Abstract Pastures are estimated to cover approximately 47 Mha (24%) of the Brazilian Cerrado with a wide variety of productivity. Political and environmental interest is currently focused on increasing production and reducing carbon emissions, while, while concerns remain about whether this can be done without additional deforestation. We present two future land-use scenarios for the Brazilian Cerrado that take into account expected production volume of soybean and cattle in 2030. Using the Century ecosystem model, we identify where pasture improvement would yield the greatest increase in stocking capacity and distribute the estimated herd for 2030. Likewise, additional soybean production is allocated to areas with agronomic potential and existing infrastructure. We then examine remaining pasture areas for regeneration potential and estimate the effects on soil and biomass carbon stocks under these scenarios. Under modeled biophysical assumptions and assumed rapid adoption, improving ~ 13 Mha of low and medium vigor pasture could allow the estimated herd of 61 MUA to occupy ~ 29 Mha of the Cerrado, allowing 3.1 Mha for soy expansion and ~ 18 Mha for regeneration of savanna or other uses. Based on these future land-use scenarios, carbon stocks increase by up to 0.23 Pg in 2030 and 0.47 Pg in 2050.These scenarios suggest that existing open areas of the Cerrado can support livestock production, soybean expansion, additional agriculture, and regeneration, allowing increased carbon sequestration in the Cerrado biome without additional deforestation.

Periodontal disease and type 2 diabetes are interrelated, with inflammation playing a significant role in the progression of both conditions. Previous research has demonstrated the potential of various treatments, such as diet, exercise, and periodontal therapies, to improve glycemic control in diabetic patients. This study proposed a novel surgical approach, the Renew Procedure, as a potential solution to enhance glycemic control in type 2 diabetic patients with periodontal issues. The procedure involves the removal of all teeth, the elimination of oral and maxillofacial infections, the placement of dental implants, and the provision of implant-supported and implant-retained removable dentures. Preliminary findings indicated a significant reduction in HbA1c levels post-surgery, suggesting that this approach may improve overall oral health, reduce inflammation, and consequently lower HbA1c levels. Further research is necessary to confirm the efficacy of the proposed solution, but these initial results highlight the importance of addressing oral health through comprehensive strategies for diabetic and periodontitis patients.

Este trabalho aplica conceitos da Análise Multicritério Espacial para a prospecção de alternativaslocacionais para a instalação de empreendimentos de geração baseados em energias renováveis - representadas pelas fontes solar, eólica e biomassa - no Estado de Minas Gerais. Para apoiar a realização do estudo prospectivo, foi elaborada e aplicada uma metodologia de análise multicritério específica. Foram reunidos os critérios relevantes para a análise, os quais foram modelados como geocampos, com base em dados de fontes oficiais. Tais geocampos foramprocessados como conjuntos fuzzy concebidos de forma a refletir os objetivos da prospecção. Os resultados obtidos mostram que as áreas mais aptas para a geração renovável encontram-se, principalmente, nos Territórios de Desenvolvimento do Triângulo Mineiro, Norte e Central do Estado. Verifica-se ainda que Minas Gerais é um Estado com um considerável potencial para a geração renovável que, contudo, é subutilizado. Ao mesmo tempo, por meio de tal estudo, é demonstrado o potencial de aplicação da análise multicritério espacial para apoiar estudos prospectivos que precedem os complexos processos de tomada de decisão acerca de investimentos em geração, seja no ambiente governamental ou na iniciativa privada.

Nonlinear periodically poled ridge LiNbO3 waveguides have been fabricated on silicon substrates. Components are carved with only use of a precision dicing machine without need for grinding or polishing steps. They show efficient second harmonic generation at telecommunication wavelengths with normalized conversion reaching 204%/W in a 15 mm long device. Influence of geometrical non uniformities of waveguides due to fabrication process is asserted. Components characteristics are studied notably their robustness and tunability versus temperature.

It is very important to develop an effective, specific, and robust expression cassette that ensures a high level of expression in the mammary glands. In this study, we designed and constructed a series of mammary gland-specific vectors containing a complex hybrid promoter/enhancer by utilizing promoter sequences from milk proteins (i.e., goat β-casein, bovine αs1-casein, or goat β-lactoglobulin) and cytomegalovirus enhancer sequences; vectors containing a single milk protein promoter served as controls. Chicken β-globin insulator sequences were also included in some of these vectors. The expression of constructs was analyzed through the generation of transgenic mice. Enzyme-linked immunosorbent assay (ELISA) analysis revealed that the hybrid promoter/enhancer could drive the expression of recombinant human lactoferrin (rhLF) cDNA at high levels (1.17-8.10 mg/ml) in the milk of transgenic mice, whereas control promoters achieved a very low rhLF expression (7-40 ng/ml). Moreover, the expression of rhLF was not detected in the serum or saliva of any transgenic animal. This result shows that all constructs, driven by the hybrid promoter/enhancer, had high mammary gland-specific expression pattern. Together, our results suggest that the use of a hybrid promoter/enhancer is a valuable alternative approach for increasing mammary-specific expression of recombinant hLF in a transgenic mouse model.

It is tempting just to develop software in the usual way and then try to assure that the finished product is safe. This approach is akin to relying on downstream protection systems-the cost can be exorbitant and the assurance limited. The most practical and effective way to enhance software system safety is to follow a complete safeware program that applies safety enhancing techniques throughout software development and maintenance. Verification testing verifies that requirements for a subsystem have been met. Validation tests a finished device to the original requirements to ensure they have been met. Appropriately applied V and V decreases the cost of software development. Verification and validation can make a significant contribution in making the final product safe and effective. Software changes can be more easily and safely made when the development process is controlled and documented. The template is already in place. Regression testing is easily identified and can reduce the time required to make and test changes. The FDA requires evidence that verification and validation is included in the product development process. The emphasis is on appropriately applied V and V. A software development process that produces, on time, bug free code, meeting all of its requirements, and has intrinsic verification and validation identifying defects as early as possible, is a very cost efficient process, regardless of industry. The earlier a defect is found in the development process, the lower the cost to correct it.
