Authors: Mezouari Meriem , Fezzioui Naima , El-mir Mohamed , Claude-Alain Roulet
Published: November 2020

This study tested the effectiveness of some natural ventilation basic configurations for the thermal comfort of occupants in different local climates in Algeria. Due to the diverse Algerian climate, the study was performed during the mid-season period that includes three months of May, September, and October and the summer that includes the months of June, July, and August. The ventilation potential of the selected configurations was analysed through numerical simulation by using TRNSYS software coupled with COMIS aeraulic software. The results showed the significant contribution of natural chimney ventilation caused by a stairwell to improve occupant comfort. However; its integration requires a judicious and permanent inspection to control temperature decreases or overheating risks.

Published: November 2020

In several design calculations including the development of programs to optimize production, engineers and scientists require accurate prediction of temperature drop due to flow in oil wells. The purpose of this research is to create mathematical models to predict the effect of oil mass flow rate on temperature distribution in oil wells. A numerical mathematical model is developed to study the parameters affecting the dynamic and static temperature profiles in oil wells in production and shutting operation. The temperature distribution of the oil from the reservoir to the surface and the temperature distribution in the wall tubing of the oil well and casing, cement sheaths, and surrounding formation is studied. The natural flow of oil wells in Alwahat area located 70 Kilometres south of Marada area east of Libya in the Zaggut field called (6Q1-59) is taken as a study case. In production case, different mass flow rates in winter and summer seasons are studied. The temperature profile in the horizontal direction is estimated at different depths. The Results show that the surface temperature of crude oil increases with the rise in mass flow rate.

Published: November 2020

The objective of this research is to study flame structure and heat transfer characteristics for the premixed flame jet from the swirling chamber. In this study, LPG and air was utilized as gas fuel and oxidizer for a premixed flame. The equivalence ratios () of LPG and air were considered at 0.8, 1.0, and 1.2 under a Reynolds number Re = 4,000. The swirl flame was generated by double tangential inlets in cylindrical chamber. The diameter of chamber was fixed at D = 20 mm and the hydraulic diameter of the inlet was Dh = 5 mm. In this study, the effect of chamber geometry on flame structure was investigated by varying the chamber from H = 2.2Dh to 7.0Dh. The structures and temperature of the free flame jet was recorded with camera and measured with a thermocouple. The heat transfer rate of impinging flame jet was also measured at distance from chamber outlet to flame impingement surface varying from L = 4Dh to 10Dh. The results show that the maximum of flame temperature occurs at =1.2. Impinging flame jet for case of chamber height at H = 4.6Dh and impingement distance at L = 4Dh give the highest heat transfer for all equivalence ratios due to the reaction zone of combustion reached to approach near the heat transfer surface.

Published: November 2020

Template-assisted electrochemical deposition is a straight forward approach for the synthesis of 1D nanostructures (e.g., nanowire, nanorod, and nanobelt) with controllable morphology. This approach is suitable for mass production as it works at ambient pressure and temperature with the properties of synthesized 1D nanostructures being influenced by synthesis conditions during the electrochemical deposition process. This work aims to investigate the influence of stabilizing agent concentration and heating temperature towards the physical behavior of Nickel (Ni) nanowires synthesized via a template-assisted electrochemical deposition approach. In this research, the electrolyte bath was prepared in three different concentrations of the stabilizing agent (6 g/L, 40 g/L and 70 g/L), and the deposition bath temperature used was 30°C, 70°C, and 110°C respectively. The elemental composition was determined using Energy Dispersive X-ray (EDX) analysis to investigate the percentage of pure Ni element in the synthesized nanowires. The diameter, surface texture, and growth length of the synthesized Ni nanowires were characterized using Field Emission Scanning Electron Microscope (FESEM). X-ray diffractions (XRD) was used for crystal size and crystal orientation analysis. Additionally, the mechanical properties of Ni nanowires were extracted via molecular dynamic simulation. Growth length of Ni nanowires found to be significantly improved as the heating temperature increased, but it decreased when stabilizer agent concentration is high. The diffraction patterns for all synthesis conditions exhibited the synthesis Ni nanowires are polycrystalline as the crystalline planes with Miller indices of 111, 200, and 220. All the investigated nanowires showed ductile failure behavior, a typical behavior at larger length scales of Ni.

Published: November 2020

To overcome the lack of rural electricity in Indonesia vortex pico-hydro turbines are used as an option solution. This is due to the ability of the vortex turbine to work in low head conditions effectively. This study is conducted with comparison of curved and straight blade to obtain a more optimum turbine performance. Two methods are carried out in this study, analytical and computational method. Analytical methods are used to determine blade geometry and its performance while computational methods are used to analyse internal flow of turbine. As a result, the study concludes that hydraulic efficiency of vortex turbine in this study doesn’t affect much between straight and curved blades. The hydraulic efficiency for those blades is around 0.63. In addition, the study continued by analysing the optimum location of the blade in the basin. The results of the study show that the optimum ratio of depth and diameter of the blade is 0.33 with turbine efficiency is 0.84. Thus, the location of the blades is more important than the type of blades.

Authors: Felicity N Ncube  , Oliver Chikuta
Published: November 2020

Purpose: The purpose of the study was to assess the perceived economic impact of religious tourism in Zimbabwe. The research objectives were (1) to determine the nature of religious tourism in Zimbabwe, (2) to determine the key success factor for economically viable religious tourism in Zimbabwe, (3) to ascertain the perceived economic contribution of religious tourism, and finally (4) to propose strategies for economically sustainable religious tourism in Zimbabwe.

Methods: The research adopted a qualitative approach and was descriptive in nature. The study focused on Harare and the study population was made up of a cross-section of tourism service providers in Harare, religious leaders, and the Zimbabwe Tourism Authority. Purposive sampling was used for service providers and as well as religious leaders.

Results: The research findings revealed that there are a lot of religious tourism activities that take place in Zimbabwe, particularly Harare, and normally take the form of pilgrimages, religious conferencing, healing and deliverance nights, and worship. The perceived economic value derived includes employment creation for the locals, an increase in foreign currency generation, and an increase in sales revenue. The research findings also show that for religious tourism to be economically sustainable there is a need for government involvement, re-packaging of the product, and investment in local infrastructure.

Implications: Zimbabwe Tourism Authority and the private sector need to take the religious tourism market seriously and make deliberate efforts to harness this growing market.
A Tourism Planning of Zimbabwe for 1980-2018: A Critical Assessment
Authors: Dr Shepherd Nyaruwata
Published: November 2020

Purpose: The purpose of the study was to assess how far the government of Zimbabwe’s tourism policies and strategies have affected the development of the tourism and hospitality sector.

Methods: The study was based on a review of the literature on tourism development in Zimbabwe. A range of peer-reviewed papers, reports from the United Nations World Tourism Organization (UNWTO). reports from the Zimbabwe Tourism Authority (ZTA), and those of the Ministry of Environment, Tourism, and Hospitality Industry were consulted. The information offered a clear picture of how far the government had contributed to influencing the development of the tourism and hospitality industry during the period.

Results: The results of the study showed that for the period up to 2000 the government played only a facilitating role in the development of the sector. The results further showed that the government took a more proactive role in planning the development of the industry only when the persistent negative image of the country threatened the collapse of the sector.

Implications: It is recommended that the country effectively implements the National Tourism Master Plan and the National Tourism Sector Strategy which were launched in 2016 and 2018 respectively. A constant review of the National Tourism Sector Strategy will ensure an effective response to the global and national macro-economic, social and political changes that will occur during the plan period.

Authors: Ladislaus Fredrick Batinoluho
Published: November 2020

Purpose: The main purpose of this paper is to analyze the commercial sexual exploitation of children in the tourism industry in Tanzania and to propose mitigation measures.

Methods: This study was based on the desk review of published materials. Critical analysis of commercial sex exploitation of children in the Tourism (CSECT) industry in Tanzania was conducted.

Results: According to the findings, children in Tanzania are involved in commercial sex trade with tourists and residents. This perception was also supported by the studies which were conducted by End Child Prostitution and Trafficking International (ECPAT International) in Tanzania in 2013 and in Kenya, Zambia, and South Africa in 2015.

Implications: The problem of commercial sex exploitation of children in Tourism is aggravated by poverty and the trafficking of children for child labor engagement. The study serves as an early wake-up call for the policymakers in Tanzania. The study recommends prevention, protection, prosecution, policy, and mobilize coordinated national action to end the problem.
Developing a Model for Packaging and Popularizing Township Tourism in Zimbabwe
Authors: Precious Mazhande  , Patrick Walter Mamimine
Published: November 2020

Purpose: There is tremendous potential for vibrant township tourism in Zimbabwe. The country boasts an abundance of township tourism resources such as monuments of colonial history, administrative centers, informal sector activities, co-existence of traditional and modern cuisine, art and craft centers, community markets, iconic personalities and buildings, and others. Despite this rich heritage of tourism resources, township tourism has failed to attract a critical mass of clients to make it viable thereby depriving the country of potential revenue of this form of alternative tourism.  Keeping this in mind, the main objective of the study was to develop a model for packaging and popularising township tourism in Zimbabwe.

Method: The study adopted a qualitative methodology. Data were collected from Tour operators, residents, and Zimbabwe Tourism Authority through participant observations and in-depth interviews. Data were analyzed using a thematic approach.

Results:  The study revealed key challenges to the growth of township tourism being lack of finance, lack of support from authorities, illegal operators, and limited access to markets, stringent operational laws, and poor understanding of the concept. Furthermore, tour operators and residents were of the view that information should be disseminated through publicity associations, using brochures and travel shows to aid in popularising township tourism. Respondents highlighted the need for educating all stakeholders on township tourism and creating mutual relationships.

Implications: Recommendations included stakeholder involvement and tour operators’ in-depth knowledge of iconic tourism resources in the township. It further recommends a strategic partnership with international tour operators offering township tourism.
The Effect of Governance on International Trade and the Mediating Role of Business Regulations
Authors: Khan Shahedul Alam
Published: November 2020

The purpose of the study is to investigate the mediating role of business regulations in between the relationship of governance and international trade. Data were collected from 181 countries and the partial least squares structural equation model (PLS-SEM) was used to test the hypotheses. It was found that the business regulations practiced by a country significantly influence its international trade, but the governance of the country has a significant indirect influence on its international trade. A full mediation was evident from the results, where the indirect effect of governance on international trade was observed to be fully mediated by business regulations. The study will contribute to guiding governments and regulatory bodies to improve governance and business regulatory environment to facilitate international trade.
Legal and Policy Regulations of Performance Requirements for Foreign Investors in Bangladesh
Authors: Hossain Mohammad Belayet , Yeon Asmah Laili Bt , Aziz Ahmad Shamsul Bin Abd.
Published: November 2020

The multinational enterprises (MNEs) have a common intention to maximizing their capital investment to gain more profit. In doing so, sometimes they behave irresponsibly towards the host countries, even do not hesitate to bypass the laws of the country. In relation to performance requirements for foreign investors, the host country like Bangladesh may have specific laws or policies; but due to the desire to attract more FDI and pressure from the MNEs, the government may be reluctant to impose various requirements or refrain from enforcing them. This paper will discuss the negative impact of FDI in Bangladesh due to lack of performance requirement provisions> It will also highlight the significance of enacting such provisions into the FDI laws. This paper will address one major question: why the foreign investors should be required to fulfill performance requirements during their entry in Bangladesh? In this study, six respondents were interviewed for expert opinions. The findings of this study show that the existing laws and policies of Bangladesh significantly lack performance requirement provisions. In this relation, recommendations have been provided for consideration by the government.

Authors: Jørgensen Tanja Schjødt , Skougaard Marie , Hansen Rebekka Lund , Ballegaard Christine , Mease Philip , Strand Vibeke , Dreyer Lene , Kristensen Lars Erik
Published: November 2020

Objective.

The objective of this population-based cohort study was to investigate the association between fatigue with disease activity and drug survival in patients with psoriatic arthritis (PsA) receiving their first tumor necrosis factor inhibitor (TNFi).

Methods.

Data on patient characteristics, disease activity, and drug survival were obtained from the DANBIO database on all patients with PsA from 2006 through 2015. Information on comorbidities was obtained through linkage with the Danish National Patient Registry.

Results.

A total of 880 patients were eligible for analyses. Patients with upper median fatigue scores had statistically significant higher disease activity measures (Disease Activity Score in 28 joints based on C-reactive protein), pain, and Health Assessment Questionnaire (HAQ) scores; tender joint counts; comorbidities (Charlson Comorbidity Index ≥ 2); and current smoking status at baseline compared to patients with lower median fatigue scores (P < 0.05). In the upper median fatigue group, fewer patients achieved American College of Rheumatology (ACR) responses and improvements in visual analog scale (VAS) fatigue compared to patients in the lower median fatigue group. Kaplan-Meier curves showed shorter drug survival in patients in the upper median fatigue group compared with the lower median fatigue group at 6-month follow-up.

Conclusion.

Fatigue remains a dominating symptom after TNFi treatment, and is associated with higher baseline disease activity, pain, and HAQ scores; more comorbidities; and increased risk of TNFi treatment discontinuation in a cohort of Danish patients with PsA. The agreement between ACR and VAS fatigue responses is weak to moderate, suggesting heterogeneity between experienced fatigue and joint inflammation.

Authors: Ogdie Alexis , Liu Mei , Glynn Meghan , Emeanuru Kelechi , Harrold Leslie R. , Richter Sven , Guerette Benoit , Mease Philip J.
Published: November 2020

Objective

Therapeutic response was evaluated among new apremilast, methotrexate (MTX), or biologic disease-modifying antirheumatic drug (bDMARD) initiators with oligoarticular psoriatic arthritis (PsA).

Methods

Patients with oligoarticular PsA in the Corrona PsA/Spondyloarthritis Registry initiating treatment with apremilast, MTX, or bDMARD, and completing 6-month follow-up were included.

Results

In total, 150 patients initiated monotherapy (apremilast: n = 34; MTX: n = 15; bDMARD: n = 101). Apremilast initiators had higher baseline disease activity than MTX initiators. At follow-up, apremilast initiators experienced numerically greater disease activity improvements than MTX initiators and similar improvements to bDMARD initiators.

Conclusion

Findings suggest apremilast monotherapy is an effective option for patients with oligoarticular PsA.

Authors: Charlton Rachel A. , Green Amelia , Shaddick Gavin , Snowball Julia , Nightingale Alison , Tillett William , Smith Catherine , McHugh Neil J.
Published: November 2020

Objective.

To determine the risk of a diagnosis of osteoarthritis (OA) in patients with psoriatic arthritis (PsA) compared to patients with psoriasis and a general population cohort.

Methods.

Incident PsA patients aged 18–89 years at diagnosis were identified from the United Kingdom Clinical Practice Research Datalink between 1998 and 2014. All patients with PsA were matched to 2 cohorts of patients, both at a 1:4 ratio. The first cohort included patients with psoriasis (and no PsA) and the second was a general population cohort (with no psoriasis or PsA). The baseline prevalence of OA was calculated for each study cohort. The incidence of OA was calculated, and adjusted relative risks (RRadj) were calculated using conditional Poisson regression.

Results.

We identified 6783 incident PsA patients. The baseline prevalence of OA ranged from 22.1% (95% CI 21.1–23.1) in the PsA cohort to 12.6% (95% CI 12.2–13.0) and 11.0% (95% CI 10.6–11.3) in the psoriasis and general population cohorts, respectively. The incidence of OA was significantly higher in the PsA cohort compared to the psoriasis and general population cohorts after adjusting for BMI (RRadj 1.68, 95% CI 1.46–1.93, and RRadj 1.86, 95% CI 1.62–2.14, respectively).

Conclusion.

An increased risk of OA was observed in patients with PsA compared to patients with psoriasis alone and those in the general population. Further work is needed to determine whether this reflects a true increase in OA risk or misdiagnosed PsA, and the extent to which it can be explained by differences in the opportunity for OA diagnosis between cohorts.

Authors: Rathbun Alan M. , England Bryant R. , Mikuls Ted R. , Ryan Alice S. , Barton Jennifer L. , Shardell Michelle D. , Hochberg Marc C.
Published: November 2020

Objective.

Depression is common in patients with rheumatoid arthritis (RA), exacerbates disease activity, and may decrease response to first-line disease-modifying antirheumatic drugs. This study aimed to determine if depression affects disease activity among veterans with early RA prescribed methotrexate (MTX).

Methods.

Participants included veterans enrolled in the Veterans Affairs Rheumatoid Arthritis (VARA) registry with early RA (onset < 2 yrs) prescribed MTX. Depression was assessed at enrollment using the International Classification of Diseases, 9th revision codes (296.2–296.39, 300.4, 311). Disease activity was measured using the Disease Activity Score in 28 joints (DAS28) and other core measures of RA disease activity. Propensity score weights were used to adjust depressed (n = 48) and nondepressed (n = 220) patients on baseline confounders within imputed datasets. Weighted estimating equations were used to assess standardized mean differences in disease activity between depressed and nondepressed patients at 6-month, 1-year, and 2-year follow-ups.

Results.

The analytic sample was composed of 268 veterans with early RA prescribed MTX who were predominantly male (n = 239, 89.2%) and older (62.7 yrs, SD 10.6) than patients with RA in the general population. Adjusted estimates indicated that depression was associated with significantly higher DAS28 at 6 months (β 0.35, 95% CI 0.01–0.68) but not at the 1- or 2-year follow-up. Also, depression was associated with significantly worse pain at 6 months (β 0.39, 95% CI 0.04–0.73) and 1 year (β 0.40, 95% CI 0.04–0.75).

Conclusion.

In early RA, depression is associated with greater short-term disease activity during MTX treatment, as well as more persistent and severe pain.

Published: November 2020

Objective.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. The American College of Rheumatology (ACR) 1997, Systemic Lupus International Collaborating Clinics (SLICC) 2012, and European League Against Rheumatism (EULAR)/ACR 2019 SLE classification criteria are formed based on data mainly from adult patients. We aimed to test the performances of the SLE classification criteria among pediatric patients with SLE.

Methods.

Pediatric patients with SLE (n = 262; 80.9% female) were included from 3 different centers in Turkey. As controls, 174 children (60.9% female) with other diseases who had ANA (antinuclear antibody) test results were included. The gold standard for SLE diagnosis was expert opinion.

Results.

The sensitivities of the ACR 1997, SLICC 2012, and EULAR/ACR 2019 criteria were 68.7%, 95.4%, and 91.6%, respectively. The specificities of the ACR 1997, SLICC 2012, and EULAR/ACR 2019 criteria were 94.8%, 89.7%, and 88.5%, respectively. Eighteen patients with SLE met the SLICC 2012 but not the EULAR/ACR 2019 criteria. Among these, hematologic involvement was prominent (n = 13; 72.2%). Eight patients with SLE fulfilled the EULAR/ACR 2019 but not the SLICC 2012 criteria. Among these, joint involvement was prominent (n = 6; 75%).

Conclusion.

To our knowledge, this is the largest cohort study of pediatric SLE to test the performances of all 3 classification criteria. The SLICC 2012 criteria yielded the best sensitivity, whereas the ACR 1997 criteria had the best specificity. SLICC 2012 criteria performed better than EULAR/ACR 2019 criteria. Separation of different hematological manifestations in the SLICC 2012 criteria might have contributed to the higher performance of this criteria set.

Published: November 2020

Malaria caused by Plasmodium falciparum continues to be a major public health problem especially in tropical and sub-tropical regions of the world. Considering the growing resistance of parasites to anti-malarial drugs and of vector mosquitoes to insecticides, there is no doubt that the effective vaccine is the most awaiting tool to reduce the risk of malaria. Our synthetic studies have shown that a loop region (AD22 = 256ASEFYNSENKTYDLDFKTPNND277) of Plsmodium falciparum enolase has antigenic reactivity against patients’ sera and AD22 can produce inhibitory antibodies against in vitro parasite growth. In this paper, we will briefly present our ongoing research of malaria vaccine development and related model studies.

A case of cavernous carotid aneurysm diagnosed when diplopia developed after endoscopic sinus surgery
Authors: Tei M. , Mori E. , Kojima H. , Otori N.
Published: November 2020

Background: Visual complications of endoscopic sinus surgery usually occur during or immediately after the surgery. We report a case of cavernous carotid aneurysm which developed and gradually worsened after endoscopic sinus surgery was performed. Case presentation: A 63-year-old woman with chronic rhinosinusitis resistant to conservative treatment underwent endoscopic sinus surgery. Despite the surgery being successful and without complications, diplopia developed 2 weeks later. Intracranial ima- ging revealed a giant cavernous carotid aneurysm as a likely cause of the diplopia. The patient underwent endovascular stenting treatment, and the diplopia was consequently reduced. Conclusions: We experienced a rare case of cavernous carotid aneurysm which started to develop 2 weeks after endoscopic sinus surgery. Possible causes of the aneurysm in this patient are an indirect effect of surgery, such as perioperative hypertension, and bacterial sinusitis.

Machine Tool 4.0 in the Era of Digital Manufacturing
Authors: Mourtzis Dimitris
Published: November 2020

Under the Industry 4.0 framework, a plethora of digital technologies and techniques has been introduced in the Manufacturing domain. Machine tools must become more intelligent, in order to create a network of fully connected machines. By extension, this will lead to the creation of the Industrial Internet of Things (IIoT). Although these technologies provide for increased functionality of the manufacturing equipment, there are certain issues/implications, refraining engineers from integrating such technologies in the production. Therefore, in this paper, the results of a systematic literature review are presented and discussed, including the horizontal and vertical integration of such digital technologies. The contribution of this paper extends to the recognition of the opportunities emerging as well as the identified implications from a practical implementation point of view.

Published: November 2020

Vertically-aligned nitrogen-doped carbon nanotubes (v-N-CNTs) were synthesized \textit{via} the chemical vapour deposition (CVD) technique. 1-ferrocenylmethyl(2-methylimidazole) was employed as the source of the Fe catalyst and was dissolved in different ratios of acetonitrile/benzophenone feedstock which served as both the carbon, nitrogen, and oxygen sources. The morphological difference in N-CNTs was as a result of increased oxygen concentration in the reaction mix and not due to water vapour formation as observed in the oxygen-free experiment, indicating specifically, the impact of oxygen. Raman and X-ray photoelectron spectroscopy (XPS) revealed surface defects and grafting of oxygen functional groups on the sidewall of N-CNTs. The FTIR data showed little or no effect as oxygen concentration increases. XPS analysis detected the type of nitrogen species (\textit{i.e.} pyridinic, pyrrolic, graphitic, or molecular nitrogen forms) incorporated in the N-CNT samples. Pyrrolic nitrogen was dominant and increased (from 8.6 to 11.8 at.\%) as oxygen concentration increases in the reaction precursor. An increase in N content was observed with the introduction of a lower concentration of oxygen, followed by a gradual decrease at higher oxygen concentration. Our result suggested that effective control of the reactant mixtures can manipulate the morphology of N-CNTs.

The effective prompt response function full width at half maximum, PRF FWHM of 637 ps (obtained from the prompt gamma pairs of 477 keV and 700 keV associated with the yrast 2+ state in 206Po), and 1007 ps (obtained from the Compton gamma pairs of 189 keV and 237 keV associated with the 192Os(18O,16O)194Os 2 neutron transfer reaction) were used in fitting the time difference spectra obtained from the gamma coincident pairsof 206 keV and 374 keV in a symmetrised LaBr3(Ce) associated with the gamma transitions in 192Os, using the Half-life program. The values of half-life measured by fitting these PRF FWHM of 637 ps and 1007 ps separately show an excellent agreement of 282(16) ps and 272(21) ps, respectively, which correspond to the global half-life value of 282(4) ps for the 192Os. The mean value of 277(12) ps from these two measurements was used in calculating the B(E2; IL ->IL-2) of 4233(114) e2fm4, which is equivalent to be 81(19) W.u.

Published: November 2020

The process of extracting clinical images, for instance, heart images from cameras is full of noises and complexities. As such, the general expenditure for processing these images like resources and time is significantly high, mostly for complex and large amounts of data. In that case, this research contribution utilizes the machine vision-centred method to effectively address these issues. The method significantly incorporates four essential stages with various forms of algorithms to handle the clinical heart images. In the first stage, the smoothing algorithm is utilized to minimize some form of noise. In the second stage, the filtering algorithms are applied for the analysis of images to effectively identify the targeted region. In the third stage, more developed algorithm is utilized to evaluate the image characteristics in the targeted region, identifying the basic image outline. Lastly, the reduction algorithm is meant to transform the original image into significantly precise and smooth pictures. The experimental findings indicate that the machine vision-centred clinical image analysis algorithm might significantly extract fundamental data and attain the most reliable results, contrasting with the most ancient image analysis techniques.
