2. The PIN1 family gene PvPIN1 is involved in auxin-dependent root emergence and tillering in switchgrass
Abstract Switchgrass (Panicum virgatum L.; family Poaceae) is a warm-season C4 perennial grass. Tillering plays an important role in determining the morphology of aboveground parts and the final biomass yield of switchgrass. Auxin distribution in plants can affect a variety of important growth and developmental processes, including the regulation of shoot an

3. Bivalent RNA interference to increase isoflavone biosynthesis in soybean (Glycine max)
In this work, a bivalent RNA interference (RNAi) plant-transformation vector was constructed to silence both the flavanone 3-hydroxylase (F3H) gene and the flavone synthase II (GmFNSII) gene in soybean (Glycine max). Two further unit RNAi vectors were constructed for each of these two genes. RNAi-mediated suppression of these genes effectively regulated flav

4. A realidade estranha : um poética visual na sociedade da imagem e sua cultura dos imediatos / The strange reality : a poetic visual of the immediate
This thesis consists of theoretical research and visual practice with the aim of: 1) discuss the process of simulacrum on the field of representation taken by the construct of reality in contemporary society, and 2) production in the visual arts by seeking to create personal poetic in a hybrid regime. To establish a visual show was held a series of photograp

5. EstatÃstica de contagem de carga e efeitos de interferÃncia em sistemas mesoscÃpicos
In this thesis we presented a detailed study about full counting statistics of transmitted charge and accumulated phase and the quantum interference corrections to the average conductance and the average shot-noise power in non-ideal ballistic chaotic cavities. In the theoretical analysis of this mesoscopic system, we obtained analytical expressions for the

6. Interference of sorghum, braquiaria and pearl millet cover crops on maize and weeds / INTERFERÃNCIA DE PALHADAS DE SORGO, CAPIM BRAQUIÃRIA E MILHETO SOBRE CULTURA DO MILHO E PLANTAS DANINHAS
This work aimed to evaluate the effect of forage grass cover crops on corn (Zea mays), weed infestation and floristic weed composition. The treatments were three cover crops: Braquiaria (Brachiaria brizantha); pearl millet (Pennisetum glaucum) and inter specific sorghum hybrid BRS 800 (Sorghum bicolor x Sorghum sudanens) submitted to one cut 60 days after pl

7. STRUCTURES AND ADAPTIVE ALGORITHMS FOR BLIND DETECTION OF DS-CDMA SIGNALS / ESTRUTURAS E ALGORITMOS ADAPTATIVOS PARA DETECÇÃO ÀS CEGAS DE SINAIS DS-CDMA
Esta tese apresenta novas estruturas e algoritmos adaptativos para detecção às cegas de sinais DS-CDMA. São investigados receptores cegos com restrições lineares baseados nas funções custo de mínima variância (CMV) e módulo constante (CCM). Algoritmos adaptativos do tipo Affine-Projection para estimação dos parâmetros do receptor são desenvolv

8. STRUCTURES AND ALGORITHMS FOR MULTIUSER DETECTION AND INTERFERENCE SUPRESSION IN DS-CDMA SYSTEMS / ESTRUTURAS E ALGORITMOS PARA DETECÇÃO MULTIUSUÁRIO E SUPRESSÃO DE INTERFERÊNCIA EM SISTEMAS DS-CDMA
This thesis presents new structures and algorithms for multiuser detection and interference suppression in DS-CDMA systems. Structures based on recurrent neural networks are investigated for decision feedback receivers and adaptive algorithms are developed for combatting multiple access interference and intersymbol interference. New algorithms based on the m

9. AVALIAÇÃO METROLÓGICA DE VARISTORES DE ÓXIDO DE ZINCO PARA MÉDIA TENSÃO / METROLOGICAL EVALUATION OF ZINC OXIDE VARISTORS OF MEDIUM VOLTAGE
Despite its many benefits, one of the few disadvantages of semiconductor technology is the vulnerability of solid state devices to undesired increase in temperature, voltage and current . Even low voltage pulses can produce interference and damages with several consequences. Thus, as electronics are used in more and more applications, temperature, protection

10. Adaptative Antennas for Wireless Communications Systems / Antenas Adaptativas para Sistemas de Comunicações Sem Fio
Adaptive antennas is a radiating system that allows a control of the format and the direction of radiation diagram. With this control, they are capable to guide the main lobe of the radiation diagram to the desired signal and to reduce, simultaneously, the influence of the interferences signals. These systems have an accented demand in the technologies 3G an

11. Some experimental contributions to the study of the negative priming effect in selective attention tasks. / Algumas contribuições experimentais ao estudo do efeito de priming negativo em tarefas de atenção seletiva.
The development of sensitive and simple tests for the assessment of the negative priming effect has theoretical relevance to the elucidation of selective attention models, and also practical and potential clinical implications. The negative priming effect has been regarded as an index of inhibitory attentional processing and was proposed for the detection of

12. Dampening the silencing effect of RNA interference in mammals
RNAi (RNA interference) refers to the suppression of expression of a target gene (mainly at the post-transcriptional or translational level) induced by small (21–23 nucleotides) RNA molecules, including siRNA (small interfering RNA). Suppression of gene expression by RNAi represents an important part of the regulation of gene expression. Interestingly, rec
