The document describes a floatable foundation made of recyclable materials that could be used to support dwellings in flood-prone areas. The foundation is made of 14 plastic bottles, a pallet, and rope. It functions by displacing its own weight in water through buoyancy provided by the air in the bottles and spaces in the pallet frame. Calculations show the prototype foundation could support over 100 pounds, enough for a small structure. The design aims to provide flood protection for areas like parts of South Africa that commonly experience flooding.

Ch.10 the roman republic-2003
Rome's location in Italy and its transition to a republic helped it become a major power. The geography of Italy made travel difficult but the climate allowed Rome's growth. Rome transitioned from a monarchy to a republic with three parts: magistrates, the Senate, and assemblies, which helped create stability. The republic expanded through wars against Carthage and others. Later crises included the Gracchi brothers' reforms threatening the wealthy and civil wars between Marius and Sulla and the slave revolt led by Spartacus.

2.3 A feeling for the numbers: microbes as the unseen majority
(a) Use Figure 2.1 to justify the assumption that a typical bacterial cell (that
is, E. coli) has a surface area of 6µm2 and a volume of 1µm3. Also, express
this volume in femtoliters. Make a corresponding estimate of the mass of such
a bacterium.
(b) Roughly 2–3 kg of bacteria are harbored in your large intestine. Make an
estimate of the total number of bacteria inhabiting your intestine. Estimate
the total number of human cells in your body and compare the two figures.
(c) The claim is made (see Whitman et al., 1998) that in the top 200m of
the world’s oceans, there are roughly 1028 prokaryotes. Work out the total
volume taken up by these cells in m3 and km3. Compute their mean spacing.
How many such cells are there per milliliter of ocean water?
(a) E. coli has (roughly) the shape of a cylinder that is 2 µm in length and 0.5 µm
in radius. For those that are so inclined, the bacterium can alternatively be
treated as a spherocylinder, though the results will not change in any interesting
way. Using these numbers we calculate the area of an E. coli to be:
Acell = ⇡ ⇥ 1 µm⇥ 2 µm ⇡ 6 µm2. (2.28)
Its volume is:

If we assume that the density of a bacterium is the same as that of water, the
mass of one bacterium is 103kg/m3 ⇥ 10�18 m3 ⇡ 10�15 kg = 1 pg.
(b) The fact that each bacterium has a mass of 1 pg implies that 2�3 kg worth
of bacteria in the intestines of one person amounts to 2 ⇠ 3⇥ 1015 bacteria.
Assume that the size of a typical human cell is roughly 10 µm in diameter and
has a spherical shape with the same density as that of water. Let’s assume that
the mass of a “typical” human body is roughly 80 kg. Further, let’s assume
that thirty percent of the human mass corresponds to cells. On the basis of
these assumptions, we find that the number of the cells in a human body is
approximately

cells by more than a factor of ten.
(c) Using (a) we can estimate the volume of 1028 prokaryotes to be about

the mature virion in fig. 2.31(C) shows that the CA proteins come together to
form the capsid with inward pointing “spokes,” in the same way that the GAG
polyproteins form the initial outer shell of the virion. This means that CA and
GAG have the same surface areas per protein. Because the surface area of the
capsid is less than that of the virion and because each CA protein is cleaved o↵
a GAG polyprotein, this fact immediately implies that not all the CA proteins
can be used up to form the capsid.
From the micrographs, the capsid can be approximated as a cone with base

It begins with examples calculating the mass, weight, density, and pressure using given values. Later examples apply concepts like buoyancy, pressure at depths, and pressure transmission using hydraulic jacks. Key formulas introduced include pressure (p=F/A), fluid pressure (p=hρg), and buoyancy (B=Vfluidρfluid). Overall, the document provides practice problems and solutions for understanding fundamental fluid statics principles.
Compaction and Drain-ability
Compaction increases the density and engineering properties of soils through mechanical means. The standard Proctor test determines the optimum moisture content and maximum dry density of a soil through compacting specimens at different moisture contents and measuring their dry densities. Higher compactive effort through modified Proctor testing results in higher densities. Well-compacted soils have increased shear strength and reduced compressibility, permeability, and liquefaction potential. Laboratory compaction curves may differ from field compaction due to degradation and replacement of oversized particles in the lab. The structure and properties of compacted fine-grained soils, like permeability and compressibility, depend on the compactive effort and proximity to the optimum moisture content.

Fun with EMC2
1) A liter of water contains enough mass to produce 9 x 1016 Joules of energy if converted entirely, which could power a 1 Watt lightbulb for around 3 billion years.
2) The sun produces its energy through nuclear fusion, where hydrogen nuclei fuse into helium. A little bit of mass is lost in this process, appearing as energy according to E=mc2.
3) Scientists are trying to create controlled nuclear fusion on Earth for a sustainable energy source, but it requires maintaining temperatures over 15 million degrees, which is technically challenging.
Solid and fluid
This document discusses the characteristics of solids, liquids, and gases. It defines solids as having a fixed shape and volume with particles that are closely packed and vibrate. Liquids are defined as having a fixed volume but not a fixed shape, with particles that are closely packed and can move randomly. Gases are described as not having a fixed shape or volume, with particles that are widely spaced and move freely. The document also covers density, pressure, Pascal's principle, Archimedes' principle, and provides examples of calculating density, pressure, buoyant force, and more.
Blue planet lrg
This document summarizes why Earth is called the "Blue Planet". It states that water covers over 70% of Earth's surface, with oceans accounting for 361.8 million km2, making Earth appear blue from space. Water absorbs red light much more than blue light, and the scattering of blue light over red contributes to the blue color of oceans, lakes and rivers when viewed from above. The document also notes that water is made up of hydrogen and oxygen atoms and can exist as a liquid on Earth between 0-100 degrees Celsius.
Reduce Evaporation Losses from Water Reservoirs
Evaporation suppression is the reduction of evaporation bycontrolling the rate at which water vapor escapes from water surfaces. The need for water saving is greatest in areas of little rainfall and low runoff. Water losses by evaporation from storage reservoirs must be minimized for greatest utility of limitedsupplies. Using trash of polyethylene with different densities (800, 875 and 900 kg/m3) as floating cover to the water filling cylindrical container with 8 cm diameter led to reduce the evaporation rate. A suitable trash density of 800 kg/m3 gave reduction in evaporation rate of 57% from the theoretical results calculated using equation (4) which is a good result if compared with previous researches
