Rancidification
The complete or incomplete oxidation or hydrolysis of fats and oils when exposed to air, light, or moisture or by bacterial action, resulting in unpleasant taste and odor.
Pathways of Rancidification
Three pathways
• Hydrolytic
Hydrolytic rancidity refers to the odor that develops when triglycerides are hydrolyzed and free fatty acids are released. This reaction of lipid with water may require a catalyst, leading to the formation of free fatty acids and glycerol. In particular, short-chain fatty acids, such as butyric acid, are malodorous.
• Oxidative
Oxidative rancidity is associated with the degradation by oxygen in the air. The double bonds of an unsaturated fatty acid can be cleaved by free-radical reactions involving molecular oxygen. This reaction causes the release of malodorous and highly volatile aldehydes and ketones. Because of the nature of free-radical reactions, the reaction is catalyzed by sunlight.
• Microbial
Microbial rancidity refers to a water-dependent process in which microorganisms, such as bacteria or molds, use their enzymes such as lipases to break down fat. By destroying or inhibiting microorganisms, pasteurization (sterilization) and addition of antioxidant ingredients, such as vitamin E, can reduce this process.

Series of events that take place in the genital organs in an effort to expel the viable products of conception out of the womb through the vagina into the outer world is called labor.
Also called “Eutocia”
DELIVERY is expulsion or extraction of a viable fetus out of the womb .
It is not synonymous with labor
Delivery can take place without labor as in elective caesarean section
It may be vaginal, either spontaneous or aided or it may be abdominal
Labor is called normal if it fulfils the following criteria's:
Spontaneous and at term
With vertex presentation
Without undue prolongation
Natural termination with minimal aids
Without having any complications affecting the health of a mother and/or baby
ABNORMAL LABOR
Any deviation from the definition of normal labor is called as abnormal labor
Thus labor in a case with presentation other than vertex or having some complications even with vertex presentation affecting the normal course of labor or modifying the nature of termination or affecting the health of mother or baby is called abnormal labor.
Starvation is defined medically in two parts that is: The act or process of starving and the condition of being starved, while ‘Neglect’ is defined as – to fail to give due care, attention, or time to someone an adult/ a child especially.
Japanese encephalitis_6th batch_NAIHS_Devlop ShresthaDevlop Shrestha
Japanese encephalitis is a mosquito borne encephalitis caused by group B arbovirus
Zoonotic disease
Transmitted by the bite of infected Culex mosquitoes
No man to man transmission of disease
No man to mosquito spread of disease
pathogenesis
Virus enters the body through the bite of mosquitoes
After multiplication in local and regional lymph nodes, viremia of varying duration occurs
Virus is transported to target organ (brain) via blood
Virus proliferate and damages the neuronal tissues , thereby elicits nervous manifestation
The first historic mention of Japanese encephalitis occurred during the
“summer encephalitis” outbreaks in the late 1870s. The next documented
epidemic in Japan occurred in 1924 with 6,125 human cases resulting in
3,797 human deaths (62% case-fatality rate). The virus was first isolated
in Japan in 1935 from a fatal human case of encephalitis. In 1938, the
virus was first isolated from its primary vector species, Culex
tritaeniorhynchus.
In 1940, JE was first identified in China, and in 1949 it was identified in
Korea during a major epidemic that resulted in 5,548 human cases. In
1954 the virus was recognized in India and a major epidemic occurred in
1978 with over 6,000 human cases. In 1983 in South Korea, JE
immunizations started in children as young as age 3 except in endemic
areas where the vaccine was recommended in children even younger.
From 1983 to 1987 the JE vaccine was available in the U.S. on an
investigational basis.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
