The article examines the consequences of corruption, political stability and state institutions on foreign direct investments in Romania as a result of the development of financial instruments and technological means. The paper examines the concepts found in the literature referring to the impact of corruptions on foreign direct investment and the power of the authorities to maintain the quality of their governance through the degree of economic liberalization. In this study, statistical data on corruption, foreign direct investments and governmental efficiency have been interpreted. The purpose of writing this article was to present the effects of corruption on foreign direct investments in Romania in order to generate new information on this topic that is not developed in the literature.

This review article discusses the current and future possibilities for the application of in situ transmission electron microscopy to reveal synthesis pathways and functional mechanisms in complex and nanoscale materials. The findings of a group of scientists, representing academia, government labs and private sector entities (predominantly commercial vendors) during a workshop, held at the Center for Nanoscale Science and Technology- National Institute of Science and Technology (CNST-NIST), are discussed. We provide a comprehensive review of the scientific needs and future instrument and technique developments required to meet them.

Aim. The assessment of distribution of supernumerary permanent teeth (SPT) and the disturbances caused by them. Material and method. Cross-sectional study upon a sample of 85 children (58 boys) aged between 3 and 18 years (mean age=9.08±3.09 years) with at least one SPT. Were analyzed: patients' distribution according to gender, age and number of dental units; SPT distribution according to arch and topography and also the disturbances noticed. Results. a) boys:girls ratio=2.14:1; b) the 85 patients had 107 SPT, mean number=1.25; c) 76.47% of patients had one SPT; d) 89.72% of SPT were on maxillary arch, maxilla:mandible ratio = 8.7:1; d) 92.52% of SPT were localized in anterior region, anterior:posterior region ratio = 12.3:1; e) mesiodens –71.96%, supernumerary lateral incisor – 19.62%; f) disturbances caused by SPT: ectopic eruption of permanent teeth – 36.47%; delay or failure of eruption of permanent teeth – 21.17%; crowding – 20%. Conclusions. 1. Supernumerary teeth were most frequent noticed in boys, in maxillary anterior region. 2. Most often they caused eruption disturbances of permanent teeth. Keywords: supernumerary permanent teeth, distribution, complications.
