Overview: The global atmospheric CO2 concentration is rising and in 2013 it surpassed 400 parts per million for the first time in human history. Plants can sense CO2 concentrations in leaves and adapt transpiration accordingly. Ultimately, plants control gas exchange by opening and closing stomatal pores, which are highly responsive to changes in CO2 concentration, and CO2-mediated regulation of stomatal conductance has profound effects on plants. Among several signals that regulate stomatal movements, the stress hormone Abscisic Acid (ABA) plays a critical role in plant responses to abiotic stresses such as drought. The molecular signaling mechanisms and network principles by which CO2 and ABA control plant gas exchange were investigated. Three unbiased forward genetic screens were pursued and, after screening over 10,000 artificial microRNA lines and over 1,000 EMS mutagenized Brachypodium lines, partially ABA or CO2 insensitive lines were isolated and are currently being characterized. Major Goal: Due to the rising atmospheric CO2 concentration, CO2 control of gas exchange in plants will have profound effects on global water-transpiration, plant water use efficiency, leaf heat stress and optimal stomatal conductance of plants, including crops. Elevated CO2 concentrations in leaves cause stomatal closure, whereas reduced CO2 concentrations result in stomatal opening. However, little is known about the molecular signal transduction mechanisms that mediate CO2-induced stomatal movements, especially in grasses. Besides, the stress hormone ABA plays a key role in drought-induced stomatal closure, and the molecular pathways of CO2 and ABA converge, fine tuning stomatal movements in plants. My main goal was to identify and characterize new genes/proteins that play a role in CO2 and ABA signaling in plants, further elucidating these complex molecular pathways. Specific Goals: Three extensive forward genetic screens were pursued: 1- over 10,000 amiRNA lines were screened for ABA sensitivity, leading to the isolation of partially insensitive lines, 2- over 10,000 amiRNA lines were screened for low [CO2] sensitivity, leading to the isolation and characterization of lines and 3- over 1,000 EMS mutagenized Brachypodium lines were screened, leading to the isolation of two [CO2]-insensitive lines. As some of these finding have already been published (Hauser and Ceciliato et al., 2018 Journal of Experimental Botany), the other most relevant lines are being further investigated.

In 1984, Portugal was a middle-income country, developing the primary health care system, based on family doctors, health centres and health posts, reaching almost all population, with infectious diseases as one of the main health problems. In 2006, Mozambique was a low-income country, with a national health service attaining 60% of the population (40% in rural areas), with a double burden of disease (infectious and non-communicable diseases). Working in primary health care in Europe and Africa, we compare several experiences of family medicine practice in rural populations, different in context, time, and methods: Portugal 1984,Äì2006 and Mozambique 2007,Äì2020, all with a strong component of community health education. Our descriptive case studies, summarise strategies, interventions, and results, reviewing reports and articles. Population,Äô health indicators, and quality of life have improved, in different contexts with culturally tailored approaches. Participative societal diagnosis and multidisciplinary interventions are necessary to improve rural population health. Different rural populations and cultures are ready to learn and to participate in health promotion; empowering rural populations on health issues is an affordable strategy to better health indicators and services. Family Medicine is effective to extend primary health care to all rural populations, aiming universal health cover.

Incineration and landfilling of waste from the timber industry are practices condemned and unused. The reuse of wood waste as a dispersive phase in composite materials has been the focus of much research to develop new products, mainly for the automotive and construction industries. The wood-plastic composites (WPC) present characteristics, such as moderate strength, light weight, and high durability. Besides, they are inexpensive and sustainable, which make them attractive for innovative design. This work investigates the effect of eucalyptus sawdust, a chemical admixture and silica particles on the physical and mechanical properties of WPC upon a statistical methodology. The silica-particle addition was added by the matrix phase replacement to reduce the overall costs, because the latter is nearly 87 % more expensive. A microstructural analysis was conducted to better assess the variables studied. Results have shown that the composites made with 20 wt. % of sawdust addition, 10/50 US-Tyler sawdust particle size and maleic anhydride addition appeared to have acceptable properties for engineering applications.

The role of virus in the pathogenesis of oral mucositis (OM), either in its severity or as a triggering factor, in patient submitted to allogeneic hematopoietic stem cell transplantation (alloHSCT), has been timidly investigated in the last decades. The present study evaluated through the PCR and enzymatic digestion the oral excretion of Herpesviridae family in 32 adult patients submitted to alloHSCT (12 patients who developed OM and 20 patients who did not develop OM) pre, during and post-transplant. The samples were collected from the oral mucosa, supragingival and subgingival area at five moments of clinical follow-up, adding two more samples in patients who developed ulcerative OM, at beginning and at resolution of the lesion. By the moment that the samples were collected the detection of HSV-1, HHV-6A, HHV-6B, CMV, EBV and HHV-7 was observed in 4,34%, 4,34%, 5,53%, 6,32%, 19,36% and 43,08% in the group without OM and 3,84%, 0%, 1,7%, 2,13%, 18,8% and 71,79% in the group with OM, respectively. A qualitative analysis showed a lower presence in the subgingival site. The oral shedding of HHV-7 was significantly higher in group with OM. In most cases, the positive samples for EBV and CMV in the oral shedding were detected earlier than in the serologic samples. Six patients had positive samples for HHV-6B and 5 of them died because of the relapse of the disease or due to complications inherent to alloHSCT. These findings suggest that the presence of HHV-6B is a negative prognostic factor for patients submitted to alloHSCT.

"This thesis examines the link between airborne flux estimates of CO$ sb2$, sensible heat, and water vapor, and surface parameters retrieved by remote sensing. Chapter 1 analyses the relationship between surface temperature and vegetation indices, obtained from the Advanced Very High Resolution Radiometer on board of NOAA-9 and -10 satellites, and fluxes of sensible heat, latent heat, and CO$ sb2$, estimated from aircraft. Linear relationships between CO$ sb2$ and the Normalized Difference Vegetation Index (NDVI) or the Simple Ratio vegetation index (SR) are found on a daily basis, but a highly nonlinear relationship appears for the seasonal variation. Latent Heat fluxes showed the poorest correlations with surface parameters. A seasonal linear relationship appeared between sensible heat and NDVI. Local extreme flux values due to the intermittency of boundary layer dynamics largely contribute to lower the correlations; such variations are the reason for the difficulties in relating fluxes obtained from single overpasses and over short distances to fixed points at the surface. This problem is further examined in Chapter 2, in which conditional sampling of airborne flux estimates is used to characterize the turbulent structures that are carrying flux, and their link to the surface. The analysis confirms that few extreme events may carry a significant fraction of the flux. Missing or hitting one of these structures may translate into very large oscillations on the flux estimate that are often not directly coupled to surface characteristics. A much clearer surface ''signature'' emerges when measurements are taken within the surface layer, since the reorganization of turbulent structures that takes place with increasing height will result in a merging of the signature that came from different sources at the surface. This helps to explain some of the poor correlations obtained in Chapter 1 and reinforces the need for a better understanding of the distributions of these tu" --

Large wind stress curl caused by the funneling of winds through the Hawaiian Archipelago creates eddies in the lee of the islands. An ocean model is applied to understand the effect of temporal and spatial resolutions of the wind stress on the formation of eddies and on eddy kinetic energy levels. Only high-resolution winds produce values comparable to observations, demonstrating that the surface eddy field in the region is mostly dominated by the local winds. Modeled cyclones and anticyclones formed in the lee of the Hawaii are shown to have different propagation patterns. Anticyclones intensify and propagate west-southwestward, maintaining their coherence for a long time. Cyclones wobble in the region of relatively large eddy kinetic energy and often break down into filaments of positive vorticity. The Rossby number within the filaments and eddies is often O(1), in which case nonlinear effects become important. Nonlinear Ekman pumping is shown to be large in regions where the relative vorticity gradient is large. A biological model is embedded into the physical model and the high-resolution wind forcing is shown to affect the supply of new nutrients in the lee of Hawaii. Vertical flux of nitrate is much larger in the immediate lee than in the surrounding oligotrophic ocean. New production is enhanced during the formation stage of cyclones. The f-ratio increases from 0.2 to 0.8. As cyclones mature and decay, regenerated production dominates and the f-ratio decreases. Submesoscale motions, by creating large vertical velocities, are potentially the main drivers of the streaky chlorophyll-a pattern observed in the region. Numerical simulations show large vertical velocities associated with strong density fronts and gradients of relative vorticity. Vertical velocities derived from the Q-vector divergence yield good agreement with model vertical velocities. The agreement between model vertical velocities and nonlinear Ekman pumping is less satisfactory, although large values of both occur in similar places. The biogeochemical impact of these motions is potentially larger in the summer, with a shallower mixed layer. Hence, they could serve as a partial explanation for the appearance of late summer chlorophyll blooms northeast of the Hawaiian Islands.

ABSTRACT: The endless necessity for reducing production cycle time while achieving better quality forces metrologists to look for new and improved ways to perform the inspection of the parts being manufactured. The advent of coordinate measuring machines led to a significant boost in accuracy, flexibility and reliability for measurement tasks. However, these machines are in some instances lagging behind machine tools and need improvement. One major problem is the execution of measurements with low uncertainty at a reasonably fast rate to make it possible to measure more parts. This would ensure more reliability in the end product and better information to control the manufacturing process. Coordinate measuring machines with scanning capabilities offer the option to output high data density for parts at high speed. However, they are still considerably less accurate at faster measurement speeds and need to be improved. In this work a scanning measuring machine was extensively tested and a compensation model that accounts for part of the errors occurring during scanning measurement of circular features was proposed.

Implications of Industry 4.0 for enterprises in Upper Bavaria are still unclear. This working paper examines how key technologies of Industry 4.0 impact on performance objectives. The research methodology is based on a quantitative study carried out in in the larger area of Upper Bavaria with a focus on metal-mechanic and automotive sector. The results show which Industry 4.0 technologies have the highest implementation level and which technologies have the biggest impact on company performance objectives. Furthermore, the presented survey provides not only research on large companies, but analyze also micro, small and medium-sized enterprises in detail.

It is noteworthy that the modelling, sampling and convergence properties might be a critical issue in the PSP. From a computation perspective based on EAS, different modeling issues for PSP were revised in this Chapter. Although lattice models are relatively simple, they are very appealing for EAS approaches where the computational efficiency can be highly improved, enabling the prediction of better protein structures. In fact, the data structure based on AR + CM (Section 2) simplifies the objective function of lattice models since there is no need for an additional function penalizing amino acid collisions. As a consequence, the objective function uses only one criterion, i.e., the evaluation of the number of interactions between hydrophobic amino acids. The hydrophobicity of protein is a measure of the interplay of the protein and solvent interactions. The objective function of the lattice models based on AR + CM estimates this interaction. Thus, the EA using such model may also lead to a computationally efficient process in order to find protein conformations with more plausible solvent interaction. The solvent effect on PSP is an important issue: for most cases, the solvation energy basically drives the process. Different alternatives on how to model the solvent have been pointed out on Section 3. Despite the fact that some protein structure were successfully obtained with models based on potential energy functions with no hydration free energy contributions, this is not a general rule. For a general protein case, the solvation free energy and interaction.

The objective of this work was to evaluate of trees growth seasonality of a eucalyptus plantation fertilized with sewage sludge (SS) and K, complemented or not with P and/or B, and their respective response to meteorological variables. Therefore, in February 2015, a randomized block experiment was set up using clones of Eucalyptus (SP5727), with ten treatments and four replications, in a commercial area with water restriction (Cwa, Ku00f6ppen scale) and low soil fertility of the company Suzano Papel e Celulose S.A. The treatments were two levels of mineral fertilization, seven treatments with SS and K, supplemented or not with P and/or B, and one control. From 23 to 35 months after planting, a biweekly monitoring was carried out, using dendrometer bands, in five trees per plot. The treatments with application of 50%LE+86%P-B+K, 100%LE+66%P-B+K, 100%LE+66%P+B+K, 150%LE-P-B+K and the highest level of mineral fertilization presented a volume of wood (139 mu00b3 ha-1) higher than the control (125 mu00b3 ha-1). There was a smaller increase of transversal area in the period of low rainfall (July to October), with a high growth rate in October, after precipitation of 50 mm. The variables minimum temperature and potential evapotranspiration were the ones that most influenced the increment of the cross-sectional area, positively and negatively, respectively. The precipitation, although significant, showed low growth influence. There were no differences due to climatic variables between treatments. The fertilization of eucalyptus with sewage sludge promoted growth equivalent to the application of mineral fertilizer for high productivity.

This chapter presents the research done by authors in recent years on microstrip antennas and their applications in wireless sensors network. The subject is delimited to the study of conventional microstrip antennas, from which antennas with fractal and polar shapes are proposed. A detailed description of the antenna design methodology is presented for some prototypes of microstrip antennas manufactured with different dielectric substrates. Analysis of the proposed antennas has been done through computational simulation of full-wave methods. Experimental characterization of antennas and dielectric materials has been performed with the use of a vector network analyzer. The results obtained for the resonant and radiation parameters of the antennas are presented. Computer-aided design (CAD) of microstrip antennas and arrays using fractal and polar geometrical transformations results in a wide class of antenna elements with desirable and unique characteristics, such as compact, exclusive, and esthetic antenna design for multiband or broadband frequency operation with stable radiation pattern.
