Mechanical Properties of FSW Joints Magnesium Alloy at Different Rotational Speeds
Magnesium (Mg) has become a focus in the transportation industry due to its potential in reducing fuel consumption and gas emissions while improving recyclability. Mg alloys are also known for their low neutron absorption, good resistant of carbon dioxide as well as thermal conductivity which makes them suitable for use in industrial equipment for nuclear energy. there has been an increasing interest in the research and development of Mg alloys. These are the lightest of all metallic structural materials and are approximately 33% lighter than aluminium (Al) and 75% lighter than ferrous (Fe) alloys and have excellent specific mechanical properties. In this work, FSW of AZ31B Alloy was examined at the various rotational speeds of 900 -1440 rpm, with fixed welding speed of 40mm/min and 2 tool tilt angle using an HSS tool. The mechanical properties were compared for the different rotational speeds. The quality of FSW joints is dependent on input value of heat and material flow rate, which are prejudiced by process parameters., higher rotation speeds may cause abnormal stirring, resulting in a tunnel defect at the weld nugget due to increased strain rate and turbulence. 2024 E3S Web of Conferences -
Rhetorics in/of English language education in India: A case of digital natives in higher education programs
The study briefly analyzes the ELT situation in India which is replete with challenges emerging from the lack of engagement with the phenomenon of digitality that further shapes the existing nature of learning and the needs of the learner. After locating the position of English Language in the new education policy of India, the paper discusses the General English (GE) courses offered at undergraduate level at the city of Bangalore in India, thereby shedding light on the existing gaps between policy and practice. It is based on this conjecture that the paper suggests the possibility of introducing rhetorical practices in GE courses at undergraduate levels in various institutions in urban India. In order to substantiate this suggestion, the results of a survey conducted with the learners (N=359) of a GE course based on rhetorics at a Southern Indian university is provided. Empirical data along with a brief reflection on the learners' voices are used in the study to examine the efficacy of the structure, administration and evaluation practices of this new course. The study thus opens up possibilities of initiating a discourse around the mode in which English language education and teaching is envisioned, formulated and implemented in undergraduate programs across urban India. 2020 ELE Publishing.

What is Remembered in Pandemic: A Commentary on the Mediated Memories of Piety in COVID-19
The paper explores how the experiences of the present pandemic are shaped by the memories of popular religious piety during past pandemics and epidemics. Taking insights from the works of Astrid Erll and Reinhart Koselleck, the process remembering-imagining system within the context of the pandemic is discussed by tracing the reemergence of pandemic deities and narratives of piety in India. Using digitally documented and disseminated narratives on piety emerging during COVID-19, an attempt is made to understand how these narratives shape the experiences, responses, and collective memory of the pandemic. Through a discussion of the shift in the imagination of political leadership and the moral responsibilities of the community, an attempt is made to highlight the mode in which the narratives on piety shape the contours of a time that is otherwise unimaginable. The mediated memories of popular religious piety make it possible to remember similar crisis times and to imagine and reinstate the social order that is threatened by this sudden unimaginable crisis. The paper thus argues that within the context of India, popular religious piety, though often overlooked, becomes a significant part of making sense and shaping the experiences of the pandemic time. 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. -
Task-based Autoethnographic Pedagogical Approach: a phenomenological inquiry into online learning of Critical Food Studies courses
The disengaging experiences reported in the online mode of learning have resulted in considerable deliberations highlighting the need for pedagogical innovations. Therefore, it is crucial to rethink these ideas and develop pedagogical approaches that accommodate a dynamic understanding of learning spaces and meet the demands of the teachinglearning environment of the contemporary period. This study discusses the various steps through which the task-based autoethnographic pedagogical approach (TAPA) was implemented in an undergraduate-level Critical Food Studies course and proposes it as an effective approach to administering certain courses by enabling active learning in the online mode. The study captures learners perceptions of meaningful online learning experiences by using an interpretative phenomenological approach, mapping the aspects that contribute to a sense of rekindled interest and involvement in the course. Some of the dominant patterns that emerge from this phenomenological study are (1) appreciation towards praxis-based online learning, (2) recognition of lived space as a ripe site for inquiry and learning, (3) a heightened sense of engagement with lived contexts, and identity discourses, (4) learners negotiations with TAPA, and (5) learner as an active agent and curator of knowledge. Thus, while situating TAPA as an effective pedagogical approach for online learning and Critical Food Studies curriculum, it is also posited as an approach that initiates negotiation with the epistemic hierarchies within academia.

Effectiveness of dialectical behavior therapy as a transdiagnostic treatment for improving cognitive functions: a systematic review
Dialectical behavior therapy (DBT) has been found to be an efficacious treatment for disorders characterized by high levels of emotional instability. In view of the multifaceted applications of DBT and the extent to which mental disorders can incapacitate cognitive functions, the current systematic review aimed to investigate the effect of DBT in strengthening cognitive functions across various mental health conditions. Original research studies employing both experimental and quasi-experimental designs were included in the review. The literature search was done using different electronic databases, from the first available literature until June 2022, that covered an approximate period of ten years. Joanna Briggs Institute checklist was used to assess the methodological rigor of the studies. Twelve studies conducted on adolescents with emotional dysregulation, and adults with borderline personality disorder, bipolar disorder, attention deficit hyperactivity disorder, and multiple sclerosis were selected. Results indicate that DBT has the potential to improve key cognitive functions such as attention, memory, fluency, response inhibition, planning, set shifting, tolerance for delayed rewards and time perception, as assessed by neuropsychological tests, self-report of cognitive functions, and neuroimaging techniques. Considering the review's findings that showcase the effectiveness of DBT in fostering improvements in cognitive functions, DBT may possibly be chosen as a preferred treatment to ensure that patients reach optimal levels of cognitive functioning. Limitations include lack of sufficient studies encompassing all the common mental health conditions, usage of neuroimaging techniques as only an indirect measure of cognitive functioning and nuances related to the quality of individual studies.

Effectiveness of internet-delivered dialectical behavior therapy skills training on executive functions among college students with borderline personality traits: a non-randomized controlled trial
Given the enormous influence of emotions on cognitive processes, individuals with borderline personality disorder (BPD) suffer from marked deficits in higher-order thinking abilities. Considering the prevalence of BPD among college students, this study aimed to investigate the changes in perceived executive functioning among college students with traits/presence of BPD undergoing internet-delivered dialectical behavior therapy skills training (DBT-ST) that included the mindfulness and emotion regulation modules. An internet-delivered version of DBT-ST was opted for, as technological advancements in the present era promote the use of online platforms for psychotherapy. This non-randomized controlled trial consisted of 36 college students with traits/presence of BPD. The intervention group attended 13 sessions of DBT-ST, and the control group attended 13 sessions of behavioral activation. Perceived executive functioning was assessed using the Behavior Rating Inventory of Executive Functions for Adults. A 2-way repeated measures analysis of variance was used to evaluate the treatment impact on the outcome variable. Results showed that the DBT-ST group had larger improvements in their abilities to initiate, plan, and organize current and future-oriented task demands and to organize their everyday environment, compared to the control group. Both, the DBT-ST group and the control group demonstrated improvements in emotional control, working memory, and their abilities to shift and task monitor. Findings suggest that the internet-delivered version of DBT-ST, consisting of the mindfulness and emotion regulation modules, can foster notable improvements in executive functions among college students with traits/presence of BPD. Improved executive functioning is one of the several multifaceted outcomes of dialectical behavior therapy. Copyright: the Author(s), 2023. -

Lanthanum oxide nanoparticle (La2O3 NPs) were synthesized by co-precipitation technique using Plectranthus amboinicus (P. amboinicus ) leaf extract. A yellowish green color was observed after the addition of leaf extract to the NaOH solution. The synthesis of nanoparticles plays a vital role in the field of science and technology. The cubic structure of the La2O3 was confirmed by Powder XRD. The functional groups present in the NPs were confirmed by FT-IR spectroscopy. The absorbance spectrum was observed at 274nm in the wavelength range of 230850nm. The calculated band gap value was 4.32eV. The structural morphology of La2O3 NPs was observed as cubic and irregular shape obtained from SEM image and EDAX spectrum which confirms the presence of La and O elements. The average particle sizes of the NPs were observed to be 40.22nm analyzed by high resolution transmission electron microscopy (HR-TEM) analysis. The main objective of this research work was focused on prepared La2O3 NPs act as a potential inhibitor to handle various inflammations and diabetes problems. Bovine serum albumin (BSA) denaturation approach produced a strong anti-inflammatory response with 92.89% inhibition at 500g/mL while ?-amylase showed significant antidiabetic activity of about 94.55% inhibition at 500g/mL. These results suggest that the green synthesized nanoparticles can be used for ?-amylase and BSA denaturation inhibitory activities, which may be crucial for biomedical applications.

Intention to Stay in Relation to Organisational Socialisation Processes
Attrition is significant in an organisation as replacing human capital bears a significant cost. This study focuses on the effect of organisational socialisation processes, followed in Indian and Multinational BPO organisations on an employees intention to stay within that organisation. A field research with 395 samples was steered using a standardised 21 item questionnaire, to capture the four constructs of Organisational Socialisation and Intention to stay. Results show that there a significant relationship is prevalent between Intention to Stay and Organisational Socialisation in BPOs. Also, amongst the dimensions of organisational socialisation, future prospects and understanding of the role were associated significantly with intention to stay. It is acknowledged that higher organisational socialisation leads to greater intention to stay among employees. The critical purpose in employee retention includes keeping the organisation relevant to the employees by carefully creating their career development plans, helping them manage their work-life balance, and providing timely recognition of talent and then rewarding them. This is imperative to the HR Management as a remedy to soaring attrition rates which is also due to Future prospects and Understanding of the role, as per the findings.
