Published: April 2017

Nowadays, face recognition systems are going to widespread in many fields of application, from automatic user login for financial activities and access to restricted areas, to surveillance for improving security in airports and railway stations, to cite a few.
In such scenarios, the architectures based on stereo vision and 3D reconstruction of the face are going to assume a predominant role because they can generally assure a better reliability than solutions based on a single camera (which make use of a single image instead of a couple of images). To realize such systems, different architectures can be considered by varying the positioning of the pair of cameras with respect to the face of the subject to be identified, as well as both kind and resolution of camera considered. These parameters can affect the correct decision rate of the system in classifying the input face, especially in presence of image uncertainty.
In this paper, several 3D architectures differing in camera specifications and geometrical positioning of the camera pair (with respect to the input face) are realized and compared. The detection of facial features in the images is made by adopting a popular method based on the Active Appearance Model (AAM) algorithm. 3D position of facial features is then obtained by means of stereo triangulation. The performance of the realized systems has been compared in terms of sensitivity to the quantities of influence and related uncertainty, and of typical indexes for the analysis of classification systems. Main results of such comparison show that the best performance can be reached by reducing the distance between cameras and subject to be identified and by minimizing the horizontal angle between the plane containing the camera pair axis and the face to be identified.
Apropriação Simbólica (e Senhorial!) da Natureza na Península Ibérica (século IV-VIII)
Authors: Bastos Mario Jorge Da Motta
Published: April 2017

Proponho-me, no presente artigo, a abordar a concepção denatureza e das relações travadas pelos homens com este seu “laboratório inorgânico de existência” expressa em fontes diversas elaboradas no contexto da Sociedade Ibérica do século IV ao VIII. Ver-se-á a difusão, no período em questão, de uma concepção de natureza como obra da Criação e concessão divinaem usufruto humano, tornando-a dom de uma divindade  suprema que institui, na base da sua própria ação original, oelemento primário da submissão irrevogável destes ao dominus celestial. Traduzindo-a em uma expressão, a concepção cristã de mundo (e de natureza, pois) veiculada pelas elites ibéricas fundamentou-se, concentrou-se e se articulou em torno do exercício e da manifestação de poder, inserindo a divindade no curso da história e, a partir dessa inserção, desvelando uma ordem social e sagrada calcada em vínculos pessoais, dependências, fidelidades,poder e submissão.

Published: April 2017

An immobilized biological filter (IBF) using Fe(II) and Mn(II) as mixed electron donors was evaluated for nitrate removal in groundwater. Results of the single factor experiments of strain SZ28 under the conditions of electron donor:electron acceptor ratio (1:2, 1.45:1, 3:1), Fe(II):Mn(II) ratio (1:9, 3:7, 5:5) demonstrated that the highest nitrate removal ratio was 100%, 49.6% (Mn(II)) and 100% (Fe(II)) under the conditions of electron donor:electron acceptor ratio of 3:1, Fe(II):Mn(II) ratio of 5:5. Mn(II) and Fe(II) as electron donor was tested for the effects on denitrification in the IBF reactor. Optimal conditions were obtained at an electron donor:electron acceptor ratio of 2:1, hydraulic retention time of 12 h and Fe(II):Mn(II) ratio of 5:5 with the highest removal ratio of nitrate-N (100%), Mn(II) (50.25%) and Fe(II) (99.2%). Results suggest that the optimal condition obtained from the IBF was feasible.

Kratom and Future Treatment for the Opioid Addiction and Chronic Pain: Periculo Beneficium?
Authors: Ismail Ismaliza , Wahab Suzaily , Sidi Hatta , Das Srijit , Lin Loo Jiann , Razali Rosdinom
Published: April 2017

Kratom (Mitragyna speciosa), a naturally existing plant found in South-East Asia, is traditionally
used as a herb to help elevate a person’s energy and also to treat numerous medical ailments.
Other than the analgesic property, kratom has been used as an agent to overcome opioid withdrawal as
it contains natural alkaloids, i.e. mitragynine, 7-hydroxymitragynine, and MGM-9, which has agonist
affinity on the opioid receptors, including mu (µ) and kappa (κ). The role of neural reward pathways
linked to µ-opioid receptors and both dopaminergic and gamma-Aminobutyric acid (GABA)-ergic
interneurons that express µ-opioid receptors were deliberated. However, kratom has been reported to
be abused together with other illicit substances with high risk of potential addiction. There are also
anecdotes of adverse effects and toxicity of kratom, i.e. tremor, fatigue, seizure, and death. Different
countries have distinctive regulation and policy on the plantation and use of this plant when most of
the countries banned the use of it because of its addiction problems and side effects. The aim of this
review is to highlight on the potential use of kratom, unique ‘herbs” as a substitution therapy for
chronic pain and opioid addiction, based on the neurobiological perspective of pain and the underlying
mechanism of actions of drug addiction.

Authors: Dhara Deboleena , Sunil Dhanya , Kamath Pooja R. , Ananda K. , Shrilakshmi S. , Balaji S.
Published: April 2017

Introduction:

The escalating threat due to dwindling effect of antibiotics and challenge
of tackling rising drug-resistant infections has gathered high focus in current medicinal research.

Methods:

In an attempt to find new molecules that can defeat microbial resistance, two new series
of 2-[2-substituted ethenyl]-5-(substituted methoxy)-1,3,4-oxadiazole derivatives were synthesized.
Various aromatic hydrazides were allowed to undergo cyclization to substituted oxadiazole-2-
amines in the presence of cyanogen bromide and further condensed with different heterocyclic aldehydes
to give new oxadiazole derivatives. The synthesized molecules were fully characterized by
various spectral techniques and tested for antimicrobial activity.

Results:

Almost all the newly synthesized compounds especially (5g-5l) displayed remarkable
growth inhibition against three bacterial strains: M. smegmatis, S. aureus, E. coli and fungi C. albicans.
The antimicrobial activity was further confirmed by MIC assay against the same microorganisms.
Oxadiazole 5g displayed promising activity with a MIC value of 0.025 mM for two bacteria
and fungi, whereas MIC of this compound for E. coli was 0.1 mM. Other active compounds (5h-5l)
also exhibited good MIC ranging between 0.313 to 5.0 mM against the selected microorganisms.
Docking simulations were generated to explore the potential binding approaches of ligand 5g at the
D-alanine:d-alanine ligase (Ddl) protein of E. coli and S. aureus.

Conclusion: Molecule 5g was active even at a lower concentration and could probably act as a
prospective lead molecule for targeting the drug resistant microorganisms.

Primaquine (PQ) is a key drug in the malaria pre-elimination stage. However, PQ can trigger acutehemolysis for people with G6PD defciency (G6PDd). In 2013, 15–25 million Indonesian people were infected with malaria, with 30,000–38,000 deaths each year mostly in eastern Indonesia with API= 15.6 %. Recently, the Ministry of Health of the Republic of Indonesia announced a plan to reach the pre-elimination stage based on WHO guidelines. This study assesses whether eastern Indonesia should proceed with the activities of malaria pre-elimination. A total 555 healthy people in fve subdistricts in eastern Indonesia were selected by systematic random samping. All data were collected using a standard questionnaire, physical examination, and laboratory tests. PCR and DNA sequencing protocols followed respective manufacture’s instructions. Statistical analysis by bivariate with α= 0.05 and 95% CI were performed using the SPSS software package. Based on the nested PCR, the result showed a malaria prevalence of 32.6% with being the dominant species (52.5%). Malaria cases were found in all study sites and not using a bed net was the moost signifcant risk factors with Exp B= 1.54 with 95% CI= 0.99–2.38. G6PDd prevalence was 16.6%, the highest G6PDd ever found in Indonesia with variant molecular dominant 10.883 T>C and one sample with a heterozygous female. Malaria pre-elimination in eastern Indonesia should be delayed. High risk patients should be tested for enzyme G6PD activities before antimalarial administration.
The effect of methanol extract of soybean seeds (Glycine max L.Merr.) on the histology and immunohistochemical distribution of Cyp19 aromatase in rat testis (Rattus norvegicus L.)
Authors: Aryani Retno , Moeljopawiro Sukarti , Nugroho Laurentius Hartanto , Astuti Pudji
Published: April 2017

Soybean (Glycine max L. Merr.) contains phytoestrogens that have a chemical structure resembling estrogen in the body. They function like estrogen and antiestrogen, affecting the metabolism of sex steroid hormones. This research aimed to determine the effect of the methanol extract of soybean on the histological structure and distribution of immunohistochemical Cyp19 aromatase in rat testis . Twenty males of Wistar rats were divided into 4 groups of 5. The frst group was the control and the second to fourth groups were given soybean extract (250 mg/kg of body weight, 500 mg/kg of body weight) and genistein (0.3 mg/kg of body weight), respectively, for 52 days. The results of this study indicate that the effect of methanol extract from soybean caused weight gain, and the weight of the testis and epididymis decreased. In addition, the histological results showed that seminiferous tubules were reduced in size, became irregular, were separated by a wide interstitium, and spermatogenic cells were decreased. The immunohistochemical results showed that the expression of Cyp19 aromatase in the rats decreased both in spermatocyte cells and Leydig cells. It could be concluded that the methanol extract of soybean induced testicular damage and reduced Cyp19 aromatase expression in rat testis.
Detection and identifcation of adherence genes of intestinal-origin Lactobacillus and Pediococcus strains grown on gastric mucin in vitro
Authors: Widodo W. , Lestari Sri , Asmara Widya
Published: April 2017

One of the primary selection criteria for potential probiotics is the ability to adhere to the host gastrointestinal tract. This study evaluated the in vitro adhesion ability on gastric mucin of two Lactobacillus casei strains (AP and AG) and two Pediococcus acidilactici strains (BE and BK), and identifed the corresponding genes responsible for adherence. Adhesion assays were performed in 96-well polystyrene microtiter plates using gastric mucin from porcine stomach as the matrix. An in vitro study on gastric mucin revealed that lactobacilli had a greater adherence ability compared with pediococci strains. The potential adherence genes were investigated using polymerase chain reaction (PCR) technology. Using specifc primers, PCR studies amplifed 150 base pairs of a potential mub gene and 161 base pairs of a potential ef-Tu gene, but no amplifed bands for potential map and bac genes were obtained. Sequence comparisons showed that the 150 and 161 amplifed base pairs were respectively homologous to the mub of Pediococcus acidilactici and ef-Tu genes of Lactobacillus paracasei. We concluded that the adherence ability of two strains of Lactobacillus casei (AP and AG) and two strains of Pediococcus acidilactici (BE and BK) on gastric mucin is in accordance with the presence of ef-Tu and mub genes. High level attachment in lactobacilli is likely to correlate with the ef-Tu gene, which is a lactobacilli-specifc adhesive gene.
O DESPERDÍCIO DE ALIMENTOS: UM ESTUDO DE CASO NA CEASA SERRA-RS
Authors: Philereno Deivis Cassiano , Dalegrave Josué
Published: April 2017

O objetivo geral é identificar o destino das sobras dos alimentos hortifrutigranjeiros da CEASA Serra, no primeiro semestre de 2015. Para a realização da pesquisa utilizou-se o método exploratório com abordagens qualitativa e quantitativa, por meio de entrevista semiestruturada e questionário estruturado. As entrevistas foram realizadas com o Secretário da Agricultura e com o Gerente da CEASA Serra, já o questionário foi aplicado para 17 comerciantes da CEASA. Na análise qualitativa, observou-se a falta de programas de destinação das sobras dentro da instituição, de investimento do poder público, a desinformação do comerciante e a falta de interlocução entre os envolvidos nesse processo. Por sua vez, na análise quantitativa, constatou-se que 13 dos 17 entrevistados gostariam de doar as suas sobras para um banco de alimentos, pois na concepção dos entrevistados, a própria estrutura da CEASA Serra, não oferece o suporte necessário para que haja menos desperdício de alimentos.
A DINÂMICA DA PRODUÇÃO E REPRODUÇÃO SOCIAL DOS PRODUTORES DE MAMONA VINCULADOS AO PROGRAMA NACIONAL DE PRODUÇÃO E USO DE BIODIESEL
Authors: Loreto Maria das Dôres Saraiva de , Calvelli Haudrey Germiniani , Silva Érika Cristine
Published: April 2017

O presente trabalho examina a dinâmica da produção e reprodução social dos arranjos produtivos de mamona, na Região Nordeste do Brasil. A pesquisa fez uso do método survey, entrevistando 50 agricultores, vinculados ao Programa Nacional de Produção e Uso de Biodiesel (2012-2015). Resultados mostraram que, apesar de o programa ter potencializado maior adensamento societário, por meio do Selo Combustível Social e do Projeto de Polos de Produção de Biodiesel, os agricultores familiares da Região Nordeste têm enfrentado problemas para transformar a produção de mamona, em grande parte extrativa, em um cultivo organizado, por estarem inseridos em uma agricultura de subsistência, com pouco conhecimento técnico e gerencial. Conclui-se que a produção do biodiesel pela agricultura familiar somente poderia fomentar a formação de arranjos produtivos locais sustentáveis, caso as ações do PNPB estivessem atreladas a outras políticas sociais, tecnológicas e ambientais.

Electrochemical characterisation of novel screen-printed carbon paste electrodes for voltammetric measurements
Authors: Sýs Milan , Khaled Elmorsy , Metelka Radovan , Vytřas Karel
Published: April 2017

This work is focused on the homemade screen-printed carbon paste electrode containing basically graphite powder (or glassy carbon powder), poly(vinylbchloride) (PVC) and paraffin oil. It compares the electrochemical properties of conventional carbon-based electrodes and prepared screen-printed carbon paste electrodes towards [Fe(CN)6]3-/[Fe(CN)6]4- and quinone/hydroquinone redox couples. Significant attention is paid to the development of the corresponding carbon inks, printing and the surface characterisation of the resulting electrodes by the scanning electron microscopy. An optimization consisted of the selection of the organic solvent, the optimal content of the used polymer with the chosen paste binder, appropriate isolation of electric contact, etc. Very similar properties of the prepared screen-printed electrodes, containing only corresponding carbon powder and 3 % PVC, with their conventional carbon paste electrode and glassy carbon-based electrodes, were observed during their characterisation. Screen-printed electrodes, with the pasting liquid usually provided satisfactory analytical data. Moreover, they can be used in the flow injection analysis and could undoubtedly replace the carbon paste grooved electrodes. It can be assumed that certain progress in the development of electrode materials was achieved by this research.

Published: April 2017

Pd-catalysed arylation?acetoxylation cascade, a previously reported methodology, was applied in the functionalisation of unsymmetrical dienes. Both explored classes of compounds, isoquinoline and ?-carboline-derived dienes, afforded single regioisomers. Although further improvements of the process are necessary, primarily due to lower yields, the described functionalisation of the studied compounds might be useful in the synthesis of emetine and related naturally occurring compounds.
Analysts' Influence on Managers' Guidance
Authors: Chapman Kimball , Green Jeremiah R.
Published: April 2017

Analysts ask managers for forward-looking information in one-third of quarterly conference calls; most frequently, seeking earnings per share guidance. In this study, we examine the long-term consequences of analysts' questions on future manager disclosure choices. Using six types of commonly provided guidance, we find that when analysts request new guidance or ask about prior guidance, managers are more likely to provide similar guidance in future quarters. When analysts do not ask about prior guidance, managers are less likely to provide that type of guidance in the future. This effect is long-lasting, spills over into earnings announcements, and is strongest for firms with the most severe information problems. Our results provide evidence that analysts shape managers' disclosure choices in meaningful ways.
Audit Sampling Using Benford's Law: A Review of the Literature with Some New Perspectives
Authors: Nigrini Mark J.
Published: April 2017

Accounting studies have used the premise that nonconformity to Benford's Law (hereafter, Benford), which gives the expected patterns of the leading digits in numerical data, is a red flag for fraud. This study reviews Benford's Law and divides the accounting applications into five categories. A proposed Benford-based audit sampling method, which selects as the audit sample the set of transactions or balances that needs to be removed from the audit population to leave a remainder that conforms to Benford, is reviewed and reexamined. The finding is that the method, as advocated, can generate large audit samples and that the accuracy rate is questionable, even when known errors are seeded into the data. The study then reviews some new perspectives on using Benford's Law in auditing by reviewing (1) the mathematical bases for expecting Benford conformity, (2) the type of auditee data that are appropriate for Benford-based sampling, (3) various options to limit the sample size, and (4) the limitations of a Benford-based sampling approach. These perspectives draw on some facts related to the way in which the HealthSouth Corporation financial statement fraud was executed.

In the body, 2-methoxyethanol compound may be converted to MAA. MAA is a strong oxidant and may cause oxidation stress in spermatozoa. Oxidation stress is a disturbance on phosphorilation that increases ROS concentration, and it produces lipid peroxide in spermatozoa membrane resulted in high MDA concentration. One of indicator of spermatozoa membrane disturbances is a lack of spermatozoa membrane integrity. The main purpose of this research was to determine the relationship between MDA concentration in sperm and membrane integrity of spermatozoa in rats. The animal of treated groups (n = 40) were divide into 8 groups of 5 each. The rats were given subcutaneous injection with 0,2 ml of 200 mg/kg/day for 1 day (P1), 3 days (P2), 6 days/week (P3), and 12 days/two weeks (P4), respectively the control group was injected with physiological saline of the same volume. The concentration of MDA was measured by spectrophotometer and observing membrane integrity used HOS method to watch the spermatozoa response on hypoosmotic condition. The results of the research indicated that 2-ME caused the increasing in sperm MDA concentration and the decrease of spermatozoa membrane integrity. There was negative correlations between MDA concentration and spermatozoa membrane integrity.

Traços vivos: jogos de cenas nas (im)possíveis dobras da escrita na pesquisa em educação (Matemática)
Authors: Marim Márcia Maria Bento , Farias Kátia Sebastiana Carvalho dos Santos
Published: April 2017

Este texto tem por objetivo mobilizar exemplos de práticas de escrita no estilo de ‘jogos de cenas’ constituídos sob um ponto de vista teórico-metodológico inspirado nos modos de filosofar de Ludwig Wittgenstein e Jacques Derrida.  Esta mobilização se utiliza do entrelaçamento das noções de ‘jogos de linguagem’ de Wittgenstein e ‘escritura’ de Derrida para possibilitar o entendimento do ato de escrita da pesquisa científico-acadêmica como atos narrativos que envolvem a encenação corporal das práticas culturais da escrita e da fala, verbais e não verbais, isto é, a ação de corpos humanos e não humanos orientados por gramáticas diferenciadas e idiossincráticas em uma performance da linguagem. Com o propósito de exemplificar um possível modo de como pode-se constituir jogos de cenas nesta perspectiva fizemos uso de ‘recortes’ e ‘colagens’.  Por ‘recorte’ queremos significar a retirada de um enunciado (proferimento) do contexto em que ele é enunciado. Por ‘colagem’ queremos significar a sua inserção em um novo contexto, naquele em que reaparece. É este duplo movimento diferencial que o nosso ver derridiano-wittgensteiniano caracteriza o ato da citação e é essa citação que recoloca em ação o enunciado performativo que opera neste estilo de escrita que vem abrindo espaços para modos outros de se proceder à constituição do texto cientifico-acadêmico na história da educação (matemática): a escrita dialógica.Palavras-chave: Jogos de Cenas.

Does Fall Arrest Strategy Training Added to a Fall Prevention Programme Improve Balance, Strength, and Agility in Older Women? A Pilot Study
Authors: Arnold Cathy M. , Walker-Johnston JoAnn , Lanovaz Joel L. , Lattimer Lauren J.
Published: April 2017

Purpose: The purpose of this study was to determine the effect of a unique exercise programme (Fall Arrest Strategy Training, or FAST) on upper body strength, range of motion (ROM), and fall risk in older women. FAST was designed to improve upper body capacity to prevent injury when a fall cannot be avoided. Method: A quasi-randomized site design included 71 older women (aged 67–95 y, mean age 83 years), who participated either in a standard fall prevention programme (Staying on Your Feet, or SOYF; n=29) or in SOYF combined with FAST (n=42). The women were measured three times—at baseline, after the 12-week intervention, and again 12 weeks later—for upper body strength, ROM, and fall risk factors (fall risk questionnaire, balance, mobility, and leg strength). Results: No significant differences were found in age, physical activity, or cognitive or functional status between the SOYF–standard and the SOYF–FAST groups. Both groups improved their fall risk status after the intervention, with no significant differences between them; however, the SOYF–FAST group showed greater improvements in upper extremity strength and ROM (p=0.007). Conclusion: FAST can feasibly be integrated into fall prevention programming, with additional gains in upper body strength and ROM in older women.

Three new compounds, xenorine A-C, along with six known compounds were isolated from the cultured broth of Xenorhabdus indica. The chemical structures of these compounds were elucidated mainly by analysis of 1D and 2D NMR and MS data. The major metabolites were dioxopiperazines. In addition, 5,6,11,11a-tetrahydro-1 H-imidazo[1′,5′:1,6]pyrido[3,4- b]indole-1,3(2 H)-dione, previously described as synthetic product, was isolated as a natural product. The absolute configuration was determined using quantum chemical time-dependent density functional theory calculations. The six known compounds showed weak in vitro immunosuppressive activity towards concanavalin-A- and lipopolysaccharide -induced proliferation of mice splenocytes.
Intensity and the Missing Virtual: Deleuze's Reading of Spinoza
Authors: Voss Daniela
Published: April 2017

Deleuze's interpretation of Spinozan philosophy is intrinsically related to the concept of intensity. Attributes are defined as intensive qualities, modal essences as intensive quantities or degrees of power; the life of affects corresponds to continuous variations in intensity. This essay will show why Deleuze needs the concept of intensity for his reading of Spinozan philosophy as a philosophy of expressive immanence. It will also discuss the problems that spring from this reading: in what way, if any, are modal essences modified by the intensive variations of affects? How can the Spinozan conception of eternal modal essences be reconciled with the idea of affections of essence? What is the ethical import of the life of existing modes, when modal essences are considered as eternal? While these questions, in particular the last two, confront each commentator on Spinoza and demand a solution in one way or another, the essay will conclude with a question which is posed from an exclusively Deleuzian perspective: why is the concept of the virtual, which takes centre stage in Deleuze's own philosophy of immanence, missing in his account of Spinoza?
Tracking the Triple Form of Difference: Deleuze's Bergsonism and the Asymmetrical Synthesis of the Sensible
Authors: Lundy Craig
Published: April 2017

This paper will explore the notions of intensity, the virtual/actual and different/ciation in Gilles Deleuze's work. It will focus in particular on excavating the Bergsonian dimension of these terms in Deleuze's philosophy and their relations to one another. While much has been written on the role of Bergson in shaping Deleuze's virtual/actual philosophy, far less attention has been paid to the way in which Deleuze's thoughts on intensity and the movements of different/ciation are also developed out of his reading of Bergson. To address this I will explicate the ‘triple form of difference’ that Deleuze locates in Bergson, which includes renditions of intensity and the process of differentiation, after which I will map the movements from this early Bergsonian work to Deleuze's mature position on the matter, as it is found in the final chapter of Difference and Repetition.
Intensity in Context: Thermodynamics and Transcendental Philosophy
Authors: Clisby Dale
Published: April 2017

Deleuze's use of thermodynamics in the fifth chapter of his masterwork Difference and Repetition ushers in perhaps the most crucial notion for understanding this work: intensity. Given that the process of actualisation relies on the intensive necessarily means that any discussion of the relationship between the virtual and the actual must include a thorough explanation of the role of intensity, and where exactly this notion sits within the virtual–actual doublet. As such, we must return to the fifth chapter of Difference and Repetition in order to assess the way in which Deleuze conceives of this complex and indispensable cog in his ontological and metaphysical philosophy. In this paper we turn, then, to Deleuze's engagement with the theories of the intensive as found in classical thermodynamic theory. Quite simply, Deleuze will highlight the way in which the productive force of differences in intensity remains under-appreciated in contrast to the extensive states they create in this classical framework. We can understand this engagement, then, as an example of the way in which the extensive is continually privileged over the intensive. In this paper we will outline the details of the engagement between Deleuze and thermodynamics, as this paves the way for his own philosophy of intensity. Furthermore, we will provide a theory of the relationship between intensity, the virtual and the actual as these notions appear in Difference and Repetition.
Deleuze's Concept of Quasi-cause
Authors: Roffe Jon
Published: April 2017

The concept of quasi-cause is a relatively marginal one in the work of Gilles Deleuze, appearing briefly in The Logic of Sense and then Anti-Oedipus three years later. In part because of this marginality – the meagre degree to which it is integrated into the respective metaphysical system of the two works – it provides us with a useful vantage point from which to examine these systems themselves. In particular, a careful exposition of the two forms that the concept of the quasi-cause takes provides us with an aperture on the shifting role of the concepts of the virtual and the intensive in Deleuze's ongoing project. In this paper, I will argue that, through this aperture, it is possible to see the displacement of the virtual in favour of the intensive. In turn, we can characterise Anti-Oedipus as the birth of a fully actualist Deleuzian metaphysics.
Environmental Effects on the Polypyrrole Tri-layer Actuator
Authors: Masurkar Nirul , Jamil Kawsar , Arava Leela
Published: April 2017

Electroactive polymer actuators such as polypyrrole (PPy) are exciting candidates to drive autonomous devices that require low weight and low power. A simple PPy tri-layer bending type cantilever which operates in the air has been demonstrated previously, but the environmental effect on this actuator is still unknown. The major obstacle in the development of the PPy tri-layer actuator is to create proper packaging that reduces oxidation of the electrolyte and maintains constant displacement. Here, we report the variation in the displacement as well as the charge transfer at the different environmental condition. PPy trilayer actuators were fabricated by depositing polypyrrole on gold-coated porous poly(vinylidene fluoride) (PVDF) using the electro-synthesis method. It has been demonstrated that the charge transfer of tri-layer actuators is more in an inert environment than in open air. In addition, tri-layer actuators show constant deflection and enhancement of life due to the negligible oxidation rate of the electrolyte in an inert environment.

In this paper, wool carpet dye adsorption properties of nanoporous activated carbon materials (NCMs) prepared from bamboo agro-product is reported. Bamboo cane powder was chemically activated with phosphoric acid at different temperatures (400, 500, and 600 °C) at an impregnation ratio of 1:1. We found that the specific surface area and the total pore volume of NCM increases with temperature giving the highest surface area and pore volume ca. 2130 m2·g−1 and 2.69 cc·g−1 at 600 °C. Owing to superior surface textural properties, bamboo-derived NCM showed excellent adsorption capacity for wool carpet dyes Lanasyn orange (LO) and Lanasyn gray (LG). The adsorption phenomena could be described by Langmuir/Freundlich adsorption isotherm models. The maximum adsorption capacity was ca. 2.60 × 103 and 3.04 × 103 mg·g−1 for LO and LG, respectively. The adsorption followed pseudo second order kinetics with the second order rate constant of 1.24 × 10−3 g·mg−1·min−1 (LO) and 7.69 × 10−4 g·mg−1·min−1 (LG), respectively. This study demonstrated that the high surface area NCMs prepared from agro-product can be used as efficient and cost-effective adsorbent materials for the removal of dyes from industrial effluent.
HER2 in Breast Cancer Stemness: A Negative Feedback Loop towards Trastuzumab Resistance
Authors: Nami Babak , Wang Zhixiang
Published: April 2017

HER2 receptor tyrosine kinase that is overexpressed in approximately 20% of all breast cancers (BCs) is a poor prognosis factor and a precious target for BC therapy. Trastuzumab is approved by FDA to specifically target HER2 for treating HER2+ BC. However, about 60% of patients with HER2+ breast tumor develop de novo resistance to trastuzumab, partially due to the loss of expression of HER2 extracellular domain on their tumor cells. This is due to shedding/cleavage of HER2 by metalloproteinases (ADAMs and MMPs). HER2 shedding results in the accumulation of intracellular carboxyl-terminal HER2 (p95HER2), which is a common phenomenon in trastuzumab-resistant tumors and is suggested as a predictive marker for trastuzumab resistance. Up-regulation of the metalloproteinases is a poor prognosis factor and is commonly seen in mesenchymal-like cancer stem cells that are risen during epithelial to mesenchymal transition (EMT) of tumor cells. HER2 cleavage during EMT can explain why secondary metastatic tumors with high percentage of mesenchymal-like cancer stem cells are mostly resistant to trastuzumab but still sensitive to lapatinib. Importantly, many studies report HER2 interaction with oncogenic/stemness signaling pathways including TGF-β/Smad, Wnt/β-catenin, Notch, JAK/STAT and Hedgehog. HER2 overexpression promotes EMT and the emergence of cancer stem cell properties in BC. Increased expression and activation of metalloproteinases during EMT leads to proteolytic cleavage and shedding of HER2 receptor, which downregulates HER2 extracellular domain and eventually increases trastuzumab resistance. Here, we review the hypothesis that a negative feedback loop between HER2 and stemness signaling drives resistance of BC to trastuzumab.

Published: April 2017

Despite advances in psychological interventions for pediatric chronic pain, there has been little research examining mindfulness meditation for these conditions. This study presents data from a pilot clinical trial of a six-week manualized mindfulness meditation intervention offered to 20 adolescents aged 13–17 years. Measures of pain intensity, functional disability, depression and parent worry about their child’s pain were obtained at baseline and post-treatment. Results indicated no significant changes in pain or depression, however functional disability and frequency of pain functioning complaints improved with small effect sizes. Parents’ worry about child’s pain significantly decreased with a large effect size. Participants rated intervention components positively and most teens suggested that the number of sessions be increased. Three case examples illustrate mindfulness meditation effects and precautions. Mindfulness meditation shows promise as a feasible and acceptable intervention for youth with chronic pain. Future research should optimize intervention components and determine treatment efficacy.
Ride Quality Due to Road Surface Irregularities: Comparison of Different Methods Applied on a Set of Real Road Profiles
Authors: Loprencipe Giuseppe , Zoccali Pablo
Published: April 2017

Road roughness evaluation can be carried out using different approaches. Among these, the assessment of ride quality level perceived by road users is one of the most-used. In this sense, different evaluation methods have been developed in order to link the level of irregularities present on road surface profiles with the induced detrimental effects in terms of discomfort. In particular, relationships between wavelength content of road profiles and consequent level of comfort perceived had been investigated by using, in general, a mean panel ratings approach. In this paper, four ride quality evaluation methods (Ride Number, Michigan Ride Quality Index (RQI), Minnesota Ride Quality Index and frequency-weighted vertical acceleration, awz, according to ISO 2631 were applied to a set of real road profiles. The obtained results were analyzed, investigating a possible relation between the different indices, comparing them also with the most-used road roughness method worldwide: the International Roughness Index (IRI). The analyses carried out in this work have highlighted how the various rating scales may lead to a different ride quality assessment of the same road pavements. Furthermore, comparing the awz with the values obtained for the other three methods, it was found that their rating scales are set for speeds within the range 80–100 km/h. For this reason, it is necessary to identify new thresholds to be applied for lower speeds, as in the case of urban roads. In this sense, the use of the ISO 2631 approach would seem to be a useful tool.
