Authors: Achiriloaiei Daniel , Medeleanu Mihai
Published: February 2020

Degradation and breakage of Aluminium Clad Steel Reinforced (ACSR) conductors leads to power outages that have catastrophic impact from an economic, social and national security point of view. Frictions, vibrations, corrosion, as well as other chemical compounds from the environment, can be the main source of the damages. Environment provides much of the time less restrictive conditions than those designed in the standards. In this respect, issues of optimization and development of current diagnostics and forecasting techniques personalized on geographic areas arise.

Published: February 2020

In this paper, we report the relation between fabric characteristics and animal model cornea modifications associated with extended use of fluoro-siloxanyl styrene rigid gas permeable contact lens. Siloxanyl styrene and fluoromethacrylate rigid gas permeable contact lens is a newly designed optical medical device used in orthokeratology with an FDA approval of continuous wear for up to 30 days. To assess the influence on the cornea an animal model was used and histological data were collected. Scanning electron microscopy (SEM) was performed on the used lenses. Our conclusions concedes that with respects of the material, doctor�s slit lamp lens observation on regular basis should be considered as surface debris and lens scratches can influence the cornea in extended wear.

Published: February 2020

Drug facilitated sexual assault (DFSA) can be defined as sexual activity occurring where consent is invalid or absent due to the effects of drugs and/or alcohol. We report a rare case of pro-active drug facilitated sexual assault involving non-oral administration of sedative-hypnotic intoxicant without primary alcoholic ingestion. For eight years, a male nurse administered sedative-hypnotic drugs to patients admitted to the hospital unit, in order to subsequently maintain sexual intercourse with them. The intravenous administration without primary alcoholic ingestion distinguishes this case of pro-active drug facilitated sexual assault from those presented in associated literature.
Estudio de la usabilidad de una nueva herramienta de evaluación cognitiva, el CogVal, en una muestra de panameños y españoles
Authors: Solís Abdel
Published: February 2020

La población a nivel mundial está envejeciendo, y paralelo a dicho envejecimiento se encuentran todas las enfermedades que se asociadas a él, entre ellas los trastornos cognitivos. Actualmente hay una tendencia a aprovechar el aumento del uso de las TICs, y en este caso aplicado a la valoración de las capacidades cognitivas en el envejecimiento. El objetivo del presente estudio se centró en analizar la usabilidad de una aplicación de valoración cognitiva aplicado a una muestra de panameños y españoles quienes luego contestaron a un cuestionario de usabilidad y se analizó la relación entre la frecuencia de uso de TICs, edad y educación. Los resultados indican que la poca frecuencia de uso de las TICs puede estar asociado a opinión de la facilidad de uso de la aplicación, todas las demás variables no muestran asociación con la usabilidad del Cogval y ésta opinión no depende del país donde se aplique la prueba. Además hay una tendencia de las personas mayores por preferir las evaluaciones cognitivas informatizadas. Estos resultados indican que el Cogval, puede ser usado y entendido por la población panameña y permitirá continuar con el proceso de validación de dicha prueba.

 

AbstractThe world´s population is growing older, and along with age come certain associated diseases, including cognitive disorders. Recently, ICTs have grown increasingly popular and widely used. This tendency has grown as a helpful tool to assess cognitive disorders and describing the aging brain. This study’s main goal is to analyze the use of a computer-based app (COGVAL) to evaluate cognitive processes with a Panamanian and Spanish population. Administering also a usability survey to further study any relationships between the frequency of ICT use, age, and literacy. Results have shown that low frequency use of ICTs may be related to participants describing the COGVAL app as an easy one to use. Other variables measured show no relation to the usability of the COGVAL app, this is regardless of the country of the participants. In addition, older people tend to prefer computer based assessments. These results suggest that the Panamanian population, also helping to facilitate the validation of this test, may easily use the COGVAL app.
A Stock-Flow Consistent Political Business Cycle: Kalecki’s 1943 Model Revisited
Authors: Fisher Eloy
Published: February 2020

El presente trabajo analiza un modelo de ciclo económico político coherente y consistente donde la interacción entre la deuda financiera, la distribución del ingreso y la política fiscal está mediada políticamente por la influencia relativa de los trabajadores y de las empresas sobre la política gubernamental y los bienes proporcionados públicamente. En países donde los impuestos son una alternativa políticamente costosa para generar ingresos fiscales, la deuda financia la actividad de expansión fiscal para aumentar inicialmente los salarios y aumentar la producción. Sin embargo, los mecanismos institucionales mantienen a esos conductores a raya e impulsan un ciclo de parar y avanzar, como sugirió Kalecki en su documento de referencia de 1943. Descubrimos que el empuje de los intereses laborales contra las partes interesadas del negocio lleva a dinámicas no lineales sobre la deuda y los déficits y crea incertidumbre sobre el camino del crecimiento a largo plazo.
El proceso de Reducción de la Pobreza Multifuncional en Panamá a través de las prácticas internacionales de Responsabilidad Social Corporativa
Authors: Tomás de Cavia Fernando
Published: February 2020

Uno de los beneficios que aporta la Inversión Extranjera Directa (IED) cuando la misma se acompaña de prácticas y políticas de Responsabilidad Social Corporativa (RSC) es la reducción de la pobreza, especialmente cuando dichas inversiones se realizan en países en vías de desarrollo. Panamá es uno de los mayores receptores de Inversión Extranjera Directa de la región latinoamericana y, por lo tanto, debería poder utilizar los recursos, tangibles e intangibles, suficientes como para poder reconducir sus altos índices de pobreza, considerando todos los aspectos multifuncionales de esta. No obstante, en el año 2017, el índice de pobreza multifuncional de Panamá sitúa en torno al 19.1% la población que se encuentra en dicha circunstancia, lo que representa en términos absolutos 777,752 personas y un total de 138,410 hogares. No parece que las buenas prácticas empresariales estén obteniendo los beneficios deseados en la sociedad panameña por lo que es fundamental conocer qué está causando esta carencia y cuáles son las fórmulas para reconducirla.

Published: February 2020

Los diagnósticos analizados y detallados en este trabajo, indican que tanto el sector turismo como la industria hotelera están pasando por momentos bastantes difíciles los cuales han venido disminuyendo el nivel de su negocio y su competitividad en el mercado, ocasionando el despido de personal y el cierre de operaciones de muchas empresas en Panamá. Se realizaron entrevistas a varios actores relevantes del sector turismo en Panamá donde la pregunta principal fue identificar los ocho (8) problemas más sobresalientes con relación al servicio al cliente y cómo visualizar la solución de los mismos. Se analizó de qué manera, desde el punto de vista de cada uno de ellos, se podrían mejorar estas debilidades y problemáticas. Los resultados obtenidos evidenciaron que la calidad del servicio al cliente en las empresas hoteleras presenta carencias y debilidades como: Baja capacidad de gestión y supervisión por parte de los mandos medios. Baja satisfacción laboral y motivación por parte de los colaboradores. Escaso personal capacitado con dominio del idioma inglés. Falta de interés en trabajar en el sector turismo en horarios rotativos y laborar en días festivos. Los propietarios no ofrecen oportunidades de capacitación para desarrollo de habilidades y destrezas del personal. Falta de interés en ofrecer un servicio y atención al cliente en forma eficiente. Deficiente cultura turística. Falta de incentivos y de promoción laboral. Entre los métodos utilizados está el Análisis Estructural que consiste en interrelacionar las variables en un cuadro de doble entrada Matriz de Análisis Estructural. Esta matriz se elabora de manera cualitativa (existencia o no de relaciones), pero también cuantificable. De esta forma, se distinguen varias intensidades de relaciones directas: fuertes, medias, débiles y potenciales. Luego se procede a la búsqueda de las variables claves utilizando Sistemas y Matrices de Impactos Cruzados (SMIC) y Multiplicación Aplicada a una Clasificación (MICMAC). Cada variable lleva aparejado un indicador de motricidad y dependencia.

Published: February 2020

En este trabajo se estudia un conjunto de especímenes óseos hallados en el sitio El Rincón, ubicado en un médano en la península de Puerto San Julián, Provincia de Santa Cruz. En los sectores de mayor concentración de materiales, al noreste del sitio, se delimitaron y analizaron tres locus de restos óseos. Estos fueron segmentados en cuadrículas con el propósito de efectuar el relevamiento sistemático in situ de las características taxonómicas y anatómicas. La muestra analizada se compone por huesos largos, en su mayoría de Lama guanicoe, que presentan evidencias de fractura. A su vez desde una perspectiva morfológica y funcional se evalúa el origen de estas fracturas. Además se identifican los agentes y procesos tafonomicos que pudieron alterar el material. Los restos óseos del conjunto se habrían originado en actividades de procesamiento y consumo de presas, evidenciadas en las prácticas de fractura transversal/marcado perimetral, en su empleo como machacadores y en otras marcas antrópicas. A su vez estos huesos podrían haber sufrido sucesivos procesos de enterramiento y desenterramiento durante los cuales actuaron agentes antrópicos y naturales, como el viento y el agua provocando su alteración y meteorización.

Published: February 2020

En el presente trabajo se propone indagar sobre las prácticas alimentarias de los grupos cazadores-recolectores y pescadores que habitaron el litoral fluvial bonaerense hace ca. 2000 años. Estos hábitos han sido estudiados desde diferentes metodologías, tales como el análisis de microrrestos vegetales preservados en tiestos cerámicos e instrumentos de molienda, que han permitido identificar tareas de procesamiento de vegetales silvestres. También se han trabajado aspectos morfo-funcionales a través de técnicas arqueométricas, reconociendo diferentes tipos de vasijas con funciones análisis de ácidos grasos absorbidos y adheridos en las paredes de contenedores cerámicos arqueológicos y experimentales. Estos datos han sido interpretados en forma conjunta con la información procedente del registro arqueofaunístico, arqueobotánico y tecnológico y han permitido avanzar en la interpretación de estas prácticas. Para tal fin se han seleccionado dos sitios arqueológicos: Las Marías, correspondiente a las primeras ocupaciones registradas en la zona, y San Clemente VI, perteneciente a un momento más tardío. La elección de los sitios con cronologías diferentes se fundamenta en el interés de analizar los cambios y/o continuidades en las prácticas vinculadas al procesamiento de alimentos y manejo del entorno.

Interactions at the cell membrane and pathways of internalization of nano-sized materials for nanomedicine
Authors: Francia Valentina , Montizaan Daphne , Salvati Anna
Published: February 2020

Nano-sized materials have great potential as drug carriers for nanomedicine applications. Thanks to their size, they can exploit the cellular machinery to enter cells and be trafficked intracellularly, thus they can be used to overcome some of the cellular barriers to drug delivery. Nano-sized drug carriers of very different properties can be prepared, and their surface can be modified by the addition of targeting moieties to recognize specific cells. However, it is still difficult to understand how the material properties affect the subsequent interactions and outcomes at cellular level. As a consequence of this, designing targeted drugs remains a major challenge in drug delivery. Within this context, we discuss the current understanding of the initial steps in the interactions of nano-sized materials with cells in relation to nanomedicine applications. In particular, we focus on the difficult interplay between the initial adhesion of nano-sized materials to the cell surface, the potential recognition by cell receptors, and the subsequent mechanisms cells use to internalize them. The factors affecting these initial events are discussed. Then, we briefly describe the different pathways of endocytosis in cells and illustrate with some examples the challenges in understanding how nanomaterial properties, such as size, charge, and shape, affect the mechanisms cells use for their internalization. Technical difficulties in characterizing these mechanisms are presented. A better understanding of the first interactions of nano-sized materials with cells will help to design nanomedicines with improved targeting.

Comets are small bodies thought to contain the most pristine material in the solar system. However, since their formation ≈4.5 Gy ago, they have been altered by different processes. While not exposed to much electromagnetic radiation, they experience intense particle radiation. Galactic cosmic rays and solar energetic particles have a broad spectrum of energies and interact with the cometary surface and subsurface; they are the main source of space weathering for a comet in the Kuiper Belt or in the Oort Cloud, and also affect the ice prior to the comet agglomeration. While low-energy particles interact only with the cometary surface, the most energetic ones deposit a significant amount of energy down to tens of meters. This interaction can modify the isotopic ratios in cometary ices and create secondary compounds through radiolysis, such as O2 and H2O2 (Paper II). In this paper, we model the energy deposition of energetic particles as a function of depth using a Geant4 application modified to account for the isotope creation process. We quantify the energy deposited in cometary nucleus by galactic cosmic rays and solar energetic particles. The consequences of the energy deposition on the isotopic and chemical composition of cometary ices and their implication on the interpretation of cometary observations, notably of 67P/Churyumov Gerasimenko by the ESA Rosetta spacecraft, will be discussed in Paper II.

Published: February 2020

The high-magnification microlensing event MACHO-97-BLG-28 was previously determined to be a binary system composed of either two M dwarfs or an M dwarf and a brown dwarf. We present a revised light-curve model using additional data from the Mt. Stromlo 74″ telescope, model estimates of stellar limb darkening, and fitting of the blend separately for each telescope and passband. We find a lensing system with a larger mass ratio, q = 0.28 ± 0.01, and smaller projected separation, s = 0.61 ± 0.01, than those presented in the original study. We revise the estimate of the lens–source relative proper motion to μ
rel = 2.8 ± 0.5 mas yr−1, which indicates that 16.07 yr after the event maximum the lens and source should have separated by 46 ± 8 mas. We revise the radius of the source star using more recent reddening maps and angular diameter–color relations to R
* = (10.3 ± 1.9) R
⊙. K- and J-band adaptive optics images of the field taken at this epoch using the NIRC2 imager on the Keck telescope show that the source and lens are still blended, consistent with our light-curve model. With no statistically significant excess flux detection we constrain the mass,

xGASS: H i Fueling of Star Formation in Disk-dominated Galaxies
Authors: Wang Jing , Catinella Barbara , Saintonge Amélie , Pan Zhizheng , Serra Paolo , Shao Li
Published: February 2020

We introduce a method to estimate the H i mass within the optical radius of disk galaxies from integrated H i spectra, with an uncertainty of 0.09 dex. We use these estimates to study how inner H i fuels star formation in late-type disk galaxies. We find that star formation rate (SFR) at a given stellar mass (M
*) is well correlated with the inner H i surface density (

) and inner H i mass-to-stellar mass ratio. For the massive (M
* > 1010
M
⊙) disk galaxies, higher SFR at a given stellar mass is also related to higher efficiency of converting inner H i to molecular gas, but no such correlation is found for the total H i mass. The highest

and the fastest depletion of the total neutral gas within the optical disks are found in the most compact and star-forming disk galaxies at a given stellar mass. These results highlight the important role of inner H i as an intermediate step of fueling star formation in disk galaxies.
Dissecting the Phase Space Snail Shell
Authors: Li Zhao-Yu , Shen Juntai
Published: February 2020

The ongoing vertical phase-mixing, manifesting itself as a snail shell in the

phase space, has been discovered with Gaia DR2 data. To better understand the origin and properties of the phase-mixing process, we study the vertical phase-mixing signatures in arches (including the classical “moving groups”) of the

phase space near the solar circle. Interestingly, the phase space snail shell exists only in the arches with

km s−1, i.e., stars on dynamically “colder” orbits. The snail shell becomes much weaker and eventually disappears for increasingly larger radial action (J

R
), quantifying the “hotness” of orbits. Thus, one should pay closer attention to the colder orbits in future phase-mixing studies. We also confirm that the Hercules stream has two branches (at fast and slow V

), which may not be explained by a single mechanism, since only the fast branch shows the prominent snail shell feature. The hotter orbits may have phase-wrapped away already due to the much larger dynamical range in radial variation to facilitate faster phase-mixing. To explain the lack of a well-defined snail shell in the hotter orbits, the disk should have been perturbed at least 500 Myr ago. Our results offer more support to the recent satellite-disk encounter scenario than the internal bar-buckling perturbation scenario as the origin of the phase space mixing. The origin of the more prominent snail shell in the V

ϕ
color-coded phase space is also discussed.

Se vêtir comme un empereur : les déviances d’Élagabal
Authors: Bérenger Agnès
Published: February 2020

L’apparence extérieure d’un empereur fait partie des critères qui fondent sa légitimité. Dans le cas d’Élagabal (218-222), les auteurs antiques, et en particulier Hérodien, ont porté une attention particulière à ses goûts vestimentaires et insistent volontiers sur son accoutrement, qualifié de barbare, et convenant davantage à une femme qu’à un homme. Le port ostentatoire de vêtements en soie, de couleur pourpre et or, et de longues tuniques couvrant ses bras et ses jambes, dénote un goût pour le luxe peu compatible avec la simplicité affectée par Auguste, le fondateur du régime. Les parures de bijoux de prix, les couronnes d’or et de pierres précieuses et le maquillage, tout concourt à faire d’Élagabal une figure contraire aux attentes des Romains et à expliquer, au moins en partie, le rejet dont il fit l’objet.
Rex abhorret a sanguine ? De l’effusion à l’abstinence, Charles VII et le sang versé
Authors: Collard Franck
Published: February 2020

À la mort de Charles VII, tous ses thuriféraires lui prêtèrent une sainte horreur du sang et de son effusion. Enclin à épargner l’ennemi du champ de bataille et à faire grâce de leur vie aux pires coupables de lèse-majesté, le monarque commença pourtant sa carrière politique dans le bain de sang de 1418 avec la sanglante mise à mort de son adversaire Jean sans Peur. L’article vise à comprendre le rapport psychologique, politique et idéologique au sang du monarque « très victorieux » et à mesurer l’importance de « l’économie de sang humain » dans la communication politique du temps.
Jean Cavaillès dans l’héritage de Léon Brunschvicg : la philosophie mathématique et les problèmes de l’histoire
Authors: Michel Alain
Published: February 2020

La philosophie de l’histoire des mathématiques entretient chez Cavaillès un rapport étroit et contrasté, avec celle que Brunschvicg expose dans La Modalité du jugement (1897). L’activité du jugement scientifique y est dite mixte , entre jugements (idéaux) d’intériorité et jugements (réalistes) d’extériorité. La forme mixte de l’activité historique de la connaissance est la modalité du possible . D’où une épistémologie historique qui revendique la filiation idéaliste kantienne et rejette l’idéalisme spéculatif. Cavaillès, penseur de la nécessité créatrice du devenir mathématique, réduisant le rôle de la possibilité et de l’aventure intellectuelle dans son histoire, se détache par là d’un maître dont un Canguilhem serait demeuré plus proche. L’histoire mathématique récente, en préparant à un Kronecker sa revanche sur les conceptions ensemblistes abstraites qui inspiraient le nécessitarisme de Cavaillès, conduit à reconsidérer le radicalisme qui l’opposait à la philosophie brunschvicgienne de la modalité du jugement.
Cavaillès ou la disparition du sujet ?
Authors: Pradelle Dominique
Published: February 2020

L’œuvre de Cavaillès est associée à la critique de fond des pensées du sujet en philosophie des mathématiques, liée à une inspiration spinoziste. Il s’agit ici d’interroger le rapport de la pensée de Cavaillès à la philosophie transcendantale : la position fondamentale de Cavaillès consiste-t-elle à rejeter en philosophie des mathématiques toute philosophie du sujet mathématicien , c’est-à-dire toute thèse d’engendrement des objectités idéales des mathématiques par les actes de la conscience ? Implique-t-elle l’exclusion, hors du champ de la philosophie mathématique, de la notion d’acte subjectif ? Faut-il lui substituer l’idée d’un ordre objectif, anonyme et dialectique d’engendrement de nouvelles idées rationnelles à partir d’idées données ? Nous analyserons les critiques du sujet kantien émises par Cavaillès, pour voir comment la conceptualité hégélienne permet de penser en sa spécificité l’historicité des idéalités mathématiques, paradoxale progressivité de contenus omnitemporels.
Grandeur et misère du social. L’itinéraire philosophique d’Axel Honneth
Authors: Carnevali Barbara
Published: February 2020

Dans cet article, je retrace et discute l’itinéraire philosophique d’Axel Honneth, depuis La Lutte pour la reconnaissance jusqu’à ses récents essais Le Droit de la liberté et L’Idée du socialisme . Dans la première partie, le concept programmatique de pathologie sociale sera mis en relation avec celui de « sécularisation de la théodicée » formulé par Ernst Cassirer – à savoir, l’attribution de la responsabilité de la souffrance humaine à la société – et avec l’héritage des Lumières légué par Jean-Jacques Rousseau. Dans la deuxième partie, une fois précisée la position occupée par Honneth dans la tradition de la théorie critique francfortoise, j’aborderai ses propositions théoriques ; je distinguerai notamment deux modèles normatifs correspondant à deux phases successives de la pensée honnethienne : la lutte pour la reconnaissance d’une part, qui s’appuie sur une anthropologie formelle à valeur universelle ; et la théorie de la liberté sociale d’autre part, qui réactualise la doctrine hégélienne de l’éthicité en s’appuyant sur un modèle historique et internaliste de critique sociale reconstructive. Dans la troisième partie, je me pencherai sur la « divinisation du social » inhérente au projet d’une critique des pathologies sociales, ainsi que sur la confiance excessive qu’Honneth semble accorder à la force normative de l’intersubjectivité.
Modified Posterior Soft Tissue Release for Management of Severe Knee Flexion Contracture
Authors: Bhan S , Rath S
Published: February 2020

ABSTRACT: A modified posterior soft tissue release has been used in treating severe flexion contracture of the knee in 30 patients (36 knees). The operative technique has been modified with respect to the skin incision, and lengthening of the medial hamstrings. It is performed without a tourniquet. Postoperative skeletal traction was applied with gradual increasing weight to rapidly correct residual deformity. The deformity was fully corrected in 30 knees. The only complication was superficial skin necrosis over a small area, which occured in two knees. In six knees, 10° of flexion deformity persisted after treatment. In four additional knees, 10° of flexion deformity recurred due to lack of continued therapy. The modified posterior soft tissue release operation gave good results without any serious complications.
Helping Family Members Manage Medication Administration Hassles
Authors: Travis Shirley S. , Kao Hsueh-Fen S. , Acton Gayle J.
Published: February 2020

Managing the medication regimens of dependent older adults in the home is a complex issue for family caregivers. The tasks involved can include helping the older adults manage their own medications or may require involvement in the purchasing, scheduling, and administering of multiple medications for serious conditions. The hassles associated with this responsibility are now known to be associated with increased caregiver strain. In this article, we provide an overview of the body of research on medication administration hassles and offer a tool to assess family caregivers who are involved in this important aspect of care.
Contribución al conocimiento de los Micrambe Thomson, 1863 (Coleoptera: Cryptophagidae) Afrotropicales
Authors: Otero J. C. , Pereira J. M.
Published: February 2020

Se presenta la primera síntesis de las especies afrotropicales del género Micrambe Thomson, 1863 (Coleoptera, Cryptophagidae). Las especies se definen de acuerdo con las características de su morfología externa y la configuración de su edeago. Se incluyen claves para la identificación de subgéneros y especies de las aproximadamente 79 especies conocidas. Se analizan las características del género Micrambe de África oriental y se señalan las constantes diferencias del edeago con las especies de dispersión paleártica, sugiriendo que las especies africanas constituyen un grupo filogenético distinto a las paleárticas. Se describen dos nuevas especies: Micrambe borjai sp. nov. y Micrambe cuccodoroi sp. nov. Nuevas combinaciones son propuestas: Micrambe angulata (Bruce, 1952) de Cryptophagus (Micrambe) angulatus Bruce, 1952; Micrambe capensis (Redtenbacher, 1867) de Cryptophagus capensis Redtenbacher, 1867; Micrambe gracilipes (Wollaston, 1871) de Cryptophagus gracilipes Wollaston, 1871 y Micrambe nigrothoracica (Bruce, 1952) de Cryptophagus (Micrambe) nigrothoracicus Bruce, 1952. Se añaden dos enmiendas justificadas: Micrambe modesta Grouvelle, 1906 en lugar de Micrambe modestus Grouvelle, 1906 y Micrambe brevipilis (Bruce, 1951) en lugar de Micrambe brevipila (Bruce, 1951). Se citan trece especies por primera vez para la fauna de algunos países afrotropicales: dos para la República de Angola: Micrambe basuto (Bruce, 1957) y Micrambe eichelbaumi Grouvelle, 1908; tres para la República Democrática Federal de Etiopía: Micrambe difficilis (Bruce, 1955), Micrambe discolor (Bruce, 1951) y Micrambe (Neomicrambe) figurata (Bruce, 1951); una para Isla Reunión: Micrambe consors Grouvelle, 1906; tres para la República de Kenia: Micrambe (Neomicrambe) figurata (Bruce, 1951), Micrambe (Neomicrambe) helichrysi (Scott, 1935) y Micrambe nigrothoracica (Bruce, 1952); una para la República de Ruanda: Micrambe (Neomicrambe) alluaudi (Scott, 1935); una para la República Unida de Tanzania: Micrambe acerba (Bruce, 1951) y una para la República de Uganda: Micrambe (Neomicrambe) crateris (Scott, 1935).
