Thermal barrier coatings (TBCs) are capable of protecting hot-section engine components from the hot gas stream, and thereby can provide improvements in component durability and engine efficiency. Thick TBCs can provide further improvements in durability and efficiency, especially for static components. The main commercial coating methods for TBCs are electron beam physical vapor deposition (EB-PVD) and air plasma spray (APS). These processes have limitations for depositing thick TBCs: for EB-PVD, the deposition rates are low and the cost is high; for APS, durability is reduced with increased thickness. Inframat Corporation, in collaboration with the University of Connecticut, is developing a new plasma spray process, namely, solution precursor plasma spray (SPPS), for the formation of TBCs and also functional films from liquid precursor feedstock, instead of the solid powder feedstock used in conventional APS. SPPS TBCs have many unique microstructural features, including: ultra-fine splats, vertical micro- and macrocracks, micrometer- and nanometer-size porosity. These unique microstructural features provide a TBC with high thermal cycling spallation life and bond strength. These coatings have been made in thickness up to 2 mm and show excellent durability. In this paper we present microstructural characteristics and thermal cycling performance of SPPS-formed 7YSZ thick coatings varying in the range of 0.5-2 mm.

The existing system of price relations between partners in the agro-industrial complex in the domestic milk market has a number of negative trends. The high cost of production and the inability to influence the selling price of raw milk have led to low profitability of agricultural producers. The diversification transformation in the form of the organization of a vertically integrated production system, including the processing of raw milk, will allow the dairy enterprise to reduce costs, manage pricing and receive additional profit, which contributes to the further development and capacity building of the enterprise.

Speaking Against Inequity in the Writing Classroom: Challenging the Performance Paradigm for Undergraduate Oral Presentations
Authors: Luger Moberley , Stensrud Craig
Published: July 2022

Many existing scholarly speaking pedagogies continue to think of oral presentations as performances for an audience rather than dialogic exchanges of research. Such approaches, prominent in Canadian universities, can exacerbate classroom inequities by valuing certain ways of speaking and, by extension, certain speakers: speaking pedagogies, for example, that instruct students to speak “clearly,” dress “professionally,” or even to appear “confident,” can encode prejudices that privilege some voices and bodies over others, perpetuating discrimination based on gender, race, sexuality, language, and culture. This article argues that an equitable scholarly speaking pedagogy will teach students to instead think of oral presentations as opportunities for collaborative knowledge-making. We offer strategies to help students think of scholarly speaking as an integral part of the research process, rather than a stand-alone performance. Drawing on genre-theoretical approaches to academic writing, we argue that this shift can be achieved by using “precedents”—examples of scholarly speaking—to familiarize students with academic oral discourse’s genre conventions, helping students to recognize scholarly speaking as a situated and dialogic research genre. By shifting the goal of academic oral presentations towards cooperative knowledge-making, these strategies at once challenge student prejudices about who can be a “good” speaker and remind students of their responsibilities as audience members, resulting in a more equitable and inclusive classroom environment. To provide a pragmatic example of our approach, we outline the “Classroom Conference” assignment that we developed and evaluated, which uses precedents to prepare students for the oral presentations that are integrated as a step in completing their larger research projects. Analyzing survey data from students who completed this assignment, we recognize its success but also propose strategies for overcoming persisting challenges in getting students to shift their thinking toward an equitable model of scholarly speaking.

The article deals with the unity of the national cultural heritage and historical time in Kazakh documentary films. The purpose of the article is to analyze the features of the use of time in the depiction of the spiritual world, national customs and traditions in the films of documentary film masters OrazAbishev, BakhytGafu-Kaiyrbekov and others. Based on the formal stylistic method, the significance of historical time in documentary films is explored. The author, considering the unity of the national cultural heritage and historical time in the Kazakh documentary, concludes that in the Kazakh documentary film, the reflection of the unity of the national cultural heritage and historical time has gone through several stages of formation, and was closely connected with the social, political phenomena taking place in the country. In conclusion, the stages of the formation of Kazakh documentary cinema are listed from the point of view of reflecting historical time and it is argued that: 1) the first stage is associated with the establishment of Soviet power in Kazakhstan, with the ideology and politics of socialism (1927–1930); 2) the second stage is connected with the reflection of people's memory and history on the documentary film screen in the conditions of the political, social atmosphere of Kazakhstan in the 1960s (1960–1970); 3) the third stage reflects the processes of returning to the origins of national consciousness, people's historical memory (1990–2020).

Congenital Tracheoesophageal Fistula Presenting in an Asymptomatic Adult- A Case Report
Authors: Devabalan Yadsan
Published: July 2022

Introduction: Congenital tracheoseophageal fistula (TEF) involve an abnormal pathological connection between the oesophagus and trachea. Congenital TEF presenting in adults is extremely rare and literature is limited to case series of significantly symptomatic patients. Case presentation: An asymptomatic 41 year-old gentleman presented to clinic, having been diagnosed with a congenital tracheoesophageal fistula 10 years ago on a routine oesophagogastroduodenoscopy (OGD) in Brazil. He underwent a barium contrast swallow revealing contrast in the left main bronchi and significant pooling in the upper trachea. A computerised tomography (CT) scan of the neck and thorax with contrast revealed a small fistula measuring 6mm in diameter between the trachea and the oesophagus at the level of the second thoracic vertebral body. A microlaryngobronchoscopy and examination under anaesthesia visualised a fistula measuring 1.8cm to 2cm superior to inferiorly and similar in transverse dimension, 6-7cm below the level of the glottis. Management and outcome: He opted to have surgical treatment to prevent symptoms developing in the future. A trans-cervical approach was performed, and the oesophageal defect and tracheal defect underwent primary closure with sutures. The oesophageal defect repair was oversewn with the sternohyoid. He recovered well post-operatively but due to the considerable rotation and retraction of the trachea, he suffered a vocal cord palsy. This is improving at the latest follow-up. Discussion: Otolaryngologist (ENT) surgeons need to be aware of asymptomatic adult patients presenting with congenital tracheoesophageal fistulas and the investigation and management options available.

The purpose of the article is to highlight the peculiarities of the overthrow of the hetman's authorities and the beginning of the institutions of the Ukrainian People's Republic in the eastern part of the Podіlska province in the second half of November – beginning of December 1918. The methodological basis of the research consists of research principles of historicism, scientificity, objectivity, general scientific methods: (historical and logical) and special historical methods (narrative and problem-chronological). The scientific novelty of the article is determined primarily by the formulation of the research topic and the complex use of various sources and special works on the problem, which allowed the authors to objectively approach the analysis of the overthrow of the Hetmanate and the establishment of the UPR Directory in eastern Podillya. Conclusions. At the end of  November – beginning of December 1918 in the eastern part of the Podillia province was the overthrow of the Ukrainian State administration and the establishment of power of the Ukrainian People's Republic. The Hetmanate's mistakes in domestic and foreign policy, the lack of a sufficient social base, and the weakness of the security forces made the Ukrainian government vulnerable to radical action. The leading role in overthrowing the Hetman and establishing republican power belonged to former members of the Central Council, nationally conscious Ukrainian intelligentsia and cooperators united in local branches of the Ukrainian National Union, patriotic oriented military and the majority of the population - the peasantry. Eastern Podillya became one of the first Ukraine’s regions  where the power of the Directory of the Ukrainian People's Republic was established. It was important for its approval to eliminate the attempt of the russian white guards to gain a foothold in some counties of Podillya. Eventually, when Vinnytsia was chosen as the temporary seat of the Directory of the Ukrainian People's Republic, the eastern part of Podillya became an important springboard in establishing a new Ukrainian republican government throughout the country.

Published: July 2022

Helichrysum italicum (Roth.) G. Don is an aromatic perennial shrub widespread across the Mediterranean Basin. Plants from this species show a high degree of morphological variability. This research examines morphological variation inside the H. italicum population growing in natural conditions and the correlation between observed morphological traits. Morphometric characteristics of shrub and synflorescence were measured on H. italicum plants from the wild population on the northwestern coast of Istria, at eight locations a short distance apart. Results showed significant variation in the plants’ height and diameter. Pearson’s correlation analysis showed a strong positive correlation between the diameter and height of the shrubs. Hierarchical cluster analysis (HCA) indicates that the observed plants are divided into two clades, based on characteristics measured. Principal component analysis (PCA) showed clear separation of the plants into two groups. Observed characteristics accounted for nearly 76% of the total variance.

Lemongrass leaves are a typical plant of South Kalimantan which contain anti-insecticide, namely secondary metabolites such as alkaloids, saponins, tannins, steroids and triterpenoids. Pediculosis is a disease caused by a tick infection which is still neglected and becomes a health problem. One way to get rid of head lice is to use natural ingredients that contain anti-insecticide substances. This study aims to examine the possibility of using natural ingredients in lime leaves as vegetable insecticides against head lice mortality. The research method used is experimental, with a research design that is a post-test only control group, which measures and compares the mortality variable of Pediculus humanus capitis after being treated with lime leaf juice with concentrations of 10%, 30%, 60%, 100% during 1, 6, 12 and 24 hours and compared them with the negative control group with aquadest and the positive control with pemethrin. The sample of this study was lime leaf extract which was extracted by the method of squeezing using water. From the results of the study obtained the highest percentage of death at 12 and 24 hours with 100% mortality at a concentration of 100%. Based on the results of statistical tests using mortality observation data, the LC99 values were obtained within 1 hour (197.678%), 6 hours (126.055%), 12 hours (89.847%), and 24 hours (60.758%). Based on the results of the analysis of the data obtained, it can be concluded that there is effectiveness of lime leaf juice (Citrus hystrix) on the mortality of head lice (Pediculus humanus capitis) in vitro. Then the juice of lime leaves can be used as an alternative to getting rid of head lice with natural ingredients.

Shoulder dystocia is an unpredictable, unavoidable obstetric condition characterized by a lack of a generally accepted definition, consensus on treatment, and a wide variety of reported incidences worldwide. The purpose of this review is to raise the awareness of obstetricians, gynecologists and residents in the basic principles of labor management for shoulder dystocia and the algorithm of actions proposed by various authors to resolve this emergency obstetric situation. Materials and methods. An analytical review of the special literature on shoulder dystocia from various sources was carried out: conference proceedings, technical reports, journal articles, abstracts and online articles using the Medline, Google Scholar and PubMed databases. Results. Shoulder dystocia is associated with a 1% risk of severe long-term disability or neonatal death. The relative rarity of shoulder dystocia and the lack of standardized management often means that few obstetricians actually have experience with this emergency obstetric problem. To resolve shoulder dystocia, a number of maneuvers are traditionally used, the proposed sequence of which is debatable by various authors. Conclusion. Shoulder dystocia is a highly unpredictable obstetric emergency that requires all practitioners in the delivery room to have a detailed knowledge of the condition and how to manage it.

The purpose — to show the possibilities of the classical X-ray research method for the diagnosis of hernias of the diaphragm esophageal opening. Material and methods. A classical X-ray examination of 138 patients with hiatal hernia was performed. Initially, a study of the chest organs and posterior mediastinum was carried out. A contrast study of the esophagus and stomach with a barium suspension was carried out in a horizontal position of the patient on the back and on the stomach, as well as vertically. Results. Mostly axial hiatal hernias were diagnosed — in 134 patients (97.1%), including 42 (31.3%) with esophageal shortening due to scarring and 92 (68.6%) sliding hernias; signs of intussusception were revealed in 2 cases. In one patient, along with the esophageal shortening, 2 «niches» were identified due to ulceration, which were confirmed by endoscopy. Paraesophageal hernias were found in 4 cases (2.9%), in all four cases the hernias were fixed; in one case, a total hernia with a volvulus of the stomach was diagnosed. In case of 23 (17.1%) patientsaxial hiatal hernias were combined with esophageal or gastric cancer. X-ray findings were confirmed by upper GI endoscopy. Conclusion. The up-to-date, correctly performed X-ray examination made it possible not only to reveal a hiatal hernia, but also to determine its type, to study the function of the esophageal-gastric junction and the presence of complications.

One of the early manifestations of a wide range of the hepatobiliary system diseases in pediatric practice is hyperbilirubinemia syndrome. The greatest concern is caused by conditions accompanied by «direct» hyperbilirubinemia, in which the level of conjugated bilirubin is more than 15% of the total level. Such hyperbilirubinemia is commonly called «cholestatic». Cholestatic liver diseases are very diverse, while underestimation of the pathological process dynamics and delayed therapeutic intervention can lead to death or severe disability. The article presents the clinical and anamnestic features of newborns and young children with the syndrome of «direct» hyperbilirubinemia to optimize the diagnosis and tactics of management, and a clinical case of late diagnosis of biliary atresia with a hyperbilirubinemia syndrome.

Authors:   Samara City Hospital No. 4, SHTEINER M. L.
Published: July 2022

We analyzed 235 nasogastric tube placements (100.00%) in neurological patients with dysphagia due to bulbar syndrome. In 212 cases (90.21%) the installation was successful. A new technique for installing a nasogastric tube is proposed. The essence of this approach lies in the forced advancement through the upper esophageal sphincter by maximizing probe stiffness. The reasons for the failed probe placement were deviated nasal septum, pronounced psychomotor agitation, Zenker’s diverticulum, and pronounced upper esophageal sphincter spasm. Difficulties with intubation that required endoscopic control happened in 15 cases (6.38%). The causes were asymptomatic tracheal intubation, partial paresis of the larynx, lipoma of the epiglottis. The term «difficult nasogastric intubation» was proposed.

The paper deals with an evolutionary method for solving many-objective optimization problems exhibiting a high-dimensionality objective space, which is a challenging problem. An application in the optimal synthesis of Compensation Networks (CNs) of wireless power transfer systems for charging the batteries of electric vehicles is developed. This design problem is characterized by a set of multiple objectives in mutual conflict, which should be simultaneously considered. The optimization aims to the maximization of both the efficiency and the transferred power; a further criterion selects the networks with a suitable profile of impedance vs. frequency. Moreover, the minimization of current and voltage values relevant to inductors and capacitors in the networks, respectively, is pursued. These five design criteria are optimized exploiting the concept of the degree of conflict, which is the core of the proposed method, named “EStra-many”. The method is applied by considering two approaches: the single-objective one, based on the degree of conflict function only, and the bi-objective approach in which the tradeoff between the degree of conflict function itself and another objective function (in turn, the efficiency, the transferred power, the distance of the resonance frequency from the supply frequency, the maximum value of the inductance current, the maximum value of the capacitor voltage, the distance from the Utopia point, and the number of inductors in the CN), is searched for. This way, all in one, seven different optimization problems are solved. The main element of novelty of the paper is a method to solve an optimization problem characterized by a high number of objective functions. In view of this, instead of considering a weighted sum of the objectives, a preference function inspired by the concept of least-conflict solution is formulated accordingly, the preference function is minimized by a cost-effective evolutionary algorithm of lowest order.

In this paper CNNs are used for solving an optimization problem with two different approaches: CNN is used as a surrogate model of the forward problem, inserted in an optimization loop governed by a genetic algorithm, in the first approach, while a CNN is trained for solving directly the inverse problem in the second approach. The case study is the shape design of a magnetic core used for material testing.

Necrotizing enterocolitis (NEC) yet remains a leading cause of morbidity and mortality in premature infants. The developmental deficiency of transforming growth factor-Beta (TGF-β) in the intestine is a risk factor for NEC in premature infants.We aimed to investigate the potential utility of serum TGF-β1 in the early diagnosis and severity assessment of NEC. This prospective case-control study was conducted on 102 VLBW neonates aging less than 32 weeks and weighing less than 1500 gm. They were divided into NEC group of 52 preterm neonates with symptoms and signs of NEC and 50 age and sex-matched neonates without NEC as a control group. All neonates underwent full medical history taking, clinical examination, radiological and laboratory investigations including CBC, CRP, fecal occult blood, and serum TGF-β1. Serum TGF-β1 was tested in NEC patients at the onset of symptoms and signs and 7 days later. Serum TGF-β1 was significantly lower in NEC patients at the onset of symptoms than the control group (P = 0.004) while after 7 days of onset serum TGF-β1 was significantly higher than at the onset of symptoms (P < 0.001). In NEC patients with stage I, TGF-β1 was significantly higher than in NEC patients with stage ≥II (P = 0.027).In conclusion serum TGF-β1 is downregulated in neonatal necrotizing enterocolitis and can be used as a useful biomarker for early diagnosis of NEC and to assess disease severity.

BACKGROUND: Geographical location is known to affect health outcomes; however, evidence regarding whether location affects healthcare for persons suspected to have vestibular dysfunction is lacking. OBJECTIVE: To investigate whether location affects healthcare seeking and outcomes for adults with symptoms of vestibular pathology. METHODS: We assessed for regional disparities associated with demographics, diagnosis, chronological factors, and financial expenditures from Americans who participated in the Vestibular Disorders Association registry (N = 905, 57.4±12.5 years, 82.7% female, 94.8% White, and 8.1% Hispanic or Latino). Respondents were grouped per geographical regions defined by the United States Census Bureau. RESULTS: There were no significant between-region differences for age (p = 0.10), sex (p = 0.78), or ethnicity (p = 0.24). There were more Asian respondents in the West versus the Midwest (p = 0.05) and more Black respondents in the South versus the West (p = 0.05). The time to first seek care was shorter in the Northeast (17.3 [SD = 49.5] weeks) versus the South (42.4 [SD = 83.7] weeks), p = 0.015. The time from the first healthcare visit to receiving a final diagnosis was shorter in the Northeast (46.5 [SD = 75.4] weeks) versus the South (68.9 [SD = 89.7] weeks), p = 0.015. Compared to the Midwest, fewer respondents in the Northeast reported “no” out-of-pocket financial impact, p = 0.039. CONCLUSIONS: Geographical location affects healthcare seeking and outcomes for persons suspected to have vestibular dysfunction.

Pada prinsipnya, pencantuman klausula baku dalam setiap perjanjian baku tidaklah dilarang. Yang dilarang hanyalah pencantuman klausula baku yang memberatkan atau merugikan konsumen sebagaimana yang diatur dalam UUPK. Selama pencantuman klausula baku tidaklah memenuhi kriteria dari 8 (delapan) daftar klausula baku terlarang yang disebutkan di dalam UUPK, maka pencantuman klausula baku tersebut masih dibenarkan dan dibolehkan. Klausula Baku menyebabkan pihak konsumen tidak dapat menentukan keinganannya dengan bebas. Dalam pusat perbelanjaan ditampilkan klausula dengan kalimat “Barang yang sudah dibeli tidak dapat ditukar kembali”. Atau “Barang yang tidak diambil 2 (dua) minggu, kami batalkan atau menjadi milik pihak manajemen”. Dan “barang pecah berarti membeli”. Permasalahan dalam penelitian ini adalah: 1) bagaimana perlindungan hukum konsumen terhadap perjanjian baku yang dibuat pelaku usaha?, 2) bagaimana akibat hukumnya perjanjian baku yang dibuat pelaku usaha?. Tujuan penelitian ini adalah untuk menganalisa perlindungan hukum konsumen terhadap perjanjian baku yang dibuat pelaku usaha, untuk menganalisa akibat hukumnya perjanjian baku yang dibuat pelaku usaha. Penelitian ini penulis gunakan penelitian penelitian hukum normatif, teknik analisa data dengan menggunakan analisis kualitatif yaitu data yang penulis analisis menjelaskan dengan secara deskriptif dan kata-kata yang mudah dimengerti, dengan ditarik kesimpulan dengan menggunakan ataupun yang sejenisnya, kemudian ditarik kesimpulan secara deduktif. Kesimpulan dari penelitian ini yakni sudah tercantum atau dituangkan dalam bentuk undang-undang, yaitu Undang-Undang Nomor 8 Tahun 1999. Hak-hak tersebut sudah diakui keberadaannya dan memiliki kepastian hukum yang diatur dalam undang-undang positif. Upaya hukum yang dilakukan oleh konsumen yang merasa dirugikan bisa menggunakan pasal-pasal dalam Undang-Undang Nomor 8 Tahun 1999 ini, namun dalam kaitannya perjanjian baku yang dibuat oleh pelaku usaha sekarang sudah dibuat dalam peraturan hukum.
