Nutritional and Health Benefits of Carrots and Their Seed Extracts  [PDF]
Jo?o Carlos da Silva Dias
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.522227
Abstract: Carrot is a root vegetable with carotenoids, flavonoids, polyacetylenes, vitamins, and minerals, all of which possess numerous nutritional and health benefits. Besides lending truth to the old adage that carrots are good for eyes, carotenoids, polyphenols and vitamins present in carrot act as antioxidants, anticarcinogens, and immunoenhancers. Anti-diabetic, cholesterol and cardiovascular disease lowering, anti-hypertensive, hepatoprotective, renoprotective, and wound healing benefits of carrot have also been reported. The cardio- and hepatoprotective, anti-bacterial, anti-fungal, anti-inflammatory, and analgesic effects of carrot seed extracts are also noteworthy. All are discussed in this review article.
Plant Breeding for Harmony between Modern Agriculture Production and the Environment  [PDF]
Jo?o Carlos da Silva Dias
Agricultural Sciences (AS) , 2015, DOI: 10.4236/as.2015.61008
Abstract: The world population is estimated to be 9.2 billion in 2050. To sufficiently feed these people, the total food production will have to increase 60% - 70%. Climate models predict that warmer tem-peratures and increases in the frequency and duration of drought during the present century will have negative impact on agricultural productivity. These new global challenges require a more complex integrated agricultural and breeding agenda that focuses on livelihood improvement coupled with agro-ecosystem resilience, eco-efficiency and sustainability rather than just on crop productivity gains. Intensifying sustainability agro-ecosystems by producing more food with lower inputs, adapting agriculture to climate change, conserving agro-biodiversity through its use, and making markets to work for the small farmers are needed to address the main issues of our time. Plant breeding has played a vital role in the successful development of modern agriculture. Development of new cultivars will be required while reducing the impact of agriculture on the environment and maintaining sufficient production. Conventional plant breeding will remain the backbone of crop improvement strategies. Genetic engineering has the potential to address some of the most challenging biotic constraints faced by farmers, which are not easily addressed through conventional plant breeding alone. Protective measures and laws, especially patenting, must be moderated to eliminate coverage so broad that it stifles innovation. They must be made less restrictive to encourage research and free flow of materials and information. Small farmers have an important role in conserving and using crop biodiversity. Public sector breeding must remain vigorous, especially in areas where the private sector does not function. This will often require benevolent public/private partnerships as well as government support. Active and positive connections between the private and public breeding sectors and large-scale gene banks are required to avoid a possible conflict involving breeders’ rights, gene preservation and erosion. Plant breeding can be a powerful tool to bring “harmony” between agriculture and the environment, but partnerships and cooperation are needed to make this a reality.
Guiding strategies for breeding vegetable cultivars  [PDF]
Jo?o Carlos da Silva Dias
Agricultural Sciences (AS) , 2014, DOI: 10.4236/as.2014.51002
Abstract:

Vegetables are considered essential for well-balanced diets. The production and marketing of vegetables crops are undergoing continuous change globally. This is mainly due to the growing demands of consumers for safe and healthy vegetables, increased urbanisation of societies, and the growth in scale and influence of supermarkets chains. Horticultural science can respond to many of these challenges through research, breeding and innovation that can seek to gain more efficient methods of crop production, refined post-harvest storage and handling methods, newer and higher value vegetable cultivars and demonstration of their health benefits. Vegetable breeding has to address and satisfy the needs of both the consumer and the producer. Innovation in vegetable breeding depends on specific knowledge, the development and application of new technologies, access to genetic resources, and capital to utilise them. The driving force behind this innovation is acquiring or increasing market share. Access to technology, as well as biodiversity, is essential for the development of new vegetable cultivars. A few multinational corporations, whose vast economic power has effectively marginalized the role of public sector breeding as well as local, small/medium-scale seed companies, dominate the global vegetable seed trade. For most vegetable crops, only a few multinational seed corporations are controlling large part of the world market. This situation makes a growing part of the global vegetable supply dependent on a few seed providers. The multinational seed corporations ensued from merging some small or medium vegetable breeding programs to reduce costs. There may be fewer vegetable breeders in the future and growers will rely on seeds with a narrow genetic base. In order to meet future needs of vegetable breeders it is important that educational programs incorporate rapidly changing new technologies with classical content and methods. Active and positive connections between the private and public breeding sectors and large-scale gene banks are required to avoid a possible conflict involving breeders’ rights, gene preservation and erosion. Horticulturists will need to develop cultural practices and vegetable breeders to breed vegetables for a multifunctional horticulture (diversity, health promotion, post-harvest, year round suply, etc.) and to cope with harsher climate conditions and

Deus está do nosso lado: excepcionalismo e religi?o nos EUA
Fonseca, Carlos da;
Contexto Internacional , 2007, DOI: 10.1590/S0102-85292007000100005
Abstract: the goal of this paper is to analyze the origins and the evolution of america?s religious foundational myths, and their role in the inception of the idea of "exceptionalism", the main determinant of us political identity as expressed in foreign policy.
Vidas presas: uma tentativa de compreens?o da tragédia da criminalidade junto às suas personagens prisioneiras
Rocha, Luiz Carlos da;
Psicologia USP , 2006, DOI: 10.1590/S0103-65642006000300006
Abstract: this article presents a research about the producer factors of criminality done in the beginning of 80s which, with the support of long interviews with female prisoners, elaborated a group of hypotheses to the understanding of the established relations that this phenomenon keeps with the poverty, with the police/prison violence and with the own specialized knowledge through which their acts and actors become object of knowledge. its presentation, today, has two aims: the first is, in honor of recognition and gratitude to sylvia leser de mello, to offer a simple example of one of many research adventures propitiated by her orientation. the second is to share with researchers the subject in study that, polemic and innovative to its epoch, keeps importance to its characteristic specially serious, nowadays, shown by approached issues.
O programa de gerenciamento dos resíduos laboratoriais do Depto de Química da UFPR
Cunha, Carlos Jorge da;
Química Nova , 2001, DOI: 10.1590/S0100-40422001000300023
Abstract: the laboratory waste management program of the chemistry department of ufpr started on 1997 and was developed to meet the requirements of co-processing in cement kiln and those of the respective regulation. the in-lab procedures for waste collection and treatment were devised taking into account their cost, simplicity and wide range of application to the various types of residues generated. the program works with a five step annual journey : 1) waste collection and treatment, 2) bulk storage, 3) licensing (for transportation and co-processing), 4) transportation and 5) co-processing.
O Governo George W. Bush e o relacionamento EUA -América Latina
Fonseca,Carlos da;
Rela??es Internacionais (R:I) , 2008,
Abstract: this article offers an evaluation of the united states relationship with latin america during buhs?s two terms at the white house. we argue that the main trend of the bush administration in latin america has been a process of ?hemispheric disengagement? which has led to the erosion of american influence in the region, a problem that the next president will have to address, be he a democrat or a republican.
