Dr. Marder Scalp Therapy for Total Relief from Scalp Itching Winter weather‚ and the subsequent use of indoor heat to stay warm‚ often dries the skin. For those who already suffer from sensitive scalps‚ this can result in dry‚ itchy skin on the scalp. Whether you suffer from extremely dry skin‚ psoriasis‚ or some other scalp condition‚ the itching is enough to drive you crazy. Not to mention all that scratching often loosens dead skin and results in unsightly flaking that can get on your furniture

“I Like to See It Lap the Miles” In “I Like to See It Lap the Miles‚” Emily Dickinson uses metaphoric comparisons of a train to a horse. Dickinson also uses distinctive vocabulary to emphasize objects and places in the poem‚ perhaps to confuse the reader on what the poem is truly about. Although the poem never mentions the words “train” or “horse”‚ Dickinson’s choice of words makes the reader think it is about a train. In the poem Dickinson gives the train characteristics that relateto the

TITLE Vapour Liquid Equilibrium OBJECTIVE To find the Vapour-Liquid Equilibrium (VLE) relationship for binary mixture and to plot the equilibrium curve. INTRODUCTION The term equilibrium is referred to as when a system is in a static condition and there is absolutely no changes that occur as time goes by. Vapour-liquid equilibrium is a condition where a liquid and its vapor are in equilibrium with each other‚ a condition or state where the rate of evaporation is equal to the rate of condensation

Combustible Liquids (Examples: alcohols‚ esters‚ ethers‚ ketones) Vapors from flammable and combustible liquids can mix with air and burn if they contact an ignition source. Possible ignition sources include hot electrical wires‚ hot surfaces‚ open flames‚ hot particles and embers‚ and sparks. The lowest temperature at which a liquid releases enough vapor to start burning is called the flash point. The flash point is what distinguishes a flammable liquid from a combustible liquid. Flammables:

Liquid Chromatography – Laboratory #18 Introduction: We are using liquid chromatography to separate the colored substances in grape-flavored drinks. We separate the component dyes‚ and then we separate the flavorings and citric acids. Background: Chromatography is a process that is used to separate a substance into its component parts. The separation occurs between the stationary and moving phase of the lab. The moving phase consists of a fluid and the stationary phase consists of a solid

In his short story “Victory Lap”‚ George Saunders used characterization to draw attention to how some people find it easier to cover up reality instead of facing it. He first emphasizes on that covering things up habit near the beginning of the story when Alison Pope’s imagination bring her to recreate a situation where a hunter kills a deer. Alison then asks the hunter to‚ “lay her out in a field of clover‚ with roses strewn about her.” With that particular act of putting flowers around the body

Objective:- The aim of this experiment was to find the molar mass of unknown volatile liquid under known temperature and pressure. Introduction Molar mass or gram molar mass is the mass of the substance under consideration without distinguishing whether a substance is an element ‚ a molecule or an ionic compound. These elements‚ molecules or ionic compound could be solid gas or liquid. The molar mass of gas or vapor could be measured if the gases obey the law of Ideal Gas . The mass of
