DISTÂNCIA DA REDE ELÉTRICA QUE VIABILIZA O USO DE MOTORES DIESEL EM ÁREAS IRRIGADAS DO BRASIL  Rodrigo Otávio Câmara Monteiro; Priscylla Ferraz; Rubens Duarte Coelho; Ronaldo Antônio do SantosEscola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, Piracicaba, SP [email protected]  1 RESUMO             Na maioria das regiões do país, a energia elétrica aparece como a alternativa, economicamente mais viável, no acionamento de bombas em áreas irrigadas, o que justifica seu uso por aproximadamente 70% dos irrigantes. No entanto, em determinadas situações, não se dispõe, nas proximidades, de rede elétrica, o que passa a viabilizar o uso de motores diesel. Este trabalho, portanto, propôs a análise dos custos horários de bombeamento com a operação de motores diesel e elétricos nas 5 regiões do Brasil. Considerou-se as composições tarifárias verde, azul e convencional, período de irrigação de 2, 4, 6 e 8 meses por ano e operação no horário de ponta e fora de ponta. Para essa avaliação, foi considerado um motor diesel e elétrico, de potência comercial de 50 cv. O ponto de equilíbrio entre motor elétrico e diesel foi determinado pela distância da rede de energia elétrica até o local de consumo. A viabilidade de utilização dos motores diesel em relação ao acionamento de motores elétricos foi encontrada a partir de distâncias da rede de transmissão elétrica de1,32 a8,71 km, sendo a primeira a condição mais atrativa, encontrada na região Sudeste, com 2 meses/ano de irrigação, na tarifa convencional. UNITERMOS: Energia elétrica, irrigação, custo de bombeamento  MONTEIRO, R.

VIABILITY OF DIESEL MOTOR USE IN IRRIGATED AREAS OF BRAZIL DUE TO DISTANCE FROM ELECTRIC POWER LINES  2 ABSTRACT In most agricultural areas ofBrazil, electric power seems to be the most feasible economic alternate methods for the functioning of pumps in irrigated areas, therefore 70%  of irrigation systems use it. However, the viability of electric power lines is restricted to only one part of rural areas, making it necessary the implementation of diesel engines as a source of electrical power for water management. The aim of this study was to investigate the viability of the use of electric energy and diesel motors.  For this study, an electric motor and a diesel one, both of 50HP potency, were evaluated, taking into consideration the following variables: tax composition, areas of the country and number of operation hours per year. The viability of the diesel engine use in relation to implantation of electric motors was determined from  distances that ranged from1.32 kmup to8.71 kmbetween the consumption place and the electric power lines. The most favorable condition is the one found in  the southeast of the country: 2 irrigation months/year.KEYWORDS: Electric energy, irrigation, pump costs

Broadband deployment in the United States is expanding rapidly but unevenly. Using new FCC census data on wireline and wireless broadband providers, the authors of this chapter study mobile broadband provision within the United States. Although rural areas lag behind non-rural areas in the availability of residential access to both mobile and fixed broadband, mobile broadband is at least partially filling in geographical gaps in fixed-line broadband coverage. Multiple regression results indicate that population density and growth, and the fraction of blacks, Hispanics, and youth in an area are positive predictors of the number of mobile broadband providers. The fraction of Native Americans, Asians, and senior citizens in an area are negative predictors. Income is positively associated with the number of providers, with largest effects in rural areas. Finally, even after controlling for population density and income, rural areas continue to be associated with a lower number of providers.

In the development of the energy industry in Russia, there has been a steady growth in the demand for electrical energy. Moreover, a significant increase in electricity consumption accounts for large cities. In rural areas, electricity consumption is mainly decreasing, which can be explained by the tendency of the outflow of the working-age population from the village and villages to the cities due to the lack of permanent work. However, when investing in the agro-industrial complex, with the development of farms, the demand for electricity also increases in villages. In addition, it is necessary to note the large-scale introduction of digital television and modern means of communication in holiday villages and villages. Thus, in the last decade, the demand for electricity throughout the country has increased significantly, which has led to an increase in communications and communications services, as well as consumers of these services. Since the easiest and most cost-effective way to provide consumer services and power supply is to lay down overhead lines and overhead power lines, it often happens that new customers are connected to already existing old (sometimes heavily worn out) lines. In addition to possible overloads of lines, a “tangle” of wires is formed at the intersections of overhead communication lines (VLS) and overhead transmission lines (VLE), which makes it difficult to carry out subsequent installation and repair work. The appearance of such a "tangle" creates an additional risk of injury to the worker when working at height. In order to reduce the complexity of maintenance and increase safety during operation, installation and maintenance of communication lines and power lines, a constructive solution has been proposed in junction intersections in the form of a traverse, which allows, firstly, to provide a greater number of attachment points and, secondly, to separate communication lines and power lines on different planes.
