Therapy for Dutch Elm Disease
Authors: Lanier Gerald
Published: July 2022

An aggregate of 82 American elms in Syracuse New York and Washington D.C. naturally infected with Dutch elm disease were given therapy by pruning infected limbs, injection of benzimizol fungicides, or combinations of these treatments. Pruning alone was applied only when there was a distance of 3 m or more from the last visible streak to the distal cut. Pruning without injection was successful in each of 10 current year infections, but in none of 3 residual infections. Fungicide injection without pruning succeeded in 76% of current year and 33% of residual infections. Fungicide injection plus pruning was successful therapy for 100% of the current year and 71% of the residual infections. Each of five "incurable" trees showed no further symptoms after fungicide was injected directly into infected wood in a large limb or the bole as well as into the root collars. Relatively massive injection of fungicide in trees with root graft-transmitted DED did not succeed.
A Formula for Assessing the Ecological Value of Trees
Authors: Franks Edwin , Reeves John
Published: July 2022

Formulas have been in general use to establish the dollar value of a tree when used in landscaping, or when used for pulp or timber. But none has been developed that recognizes that trees have a real value to the functioning of an ecosystem, unrelated to their value for landscaping or to the lumber or pulp industries. This paper suggests a way to establish a dollar value for any given tree based on the significance of its effects on soil, nutrient, and water conservation, animal usage, and habitat characteristics. Judgements of ecological effects are converted to simple arithmetic steps to produce a numeric dollar value for the ecological contributions of the tree.
The Network Between Utility Forestry and Municipal Forestry: It Does Exist
Authors: Olienyk Deborah L.
Published: July 2022

The association between utility foresters and municipal foresters has been the subject of controversy. To demonstrate that a network does exist with these two groups, goals and objectives are defined by exploring four areas: purpose, attitude, approach, consequence. Comparisons are made to demonstrate how their programs can be integrated for the long-term benefit of the urban forests shared in common.
Field Observations of Tree Injection
Authors: Orr James , Leonard Stewart , Lentz Joseph
Published: July 2022

This paper examines tree injection from the view point of the contracting arborist. Contract arborists are responsible for applying the art and science of tree injection, as developed by the utility foresters, city arborists and chemical manufacturers to its commercial phase. In making a commercial application of plant growth regulators to trees, specifically those trimmed around electrical wires, the contract arborist has encountered a multitude of unexpected situations. These operational problems continually hinder the practice, development and refinement of this new science or management tool. Problems of tree physiology and program implementation were not solved until the desired material could be placed in the tree accurately and consistently. Today many equipment variations exist, each filling a perceived need in the search for reliable trunk injection equipment.

Authors: Dr. Unnati A. Patel  , Dr. Priya Swaminarayan
Published: July 2022

Attendance is for keeping records of number of students present in schools, colleges or in any organization. It is very important constituent in maintaining discipline among students in acollege and imparting quality education in schools, colleges. Complexity of this process increases even more with increase innumber of students. Biometric student attendance system increases the efficiency of the process of taking student attendance.Automatic wireless identification has been facilitated by IoT technology using electronic passive and active tags with suitable readers. In this paper the concept of a simple and portable approach of IoT is applied to student attendance that records the attendance using RFID and Face Recognition. This system aims to automate the awkward process of manually taking and storing student attendance records. It will increase the reliability of attendance records by preventing proxy attendance. As per the requirement by the teacher, the securely stored attendance records can be reliably retrieved. This concept is capable of eliminating time consumption during manual collection of attendance and an opportunity for the educational administrators to capture face-to-face classroom data for allocation of proper attendance scores and for further managerial decisions.
Andean pre-Hispanic pottery forming 3D analysis: a pilot study from Quebrada de Humahuaca (Argentina) using digital methods
Authors: Scaro Agustina
Published: July 2022

Digitization, three-dimensional (3D) documentation and visualization of archaeological materials are processes in increasing development that are used for the enhancement of heritage. These tools have multiple uses for the analysis and research of archaeological objects, although their use in pottery forming techniques studies is less explored. In this paper, diverse digital methods are explored in the study of pottery forming macro-traces, using the 3D model of an archaeological vessel from South-Central Andes. This case is proposed as a pilot study, aiming to reveal the potential of digital techniques for understanding pottery forming techniques. The particular case analysed corresponds to a globular pot of the Humahuaca Black-on-Red style, recovered at the Pucara de Volcán archaeological site, in Quebrada de Humahuaca (Jujuy, Argentina). Initial studies of macro-traces on the pot suggested the use of paddling as the forming technique. The workflow used to contrast this hypothesis included the generation of a 3D model by close-range photogrammetry; and the analysis of the resulting point-cloud and mesh using Morphological Residue Model (MRM) and Virtual Reflectance Transformation Imaging Visualization (V-RTI), with diverse open-source software packages, such as AliceVision Metashape and CloudCompare. These methods increased the micro-topography visibility of the pot surface. As a result, the presence of sub-circular depressions in the body of the pot -similar to percussion cupules-, horizontal pressure lines in the collar, and micro-pull-outs in the maximal diameter of the pot were described. These macro-traces were interpreted as corresponding to the paddling technique used for the elaboration of the pot body —a technique not previously identified in pre-Hispanic traditional pottery manufacturing in the north of Argentina—, and of coiling for manufacturing the collar. The digital methods explored have great potential in the study of pottery forming techniques, although their scope depends on the accuracy of the 3D model analysed.

Authors: Contreras Rodrigo Fernando , Fernández Sánchez Adrián
Published: July 2022

La Carta Arqueológica de Menorca (Islas Baleares, España) de temática subacuática se compone actualmente de 285 elementos que corresponden a pecios, fondeaderos y hallazgos aislados de diferentes periodos cronológicos. La plataforma del Sistema de Información Geográfica (SIG) que hemos diseñado pretendía definir para los próximos años, las líneas de investigación que se pudieran promover, así como recomendar los vestigios que merecen ser protegidos.  
El Departamento de Cultura del Consell Insular de Menorca tiene, entre sus líneas prioritarias, el conocimiento relacionado con la arqueología subacuática de la isla, con el objetivo principal de preservarlo, protegerlo, investigarlo y difundirlo. Con este propósito, en las últimas décadas, se han promovido proyectos y trabajos encaminados a conocer con mayor precisión el patrimonio arqueológico sumergido, elaborando inventarios y catálogos que se han ido insertando en la Carta Arqueológica de Menorca.
La elaboración del proyecto de SIG ha querido estructurar y poner en orden la información que puede extraerse de la Carta Arqueológica, relacionándose a las temáticas que se han incorporado de los factores que condicionan los aspectos geofísicos y medioambientales asociados a la arqueología marítima de Menorca. Los análisis calculados en el SIG, han permitido definir las excelentes condiciones de algunas zonas marinas, que pudieron utilizarse como fondeaderos desde la antigüedad, y el litoral más probable de la isla, que puede ofrecer nuevos vestigios subacuáticos.

Authors: Costa Rafaela dos Santos , Quadra Gabrielle Rabelo , Souza Helena de Oliveira
Published: July 2022

Interdisciplinarity is still considered a challenge in teaching. From this perspective, Ecotoxicology presents itself as a science capable of permeating several areas, especially in Chemistry. The objective of this study was to demonstrate through a narrative literature review, the integration of Chemistry with Ecotoxicology in school education. This study was based on scientific articles and academic papers conducted in Brazil and published in Portuguese. We identified expository, practical and investigative methodologies that are related to chemistry and other subjects and environmental problems that are part of the student’s daily life. Teachers who use interdisciplinary proposals report success in developing critical thoughts and observations by students on the topics discussed. For this reason, the implementation of projects with interdisciplinary teaching and the application of active methodologies should be encouraged. The approximation between universities and schools can be very useful to achieve this objective so that the best infrastructure of laboratories and the knowledge acquired at the university can help in the formation of critical citizens and arouse interest and curiosity for science.

Published: July 2022

The increasing air pollutant emission, mainly in big cities, attracts significant attention to environmental sciences. Brazil boasts an important tropical forest, the Atlantic Rainforest, and the most important remnants areas are located in the state of Rio de Janeiro. In that regard, this study aimed toÂ assess the impact of particulate matter (PM) emitted by traffic in ecosystems belonging to environmental protection areas (EPAs) near important highways with heavy traffic in southeastern Rio de Janeiro, Brazil.Â To the best of our knowledge, this is the most comprehensive study on air pollution and its impacts on EPAs in Brazil. PM concentrationsÂ (TSP, PM10, and PM2.5)Â from 14 air quality monitoring stations and meteorological parameters were obtained between 2014 and 2016 near EPAs. It was verified that CONAMA annual standard (Brazilian legislation) was overtake in five monitoring stations and in eight of them CONAMA daily standard was exceed. Wind direction was mainly from urban centers to EPAs, indicating that urban pollutants reach forest remnants in most cases, which may represent ecological risk. In order to guarantee environmental preservation, new studies should be performed to evaluate deeply the effect of air pollutants on fauna and flora of preserved areas.

Students' expectations and perceptions of the sport offering at the Durban University of Technology
Authors:   , Pillay Magalingam Atheeshey
Published: July 2022

The aim of this study was to investigate customer service quality at DUT. The objectives were: to identify students’ expectations of service quality in sport at the DUT; to determine students’ perceptions of the service quality in sport at DUT; to determine the gap between expectations and perceptions; and to analyse the relationship between selected biographical characteristics and expectations and perceptions of students, using a questionnaire developed from the SERVQUAL instrument. A total of 400 students have completed the survey during the period May 2010 to June 2010. Data were analysed using descriptive and inferential statistical techniques. Several service quality dimensions were identified and as expected, students’ experiences of service delivery fell short of their expectations particularly for the dimension. All the service quality dimensions in the students’ surveys of sport at the DUT contain negative mean gap scores. From these findings the Sports department at the DUT can identify more specifically the failures in its service quality and seek to improve upon them. Service quality dimensions that are deemed to be good predictors of service quality for students of the DUT sport offering have been related to factors such as the “Tangibility”, Reliability”, “Responsiveness”, “Assurance” and “Empathy. It can be observed that all these dimensions have highly negative mean gap scores. Consequently, the Durban University of Technology will have to address these dimensions more precisely in its attempt to improve its service quality, especially the “Reliability” Dimension, which has emerged as the most important service quality predictor.

Particle number concentrations and size distributions in the stratosphere: Implications of nucleation mechanisms and particle microphysics
Authors: Yu Fangqun , Luo Gan , Nair Arshad Arjunan , Eastham Sebastian , Williamson Christina J. , Kupc Agnieszka , Brock Charles A.
Published: July 2022

Abstract. While formation and growth of particles in the troposphere have been extensively studied in the past two decades, very limited efforts have been devoted to understanding these in the stratosphere. Here we use both Cosmics Leaving OUtdoor Droplets (CLOUD) laboratory measurements taken under very low temperatures (205–223 K) and Atmospheric Tomography Mission (ATom) in-situ observations of particle number size distributions (PNSD) down to 3 nm to constrain nucleation mechanisms and to evaluate model simulated particle size distributions in the lowermost stratosphere (LMS). We show that the binary homogenous nucleation (BHN) scheme used in most of the existing stratospheric aerosol injection (a proposed method of solar radiation modification) modeling studies overpredict the nucleation rates by 3–4 orders of magnitude (when compared to CLOUD data) and particle number concentrations in the background LMS by a factor ~2–4 (when compared to ATom data). Based on a recently developed kinetic nucleation model, which gives rates of both ion-mediated nucleation (IMN) and BHN at low temperatures in good agreement with CLOUD measurements, both BHN and IMN occur in the stratosphere. However, IMN rates are generally more than one order of magnitude higher than BHN rates and thus dominate nucleation in the background stratosphere. In the Southern Hemisphere (SH) LMS with minimum influence of anthropogenic emissions, our analysis shows that ATom measured PNSDs generally have four apparent modes. The model captures reasonably well the two modes (Aitken mode and the first accumulation mode) with the highest number concentrations and the size-dependent standard deviations. However, the model misses an apparent second accumulation mode peaking around 300–400 nm, which is in the size range important for aerosol direct radiative forcing. The bi-mode structure of accumulation mode particles has also been observed in the stratosphere well above tropopause and in the volcano-perturbed stratosphere. We suggest that this bi-mode structure may be caused by the effect of charges on coagulation and growth, which is not yet considered in any existing models and may be important in the stratosphere due to high ionization rates and long lifetime of aerosols. Considering the importance of accurate PNSDs for projecting realistic radiation forcing response to stratospheric aerosol injection (SAI), it is essential to understand and incorporate such potentially important processes in SAI model simulations.
Ultradian rhythms in shell composition of photosymbiotic and non-photosymbiotic mollusks

Published: July 2022

Abstract. The chemical composition of mollusk shells is a useful tool in (paleo)climatology since it captures inter- and intra-annual variability in environmental conditions. Trace element and stable isotope analyses with improved sampling resolution now enable the use of mollusk shells for paleoenvironmental reconstructions at a daily to sub-daily resolution. Here, we discuss hourly resolved Mg/Ca, Mn/Ca, Sr/Ca and Ba/Ca profiles measured by laser ablation ICP-MS through shells of photosymbiotic giant clams (Tridacna maxima, Tridacna squamosa and Tridacna squamosina) and the non-photosymbiotic scallop Pecten maximus. Precise sclerochronological age models and spectral analysis allowed us to extract daily and tidal rhythms in the trace element composition of these shells. We find significant expression of these periodicities but conclude that this cyclicity explains less than 10 % of the sub-annual variance in trace element profiles. Tidal and diurnal rhythms explain variability of at most 0.2 mmol/mol (~10 % of mean value) in Mg/Ca and Sr/Ca, while Mn/Ca and Ba/Ca cyclicity has a median amplitude of less than 2 µmol/mol (~40 % and 80 % of the mean of Mn/Ca and Ba/Ca, respectively). Daily periodicity in Sr/Ca and Ba/Ca is stronger in Tridacna than in Pecten, with Pecten showing stronger tidal periodicity. One T. squamosa specimen which grew under a sunshade exhibits some of the strongest diurnal cyclicity. Daily cycles in trace element composition of giant clams are therefore unlikely to be driven by variations in direct insolation itself but reflect an inherent biological rhythmic process affecting element incorporation. Finally, the large amount of trace element variability unexplained by periodic variability highlights the dominance of aperiodic processes in mollusk physiology and/or environmental conditions on shell composition at the sub-daily scale. Future studies should aim to investigate whether part of this aperiodic variability in shell chemistry reliably records weather patterns or circulation changes in the paleoenvironment.
The relationship between fear of COVID-19 and psychiatric symptoms of schizophrenic patients during the COVID-19 pandemic
Authors: DÜNDAR Emrullah , ÇORUM Emine Nur
Published: July 2022

Purpose: Our study aimed to examine the relationship between fear of COVID-19 and psychiatric symptoms in patients with schizophrenia Material and Methods: Following the rules on infection, a face-to-face questionnaire was conducted with 103 patients with schizophrenia. Participants were evaluated by using the COVID-19 Fear Scale (FCoV-19S) and the Positive and Negative Syndrome Scale (PANSS). Results: Participants' average FCoV-19S scores were less than half of the maximum score on the scale. We found that positive symptoms score was significantly negatively associated with FCoV-19S scores, whereas negative symptoms score was positively associated with the FCoV-19S scores in the bivariate model. We found that positive symptoms predicted fear of COVID-19 negatively and significantly, while general psychopathology symptoms predicted fear of COVID-19 positively and significantly.. Conclusion: We think it is necessary to develop situation-specific rehabilitation interventions for this group, which has become more vulnerable to the COVID-19 outbreak. We are of the opinion that various methods of intervention should be developed and addressed in future studies about possible consequences of low or high COVID-19 fear.

Purpose: This study was conducted as a descriptive study to "Investigation of Self-Care Agency and Exercise Efficacy of Individuals Diagnosed with COPD during the COVID-19 Pandemic Process." Material and Methods:The study population consisted of individuals diagnosed with COPD in a city in the south of Turkey. The study sample consisted of individuals who voluntarily participated and met the inclusion criteria. No random sampling was used in the study. One hundred seven individuals who agreed to participate and met the study criteria constituted the study sample. The 'Sociodemographic Information Form,' the 'COPD Exercise Self-Regulatory Efficacy Scale (Ex-SRES), and Self-Care Agency Scale' was used for data collection. Number, percentage, mean, and descriptive statistics t-tests were used to analyze the data. Results: In the study results, it was found that there was a positive and significant relationship between self-care power and exercise efficacy in COPD patients. (p < 0.05). A significant difference was found between individuals diagnosed with COVID-19 and those who were not in terms of self-care agency and exercise efficacy. (p < 0.05). It was found that individuals with chronic disease had lower self-care agency and exercise efficacy than those without the disease. It was determined that the self-care agency and exercise efficacy of individuals diagnosed with COPD for more than ten years decreased. Conclusion: It was found that it is essential to monitor the self-care agency and exercise efficacy of COPD patients during COVID-19, and the self-care agency and exercise efficacy of patients decreased during this period.

«Los adoradores de sangre». Los rituales de la cofradía islámica ‘Isawiya en los ojos europeos (1850-1956)
Authors: Mateo Dieste Josep Lluís
Published: July 2022

Durante decenios, los rituales extáticos de la cofradía sufí de los ‘isawa han atraído la atención de viajeros y periodistas europeos a su paso por el Magreb. A través de los textos de estos observadores externos mostraré las paradojas de estas imágenes de los ‘isawa centradas en remarcar el carácter violento e irracional de sus prácticas rituales, al tiempo que despertaban una morbosa curiosidad por encontrar una explicación de aquello que los testimonios presentaban como unas extravagancias patológicas. Con el ascenso del reformismo islámico y los intereses de la política colonial franco-española, los rituales fueron progresivamente domesticados a partir de los años 1930, y convertidos parcialmente en espectáculo, con el objetivo de evitar un descontrol corporal y ritual que desafiaba al nuevo orden colonial.
Los viajes náuticos de hebreos y fenicios: Eco de la magnificación de Salomón, alegoría del monarca ideal
Authors: Ramis Darder Francesc
Published: July 2022

La fuente bíblica menciona en tres ocasiones los viajes náuticos de Salomón, rey de Judá e Israel, e Hiram de Tiro a Ofir en busca de riquezas (1Re 9,26-28; 10,11; 10,22). A lo largo del estudio señalamos que la mención de los viajes constituye el constructo teológico y literario compuesto entre el ocaso del siglo VI a.C. y la primera mitad del V a.C., para magnificar, en contraposición al fracaso náutico de Josafat rey de Judá (1Re 22,49), la figura de Salomón como prototipo del monarca ideal al que rinden servidumbre las naciones paganas, representadas por los fenicios. La tradición bíblica posterior, manifestada por la traducción griega, latina y árabe continuará engrandeciendo la figura del monarca situando, cada vez en un horizonte más lejano, la localización de Ofir.
Catequesis visual: análisis iconográfico de las imágenes de los catecismos escolares en la educación franquista (1939-1975)

La utilización de la imagen en la educación ha recibido poca atención a pesar de la doble función que cumplen las imágenes en los manuales escolares, una vertiente dirigida a la adquisición de conocimiento (función instructora) y otra, a la transmisión de actitudes, valores y normas (función transformadora), que es una fuente valiosa de investigación histórica, educativa y comunicativa. Se estudian, mediante el análisis de contenido, las características de los catecismos, la legislación de la época relacionada con la publicación de manuales escolares, la presencia de las imágenes, los tipos, la función didáctica y la transmisión de modelos sociales e ideología. La investigación señala que las imágenes de los catecismos escolares no son simplemente reflejos de una realidad que facilita el aprendizaje de los contenidos que se imparten en las escuelas sino que, además, se convierten en una herramienta eficaz en la transformación de los valores y el pensamiento ideológico y religioso del contexto social en que se producen.
Deliberation and Discursive Injustice: A Collective Failure.
Authors: Barba Moisés
Published: July 2022

The purpose of this paper is to expand the theoretical field of discursive injustice by identifying a specific kind of discursive injustice, namely, the kind we are subject to when we are unjustly prevented from exchanging reasons with others. Broadly speaking, discursive injustice is the kind of injustice we suffer when we are unjustly harmed as language users, most notably when we are prevented from using language in ways we are entitled to. The dominant approach to discursive injustice has focused on the corruption of the illocutionary force of a speech act due to the hearer’s improper uptake. I claim that there is a genuinely distinct kind of discursive injustice, which I label as deliberative injustice, that cannot be accounted for by the dominant approach to discursive injustice. In my view, what makes deliberative injustice discursively unjust is that it amounts to denying someone a normative position that she is entitled to as a language user, which I understand in terms of being a source of reasons. Moreover, I explore two ways of trying to illuminate deliberative injustice by appealing to the social level of analysis, namely, by resorting to a structural explanation (Ayala, 2018) to explain how it comes about, and by asking what it signifies for the collective life of groups. In this regard, I show that the structural explanation has some explanatory limitations, and that deliberative injustice essentially constitutes a collective failure.

Que la precariedad, y su incidencia sobre la vida en su totalidad, se encuentra ya asentada entre nosotros, lo conocen de sobra los autores de este magnífico ejemplar. El mismo analiza lo que ya se llama vida precaria en un contexto de permanencia, al inundar toda nuestra existencia desde sus evidentes características: inseguridad, desprotección, fragmentación e individualidad. Pretende el libro, y lo consigue, concretar esos rasgos definitorios de la existencia precaria, dimensiones a las que afecta y espacios donde reside ahora esa novedad histórica.
Cambios en los parámetros vocales de los docentes durante el curso escolar

La voz es una herramienta fundamental para el docente. La alteración de sus cualidades básicas es definida como disfonía y resulta ser muy común. Nuestro objetivo es estudiar si la voz de los docentes cambia, como consecuencia del esfuerzo vocal provocado por su profesión, en los trimestres del curso escolar y tras la jornada laboral, midiendo el índice acústico de calidad de voz (AVQI). Además, estudiamos si el cambio tras la jornada laboral difiere en los distintos trimestres del curso. La muestra está compuesta de 93 docentes de los cuales 40 imparten su labor en un centro público y 53 en un centro concertado. Por sexos, el 29% son hombres y el 71% son mujeres. El 41.4% imparte en infantil y/o primaria y el 58.6% en ESO y/o Bachillerato. Para la grabación de voz se utilizó el programa de análisis acústico PRAAT. Se encuentran evidencias de que en el segundo y tercer trimestre el parámetro AVQI empeora en los docentes de forma significativa tras su jornada lectiva y de forma más acusada en los que imparten ESO y Bachillerato. Los docentes de centros públicos registran niveles AVQI significativamente superiores a los de centros concertados. La disfonía es significativamente menor en los docentes que imparten las materias de música, idioma distinto del castellano y/o educación física. No se encuentran cambios significativos de AVQI entre los distintos trimestres.
Diferencias en el comportamiento glótico y supraglótico y en la estructura de los pliegues vocales entre mujeres con odinofonía y asintomáticas
Authors: Fuentes Christopher , Biermann Christopher
Published: July 2022

El estudio de la odinofonía ha sido escasamente abordado por las disciplinas vinculadas a la terapéutica vocal. La comprensión de aspectos esenciales para su terapéutica, como el comportamiento glótico y supraglótico, aún es emergente. El objetivo de este trabajo fue comparar el comportamiento glótico y supraglótico y la estructura de los pliegues vocales entre mujeres con odinofonía yasintomáticas. Se trabajó con 50 mujeres con voces profesionales, cuya edad promedio fue de 25,78 ± 3,50 años. Se formaron dos grupos, G1 (asintomáticas) y G2 (con odinofonía). Se utilizó un videolaringoscopio con luz continua para examinar la conducta supraglótica y la estructura cordal, y un electroglotógrafo para analizar el comportamiento de los pliegues vocales. En el comportamiento supraglótico, el 64 % de las participantes de G2 exhibió mayor compresión supraglótica en comparación a G1. El acortamiento anteroposterior en conjunto a la compresión medial fue la configuración más frecuente en G2, mientras que el acortamiento anteroposterior en solitario, correspondió a la configuración supraglótica más frecuente en G1. En el 60 y 84 % de las participantes de G2 se observó prominencia del proceso vocal y ventrículo espacioso junto a un pliegue vocal adelgazado, respectivamente. En la electroglotografía se evidenció que en G1 el cociente de contacto fue de 0,50 ± 0,34 y en G2, de 0,41 ± 0,31 (p < 0,05). En conclusión, en las mujeres que sufren de odinofonía se observaron signos de atrofia cordal, mientras que en oscilación se evidenciaron compresiones supraglóticas compensatorias y anomalías vinculadas a la aproximación o aducción cordal.
