Published: April 2024

Porous substrates act as open “interfacial reactors” during the synthesis of polyamide composite membranes via interfacial polymerization. However, achieving a thin and dense polyamide nanofilm with high permeance and selectivity is challenging when using a conventional substrate with uniform wettability. To overcome this limitation, we propose the use of Janus porous substrates as confined interfacial reactors to decouple the local monomer concentration from the total monomer amount during interfacial polymerization. By manipulating the location of the hydrophilic/hydrophobic interface in a Janus porous substrate, we can precisely control the monomer solution confined within the hydrophilic layer without compromising its concentration. The hydrophilic surface ensures the uniform distribution of monomers, preventing the formation of defects. By employing Janus substrates fabricated through single-sided deposition of polydopamine/polyethyleneimine, we significantly reduce the thickness of the polyamide nanofilms from 88.4 to 3.8 nm by decreasing the thickness of the hydrophilic layer. This reduction leads to a remarkable enhancement in water permeance from 7.2 to 52.0 l/m

Neutrophils are primed for neutrophil extracellular trap (NET) formation during diabetes, and excessive NET formation from primed neutrophils compromises wound healing in patients with diabetes. Here, we demonstrate that trained immunity mediates diabetes-induced NET priming in neutrophils. Under diabetic conditions, neutrophils exhibit robust metabolic reprogramming comprising enhanced glycolysis via the pentose phosphate pathway and fatty acid oxidation, which result in the accumulation of acetyl-coenzyme A. Adenosine 5′-triphosphate-citrate lyase-mediated accumulation of acetyl-coenzyme A and histone acetyltransferases further induce the acetylation of lysine residues on histone 3 (AcH3K9, AcH3K14, and AcH3K27) and histone 4 (AcH4K8). The pharmacological inhibition of adenosine 5′-triphosphate-citrate lyase and histone acetyltransferases completely inhibited high-glucose-induced NET priming. The trained immunity of neutrophils was further confirmed in neutrophils isolated from patients with diabetes. Our findings suggest that trained immunity mediates functional changes in neutrophils in diabetic environments, and targeting neutrophil-trained immunity may be a potential therapeutic target for controlling inflammatory complications of diabetes.

Published: April 2024

A key requirement for future multibeam broadband satellite communication systems is the ability to flexibly adjust beam capacity according to changes in business distribution, in order to meet time-varying business requirements. Beam hopping technology provides an efficient solution to achieve the efficient use of frequency resources and power resources. At the same time, the use of beam hopping makes the beam hopping of satellite payload need to match the business signals of ground signal stations, bringing about the need for synchronization of beam hopping between satellite and ground. On the basis of analyzing the basic principles and key technologies of hopping beam, the paper analyzes the synchronization problem of satellite to ground hopping beam, proposes a signaling-assisted fast synchronization method of hopping beam for satellite to ground synchronization, and conducts simulation analysis of synchronization performance.

Authors: Чекан В.Л. , Пилецкая А.А.
Published: April 2024

Альвеолярная саркома мягких тканей – редкое агрессивное злокачественное новообразование, поражающее преимущественно мягкие ткани головы и шеи, неопределенного гистологического происхождения со склонностью к сосудистой инвазии и отдаленным метастазам. Обращает на себя внимание преимущественно молодой возраст заболевших с преобладанием женского пола. Область головы и шеи является наиболее часто поражаемой областью у детей, причем наиболее распространены поражения орбиты и языка. Длительное бессимптомное клиническое течение часто приводит к поздней диагностике и несвоевременному началу лечения. Это новообразование требует тщательной клинической, рентгенологической и гисто-патологической оценки для постановки правильного диагноза. В данной статье мы представляем случай альвеолярной саркомы мягких тканей у 9-летней пациентки без клинических проявлений, прошедшей химио- и таргетную терапию, успешное хирургическое лечение с последующей лучевой терапией. В послеоперационном периоде осложнений не отмечено, признаков рецидива опухоли в отдаленном сроке наблюдения у пациентки нет.

Alveolar soft tissue sarcoma (ASPS) is a rare aggressive malignancy affecting mainly the soft tissues of the head and neck, of undetermined histological origin with a propensity for vascular invasion and distant metastases. The predominantly young age of the patients with predominance of females attracts attention. The head and neck region is the most frequently affected area in children, with the orbit and tongue being the most commonly affected. A prolonged asymptomatic clinical course often leads to late diagnosis and untimely initiation of treatment. This neoplasm requires careful clinical, radiologic, and histopathologic evaluation to make a correct diagnosis. In this article, we present a case of ASPS in a 9-year-old patient without clinical manifestations, who underwent chemo- and targeted therapy, successful surgical treatment followed by radiation therapy. There were no complications in the postoperative period, no signs of tumor recurrence in the long- term follow-up of the patient.
Sustainable Aquaculture, what should we consider?
Authors:   Centro de Investigación y Desarrollo Tecnológico en Materia Agrícola, Pecuaria, Acuícola y Forestal, Peña-Herrejón Guillermo Abraham,
Published: April 2024

In recent decades, aquaculture has played a crucial role in global food security by meeting the increasing demand for high-quality animal protein. Mexico engages in aquaculture across 23 of its 32 states, producing 351,002 tons of aquaculture products in 2021. However, disparities exist between large and small producers due to financial constraints, technological limitations, and the impact of climate change. Despite aquaculture's contribution to meeting protein demands, sustainability concerns persist. The constant increase in aquaculture demand, coupled with the generation of waste and negative public perceptions, presents challenges. Key issues include parasites in farms, antibiotic use, sourcing aquaculture feed, nutrient release, waste accumulation, and the impact on wild populations and introduction of non-native species. The article proposes solutions for sustainable aquaculture, focusing on recent advancements. Various approaches are discussed, including integrated control programs involving chemical, biological, and mechanical methods, proper antibiotic management, exploration of alternative protein sources, and the reduction of excess nutrient release and waste in natural ecosystems through integrated approaches like agroaquaculture and integrated multitrophic aquaculture

Published: April 2024

Crises such as the COVID-19 pandemic have radically
transformed the way businesses operate around the world.
Particularly MSMEs, as they were severely affected by this
crisis. In Mexico, 1.6 million of these establishments closed, and
the rest were forced to adapt quickly to the sanitary restrictions
imposed due to the pandemic. Some of the measures
implemented by MSMEs to survive the pandemic were homeoffice and online sales, for which the use of digital tools was
indispensable. The objective of this research was to identify
which digital tools were used by MSMEs to survive the
pandemic so that they are prepared to face future crises. The
research was quantitative and descriptive, a questionnaire was
applied to 100 MSMEs on digital tools used in business
operations. Regarding the results, it was found that the most used
digital tools are social networking platforms, among which
WhatsApp, Facebook, and Instagram stand out in areas such as
sales, marketing, and internal communication. In addition, the
most used digital tools for payments are electronic transfers,
Clip, and Mercado Pago.

Tuberculosis renal
Authors:   , Strassera Miguel Ángel
Published: April 2024

Es una enfermedad que ocupa un lugar preponderante dentro de las quirúrgicas.-En efecto, las lesiones T.B.G. renales son generalmente, unilaterales al comienzo y en virtud a lo cual se desprende que el diagnóstico precoz es de importancia capital. Así, pues, el conocimiento de la T.B.G. renal es de indudable interés práctico. Además debemos tener presente que no hay ciertamente un verdadero síntoma patonogmónico para su diagnóstico. El método más positivo para confirmarlo, es la inoculación de orina de un enfermo al cobayo, lo cual tampoco es estricto en virtud a que un enfermo de T.B.C. y no renal, por cierto, que cursa con bacilemia, puede eliminar bacilos por vía renal y nos daría como una tuberculosis renal positiva sin serlo. La T.B.C. renal es, generalmente, parte de una enfermedad sistemática y generalizada.

Scénarios schématiques de la vie et de la narration
Authors: Neklioudov Sergei Iou.
Published: April 2024

On peut distinguer trois cas de correspondances différentes entre les « scénarios schématiques » et le domaine narratif folklorico-littéraire : 1. La narration constitue la projection de la « dramaturgie de la vie » (une telle projection n’est évidemment ni directe ni complète) ;2. La structure de l’univers des personnages et la structure événementielle du narratif influencent la formation des « scénarios de la vie », en conditionnant l’apparence morphologico-compositionnelle de l’un et de l’autre ;3. La coincidence de la « dramaturgie de la vie » et de la « dramaturgie de la narration » s’explique par le fait qu’elles ont des sources communes ; ces sources pourraient être les modèles mentaux de la tradition, qui dictent à un homme des « règles de comportement » d’une part, et qui s’incarnent dans la narration folklorico-littéraire d’autre part. Le « scénario schématique » possède une structure événementielle, situationnelle et actantielle. À cette structure correspond un certain niveau d’interprétation qui souvent la lie directement à la conscience religieuse et mythologique ; une telle conscience — compte tenu du fait qu’une conceptualisation globale de tous les aspects de la vie humaine caractérise le mythe — englobe, par sa nature même, les « blocs interprétatifs » pertinents pour pratiquement tous les précédents événementiels. Le « scénario schématique » est donc lié au domaine des croyances et concepts actuels, lié aussi aux systèmes de valeurs et normes éthiques, etc. ; il est possible de reconstituer nombre de ces croyances, concepts, valeurs et normes à l’aide de l’histoire vécue qui nous occupe. D’ordinaire, ces interprétations ne représentent pas le fond neutre des événements, mais un élément actif et dynamique qui agit directement sur le développement de ces événements.
Le mythe, un fondement de la fonction idéologique de la science-fiction ?
Authors: Périer Isabelle
Published: April 2024

Cet article se propose d’explorer la manière dont la présence du mythe dans la littérature de science-fiction est intimement liée à la dimension idéologique et critique de ces œuvres. La démarche adoptée part d’une analyse mythocritique des textes pour aboutir à une mythanalyse permettant d’établir un lien entre les mythes analysés et les grands questionnements que pose l’accélération technoscientifique des xxe et xxie siècles. Cette démarche s’appuie sur l’exemple d’un corpus de textes science-fictionnels limité à l’œuvre de Dan Simmons afin de montrer que celle‑ci, par son substrat mythique, problématise la question de la technoscience dans son rapport à l’histoire, au développement de l’humanité et à la question de l’éthique
Le corps imaginaire et l’alimentation
Authors: Adam Véronique
Published: April 2024

L’article étudie comment l’humain peut être défini dans les rapports créés dans l’imaginaire entre le corps et l’alimentation. En s’appuyant sur des traités de médecine et de cuisine du Moyen Âge au xviie siècle, des essais d’humanistes et les travaux d’anthropologues, d’historiens et de sociologues contemporains, on découvre comment l’acte même de manger permet de définir et construire les frontières du corps humain et un imaginaire de l’alimentation : la nomination de l’aliment et la charge sémantique des métaphores empruntés à l’alimentation définissent une éthique de l’humain et sa vision du corps humain et animal. Une approche médicale complète cette étude linguistique et montre que le fonctionnement des limites extérieures et internes du corps humain se modèle sur la représentation de l’aliment et de ses effets paradoxaux, bénéfiques et pathologiques. Enfin, le corps social du mangeur est délimité par la distance qui le sépare de l’aliment et le lieu assigné à l’animal destiné à être mangé.
Murakami et les fractures de la corporéité. Vers une représentation aporétique de l’individuation
Authors: Fantin Grévost Aurélie
Published: April 2024

La plupart des romans et des nouvelles de Murakami traitent du rapport à l’existence et de la construction de l’individu. Le corps, en conséquence, est alors mis en question, en tant que moyen d’accès au monde et comme manifestions de l’individu. Ceci entre particulièrement en résonance avec la culture japonaise en raison de sa propension à considérer l’individu comme particule du groupe. Par ailleurs, une question en particulier est suggérée par Murakami : le lien entre corps et esprit. La corporéité défend alors son existence propre, sans contredire la volonté, mais pour parvenir à communiquer avec autrui et pour accéder à une forme d’universel. Dislocation entre imaginaire et réalité, conflits intimes tout autant que d’inspiration mythologique, sont les nœuds des romans étudiés : Kafka sur le rivage, La Fin des temps, L’Éléphant s’évapore. Les romans de Murakami imposent aux lecteurs d’envisager la corporéité comme un carrefour entre croyances mystique, désir et mémoire.
Figurer l’invisible : l’exemple d’Anish Kapoor
Authors: Vial-Kayser Christine
Published: April 2024

Les œuvres du sculpteur anglo-indien Anish Kapoor mettent en doute la matérialité du réel et la réalité des objets, de l’espace, du spectateur lui‑même. Elles le désignent comme une illusion et pointent vers une réalité invisible située au‑delà, ou en deçà, ou au cœur même du visible. L’article explore la nature de cette réalité cachée que les œuvres nous donnent à voir ou à pressentir. Il interroge en outre les mécanismes phénoménologiques mis en branle par les œuvres qui conduisent le spectateur à douter du réel, à se confronter à cet invisible et à le nommer.
CHILD PROTECTION IN MALAYSIA: ASSESSING THE EFFICACY OF FOSTER CARE FROM A LEGAL PERSPECTIVE
Authors: Misni Muhammad Daniel , A. Kadir Nadhilah
Published: April 2024

Foster care serves as a crucial support system for children in need of care and protection in Malaysia who cannot live with their biological families due to issues such as neglect, abuse, or abandonment. This article examines the concept of foster care, its legal implementation, and challenges. By scrutinizing existing legislation, the paper aims to identify areas for improvement to enhance the effectiveness of foster care as part of the child protection system in Malaysia. The foster care system in Malaysia is primarily governed by the Child Act 2001 and managed by the Social Welfare Department in providing family-based care, especially for abandoned children. This article employs a qualitative study, revealing challenges and limitations within the existing legal framework. The findings indicate that there is no specific law governing foster care in Malaysia. Therefore, the article emphasizes the need to enhance the effectiveness of foster care legislation by increasing resources and support for foster parents, implementing standardized training programs for them, strengthening monitoring and evaluation mechanisms, and encouraging cooperation and information sharing among relevant agencies. This is to ensure positive outcomes and long-term welfare for children in foster care in Malaysia.

In response to the issues of missed and repeated planting during the operation of the chain-spoon type potato planter in China, as well as the low recognition rate for missed planting and the difficulty in identifying repeated planting using existing detection methods, an innovative Potato Planter Missed and Repeated Planting Detection System has been designed. This system is built with a PLC as the lower-level controller and an industrial computer as the core, incorporating the YOLO object detection algorithm for detecting missed and repeated plantings during the operation of the potato planter. Using the YOLOv7-tiny object detection network model as the core, and combining model training with hardware integration, the system performs real-time detection of the potato seed situation within the seed spoon during the operation of the potato planter. It can quickly distinguish between normal planting, missed planting, and repeated planting scenarios. By incorporating the working principles of the planter, the system designs a positioning logic to identify the actual coordinates of missed and repeated planting locations when a lack or excess of planting is detected. This is achieved through the positioning module, enhancing the system's capability to accurately obtain coordinate information for actual missed and repeated planting positions. The system was deployed and tested on a 2CM-2C potato planter. The results indicate that the detection accuracy for missed and repeated plantings reached 96.07% and 93.98%, respectively. Compared to traditional sensor detection methods, the system improved the accuracy of missed planting detection by 5.29%. Additionally, it successfully implemented the functionality of detecting repeated plantings, achieving accurate monitoring of quality-related information during the operation of the potato planter.

Authors: PAZIUK Vadim , HUSAROVA Olena , BANDURA Valentyna , FIALKOVSKA Larysa
Published: April 2024

The paper examines the intensification of drying apple slices to low residual moisture content. It is proposed to use an energy-efficient multi-stage mode of convective drying at 80/60 °C and a combined multi-stage mode with IR radiation and IR convective heating (100 W) + 60 °C / 60 °C. The paper presents the temperature and kinetic curves and changes in drying speed for the studied dehydration regimes. A formula was obtained for determining the total duration of the process of drying apple slices using a combined method, and a dependence of the Rebinder number for the studied dehydration modes was constructed. Based on the experimental data analysis and generalization of research results, a method of determining the drying intensity based on the average moisture exchange and the average temperature of material heating per minute, at the first stage of drying and during the entire drying time, was proposed for the first time. The efficacy of the proposed modes is confirmed by a reduction in drying duration 1.9 times compared to the stationary mode at a coolant temperature of 60 °C. The obtained dried product is characterized by high recoverability (78–80%) and appropriate organoleptic properties.

Cellulose is the most plentiful biopolymer available in the world, and is a natural, biodegradable as well as inexpensive resource for biomaterials. Herein, a cellulose-based superabsorbent hydrogel (CHCCA) was prepared by crosslinking carboxymethyl cellulose (CMCNa) and hydroxyethyl cellulose (HEC) with citric acid, and its micro-heterogeneity and micro-rheological properties were explored by diffusing wave spectroscopy (DWS). The mean-square displacement (MSD) of microspheres imbedded into CHCCA hydrogels prepared at five concentrations was compared. At very low concentration, of 0.1wt%, the CHCCA hydrogel exhibited nearly homogeneous behavior, with slight heterogeneity. The heterogeneity became larger as the CHCCA concentration increased. It was also revealed that the high-frequency viscoelastic moduli magnitude at 0.1wt% CHCCA can be expressed by |G*(ω)| ∝ ω, which is characteristic of a viscoelastic fluid-like behavior. The magnitude of high-frequency viscoelastic moduli for 0.3 wt% and 0.5 wt% CHCCA can be described by |G*(ω)| ∝ ω3/4, which is characteristic of a semi-flexible polymer. The high-frequency viscoelastic moduli magnitude for 1.0 wt% and 1.5 wt% CHCCA described by |G*(ω)| ∝ ω1/2, was characteristic of a flexible polymer. Our results identified unique CHCCA property changes that occurred with changes in concentration, providing new insights for CHCCA derived hydrogels that will be useful in developing new CHCCA applications.

Safety evaluation of a newly designed polymeric drug delivery system (DDS), with/without the addition of active pharmaceutical ingredients (APIs), is now mandatory for their regulatory approval for human use. Hence, Salvia spinosa seed mucilage/hydrogel (SSH) was treated with methacrylic acid (MAA) to synthesize a composite hydrogel (SSH-co-MAA). Acute oral and acute dermal toxicity studies of the SSH-co-MAA for API delivery were ascertained following OECD guidelines 420 and 402, respectively. Moreover, an ocular toxicity study was also performed and analyzed through Draize scale. Animals of two species, rodent (rat) and non-rodent (rabbit), were divided into four groups. Group A of both rats and rabbits was assigned as control and remained untreated. Meanwhile, groups B, C, and D were labelled as treated groups and received a single dose of SSH-co-MAA, i.e., 0.05, 0.3 and 2 g/kg body weight of the animal. During 14 days after the treatment, animal monitoring was done for behavioral changes, food and water intake, adverse effects, and mortality. All animals remained alive, with no statistically significant abnormality. Hematological and biochemical parameters of control and treated animals were analyzed after the completion of 14 days and found in harmonization. The vital organs of rats were removed to determine absolute organ weights. Histopathology of the vital organs of rats revealed normal cellular architecture, without any lesions. SSH-co-MAA was also free from dermal and ocular toxicity. The overall results of acute oral and dermal toxicity studies prove that SSH-co-MAA is safe, especially after oral administration. Hence, SSH-co-MAA can be used as a non-toxic excipient for drug delivery systems.

The encapsulation of botanical compounds (such as citronellal) can be used to increase their efficiency and stability for functionalizing textile materials. In this study, the citronellal nanocapsules (CNC) with citronella oil as the core material and isophorone diisocyanate (IPDI) as the shell material were prepared and characterized. Factors, including core-to-shell ratio, single-phase ratios, emulsification time, as well as polymerization time and temperature, were investigated to determine the optimal process for the preparation of CNC. The average particle size of the prepared CNC was about several hundred nanometers, with uniform particle size distribution. Further, composite Lyocell fibers were prepared by the wet spinning process of co-blending CNC with Lyocell spinning stock. Evaluations were made of the biological activity of CNC towards mosquitoes, as well as E. coli and S. aureus, showing excellent mosquito repelling rate, of more than 90%, and an inhibition rate of 97.72% towards S. aureus.

Unbleached cellulose from Pinus elliotti and polyethylene glycol (PEG) were used for the manufacturing of bio-based cellulose-biochar-PEG cryogels. The cryogels were prepared by the sol-gel method, where biochar was added to a cellulose/PEG suspension, and subsequently freeze-dried. Also, biochar from poultry little waste was employed as reinforcement, aiming to increase mechanical and thermal properties. The main resuls showed that, for cryogels with biochar (5.0 wt% in relation to cellulose) and PEG (5.0 wt% in relation to the cryogels mass), an increase of the compressive strength by about 30% was achieved. The thermal conductivity of the same samples with biochar reached similar results (0.041 W m-1.K-1). Therefore, the produced material has potential to be applied as thermal insulator as an environmentally friendly alternative, with the properties that meet the requirements for traditional thermal insulators.

It is well-known that energy consumption is increasing around the world on a daily basis. In the construction sector, a highly effective solution for reducing energy consumption involves exploring both modern and traditional buildings designed to adapt to climate changes. One promising approach is to use paper waste and bio-sourced materials as the basis for insulation. The purpose of this study was to improve the sustainability of buildings by using recycled waste materials that have a positive impact on the environment, people, and the economy. A novel insulating material composed of recycled paper waste and Ampelodesmos mauritanicus leaves and fibers was developed and used in non-load-bearing elements. The paper waste was transformed into pulp and mixed with the bio-sourced materials to create a composite material that exhibits excellent insulation properties. The resulting material is lightweight, durable, and cost-effective. Furthermore, different mechanical and thermal analyses were performed on specimens with varying dosage ratios. The results showed that the developed material has good thermal insulation, with a value of 0.027 W/m.K.

Permasalahan waris dan hibah masih menjadi penyebab timbulnya sengketa di masyarakat, hal ini memungkinkan terjadi karena mereka belum memahami tentang waris secara mendalam. Salah satunya yang terjadi pada masyarakat Dusun Alasmalang Desa Bondoyudo Kecamatan Sukodono Kabupaten Lumajang. Pada masyarakat Desa Bondoyudo telah biasa dilakukan pembagian harta waris ketika pewaris dalam keadaan hidup, yang mana pada dasarnya konsep pembagian waris dilakukan ketika pewaris telah meninggal dunia. Dalam pembagian harta ini mereka menggunakan akad hibah karena kondisi pewaris masih ada. Penelitian ini merupakan penelitian kualitatif, yaitu penelitian yang metode penelitiannya digunakan untuk meneliti objek yang bersifat alamiah. Penelitian kualitatif adalah penelitian yang memanfaatkan wawancara terbuka untuk menelaah dan memahami sikap, pandangan, perasaan dan perilaku individu atau sekelompok orang. Hasil penelitian menunjukkan pembagian harta dengan cara hibah kepada anak angkat di Desa Bondoyudo Kecamatan Sukodono Kabupaten Lumajang mengandung kemaslahatan karena dapat menyejahterakan orang-orang terdekat yang sangat berjasa dalam hidupnya yaitu terhadap anak angkat dan satu saudara laki-lakinya, dan dapat menunjang kehidupan orang-orang terdekatnya tersebut.

Background: The COVID-19 pandemic and the implementation of social distancing have been reported to negatively impact cardiovascular-related health behaviors. However, the effects of lifting social distancing restrictions on these health behaviors remain unclear. This study investigated public awareness and behavioral changes related to cardiovascular disease prevention after the end of social distancing.Methods: Between June 5 and June 12, 2023, 2,000 adults participated in the 2023 Cardiovascular Disease Prevention Awareness Survey in Korea. The survey comprehensively addressed sociodemographic factors, cardiometabolic disease history, cardiovascular disease concern, prevention awareness, and behavioral changes after the end of social distancing. Logistic regression analyses were performed to assess the associations between behavioral changes and sociodemographic factors.Results: Cardiovascular disease ranked as the second most feared disease (most feared, 18.0%; second most feared, 26.3%) after cancer (most feared, 42.3%; second most feared, 21.7%). Among nine cardiovascular disease prevention recommendations, stress management, being physically active, and maintaining a healthy diet were perceived as the most challenging recommendations. After the end of social distancing, there were more positive changes than negative changes in smoking, alcohol consumption, dietary habits, physical activity, and healthcare service use, whereas stress management more frequently changed negatively (40.0%) than it changed positively (19.5%).Conclusions: Positive changes in cardiovascular-related health behaviors, except for stress management, were observed after the end of social distancing. Further research is necessary to fully comprehend the impact of discontinuing social distancing practices.

Saffron Crocus sativus L. (Iridaceae) is one of the most valuable and expensive medicinal plants in the world. In order to compare the quality characteristics of saffron in Afghanistan and Iran, samples of dried C. sativus from different saffron-producing regions of Herat province (Afghanistan) and Torbat Heydarieh county (Iran) were collected in the year 2021. The experiment was analyzed in GLM format and Nested method with three replications. The samples of saffron produced from seven different districts of Herat province in Afghanistan, including Injil, Karukh, Guzara, Pashtun Zarghun, Zendeh Jan, Ghoryan, Obeh and nine saffron-producing villages (Fakhrabad, Kadkan, Nasar, Ghaleno, Feizabad, Khorgh, Abrood, Benhang, Shadmehr) of Torbat Heydarieh county in Iran were examined. The results showed that the effect of country and region (districts and villages) on the quality traits of saffron (crocin, picrocrocin and safranal) was significant. Moreover, the comparison of the mean values indicated the presence of significant differences in the qualitative characteristics of saffron among the different investigated villages of Torbat Heydarieh. The saffron produced in Afghanistan had the highest amount of crocin (on average 279.1 ɷ 440nm) and picrocrocin (on average 101 ϕ 257nm), while the highest value of safranal (on average 34.2 θ 330nm) was observed in saffron samples produced in Iran. The highest amount of the above quality traits belonged to the saffron of Zendeh Jan Herat region 5 (Af5, crocin: 303 ɷ 440 nm, picrocrocin: 106 ϕ 257 nm, safranal: 33 θ 330 nm), while the five Torbat Heydarieh villages had the lowest quality of saffron (Ir5, crocin: 164 ɷ 440nm, picrocrocin: 71 ϕ 257 nm, safranal: 34 θ 330 nm). In the comprehensive analysis of saffron-producing regions in Afghanistan and Iran, in terms of the qualitative attributes (crocin, picrocrocin, and safranal) it was evident that regions 1 to 6 in Herat, Afghanistan (Af1, Af2, Af3, Af4, Af5, Af6) and the Abrood village of Torbat Heidarieh, Iran (Ir7) formed a distinct cluster, demonstrating superior quality compared to other regions. Furthermore, with the exception of the Feizabad village of Torbat Heydarieh (Ir5), all examined samples surpassed the saffron ISO international standard and were categorized as first-grade quality. The exceptional quality of Herat saffron from Afghanistan is likely attributable to the unique geographical features, virgin lands, and specific climatic conditions across diverse cultivation areas.
