Published: December 2019

The flow behavior of 3-dimensional gas-solid fluidized bed reactors is investigated. Computational Fluid Dynamics (CFD) based on the Eulerianâ€”Eulerian flow model is simulated for ethylene dichloride production in an oxychlorination unit as an industrial case study. The simulated riser portion is 3.9 m in diameter and 15.5 m in height.Â The simulation is separated into 2 models; constant catalyst volume fraction and catalyst load variation. The effects of the operating parameters are studied. The ethylene molar feed fraction is varied from 0.17 to 0.3 with the constant mole ratio of hydrochloric acid to oxygen at 3.6. The result shows that the ethylene conversion gradually decreases when the ethylene mole fraction of the feed is more than 0.22. With the outlet pressure rising from 200 to 450 kPa, the ethylene conversion increases from 96.39 to 98.46%. The ethylene conversion significantly increases in the pressure range from 200 to 400 kPa and stays constant at over 400 kPa. The increase of cooling medium temperature from 320 to 420 K drives the ethylene conversion from 96.9 to 98.8% and the gas outlet temperature from 422 to 565 K. The gas feed temperature is varied from 400 to 500 K. The simulation shows that the gas feed temperature is varied from 400 to 500 K. The simulation shows that the gas outlet temperature also increases from 476 to 527 K but the ethylene conversion has a minor effect. Variation of catalyst quantity from 19,500 to 78,000 kg is carried out to study gas-solid flow behavior and transport phenomena. The simulation of 78,000 kg of catalyst shows the blowing out effect. The developed CFD model has the potential of being applied as a tool to predict the effect of the operating parameters and the gas-solid behavior in the reactor.

This study focused on comparative evaluation of the implementation of quality assurance mechanisms in educational management programme of public and private universities in South-East Geo-political zone of Nigeria. The study was guided by four research questions and four null hypotheses. The study was carried out in three private and eight public universities running educational management programme. The study adopted a survey research design. The population of the study was eleven heads of departments of the eleven universities. A questionnaire instrument constructed by the researcher was used to collect data for the study, titled, â€œQuestionnaire on comparative evaluation of the implementation of quality assurance mechanisms in educational management programme of universities in South-East of Nigeria (QCEI QAMEMPUSEN). The instrument was face-validated by three experts in the department of Educational Foundations of Ebonyi State University. The reliability of the instrument was obtained using cronbach alpha reliability coefficient, and it yielded 0.83. Mean scores of the respondents were used to answer the four research questions while t-test was used to answer the four null hypotheses at 0.05 level of significance.Â The study came up with some major findings to include, that both types of universities (public and private universities) in South-East implementation the four major mechanisms for quality assurance in educational management programme to a little extent, but the private universities seem to record better implementation of the four mechanisms compared to the public universities. The study then recommended among others that the National Universities Commission (NUC) should lay more emphasis on the public universities especially during main accreditation exercise of universities, as to reduce the gap that exists in the standard in both types of institutions.

Published: December 2019

As businesses evolve, to keep ahead of competition, so do their expectations for their employee's performance. An employee is a key element of an organization and their overall Â performance can decide the achievements of an organization or its failures. Every business has their own specific way of doing things, due to the constant change of the business environment. This changes therefore requires organization to adopt internal changes which tends to affect the performance of employees thus may enhance organisational growth and otherwise. The general objective of this research is to evaluate the effect of organizational change on employee job performance and compare it with the transformation framework articulated by some change management theorist and also to explore whether organizational change affect the job performance of employees. This study will make use of the data that was analyzed using the content analysis approach. This is because of its major dependence on the secondary source data. The result of the evaluation will provide how organisational change can be improved. There are some reasons why it is important that an organization must always affect a change process. The organization must consider that employees are very vital in carrying out a change process. Sustainable long-term success and performance of the organization depends on employees.

O foco do trabalho é o ser humano, em seu caminhar, observar e fazer-se presente na contemplação. O trabalho propõe a aproximação de pessoas anônimas, o estranhamento do comum e a representação no espaço-tempo da vida de outros. Fazer um recorte desse corpo manifesto que está em ação nas ruas e trazê-lo para o mesmo ambiente em que ele foi capturado faz com que a presença de sua imagem gere novos vínculos com o espaço urbano, tanto no plano estético como no social. Isso se dá por ser a rua um território em constante transformação — um espaço de liberdade, que deve ser consumido, explorado e manifestado. É um ambiente onde é preciso que se esteja presente para haver alguma alteração. Ele estando vazio, gera uma ausência, e é exatamente essa ausência que gera um espaço passível de apropriação. A manifestação urbana ajuda a construir esse território. A expressividade cotidiana dos transeuntes da cena urbana é captada e impressa em tamanho real para compor cenários sugestivos que definem a essência do trabalho. Essas imagens incitam as pessoas nas ruas a questionar sua presença na ausência de um corpo-não-corpo, estabelecendo vínculos simbólicos na apropriação do espaço e do tempo da vida anônima. Abrem portas para mundos perceptivos novos, criam novos olhares e ampliam o horizonte, deixando a informação de sua presença em sua ausência. Assim, essas interferências urbanas convidam o expectador a uma fuga de seu próprio corpo. A face oculta do anônimo e a iconofagia1 das imagens (ora as imagens devoram os homens e ora estes as devoram), muitas vezes simultaneamente, criam conexões entre a imagem reproduzida e a inserida no espaço urbano com seus transeuntes reais.

Authors: Abdallah B. , Kakhia M. , Shaker S. Abou 
Published: December 2019

Abstract
Na2WO4 films have been grown at 400 °C using thermal evaporation technique. Their structural properties were characterized by XRD, while their chemical composition was verified by both EDX and X-ray photoelectron spectroscopy (XPS). The evolution of crystallinity was studied as a function of film thickness that ranged from 500 nm to 3000 nm. The grain size increased with increasing film thickness. The surface morphology of the prepared films was studied using scanning electron microscope (SEM) and atomic force microscopy (AFM). It has been observed that the average transmittance of samples in the visible and near infrared range has varied from 90 % to 78 % with the film thickness. The optical band gap of the Na2WO4 films varied from 3.8 eV to 4.1 eV. The crystalline size increased with increasing thickness and showed better sensing response to gases. Thus, this study confirmed the possibility of using Na2WO4 thick films as a sensor element for detection of ethanol (C2H5OH), acetone (C3H6O) methanol (CH3OH) and ammonia hydroxide (NH4OH) vapor at room temperature, where thicker films exhibited sensing properties with a maximum sensitivity at 25 °C in air, especially for NH4OH.

Assessment of Arterial Stiffness Index Calculated from Accelerated Photoplethysmography
Authors: Murakami Tomoaki , Asai Katsunori , Kadono Yoshinori , Nishida Takeo , Nakamura Hajime , Kishima Haruhiko 
Published: December 2019

Abstract
Objective
An Arterial Stiffness Index (ASI) can be obtained by measuring finger photoplethysmogram using the SB200 pulse oximeter, giving a level between 1 and 6. However, it was unclear whether this method accurately reflected arterial stiffness. Brachial—Ankle Pulse Wave Velocity (baPWV) is an established method for the assessment of arterial stiffness, allowing us to compare baPWV and our own ASI.

Methods
We retrospectively collected data from 18 patients scheduled for neuroendovascular therapy in the Department of Neurosurgery at Osaka University Hospital between March 2016 and December 2016, for whom both baPWV and SB200 measurements were performed prior to their procedure. This allowed us to assess the relationship between the ASI and the baPWV. We defined patients with an ASI ≥ 3 on the SB200 as the progressed arterial stiffness group, while patients with a level of ≤2 were considered normal. BaPWV was compared across the two groups. We also analyzed the receiver operating characteristic curve for predicting baPWV values ≥ 1700 cm/s by the ASI measurement.

Results
The progressed arterial stiffness group showed significantly higher baPWV values (p = 0.0087). The area under the curve for the ASI was 0.84. The ASI of 3 had a sensitivity of 71.4% and a specificity of 90.1% for predicting baPWV ≥ 1700 cm/s.

Conclusion
We conclude that the non-invasive and portable SB200 device successfully measured arterial stiffness.

Authors: Pereira Telmo , Santos Fabiana , Cipriano Inês 
Published: December 2019

Abstract
Introduction
This study was aimed at evaluating the effect of a tailored exercise intervention programme in the Arterial Stiffness (AS) of old adults.

Methods
Non-randomized intervention study, enrolling 32 community dwelling old adults, aged over 65 years (mean age: 83.28 ± 8.29 years), with no prior history of major cardiovascular events. Participants were divided into two groups (intervention group—Group 2, and control group—Group 1) according to their willingness to participate in the physical training program. The exercise program included aerobic and strength components, prescribed in a personalized approach, and implemented under direct control of two experienced professionals. Aortic Pulse Wave Velocity (PWV), a measure of AS, was evaluated at baseline and 3-months after the intervention period. Clinical evaluation, anthropometric measures and blood samples were also collected in both time-points.

Results
The groups had similar clinical and demographic characteristics at baseline. After the intervention program, a significant reduction in PWV was observed only in Group 2 [F(1, 15) = 29.38; p < 0.001; η2 = 0.67]. A readjustment of the PWV age-dependent trajectory was observed, with a reduction of the absolute PWV in all age strata. A significant reduction in systolic brachial blood pressure was also depicted in Group 2 [mean difference: 12.57 mmHg; F(1, 15) = 9.46; p = 0.01; η2 = 0.39]. Parameters related to functional status, such as the handgrip strength, the self-efficacy for exercise and the activity and participation profile, were also significantly improved in Group 2.

Conclusion
Physical exercise was shown to be an effective non-pharmacological tool to positively modulate age-related decline in AS in older adults.
