The importance of the forager palm as one of the most important grass, for your high productivity and quality for the ruminant. However, this research had the objective to evaluate the vegetative growth, production and composition chemistry-bromatologic of the joined forager palm with caja (Spondias spp) in the semi-arid person from the state of Ceará. The experiment was led in the Experimental Farm, in Quixadá, CE in the period from 2003 to 2007, with the planting accomplished in November of 2003 in soil classified like texture Luvissolo Sandy Franco. The experimental desig was randomly blocks with factorial by 2x2x2 with 4 repetitions, with the following treatments: T1 - Plant Sun Not Fertilized east/weast; T2 - Planting Fertilized Sun east/weast; T3 - Plant Sun Not Fertilized Noth/South; T4 - Planting Fertilized Sun North/South; T5 - Plant Shadow Not Fertilized east/weast; T6 - Plant Shandow Fertilized east/weast; T7 - Plant Shandow Not Fertilized North/South; T8 - Plant Shandow Fertilized North/South. In the treatments with manuring 1 kg/cov of tanned bovine manure was placed, corresponding to 20 t / ha. The plant used for the shandow it was the caja (Spondias ssp.), spaced of 7 x 7 m and cup with 1.5 m of height. To accomplish the measures morphometric length, width and thickness used a ruler of 50 cm and a caliper, respectively. During the collection of each plant the cladodes were numbered by order, being the primary cladodes those original of the cladode base, the secondary ones those original of first order and so forth and heavy. Soon after a composed sample was removed to determine the tenors of Fiber in Acid Detergent, Lignina, Ethereal Extract, Crude Protein, ash. For the appraised parameters a variance analysis was accomplished to verify the significant of the factors (sun and shade, east/weast and north/south, fertilized and not fertilized and the interaction among the factors) and the averages compared by the test of Tukey to 5% of probability. Significant effect was verified (P<0.05) for interaction sun/shade and fertilized/not fertilized for the variable length, width, thickness of the cladodes, productivity of the forager palm, ash and total carbohydrates. Already for the Fiber in Acid Detergent verified significant effect (P<0.05) for the interaction sun/shandow and east/weast, north/south. Conclude that in the edafoclimatic conditions where the experiment was lead, the organic fertilization and the plantation in the sun they induce to one better performance of the forager palm (Opuntia fícus-indica (L.) Mill). / No Nordeste brasileiro a eficiência da produção animal foi incrementada ao combinar pastagens nativas e forrageiras adaptadas em conseqüência da baixa produtividade das forrageiras nativas, principalmente na época de estiagem. Tendo em vista a importância da palma forrageira como um dos mais importantes recursos forrageiro, pela sua elevada produtividade e qualidade para os ruminantes. No entanto, essa pesquisa teve o objetivo de avaliar o crescimento vegetativo, produção e composição químico-bromatológica da palma forrageira consorciada com cajá (Spondias spp) no semi-árido cearense. O experimento foi conduzido na Fazenda Experimental Lavoura Seca, em Quixadá, CE no período de 2003 a 2007, com o plantio realizado em novembro de 2003 em solo classificado como Luvissolo de textura Franco Arenosa. O delineamento experimental foi blocos ao acaso com arranjo fatorial 2 x 2 x 2 com 4 repetições, com os seguintes tratamentos: T1 – Plantio Sol Não Adubado Leste/Oeste; T2 – Plantio Sol Adubado Leste/Oeste; T3 – Plantio Sol Não Adubado Norte/Sul; T4 – Plantio Sol Adubado Norte/Sul; T5 – Plantio Sombra Não Adubado Leste/Oeste; T6 – Plantio Sombra Adubado Leste/Oeste; T7 – Plantio Sombra Não Adubado Norte/Sul; T8 – Plantio Sombra Adubado Norte/Sul. Nos tratamentos com adubação foi colocado 1 kg/cova de esterco bovino curtido, correspondendo a 20 t/ha. A planta utilizada para o sombreamento foi a cajá (Spondias ssp.), espaçadas de 7 x 7 m e copa com 1,5 m de altura. Para realizar as medidas morfométricas comprimento, largura e espessura utilizou uma régua graduada de 50 cm e um paquímetro, respectivamente. Durante a coleta de cada planta os cladódios foram numerados por ordem, sendo os cladódios primários aqueles originários do cladódio base, os secundários aqueles originários de primeira ordem e assim sucessivamente e pesados. Em seguida foi retirada uma amostra composta para determinar os teores de Fibra em Detergente Ácido, Lignina, Extrato Etéreo, Proteína Bruta, Resíduo Mineral. Os dados obtidos foram submetidos a análise de variância para verificar a significância dos fatores (sol e sombra, leste/oeste e norte/sul, adubado e não adubado e a interação entre os fatores) e as médias comparadas pelo teste de Tukey a 5% de probabilidade. Foi verificado efeito significativo (P<0,05) para interação sol/sombra e adubado/não adubado para as variáveis comprimento, largura, espessura dos cladódios, produtividade da palma forrageira, resíduo mineral e carboidratos totais. Já para a Fibra em Detergente Ácido foi verificado efeito significativo (P<0,05) para a interação sol/sombra e leste/oeste norte/sul. Conclui-se que nas condições edafoclimáticas em que foi conduzido o experimento, a adubação orgânica e o plantio no sol induzem a um melhor desempenho da palma forrageira (Opuntia fícus-indica (L.) Mill).

Essa busca esteve presente e evoluiu em sua riqueza de expressão na trajetória dos trabalhos fotográficos realizados entre 2009 e 2014. Inicialmente, essas experiências se fizeram pela interação entre fios de cabelo, a luz ambiente e seu espaço; Depois, bambuzais com suas variações de luz natural. A procura culminou com a aplicação de valores técnicos, estéticos e poéticos ¿ conquistados nos primeiros trabalhos ¿ na investigação da antena de teletransmissão da TV Cultura, localizada na cidade de São Paulo. A fotografia e o vídeo serviram de suporte no registro do objeto e suas manifestações diretas no tempo e no espaço. A interpretação desse material privilegiou as relações compositivas das fotografias, fundamentadas em aproximações com alguns artistas da vanguarda do construtivismo russo (1917-1930) e o concretismo brasileiro representado por Geraldo de Barros no período entre 1940-1950, quando trabalhou suas "fotoformas". Os acasos provenientes das imagens obtidas no decorrer deste estudo até a Antena da TV Cultura surpreendem pelas afinidades inatas aos ângulos de visão, à técnica e aos temas fotográficos comuns do processo de amadurecimento de artistas na década de 1920 / Abstract: This study proposes the analysis and the deepening of poetic language perceived in photographic records on the interaction between the phenomena of light, time and space. This search was present and evolved into its wealth of expression in the trajectory of photographic works made between 2009 and 2014. Initially, these experiences occurred by the interaction between hairs, ambient light and space. Then, bamboo groves with their variations of natural light image effects. The search followed its path with the application of technical, aesthetic and poetic values - studied in the initial works ¿ to the research of the TV Cultura remote transmission antenna, located in São Paulo. Photography and video provided the technology bases to observe and record the object and its direct manifestations in time and space. The interpretation of this material prioritized the composing relations between the images captured in photographs, based on the conceptual approaches of the Russian constructivism¿s avant-garde artists (1917-1930) and Brazilian concretism represented by Geraldo de Barros (1940-1950), when he worked his "photoforms". The results obtained from the images captured during this study to the TV Culture¿s antenna surprise due to the affinities in viewing angles, technique and thematic photographic, subjects of these artists maturation process in the 1920s / Doutorado / Artes Visuais / Doutora em Artes

Eight fossil leaves identified as Exbucklandia tengchongensis sp. nov. (Hamamelidaceae) were collected from the Pliocene Mangbang Formation in Tengchong, Yunnan Province, Southwest China. The fossil leaves are characterized by the overall rounded lamina with entire margin, actinodromous venation, and cyclocytic stomata, which suggest the affinity within the genus Exbucklandia, particularly with E. populnea. A survey on the cuticles of the sun and shade leaves of modern E. populnea indicates that the shade leaves generally possess more pronounced undulate anticlinal cell walls and a much lower stomatal density than the sun leaves. Two morphotypes, i.e. sun vs. shade types, of the fossil leaves were therefore recognized. The distribution of the modern Exbucklandia suggests that the genus lives under a warm climate with a mean annual temperature (MAT) from 13 °C to 27 °C and a mean annual precipitation (MAP) from 800 mm to 2500 mm. Hence, E. tengchongensis might also live under a similar climatic condition in the Pliocene. Leaf margin analysis on the Tengchong flora supports this result. The little change of Neogene MAT in Southwest China is therefore supported.

The theory that fruit abscission may be the result of a reduction in metabolites available to the young fruit was addressed by this study. Shade cloth or terbacil, a photosynthetic inhibitor, were applied to limbs and whole trees to examine the influence of treatment and time of application on fruit nonstructural carbohydrates and abscission. 'Stayman' apple limbs shaded with 92% shade material from 5-15, 10-20, 15-25, 20-30, and 25-35 days after full bloom (April 22) had lower fruit retention than unshaded controls on 11 June. On 18 June, fruit diameter was greater on limbs shaded between 5-25 days after full bloom (DAFB) than on unshaded limbs. At 15, 20, 25, and 30 DAFB, fruit from limbs shaded for 10 days had lower total nonstructural carbohydrates (TNC), total sugars, and reducing sugars (% dry wt) than fruit from limbs shaded for 0 or 5 days. Terbacil (3-tert-butyl-5-chloro-6-methyluracil) was applied at 0, 50, 100, and 200 ppm to whole nine-year-old 'Redchief Delicious' apple trees at 15 DAFB. Terbacil markedly inhibited Pn; recovery occurred by 9 and 26 DAA for the 50 and 100 ppm rates, respectively. Phytotoxicity prevented the determination of Pn in the 200 ppm treated trees. Fruit dry weight, TNC, total sugars, and reducing sugars (% dry wt and mg/fruit) declined with increasing rates of terbacil. Total fruit abscission was observed 12 DAA for the 100 and 200 ppm treatments, while the 0 and 50 ppm applications retained 4.6 and 1.4 fruit per cm² limb cross sectional area (LCSA) at 35 DAA, respectively. Compared to the control, 50 ppm terbacil decreased fruit number and weight at harvest, but increased fruit weight. Terbacil at 75 ppm and 92% shade material were applied to whole, 3-year-old 'Redchief Delicious' trees at 18, 23, and 28 DAFB. Generally, fruit dry weight, total sugars, and reducing sugars were lowered by both shade and terbacil treatments. In most cases, fruit from shaded trees were lower in dry weight and measured nonstructural carbohydrates than fruit from terbacil-treated trees after 5 or 10 days of treatment. Shading for 5 or 10 days resulted in total fruit drop. Terbacil at 75 ppm resulted in 0.8 as opposed to 2.9 fruit per cm² LCSA on the controls at 54 DAFB. / M.S.

The primary goals of this research were to develop an improved design for measuring tympanic temperature in groups of beef cattle, determine the ideal operating parameters of the new device, and to verify its effectiveness in a research application. Development of the continuous tympanic temperature logger (CTTL) consisted of two steps: identifying a small temperature logger capable of adequate data storage and constructing a probe to hold the logger and fit in the ear canal of a bovine animal. The minimum sampling interval needed to measure tympanic temperature in beef cattle was calculated using Fourier analysis. In addition, the differences in core body temperature between three measurement locations (left ear, right ear, and vagina) were quantified. The CTTL was also used to record the thermoregulatory responses of feedlot heifers with access to shade provided by three different materials.

Uluru is the more famous of the two namesake inselbergs found in Uluru Kata-Tjuta National Park (UKTNP). Uluru is roughly 10 km around its base, stands nearly 350 m tall, and can cast a shadow more than a kilometre long during the early morning and late afternoon hours. Additionally, there are many areas near the base of Uluru that receive nearly continuous shade throughout the day, which may also mean that these places could be buffered against extreme temperatures. This study investigated Uluru's influence on the climate at various distances from its base, and simultaneously assessed if the structure of the reptile community was related to the observed climatic variation. We used iButton data loggers to record the temperature and relative humidity at 26 sample locations surrounding Uluru. We used ArcGIS to map the path of Uluru's shadow and to determine when and how long data loggers recorded in and out of Uluru's shading influence. We found that the temperature and relative humidity were strongly influenced by Uluru's shadow, and that reptile assemblages were strongly correlated with the amount of time a sampled site was influenced by Uluru's shadow.
