Published: January 2022

The increasing role of potato breeding in the country’s food security system calls for additional investments into maintenance and technological reconstruction of the branch on the basis of scientifically proven methods and approaches to defining the optimal potato production volumes, its processing and storage to avoid surplus stock, unnecessary losses and inefficient investment resource use at all stages of agricultural and food chain. The aim of the research is to substantiate the conceptual investment model into the development of potato breeding in Ukraine on the basis of estimating the optimal structure of balance between potato production and consumption, as well as efficient combination of the volumes of fresh and processed produce to ensure the competitive potato market parameters in the modern market environment. The object of the research is the process of formation and increase of added value in the agricultural chain through application of optimal parameters of the balance between potato production and consumption. The methods of the research are based on the system analysis law, which enable to substantiate competitive parameters of the potato breeding branch in Ukraine in the changing economic environment, thus to reduce unnecessary losses in the “production-processing-delivery-sale-consumption” chain. Incorporation of the developed optimization model of the balance between potato production and consumption according to the criterion of minimization of potato rest at the end of the year enabled to discover its extreme surplus of 2,4 mln. tons at the beginning of the 2020 year, which was not balanced by consumption demand. The inefficient distribution of the gross domestic potato stock in Ukraine made it possible to draw a conclusion about the need to reduce its surplus production by 17,5% and redirect the main investments into the development of potato processing industry, improvement of its export power and extension of foreign markets for selling Ukrainian potato ready and intermediate products, with further possibility of selling raw potatoes of ensured required quality. In this context the authors proposed the conceptual model of investment into potato breeding in Ukraine proceeding from the optimal balance between potato production and consumption by 2027 year that enables the achievement of strategic effect under the conditions of the global competition.

Authors: Cachay Lidia Margot Tapia , Couto Gualter , Pimentel Pedro , Castanho Rui Alexandre
Published: January 2022

Currently, having a transparent and orderly public institution is related to the public policy of modernization of the state, which is not easy because it requires managers who have the will to implement an internal control system that allows the efficiency and effectiveness of the acts of the entities. The internal control in recent years has greater relevance seeking that the state entities are strengthened through new processes and changes of actions that allow transparency and achieve the objectives set and have an efficient management with a level of security of their administrative acts. The objective of this research is to study the simplification of actions and administrative transformations in public management through internal control. The methodology used for the literature review was descriptive, a search was made through the Scopus database, obtaining general data of 24 records, a not very significant number for the topic addressed, which has been subjected to bibliometric analysis that allowed to determine that the growth of publications from 1977 to 2020 has had an insignificant growth, having been accentuated in 2 publications from 2019 to 2020, likewise the greatest number of researches have been carried out in undefined countries, followed by Portugal, United Kingdom and United States, being the article the publication medium that has the greatest significance and the area that stands out most in publications is the social sciences followed by the economic sciences. Likewise, the Vos viewer was used to obtain the study map and the heat map of the Internal Control and Public Management theme. From the analysis, the theories related to the paradigms of internal control and public management have been analyzed, which will lead us to understand the changes or actions that public entities have or have had.
The Financial – Economic Factors in the Strategic Planning of European Borderlands: Envisioning the So-Desired Sustainable Development
Authors: Castanho Rui Alexandre , Garrido Velarde Jacinto
Published: January 2022

In Europe, there are a considerable number of borderlands involving various Cross-Border Cooperation (CBC) projects, plans, and strategies. It is a well-known fact that these border synergies are perceived as very intricate processes. Consequently, research projects that focus on different variables, factors, and perspectives that could affect the success or failure of the common border projects are essential to achieve consistent regional sustainability. In fact, we believe there is a gap on the perception and implementation of some of the critical factors for territorial success in borderlands by the regional main actors. Thereby, this study through the use of exploratory tools as top-to-bottom questionnaires examines the border cooperation of eleven CBC projects (twenty-one European cities) focusing on the financial-economic theme. Besides, the research permits us to recognize and isolate the two main decisive factors to consider from a financial-economic: (i) Strong territorial strategy; (ii) Access to European funds. Moreover, this study shows that the CBC could be used as a catalyst for creating job opportunities in these regions.

Published: January 2022

The Corporate Social Responsibility (CSR) literature has advanced beyond its long-standing emphasis on a firm's financial performance to include its social impact. However, it has fallen short of offering insight into how effective CSR is in the event of a disaster. This study investigated the community's perception of CSR in wetland farmers communities after flood disasters. Data were from 49 farmer groups in South Kalimantan Province, Indonesia. The research hypotheses were drawn: Perceived benefits of CSR initiatives affect farming community resilience, farming community wellbeing, and perceived competence of wetland farmers; Community resilience affects community wellbeing; Community wellbeing and community resilience affect perceived competence of farmers. The structural equation modeling (SEM) analysis showed that CSR initiatives positively affected community resilience and community wellbeing but had no effect on the perceived competence of farmers; Community resilience had a positive effect on community wellbeing. However, both community wellbeing and resilience did not affect perceived competence. This study sheds light on the complex link between the community and the individual. Triple bottom line and community psychology theories were applied, and this study contributes to the social impact of CSR by focusing on both community and individual, especially in the face of natural disasters in wetlands.
Determinants of Knowledge Transfer in Egocentric Networks. Comparative Analysis of Professions
Authors: Fryczyńska Marzena
Published: January 2022

This paper investigates determinants of knowledge transfer in egocentric networks of knowledge recipient and knowledge provider, what is crucial to knowledge management in organisations. Knowledge transfer is assumed to depend on knowledge work, networking competence, and the subject’s profession: teacher, Information Technology (IT) professional, or physician. The paper reports result of a quantitative study among samples of mentioned professionalists. Regression models testing, including mediation and moderation, were performed. The findings indicate that knowledge transfer in the egocentric network of the knowledge recipient increases along with knowledge work, but only when it is mediated by networking competence. Analyses in each profession support a partial mediation in the case of IT professionals and teachers. Knowledge transfer in egocentric network of the knowledge provider increases along with knowledge work of the provider. In the case of physicians, knowledge transfer in the providers’ and recipients’ knowledge networks is affected neither by knowledge work nor by networking competence.

Byron’s Spanish Afterlives: Emilio Castelar’s
Vida de Lord Byron
Authors: CALZADA SARA MEDINA
Published: January 2022

This article examines Emilio Castelar’s
Vida de Lord Byron
(1873), the first Spanish biography of Byron. Borrowing most information from Moore’s and, especially, Lescure’s biographies of the poet, Castelar provides an apologetic and over-romantic portrait of Byron, in which he tries to reconstruct his private life and inner self, depicting him as a tragic hero who, despite his excesses, should be recognised as a universal genius. Castelar’s biography, which became an immediate success, illustrates the keen interest that Byron still aroused in Spain in the late nineteenth century and it deserves to be considered in the study of Spanish Byronism, a cultural phenomenon that includes but should not be limited to the literary reception of his poetry.
Hero or Dandy? Gender Identity, Politics, and Dialogism in Byron’s
Sardanapalus
Authors: POOLE GABRIELE
Published: January 2022

Starting with an analysis of the mirror scene in
Sardanapalus
as a symbolically dense representation of a series of crucial issues in Byron’s works, this article examines the ways in which the play was used by the author to challenge and interrogate two of his stereotypical, widely accepted public images, ‘Byron as a Byronic hero’ and ‘Byron as an effeminate dandy’, by proposing an alternative figure that combines traits from both stereotypes. Issues of effeminacy, masculinity, and homosexuality will be discussed in relation to dialogism and politics, linking Byron’s multifaceted drama to wider aesthetic, performative and political concerns.
The Distribution of Iron over the Surface of 21 Com
Authors: Monier Richard
Published: January 2022

Comparison of high dispersion LWP spectra obtained in 24 hr of monitoring of 21 Com with IUE in April 1991 reveals variations of low excitation Fe ii lines at phase 0.65 of the rotational period (FUV minimum flux) compared to phase 0.18 (FUV maximum flux). All 10 Fe ii lines of UV Multiplets 1 and 62 are consistently stronger at phase 0.65, which shows that the FUV flux minimum can be partially explained to an increase of the disk averaged iron abundance. In contrast, comparison of optical high resolution high signal-to-noise ELODIE spectra of 21 Com taken in 2004 April and separated by about half of the 2 days rotational period, reveals no significant variations of the Fe ii and Fe i lines. The lines monitored in the mid UV are strong low-lying transitions which are probably more sensitive to small abundance gradients over the surface of 21 Com.

Published: January 2022

Under the global climatic changes and anthropogenic impacts on the environment, information about characteristics and specific features of soils in remote regions as Antarctica is valuable and could be used as references. This study focuses on the analyses of original data about the physico-chemical composition and micromorphological structure of Cryosols, collected in 2019 from the sampling area of the Bulgarian Antarctic Base “St. Kl. Ohridski” located on Livingston Island, Antarctica. The studied Cryosols are moderately acidic with slow and incomplete transformation of organic residues. The organic carbon content is low, except for soils formed under the influence of an ornithogenic factor. The mezo- and micromorphological observations show a predominance of the mineral phase, weakly affected by weathering processes. Many soil pores and voids are observed, which facilitates water-air and intra-soil exchange during the short Antarctic summer. The analyses showed an evidence for the connection of the processes of soil formation of Cryosols in the region with the pulsating degradation of the glaciers.

Published: January 2022

This article reports a case of a 65-year-old woman with recalcitrant recurrent epiretinal membrane (ERM) treated with revision vitrectomy and membrane peeling followed by 12 weekly intravitreal methotrexate injections. Visual acuity and central macular thickness significantly improved, and no ERM recurrence developed 7 months after surgery. This case represents the first documented use of methotrexate to treat surgically resistant ERM reproliferation and indicates a potential for its use in cases that do not respond to standard treatment.

Risk and Prevention of Retinal Detachments in Patients with Stickler Syndrome
Authors: Naravane Ameay V. , Belin Peter J. , Pierce Benjamin , Quiram Polly A.
Published: January 2022

BACKGROUND AND OBJECTIVE:

To report the impact of prophylactic laser retinopexy in the prevention of retinal detachments (RDs) in patients with Stickler syndrome.

PATIENTS AND METHODS:

This was a retrospective, comparative case series of patients with Stickler syndrome from the year 2000 to 2019. We compared the rate of RDs between individuals who did and did not receive prophylactic laser therapy. In patients with an RD, we compared the rate of RD in the fellow eye with and without prophylactic laser treatment.

RESULTS:

A total of 95 eyes were identified. Fifty-four percent of the overall population was female. The RD rate was 26.7% among eyes without previous prophylactic laser retinopexy and 4.6% among eyes with previous prophylactic laser retinopexy. A Cox proportional model revealed that laser prophylaxis treatment had a statistically significant effect on the risk of RD or retinal tear during the 25-year survival period from birth (
P
= .034). Eyes receiving treatment were 70% less likely to experience RD or retinal tear (hazard ratio, 0.297; 95% CI, 0.097 to 0.913).

CONCLUSIONS:

This study's results suggest a potential role for prophylactic laser retinopexy in the prevention of rhegmatogenous RD among patients with a clinical diagnosis of Stickler syndrome.

Authors: Li Jingjing ,   School of Mathematical Sciences, Suzhou University of Science and Technology, Suzhou 215009, China, Huang Zhigang
Published: January 2022

In this paper, we mainly investigate the radial distribution of Julia sets of difference operators of entire solutions of complex differential equation $ F(z)f^{n}(z)+P(z, f) = 0 $, where $ F(z) $ is a transcendental entire function and $ P(z, f) $ is a differential polynomial in $ f $ and its derivatives. We obtain that the set of common limiting directions of Julia sets of non-trivial entire solutions, their shifts have a definite range of measure. Moreover, an estimate of lower bound of measure of the set of limiting directions of Jackson difference operators of non-trivial entire solutions is given.

In this paper, we introduce an ordered implicit relation. We present some examples for the illustration of the ordered implicit relation. We investigate conditions for the existence of the fixed points of an implicit contraction. We obtain some fixed point theorems in the cone $ b $-metric spaces and hence answer a fixed-point problem. We present several examples and consequences to explain the obtained theorems. We solve an homotopy problem and show existence of solution to a Urysohn Integral Equation as applications of the obtained fixed point theorem.

The neuropsychiatric systemic lupus erythematosus (NPSLE), a severe disease that can damage the heart, liver, kidney, and other vital organs, often involves the central nervous system and even leads to death. Magnetic resonance spectroscopy (MRS) is a brain functional imaging technology that can detect the concentration of metabolites in organs and tissues non-invasively. However, the performance of early diagnosis of NPSLE through conventional MRS analysis is still unsatisfactory. In this paper, we propose a novel method based on genetic algorithm (GA) and multi-agent reinforcement learning (MARL) to improve the performance of the NPSLE diagnosis model. Firstly, the proton magnetic resonance spectroscopy ($ ^{1} $H-MRS) data from 23 NPSLE patients and 16 age-matched healthy controls (HC) were standardized before training. Secondly, we adopt MARL by assigning an agent to each feature to select the optimal feature subset. Thirdly, the parameter of SVM is optimized by GA. Our experiment shows that the SVM classifier optimized by feature selection and parameter optimization achieves 94.9% accuracy, 91.3% sensitivity, 100% specificity and 0.87 cross-validation score, which is the best score compared with other state-of-the-art machine learning algorithms. Furthermore, our method is even better than other dimension reduction ones, such as SVM based on principal component analysis (PCA) and variational autoencoder (VAE). By analyzing the metabolites obtained by MRS, we believe that this method can provide a reliable classification result for doctors and can be effectively used for the early diagnosis of this disease.
Fundus Examination in Pediatric Patients Using Indirect Ophthalmoscopy
Authors: Ledoux Danielle M. , Johnson Brandon , Moradi Issac , Zhu-Tam Lily
Published: January 2022

The goal of this chapter is to provide the clinician with an understanding of binocular indirect ophthalmoscopy (BIO) and helpful clinical techniques for success in examining the fundus of the pediatric patient, including scleral depression. The challenging technique to examine the premature infant at risk for retinopathy of prematurity will be explained in detail, including the standard classification of the disease with photos depicting the different location and stages of disease. BIO with the addition of scleral indentation helps the clinician diagnose and locate lesions that may otherwise go undetected, such as retinal holes, tears, or vitreoretinal adhesions. Complete examination of the fundus of a child is no less important than of any other patient who seeks eye care but often requires efficiency and precision (as well as many human arms). Time is a rate limiting aspect when examining children so preparation and experience will lead to success.

Digital Marketing as a Driver of Tourism
Authors: Figueiredo Gabriel Vieira Mendes , Neto João Pinheiro de Barros
Published: January 2022

Brazil has enormous, underexplored tourism potential. To identify how digital marketing can boost tourism, the authors chose to examine the city of Paraty—a touristic microcosm of Brazil. Digital marketing is a low-cost marketing strategy that can reach potential tourists anywhere. Its use by tourism entrepreneurs has proven effective and able to generate significant return on investment. This exploratory study aimed to develop hypotheses. The authors used questionnaires and interviews to assess the perception of local tourism entrepreneurs regarding the affordances and advantages of digital marketing tools, techniques, and strategies. They found that entrepreneurs' adoption of digital marketing brought several benefits, including low investment costs and significant returns. However, the research revealed the need for training, mainly for small entrepreneurs to explore the numerous opportunities of the web in their businesses. Public authorities can also play a more leading role in combining and steering efforts to promote tourism.

Published: January 2022

With the acceleration of the digital transformation and technological upgradation of various industries, in the wake of application of new technologies such as 5G, artificial intelligence, and the internet of things, the demand for data storage, computing, transmission, and applications has greatly increased. Remote working, remote education, and e-commerce on account of the pandemic have led to a drastic increase in data consumption as well. The processing and analysis of massive data requires the construction of an information infrastructure—Internet Data Center (IDC). In the past few years, China's government has been dedicating itself to the task of constructing IDCs in some underdeveloped areas and establishing more detailed regulations. This chapter introduces some basic policies and implications behind this and a mathematical way to quantitatively analyse the investment efficiency of R&D resources in China's different regions. Several recommendations for the government and the society at large have also been outlined in this chapter for improvement in the whole ecosystem for IDCs in China.

To overcome the shortcomings of the standard particle swarm optimization algorithm (PSO), such as premature convergence and low precision, a dynamic multi-swarm PSO with global detection mechanism (DMS-PSO-GD) is proposed. In DMS-PSO-GD, the whole population is divided into two kinds of sub-swarms: several same-sized dynamic sub-swarms and a global sub-swarm. The dynamic sub-swarms achieve information interaction and sharing among themselves through the randomly regrouping strategy. The global sub-swarm evolves independently and learns from the optimal individuals of the dynamic sub-swarm with dominant characteristics. During the evolution process of the population, the variances and average fitness values of dynamic sub-swarms are used for measuring the distribution of the particles, by which the dominant one and the optimal individual can be detected easily. The comparison results among DMS-PSO-GD and other 5 well-known algorithms suggest that it demonstrates superior performance for solving different types of functions.

Published: January 2022

Due to high theoretical specific capacity and abundant reserves, tin selenide-based materials have received tremendous attentions in the fields of lithium-ion batteries. Nevertheless, the huge volume changes during insertion/de-intercalation processes deteriorate the Coulombic Efficiency greatly. In order to solve it, the researchers have made great efforts by means of controlling nanoparticles granularity, carbon coating, ion doping et al. In this study, SnSe/Cu2SnSe3 heterojunction nanocomposites were synthesized by solvo-thermal method. The resulting SnSe/Cu2SnSe3 is a three-dimensional flower-like hierarchical nanostructure composed of nanoscale thin lamellae of a thickness of 8-12 nm. The unique nanostructure could shorten the diffusion path of lithium ions and expedite charge transfer, and therefore enhance the reaction kinetics. Compared with SnSe, the initial Coulombic efficiency of SnSe/Cu2SnSe3 is raised from 59% to 90% as the anode material of lithium-ion batteries.

Massive coal gangue waste delivers environmental disasters in China. Finding an effective, efficient, practical and value-added approach for large-scale disposal of coal gangue waste is very urgent. In this study, thermal treatment approach was conducted on coal gangue waster with the goal to improve its pozzolanic activity so that considerable replacement of Portland cement can be realized. XRD analysis, IR analysis as well as the evaluation on mechanical properties of mortar specimen were carried out to optimize thermal treatment program. The results indicate that coal gangue waste can be efficiently treated at 850°C in less than 30min to obtain pozzolanic activity of 108% at 7 days and 124% at 28 days. And an industrial product also shows similar improvement in pozzolanic activity to the lab results, and indicates the potential for producing eco-efficient cementitious materials.
Effect of Mg/Si Ratio on Hardening Behavior, Microstructure and Properties of Al-Mg-Si Alloys
Authors: Zheng Ya Ya , Long Tao , Li Bing
Published: January 2022

The effects of Mg/Si ratio on precipitation behaviour and properties of Al-Mg-Si alloys were studied by using electrochemical test, corrosion test and transmission electron microscope (TEM). The results show that with the increases of Mg/Si ratio from 0.9 to 1.1, the density of the β" decreases, and the mechanical properties decrease. When the ratio of Mg/Si increases from 1.0 to 1.1, the density y of β" does not increase significantly, but the continuous degree of the MgSi phase decreases significantly. The source of cracks originate from MgSi phase, which reduces the mechanical properties. When the Mg/Si ratio is 0.9, the alloy is in an over-Si state, which results in serious intergranular corrosion (IGC).

A series of luminescence phosphors M0.955Al2 –xGaxSi2O8∶Eu2+ (M=Ca, Sr, Ba, x = 0~1.0) were prepared via solid-state reaction in weak reductive atmosphere. The lattice positions were discussed. It was found that when Ga3+ entered MAl2Si2O8 lattice and substituted Al3+, complete solid solutions formed. The lattice parameters (a, b, c) and unit cell volume of phosphors M 0.955Al2 –xGaxSi2O8: Eu2+ (M=Ca, Sr, Ba, x = 0~1.0) increased linearly, the lattice parameters (α, β,γ) of Ca0.955Al2–xGaxSi2O8∶Eu2+(CAS) decreased linearly and the lattice parameter β of Sr0.955Al2–xGaxSi2O8∶Eu2+(SAS) and Ba0.955Al2–xGaxSi2O8∶Eu2+(BAS) increased linearly as Ga3+ content increased.

Published: January 2022

This paper demonstrates the transport of electron and hole carriers in two distinct hydrogenated amorphous semiconductor materials at different temperatures. Compared to crystalline materials, the amorphous semiconductors differ structurally, optically and electrically, hence the nature of carrier transport through such amorphous materials differ. Materials like hydrogenated amorphous silicon and amorphous IGZO have been used for the study of temperature dependent carrier transport in this paper. Simulation results have been presented to show the variation of free electron and hole concentration, trapped electron and hole concentration with energy at 300K for both the materials. The change in mobility with a change in the Fermi level has been plotted for different temperatures. The effect of temperature on Brownian motion mobility of electrons and holes in hydrogenated amorphous silicon and amorphous IGZO has been demonstrated towards the end of this paper.

Published: January 2022

In recent years, the diffusion of additive manufacturing (AM) or 3D printing (3DP) techniques for polymers have been boosted by the expiration of earlier patents from the last century and the development of low-cost machines. Since these technologies become more widespread, there is a need to assess the capability and accuracy of low-cost machines in terms of dimensional and geometric tolerance. To this aim, this work proposes an innovative reference part for benchmarking layerwise processes that involve the curing of photopolymers. The geometry of the part is conceived to include several classical shapes that are easily measurable for defining the part accuracy in terms of ISO IT grades and GD&T values. Two replicas of the reference part were fabricated by stereolithography (SLA) and digital light processing (DLP) using two machines and related proprietary materials by Sharebot Company. The replicas were printed with a layer thickness of 50 μm for the DLP process and 100 μm for the SLA one. The results of dimensional measurements of the replicas, that were carried out using a Coordinate Measuring Machine (CMM), show that the geometric accuracy of the time-consuming DLP process is slightly better than that of stereolithography.

Carbide tools with mono/multilayer coating such as TiN, TiC, TiAIN, TiB2 and Al2O3 on inserts of WC-Co generated key success for machining of ferrous materials without coolant/lubrication. So far dry machining of aluminium, manufacturing industries such as automobile and aerospace engineering are facing considerable challenges. Exploration of correct cutting tool for machining of aluminium still persists in the present day context. This paper experimentally investigated the affinity and performance of different cutting tool materials available in local tool shopping center along with the diamond coated tool insert prepared and developed in our own HFCVD reactor for machining of aluminium in dry condition. Finally it is revealed that, due to the low chemical affinity, small magnitude of cutting force, chemical inertness and remarkable anti-welding characteristics, diamond coated tool displayed improved performance as compared to other tools.
