Finger cracks

Tiated and untinted soft Hpstick masses are distributed ia pans as Hp glosses. These are appHed with the fingers or with Hpstick bmshes. Hard, tinted, pencil-type sticks have been marketed as Hp liners. Chap sticks are unpigmented Hpsticks iatended to alleviate scaling and to prevent cracked Hps. Compositions of Hpsticks, Hp glosses, and chap sticks have been pubHshed (90).

It is unlikely that a leak could develop on a glass tube that has not received stress or that has not been worked on by a glassblower. Therefore to save time, simply pass the Tesla coil around areas where glass sections have been joined (see Fig. 7.58). If there is a two- or three-fingered clamp in an area that needs to be tested, the clamp must be removed to properly check the seal. To spark check for cracks around hooks placed near a joint, place a rubber stopper in the end of the joint and then open up the stopcock to evacuate that section. 

An exception to this rule would be if a two- or three-fingered support clamp was overly tightened on a glass tube, causing the tube s wall to crack. 

Soon this boy added chemistry to hie list of hobbies. Through his father he met a friend who had a rich library and a private chemical laboratory where he obtained permission to work. He built voltaic piles out of zinc plates and some old Russian copper coins he had collected. The master of the German mint presented him with an old furnace in which, with the aid of his sister to blow the bellows, he would build a roaring fire. And while he experimented he burned his fingers with phosphorus, and on another occasion was almost killed when a flask containing poisonous chlorine cracked in his hands. 

A healthy 36-year-old man, who had used intranasal crack cocaine daily in increasing doses for 2 weeks, developed pain, numbness, swelling, and cyanosis of the fingers and toes aggravated by cold and an ulcer on one finger (91). Ultrasound Doppler of the hand confirmed ischemic finger necrosis. He was treated unsuccessfully with aspirin, diltiazem, and heparin, but responded to intravenous infusions of iloprost for 5 days. 

Rg. 18. Localized finger-shaped epsilon CTPZ development in PEC. The DCO crack arrest bands are not visible in this optical micrograph. The irregular lines at the top of the Cmger-Ukc regions arc due to moisture in the cracks. A faint com x craze profile can be seen at the extreme tips ...
