Curvature refers to how much a geometric object deviates from being flat or straight. The curvature of a curve at a point is defined as the rate of change of the tangent vector as you move along the curve. For a plane curve given by the equation y=f(x), the curvature K is defined by the formula K = |f''(x)| / [1 + (f'(x))^2]^(3/2), where f'(x) is the first derivative and f''(x) is the second derivative.

Living cells are constantly exposed to various signals from their surroundings.
These signals can be:
Chemical: Such as hormones, pathogen signals, mating signals, and ozone.
Physical: Such as changes in light, temperature, and pressure.
To respond appropriately to these signals, cells have special proteins called receptors on their surface. These receptors detect the signals and convert them into internal messages that the cell can understand and act upon.
How Signals are Processed?
1. Signal Detection: receptors on the cell surface.
2. Transduction:
The receptor activates proteins inside the cell, which then produce molecules called "second messengers."
3. Signal Amplification and Cascades:
These second messengers amplify the signal and pass it on to other proteins, triggering a cascade of reactions.
4. Response:
The cascades can lead to changes in gene expression, enzyme activity, or cell behavior, ultimately leading to a physiological response.
What are Phospholipids?
Structure:
Phospholipids are a type of lipid molecule that are a major component of all cell membranes.
They consist of two fatty acid tails that are hydrophobic (repel water) and a phosphate head that is hydrophilic (attracts water).
This unique structure allows them to form bilayers, creating the fundamental structure of cell membranes.
Where are Phospholipids Found in Plants?
Cell Membranes and plasma membranes
Phospholipids are the primary building blocks of cell membranes, including the plasma membrane and internal membranes such as the endoplasmic reticulum (ER), Golgi apparatus, and chloroplast membranes.

Pig farming, pork farming, pig production or hog farming is the raising and breeding of domestic pigs as livestock, and is a branch of animal husbandry. Pigs are farmed principally for food (e.g. pork: bacon, ham, gammon) and skins.
Pigs are amenable to many different styles of farming: intensive commercial units, commercial free range enterprises, or extensive farming (being allowed to wander around a village, town or city, or tethered in a simple shelter or kept in a pen outside the owner's house). Historically, farm pigs were kept in small numbers and were closely associated with the residence of the owner, or in the same village or town.[1] They were valued as a source of meat and fat, and for their ability to convert inedible food into meat and manure, and were often fed household food waste when kept on a homestead.[2] Pigs have been farmed to dispose of municipal garbage on a large scale.[3]
All these forms of pig farm are in use today, though intensive farms are by far the most popular, due to their potential to raise a large amount of pigs in a very cost-efficient manner.[4] In developed nations, commercial farms house thousands of pigs in climate-controlled buildings.[5] Pigs are a popular form of livestock, with more than one billion pigs butchered each year worldwide, 100 million in the United States. The majority of pigs are used for human food, but also supply skin, fat and other materials for use in clothing, ingredients for processed foods,[6] cosmetics,[7] and medical use.[8]Pig farming has gained importance today. Pigs have inherited capacity to acclimatize with varying climatic conditions. Pigs cannot withstand high temperature climate.
Pigs are adjusted to varied rearing practices and consume different types of food (Omnivorous) to attain higher growth and meat production.
Pigs will attain 60-70kg body weight in 6-8months period.
Female pigs i.e., sows will come to heat at age of 8-9 months but avoid using male pigs (Boars) for breeding purpose until it attains one year of age.
Adult sows when bred during right time after attaining maturity will farrow 8-12 piglets in 112-118 days of gestation period (i.e., about 4 months of gestation). Feedefficiencyis to gain one Kg live weightfor every 2.75-3kg feed consumed (FCR: 1:2.75). There are many advantageous in pig rearing. Pork is available at a cheaper price with nutritious and highly palatable tasty meat of higher quality animal protein. Pig bones are used for producing bone meal and also used for purification of sugar in sugar industry.
The manure droppings and urine are good fertilizers which enhance the soil fertilityand improve grain production.
Pig hairs (Bristles) are used for making brushes and ropes, hooves are used for shirt button making and preparation of gum. Hence, pigs are called as multi utility domestic animals. Farmers can take up piggery farming and reduce their debt burden and improve their profits and livelihood.

Dynamically studying trans-Neptunian object (TNO) binaries allows us to measure masses and orbits. Most of the known objects appear to have only two components, except (47171) Lempo, which is the single known hierarchical triple system with three similar-mass components. Though hundreds of TNOs have been imaged with high-resolution telescopes, no other hierarchical triples (or trinaries) have been found among solar system small bodies, even though they are predicted in planetesimal formation models such as gravitational collapse after the streaming instability. By going beyond the point-mass assumption and modeling TNO orbits as non-Keplerian, we open a new window into the shapes and spins of the components, including the possible presence of unresolved inner binaries. Here we present evidence for a new hierarchical triple, (148780) Altjira (2001 UQ18), based on non-Keplerian dynamical modeling of the two observed components. We incorporate two recent Hubble Space Telescope observations, leading to a 17 yr observational baseline. We present a new open-source Bayesian pointspread function fitting code called nPSF that provides precise relative astrometry and uncertainties for single images. Our non-Keplerian analysis measures a statistically significant (2.5) nonspherical shape for Altjira. The measured J2 is best explained as an unresolved inner binary, and an example hierarchical triple model gives the best fit to the observed astrometry. Using an updated non-Keplerian ephemeris (which is significantly different from the Keplerian predictions), we show that the predicted mutual event season for Altjira has already begun, with several excellent opportunities for observations through 2030.Units and measurements includes definition and fundamental quantities.pptx

This presentation offers a bird's eye view of autosomes and sex chromosomes. It also explores the different kinds of diseases of humans due to autosomal and sex-linked inherited traits. The sex determination of plants has been explained. The ratio of sex in the human population along with cause and consequences has been explained here.Drug evaluation Organoleptic, Microscopic, Chemical, Biological
