Authors: Kota Sreedhar Rao , Gundala Abhilash , Sirikonda Srikanth , Metta Jayachandra Reddy , Jinde Mayur Kumar
Published: May 2019

Laparoscopic cholecystectomy is one of the commonest surgical procedures carried out in the world today. Occasionally, few undiagnosed situs inversus patients present with calculous cholecystitis. One such case is being discussed here on how the diagnosis was made and focuses on the technical approach to the operation along with review of literature. A 52 year old female presented to our department with right hypochondrial pain which was diagnosed as choledocholithiasis and calculous cholecystitis with situs inversus totalis following clinical and radiological evaluation. Patient underwent ERCP and CBD, PD stenting, following which laparoscopic cholecystectomy was performed and the patient made uneventful recovery. Situs inversus with calculous cholecystitis is a rare entity. The surgeon must appreciate that care should be taken to set up the operating theatre in the mirror image of the normal set up for cholecystectomy. Surgerons must also modify their technique to adapt mirror image anatomy.

Authors: Das Deepak Kumar , Patra Rajat Kumar , Mishra Subhrajit , Panigrahi Sudhir Kumar
Published: May 2019

Appendicular pathology is a very common entity and appendicular perforation can present in various forms ranging from right lower abdominal pain, fever and anorexia to frank peritonitis with endotoxaemic shock. We present a 18 year female with fever, anorexia and a large upper and mid abdominal swelling of 2 weeks duration which after admission was treated with intravenous fluids, antibiotics, analgesics and antiemetics. Her CECT abdomen and pelvis revealed a huge fluid containing cystic lesion with a perforated appendix tip and intraluminal faecolith and calculi.  She underwent USG guided 10F pigtail catheter drainage of the walled off peritoneal collection on 3rd day of admission. About 700 ml of serous fluid with minimal flecks was drained within 2 hours and another 860 ml over next 3 days. The pigtail drain was removed on day 7 and she was discharged on day 9, with USG abdomen confirmation of complete disappearance of the abdominal collection. Ultrasound guided percutaneous catheter drainage of the appendicular abscess with IV antibiotics cures the patient in selected case scenario.

Materials and Methods: This study was carried out in Iran using 183 samples from the Besat and Alzahra hospitals in 2017. Antibiotic susceptibility tests were performed by Kirby-Bauer disc diffusion. The modified Hodge test (MHT) was used to investigate the presence of carbapenemase. The
Expression of Recombinant Factor IX Using the Transient Gene Expression Technique
Authors: Vatandoost Jafar , Azimifar Mohammad Amin
Published: May 2019

Background: Pilot and large-scale production of recombinant proteins require the presence of stable clones, but the process of selecting stable clones is time consuming. Moreover, continuous clone culturing in large-scale production may cause loss of incoming plasmid and recombinant genes. Considering the advancements in Transient Gene Expression (TGE) technology, the large-scale expression of factor IX (FIX) was investigated in HEK cells by the TGE technique. Materials and Methods: HEK cells were seeded in a cell factory, and then transfected by pcDNA-hFIX plasmid using calcium phosphate co-precipitation method. Stable HEKhFIX cells were also seeded in a cell factory, separately. After adding vitamin K, recombinant FIX was quantified in conditioned media using an ELISA. Moreover, its functional activity was assayed using an aPTT test. Results: The results showed that the expression and activity of FIX by TGE technology was, respectively, 1.6 and 1.5 times higher than that obtained through stable HEK-FIX cells. Since calculating the specific activity revealed that for all time periods it is 0.2 mU/ng, so the increase in activity is due to the increase in the amount of FIX. Conclusions: HEK cells with higher transfectability seemed to be an appropriate alternative for transient expression for large-scale protein production. Furthermore, if rapid expression of recombinant proteins is intended, TGE can replace costly and lowyield methods.
Follow the yellow brick road: The passeur, the gatekeeper and the young migrant film-maker
Authors: Donald Stephanie Hemelryk
Published: May 2019

In the first part of this article, the author reflects on her experience of making filmmaking workshops with young people in Australia, China and the UK an integral component of a research project on the representation of child migrants and refugees in world cinema. She then sets her
approach to these workshops in the context of Alain Bergala's ideas about film education, of which she had initially been unaware. In discussing a couple of further workshops that she ran in the UK and Australia as part of the 'Cinéma, cent ans de jeunesse' programme, she focuses particularly
on the benign or obstructive role of institutional gatekeepers, who act as intermediaries or agents determining the terms of access to children and young people for film educators, researchers and practitioners. The legal, protective and ethical dimensions of the relationship between
educator, gatekeeper and participating students are discussed. The article cites cases in which the interaction worked well, and others in which it proved problematic. The functions, responsibilities and potential drawbacks of gatekeepers are compared with Bergala's conception of the pedagogic
role of the passeur – a figure who also holds power in relation to young people's access to film and film-making, but one that connotes positive, even magical, properties.
'Ecole et cinéma': A national model for arts education in schools
Authors: Boutin Perrine
Published: May 2019

This essay presents the French educational programme 'Ecole et cinéma' in terms of its guiding principles. By examining the history of its creation, as well as the various levels at which this complex programme operates – from government agencies to pupils, by way of educators
and organizational leadership – we begin to understand the identification processes and values that the programme advocates, along with the contradictions that situate this rigorous and high-quality programme as a national apparatus that is representative of a certain idea of arts education.
But this is not without its own contradictions, which are inextricable from 'Ecole et cinéma', particularly at the present moment.
COMPONDO UMA HISTÓRIA DO PROJETO LOGOS II NO ESTADO DE RONDÔNIA (1970-1990)
Authors: Gromann de Gouveia Cristiane Talita , Brito Arlete de Jesus
Published: May 2019

Na década de 1970, em diversos estados do Brasil, foi implantado o Projeto Logos II. O objetivo desse projeto era habilitar professores sem formação, também conhecidos como leigos. No estado de Rondônia, o Logos II começou a funcionar em 1976, sendo que sua expansão para as cidades do interior ocorreu a partir da década de 1980. Diante desse quadro, este artigo tem como objetivo discutir e compor uma história de como se deu a implantação e o desenvolvimento do Projeto Logos II ao longo dos anos no estado de Rondônia. Como referencial teórico-metodológico, foram utilizados a triangulação de dados de Sandra Mathison (1988), o paradigma indiciário de Carlo Ginzburg (1989) e a crítica ao documento de Marc Bloch (2001). Os documentos que constituíram fontes foram compostos por módulos de ensino, legislações, fichas de matrículas, históricos escolares, diplomas, fotos de alunos e professores, além de outros documentos. Os resultados indicaram que o Projeto Logos II em Rondônia formou e habilitou muitos professores da zona rural, que passaram por diversas dificuldades para a realização do curso em função da falta de infraestrutura.

REPRESENTAÇÕES SOCIAIS DE DISCENTES DE PEDAGOGIA SOBRE O COMPONENTE CURRICULAR EDUCAÇÃO FÍSICA
Authors: Missias-Moreira Ramon , Nunes Anderson Souza
Published: May 2019

A Educação Física (EF) no ensino superior possui um caráter prático desportivo, a fim de proporcionar aos alunos uma diversidade de atividades, com o intuito de ampliar o conhecimento dos mesmos sobre a cultura corporal de movimento. Nesse sentido, esse estudo objetivou apreender as representações sociais de discentes do Curso de Pedagogia da Universidade Estadual do Sudoeste da Bahia (UESB) sobre os componentes curriculares EF I, II e III. Trata-se de um estudo descritivo-exploratório, de abordagem qualitativa. Realizou-se a entrevista semiestruturada com 38 discentes do Curso de Pedagogia da UESB, tendo os resultados sido analisados a partir da técnica de análise de conteúdo. Após análise dos conteúdos manifestos, as unidades de análise foram agrupadas em 3 categorias que expressam representações negativas dos estudantes universitários sobre os componentes curriculares EF I, II e III, a saber: Descompromisso Docente; Ausência da Importância da EF I, II e III; e, Obrigação Acadêmica. Desta forma, concluímos que os componentes curriculares, da forma como foram apresentados, solidificaram as representações sociais dos alunos, de forma aos mesmos apresentarem em suas manifestações vários aspectos que revelam que, por vezes, os componentes curriculares não foram tratados com a relevância que deveria, influenciando negativamente nas representações dos discentes.

Los sujetos transitivos e intransitivos con núcleo nominal común en español. Estructura y evolución (siglos XIII, XVI y XIX)
Authors: Bogard Sergio
Published: May 2019

Este trabajo ofrece una descripción del proceso de evolución sintáctica y semántica de los sujetos transitivos e intransitivos con núcleo nominal común en español. Con material español del siglo XIII, y español y mexicano de los siglos XVI y XIX, mostraré que, teniendo como punto de partida el orden más frecuente para ambos tipos de sujeto en el XIII, a saber, VS, el XVI ya presenta para el sujeto transitivo un orden dominante SV, en tanto que para el sujeto intransitivo, aunque el orden VS se mantiene como dominante, su productividad ha disminuido drásticamente. Finalmente, el siglo XIX exhibe el inicio de la consolidación del orden SV para ambos tipos de sujeto, dado que dicho orden ya constituye regla en ese momento en el caso del sujeto transitivo, y ya excede el 60% de aparición en el caso del sujeto intransitivo. Este último comportamiento nos proporciona, además, un nuevo argumento en favor de asumir el siglo XIX como el momento de inicio de una tercera etapa evolutiva en la historia del español, de acuerdo con la hipótesis de Melis, Flores y Bogard 2003.

Racial inequality and school failure of black students           
ABSTRACT. This article proposes a reflection on the importance of considering racial inequality as a phenomenon linked to school failure. The text is based mainly on references produced in the interface between psychology and education. At first, school failure was approached as a complex phenomenon, produced and reproduced from the influence of forces caused in the political, economic, social and institutional fields. Next, we sought to highlight the connections between racial and social inequality and the production of school failure, and to analyze the correlation between stigma, invisibility and silencing of black students. Finally, we considered the need to address the problem of racial inequality more effectively in understanding and coping with school failure.

Published: May 2019

A proposta do dossiê nasceu no contexto das atividades do “Núcleo de Estudos e Pesquisa em Educação, Desigualdade Social e Políticas Públicas” (Neped), da UFT, que vem desenvolvendo, desde 2015, no Tocantins, formação, estudos, pesquisa, debates e publicações que colocam em tela a relação Educação, Pobreza e Desigualdade Social (EPDS). Um das ações do núcleo se refere à organização e desenvolvimento de cursos como: o “Curso de Especialização Educação, Pobreza e Desigualdade Social”, que contribuiu com a formação e qualificação de mais de 300 profissionais que atuam na educação e/ou em contextos empobrecidos; e o “Curso de Aperfeiçoamento Educação, Pobreza e Desigualdade Social”, em fase de finalização e que formará cerca de 200 estudantes de graduação, profissionais da educação, ativistas de movimentos sociais, bem como profissionais de outras áreas afins. Citamos, também, nesse contexto, a pesquisa intitulada “As políticas educacionais no contexto das desigualdades sociais e da situação de pobreza e extrema pobreza no estado do Tocantins”, desenvolvida nos anos de 2016-2018; e a pesquisa “Trajetórias Escolares de estudantes em situação de pobreza na educação pública do Tocantins”, ainda em andamento. Outro importante trabalho foi a produção do vídeo-documentário “Educação e Pobreza no Tocantins” em 2017, que retrata a situação e a percepção de famílias beneficiárias do Programa Bolsa Família (PBF) e de profissionais que atuam nas escolas e na assistência social, no que concerne à importância desse programa para a educação das crianças em situação de pobreza.
A cerebral Arteriovenous Malformation mistakenly diagnosed as Dry Eye and Glaucoma: a case report
Authors: Shen Shuhao , Liu Xiaoyong , Chen Jian , Yang Chengyou , Shi Changzheng , Zhou Qing
Published: May 2019

Background

To report a case of a cerebral Arteriovenous Malformation(AVM) with eye symptoms firstly and review the characteristic of this case and the main confusing point for diagnosis of such case.

Case presentation

A 58-year-old women presented to the ophthalmology clinic with 1 and an half year of right eye redness, Ocular hypertension and recurrent headache. One and a half year ago she was diagnosed as right eye dry eye and glaucoma and had received treatment according to diagnosis, however all the treatment did not lead to any improvement of redness and headache. On physical examination, it revealed dry eye and severe corkscrew hyperemia with dilated vessels in the right eye. After we consider that the symptom may be related to intracranial abnormal vessels, Computed tomography angiography and venography (CTA+CTV) were performed and the results showed an arteriovenous malformation (AVM) of right parietal-occipital area in the brain. The AVM was definitely located by the further examination of Digital subtraction angiography (DSA). After the AVM endovascular embolism treatment, the conjunctival congestion of the right eye was significantly relieved and the intraocular pressure was decreased to normal.

Conclusion

In clinical practice, when found corkscrew hyperemia accompanied by neurological symptoms, it might be considered as a result from cerebral vessels diseases, so in this case ophthalmologists diagnosis should combine disease history and imaging examination.
Central nervous system vasculopathy caused by Fabry disease: a case report
Authors: Kong De-Zheng , Lian Ya-Hui , Wang Lin-Jing , Wang Chun-Mei , Meng Yang-Yang , Zhou Hong-Wei
Published: May 2019

Background:
Fabry disease is rare, and the diagnosis is often delayed. Here, we describe a case of Fabry disease resulting in vasculopathy of the central nervous system. Magnetic resonance (MR) black-blood sequence (three-dimensional T1 volumetric isotropic turbo spin echo acquisition), with the unique advantage of imaging the vascular wall, facilitated a clear identification of the vasculopathy.
Case presentation:
A 27-year-old man visited our hospital for the treatment of " double vision 6d." After a series of examinations, the patient was diagnosed with Fabry disease, which caused vasculopathy of the central nervous system. Subsequently, the patient was treated with corticosteroids and his symptoms were attenuated. Two months after the initial treatment, the initial lesion in the vascular vessel disappeared, however, a new lesion appeared. Similarly, four months after the initial treatment, although the previous lesion disappeared, a new lesion appeared.
Conclusions:
This case highlights that clinicians should use MR black-blood sequence scan in a timely manner in case of young patients with migratory lesions of brain. In case of detection of a vascular lesion in combination with other systemic lesions, the possibility of Fabry disease should be considered.
Transcriptomic and microstructural analyses in Liriodendron tulipifera Linn. reveal candidate genes involved in nectary development and nectar secretion
Authors: Liu Huanhuan , Ma Jikai , Li Huogen
Published: May 2019

Background

Nectar is a major flower attractant and reward for insects for pollination. Liriodendron, a genus of the Magnoliaceae family, has only two relict species, L. chinense and L. tulipifera, that are considered “basal angiosperms” according to plant evolutionary history. The flowers of Liriodendron plants are insect pollinated and secrete nectar to attract pollinators. To date, the morphology and anatomy of the nectary, the mechanism of nectar secretion and the molecular mechanism involved in nectary development in Liriodendron remain poorly understood.

Methods

In this study, we examined the nectary surface cells and the change in starch in L. tulipifera by using scanning electron microscopy and periodic acid-Schiff techniques to select definitive samples for next research. Transcriptome sequencing was performed on the top and middle parts of the immature nectary and the middle parts of the mature nectary and the postsecreted nectary in L. tulipifera. We evaluated the expression profiles of 22 DEGs that were closely related to nectary development and nectar secretion for real-time quantitative PCR analysis.

Results

The L. tulipifera nectary is a starch-storing nectary and is located in the top and middle parts of L. tulipifera petals. After analyzing the RNA-seq data, we obtained 115.26 Gb clean data in 12 libraries and mapped the results to the L. chinense reference genome with 71.02%-79.77% efficiency. In total, 26,955 DEGs were identified by analyzing six different pairwise comparisons. The flavonoid biosynthesis, phenylpropanoid biosynthesis, anthocyanin biosynthesis and starch and sucrose metabolism pathways were enriched and related to nectar secretion and pigment change. We identified 56 transcription factor families, and members of the TCP, Trihelix, C2H2, ERF, and MADS families changed dynamically during nectary development. Moreover, to further verify the accuracy of the RNA-seq results, we validated the expression profiles of 22 candidate genes.

Conclusions

We evaluated the nectary development and secretion process comprehensively and identified many related candidate genes in L. tulipifera. These findings suggest that the nectary may play important roles in flavonoid synthesis and petal color presentation.
Cultural and Social Life of Turkish Pasha in Belgrade – Example of Ali Riza Pasha
Authors: Leovac Danko
Published: May 2019

This paper focuses on the analysis of a very peculiar relationship of the last commander of the Belgrade fortress Ali Riza-Pasha towards the social and cultural life of the Serbian capital. Having in mind that the relations between the Serbs and Turks at the time were very specific, this pasha decided to break with the shackles of the past and became the first pasha up until that time to get himself fully immersed in the Serbian social life. He personally participated in numerous festivities, while his wife Meyra became known as the first wife of a pasha to organize parlour receptions for women from the upper echelons of the Serbian society at the time. Her oriental-themed salons left a deep mark on the society of the Serbian capital. Our goal in this paper is to present a folkloric and cultural dimension of the life of a Turkish pasha, but also the life at court by showing the activities of his wife.
“Turbo-folk Rocks!”: New Readings of Turbo-folk
Authors: Kulenović Nina , Banić Grubišić Ana
Published: May 2019

The subject of this paper is the ethnographic mapping of the origins of the new alternative scene, based on turbo-folk. Mainly located in Belgrade, this alternative scene has been swindling, over the last couple of years, as the circle of artists (Mangulica FM, Lenhart Tapes, Mega Denke, Gianni Druid, Bombe Devedesetih and others), who freely combine turbo-folk genre with other music forms (electronic music, rap and others) to fulfill modern audience needs. In this research, we will rely on the standpoint that the term “turbo-folk” is not only a tool for music genre’s description, but also a value connotated “floating signifier”, which pumps its content from the certain community’s symbolic repertoire. Turbo-folk showed its symbolic strength in the academic and non-academic discourse, as a tool for cultural switching on/switching off during the last decade of the twentieth century and the first decade of the twenty-first century, when it was instrumentalised as the constitutive otherness of “urban” (“elite”, “civilised”, “educated”, “cosmopolitan”) population. The basic assumption of this paper is that the disagreement about classifications, the focus of which is turbo-folk, is rehabilitated, recontextualized and revaluated. In this study, we will re-examine the hypothesis saying that the new alternative scene, which is the subject of this research, endeavours to instrumentalise turbo-folk as an arbor of “urban elite’s” cultural critique, its authority and legitimacy of its classification categories.
Representing the Yugoslav New Wave in the Documentary Film “The New Wave in Socialist Federal Republic of Yugoslavia as a Social Movement”
Authors: Ajduk Marija
Published: May 2019

This work explores the representation of the Yugoslav New Wave through the analysis of the documentary film “The New Wave in Socialist Federal Republic of Yugoslavia as a Social Movement”. Although the New Wave covers many spheres of art, in this analysis we will investigate it as the musical and cultural phenomena. The theoretical frame within the analysis is based on the idea that a documentary film can help us understand a particular period as well as reinvestigate it, and (re)construct it from a new. The results from this analysis should be able to show how the narrative about the New Wave continues to live thirty, forty years later, as well as how it inspires to (re)create and appoint with every new film made.
Between Heterotopy and Ideology: On the Realities of Reality TV in Serbia
Authors: Prodanović Srđan
Published: May 2019

In this paper we will try to explain the phenomenon of reality TV using Foucault's concept of heterotopia. First, we will consider some of the major theoretical dilemmas that go together with the emergence of this television format, which primarily concerns the degree of democratization of contemporary media, as well as the degree of exploitation of "ordinary actors". We will also claim that ambivalence and hybridity are an inherent feature of television, and that, as we will show in the second part, they can be more comprehensively theoretically understood if we approach them as a specific kind of heterotopia. We will then use the local modifications of the format in order to illustrate the way in which the heterotopic nature of the reality TV offers to its viewers a specific (quasi)reflection regarding the structural features of the giving society that, in fact, only contributes to its further fragmentation.
Beyond Asexualization: Narratives of Sexual Objectification of Persons with Albinism in Nigeria
Authors: Daniel Ikuomola Adediran
Published: May 2019

Often overemphasised, in most sexuality studies, is that persons with disability, especially women, face experiences of asexualization rather than sexualisation. Similarly overemphasised is the faulty monolithic assumption that economic deprivation is the causal factor in the objectification of persons with disability. This has unintentionally created an expectation that objectifying environments are the inevitable and immutable default to economic distress. This is often not the case within the socio-cultural space of persons with albinism (PWA) in Southern Nigeria, where their presence is obvious. As a departure, this study examined the sexual objectification of PWA in Nigeria. It was discovered that at some points in the life course of PWA, most especially among the women with the development and aging of their body, objectification added to mental health risks such as withdrawal syndrome, isolation and indolence. The study concludes that cultural attitudes not only creates and threatens PWA sexed and gendered body confidence in relationships but also for them to be labelled and misconstrued as sexually inactive.
Sob o Sol de Sobral - Uma Experiência que Transformou a Física e por Consequência a Cosmologia
Authors: De Carvalho Reinaldo Ramos , Teixeira Ramachrisna
Published: May 2019

Neste trabalho apresentamos uma revisão histórico-científica da importância da observação do eclipse solar ocorrido em Sobral em 1919. Revisamos alguns conceitos fundamentais que norteiam a história desta observação, que deu validade experimental à Teoria da Relatividade Geral (TRG). Considerando a importância que a observação teve na história da física, oferecemos uma narrativa que se inicia nos primórdios do pensamento humano, passando por diferentes épocas do nosso desenvolvimento como espécie até chegarmos aos estudos pré-Relatividade. A observação do eclipse de Sobral abriu novos horizontes na cosmologia, não só permitindo uma nova abordagem para o estudo do Universo em grande escala mas também por definir ferramentas que permitem mapear a distribuição de massa utilizando o fenômeno de lente gravitacional. Discutimos as medidas do desvio da luz de estrelas do aglomerado das Hyades e discorremos brevemente sobre a importância de uma revisão crítica da história da observação do eclipse e suas conseqüências para a qualidade da ciência que realizamos no país atualmente.
Lentes Gravitacionais: Um Rico Recurso Didático na Ocasião da Celebração dos 100 Anos do Eclipse de Sobral
Authors: Makler Martin
Published: May 2019

O efeito de lente gravitacional é uma das consequências mais espectaculares da deflexão da luz pela gravidade, medida pela primeira vez em Sobral e na Ilha de Príncipe em 1919. Apesar de sua grande beleza e das inúmeras aplicações na astrofísica — desde a descoberta de planetas extrassolares até a cosmologia — esse efeito está ausente dos currículos até da graduação em física. Nesta contribuição, abordaremos alguns aspectos de lentes gravitacionais que requerem apenas matemática elementar (i. e. sem cálculo diferencial e integral) para sua compreensão, sendo facilmente acessíveis a alunos de graduação em engenharias, ciências físicas e afins, e até mesmo alunos avançados do ensino médio. Em particular, apresentaremos soluções analíticas simples para imagens de fontes pontuais e para arcos gravitacionais gerados pelo campo gravitacional de objetos compactos e galáxias. Além de serem ilustrações simples e didáticas dos efeitos de lente gravitacional, esses exemplos permitem trabalhar diversos conceitos matemáticos.
The propagator of the finite XXZ spin-$\tfrac{1}{2}$ chain
Authors: Fehér Gyorgy , Pozsgay Balázs
Published: May 2019

We derive contour integral formulas for the real space propagator of
the spin-\tfrac1212
XXZ chain. The exact results are valid in any finite volume with
periodic boundary conditions, and for any value of the anisotropy
parameter. The integrals are on fixed contours, that are independent of
the Bethe Ansatz solution of the model and the string hypothesis. The
propagator is obtained by two different methods. First we compute it
through the spectral sum of a deformed model, and as a by-product we
also compute the propagator of the XXZ chain perturbed by a
Dzyaloshinskii-Moriya interaction term. As a second way we also compute
the propagator through a lattice path integral, which is evaluated
exactly utilizing the so-called FF-basis
in the mirror (or quantum) channel. The final expressions are similar to
the Yudson representation of the infinite volume propagator, with the
volume entering as a parameter. As an application of the propagator we
compute the Loschmidt amplitude for the quantum quench from a domain
wall state.
KİRA SÖZLEŞMESİNİN ŞERHİNİN HÜKÜM VE SONUÇLARI

Kira sözleşmesinin şerhi, TBK 312’de
düzenlenmiştir. TBK 310 ve 311’de kira sözleşmesinin kanuni devri
düzenlendikten sonra bu şerhin önemi büyük ölçüde azalmıştır. Azalan önemine
rağmen kira sözleşmesinin şerhinin, malikin TBK 350’ye, yeni malikin TBK 351’e
dayanarak kira sözleşmesini sona erdirme imkânını ortadan kaldıracağı için
halen anlam taşıdığı ifade edilmektedir. TMK 1009 çerçevesinde kira
sözleşmesinin şerhi, şerh edilen sözleşmenin kiracı tarafından taşınmazda
sonradan hak sahibi olan kişilere karşı da ileri sürülebilmesini sağlar. Bu
nedenle şerhi görerek taşınmazı iktisap etmiş yeni malikin TBK 351’e
dayanamayacağını savunmak yerindedir. Çünkü TBK 351, önceki malikin sahip olmadığı,
şerh edilen sözleşmede yer almayan, kiracının tabi olduğu sözleşme şartlarını
değiştiren yeni bir fesih imkânıdır. Fakat şerh, kira sözleşmesini şerh ettiren
malik ile kiracı arasındaki sözleşmenin tabi olduğu şartları değiştirmeyeceği
için kira sözleşmesi şerh edildiğinde hâlihazırdaki malikin TBK 350’ye
dayanamayacağının ileri sürülmesi makul değildir. Kira sözleşmesini şerh
ettiren malik gibi TBK 310 ve 311 çerçevesinde kira sözleşmesini kanunen
devralan kişiler de önceki malikin devredilen sözleşme çerçevesinde sahip
olduğu haklardan istifade edebilirler.

Development of an effective logistics infrastructure for companies contributes to ensuring their effective work, directly affects financial performance and requires the establishment of a management and accounting system for logistics costs. Classifying and registering logistics costs becomes more important in this regard. At this stage of Ukrainian accounting practice, there are challenges for logistics costs accounting such as their identification and registration. Methodological basis of study among different logistics concepts (concept of general logistics costs, concept of reengineering business processes in logistics, concept of an integrated logistics strategy, concept of supply chain management) was total logistics costs concept or the concept of full value as well as process-oriented approach. In the work, the generalization and formalization of existing approaches to the logistics costs accounting was made. Feasibility of using a process-oriented approach among other approaches (absorption costing, direct costing target costing, kaizen costing, etc.) were substantiated. The algorithm of identification and registration of logistics costs for Ukrainian enterprises was proposed. It is based on such inclusion in the relevant economic process (supply, production, sales and administration of logistics processes) and the use of a new consolidated account 29 “Logistics costs”. This authors’ approach to solving the problem of identification and registration of logistics costs for accounting purposes allows to optimize and increase the informativeness of accounting logistics costs reflection in Ukrainian accounting practice.

City image and self identity are two interrelated notions. Self identity, also referred to as urban related identity, is not solely derived from the physical characteristics of an urban space, but, consists of the social construction founded in the perception of individuals and groups (Lalli & Ploger, 1991). The relationship of the individual with a place is essential as place and space shape human experiences (Chen, 2012). With the trend of gated residential areas emerging in large cities such as Cairo and Alexandria in the late 90s creating a spatial discontinuity and urban fragmentation, this research is examining how open and gated urban residential areas shape place image of New Cairo’s Third Settlement residents.

Flood mapping is an important part of flood risk analysis and management as its result is the visualization of flood hazard in terms of flood depth and extent. However, flood mapping strongly depends on the selected modeling approach. Furthermore, model input data usually incorporate uncertainties that may vary significantly in time and space. In this study, the EBA4SUB (Event-Based Approach for Small and Ungauged Basins) hydrologic model and the one-dimensional HEC-RAS (Hydrologic Engineering Center's River Analysis System) hydraulic model were selected for evaluating their sensitivity, in terms of simulated flood area (FA) and volume (FV), to different combinations of input parameters. Results of hydrologic modeling highlight the great variation of design peak discharges which strongly influence the modeled FA and FV. The sensitivity of FA and FV to excess rainfall determination was several times larger than the sensitivity to the routing propagation for two assumed gross rainfall distributions (rectangular and Chicago), which highlights the importance of the correct estimation of soil and land use properties affecting the infiltration estimation. Moreover, the sensitivity of FA and FV to the roughness parameter was 1.5–2 times greater than the sensitivity to the cross-section parameter, yet, stressing the importance of input parameters for hydraulic modeling.

Biofouling is a critical issue in the membrane separation process as it can increase the operational cost by lower down membrane permeability. Covalent binding of an antibacterial agent on the membrane surface to kill microorganisms to hinder biofouling formation process draws great attention. In this study, we used three kinds of capsaicin derivatives, MBHBA, HMBA, and HMOBA, to fabricate antibiofouling membrane via UV-assisted photo grafting method. The influence of these capsaicin derivatives on membrane properties was investigated and compared. The results suggest that HMBA showed the best UV activity, followed by HMOBA and MBHBA successively. Due to the difference of functional groups among capsaicin derivatives, there is an increase in membrane wettability of HMBA and HMOBA-modified membranes, while there is a decrease for MBHBA-modified membrane. MBHBA-modified membrane showed enhanced irreversible fouling, which is in contrast to that of HMBA- and HMOBA-modified membranes. The modified membranes showed similar antibacterial activity against Escherichia coli. The practicability of the modified membranes was examined by dipping them into tap water and seawater for 30 days, and the results displayed the modified surfaces have the potential to relieve biofouling for separation membranes.

Klinisch linguïsten gebruiken in de diagnostische fase voor de beoordeling van de spontane taal bij afasie veelal de Analyse voor Spontane Taal bij Afasie (ASTA). Het meest recente ASTA-protocol uit 2013 bestaat uit twaalf linguïstische taalmaten. In dit artikel worden twee kleinschalige en exploratieve onderzoeken naar zestien nieuwe communicatieve en linguïstische taalmaten beschreven. De onderzoeksvraag hierbij is, in hoeverre deze taalmaten een waardevolle toevoeging zouden kunnen zijn op de huidige ASTA maten. De uitgevoerde groepsvergelijkingen met de nieuwe maten tonen aan dat mensen met afasie significant afwijkend scoren op de maten ‘woorden exclusief linguïst’,‘pauzes’, ‘valse starts’, ‘onvolledige uitingen’, ‘geëxcludeerde woorden’, ‘relevantie antwoord’, ‘stereotypen’, ‘koppelwerkwoorden’ en ‘bijvoeglijke naamwoorden’ ten opzichte van gezonde taalsprekers. In de discussie zal verder ingegaan worden welke van deze negen maten daadwerkelijk klinisch relevant zijn om toe te voegen aan de huidige maten van de ASTA. Met meer maten kan, indien nodig, de spontane taal bij mensen met afasie specifieker geanalyseerd worden waardoor een meer op maat behandeladvies mogelijk is.
Combining Contextualized Embeddings and Prior Knowledge for Clinical Named Entity Recognition: Evaluation Study (Preprint)
Authors: Jiang Min , Sanger Todd , Liu Xiong
Published: May 2019

BACKGROUND

Named entity recognition (NER) is a key step in clinical natural language processing (NLP). Traditionally, rule-based systems leverage prior knowledge to define rules to identify named entities. Recently, deep learning–based NER systems have become more and more popular. Contextualized word embedding, as a new type of representation of the word, has been proposed to dynamically capture word sense using context information and has proven successful in many deep learning–based systems in either general domain or medical domain. However, there are very few studies that investigate the effects of combining multiple contextualized embeddings and prior knowledge on the clinical NER task.

OBJECTIVE

This study aims to improve the performance of NER in clinical text by combining multiple contextual embeddings and prior knowledge.

METHODS

In this study, we investigate the effects of combining multiple contextualized word embeddings with classic word embedding in deep neural networks to predict named entities in clinical text. We also investigate whether using a semantic lexicon could further improve the performance of the clinical NER system.

RESULTS

By combining contextualized embeddings such as ELMo and Flair, our system achieves the F-1 score of 87.30% when only training based on a portion of the 2010 Informatics for Integrating Biology and the Bedside NER task dataset. After incorporating the medical lexicon into the word embedding, the F-1 score was further increased to 87.44%. Another finding was that our system still could achieve an F-1 score of 85.36% when the size of the training data was reduced to 40%.

CONCLUSIONS

Combined contextualized embedding could be beneficial for the clinical NER task. Moreover, the semantic lexicon could be used to further improve the performance of the clinical NER system.

Soil pollution with Heavy Metals (HMs) has been of much interests lately and is one of the major issues to be faced globally and requires attention because heavy metals above their normal ranges are extremely threatened to both biotic and abiotic life. It was therefore of interest to conduct study to assess the extent of heavy-metal contamination of soils within battery technicians’ workshops within Ilorin metropolis, Kwara State, Nigeria. A total of twenty-five composite soil samples were collected from six selected battery charger workshop within Ilorin metropolis and analyzed for the presence of heavy metals using atomic absorption spectrophotometer. Result reveals significant positive relationship between Mn and Fe (r=0.511**, p<0.001), Mn and Cu (r=0.565**, p<0.001), Fe and Cr (r=0.895**, p<0.001), Fe and Cu (r=0.823**, p<0.001) and between Cr and Cu (r=830**, p<0.001). Result also shows significant negative relationship between Mn and Cr (r=-0.679**, p<0.001), Pb and Cu (r=-0.468*, p<0.05) respectively. The pollution status of heavy metals in soils was evaluated using quantitative indices (pollution index–PI). The result shows that Zn was moderately contaminated while other heavy metals (Pb, Cd, Cr and Cu) had very slight contamination (pollution index<0.1). The Ilorin metropolis soils of Kwara State were found to have a moderate to very slight contamination respectively. Large variations in PI values of Zn revealed that soil in those areas of the city, which are influenced by anthropogenic activities, have moderate concentrations of Zn resulting in “considerable risk”. The findings of this study recommend comprehensive continuous annual monitoring and auditing and further studies on the level of these heavy metals in the near future to ascertain long-term effects of anthropogenic impact is forestalled to protect the men and the environment. This should also involve larger coverage with studies on ground water around such locations. Furthermore, continuous metals speciation should be carried out so that the form and extent of metal bioavailability can be evaluated further.
