description: The Gamma-Ray Burst (GRB) 021211 detected by the High Energy Transient Explorer (HETE) II had a simple light-curve in the x-ray and gamma-ray energy bands containing one peak and little temporal fluctuation other than the expected Poisson variation. Such a burst offers the best chance for a unified understanding of the gamma-ray burst and afterglow emissions. We provide a detailed modeling of the observed radiation from GRB 021211 both during the burst and the afterglow phase. The consistency between early optical emission (prior to 11 minutes), which presumably comes from reverse shock heating of the ejecta, and late afterglow emission from forward shock (later than 11 minutes) requires the energy density in the magnetic field in the ejecta, expressed as fraction of the equipartition value or $ε_B$, to be larger than the forward shock at 11 minutes by a factor of about 10$^3$. We find that the only consistent model for the gamma-ray emission in GRB 021211 is the synchrotron radiation in the forward shock; to explain the peak flux during the GRB requires $ε_B$ in forward shock at deceleration to be larger than the value at 11 minutes by a factor of about 10$^2$. These results suggest that the magnetic field in the reverse shock and early forward shock is most likely frozen-in-field from the explosion, and therefore a large fraction of the energy in the explosion was initially stored in magnetic field. We can rule out the possibility that the ejecta from the burst for GRB 021211 contained more than 10 electron-positron pairs per proton.

description: TNO Applied Geosciences (1); TNO Advisory Group for Economic Affairs (2); TNO Geomodelling (3); TNO Geo Data and IT (4); TNO Monitoring and Control Services (5); TNO Data Science (6) Multiphase mass and heat transfer are ubiquitous in the subsurface within manifold applications. The presence of fractures magnifies the uncertainty of the heat transfer process, which will significantly impact the dynamic transport process. However, accurate modeling methodologies for thermal high-enthalpy multiphase flow within fractured reservoirs are quite limited. In this work, the geothermal multiphase flow in the high-resolution fractured reservoir is numerically investigated. The discrete-fracture model is utilized to describe the fractured system with discretization of optimized resolution. A synthetic fracture model is selected to run on different levels of discretization with different initial thermodynamic conditions. A set of comprehensive analysis is conducted to compare the convergence and computational efficiency of simulation results. The numerical scheme is implemented within the Delft Advanced Research Terra Simulator (DARTS), which can provide fast and robust simulation to energy applications in the subsurface. Based on the converged numerical solution, a thermal Peclet number is defined to characterize the interplay between thermal convection and conduction. Different heat transfer stages are recognized on the Peclet curve in conjunction with production regimes in synthetic fractured reservoir. Afterward, a realistic fracture network, sketched and scaled up from a digital map of a realistic outcrop, is utilized to perform sensitivity analysis on the key parameters influencing the heat and mass transfer. The thermal propagation and Peclet number are found to be sensitive to flow rate and thermal parameters. The findings provide insights for the multiphase mass and heat transport in the fractured high-enthalpy geothermal reservoirs, which can be taken as guidance for the practical geothermal developments with uncertainties.

description: This study measures levels of technical, allocative and economic efficiency in agricultural crop production for Brazil in 1995. A nonparametric frontier model (DEA) under constant returns to scale was used. On average, the results suggest that the sector suffers from moderate technical inefficiency and from strong allocative inefficiency. If full technical efficiency were achieved, the crop production would increase by more than 30% over that obtained in 1995. Land and labor were overutilized, while fertilizers and pesticides were underutilized. Climate, soil conditions and irrigation use affected technical efficiency levels, and education in rural areas helped explain the extent of allocative efficiency. The state of São Paulo State was the only production unit in Brazil operating in full efficiency in 1995.

description: In this paper, we use an economics decision-making experiment to test a key assumption underpinning the efficacy of price-level targeting relative to inflation targeting for business cycle stabilization and mitigating the effects of the zero lower bound on nominal interest rates. In particular, we attempt to infer whether experimental participants understand the stationary nature of the price level under price-level targeting by observing their inflation forecasting behaviour in a laboratory setting. This is an important assumption since, without it, price-level targeting can lead to worse outcomes than inflation targeting. Our main result suggests that participants formulate inflation expectations consistent with the target-reverting nature of the price level but that they do not fully utilize it in their forecasts of future inflation.
description: Les auteurs font une série d’expériences en laboratoire pour tester une hypothèse clé qui explique la supériorité que les cibles de niveau des prix affichent sur les cibles d’inflation en matière de stabilisation économique et d’atténuation des effets de la borne limitant les taux d’intérêt nominaux à zéro. Ils tentent en particulier d’établir si les participants à l’exercice reconnaissent la nature stationnaire du niveau des prix lorsque la cible est définie en fonction de ce dernier, et ce, en étudiant leur comportement prévisionnel en laboratoire. Cette hypothèse est cruciale, car si elle n’est pas respectée, le ciblage du niveau des prix peut donner de moins bons résultats que celui de l’inflation. La principale conclusion des auteurs est que les attentes d’inflation que formulent les participants cadrent avec la propension du niveau des prix à revenir à la cible, mais que leurs prévisions de l’inflation future n’intègrent pas entièrement cette information.

(Fig. 23, 45, 66)
 Heterocerus undatus Melsheimer 1844: 98.
 Dampfius undatus (Melsheimer): Pacheco 1964: 114.
 Description. Length 3.2 - 4.5 mm. Brown or reddish-brown. Elytra vaguely trifasciate, limits of pale markings poorly defined; striae absent (Fig. 23). Post-metathoracic coxal lines absent, post-mesothoracic coxal lines present. Male genitalia (Fig. 45) of the H. undatus type; about two times longer than wide; phallobase composed primarily of median plate; posterior two-thirds of median plate gradually expanded anteriorly; anterior third abruptly constricted to about 50% of its greatest width and pointed apically, curved dorsally in lateral view; lateral arms attached to the constricted portion of the median plate and curved outwardly at their anterior ends; anterior two-thirds of dorsal plate ovoid, posterior third with parallel sides; membranous parameres small, pointed and extending from beneath the median plate at its anterior tip; anterior end of median plate and parameres not extending beyond the anterior tip of the lateral arms. Hypermandibulate males unknown.
 Diagnosis. Although the general color in this species is often darker than it is in H. collaris, the two species are very similar in appearance and can be distinguished with certainty only by comparing male genitalia. The outwardly curved anterior tips of the lateral arms separate this species and H. collaris from other North American species. Heterocerus undatus is distinguished from H. collaris by the abrupt constriction of the median plate anteriorly, and by the median plate being much shorter (not exceeding the tip of the lateral arms) than that seen in H. collaris.
 Notes. One specimen of H. undatus is known from Mississippi. It was collected on the edge of a cultivated field near deciduous forest in Pontotoc County. A flooded ditch was the likely habitat.
 Distribution. Heterocerus undatus was previously recorded from the midwestern and northeastern United States into southeastern Canada, as far south as Missouri and Virginia (Miller 1996). Collection data indicates that H. undatus occurs west into southern Iowa and Kansas, and south into eastern Arkansas and northern Mississippi (Fig. 66).

description: Building on the growing evidence on the importance of large data sets for empirical macroeconomic modeling, we use a factor-augmented VAR (FAVAR) model with more than 260 series for 20 OECD countries to analyze how global developments affect the Canadian economy. We focus on several sources of shocks, including commodity prices, foreign economic activity, and foreign interest rates. We evaluate the impact of each shock on key Canadian macroeconomic variables to provide a comprehensive picture of the effect of international shocks on the Canadian economy. Our findings indicate that Canada is primarily exposed to shocks to foreign activity and to commodity prices. In contrast, the impact of shocks to global interest rates or global inflation is substantially lower. Our findings also expose the different channels through which higher commodity prices impact the Canadian economy: Canada benefits from higher commodity prices through a positive terms of trade shock, but at the same time, higher commodity prices tend to lower global economic activity, hurting demand for Canadian exports.
description: Sur la base des indications croissantes de l’importance des vastes ensembles de données en modélisation macroéconomique empirique, nous utilisons un modèle VAR enrichi de facteurs (modèle FAVAR) et plus de 260 séries relatives à 20 pays de l’OCDE pour analyser l’incidence de l’évolution mondiale sur l’économie canadienne. Nous nous intéressons tout particulièrement à certaines sources de chocs, notamment les prix des produits de base, l’activité économique à l’étranger et les taux d’intérêt étrangers. Nous évaluons les répercussions de chaque choc sur des variables macroéconomiques canadiennes clés afin de dresser un tableau complet de l’effet des chocs internationaux sur l’économie du pays. Nos résultats indiquent que le Canada est principalement exposé aux chocs touchant l’activité étrangère et les prix des produits de base. Par contre, il est beaucoup moins exposé aux chocs qui frappent les taux d’intérêt ou d’inflation mondiaux. Nos résultats mettent également au jour les divers canaux par lesquels les hausses de prix des produits de base se répercutent sur l’économie canadienne : ces hausses avantagent le pays par l’amélioration des termes de l’échange qu’elles entraînent, mais, parallèlement, elles ont tendance à ralentir l’activité économique mondiale, nuisant ainsi à la demande des exportations canadiennes.

description: Geological Survey of Slovenia (1); Geological Survey of Denmark and Greenland, Denmark (2)

The geographical coverage of the Minerals Inventory is being extended with data from the West Balkan countries as mineral data from this region represented a gap in the existing mineral inventory. Therefore mineral data from seven South East Europe countries (Serbia, Albania, Bosnia and Herzegovina, Croatia, North Macedonia and Montenegro) were obtained , evaluated and transformed into Inspire compliant common European mineral system with the support of GeoZS experts in the frame of EIT RM “RESEERVE” project. The process of refining the European Minerals Inventory, includes: (a) geographical coverage expansion, (b) setting up quality control application to identify data gaps, low-quality or missing data and data errors, (c) technical errors identification in the harvesting process and (d) establishment of links with other related projects. MINTELL4EU Quality Control Application (QCA) was developed to examine the latest data reported by data providers . Accordingly, a harvesting system for the collection and validation of mineral resources data has been established by the Geological Survey of Slovenia. Harvesting is a process that collects and validates data from different sources and automatically extracts data from numerous web services into a central database. Presently, the harvesting is performed once a month for 31 data providers across Europe. The process utilizes INSPIRE solutions as a common standard. Technical routines developed as part of the harvesting process allow online control of data quality and verify that the harvesting was successfull. The activities described above are implemented within GeoERA ERA-NET Co-Fund Action in Mintell4EU and GIP-P projects. GeoERA has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 731166.

 Peditatus texanus Pacheco 1964: 122.
 Description. Length 2.9 - 3.5 mm. Brown or reddish-brown. Elytra trifasciate, with two distinct basal spots (Fig. 24); surface relatively shiny; striae absent. Post-metathoracic coxal lines absent, post-mesothoracic coxal lines present. Male genitalia (Fig. 46) of the H. undatus type; slightly more than two times longer than its greatest width; body of phallobase dominated by median plate; anterior half of median plate gradually expanded anteriorly, anterior edge with a rounded central lobe and dorsal spinelike projections laterally; lateral arms of phallobase greatly reduced and projecting from notches between central lobe and lateral projections on the anterior edge of the median plate; dorsal plate with a bilobed projection on its anterior edge that extends beyond the parameres; parameres membranous, small, bilobed and extending from beneath the rounded central lobe of the median plate. Hypermandibulate males unknown.
 Diagnosis. This species is most similar to H. schwarzi and H. tenuis, two less common southeastern species. The elytral surface of H. texanus is smoother and has wider pale yellow markings in comparison to the other two species. Male genitalia should, however, be used to separate the three, unless a side-byside comparison with identified material is possible. Heterocerus texanus lacks the long dorsally curved spines seen on the lateral projections of the median plate that are present in H. schwarzi and H. tenuis (compare Fig. 46 and 47). The latter two species also have a conspicuous plate on the ventral side of the anterior tip of the genitalia.
 Notes. Heterocerus texanus is relatively common throughout Mississippi and Alabama. In the study area, this species is commonly collected from the banks of the Mississippi River and nearby oxbow lakes. It has also been collected from coastal areas, and occasionally from ponds, swamps and small streams. On two notable occasions, specimens were collected in relatively large numbers from the banks of the Mississippi River, along with large series of H. pallidus. Molecular data suggests that these two species are close relatives, although their general morphology would suggest otherwise.
 Distribution. Heterocerus texanus occurs from southern Texas north to Iowa and east to the coast of the Carolinas and south to Florida (Fig. 67).

Publisher: name: Challenging Glass Conference Proceedings
Year: 2018

description: Laboratory testing data concerning the full sized laminated glass panel with different glass make-ups under impact is limited. An experimental investigation on the impact resistance of LG panels under hard body impact is reported in this paper. A test approach namely, mean minimum breakage velocity approach, is adopted to capture the minimum impact energy that triggers each glass breakage. The crack morphology of glass panels is firstly investigated. Results indicate that the intersection angle of the radial crack edges increases when the strengthening level of glass decreases. The impact resistance is then revealed by investigating the effects caused by three design variables, i.e., the glass types, interlayer thickness and interlayer types. It reveals that the configuration with inner HS glass and outer FT glass panel can provide better impact resistance, and performs better in keeping initial stiffness under repeated impacts with higher impact velocity. In the contrast, placing HS glass in the both side may weaken the impact resistance. A 1.52 mm PVB interlayer can provide better impact resistance and higher initial stiffness when compared to a thicker interlayer, it is more likely to produce stiffness degradation between consecutive breakages as well. The difference of SGP LG and PVB LG in MMBV is found to be negligible, however, SGP LG exhibits evidently higher initial pre breakage stiffness and remains greater post breakage strength.

description: We present the Star cluster Hunting Pipeline (SHiP) which can identify star clusters in GAIA DR2 data, and establish a star cluster catalog for the Galactic disk. A Friend of Friend based cluster finder method is used to identify star clusters using 5-dimensional stellar parameters, $l, b, \varpi, μ_α\cosδ$, and $μ_δ$. Our new catalog contains 2443 star cluster candidates identified from disk stars located within $|b|=25^\circ$ and with $G<18$ mag. An automatic isochrone fitting scheme is applied to all cluster candidates. With a combination of parameters obtained from isochrone fitting, we classify cluster candidates into three classes (Class 1, 2 and 3). Class 1 clusters are the most probable star cluster candidates with the most stringent criteria. Most of these clusters are nearby (within 4 kpc). Our catalog is cross-matched with three Galactic star cluster catalogs, Kharchenko et al. (2013), Cantat-Gaudin et al. (2018, 2019), and Bica et al. (2019). The proper motion and parallax of matched star clusters are in good agreement with these earlier catalogs. We discover 76 new star cluster candidates that are not listed in these 3 catalogs. The majority of these are clusters older than log(age/yr)=8.0, and are located in the inner disk with $|b|<5^\circ$. The recent discovery of new star clusters suggests that current Galactic star cluster catalogs are still incomplete. Among the Class 1 cluster candidates, we find 56 candidates for star cluster groups. The pipeline, the catalog and the member list containing all candidates star clusters and star cluster groups have been made publicly available.

description: Preference Shifts, Structural Breaks and the Domestic Demand for Chilean Wine Cristián Troncoso-Valverde1 Abstract – This paper investigates possible changes in Chilean domestic consumer preferences for wine through the estimation of a demand function that allows for structural breaks and regime shifts in the cointegrating relationship. Our findings support both higher own–price elasticity and higher substitutability between wine and beer after 1982, when a shift in regime in the demand function is found. We believe our findings might be due to the introduction of an increasing number of wine varieties in Chile during the last two decades. We argue that more wine varieties affect domestic consumer preferences by altering the product diversity available in the domestic market.

description: In this work, by using multi-scale characterizations from electron channeling contrast imaging (ECCI) to atom probe tomography (APT), we directly evidenced that the massive cracking events in the selective-laser-melted (SLMed) Haynes 230 superalloy are due to the continuous decoration of an M23C6-type thin film at grain boundaries. The high-melting-point nature of the carbide rules out the possibility of liquidation cracking, while the long and straight film surface facilitates stress-induced solid-state cracking. Impurities, Si, Mn and Fe, greatly enhance the cracking susceptibility despite the interesting fact that they are strongly depleted from the carbide. The massive cracking events in the selective-laser-melted Haynes 230 superalloy are due to the continuous decoration of an M23C6 film at grain boundaries, regardless of the detailed cracking modes.
Volatility in the international food markets: implications for global agricultural supply and for market and price policy

description: Agricultural countries usually produce multiple crops, but a particular area of land is allocated to the production of a certain crop. Understanding how producers make decision to allot acreage among crops and how decisions about land use are affected by changes in prices and their volatility is fundamental for both policy design and for estimation models of the behavior of agricultural producers. The profitability of a land allocated to a certain crop is affected by the volatility of the crop’s price that in turn affects the acreage allocation decision of the producer. To address this, the present paper estimates global acreage response equations for major agricultural commodities (wheat, maize, soybeans and rice) using two related databases: globally aggregated time series and cross-country panel databases. The paper addresses the debate of agricultural market regulation from the perspective of agricultural producers. The findings of this study reveal that, while higher output prices are incentives to improvements in the global crop supply, output price volatility, on the other hand, discourages agricultural investment in terms of cropland expansion. Depending on respective crop, short-run acreage elasticities range between 0.05 and 0.25 whereas price volatility tends to reduce acreage response of all crops except of soybeans. Thus, price volatility management tools, which could include market regulation but also other market based tools like futures contracts or contract farming, need to be customized to specific crops and countries.
title: A Stochastic Volatility Model with Conditional Skewness

Year: 2011

description: We develop a discrete-time affine stochastic volatility model with time-varying conditional skewness (SVS).   Importantly, we disentangle the dynamics of conditional volatility and conditional skewness in a coherent way. Our approach allows current asset returns to be asymmetric conditional on current factors and past information, what we term contemporaneous asymmetry. Conditional skewness is an explicit combination of the conditional leverage effect and contemporaneous asymmetry. We derive analytical formulas for various return moments that are used for generalized method of moments estimation. Applying our approach to S&P500 index daily returns and option data, we show that one- and two-factor SVS models provide a better fit for both the historical and the risk-neutral distribution of returns, compared to existing affine generalized autoregressive conditional heteroskedasticity (GARCH) models. Our results are not due to an overparameterization of the model: the one-factor SVS models have the same number of parameters as their one-factor GARCH competitors.
description: Les auteurs élaborent un modèle discret affine à volatilité stochastique et asymétrie conditionnelle variable (modèle SVS). Leur approche a ceci d’intéressant qu’elle dissocie de façon cohérente la dynamique de la volatilité conditionnelle de celle de l’asymétrie conditionnelle. Elle permet une distribution asymétrique des rendements courants des actifs conditionnellement aux facteurs du moment et à l’information passée, asymétrie que les auteurs qualifient de « contemporaine ». Dans leur modèle, l’asymétrie conditionnelle découle de la combinaison explicite de l’effet de levier conditionnel et de l’asymétrie contemporaine. Les auteurs établissent les formules analytiques pour divers moments des rendements utiles pour l’estimation par la méthode des moments généralisés. En se servant de données relatives aux rendements journaliers de l’indice S&P 500 et aux options connexes, ils montrent que les modèles SVS à un et à deux facteurs décrivent mieux la distribution des rendements (tant historique que risque neutre) que les modèles GARCH affines existants. Leurs résultats ne tiennent pas à un surparamétrage, puisque les modèles SVS unifactoriels comptent le même nombre de paramètres que les modèles GARCH unifactoriels.

description: Kosovo, like most of rural Central and Eastern Europe, has witnessed substantial out-migration in recent years, prompting debates on the effect of migration on agricultural efficiency. This paper addresses this issue, drawing on a large (n=2217) and representative sample of agricultural households. A two-stage estimation procedure is followed: a frontier technique to estimate the effect of migration on farm efficiency, followed by a matching estimation approach to robustly estimate the sample average effect on efficiency for different levels of migration intensity. Migration has an efficiency decreasing effect which is amplified for better educated and older workers.

description: TNO - Geological Survey of the Netherlands, The Netherlands

A large, densely populated part of the Netherlands is located below mean sea level. The risk of flooding is therefore omnipresent. Dikes are vital for safety, and local waterboards apply high standards when monitoring and maintaining the dikes. The waterboard ‘Hoogheemraadschap de Stichtse Rijnlanden’ (HDSR) has launched a maintenance program to investigate and reinforce the 55km long northern Lek River dike between Schoonhoven and Amerongen. As the dike’s strength depends on both its design and its subsurface, detailed knowledge of the local geology is essential. Along the Lek, the subsurface is characterized by a heterogeneous composition of the shallow subsurface and HDSR requires a higher level of detail than provided by the currently available 3D voxel model GeoTOP (Stafleu et al., 2012. TNO 2012 R10991). We constructed a 3D geological model, based on the GeoTOP workflow, for three sub-trajectories beneath the dike with a voxel size of 25x25x0.25m. The lithology of each voxel is modelled based on borehole descriptions, cone penetration tests (CPT) and paleogeographic maps. Applying machine-learning to retrieve lithological data from CPT’s increased the data density and allowed for high-resolution modelling. The new high-resolution model is now used by the waterboard to: - identify dike-trajectories that need further investigation - design location-specific and fit-for-purpose dike reinforcement measures - explain proposed measures to local stakeholders. The first two applications potentially reduce costs significantly; whereas the third application aids creating social foundation for reinforcement measures. Most importantly, the new high resolution model helps HDSR to enhance safety behind the dikes.

description: This paper constructs a theory of the coexistence of fixed-term and permanent employment contracts in an environment with ex-ante identical workers and employers.  Workers under fixed-term contracts can be dismissed at no cost while permanent employees enjoy labor protection. In a labor market characterized by search and matching frictions, firms find it optimal to discriminate by offering some workers a fixedterm contract while offering other workers a permanent contract. Match-specific quality between a worker and a firm determines the type of contract offered. We analytically characterize the firm’s hiring and firing rules. Using matched employer-employee data from Canada, we estimate the model’s parameters. Increasing the level of firing costs increases wage inequality and decreases the unemployment rate. The increase in inequality results from a larger fraction of temporary workers and not from an increase in the wage premium earned by permanent workers.
description: Les auteurs élaborent un cadre théorique pour expliquer la coexistence de contrats à durée déterminée et de contrats de travail permanents dans un milieu où travailleurs et employeurs sont a priori identiques. Les travailleurs temporaires sont licenciables sans frais, alors que les employés permanents jouissent d’une protection d’emploi. Sur un marché du travail caractérisé par des frictions dans la prospection et l’appariement, les entreprises jugent optimal d’opérer des distinctions en proposant à certains travailleurs un contrat à durée déterminée et à d’autres un contrat permanent. La qualité intrinsèque de l’appariement entre le travailleur et l’entreprise motive le choix du contrat offert. Les auteurs définissent par analyse les règles d’embauche et de congédiement des entreprises.  Les paramètres du modèle sont estimés à l’aide de données canadiennes relatives au jumelage employeurs-salariés. La hausse des coûts de licenciement accroît l’inégalité des salaires et réduit le chômage. Cette montée de l’inégalité est causée par la présence d’une plus grande proportion de travailleurs temporaires et non par la majoration du surplus de rémunération octroyé aux travailleurs permanents.

description: Laminated glass fulfills the demands on safety and security in transparent structural elements used in architecture and other fields of engineering. It can be constructed as forced-entry, bullet, or blast resistant. The basic three-layer configuration consists of two glass panes connected with a polymer or ionomer interlayer; the advanced products contain also other layers. The foil ensures shear coupling and provides post-breakage resistance and damping. For the design of laminated glass structures and their analysis, knowledge of mechanical properties of interlayers is essential. In numerical simulations, the interlayer is most typically described by the generalized Maxwell chain ‒ a classical viscoelastic model which can capture the time/temperature-dependent response of polymers under shear. Its parameters can be found for common interlayer types in the literature. However, they differ even for the same material, because of a slightly different content of additives, different test setups, and different data processing procedures. In this contribution, the dependence of the response of a laminated glass element on the material parameters of the polymer interlayer is studied by means of numerical modelling and experiments. Two examples are shown and discussed, i.e., quasi-static analysis of a simply-supported beam and modal analysis of a free-free beam. Numerical predictions are obtained by a layer-wise model based on the finite element method. These predictions are validated against the detailed experimental data. We demonstrate that using the Maxwell model parameters from the literature determined even for the same material type but not for the concrete foil may lead to unrealistic predictions.

description: We have studied the dynamic effect of nonlinearity on lasing in disordered medium. The third-order nonlinearity not only changes the frequency and size of lasing modes, but also modifies the laser emission intensity and laser pulse width. When the nonlinear response time is comparable to or longer than the lifetime of the lasing mode, the nonlinearity changes the laser output through modifying the size of the lasing mode. When the nonlinear response is much faster than the buildup of the lasing mode, positive nonlinearity always extracts more laser emission from the random medium due to the enhancement of single particle scattering.

description: Looking at a current architecture, there are many examples of glass load bearing structures such as beams, panes, balustrades, columns or even stairs. These elements are mostly made of laminated glass panels. Panels are bonded together with polymer interlayer significantly influencing a shear forces transfer between them. There is still overall lack of knowledge in the task of shear forces transfer between these panels. It principally depends on the polymer stiffness, which is affected by an ambient temperature, humidity and load duration. Civil engineers currently tend to design laminated glass members on the safe side, generally not taking laminated panels interaction provided by the interlayer into account. This approach leads to uneconomical and robust glass bearing members significantly preventing the use of laminated glass more extensively. There are many polymer interlayers made for structural laminated glass applications available on a market. Most of them differ in stiffness and other important properties therefore these must be experimentally examined to design safer and more economical laminated glass members. This paper is focused on the shear modulus of PVB (polyvinyl-buthyral) and SentryGlasÒ (ionoplast) experimental investigations as a function of temperature and loading ratio. It is possible to find out these functions by static creep or relaxation tests as well as by dynamic mechanical thermal analysis-DMTA. A lot of DMTA experiments in shear with the aforementioned interlayers in various loading conditions have been performed in order to determine their shear stiffness. It also enables to identify their Prony parameters as a part of the next survey. Experimentally verified common polymer interlayer stiffness helps engineers to design safer and cheaper glass constructions. This is the way how to extend the use of laminated glass in a current architecture.
