Microstructure and mechanical properties of a rotary friction welded tungsten heavy alloy
Authors: Damodaram Ramachandran , Karthik Gangaraju Manogna , Lalam Sree Vardhan
Published: March 2019

Tungsten heavy alloys (WHAs) are widely used in many aerospace and defence applications such as radiation shields, kinetic energy penetrators etc. In the current work, attempts were made to join WHA rods (8 mm in diameter) using rotary friction welding techniques. The WHA rods were prepared via conventional liquid phase sintering and had a two phase microstructure containing tungsten particles of spherical shape and surrounded by a solid solution matrix of Fe, Co and Ni. Rotary friction welding process parameters were successfully optimized and a sound weld with a narrow weld interface without any defects was obtained. The weld interface was found to be of a uniform width of around 150 μm throughout the weld interface and showed very fine fragmented tungsten particles with a refined matrix phase. Moreover, the thermomechanically affected zone (TMAZ) elongated tungsten particles were clearly seen to react normally to the compressive force direction. Further, the heat-affected zone width was so narrow that it was not detected in the current study. Microhardness at the interface showed increased hardness when compared with the base material indicating that the microstructural refinement occurred during friction welding. Tensile tests carried out at room temperature as per ASTM-E8, showed lower strength and ductility when compared with the base material (tested along the hot-working direction). The fractography of the fractured surface of the base material and weld sample confirmed that the ductile mode of fracture had occurred.

Published: March 2019

The present work deals with the three body abrasive wear behavior of sansevieria cylindrica fiber (SCF) and E-glass fiber (EGF) reinforced polyester resin (PR) composites. A dry sand rubber wheel (DSRW) test set up was used to test the three-body abrasive wear behavior of composites. Composites fabrication and testing were performed as per ASTM G65-04 standards. The composites were fabricated by varying the weight percentage (wt.-%) of SCF and EGF. The DSRW test was conducted by varying the sliding distance, 1000 m and 2000 m, and the applied load, 24 N and 36 N, at a constant speed of 200 rpm. The worn out surfaces of the composites were examined using a scanning electron microscope (SEM) and the mass loss, volume loss and the specific wear rate of the composites were determined. The wt.-% 30 SCF, wt.-% 20 EGF, wt.-% 50 PR composites revealed a better wear resistance as compared with all other combinations.

Authors: Uzay Cagri , Geren Necdet , Boztepe Mete Han , Bayramoglu Melih
Published: March 2019

Sandwich structures offer innovative alternative solutions to many weight-critical industrial fields due to their lightweight and very high flexural rigidity compared to conventional materials. A vast number of sandwich configurations can be produced from a variety of materials for use as face sheets and core as well as matrix. Although there are many sandwich structures available in the literature to obtain the desired mechanical and physical properties, the usage of very low-density core materials is very limited. In this study, carbon and glass fiber fabrics having woven plain and ±45 ° fiber orientations and industrial PVC foam core having extremely low density of 40 kg × m−3 and 48 kg × m−3 were used for manufacturing the sandwich panels. Eight different configurations were constructed by hand lay-up followed by vacuum bagging. According to ASTM C393/C393M standard, the sandwiches were subjected to three-point bending (TPB) tests. After performing the TPB tests, the composite sandwich specimens were examined under a stereomicroscope to determine failure modes. The primary failure modes under quasi-static bending loading were found to be top face sheet failures due to fiber and matrix cracks and delamination, and core shear failures due to core crushing just below the top facing and core fractures. In addition, the consistency of the test results were verified and the effects of parameters were investigated by using statistical variance (ANOVA) and regression analysis. The study provides a valuable contribution to the literature regarding sandwich structures having extremely low-density foam core materials and may contribute to the material universe by introducing strong, stiff and lightweight sandwich composites. It provides a comprehensive comparison by considering the effect of different fiber types, fabric fiber orientations and core densities.

Published: March 2019

The major difficulty faced in a machining process is predicting the failure of cutting tools and analyzing the stipulated time for tool replacement. The former and latter can be achieved through a monitoring system that surveys the effective condition. This present research work is focused on analyzing tool condition by adopting a vibration signature during the machining of a hybrid aluminum alloy composite using various coolants. The experiments were conducted employing various tools under optimum process parameters utilizing vegetable based cutting oil as a coolant. During the machining process, a vibration signature from the workpiece was acquired using an NI 6221 M series DAQ card allowing for various time domain features to be extracted. The arithmetic mean and skewness significantly increased for dull tools. Based on the extracted features, a decision making algorithm for tool condition monitoring system has been proposed. The result shows that the features extracted increased consecutively with an increase in flank wear.

Published: March 2019

No presente artigo, empenhamo-nos em analisar a realidade e as possibilidades no ensino de uma prática experimental em termometria utilizando inovação tecnológica de baixo custo, aplicada em duas turmas de ensino médio de escolas públicas da cidade de Bragança, Pará, Brasil. Apoiados em teóricos da área de ensino de física, em documentos oficiais da educação e no uso de um Arduino como aparato tecnológico inovador, buscamos elementos para fundamentar a proposta didática. Para atingir o foco da pesquisa, utilizamos as bases da abordagem qualitativa da pesquisa, na qual buscamos identificar duas dimensões, a realidade e as possibilidades, de acordo com a dialética do materialismo histórico, proposto por Cheptulin (2004). Os dados foram coletados a partir da aplicação de um questionário contendo perguntas abertas e fechadas para o relato de vivências e concepções dos alunos. Do material empírico analisado, identificamos informações sobre a reflexão da realidade vivenciada pelos alunos em aulas de física, bem como motivações para aprendizagem e perspectivas para a prática a ser aplicada em contexto real. Os dados possuem potencialidades para reaplicação da proposta, associação de teoria à prática, afirmando, portanto, o uso de recursos tecnológicos como ferramenta para dinamização das aulas de Física.
(Alguns) desafios para os Produtos Educacionais nos Mestrados Profissionais nas áreas de Ensino e Educação
Authors: Gonçalves Carmen Érica Lima de Campos , Oliveira Carolina de Souza , Maquiné Gilmara Oliveira , Mendonça Andréa Pereira
Published: March 2019

A elaboração de produtos é uma obrigatoriedade nos Mestrados Profissionais e, em particular, nos cursos da área de Ensino e Educação, é imperativo que as pesquisas realizadas resultem em um produto educacional com potencial de inserção na Educação Básica, Profissional e Ensino Superior. Para que esta inserção aconteça, é necessário superar alguns desafios (linguagem, capacidade de replicação, internacionalização, disponibilidade e acessibilidade) a fim de maximizar as oportunidades de alcance e uso dos produtos educacionais pelo público a que se destina. Neste artigo, foi conduzida uma investigação qualitativa, segundo uma estratégia exploratória sequencial, em duas fases: uma fase inicial de coleta quantitativa de dados (catalogação de produtos educacionais), seguida de uma fase de análise qualitativa dos dados coletados, segundo critérios estabelecidos na literatura e legislação sobre produtos educacionais. A investigação resultou em um conjunto de produtos educacionais, consolidados no cenário nacional e internacional, que apontam reflexões e possíveis caminhos para subsidiar o trabalho de professores, estudantes e gestores de mestrados profissionais para a ampliação do estudo sobre produtos educacionais, assim como o enfrentamento dos desafios para sua elaboração e inserção social.
Internacionalizando a Rede Federal de Educação Profissional: descobertas empíricas e análises emergentes
Authors: Schiedeck Soares de Souza Claudia
Published: March 2019

A Rede Federal de Educação Profissional, Científica e Tecnológica foi criada pela Lei 11.892/2008, contando na sua formatação atual com apenas 10 anos. Concomitante ao desafio de ofertar educação pública e gratuita em regiões do país que não possuíam acesso ao ensino superior e técnico, seus campi receberam a tarefa de operacionalizar o Programa Ciência sem Fronteiras que trouxe para o cotidiano institucional uma nova temática: a internacionalização. O presente artigo tem por objetivo analisar os dados quantitativos compilados pelo diagnóstico realizado pela Secretaria de Educação Profissional e Tecnológica do Ministério da Educação (SETEC/MEC) no ano de 2017, bem como ressaltar alguns aspectos relevantes desses indicadores frente às abordagens teóricas que contribuem com a temática da internacionalização no Brasil e no mundo. O levantamento coordenado pela SETEC ouviu os responsáveis pela internacionalização nas instituições da Rede Federal e recolheu informações sobre mobilidade acadêmica, acordos e projetos estabelecidos por elas. Pode-se, a partir dessa análise, perceber que a Rede Federal vem realizando esforços para se inserir na agenda de discussão mundial sobre internacionalização, os quais se refletem no número de alunos e servidores em mobilidade e nas parcerias estabelecidas, embora o detalhamento dos dados constantes desse documento seja necessário para que possamos entender o lugar da internacionalização no estágio de desenvolvimento institucional. Como consequência dessa breve discussão, evidenciamos a importância de a dimensão da internacionalização ser incorporada definitivamente nos Planos de Desenvolvimento Institucionais dos Institutos Federais, já que esses indicadores serão balizadores para as avaliações externas das instituições, além de serem utilizados para a manutenção de cursos de pós-graduação stricto sensu.

Paléopathologie dentaire et époque contemporaine : le cimetière des Crottes à Marseille, 1784–1905
Authors: Perrin M. , Ardagna Y. , Richier A. , Schmitt A.
Published: March 2019

En France, les périodes moderne et contemporaine constituent un champ d’étude récent en anthropologie biologique, et les référentiels ostéoarchéologiques restent peu représentés. En 2013 et 2014, la fouille du cimetière des Crottes (1784–1905) à Marseille a permis la constitution d’un corpus inédit. Il offre l’opportunité de caractériser l’état sanitaire d’une population soumise à de nombreux changements caractéristiques de la révolution industrielle. Il s’agit de renseigner les conséquences sanitaires des mutations socio-économiques du XIX e siècle, à partir de données archéologiques et par le biais de l’examen des pathologies buccodentaires. L’usure, les pertesantemortem, les caries et les hypoplasies de l’émail ont été observées sur les 229 individus dont les éléments dentaires sont préservés. Les résultats révèlent des prévalences très élevées des pertesantemortemet des caries, liées à une faible usure, dans un contexte d’importants changements alimentaires, d’un manque d’hygiène et d’un accès aux soins certainement limité. De plus, la forte fréquence des hypoplasies de l’émail dentaire suggère l’omniprésence de stress carentiels subis pendant l’enfance. Enfin, l’analyse diachronique, au travers des phases d’inhumation précisément datées, montre une augmentation progressive des caries et des hypoplasies tout au long de la période. La confrontation des données biologiques, archéologiques et historiques révèle une situation encore précaire, malgré les progrès dans le domaine médical et scientifique et les prémices des mesures hygiénistes.

Ontologia, desejo e política em Espinosa
Authors: Montans Braga Luiz Carlos
Published: March 2019

No primeiro movimento o artigo analisa, em panorama, a ontologia espinosana. Após, mostra como, do interior dos conceitos presentes na ontologia, derivam os de homem, desejo, alegria e tristeza, esperança e medo, segurança e desespero, ação e paixão. Da relação entre ontologia, homens e desejo – bem como dos demais afetos –, são extraídas, em breves considerações, algumas teses políticas de Espinosa. Levanta-se, neste movimento argumentativo, a hipótese de que as teses políticas espinosanas derivam de sua ontologia e de sua concepção de homem como desejo e variação de potência. O conceito de desejo é analisado à luz da variação de potência e do tema do direito natural, o qual, em Espinosa, se identifica a potência. Quando das breves derivações à política, algumas teses hobbesianas – relacionadas aos temas da multidão, povo, representação, direito natural, estado civil, etc. – são trazidas à argumentação para que se mostre, por contraste, o peso das inovações espinosanas.
Bildung e segunda natureza: Mcdowell leitor de Gadamer
Authors: Richter Bruna Natália
Published: March 2019

Em seu livro Mente e Mundo John McDowell pretende superar a oscilação entre duas abordagens que pretendem mediar à relação entre as mentes e o mundo, de um lado temos o mito do dado dizendo que os pensamentos precisam de uma coerção a partir do mundo exterior, e do outro lado temos o coerentismo que apresenta a ideia de que apenas uma crença pode justificar outra crença. Para defender sua abordagem e naturalizar as capacidades conceituais, situando a espontaneidade na natureza sem reduzi-la no interior do reino da lei. A natureza humana seria então uma segunda natureza que não é só formada a partir das capacidades adquiridas no nascimento, mas que são formadas também a partir da Bildung. Ao lançar mão dessas noções, McDowell traz a discussão das ideias de Han-Georg Gadamer sobre a experiência de abertura para o mundo através da linguagem. Deste modo, a intenção do presente artigo é de discutir sobre as implicações das noções de Bildung e segunda natureza na obra de McDowell buscando um maior esclarecimento a partir da influência e das interpretações de Gadamer.
Jean-Luc Nancy’s notion of singularity
Authors: Listik Yonathan
Published: March 2019

My article aims to explore Nancy's notion of sense as a key ontological concept because I believe this concept  as it appears mainly in his "Sense of the World", opens the possibility of a more profound understanding of his thesis. This will not be an attempt to draw a map or a line in Nancy's theory placing sense either as the starting point or as his central concept. Instead, it is an attempt to show that sense plays a significant role in Nancy's understanding of singularity and finitude and therefore provide an insight into Nancy’s overall theory of being. My argument analyses sense's centrality to Nancy´s discussion on touch and the vital role touch has in the articulation between his comprehension of mitsein/etre-avec and his elaboration of being as singular plural.
Limiares poéticos do pensamento político de Giorgio Agamben
Authors: Ornellas Sandro
Published: March 2019

O artigo apresenta o livro O fogo e o relato. Ensaios sobre criação, escrita, arte e livros (2018), do filósofo italiano Giorgio Agamben, discutindo alguns dos limiares poéticos do seu pensamento político. Parte-se de alguns dos debates subentendidos de Agamben com Jacques Derrida sobre linguagem e literatura, passa-se pelo ato poético como ato de resistência, define-se a potência inoperante presente em gestos de interrupção discursiva e chega-se à discussão sobre vida e obra em contexto biopolítico. Seguindo a ordem dos capítulos, mas sem pretender esgotá-los, o pressuposto do artigo é de que o italiano, que tem a poesia e a literatura geralmente vinculada a uma espécie de “primeira fase” de sua obra, também na série biopolítica nomeada Homo Sacer lançou mão da poesia e da literatura como forte estratégia de resistência e abertura de limiares ante a lógica que se desenha do poder soberano. Se, por um lado, o livro pode ser lido como formando um círculo hermenêutico, os capítulos, por outro lado, permitem ao leitor perceber as principais linhas em que filosofia, literatura, poesia e política se entrecruzam para o pensador italiano. Por isso, também, recorreu-se à relação direta de alguns argumentos expostos em O fogo e o relato tanto com noções e argumentos presentes em outros livros de Agamben, quanto pontualmente com outros interlocutores.
A escrita como autoformação e resistência: Foucault, Nietzsche e a criação de mundos e histórias
Authors: Galvão Bruno Abilio
Published: March 2019

A ficção corresponde a um estilo de escrita que sustenta a construção de narrativas capazes de arrancar o escritor de si mesmo em um sentido de, por meio do experimento da própria linguagem, constituir-se esteticamente. Quando observamos as obras de Nietzsche, percebemos que há uma pluralidade de estilos literários, compostos, frequentemente, por aforismos que demandam outro performático: a escrita hiperbólica. Por meio da escrita artística, Nietzsche cria um mundo compreendido como vontade de poder em que dá a si mesmo como personagem dentre outros tipos psicológicos. Já na filosofia de Foucault o traço marcante de suas obras é o tom histórico com o qual aborda seus temas. Porém, como o próprio afirma em algumas entrevistas, não escreve outra coisa que não sejam ficções, seleciona e organiza enunciados históricos criando diversos cenários, sujeitos e objetos de seu discurso. Este estilo presente em ambos entra em contato com o exterior provocando um reposicionamento do leitor, que é afetado promovendo, como efeito de subjetivação, um reposicionamento político de insubmissão de não querer mais ser governado dessa forma.
Planning of safe working space for the hot-line working robot ICBot
Authors: Tang Mingdong , Gu Youlin , Wang Shigang , Liang Qinghua , Wang Xiaoxi
Published: March 2019

With the popularization of intelligent substations, hot-line working robots that can replace the manual operation without shutting down the power of the corresponding equipments are increasingly widely applied in the maintenance and monitoring of substations. Robotic operation can ensure the safety of the operators and reliability of operation while improving the economic benefits of substation. However, because of the compact structure of the intelligent substations, the operating space is small. Further, as the main material of hot-line working robots is metal, which greatly changes the strength and distribution of the electric field around its working position when entering the working position and in the process of operation. In serious cases, interphases or phase to ground air breakdown occurs. Hence the working space of hot-line working robots is limited not only by the narrow space between devices in the substation but also by the electrical safety clearance of phase to phase and phase to ground. Therefore, it is necessary to find a safe working space (“SWS”) for the robot which should not be too small for the robot to accomplish the task effectively. The purpose of this paper is to provide: (i) a design reference for hot-line working robots which can not only guarantee the electrical safety distance but also minimize the effect to the electric field and (ii) a method to find the SWS of the robot in which the robot can accomplish the task effectively with the example of the hot-line working robot for isolated circuit breaker (“ICBot”). We analyze the influence of different installation positions and postures of the manipulators on the electric field in this paper and present a calculation method of the SWS of the manipulator in a very non-uniform electric field caused by the intervention of manipulators, which is significant to the research on hot-line working robots. The SWS has been tested in simulated and energized experimental system, and the experiment results show that the robot can work safely and efficiently.

U ovom radu opisana su osnovna načela i vladajuće jednadžbe za opis strujanja podzemne vode kroz porozni materijal. U svrhu dobivanja mjerodavnih vrijednosti pojedinih karakterističnih fizikalnih veličina kod strujanja podzemne vode u pjeskovitom poroznom materijalu (brzina procjeđivanja, ekvipotencijal u određenoj točki unutar prostora, hidraulički gradijenti, protok i sl.) korišten je fizikalni model GUNT HM169 koji čini sastavni dio hidrotehničkog laboratorija Građevinskog fakulteta Sveučilišta u Rijeci. U radu je opisan princip rada za navedeni fizikalni model te način pripreme samih eksperimentalnih pokusa. U tom pogledu, izrađeno je nekoliko hidrodinamičkih analiza strujanja podzemne vode u odnosu na varijabilnost potencijala gornje i donje vode, analiza strujanja ispod vertikalnog čeličnog žmurja (dijafragme) te analiza opstrujavanja podzemne vode ispod prostorno trapezno izmodelirane prirodne nasute brane. Za potrebe provođenja pokusa, nasuta brana ručno je izrađena od pleksi stakla. Svrha istraživanja kroz fizikalni model HM169 bila je dobivanje jasnije slike strujnog polja ispod pojedinih hidrotehničkih objekata i, posljedično, dobivanje simulacijskih prikaza propagacije toka podzemne vode koja je praćena žutim fluorescin traserom.

La sarcoidosis subcutánea o enfermedad de Darier-Roussy es una variante muy poco frecuente de esta enfermedad. No se conoce bien su etiología, aunque se han descrito algunos casos en pacientes con infección crónica por virus de la hepatitis C (VHC), especialmente tras recibir tratamiento con interferón. Presentamos el caso de una paciente con infección por VHC que desarrolló una sarcoidosis subcutánea pocos meses después de recibir tratamiento con interferón, rivabirina y boceprevir. A pesar de que podría tratarse de una asociación casual, convendría estudiar el posible papel del VHC y del tratamiento con interferón en la etiopatogenia de esta enfermedad

En este caso clínico, se muestra la utilidad de los sensores continuos de glucosa, con el fin de descubrir pacientes que por hemoglobina glicosilada están aparentemente bien tratados cuando la realidad es otra completamente diferente: mucha variabilidad, hipoglucemias inadvertidas. El uso de las nuevas insulinas lentas permite controlar mejor la variabilidad de muchos pacientes, al tiempo que disminuye el riesgo de hipoglucemias.
Antik Çağın Turizm Merkezi Olarak Troia
Authors: KORPE Reyhan
Published: March 2019

Günümüzde sadece
Türkiye’nin değil dünyanın da sayılı turizm merkezlerinden biri olan Troia ören
yeri her yıl binlerce yerli ve yabancı turist tarafından ziyaret edilmektedir.
Troia’nın Akdeniz dünyasında var olan binlerce antik kent içinde, görülmek için
bu kadar çok tercih edilmesinin nedeni, öncelikle Homeros’un destanlaştırdığı
Troia Savaşının geçtiği yerleri, kentin antik kalıntılarını yerinde
görebilmektir. Homeros destanlarının meşhur ettiği Troia bu şöhreti sayesinde
sadece günümüzde değil antik çağlarda da aynı derecede ilgi çekmiştir. Antik Yunan
döneminde var olan ziyaretler özellikle Roma İmparatorluğu ile birlikte tam
anlamıyla bir kültür turizmine dönüşmüştür. Romalı turistlerin kendi kurucu
atalarının kenti olarak gördükleri Troia’ya yaptıkları ziyaretler bu kentin
ekonomisinin önemli bir kaynağı olmuştur. Hıristiyanlık ile birlikte Roma’nın
kuruluş mitosuna olan ilginin azalmasıyla Troia’ya yapılan ziyaretler de
kesilmiştir. Troia, birçok doğal ve insani afetlerin yanı sıra, belki de en
önemli gelir kaynağının da tükenmesiyle çok geçmeden terk edilip harabeye
dönmüştür.
Troya (Truva) Millî Parkında Osmanlı Arkeolojisi
Authors: UYSAL Ali Osman
Published: March 2019

Troya (Truva) Millî Parkı,
antik Troas bölgesindeki  Troia ören yeri
ve çevresindeki tarihî – kültürel dokuyu korumak amacıyla 1996 yılında
kurulmuştur. Bu yörenin –Troia başta olmak üzere- prehistorik, proto-historik,
Yunan, Helenistik ve Roma dönemleri, Schliemann’ın kazılarından itibaren bilim
adamları tarafından etraflıca araştırılmıştır. Buna karşılık, Troya çevresinin
Osmanlı arkeolojisi açısından yeterince incelendiği söylenemez. Bu nedenle, makalemizde
millî park sınırları içindeki Osmanlı yerleşimleri ve maddî kültür verilerinin
irdelenmesi amaçlanmıştır.

Tarihsel arkeolojinin bir dalı
olan İslam Arkeolojisi içinde yeni bir alt disiplin olarak gelişmeye başlayan
Osmanlı arkeolojisinin önemi; Prof.Dr. Abdülcelil Temimî, Uzi Baram ve Lynda
Carroll gibi araştırmacılar tarafından vurgulanmıştı. Üç kıtaya yayılan Osmanlı
imparatorluğunun arkeolojisi –hiç kuşkusuz- çok yönlü ve çok boyutlu bir uğraş
alanıdır. Buna karşılık Troya Millî Parkıyla sınırlanmış bir alanın Osmanlı
geçmişini, ana hatlarıyla bir makale kapsamına sığdırmak mümkün görünmektedir.
Bu bölgede kalıcı olarak 14. Yüzyıl başlarında başlayan Türk iskânı; Orhan Gâzi
devrinden itibaren Osmanlı idaresi altında gelişmiştir. 16. Yüzyıldan Osmanlı  arşiv belgeleri, antik Troia harabeleri
(Hisarlık) çevresinde üç köy bulunduğunu gösterir. Bunlar Halil-ili (Halileli),
Kum Köy ve Kalafatlu (Kalafatlı) köyleridir.  Hisarlık’ın kuzeybatısında sahile yakın
konumdaki Yenişehir ise antik Sigeum’un (Sigeion /Sigée) yanı başında
-muhtemelen - 17. yüzyılda kurulmuş bir 
Hıristiyan köyüdür. 17. Yüzyılda Hisarlık’ın kuzeybatısında, Çanakkale
boğazının girişine Sultan IV. Mehmed’in annesi Valide Turhan Sultan tarafından
Kum Kale (Kal’a-i Sultâniye /Sultan Hisarı) ve Avrupa kıyısına Seddü’l-bahr
Kalesi yaptırılır. Vakfiye belgesinde, Valide Turhan Sultan’ın kale halkı için
bir câmi, mektep ve çifte hamam yaptırdığı da kayıtlıdır. Bu kalenin yanında
oluşan köy, Çanakkale savaşları sırasında harap olur ve köylüler Kum Köy’e (Yeni
Kumkale köyü) göç ederler. Bu sırada savaşta harap olan Kum Kale camisinin
kitabesi de Kum Köy’deki caminin minaresine yerleştirilir.

Millî parktaki Halileli
köyünde Osmanlı arkeolojisi açısından sadece mezar taşları dikkati çeker. Kalafatlı
köyüne 1928 yılında Bulgaristan’dan göçen Türkler yerleştirilmiştir. Köy bu
yıllarda yeniden kurulmuştur. Buna karşılık Çıplak Köy geç Osmanlı döneminde
kurulmuş olup; 19. Yüzyıl üslûbunda iki cepheli bir çeşmeye, bir konağa ve daha
ziyade 18.-19. yüzyıl mezar taşları bulunan tarihî mezarlığa sahiptir. Troia
harabeleri yakınındaki Tevfikiye köyü ise 19. yüzyılın sonlarında Balkanlardan
göçen Türkler için kurulmuştur. Millî park içinde Osmanlı dönemi açısından en
göze çarpan anıt, Yerkesiği’ndeki Cezayirli Hasan Paşa köşküdür. Kule ev
tarzındaki köşk; Hasan Paşa çiftliğinin köşesinde yer alıyordu. Çiftliğin diğer
binaları yıkılmıştır. Köşkün yakınından geçerek Beşik Sivri Tepe’nin
güneyindeki Hanım Değirmeni’ne su 
sağlayan kanalı ve değirmeni de Hasan Paşa’nın yaptırdığı kabul edilir.

kullanılmaktadır. Karma gerçeklik teknolojileri; interaktif ve arttırılmış
gerçeklikli videolar, 2D/3D görüntü ve sesli görüntü sistemleri, hologram, lazer
ışık teknolojileri, analog ve dijital oyunlar ile örneklendirilebilir. Yapılan
araştırmalar karma gerçeklik kullanılan müzelerin, klasik örneklerine nazaran
daha sık, daha uzun sürelerde ziyaret edildiği bunun yanında destinasyonlar
açısından tercih nedeni olduğunu ortaya koymaktadır. Bu çalışmanın amacı
Çanakkale ilindeki Yeni Troya Müzesinin sahip olduğu teknolojik altyapının
karma gerçeklikli görsel müze kriterlerine uygunluğunun incelenmesidir. Bu amaç
doğrultusunda, araştırmanın kavramsal bölümü için literatür
taraması gerçekleştirmenin yanında araştırma bölümü için yapılandırılmış
(denetimli) gözlem tekniği kullanılmış elde edilen veriler işlenerek karma
görsellik tekniği kullanılarak ortaya konulmuştur. Elde edilen sonuçlara göre Yeni
Troya Müzesi, sahip olduğu teknolojik altyapı ile altyapının sunum kriterleri
bakımından karma gerçeklikli görsel müze kriterlerini taşıdığı sonucuna
ulaşılmıştır.
Low-temperature precausticizing — a hopeful approach for green liquor desilication
Authors: Xia Xinxing , Wang Fang , Qin Xiaojing , Tang Tingting , Zhou Tianwen
Published: March 2019

We investigated silica removal by low-temperature precausticizing and the properties of second causticizing calcium carbonate (CCC). The results showed that about 89.3% of silica removal was achieved when 20% (the stoichiometric ratio) of causticizing quicklime was added for precausticizing at 20ºC for 60 min. After that, silica removal became slow. When no precausticizing quicklime was used to remove silica, the CCC particles had a rhombohedral crystal structure covered with amorphous material. As precausticizing quicklime was increased to 30%, the amorphous material and the crack disappeared, and the specific surface area decreased significantly. When CCC was used as filler, the Cobb value decreased significantly, and the sizing effect improved as precausticizing quicklime increased.

Microbiological characteristics of peritoneal dialysis-related peritonitis in an Asian
tertiary hospital 2011–2014
Authors: Sim Mui Hian
Published: March 2019

Background
Peritonitis is the leading cause of technique failure among peritoneal dialysis (PD) patients. The study aimed to examine the microbiological characteristics of PD-related peritonitis in a tertiary hospital in Singapore.
Methods
A retrospective, cross-sectional study was performed at Singapore General Hospital (SGH). Data of patients diagnosed with PD-related peritonitis from January 2011 to December 2014 were collected. Microbiological characteristics of PD-related peritonitis were reported using descriptive statistics.
Results
A total of 377 episodes of peritonitis occurred in 247 patients. The average peritonitis rate in the centre was 0.23 episodes per patient year. There were 118 (31.2%) Gram-positive, 98 (26.0%) Gram-negative, 58 (15.4%) polymicrobial, 16 (4.2%) fungal, 2 (0.5%) mycobacterium and 85 (22.6%) culture-negative, PD-related peritonitis episodes.
The three main Gram-positive micro-organisms isolated from peritoneal fluid cultures were Coagulase-negative Staphylococcus aureus (CoNS) (n=70, 17.6%), Streptococcus spp. (n=52, 13.1%) and Enterococcus spp. (n=28, 7.1%), while the three main Gram-negative isolates were Escherichia coli (n=50, 12.6%), Klebsiella spp. (n=46, 11.6%) and Enterobacter spp. (n=27, 6.8%). Candida parapsilosis (n=9, 1.9%) was the commonest fungus identified.
Only 33 (47.1%) CoNS strains were sensitive to cefazolin, which was used in the institution for empiric coverage of Gram-positive micro-organisms in PD-peritonitis. All Streptococcus strains were sensitive to cefazolin (n=52). The majority of Escherichia coli (n=38, 76%), Klebsiella spp. (n=37, 80.4%) and Enterobacter spp. (n=18, 66.7%) strains were sensitive to gentamicin, the empiric antibiotic used for coverage of Gram-negative micro-organisms.
Conclusions
Our findings highlight the importance of regular monitoring of micro-organisms and their antimicrobial sensitivities in determining appropriate, centre-specific empirical antibiotics.
