Biochemical Mechanism of Rhododendrol Induced Leukoderma
Venue: International journal of molecular sciences
Year: 2018

RS 4 (4 hydroxyphenyl) 2 butanol (rhododendrol (RD) a skin whitening ingredient was reported to induce leukoderma in some consumers. We have examined the biochemical basis of the RD induced leukoderma by elucidating the metabolic fate of RD in the course of tyrosinase catalyzed oxidation. We found that the oxidation of racemic RD by mushroom tyrosinase rapidly produces RD quinone, which gives rise to secondary quinone products. Subsequently, we confirmed that human tyrosinase is able to oxidize both enantiomers of RD. We then showed that B16 cells exposed to RD produce high levels of RD pheomelanin and protein SH adducts of RD quinone. Our recent studies showed that RD eumelanin an oxidation product of RD exhibits a potent pro oxidant activity that is enhanced by ultraviolet A radiation. In this review, we summarize our biochemical findings on the tyrosinase dependent metabolism of RD and related studies by other research groups. The results suggest two major mechanisms of cytotoxicity to melanocytes. One is the cytotoxicity of RD quinone through binding with sulfhydryl proteins that leads to the inactivation of sulfhydryl enzymes and protein denaturation that leads to endoplasmic reticulum stress. The other mechanism is the pro oxidant activity of RD derived melanins that leads to oxidative stress resulting from the depletion of antioxidants and the generation of reactive oxygen radicals.
Working Paper 05 11 Productivity gains and spillovers from offshoring
Year: 2011

Offshoring is generally believed to be productivity enhancing and this belief is underpinned by economic theory. This article contributes to the growing literature that tests empirically whether offshoring does indeed help to improve productivity. Estimating the impact of materials and business services offshoring on productivity growth with industry level data for Belgium over the period 1995 2004, we investigate this issue separately for manufacturing and market services. The results show that there is no productivity effect of materials offshoring, while business services offshoring leads to productivity gains especially in manufacturing. In addition, we look at the possibility of rent spillovers from offshoring. Productivity gains from offshoring in one industry may feed through to other industries that purchase its output for intermediate use if, due to offshoring, the user value exceeds the price of the output. The lack of evidence of such rent spillovers from either materials or business services offshoring in the data leads us to conclude that firms manage to internalise all efficiency gains from offshoring.
A STUDY TO ASSESS THE EFFECTIVENESS OF LAMAZE BREATHING EXERCISE ON LABOUR PAIN AMONG PRIMI GRAVID WOMEN ADMITTED IN LABOUR WARD AT MGMC
Year: 2017

Reproduction is a basic function of human beings. Pregnancy and delivery are natural, joyous, human events. Childbirth is a universally celebrating event and happiest occasion in a women's life. Pregnant women commonly worry about the pain they will experience during Labour and childbirth. Labour pain is one of the severest pain. Controlling labour pain is a major concern of maternity care. Nowadays, interest in non pharmacological methods may be helpful for their Labour experience and also no side effects. Lamaze breathing exercise is one of breathing exercise it helps to manage the pain during Labour and delivery.  The aim of the present study was to evaluate the effectiveness of lamaze breathing exercise on labour pain among primi gravid women in labour ward at MGMC RI, Puducherry.  The research design adopted for the study was experimental design (Times Series& Reinstituted Design) The study was conducted at labour ward, Mahatma Gandhi Medical college and hospital, Puducherry. Simple random sampling technique (Lottery method) was used to select the samples. Sixty samples were selected for the study (30 samples each in Experimental and Control group) After obtaining the signature in the consent form, data were collected to assess the demographic variables and a Pre test was carried out to assess the level of pain during labour using Visual Analogue Scale in both the groups. In Experimental group Lamaze breathing exercise was administered and Control group there was no intervention. As the primi gravid women progress with labour the lamaze breathing exercise reinstituted with Pre test and Post test.  The study result shows that in experimental group Pre test 1 mean value 4.67 Post test 1 mean value 4.07 and control group Pre test 1 mean value 5.10, Post test 1 mean value 7.23.In comparing Pre test 2 and post test 2 in both groups. In Pre test2 mean value 5.90, Post test2 mean value 4.47 and Control group Pre test 2 mean value 8.87 and post test 2 mean value 9.33. In experimental group at 'P' value 0.9341 and control group at 'P' value 0.0000. Comparison between Pre test2 and Post test 2 of both groups. In experimental group at 'P' value 0.0000 and control group at 'P' value 0.0015 .This study reveals that there was a significant reduction in level of pain during labour by using lamaze breathing exercise at p value <0.001  This study reveals that post test level of pain score was lower than the pre test score after administration of lamaze breathing exercise. Thus this study proves that lamaze breathing exercise was highly statistically significant in reduction of pain during labour among primi gravid women.
Bioenergetics and growth in the ctenophore Pleurobrachia pileus
Venue: Hydrobiologia
Year: 2010

Knowledge of how energetic parameters relate to fluctuating factors in the natural habitat is necessary when evaluating the role of gelatinous zooplankton in the carbon flow of coastal waters. In laboratory experiments, we assessed feeding, respiration and growth of the ctenophore, Pleurobrachia pileus, and constructed carbon budgets. Clearance rates (F, l d 1) of laboratory reared Acartia tonsa as prey increased as a function of ctenophore polar length (L, mm) as F 0.17L1.9. For ctenophores larger than about 11 mm, clearance rate was depressed in containers of 30 50 l volume. Clearance rates on field collected prey were highest on the copepod, Centropages typicus, intermediate on the cladoceran, Evadnenordmanni and low on the copepods, Acartia clausi and Temora longicornis. Specific growth rates of 8 10 mm P. pileus increased with increasing prey concentrations to a maximum of 0.09 d 1 attained at prey carbon densities of 40 and 100 mg C l 1 of Artemia salina and A. tonsa, respectively. Weight specific respiration rates increased hyperbolically with prey concentration. From experiments in which growth, ingestion and respiration were measured simultaneously, a carbon budget was constructed for individuals growing at maximum rates; from the measured parameters, the assimilation efficiency and net growth efficiency were estimated to be 22 and 37% respectively. We conclude that the predation rates of P. pileus depend on ctenophore size, prey species, prey density and experimental container volume. Because the specific growth rates, respiration, assimilation and net growth efficiencies all were affected by food availability, knowledge of the ambient prey field is critical when evaluating the role of P.pileus in the carbon flow in coastal waters.
Utility Rate Equations of Group Population Dynamics in Biological and Social Systems
Venue: PloS one
Year: 2013

We present a novel system of equations to describe the evolution of self organized structured societies (biological or human) composed of several trait groups. The suggested approach is based on the combination of ideas employed in the theory of biological populations, system theory, and utility theory. The evolution equations are defined as utility rate equations, whose parameters are characterized by the utility of each group with respect to the society as a whole and by the mutual utilities of groups with respect to each other. We analyze in detail the cases of two groups (cooperators and defectors) and of three groups (cooperators, defectors, and regulators) and find that, in a self organized society, neither defectors nor regulators can overpass the maximal fractions of about each. This is in agreement with the data for bee and ant colonies. The classification of societies by their distance from equilibrium is proposed. We apply the formalism to rank the countries according to the introduced metric quantifying their relative stability, which depends on the cost of defectors and regulators as well as their respective population fractions. We find a remarkable concordance with more standard economic ranking based, for instance, on GDP per capita.
Functionalization of PET Track Etched Membranes by UV Induced Graft (co)Polymerization for Detection of Heavy Metal Ions in Water
Venue: Polymers
Year: 2019

Nowadays, water quality monitoring is an essential task since environmental contamination and human exposure to heavy metals increased. Sensors that are able to detect ever lower concentrations of heavy metal ions with greater accuracy and speed are needed to effectively monitor water quality and prevent poisoning. This article shows studies of the modification of flexible track etched membranes as the basis for the sensor with various polymers and their influence on the accuracy of detection of copper, cadmium, and lead ions in water. We report the UV induced graft (co)polymerization of acrylic acid (AA) and 4 vinylpyridine (4 VPy) on poly(ethylene terephthalate) track etched membrane (PET TeMs) and use them after platinum layer sputtering in square wave anodic stripping voltammetry (SW ASV) for detection of Cu2+ Cd2+ and Pb2+ Optimal conditions leading to functionalization of the surface and retention of the pore structure were found. Modified membranes were characterized by SEM, FTIR, X ray photoelectron spectroscopy (XPS) and colorimetric analysis. The dependence of the modification method on the sensitivity of the sensor was shown. Membrane modified with polyacrylic acid (PET TeMs g PAA) poly(4 vinylpyridine) (PET TeMs g P4VPy) and their copolymer (PET TeMs g P4VPy/PAA) with average grafting yield of 3% have been found to be sensitive to ug/L concentration of copper, lead, and cadmium ions. Limits of detection (LOD) for sensors based on PET TeMs g PAA are 2.22, 1.05, and 2.53 ug/L for Cu2+ Pb2+ and Cd2+ respectively. LODs for sensors based on PET TeMs g P4VPy are 5.23 ug/L (Cu2+ 1.78 ug/L (Pb2+ and 3.64 ug/L (Cd2+ ug/L. PET TeMs g P4VPy/PAA electrodes are found to be sensitive with LODs of 0.74 ug/L(Cu2+ 1.13 ug/L (Pb2+ and 2.07 ug/L(Cd2+ Thus, it was shown that the modification of membranes by copolymers with carboxylic and amino groups leads to more accurate detection of heavy metal ions, associated with the formation of more stable complexes.
MnOx decorated VOx/CeO2 catalysts with preferentially exposed {110} facets for selective catalytic reduction of NOx by NH3
Year: 2020

Highly dispersed MnOx decorated VOx/CeO2 catalysts with preferentially exposed {110} facets were chosen to improve the low temperature (200 250 degC) NH3 SCR activity. In this work, the catalytic data on NH3 SCR performance indicated that the improved catalytic activity were achieved when both VOx and MnOx were presented on the {110} facet of CeO2 nanorods. It could be deduced that the highly dispersed surface monomeric vanadium species were the reason for the high NH3 SCR activity from 51V Nuclear Magnetic Resonance (NMR) Raman, X ray diffraction (XRD) and Transmission electron microscopy (TEM) It was also suggested that CeO2{110} facet and surface oxygen vacancy defects had significant effects on the promotion of NH3 SCR performance. Furthermore, the redox cycle of V5+/V4+ and the quantities of NH3(L) species and bridging nitrate species were increased by the introduction of Mn. The Langmuir Hinshelwood mechanism is possible because abundant surface NH3(L) NH4+(B) and bridging nitrate species were produced as intermediates studied via in situ DRIFTs.
A Hybrid MCDM Approach for Large Group Green Supplier Selection With Uncertain Linguistic Information
Venue: IEEE Access
Year: 2018

With increasing global concerns toward environmental protection and sustainable development, green supply chain management (GSCM) has drawn much attention from academicians and practitioners. Selecting an optimal green supplier is a critical part of GSCM, which can be viewed as a kind of multi criteria decision making (MCDM) problem. To derive the best result, a large group of decision makers are often involved in the green supplier selection nowadays. Besides, decision makers tend to express their evaluations utilizing uncertain linguistic terms due to the vagueness of human thinking. Hence, this paper aims to propose a hybrid MCDM approach for green supplier selection within the large group setting. More concretely, interval valued intuitionistic uncertain linguistic sets are applied for assessing the performance of green suppliers concerning each criterion. Ant colony algorithm is utilized to cluster decision makers into several subgroups. The linear programming technique for multidimensional analysis of preference is adopted for the determination of the optimal weights of criteria objectively. Finally, an extended MULTIMOORA approach is utilized to generate the ranking of alternative suppliers. The practicality and usefulness of the developed large group green supplier selection framework is illustrated using an empirical example of a real estate company.
Network connected UAV communications
Year: 2018

The articles in this special section focus on network connected unmanned aerial vehicles (UAV) communications. Unmanned aerial vehicles (UAVs) have found fast growing applications in recent years, such as for cargo delivery, precision agriculture, aerial monitoring, video streaming, traffic control, rescue and search, and communication relaying. As the number of UAVs and their related applications grow explosively in the coming years, it is imperative to develop high performance wireless communication technologies, not only for supporting the ultra reliable UAV remote command and control (C&C) to ensure their safe operations, but also for enabling high capacity mission related information transmission for rate demanding applications. Integrating UAVs into cellular and satellite networks is a promising solution to achieve the above goals, where UAVs with their own missions could be connected with either cellular base stations (BSs) or satellites as special aerial users, referred to as network connected UAVs.
Climate change coverage in Indian print media a discourse analysis
Year: 2012

Climate change has attracted much political and media attention in recent years. While western media coverage of this issue has been well documented, there is a paucity of media analysis for climate change coverage in developing economies. This paper examines the media discourse generated in India among three leading English language dailies (with centrist and conservative news values) during globally prominent climate change events. A quantitative analysis shows a peak in coverage when the Fourth Assessment Report by the IPCC was released in February 2007, and when climate change crusaders won the Nobel Peace Prize in October 2007. A qualitative content analysis reveals that frames such as scientific certainty, energy challenge, social progress, public accountability and looming disaster are widely employed by the elite Indian press to raise relevant social, economic and political issues. Cross cultural comparisons of media constructs, especially with Europe and America, help identify the further development of risk communication in this field. In a broader, global sense, this work can be tied in to the idea of the 'climatic turn' as suggested by European researchers with climate change evolving into a grand, transnational narrative.
Transient Supersolid Properties in an Array of Dipolar Quantum Droplets
Venue: Physical Review X
Year: 2019

We study theoretically and experimentally the emergence of supersolid properties in a dipolar Bose Einstein condensate. The theory reveals a ground state phase diagram with three distinct regimes a regular Bose Einstein condensate, incoherent and coherent arrays of quantum droplets. In the latter the droplets are connected by a finite superfluid density, which leads in addition to the periodic density modulation to a robust phase coherence throughout the whole system. We further theoretically demonstrate that we are able to dynamically approach the ground state in our experiment and that its lifetime is only limited by three body losses. Experimentally we probe and confirm the signatures of the phase diagram by observing the in situ density modulation as well as the phase coherence using matter wave interference.
Caracterizacion del desarrollo del lenguaje escrito en preescolar en funcion de los medios de comunicacion.
Year: 2018

Como dice Levy, (2008) los ninos de las nuevas generaciones desarrollan el lenguaje escrito en el contexto digital de los medios de comunicacion. Sobre este panorama, Formby (2014) en 2013 en Reino Unido, el 28% de los ninos de tres a cuatro anos de edad utilizan una tableta, otros autores han estudiaron la relacion de las tabletas y las habilidades y conocimientos de lectura y escritura en los ninos preescolares (Neumann y Neumann, 2014; Nacher, Jaen, Navarro, Catala y Gonzalez, 2015) sin embargo en Mexico se desconoce la influencia del uso de tecnologias en el desarrollo del lenguaje escrito y en las actividades de lectura de los ninos, a pesar de que en el sistema educativo del sector publico no contempla las tecnologias, los ninos en casa ya interactuan con dichas tecnologia, por lo tanto, este estudio tuvo como objetivo caracterizar el lenguaje escrito que estan desarrollando los ninos de preescolar de educacion publica en funcion del uso de medios de comunicacion como tecnologias para actividades de lectura y escritura. Participaron 60 ninos de educacion preescolar previo consentimiento de los padres y la institucion educativa, se les evaluo el desarrollo de lenguaje escrito y conocimientos de lectura con la Bateria BEHLOyE (Guarneros, 2016) sus padres contestaron el Cuestionario Actividades en el Hogar con y sin Tecnologias. Los resultados permitieron caracterizar los conocimientos de la lectura y se obtuvieron las muestras de escritura de los ninos a partir de indicadores como direccionalidad, calidad del mensaje, organizacion linguisticas y finalmente el nivel de escritura de los ninos de preescolar segun su grado escolar y la preferencias de realizar actividades lectura y escritura en Smartphone, computadora o tableta y aplicaciones de lectura o escritura. Se concluye que estos aspectos permiten construir el perfil de alfabetizacion emergentes en contexto digital que tienen los ninos mexicanos de educacion publica.
Numerical solution of a coefficient inverse problem with multi frequency experimental raw data by a globally convergent algorithm
Venue: J. Comput. Phys.
Year: 2017

We analyze in this paper the performance of a newly developed globally convergent numerical method for a coefficient inverse problem for the case of multi frequency experimental backscatter data associated to a single incident wave. These data were collected using a microwave scattering facility at the University of North Carolina at Charlotte. The challenges for the inverse problem under the consideration are not only from its high nonlinearity and severe ill posedness but also from the facts that the amount of the measured data is minimal and that these raw data are contaminated by a significant amount of noise, due to a non ideal experimental setup. This setup is motivated by our target application in detecting and identifying explosives. We show in this paper how the raw data can be preprocessed and successfully inverted using our inversion method. More precisely, we are able to reconstruct the dielectric constants and the locations of the scattering objects with a good accuracy, without using any advanced a priori knowledge of their physical and geometrical properties.
Relationship between Difficulty in Emotion Regulation and Internet Addiction in College Students: A One Year Prospective Study
Venue: International journal of environmental research and public health
Year: 2020

This prospective study evaluated the predictive effect of difficulty in emotion regulation on the occurrence and remission of Internet addiction (IA) and determined whether IA has a role in changing emotion regulation among college students during a follow up period of 1 year. A total of 500 college students (262 women and 238 men) were recruited. In baseline and follow up investigations, the levels of IA and difficulty in emotion regulation were evaluated using the Chen Internet Addiction Scale and the Difficulties in Emotion Regulation Scale (DERS) respectively. The results indicated that the subscale of impulse control difficulties on the DERS predicted the incidence of IA during the follow up period of 1 year in male participants (t 2.875, p 0.005) whereas no subscale on the DERS predicted the remission of IA. IA did not predict the change in difficulties in emotion regulation. The subscale of impulse control difficulties on the DERS predicted the occurrence of IA in the college students and warrants early intervention.
An ANN Based Approach for Real Time Scheduling in Cloud Manufacturing
Year: 2020

The cloud manufacturing platform needs to allocate the endlessly emerging tasks to the resources scattered in different places for processing. However, this real time scheduling problem in the cloud environment is more complicated than that in a traditional workshop because constraints, such as type matching, task precedence, resource occupation, and logistics duration, need to be met, and the internal manufacturing plan of providers must also be considered. Since the platform aggregates massive manufacturing resources to serve large scale manufacturing tasks, the space of feasible solutions is huge, resulting in many conventional search algorithms no longer being applicable. In this paper, we considered resource allocation as the key procedure for real time scheduling, and an ANN (Artificial Neural Network) based model is established to predict the task completion status for resource allocation among candidates. The trained ANN model has high prediction accuracy, and the ANN based scheduling approach performs better than the preferred method in terms of the optimization objectives, including total cost, service satisfaction, and make span. In addition, the proposed approach has potential in the application for smart manufacturing or Industry 4.0 because of its high response performance and good scalability.
