AbstractThe results of studies of the optical properties of ensembles of colloidal CdS quantum dots passivated by thioglycolic acid are reported. The average dimensions of the quantum dots lie in the range from 1.7 to 5.8 nm. By X-ray diffraction studies and Raman spectroscopy, it is established that quantum dots crystallize with the formation of a cubic crystal lattice. The systematic features of the quantum-confinement effect in the optical absorption and luminescence spectra, as well as in the luminescence excitation spectra, are established. The features manifest themselves as a blue shift of the corresponding bands with decreasing quantum-dot dimensions. From analysis of the nanosecond luminescence kinetics, it is concluded that experimentally observed radiative recombination proceeds by the donor–acceptor mechanism.
Latinoamérica: Estado y política de desarrollo. Hacia una tipología del Estado y la política de desarrollo
Authors: Martínez Escamilla Ramón 
Published: August 2018

En este artículo se analizan dos características del Estado: como órgano político supremo de la sociedad y como agente económico. Se señala que América Latina se organiza y diferencia por países que exhiben entre sí diverso grado de desarrollo -político y económico-, lo que implica que sus estructuras internas de poder se encuentran a diferente y diversa distancia del Estado moderno. No obstante, el diverso grado de desarrollo político, los países latinoamericanos en general iniciaron durante la década de los ochenta un formal y complicado movimiento hacia la democracia.
Alternativas para la reactivación de la economía mexicana
Authors: Guillén Romo Arturo 
Published: August 2018

El autor caracteriza la crisis de la economía mexicana de 1994 como crisis de gestación del modelo neoliberal. Para salir de la crisis, plantea la necesidad de construir una estrategia alternativa de desarrollo que es una tarea muy compleja, ya que su éxito dependerá no solamente de su solidez teórica sino de la puesta en marcha de una reforma política profunda que siente las bases de un sistema democrático. Una estrategia alternativa de desarrollo deberá dar mayor importancia al desarrollo del mercado interno y a la articulación de cadenas productivas, sin descuidar el fomento de las exportaciones y la inserción dinámica de México en la economía internacional. Ello implica el diseño de una política industrial y agropecuaria que induzca un desarrollo desde dentro que permita crear un sistema productivo nacional coherente e integrado
Cambio estructural: dualidad macroeconómica. Caracterización del desequilibrio externo en la economía mexicana
Authors: Ortíz Cruz Etelberto 
Published: August 2018

El modelo de desarrollo dominante, se presume, descansa en dos características esenciales: cero subsidios o transferencias a los agentes productivos y cero déficit público. Estos postulados son consecuentes con la naturaleza de un modelo basado en el proceso de mercado como único criterio de racionalidad. Este artículo propone que, en oposición a lo que se ha postulado, el modelo real en el que opera la economía mexicana descansa en realidad en cuantiosas transferencias y subsidios implícitos debido a que los operadores de mercado generan un importante déficit en el ámbito de las decisiones privadas. En embargo, este "déficit privado" no se resuelve en la esfera privada, sino que pasa a la sociedad como endeudamiento público, sea interno o externo. El déficit privado aparece en la forma de déficit comercial externo. Éste bien puede ser el resultado de una política monetaria errónea. Lo cierto es que de manera sistemática se observa una presión a la sobrevaluación de la tasa de cambio. En este trabajo se presenta un modelo que muestra las consecuencias macroeconómicas generadas por la forma en que se ha financiado la operación del déficit privado en particular que conduce a romper con las bases en que se asienta el modelo mismo, es decir, contra sus premisas de equilibrio fiscal.
La globalización como causante de la crisis económica actual
Authors: Huerta G. Arturo 
Published: August 2018

El presente trabajo analiza cómo la globalización ha llevado al predominio del movimiento del capital financiero sobre el movimiento de las mercancías. La internacionalización de los mercados de capital ha exigido la homologación de las políticas económicas en escala mundial, a fin de evitar la inestabilidad creciente de tales mercados, como de las monedas, la consecuente desvalorización del capital financiero. Las políticas privilegian la rentabilidad del capital financiero y actúan en detrimento del capital productivo, de la dinámica de acumulación de las empresas y del ingreso de los individuos, lo que termina por presionar sobre los fundamentos económicos y comprometen la capacidad de pago del servicio de la deuda interna y externa. Ello se ha traducido en problemas de inestabilidad bancaria y en intervenciones crecientes del FMI que transfiere recursos a las economías con problemas a fin de que puedan cubrir sus obligaciones financieras y evitar la generalización de crisis de pagos que comprometan al sistema financiero internacional

Published: August 2018

The aim of this study was to reveal the effects of four endophytic bacteria (EB) (Ochrobactrumsp. CB36/1, Pantoea agglomerans CC37/2, Bacillus thuringiensis CA41/1 and Pseudomonas fluorescens CC44) on the plant development of tomato and pepper and the effects against bacterial spot disease caused by Xanthomonas euvesicatoria (Xe) in both hosts. EB applied on tomato and pepper seedlings cultivated in a sterile peat growing medium in a climate chamber in two different periods to the roots. The pathogen inoculated on the leaves by spraying. Disease severity was measured by different scales for tomatoes and peppers, and plant development parameters were determined at the end of the study. The antagonistic effects of EB against Xe and 1-Aminocyclopropane-1-carboxylic acid (ACC) deaminase activities were determined with in vitro studies. The effect of endophytic bacteria on tomato and pepper varied according to the host plant x endophyte x pathogen combination. While no bacteria were effective against the pathogen in vitro, Ochrobactrum sp. CB36/1 inhibited the disease severity by 37% in tomato plants, but this effect was not observed in pepper. Tomato and especially pepper plants under disease stress had root and shoot fresh and dry weight increased by 28% to 128% by EB. The measurable effects of EB under biotic stress were determined to be higher than in stress-free conditions. In conclusion, the endophytic bacteria used in the study have potential for use within sustainable integrated agricultural concept framework, with their effects determined to vary according to the host, pathogen and endophytic bacteria.
DESNUDANDO A EVA: LA VIOLENCIA FEMENINA
Authors: Huerta Héctor Cerezo 
Published: August 2018

El presente texto desarrolla un análisis reflexivo sobre la violencia intencional ejercida por mujeres en sus relaciones de pareja; un fenómeno social considerado aislado, carente de datos epidemiológicos consistentes y hasta cierto punto “políticamente incorrecto” e indigno de atención clínica por el matiz “reactivo o defensivo” por el cual tienden a enmarcarse las agresiones femeninas. Sin embargo, la violencia conyugal se construye entre dos y, desde una visión sistémica en esa interacción, la mujer también tiene una participación activa al recurrir a conductas verbales durante los episodios violentos, mismas que fungen como conductas detonantes y retroalimentadoras de la agresión física, por la que optan los varones. Así también, las mujeres son proclives a la utilización de estrategias violentas diferentes a las ejercidas por el hombre y éstas se caracterizan por el uso de agresiones psicológicas, comunicativas, alienación de los hijos hacia el padre de familia, chantaje emocional y manipulación de la vida sexual. Abstract: The present text develops a reflective analysis about the intentional violence carried out by women in their relationships; a social phenomenon considered isolated, lacking consistent epidemiological data and until a certain point “politically incorrect” and worthless of clinical attention by the nuance “reactive or defensive” whereby tend to be framed female aggression. However, marital violence is built between two and from a systemic vision in this interaction; women also have an active participation by resorting verbal behaviors during violent episodes, same that act as detonating behavior and feedback from the physical aggression, by which choose men. Also, women are prone to the use of different violent strategies as exercised by man and they are characterized by the use of psychological aggression, communicative, aligning of children to the parent, emotional blackmail and manipulation of sex life.

Authors: Raouf Marian R , Sayed Mohamed , Rizk Hazim A , Hassuna Noha Anwar 
Published: August 2018

Introduction: Surgical wound infection is a serious problem, especially with metallo-beta lactamases (MBLs)- producing gram-negative bacteria as Pseudomonas aeruginosa. The main objective of this work was to evaluate for the first time in Minia- Upper Egypt, the incidence of imipenem-resistant Pseudomonas aeruginosa infection of surgical wounds particularly that mediated by MBL production.
Methodology: P. aeruginosa was isolated from infected wounds by swabs and underwent full microbiological identification and Antibiotic Susceptibility testing. MBL production was tested by E-test and PCR was used for imipenemase (blaIMP) and Verona integron-encoded metallo-beta-lactamase (blaVIM) gene detection.
Results: Out of 200 pus samples collected from surgical site infections, P. aeruginosa had the prevalence rate of 35%. Imipenem resistance was found in 28.57% of the isolated Pseudomonas aeruginosa. The prevalence of MBL-producing isolates among Imipenem-resistant P. aeruginosa (IRPA) was 85 % by phenotypic method with 29% of them harboring blaVIM gene. High resistance rates to other classes of antibiotics were reported among the isolates with multi-drug resistance (MDR) detected in 97.3% of the isolates.
Conclusion: To our knowledge, this is the first report in Minia, Upper Egypt describing the relatively high incidence of IRPA in infected surgical wounds with MBLs involved in the majority of isolates.

Published: August 2018

AbstractAlkyl aryl ketones are important structures with applications in many areas of chemistry. Hence, efficient procedures for their production are particularly attractive. In this communication, a general and efficient carbonylative cross‐coupling of aryl iodides and unactivated alkyl bromides is presented. By using a simple palladium catalyst, a series of alkyl aryl ketones were synthesized in moderate to excellent yields from readily available alkyl and aryl halides in an In‐Ex tube with formic acid as the CO source. In this study both primary and secondary alkyl bromides/iodides were suitable coupling partners. Additionally, this method can also be employed for the late‐stage functionalization of complex natural products and polyfunctionalized molecules.magnified image

Published: August 2018

AbstractAu and Ru nanoparticles (NPs) have been deposited on Siralox® substrate by impregnation and chemical reduction, respectively (Au‐Ru‐S). The as‐prepared material is very active in the selective CO2 methanation to CH4 at temperatures below 250 °C. In addition, Au‐Ru‐S shows enhanced CH4 production upon irradiation with UV/Vis light starting at temperatures higher than 200 °C, although the contribution of the photoassisted pathway of CH4 production decreases as the temperature increases. Thus, a maximum CH4 production of 204 mmol gRu−1 at 250 °C upon 100 mW cm−2 irradiation was achieved. Control experiments, in which Ru‐S and Au‐S materials were used, revealed that Ru NPs are the CO2 methanation active sites, while Au NPs contribute by harvesting light, mainly visible as a consequence of the strong Au plasmon band centered at 529 nm. The visible light absorbed by the plasmonic band of Au NPs could make them act ass local heaters of the neighboring Ru NPs, increasing their temperature and enhancing CH4 production.
Electrocatalytic Upgrading of Biomass‐Derived Intermediate Compounds to Value‐Added Products
Authors: Li Kui , Sun Yujie 
Published: August 2018

AbstractThe continuous advance in exploring renewable energy resources such as solar and wind will certainly alleviate our reliance on limited fossil reserves. However, the sustainable development of mankind demands not only energy but also carbon‐based chemical goods. Unfortunately, exploitation of renewable energy resources like solar and wind will not lead to any carbon‐based chemicals. The only sustainable and green carbon source is biomass, the scale of annual production of which has an immense potential to complement that of fossil‐derived carbons. To utilize biomass in economically effective ways, many catalytic processes have been investigated. Among various strategies of biomass refinery, electrocatalytic upgrading stands out as an attractive option because of its benign operation conditions, high energy efficiency, and convenient control on production rate and selectivity using electrochemical parameters. This Minireview showcases several electrocatalytic systems for both reductive and oxidative upgrading of representative biomass‐derived intermediate compounds, including 5‐hydroxymethylfurfural, furfural, levulinic acid, glycerol, and sorbitol to different value‐added products. The catalytic routes and mechanisms of each biomass‐derived platform compound are discussed and compared. In order to be feasible for large‐scale applications, low‐cost composition and preparation of electrocatalysts are mandatory and will be emphasized. Finally, our personal perspective on the current challenges and future directions of electrocatalytic biomass upgrading is presented.
Computational Modelling of Selectivity in Cobalt‐Catalyzed Propene Hydroformylation
Authors: Szlapa Ewa N. , Harvey Jeremy N. 
Published: August 2018

AbstractA mechanistic model for the cobalt‐catalyzed hydroformylation of propene, based on density functional theory and coupled cluster electronic structure calculations and transition state theory, is proposed to explain the experimentally observed reactivity and selectivity. The electronic structure calculations provide very accurate energies, which are used with transition state theory to compute rate constants; the kinetics of the network of coupled reactions are then modelled numerically for this organometallic reaction. The model accounts well for the dependence of rate on the concentrations of catalysts and reagents, and also on the temperature, and the agreement with experiment is improved still further upon making small adjustments to the ab initio calculated free energy values. The calculations provide detailed kinetic insight into the mechanism of hydroformylation and the role of various elementary steps in defining reactivity and selectivity.

Published: August 2018

BackgroundFor many childhood cancers, survival is lower among non‐Hispanic blacks and Hispanics in comparison with non‐Hispanic whites, and this may be attributed to underlying socioeconomic factors. However, prior childhood cancer survival studies have not formally tested for mediation by socioeconomic status (SES). This study applied mediation methods to quantify the role of SES in racial/ethnic differences in childhood cancer survival.MethodsThis study used population‐based cancer survival data from the Surveillance, Epidemiology, and End Results 18 database for black, white, and Hispanic children who had been diagnosed at the ages of 0 to 19 years in 2000‐2011 (n = 31,866). Black‐white and Hispanic‐white mortality hazard ratios and 95% confidence intervals, adjusted for age, sex, and stage at diagnosis, were estimated. The inverse odds weighting method was used to test for mediation by SES, which was measured with a validated census‐tract composite index.ResultsWhites had a significant survival advantage over blacks and Hispanics for several childhood cancers. SES significantly mediated the race/ethnicity–survival association for acute lymphoblastic leukemia, acute myeloid leukemia, neuroblastoma, and non‐Hodgkin lymphoma; SES reduced the original association between race/ethnicity and survival by 44%, 28%, 49%, and 34%, respectively, for blacks versus whites and by 31%, 73%, 48%, and 28%, respectively, for Hispanics versus whites ((log hazard ratio total effect – log hazard ratio direct effect)/log hazard ratio total effect).ConclusionsSES significantly mediates racial/ethnic childhood cancer survival disparities for several cancers. However, the proportion of the total race/ethnicity–survival association explained by SES varies between black‐white and Hispanic‐white comparisons for some cancers, and this suggests that mediation by other factors differs across groups.
