Winter Care

Winter Skin Care

 For many people, the cold clear days of winter bring more than just a rosy glow to the cheeks. They also bring uncomfortable dryness to the skin of the face, hands, and feet. For some people, the problem is worse than just a general tight, dry feeling: They get skin so dry it results in flaking, cracking,


1. Seek a Specialist

If you go to your local drugstore, you'll be hard put to find a salesperson who can give you good advice. That's why going to an esthetician or dermatologist even once is a good investment. Such a specialist can analyze your skin type, troubleshoot your current skin care regimen, and give you advice on the skin care products you should be using.



2. Moisturize More

You may have found a moisturizer that works just fine in spring and summer.  But as weather conditions change, so, too, should your skin care routine.  Find an "ointment" moisturizer that's oil-based, rather than water-based, as the oil will create a protective layer on the skin that retains more moisture than a cream or lotion.

Nanorotics



NANOROBOTICS


Nanorobotics is the emerging technology field creating machines or robots whose components are at or close to the scale of a nanometre (10−9 meters). More specifically, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or molecular components.The names nanobots, nanoids, nanites, nanomachines or nanomites have also been used to describe these devices currently under research and development.
nanorobot
Nanomachines are largely in the research-and-development phase, but some primitive molecular machines have been tested. An example is a sensor having a switch approximately 1.5 nanometres across, capable of counting specific molecules in a chemical sample. The first useful applications of nanomachines might be in medical technology, which could be used to identify and destroy cancer cells. Another potential application is the detection of toxic chemicals, and the measurement of their concentrations, in the environment. Rice University has demonstrated a single-molecule car developed by a chemical process and including buckyballs for wheels. It is actuated by controlling the environmental temperature and by positioning a scanning tunnelling microscope tip.
Another definition is a robot that allows precision interactions with nanoscale objects, or can manipulate with nanoscale resolution. Such devices are more related to Microscopy or Scanning probe microscopy, instead of the description of nanorobots as molecular machine. Following the microscopy definition even a large apparatus such as an atomic force microscope can be considered a nanorobotic instrument when configured to perform nanomanipulation. For this perspective, macroscale robots or microrobots that can move with nanoscale precision can also be considered nanorobots.

Christmas Celebration

ON THE EVE OF CHRISTMAS



Christmas is an annual commemoration of the birth of Jesus Christ and a widely observed holiday, celebrated generally on December 25 by millions of people around the world.A feast central to the Christian liturgical year, it closes the Advent season and initiates the twelve days of Christmastide. Christmas is a civil holiday in many of the world's nations,is celebrated by an increasing number of non-Christians, and is an integral part of the Christmas and holiday season.

 The precise year of Jesus' birth, which some historians place between 7 and 2 BC, is unknown. His birth is mentioned in two of the four canonical gospels. By the early-to-mid 4th century, the Western Christian Church had placed Christmas on December 25, a date later adopted in the East. The date of Christmas may have initially been chosen to correspond with the day exactly nine months after early Christians believed Jesus to have been conceived,as well as the date of celebration of the southern solstice , with a sun connection being possible because Christians consider Jesus to be the "Sun of righteousness" prophesied in Malachi.

 Christmas is both a sacred religious holiday and a worldwide cultural and commercial phenomenon. For two million, people around the world have been observing it with traditions and practices that are both religious and secular in nature. Christians celebrate Christmas Day as the anniversary of the birth of Jesus of Nazareth, a spiritual leader whose teachings form the basis of their religion. Popular customs include exchanging gifts, decorating Christmas trees, attending church, sharing meals with family and friends and, of course, waiting for Santa Claus to arrive. December 25–Christmas Day–has been a federal holiday in the United States since 1870.

SANTA CLAUS

Santa Claus, also known as Saint Nicholas, Father Christmas and simply "Santa", is a figure with legendary, mythical, historical and folkloric origins who, in many western cultures, is said to bring gifts to the homes of the good children during the late evening and overnight hours of Christmas Eve, December 24. During the Christianization of Germanic Europe, this figure may have absorbed elements of the god Odin, who was associated with the pre-Christian midwinter event of Yule and led the Wild Hunt, a ghostly procession through the sky. The modern figure of Santa Claus was derived from the Dutch figure of Sinterklaas, which, in turn, was part of its basis in hagiographical tales concerning the historical figure of Christian bishop and gift giver Saint Nicholas.

Santa Claus
 Santa Claus is generally depicted as a portly, joyous, white-bearded man—sometimes with spectacles—wearing a red coat with white collar and cuffs, white-cuffed red trousers, and black leather belt and boots (images of him rarely have a beard with no moustache). This image became popular in the United States and Canada in the 19th century due to the significant influence of Clement Clarke Moore's 1823 poem "A Visit From St. Nicholas" and of caricaturist and political cartoonist Thomas Nast.This image has been maintained and reinforced through song, radio, television, children's books and films.
