Como objetivo co-lateral, os filmes dopados depositados sobre plastico foram usados como sensores de deformacao, utilizando as suas propriedades piezo-resistivas. A influencia de diferentes parametros de deposicao sobre as propriedades e taxa de deposicao dos filmes resultantes foram estudados e correlacionados. Celulas solares de filmes finos de silicio amorfo e microcristalino foram desenvolvidas a baixas temperaturas sobre plasticos.
Eficiencias de 5 - 6. Efeitos de aprisionamento da luz foram estudados atraves da texturizacao por ablacao laser de substratos de plastico e corrosao umida de TCO sobre plastico.
Estruturas de teste em textil e a miniaturizacao dos sensores piezoresistivos depositados sobre substratos flexiveis de poliimida foram abordados. Pain, described as facial pain, headache or earache, usually exacerbated by jaw use, is generally the patients' main complaint. Laser photobiomodulation has been used for treating pain in cases of TMD. Voz sobre frame relay.

Algunos apuntes sobre comunidad. This aspect, which is not properly evaluated by residents, is very important for health professionals to do our work of promotion, prevention and treatment not only at the level of the individual, but also at the level of the family and of the community as a whole. Therefore, we need to have some notions about community and community participation to be able to promote them, as the only way to make our health actions more effective.
The random skin flap measured 10 x 4 cm and a plastic sheet was interposed between the flap and donor site. Group 1 control underwent sham irradiation with diode laser nm. Group 2 was submitted to laser irradiation with diode laser nm. The probe was usually held in contact with the skin flap surface on a point at 2. On the seventh postoperative day, the percentage of necrotic area was measured and calculated.

Lasers technology. Laser applications and research occur within several areas such as Nuclear, Medicine, Dentistry, Industry, Environment and Advanced Research. Additional goals of the Program are human resource development and innovation, in association with Brazilian Universities and commercial partners. Characterization of the surface oxidation reaction and its influence on the radiation absorption during the surface laser hardening process of the 42CrMo4 steel; Caracterizacion de la reaccion de oxidacion superficial y su influencia sobre la absorcion de radiacion durante el proceso de temple superficial con laser para el acero 42CrMo4.
Surface laser hardening of steel is a process that produces an enormous interest due to its uncountable advantages in terms of quality and productivity against induction hardening The effective implantation of this process, nevertheless, is been hampered because of the lack of reliable and flexible predictive tools. There are different models focused on the temperature calculation, thought, few make a thorough analysis of the surface oxidation associated with the process and its important implications over the absorption coefficient.
These conditions have been reproduced experimentally, tracking the maximum surface temperature and the oxide thickness. Both results have shown a high degree of coincidence whit theoretical predictions, confirming the capabilities and utility of the model. YCOB lasers. Lasers based on this host material will open new opportunities for the development of compact, high-power, frequency-agile visible and near IR laser sources, as well as sources for ultrashort pulses.
Moreover, since these materials are biaxial, and have high nonlinear optical coefficients, they have become the first laser materials available as efficient self-frequency-doubled lasers , capable of providing tunable laser emission in several regions of the visible spectrum. Self-frequency doubling eliminates the need for inclusion of a nonlinear optical element within or external to the laser resonator. These laser materials possess excellent thermal and optical properties, have high laser -damage thresholds, and can be grown to large sizes.
In addition they are non-hygroscopic. They therefore possess all the characteristics necessary for laser materials required in rugged, compact systems.
Here we summarize the rapid progress made in the development of this new class of lasers , and review their potential for a number of applications. Laser sampling. The review is devoted to the major advances in laser sampling. The advantages and drawbacks of the technique are considered. Specific features of combinations of laser sampling with various instrumental analytical methods, primarily inductively coupled plasma mass spectrometry, are discussed. Examples of practical implementation of hybrid methods involving laser sampling as well as corresponding analytical characteristics are presented.
The bibliography includes 78 references. HF laser. A review is made of the research and development of HF chemical laser and its related work. Many gaseous compounds are used as laser media successfully; reaction kinetics and technological problems are described. The hybrid chemical laser of HF-CO 2 system and the topics related to the isotope separation are also included.

Laser fusion. In this paper, the physics of laser fusion is described on an elementary level. The irradiated matter consists of a dense inner core surrounded by a less dense plasma corona. The laser radiation is mainly absorbed in the outer periphery of the plasma. The absorbed energy is transported inward to the ablation surface where plasma flow is created. Due to this plasma flow, a sequence of inward going shock waves and heat waves are created, resulting in the compression and heating of the core to high density and temperature.
The wavelength scaling of the physical processes is also discussed. In addition to the laser -plasma physics, the Nd high power pulsed laser is described. We give a very brief description of the oscillator, the amplifiers, the spatial filters, the isolators and the diagnostics involved. Last, but not least, the concept of reactors for laser fusion and the necessary laser system are discussed.

Biocavity Lasers. Laser technology has advanced dramatically and is an integral part of today's healthcare delivery system. Lasers are used in the laboratory analysis of human blood samples and serve as surgical tools that kill, burn or cut tissue. Recent semiconductor microtechnology has reduced the size o f a laser to the size of a biological cell or even a virus particle.
By integrating these ultra small lasers with biological systems, it is possible to create micro-electrical mechanical systems that may revolutionize health care delivery. Laser Dyes. VIS, and near IR region. It is used as reference dye For instance Laser spectroscopy.
