EXPECTED OCCURRENCE OF THE BLIND ORE BODIES AT THE LOWER LEVELS OF THE BALEI DEPOSIT AND A MECHANISM OF THE RICH ORES FORMATION AT THE NEAR-SURFACE GOLD-SILVER ORE DEPOSITS
Authors: Nekrasov E. M.
Published: October 2018

The gold ore chimneys of 2 types have been shown to be developed at the near-surface deposits of gold and silver ores. These types are: 1 - bulk ones, of the vein-nested-veinlet ore bodies of stockwork shapes and 2 - small pay streaks of the ore bodies, appeared either in single veins or in the veins, being a part of the wide ore bundles. The example of the first type is the Central ore column of Balei deposit and the column of the Glavnaya (Main) vein of the Karamkenskoe deposit. A deiailed analyses of the graphic material, made by N.V. Petranovskaya for Balei deposit, confirms, that under the bottom of the ore controling vein №2 in the vertical interval from 100 to 250-350 m the rich ores can be prevailed in the zones, which are likely to join with ore bodies of Taseevsky site. The discovery of the new bulk gold ore chimnies is likely to be there. With this, an additional exploration of the south-east flanks of the Balei deposit is needed, that can lead to the discovery of the new bulk gold ore chimnies.
PHYSICAL-CHEMICAL FORMATION CONDITIONS OF URANIUM-TITANIUM-METAGEL MINERALIZATION AT THE GOLD-URANIUM ELKON DEPOSIT
Authors: Komarova M. M. , Komarov VL. B. , Aleshin A. P. , Krylova T. L.
Published: October 2018

A wide range of the temperatures of hydrothermal fluid regime (430-103 °C) has been revealed in the result of microthermometric study of the fluid inclusions in the minerals of pre-ore and post-ore stages developed at the Elkon deposit. Average temperatures, as well as the temperature variation are similar for both pre-ore and post-ore stages. It allows sure determination of temperatures of uranium ore formation as 400-120 °C. Fluids possessed Na-chloride, rarely Na-chloride-carbonate composition and moderate salinity (6-16 wt. % · NaCl equiv.). The wide range of tem-peratures confirms an assumption made before that various temperatures were the reason of formation of uranium mineralization both in the form of predominantly amorphous phase (U-Ti-metagel), as well as the rarely crystalline form (brannerite). Abrupt temperature decrease was apparently the main factor of the ore precipitation.

Numerical simulation of the electromagnetic fields variations under the formation of the fault rupture before earthquake
Authors: Shimelevitch M. I. , Obornev E. A. , Feldman I. S. , Novikov V. A.
Published: October 2018

A 2D geoelectric model of a heterogeneous geological medium has been developed taking into account the processes occurred in the geological subj ect of flexure type which transforms into an uplift-thrust structure as a result of deformations. The model is based on a hypothesis of the variation of electrical conductivity of geomaterials in the local area of the fault under subcritical stress-state conditions due to the geodynamical processes. In the shear stress maximum area, in the plane of fracture of the uplift-thrust type, a zone of increased fracturing is developed contributing to the essential decrease of electric resistance due to filling the fractures by fluid - so named «conductive split». A numerical simulation has demonstrated that when transiting from the quasi-stratllied model to a 2D model with the high-resistive shield a redistribution of the total current density in the medium is increased essentially due to the effect of the «conductive split», taking into account the assumed formation of the zone of fracturing. In this case, amplitude of the electromagnetic (EM) field for the longitudinal polarization increases far apart from the area of the «conductive split». The result obtained may be applied as a background for the development of the monitoring technique of the electromagnetic fields measured on a surface of the Earth far apart from the earthquake epicenter and directly over the fault for the controll ing of a level of the fault maturity for the occurrence of the seismic event.

Five adjacent eco-stratigraphic units have been considered (listed here, from the bottom to the top): eco-zones Cordaites clercii ... Abiella subovata (7 dominants of the plain sedtmentation level), Quadrocladus pachyphyllus ... Bipemphigus gennisi (29 dominants of the mountain, plain, lowland sedimentation levels), Quadrocladus pachyphyllus ... Echinolimnadia mattoxi (15 dominants of the plain sedimentation level), Elatocladus linearis ... Cornia vosini (13 dominants of the mountain, plain, lowland sedimentation levels), eco-series Ferganiella ... Cornia vosini (11 dominants of the plain and lowland sedimentation levels). The lower eco-zone belongs to Vishkilian (Severodvinian) stage (Upper Permian), the upper one - to the Triassic. The age of the deposits included in the other eco-zones, has been discussed. A complete set includes dominants of the arborescent layer, slope herbaceous cover, lowland herbaceous cover, standing basins, semi-flowing water basins, flowing water basins, coastal basins of mountain, plain, and lowland levels. In the names of the eco-zones the dominant of the arborescent layer of mountain (or plain) level is written to the left, flowing water (or coastal) basin of the lowland level is to the right (through the dot). Eco-zones clearly differ from each other in the composition of the dominants. The clearest boundary is the boundary of the two upper eco-zones. The boundary of the two lower eco-zones is less clear. The least clear boundaries are the boundaries of the eco-zones Quadrocladus pachyphyllus ... Bipemphigus gennisi, Quadrocladus pachyphyllus ... Echinolimnadia mattoxi, Elatocladus linearis . Cornia vosini. It may be prompted to include these three eco-zones in the Taimyrian region-stage, returning its originally suggested volume. It corresponds to the zones from the Clarkina bachmanni to the Stepanocites mostleri.
FORMATION CONDITIONS OF GROUNDWATER IN THE MEKONG DELTA (VIETNAM) BASED ON ISOTOPES RESEARCH OF OXYGEN AND HYDROGEN IN WATER
Authors: Hoang Quoc Viet Lam , Lisenkov A. B. , Lavrushin V. J.
Published: October 2018

The origin and formation of the groundwater in the Mekong Delta are the complex problem, which has not one solution nowadays. So the exploitation scheme still has many limitations. In the aquifers of the Mekong Delta there are both fresh water and mineralized water, which are very complex and heterogeneous in the distribution. The mineralized water has been considered to have sedimentagenous genesis (buried seawater), and freshwater has been believed to originate from infiltration of meteoric water. Studying of the stable isotopes of oxygen and hydrogen of the groundwater in the Mekong Delta has shown that the groundwater originates mainly from the infiltration of the meteoric water. In addition, a significant factor in the formation of groundwater in the Middle, Lower Pliocene and Miocene aquifer is the mixing of the meteoric and sea waters. Increasing in values of stable isotopes with growing depth of groundwater is related with that the recharging areas of Paleogene (deep) aquifers are distributed higher by absolute depths and farther from the coastline than recharging areas of Quaternary (shallow) aquifers. The results of the research can be used to optimize the scheme for the exploitation of the fresh groundwater, limiting the intrusion of sea water in the exploited groundwater in the Mekong Delta.

Authors: Petrochenkov D. A.
Published: October 2018

Concretions with fossils of the Ulyanovsk region are a new kind of jewelry and ornamental raw materials. Concretions are located in the middle part of the section of the Hauterivian sediments, which formed by dark gray dense clays. Concretions are dense, of dark gray or black colour, abundant with fragments of bivalves shells, less often with ammonites, and consist from, wt. %: calcite 85, aragonite 8, quartz 2, apatite 2, pyrite 2 and aluminosilicates 1. From the trace-elements there is Sr with a content of 0,08 wt. %. The contents of radioactive and carcinogenic elements are at background level. Aragonite constitutes the walls of the shells. Calcite is a cement of marl, and also constitutes fragments of shells. Pyrite constitute significant zones mainly in the outer parts of the concretions. In the central parts, it is presented as a rare dissemination. Quartz and aluminosilicates are minerals of bottom sediments. Calcite, apatite and pyrite are secondary minerals formed during the process of diagenesis of marine sediments. Contents of the trace-elements in calcite, wt. %, are: Mg from 0,52 to 2,19 and Mn from 0,34 to 2,13. There is no Fe, which is concentrated in pyrite. The structural features and chemical composition of minerals have been established. Concretions with fossils of the Ulyanovsk region are a technological high-decorative jewelry and ornamental material which allows producing of a wide range of jewelry and souvenirs.
THE N.A. GOLOVKINSKY’S FUNDAMENTAL FACIAL LAW — PROBLEMATICS AND NEW HORIZONS
Authors: ALEKSEEV V. P. , AMON E. O.
Published: October 2018

Famous Russian geologist N.A. Golovkinsky published 150 years ago an important scientific work, where the phenomenon of lateral  displacement (movement) of homogeneous lithological layers  («slide» over time) was asserted. This created the most significant  prerequisites for the fundamental facial law: the layers, lying nearby,  were formed in the same sequence vertically. The law was  formulated a little later by A.A. Inostrantsev, and later  «rediscovered» by J. Wal- ter. The ideas, developed by N.A.  Golovkinsky, subsequently found the application in the study of  geological cyclicity, and currently in the booming seismic  stratigraphy. The creative improvement and continuation of  theoretical positions  contained in the Golovkinsky’s work allowed to  advance a method of facially-cyclic analysis, which has been  success- fully used in the study of many coal-bearing strata, and is  currently used for coal-free deposits of the West Siberian oil and gas  basin. Methodically, they develop an understanding of causality and  correspond to the principles of synergetic world-view. The main  content of these ideas remains relevant in the light of new realities  of cognitive process (nonlin-ear science, endovision).
MORPHOLOGY OF DIAMONDS DISSOLVED IN THE Fe-S MELT AT DIFFERENT SULFUR CONTENTS
Authors: SONIN V. M. , GRYAZNOV I. A. , ZHIMULEV E. I. , CHEPUROV A. I.
Published: October 2018

An experimental study of the process of the dissolution of diamonds in a sulfur-containing iron melt with different contents of sulfur (10,  15, 20, 25, 30 wt. %) at 3,5 GPa and 1400°C has been carried out.  The obtained results indicate that under the realized conditions, the  plane-faced diamond crystals of octahedral habit are transformed  into a curved octahedroid shape with morphological characteristics similar to  natural diamonds from kimberlites. It has been concluded that metal- sulphide melts, given their relatively low melting points, could affect the  safety of diamonds in the mantle. The presence of sulfur reduces  the solubility of carbon and tends to zero in the Fe-S melt compositions  close to eutectic (25 and 30 wt. %). That is, the presence of sulfur has a favorable effect on the stability of diamonds.
ON THE NATURE OF OXIDE FERROMANGANESE ORES OCEAN
Authors: AVDONIN V. V. , ZHEGALLO E. A. , SERGEEVA N. E.
Published: October 2018

Oxide ores of the global ocean — cobalt-rich crusts and ferromanganese nodules are of bacterial origin and identified as  stromatolites and onkolites. Pillar structure of ferromanganese  stromatolites and festoon-shaped structures of onkolites represent  the bacterial mats, formed by interbedding of fossilized bacterial  biofilms. The appearance of ore-forming types of procaryotic family  and their evolution are defined by major biosphere events. On the  case study of the ferromanganese  nodules of Magellanic mountains and cobalt-rich crusts of the province  of the Clarion-Clipperton, the main stages of the evolution of structural  forms of bacterial communities have been revealed. It has been shown that the change of phases happened due to the influence of  major tectonic, volcanic and other geological events.
ABOUT ANCIENT SOURCES OF DIAMONDS PLACERS
Authors: ZINCHUK N. N.
Published: October 2018

Basing on generalization of large actual material on complex investigation of diamond, its characteristic in Upper Paleozoic and  Mesozoic sedimentary thick layers of the Siberian platform has been  provided. It has allowed receiving new data on composition features  and distribution of diamond in recent sediments of main  diamondiferous regions of Lena-Anabar, Central-Siberian and  Tungusskaya sub-provinces. On the north-east of Siberian platform,  the region of Kyutyungdinsky graben and nearby territories,  perspective for the discovery of rich kimberlite bodies with specific  dia- monds, are of the most interest. Special attention has been paid to the Central-Siberian sub-province, where it has been convincingly  shown that the area of development of individual diamond macro- associations is limited by a specific diamondiferous region, within  which complexes of different in age terrigenous and coastal Upper  Paleozoic and Mesozoic sediments are developed. The complex of  features of diamonds from placers of the described platform testifies  by morphology, coloration, hard inclusions, internal structure,  photoluminescence and admixture composition about plurality of  primary sources and availability of still undiscovered kimberlite  bodies within many diamondiferous regions. Application of  typomorphic features of crystals for restoration of exogenous history of diamonds on the path from primary sources to the sites of modern allocation in placers, as well as for paleogeographical reconstructions of distribution of ancient productive thick layers and clarification of  diamondiferous material drift direction, has a significant importance.  Proximity of typomorphic features of diamonds in sedimentary thick  layers of these ages, identified in some diamondiferous regions,  testifies about formation of these collectors due to washout of more  ancient productive layers or Middle Paleozoic primary sources.  Polygeny of mineralogical associations of diamonds from different in age placers within some diamondiferous regions has been noted,  which may be successfully used when forecasting and prospecting primary sources of the mineral.

El valor de la razón y su relación con la fe. John Henry Newman y C. S. Lewis: una mirada.
Authors: Vázquez Romero Irene
Published: October 2018

Sobre la base de la comparación de textos de Newman y Lewis, la autora muestra la coincidencia de planteamiento entre ambos en la consideración de la relación entre la fe y la razón. El ensayo señala el paralelismo en las tres vías naturales de conocimiento religioso del hombre: la inteligencia humana, la experiencia de la vida y el testimonio de la tradición. Sobre esas tres vías se analiza cómo tanto Newman como Lewis se esforzaron por comprender su propia inteligencia de la fe en relación con su inteligencia de la realidad de modo que tuviera incidencia real en la vida.

Comunidad y escritura alrededor de la Bildung. El valor de la mujer en el pensamiento de Friedrich Schlegel y Friedrich Schleiermacher.
Authors: Dobre Catalina Elena
Published: October 2018

El presente trabajo muestra, en el contexto del romanticismo alemán, el aporte de la mujer para el desarrollo de la cultura, por un lado y, por otro, cómo la implicación de las mujeres en la escritura mediante su educación y la inteligencia, inspiraron a dos filósofos de la época: Friedrich Schlegel y Friedrich Schleiermacher. Para ambos la presencia femenina representó una fuente de inspiración para sus obras y, en el caso de Schleiermacher para el desarrollo de sus ideas éticas. Los dos reconocieron el valor de la mujer como fundamental para el hombre, ya que mediante la mujer, el hombre puede encontrar su redención. La mujer es también, para ambos, un ser capaz de valer por sí misma, pero también capaz de crear comunidades de amor (amistad/ matrimonio).
Foucault y el concepto biológico de raza: entre el poder y la ciencia.
Authors: Mejía Fernández Ricardo
Published: October 2018

En este artículo examinamos el concepto biológico de raza en el plano filosófico y en el plano científico. Primero nos ocuparemos de la crítica de Michel Foucault al racismo desde la bio-política y, en un segundo gran apartado, recorreremos la historia de la ciencia para mostrar si el racismo biológico cuenta con algún tipo de fundamentación científica. El resultado general más importante es que el concepto biológico de raza deriva de la lucha de poder entre las sociedades y sus individuos, que optaron por subordinar la ciencia para preservar su hegemonía político-racial.

Each procedure is associated with significant recurrence rate.Objective : The aim of this study is to report the effectiveness, complications following laparoscopic ventral mesh rectopexy in patients with full thickness rectal prolapse.Methods : The study is a retrospective evaluation of 6 consecutive patients by a single attending surgeon in a general and laparoscopic surgery unit,between July 2014 to June 2016. Peritoneum was incised at the pouch of Douglas or rectovesical pouch, space created between the rectum and the vagina or urinary bladder, polypropylene mesh was fixed to the rectum with non-absorbable suture and to the promontory of the sacrum with same suture instead of staples. In females, the mesh was also fixed anteriorly with posterior fornix of vagina. The peritoneum was suture closed over the mesh. Patients were reviewed at 1 and 6 months, then annually to assess recurrence, morbidity and mortality.Result : There was no recurrence or mortality among four female and two male patients. Morbidity consistedof chronic deep perineal pain in one youngmale patient who was treated conservatively with oral analgesic.Conclusion : LVMR seems to emerge as a safe and effective procedure to treat full thickness rectal prolapse, but large series and long term results are needed and we are continuing the study for the same.Bangladesh Crit Care J September 2018; 6(2): 71-73
Therapeutic hypothermia in Post - cardiac arrest : It is time to revisit the guidelines.
Authors: Shirin Afroz , Islam Tasbirul
Published: October 2018

Background: Targeted Temperature Management (TTM), previously known as therapeutic hypothermia is an important tool for prevention and reversal of neurological injury and mortality reduction. Over the recent period, the use of induced hypothermia has raised many questions and recent large, randomized controlled trials (RCTs) have failed to demonstrate the benefit of TTM on clinical outcomes. The objective of this article was to compare different studies on neurological outcomes after use of TTM in different clinical situations, different temperatures and rates of cooling.Methods: We incorporated studies from 1950s to recent years using search engines like PubMed, Science Direct, Google Scholar.Results: Initial two small, unblinded trials have demonstrated improved neurological outcome in out of hospital shockable cardiac arrest. Recent studies showed that TTM was not associated with higher rates of survival or favorable neurological outcome in patients with IHCA and was rather associated with potential harm, lower likelihood of survival after discharge and long term neurological survival. TTM also didn’t show any favorable results in non-shockable cardiac arrests. Hypothermia of 36°C did not confer much benefit over 32°C -34°C.Conclusion: Recent large studies didn’t show no strong evidence that TTM is highly effective. Further methodologically robust studies are required in both shockable and non-shockable cardiac arrest for TTM to have any effect on neurological outcome.Bangladesh Crit Care J September 2018; 6(2): 84-87
Contextualizing Mes Aynak
Authors: Klimburg-Salter Deborah
Published: October 2018

Future generations of scholars may see Mes Aynak as an unique archaeological complex which comprises an extraordinary number of diverse functions and thus provides crucial primary evidence for the history of Inner and South Asia during the 1st millennium AD and most likely earlier—that is, with luck. Historians and archaeologists are uncertain what the future will bring—will the site be destroyed by war, copper mining or a lack of controlled excavation? All of these circumstances have threatened the integrity of the site since exploration first began in the 1960s. This short article presents a brief summary of the literature on Mes Aynak and the present archaeological situation.

The coconut is a major crop of many tropical countries, with the endosperm being one of its main products. The coconut soft-endosperm variants, the Makapuno and the Lono, are emerging as economically important. This review describes this crop, its salient endosperm phenotypes and the prevailing hypotheses associated with these. We also collate the literature on the Makapuno and provide a comprehensive review of the scarce information on the Lono. We review the current tenets of plant DNA methylation and provide examples of altered phenotypes associated with such methylation changes. We explore how the changes in the methylome affect endosperm development and the tissue culture process. We further cite the epigenetic basis of an altered endosperm phenotype of a closely related species to the coconut, the oil palm. We discuss how such modifications could affect coconut endosperm development, yielding the Makapuno and Lono phenotypes.

Methionine 77 in calmodulin can be stereospecifically oxidized to methionine sulfoxide by mammalian methionine sulfoxide reductase A. Whether this has in vivo significance is unknown. We therefore created a mutant mouse in which wild type calmodulin-1 was replaced by a calmodulin containing a mimic of methionine sulfoxide at residue 77. Total calmodulin levels were unchanged in the homozygous M77Q mutant, which is viable and fertile. No differences were observed on learning tests, including the Morris water maze and associative learning. Cardiac stress test results were also the same for mutant and wild type mice. However, young male and female mice were 20% smaller than wild type mice, although food intake was normal for their weight. Young M77Q mice were notably more active and exploratory than wild type mice. This behavior difference was objectively documented on the treadmill and open field tests. The mutant mice ran 20% longer on the treadmill than controls and in the open field test, the mutant mice explored more than controls and exhibited reduced anxiety. These phenotypic differences bore a similarity to those observed in mice lacking calcium/calmodulin kinase IIα (CaMKIIα). We then showed that MetO77 calmodulin was less effective in activating CaMKIIα than wild type calmodulin. Thus, characterization of the phenotype of a mouse expressing a constitutively active mimic of calmodulin led to the identification of the first calmodulin target that can be differentially regulated by the oxidation state of Met77. We conclude that reversible oxidation of methionine 77 in calmodulin by MSRA has the potential to regulate cellular function.

In plants, the mitochondrial thioredoxin (TRX) system generally comprises only one or two isoforms belonging to the TRX h or o classes, being less well developed compared to the numerous isoforms found in chloroplasts. Unlike most other plant species, Arabidopsis thaliana possesses two TRXo isoforms whose physiological functions remain unclear. Here, we performed a structure–function analysis to unravel the respective properties of the duplicated TRXo1 and TRXo2 isoforms. Surprisingly, when expressed in Escherichia coli, both recombinant proteins existed in an apo-monomeric form and in a homodimeric iron–sulfur (Fe-S) cluster-bridged form. In TRXo2, the [4Fe-4S] cluster is likely ligated in by the usual catalytic cysteines present in the conserved Trp-Cys-Gly-Pro-Cys signature. Solving the three-dimensional structure of both TRXo apo-forms pointed to marked differences in the surface charge distribution, notably in some area usually participating to protein–protein interactions with partners. However, we could not detect a difference in their capacity to reduce nitrogen-fixation-subunit-U (NFU)-like proteins, NFU4 or NFU5, two proteins participating in the maturation of certain mitochondrial Fe-S proteins and previously isolated as putative TRXo1 partners. Altogether, these results suggest that a novel regulation mechanism may prevail for mitochondrial TRXs o, possibly existing as a redox-inactive Fe-S cluster-bound form that could be rapidly converted in a redox-active form upon cluster degradation in specific physiological conditions.
Ghost Spectroscopy with Classical Correlated Amplified Spontaneous Emission Photons Emitted by An Erbium-Doped Fiber Amplifier

Published: October 2018

We demonstrate wavelength-wavelength correlations of classical broad-band amplified spontaneous emission (ASE) photons emitted by an erbium-doped fiber amplifier (EDFA) in a wavelength regime around 1530 nm. We then apply these classical correlated photons in the framework of a real-world ghost spectroscopy experiment at a wavelength of 1533 nm to acetylene ( C 2 H 2 ) reproducing the characteristic absorption features of the C-H stretch and rotational bands. This proof-of-principle experiment confirms the generalization of an ASE source concept offering an attractive light source for classical ghost spectroscopy. It is expected that this will enable further disseminating ghost modality schemes by exploiting classical correlated photons towards applications in chemistry, physics and engineering.
Microscopic Elastic and Plastic Inhomogeneous Deformations and Height Changes on the Surface of a Polycrystalline Pure-Titanium Plate Specimen under Cyclic Tension
Authors: Tada Naoya , Uemori Takeshi
Published: October 2018

A cyclic tensile test was carried out using a plate specimen of commercial pure titanium on a digital holographic microscope stage. Microscopic deformation of the grains was observed, and their height distribution was measured on the specimen surface. Each grain showed nanoscopic movement up and down, as well as reverse movement corresponding to specimen loading and unloading. We suggest that the different grain-specific changes in height were caused by microscopic inhomogeneities in the material, such as differences in the crystal orientation and geometries of both the surface and subsurface grains. Changes in grain height increased with tensile load, and a strong relationship was found between the height changes that occurred under elastic and plastic conditions. This suggests that microscopic plastic deformation is predictable from microscopic elastic deformation. In order to investigate the plastic deformation of grains in more detail, slip-line angles were measured after the tensile test. We found slip lines with similar angles in neighboring grains, suggesting that the plastic deformation of grains was not independent, but rather was related to that of surrounding grains and influenced by the deformation of subsurface grains.
Impact and Control of Reflected Noise from an Overpass Bottom

Published: October 2018

This study examines the effects of noise reflected from the overpass bottom under various conditions using onsite measurements and model simulation. Reflected noise from the overpass bottom may be as high as 8 dB(A). Bottom materials (steel and reinforced concrete (RC)) have no discernible effect on the reflected noise level. As the height of an overpass increases, the level of reflected noise decreases. When an overpass is parallel to the noise source (i.e., the freeway), the size of the area impacted by reflected noise increases. As the sound absorption rating of the material installed at the overpass bottom increased, the level of reflected noise decreased. A sound absorbing material with a sound absorption rate of at least 0.60 is recommended to reduce reflected noise level. When the distance between the overpass side and a receiver exceeded 30 m, the level of reflected noise level reduced significantly. Therefore, if the distance between a residential area and overpass could be increased to create a buffer zone coupled with the installation of sound absorbing material at the overpass bottom, the impact of reflected noise on nearby residents can be reduced.
New Reentrant Insulating Phases in Strongly Interacting 2D Systems with Low Disorder

Published: October 2018

The metal-insulator transition (MIT) in two-dimension (2D) was discovered by Kravchenko et al. more than two decades ago in strongly interacting 2D electrons residing in a Si-metal-oxide-semiconductor field-effect transistor (Si-MOSFET). Its origin remains unresolved. Recently, low magnetic field reentrant insulating phases (RIPs), which dwell between the zero-field (B = 0) metallic state and the integer quantum Hall (QH) states where the Landau-level filling factor υ > 1, have been observed in strongly correlated 2D GaAs hole systems with a large interaction parameter, rs, (~20–40) and a high purity. A new complex phase diagram was proposed, which includes zero-field MIT, low magnetic field RIPs, integer QH states, fractional QH states, high field RIPs and insulating phases (HFIPs) with υ < 1 in which the insulating phases are explained by the formation of a Wigner crystal. Furthermore, evidence of new intermediate phases was reported. This review article serves the purpose of summarizing those recent experimental findings and theoretical endeavors to foster future research efforts.
