The experiment was conducted in the experimental area of the University of the State of Mato Grosso/UNEMAT, in Caceres. We evaluated 25 genotypes of saccharin sorghum and 36 genotypes of biomass sorghum, in a randomized complete-block design with three replications. The data were submitted to three clustering methods, Tocher optimization, UPGMA hierarchical and Projection distances in 3D plan and comparing their results. The study showed the most divergent genotypes and the behavior of the three methods, which have proved partially concordant in the grouping of genotypes. The combined use of the clustering methods enabled a more accurate assessment for inference, and evidence the existence of genetic variability among saccharin and biomass sorghum genotypes.

Security-critical infrastructures such as national defenses, public services, and financial services are now exposed to Advanced Persistent Threats (APT) and their resistance to such attacks effects the nations stability. Currently Cyber Threat Intelligence (CTI) is widely used by organizations to mitigate and deter APT for its ability to proactively protect their assets by using evidence-based knowledge. The evidencebased knowledge information can be exchanged among organizations and used by the receiving party to strengthen their cyber security management. This paper will discuss on the business process reengineering of the CTI information exchange management for a nationwide scaled control and governance by the government to better protect their national information security assets.

Given the number of species of the genus found in the region (38 of a total of 98 species), the central region of Brazil was defined as the primary center of cassava diversity. Therefore, genetic diversity characterization of cassava accessions is fundamental, both for farmers and for plant breeders, because it allows the organization of genetic resources and better utilization of available genetic diversity. This research aims to assess genetic divergence of cassava accessions from the south-central region of the State of Mato Grosso, based on multi-categorical morphological traits. For this purpose, 38 qualitative and quantitative morphological descriptors were used. Genetic diversity was expressed by the genetic similarity index, with subsequent clustering of accessions by ...

The two river basins share part of their flora and fauna species and in this ecotone species exchange processes takes place. Therefore it should be considered as an important area to realize the targets for 2020 of the Convention of Biological Diversity (CBD) at the regional level. However, since over 20 years this area is under severe pressure of land conversion and is increasingly threatened by river change, due to building of hydroelectric power stations. This causes direct and indirect damaging effects on the region and on its role as biodiversity corridor. In the framework of the BioNorte project we carried out a Driver, Pressure, State, Impact, Response (DPSIR) analysis of the region and included a stakeholder analysis. The direct pressures are changes in the use of land and rivers that constitute the river ecotone between the Amazon and Pantanal. Indirect pressures are road access, opening the land for further deforestation and agricultural developments. Fragmentation of the remnant forest patches in combination with river fragmentation can cause decline in biodiversity, prevent species exchange between the Amazonia and the Pantanal and fish to spawn upstream. If river flows are being blocked, the flood pulse and the migration corridor of fish and the transport of plant seeds will be hampered. The societal response to this can be denial, a positive reaction by enforcement of traditional conservation actions or, as agreed at the COP 2010 by the Convention of Parties to the CBD as a goal for the year 2020, the integration of biodiversity targets into land development toward sustainable land use by diminishing river and forest fragmentation.

As imagens foram georreferenciadas, classificadas e processadas no software Spring e as classes temáticas, quantificadas e editadas no software ArcGis. Foram mapeadas sete classes, sendo as mais expressivas a vegetação nativa, a pastagem e a cana-de-açúcar. Os resultados indicaram alterações em todas as classes durante os últimos 20 anos, com a diminuição de 22,89% da vegetação nativa, relacionada com o aumento de 58,42% da pastagem e 490,26% de monocultura de cana-de-açúcar. Foi verificado o conflito de uso da terra, principalmente em áreas de mata ciliar, fato que pode influenciar negativamente na conservação da interbacia e, consequentemente, do pantanal mato-grossense.
