LANDSCAPE PLANT OBSERVATIONS FROM THE LSU AGCENTER, 2004
Authors: Owings Allen D. , Holcomb Gordon E. , Witcher Anthony L. , Broyles C. Allen , Bush Edward W.
Published: June 2019

Performance evaluations of numerous annual and perennial herbaceous ornamentals were conducted in landscape settings in 2004 at the LSU AgCenter in Baton Rouge. A mid-summer through fall evaluation of Kong coleus found no difference in flowering performance and visual quality ratings of the five available cultivars. In a sun/shade study, Kong coleus cultivars in 60% shade were about 50% shorter than those in sun. Other impressive coleus have been Aurora Black Cherry and Mississippi Summer Sun. The Stained Glassworks series of coleus have been average performers. The Son series of lantanas (Sonrise, Sonset, Samson, Sonshine) have been top performers in terms of visual quality and continual bloom. All-America daylilies most prevalent to rust symptoms have included Judith, Leebea Orange Crush, Starstruck, Lady Lucille, and Chorus Line. Some rust has also been noted on Plum Perfect and Frankly Scarlet. Profusion Apricot and Profusion White have been less susceptible to Xanthomonas bacterial petal blight than Profusion Fire, Profusion Cherry, and Profusion Orange. Earth Kind roses, being promoted by Texas A&M, are being evaluated for landscape performance along with black spot and powdery mildew susceptibility. Most problematic cultivars thus far have included Georgetown Tea, Clotilde Soupert, Nacogdoches, Reve d'Or, New Dawn, Souvenir de St. Anne's, Spice, Lamarque, Puerto Rico, Sarah Jones, Ducher, and Louis Philippe. Lady Bird cosmos have been good late summer/early fall landscape performers.
A HISTORY OF SOUTH FLORIDA GARDENING—A REVIEW OF MABEL WHITE DORN AND MARJORY STONEMAN DOUGLAS' THE BOOK OF TWELVE FOR SOUTH FLORIDA GARDENS
Authors: Beckford M. , Garofalo J.F. , County Miami-Dade
Published: June 2019

Published by the South FL Garden Club in 1928, when Mabel Dorn was president and Marjory Stoneman Douglas—famous for championing the protection of the Everglades—was garden editor of the Miami Herald, The Book of Twelve lists twelve tried and true flowering and shade trees, large to small shrubs, etc. for southern Florida, but also includes some plants which are now tried and true invasive species. The book was reviewed in July 2004 by the Univ. of Florida (FL)/Miami-Dade Florida Yards and Neighborhoods (FYN) Extension Agent in response to a request from a local garden club, which as a club project, had decided to re-print and distribute the book to its 100 members. Because it might encourage the use of invasive species, the review was discussed at a seminar on ecologically sustainable alternatives to invasive species. One recommended plant, Schinus terebinthefolius (Brazilian pepper) is now prohibited by the FL Dept of Environmental Protection and considered a noxious weed by the FL Dept of Agric and Consumer Services. The FL Exotic Plant Pest Council (FEPPC) considers five plants Category I invasives, i.e., exotics altering native plant communities, displacing natives, changing community structures or ecology, or hybridizing with natives. These include Lantana camara, Lonicera japonica, Abrus precatorius and Asparagus africanus. Ten plants are FEPPC Category II invasives, exotics increasing in abundance or frequency, but not yet altering plant communities as extensively as Category I species: Cestrum diurnum, Murraya paniculata, Sesbania punicea, Cryptostegia grandiflora, Jasminum sambac, Antigonon leptopus, Macfadyena unguis-cati, Asystasia gangetica, Wedelia trilobata, and Tradescantia fluminensis.
HEIGHT CONTROL OF HERBACEOUS PERENNIALS FORCED USING NIGHT-INTERRUPTED LIGHTING UNDER NURSERY CONDITIONS
Authors: Keever Gary J. , Kessler J. Raymond
Published: June 2019

In previous studies, night-interrupted lighting (NIL) promoted earlier flowering of summer-blooming herbaceous perennials grown under outdoor nursery conditions in the southeastern U.S. However, NIL promoted excessive plant height, thus reducing product quality. Our objective was to control plant height of Coreopsis grandiflora `Early Sunrise' (ES) and Rudbeckia fulgida `Goldsturm' (RG) grown under NIL with plant growth retardants (PGR) without offsetting earlier flowering promoted by NIL. Treatments under NIL were three rates of daminozide, daminozide plus chloromequat, flurprimidol, uniconazole, and NIL and natural controls. Plant height was reduced 3% to 38% in ES and 8% to 31% in RG and time to visible bud was unchanged by all PGR treatments compared to the NIL control. Time to visible bud was unchanged in RG by all PGR treatments and flurprimidol in ES, but the remaining PGR treatments increased time to visible bud compared to the NIL control in ES. Only ES plants treated with daminozide and daminozide plus chloromequat at the two highest rates and all rates of uniconazole were similar in height to the natural control. RG plant heights with the two highest rates of flurprimidol and uniconazole and the highest rate of daminozide plus chloromequat were less than the natural control; heights of plants in the remaining PGR treatments were similar to the natural control. Quality rating was unchanged in RG but was increased in ES by all PGR treatments compared to the NIL control.
IMPACT OF GAP AND GMP ON FEVERFEW PLANT MARKET-ABILITY
Authors: Rushing James W. , Dufault Robert J. , Hassell Richard L. , Shepard B. Merle
Published: June 2019

Feverfew has aspirin-like properties and has been utilized for the treatment of pain, particularly migraine headache. Parthenolide is the sesquiterpene lactone believed to be responsible for the medicinal properties. The potential for utilizing existing tobacco production and handling systems for the production and postharvest handling of feverfew was investigated. In year one, 8 commercial tobacco growers each planted about one-half acre of feverfew (Tanacetum parthenium L. Schulz-Bip.). The yield of dry herb varied among farmers from about 122 to 772 (55 to 350 kg) pounds per half-acre. The parthenolide content of the dried herb from most producers was within the range desired by industry, but four factors precluded its salability: a) presence of foreign matter, primarily weeds; b) excessive ash content due to contamination from sandy soils; c) mold resulting from processing with excessive moisture content, and; d) insect infestation (tobacco beetles Lasioderma serricorne) during storage. All of these limitations resulted from the failure to implement good agricultural aractices (GAPs) and good manufacturing practices (GMPs) during production and handling of the product. A second planting of the feverfew was carried out with strict attention to GAPs and GMPs. In this trial, all of the dried feverfew met the requirements for sale. Here we report on the management of production and handling systems for feverfew that can enable growers to produce high quality herbs that meet the high standards for medicinal use.
USING DISTANCE EDUCATION IN A POSTHARVEST COURSE
Authors: Sanders Douglas C. , Osborne Dennis J. , Reyes Luz
Published: June 2019

Land-grant institutions throughout the US face declining resources in general. Particularly reduced is institutional ability to offer core graduate and upper level undergraduate courses in production agriculture and agricultural science. For example, while North Carolina (NC) State University is still able to offer a wide range of upper-division production courses in Horticulture, many sister institutions are facing restrictions on offerings in Fruit and Vegetable Production and Floriculture courses. New areas such as Sustainable Agriculture and Organic Farming also justify course offerings but few resources exist to create and teach such courses. At NC State, distance education (DE) is able to begin overcoming these problems in several ways. First, high demand, low-seat-available classes such as Postharvest Physiology can offer additional enrollment for credit if open to DE students. Second, courses offered asynchronously or with alternative delivery strategies (such as the videotapes distributed in this course) students having course/time conflicts in a semester can enroll simultaneously in two campus time-conflicted courses, completing both successfully. The framework for the Postharvest course now being taught via DE and how it came to gain institutional support will be discussed in this paper.
Molecular and morphological characterization of Paurodontella composticola n. sp. (Nematoda: Hexatylina, Sphaerulariidae) from Iran
Authors: Esmaeili Mehrab , Heydari Ramin , Kheiri Ahmad , Ye Weimin
Published: June 2019

A new species of the genus Paurodontella, P. composticola n. sp., collected from Nazar Abad City, Alborz Province, Iran, is described and illustrated. The new species has a body length of 803–1053 μ m (females n = 10) and 620 and 739 μ m (males n = 2). The cuticle is weakly annulated with four lateral lines. Cephalic region is annulated and continuous with body contour. The stylet is 8.0 to 9.0 μ m long with asymmetrical knobs. Esophageal basal bulb is present with a small posterior extension projecting into the intestine. Excretory pore is situated at the level of esophageal basal bulb region. Post-uterine sac is 5 to 8 μ m long and uterus is without diverticulum. Tails of both sexes are similar, short and sub-cylindrical. Males have 24 to 25 μ m long bursa leptoderan and spicules 24 or 25 µm long. A non-branching oviduct is present to form a uterine diverticulum; the new species is closely related to five known species of the genus, namely P. asymmetrica, P. balochistanica, P. densa, P. iranica and P. niger. It most closely resembles P. iranica, but differs from it morphologically by a shorter stem-like extension projecting into lumen of intestine and male with sub-cylindrical tail vs conoid. In addition to morphological comparisons, the molecular phylogenetic analyses based on 733 bp of the partial sequence of 28S D2/D3 expansion segments of the large subunit rDNA gene (LSU) revealed this as a new species.
Short‐Term Impacts of Conservation Agriculture on Soil Physical Properties and Productivity in the Midhills of Nepal
Authors: Laborde John P. , Wortmann Charles S. , Blanco‐Canqui Humberto , McDonald Andrew J. , Baigorria Guillermo A. , Lindquist John L.
Published: June 2019

Core Ideas

Aggregation and time‐to‐pond were improved under conservation agriculture.

Conventional practice had a higher sorptivity rate than conservation agriculture.

Maize yields were similar for conservation agriculture and conventional practice in the first year of production.

Maize yields were less in conservation agriculture than in conventional practice in the second year due to patchy plant stands in conservation agriculture.

There were no differences in yield between conservation agriculture and conventional practice for rapeseed or wheat.

Conservation agriculture (CA) is a management system characterized by zero or minimum tillage, permanent soil cover with crop residue or plant growth, and crop rotation. This study investigated the impact of conservation tillage, crop type, and planting date on crop productivity and the soil physical properties for 2 yr following conversion to CA. After 2 yr, average mean weight diameter of dry aggregates for the 0‐ to 5‐cm and 5‐ to 10‐cm soil depths were 45 and 24% greater in the CA treatment than the conventional practice (CP) treatment, respectively. However, soil sorptivity was about three times slower in CA than in CP for rapeseed (Brassica napus L. toria) rotation treatments, but only 62% slower in CA than CP for wheat (Triticum aestivum L.) rotation treatments. Soil bulk density to a depth of 15 cm was greater in CA (1.30 g cm−3) than CP (1.24 g cm−3), but only for late‐planted treatments. Maize (Zea mays L.) yields for CA were not different from CP in the first year, but were 1.4 Mg ha−1 for CA and 5.0 Mg ha−1 for CP in the second year due to poor stand establishment under CA. There were no effects of CA on dry‐season rapeseed and wheat. Results suggest that during the transition of CP to CA, soil physical properties can be improved but yields may remain constant or decline. Achieving equivalent yield outcomes between CA and CP will largely depend on equivalent stand establishment.
Sesame Sole Crop and Intercrop Response to Fertilizer in Semi‐Arid Niger
Authors: Maman Nouri , Garba Maman , Abdou Gonda , Wortmann Charles S.
Published: June 2019

Core Ideas

Sesame sole crop was highly responsive to fertilizer phosphorus.

The profit potential for applied phosphorus was greater for sole crop than intercrop.

Sesame did not respond to fertilizer nitrogen and potassium.

Sesame‐pearl millet had greater productivity than the sole crops.

Manure phosphorus had a high fertilizer phosphorus equivalent.

Sesame (Sesamum indicum L.) is a market crop of small‐scale farmers, particularly women, in the Sahel. Guidelines for soil fertility management may help to boost the productivity and profitability of sesame production. Research was conducted in 2016 and 2017 at Maradi and Magaria in Niger to determine nutrient response functions for sesame as a sole crop and intercropped with pearl millet (Pennisetum glaucum L.). Sesame yield was doubled with high consistency across site‐years with 30 kg P ha−1 applied and the P response function was determined. Sesame yield was not increased with N and K application. Manure application increased sesame grain yield by 25% when no fertilizer was applied and by 6% with 15 kg P ha−1. The estimated fertilizer P equivalent value of manure P was 1.72 kg kg−1 for no fertilizer P, indicating that manure application increased crop uptake capacity for indigenous soil P through, for example, increased root growth. Intercropped sesame and pearl millet yields decreased by about 41% of sole crop yields on average but the land equivalent ratio was about 1.2 with intercropping compared with sole crop production. The economically optimal P application rate ranged from 14 to 34 kg P ha−1 for sesame sole crop and from 0 to 15 kg P ha−1 for the intercrop with pearl millet, with the ranges resulting from varying fertilizer P use costs relative to crop value. Fertilizer P use has high profit potential for sesame sole crops in the Sahel but less potential for sesame–millet intercrops.
Does No‐Tillage Mitigate Stover Removal in Irrigated Continuous Corn? A Multi‐Location Assessment
Authors: Stewart Catherine E. , Roosendaal Damaris L. , Sindelar Aaron , Pruessner Elizabeth , Jin Virginia L. , Schmer Marty R.
Published: June 2019

Core Ideas

Long‐term residue removal with irrigation may degrade soil despite no‐tillage.

Residue removal was assessed across three irrigated corn no‐tillage sites.

Stover removal decreased soil organic C stocks by 6% and soil aggregation by 12%.

Stover removal did not affect soil microbial biomass or composition.

No tillage alone is not adequate to reduce erosion and maintain soil function.

No‐tillage (NT) may ameliorate negative effects on soil properties from corn (Zea mays L.) stover harvest, but few long‐term irrigated continuous corn production systems have been evaluated to test this hypothesis. We evaluated three long‐term no‐tillage sites (4–13 yr) in Nebraska and Colorado that spanned a range of precipitation and soil organic carbon (SOC) levels. We measured SOC, δ13C of SOC, soil microbial biomass (SMB) and composition (i.e., phospholipid fatty acids, PLFAs), and water stable aggregation at all sites under stover retention vs. removal (∼60%). Surface SOC stocks (0–30‐cm depth) increased across the gradient and were 46.4, 57.4, and 63.1 Mg C ha–1 for Colorado, central Nebraska, and eastern Nebraska, respectively. Overall, residue removal decreased SOC stocks by 6% and soil aggregation by 12% in the 0‐ to 30‐cm depth. The δ13C signature of SOC indicated less new surface C storage under residue removal in Colorado, but not at the two Nebraska sites. Residue harvest did not decrease SMB or change soil microbial community structure, suggesting that high plant productivity buffered community composition from stover harvest impacts under NT but stimulated microbial activity levels that led to SOC loss. The high rates of stover removal used in this study decreased SOC stocks and aggregation at all sites compared to residue retained treatments, suggesting that no‐tillage alone was not sufficient to maintain erosion protection and soil function.

Forensic science is an interdisciplinary area that is intimately related between the fields of physics, biology, chemistry, mathematics and forensic opportunity sciences, with the aim of supporting criminal investigations and civil justice. Forensic Entomology enters as the most promising and attention-grabbing course, especially for its versatility in identifying morphological characteristics in species identification, requiring new analytical tools such as microcopy and molecular analysis. With regard to the Molecular Age in Forensic Science, new technologies can be applied in the research field regarding necrobiota, a new and promising molecular tool that indicates the possible places of displacement of the body and people involved; phenotyping as an analytical tool for the phenotypic identification of the possible appearance of the suspect or missing person; epigenetics in the identification of suspects in the case of homozygous twins. All new tools open up the numerous possibilities for further development of Forensic Science, allowing greater agility in resolving criminal investigations.
Lipase and their different industrial applications: A review

Published: June 2019

Enzymes are also known natural catalysts. Lipases are flexible enzymes that are mostly used. These enzymes are found extensively all over the animal and plant kingdoms, likewise in molds and bacteria. Among all identified enzymes, lipases have concerned the mainly biotechnological attention. This review paper discusses the characteristic, microbial origin and application of lipases. The present review discussed about different characteristics and sources (fungal, bacteria’s) of lipase. The present article also discussed about different bioreactors used for lipase production and different biotechnological applications (food, detergent, paper and pulp, biofuels etc) of lipases. An observation to considerate lipases and their applications as bulk enzymes and high-value of production, these enzymes are having huge impact in different bioprocesses.
Phenotypic and molecular characterization of different isolates of Lactobacillus plantarum from four Nigerian fermented foods for use as probiotics in aquaculture
Authors: Diyaolu Daniel Olusegun , Ekundayo Fatuyi Olanipekun , Fasakin Emmanuel Adedayo , Adebayo Olabode Thomas
Published: June 2019

This study aimed at identifying Lactobacillus plantarum from fermented maize, sorghum, soyabeans and cassava, using both phenotypic method and 16S RNA sequencing, as well as determining similarity or otherwise among recovered isolates. Biochemical characterization of isolates recovered from these fermented foods revealed that L. plantarum occurred in all fermented food examined, with slight variation in their abilities to ferment some sugars (arabinose, dulbitol and mannitol). These phenotypically identified isolates were also confirmed to be L. plantarum by 16S rRNA sequencing, having close relatedness (> 95%) with other isolates available in the gene bank. However, intragenomic heterogeneity of the 16S rRNA gene was observed among these L. plantarum isolates. The result obtained in this finding pinpoints the need to evaluate the beneficial effects each strain of L. plantarum may possess as promising probiotics, rather than generalising common effects for all strains of this bacterial species.
El liderazgo vietnamita después del XII Congreso del Partido Comunista de Vietnam y la continuidad de las reformas económicas
Authors: De Miranda Mauricio , Vidal Pavel
Published: June 2019

El presente artículo analiza los cambios en el liderazgo político vietnamita a partir de la celebración del 12º Congreso del Partido Comunista Vietnamita (PCV). Estos cambios son definitorios para la continuidad de la reforma y la inserción internacional de Vietnam, y son claves que requieren conocer los empresarios y funcionarios colombianos para poder penetrar un mercado que por el momento no ha sido aprovechado al máximo. En el nuevo Buró Político vietnamita fueron ratificados sólo siete de los 16 miembros del anterior equipo. Se ha fortalecido, al menos temporalmente, la posición del Secretario General Nguyen Phu Trong, lo que, junto a otras designaciones, otorga un leve giro hacia una tendencia “conservadora”. Pero ello no implica que se vayan a revertir las reformas, sino más bien que se reforzará el control político e ideológico del PCV.
buen vivir como sustento de la acción colectiva de los actores sociales y la comunidad del municipio de Choachí (Cundinamarca) frente a los megaproyectos
Authors: Muñoz Laura Marcela , Vergara María Alejandra
Published: June 2019

En el presente artículo se realiza una descripción sobre los problemas que actualmente afectan a la comunidad de Choachí, ya que siguiendo lo planteado por el plan nacional de desarrollo del gobierno del presidente Juan Manuel Santos Todos por un nuevo país (20142018), se enmarca la construcción de megaproyectos asociados a la locomotora minero - energética como medio para el desarrollo económico del país.
De dicho plan de desarrollo, los proyectos que tienen una relación directa con el municipio de Choachí, se resaltan la Perimetral de Oriente Bogotá (poB), la red eléctrica Nueva Esperanza y el ejercicio minero ejercido en el corredor de páramos del oriente de Cundinamarca.Los proyectos, anteriormente mencionados, tienen un impacto muy fuerte en la comunidad, pues, en términos sociales y ambientales afectan las dinámicas territoriales que por tradición tiene el municipio.
Con el comienzo de estos mega-proyectos, como respuesta y reacción, la comunidad Chiguana se organizó para ejercer control sobre dichos proyectos, mediante una veeduría ciudadana, apoyada por nuevos actores sociales surgidos en el territorio; Casa maíz, Colectivo talanquera y el apoyo del grupo de abogados ambientalistas, liderado por Juan Ceballos, han sido ejemplo de la resistencia de la comunidad local.
Juventudes rurales en Colombia. Entre la exclusión vergonzante y la tutela incluyente
Authors: Pérez Espitia Milton
Published: June 2019

¿Quiénes son los jóvenes rurales? Parece una pregunta adecuada desde la académica y lo gubernamental, pero resulta insuficiente socialmente por los ejercicios de dominación en los órdenes convencionales del poder y de los grupos sociales dominados en general, los cuales reproducen la dominación a nivel generacional. De acá, resulta interesante la pregunta sobre cómo fue y es ser joven rural en un momento y lugar concreto. De esta manera, el análisis por contrastación de esos dos referentes, es decir, los imaginarios de lo joven rural frente a las condiciones y tramas de vida juvenil, dan cuenta de las clausuras que operan sobre los jóvenes rurales; específicamente, la operación de los imaginarios arbitrarios que justifican la exclusión, pero también la imposición de una inclusión que mantiene relaciones de dominación y dependencia en el marco de una política “sobre” y “para” los jóvenes rurales, desconociéndolos y subsumiéndolos en un orden que les es ajeno. Pero aun en condiciones adversas de violencia armada y económica (la cual se justifica por la violencia simbólica que opera desde los marcadores identitarios de la edad y lo rural), los jóvenes rurales colombianos han generado contra-conductas donde emerge una política “de” estos sujetos sociales.Finalmente, aunque los jóvenes rurales son un grupo autopercibido como totalidad, no significa que no sientan, piensen y actúen con referentes más amplios en sus colectivos locales, regionales, nacionales y globales, invitando a una convergencia en diferencia para una política “con” jóvenes rurales a partir de encuentros urbano-rurales, intergeneracionales, de gobernanzas y multiescalares.Palabras clave: lo joven, lo rural, condiciones juveniles, tramas de vida juvenil, exclusión vergonzante, tutela incluyente.
Innovative strategies and firm growth: evidence from selected fast moving consumer goods firms in Lagos state, Nigeria
Authors: Oluwole Binuyo Adekunle , Ekpe Hillary , Oloyede Binuyo Babatunde
Published: June 2019

Critical to the sustainability and continuous success of every organization is the performance concept. Hence, the cardinal goal of every organization is to achieve sustainable progressive performance for their organization. Several factors have been found to contribute to the performance of an organization. While empirical evidence indicated that innovativeness is one of the major determinants of organizational performance, many fast moving consumer goods (FMCG) were slow in their demonstration of innovative capability and it has been noted that the performance of these companies has not been impressive possibly due to the slow pace of innovativeness in the industry. This study thus investigated the effect of innovative strategies on the growth of selected FMCG firms in Lagos state, Nigeria. Survey research design was adopted for the study. The population comprised 1,337 top and middle level management staff of four notable players in the FMCG industry in the state (Honeywell flower mills Plc, Dangote flower mills, Unilever Nigeria Plc, and Cadbury Nigeria Plc). Through proportionate stratified random sampling technique, 400 out of 1,337 were sampled for the study. Four hundred copies of a validated questionnaire with Cronbach’s alpha reliability coefficient ranging from 0.731 to 0.956 were administered to the sample with a response rate of 84.25%. Data were analyzed using both descriptive, as well as inferential statistics. Finding revealed that innovative strategies had a significant effect on growth of FMCG firms in Lagos state, Nigeria (R2 = 0.724, β = 0.887, t = 29.663, P ≤ 0.05). The study recommends that FMCG firms management need to initiate policies that will enhance innovativeness possibly through creation and proper funding of the research and development department to effectively drive growth of FMCG firms.
Estimation of maximum scour depth downstream of an apron under submerged wall jets
Authors: Aamir Mohammad , Ahmad Zulfequar
Published: June 2019

An analysis of laboratory experimental data pertaining to local scour downstream of a rigid apron developed under wall jets is presented. The existing equations for the prediction of the maximum scour depth under wall jets are applied to the available data to evaluate their performance and bring forth their limitations. A comparison of measured scour depth with that computed by the existing equations shows that most of the existing empirical equations perform poorly. Artificial neural network (ANN)- and adaptive neuro-fuzzy interference system (ANFIS)-based models are developed using the available data, which provide simple and accurate tools for the estimation of the maximum scour depth. The key parameters that affect the maximum scour depth are densimetric Froude number, apron length, tailwater level, and median sediment size. Results obtained from ANN and ANFIS models are compared with those of empirical and regression equations by means of statistical parameters. The performance of ANN (RMSE = 0.052) and ANFIS (RMSE = 0.066) models is more satisfactory than that of empirical and regression equations.
Determination of long-term permissible currents in wires of power supply systems of railways
Authors: FIGURNOV E. P. , ZHARKOV Yu. I. , KHARCHEVNIKOV V. I.
Published: June 2019

In the standard for contact wires made from copper and its alloys, the values of long-term permissible temperatures have significantly decreased. This requires recalculation of previously valid values of long-term permissible currents. Authors considered revised method for calculating the long-term permissible currents, based on a more rigorous consideration of the laws of heat transfer and experimental studies of the conditions of heating and cooling of shaped (contact) and stranded wires. Technique is based on heat balance conditions, using which the sources of greatest inaccuracies become such quantities as cooled surface area, influence of wind direction, meteorological conditions, laws of change in heat transfer coefficient, effect on additional heating of solar radiation. Deviations when these indicators are taken into account by existing methods can cause errors of 40 % or more. Formulas for calculating the actual outer surface of stranded and shaped wires are given. The inadmissibility of calculating the surface area of the wires by their reference diameter is noted. Updated law of the change in heat transfer coefficient for stranded and shaped wires, as well as the degree of its dependence on wind speed and cooled surface, is given based on a summary of extensive domestic and foreign research. It is shown that with the longitudinal direction of the wind, the reduction of this coefficient occurs to a lesser extent than has been assumed so far. Authors propose method for taking into account an increase in the heat transfer coefficient under meteorological conditions characteristic of ice formation. The heat transfer coefficient of shaped and stranded wires in no case can not be taken as for round pipes with smooth surface. Existing method of accounting for solar radiation, which influences the additional heating of wires, leads to an unjustified and repeated exaggeration of this effect, since previously only the radiation incident on the wire was taken into account in the calculations. According to the laws of heat transfer, the temperature of the irradiated body does not depend on the incident, but on the resulting radiation, defined as the difference between the radiations incident on the body and emitted by it in accordance with its temperature. A formula for accounting for such heat transfer is proposed. The above methodology and calculation formulas allow performing reasonable calculations to determine the long-term permissible currents of individual stranded and shaped wires, as well as the contact network as a whole.

Apuntes para una ciudad monstruo: El milusos y la megalópolis
Authors: Cebey Georgina
Published: June 2019

Este texto es un esfuerzo por entender la dimensión social y cultural de la ciudad y la arquitectura vistas a través del cine. A partir de la cinta El milusos (1981), propongo un acercamiento a la complejidad espacial de una Ciudad de México que, desde hace cuatro décadas, ha crecido estrepitosamente hasta desbordar sus límites. Al considerar el cine urbano como una herramienta que lejos de mostrar un paisaje construido es capaz de explicar circunstancias relacionadas con cambios socioestructurales, este trabajo analiza los elementos que intervienen en la construcción visual de la megaurbe propuesta por la cinta en cuestión.

The Appraisal of Conductions
Authors: Bermejo-Luque Lilian
Published: June 2019

I argue that conductions are a special type of inference indeed, but that this does not mean that we need to develop novel standards of inference goodness or specific argument schemes for properly assessing them. Following LNMA’s theoretical framework, I provide a semantic account of conductions and explain the interesting pragmatic properties of a certain type of conductions (i.e., balance of considerations or pro-and-con argumentation) in terms of the rhetorical dimension of the speech-act of arguing.
Asymptotics of quantum channels: conserved quantities, an adiabatic limit, and matrix product states
Authors: Albert Victor V.
Published: June 2019

This work derives an analytical formula for the asymptotic state---the quantum state resulting from an infinite number of applications of a general quantum channel on some initial state. For channels admitting multiple fixed or rotating points, conserved quantities---the left fixed/rotating points of the channel---determine the dependence of the asymptotic state on the initial state. The formula stems from a Noether-like theorem stating that, for any channel admitting a full-rank fixed point, conserved quantities commute with that channel’s Kraus operators up to a phase. The formula is applied to adiabatic transport of the fixed-point space of channels, revealing cases where the dissipative/spectral gap can close during any segment of the adiabatic path. The formula is also applied to calculate expectation values of noninjective matrix product states (MPS) in the thermodynamic limit, revealing that those expectation values can also be calculated using an MPS with reduced bond dimension and a modified boundary.
Impact of technology on Translation and Translation Studies
Authors: Gambier Yves
Published: June 2019

The landscape in translation and interpreting is changing deeply and rapidly. For a long time, but not necessarily everywhere, translation was denied as a need (except for the political and religious powers), as effort (translation being defined as a kind of mechanical work, as substitution of words), and as a profession (translators embodying a subaltern position). Technology is bringing in certain changes in attitudes and perceptions with regards international, multilingual and multimodal communications. This article tries to define the changes and their consequences in the labelling and characterisation of the different practices. It is organised in five sections: first, we recall that translation and interpreting are only one option in international relations; then, we explain the different denials of translation in the past (or the refusal to recognize the different values of translation). In the third section, we consider how and to what extent technology is transforming today practices and markets. The ongoing changes do not boil solely to developments in Machine Translation (which started in the 1960s): community, crowdsourced/collaborative translation and volunteer translation encompass different practices. In many cases, users provide their own translations, with or without formal qualifications in translation. The evolution is not only technical but also economic and social. In addition, the fragmentation and the diversity of practices do have an impact on a multi-faceted market. In the fourth section, we emphasize that there are nowadays different concepts of translation and competitive paradigms in Translation Studies. Finally, we tackle the organisational challenge of the field, since the institutionalisation of translation and Translation Studies cannot remain the same as when there was a formal consensus on the concept of translation.
“A Sensible Image of the Infinite”: Intersemiotic Translation of Russian Classics for Foreign Audiences
Authors: Leontovich Olga Arkad'evna
Published: June 2019

The article is a continuation of the author’s cycle of works devoted to foreign cinematographic and stage adaptations of Russian classical literature for foreign audiences. The research material includes 17 American, European, Chinese, Indian, Japanese fiction films and TV series, one Broadway musical and 9 Russian films and TV series used for comparison. The paper analyses different theoretical approaches to intersemiotic translation, ‘de-centering of language’ as a modern tendency and intersemiotic translation of literary works in the context of intercultural communication. Key decisions about the interpretation of original texts are made by directors and their teams guided by at least three goals: commercial, creative and ideological. Intersemiotic translation makes use of such strategies as foreignization, domestication and universalization. The resignifying of a literary text by means of the cinematographic semiotic system is connected with such transformations as: a) reduction - omission of parts of the original; b) extension - addition, filling in the blanks, and signifying the unsaid; c) reinterpretation - modification or remodeling of the original in accordance with the director’s creative ideas. A challenge and at the same time one of the key points of intersemiotic translation is a difficult choice between the loyalty to the original, comprehensibility for the target audience and freedom of creativity. The research shows that transformations and use of different translation strategies can have both positive and negative consequences. Positive outcomes include: visualization and comprehension of the Russian cultural space; adaptation of Russian experiences for the target culture; retranslation of universal values expressed by the original. Negative consequences result in: the distortion of the original due to insufficient cultural literacy; purposeful deformation of cultural meanings for ideological reasons; erroneous interpretation of the literary text; deformation of the original macromeaning; preservation of the plot, but loss of the in-depth meaning of the original text. Any degree of creative freedom still requires intercultural competence and a careful choice of semiotic signs aimed at expressing the key ideas of the original.
Linguocultural Localization of Movie Titles

Published: June 2019

Due to intensive growth of film production and the expansion of the “market of film consumption”, the need for high-quality translation of feature films into different languages is becoming more and more pressing. While a foreign language film is localized, text elements are not only translated, but also adapted to the culture of the target audience, i.e. we are witnessing transition from one language and cultural code to another. Taking into account their structural, semantic, and functional pragmatic features, film titles are vivid representative materials for the study of modern translation practices in the light of the cultural transference concept (Bassnett 2005, Bastin 1990, Cranmer 2015, Jurt 2007, Кatan 1999, Leinen 2007, Thill 2007, Schreiber 1998, Slyshkin, Efremova 2004, Obolenskaya 2013, Snetkova 2009, Fedorova 2009). The purpose of the article is to identify the strategies of linguocultural localization of French film names for the modern Russian-speaking audience, as well as to determine the degree of its adequacy. Regardless of the choice of the translation strategy, the title should correspond to the plot, thematic focus and ideological and figurative content of the film, while remaining interesting and attractive to the audience. We analysed of eighty-seven French feature films of various genre affiliations (detectives, action films, dramas, melodramas, comedies, thrillers and fantasy), released in Russian from 2000 to 2018, and their translation equivalents. We used the methods of semantic, pragmatic, contextual and linguocultural analysis to identify a set of problems arising in the process of localization of film titles and to offer recommendations for their translation into Russian, considering the communicative specifics of the modern film discourse and the ethnic and cultural characteristics of the target audience.
Mode in Arabic-English Translation: with Reference to the Quran

A rhetorical question has the form of a question but does not perform its function, i.e. does not seek any information but rather, is used to give a specific or rhetoric function such as denial, assertion, testing, equalization and negation. The present study investigates the two English translations that were used in the translation of the Quranic rhetorical questions. In a nutshell, this is a comparative study that aims to discover if the grammatical shifts that had occurred in the two English translations would have an effect on the denial, assertion, testing, and equalization and negation modes of the Quranic rhetorical questions. For this purpose, we had adopted the register theory of Halliday and Hassan (1985) as well as the translation shifts of Catford (1965) in the comparison of the two English translations, namely the Koran Interpreted that was authored by Arberry (1955) and the Noble Quran: English translation of the meanings and commentary as transcribed by al-Hilali and Khan (1996). According to the analyses, the occurrence of grammatical shifts between the two translations had in fact affected the mode of the ST rhetorical questions, their rhetorical meanings and consequently, issues on mode sustenance. Therefore, it can be said that the register theory of Halliday and Hassan (1985) had been a beneficial tool used in the analysis of the translation process.
Development of a mobile device for air purification in the welding industry

Published: June 2019

In the modern world there is a large number of industries, which are in capable of functioning without welding. Is found absolutely everywhere: from the repair of engineering communications to the manufacture of spacecraft. Ventilation is a necessary part of occupational safety, especially when it comes to working in such production. Often, some work must be carried out outside the welding post due to the peculiarities of assigned task, and to bring the exhaust system to the workplace is impossible. In such cases portable filters that take up little space and can be moved to any convenient place in the workshop can be used.
Urbanization and disaster in Accra, Ghana. Does human life matters?
Authors: Owusu-Ansah Emmanuel
Published: June 2019

This article discusses urbanization and disaster in the capital city of Ghana - Accra. Urbanization refers to the population shift from rural to urban residency, the gradual increase in the proportion of people living in urban areas, and the ways in which each society adapts to this change. It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas. Urbanization has its own good and evil. In spite of the positive effect of urbanization, in Ghana one can conclude that urbanization has done more harm than good. This article reveals some catastrophic effects of urbanization and suggested solutions.
Differences in Coaching Needs Among Underrepresented Minority Medical Students
Authors: Najibi Skender , Carney Patricia A. , Thayer Erin K. , Deiorio Nicole M.
Published: June 2019

Background and Objectives: Little is known about how the academic coaching needs of medical students differ between those who are racially, ethnically, and socially underrepresented minority (RES-URM) and those who represent the majority. This single-site exploratory study investigated student perceptions and coaching needs associated with a mandatory academic coaching program, and coaches’ understanding of and preparedness to address these potentially differing needs.
Methods: Coaching needs of second- and third-year medical students were assessed using two initial focus groups and two validation focus groups, one consisting of RES-URM students and the other majority medical students. Coaches were assessed using a cross-sectional self-administered survey designed to determine their perceptions of differing coaching needs of students
Results: Seven themes emerged from the student focus groups. Three of these reflected the coaching relationship, and four reflected the coaching process. RES-URM students expressed stress around sharing vulnerability that was not expressed among majority students. Sixty-eight percent of coaches expressed that RES-URM students would not have differing needs of their coaches. Coaches self-rated as being somewhat (45%), moderately (29%), or very (13%) skilled at coaching RES-URM students.
Conclusions: RES-URM students cite different coaching needs than majority students that most coaches do not recognize. Faculty and program development regarding these unique needs is warranted.
