Long‐term Changes in Soil and Stream Chemistry across an Acid Deposition Gradient in the Northeastern United States
Authors: Siemion Jason , McHale Michael R. , Lawrence Gregory B. , Burns Douglas A. , Antidormi Michael 
Published: May 2018

Declines in acidic deposition across Europe and North America have led to decreases in surface water acidity and signs of chemical recovery of soils from acidification. To better understand the link between recovery of soils and surface waters, chemical trends in precipitation, soils, and streamwater were investigated in three watersheds representing a depositional gradient from high to low across the northeastern United States. Significant declines in concentrations of H+ (ranging from −1.2 to −2.74 microequivalents [μeq] L−1 yr−1), NO3− (ranging from −0.6 to −0.84 μeq L−1 yr−1), and SO42− (ranging from −0.95 to −2.13 μeq L−1 yr−1) were detected in precipitation in the three watersheds during the period 1999 to 2013. Soil chemistry in the A horizon of the watershed with the greatest decrease in deposition showed significant decreases in exchangeable Al and increases in exchangeable bases. Soil chemistry did not significantly improve during the study in the other watersheds, and base saturation in the Oa and upper B horizons significantly declined in the watershed with the smallest decrease in deposition. Streamwater SO42− concentrations significantly declined in all three streams (ranging from −2.01 to −2.87 μeq L−1 yr−1) and acid neutralizing capacity increased (ranging from 1.38 to 1.60 μeq L−1 yr−1) in the two streams with the greatest decreases in deposition. Recovery of soils has likely been limited by decades of acid deposition that have leached base cations from soils with base‐poor parent material.Core Ideas
Reductions in acidic atmospheric deposition have accelerated in recent years.
Some streams, but not all, have shown a degree of recovery.
Soils have not shown a clear indication of recovery despite reductions in deposition.
Soil chemical recovery that has been evident has been limited to the Oa and A horizons.
Use of bacterial spores in monitoring water quality and treatment
Authors: Stelma Gerard N. 
Published: April 2018

Abstract
Because Clostridium perfringens spores are both specific to sewage contamination and environmentally stable, they are considered as possible conservative indicators of human fecal contamination and possible surrogates for environmentally stable pathogens. This review discusses the reasons and summarizes methods for monitoring spores in water. Cultural methods are still preferred over qPCR for routine water quality monitoring because of their low costs. Membrane filter (MF) methods are preferred over the more laborious and less accurate most probable number methods. The most commonly used MF media are TSC medium and mCP medium. TSC normally allows higher recoveries than mCP. TSC produces fewer false-positive results than mCP; however, it does produce more false-negatives. Two newer methods have substantial potential, CP Chromo Select agar, which allows better recoveries and greater specificity than mCP, and the Fung double tube method, which creates anaerobic conditions and allows enumeration of colonies in tubes in 5–6 hours. Aerobic spores are not associated with fecal contamination but they can be surrogates for environmentally stable pathogens in monitoring water for treatment efficacy; Bacillus cereus spores are normally measured on nutrient agar by the MF method.
Effects of weather conditions on drinking water distribution pipe failures in the Netherlands

Published: April 2018

Abstract
The influence of the weather parameters of temperature, wind and drought on pipe failure of drinking water distribution pipes was studied for the Netherlands. Several data sources were used relating weather effects to pipe failure: pipe failure data, regional weather data from different weather stations in the Netherlands, soil settlement data obtained from satellites and (modelled) pressure data. For asbestos-cement (AC) and cast iron (CI) pipes, temperature was an important factor. CI pipes showed increased pipe failures at low temperatures, which confirms results from previous studies, whereas AC pipes showed increased pipe failures at high temperatures. Pipe failure rates were higher for pipes that on average received higher internal pressures. This study also showed that wind resulted in additional pipe failures caused by uprooting of trees during a severe storm. With respect to drought, in some regions in the Netherlands, increased pipe failures during periods of drought were found. A small influence of soil settlement on pipe failure was found using remote-sensing techniques for a small area (5 × 10 km) in the Netherlands.

Published: May 2018

Abstract
A SULPHUSTM biotrickling filter (BTF) and an ACTUSTM polishing activated carbon filter (ACF) were used at a wastewater treatment plant to treat 2,432 m3·h−1 of air extracted from sewage sludge processes. The project is part of Thames Water's strategy to reduce customer odour impact and, in this case, is designed to achieve a maximum discharge concentration of 1,000 ouE·m−3. The odour and hydrogen sulphide concentration in the input air was more influenced by the operation of the sludge holding tank mixers than by ambient temperature. Phosphorus was found to be limiting the performance of the BTF during peak conditions, hence requiring additional nutrient supply. Olfactometry and pollutant measurements demonstrated that during the high rate of change of intermittent odour concentrations the ACF was required to reach compliant stack values. The two stage unit outperformed design criteria, with 139 ouE·m−3 measured after 11 months of operation. At peak conditions and even at very low temperatures, the nutrient addition considerably increased the performance of the BTF, extending the time before activated carbon replacement over the one year design time. During baseline operation, the BTF achieved values between 266–1,647 ouE·m−3 even during a 6 day irrigation failure of the biofilm.
Soy Isoflavones and their Effects on Xenobiotic Metabolism
Authors: Zhou Tianjiao , Meng Chengzhen , He Pingli 
Published: April 2018

Background:Soy isoflavones, such as genistein and daidzein, are bioflavonoids found in soy products that are able to interact with various hormones such as estrogen. Epidemiological studies reveal a proper level of isoflavones in diet can prevent many diseases like cancers or diabetes. Therefore, it is important to study the biotransformation and xenobiotic metabolism of soy isoflavones.Methods:A systematic review of published studies was carried out to investigate the characterization of isoflavones and their metabolites, sample pretreatment and quantitative analysis of isoflavones, and the influence of soy isoflavones on drug and xenobiotic metabolism.Results:Aglycones with weak estrogen-like activities are the biologically active forms of the soy isoflavones in mammals. The most recent advances including extraction, purification and detection of isoflavones in soybean and soy products are discussed. The effects of soy isoflavones on drug and xenobiotic metabolism involve in regulation of phase I cytochrome P450 (CYPs) enzyme and phase I detoxifying enzymes expression and activity. At the molecular level, soy isoflavones have proved capable of estrogenic/antiestrogenic with tissue-selective, anti-cancer, antiobesity, anti-oxidation, and tyrosine kinase inhibition activities.Conclusion:This review summarized different aspects of soy isoflavones and their molecular mechanisms of pharmacological action on xenobiotic, which demonstrated that soy isoflavones can decrease the incidence of many diseases and benefit for human health. However, since the lack of clinical research for evaluation of the proper dosage of intake of soy isoflavones in diet or adjunctive therapy, there is a need for further studies on the selection of doses, biomedical applications and adverse effects of isoflavones for human health.

Authors: Vatutin Nikolay Т. , Taradin Gennadiy G. , Smyrnova Ganna S. , Kostogryz Valery B. Kostogryz B. , Kolesnikov Vadim S. , Dmitriev Andrey V. 
Published: April 2018

Background:
Uterine fibroid embolization (UFE) is as an effective alternative to
hysterectomy and myomectomy. However, UFE is associated with a wide spectrum of complications
including in rare instances thromboembolic events and even pulmonary embolism (PE).

Case Presentation:
A case of a 36-year-old woman suffering from a symptomatic uterine fibroid is
described as follows. The patient underwent UFE and overnight she suddenly collapsed with signs of
massive PE. In consequence of cardiopulmonary resuscitation and urgent systemic thrombolytic
therapy, cardiac activity was restored successfully.

Discussion & Conclusion:
This constitutes another report of PE developed following UFE. In the
case described here PE occurred 26 hours after the procedure was performed. Before UFE all patients
should undergo complete examination for exclusion of pre-existing venous deep thrombosis and
coagulopathies.

Published: April 2018

This research aims to classification of samples of green tea and black tea originated from different planting sites, Tambi and Pagilaran. Samples of green tea and black tea; quality I (BOP), quality II (BP), quality III (Bohea) were each collected from Tambi and Pagilaran to analyze the charasteristic of both sample from both sites. Measurements of tea samples were performed using a dynamic e-nose device based on a MOS gas sensor, with a maximum set point temperature of 40ºC, flushing 300 seconds, collecting 120 seconds, and purging 80 seconds for 10 cycles repeatedly. The resulting sensor response is then processed using the difference method for baseline manipulation. Characteristic of extraction process on the sensor response results is carried out in three methods; relative, fractional change, and integral. Matrix data of the feature extraction results was reduced using the PCA method by mapping the aroma patterns of each sample using 2-PCA components. The PCA reduction results in integral feature extraction showed the largest percentage of cumulative variance in classifying green tea sample data by 97% and black tea by 100%. The large percentage value of cumulative variance indicates PCA can differentiate samples of green tea and black tea from Tambi and Pagilaran well.
PERTUMBUHAN STEK HORIZONTAL BATANG JARAK PAGAR (Jatropha curcas L.) YANG DIINTRODUKSI DENGAN PSEUDOMONAD FLUORESEN
Authors: Advinda Linda 
Published: April 2018

Jatropha curcas L. is one of the plants that can be developed as raw material of biodiesel. One of the efforts to increase the production of J. curcas is the propagation of stem cuttings horizontally. Efforts to stimulate root growth can be accomplished by adding Plant Growth Regulators (PGRs). PGRs can be obtained naturally or synthetically. Indole acetic acid (IAA) is one of PGRs, which is not only produced by plants but can also be produced by rhizobacteria. One such rhizobacteria is fluorescent pseudomonad. The objectives of the study were to know the response of growth of horizontal stem cuttings after being introduced with fluorescent pseudomonad. This research is an experimental research. Complete Randomized Design with 6 treatments and 4 replications. The treatments were soaking of J. curcas stem cuttings with fluorescent pseudomonad isolate suspension PfPj3 suspension concentration of 0% (without suspension), 5%, 10%, 15%, 20%, and 25%. Observation of the research is the beginning of the shoots, the number of shoots, and the length of the J. curcas stem shoot. The data obtained were analyzed using Anova and DNMRT significant level of 5%. The results showed that horizontal stem cuttings of J. curcas with fluorescent pseudomonad suspension influenced early shoot, shoot number, and shoot length. A 10% fluorescent pseudomonad concentration can cause shoots to appear early, while a concentration of 20% causes the largest number of shoots.

Hyperchaos, adaptive control and synchronization of a novel 5-D hyperchaotic system with three positive Lyapunov exponents and its SPICE implementation
Authors: Vaidyanathan Sundarapandian , Volos Christos , Pham Viet-Thanh 
Published: May 2018

Abstract
In this research work, a twelve-term novel 5-D hyperchaotic Lorenz system with three quadratic nonlinearities has been derived by adding a feedback control to a ten-term 4-D hyperchaotic Lorenz system (Jia, 2007) with three quadratic nonlinearities. The 4-D hyperchaotic Lorenz system (Jia, 2007) has the Lyapunov exponents L1 = 0.3684,L2 = 0.2174,L3 = 0 and L4 =−12.9513, and the Kaplan-Yorke dimension of this 4-D system is found as DKY =3.0452. The 5-D novel hyperchaotic Lorenz system proposed in this work has the Lyapunov exponents L1 = 0.4195,L2 = 0.2430,L3 = 0.0145,L4 = 0 and L5 = −13.0405, and the Kaplan-Yorke dimension of this 5-D system is found as DKY =4.0159. Thus, the novel 5-D hyperchaotic Lorenz system has a maximal Lyapunov exponent (MLE), which is greater than the maximal Lyapunov exponent (MLE) of the 4-D hyperchaotic Lorenz system. The 5-D novel hyperchaotic Lorenz system has a unique equilibrium point at the origin, which is a saddle-point and hence unstable. Next, an adaptive controller is designed to stabilize the novel 5-D hyperchaotic Lorenz system with unknown system parameters. Moreover, an adaptive controller is designed to achieve global hyperchaos synchronization of the identical novel 5-D hyperchaotic Lorenz systems with unknown system parameters. Finally, an electronic circuit realization of the novel 5-D hyperchaotic Lorenz system using SPICE is described in detail to confirm the feasibility of the theoretical model.
Suggesting Śāntarasa in Shanti Mandir’s Satsaṅga: Ritual, Performativity and Ethnography in Yogaland
Authors: Mccartney Patrick 
Published: May 2018

Abstract
Satsaṅga is a public domain where ideas related to transcendence and culturallycontingent “Truth” are suggested. This paper combines a longitudinal study of Shanti Mandir’s (www.shantimandir.com) satsaṅga, with close reading of local and non-local literary theories related to the performativity of satsaṅga and the doctrine of appreciating tranquillity (śāntarasavāda). This leads to the possibility of framing satsaṅga as a rasavatkāvya (charming-literature) literary artefact; which we can regard as a type of hybrid campū-rasavat kāvya. Finally, from an interdisciplinary perspective, I provide a novel epistemological bricolage to understand the soteriological and sociological aims of satsaṅga from within the Temple of Peace (Shanti Mandir) organisation, and propose an analytical framework about how satsaṅga operates as a formal learning domain; where sādhaka-s (aspirants) attempt to gain access to a yoga-inspired disposition related to becoming (praśama), embodying and experiencing śānti (tranquillity), which occurs through learning to become śāntamūrti-s (embodiers of tranquillity) by appreciating śāntarasa (the aesthetic mood of tranquillity).

Published: April 2018

In this article, we present the challenges faced by journalists who interviewed lesbians, gays, bisexuals, transgenders and intersexuals (LGBT) to construct narratives and understand the vulnerability that these people must live with, as well as the listening challenges that this process represents. We present a field investigation based on the method of reporting and interview three journalists, understanding their renditions of reports and books they have written on the issue, and elaborating a discussion on the “Sign of Relation”; in other words, how alterity, complexity and complicity can be achieved in journalistic practice; elements that are capable of stimulating authorship and recognizing the differences and inequalities built around gender and sexuality in our societies. No presente texto, apresentamos os desafios de jornalistas que vão ao encontro de lésbicas, gays, bissexuais, travestis, intersexuais e homens e mulheres transexuais (LGBT) para construir narrativas com o devido respeito e compreensão das dimensões de vulnerabilidade em torno da vida dessas pessoas e os desafios de escuta que esse processo representa. Apresentamos uma investida de campo, por meio do método da reportagem, na qual assinalamos as interpretações de três jornalistas sobre seus livros-reportagem com temática LGBT para elaborar uma discussão sobre o “Signo da Relação”, isto é, quais são os caminhos possíveis para alcançar alteridade, complexidade e cumplicidade na prática jornalística, elementos capazes de estimular a autoria e o devido reconhecimento das diferenças e desigualdades construídas em torno do gênero e da sexualidade em nossas sociedades.En este artículo, presentamos los desafíos de periodistas que van al encuentro de lesbianas, gays, bisexuales, travestis, intersexuales y hombres y mujeres transexuales (LGBT) para construir narrativas con el debido respeto y comprensión de las dimensiones de vulnerabilidad alrededor a la vida de esas personas y los desafíos de escucha que este proceso representa.

Generating synthetic social graphs with Darwini
Authors: Edunov Sergey , Logothetis Dionysios , Wang Cheng , Ching Avery , Kabiljo Maja 
Published: April 2018

Synthetic graph generators facilitate research in graph algorithms and graph processing systems by providing access to graphs that resemble real social networks while addressing privacy and security concerns. Nevertheless, their practical value lies in their ability to capture important metrics of real graphs, such as degree distribution and clustering properties. Graph generators must also be able to produce such graphs at the scale of real-world industry graphs, that is, hundreds of billions or trillions of edges.In this paper, we propose Darwini, a graph generator that captures a number of core characteristics of real graphs. Importantly, given a source graph, it can reproduce the degree distribution and, unlike existing approaches, the local clustering coefficient distribution. Furthermore, Darwini maintains a number of metrics, such as graph assortativity, eigenvalues, and others. Comparing Darwini with state-of-the-art generative models, we show that it can reproduce these characteristics more accurately. Finally, we provide an open source implementation of Darwini on the vertex-centric Apache Giraph<sup>TM</sup>&nbsp;model that can generate synthetic graphs with up to 3 trillion edges.
