An Approach Based on Metadata to Implement Convention over Configuration Decoupled from Framework Logic
Authors: Gomes Everaldo , Guerra Eduardo , Lima Phyllipe , Meirelles Paulo
Published: April 2023

Frameworks are essential for software development, providing code design
and reuse for its users. Well-known Java frameworks and APIs such as
Spring, JUnit, and JPA rely on metadata usage, commonly defined by code
annotations. Those frameworks use the Java Reflection API for consuming
and processing these annotations. Code elements usually have some
similarities and can also have the same annotation. This paper proposes
a model for defining conventions over configuration for annotations
usage decoupled from the metadata reading logic. With this model, if a
convention is present, the framework will consider that the element is
configured by a specific target annotation, even if the code element
does not have the annotation. We implemented this model in the metadata
reading framework Esfinge Metadata API. The model implementation was
evaluated refactoring an existing framework to add support to
conventions using our approach. As a result, it was possible to
introduce the conventions only by adding configurations to the
annotations. The model was further evaluated in an experiment in which
participants implemented the Conventions over Configuration pattern
using the Esfinge Metadata API and Java Reflection API. Based on the
results, approach fulfilled its goal of supporting the definition of
conventions decupled from the framework logic, making the code more
readable and easier to maintain according to the participants
perception.

Published: April 2023

Double perovskites that are lead-free are becoming increasingly popular
for use in a variety of applications such as solid-state lighting,
thermoelectrics, and photovoltaics. In this study, the physical
properties of inorganic double perovskites Rb2NaBiX6 (X= Cl, F, Br, I)
were thoroughly examined using the density functional theory (DFT) based
Wien2K code. Structural parameters were determined using the Murnaghan
equation of state and Chapin’s method, which were found to be in good
agreement with other current results. The research focused on
investigating the mechanical, electronic, optical, and transport
properties of Rb2NaBiF6, Rb2NaBiCl6, Rb2NaBiBr6, and Rb2NaBiI6 double
perovskites for use in optoelectronics and photovoltaic devices. The
calculated indirect band gap values using GGA and LDA approximation were
found to be 4.932, 3.637, 2.972, and 2.002 eV for Rb2NaBiF/Cl/Br/I6,
respectively. Optical properties were analyzed in terms of dielectric
constants, absorption coefficient, refractive index, and reflectivity.
The highest peak absorption was found to occur in the ultraviolet and
visible ranges for all compounds, making them suitable for use in
optoelectronic applications. The electron transport properties were
studied by examining electrical conductivity, thermal conductivity,
Seebeck coefficient, and figure of merit. The resulting ZT values
obtained by the calculations in the temperature range of 100–1200K were
found to be 0.82/0.81 for materials I6/Cl6 and 0.80/0.78 for materials
F/Br. Furthermore, the analysis of transport properties suggested that
the inorganic double perovskites Rb2NaBiX6 (X= Cl, F, Br, I) have p-type
semiconducting characteristics.
Assessment of extractants for soil available potassium determination in the selected soils of Kwara state, Nigeria
Authors:   University of Ilorin, Faculty of Agriculture, Nigeria, Affinnih Kehinde
Published: April 2023

Response of potassium (K) correlated with extracted K using five laboratory methods: neutral N NH4OAc pH 7.0; NH4OAc pH 4.8, 0.01M CaCl2, 1N Hot HNO3 and 0.5N NaHCO3 pH 7.0 by sorghum were determined in four selected soils from twenty locations in Kwara State, Nigeria in the green house to ascertain the ideal procedure for routine analysis. Regression equations were derived for each soil between K uptake by sorghum and level of K applied and, by extrapolation, the A-value, which represented the amount of soil K available as applied K, was determined. The data from the five laboratory methods were correlated with A-value, the zero-level K uptake, and with one another. The results showed that 0.01M CaCl2 only, extracted more K than the A-value, which was greater than the K extracted by the other methods. The data of all methods were, however, significantly correlated (p<0.05) with A-value while zero-level K uptake had a highly significant correlation with data of 0.01M CaCl2 (0.99) and low values with that of the other methods. The neutral normal NH4OAc pH 7.0 correlated relatively high and positively with N NH4OAc pH 4.8, 0.01M CaCl2, and 0.5N NaHCO3 pH 7.0, but negatively (-0.60) with 1N Hot HNO3. However, the neutral N NH4OAc pH 7.0; NH4OAc pH 4.8 correlated relatively higher and positively with one another (0.93) although they both extracted unequal amounts of K. Thus, both could be conveniently handled in the routine work in place of hot 1 N HNO3 for the evaluation of K availability indices for sorghum in the region.

Authors: Tabolli Stefano , Alessandroni Livia , Gaido Jeanette , Sampogna Francesca , Di Pietro Cristina , Abeni Damiano
Published: April 2023

Health-related quality of life (HRQoL) measurements in clinical practice ensure that treatment and evaluations focus on the patient rather than the disease. To verify whether these measurements are also relevant in a minor dermatological disease and whether a generic routine assessment is sufficient to capture different aspects of quality of life, we studied patients affected by nail disorders. The Skindex-29, the 12-item General Health Questionnaire and the 36-item Short Form of the Medical Outcomes Study questionnaires were used. A total of 114 patients were enrolled: 31% men aged 48 +/- 15 years and 69% women aged 49 +/- 14 years (mean +/- SD). The mean values of SF-36 scales in nail disorders were higher than those reported for minor skin diseases, and Skindex-29 values were lower. A duration of disease > or =1 year was associated with higher Skindex-29 scores on the symptom and emotions scales. Patients with onychomycosis have higher values on the Skindex-29 social functioning scale compared with other nail disorders. The use of HRQoL measurements in routine clinical activities allows us to depict how nail disorders affect patients and show how relevant some neglected aspects, such as pain or emotional trauma, are and offers us the opportunity to address these issues in a patient-centred approach to treatment.
Spectrophotometric Analysis of Melanocytic Naevi During Pregnancy
Authors: Wyon Yvonne , Synnerstad Ingrid , Fredrikson Mats , Rosdahl Inger
Published: April 2023

Malignant melanoma is the most common cancer during pregnancy, but it is unknown whether melanocytic naevi in general are activated. A total of 381 melanocytic naevi in 34 Caucasian primigravidae were examined using spectrophotometric intracutaneous analysis (SIAscopy) technology in early pregnancy and prior to delivery. The Siagraphs of each naevus were then compared in order to evaluate changes over time. A total of 163 melanocytic naevi in 21 nulliparous women served as an additional control group. At the first visit none of the Siagraphs examined for the case or control groups aroused suspicion of dysplastic naevus or melanoma and no significant structural changes were noted during the observation period. However, 2.1% of the melanocytic naevi in the pregnant group increased and 1.3% decreased in size. Corresponding figures in the non-pregnant group were 1.8% and 0%, respectively. Only one naevus in a pregnant woman increased slightly in epidermal pigmentation, and a decrease in pigmentation was noted in 3.7% of the melanocytic naevi in the cases and 1.8% in the controls. None of the differences within or between the groups was statistically significant. We conclude that pregnancy does not influence the appearance of pigmented naevi. A changing naevus during pregnancy should be examined carefully and considered for excision and histopathology.
Serum Antioxidant Capacity in Polymorphic Light Eruption
Authors: Guarrera Marcella , Rebora Alfredo
Published: April 2023

Polymorphic light eruption is one of the few dermatological diseases in which some antioxidants have been said to be reduced in both the epidermis and the blood. This study measured the hydrosoluble antioxidant capacity in the serum of patients with polymorphic light eruption, using a commercially available kit. All patients were tested in winter, in order to avoid the influence of exposure to ultraviolet light. The results showed that a hydrosoluble antioxidant capacity was significantly decreased (by 29%) in patients with polymorphic light eruption, and b) that females (both patients and controls) has less hydrosoluble antioxidant capacity (by 27%) than males. In addition, the hydrosoluble antioxidant capacity values for females with polymorphic light eruption increased significantly with age, possibly accounting for the well-known propensity of young women to polymorphic light eruption. These last observations have not been reported previously.

Low-dose Oral Methotrexate Induces Apoptosis of Tissue Eosinophils in Bullous Pemphigoid
Authors: Dahlman-Ghozlan Kristina , Ortonne Jean-Paul , Bahadoran Philippe , Spadafora Anne , Stephansson Eija
Published: April 2023

We have shown previously that eosinophils are abundant in blood and tissue in bullous pemphigoid and that they rapidly disappear, without sign of necrosis, during methotrexate therapy. The aim of the present study was to investigate the role of apoptosis in this phenomenon. The terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labelling method for detecting apoptosis was used, combined with immunohistochemical detection of eosinophils before and during oral methotrexate. The numbers of apoptotic eosinophils were compared using light microscopy. Eosinophil apoptosis was significantly higher in skin after one week of methotrexate therapy and the number of eosinophils was reduced. The results indicate that methotrexate therapy induces apoptosis of the tissue eosinophils in bullous pemphigoid.

Skin Pigmentation Kinetics After UVB Exposure
Authors: Ravnbak Mette H. , Philipsen Peter A. , Wiegell Stine R. , Wulf Hans C.
Published: April 2023

There have been few previous studies of the kinetics of pigmentation following ultraviolet B (UVB) exposure, and these have included only fair-skinned persons. The current study investigated pigmentation increase to steady state and fading in 12 Scandinavians and 12 Indians/Pakistanis. Over a period of 3 weeks the subjects were UV-irradiated 6 times on the right side of the back and 12 times on the left side using a Solar Simulator and narrowband UVB with equal sub-Minimal Melanogenesis Doses (individually predetermined). Pigmentation was measured from skin remittance at 555 nm and 660 nm (allowing correction for erythema). The absolute pigmentation increase was independent of pre-exposure pigmentation, therefore the percentage pigmentation increase was higher in fair-skinned volunteers. The UV dose to minimal pigmentation was higher in darker-skinned persons for single and multiple UV exposures for both UV sources. Going from a single exposure to 6 and 12 exposures, the required dose to minimal pigmentation was reduced by factors of 2 and 3, respectively, for both UV sources, thus reducing the risk of sunburn, but the cumulative dose increased 3- and 4-fold, respectively. This result was independent of skin type and pre-exposure pigmentation. Fading took 4-5 months and was not related to frequency of UV exposure or to ethnic origin.

Published: April 2023

Data regarding narrowband ultraviolet B (NB-UVB) phototherapy in patients with chronic urticaria is limited. The aim of this open, controlled study was to determine whether NB-UVB is effective in treating urticaria in combination with antihistamin. A total of 81 patients with chronic urticaria were recruited, 48 of whom were randomized into the NB-UVB plus antihistamine group. The control group (n = 33) received only antihistamine. Patients were assessed using the urticaria activity score and a visual analogue score (VAS). The 2 groups were evaluated at the same time-points: at treatment sessions 10 and 20 and at follow-up 3 months post-treatment. The reduction in urticaria activity score and VAS was statistically significant (p < 0.05 for both groups). When comparing the groups, the mean urticaria activity score was significantly lower in the NB-UVB group at session 10 (22.6 vs. 27.3) and session 20 (17.4 vs. 20.7). Statistically significant differences were also noted in VAS between the 2 groups (p < 0.01) at 3 months post-treatment. We conclude that NB-UVB may be an effective complementary treatment for patients with chronic urticaria.

Atrichia with Papular Lesions: A Report of Three Novel Human Hairless Gene Mutations and a Revision of Diagnostic Criteria
Authors: Yip Leona , Horev Liran , Sinclair Rodney , Zlotogorski Abraham
Published: April 2023

Atrichia with papular lesions is a rare autosomal recessive condition characterized by complete irreversible hair loss during the first months of life and papules that appear during early childhood. Atrichia with papular lesions is frequently misdiagnosed as alopecia universalis, despite increasing reports of its prevalence and the presence of well-defined diagnostic criteria. Most cases of atrichia with papular lesions have been reported in consanguineous families residing in small geographical regions, but the increasing number of sporadic cases of unrelated individuals suggests that atrichia with papular lesions is more common than previously thought. Mutations in the human hairless gene on chromosome 8p12 have been implicated in this disease. Here, we report two novel heterozygous mutations in an Australian family and a novel homozygous mutation in 2 Arab siblings. We also revise the diagnostic criteria for atrichia with papular lesions in order to clarify its uniqueness and distinguishing features from alopecia universalis.

Measurement of Liver Iron Content by Magnetic Resonance Imaging in 20 Patients with Overt Porphyria Cutanea Tarda before Phlebotomy Therapy: A Prospective Study
Authors: Dereure Olivier , Jumez Nicolas , Bessis Didier , Gallix Benoit , Guillot Bernard
Published: April 2023

Liver iron content was evaluated by a magnetic resonance imaging-based method in 20 consecutive patients with either sporadic or familial porphyria cutanea tarda. Serum ferritin, hepatitis C infection and the presence of the 2 main mutations of the hemochromatosis gene were also investigated. All patients showed good clinical response to phlebotomy. Initial liver iron content was normal (< 40 micromol/g) in 9 cases, slightly increased (40-59 micromol/g) in 3 cases, moderately increased (60-99 micromol/g) in 6 cases or markedly increased (100-199 micromol/g) in 2 cases). The ferritin level was raised (> 400 ng/ml) in 14/20 patients and there was no obvious relationship with liver iron. Increased liver iron content was observed more frequently in patients with hemochromatosis mutation and less frequent in those with hepatitis C infection. Clinical response to phlebotomies was slightly better in patients with increased liver iron content even slightly, but patients with normal liver iron content also responded well, which suggests that iron depletion is an outstanding treatment independent of liver iron content. This study shows that increased liver iron content is not a constant finding in patients with porphyria cutanea tarda, especially in women, and that it is not a prerequisite for the efficiency of phlebotomy.
Psoriasis and Dyslipidaemia: A Population-based Study

Published: April 2023

Previous reports demonstrated an association between psoriasis and the metabolic syndrome. The aim of this study was to elucidate the association between psoriasis and dyslipidaemia. A cross-sectional study was performed utilizing a population-based database. Psoriasis patients were compared with enrollees without psoriasis regarding the prevalence of dyslipidaemia and lipid levels. Comparison of lipid levels was performed on a "low-risk" subset of subjects without diabetes, hypertension and cardiovascular disease. The study included 10,669 psoriasis patients and 22,996 subjects without psoriasis. The prevalence of dyslipidaemia was significantly higher in psoriasis patients (odds ratio (OR) = 1.48, 95% confidence interval (CI) 1.40-1.55). The association remained significant after controlling for confounders (OR = 1.19, 95% CI 1.12-1.26, p < 0.001). In multivariate analysis of the "low-risk" subset, triglyceride levels were higher in psoriasis patients and high-density lipoprotein cholesterol levels were lower. This study supports previous reports of an association between psoriasis and lipid abnormalities.

Prevalence and Clinical Characteristics of Chronic Urticaria and Positive Skin Prick Testing to Mites
Authors: Kulthanan Kanokvalai , Wachirakaphan Charussri
Published: April 2023

The aim of this study was to review chronic idiopathic urticaria patients with positive skin prick testing to mites and the clinical relevance of this positivity. Case records of patients with chronic idiopathic urticaria who underwent skin prick testing during the years 2000 to 2007 were reviewed. The studied allergens included house dust mite allergens; Dermatophagoides pteronyssinus and farninae. A total of 172 patients were enrolled in the study. The prevalence of positive skin prick testing to mites among patients with chronic idiopathic urticaria was high (34.9%), but had little clinical relevance (3.3%) to their urticarial symptoms. Patients with mite-sensitization were more commonly male and more often had a personal or family history of atopy compared with those without mite-sensitization.

Prevalence of Atopic Dermatitis in Italian Schoolchildren: Factors Affecting its Variation
Authors: Naldi Luigi , Parazzini Fabio , Gallus Silvano
Published: April 2023

The frequency of atopic dermatitis in Italian children and its relationship with selected variables were analysed in a large survey of skin health conducted in Italy. In 1997 we conducted a survey on schoolchildren aged 12–17 years from 13 areas of northern, central and southern Italy. For the present analyses, 3179 Caucasian children (1618 males, 1561 females) were considered. A diagnosis of atopic dermatitis was reported in 224 cases (7.0%). The frequency of reported atopic dermatitis was significantly higher in children with asthma (rate ratio (RR) 4.5; 95% confidence interval (CI) 3.1–6.5). The lifetime prevalence of a diagnosis of atopic dermatitis was higher among schoolchildren reporting a diagnosis of psoriasis (RR 5.5, 95% CI 3.0–10.1) and vitiligo (RR 16.1, 95% CI 6.5–39.5). This study gives estimates of the lifetime prevalence of atopic dermatitis in adolescents in Italy and emphasizes the direct association between the condition and other immune-related skin diseases.

Adoption of appropriate scanning strategy on selective laser melting of stainless steel 316L to enable healthy mesenchymal stem cells response
Authors: Xie Weijie , Hussain Issam , Man Hau-Chung , Chan Chi-Wai
Published: April 2023

In this study, an appropriate scanning strategy in selective laser melting [SLM, also known as laser powder bed fusion (LPBF)] was adopted to enhance the forming quality of stainless steel (SS) 316L for load-bearing implant applications, with a particular focus given to investigate the effect of argon flow velocity inside the build chamber. The biocompatibility of the resulting printed surfaces was evaluated by in vitro culturing of mesenchymal stem cells (MSCs) at different time points up to 96 h. Notably, it is one of the first studies to document the MSC response on SLM 316L surfaces. The results showed that highly dense parts (>99.8% density) can be produced by carefully selecting the interlayer rotation, scan vector length, and hatch distance. Microsized surface defects (i.e., balling) appeared after the SLM process. Their chance of occurrence and size were found to be related to the gas flow velocity inside the build chamber. The resulting printed surfaces were hospitable for MSCs, and healthy cell response was recorded throughout the 96-h culture periods. These findings can be instrumental in optimizing the surface features of SLM in order to improve the cell response.
Servicios ecosistémicos del suelo en la producción de leche en Chitagá, Norte de Santander, Colombia
Authors: Tovar-Quiroz Ana Delfina
Published: April 2023

Los suelos son parte importante en la producción de los sistemas agropecuarios. Sus características físicas, químicas y biológicas prestan servicios ecosistémicos para el funcionamiento del ciclo del agua y los nutrientes que no son reconocidos como beneficios en sistemas productivos como el lácteo. Esta investigación permitió el reconocimiento de los servicios ecosistémicos del suelo entre los productores de leche del municipio de Chitagá, Norte de Santander, los cuales son proveedores de la materia prima para los productores de queso tipo Chitagá, que tiene proyección a la denominación de origen. A 58 productores de leche se les aplicó una encuesta relacionada con la valoración de servicios ecosistémicos y se realizó un análisis de fertilidad a 10 muestras de suelo con vocación lechera. Los productores de leche están ubicados en sectores de alta montaña, con clima frío y un área destinada a pasto kikuyo en asocio con leguminosas. La materia orgánica para la mayoría de los suelos es baja, con capacidad de intercambio catiónico baja, sin limitaciones para potasio, pero sí para magnesio; el fósforo es alto para la mayoría de los suelos, pero está poco disponible por el pH ácido. La fertilidad del suelo, el suministro de agua dulce, la regulación de la temperatura y la precipitación fueron reconocidos por los productores como las contribuciones directas más importantes en la producción de leche. La evaluación de los servicios de ecosistemas y el uso de las metodologías permite la toma de decisiones asociadas a la gestión sostenible de recursos naturales aplicada a cadenas productivas.

State-level Taylor rule and monetary policy stress
Authors: Duran Hasan Engin , Gajewski Pawel
Published: April 2023

Research background: Taylor rule is a widely adopted approach to follow monetary policy and investigate various mechanisms related to or triggered by monetary policy. To date, no in-depth examination of scale, determinants and spillovers of state-level monetary policy stress, stemming from the Federal Reserve Board?s (Fed?s) policy has been performed.
Purpose of the article: This paper aims to investigate the nature of monetary policy stress on US States delivered by the single monetary policy by using a quarterly dataset spanning the years between 1989 and 2017.
Methods: We apply a wide array of time series and panel regressions, such as unit root tests, co-integration tests, co-integrating FMOLS and DOLS regressions, and Spatial Panel SAR and SEM models.
Findings & value added: When average stress imposed on states is calculated, it is observed that the level of stress is moderate, but the distribution across states is asymmetric. The cross-state determinants behind the average stress show that states with a higher percentage of working-age and highly educated population, as well as those with higher population density and more  export-oriented are negatively stressed (i.e. they experience excessively low interest rates), whereas higher unemployment rate contributes to a positive stress (too high interest rates). To the best of our knowledge, the contribution of this paper lies in estimating monetary policy stress at the state level and unveiling some of the determinants of this stress. Moreover, the paper makes the first attempt to empirically test spatial spillovers of the stress, which are indeed found significant and negative.
Factors influencing the choice of the invoicing currency in international trade: Panel data analysis for 55 countries
Authors: Twarowska-Mól Katarzyna
Published: April 2023

Research background: Most transactions in world trade are invoiced in several international currencies. The changes in the distribution of the great economic powers and the strengthening of the position of developing countries make it necessary to consider the factors determining the choice of trade invoicing currency and to assess the prospects of the dollar as an invoicing currency and the possibility of strengthening the position of developing countries' currencies in this function.
Purpose of the article: The aim of the paper is to assess the factors influencing the choice of invoicing currency for international trade in 2000?2019.
Methods: The analysis of factors influencing the choice of international trade invoicing currency is based on panel data modelling. The study is conducted for a group of 55 countries. It is assumed that the following variables may influence the currency position in the trade invoicing function: the share of the issuer's country in the bilateral trade, inflation and exchange rate.
Findings & value added: The analysis showed that despite the decreasing share of the United States in world trade, the U.S. dollar remains the most important export invoicing currency. The main factors influencing the dollar's dominance are the U.S. share of countries' exports, inflation in developing countries, and the exchange rate in advanced economies. The great significance of trade share as a determinant of the position of the trade invoicing currency is an important indication of the strengthening position of developing country currencies, particularly the Chinese yuan. The obtained results confirm, with the use of more complete data, the validity of the dominant currency paradigm and enrich the still underdeveloped analysis in the area of international macroeconomics using panel data analysis.

Published: April 2023

Research background: Immigrant entrepreneurship remains a key issue for researchers, politicians, and policymakers. It has been widely discussed from different angles among various researchers in recent studies ? particularly in Europe. However, there is a lack of studies to present the motivation of the causal relationship between immigrant entrepreneurs.
Purpose of the article: This study aims to fill the gap and analyze the causal relationship between the motivations of Asian immigrant entrepreneurs in Germany.
Methods: The study was conducted through a face-to-face interview using a predesigned questionnaire from Asian business owners in Germany and the Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach was applied to analyze the data.
Findings & value added: The results show that capital acquisition, employment, financial problems in the family, and existence opportunities in the market are the factors that have higher priority, and may highly impact the Asian immigrant entrepreneurial decision. On the other hand, relatives or social networks remain the lowest priority factor that encourages Asian immigrants towards self-employment. The study has also found that entrepreneurship in the family, the state support policy for immigrants, low level of education, unfamiliarity with the local language, and dissatisfaction with the previous job belong to the cause group. However, some of the motivating factors relate to the effect group, such as capital acquisition, opportunity in the market, immigrant community ties or social networks, unemployment, and financial problems in the family. The most affected factor among the effect group is unemployment, while immigrant community ties or social network is the least affected factor. This study includes a novel interpretation of the DEMATEL approach that researchers have not yet addressed; therefore, it is highly relevant for policymakers, especially those interested in migration studies. Finding out the main driving forces behind Asian immigrant entrepreneurs in a developed European nation like Germany and how these drivers affect cause-and-effect interactions between them are the contributions that add value to the field.

It is well known that urban parks, especially wooden ones, cause a cooling effect on the urban climate and have a decisive role in the formation of the so-called Park Cool Island (PCI). Urban parks can help at lowering the land surface temperature (LST), and consequently mitigate the effects of the surface urban heat island (SUHI). The thermal characteristics of the Urban Park Cancicov from Bacău city are analyzed using LANDSAT-8 imagery, but also in-situ measurements for the growing season of 2022 (March to October). For the calculation of LST based on LANDSAT images, several methods have been applied among which the monowindow method has been finally used. The results showed that Cancicov Park, through its structural characteristics and its central position in a densely-built area, determines a cooling effect in an area where the SUHI intensity reaches the highest values. During the day the LST is by 4.50C lower compared to densely built areas in the surroundings for April-September, the diurnal LST exceeding 300C from May to August, while the surrounding urban LST exceeds 350C from June to August. Regarding the results from in-situ measurements, we have used the monitoring results from 2 points, one represented by the monitoring point located in the city center (“Gheorghe Vrănceanu” College) and the second one located on the eastern side of the park (“Ștefan cel Mare” College). The diurnal thermal differences between these two points rise to over 2.50C during the summer morning hours. At the nocturnal level, thermal differences are reduced from 0.75 to 10C. This study emphasizes the capacity of green areas to alleviate the UHI, providing viable information for urban planners to correctly assess climate risks and guide development management by maximizing the intensity of PCI.

Managing recurrent otitis externa in dogs: what have we learned and what can we do better?
Authors: Nuttall Tim
Published: April 2023

Recurrent otitis externa is a common problem in dogs. Topical treatment for each flare is successful in the short term, but repeated cycles of inflammation and infection lead to chronic inflammatory changes, pain and aversion, and antimicrobial resistance. These make the flares more frequent and harder to control. Eventually, the changes become irreversible and require a total ear canal ablation/lateral bulla osteotomy or ablative laser surgery. Most ear canal surgery is avoidable if recurrent otitis is properly managed at an earlier stage. This requires a different mindset and approach to these cases, taking advantage of recent research and clinical findings. Most importantly, clinicians must appreciate that all recurrent ear infections in dogs are secondary. To achieve a good long-term outcome, it is essential that all the underlying factors in each case are diagnosed and managed using the primary, secondary, predisposing, and perpetuating framework. This means that the primary condition must be diagnosed and managed, the secondary infection treated, predisposing risks identified and corrected, and the perpetuating factors reversed. Treatment is in 2 phases: induction to get the ears in remission and then long-term maintenance therapy to prevent relapses. Treatment should be appropriate to each dog but will typically involve ear cleaning, topical antimicrobial therapy, and topical or systemic glucocorticoids. Novel treatments for infection and inflammation will offer additional options in the future. Understanding the triggers for recurrent otitis in dogs will help clinicians plan effective management regimens that will make a huge difference to the quality of life of their patients and their owners.
Trade Facilitation During COVID-19 Pandemic
Authors: Petrović Ivana Popović
Published: April 2023

The role of international trade was irreplaceable at the start of the COVID-19 pandemic crisis, especially the trade in medical supplies and food for all affected countries. Trade as a part of this crisis, certainly should not be an element of further countries` closing and new trade barriers implementation. On the contrary, it could be a way to exceed these problems, especially if all participants in the trade point out the same aims of the normal trading during the pandemic crisis and implementation of Trade Facilitation Agreement provisions. The effects of Trade Policy measures during the COVID-19 crisis and their relation with the Trade Facilitation Agreement were analyzed in this paper. Trade measures applied at the beginning of the crisis have dual character, trade facilitating and trade restricting. This paper highlights the tariff reduction and non-tariff barriers decrease, as possible approaches for the trade policy. The aim of this paper is to show the extent to which the TF agreement, ratified recently, could be applied during the time of the pandemic. This paper provides an overview of a number of trade policy measures that have slowed down the implementation of this agreement. It also points out the role of this agreement, as one of the most important instruments that could be used to expedite the movement of goods, which is especially necessary during the pandemic.

This is primarily a result of the fact that the reorientation of business activities to this type of storage and integration of data and applications represents a major change in the business world, and the growth trend continues in all aspects of the business. This paper deals with the possibilities and challenges of applying cloud technology in oil companies operating in turbulent conditions caused by fluctuations in oil prices in the global market..
The Effects of Globalization on the International Competitiveness of the Western Balkan Countries
Authors: Savićević Marko , Veselinović Petar , Makojević Nikola
Published: April 2023

The Western Balkan countries, which are in the late transition process, fail to take advantage of the opportunities brought by globalization and the removal of restrictions to the free flow of capital, technology, knowledge, people and information. Despite the entry of a significant stock of foreign capital into these countries, they failed to significantly improve the technological level of production and the competitiveness of their economies. The subject of the paper research is the examination of the impact of globalization on the reached level of competitiveness of the economies of the Western Balkan, as well as the countries of Central and Eastern Europe, in the period before the emergence of the COVID crisis. The question raised in the paper is to what extent the process of globalization and the entry of transnational corporations into the Western Balkan countries affected their economies’competitiveness. These two issues permeate each other to a large extent, considering that the governments of the transition countries believe that the foreign capital inflow, in the form of highly sophisticated technology, will simultaneously enable the completion of the transition process and a more decisive integration of the five countries of the Western Balkan in global investment and trade flows. The research confirmed that the degree of involvement in international economic flows has a statistically significant and positive impact on the growth of competitiveness, and that these effects are more pronounced in the Western Balkans than in the Central and Eastern European regions.

Authors: Jakšić Milena , Todorović Violeta , Matić Jelena
Published: April 2023

Historically, financial and monetary innovations have triggered positive and negative changes in the everyday operations of the financial sector. Similarly, digital currencies can significantly reshape the future of banking and financial intermediaries. Whether the aspect of digital currencies is through the public sector such as in central banks, digital currencies, or private means such as in cryptocurrencies, the eventual rollout of such innovative instruments has a critical influence on the retail use of digital assets. At the same time, digital currencies may create new risks and vulnerabilities in the financial or banking sector whose implications should be thoroughly assessed. However, the magnitude of the risks depends on the designs and policies attached to the digital currencies in use. These features of digital currencies trigger the subject of discussion in this paper. By outlining the benefits and risks associated with digital currencies in the banking sector, the paper aims to highlight the overall impact of digital currencies in the banking sector and available remedies to control the risks. Therefore, the paper provides information that is critical to the banking sector policymakers interested in digital currencies.

After drastically changing the global tourism and hospitality industry, the current pandemic made hotel companies better understand the new situation and begin to adapt to new market developments. The hotel industry has made significant advances and changes in its business to guarantee the health and safety of guests. This research aimed to examine the consequence of hotels' protective measures against the COVID-19 virus on guest attitudes about protective measures, satisfaction and behavioural intentions. Research findings indicate the protective measures versus COVID-19 utilized by hotels in Serbia positively impact guest attitude towards the measures and guest satisfaction. In contrast, the impact on behavioural intentions is not statistically significant. Additionally, guest attitude towards the measures positively affects guest satisfaction. Guest satisfaction positively affects guest behavioural intentions, while the relationship between guest attitudes and behavioural intentions is not statistically significant.
