Discussion of agglomeration and clustering in the tourist area life cycle (TALC) literature has not led to a corresponding change of the principal equation used to formalize the model. This paper proposes a modification that accounts for the synergies between the accommodation, entertainment, and other components of a tourist destination. The modified model is contrasted with the original TALC ...

-The addition of a 10% talc internal standard to North Pacific sediments allows the relative abundances of clay minerals to be determined both accurately and precisely by X-ray powder diffractometry. Linear programming can be used to generate factors for converting talc-normalized peak areas to weight percentages; hence, absolute clay-mineral abundances can be estimated. This procedure minimize...

UNLABELLED The ideal agent for producing pleurodesis has not been identified. Talc, the most commonly used, poses several problems. Another possibility is silver nitrate, which was widely used in the past. PURPOSE To determine the influence of the intrapleural instillation of lidocaine in producing a pleurodesis with silver nitrate, to define the effect of lidocaine in the maturation of the c...

A 62 yr old woman was initially diagnosed with sarcoidosis until a thoracoscopic biopsy revealed the presence of numerous birefringent particles in fibrotic areas of the centrilobular lung zones. These particles were examined by electron microscopy and X-ray spectrometry and characterized as impure talc. Further inquiry into her occupational history revealed that she had worked from the age of ...

or cerebrospinal fluids have been misidentified as leukocytes by the Coulter method.6,7 Once injected intrapleurally, some of the talc particles will remain in the pleural space for a variable length of time. These residual particles will frequently be mixed with the induced pleural fluid. Investigators should beware that in experimental settings involving the use of talc, total cell counts in ...

BACKGROUND Talc pleurodesis is an effective treatment for malignant pleural effusion. We present a case of an asymptomatic hepatic laceration that occurred during pleurodesis in a breast cancer patient and led to hepatic tumor dissemination. DISCUSSION Pleurodesis is a relatively safe procedure, although previous studies have described malignant invasion of scar tissue. CONCLUSION To our kn...

The s.c. injection of talc, MgSiO3, into mice results in a de crease of hepatic catalase activity. A transient, but marked rise in catalase activity was observed on the 4th day following talc injection. This rise in activity was manifest primarily in the mitochondrial fraction. A concomitant increased incorporation of radioactive leucine occurred in the microsomal fraction. The relationship bet...

BACKGROUND Complicated (recurring or persistent) spontaneous pneumothorax requires treatment either by talc pleurodesis with bullae electrocoagulation or, more aggressively, by thoracotomy or video-assisted thoracoscopic surgery. However, the relative merits of bullectomy, pleurectomy, and pleurodesis have not yet been established in the treatment of spontaneous pneumothorax. METHODS The comp...
