Comparative analysis of the fit of 3-unit implant-supported frameworks cast in nickel-chromium and cobalt-chromium alloys and commercially pure titanium after casting, laser welding, and simulated porcelain firings

This study compared the vertical misfit of 3-unit implant-supported nickel-chromium (Ni-Cr) and cobalt-chromium (Co-Cr) alloy and commercially pure titanium (cpTi) frameworks after casting as 1 piece, after sectioning and laser welding, and after simulated porcelain firings. The results on the tightened side showed no statistically significant differences. On the opposite side, statistically significant differences were found for Co-Cr alloy (118.64 mu m [SD: 91.48] to 39.90 mu m [SD: 27.13]) and cpTi (118.56 mu m [51.35] to 27.87 mu m [12.71]) when comparing 1-piece to laser-welded frameworks. With both sides tightened, only Co-Cr alloy showed statistically significant differences after laser welding. Ni-Cr alloy showed the lowest misfit values, though the differences were not statistically significantly different. Simulated porcelain firings revealed no significant differences.

AssiDomän Frövi board mill has in cooperation with students from Graphic Technologyat the University of Dalarna a degree project that involves developing package solutionsin carton material from AssiDomän Frövi. This year the basic condition was to use theweights 270g/m2, 300g/m2 and 330g/m2 and choose between Frövi Bright, Frövi Lightand Frövi Carry.The packages were supposed to be in the segments industrial products,chocolate/sweets and beauty products/cosmetics. Two packages were produced in thesegments industrial products and beauty products/cosmetics.The first package, produced in the industrial segment, contains textile color and templatesand the second package is a gift package and contains nail polish.The investigation part of the project deals with how the packages today are fit forrheumatics in opening purpose.

Leader-organization fit: comparing the effectiveness of paternalistic and transformational leadership in different organizational cultures

Research on paternalistic leadership (PL) has been based exclusively on national cultures´ differences. However there are cues that other contextual variables can add to the explanation of this construct. Due to its capacity to influence expectations of individuals in organizations, organizational culture can contribute to fill this gap. To test if organizational culture influences the effectiveness of leadership style, we conducted two experimental studies using Amazon’s Mechanical Turk, comparing effects of paternalistic and transformational leadership on followers’ outcomes. Using video clips and vignettes, we found that PL is better related to followers´ outcomes in cultures oriented to people than outcome, and that TL has a better relationship in cultures oriented to innovation than stability. The results suggest that organizational culture helps in explaining PL endorsement, and that further analysis of the influence of this variable to PL can provide a better understanding of the expression of this leadership style in organizations.

On paternalistic leadership fit: exploring cross-cultural endorsement, leader-follower fit, and the boundary role of organizational culture

Although cross-cultural leadership research has thrived in international business literature, little attention has been devoted to understanding the effectiveness of non-western theories beyond their original contexts. The purpose of this study is to examine the cross-cultural endorsement of paternalistic leadership, an emerging non-western leadership theory, using data from GLOBE project. Using multigroup confirmatory factor analyses we found measurement equivalence of a scale derived from GLOBE’s data, which enabled us to compare the endorsement of paternalistic leadership dimensions across 10 cultural clusters and 55 societies. Our study revealed that there are significant differences in the importance societies give to each dimension, suggesting that paternalism as leadership style is not universally nor homogeneously endorsed. Furthermore, results suggest that different patterns of endorsement of each of these dimensions give rise to idiosyncratic shades of paternalistic leadership across societies. Implications for theory and future research on international business are discussed.

Effect of Passive Fit Absence in the Prosthesis/Implant/Retaining Screw System: A Two-Dimensional Finite Element Analysis

The misfit between prostheses and implants is a clinical reality, but the level that can be accepted without causing mechanical or biologic problem is not well defined. This study investigates the effect of different levels of unilateral angular misfit prostheses in the prosthesis/implant/retaining screw system and in the surrounding bone using finite element analysis. Four models of a two-dimensional finite element were constructed: group I (control), prosthesis that fit the implant; groups 2 to 4, prostheses with unilateral angular misfit of 50, 100, and 200 mu m, respectively. A load of 133 N was applied with a 30-degree angulation and off-axis at 2 mm from the long axis of the implant at the opposite direction of misfit on the models. Taking into account the increase of the angular misfit, the stress maps showed a gradual increase of prosthesis stress and uniform stress in the implant and trabecular bone. Concerning the displacement, an inclination of the system due to loading and misfit was observed. The decrease of the unilateral contact between prosthesis and implant leads to the displacement of the entire system, and distribution and magnitude alterations of the stress also occurred.

Análise do equilíbrio em pacientes hemiparéticos após o treino com o programa Wii Fit

OBJETIVO: A hemiparesia é um comprometimento parcial do hemicorpo que altera o equilíbrio, sendo este essencial para as atividades funcionais. OBJETIVO: Avaliar o equilíbrio em pacientes hemiparéticos submetidos ao treino de equilíbrio com o programa Wii Fit, que atuou como um recurso de biofeedback visual. MÉTODO: Foram selecionados 12 pacientes hemiparéticos pós AVE, 5 do sexo masculino e 7 do sexo feminino, com idade média de 58 ± 12,57 anos, divididos aleatoriamente em dois grupos. Um deles realizou a fisioterapia convencional (GC) pelo período de uma hora, o outro realizou por trinta minutos e mais trinta minutos de treino de equilíbrio com auxílio do Wii Fit (GW), duas vezes por semana durante cinco semanas, completando dez sessões. O equilíbrio foi avaliado antes e após as intervenções, por meio da aplicação da Escala de Equilíbrio de Berg (EEB) e pela estabilometria, que mensura a oscilação do centro de pressão (COP), nos eixos ântero-posterior (AP) e médio-lateral (ML), por uma plataforma de pressão em duas condições: de olhos abertos (OA) e olhos fechados (OF). RESULTADOS: de acordo com a EEB, os pacientes, tanto do GC quanto o do GW, obtiveram maior controle do equilíbrio estático e dinâmico. Na avaliação do COP no eixo ML, os indivíduos do GC e do GW tiveram diminuição na oscilação ML após a intervenção proposta para cada grupo, nas condições de OA e OF. No eixo AP do COP, o GC não teve diminuição na oscilação AP de OA e OF, e o GW apresentou diminuição na oscilação AP de OA e OF. CONLUSÃO: O presente estudo demonstra que a fisioterapia associada ao treino de equilíbrio com o Wii Fit apresenta resultados significantes na reabilitação dos indivíduos hemiparéticos, obtendo, assim, mais um recurso terapêutico na fisioterapia.
