Achilles

Stereochemistry refers to chemistry in three dimensions Its foundations were laid by Jacobus van t Hoff and Joseph Achille Le Bel m 1874 Van t Hoff and Le Bel mde pendently proposed that the four bonds to carbon were directed toward the corners of a tetrahedron One consequence of a tetrahedral arrangement of bonds to carbon is that two compounds may be different because the arrangement of their atoms m space IS different Isomers that have the same constitution but differ m the spatial arrangement of their atoms are called stereoisomers We have already had considerable experience with certain types of stereoisomers—those involving cis and trans substitution patterns m alkenes and m cycloalkanes... 

Removing decay heat has been the "Achilles Heel" of nuclear power. The designs shown in this section use active methods to remove the heat, (a) Sketch and discuss a design that removes the heat passively, (b) It would seem that the energy in the decay heat could be used for its own removal. Sketch and discuss a design that uses this property to remove the decay heat. 

Joseph Achille Le Bel (IB47-1930I was born in Pechelbronn, France, and studied at the Ecole Polytechnique and the Sorbonne in Paris. Freed by his family s wealth from the need to earn a living, he established his own private laboratory.

Tendinitis is an inflammatory painful tendon disorder which can be caused by quinolones. Typical cases are characterized by acute onset, palpation and sharp pain mostly of one or both Achilles tendons, but other tendons may also be affected. Magnetic resonance imaging (MRI) is used to support the diagnosis. Estimates for the incidence of quinolone-induced tendinitis range from approximately 1 100 to 1 10,000. The etiology remains unknown, concomitant... 

All fluoroquinolone drugs can cause pain, inflammation, or rupture of a tendon. The Achilles tendon is particularly vulnerable. This problem can be so severe tiiat prolonged disability results, and, at times, surgical intervention may be necessary to correct die problem, hi addition, the fluoroquinolone drugs, particularly sparfloxacin and lomefloxacin, cause dangerous photosensitivity reactions. Fhtients have experienced severe reactions even when sunscreens or sunblocks were used. 

EDMD is another X-linked muscular dystrophy, clinically and genetically completely distinct from DMD and BMD. Affected boys usually have onset in childhood of contractures (especially involving the Achilles tendons, elbows, and spinal muscles), humeroperoneal muscle weakness, and cardiac conduction defects, which tend to be mostly a problem in adult life and may necessitate insertion of a pacemaker. The gene for EDMD is known to map to Xq28, but this localization is...

The weak spots, or Achilles heels, of the body occur where the skin ends and mucous epithelial tissues begin (mouth, anus, eyes, ears, nose and urinogenital tract). These mucous membranes present a much more favourable environment for microbial growth than the skin, in that they are warm, moist and rich in nutrients. Such membranes. 

The Achilles heel of two-dimensional TLC is the difficulty recording and quantifying chromatograms. 

Patients with genetic disorders that cause a marked increase in serum LDL cholesterol (greater than 250 mg/dL [6.48 mmol/L]) may present with corneal arcus of the eye and xanthomas of extensor tendons of the hand and Achilles tendon.

In ICP-AES and ICP-MS, sample mineralisation is the Achilles heel. Sample introduction systems for ICP-AES are numerous gas-phase introduction, pneumatic nebulisation (PN), direct-injection nebulisation (DIN), thermal spray, ultrasonic nebulisation (USN), electrothermal vaporisation (ETV) (furnace, cup, filament), hydride generation, electroerosion, laser ablation and direct sample insertion. Atomisation is an essential process in many fields where a dispersion of liquid particles in a gas is required. Pneumatic nebulisation is most commonly used in conjunction with a spray chamber that serves as a droplet separator, allowing droplets with average diameters of typically <10 xm to pass and enter the ICP. Spray chambers, which reduce solvent load and deal with coarse aerosols, should be as small as possible (micro-nebulisation [177]). Direct injection in the plasma torch is feasible [178]. Ultrasonic atomisers are designed to specifically operate from a vibrational energy source [179].
