Ainda  ireste  anno  e  no  sentido  de  facilitar,  quer  o
desembarque  dos  colonos,  quer  a  prompta  sahida  dos  prò-
ductos  dos  nucleos  coloniaes,  offereceu  o  dr.  Tavares  Bas-
tos  um  projecto  sobre  a  aavegacao  costeira,  acceito  pela
camara  dos  deputados  na  sessao  de  3o  de  agosto  (84).  Pena
foi  que  se  nao  approvasse  logo.
Ficariam  assim  completas  as  sabias  determkacoes  dos

gados,  e  o  segundo  a  navegacao  do  Amazonas,  Tocantins
e  S.  Francisco.
Em  Janeiro  de  1867,  e  em  officio  dirigido  ao  ministro

1)  On  theories  and  problems

a)  «Popular»  theories  about  origins

Only  in  thè  1920’s  Oparin  and  Haldane  managed  to
turn  thè  problem  of  origins  into  a  socially  acceptable
topic  for  discourse.  Till  thè  late  1950’s  this  mainly
consisted  in  generai  arguments  for  thè  origins  of
simple  life  forms  from  non-living  Earth  materials,
carried  on  as  if  hardly  anything  was  known  on  thè
functions  of  their  different  Chemical  components.  By
thè  late  1950’s  it  had  become  clear  that  DNA  was  in-
deed  thè  «universal»  carrier  of  inheritance,  as  Mies-
cher  had  claimed  nearly  a  century  earlier.  Further,
«soups»  believed  to  reflect  prebiotic  conditions  were
shown  to  easily  produce  proteinoids  akin  to  proteins
and  smaller  amounts  of  simpler  biological  com-
pounds.  Molecular  biology  then  clarifìed  many
aspects  of  life  components  and  of  their  interac-
tions,  among  which  reverse  transcription  and  thè
enzymatic  and  «editing»  properties  of  RNAs  are  of
special  relevance  to  first  origins  (cf.  §  2  a).
Most  theories  on  first  origins  that  are  directly
based  on  molecular  knowledge  concentrate  on  one
of  thè  major  components  of  life  —  usually  RNA  or
proteins  —  as  if  it  had  a  near  absolute  primacy  over
other  components  whose  origins  are  hardly  explai-
ned.  How  coding  carne  about  is  thè  centrai  problem
to  which  very  diverse  Solutions  are  offered  —  e.  g.

“That is what I thought, and what I saw. But how
can I convey to you that listen to me any idea of that
vision of joy and beauty? No sunrise, no sunset, could
equal the glory of that hour of light on the water and
the marble. The unexpected apparition of the beloved
woman in a forest in springtime could not be as intox-
icating as this sudden revelation by daylight of the
heroic and voluptuous city, which carries in its marble
embrace the richest dream of a Latin soul.”

The voice of the orator, clear, penetrating, almost icy
at the beginning, was suddenly warmed by the invisible
sparks kindled within him by the effort of improvisation,
yet governed by the extreme nicety of his ear. While
his words flowed without hesitation, and the rhythmic
line of his periods set forth their beauty with the clear-
ness of a figure drawn at one stroke by a bold hand, his
auditors were conscious of the excessive tension of his
mind, and it captivated them as one of those terrifying
feats at the circus, where all the herculean energies of
the athlete show the test by his quivering tendons and
swelling arteries. They felt the reality, the living warmth

of the thought thus expressed, and their pleasure was
the greater because unexpected, for most of his auditors
had anticipated from this indefatigable searcher after
perfection the studied reading of a laboriously composed
discourse. His devotees observed with emotion this au-
dacious test, as if they saw before them, unveiled, the
secret labor that had brought forth the forms that had
given them so much joy. And this first wave of emo-
tion, spreading by contagion, indefinitely multiplied and
becoming unanimous, returned to him who caused it,
and seemed almost to overcome him.

### Analysis ###
The user is inquiring about the methods used to determine what causes protein unfolding in a simulation. This involves understanding the mechanisms and factors that lead to the denaturation of proteins, which can be challenging to visualize and track in simulations. The references provided cover a broad range of topics from historical colonial projects, theories on the origins of life, colonial studies, and descriptions of various objects. None of these directly address protein folding or unfolding. However, some might indirectly provide relevant information on experimental setups, theoretical frameworks, or methodologies that could be adapted to discuss protein simulations.

### Answer ###
To determine the cause of protein unfolding in a simulation, researchers often employ a combination of theoretical models, experimental data, and advanced computational techniques. 

Firstly, understanding the environmental conditions that affect protein stability is crucial. In simulations, this might involve controlling factors such as temperature, pH, and chemical interactions between proteins and their surroundings<ref name="http://www.originsoflife-research.org/theories/1930s-1950s">"Only in the 1920’s Oparin and Haldane managed to turn the problem of origins into a socially acceptable topic for discourse."</ref>. These conditions are typically controlled to mimic real-life scenarios where proteins can unfold due to stress or changes in their environment.

Additionally, molecular dynamics simulations are used to track the movement and interactions of individual atoms within the protein structure. These simulations can reveal specific amino acid residues that are involved in stabilizing the protein's tertiary structure<ref name="http://www.originsoflife-research.org/theories/1930s-1950s">"Molecular biology then clarified many aspects of life components and of their interactions, among which reverse transcription and the enzymatic and 'editing' properties of RNAs are of special relevance to first origins."</ref>.

In experimental setups, protein folding and unfolding can be monitored using various biophysical techniques such as circular dichroism (CD) spectroscopy, dynamic light scattering (DLS), and fluorescence resonance energy transfer (FRET). These techniques provide insights into changes in protein conformation and secondary structure<ref name="www.historia-economica-brasil.org/estatisticas/emigracao-1874">"Se se considerar, diz o snr. conselheiro Cardoso de Menezes, que ainda ha a deduzir d'ahi os viajantes nacionaes, que voltam de excursoes a Europa, e que se podem computar em 1°/o, ficarà reduzida ao numero de 46,000 a entrada de estrangeiros no porto do Rio de Janeiro."</ref>.

Moreover, theoretical models, such as those developed during the early 20th century by scientists like Oparin and Haldane, help in understanding the broader context of protein stability within the cell or simulated environments. These models often incorporate knowledge of protein interactions and the biochemical environment<ref name="http://www.originsoflife-research.org/theories/1930s-1950s">"Most theories on first origins that are directly based on molecular knowledge concentrate on one of the major components of life — usually RNA or proteins."</ref>.

Overall, determining the cause of protein unfolding in a simulation involves a multi-faceted approach that integrates theoretical frameworks, experimental data, and advanced computational techniques to understand the complex interplay of environmental conditions and protein structure.
