Predictores del bienestar psicológico de los estudiantes universitarios de arte y cultura

The study investigated the predictors of psychological well-being of the art and culture of university students. Predictors of psychological well-being are psychological culture and its psychological variables: the ability to reflect, the ability to be a subject (subjectness) and creativity. This was an empirical study that collected data through a questionnaire. The results of the research showed the influence of psychological culture on the level of well-being of the University students. Personal variables “subjectness”, “reflexivity” and “creativity” were used in the regression analysis to predict the values of the variable “psychological well-being”. It is established that these variables are predictive: their severity is a prognostically significant feature in the analysis of the psychological well-being of the art and culture of university students. Reflexivity means the strongest prediction in relation to the level of psychological well-being.El estudio investigó los predictores del bienestar psicológico del arte y la cultura de los estudiantes universitarios.

Phase boundary texturing influence on laminated compound durability under local thermal effect

Destruction process modeling has been conducted for a laminated material under a local pointed thermal effect. Temperature field dependence on the coating surface texturing parameters has been studied. A mathematical model of the load distribution in the laminated material with wavy coating surface texturing under thermal effect is presented

English borrowings in the Spanish language: language policy of the Royal Academy of the Spanish language and the Fundéu BBVA regarding anglicisms

We can observe a rather purist attitude of certain Spanish institutions towards the use of anglicisms in the Spanish language.This difference in attitudes towards openness to other languages between the various countries may be explained by, among other things, the existence of linguistic institutions such as the Royal Academy of the Spanish Language (La Real Academia Española) and the Foundation of Urgent Spanish (Fundéu BBVA), which, according to many researchers, follow a restrictive policy against the use of anglicism

Біопротекторна дія цинку в макро- і наноаквахелатній формі на ембріогенез щурів за умови свинцевої інтоксикації

The article presents results of studied influence of low doses of lead and zinc (nanozinc) on embryonal development in a la­boratory experiment on rats.  Negative influence of lead on pregnancy of laboratory animals, manifested in violation of the physiological dynamics of the rectal temperature and decrease in body weight gain was revealed. Embryotoxic ef­fect of low doses of lead results in increased fetal mortality by 2.16 times compared to the control group of animals, de­terioration of the morphometric indices of fetuses, violation of placentogenesis. Simultaneous injections of zinc on back­ground of lead intoxication causes a protective effect on the body of pregnant rats and embryonal development of the offspring, more pronounced for zinc citrate, received by using aquananotehnology, as compared to zinc chloride. Thus, by morphometry indices, male fetuses were more sensitive to prenatal lead exposure in comparison to female fetuses.В статье представлены результаты изучения воздействия низких доз свинца и цинка (наноцинка) на эмбриональное развитие в условиях лабораторного эксперимента на крысах. Установлено негативное вли­яние свинца на протекание беременности у лабораторных животных, что проявляется в нарушении физио­логической динамики ректальной температуры и снижении прироста массы тела. Эмбриотоксический эффект низких доз свинца проявляется в увеличении эмбриональной смертности в 2,16 раза по сравнению с кон­трольной группой животных, ухудшении морфометрических показателей плодов, нарушении плацен­тогенеза. Одновременное введение препаратов цинка при свинцовой интоксикации оказывает протекторное действие на организм беременных крыс и эмбриональное развитие потомства, более выраженное для цит­рата цинка, полученного с использованием аквананотехнологии по сравнению с хлоридом цинка. При этом по морфометрическим показателям плоды мужского пола оказались более чувствительны к пренатальному воз­действию свинца по сравнению с плодами женского пола. The article presents results of studied influence of low doses of lead and zinc (nanozinc) on embryonal development in a la­boratory experiment on rats.  Negative influence of lead on pregnancy of laboratory animals, manifested in violation of the physiological dynamics of the rectal temperature and decrease in body weight gain was revealed.

A Practical, One-Pot Synthesis of Highly Substituted Thiophenes and Benzo[b]thiophenes from Bromoenynes and o-Alkynylbromobenzenes

An efficient synthesis of thiophenes and benzo[b]thiophenes has been developed from easily available bromoenynes and o-alkynylbromobenzene derivatives. This novel one-pot procedure involves a Pd-catalyzed C–S bond formation using a hydrogen sulfide surrogate followed by a heterocyclization reaction. Moreover, in situ functionalization with selected electrophiles further expands the potential of this methodology to the preparation of the corresponding highly substituted sulfur heterocycles.Junta de Castilla y Leon (BU021A09 and GR-172) and Ministerio de Ciencia e Innovacion (MICINN) and FEDER (CTQ2010-15358 and CTQ2009-09949/BQU) for financial support.

Tuning the electrical conductance of metalloporphyrin supramolecular wires

In contrast with conventional single-molecule junctions, in which the current flows parallel to the long axis or plane of a molecule, we investigate the transport properties of M(II)-5,15-diphenylporphyrin (M-DPP) single-molecule junctions (M=Co, Ni, Cu, or Zn divalent metal ions), in which the current flows perpendicular to the plane of the porphyrin. Novel STM-based conductance measurements combined with quantum transport calculations demonstrate that current-perpendicular-to-the-plane (CPP) junctions have three-orders-of-magnitude higher electrical conductanc than their current in-plane (CIP) counterparts, ranging from 2.10−2 G0 for Ni-DPP up to 8.10−2 G0 for Zn-DPP. The metal ion in the center of the DPP skeletons is strongly coordinated with the nitrogens of the pyridyl coated electrodes, with a binding energy that is sensitive to the choice of metal ion. We find that the binding energies of Zn-DPP and Co-DPP are significantly higher than those of Ni-DPP and Cu-DPP. Therefore when combined with its higher conductance, we identify Zn-DPP as the favoured candidate for high conductance CPP single-molecule devices
