    The FORTRAN codes COREL, RASE4 and DAMG2 can be used to calculate quantities associated with ion implantation range and energy deposition distributions within an amorphous target, or for ions incident far from low index directions and planes in crystalline targets. RASE4 calculates the projected range, R/sub p/, the root mean square spread in the projected range, ΔR/sub p/, and the root mean square spread of the distribution perpendicular to the projected range ΔR/sub perpendicular to/. These parameters are calculated as a function of incident ion energy, E, and the instantaneous energy of the ion, E'. They are sufficient to determine the three dimensional spatial distribution of the ions in the target in the Gaussian approximation when the depth distribution is independent of the lateral distribution. RASE4 can perform these calculations for targets having up to four different component atomic species. The code COREL is a short, economical version of RASE4 which calculates the range and straggling variables for E' = 0. Its primary use in the present package is to provide the average range and straggling variables for recoiling target atoms which are created by the incident ion. This information is used by RASE4 in calculating the redistribution of deposited energy by the target atom recoils. The code DAMG2 uses the output from RASE4 to calculate the depth distribution of energy deposition into either atomic processes or electronic processes. With other input DAMG2 can be used to calculate the depth distribution of any energy dependent interaction between the incident ions and target atoms. This report documents the basic theory behind COREL, RASE4 and DAMG2, including a description of codes, listings, and complete instructions for using the codes, and their limitations

    Full Text Available Background: Hypertension is a chronic condition of concern due to its role in the causation of coronary heart disease, stroke and other  complications. It is one of the major risk factors for cardio-vascular mortality accounting for 20-50% of all deaths. Children with higher blood pressure tend to maintain those levels during adulthood also. Objectives:  Assess the prevalence of hypertension in adolescents (11-18 years, its risk factors and their socio-demographic co-relates. Material and Method:  Prevalence of adolescent hypertension in previous studies was 7% and the sample size accordingly came to be 1314 with a relative precision of 20%. Multistage sampling technique was used. Half each of the sample size was covered in urban and rural areas . Households in the selected colonies in the urban areas and villages were randomly selected and the adolescents interviewed and examined. Their responses were recorded on a pretested questionnaire and results drawn. Data were analysed using Epi-info and SPSS and chi-square test applied. Results:   Prevalence of adolescent hypertension was found to be 5.3% (72 out of 1340; significantly associated with type of family (P<0.001, educational status (P<0.001, occupation (P<0.001, BMI (P<0.01, and smoking habit (P<0.05. However, no relationship of hypertension was found with salt intake, type of diet, exercise, alcohol consumption, stress and family history of hypertension. Conclusion: Socio-demographic factors certainly influence the prevalence and probability of occurrence of adolescent hypertension but the effect of established risk factors (for adult hypertension needs to be further evaluated for adolescent hypertension and more studies are required in this area.

    Full Text Available Objectives : Orofacial manifestations (OFMs are seen early in the course of HIV disease in children and can also act as indicators for the presence of the disease. The objective of the study were to find the prevalence of OFMs of HIV in infected children, co-relate them with their CD4 counts and establish whether OFMs could be used as markers for disease progression. Materials and Methods : Using the diagnostic criteria recommended by the European Collaborative Clearinghouse (ECC on oral problems related to HIV infection and WHO Collaborating Centre on oral manifestations of the HIV, 48 HIV-infected children were examined at the baseline and their CD4 counts were obtained. A follow-up was conducted 6 months later. Chi-Square test was used to analyse the data obtained. Results : OFM showed a high prevalence in HIV-infected children. The degree of immunosuppression was found to co-relate with the presence of OFMs. But, it could not be established that the presence of OFMs could be a marker for HIV disease progression. Conclusion : The results of our study indicated a high prevalence of OFMs in HIV-infected South Indian children. A decline in CD4 counts was found to be associated with more number of OFMs. However, we were unable to establish OFMs as markers for HIV disease progression. The sample size in our study being about 48 patients and the variability in the initiation and duration of HAART therapy, use of other drugs not being considered, may have an influence on the result of our study. Larger population groups, with parameters such as nutritional status and HAART initiation included, can probably give a more conclusive result..

    Dysautonomia and non-motor symptoms (NMS) in Parkinson's disease (PD) are frequent, disabling and reduce quality of life of patient. There is a paucity of studies on autonomic dysfunction in PD in Indian population. The study aimed to evaluate autonomic dysfunction in PD patients and co-relate the findings with severity of PD and Non-Motor Symptoms Scale (NMSS) score. We evaluated autonomic function in 30 diagnosed patients of PD (age 55-70 years) and 30 healthy age-matched controls by 3 min deep breathing test (DBT). NMSS was used to identify non-motor symptoms and Hoehn and Yahr (HY) Scale to grade severity of PD. The DBT findings were co-related with severity of PD (HY staging) and NMSS score. DBT was found to be abnormal in 40% while it was on borderline in 33.3% of PD patients. There was a statistically significant difference (psymptom. A negative co-relation was found between results of deep breathing test and clinical severity of disease and NMSS score. Abnormalities of autonomic function and NMS were integral and present across all the stages of PD patients. Early recognition and treatment of these may decrease morbidity and improve quality of life of PD patients.

    Full Text Available Purpose of the Study: Purpose of the study is to investigate whether the variables associated with the permanent mandibular third molar (PMM3 and arch dimensions could be co-related and significantly differentiated between a fully erupted and mesially impacted PMM3 among a set of Indian population. Study Design: A standardized panoramic radiograph was taken of subjects of age 21 years and above. Patients with missing tooth from mandibular arch, subjects undergoing or having history of orthodontic treatment, subjects having disto-angular, horizontal or vertical impacted PMM3 were excluded from the study. Subjects were divided into 2 groups: (1 mesially impacted PMM3 and (2 vertically erupted PMM3. Following measurements were taken from acetate paper tracing of standardized panoramic radiograph: (1 Angulation of long axis of PMM3 to permanent mandibular second molar (theta (2 Angulation of PMM 3 to base of mandible (theta 2 (3 Gonial angle (theta 3 (4 Mesio-distal width of PMM 3 (5 Retro molar space. From these measurements Ganss ratio (retro molar space /PMM3 crown width. was calculated. Results and Conclusion: Results revealed that angle theta 1, angle theta 2, retro molar space and Ganss ratio were positively co-related and highly significant variables associated with the mesially and vertically erupted teeth as measured on panoramic radiograph. Using these variables a long-term study can be carried out to predict the ultimate position of lower third molar in the arch so that if there is a probability of the tooth being impacted at a later age, a prophylactic germectomy can be performed at an early age.

    Full Text Available ABSTRACT Frequently degraded pastureland characterized by low soil fertility and compacted surface is the basic environment of Brazilian livestock. The physical and chemical characterization of soil and its co-relationship with forage production are determining factors for performance of animals raised on pasture. The objective was to analyze the forage production of Urochloa decumbens grass correlated, linearly and spatially, with physical and chemical attributes of a savannah soil in Selvíria - MS, Brazil. A geostatistical web was introduced for the collection of soil and plant data, with 120 sampling sites within an area of 56.09 ha. The descriptive analysis of the data was undertaken and linear co-relationships, both simple and multiple, were established between plant and soil properties. Semivariograms were modeled and their respective krigings and cross-validations obtained, coupled to co-krigings (plant and soil. Production of dry matter and crude protein rates of U. decumbens may be estimated by regressions and the mechanical resistance to penetration and gravimetric humidity of the soil evaluated. Since organic matter rate and the gravimetric humidity of the soil are co-related spatially with the rate of crude protein of U. decumbens, they are the best factors to calculate or increase the forage crude protein rate.

    Schizophrenia is associated with impaired neurodevelopment as indexed by lower premorbid IQ. We examined associations between erythrocyte sedimentation rate (ESR), a marker of low-grade systemic inflammation, IQ, and subsequent schizophrenia and other non-affective psychoses (ONAP) to elucidate the role of neurodevelopment and inflammation in the pathogenesis of psychosis. Population-based data on ESR and IQ from 638 213 Swedish men assessed during military conscription between 1969 and 1983 were linked to National Hospital Discharge Register for hospitalisation with schizophrenia and ONAP. The associations of ESR with IQ (cross-sectional) and psychoses (longitudinal) were investigated using linear and Cox-regression. The co-relative analysis was used to examine effects of shared familial confounding. We examined mediation and moderation of effect between ESR and IQ on psychosis risk. Baseline IQ was associated with subsequent risk of schizophrenia (adjusted HR per 1-point increase in IQ = 0.961; 95% confidence interval (CI) 0.960-0.963) and ONAP (adjusted HR = 0.973; 95% CI 0.971-0.975). Higher ESR was associated with lower IQ in a dose-response fashion. High ESR was associated with increased risk for schizophrenia (adjusted HR = 1.14; 95% CI 1.01-1.28) and decreased risk for ONAP (adjusted HR = 0.85; 95% CI 0.74-0.96), although these effects were specific to one ESR band (7-10 mm/hr). Familial confounding explained ESR-IQ but not ESR-psychoses associations. IQ partly mediated the ESR-psychosis relationships. Lower IQ is associated with low-grade systemic inflammation and with an increased risk of schizophrenia and ONAP in adulthood. Low-grade inflammation may influence schizophrenia risk by affecting neurodevelopment. Future studies should explore the differential effects of inflammation on different types of psychosis.

    The authors sought to determine whether pregnancy is an intrinsic motivator for cessation of drug abuse. The authors conducted prospective cohort, co-relative, co-spouse, and within-person analyses of registration for drug abuse during pregnancy among Swedish women born between 1980 and 1990 who gave birth between ages 20 and 35 (N=149,512). Drug abuse was assessed from medical, criminal, and pharmacy registries. In the population, rates of drug abuse were lower during pregnancy (unadjusted odds ratio=0.67, 95% CI=0.60, 0.74). Compared with population results, the negative association between pregnancy and drug abuse was moderately stronger in cousins (odds ratio=0.49, 95% CI=0.39, 0.62) and substantially stronger in siblings (odds ratio=0.35, 95% CI=0.24, 0.51) discordant for pregnancy. The estimated odds ratio for drug abuse in pregnancy-discordant monozygotic twins was even stronger, at 0.17 (95% CI=0.10, 0.31). Within individuals, the odds ratio for drug abuse while pregnant compared with an equivalent prepregnancy interval was similar to that seen in pregnancy-discordant monozygotic twins, at 0.22 (95% CI=0.19, 0.26). Compared with cohabiting fathers, mothers had a greater reduction in risk for drug abuse during pregnancy (odds ratio=0.40, 95% CI=0.34, 0.47). Pregnancy was more protective in women with low parental education and without a cohabiting, actively drug-abusing father. Compared with prepregnancy baseline, within-individual analyses indicate that risk for drug abuse is also substantially reduced in the postpartum period, for example, the odds ratio for postpartum days 0-242 was 0.13 (95% CI=0.11, 0.16). Risk for drug abuse in women is substantially reduced during pregnancy. Multiple analyses suggest that this association is largely causal, suggesting that pregnancy is indeed a strong intrinsic motivator for drug abuse cessation. Similar strong protective effects may be present in the immediate postpartum period. Our results have implications for our

    1 - Description of problem or function: COREL calculates the final average projected range, standard deviation in projected range, standard deviation in locations transverse to projected range, and average range along path for energetic atomic projectiles incident on amorphous targets or crystalline targets oriented such that the projectiles are not incident along low index crystallographic axes or planes. RASE4 calculates the instantaneous average projected range, standard deviation in projected range, standard deviation in locations transverse to projected range, and average range along path for energetic atomic projectiles incident on amorphous targets or crystalline targets oriented such that the projectiles are not incident along low index crystallographic axes or planes. RASE4 also calculates the instantaneous rate at which the projectile is depositing energy into atomic processes (damage) and into electronic processes (electronic excitation), the average range of target atom recoils projected onto the direction of motion of the projectiles, and the standard deviation in the recoil projected range. DAMG2 calculates the distribution in depth of the energy deposited into atomic processes (damage), electronic processes (electronic excitation), or other energy-dependent quality produced by energetic atomic projectiles incident on amorphous targets or crystalline targets oriented such that the projectiles are not incident along low index crystallographic axes or planes. 2 - Method of solution: COREL: The truncated differential equation which governs the several variables being sought is solved through second-order by trapezoidal integration. The energy-dependent coefficients in the equation are obtained by rectangular integration over the Thomas-Fermi elastic scattering cross section. RASE4: The truncated differential equation which governs the range and straggling variables is solved through second-order by trapezoidal integration. The energy

    2003-03-01

    Ultrafast photoinduced dynamics of electronic excitation in molecular dimers is drastically affected by dynamic reorganization of of inter- and intra- molecular nuclear configuration modelled by quantized nuclear degree of freedom [1]. The dynamics of the electronic population and nuclear coherence is analyzed with help of both numerical solution of the chain of coupled differential equations for mean coordinate, population inversion, electronic-vibrational correlation etc.[2] and by propagating the Gaussian wavepackets in relevant adiabatic potentials. Intriguing results were obtained in the approximation of small energy difference and small change of nuclear equilibrium configuration for excited electronic states. In the limiting case of resonance between electronic states energy difference and frequency of the nuclear mode these results have been justified by comparison to exactly solvable Jaynes-Cummings model. It has been found that the photoinduced processes in dimer are arranged according to their time scales:(i) fast scale of nuclear motion,(ii) intermediate scale of dynamical redistribution of electronic population between excited states as well as growth and dynamics of electronic -nuclear correlation,(iii) slow scale of electronic population approaching to the quasiequilibrium distribution, decay of electronic-nuclear correlation, and diminishing the amplitude of mean coordinate oscillations, accompanied by essential growth of the nuclear coordinate dispersion associated with the overall nuclear wavepacket width. Demonstrated quantum-relaxational features of photoinduced vibronic dinamical processess in molecular dimers are obtained by simple method, applicable to large biological systems with many degrees of freedom.

    The maintenance of 40 MWth research reactor, Cirus has been carried out for over 30 years following the time based maintenance schedule. With the commissioning of indigenously built 100 MWth nuclear research reactor Dhruva in the year 1985, a systematic work on condition monitoring has been commissioned. Apart from process parameters, which are recorded on hourly basis, vibration, noise, temperature, kurtosis etc. are measured for assessment of condition of pumps. The bearings of flywheel assembly of main pumps, Dhruva broke down almost abruptly during the initial years after first commissioning. The regular measurements of vibration level and kurtosis have greatly helped in avoiding breakdown. In a recent case one newly procured herringbone gear box (300 hp, 1475/1760 rpm) for the primary coolant pump was showing high vibration. In further checking using Fast Fourier Transform (FFT) analyser in a time domain plot the gear teeth damage was indicated. The pump was shut down for inspection and when the gear box was dismantled teeth were found broken. An attempt has been made in this paper to discuss a few interesting field experiences with condition monitoring and correlating field observations on pumps. (author). 3 figs

    1994-01-01

    For many years now short-range correlations (SRC) in nuclei have been considered as an essential feature of the nuclear wave function. At high energy (e,e') reactions, where Q 2 > 1 (GeV/c) 2 , x = Q 2 /2mq o > 1 and 1 GeV > q o > 300 ∼ 400 MeV the scattering from low momentum nucleons is kinematically suppressed and there the evidence of SRC expected to be more prominent. These reactions have been intensively investigated during the last decade or so at SLAC on both light and heavy nuclei. The above kinematics allows one to compute the cross section through the processes local in space. To explain this the authors analyse the representation of the cross section as a Fourier transform of the commutator of electromagnetic currents and see that the major contribution in the cross section is given by the region of integration

    Full Text Available The presence of fluvial morphology in the Transylvanian Basin, in form of an alternation of water divides and valley corridors, indicates favourable conditions for the genesis of geomorphologic processes. Under this aspect two sections stand out within this type of processes: river beds and slopes. In this paper, the emphasis is on the processes, developed on slopes. Water erosion and mass movement processes can be observed on their surface. From all mass movement processes, the emphasis will be put on the landslides. They will be observed in correlation with the morphologic and functional units of the slopes from different regional units of Transylvanian Basin. Eight case studies were taken into consideration regarding this aspect. Thus, we noticed that landslides particularly develop in the median part of the slopes which is corresponding to the maximum processual dynamic and transfer unit.

    Full Text Available Background: The ABO blood group system is of prime significance in red cell transfusion and organ transplantation. However, ABO compatibility is not critical in allogenic hemopoietic stem cell transplantation (HSCT and approximately 40-50% of hemopoietic stem cell transplants are ABO incompatible. This incompatibility may be major, minor or bi-directional. Though there are descriptions of transfusion practice and protocols in ABO incompatible HSCT, there are considerable variations and transfusion support in these patients can be very challenging. Aims: The immunohematologic observations in two cases of bi-directional ABO incompatible HSCT have been described, and clinico-serologic correlation has been attempted. Materials and Methods: In both cases, peripheral blood stem cell harvests were obtained using the Cobe spectra cell separator. Immunohematologic assessments in the donor and recipient were done as a part of pre HSCT evaluation. Both the standard tube technique and column agglutination method (Ortho Biovue Micro Bead System was used. Antibody screen was done by column agglutination method using three cell panel (Surgiscreen cells. Isoagglutinin titration was done by the master dilution method and standard validated techniques were used. Results: The pattern of laboratory findings in the two cases was different and so were the clinical outcomes. Although there was early engraftment in the first case, the second case developed pure red cell aplasia and this was well-reflected in the immunohematologic assessments. Conclusion: Immunohematologic assessment correlated well with the clinical picture and could be used to predict clinical outcome and onset of complications in ABO incompatible HSCT.

    For many years now short-range correlations (SRC) in nuclei have been considered as an essential feature of the nuclear wave function. At high energy (e,e{prime}) reactions, where Q{sup 2} > 1 (GeV/c){sup 2}, x = Q{sup 2}/2mq{sub o} > 1 and 1 GeV > q{sub o}> 300 {approximately} 400 MeV the scattering from low momentum nucleons is kinematically suppressed and there the evidence of SRC expected to be more prominent. These reactions have been intensively investigated during the last decade or so at SLAC on both light and heavy nuclei. The above kinematics allows one to compute the cross section through the processes local in space. To explain this the authors analyse the representation of the cross section as a Fourier transform of the commutator of electromagnetic currents and see that the major contribution in the cross section is given by the region of integration.

  11. SOCIAL AND ECONOMIC IMPACTS OF WIND POWER IN CORELATION WITH THE FINANCIAL CRISES

    Full Text Available Given the present day and age we live in, it is vital that the world considers the various natural resources available to us and how to best make use of them. Furthermore, it is imperative nowadays to look at the many environmentally friendly energy sources which will reduce the ill effects of global warming and provide a host of economic and social benefits too. One such beneficial resource is wind and the consequent conversion of wind energy into electricity. In fact, the advantages of wind energy are so immense that even the government has begun promoting it. Since generating electricity from wind doesn't emit any green house gases or produce any particulate emissions, it massively reduces the rate of global climate change, and at the same time doesn't contaminate our water resources such as lakes and reservoir.Wind energy provides security and stability in the national consumer energy market. By reducing a nations dependency on foreign fossil fuels, such as coal and natural gas, spikes in fossil fuel costs or other supply disruptions will not have as much of an adverse impact on the national economy. Also the price of wind energy is relatively stable because there are no fuel costs, which is a major operating expense for most coal and gas fired electric generation facilities. Although wind farms occupy large swaths of land, wind turbine towers themselves take up less space, only a few meters at their base. This leaves space to utilize the land around the turbine tower for several other purposes, such as ranching or agriculture. The application of advanced technologies has succeeded in making the conversion of wind energy much more resourceful and well-organized. Furthermore, wind is a proven clean, free and renewable form of energy that preserves our natural resources. Wind energy conserves water resources as wind farms virtually require no cooling, as opposed to natural gas, coal and nuclear power plants that require a tremendous amount of water for cooling. In fact, electricity generation is the leading contributor to water withdrawals from our nation's water reservoirs. Since wind turbines come in an array of different sizes, they are a great resource to generate energy in remote locations to support varying population levels. The use of wind energy reduces Greenhouse Gas emissions, and increases security and stability by diversifying the national electricity portfolio. Apart from environmental profits, there are many social and economic advantages too in promoting wind energy. One of these is that the promotion of wind energy assists in revitalizing rural economies, thereby creating jobs at the ground level, such as assembly workers, surveyors, engineers, lawyers, bankers, technicians, to name just a few. In doing so, it also benefits local communities, mainly in the form of property tax revenues and new types of income for landowners through land lease payments.

    Full Text Available Tourism – and specially nature tourism - is an area, where the interaction between the tourists and environment is very intensive. Tourists are sensitive to the beauty and purity of the environment, but at the same time, the environmental impact of their presence in nature is marked. In order to maintain the beauty and purity of the environment a number of environmental threats are to be alleviated. Further, it seems to be necessary to decrease/regulate the number of tourists, or a set of costly cleaning and revitalising operations are to be implemented. The paper analyses the data available on the tourism related load of one of the most beautiful areas in Slovakia – the „Slovak paradise“, located in E. Slovakia.

    Objective To clarify the magnitude and nature of the relationship between divorce and risk for alcohol use disorder (AUD). Method In a population-based Swedish sample of married individuals (n=942,366), we examined the association between divorce or widowhood and risk for first registration for AUD. AUD was assessed using medical, criminal and pharmacy registries. Results Divorce was strongly associated with risk for first AUD onset in both men (HR=5.98, 95% CI, 5.65–6.33) and women (HR=7.29, 6.72–7.91). We estimated the HR for AUD onset given divorce in discordant monozygotic twins to equal 3.45 and 3.62 in men and women, respectively. Divorce was also associated with an AUD recurrence in those with AUD registrations before marriage. Furthermore, widowhood increased risk for AUD in men (HR=3.85, 2.81–5.28) and women (HR=4.10, 2.98–5.64). Among divorced individuals, remarriage was associated with a large decline in AUD in both sexes: males 0.56, 0.62–0.64 and females 0.61, 0.55–0.69. Divorce produced a greater increase in first AUD onset in those with a family history of AUD or with prior externalizing behaviors. Conclusions Spousal loss through divorce or bereavement is associated with a large enduring increased AUD risk. This association likely reflects both causal and non-causal processes. That the AUD status of the spouse alters this association highlights the importance of spouse characteristics for the behavioral health consequences of spousal loss. The pronounced elevation in AUD risk following divorce or widowhood, and the protective effect of remarriage against subsequent AUD, speaks to the profound impact of marriage on problematic alcohol use.

    Full Text Available Background: Chronic obstructive pulmonary disease (COPD has considerable effects on cardiac functions, including those of the right ventricle, left ventricle, and pulmonary blood vessels. Most of the increased mortality associated with COPD is due to cardiac involvement. Echocardiography provides a rapid, noninvasive, portable, and accurate method to evaluate the cardiac changes. Aims: To assess the cardiac changes secondary to COPD by echocardiography and to find out the correlation between echocardiographic findings and severity of COPD, if there is any. Materials and Methods: A total 40 of patients of COPD were selected and staged by pulmonary function test (PFT and evaluated by echocardiography. Results: On echocardiographic evaluation of COPD, 50% cases had normal echocardiographic parameters. Measurable tricuspid regurgitation (TR was observed in 27/40 cases (67.5%. Pulmonary hypertension (PH, which is defined as systolic pulmonary arterial pressure (sPAP > 30 mmHg was observed in 17/27 (63% cases in which prevalence of mild, moderate, and severe PH were 10/17 (58.82%, 4/17 (23.53%, and 3/17 (17.65%, respectively. The frequencies of PH in mild, moderate, severe, and very severe COPD were 16.67%, 54.55%, 60.00%, and 83.33%, respectively. Right atrial pressure was 10 mmHg in 82.5% cases and 15 mmHg in 17.5% cases. Cor pulmonale was observed in 7/17 (41.17% cases; 7.50% cases had left ventricle (LV systolic dysfunction and 47.5% cases had evidence of LV diastolic dysfunction defined as A ≥ E (peak mitral flow velocity of the early rapid filling wave (E, peak velocity of the late filling wave caused by atrial contraction (A on mitral valve tracing. Left ventricle hypertrophy was found in 22.5% cases. Conclusion : Prevalence of PH has a linear relationship with severity of COPD and severe PH is almost associated with cor pulmonale. Echocardiography helps in early detection of cardiac complications in COPD cases giving time for early interventions.

    Full Text Available Hydraulic conductivity is a basic element in the advancement of knowledge of a geological environment in both the flow and transport processes of pollutants for conservation projects, managementand environmental management and also for the development of public policies for protection of ecosystems, among others. The aim of this paper is to obtain the hydraulic conductivity (K and the finescontent (C of saturated granular half using two empirical laws. One correlates the electrical conductivity of saturated granular media σo and water saturated σw which depends on the formation factor(F, cation exchange capacity (CEC and the fines content in the saturated soil. Using data obtained from materials of 18 samples from 6 wells the relationships between F-C and CEC-C were obtained,so the equation reduces to a σo function in terms of σw and C, with a correlation coefficient of R = 0.97. A second experimental law is the one that results from the experimental relationship between K and C,being 1.4054 K 0.1804.C with a correlation coefficient of R = 0.96. From both experimental expressions relationships between K and C, a and C,and C are created so from every pair knowing one of them you get to know the other one. Under the scheme outlined electrical conductivity sections for the saturated medium and fines content are obtained,finding that the groundwater in the study area consists of a thin top layer and beneath it there is a predominantly sandy environment.

    Associations between childhood infection, IQ, and adult nonaffective psychosis (NAP) are well established. However, examination of sensitive periods for exposure, effect of familial confounding, and whether IQ provides a link between childhood infection and adult NAP may elucidate pathogenesis of psychosis further. To test the association of childhood infection with IQ and adult NAP, to find whether shared familial confounding explains the infection-NAP and IQ-NAP associations, and to examine whether IQ mediates and/or moderates the childhood infection-NAP association. Population-based longitudinal cohort study using linkage of Swedish national registers. The risk set included all Swedish men born between 1973 and 1992 and conscripted into the military until the end of 2010 (n = 771 698). We included 647 515 participants in the analysis. Hospitalization with any infection from birth to age 13 years. Hospitalization with an International Classification of Diseases diagnosis of NAP until the end of 2011. At conscription around age 18 years, IQ was assessed for all participants. At the end of follow-up, the mean (SD) age of participants was 30.73 (5.3) years. Exposure to infections, particularly in early childhood, was associated with lower IQ (adjusted mean difference for infection at birth to age 1 year: -1.61; 95% CI, -1.74 to -1.47) and with increased risk of adult NAP (adjusted hazard ratio for infection at birth to age 1 year: 1.19; 95% CI, 1.06 to 1.33). There was a linear association between lower premorbid IQ and adult NAP, which persisted after excluding prodromal cases (adjusted hazard ratio per 1-point increase in IQ: 0.976; 95% CI, 0.974 to 0.978). The infection-NAP and IQ-NAP associations were similar in the general population and in full-sibling pairs discordant for exposure. The association between infection and NAP was both moderated (multiplicative, β = .006; SE = 0.002; P = .02 and additive, β = .008; SE = 0.002; P = .001) and mediated (β = .028; SE = 0.002; P IQ. Childhood infection had a greater association with NAP risk in the lower, compared with higher, IQ range. Early childhood is a sensitive period for the effects of infection on IQ and NAP. The associations of adult NAP with early-childhood infection and adolescent IQ are not fully explained by shared familial factors and may be causal. Lower premorbid IQ in individuals with psychosis arises from unique environmental factors, such as early-childhood infection. Early-childhood infections may increase the risk of NAP by affecting neurodevelopment and by exaggerating the association of cognitive vulnerability with psychosis.

    2017-01-01

    Full Text Available Background: Menorrhagia is defined subjectively as heavy menses lasting for more than 7 days or objectively as a mean menstrual blood loss of >80 ml during three consecutive menses. It can occur due to organic causes like fibroids, polyps, cervitis, ovarian cysts, adnexal masses, uterine cancer or systemic causes like hypothyroidism, bleeding disorders, pregnancy and prolapse or dysfunctional uterine bleeding. Body Mass Index may have a correlation with menorrhagia. Aim and Objectives: This study was carried out in western Nepalese women to assess the causes of menorrhagia; report most common symptoms associated with it and assess the correlation of causes of menorrhagia with BMI. Material and Methods: A hospital based observational study was carried out between 1st January 2015 to 31st January 2016 on 157 volunteer women who consulted the Department of Gynaecology and Obstetrics for menorrhagia. Data were collected via interview and with the help of a questionnaire. Height and weight of the patients were recorded for calculation of BMI. The data was analysed with SPSS 17 vesion. Mean,Standard Deviation and Chi-square test were applied and p value <0.05 was considered to be statistically significant. Results: In our study, maximum patients were from the age group of 36-40 years (51 {32.48%} followed by 31-35 years (38 {24.2%} whereas the least number of patients (6 {3.8%} belonged to the age group of 51-55 years. Uterine fibroids was the most common etiology for menorrhagia seen in 76 (48.4% patients with maximum cases (24 {31.6%} being in 36-40 years age group and minimum (4 {5.3%} in 51-55 years age group. Dysfunctional uterine bleeding (24{15.3%} was the second most common etiology with 6 (25% cases being in 31-35 years age group. No statistically significant association was observed between BMI and etiology of menorrhagia. Backache, abdominal distension, pain abdomen, breast pain, headache, weakness and pelvic pressure were the seven most common symptoms experienced by patients with menorrhagia. All the seven symptoms showed statistically significant association with menorrhagia (p<0.05. Conclusion: Menorrhagia is most prevalent among the age group of 31-35 and 36-40 years with uterine fibroids and dysfunctional uterine bleeding being the most common etiologic factors. There seems to be no clear association of menorrhagia with BMI.

    The purpose of this study was to compare and correlate sagittal condylar guidance determined by intraoral gothic arch tracing method and panoramic radiograph in edentulous patients. Twelve completely edentulous patients were selected by the inclusion and exclusion criteria. Conventional steps in the fabrication of complete denture till jaw relation were carried out. Intraoral gothic arch tracing and protrusive interocclusal records were obtained for each patient. Protrusive interocclusal record was used to program the Hanau Wide-Vue semi-adjustable articulator, thus obtaining the sagittal condylar guidance angle. Using RadiAnt DICOM software, on the orthopantomogram obtained for each patient in the study, two reference lines were drawn. The Frankfort's horizontal plane and the mean curvature line (joining the most superior and the inferior points on the glenoid fossa curvature) were drawn. The mean curvature line was extended to intersect the Frankfort's horizontal plane, thus obtaining the radiographic sagittal condylar guidance angle. The condylar guidance angles obtained by these two methods were compared and subjected to paired t -test. There was no statistically significant difference between the sagittal condylar guidance angles obtained between right and left sides with intraoral gothic arch tracing and radiographic methods ( P = 0.107 and 0.07, respectively). Within the limitations of this study, it was concluded that the protrusive condylar guidance angles obtained by panoramic radiograph may be used for programming semi-adjustable articulators.

    Full Text Available Background: Due to changing lifestyle in Indian population prevalence of hypertension is increasing which needs modification in dietary and exercise habit of the general population. Objective: A study was designed to correlate dietary and exercise habits with hypertension in general population. Material and methods: Present study is a community based cross sectional study among persons aged more than 45 years in Agra district using PPS multi stage simple random sampling technique with a sample size of 553, which includes 260 persons from urban and 293 persons from rural area. Results: Out of 544 persons studied, overall prevalence of hypertension was found to be 36.21% which was 41.47% in urban and 31.47% in rural areas. Prevalence decreases significantly in person engaged in heavy physical activity (14.54%. Hypertension is more prevalent in non vegetarian diet (44.26% as compared to vegetarian (33.88% and very high in population consuming extra salt (73.77%. Conclusion: Prevalence of hypertension in this study is 36.21% and increases with lack of exercise and yoga, non vegetarian diet and consumption of extra salt in diet.

  13. Causal nature of neighborhood deprivation on individual risk of coronary heart disease or ischemic stroke: A prospective national Swedish co-relative control study in men and women.

    We studied the association between neighborhood socioeconomic status (SES) and incidence of coronary heart disease (CHD) or ischemic stroke in the total population and in full- and half-siblings to determine whether these associations are causal or a result from familial confounding. Data were retrieved from nationwide Swedish registers containing individual clinical data linked to neighborhood of residence. After adjustment for individual SES, the association between neighborhood SES and CHD showed no decrease with increasing genetic resemblance, particularly in women. This indicates that the association between neighborhood SES and CHD incidence is partially causal among women, which represents a novel finding. Copyright © 2018 Elsevier Ltd. All rights reserved.

    This thesis reports an light particle interferometric study carried out for the first time by means of an 4{pi} detector. This enabled to extract the proton and deuteron emission time for correctly selected sources. These measurements are extremely worth in the study of hot nuclear matter, particularly for its decaying modes. In this way a clear image of the production chronology of light particles in the heavy ion collision is obtained. In addition, it was possible to make evident the production of fast unstable fragments associated to the decay through pre-equilibrium particles contributing to the very low relative momentum correlation function. This work is the result of a successful event: the association of the 4{pi} INDRA multidetector to the analysis function of the light particle correlation. The real breakthrough achieved by this study was to demonstrate the possibility of full phase space exploration by building the light particle 4 {pi} correlation. In the case of the Xe + Sn system at 45 MeV/u we were able to characterize the collision violence and and to isolate three sources of particle emission. Thus, it was possible to characterize the proton and deuterons emission time for the quasi-target as well as for the quasi-projectile. An important decrease in the characteristic deuteron emission time was observed according as the central collision was approached. Other important results were obtained concerning the proton-proton and proton-deuteron correlation functions as well as the presence of an independent particle dynamical emission of mid-rapidity quasi-targets and quasi- projectiles. Finally, the observation of correlation functions allowed to demonstrate structures at very low relative momentum which can not be understood by the final state interaction only. An explanation could be obtained by a theoretical code taking into account the reaction dynamics, the particle interaction in the final state and the decay of primary excited fragments 74 refs.

    Full Text Available This study aimed to evaluate correlations between carcass and ultrasound measurements of steers finished in pasture. Twelve steers, Nellore e F1 Brangus x Nellore, averaging 22 months old and 464 kg of body weight were used. Longissimus muscle area (LMA and subcutaneous backfat thickness (SBT measured by ultrasound at the day before slaughter and in the carcass were measured. The perimeter (REP, depth (RED and width (REW of LMA in the carcass were measured. Significant correlation of 0.47 and 0.64 for REA and SBT, respectively were detected between the ultrasound and carcass measurements. A positive and significant correlation of 0.93 and 0.70 was obtained for REP and REW, respectively, both with carcass LMA. Ultrasound measurements are correlated to carcass measurements of steers finished in pasture. Longissimus muscle area perimeter and width are high correlated to the area and can be used to estimate LMA.Objetivou-se correlacionar medidas tomadas na carcaça e ultrassônicas em novilhos terminados em pastagem.

    Airborne Ce, Th and Cd in the occupational settings were studied at the monazite mineral beneficiation and zinc ore concentrate processing using nuclear and related analytical techniques. Air samples were collected using grab and size selective samplers simultaneously. The size selective sampler consisted of 8-stage Anderson cascade impactor with back-up filter. Size characterisation showed that the Mass Median Aerodynamic Diameter (MMAD) of the airborne dust at the monazite mineral beneficiation ranged from 3 to 10 {mu}m. The Activity Median Aerodynamic Diameter (AMAD) for Th and Ce were also in the same range. Over 85% of the airborne dust associated with zinc concentrate ore handling was above 9 {mu}m however: the MMAD at the down stream processing was about 3 {mu}m. Composite air samples were subjected to leaching in simulated lung serum to find the solubility class. The urine samples of occupational workers engaged in mineral beneficiation showed Th levels ranging from 39 to 552 ng l{sup -1} with a geometric mean of 186 ng l{sup -1}. The results were obtained using Neutron Activation Analysis (NAA). The observed levels of Th in the urine samples were lower than the predicted levels, due to resistance of the mineral to biochemical leaching. In a limited number of urine samples Ce ranged from 312 to 1587 ng l{sup -1} with a geometric mean of 700 ngl{sup -1}. These values, also determined by NAA, are unique in occupational settings. The Ce to Th ratio in the samples works out to 3.7 as against their ratio of 2.9 in the monazite mineral. The biological levels of Th and Ce observed in occupational settings need refinement on account of the possible environmental contribution due to uptake of these elements in the natural high radiation background areas. Detailed work on characterisation of dust, simulated leaching and analysis of biological samples is in progress in connection with the CRP. (author) 19 refs, 7 figs, 6 tabs

    Full Text Available Thermal and kinetic analyses of the structural changes for the amorphous alloy Fe89.8Ni1.5Si5.2B3C0.5, during the processes of non-isothermal heating and isothermal annealing, have been performed. The crystallisation process has been investigated using the method of differential scanning calorimetry (DSC. It is determined that this alloy crystalizes through three different stages. Changes in the electronic structure of the amorphous tape, for the temperature range 20 to 700ºC have been studied. This was achieved by measuring the thermoelectromotive force (TEMS, of the thermo pair made of two tapes with same chemical structure of the alloy FeNiSiBC, but different atomic structure: one is in the crystal state (CL and the other is in the amorphous state (AM. Analysis of the temperature dependence of the electromotive force has shown the following: the investigated alloy is thermically stable up to 450ºC and changes in the atomic structure as well as equalising of the free electron density in both parts of the thermo pair AM-CL, take place in the temperature range from 450 to 550ºC. Kinetic parameters of the process were determined by measuring time dependence of the TEMS in isothermic conditions at the temperatures 450, 480 and 510ºC.

  20. Corelation among clinical, biochemical and tomographic criteria in order to evaluate the severity in acute pancreatitis Correlación entre criterios clínicos, bioquímicos y tomográficos para evaluar la gravedad de la pancreatitis aguda

    Directory of Open Access Journals (Sweden)

    L. A. Lujano-Nicolás

    2010-06-01

    Full Text Available Background: the acute pancreatitis is an inflammatory process that may involve peripancreatic tissue and distant organs. According to the Atlanta criteria, in 10 to 20% of the patients the disease is severe. Nowadays there are different clinical and biochemical severity scales such as the Ranson, APACHE-II (Acute Physiology and Chronic Health Evaluation and hematocrit, which have discrepancies when being compared to tomographic scales such as the Balthazar. There exist few studies that correlate these parameters. Objective: to evaluate the severity of the acute pancreatitis according to the Ranson, APACHE-II and serous hematocrit criteria at the moment of admission of the patient and correlate these scales with the local pancreatic complications according to the Balthazar classification. Patients and method: retrospective, observational and analytic study. There were included patients of any gender above the age of 18, with diagnosis of acute pancreatitis of any etiology, who had performed an abdominal tomography 72 hours after the beginning of the clinical condition in order to stage the pancreatic damage. The diagnosis of acute pancreatitis was established with 2 of the 3 following criteria: a characteristic abdominal pain; b uprising of the amylase and/or lipase more than 3 times above the superior normal limit; and c characteristic finds of acute pancreatitis in the computed tomography. In order to make the correlation, the Pearson or the Spearman tests were used according to the distribution of the variables. Results: there were included 28 patients (21 masculine, 75%. The most frequent etiology was due to alcohol (53.6%, bile (21.4% and hypertriglyceridemia (17.9%. The age average was 38.1 years old. Fifty per cent of the patients had acute severe pancreatitis according to the Atlanta criteria. Of the patients with APACHE-II less than 8 points, 62.5% were classified according to the Balthazar tomographic scale as D or E degree. Ninety-two point nine per cent of the patients had less than 3 Ranson criteria of which 57.6% got D or E degree. Fifty-seven per cent of the patients with hematocrit value lower than 44% got D and E Balthazar degree, and 64.2% of the patients with hematocrit above 44% got D and E degree. The Pearson correlation (PC for APACHE-II and Ranson p = 0.013 of 0.476 PC for APACHE-II and Balthazar p = 0.367 of 0.476 and Spearman´s correlation p = 0.460 PC for APACHE-II and hematocrit p = 1.32 of 0.476. Conclusions: there does not exist a good correlation between the seriousness scale of Ranson and APACHE-II with the tomographic Balthazar degrees, therefore it is more likely to find very ill patients with an A or B Balthazar and on the other hand patients with acute low pancreatitis with a D or E Balthazar.Antecedentes: la pancreatitis aguda es un proceso inflamatorio que puede involucrar tejido peripancreático y órganos distantes. En 10 a 20% de los pacientes la enfermedad es severa, según criterios de Atlanta. En la actualidad existen diferentes escalas clínicas y bioquímicas de severidad como la de Ranson, APACHE-II (Acute Physiology and Chronic Health Evaluation y hematocrito, las cuales tienen discrepancias al compararlas con escalas tomográficas como la de Balthazar. Existen pocos estudios que correlacionen estos parámetros. Objetivo: evaluar el grado de severidad de la pancreatitis aguda según criterios de Ranson, APACHE-II y hematocrito sérico al ingreso y correlacionar estas escalas con las complicaciones locales pancreáticas según la clasificación de Balthazar. Pacientes y método: estudio retrospectivo, observacional y analítico. Se incluyeron pacientes mayores de 18 años de cualquier género, con diagnóstico de pancreatitis aguda de cualquier etiología, a los que se les realizó tomografía abdominal 72 horas posterior al inicio del cuadro clínico para estadificar el daño pancreático. El diagnóstico de pancreatitis aguda se estableció con 2 de 3 de los siguientes criterios: a dolor abdominal característico; b elevación de amilasa y/o lipasa a más de 3 veces por arriba del límite superior normal; y c hallazgos característicos de pancreatitis aguda en la tomografía computada. Para correlación se utilizó la prueba de Pearson o la de Spearman según la distribución de las variables. Resultados: se incluyeron 28 pacientes (21 masculinos, 75%. La etiología más frecuente fue por alcohol (53,6%, biliar (21,4% e hipertrigliceridemia (17,9%. El promedio de edad fue de 38,1 años. El 50% de los pacientes cursaron con pancreatitis aguda severa según criterios de Atlanta. De los pacientes con APACHE-II menor a 8 puntos, el 62,5% según la escala tomográfica de Balthazar fueron clasificados como grado D o E. El 92,9% de los pacientes tuvieron menos de 3 criterios de Ranson de los cuales el 57,6% obtuvieron grado D o E. El 57% de los pacientes con valor de hematocrito menor a 44% obtuvieron grado D y E de Balthazar, y 64,2% de los pacientes con hematocrito mayor a 44%, obtuvieron grado D y E. La correlación de Pearson (CP para APACHE-II y Ranson p = 0,013 DE 0,476. CP para APACHE-II y Balthazar p = 0,367 DE 0,476 y correlación de Spearman’s p = 0,460. CP para APACHE-II y hematocrito p = 1,32 DE 0,476. Conclusiones: no existe una buena correlación entre la escala de gravedad de Ranson y APACHE-II con los grados tomográficos de Balthazar, por lo cual es probable encontrar pacientes muy graves con un Balthazar A o B y en forma contraria pacientes con pancreatitis aguda leve con Balthazar D o E.

  17. Animal Detection in Natural Images: Effects of Color and Image Database

    Science.gov (United States)

    Zhu, Weina; Drewes, Jan; Gegenfurtner, Karl R.

    2013-01-01

    The visual system has a remarkable ability to extract categorical information from complex natural scenes. In order to elucidate the role of low-level image features for the recognition of objects in natural scenes, we recorded saccadic eye movements and event-related potentials (ERPs) in two experiments, in which human subjects had to detect animals in previously unseen natural images. We used a new natural image database (ANID) that is free of some of the potential artifacts that have plagued the widely used COREL images. Color and grayscale images picked from the ANID and COREL databases were used. In all experiments, color images induced a greater N1 EEG component at earlier time points than grayscale images. We suggest that this influence of color in animal detection may be masked by later processes when measuring reation times. The ERP results of go/nogo and forced choice tasks were similar to those reported earlier. The non-animal stimuli induced bigger N1 than animal stimuli both in the COREL and ANID databases. This result indicates ultra-fast processing of animal images is possible irrespective of the particular database. With the ANID images, the difference between color and grayscale images is more pronounced than with the COREL images. The earlier use of the COREL images might have led to an underestimation of the contribution of color. Therefore, we conclude that the ANID image database is better suited for the investigation of the processing of natural scenes than other databases commonly used. PMID:24130744

  19. A Novel Image Retrieval Based on Visual Words Integration of SIFT and SURF.

    Directory of Open Access Journals (Sweden)

    Nouman Ali

    Full Text Available With the recent evolution of technology, the number of image archives has increased exponentially. In Content-Based Image Retrieval (CBIR, high-level visual information is represented in the form of low-level features. The semantic gap between the low-level features and the high-level image concepts is an open research problem. In this paper, we present a novel visual words integration of Scale Invariant Feature Transform (SIFT and Speeded-Up Robust Features (SURF. The two local features representations are selected for image retrieval because SIFT is more robust to the change in scale and rotation, while SURF is robust to changes in illumination. The visual words integration of SIFT and SURF adds the robustness of both features to image retrieval. The qualitative and quantitative comparisons conducted on Corel-1000, Corel-1500, Corel-2000, Oliva and Torralba and Ground Truth image benchmarks demonstrate the effectiveness of the proposed visual words integration.

  19. Image retrieval by information fusion based on scalable vocabulary tree and robust Hausdorff distance

    Science.gov (United States)

    Che, Chang; Yu, Xiaoyang; Sun, Xiaoming; Yu, Boyang

    2017-12-01

    In recent years, Scalable Vocabulary Tree (SVT) has been shown to be effective in image retrieval. However, for general images where the foreground is the object to be recognized while the background is cluttered, the performance of the current SVT framework is restricted. In this paper, a new image retrieval framework that incorporates a robust distance metric and information fusion is proposed, which improves the retrieval performance relative to the baseline SVT approach. First, the visual words that represent the background are diminished by using a robust Hausdorff distance between different images. Second, image matching results based on three image signature representations are fused, which enhances the retrieval precision. We conducted intensive experiments on small-scale to large-scale image datasets: Corel-9, Corel-48, and PKU-198, where the proposed Hausdorff metric and information fusion outperforms the state-of-the-art methods by about 13, 15, and 15%, respectively.

    India has been the focus of many health surveys among normal, physically, and mentally handicapped children. However, the data, concerning oral health conditions of socially handicapped children living in orphanages, are scanty. To study the effect of parental inadequacy, environmental deprivation, and emotional disturbances on dental caries through intelligence quotient (IQ) and self-concept in orphan children and also to co-relate dental caries with different levels of IQ and self-concept. The study was carried out amongst socially handicapped children living in orphanages. 100 children in the age group of 10-14 years from orphanages were selected. Malin's Intelligence Scale for Indian Children (MISIC) was used to assess the intelligence quotient; self-concept questionnaire to assess self-concept of the child and recording of dental caries status of children was done as per WHO Index (1997). To assess the relationship of dental caries with IQ, student's unpaired t-test was used and; to find the relationship between self-concept and dental caries, Karl-Pearson's coefficient of co-relation was applied. the children in orphanages had a lower IQ and high caries experience but had an above average self-concept. There was also no co-relation between dental caries and self-concept. Orphan children, being socially handicapped, are at an increased risk for dental caries due to a lower IQ level, parental deprivation, and institutionalization. Moreover, lack of co-relation between dental caries and self-concept could be explained by the fact that dental caries is a lifelong process whereas different dimensions of self-concept are in a state of constant flux.

    Coronal mass ejections (CMEs} are the most energetic solar events in which large amount of solar plasma materials are ejected from the sun into heliosphere, causing major disturbances in solar wind plasma, Interplanetary shocks, Forbush decrease(Fds) in cosmic ray intensity and geomagnetic storms. We have studied Forbush decreases associated with intense geomagnetic storms observed at Oulu super neutron monitor, during the period of May 1998-Dec 2006 with coronal mass ejections (CMEs), X-ray solar flares and interplanetary shocks. We have found that all the (100%) Forbush decreases associated with intense geomagnetic storms are associated with halo and partial halo coronal mass ejections (CMEs). The association rate between halo and partial halo coronal mass ejections are found 96.00%and 04.00% respectively. Most of the Forbush decreases associated with intense geomagnetic storms (96.29%) are associated with X-ray solar flares of different categories . The association rates for X-Class, M-Class, and C- Class X -ray solar flares are found 34.62%, 50.00% and 15.38% respectively .Further we have concluded that majority of the Forbush decrease associated with intense geomagnetic storms are related to interplanetary shocks (92.30 %) and the related shocks are forward shocks. We have found positive co-relation with co-relation co-efficient .7025 between magnitudes of Forbush decreases associated with intense geomagnetic storms and speed of associated coronal mass ejections. Positive co-relation with co-relation co-efficient 0.48 has also been found between magnitudes of intense geomagnetic storms and speed of associated coronal mass ejections.

  13. A novel model for Time-Series Data Clustering Based on piecewise SVD and BIRCH for Stock Data Analysis on Hadoop Platform

    Directory of Open Access Journals (Sweden)

    Ibgtc Bowala

    2017-06-01

    Full Text Available With the rapid growth of financial markets, analyzers are paying more attention on predictions. Stock data are time series data, with huge amounts. Feasible solution for handling the increasing amount of data is to use a cluster for parallel processing, and Hadoop parallel computing platform is a typical representative. There are various statistical models for forecasting time series data, but accurate clusters are a pre-requirement. Clustering analysis for time series data is one of the main methods for mining time series data for many other analysis processes. However, general clustering algorithms cannot perform clustering for time series data because series data has a special structure and a high dimensionality has highly co-related values due to high noise level. A novel model for time series clustering is presented using BIRCH, based on piecewise SVD, leading to a novel dimension reduction approach. Highly co-related features are handled using SVD with a novel approach for dimensionality reduction in order to keep co-related behavior optimal and then use BIRCH for clustering. The algorithm is a novel model that can handle massive time series data. Finally, this new model is successfully applied to real stock time series data of Yahoo finance with satisfactory results.

    Homogeneity Index (HI) is an objective tool to analyze the uniformity of dose distribution in the target volume. Various formulae have been described in literature for its calculation but there is paucity of data regarding the ideal formula and the factors affecting this index. This study was undertaken to analyze HI in our patients using various formulae and to find out the co-relation between HI and prescribed dose, target volume and target location. A retrospective review of 99 patients was performed. HI was calculated using five different formulae (A-E). The patients were divided in five groups each, based on prescribed dose, target volume and target location and mean HI of each group was analysed to find the co-relation between these factors and HI. When there were multiple target volumes the primary target volume was studied. The statistical calculation was done using SPSS version 16.0. Ninety nine patients were found evaluable with 75 males and 24 females. Ninety five patients were treated with radical intent and four with palliative intent. The sites treated were head and neck (46.4%), Pelvis (17.1%), brain (15.1%), abdomen (12.1%), and thorax (6.1%). The mean prescribed dose was 4304 cGy (centiGray) and the mean target volume was 476.2 cc. The mean value of HI was 1.21, 2.08, 30.13, 21.51 and 1.27 with different formulae. There was considerable agreement between HI calculated using various formulae specially the formulae considering prescribed dose (C, D). On statistical analysis, there was no significant co-relation between the location and volume of target but there was a trend toward better HI with increasing prescribed dose. Future studies with more number of patients can confirm our results. (author)

    Full Text Available An informal sector in any economy provides different kinds of employment opportunities to people. In Mumbai Metropolitan Region, the female are more involved in regular jobs as compare to the causal and self-employed workers. The secondary and college studied male and female are found more in regular jobs. The high school studied male and illiterate female are working on causal jobs. The causal jobs do not require more education and skills. In self-employed category, the secondary school studied male and high school studied female are found more. The monthly income of workers involved in regular jobs is much higher than the causal and self-employed workers. The moderate malnourished females are found more as compare to the male in causal and self-employed category. The multi nominal logit regression model shows that the causal workers have positive correlation with illiterate male but it is negatively co-related with high school studied male, illiterate and secondary studied female. The monthly income, source of water, refrigerator and condom use is negatively co-related with causal workers as compare to regular workers. The self-employed workers have negative co-relation with monthly wage, source of water and watch cinema regularly as compare to the regular workers. Therefore government must provide infrastructural facilities in all slums of region. The infrastructural facilities such as water supply, electricity, sewage and solid waste collection must be provided in all slums of region. Causal workers must be provided the vocational training to start their own business. Commercial and co-operative banks must provide loans to poor people of slums. Females must be encouraged to take loan and start small business. Government must provide low cost housing to causal and self-employed workers in region. Such policies will certainly improve standard of living of informal sector workers in region.

    1995-01-01

    Previous observations have shown that the solar wind is decelerated and deflected in the earth's upstream region populated by long-period waves. This deceleration is corelated with the 'diffuse' but not with the 'reflected' ion population. The speed of the solar wind may decrease tens of km/s in the foreshock region. The solar wind dynamic pressure exerted on the magnetopause may vary due to the fluctuation of the solar wind speed and density in the foreshock region. In this study, we examine this solar wind deceleration and determine how the solar wind deceleration varies in the foreshock region.

    The concentration of uranium in drinking water sources is a matter of health concern since it has been proved to be chemo-toxic to humans. Uranium being a more soluble actinide is also very mobile in the environment. The effect of water quality parameters and their co-relation to uranium content in the water is an interesting study to understand and predict its behavior in ground water and subsequently to judge the hazard posed. Hence studies on spatial and temporal variation of uranium concentration with electrical conductivity, pH, total dissolved solids and salinity in ground water was carried out. (author)

    The design and construction of repositories for toxic waste, such as radioactive waste of medium and high activity, require tools, that will enable us to predict how the system will behave. The rational behind this Dissertation is based precisely on developing numerical models to study and predict coupled thermal, mechanical, hydrodynamic and geochemical behavior of clays intended to be used as engineered barriers in radioactive waste repository. In order to meet the requirements of the FEBEX Project (Full Scale Engineered Barriers Experiment) it was necessary to develop thermo-hydro-geochemical conceptual and numerical models (THG). For this purpose a THG code was developed to simulate and predict the THG behavior of the clay barrier. The code was created after considering two options. (a) The development of a completely new code, or (b) the coupling of existing codes. In this Dissertation we chose the second option, and developed a new program (FADES-CORE), which was obtained by using the FADES thermo-hydro-mechanical code (Navarro, 1997) and the CORE-LE code (Samper et al., 1998). This process entailed the modification of FADES, the addition of new subroutines for the calculation of solute transport, the modification of CORE-LE and the introduction of additional geochemical and transport processes.

    Full Text Available The machine beaded appearance coincides with the first sewing machine mechanical America sold out in the best-known company of sewing machines in the world: The singer Company in the year 1863. The first machine beaded computer-assisted has been constructed by Wilcom in 1980. After 1990, developments in microprocessors allowed that all types of mechanical machines beaded to turn to digital machines beaded. These machines use digital designs. Developments in digital beaded machines allowed customization industrial products made in series. The raw material that is most important is a digital drawing. List of most important brands is high. Taking into account the number of large editors for embroidery it is almost impossible for a designer to know CAD design for all text editors. This is a problem both for designers but also for producers. A practical solution for designers is CorelDrawings what offers the convenience of design specific vector graphic-designers. Automatic conversion of the vector, the library with textures, simulate embroideries and save specific formats great brands make CorelDrawings a practical alternative. Designer can focus on specific problems without using a large number of editors for each brand. We approached a drawing of the logo to demonstrate practical capabilities. Drawing digital was saved in a format and open industrial professional editor Wilcom Designer. Export to grid format may allow analysis and discussions with the customer before it has been transposed into production.

    A fractal analysis is presented for the binding and dissociation of different heart-related compounds in solution to receptors immobilized on biosensor surfaces. The data analyzed include LCAT (lecithin cholesterol acyl transferase) concentrations in solution to egg-white apoA-I rHDL immobilized on a biosensor chip surface.1 Single- and dual- fractal models were employed to fit the data. Values of the binding and the dissociation rate coefficient(s), affinity values, and the fractal dimensions were obtained from the regression analysis provided by Corel Quattro Pro 8.0 (Corel Corporation Limited).2 The binding rate coefficients are quite sensitive to the degree of heterogeneity on the sensor chip surface. Predictive equations are developed for the binding rate coefficient as a function of the degree of heterogeneity present on the sensor chip surface and on the LCAT concentration in solution, and for the affinity as a function of the ratio of fractal dimensions present in the binding and the dissociation phases. The analysis presented provided physical insights into these analyte-receptor reactions occurring on different biosensor surfaces.

    In December 2014, the largest carbon monoxide (CO) poisoning in Wisconsin's history occurred at an ice arena. Following this event, the Wisconsin Environmental Public Health Tracking (WI EPHT) Program sought to improve outreach and surveillance efforts. WI EPHT designed and distributed educational materials on CO poisoning prevention and surveyed stakeholders to gauge the effectiveness of outreach efforts. To enhance surveillance, WI EPHT utilized data from the Wisconsin Poison Center (WPC) to generate real-time alerts of anomalous numbers of CO-related calls. WI EPHT found that 42% of stakeholders reviewed the outreach materials, and 1 ice arena had installed a CO detector as a result. CO alerts were developed using WPC data and are now routinely used in statewide public health surveillance. WI EPHT staff improved CO poisoning prevention outreach and saw a positive response among stakeholders. This work demonstrates ways that health agencies can improve outreach and surveillance for CO poisoning. Improvements in these areas can bolster public health response and may prevent CO-related illness and injury.

    The aim of this study was to assess the cleaning capacity of the Protaper system using motor-driven or manual instrumentation. Ten mandibular molars were randomly separated into 2 groups (n = 5) according to the type of instrumentation performed, as follows: Group 1 - instrumentation with rotary nickel-titanium (Ni-Ti) files using ProTaper Universal System (Dentsply/Maillefer); and, Group 2 - instrumentation with Ni-Ti hand files using ProTaper Universal (Dentsply-Maillefer). Afterwards, the teeth were sectioned transversely and submitted to histotechnical processing to obtain histological sections for microscopic evaluation. The images were analyzed by the Corel Photo-Paint X5 program (Corel Corporation) using an integration grid superimposed on the image. Statistical analysis (U-Mann-Whitney - P < 0.05) demonstrated that G1 presented higher cleaning capacity when compared to G2. The rotary technique presented better cleaning results in the apical third of the root canal system when compared to the manual technique.

    The design and construction of repositories for toxic waste, such as radioactive waste of medium and high activity, require tools, that will enable us to predict how the system will behave. The rational behind this Dissertation is based precisely on developing numerical models to study and predict coupled thermal, mechanical, hydrodynamic and geochemical behavior of clays intended to be used as engineered barriers in radioactive waste repository. In order to meet the requirements of the FEBEX Project (Full Scale Engineered Barriers Experiment) it was necessary to develop thermo-hydro-geochemical conceptual and numerical models (THG). For this purpose a THG code was developed to simulate and predict the THG behavior of the clay barrier. The code was created after considering two options. a) The development of a completely new code, or b) the coupling of existing codes. In this Dissertation we chose the second option, and developed a new program (FADES-CORE), which was obtained by using the FADES thermo-hydro-mechanical code (Navarro, 1997) and the CORE-LE code (Samper et al., 1998). This process entailed the modification of FADES, the addition of new subroutines for the calculation of solute transport, the modification of CORE-LE and the introduction of additional geochemical and transport processes.

    Full Text Available Ruta graveolens L. is a medicinal plant used in traditional systems of medicine for treatment of psoriasis, vitiligo, leucoderma, and lymphomas with well-known anti-inflammatory and anticancer properties. Therefore antioxidant potential of R. graveolens (in planta and in vitro was investigated. As antioxidants present in plant extracts are multifunctional, their activity and mechanism depends on the composition and conditions of the test system. Therefore, the total antioxidant capacity was evaluated using assays that detect different antioxidants: free radical scavenging (DPPH and ABTS, transition metal ion reduction (phosphomolybdenum assay, reducing power, and nitric oxide reduction. Content of furanocoumarin-bergapten in the extracts showed good corelation with free radical scavenging, transition metal reduction and reducing power, while total phenolic content showed good corelation with nitric oxide reduction potential. Antioxidant activity of in vitro cultures was significantly higher compared to in vivo plant material. The present study is the first report on comprehensive study of antioxidant activity of R. graveolens and its in vitro cultures.

    Monoamine oxidases (MAO) are mitochondrial enzymes functioning in oxidative metabolism of monoamines. The action of MAO-A has been typically described in neuro-pharmacological domains. Here, we have established a co-relation between IL-6/IL-6R and MAO-A and their regulation in hypoxia induced invasion/angiogenesis. We employed various in-vitro and in-vivo techniques and clinical samples. We studied a co-relation among MAO-A and IL-6/IL-6R and tumour angiogenesis/invasion in hypoxic environment in breast cancer model. Activation of IL-6/IL-6R and its downstream was found in hypoxic cancer cells. This elevation of IL-6/IL-6R caused sustained inhibition of MAO-A in hypoxic environment. Inhibition of IL-6R signalling or IL-6R siRNA increased MAO-A activity and inhibited tumour angiogenesis and invasion significantly in different models. Further, elevation of MAO-A with 5-azacytidine (5-Aza) modulated IL-6 mediated angiogenesis and invasive signatures including VEGF, MMPs and EMT in hypoxic breast cancer. High grade invasive ductal carcinoma (IDC) clinical specimen displayed elevated level of IL-6R and depleted MAO-A expression. Expression of VEGF and HIF-1α was unregulated and loss of E-Cadherin was observed in high grade IDC tissue specimen. Suppression of MAO-A by IL-6/IL-6R activation promotes tumour angiogenesis and invasion in hypoxic breast cancer environment.

    Full Text Available The representation weft knitted fabrics covers a wide range of methods, which may vary from country to country or may be similar, being used identical or slightly modified. In Romania, currently, for the weft knitted fabrics are used four methods of representing the knitted structures, namely: structural or analytical representation, representation using knitting notations, symbolic representation of the section of stitch courses and representation of drawing design. Generalization of knitted fabrics design using CAD systems determined the development of software design, including 2D representation that can be used for any type of machine. 2D representation of stitches solves the modeling problems and is possible to be executed using different computer graphics programs (CorelDRAW, AUTOCAD, etc. With the help of the graphic editor CORELDRAW it is possible to make the graphical representation of the structure of any kind of weft knitted fabric regardless of its complexity, strating from the simplest ones such as knits with basic weaves (single jersey, rib fabric, links, links and links patterns to the most complex structures such as knitted fabrics with different evolutionary changes of normal stitches (tuck loop knits, missed stitches knits, racked stitches knits, etc. or those with combined designs (knitted jacquard, intarsia knits etc.. This paper presents the possibility of using the CorelDRAW application for representing knitted structures.

  6. Nonfatal, unintentional, non--fire-related carbon monoxide exposures--United States, 2004-2006.

    Carbon monoxide (CO) is a colorless, odorless, nonirritating gas that is produced through the incomplete combustion of hydrocarbons. Sources of CO include combustion devices (e.g., boilers and furnaces), motor-vehicle exhaust, generators and other gasoline or diesel-powered engines, gas space heaters, woodstoves, gas stoves, fireplaces, tobacco smoke, and various occupational sources. CO poisoning is a leading cause of unintentional poisoning deaths in the United States; it was responsible for approximately 450 deaths each year during 1999-2004 and an estimated 15,200 emergency department (ED) visits each year during 2001-2003. Health effects of CO exposure can range from viral-like symptoms (e.g., fatigue, dizziness, headache, confusion, and nausea) to more severe conditions (e.g., disorientation, unconsciousness, long-term neurologic disabilities, coma, cardiorespiratory failure, and death). CO poisoning often is misdiagnosed and underdetected because of the nonspecific nature of symptoms. To update a previously published report and provide national estimates of CO-related ED visits during 2004-2006, CDC analyzed data from the National Electronic Injury Surveillance System--All Injury Program (NEISS-AIP) database. During 2004-2006, an estimated average of 20,636 ED visits for nonfatal, unintentional, non-fire-related CO exposures occurred each year. Approximately 73% of these exposures occurred in homes, and 41% occurred during winter months (December-February). Prevention efforts targeting residential and seasonal CO exposures can substantially reduce CO-related morbidity.

    Prevotella intermedia/nigrescens is one of the well-known pathogens causing periodontal diseases, and the red florescence excited by the visible blue light caused by the protoporphyrin IX in the bacterial cells could be useful for the chair-side detection. The aim of this study was to evaluated levels of periodontal pathogen, especially P. intermedia in clinical samples of red fluorescent dental plaque. Thirty two supra gingival plaque samples from six individuals were measured its fluorescence at 640nm wavelength excited by 409nm. Periodontopathic bacteria were counted by the Invader PLUS PCR assay. Co-relations the fluorescence intensity and bacterial counts were analyzed by Person's correlation coefficient and simple and multiple regression analysis. Positive and negative predictive values of the fluorescence intensities for with or without P. intermedia in supragingival plaque was calculated. When relative fluorescence unit (RFU) were logarithmic transformed, statistically significant linear relations between RFU and bacterial counts were obtained for P. intermedia, Porphyromonas gingivalis and Tannerella forsythia. By the multiple regression analysis, only P. intermedia had statistically significant co-relation with fluorescence intensities. All of the fluorescent dental plaque contained P. intermedia m. In contrast, 28% of non-fluorescent plaques contained P. intermedia. To check the fluorescence dental plaque in the oral cavity could be the simple chair-side screening of the mature dental plaque before examining the periodontal pathogens especially P. intermedia by the PCR method.

    Vidarbha region in Maharashtra, India is witnessing a continuous decrease in orange crop due to the propagation of `Phytopthora root rot', a water mold disease. Under favorable conditions, the disease causing bacteria can attack the plant root system and propagates to the surface (where first visual impression is made), making difficult to regain the plant health. This research aims at co-relating eco-hydrological fluxes with disease sensing parameters of orange trees. Two experimental plots around a healthy-young and declined-young orange trees were selected for our analysis. A 3-dimentional electrical resistivity tomography (ERT) (Figure) was carried at each plot to quantify the soil moisture distribution at a vadose zone. Pedo-electric relations were obtained considering modified Archie's law parameters. ERT derived moisture data was validated with time domain reflectometry (TDR) point observations. Soil moisture profiles derived from ERT were observed to be differ marginally between the two plots. Disease quantification was done by estimating the density of Phytopthora spp. inoculum in soils sampled along the root zone. Identification of Phytopthora spp. was done in the laboratory using taxonomic and morphologic criteria of the colonies. Spatio-temporal profiles of soil moisture and inoculum density were then co-related to comment on the eco-hydrological fluxes contributing to the health propagation of root rot in orange tree for implementing effective water management practices.

    The extreme floods in northern parts of Pakistan are caused by glacier lake outbursts and Dam-Breaks following landslides, which block river valleys. Geographically glacier dams in mountain rivers and valleys have occurred from the east-western and west-western Karakuram ranges and in the lesser Karakuram range floods which arise from Karakuram precipitation and temperature of various region pose greater problem, as these floods are neither homogeneous nor stationary. These floods arise from various generating mechanisms i. e. generated by melting of snow and glacier and those generated from the monsoon rainfall and dam-breaks following landslide into the river and out burst of glacier lake. The estimation of present and future risk of flooding at sites in northern Pakistan requires an understanding, of the climate, which provides, the generating mechanism of floods. Climates are extremely variable and depend op broad global circulation patterns and local topographic influences. The variables of the climate are studied using available data, with emphasis on temperature and precipitation Spatial Co-relation in northern area stations have been conducted to find Co-relation Co-efficient, using regression analysis. This is spread over intra seasonal and inter station comparison. The time series analysis of the climatic variables has been conducted to examine geographically and statistically the trend in their behaviour. This may be reflected in the hydrological regime of glaciers and rivers and it can cause non linear flood series through changes in any one of the flood generating mechanism. The climate feed-back mechanism has been discussed, which are practically important because they assist seasonal prediction of climate and flow in the Indus. Additionally if climate warming is causing an upward Trend in winter and spring temperature and reduction in snowfall, the effect might be felt more widely over the region.

    A mobile phone, also known as cell phone or hand phone, is among the most popular electrical devices used by people all over the world. The present study examines the vibration perception of mobile phones by co-relating the relevant design parameters such as excitation frequency, and size and mass of mobile phones to the vibration perception survey by volunteers. Five popular commercially available mobile phone models were tested. The main findings for the perception surveys were that higher vibration frequency and amplitude of the peak acceleration would result in stronger vibration perception of the mobile phones. A larger contact surface area with the palms and figures, higher peak acceleration and the associated larger peak inertia force may be the main factors for the relatively higher vibration perception. The future design for the vibration alert of the mobile phones is likely to follow this trend. Copyright © 2013 Elsevier Ltd and The Ergonomics Society. All rights reserved.

    Full Text Available Knowledge of maize germplasm genetic diversity is important for planning breeding programmes, germplasm conservation per se etc. Genetic variability of maize hybrids grown in the fields is also very important because genetic uniformity implies risks of genetic vulnerability to stress factors and can cause great losts in yield. Early maturing maize hybrids are characterized by shorter vegetation period and they are grown in areas with shorter vegetation season. Because of different climatic conditions in these areas lines and hybrids are developed with different features in respect to drought resistance and disease resistance. The objective of our study was to characterize set of early maturing maize hybrids with protein and RAPD markers and to compare this clasification with their pedigree information. RAPD markers gave significantly higher rate of polymorphism than protein markers. Better corelation was found among pedigree information and protein markers.

    Solanum is one of the largest and hyper diverse genera of the family Solanaceae. In Pakistan Solanum is represented by 15 species, of which 11 species have the medicinal properties. Taxonomically this is a complex genus because of the presence of number of hybrid and controversial taxonomic status of S. nigrum complex. In the present study numerical techniques were utilized to evaluate the taxonomic status of the genus Solanum. Cluster analysis was employed to work out the relationship among the taxa of the genus Solanum. The Euclidean distance measured similarity matrix and a dendrogram was constructed by using the complete linkage method. This analysis showed that all the species of genus Solanum can easily be divided into two groups at hundred percentage linkage distance. Co-relation of quantitative characters showed that floral characters had highly significant relationship with the stem characters, these characters plays a significant role in the identification of the species of the genus Solanum.

    Full Text Available A primordial aspect of the Sartrian critique of alienation concerns understanding the analytic ideology as the domination of materiality over the symbolic, in other words as the reification of the human, and therefore as anticulture. In the context of contemporary nihilism, the decoding of the mechanisms which consign praxis to the practico-inert requires a critique of the relations between the social sciences and philosophy, which in its turn implies a new theory of the relation between what Sartre calls the "notion" (the area of subjectivity and the "concept" (objectivity, From this perspective, the deconstruction of the established frontiers between the social sciences and philosophy, and between the conceptual and the narrative, is corelative to a redefinition of the relation between theory and practice.

    Romantic love is a "universal... or near universal" human phenomenon. Recently, love, romantic love, also became a theme of interest for scientists. The current research is seeking an explanation to clarify the brain mechanisms that are responsible for love behavior and feelings. Until recently, the study of love has been mainly the field of psychology. The biology of love originates in the primitive parts of brain that eolved long before the cerebral cortex. Discoveries in neuroscience have led to the identification of specific areas, facilities, brain circuits that are involved in the genesis of love. However, love remained a research field mainly for psychologists, despite the massive increase in neuroscientific research. In the last few decades, there has been a significant increase in the number of studies on the neuronal corelates of love, through the use of neuroimaging techniques (fMRI, PET) and in the studies that have investigated the action of the neurotransmitter and neuroendocrine systems.

    In this paper we have searched for the existence of Lyra’s cosmology in a hybrid universe with minimal interaction between dark energy and normal matter using Bianchi-V space-time. To derive the exact solution, the average scale factor is taken as a={({t}n{e}kt)}\\frac{1{m}} which describes the hybrid nature of the scale factor and generates a model of the transitioning universe from the early deceleration phase to the present acceleration phase. The quintessence model makes the matter content of the derived universe remarkably able to satisfy the null, dominant and strong energy condition. It has been found that the time varying displacement β(t) co-relates with the nature of cosmological constant Λ(t). We also discuss some physical and geometrical features of the universe.

    A reduction of computing effort was achieved as a result of the application of space - independent continuous slowing down theory in the spectrum averaged cross sections and further expressing then in a quadratic corelation whith the temperature and the composition. The decoupling between variables that express some of the important nuclear characteristics allowed to introduce a sensitivity analyses treatment for the full prediction of the behavior, over the fuel cycle, of the LMFBR considered. As a potential application of the method here in developed is to predict the nuclear characteristics of another reactor, face some reference reactor of the family considered. Excellent agreement with exact calculation is observed only when perturbations occur in nuclear data and/or fuel isotopic characteristics, but fair results are obtained whith variations in system components other than the fuel.

    The objectives were to determine the variability and to compare the genetic diversity obtained using amplified fragment length polymorphism (AFLP) markers in analyses of wine, tequila, mezcal, sotol and raicilla yeasts. A molecular characterization of yeasts isolated from Mexican agave musts, has been performed by AFLP marker analysis, using reference wine strains from Italian and South African regions. A direct co-relation between genetic profile, origin and fermentation process of strains was found especially in strains isolated from agave must. In addition, unique molecular markers were obtained for all the strains using six combination primers, confirming the discriminatory power of AFLP markers. This is the first report of molecular characterization between yeasts isolated from different Mexican traditional agave-distilled beverages, which shows high genetic differences with respect to wine strains.

    Differentiation of obstructed from dilated, nonobstructed urinary systems in the postoperative child is a difficult diagnostic problem. A comparison study was performed in 21 children with hydroureteronephrosis using the Whitaker test in combination with conventional radionuclide renography and/or diuretic (furosemide)-augmented radionuclide renography. The results of each method were corelated with the clinical assessment and surgical findings. Conventional renography was found to be an unreliable study, with a clinical correctness of only 57%. Results were more favorable for both the Whitaker test and diurectic-augmented radionuclide renography, with clinical correctness in 86% and 85%, respectively. Due to the noninvasive nature of the study, diuretic-augmented radionuclide renography should be the initial procedure once hydroureteronephrosis is established. A recommended algorithm of the child with postoperative hydroureteronephrosis is suggested

    Mortensen, Jonathan; Wu, Jia Jie; Furst, Jacob; Rogers, John; Raicu, Daniela

    Normalized Information Distance, based on Kolmogorov complexity, is an emerging metric for image similarity. It is approximated by the Normalized Compression Distance (NCD) which generates the relative distance between two strings by using standard compression algorithms to compare linear strings of information. This relative distance quantifies the degree of similarity between the two objects. NCD has been shown to measure similarity effectively on information which is already a string: genomic string comparisons have created accurate phylogeny trees and NCD has also been used to classify music. Currently, to find a similarity measure using NCD for images, the images must first be linearized into a string, and then compared. To understand how linearization of a 2D image affects the similarity measure, we perform four types of linearization on a subset of the Corel image database and compare each for a variety of image transformations. Our experiment shows that different linearization techniques produce statistically significant differences in NCD for identical spatial transformations.

    2005-10-01

    A rigorous theoretical investigation has been made of electro- acoustic [particularly, dust-ion acoustic (DIA) and dust-acoustic (DA)] shock waves in unmagnetized dusty plasmas. The reductive perturbation method has been employed for the study of the small but finite amplitude DIA and DA shock waves. It has been reported that the dust grain charge fluctuation can be one of the candidates for the source of dissipation, and can be responsible for the formation of DIA shock waves in an unmagnetized dusty plasma with static charged dust particles. It has also been reported that the strong co-relation among dust particles can be one of the candidates for the source of dissipation, and can be responsible for the formation of DA shock waves in an unmagnetized strongly coupled dusty plasma. The basic features and the underlying physics of DIA and DA shock waves, which are relevant to space and laboratory dusty plasmas, are briefly discussed. (author)

    Forensic image analysis is required an expertise to interpret the content of an image or the image itself in legal matters. Major sub-disciplines of forensic image analysis with law enforcement applications include photo-grammetry, photographic comparison, content analysis and image authentication. It has wide applications in forensic science range from documenting crime scenes to enhancing faint or indistinct patterns such as partial fingerprints. The process of forensic image analysis can involve several different tasks, regardless of the type of image analysis performed. Through this paper authors have tried to explain these tasks, which are described in to three categories: Image Compression, Image Enhancement & Restoration and Measurement Extraction. With the help of examples like signature comparison, counterfeit currency comparison and foot-wear sole impression using the software Canvas and Corel Draw.

    Full Text Available Contemporary academic debates often deal with the issue of the compatibility of Islam with liberal values. The issues most commonly encountered in these debates are the compatibility of Islam with principles of secularism, democracy and human rights. The definition of human rights in current international documents includes: the position and status of religious minorities, freedom of belief, opinion and expression, the position of women in society, children's rights, the rights of people with disabilities, and many others. This paper will specifically deal with (corelations between Islam and the position of women in society, as well as a theoretical analysis of the most important works of women theorists who have dealt with Islamic feminism and rereading of Qur'an from a woman's perspective. Also, once the work has given basic assumptions of the most important works of these women theorists, we will offer their critical review.

  5. Formation of nanostructures on HOPG surface in presence of surfactant atom during low energy ion irradiation

    2016-07-15

    Low energy ions beam often develop periodic patterns on surfaces under normal or off-normal incidence. Formation of such periodic patterns depends on the substrate material, the ion beam parameters, and the processing conditions. Processing conditions introduce unwanted contaminant atoms, which also play strong role in pattern formation by changing the effective sputtering yield of the material. In this work we have analysed the effect of Cu, Fe and Al impurities introduced during low energy Ar{sup +} ion irradiation on HOPG substrate. It is observed that by changing the species of foreign atoms the surface topography changes drastically. The observed surface topography is co-related with the modified sputtering yield of HOPG. Presence of Cu and Fe amplify the effective sputtering yield of HOPG, so that the required threshold for the pattern formation is achieved with the given fluence, whereas Al does not lead to any significant change in the effective yield and hence no pattern formation occurs.

    2005-01-01

    Regular and extensive social population mobility in natural economy is neither necessary nor possible while in a planned economic system, social population distribution is necessary but social population mobility is unlikely. Modern market economy as a highly mobile economy has a free-mobile population characteristic of market economy, which is fundamental to optimize human resource distribution. The rule for the modern market-based population movement is as follows: If the mobile population is the rational behavior choosers, under the permissive developmental environment as arranged by the social system, they tend to move from low profit-making fields to high income fields when there exists comparable difference of income in different regions and different industries, and various potential and practical profit-making chances. The degree of difference in comparable income is positively co-relative to the velocity and flux of mobile population.

    Full Text Available While it is well known that space environment can produce spacecraft anomaly, defining space environment effects for each anomalies is difficult. This is caused by the fact that spacecraft anomaly shows various symptoms and reproducing it is impossible. In this study, we try to find the conditions of when spacecraft failures happen more frequently and give satellite operators useful information. Especially, our study focuses on the geosynchronous satellites which cost is high and required high reliability. We used satellite anomaly data given by Satellite News Digest which is internet newspaper providing space industry news. In our analysis, 88 anomaly cases occurred from 1997 to 2008 shows bad corelation with Kp index. Satellite malfunctions were likely to happen in spring and fall and in local time from midnight to dawn. In addition, we found the probability of anomaly increase when high energy electron flux is high. This is more clearly appeared in solar minimum than maximum period.

    Thermal fatigue events, which may cause shutdown of nuclear power stations by wall-through-crack of pipes of RCRB (Reactor Coolant Pressure Boundary), are reported by licensees in foreign countries as well as in Japan. In this paper, thermal fatigue events reported in anomalies reports of light water reactors inside and outside of Japan are investigated. As a result, it is clarified that the thermal fatigue events can be classified in seven patterns by their characteristics, and the trend of the occurrence of the events in PWRs (Pressurized Water Reactors) has stronger co-relation to operation hours than that in BWRs (Boiling Water Reactors). Also, it is concluded that precise identification of locations where thermal fatigue occurs and its monitoring are important to prevent the thermal fatigue events by aging or miss modification.

    Anecdotal evidence suggests that there are high rates of smoking among Burmese men in Wollongong, Australia. A qualitative study was undertaken to explore the beliefs and experiences of Burmese refugees in Wollongong on smoking to guide the development of smoking cessation interventions. Three focus groups were conducted with Burmese refugees. Ten semi-structured interviews were conducted with service providers involved with Burmese refugees. Qualitative content analysis was used to categorise responses to the questions. Participants were aware of the health effects of tobacco smoking but had little knowledge of support for quitting. Many participants chewed betel quid and were unaware of the health consequences. Service providers noted the lack of resources on smoking and betel quid use for Burmese people. Smoking cessation interventions for Burmese people should consider the co-related use of betel quid due to the possibility of inadvertently encouraging use of betel nut as an alternative to tobacco.

    Abstract: In the post-communist era, the contemporary national Eastern Orthodox churches have often been accused of taking either direct or ideological part in violence across Eastern Europe. In several scholarly analyses, the churches have been linked with ethnic and national violence. They have...... thus been identified as an ideological root for a distinctive ethno-religious nationalism either blocking the way for a pluralistic society or simply defying it. These cases of violence and conflicts, as well as their subsequent analysis, only point to a practical and visible manifestation of conflicts......, and they therefore don’t answer a broader theological question, namely the question of the general position of the Eastern Orthodox churches regarding violence. This article will address this broader question of what the Orthodox churches’ position is on violence and discuss the co-relation and intersection between...

    2010-12-01

    Full Text Available Purpose: Activities in the manufacturing sector are often considered the bedrock of an economy and a key driver of growth and development. Within the South African manufacturing sector, operations skills are reported to be deficient and are often cited as a main cause of failure in small, medium and micro enterprises (SMMEs. This study explores and tests this fragile relationship between operations skills and SMME sustainability. Empirical investigations are conducted in a high-density SMME manufacturing environment - the Vaal Triangle Region. Design/Methodology/Approach: Building on previously established literature on SMME sustainability and operations skills, various measures are developed and tested for reliability and validity. Factor analysis is used to identify relevant factors in terms of operations skills. Co-relational analysis is then employed to test the hypothesised relationship. The study is cross-sectional in design and relies on trained fieldworkers administering surveys for data collection. Findings: Five clear factors for operations skills are identified through factor analysis with an overall high reliability value. Based on descriptive and co-relational analysis results reveal that operations skills are positively associated with sustainability. Implications: SMME owners, educators and service providers may benefit from the study's findings in terms of the nature and associations that operational skills have on developing sustainable SMME's. Originality/Value: The study focused on a neglected area of SMMEs - the importance of operations towards business sustainability, and made an important contribution towards theory development through empirical explorations. In South Africa, this is the first time an instrument measuring operations skills has been validated and associated with SMMEs in a manufacturing context.

    Hippo pathway target, YAP has emerged as an important player in solid tumor progression. Here, we identify RUNX1 and RUNX3 as novel negative regulators of oncogenic function of YAP in the context of breast cancer. RUNX proteins are one of the first transcription factors identified to interact with YAP. RUNX1 or RUNX3 expression abrogates YAP-mediated pro-tumorigenic properties of mammary epithelial cell lines in an interaction dependent manner. RUNX1 and RUNX3 inhibit YAP-mediated migration and stem-ness properties of mammary epithelial cell lines by co-regulating YAP-mediated gene expression. Analysis of whole genome expression profiles of breast cancer samples revealed significant co-relation between YAP–RUNX1/RUNX3 expression levels and survival outcomes of breast cancer patients. High RUNX1/RUNX3 expression proved protective towards YAP-dependent patient survival outcomes. High YAP in breast cancer patients’ expression profiles co-related with EMT and stem-ness gene signature enrichment. High RUNX1/RUNX3 expression along with high YAP reflected lower enrichment of EMT and stem-ness signatures. This antagonistic activity of RUNX1 and RUNX3 towards oncogenic function of YAP identified in mammary epithelial cells as well as in breast cancer expression profiles gives a novel mechanistic insight into oncogene–tumor suppressor interplay in the context of breast cancer progression. The novel interplay between YAP, RUNX1 and RUNX3 and its significance in breast cancer progression can serve as a prognostic tool to predict cancer recurrence. PMID:29581836

    The Co-doped ZnO microwires (MWs) were grown using the optical furnace method. We used Scanning electron microscopy (SEM), polarized micro-Raman spectroscopy, photoluminescence (PL) and optical absorption spectroscopy to systematic investigation of the optical and structural properties of Co-doped ZnO MWs. The SEM analysis reveals that Co-doped ZnO MWs has hexagonal facets and cavity inside. The EDS results confirmed the presence and non-uniform distribution of Co impurities in the samples. Co doping of ZnO MWs leads to the decreased intensity, drastically broadening and high-energy shift of the NBE PL band. The red emission band at 1.85 eV originates from 2E(2G) → 4A2 (4F) intra-3d-transition of Co2+ in the ZnO lattice has been observed. The intense structured absorption bands within the near infrared ranges 3800-4800 and 5500-9000 cm-1 are caused by electronic spin-allowed transitions 4T2(F) ← 4A2(F) and 4T1(F) ← 4A2(F) of the tetrahedrally coordinated Co2+ (3 d7) ions substituting Zn2+ ions in Co-doped ZnO MWs. Micro-Raman studies of Co doped ZnO MWs show doping/disorder induced additional modes as compared to the undoped sample. The resonant enhancement of the additional local Co-related A1-symmetry Raman mode is observed in the parallel polarization geometry y(z , z) ybar . For the Co doped ZnO MWs, the enhancement of the additional Co-related local vibration mode with an increase in the excitation photon energy is also observed in the Raman spectra.

    2014-01-01

    Coronal Mass Ejections (CMEs) are the drastic solar events in which huge amount of solar plasma materials are ejected into the heliosphere from the sun and are mainly responsible to generate large disturbances in solar wind plasma parameters and geomagnetic storms in geomagnetic field. We have studied geomagnetic storms, (Dst ≤-75 nT) observed during the period of 1997-2007 with Coronal Mass Ejections and disturbances in solar wind plasma parameters (solar wind temperature, velocity, density and interplanetary magnetic field) .We have inferred that most of the geomagnetic storms are associated with halo and partial halo Coronal Mass Ejections (CMEs).The association rate of halo and partial halo coronal mass ejections are found 72.37 % and 27.63 % respectively. Further we have concluded that geomagnetic storms are closely associated with the disturbances in solar wind plasma parameters. We have determined positive co-relation between magnitudes of geomagnetic storms and magnitude of jump in solar wind plasma temperature, jump in solar wind plasma density, jump in solar wind plasma velocity and jump in average interplanetary magnetic field with co-relation co-efficient 0 .35 between magnitude of geomagnetic storms and magnitude of jump in solar wind plasma temperature, 0.19 between magnitude of geomagnetic storms and magnitude of jump in solar wind density, 0.34 between magnitude of geomagnetic storms and magnitude of jump in solar wind plasma velocity, 0.66 between magnitude of geomagnetic storms and magnitude of jump in average interplanetary magnetic field respectively. We have concluded that geomagnetic storms are mainly caused by Coronal Mass Ejections and disturbances in solar wind plasma parameters that they generate.

    Over the last few decades, because of the significant development of anion exchange membranes, increasing efforts have been devoted the realization of anion exchange membrane fuel cells (AEMFCs) that operate with the supply of hydrogen generated on-site. In this paper, ammonia was selected as a hydrogen source, following which the effect of conceivable impurities, unreacted NH 3 and atmospheric CO 2 , on the performance of AEMFCs was established. As expected, we show that these impurities worsen the performance of AEMFCs significantly. Furthermore, with the help of in situ attenuated total reflection infrared (ATR-IR) spectroscopy, it was revealed that the degradation of the cell performance was primarily due to the inhibition of the hydrogen oxidation reaction (HOR). This is attributed to the active site occupation by CO-related adspecies derived from (bi)carbonate adspecies. Interestingly, this degradation in the HOR activity is suppressed in the presence of both NH 3 and HCO 3 - because of the bicarbonate ion consumption reaction induced by the existence of NH 3 . Further analysis using in situ ATR-IR and electrochemical methods revealed that the poisonous CO-related adspecies were completely removed under NH 3 -HCO 3 - conditions, accompanied by the improvement in HOR activity. Finally, a fuel cell test was conducted by using the practical AEMFC with the supply of NH 3 -contained H 2 gas to the anode and ambient air to the cathode. The result confirmed the validity of this positive effect of NH 3 -HCO 3 - coexistence on CO 2 -tolerence of AEMFCs. The cell performance achieved nearly 95% of that without any impurity in the fuels. These results clearly show the impact of the chemically induced bicarbonate ion consumption reaction on the realization of highly CO 2 -tolerent AEMFCs.

  20. IQ and schizophrenia in a Swedish national sample: their causal relationship and the interaction of IQ with genetic risk.

    2015-03-01

    The authors sought to clarify the relationship between IQ and subsequent risk for schizophrenia. IQ was assessed at ages 18-20 in 1,204,983 Swedish males born between 1951 and 1975. Schizophrenia was assessed by hospital diagnosis through 2010. Cox proportional hazards models were used to investigate future risk for schizophrenia in individuals as a function of their IQ score, and then stratified models using pairs of relatives were used to adjust for familial cluster. Finally, regression models were used to examine the interaction between IQ and genetic liability on risk for schizophrenia. IQ had a monotonic relationship with schizophrenia risk across the IQ range, with a mean increase in risk of 3.8% per 1-point decrease in IQ; this association was stronger in the lower than the higher IQ range. Co-relative control analyses showed a similar association between IQ and schizophrenia in the general population and in cousin, half-sibling, and full-sibling pairs. A robust interaction was seen between genetic liability to schizophrenia and IQ in predicting schizophrenia risk. Genetic susceptibility for schizophrenia had a much stronger impact on risk of illness for those with low than high intelligence. The IQ-genetic liability interaction arose largely from IQ differences between close relatives. IQ assessed in late adolescence is a robust risk factor for subsequent onset of schizophrenia. This association is not the result of a declining IQ associated with insidious onset. In this large, representative sample, we found no evidence for a link between genius and schizophrenia. Co-relative control analyses showed that the association between lower IQ and schizophrenia is not the result of shared familial risk factors and may be causal. The strongest effect was seen with IQ differences within families. High intelligence substantially attenuates the impact of genetic liability on the risk for schizophrenia.

    Graphical abstract: Crystallite size of tetragonal phase of the zirconia samples prepared using different synthesis parameters and precursors as a function of calcination temperature. Surface area values of the zirconia samples calcined at 500 and 700 °C are in given brackets. - Highlights: • Zirconia prepared with modified sol–gel method is less stable compared with zirconia prepared by precipitation method. • Optimized synthesis conditions shifted the glow exotherm to higher temperature range indicating better thermal stability. • Tetragonal-zirconia could be synthesized in cost-effective manner using zirconium oxy-nitrate. • In our studies no co-relation between the surface area and crystallite size was observed. - Abstract: Under identical and judiciously pre-optimized synthesis conditions, the influence of different combinations of zirconium sources and/or post treatment conditions on structural properties, thermal stability, phase composition and morphology of zirconia has been investigated. High surface area tetragonal zirconia could be synthesized in a cost-effective manner from 1 M solution of zirconium oxy-nitrate at pH 11 using aqueous ammonia solution as a precipitant when calcined at 400 °C for 3 h. Irrespective of the preparation method, pH and starting precursor, zirconia samples prepared without digestion contained dominant monoclinic phase with some traces of tetragonal phase when calcined at 700 °C. Even though there is linear decrease in surface area with increase in the crystallite size for each sample as a function of calcination temperature, no co-relation between the surface area and crystallite size could be achieved. SEM images show agglomerated and irregular shape particles between 10 to 20 μm.

EMI CT 5005 whole body scanner was used to obtain scan of the liver and spleen, and CT number of them was measured in EMI units, so L/S ratio was calculated by dividing both EMI number. In the patients with obesity, the EMI number of the liver and/or spleen were higher than normal controls. In acute hepatitis, EMI number of the liver, spleen and L/S ratio were no significant differences compared with controls. In chronic hepatitis inactive and active type, EMI number of the liver and spleen were no significant differences between chronic hepatitis and controls, but L/S ratio was lower than that of controls. In cirrhosis of the liver, EMI number of the liver and L/S ratio were lower than that of controls, but EMI number of the spleen had no significant differences compared with controls. In patients with fatty liver, EMI number of the liver and L/S ratio were lower than any other diffuse liver diseases. In alcoholic liver injury had no significant differences from normal controls in liver EMI number, spleen EMI number and L/S ratio. In intrahepatic cholestsis, there was weak inverse corelation between liver EMI number and serum total bilirubin, and in obstructive jaundice strong inverse corelation was seen. In diffuse liver diseases, fatty infiltration, liver cell necrosis, fibrosis or jaundice may decrease the EMI number of the liver and/or L/S ratio, but except for fatty liver, it seems difficult to diagnose the diffuse liver diseases by CT scanner.

    Future growth in dental practice lies in digital imaging enhancing many chairside procedures and functions. This revolution requires the fast, accurate, and 3D digitizing of clinical records. One such clinical record is the chairside impression. This study investigated how surface angle and surface roughness affect the digitizing of vinyl polysiloxane impression materials. Seventeen vinyl polysiloxane impression materials were digitized with a white light optical digitizing system. Each sample was digitized at 3 different angles: 0 degrees, 22.5 degrees, and 45 degrees, and 2 digitizer camera f-stops. The digitized images were rendered on a computer monitor using custom software developed under NIH/NIDCR grant DE12225. All the 3D images were rotated to the 0 degrees position, cropped using Corel Photo-Paint 8 (Corel Corp, Ottawa, Ontario, Canada), then saved in the TIFF file format. The impression material area that was successfully digitized was calculated as a percentage of the total sample area, using Optimas 5.22 image processing software (Media Cybernetics, LP, Silver Spring, MD). The dependent variable was a Performance Value calculated for each material by averaging the percentage of area that digitized over the 3 angles. New samples with smooth and rough surfaces were made using the 7 impression materials with the largest Performance Values. These samples were tested as before, but with the additional angle of 60 degrees. Silky-Rock die stone (Whip Mix Corp, Louisville, KY) was used as a control. The Performance Values for the 17 impression materials ranged from 0% to 100%. The Performance Values for the 7 best materials were equivalent to the control at f/11 out to a surface angle of 45 degrees; however, only Examix impression material (GC America Inc, Alsip, IL) was equivalent to the control at f/11/\\16. At the 60 degrees surface angle with f/11/\\16, the Performance Values were 0% for all the impression materials, whereas that for the control was 90

  5. Liturgy and Morality. Constitution  on the Sacred Liturgy Sacrosanctum Concilium in the Context of Moral Theology

    Full Text Available The fiftieth anniversary of the promulgation of the Constitution on the Sacred Liturgy of Vaticanum II encourages attempts of its interpretation in the context of moral theology. It leads to the conclusion that there is a co-relation between liturgy and morality in the history of salvation. The Revelation of the Old Testament reveals the conjunction between worship and morality. Attempts to separate the two in the history of the Chosen People raise objections of prophets. Their criticism, however, comes together with the announcement of the future in which God will reveal the divisions between worship and morality. The New Testament shows the fulfilment of this promise in Jesus Christ. His salvific work establishes the Christian liturgy, in which man participates as a physical, as well as a spiritual being. The salvation, made present in the liturgy of the Church, is a relation, the co-operation of God and man, grace and freedom. Sacrosantum Concilium presents this revealed truth, emphasising the objective and subjective dimensions of liturgy as the work of Christ, in which a Christian participates actively, freely and consciously (participatio actuosa. The participation is mostly spiritual, therefore moral at the same time. Only than can the external elements of liturgy take place, including its detailed forms, gestures, attitudes and behaviours of the sacred liturgy participants. It means that the liturgical participatio actuosa requires moral works through imitation of Christ leading to conversion. That is when “faith works through love” (cf. Gal 5 : 6. It leads us to the notion of sacrifice, which, as far as man is concerned, requires a total change. Sinful man presented with the love of the Triune God may respond to it with his own, gradually maturing love. The process constitutes the drama of God and man, which is the tension between grace and freedom, which is then represented by the co-relation between liturgy and morality

    Full Text Available Purpose: There are increasing reports on failure of clinical response to ciprofloxacin in typhoid fever despite the strain being sensitive to drug in in-vitro using standard guidelines and showing mutations in DNA gyrase. But this increased MIC and clinical failures with ciprofloxacin are not always co-related with mutations presently identified in gyrA and parC genes. This shows that there may be other mechanisms such as an active drug efflux pump responsible as has been shown in other Enterobacteriaceae. This study was carried out to determine the role of efflux pump in Salmonella Typhi isolates. Materials and Methods : Total 25 already characterized nalidixic acid sensitive and nalidixic acid resistant S. Typhi strains with different range of ciprofloxacin MIC were included to study the role of efflux pump in the presence of CCCP (efflux pump inhibitor. For genotypic characterization, the entire acrR gene was sequenced to confirm the presence of any mutation in the gene. Results: The MIC of ciprofloxacin remained same in the presence and absence of CCCP in the studied strains and no significant mutations were found in the acrR gene in any of the isolates studied. Conclusions: No role of efflux pump in ciprofloxacin resistance was found in strains studied. There is a need to explore further mechanism of ciprofloxacin resistance in Salmonella Typhi.

    Full Text Available Lactic acid bacterias (LAB: Streptococcus thermophilus-ST, Lactobacillus bulgaricus-LB are well known in the food technology area for their ability to produce lactic acid (LA from carbohydrates throught fermentation. In case of goji yogurt the interaction between the two species of LAB has influence on the fermentation period and LA quantity. LAB’s are widely used in the food industry because their growth in the dairy products lowers the carbohydrate content, they can also drop the pH values under 4.0, values were common pathogens are inhibited, and because of all these properties they are capable to prolong the shelf life. The present study aims to observe the evolution of LAB’s – ST and LB, from goji yogurt (7% (A and goji yogurt (7% with honey (B during the shelf life in corelation with other physico-chemical properties such as sugar content, fat content and dry matter. The samples for the evaluation were taken in the first day of storage, at the middle of storage period and in the last day of storage.

    To determine the prevalence of oral mucosal lesions (OMLs) and denture-related mucosal lesions (DMLs) in denture wearers and to co-relate the prevalence with age, gender, type of denture and any systemic conditions. Dental records of 380 denture wearers were retrospectively reviewed for OMLs and DMLs. We found 45% of the denture wearers had DMLs and 60.8% had OMLs not related to denture wearing. Although the prevalence of DMLs was higher in complete denture wearers than in partial denture wearers (49% vs. 42.2%), this difference was not significant. The most common DMLs were traumatic ulcer (19.5%) and denture-induced stomatitis (18.1%). When analysed by type, traumatic ulcer, denture hyperplasia, frictional keratosis and candidiasis were more common in complete denture wearers, whereas denture-induced stomatitis was more common in partial denture wearers. Frictional keratosis was more common in men than in women. The prevalence of OMLs not related to denture wearing was higher in complete denture wearers than in partial denture wearers, and the most common OML was fissured tongue (27.6%). No association between DMLs and systemic conditions or xerostomic drugs was noted. No differences in the prevalence of DMLs in association with denture type were found. The prevalence of OMLs not related to denture wearing was higher in complete denture wearers than in partial denture wearers. This difference was affected by age, and the data were similar to the findings observed in the elderly.

    Full Text Available Treatment for Hodgkin′s lymphoma (HL has resulted in excellent survival rates but is associated with increased risks of secondary therapy-related acute myeloid leukemia (t-AML. Gingival enlargement associated with bleeding and ulceration is the most common rapidly appearing oral manifestations of leukemic involvement. An 8 months pregnant patient reported with generalized gingival enlargement, with localized cyanotic and necrotic papillary areas. Co-relating the hematological report with the oral lesions and her past medical history of HL, a diagnosis of t-AML secondary to treatment for HL was made by the oncologist. As oral lesions are one of the initial manifestations of acute leukemia, they may serve as a significant diagnostic indicator for the dental surgeons and their important role in diagnosing and treating such cases. Furthermore, this case report highlights the serious complication of t-AML subsequent to HL treatment and the important role that a general and oral health care professional may play in diagnosing and treating such cases.

    Various machine learning and data mining tasks in classification require abundant data samples to be labeled for training. Conventional active learning methods aim at labeling the most informative samples for alleviating the labor of the user. Many previous studies in active learning select one sample after another in a greedy manner. However, this is not very effective because the classification models has to be retrained for each newly labeled sample. Moreover, many popular active learning approaches utilize the most uncertain samples by leveraging the classification hyperplane of the classifier, which is not appropriate since the classification hyperplane is inaccurate when the training data are small-sized. The problem of insufficient training data in real-world systems limits the potential applications of these approaches. This paper presents a novel method of active learning called manifold regularized experimental design (MRED), which can label multiple informative samples at one time for training. In addition, MRED gives an explicit geometric explanation for the selected samples to be labeled by the user. Different from existing active learning methods, our method avoids the intrinsic problems caused by insufficiently labeled samples in real-world applications. Various experiments on synthetic datasets, the Yale face database and the Corel image database have been carried out to show how MRED outperforms existing methods.

    Full Text Available We have described the conventional and microwave method for the synthesis of N-(4-((2-chloroquinolin-3-ylmethylene-5-oxo-2-phenyl-4,5-dihydro-1H-imidazol-1-yl(arylamides 3a–l. It is observed that the solvent-free microwave thermolysis is a convenient, rapid, high-yielding, and environmental friendly protocol for the synthesis of quinoline based imidazole derivatives when compared with conventional reaction in a solution phase. Antimicrobial activity of the newly synthesized compounds is screened in vitro on the following microbial cultures: Escherichia coli (MTCC 443, Pseudomonas aeruginosa (MTCC 1688, Staphylococcus aureus (MTCC 96, Streptococcus pyogenes (MTCC 442, Candida albicans (MTCC 227, Aspergillus niger (MTCC 282, Aspergillus clavatus (MTCC 1323. All the synthesized bio-active molecules are tested for their in vitro antimicrobial activity by bioassay namely serial broth dilution. Among these compounds 3c, 3d, 3f, 3h and 3j show significant potency against different microbial strains. All the compounds have been characterized by IR, 1H NMR, 13C NMR and mass spectral data. On the basis of statistical analysis, it is observed that these compounds give significant co-relation.

    1986-01-01

    The syndrome of ''subendocardial infarction'' or ''non Q-wave infarction'', which has been defined only in terms of the presence of (ECG) electrocardiographic evidence of necrosis, has been shown to be poorly corelated with anatomical and pathomorphological findings. In a large number of patients who had been diagnosed as having this commonly described entity, the usefulness of a multiparametric approach was evaluated. The proper assessment of such patients may necessitate flow studies with T1-201, which is, however, a marker with known limitations: labelled microspheres; or Rb-82, a generator-produced positron emitter. Metabolic studies using fluoro-F-18-deoxyglucose or C-11 palmitate will defect impairment of fatty acid oxidation and residual glucose metabolism; wall motion studies will demonstrate impairment to a variable extent. The presence or absence of Q-waves does not distinguish between transmural and subendocardial infarction. The size and location of ST-T wave changes does not indicate the site of infarction. Patients with this syndrome exhibit a wide spectrum of wal motion abnormalities and usually have diffuse coronary lesions. Since conventional clinical investigations cannot be used to predict the presence and extent of necrosis, or its exact location, the studies performed should be directed toward the appropriate evaluation of perfusion and metabolic patterns. This emphasizes the important point that clinicians may investigate this syndrome by the use of the proper approach. (orig.)

    Culture develops from a civilization and progresses through the generations in tangible and intangible forms affecting various aspects of living. It gradually becomes a rulebook that guides the way of life for some people. This holds true in the Indian Society, which is punctuated by constant incorporation of migrating people with the diverse cultures that surround India. Such illustrious past should predict augmented conservation efforts. However, that is not the case. Following the Hindu philosophy of the life cycle, buildings are allowed to be deteriorating over the passage of time. It was only much later that the occidental influence of the British Empire encouraged conservation of built heritage. Yet today these efforts are absent at the most basic levels. On one side are the international organizations such as UNESCO providing guidelines for protection of these buildings and the on the other side are the government and non-government organizations which help maintain the structures. Co-relation between the two levels of conservation are non-existent in a way that initiatives by the government focus on improving infrastructure but neglect the Risk-assessment of the buildings. Such examples will be discussed further in the paper with suggestions to improve the situation with the help of new technologies and simplified methods that include making conservation education easier for even the most rural population. The research explores avenues of diagnosis integrated in the Italian philosophy of conservation to make maintenance more easy and effective.

    The structural integrity of dissimilar metal welded (DMW) joint consisting of low-alloy steel and 304LN austenitic stainless steel was examined by evaluating mechanical properties and metallurgical characteristics. INCONEL 82 and 182 were used as buttering and filler materials, respectively. Experimental findings were substantiated through thermomechanical simulation of the weld. During simulation, the effect of thermal state and stress distribution was pondered based on the real-time nuclear power plant environment. The simulation results were co-related with mechanical and microstructural characteristics. Material properties were varied significantly at different fusion boundaries across the weld line and associated with complex microstructure. During in-situ deformation testing in a scanning electron microscope, failure occurred through the buttering material. This indicated that microstructure and material properties synergistically contributed to altering the strength of DMW joints. Simulation results also depicted that the stress was maximum within the buttering material and made its weakest zone across the welded joint during service exposure. Various factors for the failure of dissimilar metal weld were analyzed. It was found that the use of IN 82 alloy as the buttering material provided a significant improvement in the joint strength and became a promising material for the fabrication of DMW joint.

    Full Text Available In this paper are presented the phases for improving from an aesthetic point of view a clothing item, the T-shirt for women using software design patterns, computerised graphics and textile different modern technologies including: industrial embroidery, digital printing, sublimation. In the first phase a documentation was prepared in the University of Oradea and traditional motif was selected from a collection comprising a number of Romanian traditional motifs from different parts of the country and were reintepreted and stylized whilst preserving the symbolism and color range specified to the area. For the styling phase was used CorelDraw vector graphics program that allows changing the shape, size and color of the drawings without affecting the identity of the pattern. The embroidery was done using BERNINA Embroidery Software Designer Plus Software. This software allows you to export the model to any domestic or industrial embroidery machine regardless of brand. Finally we observed the resistance of the printed and embroided model to various: elasticity, resistance to abrasion and a sensory analysis on the preservation of color. After testing we noticed the imprint resistance applied to the fabric, resulting in a quality that makes possible to keep the Romanian traditional motif from generation to generation.

    A Gibbs Sampler based topic model for image annotation, which takes into account the interaction between visual geometric context and related topic, is presented. Most of the existing topic models for scene annotation use segmentation-based algorithm. However, topic models using segmentation algorithm alone sometimes can produce erroneous results when used to annotate real-life scene pictures. Therefore, our algorithm makes use of peaks of image surface instead of segmentation regions. Existing approaches use SIFT algorithm and treat the peaks as round blob features. In this paper, the peaks are treated as anisotropic blob features, which models low level visual elements more precisely. In order to better utilize visual features, our model not only takes into consideration visual codeword, but also considers influence of visual properties to topic formation, such as orientation, width, length and color. The basic idea is based on the assumption that different topics will produce distinct visual appearance, and different visual appearance is helpful to distinguish topics. During the learning stage, each topic will be associated with a set of distributions of visual properties, which depicts appearance of the topic. This paper considers more geometric properties, which will reduce topic uncertainty and learn the images better. Tested with Corel5K, SAIAPR-TC12 and Espgame100k Datasets, our method performs moderately better than some state of the arts methods.

    The purpose of this study was to investigate the reliability of photogrammetry in the measurement of the postural deviations in individuals with idiopathic scoliosis. Twenty participants with scoliosis (17 women and three men), with a mean age of 23.1 ± 9 yrs, were photographed from the posterior and lateral views. The postural aspects were measured with CorelDRAW software. High inter-rater and test-retest reliability indices were found. It was observed that with more severity of scoliosis, greater were the variations between the thoracic kyphosis and lumbar lordosis measures obtained by the same examiner from the left lateral view photographs. A greater body mass index (BMI) was associated with greater variability of the trunk rotation measures obtained by two independent examiners from the right, lateral view (r = 0.656; p = 0.002). The severity of scoliosis was also associated with greater inter-rater variability measures of trunk rotation obtained from the left, lateral view (r = 0.483; p = 0.036). Photogrammetry demonstrated to be a reliable method for the measurement of postural deviations from the posterior and lateral views of individuals with idiopathic scoliosis and could be complementarily employed for the assessment procedures, which could reduce the number of X-rays used for the follow-up assessments of these individuals.

    Objective: To evaluate the intra- and inter-examiner reliability and reproducibility of goniometry in relation to photogrammetry of hand, comparing the angles of thumb abduction, PIP joint flexion of the II finger and MCP joint flexion of the V finger. Methods: The study included 30 volunteers, who were divided into three groups: one group of 10 physiotherapy students, one group of 10 physiotherapists, and a third group of 10 therapists of the hand. Each examiner performed the measurements on the same hand mold, using the goniometer followed by two photogrammetry software programs; CorelDraw® and ALCimagem®. Results: The results revealed that the groups and the methods proposed presented inter-examiner reliability, generally rated as excellent (ICC 0.998 I.C. 95% 0.995 - 0.999). In the intra-examiner evaluation, an excellent level of reliability was found between the three groups. In the comparison between groups for each angle and each method, no significant differences were found between the groups for most of the measurements. Conclusion: Goniometry and photogrammetry are reliable and reproducible methods for evaluating measurements of the hand. However, due to the lack of similar references, detailed studies are needed to define the normal parameters between the methods in the joints of the hand. Level of Evidence II, Diagnostic Study.

    ZnO thin films are deposited on the glass substrates by sol-gel drain coating technique by varying the concentration of the sol. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis were used to investigate the effect of sol concentration on the crystallinity and surface morphology of the films. The results show that with increase in sol concentration, the value of full width at half maximum (FWHM) of (0 0 2) peak decreases while the strain first increases and then decreases. The sol with higher concentration results in the increase in the grain size. The studies on the optical properties show that the band gap value increases from 3.27 to 3.3 eV when the sol concentration changes from 0.03 to 0.1 M. The photoconductivity studies reveal that the film for 0.05 M sol shows the maximum photoresponse for ultraviolet (UV) wavelength (<400 nm) which is co-related with the deep-level defects. The growth and decay of the photocurrent is found to be slowest for the same film

    Carbon monoxide (CO) is an odorless, colorless gas produced by fossil fuel combustion. On October 29, 2012, Hurricane Sandy moved ashore near Atlantic City, New Jersey, causing widespread morbidity and mortality, $30 to $50 billion in economic damage, and 8.5 million households to be without power. The combination of power outages and unusually low temperatures led people to use alternate power sources, placing many at risk for CO exposure. We examined Hurricane Sandy-related CO exposures from multiple perspectives to help identify risk factors and develop strategies to prevent future exposures. This report combined data from 3 separate sources (health departments, poison centers via the National Poison Data System, and state and local public information officers). Results indicated that the number of CO exposures in the wake of Hurricane Sandy was significantly greater than in previous years. The persons affected were mostly females and those in younger age categories and, despite messaging, most CO exposures occurred from improper generator use. Our findings emphasize the continued importance of CO-related communication and ongoing surveillance of CO exposures to support public health response and prevention during and after disasters. Additionally, regional poison centers can be a critical resource for potential on-site management, public health promotion, and disaster-related CO exposure surveillance.

    2017-07-01

    We successfully prepared synthetic nanocomposite (SNC) by dispersing graphene quantum dots (GQD) in cellulose acetate (CA) polymer system. The dispersion and occupied network of GQD were foreseen by microscopic techniques. The variation of plane to crossed linked array network was observed by the polarizing optical microscopic (POM) technique. The scanning electron microscopy (SEM) revealed the leaves like impressions of GQD in host polymer system. The series network of GQD occupied in CA at higher resolution was confirmed by transmission electron microscopy (TEM). The two dimensional (2D) topographic images demonstrated an entangled polymer network to plane morphology. The variation in surface roughness was evaluated from the dimensional (3D) topography. The influence of temperature on AC conductivity with highest value (4  ×  10-5 S cm-1), contributes to the decrease in activation energy. The DC conductivity obeys the percolation criteria co-related to the GQD loading by weight fraction. Furthermore, this synthetic nanocomposite is feasible for the development of sensing and electrical applications.

    Complex resistivity method has become the key technique of deep prospecting, and widely applied in stratabound sulfide deposits which often form massive ores. However, the complex resistivity spectrum characteristics of stratabound sulfide deposits remains unknown. Through studying variation problem of two-dimensional polarization medium, deducing the differential equations and calculating formula,we applied Cole-Cole model to deduce the spectrum of complex resistivity based on the model of three-node and four-node finite element method, and programmed homologous procedure. We utilized the Earth Model of Geological Layers which has accurate analytical solution to test rationality and accuracy of our modeling. We applied the layer structure provided by drilling results in Chenmenshan copper mine,which is typical strata-bound sulfide deposits in Jiangxi province,China, and calculated the spectra of complex resistivity, then made comparison between modeled and measured values. We find good corellation between them. Our studies may have imporved the interpretation of complex resistivity data, which help apply complex resistivity methods of propecting on stratabound sulfide deposites.

    Full Text Available The present paper explains the stages of clothing style improvement by using computer graphics programs. Ovidiu Stan, a student in the Department of Textiles and Leatherworking and Industrial Management, under our guidance, did research at the Ethnographic Museum of Transylvania in Cluj Napoca, where he selected a folk pattern specific to Transylvania area, reinterpreted it and digitized it in the vector graphics program CorelDRAW. This program allows the shape and size of drawings to be modified, and offers a vast chromatic palette which allows us to style the drawings. The pattern was printed on the T-shirt with an Azon Tex Pro printer, which can replace screen-printing or thermal transfer. The printing system is high-speed and very high quality, and the printed patterns can be unique, highly resistent to wear and washing. After the digitization stage, the next stage was to embroider the pattern on the T-shirt with the Happy embroidery machine. The embroidered pattern was designed by using the BERNINA Embroidery Software Designer Plus software. This embroidery software offers the freedom to design and edit elegant monograms, and complete freedom of creative design. All the projects completed with this software can bear their own distinct, individual mark, as an original work of art.

Objectives: Correlative analysis of ABO & Rh system, dietary habits & alcohol consumption with PCOS. Materials & Methods: 100 patients between (20-30 years, diagnosed with PCOS were selected. A standard PCOS questionnaire was given. Blood group & dietary status data were collected. Patients were grouped according to ABO & Rh system considering their diet & alcohol intake (p≤0.05 significant. Result: Our data revealed that the highest risk of PCOS was observed in females with blood group ‘O’ positive followed by ‘B’ positive who were on mixed diet & used to consume alcohol. Our study also suggests that Rh negative individuals didn’t show any association with PCOS. Conclusion: The results of our study suggest that ‘O’ positive females, are more prone to PCOS. Though the relative frequency of B positive individuals are more in India, females with blood group O positive are more susceptible to PCOS, contributing factors being mixed diet & alcohol intake. So, early screening of ‘O’ positive &‘B’ positive females of reproductive age-group in South-India, could be used as a measure for timely diagnosis of PCOS, better management &also prevention of complications. However, further research should be done to investigate the multifaceted mechanisms triggering these effects.

    Alumina, the most versatile and widely used refractory ceramic oxide, has currently occupied the position of the most preferred material in engineering ceramic industry. Though limited to some extent, the experience so far has been that the selection of an inappropriat high alumina ceramic can lead to cost penalties and poor performance in service. With this in view, one of the studies undertaken at the research laboratories of The Associated Cement Cos.Ldt. (India) has been to synthesise alumina powders by various process routes and to compare their physico-mechanical, thermal, textural and microstructural characteristics so as to understand the effects emanating from the powder synthesis processes on the performance properties of alumina. Following this approach, the present paper deals with aluminas obtained from four process routes, viz. Sol-Gel, Controlled Precipitation, Pyrolysis and Aluminium salts and conventional alumina obtained by calcination of gibbsite. The properties of these four varieties of alumina are characterised with respect to chemical analysis, particle size, textural features, grindability, etc. Behaviour of these powders in green processing/shaping particularly in terms of compaction, density, binder requirements, etc. have been studied. The calcination characteristics as reflected in shrinkage, densification and crystal morphology have been examined. Finally, the physical and thermal properties of Aluminas obtained from various synthesis routes and their co-relation with various powder characteristics and compact microstrcture have been dealt with.

    2018-01-01

    The role of d electrons in determining distributions of formation and migration energies for point defects in equiatomic NiCoCr and NiCoFeCr concentrated solid solution alloys (CSAs) are studied regarding electron density deformation flexibility based on first-principles calculations. The disordered state is taken into account by constructing special quasirandom structures. The migration barriers are determined by directly optimizing the saddle point. It is found that the formation energies of interstitials in CSAs are lower than those in pure Ni, whereas the formation energies of vacancies are higher. In both NiCoCr and NiCoFeCr, Co-related dumbbell interstitials exhibit lower formation energies. Notably, the distributions of migration energies for Cr interstitials and vacancies exhibit a remarkable overlap region. A detailed analysis of electronic properties reveals that the electronic charge deformation flexibility regarding eg to t2g transition has a dominant effect on defect energetics for different elements in CSAs. Thus the electron deformation ability is suggested as a key factor in understanding the peculiar defect behavior in CSAs.

    Full Text Available The paper aims to examine taxation in the EU in correlation with regional development measures implemented. We started with the EU vision on regional development. If during the 2007-2013 period, were pursued three major objectives (convergence, regional competitiveness and territorial cooperation, in the current 2014-2020 funding period, money is allocated differently between countries that are deemed to be more developed, in transition and less developed. These categories are set according to GDP per capita. Next we exposed the fiscal changes made in the EU in 2010-2011 period and then we corelate them with the strategy for regional development for five member states: Romania, Bulgaria, Czech Republic , Hungary and Poland. We used data reported by Eurostat regarding the evolution of unemployment rate and for the foreign direct investments in 2007-2012 period. We also brought up and changes required by the new Romanian Fiscal Code. According to it, measures such as reduction of income tax for new micro enterprises or extending the VAT reverse charge mechanism in many sectors of activity, are meant to encourage foreign capital inflows and also to increase the level of regional development. As a general conclusion, we found that there is a direct link between fiscal policy and regional development; fiscal measures implemented influence the level of unemployment, economic growth, and competitiveness in the private sector.

    The molecular structure, vibrational spectra and polarizabilities of Ethyl 4-Dimethylaminobenzoate (EDAB) was investigated by density functional theory employing Becke's three parameter hybrid exchange functional with Lee-Yang-Parr (B3LYP) co-relational functional involving 6-311++G(d,p) basis set and compared with some other levels. A detailed interpretation of the IR and Raman spectra of EDBA have been reported and analyzed. Complete vibrational assignments of the vibrational modes have been done on the basis of the potential energy distribution (TED) using VEDA software. The molecular electrostatic potential mapped onto total density surface has been obtained. A study on the electronic properties, such as absorption wavelength, and frontier molecular orbitals energy, was performed using DFT approach. The stability of the molecule arising from hyper conjugative interactions and accompanying charge delocalization has been analyzed using natural bond orbital (NBO) analysis. The natural and Mulliken charge also calculated and compared with different level of calculation. The dipole moment, polarizability and first, second order hyperpolarizabilities of the title molecule were calculated and compared with the experimental values. The energy gap between frontier orbitals has been used along with electric moments and first order hyperpolarizability, to understand the non linear optical (NLO) activity of the molecule. The NLO activity of molecule was confirmed by SHG analysis.

    The dried alfalfa seeds (12.1% moisture) were exposed to 6 '0Co γ radiation field with 0∼36.1 C/kg radiation doses (irradiation rate is 2.84 x 10 -2 C/(kg·min)) to observe and measure some radio-bio-effectivity. In the range of irradiation doses, vitality index, root length, seedling survival rate, seedling height, plant height and grass yield decreased and pollen sterility, micro-nucleus rate, free radical relative content increased as the amount of radiation increased. The activity of peroxidase increased as the amount of radiation increased within certain range of dose and tended to decreased beyond that range. Vitality index and root length, which dosage effect curve is compatible with multiple targets-single hit model, and seedling survival rate, seedling height, plant height and grass yield, which dosage effect curve is compatible with linear regression model. There were strong co-relations between the seedling height, micro-nucleus cell rate and the free radical relative content (P<0.01). There were very significant difference (P<0.01) between the alfalfa species and varieties. With fuzzy concentration analysis method, the alfalfa sample were classified into five groups: higher sensitive, sensitive, intermediate, resistant, higher resistant. The suitable irradiation doses for the alfalfa species and varieties are between 12.9∼34.8 mCi/kg

    40 normal individuals and 153 patients with lesions in the head and neck were examined by conventional imaging methods and by means of MR angiography (1.5 Tesla Magnetome). The problems to be solved concerned the ralationship between tumors and vessels and vascular anomalies and abnormalities at the skull base (56 cases), the facial skeleton (62 cases) and the neck (35 cases). Digital subtraction angiography was performed in 54 patients and the findings corelated with MR angiography. Optimal results were obtained by using a FISP 3D sequence; in this way arterial structures could be rendered reproducibly down to a diameter of 2 mm. The venous system in the head and neck was best shown by a FLASH 2D sequence. Correlation with arterial DSA showed high accuracy of MR angiography (91%) concerning displacement of vessels, the topography and the recognition of vascular occlusions. Our results indicate that MR angiography is a rapid and reliable procedure for evaluating the arterial and venous changes due to tumors in the head and neck region. (orig.) [de

    Gut microbiome dysbiosis plays a profound role in the pathogenesis of obesity and tributyltin (TBT) has been found as an environmental obesogen. However, whether TBT could disturb gut microbiome and the relationship between obesity induced by TBT exposure and alteration in gut microbiota are still unknown. In order to assess the association between them, mice were exposed to TBTCl (50 μg kg -1 ) once every three days from postnatal days (PNDs) 24 to 54. The results demonstrated that TBT exposure resulted in increased body weight gain, lager visceral fat accumulation and dyslipidemia in male mice on PND 84. Correspondingly, 16S rRNA gene sequencing revealed that TBT treatment decreased gut microbial species and perturbed the microbiome composition in mice. Furthermore, Pearson's corelation coefficient analysis showed a significantly negative correlation between the body weight and the alpha diversity of gut microbiome. These results suggested that TBT exposure could induce gut microbiome dysbiosis in mice, which might contribute to the obesity pathogenesis. Copyright © 2018 Elsevier B.V. All rights reserved.

These compounds were synthesized by gel combustion method followed by heating in reduced atmospheres at 1673 K. To co-relate lattice parameters with metal and oxygen concentrations, reduced oxides were heated in Ar, CO2 and air atmospheres. Retention of FCC phase was confirmed in all mixed oxides with y ≤ 0.4. The cubic lattice parameters could be expressed in a linear equation of x and y as: a (Ǻ) = 5.5709 - 0.187 x + 0.032 y; [x Oxidation studies and simple ionic model calculations suggested that uranium is predominantly present as a mixture of +5 and + 6 states when La/U ratio ∼2. Oxidation kinetics of mixed oxides was studied by non-isothermal method using thermogravimetry and was found to be a diffusion controlled reaction. High temperature X-ray diffraction studies of LUTL and UTL mixed oxides showed positive thermal expansion in the temperature range of 298-1273 K and % expansion increases with La concentration.

    Drug discovery from natural products resources have been extensively studied worldwide because natural products with their great structural diversity have traditionally provided most of the drugs in use. They offer major opportunities for finding novel low molecular weight leading-structures that are active against a wide range of assay targets. The most important step in the discovery process is the identification of compounds with interesting biological activity. Single crystal X-ray structure determination is a powerful technique for natural products research and drug discovery. The detailed three-dimensional structures that emerge can be co-related to the activities to these structures. In this article the following is presented: (i) co-crystal and disorder structures; (ii) determination of absolute configuration and (iii) the ability to distinguish between whether a natural product compound is a natural product or a natural product artifact. All these three properties are unique to the technique of single crystal X-ray structure determination. Case (iii) was demonstrated with a compound containing a chromene ring, namely macluraxanthone (which was isolated from Cratoxylum formosum subsp. pruniflorum, a Thai medicinal plant). (author)

    Full Text Available The introduction of the innovation in business is critical factor of the quality of the accommodation offer and the success of the hotel. Studies have shown that there is a relationship between category and innovativeness of the hotel, where the higher categories hotels have been shown to be more innovative. The aim of this study is to explore the relationship between category and innovativeness of the hotel, as well as to determine the differences in terms of innovation and types of innovation, depending on the category of the hotel. The study included 57 hotels of the first, second and third category in Serbia. The survey was conducted on a sample of 512 employees. The results of correlation analysis showed there is no corelation between the category and innovativeness of the hotel. The results of ANOVA showed that the second category hotels are more innovative than hotels with three and five stars. Statistically significant differences between the first, second and third category were found in the case of process innovation, product and service innovation and management innovation.

    A reliable and economic supply of energy is a must for growth of any civilisation. There exists a strong co-relation between per capita gross domestic product (GDP) and per capita electricity consumption. In fact, during the development of the human civilisation, the per-capita energy consumption of Individual human beings has risen from about 5 gigajoules per year for the primitive man (1,000,000 B.C.) to about 350 gigajoules per year for the modem technological man. A sharp contrast is seen between the developed and developing countries in energy consumptions. About 28% of the world population (mostly comprising of the developed countries) consumes more than 75% of the world energy production while all most of the world population consumes less that 1/4 of the world energy production. A handful of developed countries have per capita electricity consumption of the order of 10,000 kWh per year as compared to the developing countries where this figure is much lower than 1000 kWh. All efforts therefore must he put for improvement in energy intensity to achieve socio-economic growth of the developing countries, so as to provide an equitable standard of living to the citizen of all the countries

    Full tex: Obtaining, exploration and application of amorphous fusions on the basis of iron group magnet metals including amorphous phase non-magnetic additions as silisium and boric playing the role of stabilizer of the amorphous phase is widely used last years. Scientific and technical interest to these objects is connected with their physical property - high mechanical, electric, uncial agreement of corrosion and magnet characteristics. Amorphous alloy Fe58Ni20Si9B13 was selected as the object of research. To set the built-in hysteresis characteristics of magnetic fusion mesh, then the maximum magnetic induction (saturation induction) was appointed to the BS and the residual induction Br. The average distance between the borders as a result of pressure and magnetic characteristics of nano parosities in comparison of the relative change that is to say they are close to each other, with the magnetic characteristics of amorphous fusions nano parosity characteristics indicate that the corellation is between magnetic characteristics and nano parosity characteristics.

    Spiritual well-being is one of the fundamental concepts in chronic diseases which create meaning and purpose in life and is an important approach in promoting general health and quality of life. This study performed to determine the level of spiritual health and its dimensions in patients with multiple sclerosis (MS). 236 members of Iranian MS Society were volunteered to participate in a descriptive co-relational study. Spiritual well-being was evaluated by The Spiritual Well-Being Scale (SWBS) questionnaires in two religious and Existential dimensions. Descriptive statistics, ANOVA, t-test and Pearson correlation coefficient were used to analyse the data. The majority of patients (% 97.9) showed moderate spiritual well-being (mean score = 74.3, SD= 8.90). Although Existential well-being (mean score = 40.3, SD= 5.51) was higher than religious well- being (mean score = 33.9, SD= 4.88). A significant relationship was seen between economic status and the spiritual well-being. The results emphasize on the necessity of spiritual well-being as an effective factor on different aspects of these patients' life. This key point is useful and even necessary to be considered to design programs of care and cure for these patients in a country (like Iran) with cultural and religious beliefs. On the other hand, patients' economic status should be considered.

    Full Text Available Dental caries is a multifactorial disease. The most important factors in the development of caries is saliva. Reduced salivary secretion in patients with type 2 diabetes melitus to the occurrence of caries have yielded controversial results. The aim of the study was to find out whether the risk factors of the saliva i.e. saliva secretion rate, buffer capacity, salivary S. mutans, salivary Lactobacilli, alone or in combination, could be used for prediction of caries activity. Thirty patients with type 2 diabetes mellitus and age range 46-73 participated. Diabetic status was determined by fasting plasma glucose is >126mg/dl, 2-hour plasma glucose is >140mg/dl. Decayed, missing, and filled teeth indices were determined by means of clinical examination. Stimulated saliva with parafin was measured for flow rate and buffer capacity, level of S. mutans & Lactobacilli were analyzed with dentobuff and dentocult. There was no decrease in salivary secretion in patients with type 2 diabetes melitus. Significant corellation were found between buffer capacity, and combination of the S. mutans & Lactobacilli counts in caries activity.

    Full Text Available In order to effectively retrieve a large database of images, a method of creating an image retrieval system CBIR (contentbased image retrieval is applied based on a binary index which aims to describe features of an image object of interest. This index is called the binary signature and builds input data for the problem of matching similar images. To extract the object of interest, we propose an image segmentation method on the basis of low-level visual features including the color and texture of the image. These features are extracted at each block of the image by the discrete wavelet frame transform and the appropriate color space. On the basis of a segmented image, we create a binary signature to describe the location, color and shape of the objects of interest. In order to match similar images, we provide a similarity measure between the images based on binary signatures. Then, we present a CBIR model which combines a signature graph and a self-organizing map to cluster and store similar images. To illustrate the proposed method, experiments on image databases are reported, including COREL,Wang and MSRDI.

    Full Text Available Satellite images are an important source of information to identify and analyse some hazardous climatic phenomena such as the dryness and drought. These phenomena are characterized by scarce rainfall, increased evapotranspiration and high soil moisture deficit. The soil water reserve depletes to the wilting coefficient, soon followed by the pedological drought which has negative effects on vegetation and agricultural productivity. The MODIS satellite images (Moderate Resolution Imaging Spectroradiometer allow the monitoring of the vegetation throughout the entire vegetative period, with a frequency of 1-2 days and with a spatial resolution of 250 m, 500 m and 1 km away. Another useful source of information is the LANDSAT satellite images, with a spatial resolution of 30 m. Based on MODIS and Landsat satellite images, were calculated moisture monitoring index such as SIWSI (Shortwave Infrared Water Stress Index. Consequently, some years with low moisture such as 2000, 2002, 2007 and 2012 could be identified. Spatially, the areas with moisture deficit varied from one year to another all over the whole analised period (2000-2012. The remote sensing results was corelated with Standard Precipitation Anomaly, which gives a measure of the severity of a wet or dry event.

    In recent years, multimedia annotation problem has been attracting significant research attention in multimedia and computer vision areas, especially for automatic image annotation, whose purpose is to provide an efficient and effective searching environment for users to query their images more easily.In this paper, a semi-supervised learning based probabilistic latent semantic analysis ( PL-SA) model for automatic image annotation is presenred.Since it' s often hard to obtain or create la-beled images in large quantities while unlabeled ones are easier to collect, a transductive support vector machine ( TSVM) is exploited to enhance the quality of the training image data.Then, differ-ent image features with different magnitudes will result in different performance for automatic image annotation.To this end, a Gaussian normalization method is utilized to normalize different features extracted from effective image regions segmented by the normalized cuts algorithm so as to reserve the intrinsic content of images as complete as possible.Finally, a PLSA model with asymmetric mo-dalities is constructed based on the expectation maximization( EM) algorithm to predict a candidate set of annotations with confidence scores.Extensive experiments on the general-purpose Corel5k dataset demonstrate that the proposed model can significantly improve performance of traditional PL-SA for the task of automatic image annotation.

    The present study was undertaken to determine the relationship between periodontal and cardiovascular disease. Previous studies have shown some co-relation between the two conditions. We included 186 patients divided into four groups. First two Groups (A1 & A2) were the patients with cardiac disease (100 in numbers) whilst Groups (B1 & B2) (86 in numbers) were treated as controls (without cardiac disease). Following markers of periodontal disease were assessed - plaque index, calculus index, gingival and periodontal index. Markers of cardiovascular disease included were LDL, HDL, total cholesterol and CRP. Ramfjords periodontal index was used to assess the extent of periodontal disease. In the present study there was a significant increase in CRP levels in Group A1 (CVD + PD) compared to controls and overall the two cardiac groups showed a significant increase in CRP compared to controls. There was a non-significant change in lipid profile markers (LDL, HDL and total cholesterol). Periodontal Disease Index (PDI) was also increased in Group A1 compared to other groups except Group B1 and overall in cardiac groups compared to non-cardiac (PD) groups. In this study no correlation between periodontal and cardiovascular disease was found. This may be due intake of statins by few patients in Group A with a confirmed diagnosis of cardiovascular disease.

    In a study comprising 100 patients referred to a surgical clinic with symptons suggestive of gastro-oesophageal reflux disease, the value of different diagnostic procedures was investigated. Positive acid perfusion and 24-h pH tests were the commonest findings. Forty-nine per cent showed normal oesophageal mucosa or diffuse oesophagitis at endoscopy. The severity of heartburn and regurgitation did not differ between patients with normal oesophageal mucosa and oesophagitis of various severities. The severity of macroscopic oesophagitis was significantly corelated to the total reflux time, the presence of reflux or a hiatal hernia at radiology, an open cardia or reflux at endoscopy, pressure transmission or reflux, and low lower oesophageal sphincter pressure at manometry. Gastric hypersecretion was found in 66% of the patients. Gastric acid secretion was not correlated to the severity of oesophagitis or to the findings at 24-h pH test. In patients with severe oesophagitis the sensivity for radiologic, manometric and endoscopic signs of incompetence of the gastro-oesophageal junction was 94%.

    Fusarium wilt caused by Fusarium oxysporum f. sp. ciceris (Foc) is the most serious and widespread disease of chickpea, causing a 100% loss under favorable conditions. Fourteen fungicides were evaluated against wilt pathogen In vitro with five different concentrations ranging from 1-10000 ppm. Among these only Carbendazim and Thiophanate-methyl was found as the most effective at all used concentrations. Other fungicides like Aliette, Nativo, Hombre-excel and Dividend star were found to be moderately effective. Whereas, remaining fungicides were ineffective against the targeted pathogen. Generally, a positive co-relation was observed between increasing concentrations of the tested fungicides and inhibition of Foc. Based on In vitro results Carbendazim, Thiophanate-methyl, Aliette, Dividend-star, Hombre-excel, Score and Nativo were selected for pot and field experiments. The higher concentrations of the few fungicides completely inhibited the pathogen as well as found to be phytotoxic and suppressed the plant growth while lower concentrations promoted the growth of chickpea plants. On over all bases, the Carbendazim and Thiophanate-methyl, followed by Aliette and Nativo were more effective in reducing the impact of pathogen as well as enhancing the plant growth in greenhouse experiment. Under field conditions, all fungicides except Score remarkably decreased the disease development and subsequently increased the plant growth as well as grain yield as compared to untreated plants.

    The γ-ray survey was carried out by a scintillation survey meter at O-hara area near around Hanaore Fault Zone in the northern part of Kyoto. The survey was done several times over along the same observational line. Static pattern of γ-ray intensity is revealed similar one in each other, even there is small difference. Strong intensity of γ-ray means subsistance of crushed rocks zone and a huge fault as Hanaore consists of the structure made by these weak zones. A pretty large earthquake among microearthquakes was occurred, fortunately for us, during survey period. The γ-ray survey was done just on January 6, 1978 when it was just one day before the earthquake. The observational results before the earthquake, did not give large variations of γ-ray intensity. But after 5 days from the earthquake, that is January 11, the intensity of γ-ray decreases into low value, over observational error, at almost all stations. The improvement of γ-ray was found after 2 weeks from the earthquake. Ordinarily the large fault as Hanaore is one of boundaries around block of crust, and fault zone is more sensitive to geophysical activity in the crust. Continuous observation of γ-ray will give the solution to corelation with earthquake or earthquake prediction. (author)

    Introduction. Gonial angle and antegonial region are important landmarks in mandible which is influenced by gender, age, and dental status. The objective of this study was to evaluate the gonial angle, antegonial angle, and antegonial depth and to investigate their relationship to gender, age group, and dental status. Materials and Methods. A total of 1060 panoramic radiographs were evaluated: the dentulous group, 854 subjects and the edentulous group, 206 subjects. The patients were grouped into six age groups of 10-years each. Gonial angle, antegonial angle, and antegonial depth were measured from panoramic radiographs. Results and Discussion. Corelation of age with gonial angle, antegonial angle and antegonial depth was not significant. Significant difference in mandibular angle was found between males and females. Males had significantly smaller antegonial angle and greater antegonial depth than females. Significant difference was found for gonial angle, antegonial angle, and antegonial depth between right and left sides of mandible. Conclusion. Gonial angle, antegonial angle, and antegonial depth can be implicated as a forensic tool for gender determination but not suitable for age determination

    Full Text Available The paper presents the results of a study of cyanobacteria and green algae assemblages occurring in various tundra types determined on the basis of mosses and vascular plants and habitat conditions. The research was carried out during summer in the years 2009-2013 on the north sea-coast of Hornsund fjord (West Spitsbergen, Svalbard Archipelago. 58 sites were studied in various tundra types differing in composition of vascular plants, mosses and in trophy and humidity. 141 cyanobacteria and green algae were noted in the research area in total. Cyanobacteria and green algae flora is a significant element of many tundra types and sometimes even dominate there. Despite its importance, it has not been hitherto taken into account in the description and classification of tundra. The aim of the present study was to demonstrate the legitimacy of using phycoflora in supplementing the descriptions of hitherto described tundra and distinguishing new tundra types. Numeric hierarchical-accumulative classification (MVSP 3.1 software methods were used to analyze the cyanobacterial and algal assemblages and their co-relations with particular tundra types. The analysis determined dominant and distinctive species in the communities in concordance with ecologically diverse types of tundra. The results show the importance of these organisms in the composition of the vegetation of tundra types and their role in the ecosystems of this part of the Arctic.

    Specimens taken from liver, brain, serum and ascites hepatoma 130 in rats, were bombarded with 3.5 MeV protons accelerated by a Van de graaff generator, and the induced x-ray fluorescence was analysed with a Si(Li) detector. Absolute concentrations were determined with reference to a known concentration of uranium in the specimen. Small amounts of Ga, Yb and Tl which are known as metals having tumor affinity were injected into rats implanted with ascites hepatoma and several of its derivatives. Twenty-four hours after injection, liver, brain, serum and hepatoma were removed from the rats and these specimens were analysed by the same method. Relative concentrations of Fe, Cu, Zn and Br in liver, brain, serum and hepatoma specimens showed characteristic patterns. Patterns of liver and ascites hepatoma were quite similar, but the total amount of metals in liver was greater. The serum contained a large quantity of Br. Each AH 130 tumor cell line and its derivatives showed a different accumulation rate for Ga, Yb and Tl. Tl accumulated peculiarly in the brain. There was excellent co-relation between the concentrations of the elements and the biological characteristics of the tumor. (Evans, J.)

    To compare tympanic membrane temperature and rectal temperature in febrile pediatric patients. Sixty febrile children were enrolled as continuous enrollment at initial triage. Two readings of ear temperature were taken in each child with Thermoscan infrared thermometer. Rectal temperature was recorded by a digital electronic thermometer. Comparison of both the techniques was done and co-relation co-efficients calculated. Parental preference for both techniques was assessed. It was observed that mean ear temperature was 38.9+/-0.90 C and that for rectal temperature was 38.8+/-0.80 degrees C. The correlation coefficient between the two was 0.994 (p rays emitted from the surface of tympanic membrane. Ear temperatures correlates well with rectal temperatures which have long been considered as "core" temperatures. Parents prefer the technique of ear thermometry which is quick (2 sec), safe and non-invasive and patient resistance for this is also less. A non-invasive, non-mucous device which is accurate over a wide range of temperature could be very useful.

    The structural integrity of dissimilar metal welded (DMW) joint consisting of low-alloy steel and 304LN austenitic stainless steel was examined by evaluating mechanical properties and metallurgical characteristics. INCONEL 82 and 182 were used as buttering and filler materials, respectively. Experimental findings were substantiated through thermomechanical simulation of the weld. During simulation, the effect of thermal state and stress distribution was pondered based on the real-time nuclear power plant environment. The simulation results were co-related with mechanical and microstructural characteristics. Material properties were varied significantly at different fusion boundaries across the weld line and associated with complex microstructure. During in-situ deformation testing in a scanning electron microscope, failure occurred through the buttering material. This indicated that microstructure and material properties synergistically contributed to altering the strength of DMW joints. Simulation results also depicted that the stress was maximum within the buttering material and made its weakest zone across the welded joint during service exposure. Various factors for the failure of dissimilar metal weld were analyzed. It was found that the use of IN 82 alloy as the buttering material provided a significant improvement in the joint strength and became a promising material for the fabrication of DMW joint.

    We examined cranial MRI in 62 patients with CLD. Abnormal finding that high intensity area in symmetrical bilateral basal ganglia other than globus pallidum was found on both T-1 weighted images (T1WI) and fat suppression (chemical shift selective) images. This MRI finding was observed in 32 of 41 patients with cirrhosis while 1 of 21 patients with chronic hepatitis. This MRI finding was irreversible. The incidence of this MRI finding was corelated with severity of CLD and was statistically significant between in the patients with chronic hepatitis and those with cirrhosis. The contributing factors to the incidence of this MRI finding were severity of CLD and total bilirubin level by an analysis with logistic regression model. This MRI finding was detected clearer in a fat suppression imaging than in T1WI. The cause of this MRI finding was supposed not fat related substance by the finding of fat suppression imaging. This MRI finding would be useful for prediction of severity of CLD. (author)

The aims were to evaluate treatment related fear using a newly developed fear scale for children, fear assessment picture scale (FAPS), and anxiety with colored version of modified facial affective scale (MFAS) - three faces along with physiologic responses (pulse rate and oxygen saturation) obtained by pulse oximeter before and during pulpectomy procedure. Total, 60 children of age 6-8 years who were visiting the dental hospital for the first time and needed pulpectomy treatment were selected. Children selected were of sound physical, physiological, and mental condition. Two projective scales were used; one to assess fear - FAPS and to assess anxiety - colored version of MFAS - three faces. These were co-related with the physiological responses (oxygen saturation and pulse rate) of children obtained by pulse oximeter before and during the pulpectomy procedure. Shapiro-Wilk test, McNemar's test, Wilcoxon signed ranks test, Kruskal-Wallis test, Mann-Whitney test were applied in the study. The physiological responses showed association with FAPS and MFAS though not significant. However, oxygen saturation with MFAS showed a significant change between "no anxiety" and "some anxiety" as quantified by Kruskal-Wallis test value 6.287, P = 0.043 (test is easy and fast to apply on children and reduces the chair-side time.

    Spondylolisthesis is displacement of one vertebra upon the other with bony defect of neural arch or elongation of the pars interarticularis. Radiological findings of 35 confirmed cases of spondylolisthesis on plain film and myelogram were reviewed. We also compared the size and contour of slipped vertebra, and myelographic findings between L4-L5 (12 cases) and L5-S1 (23 cases) listhesis. The results were as follows: 1. Average of posterior wedging index of the body, foreward displacement, narrowing of intervertebral disc space and the degenerative changes are more severe in L5-S1 spondylolisthesis. 2. Hyperplastic changes of slipped vertebra are more severe in L5-S1 listhesis. 3. Incidence of spina bifida is not co-related between L4-L5 and L5-SI listhesis. 4. Arthrosis of the intervertebral joint appears both below and above the level of L5-S1 listhesis, but rare in L4-L5 listhesis. 5. The L5 root seems to be the one most often affected in lumber spondylolisthesis on myelogram. 6. The diagnosis of intervertebral disc herniation is less relable in patient with listhesis than in patients without listhesis.

    Introduction. Elephantiasis is a chronic manifestation of filariasis; it commonly affects limbs, scrotum, and trunk. Females have lower incidence of filarial infection. Vulval elephantiasis due to filariasis is still rarer. It is difficult to make the diagnosis on histopathology alone, more so in view of the fact that the parasite is usually not identified in tissue sections. Identification of microfilariae in night samples of peripheral blood or seropositivity for filarial antigen is requisite for the correct diagnosis. Case Presentation. A young female presented with progressively increasing vulval swelling over a period of two years. The swelling was soft and measured 5 × 6 cm. Other possible differential diagnoses were excluded, and ancillary tests were performed to reach a conclusive diagnosis of vulval elephantiasis on histopathology. Conclusion. Vulval elephantiasis due to filariasis is rare. Its diagnosis on histopathology is more often by exclusion. High index of suspicion on microscopic findings and corelation with relevant diagnostic tests are required to reach the correct diagnosis. PMID:23198192

    We describe a technique for fabricating microfluidic devices with complex multilayer architectures using a laser printer, a CO2 laser cutter, an office laminator and common overhead transparencies as a printable substrate via a laser print, cut and laminate (PCL) methodology. The printer toner serves three functions: (i) it defines the microfluidic architecture, which is printed on the overhead transparencies; (ii) it acts as the adhesive agent for the bonding of multiple transparency layers; and (iii) it provides, in its unmodified state, printable, hydrophobic 'valves' for fluidic flow control. By using common graphics software, e.g., CorelDRAW or AutoCAD, the protocol produces microfluidic devices with a design-to-device time of ∼40 min. Devices of any shape can be generated for an array of multistep assays, with colorimetric detection of molecular species ranging from small molecules to proteins. Channels with varying depths can be formed using multiple transparency layers in which a CO2 laser is used to remove the polyester from the channel sections of the internal layers. The simplicity of the protocol, availability of the equipment and substrate and cost-effective nature of the process make microfluidic devices available to those who might benefit most from expedited, microscale chemistry.

    The biomedical investigation in Peru is limited; among the implicated factors we have the reduced per-capita expense in investigation, the disperse efforts and the low communication between the investigations and the social productive activities. To determinate the personal, professional and academic factors related with the scientific production of the medical gastroenterologists that work in province Lima. Co-relational, observational, comparative, transversal and retrospective studies that had happened in between march 2007 and april 2008. Was elaborated a survey containing the variables of the investigation which was applied autoadministered to the gastroenterologists. Using bivaried and multivaried, were identified factors related with the scientific production of the gastroenterologist. The bivaried analysis has found, as related factors with the scientific production: Teaching, type of bibliographic research, degree of comprehension of the scientific article, facilities for the investigation at the job, subscription at the scientific magazine, to belong to the scientific society and the number of employments. The multivaried analysis found the previous factors but teaching and subscription to the scientific magazine, related with the scientific production. Those gastroenterologists that, despite being in contact with factors that impede the development of the investigation, had overcome the local negative influence and emerge, deserve consideration, because is on them were we can recognize factors that favor the investigation labor.

    Full Text Available Consumers are the starting point and the focus of all activities of companies that want to survive in the long term and do business profitably on the market. However, even in the most developed economies in the world do not have all the companies awareness about the importance of social responsible business and ethical marketing. Therefore there is a need for institutional protection of consumers from unfer and unethical business of companies, on the one hand, but on the other hand, they have to encourage themselves to be more involved in the protection of their rights. The purpose of this paper is the analysis of the components of consumer attitude about the degree of protection of consumer rights in the Republic of Serbia in order to conclude on which way consumers can be encouraged to participate more actively in the exercise of rights. The aim of this study is to determine whether the cognitive, affective and behavioral component of the attitude are intercorelated and to what extent, and whether cognitive or affective component has dominant influence on forming behavioral component of the consumer attitude. Based on the results of the research about the corelation and influence of the analyzed components of the attitude we draw conclusions on which way it can be possible to affect on the consumer intention to be more engaged in its rights protection as well as on which way it can be possible to improve the consumer protection in the Republic of Serbia, generally speaking.

    Location technologies have many applications in wireless communications, military and space missions, etc. US Global Positioning System (GPS) and other existing and emerging Global Navigation Satellite Systems (GNSS) are expected to provide accurate location information to enable such applications. While GNSS systems perform very well in strong signal conditions, their operation in many urban, indoor, and space applications is not robust or even impossible due to weak signals and strong distortions. The search for less costly, faster and more sensitive receivers is still in progress. As the research community addresses more and more complicated phenomena there exists a demand on flexible multimode reference receivers, associated SDKs, and development platforms which may accelerate and facilitate the research. One of such concepts is the software GPS/GNSS receiver (GPS SDR) which permits a facilitated access to algorithmic libraries and a possibility to integrate more advanced algorithms without hardware and essential software updates. The GNU-SDR and GPS-SDR open source receiver platforms are such popular examples. This paper evaluates the performance of recently proposed block-corelator techniques for acquisition and tracking of GPS signals using open source GPS-SDR platform.

    Full Text Available Obesity has reached epidemic proportions over recent years and is related to cardiovascular risk factors, as well as to the occurrence of postural changes in adults, children and adolescents. The objective of this study was to identify the prevalence of postural abnormalities and pain in schoolchildren. Fifty-one children and adolescents of both genders aged 9-17 years were divided into an obese (n = 33 and a non-obese group (n = 18. Weight and height were measured to calculate the body mass index. A questionnaire was used to assess the presence or absence of pain. Postural deviations of the shoulder, head and knees were analyzed by photometry using the Corel Draw12 software for the determination of angular measures and size. Obese boys showed greater postural changes in the region of the knees than non-obese ones (p<0.001. No significant differences in any of the regions analyzed were observed for girls. On the other hand, the prevalence of pain was significantly higher among obese girls than among non-obese girls. We conclude that postural changes are not limited to obese children, but excess weight may increase this deviation. Further studies are needed to diagnose these changes during childhood in order to permit early intervention and good posture in adult life.

    Setting up a reliable cost unit accounting system in a hospital is a fundamental necessity for economic survival, given the current general conditions in the healthcare system. Definition of a suitable cost unit is a crucial factor for success. We present here the development and use of a clinical pathway as a cost unit as an alternative to the DRG. Elective coronary artery bypass grafting was selected as an example. Development of the clinical pathway was conducted according to a modular concept that mirrored all the treatment processes across various levels and modules. Using service records and analyses the process algorithms of the clinical pathway were developed and visualized with CorelTM iGrafix Process 2003. A detailed process cost record constituted the basis of the pathway costing, in which financial evaluation of the treatment processes was performed. The result of this study was a structured clinical pathway for coronary artery bypass grafting together with a cost calculation in the form of cost unit accounting. The use of a clinical pathway as a cost unit offers considerable advantages compared to the DRG or clinical case. The variance in the diagnoses and procedures within a pathway is minimal, so the consumption of resources is homogeneous. This leads to a considerable improvement in the value of cost unit accounting as a strategic control instrument in hospitals.

  4. Transition conductivity study of high temperature superconductor compounds: the role of fluctuations

    This memory subject is the transition conductivity study of high temperature superconductors in corelation with their anisotropy. Systematic conductivity measurements were made on YBaCuO and BaSrCaCuO in relation with temperature from 4.2 K to 1200 K, and with a magnetic field up to 8 T in several directions. Oxygen order has an effect on the characteristics at YBaCuO transition conductivity. The activation energy for oxygen absorption is about 0.5eV. One method of analysis of the conductivity fluctuations about the transition temperature is proposed. Two separate rates are noticeable in YBaCuO compound. The 3 D fluctuations rate in the immediate neighbourghood of the transition lets place to the 2 D fluctuations rate at high temperature. Transitions temperatures governing each rate are different, that's incompatible with the formula proposed by Lawrence and Doniach. On the other hand, the analogy with quasi-2 D magnetic systems seems more relevant. A magnetic field application or a lowering of oxygen concentration removes the 3 D fluctuations rate. Non ohmic effects observed at the transition conductivity foot are analysis as a non-linear 2 D excitation manifestation of the supraconductive phase. Finally, by measurements on strontium doped YBaCuO crystals, we confirm a metal-insulator transition along the C-Axe when oxygen concentration reduces. This is connected with the specific heat jump. All these results uplighten the fundamental bidimensional character of high transition temperature superconductivity [fr

    The Steady State Superconducting Tokamak (SST-1) consists of many distributed and heterogeneous plant/experiment systems viz. Water-Cooling, Power Supplies, Cryogenics, Vacuum, Magnets, Auxiliary-Heating sources, Diagnostics, Front End Electronics (FEE) & Data Acquisition systems, having their own data acquisition & control systems and control & monitor by Central Control System (CCS) during the machine operation. With distributed computing and interdependent systems, it is essential that all the data/event acquired must be with disciplined & precise time-base, so as to make the co-relation of the data/event from various plant and experiment systems easy. Hence it is important to have accurate and precise Time Synchronization in place. The two systems fulfill the requirement of the time synchronization in SST-1. The VME based Timing System (TS) provides synchronization amongst various experiment systems during the plasma discharges and works as discharge control system (DCS) while the GPS based Time Synchronization System (TSS) caters the requirement of synchronization during the continuous operation of various plant systems by feeding a central clock to all the plant systems. This paper presents the Time Synchronization System of SST-1, the results of the integrated testing and engineering validation with various SST-1 subsystems.

    Highlights: •Vanadium prevents the pulverization of LaNi 5 . •H absorption capacity LaNi 5 –V composite is higher than LaNi 5 . •H absorption kinetics of LaNi 5 –V composite is relatively faster than V and LaNi 5 . •Fermi energy level of LaNi 5 –V composite lowered by vanadium addition. -- Abstract: The hydrogen absorption behavior of V + 80 wt.% LaNi 5 composite, LaNi 5 and V has been investigated. The LaNi 5 –V composite was prepared by high energy ball-milling technique using high pure vanadium and LaNi 5 powder. Lattice expansion of the composite has been observed in X-ray analysis which indicates the solid solution formation. Presence of free V and traces of V 2 O 5 phase were also observed in the composite. The hydrogen absorption capacity and absorption kinetics of the composite showed improvement as compared to LaNi 5 . The improved kinetics of the composite has been co-related to the change in lattices parameter, Fermi energy level and catalytic property of vanadium. Integrity of the composite has found to be effective even after 20 numbers of hydriding and dehydriding cycles due to the presence of vanadium

    Cervical cancer which is one of the most preventable cancers is an important public health problem worldwide, and especially in developing countries. The aim of this study was to determine knowledge and attitudes about the HPV vaccination of mothers with 0- to 18-year old children. Written approval was taken from the local authorities. The study subjects consisted of 799 mothers who agreed to participate. The data were collected via a "Personal Information Form" which included 30 questions that were prepared by the researchers themselves in line with the literature. The data were collected by face to face interviews with the mothers. Analyses were performed using commercial software. The mean age of the mothers who participated in the study was 32.0 ± 6.52, and 88.1% reported no information about HPV, and 83.5% no information about HPV vaccination. Only 0.7% of the mothers had daughters who had HPV vaccination, and 44.3% of the mothers who had sons were found out to be indecisive about having HPV vaccination. There was a significant corelation between the educational status of the mothers and their knowledge about HPV vaccination (p0.05). This study suggested that mothers had very little information on HPV and HPV vaccination. Knowledge of the disease and its vaccination is an essential factor for the success of the vaccination program. It is of great importance that mothers are trained in this subject by health professionals.

    Full Text Available Speed-flow functions have been developed by several transportation experts to predict accurately the speed of urban road networks. HCM Speed-Flow Curve, BPR Curve, MTC Speed-Flow Curve, Akçelik Speed-Flow Curve are some extraordinary efforts to define the shape of speed-flow curves. However, the complexity of driver's behaviour, interactions among different type of vehicles, lateral clearance, co-relation of driver's psychology with vehicular characteristics and interdependence of various variables of traffic has led to continuous development and refinement of speed-flow curves. The problem gets more difficult in the case of urban roads with heterogeneous traffic, oversaturated flow and signalized network (which includes some unsignalized intersections as well. This paper presents analysis for various measures of effectiveness (MOE for urban roads with interrupted flow comprising heterogeneous traffic. Model has been developed for heterogeneous traffic under constraints of roadway geometry, vehicle characteristics, driving behaviour and traffic controls. The model developed in this paper predicts speed, delay, average queue and maximum queue estimates for urban roads and quantifies congestion for oversaturated conditions. The investigation details the oversaturated portion of flow in particular.

    Full Text Available Aims and Objectives : A relationship between poor periodontal health and respiratory disease has been suggested by a number of recent studies. The present study was undertaken to evaluate potential association between respiratory diseases and periodontal health status and to co-relate the severity of periodontal disease with that of chronic obstructive pulmonary disease (COPD. Materials and Methods : 150 patients of COPD (test group and 50 Patients without COPD (control group were recruited for the study. Information regarding patient′s demographic and socioeconomic status and lifestyle (history of smoking were considered in the study. Patients with COPD were grouped into mild, moderate and severe category on the basis of Spirometry. Periodontal health was assessed by measuring probing pocket depth, Clinical Attachment Loss (CAL and Oral Hygiene Index (OHI. Results : The results showed that the subjects with COPD had significantly more mean CAL and a higher mean OHI than those without COPD. The risk for COPD appeared to be significantly elevated when attachment loss was found to be severe. A trend was noted in that lung function appeared to diminish as the amount of attachment loss increased. Conclusion : On the basis of the observed results of the study it can be concluded that the risk for COPD appeared to be significantly elevated when attachment loss was found to be severe. It is conceivable that oral interventions that improve oral health status may prove to lower the severity of lung infection in susceptible populations.

    Apart from the reidual stresses present in the bulk material, a growing fatigue crack may develop its own stress field ahead of the crack tip which in turn could influence the crack propagation behaviour. A fracture surface analysis through measurement of the residual stress of a failed component may provide some additional useful information to that obtained through conventional metallurgical and fracture mechanics investigations. This method of fracture surface analysis using x-ray diffraction technique is known as X -ray Fractography . Residual stress (ρ sub γ) and the full width at half maximum (FWHM) of the x-ray diffraction profile of any reflection are determined at different crack lengths on the fracture surface. These are then corelated to the fracture toughness parameters such as fracture toughness K sub I sub C, the maximum stress intensity factor K sub max and the stress intensity factor range δK. The present investigation aims at detailed x-ray analysis of the fatigue fractured surfaces of the compact tension specimens prepared from ferritic and austenitic stainless steels. The ferritic steel has been subjected to various heat treatments to obtain different microstructures and mechanical properties. The overall observations are analyzed through fatigue (cumulative) damage and material science concepts

    Highly porous spinel MgFe2O4 nanoparticles with a high specific surface area have been successfully synthesized by a sintering free auto-combustion technique and characterized for their structural and surface morphological properties using XRD, BET, TEM and SEM techniques. Their sensing properties to alcohol vapors viz. ethanol and methanol were investigated. The site occupation of metal ions was investigated by VSM. The as-synthesized sample shows the formation of sponge-like porous material which is necessary for gas adsorption. The gas sensing characteristics were obtained by measuring the gas response as a function of operating temperature, concentration of the gas, and the response-recovery time. The response of magnesium ferrite to ethanol and methanol vapors was compared and it was revealed that magnesium ferrite is more sensitive and selective to ethanol vapor. The sensor operates at a substantially low vapor concentration of about 1 ppm of alcohol vapors, exhibits fantastic response reproducibility, long term reliability and a very fast response and recovery property. Thus the present study explored the possibility of making rapidly responding alcohol vapor sensor based on magnesium ferrite. The sensing mechanism has been discussed in co-relation with magnetic and morphological properties. The role of occupancy of Mg2+ ions in magnesium ferrite on its gas sensing properties has also been studied and is found to influence the response of magnesium ferrite ethanol sensor.

    Full Text Available The literature review examines globalization and landscape architecture as discourse, samples its various meanings, and proposes methods to identify and contextualize its specific literature. Methodologically, the review surveys published articles and books by leading authors and within the WorldCat.org Database associated with landscape architecture and globalization, analyzing survey results for comprehensive conceptual and co-relational frameworks. Three “higher order” dimensions frame the review’s conceptual organization, facilitating the organization of subordinate/subtopical areas of interest useful for comparative analysis. Comparative analysis of the literature suggests an uneven clustering of discipline-related subject matter across the literature’s “higher order” dimensions, with a much smaller body of literature related to landscape architecture confined primarily to topics associated with the dispersion of global phenomena. A subcomponent of this smaller body of literature is associated with other fields of study, but inferentially related to landscape architecture. The review offers separate references and bibliographies for globalization literature in general and globalization and landscape architecture literature, specifically.

    A comprehensive investigation was conducted in order to assess the levels of PAHs, their input prediction and potential risks to bacterial abundance and human health along Gujarat coastline. A total of 40 sediment samples were collected at quarterly intervals within a year from two contaminated sites-Alang-Sosiya Shipbreaking Yard (ASSBRY) and Navlakhi Port (NAV), situated at Gulf of Khambhat and Gulf of Kutch, respectively. The concentration of ΣPAHs ranged from 408.00 to 54240.45 ng g -1  dw, indicating heavy pollution of PAHs at both the contaminated sites. Furthermore, isomeric ratios and principal component analysis have revealed that inputs of PAHs at both contaminated sites were mixed-pyrogenic and petrogenic. Pearson co-relation test and regression analysis have disclosed Nap, Acel and Phe as major predictors for bacterial abundance at both contaminated sites. Significantly, cancer risk assessment of the PAHs has been exercised based on incremental lifetime cancer risks. Overall, index of cancer risk of PAHs for ASSBRY and NAV ranged from 4.11 × 10 -6 -2.11 × 10 -5 and 9.08 × 10 -6 -4.50 × 10 -3 indicating higher cancer risk at NAV compared to ASSBRY. The present findings provide baseline information that may help in developing advanced bioremediation and bioleaching strategies to minimize biological risk.

    A computerized quality assurance kit to provide precise measurement and calibration of microwave power and temperature, as well as capabilities to map SAR (Specific absorption rate) distribution in phantoms; and survey of hazardous microwave leakage has been designed. The kit is also capable of performing corelation studies on the relationship between SAR and net microwave power delivered at various anatomical sites. The kit consists of a portable microcomputer, a time-multiplexed A/D converter, a 4-channel dual directional microwave power monitor, a 4-channel thin-wire thermocouple thermometry system, an electronic thermal calibrator, a microwave leakage hazard survey meter, and a dynamic phantom tank for dosimetric analysis. Comparative performance studies were made against NBS-traceable power and temperature standards, non-perturbing optical temperature sensors, and established power and temperature measurement devices. The test results indicate that this instrument is providing its user with measurement accuracy of 0.1 0 C in temperature, 10% accuracy in power. The thin-wire thermocouple, with computer assisted error compensation, performs equally well in a strong microwave field in comparison with non-perturbing optical temperature sensors

    Full Text Available Kombucha has been known as traditional medicine that can cure various diseases, such as hypercholesterol. Kombucha made of fermented sweetened tea using symbiotic growth of khamir and bacteria. Functional properties of kombucha related to metabolite that has been produced during fermentation process, glucuronic acid. The aim of this research was to get a fit carbon source that can produce kombucha which have highest glucuronic acid. The result showed that microbe that dominated at the beginning through the end of fermentation process was a group of khamir, i.e 1.81x107 ; 1.43x106 ; 2.40x107 ; 7.00x104 CFU/mL for 1, 4, 7, and 10% of additive coconut sugar. Kombucha at 4% of coconut sugar yielded 8.86 ppm of glucuronic acid. Meanwhile, kombucha with 10% of coconut sugar yielded 6.22 ppm of glucuronic acid. Total acid has no corelation with glucuronid acid formation during the fermentation process.

    To show the most outstanding findings from the chronic scrotal pathology of adults and boys, determining the benefits of the Doppler echography in the diagnostical valuation of the different cases analysed. 40 patients (19 adults and 21 boys) with chronic scrotal symptomatology were examined using a B mode echography followed by a colour duplex-Doppler (CDD) echography with a lineal 7.5 MHz transducer. We compared the findings obtained with those corresponding to the contralateral testicle and, depending on the pathology, we co-related them with surgery, pathologic anatomy or clinical-echograph evolution. The pathology found was very varied, it was distributed into: varicoceles (12), testicle tumours (9), extra-testicle tumours (4) and miscellaneous pathology (13). Two patients showed no changes, currently remaining asymptomatic. The treatment was surgical in 28 (70%) of the patients and traditional in the others. The B mode echography played a fundamental role in the diagnosis of chronic scrotal pathology, which in the majority of the cases was definitive, being completed with the application of the Doppler echograph to analyse the vascular condition of the lesions and the anatomical structures. The diagnosis utility of the CDD echograph in chronic scrotal pathology is controversial, it is not specific for testicle tumors, it is very useful for variocele and complementary, tp the B mode echograph for miscellaneous pathology.

    Accurate diagnosis is critical to both therapeutic decisions and prognostication in interstitial lung diseases (ILD). However, surgical lung biopsies carry high complication rates. Fibred confocal fluorescence microscopy (FCFM) offers an alternative as it can visualize lung tissue in vivo at the cellular level with minimal adverse events. We wanted to investigate the diagnostic utility, and safety of using FCFM for patients with ILD. In patients with suspected ILD, FCFM images were obtained from multiple bronchopulmonary segments using a miniprobe inserted through the working channel of a flexible bronchoscope. The procedure was performed under moderate sedation in an outpatient setting. Morphometric measurements and fibre pattern analyses were co-related with computed tomography (CT) findings and patients' final diagnoses based on multi-disciplinary consensus. One hundred and eighty four segments were imaged in 27 patients (18 males) with a median age of 67 years (range, 24-79 years). They were grouped into chronic fibrosing interstitial pneumonia (16 patients) and other ILDs. Six distinct FCFM patterns were observed: normal, increased fibres, densely packed fibres, hypercellular, thickened fibres and others/non-specific. The pattern resembling densely packed fibres was seen in at least one segment in 68.8% patients with chronic fibrosing interstitial pneumonia, but only 36.4% in other ILD (P=0.097). An association between inflammatory patterns on CT and a hypercellular pattern on FCFM was also found (P<0.001). Our study shows the potential of FCFM in classifying ILD, but its role in further diagnosis remains limited.

    Objective: To assess the utility of liver function tests (LFTs) for early recognition and prediction of severity of Dengue fever in hospitalized patients. Study Design: An analytical study. Place and Duration of Study: Services Institute of Medical Science and Fatima Memorial Hospital, Lahore, from September - December 2010. Methodology: Admitted cases of Dengue fever were divided into 3 groups; mild, moderate and severe increases in aminotransferases. Elevation in LFTs was co-related with good or bad outcome i.e. (survival or complication free stay) or (death or complications). Results were analyzed in SPSS version 18. Results: Out of the 353 patients with mean age of 37.12 +- 15.45 years, 245 (69.4%) were males and 108 (30.6%) were females. Seventy five patients (21.2%) had mild elevation of aminotransferases (2 fold increases), 265 patients (75.1%) had moderate increases (3 to 4 fold) and 13 (3.7%) had severe (> 4 fold increase). ALT was statistically higher in patients with septicemia, hepatic and renal failure (p-value 0.05). AST was higher in almost all complications. Prolonged hospital stay was associated with raised LFTs and greater complications and mortality. AST was found to be twice as much raised as ALT. Conclusion: AST and ALT were statistically higher in patients with worse outcome thus can lead to early recognition of high risk cases. (author)

    2010-02-01

    With many potential multimedia applications, content-based image retrieval (CBIR) has recently gained more attention for image management and web search. A wide variety of relevance feedback (RF) algorithms have been developed in recent years to improve the performance of CBIR systems. These RF algorithms capture user's preferences and bridge the semantic gap. However, there is still a big room to further the RF performance, because the popular RF algorithms ignore the manifold structure of image low-level visual features. In this paper, we propose the biased discriminative Euclidean embedding (BDEE) which parameterises samples in the original high-dimensional ambient space to discover the intrinsic coordinate of image low-level visual features. BDEE precisely models both the intraclass geometry and interclass discrimination and never meets the undersampled problem. To consider unlabelled samples, a manifold regularization-based item is introduced and combined with BDEE to form the semi-supervised BDEE, or semi-BDEE for short. To justify the effectiveness of the proposed BDEE and semi-BDEE, we compare them against the conventional RF algorithms and show a significant improvement in terms of accuracy and stability based on a subset of the Corel image gallery.

    Treatment of Duchenne muscular dystrophy (DMD) by replacing mutant dystrophin or restoring dystrophin-associated glycoprotein complex (DAG) has been clinically challenging. Instead, identifying and targeting muscle pathways deregulated in DMD will provide new therapeutic avenues. We report that the expression of nuclear receptor estrogen-related receptor-γ (ERRγ), and its metabolic and angiogenic targets are down-regulated (50-85%) in skeletal muscles of mdx mice (DMD model) vs. wild-type mice. Corelatively, oxidative myofibers, muscle vasculature, and exercise tolerance (33%) are decreased in mdx vs. wild-type mice. Overexpressing ERRγ selectively in the dystrophic muscles of the mdx mice restored metabolic and angiogenic gene expression compared with control mdx mice. Further, ERRγ enhanced muscle oxidative myofibers, vasculature, and blood flow (by 33-66%) and improved exercise tolerance (by 75%) in the dystrophic mice. Restoring muscle ERRγ pathway ameliorated muscle damage and also prevented DMD hallmarks of postexercise muscle damage, hypoxia, and fatigue in mdx mice. Notably, ERRγ did not restore sarcolemmal DAG complex, which is thus dispensable for antidystrophic effects of ERRγ. In summary, ERRγ-dependent metabolic and angiogenic gene program is defective in DMD, and we demonstrate that its restoration is a potential strategy for treating muscular dystrophy.

    The glasses of the batch xPbO: 10BaO: (90-x)B2O3: 0.2Gd2O3 (x = 40,45,50 mol %) were prepared by melt-quench technique. The work emphasizes on gamma ray shielding effect on doped lead glasses. The role of Boron is significant as it acts as better neutron attenuator as compared with any other materials, as the thermal neutron cross-sections are high for Gadolinium, 0.2 mol% is chosen as the optimum concentration for this matrix, as higher the concentration may lead to further increase as it produces secondary γ rays due to inelastic neutron scattering. Shielding effects were studied using Sodium Iodide (NaI) - Scintillation Gamma ray spectrometer. It was found that at higher concentration of lead oxide (PbO) in the matrix, higher the attenuation which can be co-related with density. Infra-red (I.R.) spectra reveals that the conversion of Lose triangles to tight tetrahedral structure results in enhancement of shielding properties. The Differential Scanning Calorimeter (D.S.C.) study also reveals that the increase in glass forming range increases the stability which in-turn results in inter-conversion of BO3 to BO4 units such that the density of glass increases with increase in PbO content, resulting in much stable and efficient gamma ray shielding glasses.

    Growth suitability as assessment indicators for medicinal plants cultivation was proposed based on chemical quality determination and ecological factors analysis by Maxent and ArcGIS model. Notopterygium incisum, an endangered Chinese medicinal plant, was analyzed as a case, its potential distribution areas at different suitability grade and regionalization map were formulated based on growth suitability theory. The results showed that the most suitable habitats is Sichuan province, and more than 60% of the most suitable areawas located in the western Sichuan such as Aba and Ganzi prefectures for N. incisum. The results indicated that habitat altitude, average air temperature in September, and vegetation types were the dominant factors contributing to the grade of plant growth, precipitation and slope were the major factors contributing to notopterol accumulation in its underground parts, while isoimperatorin in its underground parts was negatively corelated with precipitation and slope of its habitat. However, slope as a factor influencing chemical components seemed to be a pseudo corelationship. Therefore, there were distinguishing differences between growth suitability and quality suitability for medicinal plants, which was helpful to further research and practice of cultivation regionalization, wild resource monitoring and large-scale cultivation of traditional Chinese medicine plants.

    The aim of the study was identification of statistically reliable correlations and the cause-effect relationships between viability of red blood cells and dislipidema parametres and/or metabolic disorders, induced by age related alterations of estrogen content, in women of different ages (reproductive, menopausal) On the basis of the analysis of research results we can conclude that in the different age groups of women with atherosclerosis-induced cardiovascular diseases revealed estrogen-related dependence between Tg-s and HDL content, functional status of phereperial blood erytrotcites and severity of dislipidemia. The aterogenic index Tg/HD proved to be sensitive marker of dislipidemia in reproductive aging women, but does't reflect disorders of lipid metabolism in postmenosal women. It was proved the existence of reliable corelation between red blood cells dysfunction indicator, spherulation quality, and atherogenic index Tg/HDL highlights; however, the correlation coefficient is 2 times higher in the reproductive age as in menopause. Spherulation quality of red blood cells at low HDL content showd fast growth rate in reproductive-aged women, and was unsensetive to HDL content in postmenopasal women. It was concluded that age-related lack of estrogens in postmenopausal women indirectly contributes to decrease protection of red blood cells against oxidative damage, reduces their deformabelity and disturbances the rheological properties. So, Spherulation quality of red blood cells may be used as a diagnostic marker of severity of atherosclerosis.

    Multiphase blends of poly(lactic acid) (PLA), ethylene-methyl acrylate-glycidyl methacrylate (EMA-GMA) terpolymer, and a series of renewable poly(ether-b-amide) elastomeric copolymer (PEBA) were fabricated through reactive melt blending in an effort to improve the toughness of the PLA. Supertoughened PLA blend showing impact strength of ∼500 J/m with partial break impact behavior was achieved at an optimized blending ratio of 70 wt % PLA, 20 wt % EMA-GMA, and 10 wt % PEBA. Miscibility and thermal behavior of the binary blends PLA/PEBA and PLA/EMA-GMA, and the multiphase blends were also investigated through differential scanning calorimetric (DSC) and dynamic mechanical analysis (DMA). Phase morphology and fracture surface morphology of the blends were studied through scanning electron microscopy (SEM) and atomic force microscopy (AFM) to understand the strong corelation between the morphology and its significant effect on imparting tremendous improvement in toughness. A unique "multiple stacked structure" with partial encapsulation of EMA-GMA and PEBA minor phases was observed for the PLA/EMA-GMA/PEBA (70/20/10) revealing the importance of particular blend composition in enhancing the toughness. Toughening mechanism behind the supertoughened PLA blends have been established by studying the impact fractured surface morphology at different zones of fracture. Synergistic effect of good interfacial adhesion and interfacial cavitations followed by massive shear yielding of the matrix was believed to contribute to the enormous toughening effect observed in these multiphase blends.

A selection was made of 45 extracted, human, mandibular molars, with root curvatures greater than 25°. They were divided into three groups for every technique studied, which were then sub-divided into three sub-groups in accordance with the position of the curvature along the root: cervical, median or apical. After access surgery and tooth length determination, the canals were filled with 100% Barium Sulphate radiological contrast and the teeth were then radiographed with a direct digital radiography system, using a special apparatus capable of keeping the samples in the same spatial position during the different radiographic takes. After the above-mentioned endodontic techniques had been performed, the teeth were again filled with Barium sulphate and were also radiographed under the same previously mentioned conditions. The pre- and post-operative digital images were then analyzed in two computerized programs, AutoCAD 2004 and CorelDraw 10, to assess, respectively, the areas and the horizontal alterations which occurred in the internal and external walls of the root canals. The results indicated that although no significant differences among the techniques were shown in the statistical analysis, in a descriptive analysis the Progressive Preparation technique was shown to be more regular, uniform and effective.Objetivou-se comparar, in vitro, através de análise computadorizada de imagens radiográficas digitais, as alterações anatômicas promovidas nas paredes dentinárias de canais mésio-vestibulares com curvatura severa de molares inferiores por três técnicas endodônticas diferentes: Preparo Progressivo

    Full Text Available India is one of the 12 mega biodiversity countries of the world, which represents 11% of world's flora in about 2.4% of global land mass. Approximately 28% of the total Indian flora and 33% of angiosperms occurring in India are endemic. Higher human population density in biodiversity hotspots in India puts undue pressure on these sensitive eco-regions. In the present study, we predict the future distribution of 637 endemic plant species from three biodiversity hotspots in India; Himalaya, Western Ghats, Indo-Burma, based on A1B scenario for year 2050 and 2080. We develop individual variable based models as well as mixed models in MaxEnt by combining ten least co-related bioclimatic variables, two disturbance variables and one physiography variable as predictor variables. The projected changes suggest that the endemic flora will be adversely impacted, even under such a moderate climate scenario. The future distribution is predicted to shift in northern and north-eastern direction in Himalaya and Indo-Burma, while in southern and south-western direction in Western Ghats, due to cooler climatic conditions in these regions. In the future distribution of endemic plants, we observe a significant shift and reduction in the distribution range compared to the present distribution. The model predicts a 23.99% range reduction and a 7.70% range expansion in future distribution by 2050, while a 41.34% range reduction and a 24.10% range expansion by 2080. Integration of disturbance and physiography variables along with bioclimatic variables in the models improved the prediction accuracy. Mixed models provide most accurate results for most of the combinations of climatic and non-climatic variables as compared to individual variable based models. We conclude that a regions with cooler climates and higher moisture availability could serve as refugia for endemic plants in future climatic conditions; b mixed models provide more accurate results, compared to single

  5. A theoretical and experimental investigation of creep problems with variable temperature

    1975-01-01

    This paper attempts to delineate the principal features of the behavior when load level are maintained at those appropriate to many design situations and when the temperature and loading histories are cyclic with relatively short cycle times. It is concerned with structures which accumulate creep strains of less than 1% per year and have cycle times of the order of a few days at most. In the first section the behavior of a few simple structures are investigated for spatially varying temperature fields which remain constant in time. Adopting an appropriate form of Norton's Law we show that the deformation of the structure may be related to a single reference material test conducted at a reference stress and a reference temperature, which is independent of material constants, thereby providing a generalization of the reference stress method for isothermal structures. A sequence of experiments on a simple beam structure indicates that the co-relation between structural behavior and material tests provides an acceptably accurate design method. The last section discussed a preliminary experimental investigation of a two-bar structure subject to variable temperature. It is shown that the residual stress field varies quite slowly in time and remains effectively constant after a few cycles. The theoretical consequences of the results are discussed and it is shown that constitutive relationships with differing physical assumptions can yield quite sharply contrasting deformation rates. The results of the paper show that the behavior of structures subject to a time constant temperature distribution may be related to material behavior without difficulty. When temperature and load vary with time, the more important feature of the structural behavior may be understood, although certain features of the material behavior remain ill-defined

    Objective of the current study was to evaluate proportions of frontal facial soft-tissues of Vietnamese females correspond to the golden proportion (GP). Sixty frontal facial photographs of Vietnamese female students aged 19 years were selected. The selected participants had symmetrical face, a Class I relationship occlusion, complete lip closure, and no history of trauma and orthodontic treatment. The photographic record was set-up with a white backdrop, fill light, a reflector, a camera Canon 650D and subjects were asked to sit in a standard position. Trichion (TR), Temporal soft tissue (TS), Lateral canthus (LC), Lateral nasal (LN), Chilion (CH), and Menton (ME) point were used for photometric measurements on CorelDRAW Graphic X3 software. The vertical facial proportions (mean, percentage compared with GP) were significantly higher than the GP including: LC-CH:CH-ME (1.661, 102%), LN-ME:LC-LN (1.729, 106%), TR-ME:LC-ME (1.739, 107%), TR-LN:LN-ME (1.759, 108%). Whereas TR-ME:LN-ME; CH-ME:LN-CH; LC-LN:LN-CH had ratios of 84% - 92% and were significantly smaller in comparison with GP. The horizontal facial proportions of CHR-L:LNR-L, LCR-L:CHR-L and TSR-L:LCR-L deviated from the GP with mean values of 1.221, 1.922 and 1.229, respectively. The new mean values of TR-ME:LC-ME (1.733), TR-LN:LN-ME (1.732), LC-ME:TR-LC (1.374), CH-ME:LN-CH (1.524), which were predictable changes in proportions, can be significantly converged to the GP if LC-CH:CH-ME is equal to the GP. Soft-tissue facial proportions of Vietnamese females did not correspond to the GP. Changing the lower third face may create harmony vertical facial proportions.

    Gonadotropin-releasing hormone(GnRH) analogues have been used as a conservative or preoperative therapy in the treatment of uterine leiomyoma. Since these drugs, which can induce a low estrogenic state, affect only undegenerative leiomyoma tissue, the aim of the present study was to differentiate degenerative leiomyoma from undegenerative one by Gd-DTPA enhanced magnetic resonance imaging(MRI). There were 40 masses in 24 patients; all were diagnosed by surgical-pathology. With superconductive 0.5T MR circuit, T1-and T2-weighted images and Gd-DTPA T1-weighted images were obtained. Based on a combination of signal intensities of T2-weighted and enhanced T1 weighted image on the same tumor section all the lesions were classified to one of four MRI patterns. Pattern I was a heterogeneous hyperintensity on the T2-weighted images that was enhancement by Gd-DTPA. Pattern II was a high signal intensity on the T2-weighted MR images but no enhancement by Gd-DTPA. Pattern III was a low to intermediate signal intensity on the T2-weighted MR images and enhancement on the Gd-DTPA T1-weighted images. Pattern IV was a low to intermediate signal intensity on the T2-weighted images and no enhancement by Gd-DTPA. Each of these 4 groups of MRI pattern were co-related to the surgical-pathology findings. Pathologically, pattern I corresponded to an edematous leiomyoma in 3 cases and a connective tissue leiomyoma in one case. Pattern II corresponded to three red degeneration, two cystic degeneration and one infected leiomyoma. Pattern III corresponded to eighteen undegenerative leiomyomas, but some of them showed focal connective tissue proliferation. All of twelve cases in pattern IV corresponded to a hyaline degeneration. MRI with Gd-DTPA enhancement may differentiate undegenerative leiomyoma from degenerated one

  9. The possibility to increase the rated output as a result of index tests performed in Iron Gates II- Romania

    2010-08-01

    The Index Tests have been used for many years to obtain the optimized cam corellation between wicket gates and runner blades for double regulated turbines (Kaplan, bulb). The cam is based on homologous model tests and is verified by site measurements, as model tests generally do not reproduce the exact intake configuration. Index Tests have also a considerable importance for checking of the relative efficiency curve of all type of turbines and can demonstrate if the prototype efficiency curve at plant condition has the shape expected from the test of the homologues model. During the Index Tests measurements the influence of all losses at multiple points of turbine operation can be proved. This publication deals with an overview on the Index Tests made after modernization of large bulb units in Iron Gates II - Romania. These field tests, together with the comparative, fully homologous tests for the new hydraulic shape of the runner blades have confirmed the smooth operational behavior and the guaranteed performance. Over the whole "guaranteed operating range" for H = 8m, the characteristic of the Kaplan curve (enveloping curve to the proppeler curves), agreed very well to the predicted efficiency curve from the hydraulic prototype hill chart. The new cam correlation have been determined for different head and realised in the governor, normally based on model tests. The guaranteed, maximum turbine output for H = 7,8m is specified with 32, 5 MW. The maximum measured turbine output during the Index Tests on cam operation was 35,704 MW at the net head of 7,836 m. This coresponds to 35,458 MW for the specified head H= 7, 8 m. All these important improvements ensure a significant increase of annual energy production without any change of the civil construction and without increasing the runner diameter. Also the possibility to increase the turbine rated output is evident.

    The main objective of the paper is to reduce the pollutant emissions of a compression ignition engine, fuelling the engine with liquefied petroleum gas (LPG), aiming to maintain the energetic performances of the engine. To optimise the engine operation a corelation between the substitute ratio of the diesel fuel with LPG and the adjustments for the investigated regimens must be made in order to limit the maximum pressure and smoke level, knock and rough engine functioning, fuel consumption and the level of the pollutant emissions. The test bed situated in the Thermotechnics, Engines, Thermal Equipments and Refrigeration Instalations Department was adapted to be fuelled with liquefied petroleum gas. A conventional LPG fuelling instalation was adopted, consisting of a LPG tank, a vaporiser, conections between the tank and the vaporiser and a valve to adjust the gaseous fuel flow. Using the diesel-gas methode, in the intake manifold of the engine is injected LPG in gaseous aggregation state and the airr-LPG homogeneous mixture is ignited from the flame appeared in the diesel fuel sprays. To maintain the engine power at the same level like in the standard case of fuelling only with diesel fuel, for each investigated operate regimen the diesel fuel dose was reduced, being energetically substituted with LPG. The engine used for experimental investigations is a turbocharged truck diesel engine with a 10.34 dm3 displacement. The investigated working regimen was 40% load and 1750 rpm and the energetic substitute ratios of the diesel fuel with LPG was situated between [0-25%].

    This memory subject is the transition conductivity study of high temperature superconductors in corelation with their anisotropy. Systematic conductivity measurements were made on YBaCuO and BaSrCaCuO in relation with temperature from 4.2 K to 1200 K, and with a magnetic field up to 8 T in several directions. Oxygen order has an effect on the characteristics at YBaCuO transition conductivity. The activation energy for oxygen absorption is about 0.5eV. One method of analysis of the conductivity fluctuations about the transition temperature is proposed. Two separate rates are noticeable in YBaCuO compound. The 3 D fluctuations rate in the immediate neighbourghood of the transition lets place to the 2 D fluctuations rate at high temperature. Transitions temperatures governing each rate are different, that`s incompatible with the formula proposed by Lawrence and Doniach. On the other hand, the analogy with quasi-2 D magnetic systems seems more relevant. A magnetic field application or a lowering of oxygen concentration removes the 3 D fluctuations rate. Non ohmic effects observed at the transition conductivity foot are analysis as a non-linear 2 D excitation manifestation of the supraconductive phase. Finally, by measurements on strontium doped YBaCuO crystals, we confirm a metal-insulator transition along the C-Axe when oxygen concentration reduces. This is connected with the specific heat jump. All these results uplighten the fundamental bidimensional character of high transition temperature superconductivity.

In bio-medical field, many researches in GP are focused on the recognition of cancerous cells and also on gene expression profiling data. In this research, the aim is to study the performance of GP on the survival prediction of a small sample size of oral cancer prognosis dataset, which is the first study in the field of oral cancer prognosis. Method GP is applied on an oral cancer dataset that contains 31 cases collected from the Malaysia Oral Cancer Database and Tissue Bank System (MOCDTBS. The feature subsets that is automatically selected through GP were noted and the influences of this subset on the results of GP were recorded. In addition, a comparison between the GP performance and that of the Support Vector Machine (SVM and logistic regression (LR are also done in order to verify the predictive capabilities of the GP. Result The result shows that GP performed the best (average accuracy of 83.87% and average AUROC of 0.8341 when the features selected are smoking, drinking, chewing, histological differentiation of SCC, and oncogene p63. In addition, based on the comparison results, we found that the GP outperformed the SVM and LR in oral cancer prognosis. Discussion Some of the features in the dataset are found to be statistically co-related. This is because the accuracy of the GP prediction drops when one of the feature in the best feature subset is excluded. Thus, GP provides an automatic feature selection function, which chooses features that are highly correlated to the prognosis of oral cancer. This makes GP an ideal prediction model for cancer clinical and genomic data that can be used to aid physicians in their decision making stage of diagnosis or prognosis.

    Though the knowledge about the risk of elevated intraocular pressure for pathogenesis for development and progress of glaucoma is more than 400 years old. It took another 300 years before by means of tonometry this elevation could be quantified. After discussion of the key words it is our aim to demonstrate the latest trends in tonometry, specifically by use of modern electronics for instrument design. Goldmann was the founder of the "applanation tonometry", measuring the corelation of applanated area and applied force. Here, the next step was the development of instruments, measuring independent of position or gravity to allow application also at the lying patient. Electronic area detection was the next step to avoid examinor's error. Also important was the introduction of automatic UV-desinfection to avoid contamination of the other eye or other patients. Other tonometers control the force applied by an inductive method, which also allows application independent of position. Airpuff-tonometry uses completely different measuring principles - the resulting change of corneal curvature indicates the intraocular pressure. The impedance principle is applied even through the closed eye lid. The shock waves resulting shall be measured. Direct application of a surface sensor incorporated into a concave surface contact body shall allow direct measurement of intraocular pressure independent of corneal thickness, curvature, astigmatism. This method has been tried for more than 20 years. Also exposition of the eye to count waves of different frequency was an early attempt. Here also change of reflectivity is used to calculate intraocular pressure. Even after use of modern electronic technology the precision of many of these new devices does not lead to better results. This specifically is shown by modern calibration methods.

    The tactical use of visuoperceptual content in marketing may encourage impulsive consumption of unhealthy products. In this study, the application of visuoperceptual content was compared in advertisements used by industries of tobacco, alcohol and food. The aim was to ascertain whether similarities exist in the strategies used as variables for the selection of commercial stimuli, such as color, position and size. Scion Image and Corel Draw Graphics Suite software were used to analyze the content of a non-probabilistic sample of advertising images (N = 150). Differences were identified in the use of the colors green (p = 0.04) and red (p = 0.01), but not in the use of the color blue (p = 0.64), suggesting that induction of feelings of pleasantness resulting from the use of the color blue may be associated with the advertising in the alcohol and tobacco industries. Regarding the position of the commercial stimuli, a predominance of the use of quadrants 'C' (p = 0.00) and 'D' (p = 0.01) was found in all three industries, indicating a similar use of areas perceived as being 'heavier'. As to the size, 78% of advertisements placed the commercial stimuli within a range of 0-25% of the total image. The results showed some similarities in the use of visuoperceptual content in advertisements for tobacco, alcohol and food, especially between tobacco and alcohol. The article offers a convergence analysis of these three industries altogether, providing additional subsidies for the formulation of protection policies. © The Author 2015.

    Amino acid imaging is increasingly being used for assessment of brain tumor malignancy, extent of disease, and prognosis. This study explores the relationship between proliferative activity, amino acid transport, and glucose metabolism in three glioma cell lines (U87, Hs683, C6) at different phases of growth in culture. Growth phase was characterized by direct cell counting, proliferation index determined by flow cytometry, and [ 3 H]thymidine (TdR) accumulation, and was compared with the uptake of two non-metabolized amino acids ([ 14 C]aminocyclopentane carboxylic acid (ACPC) and [ 14 C]aminoisobutyric acid (AIB)), and [ 18 F]fluorodeoxyglucose (FDG). Highly significant relationships between cell number (density), proliferation index, and TdR accumulation rate were observed in all cell lines (r>0.99). Influx (K 1 ) of both ACPC and AIB was directly related to cell density, and inversely related to the proliferation index and TdR accumulation in all cell lines. The volume of distribution (V d ) for ACPC and AIB was lowest during rapid growth and highest during the near-plateau growth phase in all cell lines. FDG accumulation in Hs683 and C6 cells was unaffected by proliferation rate, growth phase, and cell density, whereas FDG accumulation was correlated with TdR accumulation, growth phase, and cell density in U87 cells. This study demonstrates that proliferation rate and glucose metabolism are not necessarily co-related in all glioma cell lines. The values of K 1 and V d for ACPC and AIB under different growth conditions suggest that these tumor cell lines can up-regulate amino acid transporters in their cell membranes when their growth conditions become adverse and less than optimal.

    Rapid prototyping (RP) is used widely in dental and faciomaxillary surgery with anecdotal uses in orthopedics. The purview of RP in orthopedics is vast. However, there is no error analysis reported in the literature on bone models generated using office-based RP. This study evaluates the accuracy of fused deposition modeling (FDM) using standard tessellation language (STL) files and errors generated during the fabrication of bone models. Nine dry bones were selected and were computed tomography (CT) scanned. STL files were procured from the CT scans and three-dimensional (3D) models of the bones were printed using our in-house FDM based 3D printer using Acrylonitrile Butadiene Styrene (ABS) filament. Measurements were made on the bone and 3D models according to data collection procedures for forensic skeletal material. Statistical analysis was performed to establish interobserver co-relation for measurements on dry bones and the 3D bone models. Statistical analysis was performed using SPSS version 13.0 software to analyze the collected data. The inter-observer reliability was established using intra-class coefficient for both the dry bones and the 3D models. The mean of absolute difference is 0.4 that is very minimal. The 3D models are comparable to the dry bones. STL file dependent FDM using ABS material produces near-anatomical 3D models. The high 3D accuracy hold a promise in the clinical scenario for preoperative planning, mock surgery, and choice of implants and prostheses, especially in complicated acetabular trauma and complex hip surgeries.

    Full Text Available Background: Sleep is an essential element for adolescent mental and physical growth and development, but today′s young adolescents are deprived of this. Earlier studies in Europe and America showed pitiable sleep quality of young college students, which affect their academic growth. However, as per our literature search there is a lack of such studies in Indian context especially, within pharmacy education. Objective: The present study was designed to investigate the interrelation between the demographic characteristics, life-style, and academic progress with sleep quality and sleep problems along with daytime and nighttime habits in young female pharmacy students of India. Materials and Methods: Questionnaire on sleep and daytime habits (QS and DH was prepared. Our sample survey consists of 226 female pharmacy students of Banasthali University. QS and DH of multiple choice type, covered demographic characteristic (3 questions sleep and daytime habits (25 questions, life-style and academic progress (3 questions, and one question of course curriculum. Parameters were co-related by point scale method using the SPSS 16.0 software. Results: Data derived and analyze from survey illustrated that quality of sleep was as: Excellent - 20.4%, good - 38.5%, satisfactory - 35.8%, poor - 4%, and very poor - 1.3% of participants. Living condition (ρ=0.168, P =0.011, academic progress (ρ=0.151, P=0.023, leisure activity (ρ=0.133, P<0.05, and daytime naps (ρ=0.160, P=0.016 were significantly correlated with sleep quality. In addition, daytime sleepiness caused a significant problem for students and created a number of sleep disorders. Nevertheless, Sleep quality was not associated with age, body mass index, and coffee in the late evening. Conclusion: Study reported that sleep associated problems were common complaints in female pharmacy students.

    Hras (v-Ha-ras Harvey rat sarcoma viral oncogene homolog) plays a pivotal role in breast tumorigenesis. Expressional aberrations in Hras has significantly been correlated with patient's poor overall survival. In the present study, in silico characterization of Hras to trigger downstream effectors including raf, mek, erk has been explored. Three mutational hotspots for Hras (condons12, 13, 61) have been retrieved from the literature. Promoter modelling using Proscan software revealed a promoter region lacking TATA sequence. To study the epigenetic modifications, methylation analysis of promoter lacking TATA box was done using Methylator software. Methylation is directly correlated with tumor targeting therapies as it represses expression of certain oncogenes. Five candidate sites for hypermethylation of Hras were predicted. Analysis of protein residues involved in interlocking with its downstream effector proteins was also uncovered. In addition to this, a diagnostic and therapeutic relevance of micro RNAs (miRNAs/miRs) specifically acting either as oncogene or tumor suppressors on Hras mediated pathway have been identified. Seven micro RNAs (Let-7, miR-195, miR-497, miR-184, miR-34a, miR-34c, miR-155) found to be responsible for down regulating expression of proteins involved in ressignalling cascade while miR-372 and miR373, miR-212, miR206/21 and miR-17-92 cluster are known to elevate rassignalling pathway. Interestingly, dysregulated expression of Let-7, miR-195, miR-497, miR-184, miR-34, miR-155 co-related with poor prognosis in different cancers has also supported these in silico findings. (author)

    Full Text Available Objectives: To estimate the usefulness of the Indian diabetes risk score for detecting undiagnosed diabetes in the rural area of Tamil Nadu. Materials and Methods: The present study was conducted in the field practice area of rural health centers (Chunampett and Annechikuppam, Tamil Nadu, covering a population of 35000 from February to March 2008 by using a predesigned and pretested protocol to find out the prevalence and the risk of diabetes mellitus in general population by using Indian diabetes risk score. Results: 1936 respondents comprising 1167 (60.27% females and 769 (39.73% males were studied. Majority 1203 (62.50% were Hindus. 1220 (63.% had studied up to higher secondary. 1200 (62% belonged to lower and lower-middle socio-economic class. A large number of the subjects 948 (50% were below 35 years of age. Most of the respondents 1411 (73% indulged in mild to moderate physical activity. 1715 (87.91% had no family history of diabetes mellitus. 750 (39.64% individuals were in the overweight category (>25 BMI. Out of these overweight persons, 64% had high diabetic risk score. It is observed that chances of high diabetic score increase with the increase in BMI. Prevalence of diabetes in studied population was 5.99%; out of these, 56% known cases of diabetes mellitus had high (>60 IDRS. Co-relation between BMI and IDRS shows that, if BMI increases from less than 18.50 to more than 30, chances of high risk for developing diabetes mellitus also significantly increase. Conclusion: This study estimates the usefulness of simplified Indian diabetes risk score for identifying undiagnosed high risk diabetic subjects in India. This simplified diabetes risk score has categorized the risk factors based on their severity. Use of the IDRS can make mass screening for undiagnosed diabetes in India more cost effective.

    Full Text Available Background: Shirodhara is a classical and a well-established ayurvedic procedure of slowly and steadily dripping medicated oil or other liquids on the forehead. This procedure induces a relaxed state of awareness that results in a dynamic psycho-somatic balance. Objectives: The objective of the study is to evaluate the psychological and physiological effects of Shirodhara in healthy volunteers by monitoring the rating of mood and levels of stress, electrocardiogram (ECG, electroencephalogram (EEG, and selected biochemical markers of stress. Materials and Methods: The study was conducted in the human pharmacology laboratory. The study design was open labeled, comparing the baseline variables with values after Shirodhara. The subjects (n = 16 chosen were healthy human volunteers who gave an informed consent. Shirodhara was preceded by Abhyanga - whole body massage. The Shirodhara method was standardized for rate of dripping with peristaltic pump and temperature was controlled with a thermostat. Mood and stress levels were assessed by validated rating scales. The pre- and post-Shirodhara ECG and EEG records were evaluated. Results: Student′s paired "t" test was applied to the means + SE of the variables to calculate statistical significance at P <0.05. There was a significant improvement in mood scores and the level of stress (P <0.001. These changes were accompanied by significant decrease in rate of breathing and reduction in diastolic blood pressure along with reduction in heart rate. The relaxed alert state, after Shirodhara, was co-related with an increase in alfa rhythm in EEG. Conclusion : A standardized Shirodhara leads to a state of alert calmness similar to the relaxation response observed in meditation. The clinical benefits observed with Shirodhara in anxiety neurosis, hypertension, and stress aggravation due to chronic degenerative diseases could be mediated through these adaptive physiological effects.

    Objective This study has two aims: 1) to evaluate the apical transportation of the Wizard CD Plus and ProTaper Universal after preparation of simulated root canals; 2) to compare, with Adobe Photoshop, the ability of a new software (Regeemy) in superposing and subtracting images. Material and Methods Twenty five simulated root canals in acrylic-resin blocks (with 20º curvature) underwent cone beam computed tomography before and after preparation with the rotary systems (70 kVp, 4 mA, 10 s and with the 8×8 cm FoV selection). Canals were prepared up to F2 (ProTaper) and 24.04 (Wizard CD Plus) instruments and the working length was established to 15 mm. The tomographic images were imported into iCAT Vision software and CorelDraw for standardization. The superposition of pre- and post-instrumentation images from both systems was performed using Regeemy and Adobe Photoshop. The apical transportation was measured in millimetres using Image J. Five acrylic resin blocks were used to validate the superposition achieved by the software. Student's t-test for independent samples was used to evaluate the apical transportation achieved by the rotary systems using each software individually. Student's t-test for paired samples was used to compare the ability of each software in superposing and subtracting images from one rotary system per time. Results The values obtained with Regeemy and Adobe Photoshop were similar to rotary systems (P>0.05). ProTaper Universal and Wizard CD Plus promoted similar apical transportation regardless of the software used for image's superposition and subtraction (P>0.05). Conclusion Wizard CD Plus and ProTaper Universal promoted little apical transportation. Regeemy consists in a feasible software to superpose and subtract images and appears to be an alternative to Adobe Photoshop. PMID:24212994

    Full Text Available EPA (Eicosapentaenoic acid and DHA (Docosahexaenoic acid content in common fresh water fish : mujahir (Oreochromis mossambicus after indirect heating were analysed. The aims of this study were to determine the effect of indirect heating process and α-tocopherol additions on both fatty acid stability.Lipids content in the mujahir fillets were extracted by Folch method using chloroform-metanol (2:1 mixture. Fatty acids in fish oil were converted to fatty acid methyl esters and then injected into gas chromatography to determine the EPA and DHA concentration. Operating condition of gas chromatography were programmed as follows: injection port temperature at 270 oC, detector at 280 oC, initial column temperature at 200 oC, and the final at 280 oC, the carrier gas was helium with flow rate of 10 ml per minute and temperature of column was increased gradually at 10 oC per minute. The effect of α-tocopherol addition on the stability of EPA and DHA was studied by adding α-tocopherol at 50 to 200 mg per kilogram sample before indirect heating process was carried out.The analysis of mujahir fish oil showed that the content of EPA and DHA in 100 grams fresh sample was 105 and 406,5 mg respectivelly. Indirect heating caused the EPA and DHA content decreased significantly. The addition of α-tocopherol results in a positive corelation between α-tocopherol concentration added and the decrease of EPA and DHA content during the heating process.   Keywords: fatty acid, eicosapentaenoic acid, docosahexaenoic acid

    The present study concerns the enhancement of methanol selectivity of three dimensional (3D) nanoflowers (NFs) of ZnO by dispersing nickel oxide (NiO) and palladium oxide (PdO) nanoparticles on the surface of the nanoflowers to form localized hybrid nano-junctions. The nanoflowers were fabricated through a liquid phase deposition technique and the modification was achieved by addition of NiCl and PdCl2 solutions. In addition to the detailed structural (like X-ray diffraction (XRD), electron dispersive spectroscopy (EDS), X-ray mapping, XPS) and morphological characterization (by field emission scanning electron microscopy (FESEM)), the existence of different defect states (viz. oxygen vacancy) was also confirmed by photoluminescence (PL) spectroscopy. The sensing properties of the pristine and metal oxide nanoparticle (NiO/PdO)-ZnO NF hybrid sensor structures, towards different alcohol vapors (methanol, ethanol, 2-propanol) were investigated in the concentration range of 0.5-700 ppm at 100-350 °C. Methanol selectivity study against other interfering species, viz. ethanol, 2-propanol, acetone, benzene, xylene and toluene was also investigated. It was found that the PdO-ZnO NF hybrid system offered enhanced selectivity towards methanol at low temperature (150 °C) compared to the NiO-ZnO NF and pristine ZnO NF counterparts. The underlying mechanism for such improvement has been discussed with respective energy band diagram and preferential dissociation of target species on such 3D hybrid structures. The corresponding improvement in transient characteristics has also been co-related with the proposed model.

    The B-site ordered double perovskite oxides LaPbMSbO 6 (M=Co, Ni) have been synthesized via the modified Sol–Gel precursor two-step route. Rietveld refinements reveal strong abnormal structural distortion and BO 6 octahedral deformation appearing along the ab plane. Owing to the cooperative Jahn–Teller effect of Co 2+ and Pb 2+ ions, the Co-related compound exhibits almost complete Co 2+ –Sb 5+ order. For magnetic properties, spin-canted antiferromagnetic state with high extent of magnetic frustration is confirmed. The Ni-related compound presents heavier magnetic frustration for introducing tiny disorder on site occupation accompanied with valence state and further enhancing the complexity of magnetic competition. Dielectric measurements present a considerable temperature dependent dielectric relaxation with great dc-like loss feature in the LaPbCoSbO 6 . For LaPbNiSbO 6 , however, the permittivity with low dielectric loss is shown to be insensitive to either temperature or frequency. The corresponding electronic active energy manifests that the weakly bounded 3d-electron is prone to hop in a more distorted Co–Sb sublattice. - Graphical abstract: XRD Rietveld refinement result of LaPbCoSbO 6 presented a large BO 6 octahedral distortion along the ab plane. Based upon the variations from Co–O–Sb bond angles, a fierce competition from many extended magnetic coupling routes (M–O–O–M) would induce a considerably large magnetic frustration and electron hopping restriction. - Highlights: • Highly ordered LaPbMSbO 6 (M=Co, Ni) were synthesized. • Abnormal structural distortion appeared in the ab plane. • Strong magnetic frustration was confirmed via M 2+ –O–O–M 2+ route. • Dielectric measurements presented a large difference between Co and Ni samples. • 3d-electronic structure determines lattice distortion and physical properties

    Understanding and controlling natural and synthetic biointerfaces is known to be the key to a wide variety of application within cell culture and tissue engineering field. As both material characteristics and methods are important in tailoring biointerfaces characteristics, in this work we explore the feasibility of using Matrix Assisted Pulsed Laser Evaporation technique for obtaining synthetic copolymeric biocoatings (i.e. poly(ethylene glycol)-block-poly(ε-caprolactone) methyl ether) for evaluating in vitro Vero and MC3T3-E1 pre-osteoblasts cell response. Characterization and evaluation of the coated substrates were carried out using different techniques. The Fourier transform infrared spectroscopy data demonstrated that the main functional groups in the MAPLE-deposited films remained intact. Atomic Force Microscopy images showed the coatings to be continuous, with the surface roughness depending on the deposition parameters. Moreover, the behaviour of the coatings in medium mimicking the pH and temperature of the human body was studied and corelated to degradation. Spectro-ellipsometry (SE) and AFM measurements revealed the degradation trend during immersion time by the changes in coating thickness and roughness. In vitro biocompatibility was studied by indirect contact tests on Vero cells in accordance with ISO 10993-5/2009. The results obtained in terms of cell morphology (phase contrast microscopy) and cytotoxicity (LDH and MTT assays) proved biocompatibility. Furthermore, direct contact assays on MC3T3-E1 pre-osteoblasts demonstrated the capacity of all analyzed specimens to support cell adhesion, normal cellular morphology and growth.

    Full Text Available Background: Rapid prototyping (RP is used widely in dental and faciomaxillary surgery with anecdotal uses in orthopedics. The purview of RP in orthopedics is vast. However, there is no error analysis reported in the literature on bone models generated using office-based RP. This study evaluates the accuracy of fused deposition modeling (FDM using standard tessellation language (STL files and errors generated during the fabrication of bone models. Materials and Methods: Nine dry bones were selected and were computed tomography (CT scanned. STL files were procured from the CT scans and three-dimensional (3D models of the bones were printed using our in-house FDM based 3D printer using Acrylonitrile Butadiene Styrene (ABS filament. Measurements were made on the bone and 3D models according to data collection procedures for forensic skeletal material. Statistical analysis was performed to establish interobserver co-relation for measurements on dry bones and the 3D bone models. Statistical analysis was performed using SPSS version 13.0 software to analyze the collected data. Results: The inter-observer reliability was established using intra-class coefficient for both the dry bones and the 3D models. The mean of absolute difference is 0.4 that is very minimal. The 3D models are comparable to the dry bones. Conclusions: STL file dependent FDM using ABS material produces near-anatomical 3D models. The high 3D accuracy hold a promise in the clinical scenario for preoperative planning, mock surgery, and choice of implants and prostheses, especially in complicated acetabular trauma and complex hip surgeries.

    To determine the shaping ability and cleaning efficiency of hand K-flexofiles, ProTaper, LightSpeed and Mtwo instruments during the preparation of curved root canals in extracted human teeth. A total of 120 root canals of mandibular and maxillary molars with curvature more than 20° were divided into four groups of 30 each. In group A, canals were prepared using hand K-flexofiles following the crown down technique. In group B LightSpeed, in group C ProTaper, and in group D Mtwo rotary instruments were used to prepare the root canals. Using pre- and post-instrumentation radiographs, straightening of the canal curvature was determined with Corel Draw 9.0 software tools. The amount of debris and smear layer were quantified at three different areas (coronal, middle, and apical thirds) of root canal using SEM. The collected data were analyzed statistically using Student's paired 't' test. The mean change in curvature for hand K-files was 7.71°, for ProTaper files 6.03°, for Mtwo 5.43°, and for LightSpeed instruments were found to be 4.57°. The percentage change in the curvature for all the four groups was statistically highly significant (PProTaper (65.48%) followed by Mtwo (66.22%), LightSpeed (71.67%) and the maximum with hand K-files (74.16%). However, the difference in mean leftover debris between ProTaper and Mtwo was not significant. ProTaper and Mtwo resulted in good cleaning, and LightSpeed maintained the original canal curvature better than the ProTaper, Mtwo, or Hand K-files.

    Full Text Available Despite the proclaimed revival of the industrial policy, state aid granted by the EU still remain at a concerning low level. This may be explained by EU’s unique institutional achitecture, that allows the European Commission to monitor and restrict state aid related activities in the member states. Relying on 2007 –2013 statistical data published by Eurostat, AMECO and OCDE data bases, the main purpose of this paper refers to determining the corelation between state aid authorised by the European Comission for Romania and some selected member states and their competitiveness level, in the period 2007 – 2013. Even if the member states government would know which industry of company should br supported, the actual allocation of the public fund is strongly influenced by legitime interests. Therefor, state aid allocation is usualy dependent on political considerations and on the negotiation power of the involved parties, rather than on economic objectives. The main purose of this paper is the following: firstly to determine the relation State Ais – Competitiveness, analysing the cases of Romania, Germany, France, Austria and Poland between 2007 and 2013; and secondly t determine if there is a measurable impact at national level, and to identify new growth possibilities of state aid efficiency. Our main hypothesys is analysed with the help of an original system consisting in competitiveness agregated indicators and their corespondents from the state aid field, and the results obtained are graphicaly presented. This paper is based on the research for the PhD thesis entitled Competition versus competitineness. State aid impact in Romania in the context of EU integration context

    Body mass index (BMI) is an index that measures height for weight, which is commonly used to categorize underweight, overweight, and obese individuals. Deviation from normal weight results from an imbalance between caloric consumption and energy expenditure. Childhood obesity and childhood dental caries are coincidental in many populations, probably due to common confounding risk factors, such as intake frequency, cariogenic diet, and poor oral hygiene. So the aim of the present study was to assess the BMI status and to corelate between dental caries and BMI among the Anganwadi children of Belgaum city, Karnataka, India. Four hundred and thirty three children from 20 Anganwadi's belonging to the age group of 2 to 6 years of both sexes were measured for BMI and dental caries status. The caries index was measured as the number of decayed (d) and filled (f) teeth (t) (dft). The BMI in units of kg/m 2 was determined and children were categorized according to age-and gender-specific criteria as underweight (95th percentile). The data were subjected to statistical analysis using Student's t-test, analysis of variance (ANOVA), and Karl Pearson's correlation coefficient test with the help of Statistical Package for the Social Sciences (SPSS) version 18.0. The proportion of subjects in Centre for Disease Control (CDC) weight categories was: 5% underweight, 79% normal, 9% under the risk for overweight, and 6% overweight. A significant association was found between children with normal BMI and those who were underweight, overweight, and under the risk for overweight. Children with overweight/obese or underweight/malnourished children had higher decayed and filled surfaces compared to children with normal weight. Nutritional status has a profound effect on dental caries. Both underweight/malnutrition and overweight/ obesity have significant adverse implications for health. Childhood obesity and childhood dental caries are coincidental in many populations.

    To investigate the electro-optical properties of indium antimonide (InSb) for photo-voltaic applications, we performed first principles calculations using density functional theory (DFT). Our DFT calculations are based on full potential linearized augmented plane wave (FP-LAPW) method implemented by WIEN2K code. These calculations are carried out using generalized gradient approximation (GGA) and Tran Blaha modified Becke Johnson (TB-mBJ) approximation for exchange co-relation potential. All the calculations are performed with and without the addition of spin-orbit interaction (SOI) to GGA and TB-mBJ potentials. Addition of SOI gives the results very close to their experimental values and makes the calculations independent of k-points consideration. All the results are calculated by considering the temperature as high as 300 K. To the best of our knowledge, all the previously published theoretical results were calculated at 0 K and no such results have been reported at 300 K. In this article, we are reporting band structure, density of states (DOS) and the band gap dependent optical properties of InSb. The calculated direct band gap is 0.17 eV, refractive index is 3.79 and extinction coefficient as 3.22. - Highlights: • Room temperature calculations of electro-optical properties of InSb. • Effect of SOI on the band structure and critical points. • The addition of SOI made the calculation k-points independent. • Optical properties were calculated without broadening or applying scissor potential.

    Cohesion between sister chromatids is mediated by cohesin and is essential for proper meiotic segregation of both sister chromatids and homologs. solo encodes a Drosophila meiosis-specific cohesion protein with no apparent sequence homology to cohesins that is required in male meiosis for centromere cohesion, proper orientation of sister centromeres and centromere enrichment of the cohesin subunit SMC1. In this study, we show that solo is involved in multiple aspects of meiosis in female Drosophila. Null mutations in solo caused the following phenotypes: 1) high frequencies of homolog and sister chromatid nondisjunction (NDJ) and sharply reduced frequencies of homolog exchange; 2) reduced transmission of a ring-X chromosome, an indicator of elevated frequencies of sister chromatid exchange (SCE); 3) premature loss of centromere pairing and cohesion during prophase I, as indicated by elevated foci counts of the centromere protein CID; 4) instability of the lateral elements (LE)s and central regions of synaptonemal complexes (SCs), as indicated by fragmented and spotty staining of the chromosome core/LE component SMC1 and the transverse filament protein C(3)G, respectively, at all stages of pachytene. SOLO and SMC1 are both enriched on centromeres throughout prophase I, co-align along the lateral elements of SCs and reciprocally co-immunoprecipitate from ovarian protein extracts. Our studies demonstrate that SOLO is closely associated with meiotic cohesin and required both for enrichment of cohesin on centromeres and stable assembly of cohesin into chromosome cores. These events underlie and are required for stable cohesion of centromeres, synapsis of homologous chromosomes, and a recombination mechanism that suppresses SCE to preferentially generate homolog crossovers (homolog bias). We propose that SOLO is a subunit of a specialized meiotic cohesin complex that mediates both centromeric and axial arm cohesion and promotes homolog bias as a component of chromosome

    Case-oriented small group discussions (COSGDs) can help students to correlate and integrate the basic science of dental materials into clinical application. We used COSGDs along with didactic lectures in dental material curriculum and hypothesized that case-oriented group discussions would be more effective than traditional lecture alone in terms of performance of students, student perception on the above two teaching methodologies and the feasibility in classes of 2010, 2011 and 2012. A total of 170 students were taught using both COSGD and didactic lecture in a randomized controlled crossover trial design. Their performance was assessed through multiple-choice questions (MCQs) as part of the formative assessment, and their perception was assessed through Likert scale questionnaire. The mean difference in the scores between case-oriented group discussions with lecture and didactic lecture showed significant difference only in few topics. Around 94-96% of students perceived COSGD with didactic lecture help them understand theory better; 76-92% of students feel more comfortable asking questions in a group discussion; 89-98% of students feel such discussions motivate them and 91-100% of students agree that discussions make the subject interesting in the respective years of 2010, 2011 and 2012. Effectiveness of COSGD in terms of scores through MCQs is comparable to traditional lecture. However, most of the students perceive COSGD help them understand the theory better; co-relate clinically; more motivating and interesting than a traditional lecture. Feasibility in institution needs more time and resources to conduct COSGD within the dental material curriculum.

    Vascular risk factors may play an important role in the pathophysiology of Alzheimer's disease (AD). While there is consistent evidence of gray matter (GM) abnormalities in earlier stages of AD, the presence of more subtle GM changes associated with vascular risk factors in the absence of clinically significant vascular events has been scarcely investigated. This study aimed to examine GM changes in elderly subjects with cardiovascular risk factors. We predicted that the presence of cardiovascular risk would be associated with GM abnormalities involving the temporal-parietal cortices and limbic structures. We recruited 248 dementia-free subjects, age range 66-75 years, from the population-based "São Paulo Ageing and Health Study", classified in accordance to their Framingham Coronary Heart Disease Risk (FCHDR) score to undergo an MRI scan. We performed an overall analysis of covariance, controlled to total GM and APOE4 status, to investigate the presence of regional GM abnormalities in association with FCHDR subgroups (high-risk, medium-risk, and low-risk), and followed by post hoc t-test. We also applied a co-relational design in order to investigate the presence of linear progression of the GM vulnerability in association with cardiovascular risk factor. Voxel-based morphometry showed that the presence of cardiovascular risk factors were associated with regional GM loss involving the temporal cortices bilaterally. Those results retained statistical significance after including APOE4 as a covariate of interest. We also observed that there was a negative correlation between FCHDR scores and rGM distribution in the parietal cortex. Subclinical cerebrovascular abnormalities involving GM loss may provide an important link between cardiovascular risk factors and AD.

    This study was undertaken to investigate the frequency of intestinal accumulation of Tc-99m 3, 3-diphosphono-1, 2-propanedicarboxylic acid (DPD) on bone scans, describe the patterns of intestinal Tc-99m DPD uptake and discuss the possible mechanisms of this unusual finding. Three thousand, one hundred and ninety-four consecutive patients have been evaluated for intestinal Tc-99m DPD uptake on bone scans. A whole-body bone scan and various spot views were obtained to evaluate the location and intensity of intestinal uptake. Delayed scan and SPECT study were performed to define characteristics of intestinal uptake in some of patients. Available reports of co-relative radiologic imaging, endoscopic studies and laboratory tests were also reviewed to explain the intestinal uptake. Eighteen (9 female, 9 male) patients out of 3194 with a mean age of 57 years showed intestinal Tc-99m DPD uptake. The locations of intestinal uptake were well dispersed throughout the abdomen. The majority of the cases showed lower intensity than iliac spine (12/18, 67%). Eight patients didn't show significant change of uptake characteristics on the delayed images, while intestinal uptake traveled distally in nine patients. Two cases were revealed uptake of peritoneal carcinomatosis with small amount ascites and three cases were revealed tumoral uptake of intestine. Four patients with gastritis showed similar characteristic of intestinal uptake. Six cases of distally traveled intestinal uptake suggested intraluminal Tc-99m DPD activity such as gastrointestinal bleeding. However, stool occult blood tests were negative in three patients, and there is no clinical evidence of gastrointestinal bleeding in other three patients. Intestinal Tc-99m DPD uptake can be observed in 0.5% of bone scans. The mechanism of intestinal uptake is still unclear in some of the patients. Delayed imaging additional spot views and SPECT studies help in the differentiation of this finding from possible

    Full Text Available ABSTRACT: Introduction & Objective: Sexualy transmitted infections (STIs and AIDS are the most common diseases worldwide. Women are more affected by STIs and AIDS due to gender-related factors such as biological, cultural and so on. This study was conducted to investigate knowledge about AIDS and STIs among married women in Kohgilouyeh & BoyerAhmad Province/Iran. Materials & Methods: This cross-sectional study was conducted in the urban areas of Kohgilouyeh and Boyerahmad province. Using stratifed cluster sampling, a valid questionnaire covering demographic variables and items related to knowledge about AIDS and STIs was administered to 1379 women covered by the urban PHC clinics. Results: The mean age of the respondents was 33.3 (SD=±9.3. Most were household (%85 and the mean level of their formal education was 7.2 years (SD=±4.8. The results also showed that women had the most knowledge with the statements that "using condom protects against AIDS" (%63.9 and "asymptomatic persons would be as AIDS vectors" (%65.1. There was a significant relation between education and recognizing AIDS as a sexualy transmitted infection (p=0.004. Albeit, women were poorly familiar with the STIs, the most knowledge was found with gonorrhea (%40.5 and the least with chlamydia (%12.2. The most knowledge was observed with the statements that "STIs would induce PID in women" and "using condom protects against all the venereal diseases" (both %61.1. A significant corelation was found between education and job and fimiliarity with STIs (p<0.001. Conclusion: Findings showed limited knowledge on sexualy transmitted infections and fairely good knowledge on AIDS. There is need for the promotion of women's knowledge in sexual health field.

    There is no standardized method for assessing vitiligo. In this article, we review the literature from 1981 to 2011 on different vitiligo assessment methods. We aim to classify the techniques available for vitiligo assessment as subjective, semi-objective or objective; microscopic or macroscopic; and as based on morphometry or colorimetry. Macroscopic morphological measurements include visual assessment, photography in natural or ultraviolet light, photography with computerized image analysis and tristimulus colorimetry or spectrophotometry. Non-invasive micromorphological methods include confocal laser microscopy (CLM). Subjective methods include clinical evaluation by a dermatologist and a vitiligo disease activity score. Semi-objective methods include the Vitiligo Area Scoring Index (VASI) and point-counting methods. Objective methods include software-based image analysis, tristimulus colorimetry, spectrophotometry and CLM. Morphometry is the measurement of the vitiliginous surface area, whereas colorimetry quantitatively analyses skin colour changes caused by erythema or pigment. Most methods involve morphometry, except for the chromameter method, which assesses colorimetry. Some image analysis software programs can assess both morphometry and colorimetry. The details of these programs (Corel Draw, Image Pro Plus, AutoCad and Photoshop) are discussed in the review. Reflectance confocal microscopy provides real-time images and has great potential for the non-invasive assessment of pigmentary lesions. In conclusion, there is no single best method for assessing vitiligo. This review revealed that VASI, the rule of nine and Wood's lamp are likely to be the best techniques available for assessing the degree of pigmentary lesions and measuring the extent and progression of vitiligo in the clinic and in clinical trials. © 2012 The Authors.

    Full Text Available The common usages of elastomeric components in oil and gas field applications are in dynamic atmospheres; especially sealing appliances that are in relative motion when interacting with surfaces. Therefore, their performance and service life mainly depend on the wear and friction characteristics in use. The objective of this scientific work is to identify the effect of swelling-induced ageing on the tribological properties and surface damage mechanisms of hydrogenated nitrile butadiene rubber (HNBR in contact with different liquids. Furthermore, the investigation of the co-relation between mechanical properties and surface properties in the tested conditions is indispensable. In the swollen state, deteriorated mechanical properties were observed; however, in de-swollen conditions, the mechanical properties were restored. As far as the surface characterization is concerned, when the HNBR was swollen by a standard IRM 903 solvent, its wear was greater compared with the un-swollen specimen (1.1 times despite the lower coefficient of friction (COF (reduced by ~25% and surface temperature (reduced by ~2.4 °C. In the de-swollen condition, wear was even greater (6 times, but the COF and surface temperature were situated in between those recorded in the swollen and un-swollen conditions. With swelling, greater wear damage and lower COF were observed; higher surface ageing (softness, which eases crack growth, created bigger debris. Under the conditions used, in the de-swollen states, the bulk mechanical properties were almost recovered, in contrast to the surface properties, which were still significantly impaired.

    Full Text Available Background:peptic ulcers were earlier believed to be caused by dietary factors, gastric acid, and stress. However, in 1983, Warren and Marshall identified the correlation between Helicobacter pylori (H. pylori and peptic ulcers. It is now well established that most of the peptic ulcers occur as a result of H. pylori infection. But the co-relation between perforated peptic ulcer and H. pylori infection is not yet fully established. Aims and objectives : to study the prevalence of H. pylori infection in patients with perforated peptic ulcer. Materials and methods: this was a prospective study carried out in all cases of perforated peptic ulcer reporting in surgical wards of a medical college during 2008-2010. A total of 50 cases, presenting as acute perforation of duodenum and stomach during this period, formed the study group. After resuscitation, all the cases were subjected to emergency exploratory laparotomy. The exact site of perforation was identified, biopsy was taken from the ulcer margin from 2-3 sites and the tissue was sent for H. pylori culture and histopathological examination. Simple closure of perforation, omentoplasty, thorough peritoneal lavage and drainage was carried out. Results: out of the 50 cases of perforated peptic ulcer, 38 happened to be males, and only 12 were females. The age of the patients ranged from 20 to 70 years. All the patients underwent only emergency laparotomy. As many as 46 cases (92% turned out to be positive for H. pylori and only four cases (8% were negative for this infection. Postoperatively, patients who were found to be positive for H. pylori were put on anti-H. pylori treatment. Conclusion: there was a high prevalence of H. pylori infection in patients with perforated gastroduodenal ulcers.

    Bhattacharyya, Nabarun; Bandhopadhyay, Rajib

    Human beings have five senses, namely, vision, hearing, touch, smell and taste. The sensors for vision, hearing and touch have been developed for several years. The need for sensors capable of mimicking the senses of smell and taste have been felt only recently in food industry, environmental monitoring and several industrial applications. In the ever-widening horizon of frontier research in the field of electronics and advanced computing, emergence of electronic nose (E-Nose) and electronic tongue (E-Tongue) have been drawing attention of scientists and technologists for more than a decade. By intelligent integration of multitudes of technologies like chemometrics, microelectronics and advanced soft computing, human olfaction has been successfully mimicked by such new techniques called machine olfaction (Pearce et al. 2002). But the very essence of such research and development efforts has centered on development of customized electronic nose and electronic tongue solutions specific to individual applications. In fact, research trends as of date clearly points to the fact that a machine olfaction system as versatile, universal and broadband as human nose and human tongue may not be feasible in the decades to come. But application specific solutions may definitely be demonstrated and commercialized by modulation in sensor design and fine-tuning the soft computing solutions. This chapter deals with theory, developments of E-Nose and E-Tongue technology and their applications. Also a succinct account of future trends of R&D efforts in this field with an objective of establishing co-relation between machine olfaction and human perception has been included.

    Obstructive sleep apnea syndrome (OSAS) may promote hyperglycemia and insulin resistance. Our aim is to investigate the effect of OSAS on the fasting plasma glucose, glycosylated hemoglobin (HbA1c), and C reactive protein (CRP) in nondiabetic patients. Blood parameters of consecutive 90 non diabetic patients whom polysomnografic evaluations were done in our sleep laboratory was evaluated. Among these 61 patients with normal fasting blood glucose were classified due to their apne-hipopnea index (AHI) as mild (n=16, 26.2%), moderate (n=18, 29.5%) and severe (n=27, 44.2%) OSAS. The fasting plasma glucose, HbA1c and CRP were measured. Mean age of the patients was 47.7±11.2 years, 72% male. HbA1c, fasting glucose levels show positive correlation with BMI (r=.503, P=.00; r=.258, P=.045). No relation of HbA1c to apnea index nor AHI was detected while positive corelation of fasting glucose and CRP was detected (r=.262, P=.042; r=.258, P=.045). HbA1c, fasting glucose and CRP levels show negative correlation with minimum SpO2 levels (by order of r=-.302, P=.018; r=-.368, P=.004; r=-.365, P=.004). HbA1c, fasting glucose levels and CRP levels show positive correlation with mean desaturation index (time duration in which SpO2<90% by pulse oxymeter) (r=.263, P=.041; r=.311, P=.015; r=.283, P=.027). Although no relation in between increased HbA1c or glucose levels and severity of OSAS was detected in nondiabetic OSAS patients, the correlation with the night hypoxia was detected. This could also show the effect of night time hypoxia on glucose metabolism in OSAS patients. Copyright © 2012 SEPAR. Published by Elsevier Espana. All rights reserved.

    The purpose of the present study was to find, if there exists, a co-relation between presence of unerupted mandibular third molar and fracture of mandibular condyle. A retrospective, multicenter study was done collecting the data of all mandibular condyle fractures treated from November 2006 till August 2015. Data was collected from the patient's records and radiographs for the following information: age, sex, etiology of fracture, presence and state of lower third molars, and associated fracture. The results were subjected to statistical analysis. Out of 180 patients of condylar fracture, unerupted third molars were present in 35 (19.44 %) cases compared to 145 (80.55 %) cases of condylar fracture where the unerupted third molars were not present. The difference was statistically significant (p fracture was seen in 4 (11.4 %) cases, bilateral condylar fracture associated with other mandibular fractures in 9 (25.7 %) cases, isolated unilateral condylar fracture in 0 (0.0 %) cases, and unilateral condylar fracture associated with other mandibular fractures in 17 (48.5 %) cases and condylar fracture associated with mid face fractures in 5 (14.2 %) cases. In the unerupted third molar absent group, isolated bilateral condylar fracture was seen in 5 (3.4 %) cases, bilateral condylar fracture associated with other mandibular fractures in 30 (20.6 %) cases, isolated unilateral condylar fracture in 24 (16.5 %) cases, unilateral condylar fracture associated with other mandibular fractures in 73 (50.34 %) cases, and condylar fracture associated with mid face fractures in 13(8.96 %) cases. The difference between the groups was statistically significant (p = 0.032). This study suggests that the fractures of mandibular condylar region have a significantly higher incidence in patients without an unerupted mandibular third molar.

    This study has two aims: 1) to evaluate the apical transportation of the Wizard CD Plus and ProTaper Universal after preparation of simulated root canals; 2) to compare, with Adobe Photoshop, the ability of a new software (Regeemy) in superposing and subtracting images. Twenty five simulated root canals in acrylic-resin blocks (with 20º curvature) underwent cone beam computed tomography before and after preparation with the rotary systems (70 kVp, 4 mA, 10 s and with the 8×8 cm FoV selection). Canals were prepared up to F2 (ProTaper) and 24.04 (Wizard CD Plus) instruments and the working length was established to 15 mm. The tomographic images were imported into iCAT Vision software and CorelDraw for standardization. The superposition of pre- and post-instrumentation images from both systems was performed using Regeemy and Adobe Photoshop. The apical transportation was measured in millimetres using Image J. Five acrylic resin blocks were used to validate the superposition achieved by the software. Student's t-test for independent samples was used to evaluate the apical transportation achieved by the rotary systems using each software individually. Student's t-test for paired samples was used to compare the ability of each software in superposing and subtracting images from one rotary system per time. The values obtained with Regeemy and Adobe Photoshop were similar to rotary systems (P>0.05). ProTaper Universal and Wizard CD Plus promoted similar apical transportation regardless of the software used for image's superposition and subtraction (P>0.05). Wizard CD Plus and ProTaper Universal promoted little apical transportation. Regeemy consists in a feasible software to superpose and subtract images and appears to be an alternative to Adobe Photoshop.

    The objective of this project is to investigate the possibility of applying the Joint Reliability Importance(JRI) of two components to the establishment of system maintenance policy. Components are classified into reliability substitutes and reliability compliments. If the sign of JRI of two components is positive, they are called as reliability compliments. If the sign of JRI of two components is negative, they are called as reliability substitutes. In case of reliability compliments, one component becomes more important as the other one works and in case of reliability substitutes, one component becomes more important as the other one fails. Therefore, when the preventive maintenance is carried out, two components which are reliability substitutes should not be maintained at the same time. Also, when the corrective maintenance is carried out, we not only repair the failed components but pay attention to the functioning components which are reliability substitutes with respect to the failed components. The sign of JRI of any two components in series (parallel) system is positive (negative). Then, what is the sign of any two components in k-out-of-n:G system? This project presents an idea of characterizing the k-out-of-n:G system by calculating the JRI of two components in that system, assuming that reliability of all components are equal. In addition to the JRI of two components, JRI of two gates is introduced in this project. The algorithm to compute the JRI of two gates is presented. Bridge system is considered and the co-relation of two min cut sets is illustrated by using the cut-set representation of bridge system and calculating the JRI of two gates. 28 refs., 20 tabs., 32 figs.

    Ocular trauma is a worldwide cause of visual morbidity, a significant proportion of which occurs in the industrial workplace and includes a spectrum of simple ocular surface foreign bodies, abrasions to devastating perforating injuries causing blindness. Being preventable is of social and medical concern. A prospective case series study, to know the profile of ocular trauma at a hospital caters exclusively to factory employees and their families, to co-relate their demographic and clinical profile and to identify the risk factors. Patients with ocular trauma who presented at ESIC Model hospital, Rajajinagar, Bangalore, from June 2010 to May 2011 were taken a detailed demographic data, nature and cause of injury, time interval between the time of injury and presentation along with any treatment received. Ocular evaluation including visual acuity, anterior and posterior segment findings, intra-ocular pressure and gonio-scopy in closed globe injuries, X-rays for intraocular foreign body, B-scan and CT scan were done. Data analyzed as per the ocular trauma classification group. The rehabilitation undertaken medically or surgically was analyzed. At follow-up, the final best corrected visual acuity was noted. A total of 306 cases of ocular trauma were reported; predominantly in 20-40 year age group (72.2%) and in men (75%). The work place related cases were 50.7%and of these, fall of foreign bodies led the list. Visual prognosis was poorer in road traffic accidents rather than work place injuries owing to higher occurrence of open globe injuries and optic neuropathy. Finally, 11% of injured cases ended up with poor vision. Targeting groups most at risk, providing effective eye protection, and developing workplace safety cultures may together reduce occupational eye injuries.

    To study the relationship between IgG titer of pregnant women and hemolytic disease of newborn(HDN) with different blood groups. Four hundred pregnant women, including pregnant women with type O blood, were selected from May 2014 to January 2015 in our hospital for inspection and a couple of different blood groups, the IgG titer of pregnant women were detected in the inspection process. According to neonatal HDN, newborns were divided into 2 groups: HDN group(85 cases) and non-HDN group(315 cases). The incidence of postpartum neonatal hemolytic disease was tracked and the correlation of IgG titers with HDN were systematically analyzed. In the production and inspection process, the IgG titer in pregnant women was divided into groups. the comparison of HDN incidence rate in 4 groups of IgG titer >64 and IgG titer group showed that the prevalence of ABO hemolytic disease of newborn were 96.9%, 79.6%, 63, 7% and 28.8%, there was a certain correlation of pregnant women IgG titers with ABO hemolytic disease of the newborn, that is, with the increase of IgG titer, the incidence of hemolytic disease of newborns increased in certain degree (r=0.8832), the risk in 4 groups of neonatal HDN was higher than that in IgG titer 64 HDN group. There is a certain corelation between prevalence of ABO-HDN and IgG titer of pregnant women. For these pregnant women, the control of the pregnant women IgG titer has a positive clinical significance to reduce the incidence of hemolytic disease of the newborn.

    An experiment was conducted to study the effect of feeding ammoniated rice straw on ruminal total volatile fatty acid (TVFA) and bacterial production rates. Twelve karan swiss, male, rumen fistulated calves (2-2.5 yrs) were divided in three equal groups. Animals were offered rice straw either untreated (A) or 4 per cent urea+40 per cent moisture treated and ensiled for 30 days (B) or 5 per cent urea+30 per cent moisture treated and ensiled for 30 days (C). Protein requirements were met through concentrate mixture. Levels of NH 3 -N and TCA-precipitable-N in strained rumen liquor (SRL) were significantly higher (20.34±0.022, 63.26±0.81 (B), 20.78±0.41, 64.98±0.87 (C) (mg/100 ml SRL) in groups fed ammoniated ±0.31, 45.94±1.91 mg/100 ml S RL), respectively. The bacterial production rates in the rumen (g/day) were significantly higher in groups B and C as compared to group A. TVFA concentrations (mmole/100 ml SRL ) and TVFA production rates (mmole/d) were also significantly higher in groups B and C as compared to group A. The bacterial production rates were significantly co-related with TVFA, NH 3 -N, TCA precipitable-N concentration in the rumen and ATP production. Multiple regression equations relating bacterial production rates with (i)NH 3 -N and TVFA concentration in the rumen, (ii)NH 3 -N and TVFA production rates and (iii)NH 3 -N and ATP produced were also developed.

    Background: To study the patterns of clinically benign breast disease in females and to co-relate them with the pathological findings. Methods: One hundred females who attended the Surgery Outpatients Department in Indira Gandhi Medical College and Research Institute, Pondicherry, with various forms of benign breast diseases during the period from October 2011 to September 2012, were studied. Early diagnoses by doing a triple assessment like a clinical examination, FNAC or a core needle biopsy and imaging methods like ultrasonography or mammography, were made within 72 hrs from the first consultation. The clinical diagnoses were compared with the cytological or histological findings wherever possible and their accuracies were evaluated. Results: Out of the 100 female patients who were studied, 87 patients who presented with breast lumps and fibroadenoma, accounted for 48% of the cases, which was the highest number of patients. Fibrocystic changes and breast abscesses came next with 18% and 12% cases respectively. We detected 3 cases of proliferative disease with atypia and one case with florid hyperplasia, which had high and low risk factors respectively, for developing invasive carcinoma. The oldest lady of the group who was clinically diagnosed to have benign disease, was detected to have invasive ductal carcinoma. They were treated in our hospital and were advised follow up. Conclusion: Benign breast diseases are common in female patients and fibroadenoma is the commonest of them all. Triple assessment provided a quick diagnosis and it alleviated unnecessary anxiety from the patients about breast cancer. The clinical diagnosis of a breast lump, as confirmed by cytology and histology, was accurate in 91.95 % of the cases. PMID:23634406

    Hyo-Hyoun Seo

    Full Text Available Functional characterization of a defensin, J1-1, was conducted to evaluate its biotechnological potentiality in transgenic pepper plants against the causal agent of anthracnose disease, Colletotrichum gloeosporioides. To determine antifungal activity, J1-1 recombinant protein was generated and tested for the activity against C. gloeosporioides, resulting in 50% inhibition of fungal growth at a protein concentration of 0.1 mg·mL-1. To develop transgenic pepper plants resistant to anthracnose disease, J1-1 cDNA under the control of 35S promoter was introduced into pepper via Agrobacterium-mediated genetic transformation method. Southern and Northern blot analyses confirmed that a single copy of the transgene in selected transgenic plants was normally expressed and also stably transmitted to subsequent generations. The insertion of T-DNA was further analyzed in three independent homozygous lines using inverse PCR, and confirmed the integration of transgene in non-coding region of genomic DNA. Immunoblot results showed that the level of J1-1 proteins, which was not normally accumulated in unripe fruits, accumulated high in transgenic plants but appeared to differ among transgenic lines. Moreover, the expression of jasmonic acid-biosynthetic genes and pathogenesis-related genes were up-regulated in the transgenic lines, which is co-related with the resistance of J1-1 transgenic plants to anthracnose disease. Consequently, the constitutive expression of J1-1 in transgenic pepper plants provided strong resistance to the anthracnose fungus that was associated with highly reduced lesion formation and fungal colonization. These results implied the significance of the antifungal protein, J1-1, as a useful agronomic trait to control fungal disease.

    Motor vehicle emissions have been identified as a major source of particulates. Although the low limits of particulate matter cause a need for a particulate trap in most of the present day diesel engines, the physical and chemical characterization of particles with the measures of size, number, volatility and reactivity etc. is of increasing interest with respect to the regeneration frequency and regeneration efficiency of a particulate trap. Within the Cluster of Excellence ''Tailor-Made Fuels from Biomass (TMFB)'' at RWTH Aachen University, the Institute for Combustion Engines carried out a detailed investigation program to explore the potential of future biofuel candidates for future combustion systems. The experiments for particulate measurements and analysis were conducted on a EURO 6 compliant High Efficiency Diesel Combustion System (HECS) with petroleum based diesel fuel as reference and today's biofuel (i.e. FAME) as well as a potential future biomass derived fuel candidate (i.e. 2-MTHF I DBE), being developed under TMFB approach. Soot samples collected on polycarbonate filters were analyzed using SEM; revealing vital informations regarding particle size distribution. Furthermore, thermophoretic sampling was also performed on copper grids and samples were analyzed using TEM to determine its graphitic micro-structure. In addition, X-Ray diffraction (XRD) measurements were also performed to get further quantitative information regarding crystal lattice parameters and structure of investigated soot. The results indicate more than 90% reduction in the mass and number concentrations of engine out particle emissions using future biomass derived fuel candidate. A good co-relation was observed between TEM micro-structure results and quantitative crystal lattice and structure information obtained from XRD studies, indicating higher reactivity for soot emitted from 2-MTHF/DBE.

    Full Text Available High-performance liquid chromatographic (HPLC and UV spectrophotometric methods were developed and validated for the quantitative determination of amlodipine besylate (AM and benazepril hydrochloride (BZ. Different analytical performance parameters such as linearity, precision, accuracy, specificity, limit of detection (LOD and limit of quantification (LOQ were determined according to International Conference on Harmonization ICH Q2B guidelines. The RP-HPLC method was developed by the isocratic technique on a reversed-phase Shodex C-18 5e column. The retention time for AM and BZ was 4.43 min and 5.70 min respectively. The UV spectrophotometric determinations were performed at 237 nm and 366 nm for AM and at 237 nm for BZ. Correlation between absorbance of AM at 237 nm and 366 nm was established and based on developed correlation equation estimation of BZ at 237 nm was carried out. The linearity of the calibration curves for each analyte in the desired concentration range was good (r2 > 0.999 by both the HPLC and UV methods. The method showed good reproducibility and recovery with percent relative standard deviation less than 5%. Moreover, the accuracy and precision obtained with HPLC co-related well with the UV method which implied that UV spectroscopy can be a cheap, reliable and less time consuming alternative for chromatographic analysis. The proposed methods are highly sensitive, precise and accurate and hence successfully applied for determining the assay and in vitro dissolution of a marketed formulation.

    Full Text Available The Mumbai Metropolitan Region is growing in terms of population, industry, educational and commercial units. The daily requirements of commodities and services by all units have increased fast. Plastic is used extensively for packing, protection and service of various commodities. The use of plastic is much higher by industry and households in region. In Brihan Mumbai Municipal Corporation, the density of population is higher. The concentration of small and large industries is more. Therefore the plastic use is much higher for different purposes. It leads to more waste of plastic. In Ulhasnagar Municipal Corporation, the population and industrial units are less. Therefore plastic waste is less generated. Theaters are generating less plastic waste in metropolitan region. The Brihan Mumbai Municipal Corporation (BMC and municipal corporations in Thane district will continuously generate more plastic waste in future. The Tobit regression model shows that plastic waste is positively co-related and statistically significant with pollution and industry in region. Therefore the comprehensive policies are required to reduce plastic waste. This is because plastic waste is affecting on the health of human being. It also affects negatively on soil, air and water. The entire food supply chain gets affected due to plastic waste. The water logging is common due to plastic waste in region. It chock ups the drainage system and it becomes the ground for mosquitoes. It further leads to dengue, malaria and other diseases in region. Municipal corporations must collect plastic in separate bins and process it. The plastic and e-waste can be utilized for road construction in region. All the policies will certainly help to reduce the plastic waste and maintain the clean environment in region.

    Full Text Available Introduction: Dental treatment is usually a poignant phenomenon for children. Projective scales are preferred over psychometric scales to recognize it, and to obtain the self-report from children. Aims: The aims were to evaluate treatment related fear using a newly developed fear scale for children, fear assessment picture scale (FAPS, and anxiety with colored version of modified facial affective scale (MFAS - three faces along with physiologic responses (pulse rate and oxygen saturation obtained by pulse oximeter before and during pulpectomy procedure. Settings and Design: Total, 60 children of age 6-8 years who were visiting the dental hospital for the first time and needed pulpectomy treatment were selected. Children selected were of sound physical, physiological, and mental condition. Two projective scales were used; one to assess fear - FAPS and to assess anxiety - colored version of MFAS - three faces. These were co-related with the physiological responses (oxygen saturation and pulse rate of children obtained by pulse oximeter before and during the pulpectomy procedure. Statistical Analysis Used: Shapiro-Wilk test, McNemar′s test, Wilcoxon signed ranks test, Kruskal-Wallis test, Mann-Whitney test were applied in the study. Results: The physiological responses showed association with FAPS and MFAS though not significant. However, oxygen saturation with MFAS showed a significant change between "no anxiety" and "some anxiety" as quantified by Kruskal-Wallis test value 6.287, P = 0.043 (<0.05 before pulpectomy procedure. Conclusions: The FAPS can prove to be a pragmatic tool in spotting the fear among young children. This test is easy and fast to apply on children and reduces the chair-side time.

    In patients after a stroke there are variable disorders. These patients often need rehabilitation in more than one area beceause of multiple limitations of the ability to perform everyday activities. The aim of the study was to assess correlations - statistical relationships between observed gait parameters, ADL and hand functions - results of rehabilitation of patients after ischaemic stroke according to the NDTBobath method for adults. The investigated group consisted of 60 patients after ischaemic stroke, who participated in the rehabilitation programme. 10 sessions of the NDT-Bobath therapy were provided in 2 weeks (10 days of the therapy). The calculation of correlations was made based on changes of parameters: Bobath Scale (to assess hand functions), Barthel Index (to assess ADL), gait velocity, cadence and stride lenght. Measurements were performed in every patient twice: on admission (before the therapy) and after last session of the therapy to assess rehabilitation effects. The main statistically relevant corellations observed in the study were as follows: in the whole group of patients: poor and moderate (negative) correlation between changes of gait parameters and Bobath Scale and Barthel Index, moderate and severe (negative) correlation between changes of gait parameters and Bobath Scale and Barthel Index in the group of women, correlation between changes in Bobath Scale and Barthel Index in the group of patients with left side of paresis, (negative) correlation between changes of gait parameters and Bobath Scale in group of patients younger than 68 years, moderate, high and very high correlations between changes in gait parameters in groups of women, men, younger than 68 years and older than 68 years. There have been observed statistically significant and favourable changes in the health status of patients, described by gait parameters, changes in hand functions and ADL. Based on the presented correlations there is an assumption that it is hard to

    Background With continuing identification of novel structured noncoding RNAs, there is an increasing need to create schematic diagrams showing the consensus features of these molecules. RNA structural diagrams are typically made either with general-purpose drawing programs like Adobe Illustrator, or with automated or interactive programs specific to RNA. Unfortunately, the use of applications like Illustrator is extremely time consuming, while existing RNA-specific programs produce figures that are useful, but usually not of the same aesthetic quality as those produced at great cost in Illustrator. Additionally, most existing RNA-specific applications are designed for drawing single RNA molecules, not consensus diagrams. Results We created R2R, a computer program that facilitates the generation of aesthetic and readable drawings of RNA consensus diagrams in a fraction of the time required with general-purpose drawing programs. Since the inference of a consensus RNA structure typically requires a multiple-sequence alignment, the R2R user annotates the alignment with commands directing the layout and annotation of the RNA. R2R creates SVG or PDF output that can be imported into Adobe Illustrator, Inkscape or CorelDRAW. R2R can be used to create consensus sequence and secondary structure models for novel RNA structures or to revise models when new representatives for known RNA classes become available. Although R2R does not currently have a graphical user interface, it has proven useful in our efforts to create 100 schematic models of distinct noncoding RNA classes. Conclusions R2R makes it possible to obtain high-quality drawings of the consensus sequence and structural models of many diverse RNA structures with a more practical amount of effort.

    To describe findings of enhanced power Doppler sonography and DSA in experimentally induced VX2 carcinomas in rabbit thigh and to correlate the imaging findings with the histopathologic features. A total of 30 VX2 carcinomas were implanted in rabbit thigh, and after conventional and enhanced power Doppler sonography and DSA, histopathologic examination was performed. Enhanced power Doppler sonography and DSA, were used to determine the distribution pattern of tumor vascularity; to assess its grade and the percentage of a tumor area occupied by vessels, conventional and enhanced power Doppler sonography, as well as DSA, were used. The grade of necrosis and the development of fibrovascular stroma and capsule were histopathologically determined. The findings of power Doppler sonography were compared with those of DSA and the imaging features were correlated with the histopathologic features. At enhanced power Doppler sonography, the signal was either avascular (n=9), peripheral (n=15) or diffuse (n=6), while at DSA, the corresponding totals were eight, fourteen and eight. There was statistically significant corelation between enhanced power Doppler sonogrpahy and DSA, both in their depiction of the distribution of patterns of tumor vascularity and as regards their findings of grade and percentage of vascular area. As determined by both conventional and enhanced power Doppler sonogrpahy, and by DSA, grade of necrosis and the development of fibrovascular stroma and a capsule correlated with grade and the percentage of vascular area. Experimentally induced VX2 carcinomas in rabbit thigh demonstrated various patterns of tumor vascularity, and the findings of enhanced power Doppler sonography correlated with those of DSA. Tumor vascularity, as demonstrated by two imaging modalities, correlated closely with grade of necrosis and the development of fibrovascular stroma and a capsule, as revealed by histopathologic examination.

    The integrity in most of the engineering structures in influenced by the presence of cracks or crack like defects. These structures fail, even catastrophically if a crack greater than a critically safe size exist. Although most of the optimal designed structures are initially free from critical cracks, sub-critical cracks can lead to failures under cyclic loadings, called fatigue crack growth. It is nearly impractical to prevent sub-critical crack growth in engineering structures particularly in crack sensitive structures like most of the structures in nuclear, aerospace and aeronautical domains. However, it is essential to predict the fatigue crack growth for these structures to preclude the in service failures causing loss of assets. The present research presents an automatic procedure for the prediction of fatigue crack growth in three dimensional engineering structures and the key data for the fracture mechanics based design: the stress intensity factors. Three fold analysis procedures are adopted to investigate the effects of repetitive (cyclic) loadings on the fatigue life of different geometries of aluminum alloy 2219-O. A general purpose Finite Element (FE) Code ANSYS-8.0 is used to predict/estimate the fatigue life of the geometries. Computer codes utilizing the Green's Function are developed to calculate the stress intensity factors. Another code based on superposition technique presented by Shivakumara and Foreman is developed to calculate the fatigue crack growth rate, fatigue life (No. of loading cycles are developed to validate the results and finally full scale laboratory tests are conducted for the comparison of the results. The results showing a close co-relation between the different techniques employed gives the promising feature of the analysis approach for the future work. (author)

    A two damage state variable model is used to describe the softening mechanisms, damage initiation and growth for a low alloy ferritic steel 1/2Cr-1/2Mo-1/4V at 565 and 590 deg. C within the Continuum Damage Mechanics framework. The level of complexity of the constitutive equations and the degree of coupling through damage is high and it is difficult to calibrate values of the constitutive constants without recourse to optimisation techniques. A methodology for the analysis of uni-axial experimental data, coupled with a traditional gradient-based optimisation technique, is presented for the unique determination of the constitutive constants. Two sets of experimental data on parent material are used for inversion purposes: at 565 deg. C, c.f. Cane [Cane BJ. Collaborative programme on the corelation of test data for high temperature design of welded steam pipes. Presentation and analysis of the material data.

C has been deduced by considering the values of constitutive parameters for the same alloy deduced by Perrin and Hayhurst [Perrin IJ, Hayhurst DR.

    Full Text Available Introduction: Adolescent girls belong to vital age group, not only because they are the entrant population to motherhood but also because they are threshold between childhood and motherhood. The girls should be educated about significance of menstruation and development of secondary sexual characteristics, selection of sanitary menstrual absorbent and its proper disposal. Aims and Objectives: The objectives of the present study were to assess the existing knowledge and practice regarding menstrual hygiene among adolescent girls and to determine the co-relation of knowledge and practice score among the adolescent girls. Materials and Methods: The study conducted was a descriptive cross sectional study done on 100 adolescent girls from class 9th to 12th of Govt. Girls School in Shimla, Himachal Pradesh (Convenience sampling. Prior to the commencement of the study, they were explained the purpose and nature of the study. Information on demographic variables which include age, class, type of family, education of mother, family income, age of menarche were collected from the participants. Results: The data on knowledge scores revealed that 29% had adequate knowledge about menstrual hygiene, 71% had inadequate knowledge about menstrual hygiene. The data revealed on practice scores revealed that 19%, 69%, 12% samples had poor, fair and good score of practices regarding menstrual hygiene respectively. Knowledge and practice scores of participants shows positive correlation between the two scores (*P < 0.001. Conclusion: Lack of information about menstrual hygiene can be attributed to various factors which need to be studied separately. The above findings reinforce the need to encourage safe and hygienic practices among the adolescent girls and bring them out of traditional beliefs, misconceptions and restrictions regarding menstruation.

    Dissolved major ions and important heavy metals including total arsenic and iron were measured in groundwater from shallow (25-33 m) and deep (191-318 m) tube-wells in southeastern Bangladesh. These analyses are intended to help describe geochemical processes active in the aquifers and the source and release mechanism of arsenic in sediments for the Meghna Floodplain aquifer. The elevated Cl- and higher proportions of Na+ relative to Ca2+, Mg2+, and K+ in groundwater suggest the influence by a source of Na+ and Cl-. Use of chemical fertilizers may cause higher concentrations of NH 4+ and PO 43- in shallow well samples. In general, most ions are positively correlated with Cl-, with Na+ showing an especially strong correlation with Cl-, indicating that these ions are derived from the same source of saline waters. The relationship between Cl-/HCO 3- ratios and Cl- also shows mixing of fresh groundwater and seawater. Concentrations of dissolved HCO 3- reflect the degree of water-rock interaction in groundwater systems and integrated microbial degradation of organic matter. Mn and Fe-oxyhydroxides are prominent in the clayey subsurface sediment and well known to be strong adsorbents of heavy metals including arsenic. All five shallow well samples had high arsenic concentration that exceeded WHO recommended limit for drinking water. Very low concentrations of SO 42- and NO 3- and high concentrations of dissolved Fe and PO 43- and NH 4+ ions support the reducing condition of subsurface aquifer. Arsenic concentrations demonstrate negative co-relation with the concentrations of SO 42- and NO 3- but correlate weakly with Mo, Fe concentrations and positively with those of P, PO 43- and NH 4+ ions. ?? 2007 Springer-Verlag.

    While drug abuse (DA) is strongly familial, we still have limited knowledge about the causes of its cross-generational transmission. We examined DA ascertained from national registers in offspring of three family types from the Swedish population [intact (n = 2,111,074), 'not-lived-with' (n = 165,315, where biological parents never lived with their offspring) and 'step' (n = 124,800 offspring)], which reflected, respectively, the effects of genes + rearing, genes only and rearing only. We replicated these results in three high-risk co-relative designs. Combined across mothers and fathers, the hazard ratio (HR) for DA in offspring given DA in parents was 3.52 in intact, 2.73 in 'not-lived-with' and 1.79 in stepfamilies. In 968 biological full or half-sibling pairs one of whom was reared by and the other never lived with their parent with DA, the HR for DA was greater in the reared than 'not-lived-with' child (HR 1.57). In 64 offspring pairs of a parent with DA, the HR for DA was greater in a reared biological v. step-parented non-biological child (HR 3.33). In 321 pairs of offspring of a parent with DA one of whom was a not-lived-with biological child and the second a step-parented non-biological child, the HR for DA was greater in the biological v. stepchild (HR 1.80). Both genetic and environmental factors contribute substantially to parent-offspring resemblance for DA. The general population contains informative family constellations that can complement more traditional adoption designs in clarifying the sources of parent-offspring resemblance.

  15. Continuity and Evolution: The Idea of “Co-creativity” in Chinese Art

    2014-06-01

    Full Text Available This paper seeks to explore an important characteristic of both traditional and contemporary Chinese art, that is, co-creativity. The author believes that co-creativity is a particular Chinese cultural sensibility that establishes the continuity of Chinese art and allows it to endure despite historical, societal and political changes throughout the centuries. This paper starts with an introduction of the idea of co-creativity in Chinese culture. One of its embodiments is the relationship between 'yin' and 'yang'. 'Yin 'and 'yang' both engender and fulfill each other, which is a co-relational and co-creative process. It then analyzes how the idea of co-creativity is demonstrated in traditional landscape painting through the expression of the oneness with nature and invitation to join a journey with the artist. Lastly, it demonstrates this continious co-creative cultural sensibility through analyzing two contemporary artists’ works. The author reads the submissive openness and vulnerability in Chinese female artist Chen Lingyang’s works as a continuity of the co-creative spirit of 'yin' and 'yang', nature and human. Chen’s work, rooted in her cultural sensibility, expresses a totally different statement of women’s desires and conditions than does that of American feminist artists Judy Chicago and Carolee Schneemann. Likewise, performance artist Ma Liuming’s 'Fen-Ma Liuming in… 'series seems inspired by nature’s image of co-creating the world. Different as these works may be in their formal aspects—from painting to poetry, from photography to performance— “co-creativity” is at the heart of Chinese cultural expression.

    Rice dwarf virus (RDV) is the causal agent of rice dwarf disease, which limits rice production in many areas of south East Asia. Transcriptional changes of rice in response to RDV infection have been characterized by Shimizu et al. and Satoh et al.. Both studies found induction of defense related genes and correlations between transcriptional changes and symptom development in RDV-infected rice. However, the same rice cultivar, namely Nipponbare belonging to the Japonic subspecies of rice was used in both studies. Gene expression changes of the indica subspecies of rice, namely Oryza sativa L. ssp. indica cv Yixiang2292 that show moderate resistance to RDV, in response to RDV infection were characterized using an Affymetrix Rice Genome Array. Differentially expressed genes (DEGs) were classified according to their Gene Ontology (GO) annotation. The effects of transient expression of Pns11 in Nicotiana benthaminana on the expression of nucleolar genes were studied using real-time PCR (RT-PCR). 856 genes involved in defense or other physiological processes were identified to be DEGs, most of which showed up-regulation. Ribosome- and nucleolus related genes were significantly enriched in the DEGs. Representative genes related to nucleolar function exhibited altered expression in N. benthaminana plants transiently expressing Pns11 of RDV. Induction of defense related genes is common for rice infected with RDV. There is a co-relation between symptom severity and transcriptional alteration in RDV infected rice. Besides ribosome, RDV may also target nucleolus to manipulate the translation machinery of rice. Given the tight links between nucleolus and ribosome, it is intriguing to speculate that RDV may enhance expression of ribosomal genes by targeting nucleolus through Pns11.

    Arsenicosis, due to contaminated drinking water, is a serious health hazard in terms of morbidity and mortality. Arsenic induced free radicals generated are known to cause cellular apoptosis through mitochondrial driven pathway. In the present study, we investigated the effect of arsenic interactions with various complexes of the electron transport chain and attempted to evaluate if there was any complex preference of arsenic that could trigger apoptosis. We also evaluated if chelation with monoisoamyl dimercaptosuccinic acid (MiADMSA) could reverse these detrimental effects. Our results indicate that arsenic exposure induced free radical generation in rat neuronal cells, which diminished mitochondrial potential and enzyme activities of all the complexes of the electron transport chain. Moreover, these complexes showed differential responses towards arsenic. These early events along with diminished ATP levels could be co-related with the later events of cytosolic migration of cytochrome c, altered bax/bcl{sub 2} ratio, and increased caspase 3 activity. Although MiADMSA could reverse most of these arsenic-induced altered variables to various extents, DNA damage remained unaffected. Our study for the first time demonstrates the differential effect of arsenic on the complexes leading to deficits in bioenergetics leading to apoptosis in rat brain. However, more in depth studies are warranted for better understanding of arsenic interactions with the mitochondria. -- Research highlights: Black-Right-Pointing-Pointer Arsenic impairs mitochondrial energy metabolism leading to neuronal apoptosis. Black-Right-Pointing-Pointer Arsenic differentially affects mitochondrial complexes, I - III and IV being more sensitive than complex II. Black-Right-Pointing-Pointer Arsenic-induced apoptosis initiates through ROS generation or impaired [Ca{sup 2+}]i homeostasis.

    Full Text Available Background: Previous studies regarding various types of malocclusions have found correlations between the angle of the base of the skull and prognathism. Aim of the study: This cephalometric study sought to investigate the function of the cranium base angle in different types of malocclusion on a group of Romanian subjects. Materials and methods: Forty-four cephalometric radiographs were selected from patients referred to orthodontic treatment. The cephalometric records were digitized, and with the CorelDRAW Graphics Suite X5 software 22 landmarks have been marked on each radiograph. A number of linear and angular variables were calculated. Results: The angle of the base of the skull was found to be higher in Class II Division 1 subjects compared to the Class I group. The cranial base lengths, N-S and S-Ba, were significantly larger in both categories of Class II malocclusion than in Class I patients, but measurements were comparable in Class I and Class III. The SNA angle showed no considerable variation between Class I subjects and the other groups. SNA-SNP was significantly increased above Class I values in Class II Division1 and Class II Division 2 groups. No significant dissimilarities were observed for these lengths between Class I and Class III patients. Conclusions: The angle of the cranium base (S-N-Ba, S-N-Ar does not have a major role in the progression of malocclusion. In Angle Class II malocclusion the SNA angle is increased, and SNB is increased in malocclusion Class III. The anterior skull base length is increased in Class II anomalies. The length of the maxillary bone base is increased in Class II malocclusions type; in Class III type of malocclusion the length of the mandible bone is increased.

    Health-Related Quality Of Life (HRQOL) among patients with End-Stage Renal Disease (ESRD) is significantly impacted by virtue of varied disease or treatment-related factors, and its evaluation along with existential concerns is required for providing comprehensive care to the patient. The aim of this study was to describe the various dimensions of HRQOL and existential concerns and to examine the relationship between the two among patients with ESRD. A cross-sectional descriptive study was conducted among 54 patients with ESRD undergoing maintenance hemodialysis in a teaching hospital. A semi-structured questionnaire was used to assess socio-demographic characteristics and existential concerns of the respondents. The HRQOL was evaluated using a standardized scale of Kidney Disease Quality of Life-Short Form (KDQOL-SF™) questionnaire. Data were presented as frequencies, mean ± Standard Deviation (SD) for baseline characteristics and scores. Pearson correlation was used to study the association between various domains of quality of life and existential concerns. Among HRQOL, the worst results obtained were in the domain of burden of kidney disease (33.45 ± 13.53), work status (49.07 ± 24.75), quality of social interaction (62.22 ±11.80), general health (43.06 ± 13.01), and physical functioning (47.50 ± 18.88). Disrupted personal integrity (12.80 ± 2.81) and loss of continuity (5.37 ± 1.17) were most bothersome existential concerns. A co-relational model behaves distinctly eliciting weak to strong association among various domains of HRQOL and existential concerns. Patients with ESRD reported impaired HRQOL in most of the domains. Existential concerns are distinguished as important dimensions of HRQOL. Association between HRQOL and existential concerns showed that these dimensions are distinct, and there is a need for assessing and attending these entities through a multidisciplinary approach to alleviate the suffering and achieving a sense of overall

    TrigDB is initially developed for the discrimination of teleseismic-origin false alarm in the case with unreasonably associated triggers producing mis-located epicenters. We have applied TrigDB to the current EEWS(Earthquake Early Warning System) from 2014. During the early stage of testing EEWS from 2011, we adapted ElarmS from US Berkeley BSL to Korean seismic network and applied more than 5 years. We found out that the real-time testing results of EEWS in Korea showed that all events inside of seismic network with bigger than magnitude 3.0 were well detected. However, two events located at sea area gave false location results with magnitude over 4.0 due to the long period and relatively high amplitude signals related to the teleseismic waves or regional deep sources. These teleseismic-relevant false events were caused by logical co-relation during association procedure and the corresponding geometric distribution of associated stations is crescent-shaped. Seismic stations are not deployed uniformly, so the expected bias ratio varies with evaluated epicentral location. This ratio is calculated in advance and stored into database, called as TrigDB, for the discrimination of teleseismic-origin false alarm. We upgraded this method, so called `TrigDB back filling', updating location with supplementary association of stations comparing triggered times between sandwiched stations which was not associated previously based on predefined criteria such as travel-time. And we have tested a module to reject outlier trigger times by setting a criteria comparing statistical values(Sigma) to the triggered times. The criteria of cutting off the outlier is slightly slow to work until the number of stations more than 8, however, the result of location is very much improved.

  3. Oxygen and hydrogen isotope studies of plutonic granitic rocks

    The primary deltaD values of the biotites and hornblendes in granitic batholiths are remarkably constant at about -50 to -85, identical to the values in regional metamorphic rocks, marine sediments and greenstones, and most weathering products in temperate climates. Therefore the primary water in these igneous rocks is probably not 'juvenile', but is ultimately derived by dehydration and/or partial melting of the lower crust or subducted lithosphere. Most granitic rocks have delta 18 O = +7.0 to +10.0, probably indicating significant involvment of high- 18 O metasedimentary or altered volcanic rocks in the melting process; such an origin is demanded for many other granodiorites and tonalites that have delta 18 O = +10 to +13. Gigantic meteoric-hydrothermal convective circulation systems were established in the epizonal portions of all batholiths, locally producing very low delta 18 O values (particularly in feldspars) during subsolidus exchange. Some granitic plutons in such environments also were emplaced as low- 18 O magmas probably formed by melting or assimilation of hydrothermally altered roof rocks. However, the water/rock ratios were typically low enough that over wide areas the only evidence for meteoric water exchange in the batholiths is given by low D/H ratios (deltaK as low as -180); for example, because of latitudinal isotopic variations in meteoric waters, as one moves north through the Cordilleran batholiths of western North America an increasingly higher proportion of the granitic rocks have deltaD values lower than -120. The lowering of deltaD values commonly corelates with re-setting of K-Ar ages. (Auth.)

    Screening for unruptured cerebral aneurysms (UCAs) using magnetic resonance imaging (MRI) and angiography (MRA) is prevalent in Japan. To reveal the prevalence of UCAs found during screening, we collected data of the results in 1999, in Tochigi prefecture. In the prefecture, of which the population was about 2 million, 26 institutions had been established in 1999, and 5,222 persons had been screened. These corresponded to 0.26% of all inhibitants of Tochigi prefecture. Of the 26 institutions, 24 cooperated in this study, and data was collected for 4,961 persons. We investigated the prevalence of UCAs, and compared it with that of subarachnoid hemorrhage (SAH) in Japan using the existing statistics. The UCAs were found in 143 (2.9%) of the 4,961 cases, 69 men and 74 women, with a mean age of 59.2 years. The prevalence of UCAs at screening and the prevalence of SAH in Japan co-relate in that this prevalence increases with age in both UCAs and SAH. However, after the age of 75, the prevalence of SAH decreases. People found with UCAs at screening were mainly in their 50's, but the member of those found with SAH increased gradually after that age. The rate of screening of women was lower than that of men, although both the prevalence of UCAs at screening and SAH of women is higher than that of men. We recommend that middle-aged persons, in their 40's and older, should request screening for UCAs. (author)

    Chemical Admixtures are added to concrete at the time of mixing of its constituents to impart workability. The requirement of right workability is the essence of good concrete. It has been found that the use of optimum use of admixtures is very important since low dosage may result in loss of fluidity and over dosage could lead to segregation, bleeding, excessive air entrainment etc in concrete. Hence it is essential to find optimum dosage of superplasticizer for getting good strength and workability. But large number of trial tests are required in the field to find the saturation dosage of superplasticizer in concrete which requires more materials and consume more time. The paper deals with developing a co-relation between the quantity requirements of superplasticiser in mortar to that of cement concrete to get good workability. In this work for preparing mortar and concrete 4 brands of locally available Portland pozzolana cement (PPC) and superplasticizer (SP) belonging to 4 different families namely Polycarboxylate Ether (PCE), Lignosulphate (LS), Sulfonated Naphthalene Formaldehyde (SNF) and Sulfonated Melamine Formaldehyde (SMF) are used. Two different brands of SP’s are taken from each family. Workability study on the superplasticized mortar with cement to sand ratio 1:1.5 and water cement ratio of 0.4 was performed using marsh cone and flow table test and workability study on the concrete with same cement/sand ratio and water cement ratio was done using slump cone and flow table test. Saturation dosage of superplasticizer in mortar and concrete determined experimentally was compared to study the correlation between two. Compressive strength study on concrete cubes were done on concrete mixes with a superplasticizer dosage corresponding to the saturation dosage and a comparative study were done to analyse the improvement in the compressive strength with addition of superplasticizer from different family.

    To describe findings of enhanced power Doppler sonography and DSA in experimentally induced VX2 carcinomas in rabbit thigh and to correlate the imaging findings with the histopathologic features. A total of 30 VX2 carcinomas were implanted in rabbit thigh, and after conventional and enhanced power Doppler sonography and DSA, histopathologic examination was performed. Enhanced power Doppler sonography and DSA, were used to determine the distribution pattern of tumor vascularity; to assess its grade and the percentage of a tumor area occupied by vessels, conventional and enhanced power Doppler sonography, as well as DSA, were used. The grade of necrosis and the development of fibrovascular stroma and capsule were histopathologically determined. The findings of power Doppler sonography were compared with those of DSA and the imaging features were correlated with the histopathologic features. At enhanced power Doppler sonography, the signal was either avascular (n=9), peripheral (n=15) or diffuse (n=6), while at DSA, the corresponding totals were eight, fourteen and eight. There was statistically significant corelation between enhanced power Doppler sonogrpahy and DSA, both in their depiction of the distribution of patterns of tumor vascularity and as regards their findings of grade and percentage of vascular area. As determined by both conventional and enhanced power Doppler sonogrpahy, and by DSA, grade of necrosis and the development of fibrovascular stroma and a capsule correlated with grade and the percentage of vascular area. Experimentally induced VX2 carcinomas in rabbit thigh demonstrated various patterns of tumor vascularity, and the findings of enhanced power Doppler sonography correlated with those of DSA. Tumor vascularity, as demonstrated by two imaging modalities, correlated closely with grade of necrosis and the development of fibrovascular stroma and a capsule, as revealed by histopathologic examination

    The IAEA transport regulations are scheduled to be introduced in Japan. New regulations are supposed to be set forth for low specific activity (LSA) material and industrial packaging (IP) as solidified concentrated waste water should correspond to the LSA material. Solidified concentrated waste water should be transported in accordance with the new transport regulations which reflect the IAEA transport regulations. As one of the regulations for LSA material, the leaching test for LSA-III materials states that the radioactive loss due to leaching without the packaging should not exceed 0.1 A 2 when left in the water for 7 days. This test method is called Transport regulations hereafter. Since the test had not been conducted in Japan before now, there was no available data. Consequently, it is necessary to make an assessment on whether the current solidified concentrated waste water can satisfy the leaching amount of radioactive nuclide specified in the IAEA transport regulations. If the test is performed in accordance with the IAEA transport regulations, however, it is necessary to measure the amount of radioactive nuclide actually leached from the solidified concentrated waste water. Since the solidified concentrated waste water is put in a drum cam, it is necessary to prepare large-scale hot test equipment. In this study, therefore, the leaching test was conducted on the solidified concentrated waste water to propose the means of a leaching assessment which can be conducted with ordinary equipment to evaluate the leaching for assessment of the adaptability to IAEA transport regulations. In addition, the leaching test was performed in accordance with the IAEA method to examine the co-relation between the transport regulations and the IAEA method. Many test results have been reported for the IAEA method in Japan, which will be detailed later on

    Full Text Available Morphometric characterization is an important element in the study of dynamic cellular behavior in plant responses to biotic and abiotic stimuli. The aim of study was to determine the morphometric parameters of meiocytes and pollen grains in different phases of microsporogenesis in fertile and induced androsterility sunflower plants. Thus, the comparative morphometric analysis revealed the gametocidal effect of gibberellin that is manifested as abnormal changes in shape and volume of cells. These modifications lead to deficiencies in the integrity/rigidity and, respectively, in the functionality of the cell wall, as well as in the physical properties of the protoplasm. The low values of morphometric parameters were also correlated with the degree of sterility of pollen grains. Rezumat. Caracterizarea morfometrică este un element important în studiul proceselor celulare dinamice ca răspuns la stimulii biotici şi abiotici. Scopul studiului constă în determinarea parametrilor morfometrici ai meiocitelor şi grăuncioarelor de polen în diferite faze ale microsporogenezei la plantele de floarea-soarelui fertile şi cu androsterilitate indusă. Astfel, analiza morfometrică comparativă a relevat efectul gametocid al giberelinei exprimat prin schimbările anormale ale formei şi volumului celulelor. Aceste modificări induc deficienţe atât în integritatea/rigiditatea şi, respectiv, în funcţionalitatea peretelui celular, cât şi în proprietăţile fizice ale protoplasmei. De asemenea, valorile scăzute ale parametrilor morfometrici au fost corelate cu gradul de sterilitate al grăuncioarelor de polen.

    Understanding and controlling natural and synthetic biointerfaces is known to be the key to a wide variety of application within cell culture and tissue engineering field. As both material characteristics and methods are important in tailoring biointerfaces characteristics, in this work we explore the feasibility of using Matrix Assisted Pulsed Laser Evaporation technique for obtaining synthetic copolymeric biocoatings (i.e. poly(ethylene glycol)-block-poly(ɛ-caprolactone) methyl ether) for evaluating in vitro Vero and MC3T3-E1 pre-osteoblasts cell response. Characterization and evaluation of the coated substrates were carried out using different techniques. The Fourier transform infrared spectroscopy data demonstrated that the main functional groups in the MAPLE-deposited films remained intact. Atomic Force Microscopy images showed the coatings to be continuous, with the surface roughness depending on the deposition parameters. Moreover, the behaviour of the coatings in medium mimicking the pH and temperature of the human body was studied and corelated to degradation. Spectro-ellipsometry (SE) and AFM measurements revealed the degradation trend during immersion time by the changes in coating thickness and roughness. In vitro biocompatibility was studied by indirect contact tests on Vero cells in accordance with ISO 10993-5/2009. The results obtained in terms of cell morphology (phase contrast microscopy) and cytotoxicity (LDH and MTT assays) proved biocompatibility. Furthermore, direct contact assays on MC3T3-E1 pre-osteoblasts demonstrated the capacity of all analyzed specimens to support cell adhesion, normal cellular morphology and growth.

    To investigate the expression of BAG3 gene in acue myeloid leukemia (AML) and its prognostic value. Real-time quantitative RT-PCR was used to detect the expression of BAG3 mRNA in 88 previously untreated AML patients. The corelation of BAG3 expression level with clinical characteristics and known prognostic markers of AML was analyzed. In 88 patients with AML, the expression of BAG3 mRNA in NPMI mutated AML patients was obviously lower than that in NPMI unmutated patients (P = 0.018). The expression level of BAG3 mRNA did not related to clinical parameters, such as age, sex, FAB subtype, WBC count, extra-modullary presentation, and to prognostic factors including cytogenetics, FLT3-ITD, c-kit and CEBPα mutation status (P > 0.05). The expression level of BAG3 had no obvious effect on complete remission (CR) of patients in first treatment. The expression level of BAG3 in non-M3 patients was higher than that in relapsed patients (P = 0.036). The expression level of BAG3 had no effect on overall survival (OS) of patients. The expression level of BAG3 does not correlated with known-prognostic markers of AML, only the expression level of BAG3 in NPM1 mutated patients is lower than that in NPM1 unmutated patients. The expression level of BAG3 has no effect on OS of AML patients, the BAG3 can not be difined as a prognostic marker in AML.

    Full Text Available Background: The family has a significant role both in the genesis and prognosis of obsessive-compulsive disorder (OCD. Early identification, treatment and prevention of relapse in patients with OCD have important therapeutic and psychosocial implications. Hence, to study and determine family factors like high expressed emotion (EE and family dysfunction are essential. These two factors play a significant role in the relapse and course of OCD. Aim: The aim was to study the relationship between family function, EE and OCD. Materials and Methods: The sample included 30 patients who were diagnosed with OCD using International Classification of Diseases-10 Diagnostic Criteria for Research criteria. Yale-Brown obsessive compulsive scale was used to assess the severity of OCD. EE was assessed in cases using Family Emotional Involvement and Criticism Scale and family function was assessed in cases using the family interaction pattern scale (FIPS. Statistical analysis was performed using Statistical Packages for Social Science. Patient and caregivers of the patients were assessed on self-developed socio-demographic proforma. Pearson co-relation co-efficient test was used to study the correlation between OCD, high EE and family dysfunction. Results: The result showed that there are significant correlations between high EE, family dysfunction and OCD. The Pearson correlation co-efficient between OCD and EE shows a significant correlation between the high EE of the caregiver and OCD with P < 0.01. The Pearson correlation co-efficient between OCD and Family Interaction Pattern Scale shows a significant correlation between the family dysfunction of the caregiver and OCD. Conclusion: Impaired family function and high EE in caregivers associated with OCD. Thus clinical interventions may improve the functional abilities of the caregivers.

    Full Text Available BACKGROUND Asphyxia can lead to severe hypoxic ischaemic organ damage in new-borns which may cause postnatal manifestation of hypoxicischaemic encephalopathy. Studies have found that the Apgar score failed to predict specific neurologic outcomes of the infants. Increased cord blood nucleated red blood cell in term neonates is an indicator of chronic intrauterine hypoxia. We set out to assess the role of nucleated RBC as a non-invasive, easy, cheap and at the same time early biochemical means of asphyxia diagnosis in our clinical setting. MATERIALS AND METHODS All inborn babies with Apgar scores <7 at 1 and 5 minutes of life were reviewed. Relevant information from mother case sheet were obtained. Cord blood samples was drawn and sent for blood gas analysis and number of NRBCs/100 white blood cells (WBC was determined using Leishman stain. RESULTS Our study proves the relevance of increase nucleated RBC in terms of early detection of birth asphyxia. Most common cause of birth asphyxia found was meconium aspiration. No co-relation was found with chorioamnionitis or maternal obstetrical history. CONCLUSION Many specific biomarkers are being investigated now a day for early detection of birth asphyxia. Umbilical cord pH is costly and may be underestimated in birth asphyxia. In our study, the elevated cord blood nRBC count was shown to be a good predictor of perinatal asphyxia. Since, it is cost-effective and does not require any special expertise or any high-tech facilities, it may be a useful, reliable, inexpensive and easily available marker to evaluate perinatal asphyxia. Hence, increase nucleated RBC has an important role in diagnosing and predicting the outcome of perinatal asphyxia.

    Full Text Available OBJECTIVE: The aim of this laboratory study is to evaluate the influence of the shape and the length limitation of superelastic nickel-titanium (NiTi archwires on lower incisors inclination during alignment and leveling. METHODS: Metal teeth mounted on a typodont articulator device were used to simulate a malocclusion of the mandibular arch (-3.5 mm model discrepancy. Three different shapes (Standard, Accuform and Ideal of superelastic NiTi archwires (Sentalloy, GAC, USA were tested. Specimens were divided in two groups: Group I, with no limitation of the archwire length; and Group II, with distal limitation. Each group had thirty specimens divided into three subgroups differentiated by the archwire shape. All groups used round wires with diameters of 0.014-in, 0.016-in, 0.018-in and 0.020-in. The recording of all intervals was accomplished using standardized digital photographs with orthogonal norm in relation to median sagittal plane. The buccolingual inclination of the incisor was registered using photographs and software CorelDraw. RESULTS: The results were obtained using ANOVA and Tukey's test at a significant level of 5%. The inclination of the lower incisor increased in both groups and subgroups. The shape of the archwire had statistically significant influence only in Group I - Standard (11.76º, Ideal (5.88º and Accuform (1.93º. Analyzing the influence of the length limitation, despite the mean incisor tipping in Group II (3.91º had been smaller than Group I (6.52º, no statistically significant difference was found, except for Standard, 3.89º with limitation and 11.76º without limitation. The greatest incisor tipping occurred with the 0.014-in archwires.

    Gossypium arboreumis resistant to Cotton leaf curl Burewala virus and its cognate Cotton leaf curl Multan beta satellite ( CLCuBuV and CLCuMB ). However, the G. arboreum wax deficient mutant (GaWM3) is susceptible to CLCuV . Therefore, epicuticular wax was characterized both quantitatively and qualitatively for its role as physical barrier against whitefly mediated viral transmission and co-related with the titer of each viral component (DNA-A, alphasatellite and betasatellite) in plants. The hypothesis was the CLCuV titer in cotton is dependent on the amount of wax laid down on plant surface and the wax composition. Analysis of the presence of viral genes, namely alphasatellite, betasatellite and DNA-A, via real-time PCR in cotton species indicated that these genes are detectable in G. hirsutum , G. harknessii and GaWM3, whereas no particle was detected in G. arboreum . Quantitative wax analysis revealed that G. arboreum contained 183 μg.cm -2 as compared to GaWM3 with only 95 μg.cm -2 . G. hirsutum and G. harknessii had 130 μg.cm -2 and 146 μg.cm -2 , respectively. The GCMS results depicted that Lanceol, cis was 45% in G. harknessii . Heptadecanoic acid was dominant in G. arboreum with 25.6%. GaWM3 had 18% 1,2,-Benenedicarboxylic acid. G. hirsutum contained 25% diisooctyl ester. The whitefly feeding assay with Nile Blue dye showed no color in whiteflies gut fed on G. arboreum . In contrast, color was observed in the rest of whiteflies. From results, it was concluded that reduced quantity as well as absence of (1) 3-trifluoroacetoxytetradecane, (2) 2-piperidinone,n-|4-bromo-n-butyl|, (3) 4-heptafluorobutyroxypentadecane, (4) Silane, trichlorodocosyl-, (5) 6- Octadecenoic acid, methyl ester, and (6) Heptadecanoicacid,16-methyl-,methyl ester in wax could make plants susceptible to CLCuV , infested by whiteflies.

    Full Text Available Context: The aqueous extracts of Urera baccifera Wedd. leaves and roots are used to inflammatory and infectious diseases in Brazilian folk medicine. Oxalic acid, a substance co-related with toxicity and stinging, was already quantified in this plant. Aims: To evaluate the action of leaves and roots infusions (1, 30, 75 g/L and the oxalic acid standard on mitosis as indicative of presumably antimitotic and genotoxic actions, using the Allium cepa test. Methods: Oxalic acid was quantified in the roots and leaves infusions by High-performance liquid chromatography (HPLC-DAD, with the mobile phase of 25 mM phosphate buffer (pH 2.5: acetonitrile at 95:5 (v/v. To the genotoxicity test, onion bulbs were used. After the rootlets germination, each bulb was submitted for 24 h of the individual treatments. Were analyzed 1000 cells per bulb, in a total of 5000 cells per treatment. Results: Results showed that all concentrations of roots infusions induced chromosomes abnormalities, except for the highest, that caused a substantial inhibition in the mitosis, precluding to be observed abnormalities. In the leaves infusions, only the two higher concentrations caused the highest values of damage in the cellular cycle. The oxalic acid also caused abnormalities in the mitosis, and may be considered responsible by part of the genotoxic action of U. baccifera. Conclusions: Oxalic acid can be responsible by part of the chromosomal abnormalities caused by U. baccifera, although, there must have more metabolites that evoke the same effect promoting the genotoxic effect of this nettle.

    Several techniques are available to measure red cell cholinesterase; therefore, evaluations with several methods provide a measure of concordance. An equation was formulated to transform native data of reference values to reference units of cholinesterase activity as measured by Michel and EQM tests. The experimental design was descriptive, transversal and prospective. The group sampled was a representative adult working population, aged 18-75, without previous exposure to cholinesterase inhibitors pesticides. The individuals were affiliated to the Social Security System and resided in Valle de Aburrá and Cercano Oriente Antioqueño (Antioquia Province, northwestern Colombia). Of 827 individuals, quantitative erythrocytes (Michel y EQM) tests exhibited "r" coefficients between 0.67 and R2 coefficient of 44%.,This indicated that one test explained the results in other test in 44% of the cases. The corelation was higher in Aburrá than in Oriente. The linear model for the 827 individuals was as follows: EQM U/g oxy-hemoglobin = 9.575 U/ g oxy-hemoglobin + 29.791 (Michel delta pH/hour). Michel delta pH/hr = 0.3312 delta pH/hour + 0.0149 (EQM U/g oxy-hemoglobin), where EQM was expressed in U/g oxy-hemoglobin and Michel pH change/hr. Inter-sections (coefficient a) and inclines (coefficient b) were significant in this model. In the adjusted equations, after exclusion of 12 extreme data (1.5% of 827), the r coefficient increased from 0.67 to 0.72 The adjusted equations were as follows: EQM U/g oxy-hemoglobin = 8.1884 U/g oxy-hemoglobin + 31.3920 (Michel delta pH/hour); Michel delta pH/hr = 0.2925 delta pH/hr + 0.0161 (EQM U/g oxy-hemoglobin). This system of linear equations permitted the transformation of Michel (delta PH/ hr) units to EQM (U/g oxy-hemoglobin) units and vice versa. This will facilitate data comparisons by clinicians and epidemiologists who are using these methods of cholinesterase measurement.

We evaluate the proposed algorithm on a mammographic image reference library with an Interactive Search-Assisted Decision Support (ISADS) system and on the medical image data set from ImageCLEF. Our results show that the boosting framework compares favorably to state-of-the-art approaches for distance metric learning in retrieval accuracy, with much lower computational cost. Additional evaluation with the COREL collection shows that our algorithm works well for regular image data sets.

    Since the foundation of stratigraphy geoscientists have recognized that data obtained from stratigraphic columns (SC), two dimensional schemes recording descriptions of both geological and paleontological features (e.g., thickness of rock packages, grain size, fossil and lithological components, and sedimentary structures), are key elements for establishing reliable hypotheses about the distribution in space and time of rock sequences, and ancient sedimentary environmental and paleobiological dynamics. Despite the tremendous advances on the way geoscientists store, plot, and quantitatively analyze sedimentological and paleontological data (e.g., Macrostrat [http://www.macrostrat.org/], Paleobiology Database [http://www.paleodb.org/], respectively), there is still a lack of computational methodologies designed to quantitatively examine data from a highly detailed SCs. Moreover, frequently the stratigraphic information is plotted "manually" using vector graphics editors (e.g., Corel Draw, Illustrator), however, this information although store on a digital format, cannot be used readily for any quantitative analysis. Therefore, any attempt to examine the stratigraphic data in an analytical fashion necessarily takes further steps. Given these issues, we have developed the sofware 'Stratigraphic Data Analysis in R' (SDAR), which stores in a database all sedimentological, stratigraphic, and paleontological information collected from a SC, allowing users to generate high-quality graphic plots (including one or multiple features stored in the database). SDAR also encompasses quantitative analyses helping users to quantify stratigraphic information (e.g. grain size, sorting and rounding, proportion of sand/shale). Finally, given that the SDAR analysis module, has been written in the open-source high-level computer language "R graphics/statistics language" [R Development Core Team, 2014], it is already loaded with many of the crucial features required to accomplish basic and

    201-TlCl myocardial imaging studies were performed to evaluate systolic pressure of right ventricle on 107 patients including 89 patients with congenital cardiac disease, patients with primary pulmonary hypertension and 13 patients with history of MCLS with the age range of 2 months to 17 years. The congenital cardiac disease group included 30 patients with tetralogy of Fallot, 8 patients with pulmonary stenosis (included 1 patient with double chambered right ventricle), 20 patients with ventricular septal defect, 10 patients with patent ductus arteriosus, 9 patients with atrial septal defect and 12 patients with complete transposition of greate arteries. None of the patients with history of MCLS had coronary involvement. 50 μCi/kg of 201-TlCl was infused intravenously and after 15 minutes the images were obtained from 5 directions (anterior, LAO 30, LAO 45, LAO 60 and lateral). The angle was determined to demonstrate the intraventricular septum and ventricular free walls cleary separated. The image of end-diastolic phase was obtained with ECG syncronized gated method from that direction. The ROI (region of interest) was defined as a slice line by drawing two lines perpendicular to the septum and the counts of the left and right ventricular free wall (Cl and Cr) were analized to evaluate the pressure of right ventricle. The pressure of ventricles were obtained by cardiac catheterization performed at the same time with myocardial imaging. The ratio of Cl and Cr (Cr/Cl) had good correlation with the ratio of peak systolic pressure of left ventricle and right ventricle (regression equation Y=0.84X+0.08, r=0.87). In each congenital heart disease group, very good corelation was also demonstrated (Y=1.46X-0.30, r=0.96 in PS ; Y=0.70X0.20, r=0.91 in VSD ; Y=0.86X+0.15, r=0.78 in ASD and Y=0.72X+0.24, r=0.80 in PDA). Thus 201-TlCl myocardial imaging was useful method to evaluate right ventricular pressure noninvasively in congenital cardiac disease. (author)

    The B-site ordered double perovskite oxides LaPbMSbO{sub 6} (M=Co, Ni) have been synthesized via the modified Sol–Gel precursor two-step route. Rietveld refinements reveal strong abnormal structural distortion and BO{sub 6} octahedral deformation appearing along the ab plane. Owing to the cooperative Jahn–Teller effect of Co{sup 2+} and Pb{sup 2+} ions, the Co-related compound exhibits almost complete Co{sup 2+}–Sb{sup 5+} order. For magnetic properties, spin-canted antiferromagnetic state with high extent of magnetic frustration is confirmed. The Ni-related compound presents heavier magnetic frustration for introducing tiny disorder on site occupation accompanied with valence state and further enhancing the complexity of magnetic competition. Dielectric measurements present a considerable temperature dependent dielectric relaxation with great dc-like loss feature in the LaPbCoSbO{sub 6}. For LaPbNiSbO{sub 6}, however, the permittivity with low dielectric loss is shown to be insensitive to either temperature or frequency. The corresponding electronic active energy manifests that the weakly bounded 3d-electron is prone to hop in a more distorted Co–Sb sublattice. - Graphical abstract: XRD Rietveld refinement result of LaPbCoSbO{sub 6} presented a large BO{sub 6} octahedral distortion along the ab plane. Based upon the variations from Co–O–Sb bond angles, a fierce competition from many extended magnetic coupling routes (M–O–O–M) would induce a considerably large magnetic frustration and electron hopping restriction. - Highlights: • Highly ordered LaPbMSbO{sub 6} (M=Co, Ni) were synthesized. • Abnormal structural distortion appeared in the ab plane. • Strong magnetic frustration was confirmed via M{sup 2+}–O–O–M{sup 2+} route. • Dielectric measurements presented a large difference between Co and Ni samples. • 3d-electronic structure determines lattice distortion and physical properties.

    Full Text Available Aim: To determine the shaping ability and cleaning efficiency of hand K-flexofiles, ProTaper, LightSpeed and Mtwo instruments during the preparation of curved root canals in extracted human teeth. Materials and Methods: A total of 120 root canals of mandibular and maxillary molars with curvature more than 20° were divided into four groups of 30 each. In group A, canals were prepared using hand K-flexofiles following the crown down technique. In group B LightSpeed, in group C ProTaper, and in group D Mtwo rotary instruments were used to prepare the root canals. Using pre- and post-instrumentation radiographs, straightening of the canal curvature was determined with Corel Draw 9.0 software tools. The amount of debris and smear layer were quantified at three different areas (coronal, middle, and apical thirds of root canal using SEM. The collected data were analyzed statistically using Student′s paired ′t′ test. Results: The mean change in curvature for hand K-files was 7.71°, for ProTaper files 6.03°, for Mtwo 5.43°, and for LightSpeed instruments were found to be 4.57°. The percentage change in the curvature for all the four groups was statistically highly significant (P< 0.01. LightSpeed instruments maintained the original canal curvature significantly (P< 0.01 better than the other instruments. For leftover debris, the minimum percentage was found to be associated with ProTaper (65.48% followed by Mtwo (66.22%, LightSpeed (71.67% and the maximum with hand K-files (74.16%. However, the difference in mean leftover debris between ProTaper and Mtwo was not significant. Conclusion: ProTaper and Mtwo resulted in good cleaning, and LightSpeed maintained the original canal curvature better than the ProTaper, Mtwo, or Hand K-files.

    To study the prevalence of metabolic syndrome (MBS) in Indian women and to see how does it correlate to body mass index (BMI) and polycystic ovarian syndrome (PCOS) in this population. Prospective cross-sectional observational study. Infertility clinic of a tertiary center. Two hundred women, 120 with PCOs and 80 age-matched controls were enrolled. The prevalence of MBS was studied in the women with and without and was co related to BMI by further subgrouping as team (BMI 23 kg/m2). The sample size was: team controls-40, obese controls-40, team PCOS-80. Each subject underwent a physical examination and laboratory evaluation for the diagnosis of MBS, which was defined according to the guidelines of National Cholesterol Education Program Adult Treatment Pamel (NCEP ATP III) 2005. None. Subjects with and without PCOs were compared with each other for the prevalence of MBS, and similarly team subjects were compared with obese subjects. Receiver operator characteristic (ROC) curves were obtained for both the PCOS and non PCOS population separately, co-relating the prevalence of MBS with BMI. These ROC curves were used to establish the cut off values of BMI, which could best predict the risk of MBS. The prevalence of MBS was significantly higher in the women with PCOS, as compared to age-matched controls. Similarly, when BMI was considered, MBS was more prevalent in overweight subjects than in lean subjects with or without PCOS. In subgroup analysis, the presence of PCOS had a lesser impact on the prevalence of MBS as compared to non-PCOS controls with higher BMI. The relative risk of MBS increased as follows: lean controls-1, lean PCOS-2.66, obese controls-5.33, and obese PCOS-6.5. The most appropriate cut-off level of BMI for predicting the risk of MBS in Indian women without PCOS seems to be 23 kg/m(2), whereas, with PCOS, it was 22.5 kg/m(2). MBS is more prevalent in women with PCOS. However, obesity is an independent and stronger risk factor for developing MBS. To

    Beclin 1, an important autophagy-related protein in human cells, is involved in cell death and cell survival. Beclin 1 mapped to human chromosome 17q21. It is widely expressed in normal mammary epithelial cells. Although down-regulated expression with mono-allelic deletions of beclin 1 gene was frequently observed in breast tumors, whether there was other regulatory mechanism of beclin 1 was to be investigated. We studied the expression of beclin 1 and explored the possible regulatory mechanisms on its expression in breast tumors. 20 pairs of tumors and adjacent normal tissues from patients with sporadic breast invasive ductal cancer (IDCs) were collected. The mRNA expression of beclin 1 was detected by real-time quantitative RT-PCR. Loss of heterozygosity (LOH) was determined by real-time quantitative PCR and microsatellite methods. The protein expression of beclin 1, p53, BRCA1 and BRCA2 was assessed by immunohistochemistry. CpG islands in 5' genomic region of beclin 1 gene were identified using MethylPrimer Program. Sodium bisulfite sequencing was used in examining the methylation status of each CpG island. Decreased beclin 1 mRNA expression was detected in 70% of the breast tumors, and the protein levels were co-related to the mRNA levels. Expression of beclin 1 mRNA was demonstrated to be much higher in the BRCA1 positive tumors than that in the BRCA1 negative ones. Loss of heterozygosity was detected in more than 45% of the breast tumors, and a dense cluster of CpG islands was found from the 5' end to the intron 2 of the beclin 1 gene. Methylation analysis showed that the promoter and the intron 2 of beclin 1 were aberrantly methylated in the tumors with decreased expression. These data indicated that LOH and aberrant DNA methylation might be the possible reasons of the decreased expression of beclin 1 in the breast tumors. The findings here shed some new light on the regulatory mechanisms of beclin 1 in breast cancer

    Mice have been widely used in experimental protocols involving ionizing radiation. Biological effects (Be) induced by radiation can compromise studies results. Good estimates of mouse whole body and organs absorbed dose could provide valuable information to researchers. The aim of this study was to create and test a new voxel phantom for mice dosimetry from -Digimouse- project images. Micro CT images from Digimouse project were used in this work. Corel PHOTOPAINT software was utilized in segmentation process. The three-dimensional (3-D) model assembly and its voxel size manipulation were performed by Image J. SISCODES was used to adapt the model to run in MCNPX Monte Carlo code. The resulting model was called DM{sub B}RA. The volume and mass of segmented organs were compared with data available in literature. For the preliminary tests the heart was considered the source organ. Photons of diverse energies were simulated and Saf values obtained through F6:p and + F6 MCNPX tallies. The results were compared with reference data. 3-D picturing of absorbed doses patterns and relative errors distribution were generated by a C++ -in house- made program and visualized through Amide software. The organ masses of DM{sub B}RA correlated well with two models that were based on same set of images. However some organs, like eyes and adrenals, skeleton and brain showed large discrepancies. Segmentation of an identical image set by different persons and/or methods can result significant organ masses variations. We believe that the main causes of these differences were: i) operator dependent subjectivity in the definition of organ limits during the segmentation processes; and i i) distinct voxel dimensions between evaluated models. Lack of reference data for mice models construction and dosimetry was detected. Comparison with other models originated from different mice strains also demonstrated that the anatomical and size variability can be significant. Use of + F6 tally for mouse

    Multiple biological effects of tributyltin (TBT) on juvenile salmon have been investigated. Fish were exposed for 7 days to waterborne TBT at nominal concentrations of 50 and 250 microg/L dissolved in dimethyl sulfoxide (DMSO). Hepatic samples were analyzed for gene expression patterns in the hormonal and xenobiotic biotransformation pathways using validated real-time PCR method. Immunochemical and several cytochrome P450 (CYP)-mediated enzyme activity (ethoxyresorufin: EROD, benzyloxyresorufin: BROD, methoxyresorufin: MROD and pentoxyresorufin: PROD) assays were analyzed. Our data show that TBT produced concentration-specific decrease of estrogen receptor-alpha (ERalpha), vitellogenin (Vtg), zona radiata protein (Zr-protein) and increase of estrogen receptor-beta (ERbeta) and androgen receptor-beta (ARbeta) in the hormonal pathway. In the xenobiotic biotransformation pathway, TBT produced apparent increase and decrease at respective low and high concentration, on aryl hydrocarbon receptor-alpha (AhRalpha), AhR nuclear translocator (ARNT) and AhR repressor (AhRR) mRNA. The expression of CYP1A1 and GST showed a TBT concentration-dependent decrease. The AhRbeta, CYP3A and uridine diphosphoglucuronosyl transferase (UGT) mRNA expressions were significantly induced after exposure to TBT. Immunochemical analysis of CYP3A and CYP1A1 protein levels confirmed the TBT effects observed at the transcriptional levels. The effect of TBT on the biotransformation enzyme gene expressions partially co-related but did not directly parallel enzyme activity levels for EROD, BROD, MROD and PROD. In general, these findings confirm previous reports on the endocrine effects of TBT, in addition to effects on hepatic CYP1A isoenzyme at the transcriptional level that transcends to protein and enzymatic levels. The induced expression patterns of CYP3A and UGT mRNA after TBT exposure, suggest the involvement of CYP3A and UGT in TBT metabolism in fish. The effect of TBT on CYP3A is proposed to

    Full Text Available Sour cherry is an important fruit in Croatian orchards. Cultivar Oblačinska is predominant in existing orchards with noted intracultivar phenotypic heterogeneity. In this study, the genetic variability of 22 genotypes of cvs. Oblačinska, Maraska and Cigančica, as well as standard cvs. Kelleris 14, Kelleris 16, Kereška, Rexelle and Heimann conserved were investigated. Two types of molecular markers were used: microsatellite markers (SSR in order to identify intercultivar, and AFLP in order to identify intracultivar variabilities. A set of 12 SSR markers revealed small genetic distance between cvs. Maraska and Oblačinska while cv. Cigančica is affined to cv. Oblačinska. Furthermore, cvs. Oblačinska, Cigančica and Maraska were characterized compared to standard ones. AFLP markers didn`t confirm significant intracultivar variability of cv. Oblačinska although the variability has been approved at the morphological, chemical and pomological level. Significant corelation between SSR and AFLP markers was found. Identification of sour cherry cultivars tolerant to drought will enable the sustainability of fruit production with respect to the climate change in the future. For this purpose, the tolerance of seven sour cherry genotypes (cvs. Kelleris 16, Maraska, Cigančica and Oblačinska represented by 4 genotypes: OS, 18, D6 and BOR to drought conditions was tested in order to isolate genotypes with the desired properties. In the greenhouse experiment, cherry plants were exposed to drought stress. The leaf relative water content, OJIP test parameters which specify efficiency of the photosynthetic system based on measurements of chlorophyll a fluorescence, and concentrations of photo-synthetic pigments during the experiment were measured as markers of drought tolerance. Photosynthetic performance index (PIABS comprises three key events in the reaction centre of photosystem II affecting the photosynthetic activity: the absorption of energy

    Full Text Available CORELATION BETWEEN ISLAM AND ECONOMY. This paper aims to identifies about the correlation between economic and Islam. Islam is the perfect religion that governs all things in life, including the economy. This is evident with the concept of  well-being which is described in the al-Quran and Sunnah. Basically the goal of every human life is to prosper, although humans make sense of  well- being with a different perspective. Most understand economics assume that welfare is the welfare of  earthly material. But to make sense of well-being with the term al-Falah, is meaning holistic wellbeing and balance between material and spiritual dimensions. al-Quran and Sunnah have taught that the human being will be achieved if  living in balance between material and spiritual. This is because human life does not just stop in the life of this world, but there is still a second life that will be faced by humanity in the hereafter, and well-being will be achieved with the truth is that people can balance the needs of the world and the hereafter, and that is what is taught in Islamic economics. Keywords: Islam, Economy, Prosperity. Tulisan ini bertujuan untuk menjelasakn tentang korelasi antara ekonomi  dan  Islam.  Islam  adalah  agama  yang  sempurna  yang mengatur segala hal dalam kehidupan ini, termasuk juga ekonomi. Hal ini terbukti dengan konsep kesejahteraan yang dipaparkan dalam al-Quran dan Sunnah. Pada dasarnya tujuan hidup setiap manusia adalah untuk mencapai kesejahteraan, meskipun manusia memaknai kesejahteraan dengan perspektif  yang berbeda-beda. Sebagian besar paham ekonomi menganggap bahwa kesejahteraan adalah kesejahteraan material duniawi. Namun Islam memaknai kesejahteraan dengan istilah  Falah  yang  berarti  kesejahteraan  holistik  dan  seimbang antara dimensi material dan spiritual.

    Purpose: Simultaneous brain PET/MRI faces an important issue of validation of accurate MRI based attenuation correction (AC) method for precise quantitation of brain PET data unlike in PET/CT systems where the use of standard, validated CT based AC is routinely available. The aim of this study was to investigate the feasibility of evaluation of semiquantitative 18 F-FDG PET parameters derived from simultaneous brain PET/MRI using ultrashort echo time (UTE) sequences for AC and to assess their agreement with those obtained from PET/CT examination. Methods: Sixteen patients (age range 18–73 years; mean age 49.43 (19.3) years; 13 men 3 women) underwent simultaneous brain PET/MRI followed immediately by PET/CT. Quantitative analysis of brain PET images obtained from both studies was undertaken using Scenium v.1 brain analysis software package. Twenty ROIs for various brain regions were system generated and 6 semiquantitative parameters including maximum standardized uptake value (SUV max), SUV mean, minimum SUV (SUV min), minimum standard deviation (SD min), maximum SD (SD max) and SD from mean were calculated for both sets of PET data for each patient. Intra-class correlation coefficients (ICCs) were determined to assess agreement between the various semiquantitative parameters for the two PET data sets. Results: Intra-class co-relation between the two PET data sets for SUV max, SUV mean and SD max was highly significant (p < 0.00) for all the 20 predefined brain regions with ICC > 0.9. SD from mean was also found to be statistically significant for all the predefined brain regions with ICC > 0.8. However, SUV max and SUV mean values obtained from PET/MRI were significantly lower compared to those of PET/CT for all the predefined brain regions. Conclusion: PET quantitation accuracy using the MRI based UTE sequences for AC in simultaneous brain PET/MRI is reliable in a clinical setting, being similar to that obtained using PET/CT

    2009-11-01

    Within this thesis are discussed two main topics of contemporary astrophysics. The first is that of machine learning algorithms for astronomy whilst the second is that of magnetic cataclysmic variables (mCVs). To begin, an overview is given of ISINA: INTEGRAL Scouce Identifiction Network Algorithm. This machine learning algorithm, using random forests, is applied to the IBIS/ISGRI data set in order to ease the production of unbiased future soft gamma-ray source catalogues. The feature extraction process on an initial candidate list is described together with feature merging. Three trainng and testing sets are created in order to deal with the diverse time-scales encountered when dealing with the gamma-ray sky: one dealing with faint persistent source recognition, one dealing with strong persistent sources and a final one dealing with transients. For the latter, a new transient detection technique is introduced and described: the transient matrix. Finally the performance of the network is assessed and discussed using the testing set and some illustrative source examples. ISINA is also compared to the more conventional approach of visual inspection. Next mCVs are discussed, and in particular the properties arising from a hard X-ray selected sample which has proven remarkably efficient in detecting intermediate polars and asynchronous polars, two of the rarest type of cataclysmic variables (CVs). This thesis focuses particularly on the link between hard X-ray properties and spin/orbital periods. To this end, a new sample of these objects is constructed by cross-corelating candidate sources detected in INTEGRAL/IBIS observations against catalogues of known CVs. Also included in the analysis are hard X-ray Observations from Swift/BAT and SUZAKU/HXD in order to make the study more complete. It is found that most hard X-ray detected mCVs have Pspin/Porb<0.1 above the period gap. In this respect, attention is given to the very low number of detected systems in any ban

    Objective: To determine the response of treatment with standard interferon and Ribazole in treatment naive hepatitis C infected patients, with different grades of activity. Design: A quasi-experimental study. Place and Duration of Study: This study was carried out at the Department of Medicine, KRL General Hospital, Islamabad, from January 2001 to September 2004. Patients and Methods: A total of 300 patients were enrolled. All patients were anti-HCV positive confirmed by device method, PCR positive and had 3a genotype. A specially-designed proforma containing the patient profile, family transmission, and baseline laboratory values was filled. All patients were treated according to a set protocol of Interferon plus ribavirin therapy (IFN alpha 2a, 3MU t.i.w 24 weeks plus ribavirin 1000 to 1200 mg/day) for six months. Chi-square tests were used to analyze the data. Primary end point was a sustained virological response (SVR) that is response assessed after six months of completion of treatment. Results: Over a period of four years response rates to standard Interferon plus Ribazole therapy were studied. Out of the total 300 patients data was available for 161 patients as 60 patients were excluded and 79 patients are currently under treatment. Treatment was stopped in 3 patients due to serious side effects. In the 161 patients, 135 (83.8%), achieved response at the end of treatment at six months; End of Treatment Complete Response (EOTCR); and 26 (16.14%) were non-responders (NR). Out of the complete responders, 68 patients had been followed completely up to six months after the treatment to asses Sustained Viral Response (SVR) defined as undetectable HCV RNA in serum at the end of six months post treatment follow-up. Sustained viral response was seen in 46 patients Le. 68% ( CI: 57-79%) and 22(32.3%) were relapsers (those who developed recurrence of viremia after having achieved eradication at the end of six months treatment). Response rates are co-related with

    Full Text Available Objective: To study the prevalence of metabolic syndrome (MBS in Indian women and to see how does it correlate to body mass index (BMI and polycystic ovarian syndrome (PCOS in this population. Study Design: Prospective cross-sectional observational study. Setting: Infertility clinic of a tertiary center.  Materials and Methods: Two hundred women, 120 with PCOs and 80 age-matched controls were enrolled. The prevalence of MBS was studied in the women with and without and was co related to BMI by further subgrouping as team (BMI 23 kg/m2. The sample size was: team controls-40, obese controls-40, team PCOS-80. Each subject underwent a physical examination and laboratory evaluation for the diagnosis of MBS, which was defined according to the guidelines of National Cholesterol Education Program Adult Treatment Pamel (NCEP ATP III 2005. INTERVENTION: None. Main Outcome Measures: Main Outcome Measures: Subjects with and without PCOs were compared with each other for the prevalence of MBS, and similarly team subjects were compared with obese subjects. Receiver operator characteristic (ROC curves were obtained for both the PCOS and non PCOS population separately, co-relating the prevalence of MBS with BMI. These ROC curves were used to establish the cut off values of BMI, which could best predict the risk of MBS. Results: The prevalence of MBS was significantly higher in the women with PCOS, as compared to age-matched controls. Similarly, when BMI was considered, MBS was more prevalent in overweight subjects than in lean subjects with or without PCOS. In subgroup analysis, the presence of PCOS had a lesser impact on the prevalence of MBS as compared to non-PCOS controls with higher BMI. The relative risk of MBS increased as follows: lean controls-1, lean PCOS-2.66, obese controls-5.33, and obese PCOS-6.5. The most appropriate cut-off level of BMI for predicting the risk of MBS in Indian women without PCOS seems to be 23 kg/m 2 , whereas, with PCOS, it

    Full Text Available White blood cell (WBC count is a common clinical measure from complete blood count assays, and it varies widely among healthy individuals. Total WBC count and its constituent subtypes have been shown to be moderately heritable, with the heritability estimates varying across cell types. We studied 19,509 subjects from seven cohorts in a discovery analysis, and 11,823 subjects from ten cohorts for replication analyses, to determine genetic factors influencing variability within the normal hematological range for total WBC count and five WBC subtype measures. Cohort specific data was supplied by the CHARGE, HeamGen, and INGI consortia, as well as independent collaborative studies. We identified and replicated ten associations with total WBC count and five WBC subtypes at seven different genomic loci (total WBC count-6p21 in the HLA region, 17q21 near ORMDL3, and CSF3; neutrophil count-17q21; basophil count- 3p21 near RPN1 and C3orf27; lymphocyte count-6p21, 19p13 at EPS15L1; monocyte count-2q31 at ITGA4, 3q21, 8q24 an intergenic region, 9q31 near EDG2, including three previously reported associations and seven novel associations. To investigate functional relationships among variants contributing to variability in the six WBC traits, we utilized gene expression- and pathways-based analyses. We implemented gene-clustering algorithms to evaluate functional connectivity among implicated loci and showed functional relationships across cell types. Gene expression data from whole blood was utilized to show that significant biological consequences can be extracted from our genome-wide analyses, with effect estimates for significant loci from the meta-analyses being highly corellated with the proximal gene expression. In addition, collaborative efforts between the groups contributing to this study and related studies conducted by the COGENT and RIKEN groups allowed for the examination of effect homogeneity for genome-wide significant associations across

    As an international exchange student from the Geological Sciences Department at San Diego State University (SDSU), I joined the KKN-PPM program at Universitas Gadjah Mada (UGM), Yogyakarta, Indonesia, in July 2011 for 12 days (July 4th to July 16th) of its two month duration (July 4th to August 25th). The KKN-PPM group I was attached was designated 154 and was focused in Plosorejo Village, Karanganyar, Kerjo, Central Java, Indonesia. The mission of KKN-PPM 154 was to survey Plosorejo village for existing landslides, to generate a simple hazard susceptibility map that can be understood by local villagers, and then to begin dissemination of that map into the community. To generate our susceptibility map we first conducted a geological survey of the existing landslides in the field study area, with a focus on determining landslide triggers and gauging areas for susceptibility for future landslides. The methods for gauging susceptibility included lithological observation, the presence of linear cracking, visible loss of structural integrity in structures such as villager homes, as well as collaboration with local residents and with the local rescue and response team. There were three color distinctions used in representing susceptibility which were green, where there is no immediate danger of landslide damage; orange, where transportation routes are at risk of being disrupted by landslides; and red, where imminent landslide potential puts a home in direct danger. The landslide inventory and susceptibility data was compiled into digital mediums such as CorelDraw, ArcGIS and Google Earth. Once a technical map was generated, we presented it to the village leadership for confirmation and modification based on their experience. Finally, we began to use the technical susceptibility map to draft evacuation routes and meeting points in the event of landslides, as well as simple susceptibility maps that can be understood and utilized by local villagers.

    Relationship between Body Mass Index and Saliva Flow Rate (A Study in Faculty of Dentistry, Andalas University. Saliva flow rate is an affecting factor of caries formation. Adequate saliva flow rate can prevent cariess formation process and progression of periodontal disease and oral infection. Nutritional status is known as an influencing factor of saliva flow rate. The parameter of nutritional status is Body Mass Index (BMI. The purpose of this study is to discover the relation between BMI and saliva flow rate in College Students of the Dentistry Faculty Andalas University. This observational study with cross sectional design was conducted to 24 college students of the Dentistry Faculty Andalas University whose ages were 18-25 years old who complied with inclussion and exclussion criteria. BMI was calculated with BMI formula. The saliva flow rate was determined with Sialometry Method of Navazesh 2008 with ”ml/minute” unit. The univariat data analysis was caried out to describe each variable. Normality test Kolmogorov Smirnoff was done to see the normal distribution (p > 0,05. After the distribution was proven to be normal, corelation and regression test was executed to discover the relation between BMI and saliva flow rate. Based on the correlation test result, BMI of college students of the Dentistry Faculty Andalas University is χχ ± SD = 24,6 ± 6,02 kg/m2 and saliva flow rate is χχ ± SD = 0,29 ± 0,1 ml/minute. The relation between BMI and saliva flow rate expresses medium correlation with negative direction ( r = - 0,451. The result of linear regression shows that Saliva Flow Rate = 0,404 - 0,008*(BMI. The coefficient of regression BMI 0.008 shows that increasing 1 unit of BMI will decrease saliva flow rate 0,008 ml/minute. This study concludes that there is correlation between Body Mass Index and saliva flow rate. Obesity group has the lowest saliva flow rate, while the saliva flow rate does not decrease in underweight group.

    Mice have been widely used in experimental protocols involving ionizing radiation. Biological effects (Be) induced by radiation can compromise studies results. Good estimates of mouse whole body and organs absorbed dose could provide valuable information to researchers. The aim of this study was to create and test a new voxel phantom for mice dosimetry from -Digimouse- project images. Micro CT images from Digimouse project were used in this work. Corel PHOTOPAINT software was utilized in segmentation process. The three-dimensional (3-D) model assembly and its voxel size manipulation were performed by Image J. SISCODES was used to adapt the model to run in MCNPX Monte Carlo code. The resulting model was called DM B RA. The volume and mass of segmented organs were compared with data available in literature. For the preliminary tests the heart was considered the source organ. Photons of diverse energies were simulated and Saf values obtained through F6:p and + F6 MCNPX tallies. The results were compared with reference data. 3-D picturing of absorbed doses patterns and relative errors distribution were generated by a C++ -in house- made program and visualized through Amide software. The organ masses of DM B RA correlated well with two models that were based on same set of images. However some organs, like eyes and adrenals, skeleton and brain showed large discrepancies. Segmentation of an identical image set by different persons and/or methods can result significant organ masses variations. We believe that the main causes of these differences were: i) operator dependent subjectivity in the definition of organ limits during the segmentation processes; and i i) distinct voxel dimensions between evaluated models. Lack of reference data for mice models construction and dosimetry was detected. Comparison with other models originated from different mice strains also demonstrated that the anatomical and size variability can be significant. Use of + F6 tally for mouse phantoms

    In order to explore the effect of Mirabilis jalapa Linn. growth on the structure characteristics of the microbial community and the degradation of petroleum hydrocarbon (TPH) in the petroleum-contaminated saline-alkali soil, Microbial biomass and species in the rhizosphere soils of Mirabilis jalapa Linn. in the contaminated saline soil were studied with the technology of phospholipid fatty acids (PLFAs) analysis. The results showed that comparing to CK soils without Mirabilis jalapa Linn., the ratio of PLFAs species varied were 71. 4%, 69. 2% and 33. 3% in the spring, summer and autumn season, respectively. In addition, there was distinct difference of the biomasses of the microbial community between the CK and rhizosphere soils and among the difference seasons of growth of Mirabilis jalapa Linn.. Compare to CK soil, the degradation rates of total petroleum hydrocarbon (TPH) was increased by 47. 6%, 28. 3%, and 18. 9% in spring, summer, and autumn rhizosphere soils, respectively. Correlation analysis was used to determine the correlation between TPH degradation and the soil microbial community. 77. 8% of the total soil microbial PLFAs species showed positive correlation to the TPH degradation (the correlation coefficient r > 0), among which, 55. 6% of PLFAs species showed high positive correlation(the correlation coefficient was r≥0. 8). In addition, the relative content of SAT and MONO had high correlation with TPH degradation in the CK sample soils, the corelation coefficient were 0. 92 and 0. 60 respectively; However, the percent of positive correlation was 42. 1% in the rhizosphere soils with 21. 1% of them had high positive correlation. The relative content of TBSAT, MONO and CYCLO had moderate or low correlation in rhizosphere soils, and the correlation coefficient were 0. 56, 0. 50, and 0. 07 respectively.

    Archaeological research is fundamental in the process of obtaining a greater understanding on the intricate dynamics between the human species and the 'natural' environment. Deep historical processes can evaluate the complex interactions that eventually led to the human species as the dominating agent, in terms of the Earth's biotic and abiotic processes. Regional landscape studies can determine whether the human species can be evaluated as a formative element in soil formation processes during the Holocene. This study is directed to examine early anthropogenic land cover change (ALCC) in the Meuse-Demer-Scheldt region, in the southern Netherlands and northern Belgium, between the Late Bronze Age and Early Roman Period (1050-200 AD). The introduction of an extensive agricultural system, the Celtic field system, in co-relation with demographic rise, led to increased anthropogenic pressure on the MDS landscape. Throughout the Holocene, demographic rise pressured farmers to develop increasingly efficient and innovative methods of extracting more yields per unit area farmed resulting in a decrease in land use per capita over time (Kaplan et al. 2010; Boserup, 1965,1981)). The land use per capita under Celtic field technology was relatively high compared to contemporary numbers, based on the assumption that land use per capita did not remain constant. The MDS region is a clear example of early Holocene ALCC and modification of terrestrial ecosystems due to excessive clearance of vegetation. Early Holocene ALCC resulted in ecological deficiencies in the landscape, e.g. deforestation, acceleration of podzolisation and a decrease in terrestrial carbon storage as well as water retention capacity. ALCC can impact climate through biogeophysical and biogeochemical feedbacks to the atmosphere, and result in regional negative radiative forcing. Here we hypothesize that the previously presumed fundamental restructuring that led to a structural bipartition in the landscape due to

The marketing channel was descriptively explained and the quantitatif data were analyzed by: (1 the ratio consentration approach to know the market structure of rubber; (2 the corellation and prize transmission elasticity to know the market conduct of rubber, namely the corelation for the horizontal rubber market integration; the price trasmission elasticity to know vertical rubber market integration; and (3 the marketing margin and profit share to know the marketing peformance. The study result indicate that (1 there were six kinds of rubber marketing cannel, the best of which was the farmer – district wholesaler – exporter channel. This cannel was used by only a few farmers in the area under investigation, thus only a few farmers had good access to the exporter. Most of the farmers marketed their rubber through the medium marketing channel That was the farmer - rural wholesaler - regency wholesaler – exporter channel. The farmers were forced to use this channel because they highly depended on the wholesaler in fulfilling daily needs; (2 the market structure at village level, distric level, and regency level was of middle concentration oligopsony revealing that the farmer only had medium power in influencing the market. The market structure at the exporter level was monopsonic showing that only the exporter had power over the market; (3 the market conduct showed improper integration of rubber price at the markets, both horizontal and vertical; and (4 the market performance showed a relatively big marketing margin and was dominated by a big and uneven profit share. This shows the inefficiency of rubber marketing, harming the low level wholesalers and farmer at the lowest position. Looking at it from the rubber production at farmer level, the market conduct and performance harm the wholesaler at lower level and the farmers at lowest position, because the quality of rubber was lower than the Indonesian standard rubber quality.

    parameters (e.g 226 Ra content) from the measured flux value. This method is very useful, especially in the case, where it is very difficult to collect the tailings for analysis due to soil capping or concretization on the tailings surface. A good linear co-relation was observed between 226 Ra contents and radon fluxes in the tailings with a slope of (8.2 ± 0.4) x 10 -4 kgm -2 s -1 . This slope can be used as a conversion factor for the quick estimation of radon flux (Bq m -2 s -1 ) using 226 Ra (Bq kg -1 ) in the U tailings or vice versa. The radon fluxes measured over the tailings pile were: 3.24 ± 2.08, 3.07 ± 1.76 and 3.54 ± 1.83 Bq m -2 s -1 in summer, winter and rainy seasons respectively with seasonal average of 3.28 ± 1.09 Bq m -2 s -1 . Considering the area of the tailings pile (TP-1), the radon source term is calculated as 8.07 x 10 13 Bq y -1 . The source term will be very useful in future for modeling the radon dispersion in the villages surrounding the U tailings pile

    Magmatic C-O-H volatiles influence the evolution of planetary atmospheres and, when precipitated and stored in solidified mantles, the dynamical evolution of planetary interiors. In the case of the Earth, the fO2 of the mantle near the end of core formation should have been ~IW-2, and subsequently increased to present-day values [1]. In experiments with fO2 ≤ IW, a variety of reduced volatile species have been found dissolved in magmas, including H2, CH4, CO, Fe(CO)5 and possibly Fe(CO)62+. However, there remains significant disagreement regarding the identity and concentrations of these volatiles in natural magmas, as well as their dependencies on intensive variables (T, P, fO2, fCO, fH2)[2-6]. Previous experiments document the importance of CO-related species [2,6], but were conducted over a limited range of fCO and had potentially interfering effects from poorly controlled variations in H2O. We aim to experimentally determine the solubility of C-O-H volatiles in basaltic magmas under reduced, C-saturated conditions while minimizing water content. The relationship between volatile speciation, fO2, and fCO at 1.2 GPa and 1400°C are constrained, laying the groundwork for a more extensive study at a range of conditions relevant to the interiors of the terrestrial planets and the moon. Both MORB and a martian basalt were studied, contained in Pt-C capsules with Fe × Pt × Si metal added to generate reducing conditions and to monitor fO2. A nominal amount of H2O is unavoidable in experimental charges, but was minimized by drying capsules prior to welding. Phase compositions were determined by electron microprobe and volatile concentrations were measured by FTIR spectroscopy. In preliminary experiments with fO2 of IW-0.70 to +1.75 (corresponding to log fCO of 3.3-4.5), H2O and CO2 concentrations as determined by FTIR are 113-13283 and 12-721 ppm, respectively. Most experiments also display a small FTIR peak at 2205 cm-1, whereas the most reduced experiments lack

    key words: gas chromatography, trace gases, CFCs and SF6 measurements in urban area. Halogenated compounds (chlorofluorocarbons-CFCs), both natural and industrial, so-called freons, currently exist as trace gases in the entire human environment. The CFCs cause ozone depletion in the stratosphere. Moreover CFCs and SF6 take part in intensification of the greenhouse effect. The decisions of the Vienna Convention (1985) and of the Montreal Protocol (1987) limited the world production level of CFCs in the year 1989 at least 35% after 2004, 90% after 2015 and total reduction after year 2030. On account of international agreements, the measurements of CFCs and SF6 in air were started. Measurement "clean" stations were situated at places outside of urban areas influence and gathered on world program - AGAGE (Advanced Global Atmospheric Gases Experiment). One of these stations is Mace Head (Ireland, 53o N, 10o W), which participates in AGAGE since 1987 [1] and in European InGOS (Integrated non-CO2 Greenhouse gas Observing System) program since 2011. Similar research is also conducted in Central Europe, in urban area of Krakow (Poland, 50o N, 19o E) since 1997. The work discusses results from 15 years of concentration measurements (in the years 1997-2012) of selected halocarbons and SF6 in Krakow. To obtain concentrations of measured compounds the mathematical procedure has been used, where concentrations were calculated using a five points Lagrange's interpolation method. Using temporary measurement data were determined daily arithmetic means and their standard deviations. Based on these data, efficiency of Montreal Protocol legislation, implemented in Poland (The Journal of Laws No. 52) could be assessed [2]. Additionally cut-off filtration method was used to estimate trend of the base line of individual air pollutant. Rejected exceedances of base lines were corelated with meteorological characteristics of Krakow region to evaluate possible sources of pollution. The

Eight teachers responded regarding the participation of nine students with disabilities through the use of the SFA and a questionnaire. The results indicated that, for five teachers, SFA helped with the perception of the student's participation, focusing on the activity demand and brought reflections on: the need of evaluation not just in the classroom, co-relation between the degree of disability and the participation of the student, understanding of the specificities of the performance, importance of the adaptation to neutralize incapacity and the importance of the focus deviation from the disability toward functionality.

We consider that the descriptive research observes, registers, analyses and co-relates facts or phenomena without manipulating them; such approach helps us to discover the frequency in which a phenomenon happens, the connection of the phenomenon with the others, and also its nature and characteristics. Since the first results of our scientific investigation we have identified that the legends seen by the students in their classroom have potentized the popular imaginary and have maintained the cultural identity of a religious manifestation. We consider that the teachers of religious teaching can introduce this teaching methodology proposed in their school plans. Keywords: Legends. Imagination. Education.

    The close relationship between crustal magmatism, an expression of heat dissipation, and tectonics, an expression of stress dissipation, leads to the question of their mutual relationships. Indeed, the low viscosity of magmas and the large viscosity contrast between magmas and surrounding rocks favor strain localization in magmas, and then possible "magmatic" initiation of structures at a wide range of scales. However, new data about 3-d pluton shape and duration of pluton construction perturb this simple geological image, and indicate some independence between magmatism and tectonics. In some cases we observe a direct genetic link and strong arguments for physical interactions between magmas and tectonics. In other cases, we observe an absence of these interactions and it is unclear how magma transfer and emplacement are related to lithospheric-plate dynamics. A simple explanation of this complexity follows directly from the pulsed, incremental assembly of plutons and its spatial and temporal characteristics. The size of each pluton is related to a magmatic pulsation at a particular time scale, and each of these coupled time/space scales is related to a specific process: in small plutons, we can observe the incremental process, the building block of plutons; in larger plutons, the incremental process is lost, and the pulsation, which consists of a cycle of injections at different timescales, must be related to the composition and thermal regime of the source region, itself driving magmatic processes (melting, segregation, and transfer) that interact with tectonic boundary conditions. The dynamics of pulsed magmatism observed in plutonic systems is then a proxy for deep lithospheric and magmatic processes. From our data and a review of published work, we find a positive corelation between volume and duration of pluton construction. The larger a pluton, the longer its construction time. Large/fast or small/slow plutons have not been identified to date. One

    behavioral desire. Also important impact of this factor on prevolitional stages of aggressive behavior was identified. Next important predictor of behavioral desire was anticipation of positive emotions, but not negative emotions. These results correspond with theory of self-regulation where behavior that is focused on goal attainment is accompanied with positive emotions (see for example Cacioppo, Gardner & Berntson, 1999, Carver, 2004. Results confirmed not only sufficient model fit, but also explained 53% of variance of behavioral desire, 68% of intention and 37% of behavior. Some limitations should be mentioned - especially unequal gender representation in the second sample. Some results could be affected by lower sample size. For the future we recommend use also other types of aggressive behavior in verification EMGB and also to apply more complex incorporation of inhibition to the model. At last, character of this study is co-relational, therefore further researches should manipulate with key variables in experimental way to appraise main characteristics of stated theoretical background.

    topic which is often associated with the incidence of Acute Coronary Syndrome (ACS in the world, especially hyperglicemia on hospital admission. This is due to several effects of high random blood glucose to the cardiocasculer system for instance impaired left ventricular function, decreased stroke volume, reccurrent mitral valve regurgitation, impaired diastolic filling, high risk arrhytmias and its corelation with the increase thrombosis risk. This circumstance explains more about the effects of hyperglicemia that not only increase the risk of Acute Coronary Syndrome (ACS, but can also worsen the Acute Coronary Syndr
