Aerodynamic and acoustical effects caused by placing two prefabricated duct silencers in series
Authors: Peterman Karl
Published: September 2021

It once was not uncommon to find ductborne noise control designs and recommendations that would attempt to provide high sound attenuation values, especially for problematic lower frequencies, by using a pair of prefabricated duct silencers in series with one another, sometimes immediately
adjacent but typically separated by some distance. Similarly, heating, ventilating, and air-conditioning (HVAC) duct silencers are occasionally required to accommodate fire dampers or access sections that effectively break up the silencer along its length, creating an empty gap between the
noise-attenuating internal elements. Typical published performance characteristics of prefabricated duct silencers do not include effects from the use of additional silencers nearby and little information is available in common duct design and application literature. This paper will present
information from a series of tests of various silencers in different configurations and spacings in an aero-acoustic test facility that will help describe the effects on insertion loss, generated noise, and pressure drop.
Development of Fly Neighborly helicopter model specific operational noise abatement guidance from acoustic flight test data
Authors: Page Juliet , Rapoza Amanda , Jacobs Eric
Published: September 2021

Improved helicopter noise abatement guidance has been developed based on acoustic test data acquired by NASA, FAA and Volpe in support of the Helicopter Association International (HAI)'s Fly Neighborly Program. This higher fidelity material was developed to supplement previous training
programs based on pilot and operator feedback. The manner of presentation allows pilots to readily interpret the directional noise emission of their vehicle at different operating conditions. Flight path, airspeed, approach descent rate, and deceleration rate can be assessed to optimize flight
patterns both during the pre-flight planning stage and in real time during flight operations in response to local conditions and events. The resultant sound directivity would be displayed as colored noise exposure contours overlaid onto a map of the area in the vicinity of the helicopter.
New Fly Neighborly training modules have been developed utilizing directional operational noise plots based on Volpe's Advanced Acoustic Model (AAM) modeling with empirical sound sphere data from dedicated US Government helicopter flight tests. This paper will describe the acoustic analyses
and will present the updated noise guidance for the AS350, AS365, AW139, Bell 205, Bell 206, Bell 407, R-44, R-66 and S-76D helicopters.
US Federal Aviation Administration Neighborhood Environmental Survey: Study Design and Survey Methodology
Authors: Jodts Eric , Opsomer Jean
Published: September 2021

As part of the agency's broader noise research program, the Federal Aviation Administration (FAA) has undertaken a multi-year research effort to quantify the impacts of aircraft noise exposure on communities around commercial service airports in the United States (U.S.). The overall
goal of the study was to produce an updated and nationally representative civil aircraft dose-response curve; providing the relationship between annoyance and aircraft noise exposure around U.S. airport communities. To meet this goal, the FAA sponsored a research team to help design and conduct
a national survey, known as the Neighborhood Environmental Survey (NES). Residents from households around 20 airports were selected for participation in the survey; the detailed sampling process is covered in another paper. Two survey instruments were administered to adult residents within
the NES: a mail questionnaire and a follow-up telephone interview for the mail respondents. The mail survey was administered to samples of individuals in the selected airport communities in six separate "waves" over a 12-month period starting in October 2015. All mail survey respondents
were invited to complete a follow-up telephone interview, which asked detailed questions on several areas including respondents' opinions on noise, exposure to aircraft noise, relationship to the airport, concerns about aircraft operations, views on airport community relations, among others.
Analysis of the survey responses on annoyance levels and the associated DNL was used to estimate dose-response curves for each individual airport and a national dose-response curve. The national dose-response curve created from the mail questionnaire shows considerably more people are highly
annoyed by aircraft noise at a given noise exposure level compared to historical FICON data. This paper provides a detailed discussion of the survey design and methodology. Additional information describing the motivation to conduct the NES and how its findings will help inform ongoing work
to address aircraft noise concerns; and the noise methodology are provided in companion papers.

O artigo analisa a lógica da política repressiva aplicada a oficiais intermediários e subalternos da Marinha do Brasil após o golpe de 1964. O objetivo é demonstrar que a repressão que atingiu esse grupo que pouco participou dos conflitos políticos do período tem relação com a inserção administrativa num círculo comandado por oficiais nacionalistas partícipes do processo de disputa político-ideológica intensificado desde fins dos anos 1940.
11 de setembro como marco simbólico do revisionismo histórico à direita
Authors: Rocha Vasconcelos Francisco Thiago , Fernandes Mariz Silviana
Published: September 2021

Este artigo aborda o 11 de setembro como acontecimento que simboliza uma mudança no pensamento político de direita, a partir dos Estados Unidos, ao catalisar um conjunto de revisionismos negacionistas orientados no sentido de uma “geopolítica civilizacional” e de uma “guerra cultural”. O cerne desta mudança está na articulação entre três elementos principais: a tese do “choque de civilizações”; os significados elitistas presentes no neoliberalismo sobre a natureza da democracia; e as vertentes da “Escola Tradicionalista”, que dialoga com experiências autoritárias passadas e presentes da direita em reação à modernidade e ao liberalismo.
ataques de 11 de setembro
Authors: Pathé Duarte Felipe
Published: September 2021

As dinâmicas da violência política parecem ser um ponto indissociável de formas concretas de poder. Em termos muito genéricos assentam, por exemplo, na crítica platoniana do “tirano”, no maquiavelismo do “príncipe” ou na crítica marxista de dominação. Há, portanto, uma dialéctica da violência política que põe o Estado (ou outra autoridade política) no centro da análise. Este tipo de violência assume assim o papel de uma praxis destrutiva ou construtiva. Ou seja, o perpetrador de violência política age por três razões: pelo poder, para tomá-lo ou para criá-lo. Mas os ataques de 11 de setembro vieram redefinir este quadro de análise. A par da dimensão instrumental, o carácter expressivo da violência política passou a ser cada vez mais considerado. Por isso, o papel da autoridade política como principal eixo analítico deste tipo de violência tornou-se limitado. Vinte anos depois dos atentados da al-Qaeda, a violência política ganhou outro significado. Como tal, por excesso, ou por defeito, há outros modelos que deverão ser tidos em conta e que colocam a tónica da violência política para lá da instrumentalidade.

Densities of the Eurasian Threetoed Woodpecker Picoides tridactylus calculated from sap row surveys are on par with estimates from fixed route bird censusing
Authors: Ferry Björn , Ekenstedt Johan , Green Martin
Published: September 2021

Species-specific tracks animals can be an effective way of mapping species that are hard to find even if they are present. We used observations of sap rows on trees to calculate densities of Eurasian Three-toed Woodpeckers Picoides tridactylus. We surveyed 14 fixed routes in northern Sweden below the montane forest for sap rows during the autumn of 2020. We used our observations of fresh sap rows together with average home range and proportion of active territories per year derived from the literature, to calculate large-scale woodpecker population density. The density based on sap rows was 0.19 pairs per km2. Densities from fixed route bird observations for different parts of Västerbotten County below the montane forests were 0.13–0.14 pairs per km2, in relative agreement with the estimates from sap rows. We also calculated the population density from fixed route observations in the montane forests, and these were almost three times higher. Our density calculations correspond to 7,900 pairs in Västerbotten County. These results indicate that systematic counts of sap rows can quickly provide credible population density estimates of Eurasian Three-toed Woodpeckers.

Al incorporarse a la vida escolar, el niño experimenta una reestructuración psicológica esencial, pero este niño que culmina su 6to. año de vida y comienza en el 1er. grado, mantiene aún, las características psicológicas propias de la edad preescolar, requiriendo un tiempo de adaptación a los nuevos cambios en su vida. Algunos maestros de 1er. grado, en su manejo pedagógico con los niños, pretenden convertirlos bruscamente en escolares, obviando que este momento constituye una necesidad y de hecho, un período de tránsito de preescolar a escolar, que ocurre en las condiciones físico-ambientales de una escuela. Por tanto, una problemática actual es la necesidad de la preparación de los docentes del 1er. grado en la utilización de estrategias que favorezcan la continuidad entre la educación preescolar y la escolar. Se trata entonces de orientar al maestro en la instrumentación de su labor pedagógica a fin de evitar que se produzca un cambio brusco de una etapa a otra.

El Requisito de Lengua Extranjera y la lectoescritura en la universidad
Authors: Cadavid G. Teresa E.
Published: September 2021

A propósito de la lectura y la escritura en la universidad, vale la pena establecer una comparación: entre la apabullante exigencia del “dominio” de una segunda lengua —culturalmente y de manera general, preferiblemente el inglés, sabemos por qué— y las exigencias propias de la competencia en lectura y escritura del español en el ámbito universitario.Hay una experiencia que se constata a diario en la universidad, al enfrentar como docentes las dificultades de comprensión de textos y expresión escrita (lectura y escritura) manifestadas por losalumnos, principalmente en los primeros semestres, y es que si bien muchos de ellos ya hablan esa segunda lengua —entre otras cosas, porque se les inculcó cultural e institucionalmente esa exigencia desde los niveles de enseñanza básica y secundaria—, sus habilidades comunicativas en cuanto a la comprensión lectora y la expresión escrita del español —del cual son hablantes nativos— es bastante deficiente. Es posible que puedan alcanzar una competencia pareja en el habla corriente de ambas lenguas, pero habría que ver cómo leen y cómo escriben textos académicos en inglés, es decir, textos producidos por las distintas disciplinas de la cultura letrada universitaria, no ya los textos informativos tipo examen Michigan, con los cuales se han familiarizado gracias a la obsesiva preparación, conejercicios básicos de comprensión lectora y expresión escrita, incluso desde el bachillerato.

Hierarchical Control Architecture of Co-located Hybrid Power Plants
Authors: Long Qian , Das Kaushik , Sørensen Poul Ejnar
Published: September 2021

The utility-scale co-located hybrid power plants (HPPs) have been receiving attention globally due to enhanced controllability and efficient utilization of electrical infrastructure. While power plant control has been extensively studied for single-technology power plants in the past decades, how to control a co-located HPP that includes sub-plants with multiple technologies is yet to be well defined. To fill the gap, this paper proposes a novel hierarchical control architecture for co-located HPPs. This control architecture contains four control levels: asset control level, plant control level, HPP control level and HPP energy management system (EMS) level. The objective of HPP EMS level is to find optimal strategies for market participation, and the objective of HPP control level is to execute those strategies from the HPP EMS in real time. The interactions across the control hierarchy are firstly discussed in this paper, where attention is closely paid to interactions between HPP EMS level and HPP control level, and between HPP control level and plant control level. Novel strategies for control coordination are presented to ensure all the control levels work together without counteracting against each other. Frequency control and fault ride-through are two examples to demonstrate such control coordination.
Antibacterial agents reducing the risk of resistance development

Published: September 2021

The most important goal of medical microbiology in terms of treating infectious diseases nowadays and in the coming decades will be the development of antibacterial agents that are effective against resistant pathogens and reduce the selection of antimicrobial resistance. In this regard, along with the search for new classic antibiotics, it is necessary to develop alternative strategies. Virulence factors that determine the key stages of the infection process, both acute and chronic, including adhesins, toxins, bacterial quorum sensing, secretory systems, could be potential targets. The strategy for the development of antivirulence drugs is already showing its potential in the treatment of nosocomial, complicated and chronic infections as part of complex therapy and for prevention. The review presents the results of studies of drugs that have already shown efficacy in model infections in animals or have either passed to the stage of clinical trials or have already been registered. The development of effective combination therapy regimens will minimize the risks of acquiring resistance.

Abstract

Background: Schwannoma of the Intermediate Nerve is rare. The most majority of Cerebellopontine angle (CPA) lesions are Vestibular Schwannomas.

Case description: A 50-year-old woman presented with ear pain, facial palsy and hypoacusis. MRI revealed a CPA tumor. A left retrosigmoid approach and microsurgery was performed and the tumor origin was from the intermediate nerve. intraoperative neurophysiologic monitoring (MNIO) was used during the surgery. Conclusion: Schwannomas of the intermediate nerve is indistinguishable from vestibular schwannomas on preoperatory image, however it’s possible to identify tumor origin during microsurgery dissection with aid of MNIO and origin from intermediate nerve is a reality.

Published: September 2021

Background: Although most traumatic epidural hematomas are secondary to arterial injuries, particularly rupture of the middle meningeal artery, around 9.7% of cases are associated with dural venous sinus injury, leading to poorer prognosis and greater complications. We report a case of a patient presenting cranial trauma with bone fracture and laceration of the transverse sinus producing epidural hematoma, and discuss the main aspects of this condition. Case description: A 47-year-old man struck by a motorcycle was admitted to the Emergency Room with a score of 15 on the Glasgow Coma Scale, evolving over 5 hours with reduced level of consciousness. A cranial CT scan was performed disclosing right parieto- occipital hyperdensity, consistent with acute epidural hematoma, and a parieto-occipital fracture line crossing the path of the ipsilateral transverse sinus. Parietal craniotomy was performed to drain the hematoma, revealing a venous sinus injury requiring immediate repair. Conclusions: This case and discussion highlight the many details and technical specificities to be taken into account by neurosurgeons when encountering intracranial hematoma caused by traumatic injury of the dural venous sinus, and which are pivotal in determining the efficacy of the treatment approach and prognosis of the patient.

The article discusses the methods of cluster and discriminant analysis for constructing mathematical models for the diagnosis of gynecological diseases. Gynecological pathologies occupy a significant place in the structure of morbidity in women. Meanwhile, accurate differential diagnosis of pathologies is often impossible, since gynecological diseases are of a probabilistic nature, most of the diagnostic signs are expressed in qualitative indicators that are individual for each patient. The attending physician has to solve a complex task of analyzing clinical, laboratory and instrumental signs to make an accurate diagnosis. Using the apparatus of Petri nets, a model for the differential diagnosis of gynecological diseases was constructed. On the basis of the obtained mathematical models, the structure and information software for the system of diagnostics of gynecological diseases in medical organizations was formed. The introduction of the developed software product into the medical structure will reduce the likelihood of medical error, as well as increase the efficiency and accuracy of diagnosing patients

In this article, we described the equations of motion of a rigid solid by a matrix formulation. The matrices contained in our movement description are homogeneous to the same unit. Inertial characteristics are met in a 4x4 positive definite symmetric matrix called "tensor generalized Poinsot." This matrix consists of 3x3 positive definite symmetric matrix called "inertia tensor Poinsot", the coordinates of the center of mass multiplied by the total body mass and the total mass of the rigid body. The equations of motion are formulated as a gender skew 4x4 matrices. They summarize the "principle of fundamental dynamics". The Poinsot generalized tensor appears linearly in this equality as required by the linear dependence of the equations of motion with the ten characteristics inertia of the rigid solid.
Regarding the possibility for the prosecutor to carry out procedural actions in case the court returns the indictment
Authors: Chernenko Anatolii , Shiyan Anatolii
Published: September 2021

The article examines the possibility of the prosecutor to carry out procedural actions after the court of first instance returns the indictment from the preparatory court hearing, petitions for the application of coercive measures of medical or educational nature, if they do not meet the requirements of the CPC of Ukraine.

Analysis of the grounds for returning these procedural documents for revision shows that they are different in nature. Some of them are of a formal nature (the date and place of drawing up these documents are not specified, the signatures of the investigator and the prosecutor are not placed, etc.). The formal grounds for returning the indictment and other documents mentioned above do not create any difficulties for the prosecutor in correcting them: they eliminate them, after which these documents are again sent to the court of first instance. Simultaneously, the grounds for returning these procedural documents for revision may be with more serious shortcomings (the accusation formulated by the investigator is vague, there are no established circumstances that aggravate or mitigate the punishment, etc.). When the court determines other grounds for their return, the prosecutor's decision on these grounds is more difficult. And the main problem is the possibility of conducting investigative (search) and other procedural actions to correct the shortcomings in these documents.

It is concluded that the Ukrainian criminal procedure legislation does not contain a mechanism for regulating this issue, and the case law and opinions of lawyers are not unanimous and are often contradictory. Due to these and other reasons, this problem continues to exist today, creating discomfort in the activities of both prosecutors and courts of first and second instance.

The arguments presented in the article substantiate the right of the prosecutor, if necessary, to conduct the necessary investigative (search) and other procedural actions to correct the identified deficiencies in these procedural documents.

To fill the current legal gap on this issue, to eliminate differences in its resolution by judicial authorities and prosecutors, it is proposed to make appropriate additions to the provisions of paragraph 3 of Part 3 of Article. 314 of the Criminal Procedure Code of Ukraine.

Audience facial expressions detected by automated face analysis software reflect emotions in music
Authors: Kayser Diana , Egermann Hauke , Barraclough Nick E.
Published: September 2021

An abundance of studies on emotional experiences in response to music have been published over the past decades, however, most have been carried out in controlled laboratory settings and rely on subjective reports. Facial expressions have been occasionally assessed but measured using intrusive methods such as facial electromyography (fEMG). The present study investigated emotional experiences of fifty participants in a live concert. Our aims were to explore whether automated face analysis could detect facial expressions of emotion in a group of people in an ecologically valid listening context, to determine whether emotions expressed by the music predicted specific facial expressions and examine whether facial expressions of emotion could be used to predict subjective ratings of pleasantness and activation. During the concert, participants were filmed and facial expressions were subsequently analyzed with automated face analysis software. Self-report on participants’ subjective experience of pleasantness and activation were collected after the concert for all pieces (two happy, two sad). Our results show that the pieces that expressed sadness resulted in more facial expressions of sadness (compared to happiness), whereas the pieces that expressed happiness resulted in more facial expressions of happiness (compared to sadness). Differences for other facial expression categories (anger, fear, surprise, disgust, and neutral) were not found. Independent of the musical piece or emotion expressed in the music facial expressions of happiness predicted ratings of subjectively felt pleasantness, whilst facial expressions of sadness and disgust predicted low and high ratings of subjectively felt activation, respectively. Together, our results show that non-invasive measurements of audience facial expressions in a naturalistic concert setting are indicative of emotions expressed by the music, and the subjective experiences of the audience members themselves.
The effects of assessment intensity on participant burden, compliance, within-person variance, and within-person relationships in ambulatory assessment

Published: September 2021

Considering the very large number of studies that have applied ambulatory assessment (AA) in the last decade across diverse fields of research, knowledge about the effects that these design choices have on participants’ perceived burden, data quantity (i.e., compliance with the AA protocol), and data quality (e.g., within-person relationships between time-varying variables) is surprisingly restricted. The aim of the current research was to experimentally manipulate aspects of an AA study’s assessment intensity—sampling frequency (Study 1) and questionnaire length (Study 2)—and to investigate their impact on perceived burden, compliance, within-person variability, and within-person relationships between time-varying variables. In Study 1, students (n = 313) received either 3 or 9 questionnaires per day for the first 7 days of the study. In Study 2, students (n = 282) received either a 33- or 82-item questionnaire three times a day for 14 days. Within-person variability and within-person relationships were investigated with respect to momentary pleasant-unpleasant mood and state extraversion. The results of Study 1 showed that a higher sampling frequency increased perceived burden but did not affect the other aspects we investigated. In Study 2, longer questionnaire length did not affect perceived burden or compliance but yielded a smaller degree of within-person variability in momentary mood (but not in state extraversion) and a smaller within-person relationship between state extraversion and mood. Differences between Studies 1 and 2 with respect to the type of manipulation of assessment intensity are discussed.

Cassava is an important staple food around the world, especially in Africa. It is cultivated throughout the Ivorian territory with predominance in the South. Due to the high demand, some producers opt for an early harvest, neglecting the impact of the harvest stage on the sensory parameters of cassava root derivatives. The objective of this work was to determine the stage of harvest allowing obtaining products of good sensory quality. The sensory characteristics of the attiéké were evaluated at different stages of harvest (11th, 12th, 13th and 14th months after planting the cuttings) of the cassava roots of the Yacé variety which were used for its production. The attiéké obtained in the twelfth month of harvest was generally much appreciated because it was less acidic, less fibrous and more homogeneous and had a better smell. Thus, cassava harvested in the twelfth month of cultivation makes it possible to obtain attiéké with the best sensory characteristics. Therefore, this stage of maturity of cassava roots is recommended for attiéké producers.
