The understanding of fish immune system structure and function is essential for the development of new technologies and products to improve productivity. This is the first review on immune system of fish with Brazilian studies. Aquaculture in Brazil has shown massive growth in recent years due to methods of culture intensification. However, these procedures led to disease outbreaks, as well as the chemotherapy and the misuse of antibiotics. A viable alternative to avoid the use of chemicals and prevent economic losses is the administration of immunostimulants and prebiotcs, which act by increasing the innate immune system. In Brazil there is a lack of studies on fish immune system, except by some groups that have studied the effects of the immunostimulants administration in various species.

Based on systemic-cybernetic-new paradigm vision and social constructionism, the paper is an invitation to reflect on the importance of language in the maintenance and the possibility of changing unequal relational patterns, mainly related to issues of gender. Studies on language and verbal behavior of women and men, besides their representation in the media, are examples to illustrate the need advocated here, to changing patterns of inequality guided by gender differences that influence and are influenced by the culture, conveyed in our social network. This paper is a contribution for the clinical work with families and couples, from the perspective of the current behaviors, based on refrains spread by the media which became popular, since it is based on clinical and nonclinical observations about human relationships and its representation in the media and artistic productions.

Due to the expansion of orchards, problems with soil pathogens are frequent and cause injury and/or make passion fruit cultivation impossible in Brazil. Thus, studies with potential species for rootstocks become indispensable to assist in the technological development of the culture. It is necessary to take into account several aspects of grafting, for the adoption of appropriate techniques, among them we can highlight the anatomy, physiology and also biochemistry. This study aimed to review the existing papers related to grafting of passion fruit and also to understand the operation of grafting itself. It was observed that several publications are related to the topic of the present review and that grafting is a viable alternative to the cultivation of passion fruit, however additional studies about grafting and production are needed.

The sunflower oleaginous is the fourth of recognized importance in the oil production and few studies related to agricultural operations adopted for this crop. The objective of the present work was to study the performance of agricultural machines in the conventional tillage and reduced in the plantation of the sunflower crop. The experiment was installed at the Experimental Farm of Lageado, belonging to the Faculty of Agricultural Sciences of UNESP, located in Botucatu-SP. It consisted of two types of tillage (conventional tillage-CC and reduced tillage-CR), with experimental design in randomized blocks and four replications. The treatment CC promoted less coverage of the soil surface protected with waste when compared to CR treatment. The chisel plow was the tillage of equipment that required the tractor higher average traction force, average power traction and slippage, consequently, promoted lower average speed of work. The theoretical field capacity and area of land involved in the treatment CR were superior when compared to treatment CC, thereby lower consumption of fuel per hour worked was lower in CR treatment.

Several factors induce soybean growers to seek new alternatives to increase productivity, in order to always surpass the previous harvest. In an attempt to meet this need in order to become more competitive, new technologies emerge. Currently, for example, the plantation system crossover, double row and dense, gaining media coverage and among researchers, aroused interest in research institutions. To date, there are still few studies with a scientific concrete, quantifies the real benefit of these cropping systems. The technique consists of sowing planting crossed the same area twice at right angles, forming checkerboard. In the planting row and the denser planting increases the number of plants per hectare, but the way they are arranged is what differentiates. Apparently these systems imply some issues, such as the use of inputs that the principle would double, as the plant population in the area will be changed, so possibly the incidence of insect pests and pathogens increase in these cropping systems. The purpose of this literature review is to provide updated information on technology, benefit from it, as it is being used and the research being conducted to provide scientific basis for soybean producer.
