Adecuaciones para mejorar la aplicación del método D3987-85 en la extracción de EPT de los antiguos residuos mineros El Fraile, Guerrero, México
Authors: Corrales-Pérez Daniel , Martín-Romero Francisco
Published: April 2018

El método D3987-85 es uno de los procedimientos de lixiviación utilizados en el mundo para evaluar la peligrosidad de los jales de minas. El método ha sido oficializado en México en la Norma Oficial Mexicana NOM-141-SEMARNAT-2003; y durante su aplicación se han reportado inconsistencias que podrían traer graves repercusiones en la salud humana y en el ambiente. En el presente estudio se realizaron modificaciones al tiempo de agitación y relación de mezcla indicados en el método D3987-85. Adicionalmente, se implementaron técnicas eficientes de muestreo para representar más acertadamente la peligrosidad de los antiguos residuos depositados en la presa de jales El Fraile, localizada en Taxco, estado de Guerrero, México. Los jales se caracterizan por presentar concentraciones totales (mg/kg) de elementos potencialmente tóxicos (EPT) en los siguientes intervalos: As (1,719.0–3,412.1), Ag (27.8–55.7), Ba (152.1–527.3), Cd (15.6–49.7), Cu (89.7–204.5), Mn (243.6–2,195.5), Pb (3,084.9–4,930.1), Zn (449.0–5,558.7), y la presencia de las siguientes fases minerales, en orden de abundancia: cuarzo, yeso, jarosita potásica, filosilicatos, hematita, feldespatos potásicos tipo sanidina. Así mismo, de las presas de jales se colectaron tres muestras de efluentes ácidos (pH: 2.0–2.6), que registraron concentraciones (mg/L) de SO42- (3,509.3–12,249.9), Fe (459.3–1,505.0) y EPT (As: 0.7–1.3, Cd: 2.8–12.3, Cu: 6.1–23.7, Mn: 76.4–316, Zn: 334.5–1,262.5), y fueron comparadas con la composición química de las suspensiones de jales en agua (SJA) preparadas en laboratorio mediante el método D3987-85. Los efluentes ácidos son clasificados como peligrosos con base en las concentraciones de Cd disuelto (>1.0 mg/L), ya que sobrepasaron el límite máximo permisible regulado en la Norma Oficial Mexicana 141. Sin embargo, cuando se comparó la peligrosidad de las SJA preparadas mediante el método D3987-85 (18 ± 0.25 h y relación sólido-extractante de 1:20), resultó que no son peligrosos, ya que las SJA presentaron concentraciones de Cd disuelto que oscilan entre 0.2 a 0.4 mg/L. No obstante, cuando se realizaron modificaciones al método D3987-85 que consistieron en aumentar los tiempos de agitación (24 ± 0.25 h, 48 ± 0.25 h, 72 ± 0.25 h, 192 ± 0.25 h) y disminuir las relaciones de mezcla (1:10, 1:3), se obtuvieron concentraciones de Cd disuelto que oscilan entre 0.3 a 2.4 mg/L. De esta forma, se logró demostrar que las SJA obtenidas con el método modificado representan mejor la composición geoquímica de los efluentes ácidos colectados en campo, lo cual contribuye a evaluar la peligrosidad de los jales de forma más rigurosa y confiable.
Carboniferous biostratigraphy of Sonora: a review
Authors: Navas-Parejo Pilar
Published: April 2018

A thorough review of the available literature regarding biostratigraphic studies on the Carboniferous sedimentary rocks of Sonora, northwestern Mexico, is presented here. Most frequently reported fossils are marine invertebrates as well as protozoans and vertebrate remains. Most abundant groups are corals, both solitary and colonial, fusulinids and other foraminifera, conodonts, and brachiopods. Less commonly described groups are crinoids, algae, bryozoans, and radiolarians. This revision evidences the high paleobiodiversity and potential research interest of the Carboniferous geological record of Sonora. Although published studies including paleontological information greatly lack detailed specific taxonomic determinations or biostratigraphic analyses, the presence of all Mississippian and Pennsylvanian stages can be inferred. Regional stratigraphic gaps and hiatuses, however, are difficult to determine because of this scarcity of precise datings. Current lithostratigraphic units defined formally or informally are also reviewed.

Authors: Reitz Randall , Horst Kyle , Davenport Maura , Klemmetsen Shiela , Clark Michael
Published: April 2018

Background and Objectives: Despite the efforts of many organizations to increase the volume of rural health care providers, rural communities continue to experience a shortage of physicians. To address this shortage, more information is needed as to how specific factors contribute to family physicians’ choice to purse rural full-spectrum practice.
Methods: Interviews with 21 key informants guided a grounded theory analysis around the question of “What factors contribute to the decision to, and maintenance of, practicing full-spectrum rural medicine?”
Results: Analysis revealed two categories of factors that influenced choice of scope and maintenance of scope across a career: contextual and developmental factors. Contextual factors included the national health care landscape, the local setting, and personal factors. The developmental factors pertained to the point in the physician’s career, and include preprofessional envisioned scope, current scope, and ideal future scope of practice.
Conclusions: Results describe how a rural physician’s scope of practice generally narrows as her/his career progresses. The results elaborate on how the larger health care landscape, local community, and personal factors all intersect to inform a physician’s decision to pursue and/or continue practice. Results of the study were consistent with preexisting literature, but provide additional depth and suggest a theoretical relationship among factors.

Published: April 2018

Background and Objectives: Medical scribes are an increasingly popular strategy for reducing clerical burden, but little is known about their effect on medical student education. We aimed to evaluate the impact of scribes on medical students’ self-reported learning experience.
Methods: We conducted a mixed-methods pilot study. Participants were medical students (third and fourth years) on a family medicine clerkship who worked with an attending physician who practiced with a scribe. Students did not work directly with scribes. Scribes charted for attending physicians during encounters that did not involve a student. Outcomes were three 7-point Likert scale questions about teaching quality and an open-ended written reflection. Qualitative data was analyzed using a constant comparative method and grounded theory approach.
Results: A total of 16 medical students returned at least one questionnaire, yielding 28 completed surveys. Students reported high satisfaction with their learning experience and time spent face-to-face with their attending, and found scribes nondisruptive to their learning. Major themes of the open-ended reflections included more time for teaching and feedback, physicians who were less stressed and more attentive, appreciation for a culture of teamwork, and scribes serving as an electronic health records (EHR) resource.
Conclusions: To our knowledge, this is the first study evaluating the effect of scribes on medical student education from the students’ perspective. Our findings suggest that scribes may allow for greater teaching focus, contribute to a teamwork culture, and serve as an EHR resource. Scribes appear to benefit medical students’ learning experience. Larger and more rigorous studies are needed.

Authors: Szabella Olivér
Published: April 2018

A digitális világ fejlődésének köszönhetően a videojátékok és a professzionalizmus együttes megjelenését figyelhetjük meg. Ezt a jelenséget nevezhetjük e-sportnak. Az ezzel foglalkozó szubkultúra gyökerei visszavezethetőek a ’70-es és ’80-as évekre, azonban maga az e-sport csak a közelmúltban alakult ki. Ennek ellenére hatalmas fejlődésen ment át, manapság már diverzifikált, így a megértéséhez megfelelő tipológia is szükséges. Bonyolult versenyrendszerekkel rendelkezik, nemzetközi szövetség segíti a fejlődését, és komoly kapcsolódási pontokat fedezhetünk fel a hagyományos sportok és az e-sportok tulajdonságai között. Fontos leszögezni azonban, hogy nem minden videojáték e-sport! Ahhoz, hogy mélyebben megértsük ezen iparág működését, meg kell értenünk, honnan fakad a médiaképessége, és azt is, milyen csatornákon éri el a többmilliós érdeklődő réteget. Magyarországon most kezdik felismerni az üzleti jelentőségét és a mögötte álló tömegbázisban rejlő lehetőségeket. Ennek köszönhetően hazánkban is lehetőség nyílhat a digitális sportok gyors ütemű fejlődésére.

Esport as business? The emergence of an industry

Video games and professionalism are appearing together, thanks to the world’s technological advancement. This appearance is called esport. The subculture around it can be traced back to the ‘70s and ‘80s, although esport itself did not appear too long ago. Despite its novelty, the world of digital sports has gone through an enormous advancement since its appearance. Nowadays it is diversificated and needs a self-explanatory typology to be handled well. Connection points can be observed between the world of sports and esports. There are serious competition systems. Professional athletes and a fully functional international organization helps the development of esport. To fully understand the industry and its growth it is necessary to observe the media capability and its distribution channels. Hungary is starting to recognize esports’ business value and the opportunity within its mass support base. Thanks to this digital sports in this country may well also develop more rapidly.

A két kutatás számos témát felölelt, ezek közül a tanulmány először a videojáték kutatás eredményeit ismertetve kitér arra, hogy mennyien játszanak videojátékkal idehaza és ehhez mik a főbb motivációik. Foglalkozik annak vizsgálatával, hogy a nem játszók körében mennyire elterjedtek a videojátékosokkal kapcsolatos negatív sztereotípiák, illetve milyen a szülők viszonya a témához. Ezt követően bemutatja, hogy min és mit játszanak a játékosok, illetve mekkora az e-sport játékkal játszók hazai bázisa. A tanulmány ismerteti az e-sport kutatás eredményeit is, így, hogy mik a főbb játékplatformok, hány órát tesz ki a játékkal töltött idő és az általában vett „screen time”, mi mondható az egyéni fejlődésről és streamek követéséről, valamint, hogy hagyományos értelemben sportolnak-e egyáltalán a gamerek? A tanulmány kísérletet tesz a videojátékokhoz köthető piac magyarországi méretének becslésére is. Végül a befejezésben azt vizsgálja, hogy vajon széleskörű társadalmi elfogadottság előtt áll-e idehaza a videojáték és az e-sport?

Authors: Serrano Nicolás Alejandro
Published: April 2018

En este trabajo se ofrece una respuesta conceptualista a la crítica de circularidad en la adquisición y posesión de conceptos observacionales, esgrimida por Peacocke. Tal respuesta consiste en proponer un proceso de categorización subpersonal que pueda hacer disponibles los conceptos observacionales relevantes con antelación a que el sujeto se encuentre en la experiencia perceptiva correspondiente. Ofrezco sustento empírico a esta respuesta a partir de resultados experimentales en ciencias cognitivas relacionados con la percepción del color. Estos experimentos evidencian influencias lingüístico-conceptuales en el procesamiento temprano de estímulos perceptivos, de un modo que respeta los límites establecidos por las categorías lingüísticas de los hablantes. Por último, y tras responder algunas posibles objeciones, concluyo que hay razones tanto conceptuales como empíricas para defender una respuesta conceptualista a la crítica de circularidad.

Lemuru fish is one of fishery commodity that has high economical value and one of fish that most catched by fisherman in Bali Strait. Lemuru fish had been caught in Bali Strait was fluctuating every month and every years. This condition was related with food source of Lemuru fish such as phytoplankton and zooplankton. So this research was conducted to explained the relationship phytoplankton and zooplankton abundance with Lemuru fish catched  in Bali strait. This study focus in Bali strait during March until May 2017. Determination of sampling point used area sampling method while water sampling occured in surface water with pouring method. Total of phytoplankton and zooplankton abundance in Bali strait in March until May had formed the sinusoidal model with their abundance ranged 301 ind/L – 604 ind/L and 7 ind/L – 12 ind/L. Plankton abundance in Bali strait in March until May (transisonal season 1) was categorized low abundance if compared with plankton abundance in another season. The low value of phytoplankton abundance caused by non upwelling phenomenon and grazing process and the low abundance of zooplankton caused by low rate of zooplankton and predation by Lemuru fish. Phytoplankton and zooplankton abundance had  strong relationship with Lemuru fish catched with correlation coefficient value 0.76 and 0.69. This condition caused by phytoplankton and zooplankton are source of Lemuru fish food.

The ecosystem of mangroves and seagrass in Mertasari Beach are located nearby and and inhabited with various species that coexist, One of the association’s creature in mangrove ecosystem and seagrass ecosystem is crab. There were a habitat selection of crabs, so it does possible to find the same species in the mangrove ecosystem and seagrass ecosystem. This research aims to know the type, abundance and diversity of crabs in the Mertasari Beach on two different ecosystems such as mangrove and seagrass ecosystem. The research were conducted in January until February 2017. In this research the Random sampling method was used to create a 1x1m2 square placed on 5 substations at each research station. Crab sampling was conducted at the lowest tide and has been done twice in a month. The results showed there were 7 families with 20 species. In both ecosystem were found 3 spesies such as Scylla serrata, Grapsus albolineatus and Myomenippe fornasinii. This happens because of several factors, like the tidal and the flow of the river into habitat removal by crabs. The highest abundance of crabs was found in mangrove stations of 411 individuals/m2, while at the seagrass station were 93 individuals/m2 due to food availability and environmental conditions. The highest value diversity index (H) at mangrove station was 1.94 and seagrass station of 1.73 with moderate category indicated in those area had sufficient productivity, conditions of the ecosystem is pretty balanced and moderate ecological pressure.

The status of Indonesian coral reefs are in fair to poor categories, therefore it requires more approaches in order to  recover the natural ecosystem. One of the reef restoration method is coral transplantation. Genus Acropora is one of the main constituent of reefs in the Indo-Pacific waters. Reef transplantation may not only rehabilitate the damaged reef, but also an effective way to collect coral for economic purposes. Acropora secale has high economic value as aquarium ornament, however it is vulnerable to the environmental stress and marine pollution. Therefore, finding the suitable transplantation location is one of important  part in the transplantation. The objective of this research is to investigate the growth of transplant A. Secale at Serangan and Geger Beach which has different morphology feature. A. secale was Transplanted for 3 months on the 2 x 1 m table with 16 fragments and observed each week. The results obtained are total growth and growth rate of A. secale transplanted on Serangan Beach is significant higher than Geger Beach (P<0.05). The total growth of A. secale on Serangan Beach is higher by 0,83 cm, wider by 0,61 cm, and branches are more 7 branches than Geger Beach. The growth rate of A. secale at Serangan Beach was higher by 0,27 cm/month and wider by 0,21 cm/month than Geger Beach. The survival rate of A. secale on Serangan Beach and Geger Beach is 100% which means that all transplanted corals survive until the end of the study.

Tunikata is an animal shaped like a tube and its body is covered by a mantle (tunic). These organisms have functions and impacts for ecology, pharmacology, people and the economy. However, the various important roles of the tunicate are not matched by information on abundance and diversity in Indonesia in general and the island of Bali in particular. Therefore, this study aims to determine the abundance, species composition and the diversity of tunikata in the waters of Jemeluk and Penuktukan, Bali, where each of these waters has a different coral reef morphology reef flats (Jemeluk) and reef slopes (Penuktukan). Data retrieval is done with a 25x2m2 belt transect and parallel to the shoreline. Determination of location of observation based on purposive sampling method. Analysis of the data used using the abundance formula, species composition and the Shannon-Wiener diversity index. The results showed that the abundance of tunikata in Jemeluk waters did not differ significantly between stations where the highest was found in stations 1 and 3, the lowest at station 2. But the abundance of tunicates in waters Penuktukan significantly different between stations where the highest in three and the lowest station on Station 1. There are nine kinds of tunicates on both waters where species Didemnum molle and Atriolum robustum is the type most commonly found. The highest diversity of tunicate species in Jemeluk waters is found in stations 1 and 3 and the lowest is at station 2, while the highest Penuktukan is located at station 1 and the lowest is at station 3. In general, the index of biodiversity in both waters is categorized as low.

Benoa Bay is one of the unique ecosystems on the island of Bali because it is a shallow estuary area and has an ecosystem that is important for the waters of the mangrove ecosystem and seagrass. In recent years, Benoa Bay has been reported to have undergone siltation due to sedimentation. However, there has not been much scientific study of the sedimentation rate occurring in Benoa Bay. The study of sedimentation will provide an overview of the rate of sedimetation in the study area. Numerical modeling is one of the most commonly used methods to describe hydrodynamic processes in waters, which are the main drivers of the process of movement of pollutants in waters such as waste, sediment, and others. Thus, the study of sedimentation rate, either spatially or temporally, needs to be done in the waters of Benoa Bay using numerical modeling. The results of this study show that sedimentation rates in Benoa Bay have a minimum value of 1.08x10-6 and a maximum of 24.88 kg/m2/day with an average of 0.57 kg/m2/day. High sedimentation rates occur in the western part of the bay, on the river route, and in the northern part of the bay, between Serangan Island and Mertasari beach. Areas that potentially experience silting in Benoa Bay include the southern port of Benoa Harbor which reaches 0.23 m/year, the waters north of Serangan Island reaching 0.008 m/year, and the area close to the estuary which reaches 0.35 m/year.

Mashavu (“chubby-cheeked” in Swahili) is a telemedicine system that connects medical professionals around the world with people in developing communities in East Africa. Mashavu kiosks are computer-based systems that collect medical information including weight, body temperature, lung capacity, pulse rate, blood pressure, stethoscope rhythms, photographs and basic hygiene and nutrition information. Mashavu kiosks transmit this information over a cell-phone link to a secure Internet website. Medical professionals and public health officials can view the patient’s information and respond to the person/operator and the nearest doctor(s) with recommendations. An imperative part of complex product design, especially when working in international contexts, is to gain validation. Validation ensures that the product being designed accurately fits the needs of the population for which it is being designed. The Mashavu team used methodologies from the world of engineering, business, and the social sciences to validate the concept, business plan, technology and usability of the system. This paper discusses the Mashavu venture and the methodologies employed for getting validation and uncovering the "sticky" information related to the East African context that is critical to the design and commercialization of the Mashavu telemedicine system.

Published: April 2018

The pressure-temperature phase diagram of the dimorphism of racemic m-nisoldipine is constructed using temperatures and enthalpies of fusion of forms A and B. At ordinary pressure, the transition from form B to form A is found to occur around 192 K, which indicates that these polymorphs are enantiotropically related and that form A is stable at room temperature. Nevertheless, the phase relationship turns to be monotropic when pressures become greater than about 100 MPa, which indicates that form B becomes the sole stable phase.
