Evaluation of diesel engine performance and emissions using biodiesel from waste oils synthesized with FeO-SiO heterogeneous nano catalyst.

Purpose: Biodiesel is a non-toxic, renewable, and environmentally friendly fuel used in compression ignition engines. This work aimed to develop FeO/SiO as a cheap, magnetic, and easy separable catalyst for biodiesel production from waste oil by sono-catalytic transesterification.

Methods: Fe₃O₄-SiO₂ was prepared using a modified Stober method and used as a heterogeneous catalyst in an ultrasound-assisted transesterification reaction to produce biodiesel.

Enhancing growth, yield, essential oil content, and composition of holy basil (Ocimum tenuiflorum L.) using red algae-based bio-stimulant under acidic conditions of the Western Himalayas.

Background: The rising costs of synthetic fertilizers highlight the need for eco-friendly alternatives to enhance essential oil production in aromatic plants. This study evaluated the effects of red algae seaweed extract [Solieria chordalis (C. Agardh) J.

A two-tier optimization strategy for feature selection in robust adversarial attack mitigation on internet of things network security.

Adversarial attacks were commonly considered in computer vision (CV), but their effect on network security apps rests in the field of open investigation. As IoT, AI, and 5G endure to unite and understand the potential of Industry 4.0, security events and incidents on IoT systems have been enlarged.

The Role of Sustainable Social Work in Pro-Environmental Behaviors: A Mediation and Moderation Model.

Purpose: This study seeks to investigate the effectiveness of psychological interventions in promoting pro-environmental behaviors by fostering resilience and self-efficacy in Iranian youth. Additionally, based on social cognitive theory, the research examines the role of sustainable youth social work in moderating these relationships.

Materials And Methods: A cross-sectional design was employed to collect data via a survey from 384 Iranian participants, using validated scales.

Comparison of Post-auricular Soft Tissue and Post-auricular Soft Tissue With Autologous Bone Pate in Obliteration of the Canal Wall Down Mastoidectomy Cavity.

Background The surgical management of chronic otitis media (COM) with squamous disease is canal wall down mastoidectomy (CWDM). Canal wall down procedures require the obliteration of the newly formed cavity to mitigate complications. Soft tissue flaps, including Rambo flap, Hong Kong flap, Palva flap, and inferior-based fascio-periosteal flap, as well as autologous bone pâté, have been the most successful and commonly used materials for obliteration over the past two decades.
