Published: December 2024

Withania coagulans is a well-known medicinal plant reported to possess numerous biological activities. However, the plant remains underutilized compared to other medicinal plants due to lack of clinical and analytical studies. In the present study, in vitro biological activities of oil extracted from seeds of W. coagulans were studied along with synthesis and characterization of catalyst from residue obtained post oil extraction. The extracted oil exhibited DPPH-radical scavenging activity, protein denaturation activity and in vitro -? amylase inhibitory activity. These activities were comparable to the corresponding activities of standard compounds indicating diverse medicinal potential of the oil. The residue obtained post oil extraction was utilized for synthesis of catalyst. The synthesized catalyst was characterized to identify the nature of the catalyst. Catalyst synthesized from residue was found to be silica-based catalyst, crystalline in nature and EDX mapping revealed catalyst to comprise of C, O, Na, Si, P and Ca. Interpretation of results obtained depict potential utilization of W. coagulans for diversified traditional as well as industrial application.
Integrated pest management strategies for the invasive orchid blossom midge (Contarinia maculipennis Felt.)
Authors: Minnu VJ , Allwin L , Elanchezhyan K , Manivannan MI , Rajinimala N 
Published: December 2024

Orchid blossom midge (Contarinia maculipennis Felt.) is a tiny Cecidomyiid fly that infests cut flowers such as orchids, jasmine, and tuberose. As a small insect, the midge can adapt to various environments, evolving new survival strategies, including overcoming climatic barriers. Midge has recently been identified as a major pest for cut-flower cultivators, posing substantial harm, especially to tuberose, reducing their attractiveness to customers. In orchid farms, it infests and damages the flower buds of Dendrobium, especially during the early stages, resulting in substantial yield loss. Abiotic conditions, in conjunction with orchid species, facilitate midge's access to its host plants; yet gaps in comprehending these relationships have impeded research. A major concern is its infestation within flower buds, which has prompted scientists to prioritize management strategies. Despite efforts toward sustainable management, controlling this pest remains a challenge. This review covers the host range, geographic distribution, molecular taxonomy, biology, seasonal occurrence, the influence of lunar phases on adult emergence, volatile studies, and various approaches for managing the orchid blossom midge.

Published: December 2024

Abstract
This article aims to investigate the tensile properties of carbon fibre-reinforced plastic (CFRP) and self-reinforced polypropylene (SRPP) composites used in both experimental and numerical investigations. The experimental study evaluated the tensile strength, tensile strain, and modulus of CFRP and SRPP composite laminates under tensile loading. Finite element modelling was employed to predict and validate the tensile properties of these composites. CFRP and SRPP laminates were manufactured using the hot compression technique and stacked through the hand lay-up technique. The results revealed that CFRP with a unidirectional pattern provided a higher tensile strength (1,162 MPa) than the twill pattern (288 MPa) with nominal strain values of 0.017 and 0.013 in the CFRP-based system, respectively. It was observed that the results of CFRP and SRPP composites provided a good agreement between experimental and numerical investigations. Moreover, the failure behaviour of CFRP and SRPP laminates was evaluated and compared with experimental and numerical results. Furthermore, practical applications of CFRP and SRPP composites for lightweight parts are presented.
Expressing anger on Mexican X/Twitter: the case of Uber customer complaints
Authors: Powell Hebe , Placencia María Elena 
Published: December 2024

Abstract
This paper examines anger expression in a corpus of 66 customer service complaints posted to the Mexican X/Twitter account of the online cab company, Uber. Specifically, building on work on emotions and (im)politeness as well as work on service-related anger episodes, it focuses on how these complainers signal their anger, and how these emotional expressions are related to rapport management orientation. Adopting a qualitative perspective, we observed complainers in this corpus expressing anger explicitly (using specific lexical choices such as profanities), implicitly (for example, asking rhetorical questions with semantic connotations of anger), or indulging in anger behaviours (threatening retaliatory behaviour). The majority of these strategies would be considered rapport challenging, however, certain more constructive, rapport enhancing strategies were also observed: for example, complainers portrayed themselves as approachable using medium specific in-group slang or provided means to open a dialogue to solve whatever problem they were complaining about.
Activity budget and feeding patterns of the Red Giant Gliding Squirrel (Petaurista petaurista, Pallas 1766) in the Eastern Himalayan rainforest of India
Authors: Chatakonda Murali Krishna , Chetia Hiranmoy , Kumar Awadhesh 
Published: December 2024

Abstract
Limited research appears on the Red Giant Gliding Squirrel (Petaurista petaurista) in general and the current study presents the first comprehensive analysis of its activity patterns, feeding behaviour, and food selection of the species in the tropical rainforests of Indian Eastern Himalayas. Surprisingly, the Red Giant Gliding Squirrel exhibited a predominantly frugivorous diet in the current study and deviates from the previously documented florivorous tendencies of Asian gliding squirrels, emphasising the crucial role of the local ecological context in understanding dietary patterns within mammals. When it comes to activity budget, the species spent the majority of the time in feeding followed by resting and travelling. The majority of the activity happened to be in the terminal canopy of the trees.

Published: December 2024

Abstract
An overlap of ranges of Nilgiri langurs (Semnopithecus johnii Fischer, 1829) and tufted gray langurs (Semnopithecus priam Blyth, 1844) in the Western Ghats resulted in the formation of mixed-species groups (MSGs) with a notable presence of brown morphs and significant changes in group composition and population dynamics. Our study investigated the composition of MSGs and examine the vegetation in their ranges across the Western Ghats. We identified three new locations with MSGs in the Nilgiris and southern Western Ghats predominantly found in deciduous forests (∼50 %), at an average altitude of 621.01 m asl. The mean group size of MSGs was 10.9 ± 4.49SD The geographic variation in the abundance of Nilgiri and tufted gray langurs, driven by their ecological adaptability and dispersal patterns, provides important insights into their ecological niches in the Western Ghats.
Fuzzy neural network with backpropagation for fuzzy quadratic programming problems and portfolio optimization problems
Authors: Khan Izaz Ullah , Khan Raja Muhammad Usama Ali , Ullah Mehran , Shah Muhammad Shahbaz 
Published: December 2024

Abstract
The study aspires to adopt back propagation fuzzy neural networks to solve fuzzy quadratic programming problems. The main motivation behind proposing a back propagation neural network is that it can easily adjust and fine-tune the weights of the network from the error rate obtained at the previous layer. The error rate customarily called the loss function is the dissimilarity between the desired and predicted outputs. The chain and power rules of the derivative allow back propagation and successively update the weights of the network to perform efficiently. Thus, the gradient of the loss function is calculated by iterating backward layer by layer but one at a time to reduce the difference between the desired and the predicted outputs. The research flow is such that first of all the quadratic programming problem is formulated in a fuzzy environment. The problem with fuzzy quadratic programming is formulated as a lower, central, and upper model. The formulated models are then solved with backpropagation fuzzy neural networks. The proposed method is then implemented in the capital market to identify the optimal portfolio for potential investors in the Pakistan Stock Exchange. Six leading stocks traded on the stock exchange from Jan 2016 to Oct 2020 were taken into consideration. At all three levels (lower, central, and upper), the results of identifying the best investment portfolio for investors are consistent. The proposed three models identify the investors to invest in ATHL, MCB and ARPL, whereas, the remaining three IGIHL, INIL and POL are not desirable for investment. In all three cases, the convergence is obtained at 475 iterations which is faster than the previously conducted studies. Moreover, another advantage of the proposed technique is that it brings an improvement of 28.77% in the objective function of mean variance optimization MVO model.
Instability of interactives: The case of interjections in Gorwaa
Authors: Andrason Alexander , Harvey Andrew 
Published: December 2024

Abstract
This article studies the morpho-phonetic instability of interactives through the example of Gorwaa interjections. The analysis of 91 constructions demonstrates that, in Gorwaa, interjections are highly unstable: the number of idiolectal interjections is much larger than that of shared interjections, and the interjections of both sets form clusters – spaces composed of constructions connected through the family resemblance of a formal and functional type. The formal modifications are achieved through prolongation, replication, alternation (of phones/features), and concatenation, and are related to changes in meaning and the polysemy inherent to interjections. Overall, the interjective category is modeled as a dynamic/fuzzy network of related (formally/functionally) constructions. The grammatical profiles of shared and idiolectal interjections are identical and corroborate the validity of the prototype of interjections. The refinements proposed include a preference for [j] over [w], a tendency toward (extra-)high tones and decreasing tonal patterns, the use of gutturals and clicks as the most common extra-systematic sounds and that of clicks as genuine consonants in non-click languages, the iconic foundation of some interjections and their relationship to babytalk, as well as the close relationship of interjections with the |A| place of articulation.
Estimating the Growth Impact of Economic Transformation in Qatar
Authors: Kularatne Chandana , Miyajima Ken , Muir Dirk 
Published: December 2024

Abstract
Qatar’s economic growth and improvements in living standards have been underpinned by a state-led, hydrocarbon-intensive growth model. More recently, Qatar has been undergoing an economic transformation toward a growth model that is more dynamic, knowledge-based, sustainable, and led by the private sector. It will be guided by the recently published Third National Development Strategy, which aims to achieve the National Vision 2030. This paper suggests key reforms to achieve this goal, quantifying their potential impact on the real economy using a semi-structural, general equilibrium model that includes Qatar. Model simulations suggest substantial benefits from labor market reforms, particularly those that would increase the participation of skilled expatriate workers. They also suggest large growth gains from reforms for the business environment, including those that improve access to finance.

Published: December 2024

Abstract
SrPd2Sn2 was synthesized by a reaction of the elements in a sealed tantalum tube in an induction furnace followed by annealing in a muffle furnace to increase crystallinity. The polycrystalline sample was studied by powder X-ray diffraction: P4/nmm, a = 464.00(7), c = 1,058.4(4) pm and V = 0.2279 nm3. The CaBe2Ge2-type structure was refined from single-crystal X-ray diffractometer data: a = 464.09(4), c = 1,059.64(8) pm, wR = 0.0507, 307 F
2 values and 17 variables. The single crystal shows small defects (95.9(5) %) on the Pd2 site and 73(5) % Sn2/27 % Pd3 mixing on one 2c site. The refined composition of the single crystal is SrPd2.23Sn1.73. The palladium and tin atoms form a three-dimensional, covalently bonded [Pd2.23Sn1.73] network with short Pd–Sn distances (263.3–271.4 pm). The two crystallographically independent palladium atoms in the network have tetrahedral and square pyramidal tin coordination, respectively. Within the [Pd2.23Sn1.73] network the strontium atoms fill larger cavities. The strontium atoms are coordinated by nine palladium and nine tin atoms.

Antecedentes: A pesar de su gran diversidad y la grave amenaza a la que están expuestos, los pastizales templados han recibido escasa atención.
Pregunta: Este estudio examina la biodiversidad de paisajes y taxonómía en los pastizales templados de Oaxaca.
Especies estudiadas: Flora vascular.
Sitio de estudio y fechas: Los pastizales volcánicos (PV), calcícolas (PC) y sabanas de encino (SE) del norte de Oaxaca entre 2021 y 2022.
Métodos: Tras delimitar los tres sistemas realizamos colectas, describimos la vegetación y discutimos su estado de conservación.
Resultados: Los PV y PC son los más diversos. En los PV, la diversidad se ve favorecida por el pastoreo, cuya ausencia promueve la invasión por plantas exóticas y pérdida de especies. Los PC han sufrido graves impactos debido a la agricultura, el sobrepastoreo y la plantación de pinos. Las SE son las menos diversas, aunque las menos muestreadas, y albergan especies importantes para su conservación. En total se documentaron 857 especies de plantas vasculares (aunque los datos indican que esto es una subestimación considerable), siendo el segundo pastizal más diverso de Norteamérica y comprendiendo 25 % de las especies del Valle de Tehuacán-Cuicatlán en 0.7 % de su superficie. Las familias más diversas fueron Asteraceae, Poaceae, Fabaceae, Lamiaceae y Euphorbiaceae. El 37 % de las especies son endémicas de México, algunas especies microendémicas (3) y 26 amenazadas. Además, se descubrieron tres nuevos taxones.
Conclusiones: Nuestros resultados subrayan la importancia de conocer y conservar las praderas intertropicales templadas de México ante la rápida destrucción que enfrentan.
«Hay muertos que no hacen ruido y son más grandes sus penas»: coplas sentenciosas en el Cancionero folklórico de México
Authors: Gómez Estrada Grissel 
Published: December 2024

In this article I will analyze the so-called «sententious couplets» collected in the Cancionero folklórico de México, which constitute a kind of pseudo-philosophical knowledge, enunciated through lyrical resources such as metaphors and sentences. Likewise, based on the elements with which they are constructed, these couplets can be divided into: 1. Coplas that show stereotypes (the brave and aggressive coastal man, the treacherous woman, the loving mother and the crafty Indian), which, in general, are formed through comparisons. 2. Couplets that touch on universal themes (suffering, the past, love, etc.). The latter are divided according to the literary devices they use: a) couplets with a proverb and b) couplets with metaphor. 3. Couplets that contain advice.
Oralidad: tradicionalidad, popularidad y transterritorialidad
Authors: González Aurelio 
Published: December 2024

This paper reviews the concept of orality, intersecting with traditionality, popularity, and transterritoriality. It examines how Spanish romances are repurposed in the American context, highlighting geographical relocations that diverge from original thematic units. This transterritoriality complements folklore geography’s unifying principles. The study illustrates cultural transmission’s dynamic nature, showing how literary forms like Bernal Francés and broadsheets adapt to new environments and traditional oral life. These transformations involve new forms and channels of cultural expression. By exploring these changes, the paper highlights the interplay between geographical relocation and cultural recontextualization, emphasizing the continuity and innovation in evolving oral traditions.

Authors: Gupta Seema , Satyawali V , Shukla Sanjeev 
Published: December 2024

In India, T2DM is a major health problem due to its rising prevalence and associated complications. The role and mechanism of leptin and insulin in the etiopathogenesis of type 2 diabetes mellitus have been studied and reviewed in varying ethnic populations. However in the Kumaun region of Uttarakhand studies regarding the association of leptin and insulin in type 2 diabetes are lacking, for this the present study was conducted. A total of 100 subjects, including fifty known T2DM patients and fifty healthy Age, Gender [Manish1] and BMI matched controls were[Manish2] enrolled in this cross-sectional study. Anthropometric and biochemical parameters including leptin, insulin, fasting glucose, HbA1c, and lipid profile were estimated in all the subjects by standard protocols. Higher leptin levels (p&#60; 0.001) were observed in diabetic cases as compared to healthy controls. A significant and positive correlation of leptin was observed with HOMA IR (r=0.346, p&#60;0.001), waist circumference (r=0,482, p&#60;0.01), and dyslipidemias in diabetic subjects. However, a better and strong correlation was observed in diabetic cases as compared to healthy controls. High leptin levels are associated with insulin resistance and dyslipidemia in diabetic cases in this region.
