Pesticides Analysis in Beans by Gas Chromatography Couplet with Tandem Mass Spectrometry

Beans are part of the basic diet alimentation for Brazilian population, as they gather proteins, carbohydrates, vitamins, mineral salts, fibers, amino acids and essential nutrients such as iron and calcium, being a complete food that can be compared with the amount of protein that the meat has. Considering the beans world production, in development countries represent almost 50%, being that Myanmar, India and Brazil the top three position. The use of pesticides is widely spread in these countries to reduce agricultural losses due to pests that interfere with grain production. Therefore the risk that could be generated from foods pesticides residues makes their analyses of quantification mandatory. The purpose of this work was to develop an analytical method to quantitatively characterize fungicides pesticides residues, flutriafol, procymidone and tebuconazole that were used to angular spot control, anthracnose, rust and alternaria spot, white mold fungi, present in beans, by means of gas chromatography coupled with a triple quadrupole mass spectrometer. Samples of beans, Phaseolus vulgaris L, types white, black, string and Vigna angularis, type adzuki, had been bought in grains store and supermarkets at metropolitan São Paulo city. The validation of analytical method was explored for sensitivity, selectivity, precision. The extraction procedure was performed in two different forms, QuEChERS, and solid-liquid extraction with low temperature. Through this methodology, reached below the maximum limit allowed by Brazilian law 0.5mgkg-1 for procymidone and 0.1mgkg-1 for flutriafol and tebuconazole. Several samples of four types of beans were tested and all of them had procymidone identified and 7% of samples higher than the law limit.
Linking quality citizenship to process design: a quality management perspective

As organisations emphasise their role in society, there is a need to determine the effect of socially responsible practices on organisational processes and firm performance. Although the effect of corporate social responsibility on firm performance has been addressed from different perspectives, little is known about the influence of corporate social responsibility on organisational processes and internal operations of firms. The paper aims to make a link between corporate social responsibility, quality management practices and quality outcomes through emphasising quality citizenship as one of the practices associated with quality management. This paper provides a new perspective on the link between quality citizenship and product/process design within the quality management framework. The stakeholder theory of the firm is used to explain the formation and development of new management practices within a firm. Data were collected from managers in the petroleum industry to examine the role of quality citizenship on design and development of organisational processes. The results show that quality citizenship has a significant effect on employee involvement and an indirect effect on process design. Quality citizenship enables firms to obtain a much broader perspective on product/process design and facilitates design and development of products, services and processes that meet the needs of a broader set of customers – the stakeholders.
Monte Carlo study of current variability in UTB SOI DG MOSFETs

The scaling of conventional silicon based MOSFETs is increasingly difficult into the nanometer regime due to short channel effects, tunneling and subthreshold leakage current. Ultra-thin body silicon-on-insulator based architectures offer a promising alternative, alleviating these problems through their geometry. However, the transport behaviour in these devices is more complex, especially for silicon thicknesses below 10 nm, with enhancement from band splitting and volume inversion competing with scattering from phonons, Coulomb interactions, interface roughness and body thickness fluctuation. Here, the effect of the last scattering mechanism on the drive current is examined as it is considered a significant limitation to device performance for body thicknesses below 5 nm. A simulation technique that properly captures non-equilibrium transport, includes quantum effects and maintains computational efficiency is essential for the study of this scattering mechanism. Therefore, a 3D Monte Carlo simulator has been developed which includes this scattering effect in an ab initio fashion, and quantum corrections using the Density Gradient formalism. Monte Carlo simulations using `frozen field' approximation have been carried out to examine the dependence of mobility on silicon thickness in large, self averaging devices. This approximation is then used to carry out statistical studies of uniquely different devices to examine the variability of on-current. Finally, Monte Carlo simulations self consistent with Poisson's equation have been carried out to further investigate this mechanism.
National Power Laboratory power quality study 1972 to 1979 revisited

This paper describes the five-year power quality study being conducted by National Power Laboratory (NPL) with a comparison to the Allen-Segall (IBM) and Goldstein-Spetanza (AT&T) studies. The graphics capabilities of the NPL monitoring system are also described with selected waveforms from the study used as examples. Comparisons are based on 1057 site months of the NPL database and the IBM and AT&T study information. Threshold levels for defined disturbances in these comparisons were selected to exactly match the original IBM and AT&T thresholds. This equivalent comparison produces a profile of power quality for 1990-1995 based on the monitor capabilities, definitions, and threshold settings of the 1972 IBM and 1979 AT&T studies. Results of the comparisons show major changes in the number and types of power disturbances, as reported in the original 1972 and 1979 studies. A common result found in all three studies is the need for computer-grade power to protect essential sensitive electronic equipment. A paper coauthored by NPL and Bellcore also concluded that backup powering is needed if commercial AC voltage is used by local exchange carriers for powering fiber-in-the-loop (FITL) systems. Some "typical" waveforms recorded during the study are also shown as examples as to what is happening at the point of utilization.
An Improved Method for Accurate Sound Localization

When implementing out-of-head sound localization with headphones, it is well known that using head-related transfer functions (HRTFs) other than those of a listener degrades sound image localization, and enhances localization error and front-back confusion. Some studies have indicated that moving a sound image eases these problems. We focus on moving sound images to achieve highly accurate localization, and propose a swing sound image method that enables sound image swing between two locations on a horizontal plane. Listening tests reveal that the proposed method greatly reduces the front-back confusion.
The reality of homes fit for heroes: design challenges for rehabilitation technology at home

It is widely accepted that rigorous rehabilitation exercises after a stroke can help restore some functionality. However for many patients, this means exercises at home with minimal, if any, clinician support. Technologies that help motivate and promote good exercises offer significant potential but need to be designed to realistically take account of real homes and real lives of the people who have had a stroke. As part of the Motivating Mobility project, we carried out a series of visits to homes of people living with stroke and photographed their homes. In contrast to many utopian smart home scenarios, the elderly of today live in homes that were built as homes fit for heroes' but have been evolved and adapted over time and present significant challenges for the design of in‐home rehabilitation technologies. These challenges include the uses and repurposing of use of rooms, attitudes to and uses of existing technologies, space available in the home, feelings about different spaces within homes and individual preferences and interests. The findings provide a set of sensitivities that will help shape and frame ongoing design work for the successful deployment of rehabilitation technologies in real homes.
A Spatial Model of a Vibrating Conveyor Taking Into Consideration The Self-Synchronisation Process of Inertial Vibrators. Analysis of The Effect of The Layout of The vibrators On The Operation of The Conveyor

This article presents a spatial model of a vibrating conveyor supported on steel-elastomer vibration isolators and vibrated by two inertial vibrators as well as the results of analyses of the effect of the layout of vibrators on the operation of the conveyor. The displacement of the line of action of the resultant of the forces of the vibrators beyond the centre of mass of the machine body manifests itself in the departure of the machine body from the desirable rectilinear motion and problems associated with the unevenness of material movement. The model presented in this article takes into account an extremely important coupling between vibrators and the body of the machine, which is responsible for the process of self-synchronisation of the vibrators and the correctness of machine operation. The results of theoretical analyses presented in this paper were verified by laboratory tests and reference to observations based on the authors’ industrial experience.
Comparison of dispersion compensation for DQPSK modulated formats in 100Gbps DWDM optical communication system

This paper investigates the performances of 16×100Gbit/s return-to-zero differential quadrature phase shift keying (RZDQPSK) coded modulation signals in dense wavelength division multiplexing (DWDM) system and compares three different dispersion compensation fiber (DCF) methods. The performance has been evaluated by using Q value as the major parameter along with the variation of the input power for different channels with different dispersion compensation schemes. It is observed that symmetrical compensation of DCF is more excellent than pre-compensation and post-compensation methods. Corresponding to symmetrical compensation of DCF method, the maximum values of Q factor are 11.7026, 10.5128 and10.5138 for channel NO.1, channel NO.8, and channel NO.16, respectively. Meanwhile, the eye diagram shape of symmetrical compensation method is superior to the others.
Experimental study on Operculina turpethum in STZ induced diabetic neuropathy, neurodegeneration and cardiovascular complications

Neuropathy and Cardiac complications are the most common trouble in diabetes mellitus with progressive damage due to complex pathogenesis. Many conventional pharmacological agents were withdrawn from clinical studies either due to lack of efficacy or due to side effects on major organs. Over the period of time traditional herbal plants were utilized in the treatment & management of diabetic complications. The aim of the present research work was to investigate efficacy and dynamics of Operculina turpethum root (OT) in STZ induced diabetic neuropathy and cardiac complications. Chronic treatment of crude extract of OT (500 mg/kg) showed positive effect in diabetic animals with significant reduction in blood glucose level, serum nitrite, brain homogenate nitrite & nerve homogenate nitrite levels as compared to diabetic control animals. Treatment with OT showed significant rise in body weight compared to Control animals & polyphagia were observed in diabetic animals persisted throughout the period of 8 weeks. Significant improvement was observed by treatment with OT in behavioural parameters like tail flick latency reduction and rise in pain threshold capacity. Nerve conduction velocity measured through BIOPAC system showed significant (P<0.05) improvement in diabetic animals, while improvement were observed in ECG profile, R-R interval, R wave amplitude, heart rate & cardiac hypertrophy index in diabetic animals when treated with OT. It was concluded from results that there is definite role of Operculina turpethum in the treatment and management of major diabetic complications.
Factors Affecting Organizational Performance NRD San Diego FY 1997-2000: A Systems Analysis

Abstract : This thesis is a descriptive, comparative organizational analysis of Navy Recruiting District, San Diego during two time periods: Fiscal years 1997-1998 and 1999-2000. The purpose of this study was to determine those factors affecting organizational performance in the primary area of Enlisted Recruiting production of the district in both time periods using a systems analysis. Based on model comparisons, document reviews, interviews, and personal communications with the leaders, supervisors and recruiters of NRD San Diego, analysis indicates that the district of FY97-98 was ill-equipped in strategy, resources and processes to perform effectively in a more demanding environment. The heightened goal requirements and increased number of recruiting personnel placed on all recruiting districts between 1997 and 1998 exposed NRD San Diego's system weaknesses, resulting in lower indicators of successful performance. The FY99-OO district appeared to handle change better including higher indicators of successful performance such as process improvements, energetic leadership, flattened communication and work flow structures and a well-defined direction. The district's enlisted production performance improved from 1997 to 2000.
Entwicklung von opischen 3D CMOS-Bildsensoren auf der Basis der Pulslaufzeitmessung

In this thesis, a 3D CMOS imager based on time-of-flight (TOF) has been developed and successfully tested. It uses an active pulsed class 1 laser operating at 910nm to illuminate a 3D scene. The scene depth is determined by measurement of the travel time of reflected pulses by employing a fast on-chip synchronous shutter. A so-called Multiple Double Short Time Integration (MDSI) enables suppression of the background illumination and correction for reflectivity variations in the scene objects. The sensor chip contains two pixel lines with each pixel containing twin photodiodes, thus the chip contains 4´64 sensors. The chip allows tow operating modes; the first is the binning mode, where the twin pixels are short-circuited (tow lines on the die) and the average signal is measured. The second mode is the high-resolution mode. In this mode the pixels operate separately (four lines on the die). The chip has been realized in 0.5mm n-well standard CMOS process. The pixel pitch is 130mm. To get a good fill factor, the readout circuitry is located at the sides of the chip.

Layered Channel Estimation for High Data Rate DS-UWB

In this paper, a layered channel estimation method is proposed for DS-UWB systems, where both ISI and IPI are taken into consideration. The multipath components are classified into layers with respect to their time delays and estimated layer-by-layer iteratively. In each layer, the ISI and IPI are mitigated by using the inherent characteristics of bipolar symbols and prior knowledge of the spreading code sequence and pilot symbols. A detection-directed refinement procedure is used to improve the estimation accuracy further. Simulation results show that the proposed scheme can be used to gain precise channel state information.

Red LED light promotes hair follicle development to improve fibre quality in Su line Angora rabbit

Background: Light has crucial roles in animal physiological activities. This study aimed to investigate the effects of different colours of light-emitting diodes (LEDs) on rabbit fibre quality and hair follicle development. 50 three-month-old Su line Angora rabbits were randomly assigned to five groups. Treatment groups were exposed to same intensities of red, green and blue LED light under 16 h light:8 h dark photoperiod regimes. Control groups were exposed to white light and black. The trial spanned 73 days. Results: Results showed that LED colours exerted different effects on wool yield, fibre quality, hormones and hair follicle development. The wool yield of red group was higher than that of white, green and black groups (P<0.05). The shoulder fibre length of red group was higher than that of white and green groups (P<0.05). The coarse fibre diameter of white group was lower than that of green and black groups (P<0.05). The fibre diameter of red group was the lowest and was lower by 13.9% than that of control group (P>0.05). The coarse fibre ratio of green group was higher (13.31%) than that of red group (3.81%, P<0.05). The follicle groups of white, green and black groups consisted of 1 primary follicle associated with 3 or 4 secondary follicle groups and those of blue group consisted of 1 primary follicle associated with 5–10 secondary follicle groups. The follicle of red group consisted of numerous secondary follicles and a few primary follicles. In same magnification, the numbers of follicle groups of white, red, green, blue and black groups were 14.0, 16.5, 10.0, 11.67 and 11.0, respectively. The numbers of follicle groups of red and green groups significantly differed (P<0.05). Serum melatonin (MT) of red group was highest than that of white and green groups (P<0.01), higher than that of black group (P<0.05), serumTriiodothyronine (T 3 ) of red group was higher than that of white and black groups (P<0.05). Conclusions: Thus, the data reveal that red LED light can improve fibre quality, this may be due to red LED light which can enhance the secretion of melatonin to promote hair follicle development .
Romance N Prep N constructions in visual word recognition

N Prep N constructions such as Sp. bicicleta de montaña ‘mountain bike’ are very productive and frequent in Romance languages. They commonly have been classified as syntagmatic compounds that show no orthographic union and exhibit an internal structure that resembles free syntactic structures, such as Sp. libro para niños ‘book for children’. There is no consensus on how to best distinguish lexical from syntactic N Prep N constructions. The present paper presents an explorative eye-tracking study on N Prep N constructions, varying both lexical type (lexical vs. syntactic) and preposition across three languages, French, Spanish and Portuguese. The task of the eye-tracking study was a reading aloud paradigm of the constructions in sentence context. Constructions were fixated on less when more frequent, independent of lexical status. There was also modest evidence that a higher construction frequency afforded shorter total fixation durations, but only for lower deciles of the response distribution. The (construction-initial) head noun also received fewer fixations as construction frequency increased, and also when the head noun was more frequent. The second fixation durations on the head noun also revealed an effect of lexical status, with syntactic constructions receiving shorter fixations at the 5th and 7th deciles. The probability of a fixation on the preposition decreased with preposition frequency, but first fixations on the preposition increased with preposition frequency. The prepositions of Portuguese, the language with the richest inventory of prepositions, received more fixations than the prepositions of French and Spanish. The observed pattern of results is consistent with models of lexical processing in which reading is guided by knowledge of both higher-level constructions and knowledge of key constituents such as the head noun and the preposition.
Protection Scheme for Island Operated Medium-Voltage Microgrid

During island operation, high fault currents from the utility grid are not present. Also, most of the distributed generation units that are connected to microgrid, are likely to be inverter interfaced and have limited fault current feeding capabilities. Due to that, during microgrid island operation, conventional distribution system protection schemes which assume a single path for the fault current and a high fault current level when compared to the load current, can be less efficient, may have slower fault clearing time and be less sensitive and selective. Several solutions have been proposed and many of the proposed solutions rely on the use of high-speed communication links to send tripping or blocking signals between relays. This paper proposes a new protection scheme, including both short-circuit and earth-fault protection, for island operated medium-voltage distribution network (microgrid) having multiple protection zones without the need for high-speed communication. The proposed protection scheme is not dependent from fault current contribution of the units and takes into account and is selective with low-voltage-ride-through curves of the units.
A novel method of achieving flat spectral response arrayed waveguide grating (AWG) in silicon-on-insulator (SOI)

Arrayed Waveguide Gratings (AWG) have gained significant popularity in Wavelength Division Multiplexing (WDM) in recent years. One of the most important characteristics of an AWG is to have a flat spectral response in order to maximize the performance of the device and reduce crosstalk. In this paper, we present a novel method of achieving a flat spectral response AWG in silicon-on-insulator (SOI). This is achieved using free carrier doping, which ultimately introduces absorption which alter the intensity field distribution at the output of the array waveguides. By applying Fourier optics to the free space region of the AWG, this field profile is the inverse Fourier transform of the output field at the AWG, hence producing a flat spectral response. The rib of the arrayed waveguides is designed to operate in singlemode condition and exhibit minimum polarization dependence. The AWG is designed to operate at a centre wavelength of 1. 55μm at a grating order of 51 with path length differences of 22. 61μm. Particular emphasis is paid to the theoretical analysis and development of a flat spectral response AWG, including a number of different implantation doses.
