CFD SIMULATION OF HEAT TRANSFER WITH SPIRAL-WIRE DISPLACEMENT ON THE PIPE
Authors: Oliinyk V.S. , Krukovskyi P.G. , Deineko A.I. 
Published: December 2021

The results of the study of the intensification of the heat transfer process under forced air convection in the annular gap of a pipe-in-pipe heat exchanger with a spiral-wire intensifier located near the outer surface of the inner pipe are presented. The intensifier does not touch the pipe surface. The height of the wire of the intensifier is taken as 1.5 mm. The change in the winding pitch varied within the range of 12-20mm.
Boundary conditions of the first kind + 20 ° C are set on the inner surface of the inner pipe. The temperature of the air moving in the annular gap is 300 ° C. The air velocity varied from 6 to 15 m / s.
For the CFD model of a pipe-in-pipe heat exchanger, the use of a computational grid with 4.7 million elements is justified. The CFD model was validated using literature data.
Based on the analysis of the ratio of the intensified Nusselt number to the Nusselt number for a smooth pipe, a 1.7-fold increase in heat transfer was found for Reynolds numbers from 5000 to 7000. This result is explained by the periodic destruction of the boundary layer along the pipe. With a further increase in Reynolds numbers to 13000, the intensification of heat transfer decreases from 1.7 to 1.3, which is explained by an increase in the vortex zone immediately behind the wire and the appearance of recirculation zones that make a minimum contribution to heat transfer.
It has been determined that the spiral-wire intensifier with the maximum possible step of 20 mm contributes to the greatest increase in heat transfer by 1.7 times and has the smallest coefficient of hydraulic friction of 0.076-0.06 for the studied range of Reynolds numbers.

Spinal metastasis of parotid acinic cell carcinoma followed by intradural extramedullary recurrence: illustrative case
Authors: Yuan Po Hsiang (Shawn) , Grassner Lukas , Fisher Charles , Dea Nicolas 
Published: December 2021

BACKGROUND
The diagnosis and management of acinic cell carcinoma (ACC) is often challenging given its similarity to benign tumors, high incidences of late recurrence and distant metastasis, and tendency to be resistant to systemic chemotherapy. A primary parotid ACC resulting in an intradural extramedullary mass has not been reported.

OBSERVATIONS
The authors describe such a case that presented as a progressive cervical myelopathy 29 years after initial diagnosis. The tumor, located at the C2–C3 level, infiltrated the dura and contained both extradural and intradural components. This occurred 18 months after the incomplete resection of an extradural metastasis at the same location.

LESSONS
Although intracranial and extradural metastases of various primary malignancies are well reported, secondary spinal intradural malignancies are rare. As a result, there are no established guidelines for the surgical management of intradural extramedullary metastases and prognosis may be difficult to establish. In this case, treatment options were limited because systemic therapy options had been exhausted and repeated radiation to the area was not recommended. We report on this case to highlight the clinical course of a rare local recurrence after spinal metastasis leading to an intradural extramedullary tumor and to show that surgical intervention can lead to improvement of neurological symptoms.

BACKGROUND
Сervicomedullary ependymoma (CME) is a rare tumor of the central nervous system. The CME treatment strategy is insufficiently represented in the literature and is a complex task for neurosurgeons.

OBSERVATIONS
The authors describe an infrequent case of a large multisegmental CME that extended from the medulla oblongata to the cervical spinal cord at the level of the sixth cervical vertebra in a 21-year-old female. Neurological disorders presented with headache, dysphagia, hypophonia, and weakness in the limbs. Subtotal removal of the tumor was performed according to intraoperative neurophysiological monitoring (IONM) results. A wait-and-see approach with patient follow-up was chosen.

LESSONS
Total tumor removal of the CME is the most important favorable prognostic factor. Subtotal resection can be considered if the borders of the tumor are unclear and the result of IONM is unfavorable. The role of postoperative radiation therapy in the case of subtotal removal of the tumor remains controversial.

GYULA NÉMETH’İN KÜÇÜK ASYA GEZİSİ İLE İLGİLİ MEKTUPLARI VE TÜRKOLOJİ AÇISINDAN ÖNEMİ
Authors: ÇOLAK Melek 
Published: December 2021

Macaristan Türkoloji’sinin seçkin siması ve aynı zamanda dünyaca ünlü Macar Türkolog Gyula Németh, (1890-1976) bilim dünyasına birçok eser kazandırmış ve kendi ekolünü yaratmış bir bilim adamıdır.

Küçük yaşlarda Türkoloji’ye ilgi duyan Gyula Németh, Türkçeyi kendi çabalarıyla öğrenmiş ve bu bilgisini geliştirmek istemiştir. İlki 1907 yılında henüz lise öğrencisi iken İstanbul’a yaptığı ilk gezisinin dışında, bir yıl sonra tekrar Türk topraklarına gelmiştir. Bu sefer yaptığı plan gereğince İstanbul’dan uzakta, Küçük Asya topraklarında araştırma ve inceleme imkânı bulmak için İzmir ve Aydın çevresini gezmiştir.

Gyula Németh’in Küçük Asya gezisi ile ilgili, kendisinin Macaristan’a döndükten sonra kaleme alıp yayınlattığı gezi hatıralarının dışında çok az bilgi bunmaktadır. Ancak onun, henüz ne Macaristan’da ne de Türkiye’de gün ışığına çıkmamış ve yayınlanmamış Macar Etnografya Müzesi Arşivi’nde bulunan şahsi mektupları Németh’in bu gezisi hakkında veriler sunmaktadır. Mektuplar bundan başka gezinin hangi amaçlarla, nasıl gerçekleştirildiği konusunda ayrıntılı bilgilerle doludur. Aynı zamanda 1908’li yılların Anadolu’sunun siyasi ve kültürel çehresini yansıtmakta, tarih ve Türklük bilimi açısından önem arz etmektedir.

Geleceğin ünlü bilim adamının henüz gençlik çağının başında olgun bir üslupla kaleme aldığı mektuplar onun kişiliğini, sahip olduğu yetenekleri gösterme açısından değerlidir ve genç bilim insanları için örnek olacak niteliktedir.
Bu çalışmada Macar Etnografya Müzesi Etnoloji Arşivi’nde bulunan Németh’in mektupları ilk defa ortaya konarak Küçük Asya gezisi ve Türkoloji açısından önemi değerlendirilmiştir.

Published: December 2021

Background: Managing principles for traumatized patients have continued to evolve with advances in technology. Hemorrhage remains the leading cause of morbidity and mortality in trauma, pre-hospital management by well-trained and well-equipped medical teams at the scene as well as in hospitals have continued to improve treatment outcomes.
Although new treatment options continue to be evidence, as well as the implementation of concepts related to the optimal time for the operation.
Although the preliminary assessment was performed using the Injury Significance Score (ISS) as an assessment and prognostic element to determine the timing of the intervention
The current consensus argues that unnecessary delays in fracture care should be avoided while respecting the complex physiology of certain groups of patients who may remain at increased risk for complications.
Using innovative techniques and understanding concepts such as the anatomy of traumatic injuries, the optimal approach to the polytrauma patient continues to evolve day by day.

This research demonstrated the important contribution of mining to the welfare of communities, emphasizing its disproportionate contribution in terms of taxes and other payments to the state. Taking into account that the state, through the public treasury, is in charge of administering, disposing and distributing. At the same time, the execution of expenses is done inefficiently and wasted by the capacity of the sector's institutions, so a deep evaluation should be made, since such contribution of the mining companies is important for the social welfare of the communities, because they are in total poverty. There is discontent in the communities that are involved in the conflicts of income distribution resulting from the extractive companies and there is inequality in the distribution of income in the provinces and districts.
In Peru, mining companies have been sources of wealth and rational enrichment where the population is involved, so mining companies have become involved in the environment contamination in the different departments. Peru is rich in minerals, due to the development of mining activities in various regions, so It will only study the provinces of Ancash. Some of the districts are San Maquino is located to the east of the Mosna river, province of Huari. To the north is the Carash River. The town of San Marcos is right where the Carash flows into the Mosna. The Carash basin, where there are several communities including Ango Raju and Carhuayoc, is therefore directly linked to the mining activities of Antamina associated with the arrival of the mining canon fraction of income tax paid by Antamina that suddenly and dramatically increased the municipal coffers so that the Municipality of San Marcos and provinces and other districts there are no improvements in roads, education and sanitation.

A FORMAÇÃO CONTINUADA EM EDUCAÇÃO FÍSICA NA RMEPEL A PARTIR DA PERSPECTIVA DOCENTE
Authors: Bremm de Oliveira Ivan , Felipe Ernst Frizzo Giovanni 
Published: December 2021

A pesquisa teve por objetivo analisar o processo de formação continuada em Educação Física (EF) na Rede Municipal de Ensino de Pelotas-RS (RMEPel) a partir da perspectiva de docentes com diferentes períodos de experiência profissional. Adotamos uma abordagem qualitativa, descritiva de estudo de caso. Os participantes do estudo foram quatro docentes de EF com 1, 13, 21 e 31 anos de atuação docente. Para a coleta das informações foram feitas entrevistas semiestruturadas e sua interpretação seguida pela análise de conteúdo. Os resultados apontaram que a busca por atualização e embasamento para o trabalho pedagógico, além de preenchimento de lacunas da formação inicial e melhoria na carreira foram os motivos que levaram os docentes à realização de formação continuada no percurso da carreira. Porém, o processo de formação continuada da RMEPel se caracterizou ao longo do tempo de forma esporádica, baseada em cursos de curta duração, predominantemente instrumental e esportivista, desconsiderando outras dimensões, como a política e a social, que também são pertinentes à EF, não promovendo a necessária reflexão/ação/transformação do trabalho pedagógico e do exercício da profissão docente. Destacamos ainda o não cumprimento da legislação vigente em relação ao piso nacional do magistério e de artigos referentes à formação continuada. Evidencia-se então a necessidade de modelos alternativos de formação continuada na área de EF.
