In present study, twenty different wheat varieties were evaluated for various agronomic traits including plant height, number of tellers per plant, leaf area index, spike length, number of spikelets per spike, number of grains per spike, peduncle length, chlorophyll index, thousand-grain weight, grain yield, and biological yield at the research area of Agronomy, Hafiz Abad Research Station, College of Agriculture B.Z.U. Bahadur Campus Layyah during crop season 2020-2021 and 2021-2022. The study was designed following RCBD (Randomized Complete Block Design) with 3 replications of each treatment. Each plot in the study was 4 meters in length and 5 meters in width. The wheat genotypes that were evaluated exhibited significant variability for all of the attributes under investigation. Grain yield was significantly correlated with the spike length, number of spikelets per spike, plant height, 1000-grain weight, number of grains per spike and flag leaf area. Multivariate analysis showed that 20 different wheat varieties formed 3 different clusters. Cluster-1 showed maximum mean values for yield and yield-related attributes compared with cluster-2 and cluster-3. The genotypes accounted for 95% of the total variation in grain yield and associated characteristics, accounting for a significant proportion of the overall differences. In general, the results of this study showed that genotypes like FSD-08, Ujala-16, Fakhr-e-Bhakhar-19, and Akbar-19 have the highest yield potential when grown in the semi-arid climate of Layyah, Pakistan. Thus, all these genotypes were suggested for general cultivation in arid conditions of district Layyah.

Authors: Chen Zhaohua , Lu Zhenhua , Wu Zhipeng
Published: February 2024

A new hybrid containing alkali metal-organic framework and polymeric iodoargentate, {[K(bpdo)2](AgI2)}n (1) (bpdo = 4,4'-dipyrdiyl-N,N'-dioxide) has been synthesized by solution process and structurally determined, which is the first potassium-based 3-D network constructed from linear bpdo ligands and also serves as host for accommodating 1-D polymeric (AgI2)nn− chains. The 3-D [K(bpdo)2]nn+ metal-organic framework can be described as the result of bridged [K(bpdo)2]nn+ 2-D sheets by KO8 square antiprisms, in which electrostatic interaction among bpdo ligands solidifies this network. The straight-linear (AgI2)nn− is constructed from edge-sharing of AgI4 tetrahedra, which is accommodated in the channels of 3-D [K(bpdo)2]nn+ network. This hybrid is a semi-conductor with optical gap of 2.80 eV. Besides, 1 exhibits effective and repeatable photocurrent responses with current density of 1.40×10− 7 A, and the photocurrent response mechanism was also discussed.

Published: February 2024

Background：The prevention of myopia in adolescents has become a focus of public health in the world, and the important role of eye health behaviors in the prevention and control of myopia in children and adolescents is further clarified by analyzing the risk factors related to myopia.Methods:From September to November 2021, a total of 16,464 primary and secondary school students aged 6 to 18 in Baotou City were selected for vision screening, refractive check, and a questionnaire survey of myopia-related factors using stratified cluster sampling.Results：Among the primary and secondary school students, the myopia rate was 56.1%, the hyperopia rate was 11.0%, the astigmatism rate was 39.5%, and the rate of high myopia was 6.3%. The myopia rate was higher in urban areas (57.12%) than in suburban areas (55.17%) and higher in girls (59.52%) than in boys (52.81%). Multifactorial logistic regression analysis showed that risk factors for myopia included being male, having high BMI, having one or both parents with myopia, spending more than one-hour doing homework at home, doing close work for more than one hour, and frequent or always reading while lying down. Doing eye exercises once a day or more and sleeping more than eight hours were protective factors for myopia.Conclusions:The prevalence of myopia among primary and secondary school students in Baotou City is high, and myopia is affected by a combination of factors such as education stage, genetics, eye habits, and eye environment, so effective interventions should be taken to prevent myopia in children and adolescents.
Optimizing Merger Targets in the Banking Industry: A Stochastic Approach using Inverse Data Envelopment Analysis and Goal Programming
Authors: Hadi-Vencheh A. , Khodadadipour M. , Tan Y. , Arman H. , Ghasemi Peiman
Published: February 2024

This paper presents a new approach to address target setting in mergers by utilizing two complementary techniques: Goal Programming (GP) and Inverse Data Envelopment Analysis (InvDEA). Traditional DEA models assess the relative efficiency of decision-making units (DMUs) based on multiple inputs and outputs. However, InvDEA focuses on determining the input and output quantities required to achieve a specific efficiency score target. These models face limitations when deviations from the frontier occur due to noise and random errors in the data. To overcome this issue, this paper introduces a novel stochastic method that estimates the input/output levels of the merged unit needed to attain the predetermined efficiency score at a specified level of significance (α ∈ [0, 1]). Our models proposed are applied to the banking industry, demonstrating their effectiveness. The study provides decision makers with a valuable method to incorporate their preferences when setting merger targets, enabling them to optimize savings in specific inputs or maximize the production of desired outputs. To validate the proposed method, an illustrative application is conducted within the banking industry.

Published: February 2024

This paper reviews the utilization of Gold Ore Tailings (GOTs) in manufacture of Geopolymer Concrete (GPC) along with Recycled Coarse Aggregates (RCAs). The paper also highlights the workability and mechanical properties of GPC. The results of the study demonstrated that the slump value of GPC samples was 35.1 mm for 15% replacement of GOTs to River Sand (RS) which was lower than that of Conventional Concrete (CC2) samples (i.e., 110 mm). The compressive strength, split tensile strength, and flexural strength of GPC samples were 47.8 MPa, 5.01 MPa and 6.98 MPa, respectively and these results were better when compared to CC2samples (i.e., compressive strength of 47.4 MPa, split tensile strength of 4.4 MPa and flexural strength of 4.89 MPa). The statistical analysis was conducted to predict the experimental results in which R2 values of developed model for compressive strength, split tensile strength, and flexural strength was 70%, 85.5%, and 89%, respectively. The Field Emission Scanning Electron Microscopy (FESEM) analysis of GPC samples observed development of rod-like ettringite, which makes the GPC paste more compact and denser. Finally, the cost analysis was done to know the economic feasibility of optimum mix of raw materials utilized for the manufacture of GPC and CC2. It was found that the cost of GPC was 38.20% more than that of CC2.

Authors: Truong Van Thuy , Yates James , Vicini Paolo , Dubois Vincent , Lythe Grant
Published: February 2024

We have developed a three dimensional hybrid multi-scale agent-based ODE PDE model including tumour immune interaction, cell cycle phases, oxygen and drug diffusion dynamics, the pharmacodynamics of chemotherapy, targeted therapies, immunotherapy, radiotherapy and the respective systemic exposure levels of pharmacological treatments (described by pharmacokinetic modelling). The aim of this model is to support a more detailed understanding of the spatial-temporal dynamic interactions between cancer cells, the relevant immune cells, and especially targeted therapies' molecular moieties, which are all expected to interact simultaneously in the tumour microenvironment. This interaction can then be further investigated in the context of combination therapies, thus making some inroads in the mechanistic understanding of positive and negative synergies when multiple therapies are administered within this complex system. The key scientific question this work addresses is the role of temporal sequencing in combination therapies, which require the simultaneous modelling of many relevant components of the system to be properly understood.
A second-order scheme with nonuniform time grids for the two dimensional time-fractional Zakharov-Kuznetsov equation
Authors: Chen Lisha , Wang Zhibo
Published: February 2024

In this paper, we investigate the numerical method for the two dimensional time-fractional Zakharov-Kuznetsov equation. By the method of order reduction, the model is first transformed to an equivalent system. A nonlinear difference scheme is then proposed to solve the equivalent model, with min{2, rα}-th order accuracy in time and second-order accuracy in space, where α ∈ (0, 1) is the fractional order and the grading parameter r ≥ 1. The existence of the numerical solution is carefully studied by the renowned Browder fixed point theorem. With the aid of Grönwall inequality and some crucial skills, we analyze the unconditional stability and convergence of the proposed scheme based on the energy method. Finally, numerical experiments are given to illustrate the correctness of our theoretical analysis.

Published: February 2024

The objective was to identify the best stocking density in the initial fattening phase of tambaqui (Colossoma macropomum) using biofloc technology (BFT) and evaluate the effects of the densities on water quality, zootechnical performance and the metabolic profile of fish and production costs. Juveniles (56.5 ± 1.69 g) were reared in the densities: 15 (BFT15), 30 (BFT30) and 45 (BFT45) fish.m− 3, in triplicate, for 80 days. The use of BFT inoculum at the beginning contributed the maintenance of adequate ammonia and nitrite concentrations at all densities, though with a higher nitrite concentration in BFT45. Electrical conductivity (EC), nitrite, total suspended solids (TSS), pH, alkalinity and hardness were different (p < 0.05) between BFT15 and BFT45. EC and TSS increased according to the increase in density, and were higher in BFT45. The highest final weight, weight gain, daily weight gain and specific growth rate were observed in BFT15, while the apparent feed conversion was lower for BFT15 and BFT30 compared to BFT45 (p < 0.05). Biomass and productivity were higher (p < 0.05) in BFT45. The values of hematocrit, number of erythrocytes and the hemoglobin concentration were higher in BFT45 (p < 0.05). Regarding production costs, the highest average feed expenditure occurred in BFT45; however, expenditure with electricity was lower at this density. The increase in biomass in BFT45 generated the reduction of the partial average cost (ACp). It can therefore be concluded that the best stocking density for initial fattening of tambaqui is 45 fish.m− 3, since it presents better productivity and biomass, lower ACp and average expenditure on electricity when using BFT.
SACNet: Switchable Atrous Convolution Network Based on Diffusion Model for Small Object Detection from UAV Images
Authors: Wang Xiao , Zhu Haijiang , Li Zhiqing
Published: February 2024

Small object detection has always been one of the most challenging tasks in the computer vision. Up to now, a prior bounding box is often applied to Unmanned Aerial Vehicle (UAV) image object detection. However, anchors need to be pre-set and not optimal for training data in many object detection algorithms. In 2022, the Diffusion Model was introduced in object detection method, in which the random boxes are employed. Inspired by this method, we propose a Switchable Atrous Convolution Network based on the Diffusion Model. First of all, the normalized Wasserstein distance (NWD) is led into measuring the similarity between the prediction box and the ground truth box. The purpose is to eliminate the influence of positional sensitivity on the matching between the predicted box and the ground truth box. Secondly, a Switchable Atrous Convolution (SAC) with different atrous rates and shared weights is introduced, and similar features at different scales are extracted. This can solve the challenge of significant scale variations of the same target in the image. Finally, Pixel shuffle and Upsampling operations are employed in the feature extraction backbone network to enhance the model's ability to detect small targets. The optimal results of 27.89% mAP on the VisDrone dataset and 8.42% mAP on the Tinyperson dataset demonstrate the effectiveness of the proposed model.

Chewing khat (Catha edulis) releases cathine and cathinone, which may reduce appetite through an unknown mechanism. This study investigated the peripheral and central effects of fresh leaves and buds of C. edulis water extract (CEWE) on appetite and body weight, using in vivo, ex vivo, and in silico models. Rats of both sexes were used for three different experiments. Serotonin receptors were studied using isolated rat fundus samples and molecular docking. Significant differences in body weight were observed in the CEWE-treated groups compared with the controls over eight weeks. However, plasma leptin and ghrelin levels did not change significantly. The expression of the ghrelin and leptin genes was also unaffected, but the expression of the 5-HT gene decreased with CEWE treatment. CEWE antagonizes 5-HT receptors in isolated rat fundus samples. In silico docking indicated that the khat ligands inhibited 5-HT2C receptors. Cathine and cathinone levels in rat plasma were measured. These findings suggest that the appetite-suppressing role of khat can be attributed to its antagonistic effect on 5-HT receptors. Further research is needed to fully understand the mechanism of action of the khat extract. These findings provide a basis for future studies to validate and expand on these discoveries.
DFT Investigation for the Mechanisms of γ-Butyrolactones from Styrene and Acrylic Acid, Catalyzed by NMA*BF 4 and PhSSPh
Authors: Yang Bing , Zhou Da-Gang
Published: February 2024

The reaction mechanisms of γ-butyrolactones through electrophilic addition reactions between styrene and acrylic acid, catalyzed by the 9-mesityl-10-methylacridinium ion (NMA*BF4) and diphenyl disulfide (PhSSPh) under 450 nm visible-light, were investigated by employing M06-2X-D3/ma-def2SVP method and basis set. In this study, the SMD model was taken to simulate the solvent effect of dichloromethane. The photocatalyst NMA absorbs the energy of photons and becomes an excited state, capturing an electron from styrene; This leads to an electrophilic addition reaction happened between the obtained styrene cationic radical and acrylic acid anion (or acrylic acid molecule); finally, an intramolecular ring-closure process and H-shift process result in the formation of the final product. The computational results point out that the electrophilic reaction is an exothermic process; and the optimal path for ring-closure reaction and H-shift reaction has Gibbs free energy barriers of 11.10 and 9.94 kcal/mol, respectively In particular, the recycling of the photo-catalyst NMA and cocatalyst PhSSPh has also been discussed. The ρhole and ρele can reveal the charge transfer process during the photo-catalytic reaction. Results would provide valuable insights into these types of interaction and related processes.
Protein Function Prediction Through Multi-view Multi-label Latent Tensor Reconstruction
Authors: Armah-Sekum Robert Ebo , Szedmak Sandor , Rousu Juho
Published: February 2024

Background:: While the advent of high-throughput sequencing technologies has accelerated the pace of discovery of proteins, the functions of the majority of them remain unknown. This is mainly due to the time and resource limitations of rigorous experimental functional characterization, which is carried out for only a few select organisms. Consequently, computational methods providing relatively fast and accurate information about the potential cellular activities of a protein are sought after. However, the prediction accuracies of current tools, as assessed through the Critical Assessment of Functional Annotation (CAFA) competition, generally still falls short of the desired level.
Results:: We present GO-LTR, a multi-view multi-label prediction model that relies on a high-order tensor approximation of model weights combined with non-linear activation functions. The model is capable of learning high-order relationships between multiple input views representing the proteins and predicting high-dimensional multi-label output consisting of protein functional categories. We demonstrate the competitiveness of our method on various performance measures. Experiments show that GO-LTR learns polynomial combinations between different protein features, resulting in improved performance. Additional investigations establish that GO-LTR shows a high potential in predicting highly specific terms in the gene ontology.
Implementation:: The code and data used for training GO-LTR is available at https://github.com/aalto-ics-kepaco/GO-LTR-prediction
WITHDRAWN: Water Distribution Network Design Using waterGems
Authors: Yennawar Rushikesh Rameshrao
Published: February 2024

The water distribution network (WDN) of the Nanded City was designed in 1974 for a population of 4 lakh people. It was extended twice in 1986 and 2001. Due to the extended portion and increased population, required pressure and discharge are not available, especially at the tail end of the network. Hence the capacity expansion analysis, revisit to the design and operation of the WDN is necessary to analyze for required pressure and discharge parameters. The main objective of this study is to analyze the WDN for existing pipe diameters and to design for modified diameters satisfying given hydraulic constraints. This work presents the analysis and modified design of the WDN of Taroda which is part of the Nanded City. The model representing 1737 pipes and 1306 nodes is prepared in WaterGEMS and the tool Darwin Designer from WaterGEMS is used for designing the WDN that solves all nodes and gives the pressure head and flow in the network. After analysis, the WDN is designed for revision in design defining an objective function to maximize hydraulic benefits satisfying all given constraints. The design results give satisfactory results for the optimization of pipe diameters. The pressure at each node was found positive except for only 7 nodes at the extreme ends of the network. This design used available diameters of pipe given as an input and excludes diameters 150mm, 200mm, and 300mm as per given requirements for given constraints.
Polaron spectroscopy of interacting Fermi systems: Insights from exact diagonalization
Authors: Amelio Ivan , Goldman Nathan
Published: February 2024

Immersing a mobile impurity into a many-body quantum system represents a theoretically intriguing and experimentally effective way of probing its properties. In this work, we study the polaron spectral function in various environments, within the framework of Fermi-Hubbard models. Inspired by possible realizations in cold atoms and semiconductor heterostructures, we consider different configurations for the background Fermi gas, including charge density waves, multiple Fermi seas and pair superfluids. While our calculations are performed using an exact-diagonalization approach, hence limiting our analysis to systems of few interacting Fermi particles, we identify robust spectral features supported by theoretical results. Our work provides a benchmark for computations based on mean-field approaches and reveal surprising features of polaron spectra, inspiring new theoretical investigations.
The Virasoro minimal string
Authors: Collier Scott , Eberhardt Lorenz , Mühlmann Beatrix , Rodriguez Victor A.
Published: February 2024

We introduce a critical string theory in two dimensions and demonstrate that this theory, viewed as two-dimensional quantum gravity on the worldsheet, is equivalent to a double-scaled matrix integral. The worldsheet theory consists of Liouville CFT with central charge c≥≥ 25 coupled to timelike Liouville CFT with central charge 26-c. The double-scaled matrix integral has as its leading density of states the universal Cardy density of primaries in a two-dimensional CFT, thus motivating the name Virasoro minimal string. The duality holds for any value of the continuous parameter cc and reduces to the JT gravity/matrix integral duality in the large central charge limit. It thus provides a precise stringy realization of JT gravity. The main observables of the Virasoro minimal string are quantum analogues of the Weil-Petersson volumes, which are computed as absolutely convergent integrals of worldsheet CFT correlators over the moduli space of Riemann surfaces. By exploiting a relation of the Virasoro minimal string to three-dimensional gravity and intersection theory on the moduli space of Riemann surfaces, we are able to give a direct derivation of the duality. We provide many checks, such as explicit numerical - and in special cases, analytic - integration of string diagrams, the identification of the CFT boundary conditions with asymptotic boundaries of the two-dimensional spacetime, and the matching between the leading non-perturbative corrections of the worldsheet theory and the matrix integral. As a byproduct, we discover natural conformal boundary conditions for timelike Liouville CFT.

Hands and Hand-Related Motifs in Creative Visual Advertising
The author summarizes typical ways of using the motif of hands in advertising, then focuses on examples of creative advertising, i.e. a form of marketing that, as a rule, aims to attract attention by breaking the presentation schemes, surprising, and often also shocking the recipient. The following types of advertisements can be distinguished within this category: (1) advertisements based on transsemiotic delexicalization of phrases or expressions related to hands or activities performed with them; (2) advertisements ascribing to hands some extraordinary features or properties that conflict with common knowledge about the world and as such require a non-literal interpretation; (3) advertisements relying on the animalization or reification of hands; (4) advertisements featuring hand/palm/finger themes in unusual, drastic, or obscene situational contexts; (5) advertisements in which motifs related to hands are an element of intertextual play of meanings.
Avaliação da Educação Superior

Published: February 2024

Com o objetivo de alcançar a qualidade no ensino superior, o governo brasileiro implantou o Sistema Nacional de Avaliação da Educação Superior (SINAES), que qualifica cursos de graduação de maneira conservadora. Paralelamente, muitas universidades se caracterizam pela adoção da visão da complexidade como base para a transformação educacional. Nesse contexto, o objetivo deste artigo é analisar os impactos da avaliação promovida pelo SINAES em cursos de graduação cujas experiências educacionais estão vinculadas a movimentos pedagógicos transformadores. A pesquisa, que utilizou métodos de análise documental e histórica e teve sua base conceitual no paradigma da complexidade de Edgar Morin, revelou que o SINAES não considera abordagens inovadoras alinhadas com as necessidades atuais e que experiências como a do curso de Arquitetura obtiveram resultados positivos. Conclui-se, portanto, a importância de repensar os sistemas de avaliação, incorporando a teoria da complexidade, para uma visão mais abrangente da educação superior.

Development of an immunological technique for detecting granulovirus infection in Tuta absoluta larvae (Lepidoptera: Gelechiidae)
Authors: Herrera C. Lorena , Villamizar R. Laura , Gómez V. Juliana
Published: February 2024

Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), known as tomato moth or tomato leafminer is a microlepidopter from Gelechiidae’s family, which is widely distributed on America, Europe, Africa and Asia and is considered the most important pest of this crop (Roditakis et al. 2010). Phthorimaea operculella granulovirus (PhopGV) has been used for controlling larvae of different moths from Gelechiidae’s family as Tecia solanivora and P. operculella in several countries of South America as Colombia, Brazil, Argentina and Peru, and probably can also be pathogenic for T. absoluta larvae. However, viral isolates from this insect has not been reported nowadays, possibly due to the small larvae size and the difficulty for detecting the virus. In this sense, the aim of the present work was to develop an economic, fast and accurate immunological technique for granulovirus detection in T. absoluta larvae
Strategi Mengatasi Aksesibilitas Destinasi Pulau Kecil Dengan Penyesuaian Segmentasi Wisatawan Kepulauan Riau

Published: February 2024

A prevalent challenge encountered by small islands pertains to accessibility. Nevertheless, numerous ostensibly isolated islands attract a substantial number of tourists. This article examines the relationship between accessibility and tourism development on small islands to understand the two better. Qualitative data collection methods were utilized for this study, including in-depth interviews, the collection of pertinent secondary data, and field observations. Following analysis, the collected data were presented in a comparative descriptive fashion. A discussion of the island approach (islands and archipelagos) is undertaken to comprehend the interconnections between minor islands and other locations within the larger region. Field research indicates that despite possessing the aesthetic appeal of beaches and sea, many small islands still need to exploit their tourism potential fully. This is primarily due to the exorbitant transportation expenses for domestic visitors and the need for adequate tourism infrastructure, including resorts and hotels of international caliber catering to affluent-class tourists (middle and above). Conversely, despite being classified as remote islands, the Riau Archipelago maintains strong diplomatic relations with neighboring nations. It can attract international visitors for cultural tourism, beach activities, and scuba diving. Small islands may benefit from a strategy targeting affluent classes and foreign tourists. In order to develop the tourist experience on small islands by expectations, it is necessary to enhance tourism infrastructure and services for tourists and tourism investors as a result of targeting the tourist segment.
Strategi Pengelolaan Sektor Pariwisata oleh Pokdarwis Desa Wisata Srikeminut pada Masa Krisis Pandemi COVID-19
Authors: Dewi Vivian Noor Safira
Published: February 2024

Srikeminut Tourist Village is among the tourist communities adversely affected by the COVID-19 pandemic. Pokdarwis is among the entities tasked with managing the tourism industry during the pandemic. By applying the theory of tourism disaster crisis management offered by Ritchie (2004), this research endeavors to ascertain the approach adopted by the Pokdarwis of Srikeminut Tourism Village in handling the tourism industry amidst the Covid-19 pandemic crisis that transpired between 2020 and 2022. Therefore, this research focuses on two primary topics: firstly, the categorization of the Pokdarwis strategy about the stages of crisis management, and secondly, the identification of the Pokdarwis strategy in the recovery of the tourism sector. The findings indicated that Pokdarwis resorted to a sequence of strategic implementations in light of the pandemic rather than engaging in preventative measures and strategic planning. Implementing health protocols, creating virtual events, limiting the number of visits, collaborating with internal and external parties, suspending several tourist activities, and promoting tourist attractions via Instagram are all methods to achieve this objective. Pokdarwis' approach to tourism sector management has facilitated the gradual recovery of Srikeminut Tourist Village from the pandemic crisis. By 2022, it will be possible to classify the Srikeminut Tourist Village as having reached a stage in its crisis anatomy known as the long term (recovery), wherein all forms of tourism activities can be resumed as before, and the village community will have acclimated to the new normalcy. To attain this position, Pokdarwis engaged in a succession of partnerships with internal and external entities, implemented a crisis communication strategy, and provided tourism managers and Pokdarwis personnel with a variety of training on sector management.
Freudian Trivialization of the Characters’ Problematic and Traumatic Death Drive in After Death and Aurora Leigh
Authors: Luo Jun
Published: February 2024

With respect to the Freudian psychanalytical meditation on the complicated minds of the vivid characters depicted in the introspective and instructive production of Christina Rossetti’s After Death (1866), and, Elizabeth Barrett Browning’s Aurora Leigh (1856), it has come to the minds of an increasing number of experienced readers that it takes them to think much more of the crucial connection of the theoretical insights carried in Freudian death drive and the particular development of the perceptive and cognitive potentialities of the characters depicted in the symbolic and strategic characterization of those two poems produced for the evident, authentic, and, essential revelation of their unconscious minds as mirrored in the insightful and ingenuous trivialization of the problematic and traumatic thoughts and actions of the characters of those two poetic texts to be read in line with what has been manifested in the reliable visualization and narrativization quite conducive for the euphemistic purification and pacification of the peaceful and painful minds instilled into the interweavement of the crucial narrative facts and narrative events valuable for the representation of the mindsets of those who have been symbolized in the poeticization of the social thoughts and actions of those who have lived and worked in Victorian age. However, what seems to be quite pitiful in the critical and crucial valuation, evaluation, and revaluation of the rather high perceptive and cognitive compatibility epitomized in the essential and evident elaboration of the unvisited perceptive and cognitive microcosm of those characters, is, that the critical attention of most literary scholars has seldom been paid to the intentional trivialization of the true physical and spiritual mishaps those characters have suffered from in their lives and experiences. To have a much better understanding of their strong intrinsic perceptive and cognitive inclination, this essay will make an exploration of the characters’ similar death drive trivialized in the euphemistic figuration, configuration, and, transfiguration of their problematic and traumatic misfortunes of those miserable characters indebted to the theoretical enlightenment acquirable from the aggression, repetition, compulsion, and, self-destructiveness in the elaboration of Freudian death drive.
Cultural Crossroads and Subaltern Realities in Diasporic Discourse: Exploring the Sense of Belonging in Lahiri and Mistry’s Narratives
Authors: Akhtar Aamina
Published: February 2024

This study examines the theme of cultural navigation and the sense of belonging in Jhumpa Lahiri's novel The Namesake and Rohinton Mistry's A Fine Balance. Focusing on the Indian diaspora, the study meticulously explores the multifaceted dimensions of subalternity embedded in the characters' experiences of cultural displacement, identity negotiation, and socio-economic adversities. This research paper aims to elucidate the complex dynamics of belonging in a diverse and interconnected global community by conducting a comparative analysis of the many ways in which these narratives portray the journeys of people bridging many cultures. In navigating the complex fabric of two separate cultures, this paper explores the challenges, triumphs, and transformations of the protagonists. It investigates the literary techniques employed by Lahiri and Mistry to portray the psychological and emotional aspects of cultural adaptation, illuminating the characters' changing self-perceptions. It also examines how society and family dynamics shape the identities of the characters, highlighting the conflict between the desire for integration and clinging to one's traditional origins. Through a thematic analysis, this study seeks to uncover the authors' perspectives on cultural hybridity, shedding light on the broader implications for individuals striving to reconcile their heritage with the demands of contemporary life. The study also looks at how the characters' sense of place affects their sense of belonging, examining how the writers employ location as a narrative device to highlight the contrasts between cultures. This comparative approach aims to provide various insights into the ways in which Lahiri and Mistry articulate the multifaceted nature of cultural identity and how it changes over time and contributes to a deeper understanding of the intricate interplay between culture, identity, and belonging in contemporary literature.

However, few studies on parasites of this rodent are available throughout its geographic distribution. The aim of this study was to explore, describe and compare the structure of helminth communities from 2 populations of L. maximus in semi-captive (SCHP) and wild (WHP) conditions in Buenos Aires Province, Argentina. The structure of helminth communities was studied considering ecological data at different levels. Seven helminth taxa were collected. Graphidioides spp. and Lagostonema ecasiense were the most prevalent species in SCHP, and Viannella viscaciae in WHP. This last species showed the highest values of mean intensity and mean abundance in both host populations. Helminths from SCHP showed higher values of abundance, mean intensity, mean abundance, diversity, and evenness, and lower values of specific richness and dominance than WHP. Specific richness, evenness and dominance allowed separating the 2 host populations. The abundances of V. viscaciae and Graphidioides spp. distinguished both host populations, suggesting possible influences of human intervention and/or environmental characteristics, as consequence of semi-captive and wild conditions.

Abstract: This paper presents the design and development of a sophisticated military security drone equipped with advanced components including Pixhawk flight controller, GPS module, camera, receiver, telemetry system, BLDC (Brushless Direct Current) motors, and electronic speed controller (ESC). The Pixhawk flight controller serves as the brain of the drone, managing flight dynamics, navigation, and mission planning with remarkable precision and reliability. Integrated with a highaccuracy GPS module, the drone achieves autonomous navigation capabilities, enabling it to execute pre-defined flight paths and perform missions with minimal human intervention. A high-resolution camera system is incorporated into the drone, providing real-time video surveillance and reconnaissance capabilities. This camera system is complemented by a receiver module, facilitating remote control and data transmission between the drone and ground control station.Furthermore, the telemetry system enables remote monitoring of the drone's vital parameters, including altitude, speed, battery status, and sensor readings. This real-time telemetry data enhances situational awareness and facilitates informed decision-making during missions.The propulsion system of the drone consists of BLDC motors and electronic speed controllers, offering efficient and reliable propulsion for sustained flight operations. These components are carefully integrated to optimize power consumption, flight endurance, and maneuverability, ensuring the drone's effectiveness in various operational scenarios. In summary, the integration of Pixhawk flight controller, GPS module, camera, receiver, telemetry, BLDC motors, and electronic speed controller in the design of the military security drone represents a significant advancement in unmanned aerial technology. The resulting drone platform offers enhanced capabilities for surveillance, reconnaissance, and security applications, contributing to the effectiveness and efficiency of military operations in diverse environments

The Eastern Tropical Pacific (ETP) is characterized by complex oceanographic dynamics that affect the regional sea surface temperature (SST), a key parameter driving marine ecosystems. To date no comparative studies have been conducted on the spatial and temporal variations of SST among the several marine protected areas in the ETP. The present study used remote sensing to evaluate the monthly, annual, and decadal variations in SST from 1982 to 2019 in Coiba National Park (Coiba), Cocos Island National Park (Cocos), Malpelo Fauna and Flora Sanctuary (Malpelo), Gorgona Island National Park (Gorgona), Galápagos Marine Reserve (Galápagos) and La Plata Island (La Plata). An overall increasing trend in SST was observed across all study sites, except for West Galápagos. A decrease in SST anomaly was observed from February through April at Malpelo, Coiba, Gorgona and La Plata. These observations are likely in response to the Humboldt Current and upwelling events in the Colombian Pacific Basin. Using a longer SST dataset is recommended to determine if the annual, monthly and decadal trends observed here are driven by local, regional or global processes. Consistent monitoring of SST trends is a strategic practice in understanding and planning for current and projected changes in the marine environment.

Long-term trends of length and mean age at sexual maturity (MLSM and MASM) of female Patagonian hoki Macruronus magellanicus (2001 to 2019) and southern hake Merluccius australis (1989 to 2019) were analyzed in overexploited stocks from the Outer Sea (OS) and Inner Sea (IS) of Chilean Patagonia. The study of the samples was performed by microscopic analysis of the gonads and part of them were analyzed histologically, together with fish otoliths readings. MLSM and MASM were calculated using a generalized linear model. MLSM of hoki in the OS experienced large annual fluctuations, with a difference of 16.2 cm between extreme values. MLSM was 55.3 cm in 2001 and 44.1 cm in 2019. MASM ranged between 2.9 and 4.4 years. In the IS (only one year sampled) precocious maturation was found in females between 32 cm and 35 cm total length (TL). MLSM of southern hake was rather stable within a range of 5.5 cm, from 73.5 cm TL in 1989 to 73.9 cm in 2019. MASM ranged between 10.4 and 11.6 years. MLSM in the IS was 4.5 cm TL lower than in the OS in the three years of sampling. Life history information of these species suggests that favorable environmental conditions in the IS allow them to reach MLSM earlier than in the OS.
Alimentación del bonito Sarda chiliensis (Pisces: Scombridae) en el norte de Chile
Authors: Medina Marianela , Araya Miguel
Published: February 2024

The diet of Sarda chiliensis from artisanal fishing in northern Chile from May 2017 to March 2018 was analyzed. Stomach content analysis resulted that the most frequent and abundant prey was Pleuroncodes monodon with the highest value of Index of Relative Importance in the diet (%IRI= 45.8) followed by Engraulis ringens. No correlation was found between the length of the main prey (P. monodon and E. ringens) and the size of the predator. S. chiliensis tended to be a generalist predator (Bi= 0.75) with a trophic position NT= 4.3, a trophic level characteristic of species considered top predators.
Por una ética posthumana: Aportes desde Braidotti, Sloterdijk y Marchesini
Authors: Piedra-Alegría Jonathan
Published: February 2024

Este ensayo filosófico, que se enmarca en el paradigma cualitativo y documental, se realiza una exploración del concepto de posthumanismo, guiado por las contribuciones de tres pensadores prominentes: Rosi Braidotti, Peter Sloterdijk y Roberto Marchesini. Utilizando la hermenéutica como metodología interpretativa, el ensayo aborda los textos escritos de estos autores para desentrañar y comprender sus ideas. El posthumanismo, como marco filosófico, desafía las fronteras del humanismo clásico, replanteando la posición del ser humano en relación con la naturaleza y la tecnología junto con otras entidades significativas. En este contexto, las conexiones e interacciones con el ambiente, los sistemas tecnológicos, así como otros seres vivos se vuelven fundamentales en la construcción de la identidad y la experiencia humana. A través de un análisis de las obras de Braidotti, Sloterdijk y Marchesini, el ensayo revela cómo el posthumanismo actúa como una crítica incisiva del antropocentrismo, al igual que de los humanismos tradicionales, ofreciendo una perspectiva renovada y crítica sobre la ética y la condición humana en nuestra era contemporánea.
