Published: June 2019

Introduction. The article considers the enhancement of physical and mechanical parameters of construction mortars used for recovering and repairing of building structures of communication collectors by using low-temperature nonequilibrium plasma. The study vindicated the expediency of treatment of construction mortar raw materials with LTNP to enhance their physical and mechanical parameters. The effect of plasma modification of raw materials on Portland cement phase composition, granulometric composition of the sand and mortar properties are analysed. The influence of multiplicity of silica sand and mixing water plasma treatment on the construction mortar strength is considered.
Materials and methods. Cement-sand mortars are obtained from Portland cement of the CEM I 32.5N and CEM I 42.5N brands and silica sand with the fineness moduli of Mf = 0.32 and Mf = 0.63 and a separate fraction of less than 0.16 mm. Setting time and strength of the building mortars are defined according to GOST state standards in effect. Granulometric composition of the cement is explored by means of Analysette-22 particle size microanalyser, while ARL Optim’X spectrometer is used for studying phase composition of the cement stone, silica sand and cement-sand mortars.
Results. It is determined that the plasma treatment of Portland cement reduces the grout normal consistency by 15 to 17 % and decreases its setting time by a factor of 3 to 4. Treatment of mixing water with the nonequilibrium low-temperature plasma removes its hardness, forming additional crystallization nuclei. The plasma-treated mixing water increases the curing rate of cement-sand mortars up to 50 % at the early stages of hardening and up to 30 % on the 28th day of hardening. Using plasma-treated silica sand decreases size of its particles and results in partial transition of the crystalline structure into the amorphous one. This reduces water demand of the sand by 10 to 18 %.
Conclusions. The expedience of plasma treatment of raw materials to enhance the physical and mechanical properties of mortars is vindicated. Owing to the plasma modification of raw materials, quality and process characteristics of construction mortars are improved. The presented method of the plasma treatment of raw materials used to prepare the construction mortars is characterized with high degree of efficiency and convenience of application.
Validity of geophysical parameters in the mudflow cadastre of the south of Russia
Authors: Anakhayev Koshkinbai N. 
Published: June 2019

Introduction. When evaluating mudflow danger level and developing hydroengineering anti-mudflow measures, a great meaning is obtained by mudflow basin cadastres that are widely used as reference sources by water-economic project establishments, scientists, specialists of federal and local authorities. The cadastres influence the made decisions on development of the anti-mudflow measures and protective hydroengineering facilities, since the cadastres include basic dedicated data on mudflow basin locations, geophysical (geomorphometric, hydrological) characteristic and expected mudflow parameters.
Materials and methods. The article uses known and proven methods of analysis of mudflow basin cadastres. The analytical methods are based on a comparative assessment of the presented results with basic geophysical data of primary sources (cadastres published earlier) and on-site investigations as well as compliance of the suggested empirical formulae on determination of mudflow carrying out volumes and indicators of territorial mudflow striking with mathematical and physical conditions of development of the real mudflow phenomena.
Results. Critical analysis of the contents of the Cadastre of Mudflow Danger of the South of the European Part of Russia published in 2015 allows revealing multiple distortions and substitutions of basic geophysical data of mudflow basins. There is an inaccuracy (up to 3,000 to 4,000 % and even higher) of the empirical formulae used in the cadastre for determination of volumes of modflow carrying out. The analysis reveals a hydrogeographical error connected with unfounded substitution of the concept “river length” with the value of the “total length of the main course and all its inflows” that multiply overrates the calculated riverbed length and multiply underrates value of a riverbed bias. Also the study emphasizes unacceptability of definition of the mudflow danger territory by the principle “the water-collecting area of the mudflow course is totally mudflow-threatened" owing to which the absolutely safe natural landscapes are unreasonably declared mudflow-threatened territories.
Conclusions. The stated analysis shows a discrepancy of the considered cadastre to the status of scientific and research work. In this connection, the cadastre cannot be recommended for use both in scientific researches and in practical ones. Recommendations on improvement of the mudflow basin cadastres are provided.

Religião e defesa da paz: poder, justiça e responsabilidade comum / Religion supporting peace: power, justice and common responsibility
Authors: Barros Douglas Ferreira 
Published: June 2019

Este artigo tem por objetivo debater a relação entre religião e a promoção da paz, à luz de algumas interpretações que, embora distantes do enquadramento estabelecido por Agostinho, ainda exploram aspectos por ele trabalhados. Assim, pretende-se mostrar como as abordagens da paz propostas por Marsílio de Pádua e Hobbes inovam em relação ao filósofo cristão. Pretende-se também apontar que, desde o fim da modernidade, com Kant, até a contemporaneidade, o debate sobre o tema transita da tese da obediência para a de que a paz pressupõe o estabelecimento de novas relações de domínio sobre os homens e destes entre si e com o poder. Como metodologia, utiliza-se a interpretação de textos desses filósofos e de alguns parágrafos da Doutrina Social da Igreja. Concluindo, o estudo propõe que a defesa da paz demanda que ela seja pensada prioritariamente segundo o registro das relações entre os homens, e não necessariamente sob o viés exclusivo da obediência ou da submissão a poderes políticos.

Mangrove existence is necessary to protect coastal. One method that can be used to keep mangrove existence were using satellite imagery monitoring. The number of bands in the imagery led to the selection for the RGB composite bands was difficult because a lot of combinations to try. One technique that can be done to get the best RGB combination of an object is to use Optimum Index Factor (OIF). OIF is a statistical technique for selecting three combinations of imagery bands to visualize the image display to the fullest. It is based on the value of total variance and the correlation coefficient between the bands. Landsat 8 has 7 bands with 30 m resolution, one panchromatic band with 15 m resolution, and two bands with 100 m resolution. The purpose of this study was to detect true mangrove using three bands from OIF value of Landsat 8. The results of the processing from 6 bands (2-7), obtained 20 bands combinations with the highest value of OIF is 0,168, ie, bands 2-56 (Blue, NIR, SWIR-1). Based on the combination, the next step was unsupervised classification process for true mangrove identification (Rizhopora, Brugueira, Avicennia, Soneratia). The best classification using band combination 2-7 with true mangrove reached 4.041 ha.

Published: June 2019

Abstract

OBJECTIVE
To evaluate and quantify the kinematic behavior of canine mandibles before and after bilateral rostral or unilateral segmental mandibulectomy as well as after mandibular reconstruction with a locking reconstruction plate in ex vivo conditions.

SAMPLE
Head specimens from cadavers of 16 dogs (range in body weight, 30 to 35 kg).

PROCEDURE
Specimens were assigned to undergo unilateral segmental (n = 8) or bilateral rostral (8) mandibulectomy and then mandibular reconstruction by internal fixation with locking plates. Kinematic markers were attached to each specimen in a custom-built load frame. Markers were tracked in 3-D space during standardized loading conditions, and mandibular motions were quantified. Differences in mandibular range of motion among 3 experimental conditions (before mandibulectomy [ie, with mandibles intact], after mandibulectomy, and after reconstruction) were assessed by means of repeated-measures ANOVA.

RESULTS
Both unilateral segmental and bilateral rostral mandibulectomy resulted in significantly greater mandibular motion and instability, compared with results for intact mandibles. No significant differences in motion were detected between mandibles reconstructed after unilateral segmental mandibulectomy and intact mandibles. Similarly, the motion of mandibles reconstructed after rostral mandibulectomy was no different from that of intact mandibles, except in the lateral direction.

CONCLUSIONS AND CLINICAL RELEVANCE
Mandibular kinematics in head specimens from canine cadavers were significantly altered after unilateral segmental and bilateral rostral mandibulectomy. These alterations were corrected after mandibular reconstruction with locking reconstruction plates. Findings reinforced the clinical observations of the beneficial effect of reconstruction on mandibular function and the need for reconstructive surgery after mandibulectomy in dogs.

Published: June 2019

Abstract

OBJECTIVE
To evaluate effects of poly(ADP-ribose) polymerase-1 (PARP1) inhibitors on the production of tumor necrosis factor-α (TNF-α) by interferon-γ (IFN-γ)– and lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMCs) of horses as an in vitro model of inflammation in horses.

SAMPLE
1,440 samples of PBMCs from 6 healthy research horses.

PROCEDURES
From heparinized whole blood samples, PBMC cultures were obtained. An initial dose-response trial on 48 PBMC samples from 2 horses (24 samples each) was used to determine concentrations of IFN-γ and LPS for use as low- and high-level stimulation concentrations. Seventy-two PBMC samples from 6 horses were assigned equally to 1 of 4 PARP1 inhibition categories: no PARP1 inhibitor (PARP1 inhibition control); 2-((R)-2-methylpyrrolidin-2-yl)-1H-benzimidazole-4-carbozamide dihydrochloride (ABT888);4-(3-(1-(cyclopropanecarbonyl)piperazine-4-carbonyl)-4-fluorobenzyl)phthalazin-1(2H)-one (AZD2281); or N-(6-oxo-5,6-dihydrophenanthridin-2-yl) -N,N-dimethylacetamide hydrochloride (PJ34). Samples of PBMCs from each horse and each PARP1 inhibition category were then assigned to 1 of 3 levels of IFN-γ and LPS stimulation: none (control), low stimulation, or high stimulation. After a 24-hour incubation period, a TNF-α ELISA was used to measure TNF-α concentration in the supernatant. Results were compared across treatments and for each horse. Data were analyzed with repeated-measures ANOVA.

RESULTS
Median TNF-α concentration was significantly lower for PJ34-treated, high-level stimulated PBMCs than for PARP1 inhibition control, high-level stimulated PBMCs; however, no other meaningful differences in TNF-α concentration were detected among the inhibition and stimulation combinations.

CONCLUSIONS AND CLINICAL RELEVANCE
Findings suggested that PJ34 PARP1 inhibition may reduce TNF-α production in horses, a potential benefit in reducing inflammation and endotoxin-induced damage in horses.

Published: June 2019

Abstract

OBJECTIVE
To determine the pharmacokinetics of pentoxifylline (PTX) and its 5-hydroxyhexyl metabolite (M-I) after IV administration of increasing doses of PTX to sheep.

ANIMALS
6 healthy adult Merino sheep.

PROCEDURES
Each sheep received 10-, 20-, and 40-mg/kg doses of PTX, IV, with a 15-day washout period between doses. Blood samples were collected before and at predetermined times after administration of each dose to determine plasma PTX and M-I concentrations by high-performance liquid chromatography. Pharmacokinetic parameters for PTX and M-I were estimated by noncompartmental analysis.

RESULTS
No adverse effects were observed after administration of the 10- and 20-mg/kg doses. Following administration of the 40-mg/kg dose, all sheep developed tachycardia and hypersalivation and appeared agitated for approximately 4 hours. Plasma PTX concentrations considered therapeutic in other species were achieved in all sheep after administration of all 3 doses. Pharmacokinetic parameters for PTX and M-I varied in a dose-dependent linear manner. For PTX, the mean area under the concentration-time curve (AUC), elimination half-life, and volume of distribution increased with dose and ranged from 15.67 to 94.66 h·μg/mL, 0.68 to 0.91 hours, and 0.55 to 0.66 L/kg, respectively, whereas clearance decreased with dose and ranged from 0.42 to 0.64 L/h/kg. The mean ratio of the AUC for M-I to AUC for PTX ranged from 0.38 to 0.46.

CONCLUSIONS AND CLINICAL RELEVANCE
Results indicated that pharmacokinetic parameters for PTX and M-I varied in a dose-dependent linear manner in healthy sheep. Further studies are warranted to determine the therapeutic threshold and optimal dosage for PTX in sheep.
Core-in-cup/liquisol dual tackling effect on azelnidipine buccoadhesive tablet micromeritics, in vitro release, and mucoadhesive strength
Authors: Rashad Amira A. , El-Helaly Sara Nageeb , Abd El Rehim Randa T. , El-Gazayerly Omaima N. 
Published: June 2019

Abstract
Reduced bioavailability of azelnidipine is related to its poor aqueous solubility and extensive first-pass metabolism, which hinder its efficacy. These problems were addressed by implementing (1) a liquisol technique for promoting the dissolution rate in a controlled-release manner and (2) a core-in-cup bucco-adhesive drug delivery system as an alternative to the oral route. A 33 factorial design was used to study the effects of polymer type (sodium carboxymethyl cellulose (CMC Na), chitosan, or Carbomer P940) concentration (5, 10 or 15 %) and preparation technique (simple mix, liquisol or wet granulation) on the dissolution and mucoadhesion of core-in-cup azelnidipine buccoadhesive tablets. Tablet micromeritics, swelling index, mucoadhesive strength and in vitro release were characterized. Statistical analyses of these factors show ed significant effects on the studied responses, where F#16 prepared by the liquisol technique and containing 15 % CMC Na was chosen with an overall desirability of 0.953.

Published: June 2019

Abstract

Lamium album and Lamium purpureum are species belonging to the genus Lamium. Aerial parts of the two species and roots of Lamium album have applications in human and veterinary traditional medicine. Haemostatic properties of butanolic extracts of Lamium species were investigated by two experimental models in Wistar rats: haemostatic test by tail bleeding time determination and acenocoumarolcarrageenan test. Results of the haemostatic test by tail bleeding determination demonstrated haemostatic activity of both extracts. In the acenocoumarol-carrageenan test, only the Lamium album extract showed haemostatic activity, comparable to that of vitamin K. Based on the qualitative chemical data on iridoid glycosides (HPTLC), 8-acetylshanzhiside methyl ester might be assumed to be responsible for haemostatic activity. Based on the acute toxicity test, none of the extracts showed toxicity.
Sacred Landscapes in Galicia: Small Religious Architecture and Symbolism
Authors: Calaza-Martínez Pedro , Freire-González Nuria , Blanco-Pampín Camilo 
Published: June 2019

Abstract
Cultural landscapes are multi-layered entities that constantly endure changes and transformations, especially in Europe due to its ancient history and anthropized nature, which reveals itself not only in physical elements, but also through immaterial heritage. This paper aims to analyse the connection between sacred landscapes, small religious architecture and folklore, focusing on the origin and transformations of several places in Galicia (northwest of Spain). Galicia is defined by its rich flora and fauna, a management of its land based on smallholding and the social idiosyncrasy of its people, defined by strong symbolism and the religious tradition that is reflected in a great amount of small sacred architecture. All this provide a paradigmatic territory for this research, allowing an approach to the case studies from the point of view of landscape architecture, assessing the small sacred architecture elements, their background, symbolism and associated vegetation. It is worth mentioning that, although vegetation had a very strong meaning and symbolism in the sacred history of Galicia, nowadays it only appears in 26% of the analysed case studies.
Small Sacral Architecture and Its Greenery in Lower Spiš Region in Slovakia
Authors: Halajová Denisa , Tóth Attila , Halaj Peter 
Published: June 2019

Abstract
Small sacral structures are significant elements of Spiš cultural landscapes (North-East Slovakia). This paper presents results of the field mapping of small roadside sacral objects and their greenery along a 66-kilometre long road section connecting North and South of Lower Spiš and the municipalities of Levoča, Spišská Nová Ves, Hnilčík, Mníšek nad Hnilcom, Smolník, and Úhorná. This road was an old trade route and has an important historical legacy in Lower Spiš – a traditional mining cultural landscape with a characteristic hilly topography, wide forest landscapes and rich mining history. The presented mapping was conducted within the research project VEGA 1/0371/18 “SacralArch: Preservation of the Historical Legacy and Architectural Diversity of Small Sacral Structures in Cultural Landscapes of Slovakia“, based on the methodology elaborated by Tóth (2018), which includes localisation, spatial context, technical or health condition and an overall description of the sacral element and the woody plants in its direct surroundings. In total, 13 small roadside sacral objects were mapped, while the most prevailing elements are crosses. The most common cross type is wooden cross without pedestal. The oldest and aesthetically most valuable elements are metal crosses on stone pedestals, made of travertine. The most valuable element is a registered cultural monument – a Baroque roadside chapel of St. John of Nepomuk from 1726 in Smolník. Woody plants accompany only roadside crosses in the study area. The oldest and most significant in terms of landscape value are individuals of small-leaved linden trees (Tilia cordata Mill).
