VEGETATION MAPPING OF A COASTAL DUNE COMPLEX USING MULTISPECTRAL IMAGERY ACQUIRED FROM AN UNMANNED AERIAL SYSTEM
Authors: Suo C. , McGovern E. , Gilmer A.
Published: September 2018

Abstract. Vegetation mapping, identifying the distribution of plant species, is important for analysing vegetation dynamics, quantifying spatial patterns of vegetation evolution, analysing the effects of environment changes on vegetation, and predicting spatial patterns of species diversity. Such analysis can contribute to the development of targeted land management actions that maintain biodiversity and ecological functions. This paper represents a methodology for 3D vegetation mapping of a coastal dune complex using a multispectral camera mounted on an Unmanned Aerial System (UAS) with particular reference to the Buckroney dune complex in Co. Wicklow, Ireland. UAS, also known as Unmanned Aerial Vehicles (UAV’s) or drones, have enabled high-resolution and high-accuracy ground-based data to be gathered quickly and easily on-site. The Sequoia multispectral camera used in this study has green, red, red-edge and near infrared wavebands, and a normal RGB camera, to capture both visible and NIR images of the land surface. The workflow of 3D vegetation mapping of the study site included establishing ground control points, planning the flight mission and camera parameters, acquiring the imagery, processing the image data and performing features classification. The data processing outcomes include an orthomosiac model, a 3D surface model and multispectral images of the study site, in the Irish Transverse Mercator coordinate system, with a planimetric resolution of 0.024 m and a georeferenced Root-Mean-Square (RMS) error of 0.111 m. There were 235 sample area (1 m × 1 m) used for the accuracy assessment of the classification of the vegetation mapping. Feature classification was conducted using three different classification strategies to examine the efficiency of multispectral sensor data for vegetation mapping. Vegetation type classification accuracies ranged from 60 % to 70 %. This research illustrates the efficiency of data collection at Buckroney dune complex and the high-accuracy and high-resolution of the vegetation mapping of the site using a multispectral sensor mounted on UAS.

Published: September 2018

Abstract. New low-cost hyperspectral frame sensors have created a new perspective for remote sensing applications. In this work, we investigate some issues related to the geometric calibration of a hyperspectral frame camera based of FPI (Fabry-Pérot Interferometer), the Rikola camera. The approach proposed in paper is to study the changes in internal optical path caused by the FPI and by the splitting prism. The aim is to model the changes in the IOPs with an analytical function and also to estimate the misalignments between sensors. Several experiments were performed. The changes in position of a specific point were analasyzed to confirm that the bundle of rays is deviated. A self-calibrating bundle adjustment was performed and the Interior Orientation Parameters (IOP) of each band were estimated. The IOPs were analysed and it was concluded that a single set of symmetrical radial distortion parameters can be used for all band. Also, the estimated parameters for each image band were analysed as a function of the air gap of the FPI interferometer. It was noticed some correlation between the focal length and the air gap, and an air-gap dependent model was estimated. Thus, instead of considering an IOP set for each band or for each sensor, a single set of distortion parameters and another set of parameters that is “air-gap dependent”, was assessed. Another important issue was the determination of the misalignment angles between the two sensors, which can explain some differences in the recovered camera trajectory when performing the bundle adjustment.
ON THE CATEGORIZATION OF HIGH ACTIVITY OBJECTS USING DIFFERENTIAL ATTRIBUTE PROFILES
Authors: Boldt M. , Thiele A. , Schulz K. , Hinz S.
Published: September 2018

Abstract. Change detection represents a broad field of research being on demand for different applications (e.g. disaster management and land use / land cover monitoring). Since the detection itself only delivers information about location and date of the change event, it is limited against approaches dealing with the category, type, or class of the change objects. In contrast to classification, categorization denotes a feature-based clustering of entities (here: change objects) without using any class catalogue information. Therefore, the extraction of suitable features has to be performed leading to a clear distinction of the resulting clusters.In previous work, a change analysis workflow has been accomplished, which comprises both the detection, the categorization, and the classification of so-called high activity change objects extracted from a TerraSAR-X time series dataset. With focus on the features used in this study, the morphological differential attribute profiles (DAPs) turned out to be very promising. It was shown, that the DAP were essential for the construction of the principal components.In this paper, this circumstance is considered. Moreover, a change categorization based only on different and complementary DAP features is performed. An assessment concerning the best suitable features is given.

Abstract. ONERA is developing TERRISCOPE, a new platform to characterize the environment and the continental surfaces by optical remote sensing using manned aircrafts and UAS (Unmanned Airborne System). The objective of TERRISCOPE is to make available to the scientific community combinations of optical measurements remotely sensed with the best level state-of-the-art sensors. Different kinds of sensors have already been acquired or are still being acquired: Hyperspectral sensors (0.5–2.5 μm range), visible high resolution cameras, multispectral infrared cameras and airborne laser scanners. Each sensor is declined in two versions: one high performance for manned aircrafts and one more compact for UAS. This paper describes the whole equipment, and presents the main characteristics and performances of the carriers, the sensors and the processing chain. Possible sensors combinations on airplanes and UAS are also presented, as well as preliminary results.

Published: September 2018

Abstract. The market of imaging and non-imaging sensors offers nowadays a wide range of products, which are constantly improving and growing. Given the recent advances in the miniaturization of devices for metric survey, and the relatively cheap COTS (Commercial Off The Shelf) solutions widely available, it is therefore crucial to optimally exploit, calibrate and evaluate the performance for 3D data acquisition of the new available devices. These issues are part of the latest research addresses of different Geomatics groups, with the aim to analyze and evaluate these new sensors, in order to discover their real potentialities which are not only connected to their interesting design, low price and small dimensions.According to the final objective of the research, which is the realization of 3D metric survey of a Cultural Heritage site using different techniques and methods, one small UAV (Unmanned Aerial Vehicle) and a portable TLS (Terrestrial Laser Scanner) have been employed. The acquisition strategies and the processing methods are discussed, and the quality of the achievable results is analysed, together with an evaluation of the sensors and the outline of the best practices and use cases scenarios.
HONEY CROP ESTIMATION FROM SPACE: DETECTION OF LARGE FLOWERING EVENTS IN WESTERN AUSTRALIAN FORESTS
Authors: Campbell T. , Fearns P.
Published: September 2018

Abstract. Recent studies have shown that in the spectral space there is often a better spectral separation between leaves and flowers and even between flowers of different species than between leaves of different species. In this study we assess the ability of satellite remotely sensed data to detect the flowering of Red Gum trees (Corymbia calophylla) in Western Australia, the state’s largest annual honey crop. Spectroradiometer measurements of flowers, leaves and groundcover from Red Gum forests were subjected to ANOVA analysis, which showed that flowers are spectrally different to their environment for 92 % of the wavelengths between 350 nm and 1800 nm. A more detailed assessment, using the JM Distance calculation, showed that the spectra can be reliably separated using 10 % of the wavelengths, with peak separation between 518 nm and 557 nm. To assess the ability of satellite-borne sensors to detect the presence of flowers, the spectroradiometer data were convolved with satellite instruments’ response curves to create synthetic remotely sensed datasets on which JM Distance analysis was performed. MODIS blue bands achieved a median JM Distance of greater than 1.9 and therefore should be able to detect the presence of flowers from the environment. Further assessment showed that the shortest wavelength bands for MODIS, VIIRS and Sentinel 3 all occur where the flower spectra have lower reflectance than their natural background. A sensitivity analysis of percentage flower cover for a pixel showed that the highest sensitivity was obtained by dividing the band closest to 520 nm by the shortest wavelength band for data from these three sources. The MODIS band 10/band 8 metric was tested for its ability to detect flowers in real-world data using 15 years of qualitative honey harvest data from one apiary site as a proxy for flower density. This test was successful as, while there was some overlap between good, moderate and poor years, the poor years could be separated from the other years with nearly 80 % accuracy.
ROBOT VISION: CALIBRATION OF WIDE-ANGLE LENS CAMERAS USING COLLINEARITY CONDITION AND K-NEAREST NEIGHBOUR REGRESSION

Published: September 2018

Abstract. Visual perception is regularly used by humans and robots for navigation. By either implicitly or explicitly mapping the environment, ego-motion can be determined and a path of actions can be planned. The process of mapping and navigation are delicately intertwined; therefore, improving one can often lead to an improvement of the other. Both processes are sensitive to the interior orientation parameters of the camera system and mathematically modelling these systematic errors can often improve the precision and accuracy of the overall solution. This paper presents an automatic camera calibration method suitable for any lens, without having prior knowledge about the sensor. Statistical inference is performed to map the environment and localize the camera simultaneously. K-nearest neighbour regression is used to model the geometric distortions of the images. A normal-angle lens Nikon camera and wide-angle lens GoPro camera were calibrated using the proposed method, as well as the conventional bundle adjustment with self-calibration method (for comparison). Results showed that the mapping error was reduced from an average of 14.9 mm to 1.2 mm (i.e. a 92 % improvement) and 66.6 mm to 1.5 mm (i.e. a 98 % improvement) using the proposed method for the Nikon and GoPro cameras, respectively. In contrast, the conventional approach achieved an average 3D error of 0.9 mm (i.e. 94 % improvement) and 6 mm (i.e. 91 % improvement) for the Nikon and GoPro cameras, respectively. Thus, the proposed method performs more consistently, irrespective of the lens/sensor used: it yields results that are comparable to the conventional approach for normal-angle lens cameras, and it has the additional benefit of improving calibration results for wide-angle lens cameras.
A Profile of the “Hit Maker”: Recording the Life of Berliner, Shanghailander, and Philadelphian Gunter Hauer
Authors: Ostoyich Kevin
Published: September 2018

This article chronicles the life of retired Atlantic Records executive, Gunter Hauer. Hauer fled with his family from Nazi persecution in Berlin, Germany to Shanghai, China. There Gunter found haven with approximately 18,000 to 20,000 Jewish refugees. In 1943 he was forced by the occupying Japanese to live in a restricted zone known as the Designated Area until the end of the war. He married in Shanghai and moved with his wife to the United States. Here, he lived the proverbial “rags to riches” story as he went from being a phonograph record shipper at King Records to a distributor at Gotham Records and eventually an executive at Atlantic Records. With a can-do attitude, a gregarious demeanor, and a knack for calling the hits, Gunter put his mark on the recording industry of the Mid-Atlantic Region and beyond. He is now a sixty-year resident of Philadelphia entering his centennial year.

Enhancing Chinese Students’ Learning in an Australian 2+2 Undergraduate Engineering Program
Authors: Doe Peter Edward , Lyden Sarah , Jaikaran-Doe Seeta , Wang Xiaolin
Published: September 2018

Undergraduate engineering units (subjects) are delivered by Australian academics at two universities in China over a three-week period. Students may choose to transfer to the Australian university to complete the final two years of the Bachelor of Engineering with Honours degree (2+2 program). The aim of this study is to determine what strategies are most effective for the Australian university academics to adopt for effective delivery of engineering units at Chinese universities. A mixed methods approach was applied to in-class feedback and student surveys. Three major themes: Language, Learning and Social were identified. These themes were further explored in a quantitative survey of Chinese students newly-arrived in Australia in 2016. Successful strategies for delivering engineering units included referring questions to discussion groups; students explaining difficult concepts to other students; writing key words on the board and flash cards. The principal concern for students before they transferred to Australia was the teaching and learning style of the Australian university academics. However, English language proficiency was the major concern for students transferred to Australia. The strategy for improving Chinese students’ engagement and learning outcomes should focus on additional support both in China and Australia.
Surgical Management of Atypical Femur Fractures Associated With Bisphosphonate Therapy
Authors: Githens Michael , Garner Matthew R. , Firoozabadi Reza
Published: September 2018

Atypical femur fractures associated with long-term bisphosphonate use can be challenging injuries to manage. Not only do they have a prolonged healing time and increased rate of nonunion as compared to typical femur fractures, intraoperative complications are not infrequent and can be catastrophic. Given the pathologic nature of these fractures, a multidisciplinary approach to the patient's care is necessary. Treatment begins with medical optimization and careful surgical planning. Radiographic characteristics of the fracture and femoral osteology dictate reduction strategy, adjunctive surgical techniques, and implant choice. Intraoperative complications including malreduction, iatrogenic fracture, and fracture propagation can be avoided with thoughtful planning. The purpose of this article is to discuss the technical aspects of surgical management of atypical femur fractures. We also discuss management of intraoperative complications and treatment failure. Finally, we provide an update on recommendations for postoperative medical treatment and management of the contralateral femur.
Bundled Payment Arrangements: Keys to Success
Authors: Bosco Joseph A. , Harty Jonathan H. , Iorio Richard
Published: September 2018

The Centers for Medicare & Medicaid Services is committed to moving 50% of its fee-for-service care to value-based alternative payment models by 2018. The Comprehensive Care for Joint Replacement model is a mandatory agency program that bundles lower extremity joint arthroplasties into episodes of care that extend from the index admission to 90 days after discharge. This program, which began on April 1, 2016, includes many of the hospitals that perform total joint arthroplasties. As with other bundled payment arrangements, this model is built around seven principles that orthopaedic surgeons should be familiar with to maximize participation.
Using Patient-reported Outcomes Measurement Information System Measures to Understand the Relationship Between Improvement in Physical Function and Depressive Symptoms
Authors: Beleckas Casey M. , Guattery Jason , Chamberlain Aaron M. , Khan Taleef , Kelly Michael P. , Calfee Ryan P.
Published: September 2018

Introduction:

This investigation determined whether improved physical function and decreased pain would reduce depressive symptoms using the Patient-reported Outcomes Measurement Information System (PROMIS).

Methods:

This cohort study analyzed PROMIS Depression, Physical Function, and Pain Interference CAT scores from 3,339 patients presenting to a tertiary orthopaedic center. Patients demonstrating at least a-five point (effect size, 0.5) improvement in PROMIS Physical Function between consecutive visits were eligible for inclusion.

Results:

Patients presented, on average, with Physical Function and Pain Interference scores nearly one SD worse than population averages and Depression scores that approximated the normal population. Improved Physical Function and Pain Interference scores demonstrated no correlation with change in Depression scores (r = −0.13; r = 0.25).

Conclusion:

Substantial early improvement in PROMIS Physical Function scores is not associated with change in PROMIS Depression scores. PROMIS Depression scores likely reflect underlying mental health rather than situational depressive symptoms.

Patient Outcomes After Revision of Anatomic Total Shoulder Arthroplasty to Reverse Shoulder Arthroplasty for Rotator Cuff Failure or Component Loosening: A Matched Cohort Study
Authors: Shields Edward , Wiater J. Michael
Published: September 2018

Purpose:

To compare outcomes after conversion of anatomic total shoulder arthroplasty (aTSA) to reverse total shoulder arthroplasty (RTSA) and a matched cohort.

Methods:

Patients converted from aTSA to RTSA for rotator cuff failure or component loosening and a primary RTSA matched cohort were retrospectively identified from a prospective database. Demographics and preoperative and postoperative outcomes were obtained and compared.

Results:

Age, sex, body mass index, follow-up length, and preoperative function were similar between revision (n = 35) and primary (n = 70) groups. At final follow-up, visual analog scale pain (2.4 ± 2.8 versus 1.7 ± 2.8; P = 0.24) and American Shoulder and Elbow Surgeons (68 ± 26 versus 76 ± 24; P = 0.14) scores were similar. The revision group had worse subjective shoulder value scores (63 ± 30 versus 79 ± 21; P = 0.002), satisfaction (74% versus 90%; P = 0.03), and more complications (31% versus 13%; P = 0.02).

Conclusion:

Revision of aTSA to RTSA for component loosening or rotator cuff failure results in function comparable to primary RTSA; however, more complications, worse subjective shoulder value scores, and lower patient satisfaction should be expected.

Hemolysis Is a Diagnostic Adjuvant for Propionibacterium acnes Orthopaedic Shoulder Infections
Authors: Boyle K. Keely , Nodzo Scott R. , Wright Travis E. , Crane John K. , Duquin Thomas R.
Published: September 2018

Introduction:

The purpose of this study was to further evaluate the pathogenicity of hemolytic and nonhemolytic phenotypes of Propionibacterium acnes (P acnes) isolates from shoulders of orthopaedic patients.

Methods:

Thirty-one patient records were reviewed, which had a positive P acnes shoulder culture from joint aspiration fluid and/or intraoperative tissues for demographics, clinical course, culture, and laboratory data. Patients were categorized as definite infection, probable infection, or probable contaminant. Antibiotic resistance patterns and hemolysis characteristics were subsequently analyzed.

Results:

Hemolysis demonstrated 100% specificity with a positive predictive value of 100% and 80% sensitivity with a negative predictive value of 73% for determining definite and probable infections. Hundred percent of the patients in the hemolytic group and only 27% of patients in the nonhemolytic group were classified as infected. Presenting inflammatory markers were markedly higher in the hemolytic group. Clindamycin resistance was found in 31% of the hemolytic strains, whereas no antibiotic resistance was observed in the nonhemolytic group.

Conclusion:

Hemolytic strains of P acnes exhibit enhanced pathogenicity to their host by eliciting a more prominent systemic inflammatory response, increased antibiotic resistance, and a more challenging clinical course. Hemolysis may serve as a specific marker for assisting in diagnosing true infection with P acnes.

Published: September 2018

Introduction:

The purpose of this study was to identify objective predictors of grit, self-control, and conscientiousness in orthopaedic surgery residency applicants.

Methods:

The following attributes were assessed in 455 applicants: grit, self-control, conscientiousness, consistency of interest, perseverance of effort, and ambition. These measures were correlated with standard, objective demographics obtained during the application process.

Results:

Alpha Omega Alpha status, additional degrees, and number of publications did not predict any of the studied attributes. Grit increased with age (P < 0.001) but decreased with increasing board scores (P = 0.004). Former collegiate athletes demonstrated greater grit (P < 0.001), consistency of interest (P = 0.007), perseverance (P = 0.006), and self-control (P = 0.019). Female applicants demonstrated more grit (P = 0.044), consistency of interest (P = 0.003), and conscientiousness (P = 0.029) than males. Applicants with military experience had increased ambition (P = 0.033) and conscientiousness (P = 0.001).

Conclusion:

Overall, orthopaedics applicants possess increased grit compared with the general public, and a number of objective variables reliably predicted the studied attributes.

Published: September 2018

Introduction:

The National Surgical Quality Improvement Project (NSQIP) and the Trauma Quality Improvement Project (TQIP) collect data on geriatric hip fractures (GHFs) that could be used to generate risk-adjusted metrics for care of these patients. We examined differences between GHFs reported by our own trauma center to the NSQIP and TQIP and those vetted through an internal GHF list.

Methods:

We reviewed charts of GHFs treated between January 1 and December 31, 2015, and compared patients in an internal GHF database and/or reported to the NSQIP and/or TQIP and determined differences between databases.

Results:

We identified 89 “true” GHFs, of which 96% were identified by our institutional database, 70% by NSQIP, and 9% by the TQIP. No differences were found in outcomes and total costs. The net revenue/patient in the NSQIP database was $24,373 more than those in the institutional database.

Conclusion:

Caution should be taken when using NSQIP/TQIP databases to evaluate the care of GHFs.

Use of radiotherapy for bladder cancer: A population-based study of evolving referral and practice patterns
Authors: Wei Xuejiao , Siemens D. Robert , Mackillop William J. , Booth Christopher M.
Published: September 2018

Introduction: Definitive treatment for muscle-invasive bladder cancer includes either cystectomy or radiotherapy (RT). We describe use of RT and radiation oncology (RO) referral patterns in the contemporary era.

Methods: The Ontario Cancer Registry and linked records of treatment were used to identify all patients who received cystectomy or RT for bladder cancer from 1994–2013. Physician billing records were linked to identify RO consultation before radical treatment. Multilevel logistic regression models were used to examine patient factors and physician-level variation in referral to RO and use of RT.

Results: A total of 7461 patients underwent cystectomy or RT for bladder cancer from 1994–2013; 5574 (75%) had cystectomy and 1887 (25%) had RT. Use of RT decreased from 43% (126/289) in 1994 to 23% (112/478) in 2008 and remained stable from 2009– 2013 (23%, 507/2202). RO referral rate among all cases decreased from 46% (134/289) in 1994 to 30% (143/478) in 2008; however, the rates began to rise in the contemporary era from 31% (137/442) in 2009 to 37% (165/448) in 2013 (p=0.03). Patient factors associated with use of RT include older age, greater comorbidity, and geographic location. Surgeon-level factors associated with greater preoperative referral to RO include higher surgeon case volume and practicing in a teaching hospital.

Conclusions: One-quarter of patients treated with curative intent therapy for bladder cancer receive RT. While referral rates to RO are increasing, future data will identify the extent to which this has altered practice. Collaborative efforts promoting multidisciplinary care and RO consultation before radical treatment are warranted.
Preoperative pad usage is independently associated with failure of non-adjustable male trans-obturator slings in otherwise well-selected patients
Authors: Zemp Logan , Tong Stephen , Hoy Nathan , Rourke Keith F.
Published: September 2018

Introduction: Our objective was to determine which clinical factors are associated with failure to achieve continence after nonadjustable trans-obturator sling in otherwise well-selected men undergoing treatment for post-prostatectomy incontinence (PPI).

Methods: A retrospective review of AdVance/AdVanceTM XP male sling procedures was performed from December 2006 to May 2017. Patients with known risk factors for sling failure, including severe incontinence (>5 pads), radiation therapy, or detrusor dysfunction, were excluded. The primary outcome was failure to achieve continence, defined as ≤1 pad per day when pad use was ≥2 preoperatively (or 0 pads if preoperative pad use was 1). Covariates included patient age, Charlson comorbidity index (CCI), diabetes, obesity (body mass index [BMI] ≥35), type of prostatectomy, and number of preoperative pads. Descriptive statistics and Cox regression analysis was performed.

Results: Of 158 patients, continence was achieved in 82.3% (n=130) with a mean followup of 42.7 months. Patient-reported satisfaction was 86.7% (n=137) and the 90-day complication rate was 12% (n=19). On univariate Cox regression analysis, increasing age (p=0.02), CCI (p=0.02), and preoperative pad use (p<0.0001) were associated with sling failure, whereas obesity (p=0.95), diabetes (p=0.49), and type of prostatectomy (p=0.88) were not. On multivariate analysis, only increasing preoperative pad use remained associated with sling failure (hazard ratio [HR] 1.3; 95% confidence interval [CI] 1.1–16; p=0.008). Patients wearing >3 pads per day were more likely to experience failure (35.5% vs. 13.4%; p=0.007).

Conclusions: Increasing preoperative pad use is independently associated with an increased risk of failure after non-adjustable sling for post-prostatectomy incontinence in otherwise well-selected patients.

Mongolia is geographically in the heart of the Asian continent. In the 20th century it was part of the geopolitical “Great Game” among Russia, China, and Japan. In the 21st century, the pull of energy and mineral resource economics has changed the circumstances of the Eurasian continental paradigm and could provide the opportunity for this landlocked, Inner Asian country to find economic success, strengthen its national identity, and raise its globalimage. This paper will examine Mongolian reaction to the various Silk Roadinfluencedpolicies of its neighbors as it struggles not to be ignored in the emerging continental dynamism.

Gamification for online training of court professionalsin a Labour Court in São Paulo, Brazil (TRT-2): what can be implemented in Moodle 2.5
Authors: Oliveira Ludmilla Cavarzere , Cavalli Valquiria Trovão , Dias Álvaro Machado , Oliveira Mauri Aparecido
Published: September 2018

This paper is part of a master‘s thesis which dealt with implementation of gamification in an online course offered by Judicial School at São Paulo Regional Labour Court. The question of this paper is to review relevant literature about benefits and pitfalls of gamification in learning contexts to propose a framework for implementing gamification in Moodle 2.5. The objective of this paper is to compare the creation of a framework of an online course without game elements with its gamified version with elements that can motivate and engage people in online learning contexts, such as activity completion, restricted access, progress bar block, badges, and jeopardy-like quizzes. After implementing these features in an existing online course without gamification, the main results are that it is feasible to implement simple game mechanics in Moodle 2.5, although it takes a long time to create some of them, such as badges, and it is mandatory to have knowledge of development if the course demands Moodle documentation to create a more complex gamification block.
O trabalho docente no magistério superior em tempos de crise e de reconfiguração

Published: September 2018

O trabalho analisa os processos de intensificação e de precarização do trabalho docente que vem se concretizando no campo universitário, tendo a Universidade Federal Goiás (UFG) como objeto de estudo. Objetiva-se discutir os embates do trabalho docente frente ás políticas públicas de educação superior a partir de 1990, especificamente as políticas de expansão e de regulação do trabalho docente no magistério superior. Foram realizadas pesquisas bibliográfica, documental e empírica, sendo esta última efetivada por meio de entrevistas com gestores acadêmicos e pesquisadores de programas de pós-graduação stricto sensu de diferentes áreas de conhecimento da UFG. A pesquisa evidencia, dentre outros aspectos, que os processos de flexibilização, intensificação e precarização estão presentes na produção do trabalho acadêmico da instituição, corroborando certo alinhamento às demandas econômico-produtivas. O fato inexorável é que estão ocorrendo alterações na natureza e no caráter do trabalho docente, decorrentes, em grande parte, de demandas externas, o que tem ampliado a heteronomia na produção, organização, gestão e finalidades da universidade.
¿La lucha como escuela? Saberesy aprendizajesen procesosde lucha y organización barrial en Mendoza, Argentina, durante 1970
Authors: Baraldo Natalia
Published: September 2018

¿Podemos analizar las experiencias históricas de lucha y organización como prácticas productoras de saberes y aprendizajes? ¿Es posible, entonces, pensar la acción colectiva, en sus diversas manifestaciones, como un proceso educativo alternativo? A partir de estos interrogantes, este artículo intenta dar cuenta de la dimensión educativa de una experiencia de lucha y organización barrial que tuvo lugar en Mendoza, Argentina, tras el aluvión de enero de 1970. Identificamos los saberes y aprendizajes que fueron generándose en el proceso, así como algunos elementos de la cultura política que fueron construyéndose en la dialéctica dominación y resistencia. Aunque en este proceso los aprendizajes se producen tanto en quienes detentan el poder, como en quienes a través de su acción colectiva lo cuestionan, aquí focalizaremos en los aprendizajes de éstos últimos, basándonos en una investigación que utilizó fuentes orales y documentales, tomando como referencias téoricas las contribuciones de Maria da Glória Gohn y Edward Thompson.

Introduction: The aim of the paper was the comparative analysis of the diagnostic value of the Video Head Impulse Testing (VHIT) Ulmer I and Dix-Hallpike Test in patients with balance system disorders in out-patient practice and expertise preparation.
Material and methods: The examination was performed in 63 patients aged 20-79, including 28 women aged 20-72 and 35 men aged 23-79, divided into two groups: Group I (study group) – 33 patients with mixed cause vertigo (on the basis of the Fitzgerald-Hallpike caloric test during the VNG examination), and Group II (reference group) – 30 healthy patients. After the ENT interview and physical examination, exclusion of pathological lesions in the external acoustic meatus and middle ear, each patient was subjected to a Fitzgerald-Hallpike caloric test during VNG examination, as well as a VHIT test and Dix-Hallpike test, with the evaluation of eyeball reaction during head rotation.
Results: In the group of patients with mixed-cause vertigo (Group I), the Fitzgerald-Hallpike caloric test showed unilateral labyrinth deficiencies in 90.9% of the patients (with the average value of 41.8%) and relative directional preponderance with the average value of 19.0%, while in 9.1% of the patients, the detected values of labyrinth excitability were normal.
In the examination of patients with vertigo, benign paroxysmal positional vertigo was diagnosed in 9.1% of cases. This diagnosis was based on the positive response to the Dix-Hallpike manoeuvre and indicative of damage to the posterior semicircular canal in the VHIT test (without signs of deficiency in the VNG examination).
Conclusion: The VHIT test and Dix-Hallpike test enable quick and precise detection of benign paroxysmal positional vertigo in out-patient practice and expertise preparation.
The new generation of the biologicalengineering
materials for applications
in medical and dental implant-scaffolds

Published: September 2018

Purpose: The publication aims to find the relationship between the proliferation of surface layers
of living cells and the deposition of thin atomic layers deposition ALD coatings on the pores
internal surfaces of porous skeletons of medical and dental implant-scaffolds manufactured
with the selective laser deposition SLS additive technology using titanium and Ti6Al4V alloy.
Design/methodology/approach: The extensive review of the literature presents the
state-of-the-art in the field of regenerative medicine and tissue engineering. General ageing
of societies, increasing the incidence of oncological diseases and some transport and sports
accidents, and also the spread of tooth decay and tooth cavities in many regions of the world
has taken place nowadays. Those reasons involve resection of many tissues and organs and
the need to replace cavities, among others bones and teeth through implantation, more and
more often hybridized with tissue engineering methods.
Findings: The results of investigations of the structure and properties of skeleton microporous
materials produced from titanium and Ti6Al4V alloy powders by the method of
selective laser sintering have been presented. Particularly valuable are the original and
previously unpublished results of structural research using high-resolution transmission
electron microscope HRTEM. Particular attention has been paid to the issues of surface
engineering, in particular, the application of flat TiO2 and Al2O3 coatings applied inside
micropores using the atomic layers deposition ALD method and hydroxyapatite applied the
dip-coating sol-gel method, including advanced HRTEM research. The most important part
of the work concerns the research of nesting and proliferation of live cells of osteoblasts
the hFOB 1.19 (Human ATCC - CRL - 11372) culture line on the surface of micropores with
surfaces covered with the mentioned layers.
Research limitations/implications: The investigations reported in the paper fully
confirmed the idea of the hybrid technology of producing microporous implants and
implant-scaffolds to achieve original Authors’ biological-engineering materials. The surface
engineering issues, including both flat-layered nonorganic coatings and interactions of those
coverings with flat layers of living cells, play a crucial role.
Originality/value: Materials commonly used in implantology and the most commonly
used materials processing technologies in those applications have been described. Against
that background, the original Authors' concept of implant-scaffolds and the application of
microporous skeleton materials for this purpose have been presented.
Dissolution of carbon from coke and char
in liquid Fe-C alloys
Authors: Xing X. , Jahanshahi S. , Yang J. , Ostrovski O.
Published: September 2018

Purpose: The aim of this paper was to study dissolution of carbon from carbonaceous
materials of different origin with different morphology, microtexture and microstructure in
the liquid Fe-C alloys.
Design/methodology/approach: The dissolution of carbon from coke, char and
glassy carbon in the molten Fe-C alloy (initial carbon concentration 2.46 wt.%) at 1350°C
was measured and compared with that from graphite. The dissolution of carbon from
demineralised coke and char in the Fe-C solution was also examined to study the effect of
mineral matter on the carbon dissolution.
Findings: The concentration of carbon in the Fe-C solution dissolved from graphite was
higher than that from coke and char. Demineralisation of coke and char had a significant
effect on the carbon dissolution. The concentration of carbon dissolved from demineralised
coke and char in the Fe-C alloy approached the solubility of graphite in this alloy under the
same conditions. Results obtained in this work confirmed that ash has a strong effect on
the carbon dissolution.
Research limitations/implications: Investigations in this paper were conducted at
1350°C. At higher temperatures; (1) the degree of coke and char graphitisation increases
changing the microstructure of carbonaceous materials; (2) the ash can melt, and (3) some of
the metal oxides in the ash can be reduced by carbon to the metal phase, thereby weakening
the effect of ash on the carbon dissolution. Demineralisation of coke was incomplete; it
reached 70-80% with some effect on the carbon dissolution. The effect of ash composition
and further coke demineralisation on the carbon dissolution at higher temperature will be
investigated in the future study.
Originality/value: This study demonstrated that dissolution of carbon from coke and char
was strongly affected by ash. Reactions of dissolution of carbon from coke and char in
liquid Fe-C alloy reached a steady state within 1-2 hours. In this state, the coke/char – metal
system was far from equilibrium. The “apparent” activity which can be assigned to carbon
in the steady state is below one for graphite with significant implications for metallurgical
processes.
Chasing shadows: technology and
socioeconomic barriers versus climate
targets for iron and steel industry
Authors: Shatokha V.
Published: September 2018

Purpose: To analyse the potential of various scenarios for reduction of carbon footprint of
iron and steel sector and to reveal plausible pathways for modernisation.
Design/methodology/approach: Several scenarios have been developed in order to
assess the dynamics and extent of decarbonisation required to meet the global climate
change mitigation target. This includes deployment of the best available technologies,
increased share of secondary steel production route and deployment of innovative ironmaking
technologies with various decarbonisation extent achieved in a variable timeframe.
Findings: The window of opportunities to ensure compliance of steel sector development with
climate goal still exists though shrinks. Modernisation shall include global deployment of best
available technologies, increased share of secondary steel production and rapid deployment
of innovative technologies including carbon capture and storage. Delayed modernisation will
require much deeper decarbonisation, which will increase the total cost of mitigation. International
policies shall be put in place to ensure availability of funding and to assist technology transfer.
Short term transition strategies shall be employed as soon as possible for bridging long term
climate change mitigation strategies and current state of the iron and steel industry worldwide.
Research limitations/implications: Methodology applied takes into account the
best available technologies and some novel ironmaking methods with the potential for
commercialisation during the next decade; however, it is implied that the radically innovative
iron- and steelmaking technologies with near-zero CO2 emissions will not be mature enough
to deliver tangible impact on the sector’s carbon footprint before 2050.
Practical implications: Obtained results can be helpful for definition of the modernisation
strategies (both state-level and corporate) for the iron and steel industry.
Originality/value: Dynamics and extent of decarbonisation required to meet global
climate change mitigation targets have been revealed and the results can be valuable for
assessment of the consistency of sectoral climate strategies with global targets.

Generating a comprehensive description of cortical networks requires a large-scale, systematic approach. To that end, we have begun a pipeline project using multipatch electrophysiology, supplemented with two-photon optogenetics, to characterize connectivity and synaptic signaling between classes of neurons in adult mouse primary visual cortex (V1) and human cortex. We focus on producing results detailed enough for the generation of computational models and enabling comparison with future studies. Here, we report our examination of intralaminar connectivity within each of several classes of excitatory neurons. We find that connections are sparse but present among all excitatory cell classes and layers we sampled, and that most mouse synapses exhibited short-term depression with similar dynamics. Synaptic signaling between a subset of layer 2/3 neurons, however, exhibited facilitation. These results contribute to a body of evidence describing recurrent excitatory connectivity as a conserved feature of cortical microcircuits.
