Authors: Tasnim Nasira , Bangash Kauser , Amin Oreekah , Batool Afshan , Javed Nosheela 
Published: March 2019

Aims: To evaluate the association of various predictive factors with the outcome of surgical repair of vesicovaginal fistula.
Methods: The retrospective analysis was conducted at Maternal and Child Health, Pakistan Institute of Medical Sciences, Islamabad, and it comprised data related to patients having undergone vesicovaginal fistula repair from January 2008 to June 2018. Statistical analysis of the record was done using SPSS 21 software.
Results: A total of 364 patients of urogenital fistula repair were reviewed, with an overall success in 318 (87.4%) cases. There were no significant differences in fistula duration (p0.4), size of fistula (p 0.34) and accessibility (p0.5) between successful and unsuccessful group. However, we found the association between the type of fistula and history of previous repair attempts with the success of fistula repair. Primary surgical repair of vesicovaginal (90.0%), vesicouterine (86%), ureteric (100%) and ureterovaginal (98%) were more successful as compared to repair with the history of 1 previous attempt (90.3%, 83.3%, 66.6% and 75% respectively). Success rate was found to further decrease with the history of more than one repair attempt of vesicovaginal (71.4%) and vesicouterine (66.5%) fistula. Further, successful fistula repair in women was also found to be significantly associated with parity less than 4 (p 0.038).
Conclusion: Despite the higher success rate of urogenital fistula repair, it’s important to refer the urogenital fistula patients timely to specialized fistula centres in order to achieve best results.

Published: March 2019

Abstract
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

Abstract
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.

Abstract
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

AbstractThe 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.

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.
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.

Authors: Majumder Md Mahabubul Islam , Ahmed Tarek , Ahmed Saleh , Khan Ashiqur Rahman , Saha Chinmoy Kumar 
Published: March 2019

Introduction: Bacterial resistance to antibiotics is one of the most challenging global health threats. Urinary tract infections (UTIs) are a common infection. Regional surveillance programs are necessary to update knowledge on antimicrobial resistance pattern where empirical antibiotic treatment is the mainstay. The aim of this follow up study is to see the changing trends in bacteriology and antibiotic resistance pattern among urological pathogens in comparison to similar study 5 years back.
Materials and Methods: We performed a prospective study in Comilla Medical College Hospital, Bangladesh during the period of July 2015- June 2016. Midstream clean-catch urine samples were collected from 658 suspected UTI patients with age more than 12 years and inoculated in MacConkey& Blood agar media for semi quantitative urine culture and sensitivity test. Antibiotic susceptibility pattern was done by Kirby-Bauer disc diffusion method following clinical laboratory science (CLS) program.
Results: Culture positive were in 198 samples among 658 inoculated samples. E. coli was isolated from 171(86%) samples which was the most predominant bacteria followed by Klebsiella and Enterococcus. UTI with E. coli was significantly increased in the year 2016 in comparison to 2011. Meropenem, imipenem, amikacin, tazobactum, gentamycin nitrofurantoin, and mecillinum found resistance against 0% to 12% of the urological pathogens. Bacteria offered high degree of resistance against commonly used antibiotics - amoxycillin, amoxiclav, cephradine and cefixime ranging 60% to 86%. Comparative study of 2016 vs 2011 shows significant increased resistance for ceftriaxone, amoxiclav and reduced resistance for nalidexic acid, mecillinum and cefuroxime.
Conclusion: E. coli infection is significantly increaseing in follow up study from 2011 to 2016 with no steady increase in resistance to all antibiotics. Imipenem, meropenem, tazobactum, amikacin and nitrofurantoin still remain more sensitive while comparative study of 2016 vs 2011 shows significant increased resistance for ceftriaxone, and amoxiclave and reduced resistance for nalidexic acid, mecillinum, cefixime and cefuroxime.

Scar Endometriosis: Experience of a Surgeon
Authors: Narmeen Tamanna , Pervez MM Masud 
Published: March 2019

Introduction: Cesarean section is a common obstetric surgery worldwide. As incision wound in such a surgery is exposed abundantly to endometrial tissue, incision scar endometriosis can occur. This study reports a surgeon’s experience in managing such an uncommon entity. The aim of this study was to identify risk factors for developing SCE and show the clinical spectrum of presentation. This study also shows our experience in surgical management of surgical scar endometriosis. Extra pelvic endometriosis is defined as the presence and growth of functional endometrial tissue outside the pelvis. Cesarean scar endometriosis (CSE) is a rare form of extra pelvic endometriosis that is usually confused with other surgical problems leading to delay in diagnosis.
Materials and Methods: We reviewed the case records of patients who were diagnosed as CSE in the surgery department of BIRDEM GENERAL HOSPITAL-2 from September 2013 till September 2018.
Results: We found 8 patients of scar endometriosis in 5 years making it one of the rare conditions. The age of the patients range 23–39 years and interval from symptoms to treatment varied from 16 months to 64 months. Five patients had presented to surgery department and 3 were referred from obstetric department. Cyclic pain and swelling in scar area were the most common presenting symptoms. All patients underwent excision of the mass with no recurrence of symptoms at a follow up ranging from 9 to 60 months.
Conclusion: Increasing awareness of this condition among doctors can help in early diagnosis and treatment with gratifying results. Precaution during obstetrical surgery to avoid undue contamination of the wound can reduce incidence of scar endometriosis.

Projetos em disputa: políticas públicas contraditórias no âmbito da Educação Profissional no Brasil
Authors: Rocha Paulo César da Silva , Jucá Sandro César Silveira , Silva Solonildo Almeida da 
Published: March 2019

Este artigo tem como objetivo fazer um breve resgate histórico de algumas políticas públicas de educação profissional no Brasil, revelando suas contradições. Parte-se das políticas educacionais dos anos de 1990 que estabeleceram a separação obrigatória entre o ensino médio e educação profissional, intensificado o caráter instrumental no campo da educação profissional. Nesta perspectiva educacional, percebe-se um processo de inclusão excludente, visto a sua desqualificação, que inclui no mercado de trabalho mas exclui as possibilidades que o sujeito tem de adquirir uma educação onilateral e politécnica. Na realização desta pesquisa, utilizou-se a pesquisa bibliográfica, reunindo, analisando numa perspectiva exploratória, buscando levantar informações acerca da temática dos projetos que figuraram na história do Brasil acerca da Educação Profissional.. Desta forma, acontece uma precarização do trabalho que se legitima a partir dessa continuidade de propostas precárias de Educação Profissional. Essa precarização que assola esta modalidade, propicia uma formação fragmentária, simplista e tecnicista, proporcionando uma educação unilateral em detrimento de uma formação onilateral. Enquanto a formação omnilateral possibilita uma formação que abarca todas as dimensões do indivíduo de forma ampla, em todas as suas capacidades físicas e intelectuais, a formação unilateral fragmenta o indivíduo de forma que ele apenas seja um sujeito especializado em trabalhos manuais e favorecer o lucro destinado ao modo de produção capitalista.

<p>This paper evaluates the new long-term financing strategy adopted by the 2nd Dilma Rousseff’ government, from both a theoretical perspective and an analysis of some specificity of the financing process in Brazil. The article concludes that while high interest rates - the real ‘blemish’ of the Brazilian economy - and a deformed public debt structure predominate, we cannot expect major changes in the credit market in Brazil. </p>
