Abstract: The street markets are an aggregational of commercial establishments where a variety of food products can be found, so we must consider the commercialization of these products and the hygienic conditions of these distribution places, which directly affect the quality of the food offered at these markets. This study aimed to evaluate the hygienic and sanitary conditions of the street market located in the southwest region of Bahia. Through this study, it was possible to identify that the main points that need improvement are regarding the hygiene habits of the handlers, how food storage works and the lack of water, which is one of the most critical points found during this evaluation. This study reinforces the need for supervision by the responsible agencies, so that educational actions can be implemented through courses, workshops and lectures in order to raise awareness about their managing and minimize the risks to public health. Keywords: Evaluation. Poultry Checklist. Chicken. Hygienic-sanitary. Production.
Use of Computed Tomography to Distinguish Thrombus from Pannus on a Bioprosthetic Aortic Valve
Authors: Kealhofer Jessica V. , Markowitz Jeremy S. , Nijjar Prabhjot S. 
Published: October 2019

Bioprosthetic valve thrombosis was previously considered to be a relatively rare complication of surgical or transcatheter bioprosthetic valve replacement. Although echocardiograms can reliably show the characteristic findings of prosthetic valve stenosis, differentiating between thrombus formation and pannus overgrowth as the underlying cause of prosthetic valve dysfunction can be challenging.
We present the case of a 75-year-old man who underwent transthoracic Doppler echocardiography in the presence of an elevated valvular gradient 2 years after his aortic valve had been surgically replaced with a bioprosthesis. The echocardiographic findings suggested prosthetic valve stenosis. Cardiac computed tomography, performed to distinguish between thrombus formation and pannus overgrowth, revealed hypoattenuated leaflet thickening and reduced leaflet mobility, which suggested thrombus. After the patient took oral anticoagulants for 3 months, images showed complete resolution of the previous abnormalities, thus confirming the diagnosis of bioprosthetic valve thrombosis. We found cardiac computed tomography valuable when evaluating our patient who had an elevated prosthetic valve gradient.

Infra-specific Identification of Fusarium oxysporum from Nonbanana Substrates and Its Ability to Move Hosts to Banana PlantsFusarium oxysporum has various life style, i.e. saprobe, endophyte and pathogen. Plant pathogenic F. oxysporum are divided into many forma specialis (f. sp.) depending on the host, for instance F. oxysporum f. sp. cubense (Foc), a causal agent of Panama disease of banana. The study aimed to determine the infraspecific identity of F. oxysporum from non-banana host and evaluate its ability to jump banana plants. Infraspecific identity was determined through a molecular approach using 3 specific primers to recognize TR4 race (TR4 F/R, TR4 F/R1, and FocSc-1/ FocSc-2), while the host’s transfer ability was tested on 2 banana cultivars namely cv. Ambon and Tanduk. Thirteen strain studied i.e IPBCC 88,012, IPBCC 07,528, IPBCC 07,561, IPBCC 08,562, IPBCC 08,568, IPBCC 10.674, IPBCC 14.1236, IPBCC 14.1237, IPBCC 14.1238 and IPBCC 14.1239 were TR4 Foc; IPBCC 07,338 and IPBCC 14.1242 are race Foc 4. The pathogenicity test of Foc IPBCC 88,012, 07,328, 08,561, 10,674 and 14.1236 derived from cucumbers, soil, agarwood sapwood, insect nests and quinine tree endophytes showed that these strains were able to move to banana plant. This shows that Foc may not host-specific and the infaspecific term forma specialis is therefore debatable.
Structure of the Sediment and Crust in the Northeast North China Craton from Improved Sequential H-k Stacking Method
Authors: Zhang Yi , Huang Jinli 
Published: October 2019

AbstractH-k stacking method is a standard receiver-function method to detect crustal thickness. But this method can not be applied in low-velocity sedimentary basins. To solve this problem, we propose an improved sequential H-k stacking method. The improved method needs two sequential stacks. Firstly, sediment structure is calculated using converted waves and multiples on the bottom boundary of sediments. Secondly, the sedimentary results are applied to calculate the crustal structure. Theoretical calculations and “recovery tests” indicate that the improved method can obtain accurate estimates in sedimentary basins. With the teleseismic data of North China Craton, the structure of sediments is thick in the depression and thin in the uplifted area, which is consistent with Deep Seismic Sounding results. The crust to the west of the North-South Gravity Lineament is relatively thick and has a low average Poisson ratio, whereas the east is relatively thin and has a high average Poisson ratio. This result and the structural feature from data regression imply that the eastern crust of the North China Craton has experienced wide extension, which reflect the crustal response to the severe destruction and deformation in that area compared to the western crust.

Published: October 2019

AbstractParticipatory approach is useful to clarify local interests, and improve planning activities. This paper aims to evaluate local interests change and make improvements of rural development planning activities as a response. Participatory approaches were used to make rural development planning in 2007. According to the planning activities in 2007, implementation of plans and local developing requirements were tested from local perspective in 2012. Comparing local developing requirements in 2007 and 2012, local interests changes were clarified and used to advise planning activities improvements. Wangzhuang village, Hebei province, China, was chosen as the case study. The results suggest that local preference was helpful to clarify planning goals. Conflicts between different stakeholders’ interests were mainly about planning activities related to local daily life. Local interests showed a fast changeable character in a short term. These interests generally had a stable requirement on agriculture production improvement, while changed in other aspects during local community development. Participatory approach efficiently identified local interests priority and developing requirements change with a low cost. Then advised planning activities improvements consistent supported local sustainable development. We argue that taking planning activities improvements in response to local interests change through participatory approach could efficiently stimulate rural development.
Political affiliation in post-parliamentary careers in Italian public enterprises
Authors: Quaresima Federico , Santolini Raffaella , Fiorillo Fabio 
Published: October 2019

AbstractIt has long been recognized that the presence of politicians on the boards of directors of public firms may create inefficiencies. Nevertheless, research has so far neglected the effect of political affiliation on the appointment of Members of Parliament to the boards of public firms. This article intends to fill this gap by conducting an empirical analysis on a sample of 945 deputies of the Italian Parliament elected over the period 1996–2001. Regression discontinuity estimates show that the centre-left coalition is about 25 percentage points more likely to appoint its Members of Parliament to the board of public enterprises than the centre-right coalition. Political appointments become more pronounced when the centre-left forms a governing coalition.
Assessment of ArcGIS based extraction of geoidal undulation compared to National Geospatial Intelligence Agency (NGA) model – A case study
Authors: Muhammad Sher , Tian Lide 
Published: October 2019

Abstract
Global Navigation Satellite System (GNSS) and remote sensing Digital Elevation Models (DEMs) represent earth’s surface elevation with reference to ellipsoid and orthometric heights. Proper estimation of the geoid (difference of ellipsoid and orthometric heights) is necessary before comparing data referenced to the different vertical datum. In this paper, an error in estimating EGM96 orthometric height is highlighted, verified by NGA/NASA developed model and MATLAB®. A significant error was found in the ArcGIS derived EGM96 orthometric heights range between ±6.9 meters. In addition, interpolation of low-resolution geoid data also produces significant biases depending on geographic location and the number of the interpolation data point. The bias was maximum negative in the central part of Tibetan Plateau and Himalaya. Therefore, estimation of orthometric height similar to NGA/NASA model precision is necessary for comparison of DEMs for natural resources management, 3D modelling and glaciers mass balance mainly in the mountainous regions.

Published: October 2019

Abstract
Due to the emergence of high-speed applications, demand for more bandwidth has increased exponentially in last a few years. To serve each user for his demand very fast processing and propagation of data is desired. These two requirements of high-speed communication can be fulfilled using optical fiber technology. In the same view in past many optical switch designs have emerged with their respective advantages and disadvantages. This paper proposes a wavelength division multiplexing (WDM)-based switch incorporating arrayed waveguide grating (AWG) as wavelength router and fiber delay lines (FDL) to create optical buffer. Proposed switch design is compared with recent switch design and it is found that both in terms of BER and packet loss probability the performance of proposed design is much better in comparison to earlier designs.
Enhanced Performance Analysis of 10 Gbit/s–10 GHz OFDM-Based Radio over FSO Transmission System Incorporating ODSB and OSSB Modulation Schemes
Authors: Singh Mehtab , Dhasarathan Vigneswaran 
Published: October 2019

Abstract
The exponential rise in the demand for channel bandwidth over the last few years has lead to the problem of spectrum congestion in conventional radio frequency (RF)-based wireless communication systems. Radio over free space optics (RoFSO) provides an effective solution to tackle the problem of spectrum congestion due to its many merits including license-free bandwidth, quick and low-cost installation, cost-effectiveness, and highly secure transmission links. The high-speed data transmission capabilities and immunity to electromagnetic and RF interference makes it a suitable candidate for the development of future 5 G networks. This work focuses on the designing and performance analysis of 10 Gbit/s–10 GHz orthogonal frequency division multiplexing (OFDM) based RoFSO link under the impact of different environmental effects. Also, the performance of the proposed RoFSO link has been compared for different modulation schemes viz. optical dual sideband (ODSB) and optical single sideband (OSSB). Further, we propose an enhanced detection technique deploying Square root module (SRm) at the receiver terminal for link reach enhancement under the impact of adverse weather conditions.
The Two Times of Objects: A Solution to the Problem of Time in Object-Oriented Ontology
Authors: Kleinherenbrink Arjen 
Published: October 2019

Abstract
One of the main criticisms of object-oriented ontology in its current formulation by Graham Harman is that it includes a notion of time that, upon closer inspection, renders the overall theory inconsistent. I argue that while this is indeed the case, Harman’s notion of time can be modified in a way that leaves the framework of object-oriented ontology intact. More specifically, Harman’s theory of time as a single surface tension between sensual objects and their qualities should be expanded into a theory of time as a twofold of related yet irreducible temporalities. Such a theory can already be found in Gilles Deleuze’s The Logic of Sense. I argue that much of the latter theory is already tacitly presupposed in Harman’s ontology, and show that the proposed modification successfully addresses the most salient criticisms that have been voiced at Harman’s notion of time.
Perceptions in the management of colorectal peritoneal metastases: A bi-national survey of colorectal surgeons

Published: October 2019

AbstractBackgroundThere is great variability in the uptake of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) in the management of colorectal peritoneal metastases (CRPM) in Australia and New Zealand. This study aims to provide a snapshot of perceptions among colorectal surgeons in the management of CRPM.MethodsA structured ten-question online survey was sent to all colorectal surgeons, with three questions on clinical experience and demographics, one on health economics and six on hypothetical clinical scenarios. Scores were collated and reported based on Likert scales.ResultsEighty-one respondents (36.2%) completed the survey. Most surgeons (66.7%) strongly disagreed with offering CRS and HIPEC at all hospitals. The majority (87.7%) agreed that CRS and HIPEC offered a higher survival benefit than systemic chemotherapy in pseudomyxoma peritonei (PMP), and 69.1% in CRPM (comparators: 60.5% ovarian cancer, 14.8% gastric cancer). There were mixed strategies in managing low-volume, isolated peritoneal recurrences. The majority did not recommend second-look laparoscopy, but favoured operative management of Krukenberg tumours. In the presence of incidental peritoneal metastases, only 29.6% favoured biopsy only and referring the patient to a peritoneal disease centre.ConclusionsResponse rate was relatively low. In Australia and New Zealand, colorectal surgeons see a strong role for CRS and HIPEC in the management of PMP and CRPM. The role of “second look” surgery in high-risk cases is controversial and not supported. Krukenberg tumours are viewed as surgical disease. Regular updates and collaboration with peritoneal centres may help surgeons stay abreast with latest evidence in the field.

Abstract
Constant development of novel materials and their characterization is a highly important matter nowadays. Optical contact angle measuring system is a very versatile tool among the surface characterization techniques. The main application of the technique is determination of hydrophobicity/hydrophilicity and wetting properties of materials. Current generation machines are fully automatized with a number of complements for temperature and pressure control, nanoliter drop generation, etc. Besides commenting on the current state of the art of the equipment, their capabilities and costs, this review includes some practical tips on the execution of the technique and data analysis.
Electron densities of two cyclononapeptides from invariom application
Authors: Luger Peter , Dittrich Birger 
Published: October 2019

Abstract
The nonapeptides cyclo(Val-Leu-Pro-Ile-Leu-Leu-Leu-Val-Leu) (I) and cyclo(Val-Leu-Pro-Ala-Leu-Leu-Leu-Val-Leu) (II) were identified as promising candidates for the development as potential anti-cancer drugs. We report a re-refinement of deposited single-crystal X-ray diffraction data with aspherical scattering factors from the invariom database. A subsequent evaluation of the molecular electron density distribution and of the differences in their molecular electrostatic potentials provides insight in their activities. The sequences differ only in residue 4, Ile in (I) and Ala in (II). Since the anti-tumor potency is reduced for the Ala peptide (II), the causes for the differences seen in activity between (I) and (II) were examined from a structural and from an electron density (ED) point of view. The exchange at residue 4 does not lead to significant changes in molecular geometry. Molecular Hirshfeld surfaces and electrostatic potential (ESP) isosurfaces show accumulations of intermolecular interactions in regions adjacent to the Ile/Ala residues indicating preferred interactions with a potential receptor in these regions. The concentrations of intermolecular interactions were localized on the Hirshfeld surfaces through an extended basin of ED concentration close to the Ile/Ala residues. Differences in the electrostatic potentials (ESPs) between (I) and (II) were only found at the Ile/Ala site and were very close to zero otherwise.
Applications of Laser Processing of Materials in Surface Engineering in the Industry 4.0 Stage of the Industrial Revolution
Authors: Dobrzański Leszek A. , Dobrzańska-Danikiewicz Anna D. 
Published: October 2019

AbstractThis article presents a comprehensive literature study showing contemporary industrial applications of laser processing of materials in the area of surface engineering. Laser remelting, alloying, feathering, and cladding are discussed. The results of our own research on the application of laser technologies for surface treatment, including hot work tool alloy steels, high-speed steels, magnesium and aluminum alloys, are presented. The production of porous titanium microskeletons prepared using the additive selective laser sintering (SLS) method for the production of original biological engineering materials and implants-scaffolds is presented. The laser texturing of polycrystalline silicon is also presented after texturing requiring etching in alkaline solutions and preferably also after applying antireflective coatings. The article also presents the use of SLS for the application of electrical contacts on photovoltaic cells. Identification of the critical surface of engineering technologies has been presented. Attention was paid to select 21 technologies, which were included in the group of laser processing of materials, from 500 critical technologies of surface engineering that were analyzed with our own methodology of technological foresight. In order to determine the strategic position of individual groups of critical technologies, an original set of context matrices was developed, including the dendrological matrix of technology values and the meteorological matrix of environmental impact, and the results were summarized in a sixteen-field strategy matrix for technologies. A 20-year time horizon of heuristic research was established. It has been shown that the analyzed technologies of laser processing of materials are finding wider and wider application in modern technology so that their significant development in the next two decades should be expected. It has been pointed out that laser surface technologies, because of their high development potential demonstrated by the performed foresight research, are some of the important elements of the development of the Industry 4.0 idea.
O papel do erro na construção do conhecimento matemático a partir da percepção dos professores dos Anos Iniciais

Published: October 2019

Este artigo apresenta os resultados de uma investigação junto a professores dos Anos Iniciais do Ensino Fundamental sobre as dificuldades encontradas no processo de ensino, com o objetivo de identificar e apresentar as atitudes tomadas pelos docentes frente às dificuldades de seus alunos em conteúdos relacionados à matemática, analisando a utilização do erro como ferramenta de ensino. Os dados foram obtidos por meio da aplicação de questionários destinados a professores de matemática, atuantes na etapa inicial do Ensino Fundamental, de cinco escolas municipais de Ponta Grossa-PR, os quais foram analisados de acordo com a Análise de Conteúdo. Os resultados apontam que os professores, em sua maioria, recorrem a abordagens lúdicas, não consideram o erro como possibilidade de ensino e não promovem a contextualização e a relação interdisciplinar no processo de construção do conhecimento. Conclui-se que é necessário fomentar práticas de formação docente em que os professores tenham como princípio de atuação a reflexão sobre sua prática, para viabilizar um ensino com maior abrangência, convertendo as dificuldades encontradas em ferramentas de ensino e aprendizagem.
Clubes de Ciências e contribuições para a formação docente: uma análise narrativa
Authors: Brandolt Borges Thelma Duarte , Silva Carla Melo , Lima Valderez Marina do Rosário 
Published: October 2019

Clubes de Ciências são espaços não-formais de educação científica onde são desenvolvidas atividades de investigação com base nos interesses e perguntas dos alunos. O presente trabalho tem como objetivo investigar as contribuições da monitoria em Clubes de Ciências para os licenciados em formação. Para isso, foram utilizados relatos de experiências vivenciadas por uma ex-integrante representativa do grupo, por ter composto a equipe de monitores do Clube por um período de quatro anos. Buscou-se, a partir de suas narrativas, responder a seguinte questão de pesquisa: Quais as contribuições da atuação em Clubes de Ciências para a formação docente manifestas nas narrativas de uma monitora egressa? As narrativas foram analisadas a partir do método Labov. Na perspectiva laboviana, uma narrativa é considerada completa quando é composta por seis fragmentos, sendo eles: introdução da narrativa, situação de tempo e lugar, complicação da ação da narrativa, avaliação da narrativa, resolução da complicação narrativa e coda ou fim da narrativa. Os resultados obtidos indicam que a experiência clubista proporcionou à futura professora uma experiência fora do modelo tradicional de ensino e, apesar de tratar-se de um caso específico, as contribuições ressaltadas pelo sujeito de pesquisa podem conduzir a reflexões que se estendam a outros participantes em formação inicial.
