GC-MS and LC-MS are science techniques to identify all of the substances that are in a sample. Once identified, they are separated and examined by those in forensics. They both have mobile and stationary bases.GC-MS stands for gas chromatography-mass spectrometry. It is used in samples when molecules are thermally stable. LC-MS stands for liquid chromatography-mass spectrometry. It can be used for both thermal and non-volatile molecules. GC-MS uses gases, while LC-MS uses solvents. Though both are effective, GC-MS is preferred for forensics. Not only is it more reliable, but it is also lower-priced, and it is cheaper to operate.

1. micron-normal non photographic paper is catergorised according to the gsm (grammes per square meter) of the paper stock. for example standard photocopier paper is 80 gsm. the paper used for photobooks through the fujifilm photo creative dpc/phaser combination is 170 gsmphotographic paper is acually catergorised by the thickness & this is measured in microns... all photographic paper is measured in microns. the figures for ca80 are belowgloss 214µmatte 220µlustre 223µanything above 200 microns is greater than gsmmicrons = thickness (thousandth of an inch)gsm = weight (grammes per square metre)

Dorsum of foot including 1st interdigital cleft-common fibular nerve runs posterior to the head of the fibula and wraps around the fibular neck, and so is prone to injury if a fracture occurs at this location. the deep fibular nerve supplies cutaneous innervation to the web of skin between the 1st and 2nd digits (1st interdigital cleft), while the superficial fibular nerve supplies the distal 1/3 of the lateral leg and the rest of the dorsum of the foot; thus, sensory deficits occurs across the entire dorsum of the foot including the web between 1st-2nd toes with a common fibular n. injury since this happened prior to the split into its two terminal branches.

At the bed frame.

Remove the tube and encourage the patient to retain the solution.

Place the infant in a side lying position under a drop light.

Wet cord is a good breeding ground for bacteria.

Absorbance value is inversely related to the solute concentration The energy of a light beam is directly proportional to the wavelength

Left infrasternal angle-the pericardium can be accessed from the anterior thorax through the bare area, so called because the cardiac notch in the left lung (and its pleural covering) leaves part of the pericardium exposed at this location. this is an area where the left lung deflects laterally creating a dull space in the thorax. it is located in the left infrasternal angle, which is between the xiphoid process and costal margin, and can also be accessed through the left 5th and 6th intercostal space immediately to the left of the sternum.
