Antioxidant Capacity, Fatty Acid Profile and Volatile Components of the Onopordum Anatolicum and Onopordum Heteracanthum Species Seeds Grown in Van, Turkey

: The crude oil contents, total phenolic contents, volatile components and antioxidant activities of Onopordum anatolicum and Onopordum heteracanthum species seeds were investigated. In addition, the fatty acid profile, tocopherol contents, peroxide values, free fatty acidity and color values of the oils obtained from species seeds were determined. The oil contents of O. anatolicum and O. heteracanthum species seeds were found to be 15.84% and 12.54%, respectively. Total phenolic contents were found as 18554 and 13015 mg-GAE kg -1 . DPPH (% inhibition) values in the studied seeds and BHT were determined as 84.41, 66.73, and 86.92% and ABTS values were determined as 121.18, 46.90, and 123.78 mmol Trolox eq. g -1 . Linoleic acid (49.38 and 38.09%) and oleic acid (30.04 and 22.07%) were the most abundant fatty acids in the oil from seeds. In addition, a significant amount of α-tocopherol (1066.99 mg kg -1 ) was detected in O. anatolicum seed oil. Furthermore, 17 volatile compounds were detected in different amounts of each in the seeds of the species. In the light of all these findings, it was concluded that the seeds of O. anatolicum and O. heteracanthum could be appreciated as alternative oil raw materials, and used as natural antioxidant and polyunsaturated fatty acids sources in the formulation in functional foods.
Efficient robust geotechnical design of drilled shafts in clay using a spreadsheet

Abstract This paper presents an efficient robust geotechnical design (RGD) approach that considers performance requirements, design robustness, and cost efficiency simultaneously. In this paper, design robustness is measured via the variation in the performance function of concern that can be evaluated using reliability analysis. Furthermore, the performance requirements of the system are also evaluated using reliability analysis. Thus, the evaluation of design robustness and the evaluation of performance requirements share common computational steps, referred to herein as computational coupling. This coupling for computational efficiency is a significant feature of the proposed RGD approach. Within the framework of the proposed RGD approach, design robustness, cost efficiency, and performance requirements can be considered simultaneously by means of multiobjective optimization. Furthermore, a practical and efficient procedure is developed for such optimization using a feature resident in a popular spread.
Vocabularies for Publishing Research Data

ABSTRACT Research data are essential for the development of science, and one of the issues to be addressed is its organization and representation. Based on these basic concepts of Information Science, we seek to explore the Data Catalog Vocabulary (DCAT) and the vocabularies used by it in the context of research data publication. We assert that the use of metadata vocabularies to represent research data is necessary to improve access, findability, interoperability, and the retrieval of datasets. We verify that DCAT enables the standardization of catalogs and datasets through specific terms for this purpose, presenting itself as an adequate vocabulary to represent the research data.

The following asks: What are the major areas of COVID-19 rapid research output conducted in Canada during the first five and half months of 2020, and how can the results of this analysis inform future accelerated research efforts toward an effective response to infectious disease emergencies? The results suggest that infection prevention, epidemiology, therapeutics, and public health strategies were among the top-producing research areas in Canada during the onset of the pandemic. Moreover, the analysis reflects gaps in the literature addressing diagnostics and vaccine development.
Methods for contingency screening and ranking for voltage stability analysis of power systems

The comparison of performance of four methods for contingency screening and ranking for voltage stability analysis is presented. Three of the methods are existing methods, while a new method is proposed. The performance of all the methods is carried out by comparing with full solutions using a continuation power flow. It is shown that the newly proposed method has the best performance in terms of accuracy and computation time. All the methods are evaluated using a 234-bus system. Additional results using the best performing method are included for a 901-bus power system.
A low-noise, low-power CMOS SOI readout front-end for silicon detector leakage current compensation with capability

A low-noise, low-power CMOS semiconductor on insulator (SOI) readout front-end aiming at dc coupling to silicon radiation detectors is presented in this paper. It is able to compensate the leakage current of detectors within a wide range up to 10 /spl mu/A. While the presented solution does not significantly deteriorate the amplifier noise performance it complies with demands for low-noise readout system for silicon detectors. This front-end system includes a charge-sensitive amplifier, a semi-Gaussian CR-RC shaping amplifier and an output buffer. It has been simulated and implemented in a CMOS SOI-SIMOX process. For no leakage current, an input referred equivalent noise charge (ENC) of 426 electrons (rms) for 0 pF of detector capacitance with a noise slope of 40 electrons/pF, a peaking time of 50 ns, and a conversion gain of 23.4 mV/fC have been obtained.
Comparative Metabolomics Analysis and Radical Scavenging Activity of Saraca asoca (Roxb.) de Wilde Flowers in Different Stages of Maturity

The flower extracts of Saraca asoca were evaluated in their three different phenological stages of flowering [bud (S1), mature (S2) and senescent (S3)] in terms of chemical composition and antioxidant activity. The GC/MS based fingerprinting led to identification of 85 metabolites, including 9 amino acids, 20 organic acids, 7 fatty acids, 20 sugar and sugar acids, 8 sugar alcohols, 13 phenols and phenolic acids and 8 others compounds. The three flowering stages showed prominent changes in their metabolite profile during the process of maturation of the flowering stages from bud to mature to senescence stages determined via GC/MS based metabolomics and chemometric approaches. The amounts and composition of metabolites in each stage showed statistically significant differences, which were reflected in their antioxidant capacities. The three phenological stages showed antioxidant activities in a dose dependent manner, but the senescent stage showed highest superoxide radical scavenging activity (IC50 = 65.17 ± 2.647 mg/ml) and metal chelating effect (6.65 ± 0.331 mg/ml) in agreement with their high content of phenolic acids. These differences were strongly reproduced in the chemometric analyses (PCA, PLS-DA and s-PLS-DA), identifying the most distinctive features of the three flowering stages. This study might be beneficial to select the most potent flowering stage for incorporation in functional food.
Reducing tardy jobs by integrating process planning and scheduling functions

This paper presents a dynamic approach to reduce tardy jobs through the integration of process planning and scheduling in a batch-manufacturing environment. The developed method aims at re-generating a schedule with fewer tardy jobs, step by step, by exploring the process plan solution space of the tardy jobs. The integrated system comprises a process planning module, a scheduling module, and an integrator module. The process planning module employs an optimisation approach in which the entire plan solution space is first generated and a search algorithm is then used to find the optimal plan, while the scheduling module is based on commonly used heuristics. Based on the job tardiness information of the generated schedule, the integrator module automatically issues a modification order to the process plan solution space of the tardy jobs. The process planning and scheduling modules are then re-run to generate a new plan/schedule solution. Through this iterative process, a satisfactory schedule can be gradually achieved. The uniqueness of this approach is characterised by the flexibility of the process planning strategy, which makes full use of the plan solution space intuitively to achieve a satisfactory schedule. Several examples are presented to confirm the efficacy and the effectiveness of the developed integration system.
An improved termination structure for silicon radiation detectors with all-P-type multiguard and cut-line implants

A junction termination structure for silicon radiation detectors is investigated, featuring all-p-type multiguard and scribe-line implants, with metal field-plates providing complete coverage of the oxide upper surface above nonimplanted regions. The sensitive interface between oxide and n-type substrate is thus electrostatically screened from the external environment, resulting in improved long-term stability of the device and excellent insensitivity to ambient conditions both before and after X-ray and neutron irradiations. Careful design of the multiguard layout enables high-voltage operation to be achieved. With respect to a previously proposed structure, the adoption of alternate outward and inward field plates between adjacent rings allows a significant improvement in the voltage handling capability.
Development and implementation of a system to measure the response of quartz crystal resonator based gas sensors using a field-programmable gate array

The development of gas sensors based on quartz crystal resonators requires the use of a frequency counter to measure the sensor response. However, commercial frequency counters have at most two channels, and in odour sensory systems (electronic noses), arrays of at least eight sensors are used. Furthermore, it is also desirable that the signal processing and data analysis stage can be included in the same system. A field-programmable gate array (FPGA) can provide a solution to these kinds of problems. This work involves the development of a system to measure the response of quartz crystal resonators, which is implemented using a high resolution frequency counter using an FPGA capable of processing and storing the data in 32-bit registers. Data transfer and acquisition were performed using a microcontroller. The virtual instrumentation software LabVIEW was used for the sensor response display and data storage in a computer. A frequency range from 0 Hz to 100 MHz with a resolution and stability of 1 Hz was achieved using a timebase of 1 s. Tests were performed using gas sensors to obtain real data. The system was escalated to four channels, verifying that it behaves in a correct and stable way.

Bioethanol Combustion in an Industrial Gas Turbine Combustor: Simulations and Experiments

Combustion tests with bioethanol and diesel as a reference have been performed in OPRA's 2 MWe class OP16 gas turbine combustor. The main purposes of this work are to investigate the combustion quality of ethanol with respect to diesel and to validate the developed CFD model for ethanol spray combustion. The experimental investigation has been conducted in a modified OP16 gas turbine combustor, which is a reverse-flow tubular combustor of the diffusion type. Bioethanol and diesel burning experiments have been performed at atmospheric pressure with a thermal input ranging from 29 to 59 kW. Exhaust gas temperature and emissions (CO, CO2, O2, NOx) were measured at various fuel flow rates while keeping the air flow rate and air temperature constant. In addition, the temperature profile of the combustor liner has been determined by applying thermochromic paint. CFD simulations have been performed with ethanol for five different operating conditions using ANSYS FLUENT. The simulations are based on a 3D RANS code. Fuel droplets representing the fuel spray are tracked throughout the domain while they interact with the gas phase. A liner temperature measurement has been used to account for heat transfer through the flame tube wall. Detailed combustion chemistry is included by using the steady laminar flamelet model. Comparison between diesel and bioethanol burning tests show similar CO emissions, but NOx concentrations are lower for bioethanol. The CFD results for CO2 and O2 are in good agreement, proving the overall integrity of the model. NOx concentrations were found to be in fair agreement, but the model failed to predict CO levels in the exhaust gas. Simulations of the fuel spray suggest that some liner wetting might have occurred. However, this finding could not be clearly confirmed by the test data
Width effects on downward flame spread over poly(methyl methacrylate) sheets

The experiments of downward flame spread over poly(methyl methacrylate) sheets with different dimensions were conducted in this study. In comparison with flame spread over samples under infinite width condition, lateral air entrainment shows significant influence on downward flame spread of finite width. The characteristic angles, defined as those produced on sample residues in a steady-state stage, are constant for different dimensions. Based on the characteristic angles and with reasonable assumptions, a three-dimensional theoretical model is proposed to illustrate the experimental results. Width effects on downward flame spread over thicker samples are more obvious and they fade away with gradual increase in width. Moreover, the heat flux penetrating through the solid surface at the front of the pyrolysis region is higher than that in the two-dimensional case. The flame height correlates well with mass loss rate as an exponential function with a mean power value of 0.79.
Wireless energy transfer-based transceiver systems for power and/or high-data rate transmission through thick metal walls using sheet-like waveguides

The potential use of sheet-like waveguide-based wireless energy transfer systems for a two-way power and/or high-data rate transmission–reception through thick metal walls is investigated. The proposed system utilises the near-field evanescent wave concept to transmit energy and/or data. Compared with wireless energy transfer devices based on magnetic resonance coupling, the transmission efficiency of the investigated method is not affected by the shielding offered by metal sheets. For the investigation, a 150 × 150 mm2 sheet-like waveguide transmitter and a cylindrical wave-cavity receiver were designed. The receiver achieved a transfer efficiency of −3.76 dB, while transmitting power through galvanised iron sheets. The prime objective of this investigation was to sustain the power and/or data transfer efficiency despite the variation of the obstructing metal wall thicknesses from 1.5 to 22.5 mm. The proposed system was designed to operate at 25 MHz, enabling 50 Mbit/s data transfer using a function generator.
Cost-effectiveness of Routine Provider-Initiated Testing and Counseling for Children With Undiagnosed HIV in South Africa

Abstract Background We compared the cost-effectiveness of pediatric provider–initiated HIV testing and counseling (PITC) vs no PITC in a range of clinical care settings in South Africa. Methods We used the Cost-Effectiveness of Preventing AIDS Complications Pediatric model to simulate a cohort of children, aged 2–10 years, presenting for care in 4 settings (outpatient, malnutrition, inpatient, tuberculosis clinic) with varying prevalence of undiagnosed HIV (1.0%, 15.0%, 17.5%, 50.0%, respectively). We compared “PITC” (routine testing offered to all patients; 97% acceptance and 71% linkage to care after HIV diagnosis) with no PITC. Model outcomes included life expectancy, lifetime costs, and incremental cost-effectiveness ratios (ICERs) from the health care system perspective and the proportion of children with HIV (CWH) diagnosed, on antiretroviral therapy (ART), and virally suppressed. We assumed a threshold of $3200/year of life saved (YLS) to determine cost-effectiveness. Sensitivity analyses varied the age distribution of children seeking care and costs for PITC, HIV care, and ART. Results PITC improved the proportion of CWH diagnosed (45.2% to 83.2%), on ART (40.8% to 80.4%), and virally suppressed (32.6% to 63.7%) at 1 year in all settings. PITC increased life expectancy by 0.1–0.7 years for children seeking care (including those with and without HIV). In all settings, the ICER of PITC vs no PITC was very similar, ranging from $710 to $1240/YLS. PITC remained cost-effective unless undiagnosed HIV prevalence was <0.2%. Conclusions Routine testing improves HIV clinical outcomes and is cost-effective in South Africa if the prevalence of undiagnosed HIV among children exceeds 0.2%. These findings support current recommendations for PITC in outpatient, inpatient, tuberculosis, and malnutrition clinical settings.
Estimation of litter input in hemi-boreal forests with drained organic soils for improvement of GHG inventories

Assessments of net greenhouse gas (GHG) emissions in forest land with drained organic soils conducted within the scope of National GHG inventories requires reliable data on litter production and carbon (C) input to soil information. To estimate C input through tree above-ground litter, sampling of above-ground litter was done in 36 research sites in Latvia representing typical forests with drained organic soils in hemiboreal region. To estimate C input through tree below-ground litter and litter from ground vegetation, modelling approach based on literature review and data on characteristics of forest stands with drained organic soils in Latvia provided by National Forest Inventory (NFI) was used. The study highlighted dependence of C input to soil through litter production from the stand characteristics and thus significant differences in the C input with litter between young and middle age stands. The study also proves that drained organic soils in middle age forests dominated by Silver birch, Scots pine and Norway spruce may not be the source of net GHG emissions due to offset by C input through litter production. However, there is still high uncertainty of C input with tree below-ground litter and ground vegetation, particularly, mosses, herbs and grasses which may have crucial role in C balance in forests with drained organic soils. Key words: forests, drained organic soils, litter production, carbon input, National GHG inventory
A High Performance Baseband Testing Instrument for Access Network System: A PXI-Based Approach

High performance network over coax (HINOC) is a recently proposed technology which plays a central role in the integration of telecommunications networks, cable TV networks and the Internet. But there still is a lack of comprehensive testing equipment designed for it yet, especially in baseband signal testing area. In this paper, we designed a high performance baseband signal transmitter and analyzer for HINOC system test. The system is implemented as hardware and software co-design architecture. Both of the baseband signal transmitter and analyzer have passed a series of rigorous tests, which demonstrates that the whole system meets the HINOC test specification and can provide great assistance for follow-up HINOC research.
