Published: April 2019

Se presenta la evaluación del procedimiento de extracción secuencial aprobado por la BCR (BCR, por sus siglas en inglés, Community Bureau of Reference) para determinar metales en muestras de sedimentos del río Catatumbo, Venezuela. Las fracciones consistieron en 4 etapas: en la primera, llamada intercambiable, se extrajo utilizando ácido acético; la segunda, o reducible, con hidroxicloruro de amonio; la tercera, u oxidable, con peróxido de hidrógeno y acetato de amonio y la residual, que es la etapa remanente, se digirió con agua regia. El análisis se realizó por espectrometría de absorción atómica con llama (FAAS), horno de grafito (ETAAS) y espectrometría de emisión atómica con plasma inductivamente acoplado (ICP-AES). Los metales determinados fueron Pb y V. Las determinaciones por FAAS, ETAAS e ICP-AES indicaron que no hubo diferencias estadísticamente significativas (p < 0,05) cuando se compararon los resultados de 24 muestras de sedimentos del río Catatumbo realizadas por triplicado. La exactitud encontrada sumando las cuatro etapas de la BCR para Pb y V fueron comparables a los resultados obtenidos por digestión ácida, lo cual indica que el procedimiento es adecuado para la cuantificación de los metales estudiados. El Pb y V se encontró mayormente (55-97 %) en la etapa residual lo que los hace no disponibles.

Abstract:

The aim of the present work is the evaluation of the procedure of sequential extraction approved by the BCR and used to determine metals in samples of sediments from Catatumbo River in Venezuela. The fractions consisted in four (4) stages: the first one or interchangeable was extracted using acetic acid, the second one or reducible with ammonia hydroxi-chloride, the third one or oxidable with hydrogen peroxide and ammonium acetate and the residual which is the remnant stage was digested with aqua regia. The analysis was made by Flame Atomic Absorption Spectrometry (FAAS), Electrothermal Atomisation Atomic Absorption Spectrometry (ETA-AAS) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The metals evaluated were Pb and V. The evaluations for FAAS, ETA-AS and ICP-AES indicated that there were not statistically significant differences (p <0.05) when the results of 24 samples of sediments from the Catatumbo River carried out in triplicate were compared. The exact result found by adding the four stages of the BCR for Pb and V were comparable to the results obtained by acid digestion. The Pb and V were found mainly (55-97 %) in the residual stage which makes them not available and these results are comparable to other studies published.

Authors: Cano Yulixis , Morales José , Sosa de Borrego Beatriz , Sánchez Ligbel , Velásquez Harvi , Torres Julio , Montilla Brinolfo
Published: April 2019

En este trabajo se evaluaron las concentraciones de los iones solubles en agua en las partículas inhalables (PM10) usando cromatografía iónica. Para el análisis de Cl-, NO3-, SO42-, PO43-, Na+, K+, Ca2+ y Mg2+ en partículas inhalables colectadas en la ciudad de Maracaibo (Venezuela) se utilizó la técnica de cromatografía iónica (CI) con un sistema con un sistema DIONEX modelo 2000i/sp. El análisis por CI fue comparado con los valores obtenidos por la técnica de ICP-OES. Los resultados por CI están muy cercanos a los obtenidos por ICP-OES y es una excelente alternativa confiable y exacta para el análisis de cationes en partículas atmosféricas. Los altos niveles de sulfato, nitrato y cloruro encontrados podrían estar relacionados con importantes emisiones de la industria petrolera, petroquímica; y el tráfico automotor en la atmósfera de la ciudad. Al comparar las concentraciones de los iones evaluados en este estudio con las zonas rurales de Venezuela y el mundo revelo que estos son alrededor de 10 veces más altos. Las concentraciones de los iones evaluados en Maracaibo fueron similares a los reportados en La Concepción (Venezuela) y Heredia (Costa Rica). Sin embargo, los valores reportados para ciudades como Ahváz (Irán), Shanghai (China) y Haungshi (China), son aproximadamente de 2 a 10 veces mayores que en este estudio.

Palabras clave: PM10, partículas atmosféricas, aniones y cationes.

ABSTRACT:

In this work concentrations of water soluble ions in inhalable particles (PM10) were evaluated using ion chromatography. For the analysis of Cl-, NO3-, SO42-, PO43- and Na+, K+, Ca2+, Mg2+ in inhalable particles collected in Maracaibo (Venezuela) the ion chromatography (IC) technique was used with a DIONEX model 2000i / sp system. The analysis by IC of metallic cations was compared with the values obtained by ICP-OES techniques. The results by IC closely agreed with those obtained by ICP–OES and this excellent alternative technique enabled accurate and reliable analysis of cations in atmospheric particles. The high levels of sulfate, nitrate and chloride found could be related to important emissions from the petroleum, petrochemical industry; and automotive traffic in the atmosphere of the city.  Comparing the concentrations of ions evaluated in this study with rural areas of Venezuela and the world revealed that these are about 10 times higher. The concentrations of ions evaluated in Maracaibo were similar to those reported in La Concepción (Venezuela) and Heredia (Costa Rica). However, reported values for cities like Ahváz (Iran), Shanghai (China) and Haungshi (China), are approximately 2 to 10 times higher than in this study.

Authors: Contreras Jesús , Juárez Jessica , Jaimez Juan
Published: April 2019

Hidrogeles de poliacrilamida (PAAm) y de poli(acrilamida-co-ácido itacónico) (P(AAm-co-AI)) sintetizados en agua y en una solución acuosa de buffer de fosfato al 0,2 M, fueron usados como soporte en los medios de cultivo de tejido vegetal sistema autotrófico hidropónico (SAH) y cultivo in-vitro con solución nutritiva Murashige-Skoog (MS) para la producción de plántulas de papa (Solanum Tuberosum, L). En los bioensayos realizados fue evaluado el comportamiento de los hidrogeles mediante el análisis de las características morfológicas de las plántulas: longitud de la parte aérea, longitud de la raíz, número de entrenudos y biomasa. Estos parámetros fueron analizados aplicando el análisis de varianza ANOVA de dos factores con múltiples muestras, en donde los factores evaluados fueron el tipo de hidrogel y el solvente usado para su síntesis. Los resultados obtenidos muestran que según el medio de cultivo estas variables se ven favorecidas por el uso de un determinado tipo de hidrogel, es decir, en el SAH los hidrogeles de PAAm son los que presentaron mejores resultados desde el punto de vista morfológico y estadístico. Para el cultivo in-vitro con solución nutritiva MS, las propiedades morfológicas de las plántulas, se vieron beneficiadas por el hidrogel de P(AAm-co-AI) sintetizado en la solución acuosa de buffer de fosfato.

ABSTRACT

Hydrogels from poly (acrylamide) (PAAm) and of poly (acrylamide-co-itaconic acid) (P (AAm-co-AI)) synthesized in water and in an aqueous solution of phosphate buffer 0.2 M, were used as a support in the vegetable tissue culture media hydroponic autotrophic system (HAS) and in-vitro culture with Murashige-Skoog (MS) nutrient solution for the production of potato seedlings (Solanum Tuberosum, L). In the bioassays carried out, the behavior of the hydrogels was evaluated by analyzing the morphological characteristics of the seedlings: length of the aerial part, length of the root, number of internodes and biomass. These parameters were analyzed by applying the ANOVA variance analysis of two factors with multiple samples, in which the factors evaluated were the type of hydrogel and the solvent used for its synthesis. The results obtained show that, according to the culture medium, these variables are favored by the use of a certain type of hydrogel, which, in the SAH the PAAm hydrogels are the ones that presented the best results from the morphological and statistical point of view. For the in-vitro culture with MS nutrient solution, the morphological properties of the seedlings were advantageous due to the P(AAm-co-AI) hydrogel synthesized in the aqueous solution of phosphate buffer.

Abstract

 

Different investigations on the Boraginaceae family have focused on the search for substances of proven pharmacological activity. The Cordia sebestena species, has not been studied as much, in a chemical and pharmacological way, so it is interesting to study this endemic plant in the western Venezuelan region. The plant material was collected in the city of Maracaibo, Zulia state. Raw hydroalcoholic extract was obtained from the fresh leaves by maceration with isopropanol-water (7: 3). By means of acid-base extraction, the fraction of strong acids was obtained. It was separated by column chromatography to obtain Af-1 subfraction, from which a yellow solid was isolated with mp 170 ° C, which was characterized chemically and spectroscopically by UV, IR and 1H, 13C NMR and identified as rosmarinic acid. Rosmarinic acid is an ester of caffeic acid and 3,4-dihydroxyphenyl lactic acid, a natural phenyl propanoid, which is found mainly in the species of the family Boraginaceae, the subfamily Nepetoideae of the family Lameaceae and in some lower plants such as Ferns.

The surgical procedure of syringomyelie with Chiari I in adults regarding the intrapial aspiration of cerebellar tonsils: does this procedure improve symptoms with less complication?
Authors: Mustapha Ait Bachir , Benbouzid T.
Published: April 2019

Introduction. Cranio-vertebral decompression remains the common denominator for the treatment of syringomyelia associated with Chiari I. On the other hand, the details of the procedure, remains controversial. The success of the surgery is to restore the circulation of cerebro-spinal fluid at the level of the foramen magnum. How is this circulation restored to the level of foramen is the question? We offer our attitude towards the treatment of syringomyelia with Chiari I.

Material and method. Consecutive series of 32/121 patients benefiting from cranio-vertebral decompression associated with intrapial aspiration of cerebellar tonsils treated for syringomyelia with a Chiari I malformation in adults.

Result. Motor deficits were present in 20 / 22 patients, representing 90% of the entire patient group. these motor deficits are improved in 16 out of 22 cases, and remained unchanged in 06cas. no motor aggravation occurred. in our study, bone decompression and intra pial aspiration of cerebellar tonsils (sub arachnoids manipulation) were found to be associated with favourable results on clinical signs and symptoms. However, sub arachnoids manipulation and intra pial aspiration of cerebellar tonsils showed a little more complication compared with bone decompression with dural plasty.

Conclusion. The bone decompression with dural graft and intradural dissection of adhesions and reduction by intra pial aspiration or resection of the tonsils is indicated on the MRI aspect of cerebellar tonsils of considerable size totally obstructing the foramen Magnum, the intraoperative finding, through the arachnoid, of the absence of passage of the cerebro-spinal fluid because of the bulging of the cerebellar tonsils.

Antibiotic Resistance in the Veterinary Perspective
Authors: Inbaraj Sophia , Sriram Vamshi Krishna , Thomas Prasad , Verma Abhishek , Chaudhuri Pallab
Published: April 2019

Antibiotic resistance is an emerging threat to achieving one health all over the globe. The phenomenon leads to the emergence of drug-resistant microbes previously susceptible to an antibiotic. Drug-resistant microbes are the major reasons for medical complications like patient mortality and treatment failure. Unregulated use of antibiotics in animal husbandry is one of the major reasons for the emergence of antibiotic resistance. The resistance enters the human population mainly through the food chain. The genetic markers associated with drug resistance spread among different bacterial species by horizontal gene transfer mechanisms. Therefore, regulation of antibiotics use in animal husbandry and proper safety measures at farm level are necessary to check drug-resistant microbes entering the food chain. This chapter discusses the antibiotics, antibiotic resistance, genetic mechanisms involved, the spread of resistance, and also the available strategies to combat antimicrobial drug resistance.

Communities of Practice
Authors: McGaw Martha Ann Davis
Published: April 2019

Despite continued efforts of educational professionals to develop a quality, meaningful classroom experience for teachers and students, relevant to employability, there still exists in the USA a skills gap. This gap has created a lack of a competitive advantage in the national and global marketplace as well as a low return on investment. There is a growing consensus that highly developed education systems are unlikely to be capable of the kind of change which is urgently needed. Community-building in education is not just about creating or defining a new work for teachers to do collaboratively. It is about changing a school's professional culture. Establishing communities of practice (CoP) involves the whole educational experience. Engaging with learning has become a central focus for educators, administrators, business, and community leaders. This chapter attempts to bridge the gap between the either-ors by presenting a learning ecosystem and three case studies highlighting successful CoPs.
Pedagogic Frailty and the Ecology of Teaching at University
Authors: Kinchin Ian M.
Published: April 2019

The effective consideration of university teaching through an ecological lens requires a supporting framework that is able to add a sense of coherence to an evolving and seemingly chaotic professional environment. This can be provided through application of the pedagogic frailty model that supports the visualization of key aspects of the teaching environment. This is achieved using concept mapping as a tool to uncover the personalized ways in which academics make connections between ideas. This chapter considers examples to show how through the application of concept mapping exploration the model can add to the comprehensibility, manageability, and meaningfulness of the teaching enterprise so that individual academics may be better placed to map their own career aspirations and institutional managers may gain a more informative and integrated picture of the dynamic university system.

Entrepreneurial Leadership as a Driver of Innovation Success in Family SMEs in Colombia
Authors: Arzubiaga Unai , Álamo Pablo
Published: April 2019

This chapter aims to analyze if entrepreneurial leadership, regarded as a distinctive feature of entrepreneurial processes, represents an essential element for obtaining satisfactory innovation performance in an emerging context such as Colombia in Latin America. The relationship between entrepreneurial leadership and innovation management works differently in family firms (FF) compared with their non-family counterparts. Indeed, there is no consensus in the literature on the effects of entrepreneurial leadership on innovation success in family small and medium-sized enterprises (SMEs). Exploratory research has been conducted considering a survey held on family SMEs in Colombia. Results highlight the importance of supporting entrepreneurial leadership in order to achieve the innovation goals in these types of organizations and show how these factors change between family SMEs with family CEOs and non-family CEOs. In this sense, although the focus in this chapter is on FF, the conclusions could be to some extent generalized to SMEs.

Authors: Alan Alev Kocak , Kabadayi Ebru Tumer , Bakis Selen
Published: April 2019

This chapter explores behavioral intention of consumers of online music services through analyzing the relationship between experiential motives (enjoyment, escape, epistemic curiosity, and social affiliation) of consumers and their trust in these service providers. Besides, the moderating role of personal characteristics namely personal innovativeness and individual mobility on the trust and behavioral intention relationship is analyzed. Theoretical model and seven hypotheses were proposed and structural equation modelling (SEM) was used to test these hypotheses. Data were collected via online survey and 404 usable surveys were gathered. The results suggest that all experiential motives have a positive effect on trust in the service provider and trust has a positive effect on the behavioral intention of online music service users. Interaction effects of trust and personal innovativeness and trust and individual mobility on the adoption of these services were also justified.

Transcending the Challenge at the Library
Authors: Dávila Denise , Xu Yunying
Published: April 2019

One of the greatest challenges immigrant families face in local communities is the harmful quality of mainstream deficit perspectives about immigration. This chapter focuses on a group of Latinx immigrant families' first experiences with local public libraries' education services within the New Latino Diaspora of the U.S. Southeast, which has been the migratory destination of many immigrant families in the last two decades. It discusses a study that interrogates the efficacy of two acclaimed literacy development programs, Every Child Ready to Read and Prime Time Preschool. These programs were facilitated by public libraries in the state of Georgia and attended by Latinx immigrant families with young children. The study findings illustrate how the families' engagement in the programs disrupted injurious social narratives that privilege whiteness and inhibit the recognition of Latinx immigrants as members of local U.S. communities and mainstream American society.

Published: April 2019

The Millennial generation (Gen Y) will comprise half of the global workforce by 2020 and three-fourths of the workforce by 2025. With limited career and growth opportunities in many sectors, many higher education aspirants are looking to reskill themselves in the field of management. The challenge is that this generation has a very different value orientation than that of the previous generation (Gen X). Therefore, understanding the learning attitudes and attributes of this generation could provide useful insights into the strategies that might be effective in the admission selection process. This chapter surveyed 560 students recently admitted to the management institute in and around Delhi region to assess their learning motivations. The results show that the students were very confident in their ability to participate and perform well in the course. They were attracted to the teaching methodologies and networking opportunities. The close interaction between the students, peers, and faculty was one of the main sources of motivation for them to join the institute.

To describe the epidemiology of injuries sustained in high school boys' baseball in the 2005–2006 through 2013–2014 academic years and collegiate men's baseball in the 2004–2005 through 2013–2014 academic years using Web-based sports injury surveillance.

Design

Descriptive epidemiology study.

Setting

Online injury surveillance from baseball teams in high school boys (annual average = 100) and collegiate men (annual average = 34).

Patients or Other Participants

Boys' or men's baseball players who participated in practices and competitions during the 2005–2006 through 2013–2014 academic years in high school or the 2004–2005 through 2013–2014 academic years in college, respectively.

Main Outcome Measure(s)

Athletic trainers collected time-loss injury and exposure data. Injury rates per 1000 athlete-exposures (AEs) were calculated. Injury rate ratios (IRRs) with 95% confidence intervals (CIs) compared injury rates by school size or division, time in season, event type, and competition level.

Results

The High School Reporting Information Online system documented 1537 time-loss injuries during 1 573 257 AEs; the National Collegiate Athletic Association Injury Surveillance Program documented 2574 time-loss injuries during 804 737 AEs. The injury rate was higher in college than in high school (3.20 versus 0.98/1000 AEs; IRR = 3.27; 95% CI = 3.07, 3.49). The competition injury rate was higher than the practice injury rate in high school (IRR = 2.27; 95% CI = 2.05, 2.51) and college (IRR = 2.32; 95% CI = 2.15, 2.51). Baseball players at the high school and collegiate levels sustained a variety of injuries across the body, with the most common injuries reported to the upper extremity. Many injuries also occurred while fielding or pitching.

Conclusions

Injury rates were greater in collegiate versus high school baseball and in competition versus practice. These findings highlight the need for injury-prevention interventions focused on reducing the incidence of upper extremity injuries and protecting batters from pitches and fielders from batted balls.

Health care providers are encouraged to provide care according to practice recommendations because these suggestions should improve patient care and promote optimal patient outcomes. The goals of these practice recommendations are to improve patient care and promote optimal patient outcomes. However, without integration into clinical practice, the value of practice recommendations in supporting patient care is lost. Unfortunately, little is known about the success of integrating practice recommendations into clinical practice, and targeted efforts to promote integration are likely needed. Implementation research is a broad area of study that focuses on how guidelines, programs, or interventions are put into practice and delivered. The Translating Research Into Injury Prevention Practice (TRIPP) framework consists of 6 stages that support implementation science, and the framework has been used to assist in integrating injury-prevention programs into patient care. The structure of the TRIPP framework makes it applicable to other programs that would benefit from implementation science, including practice recommendations. Stages 5 and 6 of the TRIPP framework emphasize the need to explore the implementation context and factors related to uptake of a program by end users. This commentary highlights our efforts to use methods for implementation research to evaluate stage 5 of the TRIPP framework as it relates to acute care for patients with suspected spine injuries and provides 6 lessons learned that may assist in future efforts to better implement practice recommendations in patient care. Targeted efforts to assist clinicians in implementing practice recommendations may promote their use and ultimately enhance the care provided for patients with a variety of health conditions. An essential component of any implementation effort is understanding end users via stages 5 and 6 of the TRIPP framework, and this understanding may maximize knowledge translation and encourage practice change and advancement.
Results of observations made with the reversible meridian circle, 1950-1953, catalogue of 812 stars, corrections to 347 FK3 stars

Published: April 2019

This publication contains the results of observations made with the Ottawa Meridian Circle from July 1950 to December 1953. The observing program comprised 639 stars required for the photographie zenith telescopes at Ottawa, Herstmonceux, England, and Richmond,
Florida, U.S.A., and 173 additional stars; 72 from the Pleiades and Perseus groupa and 101 B type stars from a list suggested by Dr. J. H. Oort. The final positions were obtaiued differentially from observations taken at the same time on 347 FK3 stars considered as fundamentals. The internai
probable error of the places is under 't20; the attachment to FK3 is shown. New proper motions are given for the stars of the Ottawa zenith list.
Tables of extended distances for PPP, pPP, pPKP and for P at very short distances
Authors: Hodgson J H , Allen J F J , Cock J I
Published: April 2019

The paper presents tables of extended distances for several secondary phases which are occasionally useful in fault-plane solutions, and extends earlier tables for P to very short distances. The tables are given for surface focus and for focal depths ranging from
O·00R to O·12R in steps of O·01R. They are consistent with earlier tables of extended distances so that the several phases can be used in a single solution.
Direction of faulting in some of the larger earthquakes of the north Pacific, 1950-1953
Authors: Hodgson J H
Published: April 2019

The direction of faulting is determined for 11 earthquakes occurring in the north Pacific during the years 1950-1953. One of these is the great Kamchatka earthquake of November 4, 1952. It is shown that this earthquake was probably a double one; solutions a re
presented for each of the postulated shocks.
Combining the present solutions with those published earlier provides 24 solutions for consideration. These indicate that in Alaska, British Columbia and Washington faulting may be normal, thrust or transcurrent with no pattern yet apparent in the direction of strike or dip or the planes. In other
areas or the north Pacific transcurrent faulting on steeply dipping planes seems to be the rule. The strike direction of the planes seems to be random, but the dip vector and the null vectors appear to lie parallel to nearly vertical planes. These planes probably have some tectonic significance,
although so far it has not been possible to establish its exact character.
A seismic investigation of mine 'bumps' in the Crowsnest Pass coal field
Authors: Milne W G , White R H
Published: April 2019

ln September, 1953, seismographs were installed in the Crowsnest Pass area of Alberta and British Columbia to study the 'bumps'. which were occurring in the coal mmes at Fernie and Coleman, and to investigate the possibility that they might ,be related to minor
earthquakes in the area. During the initial phase of the work, three seismographs were operated at widely separated stations, two in the region of coal mines at Coal Creek and Coleman and one at Turner Valley, distant from any mining operations. Sorne earthquakes were recorded at all three stations
and, in addition, many small disturbances were recorded by the seismographs located near the mines, especially by the instrument at Coal C'reek. A closer network of radiolinked seismographs was then installed near Fernie, the records of which definitely established that the small disturbances were
occurring in the mine workings, both active and inactive. No relationship was established between bumps and local earthquakes in the area. This work was initiated as a cocperative effort with the Fuels Division of the Mines Branch, Department of Mines and Technical Surveys, which has undertaken a
study into the phenornena of ground stress relief in underground mine workings.
Mechanisms of faulting
Authors: Dix C H
Published: April 2019

The faulting picture shown by E. M. Anderson in his book using C. E. Inglis' stress calculations is examined, and it appears difficult to extract energy for radiation in seismic waves from such a picture. Before and after the formation of such a crack the stress
energy appears to be approximately the same.
However if there are two pre-existing 'lubricated' approximately co-planar sheet regions or sheet regions weaker than their surrounding rocks with a strong solid region between them, then this s:ilid between may be ruptured and energy radiated. This may be modified to include the growth of a simple
single lubricated crack but this later process does not seem adequate for large earthquakes.
