‘Una persona dependente alla Serenissima Gran Duchessa’ : Female Embroiderers and Lacemakers between the courts of Florence and France
Authors: Modesti Adelina
Published: September 2021

Adelina Modesti reconstructs the experiences of Caterina Angiola Pieroncini
and ‘La Trottolina’, two embroiderers and lacemakers in the 1660s. Both were
ladies-in-waiting to Grand Duchess Vittoria della Rovere, an important patron
of women artists and artisans at the Medici Court. The Grand Duchess provided
training and education to both women, sending them to Paris to perfect their
needlework skills in the new French styles. Having gained proficiency in France,
both women were repatriated to Florence, where they continued in service to
the Grand Duchess, alongside other ladies who had been trained in lacemaking
at local convents. All these women were dependent on the protection of their
patron, who did not fail to provide morally and materially for her young charges.
Stuck on the side of the road
Authors: Murton Galen , Sigdel Tulasi Sharan
Published: September 2021

This chapter examines rural road development in Nepal to understand
how the purported benefits of new transport mobilities in fact reinforce
longstanding social hierarchies, create conditions for the consolidation
of centralized elite power and capital accumulation, and reproduce terms
of marginality and precarity for vulnerable populations in highland
Nepal. The authors posit that road development in Nepal functions as a
‘liberal mode of governance’ (Duffield 2008) whereby both private and
public actors territorialize national space and articulate a new but still
uneven future for Nepal. More broadly, this chapter aims to illuminate
how non-state actors working in peripheral and rural regions – such as
transport syndicates and development contractors in Nepal – help to
materialize the capitalist and bureaucratic objectives of central state
authorities through liberal practices of infrastructure development.
The edge of Kaladan
Authors: Sarma Jasnea
Published: September 2021

Using the case of India’s mega-infrastructure build-up, the Kaladan
Multimodal Transport Project (KMMTP) in the ‘remote’ and ethnically
contentious borderlands between India and Myanmar, this chapter takes
an ethnographic approach to understand the meaning of spectacular
connectivity and infrastructure on remote borderlands. Based on six
months of fieldwork, the chapter explores the voices, visions, spatial
and ethnic worlds of border residents who subsequently have to position
themselves and their remoteness to absorb the Indian state’s spectacular
new connective infrastructure. The chapter narratively traverses along this
newly constructed road, to the very edge of a hitherto informal and flexible
border with Myanmar. In doing so, it highlights the need to investigate the
banal, unspectacular and interethnic lived realities of the borderland. The
chapter argues that spectacular infrastructures such as the KMMTP are
harnessed in the pursuit of territorial control, making the remote legible
and for extracting profits. The chapter introduces the analytic of the
‘spectacle’ to demonstrate how powerful states and ethnic communities
rely on grand infrastructural spectacles and cross-border projects often at
the expense, erasure and displacement of those at the edge of borderlands,
who have the least stake in shaping such spectacular infrastructures.

Authors: Shrivastava Prashant Kumar , Sharma Mayank , Kamble Megha , Gore Vaibhav
Published: September 2021

The quick access to information on social media networks as well as its exponential rise also made it difficult to distinguish among fake information or real information. The fast dissemination by way of sharing has enhanced its falsification exponentially. It is also important for the credibility of social media networks to avoid the spread of fake information. So it is emerging research challenge to automatically check for misstatement of information through its source, content, or publisher and prevent the unauthenticated sources from spreading rumours. This paper demonstrates an artificial intelligence based approach for the identification of the false statements made by social network entities. Two variants of Deep neural networks are being applied to evalues datasets and analyse for fake news presence. The implementation setup produced maximum extent 99% classification accuracy, when dataset is tested for binary (true or false) labeling with multiple epochs.
Visualizing the Impact of Home Advantage in National Basketball Association-NBA
Authors: Singh Abrol Ekas , Lamba Puneet Singh , Jain Achin
Published: September 2021

In sports, home advantage describes the benefits that the home team enjoys over the away team. These benefits are manifested due to cognitive effects that the local home crowd may have over the competitors or umpires, advantages of playing in familiar situations resulting in better adaptability, specific rules favouring the home team directly or indirectly, the away teams often suffer from jet lag due to change in time zones or from the tenacity of travel, etc. In this paper, various exploratory data visualization techniques have been utilized to observe the impact of home advantage in professional basketball association league NBA- National Basketball Association. Further the factors attributing to home advantage in sports are analysed. It was observed that when the team had performed well at home games, the results reflected the same for away games; however, home advantage was still distinctively visible.
Anomaly Detection in Arabic Texts using Ngrams and Self Organizing Maps
Authors: Almarimi Abdulwahed , Salem Asmaa
Published: September 2021

Every written text in any language has one author or more authors (authors have their individual sublanguage). An analysis of text if authors are not known could be done using methods of data analysis, data mining, and structural analysis. In this paper, two methods are described for anomaly detections: ngrams method and a system of Self-Organizing Maps working on sequences built from a text. there are analyzed and compared results of usable methods for discrepancies detection based on character n-gram profiles (the set of character n-gram normalized frequencies of a text) for Arabic texts. Arabic texts were analyzed from many statistical characteristics point of view. We applied some heuristics for measurements of text parts dissimilarities. We evaluate some Arabic texts and show its parts they contain discrepancies and they need some following analysis for anomaly detection. The analysis depends on selected parameters prepared in xperiments. The system is trained to input sequences after which it determines text parts with anomalies using a cumulative error and winner analysis in the networks. Both methods have been tested on Arabic texts and they have a perspective contribution to text analysis.
Audio Cryptography via Enhanced Genetic Algorithm
Authors: Alhassan Salamudeen , Kofi Armah Gabriel , Zabsonre Alhassan Issah
Published: September 2021

As communication technologies surged recently, the secrecy of shared information between communication parts has gained tremendous attention. Many Cryptographic techniques have been proposed/implemented to secure multimedia data and to allay public fears during communication. This paper expands the scope of audio data security via an enhanced genetic algorithm. Here, each individual (audio sample) is genetically engineered to produce new individuals. The enciphering process of the proposed technology acquires, conditions, and transforms each audio sample into bit strings. Bits fission, switching, mutation, fusion, and deconditioning operations are then applied to yield cipher audio signals. The original audio sample is recovered at the receiver's end through a deciphering process without the loss of any inherent message. The novelty of the proposed technique resides in the integration of fission and fusion into the traditional genetic algorithm operators and the use of a single (rather than two) individual(s) for reproduction. The effectiveness of the proposed cryptosystem is demonstrated through simulations and performance analyses.
Challenges for Managing Complex Application Portfolios: A Case Study of South Australian Public Sector Agency
Authors: Mirza Yaser
Published: September 2021

This research explores the challenges in management and the root cause for complex application portfolios in the public sector. It takes Australian public sector organisations with the case of South Australia Police (SAPOL) for evaluation it being one of the significant and mission critical state government agencies. The exploratory research surfaces some of the key challenges using interview as primary data collection source, along with archive records, documentation, and direct observation as secondary sources. This paper reports on the information analysed surfacing eight key issues. It highlights that the organic growth of the technology portfolios, with mission criticality has resulted in many quick fixes which are not aligned with long term enterprise architectural stability. Integration of different mismatched technologies, along with the pressure from the business to always keep the lights on, does not provide the opportunity for the portfolios to be rationalised in an ongoing way. Other issues and the areas for further study are explored at the end.
A Review on Classification of Data Imbalance using BigData
Authors: Ramasubramanian  , Shanmugasundaram Hariharan
Published: September 2021

Classification is one among the data mining function that assigns items in a collection to target categories or collection of data to provide more accurate predictions and analysis. Classification using supervised learning method aims to identify the category of the class to which a new data will fall under. With the advancement of technology and increase in the generation of real-time data from various sources like Internet, IoT and Social media it needs more processing and challenging. One such challenge in processing is data imbalance. In the imbalanced dataset, majority classes dominate over minority classes causing the machine learning classifiers to be more biased towards majority classes and also most classification algorithm predicts all the test data with majority classes. In this paper, the author analysis the data imbalance models using big data and classification algorithm.
Domain based Chunking
Authors: Mohapatra Nilamadhaba , Sarraf Namrata , Sahu Swapna sarit
Published: September 2021

Chunking means splitting the sentences into tokens and then grouping them in a meaningful way. When it comes to high-performance chunking systems, transformer models have proved to be the state of the art benchmarks. To perform chunking as a task it requires a large-scale high quality annotated corpus where each token is attached with a particular tag similar as that of Named Entity Recognition Tasks. Later these tags are used in conjunction with pointer frameworks to find the final chunk. To solve this for a specific domain problem, it becomes a highly costly affair in terms of time and resources to manually annotate and produce a large-high-quality training set. When the domain is specific and diverse, then cold starting becomes even more difficult because of the expected large number of manually annotated queries to cover all aspects. To overcome the problem, we applied a grammar-based text generation mechanism where instead of annotating a sentence we annotate using grammar templates. We defined various templates corresponding to different grammar rules. To create a sentence we used these templates along with the rules where symbol or terminal values were chosen from the domain data catalog. It helped us to create a large number of annotated queries. These annotated queries were used for training the machine learning model using an ensemble transformer-based deep neural network model [24.] We found that grammar-based annotation was useful to solve domain-based chunks in input query sentences without any manual annotation where it was found to achieve a classification F1 score of 96.97% in classifying the tokens for the out of template queries.
Electronic Devices as Correlates of Sedentary Behavior and Screen Time Among Diverse Low-Income Adolescents During the School Year and Summer Time
Authors: Sallis James , Conway Terry L , Cain Kelli L , Geremia Carrie , Bonilla Edith , Spoon Chad
Published: September 2021

Excessive screen time among adolescents increases risk for overweight/obesity. Having electronic devices in the adolescent’s bedroom is associated with more screen time. The present study expanded on previous studies by also examining portable personal electronic devices and social media membership as correlates of screen time use and total sedentary time in the school year and summer among diverse low-income adolescents. Adolescents aged 10-17 years were recruited from lower-income areas, and n=150 completed surveys and wore accelerometers in both the school year and summer: 34 African Americans, 23 American Indians, 16 Asian/Pacific Islanders, 39 Latinos, and 38 White/non-Hispanics. Total sedentary time was computed from accelerometers. Recreational screen time was assessed with a 3-item validated scale. Adolescents reported the presence of 6 electronic devices in their bedrooms, ownership of 4 portable devices, and social media membership. General linear modeling was conducted for both time periods, with demographic covariates and interactions with sex and race-ethnicity. More electronic devices in bedrooms were related to more screen time during the school year and summer, and to more total sedentary time in summer. Personal electronics were only related to more screen time in the school year. Social media membership was related to more total sedentary time in summer, but only among African Americans, American Indians, and non-Hispanic Whites. Electronic devices in bedrooms was confirmed as a risk factor for sedentary behavior among low-income adolescents of color. Social media membership and use should be further studied with diverse adolescents.

Published: September 2021

Disparities in youth obesity continue despite an increasing number of programs designed to combat this challenge. Policy, systems, and environmental (PSE) changes hold promise for these populations. This study identifies lessons from adult leaders for youth advocacy programs. Youth Engagement & Action for Health! (YEAH!) is a youth advocacy curriculum for PSE change that promotes healthy behaviors. From 2017-2019, 18 youth-serving organizations recruited 11-14 year olds from low-income urban, suburban, and rural areas. 237 participants in 19 youth groups completed YEAH! with 28 adult leaders.  YEAH! adult leaders completed pre- and post-surveys on adult leader characteristics, group structure and dynamics, barriers to success, and technical assistance needs.  Researchers interviewed adult leaders at the completion of each YEAH! project. This community based participatory research (CBPR) project engaged adult leaders to collect data, analyze coded transcripts and interpret results. Clubs evaluated with positive outcomes were facilitated by adult leaders who had previous engagement with the youth, showed enthusiasm for youth advocacy, and had access to resources to motivate group cohesion, participation, and commitment. The adult leader steering committee synthesized the findings into a set of best practices and strategies to help group leaders be as successful as possible when leading future youth advocacy groups.
Canadians and the Founding of the Society for American Archaeology (1934–1940s)
Authors: Kapches Mima Brown
Published: September 2021

In December of 1934 the Society for American Archaeology was officially constituted. In 1935, in an effort to grow the membership, professional archaeologists were asked to propose members who they endorsed to become affiliated with the SAA. The two professional archaeologists in Canada at that time, Diamond Jenness and William J. Wintemberg of the Dominion Museum, Ottawa, proposed names of individuals across Canada who were collectors, museum curators, and historians. A small number suggested for membership joined, but most did not. This was an interesting period in North American archaeology as professionals worked in committees to establish cultural and temporal frameworks of the archaeological past, establish excavation guidelines, and lobby against the sale of antiquities. Some Canadian avocationals who joined were positively impacted by their association with American archaeologists and their legacies continue through to today. The bottom line is that there were very few professional archaeologists in Canada following Wintemberg’s death in 1941, and that lack coupled with WWII, meant that Canadians looking for professional support and guidance looked to the south of the border. The Society for American Archaeology was important for the growth and development of Canadian archaeology during this time.
Situating Copper Crescents
Authors: Cipolla Craig N.
Published: September 2021

This report considers copper crescent-shaped objects from Ontario, contextualizing them within broader archaeological discussions of the Old Copper Complex. I focus on a small assemblage of antiquarian-collected crescents from the Royal Ontario Museum. A literature review comprises the bulk of this report; crescents recovered from sites located in the center of the Old Copper Complex, in current-day Wisconsin and Michigan, help to situate examples in the antiquarian collection. I discuss crescents in terms of their chronological and geographic breadth, their formal variation, and the different depositional contexts in which they are found. Three examples from the antiquarian collection represent novel forms of copper crescent that are not represented in the accepted typology. Two of these, collected approximately 1,600 km apart from one another, closely resemble stone and copper ulu knives, each with a unique copper handle that once bore a haft. By situating this particular collection within broader discussions of native copper, this report demonstrates the continued importance of thinking through poorly-contextualized archaeological collections while remembering the limitations of rigid, typological thinking.
The creation of a multi-cultural identity for window displays in Durban's fashion retail shop fronts
Authors:   , Lichkus Sarah Christine
Published: September 2021

The purpose of this study was to explore the possibility of creating shop window displays focussing on a South African identity in the Durban region. The impetus for the study stemmed from the design of the Constitutional Court which features elements of South African culture. This study challenges the contemporary notion of presenting window displays using primarily Western influences and proposes the use of fashion imagery and cultural identity currently dominating South Africa. The study argues against corporate fashion stereotypes and champions a representation of an eclectic multi-cultural South African society. In this respect key theories of identity, culture, and design were explored. A qualitative methodology was conducted utilising interview and observation approaches to obtain data. Semi-structured interviews were conducted with twelve local professionals specialising in the fields of art, design, fashion and architecture to obtain their expert opinions. The data was analysed by clustering information into themes to establish the findings. Interview findings revealed that shop window displays should accommodate local imagery appropriate to the South African context. Observing two local production houses, namely Hirt & Carter and Barrows in Durban provided insights for a backdrop creation for the practical component of the study. The practical comprised of producing retail shop installations and a visual catalogue representing findings drawn from the study. The catalogue was used to illustrate the results of investigating a national image and identity that could be intrinsic to window display creation in South African fashion retail shop fronts.

Development of a laser-photofragmentation laser-induced fluorescence instrument for the detection of nitrous acid and hydroxyl radicals in the atmosphere
Authors: Bottorff Brandon , Reidy Emily , Mielke Levi , Dusanter Sebastien , Stevens Philip S.
Published: September 2021

Abstract. A new instrument for the measurement of atmospheric
nitrous acid (HONO) and hydroxyl radicals (OH) has been developed using
laser photofragmentation (LP) of HONO at 355 nm after expansion into a
low-pressure cell, followed by resonant laser-induced fluorescence (LIF) of
the resulting OH radical fragment at 308 nm similar to the fluorescence
assay by gas expansion technique (FAGE). The LP/LIF instrument is calibrated
by determining the photofragmentation efficiency of HONO and
calibrating the instrument sensitivity for detection of the OH fragment. In
this method, a known concentration of OH from the photo-dissociation of
water vapor is titrated with nitric oxide to produce a known concentration
of HONO. Measurement of the concentration of the OH radical fragment
relative to the concentration of HONO provides a measurement of the
photofragmentation efficiency. The LP/LIF instrument has demonstrated a
1σ detection limit for HONO of 9 ppt for a 10 min integration time.
Ambient measurements of HONO and OH from a forested environment and an urban
setting are presented along with indoor measurements to demonstrate the
performance of the instrument.

Abstract. The TOPAS (Tikhonov regularised Ozone Profile retrievAl with SCIATRAN) algorithm to retrieve vertical profiles of ozone from space-borne observations in nadir-viewing geometry has been developed at the Institute of Environmental Physics (IUP) of the University of Bremen and applied to the TROPOspheric Monitoring Instrument (TROPOMI) L1B spectral data version 2. Spectral data between 270 and 329 nm are used for the retrieval. A recalibration of the measured radiances is done using ozone profiles from MLS/Aura. Studies with synthetic spectra show that individual profiles in the stratosphere can be retrieved with an uncertainty of about 10 %. In the troposphere, the retrieval errors are larger depending on the a priori profile used. The vertical resolution above 18 km is about 6–10 km, and it degrades to 15–25 km below. The vertical resolution in the troposphere is strongly dependent on the solar zenith angle (SZA).
The ozone profiles retrieved from TROPOMI with the TOPAS algorithm were validated using data from ozonesondes and stratospheric ozone lidars. Above 18 km, the comparison with sondes shows excellent agreement within less than ±5 % for all latitudes. The standard deviation of mean differences is about 10 %. Below 18 km, the relative mean deviation in the tropics and northern latitudes is still quite good, remaining within ±20 %. At southern latitudes, larger differences of up to +40 % occur between 10 and 15 km. The standard deviation is about 50 % between 7–18 km and about 25 % below 7 km. The validation of stratospheric ozone profiles with ground-based lidar measurements also shows very good agreement. The relative mean deviation is below ±5 % between 18–45 km, with a standard deviation of 10 %.
TOPAS retrieval results for 1 d of TROPOMI observations were compared to ozone profiles from the Microwave Limb Sounder (MLS) on the Aura satellite and the Ozone Mapping and Profiler Suite Limb Profiler (OMPS-LP). The relative mean difference was found to be largely below ±5 % between 20–50 km, except at very high latitudes.
Sequential data assimilation for real-time probabilistic flood inundation mapping
Authors: Jafarzadegan Keighobad , Abbaszadeh Peyman , Moradkhani Hamid
Published: September 2021

Abstract. Real-time probabilistic flood inundation mapping is crucial for flood risk warning and decision-making during the emergency period before an upcoming flood event. Considering the high uncertainties involved in the modeling of a nonlinear and complex flood event, providing a deterministic flood inundation map can be erroneous and misleading for reliable and timely decision-making. The conventional flood hazard maps provided for different return periods cannot also represent the actual dynamics of flooding rivers. Therefore, a real-time modeling framework that forecasts the inundation areas before the onset of an upcoming flood is of paramount importance. Sequential data assimilation (DA) techniques are well known for real-time operation of physical models while accounting for existing uncertainties. In this study, we present a DA hydrodynamic modeling framework where multiple gauge observations are integrated into the LISFLOOD-FP model to improve its performance. This study utilizes the ensemble Kalman filter (EnKF) in a multivariate fashion for dual estimation of model state variables and parameters where the correlations among point source observations are taken into account. First, a synthetic experiment is designed to assess the performance of the proposed approach; then the method is used to simulate the Hurricane Harvey flood in 2017. Our results indicate that the multivariate assimilation of point source observations into hydrodynamic models can improve the accuracy and reliability of probabilistic flood inundation mapping by 5 %–7 %, while it also provides the basis for sequential updating and real-time flood inundation mapping.

Authors: Smadi Leena , Kharma Lara , Abu Abed Asma’a , Bny Mfarej Eman , Abdalmohdi Asma
Published: September 2021

Objectives: Calculate the prevalence and severity of dental caries and periodontal health among school students aged 12-18 years old and their attitudes toward dental health and oral hygiene at Al-Mafraq governate- Jordan.Materials and methods: Demographic and oral behavioral information were collected; students aged 12-18 years old from six public schools distributed over three districts in Al-Mafraq governate over a six-month period had a full oral and dental examination. DMFT index (Decay, Missing, Filling, Teeth) was used to measure caries experience. Plaque index (PI) and gingival index (GI) of Löe and Silness were used to evaluate the oral health status. T - test was used for statistical evaluation. A P-value < 0.05 was considered statistically significant.Results: 1165 students were examined, 51% never had been to a dentist or had any previous dental treatment, 39.6% of the students examined never brushed their teeth and 61.85 % had dental caries. The (SiC) was 4.72 with a decay representing 93.53%. Females brush their teeth more frequent than males with a statistically significant difference; p< 0.001. Females showed lower DMFT index (1.81) and compared to males (2.25) with a statistically significant difference. Females showed lower SiC (4.164) compared to males (5.186)   with a statistically significant difference. There was no statistically significant difference between males and females in PI p= 0.590, and GI; p= 0.852.Conclusions: The prevalence of dental caries among students in Al-Mafraq governate and the significant caries index were substantially higher than the target goals of WHO/ FDA of year 2015 with more than 90 % of unmet treatment needs. Girls showed better oral hygiene habits compared to boys and exhibited less dental caries experience. However, periodontal status did not differ significantly between both genders.

Aim: Evaluation of stresses induced on over-denture abutments endodonticaly treated with two different obturation techniques.Materials and methods: eight mandibular permanent canines were inserted in four pesudo-realistic models.  In each model two canines were placed in it. One canine was treated with lateral obturation technique and the other canine with vertical obturation technique. Four over-denture prostheses were fabricated on the four models. Then strain gauges were attached on the coronal one third of the root buccally and lingually for all eight canines. A metal rod was placed occlusally on the premolar –molar area, and a 50 N load was applied on the middle of the rod using the universal testing machine. Readings were collected. Results: from the collected data the lateral obturation showed 85.25±104.901 µε and the vertical obturation showed 4.875±3.555 µε with significance difference of P<0.05 between the groups.Conclusion: it can be concluded that the abutments treated with vertical obturation techniques reduced the stresses induced to the supporting structures when compared with the lateral condensation technique.
Do different time intervals in placement of restorative materials over calcium silicate cements, affect interface microhardness of different restorative materials?
Authors: Bolhari Behnam , Meraji Naghmeh , Khazaee Pegah , Ghabraei Sholeh , Valizadeh Sara
Published: September 2021

Objectives: The type of materials and application time of final restorations on calcium silicate cements (CSCs) are important factors which influence the interfacial properties. The aim of this study was to investigate the effect of different placement time of RMGI (Resin Modified Glass Ionomer), composite resin and amalgam over different CSCs on the surface microhardness of these restorative materials.Methods: Each CSCs material (Biodentine, MTA, CEM cement) was mixed and carried into a hole (6mm diameter ×4 mm thickness) in the center of 270 molds (n=90 /each CSC). Then these molds were randomly divided into three main experimental groups (n=30) in regard of restorative materials (Amalgam, RMGI, Composite) that were placed in the other molds with the same hole size to make restorative materials and CSCs in contact together. Afterwards, each experimental group was divided into three subgroups according to the time interval of restoration placement that was immediately, after 24h and after 72h (n=10). Two molds were separated from each other after one week storage in incubator with 100% humidity in 37 °C, in order to evaluate the Vickers microhardness of restorative materials in CSC-restorative material interface. Statistical analysis included two-way Anova followed by Post hoc Dunnett T3 in cases with lack of homogeneity and Tukey HSD in cases with homogeneity.(p=0.05)Results: The microhardness of all restorative materials was neither significantly influenced by the CSCs materials (p>0.05) nor by the timing of final restoration (p>0.05) except in RMGI in immediate contact with CEM cement. (p<0.001)Conclusion: Restorative materials hardness in interface with studied CSCs may not affect. This in vitro study found no evidence against immediate deﬁnitive restoration over CSCs.

The fast elevation of the salivary pH in orthodontic patients has acritical role to safe the teeth and encourage the orthodontic treatment after acidic challenger. As their baseline salivary pH is dropped during fixed orthodontic treatments.Aims: this study was aimed to evaluate the durability of three types of mouthwashes on the salivary buffering capacity in orthodontic patients at 0, 5, 10, 15 mints after acidic challenger using direct pH meter.Material and method: 80 orthodontic patients; age range (13-21years) were distributed into four groups; 20/ each, the salivary pH were recorded using compact pH meter (LAQUAtwin, HORIBA's, Kyoto, Japan) before and after administration of carbonated beverage (100 mm coca cola) and directly after gargling with 100 ml of the tested mouthwashes (herbal, green tea and chlorohexidine mouthwash) beside tap water as placebo control. The pH was documented again at 0, 5, 10 and 15 mins after each mouthwash gargling. One way ANOVA analysis and Duncan multiple were used for salivary pH analysis, p≤0.05.Results: non-significant differences were found at 0, 5, 10, 15 mints in comparison with baseline pH after herbal mouthwash gargling, the same result was shown with chlorohexidine mouth wash but with less defined border. Salivary pH after green tea gargling showed clear oscillatory results after the same tested periods.Conclusions: Herbal mouthwash is the best type to improve salivary pH for longer duration after acidic challenger. While Chlorohexidine mouthwash shows beneficial effects in elevation salivary pH with less duration. Green tea mouthwash fail to control salivary pH for long duration.

Published: September 2021

Memoria, creatividad e imagen emergen como tres factores culturales clave en la historia y el devenir de las civilizaciones. La memoria, extraordinario almacén de experiencias y conocimientos, es instrumento imprescindible en los procesos de creación y resolución de problemas. A menudo, vinculada en exclusividad al pasado, la memoria actúa en el presente y, su potencial valor de proyección, la hace imprescindible en el futuro. En la memoria, la imagen ocupa un lugar destacado, tanto en su dimensión sensorial como en su dimensión mental. El sujeto construye y perfecciona conceptos (imágenes mentales) que le empujan a comportarse de un determinado modo, e imagina, creando imágenes fantásticas, a menudo, a partir de sus recuerdos. El objetivo principal de este artículo es estudiar las conexiones entre memoria, creatividad e imagen para alcanzar un conocimiento más profundo que permita reflexionar sobre tales interacciones y sus oportunidades. Para ello, se plantea una metodología epistemológica coherente y unitaria con enfoque fenomenológico que explica la complejidad de las interrelaciones y la esencia de los tres factores, estudiados en cuanto a fenómenos vitales. Finalmente, se propone una red semántica de todas las interacciones encontradas, abriendo las puertas a investigaciones posteriores.
Diagrama, clichés y algoritmos: una aproximación a la visión maquínica desde la perspectiva no-representacional de Gilles Deleuze
Authors: Celis Bueno Claudio , Schultz María Jesús
Published: September 2021

El presenta artículo examina la obra El sueño neoliberal (2015) del artista visual chileno Felipe Rivas San Martín a través del concepto de diagrama propuesto por Gilles Deleuze. La obra de Rivas San Martín somete la conocida imagen del bombardeo a La Moneda el 11 de septiembre de 1973 a una interpretación iterativa por parte del algoritmo Deep Dream de Google. Al leer esta operación desde el concepto de diagrama de Deleuze se nos hacen visibles las relaciones de fuerza que atraviesan a ambas imágenes. Esto permite una reflexión sobre el tipo de operaciones que caracterizan al algoritmo de Google. El artículo ofrece dos hipótesis principales. En primer lugar, sugiere que el sistema trazo/mancha propuesto por Deleuze para caracterizar el diagrama permite visualizar las fuerzas interpretativas que están en juego en la operación de Rivas San Martín y que guían la interpretación algorítmica de Deep Dream. En segundo lugar, se sugiere que el algoritmo, por un lado, desarticula los clichés anquilosados en la imagen original (deshaciendo tanto su dimensión simbólica como figurativa), pero por el otro vuelve a imponer nuevos clichés contenidos en las bases de datos utilizadas para su entrenamiento. Estos clichés, sin embargo, no pueden retornar más que de forma monstruosa.

Este artículo aborda el uso de las prácticas artísticas contemporáneas cómo vehículo de experimentación y expresión con un grupo de adultos con discapacidad intelectual. A través de un estudio de caso, basado en la observación participante, se analizan los retos de la utilización de las denominadas “estrategias de pensamiento visual” (Yenawine, 2013) un método que facilita el diálogo sobre las obras y la creación de significados colectivos. Del análisis de los resultados se desprende que dichas estrategias permiten generar un espacio de comunicación y reflexión en el colectivo de personas con discapacidad, no requiriéndose más adaptaciones que aquellas necesarias para superar barreras físicas. Se observó el deseo y la satisfacción de implicarse a la hora de crear ficciones colectivas basadas en experiencias personales. Destaca el papel motivador de algunos medios, como el vídeo o la fotografía que han puesto de manifiesto las posibilidades de las prácticas artísticas como herramienta de discusión a través del debate y de la creación colectiva.
Más allá del arte: encuentros con fotógrafos en torno a la naturaleza
Authors: Blanco Arroyo María Antonia
Published: September 2021

¿Qué hay detrás del pensamiento artístico? La siguiente propuesta plantea una aproximación al mundo de la fotografía en base a la experiencia de una serie de encuentros con artistas durante una estancia en la Universidad de California, Berkeley. No hay nada mejor para responder a preguntas complejas que abordarlas desde un punto de vista multifocal, y la colaboración con varios fotógrafos estadounidenses nos ayuda a establecer formas de mirar que van incluso más allá del arte. Con este estudio queremos dar testimonio de la investigación artística desarrollada en los encuentros y visitas a estudios de fotógrafos americanos que nos abrieron las puertas para compartir su particular visión de la naturaleza y de la transformación del mundo en cada una de sus fotografías, revelándonos nuevas soluciones en la proyección y producción de obras. El recorrido de estos encuentros nos lleva a explorar el mundo de los fotógrafos Peter Goin, Stephen Galloway, Jack Fulton y Richard Misrach, cuyos modos de ver y construir la imagen se proyecta mediante una variada metodología de trabajo que fluctúa entre la invención y la documentación. Sin olvidar la humanidad implícita en sus palabras y acciones.
La Educación Artística ante el reto de enseñar a aprender: un estudio de caso en la formación de docentes
Authors: Salido López Pedro V.
Published: September 2021

El modelo de aprendizaje competencial que de un tiempo a esta parte caracteriza al sistema educativo ha sido el detonante de nuevos enfoques pedagógicos que han otorgado un protagonismo especial a la necesidad de enseñar a aprender. Desde esta perspectiva de cambio, y ante la importancia de dar a conocer estrategias que permitan al colectivo de docentes en formación afrontar con éxito desafíos profesionales futuros, el presente artículo recoge los resultados de un estudio de caso focalizado en el análisis de las posibilidades que ofrece el Aprendizaje Basado en Proyectos (ABP) para el tratamiento de las dimensiones de la Competencia para Aprender a Aprender (CPAA) en el área de Educación Artística. En la investigación han participado estudiantes del Grado en Maestro en Educación Infantil, pues son los responsables de visibilizar las posibilidades de las artes y la formación cultural ante el reto de enseñar a aprender desde las primeras etapas educativas. Entre las conclusiones obtenidas cabe destacar la necesidad de concienciar a los y las docentes en formación sobre las finalidades de una educación artística renovada, así como reflexionar sobre cuanto supone poner en relación nuestra disciplina con planteamientos pedagógicos vinculados al desarrollo de habilidades para iniciarse en el aprendizaje y ser capaz de continuar aprendiendo de manera eficaz y autónoma.

The management of displaced radial neck fractures in children is still a controversial topic. The objective of this study is to examine the outcomes of modified Metaizeau technique in the children with displaced radius neck fractures.

The retrospective study included 15 children with displaced radial neck fracture with an angulation of more than 30° who were managed with the use of leverage technique by mosquito clamps and internal fixation with elastic stable intramedullary nailing (ESIN). Radiological and functional assessments were performed during follow-up. Additionally, the patients were evaluated using Mayo Elbow Per- formance Score (MEPS).

All the children could be managed with clamp-assisted closed reduction. The average duration of follow up was 25.5 ± 6.1 months (15-36 months). An excellent elbow function was achieved in all but one patient. Based on Metaizeau classification, excellent, good, fair, and poor outcomes were achieved in 11, 1, 2, and 1 patients, respectively. The average postoperative MEPS score was 98.7 ± 5.1 (80-100).

Clamp-assisted closed reduction and fixation with ESIN is a good choice in the children with displaced radial neck fractures. This technique is associated with good functional and radiologic outcomes in the medium-term. Further studies are warranted with larger sample sizes.
Transient synovitis of the hip : is systematic radiological screening necessary for the detection of Perthes disease?

Current imaging guidelines in Belgium advise a systematic X-ray screening of the hips after an episode of transient synovitis of the hip, in order to detect Perthes disease. The aim of this study was to analyze whether systematic radiological screening is necessary for all children or whether the X-ray indication could be guided by clinical symptoms. A retrospective single center study including all children with the diagnosis of transient synovitis of the hip between 2013 and 2018 was performed. 242 patients with the diagnosis of one or more transient synovitis episodes were included, 102 of whom underwent a follow up X-ray. Persistence or recurrence of symptoms were recorded for all patients, as well as the results of follow-up hip X-rays. 12 children did not remain symptom-free after the episode of transient synovitis. Of these patients 10 had a normal follow-up X-ray and 3 were diagnosed with Perthes disease. 1 patient of those 3 had a normal X-ray but was diagnosed with Perthes disease on MRI. Of the children which remained symptom-free after the episode of transient synovitis, none were diagnosed with Perthes disease afterwards. A follow-up X-ray to exclude Perthes disease after a diagnosis of transient hip synovitis appears to be necessary only in patients with persistent or recurrent symptomatology.
