Origin of Structures and Textures of some Kurdistan Marbles as Inferred from Sedimentary Ancestor Structures, NE-Iraq
Authors: Karim Kamal
Published: July 2017

The Quarries of Iraqi Kurdistan metamorphic marbles (true marble) are distributed along a belt near and parallel to the Iranian border in northeastern Iraq. These marbles associated with low-grade pelitic and calc-schist (green schist facies) and phyllite. They are formed by regional metamorphism of different types of sedimentary parent rocks in an environment not exceeded that of green schist facies (400 C and 8kb). The pelitic equivalent of the Kurdistan calcitic marble contain chlorite, albite, muscovite and biotite.In the latter years, their economic value is rapidly increased as their polished slabs extensively used for decoration purpose. The beautiful features of these marbles are consisting of sophisticated mesoscopic structures of different shapes, size and colors originated from plastic flowage and mixing of different composition and impurities reflecting either the original depositional or diageneticallyintroduced materials. Before plastic flowage they suffered from burial and tectonic fracturing which later filled with spary calcite. The origin of the marbles is analyzed according to the stage of paragenesis of the structures such as foliation, banding (layering), flow structure. The field and lab studies proved that they are all retumed to relict of primary and secondary (Nagenetic) sedimentary sttuctures. The marbles suffered from various degrees of tendency toward homogenization as the grade of regional metamorphism progressed, this reflected by mixing of foreground and background together. In addition to diffused boundary of contrasting components. Although they resemble the banded and augen gneisses but no ones formed by metamorphic differentiation. Most of the precursor structures are related to pressure solution seams and stylolites, which are combined with the triangle of Walness which deal with solution seams. Other structures are returned to lamination of the sedimentary parent rocks. Finally the probable stratigraphic unit as the original parent rocks is discussed.

Twenty seven of them gave negative reaction with 1:80 dilution, we recommend that if only Rose Bengal test is used to confirm diagnosis of brucellosis, titration of patients serum is useful for better evaluation.
EL SANTO OFICIO DE UNAMUNO EN EL TEATRO DE JOSÉ BERGAMÍN
Authors: Santa María Fernández María Teresa
Published: July 2017

La admiración de José Bergamín hacia su maestro Unamuno fue constante y manifiesta a lo largo de su vida. Son numerosos los artículos, ensayos y citas en sus poemas donde podemos encontrar la huella de don Miguel. Esa presencia adquiere unas notas particulares en el teatro del escritor madrileño: gusto por las paradojas, juego de palabras pero, sobre todo, un concepto del deber como escritores que nos les permite quedarse al margen de la realidad que les tocó a ambos vivir. Desde sus textos de Vanguardia hasta sus piezas dramáticas en el exilio la huella de Unamuno se hace patente y duradera, tal y como tendremos ocasión de comprobar.

The Use Haloperoxidases in Organic Synthesis: Selected Reactions of Oxidation, Epoxydation and Sulfoxidation
Authors: Dembitsky V.M. , Srebnik M.
Published: July 2017

Haloperoxidases are ubiquitous metalloenzymes that catalyse a variety of enantioselective oxygen-transfer reactions with hydrogen peroxide or alkylperoxides. Haloperoxidases are enzymes which catalyze the reaction of oxidation, epoxidation and sulfoxidation by hydrogen peroxide. These enzymes usually contain the FeHeme moiety or vanadium as an essential constituent at their active site, however, a few haloperoxidases which lack a metal cofactor are known. This review will examine the reactivity of the different haloperoxidases, particularly the mechanism of oxidation by hydrogen peroxide, and the mechanism of oxidation and sulfoxidation, including the newly reported regioselectivity and enantioselectivity of the haloperoxidases. The structure of chloroperoxidase, the vanadium active site and the role of critical amino acid side chains for catalysis and functional biomimetic systems, with specific relevance to the mechanism of the haloperoxidase enzymes. Advances have recently been made in using them to prepare, under controlled conditions, chiral organic molecules that are valuable for the synthesis of a wide range of useful compounds. The application of biocatalytic methods in asymmetric organic synthesis is of great interest as an alternative to chemical procedures employing chiral auxiliaries. Asymmetric oxidation of prochiral sulfides to yield optically active sulfoxides has been performed by many different techniques yielding varying enantiomeric excess values. Oxygenated metabolites are compounds that are commonly found in nature and they are produced by many different organisms. The oxygen atom is incorporated into organic compounds by enzyme-catalyzed reactions with oxygen ions as the oxygen source. For over 40 years haloperoxidases were thought to be responsible for the incorporation of mainly halogen atoms into organic molecules. However, haloperoxidases lack substrate specificity and regioselectivity, and the connection of haloperoxidases with the in vivo formation of oxygenated as well as halometabolites has been demonstrated. Recently, molecular genetic investigations showed that, at least in bacteria, fungi, and other organisms a different class of halogenases is involved in halo- and oxygenated metabolite formation. These halogenases were found to require FADH2, which can be produced from FAD and NADH by unspecific flavin reductases. The FADH2-dependent halogenases and haloperoxidases show substrate specificity and regioselectivity, and their genes have been detected in many halometabolite-producing organisms, suggesting that this type of halogenating enzymes constitutes the major source for halo- and oxygenated metabolite formation in bacteria and also in other organisms. Distribution of haloperoxidases in nature also is demonstrated in this brief review.
Theoretical Description of Polyelectrolyte Hydrogel Collapse in Electric Field
Authors: Suleimenov Ibragim , Pereladov Igor , Bekturov Esen
Published: July 2017

Theory of collapse of polyelectrolyte hydrogels under the influence of direct electric current is developed. The theory is based on the consideration of the motion of gel-solution boundary. It is shown that this boundary is moving with constant velocity on the first stage of the collapse (some part of hydrogel stayed undeformed). This velocity is theoretically determined by analysis of boundary conditions only (electric current density conservation). It is shown that on the first stage of the process hydrogel collapse caused by direct electric current is described completely by Faraday’s law analog. Hydrogel collapse is described by exponential form of Faraday’s law analog on the second stage. On this stage the whole specimen is deformed. The comparison of proposed theory and results obtained early is carried out. It is shown that the theory is in good accordance with experimental data.
Characterization of Surface Chromia Species on CrOx/TiO2 Catalysts
Authors: Wilson P. , Viswanath R.P.
Published: July 2017

Titania supported chromia catalysts have been employed for selective catalytic reduction (SCR) process because of their higher activity and selectivity. The catalytic activity of the titania supported chromia system is owing to the stabilization of the anchored chromia species having multiple chemical and molecular states on the surface. In the present work an attempt has been made to prepare titania supported chromia catalysts, from TiCl4 and CrO3 as precursors for the support and active phase respectively. Characterization of the catalysts have been made using FTIR spectroscopy and thermo analytical techniques such as thermogravimetric analysis (TGA), evolved gas analysis (EGA) and temperature programmed reduction (TPR). The EGA, TGA and FTIR results indicate that the surface hydroxyl groups of TiO2 (gel) has an influence on the chemical state of the chromium. Due to the surface anchoring, Cr+5 species have been detected on the surface of the fresh catalyst which decomposes to lower valence state on calcination. EGA results indicate that Cr+3 species having higher degree of coordinatively unsaturated centers is stabilized by gel titania as support. EG analysis and FTIR studies illustrate the coverage of the surface with similar type of sites at 10 wt.% chromia loading. TPR studies demonstrate the presence different kinds of surface chromia species with respect to chromia content.

Published: July 2017

The effect of complex formation of polyacids (polyacrylic (PAAc) and polymethacrylic (PMAAc)) with polyacrylamide (PAA) on their surface properties at solution/air interface has been studied by surface tension, electric conductivity and potentiometric measurements at 293±0.2 K. The relaxation time and surface activity of polycomplexes were calculated from kinetic data on the surface tension. It was found that during complex formation the relaxation time of a surface layer has a maximum and the surface activity of macromolecules is increased. Also the standard free energy of adsorption for PAA and polyacid-PAA polycomplexes were calculated. They are equal DadsG°293 = - 19.1±0.1 kJ/base-mol. for PAA, DadsG°293 = -21.2±0.1 kJ/basemol. for PMAAc-PAA polycomplex and DadsG°293 = -23.0±0.1 kJ/base-mol. for PAAc-PAA polycomplex (calculation per base-mole of PAA monomer link). It is shown that the surface activity and ability to decrease of the water surface tension is less for PMAAc-PAA than for PAAc-PAA. Such anomalous behaviour of PMAAc-PAA polycomplex probably is caused by an excessive strengthening of inner- and intermolecular hydrophobic interactions in macromolecules of PMAAc- PAA polycomplexes due to the presence of α-methyl groups in PMAAc macromolecules. Because of the rebuilding of macromolecule segments of complex by polarity at the interface is becoming a difficult one.

Published: July 2017

A wide range of rare polycyclic hydrocarbons can be obtained through catalytic processes involving norbornadiene (NBD). The problem of selectivity is crucial for such reactions. The feasibility of controlling
selectivity and reaction rate has been shown for cyclic dimerization, co-dimerization, isomerization and allylation of NBD. Kinetic rules have been scrutinized. Consistent mechanisms have been proposed. Factors
affecting directions of the reactions and allowing us to obtain individual stereoisomers quantitatively, have been established. A series of novel unsaturated compounds has been synthesized; they incorporate a
set of double bonds with different reactivity and can find an extremely wide range of applications.

The Impact Of PD-LGD Correlation On Expected Loss And Economic Capital
Authors: Van Vuuren Gary , De Jongh Riaan , Verster Tanja
Published: July 2017

The Basel regulatory credit risk rules for expected losses require banks use downturn loss given default (LGD) estimates because the correlation between the probability of default (PD) and LGD is not captured, even though this has been repeatedly demonstrated by empirical research. A model is examined which captures this correlation using empirically-observed default frequencies and simulated LGD and default data of a loan portfolio. The model is tested under various conditions dictated by input parameters. Having established an estimate of the impact on expected losses, it is speculated that the model be calibrated using banks' own loss data to compensate for the omission of correlation dependence. Because the model relies on observed default frequencies, it could be used to adapt in real time, forcing provisions to be dynamically allocated.
An Empirical Validation Of The Primary And Moderating Effects Of Income And Capital On Familiarity And Participation Of Limited Resource Farm Producers (LRFPs) In USDA Agricultural Programs
Authors: Omotoye Richard O. , Chinta Ravi , Mummalaneni Venkatapparao , Perry-Rivers Patrice Y.
Published: July 2017

We present empirical findings on the problem of low participation rate of Limited Resource Farm Producers (LRFPs)[1] in USDA programs. Our analysis is based on survey data directly sourced from LRFP population spread across twenty counties in Southern Virginia. The findings revealed that familiarity with and participation in USDA programs varied by type of farmers. While familiarity was moderate, participation was low. These main effects were moderated by access to capital. Our results broadly agree with findings from similar studies done on the subject in the past with an additional empirical insight that access to capital can enhance participation in USDA programs. We conclude the study with several practical ways for improving LRFP participation in USDA agricultural programs[i] According to the USDA, a Limited Resource Farmer or Rancher or Forest Owner is a person/applicant with direct or indirect gross farm sales not more than $173,600 (for FY2016) in each of the previous two years AND a person with a total household income at or below the national poverty level for a family of four or less than 50 percent of county median household income in each of the previous two years. An entity or joint operation can be an LRFP if all individual members independently qualify. http://lrftool.sc.egov.usda.gov/LRP_Definition.aspx http://www.nrcs.usda.gov/wps/portal/nrcs/main/national/people/outreach/slbfr/
Initial screening of vegetable amaranth landraces towards extending the vegetable list
Authors: Das Saubhik
Published: July 2017

Vegetable amaranth is considered as one of the most favorite vegetables in the world, especially in the hot and humid tropical regions of the globe. Two of them are most popular i.e., Amaranthus tricolor and Amaranthus blitum, both are represented by a large number of morphotypes or landraces or varieties, which are taxonomically ill-defined, many of them are consumed as palatable vegetables as they look like the conventional cultivars. Due to wide morphological diversity and presence of many synonyms both the species are supposed to represent two species complex or aggregates viz., “Tricolor complex” and “Blitum complex”. Two new species have been identified from their landraces. In the present investigation morphometric analysis along with biochemical and molecular methodologies were applied to explore the relative closeness among few well known, popular vegetables and few less known landraces for better utilization of the crop biodiversity of vegetable amaranths. The experimental data were statistically analyzed and separate Dendrograms were computed on three parameters (Morphology, Isozyme polymorphism and ISSR band profile).The members of “Tricolor complex” were clustered together in a single group along with two newly introduced species A. bengalense (a member of “Blitum complex”) and A. parganensis (a gynomonoecious member of “Tricolor complex”). Tricolor complex represents a plexus of species with varying sexual behavior from gynomonoecy to monoecy and indicates probable origin of monoecious  Amaranthus tricolor varieties or landraces from gynomonecious member like A. parganensis as recent introduction. The study indicated a close alliance between A. bengalense, A. parganensis, A. tricolor landrace and popular A. tricolor varieties which consolidated the feasibility of utilizing the landrace and newly introduced species as potential vegetable.
Adventitious root formation in branch cuttings of Taxus wallichiana Zucc.(Himalayan yew): A clonal approach to conserve the scarce resource
Authors: Aslam Mohd , Raina Parvaiz A. , Rafiq Rouf Ur , Siddiqi T.O. , Reshi Zafar A.
Published: July 2017

Himalayan yew (Taxus wallichiana Zucc.), is an economically valuable plant and critically endangered due to overexploitation for the isolation of Taxol,an exciting anticancer drug from its bark and leaves. Since the species is unisexual and due to its long seed dormancy period and rapid loss of viability coupled with low survival percentage, its natural regeneration from seeds is very poor. As the seed raised plants add little growth, propagation by stem cuttings was tried under natural conditions and a considerable success was achieved after making use of different auxins (Indole-3- Acetic Acid-IAA, Indole Butyric Acid-IBA and Naphthalene Acetic Acid-NAA) in different concentrations. A Randomized block design (RBD) was adopted for laying the experiment of the present study. Of the ten treatments studied, IBA at 500ppm performed best of all the treatments and registered higher callusing percentage, rooting percentage, number of roots and length of roots in the juvenile shoot cuttings of the species. The results achieved through the application ofplant growth regulators (PGRs)by way of adventitious root formation (ARF) could be useful for the management of this understory coniferous tree species, whether for conservation, habitat restoration or for the production of Taxol,a promising anti-cancer agent. The technique evolved will be the most handy, quickest, inexpensive and can be applied any where in its natural habitat for the restoration and restocking of this valuable plant, which is otherwise facing the peril of extinction throughout the range of its distribution including Indian Himalayas.
A systematic review of the literature in Europe relating to clinical legal education
Authors: Dunn Rachel
Published: July 2017

As my PhD research is European focused, looking at knowledge, skills and attributes development in live client clinics, I wanted to find all the European literature relating to clinical legal education. The aim of this research was to find all of the European literature surrounding clinical legal education available to me, to explore the kind of research published and to identify any gaps in knowledge. With an explosion of literature within the field, and more research undertaken every year, finding the literature which related to my research was challenging. To help aid this work I embarked on a systematic review, building on work by Tribe Mkwebu,<a title="" href="file:///S:/Academic%20Library%20Services/Research%20Support%20Team/Scholarly%20Publications/OJS/International%20Journal%20of%20Clinical%20Legal%20Education/24-2%20files/4.%20dunn%20lit%20review.docx#_ftn1">[1] systematically searching for peer reviewed articles. This research was initially presented at the European Network of Clinical Legal Education’s Spring Workshop, 2015, Northumbria University.  This article highlights the journey through this literature. Firstly, it explains what a systematic review is and how it can be used within mixed methods research. It then goes on to outline the methodology used and the number of articles sourced, excluded and synthesised. The analysis shows the amount of papers published before 2015 and their basic content. Finally, I discuss my reflection on the systematic review, what I thought went well and what didn’t, explaining how it was received at the Workshop.
Rastreio da Diabetes em Doentes com Doença Macrovascular Coronária: As Novas Guidelines Europeias são um Retrocesso?
Authors: Ribeiro Andreia , Baptista Sérgio Bravo , Faustino Mariana , Alves Paulo , E Abreu Pedro Farto , Gil Victor Machado , Morais Carlos
Published: July 2017

Introdução: As novas recomendações europeias de diabetes mellitus tipo 2 e doença cardiovascular sugerem que o risco de diabetes mellitus tipo 2 deve ser avaliado através do score de risco FINnish Diabetes RIsk SCore e que o rastreio de diabetes mellitus tipo 2 na população com doença arterial coronária deve ser efetuado apenas com a glicemia plasmática em jejum e a HbA1, remetendo a prova de tolerância oral à glicose para os casos ‘inconclusivos’. Pretendemos avaliar os resultados desta estratégia, que difere da previamente defendida nas guidelines.Material e Métodos: A glicemia plasmática em jejum, HbA1c e a prova de tolerância oral à glicose (75 g, 2 horas) foram avaliadas prospectivamente num grupo de doentes consecutivos submetidos a intervenção coronária percutânea, sendo usada a classificação da ADA para pré-diabetes mellitus tipo 2 e diabetes mellitus tipo 2. O risco de diabetes foi avaliado de acordo com o FINnish Diabetes RIsk SCore.Resultados: Foram incluídos 135 doentes (idade média 62,3 +/- 13,1 anos; 99 homens). Usando a prova de tolerância oral à glicose e a HbA1c, foram diagnosticados 18 (13,3%) novos casos de diabetes mellitus tipo 2 e 77 (57,0%) casos de pré-diabetes mellitus tipo 2. A glicemia plasmática em jejum + HbA1c identificou 12/18 doentes com diabetes mellitus tipo 2 (Sens 66,7%; valor preditivo negativo 95,1%; Kappa 0,78; p < 0,0001) e 83 do total (pré-diabetes mellitus tipo 2/ diabetes mellitus tipo 2) de 95 doentes com distúrbios da glucose (Sens 87,4%; valor preditivo negativo 76,9%). Realizar adicionalmente prova de tolerância oral à glicose nos 29 doentes com um FINnish Diabetes RIsk SCore elevado permitiu diagnosticar 15/18 doentes com diabetes mellitus (Sens 83,3%; valor preditivo negativo 97,5%; Kappa 0,85; p < 0,0001) e 86/95 dos doentes com distúrbios da glucose (Sens 90,5%; valor preditivo negativo 81,6%).Discussão: Apesar da melhoria diagnóstica, um em cada seis doentes com diabetes mellitus tipo 2 não seria diagnosticado por esta estratégia.Conclusão: A utilização do FINnish Diabetes RIsk SCore como forma de selecionar os doentes candidatos a rastreio com prova de tolerância oral à glicose melhora a capacidade diagnóstica, quando comparada com a simples avaliação da glicemia plasmática em jejum e da HbA1c. No entanto, um em cada seis doentes com diabetes mellitus tipo 2 não é identificado com esta metodologia.

Published: July 2017

Introduction: Anti-vascular endothelial growth factor therapy has revolutionized the treatment of wet age-related macular degeneration; however, it is important to monitor actual use of ranibizumab and related treatment outcomes in routine practice.Material and Methods: This was a retrospective, observational study to monitor the 2-year outcomes following ranibizumab treatment for wet age-related macular degeneration in Portugal. Patients treated between January 2009 and December 2009 were retrospectively evaluated. All decisions were made by the treating physician in accordance with their usual routine clinical practice. The primary assessment was mean change in visual acuity score using Early Treatment Diabetic Retinopathy Study or Snellen equivalent.Results: A total of 128 patients with wet age-related macular degeneration were analyzed (mean age 79.4 years; mean visual acuity score 54.2 letters). Mean change in visual acuity score from baseline was –1.6 letters (n = 82) at year one and –5.1 letters (n = 72) at year two. The mean number of ranibizumab injections was 3.8 (year one) and 1.6 (year two). On average, patients attended 8.6 and 5.0 visits and optical coherence tomography was used in 75.0% of patients in year one and in 56.3% of patients in year two, respectively.Discussion: Despite a relatively high number of visits, including monitoring visits and use of optical coherence tomography - guided therapy, few injections were administered and visual acuity was not improved.Conclusion: These findings indicate that as-needed treatment resulted in under-dosing in a real-life setting in Portugal. Such limitations may also be related to increasing numbers of patients, resulting in clinic saturation.

Authors: Dawood Eethar Thanon , Ghanim Tamara Waleed
Published: July 2017

The present work deals with engineering properties of high performance mortar (HPM) to be used as a repair material. The experimental study was conducted on HPM reinforced with mono steel fibers and hybrid fibers consist of steel and polypropylene fibers. The economical efficiency of the designed mono and hybrid fibers reinforced mortar were presented. The results indicate that the hybridization of 1.8% steel fibers and 0.2% polypropylene fibers is very beneficial to decrease the production cost of fiber reinforced mortar for large scale construction project applications. The combined system of substrate concrete with different mixes of HPM was used to study its bond strength properties. The experimental tests are: two-part bond strength tests in additional to three part-bond strength tests. It was found that HPM reinforced by hybrid fibers has the best performance when two-part bond strength is required. On the other hand, in three parts bonding, the combined system of NC with epoxy has the best bond strength while HPM reinforced fibers show a better failure mode.

Published: July 2017

Esta pesquisa discute, numa aproximação com as narrativas de Alice no País das Maravilhas, da Mitologia Grega de Narciso e dos Meninos Perdidos na Terra do Nunca, os modos de articulação das experiências corpóreas dos sujeitos juvenis pela produção e publicização fotográfica nas redes sociais, sinalizando outras rotas de aprendizagens – num olhar específico para as narrativas tecidas na rede social Facebook. O objetivo foi investigar e analisar as narrativas fotográficas juvenis compartilhadas nas redes sociais digitais, de modo a compreender outras rotas de aprendizagens sinalizadas por essas narrativas. É uma pesquisa qualitativa, de cunho descritivo e analítico, fundada na Netnopesquisa. A pesquisa concluiu que os corpos juvenis representados nas fotografias publicadas no Facebook são canais tecno-digitais de comunicação; os sujeitos juvenis imprimem em seus corpos publicizados nas redes sociais a avatarização da liberdade; os corpos juvenis perfilados no Facebook se educam pelos sentidos e se articulam numa trajetória única de cada sujeito; o Facebook é instância formativa e as narrativas fotográficas emprestam liberdade para a não fixação de seus corpos.
AS TECNOLOGIAS DE INFORMAÇÃO E COMUNICAÇÃO COMO AGENTES DE INTEGRAÇÃO DO CURRÍCULO COM A GLOCALIDADE
Authors: Silva Bento Duarte , Sartori Ademilde Silveira , Martini Rafael Gué
Published: July 2017

A partir de um estudo de caso qualitativo sobre o programa de extensão Educom.Cine, que promoveu a produção audiovisual no ensino fundamental, refletimos sobre a possibilidade das Tecnologias de Informação e Comunicação (TIC) se configurarem como a espinha dorsal de um currículo mais atento aos processos de integração da escola com sua localidade. Nesta perspectiva, a escola se tornaria o centro de gerenciamento de diversos canais comunitários de comunicação, onde a produção escolar seria vinculada e publicizada à toda a comunidade. Esta se configuraria em uma proposta de integrar o uso das TIC no ambiente escolar com seu uso não-formal, estimulando os estudantes a agir no local (bairro) pensando também no global, numa perspectiva glocal.

Este artigo apresenta a aplicação da metodologia do Planejamento Estratégico Situacional (PES) na Pró Reitoria de Avaliação e Planejamento (PROAP), e os primeiros resultados deste processo.  Entende-se que é necessário ressaltar que este planejamento deve ser dinâmico, e de um modo geral adaptar-se a dinâmica do ambiente interno e externo, e de modo especial à dinâmica das pessoas. Por este motivo tão importante quanto a realização do planejamento é seu monitoramento a fim de promover ajustes que aumentem a capacidade de realizar sua visão de futuro.
Administração Pública Brasileira no Século XXI - Caminhamos para Alguma Reforma?
Authors: Pinto Juliana De Fátima , Dos Santos Leonardo Tadeus
Published: July 2017

Este trabalho faz uma reflexão sobre a influência das reformas já realizadas no Brasil nos governos Luiz Inácio Lula da Silva e Dilma Vana Rouseff. O objetivo do artigo é, portanto, analisar como as reformas ocorridas no país ao longo do século XX estão inseridas em ambos os governos. Também buscou-se compreender qual foi a abertura do Estado em termos da construção de uma administração pública societal. O referencial teórico foi construído a partir da compreensão das três reformas vivenciadas no país: 1930, 1967 e 1995. Em seguida foram analisadas as notícias publicadas no site do Ministério do Planejamento, Orçamento e Gestão com o termo “reforma”. Utilizou-se a análise temática de Bardin (2007) para o tratamento dos dados. Observou-se avanços em termos da participação de atores sociais nas decisões da administração pública federal, mas essa não foi desenvolvida ao longo de todo o período do governo PT.

Published: July 2017

The internal corrosion of cast iron and steel pipes is one of the main issues that drinking water distribution operators are facing. This study evaluated the relevance of 10 known corrosion indices according to their estimate of corrosion rate and iron particle release for 20 different water qualities. Pilot-scale contact trials were run over 45 days using cast iron and steel coupons. Corrosion rate was measured by coupon weight-loss and by an online linear polarization rate probe. Particle release was monitored by an online turbidimeter. The results showed that none of the indices properly predicted the level of risk associated with each water and that corrosion and particle release were not correlated. Two novel indices were developed to predict the corrosion and particle release risks independently of each other. The corrosion index showed a strong linear correlation with the corrosion rate of cast iron and slightly less reliable results for steel. The Particle Emission Index presented good correlation with turbidity in waters following contact with cast iron. These two indices thus showed interesting potential as tools to limit internal corrosion risks for metal pipes in water distribution networks.
Chinese Administrative Reforms: A Replica or Derivative of the Western NPM Model?
Authors: Zhang Mengzhong , Holzer Marc
Published: July 2017

At the theoretical level in the public administration community, there is an ongoing debate as to whether public administration principles can be universally applied to any country or whether they are bounded by political, economic, social, cultural, historical, environmental and traditional factors. While there is an increasing observation in the 21st century that convergence of administrative reforms between developing and developed countries has great momentum, this paper argues that national context plays a significant (if not vital) role in a specific country's administrative reforms. To put this argument in context, the paper examines similar and dissimilar features of Chinese administrative reforms with that of USA, with a conclusion that Chinese administrative reform is not a replica, but rather a derivative, of the Western NPM Model.

Published: July 2017

Cancer has become the second leading cause of death worldwide. The incidences of cancer are rising at an alarming rate but it can be reduced and controlled by evidence-based strategies for cancer prevention, early detection, and management of patients with cancer. Historically, it is proven that plants and their metabolites have great potential in the treatment of various acute diseases as well as chronic disorders. The novel bioactive compounds from many plants are being studied as potential therapeutic agents because of their high activity and low toxicity. This review gives a comprehensive description of such medicinal plants which have been studied as potentially effective against cancer.
SEARCHING ANTIVIRAL DRUGS FOR EBOLA VIRUS FROM PHYTO-CONSTITUENTS OF AZADIRACHTA INDICA: APPLICATION OF MOLECULAR MODELING STUDIES
Authors: Parasuraman P , R Suresh , P Perumal
Published: July 2017

ABSTRACTThe current objective of the study is to identify some naturally occurring product from Azadirachta indica and evaluate its binding activity against VP24 protein as Ebola virus target through in silico docking studies. Reported phytoconstituents of Azadirachta indica were prepared for docking evaluation using Brincidofovir as the standard. In silico docking studies were carried out using GLIDE (Grid-based Ligand Docking with Energetics) is a ligand binding program provided by Schrödinger. These results showed that all the selected phytoconstituents showed binding energy ranging between -7.95 kcal/mol to -1.54 kcal/mol when compared with that of the standard (-6.06 kcal/mol). Naturally occurring products Catechin, Epicatechin, Gallic acid and Nimbolide are potential than the standard brincidofovir but Azadirachtin, Margolonone, Mahmoodin, Isomargolonone, Gedunin, Margolone, Nimbidin and Nimbin have low binding affinity towards target when compared with the standard. These molecular docking analyses of phytoconstituents of Azadirachta indica could lead to the further development to identify the potent drugs for the treatment of Ebola virus. KEYWORDS: Azadirachta indica, VP42 protein, Ebola virus, in silico docking.

Abstract :Introduction: From the era of absolute contraindication to the phase of preferred treatment, the technique of laparoscopic cholecystectomy advances with time. Here, we report our experience of laparoscopic cholecystectomy in 20 patients of liver cirrhosis. In our institute, laparoscopic cholecystectomy is the preferred choice for cholelithiasis in cirrhotic patient.Methods: In last 2 years, 180 laparoscopic cholecystectomies were performed and 20 patients were cirrhotic. Their data analyzed retrospectively in terms of preoperative optimization, operative technique and results.Results: Laparoscopic cholecystectomy was completed successfully in 19 patients and one was converted to open. Mean operative time was 54 minutes. No additional port was required in all cases. Calot’s first dissection was performed in 18 patients and fundus first technique was used in 2 patients due to unclear anatomy. Liver bed bleeding was present in 16 patients, which was controlled effectively. Subhepatic drain was placed in 12 patients. There was no mortality. Morbidity  in two patients was worsening of ascites in one; and incisional hernia in other patient which was converted to open. Port site complications were not noted in any patient and there was no evidence of intraabdominal bleeding or bile leak postoperatively. Blood and component transfusion was required in 2 patients. Average length of hospital stay was 4.8 days.Conclusion: Though laparoscopic cholecystectomy may be difficult in cirrhotic patients but it is feasible and relatively safe. It offers many advantages in cirrhotic patients and associated with low morbidity when compared with open surgery.Keywords: cirrhosis, laparoscopic cholecystectomy, difficult cholecystectomy

Objective: Aim of the study was to evaluate the prevalence and significance of inferior turbinate hypertrophy (ITH) in adult indo-dravidian patients with deviated nasal septum (DNS). Methods: Analysis of sinonasal computerized tomography (CT) images of 86 patients having DNS was done during October 2015-December 2016 for evaluation of severity of the associated ITH. Values of maximum width of medial mucosa, bone and total width of the turbinate were measured. Patients with inflammatory or expansile sinonasal masses were excluded. Results: Total 86 patients with varying degrees of septal deviation with ages ranging from 18 to 72 years (mean age of 42.8 years) were distributed as: Group I, mild cases and Group II, moderate and severe DNS cases. Patients having ITH on the contralateral side of deviation were included in the study group. The dimensions of the ITH were evaluated. The medial mucosal component of the ITH underwent maximum hypertrophy as compared to bone and lateral mucosa components. The average medial mucosa, bone and total turbinate widths of the inferior nasal concha as well as lateral offset in Group II DNS cases were 5.21 mm, 1.76 mm, 9.96 mm and 8.74 mm, respectively. Total width and width of medial mucosa of ITH in relation to the severity of septal deviation was statistically significant (p=0.0001 and 0.0098). Conclusion: Present study evaluated the relationship between DNS and compensatory ITH. The findings support the decision to excise the inferior turbinate at the time of septoplasty, because of the significant mucosal expansion.

Objectives: To study in vitro cytotoxic activity of total alkaloid extracts of Pinus sabiniana L., Phoenix dactylifera L. and Ferocactus sp. L. against breast cancer cell line Michigan Cancer Foundation-7 (MCF-7) and non-tumorigenic fetal hepatic cell line (WRL-68). Methods: Plant powder of each P. sabiniana L. leaves, P. dactylifera L. pollen grains, and Ferocactus sp. L. The leaves were extracted separately with 80% methanol, chloroform at pH 2 and pH 10 and the chloroform portion was dried to obtain the total alkaloid extracts. The total alkaloids were detected qualitatively by Mayer’s, Dragendorff’s and Hager’s reagents and estimated quantitatively by bromocresol green spectrophotometry depending on the atropine calibration curve. The cytotoxic activity was evaluated by 3-[4, 5-dimethylthiazoyl]-2, 5-diphenyltetrazolium bromide assay. Results: The extract of P. sabiniana L. had highest total alkaloid content (164.62±2.8 mg/100 g dry weight of plant) than the other plants (P. dactylifera l., Ferocactus sp. L.), the total alkaloids of Ferocactus sp. L. and P. dactylifera L., reduced the cell viability of both cell lines, the highest reduction occurred in the concentration 400 μg/ml was 46±2.20% (MCF-7) and 56.2±2.2% (WRL-68) for Ferocactus sp. L., followed by 56.2±2.2% (MCF-7) and 57.5±3.2% (WRL-68) for P. dactylifera L. The alkaloids of P. sabiniana was very lower effects on both cell lines MCF-7, and WRL-68 was 89.3±3.44% and 90.16±2.7%, respectively, at the same concentration. Conclusion: Plant alkaloids had variable effects against cancer and normal cell lines depending on the type of alkaloid compounds and their concentration in the extract.
