Authors: Zotovich I. G. , Lukyanova M. N.
Published: December 2020

Budget revenues of public-legal institutions form the financial base providing bodies of state power and local selfgovernance with cash necessary to perform their authorities on organizing overall development of economic and social spheres of territories. The article studies conditions of shaping budget revenue of municipal bodies and analyzes difficulties of municipal budget filling in view of national legislation. Problems in municipal administration work are shown, which are envisaged by the absence of stimuli to effective and efficient functioning of municipal clerks. Practices of participation (people’s) budgeting are described and the impact of this tool on budget revenue shaping is estimated. The article demonstrates possibilities of concession agreements and contracts of state-private partnership, which can decrease the burden on the municipal budget connected with projects dealing with repair and reconstruction of property. On the basis of materials studied by methods of comparative analysis, structural and dynamic analysis of local budget revenues, critical analysis, method of searching for new scientific categories and concepts, logical and deductive methods recommendations were worked out on issues of regulating the missing revenues (tax expenses) and introduction of digital technologies of tax administration.

Ziziphus spina-christi Leaf Extract Mitigates Mercuric Chloride-induced Cortical Damage in Rats
Authors: Almeer Rafa S. , Alkahtani Saad , Alarifi Saud , Moneim Ahmed E. Abdel , Abdi Saba , Albasher Gadah
Published: December 2020

Background:

Mercuric chloride (HgCl2) severely impairs the central nervous system
when humans are exposed to it.

Aims:

We investigated the neuroprotective efficiency of Ziziphus spina-christi leaf extract
(ZSCLE) on HgCl2-mediated cortical deficits.

Methods:

Twenty-eight rats were distributed equally into four groups: the control, ZSCLE-treated
(300 mg/kg), HgCl2-treated (0.4 mg/kg), and ZSCLE+HgCl2-treated groups. Animals received
their treatments for 28 days.

Results:

Supplementation with ZSCLE after HgCl2 exposure prevented the deposition of mercury
in the cortical slices. It also lowered malondialdehyde levels and nitrite and nitrate formation,
elevated glutathione levels, activated its associated-antioxidant enzymes, glutathione reductase,
and glutathione peroxidase, and upregulated the transcription of catalase and superoxide dismutase
and their activities were accordingly increased. Moreover, ZSCLE activated the expression of
nuclear factor erythroid 2-related factor 2 and heme oxygenase-1 when compared with the HgCl2
group. Notably, post-treatment with ZSCLE increased the activity of acetylcholinesterase and
ameliorated the histopathological changes associated with HgCl2 exposure. Furthermore, ZSCLE
blocked cortical inflammation, as observed by the lowered mRNA expression and protein levels of
interleukin-1 beta and tumor necrosis factor-alpha, as well as decreased mRNA expression of
inducible nitric oxide synthase. In addition, ZSCLE decreased neuron loss by preventing apoptosis
in the cortical tissue upon HgCl2 intoxication.

Conclusion:

Based on the obtained findings, we suggest that ZSCLE supplementation could be
applied as a neuroprotective agent to decrease neuron damage following HgCl2 toxicity.

Authors: Aziz Ayesha , Asif Muhammad , Ashraf Ghazala , Yang Qiaoli , Wang Shenqi
Published: December 2020

Background:

The spread of COVID-19 has become a growing cause of mortalities over the globe since its major outbreak in December 2019. The scientific and medical communities are rallying to study different strains and probable mutations to develop more rapid and reliable molecular diagnostic tests and possible therapeutic approaches for SARS-CoV-2.

Introduction:

In the first section, following the introductory part, we shed light on structural and pathogenic features of SARS-CoV-2 and risk factors related to age, gender, neonatal and comorbidities. The next section summarizes the current diagnostic tests for COVID-19, such as nucleic acid and computed tomography (CT) techniques, with further emphasis on emerging diagnostic approaches for COVID-19.

Methods:

Further, we also review the ongoing therapeutic practices which can block virus-host interaction, cease viral proliferation or inhibit hyperbolic host immune response with subsections on drug therapy, cell therapy, immunotherapy and herbal medicines that are being used for the possible treatment of patients.

Results and conclusion:

Among the different promising drugs, remdesivir, by inhibiting the RNA-dependent RNA-Polymerase activity, gives much better results, including declined viral load and quick lung tissue recovery. The long-lasting repercussions of COVID-19 have also been discussed at the end. In this review, we have also critically discussed the progress in several vaccines that are under development.
Recent developments and opportunities in fighting COVID-19
Authors: Rao Vikram , Bhattamisra Subrat Kumar
Published: December 2020

Background:

COVID-19, a Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCov-
2), was first diagnosed in the patients from Wuhan, China, in December 2019. Within a couple
of months of infection, it was declared as pandemic by the World health organization.
COVID-19 has become the most contagious infection with a serious threat to global health. In this
review, we aimed to discuss the pathogenesis, diagnostics, current treatments and potential
vaccines for COVID-19.

Methods:

An extensive literature search was conducted using keywords “COVID-19”; “Coronavirus”;
“SARS-Cov-2”; “SARS” in public domains of Google, Google scholar, PubMed, and ScienceDirect.
Selected articles were used to construct this review.

Results:

SARS-Cov-2 uses the Spike (S) protein on its surface to recognize the receptor on angiotensin-
converting enzyme 2 (ACE2) and bind with 10-folds greater affinity than SARS-Cov-1.
Molecular assays and immunoassays are the most frequently used tests, whereas computed tomography
(CT) scans and artificial intelligence enabled diagnostic tools were also used in patients. In
therapeutic treatment, few drugs were repurposed and about 23 therapeutic molecules, including
the repurposed drugs are at different stages of the clinical trial. Similarly, the development of
vaccines is also in the pipeline. Few countries have managed well to contain the spread by rapid
testing and identifying the clusters.

Conclusion:

Till now, the acute complications and mortality of COVID-19 have been linked to
pre-existing comorbid conditions or age. Besides the development of therapeutic strategies that include
drugs and vaccine, the long term implication of COVID-19 infection in terms of the disorder/
disability in the cured/discharged patients is a new area to investigate.

Published: December 2020

Background:

Currently, the present world is facing a new deadly challenge against a pandemic disease called
COVID-19, which is caused by a coronavirus, named SARS-CoV-2. To date, there is no drug or vaccine that can treat
COVID-19 completely, but some drugs have been used primarily, and they are in different stages of clinical trials. This
review article discussed and compared those drugs which are running ahead in COVID-19 treatments.

Methods:

We have explored PUBMED, SCOPUS, WEB OF SCIENCE, as well as press release of WHO, NIH and FDA for
articles about COVID-19, and reviewed them.

Results:

Drugs like favipiravir, remdesivir, lopinavir/ritonavir, hydroxychloroquine, azithromycin, ivermectin,
corticosteroids and interferons have been found effective in some extents, and partially approved by FDA and WHO to treat
COVID-19 at different phases of pandemic. However, some of these drugs have been disapproved later, although clinical
trials are going on. In parallel, plasma therapy has been found fruitful in some extents too, and a number of vaccine trails are
going on.

Conclusions:

This review article discussed the epidemiologic and mechanistic characteristics of SARS-CoV-2, and how
drugs could act on this virus with the comparative discussion on progress and backwards of major drugs used till date,
which might be beneficial for choosing therapies against COVID-19 in different countries.

Authors: Jafari Mohammad ALI , Gharahveysi Shahabodin
Published: December 2020

Objective. The study was to study the effect of canola processing on the intestine traits, blood metabolites, and kidney enzymes of broiler breeders. Material and methods. Four hundred fifty broiler breeder hens were used for 3 months. The completely randomized design was used with 6 treatments (unprocessed, processed by Lactobacillus Plantarum, Bacillus Subtilis, Aspergillus Oryzae, Neurospora Cytophilla, and Alkalase enzyme) and 5 replications. The collected data were analyzed by the LSmeans procedure of SAS statistical software. Results. The effects of treatments were significant on blood metabolites (p<0.05). Glucose concentration and High-density lipoprotein (HDL) were increased by processing methods. Also, the caecum, jejunum and duodenum weight were influenced(p<0.05). The weight of the duodenum and jejunum was increased and caecum weight was decreased. The processing of canola meal increased the length of the villi and decreased the depth of the crypt of the jejunum (p<0.05). Treatments effect was significant on the Alanine transaminase (ALT) and Alkaline phosphatase (ALP) (p<0.05). The effect of treatments was significant on the digestive amylase, lipase and protease activity (p<0.05). The canola process improved its digestibility. In other words, its protein quality, fatty acid profile and antimicrobial properties were improved. Conclusions. The different processing methods of canola improved the hen’s traits. It can be recommended to use the processed meal instead of the raw canola meal.
Mortality Prediction of Patients With Cardiovascular Disease Using Medical Claims Data Under Artificial Intelligence Architectures: Validation Study
Authors: Tran Linh , Chi Lianhua , Bonti Alessio , Abdelrazek Mohamed , Chen Yi-Ping Phoebe
Published: December 2020

Background

Cardiovascular disease (CVD) is the greatest health problem in Australia, which kills more people than any other disease and incurs enormous costs for the health care system. In this study, we present a benchmark comparison of various artificial intelligence (AI) architectures for predicting the mortality rate of patients with CVD using structured medical claims data. Compared with other research in the clinical literature, our models are more efficient because we use a smaller number of features, and this study could help health professionals accurately choose AI models to predict mortality among patients with CVD using only claims data before a clinic visit.

Objective

This study aims to support health clinicians in accurately predicting mortality among patients with CVD using only claims data before a clinic visit.

Methods

The data set was obtained from the Medicare Benefits Scheme and Pharmaceutical Benefits Scheme service information in the period between 2004 and 2014, released by the Department of Health Australia in 2016. It included 346,201 records, corresponding to 346,201 patients. A total of five AI algorithms, including four classical machine learning algorithms (logistic regression [LR], random forest [RF], extra trees [ET], and gradient boosting trees [GBT]) and a deep learning algorithm, which is a densely connected neural network (DNN), were developed and compared in this study. In addition, because of the minority of deceased patients in the data set, a separate experiment using the Synthetic Minority Oversampling Technique (SMOTE) was conducted to enrich the data.

Results

Regarding model performance, in terms of discrimination, GBT and RF were the models with the highest area under the receiver operating characteristic curve (97.8% and 97.7%, respectively), followed by ET (96.8%) and LR (96.4%), whereas DNN was the least discriminative (95.3%). In terms of reliability, LR predictions were the least calibrated compared with the other four algorithms. In this study, despite increasing the training time, SMOTE was proven to further improve the model performance of LR, whereas other algorithms, especially GBT and DNN, worked well with class imbalanced data.

Conclusions

Compared with other research in the clinical literature involving AI models using claims data to predict patient health outcomes, our models are more efficient because we use a smaller number of features but still achieve high performance. This study could help health professionals accurately choose AI models to predict mortality among patients with CVD using only claims data before a clinic visit.
Coronavirus Pandemic Refugees and the Future of American Cities
Authors: Johnson, Jr. James H.
Published: December 2020

Paralleling crisis behavior in prior pandemics and continuing a contemporary migration trend already underway, wealthy individuals and families as well as remote workers in a host of other demographic groups are fleeing major, high cost, densely settled urban centers in response to the Covid-19 pandemic. These coronavirus pandemic refugees are relocating to less densely settled suburbs, exurbs, and rural areas—creating, in some instances, new “Zoom Towns.” The implications for the future viability of large cities are far ranging if, unlike prior pandemics, the social distance moves of coronavirus pandemic refugees and the aversion to dense urban living continue post-Covid-19.
The Berlin Wall as Living Ornament
Authors: Parte Christina
Published: December 2020

In this article I argue, based on Gilles Deleuze’s concept of affect, that the aesthetics of the Berlin Wall, i.e., the aesthetics of the different generations of the Wall itself (especially the last generation of the Wall) and the artistic interventions on the Western side of the Wall, in form of graffiti and wall art, have created effects which not necessarily challenge the Wall’s function as a border fortification system, but incorporate it in dialectical form. Affects triggered by the Western Wall’s sensational effects and its meandering course through the divided city have animated the Wall in such a way, that the Wall transforms into a living ornament. I read the Wall’s aesthetics as Baroque, in which façade and inner structure are seemingly unrelated but not separate and condition each other. I argue that the growing tension between Western surface intervention and Eastern military structure have the potential to bring forward states of e/motion, which I term in the Deleuzian sense: becoming political.
Intervención grupal online para la elaboración del duelo y recuperación del bienestar psicológico tras una ruptura amorosa
Authors: Navarro Vásquez Perla
Published: December 2020

Este estudio buscó verificar si aumentaban los niveles de bienestar psicológico en personas que han vivido una ruptura amorosa, luego de participar de una intervención grupal de modalidad online basada en el modelo de tareas del duelo de Worden, y el uso de técnicas recomendadas por este autor para el trabajo de duelo. La muestra final del estudio estuvo compuesta por 12 participantes adultos, residentes en la República Dominicana. La recolección de datos cuantitativos se hizo con el uso de las Escalas de Bienestar Psicológico de Ryff en su adaptación española realizada por Rodríguez-Carvajal et al. (2010). Además, se recolectaron datos cualitativos a través de un cuestionario de preguntas abiertas. Los resultados muestran un aumento significativo en los niveles de bienestar psicológico tras la intervención (m=28.58; t=5.86, p<0.001). Los hallazgos cualitativos, clasificados en cinco categorías principales, evidencian la percepción de cambios positivos en los participantes luego de haber participado de la intervención, como el desarrollo de la empatía con los miembros del grupo, el cambio de ideas erróneas que pudieran interferir en el proceso de duelo y la motivación para continuar procesos terapéuticos. Se recomienda realizar otras investigaciones con una muestra mayor y con grupo control, de modo que puedan hacerse generalizaciones y conclusiones definitivas sobre la efectividad del programa diseñado y aplicado.
Popularidad presidencial y éxito o derrota del partido en el gobierno. El caso de República Dominicana 2004-2020
Authors: Díaz Rodríguez Orestes Enrique , Santibáñez Espinosa de los Monteros Andrea
Published: December 2020

Se ha considerado que la popularidad de los mandatarios latinoamericanos tiene la capacidad de anticipar el éxito o derrota del partido en el gobierno. El artículo contrasta la popularidad de los presidentes dominicanos con los resultados electorales del oficialismo comprobando que la tendencia a la asociación también tiende a ser mayoritaria. Especialmente, la experiencia comparada demuestra que la baja aprobación del mandatario de turno no anticipa la derrota del partido en el gobierno si el principal partido de la oposición no constituye una opción de gobierno creíble, el artículo también analiza el caso de los comicios presidenciales de 2012. La verificación de los indicadores empíricos del concepto “oposición no es creíble” y la revisión crítica de las interpretaciones académicas sobre las causas del desenlace de las elecciones de 2012 sugieren que la oposición deja también de constituir una alternativa de gobierno creíble si en el pasado relativamente reciente tuvo un desastroso desempeño gubernamental. Por último, la experiencia comparada consigna que la alta aprobación del mandatario de turno no anticipa el éxito del oficialismo si la división interna afecta a esa fuerza política. Sometemos a verificación esa explicación y comprobamos que la participación del gobernante Partido de la Liberación Dominicano en los comicios presidenciales de 2020 se vio afectada por un proceso de esa naturaleza. La originalidad de la investigación reside en corroborar que también para el caso de República Dominicana la aprobación presidencial es un predictor robusto del éxito o derrota del partido en el gobierno.
Kazan art exhibitions of the 19th – 20th centuries as sources of formation of the city’s museum collections
Authors:   State Museum of Fine Arts of the Republic of Tatarstan, Akhmetova Dina I.
Published: December 2020

The creation of an art school in 1895 under the patronage of the Academy of Arts is an important milestone in the life of the Kazan Province center. As a result, Kazan combines various vectors of cultural activities: getting an art education, organizing exhibitions, and uniting the local creative intelligentsia. For the first time, rare but already regular exhibitions are held in the city. Initially, these were exhibitions of the academic school masters of the capital. Later, united by the school, Kazan artists felt up to the task of organizing their own exhibitions. The result of these events is the formation of the school’s museum, as well as the development of the city’s private collections. The City Museum also acquired works of art for its own funds. Artist A. Kandaurov laid the foundation of the school museum and presented two of his paintings in 1896. Afterwards it became a tradition – artists donated their works to the school museum. As a result, in 1902, the school petitioned the Academy “to create a museum and a gallery in the new school building using the stock of the Academy of Arts”. Many of the works purchased at such exhibitions were included in the collection of the Republic of Tatarstan State Museum of Fine Arts. The organization of art exhibitions made Kazan a part of the all-Russian cultural space of those years.
Tatar mullahs sent to the steppe “for clarification, disclosure and implementation of the rules”
Authors:   Al-Farabi Kazakh National University, Sultangaliyeva Gulmira S.
Published: December 2020

The article presents materials on the intermediary role of Tatar mullahs in the process of implementing administrative reforms in the 20–30s of 19th century on the territory of the Middle and Junior zhuzes. The Tatar mullahs, both with the diwan [okruzhnoy prikaz], the volost sultans of the Siberian Kazakh region and with the three parts (Western, Middle, Eastern) of the Orenburg Kazakh region, were engaged not only in explaining the rules of the imperial laws in the Kazakh Steppe. In fact, the range of their activities was wide: taking the oath of senior sultans and sultan rulers, organizing paperwork, teaching Kazakh children Tatar literacy, collecting information about inner political events in Kazakh nomads for the regional administration and St. Petersburg, tracking the mood of the Kazakh population and the behavior of the Kazakh nomadic elite representatives.

Published: December 2020

OBJECTIVE

To estimate the health utility impact of diabetes-related complications in a large, longitudinal U.S. sample of people with type 2 diabetes.

RESEARCH DESIGN AND METHODS

We combined Health Utilities Index Mark 3 data on patients with type 2 diabetes from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) and Look AHEAD (Action for Health in Diabetes) trials and their follow-on studies. Complications were classified as events if they occurred in the year preceding the utility measurement; otherwise, they were classified as a history of the complication. We estimated utility decrements associated with complications using a fixed-effects regression model.

RESULTS

Our sample included 15,252 persons with an average follow-up of 8.2 years and a total of 128,873 person-visit observations. The largest, statistically significant (P < 0.05) health utility decrements were for stroke (event, −0.109; history, −0.051), amputation (event, −0.092; history, −0.150), congestive heart failure (event, −0.051; history, −0.041), dialysis (event, −0.039), estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m2 (event, −0.043; history, −0.025), angina (history, −0.028), and myocardial infarction (MI) (event, −0.028). There were smaller effects for laser photocoagulation and eGFR <60 mL/min/1.73 m2. Decrements for dialysis history, angina event, MI history, revascularization event, revascularization history, laser photocoagulation event, and hypoglycemia were not significant (P ≥ 0.05).

CONCLUSIONS

With use of a large study sample and a longitudinal design, our estimated health utility scores are expected to be largely unbiased. Estimates can be used to describe the health utility impact of diabetes complications, improve cost-effectiveness models, and inform diabetes policies.

Published: December 2020

Contrast induced nephropathy (CIN) is the most common cause of iatrogenic in-hospital kidney dysfunction with high morbidity and mortality. In our 5-year prospective study, we evaluated the role of 16-hour post-procedural continuous veno-venous hemodiafilteration in a 132 patient with high risk Mehran integer index for CIN who had to be subjected to coronary arteriography including primary one. All patients had eGFR < 40 ml/minute and 23 (17.4%) of whom were < 20%. The results showed stable kidney disease post-contrast with no significant local or systemic complications in both males and females. In-conclusion; we advocate its use to protect high-risk patients from CIN.

Introduction: Composite resins are materials that have in their organic matrix different components that can change their initial state after the expiration date established by the manufacturer. Objective: to evaluate in vitro the possible color change of two composite resins used during and after the period of validity. For this, composite resins LLis color A1 and A2 will be selected, inside and outside the shelf life. Methods: For each resin (4 groups) were made ten discs (n = 10), of 5mm x 2mm. The analyzes were carried out in an environment with lighting and temperature controlled by a single examiner. Results: The spectrophotometric test was performed using the Vita EasyShade® device in which the values of the Vitta scale and the Cie system L * a * b * were obtained. The values of ΔE were obtained by comparing the specimens of expired and non-expired resins and showed that, regardless of the color tested, the resins did not change color. Conclusion: Regardless of the color, the resins out of the shelf life showed no color difference.

Monoclonal gammopathy of undetermined significance (MGUS) is a clonal plasma cell disorder implicated as a precursor of multiple myeloma (MM), while smoldering multiple myeloma (SMM) is a malignant plasma cell disorder without evidence of a myeloma-defining event(s) (MDE). This is a review article of both disorders outlining their current definition and management according to the current standard of care. We focus on the pathogenesis of MM and the role of MGUS and SMM in the development of active MM. MGUS is a benign disorder and, subsequently, is followed by observation. In contrast, for SMM, although the current standard of care is “watch and wait”, this paper will explore the circumstances in which treatment should be considered to prevent MDE.

The aim of experiment was to analyse the structural transformations and changes in mechanical properties of K720 steel during heat treatment (quenching). Three types of cooling medium were selected. The heating parameters and subsequent delays at the recrystallisation temperature were the same for all samples and were observed in a laboratory furnace. Water with the highest cooling capacity was selected as the benchmark cooling medium. Subsequently, the hardening oil TK – 46 was used. Sunflower oil was selected as the last quenching medium, which can be considered an ecological replacement of quenching oil with possibility of biological disposal. The microstructure and microhardness of individual samples were subjected to a metallographic evaluation and evaluated according to ČSN EN ISO 6507, respectively. The impact toughness analysis was performed according to the ČSN EN ISO 148-1 and a three-point bending test was performed according to ČSN EN ISO 7438. This test specifies a method for determining the ability of metallic materials to undergo plastic deformation in bending. The bend test includes subjection of round, square, rectangular or polygonal cross-section to plastic deformation by bending, without changing the direction of loading, until the specified angle of bend is reached.

The common bean (Phaseolus vulgaris L.) has been the subject of a number of studies and has been described by many authors as a legume with low nitrogen fixing potential compared to other legume species. The first objective of this study is to assess the development and growth of P. vulgaris L. var. Djedida and its yield at different developmental stages (vegetative, flowering and fruiting), in the presence and absence of nitrogen fertilizer (Urea 46) in an arid climate and in a soil containing high level of CaCO3 and assimilable phosphorus. The second objective is to carry out a survey on nodulation, number of spores and mycorrhizal infection under these conditions. The results showed that the nitrogen fertilizer amendment is mainly significant (p< 0.0001) for various morphological parameters. Indeed, great improvement was observed on the majority of the morphological parameters with considerable percentages. However, no significant effect was reported for the roots length. In addition, a negligible number of nodules were obtained in the plot without fertilization and no significant effect on the number of spores was recorded. Furthermore, the effect of fertilization on the arbuscular intensity (a%, A%) and on mycorrhizal colonization (M%, m%) of the roots was found to be significant. The soil in the arid region of Biskra showed significant mycorrhizogenic potential, although the conditions in this region were not very favorable for their development, which could constitute an effective biological resource to improve the tolerance of host plants to biotic and abiotic constraints.

Communication plays a very critical role in ensuring that hotel staffs render better and efficient service through a mutual sense for job satisfaction, career growth and service performance. This study, therefore, aims at evaluating the relationship between the strategies of communication and performance of hotels in Port Harcourt, Rivers State, Nigeria. Both primary and secondary data were sourced. Further, quasi-experimental research design was used for this study, while 180 questionnaires were distributed to sampled hotel staffs within the study area. This was achieved using a random sampling technique for questionnaire administration. It was hypothesised that there is no significant relationship between communication strategy and hotel performance in Port Harcourt. Meanwhile, Spearman rank order correlation coefficient with the aid of Statistical Package for Social Sciences (SPSS) was used to test and analyse the data collected. The output of the analysis reveals a positive correlation between communication strategy and hotel performance. Therefore, the alternate hypothesis was accepted and the null discarded. It was, therefore, fit to conclude that effective communication strategy will enhance the level of competitiveness and performance of the hotels in a general perspective.

Recent research indicates that more and more often tourists use the Madeira Natural Park (MNP) area to develop their physical activity, through mountain hiking and Levada walks. This study aims at identifying tourists’ characteristics and to understand how visitors live their experience. A survey was carried out at the end of two different activities and the sample was divided into two groups (G1: Levada Walks in the Laurissilva; G2: Walks outside the Laurissilva). The data was collected immediately after the activity ended (total: 293; male: 124; female: 169) and people were asked about: 1. Information available at the start of the activity; 2. Interaction and attention demand; 3. Natural area visited. The data indicates that the Madeira tourists have higher education, many are students and teachers, the majority being European. Our tourists are well informed about the natural environment and more than 90% agreed that it was ideal for aesthetic enjoyment and inspiring exploration. Our findings can help the tourist agents to improve their products, encourage the agencies to attract new markets outside Europe and can work as a basis for providing more guidance in the MNP, promoting a higher ‘flow experience’.

This paper reports a research study that investigated buckling of stiffened rectangular isotropic plates elastically restrained along all the edges (CCCC) under uniaxial in-plane load, using the work principle approach. The stiffeners were assumed to be rigidly connected to the plate. Analyses for critical buckling of stiffened plates were carried out by varying parameters, such as the number of stiffeners, stiffness properties and aspect ratios. The study involved a theoretical derivation of a peculiar shape function by applying the boundary conditions of the plate on Taylor Maclaurin’s displacement function and substituted on buckling equation derived to obtain buckling solutions. The present solutions were validated using a trigonometric function in the energy method from previous works. Coefficients, K, were compared for various numbers of stiffeners and the maximum percentage difference obtained within the range of aspect ratios of 1.0 to 2.0 is shown in Figs 2 - 7. A number of numerical examples were presented to demonstrate the accuracy and convergence of the current solutions.

Published: December 2020

In Australia and others developed countries, concerns about global warming have increased, and these concerns influence the use of refrigerants as working fluids in mechanical vapour compression refrigeration systems. One of the most important aspects of refrigerant selection is to reduce its impact on the environment and the ozone layer. This paper provides a comprehensive review of various theoretical and experimental studies which have been carried out on air conditioning and refrigeration applications to investigate the effect of refrigerants on the environment. The analysis in this paper reveals that alternative refrigerants are the most suitable working fluids that can be used in refrigeration systems to meet the needs of the environment. This study also suggests that natural types of refrigerants such as water, carbon dioxide, and hydrocarbon will play a significant role in protecting the environment and providing alternative friendly refrigerants to be used in refrigeration and air conditioning systems.

Published: December 2020

An unsteady flow of heat and species transport through a porous medium in an infinite movable vertical permeable flat surface is considered. The hydromagnetic chemical reactive fluid flow is stimulated by the thermal and solutant convection, and propelled by the movement of the surface. The formulated nonlinear flow equations in time space are solved analytically by asymptotic expansions to obtain solutions for the flow momentum, energy and chemical concentration for various thermo-physical parameters. The existence of flow characteristic is defined with the assistance of the flow parameters. In the study, the impact of some pertinent flow terms is reported and discussed. The study revealed that the species boundary layer increases with a generative chemical reaction and decreases with a destructive chemical reaction. Also, arise in the generative species reaction term reduces the flow momentum for the cooling surface. The impact of other flow governing parameters is displayed graphically as well as the fluid wall friction, wall energy and species gradients. The results of this study are important in chemical thermal engineering for monitoring processes to avoid solution blow up.

Published: December 2020

The creep test is one of the important approaches to determining some mechanical properties of composite materials. This study was carried out to investigate the creep behaviour of an epoxy composite material that was reinforced with Y2O3 powder at weight ratios of 2%, 7%, 12%, 17% and 22%. Each volume ratio was subjected to five loads over the range of 1N to5N at a constant temperature of 16 ± 2°C. In this work, creep behaviour, stress and elasticity modulus were studied through experimental and numerical analyses. Results showed that increasing the weight ratio of Y2O3 powder enhanced creep characteristics.
