Published: September 2019

Abstract
Objective Previous studies have indicated that dentists may be uncertain about the etiology, diagnosis, and effective management of dentine sensitivity/dentine hypersensitivity (DH). The purpose of the present study was to evaluate the knowledge and understanding of Greece-based dental professionals in treating DH.

Materials and Methods A 26-item questionnaire was sent to a representative sample of Greek dentists.
Results Two hundred thirty questionnaires were originally provided to the participants and of the 210 questionnaires that were returned, 191 questionnaires (90 M; 86 F; mean age 36.26 years [standard deviation: 11.34]) were included for analysis, a response rate of 83% was observed. 39.8% of dentists indicated that 1 in 10 of their patients experienced discomfort from DH with 76.4% of dentists indicating that their patients initiated the conversation on DH. In contrast, 44% of the dentists indicated that they initiated the relevant conversation. 34.9% of dentists indicated that the duration of discomfort lasted up to 3 weeks and 76.4% indicated that DH had an impact on their patients’ quality of life. Incorrect tooth brushing was considered to be a major etiological factor (68.6%) with “air blast” (37.3%) and “probing” (15%) as the main methods for identification. 83.6% of dentists indicated that they were confident in recommending over-the-counter products for home use.
Conclusion The results of this study suggest that in terms of knowledge and understanding of DH, there is still confusion concerning some aspects of the diagnosis and management of the condition.

Published: September 2019

ABSTRACTObjectives: The majority of the pathologic structures which are seen in the oral and maxillofacial region are either cystic or tend to show cystic changes. They may have not specific clinical and radiographic findings. Therefore, it is difficult to differentiate these lesions preoperatively. For this purpose, in this research, the value of fine-needle aspiration cytology (FNAC) in preoperative diagnosis was investigated by comparing with the postoperative histopathologic diagnosis.Methods: One hundred aspirates from cystic lesions in the oral and maxillofacial region were included in this study. All of the samples except one were examined histopathologically and the results were compared.Results: The results of the FNAC specimens obtained from 100 lesions were compared with histopathologic diagnosis of these lesions. According to these results, 12 insufficient (12%), 7 positive (7%), 81 negative (81%) specimens were obtained. Among these 88 lesions, 69 of them were diagnosed specifically by cytological examination (78.4%). 62 of the 69 specific diagnoses achieved by cytological examination were confirmed histopathologically (89.85%). The histological types of the seven lesions were missed by cytological examination. There were not any complications related with the fineneedle aspiration procedure in the research.Conclusions: According to these results, the value of fine-needle aspiration biopsy in cystic lesions of the maxillofacial region is found as successful as in the solid lesions.

Abstract
A series of specialised acousto-optic modulators/frequency shifters based on paratellurite (TeO2) single crystals is developed for systems of laser cooling and frequency stabilisation of laser sources in optical and microwave frequency standards based on cold strontium, rubidium and caesium atoms. The methods of calculation and optimisation of the main parameters of acousto-optic modulators are considered; their basic technical characteristics are experimentally investigated in the spectral range of optical radiation 460 – 900 nm and in the frequency shift range of 5 – 400 MHz. The modulators have a high diffraction efficiency, low power consumption and the ability to work with linearly and randomly polarised optical radiation.
Geological structure and conditions of formation of Strizhkovskoe barite-polymetallic deposit (Ore Altai)
Authors: Bestemianova K V , Grinev O M 
Published: September 2019

Abstract
Strizhkovskoe barite-polymetallic deposit is a typical medium-low-temperature hydrothermal-metasomatic deposit.
It’s located within north-west part of Zmeinogorsk-Bystrushinskiy downfold; host rocks are volcano-terrigenous Devonian rocks. Ore bodies are related to sublatitudinal and submeridional faults intercrossing.
Wallrock quartz-chlorite-sericite metasomatites formed prior to ores formation. Ore mineralization process began in Middle Devonian. Main ore minerals are sphalerite, galena, and chalcopyrite. Also there are gold and silver occurring as electrum, acanthite; silver is present in fahlores as an isomorphous admixture. Formation of the deposit subdivides into two main stages and five phases; according to obtained results of isotope study of the sulfides, it’s possible to conclude that there was a mixed source of ore matter (mantle source replacing with crust source). The temperature of main ore formation stage varied form 230 to 180 degrees. Solutions salinity varied from 9 to 15 % wt of NaCl equiv. According to fluid inclusions study results, the solutions consisted of water and following compounds CO2, NH3, SO2, HCO3.

Published: September 2019

Abstract
Zircon and monazite ID-TIMS U-Pb dating of four Lower Ordovician altered ash-fall tuff beds (K-Bentonites) in NW Iberia provided coetaneous ages of 477.5±1, 477±1.3 Ma, 477.2±1.1 Ma and 477.3±1 Ma, with a pooled concordia age of 477.2±0.74 Ma. A conservative estimation of the volume and mass of the studied K-bentonite beds (using data from the Cantabrian Zone) returns a minimum volume for the preserved deposits of ca. 37.5 km3 (Volcanic Explosivity Index - VEI = 6, Colossal). When considering other putative equivalent beds in other parts of Iberia and neighbouring realms the volume of ejecta associated to this event would make it reach the Supervolcanic-Apocalyptic status (VEI=8, >1000 km3). Contrary to most cases of this kind of gargantuan eruption events, the studied magmatic event took place in relation to continental margin extension and thinning and not to plate convergence. We speculate that a geochronologically coincident large caldera event observed in the geological record of NW Iberia could be ground zero of this super-eruption.
Contrasting metamorphic gradients: Barrovian-type vs. high-pressure metamorphism. An example on the northern margin of Gondwana (NW Iberia)

Published: September 2019

Abstract
Contrasting metamorphism in adjacent terranes is distinctive of large-scale tectonic events that include both collisional and rifting scenarios. When one of those terranes is characterized by the presence of high-pressure rocks, it is more likely to be related to collisional settings, and commonly in locations close to the suture. This contribution shows an example of the aforementioned situation in the Variscan orogenic belt of NW Iberia, where a tectonic slice with high-pressure metamorphism is above rocks that underwent Barrovian metamorphism. The two involved terranes are known as lower allochthon and parautochthon, respectively. The lower allochthon recorded the continental subduction (blueschist- and eclogite-facies conditions; [1,2]) of the most external part of the north Gondwana passive margin during the late Devonian (ca. 370-365 Ma; [1, 3]) at the beginning of the Variscan collision, followed by a buoyancy-driven exhumation triggered by the extensional collapse of the orogenic pile. Contrarily, the underlying parautochthon underwent crustal thickening, resulting in a medium-pressure Barrovian-type metamorphism that possibly was followed by a higher temperature/lower pressure Buchan-type metamorphism that may be related to tectonic exhumation and/or erosion [cf. 4].
Chemical composition and varieties of sulfosalts from gold mineralization in the Gaching ore occurrence (Maletoyvayam ore field)
Authors: Shapovalova M , Tolstykh N , Bobrova O 
Published: September 2019

Abstract
The Gaching ore occurrence within the Maletoyvayam ore field is located in the southwestern part of Kamchatka volcanic belt. The ore occurrence belongs to high-sulfidation epithermal type. The sulfosalts of the fahlore-group (tennantite, tetrahedrites and goldfieldite) and enargite-groups (enargite, luzonite, famatinite) found in the gold mineralization of the Gaching ore occurrence. The presence of Cu-rich and Se-bearing fahlores as well as enargite-group sulfosalts in ores indicate a high oxygen volatility at temperature less than 250º during their formation.

Abstract
Sustainable landscape consist of the healthy provision of ecological services and the improvement of local human well-being. However, habitat transformation often affects pollinators. There is still a lack of research about how far does pollinators presence is being changed by habitat types. The aim of this research is to investigate the consequence of habitat transformation to pollinator diversity among habitat types. This research was conducted in the Harapan Forest, Jambi on three types of habitat from April to September 2017. Pollinators were collected using insect net and traps in and around the flowering plants in the plots. All pollinators were brought to the laboratory for identification. The highest abundance and species richness of pollinators were found in rubber and oil palm plantation, while the lowest were found in secondary forest. These results seem to be related to the presence of flowering plants that were more abundant in rubber and oil palm plantation compared to secondary forest. Different species of pollinators has different responses to the habitat transformation. For instance, the genus Tetragonula spp. (Hymenoptera: Apidae) were found to be highly abundant in secondary forest, whereas Ceratina spp. (Hymenoptera: Apidae) were highly abundant in rubber and oil palm plantation.

The development of land-use in the upper Ciliwung watershed can be converted every year, which has an impact on surface flow, peak discharge and runoff volume. This study aims to look at projections of changes in land-use and their impact on changes in peak discharge and volume of river flows in the Ciliwung Hulu watershed. The tool used in this study consisted of a tool for analyzing land-use changes and projections, namely the CLUE-S model, while for hydrological responses using the HEC-GeoHMS tool combined with a GIS tool. The results of the analysis of land-use change found a pattern of changes in land-use in the Upper Ciliwung watershed in the period 1996-2013 there were 5 patterns of changes in land-use. Projected land-use change in 2030 with two scenarios. Scenario 2 which is able to hold the rate of change of forest to more than 30%. Scenario 1 HEC-HMS produces peak discharge 114.1 m3/second and runoff volume reaches 5.85 x 106m3 while in scenario 2 with peak discharge 107.0 m3/second and runoff volume 5.70 x 106m3.
The socio-economic impact of national and foreign oil mining companies existences and activities in Tjepu 1967-2004
Authors: Setiawan A 
Published: September 2019

Abstract
The aim of this paper is to analyze programs and policies run by national and foreign oil companies that affect the level of the economy of the people in Tjepu. While historical research usually focuses on events that are presented in chronological order, this study will add to the study of linkages between historical agencies/actors and the environment relating to the quality of the economy from generation to generation in the exploration and exploitation of national and foreign oil companies in Tjepu. This study uses historical methods, especially in collecting literature and field data including interviewing a number of people related to oil mining activities. The results of this study indicate that there are positive and negative sides of the existence of national and foreign oil companies operating in Tjepu. The existence of oil companies is opening up employment opportunities for local residents although the number is limited. In addition, the existence of oil companies also encourages the emergence of small businesses such as restaurants and other service businesses. But on the other hand, pollution due to mining activities also affects the health level of the community and pollutes the ground water in Tjepu
Fractured Domesticity in the Old Regime: Families and Global Goods in Eighteenth-Century France
Authors: Hardwick Julie 
Published: September 2019

Abstract
The fractured nature of emergent domesticity in its first phase in the 1760s was inextricably tied to the perils as well as promises of commerce for individual households in an unpredictable global economy, although historians have focused on the metropolitan roots of domesticity. A microhistorical exploration of the world of a single household in the French city of Lyon brings the fault lines of a globalizing economy, consumption, and domesticity into sharp focus as lived experience. It suggests the uneven terrain of domesticity, in terms of gender, household, and family, as well as for producers and consumers. In the experiences of household members and in the classified advertisements in the local newspaper, fractured domesticity was manifest, the conjugal labor—reproductive and productive—that made global domesticity local was evident, and the centrality of commercial risk as a fault line in domesticity was clarified. The power and limits of “domesticity” as an emotional, cultural, and economic as well as political project were located in familial practice. The potency and limits of domesticity functioned as a system of power that was contingent, layered, and fragmented and that highlighted and elided emotional, reproductive, and productive costs in particular ways at particular times.
Claw asymmetry in crabs: approaching an old issue from a new point of view

Published: September 2019

AbstractCrabs are considered exceptional examples of antisymmetry resulting from the phenomenon of heterochely. Here we investigate morphometrically both the size and the shape of heterochely in 28 crab species, distributed unequally along a brachyuran phylogeny. We address the importance of investigating claw size and shape for interspecific comparisons by linking geometric morphometric outputs to phylogenetic data for 134 brachyuran species. New indices introduced as new sexual dimorphic characters of size and shape, namely heterometry (right chela size/left chela size) and heteromorphy (Procrustes distance between right and left chelae shape), revealed sexually dimorphic differences in diverse crab species. We demonstrate that both size and shape heterochely occur amongst the examined species, but there are no ecological correlations. Our study demonstrates that claw similarity between two or more species was due mainly to phylogenetic relatedness rather than ecological convergence, suggesting that claw morphological features could be useful morphological markers in phylogenetic studies. Although further investigation is needed, this study represents one of the first to thoroughly analyse the origin and evolution of heterochely within the Brachyura clade.
Using a multi-isotope approach to understand waterfowl movement in southern Africa
Authors: Mutumi Gregory L , Cumming Graeme S , Sullivan S Mažeika P , Caron Alexandre , Cáceres Carlos 
Published: September 2019

AbstractMany far-ranging species depend heavily on relatively small or temporary resources within a heterogeneous landscape. For waterfowl, most species rely on deep, permanent waterbodies as refugia from predators during annual flightless molt periods when synchronous loss and regrowth of the flight feathers occurs. The movements of ducks to and from molt sites are, however, poorly documented for most Afrotropical species and the dependencies of Afrotropical ducks on key sites are unclear, yet this information is integral to conservation and management efforts. We asked whether stable isotopes of wing feathers could be used to determine the molting origins of Afrotropical ducks in southern Africa. We analyzed isotope ratios of carbon, nitrogen, oxygen, and hydrogen in feathers from 4 different species across 5 different sites (wetlands, ponds, lakes) in South Africa, Zimbabwe, Mozambique, and Botswana. We observed differences among sites for all isotopes (P &lt; 0.05), especially δ 13C and δ 15N. Based on these differences, we conducted linear discriminant function analysis (LDA) to assess the utility of these isotopes to assign birds to molt locations. We obtained a global classification accuracy = 0.59, although accuracies differed among sites. Our results demonstrate the potential of a multi-isotope approach to discriminate among specific molt locations and to provide an initial estimate of molt site. Rigorous documentation of molt site from wing feathers is plausible, but will require large sample sizes, extensive spatial coverage, and careful calibration.
Anti-predator behavior along elevational and latitudinal gradients in dark-eyed juncos
Authors: Andrade Madelin , Blumstein Daniel T 
Published: September 2019

AbstractFlight-initiation distance (FID), the distance between an individual and experimenter when it begins to flee, can be used to quantify risk-assessment. Among other factors, prior studies have shown that latitude explains significant variation in avian FID: at lower latitudes, individuals and species have longer FIDs than those living at higher latitudes. No prior studies have focused on the effect of elevation on FID. Given the similar patterns of seasonality, climate, and potentially predator density, that covary between latitude and elevation, birds at higher elevations might tolerate closer approaches. We asked whether elevation or latitude would explain more variation in the FID of a common passerine bird species, dark-eyed juncos (Junco hyemalis). Juncos live in a variety of habitats along both latitudinal and elevational gradients. We found that statistical models containing elevation as a variable explained more of the variation in FID than did models containing latitude. We also found, unexpectedly, that birds at higher elevation fled at greater distances. While more predators were sighted per hour at higher elevations than at lower elevations, the frequency of predator sightings did not explain a significant amount of variation in FID. This result questions whether predator density is the main driver of risk perception along elevational gradients. Nonetheless, because elevation explains more variation in FID than latitude in at least one species, these findings have direct implications on how human impacts on birds are managed. Specifically, those designing set-back zones to reduce human impact on birds may consider modifying them based on both latitude and elevation.
Perioperative management in a patient with panhypopituitarism – evidence based approach: a case report
Authors: Raut Monish S , Kar Sibashankar , Maheshwari Arun , Shivnani Ganesh , Dubey Sumir 
Published: September 2019

Abstract

Background
Hypopituitarism is characterized by partial or complete deficiency of vital endocrinological hormones such as steroid and thyroid hormones. Generally, normal individual can exhibit 2- to 10-folds rise in serum cortisol levels during stressful period. But patients with panhypopituitarism are more prone to develop metabolic and haemodynamic instability particularly during stressful perioperative period. This can potentially increase significant morbidity and mortality.

Case summary
A 62-year-old female patient presented with breathlessness on exertion. Her coronary angiography revealed critical triple vessel coronary artery disease, and she was scheduled for coronary artery bypass grafting surgery. She had been diagnosed with Sheehan’s syndrome (postpartum hypopituitarism) since 20 years. She was taking steroid and thyroxine regularly. After uneventful off-pump coronary artery bypass grafting surgery, patient had severe haemodynamic compromise with Addisonian crisis in the post-operative phase. Left ventricular dysfunction was refractory to maximal inotropic therapy. Addisonian crisis was treated with higher ‘Stress doses’ of intravenous hydrocortisone and routine oral thyroxin.

Discussion
Acute Addisonian crisis after stressful surgery is a life-threatening complication. Evidence-based approach plays an important role in appropriate biochemical assessments and specific therapeutic decisions regarding hormonal over-replacement or under-replacement in the perioperative period.
Gender differences in treatment with antidepressants during first weeks of a sick-leave spell due to depressive episode
Authors: Lytsy Per , Alexanderson Kristina , Friberg Emilie 
Published: September 2019

Abstract

Background
The incidence of depression is higher in women; women are more often on sick leave due to depression, and more women than men use antidepressants. The objective of this study was to explore possible gender differences in buying prescribed antidepressants during the first 21 days of a new sick-leave spell due to depressive episode.

Methods
Included were all individuals living in Sweden in working age (18–64 years old) who in 2010 or 2011 began a new sick-leave spell due to depressive episode (ICD-10 F32) lasting at least 21 days (n = 44 863). Register data on sociodemographics, morbidity and dispensed prescription medication were used to investigate associations between gender and buying prescribed antidepressants in the total group and in subgroups, using multiple logistic regression models.

Results
The study population consisted of 69.5% women. Within the first 21 days of the sick-leave spell, 48.0% of the men and 42.1% of the women had dispensed prescribed antidepressants. In the adjusted multiple logistic regression model, men had an odds ratio of 1.28 (95% confidence interval 1.23–1.33) as compared with women, for buying prescribed antidepressants.

Conclusions
In this nationwide register study, nearly half of the women and men on sick leave with depressive episode bought prescribed antidepressants during the first three weeks of the sick-leave spell. In the adjusted models, men were more likely to do this. Further studies are needed to elucidate the reasons for this gender difference.
