INFLUÊNCIA DO FOTOSSENSIBILIZADOR AZUL DE METILENO DISSOLVIDO EM ETANOL NA TERAPIA FOTODINÂMICA ANTIMICROBIANA SOBRE O STATUS OXIDATIVO SISTÊMICO E COLÁGENO GENGIVAL EM MODELO EXPERIMENTAL DE PERIODONTITE

O objetivo deste estudo foi avaliar os efeitos da terapia fotodinâmica antimicrobiana (TFDa) usando o fotossensibilizador azul de metileno (AM) dissolvido em etanol sobre o status oxidativo sistemico, bem como sobre o conteudo de colageno gengival de ratos com periodontite. Ratos machos Wistar foram divididos aleatoriamente em dois grupos principais: CN (controle negativo; sem periodontite) e os animais restantes foram o grupo submetido a inducao de periodontite. No ultimo grupo, a ligadura de algodao foi colocada no primeiro molar inferior direito de cada animal em uma posicao subgengival para induzir a periodontite experimental. Os animais com periodontite foram subdivididos em grupos de acordo com o tratamento periodontal, como segue: grupo RAR (raspagem e alisamento radicular), TFDa I grupo (RAR + TFDa + AM dissolvido em agua), e grupo TFDa II (RAR + TFDa + AM dissolvido em etanol). Apos 7 dias, a ligadura foi removida e foram realizados os tratamentos periodontais. Aos 7, 15 e 30 dias, os ratos foram submetidos a eutanasia e foi removido o tecido gengival para analise morfometrica. Os eritrocitos foram usados para avaliar o status oxidativo sistemico. O status oxidativo demostrou maiores niveis de peroxidacao lipidica no grupo CP em 7, 15 e 30 dias, e indicou uma influencia protetora da TFDa II, nos eritrocitos, ja em 15 dias, observada a partir da elevacao dos niveis de defesa antioxidante sistemica. Os achados morfometricos mostraram que o grupo TFDa II restabeleceu o percentual de area total de colageno tambem em 15 dias, bem como recuperou a area de colageno tipo I no mesmo tempo. A partir deste estudo podemos sugerir que TFDa utilizada como um adjuvante ao tratamento padrao periodontal (RAR) aumenta a resposta protetora sistemica contra o estresse oxidativo induzido pela periodontite, facilitando e acelerando a cicatrizacao periodontal, particularmente quando o azul de metileno e solubilizado em etanol.
Comparing predictors of sexual harassment proclivity between Japanese and U.S. Men

The authors report on data showing evidence of both similarities and differences between Japanese and U.S. men regarding sexual harassment. Data indicate that there is substantial overlap in the traits and beliefs that predict a proclivity for sexual harassment in Japanese and U.S. men. However, Japanese men scored higher overall on sexual harassment proclivity, which was anticipated due to the relatively high degree of male dominance in Japan. Path analysis revealed that rape myth acceptance and a dimension of empathy (called personal distress) mediated this cross-cultural difference. The authors interpret the results as supporting the individual differences model of sexual harassment.
Electron Inertia Induce Nonlinear AcousticModes Near the Transonic Region in aMultispecies Plasma

In presence of multicomponent ionic plasma, more than one plasma sound waves are possible depending on the number of ions. In this work, we considered the presence of a negative ion along with the normal positive ion. Here we show that finite but weak electron inertial delay effect causes a resonant excitation of the ion acoustic solitons near the transonic zone, which depends on e i¨ i1,2 i© m mi« ratio. It has been seen that under such situation near the plasma sheath transonic zone, the KdV equations have complex coefficients. We have shown that even in presence of the complex coefficients soliton like solution can be derived only for infinitely long wavelength source perturbation. It is seen that when the negative ions mass becomes equal to that of a dust particle then similar excitation situation as in case of colloidal plasma can be retrieved. It is plausible that such kind of a resonant excitation may lead to acoustic turbulence near the plasma sheath edge. A detailed discussion of the nonlinear acoustic mode analyses in the transonic regime with negative ionic impurity using a hydrodynamic approach is presented
Baseline Concentrations of Toxic Elements in Metropolitan Park Soils of Taiwan

Twenty-four soil profiles were investigated at the urban parks in Taiwan to evaluate the contamination and sources of potentially toxic elements (Cd, Cr, Cu, Ni, Pb, Zn, As, and Hg). The experimental results indicted that a positive significant correlation existed between Pb and Zn (r = 0.38*, p < 0.05) and Ni and As (r = 0.35*, p < 0.05), and it suggests that these two groups of toxic elements were from different sources. Industrial activities in Kaohsiung city were considered to cause contamination with Cu (91.1 mg/kg in average) and Zn (126 mg/kg in average) in urban surface soils. High traffic flow in Taipei city leads a clear risk of Pb contamination (56.8 mg/kg in average) in the urban surface soils. Although observable concentrations of As (28.7 mg/kg in average) and Ni (12.8 mg/kg in average) were found in the recreational city, Yilan, most of both elements were still lower than the background levels in Taiwan and which are mainly released from parent materials, slate and argillite. _____________________________________________________________________________________________________________
Greek and Roman consolations: eight studies of a tradition and its afterlife

Ancient consolatory writings offer us a window onto alien forms of loss and grief, as experienced in a world where death happened, in most cases, much earlier and with less reliable warning than in developed countries today. Here, eight original studies explore the topic of bereavement in consolatory writings from ancient Greece, Rome, early medieval and Arabic society. David Scourfield examines consolation as a genre; James Chong-Gossard treats consolation in Greek tragedy, and the rejection of comfort; Han Baltussen studies the purpose and impact of Cicero's curious 'Consolation to Himself ' on the loss of his daughter. Marcus Wilson proposes a new interpretation of Seneca's consolatory writings; George Boys-Stones studies the Consolatio ad Apollonium as 'therapy for the dead'; David Konstan reflects on Lucian's Of Mourning and the consolation tradition. For later Antiquity and reception, Josef Lossl treats continuity and transformation of ancient Consolatio in Augustine of Hippo, while Peter Adamson addresses Arabic ethics and the limits of philosophical consolation. The collection offers unexpected results: consolation itself is on occasion rejected, philosophy deliberately marginalised, while much emerges which is unique and personal to the ancient individuals involved.
Shop 'til you drop: A coping mechanism for stressed university students?

Compulsive buying is a concerning problem affecting university students who are particularly vulnerable to experiencing anxiety and stress due to academic workloads, financial difficulties, and social isolation. The current study explores the relationship between compulsive buying behaviour, gender differences, anxiety, stress, and coping styles among university students. As expected, findings revealed female university students reported significantly higher levels of compulsive buying behaviour compared to male students, and students engaging in compulsive buying behaviours were significantly younger than non-compulsive buying students. Compared to university students who reported regular purchasing behaviours, university students who engaged in compulsive buying also reported significantly higher disengaged coping and stress levels, and significantly lower use of engaged coping. Disengaged coping also accounted for a significant amount of variance in compulsive buying behaviour. The findings suggest coping is a significant factor in the development of compulsive buying behaviour in university students who experience moderate levels of stress.
A method to separate and quantify the effects of indentation size, residual stress and plastic damage when mapping properties using instrumented indentation

Instrumented indentation is a convenient and increasingly rapid method of high resolution mapping of surface properties. There is, however, significant untapped potential for the quantification of these properties, which is only possible by solving a number of serious issues that affect the absolute values for mechanical properties obtained from small indentations. The three most pressing currently are the quantification of: the indentation size effect (ISE), residual stress, and pile-up and sink-in—which is itself affected by residual stress and ISE. Hardness based indentation mapping is unable to distinguish these effects. We describe a procedure that uses an elastic modulus as an internal reference and combines the information available from an indentation modulus map, a hardness map, and a determination of the ISE coefficient (using self-similar geometry indentation) to correct for the effects of stress, pile up and the indentation size effect, to leave a quantified map of plastic damage and grain refinement hardening in a surface. This procedure is used to map the residual stress in a cross-section of the machined surface of a previously stress free metal. The effect of surface grinding is compared to milling and is shown to cause different amounts of work hardening, increase in residual stress, and surface grain size reduction. The potential use of this procedure for mapping coatings in cross-section is discussed.

Buffer Sizing in Internet Routers

A brief summary of the effect of router buffers on network performance is presented. The previous buffer sizing works based on queuing theory are analyzed under two classes of traffic models, the models exhibiting long-range dependence and the models exhibiting short-range dependence. Another type of buffer sizing works are based on TCP models, and the rule of thumb, the small buffers rule, the drop-based buffers rule and the tiny buffers rule are the four main recent results in these works. The results of the four rules and some preliminary experiments to validate these rules are carefully summarized. Research directions and open problems are also discussed.
Mechanics Analysis of Composite Bolted Joints on the Process of Interference-fitting

This paper derived a closed-form solution for the stress distribution of composite plates with interference fit. A distinctive feature of the present analysis was that the relationship between bolt and hole was interference fit, in contrast to the commonly-used assumption of clearance fit and neat fit. Under the condition of plane stress, the stress distribution function of the composite hole was obtained by establishing the interference fit connection model between the linear elastic composite laminated plate and the blind bolted fastener. By comparing with the previous numerical analysis of the finite element model, the theoretical prediction solved by analytical method agreed with the results of FEM.
Avifauna Diversity in Kafa Biosphere Reserve: Knowledge and Perception of Villagers in Southwest Ethiopia

This study was carried out from 2013 to 2014 in Kafa biosphere reserve, southwest Ethiopia. We investigated and documented population status of bird diversity and the existing local community knowledge, attitude and practice associated with ecological significance to conservation of avian diversity. Point observation method was used to collect data on distribution and diversity of birds. Data were analyzed using descriptive Statistics, Chi-square test and one-way ANOVA. Questionnaire surveys were also made to collect qualitative data. A total of 474 birds fit in to 10 orders and 25 families were recorded. There were 398 residents, 56 winter migratory, 15 local migratory and 5 summer migratory birds. Shannon-winner indices of bird diversity for Kafa biosphere reserve, Decha, Chena, Dadiben, Gojeb wetland and Boka were 2.41, 2.71, 2.48, 2.24 and 1.68, while its evenness indices showed that 0.85, 0.94, 0.92, 0.90 and 0.86 respectively. We concluded that species richness, abundance and diversity reach higher values in larger and structurally more heterogeneous forest. Nine (31%) of the locals perceived that, avian conservation has ecological significance, while 20 (68%) were responded, is not essential, being depredators of chickens and crop pests. conservation of birds and its habitat should be integrated with the knowledge and practice of locals to establish participatory avian conservation.
On ideals in the enveloping algebra of a locally simple Lie algebra

We study (two-sided) ideals $I$ in the enveloping algebra $\U(\frak g_\infty)$ of an infinite-dimensional Lie algebra $\frak g_\infty$ obtained as the union (equivalently, direct limit) of an arbitrary chain of embeddings of simple finite-dimensional Lie algebras $\frak g_1\to\frak g_2\to. \to\frak g_n\to. $ with $\lim\limits_{n\to\infty}\dim\frak g_n=\infty$. Our main result is an explicit description of the zero-sets of the corresponding graded ideals $\gr I$. We use this description and results of A. Zhilinskii to prove Baranov's conjecture that, if $\frak g_\infty$ is not diagonal in the sense of A. Baranov and A. Zhilinskii, then $\U(\frak g_\infty)$ admits a single non-zero proper ideal: the augmentation ideal. Our study is based on a complete description of the radical Poisson ideals in ${\bf S}^\cdot(\frak g_\infty)$ and their zero-sets. We then discuss in detail integrable ideals of $\U(\frak g_\infty)$, i.e. ideals $I\subset\U (\frak g_\infty)$ for which $I\cap\U (\frak g_n)$ is an intersection of ideals of finite-codimension in $\U(\frak g_n)$ for any $n\ge 1$. We present a classification of prime integrable ideals based on work of A. Zhilinskii. For $\frak g_\infty\cong\frak{sl}_\infty, \frak{so}_\infty$, all zero-sets of radical Poisson ideals of ${\bf S}^\cdot(\frak g_\infty)$ arise from prime integrable ideals of $\U(\frak g_\infty)$. For $\frak g_\infty\cong\frak{sp}_\infty$ only "half" of the zero-sets of Poisson ideals ${\bf S}^\cdot(\frak g_\infty)$ arise from integrable ideals of $\U(\frak g_\infty)$.
CORRELATION OF MICROVESSEL DENSITY AND EXPRESSION OF P53 IN ORAL SQUAMOUS CELL CARCINOMA

OBJECTIVES: The objectives of this study were to analyze the expression of the involved antibodies to p53 and CD31 and to verify the relation with histological grade of malignancy. METHODOLOGY: Eighteen cases of SCC had been studied, graduated for the system proposed by Anneroth et al (1). The p53 immunostaining was counting carried using ten fields for slide observing of 1000 positive and negative cells. The mensuration of angiogenesis was made through the counting of blood vessels and of the density of vases, which corresponds the occupied surface for field. RESULTS: 100% of the studied cases were positive for p53 with an average of 76% of the tumoral cells with nuclear protein accumulation and 71% for the CD31. The relation between the expression of p53 and CD31 and the histological gradation of malignancy was not observed. A positive correlation was observed in all the cases between the expression of p53 and an increase of the microvascular density. CONCLUSION: An increased p53 possitiveness and its association with angiogenesis in oral SCC is suggested in this study.
Global Compactness Properties of Semilinear Elliptic Equations with Critical Exponential Growth

Abstract Sequences of positive solutions to semilinear elliptic equations of critical exponential growth in the plane either are precompact in the Sobolev H 1 -topology or concentrate at isolated points of the domain. For energies allowing at most single-point blow-up, we establish a universal blow-up pattern near the concentration point and uniquely characterize the blow-up energy in terms of a geometric limiting problem.
Using Longitudinal Data to Increase Community College Student Success: A Guide to Measuring Milestone and Momentum Point Attainment. CCRC Research Tools No. 2.

Most community colleges and many state community college systems collect extensive data on individual students. Unfortunately, these data are often underutilized in efforts to improve outcomes for individual students and colleges. Community college systems and their constituent colleges have only recently come to realize the potential for using student unit record (SUR) data for more than reporting student enrollments and program graduates. By organizing these data into termby-term student transcript records over several years and incorporating individual student demographic data, colleges and states can create a powerful resource for understanding patterns of student progression and achievement over time. Understanding how students actually progress through their college programs is essential in developing strategies and choosing appropriate interventions to improve student outcomes. The challenge is to build expertise and capacity in college and state agency research departments to transform raw SUR data into meaningful information of practical use for policymakers and practitioners.
Biological effect of sweet wormwood, Artemisia annua methanol extracts and essential oil against Helicoverpa armigera Hub. (Lepidoptera: Noctuidae)

Methanolic extract of different parts of Artemisia annua, (Leaf, shoot, and seed) and essential oil were evaluated for their effect on growth and development of larvae of Helicoverpa armigera. The experiments were done by the incorporation of different extracts and essential oil in semisynthetic diet at two percent concentration. Among leaf, stem, seed extract and essential oil treatments the larval weight was reduced by diet containing essential oil (69.71%) and leaf extract of A. annua (60.21%) as compared to control. The prolongation of larval and pupal period and an average more than fifty percent IGR activity was recorded by the treatments of A. annua extract and essential oil. The growth retardation, including reduced weight and prolongation of larvae may possibly interrupt the production of insect hormoneecdysone level in insect body which also delayed the pupation. Physiological effects found in treated larvae included formation of larva pupa intermediate and adultoids.
Gender differences in occupational mobility and segregation at the labor market: The case of Russian economy

This research analyses the influence of the differences in occupational mobility of men and women on gender segregation at the Russian labor market during 1985–2002. At the basis of the occupational mobility model which takes into account the gender differences in social roles, we estimate the input that individual characteristics and parameters of current occupation, characteristics of the local labor market make into probability of occupational mobility of employees of the different genders and probability of choice between different "gender-dominated" occupations, as well. The results prove that segregation decrease through occupational mobility is possible depending on increasing competitiveness of women at the labor market and eliminating factors preventing their access to employment in the private sector. Positive returns to occupational mobility in terms of wage growth were discovered for both gender groups.
Event-based analysis of the association between alcohol use and unsafe sex in seven sub-Saharan African countries

Aims : To examine the association between alcohol consumption at last sex and unsafe sex in seven countries in sub-Saharan Africa. Design : Multivariable logistic regression of unsafe sex was performed using cross-sectional data with a stratified sample design from seven countries. Setting : The study uses data from the Demographic and Health Surveys of Lesotho, Kenya, Mozambique, Swaziland, Uganda, Zambia, and Zimbabwe. Participants : Men and women age 15–49 years with data available on alcohol consumption and who have had sex in the last 12 months were included in the analysis. Measures : The main independent variable is alcohol consumption at last sex with a non-cohabiting partner. Findings : The analysis has shown that alcohol consumption was a strong predictor of unsafe sex for all surveys except for women in Kenya. Age and number of sexual partners were also strong predictors of unsafe sex. Conclusions : The findings indicate that there is a positive link between alcohol consumption and unsafe sex in all countries except for Kenya among women. The inconsistent finding in Kenya requires further study. One of the main limitations of the analysis is the low number of observations found for women and men who reported drinking at last sex with a non-cohabiting partner.
Guaranteed maximum price (GMP) contracts in practice: a case study of a private office development project in Hong Kong

Purpose – This paper aims to investigate the operational mechanism, project performance, motives behind, benefits, difficulties and success factors of adopting the GMP scheme based on a real-life case study of “Chater House”, an international Grade A private office project in Hong Kong. Design/methodology/approach – The case project was analysed by means of the related project documentation and a series of face-to-face interviews with the relevant senior project representatives. Findings – All the interviewed key project stakeholders perceived that the GMP contract helped achieve competitive price, value for money and superior quality of products as well as provided stronger incentives to innovation and cost saving. The case study revealed that the overall success of this GMP project was underpinned by the following key attributes including: (1) implementation of partnering concepts; (2) reasonable share of cost savings; (3) early involvement of contractor in design development; (4) right selection of qualified subcontractors; (5) establishment of adjudication committee; and (6) open-book accounting arrangement. Practical implications – The lessons learned from this successful GMP project could help the industrial practitioners to minimise the detriments brought about by potential difficulties, and maximise the benefits gained from implementing GMP philosophy. Such an improved understanding could well generate essential strategies to eradicate the root causes of adverse project performance, win-lose consequence and confrontational working relationship amongst various project stakeholders. Originality/Value – The research study has provided solid groundwork for client bodies and contracting organisations to develop a best practice framework for implementing successful GMP schemes in future construction.
