Published: December 2024

Abstract
We conducted the present study in two freshwater lakes in the Mysore district of Karnataka, India, from December 2023 to May 2024, with the aim of evaluating the diversity, relative abundance, and feeding guilds of avifauna in Giribetta and Hadinaru lakes. The “point count” method was used to evaluate the species composition of birds. A total of 5,790 individuals, representing 106 species from 18 orders and 48 families, were recorded. Four species were in the near-threatened category: Painted Stork (Mycteria leucocephala), Black-headed Ibis (Threskiornis melanocephalus), Oriental Darter (Anhinga melanogaster), and Spot-billed Pelican (Pelecanus philippensis), while the others were of least concern. In terms of species richness, Giribetta Lake had 87 species belonging to 18 orders and 42 families, as compared to Hadinaru Lake, which had 86 species from 16 orders and 40 families. The two areas had similar species composition, with a Sorenson index of 76.3% and a Jaccard index of 61.7%, which indicates that the species diversity is fairly similar across the habitats. Based on the diet and foraging habitat, the recorded bird species were classified into eight major feeding guilds, which revealed a higher abundance of carnivorous and insectivorous birds, followed by omnivorous, granivorous, frugivorous, nectarivorous, herbivorous, and mixed guild types. It is expected that this study will provide a preliminary database for the waterbirds of this area, useful for further research and assessment.

Abstract
The avifaunal diversity assessment is a valuable ecological tool, providing a significant measure for assessing the quality and quantity of various habitats. Karsog is located in Mandi district of Himachal Pradesh, India, in the Pir Panjal Himalayan range. Avifaunal study was conducted on a monthly basis in the Tehsil Karsog from December 2023 to June 2024. The study revealed the presence of 91 bird species, spanning over 63 genera, 38 families, 12 orders. The Order Passeriformes was the most diverse with 64 species, while Bucerotiformes and Strigiformes were represented by one species each. The Muscicapidae, with 12 species, was the dominant family in the study area. Analysis of data on relative abundance showed that of the 91 species recorded, 23 species (25.27%) were very common, 27 species (29.67%) were common, 26 species (28.57%) were uncommon, and 15 species (16.48%) were rare. Among the documented avifauna, 2 species, the Alexandrine Parakeet and the Himalayan Griffon are Near Threatened species as categorized by the IUCN Red List (2024). Assessment of data on feeding guild shows that, out of 91 species, 2 species (2.19%) are granivores, 3 species (3.29%) are carnivores, 11 species (12.08%) are omnivores, 17 species (18.68%) are insectivores and 58 species (63.73%) have varied type of feeding habits. It shows that 22 species (24.17%) have a narrow feeding guild meaning that they rely on limited type of food resources. Further analysis of data on the population status reveals that 17 species (18.68%) have declining population trend as per the IUCN global population trend assessment. This emphasizes the importance of implementing conservation strategies in the area under investigation.

Authors: Kawalkar Dhanusha , Manchi Shirish S. , Quadros Goldin 
Published: December 2024

Abstract
The current study aims to comprehend the population status and distribution of the Indian Swiftlet (Aerodramus unicolor, family: Apodidae) using primary and secondary data. We acquired the population data from the secondary literature and presence data from open source (GBIF.org). We conducted surveys to document the breeding and foraging locations of the species in the Western Ghats, West Coast and Offshore islands of Maharashtra. After estimating the population, we used the presence data to create a model predicting species distribution in current and future scenarios. The Indian Swiftlet’s current distribution is from Southwest Maharashtra to Kerala and Sri Lanka. In future, the changing climate might restrict it to the southern Western Ghats and some pockets in Sri Lanka. Burnt Island, home to the largest known colony, deserves conservation attention. We recommend population surveys and immediate conservation efforts to ensure the survival of the Indian Swiftlet endemic to India and Sri Lanka.
Migration and wintering of the Mistle Thrush (Turdus viscivorus) in SE Hungary
Authors: Bozó László 
Published: December 2024

Abstract
The migration and wintering of the Mistle Thrush (Turdus viscivorus) is the least known of the other common nesting thrushes in Europe. It is also an understudied species in Hungary, detailed studies having been carried out nearly 50 years ago. The aim of the present study was to summarise the data on migration and wintering of this species that have been collected over the last 20 years in Kevermes, southeastern Hungary. There is no breeding population of the species either here or in the surrounding area. The species was observed on 371 of the 2,807 days of field observations. The first individuals typically arrived in the second week of October, but there are also data from late September and early October. Its migration is characterized by several peaks. In spring, it was still migrating intensively in the first half of April, with the last individuals leaving the area by the end of the month. In recent years, they have appeared earlier in the autumn and left later in the spring, which may coincide with the increasing breeding population of the species in Hungary. The number of individuals observed was higher in spring than in autumn and winter, similar to the situation in other parts of the country. The number of birds was high every second or third year. The number of observations in the same seasons of different years showed different patterns as well as the autumn observations did not allow any conclusions to be drawn about the number of observations later in winter and spring. The most important food was the common hackberry (Celtis occidentalis), which was protected against the Fieldfares (T. pilaris). Comparing the two species, the migratory patterns were basically similar, but the seasonal abundance of the two species differed in certain years.

Published: December 2024

Abstract
The first breeding site of Blue-cheeked Bee-eater (Merops persicus) in Peninsular India was observed in the Andivillai saltpans of Kanniyakumari district, Tamil Nadu. We found a total of 28 breeding burrows distributed into three subsets in the stretch of 30 m. Among 28 nests, 16 were active and 12 were inactive/unused. The active nest-tunnels have a mean tunnel length of 1.53±0.53 m and nest-mouth diameter of 9.93±1.48 cm. While the females excavated tunnels and started brooding males were guarding the colony. The male very often fed the female brooding inside the nest till the hatchlings appeared, and later both parents were observed feeding their chicks during the day. The chicks were first observed peeping out of the tunnels on 22 August 2023. At the end of September few juvenile birds were seen flying along with the adults foraging in the open sky. The Blue-cheeked Bee-eater is considered a passage migrant and winter visitor to the northwestern part of India and vagrant in Southern India, but this study confirmed its breeding in Southern India. Additionally, the study provides baseline information on the breeding ecology of the species in India.

Published: December 2024

Abstract
The Little Owl (Athene noctua) is a widespread nocturnal raptor whose diet has extensively been studied. In the Mediterranean, a tendency towards increased ingestion of insects has been highlighted, but this tendency still needs more empirical validation. Here, we provide data on the autumn diet of Little Owls in an arid area in southern Tunisia. We analyzed 621 pellets from 30 different territories and identified 4,267 prey items, with insects being by far the most ingested prey. However, based on biomass, the diet was more evenly distributed across the identified prey categories. Vertebrates accounted for 63% of the biomass ingested, while the remaining part of prey composition was almost equally shared between insects and arachnids. The importance of arachnids looks like a characteristic dietary trait of Little Owls in south Mediterranean deserts, where arachnids represent a main component of the community of potential prey. In summary, our findings highlight the great food opportunism of the Little Owl due to its capability of adapting its diet to the availability of potential prey.

Published: December 2024

Abstract
Bonelli's Eagle is an endangered species with little information on its ectoparasites. We studied their chewing lice (Phthiraptera: Amblycera, Ischnocera) infestations by visually searching the plumage of 64 wild and captive specimens. Three different species were identified: Degeeriella sp., Colpocephalum impressum and Laemobothrion maximum. This is the first case of Laemobothrion maximum on Bonelli's Eagle described. We also observe its haematophagous behavior. Due to the low prevalence of infestations, no alterations in the host health are described.

The Levitical Psalms of Book III: Intensifying Paradoxical Perceptions of the Divine Presence
Authors: Nathan Clayton J. 
Published: December 2024

Abstract
In Book III of the MT Psalter (Psalms 73-89), all of the psalms, save for one (Psalm 86, a Davidic poem), are Levitical. Building on recent approaches that emphasize a royal, Davidic frame to the whole Psalter, this essay makes the case that the Levitical psalms of Book III contribute to the major theme of intensifying paradoxical perceptions of God’s presence, rooted in three supportive sub-themes: (1) the presence of God is perceived as distant, and even absent; (2) the presence of God is perceived as proximal, via the theme of God’s sovereign rule over creation; and (3) the presence of God is perceived as proximal, via the themes of holy space and Zion. This analysis is worked out through four major groupings of Levitical psalms in Book III: (1) the framing psalms (73, 89); (2) the lament psalms (74, 77, 79, 80, 83, 85, 88); (3) the praise psalms (75, 76, 84, 87); and (4) the historical or prophetic psalms (78, 81, 82).

Published: December 2024

Abstract
For ensuring a greener and low carbon future; renewable energies sources such as solar energy stands out as a prominent solution for generating sustainable and clean electricity due to its accessibility, abundance and numerous benefits. The use of solar panel also called as photovoltaic systems has more importance in the world for their ability to convert sun irradiation into electricity while they have significant drawbacks like the nonlinearity of Pv panel. The efficiency and performance of Photovoltaic (PV) systems can be influnced by various factors, like climate fluctuations during the day. Therefore, it is so important to optimize the power capturing from PV panels. To optimize the energy created by photovoltaic modules, it is necessary to carefully select a DC-DC converter with MPPT control. This guarantees that the maximum power is extracted from the solar power plant and sent to the demand side in less time and with greater effectiveness. This paper introduces a super twisting sliding mode control technique for achieving maximum power point tracking (MPPT) in a photovoltaic (PV) system. The Single Ended Primary Inductor Converter (SEPIC) is proposed as a superior alternative to the conventional boost dc-dc converter, as it enables the extraction of the highest possible power from the photovoltaic panels array. Upon doing a thorough comparison of the suggested control with the P&O algorithm in various scenarios using the MATLAB/SIMULINK tool, it was found that the provided STC (Synchronous Tracking Control) for the SEPIC converter demonstrates greater efficiency and reduced oscillation around the Maximum Power Point (MPP).

Published: December 2024

Abstract
This paper investigates the impact of parasitic effects on the performance of on-chip planar spiral inductors for DC-DC converter applications, focusing on three geometries: square, hexagonal, and octagonal. Detailed electromagnetic simulations in MATLAB are employed to analyze the frequency-dependent behavior of key parasitic components, including ohmic resistance (Rs), substrate resistance (Rsub), oxide capacitance (Cox), and substrate capacitance (Csub) across a frequency range of 1 GHz to 10 GHz. The study reveals that the octagonal spiral inductor outperforms the others, demonstrating a 29% reduction in ohmic resistance at 1.5 GHz compared to the square geometry and achieving the highest substrate resistance, which helps reduce current leakage. Additionally, the octagonal inductor exhibits the lowest parasitic capacitance and a high-quality factor, peaking at 30 at 4.2 GHz. These results underscore the significant impact of inductor geometry on minimizing energy dissipation and electromagnetic interference, positioning the octagonal spiral inductor as a compelling choice for enhancing efficiency and miniaturization in DCDC converter designs.

Published: December 2024

Pea (Pisum sativum L.) is the second most important cool-season food legume in Ethiopia after faba bean, both in terms of production area and annual yield. The study comprises 13 advanced field pea genotypes that were evaluated in a randomized complete block design with four replications across four different environments during two consecutive main cropping seasons (2020–2021). The primary objectives were to identify a field pea genotype with a reliable, high grain yield that could be subsequently released as a new cultivar for farmers in specific areas of Ethiopia. A combined analysis of field pea grain yield revealed a significant difference (P < 0.01) between genotypes and environments, suggesting that the genetic composition of the genotypes varied and the environments were distinct. The average grain yield ranged from 1614 kg/ha to 2412 kg/ha, with a mean of 2032.69 kg/ha. Genotype G13 had the highest average grain yield (2412 kg/ha) compared to the standard check varieties Bilalo (2190 kg/ha) and Bursa (2100 kg/ha), indicating its potential for developing adaptable varieties suited to specific environments. This outcome may aid breeders in choosing the most appropriate cultivars for particular environments, resulting in higher field pea yields and productivity. Nonetheless, the research also indicates that to create broadly adaptable and climate-resilient varieties, it is crucial to carry out trials in various locations and across multiple years.

Published: December 2024

Approaches are presented to predict dynamic ditching loads on aircraft fuselages using machine learning. The employed learning procedure is structured into two parts, the reconstruction of the spatial loads using a convolutional autoencoder (CAE) and the transient evolution of these loads in a subsequent part. Different CAE strategies are assessed and combined with either long short-term memory (LSTM) networks or Koopman operator based methods to predict the transient behavior. The training data are compiled by an extension of the momentum method of von Karman and Wagner, and the rationale of the training approach is briefly summarized. The application included refers to a full-scale fuselage of a DLR-D150 aircraft for a range of horizontal and vertical approach velocities at 6 deg incidence. Results indicate a satisfactory level of predictive agreement for all four investigated surrogate models examined, with the combination of an LSTM and a deep decoder CAE showing the best performance.

Published: December 2024

Natural convection inside a bounded space is often vital for designing the flow dynamics of high-energy dense systems, namely, the thermal management systems of electronic devices, nuclear reactor cores, crude generation, and so on. In the present exploration, numerical investigation of buoyancy-motivated thermal energy flow patterns inside an inclined quadrantal enclosure has been conducted. The curved wall, bottom wall, and left wall have null heat flux, higher temperature, and lower temperature, respectively. The influence of the inclination angle [Formula: see text] has been critically scrutinized with the support of the flowfield (stream function), temperature distribution (isotherms), Nusselt number [Formula: see text], and entropy generation within the enclosure. [Formula: see text] is varied from 15 to 60 deg under dissimilar Rayleigh numbers ([Formula: see text]) and Prandtl numbers ([Formula: see text]). One crucial insight deduced from the study is that the power of circulation roll alters radically with the inclination angle and [Formula: see text]. The local heat transport rate has been found to increase with [Formula: see text] and decrease with an escalation in [Formula: see text]. The cavity tilted at 30 deg with the horizontal direction has been found to be the optimal design condition due to the maximum average Nusselt number along both the walls and the total value of entropy generation.
