La crue du 18 mai 1994 au Trou qui Souffle (Vercors, France)
Authors: Lismonde Baudouin
Published: November 2018

Le 18 mai 1994, dans le Vercors septentrional, une pluie exceptionnelle sur un reste de manteau neigeux a provoqué une mise en charge de toute la partie inférieure du Trou qui Souffle (Méaudre). La montée des eaux a été de 100 m environ ; elle a noyé 14 km des 40 km topographiés dans ce réseau, le plus long du massif. Le volume noyé dans les parties connues était de l'ordre de 300 000 m3.
Signification des remplissages des karsts de montagne. Quelques clés à l'usage des spéléologues
Authors: Audra Philippe
Published: November 2018

Signification of mountain karst infillings. This paper is intended to cavers in order to help them identify the most significant mountain karst infillings. Carbonated varves sedimentation occurs during floodings in glacial environment. The varves block the deep parts of the networks. Pebbles sealings show a powerful erosion in the vadose zone, near glacial sinkholes. Gelifract spreadings are indicators of frost and snow action in periglacial environment. Reworked weathered rocks are the most ancient deposits, inherited from tertiary warm phases when karsti-fication occurred under regolith covers. Their clearing is partly simultaneous with cave systems elaboration, in relation to the alpine uplift, during Pliocene. Speleothems are also warm or temperate climate indicators. Crystalline morphology reflects environmental characteristics, while their surface sight could have been smoothed during discharge reactivations. Finally, some infillings could have recorded neotectonic movements : broken speleothems, deformed clastic sediments, etc.

The phase function of the dust coma of comet 67P has been determined from Rosetta/OSIRIS images. This function shows a deep minimum at phase angles near 100°, and a strong backscattering enhancement. These two properties cannot be reproduced by regular models of cometary dust, most of them based on wavelength-sized and randomly oriented aggregate particles. We show, however, that an ensemble of oriented elongated particles of a wide variety of aspect ratios, with radii r ≳ 10 μm, and whose long axes are perpendicular to the direction of the solar radiation, are capable of reproducing the observed phase function. These particles must be absorbing, with an imaginary part of the refractive index of about 0.1 to match the expected geometric albedo, and with porosity in the 60%–70% range.

We report the discovery of a giant planet in the KMT-2016-BLG-1397 microlensing event, which was found by The Korea Microlensing Telescope Network alone. The timescale of this event is t
E = 40.0 ± 0.5 days, and the mass ratio between the lens star and its companion is q = 0.016 ± 0.002. The planetary perturbation in the light curve is a smooth bump, resulting in the classical binary-lens/binary-source (2L1S/1L2S) degeneracy. We measure the V − I color of the (putative) two sources in the 1L2S model, and then effectively rule out the binary-source solution. The finite-source effect is marginally detected. Combined with the limits on the blend flux and the probability distribution of the source size normalized by the Einstein radius ρ, a Bayesian analysis yields the lens mass

Magnetohydrodynamic Modeling of a Solar Eruption Associated with an X9.3 Flare Observed in the Active Region 12673
Authors: Inoue Satoshi , Shiota Daikou , Bamba Yumi , Park Sung-Hong
Published: November 2018

On 2017 September 6, the solar active region 12673 produced an X9.3 flare, regarded to be the largest to have occurred in solar cycle 24. In this work we have performed a magnetohydrodynamic (MHD) simulation in order to reveal the three-dimensional (3D) dynamics of the magnetic fields associated with the X9.3 solar flare. We first performed an extrapolation of the 3D magnetic field based on the observed photospheric magnetic field prior to the flare and then used this as the initial condition for the MHD simulation, which revealed a dramatic eruption. In particular, we found that a large coherent flux rope composed of highly twisted magnetic field lines formed during the eruption. A series of small flux ropes were found to lie along a magnetic polarity inversion line prior to the flare. Reconnection occurring between each flux rope during the early stages of the eruption formed the large, highly twisted flux rope. Furthermore, we observed a writhing motion of the erupting flux rope. Understanding these dynamics is important in the drive to increase the accuracy of space weather forecasting. We report on the detailed dynamics of the 3D eruptive flux rope and discuss the possible mechanisms of the writhing motion.
Coronal Hard X-Ray Sources Revisited

Published: November 2018

This paper reports on the re-analysis of solar flares in which the hard X-rays (HXRs) come predominantly from the corona rather than from the more usual chromospheric footpoints. All of the 26 previously analyzed event time intervals, over 13 flares, are re-examined for consistency with a flare model in which electrons are accelerated near the top of a magnetic loop which has a sufficiently high density to stop most of the electrons by Coulomb collisions before they can reach the footpoints. Of particular importance in the previous analysis was the finding that the length of the coronal HXR source increased with energy in the 20–30 keV range. However, after allowing for the possibility that footpoint emission at the higher energies affects the inferred length of the coronal HXR source, and using analysis techniques that suppress the possible influence of such footpoint emission, we conclude that there is no longer evidence that the length of the HXR coronal sources increase with increasing energy. In fact, for the six flares and 12 time intervals that satisfied our selection criteria, the loop lengths decreased on average by 1.0 ± 0.2 arcsec between 20 and 30 keV, with a standard deviation of 3.5 arcsec. We find strong evidence that the peak of the coronal HXR source increases in altitude with increasing energy. For the thermal component of the emission, this is consistent with the standard CHSKP flare model in which magnetic reconnection in a coronal current sheet results in new hot loops being formed at progressively higher altitudes. The explanation for the nonthermal emission is not so clear.
The Coronal Volume of Energetic Particles in Solar Flares as Revealed by Microwave Imaging

Published: November 2018

The spectrum of gyrosynchrotron emission from solar flares generally peaks in the microwave range. Its optically thin, high-frequency component, above the spectral peak, is often used for diagnostics of the nonthermal electrons and the magnetic field in the radio source. Under favorable conditions, its low-frequency counterpart brings additional, complementary information about these parameters as well as thermal plasma diagnostics, either through gyrosynchrotron self-absorption, free–free absorption by the thermal plasma, or the suppression of emission through the so-called Razin effect. However, their effect on the low-frequency spectrum is often masked by spatial nonuniformity. To disentangle the various contributions to low-frequency gyrosynchrotron emission, a combination of spectral and imaging data is needed. To this end, we have investigated Owens Valley Solar Array (OVSA) multi-frequency images for 26 solar bursts observed jointly with RHESSI during the first half of 2002. For each, we examined dynamic spectra, time- and frequency-synthesis maps, RHESSI images with overlaid OVSA contours, and a few representative single-frequency snapshot OVSA images. We focus on the frequency dependence of microwave source sizes derived from the OVSA images and their effect on the low-frequency microwave spectral slope. We succeed in categorizing 18 analyzed events into several groups. Four events demonstrate clear evidence of being dominated by gyrosynchrotron self-absorption, with an inferred brightness temperature of ≥108 K. The low-frequency spectra in the remaining events are affected to varying degrees by Razin suppression. We find that many radio sources are rather large at low frequencies, which can have important implications for solar energetic particle production and escape.
A Global ILC Approach in Pixel Space over Large Angular Scales of the Sky Using CMB Covariance Matrix
Authors: Sudevan Vipin , Saha Rajib
Published: November 2018

We propose a new internal linear combination (ILC) method in the pixel space, applicable on large angular scales of the sky, to estimate a foreground-minimized cosmic microwave background (CMB) temperature anisotropy map by incorporating prior knowledge about the theoretical CMB covariance matrix. The usual ILC method in pixel space, on the contrary, does not use any information about the underlying CMB covariance matrix. The new approach complements the usual pixel space ILC technique specifically at low-multipole regions, using global information available from the theoretical CMB covariance matrix and from the data. Since we apply our method over the large scale on the sky containing low multipoles, we perform foreground minimization globally. We apply our methods on low-resolution Planck and WMAP foreground-contaminated CMB maps and validate the methodology by performing detailed Monte Carlo simulations. Our cleaned CMB map and its power spectrum have significantly less error than those obtained following the usual ILC technique at low resolution that does not use CMB covariance information. Another very important advantage of our method is that the cleaned power spectrum does not have any negative bias at the low multipoles because of effective suppression of CMB–foreground chance correlations on large angular scales of the sky. Our cleaned CMB map and its power spectrum match well with those estimated by other research groups.

Begoniayenyeniae is a new species of horticultural value known only from the Endau Rompin National Park, Peninsular Malaysia. It is similar to Begoniarajah with which it had previously been confused in the number of tepals and leaf characters. The new species is compared with three similar species, B.foxworthyi, B.rajah and B.reginula and photographs of all four species and descriptions of B.yenyeniae and B.rajah are provided. Molecular analysis using the ndhF-rpl132 chloroplast marker confirms the four species as distinct. Amongst native species, the three variegated species, B.yenyeniae, B.rajah and B.reginula, are some of the most popular Malaysian begonias in cultivation. Based on its restricted distribution, Begoniayenyeniae, under the IUCN Red List Categories and Criteria, is assessed as Critically Endangered.

L’analyse des processus de socialisation se concentre généralement sur les relations entre parents et enfants ou au sein de groupes de pairs. Dans cet article, nous étudions ces processus au sein du couple en décryptant ce que le couple fait au vote et inversement. L’étude s’appuie sur des matériaux quantitatifs, tirés d’un questionnaire administré à la sortie des urnes lors de l’élection présidentielle de 2017 et sur des entretiens réalisés lors de quatre vagues auprès d’individus en couple hétérosexuel. L’influence du couple dans la formation des opinions politiques doit être pensée en relation avec d’autres variables (en particulier, la classe, l’âge et l’héritage politique) et étudiée dans son environnement en prenant en compte les réseaux de chaque conjoint dans une perspective dynamique en termes de « carrières ».
Optical Factors in Increased Best Spectacle-corrected Visual Acuity After LASIK
Authors: Erdem Uzeyir , Muftuoglu Orkun
Published: November 2018

ABSTRACT

PURPOSE: To study the factors that correlate with improved best spectacle-corrected visual acuity (BSCVA) after LASIK.

METHODS: This was a nonrandomized, prospective clinical trial of 850 eyes from 480 patients undergoing LASIK for myopia, hyperopia, and mixed astigmatism. The mean preoperative spherical equivalent refraction was -3.75±4.82 diopters (D) (range: -13.88 to 6.00 D). From this population, 72 eyes (including 22 amblyopic eyes) from 43 patients were found to have improved BSCVA 6 months after LASIK. All patients underwent LASIK with the NAVEX platform. These eyes were analyzed to evaluate factors that correlated with improved BSCVA. Pre- and postoperative BSCVA, refraction, pupil diameter, corneal topography, asphericity (Q value), total aberrations, and higher order wavefront aberrations were analyzed. All wavefront aberrations were measured using the NIDEK Optical Path Difference Scan aberrometer (OPD-Scan) preoperatively and at 6 months postoperatively.

RESULTS: Postoperatively, the mean sphere was -0.44±1.30 D (range: -4.50 to +2.50 D). The mean increase in BSCVA was 0.15±0.09 logMAR. A statistically significant negative correlation was observed between the increase in BSCVA and the preoperative BSCVA (P<.01). Mixed astigmatic and highly myopic eyes are more likely to gain BSCVA after LASIK than moderately myopic (P<.05) and hyperopic eyes (P<.001). In patients with myopia, the amount of BSCVA improvement correlated with the magnitude of the correction (P<.05). The induction of spherical aberration negatively correlated with the increase in BSCVA (P<.05). There were no significant differences between normal eyes and amblyopic eyes with respect to postoperative improvement in BSCVA (P>.05).

CONCLUSIONS: Decreased preoperative BSCVA, lower total spherical aberration induction, and preoperative mixed astigmatism and high myopia correlate with an increase in BSCVA after LASIK. [J Refract Surg. 2006;22: S1056-S1068.]

Authors: Meshi Amit , Camacho Natalia , Lin Tiezhu , Muftuoglu Ilkay K. , Arcinue Cheryl A. , Gaber Raouf , You Qi Sheng , Freeman William R.
Published: November 2018

BACKGROUND AND OBJECTIVE:

To compare subfoveal disciform scars with good and poor vision in patients with neovascular age-related macular degeneration (nAMD).

PATIENTS AND METHODS:

A retrospective case-control study. Twenty-two eyes of 21 consecutively treated patients with nAMD with subfoveal disciform scar and best-corrected visual acuity (BCVA) of 20/63 or better at the final visit were included. Twenty-one eyes of 21 matched patients with disciform scar and final BCVA less than 20/63 served as controls.

RESULTS:

Subretinal pigment epithelium scar location was more common in the good vision group than in the poor vision group (
P
< .001). The mean percent disruption of the ellipsoid and the external limiting membrane layers was significantly greater in poor vision eyes than in good vision eyes from scar formation and throughout follow-up (all
P
< .01).

CONCLUSION:

Preserved photoreceptor layer correlated with good vision in patients with nAMD and subfoveal disciform scar.

Optic Nerve Compression From MIRAgel Implant Migration in a Monocular Patient
Authors: Arepalli Sruthi , Li Ang , Hwang Catherine , Sears Jonathan , Blandford Alexander , Lorek Brandy , Rachitskaya Aleksandra
Published: November 2018

The MIRAgel implantation was popularized in the 1980s as an alternative to silicone for scleral buckle retinal detachment repair. However, long-term follow-up has revealed that the implants can expand, creating globe compression and potentially visually devastating intraocular invasion. The authors document a 33-year-old monocular male patient presenting 20 years after MIRAgel implantation with extensive expansion, posterior migration, globe compression, and possible optic nerve compression. Debulking of the MIRAgel stabilized the vision and restored affected extraocular movements. The authors highlight that posterior MIRAgel migration can cause optic nerve compression, and implant debulking may require a multi-disciplinary approach.

Morphological Difference of Choroidal Vasculature Between Polypoidal Choroidal Vasculopathy and Neovascular AMD on OCT: From the Perspective of Pachychoroid
Authors: Lai Kunbei , Zhou Lijun , Zhong Xiaojin , Huang Chuangxin , Gong Yajun , Xu Fabao , Ma Li , Chen Guandi , Cheng Lin , Lu Lin , Jin Chenjin
Published: November 2018

BACKGROUND AND OBJECTIVE:

To investigate the morphological difference of choroidal vasculature between polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (nAMD) on optical coherence tomography (OCT).

PATIENTS AND METHODS:

One hundred eighty-nine patients with macula-involved PCV (n = 107) or nAMD (n = 82) were retrospectively reviewed. The subfoveal choroidal thickness (SFCT) and thickness of the Haller's layer were determined on enhanced depth imaging optical coherence tomography (EDI-OCT). The mean diameters of subfoveal large choroidal vessels were also calculated.

RESULTS:

Both the SFCT (257.31 μm ± 100.50 μm vs. 209.95 μm ± 97.51 μm) (
P
< .01) and the thickness of the Haller's layer (213.68 μm ± 82.65 μm vs. 159.67 μm ± 79.86 μm) (
P
< .01) were greater in PCV patients than nAMD patients. The ratio of thickness of the Haller's layer to the SFCT was higher in the PCV group (0.83 ± 0.07) than the nAMD group (0.7 5± 0.11) (
P
< .01). The mean diameter of subfoveal large choroidal vessels was greater in PCV patients (163.55 μm ± 62.23 μm vs. 112.81 ± 58.87 μm) (
P
< .01).

CONCLUSION:

Choroidal thickening and dilation of large choroidal vessels were commonly seen in PCV patients, supporting that PCV belongs to the pachychoroid spectrum disorders and might be a different entity from nAMD.

ALTERNATIVE TECHNIQUES TO IMPROVE INDOOR ENVIRONMENTAL QUALITY
Authors: Sumanasekara S.A.S.L. , Jayasinghe C.
Published: November 2018

Most of the time people stay in confined environments and thus are highly exposed to accumulated indoor pollutants. Indoor environmental pollution has been identified as one of the most prevalent causes for health problems, such as sick building syndrome. These health problems have been magnified with the introduction of energy efficient building concepts, coupled with limited fresh air supply, which has compromised the effective means of air purification. Further, the frequent use of chemical substances for numerous purposes contributes to indoor air pollution. Therefore, investigation of alternative techniques to improve indoor environmental quality has been extensively studied in the last two decades. In Sri Lanka, there is a potential for studying indigenous techniques to improve indoor air quality. However, verification of such techniques and quantification of their impacts has not been given much attention. The research focus of this paper is to identify those material substances that can be used to absorb pollutants and lessen their harmful impacts and thereby improve air purification. A chamber study was used to quantify air purification using different material substances and considering the following parameters: total volatile organic compound (TVOC) and Carbon Monoxide (CO) levels. Further, the results obtained in the chamber study were assessed for its projection to real applications by comparison with a study conducted in an actual indoor space. The outcome of the study has revealed that the indigenous knowledge of Sri Lanka can be used to improve indoor air quality.
SHEARING LAYERS CONCEPT AND LEED GREEN BUILDINGS IN BOTH RATING SCHEMES AND CERTIFIED PROJECTS
Authors: Pushkar Svetlana , Verbitsky Oleg
Published: November 2018

The Leadership in Energy and Environmental Design (LEED) for New Construction and Major Renovations v3 (NC) and LEED for Existing Buildings: Operations and Maintenance v3 (EB) schemes were studied to examine the application of the shearing layer concept to green buildings. The manners in which (i) rating systems in their current configurations and (ii) certified projects in their practical applications treated the long life-expectances in buildings and short life-expectancies in systems were questioned. To maximally reduce nondemonic intrusion, we studied only those states in the United States in which statistically viable numbers of projects had been completed in 2016. A two-way mixed analysis of variance (ANOVA) model was used to evaluate the interaction between two types of buildings (i.e., NC vs EB) and two sets of sub-layers (i.e., Site, Structure, and Skin from the Building layer and Services, Space Plane, and Stuff from the Service layer). The discrepancy in the case of a new building and the similarity in the case of a renovated building between rating schemes and certified projects were revealed: (i) the NC rating scheme prefers to emphasize the Service layer (SL), whereas newly constructed projects prefer to emphasize the Building layer (BL) due to the high performance of the Site and Structure sub-layers; (ii) the EB rating scheme prefers to emphasize the Service layer, as do renovated building projects, due to the high performance of the Stuff sub-layer.

Published: November 2018

The quality of entrepreneurship education at the collegiate level is correlated with its sustainability. Existing studies have focused on the construction and method selection of evaluation systems for entrepreneurship education but have lacked concrete analyses of individual effectiveness. Through a micro-perspective, this study conducted a data envelopment analysis to assess the efficiency of entrepreneurship education in eight higher learning institutions. The input criteria comprised the number of courses and available funding, whereas the output criteria consisted of the number of awards won in two major intercollegiate contests and the initial employment rate. In addition, this study further investigated the most efficient schools to find students' opinions on course content and entrepreneurial needs. The findings in this study may serve as a reference for optimizing collegiate-level entrepreneurship education resources, clarifying developmental goals, and improving resource efficiency.

The aim of this research is to identify the factors that could influence customers' attitudes and intentions to continuing online purchases in reserving a hotel room by using the theory of perceived characteristics of innovating scale and the theory of reasoned action as the main theories. Multiple regression analysis was utilized to analyze the relationship between the independent variables and customer attitude and intentions as the dependent variables. The results concluded that all the variables in perceived characteristics of innovating scale had an influence on attitude, and the variables in the theory of reasoned action except online subjective norms had a negative influence on intention. Visibility had the strongest impact on customer attitude, and offline subjective norms also became the strongest influence on intention to continue online purchases.

This article investigates the reasons most African households are not using the internet and discusses the policy implications for bridging the digital divide. The International Telecommunication Union (ITU) reports that at the end of 2014, only 7 percent of households in LDCs, most of whom are in Africa, had Internet access. This study analyses data from the ITU database and other sources to identify the determinants of the digital divide in Africa. Results show that peculiar challenges such as affordability and digital literacy do influence the percentage of African households who do not use the internet.
Factors affecting Velcro-covered balls when used as a sampling device for wool ofAdelges tsugae(Hemiptera: Adelgidae)
Authors: Fidgen Jeffrey G. , Fournier Ronald E. , Whitmore Mark C. , MacQuarrie Chris J.K. , Turgeon Jean J.
Published: November 2018

Adelges tsugaeAnnand (Hemiptera: Adelgidae) has caused extensive mortality of hemlocks (Tsuga(Endlicher) Carrière; Pinaceae) in the eastern United States of America and was discovered recently in Nova Scotia, Canada. We evaluated the use of a Velcro-covered racquetball as a sampling device forA. tsugaewool. Specifically, we report on improvements to an earlier design and evaluate several factors seen in routine sampling that influence the ability of the ball to trap and retain adelgid wool. Velcro was found to be critical for trapping and retaining adelgid wool on the ball during flight and landing. Wooden beads, inserted in the ball, reduced deflection during flight and bounce during landing. Higher probability of trapping wool on the ball was associated with an ascent through the crown, with increasing diameter and density of ovisacs on branch tips, and with increasing abundance of woolly twigs on the forest floor. Higher probability of retaining wool on the ball was associated with Velcro surface area and with amount and location of wool loaded on the ball. These modifications improved detection surveys forA. tsugaein general.
La violenza domestica assistita

Published: November 2018

Il problema della violenza domestica ha assunto oggi grande rilevanza, sia nel campo della ricerca scientifica che nel campo delle politiche sociali, dell’azione penale e della tutela legale delle vittime. Purtroppo, bisogna rilevare che la grande attenzione mediatica concentratasi sui casi di violenza domestica, ha prodotto una serie di errate convinzioni e luoghi comuni, che rischiano di affliggere tanto il giudizio comune quanto quello legale, assai più delicato per le implicazioni dirette e indirette sui soggetti coinvolti. Una scarsa chiarezza sulle caratteristiche del fenomeno incide su tutte le fasi e le tipologie di valutazione deputate all’accertamento dei casi specifici e, per naturale estensione, anche sui programmi di prevenzione e sostegno, dedicati in particolare alle vittime
Commensurated subgroups in tree almost automorphism groups
Authors: Le Boudec Adrien , Wesolek Phillip
Published: November 2018

We prove that the almost automorphism groups AAut

(\mathcal T_{d,k})

admit exactly three commensurability classes of closed commensurated subgroups. Our proof utilizes an independently interesting characterization of subgroups of AAut

(\mathcal T_{d,k})

which contain only periodic elements in terms of the dynamics of the action on the boundary of the tree.

Our results further cover several interesting finitely generated subgroups of the almost automorphism groups, including the Thompson groups

F, T

, and

V

. We show in particular that Thompson’s group

T

has no commensurated subgroups other than the finite subgroups and the entire group. As a consequence, we derive several rigidity results for the possible embeddings of these groups into locally compact groups.

Published: November 2018

Abstract. Although vessel-based acoustic sounding technique is accurate, however it is typically constrained by high operating costs, logistic difficulties and limited spatial coverage. It seems it is necessary to employ an alternative approach that can reduce the aforementioned high operation cost. The development of the imagery-derived bathymetry has brought in the new revolution in hydrography. The paper highlights the application of incorporating satellite remote sensing techniques to extract bathymetry information from the freely downloadable Landsat-8 satellite images. In this study, two different band ratio transform empirical models have been utilised to transform the reflected radiances of green and blue bands into bathymetry depths at the coastal region adjacent to Tanjung Kupang, Strait of Johor, Malaysia. The inland swampy area is vegetated by lavish mangroves while the shoreface is fronted by flat slopes with turbid suspended sediment. In the course of experiment, the results from Stumpf et al.’s model and Dierssen et al.’s model show a reasonable agreement, with similar correlation coefficient (r) of 0.76 between the imagery-derived depths and in-situ bathymetry depths from vessel-based sounding. The Stumpf et al.’s model has achieved root mean square error (RMSE) of 0.885 metres and mean absolute error (MAE) of 0.631 metres; while Dierssen et al.’s model delivers RMSE of 0.878 metres and MAE of 0.629 metres respectively. Although these two algorithms are slightly different, however the end results produced are quite close in this study. The results show that both empirical models represent a promising outcome and can be used to complement data from vessel-based single beam sounding, which is normally obtained at medium to course profiling resolution for the purpose of survey reconnaissance and survey planning.

Abstract. The rapid development of a country has resulted in limited land use. This is indirectly encouraging multilayer development (strata) especially for the development of residential properties such as condominiums, apartments and others. The idea of having 3D database for the cadastral system has been discussed for a good and efficient management in Malaysia. The development in 3D GIS will make a 3D cadastral realizable. In Malaysia, the current 2D cadastre system is regularly updated by the National Mapping Agency (NMA) and Land Offices (LO). However, this 2D information may not be able to serve complex situations. The 3D strata acquisition and 3D modelling are important for strata title to manage the Right, Restriction and Responsibility (RRRs). This means needs to the system extended into 3D cadastre environment. One of the data acquisition techniques is utilizing LiDAR data to solve the problem. 3D geospatial objects could be generated from the captured points cloud. The NMA attempts to make use of LiDAR datasets for strata registration purposes. This paper also discuss the needs the 3D strata registration via XML and IndoorGML for future 3D strata development in Malaysia.
The computation of bending eigenfrequencies of single-walled carbon nanotubes based on the nonlocal theory
Authors: Bocko Jozef , Lengvarský Pavol , Huňady Róbert , Šarloši Juraj
Published: November 2018

Abstract. In this work, a recently proposed nonlocal theory of bending is
used in the analysis of eigenfrequencies of single-walled carbon nanotubes
(SWCNTs). The nanotube vibration is analyzed in the form of a homogenized
continuum. Classical treatment where a nanotube is approximated by standard
beam theory, is replaced by the more sophisticated nonlocal method of
material interactions where a nonlocal parameter is used. The
eigenfrequencies are computed by the combination of analytical as well as
numerical methods for four different carbon nanotube (CNT) supports. Various
types of supports are considered for the analysis: fixed–simply supported,
fixed–free, simply–simply supported and fixed–fixed. Due to the huge
amount of computed data, only outcomes of eigenfrequency computations for the
nanobeams of armchair type with fixed and simply supported ends, and
different nonlocal parameters are represented in the form of graphs at the
end of the article. The study shows how the nanotube eigenfrequencies depend
on nonlocal parameters as well as on the length and diameter of CNTs. The
obtained results are in good agreement with the results published in papers
which were gained by different procedures.
Parameters of Profitability: Evidence From Conventional and Islamic Banks of Bangladesh
Authors: Muhiuddin K. M. Golam , Jahan Nusrat
Published: November 2018

This paper evaluates the commercial banks of Bangladesh in terms of profitability dimension of performance and also examines the impact of selected determinants and banking system on this dimension of performance. Evaluation of trend in profitability of listed commercial banks of Bangladesh reveals that, on an average, profitability is exhibiting a decreasing trend over the selected period; however, the profitability performance of Islamic banks remained rather high compared to Conventional banks. Profitability measured by Return on Asset is found to be significantly affected by the bank-specific factors, industry-specific factor and the banking system. However, macro-economic factors evidently have no significant impact on profitability of commercial banks of Bangladesh.
A ação política como caso de polícia no Brasil
Authors: Freitas Veronica Tavares de
Published: November 2018

Vivemos no Brasil pouco mais de um século de uma deficiente República, marcada por dois longos processos ditatoriais que contribuíram para a conformação das características da repressão estatal diante dos movimentos sociais. Nesse bojo, o presente artigo analisa como 2013 pode ser compreendido como um momento de inflexão pós-redemocratização, no qual cresceu a desvinculação entre os detentores do poder e os cidadãos, apresentando-se como um de seus aspectos o deslizamento da ação política para a arena penal. Em associação com o tratamento dos ativistas como caso de polícia, pode-se identificar avanços institucionais posteriores na tipificação penal dos repertórios de confrontação dos movimentos sociais. Além da revisão da literatura do campo, este artigo parte da análise documental legislativa, bem como da cobertura midiática para demarcação dos principais acontecimentos desde 2013. Como aporte teórico será utilizada a Teoria do Confronto Político, a partir da qual pretende-se enxergar o período iniciado em junho de 2013 na qualidade de um processo, com o olhar voltado para a relação entre ativistas e os agentes estatais para uma leitura do complexo cenário nacional.

Authors: Córdoba Martínez Fanny , Castelblanco Castro Jenny Lucía , García-Martínez Álvaro
Published: November 2018

En este artículo se analizan las habilidades cognitivo-lingüísticas (describir, explicar, justificar y argumentar) de cinco estudiantes en ciclo tecnológico del programa Gestión de la Producción Agroindustrial, de la Universidad Tecnológica de Bolívar, en convenio con Edupol, en modalidad virtual a distancia por convergencia de medios, cuando abordan procesos industriales relacionados con la química industrial. La metodología es cualitativa y los resultados muestran que en los educandos se pueden mejorar dichas habilidades, de forma sincrónica y asincrónica, desarrollando los contenidos y la escritura social a través de una comunicación dialógica que genere un entorno de aprendizaje que ponga en juego los principios del constructivismo en la educación virtual a distancia.
Análisis de la percepción de la educación para la sostenibilidad por parte del profesorado de Educación Secundaria y Bachillerato
Authors: Risco Torres Miguel , Cebrián Gisela
Published: November 2018

Este estudio de caso sobre el colegio Claret de Madrid pretende estudiar la percepción del profesorado de Educación Secundaria sobre la educación para la sostenibilidad (ES), así como las diferencias demográficas al respecto (edad, género, experiencia y especialidad). Se ha adaptado un cuestionario con 50 posibles respuestas a una pregunta abierta, que debían ser puntuadas por los docentes según su conformidad con estas. Tras la obtención de las puntuaciones y testar el efecto de las variables demográficas, los resultados revelan una percepción general –pero no homogénea– positiva de la ES. Los docentes con menos edad y experiencia muestran puntos de vista más favorables, a pesar de no dominar dicha disciplina. Este estudio pone de manifiesto la necesidad de mejorar la formación inicial y continua en ES del profesorado.
‘Cylinder of conflict’ as an extended model of environmental conflicts in the context of mining activity
Authors: Belzyt Joanna Iza , Badera Jarosław
Published: November 2018

Based on the discussion on the sources and mechanisms of environmental conflicts (especially those related to mining activities), it was pointed out that the structural model of conflict (the so-called ‘circle of conflict’, introduced by Ch. Moore in 1986) can, and even should be, supplemented with additional, new items. As a result, it forms a spatial solid, i.e. ‘cylinder of conflict’. The authors believe that the addition of supplementary elements will form a solid, with emotions and language codes as the ends, which may be both the cause and the result of the conflict. The authors decided to supplement the ‘circle of conflict’ based on the analysis of the literature and their own experiences. The authors paid attention to the change in the dynamics of the system, in which the remaining causes of the conflict ‘mix’ and collide constantly, overlapping and growing, which may lead to escalation and final disruption of relations between stakeholders. Thus, the discussed model itself takes on an even more dynamic character than the ‘circle of conflict’. According to the authors, it is a good metaphor for the issues discussed, and probably also for any other conflicts.
Preliminary characteristics of rare earth elements and other trace elements in fine-grained deposits from the Triassic-Jurassic transition in the former Mid-Polish Trough
Authors: BRAŃSKI Paweł
Published: November 2018

Fine-grained siliciclastic rocks from the Triassic-Jurassic transition (Rhaetian–Hettangian) in the former Mid-Polish Trough were the subject of the geochemical study at the Polish Geological Institute – National Research Institute in Warsaw. Ninety-four samples of claystones and mudstones from six archived drill cores were analysed by ICP-MS and XRF for rare earth elements (REE) and other trace elements. The results indicate that the sources of most of the claystones and mudstones were sedimentary rocks of the upper continental crust of old cratonic areas, where the protolith had a moderately felsic character. Weathering and recycling processes modified the original chemical composition to some extent. However, during Rhaetian and early Hettangian, some geochemical data in the south-eastern segment of the MPT suggest significant input from a mafic volcanic protolith. Moreover, a clear enrichment in rare-earth elements was observed in few samples, caused by admixtures of accessory minerals (being a main carrier of REE). Nevertheless, based on currently obtained data, the Rhaetian–Hettangian concentrations of REE (and other trace elements) in the MPT are low and they are of scientific indicative significance, not of raw material importance.
Problems of social acceptance of mining activities and ways of minimizing them in the EU countries
Authors: RADWANEK-BĄK Barbara
Published: November 2018

Social acceptance for mining activity is one of the important elements determining its success. In addition to formal and legal conditions related to the nature of protection and spatial planning, it is one of the major barriers that limit or even hold back this activity. Over the last several years, a constant increase in such unacceptance can be observed in both Poland and most of the European countries, although the degree of occurrence of this phenomenon is diverse. It is confirmed by surveys carried out by the author as part of the already completed EU Minerals4EU project. The paper discusses the results of these studies and attempts to explain the reasons for the negative attitude of societies to mining activity. The activities undertaken to change the attitude are also presented, in particular the Social Impact Assessment (SIA). The objectives of the assessment are similar to the purposes of generally applicable Environmental Impact Assessments: identification of all possible limitations of planned exploitation, and their evaluation and minimization, necessary to obtain a favourable environmental decision, and, in the case of the SIA, to obtain social acceptance for the planned mining investment. In some EU countries, e.g. Denmark and Greenland, the development of a separate SIA report is a compulsory element of concession proceedings. The paper discusses the adopted formal scope of this document and the advantages of such a solution, enabling the anticipated operation of the future investor to achieve the planned goal.
