Efeito do porta-enxerto e da época de poda na duração das fases fenológicas e no acúmulo de graus-dia pela videira 'Niagara Rosada'

It was evaluated the influence of rootstocks 'IAC 766', 'IAC 572', 'IAC 313', 'IAC 571-6' and 'Ripária do Traviú' and the pruning periods in the duration of phenological stages and in the accumulation of degree-days on grape 'Niagara Rosada' .The experiment was conducted in Louveira, SP. The treatments consisted of five rootstocks and three times of pruning, the experimental design being used in a completely randomized split plot with five replications, and plots represented by rootstocks and the subplots were pruning. After pruning the grapevine, were realized evaluations for phenological stages, using the criterion of Eichhon e Lorenz (1984). ). In three seasons of pruning, based on phenological stages, it was calculated the length of the periods: pruning to budding, pruning to the beginning of the flowering, pruning to the beginning of fruiting, pruning to beginning of ripening of the bunches, pruning the beginning of the harvest. Taking as a basis the cycle length of the vine and the average daytime temperatures, it was calculated the accumulation of degree-days. Data were submitted to ANOVA and Tukey test at 5% significance level. It was obtained in the summer pruning the reduction in duration of the phenological stages of 'Niagara Rosada' grafted on the rootstock 'Ripária Traviú'. The longer duration of the cycle and accumulation of degree-day of 'Niagara Rosada' cultivar were obtained with the rootstocks 'IAC 572' and 'IAC 313' pruning in the winter.

Viabilidade e longevidade de sementes de tabebuia aurea benth. & hook. submetidas a diferentes métodos de armazenamento

Seeds Tabebuia aurea (syn. Handroanthus aureus Mattos), The seeds of Tabebuia aurea (syn. Handroanthus Mattos aureus), have low metabolic rates, which favors their storage conditions and freezing temperatures when stored at room temperature, there is a progressive decline in viability. Therefore, this study aims to determine the viability and longevity of seeds of Tabebuia aurea subjected to different storage methods. There were used 6100 seeds. In 2400 seeds were stored refrigerator, which in 1200 placed in transparent plastic bag and 1200 in Kraft paper bags. 3600 Other seeds were placed in room temperature and 1200 seeds in clear plastic bag, 1200 in Kraft paper bags and tray open in 1200. For each treatment, four replicates of 25 seeds for 12 months, with design was completely randomized. The average germination, normal seedlings and speed germination index were transformed into (x+1)(-1/2). The data were submitted to ANOVA and means compared by Tukey test at 5%. Also regressions polynomials were modeled for the variables study in function of the periods of storage of the seeds. The seeds stored in the refrigerator at 13 C maintained a high germination rate and normal seedling germination rate during the 360 days of evaluation. The method suitable for the seed storage of Tabebuia aurea is in the refrigerator at 13 degrees C, both in plastic and paper.

Interação fungo micorrízico arbuscular e adubação fosfática no crescimento e absorção de nutrientes pelo porta-enxerto limoeiro Cravo

Estudou-se o efeito da inoculação com fungo micorrízico arbuscular (FMA), Glomus etunicatum, Glomus clarum, ou Scutelospora heterogama, e da adição de fósforo solúvel (15, 30, 45, 60, 120 e 240 mg de P kg-1 de terra) sobre as variáveis altura, número de folhas, diâmetro do caule, massas vegetais aérea e radicular, teores de nutrientes nas folhas e colonização micorrízica no porta-enxerto limoeiro Cravo (Citrus limonia (L.) Osbeck). Os FMAs, Glomus etunicatum e Glomus clarum, e doses crescentes de fósforo exerceram efeitos significativos sobre essas variáveis. O efeito da inoculação sobre as variáveis de crescimento vegetal foi mais acentuado nos tratamentos com adição de 30 a 60 mg de P kg-1 de terra. Para o teor de P foliar, o efeito da inoculação foi mais acentuado nos tratamentos adicionados de 120 a 240 mg de P kg-1 de terra. A inoculação com estes FMAs aumentou a eficiência do limoeiro Cravo em absorver nutrientes, tanto que as variáveis estudadas em plantas inoculadas na ausência de adubação fosfática superaram às de plantas não inoculadas em substrato adicionado de 240 mg de P kg-1 de terra.

Sistema de monitoração de bloqueios tipo porta de vidro

Automatic video surveillance system has been a frequent topic of research due to the large number of promising applications. In this research, we developed a tracking and counting people system, as well as suspicious activities detector. The model tracks individual objects as they pass through the field of vision of the camera using vision algorithms to classify the activities of each person, and according to this features, detect dangerous situations. This dissertation includes a review of several techniques trying to develop a robust and low computacional costs system to be used in glass door barrier turnstiles avoiding fraud

Utilização da instrumentação virtual em Labview para criação da interface gráfica do amplificador lock-in utilizado em estudos fisiológicos a partir da comunicação via porta serial

This work presents the development of a graphical interface to the Lock-in Amplifier, which is used in physiological studies on the motility of the gastrointestinal tract in rats and signal processing. With a simple and low cost instrumentation, the resources offered by the virtual interface of LabVIEW software allows the creation of commands similar to the actual instrument that, through communication via standard serial port, transmits data between a PC and peripheral device performing specific and particular needs in the amplifier. Created for the lock-in amplifier model SR830 Stanford Research Systems, the remote manipulation gives the user greater accessibility in the process of configuration and calibration. And, since the software is installed, there is the advantage of eliminating the need of purchase new devices to upgrade the system. The commands created were made to perform six basic modifications that are used in routine of the Biomagnetism Laboratory. The instrumentation developed has the following controls: Amplitude, Frequency, Time Constant, slope low pass filter, sensitivity and offset
