Production and export of ornamental fish is a lucrative market opportunity. It has earned valuable foreign exchanges during the past years. This study was conducted to identify the factors that have led to the systematic growth of ornamental fish export in North Western Province, Sri Lanka. North Western Province was selected for this study due to its favorable climate and suitable space for ornamental fish farming. Primary data was collected from all thirteen exporters engaged in the export of ornamental fish in the Kurunegala and Puttalam Districts of the North-Western Province by using a self-administered questionnaire. The collected data were analyzed through Statistical Package for Social Sciences (SPSS) version 29. KMO and Bartlett’s Test, Reliability Test, and Descriptive Statistics were used to analyze the data. Four hypotheses were developed to measure the relationship between the variables and examined using Pearson Correlation Analysis and Multiple Regression Analysis. The results of this study revealed that the factors of ornamental aquaculture technology, knowledge and skill development, production cost, and awareness of the market were positively correlated to the systematic growth of ornamental fish exports. Subsequently, ornamental aquaculture technology, knowledge, and skill development were found to significantly affect the systematic growth of ornamental fish exports, while production cost and awareness of the market were found to be insignificant. Overall, this study found that the independent variables of ornamental aquaculture technology, knowledge, and skill development affect the systematic growth of ornamental fish exports in the North Western Province of Sri Lanka. This study recommended that by identifying the factors behind the growth in the export of ornamental fish, strategies, incentives, and programs should be put in place for its improvement.

Import of agri-food products to Ukraine
Authors: Dukhnytskyi Bohdan , Pugachov Volodymyr
Published: January 2025

Ukraine's foreign trade in agri-food products continues to develop despite the full-scale war. While the blocking of seaports at the beginning of the Russian invasion had an equally negative impact on exports and imports of Ukrainian food, it is now possible to speak of the stabilization of agricultural purchases abroad. The purpose of the article is to examine the current state of imports of agri-food products to Ukraine, including the most significant changes in its commodity and geographical structure that have occurred since 2022. The methods used were theoretical generalization, historical and logical, analysis and synthesis, comparative evaluation, statistical, expert evaluation, graphical and tabular. The dynamics of agricultural imports to Ukraine in 2013-2023 is presented, with the periods of recessions and growth highlighted. The article determines the share of food products in total imports, examines the situation with the balance of foreign trade by subgroups, analyses the geographical and commodity structure of foreign purchases with details on fruits and berries, fish and seafood, and beverages, pays special attention to imports from the European Union, classifies certain commodity items based on their impact on the domestic food market, and assesses future trends in agri-food imports to Ukraine based on primary data for 2024. The provisions of the article are aimed at identifying the specific features of imports of agricultural raw materials and foodstuffs to Ukraine and informing specialized Ukrainian companies and relevant public authorities about possible prospects for the development of foreign procurement based on the monitoring of relevant data

The study aimed to identify key threats to the Ukrainian agricultural sector in the context of the war and to develop proposals for overcoming them through effective governance, government support and infrastructure investment. The study was conducted based on an analysis of socio-economic indicators of different regions of Ukraine with a focus on the agricultural sector. The data collection covered the period from 2022 to 2023 and included indicators of unemployment, investment activity, agricultural sector productivity, and the effectiveness of government support programmes. A comparative analysis was conducted between the regions affected by the hostilities and more stable regions, and the impact of infrastructure investment on economic stability was also investigated. The study determined that the Ukrainian agricultural sector has been severely affected by the hostilities, leading to increased unemployment, reduced investment and widening economic gaps between regions. The highest losses were observed in regions bordering the conflict zone, such as Kharkiv and Dnipro regions. In these regions, investment activity has completely stopped, which has significantly reduced the productivity of the agricultural sector. At the same time, regions with more developed infrastructure performed better due to access to markets and financing. The study also demonstrated that state support had an uneven impact on different regions, with the most affected regions receiving insufficient support. The study results highlighted the importance of infrastructure investment and comprehensive state support to overcome regional disparities in Ukraine’s agricultural sector and stabilise the economic situation in the face of the ongoing conflict

The study aimed to assess the impact of investments in agricultural technology on the productivity, economic efficiency and profitability of farming enterprises. The emphasis was on analysing yields of the three leading agricultural holdings in Ukraine: Svarog West Group, Stepova and Agroproduct LLC, which operate in different natural and climatic conditions. The methodology involved collecting data for three agricultural seasons (2021-2023), which was used to identify long-term trends and determine the impact of technology investments on key performance indicators of enterprises. A correlation analysis with the calculation of Pearson's coefficients was used to assess the relationship between agricultural technology expenditures and yields. The economic efficiency was calculated based on profitability and resource efficiency, which compared the results between agricultural holdings and identified management features in different conditions. The main results showed that investments in agricultural technology have a positive impact on yields, although their effectiveness depends on the specialisation of the farms and environmental conditions. For Svarog West Group, a strong correlation between investment and yield was determined (r = 0.85), which highlights the importance of technological innovation. Agroproduct LLC demonstrated the highest level of profitability (40%), which indicates effective cost management. In turn, Stepova achieved the highest efficiency of resource use (0.0056 t/thousand UAH) due to its specialisation in seed production. The results showed that it is necessary to combine technological innovation with adaptation to climate conditions to ensure the long-term efficiency of agricultural production. These findings can be useful for researchers, managers and practitioners involved in agricultural sector development and seeking ways to achieve food security in a changing climate
Vitamin D, Calcium to Magnesium, and the Gut Microbiome
Authors: Chambers Patrick
Published: January 2025

The gut microbiome has been the subject of increasing interest as integral to our health. Few realize that the enormous benefits of vitamin D (VD) and magnesium (Mg) are highly dependent on a healthy gut microbiome. Short chain fatty acids, especially butyrate, reflect not only a healthy gut microbiome but also VD status. Suboptimal VD, Mg, or butyrate translates to some degree of gut dysbiosis and vice versa. Mg dependent secondary bile acids, indoles, and tryptophan, all microbial metabolites and longevity agents, are also discussed. Mg is indispensable to not only the synthesis of the active form of VD but also that of 7-dehydrocholesterol (7-DHC) from acetate. 7-DHC is the substrate for solar conversion to D3. The steadily increasing Ca:Mg in the Western diet and its ironic impact on parathormone (PTH) is discussed. Gut dysbiosis further complicates this. Biochemical and physiologic interlinkages are legion and most remain hidden. This limited mini review exposes insight into the tight linkage between 25(OH) D and Ca:Mg, facilitated by the gut microbiome. A model incorporating the physiologically discordant but reinforcing effects on this linkage based on genes, culture, socioeconomic status, and diet that also addresses the seemingly contradictory reports regarding calcium (Ca), Mg, and VD efficacy is proposed.

ДЕЯКІ АСПЕКТИ ІНОЗЕМНОГО ДОСВІДУ ПІДГОТОВКИ ФАХІВЦІВ МИСТЕЦЬКОЇ ОСВІТНЬОЇ ГАЛУЗІ
Authors: Тарчинська Юлія Георгіївна , Івченко Галина Андріївна , Сітовський Леонід Петрович
Published: January 2025

Актуальний закордонний досвід підготовки фахівців мистецької освітньої галузі свідчить про належну оцінку спільнотою економічно розвинених країн мистецтва як важливого чинника збереження історичних, національних та культурних цінностей, як стратегічного засобу соціального, економічного, освітнього розвитку суспільства, дієвого способу формування творчого потенціалу особистості, її здатності до духовного та інтелектуального зростання. Ефективність освітньої системи цих країн спонукає до вивчення інноваційних практик в іноземній мистецькій освіті, прийнятних для використання у вітчизняному навчально-виховному процесі. Урахування гуманістичного підходу згідно зарубіжного досвіду передбачає: створення максимально сприятливих умов для професійного становлення та самовдосконалення особистості, унікального розвитку кожного здобувача шляхом надання можливостей для реалізації його власної освітньої траєкторії, розкриття засобами мистецької освіти у її міждисциплінарних зв’язках особистісного духовного та художнього потенціалу й формування ціннісної системи на національному ґрунті, культури толерантних взаємин. Компетентнісно орієнтована підготовка майбутніх фахівців мистецької освітньої галузі передбачає залучення студентів до інтенсивного навчання із поступовим включенням їх у різні види практичної діяльності. Це підносить цінність творчо-діяльнісного підходу, основними завданнями якого в контексті дослідження виявлено: орієнтування освітнього процесу на суспільно значущі результати, ефективне поєднання індивідуального самостійного навчання з інноваційною колективною (а також автономною) креативною діяльністю, продуктивна партнерська взаємодія студентів із викладачами- наставниками, шкільними педагогами, менторами. Зорієнтованість освітньої політики провідних іноземних держав на регіональні суспільні інтереси та інтеграційні процеси актуалізує гуманітарний підхід, що забезпечує сприятливі умови для підготовки фахівців у системі мистецької освіти: адаптивність і гнучкість, варіативність змісту високоякісної освіти, у тому числі наявність великого вибору освітнього ресурсу на рівні закладів, широко- та вузькопрофільних спеціальностей, програм підготовки, інтеграція уявлень з різних галузей знань. З погляду перетворення освітнього середовища на засіб якісної діагностики, моделювання та прогнозування результатів підготовки майбутніх фахівців до їх професійної самореалізації важливим є іноземний досвід щодо: міжособистісної взаємодії на принципах академічної доброчесності, забезпечення комфортного середовища в умовах інклюзивного навчання, актуального матеріально-технічного супроводу освітньої діяльності.
СТАНОВЛЕННЯ ПРОФЕСІЙНОГО БАНДУРНОГО МИСТЕЦТВА ДРУГОЇ ПОЛОВИНИ ХХ СТОЛІТТЯ
Authors: Турко Наталія Євгеніївна , Горбатюк Ірина В’ячеславівна
Published: January 2025

У статті детально досліджуються фундаментальні процеси, які сформували професійне бандурне мистецтво в другій половині ХХ століття. Цей період характеризується стрімким переходом від аматорського музикування до високого рівня концертного виконавства. Автор акцентує увагу на важливості історичного періоду "відлиги", який створив сприятливі передумови для розвитку української культури загалом і бандурного мистецтва зокрема. Лібералізація суспільства, зростання інтересу до національної спадщини та відродження національної самосвідомості стали вагомим стимулом для розвитку бандурного мистецтва. Особливу увагу приділено суттєвій модернізації конструкції бандури, завдяки зусиллям таких майстрів, як Олександр Корнієвський та Василь Герасименко, що дозволило виконавцям досягти небувалого рівня майстерності. Поява хроматизованих бандур, із розширеним діапазоном та покращеними акустичними властивостями, відкрила нові можливості для виконавської техніки. Викладено поетапність відкриттів спеціалізованих класів бандури у провідних музичних навчальних закладах, таких як Київська та Львівська консерваторії, що стало важливим кроком у становленні професійної бандурної освіти. Видатні педагоги, зокрема, Володимир Кабачок, Сергій Баштан та Василь Герасименко, сформували національну виконавську школу. Дослідження має вагоме значення для розуміння історії української музичної культури та розвитку національного інструменту – бандури.

Los estudios con insectos acuáticos en Puerto Rico se iniciaron a principios del siglo pasado. La mayoría de los taxa han sido bien documentados; sin embargo, carecemos de información sobre otros taxa y no existe un documento único que contiene toda la información dispersa. Estos son los principales obstáculos que enfrenta el estudio de insectos acuáticos en la isla. En este trabajo realizamos una recopilación de datos recolectados en artículos publicados, tesis de grado, cursos universitarios, estudios de impacto ambiental y una revisión del material depositado en Museo de Zoología de la Universidad de Puerto Rico. El objetivo fue compilar la primera lista de familias de insectos acuáticos de Puerto Rico. En total se registraron 61 familias de siete órdenes de insectos. Los órdenes mejor estudiados han sido Ephemeroptera, Trichoptera y Odonata. El orden más diverso es Diptera, seguido de Coleoptera y Hemiptera. En términos generales, Puerto Rico es una isla diversa comparada con otras islas de las Antillas Mayores, no obstante su tamaño. Este estudio es un primer intento por integrar el conocimiento de los insectos acuáticos en una lista y de esta manera contribuir a mejorar el conocimiento de los insectos acuáticos. Adicionalmente, esperamos que la información ayude a los responsables en la toma de decisiones relacionadas a la conservación, y también incentive los estudios ecológicos y biogeográficos en los ecosistemas acuáticos de Puerto Rico.

Se evaluaron reportes de géneros de coleópteros acuáticos de la familia Elmidae encontrados en el estado adulto en aguas corrientes de Colombia, analizando la literatura taxonómica usada para la identificación, y a través de un análisis de plausibilidad zoogeográfica. Se comprobaron como erróneos aproximadamente el 42% de los géneros reportados, y el 15% de los reportes en total, atribuyendo 12 géneros neárticos y un género del Viejo Mundo a la fauna colombiana de élmidos. Se estima que la proporción total de reportes equivocados pueda ser significativamente mayor, básicamente generada por la aplicación de claves taxonómicas no adecuadas para la identificación taxonómica de la fauna neotropical. Por otro lado, una clave existente, apropiada para los géneros suramericanos (Manzo 2005), se encontró como claramente subaprovechada. Se presentan algunas notas complementarias a la misma clave, junto con recomendaciones generales para la identificación taxonómica de élmidos neotropicales y un listado actualizado de los géneros americanos, con datos sobre sus principales áreas de distribución

Human Resources Management in Museums
Authors: Šveb Dragija Marta
Published: January 2025

This PRISMA systematic review aims to investigate the human resources management (HRM) challenges faced by museums and potential strategic solutions. Despite being a valuable asset, HRM in museums has presented significant challenges for museum management, which until now have not been systematically researched. The analysis was conducted throughout July 2023, with the final sample including 32 records. The findings reveal eight key HRM challenges: digital revolution, co-creation of exhibitions, outdated leadership approaches, lack of crisis and climate change management, high staff turnover, challenges in creating an inclusive museum environment, lack of staff competencies, and organizing staff training. To navigate these challenges successfully, museums can implement a range of strategic solutions. These solutions center on skills development, the adoption of contemporary leadership approaches grounded in collaboration, and the crucial role of organizational and legislative support for staff and talent development in museums. Although the study is limited in the number of records covered, due to the dearth of studies on HRM in museums, it marks the first systematic examination of the HRM challenges in museums, enriching the field of museum and heritage studies by shedding light on the current obstacles impeding the creation of positive, talent-nurturing work environments within museums.

Proboscideans were keystone Cenozoic megaherbivores and present a highly relevant case study to frame the timing and magnitude of recent megafauna extinctions against long-term macroevolutionary patterns. By surveying the entire proboscidean fossil history using model-based approaches, we show that the dramatic Miocene explosion of proboscidean functional diversity was triggered by their biogeographical expansion beyond Africa. Ecomorphological innovations drove niche differentiation; communities that accommodated several disparate proboscidean species in sympatry became commonplace. The first burst of extinctions took place in the late Miocene (approximately 7 million years ago (Ma)). Importantly, this and subsequent extinction trends showed high ecomorphological selectivity and went hand in hand with palaeoclimate dynamics. The global extirpation of proboscideans began escalating from 3 Ma with further extinctions in Eurasia and then a dramatic increase in African extinctions at 2.4 Ma. Overhunting by humans may have served as a final double jeopardy in the late Pleistocene after climate-triggered extinction trends that began long before hominins evolved suitable hunting capabilities.

Published: January 2025

The Indonesian online gaming industry is growing rapidly. The increasing number of online game players among teenagers can cause various health impacts, one of them being carpal tunnel syndrome. This research aims to determine the relationship between online gaming habits with carpal tunnel syndrome in high school students in Jakarta. This research is an observational study with a cross-sectional design and a total of 62 samples. Questionnaires used in data collection include  playing habits, respondent knowledge, and the Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ). The collected data was analyzed using the Chi-Square test. The results showed  a relationship between playing duration (p=0.042), playing frequency (p=0.026), and repetitive movements (p=0.026) with complaints of Carpal Tunnel Syndrome. On the other hand, there was no significant relationship between gender (p=0.523), game type (p=1.00), gaming device (p=0.287), and knowledge (p=0.744) with complaints of Carpal Tunnel Syndrome. It would be better if the school provided further education to students and parents about the dangers of prolonged game duration and reminded them to regulate game-playing hours for students to avoid complaints of Carpal Tunnel Syndrome.

Published: January 2025

This research proposes a vision-guided autonomous navigation framework for unmanned vehicles performing image acquisition for bridge inspection. The proposed framework integrates visual SLAM with RGB-D image input with semantic segmentation to detect and localize critical structural components like columns. The detected components are converted to the parametric map to generate navigation goals for image collection. The proposed approach is first validated in the synthetic bridge inspection environment using an unmanned ground vehicle. The feasibility of the framework is further studied by the laboratory-scale prototyping and validation using TurtleBot3 equipped with Jetson TX2 onboard computer. In the simulation environment, the proposed framework can achieve autonomous navigation to up to 6 columns and acquisition of image data with 90% success rate for 3 columns. Furthermore, the performance evaluation in the real-world environment shows that the developed hardware-software prototype can navigate and collect image data of up to 2 columns, with more than 60% success rate navigating to the first column. The results indicate the significant potential of achieving autonomous navigation and image acquisition with limited onboard computational resources, contributing to the enhanced efficiency and reliability of bridge management.

Authors:   Clinic for Ear, Nose and Throat Medicine, Bundeswehr Central Hospital, Germany, Sandra Schmidt
Published: January 2025

Introduction: Intratympanic Cortisone Injections (ITI) have been established for sudden deafness for years. ITI can be used as primary
therapy and, above all, as rescue therapy if systemic administration has not brought any improvement or if there are contraindications
to systemic administration.
Methods: Many different forms of application, indication, duration and treatment have been used. Different local anesthetics, cortisone
preparations, body and head positions are practiced.
Results: 103 patients are analyzed. In 55 cases, the injection after oral therapy. In 48 cases, given immediately due to extreme hearing
loss or comorbidities the injections are well tolerated with rare unpleasant side effects.
Discussion: High-dose treatment with cortisone has been used for decades. The HODOKORT study brought significant dose
reductions. The KORTEBO study could not be carried out, but there is need for it. There is a lack of evidence of an optimal indication,
implementation and objective proof, which is urgently needed.
Conclusion: The results of the study listed here in relation to existing studies show that ITI is beneficial as a supportive therapy after
insufficient hearing improvement with systemic cortisone administration.

Preservation of the diversity of wild honey bees is complicated by insufficient knowledge about their distribution and status in individual territories. The wild population of the western honey bee A. Mellifera, which exists in the territory of Polissia of Ukraine, is an aboriginal subspecies and a natural component of the fauna of these places. The purpose of the research is to assess the current state of this population, which has been preserved thanks to the development of the ancient craft of local residents for extracting honey – «bortnitsvo». Such beekeeping is based on the capture of wild swarms and does not involve selective breeding. Wild honey bees are a valuable genetic resource for biodiversity conservation, as they are an important reservoir of local adaptations that determine their survival in the wild. The results of the physical and chemical analysis of honey obtained from the apiaries of local beekeepers of the Polissia Nature Reserve: diastase – 29.73DN, pH – 4.9, F/G – 1.41, HMF – 6.33mg/kg, proline – 608.87mg/kg, and melissopalynological analysis of pollen in honey, % (Callúna vulgáris – 35, Potentilla erecta – 19, Frangula alnus – 10, Lamium purpureum – 8, Vaccinium myrtillus L – 5, Sisymbrium officinale L – 5, Quercus robur L – 4, etc.) confirmed its botanical origin and value as a source of nutrients for bees. The assessment of the frequency of pollen grains showed the absence of pollen of one species in more than 45%. Only two species are defined as secondary. This is the pollen of the Callúna vulgáris L family (Ericaceae) – 35 % and Potentilla erecta L (Rosaceae) – 19 %. Pollen of such species as Frangula alnus L (Rhamnaceae), Lamium purpureum L (Lamiaceae), Vaccinium myrtillus L (Ericaceae), Sisymbrium officinale L (Brassicaceae), Quercus robur L (Fagaceae), Artemisia vulgáris L (Asteraceae), although they occupy the studied honey together 35 % of the total volume of pollen, however, according to the classification, each of these species is defined as important secondary. Pollen of Potentilla erecta L, Frangula alnus L, Lamium purpureum L, as species with the longest flowering season, remain available almost throughout the honey collection season, and the anemophilic pollen-producing tree of the Fagaceae family Quercus robur L is a common source of pollen for honey bees in Polissia forests.
Key words: aboriginal subspecies, beekeeping, pollen, fresh honey, wild honey bees.
Irritant effect and efficiency of inclusion of spirulina biomass enriched with sulphur in the young dogs’ diets
Authors: Hryhorash Yu. , Merzlov S.
Published: January 2025

The content of nutrients and biologically active substances in the biomass of Spirulina platensis allows it to be used effectively in animal diets. By adjusting the mineral composition of the nutrient medium for Spirulina platensis, it is possible to change the content of macronutrients in the cells of the blue-green algae. One of these mineral elements is sulphur. This element is an essential component of several amino acids, enzymes, vitamins and coenzymes. By introducing additional doses of Sulphur (purified, nutritional form and glauber’s salt) into the nutrient medium, Spirulina platensis biomass with a high content of the element under study was obtained. To further use spirulina biomass with a high content of Sulphur as a feed additive in the feeding of farm animals and poultry, it is advisable to study the harmful effects of blue-green algae biomass and to establish the effectiveness of its inclusion into animal diets. The study aimed to determine the irritating effect of Spirulina platensis biomass with a high sulphur content on the mucous membranes of the eyes and to establish the effectiveness of its inclusion in the diet of young dogs. The irritant effect has been studied by applying a suspension of Spirulina to the conjunctival sac of the left eye of rabbits aged 2.5 months and weighing 2.32-2.33 kg. The experimental animals have been observed for 14 days. At the end of the study, the serum of rabbits was examined for protein metabolism. To study the effectiveness of using spirulina biomass as a feed additive, puppies from the control group were fed a feed mixture without adding algae. Dogs from the I-III experimental groups were fed a feed mixture containing Spirulina platensis biomass with a high content of sulphur in the amount of 0.5, 1.0 and 1.5 % by weight. The study of the irritating effect of spirulina biomass proved its non-toxicity, which allows it to be used as a feed additive, including in the feeding of young dogs. No disturbances in protein metabolism in rabbits were found when a suspension of Spirulina platensis biomass was applied to the mucous membrane of their eyes. The addition of 1.0 and 1.5 % of Spirulina biomass to the feed mixture increased the body weight of puppies by a statistically significant amount.
Keywords: experimental animals, the harmful effect of Spirulina platensis biomass, puppies’ body weight, feed mixture, hyperaemia, oedema.
The impact of war on consumer behavior of food market buyers in Ukraine

Published: January 2025

The impact of war on changes in consumer behavior of buyers in the food segment was investigated. The methodological basis of the study is the scientific publications of Ukrainian and foreign scientists on the factors influencing consumer behavior during crises. The methods used are description, formalization, generalization – to determine the state of food security in Ukraine during the war; analysis and synthesis – to determine the key factors of consumer behavior of food market buyers during crisis phenomena; observation and induction – to present the food preferences of Ukrainians and their purchasing power in different regions during the war; analysis of dynamics and structural shifts – to study changes in the main characteristics of consumer behavior during the full-scale invasion of russia in Ukraine; tabular and graphical ‒ to visualize the results. The key factors that affect consumer decisions in times of crisis are economic instability, safety and psychological aspects. It is found that during the war these determinants acquire a new meaning. The state of Ukraine's food supply changed during the war, but the consumer activity of Ukrainians did not undergo significant changes, as the Ukrainian agricultural sector demonstrated high resilience and adaptability to wartime risks. The logisics system of food distribution to regional markets of Ukraine has withstood the critical load and proved to be both socially and economically efficient. As for the quality of the diet, there is a risk of further deterioration due to a significant increase in food prices and a decrease in their economic availability. The purchasing behavior of Ukrainians in the food segment in wartime has changed significantly compared to the pre-war years. There have been changes in demand for products by category, a tendency to prefer long-term storage products, and a significant proportion of the population restricting their food expenditures. The largest restrictions are in the southern and central regions; the smallest are in Kyiv and western Ukraine. Online food purchases have increased, and the war has attracted those who had not done so before to online shopping. The deterioration in consumer security has led to a change in consumer priorities and a redistribution of spending. Established gastronomic practices of Ukrainians have been disrupted, and daily eating patterns and diets have changed. There is a «panic shopping» phenomenon – the accumulation of food stocks that gives people a sense of control over the high-risk situation that has arisen as a result of the disaster. Consumer commitment to domestic brands, in particular those that support the Armed Forces and socially vulnerable categories of Ukrainians, has increased significantly.
Key words: war, consumer behavior, food, purchasing power, panic shopping, brands.
Effect of organic amendments on morphological, physiological and root characteristics of red amaranth (Amaranthus gangeticus) grown on Cd contaminated saline soils
Authors: Hossain Mohammad Zaber , Islam Md Atikul , Islam Md Azharul , Kibria Khandoker Qudrata
Published: January 2025

A pot experiment was conducted to investigate the effects of six different types of organic amendments (OAs) applied to Cd contaminated saline soils with varying rates on red amaranth (Amaranthus gangeticus) growth. Two levels of salinity (4 dSm-1 and 8 dSm-1) were developed in the experimental soil that was previously contaminated with 5 mg kg-1 Cd. In slightly (4 dSm-1) saline soil, 1% vermicompost (VC) produced 18.77 times higher fresh weight as compared to the control while 32.37 times higher found with 2% cowdung (CD). VC produced the maximum fresh weight in moderately saline soil (8dSm-1). Other morphological traits were improved with the addition of OAs. VC increased the plant's relative water content, chlorophyll-a and chlorophyll-b. Root characteristics were improved irrespective of the OA rates and salinity. The efficiency of OAs followed the order VC=CD>compost>WT>SD=RH. Therefore, OA could be a promising way of alleviating the saline soil contaminated with Cd.

Published: January 2025

Optimized composite flour from wheat flour (WF) and orange fleshed sweet potato (OFSP) meal was used for the production of chin-chin. The roots of OFSP were washed, air-dried, peeled, sliced to 1 cm thick, dried at 50 oC for 18 h and then milled to pass 200 µm sieve aperture to obtain OFSP flour. Composite flours (CF) were formulated from OFSP and WF using Simplex Lattice Design (SLD) and its characteristics were analyzed and modelled. The indices for validating the models showed adequacy of the models. The CF had improved water absorption capacity, oil absorption capacity and beta-carotene. Meanwhile, optimization of relevant properties resulted in an optimized CF which comprised 12.5% OFSP flour and 87.5% WF. The sensorial scores of chin-chin from the optimized CF indicated acceptability by the taste panelists.  Chin-chin from the optimized CF would contribute to beta-carotene intake of consumers while reducing wheat importation.
