В работе представлены результаты исследований по разработке составов на основе керамического порошка марки ВК-95-1 для DLP 3D печати. Исследована динамическая вязкость различных составов в зависимости от методов замешивания, содержания и типа керамического порошка. Изучены параметры полимеризации керамических суспензий для составов с 60 и 70 масс. % керамического порошка. Для увеличения глубины отверждения получаемых суспензий предложено введение дополнительного количества фотоинициатора. Подготовлены образцы методом DLP 3D печати с применением различной мощности УФ-излучения. По результатам проведенных исследований установлено, что введение диспергирующей добавки в исходный порошок, позволяет снизить вязкость получаемых суспензий до 2,5 раз. Максимальная глубина отверждения составов без дополнительного содержания фотоинициатора с 60 и 70 масс. % керамического порошка составляет 120 и 140 мкм соответственно, при добавлении 0,5 масс. % фотоинициатора (по отношению к фотополимерному связующему) глубина отверждения увеличивается до 340 мкм. Микроструктура напечатанных образцов представлено равномерно распределённым в полимерной матрице керамическим без видимых дефектов и расслоений, которые могут быть сформированы в процессе 3D печати.

This paper presents the results of research into the development of compositions based on VK-95-1 ceramic powder for DLP 3D printing. The dynamic viscosity of different compositions was investigated as a function of mixing methods, content and type of ceramic powder. The polymerisation parameters of ceramic suspensions were studied for compositions with 60 and 70 wt.% ceramic powder. The introduction of additional amount of photoinitiator was proposed to increase the curing depth of the obtained suspensions. The samples were prepared by DLP 3D printing method using different UV irradiance. According to the results of the conducted research, it was found that the introduction of dispersing additive in the initial powder allows to reduce the viscosity of the obtained suspensions up to 2.5 times. The maximum curing depth of compositions without additional content of photoinitiator with 60 and 70 wt.% of ceramic powder is 120 and 140 microns, respectively, with the addition of 0.5 wt.% of photoinitiator (based on photopolymer binder) the curing depth increases up to 340 microns. The microstructure of the printed specimens is represented by uniformly distributed in the polymer binder.

Нанотермит Bi2O3/Al в смеси с газогенерирующей добавкой азодикарбонамида (АДКА), рассматривалась нами, как перспективная система для создания гибридных нанокомпозиционных материалов. В работе приведены результаты исследования скорости горения и силы взрыва нанотермитной композиции Bi2O3/Al/АДКА, где помимо изменения концентрации АДКА в системе, мы видоизменяли принципы рецептурной компоновки композиции. Показано, что введение азодикарбонамида в нанотермит Bi2O3/Al, оказывает благоприятное влияние на взрывчатые параметры композиции, так удаётся достичь повышения силы взрыва на 29 %, а скорость горения в слое 0,1 мм на 170 м/с относительно базовой нанотермитной пары Bi2O3/Al. В целом, зависимость взрывчатых параметров от концентрации АДКА в композиции имеет экстремальный характер, где пиковые значения скорости горения и силы взрыва достигаются при содержании добавки в системе - 10 и 15 % (в зависимости от рецептурно компоновки), после увеличение концентрации АДКА уже оказывает негативное влияние на исследуемые параметры – при содержании азодикарбонамида ~30 %, взрывчатые параметры композиции снижаются до уровня базовой нанотермитной системы Bi2O3/Al.

We considered Bi2O3/Al nanothermite mixed with gas-generating azodicarbonamide (ADCA) additive as a perspective system for developing hybrid nanocomposite materials. In this work, we present the results of the research on the burning velocity and explosion force of the Bi2O3/Al/ADCA nanothermite composition, where in addition to changing the concentration of ADCA in the system, we modified the prescription configuration principles of the composition. It is shown that the addition of azodicarbonamide to Bi2O3/Al nanothermite has a beneficial effect on the explosive parameters of the composition, so it is possible to achieve an increase in the explosive force by 29%, and the burning velocity in a layer of 0.1 mm by 170 m/s relative to the basic Bi2O3/Al nanothermite pair. In general, the dependence of combustion performance on the concentration of ADCA in the composition has an extreme character, where the peak values of burning velocity and explosion force are reached at the content of the additive in the system - 10 and 15% (depending on the configuration), after increasing the concentration of ADCA already has a negative effect on the studied parameters - at the content of azodicarbonamide ~30%, the explosive parameters of the composition are reduced to the level of the basic nanothermite system Bi2O3/Al.

В настоящее время среди различных видов пылеуловителей наибольшее распространение получили аппараты инерционного типа, они применяются практически на всех производствах, в том числе в металлургии, машиностроении и химической промышленности. Эффективность работы таких аппаратов зависит от многих факторов, в том числе от физико-химического состава частиц и параметров пылегазового потока. Поэтому при разработке принципиально новых конструкций пылеуловителей и модернизации существующих аппаратов необходимо оценивать влияние параметров пылегазовой среды на эффективность пылеулавливания. В данной работе с помощью современных программных средств, реализуемых метод конечных элементов, исследовано влияние запыленности газа на структуру потока в новом инерционно-центробежном пылеуловителе. Получены картины распределения скоростей потока в различных сечениях аппарата. Установлено влияние начальной запыленности газа на картину распределения скоростей. Подтверждена возможность эксплуатации инерционно-центробежного пылеуловителя в условиях высоких значений концентрации частиц дисперсной фазы в газовом потоке.

At present, among various types of dust collectors, the most widely used are inertial type devices; they are used in almost all industries, including metallurgy, mechanical engineering and the chemical industry. However, such devices have a number of disadvantages, including low efficiency under conditions of high initial dustiness of the gas flow. Therefore, when developing fundamentally new designs of dust collectors and upgrading existing devices, it is necessary to evaluate the influence of the parameters of the dust and gas environment on the efficiency of dust collection. In this paper, using modern software tools implemented by the finite element method, the influence of gas dustiness on the flow structure in a new inertial-centrifugal dust collector was investigated. Flow velocity distribution patterns in different sections of the device were obtained.The influence of the initial dustiness of the gas on the velocity distribution pattern has been established. The possibility of operating an inertial-centrifugal dust collector under conditions of high concentrations of dispersed phase particles in the gas flow has been confirmed.

Bronchial mucoepidermoid carcinoma in children is rare, the clinical manifestations are non-specific, and it is easy to be misdiagnosed as tuberculosis, pneumonia, right lung middle lobe syndrome, asthma and other diseases, delaying the time of treatment. This article reviews the medical history of 18 children with bronchial mucoepidermoid carcinoma treated by the First Affiliated Hospital of Guangzhou Medical University, summarizes their clinical features, treatment and prognosis, and concludes that pathological obstruction should be considered when children with recurrent respiratory symptoms do not respond to conventional treatment. Therefore, we recommend that any child with persistent, unexplained respiratory symptoms that do not resolve after 2 weeks of treatment undergo endoscopy as soon as possible, and once MEC is confirmed by biopsy, surgical treatment is recommended. The long-term prognosis after complete tumor resection is good, but there is still a risk of recurrence and metastasis, so long-term follow-up is recommended for the child.

Published: January 2025

Crosslinking macromolecules is an important process that aims to modulate mechanical properties of elastomers and meet desired specifications based on the application sought. The impact of crosslinking density on rubber moduli has been well established by theory, experiments and computational studies. However, several reports imply a role for the length of the sulfide bond and the attachment location. In this study, we construct all-atom models of polyisoprene (PI) networks using equilibrated precursor melts and sulfide crosslinks of a specific chemical architecture. We first examine network characteristics which follow expectations based on our random crosslinking approach. We report the presence of a substantial number of intramolecular connections formed. Thermodynamics and microscopic dynamics of the resulting networks are also probed. Comparing systems with the same number of crosslinks, we find that local mobility is most decelerated in the presence of long quaternary connections. To resolve any impact on mechanical properties we resorted to extensive characterization of moduli via equilibrium (stress-stress fluctuations) and non-equilibrium processes (constant-rate and oscillatory deformations). Both equilibrium and non-equilibrium simulations (at times/frequencies accessible to our all-atom models) confirm that quaternary linkages provide for the highest moduli with linker length holding a secondary role during moderate deformations.
Meta-analysis of Stoichiometric Changes Before and After the Critical Micelle Concentration Within Lanthanide Solvent Extraction
Authors: da Silva Garcia Leite Leonardo , Clark Aurora
Published: January 2025

A dataset derived from 35 sources was used to analyze the changes to acid:extractant and metal:extractant stoichiometric ratios as a function of aqueous acid concentration. The presence and location of the critical micelle concentration is easily identified by sharp changes to the stoichiometric ratios. This is consistent with the proportional increase in aggregate size of extractants surrounding a polar core containing extracted metals. Statistical consistency across the dataset allows for elucidation of outliers, the location of previously unreported CMC conditions, and improved CMC values relative to individual studies. Data dense vs. sparse regions of the composition space are identified and the impact this has upon meta-analysis of extraction data is discussed.
Visible-Light-Mediated Site-Selective C(sp2)–H Alkylation of Tropones Enables Semi-Synthesis of Cephafortunoids A and B and a Reconsideration of Their Biosynthesis

Published: January 2025

The synthesis of functionalized tropones constitutes an underexplored chemical space, primarily due to the intrinsic structural properties of the aromatic nucleus. This predicament has impeded extensive investigation into their potential applications in organic and medicinal chemistry. Here, we report a mild and straightforward visible-light-mediated protocol for the α-site-selective C(sp2)–H alkylation of tropones, employing unactivated secondary amines as alkylating agents. This method yields up to 88% in 41 examples, and is significantly amenable to late-stage functionalization. The utility is showcased by the effective chemical trasformation of fortunolide A to cephafortunoids A and B, representing the first synthetic entry to this unique class of C20 Cephalotaxus troponoids. Significantly, this achievement reinforces the chemical feasibility of the newly hypothesized biosynthesis involving direct methylation catalyzed by S-adenosylmethionine (SAM).
Synthesis and Characterization of Bimetallic Copper (I) Complexes Supported by a Hexadentate Naphthyridine-Based Macrocycle Ligand
Authors: Martínez-Ceberio Carlos , Fernández–de–Córdova Francisco José , Rivada-Wheelaghan Orestes
Published: January 2025

Herein, we describe the synthesis and characterisation of N,N′–di–tert–butyl–3,7–diaza–1,5(2,7)–1,8–naphthyridinacyclooctaphane and its coordination chemistry with CuI centres. The macrocyclic naphtyridinaphane ligand (tBuN6) reacts selectively with 2 equivalents of tetrakis acetonitrile copper (I) precursor, yielding the bimetallic CuI–complex [Cu2(tBuN6)(MeCN)2][BF4]2, 1·BF4. Each CuI–atom has a pentacoordinate geometry, with elongated distances with the amine N–donors (2.25 Å), in which the fifth coordination position belongs to a cuprophilic interaction with its vicinal CuI–atom (2.74 Å). Complex 1·BF4 exists in equilibrium in acetonitrile solutions with complex 2, [Cu2(tBuN6)2][BF4]2, and free [Cu(MeCN)4[BF4] due to ligand/solvent exchange. Complex 2 can be formed in high yields when tBuN6 is combined with 1 equivalent of [Cu(MeCN)4[BF4]. Both CuI–atoms remain pentacoordinate with the same Cu···Cu distance but with increased distances with the amine N–donors (2.31 Å). Ligand tBuN6, however, exhibits two different conformations in the solid structure: syn(boat/boat) for the ligand with amine N–donors attached to the CuI–centre, and syn(chair/chair) for the ligand with free amine N–donors. Complex 1·BF4 reacts with 1 equivalent of [Bu4N][Cl] generating selectively complex 3, [Cu2(μ–Cl)(tBuN6)][BF4]. The presence of the bridging Cl–atom shortens the Cu···Cu distance (2.51 Å) and increases the stability of the dicopper complex in acetonitrile solutions and solid state. Counter ion exchange of 1·BF4 with sodium tetrakis 3,5–bis(trifluoromethyl)phenyl borate (NaB(ArF)4) generates 1·B(ArF)4, which behaves similarly to 1·BF4 in acetonitrile solutions. However, in tetrahydrofuran (THF) solutions, 1·B(ArF)4 exhibits higher stability, with no observed formation of complex 2. In THF, complex 1·B(ArF)4 contains one MeCN–bridging molecule, which is described as a three-centre two-electron bonding [Cu2(μ–MeCN)(tBuN6)][B(ArF)4]2. When complex 1·B(ArF)4 is placed under CO atmosphere in THF solutions, the syn,syn biscarbonyl complex 4·B(ArF)4 [Cu2(tBuN6)(CO)2][B(ArF)4]2 is generated. This complex is sufficiently stable in solution under CO and Ar atmosphere to be characterised by NMR and IR spectroscopy, with two stretching bands observed for the CO bound to the CuI–centres at 2102 and 2088 cm–1.
Elucidating the Boundary of Intercalation vs. Sequestration in Supramolecular Polymers by Retrosynthetic Design Towards the Construction of Complex Supramolecular Systems
Authors: Bäumer Nils , Ogi Soichiro , Yamaguchi Shigehiro
Published: January 2025

Controlled social self-sorting by intercalation can offer distinct properties at the supramolecular level that go beyond the sum of its parts. Likewise, controlling narcissistic self-sorting by sequestration can induce unique system properties such as dilution-induced self-assembly. In contrast, the interface between the two extreme cases has hitherto remained underexplored and clear design rules remain elusive. Herein we demonstrate that by fine-tuning the molecular similarity of supramolecular synthons in a complex system, intricate control over concerted supramolecular equilibria can be achieved. By reducing the molecular similarity, a former intercalator can be tuned to become a strong or weak sequestrators. As a consequence, either uncommon dual supramolecular sequestration or an unprecedented competitive hybrid mechanism between sequestration and intercalation in tertiary mixtures could be demonstrated. We are hopeful that the results presented herein will contribute to the development and understanding of concerted processes in complex supramolecular systems.
Filling the gaps in the LiBr-LiOH phase diagram: a study on the high-temperature Li3(OH)2Br phase

Published: January 2025

In this paper we build on previous work to characterise a new phase with stoichiometry Li3(OH)2Br existing between ∼225 degC and ∼275 degC in the LiBr-LiOH phase diagram. Diffraction studies indicate that the phase takes a hexagonal unit cell, and theoretical mod- elingisusedtosuggestapossiblecrystalstructure. Nuclearmagneticresonancespectroscopy and electrochemical impedance spectroscopy measurements demonstrate excellent lithium- ion dynamics in this phase, with an ionic conductivity of 0.12 S/cm at 250 degC. Initial attempts to stabilise this phase at room temperature through quenching were not successful. 1 Instead, a metastable state demonstrating poor lithium-ion conductivity is found to form. This is an important consideration for the synthesis of Li2OHBr solid-state electrolytes (also found in the LiBr-LiOH phase diagram) which are synthesised by cooling through phase fields containing Li3(OH)2Br, and are hence susceptible to these impurities.
Empirical Exploration of Optimal Gating System Design for Sand Casting Process
Authors: Edlabadkar A. P. , Chaudhari S. S. , Kamble P. D. , Mankar C. , Kashyap D. N.
Published: January 2025

Purpose: This paper aims to analyse and optimise the gating system used in the sand casting process to produce drainage doors at Deepshikha Casting in Nagpur. It focuses on understanding how gate design impacts productivity and the quality of the cast, drawing attention to common defects and the role of gravity casting techniques.
Design/Methodology/Approach: This paper discusses the present gating system of Deepshikha Casting in detail to identify defects, such as sand inclusions, blow holes, pinholes, gas holes, shrinkage, and misruns. The present gating ratio and system weight assessment are thus used to suggest changes in the design to improve the process efficiency and quality of the product.
Findings: The research indicates that the existing gating system has an inappropriate gating ratio, resulting in a high rate of faults and reduced productivity. The system also weighs a lot, which deters efficiency. Improving the gating design reduces flaws, increases the quality of castings, and enhances molten metal flow.
Research Limitation: The output of the present work is limited to Deepshikha Casting alone, which is used for drainage door casting. Further research must be conducted on different casting products and technologies for a broad application.
Practical Implication: This sector of sand casting can benefit from optimising the gating system, maximising productivity and minimising casting defects, thus reducing costs and improving efficiency.
Social Implication: The environment will also benefit from efficient casting because of reduced use of resources, reduced waste, and fewer consumables. Better procedures also translate to increased production of safer products.
Originality/Value: This paper provides practical, applied solutions for optimising the gating system of sand casting. Its insights are particularly informative for a foundry working with fragile metals and using gravity casting.
Seismic Damage Assessment of Reinforced Concrete Structures: Low, Medium, and High Rises Using a Performance-Based Seismic Design Approach
Authors: Khedikar A. R. , Zameeruddin M. , Charpe P. S. , Deshmukh D. , Hirekhan S,
Published: January 2025

Purpose: The research addresses the limitations of the traditional force-based approach in earthquake-resistant design, particularly its inability to account for inelastic behaviour fully. It explores the potential of nonlinear static assessment techniques within the performance-based seismic design (PBSD) framework to provide a more accurate measure of earthquake structural performance.
Design/Methodology/Approach: This research develops a set of damage indices to quantify structural damage in moment-resisting frames (MRFs) based on engineering demand parameters obtained through nonlinear analysis. The study examines reinforced concrete (R.C.) structures of various heights, evaluating their seismic load-bearing capacity and resilience using the PBSD approach.
Findings: The proposed damage indices offer a reasonable way to quantify structural damage and enhance the understanding of the plastic collapse process. Performance-based design mainly benefits R.C. structures, improving their seismic resilience and cost-effectiveness.
Research Limitation: Accurately quantifying building damage remains challenging even with nonlinear assessment tools. Further work is required to refine these tools for more precise damage quantification in various building types.
Practical Implication:  The findings have practical implications in reducing repair costs and ensuring public safety by providing preliminary damage estimates for tall buildings. The PBSD approach also meets acceptance criteria for immediate occupancy and life safety across various seismic intensities.
Social Implication: By enhancing buildings' resilience to earthquakes, this research contributes to safer urban environments, reducing potential fatalities, economic losses, and downtime associated with earthquake-induced damage.
Originality/Value: This study provides valuable insights into performance-based seismic design and presents a practical method for quantifying structural damage in R.C. structures. The proposed damage indices and PBSD approach significantly advance the safety and cost-effectiveness of earthquake-resistant buildings.
Dystrybucjonizm jako droga wyjścia
Authors: Boruta Paweł
Published: January 2025

Przedmiot badań: Dystrybucjonizm angielski, jako projekt ustroju ekonomicznego alternatywnego dla kapitalizmu i socjalizmu (komunizmu), jest obecnie przedmiotem rosnącego zainteresowania. Koncepcja ta pozostaje jednocześnie w stosunkowo niewielkim stopniu zbadana i opisana, co widoczne jest szczególnie w Polsce. Dostępność odnoszących się do tematu zarówno źródeł, jak i opracowań na rodzimym rynku wydawniczym jest nadal wielce ograniczona. Częściowym wypełnieniem występującej tutaj luki jest pierwsze polskie tłumaczenie opublikowanej w 1938 r. serii artykułów pod wspólnym tytułem Droga wyjścia (ang. The Way Out) autorstwa Hilarego Belloca, który, wraz z Gilbertem Keithem Chestertonem, uznawany jest za kluczową postać w zakresie opracowania dyskutowanej doktryny. Przedstawiony przekład autorstwa Andrzeja Ziółkowskiego stanowi okazję do wprowadzającej w temat refleksji.
Cel badawczy: Celem wprowadzenia jest po pierwsze nakreślenie kontekstu powstawania tłumaczonego dzieła: zarówno poprzez historyczne opisanie postaci Hilairego Belloca, współpracy tego autora z Gilbertem Keithem Chestertonem oraz dziejów całego angielskiego ruchu dystrybucjonistycznego, jak i wyłożenie podstawowych cech doktrynalnych samego dystrybucjonizmu. Drugim zamierzeniem jest zrekonstruowanie cech szczególnych Drogi wyjścia (na tle wszystkich dostępnych prac konstytuujących założenia koncepcji), a także próba określenia znaczenia tekstu nie tylko dla badanej doktryny, ale również dla rozwoju współczesnej myśli politycznej, prawnej i ustrojowej.
Metoda badawcza: W badaniach zastosowana została metoda historyczno-opisowa oraz komparatystyczna. W części historycznej odniesiono się do licznych opracowań w języku angielskim oraz polskim, a w segmencie doktrynalnym przede wszystkim do dzieł Belloca, (za wyjątkiem tłumaczenia Drogi wyjścia) analizowanych w postaci wydań oryginalnych w języku angielskim.
Wyniki: Wnioskiem końcowym analizy wprowadzającej jest interpretacja Drogi wyjścia jako dzieła nie tylko wielce istotnego dla doktryny dystrybucjonizmu, ale wręcz na wiele sposobów podsumowującego i koronującego wysiłki całego ruchu działającego na rzecz ukonstytuowania tego ustroju. Jednocześnie wyniki przeprowadzonych badań pozwalają wysunąć uzasadnione przypuszczenie, że przetłumaczony traktat może stanowić cenne źródło inspiracji dla współczesnego ustawodawcy – o ile ten postawi sobie za cel możliwie szeroką dystrybucję własności prywatnej i wolności ekonomicznej.

Distribution and diversity of intertidal marine faunal species along with Maharashtra and Goa coast, India
Authors: Balakrishnan S. , Sivaleela G.
Published: January 2025

The distribution and diversity of intertidal marine faunal specimens were collected from sandy, muddy, mangrove and rocky habitats along the Maharashtra and Goa coasts, India, from June 2016 and December 2018. A total of 63 species belonging to 58 genera, 39 families, 25 orders, and 6 phyla were identified. A maximum of 39 species under the phylum Mollusca, followed by 15 species of arthropods whereas the minimum of only one species was recorded under the phyla Echinodermata and Brachiopoda. Statistical tool PAST (Ver. 1.42) was employed to calculate species diversity (H’), richness (D’) and evenness (J’). The diversity of macrofaunal groups is highly disturbed due to anthropogenic activities, but they still support rich intertidal biodiversity, which needs immediate attention for protection and conservation.

Published: January 2025

The subgenus Bombus s. str. is represented by two valid species from Indian Himalayan region viz., Bombus jacobsoni- Skorikov and Bombus tunicatus- Smith. Both species of bumblebees are widely distributed and plays a very significant role in conserving the highland ecosystems. The species including the representatives of each caste, viz., queens, workers and males were collected from different habitats of Indian Himalayan region. Sixteen morphological parameters of this sub-genus covering 2 species viz., B. jacobsoni and B. tunicatus were investigated and measured relating to their body size, tongue length and antennae, number of hamuli, fore wings, hind wings and legs. Later on, total measurements were evaluated to know the differences for the identification of their different castes viz., queen, worker and males.

Note on rare knot worm, Polygordius madrasensis Aiyar and Alikunhi, 1944 (Polychaeta, Polygordiidae) from India
Authors: Vishnudattan Naduvilakkandy , Rajakumar Jayachandran Paravanparambil , Bijoy Nandan Sivasankaran
Published: January 2025

Polygordius species is a clade of smooth bodied marine annelids, which are the main inhabitants of sandy intertidal sediments. They are well adapted for life in interstitial habitats. They have a habit of tying themselves in knots when collected, giving rise to the common name â€œknot wormâ€. Due to comparative morphological appearances among Polygordius species and its resemblance with nematodes and nemerteans made its taxonomy more challenging and required more advanced microscopic and molecular techniques. Only two species and a subspecies, primarily restricted to the south coast, have been recorded from Indian waters. This study mainly discusses the Indian species, with additional information on Polygordius madrasensis Aiyar and Alikunhi, 1944, based on Scanning Electron Microscopy (SEM) results.

Diurnal activity pattern of age-sex groups of a small and fragmented population of Blackbuck (Antilope cervicapra l.) in Western Haryana, India
Authors: Delu Vikram , Singh Dharambir
Published: January 2025

Focal sampling method (Altmann, 1974) was used to record the behavioral activities of different age sex groups of blackbuck at Badopal village site of western part of Haryana which is a natural patch devoid of true grassland and surrounded by a semi-arid agro-ecosystem with high human habitation. Twenty-four fortnightly field visits were conducted for a period of one year from December 2019 to November 2020 under four classified seasons to monitor four age-sex classes, i.e., adult male, sub adult male, adult female and sub adult female. The behavioral activities were recorded from dawn to dusk covering three phases of the day (morning (06.30h to 10.00h) noon (12.00h to 14.00h) and evening (16.00h to 19.00h)). Major behavioural categories were divided as follows: Feeding, Walking, Standing, Resting and Others. Blackbucks were reported to be most active at dawn and dusk hours. Adult male spent least time in feeding among all four studied age sex categories due to its territorial nature, whereas adult females were reported to spend maximum time (41.29%) in feeding activity followed by sub adult female, sub adult male and adult male. Duncan Multiple Range Test (DMRT) revealed that feeding activity of the species was highest and statistically significant after resting among all the behavioural activities recorded. Therefore, the species spent most of its time in feeding to fulfil their energy and nutritional requirements for survival and reproductive fitness.
