Analytical Fingerprint of Wolframite Ore Concentrates.

Ongoing violent conflicts in Central Africa are fueled by illegal mining and trading of tantalum, tin, and tungsten ores. The credibility of document-based traceability systems can be improved by an analytical fingerprint applied as an independent method to confirm or doubt the documented origin of ore minerals. Wolframite (Fe,Mn)WO is the most important ore mineral for tungsten and is subject to artisanal mining in Central Africa.

Latino Nurses in the United States: An Overview of Three Decades (1980-2010).

Latino Physicians in the United States, 1980-2010: A Thirty-Year Overview From the Censuses.

Purpose: To update and extend a 2000 study on the California Latino physician workforce, the authors examined the Latino physician workforce in the 30-year time frame spanning 1980 to 2010, comparing changes in the rates of physicians per 100,000 population for the Latino and non-Hispanic white (NHW) populations in the United States as a whole and in the five states with (in 2010) the largest Latino populations.

Method: The authors used detailed data from the U.S.

Latino health in California, 1985-1990: implications for family practice.

Family practice, especially when applied to the Community-oriented Primary Care model, needs to incorporate the epidemiological profile and health care needs of a particular community. The rapidly growing Latino population is creating a great number of largely Latino communities. While they tend to have high poverty rates and low education rates, their family and health profiles contradict many assumptions made about poor, underserved minority groups.

[Faults and dangers in treating hand injuries (including tendons and bones) (author's transl)].

Diagnostic procedures include: critical examination of the wound of sensibility, of vascularization, of tendon function, of stability of bones and joints, and examination by roentgen diagnosis. Therapeutic procedures include: the operation, immobilization, active training of noninjured joints, and rehabilitation. Injuries of flexor tendons are treated by the specialist following the method of Kleinert; those of bones and joints can be easily stabilized by Kirschner pins.

[Local traumatic injury of the soft tissue and internal fixation (author's transl)].

The influence of local traumatic injury of the soft tissue on the decision as to whether surgical therapy is indicated and on the method of internal fixation selected for a fresh, closed fracture is discussed. General descriptions of injuries to the soft tissue are followed by a critical discussion of the possibilities of closed and open methods of internal fixation with some examples.
