Taxonomical study on the Architectonicidae collected by the Marion Dufresne (MD55) expedition to SE Brazil

Some of the deep-water molluscs collected during the Marion Dufresne (MD55) expedition off SE Brazil have been studied in recent papers. The present work focuses on the heterobranch family Architectonicidae. Four species have their occurrence expanded to/in the SW Atlantic (new records in parenthesis): Psilaxis clertoni Tenório, Barros, Francisco & Silva, 2011 (off Cabo Frio, Rio de Janeiro, 610 m); Solatisonax rudigerbieleri Tenório, Barros, Francisco & Silva, 2011 (Canopus Bank, off Fortaleza, Ceará state, 260 m; off Cabo Frio, Rio de Janeiro, 610 m); Spirolaxis centrifuga (Monterosato, 1890) (off Linhares, Espírito Santo, 340-360 m); Spirolaxis cf. lamellifer (Rehder, 1935) (off Linhares, Espírito Santo, 640 m depth and off Cabo Frio, Rio de Janeiro, 610 m). Moreover, we describe herein a new architectonicid species, namely Pseudotorinia phorcysi spec. nov., collected off Cabo Frio, Rio de Janeiro state, 430-450 m. Its diagnostic features are: a strong beaded sculpture, angular outline and prominent peripheral keel formed by a strong beaded spiral rib and a lower, weaker rib, with fine axial growth lines between them.
A Trajectory Piecewise-Linear Approach to Nonlinear Model Order Reduction of Wind Farms

This paper presents a method to develop computationally efficient dynamic model of a wind farm suitable for large disturbance simulation. The method based on a trajectory piecewise linear approximation uses single and multiple training trajectory to develop a nonlinear reduced order model. Simulation results using a small demonstration wind farm system and a large practical wind farm system are discussed to demonstrate the effectiveness of the model in capturing dynamic behavior of wind farm following large disturbances.
Which properties of the vascular architecture are reflected by dynamic contrast-enhanced ultrasound imaging of dispersion and wash-in rate? A comparison with acoustic angiography

Tumor growth requires angiogenesis and neovascularization, resulting in the formation of microvessels which differ in their morphology from those of healthy tissue. These vascular abnormalities result in altered blood flow dynamics, which can be assessed by dynamic contrast-enhanced ultrasound (DCE-US). Two distinct approaches are typically employed in DCE-US: the assessment of either perfusion or dispersion parameters from the measured time intensity curves. In this paper, we look at longitudinal trends of wash-in-rate (WIR), a perfusion parameter, and correlation coefficient, a dispersion parameter, in 3 fibrosarcoma xenograft models. We compare them to the microvascular density (MVD) extracted from acoustic angiography (AA), a high resolution technique enabling the delineation of microvessels. We also compare spatial parameter distributions acquired with both imaging modalities. The performed analysis indicates that WIR reflects MVD, while no microvascular parameter that reflects the correlation coefficient has been identified. We hypothesize that the correlation coefficient reflects properties of smaller vessels than those visible with AA.
What Drove the 2003-2006 House Price Boom and Subsequent Collapse? Disentangling Competing Explanations

Ten years after the financial crisis, the central question of what explains the rise and fall in house prices remains unresolved. We provide a unified framework to examine four excess credit supply variables and three speculation variables that have been proposed in the literature. Credit supply variables, particularly subprime share and worse originator share, strongly relate to future zip code level house price changes in the boom and bust, whereas none of the speculation variables consistently relate to house prices within MSAs. Pre-trends, supply elasticity, and depressed areas suggest these relations are not driven by lenders anticipating house price growth.
Tadpole of Leptopelis ragazzii (Boulenger, 1896), Shoa Forest Tree Frog (Anura, Arthroleptidae)

The tadpole of poorly studied Leptopelisragazzii (Boulenger, 1896), a high-altitude tree frog species from the Ethiopian highlands, is described for the first time and compared with closely related sympatric species – L.gramineus (Boulenger, 1898) and L.vannutellii (Boulenger, 1898).
Teaching integrity in the public sector: Evaluating and reporting anti-corruption commissions’ education function

Australia’s state-based public sector standing anti-corruption commissions each have an education function. The function is underpinned by a largely unquestioned assumption that integrity education will reduce levels of misconduct and corruption in the public sector. This study explores how these commissions undertake evaluations and publicly report on the effectiveness of their education events to demonstrate a contribution to this purpose. It acknowledges that well-designed and executed education events may deliver public value outcomes, but finds that the evaluative and reporting approaches used by commissions are insufficient to reliably demonstrate whether or not the function actually achieves this purpose. The dominance of exposure-as-success attendance statistics revealed in this study is particularly concerning as they offer no insights that are directly relevant to this purpose. Consistent with the findings of previous studies, there is also a heavy reliance on reaction-based satisfaction surveys that primarily reflect participants’ enjoyment of an education event, but do not provide meaningful evidence of learning, application of learning, organizational impact, or the overall delivery of public value. As such, it is argued that commissions need to transition from largely superficial appraisals to more robust and strategic assessments that measure actual attitudinal and behavioral change in the public sector. This study also raises questions of broader relevance to the evaluation of other types of workplace education, particularly that requiring affective and behavioral learning.
Blue light photoreceptors are required for the stability and function of a resistance protein mediating viral defense in Arabidopsis

This light-perciving ability of plants requires the activities of proteins termed photoreceptors. In addition to various growth and developmental processes, light also plays a role in plant defense against pathogens and is required for activation of several defense genes and regulation of the cell death response. However, the molecular or biochemical basis of light modulated regulation of defense signaling is largely unclear. We demonstrate a direct role for blue-light photoreceptors in resistance (R) protein-mediated plant defense against Turnip Crinkle Virus (TCV) in Arabidopsis. The blue-light photoreceptors, cryptochrome (CRY) 2 and phototropin (PHOT) 2, are specifically required for maintaining the stability of the R protein HRT, and thereby resistance to TCV. Exogenous application of the phytohormone salicylic acid elevates HRT levels in phot2 but not in cry2 background. These data indicate that CRY2 and PHOT2 function distinctly in maintaining post-transcriptional stability of HRT. HRT-mediated resistance is also dependent on CRY1 and PHOT1 proteins, but these do not contribute to the stability of HRT. HRT interacts with the CRY2/PHOT2-interacting protein COP1, a E3 ubiquitin ligase. Exogenous application of a proteasome inhibitor prevents blue-light-dependent degradation of HRT, suggesting that HRT is degraded via the 26S proteasome. These and the fact that PHOT2 interacts directly with the R protein RPS2 suggest that blue-light photoreceptors might be involved in regulation and/or signaling mediated by several R proteins.
In Vitro Evaluation of Free Radical Scavenging, Fe2+ and SNP-Induced Lipid Peroxidation (Rat Brain) Activities of Methanolic Extracts from Three (3) Northern Nigerian Plants Leaf

Over the years research findings have shown that free radicals are the basis for many diseases. This study sought to investigate the free radical scavenging and inhibition of lipid peroxidation activities of some three Northern Nigerian plant leaf; Boswellia dalzielii Hutch. (Burseraceae) (BDL), Detarium microcarpum Guill. and Perr. (DML), and Daniellia oliveiri (Rolfe) Hutch. & Dalz (DOL). The study investigated both qualitative and quantitative phytochemical screening, free radical scavenging activities of 1, 1-diphenyl–2-picrylhydrazyl DPPH, total antioxidant capacity ABTS, hydroxyl, reducing property and inhibition of lipid peroxidation. All the seven phytochemicals screened were all present in both BDL and DML plant extracts but saponins and glycosides were absent in DOL plant leaf. The result revealed that BDL methanolic extract had the highest total flavonoid and phenolic content while BDL methanolic extract had the highest alkaloid content. DOL methanolic extract had the least content in all the 3 phytochemicals quantified. BDL methanolic extract had the highest free radical scavenging activity in 1, 1-diphenyl–2-picrylhydrazyl (DPPH), Hydroxyl and reducing power assays. While DML methanolic extract, had the highest free radical scavenging ability in 2, 2-azino-bis(3-ethylbenzazoline-6-sulphonic acid (TEAC) assays. The IC 50 of BDL extract (12.37 mg/mL) was not significantly different (p > 0.05) from DML extract (10.39 mg/mL) in the Fe 2+ -induced lipid peroxidation assay. While, the IC 50 of DML extract (14.83 mg/mL) was significantly higher (p < 0.05) than the BDL extract (19.92 mg/mL) in the SNP-induced lipid peroxidation. The DOL extract had the least scavenging and peroxidative inhibitory activity in all the assays carried out. We therefore concluded that the synergistic free radical scavenging activities and inhibition of lipid peroxidation of the three plants studied (especially, BDL and DML), provides a biochemical rationale for their usage as a medicinal plant.

It can be connected with any smart device or personal computer through a Bluetooth link, which is used for commands and measurement data exchange based on a simple protocol. The system is controlled by a high performance 8-bit microcontroller and includes four miniaturized metal oxide (MOX) sensors for odour detection, an integrated sensor for temperature and humidity measurement, and the appropriate signal conditioning circuits.
Sidelobe reduction and gain enhancement in higher order TM
 30
 and TM
 70
 mode rectangular patch antennas via partial notch loading

A partial notch loading technique for E-plane sidelobe reduction and gain enhancement of higher order TM30 and TM70 mode rectangular patch antennas is proposed. In this technique, out of phase surface current distribution regions of higher order T M m 0 ( m = 3 , 7 ) mode patch antennas are partially removed to create new radiating edges. It is shown that superposition of radiated fields of these additional radiating edges and that of unperturbed T M m 0 ( m = 3 , 7 ) mode can be used to achieve sidelobe reduction and gain enhancement in single-layer configuration. Two novel single layer, easy to fabricate higher order mode patch antennas, namely, notch loaded TM30 mode patch antenna (Antenna 1) and notch loaded TM70 mode patch antenna (Antenna 2), are presented. Antenna 1 shows a measured gain of 12.9 dBi and E-plane sidelobe levels (SLL) of −10.5 dB, whereas Antenna 2 shows a measured gain of 16 dBi and SLL of −12.8 dB. To the best of authors’ knowledge, this is the highest reported antenna gain for single-layer TM70 mode rectangular patch antenna. Due to their high gain, proposed antennas are suitable for short range point to point communication applications.
Sliding Mode Power Control of Variable Speed Wind Energy Conversion Systems

This paper addresses the problem of controlling power generation in variable speed wind energy conversion systems (VS-WECS). These systems have two operation regions depending on wind turbines tip speed ratio. They are distinguished by a minimum phase behavior in one of these regions and a nonminimum phase in the other one. A sliding mode control strategy is then proposed to ensure stability in both operation regions and to impose the ideal feedback control solution despite of model uncertainties. The proposed sliding mode control strategy presents attractive features such as robustness to parametric uncertainties of the turbine and the generator as well as to electric grid disturbances. The proposed sliding mode control approach has been simulated on a 1.5-MW three-blade wind turbine to evaluate its consistency and performance. The next step was the validation using the NREL (National Renewable Energy Laboratory) wind turbine simulator FAST (Fatigue, Aerodynamics, Structures and Turbulence code). Both simulation and validation results show that the proposed control strategy is effective in terms of power regulation. Moreover, the sliding mode approach is arranged so as to produce no chattering in the generated torque that could lead to increased mechanical stress because of strong torque variations.
An influence of workplace victimization on employees’ internet pornography addiction and organizational outcomes

Abstract The purpose of this study is to investigate if workplace victimization arouses employees’ internet pornography addiction and how it influences their job satisfaction and organizational citizenship behavior. And, this study explores if perceived organizational support can be an organizational factor moderating the relationship between workplace victimization and internet pornography addiction. For this, this study collected data from 305 employees in Korean companies through a survey method. In the results, first, the more employees suffer from workplace victimization, they are more likely to be addictive in internet pornography. Second, the more addictive employees are in internet pornography, their job satisfaction and organizational citizenship behavior decreases. Finally, when employees perceive more support provided by the organization, they are less likely to be addictive in internet pornography which is aroused by workplace victimization.
GENDER DIFFERENCE IN UNDERSTANDING AGEING AND RETIREMENT

The age-old wisdom is that “women live longer than men”. Gender difference in life expectancy is becoming a worldwide phenomenon both in developed and developing countries. The process of ageing may be viewed from the perspectives of physical, psychological, and social-economic wellbeing. We investigated gender difference in understanding ageing in relation to life expectancy, fears relating to diseases and deteriorating economic status, and perceived old age comfort and their preparedness. Data were obtained from an online survey and in-person interview of 518 respondents aged 40 years and older residing in Malaysia, which was based on a convenience sample collected from May 2015 to January 2016. Data were analysed using chi- squared tests and multinomial logistic regression. There were varying views between men and women when it came to understanding ageing in relation to life expectancy, fears of ageing, deteriorating economic status and their perception of old age comfort. Women were more optimistic about living longer compared to men but feared more the consequences of old age diseases. In spite of displaying less concern about financial preparedness, women were, however, willing to cut down expenses, while men would prefer longer working hours to ensure a comfortable retirement.

Protected Control Method for Power Conversion Interface Under Unbalanced Operating Conditions in AC/DC Hybrid Distributed Grid

The voltage source converters (VSC) are the key power interfaces between the individual ac grids and dc grids in the hybrid power system. When the ac grid is unbalanced, the grid currents are distorted and the harmonic is induced. Meanwhile, the oscillations in the active and reactive power are also increased, which may damage these interfaces. In order to ensure the safety of the converters and the grid facility, a flexible control strategy is proposed for the ac/dc hybrid grid in this paper. At first, the current harmonic for the VSC is theoretically analyzed under unbalanced conditions. Furthermore, the methods to separate the positive- and negative-sequence components of the ac grid voltages are summed up and analyzed. Based on the theoretical analysis, different protected control methods are compared. A new control method, which can flexibly control oscillations of the active and reactive power by introducing a parameter k, has been proposed. The estimation of maximum current in each phase is discussed; meanwhile, the relationship between the voltage ripple on dc link and the parameter k is given. Finally, the validity and advantages of the proposed method are verified by the simulating and experimental results.
Determination of antioxidant potential of biochemically synthesized silver nanoparticles using Aloe vera gel extract

Biosynthesis of nanoparticles by using plant extracts is presently under development. The study has been focused on the biosynthesis of silver nanoparticles (AgNPs) using aqueous extract of Aloe vera gel as well as to determine their antioxidant potential. UV-Vis spectrophotometeric analysis showed surface plasmonic resonance (SPR) band at 440 nm, which is specific for AgNPs. The Transmission Electron Microscopy (TEM) revealed that the synthesized AgNPs were spherical in shape with an average particle size of 66.6 nm. Fourier Transform Infrared Spectroscopic (FTIR) analysis of the aqueous extract before and after the synthesis of AgNPs revealed the presence of different functional groups related to phenolic and polyphenolic compounds such as tannins and flavonoids, and other metabolites like proteins, which may be responsible for the synthesis and stabilization of AgNPs. The antioxidant potential of the synthesized AGAgNPs was determined by using 2, 2 Diphenyl-1- Picryl Hydrazyl (DPPH) radical scavenging, metal chelating and reducing power assay. Antioxidant assessment showed enhanced dose dependent antioxidant potential of the synthesized AgNPs as compared to the crude extract, which can gain attention of the pharmaceutical industry for preparation of antioxidants of natural origin as the synthetic ones are suspected to be carcinogenic. Present study also supports the advantages of green method for the nanoparticles synthesis.
Efficient video object classifier using locality-enhanced support vector machines

In multimedia applications such as MPEG-4, an efficient model is required to encode and classify video objects such as human, car and building. Recently, support vector machine (SVM) has been shown to be a good classifier; however, its large computational requirement prohibited its use in real time video processing applications. In this paper, a model is proposed that enables use of SVM in video applications. This paper aims to merge multi-scale based selective encoding/classification technique and locality-enhanced support vector machine (SVM). The proposed model allows selected image scales (of interest) to be encoded and classified more accurately by complex classifier such as SVM, whilst other image scales of less significance to be encoded and classified by simpler encoder/classifier. Image scales of interest are readily selected from multi-scale image processing paradigm. SVM is used to encode visual object information of significant image scale only; hence its use is efficient. Experiment with MPEG-4 video object encoding and classification shows that the performance of the proposed model is comparable with other models, however with significantly reduced computational requirements.

Bending sensor with tilted fiber Bragg grating interacting with multimode fiber

A new type fiber bending sensor based on a tilted fiber Bragg grating (TFBG) interacting with a multimode fiber (MMF) is presented. The sensing head is formed by insertion a small section of MMF between single-mode fiber (SMF) and the TFBG. The reflective power in the cladding modes is decreased with the increase of curvature.
“I Can Relate”: Survivor Leadership Supporting Women Transitioning Out of the Sex Trade

In this article, the authors examine the value of survivor leaders in organizations helping women transition out of the sex trade and how organizations can best utilize survivor leaders. They interviewed 10 women who have been out of the sex trade from between 3 and 20 years. They found survivor leaders (a) created relatability for participants exiting out of the sex trade, (b) modeled a hopeful future, and (c) mitigated power issues. The authors uncovered three ways organizations can engage survivor leaders: (a) on boards, (b) in paid staff positions, and (c) as volunteers. They discuss the ethical and financial issues associated with organizations using unpaid and paid survivor leaders. Furthermore, the authors recommend practical ways organizations can improve by engaging survivor leaders in peer education, policy setting, and management. They also encourage organizations to view survivors as experts. The authors’ findings move adult education beyond a focus on peer education to considering peer leadership.
