Women in northern Kenya play an important role in livestock value chains but face barriers to full participation and empowerment. A study with 660 participants in Marsabit and Isiolo examined how empowering women through livestock interventions could improve maternal and child nutrition. The study found that women's time-consuming responsibilities negatively impact nutrition and market access. While women control income from livestock products, men predominantly control income from live animal sales. Increasing women's engagement in production and sale of livestock products may help improve feeding practices and nutritional status.

Lavoisier made important contributions to chemical nomenclature by proposing a new system of naming compounds. He was executed during the French Revolution despite his scientific achievements.
Antoine Lavoisier was a French nobleman chemist born in 1743 who played a central role in the chemical revolution of the 18th century. He attended lectures on natural science as a young man and was elected to the French Academy of Sciences at age 26. Lavoisier is considered the "Father of Modern Chemistry" due to his significant influence on the fields of chemistry and biology through his experiments and explanations of other scientists' work. He was executed by guillotine in 1794 after being convicted of tax fraud.
This document provides a summary of Antoine Lavoisier's contributions to chemistry, including:
1) Lavoisier disproved the theory of phlogiston through experiments showing that combustion reactions involve gases combining with oxygen rather than releasing phlogiston.
2) He established that water is a compound of hydrogen and oxygen by collecting and weighing the products of a combustion reaction.
3) Lavoisier is considered the founder of modern chemistry for his establishment of a system of chemical nomenclature and for listing the first table of chemical elements. He emphasized quantitative experiments and conservation of mass.
Louis Pasteur was born in 1822 in France. He had a successful career as a chemist and professor, making several important scientific discoveries around microbiology. Some of his key discoveries included proving that fermentation is caused by microorganisms, discovering that microorganisms can be both aerobic and anaerobic, and developing the process of pasteurization. Late in his career, he developed the first vaccines against rabies and cholera, saving many lives and establishing the field of vaccination. He died in 1895 and was buried at the Pasteur Institute in Paris.
The origin of the Discipline Biochemistry can be traced as far back as the 17th Century. The Discipline has since evolved and continues to play a pivotal role in the development of new technologies.
Louis Pasteur was born in 1822 in France and studied physics and chemistry, receiving his PhD in 1846. Some of his major discoveries included discovering that crystals could have mirror-image structures and that fermentation was caused by microorganisms like yeast. He developed the process of pasteurization to prevent spoilage in foods and beverages and was the first to create vaccines, successfully testing them against cholera in chickens and rabies in dogs. Pasteur made many contributions in microbiology and vaccinology that saved countless lives and established him as one of the most important scientists in history. He died in 1895 and was buried in Notre Dame Cathedral in Paris.
Louis Pasteur was born in 1822 in Dôle, France to a family that valued patriotism and hard work. He showed a talent for science from a young age and went on to study at the prestigious École Normale Supérieure in Paris. There, he made groundbreaking discoveries in crystallization and molecular asymmetry that laid the foundations for the new field of stereochemistry. Later in his career, Pasteur developed vaccines against deadly diseases like anthrax and rabies by growing them in sterile conditions. He also invented the process of pasteurization to prevent spoilage in foods like milk and wine by heating them, vastly improving public health. Pasteur founded the Pasteur Institute in Paris, where

The timeline covers many pivotal scientific advances over millennia that helped establish the foundations of modern chemical engineering.
Darwin developed his theory of evolution by natural selection based on observations from his voyage on the HMS Beagle. He saw that different species of finches on the Galapagos Islands had adapted to have beaks suited to the food available on their particular island. This led Darwin to realize that the mechanism of natural selection - where individuals with traits better suited to the environment tend to survive and pass on those traits - over many generations could explain the diversity of life without needing to invoke design. His theory revolutionized scientific thought by providing a naturalistic explanation for both microevolution within species and macroevolution between species over immense periods of time.

Antoine Lavoisier (1743-1794) was a French chemist who is considered the "Father of Modern Chemistry". He developed the first geological map of France and proved that elements are basic substances that cannot be broken down further. Lavoisier established that elements could be classified into metals and non-metals and drew up one of the first lists of elements. Although his early periodic table attempts were imperfect, his work helped scientists better understand and discover new elements. Despite his scientific contributions, Lavoisier was executed during the French Revolution due to political conflicts.
One of the first attempts to establish rules for botanical taxonomy was made by Augustin Pyramus de Candolle in 1813, stating that published names should have priority by date. However, the English did not follow this rule until adopting rules established by Alphons de Candolle in 1867. In response to nomenclatural issues caused by Kuntze, botanists established the first International Code of Botanical Nomenclature in 1905, setting 1753 as the starting point for name priority, the year of Linnaeus' Species Plantarum. The first zoological nomenclature laws were established by Hugh Edwin Strickland in 1842.

Paulo Freire was a Brazilian philosopher and the father of critical pedagogy who developed the concept of conscientization. Conscientization is the ability to critically perceive the causes of social, political, and economic oppression in order to take action against oppressive elements of society. It involves developing a deep understanding of the world that leads to freedom from oppression. Freire viewed education as a tool for liberation that should involve dialogue between students and teachers to develop a shared critical understanding of reality. His educational philosophy emphasized problem-posing education, dialogue, and using education to promote conscientization and liberation.

A chemical bond is an attraction between atoms that allows the formation of substances containing two or more atoms. The bond is caused by electrostatic forces of attraction, either between electrons and nuclei or due to dipole attraction. When metals bond to nonmetals, electrons from the metal atoms are transferred to the nonmetal atoms, resulting in the metal atoms becoming positively charged ions and the nonmetal atoms becoming negatively charged ions.

2. Beginnings
Antoine-LaurentLavoisierwas bornintoa privileged
familyonAugust26, 1743inFrance’scapitalcity,Paris.
His fatherwasJean-AntoineLavoisier,a lawyerinthe
ParisParliament.
His motherwasÉmiliePunctis,whosefamilywealth
hadcomefroma butcherybusiness. Shediedwhen
Antoinewasfiveyearsold, leavinghima largeamount
of money.
Betweentheagesof 11 and18, Antoinewaseducated
at CollègedesQuatre-Nations,a collegeofthe
Universityof Paris.Hestudiedgeneral subjects there,
includingthesciencesinhisfinaltwoyears.
Althoughhewas veryattractedtothesciences,he
enrolledinthecollege’slaw schoolat18, aimingto
pursuethesamecareeras hisfather.(Hisfatherhad
encouragedhimto believethatsciencewasmerelya
hobby, nota seriousprofession.)
Aftertwoyearsstudyinglaw,hewasawardeda
bachelor’sdegree.A yearlater,in1764,heobtaineda
licenseto practiceas a lawyer,butdecidedagainstthis.

Oxygen and Combustion
In 1772peopledidnotunderstandtheprocessof
burning.Theyhadinconsistent, confusedtheories, chief
of which was thetheoryof phlogiston,anundetectable
substancewhich sometimeshad negativemass!
We nowknow thatcombustionhappenswhen
substancesreactwithoxygenat hightemperatures.In
1772,however, whenLavoisierbeganworkinginthis
field,oxygen’sdiscoveryby JosephPriestleystilllay

In 1772Lavoisierdiscoveredthatwhenphosphorusor
sulfurareburnedinairtheproductsareacidic. The
productsalsoweighmorethantheoriginalphosphorus
or sulfur,suggestingtheelements combinewith
somethingintheairto produceacids.Butwhat?
In 1774Joseph PriestleyvisitedParis.HetoldLavoisier
aboutthegas producedwhenhedecomposedthe
compoundwenow calledmercuryoxide. Thisgas
supportedcombustionmuchmorepowerfullythan
normalair.Priestleybelievedthegas wasa particularly
pureversionof air. Hestartedcallingit
dephlogisticatedair,believingits unusual properties
werecausedby theabsenceofphlogiston.
Lavoisierdidnotbelieveitwas dephlogisticated
anything,becausehedidnotbelieveinphlogiston.
In 1779Lavoisiercoinedthenameoxygenforthe

andrespiration.Healsoconcludedthatwhen
phosphorus orsulfurareburnedinair,theproducts
areformedby thereactionof theseelements with
oxygen.
Antoine Lavoisier
6. Elementary Treatise on Chemistry
“Sulfur,whenburning,absorbs oxygengas;
theresultingacidis considerablyheavierthanthe
sulfurburned;itsweightis equalto thesumof weights
of thesulfurburnedandtheoxygenabsorbed.”
Sulfuris anelement
In 1777Lavoisiercorrectlyidentifiedsulfuras an
element.Hehadcarriedoutextensiveexperiments
involvingthis substanceandobservedthatitcouldnot
be brokendownintoanysimplersubstances.
TheConservationof Mass
In 1778Lavoisierfoundthatwhenmercuryoxideis
heateditsweightdecreases.Theoxygengasitreleases
has exactlythesameweightas theweightlostby the
mercuryoxide.
Whilethismay seemobviousto us today, itwas lessso
in thosedays(hencethegeneralsupportforthe
phlogistontheory).Aftercarryingoutworkwitha
numberofdifferentsubstances,andrecallingearlier

7. announceda new fundamentallaw ofnature:thelaw of
conservationofmass:
matteris conservedinchemicalreactions
or statedinanotherway:
thetotalmassof a chemicalreaction’sproductsis
identicaltothetotalmassof thestartingmaterials
It is oftensaidthatLavoisierwasthefirstscientistto
statetheprincipleofmassconservation. Thisis not
strictlyincorrect.In1630 JeanReyhadformulateda
similarlaw;in1755JosephBlackhadassumedthelaw
was trueinhisworkdiscoveringmagnesium;andin
1760MikhailLomonosovhadpublisheda statementof
thelaw.
Thelaw ofmassconservationonlybecamefirmly
establishedafterLavoisierindependentlydiscoveredit.
“In performing experiments, it is necessary… that
they be simplified as much as possible, and that every
circumstancethat could complicate theresults should be
completely removed.”
Combustion and respiration
8. Lavoisiersuspectedthatcombustionandrespiration
arechemically thesame.Hedemonstratedthis withthe
helpofPierre-SimonLaplace. Thepairmeasuredthe
amountof carbondioxideandheatgivenoffby a guinea
pigas itbreathed.They comparedthis totheamountof
heatproducedwhenthey burnedcarbontoproduce
thesameamountofcarbondioxideas hadbeenexhaled
by theguineapig.
TheirresultsallowedLavoisierto concludethat
respirationis a formof combustion. Theheatproduced
by mammals duringrespirationkeeps theirbodies
aboveroomtemperature.
Lavoisier measures the oxygen in air exhaled from a man’s lungs. Lavoisier’s wife Marie-Anne makes notes.A
skilled artist, she also created the engraving from which this image was taken.
Wateris not an element
In 1783Lavoisiercoinedthename‘hydrogen’forthe
gas which HenryCavendishhadrecognizedas a new
elementin1766;Cavendishhadcalledthegas
inflammableair.
9. WorkingagainwithPierre-SimonLaplace,Lavoisier
burnedhydrogenwithoxygenandfoundthatwater
was produced, establishingthatwateris notan
element,butis actuallya compoundmadefromthe
elementshydrogenandoxygen. Thisresultastonished
manypeople,becauseatthattime‘everyoneknew’that
waterwas itselfoneofthe‘indivisible’elements.
Hydrogen means water former in Greek.
“It required85partsby weightof oxygenand15partsof
hydrogento compose100partsof water.”
The Metric System
Starting in 1791, Lavoisierserved on the committee of
the French Academy of Sciences which developedthe
metric system of measurement. Other members of the
committee including the well-knownmathematicians
Pierre-SimonLaplaceand Adrien-MarieLegendre.
