Characterization of genes involved in the regulation of programmed cell death in Arabidopsis thaliana

Geprogrammeerde celdood (PCD) is een belangrijk onderdeel in de levenscyclus van meercellige organismen. Het is de eliminatie van ongewenste of ernstig beschadigde cellen via een complex en genetisch gecontroleerd proces. Het doel van het onderzoek van Kamran Qureshi was genen te karakteriseren die betrokken zijn bij de regulatie van PCD in de onderzoeksmodelplant Arabidopsis thaliana . PCD is een complex en genetisch gecontroleerd proces, waarbij zowel AAL-toxines als ROS fungeren als signaalmoleculen die de inductie en uitvoering starten van de PCD-cascade in planten. AAL-toxines zijn gastheerspecifieke stoffen, uitgescheiden door de ziekteverwekkende schimmel Alternaria alternata f. sp. lycopersici, die giftig zijn voor planten. ROS zijn reactieve zuurstof deeltjes. Beide soorten signaalmoleculen leiden tot een massale herprogrammering op het transcriptionele niveau. In het bijzonder bestudeerde Qureshi de rol van vroeg gereguleerde genen tijdens de door ROS en AAL-toxines veroorzaakte PCD. Daarnaast heeft hij genen geisoleerd en gekarakteriseerd met een mogelijkerol in de door ROS en AAL-toxines veroorzaakte PCD. Qureshi wist zodoende aan te tonen dat mutaties in deze genen leiden tot tolerantie voor ROS-en AAL-toxines, wat wijst op een relatie tussen AAL-toxines en ROS tijdens de PCD. De identificatie van regulators is van belang voor het begrijpen van het complexe proces van PCD. Daarnaast kunnen deze regulators nuttig zijn bij het begrijpen van verdedigingsmechanismen van planten tegen pathogene aanvallen en ophoping van ROS veroorzaakt door externe prikkels.

A tower model for lightning overvoltage studies based on the result of an FDTD simulation

This paper describes a method for deriving a transmission tower model for EMTP lightning overvoltage studies from a numerical electromagnetic field simulation result obtained by the FDTD (Finite Difference Time Domain) method. The FDTD simulations carried out in this paper take into account the following items which have been ignored or oversimplified in previously presented simulations: (i) resistivity of the ground soil; (ii) arms, major slant elements, and foundations of the tower; (iii) development speed of the lightning return stroke. For validation purpose a pulse test of a 500‐kV transmission tower is simulated, and a comparison with the measured result shows that the present FDTD simulation gives a sufficiently accurate result. Using this validated FDTD‐based simulation method the insulator‐string voltages of a tower for lightning strokes are calculated, and based on the simulation result the parameter values of the proposed tower model for EMTP studies are determined in a systematic way. Since previously presented models include trial‐and‐error process in the parameter determination, it can be said that the proposed model is more general in this regard. As an illustrative example, the 500‐kV transmission tower mentioned above is modeled, and it is shown that the derived model closely reproduces the FDTD simulation result. © 2008 Wiley Periodicals, Inc.

Analysis of demand and access to services in the last two weeks previous to the National Health Survey 2013 and 2019.

OBJECTIVE Compare the demand and use of health services between 2013 and 2019, and analyze the associated sociodemographic and health variables in 2019. METHODS Cross-sectional study with data from the National Health Survey (PNS) 2013 and 2019. The prevalence and 95% confidence intervals (95% CI) for the demand and use of health services were estimated. In 2019, the differences in the indicators were analyzed according to sociodemographic variables and the crude and adjusted by sex and age prevalence ratios (RP) were estimated. RESULTS There was an increase of 22% in the demand for health care in the last two weeks, going from 15.3% (95%CI 15.0-15.7) in 2013 to 18.6% (95%CI 18.3-19.0) in 2019. There was a reduction in use in the last two weeks, from 97% (95%CI 96.6-97.4) in 2013 to 86.1% (95%CI 85.4-86.8) in 2019, which was observed for most Federation Units. In 2019, the demand for care was greater among women, the elderly, those with high schooling, individuals with health insurance and poor self-rated health. They obtained greater access to health services in the fifteen days prior to the survey: men, children or adolescents up to 17 years of age, people with health insurance and poor health self-assessment. CONCLUSION The demand for health services has grown and reduced access in the last 15 days between 2013 and 2019. These differences may have been exacerbated by the austerity measures implemented in the country.
Expressive Motion Synthesis for Robot Actors in Robot Theatre

Lately, personal and entertainment robotics are becoming more and more common. In this thesis, the application of entertainment robots in the context of a Robot Theatre is studied. Specifically, the thesis focuses on the synthesis of expressive movements or animations for the robot performers (Robot Actors). The novel paradigm emerged from computer animation is to represent the motion data as a set of signals. Thus, preprogrammed motion data can be quickly modified using common signal processing techniques such as multiresolution filtering and spectral analysis. However, manual adjustments of the filtering and spectral methods parameters, and good artistic skills are still required to obtain the desired expressions in the resulting animation. Music contains timing, timbre and rhythm information which humans can translate into affect, and express the affect through movement dynamics, such as in dancing. Music data is then assumed to contain affective information which can be expressed in the movements of a robot. In this thesis, music data is used as input signal to generate motion data (Dance) and to modify a sequence of pre-programmed motion data (Scenario) for a custom-made Lynxmotion robot and a KHR-1 robot, respectively. The music data in MIDI format is parsed for timing and melodic information, which are then mapped to joint angle values. Surveys were done to validate the usefulness and contribution of music signals to add expressiveness to the movements of a robot for the Robot Theatre application.
Analysis of airgap flux, current and vibration signals as a function of the combination of static and dynamic airgap eccentricity in 3-phase induction motors

This paper provides new information for the online diagnosis of airgap eccentricity in three-phase induction motors. A new theoretical analysis of the interaction between harmonic field components due to static and dynamic rotor eccentricity which previous research has not considered is put forward. The resultant harmonic current components produced in the supply current which are highlighted by the analysis are found to exist experimentally and indeed shown to be a function of the combined effect of both dynamic and static eccentricity. Further vibration analysis is put forward to identify which particular form of rotor eccentricity is dominant; hence illustrating how faults can be identified in a motor using condition monitoring techniques.
Using geometric and semantic attributes for semi-automated tag identification in OpenStreetMap data

OpenStreetMap is one of the successful volunteered geographical information projects. Participants contribute to this crowdsourced project by adding geometric and semantic data. However, both missing geometric and semantic data still cause completeness problems. In this paper, a semi-automated approach is suggested to identify the values of leisure tag of polygon features. The approach uses geometric (rectangularity, density, area, and distances to bus stop and shop) and semantic (amenity) data and estimates the key values using random forest classifier. In short, the results show that tag identification was conducted in three districts of Ankara with f-scores 78%, 86%, and 87%.
Small-signal modeling of average current-mode control

A recently proposed average current-mode control is analyzed. A complete small-signal model for the control scheme is developed. The model is accurate up to half the switching frequency. By closing the current loop, a flat control-to-inductor current transfer function, up to half the switching frequency, can be achieved. This control scheme enables the converter to behave as an ideal current source. The subharmonic oscillation, as frequently reported in peak current-mode control, also exists in this control. This subharmonic oscillation can be eliminated by choosing a proper gain of the compensation network in the current loop. Model predictions are confirmed experimentally. <<ETX>>
Multi-modal detection and parameter-based tracking of road borders with a laser scanner

This paper treats an important problem concerning driver assistance systems: the detection and tracking of road borders. The detection of the road boarders are created from the signals of a laser scanner system. Two different information can be taken from the laser signal: range and reflectivity. The range signal delivers the road edges at the basis of single scans. In opposite to that, to detect edges in the reflectivity, the reflectivity signals are arranged as images and a special image processing algorithm is developed. The fusion and tracking of this information is performed using an Extended Kalman filter where a circular curve is used as movement model.
A three phase motor drive using IGBTs and constant V/F speed control with slip regulation

This paper deals with the design and analysis of a three phase induction motor drive using IGBTs at the inverter power stage. An analysis of the steady state equivalent circuit model of an induction motor is presented to establish the equations that justify the use of a constant Volts/Hertz speed control. In order to compensate the voltage at low frequencies it is necessary to obtain the equivalent circuit model impedances by means of laboratory tests. The paper also describes the design of the control stage and presents the results obtained from the motor operating at different frequencies.
Three-dimensional printing in the construction industry: A review

Abstract Three-dimensional (3D) printing has long been used in the manufacturing sector as a way to automate, accelerate production and reduce waste materials. By using this technology, it is possible to build a wide variety of objects if the necessary specifications are provided to the printer and no problems are presented by the limited range of materials available. With 3D printing becoming cheaper, more reliable and, as a result, more prevalent in the world at large, it may soon make inroads into the construction industry. Little is known, however, of 3D printing in current use in the construction industry and its potential for the future, and this paper seeks to investigate this situation by providing a review of the relevant literature. In doing this, the three main 3D printing methods of contour crafting, concrete printing and D-shape 3D printing are described, which, as opposed to the traditional construction method of cutting materials down to size, deliver only what is needed for completion, vastly reducing waste. The paper also identifies 3D printing's potential to enable buildings to be constructed many times faster and with significantly reduced labour costs. In addition, it is clear that construction 3D printing can allow the further inclusion of building information modelling into the construction process, thus streamlining and improving the scheduling requirements of a project. However, the current 3D printing processes are known to be costly, unsuited to large-scale products and conventional design approaches and have a very limited range of materials that can be used. Moreover, the only successful examples of construction in action to date have occurred in controlled laboratory environments and, as real world trials have yet to be completed, it is yet to be seen whether it can be equally proficient in practical situations.
Mental Health in the Elderly during the Pandemic in Indonesia

Background: The pandemic period due to the spread of the covid virus has had a tremendous impact on daily life. The psychological aspect is one of the interesting topics to discuss the impact of covid 19. The elderly are one of the most vulnerable to experiencing its effects, especially on their mental health. Methods : This study aims to describe the mental health condition of the elderly and how it correlates with death anxiety. A total of 64 elderly consisting of 60-82 years participated in this study. Data collection data using MHI-5 and Death anxiety scale. Data analysis using Pearson's correlation. Conclusions : The results showed that death anxiety with psychological distress has a significant positive correlation of 0.335 with p-value 0.001. It is also known that the results of the correlation of the two aspects of mental health, namely psychological distress and psychological well-being, have a positive Pearson's correlation value that is not significant, namely 0.198 with p-value > 0.001. The implications and limitations of these findings are also discussed.
Novel Wavelet-Fuzzy Based Indirect Field Oriented Control of Induction Motor Drives

This paper presents a wavelet-fuzzy based controller for indirect field oriented control of three-phase induction motor drives. The discrete wavelet transform is used to decompose the error between the actual speed and the command speed of the induction motor drive into different frequency components. The transformed error coefficients along with the scaling gains are used for generating the control component of the motor. Self-tuning fuzzy logic is used for online tuning of the scaling gains of the controller. The proposed controller has the ability to meet the speed tracking requirements in the closed loop system. The complete indirect field oriented control scheme incorporating the proposed wavelet-fuzzy based controller is investigated theoretically and simulated under various dynamic operating conditions. The simulation results are compared with a conventional proportional integral controller and a fuzzy based controller. The speed control scheme incorporating the proposed controller is implemented in real time using a digital processor control board. Simulation and experimental results validate the effectiveness of the proposed controller.
Mutual coupling in finite coplanar rectangular waveguide arrays

Mutual admittance expressions are given for all possible combinations of mode coupling in an array of identical collinear rectangular waveguides opening into an infinite ground plane. Specific results are presented for the worst case of E-plane coupling between identical square waveguide to show that significant high-order mode excitation can occur. Some of these modes are a source of crosspolarisation, making mutual coupling important to the prediction of the crosspolar pattern of a rectangular waveguide array.
Wavelet Transform-based Higher-order Statistics for Fault Diagnosis in Rolling Element Bearings:

Signal processing plays a pivotal role in fault diagnostics of mechanical systems. An approach, viz. wavelet transform-based higher-order statistics, was developed in this paper for fault diagnosis in rolling element bearings. In the approach, wavelet transform (discrete wavelet and wavelet packet transform) was introduced into a fourth-order statistic, kurtosis. Thereinto, discrete wavelet transform-based kurtosis (DWTK) was applied to signals to get a higher resolution in low-frequency bands1 on the other hand, wavelet packet transform-based kurtosis (WPTK) was applied to obtain a relatively high resolution in high-frequency bands in comparison with the DWTK. DWTK, WPTK and wavelet transform-based kurtosis (WTK) curves were introduced to calibrate the in-field signals in comparison with the benchmark signals, whereby the non-stationary transients and singularity in the vibration signals attributed to damage were detected. WTK curves of vibration signals collected from bearing with damage of different se.
Screening for potential strain to produce bioprotein from cheaper carbon source

Enough production of food and fodder are essential for sustainability. In times to come, the population of developed countries might be stabilized, but it will keep on increasing, in developing countries, at the rate of average four per cent. This will warrant utilization of certain carbon rich sources, which are easily available and can effortlessly be converted into food and fodder, rich in protein and other essential nutrients. The production of bioproteins (proteins derived from micro-organisms) by fermentation of cheaper carbon source is one of the most promising breakthrough of biotechnological innovations, which will certainly increase the availability of high quality affordable proteins in the world and reduce dependence on animals. Due to the increasing demand for bioproteins, the efficient strains, substrate and method must be used for high yield product. In this study, we have made prudent efforts to produce maximum quantity of bioprotein by liquid state bioconversion of wheat flour - a cheaper carbon source having high nutritional value, high carbohydrate percentage and easily available in Malaysia. Screening of five different microorganisms - Aspergillus niger, Phanerochaete chrysosporium, Saccharomyces cerevisiae, Mucor hiemalis and Thricoderma harzianum - was done with fixed process conditions. Bioconversion was done in a 500 ml Erlenmeyer flask having 100 ml of wheat flour with known concentration of 2% (w/v) at a temperature of 27 0 C, agitation of 150 rpm with 2% inoculum (10 6 spores/ml). Biomass production was recorded every day for six days and the protein content was also determined every day. From the observed results, Mucor hiemalis was found to be as the most potential strain with biomass of about 11.4 g/L on the fourth day of treatment. With this promising result, the amount of bioproteins could be further increased by optimizing process factors. This study may provide a better alternative in agricultural products by converting cheaper carbon source to valuable and quality product bioprotein, which can be used as supplement and additive in the animal feed as well as in chemical and pharmaceutical industries.
A novel instantaneous power control strategy and analytic model for integrated rectifier/inverter systems

This paper is concerned with the design and implementation of an integrated pulse width modulation (PWM) rectifier/inverter for three-phase induction motor drives. Two identical PWM converters are used to serve as power regulator with unity power factor and servo motor drive using field-oriented control, respectively. A new input-output instantaneous power balancing approach is proposed to improve the dynamic response of input power regulation during output load change in order to minimize the DC-link capacitance. By using the synchronous rotating-frame current regulators, both the input and output currents of the integrated system are characterized with fast current response and low harmonic distortion. The effects of the dynamic response using different input power control methods are compared and the systematic design and analysis of the proposed method are also presented. Theoretical results of the analysis are verified experimentally.
Off-line wafer level reliability control: unique measurement method to monitor the lifetime indicator of gate oxide validated within bipolar/CMOS/DMOS technology

We have recently published a paper on a new rapid method for the determination of the lifetime of the gate oxide involved in a Bipolar/CMOS/DMOS technology (BCD). Because this previous method was based on a current measurement with gate voltage as a parameter needing several stress voltages, it was applied only by lot sampling. Thus, we tried to find an indicator in order to monitor the gate oxide lifetime during the wafer level parametric test and involving only one measurement of the device on each wafer test cell. Using the Weibull law and Crook model, combined with our recent model, we have developed a new test method needing only one electrical measurement of MOS capacitor to monitor the quality of the gate oxide. Based also on a current measurement, the parameter is the lifetime indicator of the gate oxide. From the analysis of several wafers, we gave evidence of the possibility to detect a low performance wafer, which corresponds to the infantile failure on the Weibull plot. In order to insert this new method in the BCD parametric program, a parametric flowchart was established. This type of measurement is an important challenges, because the actual measurements, breakdown charge, Qbd, and breakdown electric field, Ebd, at parametric level and Ebd and interface states density, Dit during the process cannot guarantee the gate oxide lifetime all along fabrication process. This indicator measurement is the only one, which predicts the lifetime decrease.
Mesquite (Prosopis Juliflora) Pod Meal to Goats Feed: Ruminal Parameters and Molecular Diversity of Ruminal Bacteria and Methanogenic Archaea

— This study aimed to evaluate the effects of mesquite (Prosopis juliflora) pod meal (MPM) replacing corn in concentrate feeds on ruminal parameters and microbial diversity. MPM was used in 0.0, 33.3, 66.7 and 100% levels in isonitrogenous diets, and elephant grass (Pennisetum purpureum) silage as forage. For the experiment we divided the animals into 4x4 Latin square. The intake of dry matter, crude protein, neutral detergent fiber and acid detergent fiber were not affected by the MPM levels. The pH varied linearly, increasing according to the levels of MPM and remained at adequate range between 6.32 and 6.85 for 8 hours after feeding. The ammonia concentration showed a peak of 14.01 mmol L -1 2 hours after the morning feeding and the acetate, propionate and butyrate concentrations did not show any effect. The genetic diversity of bacteria and archaea was determined by PCR-DGGE. The analyses showed variations in banding pattern, indicating changes in the populations studied as a result of the treatments and a reduction in methanogenic after the addition of up to 66.7% of MPM. MPM can be used at levels of 33.3% and 66.7% of corn replacing without reducing the nutrients intake. The reduction of archaea has a possible contribution in reducing methanogenesis, since it also reduces the acetate:propionate ratio. Mesquite is a source of food for goats in small holdings, with potential reduction in methanogenesis.
Cut-off frequency and transit time analysis in short geometry polysilicon thin-film transistors

An accurate model for the drain characteristics, transconductance, cut-off frequency and transit time of a short geometry polysilicon thin film transistor (poly-Si TFT) is presented. An accurate threshold voltage and field dependent mobility are the key parameters in determining the above-threshold characteristics. The current-voltage characteristics of the device show an excellent agreement with experimental results. The transconductance for both linear and saturation regions is calculated and its variation with channel length, drain and gate voltages is studied. The total gate capacitance including the geometric capacitance and the fringing capacitance is also evaluated and simple closed form expressions for the cut-off frequency and transit time are obtained. A high cut-off frequency is achieved, which is important in realizing the device for millimetre and microwave frequency applications.
