Authors: Montes de Oca Erika Román , Licea Resendiz Jesús Eduardo , García Hernández José Luís 
Published: October 2019

El presente estudio se llevó a cabo en la comunidad de Huajintlán, Morelos, México. Su objetivo fue conocer la opinión de los actores de la comunidad sobre las actividades realizadas mediante la vinculación con los estudiantes del Sistema de Integración al Medio Rural (SIMR). Se realizó una investigación de tipo cualitativa con la aplicación del método fenomenológico; la muestra se compuso de 30 personas, hombres y mujeres, cuyas edades oscilaban entre 24 y 65 años. Para la recolección de datos se utilizó un instrumento con 17 ítems, el cual se aplicó a los pobladores de la comunidad que participaron en el desarrollo de las actividades con los alumnos.
Los resultados arrojaron que la primordial forma de inserción hacia la comunidad por parte de los estudiantes del SIMR se dio a través de las acciones realizadas con los niños que cursaban la primaria (84 %). Las principales actividades que llevaron a cabo los participantes de la comunidad con los estudiantes fueron la elaboración de mermeladas, mazapán y nieve (53 %), las cuales representaron una alternativa para generar ingresos, contribuir al gasto familiar y propiciar un intercambio de saberes entre los educandos y los habitantes de la comunidad; asimismo, manifestaron su disposición para contratar un estudiante una vez que egrese. El binomio vinculación-interacción está presente dentro de las actividades contempladas en la unidad de aprendizaje del SIMR de la Licenciatura en Desarrollo Rural. A través de este proceso se generaron beneficios y necesidades, los cuales son considerados como parte de los métodos que fomentan el crecimiento y desarrollo de los participantes mediante el contraste, la relación y la aplicación de la información recibida en el aula contra lo que está pasando en un escenario real en la comunidad.

Published: October 2019

Abstract
In this study, LaxMoyOz powders were synthesized by a cost-effective solid-state synthesis method. Four different heating cycles were designed to investigate the effects of synthesis temperature and holding time on lanthanum molybdate (LMO) formation, phase assemblies, particle size and morphology. X-Ray Diffraction (XRD) and scanning electron microscopy (SEM) studies were performed to observe crystal structure and particle morphology of synthesized powders. The results showed that nearly ninety percent β - La2Mo2O9 (43,3 nm crystal size) phase was obtained at 1000 °C for 6 h holding time. Longer holding times at 1000 °C favor more oxygen-rich compounds which cause recrystallization of various new crystalline phases. The grain size of the synthesized powder was increased from 0,2 µm to 1,5 µm with increasing holding time. In summary, it is possible to manufacture LMO powders rich in β - La2Mo2O9 by one - step solid - state synthesis method. The phase assembles and particle size of LMO powders could also be tailored by optimization of heat treatment cycle.

Authors: Żurakowska-Sawa Joanna 
Published: October 2019

Summary

Subject and purpose of work: The purpose of the study is to determine the variables determining the level of synthetic measure of economic efficiency in listed companies of the industry sector as part of their enterprise life cycle.

Materials and methods: The article uses data from annual unitary financial statements of industrial enterprises according to the classification of the Warsaw Stock Exchange and data describing the macroeconomic situation of the state economy. The research period covered the years 1999-2012. In order to examine which factors determine the level of economic efficiency at each stage of the life cycle of enterprises, estimation of econometric models was carried out.

Results: In the models obtained for companies in the growth and maturity stage, statistically significant determinants were obtained only in the field of internal factors. In the models estimated for companies in the stages of launch, shake-out and decline, statistically significant conditions were identified, both in terms of external factors and in the area of internal factors.

Conclusions: A comprehensive assessment of the conditions for the level of economic efficiency of enterprises should take into account both factors dependent on the enterprise (microeconomic) as well as those determined by the environment (macroeconomic) and beyond its control. It is therefore necessary for managers of enterprises to have extensive and up-to-date knowledge of factors and conditions that are significant in shaping the level of economic efficiency.

Abstract
The textile industry is still significantly involved in production and employment in developed countries and is a major source of growth in many developing countries. As a business with a long history, the textile industry undergoes radical transformations at a global level. With the emergence of new competitors, global business conditions have changed significantly. Nevertheless, European manufacturers have remained world leaders in the production of industrial textiles and fashion clothing. Many European manufacturers resort to subcontracting or relocating capacity for labour-intensive activities in countries with lower labour costs, such as Serbia, in order to maintain competitiveness. The greatest success of the domestic textile industry was recorded in the late 1980s when it was a significant source of employment, the creation of added value and more balanced regional development. Although it is still not at the level of the 1980s, positive developments in the domestic textile industry appeared in 2016 in the direction of growth in production, employment and exports. The state seeks to accelerate the development of the textile industry through the subsidisation of foreign and domestic investors. However, growth that is primarily based on foreign direct investment is a long-term unsustainable concept. In order for growth to be sustainable, it is necessary to encourage the development of activities that produce greater added value and increase competitiveness. That is the reason why it is necessary to support the development of domestic enterprises, as well as the arrival of those foreign investments that generate multiple levels of added value.

Authors: Spapen Herbert , van Laethem Johan , Hites Maya , Verdoodt An , Diltoer Marc , Honoré Patrick M. 
Published: October 2019

Abstract

Background and Objectives
High-dose colistin (COL) ensures adequate treatment of pneumonia caused by multidrug resistant gram-negative bacteria (MDR-GNB) but must be weighed against a higher risk of nephrotoxicity. Continuous veno-venous hemofiltration (CVVH) clears COL by filtering and membrane adsorption that permits to avoid dose accumulation and excessively high peak concentrations. We evaluated clinical/microbiological efficacy of the high-dose COL treatment under CVVH in patients with newly diagnosed MDR-GNB ventilator-associated pneumonia (VAP).

Methods
Observational cohort study in critically ill adult patients with MDR-GNB VAP. Colistimethate sodium (CMS) was administered as a 9 million international units (MIU) of loading dose followed by 3 × 4.5 MIU daily. CVVH was performed over a highly adsorptive membrane. Clinical and microbiological efficacies were assessed at the end of therapy. In survivors, serum creatinine level was evaluated before and at the end of therapy.

Results
Fourteen patients (8 male patients, aged 57 ± 14 years) were consecutively included. Isolated pathogens were Pseudomonas aeruginosa in 7, Klebsiella pneumoniae in 5, and other Enterobacteriaceae in 2 patients. A favorable clinical response was observed in 9 patients (64%). Full and presumed microbiological eradication was observed in 12 patients (86%). Two patients were diagnosed with Stage 1 acute kidney injury.

Conclusions
In patients with MDR-GNB VAP, CVVH may represent an interesting option to enable effective high-dose COL treatment.

Abstract
Porous metal augments have been used successfully for management of large acetabular defects during revision hip arthroplasty. This study analyzes and compares the clinical and radiographic outcomes of porous metal augments in cemented and uncemented acetabular revisions, all performed at the same institution. In the period 2015-2017, 36 patients with 37 large acetabular defects were treated with porous metal augments in cemented and uncemented acetabular revisions. Postoperatively, patients were monitored for two years on average period of 24-36 months.
Acetabular augments were used when preoperative and intraoperative findings indicated the presence of large acetabular defects that can hinder the stability of the revision implants. We used lateral approach, 36 mm femoral head, and cementless or cemented acetabular cup depending on local bone quality. Postoperatively, all patients followed total hip arthroplasty precautions, with weight bearing as tolerated regimen with use of crutches during 6 weeks after surgery. The follow-up was radiological and clinical. We used HHS. At a mean follow-up of two years (range 24-36 months) one patient had reinfection and one patient had infection. None of the patients shown signs of aseptic augment or acetabular cup loosening. Porous metal augments show comparable excellent radiographic and clinical short-term outcomes, when combined with cemented or uncemented cups in revision hip arthroplasty. They allow good bone ingrowth, adequate implant contact and good stability. Complications were related to infection and not related to the augments itself.
Selected Aspects of the Management of Real Estates Owned by Legal Persons of Churches and other Religious Associations
Authors: Cienciała Agnieszka 
Published: October 2019

Abstract
At the end of 2012, there were 174 churches and religious associations operating in Poland (GUS 2014). Most of the individuals (nearly 96%) are the followers of the Roman Catholic Church. The Catholic Church and its organizational units have legal personality, thereby enabling them to acquire, possess and dispose of the title to real estate and other property rights, and administer the properties. In the years 1944-1962, almost all ecclesiastical real estates were nationalized. The asset-related situation of church legal persons was regulated upon the entry into force of the Act of 17 May 1989 on the relations between the State and the Catholic Church in the Republic of Poland. In 1991-2004, the legislator also regulated the legal status of many other churches and religious associations. Moreover, a fairly uniform system of ecclesiastical reprivatization was developed.
For the purposes of the publication, analyses of selected aspects concerning the management of real estates owned by legal persons of churches and other religious associations in Poland have been carried out. Cases of the approaches adopted in other exemplary countries have also been presented. The intention is to indicate the rules in force as well as the problems encountered in this regard.
Slope position and management practices as factors influencing selected properties of topsoil
Authors: Šimanský Vladimír , Juriga Martin , Mendyk Łukasz 
Published: October 2019

Abstract
An interaction between the slope position and type of soil management practices could be one of the most important factor affecting several soil properties including soil structure. Therefore, we evaluated selected soil properties including soil structure parameters in relation to slope gradient and soil management practices between Trakovice and Bučany villages (western Slovakia). The sampling sites were located in two adjacent, gently sloping fields with a NW-SE orientation. The sites also differ in soil management type: Field No. 1 was used as arable land with intensive cultivation (IC) of crops, while a greening system (GS) had been established on Field No. 2. Soil samples were taken from five geomorphological zones at each slope: summit, shoulder, back-slope, toe slope and flat terrain under the slope. Results showed that soil pH, content of soil organic matter (SOM) and carbonates depended on land use of the slopes. In GS, the water-stable macro-aggregates (WSAma) 0.5–3 mm (favourable size fraction) displayed statistical significant quadratic polynomial trend along the slope gradient. In IC the values of mean weight diameter of dry sieved aggregates (MWDd) decreased significantly along the slope gradient, while in GS the opposite trend was observed. In IC significant correlations between carbonates content (r=-0.775, P<0.01), humic acids (HA) content (r=0.654, P<0.05), colour quotients of humic substances (r=-0.706, P<0.05), colour quotients of HA (r=-0.723, P<0.05) and MWDd were determined. In GS higher content of carbonates was followed by a decrease in content WSAma, MWDd, mean weight diameter of wet sieved aggregates (MWDw) and stability index of aggregates. At the same time stabile and labile soil organic matter improved soil structure parameters in GS.
Vertisols properties and classification in relation to parent material differentiation near Strzelin (SW Poland)
Authors: Dudek Michał , Waroszewski Jarosław , Kabała Cezary , Łabaz Beata 
Published: October 2019

Abstract
Vertisols are characterized by high content of clay fraction that affects their specific morphological and physical features. The shrink-swell phenomena of clayey materials under specific moisture regime cause formation of cracks, wedge-shaped structural aggregates and slickensides on aggregate surfaces. It was formerly believed that these soils can be found only in tropical/subtropical zones, thus Vertisols have not been expected to form under temperate climate of Central Europe. As a result, Vertisols are insufficiently recognized and documented on soil maps in Poland, including the Lower Silesia region. The aim of this study was to examine soils developed on clayey parent materials near Strzelin, focusing on their morphology, properties and classification issues. There was confirmed that soils developed from Neogene clays have vertic and mollic horizon, accompanied by stagnic or gleyic properties. However, not all soils fulfil the criteria for Vertisols due to the presence of surface or subsurface coarser-textured (sandyor silty-textured) layers. Native differentiation of parent material and geomorphological processes were found the main factors, which control the spatial mosaic of Vertisols and black earths (Chernozems or Phaeozems).
