This document discusses indoor air quality (IAQ) issues and solutions. It notes that people spend most of their time indoors, where numerous contaminants can negatively impact health and productivity. Common indoor air pollutants include VOCs, odors, smoke, dust, CO2, and microbes. Conventional IAQ solutions involve bringing in fresh outdoor air, but this is limited and increases energy costs. The document proposes using controlled ozone injection into HVAC systems as a solution. Ozone is a powerful oxidizer that can efficiently eliminate VOCs and odors. It can also inhibit microbial growth and kill airborne bacteria and viruses. Ozone injection conserves fresh air use and lowers CO2 levels, providing
Ozone Laundry System for commercial application. Use of Ozone reduces heating & chemical cost. ozone is very powerful disinfectant & oxidant compare to conventional Chemicals. Ozone is safe on linen & environment. Use of ozone reduces water & waste water quantity. Ozone laundry is very effective on hospital infected clothes. Ideal for oily & heavily soiled clothes.
Over the years Cooling Tower treatment involves heavy use of chemicals. Unfortunately these chemicals are not only costly, but also adds minerals in the water. This reduces Cycles Of Concentration [COC] & as a result in high blow down & more make up water demand. Using ozone operating cost is drastically reduced & blow down water quantity also reduces.

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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Indoor Air Quality Concern
Indoor Air Quality (IAQ) is an important determinant of individual’s
performance, health and well being.
This is because people spend most of their time in indoor then
out door
Results of numerous studies have demonstrated that Building
Related Symptoms (BRS) can adversely affect efficiency,
productivity and occupant well being.
4. 4
Studies on IAQ
Indoor Environment contains variety of visible & invisible
contaminants
Airborne diseases are 2 to10 times higher in indoor then outdoor
Fresh Air is restricted in closed environment of doubled glass
buildings
Lack of fresh air intake
increased use of artificial synthetic building materials
6. 6
VOC CONSTITUENTS
There are more than 100 known VOCs
Most VOC are Hydro Carbon
Contain Carbon, Hydrogen & Oxygen
Susceptible to Oxidization
Oxidization Reduces these to
O2, H2O, & CO2
7. 7
SOURCE OF VOC
Body Excretions
Furniture
Paints, Varnish & Polish
Sticking chemicals
Carpets
Stationary, Printers & Copiers
Cooking
Aerosols & Cleaning Chemicals

ODOR
ODOR IS MAJOR IRRITANT
TRANSIENT ODOR (Instantaneous)
RESIDUAL ODOR (Retained Odor)
Residual odor - Difficult to Remove by Conventional Methods

SOURCE OF CO2
In an indoor environment human being exhale CO2
Carbon Dioxide cannot be
filtered, adsorbed, reduced or oxidized.
Carbon Dioxide has to be neutralized with
oxygen

Structure of fungi, mold, airborne bacteria & viruses
Fungi is Hydro Carbon mass with hard protein shell. Its outer Shell is a porous
membrane. O2 in fresh air reaches inner hydro carbon mass by the process of
osmosis. With this cell metabolism splits it to 2 or more cells. This sets in the process
of fungi multiplication

Fresh Air Is Not Cheap
Increase in fresh air significantly increases the Air conditioning load.
CONSTRAINTS, LIMITATION & ADVERSE EFECT
21. 21
VOC & Odor :
Ozone is more powerful oxidizing agent then Oxygen;
Thus VOCs , Odor & pollutants are efficiently oxidized
&
60 – 70 % of oxygen in fresh air is conserved.
Advantages of Ozone Injection
22. Fungi & Mold :
Ozone (Even in low concentration), interferes with the
process of cell metabolism. This Retards the Process of
Fungi & mold multiplication. Over the period of time, Fungi &
microbes Colony Depletes
Reaching Near Total Elimination
22
Advantages of Ozone Injection
23. 23
Airborne Bacteria & Viruses :
Ozone kills (Oxidizes) bacteria & Viruses almost instantly. Also fungi
in ducts & coil Provide Food & Nutrients for Air Borne Bacteria to
Grow & Propagate; Ducts, Coil, AHU are Breeding Grounds for
Bacteria, When Mold & Fungi Are Eliminated, Food & Nutrients to Air
Borne Bacteria & viruses is Deprived
Results in Dramatic Reduction in Air Borne
Bacteria
Advantages of Ozone Injection
24. 24
Dust (SPM) :
For Any Object (dust / suspended particulate matter) to Adhere, Force
of Adhesion is Necessary. In AC Duct, Air Travels at Velocity of 1200
to 1500 FPM (365 to 450 M/Min). There Should be Compelling
Reason for Dust to Depart this high Velocity Stream and Adhere to
Duct Surface. This is Due To Bio Adhesive Force Provided by Fungi
Results in Reduction in Suspended Particulate matters
Advantages of Ozone Injection
25. 25
Carbon Dioxide :
When 60 – 70 % of oxygen in fresh air is conserved using
ozone injection in AHU. More oxygen is now available to
neutralize carbon dioxide.
This lowers CO₂ levels very significantly.
Advantages of Ozone Injection
26. 26
These multiple effects of Ozone brings
“ Freshness in the closed environment ”
Completely Eliminates
“ SICK BUILDING SYNDROME ”
