Published: May 2019

Introduction Agrochemicals, also known as pesticides, are widely used in agriculture and in public health. They are organic and inorganic chemical substances with a high level of toxicity not only for the environment, but also for human health.
Objective To verify findings on labyrinthine assessment in endemic disease control agents, and to recommend the inclusion of the vestibular exam in the set of tests for pesticide-exposed populations.
Methods Descriptive, prospective, cross-sectional study with a sample comprising 15 endemic disease control agents, males, mean age of 51.6 years old (standard deviation [SD] = 5.9). All of the participants were submitted to anamnesis, otorhinolaryngological screening, and vestibular assessment.
Results Regarding the most reported complaints, dizziness (73.4%), headache (60%), and tingling in the extremities (53.4%) were observed. The findings of the vestibular exams were normal in 53.3%, while 46.7% showed peripheral vestibular disorder, of which 26.7% were of deficitary type, and 20% of the irritative type.
Conclusions: Alteration in the vestibular system was verified in 50% of the workers, with a greater prevalence in the caloric testing. Several disorders related to pesticides intoxication are scientifically known. Actions promoting knowledge and qualification of this population for the proper handling of chemicals are suggested, in addition to the elaboration and inclusion of protocols of vestibular assessment in hearing health programs for the prevention, diagnosis and treatment of vestibular disorders.
Histology of Pulmonary and Bronchiolar Disorders in Connective Tissue Diseases
Authors: Brambilla Cecilia , Rice Alexandra , Nicholson Andrew G. 
Published: May 2019

AbstractConnective tissue diseases (CTDs) are a heterogeneous group of disorders, acquired or hereditary, involving an autoimmune-mediated inflammation of connective tissues in the whole body. Lung involvement is common with CTDs, and associated with significant morbidity and mortality. Each compartment of the lung may be affected, often simultaneously, depending on the type of CTD. In addition, the lung may show pathological changes related to treatment, such as infection, drug reaction, and neoplasia. A multidisciplinary approach to diagnose these patients is essential and incorporates radiological and clinical as well as pathological data. In this review we describe the patterns of lung disease associated with common CTDs, lung disease in pediatric CTD patients, and newly recognized conditions.
Pulmonary Hypertension Associated with Connective Tissue Disease

Published: May 2019

Pulmonary hypertension (PH) is common in most forms of connective tissue disease (CTD); the prevalent type of PH depends on the particular CTD. Thus, pulmonary arterial hypertension (PAH) is dominantly associated with scleroderma, while postcapillary PH is most common in rheumatoid arthritis and lung disease-associated PH is typically found in myositis and sarcoidosis.Considerable expertise is required to identify, diagnose, and manage CTD-PH, as the primary physicians providing the majority of care for this population, rheumatologists, need a good working knowledge of CTD-PH, its rather subtle presentation, and how to access the necessary investigations to screen for and identify patients with PH. The role of the rheumatologist does not stop at diagnosis; in some conditions such as lupus, optimizing immunosuppression is key to the management of PH, and unlike simple idiopathic PAH, the natural history of CTD-PH is often punctuated by complications of the CTD rather than just events due to progression of PH or therapy-related adverse events.The aim of this article is to provide an overview of all forms of CTD-PH, and to provide an easy reference source on current best practice.

Published: May 2019

Abstract
Objective The aim of this study was to develop an in vitro biomechanical protocol for canine cementless hip arthroplasty that represents physiological gait loading (compression and torsion) and to evaluate if three alternative implant designs improve fixation compared with the traditional collarless, tapered stem in the clinically challenging case of moderate canal flare index.
Study Design Twenty-four (six/group) laboratory-prepared canine constructs were tested using a simulated gait and overload (failure) protocol. Construct stiffness, failure load/displacement and migration were measured as outcome variables.
Results Simulated gait loading did not show any significant differences between implant types for peak displacement, peak rotation, torsional stiffness, subsidence or inducible displacement. The collared and collarless stem groups were stiffer in compression compared with the collarless with a lateral bolt and short-stem groups. Increasing the loading above simulated gait showed significant reductions in compressive and torsional stiffness for all implant constructs. Despite the reductions, the short-stem group showed significantly higher stiffness compared with the other three groups.
Conclusion Peak failure loads (compressive and torsional) in this study were approximately four to seven times the simulated gait loading (430 N, 1.6 Nm) regardless of implant type and highlight the importance of limiting activity level (trotting, jumping) following hip replacement in the postoperative period and during the osseointegration of the implant.
Humboldt’sTableau Physiquerevisited
Authors: Moret Pierre , Muriel Priscilla , Jaramillo Ricardo , Dangles Olivier 
Published: May 2019

SignificanceOver the last decades, historical data have made significant contributions to assess the ecological effects of global warming. Alexander von Humboldt’sTableau Physique(1807) is by far the oldest existing dataset on altitudinal ranges of tropical mountain vegetation and represents a unique data source to assess vegetation shift in response to climate change. Yet, we show here that this exercise is not straightforward, and that partnerships between historians and ecologists are needed to tease out the intermeshing and discrepancies of past and present biodiversity records. Our findings reveal a generalized misinterpretation of Humboldt’s most iconic work; provide new estimates of vegetation shifts for the tropical alpine Andes; and profoundly renew our understanding of Humboldt’s scientific thinking, methods, and modern relevance.
Syntactic processing in sight translation by professional and trainee interpreters
Authors: Chmiel Agnieszka , Lijewska Agnieszka 
Published: May 2019

Abstract
The study examines how professional and trainee interpreters process syntax in sight translation. We asked 24 professionals and 15 trainees to sight translate sentences with subject-relative clauses and more difficult object-relative clauses while measuring translation accuracy, eye movements and translation durations. We found that trainees took longer to achieve similar translation accuracy as professionals and viewed the source text less than professionals to avoid interference, especially when reading more difficult object-relative sentences. Syntactic manipulation modulated translation and viewing times: participants took longer to translate object-relative sentences but viewed them less in order to avoid interference in target language reformulations. To the best of our knowledge, this is the first study to show that reading measures in sight translation should be analysed together with translation times to explain complex reading patterns. It also proposes a new measure, percentage of dwell time, as an index of interference avoidance.
Quantum secrecy in thermal states

Published: May 2019

Abstract
We propose to perform quantum key distribution using quantum correlations occurring within thermal states produced by low power sources such as LEDs. These correlations are exploited through the Hanbury Brown and Twiss effect. We build an optical central broadcast protocol using a superluminescent diode which allows switching between laser and thermal regimes, enabling us to provide comparable experimental key rates in both regimes. We provide a theoretical analysis and show that quantum secrecy is possible, even in high noise situations.

Abstract
Human activity has polluted freshwater ecosystems across the planet, harming biodiversity, human health, and the economy. Improving water quality depends on identifying pollutant sources in river networks, but pollutant concentrations fluctuate in time. Continuous monitoring of many points in river networks is expensive, impeding progress in developing countries where water quality is degrading fastest. In this study, we analyzed 4523 water chemistry time series of ten parameters (

We quantified the spatial stability of water chemistry across the monitoring stations using rank correlations between instantaneous concentrations and water quality metrics derived from 6-year time series (2010–2015). The strength of this rank correlation represents how well a water quality evaluation metric can be characterized with a single sampling for a given water quality parameter. Results show that a single sampling captured a mean of 88% of the spatial variability of these parameters, across ecoregions with different climate and land-use conditions. The spatial stability resulted both from high spatial variability among sites and high temporal synchrony among time series. These findings demonstrate that infrequent but spatially dense water sampling can achieve two of the major goals of water quality monitoring: identify pollutant sources and inform ideal locations for conservation and restoration interventions.
Software-Defined Optical Network (SDON), new generation networks
Authors: Leytón G V 
Published: May 2019

Abstract
At the time of establishing communications, the configuration of network resources, storage and computer systems worked independently. With the innovation and the new communication alternatives, the management was initiated so that all the parts mentioned above work together. This is how the idea of virtualization emerged, a process by which virtual versions of computers, operating systems and applications are created. For all network devices and servers to communicate with each other and function correctly there must be a centrally functioning controller, this is when a promising SDN paradigm emerges; networks defined by software considered as a promising method to rebuild the Internet architecture and improve the implementation and distribution of applications in communication networks. In addition, we will discuss how SDN networks perform their inclusion in optical networks, study these advanced architectures, in order to facilitate flexibility and resource optimization in optical transport.
Design of a WSN to determine the levels of CO and noise emitted in the parking of the CORPORACIÓN UNIVERSITARIA ANTONIO JOSÉ DE SUCRE of the city of Sincelejo-Sucre

Abstract
Wireless sensor networks (WSN) have gained great importance in recent years in different investigations and different fields, due to its wide deployment, cost and utility advantages. The constant exposure to different gases produced by combustion engines and excessive levels of noise can cause alterations in human health, especially in medium and large cities in which the vehicle fleet increases year by year. In this project a real-time contamination monitoring system is developed using wireless sensor networks for the monitoring of carbon monoxide (CO) and noise pollution in the parking of the headquarters of the Corporación Universitaria Antonio José de Sucre (CORPOSUCRE) in Sincelejo, Sucre. The data collected by the sensor nodes are sent to a computer where they can be viewed on the Serial Plotter platform. The design of the system was carried out through a site study in order to obtain the data of the variables used to get the results of the present study. The monitoring system is based on the Arduinos and XBee modules, which results in a simple design and low cost due to the characteristics of the elements used. The data obtained will allow to determine if the CO emissions and the noise levels in the parking of CORPOSUCRE exceed or not the maximum limits allowed.
Low-cost automatic device for obtaining the coefficient of static friction
Authors: Rodriguez-Arias H A 
Published: May 2019

Abstract
Considering that the coefficient of friction between materials is one of the important characteristics in the design, either by wear or by requiring friction for power transmission, and this value is usually achieved in tables and these values come out of experimentation or results with tests using devices. Furthermore, these devices are not often found in the laboratories of the universities. For this reason, it was decided to adopt one of the methods of calculation, in this case the inclined plane. This consists of finding the angle of inclination in which one material begins to slide on another, since calculating the tangent of this angle determines the coefficient of friction. To this end, a device was built, consisting of a platform that by means of a mechanism is tilted little by little, until the object under study begins to move. In addition, to exclude human error, the device has sensors and an adequate control, in such a way that the process is completely automatic. Finally, the device is based on open technology, such as Arduino, managing to build a device to obtain the coefficient of friction at low cost. Its development and the results obtained are shown in this paper.

Becoming an impediment to the integral development of the people since a greater effort must be made for their formation and communication in the daily life. In this way, that in the process of academic training for these people, who have this type of difficulty should be based on the use of new methodological strategies, generating new learning scenarios for the best class development. It will contribute in that space given that its condition of absolute deficiency of listening makes it difficult to understand a specific context, in this case in Spanish, this fundamental matter being a communication mechanism in their daily lives and in the framework of interpretive and argumentative competences. For this subject and given the condition of the student, is considered important to accompany the learning with ICT tools that allow the process to be more dynamic, from the virtual context where the student will directly interact with a learning content in a didactic way understanding in a better context this information that is taught in a classroom with a traditional methodology. Among the main advantages of using these computing resources in class is: having a homogeneous group with respect to the knowledge that corresponds to the degree they are studying and improving their lexicon ability for communication in their daily lives as they go to enrich their vocabulary and understand some words they did not understand. One of the many reasons of the distractions today, are the new technologies, the mobile devices like cellphones, videogames, audio and video players, among other things which don’t allow keep the needed focus in class.
Through the use of the developed web application it will dynamically offer a virtual space to interact with the contents of the Spanish subject to the student improving their communication and understanding the context where they live in their daily lives. Applying technological tools searching to solve this problem. The development of this research starts by generating a tool in this case a web application that, in a dynamic way, provides spaces and training activities in the basic contents of primary in Spanish, offering the student a variety of levels in those who can improve knowledge and apply the acquired notions in their training process. Additionally, you can keep track of your progress and score in the levels you are surpassing. By De la Torre S [1].

Authors: García Ramírez F , Puello Beltrán J 
Published: May 2019

Abstract
The importance of the tourism sector in Colombia has focused on aspects related to competitiveness and sustainability given the impact of tourism activity in the different destinations where it is developed. In order to maintain this advantage, it is essential to strengthen the management of sustainable tourism, optimizing the benefits for users, the destination and the local economy, while minimizing impacts on the environment. In this sense, the governmental demands oriented towards the implementation of these policies in the sector, as indicated by the Sectorial Technical Norms (NTS), specifically, the NTS-TS 002, requires the support of a technological management tool that allows the controlled development of the activities and indicators established by the regulations.
Based on this need in the tourism sector, a research project was developed based on the proposal of a management model of the NTS-TS 002 standard, was articulated with a software architecture that later will be specified in a web application to support the diagnostic process, monitoring of the indicators included in the standard and which allow accommodation and lodging establishments to be subsequently certified.

Authors: Ripoll L , Valdez L 
Published: May 2019

Abstract
One of the most used antennas today, is that of slots in waveguides. These antennas are an important type within the microwave range with various applications in electronic communications systems, radar, and satellite applications, due to its high power capacity, high efficiency, low weight, compact structure and few lateral lobes, all added together to its proven resistance to radiation, high temperatures and vibration, characteristics without which they can not be used in aerospace applications. The following lines show the design and simulation of a Slot Waveguide Array Antenna (SWAA) for satellite communications in the 30 GHz band. The antenna will be approximately 170x170 mm, constituted by 24x24 slots. It will be fed by waveguides in a lower layer connected to the radiating guides through slots. The modeling and design of the different elements that make up the power grid as T-junctions and elbows in the E and H planes were carried out.
Elastic scattering of electrons by Sr atom: a study of critical minima and spin polarization
Authors: Kumar Ashok , Abdullah M N A , Haque A K F , Singh Indu , Uddin M Alfaz 
Published: May 2019

Abstract
Within the framework of the complex optical potential, the critical minima (CM) in the differential cross sections and the spin polarization in the elastic scattering of electrons by the Sr atom are studied in the energy range E

i
= 1–1000 eV using the Dirac and Schrödinger partial wave methods. The two methods are, respectively, termed as the optical potential method of Dirac (OPMD) and optical potential method of Schrödinger (OPMS). The differential cross sections (DCSs), total cross sections (TCSs), momentum transfer cross sections (MTCSs), integral elastic cross sections (IECSs), viscosity cross sections (VCSs) and inelastic cross sections (INCSs) for e–Sr scattering are also calculated for the same energy range. In OPMD, the complex optical potential is composed of the static, exchange, polarization and absorption potentials. The OPMS potential, on the other hand, comprises the static, local exchange, polarization, spin-orbit, and absorption components. The number of CM points has been found to be respectively 7 and 5 with OPMD and OPMS methods in the DCSs of e–Sr scattering. The number of maximum spin polarization points observed is 13 and 10 for the OPMD and OPMS respectively. The energy dependence of TCS, MTCS, IECS, VCS, and INCS, studied in this work, show a non-monotonous pattern for energies beyond about 50 eV. So far as we are concerned, this is the first work for the study of CM in the DCSs of the e–Sr scattering as there are neither experimental nor theoretical studies published in the literature for the same.
Foreign Geographical Indications, Consumer Preferences, and the Domestic Market for Cheese
Authors: Slade Peter , Michler Jeffrey D. , Josephson Anna 
Published: May 2019

AbstractThe protection of geographical indications (GIs) is an important feature of modern trade agreements. In the Canada‐European Union Comprehensive Economic and Trade Agreement (CETA), Canada agreed to stronger protections for GIs of European cheeses and other food products. Under this agreement, new Canadian producers can no longer label cheese as “feta” but instead must refer to it as “imitation feta,” “feta style,” or “feta type.” We use a choice experiment to determine the effect of this agreement on Canadian cheese producers. We find that the effect of GI recognition varies depending on the terms used to label Canadian cheese and the information given to consumers. The results imply that policies that give greater latitude to food marketers will weaken the impact of GI recognition.
Tumor-Infiltrating Lymphocyte Volume Is a Better Predictor of Disease-Free Survival Than Stromal Tumor-Infiltrating Lymphocytes in Invasive Breast Carcinoma
Authors: Vaziri Fard Elmira , Ali Yasir , Wang Xiaohong I , Saluja Karan , H Covinsky Michael , Wang Lei , Zhang Songlin 
Published: May 2019

Abstract

Objectives
Tumor-infiltrating lymphocytes (TILs) have recently emerged as a prognostic factor in breast cancer. In our previous study, we proposed that tumor stroma should also be considered in the calculation of TILs and we introduced tumor infiltration lymphocyte volume (TILV) in triple-negative breast cancer.

Methods
We assessed the disease-free survival predictive value of TILV in all subtypes of invasive breast carcinoma and compared the predictive value of TILV with TILs. Differences between disease-free survival curves were determined by using the log-rank test, and Kaplan-Meier survival plots were generated for both groups.

Results
TILV was significantly correlated with disease-free survival in both invasive ductal carcinoma (P = .03) and all subtypes of invasive breast carcinoma (P = .043), whereas TILs failed to show a statistical significance.

Conclusions
Tumor-stroma ratio needs to be considered in estimation of tumor immunity, and TILV adds more predictive power to TILs.
