Introducción: el análisis de conglomerados de clases latentes (ACCL) es un procedimiento estadístico para agrupamientos, dependiendo de la respuesta a cada ítem. Se ha usado con el trastorno de atención hiperactividad (TDAH), para derivar tipos sutiles de casos en estudios genéticos.
Objetivo: analizar los CCL de 408 miembros de 120 familias con un caso índice de TDAH, en relación con los síntomas registrados en la entrevista psiquiátrica.
Pacientes y métodos: a partir de un caso índice (niño escolarizado de Barranquilla con diagnóstico estándar de oro de TDAH) se construyeron familias nucleares, las cuales de evaluaron para el diagnóstico de TDAH y comorbilidades. La muestra fue de 408 miembros de 120 familias, edad 26,6 ± 15,4 años. Con el programa para computador Latent-Gold 4,0 se hizo el ACCL con la respuesta nominal para cada síntoma de TDAH, y la presencia o no de comorbilidades con TOD y TDC. Se usó el sexo y la edad como covariables categóricas. Se hizo un análisis cruzado de cada conglomerado con el diagnóstico estándar de oro.
Resultados: el mejor modelo (índices de verosimilitud) fue de 6 CCL (p Bootstrap = 0,08). El conglomerado 1 (32,5 %) son adultos, predominio de sexo femenino, probabilidad < 20 % de síntomas y comorbilidades. El segundo (17,4 %) son adultos y niños de sexo masculino con 40 a 80 % de síntomas de TDAH combinado. El grupo tres (15,7 %) son niños con ~100 % síntomas de TDAH combinado, TOD y TDC. El cuarto conglomerado (14,3 %) son adultos de ambos sexos con 20 a 50 % probabilidades de hiperactividad-impulsividad, TOD (70 %) y TDC (40 %). El grupo 5 (10,6 %) en un 80 % adultos con 30 a 90 % probabilidades de inatención sin comorbilidades. El conglomerado 6 (9,5 %) con altas probabilidades de síntomas de inatención.
Conclusiones: se derivaron 6 CCL. Cuatro conglomerados son de afectados, 1 de no afectados y 1 con similar proporción de afectados y no afectados, los cuales podrían ser usados en análisis con marcadores genéticos de susceptibilidad para TDAH.

Abstract
Background: Nonpathogenic Bacillus strains are used in biotechnology, and pathogenic Bacillus strains are cause of food borne disease. It explains the relevance of the methods of detection and quantification of whole cell and cell components of these bacteria. Aims: Development of methodological approach for investigation of dynamics of specific concentration of cell wall antigens per cell of bacilli without solubilization of cell wall during sample preparation; using of the approach with 6 strains of bacilli as an example. Method: ELISA. Results: Methodological approach for investigation of dynamics of specific concentration of bacilli cell wall antigens has been developed. The distinctive features of the approach are rabbit polyclonal antibodies to genera-specific antigens of bacilli as key reagent and lack of need for solubilization of cell wall during sample preparation. It was shown using 6 strains of Bacilli as an example that specific concentration of cell wall antigens per cell vary according to bacillus strain, stage of culture growth and media composition. The data will find an application in biotechnology of clinical diagnostics and test-systems for food control including detection of whole bacillus cells.

Abstract
Control of plant bacterial diseases remains difficult due to the limited availability of efficient plant protection products with reduced negative effects either in the environment or with human and animal health. In order to reduce the usage of chemical pesticides alternative strategies for controlling plant pathogens and improve plant disease resistance are promoted. The aim of the study was to investigate the antibacterial activity of some natural compounds (plant extracts of Tamarix ramosissima, Rosmarinus officinalis, Chelidonium majus, Silybum marianum, Satureja hortensis essential oil and propolis) against bacterial ring rot pathogen, Clavibacter michiganensis ssp. sepedonicus (Cms). An agar diffusion method was used for the screening of the inhibitory effect of natural compounds on bacterial strains’ growth. Minimum inhibition concentrations (MICs) were determined by a twofold serial dilution method. The anti-pathogenic activity was investigated by the study of anti-biofilm activity of natural substances. The analyzed natural substances showed a good microbicidal activity and anti-biofilm activity. The results obtained from this study may contribute to the development of new bio-control agents as alternative strategies for prevention and control of ring rot pathogen.

Authors: Rivera Lassén Ana Irma , Borzone Manuela , Ponomareff Alexander 
Published: March 2017

Abstract
Since the beginnings of 1970s activism in Puerto Rico, like in other countries, there have been tensions between dialogues about race and feminism. Tensions between feminisms and Afrodescendant women's movements persist. As part of a cross-sectional analysis, it is necessary to recognize the wide range of subject positions that combine to create the identities of Afrodescendant women.
Spinning their way into history: Silkworms, mulberries and manufacturing landscapes in China
Authors: Russell Edmund 
Published: March 2017

Abstract
This paper uses the history of silk manufacturing in China as a case study of the impact of biological processes on manufacturing landscapes. The thesis is that the Chinese silk industry succeeded because people inserted themselves as partners in the coevolution of silkworms and mulberry trees. Becoming a coevolutionary partner enabled people to make silkworms and mulberries into more efficient biotechnologies. Silkworms and mulberry trees evolved traits that benefited themselves. People capitalised on those traits, and intensified their expression, through domestic relationships. People pushed evolution of silkworms and mulberries in new directions to maximise their economic value. Coevolution of people, silkworms, and mulberries enabled people to create complex societies marked by gender divisions and social hierarchies.
Breeding uniformity and banking diversity: The genescapes of industrial agriculture, 1935-1970
Authors: Curry Helen Anne 
Published: March 2017

Abstract
In the mid-twentieth century, American agriculturists began to fret about a growing threat to key economic crops: the loss or extinction of manifold local varieties, or landraces, resulting from the displacement of these in cultivation by recently introduced varieties that were better suited for industrial-style agriculture. Many breeders considered diverse landraces to be a valuable, and indeed essential, source of genetic material for their crop improvement efforts - and therefore an essential resource for the very system of agricultural production that appeared to threaten their continued existence. This paper explores how knowledge of this dilemma - that is, the reliance of industrial agriculture on genetic diversity that it tends to destroy - shaped efforts to conserve biological diversity and simultaneously shaped the landscapes and genescapes of twentieth-century agriculture. It takes maize (corn) as its central example, as it was changes in the landscapes of maize production, first in the United States and then across Latin America, which spurred an early international collaboration for the preservation of crop genetic diversity. As it shows with reference to this program and subsequent international developments in the conservation of crop diversity, the technology of the 'seed bank' was considered a crucial addition to the technologies of industrial agricultural production. It was understood to allow breeders to continue responsibly in the creation of high-yielding but ecologically vulnerable inbred crops by lessening the perceived risks inherent in the un-diverse landscapes of industrial monocrop agriculture.
Insecticides, agriculture, and the Anthropocene
Authors: Davis Frederick Rowe 
Published: March 2017

Abstract
Over the course of the past century, agricultural chemists have developed insecticides from plants with phytotoxic properties ('botanical' insecticides) and a range of chemicals including heavy metals such as lead and arsenic, chlorinated hydrocarbons like DDT, and organophosphates like parathion. All of the synthetic insecticides carried profound unintended consequences for ecosystems and wildlife alike. In the process of knowledge and technology transfer of the Green Revolution, industrial agriculture as practiced in the US spread to Mexico, China and India, and around the globe. In the constant search for novel insecticides, chemists returned to nature and developed chemical analogues of the botanical insecticides, first with the synthetic pyrethroids and now with the neonicotinoids. Despite recent introduction, neonics have become widely used in agriculture and there are suspicions that these chemicals contribute to declines in bees and grassland birds. The past and present of pesticides use resonates with themes of the Anthropocene and in particular the Great Acceleration following World War II. Along with chemical fertilisers, pesticides contribute to the conversion of natural ecosystems into human-dominated landscapes.
Industrial ecology and groundwater contamination
Authors: Colten Craig E. 
Published: March 2017

Abstract
This paper reviews the contemporary legal, hydrological, engineering, waste management and water supply literature to illustrate the prevailing knowledge about the environmental processes that operated in waste disposal settings. Framed as a question of past ecological knowledge, it traces the emergence of business managers' conceptualisation of their place in the industrial ecosystem. It also examines the institutionalisation of groundwater pollution by numerous professional groups to illustrate the processes of internalisation. Finally, it offers a historically supported account of the context within which those decision makers' operated. Tracing this process historically offers critical insights into problems and management procedures that might assist with managing wastes associated with the globalisation of industry in new areas.
The value of citizen science: The controversy over municipal solid waste incineration and dioxin pollution in contemporary China
Authors: Da Mao 
Published: March 2017

Abstract
Municipal solid waste incineration (MSWI) has become the subject of one of the most heated environmental debates in mainland China. While government officials and industry representatives are in favour of this technology, claiming that incineration is the most advanced and effective way of managing waste and that the risks are minimal, residents in the vicinity of incinerators are concerned about toxic pollutants, particularly dioxins. This article traces the rise of the anti-incineration movement in China since 2006. It shows how citizens have mobilised, gathered evidence, and informed themselves with the help of internet bulletin board systems; joining forces with NGOs and independent scientific experts, they have petitioned the government and called on government representatives to respond to their concerns in public debates. Dioxin pollution from MSWI continues to be a problem, but the controversy has demonstrated the resourcefulness and determination of Chinese citizens in making their voices heard.

Published: March 2017

Objective: Analise feelings of women accompanying children in a paediatric intensive care unit
Materials and Methods: Data were collected from August to October 2015 by the authors from individual interviews recorded with 15 women. The instrument was structured with the identification of qualitative variables, described in absolute and relative frequencies, and a guiding question. The "corpus" of each interview was electronically transcribed, floating readings were held and statements were categorized and analysed according Analise Content.
Results: 14 (93%) are biological mothers; average age 30 years; 11 (73%) have completed primary education; six (46%) have an occupation or a profession. The four themes were inferred: ambivalence of feelings and coping were related to how individuals express and deal with the hospitalized patient’s situation; empathy with the health team and the structural condition of the critical environment can also generate feelings. Nursing diagnoses were formulated from the reported feelings.
Conclusion: It was observed that the feelings identified could be originated by the health-illness hospitalization process as well as the structural components of the critical environment.

The Bimodal Color Distribution of Small Kuiper Belt Objects*
Authors: Wong Ian , Brown Michael E. 
Published: March 2017

Abstract
We conducted a two-night photometric survey of small Kuiper Belt objects (KBOs) near opposition using the wide-field Hyper Suprime-Cam instrument on the 8.2 m Subaru Telescope. The survey covered about 90 deg2 of sky, with each field imaged in the g and i bands. We detected 356 KBOs, ranging in absolute magnitude from 6.5 to 10.4. Filtering for high-inclination objects within the hot KBO population, we show that the g − i color distribution is strongly bimodal, indicative of two color classes—the red and very red subpopulations. After categorizing objects into the two subpopulations by color, we present the first dedicated analysis of the magnitude distributions of the individual color subpopulations and demonstrate that the two distributions are roughly identical in shape throughout the entire size range covered by our survey. Comparing the color distribution of small hot KBOs with that of Centaurs, we find that they have similar bimodal shapes, thereby providing strong confirmation of previous explanations for the attested bimodality of Centaurs. We also show that the magnitude distributions of the two KBO color subpopulations and the two color subpopulations observed in the Jupiter Trojans are statistically indistinguishable. Finally, we discuss a hypothesis describing the origin of the KBO color bimodality based on our survey results.

Abstract
Three different types of rocks were tested in a high enthalpy air plasma flow. Two terrestrial rocks, basalt and argillite, and an ordinary chondrite, with a 10 mm diameter cylindrical shape were tested in order to observe decomposition, potential fragmentation, and spectral signature. The goal was to simulate meteoroid ablation to interpret meteor observation and compare these observations with ground based measurements. The test flow with a local mass-specific enthalpy of 70 MJ kg−1 results in a surface heat flux at the meteorite fragment surface of approximately 16 MW m−2. The stagnation pressure is 24 hPa, which corresponds to a flight condition in the upper atmosphere around 80 km assuming an entry velocity of 10 km s−1. Five different diagnostic methods were applied simultaneously to characterize the meteorite fragmentation and destruction in the ground test: short exposure photography, regular video, high-speed imaging with 10 kHz frame rate, thermography, and Echelle emission spectroscopy. This is the first time that comprehensive testing of various meteorite fragments under the same flow condition was conducted. The data sets indeed show typical meteorite ablation behavior. The cylindrically shaped fragments melt and evaporate within about 4 s. The spectral data allow the identification of the material from the spectra which is of particular importance for future spectroscopic meteor observations. For the tested ordinary chondrite sample a comparison to an observed meteor spectra shows good agreement. The present data show that this testing methodology reproduces the ablation phenomena of meteoritic material alongside the corresponding spectral signatures.
Constraints on Climate and Habitability for Earth-like Exoplanets Determined from a General Circulation Model

Published: March 2017

Abstract
Conventional definitions of habitability require abundant liquid surface water to exist continuously over geologic timescales. Water in each of its thermodynamic phases interacts with solar and thermal radiation and is the cause for strong climatic feedbacks. Thus, assessments of the habitable zone require models to include a complete treatment of the hydrological cycle over geologic time. Here, we use the Community Atmosphere Model from the National Center for Atmospheric Research to study the evolution of climate for an Earth-like planet at constant CO2, under a wide range of stellar fluxes from F-, G-, and K-dwarf main sequence stars. Around each star we find four stable climate states defined by mutually exclusive global mean surface temperatures (T
s); snowball (T
s ≤ 235 K), waterbelt (235 K ≤ T
s ≤ 250 K), temperate (275 K ≤ T
s ≤ 315 K), and moist greenhouse (T
s ≥ 330 K). Each is separated by abrupt climatic transitions. Waterbelt, temperate, and cooler moist greenhouse climates can maintain open-ocean against both sea ice albedo and hydrogen escape processes respectively, and thus constitute habitable worlds. We consider the warmest possible habitable planet as having T
s ∼ 355 K, at which point diffusion limited water-loss could remove an Earth ocean in ∼1 Gyr. Without long timescale regulation of non-condensable greenhouse species at Earth-like temperatures and pressures, such as CO2, habitability can be maintained for an upper limit of ∼2.2, ∼2.4, and ∼4.7 Gyr around F-, G-, and K-dwarf stars respectively, due to main sequence brightening.
Electric Current Filamentation Induced by 3D Plasma Flows in the Solar Corona

Published: March 2017

Abstract
Many magnetic structures in the solar atmosphere evolve rather slowly, so they can be assumed as (quasi-)static or (quasi-)stationary and represented via magnetohydrostatic (MHS) or stationary magnetohydrodynamic (MHD) equilibria, respectively. While exact 3D solutions would be desired, they are extremely difficult to find in stationary MHD. We construct solutions with magnetic and flow vector fields that have three components depending on all three coordinates. We show that the noncanonical transformation method produces quasi-3D solutions of stationary MHD by mapping 2D or 2.5D MHS equilibria to corresponding stationary MHD states, that is, states that display the same field-line structure as the original MHS equilibria. These stationary MHD states exist on magnetic flux surfaces of the original 2D MHS states. Although the flux surfaces and therefore also the equilibria have a 2D character, these stationary MHD states depend on all three coordinates and display highly complex currents. The existence of geometrically complex 3D currents within symmetric field-line structures provides the basis for efficient dissipation of the magnetic energy in the solar corona by ohmic heating. We also discuss the possibility of maintaining an important subset of nonlinear MHS states, namely force-free fields, by stationary flows. We find that force-free fields with nonlinear flows only arise under severe restrictions of the field-line geometry and of the magnetic flux density distribution.
Chondrule Accretion with a Growing Protoplanet

Published: March 2017

Abstract
Chondrules are primitive materials in the solar system. They were formed in about the first 3 Myr of the solar system’s history. This timescale is longer than that of Mars formation, and it is conceivable that protoplanets, planetesimals, and chondrules might have existed simultaneously in the solar nebula. Due to protoplanets’ perturbation on the planetesimal dynamics and chondrule accretion on them, all the formed chondrules are unlikely to be accreted by the planetesimals. We investigate the amount of chondrules accreted by planetesimals in such a condition. We assume that a protoplanet is in oligarchic growth, and we perform analytical calculations of chondrule accretion by both a protoplanet and planetesimals. Through the oligarchic growth stage, planetesimals accrete about half of the formed chondrules. The smallest planetesimals get the largest amount of chondrules, compared with the amount accreted by more massive planetesimals. We perform a parameter study and find that this fraction is not greatly changed for a wide range of parameter sets.
