadio. La superficie del troquel se trató térmicamente con una dureza promedio de 47 HRC y después de 12000 ciclos se retiró el troquel. La microscopia óptica se realizó con un microscopio óptico Nikon - MA 100 utilizando luz polarizada. La estéreo-microscopía se realizó con un equipo Luxeo 4D y para la medición de dureza se utilizó un equipo Dura Scan Emco-TEST. Para el análisis de microscopía electrónica de barrido, se utilizó un JEOL JSM-IT300 (3,0 nm (30 kV) 15,0 nm (1,0 kV)). Se encontró que los óxidos complejos, claramente, se forman en el area de compresión de la forja como resultado de su interacción con la atmósfera a alta temperatura (1300°C) y se comprimen durante el proceso de forja. Los óxidos corroen y degradan la superficie de la matriz cuando estos se colocan en los límites de los granos, iniciando una micro-fisura a alta temperatura.

El vapor es generado artificialmente, ya que se produce a base de agua y su cambio de estado físico, por medio de su calentamiento. Los elementos principales de este tipo de mecanismos son la caldera, el agua, un mecanismo para mover el barco, pueden ser un tipo de ruedas, paletas, hélices, etc. y obviamente el tubo hueco por el cual se libera el vapor a la atmósfera.

En el año 1787 el inventor estadounidense John Fitch construyó el primer prototipo de un barco a vapor, es decir que en este año fue inventado el barco a vapor, John Fitch al ver que el mecanismo a vapor en los ferrocarriles funcionaba de una forma muy buena, casi perfecta, decidió intentar crear un mecanismo similar pero ahora en un transporte marítimo. Al trabajar en su invento se percató que estos barcos eran más rápidos que los tradicionales. Los barcos a vapor nos ayudarían años después a transportar ciertas mercancías de un continente a otro de manera más rápida, eficiente y económica. Actualmente muchas empresas transnacionales transportan sus productos por medio de los barcos a vapor.
Bajo el signo del Grial, un mito de redención
Authors: Aranda Espinosa Francisco
Published: January 2024

El mito del Santo Grial se ha asociado, normalmente, a la búsqueda, a la espiritualidad, a la salvación; en una palabra: a la redención. Lo que no podemos, sin embargo, afirmar desde ahora es que se trate de una redención física o espiritual ¿O ambas? Lo que aquí nos proponemos hacer es, aunque de un modo un tanto vertiginoso, buscar sus orígenes, algunos aspectos de la hermenéutica simbólica que ha surgido a partir de la especulación del tema, resumir dos de sus versiones literarias y una operística, y bordear su esencia fenoménica desde una lectura de corte psicoanalítico. Y, en la búsqueda del mito del Grial es probable que demos con nuestro Grial.
Reivindicación de la subjetividad sensorial ante la inteligencia artificial en la creación artística
Authors: Bracamonte Ocaña Mario Alberto
Published: January 2024

En este ensayo se demuestra que el arte que se produce usando inteligencia artificial es una falacia tecnológica ya que no puede superar, hasta el momento, las condiciones fenomenológicas del cuerpo - sujeto y como unidad. Esta, es detonante y parte fundamental de la producción artística, además los artistas robots y las páginas web donde se produce AI Art, tampoco han superado los desplazamientos epistémicos que los artistas llevan desarrollando desde la aparición de las vanguardias. Se discuten los conceptos de conciencia artificial y auto conciencia en referencia a la fenomenología de Maurice Merleau – Ponty. Por último, se concluye cómo estas características del arte actual están reconfigurando al arte posmoderno derivando en un arte post- contemporáneo

En la ciudad de Sevilla se realizan procesiones religiosas durante todo el año con altares que literalmente caminan por la calle, llevados a paso lento por hombres que los cargan. Éstas son organizadas por asociaciones llamadas hermandades. Las procesiones han tenido lugar en Sevilla desde al menos el siglo XVII. En el siglo XXI se han multiplicado, y ahora cientos de ellas tienen lugar. Los sentimientos que provocan estas procesiones tanto en quienes desfilan como entre quienes las presencian suele llevar a muchas personas a la exaltación emocional. Esto se debe, en parte, a que cada procesión se caracteriza por un asalto total a los sentidos: Los espectáculos visuales, las experiencias táctiles, los sonidos y olores que rodean a cada procesión crean una atmósfera sensorial compleja que asombra a propios y extraños. Extendiendo el concepto de marca originalmente usado por Murray Shafer (1977) para hablar de marcas sonoras (soundmarks), a otros campos sensoriales, muestro cómo diversas procesiones sevillanas crean sus propias marcas sensoriales, en las que el incienso ahora juega un papel protagónico.
Botanas Saludables Elaboradas con Harina Libre de Gluten
Authors: Medina-Pérez Gabriela , Cruz-Cadena Adriana , Perez-Soto Elizabeth , Choque-Rivera Tania J. , Almendares-Calderón Laura
Published: January 2024

En México las botanas que más se consumen son de maíz, cacahuate y papa, generalmente como frituras, sin embargo, existe gran disponibilidad de otros tubérculos que pueden ser utilizados para elaborar este tipo de productos obteniendo una textura y sabor similar, pero con mejores características nutricionales con un aporte calórico bajo.

Las ventajas de las botanas saludables contra los convencionales, son que tienen la reducción de sodio, grasa y azúcar, además se eliminan las grasas trans, mejorando los beneficios de todos los ingredientes naturales para que sean funcionales y no solo sean “saludables”, son más nutritivos, balanceados, elaborados con ingredientes no convencionales que pueden ser atrayentes para el consumidor que se adaptan a sus necesidades y gustos.
Generación de imágenes médicas en el área de la retinopatía diabética con ayuda de redes generativas antagónicas

Published: January 2024

Una de las enfermedades que más afectan al sistema visual humano es la Retinopatía Diabética (RD), siendo esta una de las principales causas de ceguera a nivel mundial. Esta enfermedad se deriva de la Diabetes. Es importante que los oftalmólogos puedan detectar esta enfermedad a tiempo para poder darle un tratamiento adecuado. Se han propuesto trabajos de detección del grado de RD y detecciones de lesiones provocadas por la RD. Para mejorar la precisión de estos algoritmos es necesario entrenarlos de una manera correcta con una basta base de datos segmentada. A la fecha las bases de datos existentes en la RD contienen un número limitado de imágenes. Por lo cual se propone incrementar el número de imágenes de RD con ayuda de SinGAN (Aprendizaje de un modelo generativo a partir de una sola imagen natural) con esta red es posible crear nuevas imágenes a partir del entrenamiento de una sola imagen.

Validation of the health belief model scale for generalized anxiety in Mexican adult of general population
Authors: Bernal-Avila Samantha , Gil-Bernal Flor M. E.
Published: January 2024

According to the literature review, there are theoretical models that explain the presence of anxiety in people. These explanations agree that beliefs regarding control and the perception of vulnerability to worry seem to play an important role in the onset and maintenance of generalized anxiety disorder (GAD). Perceiving oneself capable of modifying these concerns facilitates change and taking action in the face of worrying situations in everyday life. The Health Belief Model (HBM) has been one of the most widely used conceptual frameworks to explain the change and maintenance of behaviors related to different health situations and to develop scales that allow identifying beliefs related to the problem in question, however , there are no scales based on this model for generalized anxiety, so the purpose of this research was the construction and validation of a scale with these characteristics. The construction of the items was carried out based on the dimensions that make up the HBM and subsequently validation by judges was carried out. Scales of anxiety, depression, life satisfaction, and self-efficacy were applied to establish the convergent and discriminant validity of the scale. Finally, an Exploratory Factor Analysis was carried out, from which 24 Likert-type scale items were obtained that were grouped into 5 dimensions, explaining 58.6% of the total variance and with a total Cronbach's alpha of .803.
