Labor productivity is a key indicator of economic development and public well-being. This study assesses the structural shifts, regional dynamics, and sectoral trends in the domain of labor productivity in the Russian Arctic from 2011 to 2021, identifying aggregated economic sectors. The findings reveal that labor productivity levels in the Russian Arctic exceed the national average, primarily due to the resource-based nature of regional economies. However, a major issue is the persistently high level of interregional differentiation in labor productivity within the Arctic. The study demonstrates that an initially high level of labor productivity does not necessarily ensure long-term growth. An analysis of structural shifts in labor productivity over the past decade indicates a shift towards the market sector of the Arctic economy, evidenced by an increased share in gross regional product (GRP) and a decrease in time worked. Within the market sector, several trends are observed: the leading role of the extractive industry is maintained due to its expanding share in GRP; the role of agriculture is growing, reflected in a decreased share of hours worked; and the importance of other market sector branches, particularly transport, communication, and electric power, is diminishing as their share of total hours worked increases. The observed decline in labor productivity within the non-market sector suggests the potential for negative social consequences for the Arctic population. An analysis of labor productivity growth rates indicates that the leading sectors in terms of growth are mining, finance and business services, construction, and trade. These sectors can be considered sources of economic growth in the Arctic. Interregional differences in labor productivity growth rates within the same sector of the Arctic economy suggest the influence of regional factors, highlighting the potential for discovering unique reserves of productivity growth in each region.

This paper explores the environmental and economic resilience of the regions within the Arctic zone of the Russian Federation (AZRF). We define a region's environmental and economic resilience as its capacity to withstand external shocks, independently restore the balance between its economy and environment, and transform while maintaining or improving the balance between its environmental and economic systems. The study's relevance stems from the rapid industrialization of the Russian Arctic in recent years and the constraints on investment in environmental technologies, green production, and management. The study discusses an analysis of macroeconomic, environmental, and economic indicators of the Russian Arctic regions, examining their interrelations during the pandemic crisis and under the pressure of Western sanctions. From 2018 to 2022, the anthropogenic impact on the environment in the Russian Arctic gradually declined, although the situation varied for individual indicators depending on trends in the regional sectors. Regions were identified that lead in environmental and economic resilience as well as those showing increased anthropogenic impact despite declining industrial production. A multidimensional classification of regions in the Russian Arctic was developed based on indicators characterizing the state of the environmental and economic spheres. Clusters of regions with high, low, and limited levels of environmental and economic resilience were identified. The study revealed that the macroeconomic situation in these regions is more dynamic than their environmental and economic conditions. Macroeconomic indicators in the Arctic regions demonstrate different trends during periods of external shocks. Overall, the Russian Arctic economy was sensitive to the 2020 crisis; the 2022 sanctions had a negative impact on economies focused on Western markets, and in 2023, macroeconomic dynamics slowed down across all regions of the Russian Arctic. Further research is necessary to understand the factors influencing the environmental and economic resilience of the Russian Arctic regions under current conditions.

The intensification of economic activities by oil and gas companies in the Arctic has significantly increased the risk of environmental damage, necessitating compensation for potential harm caused by these businesses. A major risk factor in this context is accidental oil spills, which are particularly challenging to predict, thereby complicating the assessment of their consequences and the development of preventive measures. The most advanced forecasting methods rely on probabilistic assessments of spill risk factors, which require special field studies and statistical data. This research considers the key approaches to the economic assessment of environmental damage, emphasizing the need to consider the unique characteristics of the Arctic.The goal of the study is to estimate the most probable soil damage from accidental oil spills using a simulation model. It will be especially relevant for territories where the area affected by accidental oil spills is considerable or has increased significantly over the past few years, according to available statistical data. In the Arctic, the Usinsky District of the Komi Republic is one such region. Using the case of this district, an assessment of potential damage is conducted for three scenarios with varying levels of pollution. The results enable an evaluation of potential damage, providing different values corresponding to multiple scenarios with distinct probabilities. The findings can inform oil and gas companies in developing preventive measures and assist regulatory authorities in determining appropriate environmental reparations from companies.

The implementation of national projects for establishing a unified national transport network determines the relevance of studying the spatial organization of transport infrastructure, including the assessment of transport development across individual regions. One such region is the Arctic zone of the Russian Federation, a macro-region with unique characteristics. This study aims to identify interregional differences in the development of land transport infrastructure in Russia’s Arctic regions and assess the adequacy of transport provisions in meeting current and potential cargo transportation demands during the pre-pandemic period. The authors conducted a retrospective analysis of changes in the length of paved public roads and the operational railway network in the Arctic regions, focusing on the period from 2000 to 2020. Key indicators of transport security, such as the Engel, Uspensky, and Vasilevsky coefficients, were used for nonlinear evaluation. The scientific novelty of this research lies in uncovering key trends and patterns in land transport infrastructure development and assessing the level of transport security in the Russian Arctic during the pre-pandemic era. The study’s findings confirm persistent territorial imbalances in land transport infrastructure development and interregional disparities in the pace and scale of new road and railway construction. The main insights and conclusions of this article can inform public authorities when preparing territorial strategies and transport infrastructure development programs for the Arctic regions, as well as in the training of state and municipal officials. The authors’ future research will focus on exploring trends and specificities of land transport development under current geopolitical conditions, aiming to evaluate the effectiveness of public policy in developing a backbone transport network in the Arctic during times of crisis.

Published: October 2024

In the building sector, the majority of efforts are aimed at achieving greater energy efficiency, a low carbon footprint, and optimum thermal comfort to make buildings more efficient, more sustainable, and more pleasant to live in. In this context, this paper aims to assess the impact of integrating environmentally friendly and green materials (lime-hemp plaster and hemp concrete) into the envelope of an existing residential building. A numerical simulation study was carried out using TRNSYS 18, in four Moroccan climates: Mediterranean, cold semi-arid, hot semi-arid, and hot and dry desert, to study the energy, economic, and environmental impact, as well as that of the thermal comfort. The proposed construction scenarios are compared with the reference scenario in terms of heating and cooling requirements, electricity bills, carbon footprint, and percentage of annual thermal discomfort. The results show that energy savings are highest in the cold semi-arid climate (Oujda) at around 24%. Hemp concrete construction is more effective in reducing heating requirements, with a reduction of up to 39.4%. For cooling, the reduction is only 15.5%. The economic and environmental study shows that using materials such as hemp concrete in an optimal construction and climatic context can reduce electricity bills by 25% and CO2 emissions by around 23.7%. However, the reduction in terms of hours of discomfort is not yet significant enough. Hence the need to combine this technique with other strategies based on bioclimatic design. The use of hemp plaster and concrete for renovating existing buildings or constructing new ones represents a very promising alternative from several points of view: energy, economic, and environmental.

The principal focus of this exploration is to study the computationally simulate the combined convection of CMC-water-based Casson hybrid nanofluid through a stretching sheet with electric magnetic force in a porous medium. Copper (Cu) and Silver (Ag) nanoparticles are included to enhance the heat transfer performance of CMC-water. The physical problem is formulated with mathematical PDEs, and to solve this, initially we used similarity transformation technique to reduce the PDEs into ODEs, then Runge-Kutta Fehlberg method (RKFM) of order four with shooting technique is adopted for further reduction from the non-linear ODEs to first order DEs. The influence of key parameters such as the magnetic field parameter (M), porous medium parameters (K), electric field factor (E), radiation parameter (Nr), permeability parameter (λ), Casson parameter (β), and Eckert number (Ec) on relevant physical quantities is illustrated through tables and graphical visualizations. The impact of these parameters on velocity and temperature profiles, as well as on the skin friction coefficient and Nusselt number of the nanofluid, is observed. Our results indicate that an increase in the Casson parameter values leads to a decrease in the velocity of the host fluid in the case of opposite flow, and a similar behavior is observed with the nanoparticle porous medium parameter (K) in the case of assisting flow. Furthermore, the use of the Runge-Kutta Fehlberg Method (RKFM) is found to be more accurate and reliable in dealing with the problem studied in this work.

Published: October 2024

In various hazardous locations, gas mask filters are essential to protect from airborne pollutants and harmful gases. However, under certain conditions, such as the weather or climate in some locations can affect gas mask filtration. Based on a previous study, the existing geometry of the gas mask filter cartridge unit been analyse for its preferential flow within the gas mask domain, which resulted in a significant pressure drop and heat concentration in the filter, affecting the filtration. However, another study suggested designing the main sieve passageway of the filter to help in resolving the pressure drop and create much well distribution of flow within the cartridge. In this study, three geometries with re-design of the main sieve passageway of the filter were made and simulated to determine the preferential flow using the computational fluid dynamics (CFD) method. Two filter concentrations (300 ppm, and 1000 ppm) and constant humidity ratios of at 80 % were simulated. The presence of the dead zone was examined using the computational fluid dynamics (CFD) method, which was controlled by the Navier-Stokes equation and continuity based on several flow parameters. Based on the result occupied can be concluded, the second geometry had a much better velocity contour distribution around 40% than the other geometry, maintaining the overall minimum velocity area even though the formation of the dead zone area for the second geometry was 10% higher at the lower part of the filter than for the third geometry. The abilities of the second geometry to perform well even in the presence of higher concentrations brought to the honeycomb-based design as the main sieve passageway actually improve the velocity distribution and then minimizing formation of “dead zone”. Concluding justified that the proposed geometry met the prediction of improving the pressure drop and create quite well distribution of flow in the filter. prediction of improving the pressure drop and create quite much well distribution of flow in the filter.

Published: October 2024

This research investigates the effects of heat transfer on the stagnation-point flow of a non-Newtonian Casson fluid in a two-dimensional magnetohydrodynamic (MHD) boundary layer over a stretched sheet, considering thermal radiation impacts. By employing similarity transformations, the governing partial differential equations are transformed into nonlinear ordinary differential equations. The obtained self-similar equations are numerically solved using the Optimal Homotopy Analysis Method (OHAM). The numerical results are graphically represented, showcasing the influence of various parameters on fluid flow and heat transfer characteristics. The study uncovers important dynamics in transport phenomena. Examining and illustrating the effects of dimensionless parameters on velocity, temperature, and concentration profiles reveal significant insights. Moreover, skin friction and Nusselt number results for Casson fluids are analyzed and presented. The findings indicate that the Casson parameter and Hartman number act in opposition to fluid momentum, while the thermal conductivity parameter enhances fluid temperature. Thus, this research provides valuable insights into MHD boundary layer flows of non-Newtonian Casson fluids with thermal radiation effects, and the OHAM solution method proves effective in predicting flow transport properties.

Published: October 2024

Energy storage serves the dual purpose of narrowing the disparity between energy provision and consumption while also enhancing the efficiency and dependability of energy generation systems, thereby assuming a crucial position in energy storage. This technology reduces expenses by gathering and using wasted energy. Thermal energy storage using phase transition materials is a highly regarded technology in thermal energy storage. Studying energy storage tanks that incorporate phase transition material is a novel area of research in the energy world. Sodium nitrate is the PCM material employed in this study. This discussion focuses on the influence of the alumina percentage and tank dimensions on the behavior of molten sodium nitrate over time. This analysis incorporates the influence of the diameter-to-length ratio based on the Grashof number. Consequently, ten different dimensional states of the tank are taken into account. This study discusses the findings from analyzing energy storage tanks incorporating phase change material using Ansys Fluent software. To achieve this objective, the initial step involves presenting the ratio between the required dimensions and the Gershoff numbers acquired for various diameters. Subsequently, the mesh convergence process and the solution's independence from the grid are explained. Subsequently, he showstate d the outlines of the aqueous portion and the temperature derived from the study, culminating in presenting the findings. The temperature distribution inside the tank becomes increasingly homogeneous by augmenting the proportion of alumina included in sodium nitrate. The addition of alumina particles to sodium nitrate has a diminishing impact as the height-to-diameter ratio of the tank is reduced. As the tank transitions from state 1 to state 7, whose diameter and height are identical, the curvature of the temperature change graphs diminishes. This drop signifies a reduction in the rate at which the phase-change material melts.

Authors:   National Association of Korean Local Government Studies, Kim Dong-Uk , Park Seong-Min , Seo Jung-Wook
Published: October 2024

This study empirically analyzed the determinants of job burnout among firefighters using decision tree analysis. Furthermore, to consider the various detailed factors of job burnout, the study examined not only overall job burnout but also its subdivisions, including reduced sense of accomplishment, emotional exhaustion, and loss of self-identity. The decision tree analysis revealed that organizational system factors and organizational fairness factors were the characteristics of the group with the highest level of job burnout. Among organizational system factors, groups with a strong perception of task avoidance showed higher levels of reduced sense of accomplishment, emotional exhaustion, and overall job burnout. Additionally, groups experiencing conflicting instructions from higher authorities or supervisors exhibited higher levels of emotional exhaustion and overall job burnout. Regarding fairness factors, groups that perceived their compensation as inadequate relative to their duties and performance demonstrated higher levels of loss of self-identity and overall job burnout. Based on these findings, the policy implications of this study are as follows: First, there is a need to enhance programs aimed at alleviating job stress for firefighters. Second, an appropriate compensation system should be established based on job performance.

Authors: SARIGÜL Nedim
Published: October 2024

Since the first years of the Republic, various policies have been developed to enable citizens to contribute to the economic, social, and cultural life of the country. Education was seen as the most important means for the success of these policies and projects were designed to educate the villagers, who constitute most of the population. Policies developed for village education during the single-party period continued during the Democratic Party period. However, the new government produced new projects in line with its own policies and made radical changes in the institutions and organizations within the old policy. This change was felt especially in primary education, religious education, and village institutes. In the first years of the Democratic Party's rule, various media outlets emerged thanks to the freedom it provided to the press. One of these publications is The Journal of Eğitim Hareketleri, which started its publication life in 1955 by Hıfzırrahman Raşit Öymen. The Journal has tried to produce solution suggestions by addressing the problems that the Turkish education system has encountered since the first years of the Republican Era. The journal includes articles by foreign and local educators, as well as literary experts, theologians, historians, and sociologists who are experts in their fields. It is seen that The Journal of Eğitim Hareketleri also attaches importance to villages and education in villages. The Journal includes the policies implemented during the Single Party and Democrat Party periods regarding the enlightenment of the villagers and the education of the village children. In this context, the problems of village schools and village teachers and the place of village children and villagers in the Turkish education system are discussed. In this study, it was tried to reveal how the issue of education in the village was managed in The Journal of Eğitim Hareketleri during the Democratic Party period

Authors: Hašková Simona , Šuleř Petr , Divoká Lenka
Published: October 2024

Purpose – The research identifies the impact of the Russia-Ukraine war on the stock prices of six publicly traded European airlines and evaluates their ability to adapt to this situation.
Research methodology – The dependence of the development of airline stock prices on the level of public and institutional stress due to the war was measured using GoogleTrends and is analysed on the basis of a Vector Autoregression model (VAR).
Findings – A short-term negative relationship was confirmed between the development of stock prices and GoogleTrends; the impact of the stress related to the war was negligible about 5 months after the outbreak thereof. Those companies that were the fastest to adapt to the shock of the war in terms of share prices are identified.
Research limitations – The link between GoogleTrends, as an input variable reflecting market sentiment, and the stock prices of European airlines, is considered a limitation.
Practical implications – The impact of investor sentiment on the returns on the stocks of airlines is a thing of the past; which is an important finding for financial market participants and airlines alike.
Originality/value – The ability of the specific airlines to adapt to the shock of war creates a competitive advantage.

Published: October 2024

Extreme climate events such as floods and droughts are becoming increasingly frequent and intense across the world. Future climate scenarios predict both an increase in individual extreme events, as well as chronic changes in climatic seasonality. Yet, the combined and relative effects of these pressures on ecosystems remain unknown. Concurrently, human-induced ecological disruption is accelerating species extinction rates, which are estimated to be 100 to 1000 times greater than pre-human levels. This is alarming as greater biological diversity is thought to buffer ecosystem functioning against extreme climate events, thereby safeguarding the provisioning of essential ecological services that contribute to human well-being. However, how and to what extent biodiversity buffers ecosystems against climate variability remains unclear. We recently constructed experimental grassland communities in a mesocosm-based field design representing a realistic gradient of plant diversity. Both extreme events (drought and flood) and a change in seasonality of precipitation are manipulated in a full factorial design to quantify the effects of future seasonal shifts and extremes in precipitation. We will: 1) determine to what extent higher biological diversity ensures that grasslands can continue to provide multiple ecosystem services even in the context of climate change and 2) unravel the fundamental mechanisms by which this is achieved including species asynchrony and positive species interactions. Results of our experimental approach will advance our understanding of the buffering potential of plant diversity and contribute to the development of strategies for sustainable service provisioning of our ecosystems in the face of climate change.
Nurses’ Generational Differences of Burnout and Turnover Risk
Authors: Rutledge Dana , Douville Sarah , Winokur Elizabeth
Published: October 2024

This study aimed to determine the impact of nurse generation on (a) turnover risk factors (low meaning/joy in work, low resilience, high occupational fatigue, high burnout) and (b) turnover intentions before and during the COVID-19 pandemic. Survey methods were used to compare two samples of hospital nurses who completed online surveys in 2017 or 2021. The results were compared on burnout and turnover risk by generation. Results indicate that in 2017, high acute fatigue and low inter-shift recovery differed by nurse generation, with Baby Boomers (Boomers) being the least affected. Additionally, Boomers were the least likely to report a likelihood of leaving the hospital within 6-12 months. However, in 2021, Millennial nurses experienced significantly higher levels of low meaning and joy in work, low resilience, high acute fatigue, low inter-shift recovery, and high burnout than Generation X (GenX) and Boomers. Millennials were the most likely generation to report turnover intention. This leads to the conclusion that the pandemic may have worsened the work experience of millennial nurses and increased their risk of leaving hospital jobs and the profession.
Embracing a Multigenerational Workforce: A School Nursing Perspective
Authors: McCabe Ellen , Cogan Robin , Jameson Beth
Published: October 2024

There are four generations of nurses in the current workforce. This article reviews the opportunities and challenges of multigenerational nursing practice through the lens of school nursing. Each generation of school nurses brings its unique characteristics to the specialty practice. The success of generational diversity in nursing can be attributed to embracing each group’s nuances, needs, and contributions. There are possibilities for mutual mentorship between the generations, as each group brings their talents, skills, and passion to their practices. It will be foundational in nursing, regardless of specialty, to embrace the idea of the multi or intergenerational nursing workforce. The future of a robust nursing profession requires acceptance, integration, and welcoming of all voices and stages of practice, as well as innovative ideas.
Unit-Based Ethics Rounds: Creating an Ethical Work Culture for Nurses in the Hospital
Authors: Morgan Jennifer , Jones Joanne , Milliken Aimee
Published: October 2024

Nurses who work in a hospital setting with seriously ill patients often face ethical dilemmas with no clear solutions but instead difficult choices and uncertainty. Unit-based ethics rounds in the hospital can be tailored to unit specific needs. However, there is a gap in the literature describing how to implement such unit-based rounds. This article describes the experience of nurses who implemented unit-based ethics rounds on one unit using the Integrated Ethics Model as a framework and the feasibility of continuing ethics education into the practice setting. Eight sessions described targeted two of the three Integrated Model’s focus areas: systems and processes, and environment and culture. Seven of the sessions targeted all three foci, and also included decisions and actions. The design of this project maximized exposure to education about ethics in nursing, reflected the unit pace and culture, and has normalized and engaged nurses in ethical thinking and actions. The Integrated Ethics Model provides a feasible framework that can focus unit-based ethics rounds and expand nursing ethics education into practice at the unit level.

Analyses revealed that moisture, protein, fat, ash, crude fiber, and carbohydrate content of pumpkin powder were 8.5%, 5.2%, 1.2%, 3.4%, 4% and 77.7% respectively. Biscuits were made by replacing wheat flour with pumpkin powder at different levels as 0, 5, 10, 20, 30, and 40% (w/w) in the standard formulation. When the percentage of pumpkin powder increased from 10 to 40%, the thickness of biscuits decreased significantly compared to control (0%) There was a significant increment in the spread ratio of biscuits between 10 and 40% levels of pumpkin powder when compared with the control. While 10 to 40% replacement levels of pumpkin powder resulted in significant increase in biscuit hardness, it decreased moisture content significantly compared to control. The color of the biscuits was assessed in terms of lightness, redness, and yellowness. When increasing the pumpkin powder percentage in biscuit, lightness reduced, while redness and yellowness increased gradually. Consumer acceptability test on sensory attributes indicated 5% (w/w) level of pumpkin powder was the most preferred replacement level. The study concludes that pumpkin powder has the potential to be used in biscuit applications.

Quantifying the nutrient mineralization in soils amended with different materials is vital for understanding the nutrient availability for plant uptake. It helps to improve nutrient management by minimizing nutrient loss from the soil. The present research was conducted as a laboratory incubation to assess the nitrogen (N) and carbon (C) mineralization in Ultisols amended with cattle manure, spent poultry layer litter, Gliricidia leaves (Gliricidia sepium), leaf litter compost, urea, and Siam weed leaves (Chromolaena odorata). A Completely Randomized Design (CRD) was used with four replicates, and means were compared with Duncan’s multiple range test (DMRT) after analyzing the data with the SPSS 25 statistical package. CO2-C evolution in amended soils increased up to day 14 of incubation and became stable as incubation progressed. The highest total flux of CO2-C (171.89 g/kg) was obtained in cattle manure-amended soil. Compost-amended soil showed significantly higher (p=0.05) release of mineralized nitrogen (1530.31 mg/kg) over unamended control. The pH in all the amended soils increased over time, with the highest pH in soil amended with compost. Thus, the present study indicated rapid C and N mineralization when different amendments are integrated into the soil.

Plectranthus zeylanicus is an indigenous, multi-functional herb used in traditional medicine. Due to over-exploitation from the natural habitats, the species is on the verge of extinction. Therefore, commercial cultivation of the species is needed to satisfy the rising demand while protecting its genetic base. The current study was designed with three trials to identify the most suitable cutting type, potting media, and irrigation schedule for P. zeylanicus. Four distinct cutting types (tip cutting, triple nodal cutting, double nodal cutting and single nodal cutting), five different potting mixtures (topsoil: sand: compost-1:1:1, topsoil: sand: compost-1:2:1, topsoil: sand: compost-1:1:2, topsoil: compost -1:1, topsoil: compost-1:2) and four different irrigation schedules (daily watering to field capacity level, daily watering to half of the field capacity level, every other day to the field capacity level, every other day to half of the field capacity level) were used in Completely Randomized Design with ten replicates. Survival percentage (%), number of leaves, the height of the plant (cm), average length of roots (cm), average leaf area (mm2), and chlorophyll content (SPAD Unit) were measured as growth parameters. Data were analyzed using SAS software with a 5% significance levels. Highest survival percentage (95%), highest average root length (26.8 cm), average leaf area (80.5 mm2) and a higher chlorophyll content (31.1 SPAD Unit) were recorded from tip cuttings of P. zeylanicus. Furthermore, the topsoil: sand: compost-1:1:1 combination showed a higher survival percentage (90%), number of leaves (3), highest average plant height (43.9cm) and average root length (20.2 cm) with significantly (P<0.05) higher average leaf area (52.3 mm2) and chlorophyll content (31.07 SPAD Unit). Daily watering to the field capacity showed a higher survival percentage (90%), significantly higher (P<0.05) number of leaves (3.7), plant height (51.6 cm), higher root length (25.5 cm), the highest average leaf area (80.0 mm2) and chlorophyll content (32.7 SPAD Unit). Therefore, tip-cutting planted in topsoil: sand: compost-1:1:1 media can be recommended for successful propagation of P. zeylanicus.

Jackfruit (Artocarpus heterophyllus L.) is a popular seasonally grown crop in Sri Lanka. The by-products generated from jackfruit season are mostly used as animal feed or landfilled without being used. Therefore, this research aimed to characterize the nutritional and functional properties of jackfruit by-product flour (jackfruit core and rags; 3:1 w/w) while exploring its potential use to develop pasta. The physico-functional properties, proximate composition, and antioxidant properties of jackfruit by-product flour compared with commercial wheat flour were analyzed. Composite flour was prepared by substituting wheat flour with different amounts of jackfruit by-product flour (25%, 35%, and 40% w/w). Thirty semi-trained panelists were used to conduct a sensory evaluation to select the best pasta made from a composite flour mixture. Proximate composition, physical properties, and shelf-life of the selected best product were analyzed using standard methods; in comparison to wheat flour, jackfruit by-product flour displayed a higher water absorption capacity (8.77±0.06%) and swelling capacity (46.00±5.66 mL), indicating that it can be used for making bakery products with enhanced properties. The jackfruit by-product flour contained a significantly (p<0.05) high amount of crude fiber (13.00±1.13%) compared to the wheat flour (2.24±0.23%). Further, the total phenolic and flavonoid content of jackfruit by-product flour were 40.9±0.02 mg GAE (Gallic acid equivalent)/100 g and 65.7±0.02 mg QE (Quercetin equivalent)/100 g, respectively, and it showed 8.46 ± 0.01 mg TE (Trolox equivalent)/100 g DPPH radical scavenging activity. The pasta made from 25% (w/w) jackfruit by-product flour showed the highest mean rank values for all the tested sensory attributes. The shelf-life study showed that the developed product could be stored in low-density polyethylene laminated packages for 6 weeks under ambient temperature. In conclusion, jackfruit by-product flour can be used as a partial replacement for wheat flour when preparing pasta.

Mycosis Fungoides (MF) is the most common cutaneous T-cell lymphoma that typically presents in the early phase as inflammatory erythematous patches or plaques, with epidermotropism as the histopathological hallmark of the disease. Traditionally, in the early stages, non-aggressive options represent the first-line strategy: topical corticosteroids, phototherapy, radiotherapy and occasionally adopting a 'wait-and-see' approach for minimally symptomatic patients. In patients with advanced or recurrence disease, good results can be achieved with immune modifiers, chemotherapeutic agents, total skin irradiation or extracorporeal photochemotherapy and maintenance therapy is often required. The past decade has seen an expansion of therapies that can be used in this setting by increasing new therapeutic strategies. Herein are resumed the key advancements coming from recently published trials.
