INDÚSTRIA 4.0: ESTUDO DA ADERÊNCIA DE SEUS PRESSUPOSTOS AO CURSO DE ENGENHARIA MECATRÔNICA DE UM INSTITUTO FEDERAL DO NORDESTE BRASILEIRO

O presente artigo trata do tema indústria 4.0 e do curso de Engenharia Mecatrônica ofertado por um Instituto Federal do nordeste brasileiro, com o objetivo de qualificar a aderência entre os conteúdos vistos ao longo do curso com os principais pressupostos da indústria 4.0. Trata-se de uma pesquisa quali-quanti descritiva, que se enquadra como estudo de caso. Após estudo bibliográfico acerca dos principais conceitos envolvendo a indústria 4.0 e seus pressupostos, selecionou-se uma gama de termos-chave que foram, por meio de exaustiva busca, encontrados nas ementas das disciplinas que, supostamente, seriam as de maior proximidade aos pressupostos estudados. Com isso, questionou-se os docentes responsáveis pelo ensino dessas disciplinas por meio de um questionário, para qualificar essa relação entre variáveis com uma visão de indivíduos especializados. A partir dos dados obtidos, concluiu-se que, Sistemas Físico-Cibernéticos, Robótica Avançada e Manufatura Aditiva Híbrida são os pressupostos da indústria 4.0 que mais se encaixam no curso, enquanto outros como Big Data e Inteligência Artificial se encaixam de forma mais escassa. Além disso, uma lista de disciplinas relacionadas foi feita com base na menção dos ministrantes e concluiu-se que a maioria delas eram optativas, o que mostra que, as tecnologias da indústria 4.0 ainda não são prioridades no curso, mas cabe aos estudantes acolhê-las pois elas serão promissoras em um futuro próximo.
Factors explaining remote work adoption in the United States

The Rural Online Initiative program at Utah State University Extension supported this quantitative study investigating the factors explaining the process of remote work adoption by organizations in the U.S. Given the potential for remote work with respect to technological advances, shifts in traditional work arrangements, and its impact on organizational/operational efficiency, there was a need to investigate how organizational characteristics and leaders' perceptions of remote work relate to its adoption. This study was guided by Rogers' theory of diffusion of innovations where research objectives were to (1) determine where organizations range in the innovation-decision process of remote work adoption, (2) categorize organizations' level of innovativeness with respect to remote work adoption over time, (3) describe how organizational characteristics relate to remote work adoption, (4) describe how the attributes of remote work relate to the likelihood of remote work adoption among organizations, and (5) describe the extent to which organizations have implemented remote work in response to COVID-19 and their favorability towards the practice.This study followed a non-experimental design with a correlational analysis, collecting cross sectional data from a sample of 1,259 organizational leaders recruited through the use of opt-in panels. Data collection was facilitated by an online survey instrument using Qualtrics software, and principles of the Tailored Design Method were used to substantiate construct and face validity.Results showed that the practice of remote work has been implemented by most organizations in the U.S. Findings indicated organizational leaders perceived the practice of remote work positively and international organizations were twice as likely to adopt remote work compared to those operating only domestically.Results also demonstrated how remote work has become a widespread workplace practice that is becoming increasingly standard across organizations in the U.S. Leaders can use the results to develop formal remote work arrangements in their organizations and should consider training existing employees and leaders in the best practices of remote work operations. Findings from this study also provide the Cooperative Extension System with insights into how it should respond to the widespread adoption of remote work with relevant, research-based educational programming in their local communities.

Asociación entre dos líneas genéticas de vacas holstein y la pérdida de gestación

Los objetivos de este estudio fueron determinar la asociación entre las líneas genéticas de Holstein Norteamericano (HNA) y Holstein Neozelandés (HNZ) y la pérdida de gestación entre los 30-60 días después de la inseminación artificial (IA), y determinar la influencia del número de parto, servicios por preñez, intervalo entre partos e intervalo parto-preñez en la pérdida de gestación dentro de cada línea genética. Se analizaron 403 lactaciones de 140 animales: 168 de 59 vacas HNA y 235 de 81 vacas HNZ. Se escogieron lactaciones de vacas preñadas (30 días después de la IA). La pérdida de gestación se calculó con el resultado de diagnóstico de gestación a los 60 días después de la IA. Se utilizó una regresión logística binaria para determinar la magnitud de la asociación. La pérdida de gestación se produjo en 104 lactaciones (25,81%): 47 (27,98%) en vacas HNA y 57 (24,26%) en vacas HNZ. Las vacas HNA tuvieron 1.21 veces más probabilidades de sufrir pérdida de gestación que las vacas HNZ (P>0,05). Las vacas HNA y HNZ multíparas tuvieron 2,52 y 2,37 veces más probabilidades de sufrir pérdida de gestación que las primíparas (P<0,05), respectivamente. Las vacas con dos o más servicios por preñez presentaron más probabilidades de sufrir pérdida de gestación (2,48 en HNA y 2,18 en HNZ; P<0,05). La línea genética de Holstein no se asoció estadísticamente con la pérdida de gestación entre los 30-60 días después de la IA. El riesgo de pérdida de gestación aumentó significativamente cuando los servicios por preñez aumentaron en ambas líneas genéticas.
Subaru and Salt Spectroscopy of Chemically Peculiar Hot Subdwarfs

Abstract The majority of hot subdwarfs lie on or close to the helium main-sequence. Many have hydrogen-rich surfaces, but a substantial fraction of the hotter subdwarfs have hydrogen-depleted or hydrogen-deficient surfaces. Amongst the former, three were known to show extraordinary overabundances of heavy elements including zirconium and lead. Using Subaru/HDS,we commenced a high-resolution survey of hydrogen-depleted subdwarfs to discover new members of the class. UVO 0825+15, was found to exhibit strong lead lines, to be an intrinsic variable in K2 field 5, and to have a relatively high space motion. Two other lead-rich subdwarfs have been found in the Subaru sample. A much wider survey is in progress using SALT/HRS. Discoveries so far include one extreme helium star similar to V652 Her, and an intermediate helium star with possible comparison to HD144941. Analyses of the hotter and more compact members of the sample are continuing.
Migration controls and counter-terrorism in Europe: a discussion of challenges and policies

This paper explores the European suspicion against the migrants and analyses the European security concerns regarding terrorist attacks. The paper shows that Europeans’ wrong perception about migrants has been created by homogenizing the category of migrants as well as politicizing the issue of migrants for electoral maneuvering. The suspicion has been grown after the 9/11 terrorist attack on America. Islamic radical organization Al-Qaeda perpetrated this attack to achieve its political agenda. This attack gave legitimacy to America and Europe to suspect everybody who is coming into their area. The studies on linking migration with terrorism show scanty evidence, but scholars have biased opinions on this. The paper explores all these issues.
Evaluation of Accuracy of Microplate Alamar Blue Assay and Proportion Method for Prompt Detection of Mycobacterium tuberculosis and Clinical Isolates of Multidrug-resistant M. tuberculosis

Background: Tuberculosis is appraised to cause the deaths of more than a billion people in the last decades. Objectives: The current study compares the performance of microplate Alamar blue assay for clinical isolates of Mycobacterium tuberculosis and multidrug-resistant tuberculosis. Microplate Alamar blue assay was performed in a central tuberculosis laboratory at Golestan University of Medical Sciences in Gorgan, Iran. Methods: In the first step, the microplate Alamar blue assay was used for the detection of 78 clinical isolates in the Golestan regional tuberculosis reference laboratory, and the results were compared with those of the proportion assay. In the second step, the microplate Alamar blue assay and the proportion assay were used for the drug-susceptibility of 35 isolates. Results: In the microplate Alamar blue assay, the sensitivity was 100 (90.97 - 100), with a specificity of 74.36 (57.87 - 86.96), positive predictive value of 79.59 (65.66 - 89.76), and negative predictive value of 100 (88.06 - 100). For the microplate Alamar blue assay with rifampin, the sensitivity was 100 (89.11 - 100), specificity was 100 (29.24 - 100), positive predictive value was 100 (89.11 - 100), and negative predictive value was 100 (29.24 - 100). For the microplate Alamar blue assay with isoniazid, the sensitivity was 84.38 (67.21 - 94.72), specificity was 66.67 (9.43 - 99.16), positive predictive value was 96.43 (81.65 - 99.91), and negative predictive value was 28.57 (3.67 - 70.96). Conclusions: We found high accuracy between the microplate Alamar blue assay with rifampin and the proportion assay. The rapid and low-cost microplate Alamar blue assay is an inexpensive and appropriate assay for the detection of rifampin-resistant tuberculosis in low-income countries.
Transitions sol-gel de colloïdes anisotropes sous champs de cisaillement, pression et ondes ultrasonores, caractérisées par diffusion de rayons x aux petits angles in-situ

The dynamical phase transition from fluid to gel state of colloidal particles submitted simultaneously to shear flow, pressure and ultrasound has been investigated during ultrafiltration process assisted by ultrasound (US). A novel ‘‘SAXS Cross-Flow US-coupled Filtration Cell’’ has been developed to monitor in-situ the colloidal organization and sol-gel transition of anisotropic clay dispersion near the membrane surface by in-situ time-resolved small-angle X-ray scattering (SAXS). Several aqueous colloidal clays have been studied: natural plate-like Na-Wyoming montmorillonite and synthetic disklike Laponite clay in the presence or absence of an added peptizer, polyphophate (Na4P2O7). Furthermore the effect of ultrasound on the rheological behavior of the suspensions has been characterized. Effects of pre-shearing and US treatment on stress levels of Laponite sample were revealed. It shows that both treatments reduce their stress levels and Laponite dispersions with peptizer (6%) are more susceptible to shearing force or ultrasonic force than those without peptizer. From the scattered intensities of colloidal particles, the volume fraction evolutions as a function of the distance from the membrane surface have been deduced for different filtration conditions and with or without ultrasound. Thanks to the in-situ structural characterization, the mechanism of US actions within the fouling layers is revealed as an additional force. US leads to different changes in the structural organization near the membrane surface: i) no layer disruption but with a localized particle agitation phenomenon (case of a denser network of particles pertaining to an anisotropic accumulation of particles – Montmorillonite and Laponite without tspp) ii) a progressive disruption of the fouling layer (case of an open structural organization of the Laponite with tspp). Mots clefs : Suspensions, Colloïdes, Anisotrope, Transition Sol-Gel, Ultrafiltration, Ultrasons, SAXS.

Consensus stability analysis for stochastic multi-agent systems with multiplicative measurement noises and Markovian switching topologies

We investigate the consensus stability for linear stochastic multi-agent systems with multiplicative noises and Markovian random graphs and investigate the asymptotic consensus in the mean square sense for the systems. To establish the consensus stability for the systems, we analysis the consensus error systems by developing general stochastic differential equation with jumps, matrix theory and algebraic graph theory, and then show that the error consensus in the mean square sense finally tending to zero as time goes on is determined by the strongly connected property of union of topologies. Finally, we provide an example to demonstrate the effectiveness of our theoretical results.
Thermotropic liquid-crystalline properties of extended viologen bis(triflimide) salts

ABSTRACT A series of extended, symmetric viologen triflimides were synthesised by the metathesis reaction of lithium triflimide with the respective viologen tosyalates in methanol. Their chemical structures were characterised by Fourier Transform Infrared, 1H and 13C Nuclear Magnetic Resonance spectroscopy and elemental analysis. Their thermotropic liquid-crystalline (LC) properties were examined by a number of experimental techniques including differential scanning calorimetry, thermogravimetric analysis, polarising optical microscopy and variable temperature X-ray diffraction. The viologen salts containing alkyl chain of two carbon and three carbon atoms were relatively low melting salts. Those of alkyl chains of four carbon and five carbon atoms formed ionic liquids at 88 and 42°C, respectively. Those of alkyl chain of 9, 10 and 11 carbon atoms were high melting salts, as high as 166°C. Those of higher alkyl chains of 16, 18 and 20 carbon atoms showed thermotropic LC phases forming SmC, SmA and an unidentified smectic (SmX) phases, and showed SmA to isotropic transitions at high temperatures. As expected, all the viologen triflimides had excellent stabilities in the temperature range of 338–365°C. Graphical Abstract
EVALUATION OF PLANT POWDERS AZADIRACTA INDICA AND ZINGIBER OFFICINALE AGAINST THE BEAN WEEVIL, CALLOSOBRUCUS MACULATUS (FAB.) (COLEOPTERA) IN STORAGE OF BEAN GRAIN

The study was carried out to investigate the efficacy of two botanical powders Azadiracta indica (A Juss) leaves and Zingiber officinale (Roscoe) rhizome in the control of Callosobrucus maculatus (Fabricius) damage on stored beans seed (Vigna unguiculata L. Walp). The two botanicals were applied at the rate of 0, 2, 4, 6 and 8 grams respectively for the control of C. maculatus, against a standard pesticide. The botanical powders were introduced into 50 g of clean beans and thoroughly mixed together by agitating the vials manually, 20 unsexed adult C. maculatus were introduced into each vial and kept under ambient conditions (27 ± 3 0 C and 80 ± 10 RH) for a period of 96 hours in July 2016. Each set of experiment was laid out in a completely randomized design comprising six treatments with each treatment having four replicates. Results from the data analyses showed that treated bean grains in storage recorded significantly higher (p<0.05) mean mortality of adult C. maculatus than the untreated controls. Batches treated with higher doses (4, 6, 8 g) had comparatively higher and significant total mortality of adult C. maculatus than those treated with smaller dosages (0 and 2 g).
Clinical Features of the Stroke Patients in Bangladesh

Original Research Article Background: Nearly three-quarters of all strokes occur in people over the age of 65.Although strokes can and do occur at any age, the risk of having a stroke more than doubles each decade after the age of 55 years. The aim of this study was to assess the clinical status of the stroke patients attended in a tertiary care hospital of Bangladesh. Methods: This descriptive cross sectional study was conducted at the department of Medicine in Sheikh Hasina Medical College and Hospital, Jamalpur, Bangladesh during the period from January 2018 to December 2018. Non randomized, purposive sampling technique was applied for this study. In total 180 stroke patients attended to the mentioned hospitaal were finalized as the sample and all the nurses engaged in the treatment procedure were associated in the study. Data was collected by using a semi structure, pre-tested and modified interviewer administered questionnaire. Statistical package for social science (SPSS) version 20.0 (Chicago) a computer programmed was used to entry and analyze the collected data. Result: Among the respondents 24.6% affected in right side, 23% left side and 20.2% both sides but 32.2 % respondents could not get it diagnosed. In this study, majority of the respondents (95%) family history of CVD was positive, and only 5% family history of CVD was negative. In total 44.3% respondents very suffering from HTN for 1-2 years, followed by 33.9%, 18.6%, and 3.3% suffered for 3-5 years, 6-10 years, and more than10 years respectively whereas 46.2% of the respondents very suffering from DM for 3-5 years, followed by 45.5% for 1-2 years, and rest 8.3% for 6-10 years. There was the association between gender and knowledge on risk factor of stroke is DM. The association is strongly significant where the p-value is 0.000 (which is less than .001). Conclusion: Stroke cases in Bangladesh have significantly increased in number over the past decades; adverse outcome from these cases are also rising due to the low number of neurologists and specialized hospitals in the country. Because stroke poses long-term economic impacts on individuals, families, and the country; study findings urge the government to put more emphasis on healthcare development by building more stroke rehabilitation units and tertiary hospitals to prevent stroke occurrence and recurrence.

Thin-Layer Chromatography Fractionation and Densitometric Determination of Residues of Diazinon and Chlorpyrifos Pesticides in Lavender and Rosemary Leaves

Lavender and rosemary are shrubs that have many medicinal uses. Like any other shrubs, they are susceptible to pest infection which needs pesticides treatment. Residues of pesticides in lavender and rosemary leaves may be hazardous to human health. The main objective of this study was to develop accurate and sensitive methods for the determination of residues of pesticides, namely, diazinon and chlorpyrifos, in lavender and rosemary leaves. Thin-layer chromatography (TLC) fractionation was applied to separate the desired pesticides to be analyzed and to determine the rate of the disappearance of these pesticides from lavender and rosemary leaves. Diazinon and chlorpyrifos were separated from extracts of leaves using silica gel 60 F254 plates. The mobile phase was formed of petroleum ether–ethanol–glacial acetic acid (9.5:0.5:0.1, v/v) and (9.0:1.0:0.1, v/v) as the developing systems for diazinon and chlorpyrifos, respectively, followed by densitometric measurement at 254 nm for both pesticides. The methods were validated over a range of 0.01–l.6 μg band−1 for diazinon and 0.04–2.0 μg band−1 for chlorpyrifos. The detection limits of diazinon and chlorpyrifos were 0.003 and 0.012 μg band−1, respectively. The safe harvest interval (pre-harvest interval; PHI), time in days between the last pesticide application to the crop and the time it can be safely harvested, was suggested to be 21 and 24 days for diazinon and chlorpyrifos, respectively. The developed TLC methods were used for sample cleanup and estimation of the studied pesticides residues in leaves extracts, in addition to the determination of the pre-harvest interval.
