В работе исследованы показатели внешнего дыхания у студенток и студентов с помощью спирографа «Диамант-С» с использованием методики «МВЛ». Спирографические показатели у испытуемых регистрировали в состоянии покоя и после двигательных проб – степ-тести проба Мартине. Полученные данные говорят о том, что двигательная нагрузка вызывает увеличение параметров внешнего дыхания, усиление и улучшение вентиляционной функции легких. В то же время результаты нашего исследования показывают, что выполнение методики «МВЛ» вызывают трудности у испытуемых.
Улиц женского пола исследуемые параметры оказались неудовлетворительными. Результаты исследования говорят о плохой адаптированности функции дыхания испытуемых к физической нагрузке, сниженных функциональных резервах дыхательной системы, в частности у лиц женского пола. Использование методики «МВЛ» для изучения состояния функции внешнего дыхания у студентов может оказаться информативным методом.

Die Sache mit dem Wirkungsgrad
Authors: Sigloch Uwe
Published: October 2021

Der energetische Wirkungsgrad beschreibt per Definition das Verhältnis von nutzbarer zu aufgewandter Energie. Das gilt natürlich auch für Ventilatoren. Allerdings ist es nicht so einfach zu entscheiden, welcher Ventilator wirklich den besten Wirkungsgrad hat und mit größtmöglicher Energieeffizienz arbeitet – denn Ventilatoren sind komplexe Strömungsmaschinen, die auf jede Veränderung reagieren. Das können zum Beispiel die Einbausituation, Drehzahlvariationen oder veränderte Druckverhältnisse durch Filterverschmutzung sein. Einen Ventilator, der immer und überall mit dem „besten Wirkungsgrad“ arbeitet, gibt es folglich nicht. Für die meisten Anwendungen in RLT-Geräten sind allerdings Radialventilatoren die bessere Wahl.

Stratified Ranked Set Sampling With Missing Observations for Estimating the Difference
Authors: Bouza-Herrera Carlos N.
Published: October 2021

The authors develop the estimation of the difference of means of a pair of variables X and Y when we deal with missing observations. A seminal paper in this line is due to Bouza and Prabhu-Ajgaonkar when the sample and the subsamples are selected using simple random sampling. In this this chapter, the authors consider the use of ranked set-sampling for estimating the difference when we deal with a stratified population. The sample error is deduced. Numerical comparisons with the classic stratified model are developed using simulated and real data.

One of the main objectives of the university is research contribution to other two-year colleges in the region, such as the College of the Marshall Islands and the College of Micronesia, Yap State Campus. The importance of indigenous knowledge, the art of researching, cultural preservation, indigenous research methods, educational responsibilities, and imposter syndrome among UOG undergraduate students are discussed throughout the chapter, noting that education should be seen as an agent of social change by promoting indigenous scholarship, indigenous research methods, indigenous languages, sense of identity, and putting forth significant contributions to the academic literature of Micronesia.
Misconceptions and Mistranslations
Authors: Rutun Elizabeth Midil
Published: October 2021

For years the Yapese language has been perceived to be on its way out. In this chapter, this perceived looming death of language is examined as a necessary tangent to traditional Yapese practices, specifically traditional Yapese dances. It examines how the preservation of the traditional practice of dancing is important to the survival of the language and how meaning is created. In this chapter, meaning is specifically gleaned from the body and the spaces from which the traditional Yapese dances emerge. Furthermore, this chapter illustrates how instances of failure to appropriately use meaning in association with dance has resulted in lost meaning.
The Impact of School Social Bonds
Authors: Cabrera Debra T.
Published: October 2021

Students' experiences in the school environment are not limited to purely academic activities, responsibilities, and relationships. Their complete educational experience encompasses social ties, commitment centered on stakes in conformity, beliefs about rules and regulations, and involvement in pursuits that are indirectly tied to their scholastic performance. Using CNMI Youth Survey data, this chapter explores these social bonds in the school setting and examines their impact on indigenous and indigenous high school students in the Northern Mariana Islands. The relative importance of these social bonds is compared to the influence of social bonds outside the school environment. The findings highlight the importance of teacher attachment and the belief in the validity and fairness of school rules on the risk-behavior for both indigenous and non-indigenous youth, with non-indigenous youths experiencing teacher attachment as a relatively stronger protective factor.
Nanomaterials and Pollution Control
Authors: Almansoori Latefa , Nazir Asiya
Published: October 2021

With nanoscience, new environmental benefits have emerged to aid pollution control. Nanotechnology is becoming beneficial for air and water pollution control and eradication in the future. Air pollution can be controlled with nano-adsorptive materials, nanocatalysis, and nano filters. For water pollution, nanofiltration and nano sorbents techniques are used. Nanotechnology establishes a framework to manipulate the molecular structure of objects depending on the characteristic to generate new materials. Environmental pollution is being controlled more efficiently and strategically through the application of nanotechnology. The technology deals with numerous contaminants like nitrogen oxides, volatile organic compounds, carbon dioxide, among other harmful gases. The research narrows down to the argument that nanotechnology has a positive impact on environmental protection and provides an effective way to eliminate pollution by developing reliable treatment plans. In this chapter, the authors have briefly discussed the different nontechniques applied to control the pollution.

Web-based learning is an emerging and innovative approach to teaching and learning that meets the evolving needs of adolescent learning. Adolescents should embrace the transformation from traditional brick-and-mortar classroom practices to a web-based environment. Stakeholders must continuously overcome the challenges of web-based learning. Future research can concentrate on developing well-defined web-based course content that supports the holistic learning needs of adolescents and the development of a web-based learning model for adolescents.
Human Rights Literacy (HRL) to Promote and Sustain Attitudes and Behaviours Supportive of Social Justice
Authors: Jayasundara Chaminda Chiran
Published: October 2021

This chapter explores what Human Rights Literacy (HRL) involves and how it establishes and develops improved rights of the citizens supportive to social justice in the society. People with different cultural backgrounds have the fundamental right to be literate members of society. However, due to various cultural influences, this right is somewhat restricted to certain individuals. For example, girls' education has become controversial in some lands. There are still instances in some cultures where people of all walks of life, such as LGBTI, Blacks, Indigenous people, migrants, etc., are helpless in the face of their rights. Thus, legal literacy and its unique component of human rights literacy are essential to ensure the protection of human rights. A theoretical framework is eventually drawn up by summarising the findings of the study.
Building Civic Engagement in Smart Cities
Authors: Adetayo Adebowale Jeremy
Published: October 2021

Climate change, poverty, and economic inequality are some of the threats to civilization in today's cities. This has given rise to the development of smart cities as a solution to the threat. However, this smart initiative did not solve the problem. In the face of this predicament, in order for cities to maintain their position, civic engagement must be undertaken by involving citizens in finding a collective solution with the support of smart library. Cities cannot plan or position themselves effectively until they grasp and exploit the existence of the smart library. The chapter explores the practical application of smart libraries to civic engagement. It identifies smart library strategies for building civic engagement in smart cities. The chapter also identifies possible challenges to smart library initiatives in smart cities and makes recommendations.
Smart City Technology and Civic Engagement in Ontario, Canada
Authors: Goodyear Sarah
Published: October 2021

As smart technologies become more integrated with daily life, vital digital literacy skills are necessary for citizens to engage with and benefit from their cities, local government, and economy. Libraries play an important role in mitigating the growing wealth gap in our communities, especially as it relates to opportunities provided by emerging technologies. With the call for smart city proposals in Toronto, Ontario, what role will the city's LAMs have in collaborating with these future developments? The Toronto Public Library (TPL), a trusted public institution, has a stake in implementing various frameworks and collaborating with government agencies in addressing public concerns around technologies that collect personal information for various purposes and ensuring that vulnerable populations are not left behind. Following an examination of the role libraries play in mitigating consequences of the digital divide, this chapter will discuss the various ways in which TPL and similar community libraries have been involved with digital literacy and inclusion. It will also explore how TPL has been identified by government agencies as a vehicle for civic engagement and oversight in the former Sidewalk Toronto smart city plan.
Going Telemental
Authors: Respess Shaun
Published: October 2021

Telemental health (TMH) is considered by many to be the future of mental healthcare, with some claiming that these methods should replace more traditional approaches. Early teletherapeutic initiatives demonstrate an immediate set of benefits for patients including improved access to care, reduced costs, better schedule flexibility, greater environmental familiarity, and higher rates of patient engagement. Notable limitations to TMH include enhanced privacy concerns, the variable digital literacy of certain populations/persons, and technological instability. However, other limitations regarding therapeutic relationships, experiences, and settings have gone undertheorized and are not sufficiently represented in the current research. This chapter surveys these considerations and argues that digital medical interventions are unable to effectively replicate the same degree of ‘contact' and ‘intimacy' available in physical care; providers should therefore be cautious in wholly replacing in-person methods or in implementing a standalone paradigm of digital care.

Authors: Noor Rasha A. Abdel , Eissa Mervat , Okda Hanaa I. , Abdelnabi Hend H. , Ahmed Sahar A. , Mohammed Eman F. , Salam Noha Abdel , Zahran Enas S.
Published: October 2021

Background

Proliferative lupus nephritis (LN) is an aggressive pathological lesion of LN. Corticosteroids, cyclophosphamide (CYC) pulse therapy either by high dose; National Institute of Health (NIH) CYC or low dose; European cyclophosphamide regimen (EURO-CYC), and mycophenolate mofetil (MMF) are the best valid lines for treatment, but the choice between them is still challenging. The objective of this study was to compare the efficacy of both CYC regimens and MMF in the treatment of proliferative LN patients.

Patients and methods

We retrospectively collected the data of 225 biopsy-proven proliferative LN patients (adults and juveniles) from five tertiary centers. Forty four of patients received low-dose regimen, 124 received high-dose regimen, and 57 received MMF. All demographic data, laboratory tests, activity markers, and systemic lupus disease-activity index were recorded and compared at initial presentation and at 3, 6, 12, and 24 months of follow-up.

Results

After 6 months of treatment, 61.2% of NIH-CYC group reached complete response, while the rate was 40.9% of EURO-CYC group and 52.7% for MMF group, and the results were in favor for the NIH group over EURO group, while there was no difference between NIH and MMF groups, but at the end of 12th, 18th, and 24th months of follow-up, the outcomes of the three groups were comparable in efficacy and safety.

Conclusion

For induction treatment of proliferative LN, high-dose CYC shows a better and rapid complete response after the sixth month of treatment in adults and juvenile LN patients, but after the first year of therapy, the three regimens have comparable efficacy and safety.
CMV viraemia in kidney transplantation; Risk factors and outcomes in the era of prophylaxis
Authors: Eltahan Alshymaa R. , Sarhan Iman I. , Hafez Amal S.A.F. , Mahdi Mamdouh M. , Halawa Ahmed
Published: October 2021

Background

Cytomegalovirus (CMV) is among the most prevalent opportunistic pathogens sequencing solid-organ transplantation. Viral immunomodulatory effect can result in the deleterious indirect impacts of CMV over the patient and the graft. The aim of this work was to study the risk factors and the outcomes of CMV viremia in kidney-transplantation recipients.

Patients and methods

Via a retrospective cohort analysis, we tracked 320 kidney-transplantation recipients’ archives who had their kidney grafts from the beginning of January 2008 to the end of December 2013. The data of 307 recipients were recorded. The study groups were tracked for 10 years post kidney transplantation for the cumulative incidence of CMV viremia, possible risk factors, and incidence of significant post-transplant clinical events.

Results

One-hundred twenty-seven recipients were CMV-positive, with the first year's cumulative incidence 36.3% post kidney transplantation. The recipient's age, pretransplant hypertension, and CMV serostatus mismatch were independent CMV viremia risk factors. CMV was not an independent predictor for the decreased patient survival in this study, but was associated with a significantly reduced graft function as assessed by estimated glomerular-filtration rate.

Conclusion

Screening, prophylaxis, and prompt treatment have negated the negative outcomes of CMV viremia on patient and graft survival.
Comparison of cooled and conventional radiofrequency applications for the treatment of osteoarthritic knee pain
Authors: Kocayiğit Havva , Beyaz Serbülent Gökhan
Published: October 2021

Background and Aims:

Osteoarthritis is a progressive degenerative joint disease that affects the joint cartilage and surrounding tissues. It has been determined that osteoarthritis-induced knee pain is the most common cause of physical disability in the elderly.

Material and Methods:

In this study, the genicular nerve RF treatments of patients with osteoarthritic knee pain conducted at the Sakarya University Training and Research Hospital in the algology clinic of the Anaesthesiology and Reanimation Department between January 2016 and December 2016 were retrospectively examined. The preoperative and postoperative 2nd, 6th, and 12th week visual analog scale (VAS) and Turkish validated Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were recorded. In addition, any complications after the treatment and side effects (bleeding, neurological damage, infection, etc.) were recorded in the file.

Results:

When the data of the patients were evaluated statistically, the preoperative VAS and WOMAC scores were found significantly decreased compared with the postoperative 2ndweek, 6thweek, and 12th week scores in patients who applied both conventional radiofrequency (RF) and cooled RF. However, there was no statistically significant difference between the two techniques.

Conclusion:

We found that both cooled and conventional RF techniques in genicular nerve ablation are similarly effective in reducing pain in patients with osteoarthritis-induced knee pain and improving patients’ physical functions. The complication rates are very low and there was no superiority to each other.

Authors: Singhal S. K. , Kaur Kiranpreet , Yadav Pushpa
Published: October 2021

Background and Aims:

To evaluate the role of experience in acquisition of skill of orotracheal intubation in adults.

Material and Methods:

A prospective randomized study was conducted on 307 patients of either sex, belonging to ASA grade I and II (aged 18-60 years) posted for surgery under general anaesthesia. The patients were subjected to DL and ETI procedure, which was performed by five different groups of participants. Group 1 consisted of first-year resident of anaesthesiology with experience of less than 10 intubations, group 2 for second-year resident, group 3 for third-year resident, group 4 for senior resident and group 5 for consultant. Ease of mask ventilation, time taken for intubation, number of attempts, success rate, and ease of intubation were assessed for all the groups.

Results:

Categorical variables were analysed using Chi-square test. For all statistical tests, aPvalue less than 0.05 was taken as a significant difference. Maximum difficulty in mask ventilation was encountered by group 1 anaesthesiologist, that is, in 69.2% of the patients. Group 1 took maximum time to intubate, that is, 47.98 ± 31.54 sec and least time was taken by group 5 anaesthesiologist (9.55 ± 6.93) sec. First attempt success rate was least in group (80.0%). Group 1 had success rate of 96.9%, whereas rest all groups had 100% success.

Conclusion:

Skill of mask ventilation and intubation and time taken for intubation grossly improves with increasing experience. Minimum of 25 intubation attempts should be required by an anaesthesiologist resident in elective scenario to achieve 100% success rate in our study.

Authors: Banerjee Arnab , Saini Savita , Lal Jatin
Published: October 2021

Background and Aims:

The purpose of this study was to prospectively examine the effects of pneumoperitoneum and the reverse Trendelenburg position on cardiac hemodynamics during laparoscopic cholecystectomy using transthoracic echocardiography (TTE).

Material and Methods:

In this prospective observational study, after institutional review board clearance, forty patients of either sex of ASA I-II status undergoing laparoscopic cholecystectomy were enrolled in the study. Changes in cardiac output, stroke volume, and ejection fraction were recorded using TTE at different time intervals: Preoperatively, before creation of pneumoperitoneum, 5 min after creation of pneumoperitoneum, and 5 min after setting the operative reverse Trendelenburg position with legs at the level of the hips. All statistical analyses were performed using the statistical program SPSS version 16 andPvalue less than 0.05 was considered as statistically significant. Data were examined using mixed analysis of variance (ANOVA) followed by post hoc Bonferroni correction.

Results:

There was significant fall in cardiac output (CO) (45%,P< 0.001), stroke volume (SV) (42%,P< 0.001), and ejection fraction (EF) (31.8% change,P< 0.001) after creation of pneumoperitoneum with significant rise in MAP (11%,P< 0.001). But with reverse Trendelenburg position, there was a significant improvement of CO (30%), SV (28%), and EF (21% change) in comparison to values after pneumoperitoneum, but still remained below baseline. There was no change in heart rate at different time intervals. There was no significant difference in hemodynamics between ASA I and II patients.

Conclusion:

Patients undergoing laparoscopic cholecystectomy undergo significant hemodynamic changes after pneumoperitoneum and reverse Trendelenburg position.

Authors: Kumar Niraj , Bindra Ashish , Singh Gyaninder Pal , Goyal Keshav , Chaturvedi Arvind , Yadav Naveen , Yadav Arun Kumar
Published: October 2021

Background and Aims:

Posterior vessel wall puncture (PVWP) is a common complication of ultrasound (US) guided central venous cannulation. We evaluated and compared the frequency of PWVP of internal jugular vein using short axis (SA) and long axis (LA) approach of US-guided needle cannulation. As a secondary objective incidence of carotid puncture was assessed.

Material and Methods:

Prospective, single-blinded, cross over, observational study at Urban Level I Neuroanesthesiology and Critical Care Department. Residents receiving standard education on ultrasound-guided central venous cannulation were asked to place an US-guided catheter using either short axis or long axis approach on a human torso mannequin. During the procedure, the path of the needle was carefully observed by the investigator for any PVWP and carotid puncture without interference with the placement procedure. The confidence level of the resident for the intraluminal placement of the needle tip was measured on a 10-point Likert scale.

Results:

Forty residents participated in the study. The incidence of PVWP in SA and LA group was 40% and 17.5% respectively and was statistically significant (p = 0.026). There was no incidence of carotid artery puncture in either of the group. The mean confidence of intraluminal placement of needle was significantly higher in the LA group (8.32) as compared to the SA group (5.95).

Conclusion:

Lower incidence of PVWP was seen in LA as compared to the SA approach during US-guided IJV cannulation in phantom in residents having previous experience of CVC (central venous cannulation) in landmark technique only. Participants were more confident about intraluminal needle placement in the LA group compared to the SA group.
Factors predicting difficult spinal block: A single centre study
Authors: Prakash Smita , Mullick Parul , Kumar S Suresh , Diwan Sahil , Singh Rajvir
Published: October 2021

Background and Aims:

Several factors determine the success of dural puncture. We aimed to assess the association of first puncture success and number of attempts with characteristics of the patient, provider, technique and equipment.

Material and Methods:

This prospective, observational study was performed in 1647 adult patients undergoing surgery under spinal anesthesia. Patient characteristics, anatomical landmarks, spinal bony deformity, provider experience, technique, skin punctures, needle redirections, subarachnoid space depth, and complications, if any, were noted. Difficult dural puncture was assessed by first puncture success and number of attempts (skin punctures plus needle redirections) required for successful needle placement.

Results:

First puncture success was obtained in 872 (52.9%) patients. Failed dural puncture occurred in 4 (0.2%) of 1647 patients. Multivariate logistic regression analysis revealed that longer distance from C7 vertebral spine to tip of coccyx (P= 0.04), lower subarachnoid space depth (P= 0.001), good quality of bony landmarks (P= 0.001) and absence of crowded spine (P= 0.02) were associated with first puncture success. Male gender, poor or no spinal landmarks, presence of bony deformity and lower level of provider's experience predicted increased number of attempts for successful dural puncture.

Conclusion:

First puncture success of spinal block was influenced only by patient's anatomical factors, whereas the number of attempts required for successful block were predicted by both provider and patient factors.
Human errors and their prevention in healthcare
Authors: Sameera Vattipalli , Bindra Ashish , Rath Girija P.
Published: October 2021

Human errors form a significant portion of preventable mishaps in healthcare. Even the most competent clinicians are not immune to it. Errors in the perioperative period can often have grave consequences, and hence, perioperative clinicians need to be aware of the impact of human errors and how to minimize them. Errors are broadly classified into two kinds: latent and active errors. While active errors need to be addressed at the individual level, latent errors indicate organizational inadequacies. This review describes common errors in perioperative settings, the impact of such errors on healthcare, and preventive strategies to minimize such errors in daily patient care.
Intravenous lidocaine infusion in a case of severe COVID-19 infection
Authors: Rylova Anna , Chowdhury Seema , Amirfarzan Houman , Leissner Kay B. , Schumann Roman
Published: October 2021

A subset of patients with COVID-19 develops a severe inflammatory response that may lead to respiratory and multiorgan failure. Effective treatment strategies to mitigate or interrupt this self-destructive inflammatory process are limited. The local anesthetic lidocaine has anti-inflammatory properties in addition to its analgesic, antiarrhythmic, and sedating effects that may be beneficial in critically ill COVID-19 patients. We report the case of a patient with COVID-19 induced severe respiratory distress who was intubated and received supportive treatment including proning and neuromuscular blockade. He developed a strong inflammatory response that we treated with an intermittent lidocaine infusion resulting in subsequent resolution. This case occurred prior to emerging data from a large dexamethasone use trial that demonstrated a survival benefit from its use in hospitalized COVID-19 patients. At the time, lidocaine was the only anti-inflammatory medication our patient received.
A rare case of duodenal inversum- A laparoscopically manageable entity
Authors: Dasgupta P , Somasundaram S , Balasubramanian S , Palanisamy S
Published: October 2021

Duodenal inversum is a rare disease not frequently encountered in clinical practice. The diagnosis is usually made late due to its rarity. Many other causes of abdominal pain like ulcer disease, pancreatitis, malrotation are mostly thought of initially and the diagnosis is usually missed. Only a few cases of duodenal inversum present with outlet obstruction. Duodenojejunostomy is perhaps the ideal management for duodenal inversum if the patient presents with outlet obstruction. Our intention is to create awareness of such a rare disease with an available definitive treatment option in the form of minimally invasive surgery.

Authors: ŞAHİN Sadettin , PUL Muharrem
Published: October 2021

Bu çalışmada %99,5 ticari saflıktaki alüminyum malzeme içine vortex yöntemiyle %2, %4 ve %8 oranında FeB (ferrobor) takviye edilerek kompozit numuneler üretilmiştir. Daha sonra üretilen kompozit numunelere, mikroyapının sıkıştırılması amacıyla sıcak presleme işlemi uygulanmıştır. Mikroyapı analizleri için SEM görüntüleri çekilmiş ve bazı mekanik özellikleri belirlemek üzere sertlik ölçümleri, çekme testleri ve abrasif aşınma deneyleri gerçekleştirilmiştir. SEM görüntülerinden FeB takviye miktarının artmasıyla kompozit yapıdaki topaklanma gözenek miktarının arttığı anlaşılmıştır. Kompozit yapı içindeki FeB oranını artmasıyla sertlik, çekme dayanımı ve abrasif aşınma dayanımı değerleri önce artmış daha sonra azalmıştır. Her üç mekanik deneyde de kompozit yapı benzer davranış sergilemiştir. Bu tür kompozit yapılarda FeB takviye oranın belli bir orana kadar mekanik dayanımı arttırdığı ancak daha yüksek oranlara çıkıldığında ise mekanik dayanımı azaltıcı etki yaptığı sonucuna varılmıştır.

Os fundamentos históricos do protestantismo brasileiro – uma introdução
Authors: Santana Wilson
Published: October 2021

Este artigo apresenta uma introdução à história do protestantismo no Brasil, abordando as diversas fases da presença dessa vertente do cristianismo aqui desde o período colonial.   O texto discute as ações protestantes franceses no século XVI no Rio de Janeiro, dos holandeses na região que hoje é o nordeste brasileiro, dos imigrantes de origem europeia durante o século XIX e, finalmente o chamado protestantismo de missões, instalado no país a partir da secunda metade do século XIX e que se consolidaria ao longo do século XX. Destaca, por meio da literatura produzida e ou distribuída por esses protestantes nos referidos contextos e, herdeira do movimento reformador do século XVI, tinha como ideal, devido às suas convicções religiosas, submissas ao ensino bíblico, a promoção das liberdade individual e da responsabilidade pelas implicações mais amplas da ética reformada para o desenvolvimento social, tendo a educação como um dos principais meios para que os seus objetivos fossem alcançados.

Análisis de falla de encendido en motores de combustión utilizando señales de
vibración basado en el cálculo y reducción de indicadores estadísticos
Authors: García-Basurto Alejandro , Saucedo-Dorantes Juan José , Pérez-Cruz Ángel , Osornio-Río Roque Alfredo
Published: October 2021

En este trabajo de investigación se propone una metodología de diagnóstico basada en el cálculo y reducción de indicadores estadísticos estimados de señales de vibración para la detección de fallas de encendido o por chispa en un motor de combustión interna (MCI). El trabajo realizado por los autores incluye la caracterización de señales de vibración mediante cuatro indicadores estadísticos capaces de modelar la tendencia y describir cambios en las señales. Además, en el método propuesto se introduce el uso de las técnicas de reducción de indicadores estadísticos como análisis de componentes principales y análisis discriminante lineal las cuales tienen la capacidad de reducir la dimensionalidad de la base del conjunto original de indicadores en el dominio del tiempo y obtener representaciones visuales de los patrones característicos de las condiciones de operación evaluadas. El método propuesto se evalúa sobre datos experimentales adquiridos durante la operación normal y con falla de encendido de un MCI en régimen de velocidad baja y alta. El procesamiento de las señales de vibración adquiridas y la aplicación de la metodología de diagnóstico propuesta se hizo bajo el entorno de programación de Matlab. Los resultados obtenidos en patrones característicos bidimensionales presentan claramente la separación de las diferentes condiciones de operación, dichos resultados demuestran que la metodología permite detectar fallas en MCI generadas en el sistema de encendido y que la detección de las fallas se puede realizar de forma efectiva independientemente de la velocidad de giro del motor.
Doenças Emergentes: uma Análise Sobre a Relação do Homem com o seu Ambiente
Authors: Antonio de Carvalho Jair , Regina Farias Teixeira Sandra , Pedrote de Carvalho Márcio , Vieira Valéria , Aguiar Alves Fábio
Published: October 2021

Trabalho com o objetivo oportunizar discussão sobre as doenças emergentes e reemergentes e suas relações com as questões ambientais. Justificando-se pela necessidade de trazer à tona discussões sobre as doenças emergentes e os fatores que as oportunizaram, o mesmo raciocínio se aplica às doenças reemergentes. Doenças emergentes são doenças que vêm surgindo nos últimos anos ou que já existiam e que vem aumentando sua incidência, ultimamente. O Brasil possui uma grande variedade de ecossistemas, envolvendo tanto da fauna quanto da flora, estando este, sujeito à degradação em função de “grileiros” na busca de riqueza fácil e rápida. Ao tratar de doenças infecciosas emergentes e reemergentes, verificam-se dois focos de atenção: o surgimento ou identificação de novos problemas de saúde e novos agentes infecciosos. A rapidez dos meios de transporte leva estes agentes espalharem-se de um continente para outro. Medidas preventivas devem ser tomadas a fim de evitar o aparecimento de novas doenças e o reaparecimento das tidas como erradicadas. Medidas educacionais devem ser aplicadas, a fim de minimizar, se não erradicar o problema das doenças emergentes e reemergentes, garantindo assim uma melhor qualidade de vida
