Microbial biobanking – cyanobacteria-rich topsoil facilitates mine rehabilitation
Authors: Williams Wendy , Chilton Angela , Schneemilch Mel , Williams Stephen , Neilan Brett , Driscoll Colin 
Published: May 2019

Abstract. Restoration of soils post-mining requires key solutions
to complex issues through which the disturbance of topsoil incorporating soil
microbial communities can result in a modification to ecosystem function.
This research was in collaboration with Iluka Resources at the
Jacinth–Ambrosia (J–A) mineral sand mine located in a semi-arid chenopod
shrubland in southern Australia. At J–A, assemblages of microorganisms and
microflora inhabit at least half of the soil surfaces and are collectively
known as biocrusts. This research encompassed a polyphasic approach to soil
microbial community profiling focused on “biobanking” viable cyanobacteria
in topsoil stockpiles to facilitate rehabilitation. We found that
cyanobacterial communities were compositionally diverse topsoil microbiomes.
There was no significant difference in cyanobacterial community structure
across soil types. As hypothesised, cyanobacteria were central to soil
microprocesses, strongly supported by species richness and diversity.
Cyanobacteria were a significant component of all three successional stages
with 21 species identified from 10 sites. Known nitrogen-fixing cyanobacteria
Symploca, Scytonema, Porphyrosiphon,
Brasilonema, Nostoc, and Gloeocapsa comprised more
than 50 % of the species richness at each site and 61 % of the total
community richness. In the first study of its kind, we have described the
response of cyanobacteria to topsoil stockpiling at various depths and ages.
Cyanobacteria are moderately resilient to stockpiling at depth and over time,
with average species richness greatest in the top 10 cm of the stockpiles of
all ages and more viable within the first 6 weeks, indicating potential for
biocrust re-establishment. In general, the resilience of cyanobacteria to
burial in topsoil stockpiles in both the short and long term was significant;
however, in an arid environment recolonisation and community diversity could
be impeded by drought. Biocrust re-establishment during mine rehabilitation
relies on the role of cyanobacteria as a means of early soil stabilisation.
At J–A mine operations do not threaten the survival of any of the organisms
we studied. Increased cyanobacterial biomass is likely to be a good indicator
and reliable metric for the re-establishment of soil microprocesses.
Recrystallization processes, microstructure and crystallographic preferred orientation evolution in polycrystalline ice during high-temperature simple shear

Abstract. Torsion experiments were performed in polycrystalline ice at high temperature
(0.97 Tm) to reproduce the simple shear kinematics that are believed to
dominate in ice streams and at the base of fast-flowing glaciers. As clearly
documented more than 30 years ago, under simple shear ice develops a
two-maxima c axis crystallographic preferred orientation (CPO), which
evolves rapidly into a single cluster CPO with a c axis perpendicular to the
shear plane. Dynamic recrystallization mechanisms that occur in both
laboratory conditions and naturally deformed ice are likely candidates to
explain the observed CPO evolution. In this study, we use electron
backscatter diffraction (EBSD) and automatic ice texture analyzer (AITA) to
characterize the mechanisms accommodating deformation, the stress and strain
heterogeneities that form under torsion of an initially isotropic
polycrystalline ice sample at high temperature, and the role of dynamic
recrystallization in accommodating these heterogeneities. These analyses
highlight an interlocking microstructure, which results from
heterogeneity-driven serrated grain boundary migration, and sub-grain
boundaries composed of dislocations with a [c]-component Burgers vector,
indicating that strong local stress heterogeneity develops, in particular,
close to grain boundaries, even at high temperature and high finite shear
strain. Based on these observations, we propose that nucleation by bulging,
assisted by sub-grain boundary formation and followed by grain growth, is a
very likely candidate to explain the progressive disappearance of the
c axis CPO cluster at low angle to the shear plane and the stability of the
one normal to it. We therefore strongly support the development of new
polycrystal plasticity models limiting dislocation slip on non-basal slip
systems and allowing for efficient accommodation of strain incompatibilities
by an association of bulging and formation of sub-grain boundaries with a
significant [c] component.
El uso y abuso de marcas

Published: May 2019

Es un tema de interés, debido a que el uso y abuso de los derechos de propiedad industrial, específicamente el de marcas puede favorecer o afectar a propietarios y consumidores de las mismas, en el caso de éstos últimos la preferencia en marcas descansa en la confianza por su calidad, duración, etc.En realidad, el tema desencadena una diversidad de fenómenos, pero me referiré exactamente a dos aspectos que tienen que ver directamente con el uso y abuso de marcas: el régimen de competencia desleal y el interés de los consumidores como bien a proteger. De esa manera se presentan por separado y al final se hace un breve análisis al respecto.
Programas implementados para erradicar la pobreza extrema sobre la base del objetivo 1 del Milenio Programa de la Red Solidaria

El estudio sobre la pobreza ha sido abordado desde diferentes ópticas atendiendo a sus múltiples dimensiones en que prevalece el de la pobreza estructural como efecto del circulo vicioso de la misma.El Salvador es un pais tipificado como subdesarrollado y con un nivel de dependencia económica arraigado que se refieja en la balanza de pagos, en cuanto a que señala como ingreso principal las remesas del exterior y no por la producción interna, la cual ocupa un segundo lugar.
Renta programada en sistema de ahorro para pensiones : caso enfermos terminales
Authors: Sorto Rivas Francisco 
Published: May 2019

En este artículo se plantea la necesidad de corregir las expectativas de vida utilizadas para calcular pensiones en sistemas de capitalización individual, bajo la modalidad de renta programada, para aquellos pensionados con enfermedades terminales o crónicas, para quienes la ciencia médica permite anticipar, con bastante precisión, el tiempo medio de vida que tienen; esto con el ánimo de ajustar el valor de sus pensiones durante tales circunstancias para que disfruten, en vida, del saldo acumulado en su cuenta y reciban a la vez la atención médica necesaria que mejore la calidad de ésta. Para ello no es necesario reformar la Ley en nuestro país, por ejemplo, sino que bastaría con revisar la normativa secundaria referida al método utilizado para calcular las pensiones, concretamente en lo relativo al número de años (expectativas de vida) en que debería dividirse dicho saldo, observando para tales propósitos, la evaluación médica pertinente.
Acuerdo de paz y crecimiento económico
Authors: Vidal Juan Héctor 
Published: May 2019

El Acuerdo de Paz firmado en Chapultepec el 16 de enero de 1992, constituye sin duda uno de los hechos más importantes desde que El Salvador surgió a la vida independiente. Es más, en la historia reciente, ese acontecimiento constituye un hito a nivel latinoamericano, porque significó ponerle fin a un largo conflicto interno por la vía negociada, lo que trajo consigo, entre otras cosas, algo inédito: la transformación de una de las fuerzas contendientes en partido político. Habiendo coincidido la guerra civil con una etapa en la que toda América Latina atravesaba por grandes problemas económicos, cuya duración y profundidad dieron lugar a la llamada década perdida y que en el caso salvadoreño fue más aguda precisamente por los efectos directos del mismo conflicto se esperaba que, con su finalización, el país retornara a la normalidad económica. Además, el modelo económico que se había puesto en marcha años antes sustentado en los principios de la economía de mercado, conforme a las ideas en boga, ya estaba generando resultados en el momento en que se firmó la paz.
Lento crecimiento, baja movilidad y exclusión una combinación mortal para obstaculizar el desarrollo
Authors: Molina Francisco 
Published: May 2019

El Salvador no es un país que les da a nuestros jóvenes muchas oportunidades para salir del círculo de la pobreza y desigualdad en el que nacieron. Situación que exige la necesidad de implementar políticas públicas que permitan disminuir las desigualdades y falta de oportunidades para evitar que se siga transmitiendo la desigualdad intergeneracional. Una mayor equidad, no obstante, su valor intrínseco, no es suficiente, también es indispensable generar un clima de negocios que incentive la inversión y generación de empleo. A continuación, se presentará brevemente el panorama económico y social, la situación de inequidad en el acceso a bienes, servicios, y a la educación y sus repercusiones en las expectativas y movilidad social. Así como sugerencias para reducir las inequidades y mejorar la eficiencia de las políticas públicas.
On the modular functions arising from the Theta constants
Authors: Kirmaci Ugur S. 
Published: May 2019

Some modular functions arising from the theta constants $ \vartheta_2(\tau)$, $ \vartheta_3(\tau)$, $ \vartheta_4(\tau)$ are investigated. Let $n$ be an odd square-free positive integer as in [4,7]. It is obtained a necessary and sufficient condition that $ \varphi_{\delta,\rho,3}(\tau)=\prod_{\delta|n,\rho|n}\Big({\vartheta_3(\delta\tau) \over\vartheta_3(\rho\tau)}\Big)^{r_\delta}$ is invariant with respect to transformations in $ \theta(n)$. Also, It is deduced that $ \varphi_{\delta,\rho,i}(\tau)$ is a modular function on $ P^{-2}\theta(n)P^2$, $ \theta(n)$, $P^{-1}\theta(n)P$, for $ i=2,3,4$, respectively. Thus, the result of L. Wilson's paper [7] is generalized. Furthermore, let $ m$ and $ n$ denote positive integers. Let $ r$, $ r_1$, $ r_2$ be integers such that $ r(m-1)(n+1)\equiv 0({\rm mod}~8)$, $ r_1(m-1)(n-1)\equiv 0({\rm mod}~ 8)$, $ r_2^2(n-m)(nm-1)\equiv 0({\rm mod}~8)$, it is shown that $ T_{m,n,i}^r(\tau)=\Big({\disp{\vartheta_i(\tau)\vartheta_i(n\tau)\over\vartheta_i(m\tau) \vartheta_i (mn\tau)}}\Big)^r$, $ H_{m,n,i}^{r_1}(\tau)=\Big({\disp{\vartheta_i(m\tau)\vartheta_i(n\tau)\over \vartheta_i(\tau)\vartheta_i(mn\tau)}}\Big)^{r_1}$ and $ \Phi_{m,n,i}^{r_2}(\tau)=\Big({\disp{\vartheta_i(m\tau)\over\vartheta_i(n\tau)}\Big)^{ r_2 }} $ are modular functions on $ \theta(mn)$, when $ i=3$. Similar results are deduced for $ P^{-2}\theta(mn)P^2$ and $ P^{-1}\theta(mn)P$, the suffixes 3 being replaced by 2 and 4, respectively. Therefore, the modular functions used in B. C. Berndt's paper [1] is rewritten for theta constants.

Conversion of methane to more reactive compounds such as methanol has drawn attention for many years. Hierarchical ZSM-5 zeolite has been used as support of metal oxide catalyst to facilitate the partial oxidation of methane to methanol. The NaZSM-5 zeolite was synthesized hydrothermally using double-template techniques, in which tetrapropylammonium hydroxide (TPAOH) and polydiallyldiammonium chloride (PDDA) were used as primary and secondary templates, respectively. HZSM-5 was prepared through multiple NH4+ exchange of NaZSM-5 followed by calcination. Co oxide-modified ZSM-5 (Co/NaZSM-5 and Co/HZSM-5) were prepared through impregnation method. Then, the zeolites were extensively characterized using scanning electron microscope (SEM), X-ray diffraction (XRD), AAS, Fourier transform infrared (FTIR), 27Al solid-state NMR, microbalance, and surface area analysis. The catalytic test was performed in batch reactor, and the product was analyzed with GC-FID. Reaction condition and acidity of ZSM-5 as support catalyst were studied. As a result, when using Co/HZSM-5 as catalyst, percentage (%) yield of methanol was increased with longer reaction time. On the other hand, the percentage (%) yield decreased when Co/NaZSM-5 was employed. Introduction of trace amount of oxygen to the gas mixture showed different results. Furthermore, the prospect of synthesis of ZSM-5 using natural resources and using biogas are also explored.
La militance syndicale dans la très petite entreprise : le cas du conseiller du salarié
Authors: Sin Philippe , Grima François 
Published: May 2019

Notre étude cherche à comprendre la militance dans de très petites entreprises en France. Plus précisément, nous cherchons à cerner la forme prise par la militance dans ce contexte et les motivations du militant. Pour cela, nous nous appuyons sur 29 entretiens semi-directifs réalisés auprès de conseillers du salarié des deux principales entités syndicales. Mobilisant la littérature sur l’engagement et le travail militant, nous avons dégagé trois profils : le « bon soldat », le « défenseur des droits » et le « combattant ».Le « bon soldat » a une stratégie de valorisation de son syndicat. Sa militance s’exprime par un accueil soigné au salarié et un alignement sur sa position dans sa relation avec l’employeur. Son engagement militant montre qu’il cherche à préserver un équilibre entre son engagement syndical et sa vie privée. Le second profil, le « défenseur des droits », est attiré par les dimensions juridiques de son engagement auprès des salariés. Le conseiller du salarié ayant ce profil cherche à construire une stratégie de partenariat avec le salarié afin d’obtenir le moins de sanctions pour ce dernier. Pour lui, sa militance est d’abord motivée par la défense des droits du salarié. Le dernier profil, « le combattant », est très expérimenté syndicalement et il s’intéresse davantage à la relation interpersonnelle. Le conseiller du salarié de ce profil met en place une stratégie de conflits. Il s’engage auprès du salarié sans condition. Il lui propose une prise en charge totale jusqu’à le substituer et il ira jusqu’à mobiliser son syndicat, cela sans hésitation.L’étude met en exergue la diversité de la militance dans les très petites entreprises grâce à des conseillers du salarié qui restent fidèles à leur organisation syndicale et qui s’engagent auprès des salariés en s’appropriant la militance. Cette dernière vient questionner globalement les pratiques syndicales dans les très petites entreprises.

Published: May 2019

AbstrakMetode Focus Group Discussion (FGD) merupakan pendekatan yang umum digunakan untuk mengumpulkan data/informasi pada penelitian kualitatif, tidak terkecuali penelitian keperawatan yang saat ini semakin populer menggunakan metode FGD sebagai metode pengumpulan data. Metode ini memiliki karakteristik utama yaitu menggunakan data interaksi yang dihasilkan dari diskusi diantara para partisipannya. Kekuatan utama metode FGD terbukti dapat memberikan data yang lebih mendalam, lebih informatif, dan lebih bernilai dibanding metode lainnya. Namun, pelaksanaan yang optimal dari metode ini masih menjadi perdebatan yang dilaporkan pada banyak literatur dan konsensus metode FGD sebagai metode yang ideal untuk pengumpulan data belum disepakati oleh banyak ahli penelitian. AbstractFocus Group Discussions (FGD) method is a common approach for data collection in qualitative research projects, without exception in nursing research in recent years. The primary characteristic of this method is to use interaction data resulting from discussion among participants. The primary strength of the FGD method is that it can provide rich data, more informative, and valuable insight which can not be discovered through other methods. However, the optimal execution of the FGD method has been debated in the literatures, and consensus related to ideal methodology has not been achieved by researchers.
