Although they are pegged to receive, emergencies occur with some frequency and sometimes cannot be "predicted" or even when emergency situations occur they become crucial and can save an organization from a harmful disbursement. However, most urgent purchases are oriented toward the low or inexistent planning, which, in addition to the economic factor in increasing the value of the good or the service, affects the areas involved, and even the image of the organization, the environmental and safety factors. Thus, the cause of emergencies becomes an indication and the negotiations can mean reduction of millions in expenses of large industries. Thus, the study became systemic in the emergency purchases of a large Brazilian pulp and paper producer, in addition, a methodology that allowed the reduction of planting and application costs. As a result, the goal of a 10% reduction in emerging expenditures in 2018 when compared to the previous year. [ABSTRACT FROM AUTHOR]

The objective of this study was to evaluate properties of brown pulp from Eucalyptus grandis and Eucalyptus urograndis of distinct chemical composition, mainly in refers to its xylans content, for the manufacture of tissue and printing and writing (P&W) paper grades. Brow pulps of kappa number 17-18 and xylans contents varying 6-21% had been produced under different cooking protocols: 1) conventional kraft; 2) pre-hydrolysis kraft; 3) high alkalinity kraft; and 4) kraft of high yield. The brown pulps had been beated in PFI mill and its respective produced papers had been evaluated as regards physical-mechanical and optic properties. The highest bulk values had been gotten for papers with low xylans contents, what had revealed interesting, if bleached, in the manufacture of tissue papers. The papers with high xylans contents, had been presented technically viable and with resistance characteristics adjusted for the manufacture of P&W papers. [ABSTRACT FROM AUTHOR]

This paper aims to summarize the characteristics of 212 papers and 4 Themes (topics) in two BRASILIAN SYMPOSIA OF GEOGRAPHIC CLIMATOLOGY (2010 and 2012), read and separated according to the explained content and data of each main author, aiming to stimulate studies applied to the North of Brazil. The theoretical framework was based on the literature method and the approach of the study was the quantitative type, with drafting tables that enriched the analysis and interpretation. The researches for this article were based on bibliography search methods. The study demonstrated a decrease in the number of articles published from one event to another and that the scientific production in the Northern region is smaller than in other Brazil's regions, showing a potential for further research concerning this topic.
