Abstract

Background: Epidemiological studies have reported an increasing prevalence of tooth wear, and general dental practitioners see a greater number of patients seeking treatment with worn dentition. Improper oral hygiene, unhealthy habits, occupational hazards, and potentially erosive processed foods seem to play a major role in the non-carious loss of dental hard tissue. The aim of this study is to assess the factors and cofactors that may play a major role in the genesis of dental attrition, dental abrasion, and, especially, dental erosion.

Material and methods: Seventy-nine consecutive patients, aged between 17 and 78 years, have enrolled in our study, completing a questionnaire regarding chronic illnesses, eating habits, and dental hygiene, followed by a dental clinical examination.

Results: The male-female ratio was 1.4:1, with a mean age of 35.6 years. Forty-four (55.7%) patients presented objective signs of tooth wear. Regarding oral hygiene habits, the use of a hard toothbrush is linked to increased tooth wear, while brushing in a circular motion seems to be the least abrasive. We found a considerable prevalence of bruxism (19%), which led to severe generalized attrition in almost half of such patients. The most popular drinks with erosive potential were coffee (58.2%), soft drinks (57%), and tea (24.1%), and extrinsic erosion was more frequent in patients younger than 30 years. Understandably, physiological tooth wear was more common in older patients. The questionnaire revealed that over 60% of patients have inaccurate knowledge of tooth wear.

Conclusions: Tooth wear is partially a progressive physiological process. Unfortunately, we see it increasing in younger patients due to pathological influencing factors. These include improper tooth brushing technique and materials, bruxism, dental prosthesis, dietary habits. Primordial and primary prevention is the key to reducing morbidity, health education being an essential part of it.

Abstract
The current practice in the field of forensic medicine imposes the use of modern investigation techniques. The complexity of laboratory investigation methods needed for a final result of the investigation in forensic medicine needed new biomarkers of higher specificity and selectivity. Such biomarkers are the microRNAs (miRNAs), short, non-coding RNAs composed of 19–24 nucleotides. Their characteristics, such as high stability, selectivity, and specificity for biological fluids, differ from tissue to tissue and for certain pathologies, turning them into the ideal candidate for laboratory techniques used in forensic medicine. In this paper, we wish to highlight the biochemical properties and the usefulness of miRNAs in forensic medicine.
Gas-phase high-resolution molecular spectroscopy for LAV molecules
Authors: Gulaczyk Iwona 
Published: November 2017

Abstract
High-resolution infrared (IR) spectroscopy is essential to the analysis of molecular rotation-vibration spectra. The high-resolution spectra deliver much information about structure and dynamic of molecules, but often they are very complex. For nonrigid molecules the complexity arises from transition tunneling splittings. Methylamine is a classic example of a nonrigid molecule in which two large amplitude motions, inversion and torsion, occur simultaneously. It has six equivalent potential minima, for which an effective vibration-inversion-torsion-rotation Hamiltonian has been developed. In the chapter assignment and analysis of several spectral regions of methylamine have been briefly presented explaining the assigning techniques and theoretical treatment of experimental lines.

Abstract
Nasal meningoencephaloceles are rare findings, represented by protrusions of intracranial contents into the nasal cavity. They present as unilateral masses, and commonly determine unilateral nasal obstruction, rhinorrhea and non-characteristic headaches.
We present the case of a 34-year-old patient diagnosed with a posttraumatic transethmoidal meningoencephalocele. The patient presented with unilateral nasal obstruction, mild headache and episodic watery rhinorrhea. The treatment was endoscopic endonasal surgical excision and repair of the skull base defect, in a mixt ENT-neurosurgical team. Patient follow-up showed no remaining mass or symptoms and normal closure of the skull base defect.

Abstract
Sinoliths are rarely found calculi of paranasal sinuses. The most rarely they were found in the sphenoidal sinuses. At a routine Cone Beam CT exam of a 52-year-old male patient clinically silent small sinoliths were found bilaterally in the sphenoidal sinuses and a larger posterior ethmoidal sinolith was found on the right side. To our knowledge, such multiple sinuses involvement has not been previously reported.
La part sémiotique de l’anthropologie des modernes
Authors: Couégnas Nicolas , Famy Aurore 
Published: November 2017

Résumé
Les propositions de Bruno Latour, qui ont trouvé une forme d’achèvement dans l’Enquête sur les modes d’existence, offrent à la sémiotique greimassienne, et post-greimassienne, une voie de développement extrêmement fructueuse et novatrice, susceptible de fournir les fondements d’une « anthropo-sémiotique des modernes ». Il ne s’agit pas d’adopter sans discussion les propositions du sociologique, ni de les traduire dans l’appareil sémiotique de l’Ecole de Paris, mais d’exploiter la part foncièrement sémiotique de ces propositions. Une première phase de la recherche, montre que chacun des quinze modes d’existence décrits par Latour, qui structurent le champ social en domaines (la science, le droit, la fiction, la technique, la politique, etc.), mobilise une scène actantielle spécifique et repose sur une composante énonciative, de l’ordre de l’effectuation qui confère au mode d’existence son poids existentiel. Deuxième phase de la réflexion, la part sémiotique inhérente aux modes d’existence donne en quelque sorte les moyens de leur dépassement par la sémiotique elle-même. Il appert en effet que l’on peut identifier, derrière chacun des modes d’existence, une sémiose particulière. Ce dernier point, fondamental, conduit à ébaucher les traits d’une anthropo-sémiotique qui interroge l’économie générale de la théorie sémiotique post-greimassienne.
Effects of Surface Roughness and Non-Newtonian Micropolar Fluid Squeeze Film between Conical Bearings

Published: November 2017

Abstract
Based on the micropolar fluid models of Eringen and Christensen’s stochastic theories, the analysis of the effects of surface roughness and the squeeze film lubrication problems between conical bearings are presented. The concerned nondimensional Reynolds equation is solved with appropriate boundary conditions in dimensionless form to find the pressure distribution, which is then used to obtain the expression for load-carrying capacity, paving the way for the calculation of response time. Computed values of pressure, load capacity, and response time are displayed in graphical form. This investigation reveals that the bearing system admits an improved performance as compared with that of a bearing system working with a conventional lubricant. According to the results, the effects of transverse roughness provide an increase in the bearing characteristics as compared with the smooth bearing lubricated with micropolar fluid whereas the influences of longitudinal roughness yield a reversed trend. The quantifiable effects of rough surfaces and non-Newtonian fluids on bearing performances are more pronounced for the roughness and micropolar parameters.

OBJECTIVES:
Identifying factors associated with risk for eating disorders is important for clarifying etiology and for enhancing early detection of eating disorders in primary care. We hypothesized that autoimmune and autoinflammatory diseases would be associated with eating disorders in children and adolescents and that family history of these illnesses would be associated with eating disorders in probands.

METHODS:
In this large, nationwide, population-based cohort study of all children and adolescents born in Denmark between 1989 and 2006 and managed until 2012, Danish medical registers captured all inpatient and outpatient diagnoses of eating disorders and autoimmune and autoinflammatory diseases. The study population included 930 977 individuals (48.7% girls). Cox proportional hazards regression models and logistic regression were applied to evaluate associations.

RESULTS:
We found significantly higher hazards of eating disorders for children and adolescents with autoimmune or autoinflammatory diseases: 36% higher hazard for anorexia nervosa, 73% for bulimia nervosa, and 72% for an eating disorder not otherwise specified. The association was particularly strong in boys. Parental autoimmune or autoinflammatory disease history was associated with significantly increased odds for anorexia nervosa (odds ratio [OR] = 1.13, confidence interval [CI] = 1.01–1.25), bulimia nervosa (OR = 1.29; CI = 1.08–1.55) and for an eating disorder not otherwise specified (OR = 1.27; CI = 1.13–1.44).

CONCLUSIONS:
Autoimmune and autoinflammatory diseases are associated with increased risk for eating disorders. Ultimately, understanding the role of immune system disturbance for the etiology and pathogenesis of eating disorders could point toward novel treatment targets.

Published: November 2017

One of the important and multifaceted areas of modern Russian and international humanities is so called â€œRussian studiesâ€. The conceptual formation of the domestic Russian studies (â€œotechestvovedeniyeâ€) refers to the 1990s. In that period researchers turned to the study of Russian civilization as an integral and independent scientific object. Russian studies explore the socio-cultural, political, economic and many other aspects of â€œcivilization portraitâ€ of the country, thereby forming a multidisciplinary knowledge of the Russian different historical eras. The article is devoted to the analyses of prospects and problems of â€œRussian Studiesâ€ and â€œRussian regional studiesâ€ as disciplines in the Russian system of higher education. In addition, the authors tried to define transformations of the concept â€œRussian studiesâ€ during the past two decade. Institutionalization of Russian studies as a new research direction was at the turn of 20th and 21th centuries. It was connected with the organization of scientific centers of Russian studies and the implementation of higher education discipline â€œRussian studiesâ€ which is taught within the masterâ€™s programs. The authors concluded that objectives and educational results of â€œRussian studiesâ€ and â€œRussian regional studiesâ€ as academic disciplines are still not clearly marked, as well as not determined definitively the status of these courses and programs. Nowadays there is no bachelor or master educational programs on â€œRussian studiesâ€, and the corresponding center in the Russian State Humanitarian University trains masters in history, political science and philology.Â Keywords: Russian studies; higher education system; regional studies; multidisciplinary knowledge; international humanities; civilization approach.

Abstract

Test-taking strategies are conscious processes that respondents employ to enhance their performance on language tests. This article reports a study on test-taking strategies utilized by low and high proficiency female EFL respondents in completing multiple-choice vocabulary and structure tests. The study seeks to explore how test-taking strategies vary according to the participants’ proficiency level. Data were collected from 60 Persian EFL learners at a reputable institute on completing vocabulary and structure test items. The data were collected, categorized, and analyzed based on an adapted version of strategy questionnaire developed by Phakiti (2006). The results indicated that low-proficiency participants utilized mnemonic strategies more frequently than high-proficiency participants in completing both tests. In completing structure tests, high-proficiency participants employed mnemonic strategies more than cognitive and meta-cognitive strategies. In completing vocabulary test items, however, they drew almost equally on all three strategy types. The results also indicated that the low-proficiency participants did better in completing vocabulary test than high-proficiency participants did. Further, high proficiency participants performed better in structure tests than low proficiency participants did. The findings seem to indicate that foreign language learners rely more on mnemonic strategies than cognitive and meta-cognitive strategies due to their deficient competency in L2 knowledge. The results have implications for foreign language teachers and learners.
Key words: Test-taking strategy, cognitive and meta-cognitive strategy, mnemonic strategy, Iranian EFL learners.
Infants acquire words before concepts: A case study
Authors: Osokina Svetlana Anatolyevna 
Published: November 2017

Abstract
The purpose of the paper is to prove that for a child the system of abstract concepts grows from the “material work” with the language. Using the case study method to a particular child we prove that little children can use rather complicated abstract words without knowing the concepts of these words. Children may use such words in proper grammar forms and correct collocations but they can’t explain the meaning of the words or give wrong explanation. It makes us think that in language acquisition process the language knowledge system is being developed earlier than the conceptual system of words meaning but we must understand what language knowledge consists of in this case and what it actually is. Implications for future research include further study of language knowledge system as having its own value independently from concept system of knowledge.

Abstract

Assessment of ICT knowledge and skills is as important as gaining these knowledge and skills. There are two commonly used assessment types as (multiple-choice) Test Based Assessment (TBA) and Practice Based Assessment (PBA) and the question that which one is better still remains controversial. In this research, the focus of the study was examining these factors in relationship with the academic achievement of the students. More specifically, impact of assessing the students with TBA and PBA types on the students' academic achievement scores based on the aforementioned factors was examined. For this purpose, two study groups consisting of 243 students who were assessed with TBA and PBA in a course titled as Computing I were included in the present research. The results showed that there is a significant difference in academic achievement scores of the students and that the students who took TBA are more successful. According to the results, students are more comfortable and more confident with TBA whereas students taking PBA believe that PBA is better to measure ICT knowledge and skills. Therefore, it could be concluded that these two different assessment types are complementary once students' positive opinions, expectations and feelings are pedagogically secured.

Published: November 2017

AbstractThe study investigated the academic engagement and achievement orientation as correlates of reading culture of in-school adolescents in Enugu State, Nigeria. Using correlational survey research design, the study made use of a population of 3469 senior secondary 11 (SS11) in-school adolescents. A purposive sampling and stratified random sampling techniques were used to draw a sample of 340 in-school adolescents. Four research questions and two null hypotheses tested at 0.05 level of significance guided the study. The three instruments used for data collection were in-school adolescentsâ€™ academic engagement scale (IAES), in-school adolescentsâ€™ achievement orientation scale (IAAOS) and in-school adolescentsâ€™ reading culture scale (IARCS). Research questions 1-3 were answered using means and standard deviation whereas research questions 4 and 5 were answered using Pearson r and R-square. The hypotheses were tested using analysis of variance (ANOVA) at 0.05 level of significance. It was found that in-school adolescentsâ€™ academic engagement and achievement orientation significantly related with their reading culture. Based on the findings of the study, it was recommended among others that, the government, school administrators and educators put concerted effort to encourage students to be mastery oriented and academically engaged in order to prevent deleterious outcomes associated with poor reading culture since high academic engagement and high achievement orientation relates with positive academic outcomes.

Published: November 2017

Although the metabolic syndrome (MS) has usually been associated to adult health diseases, nowadays it also observed in overweight-obese (OW/OB) children. The aim of this study was to determine the incidence of metabolic syndrome in OW/OB children in Lleida. The study is an observational study, where 46 OW/OB children between 10-12 years old have participated. Anthropometric and MS related parameters in children population were measured in accordance with the IDFcriteria. Free movement was assessed by accelerometry. Participants that presented at least two risk factors for metabolic syndrome showed lower overall physical activity (effect size (ES): -1.0) and spent more time in sedentary behavior (ES:0.9) and less time in MVPA (ES:-1.1) than participants with only one. Having in mind this situation, we think it is essential to carry out urgent actions to prevent and treat overweight and obese children as well as to avoid suffering from MS at an early age.Â Keywords: metabolic syndrome; overweight-obese; children; accelerometry; physical activityÂ
