This document provides information on various techniques and technologies used in electrosurgery. It discusses the history and evolution of electrosurgery from the 1920s to present. Key aspects covered include the differences between electrocautery, electrosurgery, monopolar vs bipolar methods, and tissue effects. Complications are reviewed. Newer energy sources and technologies are introduced, such as advanced bipolar devices from Gyrus ACMI, Ethicon Endo-Surgery, and Covidien.

Presentation describing the modes of diathermy used in modern day surgery, its working principles, complications associated with diathermy use, precautions to be taken while using diathermy. Valuable for undergraduate students and post graduate residents of general surgery.
HARMONIC SYNERGY® Blades use high-frequency mechanical vibration to simultaneously cut and coagulate at the same time, sealing vessels at lower temperatures than electrosurgery:
Precise: Minimal lateral thermal tissue damage for safer dissection near vital structures
Reliable: Seals and divides vessels <= 2mm, as well as lymphatics
Versatile: Cuts, coagulates and dissects, reducing instrument exchanges
In operating room the most hazardous devise used in a daily basis is diathermy.
A basic understanding of electricity is needed to safely apply electrosurgical technology for patient care.

Haemostasis is very important in laparoscopic surgery. Vessel sealing with energy devises play a major role in keeping the surgical field clear. Energy devices are also used for tissue sealing and transection. Despite never types of energy devises electro-surgery is still very popular in gynaecological laparoscopy. Desiccation, dissection, and coagulation are the main effects of electro-surgery that are used for various purposes. Higher thermal injury with monopolar devices lead to the invention of bipolar devices with less tissue damage. Ligasure, pk gyrus, ENSEAL are some of the more advanced bipolar devices. Ultrasonic devices have the capability of coagulation and cutting tissues. During the process it can produce significant thermal injury. Thunderbeat combines bipolar and ultrasonic energy for coagulation and cutting respectively for more precise effects. Laser devices emit a beam of photons with a high degree of spatial and temporal coherence with tissue effects depending on the time of exposure and power density. CO2, Argon, Nd: YAG, KTP-532 are different laser types with different properties. Plasma is the fourth state of matter following solid, liquid and gas. Argon neutral plasma (System 7550TM ABC, Cardioblate) can produce energy in 3 forms including light, heat and kinetic energy. Laser and plasma energy are gaining more popularity for endometriosis surgery due to its localised effects and better preservation of ovarian follicles.
Instruments that apply energy to cut, coagulate and dissect tissue with minimal bleeding facilitate surgery. The improper use of energy devices may increase patient morbidity and mortality.
laparoscopy and minimal invasive surgery is modern gyn surgical tool tool it is wise to know some basics about electro- cauterization … and how to avoid its dangers.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
