Until the present date, historians of science have described inaccurately the first laboratory created in Brazil for establishing and divulging Chemistry, namely the "Laboratório Químico-Prático do Rio de Janeiro". During recent research carried out in the Arquivo do Museu Imperial (Petrópolis, RJ), I localized a document entitled "Ensaio histórico analítico das operações do Laboratório Químico-Prático do Rio de Janeiro", which allowed me to gain the relevant information to correct some of the observations made in the first chronicles.

The use of 12-year-old Pinus tecunumanii (Eguiluz e Perry) grown in Colombia was evaluated for bleached kraft pulp production. Kraft pulps of kappa number 30 ± 1 were produced, and oxygen delignified and bleached to 90% ISO with ECF processes. The bleached pulps produced under optimum conditions were evaluated with regard to their strength properties. Pinus tecunumanii wood required low effective alkali charge to reach the desired kappa number and the unbleached pulp showed high oxygen delignification efficiency and bleachability when a OD(EO)DED sequence was used. The bleached pulps presented good physical-mechanical properties, which are comparable to those obtained with more traditional pines such as Pinus taeda and Pinus radiata. The results demonstrate that this tropical pine species is a suitable raw material for bleached kraft pulp production

O objetivo deste estudo foi avaliar, através da análise espacial de dados geográficos, a precisão de procedimentos de mapeamento das populações de cigarras (Quesada gigas Oliver) em povoamentos de paricá (Schizolobium amazonicum Huber ex Ducke), localizados no Município de Dom Eliseu, PA, mediante a aplicação de dois interpoladores (krigagem e inverso do quadrado da distância). Para tal, foram registradas amostras na intensidade de um ponto a cada 30 ha, onde se realizou a contagem do número de cigarras por planta (cigarras/árvore), obedecendo à estratégia de amostragem convencionalmente usada pela empresa proprietária do reflorestamento em estudo. As análises indicaram que a intensidade amostral empregada neste trabalho não foi suficiente para permitir a detecção de forte dependência espacial do número de cigarras/árvore nas áreas estudadas. Devido a essa baixa dependência espacial, os resultados dos dois métodos de interpolação (krigagem ordinária e inverso do quadrado da distância) apresentaram-se semelhantes. Já os deste trabalho indicaram que as estratégias de amostragem utilizadas devem ser melhoradas para gerar mapas de predição mais precisos da quantidade de cigarras/árvore nos reflorestamentos de paricá.

The objective of this research was to describe how Nordic companies manage hazard risks in their operations in Russia and how the local business environment is considered to affect the hazard risks. Research methods used in this research were literature review and expert interviews. Twelve Nordic industrial companies operating in different fields of industry were interviewed. Large Nordic companies typically guide risk management centralized from the parent company on behalf of the whole company group and the risk management standards and policies are integrated in all subsidiaries. Parent companies typically control hazard risk management in Russia by regular risk management reporting, auditing the Russian sites and by training local managers and employees to risk management work. Many companies have experienced several losses in the first years of operating in Russia before the risk management policies have been implemented in Russian subsidiaries. The companies have learned to take local characteristics better into account by experience and most companies are quite satisfied with their current risk management standards in Russia. The interviews indicate that companies experience especially the poor quality of infrastructure, some features in Russian organizational culture and high level of criminality to increase hazard risks in Russia. However, understanding these features and risks in the business environment makes the management of these risks possible. Risks related to infrastructure can be managed in advance by decreasing dependencies of infrastructure and considering the infrastructure quality already when planning the business operations. Also good local network is often considered critical in order to overcome the complications related to infrastructure. Russian personnel has typically different attitude towards risk management than Nordic personnel and neglecting safety and maintenance and concealing losses is more typical in Russia. By training and guiding the local personnel risk management and safety work and desired ways of actions these risks can be decreased. Criminality risks are often managed to certain extent by investing in security, increasing supervising and paying attention to reliability of the employees and other interest groups of the company.

Homoplasmy is a feature usually found in the mtDNA of higher animal taxa. On the other hand, the presence of two classes of mtDNA in the same cell or organism is rare and may appear in length or site variation. Data from mtDNA RFLP analysis of Brycon opalinus populations (Cuvier, 1819; Characiformes, Characidae, Bryconinae) revealed site heteroplasmy from endonuclease NheI digestion. Southern blotting hybridization was used to survey a total of 257 specimens with 24 restriction enzymes. Three different restriction fragment patterns of mtDNA were obtained from NheI digestion. Two individuals from hatchery broodstock were found to have two of them. NheI digests of heteroplasmic individuals yielded two fragments of approximately 1180 and 1260 bp. Despite the low frequency of this type of heteroplasmy in the whole B. opalinus population, the presence of site heteroplasmy in this species supports the evidence of this phenomenon in lower vertebrate groups.
