This document discusses pilot plant design, operation, and scale up considerations for pharmaceutical manufacturing processes. It provides an overview of the need for pilot plants and scale up to transfer processes from the laboratory to production scale. Key sections include descriptions of pilot plant attributes, operational aspects like validation and training, scale up principles of similarity, and development milestones from formulation through clinical and commercial production. Process parameters that should be evaluated at various stages like mixing, drying, milling and compression are also outlined.
It is the part of the pharmaceutical industry where a lab scale formula is transformed into a viable product by development of liable and practical procedure of manufacture.

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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

33.
34. Material/Powder Handling
Two primary concerns : Achieving reliable flow and
maintaining blend uniformity.
Segregation leads to poor product uniformity.
Handling system :
- Must deliver the accurate amount of the
ingredient
- Material loss should be less
- There should be no cross contamination
35. Avoiding segregation …..
Modify the powder in a way to reduce its inherent tendency
to segregate
Change the particle size such that the active segregation
mechanism becomes less dominant
Change the cohesiveness of the powder such that the particles
in a bed of powder are less likely to move independent of
each other
Modify the equipment to reduce forces that act to segregate
the powder
Change the equipment to provide remixing
36. Dry Blending
Dry blend should take place in granulation vessel
Larger batch may be dry blended and then subdivided
into multiple sections for granulation.
All ingredients should be free of lumps otherwise it
causes flow problems.
Screening and/or milling of the ingredients prior to
blending usually makes the process more reliable
and reproducible.
37. GRANULATION

generated by granulation equipment.

terms of space and manpower requirements).

42. PARTICLE SIZE REDUCTION
Sizing plays a key role in achieving uniformity.
There are two ways of sizing : Particle size separation
and Particle size reduction.
Major Factor – Feed rate of the material.
During scale up, overhead feeding equipment is
incorporated to mimic large scale production.

While choosing size and type of pump :

Pumping pressure required should be considered
61.
62. PARENTERAL SOLUTION
It is liquid scale up task.
Mixing is one of the important process to be scaled up.
Large scale mixing -- Flow
Small scale mixing -- Shear
Geometric factors :-
-- Diameter of the impeller (D)
-- Diameter of the tank (T)
-- Height of the liquid in the vessel (Z)
-- Impeller speed
65. The design and Scale-up of biological processes is very
challenging.
Parameters to be considered for scale-up of biotechnology
products are :
1. Bioreactor Operation
2. Filtration Operation
3. Centrifugation
4. Chromatography
5. Viral Clearance
68. Other variables used in scale-up work for filteration are :
The length of the fibers (L)
The fiber diameter (D)
The number of fibers per cartridge (n)
The density of the culture (ρ)
The viscosity of the culture (μ)
From these variables, scale-up parameters such as wall shear rate
and its effect on flux are derived.

Gel Capacity
Linear Velocity
Buffer Volume
Bed Height
Temperature
Cleanability
Gel lifetime

70. VIRAL CLEARANCE
It is very important part of the process design for
biotechnology product.
It is also to be scaled up.
73. Similarity with respect to geometrical factors
i.e. shape, height, thickness, breadth, etc.,
Small scale and large scale equipments must be
in scale ratio of 1:2, 1:5, 1:20 etc.,
74. MECHANICAL SIMILARITY
Concerned with application of force to a stationary or moving
system.
Static similarity – It is the deformation of one body or
structure to that of an other under constant stress.
Kinematic similarity – Corresponding moving particles take
similar path in the corresponding time interval.
Dynamic similarity – Forces which accelerate or retard the
motion of materials.
Moving systems are dynamically similar when the ratio of
all forces is equal.
It is useful in the prediction of pressure drops, power
consumption.
76. THERMAL SIMILARITY
It is concerned with flow of heat (by radiation,
conduction, convection, or the bulk transfer of
material).
Geometrically similar systems are thermally similar
when temperature difference bears constant ratio and
in moving systems it must have Kinematic similarity.
77. CHEMICAL SIMILARITY
It is concerned with the variation in chemical
composition from point to point as a function of
time.
It is related to existence of comparable concentration
gradients.
It is dependent upon both thermal and Kinematic
similarity.
