Manufacturing Process
Some pearlising agents are waxy solids at ambient temperature and require melting in a drum oven or similar before use.
Demineralised water is most commonly used in order to minimise contamination of the product.
No further processing is required after blending, and the product may be packed off directly from the mixing vessel.
Manufacturing Process
For preparing liquid shampoo,
Triethanalamine lauvyl sulfate,
stearic acid are heated to about 650C.
Water & preservatives are also heated to 650C.
Both the solutions are mixed together and then cooled.
Perfumes are added after that. The shampoo thus prepared is bottled by automatic bottle filling machine.
Quality Control Tests
a)Foam Stability
Cylinder shake method was used for determining foaming ability.
50ml of the 1% shampoo solution was put into a 250ml graduated cylinder and cover the cylinder with hand and shaken for 10 times. The total volumes of the foam contents after 1 minute shaking were recorded. The foam volume was calculated. Foam should retain for atleast 5mins.
Foam Stability = V2-V1
Quality Control Tests
b)Skin – irritation Test:
Draize test in Rabbits where a patch test technique is used on the intact skin of Albino Rabbits.
A set of 6Rabbits used for testing each material.
Shampoos should be tested only for a short duration thatis,not more than(NMT)4hours as these products come in contact with skin only for a short duration.
These preparations are diluted between concentrations of 8 to 10%.
Quality Control Tests
c)Wetting Action:
Canvas disk is used, is one inch in diameter is floated on the surface of a solution and the time required for it to sink is measured accurately.
Quality Control Tests
d)Viscosity:
Is determined using Brookefield Viscometer.
100ml of shampoo is taken in a beaker and spindle is dipped in it for about 5min and then reading is taken.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.

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.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .

• These products are evaluated for the contents estimation and their
identification, also some other tests are required which are to be done
according to purpose.
1. Antiseptic property: This can be done by in-vitro anti
microbiological test against some specific organism using liquid &
solid medium.
2. Stability test: Stability of products and the ingredients must be
studied, particularly that deals with effects of heat & light etc. It is
well known that most of the phenolic materials will discolour on
exposure to light & thus make fair hair, dark particularly in the

perform toxicity test along with other test including identification of
ingredients and estimating their quantity.
1. Estimation of hair removing agents: As high concentration of the
chemical hair removers may be dangerous, it is necessary to
remove the quantity. It can be done by any instrumental chemical
analysis.
2. Toxicity test: The test can be done on animal. For this purpose
rabbit can be used . Preparation can be applied for hair removal and
the effect on the skin can be studied by observation or by
