BIOCHEMISTRY: WEEK 12




Thousands of people who left Fukushima after the nuclear catastrophe are on the brink of being returned to contaminated areas due to withdrawal of government subsidies.  Residents are forced to either move back to homes they believe are unsafe or succumb to financial hardship without help from the government.

The Fukushima incident has resulted in unanticipated issues that involve socioeconomic problems and safety concerns amongst the displaced.  I can't imagine living in limbo since the aftermath of the nuclear meltdown.  Families are faced with not only financial difficulty, but also the fear of exposure to residual radiation upon returning to the Fukushima area.  Women and children have also been greatly impacted by the disaster since they were the primary group that fled the area.  Men were more apt to stay in order to keep their jobs in the Fukushima area.





Plant cell structure is different from an animal cell because it does not contain centrioles, lysosomes, intermediate filaments, cilia or flagella.  Specialized structures such as a rigid cell wall, central vacuole and chloroplasts also characterize plant cells. The rigid cell wall is more complex than an animal cell because it functions to regulate the life cycle of the plant.  A central vacuole serves to store compounds, support growth and provide a structural role.

The cell structure of a plant makes it a unique part of Earth's ecosystem.  All animal life is dependent on plant life since they provide food, shelter and medicine for survival.  Plants also absorb carbon dioxide from the atmosphere and help to keep the air clean.  In terms of soil quality, they prevent soil erosion and enrich the soil with nutrients.  The specialization of the plant cell makes it an important foundation for the earth's biosphere.

PHYSICS: WEEK 10

When an object has symmetry, it can be divided into two pieces which are mirror images of each other.  Although we are always striving for symmetry, there is an underlying asymmetry within everything.  As an esthetician, I find this in my work on a daily basis.  Clients come to see me hoping that they can turn their brows into the perfect symmetrical work of art.  I do my best to perfect the mirror imaging of their brows but in reality, there is always some form of asymmetry no matter what.  I believe that we seek symmetry in our daily lives because it is built into our DNA.  We see this in art, music and all that we create.  Our animal instincts recognize that the symmetry reflected in facial features and bodily proportions is a better indicator of good health, so prospective mates may be chosen for healthier offspring.  Symmetry is also equated with the divine in many religions since it represents the ultimate perfection.  Through our cr...

RACHELLE'S PHYSICS BIO

I was born and raised in Honolulu, Hawaii and have been living in the Bay Area with my family since 2004.  I've worked an esthetician for the past decade by helping clients achieve their skin care goals.  I am now dedicated to being a student in Chinese medicine school and fulfilling an interest that was sparked long ago as a young child in my grandmother's kitchen.  She brought her knowledge of village medicine from China to the United States and used it in our household to treat various illnesses and ailments.  I am hopeful that my current journey will be a bridge for the knowledge of the inner and outer landscapes of the human body.

Organized chaos can be described as the process of gaining desirable outcomes through a state of disorder.  This might reveal a hidden natural order that governs all living things, even when the environment seems chaotic.  If we think of the principles of yin and yang, we see that there is always an element of both within each other.  Therefore, chaos resides in order and order resides within chaos.  Organized chaos provides an environment for unpredictability and ultimately, creativity.  The lack of a system of rigid order results in numerous creative possibilities and outcomes.  Chaos can be seen as an environment of freedom that provides a breeding ground for systems of natural order to arise A fractal system is a complex, non-linear interactive system which has the ability to adapt to a changing environment.  Such systems are characterized by the potential for self organization, existing in a non-equilibrium environment.  Chan...
