Authors: Radic Vega Juan , Delgado Torres Felipe 
Published: July 2022

The article propose to analyze to the social unrest in Latina American in the XXI century. We ask ourselves about the similarities and differences that they present to analyze the historical continuity that they represent. Our premise understands that although dissimilar, plural and temporarily disruptive, the current social conflict present connections that allow to draw a unity with respect to its meanings, establishing in its background an emancipatory practice, transformer and criticism of the current order. To do this, we analyze three specific cycles of social unrest, considering the cases of Argentine, Ecuador and Chile, at stopping at two specific areas; the event that triggers the mass protests and how is interpreted by the mobilized society through the analysis of the discourses and demands that we identify in each one of them. Second, observing the political reconfiguration that they potentially represent, considering some mechanisms of organization created during these cycles, and invite us to rethink the politics and democracy. The comparative perspective tries to construct a global reflection while the considered temporality invites us to think in a historical dimension the deep questioning of the fact hegemony that neoliberalism has established in the region, as well as the potential sensibilities, actors and values, which envision being facing a profound and inexorable change of time.
El artículo propone analizar las revueltas sociales en América Latina en el siglo XXI en perspectiva histórica. Nos interrogamos acerca de las similitudes y diferencias que presenta cada una de ellas para analizar la potencial continuidad que representan. Para ello, analizaremos tres ciclos específicos de revueltas sociales considerando los casos de Argentina (2001), Ecuador (2005), y Chile (2019), deteniéndonos en dos ámbitos determinados; el acontecimiento que desencadena las protestas masivas y cómo es interpretado por la sociedad movilizada a través del análisis de los discursos y reivindicaciones que identificamos en cada uno ellos. En segundo lugar, observando la reconfiguración política que potencialmente representan. Para ellos consideramos –brevemente— algunos mecanismos de organización surgidos durante estos ciclos y que invitan a repensar lo político y la democracia. La mirada comparada pretende construir una reflexión global mientras la temporalidad escogida invita a pensar en una dimensión histórica el cuestionamiento de fondo a la hegemonía de facto que ha establecido el neoliberalismo en la región así como los potenciales procesos de transición cultural que representan la emergencia de nuevas sensibilidades actores y valores, que vislumbran estar frente a un cambio de época profundo e inexorable.
La experiencia de la técnica: nihilismo y movilización total en Ernst Jünger
Authors: Soto Carrasco David 
Published: July 2022

The article analyses the conception of technique and the critique of Modernity in Ernst Jünger at the crucial moments of the First World War and the Weimar Republic, as paradigmatic manifestations of the historical consummation of nihilism and the decline of the bourgeois world. For Jünger, the experience of the Great War represents the triumph of the technique, which not only would have had a decisive warlike role, but also supposes a total mobilization of society and the formation of a new order. In this sense, the technique is imposed as the metaphysical foundation of an era that is revealed in the figure of the worker, which allows the overcoming of nihilism, through the subsumption of labour in violence. Finally, it is analysed Jünger’s reflections on the partiality and non- currently of Weimar and his proposal of total, nationalist and imperial mobilization.
El objetivo principal del artículo consiste es analizar la concepción de la técnica y la crítica a la modernidad en Ernst Jünger en los momentos cruciales de la Primera Guerra Mundial y la República de Weimar, como manifestaciones concretas de la consumación histórica del nihilismo y del declive del mundo burgués. Para Jünger, la experiencia de la Gran Guerra supuso el triunfo de la técnica, que no solo habría tenido un rol bélico decisivo, sino que prefiguraba una movilización total de la sociedad y la conformación de un orden nuevo. En este sentido, la técnica se impone como el fundamento metafísico de una época que se concreta en la figura del trabajador, que permite la superación del nihilismo, a través de la subsunción de trabajo a la violencia. Finalmente, se sintetizan las reflexiones de Jünger sobre la parcialidad y no actualidad de Weimar y se analiza su propuesta de movilización total, nacionalista e imperial.

Background
The gastrointestinal (GI) bacterial communities of sea lions described to date have occasionally revealed large intraspecific variability, which may originate from several factors including different methodological approaches. Indeed, GI bacterial community surveys commonly rely on the use of a single hypervariable region (HR) of 16S rRNA, which may result in misleading structural interpretations and limit comparisons among studies. Here, we considered a multi-locus analysis by targeting six HRs of 16S rRNA with the aims of (i) comprehensively assessing the GI bacterial consortium in rectal samples from Zalophus californianus pups and (ii) elucidating structural variations among the tested HRs. In addition, we evaluated which HRs may be most suitable for identifying intrinsic, structurally related microbiome characteristics, such as geographic variations or functional capabilities.

Methods
We employed a Short MUltiple Regions Framework (SMURF) approach using the Ion 16S™ Metagenomic Kit. This kit provides different proprietary primers designed to target six HRs of the 16S rRNA gene. To date, the only analytical pipeline available for this kit is the Ion Reporter™ Software of Thermo Fisher Scientific. Therefore, we propose an in-house pipeline to use with open-access tools, such as QIIME2 and PICRUSt 2, in downstream bioinformatic analyses.

Results
As hypothesized, distinctive bacterial community profiles were observed for each analyzed HR. A higher number of bacterial taxa were detected with the V3 and V6–V7 regions. Conversely, the V8 and V9 regions were less informative, as we detected a lower number of taxa. The synergistic information of these HRs suggests that the GI microbiota of Zalophus californianus pups is predominated by five bacterial phyla: Proteobacteria (~50%), Bacteroidetes (~20%), Firmicutes (~18%), Fusobacteria (~7%), and Epsilonbacteraeota (~4%). Notably, our results differ at times from previously reported abundance profiles, which may promote re-evaluations of the GI bacterial compositions in sea lions and other pinniped species that have been reported to date. Moreover, consistent geographic differences were observed only with the V3, V4, and V6–V7 regions. In addition, these HRs also presented higher numbers of predicted molecular pathways, although no significant functional changes were apparent. Together, our results suggests that multi-locus analysis should be encouraged in GI microbial surveys, as single-locus approaches may result in misleading structural results that hamper the identification of structurally related microbiome features.

A field experiment was conducted to evaluate the impact of crop productivity and soil nutrient availability under continuous cropping and fertilization. A single nutrient application or omission of nutrient or mineral fertilizer alone can deteriorate the soil nutrient availability and yield in long run. The result revealed that soil pH and EC have not changed substantially even after the repeated application of fertilizers over five decades. The use of balanced fertilizers either alone or integrated with organic manure (FYM) has significantly increased the grain and straw yield of maize. The yield increment of maize was observed 13.9 percent higher than 100% NPK and 18.3 percent higher than without the addition of S (S free). Balanced fertilization can improve the soil nutrients (N, P, K & S) and soil organic carbon instead addition of FYM @ 10 t ha-1 could increase the SOC and soil nutrients in long run in a sustainable manner. Concerning nitrogen, single nutrient (N alone) plots received low available nutrients and yield also it’s deteriorated the soil nutrients over long period. A build-up of available soil P and S was observed due to its continuous addition through fertilizer but soil K has reduced because of intensive cropping and high-yielding cultivars. Hence, for sustainable roduction, application of a recommended dose of mineral fertilization (100% NPK) along with FYM @ 10 t ha-1 may be used to achieve a higher yield, stable nutrient balance and soil quality over decades.
Evaluating the Degradation Effect of Bacterial Consortium from the Feces of Bos tarus and Fecal Matter on Crude Oil Polluted Soil
Authors: Owarieta Urhibo, Voke , Eunice A. Odesiri-Eruteyan, 
Published: July 2022

Aim: This study evaluated the effect of degradation of bacterial isolates from the feces of Bos tarus and fecal matter on crude oil polluted soil in a laboratory scale.
Study Design: This study covered the isolation of bacterial consortium from the fecal matter of Bos tarus obtained from Giriki Farms located at Gariki barn Uti, Delta State, Nigeria used to treat soil sample spiked with crude oil obtained from the Warri Refining and Petrochemical Company (WRPC)
Place and Duration of Study: The study was conducted in the Environmental Science laboratory, Federal University of Petroleum Resources, Effurun, Delta State, Nigeria. The research lasted for four months.
Methodology: Hydrocarbon utilizing bacteria consortium was isolated from the dung of Bos tarus using a carbon free medium employing pour plate/vapor phase techniques. The identified consortiums were screened to select the fastest degrader of hydrocarbons by 2,6-dichlorophenolindophenol (DCPIP). The best fit consortium was subjected to purification and identification of its bacterial make up using standard microbiological procedures. The selected consortium was standardized after washing to 0.1 optical density at 600nm and used to treat soil spiked with crude oil alone and with fecal matter. The degradation effect of the residual crude oil was determined by Gas chromatography.
Results: Results showed that isolates were capable and effective in degrading crude oil with performance enhanced in crude oil polluted soil with bacterial consortium andfecal matter (90.29%) and 78.00% in polluted soil with only bacterial isolates. This clearly points to the roles of elemental constituents of the fecal matter acting as a catalyst and bio-stimulant to hasten the rate of degradation of crude oil although not undermining the role of microorganisms.
Conclusion: The study revealed that microorganisms from the waste of Bos tarus are capable of degrading short and long chain hydrocarbons present in crude oil and the degradation process is enhanced if the ecological niche from which the isolates are drawn is maintained.

The menace of drug resistant pathogens is increasing and their level of evading conventional antimicrobials is rising. It is therefore important to discover new antimicrobials to counter the current challenges. Our preliminary investigation identified Bacillus subtilis subsp. subtilis 168 isolated from soil sample sourced from a river bank in Abuja, Nigeria, as the most potent antibiotic-producing bacteria among the other identified producers. The current study screened for the antimicrobial activity of the extract and fractions of the isolate by broth microdilution method. The minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and the ratio of the MBC/MIC were determined. All the tested pathogens were susceptible to the ethyl-acetate extract (MIC between 28.70 mg/ml and 57.40 mg/ml). The extract displayed bactericidal activity against all tested pathogens (MBC/MIC between 1.00 and 2.00) while Proteus mirabilis was least susceptible. The extract was purified by vacuum liquid chromatography and the fractions challenged with pathogenic strains. The fraction E was the most potent (MIC between 0.09 mg/ml and 0.75 mg/ml) and also bactericidal against all the test microbes (MBC/MIC between 2.00 and 2.11). GC-MS analysis of the purified sub fraction obtained from fraction E identified 13 compounds with different Retention time and peak areas. Among these were three major compounds which include: (i) bis(2-ethylhexyl) phthalate (ii) 1,4-epoxynaphthalene-1(2H)-methanol, 4,5,7-tris(1,1-dimethylethyl)-3,4-dihydro- (iii) D:B-Friedo-B':A'-neogammacer-5-en-3-ol, (3.beta.)-. Our findings suggest that Bacillus subtilis subsp. subtilis 168 isolated locally could serve as a valuable source of lead compounds for pharmaceutical and biotechnological purposes.
Neural Regulation of Cancer: Cancer‐Induced Remodeling of the Central Nervous System
Authors: Krishna Saritha , Hervey‐Jumper Shawn L. 
Published: July 2022

AbstractIn recent years, there have been significant advances in understanding the neuronal influence on the biology of solid tumors such as prostate, pancreatic, gastric, and brain cancers. An increasing amount of experimental evidence across multiple tumor types strongly suggests the existence of bidirectional crosstalk between cancer cells and the neural microenvironment. However, unlike cancers affecting many solid organs, brain tumors, namely gliomas, can synaptically integrate into neural circuits and thus can exert a greater potential to induce dynamic remodeling of functional circuits resulting in long‐lasting behavioral changes. The first part of the review describes dynamic changes in language, sensory, and motor networks following glioma development and presents evidence focused on how different patterns of glioma‐induced cortical reorganization may predict the degree and time course of functional recovery in brain tumor patients. The second part focuses on the network and cellular‐level mechanisms underlying glioma‐induced cerebral reorganization. Finally, oncological and clinical factors influencing glioma‐induced network remodeling in glioma patients are reviewed.

AbstractDifferent SrTiO3 thin films are investigated to unravel the nature of ultra‐low conductivities recently found in SrTiO3 films prepared by pulsed laser deposition. Impedance spectroscopy reveals electronically pseudo‐intrinsic conductivities for a broad range of different dopants (Fe, Al, Ni) and partly high dopant concentrations up to several percent. Using inductively‐coupled plasma optical emission spectroscopy and reciprocal space mapping, a severe Sr deficiency is found and positron annihilation lifetime spectroscopy revealed Sr vacancies as predominant point defects. From synchrotron‐based X‐ray standing wave and X‐ray absorption spectroscopy measurements, a change in site occupation is deduced for Fe‐doped SrTiO3 films, accompanied by a change in the dopant type. Based on these experiments, a model is deduced, which explains the almost ubiquitous pseudo‐intrinsic conductivity of these films. Sr deficiency is suggested as key driver by introducing Sr vacancies and causing site changes (FeSr and TiSr) to accommodate nonstoichiometry. Sr vacancies act as mid‐gap acceptor states, pinning the Fermi level, provided that additional donor states (most probably ) are present. Defect chemical modeling revealed that such a Fermi level pinning also causes a self‐limitation of the Ti site change and leads to a very robust pseudo‐intrinsic situation, irrespective of Sr/Ti ratios and doping.
Coordination Number Dependent Catalytic Activity of Single‐Atom Cobalt Catalysts for Fenton‐Like Reaction

Published: July 2022

AbstractSingle‐atom catalysts (SACs) are widely investigated in Fenton‐like reactions for environmental remediation, wherein their catalytic performance can be further improved by coordination structure modulation, but the relevant report is rare. Herein, a series of atomically dispersed cobalt catalysts with diverse coordination numbers (denoted as CoNx, x represents nitrogen coordination number) are synthesized and their peroxymonosulfate (PMS) conversion performance is explored. The catalytic specific activity of CoNx is found to be dependent on coordination number of single atomic Co sites, where the lowest‐coordinated CoN2 catalyst exhibits the highest specific activity in PMS activation, followed by under‐coordinated CoN3 and normal CoN4. Experimental and theoretical results reveal that reducing coordination number can increase the electron density of single Co atom in CoNx, which governs the Fenton‐like performance of CoNx catalysts. Specifically, the entire Co–pyridinic NC motif serves as active centers for PMS conversion, where the single Co atom, and pyridinic N‐bonded C atoms along with nitrogen vacancy neighboring the unsaturated Co–pyridinic N2 moiety account for PMS reduction and oxidation toward radical and singlet oxygen (1O2) generation, respectively. These findings provide a useful avenue to coordination number regulation of SACs for environmental applications.

AbstractEstablishing local built‐in electric field of 2D semiconductors is one of the promising strategies to regulate the oriented charge delivery to active centers for enhancing photocatalytic performance. Herein, a novel heptamolybdate polyanions‐intercalated porous g‐C3N4 ([Mo7O24]6−‐pCN) catalyst with integrating highly desirable visible‐light photocatalytic features is reported. After intercalation, the apparent reaction rate constants (kapp) of [Mo7O24]6−‐pCN for bisphenol A (BPA) and 4‐chlorophenol (4‐CP) photodegradation are remarkably enhanced, which are 9.0 and 6.4 times faster than those of pCN, respectively. Analogously, the kapp values of [Mo7O24]6–‐CN for BPA and 4‐CP removal are also improved by contrast with CN. The experimental results and density functional theory calculations indicate that a local built‐in electric field is formed in [Mo7O24]6−‐pCN with a polarization direction from aromatic rings of g‐C3N4 to the inserted [Mo7O24]6− clusters. Driven by the electric field, photogenerated carriers can be efficiently separated for better reactive oxidative species (ROSs) production. These O atoms are also proved as adsorption sites for phenols, greatly reducing the migration distance of ROSs and thus improving photocatalytic performances. This work offers a reliable strategy to construct local built‐in electric field via polyoxometalates intercalation for effective solar energy conversion and phenolic wastewater remediation.

Published: July 2022

AbstractSuppressing losses that originate from domain‐wall motion in ferroelectrics is essential to high‐power piezoelectric applications. Conventional models of the hardening effect assume that domain‐wall mobility can be greatly impeded due to the pinning of lattice defects or charge carriers. However, these models cannot satisfactorily explain the dramatical increase of mechanical quality factor from ≈500 to ≈2500 in ferroelectric sodium lithium niobate induced by annealing. In the present study, the specific hardening effect is systematically investigated from multiple perspectives, including kinetics, phase transition, and domain configuration. The enhancement is proposed to be associated with the thermally induced domain reconfiguration at the nanoscale approaching the ferroelectric‐paraelectric phase transition temperature. The comprehensive experimental observations reveal a unique mechanism of the hardening effect in ferroelectrics, shedding light on the enhancement of the performance of high‐power piezoelectric applications.

AbstractBipolar junction transistors (BJTs), the basic building blocks of integrated circuits, are deployed to control switching applications and logic operations. However, as the thickness of a conventional BJT device approaches a few atoms, its performance decreases substantially. The stacking of atomically thin 2D semiconductor materials is advantageous for manufacturing atomically thin BJT devices owing to the high carrier density of electrons and holes. Here, an atomically thin n–p–n BJT device composed of heavily doped molybdenum ditelluride (n‐MoTe2) and germanium selenide (p‐GeSe) sheets stacked over each other by van der Waals interactions is reported. In a common‐emitter configuration, MoTe2/GeSe/MoTe2 BJT devices exhibit a considerably high current gain (β  =  Ic /Ib = 29.3) at Vbe = 2.5 V. The MoTe2/GeSe/MoTe2 BJT device is employed to detect streptavidin biomolecules as analytes within <10 s. The real‐time response of the functionalized BJT device is examined at various concentrations of streptavidin biomolecules ranging from 250 to 5 pm. Such vdW BJT devices can trigger the development of state‐of‐the‐art electronic devices that can be used as biosensors to detect the various kinds of target DNA and proteins like spike protein of Covid‐19.
