Ink splitting in gravure printing: localization of the transition from dots to fingers

For the gravure printing process, ink transfer from the printing cylinder to the substrate is studied in the parameter regime at the very border between point and lamella splitting. In this parameter regime, ink drop deposition from adjacent gravure cells is such that, by capillary and wetting forces in the nip, the drops are at the onset of mutual coalescence. This process offers the possibility to deposit an ultimately thin and closed ink film. We discuss the particular type of pattern and defect formation in the printed layer and show that these apparently stochastic patterns have reproducible features. We claim that, besides the two known regimes of point and lamella splitting, at least one additional ink transfer regime is possible, with well-controllable wetting and ink flow dynamics. A classification scheme is proposed, based on raster-scale pattern phenomenology, by which the printer can recognize and distinguish this third regime by optical inspection of the printed product. Gaining control over this regime offers novel opportunities for gravure printing in thin-film related applications such as printed electronics and package printing.
Association of serum zinc and vitamin E levels with Acne vulgarisin Bangladeshi acne patients

The serum level of zinc and vitamin E were measured to understand the association of various nutrients on acne pathogenesis. Both zinc and vitamin E are antioxidants used as a supplement in acne treatment. However, their effect and status in acne patients are not fully understood. This study included 48 acne patients and 48 sex- and age-matched healthy controls. The zinc and vitamin E concentration was measured in the serum by flame atomic absorption spectroscopy (AAS) and HPLC methods. Compared to the healthy control, a significant deficiency of serum vitamin E level in acne patients (p<0.001) was found, although the patients were not deficient in serum zinc level (p=0.22). In addition, female acne patients had a slightly lower zinc level than male patients (p=0.06). The low serum vitamin E level suggests that supplementation of vitamin E might be helpful in acne treatment. However, further studies are required to understand the dose and mechanism of vitamin E supplements in acne treatment. J. Bangladesh Acad. Sci. 45(1); 49-58: June 2021
Ammonium Excess Leads to Ca Restrictions, Morphological Changes, and Nutritional Imbalances in Tomato Plants, Which Can Be Monitored by the N/Ca Ratio

Both nitrogen and calcium fertilization management are vital for crops, where an imbalance of these elements can cause both physiological and yield problems. It has been proposed that nitrogen absorption, particularly ammonium, is in part dependent on calcium supply. Moreover, the balance between these two nutrients could be a key indicator of plant growth in some species. Tomato, one of the most cultivated crops worldwide, can also be widely affected by nutritional imbalance. Using large amounts of N fertilizers could lead to an imbalance with other nutrients and, thus, detrimental effects in terms of plant development and yield. Here we show that ammonium excess has a negative impact on plant development and results in calcium deficiency. Moreover, a deficit in calcium nutrition not only affects calcium concentration but also leads to a restriction in N uptake and reduced N concentration in the plant. These effects were evident at the seedling stage and also during flowering/fruit set. Using PCA analysis, we integrated both phenotypic and nutritional imbalances in seedlings and grown plants. Interestingly, the Ca/N ratio appears to be a key indicator to monitor appropriate N and calcium nutrition and more importantly the balance between both. Maintaining this balance could be an essential element for tomato crop production.
A SmartPLS Visiting to Knowledge Retention: A Study Among SMEs in Peninsular Malaysia

Maintaining knowledgeable employees is a challenge for most organizations. Many SMEs have recently suffered from the loss of knowledge as a result of employees leaving the organization. When employees leave, the organization may suffer from the loss of knowledge, impact on overall productivity, and the organization’s profit. Much previous research has been conducted on succession planning and knowledge management, but there has been a lack of studies concentrated on succession planning and its impact on knowledge retention. Thus, the aim of this study is to determine the direct impact of succession planning initiatives on knowledge retention among SMEs in Peninsular Malaysia. Quantitative methods and survey questionnaires were used to target employees working in SMEs and holding a managerial position in the services and manufacturing sector. 81 respondents participated in this study and the SmartPLS 3.0 software was used to analyse the findings. Empirical findings show that there are two variables related to succession planning initiatives which are management support and organizational culture that contributed significantly towards knowledge retention. Implications of the study are also discussed. Received: 17 January 2021 / Accepted: 20 May 2021 / Published: 8 July 2021
Co-creative tourism experiences – a conceptual framework and its application to food & wine tourism

ABSTRACT Travel has become a synonym of living memorable and enjoyable experiences. Co-creation centralizes tourists’ role in the creation of value that results from the interaction with other destination stakeholders and the physical environment. Within the wider destination experience, the growing interest tourists show regarding the food and wine experience is notorious, due to its distinctive, multisensory and engaging nature. However, conceptual and empirical studies on co-creation of experiences in food and wine contexts are still scarce. To address this gap, this conceptual study presents an integrative literature review of 118 articles focusing on co-creation in tourism experiences, aiming at understanding what conceptual and empirical studies have been developed in the field, and identifying the most representative dimensions of tourism co-creation, both in general tourism experience and in food and wine experiences, in particular. Based on study findings, a critical analysis is presented along with a novel framework and definition of co-creative tourism experiences, with particular relevance to food and wine tourism. Key dimensions of co-creation in food and wine experiences, namely interaction, engagement, participation and personalization, are identified as relevant for promoting involving and immersive experiences. Theoretical and managerial contributions to destination managers and local stakeholders are also discussed.
Low Energy Recoil Simulations in MgO, LiNbO3, and LiTaO3 Using Ab Initio Molecular Dynamics

Ab initio molecular dynamics (AIMD) was utilized to test a series of materials, MgO, LiNbO3 , and LiTaO3 , to determine defect structures produced due to low energy recoil events . The kinetic energy required to displace an atom from its lattice site, the threshold displacement energy, was calculated for an array of directions in each material, based on symmetry and complexity of the structure. MgO having a simple rock salt structure provided a model material for demonstrating computational techniques used later on LiTaO3 and LiNbO3 . The minimum values for displacing an atom were at 25.5 eV for O and 29.5 eV for Mg. For LiNbO3 and LiTaO3 , the minimum energy for displacing an atom was 6 eV for Li in LiTaO3 and 14 eV for Li in LiNbO3 . Average values for threshold displacement energies agreed well with those used in calculations, but they have not yet been accurately measured experimentally. Additionally, the defect structures and properties were identified and reported as a result of the simulations. The high defect formation energy reported for cation vacancies means that they are unstable in the structure and will either recombine, form defect complexes, or migrate to defect sinks in the material.
Exploring the Association Between Prostate Cancer Diagnosis per se and use of GnRH Agonists and Diabetes Control in Men with type 2 Diabetes Mellitus: A Nationwide, Population-Based Cohort Study

Background: Gonadotropin Releasing Hormones agonists (GnRH), which are first line treatment for metastatic prostate cancer (PCa), increase risk of type 2 diabetes mellitus (T2DM). This study aims to quantify the association of use of GnRH with diabetes control in PCa men with T2DM.Methods: Nationwide population-based cohort study in the Swedish National Diabetes Register and Prostate Cancer data Base Sweden 4.1, on the association between GnRH and diabetes control in T2DM men with PCa by comparing T2DM men with PCa vs. without PCa, as well as comparing T2DM men with PCa on or not on GnRH. The primary exposure was use of GnRH. Worsening diabetes control was the primary outcome, defined as: 1) increase of HbA1c to 58 mmol/mol or higher; 2) HbA1c increase by 10 mmol/mol or more; 3) Start of antidiabetic drugs or switch to insulin; 4) combine all definitions above. Cox proportional hazards regression was used to analyze the association. Results: There were 5,714 T2DM men with PCa of whom 692 were on GnRH and 28,445 PCa-free men with T2DM with similar baseline characteristics. Diabetes control was worse in men with GnRH vs. PCa-free men (HR: 1.24, 95% CI: 1.13-1.34) as well as compared with PCa men without GnRH (HR:1.58, 95% CI: 1.39-1.80). Conclusion: Use of GnRH in T2DM men with PCa was associated with worse glycemic control. The findings highlight the need to closely monitor diabetes control in men with T2DM and PCa starting GnRH agonists and to limit the duration of their use when possible.

Progress in Health Goals and Treatment Recommendations of Diabetes Mellitus Patients

The current guidelines for improving the care of people with type 2 diabetes (diabetes mellitus) suggest that doctors should also inform patients about the necessity of achieving health-related diabetes goals. A patient´s ability to successfully achieve health-related goals and treatment recommendations could improve their health and decrease the risk of diabetes-related complications. The present study aims to explore if the selected goal/recommendation characteristics (motivation, self-efficacy, effort, and challenge) support the progress in health-related goals and recommendations. A study was performed with 120 patients diagnosed with type 2 diabetes from the Centre for Diabetes Treatment at the L. Pasteur University Hospital in Košice, Slovakia. The participants responded to questions about health goals, treatment recommendations and obstacles with items assessing motivation, effort, challenges, self-efficacy, and progress. The results showed that patients with diabetes were more likely to make successful progress when health-goals were autonomous and recommendations were autonomous or controlled motivated. There was a significant effect of patients’ effort and efficacy on progress in both goals and recommendations. With increasing years of diabetes, the recommendations and goals’ autonomous motivation significantly decreased while recommendation effort increased. Goals and recommendation challenge did not predict progress. The results suggest that interventions should focus on encouraging want-to motivation, self-efficacy and professionals evaluate patients’ effort.
Portuguese translation and cultural adaptation of the Music in Dementia Assessment Scales (MiDAS)

ABSTRACT Introduction Music in Dementia Assessment Scales (MiDAS) is an observational, dementia-specific, visual analogue scale, developed to measure musical experiences of patients with dementia (PwD). It was derived from qualitative data from focus groups and interviews with PwD, carers, care home staff, and music therapists. Since its publication, there has been great interest in using MiDAS in several European countries, including Portugal. However, no adaptation to Portuguese language and culture is yet available. In this manuscript, we aim to describe the process of translation and cultural adaptation of MiDAS to European Portuguese, presenting the final MiDAS-PT version. Method We have followed a rigorous 10-step approach, consisting of: a preparation stage; elaboration of two forward translations; synthesis of the latter versions; back-translation by a bilingual professional translator; revision of that version by the original author of MiDAS; harmonization with other versions of MiDAS in different languages; testing and debriefing of the final version with volunteer health professionals; consensus meetings; proofreading; and, finally, the reporting of the process. Results No major changes have been made to the actual content text of MiDAS. Some minor adjustments were made to the wording, and additional instruction details were added in order to increase clarity and adequacy in the Portuguese setting. Discussion Overall, Portuguese health professionals considered the instrument to be user-friendly and intuitive in terms of content, structure and layout. To allow the use of MiDAS-PT for research and clinical purposes, the next step will be a study of its psychometric properties.
Depletion-mode vertical Ga2O3 trench MOSFETs fabricated using Ga2O3 homoepitaxial films grown by halide vapor phase epitaxy

We developed depletion-mode vertical Ga2O3 trench metal–oxide–semiconductor field-effect transistors by using n+ contact and n− drift layers. These epilayers were grown on an n+ (001) Ga2O3 single-crystal substrate by halide vapor phase epitaxy. Cu and HfO2 were used for the gate metal and dielectric film, respectively. The mesa width and gate length were approximately 2 and 1 µm, respectively. The devices showed good DC characteristics, with a specific on-resistance of 3.7 mΩ cm2 and clear current modulation. An on–off ratio of approximately 103 was obtained.
Technical and Economic Feasibility Study for Implementing a Novel Mooring-Assisting Methodology in Offloading Operations Using Autonomous Unmanned Aerial Vehicles

As oil and gas exploration goes toward deeper fields in the Brazilian industry scenario, offloading operations emerge as the most viable option to drain production. However, these operations demand expensive resources, such as shuttle tankers and support boats; operational risks, which despite being managed, limited, and mitigated to be as low as reasonably possible, are still present in some stages (i.e., ship’s approximation to the oil rig, mooring, hose connection, and so forth); and environment limiting parameters (i.e., wave height, surface-current direction, wind speed and direction, and so forth). Therefore, in this paper, we propose using unmanned aerial vehicles (UAVs) in an autonomous mode to carry out the messenger line from the shuttle tanker to the floating, production, storage, and offloading (FPSO) unit or the floating storage and offloading unit (FSO) instead of line-handling (LH) boats (for conventional operations that use those resources) or the messenger-cable-launching guns (for dynamic positioning operations). This represents a viable alternative solution to reducing costs and risks in these tasks and a possibility to eliminate some meteorologic and oceanographic limiting conditions to operations, because the UAV will be susceptible only to wind conditions, and not to sea and visibility conditions, like LHs are. We present the simulated results of the proposed methodology using a robotic operating system (ROS) and the economic gain [derived from cash-flow-cost reducing of operations, payoff time of the investment, net present value (NPV), and internal rate of return] of applying this technology, evaluating its use in a realistic scenario based on a real deepwater oil field in Brazil. The developed controller behaves very well, and simulations showed robust results. In addition, the economic study presents the proposal’s attractiveness.

The sampling technique used was non-probability sampling, namely the purposive sampling technique with 80 respondents. The data analysis technique used is the Structural Equation model with SmartPLS. The results of this study indicate that digital payments and sales promotions have a simultaneous effect on purchasing decisions. Partially digital payments and sales promotions have a significant effect on purchasing decisions at the Binus branch of Haus drinks.
Determinants of High-tech Export in CEE and CIS Countries

Any government strives to stimulate export activity in high-tech sectors of its economy. Surprisingly, there are few empirical papers on the determinants of high-tech export to date. This study analyses the economies of Central and Eastern Europe (CEE) and the Commonwealth of Independent States (CIS) due to the differences they experienced in the transition period. To this end, we used the Balassa index, which is based on the concept of revealed comparative advantages. The research examines 73 groups of products from the automotive, chemical, mechanical engineering, electronics and electrical engineering industries in 27 countries from 1995 to 2018. Principal component analysis helped generate an indicator of comparative advantage of hightech industries for each country in each year. It is revealed that CEE countries, as well as the Baltic countries, have achieved significant success in the development of high-tech sectors of the economy, while the CIS countries have shown practically no progress in this direction. The article tests hypotheses on the impact of resources, foreign trade, macroeconomy and innovation on export activity in the country. The following factors stimulate the export growth in high-tech industries of the studied countries: level of wages and resource prices, openness of the economy to foreign trade; tax rate; unemployment rate; quality of human capital. We did not find empirical evidence of the positive impact of inflation, inflows of direct foreign investment, and the level of research and development (R&D) costs on the volume of high-tech export of the examined economies.
Globalization, FDI and Trade in Case Study of Pakistan: An Empirical Analysis

Globalization is a complex phenomenon that has many national or international implications, as well as various impacts on the national economy and the world economy in general. The process of national economic globalization is clearly influenced by economic performance, foreign trade, financial development and its ability to attract foreign investment. Foreign capital has played a key role in the development of such a state in Pakistan. The current study used the time series data and the data range form 1981-2017. The variables are Globalization, foreign direct investment and trade. study applied ADF unit root test for stationary of these variables. First the unit root test applies at the level the variables are not stationary then apply at first difference so study applied ADF unit root test for stationary. The result shows that all variables are stationary at first difference. However, all variables are not stationary at level. the application of Johansen co-integration test appropriate applied for the purpose of association between variables. Finally, the study applied Vector Error Correction Model (VECM) for the purpose of long run analysis of the study. Johansen co-integration test concluded that globalization have positive impact on FDI and Trade. (VECM) model shows that the Globalization, FDI and Trade have long run relationship.
Topological investigation of junction flow between cylinder and flat plate

The paper presents a numerical investigation on the junction flow occurring at the intersection between a wall and a protruding circular cylinder. Simulations of flow for Reynolds number (Re) in the range [125 - 20000] have been carried out using OpenFOAM, an open source CFD tool. Plots of stream tracers have been used to qualitatively characterize the flow topology as either attachment or separation based on the type of singular points, classified as nodes and saddle points. Quantitative variations of momentum flux have been applied to identify a key mechanism for the transition of topology using the relative momentum strength of the incoming and reverse flow. Effect of a thinner boundary layer has been assessed by (i) imposing a reduced wall shear stress, and (ii) increasing the Reynolds number. Features of a typical unsteady flow, in the transition regime, at Re = 20000 have been predicted using Large Eddy Simulation (LES) with a one-equation eddy viscosity sub-grid scale model. Description of the time evolution of the topology at Re = 20000 has been able to validate the one-equation model in OpenFoam as well as to further validate the key mechanism identified for topology transition.
