Oral health-related quality of life among Belgrade adolescents

Background/Aim. Adolescents are vulnerable group in term of acquisition of oral health-related knowledge, habits and attitudes. That is why the aim of this study was to investigate the associations between dental status, dental anxiety and oral health-related behavior and oral health-related quality of life as captured by Oral Impacts on Daily Performances (OIDP) index. Methods. This cross-sectional survey included representative sample of 404 adolescents (15 years old), randomly recruited from high schools in Belgrade, Serbia. The adolescents were inter-viewed using Serbian versions of eight-item OIDP index, Hiroshima University Dental Behavior Inventory (HU-DBI) and modified Corah’s Dental Anxiety Scale (MDAS). Three previously trained and calibrated dentists examined the subjects in the classrooms to determine the oral health status of adolescents [the Decayed, missing, filled teeth (DMFT) index and visual signs of gingivitis]. Results. At least one oral impact was reported in 49.50% of adolescents. Most frequently, oral health problems affected eating (26.73%), tooth cleaning (27.47%) and sleep and relaxation (16.83%). In comparison with adolescents without oral impacts, the adolescents with at least one oral impact reported, had higher DMFT score, more often reported problems with bleeding gums, usage of hard toothbrush, worries about the color of their teeth and seeing the dentist because of the symptoms. Logistic regression showed that dental anxiety (MDAS score), dental behavior (HU-DBI score) and worrying about the color of the teeth significantly affected OIDP score. Conclusion. Oral health-related quality of life among adolescents was affected by their behavior and dental anxiety levels. Implementing public health policies that target adolescents with poor oral health or bad habits might be helpful in improving their oral health-related quality of life.
INTEGRAL COMPARISON THEOREMS FOR THIRD ORDER LINEAR DIFFERENTIAL EQUATIONS

By means of a change of variable in the Riccati equation corresponding to the third order linear equation Ly = y'"+p(t)y'+q(t)y = 0 a, nonlinear integral equation is obtained which has a solution obtainable by successive approximations under certain conditions on p and q. This technique allows one to obtain new sharp comparison theorems for Ly=0. Several examples are given to illustrate the results.
Most Probable Producing Ability of Bali Cows for Calving Interval and Calf Growth Performance

Most probable producing ability (MPPA) is the one factor used to compare the performance potential of dam based on the data of their progeny. The purpose of the research was to study the genetic ability of weaning weight, yearling weight and calving interval of Bali cows. The weaning weight data of 296 cows derived from 99 dams, yearling weight data of 245 cows derived from 86 dams and calving interval data of 194 cows from 63 dams were used to estimate repeatability and MPPA of Bali cows in a herd for the three traits. Repeatability of three traits was estimated by analysis of intra-class correlation, and these in turn were used for calculating the estimated MPPA of cows. The results showed that the means of weaning weight of males and females were 95.56 ± 17.25 kg and 87.57 ± 18.45 kg, respectively; means of yearling weight were 143.39 ± 25.78 kg and 136.90 ± 22.01 kg, respectively; and mean calving interval was 391.62 ± 22.59 d. The estimated repeatability of weaning weight, yearling weight and calving interval were 0.006 ± 0.059, 0.022 ± 0.068 and 0.115 ± 0.078, respectively. The best 10 dams in the herd based on the estimates of MPPA for weaning weight, yearling weight and calving interval were not the same for the three traits.
Hepatoprotective Herbs – A Review

Liver is a vital organ play a major role in metabolism and excretion of xenobiotics from the body. Liver injury or liver dysfunction is a major health problem that challenges not only health care professionals but also the phar-maceutical industry and drug regulatory agencies. Liver cell injury caused by various toxic chemicals (certain anti-biotic, chemotherapeutic agents, carbon tetrachloride (CCL4), thioacetamide (TAA) etc.), excessive alcohol con-sumption and microbes is well-studied. The available synthetic drugs to treat liver disorders in this condition also cause further damage to the liver. Hence, Herbal drugs have become increasingly popular and their use is wide-spread. Herbal medicines have been used in the treatment of liver diseases for a long time. A number of herbal preparations are available in the market. The present review is aimed at compiling data on promising phytochemi-cals from medicinal plants that have been tested in hepatotoxicity models using modern scientific system. Keywords: Herbal drugs, Liver Injury, Carbon tetrachloride (CCL4), Hepatotoxicity, Serum transaminases.
Aerosol Observation with Raman LIDAR in Beijing, China

Aerosol observation with Raman LIDAR in NIES (National Institute for Environmental Studies, Japan) LIDAR network was conducted from 17 April to 12 June 2008 over Beijing, China. The aerosol optical properties derived from Raman LIDAR were compared with the retrieved data from sun photometer and sky radiometer observations in the Aerosol Robotic Network (AERONET). The comparison provided the complete knowledge of aerosol optical and physical properties in Beijing, especially in pollution and Asian dust events. The averaged aerosol optical depth (AOD) at 675 nm was 0.81 and the Angstrom exponent between 440 nm and 675 nm was 0.99 during experiment. The LIDAR derived AOD at 532 nm in the planetary boundary layer (PBL) was 0.48, which implied that half of the total AOD was contributed by the aerosol in PBL. The corresponding averaged LIDAR ratio and total depolarization ratio (TDR) were 48.5sr and 8.1%. The negative correlation between LIDAR ratio and TDR indicated the LIDAR ratio decreased with aerosol size because of the high TDR associated with nonspherical and large aerosols. The typical volume size distribution of the aerosol clearly demonstrated that the coarse mode radius located near 3 lTEXg${\mu}m$l/TEXg in dust case, a bi-mode with fine particle centered at 0.2 lTEXg${\mu}m$l/TEXg and coarse particle at 2 lTEXg${\mu}m$l/TEXg was the characteristic size distribution in the pollution and clean cases. The different size distributions of aerosol resulted in its different optical properties. The retrieved LIDAR ratio and TDR were 41.1sr and 19.5% for a dust event, 53.8sr and 6.6% for a pollution event as well as 57.3sr and 7.2% for a clean event. In conjunction with the observed surface wind field near the LIDAR site, most of the pollution aerosols were produced locally or transported from the southeast of Beijing, whereas the dust aerosols associated with the clean air mass were transported by the northwesterly or southwesterly winds.
Yield and competition in barley variety mixtures

Competition between spring barley varieties and yield performance of two-, threeand four-variety mixtures were studied in two replacement series field experiments. In the first experiment, repeated in three successive years (1983 —85) the components were the six-row varieties Agneta, Arra, Hja-673 and Porno. In the second experiment (1984), including two nitrogen doses (50 and 100kgN/ha), both six-row (Agneta, Pomo) and two-row (Ida, Kustaa) varieties were used. Arra in the first and Agneta in the second experiment were the most competitive varieties. The results suggested that the fast growth of Arra at the beginning promoted its competitive ability. Increase in available nitrogen usually strengthened the competitiveness ofAgneta. The observed competitive differences between varieties were not related to the earliness of a variety, neither to the morphological characters (twoand six-row varieties) nor to the grain yield of a variety grown alone. The competitive ability was not always a stable character, the dominantsuppression relationship varying from one environment to another (e.g. growing season, nitrogen dose). The observed overyielding was not statistically significant. The ratio of actual to expected yield and the relative yield total of several mixtures exceeded slightly one. As a conclusion, the yield advantage of mixtures was marginal. As a rule, the mixtures were not more stable than monocultures as determined by the coefficient of variation. However, the yield of some mixtures varied less than the yield of the most stable monoculture. Index words: Competition, yield, barley, mixture
UNCERTAINTIES IN ANALYSING THE TRANSFERABILITY OF THE GENERIC

The Generic Slum Ontology (GSO) was developed to assist the detection of slums using Geographic Object-Based Image Analysis (GEOBIA). When applying the GSO locally, uncertainties exist in slum detection and transferability. Slums often have fuzzy boundaries and different ways to conceptualise. This study focuses on inherent uncertainties when analysing the transferability of the GSO across space, time and conceptualizations in the city of Jakarta, Indonesia. To measure the transferability of the GSO, we developed quantitative and qualitative indicators in multi-temporal Pleiades imagery (2012-2015) of two purposely-selected subsets. This framework allows assessing whether the developed ruleset is transferable across different spatial and temporal images. We applied two classification stages: background removal with a low scale parameter (SP) followed by slum extraction with a coarser SP. Both quantitative and qualitative indicators showed limited spatial and temporal transferability. Three sources of uncertainties can explain this result. First, the static concept of the employed ruleset and dynamic changes of slums. Real-world objects evolve over time, but their description remains static. Second, the gap between the real world (subjective conceptualization of objects) and image domain (quantitative values). For instance, the roof materials of slums (i.e. asbestos) have a similar spectral property with parking lot (from concrete), which resulted in misclassification. Third, the use of references data from local experts and municipal data introduce uncertainties that related to local ground knowledge and politics of slum declarations. Thus, this research contributes to the development of transferability measurements for the GSO and the understanding of underlying uncertainties. * Corresponding author
Molecular Detection of gyrA, parC and oprD Mutation in Pseudomonas aeruginosa Isolates from a University Hospital of Isfahan, Iran during 2016

Background : Excessive use of broad-spectrum antibiotics in hospitals has led to the emergence of highly resistant strains of Pseudomonas aeruginosa . The main mechanism of resistance of this bacterium to fluoroquinolones and carbapenems are the modification of type II topoisomerases (DNA gyrase and topoisomerase IV) and alterations in the OprD porin, respectively. The aim of this study was to examine for the occurrence of mutations related to fluoroquinolone resistance of gyrA and parC genes and mutational inactivation of oprD gene of clinical isolates using DNA sequencing technique. Methods : A total of 60 P. aeruginosa isolates were collected from the hospitalized patients in the Intensive Care Units (ICUs) of Al-Zahra hospital located in Isfahan, Iran. The pattern of sensitivity to antibiotics was determined using CLSI disk diffusion and MIC methods. The assay was based on a DNA sequencing method using polymerase chain reaction (PCR) for amplification and sequencing of the selected genes. Results : The results show that replacement of Ile for Thr-83 in gyrA was the only replacement, while other substitutions not observed. No mutations were found in parC . The most frequent amino acid alterations were E185Q, P186G, and V189T, found in five resistance isolates, However, nucleotide insertions and deletions mutations not observed. Conclusion : Our study suggested that mutation of gyrA and oprD genes may play a minor role in fluoroquinolone and carbapenem resistance and other mechanisms may contribute to the fluoroquinolone and carbapenem resistance of P. aeruginosa .
Supplier segmentation from the perspective of internal knowledge sharing: A case study in the retailing business

Supplier segmentation is identified to be a crucial part of supplier relationship management. Yet, no specific study concerning supplier segmentation in the retailing business has been accomplished. As the retailing landscape is changing rapidly, and the management of supplier relationships getting more and more complicated – there is a need to address this gap in the literature. The aim of this thesis is to explore the supplier segmentation process in the retailing context, and to construct a typology of it. The exploration takes a perspective of knowledge sharing, as it is identified to be closely connected with supplier relationships and thus supplier segmentation. Five elements are identified, based on the literature, to construct the actual supplier segmentation process; sourcing strategy, supplier information, segmentation, outcome of segmentation and improvement. These are elaborated in the conceptual framework, which structures the data gathering of this thesis. Data is gathered through several observations and semi-structured interviews within the case company, Kesko. Findings from these represent two business areas, the grocery trade and the building and technical trade – as well as two countries; Finland and Poland. This thesis identified that suppliers in a retailing company are segmented for multiple different needs, and that none of the models covers all of the needs. It was further noted that the more complex the organization in a retailing company is, the greater the amount of knowledge sharing barriers regarding supplier information there are. Thereby, this drives for an internal knowledge sharing platform allowing to create different segments of suppliers. It was identified that an internal knowledge sharing platform can make the segmentation process faster and more accurate, which allows better external knowledge sharing as well.
Idiosyncratic Risk Pricing in Canada

This paper confirms the relationship between idiosyncratic risk and excess stock returns for Canadian equities. The relationship between returns and idiosyncratic risk is examined using Fama-MacBeth twostep methodology with a modified Carhart four-factor (five-beta) model. The Fama-MacBeth tests are conducted with and without the presence of control variables for liquidity (proxied by amortized spread or the illiquidity measure of Amihud) and firm-specific information embedded in stock prices (proxied by synchronicity and the zero-return&trade metric). The conditional relation between returns and idiosyncratic risk for Canadian stocks is robust and significant. Given the model dependencies and metrics, the paper posits this to a higher competitive environment, investor under-diversification, and lower market power faced by Canadian firms as compared to US firms.
Destructive Diversity, Inflationary Convergence and the Inflation Criterion: The Way to EMU Reconsidered

Since the signing of the Maastricht Treaty, there has been an intensive discussion whether the convergence criteria incorporated into the contract were appropriate to prepare the EU-member-countries for European Monetary Union. We argue that at least inflationary convergence was not a necessary precondition for EMU. This paper aims at analyzing the effects of the inflation criterion with regard to its possible influence on welfare of the EU-member-states during the transitional phase (stage II). It is shown that the inflation criterion can be interpreted as a component of an incentive compatible contract; insofar it has contributed to a decrease in inflation bias during stage II of EMU but played no important role with respect to stage III.
Factors Affecting the Joint Adoption of Herbicides and Conservation Tillage Technologies among Smallholder Farmers in Zambia

For over three decades, Zambian private and public organizations have been promoting Conservation Agriculture (CA) among smallholder farmers, throughout the country. CA, as a technology, involves Conservation Tillage (CT) methods and use of herbicides, particularly in the first 3 to 4 years of its adoption. Despite the long-term CA dissemination effort from stakeholders, adoption of both herbicides and CT technologies has been relatively low. Using the 2012 Rural Agricultural Livelihood Survey (RALS12) data collected country-wide, a bivariate probit analytical model investigated whether Zambian smallholder farmers make a joint adoption decision in the uptake of herbicides and CT methods. Results indicate that the adoption of herbicides is jointly linked to the adoption of CT technologies. Factors such as being a male-headed household, belonging to a cooperative society, larger sizes of cultivated areas, owning productive tools such as a knapsack sprayer and receiving advice on CA technologies, were critical in positively influencing the joint-adoption of herbicide and CT technologies. Overall, results imply that if the adoption of herbicides is to be enhanced, the promotion of CT technologies have to be intensified. The best promotional channels include agricultural groups such as farmer cooperatives, which are good conduits and platforms for smallholder farmers’ knowledge-sharing. These promotional efforts should support gender balancing and emphasize the inclusion and use of herbicides in CA. There is also need for government to enhance farmers’ access to productive tools that support the use of herbicides such as knapsack sprayers.

The present study was an attempt to examine the learning environment and the intellectual variables of grades 8 and 11 classes from rural and urban settings representing mathematics, science, social studies, and English courses. Ninety-six classrooms provided the data. Significant multivariate main effects were obtained on locale (rural and urban) and grade (8 and 11). Significant multivariate main effects and interactions are discussed in relation to the previous research and theory. Specific educational implications of the results of the present study are pointed out.
Impact of cyanobacterial toxins (microcystins) on growth and root development of in vitro Vicia faba cultures

The occurrence of toxic freshwater blooms of cyanobacteria has been frequently reported during the last 15 years in Lalla Takerkoust lake (35 km southwestern of Marrakech city) In this study, it has been confirmed that the collected cyanobacteria bloom could produce different variants of microcystins at high concentration of 11.5 mg equiv. MC-LR g-1DW of the cyanobacteria cells. In order to study the effect of microcystins on faba bean seedling cultured in vitro, the crude aqueous extract of the toxic bloom was prepared and sterilized by filtration, and then it was supplemented to BNM medium at different concentrations. After 10 days of in vitro seedlings growing in BNM medium, plants fresh and dry weights were determined, plants shoot and root length was measured and then the roots were subjected to histological microscope observation of root hair, root tip and root cortical cells. The results revealed that microcystins exposure induced a decreasing of seedling growth and biomass accumulation in a concentration dependent manner. In addition, seedling young roots exhibited a brownish aspect, necrosis and tissue lysis. At a microcystin's concentration of 40
The interplay between the surface and bottom water environment within the Benguela Upwelling System over the last 70 ka

The Benguela Upwelling System (BUS), located between 30 and 20°S, is one of the fundamental high-productivity systems of the world ocean. The BUS has previously been studied in terms of primary productivity and ecology over glacial-interglacial timescales; however, the response and coupling with the benthic environment have received little attention. Here, for the first time, we present a high-resolution reconstruction of the BUS highlighting the link between surface and benthic productivity and their response to climatic and oceanographic changes over the last 70 ka. The study is based on benthic foraminiferal faunal analysis together with analyses of diatom assemblages, grain size of the terrigenous fraction, and stable O and C isotopic and bulk biogenic components of core GeoB3606-1. We reveal significant shifts in benthic foraminiferal assemblage composition. Tight coupling existed between the surface and bottom water environment especially throughout marine isotope stages 4 and 3 (MIS4 and MIS3). Due to the high export production, the site has essentially experienced continuous low oxygen conditions; however, there are time periods where the hypoxic conditions were even more notable. Two of these severe hypoxic periods were during parts of MIS4 and MIS3 where we find an inverse relationship between diatom and benthic foraminifera accumulation, meaning that during times of extremely high phytodetritus export we note strongly suppressed benthic productivity. We also stress the importance of food source for the benthos throughout the record. Shifts in export productivity are attributed not only to upwelling intensity and filament front position, but also, regional-global climatic and oceanographic changes had significant impact on the BUS dynamics.
Biocompatibility of anionic collagen matrices and its influence on the orientation of cellular growth.

This study aimed to analyze the biocompatibility of anionic collagen matrices, the local bone response following implantation in surgically-created bone defects, and also the influence of the collagen fiber orientation on the neoformed osseous tissue. Seventy two rats (Rattus norvegicus albinus) were used in this experiment. The animals were divided into four experimental groups: Group 1 (control), without implants; Group 2, pericardium medullar implants 12 hours; Group 3, medullar implants of tendon 24 hours, with the long axis of collagen fibers oriented parallel to the long axis of the tibia; and Group 4, medullar implants of tendon 24 hours, with the long axis of collagen fibers perpendicular to the long axis of the tibia. After the experimental surgery, the evolution of the repair process was microscopically evaluated at 7, 15, and 30 days post-surgery. The results demonstrated that the mplanted matrices are biocompatible and act as a scaffold inducing bone formation, mainly in the Group 4 animals. At first, cellularity follows the arrangement of collagen fibers, later obtaining a multidirectional growth.
Polynomially bounded solutions of the Loewner differential equation in several complex variables

‎We determine the‎ ‎form of polynomially bounded solutions to the Loewner differential ‎equation that is satisfied by univalent subordination chains of the‎ ‎form $f(z,t)=e^{int_0^t A(tau){rm d}tau}z+cdots$‎, ‎where‎ ‎$A:[0,infty]rightarrow L(mathbb{C}^n,mathbb{C}^n)$ is a locally‎ ‎Lebesgue integrable mapping and satisfying the condition‎ ‎$$sup_{sgeq0}int_0^inftyleft|expleft{int_s^t‎ ‎[A(tau)-2m(A(tau))I_n]rm {d}tauright}right|{rm d}t 0$ for $tgeq0$‎, ‎where‎ ‎$m(A)=min{mathfrak{Re}leftlangle‎ ‎A(z),zrightrangle:|z|=1}$‎. ‎We also give sufficient conditions‎ ‎for $g(z,t)=M(f(z,t))$ to be polynomially bounded‎, ‎where $f(z,t)$ is‎ ‎an $A(t)$-normalized polynomially bounded Loewner chain solution to‎ ‎the Loewner differential equation and $M$ is an entire function‎. ‎On ‎the other hand‎, ‎we show that all $A(t)$-normalized polynomially‎ ‎bounded solutions to the Loewner differential equation are Loewner‎ ‎chains. ‎
