Authors: Babkova A. S.
Published: August 2019

The article discusses the prospects of building up a collection of ornamental plants belonging to the rose family (Rosaceae Juss.) from local cultivated and wild plant forms in order to expand the zonal assortment of ornamentals for urban landscape gardening in Murmansk Province. Since 2017, the Polar Experiment Station of the Vavilov Institute (VIR) has been engaged in systematic research activities aimed at introduction of ornamental perennial ornamental herbs and shrubs. A promising collection stock has been formed of ornamental plants, currently totaling 198 accessions (160 species) from 40 plant families, including 132 accessions of perennial herbaceous plants (77 genera), 58 of ornamental shrubs (10 genera), and 8 of woody plants (4 genera). Representatives of the family Rosaceae make up 25% of the total number of accessions. The Polar Experiment Station maintains wild and cultivated perennial plants of the genera Geum L., Filipendula L., Potentilla L., Sanguisorba L., Alchimilla L., Dryas L., Spiraea L., Rosa L., Sorbus L., Dasifora Rafin., etc., having ornamental qualities, characterized by high winter hardiness, and not requiring high expenditures for their maintenance. Further expansion of the Rosaceae collection is going to be based on the introduction of ornamentals from the rose family identified in the local vegetation of the Kola Peninsula as well as through the acquisition of accessions from botanical gardens and nurseries located in the areas with climate conditions close to those of the Polar Experiment Station of VIR.

Published: August 2019

Cerca del 40% de la carne roja que se consume en el mundo es provista por los cerdos. Los productores porcinos de nuestro país se encuentran ante el enorme desafío de lograr mejoras productivas con un desarrollo económico sustentable y eficiente, así como implementar tecnologías reproductivas, como la inseminación artificial y la criopreservación de semen. Tales adelantos aún presentan enormes problemas en esta especie. El objetivo de este trabajo fue comparar dos métodos simples de congelamiento para semen porcino, evaluando los parámetros de calidad seminal al momento del descongelado. Las muestras de semen fueron criopreservadas en pajuelas siguiendo el protocolo descripto por Peña y colaboradores en 2003, realizando (grupo tratamiento) o no (grupo control) una modificación en el paso final de congelamiento posterior al envasado en las pajuelas. Las evaluaciones de motilidad y vitalidad se realizaron por microscopía óptica en platina termostatizada y por las técnicas de eosina/nigrosina y la combinación del colorante supravital azul tripán con microscopía de contraste interferencial diferencial, respectivamente. La criocapacitación se evaluó por la técnica fluorescente de clorotetraciclina (CTC). Los resultados de los diferentes experimentos fueron analizados por la prueba t de Student. Las muestras del grupo tratamiento evidenciaron una motilidad significativamente más alta (p<0,05) y una criocapacitación significativamente más baja (p<0,05) que la del grupo control. El porcentaje de espermatozoides vivos en las muestras del grupo tratamiento (33±3) resultó el doble que el del grupo control (16±2). Nuestros resultados demuestran que el método de congelamiento propuesto permite obtener, al descongelado, muestras de una mayor calidad que las obtenidas al descongelar muestras que hayan sido congeladas con el método tradicional.
Interacción genotipo-manejo de la alimentación en la producción de pollos camperos
Authors: Dottavio A M. , Romera B M. , Canet Z E. , Di Masso R J.
Published: August 2019

La producción de carne aviar en sistemas de manejo semi-intensivo es una modalidad ecológica que contempla aspectos vinculados con el bienestar animal. El pollo Campero es un ave con menor velocidad de crecimiento que los parrilleros comerciales, destinado a la producción de carne. El esquema tradicional de alimentación incluye la utilización de tres tipos de alimentos especialmente formulados a tal fin (iniciador, crecimiento y terminador), lo cual introduce complicaciones en el manejo, particularmente en lo referido a la disponibilidad del alimento “crecimiento” para los pequeños productores. Una alternativa que facilitaría el manejo de estas aves es un esquema basado en sólo dos tipos de alimentos: iniciador y terminador. El objetivo de este trabajo fue evaluar el efecto del cambio del manejo tradicional de la alimentación por uno alternativo reemplazando el alimento “crecimiento” por una mezcla de iniciador y terminador, en dos genotipos de pollo Campero con diferente velocidad de crecimiento: el híbrido experimental de tres vías Campero Casilda y el híbrido simple Campero INTA. La evidencia indicó que el cambio en el manejo de la alimentación no afectó el crecimiento, la relación de conversión ni los caracteres a la faena. Ambos grupos genéticos se comportaron de manera equivalente, pudiendo obviarse la inclusión de la categoría “crecimiento” si se la reemplaza por una mezcla de iniciador y terminador.

Authors: Peristiowati Y. , Puspitasari Y. , Indasah
Published: August 2019

This study is aimed at analyzing the anticancer properties of papaya leaf extract, specifically the inhibition of cell proliferation and apoptotic induction through nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and p53 pathways. Twenty-five mice (Mus musculus), aged 2 months and weighing 20–30 g, was injected with 0.5 mg dexamethasone for 7 days. The mice were then injected intracutaneously with 1 ml of HeLa cells (8 × 106 HeLa cells/microliter). The mice were divided into five groups (5 each): negative control (P1) (5% CMC-Na, sodium carboxymethyl cellulose), treatment II (225 mg/kg BW (body weight) papaya leaves methanol extract), treatment III (450 mg/kg BW), treatment IV (750 mg/kg BW), and treatment PV (2 mg alcohol anticancer drug). Papaya leaf extract treatments were applied for 2 weeks. Then, the tumor tissue was isolated for hematoxylin and eosin staining. Immunohistochemical imaging was used to detect Ki-67, caspase-3, NF-κB, and p53 expression. Further analysis was undertaken using the ImmunoRatio software program. The results indicated that administration of papaya leaf methanol extract significantly increased the expression of NF-κB and p53 at a dose of 450 mg/kg BW. Our results also showed that the mice treated with 450 mg of papaya leaf extract per kg of BW (P3) had the largest increase of caspase-3 expression compared to the negative control group. Papaya leaf ethanol extract decreased the cancer cell proliferation index and increased apoptosis of cancer cells in animal models of cervical cancer; it may also work to increase NF-kB expression and expression of the p53 gene.

Analysis of pellets mineral composition using the solutions trees and k-means methods
Authors: Bersenev I. S. , Starostin A. N.
Published: August 2019

Metallurgical properties of pellets to a great extent depend on the peculiarities of their microstructure. Therefore, understanding of the regularity of its evolution in the process of the pellets burning and elaboration on this base optimal methods of technological process control is a rather actual task. Analysis of experiment data of iron ore pellets microstructure accomplished using the methods of solutions trees and cluster analysis. The pellets were produced of ferrous quartzite concentrates. As the base for the investigation results of study of seven samples of iron ore pellets used, made of regular Mikhajlovsky deposit magnetite concentrate (8.3 % SiO2; 65.4 % Fe) with various basicity and MgO content. Processing of the data made in the Orange Canvas media. Classification of phase composition presented by application of decision tree concept. It was shown, that for the pellets glassy binding, an increased content of Na2O and relatively low content of FeO is typical, since the glass phase is formed basing on fusible silicates of waste rock with a high content of alkalis. Sodium and potassium are concentrated in the amorphous (vitreous) phase with a high silicon content. Increasing the MgO content leads to the appearance of a crystalline phase with a decrease in the concentration of alkalis. The decrease of the concentration of alkalis in this case linked with the general increase of the melt due to the pellets fluxing. The pellets fluxing also contributes to the change of composition of iron-bearing phases: with increasing amount of MgO in the pellets, the natural average content of MgO increases in iron-bearing minerals, crystallizing from the melt. CaO is accumulated by silicate components of the pellet structure.

Published: August 2019

Heat capacity is one of most important thermal physic characteristics of materials, allowing determining dependence between amount of heat, input to a body or taken away from it, and alteration of its temperature. The labor intensiveness of the test determination of the heat capacity is rather big. Particularly it is difficult to take into account the influence of changes of chemical composition in the process of heating on changes of their heat capacity. A method of calculation of heat capacity of materials proposed using the additivity method. Difficulties of its determination shown, related to insufficient knowledge of additivity method application. The temperature limits determined, until which it is reasonable to make the calculations of materials heat capacity by the proposed method. An example of calculation of siderite ore physical heat capacity considered. Good enough convergence of the results obtained by calculation and heat capacity data, obtained by experiments shown. Divergence between results of heat capacity determination by experiment method and by calculation using additivity method does not exceed 5%.

Study of the processes, taking place at the large ingots obtaining during steel casting, as well as during its solidification is a rather hard task. Therefore it is reasonable to use for the study of them methods of solidification modelling by application various hard particles (inoculators), being introduced into a melt. Evaluation of the inoculation effect on the solidification process, structure formation and defected zones extension in model ingots carried out. It was determined, that introduction of inoculators during melt casting results in decreasing of the diphasic zone thickness. It was determined also, that introduction of hard particles (inoculators) in the volume of from 6 till 12% results in reducing time of model ingots solidification. An increase the volume of inoculators leads to prevalence of solidification vertical component over the horizontal one. It was determined also, that introduction of inoculators allows increasing the solidification process orientation, that characterized by an increase of linear taper and as a result – the vertical solidification component increase. It was revealed, that introduction of inoculators at the liquid-solid casting leads to changing the heat center location. The introduction of inoculators results to “elongation” of heat center by the solidifying ingot axis, that relates with a quicker advance of the solid phase in vertical direction, as a result of the quick removal of solidifying ingot overheating.

To obtain quality continuously casted billets, electromagnetic stirring (EMS) of melt is used. Most of the industrial CCM operating in Russia are equipped by EMS systems, supplied by foreign companies. EMS stators of foreign production are manufactured as a rule in nonseparable bodies and after their failures the systems must undergo expensive repair abroad at the manufacturers. At VNIIMETMASH the EMS systems of external design were created, in which this problem was solved. The version ЭМПУ 880 (EMPU 880) is completely demountable, that provides conditions for its maintenance and repair under conditions of electric shop of a plant without attraction of expensive materials and equipment. All the materials are domestic made and available. The developed facility comprises 3-phases stator submerged into water, placed in a demountable body of a corrosionresistant steel. The airproofing the body accomplished by a heat-resistant resin. Water supply into the internal area of the body and taking it away is made by end nipples. The terminal unit is arranged in the body having removable covers to connect the power mains. The output ends of the three phases are airtight in the sealing blocks under pressure of 10–12 atm. The designed EMS facility is placed at arranged locations. The peculiarities of the EMS facility design allow to increase up to 585 mm the distance to the plain of maximum rotating forces of the meniscus in the mold. Taking into account that the total energy in the active zone flow decreased and the distance to the meniscus increases, quieter meniscus can be expected at more intensive regimes of the stirring. This circumstance allow improving considerably the quality of the continuously casted billet.

Vaccination is one of the most effective control measure in preventing Streptococcus agalactiae infection. In this study, vaccine coatings were prepared with certain biomaterials such as chitosan, skim milk, and maltodextrin at concentration 1 % or 10 %, and further freeze-dried. Vaccine selected (in vitro) by tests: viability cell, solubility, protein concentration and protein molecular weight. The result of in vitro test showed that chitosan coating at doses 1 % and 10 % were the best in solubility and protein concentration test. Vaccine coated with chitosan was administrated again by injection (in vivo) in nile tilapia (Oreochromis niloticus) before challenged by S. agalactiae. This test consists of six treatments and three replications, i.e. the fish were injected with liquid vaccine (A), Phospat Buffered Saline (PBS) (B), vaccine with chitosan coating 1 % (C), vaccine with chitosan coating 10 % (D), chitosan 1 % (E), and chitosan 10 % (F). Parameters were observed including survival rate, relative percent survival (RPS), antibody titre, and total leucocyte. The results showed that treatment C showed a significant difference (P < 0,05) in survival rate 92.22 ± 3.85 %, RPS 85.21 ± 7.20 %, and antibody titre highest result, but not significant (P > 0,05) to increase total leukocyte in experimental fish against S. agalactiae infection. In conclusion, vaccine freeze dry with chitosan coated 1 % is effective to improve immunity system of nile tilapia.

Javanese long pepper (Piper retrofractum) is known to have androgenic effect, could act as phytosteroid and alternative to masculinization. This research aimed to evaluate the optimum dose of the Javanese long pepper extracts combined with increased rearing temperature on featherfin squeaker masculinization through larva immersion. This research was designed using a completely randomized design with 8 treatments consisted of Javanese long pepper extract doses of 0.0625 mg L-1and 0.125 mg L-1, negative control (without both extract and 17α-metiltestosterone) and positive control (2 mg L-117α-metiltestosterone). Each of them consisted of two different temperature treatments, namely, normal (26-27ᴼC) and 32ᴼC. After five hours treatment, larvae were reared until five months age. The fish age four and then five months were dissected and their gonads were taken for acetocarmine and histology preparation. Beside that the percentage of fish survival, body length, weight gain, and specific growth rate were also recorded in certain period. The result showed that the Javanese long pepper extract dose at 0.125 mg L-1 with normal temperature treatment produced the highest male ratio and significantly different compare with control. Giving this dose to larvae did not affect fish survival and growth, meanwhile increased temperature treatment could not increase the effectivity of Javanese long pepper extract.
