Solubilisation comparée des silicates, carbonates et hydroxydes en fonction des conditions du milieu
Authors: Robert Michel , Veneau Georges , Berrier Jeanine 
Published: November 2019

L'application des études sur la dissolution dans le domaine de la biosphère implique la prise en compte de conditions variées : eau pure mais aussi eau acide (pH entre 3 et 5) ou contenant des anions complexants.
Des exemples sont pris illustrant le comportement des principaux minéraux primaires (mica, feldspath, olivine, calcite, dolomite) et secondaires qui constituent la fraction argile des sols (phyllosilicates, oxydes, hydroxydes). Dans ces conditions la dissolution apparaît différente de celle provoquée par l'eau pure, à la fois sur le plan quantitatif (intensification par un facteur de 10 ou 100) et qualitatif (libération importante de l'aluminium). La stabilité des minéraux apparaît très dépendante des conditions physicochimiques et hydrodynamiques du milieu.
Méthodes d'étude des phénomènes d'ordre et de désordre par diffraction de rayonnements
Authors: Bergevin François de 
Published: November 2019

On traite ici de l'étude, par diffusion et diffraction, des corps désordonnés dans lesquels subsiste un réseau moyen périodique, étendu à l'infini ; le désordre consiste en des écarts (de substitution ou de déplacement) par rapport à ce réseau. Historiquement, ce problème a d'abord été abordé à propos des alliages, et ce sont les écoles de Warren et de Guinier qui ont développé les méthodes actuellement utilisées.
Le diagramme de diffusion se partage, dans l'espace réciproque, en deux composantes : l'une est « diffractée » en des pics discrets et représente la moyenne périodique de la structure, alors que l'autre, « diffusée » de façon continue, représente l'écart à cette moyenne. De cette dernière composante, on peut en principe extraire les paramètres d'ordre à courte distance qui décrivent les substitutions et les corrélations entre déplacements et substitutions. On décrit les avantages ou inconvénients qui inciteront à recourir à l'une des trois principales techniques : diffusion d'électrons, de neutrons, ou de rayons X. On évoque les montages utilisés dans ce dernier cas.
En chimie minérale, il n'est pas exceptionnel que l'on rencontre un ordre quasi parfait à courte distance, sans ordre à grande distance. Dans ce cas les figures de diffusion se condensent dans l'espace réciproque sur des surfaces ou des lignes. C'est le cas par exemple pour FeLiO₂, VC₀,₇₅, Ti[1-x]S₂, Cu[1-x]NbS₂, etc. Dans ces exemples, on peut décrire un amas ou une figure locale qui se produit dans toute la structure, mais sans respecter de symétrie de translation.
On donne quelques exemples d'études d'ordre à courte distance, concernant des composés de type spinelle ou fluorine.

Détermination des paramètres d'ordre et de désordre dans quelques solides à structure lamellaire (silicates, carbones)
Authors: Tchoubar Cyril 
Published: November 2019

Un minéral à structure lamellaire présente une cohésion cristalline très forte dans deux dimensions et faible dans la troisième, correspondant à un empilement de feuillets.
Pour décrire le phénomène de diffraction produit par un tel système, il est commode de considérer séparément les ondes diffusées par chaque feuillet, l'empilement des feuillets se traduisant par l'interférence de ces ondes diffusées. Pour un empilement de M feuillets parallèles, l'intensité diffractée en un point caractérisé par le vecteur de diffusions s⃗ (|s⃗| = 2 sin θ / λ) s'écrit alors :
i(s⃗) ∝ ∑[pour n=0 jusqu'à n=M-1] (M-n)&lt;F(s⃗)F*n(s⃗)DD* exp (2πi s⃗rn⃗)>&gt;
où
rn⃗ repère la position d'un feuillet par rapport à son n-ième voisin,
F et Fn sont les facteurs de structure d'un feuillet et de son n-ième voisin,
D est la transformée de Fourier de la forme du domaine cohérent de diffraction,
&lt; &gt; indique qu'on prend la valeur moyenne du produit.
La plupart des minéraux lamellaires riches en défauts structuraux étant microcristallisés, on est amené à exploiter les données de diagrammes de poudre.
En utilisant le formalisme décrit précédemment et en tenant compte d'éventuelles orientations mutuelles partielles des particules dans la poudre, il est possible de déterminer les principales caractéristiques de défauts dans les minéraux lamellaires. La méthode consiste à calculer des profils de réflexions à partir de modèles d'empilement puis à ajuster ces profils aux profils expérimentaux. Des exemples pris parmi les silicates lamellaires et les carbones montrent qu'on peut ainsi étudier principalement :
— les fautes d'empilement des feuillets (rotation, translation),
— les fautes au sein des feuillets (défauts ponctuels, distorsions, etc...),
— la présence et la succession de feuillets de natures différentes (minéraux dits «interstratifiés »).
Enfin, une dernière partie montre comment la méthode du «lattice imaging » en microscopie électronique par transmission, à haute résolution, permet d'aborder directement les problèmes d'ordre-désordre dans les minéraux lamellaires.

Notes and Updates on the Typification of Some Cassia (Leguminosae: Caesalpinioideae) Names
Authors: De Moura Tânia M. , Gereau Roy E. , Tachevski Ana P. , Rando Juliana G. 
Published: November 2019

S. Irwin and R. C. Barneby made a significant contribution to the knowledge of Leguminosae, especially in the tribe Cassieae (Caesalpinioideae). Nevertheless, their work included use of some unconventional terms for type designations, i.e., lectoholotypus and neoholotypus, which do not appear in the International Code of Nomenclature for algae, fungi, and plants. Some authors have recognized them as lectotypes, and we interpret them as such. Analyzing the 53 names for which a “neoholotypus” was designated, we identified several other errors by Irwin and Barneby. These include citation of incorrect type collection numbers for Cassia atroglandulosa Taub. ex Harms and C. laxiracemosa Harms and of an incorrect herbarium acronym for C. catingae Harms and C. sincorana Harms. Here, we provide brief explanations to clarify these situations. A second-step lectotype is designated for C. repens Vogel. Finally, it is noted that the type designation of C. bradei Ekman ex Harms requires, at least, second-step lectotypification, which cannot be done until the herbarium at S becomes accessible.

Se llevó a cabo un estudio con alumnos del 3er. semestre de preparatoria del Instituto Tecnológico y de Estudios Superiores de Monterrey, Campus Toluca, en donde se investigaron los factores: autocontrol, habilidad social, promedio de secundaria, puntaje de la prueba de admisión al sistema ITESM y las calificaciones obtenidas durante los dos primeros semestres de la preparatoria bilingüe y bicultural, como variables que correlacionan con el rendimiento académico de los alumnos en la preparatoria. Se plantearon dos aspectos relevantes para llevar a cabo la investigación, en primera instancia, su probable contribución con la estructuración de programas de seguimiento académico para alumnos que obtengan puntajes límites al ingresar a la preparatoria y por otra parte, su posibilidad de identificar áreas de conocimiento para el rediseño de los programas de atención y desarrollo académico (PDA y PAA) en donde se brinda apoyo y asesoría a alumnos con dificultades escolares.
Mathematical models of unshadowing the wages
Authors: Martyniuk Olesia , Popina Stepan 
Published: November 2019

The article addresses a social and economic phenomenon of shadow economy, which is typical for many countries and may result in a macroeconomic imbalance. The latter hinders the sustainable growth of the economy and leads to state budget losses. Shadow economy is penetrating into almost all sectors of the national economy. As shown in the paper, a high level of shadow economy is a threat to the national economic security of the country and a cause of declining its competitiveness. The findings confirm that measuring the impact of some factors of shadow economy on the economic security of the country is quite difficult. However, there are some factors for which mathematical models can be built to describe a correlation between economic indicators and a certain factor of shadow economy. Since salary expenses constitute a significant portion of enterprise’s basic expenses, it is important to build mathematical models for calculating the correlation between shadow salaries and tax rates.Thus, the purpose of the article is to examine mathematical models of the correlation between official and shadow salaries and tax rates. The developed mathematical models demonstrate that a reduction of tax rates is followed by changes in a shadow part of salaries. The article describes a number of cases when there are no changes in salaries and tax revenues, as well as cases of pay increase.The analysis finally suggests ways to increase salaries and techniques to de-shadow salaries. The authors use general scientific methods of generalization, comparison, analysis, and the method of mathematical modeling.
The evolution of intangible assets in terms of social and economic development concepts
Authors: Yasyshena Valentyna 
Published: November 2019

The article presents evidence that historically the emergence of intellectual property rights dates back to the pre-industrial stage of society’s development. The issuing of letters patent in England led to further development of intangible assets worldwide. The study considers chronologically social and economic development concepts which have been researched in academic papers of prominent scholars, namely, A. Smith, F. List,Knight, F. Machlup, W. Rostow, J. Galbraith, D. Bell, P. Drucker, and then highlights the key aspects that have affected the evolution of intangible assets. Thus, on the basis of reviewing the concepts developed by outstanding scholars, it is pointed out that the growth of intangible assets has been driven by knowledge and that a post-industrial society is based on unprecedented technological breakthroughs. Special reference is made to information viewed as the key production resource of a post-industrial society, whereas knowledge is seen as its internal source of progress. In a post-industrial society, people are regarded as capital. The essential importance and role of intellectual capital in company operations are embodied in professional and managerial skills of personnel.As shown in the article, there are not only research development concepts, but also normative documents, such as the Bulletin entitled «Amortization of intangible assets», in which intangible assets are identified as accounting items. Furthermore, the international system of intellectual property protection has been enhanced by the introduction of Paris and Berne Conventions.The paper also describes how the concept of intangible assets, which appeared in Ukraine’s legislation in 1993, is seen in the national legal system, specifically as intellectual property objects including industrial property and other items of property and use. With the introduction of Ukrainian Accounting Standards (UAS) 8 into the national legislation, it was firstly emphasized that intangible assets are non-monetary assets that, on the one hand, are non-material and, on the other hand, can be identified.The article also stresses that today’s society is passing a new stage of post-industrial development, which is accompanied not only by a rapid growth of service industries, science and education, but also by a significant increase of specialized knowledge in various fields. Finally, the need for further research of intangible assets is identified, since intangibles have a great impact on enterprise value and the competitiveness of the national economy as a whole.

Adaptability of pregnant women toward labor preparation is very important. If the mother cannot adapt during the process of labor, usually she will experience anxiety and will give a response of fight or flight triggered by the abundance of Catecholamines hormones and by the presence of fear and other forms of distress. This research used a quasi experiment method with non randomized pretest potest equivalent group design, without intervention on the comparison group. The quetionnaire of Hamilton Anxiety Rating Scale was used to measure the level of anxiety among pregnant women given hypnosis therapy with pregnant women not given the hypnosis therapy. The results showed that there was a significant difference in the mean level of anxiety between cases and controls (SD of 6,004). There was a significant influence on the group that used hypnosis therapy with a mean decrease in anxiety by 21.550 poin with a p value of < 0.001. Therefore, hypnosis is effective in reducing anxiety among nulliparous women in the third quarter of pregnancy.

Authors: Suhaid Dewi Novitasari , Faranita Fransisca 
Published: November 2019

Immunization is an attempt to actively boost a person's immunity against a disease, so that if one day exposed to the disease will not get sick or just experience mild illness. Immunization is routinely divided into primary immunization and continued immunization. Basic immunization is given to infants aged 0 to 1 year, where as advanced immunization is a repeat immunization intended to maintain immunity level or to prolong the period of protection. Further immunization is given when primary immunization is given first, and is given at the age of toddlers and at school age.
This research is cross-sectional study. The dependent variable in this study is the basic immunization status of infants, while the independent variables include age, education level, occupation, knowledge and attitude. The sample of this research is mothers with children aged 12-24 months totaling 250 respondents. Instrument of data collection using questionnaire and health record of baby. The data transformation uses the data normality test and Rasch model. Data analysis technique using Chi Square test and logistic regression test.
The result of data analysis showed that there was a significant correlation between occupation (p <0,05, PR = 1,864; 95% CI = 1,121-3,097), education level (p <0,05; PR = 3,438; 95% CI = 1,671- 7,074), knowledge (p <0,05, PR = 2,653; 95% CI 1,580-4,455) and attitude (p <0,05, PR = 3,202; 95% CI = 1,897-5,405) with infant immunization status. Age has no significant relationship with the basic immunization status of infants.
Conclusions coverage of basic infant immunization completeness in this area is still low that is equal to 42,4%. Attitude is the most dominant factor associated with the basic immunization status of infants.

From reciprocity to collective empowerment: Re-framing university-school partnership discourses in the South African context
Authors: Silbert Patti 
Published: November 2019

While partnerships are key to sustained engagement between universities and schools, structural and historical differences exist between partners at the level of both organisational boundaries and socioeconomic borders. Differential relations, particularly accentuated in contexts such as South Africa, are frequently masked by normative assumptions that have largely remained unquestioned.
Reciprocity and mutuality are two such foundational concepts, regularly enlisted in the partnership literature. Applied uncritically, these concepts function to obscure power differentials between partnering institutions – and between people who bring to those partnerships different histories and social positions. Using the example of a South African university-school partnership, the article draws on the scholarship of Keith (2005), Stavro (2001) and Young (1990, 1997a, 1997b) to develop a framework that moves beyond reciprocity and mutuality towards collective empowerment and solidarity. This discursive shift reflects the complexities of partnerships and partnering – and opens the space for more authentic forms of engagement, particularly in unequal partnering contexts. The article offers insights, from the perspective of the particular case presented, into how dialogic spaces might be created for interrupting normative discourses and practices, and for re-imagining new possibilities for partnering across contexts of difference.
