AbstractDirect evidence of the control of yield, thermal stability and photoluminescence property of the polyaniline (PANI) nanofibers have been reported by systematically varying the reaction time in the range of 2–6 hours (h) in the synthesis process. Both FTIR and UV–visible spectra revealed the formation of PANI fibers for all synthesis batches. The mass of the obtained PANI was increased with the increase of reaction time from 2 to 6 h. FESEM data confirmed the formation of PANI in nanofibers form for all the synthesis batches. TGA data showed that the highest thermal stability of PANI nanofibers could be obtained for the 4 h reaction time. PL data indeed showed the variation of luminescence intensity of PANI with the reaction time which indicate the formation of different quality fibers in terms of theirπconjugation. Thus the three main results can be summarized: one is the increase of PANI fibers yield and another two are the thermal stability and luminescence property modification which shows that such properties of PANI can be controlled by varying the reaction time of the synthesis process.

AbstractBubble size distribution (BSD) is important for gas-liquid jet loop reactor (JLR)’s mass transfer performance of inter-phases. A self-designed reversed JLR was investigated with air-water system on the BSD. The CCD camera of particle imaging velocimetry (PIV) system and image processing technique were used to obtain the reliable photo. The influences of four parameters, gas phase flow rate, liquid phase flow rate, draft tube diameter and ejector mounting position, on the BSD were studied in detail. The results showed that the local BSD is accordance with log-normal distribution under the experimental conditions and the average diameter and BSD range increase with the increase of the gas phase flow rate, and decrease with the increase of the liquid phase flow rate, the downward movement of the nozzle installation position and the increase of the diameter of the draft tube.
Antibacterial Activity of Phenyllactic acid Against Staphylococcus Epidermidis and Its Microbial Production: Modelling and Optimization-Based Analysis

Published: October 2019

Abstract
Phenyllactic acid (PLA), an organic acid with extensive antimicrobial activity, is considered as a promising natural preservative to replace chemical preservatives. In order to study the inhibitory pattern of PLA, this paper established a novel mathematical model for the growth of Staphylococcus epidermidis under PLA inhibition. The simulated results showed that the relationship between the antimicrobial activity of PLA against S. epidermidis and its concentration was suitable to be represented by an exponential function. Based on the proposed model, the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of PLA against S. epidermidis were evaluated. The computed results were found to match experimental data. The MBC value was found to be independent of the initial biomass of S. epidermidis from both the simulated results and experimental data, revealing that PLA was not consumed while killing the bacteria. Another kinetic model was established to describe the production of PLA by the engineered Escherichia coli. This model was then used to calculate the minimum biomass of E. coli to produce the MBC of PLA. The proposed models help to understand the inhibitory pattern of PLA, serving as a theoretical guide for the selection an appropriate strain to improve the product shelf-life.

Authors: Perone Nicola 
Published: October 2019

Abstract
A high-fidelity simulator is described here, specifically designed for vacuum extraction and forceps delivery training. The main purpose behind its development is to remedy the current limited opportunity for training in operative vaginal delivery (OVD), making it easier for young obstetricians to become proficient in this important area of obstetrics. Its introduction into teaching hospitals and academic departments may also help older obstetricians maintain their own competence during periods of inactivity, ensuring patient safety.
A broad overview on innovative functionalized paper solutions
Authors: Aguado Roberto , Murtinho Dina , Valente Artur J. M. 
Published: October 2019

Abstract
Functionalized paper solutions have attracted the attention of many research groups in the 21st century, given the low cost, availability, flexibility and biodegradability of paper. Despite this material has been manufactured for more than two thousand years, its traditional uses hardly go beyond writing, printing, cleaning and packaging. This overview covers fascinating advances in the functionalization of paper that have taken place this century. This century, test strips for glucose and pH have evolved towards microfluidic paper analytical devices that allow for accurate quantitative determinations. In another context, paper electronics started with the first paper-based transistors and followed with more sophisticated electronic devices. Also, cheap paper-based membranes and adsorbents have been proposed for water treatment, and researchers have found innovative ways to confer antimicrobial and anti-counterfeiting properties to paper. Furthermore, numberless ways to functionalize paper are reported here. Fibers can be modified by chemical reactions, nanofibrillation or supramolecular interactions with certain reagents. The surface can be coated by diverse methods, including size press coating, sputtering, e-beam evaporation and the sol-gel process. Special inks can be printed onto paper to make hydrophobic, conductive or luminescent patterns. Brief opinions about future outlooks are given at the end.
“Listen, Marxist!”: On the Forgotten Past of Self-Management and the Contemporary Orgasms of History
Authors: Vodovnik Žiga 
Published: October 2019

Abstract
In this article, we argue that self-management should not be understood only as an economic project, but rather as a political form based on the transformation of the core principles of modern capitalist societies. We start from the supposition that self-management does not imply an economic, but primarily a political recomposition of society, which is why it is necessary to draw attention to the economic reductionism in the discussions on self-management. The purpose of this article is three-fold: first, we recover the original meaning of self-management, its forgotten, anarchist (pre)history, and elaborate on the anarchist theory of organisation that has dynamised the idea/practice of self-management throughout history. Second, we analyse Yugoslav self-management through the categories and concepts of Praxis philosophy, which leads us to the conclusion that the Yugoslav model of self-management was above all a non-political form that remained in the framework of liberal democratic theory. Finally, we explore the global mass assembly movement Occupy, building on the recent academic attention devoted to the notion of non-state spaces. We analyse the encampments and occupied squares as self-managed exilic spaces in which protesters (in)voluntarily escaped from both state regulation and capitalist accumulation.
Addressing the Teacher Preparation Gap for ELs
Authors: Bundy Erica 
Published: October 2019

English Learners as a student population are increasing in US Schools and migrating to new areas. A review of research shows that teachers are underprepared to meet the unique linguistic and cultural needs and leverage the strengths of this student population. This memo explores the problem space, reviews relevant research and current practices in pre-service education and in-service professional development. Guiding the research and current practices are two essential questions: Is this preparation method effective in changing teacher practice and improving student outcomes? Is this method permeating the educational sphere enough to produce change? The memo details a three prong solution to addressing the teacher preparation gap and concludes by discussing limitations of the memo and approach.
Impacts of alien plant invasions on water resources and yields from the Western Cape Water Supply System (WCWSS)
Authors: Le Maitre David , Görgens André , Howard Gerald , Walker Nick 
Published: October 2019

A key motivation for managing invasive alien plant (IAP) species is their impacts on streamflows, which, for the wetter half of South Africa, are about 970 m3∙ha−1∙a−1 or 1 444 mill. m3∙a−1 (2.9% of naturalised mean annual runoff), comparable to forest plantations. However, the implications of these reductions for the reliability of yields from large water supply systems are less well known. The impacts on yields from the WCWSS were modelled under three invasion scenarios: ‘Baseline’ invasions; increased invasions by 2045 under ‘No management’; and under ‘Effective control’ (i.e. minimal invasions). Monthly streamflow reductions (SFRs) by invasions were simulated using the Pitman rainfall−runoff catchment model, with taxon-specific mean annual and low-flow SFR factors for dryland (upland) invasions and crop factors for riparian invasions. These streamflow reduction sequences were input into the WCWSS yield model and the model was run in stochastic mode for the three scenarios. The 98% assured total system yields were predicted to be ±580 million m3∙a−1 under ‘Effective control’, compared with ±542 million m3∙a−1 under ‘Baseline’ invasions and ±450 mill. m3∙a−1 in 45 years’ time with ‘No management’. The ‘Baseline’ invasions already reduce the yield by 38 mill. m3∙a−1 (two thirds of the capacity of the Wemmershoek Dam) and, in 45 years’ time with no clearing, the reductions would increase to 130 mill. m3∙a−1 (capacity of the Berg River Dam). Therefore IAP-related SFRs can have significant impacts on the yields of large, complex water supply systems. A key reason for this substantial impact on yields is that all the catchments in the WCWSS are invaded, and the invasions are increasing. Invasions also will cost more to clear in the future. So, the best option for all the water-users in the WCWSS is a combined effort to clear the catchments and protect their least expensive source of water.
Evaluation of acidogenic sludge from anaerobic reactors running at low solids retention times to reduce sludge generation and enhance biogas production

Published: October 2019

ABSTRACT

Sludges generated in the biological processing of sewage are complex mixtures, the constituents of which pose risks to public health and the environment. Anaerobic digestion is considered the most sustainable option for treating sludge because it offers the possibility of generating biogas. The aim of this study was to compare the quantities, properties, biodegradabilities and biochemical methane potentials (BMP) of primary sludge (PS) generated by a primary decanter with acidogenic sludges produced by upflow anaerobic (UA) reactors operating at solids retention times (SRTs) of 2, 4, 6 and 8 days (Samples S2, S4, S6 and S8, respectively). Sludges from both pre-treatments were submitted to alkaline solubilization in order to determine the efficiency of the process in disrupting extracellular complexes. Based on the levels of total solids (TS) present, the primary decanter was found to generate higher quantities of excess sludge (yield of 3.1 gTS∙d-1) than UA reactors operating at low SRTs (yields in the range 1.69 to 0.64 gTS∙d-1). The concentrations of dissolved materials in PS and Samples S2 and S8 were considerably higher after alkaline solubilization, with respective increases of 8, 14 and 28-fold in dissolved organic carbon, 12, 20 and 40-fold in chemical oxygen demand, 25, 31 and 59-fold in proteins, and 17, 21 and 63-fold in carbohydrates. In addition, the BMP value for S8 was some 13% higher than that recorded for PS while the kinetic constant for gas production by S8 was 1.8-fold greater than that of PS. It is concluded that a pre-treatment combining anaerobic digestion at low SRT and alkaline solubilisation would lead to improved performance in subsequent stages of anaerobic digestion and, consequently, increased efficiency in biogas production.

Abstract
The eastern North American margin community seismic experiment (ENAM‐CSE) was conceived to target the ENAM Geodynamic Processes at Rifting and Subducting Margins (GeoPRISMS) primary site with a suite of both active‐ and passive‐source seismic data that would shed light on the processes associated with rift initiation and evolution. To fully understand the ENAM, it was necessary to acquire a seismic dataset that was both amphibious, spanning the passive margin from the continental interior onto the oceanic portion of the North American plate, and multiresolution, enabling imaging of the sediments, crust, and mantle lithosphere. The ENAM‐CSE datasets were collected on‐ and offshore of North Carolina and Virginia over a series of cruises and land‐based deployments between April 2014 and June 2015. The passive‐source component of the ENAM‐CSE included 30 broadband ocean‐bottom seismometers (OBSs) and 3 onshore broadband instruments. The broadband stations were deployed contemporaneously with those of the easternmost EarthScope Transportable Array creating a trans‐margin amphibious seismic dataset. The active‐source portion of the ENAM‐CSE included several components: (1) two onshore wide‐angle seismic profiles where explosive shots were recorded on closely spaced geophones; (2) four major offshore wide‐angle seismic profiles acquired with an airgun source and short‐period OBSs (SPOBSs), two of which were extended onland by deployments of short‐period seismometers; (3) marine multichannel seismic (MCS) data acquired along the four lines of SPOBSs and a series of other profiles along and across the margin. During the cruises, magnetic, gravity, and bathymetric data were also collected along all MCS profiles. All of the ENAM‐CSE products were made publicly available shortly after acquisition, ensuring unfettered community access to this unique dataset.
Military Rhetoric in the Description of Women’s Behavior on the Basis of Cicero’s and Livy’s Selected Texts
Authors: Dziuba Agnieszka 
Published: October 2019

The Polish version of the article was published in Roczniki Humanistyczne vol. 60, issue 3 (2012).
The article analyzes the original and rare Roman military phraseology found in surviving works of literature, which is part of the convention of invectives against women. As testified by the surviving fragments of the Law of the Twelve Tables, the Roman civilization divided the sphere of men’s activities (politics and war) from the sphere of women’s activities (home and family) quite early. Literature imbued with didacticism supported this division by creating archetypal figures of ideal representatives of both genders. In the course of development it worked out a stereotyped phraseology that served the purpose of describing virtutes feminae and, separately, men’s virtues, corresponding to the spheres ascribed to them. Any breach of the order established by tradition (mores maiorum) and law encountered severe reprimands, which nevertheless remained within the rhetorical convention of vituperatio. The two texts by outstanding rhetors that are analyzed here—Cato the Elder’s speech against the repeal of the Oppian law (AUC 34, 2-4) by Livy and Marcus Tullius Cicero’s speech Pro Caelio—supply examples of the use of military phraseology, usually used to describe typically male activities, in descriptions of women’s behavior. In the case of Marcus Porcius Cato’s speech, vocabulary belonging to the field of military science (agmen, expugnare, obsidere, coniuratio, seditio) serves the purpose of inducing fear in the men listening to him. In this way, by using the threat of power being seized in the republic by women, the consul motivated patres familias to act and not to yield to women. In the case of Cicero’s speech, military rhetoric was used to ridicule and embarrass Clodia Metelli as a credible witness for the prosecution in the trial of Marcus Caelius Rufus. Aggressive and at times obscene humor was supposed to divert the listeners’ attention from the defense’s lack of arguments concerning the substance of the trial.
The original military phraseology used by both authors serves definite practical aims. What is more, its artistic dimension is decidedly pushed into the background. Cicero’s and Livy’s surprising idea allows us, on the one hand, to appreciate their ingeniousness in the field of rhetoric and their conscious rejection of conventions; on the other, it helps the contemporary reader of ancient texts realize the fact that men of the period of the Republic found it difficult to keep women within the limits imposed by tradition. They were forced to resort to sophisticated verbal argumentation in order to convince the judges and politicians (in both these groups patres familias prevailed) about the real threat posed by the ones in their charge.
Elements of the Mime in Horace’s Epode “Quid tibi vis, mulier”
Authors: Kopek Wojciech 
Published: October 2019

The Polish version of the article was published in Roczniki Humanistyczne vol. 61, issue 3 (2013).
The aim of this article is to discover the literary context for Horace’s Epode 12 by juxtaposing it with Herondas’ mimes, particularly Mime 5, titled The Jealous Woman. The description of the relationship between these works is based on the ancient theory of rhetoric and on elements of Horace’s Ars poetica. It has been established that Epode 12 has numerous features of the literary mime: it is an apparent dialogue (sermocinatio, παρῳδή) recited by a single performer (mime), most probably in the scenery of an ancient feast. A participant in the feast becomes an actor, who first performs the role of a male lover (iuvenis) and then the role of a superannuated female lover (mulier). These character types are typical of both Old and New Comedy styles, but the whole dramatic setting seems to bear the greatest resemblance to Mime 5, in which the same literary protagonists are found in a scene analogous to a lovers’ quarrel. On the one hand, specific rhetorical figures (imitatio / μίμησις) indicate that the literary original was used in a creative manner. On the other, Mime 5 can also be used in the interpretation of Epode 12. This interpretation can be built on the processes of liberation and subjugation as part of the lovers’ relationship (actual subjugation in Mime 5 and metaphorical—financial—in Epode 12, where the iuvenis is the mulier’s “kept man”).

Background: Exercise training affects the adipose tissue, which may lead to the secretion of adipokines. This study aimed to evaluate the effect of endurance exercise training on vaspin, lipid profiles, and some anthropometric indices among young people. Methods: The participants included 26 young men selected and categorized into the intervention and control groups randomly. The intervention group underwent the endurance activity (aerobic), while the control group had no exercises during the study. Anthropometric indices and dietary intakes were determined by standard and 48-hr recall methods, respectively. Before and after implementation of the exercise training, the participants' fasting blood samples were collected. Lipid profile (including cholesterol, triglyceride, LDL, and HDL) and vaspin levels were determined. Results: A significant difference was observed in body fat percentage of the intervention group after exercise training (P = 0.009). However, no significant differences were observed based on the means of anthropometric indices, lipid profile, and daily energy intake between two groups. With regard to the vaspin levels, a significant difference was observed between the participants' scores before (P = 0.001) and after (P = 0.04) the exercise training in intervention compared to the control group.
Conclusion: Endurance exercise program can lead to appropriate changes in some anthropometric indices, lipid profile, and vaspin adipokine in young people. So, exercise training can affect health promotion of people.
