Influence of soil water potential in the action of herbicides on goosegrass (Eleusine indica (L) Gaertn)

Currently, the use of herbicides is essential in a practical and common in agricultural areas, but efficiency of these herbicides can be compromised when applied on plants that thrive in water deficit conditions, due to low uptake and translocation of the product. Therefore, the aim of this study was to compare the efficiency of control ACCase inhibiting herbicides applied post-emergence in plants of Eleusine indica under different soil water contents. The experiment was conducted in a greenhouse and the experimental design was completely randomized design with four replications, consisting of a 9x4 factorial, with the combination of three soil water potentials (-0.03, -0.07 and -1.5 MPa) three herbicides (fluazifop-p -butyl, haloxyfop-methyl and sethoxydim + oil) and four doses (0, 25, 50, and 100 % of the recommended dose). Herbicide application was made in plants in vegetative stage 2-3 tillers. The soil water potential was initiated in the development stage of two leaves, and the water was supplemented until the soil reaches the potential of -0.01 MPa, when it came to minimum pre-determined for each water management. The physiological parameters evaluated were: photosynthetic rate, stomatal conductance, transpiration leaf temperature and plant dry mass. The visual assessments of phytotoxicity were performed at 7 and 14 days after application. The herbicides behaved in different ways according to the used water management. In severe water stress conditions (soil moisture at 8%) only fluazifop-p-butyl herbicide achieved satisfactory control (> 90%) in E. indica plants.

The affective-emotional communication in shoppingscapes: case study

Shoppingscapes on urban roads, such as streets and avenues, require study and more specific attention. You must be aware of the emotional communication, an important factor with regard to the influence on the perception and acquisition process by the observer. Reaching the consumer cognitively, arousing emotion and desire to want to have the observed object is one of the goals of emotional communication, and that only happens with the proper use of elements of perception. This paper aims to highlight the need for interdisciplinary design and architecture, especially in the case of shoppingscapes in open spaces that sell fashion items. The case study raises a reflection on the elements of perception in the windows as to whether they are being clearly communicated. It also discusses how the same are interfering or being interfered by the shoppingscapes of Avenida da Liberdade in Lisbon.

Plano de responsabilidade social empresarial para a Raízen: projeto 4 patas

The process of globalization resulted in a variety of new products emerging. Companies were obliged to find new ways of maintaining the attractiveness for their products to sustain their brands in the economic field. So in this scenario social accountability became an important subject for companies that want to achieve a positive image among consumers. This paper aims to explain how organizational communication is essential to create and manage social accountability in a company. Aiming to explain the relation between organizational communication and social accountability, this final project had three main purposes: establish the connection between organizational communication and social accountability, point out and discuss the main strategies in this communication field, and then propose an action plan for Raízen to solve an established problem in one of its factories
