Theory of g-Tg-Exterior and g-Tg-Frontier Operators: Definitions, Essential Properties and, Consistent, Independent Axioms
Authors: Khodabocus Mohammad Irshad , Soolia Noor-Ul-Hacq
Published: March 2020

In a generalized topological space Tg = (Ω, Tg), generalized interior and generalized closure operators g-Intg, g-Clg : P (Ω) −→ P (Ω), respectively, are merely two of a number of generalized primitive operators which may be employed to topologize the underlying set Ω in the generalized sense. Generalized exterior and generalized frontier operators g-Extg, g-Frg : P (Ω) −→ P (Ω), respectively, are other generalized primitive operators by means of which characterizations of generalized operations under g-Intg, g-Clg : P (Ω) −→ P (Ω) can be given without even realizing generalized interior and generalized closure operations first in order to topologize Ω in the generalized sense. In a recent work, the present authors have defined novel types of generalized interior and generalized closure operators g-Intg, g-Clg : P (Ω) −→ P (Ω), respectively, in Tg and studied their essential properties and commutativity. In this work, they propose to present novel definitions of generalized exterior and generalized frontier operators g-Extg, g-Frg : P (Ω) −→ P (Ω), respectively, a set of consistent, independent axioms after studying their essential properties, and established further characterizations of generalized operations under g-Intg, g-Clg : P (Ω) −→ P (Ω) in Tg.

Authors: Hassan Sk Sarif , Kumar Rout Ranjeet , Sharma Vipul
Published: March 2020

In 2020, the pandemic caused by the Coronaviruses (CoV) that are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV2). The Coronavirus disease (COVID-19) is a new strain that was discovered in 2019 and has not been previously identified in humans. It is the high time to investigate the quantitative and/or qualitative genomic informations of the virus SARS-CoV2 in order to strengthen the healthcare facility to fight against this viral disease. In this article, a through quantitative understanding of the purine and pyrimidine spatial distribution/organization of all 89 complete sequences of SARS-CoV (available as on date in the NCBI virus database, is made using different parameters such as fractal dimension, Hurst exponent, Shannon entropy and GC content of the nucleotide sequences of the genome of SARS-CoV2. Also a cluster among all the the SARS-CoV sequences of nucleotide have been made based on their phylogeny made through their closeness (Hamming distance) based on respective purine-pyrimidine distribution.
The Role of International Educational Exchange in Turkish Foreign Policy as a Reconstructed Soft Power Tool
Authors: KELKİTLİ Fatma Asli
Published: March 2020

International educational exchange has been used frequently as a foreign policy instrument by leading actors of the international arena since the post-Second World War years. This article on the other hand, aims to throw light on the policies and actions of a middle power; namely, Turkey, which has been designing various international scholarship programs for foreign policy ends since the early 1990s. Following a brief evaluation of the international educational exchange programs launched by the USA, Russia, the UK, the EU and China for foreign policy purposes, the study examines the Great Student Exchange Project introduced by Turkey in 1992 to carve out an influential place for itself in the South Caucasus and Central Asia. It will then delve into the Türkiye Scholarships Program, Mevlana Exchange Program and the scholarship programs of the Türkiye Diyanet Foundation, which have been introduced during the Justice and Development Party period to build up and/or boost friendly ties between Turkey and various targeted countries. The study finalizes by investigating the impact of these scholarship programs on the realization of Turkey’s foreign policy goals by exploring to what extent the sending countries align their foreign policy preferences with those of Turkey through analysis of their voting behaviours in the United Nations General Assembly.

Les formations a stromatolithes dans le Sahara occidental
Authors: Menchikoff Nicolas
Published: March 2020

Dolomitic limestones containing abundant stromatolites at the base of the Paleozoic sedimentary series of the Taoudenni syncline in the western Sahara (French West Africa) are Cambrian in age. The stromatolites are calcareous concretions whose formation was due to the action of algae and possibly also of bacteria. In the case of Collenia, genera and species refer to the structure formed, not to the organism responsible for the formation. Forms assigned to Conophyton exhibit a regularity indicating a homogeneous group, which may be of stratigraphic significance.

Gres du flysch; quelques observations tirees d'une etude comparee du flysch carpatique, pyreneen et alpin
Authors: Rech-Frollo Marguerite
Published: March 2020

A comparative petrographic study of Flysch deposits of the Carpathians, Pyrenees, and Alps shows that they exhibit diagnostic sedimentational features, which differ from those of other marine sediments and from present-day oceanic deposits. This is particularly true of the sandstones, which are marine deposits containing fluviatile elements. Because of the unworn character of the detrital material and the absence of sorting in the beds, the sandstones are considered to be the product of rapid deposition of detritus which invaded a marine basin.

Note preliminaire sur le Carbonifere de l'Ahnet et du Mouydir (Sahara central)
Authors: Follot Jacques
Published: March 2020

In the Ahnet-Mouydir region, Algeria, of the central Sahara, the Dinantian (Carboniferous) is represented by a thick series of shales and sandstones. Thin limestones intercalated in this series bear a very rich fauna of goniatites and brachiopods, which is listed. Dark slates overlying limestones bearing Productus giganteus probably represent the Namurian. Continental red beds with plant remains discordantly overlying the Dinantian are probably upper Carboniferous. From south to north, the facies pass from littoral sediments to limestones; from west to east, there is evidence of several temporary emergences, testifying to the unstable regime of the eastern Sahara during the Carboniferous.

Contribution a la connaissance du Pliocene du bas Rhone
Authors: Bonnet Andre , Duboul-Razavet Christiane
Published: March 2020

Data from deep borings indicate that the Pliocene sedimentary cycle in the lower Rhone region, France, was characterized by an extensive marine transgression which drowned an accentuated topography and formed a fairly deep and stable sea in Oligocene depressions. Fine sediment was deposited under reducing conditions. The cycle terminated with marine deposition under oxidizing conditions, which was followed by lagoonal, then by coarse terrestrial sedimentation. The Pliocene formations have been dislocated by recent movement.

Foraminifers belonging to the genus Spirocyclina, probably S. infravalenginensis, were encountered in the course of drilling in the Paris basin, France. The accompanying macrofauna and ostracods indicate a Portlandian (Jurassic) age for the enclosing beds.
Etude hydrogeologique de quelques plaines de la Turquie
Authors: Fournier Hugo G.
Published: March 2020

Describes the geology and ground-water possibilities of four alluvial plain areas in Turkey, two of which are located along the Syrian border, the other two on the Anatolian plateau. The plain areas of the Syrian border region are composed of Cretaceous and Tertiary marine sediments capped by Quaternary alluvium and, in places, volcanic flows. Water-bearing sequences of alternating permeable limestones and impermeable marls may be present. The ground-water possibilities of the plateau plains, composed of Tertiary lacustrine and volcanic beds capped by Quaternary alluvium and lava, are less favorable.
Remarques sur quelques hypotheses recentes de tectonique algerienne
Authors: Flandrin Jacques
Published: March 2020

Takes exception to certain nappe structures which have recently been postulated in the literature for the central Tell region, Algeria, and outlines the structural development of the region relative to the effects of tectonic landslides, gravitational flow, and other deformational processes.
La geologie de l'Himalaya de l'Arun
Authors: Bordet Pierre , Latreille M.
Published: March 2020

Presents stratigraphic and structural details of the Arun valley in the Himalayan range (eastern Nepal) as a supplement to data in previously published papers. The formations of the Ganges plain are probably Quaternary; the Dharan series is comparable to the middle Siwalik beds, dated as lower Miocene; the Sangouri series is Permo-Triassic; the sedimentary cover of the lower zone includes Cambrian to Carboniferous strata, and the underlying migmatites are then Precambrian; in the high peaks, the Everest series probably represents the base of the Paleozoic, and the underlying Barun gneiss is therefore probably Precambrian. Structures include an east-west system of faults and transverse north-south folds. Rapid uplift is actually taking place along the south border of the range.
Les clypeines (algues siphonees verticillees) des monts des Oulad-Nail, Atlas saharien, Algerie
Authors: Emberger Jacques
Published: March 2020

Describes the occurrence of the alga Clypeina in Jurassic and Neocomian (Cretaceous) deposits of the Oulad-Nail mountains in the Saharan Atlas, Algeria, and the distribution of the species C. jurassica. Among the Valanginian species, two are new: C. lucasi and C. marteli.
Sur la classification du Miocene superieur continental de la vallee du Rhone
Authors: Jodot Paul
Published: March 2020

The three substages--the Sarmatian, the Meotic, and the Pontian proper--have not yet been differentiated in the upper Miocene continental deposits of the Rhone valley, France. On the basis of continental mollusks and mammals from the synclinal section of Cucuron (Vaucluse), three superposed faunas can be distinguished, which appear to be related to the three substages.
Etude des roches argileuses de quelques bassins houillers de la bordure occidentale du Massif Central
Authors: Kulbicki Georges , Vetter P.
Published: March 2020

Rather regular and constant argillaceous zones in Carboniferous formations of the coal basins at the western margin of the Central Massif, France, are of two principal types, those rich in micaceous clays (illite-montmorillonite) and those composed mainly of kaolinite. Both contain variable amounts of vermicular kaolinite (leverrierite) formed before consolidation by kaolinization of detrital mica particles in an acid milieu.
Le recif miocene du Languedoc
Authors: Chevalier Jean Pierre
Published: March 2020

The Miocene reef of the Languedoc region, France, originated at the edge of the Vindobonian shore following a change from marly to essentially limestone deposition. At present only scattered remnants remain. The fringing nature of the reef is shown by its passage westward into beach conglomerates or brackish and even lacustrine formations.
Deux lamellibranches interessants de la serie de Katrol dans le Kutch (Inde)

Published: March 2020

Describes two new species of pelecypods from the Katrol series (Jurassic) of the Cutch region, India.
Essai de coupe du Tell algerois
Authors: Mattauer Maurice
Published: March 2020

Detailed field and micropaleontologic investigations of outcrops along a north-south section across the Tell region, Algeria, from the eastern Ouarsenis massif through the Cheliff basin to the Miliana massif, show that the zone of complex structures is overthrust relative to the zone in which Cretaceous and overlying Miocene formations have been subjected to broad folding and in which Triassic diapirs are absent.
Aspects geotectoniques possibles de l'equilibre isostatique
Authors: Deicha Georges A.
Published: March 2020

Schemes illustrating the principal of isostasy usually neglect the problem of stability of equilibrium within individual crustal blocks. Block diagrams have the advantage of suggesting experimental verifications and calculations. Readjustments within blocks--such as those resulting from an oblique major fault--would cause relative changes of level within a floating block of uniform density. This complementary aspect of isostasy should be taken into account in geotectonic theories.
Sur un bilobite nouveau du Gothlandien de l'Ennedi (Tchad, A.E.F.), Cruziana ancora
Authors: Lessertisseur Jacques
Published: March 2020

Describes a new bifurcate bilobite form, Cruziana ancora, from the Gotlandian (Silurian) of the Ennedi massif, French Equatorial Africa, which is interpreted as an internal mold of the beginning of a tunnel excavated by a trilobite.
Nouvelles observations sur le "Cambro-Ordovicien" du Zemmour (Sahara occidental)
Authors: Sougy Jean
Published: March 2020

In the Zemmour region (northern Mauritania, French West Africa) of the western Sahara, beds assigned to the Cambro-Ordovician are apparently transgressive toward the north-northeast, for dolomitic limestones are found only in the south and west. Observations in the Oumat el Ham massif show that there are two distinct series in the sequence, the marine Oumat el Ham series, overlain discordantly by the continental Garat el Hammoueid series. A conglomerate containing pebbles of the uppermost beds of the Oumat el Ham usually marks the disconformity.
Les ecailles de Saint-Clement (Hautes-Alpes)
Authors: Debelmas Jacques
Published: March 2020

Strata younger than Oxfordian (Jurassic) have been identified in the autochthonous basement of the thrust slices of the Saint-Clement region, Hautes-Alpes, France, and an Ultradauphinois slice thrust over Subbrianconnais slices has been discovered in the basal complex of the Embrunais nappe. The resulting anomalous structure is found to be reflected in the Saint-Sauveur slices, which constitute the continuation of the Saint-Clement sequence, but are simpler in structure.
Donnees et hypotheses relatives aux nappes du Tell algerien
Authors: Caire Andre
Published: March 2020

The structure of the Tell ranges of Algeria can be explained by various tectonic schemes based on the observed facts. It is known that Glangeaud's zone I was subjected to slicing in the Nummulitic and uplift in the lower Miocene; these processes undoubtedly contributed toward formation of nappe C and at least part of nappe B. Sliding of the nappes probably took place along a surface produced by pre-Miocene planation.
Observations stratigraphiques et malacologiques sur les bassins lacustres de Saint-Alban-sur-Limagnole (Lozere) et de Massiac (Cantal)
Authors: Jodot Paul , Rey R.
Published: March 2020

The Tertiary history of the Saint-Alban-sur-Limagnole and Massiac basins (in Lozere and Cantal, France, respectively) is worked out from a study of the stratigraphic relationships and gastropod faunas of the fossiliferous lacustrine deposits. Descriptions of some of the gastropods (including one new species) are given.
Observations sur les flyschs des Alpes maritimes francaises et italiennes; sedimentologie, variations de facies
Authors: Kuenen Philip H.
Published: March 2020

In the Maritime Alps of France and Italy, there are Flysch complexes whose facies are similar but whose ages differ, as well as Flysch complexes of contrasting composition. The sedimentational features and facies of two of these complexes were studied with a view to interpreting depositional conditions. The constituents of the autochthonous Oligocene Annot sandstone complex came from the south. Measurements of current direction indicate that the sandstones of the overthrust helminthoid-bearing Flysch complex (upper middle Cretaceous) came from the southwest, locally from the westnorthwest. In neither case was the Argentera-Mercanton massif the source of the sands, although it may have supplied small amounts to the Annot sandstone.

Geologic information obtained from a well drilled for water midway between Clermont-en-Argonne and Les Islettes, France, and surface observations indicate that the region is a subsidence trough structurally related to the Marne double fault to the south.
Differenciation calcite-dolomite et anhydrite-gypse par colorations selectives sur echantillons macroscopiques
Authors: Megnien Claude
Published: March 2020

Describes a new modification of the copper nitrate method of distinguishing between calcite and dolomite macroscopically, in which greater color contrast is achieved by immersing the sample in an oxygenated solution. Anhydrite and gypsum can be distinguished by heating the sample above 102 degrees C, which transforms the gypsum into lustrous white CaSO 4 .1/2H 2 O.
Granites eutectiques ou metamorphiques? Discussion d'etudes recentes
Authors: Perrin Rene
Published: March 2020

Discusses recent works bearing on the question of the origin of granite. Bowen and Schairer conclude that crystallization of natural magmas ends with a eutectic liquid of granitic composition, and Tuttle and Chayes claim that the composition of natural granites is close to this eutectic. These conclusions are considered parts of a syllogism with no basis in reality. The origin of granites can only be explained in terms of metamorphic transformation.
Palaeomillepora liasica nov.gen. nov.sp., hydrozoaire nouveau du Lias de Vendee
Authors: Gabilly Jean , Lafuste J.
Published: March 2020

Describes a Liassic sponge, Palaeomillepora liasica n.g. n.sp., from the Vendee region, France, considered probably ancestral to the Milleporidae. It was found in association with numerous mollusks and corals in beds exhibiting a littoral detrital facies.
Discordance angulaire du Rhetien sur le Trias dans le massif de Peyre-Haute au S de Briancon; importance de l'erosion ante-rhetienne dans la zone brianconnaise
Authors: Debelmas Jacques , Lemoine M.
Published: March 2020

Fossiliferous Rhaetic beds overlie dolomitic Triassic deposits with angular unconformity in the Peyre-Haute massif, France. Less important pre-Dogger and pre-Malm erosional unconformities are also present in the Mesozoic sequence. The erosion at the end of the Triassic, corresponding in time to the reversal of subsidence resulting in the origin of the Brianconnais geanticline, appears to have been a major factor in the paleogeographic and tectonic history of the Brianconnais zone.
Revision des cirripedes acrothoraciques fossiles
Authors: Codez Jean , de Saint-Seine R.
Published: March 2020

A biometric and systematic study of acrothoracic cirripeds from Jurassic to Tertiary localities leads to a revision of the group. The new genera Simonizapfes (Liassic and Jurassic) and Brachyzapfes (Cretaceous) are erected. Together with Zapfella pattei, from which they are separated, they constitute the family Zapfellidae. The distinctions between this family and the Rogerellidae are tabulated. The stratigraphic range of each genus and probable environmental conditions are outlined.

Les depots sedimentaires quaternaires et actuels de l'archipel de Kerguelen
Authors: Aubert de la Rue Edgar
Published: March 2020

The surface deposits of the Kerguelen islands in the south Indian Ocean comprise Quaternary and modern sediments found at elevations between sea level and 500 meters. They consist mainly of moraines, littoral marine deposits resulting from reworking of the moraines, torrential and fluvial alluvium, eolian deposits, andformations of organic origin (diatomaceous mud and peat).
Des "charbons" d'origine marine
Authors: Bienner Francois , Feys R. , Louis M.
Published: March 2020

Material resembling lignite, found as intercalations in Liassic marine sequences at Severac and Vassy, France, is the product of transformation of the wood of conifers in a marine environment. From their mixed character, these products appear to be related to the bitumens; their chemical composition is closer to that of the keratogen of bituminous shales than to that of coal.
Les terrasses de la Garonne dans l'Agenais
Authors: Rieucau Louis
Published: March 2020

In the Agen region, France, the evolution of the Garonne valley has been retarded by the presence of limestone ledges. The river terraces therefore are narrow and discontinuous, making observation and dating difficult. Detailed petrographic analysis of the terrace sediments has made it possible to distinguish a high terrace, whose deposits consist mainly of quartz pebbles, and three lower terraces with quartzite and granite constituents.
