Authors: Cartolin Ximena , Herrera Patricia , León Daphne , Falcón Néstor
Published: December 2020

El objetivo del estudio fue determinar las percepciones acerca del impacto emocional que produce la pérdida o muerte del animal de compañía en la vida de quienes fueron sus propietarios. Para ello se diseñó un estudio observacional descriptivo a base de entrevistas. Se realizaron 100 encuestas y se encontró que el 87 y 9% de los encuestados tuvieron perros y gatos, respectivamente. La edad promedio de adquirido fue 0.8 y 0.2, y tiempo promedio de tenencia de 7.6 y 2.6 años, para perros y gatos, respectivamente. Las razones predominantes de la tenencia fueron gusto hacia los animales (39%) y la compañía que otorgaban (35%). Las formas de obtención frecuentes fueron el regalo (52%), compra (27%) y adopción (19%). La mayoría valoró como muy importante (62%) e importante (34%) su tenencia. Los entrevistados manifestaron sentir hacia su animal sentimientos de amor/cariño (43%), alegría/felicidad (27%) y ternura (17%). La reciprocidad del animal, según los encuestados, principalmente se expresaba con movida de cola (22%), lametazo (15%) y seguimiento al dueño (11%). El principal benefició percibido fue la compañía (77%). La mayoría lo consideró parte o miembro de la familia (55%). El juego (96.3%) y paseo (93%) eran las actividades que realizaban diariamente. Las principales causas de pérdida fueron enfermedad (37%), vejez (22%) y desaparición (15%). La sensación inicial causada después de la pérdida del animal de compañía fue tristeza/pena/nostalgia (62%). El 86% comentó que la pérdida alteró poco su vida, 6% mucho y 8% no le afectó. La sensación respecto al animal de compañía perdido al momento de la encuesta fue de tristeza (31%) y buen recuerdo (22%). La tenencia de un nuevo animal buscó suplir a la pérdida producida. La pérdida de un animal de compañía debe direccionarse adecuadamente para contener el impacto emocional sobre los propietarios.

El objetivo del presente estudio fue evaluar el comportamiento productivo de pollos de engorde y las características morfométricas e indicadores de mineralización de las tibias como efecto de la inclusión de cinco fuentes de fosfato inorgánico comerciales en la dieta. Se utilizaron 300 pollos BB macho de la Línea Cobb 500, distribuidos al azar en seis tratamientos con 10 repeticiones por tratamiento y cinco aves por repetición. Las aves fueron alimentadas por 21 días con las siguientes dietas: T1, dieta basal + fosfato monosódico grado alimenticio (MNaP); T2, dieta basal + fosfato dicálcico (DCP); T3, dieta basal + fosfato monodicálcico 1 (MDCP 1); T4, dieta basal + fosfato monodicálcico 2 (MDCP 2); T5: dieta basal + fosfato monocálcico 1 (MCP 1); T6, dieta basal + fosfato monocálcico 2 (MCP 2). Se registraron variables productivas: peso vivo, ganancia de peso, consumo de alimento y conversión alimenticia. Las aves fueron sacrificadas a los 21 días y se retiraron las tibias para determinar su morfometría (peso, largo, diámetro de diáfisis y volumen) e indicadores de mineralización ósea (densidad, índice de Seedor, índice de robusticidad y resistencia de tibia). Adicionalmente, se determinaron los porcentajes de cenizas, calcio y fósforo en la tibia. Los tratamientos no tuvieron influencia significativa sobre la respuesta productiva de las aves, así como en la morfometría ósea e indicadores de mineralización de la tibia. Sin embargo, el porcentaje de P a nivel de la tibia fue afectado (p<0.05) por la fuente de fosfato utilizado, siendo T2 (DCP) el que presentó mayor porcentaje. Se concluye que la fuente de fosfato no afectó el comportamiento productivo, pero que el DCP presentó una mayor retención de fósforo a en la tibia.

Published: December 2020

El estudio tuvo como objetivo evaluar la precisión y exactitud de equipos que determinan la calidad de fibras de ovinos. Los equipos utilizados (total = 15) fueron Sirolan Laserscan, OFDA 2000, Minifiber EC y Fiber EC, pertenecientes a nueve laboratorios de Perú (n=7) y Argentina (n=2). Se determinaron las medias del diámetro medio de fibra (MDF) con relación a los límites de tolerancia determinados por las normas IWTO 12 e IWTO 47, utilizándose muestras de fibras con diámetros conocidos. La exactitud se determinó a partir del promedio obtenido de las submuestras menos el valor real de las muestras y la precisión fue evaluada mediante la desviación estándar de las repeticiones. Se utilizó el método de comparaciones múltiples de Dunnett para la precisión y la exactitud. Los resultados demostraron que los equipos codificados como B y C de los laboratorios 4 y 8 fueron los más exactos, mientras que los equipos B y D de los laboratorios 5 y 8 resultaron ser los más precisos. Asimismo, seis de los nueve laboratorios tuvieron equipos que determinaron la MDF dentro de los límites de tolerancia acorde a las normas IWTO 12e IWTO 47, por lo que se recomienda implementar pruebas inter-laboratorios y de equipos que evalúan fibras a nivel nacional.

Published: December 2020

El objetivo de esta investigación fue evaluar el uso de diferentes diluyentes para la refrigeración de semen de conejo y su efecto sobre la calidad espermática. Se utilizaron 30 muestras de semen de 10 conejos (Oryctolagus cuniculus) sexualmente maduros. Cada muestra se diluyó separadamente en proporción 1:10 en cuatro diluyentes, compuestos por leche descremada y azucares (T1); dextrosa, citrato sódico y acetato potásico (T2); caseinatos de sodio, fosfatos y azúcares (T3); y tris-ácido cítrico y yema de huevo (T4). El semen se mantuvo a 16 °C durante 72 horas. Al momento de la dilución y cada 24 horas se evaluó la movilidad total (MT), la movilidad progresiva (MP) y la cinética espermática con el sistema Sperm Class Analizer®, y la viabilidad y la morfología mediante la tinción con eosina-nigrosina. El análisis estadístico se realizó mediante modelos mixtos y la comparación de medias por la prueba de Duncan. Al momento de la dilución (0 h), se observó una MT inferior para T2 y T4 en comparación con T1 y T3 (p<0.05). Este mismo efecto se observó a las 24 h de refrigeración, mientras a las 48 h la MT fue inferior para T2, respecto a T1, T3 y T4 (p<0.05). La MP fue igualmente superior para T1 y T3 a las 0, 24 y 48 h (p<0.05). Se halló un descenso en la morfología normal a las 72 h para T4 (p<0.05). Se observó una mayor conservación de la viabilidad en el tiempo para T1 y T3 (p<0.05). Se concluye que los diluyentes compuestos por leche descremada o caseinatos con azucares protegen de forma más eficiente los espermatozoides de conejo conservados mediante refrigeración.

El experimento fue conducido para determinar los coeficientes de digestibilidad y la energía digestible de la harina de kudzu (Pueraria phaseoloides) en cuyes. Se utilizaron 10 cuyes machos de 12 semanas y 828 g de peso promedio, colocados en jaulas metabólicas. Cinco animales fueron alimentados con la dieta basal (subproducto de trigo) y los otros cinco con la dieta experimental (60% subproducto de trigo y 40% harina de kudzu). Para estas determinaciones se utilizó el método indirecto, teniendo como alimento basal al subproducto de trigo, cuyos coeficientes de digestibilidad se determinaron por el método directo. Se tuvo una fase pre-experimental de 14 días para la adaptación de los cuyes a las instalaciones y la nueva dieta. La fase experimental fue de seis días, en la cual se realizó la colección de heces. En ambas fases se midió diariamente el consumo de alimento. Los coeficientes de digestibilidad aparente obtenidos fueron: 42.90% de materia seca, 40.57% de materia orgánica, 81.07% de proteína cruda, 68.86% de extracto etéreo, 30.77% de fibra cruda, 30.55% de extracto libre de nitrógeno y 74.18% de ceniza. El valor de la energía digestible determinado por diferencia fue de 1.98 Mcal/kg de materia seca.

Ingenio e innovación. Los atrapanieblas como objetos-fluidos
Authors: Yrivarren Joaquín
Published: December 2020

En este ensayo ponemos en discusión la noción de ‘prospectiva’ y los dilemas de imaginar el futuro para tomar decisiones hoy. Para muchos la vida cotidiana es experimentada dentro del estilo del corto plazo (‘acontecimientos’), mientras la prospectiva apunta a un horizonte abierto y múltiple para acciones y proyectos (‘escenarios’). El problema es precisamente encontrar un buen ensamblaje entre acontecimientos y escenarios, o también, entre el ingenio y la innovación. Nuestra propuesta, ampliamente, es reconocer los escenarios (mundos posibles y deseados) en los acontecimientos y asentar la innovación en los recursos y aprendizajes introducidos por el ingenio. Empíricamente, ello conlleva analizar ‘datos portadores de (poco) futuro’ y (pluri)tendecias. Este ensayo se desenvuelve en torno al caso de los atrapanieblas en el distrito de Villa María del Triunfo (Lima), describiendo el tránsito desde su experimentación cerrada, su definición como ‘objeto-fluido’ y su incorporación en un proyecto urbano más amplio.

¡Y llegó el bicentenario! Ciudad, clase social y vivienda en Lima (1821-2020)
Authors: Calderón Cockburn Julio
Published: December 2020

Este artículo intenta un balance de la ciudad de Lima en su patrón de crecimiento espacial y la atención del problema de la vivienda durante el periodo republicano (1821-2020), prestando atención al proceso de desigualdad generado según las diversas clases sociales. Aborda tres periodos: 1821-1920, caracterizado por el abierto predominio del mercado en la producción de vivienda, 1921-1989 en que se definen los ejes de crecimiento de la ciudad de Lima, se establecen los patrones de segregación social y espacial, y los planteamientos del urbanismo moderno ceden paso a una visión “realista” que acepta la barriada como la “solución” a la vivienda. Finalmente, el periodo 1990-2020, representa la adopción de políticas neoliberales y un abandono, relativo, del papel del Estado, con consecuencias del fomento mayor de la informalidad y el empeoramiento de la atención de la vivienda.

Corylus avellana pollen and catkins characterization on genotypes from selected localities of West Slovakia
Authors: Nikolaieva Nataliia , Nôžková Janka , Gažo Ján
Published: December 2020

Hazelnut (Corylus avellana L.) has unusual ability to adapt to extreme conditions and is widely spread throughout Slovakia. Under the influence of various environmental factors shape and size of habitus, leaves, fruits, and catkins change. That is the reason why hazelnut became the subject of research in many countries. The important stage in the study of hazelnut plants was the use for cultivation purposes. The traits from cultivated genotypes are transported also on wild genotypes. Genetic diversity of hazelnuts confirmed survival adaptability. The application research and experimental development in conservation of environment and agriculture are interconnected by different approaches. The biological objectives are native organisms, and they are constantly in inseparable unity with the environment, but environment conditions are unstable. Organisms adapt to new living conditions through the activation the synthesis of nucleic acids and proteins. This factor influences on variability evaluation of genetic resources. In our study we tried to find the most distinguishing sample by combined empiric knowledge with innovative methods for morphological characterization. We worked with pollen grains and catkins (male inflorescences). We proposed to combine the results of different experimental works for identifying the suitable genotypes for further using.

OBJECTIVES:

We aimed to describe the clinical and laboratory characteristics of febrile infants ≤60 days old with positive urinalysis results and invasive bacterial infections (IBI).

METHODS:

We performed a planned secondary analysis of a retrospective cohort study of febrile infants ≤60 days old with IBI who presented to 11 emergency departments from July 1, 2011, to June 30, 2016. For this subanalysis, we included infants with IBI and positive urinalysis results. We analyzed the sensitivity of high-risk past medical history (PMH) (prematurity, chronic medical condition, or recent antimicrobial receipt), ill appearance, and/or abnormal white blood cell (WBC) count (<5000 or >15 000 cells/μL) for identification of IBI.

RESULTS:

Of 148 febrile infants with positive urinalysis results and IBI, 134 (90.5%) had bacteremia without meningitis and 14 (9.5%) had bacterial meningitis (11 with concomitant bacteremia). Thirty-five infants (23.6%) with positive urinalysis results and IBI did not have urinary tract infections. The presence of high-risk PMH, ill appearance, and/or abnormal WBC count had a sensitivity of 53.4% (95% confidence interval: 45.0–61.6) for identification of IBI. Of the 14 infants with positive urinalysis results and concomitant bacterial meningitis, 7 were 29 to 60 days old. Six of these 7 infants were ill-appearing or had an abnormal WBC count. The other infant had bacteremia with cerebrospinal fluid pleocytosis after antimicrobial pretreatment and was treated for meningitis.

CONCLUSIONS:

The sensitivity of high-risk PMH, ill appearance, and/or abnormal WBC count is suboptimal for identifying febrile infants with positive urinalysis results at low risk for IBI. Most infants with positive urinalysis results and bacterial meningitis are ≤28 days old, ill-appearing, or have an abnormal WBC count.

Authors: Ganbarov Fuad , Alieva Gunay , Babazade Isgender
Published: December 2020

The dependence of the Azerbaijani economy on oil makes urgent the issue of diversifying the economy to increase its competitiveness.  This, in turn, necessitates the formation of techniques to qualitatively assess the effectiveness of diversification to alternative, namely non-oil exports. This study aims to develop an econometric model to assess the impact of non-oil export diversification on Azerbaijan's economic development. Based on the literature analysis and using hierarchy analysis by T. Saaty, a list of indicators has been proposed to assess the diversification of non-oil exports. The opinions of 30 experts were used to prioritize the indicators. An integral coefficient of diversification of non-oil exports was modelled based on an additive convolution of diversification indicators, taking into account the coefficients of their significance and expert assessments.  The research results can serve as a suggestion as to the formation of an effective strategy for the modernization of the country's economy.

Published: December 2020

Bogor Botanic Gardens is one of the outstanding green areas in Bogor City. Thousands of plant species are growing and providing suitable habitats and feed for various pollinators, such as butterflies, bees, and wasps. A well-designed pollination garden will benefit the pollinators and also create an educational facility for the community. This study aimed to select and characterize species of flowering plants that effectively attract pollinators, particularly Lepidoptera and Hymenoptera, in the pollination garden candidate area. The observa-tion had been carried out on 12 ornamental plant species: Pennisetum purpureum, Cosmos sp., Pachystachys lutea, Cuphea hyssopifolia, Orthosiphon aristatus, Lantana camara, Citrus aurantifolia, Buddleja davidii, Ixora javanica, Nerium oleander, Hibiscus rosa-sinensis, and Aglaia odorata. The method for observing pollinators was a standard walking method. Pollinator photos, its number, its visit time, and the plants it visited were recorded. A total of 23 species of Lepidoptera (20 species from 4 families and 3 species were unidentified) and 9 species of Hymenoptera (4 families) were found in the area with the best obser-vation time at 08.30-09.30 (GMT+7). The most visited plants by pollinators were Cuphea hyssopifolia, Lantana camara and Orthosiphon aristatus. Lepidoptera and Hymenoptera preferred blue-purple and bright-orange-yellow flowers. In addition, the flower characters that might influence pollinator visits are also described. The result would be an essential recommendation for plant selection, landscape design, and construction of the pollination garden in Bogor Botanic Gardens.

Sarcoidosis is an inflammatory disease of unknown etiology with damage to the lungs and other organs characterized by development of necrosis-free epithelioid cell granulomas. Granulomatous inflammation characterized by the activation of different immune systems cells, in particular T lymphocytes, and the cytokines production. Our study was aimed at investigating the characteristics of the cytokine profile of blood plasma in patients with sarcoidosis. We studied peripheral blood plasma samples of patients with sarcoidosis (n = 52). The control blood samples were taken from healthy volunteers (n = 22). The level of 46 cytokines (pg/ml) was determined, as follows: IL-1α, IL-1β, IL-2, IL-3, IL-4, IL-5, IL- 6, IL-7, IL-9, IL-12 (p40), IL-12 (p70), IL-13, IL-15, IL-17A, IFNα2, IFNγ, TNFα, TNFβ, IL- 1ra, IL-10, EGF, FGF-2, Flt3 Ligand, G-CSF, GM-CSF, PDGF-AA, PDGF-AB / BB, TGFα, VEGF-A, sCD40L, CCL2, CCL3, CCL4, CCL5, CCL7, CCL11, CCL17, CCL20, CCL22, CXCL1, CXCL8, CXCL9, CXCL10, CXCL11, CXCL13, CX3CL1. Significantly higher levels of interleukins and some proinflammatory cytokines were found in the patients with sarcoidosis, i.e., IL-3, 0.70 vs 0.20, p = 0.003; IL-4, 14.37 vs 3.15, p = 0.009; IL-5, 1.06 vs 0.89, p < 0.001; IL-12 (p70), 1.27 vs 0.56, p = 0.028; IL-17A, 1.48 vs 0.43, p < 0.001; IFNα2, 41.79 vs 25.04, p = 0.003; IFNγ, 4.13 vs 1.14, p < 0.001; TNFα, 21.67 vs 6.70, p < 0.001; anti-inflammatory cytokine IL-10, 1.03 vs 0.45, p = 0.019; growth factors: FGF-2, 40.08 vs 30.58, p = 0.008, G-CSF, 24.18 vs 8.21, p = 0.006, and VEGF-A, 42.52 vs 26.76, p = 0.048; chemokines: CCL3, 3.86 vs 1.33, p < 0,001; CCL17, 78.24 vs 26.24, p < 0.001; CCL20, 7.19 vs 5.64, p = 0.021; CCL22, 660.60 vs 405.00, p < 0,001; CXCL9, 4013 vs 1142, p < 0,001; CXCL10, 565.90 vs 196.60, p < 0.001; CXCL11, 230.20 vs 121.10, p = 0.018; CX3CL1, 56.99 vs 5.16, p < 0.001. Peripheral blood chemokine CCL11 levels were significantly lower in patients compared to the group of healthy volunteers: 77.58 vs 124.70, p = 0.022. The features of the cytokine profile in patients with sarcoidosis may indicate their important role in the processes of formation and outcomes of granulomas. These issues require an additional detailed study, comparison with phenotypes, differential course and outcomes of the disease.

Published: November 2020

Significant damage to the auxiliary spillway at Toddbrook Reservoir resulted in the evacuation of 1500 residents from Whaley Bridge for a period of 7 days. During this period, emergency works were carried out to minimise the risk of the embankment failing and allow residents to return to their homes and livelihoods. Since the emergency works, the Canal & River Trust have completed an interim project which includes a number of measures to improve the resilience of the reservoir until the spillway is replaced. This paper presents the site observations made during the construction of the in situ concrete cut-off trench located along the crest of the auxiliary spillway.

Objective : The ideal controlled ovarian stimulation protocol for patients with poor ovarian response (POR) is not clear yet, and is the subject of many studies. Aromatase inhibitors have been introduced as a new treatment modality in controlled ovarian stimulation as they were found to elevate follicular sensitivity to gonadotropins(Gn). The aim of this study was to evaluate whether it is possible to reduce the required Gn dose by adding letrozole to the treatment without compromising success.
Material and Methods: Patients who underwent in vitro fertilization treatment between 2014 and 2015 in our department and who were classified as poor responder patients according to Bologna criteria were recruited and randomized. In the first group, 33 patients were treated with 150 IU Gn in combination with letrozole 5 mg /day for the first five days of the stimulation. In the second group, 27 patients were treated with 300 IU Gn.
Results: Amoung the groups there were no statistically significant difference in duration of ovulation stimulation, duration of antagonist use, number of retrieved oocytes, number of transferred embryos, implantation, cycle cancelation, chemical, clinical and ongoing pregnancy rates (all p>0.05). Gn use was significantly higher in 300 IU Gn alone group compared to 150 IU Gn in combination with letrozole group (1354 ± 468 IU versus 2555 ± 725 IU, p<0.05).
Conclusion: The addition of letrozole yields comparable pregnancy outcomes with significantly low doses of Gn, so may be regarded as an effective adjuvant agent in POR patients.

ABSTRACT Sixteen of the world's hottest years since 1860 were in the last 17 years. Greenhouse gases cause global warming and climate change (CC). Climate change puts agriculture at a crossroads. The industry must adapt in order to feed a global population projected to reach 9.8 billion by 2050 and 11.2 billion by 2100. Adapting to CC requires agriculturalists at all levels to devise appropriate mitigation strategies. Business cannot be as usual. Climate change adds complexity to agriculture. To remain relevant, agricultural practitioners must be climate-smart (CS) in order to continue producing adequate, affordable, nutritious and safe food and fibre. Furthermore, agriculture is a business. It involves inputs, outputs, profit, loss, and is tied to the economic factors of production, land, labour, capital, and entrepreneurship. Therefore, the astute Agricultural Extension Professional/s (AEP/s) must be conversant not only with scientific and technical aspects of agriculture, its business and art, but also with emerging CC issues. The AEP must have relevant hard and soft skills that enable him/her to assist farmers adapt. This paper discusses the essential characteristics of a CS and commercially astute AEP in changing climate. Keywords: Extension agent, Climate change, Skills
Influence of farmers' knowledge of climate change on production of citrus and tomato in Nigeria

ABSTRACT Production is the basis of value-chain which is a key factor in Agricultural Transformation Agenda (ATA) in Nigeria. Thus, for successful production of horticultural crops the importance of climate cannot be overemphasized. Therefore, in this era of climate change there is the need to study farmers' knowledge of climate change and their production level. The study was carried out in Nigeria. Multistage sampling technique was used to arrive at a study population of 441 tomato and citrus farmers. Data were collected using Focus Group Discussions (FGDs), structured interview schedule and secondary data (FAOSTAT). It was analyzed using descriptive statistics (frequencies, percentage and pie charts) and inferential statistics (Pearson Product Moment Correlation). There existed no significant relationship between knowledge level of respondents and change in production of both crops. The reason for this could be that no matter what the level of knowledge one may have on the subject of climate change it does not have anything to do with production, adaptation strategies is the key. Citrus and tomato farmers' adaptation strategies to climate change includes among others crop management, use of varieties resistant to pests and diseases, altering the timing or location of cropping activities, different planting dates and shortened length of growing period. In conclusion climate change has affected the production of horticultural crops therefore for ATA to have a good footing there is the need to focus on the adaptation strategies that can combat the effect of climatic changes.

Published: November 2020

Standard source apportionment techniques for atmospheric particulate (PM) collected near opencast coal mines provide less accurate results, as the inorganic mineral components in the overburden and at adjacent residential locations are similar. This study explores the use of the stable carbon (C) and nitrogen (N) isotope ratios (13C/12C and 15N/14N) and thermal optical methods to differentiate sources of carbonaceous material in the atmospheric PM samples from the opencast coal mines and adjacent communities.  Both techniques allow a clear distinction between atmospheric PM samples from the opencast coal mines and communities to be made, although distinguishing between the contributions of coal combustion, liquid fuel combustion and the domestic use of biomass for requires further analysis.

The problem with vibration disturbance of the reservoir of ellipsoidal shape, partially filled with a liquid, is under consideration. For the construction of the model, we use the before developed method, based on the use of non-Cartesian parametrization of the domain, occupied by a liquid. And the method of the auxiliary domain for satisfying boundary conditions on tank walls above the unperturbed free surface of a liquid, where the liquid can pass in its perturbed motion. The liquid is considered as ideal incompressible. The mathematical model of the system is constructed based on the variational formulation of the problem in the form of the Hamilton–Ostrogradskiy principle. The motion of a liquid free surface is given in the form of decomposition with respect to normal modes of oscillations. Amplitude parameters of oscillations of a liquid free surface together with parameters of the translational motion of the reservoir form a complete independent system of parameters, for which the resolving system of ordinary differential equations is constructed. The constructed model includes nonlinear properties of the system and corresponds to the model of the combined motion of the liquid with the reservoir. According to its structure, the model has considerable similarities with the case of the cylindrical reservoir. The practical implementation of the method is done for vibration disturbance of the system motion in the horizontal plane for the case of extended and compressed ellipsoidal reservoirs. The analysis of the character of manifestation of the dynamical behavior of the system in different ranges of frequencies of motion disturbance shows that mainly this system behaves as a system with the soft type of nonlinearities. The system output to the steady mode of oscillations is not observed. Modulation of oscillations of a liquid free surface is considerably manifested for most modes. Increased attention is paid to the study of regularities of variation of a period of the oscillation modulation. It was ascertained that due to compression of the spectrum of liquid oscillations with the increase of the wavenumber, the simultaneous considerable effect of several frequencies is manifested in the system reservoir–liquid, which leads to complex modulation envelope lines.

The involvement of free radicals appears to be the feature of most human diseases. The general mechanism of cell damage involves the excessive uncontrolled production of reactive oxygen species resulting in the intensification of lipid peroxidation processes and damaging of macromolecules. These processes are generally accompanied by a decrease in the concentration and/or activity of natural antioxidants. Moreover, the exhaustion of the antioxidant capacity of the organism is among the key reasons leading to the development of pathological states. The maintenance of the prooxidant-antioxidant balance by the systematic use of products or dietary supplements, the components of which exhibit antioxidant activity, can be considered as a part of a strategy for the prevention and control of diseases associated with oxidative stress. The current work aims to study the free radical scavenging activity of two experimental poly-component complexes. Antioxidant properties of complexes were determined in experiments in vitro. The estimation of total antioxidant activity, nitric oxide, hydrogen peroxide radical, and superoxide anion scavenging activity was performed. The results revealed that both complexes have the potentials to prevent the formation of free radicals and can be used as agents with antioxidant properties. It was established that the effect of complex 1 and 2 is complex and first of all aimed at the prevention of the formation of dangerous free radicals by reducing the level of hydrogen peroxide. The additional mechanism involves the chelating of metal ions, in particular ferrous iron. The antioxidant ability exhibited by complex 1 was found to be higher than the total antioxidant activity of complex 2. Complex 1 was more effective in the ability to neutralize superoxide anion-radicals while complex 2 showed a high percentage inhibition of Fe2+-induced lipid peroxidation.

The aim of this work to investigate the impact of the radiation damage in the materials by the proton energy irradiation. The damage parameter used in the evaluation is displacement per atom (DPA) in material as a function of proton energy. Stopping and Range of Ions in Matter (SRIM) code was used to calculate the total vacancy and the number of atomic displacements based on the Norgett-Robinson-Torrens model by difference energies for proton irradiation damage. The option of this code was calculated by using Ion Distribution and Quick Calculation of Damage (Kinchin-Pease) for Fe and Cu target and also Full damage cascade (F-C) was chosen for only Fe. The result is that, the prediction of the F-C model are higher than the K-P calculation. Comparisons has been made with an international standard definition of DPA.

Problems of Applying Professional Standards in the Russian Federation
Authors: Khronova I. A.
Published: November 2020

As part of the study, the author identifies the main theoretical and practical problems of the application of professional standards in the Russian Federation. In modern economic conditions, the introduction of professional standards seems to be a reasonable and necessary measure, since it allows companies to achieve greater labor productivity, improve the quality of production and products, reduce the costs of recruiting and enhance competitiveness. Professional standards contain a detailed description of the knowledge and work skills necessary for a specialist, while qualification reference books are no longer able to meet modern business requirements. Despite the formed legal framework for professional standards, there are a number of problems that need to be resolved in the practice of regulatory legal acts provisions implementation in this area. In particular, the issues of regulating the procedure for the development and implementation of professional standards remained out of sight of the legislator; in addition, the problem of the conceptual and categorical apparatus is obvious. As part of the study, the author develops recommendations for improving the labor legislation of the Russian Federation.
