Do private inspection programs affect trade facilitation ?

Private inspection of international shipments has been used over the last half-century for a variety of purposes. These include prevention of capital flight and improvement of import duty collection, among others. The existing literature has failed to find much impact of these inspection programs on collected tariff revenue or corruption at the border. This paper explores the"facilitation"effect of private inspection programs on trade. The results indicate that private inspection has a positive and significant trade-facilitation effect. These programs raise import volumes for countries using them by approximately 2 to 10 percent. The findings here also suggest that the benefit of private inspection of imports may be associated with reforms and best practices applied by private inspection firms. Private firms'inspection of cargo may promote faster clearance times and process reliability, rather than improved tax collection.E-Business,Transport Economics Policy&Planning,Trade Law,Free Trade,Economic Theory&Research

A Community-Based Sensor Network for Monitoring the Air Quality in Urban Romania

Air quality, especially particulate matter pollution levels in urban areas, is an essential academic and social topic due to its association with health issues and climate change. In Romania, increasing awareness of urban communities and the availability of low-cost sensors has led to the development of an independent monitoring network currently distributed in over 194 cities and towns. The uRADMonitor((R)) network consists of 630 sensors measuring PM10 and PM2.5 concentration levels. The spatial distribution of the sensors complements the national air quality network with sensors in residential areas, intense traffic zones, and industrial areas. The data are available through a user-friendly web-based platform from uRADMonitor((R)). Based on data collected in 2021, we present an analysis of PM10 pollution levels in Romania's five most populated urban areas by employing five annual statistical indicators recommended by the European Environmental Agency. For the case of Timis,oara, we also compare the data measured by independent sensors with those from the national monitoring network. The results highlight the usefulness of our community-based network as it complements the national one

The roles of dispositional coping style and social support in helping people with respiratory disease cope with a breathlessness crisis

© 2019 John Wiley & Sons Ltd Aim: To explore the role of coping moderators in self-management of breathlessness crises by people with advanced respiratory disease. Design: A secondary analysis of semi-structured interview data. Methods: Interviews with patients who had advanced respiratory disease, chronic breathlessness and at least one experience where they considered presenting to Emergency but self-managed instead (a “near miss”). Participants were recruited from New South Wales, Queensland, Victoria, South Australia or Tasmania. Eligible caregivers were those who contributed to Emergency-related decision-making. Interviews were coded inductively and then deductively against the coping moderators social support and dispositional coping style, defined by the Transactional Model of Stress and Coping. Results: Interviews were conducted between October 2015 - April 2016 with 20 patients and three caregivers. Social networks offered emotional and practical support but also had potential for conflict with patients' ‘hardy’ coping style. Patient hardiness (characterized by a sense of ‘commitment’ and ‘challenge’) promoted a proactive approach to self-management but made some patients less willing to accept support. Information-seeking tendencies varied between patients and were sometimes shared with caregivers. An optimistic coping style appeared to be less equivocally beneficial. Conclusion: This study shows that social support and coping style may influence how people self-manage through their breathlessness crises and identified ways coping moderators can facilitate or hinder effective self-management. Impact: This study confers insights into how social-support and coping style can be supported and optimized to facilitate breathlessness self-management. Acknowledging coping moderator interactions is beneficial for developing resources and strategies that recognise patient mastery

A Pre-Landing Assessment of Regolith Properties at the InSight Landing Site

This article discusses relevant physical properties of the regolith at the Mars InSight landing site as understood prior to landing of the spacecraft. InSight will land in the northern lowland plains of Mars, close to the equator, where the regolith is estimated to be ≥3--5 m thick. These investigations of physical properties have relied on data collected from Mars orbital measurements, previously collected lander and rover data, results of studies of data and samples from Apollo lunar missions, laboratory measurements on regolith simulants, and theoretical studies. The investigations include changes in properties with depth and temperature. Mechanical properties investigated include density, grain-size distribution, cohesion, and angle of internal friction. Thermophysical properties include thermal inertia, surface emissivity and albedo, thermal conductivity and diffusivity, and specific heat. Regolith elastic properties not only include parameters that control seismic wave velocities in the immediate vicinity of the Insight lander but also coupling of the lander and other potential noise sources to the InSight broadband seismometer. The related properties include Poisson’s ratio, P- and S-wave velocities, Young’s modulus, and seismic attenuation. Finally, mass diffusivity was investigated to estimate gas movements in the regolith driven by atmospheric pressure changes. Physical properties presented here are all to some degree speculative. However, they form a basis for interpretation of the early data to be returned from the InSight mission.Additional co-authors: Nick Teanby and Sharon Keda

The effect of pre-incubation of Allium cepa L. roots in the ATH-rich extract on Pb uptake and localization

The positive influence of anthocyanin (ATH) on toxic metal-treated plant material is well documented; however, it is still not explained if it is caused by changes in element absorption and distribution. Therefore, detailed analysis of the effect of the ATH-rich extract from red cabbage leaves on Pb uptake and localization at morphological, anatomical and ultrastructural level was the goal of this study. Two-day-old adventitious roots of Allium cepa L. (cv. Polanowska) were treated for 2 h with the aqueous solution of Pb(NO3)2 at the concentration of 100 μM with or without preliminary incubation in the anthocyanin-rich extract from Brassica oleracea L. var. capitata rubra leaves (250 μM, 3 h). The red cabbage extract did not change the total Pb uptake but it enhanced the translocation of accumulated metal from roots to shoots. Within the pretreated roots, more Pb was deposited in their basal part and definitely smaller amount of the metal was bound in the apoplast of the outer layers of cortex cells. The ultrastructural analysis (transmission electron microscopy and X-ray microanalysis) revealed that the ATH-rich extract lowered the number of Pb deposits in intracellular spaces, cell wall and cytoplasm of root meristematic cells as well as in such organelles important to cell metabolism as mitochondria, plastids and nucleus. The Pb deposits were preferably localised in those vacuoles where ATH also occurred. This sequestration of Pb in vacuoles is probably responsible for reduction of metal cytotoxicity and consequently could lead to better plant growth.This work was supported by the grant of the University of Lodz, no. 505/04038

Heterotrophic and mixotrophic microalgae cultivation

This chapter discusses the cultivation of microalgae under heterotrophic and mixotrophic conditions in terms of market pull (societal challenge and demand readiness level) and technology push (technology readiness level). Heterotrophic cultivation, possible on microalgae strains presenting the needed metabolic pathways, benefits from the already developed microbial biosynthesis technological subsystems—bioreactors/fermenters, downstream processing equipment, (bio)sensors, and automated control. Large-scale production of high value-added ingredients (e.g., phycobilins or carotenoids like astaxanthin) is technologically possible and responds to an increasing demand for bioactives. Mixotrophic cultivation has the advantages of reduced operation cost and higher yield. Such a cultivation technique, which enables transformation of waste with solar power into algae mass, is therefore a key enabling technology for a circular bioeconomy. Mixotrophically grown microalgae sequestrate CO2 while simultaneously synthesizing value-added products. In summary, this chapter reviews the present evolution of heterotrophic and mixotrophic cultivation technologies of microalgae and identifies several research and innovation needs for better harnessing the microalgae's potential

Flexible, graphene-based active implant for spinal cord stimulation In rodents

The most important symptoms of spinal cord injuries (SCIs) are partial or complete loss of sensory and/or motor functions caused by the disruption of the neural pathway between the brain and the extremities of the body. Recent studies have shown that epidural spinal cord stimulation (ESCS) can promote locomotor recovery in patients affected by SCIs, thus becoming one of the most promising means of treatment for the lesion. Devices currently available on the market, consist of active components, enclosed in a hard case and connected via leads to the electrodes that form the interface between the stimulator and the biological tissue. The presence of leads along the spine, may be an important cause of failure for the device. Moreover, the overall stiffness of the stimulator does not resemble best the anatomical structure of the human body. Flexibility and optical monitoring of the biological tissue during implantation and stimulation are very important aspects and both can be improved with a proper choice of materials. The goal of this work is to develop a compact, active, transparent and flexible spinal cord stimulator that could be implanted at the site of stimulation. To provide high flexibility, soft encapsulation, using polydimethylsiloxane (PDMS) has been used. To ensure transparency but also mechanical stability of the electrodes and tracks, graphene has been chosen as a replacement for the conventional metals. Integrating active components, in the form of application specific integrated circuits (ASICs), on a graphenebased substrate, constitutes the biggest challenge. To this end, flip chip bonding techniques using a metal layer as an interface between graphene and the chip’s stud-bumped pads, are being investigated. Preliminary measurements after bonding have shown resistance values in the range of kΩ, thus taking the project one step closer to achieving the desired goal
