1. TECHNICAL AND ECONOMIC FEASIBILITY OF USING A VARIABLE-FREQUENCY DRIVE IN MICRO-IRRIGATION SYSTEMS
ABSTRACT Irrigation is essential for the development of crops in regions with scarcity or irregular rainfall distribution, enabling high productivity. However, the use of water resources and electrical energy leads to a concern with irrigation efficiency. Pressure demand varies during the operations of irrigation systems and the appropriate pressure can be r

4. GÊNERO, SEXUALIDADE E O SEXUAL: O SUJEITO ENTRE BUTLER, FOUCAULT E LAPLANCHE
RESUMO Neste trabalho, articulamos um debate crítico entre Butler, Foucault e Laplanche para pensar a constituição do sujeito a partir das categorias centrais utilizadas por esses pensadores: o gênero, a sexualidade e o sexual. Primeiro, desenvolvemos a ideia de jogos libidinais de poder: os jogos de poder foucaultianos não se sustentam sem um suporte l

5. Investigation on Solar PV generation and design of switched reluctance motor for Smart Agriculture actuation system
ABSTRACT This paper presents standalone solar photovoltaic (PV) powered fed actuation system employing a switched reluctance motor (SRM) particularly used in remote and rural areas. The converter efficiency is achieved by changing ON and OFF state of solar PV drive. An electronic commutation drives SRM drive with achieved by position hall sensor and encoder.

6. HARVESTING FRUITS USING A MOBILE PLATFORM: A CASE STUDY APPLIED TO CITRUS
ABSTRACT Harvesting fruits and vegetables has been a challenge. Mobile platforms for harvesting vegetables and fruits have been used, but with some limitations, such as their applicability for a certain time of the year and for a specific crop. A mobile platform was initially developed for harvesting fresh market tomatoes, mainly staked in Brazil. However, a

7. EFFECTIVE POWER AND HOURLY FUEL CONSUMPTION DEMANDED BY SET TRACTOR- COFFEE HARVESTER IN FUNCTION OF ADEQUACY TRACTOR BALLASTING
ABSTRACT: The mechanized gathering process of sweeping coffee is extremely important to reduce the losses of fruit not used in the harvesting operation. But this operation usually has a low operational performance and a high cost per unit collected in this way any measures that can effectively reduce costs increase the viability of the operation. In this sen

12. THROUGH THE LENS OF SPINOZA: THE DRIVE SEEN AS POTENCY / ATRAVÉS DAS LENTES DE SPINOZA: A PULSÃO COMO POTÊNCIA
Para Freud, o conceito de pulsão é um dos mais importantes da psicanálise e é imprescindível à psicologia. A despeito de sua relevância e centralidade conceituais, a obscuridade e a imprecisão que permeiam essa definição sempre levantaram questões controversas. A teoria das pulsões sofreu remanejamentos, acréscimos e correções ao longo da prod
