13. Whole transcriptome organisation in the dehydrated supraoptic nucleus
The supraoptic nucleus (SON) is part of the central osmotic circuitry that synthesises the hormone vasopressin (Avp) and transports it to terminals in the posterior lobe of the pituitary. Following osmotic stress such as dehydration, this tissue undergoes morphological, electrical and transcriptional changes to facilitate the appropriate regulation and relea

14. Utilization of minimum quantity lubrication (MQL) with water in CBN grinding of steel
The use of cutting fluids is fundamental to machining processes, mainly when it comes to high heat generation, which is the case of grinding. Thus, lubrication and cooling provided by cutting fluids improve the final quality of the workpiece. However, cutting fluid usage provide some drawbacks concerning environmental, costs and health issues. Therefore, new

16. Clonagem molecular do gene ipaC de Shigella sp e estudo da expressão por Lactococcus lactis / Molecular cloning and expression analysis in Lactococcus lactis of ipaC gene from Shigella sp
Shigellosis is a severe intestinal infection caused by Gram-negative bacteria which belongs to the genus Shigella. It is a pathology with high incidence and it is known that 99% of cases occur in underdevelopment countries. Among these cases, 69% of them affect children under 5 years old. The high incidence of Shigella in underdevelopment countries, is mainl

17. Avaliação da resistência à compressão e da absorção de água de concretos utilizados após o tempo máximo de mistura e transporte especificado pela NBR 7212 / Evaluation of compressive strength and water absorption of concrete used after the maximum time of mixing and transport specified by NBR 7212
The Brazilian standard NBR 7212 (ABNT, 1984), for execution of ready-mixed concrete, specifies the maximum time for concrete to be discharged (used) completely in 150 minutes. The usage time of the concrete is due to reactions of the cement hydration and slump loss that occurs with fresh concrete, a normal phenomenon defined as the loss of fluidity along the

18. Adsorção de corantes têxteis utilizando biossorventes alternativos
The textile effluents when launched into water bodies reduce the penetration of sun light harming the photosynthesis processes. Besides this, the dyes have been pointed out as potentially toxic substances. In general, the removal processes are based on physicochemical systems followed by biological treatment. The sorption process, besides presenting high rem

22. Empirical study regarding the effects of minimum quantity lubricant utilization on performance characteristics in the drilling of Al 7075
Cutting fluids are difficult and expensive to recycle. These drawbacks mentioned can be reduced or eliminated by performing the cutting operations with minimum quantity lubrication or without using any cutting fluid. In this study, the effects of different cutting parameters on performance characteristics are studied empirically during the drilling of Al7075
