Authors: Patel Ankit , Mishra Chandravadan B.
Published: January 2018

In India, increase in population coupled with heavy laden loads of vehicles conveying heavier stresses concentrates especially on roads running in clayey soil zones which create significant problems for pavements and hence need to be stabilized. Insecure soils make huge issues for asphalts and henceforth should be settled. In this study, at first the examination of normal soil is done to assess the physical and engineering properties as indicated by Indian Standard (1498 – 1970) by coordinating exploration focus tests and to evaluate the adjustment in properties by the utilizing sea shell powder as a part of dose of 12%, 15% and 18% as stabilizers to be used as a part of the asphalt configuration for the economy. Understanding the progressions in sub- grade quality, the correct outline systems of the asphalt layers based upon the sub grade quality can be worked out utilizing IRC code and comparative saving cost per km.
Analysis of EFL Writing in Secondary Education
Authors: Lahuerta-Martínez Ana Cristina
Published: January 2018

The aim of this paper is to examine secondary education learners’ performance in L2 writing production using the complexity, accuracy, and fluency constructs. Results show that the measures of fluency, accuracy, grammatical and lexical complexity progress in a significant way: fourth grade students outperform first graders in the aforementioned measures. Secondly, fewer correlations between the writing measures used and the general quality of the compositions are found among the older students than among the younger ones, indicating that the correlations change depending on learners’ age. Thirdly, 1st year students exhibit a higher ratio of errors, both in general and also by error category, although only two types decrease significantly in 4th year students: syntactic and spelling errors. Lastly, we find that errors tend to develop in a non-linear way.

Authors: Medrouk Lisa , Pappa Anna , Hallou Jugurtha
Published: January 2018

We present a method of automaticaly extracting and gathering specific data text from web pages, creating a thematic corpus of reviews for opinion mining and sentiment analysis. The internet is an immense source of machine-readable texts \cite{mcenery1996} suitable for linguistic corpus studies\cite{Fletcher04}\cite{Kilgarriff2003}. Though, specific tools of web information extraction research domain as well as from the NLP do not include an open source system able to provide a thematic corpus according to an end-user request\cite{Sharoff2006}.\\ The need of use natural texts as databank for opinion mining and sentiment analysis is increased since the expansion of the digital interaction between users and blogs, forums and social networks.\\ The RevScrap system is designed to provide an intuitive, easy-to-use interface able to extract specific information from accurate web pages returned by search engine's request and create a corpus composed by comments, reviews, opinions, as expressed by users' experience and feedback. The corpus is well structured in xml documents, reflected Singler's design criteria\cite{sinclair01}..
Effect of Gradation and Particle Size on Correlations between DCP Index (ASTM D6951 – 03) and Relative Density for Sand
Authors: Katakiya Mehul , Parekh Ami
Published: January 2018

This research study was mainly focus on performing dynamic cone penetration tests according to ASTM D691 - 03 with various relative density on different gradation (poorly graded and well graded) of sand. Sand samples were collected from different region of Gujarat viz. Khanpur, Sevaliya, Ahmedabad. Well graded sand samples were prepared by mixing in different proportions of sand samples collected from above locations. Dynamic cone penetration tests were carried out in Plexiglas tank (60 cm × 60 cm × 75 cm) on three different poorly graded and three different well graded sand at different relative density of 30, 50, 65, 75 %. Relative density of sand samples were determined according to IS : 2720 (Part 14) – 1983. Dry sand has been filled in tank up to 70 cm height of tank. Tamping was done with rammer (30 cm × 30 cm × 1 cm) of 9.5 kg weight to achieve desired density. Desired depth of penetration is 60 cm. Dynamic cone penetration tests were performed according to ASTM D6951-03.
Formalization of some central theorems in combinatorics of finite sets
Authors: Singh Abhishek Kr
Published: January 2018

We present fully formalized proofs of some central theorems from combinatorics. These are Dilworth's decomposition theorem, Mirsky's theorem, Hall's marriage theorem and the Erdős-Szekeres theorem. Dilworth's decomposition theorem is the key result among these. It states that in any finite partially ordered set (poset), the size of a smallest chain cover and a largest antichain are the same. Mirsky's theorem is a dual of Dilworth's decomposition theorem, which states that in any finite poset, the size of a smallest antichain cover and a largest chain are the same. We use Dilworth's theorem in the proofs of Hall's Marriage theorem and the Erdős-Szekeres theorem. The combinatorial objects involved in these theorems are sets and sequences. All the proofs are formalized in the Coq proof assistant. We develop a library of definitions and facts that can be used as a framework for formalizing other theorems on finite posets.
A Comparative Study of Effectiveness of Steel Plate Shear Wall Patterns in Steel Building
Authors: Patel Kavin , Patel Dipali
Published: January 2018

Steel buildings prone to lateral loads responds well if provided with SPSW. SPSW is more effective for lateral loads as they are more ductile, lighter and lesser space occupants. SPSW systems are used in high-rise buildings as retrofitting also. Now a days conventional SPSW are more preferred in steel buildings. By keeping the view in mind, an effort has been made to check the effectiveness of different patterns of SPSW. For the same, bare-frame is compared with Conventional SPSW, X–type SPSW and Diagonal SPSW. Strip modelling is used to analyse SPSW in building using ETABS software. The load considered are primary loads and earthquake load as Static coefficient method from IS 1893:2002. The maximum displacement and axial forces are compared to get effective pattern.
A Corpus-Driven Approach to Sentiment Analysis of Patient Narratives
Authors: Stuart Keith , Botella Ana , Ferri-Miralles Imma
Published: January 2018

This paper describes the linguistic analysis of a corpus of patient narratives that was used to develop and test software to carry out sentiment analysis on the aforementioned corpus. There is a growing body of research on the relationship between sentiment analysis, social media (for example, Twitter) and health care, but less research on sentiment analysis of patient narratives (being longer and more complex texts). The motivation for this research is that patient narratives of experiences of the National Health Service (NHS) in the UK provide rich data of the treatment received.

The corpus threw up some unexpected results that may be of benefit for researchers of sentiment analysis. The linguistic problems encountered have been divided into three sections: the noisy nature of large corpora; the idiomatic nature of language; the nature of language in the clinical domain. This article gives an overview of the project and describes the linguistic problems that arose out of the project, which tried to find a means to automate the analysis of patient feedback on health services.
Counterexample-Guided Abstraction-Refinement for Hybrid Systems Diagnosability Analysis
Authors: Zaatiti Hadi , Ye Lina , Dague Philippe , Gallois Jean-Pierre
Published: January 2018

Verifying behavioral or safety properties of hybrid systems, either at design stage such as state reachability and diagnosability, or on-line such as fault detection and isolation is a challenging task. We are concerned here with abstractions oriented towards hybrid systems diagnosability checking. The verification can be done on the abstraction by classical methods developed for discrete event systems extended with time constraints, which provide a counterexample in case of non-diagnosability. The absence of such a counterexample proves the diagnosability of the original hybrid system. In the presence of a counterexample, the first step is to check if it is not a spurious effect of the abstraction and actually exists for the hybrid system, witnessing thus non-diagnosability. Otherwise, we show how to refine the abstraction, guided by the elimination of the counterexample, and continue the process of looking for another counterexample until either a final result is obtained or we reach an inconclusive verdict. We make use of qualitative modeling and reasoning to compute discrete abstractions. Abstractions as timed automata are particularly studied as they allow one to handle time constraints that can be captured at a qualitative level from the hybrid system.
The Effects of Structure and Proficiency on Determiner Number (Dis)agreement in the Nigerian English Noun Phrase
Authors: Akinlotan Mayowa
Published: January 2018

The paper investigates the extent to which the grammatical number (dis)agreement hypothesis in the New Englishes (Platt et al 1984, Gorlach 1998, Mesthrie et al 2008) manifests in the determiner system of the Nigerian English, and how the variables of proficiency, text type, register, structural complexity, and syntactic form influence scenarios found. Applying principle of accountability (Labov 1972, Tagliamonte 2012), together with test statistic on data drawn from the Nigeria-ICE, we showed that in Nigerian determiner system, grammatical number is likely to agree (98%) with the head noun of the noun phrase than to disagree (2%). Also, the disagreement is mainly influenced by complexity and proficiency. This number irregularity is more likely to occur with the use of quantifier or demonstrative than with indefinite article. We argue that this scenario suggests a manifestation of fossilisation by transferring from the syntactically unique determiner systems of the local Nigerian languages to Nigerian English.
Semiotic Modes in the Organization of Lectures in English and in Spanish
Authors: Bernad-Mechó Edgar , Fortanet-Gómez Inmaculada
Published: January 2018

This paper aims at describing from a multimodal discourse analysis perspective, the organizational metadiscourse elements (and previewing and reviewing instances in particular) employed in academic lectures in English and in Spanish in order to connect speech events and structure the discourse. We believe that a multimodal approach (Fortanet-Gómez & Ruiz-Madrid, 2014; Querol-Julián, 2010; Querol-Julián & Fortanet-Gómez, 2012) provides a deeper understanding of how meaning is conveyed not only through linguistic elements but also through non-verbal items like paralanguage and kinesics.

In order to carry out this study we selected two lectures in English from an African American Studies course which is part of Yale University’s collection of OpenCourseWare, and two lectures in Spanish from a Human Resources Studies course recorded at Universitat Jaume I. With the aim to describe possible recurrent patterns and relationships between verbal and non-verbal (paralinguistic and kinesic) elements, we will carry out a MDA in three phases: a linguistic transcription and identification of organizational metadiscourse using Ädel's (2006, 2010) model and taxonomy of metadiscourse for spoken academic English; a transcription of paralinguistic features (syllabic duration and loudness) and kinesic elements (hand-arm gestures); and an analysis of co-occurrences of modes to understand how meaning is conveyed.

The final objective of this study is twofold, i) to approach multimodal academic discourse from a contrastive perspective and ii) to use the results for EAP training courses for Spanish teachers and students, as it has been observed that verbal and non-verbal discourse needs awareness raising in order to facilitate transfer from mother tongue to another language.
Cultural Values and Interpersonality in Spanish and British university websites
Authors: Ivorra-Pérez Francisco Miguel
Published: January 2018

The aim of this paper is to study the impact of Spaniards’ and Britons’ index of individualistic cultural values (Hofstede, 1991) on the type of engagement markers (Hyland and Tse, 2004) used in Peninsular-Spanish and British university websites along with the English translated version of the former. The cultural dimension of individualism is related to the way in which individuals from a particular culture define their own identity and their relationship with other people. As regards engagement markers, these are used to establish a social interaction in the online encounter held between universities and prospective students who may wish to study in these institutions. Following an observational and a quantitative analysis, the findings reveal important statistical differences in the three corpora analysed and show that culture and engagement markers may be considered intertwined concepts. The results obtained may be a valuable source of information for Peninsular-Spanish universities as they may help them not only to translate into English the Spanish version of their websites but also to adapt the appropriate engagement markers taking into account the British cultural framework.
Utilization of Quarry Dust as Fine Aggregates in Concrete
Authors: Agrawal Vishal , Shah Pankil , Gupta Arman , Shah Rahul
Published: January 2018

In the view of the expeditious growth of infrastructure around the globe, there is an acute shortage of building materials and also a very stern problem of the disposal of the remaining and continuously generating waste. The demand of natural sand in the construction industry also has magnificently increased resulting in the rapid depletion of the river beds which are the natural sources of sand. Acute shortage of good quality of sand has resulted in to considerable increase in its price ultimately affecting the construction cost. Thus there is a severe need to identify a suitable substitute of sand which is eco-friendly and can be used effectively in construction practices mainly in concrete which requires sand as fine aggregates. An attempt is required to investigate use of some alternative materials to save precious natural resources. The current study focuses on determining suitability of using quarry dust, which is a waste product from quarry, as fine aggregates in traditional concrete. During the tenure of the study, some physical and engineering properties of quarry dust and sand were determined and compared. The compressive strength of concrete was determined after replacing sand with quarry dust in various ratios. The results of the study showed encouraging results for replacement of 50% of sand with quarry dust.
English as a lingua franca on the International Campus of Excellence: initiatives and outcomes
Authors: Bocanegra-Valle Ana
Published: January 2018

This paper draws on two policy documents, the “International Campus of Excellence Initiative” and the “University Strategy 2010-2015” to assess the level of internationalisation of the Spanish university system as portrayed by the international campuses of excellence (ICEs). It sets out to identify the role and use of English as a lingua franca with academic purposes across Spanish ICEs and the initiatives developed based on the use of English as a communication tool in this academic context. The investigation draws on textual data gathered from the websites of two Spanish-based ICEs, such as Ceimar (ICE on Marine Science) and Iberus (ICE of the Ebro Valley). The website analysis shows that these two ICEs rely on English to implement issues of internationality in their academic offer and articulate a diversity of actions and programmes in which English is used as the lingua franca for international communication and academic teaching as well as for the dissemination of research activities.
A French Weblog Corpus for New Insights on Blog Post Tagging
Authors: Garrido-Marquez Ivan , Audibert Laurent , García-Flores Jorge , Lévy François , Nazarenko Adeline
Published: January 2018

The rapid evolution and informational growth of blogs requires enhanced functionality for searching, navigating and linking content. This paper presents the French Blog Annotation Corpus \textsc{FLOG}, intended to provide a research testbed for the study of annotation practices, and specifically tagging and categorizing blog posts. The corpus covers a ten year time span of blog posts on cooking, law, video games and technology. Statistical analysis of the corpus suggests that tag annotation of posts is more frequent than category attribution, but on the other hand categories provide a richer semantic structure for post classification and search. The review of the state of the art on automatic tag suggestion shows that tag suggestion tools are not of widespread use yet between bloggers, which might be a consequence of methods that do not take into account the past tagging history of the blog, the context of the post within the blog and the tagging pattern of each blog author.

Authors: Agrawal Manish , Rahman Quazi Billur , Naulakha Deependra , Karki Riwaj
Published: January 2018

Introduction: Third molar extraction is the most commonly performed procedure by oral and maxillofacial surgeons and most of the extraction leads to minimum pre and post operative difficulties if proper preoperative planning is done and if surgical principles are strictly followed.Objective: This study evaluated whether pre and post operative pain and trismus were related to difficulty of surgery.Methodology: Total number of patients included in this study were 266 (male 135 and female 131), age range from 18 to 34 years. Preoperative diagnosis was made by clinical examination and radiographs. Clinical examination was done to determine pain, swelling and mucosal coverage of tooth whereas OPG and RVG were taken to assess the angulations, level of tooth impaction and bony coverage of tooth. Standardized technique was used for tooth extraction; buccal guttering, adequate elevation, reflection of mucoperiosteal flap, crown sectioning and ostectomy. Evaluation of pain and trismus was done preoperatively, on first and third post operative day. SPSS version 16 was used to analyse the data. Chi square (x²) test and unpaired 't' test were done. Modified Parant Scale was used to evaluate the difficulty of tooth extraction; Group I: forceps extraction; Group II: ostectomy; Group Ill: ostectomy and crown sectioning; Group IV: difficult extraction.Results: When both preoperative and postoperative results were compared after data analysis, pain was significantly reduced and significant inter incisal opening was achieved, in both the groups P > 0.05. The results were statistically not significant.Conclusion: Postoperative pain and trismus was minimum in (Group I) then in (Group II to IV). The incidence of postoperative pain and trismus among all the groups were more or less similar. Hence, no significant difference was found. Birat Journal of Health SciencesVol.2/No.3/Issue 4/Sep- Dec 2017, Page: 282-286
Repetition of Therapeutic Pinning By a Mentally Challenged: A Case Report and a Medico-Legal Lesson Learnt from Kathmandu Medical College and Teaching Hospital, Kathmandu, Nepal
Authors: Barnawal Siddhartha , Acharya Jenash
Published: January 2018

We present an unusual case of a 27 year-old-female with undiagnosed mental illness who presented with pricking type of tenderness in and around umbilicus and lower left quadrant of left breast. X-ray revealed the presence of sewing needles on those areas. The foreign body was inserted deliberately by the patient herself on trying to mimic the FNAC procedure performed on her a day before. Under C-arm guidance both the needles were located and extracted. Insertion of foreign body via abdominal wall is the first published report to our knowledge. Performing an invasive procedure in front of a mentally challenged individual requires precaution as a clinician, is an important lesson learned. Birat Journal of Health SciencesVol.2/No.3/Issue 4/Sep- Dec 2017, Page: 303-305
A Rare Case Study of Torsion of a Non-Gravid Uterus

Published: January 2018

Torsion of a non gravid uterus is a rare but potentially fatal event. It may lead to rapid clinical deterioration causing irreversible ischemic damage to the uterus. The rarity of the condition and its non specific clinical presentation make the clinical diagnosis difficult. In this report we discuss a case of uterine torsion in a 55 year old postmenopausal lady who presented in emergency with acute abdomen. On examination a huge abdominal mass arising from pelvis was noted. The operative finding was huge fundal myoma with uterine torsion.Birat Journal of Health SciencesVol.2/No.3/Issue 4/Sep- Dec 2017, Page: 309-311
Albert Dereymaeker and Joseph Cyriel Mulier’s description of anterior cervical discectomy with fusion in 1955
Authors: Bartels Ronald H. M. A. , Goffin Jan
Published: January 2018

Anterior cervical discectomy with fusion (ACDF) is a very well-known and often-performed procedure in the practice of spine surgeons. The earliest descriptions of the technique have always been attributed to Cloward, Smith, and Robinson. However, in the French literature, this procedure was also described by others during the exact same time period (in the 1950s).

At a meeting in Paris in 1955, Belgians Albert Dereymaeker and Joseph Cyriel Mulier, a neurosurgeon and an orthopedic surgeon, respectively, described the technique that involved an anterior cervical discectomy and the placement of an iliac crest graft in the intervertebral disc space. In 1956, a summary of their oral presentation was published, and a subsequent paper—an illustrated description of the technique and the details of a larger case series with a 3.5-year follow-up period—followed in 1958.

The list of authors who first described ACDF should be completed by adding Dereymaeker’s and Mulier’s names. They made an important contribution to the practice of spinal surgery that was not generally known because they published in French.
Combinatorial efficacy of Trichoderma spp. and Pseudomonas fluorescens to enhance suppression of cell wall degrading enzymes produced by Fusarium wilt of Arachis hypogaea.L
Authors: Rajeswari P , Kapoor R
Published: January 2018

Fusarium oxysporum, the soil borne pathogen causes vascular wilt, on majority of crop plants. It has been demonstrated that two different species of Trichoderma and Pseudomonas fluorescens suppress disease by different mechanisms. Therefore, application of a mixture of these biocontrol agents, and thus of several suppressive mechanisms, may represent a viable control strategy. A necessity for biocontrol by combinations of biocontrol agents can be the compatibility of the co-inoculated micro-organisms. Hence, compatibility between Trichoderma spp. and Pseudomonas fluorescens that have the ability to suppress Fusarium oxysporum in vitro on the activity of pectinolytic enzymes of Fusarium oxysporum. The activity of pectinolytic enzymes, i.e. pectin methyl esterase, endo and exo polymethylgalacturonases and exo and endo pectin trans eliminases produced by Fusarium oxysporum (Control) was higher. Maximum inhibition of pectin methylesterase, exo and endo polymethylgalacturonase and exo and endopectin trans eliminase was shown by culture filtrate of Trichoderma viride + Pseudomonas fluorescens (Tv+Pf) (1+2%), followed by Trichoderma harzianum + Pseudomonas fluorescens, (Th +Pf) (1.5+2%) and Trichoderma viride + Trichoderma harzianum (Tv+Th) (1+1.5%). However, pathogenecity suppression of Fusarium oxysporum, a causative of Arachis hypogaea. L by the compatible combination of Trichodema viride + Pseudomonas fluorescens (1+2%) was significantly better as compared to the single bio-agent. This indicates that specific interactions between biocontrol agents influence suppression of pathogenicity factors directly by combinations of these compatible bio-agents.Int. J. Agril. Res.

Identités marchandes. Merciers et hommes d'affaires dans le commerce entre les Pays-Bas et l'Espagne (1533-1556)
Authors: Brumont Francis , Priotti Jean-Philippe
Published: January 2018

Outre la publication d'une correspondance inédite entre des merciers navarrais fréquentant les foires de Castille et de grands marchands internationaux résidant aux Pays-Bas, les auteurs étudient dans l'introduction à ces lettres de nombreux aspects des liens personnels et commerciaux qui unissent cette province et le royaume de Castille. Ils s'intéressent en premier lieu aux hommes d'affaires établis à Anvers (émigrés béarnais, castillans et basques), à leurs interrelations, aux liens maintenus avec leur patrie d'origine ainsi qu'à leur stratégie d'ascension sociale en terre d'accueil. Les petits merciers, sans envergure comparable, recourent à leur protection, à leur financement et à leur médiation pour amplifier le champ de leur activité, et imbriquent de cette façon grand négoce et commerce de détail. Déconvenues et conflits s'ensuivent. Sont également abordés les aspects proprement économiques de ces échanges : marchandises, trajets, système des foires, crédit et changes, les missives publiées permettant une analyse fine de la conjoncture et des répercussions des décisions politiques sur la vie commerciale et même sur la vie privée des acteurs, tout comme sur leur univers mental, dont la correspondance donne un aperçu très vivant.
Le rite russe de la distribution du destin
Authors: Bajburin Albert
Published: January 2018

L'auteur reprend la notion de destinée (dolja) pour l'étudier du point de vue ethnographique. En particulier, si le destin est un lot donné à chacun par Dieu, il existe aussi un destin commun à chaque groupe social. Par conséquent, les rites de passage liés au cycle de la vie ont une fonction de redistribution du destin commun, à chaque fois qu'un membre d'un groupe change de statut social, c'est à dire, à chaque naissance, mariage ou décès.

La fourrure.

Vilipendée par les prédicateurs, la passion pour la fourrure n'en a pas moins marqué les rites comme la langue. Symbole de richesse, la toison (généralement de mouton) est présente dans les rites du mariage et de la naissance, accompagne la vente du bétail. Image de fertilité, la fourrure est source de métaphores du sexe féminin. Enfin, associée de façon générale à la prospérité, elle est un élément de divination.
