Gyp-scale deposition in producing wellbores is a recognized problem in many West Texas oil fields. The results of gyp-scale formation are usually reduced producing rates, premature well abandonment, and high operating expenses. An effective gyp removal and inhibition program is necessary for successful operation where gyp-scaling problems exist. Development of the gyp-control program presently in effect in the Means (San Andres) Unit began in 1969 when gyp was originally detected in the Grayburg-San Andres reservoir of the Means Field in Andrews County, Texas. Prior to that time, a great deal of progress had been made in the area of gyp-scale control in the Means (Queen) reservoir which overlies the Grayburg-San Andres. This paper presents a description of the Means (San Andres) Unit Gyp Scale Control Program and the results achieved with that program.

The results of floristic classification of technogenic vegetation (alliance Chamerio angustifolii–Matricarion hookeri A. Ishbirdin et al. 1996, order Chamerio–Betuletalia nanae Khusainov et al. in Sumina 2012, class Matricario–Poetea arcticae A. Ishbirdin in Sumina 2012) conducted by the Braun-Blanquet method (Braun-Blanquet, 1964; Mirkin, Naumova, 1998) are given. 98 geobotanical relevés, made in 1981–2013 on areas of oil fields and suburbs of the Usinsk city (Komi Republic) (56–60о N, 67–66о E), were involved into analysis (Fig. 1). The ecological parameters like moisture (F) and mineral nitrogen soil enrichment (N) were assessed using the Ellenberg ecological scales (Ellenberg, 1974).

Abstract This article's goal is to present some of the main flow assurance challenges faced by PETROBRAS in the Buzios oil field, from its early design stages to full operation, up to this day. These challenges include: hydrate formation in WAG (Water Alternating Gas) operations; reliability of the chemical injection system to prevent scale deposition; increasing GLR (Gas Liquid Ratio) management and operations with extremely high flowrates. Flow assurance experience amassed in Buzios and in other pre-salt oil fields, regarding all these presented issues, is particularly relevant for the development of future projects with similar characteristics, such as high liquid flow rate, high CO2 content and high scaling potential.

The text of this article emphasizes that the history of transplantation as an independent medical industry originated in the Union of Soviet Socialist Republics, the first successful operation to transplant human organs and tissues was performed there by the surgeon Yuri Voronoy. Today Russia is one of the world-leading powers where human organ and tissue transplant operations are performed. Among all the subjects of Russia where transplant operations are carried out, Sverdlovsk region occupies a special place: doctors in this region conduct successful operations on organ and tissue transplantation and make discoveries that are significant for Russian transplantology. The study of Russian laws and regulations regulating relations in the field of transplantology conducted by authors, as well as an analysis of the scientific literature showed that relations in the field of transplantology are not fully regulated by Russian legislation, including criminal law. On the territory of Sverdlovsk region in particular, as well as on the territory of Sverdlovsk region as a whole, it is possible, for example, to carry out transactions for the sale and purchase of human organs and tissues with impunity, if such transactions are not related to causing harm to the life and health of the victim. These deals are illegal, but not punishable. As the analysis of the practice carried out in the framework of this study has shown, the inhabitants of Sverdlovsk region suffered from the imperfection of the norms of Russian legislation regulating relations in the field of transplantology. While the residents of Sverdlovsk region are suffering from illegal transplantation, one cannot speak of the sustainable development of this region. The authors of the study, in order to combat illegal transplantation in Sverdlovsk region, propose that the regional authorities strengthen measures to improve the general legal literacy of the population, introduce a register of citizens' opinions on the posthumous transplantation of their organs and tissues, and introduce mandatory registration of transactions made in Sverdlovsk region, a subject of which are human organs and tissues.

Este trabajo hace referencia a la oportunidad que puede representar la educación intercultural para la resignificación de las identidades de género, etnia y clase. Se reflexiona a partir de la investigación sobre educación realizada en el municipio de San Andrés Larráinzar o Sakamch’en de los Pobres, Chiapas. A partir de los resultados de investigación se argumenta que en el contexto actual en que se está practicando la educación intercultural bilingüe en Chiapas y en el marco de políticas educativas que no son construcciones propias de los pueblos indígenas significan nada más nuevas imposiciones simuladas con los discursos de respeto a la diversidad cultural.   SUMMARY This paper refers to the opportunity that can represent the intercultural education for re-meaning the gender, class and ethnic identities. The work is a reflection from the investigation made in the municipality of San Andrés Larráinzar or Sakamch’en in Chiapas. From the results of investigation is argued that in the present context that the intercultural bilingual education is practicing in Chiapas and in the context of educational policies are not people’s own constructions, mean nothing more new impositions simulated with the speeches of respect for cultural diversity.
