The object of the research is oxidized nickel ores from the Kulikovskoye deposit (Southern Urals) – non-conforming nickel-containing raw materials. The work is devoted to the study of chemical and phase composition to substantiate the choice of the method of processing this material in order to obtain valuable inorganic substances in demand in the chemical and metallurgical industries: oxide and (or) magnesium nitrate, iron and nickel containing concentrates, silicon dioxide. The chemical composition of ore demonstrating the feasibility of developing a technology for its complex processing is presented. X-ray phase analysis showed the presence of silicates of the serpentine group (lizardite-1M and lizardite-1T) and the group of spinelids (magnesioferrite) in the oxidized nickel ores of the Kulikovskoye deposit. A literary analysis suggested the presence of other hydrosilicates (antigorite, chrysotile, nimite, talc, revdinskite, clinochlore, etc.). IR spectroscopic analysis was performed to confirm the phase composition. A thermogravimetric analysis was performed, which makes it possible to determine the conditions for the preliminary preparation of ground raw materials. To determine the mechanism of thermal decomposition of ore in air, intermediate products were obtained at temperatures of 600, 700 and 900 °C. According to X-ray diffraction, IR and Raman spectroscopic analyzes, at 600 °C, the removal of OH groups, water molecules and the destruction of the crystal lattices that make up the mineral ore with the formation of oxides (FeO, SiO2, MgO) begins. At 700 °C, island silicates are formed: forsterite Mg2SiO4, larnite Ca2SiO4. At 900 °C, the interaction between silicates continues with the complication of the composition of functional groups. Based on the described properties of minerals and previous work on the hydrometallurgical technology of processing oxidized nickel ores and metal-containing silicate raw materials in order to obtain inorganic substances, nitric acid is proposed as a leaching agent.

Published: March 2021

The effect of water-acetonitrile and water-methanol eluents composition on newly synthesized benzimidazole derivatives sorption by supercrosslinked polystyrene (SCP) using high performance liquid chromatography was studied. It is shown that the nature of the organic modifier affects on the considered biologically active compounds sorption. The angular coefficients of the Snyder-Sochevinsky equation, characterizing the number of organic modifier molecules, displaced by one molecule of sorbate, for benzimidazole derivatives, are calculated. The angular coefficients was calculated from the dependence, characterized by a high coefficient of determination. The article demonstrated that the Snyder-Sochevinsky model could be used for describing of all studied compounds sorption in the system “SCP – water-methanol eluent” and for describing of volume sorbates with hydrophobic substituting groups sorption in the system “SCP – water-acetonitrile solution”. The value of the slope of the Snyder-Sochevinsky equation of benzimidazoles sorption from water-methanol solutions is higher than that from water-acetonitrile solution; this fact indicates a lower elution power of the water-methanol eluent in compare to water-acetonitrile eluent. The Snyder-Sochevinsky model is not fulfilled in the concentration range from 75% to 85% of acetonitrile for small volume benzimidazole molecules containing hydrophilic amino and hydroxymethylene groups in the «SCP – water-acetonitrile eluent» system. The composition of the mobile phase influence of benzimidazoles sorption was studied. It is demonstraited the relationships between volume fraction of the organic modifier increase and decreases of benzimidazoles sorption.

The metal blind holes acting as interconnectors allow significantly reduce the number of layers, increase the efficiency of trace and decrease interference between the holes and signal conductors in the high frequency printed circuit boards. In this work, a comparative assessment of the conditions of direct and electrochemical metallization blind holes with diameters: 0,2; 0.25; 0.3; 0.4; 0.6; 0.8; 1.0 mm and a drilling depth of 0.5 mm located on experimental four-layer multilayer printed circuit boards, differing in the method of applying a conductive and copper coating was carried out. It has been established that in case non-fulfillment of mandatory conditions for the production of blind holes, in particular the aspect ratio is less than or equal to unity, incomplete metallization of the walls and especially the bottom of the holes is observed. The ways of combining the processes of direct and electrochemical metallization of holes, which provide the required thickness and quality of the copper coating at reduction of general duration of operations have been proposed based on the experimental data obtained during the work with multilayer printed boards. Also it has been established that the joint placement of blind holes with a smaller and larger diameter on one multilayer printed circuit board requires a more long direct metallization in combination with electrochemical at low values of current density. Copper films deposited on the walls of the holes and on the surface of the contact pads, regardless of the proposed way of metallization, have a highly dispersed structure. The composition of the palladium catalyst layers has been studied by energy dispersive analysis. The conductive coating on the blind hole’s walls contains between 1.55 and 6.77 at.% palladium.

Published: March 2021

Introduction: Massage has shown promise in reducing symptoms related to dissociation and anxiety that can exacerbate chronic pain and suffering. The combat wounded, veteran population is increasing and requires a multidisciplinary approach for comprehensive treatment. This case study examines massage therapy use to improve veteran combat injury rehabilitation and recovery experience through purposive, retrospective, and comprehensive SOAP note review. Methods: A 31-year-old White male received seven, 60-min, full body massages for combat related shoulder injury complications incurred approximately six years before presentation. The right shoulder sustained a broken humeral head and complete dislocation during a defensive maneuver in a life-threatening attack. This case study utilized data from three different assessments: goniometric measurements for shoulder range of motion, observation and documentation for environmental comfort behaviors, and client self-report for treatment goal attainment. Six weekly, full body, 60-min massages were completed sequentially. A follow-up 60-min treatment was completed at Week 8. Treatment to the injured area included focused trigger point therapy, myofascial release, and proprioceptive neuromuscular facilitation to the neck, shoulder, and chest. Results: Total percent change for active flexion, extension, abduction, adduction, internal rotation, and external rotation were 12.5, 150, 40, 167, 14.3, and 0%, respectively. Total percent change for passive flexion, extension, abduction, adduction, internal rotation, and external rotation were 63.6, 350, 66.7, 450, 133, and 77.8%, respectively. Environmental comfort behaviors were reduced. Client treatment goals were attained. Conclusions: Massage therapy provided meaningful benefit to a combat injury for a veteran with PTSD.
Que négocie-t-on en Syrie ?

Published: March 2021

Que négocie-t-on (encore) en Syrie ? Alors que le conflit dure depuis bientôt une décennie, des négociations internationales, de nature et de format variés, se poursuivent néanmoins. Le présent article vise à démêler l’écheveau des négociations qui prennent place autour du conflit syrien. Il montre comment des questions en apparence simples, comme les raisons qui poussent à négocier, les partenaires et les objets des négociations, et les limites du négociable sont investies différemment selon les instances et les acteurs. La mise en regard des négociations humanitaires et politiques est utile pour penser la variété des usages et des fonctions des négociations en Syrie. Le cas syrien témoigne finalement de la façon dont les négociations peuvent devenir une partie intégrante du conflit, interagissant y compris avec sa dimension militaire, révélant ainsi les tensions et les oppositions structurantes entre les multiples acteurs engagés.
Nailing it à la Saudi: Satire and the Subject in Times of Crisis
Authors: Alaoui Khadija El , Alajlan Azza Ibrahim , Pilotti Maura A. E.
Published: March 2021

The present study first explores the phenomenon of Saudi satire on YouTube since 2010, and then focuses on the popular Masāmīr (Nails), an extensive series of cartoons posted on YouTube. Along with other comedy shows, Masāmīr not only exemplifies the uses of satire by those who practice and consume it, but also unravels what Janet Roitman and Achille Mbembe describe as the subject in times of crisis (1995). Namely, laughter is read as a means of expressing unbearable experiences in the nexus of Saudi society and a larger virtual community, all embedded in an autocratic context, including an internalized authoritarian epistemology. Satirical videos stage a society in crisis: forces of lethargy, connivance, and violence are entangled with aspirations for agency and change. Thus, the artists’ work allows us a glimpse into an ambivalent subjectivity. They are critically looking into themselves and their society, at times confessing their helplessness and at other times colluding with the existing power structure, a move that redeems the state and reinscribes it within the national narrative of the ultimate savior.
The Islamic veil in the Gulf and Arabian modernity: A qualitative study on female managers
Authors: Lacheret Arnaud , Farooq Mohammad Omar
Published: March 2021

The aim of this study is to identify the feelings of female managers in the Gulf region about the Islamic veil, and the meanings they attribute to this veil, a key element of Arabian modernity and of the evolving gender-inclusive business environment. This three-year study, conducted in the Gulf region focused on the values of Arabian female managers after their sudden admission into the professional world, especially since the early 2000s. Twenty women participated in the qualitative study, in which semi-structured interviews were used to question interviewees about their values, notably the influence of religion on their daily behavior and way of thinking. The discussion is supported by both anthropological data and religious sources. A significant proportion of the questionnaire focused on the interviewees’ religious feelings, and in particular on a crucial and controversial subject in Europe: the Islamic veil. The main findings suggest that although the Islamic veil has religious significance for the interviewees, they consistently privileged the concept of free choice, showing that female managers in the Gulf region consider freedom of choice as a form of symbolization of religious obligation, and this view is one of the essential markers of Arabian modernity.

Authors: Pandey Ashish , Badal Neelendra
Published: March 2021

Machine learning-based intrusion detection system (IDS) is a research field of network security which depends on the effective and accurate training of models. The models of IDS must be trained with new attacks periodically; therefore, it can detect any security violations in the network. One of most frequent security violations that occurs in the network is denial of service (DoS) attack. Therefore, training of IDS models with latest DoS attack instances is required. The training of IDS models can be more effective when it is performed with the help of machine learning algorithms because the processing capabilities of machine learning algorithms are very fast. Therefore, the work presented in this chapter focuses on building a model of machine learning-based intrusion detection system for denial of service attack. Building a model of IDS requires sample dataset and tools. The sample dataset which is used in this research is NSL-KDD, while WEKA is used as a tool to perform all the experiments.

Authors: Gangwar Pavan , Prajapati Sandhya , Fernandez E. , Singh Ashutosh Kumar
Published: March 2021

Conventional generation is the most reliable option to meet the increased energy consumption in terms of operating performance. However, the increased greenhouse gas emission is a major threat from the conventional generating units due to fuel pollution. Although to meet the increased energy consumption, reliably conventional generating units are inevitable. So the government has taken the initiative to shut down the conventional generating units with higher pollution levels than the defined norms. This imposes the overall load burden to the other state generating units. As Delhi is sufficiently rich with solar radiation, the chapter proposes the solar PV installation to meet the generation gap of shutdown units.

Authors: Pulle Mohan Venkatesh , Asaf Belal Bin , Puri Harsh Vardhan , Bangeria Sumit , Bishnoi Sukhram , Kumar Arvind
Published: March 2021

Objectives:

The diagnosis of traumatic transection of main bronchus is often delayed, resulting in attempts at surgical repair sometimes even months after the injury. Our aim is to analyze the factors affecting surgical outcome in patients undergoing lung preserving bronchial re-implantation for bronchial transection.

Materials and Methods:

This is a retrospective analysis of prospectively maintained data of 10 cases of traumatic transection of main bronchus who underwent bronchial re-implantation at a tertiary thoracic surgery center in India. Patients were divided into two groups based on their total length of hospital stay. Occurrence of postoperative complications and/or hospital stay >7 days were considered poor surgical outcomes.

Results:

Out of 10 patients, 6 were left main bronchus transections and 4 right main bronchus transections. The male-female ratio was 7:3. Right-sided bronchial injury and higher preoperative Injury Severity Score (ISS) were associated with poor surgical outcomes (P < 0.01). These patients also had significantly higher anastomotic complications, chest tube duration, and prolonged postoperative air leak. Age of the patient, preoperative hemoglobin or albumin levels, and time of referral did not influence the surgical outcomes.

Conclusions:

Poorer surgical outcomes were observed in patients who had right-sided main bronchus injury and higher ISSs. Time of referral did not influence the outcome. This study is limited by small sample size and retrospective nature. As no single center will have large numbers of this uncommon injury, multicenter pooled data are needed to re-affirm the findings of this study.
Clinical analysis of adenovirus postinfectious bronchiolitis obliterans and nonadenovirus postinfectious bronchiolitis obliterans in children
Authors: Huang Fei , Ma Yu-Cong , Wang Fang , Li Ya-Nan
Published: March 2021

Background and Objective:

Postinfectious bronchiolitis obliterans (PIBO) is an uncommon and severe form of chronic obstructive lung disease in children. Adenovirus (ADV) is the main pathogen of PIBO in children. However, the risk factors of ADV-PIBO are not fully understood. This study aims to analyze the clinical characteristics of PIBO caused by ADV and compared with non-ADV-PIBO.

Materials and Methods:

A retrospective study of children under the age of 14 years diagnosed PIBO was performed in 56 ADV-PIBO cases, 29 non-ADV-PIBO, and 39 healthy controls to determine clinical characteristics of PIBO.

Results:

There was no difference between ADV-PIBO and non-ADV-PIBO cases in gender, age, individual and family atopy or history of asthma, and previous history of wheezing and no difference in the clinical manifestations and signs between the two groups. However, the hospital stay, duration of ventilator use, and multifocal pneumonia incidence of ADV-PIBO group have a significant differences compared with non-ADV-PIBO. Notably, inflammatory markers lactic dehydrogenase (LDH), interleukin 8 (IL-8), and interferon-gamma (IFN-γ) were significantly increased in PIBO patients, and those expressed in ADV-PIBO patients were higher than those in non-ADV-PIBO patients. In addition, ADV-PIBO children required a longer duration of oral prednisone and azithromycin than non-ADV-PIBO cases.

Conclusions:

Compared with non-ADV-PIBO, ADV-PIBO has a longer hospital stay, longer duration of ventilator use, increased LDH, IL-8, and IFN-γ expressions, and longer duration of oral prednisone and azithromycin treatment. Further research is needed to determine why PIBO caused by ADVs are more severe than those caused by other pathogens.

Turbojet Engine Parameters Calculation Based on Fuel Flow and Exhaust Gas Temperature
Authors: Novakovic Neno
Published: March 2021

The aircraft jet engine is one of the most complex multivariable systems with multiple inputs and multiple outputs. To attempt to optimize control functions or to address diagnostic problems, a detailed knowledge of all jet engine design parameters and performances is required. Although jet engines have been around for almost a century, there are only a few companies in the world presently designing and manufacturing them; as such these companies possess detailed knowledge of all relevant design characteristics and performance parameters. In the event where jet engine technical details are unknown, or only a few of them are known from manufacturer’s catalogues, the challenge becomes how to calculate and extrapolate critical performance parameters based on only fuel flow, jet exhaust temperature and total thrust. The brief engineering concept of calculation steps presented herein has the goal of identifying unknown turbojet engine parameters and design characteristics based on limited measurements and test data obtained at static conditions and single operating point. Test data included steady state fuel flow, turbine gas exit temperature and total jet engine thrust. For the purpose of jet engine parameters estimate and identification, the Rolls-Royce VIPER 11 Mk 22-6 jet engine was used. Calculated and estimated jet engine design parameters were evaluated and compared with measured parameters under the same initial conditions. The results show that calculation and identification processes are accurate with an overall error of less than 1 percent. The presented numeric algorithm combined with off design parameters calculation, can be used in jet engine health monitoring and fault detection processes.
A Risk Assessment of an Airborne Disease inside the Cabin of a Passenger Airplane
Authors: Horstman Ray , Rahai Hamid
Published: March 2021

Analytical calculations along with computational fluid dynamic (CFD) simulation of a Boeing 737-600 cabin with a single infector (a passenger) has been performed using a passive scalar gas with particle sizes similar to the sizes of influenza virus laden particles which are assumed to be comparable to the sizes of the Coronavirus laden particles. CFD results of the virus transport and concentration were used in conjunction with the Wells-Riley (WR) quanta estimation from two well-documented cases of influenza infection on airplanes (with the assumption that the infections were primarily from the airborne route), to estimate the infectious rate. The risk of infection is estimated by the quanta of viruses inhaled assuming 0.3 CFM of passive scalar gas corresponds to 1267 viruses/minute released. Results indicate that with a 3-hour flight, the risk of infection is nearly 50% for those sitting in the vicinity of the infector which is equal to 2-3 infections for 131 passengers.

A comparison to a documented COVID-19 case shows that 4 symptomatic passengers could infect 2 others if the COVID-19 virus infectiousness lays mid-range of the influenza infectious doses.

The use of masks could dramatically reduce the risk of airborne infection. When the infector wears a mask the virus concentration is reduced for all other passengers and the mask is more effective at catching the virus droplets before they dry out in the cabin air. A significant reduction in virus transport and the infectious rate was observed with the N95 mask for a 3-hour flight.

With 2.9-ft social distancing (vacant middle seat) resulting in 2/3 cabin passenger capacity, the ventilation rate per person is increased by 45% and the risk of infection was dropped by more than 48%.

Range of Motion Outcomes Post Cruciate-Retaining vs Posterior Stabilized Total Knee Arthroplasty: A Retrospective Multi-Centre Cohort Study
Authors: Yausep Oliver Emmanuel , Saleh Ifran , Tanujaya Adryan
Published: March 2021

Background: The outcome for TKA (total knee arthroplasty) upon whether the posterior cruciate ligament is preserved with cruciate retaining (CR) prostheses or sacrificed with posterior stabilized (PS) prostheses are still debated between studies. Materials and Methods: We included a total of 144 knees operated with cemented fixed bearing primary CR or PS TKAs. Independent t-tests were conducted for the outcomes and possible confounding variables between groups where relevant, with analyses using Chi-squared tests for nominal data. Results: Operation on patients with age of lower than 65 years predicts increased intraoperative bleeding volume (p = 0.037), pre-operative range of motion (ROM) of less than 90 degrees was a predictor for better improved post-operative ROM (p 0.001) and PS prostheses is superior to CR in terms of ROM improvement (p = 0.04), however with both groups achieving similar maximum ROM (p = 0.308). Conclusion: Improvement of ROM is increased by the use of PS prostheses compared to CS prostheses, with pre-operative ROM as a possible confounding factor and the maximum ROM achieved for both prostheses being similar. Lower age of the operation is also related to increased intraoperative bleeding

Published: March 2021

Background: This study examines the comparison of biomechanical strengths of three kinds of the most familiar implants available in Indonesia: conventional and locking sacroiliac plates and screws, also iliosacral screws. Despite the common thought that iliosacral screws are preferred compared to conventional plates and screws due to its biomechanic superiority, this study tested whether the locking plates and screws could offer an alternative.Materials and Methods: This study was an in vitro experimental study with a Randomized Post Test - Only Control Group Design using pelvic bones from male cadavers aged 20-50 y.o. Twelve samples were divided into three treatment groups and one control group. Group P1 was fixed with two conventional plates, P2 was fixed with two locking plates, P3 was fixed with two iliosacral screws, and control group K with sacroiliac joint was intact. Each group was given an increasing load until a vertical shift of the sacroiliac joint ≥ 2.0 mm was obtained.Results: The average force load for 2 mm displacement among the fixation systems being tested shows a statistically significant difference (p0.05). Load failure force for 2 mm displacement in the locking plate and screw group has the highest average (591.33 ± 56.08 N) compared to the iliosacral screw group (583.67 ± 73.56 N) and conventional plate and screw group (574 ± 106.05 N).Conclusions: Biomechanically, the fixation system using two locking anterior sacroiliac plates and screws is more stable than the iliosacral screws and conventional sacroiliac plates and screws.

Situating Narrative Construction within Social Dynamics and Context to Create Complex Meaning: A Review of the Book Analyzing Narrative Reality
Authors: De Oliveira Becky
Published: March 2021

Analyzing Narrative Reality (Gubrium & Holstein, 2009) examines how stories are constructed for different purposes in a variety of social situations and aims to provide a framework for analysis "oriented both to the internal and especially to the external organization of stories" (p. 2). The authors are keen to create an understanding of how stories emerge and why they are constructed, confident that these factors are vital to creating good stories-"continuously unfolding accounts, whose extensions move in many directions" (p. 228) and that go beyond the boundaries of text. The book covers narrative reality, narrative work, narrative environments and narrative adequacy partly by using Stanley from Shaw's (1930) study, The Jack-Roller, to examine how narratives are socially constructed. Empirical examples and an emphasis on interdisciplinary endeavors are intentionally utilized to create an accessible book for readers from a variety of disciplines.

Bioética e Biodireito: uma resposta à manipulação da natureza e da pessoa humana
Authors: Rampazzo Lino
Published: March 2021

Este artigo pretende questionar o rumo atual da ciência e da tecnologia que chegou a um ponto de ruptura, por colocar em risco o futuro da natureza e do mesmo homem; e apontar as recentes disciplinas da Bioética e do Biodireito como respostas a tal problemática. Para isso apresentam-se, antes, as quatro eras do desenvolvimento técnico da humanidade: a da caça e da pesca, a agrícola-pastoril, a industrial e a tecnológica da informática. Nesta última se encontra o maior risco de manipulação da natureza e do ser humano. Por isso aparece o questionamento ético da ciência e da tecnologia. Por um lado, a ciência nasce de uma ética do saber e do fazer pelo fato da vontade humana sentir-se chamada a lançar-se na conquista do cosmo e na descoberta do mistério que envolve a mente humana. Por outro, porém, esta ética ordenada e positiva dependerá não apenas dos fins para os quais se dirige a conquista, mas também dos modos e dos meios: teleologia e deontologia deverão estar juntas durante este caminho. Neste pano de fundo aparece a recente disciplina da Bioética, como uma “ponte” entre o saber tecnológico e o saber humanista. Seus princípios são: a defesa da vida física, a liberdade e responsabilidade, a totalidade, a socialidade e subsidiaridade; ou, com outra terminologia: os princípios do benefício, da autonomia e da justiça. Aparece, então, como aplicação da Bioética, o Biodireito, cujo objeto de análise são princípios e normas jurídicas que têm por fim imediato criar, resguardar, transferir, modificar ou extinguir direitos decorrentes de relações entre indivíduos, entre indivíduos e grupos, e entre esses com o Estado, quando essas relações estiverem vinculadas ao início da vida, ao seu transcurso ou ao seu término. O estudo se realiza através de uma pesquisa bibliográfica.

Authors: Cardoso Maione Rocha de Castro , Cardoso Gil Célio de Castro , Droulers Martine , Bursztyn Marcel
Published: March 2021

A política relacionada à proteção do ambiente e dos recursos naturais vem adquirindo importância crescente desde os anos de 1980, primeiramente nos países desenvolvidos, como a França, exigindo-se uma ação mais firme dos governos quanto a proteção ambiental. Assim, os objetivos deste artigo são: apresentar os chamados empregos verdes; estudar as politicas adotadas na França em contraponto ao Brasil; apontar os impactos sobre a geração de renda como um dos fatores que contribuem para a sustentabilidade do desenvolvimento, destacando-se, sua importância para a preservação, conservação e manutenção do meio ambiente. Utilizou-se pesquisa bibliográfica e documental, além de dados secundários disponibilizados por  instituições governamentais da França e do Brasil. Conclui-se que é possível fazer algumas aproximações entre as ações ocorridas na França e o caso brasileiro, como: quanto à evolução no seu desenvolvimento, na forma de governo (ou governança) e na ocupação do território e, a partir disto, adaptar aquela experiência com a nossa realidade, lembrando a importância do planejamento público e da participação da sociedade.
Estudo sobre as noções práticas da tolerância na contemporaneidade
Authors: De Sousa Francisco de Jesus Silva , Limas Yasmin Maciel
Published: March 2021

Este estudo teve como objetivo discutir as noções e as práticas da tolerância na contemporaneidade utilizando, como procedimento metodológico, a pesquisa bibliográfica. A pesquisa mostra que há certo consenso acerca da tolerância ser entendida como o reconhecimento do direito que outras pessoas têm de abraçarem diferentes crenças, visões de mundo, modos de vida, bem como modos de expressá-los. No entanto, a partir da análise do contexto contemporâneo, especificamente o brasileiro, é possível encontrar diferentes casos em que a busca pela tolerância, sustentada pela noção pouco aprofundada dela, tem contribuído para que as práticas intolerantes se perpetuem.
Morphology and fracture effects of the hamulus pterygoid: a literature review of the last 49 years
Authors: Strini Polyanne Junqueira Silva Andresen , Strini Paulinne Junqueira Silva Andresen
Published: March 2021

The hamulus pterygoid consists in a relevant anatomical structure, important for fixation of several tendons and muscles, keeping the integrity of soft palate and pharynx. A literature review was conducted in order to investigate the morphology and effect of hamulus pterygoid fracture in clinical manifestation and its relationships with other orofacial components. A literature search was conducted, using Pubmed and Bireme data bases, and covering the time period 1970 to 2019. The Key words for the research were hamulus pterygoid, pterygoid fracture and hamulus pterygoid fracture, resulting in 440 articles, being 41 initials selected. Among them, just 31 were included in the analysis and 08 of the articles were not available through our library system or were in volumes before our holdings began. The remaining were excluded when they weren’t in English idiom, or when didn’t talk about morphological, functional or damages in the hamulus pterygoid. In this context, it may be observed a scarce number of works about the hamulus pterygoid, with doubts in relation to its morphology and functional aspects and how diagnostic its lesions and consequences.
O uso de tinta veneno em embarcações de pesca e turismo: efeitos da poluição por microplástico nas águas marítimas da Baixada Santista
Authors: Severo Fagner Evangelista , Matos Maria Cristina Pereira
Published: March 2021

Este estudo realizou um levantamento da problemática da poluição por microplásticos e compostos organoestânicos, como o Tributilestanho (TBT) ou Trifenilestanho (TPhT) presentes nas tintas utilizadas nas embarcações de madeira. Para identificar a presença de tais poluentes este estudo empregou a metodologia de caráter exploratório, de cunho qualitativo, através de pesquisa de campo junto aos pescadores e donos de embarcações de pesca na Vila da Barra do Una, Peruíbe, SP, no entreposto de pesca de Santos, SP e de embarcações de passeio no píer do Saldanha da Gama, também em Santos, SP. Os resultados obtidos permitiram observar que são utilizadas tintas venenosas para coibir a ação de microorganismos incrustantes que se fixam aos cascos das embarcações e resultam em problemas para os usuários e para a vida marinha. Além disso, identificou-se que no processo de raspagem dos barcos para procedimentos de novas pinturas, partículas de plástico derivadas das tintas removidas são descartadas no mar, favorecendo a contaminação das áreas. A constatação de que esses tipos de embarcações marítimas são todas cobertas por tintas venenosas que deixam resíduos de plástico tóxico no ambiente, indicam a necessidade de novas pesquisas que visem desenvolver tintas anti-incrustantes para os cascos de embarcações que não contribuam para a poluição marinha.
Psicoterapia, neuroplasticidade e o funcionamento cerebral
Authors: Bruggmann Mario Sergio
Published: March 2021

Trata-se de uma revisão narrativa da literatura, cujo objetivo é descrever a relação entre psicoterapia, neuroplasticidade e o funcionamento cerebral. Ao realizar as buscas em diferentes bases de dados, evidenciou-se que as psicoterapias são emergentes de um longo processo histórico, associado à construção do conhecimento científico. Constituem um recurso terapêutico empregado na área da saúde, se apresentando sob diferentes concepções teóricas e modelos de atuação, estando indicadas ao tratamento de transtornos mentais e problemas de origem emocional, como método de escolha ou adjuvante a outras formas de tratamento. O curso científico traçado por pesquisadores para compreender o funcionamento cerebral associado à psicoterapia, remonta uma trajetória de significativos progressos, dentre eles o conhecimento sobre a neuroplasticidade, que faz menção à relação entre a experiência, fatores sociais, aprendizado e cérebro. Considera-se, portanto, se que a psicoterapia tem papel preponderante na modificação do funcionamento cerebral por meio da plasticidade neuronal, conforme evidenciado por estudos de neuroimagem. Para tanto, sugere-se que sejam realizadas mais investigações sobre o impacto da psicoterapia no funcionamento cerebral, especialmente, para refinar o arsenal científico que abrange os transtornos mentais e a prática na clínica do psicoterapeuta.
ISOLATION OF ANTIBIOTIC PRODUCING BACTERIA FROM POND SOIL, GUDLAVALLERU
Authors: Sharmila Donepudi
Published: March 2021

Soil being a major reservoir for microorganisms it is a source of interest for isolation of antibiotic producing organisms. The emergence of antibiotic resistance and need for better, broad spectrum antibiotics is always in high demand. In the present study, antibiotic producing bacteria were isolated from a local soil sample. Total ten soil samples were collected from local pond aseptically and subjected to serial dilution. Crowded plate technique was employed for the isolation of the colony. Total five isolated were isolated which exhibited zone of inhibition around the colony. The isolated colonies were subjected to morphological, microscopical and biochemical characterization. All five colonies were found to be gram positive, non-sporulating organisms and found they belong to the Actinobacteria class. The isolated colonies were subjected to screening for antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis and Yeast by perpendicular streak method. The primary screening results conclude that except one colony all have good antimicrobial activity. One colony found to be highly potential activity which had inhibition towards gram positive, gram negative, sporulating and fungal activity. This study may contribute in providing information on the antibiotic producing microorganisms in soil. Further characterization, purification, and structural elucidation are recommended to know the novelty, quality and commercial value of these antibiotics.
