El patrimonio etnológico: un patrimonio cultural sin régimen jurídico.
Authors: Alegre Ávila Juan Manuel
Published: June 2019

En el siguiente artículo se realiza un recuento de la normativa estatal, autonómica e internacional sobre el tratamiento que se da en los diferentes textos legales al patrimonio etnográfico o etnológico e industrial, en especial al de carácter inmaterial. El autor describe, a través de una recorrido exhaustivo por la legislación autonómica, cómo las comunidades no han introducido novedades sustanciales en el esquema de protección descrito por la Ley de patrimonio histórico español, que se articula en dos vectores: por una parte la remisión, en punto a la protección y tutela de los de carácter etnográfico, al régimen general establecido en aquella para los bienes, en tanto que cosas en sentido civil, muebles e inmuebles; y, por otra, la documentación de los conocimientos y actividades de índole etnográfico. Sí ha encontrado eco este tipo de patrimonio en los textos internacionales. La Convención para la Salvaguarda del patrimonio Cultural Inmaterial, suscrita en 2003, y ratificada por España en 2006, en vigor a día de hoy, también será motivo de estudio en el texto que se presenta a continuación.

Published: June 2019

Poligami dewasa ini masih menjadi perdebatan, terutama terkait dengan keberadaan asas monogami relative yang berlaku di Hukum Perkawinan Indonesia, dimana membuka peluang untuk dapat melakukan poligami. Hal ini membuka celah hukum praktik poligami yang tidak terkontrol. akibatnya berdampak pada kaum wanita jika poligami tidak dilakukan dengan hati hati. Penekanan terhadap asas monogami relatif terdapat pada pemberian izin istri pertama untuk melakukan poligami. Dalam hal izin saja,berpotensi untuk merusak hubungan rumah tangga sangatlah besar dan yang menjadi korbannya tentu pada pihak wanita. Tentu poligami sekarang dengan poligami pada masa Rosulullah SAW berbeda. Diperlukan peran negara dalam memperketat aturan dalam praktik poligami di Indonesia agar perlindungan hukum terhadap wanita lebih terjamin. Berbeda dengan negara Malaysia sebagai Negara dengan sistem Common Law, yang menganggap poligami sebagai sebuah tindakan kriminal. Perbedaannya terletak pada pembebanan pada syarat, alasan dan prosedur yang lebih ketat. Walaupun sistem hukum antara malaysia dengan Indonesia berbeda namun pengetatan terkait dengan syarat, alasan dan prosodur diharapkan dapat juga berlaku di Indonesia untuk memberikan perlidungan hukum terhadap wanita.

Published: June 2019

There is a shortage of knowledge about how baseball cleat design may impact athletes. The purpose of this experiment was to determine if the height of the baseball cleat affected performance, perception of the cleat, and ankle range-of-motion. Thirteen subjects participated in the study, and each subject performed three drills (base-running, 5:10:5 "pro agility," and hitting) in both high-top and low-top baseball cleats. Performance time was measured for the first two drills. Perception of comfort, heaviness, shoe climate (heat), stability, and traction were measured for all three drills using 10-cm visual analog scales (VAS). Ankle range-of-motion (dorsiflexion, plantarflexion, eversion, and inversion) was measured using goniometry in both cleats, plus socks-only as baseline control. Shoe height did not significantly affect completion time in either the base-running drill (6.1±0.1 sec. in high-top vs. 6.1±0.1 sec. in low-top) or pro-agility drill (4.8±0.1 sec. in high-top vs. 4.6±0.1 sec. in low-top). There were significant differences in perception of heat (6.4 in high-top vs. 4.6 in low-top; p<.001), stability (6.9 in high-top vs. 5.1 in low-top; p=.001), and heaviness (6.0 in high-top vs. 4.1 in low-top; p<.001), but not in perception of comfort (6.1±2.0 in high-top vs. 6.6±1.5 in low top) or traction (7.3±2.0 in high-top vs. 7.4±1.5 in low-top). There were significant differences between high-top and low-top cleats in plantarflexion (42.5° in high-top vs. 47.5° in low-top; p=.033), eversion (7.9° in high-top vs. 11.3° in low-top; p=.003), and inversion (12.8° in high-top vs. 16.6° in low-top; p=.044), but not dorsiflexion (8.2° in high-top vs. 10.9°). For baseball players concerned about excessive ankle movements during play, these results suggest that using a high-top baseball cleat might reduce ankle range-of-motion without impairing performance or feeling burdensome.

Transcription of nanos-1 in Zebrafish Embryos is not Affected by Bisphenol A: Evaluated Using Quantitative Real-Time PCR
Authors: Babich Bridget , Roba George , Safura Siti Sarah , Callahan Kevin , Freeman Edward
Published: June 2019

The presence of primordial germ cells (PGCs) is crucial for proper gonad formation in zebrafish (Danio rerio). The many aspects of PGC migration that allow these cells to reach the proper location at the gonadal ridge include receptors, ligands, germ plasm components, and internal maintenance of PGCs. Any one of these factors could be affected by endocrine-disrupting chemicals (EDCs), which have been shown to alter the directed migration of these cells during early embryonic development. Based on recent research wherein the EDC bisphenol A (BPA) inhibited normal PGC migration, we have used the same dose of BPA to determine the impact of BPA on a gene central to proper germ cell migration. Zebrafish embryos were exposed to BPA, and the levels of the target gene nanos-1 were analyzed using quantitative real-time PCR (q-PCR). The target gene nanos-1 is a critically important germplasm component that allows for survival and proper migration of PGCs. The q-PCR results showed that BPA did not affect the transcription level of nanos-1 in zebrafish embryos.

Investigation of Atmospheric Aerosol Size Distributions from Ground-Based Solar Spectrometer Measurements Synthesized with Satellite Data
Authors: Kuhr Dane , Whitten Adam
Published: June 2019

Data collected by a ground-based solar spectrometer at Collegeville, MN, was used to generate Aerosol Optical Depths (AODs) throughout the 2017 calendar year. The AOD data was then visualized at 13 selected wavelengths throughout the year and analyzed in comparison to satellite imagery, upper air charts and backwards trajectories of air masses moving towards Central Minnesota in order to determine key dates of interest that correspond to times before (20170615), during (20170729), and at the conclusion of (20170914) forest fires that burned in British Columbia (BC) during the summer of 2017. The data from these specific days were analyzed further by inputting the maximum and minimum AODs for each day into a Parameter Based Particle Swarm Optimization (PBPSO) algorithm in order to generate bimodal lognormal particle size distributions. The bimodal distributions were chosen because they carry more information about the aerosol loads across the entire spectrum of particle radii. The resulting distributions show an increase in number density and decrease in median radius in the Aitken mode during the BC forest fires and a relatively constant (within uncertainty) number density of accumulation mode particles at daily maximum AODs. Comparing the resulting bimodal lognormal distribution for daily minimum AODs (where evaporation and other diurnal effects are at a minimum) shows an increased number density of Aitken mode particles by two orders of magnitude from pre- to post-forest fires. This measured increase in the number density of smaller radii particles due to forest fires illustrates the PBPSO’s capability of distinguishing variations in atmospheric aerosol particle number size distributions in the Aitken mode based on data collected by the Kipp-Zonen PGS-100 solar spectrometer.

Challenges and
possibilities for environmentally sound recycling of ships and composite boats
in European union
Authors: Premur Vitomir , Anić Vučinić Aleksandra , Melnjak Ivana , Radetić Lucija
Published: June 2019

In this paper are presented challenges that countries of European Union face when recycling ships and composite boats. European ship owners control over 40 % of the world’s merchant ship fleet, with Greece as the top ship-owning country
globally. Nowadays, ship recycling is being regulated and positive progression
was made towards it since steel industry belongs in world’s top five and stable
market and makes recycling of scrap metals from ships attractive. On the other
hand, yachts, sailing boats and small boats are mainly made from composite
materials because of their favourable properties, making them great investment,
but end-of-life management is more complicated and not quite regulated by the
law yet. Unlike commercially oriented ships, which are constantly in move and
disposed when the maintenance costs of the vessel start to exceed possible
revenue, old boats for recreational and tourism-oriented purposes most rarely
move. Hundreds of thousands lie in marinas and are abandoned due to the
maintenance costs thus discouraging the owners from keeping it. Hence, a
growing number of marinas worldwide will have the problem of boat disposal in a
sustainable way in the future. In this paper is given short summary on waste
ships and boats management issues. The emphasis is on waste management of small composite boats

Orthokeratology lenses and myopia control
Authors: Nagorsky Pyotr , Kikhtenko Nikolai , Milyukhina Vera
Published: June 2019

Purpose: To estimate the stabilizing effect of orthokeratology lenses (ortho-K, OK-lenses) on myopia progression by evaluating axial eye growth dynamics and clinical refraction.
Material and methods. Ortho-K group consisted of 68 children (135 eyes) aged 7–17 years (mean age 12.2) with progressive myopia (initially -0.75–6.75 D).
Observation period varied from 7 to 30 months (mean period 11.68±4.39). All patients used OK-lenses for overnight wear. The control group consisted of 90 patients (180 eyes) with myopia who were prescribed single vision spectacles for vision correction. Comparative analysis was performed for clinical refraction parameters as well as for axial length (AL). The data was obtained with the use of IOL-Master optical biometer (“Carl Zeiss”).
Results. The parameters were stable in patients of ortho-K group: axial length, subjective and objective clinical refraction, the required power of corrective lenses. However, the parameters changed significantly in the control group during the observation period: uncorrected visual acuity (UCVA) decreased, the required power of corrective lenses increased, the indices of objective clinical refraction strengthened, annual gradient of progression (AGP) amounted to 0.26±0.19 and 0.16±0,39 mm in patients with low and moderate myopia, respectively.
Conclusion. The use of OK-lenses ensures a significant deceleration of myopia progression in children. The results obtained suggest a wider use of ortho-K among pediatric ophthalmologists in their clinical practice as it is an effective preventive and therapeutic method for patients with progressive myopia.
Efficacy of myopia control by combination of orthokeratology and instillation of low-concentration atropine
Authors: Tarutta Elena , Verzhanskaya Tatiana
Published: June 2019

Majority of reports regarding methods of myopia control are devoted to the use of orthokeratology lens¬es (OKL) or atropine. The purpose of the study was to estimate the efficacy and safety of using OKL in com¬bination with instillation of 0.01% atropine drops for myopia control in children.
Material and methods. Prospective cohort study in¬cluded 34 patients (68 eyes) aged 8 to 14 years old with acquired myopia. Groups with low (17 patients, 34 eyes), moderate (12 patients, 24 eyes) and high (5 patients, 10 eyes) myopia were identified and examined prior to and 6, 12 and 18 months after adding 0.01% atropine instillations to OKL wearing. To assess the degree of pro¬gression of myopia in dynamics the following parameters were evaluated: refraction (by Huvitz MRK 3100P, axial length (AL) by IOL-Master, “Carl Zeiss”, (Germany), ampli¬tude of accommodation (AA) by Grand Seiko WRK-5100K, positive-relative accommodation (PRA), pseudoaccom¬modation (PA) and annual gradient of progression (AGP).
Results. The most noticeable effect was observed in patients with low myopia. In patients with low myopia, the rate of annual progression gradient decreased by 3.4 times by 18th month of atropine use; therefore a condition close to stabilization of myopia progression occurred. The data is statistically significant. In patients with moderate myopia, despite the de¬crease of the AGP within 6-month period of atropine use by 3.7 times, the increase of APG was observed by 12th month of atropine use, which continued until 18th month of observation. In spite of this, in comparison with baseline indices, the decrease in the rate of myo¬pia progression was obtained. The data is statistically significant.
In patients with high myopia, change in the AGP was not ob¬served within the 6-month period of atropine use; afterwards, a gradual decrease in the rate of myopia progression was noted: AGP decreased by 1.2 times by 12th month. By 18th month of atropine use, AGP decreased by 1.5 times compared to its initial level. The data is statistically significant.
Evidently, the inhibitory effect of OKL, which is de¬termined by optical factors such as peripheral myopic defocus, even in combination with atropine, is not suf¬ficient to halt the progression of high myopia, because of structural and biomechanical changes of the sclera.
Conclusion. Based on the preliminary results ob¬tained, 100% efficacy of a long-term instillation of low-concentration atropine cannot be claimed, howev¬er, the positive effect does exist and therefore the study continues.
Regarding effectiveness of atropine use in children and adolescents with progressive myopia (literature review)
Authors: Myagkov Alexander , Verzhanskaya Tatiana , Shibalko Ekaterina
Published: June 2019

The issue of myopia prevention or myopia control is becoming more and more relevant every year. The approaches to myopia pathogenesis and myopia control have changed fundamentally, stereotypes have been dispelled, hypotheses and numerous studies are becom¬ing the basis of new scientific developments. However, the reality dictates the necessity to integrate the updated evidence based medicine data regarding myopia control into the clinical ophthalmological practice.
The main reason that concerns the professional community is a growing prevalence of progressive my¬opia among children and adolescents around the world.
The incidence of myopia among the adult population of European countries and the United States is estimat¬ed at 20-50%, whereas in Asian countries it amounts to 60-90%. In recent years, there was an increased interest towards the use of conservative methods of treatment in order to stabilize myopia, including the use of pharmacological agents. The publications from 1964 up until today were analyzed in the following review. They were focused on the results of studies that showed the ef¬fect of different concentrations of atropine on myopia progression in children and adolescents who had been observed during a maximum period of 5 years.
Conclusion. According to numerous studies, low-concentration atropine (0.01%) is an effective mean to slow the progression of myopia and stabilize refraction. In addition, long-term therapeutic use of this particular concentration of atropine is associated with the least frequent occurrence of negative side effects.

Currently in the area of Unmanned Aerial Vehicles (UAVs), there are research studies that incorporate this renewable energy technology to increase the vehicle’s autonomy. This technique also needs particular construction techniques and electronic boards, designed to reduce weight and increase the efficiency of all solar systems on board the UAV. As is well known, the amount of generated solar energy could be increased throughout a day a sun tracking technique is added. The present paper proves that the roll angle of a fixed wing UAV can be used to track the sun to increase the energy generated by the solar panels placed on the wing. In that case, the plane’s attitude must be compensated with the yaw angle control to be able to perform a photogrammetric mission. This will be achieved using a control strategy based on the super-twisting technique that ensures convergence in finite time even in the presence of bounded perturbations. The design of the control laws as well as the numerical simulation and real flight results are shown to validate the use of the sun tracking system.

The emergence of affordable unmanned aerial systems (UAS) creates new opportunities to study fire behavior and ecosystem pattern—process relationships. A rotor-wing UAS hovering above a fire provides a static, scalable sensing platform that can characterize terrain, vegetation, and fire coincidently. Here, we present methods for collecting consistent time-series of fire rate of spread (RoS) and direction in complex fire behavior using UAS-borne NIR and Thermal IR cameras. We also develop a technique to determine appropriate analytical units to improve statistical analysis of fire-environment interactions. Using a hybrid temperature-gradient threshold approach with data from two prescribed fires in dry conifer forests, the methods characterize complex interactions of observed heading, flanking, and backing fires accurately. RoS ranged from 0–2.7 m/s. RoS distributions were all heavy-tailed and positively-skewed with area-weighted mean spread rates of 0.013–0.404 m/s. Predictably, the RoS was highest along the primary vectors of fire travel (heading fire) and lower along the flanks. Mean spread direction did not necessarily follow the predominant head fire direction. Spatial aggregation of RoS produced analytical units that averaged 3.1–35.4% of the original pixel count, highlighting the large amount of replicated data and the strong influence of spread rate on unit size.

Authors: De Pretis Francesco , Osimani Barbara
Published: June 2019

Today’s surge of big data coming from multiple sources is raising the stakes that pharmacovigilance has to win, making evidence synthesis a more and more robust approach in the field. In this scenario, many scholars believe that new computational methods derived from data mining will effectively enhance the detection of early warning signals for adverse drug reactions, solving the gauntlets that post-marketing surveillance requires. This article highlights the need for a philosophical approach in order to fully realize a pharmacovigilance 2.0 revolution. A state of the art on evidence synthesis is presented, followed by the illustration of E-Synthesis, a Bayesian framework for causal assessment. Computational results regarding dose-response evidence are shown at the end of this article.
Effect of Tidal Stage on Sediment Concentrations and Turbulence by Vessel Wake in a Coastal Plain Saltmarsh
Authors: Styles Richard , Hartman Michael A.
Published: June 2019

Vessel generated waves can impact shoreline stability and habitat structure in many waterways. Sheltered regions, such as coastal plain saltmarshes, support fragile ecosystems and can be particularly vulnerable to the effects of unregulated vessel operations. Instruments for measuring currents and sediment concentration were deployed in a coastal plain saltmarsh to examine the small-scale physical characteristics of the vessel wake generated by recreational craft typical of this environment. The response to vessel wake varied sharply depending upon the stage of the tide. At low tide, waves breaking on the exposed bank produced high concentrations of suspended material that were transported offshore through turbulent diffusion. When the water elevation exceeded the toe of the marsh scarp, the concentration and turbulent kinetic energy exhibited less of a statistically significant variation in response to vessel passage. For the most energetic flows, the vessel orbital velocities were dwarfed by turbulent fluctuations generated by the sheared tidal boundary layer. While further research is required, preliminary findings indicate that the dissipation of vessel wake energy may stimulate or enhance shear generated turbulence if the characteristic wave period is similar to the characteristic time scale of the energy containing eddies.

Herein, the amino-capped TiO2 nanoparticles were synthesized using tetrabutyl titanate and amino polymers by a two-step sol-gel and hydrothermal method technique for the fabrication of functional cotton fabric. The prepared TiO2 nanoparticles and the treated cotton fabric were characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), field emission scanning electron microcopy (FE-SEM) photocatalytic and antibacterial measurement. The results indicate the typical characteristic anatase form of the amino-capped TiO2 NPs with an average crystallite size of 14.9 nm. The treated cotton fabrics exhibit excellent antibacterial property and good photocatalytic degradation of methylene blue.

According to the stoichiometric ratios of Mo-10Si-7B, Mo-12Si-8.5B, Mo-14Si-9.8B, and Mo-25Si-8.5B, some new Mo-Si-B alloys doped with 0.3 wt % lanthanum (III) oxide (La2O3) were prepared via liquid-liquid (L-L) doping, mechanical alloying (MA), and hot-pressing (HP) sintering technology. The phase-composition and microstructure were investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM). The worn surfaces of the plate specimens were studied by confocal laser scanning microscopy (CLSM). Then, the tribological properties of Mo-Si-B alloy doped with sliding plate specimens of 0.3 wt % La2O3 were investigated against the Si3N4 ball specimens. The friction coefficients of Mo-Si-B alloys decreased and the wear rates of the alloys increased with test load. The high-temperature friction and wear behavior of Mo-Si-B alloy are related to the surface-oxidation and contact-deformation of the alloy at a high temperature. The low friction coefficients and the reduced wear rates are thought to be due to the formation of low friction MoO3 films. MoO3 changed the contact state of the friction pairs and behaved as lubricating films.

Published: June 2019

Superradiance describes the coherent collective radiation caused by the interaction between many emitters, mediated by a shared electromagnetic field. Recent experiments involving Bose–Einstein condensates coupled to high-finesse cavities and interacting quantum dots in condensed-matter have attracted attention to the superradiant regime as a fundamental step to create quantum technologies. Here, we consider a simplified description of superradiance that allows the evaluation of statistical moments. A correspondence with the classical birthday problem recovers the statistical moments for discrete time and an arbitrary number of emitters. In addition, the correspondence provides a way to calculate the degeneracy of the problem.

Published: June 2019

Background and Objectives: Teeth decay and plaque are complicated problems created by oral pathogens. Tecoma stans (L.) and Cassia javanica (L.) are two ornamental evergreen plants widely distributed in Egypt. These plants are traditionally used for oral hygienic purposes. This study aims to elucidate the volatile oil constituents obtained from the flowers of these plants and evaluate the antimicrobial activity of these volatile oils against specific oral pathogens in comparison to chlorhexidine. Materials and Methods: The flowers obtained from both plants were extracted by n-hexane. GC-MS spectrometry was used to identify the constituents. Minimum inhibitory concentrations (MICs) were measured using tetrazolium salt (2,3-bis[2-methyloxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide) (XTT). Results: GC-MS analysis revealed the presence of 32 and 29 compounds, representing 100% of the volatile constituents of Tecoma stans and Cassia javanica, respectively. The GC-MS analysis showed more than 60% of the volatile oil constituents are represented in both plants with different proportions. Chlorhexidine exerted stronger activity than tested plants against all microorganisms. Cassia javanica flower extract was more active against all tested microorganisms than Tecoma stans. Of note was the effect on Streptococcus mutans, which was inhibited by 100% at 12.5 and 25 µg/mL of Cassia javanica and Tecoma stans, respectively. The growth of Lactobacillus acidophilus was also completely inhibited by 25 µg/mL of the Cassia javanica extract. MIC90 and MIC were also calculated, which revealed the superiority of Cassia javanica over Tecoma stans against all tested oral pathogens. Conclusion: Cassia javanica flower volatile oils showed a potential anti-oral pathogen activity at relatively low concentrations. Also, Cassia javanica and Tecoma stans demonstrated a strong activity against tooth decay’s notorious bacteria Streptococcus mutans. Both plants can be potential substituents to chlorhexidine. Formulating the constituents of these plants in toothpastes and mouthwashes as anti-oral pathogen preparations can be an interesting future plan.

Background and objectives: Dysregulation of TGF-β signaling plays multiple roles in cancer development and progression. In the canonical TGF-β pathway, TGF-β regulates the expression of hundreds of target genes via interaction with Smads, signal transducers and transcriptional modulators. We evaluated the association of TGF-β1, Smad2, and Smad4, the key components of canonical TGFβ pathway, with clinicopathologic characteristics of urothelial bladder cancer, and assessed their prognostic value in prediction of patients’ outcome. Materials and Methods: Immunohistochemical analysis of TGF-β1, Smad2, and Smad4 expression was performed on 404 urothelial bladder cancer samples, incorporated in tissue microarrays. Expression status was correlated with clinicopathological and follow-up data. The median follow-up was 61 months. Results: High expression of TGF-β1, Smad2, and Smad4 was detected in 68.1%, 31.7% and 45.2% of the tumors, respectively. TGF-β1 overexpression was significantly associated with high tumor grade, and advanced pathologic stage (p < 0.001, respectively). Conversely, high Smad2 and Smad4 expression was linked to low tumor grade (p = 0,003, p = 0.048, respectively), and low tumor stage (p < 0.001, p = 0.003, respectively). Smad2 showed an inverse correlation with variant morphology and divergent differentiation of urothelial tumors (p = 0.014). High TGF-β1 correlated directly, while Smad2 and Smad4 correlated inversely to cancer-specific death (p = 0.043, p = 0.003, and p = 0.022, respectively). There was a strong relationship between Smad2 and Smad4 expression (p < 0.001). Survival analyses showed that high Smad2 and Smad4 expression was associated with longer overall survival (p = 0.003, p = 0.034, respectively), while in multivariate regression analysis TGF-β1 manifested as an independent predictor of poor outcome. Conclusions: Unraveling the complex roles and significance of TGF-β signaling in urothelial bladder cancer might have important implications for therapy of this disease. Assessment of TGF-β pathway status in patients with urothelial bladder cancer may provide useful prognostic information, and identify patients that could have the most benefit from therapy targeting TGF-β signaling cascade.
