One of the limitations in studying dusty plasmas is that many of the important properties of the dust (like the charge) are directly coupled to the surrounding plasma conditions rather than being determined independently. The application of high-intensity ultraviolet (UV) sources to generate discharging photoelectric currents may provide an avenue for developing methods of controlling dust charge. Careful selection of the parameters of the UV source and dust material may even allow for this to be accomplished with minimal perturbation of the background plasma. The Auburn Magnetized Plasma Research Laboratory (MPRL) has developed a ‘proof-of-concept’ experiment for this controlled photo-discharging of dust; a high-intensity, near-UV source was used to produce large changes in the equilibrium positions of lanthanum hexaboride ( $\textrm {LaB}_6$ ) particles suspended in an argon DC glow discharge with negligible changes in the potential, density and temperature profiles of the background plasma. The shifts in equilibrium position of the dust are consistent with a reduction in dust charge. Video analysis is used to quantify the changes in position, velocity and acceleration of a test particle under the influence of the UV and Langmuir probes are used to measure the effects on the plasma.

PurposeThe maintenance of process improvement programs within organizations is not an easy task. Some processes do not maintain the results achieved with the improvement project and again present low performance shortly after completion of the project. This paper aims to identify the socio-technical causes responsible for the loss of process performance after applying improvement projects, in order to support the mitigation of the problem.Design/methodology/approachA systematic review of the literature was carried out, which allowed the selection of 28 articles. The empirical stage used the benchmarking technique, along a large Brazilian mining company with an international standard of production and quality. This organization has been using improvement projects for more than ten years.FindingsThe research complements the literature regarding the prioritization of the 26 identified failures and the identification of seven new failure factors and two resources. Findings in this study can be an inspiration for other organizations, considering the similarity of methodological aspects of improvement projects since internationally standardized methodologies such as Six Sigma, Lean, Kaizen and 5S are used.Originality/valueThe research presented a proposal of guidelines that corroborate to the mitigation of loss of process performance after improvement project.

Ecological, economic and societal challenges require decision-making and planning processes aiming at sustainability in water management. Such processes are increasingly informed and supported by sustainability assessment schemes. The focus of this article is on water infrastructure. A selection of national (German) and international assessment schemes is presented and compared. Both interdisciplinary schemes, applicable to a wide range of infrastructure measures, as well as schemes specialized in water infrastructure are considered. In addition to methodological aspects and dissemination, thematic priorities are analyzed and compared. Apart from methodological similarity, specialized schemes tend to be still in the development stage. In contrast, the interdisciplinary schemes have already been used commercially and have been applied in a considerable number of projects. The schemes considered differ significantly in the number of criteria. The interdisciplinary schemes tend to focus more on the ecological dimension while considering a small number of economic criteria. The assessment results depend on various subjective factors and the schemes do not produce true or false results in absolute terms. However, their application can make these factors visible and help identify the most stable solution with regard to different sustainability perspectives.

AbstractA potential method to produce isolated attosecond pulses (IAPs) by using low-intensity chirped-UV combined field has been investigated. The results can be separated into three parts. First, by properly introducing the mid-chirp or down-chirp of the low-intensity laser field, the harmonic cutoff can be extended and achieve the referenced value, which is produced from the high-intensity referenced field. Moreover, the spectral continuum is contributed by a single harmonic emission peak, which is beneficial to produce IAPs. However, the harmonic yield is very low due to the lower driven laser intensity. Second, by properly adding a UV pulse, the harmonic yield can be enhanced and achieve the referenced value due to the UV resonance ionisation. The intensity of the combined field is lower than that of the referenced field, which reduces the experimental requirements for producing high-intensity spectral continuum. Third, with the introduction of the positive or negative inhomogeneous effect of the mid-chirped combined field or down-chirped combined field, respectively, the similar harmonic cutoff and harmonic yield can also be obtained but with a much lower driven laser intensity. Finally, by superposing the harmonics on the spectral continuum, the IAPs with the durations of sub-38 as can be obtained.

In recent years, the consumption of polyphenols has been increasing, largely due to its beneficial effects on health. They are present in a wide variety of foods, but their extraction and characterization are complicated since they are mostly in complex matrices. For this reason, the use of selective, sensitive, and versatile analytical techniques such as liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) is necessary. In this review, the most relevant studies of the last years regarding the analysis of polyphenols in different matrices by comprehensive LC–MS/MS are discussed. Relevant steps such as extraction, sample purification, and chromatographic analysis methods are emphasized. In particular, the following methodological aspects are discussed: (a) the proper selection of the extraction technique, (b) the extraction and elution solvents, (c) the purification step, (d) the selection of both stationary and mobile phases for the chromatographic separation of compounds, and (e) the different conditions for mass spectrometry. Overall, this review presents the data from the most recent studies, in a comprehensive way, thus providing and simplifying the information of the great variety of works that exist in the literature on this wide topic.

Purpose The purpose of this paper is to provide an analysis of the studies about workaround behavior in the Information Systems (IS) area, addressing its positive and negative aspects and raising the key related issues. Design/methodology/approach A systematic literature review was conducted to verify how workaround behavior has been approached in IS studies. A qualitative method was adopted and implemented in two stages: selection of articles from the time period 2007-2017 in the databases Web of Science, ScienceDirect and Scopus and analysis of the selected articles. Findings The results showed that many studies have been concerned with identifying the principal reasons for the manifestation of workaround behavior and the measures taken to reduce its impacts. Many studies from international journals examined the implementation of an ERP along with the workaround behavior. The need to expand the national studies on workaround behavior is emphasized, because the majority of the identified studies are international. Research limitations/implications The key limitation is related to the period of analysis, because only articles published since 2007 were selected. Practical implications This paper contributes to both theory and practice, bringing relevant concepts about workaround behavior, and corroborating the importance of the studies on workaround in the IS area. The literature review of the 20 articles analyzed reveals the main features in each article, such as theoretical and methodological aspects that support the research. Based on this analysis, a conceptual map was developed presenting the most relevant points about workaround behavior, where the causes, the negative and positive consequences, the types of solutions and the organizational and individual impacts are presented. Originality/value Research into workaround behavior has increased in recent years, however very few studies have been conducted in Brazil. To the best of the authors' knowledge, no articles regarding Brazil and this subject were published between 2007 and 2017. Thus, this paper seeks to redress this imbalance.
