Published: April 2019

Objective: To study the factors in the development of atrial fibrillation in patients with subclinical hyperthyroidism on the background of angina pectoris as a result of a comprehensive analysis of the electrocardiographic and echocardiographic indicators of the heart, thyroid volume, thyroid hormone levels and lipid profile.

Materials and Methods: The risk factors for atrial fibrillation (AF) were studied in patients with subclinical hyperthyroidism (SH) and angina pectoris. It was revealed that the starting factor for the occurrence of AF in patients with subclinical hyperthyroidism is a shift in the reference values of thyroid hormones. It was established that the total depression of the ST segment reflects the degree of coronary reserve in patients with AF on the background of SH.

Results and Discussion: It has been shown that in patients with subclinical hyperthyroidism, there is a normal level of total cholesterol and LDLP, a low level of triglycerides and atherogenicity, and a high level of HDLP. When combined with subclinical hyperthyroidism and paroxysmal AF, there is an increase in the level of total cholesterol, LDLP, TG, atherogenicity and decreased HDLP.

Conclusion: It has been proven that diastolic dysfunction of the left ventricle of the first type is formed on the background of SH.

Published: April 2019

Introduction: Auricular deformity can be emotionally traumatising and affects social behavior of an individual. In such cases, aesthetically acceptable prosthesis serves as a viable alternative technique to surgical reconstruction.

Case description: Impression of the auricular defect was taken by light and regular body of poly vinyl siloxane impression material. Wax sculpting was challenging due to the bulgy remnant of the defected ear. The wax pattern was made very thin to accommodate and mask the remnant without compromising the aesthetic. Trial on the patientwas done for correction of the contours, angulation, height and width according to the normal contralateral ear. The intrinsic coloration of a Room Temperature Vulcanizing silicone was done and poured in a custom-made three-piece mold. Before the final issue of the auricular prosthesis, extrinsic coloration was done based on the surrounding area of the defect.

Discussion: Fabrication of adhesive retained prosthesis is challenging in patients with large deformed soft tissue who refuse to undergo surgical repair. A modified wax sculpting was done to overcome this challenge. Medical grade silicone was the choice of material because of its flexibility, biocompatibility and life like appearance.

Conclusion: Replacement of missing ear is a difficult and multi-step task in which extensive array of materials and techniques need to be employed. This fabrication technique is alternative to surgical repair with the utilization of available and economical materials.

Vocational education (VET) requires collaboration between schools and workplaces in order to get a coherent education of good quality. The Norwegian vocational education has a model of four years where students complete two years of education at school, and the remaining two years as an apprenticeship in a company. The subject Vocational indepth learning is introduced to strengthen the transition between school and companies, and gives the students an opportunity to train in companies during the two first years in school. Previous studies show that cooperation between school and companies is random and has potential of improvement. Previous studies focus on the perspective of schools and students. In this article, we enquire the companies’ perspectives and needs. We have investigated the companies’ reasons to receive students and the students influence on the work places. Our findings show that the main motivation for receiving students is to ensure recruitment. We also find that the presence of the students affects the working environment and may lead to higher work satisfaction for the mentors. Within certain areas, the students also contribute to development of the employees.

Published: April 2019

Bio-actuators that use insect muscular tissue have attracted attention from researchers worldwide because of their small size, self-motive property, self-repairer ability, robustness, and the need for less environment management than mammalian cells. To demonstrate the potential of insect muscular tissue for use as bio-actuators, three types of these robots, a pillar actuator, a walker, and a twizzer, have been designed and fabricated. However, a model of an insect muscular tissue-powered swimming robot that is able to float and swim in a solution has not yet been reported. Therefore, in this paper, we present a prototype of an insect muscular tissue-powered autonomous micro swimming robot that operates at room temperature and requires no temperature and pH maintenance. To design a practical robot body that is capable of swimming by using the force of the insect dorsal vessel (DV), we first measured the contraction force of the DV. Then, the body of the swimming robot was designed, and the design was confirmed by a simulation that used the condition of measured contraction force. After that, we fabricated the robot body using polydimethylpolysiloxane (PDMS). The PDMS body was obtained from a mold that was fabricated by a stereo lithography method. Finally, we carefully attached the DV to the PDMS body to complete the assembly of the swimming robot. As a result, we confirmed the micro swimming robot swam autonomously at an average velocity of 11.7 μm/s using spontaneous contractions of the complete insect DV tissue. These results demonstrated that the insect DV has potential for use as a bio-actuator for floating and swimming in solution.
A Multi-Parameter Approach for Apricot Texture Analysis
Authors: Gabioud Rebeaud Séverine , Jaylet Alice , Cotter Pierre-Yves , Camps Cédric , Christen Danilo
Published: April 2019

Apricots have a short storage life principally caused by a rapid softening, which increases the sensitivity of the fruit to mechanical damage, and to the development of fungal diseases. The current methods to assess fruit firmness give limited information on the evolution and the mechanisms of softening. With the aim of developing novel strategies to better monitor fruit softening, a multi-parameter approach measuring textural properties was evaluated and compared to a reference method whose results are obtained from a unique parameter. ‘Goldrich’ and ‘Orangered®’ apricots were used in this study as representative cultivars with substantially different post-harvest behavior. The results showed that this multi-parametric approach allows detailed evaluation of the influence of storage conditions on apricots’ textural properties. The correlations found between firmness values measured by the standard method and the multiple textural parameters obtained by the compression and the puncture tests on the fruit flesh had r-values ranging from 0.6 to 0.78. Parameters related to the skin were, however, poorly correlated with the standard method, with r-values all below 0.4. Taken together, these results demonstrate that a multi-parameter approach allows a better understanding of how storage conditions influence the softening of apricots in a cultivar-specific manner.
Electro-Precipitation of Actinides on Boron-Doped Diamond Thin Films for Solid Sources Preparation for High-Resolution Alpha-Particle Spectrometry
Authors: Tran Quang-Thuan , Pierre Sylvie , de Sanoit Jacques , Pomorski Michal , Bergonzo Philippe
Published: April 2019

In this work, we investigate a novel approach to prepare high-performance alpha-particle solid sources fabricated on diamond thin support layers, offering the properties of diamond such as a low-Z material with corrosion and mechanical hardness. As-prepared solid sources onto boron-doped-diamond (BDD) substrate exhibited high performance of the autoradiography and spectroscopic resolution at the level of other more conventional materials such as stainless steel. A straightforward precipitation process in the Na2SO4 or NaNO3 simple electrolytes under mild experimental conditions with a low current of several mA.cm−2 were successfully developed onto BDD substrates for deposition of single 241Am as well as 239Pu, 241Am, and 244Cm mixed radionuclides. The results demonstrate that solid sources deposited onto such BDD substrates can match the performance of those prepared onto stainless steel substrates with excellent uniformity and high-resolution spectroscopy, together combining the robustness, chemical resilience, and X-ray transparence of the diamond. Alpha-particle spectra exhibiting a low full width at half maximum (FWHM) of 12.5 keV at the energy of 5.485 MeV (241Am) could be practically obtained for BDD substrates.

Australian Indigenous Art Innovation and Culturepreneurship in Practice: Insights for Cultural Tourism
Authors: Loaney Denis R.
Published: April 2019

Indigenous cultural tourism offers significant future opportunities for countries, cities and Indigenous communities, but the development of new offerings can be problematic. Addressing this challenge, this article examines contemporary Australian Indigenous art innovation and cultural entrepreneurship or culturepreneurship emanating from Australia’s remote Arnhem Land art and culture centres and provides insight into the future development of Indigenous cultural tourism. Using art- and culture-focused field studies and recent literature from the diverse disciplines of art history, tourism, sociology and economics, this article investigates examples of successful Indigenous artistic innovation and culturepreneurship that operate within the context of cultural tourism events. From this investigation, this article introduces and defines the original concept of Indigenous culturepreneurship and provides six practical criteria for those interested in developing future Indigenous cultural tourism ventures. These findings not only challenge existing western definitions of both culture and culturepreneurship but also affirm the vital role of innovation in both contemporary Indigenous art and culturepreneurial practice. Equally importantly, this investigation illuminates Indigenous culturepreneurship as an important future-making socio-political and economic practice for the potential benefit of Indigenous communities concerned with maintaining and promoting their cultures as living, growing and relevant in the contemporary world.

Pyrite/arsenopyrite (Py-AsPy), galena (PbS), and sphalerite (ZnS) concentrates from the flotation plants of Olympias and Stratoni (Kassandra mines, Chalkidiki, N. Greece) were investigated for their major, trace, minor, and critical element contents, including actinides associated to natural radioactivity. It is revealed that in addition to the Pb, Zn, Ag, and Au being exploited by Hellas Gold S.A., there are also significant concentrations of Sb and Ga (Sb: >0.2 wt.% in PbS concentrate; Ga:25 ppm in ZnS concentrate), but no considerable contents of Bi, Co, V, or REE. Concerning other elements, As was found in elevated concentrations (>1 wt.% in Py-(As)Py-AsPy Olympias concentrate and almost 1 wt.% in Stratoni PbS and ZnS concentrates) together with Cd (specifically in ZnS concentrate). However, actinides occurred in very low concentrations (U < 2 ppm and Th < 0.5 ppm in all examined concentrates), limiting the possibility of natural radioactivity in the Hellas Gold S.A. products. The concentrations of the natural radionuclides (238U, 232Th, and 40K) are much lower than those of commercial granitic rocks, and thus the associated radioactive dose is insignificant.

Hepatocellular carcinoma (HCC) ranks fifth in occurrence and second in mortality of all cancers. The development of effective therapies for HCC is urgently needed. Anticancer drugs targeted to the liver-specific asialoglycoprotein receptors (ASGPRs) are viewed as a promising potential treatment for HCC. ASGPRs facilitate the recognition and endocytosis of molecules, and possibly vehicles with galactose end groups, by the liver. In this study, bovine serum albumin (BSA) was conjugated with lactose using a thermal treatment. The formation of lactosylated BSA (BSA-Lac) was confirmed by a change of the chemical structure, increased molecular mass, and Ricinus communis lectin recognition. Subsequently, the low-crosslinking BSA-Lac nanoparticles (LC BSA-Lac NPs) and high-crosslinking BSA-Lac nanoparticles (HC BSA-Lac NPs) were synthesized. These nanoparticles presented spherical shapes with a size distribution of 560 ± 18.0 nm and 539 ± 9.0 nm, as well as an estimated surface charge of −26 ± 0.15 mV and −24 ± 0.45 mV, respectively. Both BSA-Lac NPs were selectively recognized by ASGPRs as shown by biorecognition, competition, and inhibition assays using an in vitro model of HCC. This justifies pursuing the strategy of using BSA-Lac NPs as potential drug nanovehicles with selective direction toward hepatocellular carcinoma.
Corrosion Assessment of Myo-Inositol Sugar Alcohol as a Phase Change Material in Storage Systems Connected to Fresnel Solar Plants

Published: April 2019

Thermal energy storage systems work in conjunction with solar technologies with the aim of increasing their dispatchability and competitiveness in the energy market. Among others, latent heat thermal energy storage systems have become an appealing research subject and many efforts have therefore been invested in selecting the best phase change material (PCM) to fit the final application. In this study, an extended corrosion characterization was performed for two PCM candidates, solar salt (40 wt.% KNO3/60 wt.% NaNO3) and myo-inositol (C6H12O6), to be applied in Fresnel solar plants. Corrosion rates were determined in aluminium, stainless steel (AISI 304), carbon steel (AISI 1090), and copper by gravimetric tests, gauging the weight loss after 2000 h of immersion at 250 °C. The corrosion products were characterized by scanning electron microscopy (SEM) and x-ray diffraction (XRD). The corrosion tests carried out with myo-inositol did not show accurate enough results to draw conclusions regarding corrosion on the metals. However, it was observed that this sugar alcohol strongly sticks to the metal specimens, making myo-inositol extremely difficult to manage as an energy storage material. Therefore, the present paper discourages the use of myo-inositol as a PCM beyond its corrosion rate.

Published: April 2019

We present a study of magnetic structures with controllable effective exchange energy for Josephson switches and memory applications. As a basis for a weak link we propose to use a periodic structure composed of ferromagnetic (F) layers spaced by thin superconductors (s). Our calculations based on the Usadel equations show that switching from parallel (P) to antiparallel (AP) alignment of neighboring F layers can lead to a significant enhancement of the critical current through the junction. To control the magnetic alignment we propose to use a periodic system whose unit cell is a pseudo spin valve of structure F1/s/F2/s where F1 and F2 are two magnetic layers having different coercive fields. In order to check the feasibility of controllable switching between AP and P states through the whole periodic structure, we prepared a superlattice [Co(1.5 nm)/Nb(8 nm)/Co(2.5 nm)/Nb(8 nm)]6 between two superconducting layers of Nb(25 nm). Neutron scattering and magnetometry data showed that parallel and antiparallel alignment can be controlled with a magnetic field of only several tens of Oersted.

Published: April 2019

In the present paper we consider second order compact upwind schemes with a space split time derivative (CABARET) applied to one‐dimensional compressible gas flows. As opposed to the conventional approach associated with incorporating adjacent space cells we use information from adjacent time layer to improve the solution accuracy. Taking the first order Roe scheme as the basis we develop a few higher (i.e. second within regions of smooth solutions) order accurate difference schemes. One of them (CABARET3) is formulated in a two‐time‐layer form, which makes it most simple and robust. Supersonic and subsonic shock‐tube tests are used to compare the new schemes with several well‐known second‐order TVD schemes. In particular, it is shown that CABARET3 is notably more accurate than the standard second‐order Roe scheme with MUSCL flux splitting.

This article is devoted to further investigation of numerical methods for one differential problem of mixed type. We consider a two‐dimensional first‐order differential equation with one complex‐valued and one real constant coefficients. So, we have an elliptic problem with respect to the first argument and a hyperbolic problem with respect to the second one. The equations of such type are generalized transfer equations. Firstly, the correctness of the problem stated is discussed. Secondly, possible difference scheme of the multicomponent modification of the alternating direction method is proposed. Its stability and convergence is investigated. Results of numerical experiments on modelling of nonlinear regime of surface volume free electron laser are analyzed.

Insects are becoming part of the human diet in many regions of the world, either directly or indirectly, as livestock feed. Insects could become a significant feed ingredient if produced at industrial scale, but it is a challenge. Such an emerging sector would result in substantial social effects. One innovation of the DESIRABLE project is exploring potential social consequences induced by industrial scale development of insect production in France for feed, under several production and marketing assumptions. First, this paper explains how the stakeholders and researchers involved in the project built and selected some framework scenarios, which depict upstream (production and meal processing) scenarios. Downstream scenarios were designed based on interviews with specialists in poultry, trout, and feed production markets, that allowed to proposing plausible scenarios for marketing. The potential outlets are more or less narrow market ‘niches’: feed for laying hens to produce organic eggs, or for farmed trout eating insect meal. Second, the method for evaluating social effects linked with the emergence of the new insect’ industry, a social life cycle analysis in four detailed scenarios. The main positive social effects of the four detailed scenarios result from job creation in the insect production sector, while effects on other feed-ingredient suppliers are few. Negative effects result from the allergy risk for employees and potential disturbance to nearby neighbourhoods, but the latter can be easily managed by carefully choosing the locations. In the two scenarios with integrated bio refinery, exists a major risk that could stop the industrial project: activists could use environmental or animal-welfare concerns to oppose the bio refinery, because of agricultural land and water preservation and/or opposition to industrial scale insect production. Nevertheless, insect meal can help preserve fishery resources by providing a constant substitute for fish meal.

The aim of this article is to develop a method in order to investigate the surface modifications of degraded polyacrylonitrile powders under microwave treatment in air. Microwave treatment of polyacrylonitrile powders in air recorded two stages of degradation firstly an exothermic reaction that started in the range of (86-117)°C. Secondly the Thermal runway here the weight loss reached a peak value between 80-90 percent with the small quantity of 0.25g polyacrylonitrile and in the ashes with a bigger quantity 1g of polyacrylonitrile. Scanning electron microscopy analysis technique revealed the morphological characteristics and the porosity of the carbon compound that may play an important role in the construction of high porosity area and so in electrochemical supercapacitor devices with high performances.

Multiple Locus Variable Number of Tandem Repeat (VNTR) analysis has been proposed as a means of genotyping for tracking leprosy transmission due to tandem repeats’ potential as genetic markers to differentiate M. leprae strains. However, characteristics of polymorphism can vary depending on the population. This study aimed to compare the copy number of repeats in four genetic markers: TTC, AC8a, AC9 and 6-7 in leprosy patients from Surabaya and Bandung. Twenty three patients from Dr. Soetomo General Hospital and 21 from Hasan Sadikin Hospital were recruited. Multiple locus VNTR analysis was applied using total DNA extracts from Slit Skin Smear (SSS). From Surabaya, 7 samples showed the same copy number of four genetic markers (TTC=15; AC8a=10; AC9=10 and 6-7=6) and 2 showed another (TTC=16; AC8a=10; AC9=11 and 6-7=6); as for samples from Bandung, 2 showed the same copy number (TTC=15; AC8a=8; AC9=10 and 6-7=8) and 2 showed another (TTC=16; AC8a=10; AC9=11 and 6-7=6). The multiple locus VNTR analysis showed two identical M. leprae VNTR profiles from Bandung and Surabaya which supports the use of VNTR loci for transmission studies.

Vitiligo is an acquired depigmentation disorder with exact etiology is not yet known. Autoimmune hypothesis plays an important role in the mechanism of vitiligo and has been related to lower levels of 25- hydroxyvitamin D (25-(OH)D). This study aimed to analyze the comparison effect of combination therapy of NB-UVB phototherapy and vitamin D3 supplement toward NB-UVB phototherapy alone to increase of serum 25-(OH)D levels in vitiligo patients. Subjects consisted of 24 adult vitiligo patients: group I was given a combination of NB-UVB phototherapy and 5000 IU vitamin D3 once daily; while group II was given monotherapy of NB-UVB. There was a very significant increase of serum 25- (OH)D level in group I with an average increase was 288.65%, while group II showed a significant increase of serum 25- (OH)D serum with an average increase was 33.63%. The very significant result was seen between both groups. None of the subjects showed signs of vitamin D toxicities during treatment. The study concluded that combination of NB-UVB phototherapy and vitamin D3 supplementation gave a better effect to increase of serum 25-(OH)D levels in adult vitiligo patients.
Diffuse lepromatous leprosy caused by dual infection of mycobacterium leprae and mycobacterium lepromatosis: A case report
Authors: Widiatma Ridha Ramadina , Sukanto Hari
Published: April 2019

M. lepromatosis is the dominant cause of leprosy in Mexico and it co-exists with M. leprae in endemic areas as the once elusive second cause of leprosy. A 41-year-old Madurese woman came with multiple ulcer on her legs, hands and buttock. The ulcers were described as wide and deep, covered with blackish crusts and some exudative area with irregular edges. On face, there were difusse infiltration, madarosis and saddle nose. Histopathology showed thinning of epidermis with a lot of foam cells containing BTA, including endotel and perivascular tissues. Nested PCR examination with LERF2-MLER4 primers for detecting M. leprae showed a positive result. Advanced PCR examination using LPMF2-MLER4 primers for detecting M. lepromatosis also showed a positive result. Based on the clinical, hystopathological results and PCR examination, it was consistent with diffuse lepromatous leprosy. M. lepromatosis mainly causes lepromatous leprosy and also specifically diffuse lepromatous leprosy.

Student nurses’ perceptions of their educational environment at a school of nursing in Western Cape province, South Africa: A cross-sectional study
Authors: Mthimunye Katlego D.T. , Daniels Felicity M.
Published: April 2019

Background: Educational environments have been found to bear a substantial relationship with the academic performance and success, as well as the retention, of students.Objectives: The study objectives were to (1) evaluate the educational environment as perceived by undergraduate nursing students at a school of nursing (SON) in Western Cape province and (2) investigate whether the educational environment, or components thereof, is perceived negatively or positively among undergraduate nursing students of different year level, gender, home language and ethnicity.Method: A quantitative research method with a cross-sectional design was implemented. Data were collected from 232 undergraduate nursing students from a SON at a university in Western Cape province, South Africa. The subscales and the items of the educational environment questionnaire were compared among undergraduate nursing students. Data were analysed by means of the IBM Statistical Package for Social Sciences (IBM SPSS-24) using analysis of variances (ANOVAs), independent-sample t-tests, mean scores, standard deviations and percentages.Results: The mean score attained for the entire participant group was 195 (standard deviation [SD] = 24.2) out of 268 (equivalent to 72.8% of maximum score), which indicated that the educational environment was perceived substantially more positively than negatively. The overall mean score was significantly higher (p < 0.05) for male students (M = 202; SD = 21) and for black students (M = 202; SD = 21). The digital resources (DR) subscale was the only subscale with a statement or item that was rated as absolute negative (M = 1.9; SD = 0.9).Conclusion: The educational environment at the institution concerned was perceived as predominantly positive by its undergraduate nursing students. Although the educational environment was predominantly perceived as positive, the results of this study also indicated that enhancements are required to improve the physical classroom conditions, skills laboratories, DR and the implemented teaching and learning strategies. It is vital for university management to prioritise the creation of an educational environment which would ensure that quality learning takes place.
