Analysis of A Temporary Matter by Jhumpa Lahiri

A Temporary Matter A Temporary Matter is a story about grief and the secrets people keep from one another. Husband and wife Shukumar and Shoba are reeling from the loss of their child six months earlier. They avoid each other and their friends, Shoba filling her time with work and Shukumar procrastinating in finishing his dissertation. A deus-ex-machina in the form of systematic power outages allows for intimacy between the couple not achieved since the death of their son. The importance of communication within a marriage is a prevalent theme in  Interpreter of Maladies . Here the sorrow of the lost child causes a communication breakdown in the relationship of Shukumar and Shoba. This silence between them eventually destroys them because, in their grief, Shukumar and Shoba grow to become different people. Since they no longer share experiences, the couple grows apart. Their final secrets are painful ones – Shoba intends to move out and Shukumar violates the wishes of...

Blood Buffer System

Buffer A buffer is an aqueous solution that resists changes in pH upon the addition of an acid or a base . Also, adding water to a buffer or allowing water to evaporate from the buffer does not change the pH of a buffer significantly. Buffers basically constituent a pair of a weak acid and its conjugate base, or a pair of a weak base and its conjugate acid. Blood buffer The bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H 2 CO 3 ), bicarbonate ion (HCO3-), and carbon dioxide (CO 2 ) in order to maintain pH in the blood and duodenum , among other tissues, to support proper metabolic function. Catalyzed by carbonic anhydrase , carbon dioxide (CO 2 ) reacts with water (H 2 O) to form carbonic acid (H 2 CO 3 ), which in turn rapidly dissociates to form a bicarbonate ion (HCO3-) and a hydrogen ion (H + ) as shown in the following reaction. C O 2 + H 2 O ⇄ H 2 C O 3 ⇄ H C O 3 − + H + {\displaystyle {\rm {CO_...

Endosymbiosis

Endosymbiosis The hypothesized process by which prokaryotes gave rise to the first eukaryotic cells is known as endosymbiosis, and certainly ranks among the most important evolutionary events.  Endosymbiotic  theory, that attempts to explain the origins of eukaryotic cell organelles such as mitochondria in   animals   and fungi and chloroplasts in   plants   was greatly advanced by the seminal work of biologist Lynn  Margulis  in the 1960s. Mitochondria are one of the many different types of organelles in the cells of all eukaryotes. In general, they are considered to have originated from  proteobacteria  (likely  Rickettsiales ) through endosymbiosis. Chloroplasts are one of the many different types of organelles in the plant cell. In general, they are considered to have originated from cyanobacteria through endosymbiosis. Endosymbiosis has gained ever more acceptance in the last half century, especially with the relatively r...
