Preparation and Analysis of New Hybrid PAEK Nano-Composites Containing MWCNT, Inorganic and Organic Nano-Particles
Authors: Shripad Nirantar  
Published: May 2024

In modern era light weight material with complex shape and high material properties is required for advanced applications at room temperature. In this concern, the experimental study analysis to observe the effect of different nanofiller material like GO, MWCNT, NH2 and COOH modified MWCNT as organic nanofiller and WS2 and MoS2 as inorganic nanofiller reinforced in pure PAEK. This experimental study focuses on incorporation of organic and inorganic nanofillers separately and combine as hybrid nanofiller nanocomposite. On preparation of PAEK nano-composite and hybrid nanocomposite the comparative study of mechanical properties like tensile, flexural and impact is carried out. The nano-composites were prepared by melt compounding method. Scanning Electron Microscopy confirm the homogenous dispersion and alignment of nanofilers. The hybrid nano-composites show highest tensile strength as compared to the organic and in-organic nanofiller nanocomposite. As the percentage of MWCNT increases from 0.2 to 1 wt% , the properties of nano-composites decreases due agglomeration tendency of MWCNT that results in low load transfer capacity of nanocomposite, therefore agglomeration tendency of MWCNT required to be controlled for preparation of nano-composite and this is achieved by reinforcing Hybrid nanofillers to pure PAEK matrix. However, organic filler shows 75 MPa to 83 MPa tensile properties and which is lower compared to in-organic and hybrid filler due agglomeration tendency of organic nanofiller confirmed by SEM analysis.
Design and Development of a Hybrid Cooperative- Based Routing Protocol avoiding the void nodes in WSNs using the Concepts of Minimum Energy Consumption with good Data Security features
Authors: Manjula G. Hegde  
Published: May 2024

This paper presents a novel cooperative-based routing protocol designed for underwater Wireless Sensor Network Cloud Applications (uWSNCA). The protocol aims to minimize energy consumption by avoiding void nodes, which are areas without sensor coverage. The proposed approach consists of two main steps: first, avoiding void nodes using an adaptive hop-by-hop vector method, and second, applying a cooperative rule-based adaptive hop-by-hop vector method to create a hybrid algorithm that is more efficient than existing approaches, such as the watch-dog protocol. The research focuses on developing an energy-efficient distributed cooperative routing protocol for wireless sensor networks, specifically tailored for cooperation-based uWSNCA. This is achieved by preventing data packets from being forwarded through void nodes. The proposed routing protocol utilizes cooperation-based adaptive hop-by-hop vector-based forwarding concepts, where sensor nodes forward data packets in a multi-hop fashion within a virtual pipeline. In the developed algorithm for the underwater WSN cloud application, data packets are forwarded in a multi-hop manner using a virtual pipelining mechanism.Nodes outside the virtual pipeline do not forward data packets, thereby reducing flooding in the cooperative WSN. To prevent data packets from being forwarded towards void areas in the WSN, 2-hop information is used at each hop. This approach improves the performance of the wireless sensor network in terms of various performance criteria compared to existing routing protocols. The simulation tool NS2 is used to observe the simulation results of the energy packets being transferred from the source to the sink. The simulation results demonstrate the effectiveness of the proposed methodology. Overall, this paper contributes to the field of underwater WSNs by introducing a novel routing protocol that improves energy efficiency and performance for cloud applications.

Purpose: While organisations struggle to improve efficiency and productivity, the interaction between AI, organisational behaviour, and communication dynamics tends to be complex in the rapidly evolving modern workplace. Moreover, understanding the implications of this intersection is necessary to encourage a balanced and effective workplace. Hence, employing AI technologies in organisational structures introduces challenges such as workforce adaptation, psychological impact, and communication patterns. This research explored how AI influences organisational behaviour and communication dynamics in the modern workplace.
Study design/methodology/approach: This study used a mixed method to explore organisational behaviour and communication dynamics across diverse industries comprehensively. This questionnaire aimed to gather respondents’ experiences, focusing on organisational behaviour and communication dynamics. Furthermore, in-depth interviews were conducted with key stakeholders (n = 13) to obtain additional insights into goodness and trustworthiness. These interviews offered more depth and richness, providing insights into organisational settings. This mixed methodology ensured a complex understanding of the research problem, leveraging quantitative and qualitative data to enhance the analysis.
Findings: The research findings revealed the pathways to how AI influences organisational behaviour and communication dynamics. Initial analysis of survey data and interviews offered insights into employee perceptions, identifying potential challenges and opportunities. One major trait emerging from data analysis is employees’ unstable levels of apprehension and enthusiasm regarding AI integration. While many view it as a mechanism for efficiency, productivity, and innovation, others indicate distress about job shifts and loss of autonomy. Understanding and adopting these opposing insights are fundamental for encouraging a positive organisational ecosystem for AI readiness and adoption.
Originality/value: By examining the impact of AI on employees’ attitudes, collaboration, and communication patterns, this research contributes viable insights for organisations navigating the integration of AI into their structures.
Hydrogen Peroxide May Reduce the Risk for Revision Surgery and Infection in Primary Shoulder Arthroplasty: Two-year Follow-up From a Prospective, Blinded, Controlled Trial
Authors: Mizels Joshua , Lewis Daniel C. , Tashjian Robert Z. , Chalmers Peter N. 
Published: May 2024

Background:
The purpose of this study was to determine whether the addition of hydrogen peroxide to the preoperative skin preparation for primary total shoulder arthroplasty is associated with a difference in patient-reported outcomes, risk for postoperative infection, and risk for revision surgery at a minimum of 2-year follow-up.

Methods:
This was a prospective, blinded, and controlled trial, which included a consecutive series of patients undergoing primary shoulder arthroplasty. The control group underwent standard sterile skin preparation using ethyl alcohol and ChloraPrep applicators, and the peroxide group had the same preparation with the addition of hydrogen peroxide between the alcohol and ChloraPrep applications. We then compared patient-reported outcome scores (American Shoulder and Elbow Surgeons Shoulder Score [ASES], simple shoulder test [SST], visual analog scale [VAS]), infections, and revision surgeries between the two groups at 2-year follow-up.

Results:
Of the 61 patients included in the original study, 52 of 58 (85%) living patients agreed to participate in this study. No preoperative differences were observed between groups. No difference was observed in ASES, SST, or VAS scores at 2 years. More revision surgeries were done in the control group (7 versus 2, P = 0.268) and Cutibacterium acnes infections (2 versus 0, P = 0.168).

Conclusion:
The addition of hydrogen peroxide to the preoperative skin preparation before primary shoulder arthroplasty is safe, and additional research is warranted to investigate whether it may decrease the risk for revision surgery and postoperative C acnes infection.

Authors: Kohring Adam , Parikh Nihir , Hobbs John , Lowitz Sean , Gold Peter , Krueger Chad A. 
Published: May 2024

Introduction:
Revision total knee arthroplasty (rTKA) is a complex procedure that often requires the removal of previous implants. There is little information evaluating the difference between removing cemented or noncemented knee prostheses in revision surgeries. The purpose of this study was to determine whether removing cemented or noncemented implants would affect surgical time and expenses incurred during revision procedures.

Methods:
This retrospective cohort study used a single-institution database to identify 300 patients who underwent femoral and tibial implant rTKA from 2016 to 2022 because of mechanical complications (infection cases excluded). Radiographs and surgical reports were used to confirm whether the fixation technique was cemented (N = 243) or noncemented (N = 57). The primary outcomes were surgical time and surgery costs. Secondary outcomes included readmission rates, revision implants used, stem usage, and insurance type.

Results:
The average surgical time was 121 minutes for noncemented and 128 minutes for cemented procedures (P = 0.118). The 90-day readmission rates for each group were similar at 7.00% for the cemented cohort and 8.77% for the noncemented cohort (P = 0.643). For patients with Medicare Advantage, the respective surgery costs were $1,966 for noncemented and $1,968 for cemented TKA (P = 0.988). For patients with commercial insurance, the respective surgery costs were $4,854 for noncemented and $5,660 for cemented TKA (P = 0.330).

Conclusion:
Primary knee fixation type, cemented or noncemented, did not appear to influence the surgical duration or surgical costs of both-implant revision knee surgery indicated for mechanical complications.

A disciplina de Resistência dos Materiais é tradicional nos cursos de engenharia, e apresenta conceitos fundamentais para o entendimento do comportamento das estruturas mecânicas quando submetidas a carregamentos. Esses conteúdos são normalmente trabalhados de forma teórica. Embora os conteúdos teóricos sejam fundamentais para o entendimento de conceitos básicos durante a formação do estudante de engenharia, a utilização de atividades práticas é de grande relevância para a construção efetiva dos conhecimentos. Para uma melhor compreensão dos conceitos clássicos dessas disciplinas, pode-se realizar atividades práticas utilizando-se estruturas mecânicas instrumentadas com sensores de deformação (strain gauges) e um sistema de aquisição de dados de deformação, essa estratégia didática, proporciona ao estudante uma melhor visualização, e, consequentemente, maior abstração dos conceitos teóricos que descrevem a resposta mecânica de uma estrutura sob solicitação. Sendo assim, desenvolveu-se um sistema de aquisição de dados, para obtenção e processamento de dados relativos a sensores de deformação (strain gauges), na plataforma Arduino, e um pórtico instrumentado, com sensores de deformação (strain gauges), para a análise do comportamento de estruturas mediante diferentes carregamentos. Desta forma, obteve-se um sistema de medição e um pórtico instrumentado de baixo custo e com resultados de deformação confiáveis. Esses instrumentos foram utilizados como recursos didáticos, auxiliando no processo de ensino-aprendizagem dos conceitos na disciplina de Resistência dos Materiais.

The control of phytoematoids through the use of plant extracts with nematicide attributes represents another alternative for small producers, with affordable and economical value, besides not presenting risks of environment contamination. Due to the need to seek to increase production in an increasingly sustainable way, the objective of this study was to evaluate the effect of ‘Cunambí’ (Clibadium surinamense L.) and ‘Timbó’ (Derris elliptica) plant extracts extracted from different part of plants at different concentrations (distilled water, 2%, 4%, 6%, 8% and 10%) to control meloidogyn sp. in ‘Jambu’ (Acmella oleracea L.) under controlled conditions. The aqueous extract was obtained from crushing the plant parts used of each species. In vitro and in vivo tests were performed. The percentage of immobile nematodes was determined evaluating the nematostatic and nematicide activity of extract. In the in vitro test cunambí and timbó extracts at different concentrations showed nematicide activity on Meloidogyne sp., considering that all treatments differed from control group. When timbó extract was used, the concentration of 2% presented lower results than the other concentrations used. The application of timbó and cunambí extracts via soil did not affect height, diameter, fresh and dry shoots weight, nor even the weight of jambu root system. Despite these variations, all percentages used were able to reduce the amount of Meloidogyne sp. Therefore, timbó and cunambí extracts may be an option to control Meloidogyne sp. under controlled conditions, recommending concentrations above 4%.

El presente artículo tiene como objetivo analizar la importancia jurídica de modificar el Código Civil ecuatoriano sobre los bienes muebles con la finalidad de reconocer a los animales como sujetos de derechos, de acuerdo a la Constitución de la Republica del Ecuador de 2008. Al modificar este vacío legal permitirá que se deje de catalogar a los animales como cosas muebles y considerarlos como seres vivos envestidos de derechos que el ser humano y el Estado deben proteger. Así también esta modificación permitirá en el caso específico de las mascotas que se deje de aplicar el régimen de los bienes en la ruptura familiar por separación o divorcio y se adopte el mecanismo legal de custodia compartida o exclusiva de acuerdo al criterio del juzgador cuando este sea contencioso o mediante el acta de mediación cuando este sea de mutuo acuerdo con la finalidad de que prevalezca el derecho a la vida, integridad física y emocional de las mascotas y los derechos y obligaciones que tienes los miembros que formaron la familia. Este análisis ha sido posible gracias al Derecho comparado con la legislación española por el avance en la protección de los derechos, sirviendo de luz para este artículo.
