Consumer awareness and adoption of multi-source edible oils: key influencing factors and barriers
Authors: Asmithaa G , Chandrakumar M , Murugananthi D , Vanitha G , Parameswari E
Published: January 2025

Edible oils are essential to Indian cooking methods and flavour profiles and they have long been a component of human nutrition and culinary traditions. These oils, derived from a range of plant sources, significantly improve the taste, texture and nutritional value of food. In recent years, there has been a surge in interest in Multi-Source Edible Oils (MSEO), also known as blended oils, which combine two or more types of vegetable oils to create products with improved cooking properties and nutritional profiles. Edible oil consumption is influenced by various factors, such as marketing efforts, culinary preferences and health consciousness. As lifestyle-related health conditions such as cardiovascular disease and diabetes become more prevalent, many consumers are becoming more concerned about their cooking oil choices. The purpose of this study is to examine consumer awareness, adoption factors and barriers related to MSEO in Coimbatore, Tamil Nadu. The study uses statistical tools like factor analysis and Garrett ranking to identify the major factors and constraints in adopting MSEO. The study reveals that, while most respondents are aware of MSEO, only a few use it. Product performance emerges as the main factor influencing adoption, while marketing, health and economic variables also play a role. Major barriers include higher prices, preference for traditional oils and lack of knowledge. These findings can aid the development of strategies to enhance MSEO adoption, potentially leading to healthier dietary practices in the region.

Published: January 2025

This review aims to comprehensively analyze the variability of climate in agriculture and theadaptive behaviour of farmers in response to climate change, synthesizing existing knowledge andexamining measures for mitigate climate fluctuations. To achieve this, a systematic literaturereview (SLR) was conducted using the Scopus database, covering the past eleven years. A total of177 articles were identified through a methodological application of the Preferred Reporting Itemsfor Systematic Reviews and Meta-analyses (PRISMA) framework. While these studies encompass abroad geographical scope, the selection was deliberately constrained by a small sample size toexclude regions lacking conflicting evidence, ensuring relevance and high-quality information, astandard practice in systematic reviews within this field. This study hypothesizes that adaptivestrategies, such as climate-smart agriculture and early warning systems, significantly reducefarmers’ vulnerability under climate change. Key findings indicates that practices like conservationtillage, agroforestry, and other climate-resilient approaches enhances agricultural sustainability andresilience. The results highlight the urgent need for further investigation and policy incentives toencourage adaptive behaviour and provide food security in the presence of climatic variability.Thus, the conclusion of these findings encourages the widespread uptake of climate-smart practicescoupled with early warning mechanisms to reduce climatic risks effectively.
Acclimatory responses of seed pretreatment to modulate organic acid production associated with Krebs’ cycle in NaCl-stressed legumes
Authors: Chatterjee P , Biswas S , Pal B , Biswas A K
Published: January 2025

Salinity hampers stand establishment of legumes at early growth stages that affect their yield. Seed pretreatment is an indispensable method for boosting tolerance to abiotic stresses and raising seed performance under salinity. Present study was aimed to evaluate whether seed pretreatment with mild dose of NaCl (sodium chloride) triggers ameliorative effects on growth and respiratory cycle of Cajanus cajan and Vigna mungo under salinity. Seedlings were raised hydroponically from non-pretreated and pretreated seeds under NaCl stress for three weeks. Non-pretreated Cajanus and Vigna seedlings exhibited reduction in root and shoot growth under salinity. Salt stress affected activities of enzymes associated with respiratory cycle specifically dehydrogenases, increased organic acid accumulation which played a versatile role to maintain cellular functions by balancing excess ions. Regardless of NaCl dose, the efficacy of seed pretreatment proved substantially beneficial to modulate the toxic effects of NaCl in both the test varieties. Lower perturbations of Krebs’ cycle in pretreated seedlings caused lower accumulation of organic acids due to prior seed acclimation conferring improved defence to thrive under salinity. Conclusively, since seed pretreatment contributes to minimize salt stress in both the test varieties, present study could be extended to legumes grown on soil to confirm the eco-friendly, cost-effective and ameliorative role of seed pretreatment to combat salt stress in saline prone agricultural fields.

Published: January 2025

Objectives: Hyperimmune - convalescent plasma transfusion appears to be a great resource in the current SARS-CoV-2 coronavirus pandemic and seems to be one of the few effective treatment modality available. However, its efficacy is variable and dependent on antibody/plasma volume concentration. Methods & Results: This single center analysis from a forefront COVID-19 Italian hospital in 43 convalescent plasma donors demonstrated that this variability in neutralizing antibody (NAB) levels is related to the harvesting period after SARS-CoV-2 recovery and interestingly, on blood group type. Specifically, the optimal plasmaferesis time point was approximately two weeks post test negativation with a significant drop in NAB plasma levels (112±102 vs 60±26.9, p=0.003) observed at 30 days. In contrast, no correlation between NAB and IgG plasma levels was observed over time (r=0.48.). Subgroup analyses demonstrated that NAB levels where higher in male (115.1±110.7, p=0.0001) and in blood group AB (200±138.6, p=0.036) donors while group A patients (81.2±82.7, p=0.062) had the lower levels of NAB concentration. Conclusion: This analysis demonstrated that male patient with a AB blood group plasma which was donated within three weeks of convalescence contains the highest therapeutic levels of antibodies and these patients should be actively recruited to become donors.
Study of the cone of sums of squares plus sums of nonnegative circuit forms
Authors: Dressler Mareike , Kuhlmann Salma , Schick Moritz
Published: January 2025

In this article, we combine sums of squares (SOS) and sums of nonnegative circuit (SONC) forms, two independent nonnegativity certificates for real homogeneous polynomials. We consider the convex cone SOS+SONC of forms that decompose into a sum of an SOS and a SONC form and study it from a geometric point of view. We show that the SOS+SONC cone is proper and neither closed under multiplication nor under linear transformation of variables. Moreover, we present an alternative proof of an analog of Hilbert’s 1888 Theorem for the SOS+SONC cone and prove that in the non-Hilbert cases it provides a proper superset of the union of the SOS and SONC cones. This follows by exploiting a new necessary condition for membership in the SONC cone.

The structure particulars of amorphous Ge2Sb2Te5 thermally evaporated on glass
substrates, as well as films annealed at temperatures of 500 and 700 K have been studied
by the considering of experimentally established facts obtained from X-ray analysis and
Raman spectroscopy measurements. The Debye-Scherrer and Williams-Hall methods were
applied to the X-ray diffraction data for estimate the size of crystallites, interatomic
distances, dislocation density and structure distortion degree. The features of heat
treatment effect on numerical values of the above quantities at a given temperatures have
been established. The analysis of the spectral distribution of Raman scattering was
measured at light frequencies between 40 ÷ 300 cm-1
. The rather extended nature of the
identified bands suggests the presence of several vibrational modes, leading to the
appearance of individual spectral bands. To determine the vibrational modes, a reduced
intensity was constructed from the experimental Raman spectrum data and the Gaussian
approximation was applied to the latter. Having a mind the results of published works, the
vibration modes existing in the samples obtained immediately after the process of layer
application were determined, as well as the chemical nature and structure elements
corresponding to these modes forming the amorphous matrix. The vibration modes in
crystallized layers after heat treatment at the given temperatures were determined, as well
as the chemical bonds and structural units forming their local structure.

As a potential substitute for antibiotics, cadmium sulfide and zinc oxide nano-particles
(CdS and ZnO NPs) were created using laser ablation and a straightforward chemical
process, respectively. Target of cadmium sulfide, deionized water, zinc nitrate, and sodium
hydroxide were used as precursors. Different characterization techniques were used to
characterize the CdS and ZnO NPs. X-ray diffraction was used to confirm that the CdS
and ZnO had polycrystalline structures with average crystalline sizes of 54.16 nm and
29.23 nm, respectively. The ZnO particles were densely packed 2D curved nanopetals
with a diameter of 51.65 nm, whereas the CdS particles were shown to consist of particle
agglomerates with spherical and semi-spherical morphologies with a diameter of 34.53 nm
from FE-SEM images. According to AFM, the average grain size of ZnO and CdS was
37.51 nm and 79.64 nm, respectively. The purity of the produced nano-particles was
validated by FTIR. ZnO has an estimated energy gap of 4.25 eV and CdS of 2.5 eV.
Regarding Gram-positive and Gram-negative bacterial strains and fungal strains, the CdS
and ZnO NPs exhibit pertinent anti-microbial sensitivity. Compared to S. epidermidis and
Klebsiella, the produced nano-particles were shown to have stronger anti-bacterial activity
against S. aureus and E. coli, with a larger zone of inhibition. The Candida, however,
recorded a higher value of 39mm.

Carbon paper, as a key component in proton exchange membrane fuel cells (PEMFCs), had
attracted much attention due to its corrosion resistance, electrical conductivity and
mechanical strength as well as gas permeability. The incorporation of carbon nanofibers
(CNFs) into carbon paper can further enhance its electrical conductivity and other properties.
Herein, prepared carbon paper precursors (CPP) via wet papermaking and optimized the
process through resin impregnation and hot pressing. The addition of CNFs, particularly at
10 %, significantly improved electrical conductivity and mechanical properties, reducing
resistivity by 23.9 % and maximizing tensile strength of 36.97 N·m/g. The sequence of
CNFs application and resin impregnation, specifically the spray-after-impregnation (S-I)
method, was crucial for achieving these enhancements. Our findings offer a strategy for
fabricating high-performance carbon paper, crucial for PEMFC efficiency and durability.

Researchers utilized NaBH4 to gently modify alkali lignin, resulting in L-Sx-ty-Pz with high
hydroxyl value and decolorization, significantly enhancing the strength of composite films
with cellulose nanofibers (CNF). Without strict pH control, the hydroxyl content of the
modified lignin reached as high as 9.14 mmol/g. The CF/L-S1-t120-Pu composite film
achieved a maximum stress of 45.33 MPa, representing a 116% and 77% increase compared
to pure CNF and crude alkali lignin composite films, respectively. The reduction effect of
NaBH4 imparted transparency to the film, broadening its applications. Additionally, the
film's excellent antibacterial and flame-retardant properties provide strong support for
industrial utilization.

In this work, ZnO thin films were exposed to 80 keV Fe+1 ions at different fluences (1 x
1013, 1 x 1014, 5 x 1014, 1 x 1015 ions/cm2
). With the help of X-ray diffraction (XRD),
scanning electron microscopy (SEM), spectroscopic ellipsometry (SE), and the four-point
probe technique, we were able to measure the structural and surface morphology, optical,
and electrical properties of both untreated and irradiated ZnO thin films. X-ray diffraction
research showed that crystallite size was diminished from its pristine level with the fluence
of 1 x 1013 ions/cm2
, but that crystallite size increased along with the ion fluence, resulting
in higher levels of crystallinity in the thin films. SEM images of a ZnO thin film exposed
atthe fluence of 5 x 1014 ions/cm2 revealed acicular patterns on its surface. The electrical
resistivity of ZnO thin film decreases as the fluence of ion increases. Consistency between
the findings supports the idea that the observed behavior is due to the confined heating effect
generated by ion irradiation of the thin films.

An ASEAN Transboundary Haze Court: Why Does it Matter and How is it Possible?
Authors: Kusniati Retno , Helmi Helmi , Rapik Mohamad , Permatasari Bunga , Jaderojananont Peerapon
Published: January 2025

As a form of state responsibility as required by the ASEAN Agreement Transboundary Haze Pollution (AATHP), Indonesia and Thailand have provided sanctions to be imposed to the perpetrators of the forest and land fires. However, the national laws or legal instruments on this matter work only domestically and fail to overcome the effect of the domestic forest and land fires which potentially produce transboundary haze pollution. This paper proposes that the ideas of soft law of the AATHP and the non-intervention of the ASEAN Way should be reconsidered in dealing with transboundary haze pollution and a special regional court has to be made as a central authority to impose sanction upon the perpetrators of forest and land fires that cause the transboundary haze pollution. Using a comparative case study, this article evaluates the state responsibility and the implementation of the AATHP ideas in Indonesia and Thailand and put forward the arguments and the possibilities for installing a special court for transboundary haze pollution. The results demonstrate that, due to its regional needs and institutional and legal norms, ASEAN needs a different model of regional court compared to Uni-European’s one.

Published: January 2025

The level of corruption crimes that are committed in today's society is growing from year to year, and it is accompanied by other types of criminal activity, such as the concealment of assets that result from corruption in other countries. In order to eradicate a variety of crimes that have a transnational character, particularly corruption, one of the actions that can be made is to take assets that have been developed due to corruption in other countries. This can be done through Mutual Legal Assistance. Regulations about MLA have been enacted due to the passage of Law Number 1 of 2006, which discusses providing mutual assistance in criminal matters. Mutual Legal Assistance is considered to be the first stage of law enforcement, particularly in the process of recovering state assets that have been stolen as a result of corruption crimes. As a result, cooperation with other nations is required, such as the cooperation between Indonesia and Australia, which aims to return state assets that have been stolen due to corruption crimes hidden in Australia.

The study of the distribution of microplastics in the geological component of marine ecosystems, in particular, the detection of the amount of pollution by plastic material, the determination of its types, origin and routes of movement is a relevant direction of research of the scientific world community in recent decades. The SSI "MorGeoEcoCenter of the National Academy of Sciences of Ukraine" within the framework of the international project "Developing Optimal and Open Research Support" for the Black Sea (DOORS) (https://www.doorsblacksea.eu/) conducts research on the distribution of microplastics in the bottom sediments of the shelf areas of the western parts, as well as coastal deposits of the northwestern part of the Black Sea. An important component of the research is the process of sample preparation for laboratory analyses, which determines the qualitative extraction of microplastic particles with preserved shape and size from the mass of bottom sediments. The practice of microplastic’s research in the laboratory of SSI "MorGeoEcoCenter" made it possible to develop equipment for non-contact mixing of bottom sediment samples. The experimental separator created on the basis of a grinding machine allows continuous mixing of sediments, ensuring constant movement of the container with the substance in the horizontal plane and its permanent oscillations with an optimal frequency in the vertical. The non-destructive physical characteristics of oscillations allow the unlimited use of the device for the term that is necessary for the reliable separation of the mass of the bottom sediments of the sample into particles that are unitary in nature and their effective separation by density characteristics in the solution. The size of the grinding platform and the availability of additional elements guarantee the ability to work with containers of various volumes, shapes, and sizes. Further special experimental studies will determine the degree of efficiency of the device and open up the possibility of its involvement in practical work to improve the efficiency of laboratory processing of natural substances and improve the quality of research results.

The publication discusses one of the methodological aspects of microplastic research in bottom sediments with the involvement of a field experiment with the selection of natural matter by various means. Sampling was carried out within the western part of the Black Sea by specialists of the State Scientific Institution "MarGeoEcoCenter of the National Academy of Sciences of Ukraine" during research under the international project "Developing Optimal and Open Research Support for the Black Sea" in 2022. As a result of the performed field and laboratory work, new data were obtained, which allow us to conduct comparative characteristics of the quality of bottom sediment sampling for the presence of microplastics with such devices as a multicorer and a bottom scoop, and to find out the potential loss of actual material by one of the devices in comparison with another. This allows not only to improve the selection method and prevent the loss of actual material, but also to form the appropriate coefficients of quantitative conversion in the event that it is necessary to involve both options for obtaining samples of bottom sediments within the framework of one task. In general, the work carried out allows to gain important practical experience in the field of research of microplastics in the geological environment of sea basins.

A generalized model of the phase field is developed for modelling the dynam-ics of microstructural transformations in iron-based Fe–Cr–Al alloys by tak-ing into account the dynamics of equilibrium point defects. Dynamics of the processes of formation and growth of chromium-enriched precipitates of α′-phase during long-term annealing of solid solution is studied. An influence of both the concentration of alloying elements and the annealing temperature on the dynamic and statistical characteristics of the growing precipitates is analysed. The scaling dynamics of the average size of precipitates, their number as well as the universality of size distribution are shown. A redistri-bution of elastic stresses under mechanical loading in the form of shear de-formation is investigated within the framework of the nonlinear theory of elasticity. The influence of both the composition and the annealing tempera-ture on the mechanical properties of the alloy is analysed.

The effect of doping with scandium, zirconium, and hafnium on the thermal stability of high-strength wrought Al–Zn–Mg–Cu (of 7XXX series) alloys at 80°С for 100 hours is investigated. The study is performed on rods produced by a two-stage hot extrusion of 1500 g ingots. As shown, the doping with scandium and zirconium has improved the hardness and strength character-istics due to the occurrence of two ensembles of dispersed precipitates: in-termetallics η′-phase (MgZn2) and Al3(Sc1−xZrx) particles coherently bonded with the aluminium matrix. As proved, in the 7XXX alloy, which is addi-tionally doped with the (Sc + Zr + Hf) complex, the composition of nanosize precipitates based on Al3Sc intermetallic compound includes zirconium and hafnium. The alloying of the base alloy with the complex (Sc + Zr + Hf) stabi-lizes the structural state of the alloy and, after holding at 80°С, no signifi-cant changes in the size and distribution of strengthening particles are ob-served. This makes it possible to obtain high strength characteristics of Al–Zn–Mg–Cu alloys with a high level of plasticity at long-term holding at 80°С.

Shape-memory alloys belong to the functional materials, which exhibit shape memory, superelasticity and high damping-capacity phenomena. Cu–Al–Mn shape-memory alloys remain of particular interest as they show good ma-chinability and are much cheaper than nitinol. In addition, their functional performance is quite attractive as well. The present paper is dedicated to the changes in shape memory and internal friction induced by the grain-size re-duction in low-temperature cast Cu69.26Al25.86Mn4.88 alloy.

Krakow is one of Poland’s most important cultural heritage treasures, but many tourists only visit the city’s iconinc and world-famous monuments. Far fewer people take a walk around the entire Old Town, visit the former suburbs of Krakow, not to mention the parts further afield. The reason for this can be attributed, among other things, to an insufficient number of marked tourist routes that would, on the one hand, encourage people to visit these areas and, on the other hand, be a motivating factor for better exposition of valuable landscape forms. Such measures are already becoming increasingly popular in Poland, also in rural areas, where newly designed tourist routes serve to exhibit even the smallest forms of cultural heritage and encourage tourists to visit a given region. This paper presents student designs of tourist routes running along the northern and southern sides of Krakow’s Old Town, together with the result of the pre-design research on which they were based. From a didactic point of view, they provided an opportunity to sensitise future landscape architects to the beauty and necessity of protecting and displaying Poland’s cultural heritage, both within and outside historic cities. When made available to the public, these routes can encourage people to visit more places of interest in and around the old town of Krakow, with a particular attention to the various forms of urban greenery, as well as their better exhibition and, in turn, the revalorisation of non-existent or forgotten landscape elements.

Los países en América Latina miran con preocupación como los índices de obesidad y enfermedades cardíacas, cáncer, afecciones respiratorias y diabetes afectan gran parte de la población, generando un cargo en dinero al sistema de salud importante, por lo que los gobiernos siguiendo las recomendaciones de la Organización Panamericana de la Salud (OPS), han decidido por vía legislación tributaria aumentar el valor de las bebidas azucaradas para tratar de reducir el consumo de este tipo de productos, los cuales son una de las causas de los índices de obesidad y los diversos tipos de enfermedades mencionadas. El presente artículo tiene como propósito realizar un análisis del impacto en el consumo de bebidas azucaradas luego de la implementación de impuestos saludables en el caso de México, Ecuador, Chile y Perú, durante la investigación se utilizó una metodología con enfoque cualitativo, y la técnica de análisis de datos con rastreo bibliográfico en donde se obtuvieron datos de fuentes gubernamentales sobre el consumo de bebidas azucaradas en periodos pre y post implementación del impuesto, la principal conclusión indica que aunque si hubo una disminución del consumo en estas bebidas, esta no es significativa y es necesario aumentar las tarifas para obtener mejores resultados.
