Heat Flux Controls by In Situ Laser Treatment for Thermal Spraying
Authors: Danlos Y. , Costil S. , Deng S. , Liao H.
Published: December 2022

In this study, Ni-Al powder is plasma sprayed on various substrates prepared by in-situ laser ablation and preheating. Surface topography and splat shape are examined in order to assess how laser induced heat flux affects surface modifications and variations in splat shape. The causes of laser induced surface modifications are identified for Al, Ti, and stainless steel substrates and it is shown that laser preheating improves surface absorptivity, which effectively subjects more defects to the effects of the laser.
Chemical Vapor Deposition and Atomic Layer Deposition of Coatings for Mechanical Applications
Authors: Doll G.L. , Scharf T.W.
Published: December 2022

This paper provides an overview of chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes and the advantages they offer physical vapor deposition for the application of friction and wear coatings for micromechanical assemblies and components. It explains how hard and solid lubricant phases can be applied by these non-line-of-sight deposition methods, achieving nanoscale conformality and coating uniformity on buried surfaces and interfaces. It also discusses inherent disadvantages and explains how plasma excitation can be incorporated in either process to overcome material limitations.
Polymer Thermal Spraying: A Novel Coating Process
Authors: Ivosevic M. , Coguill S.L. , Galbraith S.L.
Published: December 2022

A new coating process called polymer thermal spraying (PTS) was recently developed to accommodate the deposition of heat sensitive polymeric materials over a broad range of substrates. The novel process uses an electro-resistive element to heat the main process gas, which could be air, any pure gas, or gas mixture. This paper describes the process and presents three case studies in which it is used to produce blast mitigation coatings for civil structures, super-hydrophobic coatings for corrosion protection, and flame resistant polyimide syntactic foams for thermal insulation.
HVOF and HVSFS Coatings for Reduction of Wear and Friction in Cylinder Liners
Authors: Rauch J. , Manzat A. , Killinger A. , Gadow R.
Published: December 2022

This study compares the tribological performance of HVOF and HVSFS coatings applied to gray cast iron and aluminum cylinder liners. Five different materials, including Fe alloy, FeCrMo, CrC-NiCr, NiCrBSi, and WC-Co, were sprayed using a conventional HVOF torch operated by a six-axis robot while the liners were manipulated by means of a rotary table. A similar setup was used to spray TiO2-TiC coatings, but the gun was modified for nano-sized particles in a suspension fed axially into the combustion chamber. Coating microstructures were examined using optical and SEM imaging and friction and wear properties were determined through oscillating friction wear tests. The results obtained are compared to state-of-the-art cylinder liners.

Authors: Shinozawa A. , Eguchi K. , Kambara M. , Yoshida T.
Published: December 2022

In this study, a variety of yttria-stabilized zirconia (YSZ) coatings have been obtained by plasma spray physical vapor deposition with fine powders at high power. The coating structures were found to change significantly with powder feed rate, but less with substrate temperature and rotation speed. Porous YSZ coatings with a feather-like structure and low thermal conductivity were deposited at rates as high as 220 μm/min. These results demonstrate the potential of plasma spray physical vapor deposition for producing thermal barrier coatings.

Authors: Choi H. , Kim K. , Kim T. , Choi H.
Published: December 2022

A low-temperature, atmospheric-pressure spraying process was recently developed that facilitates the formation of highly functional films on any type of substrate using metal or nonmetal powders. This paper describes the new process and explains how different parameters, such as spraying distance, exit gas velocity, nozzle diameter, and particle size, affect the thickness, area, and composition of copper and barium titanate films on alumina, copper clad, and wafer substrates.

Published: December 2022

In this study, fine aluminum powder was cold sprayed onto aluminum substrates, some of which were polished, some grit blasted, and some pretreated using a nano-pulsed Nd:YAG laser. In the latter case, the laser is coupled with the cold spray gun and the irradiation treatment occurs just prior to deposition. To better understand the interaction mechanisms involved with laser pretreating, coating-substrate interfaces were examined on thin-foil specimens and adhesion strength was determined by laser shock testing. The results show that substrate pretreatment with a nano-pulsed laser significantly improves the coating-substrate interface as well as coating adhesion.
Studies on the Sliding Wear Performance of Plasma Spray Ni-20Cr and Ni3Al Coatings
Authors: Kaur M. , Singh H. , Singh B. , Singh B.
Published: December 2022

In this study, two metallic powders, Ni-20Cr and Ni3Al, were plasma sprayed on stainless steel substrates in order to compare their sliding wear properties. The coatings exhibited typical splat morphology prior to wear testing. After wear testing, the coatings were again examined along with an uncoated substrate. It was concluded that although either coating can effectively reduce the wear rate of 309 stainless steel, the Ni3Al coating is a better choice.
Wear Behavior of Plasma Spayed Al-Si/TiB2/h-BN Composite Coating
Authors: Ozdemir I. , Tsunekawa Y. , Tekmen C. , Grund T. , Wielage B.
Published: December 2022

In this work, mechanically alloyed Al–12Si/TiB2/h-BN composite powder was deposited onto an aluminum substrate by atmospheric plasma spraying. The results revealed that the mechanical alloying (MA) process has a significant effect on composite powder morphology and in-situ reaction intensity between the selective powders during plasma spraying. In addition, hexagonal boron nitride (h-BN) powder incorporated as a solid lubricant, which has excellent lubricating properties, decomposed into B and N and formed a solid solution after a long period of milling. More specifically, during plasma spraying a large amount of h-BN reacted with Al to form AlN. Unlubricated ball-on-disk testing ring was used to examine the anti wear performance of the coatings. The worn surfaces were examined using scanning electron and energy dispersive spectroscopy to elucidate the wear mechanisms operating at the sliding interface.

Objective of the Review: on the basis of domestic and foreign conciliation documents and the results of our own research, to present up-to- date information about a dangerous complication of bronchopulmonary dysplasia - pulmonary hypertension. Key Points: pulmonary hypertension is a common complication of bronchopulmonary dysplasia, which has antenatal, perinatal and postnatal risk factors. The presence of risk factors, respiratory failure, bronchial obstruction in a child with bronchopulmonary dysplasia is the basis for excluding pulmonary hypertension by echocardiography, which allows to detect an increase in pressure in the pulmonary artery, indirect signs of pulmonary hypertension. An obligatory method of treatment of pulmonary hypertension in children with bronchopulmonary dysplasia is oxygen therapy. With insufficient effectiveness of oxygen therapy, treatment is sequentially carried out with sildenafil, bosentan, and nitric oxide. Conclusion: Since the clinical manifestations of pulmonary hypertension in children with bronchopulmonary dysplasia are indistinguishable from the symptoms of the underlying lung disease, timely screening of this complication and the appointment of therapy are necessary. Keywords: bronchopulmonary dysplasia, pulmonary hypertension, chronic pulmonary hypertension in infants, diagnosis, therapy.

This paper presents the past and present occurrence of Mantis religiosa in Poland and discusses range changes of this species during the last 100 years (1923–2021), based on 2664 records, 2029 of these unpublished. Up to 1994, the species was restricted to a relatively small area in the south-eastern part of Poland (3.3% of the country's area). During 27 years (1995–2021), M. religiosa spread from there to the north, west and south, increasing its range more than 20 times, to 77% of Poland’s area. At present, only north-western part of the country and central part of mountainous belt in the south are not occupied or sparsely occupied by this species. The average annual increase in European mantis range in Poland in the years 2013–2021 was eight times faster than during the earlier period (1995–2012).

Authors:   Russian Scientific Research Institute of Land Improvement Problems, Shevchenko A. V.
Published: December 2022

Purpose: development of a layout and design solution for the Kochetovsky fish passage and spawning channel, traced along the Barsovka riverbed. Materials and methods. The basis for the channel layout and design solution development was the data of hydrological studies and plans for topographic survey of the area, recommendations for fish breeding and biological substantiation of the channel, materials for the development of projects and the use of fish passage and spawning channels as part of the Nizhne-Don waterworks. The generally accepted methods were used at collecting and processing the initial information, and the approaches and methods for the search design of waterworks were used when developing structures. Results and discussion. Taking into account the natural conditions of the floodplain section of the Don river near waterworks and the presence of a specially protected area here, the option of tracing the main part of the canal tract along the Barsovka riverbed, which was the Don river watercourse before the construction of the Kochetovsky waterworks was considered. The conditions for channel creation and operation are characterized by the magnitude of the calculated difference in water levels and are determined by the need to create conditions for the anadromous, semi-anadromous and other aquatic fish movement from the downstream of the hydroelectric complex to the upstream and (or) their spawning in the channel tract. As a result of research and development, it was proposed to construct a channel with a length of 8540 m, a trapezoidal cross section, with an estimated water flow depth of 2.6 m, a bottom width of 30 m and a 1:3 slope. With an average slope of the channel bottom of 0.000338 with a stone-gravel-pebble coating of its channel and an estimated flow rate of 90 cubic m/s, the average velocities in the channel tract are 0.95 ± 0.5 m/s. The channel includes an inlet and outlet heads, a tract with fish recreation areas and a spawning substrate for litho- and phytophilic fish. Conclusion. A layout and design solution for a fish passage and spawning channel which is proposed for arrangement at the Kochetovsky waterworks on the Don river has been developed.

Purpose: to analyze the results of monitoring some indicators of soil fertility in Central irrigated zone of Rostov region. Materials and methods. The data of the state monitoring of Rostov region lands, the Federal State Statistics Service data, the results of our research conducted in Bagaevsky district Rostov region were used. Results. An analysis of changes in humus content in Central irrigated zone soils revealed a trend towards a decrease in its value to 2.95 % by 2000. Further, since 2000, a slight increase in the humus content has been noted. During the period from 2015 to 2021, there is a decrease in the humus content in two of the three surveyed areas. In Volgodonsk region, the humus content in 2015 was 2.4 %, which did not change for the survey period in 2021, and was the minimum indicator for the areas in which the work was carried out. The phosphorus content in Central irrigated zone soils in the areas where the survey was carried out, is low, and potassium is very high. In 2021, in comparison with 2015, a decrease in the soil main microelements content was also noted, and there was a slight decrease in the reaction of soil medium from 7.8 to 7.7 and from 7.66 to 7.61. An assessment of the agro-productive capacity of soils was carried out on the example of Bagaevsky district Rostov region. Conclusions. The analysis of the soil fertility monitoring in Central irrigated zone revealed a negative trend towards a decrease in the main indicators. Such changes in the fertility main indicators have a significant impact on the ecological situation developed on these soils. The issue of increasing fertility should be solved taking into account the resistance of soils to degradation, this issue should be worked out most carefully on irrigated lands.

Lay Definitions of Successful Ageing and Contributing Factors among Croatian Older Adults
Authors: Tucak Junaković Ivana , Ambrosi-Randić Neala
Published: December 2022

Lay concepts of successful ageing have attracted the attention of researchers over the past 15 years. However, little is known about how older people in Southeastern European countries understand successful ageing and the factors associated with it. Therefore, the aim of this qualitative study conducted in Croatia, a Southeastern European country, was to explore Croatian older people’s definitions of successful ageing and the contributing factors. Interviews were conducted with 95 community-dwelling older men (49.5% of the sample) and women (50.5%) aged 65 to 90 years. Participants answered questions about definitions and contributing factors/determinants of successful ageing. Responses were subjected to thematic analysis. Results showed that participants gave similar responses to questions about the components and determinants of successful ageing. The most frequently mentioned components of successful ageing were the physical/physiological (with subthemes of general health, healthy habits, and physical mobility), the psychological component (with subthemes of good life, subjective well-being, and psychological resources, etc.), and the engagement and activity component. Among factors that contribute to successful ageing, social and physical were mentioned most frequently, followed by psychological, financial factors, and engagement/activity. Longevity and good genes were rarely cited as factors associated with successful ageing. Besides, Croatian older people have not mentioned spirituality or religiosity as important components or determinants of successful ageing. The results of our study are mostly consistent with the findings of previous research on successful ageing in predominantly Western cultures. They show the great heterogeneity of lay conceptions, which are much broader and more complex compared to researchers’ models of successful ageing.
The Association between Subjective Well-Being and Risky Behaviours in University Students
Authors: F. Alves Regina
Published: December 2022

This study examined the mediating role of social factors (friends’ substance use, living with family and having a romantic partner) in the relationship between subjective well-being and health-risk behaviours. This is a cross-sectional study of 840 Portuguese university students that used a probabilistic sampling technique. The data were gathered using a paper-and-pencil questionnaire which included three main areas: subjective well-being, health behaviours and social factors. Structural equations were used for modelling and analysis in order to test the mediating effect of the social factors in the correlation between subjective well-being and risky behaviours. Structural equation modelling showed that behaviours that put one’s health at risk were directly and positively related to having friends who use psychoactive substances and negatively with the following variables: having a romantic partner and living with family. The mediation analysis showed that social factors significantly mediated the correlation between subjective well-being and health-related risk behaviours. This study highlights the importance of taking into account the importance of social networks when designing educational interventions to improve student health in higher education settings.
Миграции степных племен в Европу в конце IV–III тыс. до н.э. и фор-мирование культур шнуровой керамики
Authors:   Институт истории и археологии УрО РАН, Григорьев Станислав
Published: December 2022

Существует две основные гипотезы о локализации индоевропейской прародины. Пер-вая связывает распространение индоевропейцев с миграциями курганных культур Понто-Каспийских степей, в первую очередь, ямной. Поэтому она получила название «курганная». Вторая предполагает локализацию индоевропейской прародины на Ближнем Востоке. В соответствии с курганной гипоте-зой, ямная миграция в начале РБВ привела к формированию культур шнуровой керамики от Рейна до Волги, что вызвало распространение и формирование современных европейских диалектов. В дейст-вительности, оснований для предположений о формировании шнуровых культур на ямной основе нет. Они формировались отчасти на основе европейских неолитических культур, отчасти на основе импуль-сов из степной зоны в пред-ямное время, что подтверждается как характером материальной культуры, так и палеогенетическими исследованиями. Эти миграции начались в раннем энеолите, но были весьма немногочисленны и ограничены Нижним Подунавьем. Они не оказали заметного влияния на культу-рогенез даже на Северных Балканах. В среднем энеолите этот процесс прекращается и возобновляется лишь в финальном энеолите, в последней трети IV тыс. до н.э. Основным его актором выступала группа Животиловка-Волчанское Северного Причерноморья. Ее проникновение в Балкано-Карпатский регион способствовало установлению прочных связей со степной зоной Причерноморья и последующим глу-боким контактам, сохранившимся в ямное время. Ямные проникновения в юго-восточную Европу (се-веро-восточные Балканы, Паннония, отчасти Волынь), действительно, имели место, и по времени они совпадают с формированием культур шнуровой керамики. Однако, в основе последних были местные субстраты и потомки степных энеолитических племен.

Статья посвящена публикации кованого наконечника копья, случайно обнаруженного в селе Миловка Уфимского района Башкортостана. По морфологическим показателям он полностью соответствует другим экземплярам разряда КД-2 и наиболее близок наконечнику из Турбинского мо-гильника. Приведена графическая реконструкция этапов его изготовления, которая опирается на метал-лографический анализ кованых наконечников разряда КД-4, проведенного А.Д. Дегтяревой, и литейные формы с негативами орудий, формовавшихся кузнечной ковкой после отливки. Все наконечники КД-2 изготовлены из мышьяковой бронзы, а небольшое количество цинка (0,32 %) в миловском экземпляре указывает на связь его металла с медно-цинковыми месторождениями Южного Зауралья. В системе ра-диоуглеродной хронологии наконечники копий разряда КД-2 могут быть отнесены к древностями XX в. до н.э. с возможным удревнением нижней границы их бытования до конца XXI в. до н.э. Сравнительный анализ материалов рубежа эпох средней и поздней бронзы Волго-Уралья позволяет синхронизировать часть сейминско-турбинских, не самые поздние средневолжские и развитого этапа волго-уральские аба-шевские и ранние синташтинские памятники, а их бытование отнести ко времени, предшествующему и синхронному началу «колесничего горизонта» эпохи поздней бронзы (XX–XVII вв. до н.э.).
Миграции в Сургутском Приобье в конце бронзового – начале железного веков
Authors:   Уральский государственный  педагогический университет, Чемякин Юрий
Published: December 2022

Древние миграции далеко не всегда оставляют в археологических источниках явные следы. Но в ряде случаев артефакты позволяют однозначно интерпретировать их как свидетельства передвижения населения. В Сургутском Приобье накануне и в течение раннего железного века зафик-сированы две бесспорные крупные миграции, причем в противоположных направлениях. В конце брон-зового века сюда с севера проникают коллективы атлымской культуры. В районе Белогорского материка, где сформировалась эта культура, известно около 20 ее памятников. Столько же открыто в бассейне Конды и в низовьях Иртыша. В Сургутском Приобье выявлено не менее 45 атлымских поселений и местонахождений. Они содержат оригинальную керамику, отличающуюся от местной не только фор-мой, орнаментацией, но и технологией. Взаимодействие носителей атлымской культуры с населением аборигенной барсовской приводит к формированию белоярской культуры. Она существовала в первой половине раннего железного века и представлена более чем 100 памятниками (селища, укрепленные по-селения, местонахождения). В этот же период в регион с юга приходит население – носители калинкин-ской культуры. Ее основные характеристики не имеют корней в местных культурах. Это оригинальные планировка поселений, керамика, а также знакомство с коневодством. Район, где она сформировалась, до сих пор неизвестен. Предположительно, это может быть южная тайга Васюганья. В Сургутском При-обье открыто около 60 поселений, городищ и местонахождений калинкинской культуры. В результате взаимной ассимиляции калинкинских групп и населения белоярской культуры складывается сургут-ский вариант кулайской культуры.
Этнокультурная ситуация на северо-восточной периферии сакской куль-туры Притяньшанья в IV–III вв. до н.э.
Authors:   Киргизский национальный  университет им. Ж. Баласагына, Иванов Сергей
Published: December 2022

Статья посвящена вопросам этнокультурных контактов населения сакской культуры Притяньшанья на северо-восточной периферии территории ее распространения. В первой половине IV в. до н.э. начинается экспансия пазырыкского политического объединения на юг – в Восточный Ка-захстан, северный Синьцзян и Монгольский Алтай. Это приводит к военному столкновению с саками Притяньшанья, которые утрачивают влияние на племена среднего течения Иртыша и связи с родствен-ной каменской культурой Лесостепного Алтая. Миграция пазырыкцев приводит к формированию ги-бридной кула-жургинской культуры Восточного Казахстана, носители которой продвигаются в северо-восточные районы политического объединения саков Притяньшанья, как, собственно, и сами племена пазырыкского культурного круга. Военное противостояние с ними, как и военные конфликты с элли-нистическими государствами на юго-западе, ослабляют данное объединение. Итогом становится его разгром в результате миграции юэчжей около 165 г. до н.э., что приводит к выдавливанию значительной части сакских племен Притяньшанья в южные районы Средней Азии.

В статье рассматриваются миграционные процессы, происходившие на территории Урало-Поволжского региона в I тыс. н.э., в их археологическом проявлении. Используя метод историко-географической характеристики археологических культур региона в рассматриваемый период, автор определяет типы миграций (согласно типологии, разработанной в отечественной и зарубежной архео-логии), их масштабы и результаты в формировании этнической карты Урало-Поволжья. Полученные ре-зультаты позволяют сделать вывод о том, что в конце эпохи раннего железа и в первые века I тыс. н.э. в регионе имели место вторжения воинских дружин поздних сарматов, вследствие чего происходят терри-ториальные подвижки местных пьяноборских, гляденовских и караабызских племен. В эпоху Великого переселения народов позднесарматская инвазия приобретает характер миграции-вторжения. В резуль-тате этого в регионе формируются три этнокультурных ареала: именьковско-турбаслинский (позднесар-матский), финно-пермский (азелинская и мазунинская/бахмутинская культуры) в Южном Предуралье, неволинская культура в её ранней (бродовской) стадии в Среднем Прикамье и ломоватовская (харинская стадия) – в Верхнем Прикамье. Во второй половине I тыс. н.э. Урало-Поволжский регион становится этнокультурным ареалом (ЭКА) древних угров, представленных памятниками кушнаренковской, кара-якуповской, неволинской, ломоватовской и чепецкой культур, которые морфологически (и генетически) были связаны с бакальской культурой Среднего Зауралья. На этом основании в современной археологии региона господствует концепция об иммиграции – ползучем вторжении зауральско-западносибирских угров в Предуралье и их продвижении далее в Среднее Поволжье (земля Хетумогер/Дентумогер древ-них мадьяр). В самом конце I тыс. н.э. угорский период в истории населения региона завершается, что выражается в резком сокращении ареала угорских памятников (петрогромско-мрясимовского типа) в Предуралье. Представляется наиболее вероятным, что произошло это вследствие тюркской (огузо-пе-ченежской) миграции-вторжения в степи Урало-Поволжья на рубеже IX–X вв.

Sestrinski vjestnik
Authors: Franković Sanda , Čuljak Martina
Published: December 2022

Osnutak Škole za sestre pomoćnice u Zagrebu 1921. označio je početak profesionalizacije sestrinstva u Hrvatskoj. Sestre pomoćnice ubrzo osnivaju strukovno udruženje i pokreću stručno glasilo. U prosincu 1932. izdaju prvi časopis na području tadašnje države, Vjesnik Sekcije za Savsku banovinu Jugoslavenskoga društva diplomiranih sestara pomoćnica. Izašao je samo jedan broj nakon čega u siječnju 1933. dolazi do promjene naziva časopisa u Sestrinsku riječ, koja izlazi do 1940. Nakon stanke od dvije godine, 1942. počinje se izdavati Sestrinski vjestnik (dalje Sestrinski vjesnik) koji izlazi zaključno s prvim brojem časopisa 1945. Prilozi u časopisu analizirani su s obzirom na stalne i povremene rubrike kojima su pripadali ili s obzirom na teme koje su obrađivali. Prilozi su objavljivani u sedam stalnih rubrika i jednu povremenu. Stalne rubrike bile su: Sestre nam pišu, Iz družtva, Iz uredništva, Promjene u službi kod sestara Glavnog ravnateljstva za zdravstvo, Mi čitamo, Zrnca i Sa kućnih posjeta, a povremena rubrika je Što drugi pišu. Ostali prilozi grupirani su tematski, prema sadržaju koji obrađuju, na sljedeće teme: položaj sestara u državi, sestrinsko zvanje, sestra kao promicatelj socijalne medicine i rad u institucijama, rad sestara na selu, zaštita žene (majke) i djeteta, bolesti i ozljede te priče iz sestrinske prakse. Autori većine priloga su sestre, a priloge o bolestima i ozljedama pišu liječnici. Sestrinski vjesnik imao je nekoliko funkcija: informativnu, edukativnu i promicanje profesionalne solidarnosti. Uz zapisnike Društva diplomiranih sestara pomoćnica Nezavisne Države Hrvatske od 1940. do 1945., časopis je iznimno vrijedna građa za analizu rada sestara pomoćnica toga vremena.
John Keats as a Medical Student
Authors: Casaccia Jessica , Borghi Luca
Published: December 2022

John Keats (1795-1821), besides being the famous English poet, was a student of medicine at the United Hospitals in London. On the occasion of the bicentenary of his death, we would like to pay tribute to this versatile figure with a photographic itinerary of his medical life. This article, in connection with the project “Himetop – The History of Medicine Topographical Database”, retraces objects and places where the poet lived, studied, worked, and prematurely died, showing the importance of material culture. The photographic journey starts in London with the birthplace of the poet and continues through the places of his infancy and youth, the school in Enfield, the lodgings at 8 St. Thomas Street, the United Hospitals, etc. After giving up medicine to devote to poetry, the itinerary proceeds in the Hampstead and, as the ultimate destination, in Rome, where John Keats spent his last months of life due to tuberculosis. To conclude the path at the Protestant Cemetery in Rome, where he was buried, surrounded by grass and flowers. The material memories left by John Keats, as well as preserving his memory, take on a significant educational and inspirational role for everybody and, in particular, literary people and medical students.

EFEKTIVITAS KOMPRES CUKA TERHADAP PENURUNAN SUHU TUBUH PADA BALITA PASCA IMMUNISASI DASAR DI PUSKESMAS CEMPAKA KOTA BANJARBARU
Authors: Mariana Evi Risa , Suroto Suroto
Published: December 2022

Kondisi demam pada balita tidak hanya karena adanya penyakit juga dialami setalah mendapatkan immunisasi dasar. Ada dua manajemen demam yaitu farmakologi dan non farmakologi. Salah satu tindakan non farmakologi terhadap penurunan panas adalah kompres sebagai metode pemeliharaan suhu tubuh dengan menggunakan cairan atau yang dapat menimbulkan hangat atau dingin pada bagian tubuh yang memerlukan. Untuk menurunkan suhu tubuh, dikenal juga obat demam tradisional dengan cuka yang harganya sangat terjangkau dan juga efektif meredakan demam. Obat ini meredakan demam dikarenakan kandungan asam di dalamnya dapat berfungsi untuk mengeluarkan panas dari dalam tubuh. Selain itu, obat demam tradisional ini mengandung banyak mineral yang dapat memenuhi kebutuhan mineral tubuh akibat demam.

Jenis penelitian ini adalah adalah eksperimen semu (quasi experimental) dengan rancangan pre test – post test control group design. Tujuan penelitian ini adalah untuk menganalisis suhu tubuh balita pasca immunisasi setelah diberikan kompres cuka dan tanpa cuka serta menganalisis efektivitas kompres cuka sebagai bahan kompres dengan cara membandingkan suhu tubuh balita pasca immunisasi dengan suhu tubuh normal. Populasi dalam penelitian ini adalah seluruh balita yang mengalami demam pasca immunisasi dasar di Puskesmas Cempaka Kota Banjarbaru. Sampel diambil secara accidental sampling dalam waktu 2 bulan, yang dijadikan sebagai kelompok perlakuan dan kelompok kontrol. Analisis data dengan menggunakan Independent t-test dan Paired t-test dengan signifikansi α 0,05.

Hasil Penelitian menunjukkan adanya perubahan suhu tubuh antara kelompok perlakuan/intervensi (kompres cuka) dengan kelompok kontrol (tanpa kompres cuka) menggunakan uji independent sample t test  didapatkan nilai p<α=0,05 dengan tingkat kesalahan,  α= 0,05.  Jika nilai p<α=0,05 maka Ha diterima, berarti terdapat perbedaan yang signifikan antara  suhu tubuh pada balita yang dilakukan kompres cuka dengan yang tidak memakai cuka. Kesimpulan terdapat perbedaan yang signifikan antara  suhu tubuh pada balita yang dilakukan kompres cuka dengan yang tidak memakai cuka. Saran bagi Puskesmas Cempaka Kota Banjarbaru khususnya poliklinik immunisasi dan kader posyandu dapat memberikan alternatif kompres cuka (metoden non farmakologi) untuk menurunkan suhu tubuh balita pasca immunisasi
Axillary lymph node “bubbly” calcifications and body tattoo: A case series and proposed algorithm to minimize lymph node biopsies
Authors: Yepes Monica M. , Feliciano Yara , Net Jose , Betancur Veronica , Gomez-Fernandez Carmen , Collado-Mesa Fernando
Published: December 2022

The presence of mammographically evident hyperdense foci within axillary lymph nodes elicits concern for calcium deposits, which in turn have a wide differential diagnosis including both benign and malignant entities. Tissue sampling, most commonly by way of image-guided core needle biopsy, is needed in many cases when a definite etiology cannot be clinically established. In this case series we present history, imaging findings, and pathology results (or long term follow-up stability as biopsy surrogate) of several women with body tattoos who at mammography were noted to have a characteristic pattern of “bubbly” pseudo-calcifications within axillary lymph nodes, and absence of other mammographic, sonographic and clinical abnormalities.
Enhanced deep learning network for emotion recognition from GIF

Published: December 2022

The Graphic Interchange Format (GIF) is a bitmap picture format that has a series of perpetually repeating images or silent movies that may be viewed without the user having to click and start them. GIFs are frequently used to visually represent emotions that are expressed through body language such as gestures, movements, and facial expressions. Computing may be used to recognise thoughts and other emotions like desire, interest, sentiments, etc. by using emotional expressions or movements as face markers or properties in GIFs. The ability to predict emotions in GIFs may make it easier to express oneself on social media and convey a person’s attitude or personality. Emotion detection in GIFs may be utilised for a range of purposes, e.g., developing a recommendation system, detecting inappropriate content, sentiment identification from GIF-induced sentiment as perceived by person and creating a GIF tag generating system. This study discusses the prior contributions made towards emotion identification in GIFs and describes a method for detecting seven different emotion classes (Happy, Anger, Sad, Surprise, Disgust, Fear, and Neutral) in GIFs by combining an activity recognition network with face emotional expression. The suggested deep neural network, RNN, LSTM approach produced an F1-score of 0.89 and an accuracy of 88 percent.
THE RELATIVISTIC OBSERVER: Consequences of a Linear Expansion of Spacetime
Authors: Skidmore Frank M. , Tanik Murat M.
Published: December 2022

Communication Dynamics Theory, defined in a companion paper, offers a new approach to understanding Spacetime. In Communication Dynamics Theory, physical reality is assumed to arise from an anisotropic expansion of a one-dimensional communication network. In this paper, we perform a first approximation mathematical transformation of the theory into hyperbolic geometry. The resulting model provides a potential basis for developing insight pertaining to previously poorly understood fundamental constants of physics. As a demonstration, we define a proton, neutron, and electron, demonstrate the emergence of observable space and time, and generate heuristic estimates of Euler’s number, the fine structure constant, and π, as well as geometric descriptions of fundamental forces of nature, occurring as natural consequences of the linear dynamic expansion of Spacetime.

BACKGROUND: Customized employment (CE) is a highly relevant but underused strategy for individuals with significant disabilities. It is important to examine how CE has been utilized in state vocational rehabilitation agencies (SVRAs). OBJECTIVE: The purpose of this study is to identify SVRAs’ CE service patterns and outcomes from 2017 to 2020. METHODS: Descriptive analysis, chi-square, and t-test comprised data analysis. RESULTS: 78% of the consumers receiving CE were associated with 10 SVRAs. This sample (N = 1,779) was 57.4% male and 42.6% female and had a mean age of 31.61 years. 77% were White. The frequent services provided with CE were VR counseling and guidance, assessment, and job placement assistance. Based on the service provision pattern, the agencies were separated into Group A, using co-occurring services other than supported employment (SE), and Group B, using SE along with CE. Consumers served by Group B are more likely to have cognitive impairment, intellectual disability, and the most significant disability. Group A is associated with lower employment, higher weekly earnings, and weekly hours worked. CONCLUSION: VR agencies and providers should consider these findings to refine and improve their service delivery and policies/procedures particularly for customized employment.
