Auditory effects of autologous fat graft for TORP stabilization in the middle ear: A cadaveric study
Authors: Aron Margaret , Landry Thomas G. , Bance Manohar 
Published: February 2018

Background Total ossicular replacement prostheses (TORP) are often used to re-establish ossicular coupling of sound in an ear lacking a stapes supra-structure. The use of TORPs, however, is associated with a 2/3 five year failure rate due to their anatomic instability over time in the middle ear. The use of autologous fat to try and stabilize TORPs may improve long-term results with this challenging ossicular reconstruction technique. Methods A cadaveric temporal bone model was developed and laser Doppler vibrometry was used to measure and record round window membrane vibration in response to sound stimulation under the following conditions: normal middle ear, middle ear filled with fat, normal middle ear with TORP prosthesis, TORP prosthesis with fat around its distal end and TORP prosthesis with fat filling the middle ear. Fourteen temporal bones were used. Results There was a significant decrease in round window membrane velocity after filling the middle ear with fat in both the normal middle ear (− 8.6 dB; p < 0.0001) and prosthesis conditions (− 13.7 dB; p < 0.0001). However, there was no significant drop in round window membrane velocity associated with using fat around the distal end of the TORP prosthesis as compared to the prosthesis without fat condition ( p > 0.05). Conclusions Autologous fat around the distal end of a TORP prosthesis may not be associated with any additional hearing loss, as demonstrated in this cadaveric model. The additional hearing loss potentially caused by using fat to completely surround the prosthesis and fill the middle ear is probably not clinically acceptable at this time, especially given the unknown way in which the fat will atrophy over time in this context.

Various methods are applied in the application of plagiarism detection to help check the similarity of a document. Jaro-Winkler Distance can measure the distance between two strings. However, this method basically depends on the position of the word. Latent Semantic Analysis emphasizes the words contained in the document regardless of its linguistic character. This study compares the results of plagiarism detection using the Jaro-Winkler Distance and the Latent Semantic Analysis method. From comparing results of Jaro-Winkler Distance method and Latent Semantic Analysis method, Jaro-Winkler Distance method is better than Latent Semantic Analysis method if using the same test data. Jaro-Winkler Distance method will give plagiarism result 100% and Latent Semantic Analysis method will give plagiarism result 97,14%.
Characterization of Self-Weight Consolidation of Fine-Grained Mine Tailings Using Moisture Sensors
Authors: Saleh-Mbemba Faustin , Aubertin Michel 
Published: February 2018

Abstract
This paper presents an experimental procedure and testing results on the consolidation of saturated tailings based on measurements made with moisture sensors. A special calibration procedure has been developed for precise volumetric water content measurements to reflect the progressive change of density and void ratio in the loose tailings. The moisture sensors’ readings are used to evaluate key parameters during self-weigh consolidation, which allow an assessment of the settlement’s rate and magnitude. The results indicate that the proposed technique can be useful to assess the tailings slurry characteristics, which significantly evolve during self-weight consolidation. The experimentally determined parameters are in the range provided by other investigations conducted on the same materials. It is also shown that pore-water pressures deduced from the volumetric water content measurements during the laboratory tests correlate well with the profiles obtained from the one-dimensional consolidation theory.

Published: February 2018

Abstract
This article investigates the wear resistance of four rock types using the rotary abrasion test. The tested rocks include argillaceous rocks (mudstone and shale) and igneous rocks (granite and andesite). The wear volume of the rock specimen was measured with various wear time, normal loads, specimen lengths, and water conditions. It was found that the wear volume of rock specimen linearly increased with wear time and normal load per unit length. The Wear Volume Index was proposed to represent the wear volume of the rocks, which was measured to be the greatest for mudstone, followed by shale, granite, and andesite for both wet and dry conditions. The presence of water significantly affects the Wear Volume Index of argillaceous rocks, which increased by 60 % for mudstone and 25 % for shale. On the other hand, the effect of water was found to be insignificant for igneous rocks such as granite and andesite.
Early Age Thermal Measurements of Soil-Cement Mixtures for Quality Control during Paving

Published: February 2018

Abstract
Cementitiously stabilized soil (i.e., soil-cement) is popular among some state departments of transportation (DOTs) for subbase and base pavement layers, particularly, states with limited supplies of quality aggregates. When constructed properly, soil-cement has proven to be a well-performing and economically beneficial product for multiple DOTs; however, there is still a growing need to better characterize soil-cement properties in the laboratory and especially during construction. This need could partly be met with thermal profile measurements of hydrating soil-cement mixtures. The overall purpose of this article is to investigate the potential use of thermal measurements as a quality control tool for compacted soil-cement mixtures used in pavement layers. A compaction device, referred to as the Plastic Mold (PM) device, was central to the approach presented in this article to perform thermal measurement and unconfined compressive strength (UCS) testing on the same specimen. Based on data presented in this article, thermal profile measurements of soil-cement mixtures are feasible and have some merit as a quality control tool. Variability analysis under laboratory conditions showed measured thermal profile results were less variable or equally as variable as UCS measurements. Under field conditions, thermal profile testing was observed to be sensitive to initial material temperature, thermal device insulation, and surrounding environment temperatures. Implementation of thermal measurements into soil-cement quality control seems to be best suited as supporting information only for cases in which UCS measured by the PM device needs more explanation.

AbstractThe ‘dilemmas’ between multilingualism in theory and English as a lingua franca in practice concern the post-Bologna European higher education as a whole. The article presents the case of Slovenia by furthering the analysis of similar quandaries present in the Slovenian (higher education) language policy. The state of affairs is addressed by acknowledging the status of Slovenian as the official language of the Republic of Slovenia, as well as the need for a greater inclusion of foreign students and teachers and for further enhancement of the quality of higher education. The results of surveys conducted among the most important stakeholders in the Slovenian higher education in October 2012, with the aim of researching the viewpoints on the use of languages of instruction in higher education, are presented. The results were analysed with a view to the expressed standpoint on language use in higher education, which led to the formation of three opinion groups within the sample of students and university teachers of the University of Ljubljana. Based on the analysis of accessible sources, discussions, opinions, surveys and interviews some recommendations on the regulation of language use in higher education in Slovenia are provided.Key words: higher education; internationalisation; language policy; Slovenian university policy.---Sažetak„Nedoumice“ između višejezičnosti u teoriji i engleskoga kao lingue france u praksi tiču se poslijebolonjskoga europskoga visokog obrazovanja u cjelini.

Abstract The aim of this research is to determine the effect of the Flipped Classroom Approach Based on the 5E Learning Cycle Model called 5ELFA on student achievement in a physics course. It also aims to determine the students’ opinions regarding this approach. This study, conducted using a mixed methods approach, involved 94 engineering students enrolled in the Physics 101 course. In the research, in which the pretest-posttest control group design was used, students were randomly assigned to experimental and control groups. While the students in the experimental group took the physics course in the Flipped Classroom Approach Based on the 5E Learning Cycle Model for 10 weeks, only the 5E learning model was used in the control group. The quantitative data were collected from a physics achievement test and the qualitative data were collected from semi-structured interviews. The results indicated that the physics achievement post-test scores of the experimental group were significantly higher than those of the control group. Interviews with experimental group volunteers revealed that the majority of students held a positive opinion of the flipped classroom approach and they believed that it had a positive impact on the physics course. Key words: 5E learning model; flipped classroom; higher education; physics education. ---SažetakCilj ovog istraživanje bio je odrediti utjecaj nastavnog pristupa obrnute učionice koji se temelji na 5E modelu ciklusa učenja, nazvan 5ELFA, na postignuća studenata u kolegiju Fizike.

AbstractThe paper aims to contribute to the knowledge about the leadership potential of talented students. The intention is to establish distinctive traits of talented students in the areas of music, art, sports, and mathematics in the following aspects of leadership: affinity for authenticity and creativity, basic personality traits, achievement motive, and emotional intelligence. The research was conducted on a convenience sample of 473 participants attending high schools for talented, using the following instruments: preconscious activity scale (PAS), Big Five Inventory (BFI), scale of achievement motive (MOP 2002) and a scale of emotional competences. The research results suggest various constellations of leadership dispositions in relation to the domain. Within the domain of sports and music, there are specific characteristics relating to public performance. Introspection and the intrapsychic plan are important characteristics of the mathematics and art domains. The domain of music and art are characterized by greater interest for innovation and diversity, while the domain of sports and mathematics revolve around “playing by set rules”. It is concluded that the leadership potential of talented students can be precisely observed and adequately supported only if it is located within the framework of individual domains.Key words: achievement motive; basic dimensions of personality; creativity; emotional intelligence. --- SažetakOvim se radom nastoje upotpuniti spoznaje o liderskom potencijalu darovitih učenika.

Medical malpractice, which is defined as “patients’ harm resulting from healthcare professionals’ improper and unethical attitude or insufficient and sloppy practice”, is strictly limited to healthcare professionals’ errors in practice. However, it should include system error analysis. In this article, a missed case of system error resulted in death is presented to remind the concept to Forensic Medicine experts and review the literature.
A 20-year-old male who underwent renal transplantation from a live donor, underwent graft nephrectomy due to acute accelerated rejection. The patient with cardiac overload findings in the postoperative period, collapsed while the patient was being sent to a special center for urgent dialysis due to lack of functional dialysis unit. In the transfer ambulance, there was no oxygen source and the patient was unable to actively ventilate. The patient died while under intensive care. In our evaluation, system error has been detected and the administration was held responsible.
The experts who are asked about the medical malpractice have to take the basic concept of "medical error" as a basis for considering the mistakes of medical applications not only from the point of view of health professionals.
Redes sociales, poder político y familia. Un análisis a partir de los Posse Talavera en Tucumán (1830-1870)
Authors: Bolsi Francisco 
Published: February 2018

Este artículo se propone analizar las redes sociales, el poder político de la élite tucumana, a partir del estudio de la familia Posse Talavera entre 1830-1870. Se utilizaron como fuentes la sección Administrativa de Hacienda, la Sección Judicial Civil, la Sección Protocolos pertenecientes al Archivo Histórico de Tucumán, información que se complementó con la producción bibliográfica sobre el período en estudio. La hipótesis que se planteo fue que la familia Posse Talavera a partir de vínculos formales –alianzas matrimoniales– e informales –relaciones de lealtad y reciprocidad– constituyó una red social y de poder que le permitió situarse en la escena de la política provincial en la década de 1860 y acumular un patrimonio significativo a partir de las actividades económicas que desarrollaron. Estos vínculos trascendieron la esfera local y regional en consonancia con la construcción del Estado Moderno en la Argentina.

Metodológicamente se empleó el enfoque histórico de la práctica pedagógica y como método algunas herramientas arqueogenealógicas. El contenido del texto se desarrolla en tres momentos: el primero analiza la emergencia de la maestrajardinera, el segundo da cuenta de la institucionalización de la enseñanza infantil como el primer nivel de instrucción y un tercer momento reescribe los discursos y prácticas para llevar a cabo la educación infantil y la formación de la maestrajardinera. Se presentan como resultados las tensiones de saberpoder que acontecieron en el marco de la pedagogía católica, los saberes para educar a los párvulos y la configuración de la cátedra de pedagogía infantil para la formación de la maestra-jardinera. Como conclusiones se exponen algunos usos de la experiencia educativa del kindergarten salesiano en el presente, recurriendo a la noción de memoria activa del saber pedagógico que permita, hacia futuro, llevar a cabo la reconceptualización de la educación inicial.
Engineered Nutshell Particles for Wellbore Strengthening

Abstract
Drilling fluid designs for wellbore strengthening have been improved through the development of engineered nutshell (ENS) products, which have replaced conventional marble for the larger particle sizes. Marble particles greater than ~400 microns are difficult to maintain in circulation due to their high tendency to grind down and settling out of suspension. Previous work has shown nut shell material to have the potential to overcome these issues. Additional laboratory results are presented which show ENS to have a low impact on mud rheology, and it is also resistant to swelling. There is some evidence for particle agglomeration but this has been found to be manageable in the field. A rigsite procedure for consistently monitoring and maintaining the size and concentration is introduced. The procedure also enables quantification of attrition rates. Two successful case studies are presented. In the first study, the introduction of ENS decreased the required material addition rates for maintenance from 60 to 17 sacks per hour. In the second case study, the corresponding decrease was from 110 to 30 sacks per hour. Furthermore, rigsite slot testing showed an improved sealing performance with ENS. These benefits are expected to become increasingly important as reservoirs become more depleted over time.
Investigation of Fracture Reopening Pressure in Wellbore Strengthening

Abstract
Lost circulation is one of the most costly drilling issues and a major contributor of non-productive time. Wellbore strengthening has been successfully applied to reduce the associated cost and increased the wellbore stability in the industry over the past two decades. It is of critical importance to accurately predict the extra drilling mud weight after wellbore strengthening. However, previous research assumed fixed boundary conditions and only considered the stress intensity factor in the calculation of fracture reopening pressure (FROP). The change of pressure boundary on the fracture surfaces was ignored, which may overestimate the FROP. This paper employed a dislocation-based fracture model to determine the FROP in wellbore strengthening. The proposed model is compared with finite element simulation. An excellent match is obtained for the fracture profile and a clear inflection point can be observed between the plugged zone and unplugged zone. We present how wellbore pressure can change the pressure boundary in the model. Thus, the FROP calculation should be modified with the consideration of fracture plug width.
Results show that the fracture plugged zone pressure can affect the fracture profile. Specifically, lower fracture plugged zone pressure results in higher FROP. Thus, better wellbore strengthening can be achieved in the depleted sections during drilling. On the other hand, the fracture plug width plays an important role in determining FROP. With a fixed fracture plug location, larger fracture plug width can lead to higher FROP. However, there exists a critical fracture plug width for the maximum FROP, which is the value predicted by the previous research. The study reveals the importance of fracture plugged zone pressure and fracture plug width for FROP in wellbore strengthening. The model is useful for the design of wellbore strengthening materials (WSM), which are critical to achieve the best wellbore strengthening effects.
