Evaluation of AHRS algorithms for Foot-Mounted Inertial-based Indoor Navigation Systems
Authors: Li Xin , Wang Yang
Published: March 2019

Personal Dead Reckoning based on foot-mounted Inertial Measurement Units is a research hotspot in the field of positioning and navigation in recent years. This paper conducts a targeted research on the application of current mainstream attitude and heading reference system (AHRS) algorithm in the foot inertial navigation positioning. Through open datasets, the positioning accuracy and directional accuracy of 9-state complementary Kalman filter (CKF) are compared and analyzed among the conventional algorithm, Mahony algorithm, and Madgwick algorithm, in which the Madgwick algorithm can achieve the best positioning results. And on this basis, for the Madgwick algorithm, it is verified that it can help improve the positioning accuracy of 15-state CKF under the assistive technologies of zero angular rate update (ZARU) and heuristic heading reduction (HDR). The adaptive zerospeed detection algorithm is designed, and the threshold value of zero-speed detection is set dynamically through tracking the variable of speed in CKF, which can detect the time period of zero-speed state more accurately, thus further improving the correction of directional errors. Finally, the effectiveness of the proposed algorithm is further proved by actual data.

Published: March 2019

Background

Infertile women may have underlying genetic abnormalities. There is, at present, a significant number of studies on the relation between the follicle stimulating hormone receptor (FSHR) or anti-Müllerian hormone type II receptor (AMHRII) polymorphisms and response to in-vitro fertilisation (IVF) treatment. However, it is not yet clear which genotype or combination of genotypes is favourable towards a better ovarian stimulation and pregnancy outcome.

Materials and methods

In this study we assessed the distribution of the genotypes of FSHR Ser680Asn and of AMHRII −482A>G gene polymorphisms in a group of 126 infertile women and a control group of 100 fertile women by using real-time polymerase chain reaction (RT-PCR).

Results

Statistical analysis showed that the frequency of the genotypes is similar in both control and IVF/ intracytoplasmic sperm injection (ICSI) groups. Further investigation of the frequency of the nine possible combinations of these polymorphisms in the groups revealed no correlation between infertility and combination of the polymorphisms. Women with one polymorphism have on average 5.5 units higher levels of AMH compared to women carrying no polymorphism. In women with no polymorphisms, for each unit of FSH increase, the average concentration of blood AMH is expected to be 72% lower.

Conclusion

The distribution of the FSHR Ser680Asn and of the AMHRII −482A>G gene polymorphisms, in the Greek population is similar in fertile and infertile women. The study showed that FSH and AMH correlated levels in certain cases could be used to estimate a patient’s ovarian reserve.

Toxic metals, including excessive levels of essential metals tend to change biological structures and systems into either reversible or irreversible conformations, leading to the derangement of organ functions or ultimate death. Nickel, a known heavy metal is found at very low levels in the environment. Nickel is available in all soil types and meteorites and also erupts from volcanic emissions. In the environment, nickel is principally bound with oxygen or sulfur and forms oxides or sulfides in earth crust. The vast industrial use of nickel during its production, recycling and disposal has led to widespread environmental pollution. Nickel is discharged into the atmosphere either by nickel mining or by various industrial processes, such as power plants or incinerators, rubber and plastic industries, nickel-cadmium battery industries and electroplating industries. The extensive use of nickel in various industries or its occupational exposure is definitely a matter of serious impact on human health. Heavy metals like nickel can produce free radicals from diatomic molecule through the double step process and generate superoxide anion. Further, these superoxide anions come together with protons and facilitate dismutation to form hydrogen peroxide, which is the most important reason behind the nickel-induced pathophysiological changes in living systems. In this review, we address the acute, subchronic and chronic nickel toxicities in both human and experimental animals. We have also discussed nickel-induced genotoxicity, carcinogenicity, immunotoxicity and toxicity in various other metabolically active tissues. This review specifically highlighted nickel-induced oxidative stress and possible cell signaling mechanisms as well.
Twenty Years of European Central Bank Monetary Policy: A Keynesian and Austrian Perspective
Authors: van Riet Ad
Published: March 2019

This article reviews how the European Central Bank (ECB) implemented its monetary policy for the euro area from 1999 to 2018 from two perspectives. Taking a Keynesian point of view, the euro area economy was beset for a long time by secular stagnation and required the ECB to ensure a protracted period of relatively low interest rates to provide continuous support to aggregate demand at the level of the Economic and Monetary Union (EMU). By contrast, the Austrian School of Economics argues that the low-interest rate bias of the ECB caused financial excesses and prevented a more rapid reallocation of unviable resources necessary for a sustainable expansion of aggregate supply. Both the Keynesian and the Austrian paradigm appear relevant when examining the monetary and financial aspects of the euro area business cycle and the secular decline of interest rates over the past 20 years. For most of the time, ECB monetary policy was the ‘only game in town’ and the EMU architecture was unable to deliver the balanced macroeconomic and financial policy mix required for a sustainable path of the euro area economy.
Terminal Value in SMEs: Testing the Multiple EV/EBITDA Approach
Authors: Vidal-Garcia Raül , Ribal Javier
Published: March 2019

This study focuses on answering whether EV/EBITDA multiple of public companies in the food industry can be useful to obtain the Terminal Value (TV) in the valuation of unlisted small and medium-sized food companies. A case study into Spanish unlisted agribusinesses is designed for several samples and accounting years from 2010 to 2013. By means of a discounted cash flow (DCF) model combined with bootstrap techniques, the TV/EBITDA empirical distribution of the unlisted multiples is obtained for two different scenarios of free cash flow (FCF) growth, and then compared with the EV/EBITDA of the listed companies in the same industry. The results show that the stock market EV/EBITDA multiple may be used to determine the TV in the valuation process of unlisted small and medium-sized food companies that consistently obtain positive cash flows.
How many indicator species are required to assess the ecological status of a river?
Authors: Budka Anna
Published: March 2019

The presented research focused on macrophytes, which constitute a primary element in the assessment of the ecological status of surface waters following the guidelines of the Water Framework Directive. In Poland, such assessments are conducted using the Macrophyte Index for Rivers (MIR). The objective of this study was to characterize macrophyte species in rivers in terms of their information value in the assessment of the ecological status of rivers. The macrophyte survey was carried out at 100 river sites in the lowland area of Poland. Botanical data were used to verify the completeness of samples (the number of taxa). In the presented research, the information provided by each species was controlled. Entropy was used as the main part of information analysis. This analysis showed that the adoption of a standard approach in the studies of river macrophytes is likely to provide sample underestimation (with missing species). This may potentially lead to incorrect determination of MIR and thus result in a wrong environmental decision. On this basis, a sample completeness criterion was developed. Using this criterion, the average value of information for macrophyte species in medium-sized lowland rivers is suffcient to be considered representative.

Published: March 2019

Madagascar is an isolated island characterized by a high degree of endemism at all taxonomic levels. Diatom assemblages of the region are still poorly known and sporadic sampling events in various habitats (e.g. lagoons, mangroves) have revealed a large number of taxa that could not be identified. This study presents detailed descriptions of two new species of Luticola: L. nosybeana and L. madagascarensis, collected from mangrove roots on Nosy Be Island. Comparisons with the described congeners showed that the density of striae in Luticola nosybeana is higher than that in L. belawanensis and proximal raphe endings terminate as irregular, shallow grooves. Luticola madagascarensis differs from L. similis in the shape of proximal raphe endings, which are short and expanded in the latter, while continue with irregular, shallow, elongated L-shaped grooves in L. madagascarensis. Luticola nosybeana and L. madagascarensis can be distinguished under a light microscope by the shape of the central area (bow-tie shaped in L. madagascarensis and deltoid in L. nosybeana) and isolated pores (robust and well visible in L. madagascarensis, poorly discernible in L. nosybeana). The two new species are unique in their habitat preferences: while all known congeners are freshwater, the new species inhabit estuarine mangroves.

Published: March 2019

In this study, we conducted a comparative analysis of the abundance and diversity of bacteria on the surface of the submerged macrophyte Myriophyllum spicatum, as well as in the surrounding water column and sediment in the low-salinity area of Hangzhou Bay, China. Bacterial clones from three clone libraries were classified into 2089 operational taxonomic units (OTUs), most of which affiliated with bacterial divisions commonly found in marine ecosystems. Alphaproteobacteria, Cyanobacteria and Gammaproteobacteria were the most abundant groups of bacteria on the surface of plants, in the water column and sediment, respectively. Epiphytic bacterial communities were more closely related to those in the sediment than bacterioplankton, and some species of epiphytic bacteria were found only on the surface of M. spicatum. The relative abundance of epiphytic bacterial genera associated with breakdown of organic compounds and with cellulose digestion was higher in October than that in July. These results suggested that bacterial communities on the surface of M. spicatum may originate from sediment bacterial communities and their specific structure was gradually formed on the surface of M. spicatum after being cultivated in low-salinity seawater.

Published: March 2019

The round goby, Neogobius melanostomus, is a Ponto-Caspian fish species currently found in many parts of Europe, including the North Sea riverine deltas. The objective of this study was to examine the parasite community of fish caught in the lower Elbe (Süderelbe – tidal zone; Geesthacht – non-tidal) in Germany and compare it with published data from the upper Elbe (Ústí nad Labem) in the Czech Republic. Twelve parasite taxa were recorded in the lower Elbe, six in the Süderelbe and nine near the city of Geesthacht. Süderelbe fish were mainly infected with Angullicola crassus larvae, while gobies from Geesthacht – with glochidia and sporadically occurring Pomporhynchus laevis, and the opposite situation was observed at Ústí nad Labem. It appears that a large tidal weir at Geesthacht significantly contributes to the division of the round goby population, with the Geesthacht parasite community being more similar to that at Ústí nad Labem than the one from the Süderelbe, thus increasing the likelihood that shipping from Hamburg was the introduction vector to Ústí nad Labem. We also recorded Acanthocephalus rhinensis in the Elbe for the first time, and in a new host – the round goby. Thus, round gobies may represent a new vector for the introduction of this parasite along the Elbe.
Non-indigenous tanaid Sinelobus vanhaareni Bamber, 2014 in the Polish coastal waters – an example of a successful invader

Published: March 2019

The paper reports on the first record of Sinelobus vanhaareni, a non-native tanaid, in the Polish coastal waters (Gulf of Gdansk, southern Baltic Sea). The species was found in the port of Gdynia in 2014, while in 2015–2017 it already colonized the western part of the Gulf of Gdansk, inhabiting mainly hard substrates, including both natural (e.g. boulders) and anthropogenic ones (e.g. vertical concrete piles or walls of offshore structures and breakwaters, horizontal PVC plates and oyster shells used as filling in habitat collectors). During the survey period, S. vanhaareni was found in different seasons of the year (from winter and early spring to autumn), which, combined with the presence of ovigerous females as well as high abundance (up to tens of thousands of individuals per square meter), allows us to assume that the species has already established a population in the Gulf of Gdansk.

Published: March 2019

Unionid mussel species belong to one of the most threatened invertebrate groups on Earth. Biological invasions, especially those by filtering species, are parti cularly harmful to nati ve Unionidae species. In Poland, a significantly disturbing situati on of native Unionidae is observed in thermally polluted aquatic ecosystems. Such water bodies have favorable conditions for the settlement of alien mollusks, including Sinanodonta woodiana or Corbicula fluminea, whose shells can potenti ally be a beneficial substrate for Dreissena polymorpha. The objecti ve of the presented research was to check whether zebra mussels can hinder the invasion of alien species of bivalve mollusks in thermally polluted waters. Our results indicate that with the increase in thermal polluti on associated with the growing invasion of alien species of bivalves, D. polymorpha infestations of clams decrease considerably, which leads to the conclusion that D. polymorpha does not pose a significantnatural threat to bivalves in the lakes under study.
Many faces of arsenic

Published: March 2019

Arsenic (As) is a natural component of the Earth’s crust. Due to its specific properties, arsenic became e.g. the favorite poison in the 19th century in Europe, a component of an effective insecticide and herbicide in agriculture, a specific chemical weapon during World War II and a medication used to treat various diseases. The bad reputation of this element was confirmed after World War II, when arsenic-based chemical weapons were dumped on the seabed and became a potential threat to the marine ecosystem. The wide distribution of arsenic compounds in the environment necessitated the development of technologies aimed at removing arsenic from the aquatic ecosystem. This study provides a detailed overview of the occurrence, distribution and transformation of arsenic species in the aquatic environment.
Building Companionship Between Community and Personal Archiving: Strengthening Personal Digital Archiving Support in Community-Based Mobile Digitization Projects
Authors: Han Ruohua
Published: March 2019

The interconnectedness between personal digital archiving (PDA) and community-based digital archiving provides an entry point for thinking about how to better bridge the two within single projects. Flexibility and sustainability are dimensions that warrant special consideration to support PDA within community-based digital archiving projects. This paper examines the flexibility and sustainability of two community-based mobile digitization projects (Culture in Transit and Georgia HomePLACE DigiKits) in supporting PDA. The assessment shows that the projects are in a good position to support PDA, with only some concerns about ensuring sustainable access to digitization equipment and sufficient guidance in long-term preservation. Drawing from this work, I propose three ways community-based mobile digitization projects can be redesigned to further strengthen their support for PDA without undermining their community-based objectives. The goal of this paper is to demonstrate the value in considering connections and differences between community and personal archiving needs in current and future projects, and calls for further coordination of efforts and collaboration to build better collaboration between community and personal archiving.

Published: March 2019

This article focuses on the work and efforts put forth by the University of Houston’s Recovering the US Hispanic Literary Heritage program (Recovery) to create the first digital humanities center for US Latina/o Research: #usLdh. Recovery is a program to locate, preserve, and make available the written legacy of Latinas/os in the United States since colonial times until 1960. Through 27 years of successful work Recovery has not only been able to inscribe the excluded history of Latinas/os, but also has created an inclusive and vast digital repository that facilitates scholarship in this area of studies. This article focuses on the importance of recovery work in the writing, teaching, and understanding of history and considers how local personal archives have helped to fill in the gaps of mainstream history. We will detail the goals and challenges of this mission, as well as the importance of educating the community in digital methods that preserve and disseminate minority voices.
Identifying Individual and Institutional Motivations in Personal Digital Archiving
Authors: Condron Melody
Published: March 2019

Personal digital archiving (PDA) is a relatively new field. As it has developed, two distinct personas have emerged: the individual person, seeking to capture and archive their own or someone else’s personal digital materials; and the institution—including museums, libraries, and archives—attempting to acquire and manage personal digital materials. In doing so, institutions also advocate for the preservation and management of personal digital archives and digital file management practices held in private hands. However, individuals and institutions make different choices in terms of curation and management, based on skills, knowledge, purpose, function and economics. Understanding these differences can aid institutional support for personal archives, as well as help to build collaborative frameworks to help personal and institutional differences be better understood. This paper identifies the similarities and differences in motivation and approach between individual and institutional practices and perspectives in PDA.

High-throughput assessment of hypothetical zeolite materials for their synthesizeability and industrial deployability
Authors: Salcedo Perez Jose Luis , Haranczyk Maciej , Zimmermann Nils Edvin Richard
Published: March 2019

Zeolites are important microporous framework materials, where 200+ structures are known to exist and many millions so-called hypothetical materials can be computationally created. Here, we screen the “Deem” database of hypothetical zeolite structures to find experimentally feasible and industrially relevant materials. We use established and existing criteria and structure descriptors (lattice energy, local interatomic distances, TTT angles), and we develop new criteria which are based on 5-th neighbor distances to T-atoms, tetrahedral order parameters (or, tetrahedrality), and porosity and channel dimensionality. Our filter funnel for screening the most attractive zeolite materials that we construct consists of nine different types of criteria and a total of 53 subcriteria. The funnel reduces the pool of candidate materials from initially >300,000 to 70 and 33, respectively, depending on the channel dimensionality constraint applied (2- and 3-dimensional vs. only 3-dimensional channels). We find that it is critically important to define longer range and more stringent criteria such as the new 5-th neighbor distances to T-atoms and the tetrahedrality descriptor in order to succeed in reducing the huge pool of candidates to a manageable number. Apart from four experimentally achieved structures (BEC, BOG, ISV, SSF), all other candidates are hypothetical frameworks, thus, representing most valuable targets for synthesis and application. Detailed analysis of the screening data allowed us to also propose an exciting future direction how such screening studies as ours could be improved and how framework generating algorithms could be competitively optimized.

Many studies highlight the health benefits of mushrooms, which are consequently becoming more and more interesting for researchers. The content of amino acids (AA), total phenolic content (TPC), and antioxidative activity (AAc) were determined in wild as well as cultivated mushrooms. The AA included: L-tryptophan (Trp), L-arginine (Arg), L-cysteine (Cys), L-methionine (Met), L-alanine (Ala), L-phenylalanine (Phe), L-lysine (Lys), L-valine (Val), L-glycine (Gly), and L-leucine (Leu). The wild mushrooms: Lactarius piperatus, Amanita caesarea, Lactarius deliciosus, Lycoperdon pyriforme, Macrolepiota procera, and cultivated mushrooms: Agaricus bisporus, Boletus aestivalis, Cantharellus cibarius, Pleurotus ostreatus, and Agaricus bisporus var. avellaneus were investigated in this study. The AA was determined by HPTLC method and quantified with a Camag TLC scanner and WINCAT software by scanning the plates at 540 nm. The TPC was spectrophotometrically estimated as gallic acid equivalents/g of fresh weight according to Folin-Ciocalteu’s method. The radical scavenging activity (RSA) of mushroom extracts was determined by DPPH assay. The highest content of Ala, Gly, Phe, Lys, Val, and Leu was found in Pleurotus ostreatus. The total phenolic content (mg GAE/g) in investigated mushrooms ranged from 1.90 to 35.56, and the % RSA ranged from 43.88 to 90.17. This study promotes the consumption of food rich in bioactive compounds, mushrooms being among such food. Further research on mushrooms from Bosnia and Herzegovina and their benefits in the overall maintenance of human health and protection from age-related diseases is necessary.

Published: March 2019

This paper presents the results of thermal and microstructural analysis of Cu-Al-Ni shape memory alloy before and after heat treatment. After casting, a bar of Cu-12.8 Al-4.1 Ni (wt.%) alloy, obtained by the vertical continuous casting technique, was subjected to a certain heat treatment procedure. Solution annealing was performed at 850 °C for 60 min, followed by water quenching. Tempering was then performed at four different temperatures (150 °C, 200 °C, 250 °C and 300 °C). The microstructural results were obtained by optical and scanning electron microscopy. Thermodynamic calculation of ternary Cu-Al-Ni system under equilibrium was performed using Thermo-Calc 5 software. Phase transformation temperatures were determined by differential scanning calorimetry (DSC). The DSC results show the highest values of transformation temperatures in as-cast state. After solution annealing and tempering, the transformation temperatures show lower values with exceptional stability of Ms temperature (martensite start temperature).

Published: March 2019

Regarding the complexity of Ziegler-Natta catalyst kinetics in polypropylene polymerization, so far, there is no adequate model to determine the best process conditions for predicting average molecular weight and dispersity as the most crucial final product properties index. Consequently, a validated model has been developed which describes the relationship between the kinetic model and the existing gap using the polymer moment balance approach. It was concluded that increasing reaction temperature and hydrogen amount are useful and improve the final product indices to a certain limit, but afterwards they have harmful effects on the indices.

Money politics is a serious problem for the improvement in the quality of democracy in Indonesia. In every election, there has been a shift or variation in the pattern of money politics. This article answers the important question of what pattern of money politics applied in the 2014 elections was. This study found that the pattern was more complex and that it involved more actors between not only candidates and voters, but also the election organizers. A case study had been used to view the pattern of money politics in the legislative elections in Surabaya and Sidoarjo during the 2014 election. This study explains the connectivity between the emergence of pragmatic-rational voters, the engagement of the party oligarchy in moving the political party machinery and the covert dealings with the election organizer.
Combining Clientelism and Incumbency Advantage: Political Strategy in Candidate Selection for the 2017 Local Head Election in Bekasi Regency
Authors: Paskarina Caroline , Hermawati Rina , Yunita Desi
Published: March 2019

This article discusses the post-clientelist initiatives used by political parties in the selection of candidates within the party to determine the regent and vice regents nominated for the local election. Candidate selection is the political domain of political parties, but in the context of figure-based politics, parties tend to play more as political vehicle in the candidacy of local head. Through this role, resource exchanges take place between parties and candidates within the internal party candidacy arena. Using qualitative methods through in-depth interviews and observations of candidate selection in the Bekasi Regent 2017 election, this article seeks to reveal how post-clientelist initiatives are used by party elites to optimize the incumbency advantage as main political resource in the candidate selection to determine who will pair the incumbent. The results show that the dominance of party elites in candidate selection process determines how financial resources and political support are optimized to win the incumbent. Decision to choose the vice-regent from the same party while still forming coalitions with other parties indicates that post-clientelistic strategy is operated both internally and externally. This practice confirms the tendency of the candidate selection model to be more inclusive because it involves other parties, but remains pragmatic.
INEVITABILITY OF REVIVAL: PRO AND COUNTER ANTINATALISM
Authors: Savkin Nikolay S.
Published: March 2019

Introduction. Radical pessimism and militant anti-natalism of Arthur Schopenhauer and David Benathar create an optimistic philosophy of life, according to which life is not meaningless. It is given by nature in a natural way, and a person lives, studies, works, makes a career, achieves results, grows, develops. Being an active subject of his own social relations, a person does not refuse to continue the race, no matter what difficulties, misfortunes and sufferings would be experienced. Benathar convinces that all life is continuous suffering, and existence is constant dying. Therefore, it is better not to be born. Materials and Methods. As the main theoretical and methodological direction of research, the dialectical materialist and integrative approaches are used, the realization of which, in conjunction with the synergetic technique, provides a certain result: is convinced that the idea of anti-natalism is inadequate, the idea of giving up life. A systematic approach and a comprehensive assessment of the studied processes provide for the disclosure of the contradictory nature of anti-natalism. Results of the study are presented in the form of conclusions that human life is naturally given by nature itself. Instincts, needs, interests embodied in a person, stimulate to active actions, and he lives. But even if we finish off with all of humanity by agreement, then over time, according to the laws of nature and according to evolutionary theory, man will inevitably, objectively, and naturally reappear. Discussion and Conclusion. The expected effect of the idea of inevitability of rebirth can be the formation of an optimistic orientation of a significant part of the youth, the idea of continuing life and building happiness, development. As a social being, man is universal, and the awareness of this universality allows one to understand one’s purpose – continuous versatile development.
AGRARIAN MOVEMENT IN SARANSK COUNTY IN OCTOBER-NOVEMBER 1917
Authors: Kistanov Sergey V.
Published: March 2019

Introduction. The study of the agrarian movement on the eve of the establishment of Soviet power in the regions of Russia is important in the light of determining the role of the peasantry in the process of coming into power of the Bolsheviks. It quite clearly demonstrates the polarization of social forces in the Russian village on the eve of the decisive events of the great Russian revolution in 1917, Therefore, the growth of the agrarian movement in the country during the period under review evidence of the crisis caused by the absence of a decision by the authorities of the agrarian question that occupies a prominent place in Russian social and political consciousness of the early twentieth century. Materials and Methods. The study uses the materials of the Central state archive of the Republic of Mordovia, as well as scientific literature. The main method of research used in the work is historical-genetic. A micro-historical approach is also used for a more detailed insight into the subject of the study. Results. The article deals with the direction of agricultural movement in the Saransk district through the prism of confrontation between the rich and poor parts of the village. It notes the main purpose of the agrarian-peasant movement: the landlords, the kulaks, the farmers. Forms of the agrarian movement directed against “the high society” of village are considered, and also the property damage caused to owners is stated. The study notes that the peasantry dissatisfied with the protracted solution of the agricultural issue by the Provisional government has moved to radical methods of “black redistribution”. The wealthy part of the village in these conditions was without protection from the district authorities which by the autumn in 1917 did not have any power or authority among the local population, which predetermined the success of peasant actions against “the high society”. Discussion and Conclusion. As a result of the conducted research the circle of victims in the period of “peasant revolt” in autumn 1917 in the territory of Saransk district of Penza province is revealed. Forms of influence in relation to each category of rural owners are defined. Also it notes the hopelessness of the situation of “the high society” of village against the background of the crisis of local authorities on the eve of the establishment of Soviet power.

Objective: To compare the width of the dental arches between overweight and non-overweight subjects . Materials and Methods: A cross-sectional comparative study was carried out with 54 subjects from 8 to 13 years of age, 27 normal-weight and 27 overweight. The presence of overweight was assessed according to the Quetelet index. To determine the width of the dental arches, measurements of the upper and lower intercanine and intermolar width were obtained with a digital calibrated Vernier caliper. The comparison between the dental arch width of normal-weight and overweight subjects was performed using the Mann-Whitney U test. Results: Statistically significant differences were found in the intercanine and intermolar widths between overweight and non-overweight subjects (p<0.05). Conclusion: The dental arches were wider in overweight subjects compared to those of normal-weight.

The Pterygospinous Ligament (PSL) extends from the Pterygospinous process of the lateral Pterygoid plate to the spine of the sphenoid bone. Sometimes, it may be ossified forming a bar of bone bounding the pterygospinous foramen to which mandibular nerve and its branches are variably related. Mandibular and chorda tympani nerves may get compressed depicting various clinical symptoms, which in turn depend upon dimensions of the foramen and grades of compression. Therefore, knowledge of the position and extent of ossification of PSL and its relation to the important structures in the deep infratemporal fossa is important for radiologists, neurologists, maxillofacial surgeons, dental surgeons and anesthesiologists during various anesthetic and surgical procedures.

Aim: To evaluate the association between malocclusion severity and psychosocial issues among Brazilian adolescents. Methods: The study sample consisted of 120 adolescents between 11 and 12 years, patients at the Dental School of the Federal University of Minas Gerais. Psychosocial issues were assessed by means of two questions, through which the adolescents were asked about whether a classmate had teased or called them names due to the condition of their teeth, or whether the adolescents had felt upset due to their teeth. The higher the response scores the greater the psychosocial impact. Malocclusion was evaluated with the Dental Aest-hetic. Index, with assignment of individuals to the following sub-groups: mild malocclusion (DAI≤25), moderate malocclusion (DAI=26–30), definite malocclusion (DAI=31–35) and severe malocclusion (DAI≥36). Results: Adolescents’ mean age was 11.50 years. The more severe the malocclusion the greater the frequency of episodes of teasing or name-calling because of the condition of the teeth (p=0.010), and the greater the frequency of episodes when the adolescents had felt upset due to their teeth (p=0.001). Individuals with severe malocclusion had a higher frequency of episodes during which they were teased or called names due to the condition of their teeth when compared to individuals with mild malocclusion (p=0.013). Individuals with severe malocclusion had a higher frequency of episodes in which they felt upset due to their teeth when compared to individuals with mild malocclusion (p<0.001), individuals with moderate malocclusion (p=0.002), and those with defined malocclusion (p=0.001). Conclusion: Severe malocclusion was associated with psychosocia

The aim of this study was to evaluate the relationship between some characteristics of primary dentition, and the frequency of parafunctional oral habits, with age and sex. Material and Methods: A cross-sectional study was carried out in a sample of 227 preschool children. Subjects’ parents or guardians were asked to sign an informed consent form. The epidemiological survey consisted of an oral examination and the application of a questionnaire (Cronbach's alpha=0.881), after calibration of a dentist (Kappa=0.932). To measure the reliability of the questionnaire, Cronbach's alpha was calculated, and for the associations, Mantel and Haenszel Square Chi-square test and likelihood ratio for contingency tables greater than 2x2 values were calculated. Results: Type 2 arch (72.7%), mouth breathing (26.0%) and onychophagia (17.2%) were the risk factors observed more frequently in the group under study. The type of arch was the only variable that was associated with sex (X2MH=4.443, p=0.035). Conclusion: A significant proportion of the subjects had at least one risk factor that may alter the development of dental occlusion; consequently, the implementation of preventive actions in this population must be considered

Objectives: To study the prevalence of methicillin resistant Staphylococcus aureus (MRSA) in saliva samples of pre-surgical oral squamous cell carcinoma (OSCC) patients along with their resistance pattern to other antibiotics. Methods: Saliva samples of OSCC patients were collected and processed for isolation of MRSA. Staphylococcus aureus isolates were primarily identified using standard microbiological methods like biochemical assays, specialized media and latex agglutination test. Confirmation of MRSA strains was done by growing the isolates on MRSA agar and by using PCR to amplify two MRSA specific genes. All the isolated Staphylococcus aureus strains were subjected to antibiotic sensitivity tests. Results: A total of 17 Staphylococcus aureus strains were isolated from 50 saliva samples of pre-surgical OSCC patients of which 13 were confirmed to be MRSA. These MRSA strains were also found to be mostly resistant to other commonly used antibiotics. Univariate analysis revealed that most patients with MRSA infections had a prior history of hospitalization and surgery. Also, it was confirmed that patients with other comorbidities and infections were more prone to having MRSA present in the saliva. Conclusion: The majority of Staphylococcus aureus isolates from the saliva of OSCC patients were MRSA, and were resistant to several other commonly used antibiotics.
