Studies on polymorphism of enzyme systems in populations of Apis florea F. (Hymenoptera: Apidae) from Chandigarh and foothills of Himachal Pradesh, North West India
Authors: Kumar Rajeev , Kaur Jaspreet , Kumar Neelima R 
Published: July 2019

Biochemical characterization and enzyme polymorphism are useful tools in establishing intraspecific diversity in insect populations. The populations of Apis florea F. adult workers were selected from six varied topographic and climatic places of north western India including Chandigarh plain and foothills of Himachal Pradesh. These honey bees were analysed for proteome profile by SDS-Polyacrylamide gel electrophoresis (PAGE). Further four enzyme systems namely malate dehydrogenase (MDH), alcohol dehydrogenase (ADH), esterase (EST) and hexokinase (HK) were analysed for enzyme polymorphism and isozymic variability in all the populations by running native PAGE and staining with specific substrate stains on the gels. Sixteen protein bands were reported in each population of A. florea using SDS PAGE and no difference was found in banding pattern of proteins of the populations studied. Enzymes stained on native PAGE from whole body homogenates revealed single isozymic form of ADH, two isozymic forms each of EST and MDH and three isozymic forms of HK in all the populations of A. florea collected from different study regions. There was significant difference in specific activity of enzymes from different regions but no polymorphism was found for the enzymes studied. Small changes in Rf values were found in the isozymes of the enzymes. The results suggest that none of these enzyme systems could be used as marker to differentiate the species at intraspecific level as the enzyme MDH, ADH, EST and HK did not exhibit polymorphism in A. florea from studied regions. In conclusion a single species of A. florea persisted throughout the area studied. However the slight changes in mobilities of individual bands and also changes in specific activity of enzymes reflect the adaptation ability of the bee according to climate variations.

Effect of coriander Coriandrum sativum L. on parasitization behaviour of Trichogramma chilonis Ishii (Trichogrammatidae: Hymenoptera) in brinjal ecosystem
Authors: Manoj P. Dominic , Ravi G. 
Published: July 2019

For the management of the brin-jal shoot and fruit borer augmentatory biocontrol using Trichogramma chilonis Ishii egg parasitoid is a viable option. Experiments conducted in the net house (pro tray technique) and field to study the effect of coriander on the parasitization, revealed that under free choice test, maximum numbers of parasitized eggs were observed in brinjal grown with coriander at 1:1 ratio (29.48 eggs/ card). Under no-choice condition the mean number of parasitized eggs recorded was 20.88 eggs per card observed in brinjal. In the field experiment using sentinel egg card technique no statistical difference in parasitoid performance between the sole crop and intercropped plot was observed. In this studies (field experiments) clearly indicate that there is no significant effect of coriander on parasitisation of T. chilonis, though the results were promising in the green house. The probable reason for this may be due to influence of climate factors like wind direction, temperature and RH.
First record of body colour polymorphism in giant African snail Achatina fulica (Bowdich, 1822) - a comparative study using mitochondrial cytochrome oxidase subunit I (COI) gene
Authors: Vijayan Keerthy , Sakthivel R. Sugantha , Sajeev T.V. 
Published: July 2019

The presence of the body colour polymorphism in the tropical invasive pest giant African snail is reported for the first time from South India. Three different body colour polymorphs were recognised viz. grey, black and white. The grey body colour is the most common polymorph. The black and white colour polymorphs are found to be in almost equal proportions in the reported localities with the grey counterparts. The cytochrome oxidase subunit I (COI) sequences of the three colour polymorphs are found to be identical. The presence of the body colour polymorphism in south India may be attributed to the avian predation and other selection pressures.

Published: July 2019

The possibility of using N-allylcarbothioamide derivatives as well as products of their iodine- and proton-initiated electrophilic heterocyclizations as chelating agents in complexation reactions with Zn(II) and Ag(I) ions is shown. Processing of the obtained experimental data showed that N-allythioamides of pyrimidinyl (cyclohexenyl) carboxylic acids H2L1 – H2L3 and their proton- and iodo-cyclization products HL4, HL5 containing four nucleophilic reaction centers (two oxygen atoms of the carbonyl and hydroxyl groups and N-, S-carbothioamide groups or N-atoms of the dihydrothiazole moiety) are polydentate ligands capable of coordinating with metal ions to form stable six-membered chelate metallocycles.
A series of new chelating mono-, bi- and polynuclear complexes Zn(II) and Ag (I) of the composition [Zn2L1,32]n, [Zn2(HL1-3)2(CH3COO)2], [Ag2(HL1,3)2]n, [Zn(HL1-3)2], [Ag(H2L3)2NO3], [Zn(HL4,5)2], K[Ag(HL4,5)2] were synthesized and isolated in solid state. Their molecular structure was established by methods of elemental chemical analysis, NMR 1H, IR and UV-Vis spectroscopy.
At a ratio of M:L 1:2, complexes were isolated in which two ligand molecules H2L1 − H2L3 are coordinated to the metal ion by the sulfur atoms of the carbothioamide group and the oxygen of the mono-deprotonated hydroxyl group. It was established that the products of the proton-/iodocyclization HL4, HL5 in the complex formation pass into the thione tautomeric form with coordination through the oxygen atoms of the deprotonated hydroxyl group and nitrogen atoms of the dihydrothiazole heterocycle. At M:L 1:1, binuclear or polynuclear coordination compounds are formed. It was shown that polymerisation in complexes [Zn2L1,32]n and [Ag2(HL1,3)2]n is due to the formation of Zn−(O2SN)−Zn and Ag−O−Ag polymer chains.
Investigation of the solubility of the resulting complexes showed that the polymer complexes are weakly soluble or insoluble in DMSO, DMF, while the mononuclear are soluble in methanol, as well as in water.

Published: July 2019

A series of N-acyl derivatives of anthranil (or o -aminobenzoic acid) was first synthesized, namely 2-(4-octylbenzamido)benzoic acid, 2-(4-(heptyloxy)- benzamido)benzoic acid, 2-(4-(heptylsulfanyl)benz-amido)benzoic acid. 2-(4-octylbenzamido)benzoic acid was synthesized in five stages of octylbenzene, by acylating chloride acid using a Friedie-Crafts reaction. 2-(4-(heptyloxy)benzamido)benzoic acid was prepared from the methyl ester of p-hydroxybenzoic acid which, at the first stage, was activated with 1-bromoheptane in acetonitrile with potassium carbonate and catalytic amount of sodium iodide at heating. After that, hydrolysis of the ester group by hydroxide in the methanol–water system was performed. Synthesis of 2-(4-(heptylsulfanyl)benzamido)benzoic acid was carried out from p-sulfanylbenzoic acid, which was activated with 1-bromoheptane, in a system of ethanol–water with sodium hydroxide. Chlorinated hydrides of acids were obtained by reaction of acids with chlorinated thionyl in benzene. Acylation of the tret-butyl ester of anthranilic acid with formed chlorohydrides was carried out in pyridine upon heating and in dichloromethane with triethylamine (as the base), and dimethylaminopyridine (catalyst).At the last stage of the synthesis of all derivatives, the hydrolysis of tret-butyl esters with trifluoroacetic acid in dichloromethane to the formation of terminal compounds took place.The composition and structure of the synthesized compounds were determined using NMR 1H, infrared spectroscopy. The shape and position of the bands in the IR absorption spectra of the synthesized anthranilic acid derivatives are shifted and splited in comparison with the parent acid due to the presence of a secondary amino group, an additional aromatic moiety, and a different nature of the substitutes in the para-position to the amino group. For all synthesized derivatives, the sensitivity of various morphological forms Candida albicans was determined. The influence of the test substances on the cells of the yeast fungus was determined for 24–48 hours using Saburo and Spider nutrient media with the addition of mannitol. Compared with the already known influence of anthranilic acid on Candida albicans cells grown in Saburo nutrient medium for 24 hours, the compounds studied were more effective at all stages of cultivation. It has been shown that the synthetic derivatives studied are more active with respect to the cells in the biofilm composition, which consists of the yeast-like form of Candida albicans, than those cells that form a hyphal type biofilm. The yeast-like form of the Candida albicans cell is susceptible to synthetic derivatives. It is shown that the level of sensitivity of compounds 1-3 is higher in 4-6 times compared with anthranilic acid. Glyphs have been found to be more susceptible to the effects of the compounds studied than Е yeast cells of Candida albicans
OLIGOMERIC SILSESQUIOXANES COMBINING AZO- AND FLUORESCENT DYES IN ORGANIC SHELL

Published: July 2019

A method for the synthesis of reactive oligomeric silsesquioxanes, combining fragments of azo dye 4-(phenylazo)phenol and fluorescent dye Rhodamine B in various proportions in an organic shell was developed. These compounds were obtained by the reaction between the oligosilsesquioxane nanoparticles consisting of a mixture of linear, branched, ladder and polyhedral structures with epoxy groups in an organic frame (OSS–Ep) and the dyes. The structure of the synthesized substances was characterized by the methods of IR and 1H NMR spectroscopy. The UV-Vis spectra of OSS–Pp–Rh in DMF solution contain absorption bands characteristic of both acidic (560 and 350 nm) and lactone (in the range of 318–326 nm) forms of Rhodamine B. The absorption band of 4-(phenylazo) phenol fragments corresponding to π−π* transition is observed at 348 nm and overlaps the absorption band of Rhodamine B at 350 nm.The intensity of the absorption bands of fragments of various dyes depends on their content in organic frame of the silsesquioxane core. The intensity of the absorption bands at 348 nm and at 560 nm increases with an increase in the content of 4-(phenylazo)phenol and Rhodamine B correspondingly.It should be noted that when using DMF as a solvent the absorption band corresponding to acidic form of Rhodamine B at 560 nm in the UV-Vis spectra of the compounds obtained is more intense than similar band in the spectrum of the original Rhodamine B. Therefore, the attachment of Rhodamine B to the silsesquioxane core of oligomeric silsesquioxanes mixture does not have a significant effect on the position of absorption maxima in the UV-spectrum and prevents dye’s fragments from converting to the colorless lactone form. In the fluorescence spectra of OSS–Pp–Rh obtained using DMF as a solvent a peak at λ max = 592 nm (λex= 520 nm) is observed. The position of the fluorescence peak and its intensity in the spectra at the same optical density of the medium practically do not depend on the ratio of fragments of 4-(phenylazo)phenol and Rhodamine B in organic frame of OSS–Pp–Rh. The combination of two different chromophores in organic shell of the silsesquioxane core broadens the range of absorbed light and the change of their ratio allows to adjust the absorption intensity in a certain area. The presence of hydroxyl groups makes it possible to introduce the obtained compounds into the composition of polymeric organic-inorganic nanocomposites by covalent bonding.

Published: July 2019

A sodic non-ferrous stilpnomelane, which has the radiocristallographic properties of natural stilpnomelane, has been synthetized : 1) From amorphous materiel (gels) at P = 2 kbars and T = 650° C. Experiments of two months were necessary for crystallization. The influence of temperature and time on the appearance of stilpnomelane and on paragenetic relations of stilpnomelane, chlorite, paragonite, talc, saponite, Na-hectorite phases and their interstratifications was studied. 2) From precrystallized synthetic magnesian chlorite + albite mixture at P = 2 kbars and T = 630° C (t = 1 month). The similarities with natural stilpnomelanes are discussed.
Sur une allanite filonienne, à Bramans en Maurienne (Alpes occidentales, Savoie)
Authors: Bocquet Jacqueline 
Published: July 2019

Une veine comportant de l'allanite, de l'albite et de l'hématite a été découverte au sud du massif de la Vanoise, dans une lentille schisto-gréseuse métamorphique, englobée dans des gypses triasiques. Les caractères optiques, radiocristallographiques et chimiques de l'allanite sont donnés. La distribution des terres rares traduit une concentration relativement faible en terres rares légères. L'association hydrothermale du filon distingue ce gisement d'allanite des autres connus dans les Alpes. Son âge et son origine ne sont pas déterminés : la cristallisation pourrait être alpine, permienne ou plus ancienne et résulter du remaniement d'un dépôt antérieur ou être liée à des granitoïdes et un métamorphisme soit permiens, soit antérieurs.
Eléments pour une histoire du peuplement nord-alpin français entre 10000 et 2700 ans BP

Published: July 2019

Depuis plus de 30 ans, dans les massifs montagneux des Alpes françaises du Nord, des programmes de recherche ont renouvelé nos connaissances sur des occupations humaines de la Préhistoire récente. Des gisements ont livré des séquences chrono-culturelles et naturelles de référence. Bien calées chronologiquement, elles autorisent une bonne approche des évolutions culturelles, du Mésolithique moyen à la fin de l 'âge du Bronze, ainsi que bioclimatiques, du Préboréal au début du Subatlantique. Pour répondre à des problématiques d'occupation des territoires, des prospections thématiques ont été mises en œuvre par des chercheurs d'horizons différents ; quelques-uns contribuent ici à cet échange de données.
Retracer les épisodes du peuplement préhistorique dans un espace ouvert aux influences aussi vaste et sur un temps aussi long n 'étant pas possible dans cette contribution, il est proposé de porter un regard documentaire sur trois secteurs géographiquement individualisés et bien caractérisés géomorphologiquement :
-dans les domaines lacustres savoyards, dans l 'Avant-Pays au contact du Jura méridional, les principaux épisodes de l 'occupation littorale sont présentés (abattages dendrochronologiques entre les années 3842 et 805 av. J.-C.) ;
-dans les massifs subalpins calcaires de moyenne altitude, Chartreuse et Vercors, proches des grands axes de circulation (sillon alpin, couloir rhodanien), les modalités de passage du Mésolithique moyen alpin (de 8000 à 7000 av. J.-C.) au début du Néolithique moyen (de 4800/4700 à 4500 av. J.-C.) sont exposées ;
-dans la zone montagneuse orientale cristalline d'altitude plus élevée, les travaux menés dans les hautes vallées de Maurienne et de Tarentaise montrent la précocité et l 'intensité des conquêtes néolithiques.
Une nouvelle approche du système des lapiés alpins nus
Authors: Tóth Gábor 
Published: July 2019

Afin d'étudier le développement des surfaces lapiazées, un nouveau système des lapiés nus des hautes montagnes a été crée pour lequel il nous a fallu utiliser d'anciennes classifications. Pour la construction du système certaines notions ont été redéfinies : cellule lapiazée, unité lapiazée et complexe lapiazé. Cette classification est constituée par quatre niveaux qui sont : les formes individuelles, les formes complexes, la cellule lapiazée et le champ de lapiés.
Les cellules lapiazées ont été regroupées et classées selon des mesures effectuées dans différentes zones calcaires des Alpes. Les aspects de la typologie sont le mode de séparation de leur environnement, leur morphologie, l 'état avancé de leur développement et leur structure.
En examinant la morphogenèse des cellules hétérogènes, nous pouvons considérer que l 'ensemble des formes se développent selon deux phases. Dans la première, nous trouvons un facteur déterminant (par exemple l 'angle d 'inclinaison ou la structure de la roche) qui influence la formation des premiers lapiés. Par la suite, les formes primaires modifient l 'écoulement sur la surface ce qui permet un développement des formes secondaires.
Parc et thermalisme en milieu transfrontalier : influences et dissemblances dans un contexte franco-allemand
Authors: Beaudéan Colette 
Published: July 2019

L'utilisation des eaux minérales et thermales est à la source d'une architecture typique dont les parcs et les jardins ont été des pièces maîtresses. Ils permettent de renforcer les effets de la cure grâce aux promenades que l 'on y effectue tout en favorisant les rencontres. Ils participent aussi à l 'embellissement et à l 'aération de la ville.
La station de Baden-Baden (Bade-Wurtemberg) s 'est dotée de jardins et de promenades dès le XVIIe siècle ; la Lichtentaler Allee, bordée de chênes est restée, au fil des siècles, le joyau de la station. A cinquante kilomètres de là, Niederbronn (Bas-Rhin) s 'efforça de rivaliser avec Baden-Baden en s 'ornant de parcs arborés et en aménageant sa forêt communale pour les excursions des curistes.
Mais depuis le milieu du XXe siècle, les destins des deux stations ont divergé. A Baden-Baden, les parcs ont conservé tout leur éclat, alors qu'à Niederbronn, les jardins sont affectés par le déclin thermal. Aujourd'hui, il en résulte un contraste fort entre les deux stations.
Les grottes, éléments du patrimoine des stations thermales : le cas d'Aix-les-Bains
Authors: Gauchon Christophe 
Published: July 2019

Dans le thermalisme tel qu 'il s 'est développé au XVIIIe et au XIXe siècles, les grottes ont souvent joué un rôle important pour la récréation pour les curistes ; les grottes constituaient autant d 'éléments du patrimoine paysager mis en valeur et proposés à la visite. Et tel fut en particulier le cas à Aix-les-Bains dont le riche environnement était largement mis à contribution.
Ainsi, autour d'Aix et au cœur même de la station, quatre grottes ont-elles été associées à l'activité thermale. Il s 'agit de la grotte Raphaël associée au souvenir lamartinien, de la grotte des Serpents située derrière le bâtiment des thermes, de la grotte de Banges (dans les Bauges) et de la grotte des Fées, au-dessus de Saint-Innocent.
La grotte des Serpents s 'avère ici la plus riche en termes de patrimoine : les Archives départementales de la Savoie recèlent un épais dossier relatant les détails d'une affaire judiciaire qui se noua autour des grottes dans les années 1855-56. Joyaux de cet épais dossier, des plans des grottes furent levés pour éclairer les revendications des différentes parties. Au-delà de leur intérêt judiciaire, ces plans colorés sont d'une précision et d'un rendu étonnant et constituent à eux seuls un patrimoine exceptionnel.
Cambiar el Poder Judicial: el modelo acusatorio y el juicio por jurados como ejes para una reforma necesaria
Authors: Eissa Sergio Gabriel , Guerra Patricia , Urrutia Pablo , Garro Lautaro 
Published: July 2019

El Poder Judicial transitó sin cambios estructurales desde su conformación a mediados del Siglo XIX. Sin embargo, los elevados índices de reincidencia criminal, el aumento de la población carcelaria, y la extensa duración de los procesos judiciales han dejado al descubierto el desplome del sistema de justicia.
Este artículo sostiene que el actual modelo de justicia no responde a los estándares de calidad, transparencia y eficiencia ni al mandato constitucional. A los efectos de superar esta situación se considera necesario realizar una reforma que implemente un servicio de justicia democrático. En tal sentido, el trabajo se pregunta: ¿en qué consistiría éste? Para ello, se organiza en dos grandes apartados. El primero analiza el surgimiento histórico del modelo acusatorio y el juicio por jurado, elementos claves para esta reforma. El segundo repasa el debate sobre el Poder Judicial en la teoría política y durante la Asamblea Constituyente de 1853.
El vínculo político de los músicos independientes de rock en el Partido de Avellaneda (desde 2016 hasta 2018)
Authors: Saponara Spinetta Valeria Lucia 
Published: July 2019

La ciudad de Avellaneda (zona sur del conurbano bonaerense, Provincia de Buenos Aires –Argentina-), se caracteriza por las políticas e instituciones culturales activas e inclusivas y la variada oferta cultural. La gestión municipal actual -cuyo intendente desde 2009 responde al Frente para la Victoria-, se distingue, además, por la amplia oferta de espacios culturales y por promover la participación ciudadana.
La actividad musical independiente suele realizarse en condiciones materiales desfavorables, las cuales empeoraron luego de la Tragedia de Cromañón. Desde entonces, muchos músicos independientes se agruparon y organizaron en pos de obtener políticas que mejoren y fomenten la actividad musical.
El objetivo de este artículo es analizar el vínculo político que asumen los músicos independientes de rock en Avellaneda. A través de un abordaje cualitativo se trabajó con entrevistas, observación participante y notas y artículos periodísticos.
Se observa que los músicos independientes entrevistados valoran positivamente la política cultural del municipio.
Resumen: Consumos problemáticos juveniles, trayectorias y subjetividades
Authors: Barrenengoa Pablo David 
Published: July 2019

Esta tesis se propone indagar trayectorias y subjetividades de jóvenes que desarrollan consumos problemáticos de sustancias psicoactivas, a partir del análisis de ocho historias de vida de jóvenes varones internados en una comunidad terapéutica del Gran La Plata. En este marco, se abordan los consumos problemáticos desde una mirada que pondera la pluralidad de sentidos y relaciones que pueden establecerse con las sustancias, inscribiendo la perspectiva de análisis dentro de un campo de problemas de la subjetividad.
Los hallazgos principales de este estudio analizan la función de las sustancias en los ritos de pasaje juvenil, las lógicas que subyacen a sus procesos de subjetivación, el rol de los grupos de pares, los imperativos de consumo y masculinidad como micropolíticas de subjetivación y aspectos identitarios vinculados al mundo del consumo.
