This document discusses the phase rule, which describes the behavior of heterogeneous systems in equilibrium. The phase rule states that the number of degrees of freedom (F) in a system equals the number of components (C) minus the number of phases (P) plus two. A phase is a homogeneous part of a system that has uniform physical and chemical properties throughout. Phase diagrams can be used to predict how changing temperature, pressure, and concentration will affect a heterogeneous system in equilibrium.

The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

PHASE RULE
WHAT IS MEANT BY PHASE
WHAT IS MEANT BY COMPONENTS
DEGREES OF FREEDOM
DERIVATION
ONE COMPONENT SYSTEM
PHASE DIAGRAM
2. PHASE RULE
THE PHASE RULE IS AN IMPORTANT
GENERALIZATION DEALING WITH THE
BEHAVIOR OF HETEROGENEOUS SYSTEM.
IN GENERAL IT MAY BE SAID THAT WITH THE
APPLICATION OF PHASE RULE IT IS POSSIBLE
TO PREDICT QUALITATIVELY BY MEANS OF
DIAGRAM. THE EFFECT OF CHANGING
PRESSURE , TEMPERATURE AND
CONCENTRATION ON A HETEROGENEOUS
SYSTEM IN EQUILIBRIUM.
3. HETEROGENEOUS EQUILIBRIUM IS
FIRST DISCOVERED BY AMERICAN
PHYSICIST “WILLARD GIBBS” IN 1874.
IT MAY BE MATHEMATICALLY STATED
AS:
F=C – P+2
F= DEGREE OF FREEDOM
C=COMPONENTS
P=NUMBER OF PHASES OF THE
SYSTEM
4. PHASE
IT MAY BE DEFINED AS:
“ANY HOMOGENOUS PART OF A SYSTEM HAVING
ALL PHYSICAL AND CHEMICAL PROPERTIES THE
SAME THROUGHOUT”.
A PHASE MAY BE OF THREE TYPES:
1. ONE PHASE SYSTEM
2. TWO PHASE SYSTEM
3.THREE PHASE SYSTEM
5. A SYSTEM CONSISTING OF ONE PHASE IS
CALLED HOMOGENOUS SYSTEM.
A SYSTEM CONSIST OF TWO OR MORE
SYSTEM IS CALLED HETEROGENOUS
SYSTEM.
GENERALY,LIQUID SLOID GASES ARE
THREE PHASES BUT IIN PHASE RULE “A
UNIFORM PART OF A SYSTEM IN
EQUILIBRIUM IS TERMED AS A PHASE.
6. EXAMPLES:
1.PURE SUBSTANCES, MAY BE LIQUID, SOLIS OR GAS
FORM 1 PHASE.
E.G, OXYGEN,BENZEN AND ICE ARE 1- PHASE.
2.MIXTURE OF GASES, IS ONE PHASE SYSTEM.E.G, ANY
MIXTURE OF GASES LIKE OXYGEN AND NITROGEN FORN
1-PHASE.
3.MISCIBLE LIQUIDS, TWO MISCIBLE LIQUIDS FORM ONE
PHASE.E.G, SOLUTION OF WATER AND ETHANOL IS ONE
PHASE SYSTEM.
4.NON-MISCIBLE LIQUIDS,SOLUTION OF TWO NON
MICIBLE LIQUIDS FORM TWO SEPRATE LAYER N IT WILL
2 PHASE SYSTEM.E.G, MIXTURE OF CHLOROFORM AND
WATER CONSTITUTE 2-PHASE SYSTEM.
7. 5.AQUEOUS SOLUTION,AN AQOUES SOLUTION
LIKE WATER+ SUGER FORM AQUEOUS SOLUTION
AND IT WILL ONE PHASE SYSTEM.
BUT SATURATED SYSTEM OF THAT SOLUTION
WILL FORM 2 PHASE SYSTEM.
AQOUES SOLUTION OF SODIUM CHLORIDE IS 1-
PHASE SYSTEM WHILE ITS SATURATED SYSTEM
FORM 2-PHASE SYSTEM
6.MIXTURE OF SOLIDS:
A. A PHASE HAVE SAME PHYSICAL AND CHEMICAL
PROPERTIES.
A MONOCLINIC AND RHOMBIC SULPHUR ARE TWO
ALLOTROPIC FORMS WHICH ARE CHEMICALLY
SAME BUT PHYSICALLY DIFFERENT AND FORMS 2-
PHASE SYSTEM.
8. B. A MIXTURE OF TWO OR MORE CHEMICAL
SUBSTANCES CONTAINS AS MANY PHASES.EACH
OF THEM HAVE DIFFERENT CHEMICAL AND
PHYSICALL PROPERTIES.
A MIXTURE OF CALCIUM CARBONATE AND
CALCIUM OXIDE FORM TWO PHASES.WHILE THE
DECOMPOSITION OF CALCIUM CARBONATE
FORMS 3 PHASE SYATEM
9. WHAT ARE COMPONENTS ?
Defination:
The least number of independent chemical
constituents in terms of which compostion of
every phase can be expressed by means of a
chemical equation
10. RULES FOR FINDING A COMPONENT:
Chemical formula representing the composition of a phase
is written on LHS.
Rest of chemical constituents that are represented in
chemical equation are written on RHS.
If quantities on RHS are made minus or zero then we get
compostion of phase on LHS.
11. NUMBER OF COMPONENTS IN A SYSTEM:
1-Component System:
Only 1 constituent forms the compostion.
Example :
Water
Suplhur
(ice) (water) (vapours)
12. 2-Component System:
When two components independently form a compostion then it is 2-
component System.
• Example:
(i) Mixture of two gasses like 02 and N2
Phase Component
Mixture of two = xO2 + yN2
Gases
(ii) Sodium Chloride Solution:
Phase Component
Aq. Sol of = xNaCl + yH2O
NaCl
13. (iii) Saturated Sol Of NaCl:
Phase Component
Aq.Sol of = xNaCl + yH20
NaCl
Solid NaCl = NaCl + 0H2O
(iv) Decomposition Of Calcium Carbonate:
Equation:
CaCO3 ⇌ CaO + CO2
(solid) (solid) (gas)
Phase Component
CaCO3 = CaO + CO2
CaO = 0CaCO3 + CaO
CO2 = CaCO3 – CaO
14. SATURATED SOLUTION OF NACL
Mixture of Aq. NaCl and Solid NaCl to form
saturated solution .That is a 2-Component System.
15. (v) Decomposition Of Ammonium Chloride:
Ammonium Chloride when heated in a closed vessel exisits in
equilibrium with the products of dissociation,ammonia and hydrogen
chloride gas.
Equation:
NH4Cl ⇌ NH3 + HCl
(solid) (gas) (gas)
Phase Components
Solid = NH4Cl
Gaseous = xNH3 + xHCl or NH4Cl
Thus dissociation of Ammonia is a 2-component system.
16. DEGREE OF FREEDOM :
The least number of variable factors
(concentration,temperature,pressure) which
must be specified so that the remaining
variables are fixed automatically and the
system is completely defined.
17. F=0 Non variant.
F=1 Univariant.
F=2 Bivariant.
A system is defined completely when it retain
the same same state of equilibrium with the
specified variables.
18. For a pure gas F=2 :
a system containing a pure gas has two
degree of freedom.
For a mixture of gases F=3:
a mixture of gases has 3 degree of
freedom (F=3)
For water ⇌ water vapours, F=1:
the system containing water has 1
degree of freedom.
19. For saturated NaCl Sol, F=1
NaCl ⇌ NaCl-Solution ⇌ water vapours
the system has 1 degree of Freedom .
For ice-water -vapour System:
ice ⇌ water ⇌ vapours.
It has no degree of freedom so F=0
20. DERIVATION OF THE PHASE RULE
The states of a system will depend upon a
temperature and pressure and these
variables are always there .
The concentration,however,depend upon the
number of phases.
The total number of variable of the system:
[P(C-1)+2]
21. Thermodynamic Equilibrium:
when a system is in equilibrium the partial
molal free energy of each constituentsof a
phase is equal to the partialmolal free
energy of the same constituents in every
phase.
F=No. of variables – No. of Equations
= [P(C-1)+2] – [C(P-1)]
= PC-P+2-PC+C
F= C-P+2
22. PHASE DIAGRAM
Plot showing the conditions of the pressure
and temperature under which two or more
physical states can exist together in a state
of dynamic equilbrium.
23. CHARACTERISTIC FEATURES:
1. Region or Areas:
Devided into solid liquid and gases.
2. Lines or Cures.
That separates two phases
3. Triple Point.
A triple point shows the conditions under which
all the three phases(solids liquid vapours) can
coexist in equilibrium.
