To percussion

TO, a 77-year-old male nursing home resident is admitted to the hospital with a 3-day history of altered mental status. The patient was unable to give a history or review of systems. On physical examination the vital signs revealed a blood pressure of 100/60 mm Hg, pulse 110 beats per minute, respirations 14/minutes, and a temperature of 101°F (38.3°C). Rales and dullness to percussion were noted at the posterior right base. The cardiac exam was significant for tachycardia. No edema was present. Laboratory studies included sodium 160 mEq/L (160 mmol/L), potassium 4.6 mEq/L (4.6 mmol/L), chloride 120 mEq/L (120 mmol/L), bicarbonate 30 mEq/L (30 mmol/L), glucose 104 mg/dL (5.77 mmol/L), BUN 34 mg/dL (12.14 mmol/L), and creatinine 2.2 mg/dL (194.5 pmol/L). The CBC was within normal limits. Chest x-ray indicated a right lower lobe pneumonia. [Pg.416]

Tetrazene (C2H8N10O) is a pale yellow crystalline explosive generally used in ignition caps, where a small amount is added to the explosive composition to improve its sensitivity to percussion and friction. Tetrazene is not suitable for filling detonators because its compaction properties make the transition from burning to detonation very difficult. This primary explosive is stable in ambient temperatures. Its ignition temperature is lower and it is slightly more sensitive to impact than mercury fulminate. [Pg.52]

Kapsiul Vosplamenitel. Igniter cap, usually referred to as squib. If followed by udarnykh sostavov , it refers to percussion igniters. The formulation used in rifle ( vintovochnyi ) percussion caps is MF 16.7, K chlorate 55.5 Sb trisulfide 27.8% for pistol ( revol vernyi ) percussion caps, MF 25.0, K chlorate 37.5 ... [Pg.539]

An eth sol of Lithium Boroazide, L1B(N,)4 is formed in 90% yield upon evapn to dryness of a reaction mixt consistg of excess HNa in eth soln and frozen L1BH4 in eth soln. The wh solid residue is an expl very sensitive to pressure and to percussion. It is sol in eth and easily hydrolyzed. B(Na)j and LiNa are assumed to be intermediate products (Ref 1)... [Pg.525]

Prepn is by saturating a hot (80°) 10% soln of free 5-Nitrotetrazole with two milliequiv of Pb peroxide. The mixt is stirred rapidly while hot, and on cooling the product crystallizes out. The basic Pb salt is detonated on impact or friction, being more sensitive to percussion than MF because of its brittleness... [Pg.628]

The primer cup contains a mixture of chemicals which sensitize each other to percussion and rapid burning, and consequently the primer burns rapidly producing a flame and a shower of hot particles that penetrates and ignites the propellant. [Pg.10]

Priming compositions for firearms ammunition are mixtures which, when subjected to percussion, provide a sudden burst of flame that serves to ignite the propellant within the cartridge case. A priming composition must deliver a relatively large volume of hot gases and hot solid particles without the development of a detonating wave. [Pg.41]

Pyrophoric alloy primer mixtures never achieved widespread use, presumably because of their lack of sensitivity to percussion.50... [Pg.51]

Accordingly, it was deemed a substance too dangerous to be produced in an ordinary chemical plant. On the other hand, it was also found that its dangerous properties were not easily identified by some commonly practiced test methods an ordinary differential thermal analysis did not give a result suggestive of the danger, and a drop weight sensitivity test of solid 5-CT indicated that the substance was insensitive to percussion. [Pg.39]

Caution. Tetrasulfur tetranitride has been reported to explode when subjected to percussion, friction, sudden heating, or temperatures close to its melting point.912 It should be handled with care and only in relatively small quantities. See Appendix (p. 197) for general safety notes. [Pg.189]

Caution. Isosorbide dinitrate may explode if subjected to percussion or excessive heat. [Pg.691]

Percussion of the spleen is difficult and is carried out by tapping gently at various points on the anterior axillary line. The upper spleen margin lies about 10-15 cm above the left costal arch. The absolute splenic dullness (so-called spleen width) is about 6 to 7 cm it lies between 9 and 11 rib. The splenic width established by percussion corresponds to the anterior lower two thirds of the spleen, i.e. adjacent to the thoracic wall. The upper third of the spleen is covered by the lung. When the spleen is subjected to percussion, variations in the shape of the thorax, diaphragm status and intestinal loops are evident (cf liver percussion). [Pg.79]
