Published: June 2020

Los subproductos sólidos de carácter orgánico generados por los procesos de tratamiento de aguas residuales municipales son utilizados comúnmente como fuente de nutrientes para tratamiento de suelos. Estos biosólidos contienen nutrientes contaminantes inorgánicos como el mercurio, el cual es empleado para el estudio, por el conocimiento ampliamente documentado de su toxicidad en sistemas vivos y sus efectos en seres humanos. En este mismo sentido y puesto que las plantas constituyen la base de la cadena trófica, se centra la atención sobre el pasto, debido a su fácil crecimiento y uso como pastura de ganadería. El mercurio en pasto fue cuantificado mediante espectrofotometría de absorción atómica utilizando la técnica de generador de hidruros con vapor frío. Se verificaron algunos parámetros de validación con criterios de aceptación deseables tales como linealidad (r2 = 0,999), exactitud (R = 93,14-96,12%), precisión (CV = 1,11-1,69%), límites de detección y cuantificación (0,001-0,003 ppb). Se evidenció que las concentraciones de mercurio se encuentran por debajo de los valores máximos permitidos por la normatividad Internacional, presentando el biosólido como fuente confiable de nutrientes para el agro. De esta forma se establece una metodología que puede ser una buena herramienta para la determinación analítica de mercurio en pastos.

Authors: Veselovskiy Mikhail Yakovlevich , Pogodina Tatiana Vitalievna 
Published: June 2020

The article explores the sources and factors of forming the competitive advantages and competitiveness of companies based on the systematic implementation of intellectual leadership. The methodological basis of the research includes the theory of competency-based approach, innovative and strategic management. The research information base includes the official data from the Federal State Statistics Service, Russian manufacturing companies and the own scientific research findings. The research results include systematizing the new competitive advantages
of companies formed on the basis of intellectual leadership (corporate culture, managing
a knowledge system about key stakeholders, smart manufacturing, artificial intelligence) and key competencies. The pyramid of intellectual leadership is presented, which allows companies to build a personnel management strategy taking into account the gradual transition from the business management to collective management, and then to the spiritual leadership. The key competencies are identified and analyzed; they allow to increase the innovative activity of industrial enterprises (Research and Production Corporation United Wagon Company, PJSC; Novolipetsk Metallurgical Plant, PJSC; Red October, PJSC). It has been found that in Russia the large metallurgical and car manufacturing companies, food production companies are actively using modern digital technologies (electronic trading platforms, online stores, electronic document management, electronic procurement, online services for customers, electronic procurement for the needs of the enterprise, etc.) for developing their key competencies. In modern conditions digitalization of business processes is becoming an increasingly independent production resource and a key competency
of companies contributing to the achievement of strategic development goals. There are considered the operating and emerging clusters in the field of information technologies that can contribute to solving the problems of accelerated digitalization of the economy in the Novgorod region, in the Perm Territory, in the Republic of Tatarstan, and the cluster of information and communication technologies in the Rostov Region.
Methods of improving personnel management at enterprise as factor of labor efficiency and productivity
Authors: Nikolaev Nikolay Alekseevich 
Published: June 2020

The paper highlights the relevance of increasing the labor efficiency of personnel at the enterprise level. The level of labor productivity at Russian industrial enterprises is found several times lower than at the enterprises in the United States of America. There has been carried out a review of modern Russian scientific and methodological literature to evaluate the effectiveness of the personnel management systems. A significant number of methodological tools for assessing and improving the personnel management system of the enterprise have been identified. At the same time, there are no studies of methods assessing the personnel management systems ensuring the key properties of the personnel, which is especially important for the survival, increase of competitiveness and enterprise development in a highly competitive innovation environment. There has been presented the methodical approach to the assessment and improvement of the personnel management system of the enterprise as a factor in increasing the productivity and efficiency of labor. The criteria and indicators for assessing the personnel management system of the enterprise are developed. The key properties of the personnel management system are the goal-directedness of the personnel’s activities, the level of motivation to achieve the goals of the enterprise, the coordination
of staff interaction, the correspondence of the quantity and quality of personnel to the requirements for the performance of labor functions and the goals of the enterprise, and the quality of personnel labor management. The author’s approach to assessing the type of social and labor relations of staff based on the ratio of values, interests, coordination of interaction and socio-psychological working conditions is formulated. There has been revealed an empirical dependence of the impact of the state of the personnel management system on performance indicators, personnel labor productivity, as well as the dynamics of the enterprise. Based on the studies, a direct empirical dependence
of personnel performance factors on the integral indicator of the state of the personnel management system was established. The results of testing methodological recommendations on improving the personnel management system at the enterprise using the author's approach are presented.

Published: June 2020

The article describes the development of scientific and methodological recommendations of control over training highly qualified specialists in building information modeling (BIM) technology in the investment and construction sectors. The conceptual framework of BIM technology and its sub-processes are considered; the technical and economic advantages of practical application of information modeling are noted. BIM technologies are already used by a few Russian design and construction companies that develop their own BIM standards. In Russia the inevitability of moving architectural and construction activities, such as design, construction and operation
of buildings and structures, to BIM technologies has been shown. The transition is proved to be hindered by the lack of national BIM standards, insufficient participation of the state in the indus-trial implementation of BIM technologies, as well as a shortage of qualified personnel with the necessary competencies in the field of information and communication technologies. There has been pointed out the emergence of new construction professions, whose labor functions are directly related to the practical application of BIM technologies, as a response to the modern market requirements. The analysis of the labor market has been done, the analysis results have been used to make a conclusion about the shortage of engineering and management personnel in the domestic investment and construction complex. To eliminate the gap between the complex's need for qualified personnel and the volume of their supply in the labor market there have been formulated
a number of scientific and methodological recommendations, in particular, it has been proposed to create a state BIM educational center in which with the participation of Russian and foreign ex-perts, representatives of the investment and construction sector and software companies, profes-sional development of teachers and leading specialists in the construction industry will be carried out. To adapt to the requirements of digitalization of the industry, it is proposed to introduce the team work technologies into the educational process using BIM when mastering special engineer-ing disciplines and preparing the final qualification works. At the same time, the importance of in-tegrating the companies that develop specialized software, enterprises of the investment and con-struction complex, higher education organizations and public authorities in the transition of the in-vestment and construction complex to an innovative development path is emphasized.
Mujer y educación en la China actual
Authors: NIE NAN 
Published: June 2020

La educación de la mujer en China ha sufrido importantes procesos de cambio a lo largo de su milenaria historia. Inicialmente se encontraba caracterizada por el predominio de una sociedad feudal que obligaba a su reclusión en el hogar adoptando una posición de sumisión hacia el hombre y cuyo aprendizaje era el resultado de la transmisión de tradiciones y costumbres de madres a hijas. A partir del siglo XIX y tras el contacto cultural con las sociedades occidentales, comienzan a producirse cambios sustanciales que favorecen su participación en la sociedad y en la vida educativa. Cambios que van a tener su mayor alcance a partir de la creación de la República Popular de China y la Constitución, pues a partir de entonces es cuando podemos confirmar su incorporación al ámbito de la educación superior. A pesar de todo, las viejas reminiscencias machistas que todavía continúan generando prejuicios y estereotipos que en nada facilitan la plena incorporación laboral y educativa y las diferencias que se producen entre las distintas regiones que conforman el país, continúan siendo aún hoy dos grandes obstáculos que frenan el avance de la discriminación social y educativa femenina.

Abstract

OBJECTIVE
To determine the thermal antinociceptive effects of butorphanol tartrate and butorphanol tartrate in a sustained-release 25% poloxamer 407 (P407) gel formulation (But-P407) in parrots.

ANIMALS
13 orange-winged Amazon parrots (Amazona amazonica).

PROCEDURES
First, butorphanol tartrate (5 mg/kg) or saline (0.9% NaCl) solution was administered IM to birds in a randomized complete crossover design. The temperature prompting a foot withdrawal response to a thermal stimulus (ie, the thermal threshold) was determined 30 minutes before (baseline) and at various points after treatment administration. Second, But-P407 (12.5 mg/kg) or P407 was administered SC in a similar crossover design. Thermal threshold was determined before and at various points after treatment administration. Third, But-P407 (12.5 mg/kg) or saline solution was administered SC and evaluated as in the second trial. Sedation was scored immediately before each time point in all 3 trials.

RESULTS
In the first trial, a significant increase in thermal threshold was noted 30 minutes after butorphanol tartrate (vs saline solution) administration. No sedation was noted. In the second and third trials, no significant difference was identified between results for But-P407 and those for either control treatment (saline solution or P407). Mild sedation was noted in the second trial following But-P407 administration.

CONCLUSIONS AND CLINICAL RELEVANCE
Results suggested a small but significant thermal antinociceptive effect of butorphanol tartrate lasting between 30 minutes and 1.5 hours in orange-winged Amazon parrots. No antinociceptive effect of butorphanol tartrate was demonstrated when delivered in P407. Further research is needed to evaluate the potential analgesic effects of But-P407.
Assessment of luteinizing hormone receptor expression in structural support tissues of canine hip and femorotibial joints
Authors: Kiefel Claire A. , Kutzler Michelle A. 
Published: June 2020

Abstract

OBJECTIVE
To determine whether luteinizing hormone receptors (LHRs) are expressed in canine femoral head subchondral bone (FHSB), hip joint round ligament (RL), cranial cruciate ligament (CCL), and femorotibial joint synovium (FJS) specimens.

SAMPLE
1 specimen each of the FHSB, RL, CCL, and FJS obtained from the left hind limbs of 19 fresh canine cadavers.

PROCEDURES
1 section of each FHSB, RL, CCL, and FJS specimen was processed with rabbit polyclonal IgG anti-human LHR antibody, and 1 section was treated with negative control reagents. Percentage immunoexpression of LHRs in FHSB and FJS sections was analyzed by assessment of 100 bone marrow cells or synoviocytes in 3 adjacent hpf (400×). In each RL and CCL section, immunoexpression of LHRs in fibrocytes was semiquantitatively analyzed on the basis of the mean of the product of percentage staining score (from 0 [no staining] to 3 [> 50% of cells stained]) and staining intensity score (from 0 [no staining] to 2 [moderate to strong staining]) for 3 adjacent hpf.

RESULTS
All tissues examined had variable LHR expression. Expression of LHRs in FHSB, CCL, or FJS specimens did not differ between sexes or between sexually intact and gonadectomized dogs. However, RL specimens from female dogs had significantly greater LHR expression scores, compared with findings for male dogs.

CONCLUSIONS AND CLINICAL RELEVANCE
Results indicated that LHRs are expressed in structural support tissues of canine hip and femorotibial joints. Further research is required to determine the LHRs' function, mechanism of action, and potential contribution to the pathogenesis of hip dysplasia or CCL rupture in dogs.

Abstract

OBJECTIVE
To compare analgesic efficacy and fetal effects between transdermal administration of fentanyl and IM administration of buprenorphine in pregnant sheep.

ANIMALS
12 healthy pregnant ewes.

PROCEDURES
Before study initiation, each ewe was confirmed pregnant with a single fetus between 113 and 117 days of gestation. Ewes were randomly assigned to receive buprenorphine (0.01 mg/kg, IM, q 8 h for 48 hours beginning 1 hour before anesthesia induction; n = 6) or fentanyl (a combination of transdermal fentanyl patches sufficient to deliver a dose of 2 μg of fentanyl/kg/h applied between the dorsal borders of the scapulae 24 hours before anesthesia induction; 6). Ewes were anesthetized and underwent a surgical procedure to instrument the fetus with an arterial catheter and place a catheter in utero for collection of amniotic fluid samples. Physiologic variables and behavioral changes indicative of pain were assessed, and amniotic fluid and blood samples from ewes and fetuses were collected for determination of drug concentrations at predetermined times.

RESULTS
Both protocols provided acceptable postoperative analgesia with no adverse effects observed in the ewes or fetuses. Compared with the buprenorphine protocol, the fentanyl protocol induced more profound analgesia, decreased the requirement for isoflurane during surgery, and was associated with a shorter anesthesia recovery time. Fetal indices did not differ significantly between the 2 analgesic protocols.

CONCLUSIONS AND CLINICAL RELEVANCE
Results indicated that both protocols provided acceptable analgesia. However, the fentanyl protocol was superior in regard to the extent of analgesia induced, inhalant-sparing effects, and anesthesia recovery time.
Pathogenesis, detection, and control of scrapie in sheep
Authors: Cassmann Eric D. , Greenlee Justin J. 
Published: June 2020

Abstract
In sheep, scrapie is a fatal neurologic disease that is caused by a misfolded protein called a prion (designated PrPSc). The normal cellular prion protein (PrPC) is encoded by an endogenous gene, PRNP, that is present in high concentrations within the CNS. Although a broad range of functions has been described for PrPC, its entire range of functions has yet to be fully elucidated. Accumulation of PrPSc results in neurodegeneration. The PRNP gene has several naturally occurring polymorphisms, and there is a strong correlation between scrapie susceptibility and PRNP genotype. The cornerstone of scrapie eradication programs is the selection of scrapie-resistant genotypes to eliminate classical scrapie. Transmission of classical scrapie in sheep occurs during the prenatal and periparturient periods when lambs are highly susceptible. Initially, the scrapie agent is disseminated throughout the lymphoid system and into the CNS. Shedding of the scrapie agent occurs before the onset of clinical signs. In contrast to classical scrapie, atypical scrapie is believed to be a spontaneous disease that occurs in isolated instances in older animals within a flock. The agent that causes atypical scrapie is not considered to be naturally transmissible. Transmission of the scrapie agent to species other than sheep, including deer, has been experimentally demonstrated as has the transmission of nonscrapie prion agents to sheep. The purpose of this review is to outline the current methods for diagnosing scrapie in sheep and the techniques used for studying the pathogenesis and host range of the scrapie agent. Also discussed is the US scrapie eradication program including recent updates.

Coffee grounds residue are the primary waste obtained from brewed coffee. Furthermore, some reports showed that coffee grounds residues still containes of bioactive compounds like caffeine and total phenolic compounds. This study aims 1) to know the effect of ethanol solvent concentration and maceration temperature on extract characteristics of coffee grounds robusta extract, and 2) to determine the concentration of ethanol solvent and best maceration temperature to of coffee grounds robusta extract. This experiment uses Factorial Random Design with two factors. The first factor concentration of ethanol solvent consists of 3 levels: 70%, 80%, 90%. The second factor is the maceration temperature which consists of 3 levels: 45oC, 60oC, 75oC. From the above two factors obtained 9 treatment combinations, each grouped into 2 groups as 18 units of experiments. The result showed that etanol solvent concentration, maceration temperature and interaction between trearments had high significantly effect on yield extract and caffeine content. The ethanol solvent concentration treatment had a significant effect, while the treatment of the maceration temperature and the interaction between trearments had a significantly effect on the total phenol. The treatment of ethanol solvent concentration 90% and maceration temperature 60oC was the best characteristic with robusta coffee extract yield 7.87±0.05% yield, 0.70±0.01% caffeine content and total phenol 11,052.83±1,124.30 mg GAE/100g.
