This experiment is about the motion of identical discs
that are stacked on top of each other if we apply a sudden
horizontal force to the bottom disc, the tower might remain
standing.
When the sudden force is applied to the tower, other discs
will start to move versus each other. If the center of mass of
the discs passes through the last point of the bottom disc
more than a critical time, the tower will topple because of
the torque which is applied to the discs of the tower.

The problem statement says “ A simple Cartesian diver
(e.g. an inverted test tube partially filled with water) is
placed in a long vertical tube filled with water. Increasing
the pressure in the tube forces the Cartesian diver to sink.
When it reaches a certain depth, it never returns to the
surface even if the pressure is changed back to its initial
value. Investigate this phenomenon and how it depends on
relevant parameters.”

In postural deformities, there is an imbalance in the loads
imposed on different areas. Where loads exceed normal
physiological limits consistently and over prolonged
periods of time, structural changes occur in the skeletal
bones. These structural changes cause postural
deformities, such as: genu valgum, genu verum,
asymmetric shoulders, Kyphosus and etc.

In magnet science, scientists achieved an extreme
progress. We have many famous laws and famous
scientists in this science, such as: Faraday’s law, Lenz law,
Joseph Henry (inductance), Hans Christian Oersted
(magnetic fields).

Coronaviruses that can infect animals and humans and
cause respiratory distress; these discomforts may be as
mild as a cold or as severe as pneumonia. In rare cases,
animal coronaviruses infect humans and then spread
between them. You may remember the SARS virus from
2002 to 2003; The virus was an example of the corona
virus, which was transmitted from animals to humans.
Another important and newer breed of the virus is the
coronavirus, which was discovered in the Middle East in
2012 and, according to scientists, the virus was first
transmitted from camels to humans, and the new virus,
Covid 19 or SARS Covid 2, which is an acute respiratory
syndrome.

Four Loko® is an energetic beverageconsumed by young
people in parties and social events, it contains 12% alcohol,
wormwood, furfural and taurine between others. This
beverage has been banned in several countries for its
secondary effects. The deputy María Mercado Sánchez
requested Cofepris to realize toxicologic studies for this
beverage since many young people have been hospitalized
by drinking it, and even launched an incitive to withdraw
it of the Mexican market.

At present, information and communication technologies
(ICT) have allowed a new form of interaction in the
teaching-learning processes. The rapid evolution of
computers and the growing use of mobile devices is
making both students and teachers use new media and
resources to enhance and acquire knowledge and thus
facilitate learning.

The Effect of Salt on Ice Melting

This problem tries to tell us how salt can melt ice and what
are these factors can affect this phenomenon. It relates to
our daily live, for example in winter when it snows, we
need to know which materials are better in terms of various
criteria such as the availability of material or the speed and
strength of melting snow and ice. First, we have to know
salt is a mineral composed primarily of sodium chloride
(NaCl), a chemical compound belonging to the larger class
of salts; salt in the form of a natural crystalline mineral is
known as rock salt or halite.

Accidents experienced by motorcycle drivers on curvy
roads are among the most frequently encountered news.
The vast majority of these accidents occur when the rider
loses control of the motorcycle while cornering as a result
of excessive leaning while cornering. Based on these
findings, it is aimed to develop a warning system that can
prevent motorcycle accidents in corners and inform the
user about the slope of the vehicle.

The main purpose of today’s education is; It should be to
raise people who can ask questions, say no, take critical
decisions, use initiative, have sufficient communication
skills, cope with new environments and establish new
relationships. Today’s individuals are not “knowledge
memorized” individuals who grew up in the traditional
school; must be “learning individuals”(Okutan, 2004).
The Coefficient of Restitution of Rebounding Capsules

When tablets collide during manufacturing and handling
operations they rebound with a force and velocity that is
determined by the collision conditions and the properties of
the materials. This collision rebound behavior of solid
bodies can be described using a parameter known as the
“coefficient of restitution” (CoR). The CoR varies with the
mechanical properties of both colliding bodies and is lower
for more plastic collisions and higher for elastic collisions.

If you are a researcher in biology laboratories, you are
definitely familiar with micropipette as one of the most
important equipment. Human error is an inseparable part of
an experiment. One of the most common human errors that
occurs when working with a micropipette is that the
sampled well is lost in a 96-well plate due to the proximity
of the wells, low transfer volumes…
