Ontophany and transimmanence in the experience of contemporary media artworks
Authors: Freitas Gabriela
Published: March 2020

How have contemporary media artworks been proposing hybrid experiences, discussing the ontological implications from the experimentation with emerging techniques that alter our way of being-in-the-world? These experiences dialectically articulate aesthetic relations between real and virtual, visible and invisible, human and technological. In this article, we develop a participant observation of two specific works: Generation 244 (2011), by Scott Draves, and Zee (2008), by Kurt Hentschläger. This observation establishes a dialogue with phenomenology as it considers experience and perception as needed prerequisites for the analysis, as proposed by Merleau-Ponty. In this scenario, we have observed that a whole way of partitioning the sensible resets itself and points in the direction of a trans-immanence, generating an integrated knowledge that not only relies on reason, but in a collective wisdom where we can find, according to Didi-Huberman, a ‘light of survival’.
El nacimiento de la dinastía roja: la instauración de la sucesión hereditaria en Corea del Norte (1970-1974)
Authors: Gomà Daniel
Published: March 2020

El establecimiento de una transmisión del poder de padre a hijo marcó un antes y un después en el régimen comunista de Pyongyang y es un caso único en la historia de los sistemas políticos marxistas. Esta sucesión hereditaria dentro de una misma familia tiene su origen en el complejo desarrollo político de la Corea del Norte comunista y, en especial, la instauración de una estructura de poder asociada a la figura de Kim Il Sung. La ausencia de un partido comunista fuerte ante el poder absoluto del líder supremo, el despotismo de un grupo reducido de dirigentes y unos antecedentes internacionales poco propicios favorecieron la designación de Kim Jong Il como sucesor de su padre.

Published: March 2020

The delamination resistance and damage tolerance of traditional honeycomb composites are poor. To overcome these defects, 3D (three-dimensional) integrated woven composites of honeycomb structure were designed, and then manufactured using the vacuum assisted resin transfer molding process (VARTM), based on the 3D self-prepared fabrics used as reinforcements. The load-displacement curves, maximum bending load-velocity curves, and bar chart of energy absorption were determined experimentally and calculated by finite element simulation. The results showed good agreement between experimental and finite element simulation data. The correctness of the model was verified, so the model can be used to predict the mechanical properties of 3D integrated woven composites of honeycomb structure with quadrilateral cross section.

Published: March 2020

A field experiment was conducted to evaluate yield and some qualitative characteristics of four cultivars of sweet basil treated with different levels of nitrogen fertilizer. The experiments were located on the Agricultural Research Station of Khorramabad, Iran, during the 2016-2017 growing season. Treatments were arranged in factorial split-plot-in time in randomized complete block design with three replications. Experimental treatments were four cultivars of sweet basil (Ocimum basilicum ‘Italian Large Leaf’, O. basilicum ‘Mobarakeh’, O. basilicum ‘Cinnamon’ and O. basilicum ‘Thai’), three levels of nitrogen fertilizer (0, 100 and 200 kg ha-1 urea) and three harvests. The highest total dry mass (3482.4 kg ha-1) was related to ‘Italian Large Leaf’ with the application of 200 kg ha-1 urea at the second harvest. The maximum (26.79 kg ha-1) essential oil yield belonged to 100 kg ha-1 urea. The highest concentrations of main constituents of essential oil, except methyl chavicol, 1,8-cineole and methyl cinnamate were obtained by control (without nitrogen fertilizer). Italian Large Leaf cultivar and application of 100 kg ha-1 urea are recommended to access an acceptable agricultural yield and essential oil yield in sweet basil under the environmental condition similar to Khorramabad

Published: March 2020

Optimization of tissue culture and regeneration conditions of eggplant is necessary for achieving different goals such as gene transformation and the development of somaclonal variations. In this study, hypocotyl explants ware used to produce callus in a medium containing different concentrations of NAA and BAP. Moreover, the concentration of the elements Ca, Mn, Mg, Fe and K were measured and analysed between embryogenic and non-embryogenic calli. For shoot elongation, embryogenic calli were transferred to a new culture medium containing 3.5, 4 and 4.5 mg l-1 BAP plus 2 mg l-1 GA3. Finally, produced shoots were rooted in a culture medium containing 1, 1.5 and 2 mg l-1 NAA. Results showed that the best treatment for the embryogenic callus induction was MS medium containing 0.5 mg l-1 BAP plus 0.25 mg l-1 NAA. Two elements, Fe and K, had the highest amount in non-embryogenic calli compare to the embryogenic one. For plant regeneration, MS medium containing 4.5 mg l-1 BAP plus 2 mg l-1 GA3 and 2 mg l-1 NAA were the best treatments for shooting and rooting, respectively. In this study, the best treatments for plant regeneration produced 35 shoots from an explant with 92 % shooting. This regeneration protocol could be useful for gene transformation and micro-propagation studies.
Agro-biological diversity of Slovene ecotypes and standard varieties of cocksfoot (Dactylis glomerata L.): comparison and agronomic value
Authors: ČOP Jure , ELER Klemen
Published: March 2020

Characterisation and evaluation of accessions, e.g. ecotypes of cultivated plants, are the primary task of each agricultural gene bank. In a field experiment, agro-biological diversity and agronomic value of 15 Slovene ecotypes (group 1) and 7 standard varieties (group 2) of cocksfoot (Dactylis glomerata L.) were investigated during the 2015-2019 period. A particular emphasis was given to the comparison of the two groups. The spaced plant experiment with 20 single plants of each treatment entity per replicate was arranged in a randomized complete block design with three replicates. Significant differences among investigated entities were confirmed for all agro-biological traits (p < 0.001). The same holds when the groups were compared (p < 0.001) except for the infection with leaf fungal diseases (p = 0.113).Considering these differences varieties possessed higher agronomic value than ecotypes. In general, the intra-population diversity of Slovene ecotypes was higher than that of standard varieties and represented a higher portion of the ecotype complete variance. Principal component analysis (PCA) of all investigated traits showed a distinctive difference between ecotypes and varieties and higher similarity within the variety group than within the ecotype group. PCA also showed that the ecotypes can be separated into two subgroups, which however cannot be explained by the characteristics of ecotype origin.
Wybrane oprawy ksiąg kanonika gnieźnieńskiego Stanisława Grota (zm. 1624)
Authors: Wajnert Aleksandra
Published: March 2020

Niniejszy artykuł kładzie nacisk na problematykę opraw ksiąg, które znalazły się w kolekcji kanonika gnieźnieńskiego Stanisława Grota. Rozpoznany do tej pory fragment księgozbioru duchownego liczy 45 druków. Wszystkie omówione woluminy należą do zasobu Archiwum Archidiecezjalnego w Gnieźnie. Największą część biblioteki kanonika stanowią druki traktujące o prawie kanonicznym, świeckim oraz kazania. Oprawy tych druków w większości zostały wykonane z desek bądź tektury oraz jasnej skóry dodatkowo pokrytej dekoracjami. Z pewnością przeważają oprawy w typie niemieckiego renesansu o kompozycji ramowej. Sporą część tworzą również oprawy o wymowie kontrreformacyjnej, ozdobione plakietami z monogramem IHS. Jak wynika z badań nad znakami wodnymi, kanonik zaopatrywał się nie tylko u lokalnych introligatorów, ale też m.in. u rzemieślników z Małopolski.

Published: March 2020

Autor podjął próbę ustalenia gdańskich egzemplarzy dwu wydań (Bazylea 1543, 1555) De humani corporis fabrica Andreasa Vesaliusa. W toku badań na terenie Gdańska zidentyfikowano jeden egzemplarz przechowywany od pierwszej połowy XVII wieku w Bibliotece Gdańskiej – dziś stanowiącej jednostkę organizacyjną Polskiej Akademii Nauk. Należał on do wrocławskiego i opawskiego lekarza Wenceslausa Raphanusa (Meerrettich). W gdańskiej książnicy znajduje się wraz z ponad 220 innymi jego dziełami, głównie z zakresu medycyny i nauk pokrewnych. Wiele z tych książek Raphanus otrzymał w darze od zaprzyjaźnionych z nim wybitnych humanistów, jak choćby Andrzeja Dudycza (Andreas Dudith, 1533–1589) czy Amandusa Polanusa (1561–1610). Analiza różnych materiałów źródłowych, w tym przede wszystkim katalogów Biblioteki Gdańskiej oraz gdańskich katalogów aukcyjnych, pozwoliła sformułować ostrożną tezę, iż w księgozbiorach grodu nad Motławą mogło znajdować się nawet 8 różnych egzemplarzy traktatu brukselskiego anatoma Vesaliusa.
Review: Rheology concepts applied to geotechnical engineering
Authors: Tsugawa Juliana Keiko , de Oliveira Romano Roberto Cesar , Pileggi Rafael Giuliano , Boscov Maria Eugenia Gimenez
Published: March 2020

The effect of time on soil properties, noticeable in many earthworks, is recognized by geotechnicians. For example, secondary compression and aging pre-consolidation are considered in geotechnical design, and strain rate is standardized in geotechnical laboratory and field tests. Elastic-plastic models, from rigid-perfect plastic to Modified Cam Clay, which do not consider the effects of time, solve most geotechnical problems. However, solutions for prolonged settlements, landslides, debris flow and mudflow could profit from a deeper understanding of rheological models. In fact, rheological concepts, despite not always clearly stated, have been used to address some of these problems, and may also be important for using new materials in geotechnical practice (tailings, sludge, soil-polymer mixtures and other materials with water content higher than the liquid limit). This paper introduces basic concepts of rheology for geotechnicians, specially highlighting viscoelasticity under simple shear stress, which explains with reasonable accuracy well known phenomena dependent on time in soils. The objective is to bring geotechnicians to rheology and show another important tool to access geotechnical problems. On the other hand, a brief explanation of geotechnical tests is presented for rheologists not acquainted with geotechnical engineering. Geotechnical tests procedures are discussed in the light of rheology concepts, terminology is clarified, examples of application of rheology in geotechnics are presented, and determination of soil rheological parameters by traditional geotechnical tests as well as by tests on concrete is commented.
Silymarin: not just another antioxidant
Authors: Camini Fernanda Caetano , Costa Daniela Caldeira
Published: March 2020

Silymarin (Silybum marianum; SM), popularly known as milk thistle, is an extract that has been used for many centuries to treat liver diseases. In recent years, several studies have shown that SM is not only just another antioxidant but also a multifunctional compound that exhibits several beneficial properties for use in the treatment and prevention of different types of pathologies and disorders. This review aims at demonstrating the main protective activities of SM in diseases, such as cancer, diabetes, hepatitis, non-alcoholic fatty liver disease, alcoholic liver disease, hepatitis C virus, hepatitis B virus, metabolic syndrome, depression, cardiovascular diseases and thalassemia, in addition to its photoprotective activity in in vitro tests and preclinical studies. Its main functions include antioxidant and anti-inflammatory effects, and it acts as modulator of signaling pathways. It has been suggested that SM presents great multifunctional potential and is capable of achieving promising results in different types of research. However, caution is still needed regarding its indiscriminate use in humans as there are only a few clinical studies relating to the adequate dose and the actual efficacy of this extract in different types of diseases.
Crank-Nicolson orthogonal spline collocation method combined with WSGI difference scheme for the two-dimensional time-fractional diffusion-wave equation
Authors: Xu Xiaoyong , Zhou Fengying
Published: March 2020

In this paper, a discrete orthogonal spline collocation method combining with a second-order Crank-Nicolson weighted and shifted Grünwald integral (WSGI) operator is proposed for solving time-fractional wave equations based on its equivalent partial integro-differential equations. The stability and convergence of the schemes have been strictly proved. Several numerical examples in one variable and in two space variables are given to demonstrate the theoretical analysis.

Los vocativos de cariño en español peninsular. Un enfoque desde la Metalengua Semántica Natural
Authors: Bułat Silva Zuzanna
Published: March 2020

En el presente artículo adoptamos el punto de vista de laEtnopragmáticacomo marco metodológico que nos permite interpretar estrategias lingüísticas a través de su relación con ciertos aspectos culturales que motivan el uso de tales estrategias. En concreto, nos proponemos abordar la relación que existe entre losguiones culturalesespañoles y las formas de tratamiento nominales de afecto (vocativos de cariño) usadas en el español peninsular. Los guiones culturales parecen una herramienta muy adecuada para explicitar laspremisas socioculturalesque subyacen a las interpretaciones que hacemos de las funciones que ejercen los vocativos en la cortesía española. Vamos a centrarnos sobre todo en la relación entre los guiones culturales típicamente españoles tales como “expresividad”, “halagar a otro”, “dirigirse a otros con cariño” y “ser amistoso”, así como en los vocativos de cariñoalma, vida, cieloycariño. Para la explicitación, por un lado, del contenido semántico de los vocativos, y, por el otro, de los valores culturales que subyacen a su uso, se aplicará el método de análisis semántico-pragmático desde la perspectiva de laMetalengua Semántica Natural(NSM).
Les bottines suivent-elles les babines? Validation d’un modèle de congruence pour expliquer la santé, la satisfaction et la performance au travail
Authors: Demers Mireille , Tivendell John
Published: March 2020

Les organisations d’aujourd’hui doivent composer avec des exigences de performance de plus en plus élevées tout en prônant le bien-être et la satisfaction de leurs employés. En effet, gérer les problèmes de santé psychologique au travail est devenu pour ces organisations un défi redoutable. Sachant que les modèles actuels ne répondent pas à la demande, la présente étude propose un modèle innovateur fondé sur la congruence des perceptions pour expliquer les extrants individuels tels que la santé mentale, la satisfaction et la performance, ainsi que les extrants organisationnels tels que la productivité et l’efficacité organisationnelles. Le modèle proposé, fondé sur le concept d'autocontradiction de Higgins et sur la théorie de congruence de Caplan, explore les relations triadiques de la congruence des perceptions de l'employé à propos des caractéristiques du travail et celles de l’organisation. L’étude a permis de rejoindre 201 travailleurs francophones âgés de 19 à 70 ans qui ont répondu à un questionnaire quantitatif. Le présent article expose les résultats de cette recherche et leurs implications, tout en suggérant l’importance de réduire les écarts extrêmes de perceptions pour améliorer la santé et la satisfaction des employés ainsi que l’efficacité et la productivité des organisations.
La valorisation organisationnelle : Une source de bien-être et de performance au travail
Authors: Salhi Maroua , Forest Jacques
Published: March 2020

Le présent article se veut une contribution théorique à la documentation scientifique sur la satisfaction de trois besoins fondamentaux : la motivation au travail, le bien-être et la performance au travail. La théorie de l’autodétermination a fait l’objet de plusieurs études (en plus de 45 ans de recherche) et est l’une des théories les plus largement utilisées pour expliquer les relations entre ses concepts. Cette contribution provient de l’intégration du nouveau concept de valorisation organisationnelle, qui est un concept multidimensionnel basé sur des effets interactifs entre la justice organisationnelle, la reconnaissance au travail et la confiance au travail. Selon la documentation, les relations entre ces sous-composantes de la valorisation organisationnelle et les autres concepts ont été démontrées partiellement. À ceci s’ajoute l’absence d'études entre la valorisation organisationnelle et les différents concepts que sont la satisfaction des besoins psychologiques, la motivation, la performance et le bien-être. Ainsi, il a été présumé que la valeur ajoutée de la valorisation organisationnelle semble être prometteuse. Deux objectifs ont été fixés pour vérifier l’apport de ce concept et ses différentes relations : 1) étudier en profondeur la valorisation organisationnelle et analyser le réseau nomologique avec d’autres concepts tels que la satisfaction, la performance, le bien-être et la motivation au travail; 2) proposer un modèle théorique, couplé à des propositions d'hypothèses, qui peuvent expliquer comment il est possible de stimuler la valorisation organisationnelle afin qu’elle soit, en retour, une source de bien-être et de performance au sein de l’organisation. Ces hypothèses seront analysées dans un prochain article.

Integration of Swimming-Related Synaptic Excitation and Inhibition by olig2+Eurydendroid Neurons in Larval Zebrafish Cerebellum
Authors: Harmon Thomas C. , McLean David L. , Raman Indira M.
Published: March 2020

The cerebellum influences motor control through Purkinje target neurons, which transmit cerebellar output. Such output is required, for instance, for larval zebrafish to learn conditioned fictive swimming. The output cells, called eurydendroid neurons (ENs) in teleost fish, are inhibited by Purkinje cells and excited by parallel fibers. Here, we investigated the electrophysiological properties of glutamatergic ENs labeled by the transcription factorolig2.Action potential firing and synaptic responses were recorded in current clamp and voltage clamp from olig2+neurons in immobilized larval zebrafish (before sexual differentiation) and were correlated with motor behavior by simultaneous recording of fictive swimming. In the absence of swimming, olig2+ENs had basal firing rates near 8 spikes/s, and EPSCs and IPSCs were evident. Comparing Purkinje firing rates and eurydendroid IPSC rates indicated that 1-3 Purkinje cells converge onto each EN. Optogenetically suppressing Purkinje simple spikes, while preserving complex spikes, suggested that eurydendroid IPSC size depended on presynaptic spike duration rather than amplitude. During swimming, EPSC and IPSC rates increased. Total excitatory and inhibitory currents during sensory-evoked swimming were both more than double those during spontaneous swimming. During both spontaneous and sensory-evoked swimming, the total inhibitory current was more than threefold larger than the excitatory current. Firing rates of ENs nevertheless increased, suggesting that the relative timing of IPSCs and EPSCs may permit excitation to drive additional eurydendroid spikes. The data indicate that olig2+cells are ENs whose activity is modulated with locomotion, suiting them to participate in sensorimotor integration associated with cerebellum-dependent learning.

SIGNIFICANCE STATEMENTThe cerebellum contributes to movements through signals generated by cerebellar output neurons, called eurydendroid neurons (ENs) in fish (cerebellar nuclei in mammals). ENs receive sensory and motor signals from excitatory parallel fibers and inhibitory Purkinje cells. Here, we report electrophysiological recordings from ENs of larval zebrafish that directly illustrate how synaptic inhibition and excitation are integrated by cerebellar output neurons in association with motor behavior. The results demonstrate that inhibitory and excitatory drive both increase during fictive swimming, but inhibition greatly exceeds excitation. Firing rates nevertheless increase, providing evidence that synaptic integration promotes cerebellar output during locomotion. The data offer a basis for comparing aspects of cerebellar coding that are conserved and that diverge across vertebrates.
Differentiation of alfalfa and sweet clover seeds via multispectral imaging
Authors: Hu Xiaowen , Yang Lingjie , Zhang Zuxin , Wang Yanrong
Published: March 2020

It is hard to remove sweet clover seeds from alfalfa seed lots by conventional methods, affecting the purity of seed lots and resulting losses in for alfalfa hay production as well as seed yield. However, the discrimination of sweet clover seed contaminates in alfalfa seed lots is difficult
without special training. In this study, multispectral imaging with object-wise multivariate image analysis was evaluated for its potential to separate sweet clover and alfalfa seeds. Principal component analysis (PCA), linear discrimination analysis (LDA), partial least squares discriminant
analysis (PLSDA), AdaBoost and support vector machine (SVM) methods were applied to classify seeds of sweet clover and alfalfa according to their morphological features and spectral traits or a combination thereof. The results showed that an excellent classification could be achieved based
on a combination of morphological features and spectral data in a tested data set. Seed classification accuracy was up to 99.58% in a validation set with the LDA model, which was better than the PLSDA (68.19%), AdaBoost (96.95%) and SVM (98.47%) models. Thus, multispectral imaging together
with chemometric multivariate analysis is a promising technique to identify sweet clover seeds in alfalfa seed lots with high efficiency.

Published: March 2020

Analysis of patient-derived DNA samples has identified hundreds of variants that are likely involved in neuropsychiatric diseases such as autism spectrum disorder (ASD) and schizophrenia (SCZ). While these studies couple behavioral phenotypes to individual genotypes, the number and diversity of candidate genes implicated in these disorders highlights the fact that the mechanistic underpinnings of these disorders are largely unknown. Here, we describe a RNAi-based screening platform that uses C. elegans to screen candidate neuropsychiatric risk genes (NRGs) for roles in controlling dendritic arborization. To benchmark this approach, we queried published lists of NRGs whose variants in ASD and SCZ are predicted to result in complete or partial loss of gene function. We found that a significant fraction (>16%) of these candidate NRGs are essential for dendritic development. Furthermore, these gene sets are enriched for dendritic arbor phenotypes (>14 fold) when compared to control RNAi datasets of over 500 human orthologs. The diversity of PVD structural abnormalities observed in these assays suggests that the functions of diverse NRGs (encoding transcription factors, chromatin remodelers, molecular chaperones and cytoskeleton-related proteins) converge to regulate neuronal morphology and that individual NRGs may play distinct roles in dendritic branching. We also demonstrate that the experimental value of this platform by providing additional insights into the molecular frameworks of candidate NRGs. Specifically, we show that ANK2/UNC-44 function is directly integrated with known regulators of dendritic arborization and suggest that altering the dosage of ARID1B/LET-526 expression during development affects neuronal morphology without diminishing aspects of cell fate specification.
El aylluy y la simplicidad transcompleja sostenible

El mundo natural siempre fue un modelo del saber conectivo, coherente y proyectivo. La especialización fragmentó y ¿acaso desarticuló la estructura armónica e integral? Actualmente, las mismas especializaciones, frente al mundo que se ha tornado tan complejo, ha tenido la necesidad de reformular los análisis, la reconstrucción y reinterpretación de nuestra problemática, a fin de repensar nuevamente un mundo sistemático y re-estructurado, enhorabuena a partir del pensamiento complejo y soluciones transdisciplinarias. El presente trabajo evalúa la particularidad de las investigaciones universitarias y replantea los trabajos en equipo desde la perspectiva interdisciplinaria, transcompleja y transdisciplinaria, a partir del pensamiento andino, conectivo e integral, fundamentado en la organización nuclear y armónica entre la naturaleza, el hombre y la sociedad. Desde esta visión se analiza como modelo de investigación para el proceso educativo y el medio ambiente, recuperando el pensamiento aylluy (simplicidad transcompleja, unidad y sostenibilidad). Se aplicó el método descriptivo analítico y cualitativo, con carácter de ensayo.

Published: March 2020

El presente artículo constituye un intento de análisis sobre las prácticas localizadas de la sexualidad masculina, extrapolando dos espacios en particular, por un lado los templos Moche, y por otro, los chicheríos de la costa norte, a partir de la identificación de ciertos elementos de análisis, los cuales configuraría una propuesta epistemológica que nos permitiría identificar ciertas permanencias como transformaciones operadas en las interacciones entre el sujeto masculino y su otredad. Además, el artículo propone una reflexión acerca de la auto-etnografía como método de acercamiento a la realidad, teniendo como base la experiencia y el conocimiento corporeizado/localizado. Es importante mencionar que el artículo es una primera aproximación, el cual es un trabajo que ha ido avanzando paso a paso, primero encontrando y analizando la evidencia arqueológica/material e historiográfica, para luego introducir las categorías y esquemas más sociológicos y antropológicos. Sabemos que el artículo tiene aún temas que desarrollar y profundizar, los cuales intentamos sistematizar en las conclusiones como potenciales temas a continuar.

The Logical Basis of a Literary Text, or What Does Porfiry Petrovich Hide in F. M. Dostoevsky’s “Crime and Punishment”?
Authors: Vetlovskaya Valentina E.
Published: March 2020

The article explores the role of logical connections in an epic text. It is these connections, according to the author of the article, that connect the individual components of the narrative (motifs, complexes of motifs) and make up in the reader’s perception for the missing elements. The reticence and failures to mention, common in fiction, appear in the narrative for various reasons. Sometimes due to the aesthetic principles of the writer who prefers ambiguity to a completed statement depriving readers of the opportunity to finish thinking over a vague idea. And sometimes, due to the author’s conviction that there is no need to explain the idea implied by what has been earlier said. But it also happens that the omissions in the narrative are engendered by the requirements for the presentation of a chosen topic, for example in crime fiction. But these reasons may go together as it occurs in Crime and Punishment. These ideas are illustrated by the analysis of one of the themes of the novel Crime and Punishment.
Revisiting to the Geiger–Nuttal Relation to be Employed in the Estimation of the Half-Lives of Superheavy Nuclei
Authors: Al-Jomaily F. M. A. , Khalil M. I.
Published: March 2020

The half-lives for the even–even (e–e), even–odd (e–o), odd–even (o–e) and odd–odd (o–o) nuclei in the range 100 < Z < 120 have been tested within the Viola–Seaborg formula (VSF) and within the analytical formula of Royer (RF). We proposed another formula (Present Work Formula or PWF) with regard for the effect of angular momentum of the alpha decay particle and with the use of the relative neutron excess (︀(N−Z)/A)︀. Our formula includes a new set of parameters found by the least square fitting method of alpha decays of 128 nuclei. We obtained the standard deviations for each of the formulas for comparison. The results show an acceptable agreement with available data. The values of the suggested theoretical coefficient (K) for the PWF show a similar behavior of half-lives with a-decay, which can be used to predict the new superheavy nuclei.

Published: March 2020

The influence of the atomic disorder on the Auger recombination rate in p-InGaN alloys has been studied. The disorder was simulated using a 4 × 4 × 4 supercell in which In and Ga atoms taken in a required stoichiometric ratio were randomly distributed over the supercell sites. A comparison between the Auger recombination rates calculated in the framework of the supercell and virtual-crystal approximations showed that a large number of allowed interband transitions induced by the atomic disorder strongly increases the Auger recombination rate in wide-band-gap p-InGaN alloys.

Authors: Debelo N. G. , Hailemariam S.
Published: March 2020

The effect of thermal annealing on thermoluminescence (TL) glow curves of commercially obtained KY3F10:Ho3+ phosphor is investigated, and the result is compared with that of unannealed sample. The samples were annealed at different annealing temperatures: namely, 400, 500, and 600 ∘C. The activation energy (trap depth), which is one of the TL kinetic parameters, is calculated for the annealed and unannealed samples using the variable heating rate (VHR) method. The results show that the thermal annealing has a clear effect on the TL intensities of the glow curves. The maxima of the TL glow curves shift toward a higher temperature region, as the annealing temperature increases. Moreover, the higher the annealing temperature, the shallower the position of the trap beneath the edge of the conduction band. The X-ray diffraction (XRD) pattern of the sample shows a monoclinic structure with unit cell dimensions (in Angstr¨om) a = 10.41, b = 6.73, c = 12.46 match with JCPDS card No. 21-1458.
Goodness of Generalized Seniority in Even-even Sn Isotopes.
Authors: Bhoomika Maheshwari
Published: March 2020

Seniority has proved to be a unique and simple probe to address some of the complex issues underlying nuclear structure of nuclei close to magic numbers. An extension from the concept of seniority in single-j shell to generalized seniority in multi-j shell has recently been provided by us. We have, consequently, established new selection rules for gamma decays and discovered the new seniority isomers decaying via odd electric multipole operators. We have successfully explained the B(EL; L=1,2,3) behavior of various high spin isomers and other excited states. More specifically, we have been able to explain the long-standing puzzle of double hump in the B(E2) values for the first excited 2+ states of even-even Z=50 (Sn) isotopes. In the present paper, we review these generalized seniority calculations with emphasis on even-even Sn isotopes. We first discuss the generalized seniority results for the E1 decaying 13- isomers and E2 decaying 10+, 15- isomers, and then present the cases of first-excited 2+ and 3- states. The generalized seniority proves out to be a reasonably good quantum number. The significance of configuration mixing is found to be true. The calculated results has been validated till high seniority v=4 states and expected to be valid for higher seniority v=6,… states also.

Published: March 2020

Thermal neutron flux (Фth) of Americium-Beryllium (Am-Be) neutron source has been measured by adopting the foil activation method. The neutrons emitted from Am-Be source are used to activate the indium-115 (115In) foil. The gamma radiations emitted from the activated isomer 116m1In are measured with NaI(Tl) and HPGe detectors. The thermal neutron flux is measured by adopting the cadmium (Cd) foil difference technique in which the Cd foil placed in front of the source to prevent the thermal neutrons from entering into the indium foil. The neutron flux is determined by measuring the gamma radiation emitted from indium foil using a low and high energy resolution NaI(Tl) and HPGe detectors respectively. The measured thermal neutron flux obtained from both detectors has been compared and found that the Фth does not depend on the resolution and type of the detectors used in the present investigations.

Herbicides with 2,4-dichlorophenoxyacetic acid (2,4D) has been commonly used to control weeds and widely detected in environments. In this study, biodegradating activity of Pseudomonas fluorescens HH on 2,4D and 4-chlorophenol (4CP) in soil was carried out. The inoculation with Pseudomonas fluorescens HH in soils increased the degradation of 4CP and 2,4D by from 47.0% to 51.4% and from 38.4% to 47.4%, respectively, compared to the degradation by autochthonous microorganisms. Pseudomonas fluorescens HH could degrade well 2,4D and 4CP in various soils, but the most efficient chemical removal was observed when they were in the loamy soil. Moreover, the efficiency of chemical degradation was significantly affected by the moisture contents with the highest performance of degradation at 10 and 20% soil moisture. Also, the addition of nitrogen (N), phosphorous (P) and potassium (K) stimulated the dissipation rates. The determination of degradation pathway for 2,4D in Pseudomonas fluorescens HH indicated that 2,4-dichlorophenol (2,4DCP) and 4CP were formed as metabolites.

New records of  Hipposideros griffini  from lava caves and the threats to its conservation in Vietnam
Authors: Thong Vu Dinh
Published: March 2020

Lava caves are unique and fragile ecosystems which are suitable for a wide variety of plant and animal species. However, the biodiversity of lava caves is still poorly studied. To increase knowledge of these special ecosystems, several rapid surveys on bats were carried out in Dak Nong Province in sounthern Vietnam between 2014 and 2019. Bats were captured in the field using mist nets and harp traps. Echolocation calls were recorded in different situations using the PCTape system. The results include records of Griffin’s leaf-nosed bat (Hipposideros griffini) which is regarded as a species endemic to Vietnam only. Prior to the present study, it was only recorded from karst and moutain habitats in three different regions of Vietnam: Cat Ba National Park in the northeast, Chu Mom Ray in the central highlands, and Cat Tien National Park in the southeast. Records of Hipposideros griffini from Dak Nong Province extend its distributional range and highlight the importance of lava cave systems for biodiversity research and conservation in Vietnam. Griffin’s leaf-nosed bat and other animal species inhabiting the lava caves have been critically threatened by hunting and other human activities. Morphological measurements  and echolocation calls of Hipposideros griffini together with the threats to its conservation status in Dak Nong Province are given in this paper.

Mangroves are the most productive ecosystems and contain highly diverse plants and microbial communities. Mangrove endophytes are proved to be a rich source of bioactive secondary metabolites. The biological molecules produced by endophytes play an important role in protection of mangrove plants against herbivores, insects as well as pathogens. The present study aimed to isolate the endophytic bacteria from the mangrove plant Rhizophora stylosa and screen antimicrobial and antioxidant activity of ethyl acetate extracts from the isolated endophytic bacteria. A total of 64 endophytic bacterial strains from R. stylosa leaves were isolated, of which ethyl acetate extracts of 14 isolated endophytic strains showed antimicrobial activity against at least one of reference microorganisms Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 25923, Bacillus subtilis ATCC 27212, Staphylococcus aureus ATCC 12222 and Candida albicans ATCC 7754 with MIC values from 32 to 512 µg/ml. Among them, four strains showed activity against one reference microorganism, five strains showed activity against two reference microorganisms, four strains showed activity against three reference microorganisms, and one strain showed activity against four reference microorganisms. Additionally, the ethyl acetate extracts of 12 isolated endophytic bacteria showed ATBS and DPPH radical scavenging activity with scavenging values from 36.27 ± 2.6% to 71.46 ± 6.6% and from 26.22 ± 3.3% to 57.38 ± 5.8%, respectively. The identification of the five most active endophytic bacteria by 16S rRNA sequences revealed that the endophytes belonged to four genera, including Bacillus, Streptomyces, Pseudovibrio and Pseudomonas. The obtained results suggest that the endophytic bacteria from mangrove plants are a promising reservoir of antimicrobial and antioxidant agents.

Long-nosed fruit bat is a common name of the genus Macroglossus which comprises two species: Dagger-toothed long-nosed fruit bat (M. minimus) and Greater long-nosed fruit bat (M. sobrinus). These two species were rarely recorded from Vietnam or neighboring countries. Within Vietnam, M. minimus has been recorded only from two localities in southern Vietnam while M. sobrinus was known from all northern, central and southern regions of the country. Morphological features of these species in Vietnam were poorly documented in previous publications. With results from a rapid examination of all specimens and recently captured individuals, we here confirm that M. sobrinus is distinctively larger than M. minimus in all external and craniodental measurements. Two species are also distinguishable by their nostril shapes and mandible symphyses. This paper provides new distributional records of both M. sobrinus and M. minimus from Vietnam with remarks on their ecology and habitats.
