In order to create ecologically safe food products by improving the bioecological system based on microorganisms, it is important to breed nitrogen-fixing and phosphate-mobilizing bacteria on the basis of biotechnological methods and create biopreparations from strains for use in agriculture. As a result of the influence of various abiotic, biotic and anthropogenic factors of the environment on plants, the cultivation of useful plants in agriculture causes a number of problems every day. As a result of intensive demographic growth, the population's demand for food is increasing. The decrease in productivity due to the low production of plant products may lead to the problem of food shortage in the future. As a result of the use of large amounts of synthetic fertilizers to increase productivity, soil fertility has decreased and salinity has increased. Therefore, many studies are currently focused on improving plant-microorganism-soil system mediation relationships. Representatives of other classes of plants need nitrogen fixers. Treating them with biostimulators prepared on the basis of associative and free-living AFB living in the rhizosphere allows not to use synthetic fertilizers beyond the permissible limit in the future, thus improving soil fertility and growing environmentally friendly products.

Published: January 2025

Knitted fabrics have complex and repetitive patterns, similar to fractal geometry, where fractal theory can be applied in industry 4.0 to optimize the design, production and analysis of complex and efficient textile structures.This study aims to reduce electromagnetic radiation using conductive knit fabrics patterned with fractal geometry and non-conductive knit fabrics with similar patterns. Tests included raw materials (yarn) and fabrics. The yarn was tested using FTIR and SEM, while the fabric was tested for anti-radiation reduction and aesthetics. Conductive yarns of stainless steel polyester filament were interlaced with acrylic yarn using the jacquard technique on a Stoll CMS 540 HP automatic flat knitting machine. The results showed that the conductive knit fabric patterned with fractal geometry was better at absorbing electromagnetic radiation than the non-conductive knit fabric. The radiation test was conducted with sources from smartphones and computer screens at a distance of 10 cm, 20 cm, and 30 cm, while the aesthetic test was conducted using a questionnaire. The novelty of this research lies in the application of fractal geometry motifs, which enhance the protective and aesthetic functions of the fabric, resulting in a functional textile with high visual appeal.

Published: January 2025

The use of ducks down to serve as a filler in recent years has increased. In 2015, in Canada, the well-known jacket Company Canada Goose, which uses down as a filler, became very popular, even in 2016 its sales in the US grew by 50%. But the use of down is opposed by many parties including animal welfare groups (animal welfare) who campaign “save the duck” because the use of down is considered to hurt animals. Down is taken or uprooted from living birds without being given painkillers. Some companies then implement policies to ensure that the down used does not come from raw materials that hurt poultry. However, concerns about this still arise, because consumers will not be able to ascertain whether the down-fill jacket used is from Fluff plucked from living birds or not. In previous research, Wonosobo fleece has a thermal conductivity value of 0.03 W/moK, while the thermal conductivity of poultry fleece ranges from 0.024 – 0.03 W / moK. This shows that this fleece fiber has the potential to be used as an alternative raw material for jacket filler. In addition, Wonosobo sheep fur also comes from environmentally friendly materials, the process of epilation is done without hurting the sheep itself, it is the process of epilation of sheep have a positive impact on sheep, such as eradicating fleas on sheep fur. Based on the down issue and the potential of Wonosobo fleece to be used as a jacket filler, it is necessary to innovate the manufacture of multilayer jacket material made from fleece.

Published: January 2025

Abstract: Hygiene is essential in daily life, and soap is vital for effectively cleansing contaminants and bacteria from the skin. Recent innovations in soap-making, including the development of transparent soaps, aim to enhance both functionality and aesthetic appeal. This study explores the incorporation of eco-enzyme, derived from the fermentation of kitchen waste such as fruits, vegetables, sugar, and water, into transparent antibacterial soap. Eco-enzyme contains lipase, trypsin, and amylase, which are effective in inhibiting pathogenic bacteria. The adoption of eco-enzyme not only enhances the sustainability of soap production but also promotes the efficient use of organic waste. This research conducted a laboratory-based experimental investigation to evaluate the effectiveness of eco-enzyme in the production of transparent solid antibacterial soap using palm oil. The process involved several stages: preparation of raw materials, soap production, and subsequent analysis. The results demonstrated that the soap met SNI standards with water content ranging from 12% to 17%, a pH between 9.57 and 9.81, and free fatty acids ranging from 0.9% to 1.7%. The inhibition zone for Staphylococcus aureus was 7.81 mm, indicating a moderate antibacterial effect. These findings suggest that eco-enzyme provides a bacteriostatic effect, inhibiting bacterial growth without necessarily killing the bacteria, and highlight its potential for developing sustainable and effective antibacterial products.

Authors: Wardiani Gina Rahayu
Published: January 2025

Based on the mandate of Law Number 33 of 2014 concerning guarantees for halal products, that all products circulating in the market including goods used or utilized by the public must be halal, one of which is textile and clothing products. Currently, not many textile and clothing products are halal-certified. Whereas textile and clothing products have great potential to develop their business in supporting the strengthening of the value chain in the halal industry. Halal traceability is one of the halal requirements that must be met in the manufacture of halal products, this is stated in the Halal Product Guarantee (JPH) HAS 23000. Halal traceability is also an important factor in maintaining halal integrity. There are various methods used in developing a halal traceability system. One of them is the IDEF0 method. The IDEF0 method can be used in determining plans to capture traceability information needed by internals. In addition, IDEF0's simple notation construction consisting of input, control, output, mechanism (ICOM) becomes the main strength as a communication tool that is easily understood by everyone. Therefore, this study develops a model of a halal traceability system based on critical activities that can change the halal status of a product with the IDEF0 method in the Small Medium Enterprises (SMEs) of Muslim women's clothing. Based on the results of the study, there are six critical activities that affect the halal status of products during the production process, namely, material purchasing activities, material receiving and storage activities, supply to production activities, production activities, finished product storage activities, and outgoing transportation activities.
The Symbolic Concepts of Transhumance [Kuwila] in The Kafue Flats Among the Tonga People of Mwanachingwala, Hamusonde and Mungaila in Southern Province, Zambia
Authors: Manford Michelo
Published: January 2025

This paper investigates the symbolic concepts of transhumance (kuwila) among the Tonga people residing in the Kafue Flats, specifically within the chiefdoms of Mwanachingwala, Hamusonde, and Mungaila in Southern Province, Zambia. Transhumance, traditionally seen as the seasonal movement of cattle, is reinterpreted in this study as a deeply symbolic practice, intricately connected to the social, cultural, and spiritual fabric of the Tonga community. Through a multidisciplinary lens, the study examines how kuwila serves as a rite of passage for young herdsmen, facilitating their journey of self-discovery and social rehabilitation. This practice is also explored as a means of reinforcing communal bonds and transmitting cultural values, particularly through the invocation of ancestral spirits and the use of ritualistic numbers, such as the number seven, which symbolizes completeness in both Tonga and biblical traditions. The research further analyses the role of cattle ownership as a pedagogical tool, essential for teaching responsibility and leadership to the younger generation. The herdsmen's deep attachment to their cattle is framed as a reflection of their spiritual and familial connections, with cattle often being named after ancestors to ensure protection and continuity. In addition to its cultural significance, kuwila is highlighted as a crucial practice for resource management and environmental sustainability in the Kafue Flats. The paper underscores the importance of integrating traditional knowledge with modern governance strategies, advocating for a holistic approach to managing the region’s natural resources. By bridging the gap between cultural practices and ecological management, this study contributes to a broader understanding of how indigenous knowledge systems can inform contemporary governance and sustainability efforts in Southern Zambia.

Published: January 2025

The development of Fuzzy Logic Controllers (FLC) with low error rates and cost effectiveness has been the subject of numerous studies. This paper study goals to the investigation and then implementation an FLC using the readily accessible and reasonably priced Raspberry Pi technology. The FLC used in this work has two inputs, one output, and five Membership Functions (MFs) for each input and output. The FLC goes through two processes, tweaking the MF parameters and tuning input/ output Scaling Factors. The tuning technique makes use of the Genetic Algorithm (GA). The whole set of the FLC probabilities is taken into account as the tuned FLC controller, and then transformed into a lookup table. The Center of Gravity (COG) approach is used to determine the output for the tuned FLC controller. The resulting table is converted into values of digital binary using a specific type of encoder, and then extraction of the set of Boolean functions to apply this tuned circuit. Finally, the Python 3 programming language is used to define the resultant Boolean functions on the Raspberry Pi platform, and then a decoder extracted the appropriate control action from the output. The Benefit of this method is the use of a digital numbering system to define the FLC, which is implemented on Raspberry Pi technology and allows for fuzzified high processing speed output per second. The controller speed has not been unaffected by the quantity for these fuzzy rules.

When coping strategies become the norm: household water insecurity in the Dominican Republic
Authors: Brown Hannah Sadie , Gough Katherine V. , Kayaga Sam , Longley Andrew J.
Published: January 2025

There is a growing consensus that global monitoring of water access greatly underestimates household water insecurity worldwide. Measures that overlook the intricacies of accessing water lead to an overinflated sense of progress towards universal water access. This article illustrates the complexity of household water access by revealing the causes and impacts of household water insecurity in the Dominican Republic. A mixed-methods case study approach is adopted, which combines a household survey with interviews and immersive research. Households are shown to adopt numerous strategies to cope with the fractured system of water delivery, including using multiple sources of water, storing water, sharing and borrowing water, and engaging in exchanges of social capital. Although individual activities are integral to the ongoing functioning of water infrastructure, the impact and cost of systemic reliance on these creates an unacceptably high user burden. Moreover, these strategies exacerbate household water insecurity, the very phenomenon they are employed to mitigate.

Intermediate-mass black holes (102 < M
BH < 105
M
⊙) are an open question in our understanding of black hole evolution and growth. They have long been linked to dense star cluster environments, thanks to cluster dynamics, but there are a limited number of secure detections. We leverage existing X-ray observations from the Chandra X-ray Observatory and optical catalogs from the Hubble Space Telescope (HST) as well as new radio observations from the Karl G. Jansky Very Large Array to search for any evidence of accreting black holes in young massive star clusters in the nearby galaxy M51. We find that of 44 bright (L
X > 1038 erg s−1) X-ray point sources in M51, 24 had probable matches to objects including possible associated star clusters in the HST Legacy Extragalactic UV Survey catalog, seven of which were classified as contaminants (background galaxies or foreground stars). We explore the optical properties of the remaining 17 sources, including cluster age and mass estimates, and search for radio counterparts in the 8–12 GHz band. The lack of radio counterparts to X-ray sources we know to be associated with young massive star clusters in M51 suggests that we do not significantly detect hard-state intermediate-mass black holes (IMBHs)  ~104

Authors: Li Xiang-Lin , Dai Yu-Cheng , Liu Zhan-Bo , Jiang Yu-Han , Liu Hong-Gao , Yuan Yuan
Published: January 2025

Nigroporus vinosus (Berk.) Murrill, first described from North America, was considered to be a common species in China. The existence of a species complex is confirmed through a phylogenetic analysis of samples examined. Based on morphological examination and molecular evidence, four new species are described as Nigroporus australianus, N. austroasianus, N. subvinosus and N. yunnanensis. They are characterized by pileate, effused-reflexed to resupinate, purplish, vinaceous to brown basidiomata when fresh, mostly becoming brown when dry. Nigroporus australianus is characterized by narrower basidiospores measuring 3.4–4.1 × 1.3–1.5 µm, thicker contextual hyphae measuring 3.2–6.4 µm in diam and a geographical distribution in Australia. Nigroporus austroasianus is characterized by smaller pores measuring 10–13 per mm, generative hyphae dominant in the tube trama, small basidiospores measuring 3–4.1 × 1.5–2 μm and a distribution in Malaysia and tropical to subtropical regions of China. Nigroporus subvinosus is characterized by skeletal hyphae with thin to slightly thick walls, barrel- to pear-shaped basidia, and long cystidioles measuring 10–18 µm and is common in Asia. Nigroporus yunnanensis is characterized by thinner pilei measuring 2.5 mm thick at the base, bigger basidiospores measuring 4–4.5 × 1.9–2.2 μm and is found only in Yunnan. The 2-gene (ITS+nLSU) analysis of the Steccherinaceae indicated that the four new species nested in the Nigroporus clade. The 3-gene (ITS+nLSU+TEF1) analysis of the genus Nigroporus showed that N. australianus formed a monophyletic lineage, N. subvinosus was sister to N. austroasianus and N. yunnanensis, and N. austroasianus was sister to N. yunnanensis. Furthermore, N. vinosussensu stricto is also distributed in Asia.

The aim of the current study was to evaluate the chemical profile of eight samples containing essential oil (EO) from biocultivated Rosmarinus officinalis L. from different locations and various harvesting periods. Another key point of this study was the evaluation of the chemical profile of commercial products containing EO isolated from bio Salvia rosmarinus Spenn. It was observed that the harvest period may not have a significant effect on some of the bioactive components that are present but may affect their percentage content. Furthermore, not only the time of harvesting the plant material influences essential oil component composition, but also its location may have an effect.
‘Il fiore del verso russo’? Soviet poetry, publishing and the PCI in post-war Italy
Authors: Milani Mila
Published: January 2025

In 1949, the Italian left-wing publisher Einaudi, related in varying degrees to the Italian Communist Party (PCI), published a poetry anthology entitled Il fiore del verso russo (‘The Best of Russian Poetry’), edited by scholar Renato Poggioli. The publication sparked
debate, as both the editor???s selection of poets and his preface were deemed as not fully aligned with communist ideals. This created tensions between the publishing house and the party, as well as within the publishing house itself. In 1961, Einaudi published a second anthology, of Soviet-era
poetry only, Nuovi poeti sovietici (‘New Soviet Poets’), edited by Slavicist Angelo Maria Ripellino. By this time the editors??? attitude, as well as the relationship between Einaudi and the PCI, had radically changed, as was visible in the reception of the later anthology.
This article draws on Pierre Bourdieu’s theoretical framework for its analysis of the production and reception of these literary works, and argues that, through the debates on poetry translation, Italian cultural agents sought to position themselves within both the national context of
the changing post-war distribution of power and the transnational exchanges of the Cold War. The translation of Soviet poetry becomes a lens through which we can see the micro-dynamics and contradictions that emerge in transnational cultural networks and movements.
On the behavior of geodesics of left-invariant sub-Riemannian metrics on the group $ \operatorname{Aff}_{0}(\mathbb{R}) \times \operatorname{Aff}_{0}(\mathbb{R}) $

In this paper, we study geodesics of left-invariant sub-Riemannian metrics on the Cartesian square of a connected two-dimensional non-commutative Lie group, where the metric is determined by the inner product on a two-dimensional generating subspace of the corresponding Lie algebra. It is proven that the system of equations for geodesics of such a sub-Riemannian metric is not completely integrable in the class of meromorphic functions. Important qualitative characteristics of the corresponding geodesics are found, thus proving the complexity of their behavior in general.

Acral melanoma is an aggressive subtype of melanoma which presents on palms soles and nails. It is more frequently seen in patients with Asian or African descent. It usually presents at an advanced stage due to a lack of patient awareness and diagnostic delay. Here, we report a case of an elderly male who presented with unusual nodules on the upper limb.
Dabigatran-induced Vasculitis on the Palms: A Case Report and Review of Literature
Authors: Lunge Snehal Balvant , Bindagi Anisha P
Published: January 2025

Dabigatran is one of the newer nonvitamin K antagonist oral anticoagulants and has been approved for atrial fibrillation and prevention of venous thromboembolism. Till date, very few cases of dabigatran-induced leukocytoclastic vasculitis (LCV), also known as hypersensitivity vasculitis or hypersensitivity angiitis, have been described in the literature. We present the case of a 50-year-old male with deep vein thrombosis who developed palpable purpura and petechiae over the palms after dabigatran initiation. The present case highlights dabigatran as a potential risk for LCV, the rare site of LCV over the palms, and also provides insight into management and further evaluation.

Published: January 2025

Introduction:

Pyogenic granuloma (PG) is a common benign vascular lesion, presenting as a rapidly growing papule or polyp that bleeds easily. Diagnosing PG can be challenging due to its clinical similarity to other tumors. Dermoscopy offers improved accuracy in identifying such vascular by demonstrating features. This study aims to explore dermoscopic features with their association to histopathological changes in PG in skin of color.

Materials and Methods:

A prospective observational case series study was conducted at S. Nijalingappa Medical College from January 2022 to November 2022. Patients with clinical signs of PG were included, while those with infected and oozing lesions were excluded. Demographic data, clinical evaluation, photographic documentation, dermoscopic examination, and histopathological analysis were performed. Statistical analysis was carried out using SPSS Statistics v20.0.

Results:

A total of 30 patients (13 males, 17 females) were included. Solitary red papule on face and scalp was common presentation. Dermoscopic features included reddish homogeneous areas (96.7%), white collarette (80%), white linear rail-lines (60%), hemorrhagic crust (30%), and rainbow phenomenon (30%). Dotted, linear irregular, and hairpin vessels were vascular patterns. Histopathology showed dilated blood vessels in a lobular arrangement (96.7%), hyperplastic epithelium forming a collarette (73.3%), and collagen bundles (56.7%). Statistically significant correlation was found in reddish homogeneous areas (P=0.001) white collarette (P=0.005) and white rail lines(P=0.001) with corresponding histopathological changes.

Conclusion:

Dermoscopy identifies characteristic features in PG effectively, aiding differentiation from similar lesions. The association with histopathological changes validates its diagnostic and monitoring relevance. Further studies with larger sample sizes are recommended.
Co-occurrence of Tubular Apocrine Adenoma and Syringocystadenoma Papilliferum over the Hypogastrium: A Rare Case Report

Published: January 2025

Tubular apocrine adenoma (TAA) and syringocystadenoma papilliferum (SCAP) are rare benign sweat gland tumors. To date, only 17 cases of their coexistence have been reported worldwide. A 16-year-old female patient presented with multiple linearly arranged pink pedunculated grouped papules and plaques with irregular and lobulated surfaces present over the hypogastrium region for 6 years. There was no evidence of nevus sebaceous. A complete excision of the tumor was performed. On histopathology upper dermis showed cystic invagination lined by outer columnar and innercuboidal epithelium extending downward from the epidermis with papillary projections suggestive of SCAP, and the lower dermis revealed apocrine glands lined by double-layered epithelium with luminal decapitating secretions suggestive of TAA, thereby confirming the coexistence.
A Phase-IV, Multi-centric, Open Label, Comparative Clinical Trial to Evaluate Safety, Tolerability, and Efficacy of Oral Tablets of Fixed-dose Combination of Alogliptin and Metformin Hydrochloride versus Alogliptin in the Treatment of Indian Type-2 Diabetes Mellitus Patients: CONFIDENCE Trial

Introduction:

Dipeptidyl peptidase-4 inhibitors are widely used antidiabetic drugs due to their convenient dosing, modest HbA1C reduction, and minimal risk of hypoglycemia, commonly prescribed in combination with metformin. A phase-IV, multi-centric, open-label, randomized, comparative clinical trial aimed to evaluate the safety, efficacy, and tolerability of a fixed-dose combination (FDC) of alogliptin + metformin hydrochloride versus alogliptin oral tablet in the management of Indian patients with type-2 diabetes mellitus (T2DM).

Methods:

This was a multi-center, randomized, open-label, comparative, parallel-group, phase IV clinical study. The study duration was 180 days, with follow-ups conducted at 30, 60, 90, and 180 days. Safety evaluations included assessing adverse events (AEs), serious adverse events (SAE), laboratory tests, and vital parameters. Parameters such as HbA1C, fasting plasma glucose (FPG), and postprandial glucose (PPG) were analyzed at baseline and at the end of the study. The trial was registered at ClinicalTrials.gov: CTRI/2021/11/038226.

Results:

Out of 362 enrolled patients, 344 completed the study; 166 received the FDC of alogliptin + metformin and 178 received alogliptin only. After 6 months, the mean reduction in HbA1C from baseline was − 2.07 (P < 0.001) in the FDC of alogliptin + metformin group and − 1.29 (P < 0.001) in the alogliptin group. Mean FPG decreased significantly in both groups, with a greater reduction observed in the FDC of alogliptin + metformin group (−103.65, P < 0.001). Similarly, there was a significant reduction in mean PPG in both groups, with a greater reduction observed in the FDC of alogliptin + metformin group (−143.11, P < 0.001). Out of 166, 25 (15.10%) patients experienced 10 AE in the FDC of alogliptin + metformin group and 23 out of 178 (12.90%) patients experienced 10 AE in the alogliptin group. All the reported AE were mild in severity and resolved completely. No serious adverse events were reported in either treatment group.

Conclusions:

In this study, alogliptin and the FDC of alogliptin + metformin were well tolerated, without any serious adverse events reported. These findings suggest that both treatment options are promising for managing Indian T2DM patients in terms of safety, efficacy, and tolerability.
