Authors: Imani Zeinab , Sodagar Ahmad , Pourhajibagher Maryam , Hosseinpour Nader Armin , Bahador Abbas
Published: February 2023

Aim: The present study aimed to assess the antimicrobial effects of orthodontic primer containing nano-propolis against the cariogenic bacteria in а rat model.

Materials and methods: Transbond XT orthodontic primer containing 0%, 1%, 5%, and 10% nano-propolis was experimentally prepared in-house. The Wistar rats we used in the study were randomly divided into four groups and their oral cavities were colonized with Streptococcus mutans, Streptococcus sanguinis, and Lactobacillus acidophilus. After anesthetizing the rats, one drop (10 µL) of primer containing different concentrations of nano-propolis was applied to the labial surface of the maxillary incisor and light-cured. The orthodontic composite was applied on the primer and light-cured. One drop (10 µL) of primer containing the same concentrations of nano-propolis was again applied on the surface of composite and light-cured. The number of S. mutans, S. sanguinis, and L. acidophilus colonies in the saliva of rats was quantified at 24 h, at days 4 and 7 using plate counting.

Results: Primer containing 1%, 5%, and 10% of nano-propolis significantly reduced the S. mutans colony count at 24 h compared with the control group (p<0.05). At day 4, the mean S. mutans colony counts in the 5% and 10% nano-propolis groups were significantly lower than that in the control group (p<0.05). Primer containing 1%, 5%, and 10% (all (p<0.05) of nano-propolis significantly reduced the L. acidophilus at 24 hours. Also, at day 4 the mean L. acidophilus colony counts in the 5% and 10% nano-propolis groups were significantly lower than that in the control group (p<0.05). At 24 h and 4 days, the mean S. sanguinis colony count in the 1%, 5%, and 10% nano-propolis group was significantly lower than that in the control group (p<0.05). No significant difference was observed in the presence of all concentrations of nano-propolis at day 7 (p>0.05).

Conclusions: Orthodontic primer containing nano-propolis significantly reduced the colony count of cariogenic bacteria in a rat model.
Behavioral effects of Chaenomeles maulei fruit juice in rats with impaired circadian rhythm
Authors: Borisova-Nenova Vesela , Eftimov Miroslav , Valcheva-Kuzmanova Stefka
Published: February 2023

Introduction: Impaired circadian rhythm (ICR) is a commonly used model of mild stress. The fruit juice of Chaenomeles japonica var. maulei (Mast.) Lavall‚e (CMFJ) is rich in polyphenols known for their anti-inflammatory, antioxidant, and neuroprotective properties. 

Aim: The aim of this study was to investigate the effects of CMFJ on the behavior of rats subjected to ICR.

Materials and methods: Male Wistar rats were divided into five groups of 10 animals each: control group (without ICR), the ICR, ICR+CMFJ2.5, ICR+CMFJ5, and ICR+CMFJ10 groups. ICR was induced by exposing rats to 14 days of constant light. Over these days, oral treatment was administered with distilled water (the control and ICR groups) and CMFJ at doses 2.5, 5, and 10 ml/kg for the respective groups. Then we performed the open field test, the social interaction test (SIT), and the forced swim test (FST) to assess rats’ locomotion, anxiety, and the depressive-like behavior, respectively.

Results: The ICR animals increased their horizontal and vertical locomotion when compared to the controls. The ICR rats did not change significantly the social interaction time in the SIT test and immobility time in the FST. The horizontal and vertical activity of the ICR+CMFJ10 rats was reduced in comparison with ICR animals. Compared to ICR rats, the animals treated with CMFJ at doses of 2.5 and 10 ml/kg demonstrated an improved social interaction and decreased immobility time in the FST. 

]Conclusions: CMFJ prevented the development of ICR-induced hyperactivity and showed an anxiolytic-like and antidepressant-like effect, probably due to its high polyphenol content. 
Is it possible to predict postoperative blood loss in surgery for idiopathic scoliosis?

Published: February 2023

Introduction: Postoperative drain loss can exceed intraoperative blood loss and affect the severity of the patient’s condition. 

Aim: The objective of the study was to find significant predictors of postoperative blood loss in surgery for idiopathic scoliosis.

Materials and methods: We analyzed the data of 140 patients with idiopathic scoliosis. One hundred three patients (group 1) un-derwent Smith-Petersen osteotomy as part of the multilevel pedicle screw fixation; 37 patients (group 2) required no spinal osteotomy. Correlation and regression analysis of the data was performed.

Results: There were significant differences between the groups in the number of fixed segments (p<0.001), the volume of intraoperative blood loss (p<0.001), drain loss (p=0.010), and perioperative blood loss (p<0.001). The study showed that spinal osteotomy had no effect on the volume of postoperative blood loss. A univariate regression analysis revealed the following predictors: patient’s body weight −0.3 [−0.4; −0.2] (p<0.001) and intraoperative blood loss expressed as a percentage of circulating blood volume 0.3 [0.2; 0.5] (p<0.001). The predictors established in univariate regression analysis were significant also in the multivariate analysis. 

Conclusions: The study established the most significant predictors determining the volume of postoperative blood loss in surgery for idiopathic scoliosis: body weight and intraoperative blood loss expressed in percentages of circulating blood volume. A model for pre-dicting the volume of postoperative blood loss was created based on the identified parameters. This model will optimize support for the treatment associated with transfusion during the perioperative period.
A new species of Bush frog (Anura, Rhacophoridae, Raorchestes) from southeastern Yunnan, China

Published: February 2023

In this study, based on morphological and molecular data, a new bush frog species is described from Yunnan, China. Eleven samples of Raorchestes malipoensissp. nov. were collected from Malipo County, southeastern Yunnan. This species can be distinguished from other congeners by a combination of 13 morphological characters. Phylogenetic analyses based on the 16S rRNA gene indicate that these individuals form a monophyletic group, and genetic divergence between this clade and its closest relatives is higher than 3.1%, which is comparable to the divergence between recognized Raorchestes species. The discovery of this new species suggests that additional extensive surveys in the southeastern Yunnan would yield more amphibian lineages yet unknown to science.

Dans cet entretien, Gabriel Hatti, fils de commerçants libanais installés à Boghé à la fin des années 1920, relate sa jeunesse sur les bords du fleuve Sénégal, puis sa formation et son parcours original au sein de la jeune administration publique mauritanienne, d’abord dans les dernières années du régime de Moktar Ould Daddah, puis sous les militaires arrivés au pouvoir à la faveur du Coup d’État de juillet 1978, en pleine Guerre du Sahara. Il évoque également le rôle qu’il a joué à la création, en 1976, puis à la direction (1994-1999) du Parc national du Banc d’Arguin, ainsi que les enjeux multiples auxquels cette aire protégée fut et demeure confrontée.
Une scène n’est qu’un outil marketing
Authors: Berg Heather , Destrument Auriane , Vörös Florian , Damian-Gaillard Béatrice
Published: February 2023

S’appuyant sur une enquête ethnographique par observation et entretien, cet article explore le rôle des sources de revenus complémentaires dans l’économie politique de l’industrie pornographique nord-américaine. Pour de nombreuses actrices de porno, tourner une scène dans un film relève davantage d’une tactique de marketing – visant à valoriser d’autres services plus rémunérateurs – que d’une activité professionnelle principale. Cette tactique permet aux actrices d’exercer un contrôle sur leur vie professionnelle, en tournant à leur avantage un contexte économique qui pourrait sinon les conduire à l’épuisement. Ces sources de revenus complémentaires contribuent cependant à maintenir des salaires peu élevés et à entretenir une armée de réserve de travailleuses enclines à tourner des scènes, y compris pour une faible rémunération et dans de mauvaises conditions. Ces revenus complémentaires placent enfin les travailleuses dans une position ambivalente, où elles se retrouvent à la fois indépendantes, entrepreneuses, managers et productrices. À l’appui d’une analyse féministe marxiste, l’article interroge ainsi la reconfiguration des rapports de classe dans l’industrie pornographique.
Asexualité et partage en ligne d’une expérience minoritaire
Authors: Guay Natacha , Chaulet Johann
Published: February 2023

Notre article entend examiner les usages du site communautaire à destination des personnes asexuelles. L’examen détaillé des interfaces permet de saisir comment cohabitent au sein d’un même espace des outils aux caractéristiques relationnelles différentes. Nous constaterons ensuite que ces outils correspondent à des velléités différentes des utilisateurs qui aspirent pour certains à initier des relations purement amicales quand d’autres entendent mettre en place des relations amoureuses passant par des moments de rencontres physiques. Analysant les occasions de rencontres en face-à-face de certains utilisateurs, nous questionnerons l’émergence d’une norme relationnelle tacite. Ce qu’il s’agira en définitive de montrer, c’est la façon dont l’incertitude et l’indétermination relatives des interfaces et des usages répondent aux incertitudes entourant l’asexualité elle-même tant d’un point de vue identitaire que d’un point de vue social et relationnel. Les usages des sites pour asexuels constituant alors une étape d’un parcours souvent complexe de recherche sur soi.
La haine dans un crime d’infanticide
Authors: Chan Jenny , Chan Jenny
Published: February 2023

Le travail psychothérapeutique avec un patient ayant commis un crime d’infanticide permet d’interroger des processus psychiques dans la transformation de l’amour en haine. En référence à Freud dans ses recherches, la culpabilité de l’acte du crime se trouve dans le fantasme de l’accomplissement d’un désir inconscient au regard de l’interdit. Le narcissisme occupe une place centrale lors des intrications/désintrications pulsionnelles. Dans la contention physique, le corps en scène constitue cet objet intermédiaire entre l’amour et la haine. Toutefois, dans l’infanticide, le moi atteindra l’objet dans la mesure où le meurtre de l’enfant conduira au meurtre de la mère. Quel est le devenir du destin des pulsions après l’acte ? Le psychanalyste est-il disponible pour maintenir un cadre symbolisant et une écoute flottante dans la clinique de l’extrême ? Comment entendre, dans un acte meurtrier, la culpabilité inconsciente du sujet qui réclame son innocence d’enfant meurtri ?
Beckett : une œuvre habitée par les effets de l’hainamoration
Authors: Oppenheim Daniel , Oppenheim Daniel
Published: February 2023

Beckett a subi l’hainamoration maternelle, et toute son œuvre est habitée par ses effets et les tentatives de s’en déprendre. Ce long discours, adressé à sa mère et à Bion, écrit sous l’exigence de sa voix intérieure, décrit au plus près les ténèbres terrifiantes qui l’habitent. Cette œuvre cohérente et courageuse nous apprend beaucoup sur les effets de l’hainamoration maternelle, et nous aide à mieux comprendre et aider nos patients. Cet article ne vise pas à analyser Beckett, mais à lire-écouter son discours, sans prendre appui sur les éléments biographiques, hormis l’hainamoration, en y circulant en tous sens pour y repérer les éléments significatifs et insistants – l’exclusion, le doute, le corps désorganisé, le temps figé, l’aliénation, la mort d’origine, la mère, la femme, la paternité, les mots, la carapace, l’enfermement, etc. – et leur éventuelle évolution. Le discours inconscient en effet ne suit pas une chronologie linéaire.
Cinéma, thérapie, psychanalyse : monter, démonter – de l’ invention de la vérité
Authors: Bécue-Renard Laurent , Bécue-Renard Laurent
Published: February 2023

Un cinéaste parle depuis la singularité de sa pratique artistique. Son œuvre en cours, Une généalogie de la colère, consacrée à l’héritage psychique de la guerre, met en scène thérapie et cinéma dans l’invention de récits signifiants qui permettent aux protagonistes de survivre à la violence vécue.En faisant le pari que le temps de l’écoute documentaire au fondement de la saisie des récits traumatiques soit sans cesse remis en jeu par les protagonistes dans un « après-coup » amené par la thérapie, mais aussi par le cinéaste, l’auteur déplie ici une recherche concrète où l’art de l’écoute et du montage cinématographiques viennent se frotter à l’écoute et au montage analytique. Cinéaste et analysant, l’auteur propose de questionner le rapport du récit signifiant à la vérité. Vérité émancipatrice qui serait ainsi issue non seulement d’une part dite documentaire, mais aussi d’une part de fiction si l’art du « dé » et du « re » montage est accompli par tous – patients, thérapeutes et cinéaste.
Psychanalyse et sciences du vivant : quel dialogue ?
Authors: Delourmel Christian
Published: February 2023

L’auteur propose d’aborder les rapports entre le psychisme et le soma à la lumière des rapports de continuité/discontinuité entre d’une part, le jeu et les aléas des régulations positive et négative des systèmes épigénétique et immunologique et de leurs effets sur les fonctionnements de ces systèmes, et d’autre part, le jeu et les aléas des mouvements psychiques inconscients et conscients de désintrication/ré-intrication des pulsions de vie et des pulsions de destruction, et de leurs effets sur le fonctionnement mental. Il mène son argumentation en mettant en travail deux concepts scientifiques : la notion de principe de désorganisation/réorganisation, qui concernerait tous les ordres du vivant incluant le psychisme dans ses versants inconscient et conscient, et la notion, d’émergence. L’hypothèse est que ce principe se manifesterait, selon des processus spécifiques à chacun de ces ordres, les rapports mutuels entre ces processus de différents ordres hétérogènes étant articulés par des processus d’émergence ascendante et descendante et de récursion organisationnelle.
Réfutations en psychanalyse
Authors: Diatkine Gilbert
Published: February 2023

Selon l’épistémologue Karl Popper, la psychanalyse n’est pas une science, car ses propositions sont constamment confirmées et ne peuvent jamais être réfutées. Et en effet, il n’existe pas d’expérience cruciale susceptible de réfuter la psychanalyse, pas plus qu’aucune autre science humaine. Mais la théorie psychanalytique progresse par réfutations successives. Les moyens qu’utilisent les psychanalystes pour réfuter leurs théories ne doivent pas être confondus avec le respect des postulats de base (Schibboleth) de la psychanalyse. Freud a soutenu un temps un « communisme intellectuel », et toujours montré une ouverture extraordinaire aux idées nouvelles de ses élèves, jusqu’à ce qu’elles soient contredites par les faits. Les réfutations en psychanalyse sont toujours partielles, et conservent en la dépassant la théorie réfutée.
Discussion avec Jean-Marc Lévy-Leblond à propos de l’interdisciplinarité
Authors: Delourmel Christian
Published: February 2023

Un certain nombre de malades somatiques, chez qui la survenue de leurs maladies et de leurs modalités évolutives – parfois surprenantes dans les deux sens – et pour lesquelles la vie relationnelle et psycho-affective de ces patients semblent impliquée dans le déterminisme, justifient une approche interdisciplinaire tant sur le plan théorique que clinique. Mais l’interdisciplinarité soulève de nombreuses questions épistémologiques. L’auteur centre son propos sur l’une de ces questions qui concerne les problèmes soulevés par la translation de concepts d’une discipline à une autre.

La peur d’être la nuit
Authors: Hamano Koichiro
Published: February 2023

Comment comprendre la nyctophobie ? Les uns pensent, comme John Locke, que la nuit n’a rien qui fasse peur, et cherchent la cause de cette angoisse ailleurs que dans l’obscurité. Les autres, à commencer par Edmund Burke, affirment que l’obscurité est la source par excellence de la peur : pour Emmanuel Levinas comme pour Maurice Merleau-Ponty, qui s’appuient tous deux sur la description de l’« espace noir » par Eugène Minkowski, la nuit noire menace de déposséder le sujet de sa souveraineté pour le submerger dans une unité sans articulation. Mais, une dizaine d’années plus tôt, Roger Caillois se réfère aussi à Minkowski pour voir dans la nyctophobie l’effet de la « tentation de l’espace » : pour lui, la peur de la nuit est la peur d’être la nuit – de ne faire qu’un avec elle.
De-Escalation Training for Managing Patient Aggression in High-Incidence Care Areas
Authors: Jones Nelson , Decker Veronica B. , Houston Amanda
Published: February 2023

Health care personnel who have close, face-to-face patient contact experience more workplace violence (WPV) than employees in other fields. Certain health care departments (i.e., high-incidence care areas) have elevated rates of WPV that can have adverse emotional, physical, and financial consequences for patients, employees, and institutions. Health care workers need de-escalation training to efficiently manage patient aggression while also safeguarding patients' dignity and patient–provider trust. The current Plan, Do, Study, Act quality improvement project used insights from an in-depth literature review to create a 1-hour, evidence-based, in-service de-escalation training for personnel from high-incidence care areas. A pre/post design was used to evaluate participants' responses to the Confidence Coping with Patient Aggression Instrument. Post-training, participants reported significantly increased feelings of safety regarding potential patient aggression (
p
= 0.001) and more efficacy regarding their aggression management techniques (
p
= 0.039). Based on the training's results, recommendations were made for future institutional de-escalation initiatives. [

Gut-Brain Axis Perspective on Negative Symptoms and Their Neighbors in Early Adolescence: Can We Move Care Upstream?
Authors: Ford Shannon H. , Bruckner Lorin , Thoyre Suzanne , Baker Maureen J. , Bartlett T. Robin , Hodges Eric A.
Published: February 2023

The current study investigated symptom network patterns in adolescents from a gut-brain-axis (GBA) biopsychosocial perspective. Our secondary analysis of data from the Adolescent Brain Cognitive Development Study assessed symptom relationships using network analysis to provide information about multivariate structural dependencies among 41 signs and symptoms. Cross-sectional EBICglasso symptom networks were evaluated to assess patterns associated with anhedonia and depressed mood. Significant differences were identified between symptom neighbors of anhedonia compared with depressed mood based on stratification by age. The GBA perspective revealed several symptom neighbors that could expand clinical assessment, diagnosing criteria, education, and interventions for adolescents at risk for, or with, anhedonia or depressed mood. Results speak to the unique impact of symptoms on health that are not interchangeable with other symptoms and do not have equal effects. Mental health nurses should consider a holistic and proactive precision health approach to improving health and well-being through evidence-based assessment of symptom associations. [

Virtual reality in human-robot interaction: Challenges and benefits
Authors: Lei Yu , Su Zhi , Cheng Chao
Published: February 2023

Virtual reality (VR) technology has been increasingly employed in human-robot interaction (HRI) research to enhance the immersion and realism of the interaction. However, the integration of VR into HRI also introduces new challenges, such as latency, mismatch between virtual and real environments and potential adverse effects on human users. Despite these challenges, the use of VR in HRI has the potential to provide numerous benefits, including improved communication, increased safety and enhanced training and education. Yet, little research has been done by scholars to review the state of the art of VR applications in human-robot interaction. To bridge the gap, this paper provides an overview of the challenges and benefits of using VR in HRI, as well as current research in the field and future directions for development. It has been found that robots are getting more personalized, interactive and engaging than ever; and with the popularization of virtual reality innovations, we might be able to foresee the wide adoption of VR in controlling robots to fulfill various tasks of hospitals, schools and factories. Still, there are several challenges, such as the need for more advanced VR technologies to provide more realistic and immersive experiences, the development of more human-like robot models to improve social interactions and the need for better methods of evaluating the effectiveness of VR in human-robot interaction.
Discrete Erlang-2 distribution and its application to leukemia and COVID-19
Authors: Mosilhy Mohamed Ahmed
Published: February 2023

Via the survival discretization method, this research revealed a novel discrete one-parameter distribution known as the discrete Erlang-2 distribution (DE2). The new distribution has numerous surprising improvements over many conventional discrete distributions, particularly when analyzing excessively dispersed count data. Moments and moments-generating functions, a few descriptive measures (central tendency and dispersion), monotonicity of the probability mass function, and the hazard rate function are just a few of the statistical aspects of the postulated distribution that have been developed. The single parameter of the DE2 distribution was estimated via the maximum likelihood technique. Real-world datasets, leukemia and COVID-19, were applied to analyze the effectiveness of the recommended distribution.
Stability and Hopf bifurcation in an eco-epidemiological system with the cost of anti-predator behaviors
Authors: Zhang Chunmei , Liu Suli , Huang Jianhua , Wang Weiming
Published: February 2023

The fear effect is a powerful force in prey-predator interaction, eliciting a variety of anti-predator responses which lead to a reduction of prey growth rate. To study the impact of the fear effect on population dynamics of the eco-epidemiological system, we develop a predator-prey interaction model that incorporates infectious disease in predator population as well as the cost of anti-predator behaviors. Detailed mathematical results, including well-posedness of solutions, stability of equilibria and the occurrence of Hopf bifurcation are provided. It turns out that population density diminishes with increasing fear, and the fear effect can either destabilize the stability or induce the occurrence of periodic behavior. The theoretical results here provide a sound foundation for understanding the effect of the anti-predator behaviors on the eco-epidemiological interaction.
La estacionalidad como aprehensión del tiempo: literatura y antropología del tiempo en el Empordà de Josep Pla
Authors: Carbonell Camós Eliseu
Published: February 2023

Muchos pueblos de la tierra basan su aprehensión del tiempo en los indicadores estacionales que van apareciendo y transformándose a lo largo del año, ya sean especies animales o vegetales, cambios en el clima y la luz del paisaje. Algunos escritores han percibido la importancia de estas cuestiones para comprender la cultura de las sociedades sobre las que escribían. En particular, en el período posterior a la segunda Guerra Mundial, en que las sociedades rurales del Mediterráneo se estaban transformando por los efectos de la modernidad, encontramos algunos ejemplos significativos de ello. Este artículo analiza el caso de Josep Pla, uno de los principales autores de las letras catalanas del siglo veinte, cuya obra contiene mucha descripción sobre el paso del tiempo en la sociedad rural catalana, sobre la forma en que es aprehendido el paso del tiempo, y en especial la impresión sensible de las estaciones, en una sociedad agrícola cuyas formas culturales se desvanecen ante él. El articulo enmarca esta obra literaria en el contexto de la etnología del Mediterráneo, antropología del tiempo y en concreto en el estudio de la estacionalidad en la cultura.
El trance. Definiciones y derivaciones tipológicas potenciales (posesión, mediumnidad, chamanismo)
Authors: Horta Gerard
Published: February 2023

Atendiendo a la relevancia del cuerpo como instrumento central de los seres y las sociedades humanas, en este artículo se plantea una aproximación a definiciones clásicas del concepto de trance desde la antropología. Su finalidad reside en discernir aquellos modelos explicativos (Fyrth y De Heusch principalmente) que emplazan este fenómeno social como escenario de tres variantes posibles de realización (posesión, mediumnidad, chamanismo), respecto a aquellos otros modelos (Bourguignon y Duvignaud principalmente) que diferencian explícitamente el trance y la posesión como dos campos distintos. Así, se aportan diversas conceptualizaciones susceptibles de ser interpretadas como contenidos paralelos a pesar de que se mantienen como denominaciones distintas.

External ophthalmomyiasis by larvae of Oestrus ovis (sheep nasal botfly): Second case report from Sri Lanka
Authors: Gunathilake JAMTN , Rajapaksha G , Gunatilake MH , Senanayake SASC , Dayawansa KR , Gunawardena S
Published: February 2023

External ophthalmomyiasis is the invasion of superficial tissues of the eye by fly larvae of the order Diptera. We describe a case of acute conjunctivitis caused by first instar larvae of Oestrus ovis. This is the second such case reported from Sri Lanka. A 28-year-old male was admitted to the National Eye Hospital of Sri Lanka complaining of itching, redness, foreign body sensation and swelling of his right eye. On examination, visual acuity in both eyes was normal; conjunctival injection was noted in the right eye; and the presence of a few motile larvae were observed on the conjunctival surface. The patient recovered completely following the removal of six larvae and treatment with topical antibiotics. The morphological features of the extracted larvae were compatible with the first instar larva of Oestrus ovis. Early detection and removal of botfly larvae will help minimize ocular damage.

Published: February 2023

Introduction: Superficial mycoses (SM) are common in tropical countries.Objective: This study aimed to investigate SM in a group of patients attending the dermatology clinic at the Teaching Hospital, Kurunegala, Sri Lanka.Methods: The study included 125 clinically diagnosed SM patients who visited the dermatology clinic for the first time from December 2014 to March 2015. Demographic data of the participants were recorded using an interviewer administered questionnaire. Suitable samples were examined using the light microscope after 10-20% KOH digestion and were cultured on Sabouraud’s dextrose agar. Fungi were identified on microscopic and macroscopic features.Results: The study population consisted of 47(37.6%) males and 78(62.4%) females with the highest number of patients (27; 21.6%) in the 50-59-year age group. Onychomycosis (47; 37.6%) was the commonest clinical presentation followed by pityriasis versicolor (37; 29.6%), tinea corporis (21;16.8%) and cutaneous candidiasis (8; 6.4%).Direct microscopy was positive in 82 (65.6%) samples. Out of 90 cultured samples, 46 (51.1%) produced significant growth. Malassezia (35) was the commonest identified aetiology followed by dermatophytes (25), Candida (16) and non-dermatophyte molds (10). Among dermatophytes, Trycophyton mentagrophytes 7 (35%) and Trycophyton rubrum 7 (35%) were isolated in higher numbers.Conclusions: SM were common among females in the 50-59-year age group. Onychomycosis and pityriasis versicolor were the commonest clinical presentations. Malassezia species (identified by direct microscopy only) was the commonest aetiology for SM followed by dermatophytes. The leading dermatophytes isolated in this study were T. mentagrophytes and T. rubrum.

Se abordan la apropiación física y simbólica del paisaje a través de la mitología, la religiosidad popular, el senderismo, el montañismo, el ciclismo, las actividades pastoriles y el turismo, completándose el panorama de estudios previamente realizados en el Monte Perdido, el macizo calcáreo más alto de Europa, y el Pico Aneto, máxima altura de los Pirineos. La cristianización de estas montañas se traduce tanto en la mitología y el folclore como en las iglesias, santuarios y abadías dispersos en los valles transpirenaicos. Las conclusiones de la investigación resaltan la importancia de la dimensión simbólica en el paisaje cultural de los Altos Pirineos de Francia, que se construye y recrea entre pinturas rupestres, capillas románicas, caminos jacobeos, leyendas medievales, prácticas pastoriles tradicionales, senderismo, montañismo, termalismo, folclore y multitudinarias carreras de ciclismo.
Ruptura y conexión en la búsqueda espiritual neotradicionalista en Chile
Authors: Berho Castillo Marcelo , García Navarrete Carolina
Published: February 2023

El artículo se enfoca en comprender los modos en que los miembros de una iniciativa congregacional neotradicionalista, llamada Iglesia Nativa Americana del Fuego Sagrado de Itzachilatlan (FSI), llevan adelante un proyecto de vida que definen como un “camino de espiritualidad”. A partir del trabajo de campo antropológico realizado en el centro ceremonial del FSI en Chile, interpretamos las prácticas y narrativas que mujeres y hombres, “buscadores espirituales” de la congregación, despliegan para alcanzar la realización personal. El análisis se concentra en la “búsqueda de visión”, instancia ritual que abordamos a la luz del estudio de los ritos de paso (Van Gennep, 2013) y el simbolismo ritual (Turner, 2013). Los resultados sugieren que en este proceso concurren dos mecanismos que denominamos –inspirados en la nomenclatura de Van Gennep– ruptura y conexión. Ambos mecanismos intervienen de forma más o menos radical en el orden cotidiano, conduciendo a la persona a experimentar y desplegar una transformación de sí misma y del mundo que habita.

This work applied a Compact System consisting of a Reactor Up flow Sludge Blanket (UASB) in conjunction with s Submerged Anaerobic Filter containing polyurethane cubes as support media, followed by a Solar Photolytic Reactor. The compact anaerobic system produced a clarified effluent with low concentration of organic matter, especially dissolved (20 mg .VSS/L), and free of helminthes eggs. These low concentrations of suspended solids facilitated photolytic disinfection process producing a good quality final effluent, of which 90% of the samples were thoroughly disinfected, while the other fraction showed concentration of Thermotolerant Coliform (TTC) at or below 100 CFU/100 mL and high concentrations of nutrients (48 mg . NH4+-N/L and 6,4mg PO4-3-P/L) enabling the use of irrigation for productive purposes. Another advantages of the compact anaerobic treatment consisted of low sludge production, and relatively simple operation without energy consumption. These advantages results in a significant reduction in operational costs of sewage treatment, and, indeed, an outlet for developing countries in tropical climate.

Mathematical modeling of water quality in rivers is an important tool for the planning and management of water resources. Nevertheless, the available models frequently show structural and functional limitations. With the objective of reducing these drawbacks, a new model has been developed to simulate water quality in rivers under unsteady conditions; this model runs on the Vensim PLE® software and can also be operated for steady-state conditions. The following eighteen water quality variables can be simulated: DO, BODc, organic nitrogen (No), ammonia nitrogen (Na), nitrite (Ni), nitrate (Nn), organic and inorganic phosphorus (Fo and Fi, respectively), inorganic solids (Si), phytoplankton (F), zooplankton (Z), bottom algae (A), detritus (D), total coliforms (TC), alkalinity (Al.), total inorganic carbon (TIC), pH, and temperature (T). Methane as well as nitrogen and phosphorus compounds that are present in the aerobic and anaerobic layers of the sediment can also be simulated. Several scenarios were generated for computational simulations produced using the new model by using the QUAL2K program, and, when possible, analytical solutions. The results obtained using the new model strongly supported the results from the QUAL family and analytical solutions.

This paper investigates the behaviour of certain water and sediment quality indicators of a vegetated detention pond system located at Waterlooville, Hampshire, UK. The period of study was 2 years (March 2011-March 2013) with sampling carried out once a month. Statistical analysis was performed using Minitab™. The aim of the study was to examine the changes in quality of various constituents with time and possible linear associations between them. Pond sediments and pond water quality were monitored for a range of variables at each monthly visit. Results indicate that the system demonstrates low levels of pollution while not having a direct impact on the oxygen balance of the receiving water-body. Oxygen demanding substances along with suspended matter and certain metals/elements were found to accumulate in the system with time. Significant linear associations were observed for road salts (containing Na, Cl, Mg) and certain pollutants, suggesting that road salts have a major impact on SuDS water/sediment quality. Sorption characteristics of specific metals were also evaluated by means of adsorption isotherm equations. Three widely used sorption isotherms were employed in this study. It was found that the sorption behaviour of metals is highly variable. This study highlights the dynamic nature of vegetated ponds and the importance of understanding the behaviour of different pollutants for SuDS design.
STUDY ON AMMONIA STRIPPING PROCESS OF LEACHATE FROM THE PACKED TOWERS
Authors: Barros Aldre Jorge Morais , Leite Valderi Duarte , Prasad Shiva , Lopes Wilton Silva , De Sousa José Tavares
Published: February 2023

About 245 thousand tones of municipal solid waste are collected daily in Brazil. Nearly 32 thousand tones of the collected amount are treated in sanitary landfill, which generates biogas and leachate as byproduct. The leachate resulting from sanitary landfill contains high concentration of carbonaceous and nitrogenized material. The crucial question is that the biodegradation of the carbonaceous material is difficult as long as the nitrogenized material is present in the form of ammoniacal nitrogen (NH4+), which compromises performance of biological treatment process. Therefore, a physical and chemical treatment of the leachate should be done before its biological treatment, especially for reduction of ammoniacal nitrogen concentration and for propitiating the realization of application of biological treatment. The treatment of leachate requires specific consideration, which is not needed for other types of waste. In the specific case in this study, where ammoniacal nitrogen concentration was about 2,200 mgN L-1 and the BOD5/COD ratio was 0.3, the study of ammonia stripping process was performed. Ammonia stripping process was studied in packed towers of 35 L capacity each and the parameters investigated were pH, ratio of contact area/leach volume and the aeration time. One of the parameters that influenced most in efficiency of ammonia stripping process was pH of the leachate since it contributes in conversion of ammoniacal nitrogen from NH4+ to NH3.

The rainfall distribution in Bangladesh is not uniform and reflecting topography. Hilly Sylhet region receives substantial rainfall every year compare to other regions of Bangladesh. Though Sylhet region is less vulnerable to drought but weather pattern is not constant and changing day by day. Hence as a part of drought analysis, behavior of dry days is important. This study focuses on dry days pattern and associated changes from daily records of last 54 years for Sylhet region. Monthly, yearly and seasonal variations of dry days were analyzed to check for major changes. In order to investigate extreme dry events, time history of monthly dry days data were transformed into frequency domain using the Fast Fourier Transform (FFT). Variability of dry days in time scale was also checked from filtered signals which is very useful for drought analysis, agricultural development and disaster management for the north-east region of Bangladesh.

The flow in sewers is unsteady and variable between free-surface to full pipe pressurized flow. Sewers are designed on the basis of free surface flow (gravity flow) however they may carry pressurized flow. Preissmann Slot concept is widely used numerical approach in unsteady free surface-pressurized flow as it provides the advantage of using free surface flow as a single type flow. Slot concept uses the Saint-Venant’s equations as a basic equation for one-dimensional unsteady free surface flow. This paper includes two different numerical models using Saint Venant’s equations. The Saint Venant`s equations of continuity and momentum are solved by the Method of Characteristics and presented in forms for direct substitution into FORTRAN programming for numerical analysis in the first model. The MOUSE model carries out computation of unsteady flows which is founded on an implicit, finite difference numerical solution of the basic one dimensional Saint Venant’s equations of free surface flow. The simulation results are compared to analyze the nature and degree of errors for further improvement.
REVIEW ON NATURAL METHODS FOR WASTE WATER TREATMENT
Authors: Sahu Omprakash , Dubey Ashwani Kumar
Published: February 2023

In Ethiopia, the most common method of disposal of waste water is by land spreading. This treatment method has numerous problems, namely high labor requirements and the potential for eutrophication of surface and ground waters. Constructed wetlands are commonly used for treatment of secondary municipal wastewaters and they have been gaining popularity for treatment of agricultural wastewaters in Ethiopia. Intermittent sand filtration may offer an alternative to traditional treatment methods. As well as providing comparable treatment performance, they also have a smaller footprint, due to the substantially higher organic loading rates that may be applied to their surfaces. This paper discusses the performance and design criteria of constructed wetlands for the treatment of domestic and agricultural wastewater, and sand filters for the treatment of domestic wastewater. It also proposes sand filtration as an alternative treatment mechanism for agricultural wastewater and suggests design guidelines.
Developing a Criteria Framework for Evaluation of the Urban Development Plans in Iran: Bridging the Gap between Knowledge and Action
Authors: Maghsoodi Tilaki Mohammad Javad , Hedayati Marzbali Massoomeh
Published: February 2023

This article discusses the conceptual requirements in preparing an evaluation framework for the urban development plans in Iran as well as modifies the evaluation criteria proposed in previous studies. Although applying a highly refined evaluation framework for assessing the quality of urban development plans can increase the efficiency of the development process, employing an unmodified framework in a specific urban context may negatively affect the development process because of exclusive conditions. An evaluation framework based on the worldwide experiences cannot normally be employed in the evaluation of the urban development plans of Iran. Hence, this research contributes to the advancement of a more adaptable evaluation framework for evaluation in four parts. These parts include (i) the examination of the urban development process of Iran; (ii) the extraction of a general evaluation framework from different studies and worldwide experiences; (iii) the analysis of the effective elements for the urban development plans of Iran through SWOT analysis; and (iv) the generation of an evaluation framework based on a preliminary analysis of the specific situation of the urban development plans of Iran.
