Sistemas de armazenamentos hermético e convencional na conservabilidade de grãos de aveia (2004)

O presente trabalho objetivou avaliar a influência da umidade nos sistemas hermético e convencional durante doze meses de armazenamento de grãos de aveia branca (Avena sativa L) e indicar parâmetros de qualidade. Aveia, cultivar UPF 18, produzida na safra agrícola de 2001, foi colhida com 16% umidade e reduzida para 14%, 11% e 8% por secagem estacionária em um protótipo silo-secador. Os grãos foram armazenados nos sistemas hermético e convencional e determinado a umidade, lipídios, índice de acidez, germinação, vigor e contaminação fúngica após os períodos 0, 3, 6, 9 e 12 meses de armazenamento. A atividade residual das enzimas lipase e peroxidase foi realizada após a secagem dos grãos (tempo zero) e de composição em ácidos graxos e micotoxinas nos períodos 2 e 12 meses de armazenamento. Os resultados foram analisados pelo emprego da análise de variância e realizada a comparação múltipla de médias pelo teste de Tukey. Os sistemas de armazenamento hermético e convencional são eficientes para conservação de grãos de aveia com umidade de até 14%. O aumento do índice de acidez ao longo do período de armazenamento foi menor no sistema hermético quando comparado com o convencional. A incidência dos fungos de campo e de armazenamento foi maior na aveia conservada a 14% de umidade e no período de três meses. Não foi detectada presença de aflatoxinas B1 , B2, G1, G2, ocratoxina A e zearalenona em grãos de aveia armazenados por 12 meses.
Comparison of Insulin Regimens in Patients with Non-Insulin-Dependent Diabetes Mellitus (1992)

In patients with NIDDM who are receiving oral hypoglycemic drug therapy, the addition of NPH insulin in the evening improves glycemic control in a manner similar to combination therapy with NPH insulin in the morning, a two-insulin-injection regimen, or a multiple-insulin-injection regimen, but induces less weight gain and hyperinsulinemia. The data thus suggest that patients with NIDDM do not benefit from multiple insulin injections and that nocturnal insulin administration appears preferable to daytime administration.
Computer-assisted Analysis of Three-dimensional MR Angiograms (2002)

The software tools required for postprocessing of magnetic resonance (MR) angiograms include the following functions: data handling, image visualization, and vascular analysis. A custom postprocessing software called Magnetic Resonance Angiography Computer Assisted Analysis (MARACAS) has been developed. This software combines the most commonly used three-dimensional visualization techniques with image processing methods for analysis of vascular morphology on MR angiograms. The main contributions of MARACAS are (a) implementation of a fast method for stenosis quantification on three-dimensional MR angiograms, which is clinically applicable in a personal computer-based system; and (b) portability to the most widespread platforms. The quantification is performed in three steps: extraction of the vessel centerline, detection of vessel boundaries in planes locally orthogonal to the centerline, and calculation of stenosis parameters on the basis of the resulting contours. Qualitative results from application of the method to data from patients showed that the vessel centerline correctly tracked the vessel path and that contours were correctly estimated. Quantitative results obtained from images of phantoms showed that the computation of stenosis severity was accurate.
Effects of multipath angular spread on the spatial cross-correlation of received voltage envelopes (2003)

This paper presents a simple formula relating multipath angular spread to small-scale fading statistics. This formula is then applied to find an approximate spatial cross-correlation function for received voltage envelopes. The analytical approach is compared to 67 cross-correlation functions simulated with non-omnidirectional multipath. The equations in this paper provide insight for applying spatial diversity techniques to receivers operating in the presence of non-omnidirectional multipath.
Some remarks on radio-frequency holography (1967)

The extension of holographic techniques to radio frequencies offers new possibilities. The recording can be done by scanning an area with a probe. The reference wave can be replaced by a signal whose phase is varied with the probe position according to some program. Thus, "slow" reference waves (k > k <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</inf> ) can be simulated. Complex modulation schemes can also be used. A product detector can multiply the probe and the reference signal together and the recorded product can be used in the same manner as an intensity hologram. With two such "correlators," the probe signal can be obtained in phase and magnitude. Optical reconstruction can be done from this information.
Traction-drive transmission (1980)

A discussion is given of the Vadetec traction-drive transmission. It is claimed that when this traction-drive transmission is combined with an inertial drive line (energy storage system) and microprocessor control, fuel economy can be improved by 30 to 50 percent. (SC)
Decision tree classification of land cover from remotely sensed data (1997)

Decision tree classification algorithms have significant potential for land cover mapping problems and have not been tested in detail by the remote sensing community relative to more conventional pattern recognition techniques such as maximum likelihood classification. In this paper, we present several types of decision tree classification algorithms arid evaluate them on three different remote sensing data sets. The decision tree classification algorithms tested include an univariate decision tree, a multivariate decision tree, and a hybrid decision tree capable of including several different types of classification algorithms within a single decision tree structure. Classification accuracies produced by each of these decision tree algorithms are compared with both maximum likelihood and linear discriminant function classifiers. Results from this analysis show that the decision tree algorithms consistently outperform the maximum likelihood and linear discriminant function classifiers in regard to classf — cation accuracy. In particular, the hybrid tree consistently produced the highest classification accuracies for the data sets tested. More generally, the results from this work show that decision trees have several advantages for remote sensing applications by virtue of their relatively simple, explicit, and intuitive classification structure. Further, decision tree algorithms are strictly nonparametric and, therefore, make no assumptions regarding the distribution of input data, and are flexible and robust with respect to nonlinear and noisy relations among input features and class labels.
Myosin IIA suppresses glioblastoma development in a mechanically sensitive manner (2019)

The ability of glioblastoma to disperse through the brain contributes to its lethality, and blocking this behavior has been an appealing therapeutic approach. Although a number of proinvasive signaling pathways are active in glioblastoma, many are redundant, so targeting one can be overcome by activating another. However, these pathways converge on nonredundant components of the cytoskeleton, and we have shown that inhibiting one of these-the myosin II family of cytoskeletal motors-blocks glioblastoma invasion even with simultaneous activation of multiple upstream promigratory pathways. Myosin IIA and IIB are the most prevalent isoforms of myosin II in glioblastoma, and we now show that codeleting these myosins markedly impairs tumorigenesis and significantly prolongs survival in a rodent model of this disease. However, while targeting just myosin IIA also impairs tumor invasion, it surprisingly increases tumor proliferation in a manner that depends on environmental mechanics. On soft surfaces myosin IIA deletion enhances ERK1/2 activity, while on stiff surfaces it enhances the activity of NFκB, not only in glioblastoma but in triple-negative breast carcinoma and normal keratinocytes as well. We conclude myosin IIA suppresses tumorigenesis in at least two ways that are modulated by the mechanics of the tumor and its stroma. Our results also suggest that inhibiting tumor invasion can enhance tumor proliferation and that effective therapy requires targeting cellular components that drive both proliferation and invasion simultaneously.
Fracture Optimization Applying a Novel Traceable Proppant and a Refined Mechanical Earth Model in the Congo Onshore (2013)

Abstract Fracture stimulation has been adopted as an integral part of the completion in the M'Boundi field given the results achieved in enhancing well productivity, as well as the positive impact realized on field development economics. The fracturing process has been optimized over the years through improved reservoir understanding and ensuing implementation of technologies to address the uncovered challenges. Changes to the fracturing fluid formulation to prevent damaging the water sensitive reservoir rock, as well as modified proppant schedules to mitigate proppant embedment are examples of this improvement process. This paper describes the successful ongoing process of optimizing hydraulic fracturing designs in M'Boundi field. By applying an integrated approach combining various technologies, it was possible to better understand fracture propagation and coverage of the target reservoir. Implementation of a novel non-radioactive traceable proppant allowed accurate frac height measurement at the wellbore. When combined with rocks mechanics derived from sonic logs it led to redefining the mechanical earth model and ultimately the completion and fracturing strategy in the field. The process will be illustrated with examples from a 3-well campaign recently executed onshore Congo.

Web document clustering approach using wordnet lexical categories and fuzzy clustering (2008)

Web mining is defined as applying data mining techniques to the content, structure, and usage of Web resources. The three areas of Web mining are commonly distinguished: content mining, structure mining, and usage mining. In all these areas, a wide range of general data mining techniques, in particular association rule discovery, clustering, classification, and sequence mining, are employed and developed further to reflect the specific structures of Web resources and the specific questions posed in Web mining. In this paper, we introduced a Web document clustering approach that uses WordNet lexical categories and fuzzy c-means algorithm to improve the performance of clustering problem for Web document. Experiments show that fuzzy c-means algorithm achieves great performance optimization with comparison with the recent algorithms for document clustering.
EDT Bandwidth Management in SoC Designs (2012)

This paper presents preemptive test application schemes for system-on-a-chip (SoC) designs with embedded deterministic test-based compression. The schemes seamlessly combine new test data reduction techniques with test scheduling algorithms and novel test access mechanisms devised for both input and output sides. In particular, they allow cores to interface with automatic test equipment through an optimized number of channels. They are well suited for SoC devices comprising both nonisolated cores, i.e., blocks that occasionally need to be tested simultaneously, and completely wrapped modules. Experimental results obtained for large industrial SoC designs illustrate feasibility of the proposed test application schemes and are reported herein.
Photothermal technique using individual cantilevers for quality monitoring in thin film devices (2009)

An innovative photothermal technique has been developed to obtain optical absorption spectra of thin film devices. This technique is based on the bending effect induced by thermal expansion of a cantilever. The thin and transparent cantilever contacts a sample and when the sample is heated by photoexcitation, heat flows into the cantilever. The thermal expansion on sample side of the cantilever causes bending of cantilever beam. Main advantage of this method is adaptable to measure any sample structure and this can be used for quality monitoring in thin film devices such as solar cells and optical disks.
The role of portable electric fencing in biodiversity-friendly pasture management (2015)

Abstract World population is growing, and with it, the demand for food. In order to feed the world and attempt to slow the biodiversity crisis on the planet, farming practices must be altered to preserve species richness and ecological health. The fertile soil found in grassland biomes throughout the world provides a base for rich microorganism biodiversity, carbon sequestration, as well as water and nutrient cycling. Diverse biological communities are found in both natural and semi-natural grasslands; habitat destruction as a result of agricultural practices is a threat to biodiversity in these regions. While critics often blame modernized farming practices for agricultural pollution and habitat fragmentation, 21st century technology will likely be a means for updating farming practices to address both biodiversity conservation and enhanced efficiency for increased food demand. Recently developed portable electric fences, made of plastic netting and stainless steel, have made eco-agricultural practices, such as rotational grazing (RG) and multi-species pasture systems, easier and less expensive for farmers to put into practice than traditional electric fencing. Conflicting literature exists regarding whether or not RG systems outperform continuous grazing systems. Many studies suggest that more research is needed to observe the ecological benefits of RG on active farmland. Portable electric fences could be a valuable tool for completing additional research.
Tumor markers: A diagnostic tool (2016)

The purpose of this review is to give a brief background to enable the judicious use of widely performed serum cancer markers. The markers could be product of cancerous cell or as response to cancer. They are usually proteins, which are mainly found in blood or urine. These markers may be employed to predict primary or secondary tumor risk. Sometimes, non-cancerous conditions can also cause elevation of some tumor markers to be higher than normal. Besides, not every cancer patient may have raised level of a tumor marker. For these reasons, knowledge about cancer biomarkers has increased tremendously. Awareness for cancer and related tumor markers providing great opportunities for improving the management of cancer patients by enhancing the efficiency of detection and efficacy of treatment.
Neurobehavioral aspects of antioxidants in aging (2000)

Both aging and age-associated neurodegenerative diseases are associated with various degrees of behavioral impairments, and among the prime candidates responsible for producing the neuronal changes mediating these behavioral deficits appear to be free radicals and the oxidative stress they generate. Therefore, there have been a number of studies which have examined the putative positive benefits of antioxidants in altering, reversing, or forestalling these neuronal/behavioral decrements, with varying degrees of success. Additional experiments have examined the effects of diets rich in fruits and vegetables or herbal extracts in reducing certain types of cancer and cardiovascular diseases, and evidence emerging from such experiments suggests that these kinds of dietary modifications may be beneficial in altering neuronal/behavioral deficits in aging, as well. These kinds of diets are particularly rich in antioxidants such as vitamins A, C, E, and bioflavonoids (such as flavones, tannins, and anthocyanins), and thus, there may be synergistic effects among them. The present paper will review studies concerning the influence of dietary and synthetic antioxidants on normal, pathological age-related, and reactive oxygen species-induced behavioral changes in human and animal subjects. The antioxidants reviewed are vitamin E, alpha-lipoic acid, and the phytochemicals contained in herbals, fruits and vegetables.
Heterostructure acoustic charge transport device model (2002)

A small-signal circuit model for heterostructure acoustic charge transport (HACT) devices is derived from experimental data. The model includes the device transconductance, impulse, noise, and nonlinear responses. Data are presented which show how the transconductance and the noise floor are related to the quiescent current in the transport channel. Noise power is also related to the number of electrodes in the output array. The measured transconductance is 0.2-0.5 mS/mm for devices operating at 144 MHz. The noise current density in the transport channel is shown to vary as the square root of bias current. The noise power density in the output circuit is shown to vary as the square of the number of output electrodes. Design rules are presented which can be used to predict the noise floor gain, compression point, and dynamic range for a HACT device based on its transconductance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Nucleoside requirements for the in vitro growth of bovine aortic endothelial cells (1981)

The nutritional needs of cultured fetal bovine aortic endothelial cells were studied with regard to their nucleotide metabolism. When Medium 199 containing calf serum was supplemented with up to 5 microgram/ml of the deoxyribo- or ribonucleosides found in DNA or RNA, the rate of endothelial cell growth increased. The effect was entirely attributable to the pyrimidine nucleosides. The combination of deoxythymidine and deoxycytidine was much more effective than either deoxyribonucleoside used alone or than the combination of uridine and cytidine. Addition of deoxythymidine and deoxycytidine (each at 1 microgram/ml) to the medium supported the growth of endothelial cell cultures from initially sparse populations (ca. 50 cells/cm2), even at low concentrations (1%) of fetal bovine serum. The pyrimidine deoxyribonucleosides on their own were unable to stimulate cell growth; other bonafide growth stimulatory factors, such as those present in serum, serum dialysates, or retinal extracts, were needed in the medium to signal the initiation of DNA synthesis and cell replication. The significance of these findings with respect to improving cell performance under in vitro conditions and controlling endothelial cell growth in vivo are discussed.
Multidelay block frequency domain adaptive filter (1990)

A flexible multidelay block frequency domain (MDF) adaptive filter is presented. The distinctive feature of the MDF adaptive filter is to allow one to choose the size of an FFT tailored to the efficient use of the hardware, rather than the requirements of a specific application. The MDF adaptive filter also requires less memory and thus reduces the hardware requirements and cost. In performance, the MDF adaptive filter introduces smaller block delay and is faster, making it ideal for a time-varying application such as modeling an acoustic path in a teleconference room. This is achieved by using a smaller block size, updating the weight vectors more often, and reducing the total execution time of the adaptive process. The MDF adaptive filter compares favorably to other frequency-domain adaptive filters when its adaptation speed and misadjustment are tested in computer simulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Joint Multicast Routing and Channel Assignment in Multiradio Multichannel Wireless Mesh Networks Using Tabu Search (2009)

This paper proposes a tabu search (TS) based optimization approach to search a minimum-interference multicast tree which satisfies the end-to-end delay constraint and optimizes the usage of the scarce radio network resource in wireless mesh networks. The path-oriented encoding method is adopted and each candidate solution is represented by a tree data structure (i.e., a set of paths). Since we expect the multicast trees on which the minimum-interference channel assignment can be produced, a fitness function that returns the total channel conflict is devised. The techniques for controlling the tabu search procedure are well developed. A simple yet effective channel assignment algorithm is proposed to reduce the channel conflict. Simulation results show that the proposed TS multicast algorithm can produce the multicast trees which have better performance in terms of both the total channel conflict and the tree cost than that of a well known multicast algorithm in wireless mesh networks.

Stability of mode locked states of coupled oscillator arrays (1995)

A method for analyzing beat frequency entrained (or mode locked) systems of coupled nonlinear oscillators is presented. Stable mode locked states are almost periodic oscillations that occur outside of the fundamental entrainment region of the array, and generate a periodic pulse train when the oscillator outputs are summed. The analysis relates the stability of the states to the relationship between the frequency pullings and the time average phases of the oscillators. The method is applied to three mode locked Van der Pol oscillators with arbitrary coupling time delay, and shows that the mode locking bandwidth is maximized for specific values of coupling delay and oscillator nonlinearity parameter.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
