In June 2014 Brazil hosted the FIFA World Cup and in August 2016 Rio de Janeiro hosts the Summer Olympics. These two seminal sporting events will draw tens of thousands of air travelers through Brazil’s airports, airports that are currently in the midst of a national modernization program to address years of infrastructure neglect and insufficient capacity. Raising Brazil’s major airports up to the standards air travelers experience at major airports elsewhere in the world is more than just a case of building or remodeling facilities, processes must also be examined and reworked to enhance traveler experience and satisfaction. This research paper examines the key interface between airports and airline passengers—airport check-in procedures—according to how much value and waste there is associated with them. In particular, the paper makes use of a value stream mapping construct for services proposed by Martins, Cantanhede, and Jardim (2010). The uniqueness of this construct is that it attributes each activity with a certain percentage and magnitude of value or waste which can then be ordered and prioritized for improvement. Working against a fairly commonly expressed notion in Brazil that Brazil’s airports are inferior to the airports of economically advanced countries, the paper examines Rio’s two major airports, Galeão International and Santos Dumont in comparison to Washington D.C.’s Washington National and Dulles International airports. The paper seeks to accomplish three goals: - Determine whether there are differences in airport passenger check-in procedures between U.S. and Brazilian airports in terms of passenger value - Present options for Brazilian government or private sector authorities to consider adopting or implementing at Brazilian airports to maximize passenger value - Validate the Martins et al. construct for use in evaluating the airport check-in procedures Observations and analysis proved surprising in that all airports and service providers follow essentially the same check-in processes but execute them differently yet still result in similar overall performance in terms of value and waste. Although only a few activities are categorized as completely wasteful (and therefore removed in the revised value stream map of check-in activities), the weighting and categorization of individual activities according to their value (or waste) presents decision-makers a means to prioritize possible corrective actions. Various overall recommendations are presented based on this analysis. Most importantly, this paper demonstrates the viability of using the construct developed by Martins et al to examine airport operations, as well as its applicability to the study of other service industry processes.

Realizaram-se estudos sobre sistemas de reprodução de Cassia spectabilis (L.) D C. (Leguminosae) observando-se a diversidade, freqüência e constância dos insetos visitantes em diferentes horários. Também testou-se a influência dos fatores ambientais em relação às visitas. Os resultados de polinização manual sugerem que C. spectabilis é autocompatível, porém, a xenogamia é o sistema de reprodução predominante. As inflorescências foram visitadas por uma grande quantidade de insetos, havendo predominância de abelhas. O horário de maior ocorrência dos insetos nas flores de C. spectabilis foi das 8 às 14 h e de menor ocorrência entre 7 e 8 h e das 17 às 18 h. Quanto ao comportamento dos insetos em relação à flor de C. spectabilis, observou-se que Xylocopa frontalis Olivier, X. suspecta Camargo & Moure, Bombus morio Swederus e Centris scopipes Friese possuem comportamento e morfologia adequados aos polinizadores legítimos; C. similis F., Oxaea flavescens Klug e Epicharis rustica flava Cockerell foram considerados polinizadores ocasionais. Pseudaugochloropsis graminea (F.), Tetragonisca angustula Latreille e A. mellifera L. foram considerados pilhadores. A polinização por vibração é o método usado pelas abelhas para coleta de pólen.

Brazil, one of the largest agricultural producers in the world, has managed in recent years to significantly improve its production. However, in response to this advance in the agro-industrial sector, the generation of agro-industrial residues has also increased. New technological alternatives have to be implemented in order to bring economic and rational use of this material and drying is one of the possible choices. Considering the great importance that bioactive compounds present for food science and technology, this research aims to evaluate the air-drying process of acerola residue in a tray convective drier under controlled temperature (60, 70 e 80ºC), air velocity (4.0, 5.0 e 6.0 m/s) and material width (0.5, 0.62 e 0.75 cm) by applying an experimental planning 23 + 3. Based on that, the impact on physical-chemical characteristics, color, bioactive compounds concentration and antioxidant activity of dried acerola waste was evaluated, having the in natura and freeze dried waste as control groups. Dried acerola residue presented natural pigments, mainly carotenoids (143.68 - 68.29 mg/g) and anthocyanins (290.92 - 90.11 mg/100 g), which explain the red and yellow instrumental color parameters observed. The acerola residue powder is also rich in phenolic compounds (3261.11 -2692.60 mgGAEeq/100g), proanthocyanidins (61.33-58.46 eq/100g), ascorbic acid (389.44 739.29 mg/100 g) and DPPH antioxidant activity (20.91 24.72 μg Trolox eq/g). Results show decreased concentration of phenolic compounds, anthocyanins, carotenoids, proanthocyanidins and ascorbic acid caused by the air-drying process. However, even after the observed drying losses, the acerola residue powder can be considered a high value food ingredient, considering the high bioactive compounds concentration found in the final product, as well as the colorimetric characterization and microbiological stability of the dried powder

Muitas espécies de Passiflora apresentam comportamento florífero diferente durante o ano e, consequentemente, com variações nas produções e períodos de colheitas, como observado para o maracujazeiro-amarelo (Passiflora edulis sims). Estudo com espécies silvestre constitui-se numa importante alternativa para usos de novos genótipos no melhoramento das espécies cultivadas comercialmente, em especial, a Passiflora setacea, devido ao grande potencial de mercado; contudo, essa espécie é pouco estudada, principalmente em relação à propagação, germinação, floração e condições de armazenamento. Assim, o objetivo deste trabalho foi avaliar o florescimento e a frutificação do maracujazeiro silvestre Passiflora setacea cultivado em Jaboticabal-SP. A floração e a frutificação foram avaliadas pelo percentual de frutificação através da polinização natural e artificial das flores, realizado no período de agosto a outubro. As características físicas dos frutos foram avaliadas através dos seguintes parâmetros: a) massa do fruto (g); b) diâmetro longitudinal do fruto (cm); c) diâmetro transversal do fruto (cm); d) espessura da casca (cm); e) rendimento de polpa (%). A característica química foi determinada por meio do teor de sólidos solúveis (SS). Verificou-se que a Passiflora setacea apresentou precocidade de floração em relação ao maracujazeiro-amarelo, com florescimento durante o ano todo, nas condições de Jaboticabal-SP. Observou-se que essa espécie possui bom nível de tolerância às doenças foliares, resistência à morte precoce e apresenta diferentes níveis de compatibilidade entre as plantas, possibilitando a essas características serem utilizadas em programas de melhoramento genético. Constatou-se ainda que as características físicas encontradas nos frutos atendem às exigências da indústria.

The species is a very popularly used plant as woundwort. Leaves, top flowers and rhizomes are used. The objective of this work is a contribution to the germination study, photoblastism and more adequate temperature for reproduction of the species. The best temperature for the germination was found to be 20°C and no seeds germinated under continuous darkness, within 14 days; therefore, the seeds are positive photoblastics. The seed germination percentage was low, in relation to the mass of the achene produced, varying from 8,2 to 20,0%. The alternated temperatures of 20° and 30°C did not influence the seed germination and the average of the weight of 100 seeds was 0,026 1 g.
