THE ISSUE OF LEGAL SUBJECTITY OF MANAGEMENT BODIES AND STRUCTURAL UNITS OF A LEGAL ENTITY
Authors: Sichevliuk Volodymyr
Published: December 2019

The author notes that the law nature of a legal entity presupposes the presence in the internal space of this legal actor a number of local legal relationships, in which the sole and collective elements of its organizational structure are involved. All of them are endowed with the status of a participant (party) of this kind of legal relations and possess a certain individualized part of the legal subjectity, inherent for legal entity in general. Therefore, governing bodies and other internal structures of legal entities do not have their own legal subjectity. Through the organizational structure of the legal entity it is realized personal legal subjectity just of this entity in all dimensions of the latter's existence. Accordingly, the structural elements of a legal entity are also not endowed with the status of subject of law.
There are few essential features, characterizing the individual status of legal subjectity, inherent for the structural element of the legal entity. Firstly, the content and scope of the rights and obligations of such formation (so-called «individual legal capacity») is always limited in accordance with the list of functions, provided for it; secondly, so-called «individual active capacity» of a structural element of a legal entity is determined by the needs of the organization as a whole and is interdependent with the ability to act on its other internal entities; thirdly, the governing bodies and divisions of the legal entity are the operators of the active segment of its delictual capacity, but they are deprived of the opportunity to be held responsible for the offenses, committed by them (their individual status doesn’t support the segment of «passive delictual capacity» of the legal person).
The aforementioned individualization of the legal subjectity of governing bodies and structural subdivisions of a legal entity is their essential attribute which: а) creates the basis for effective internal corporate or administrative control over the activities of such entities, and b) allows to realize an external regulation of the volume of a legal subjectity potential of certain internal structural elements of a legal entity for the purpose of, among other aims, the implementation of actual public interests in their activity.

Authors: Aliyu Muhammad Mukhtar
Published: December 2019

This study investigated tutors’ experiences and perceptions of using a problem-based learning approach (PBL) in an ESL writing classroom. The participants of the study are two Nigerian tutors who facilitated an intact class of 18 second-year students in an English composition course which lasted for 12 weeks. Data were collected through semi-structured interviews. The tutors were interviewed after the implementation of the PBL process. The overall findings of the study show that the tutors have positive perceptions of the use of PBL in a writing classroom. Specifically, the findings reveal the tutors’ positive experiences and perception of the workshop conducted prior to the PBL process, the ill-structured problems presented to the students, tutor facilitation and students’ group activities. Finally, the paper gives some pedagogical implications which would give insight for better implementation of the PBL approach.

Authors: He Pingan , Hou Longao , Tao Hong , Dai Qi , Yao Yuhua
Published: December 2019

Backgroud:

The impact of cancer in society created the necessity of new and faster
theoretical models for the early diagnosis of cancer.

Methods:

In this work, a mass spectrometry (MS) data analysis method based on the star-like
graph of protein and support vector machine (SVM) was proposed and applied to the ovarian
cancer early classification in the MS data set. Firstly, the MS data is reduced and transformed into
the corresponding protein sequence. Then, the topological indexes of the star-like graph are
calculated to describe each MS data of the cancer sample. Finally, the SVM model is suggested to
classify the MS data.

Results:

Using independent training and testing experiments 10 times to evaluate the ovarian
cancer detection models, the average prediction accuracy, sensitivity, and specificity of the model
were 96.45%, 96.88%, and 95.67%, respectively, for [0,1] normalization data, and 94.43%,
96.25%, and 91.11% for [-1,1] normalization data.

Conclusion:

The model combined with the SELDI-TOF-MS technology has a prospect in early
clinical detection and diagnosis of ovarian cancer.
A Sequential Ensemble Model for Communicable Disease Forecasting
Authors: Sultana Nashreen , Sharma Nonita , Sharma Krishna Pal , Verma Shobhit
Published: December 2019

Background:

Ensemble building is a popular method for improving model accuracy for classification problems as well as regression.

Objective:

In this research work, we propose a sequential ensemble model to predict the number of incidences for communicable diseases like influenza, hand foot and mouth disease (HFMD), and diarrhea and compare it with applied models for prediction.

Methods:

The weekly dataset of the three diseases, namely, influenza, HFMD, and diarrhea, are collected from the official government site of Hong Kong from the year 2010 to 2018. The data was preprocessed by taking log transformation and z-score transformation. The proposed sequential ensemble model is applied to the processed dataset to predict future occurrences.

Results:

The result of the proposed ensemble model is compared against standard support vector regression (SVR) using different error metrics such as root mean square error (RMSE), mean absolute error (MAE) and mean absolute percentage error (MAPE). In the case of all the threedisease datasets, the proposed ensemble model gives better results in comparison to the standard SVR model.

Conclusion:

The main objective of this research work is to minimize the prediction error; the proposed sequential ensemble model has shown a significant result in terms of prediction errors.
Geminiviruses: Taxonomic Structure and Diversity in Genomic Organization
Authors: Kulshrestha Saurabh , Bhardwaj Abhishek , Vanshika
Published: December 2019

Background:

Geminiviridae is one of the best-characterized and hence, one of the largest
plant-virus families with the highest economic importance. Its members characteristically have
a circular ssDNA genome within the encapsidation of twinned quasi-icosaheadral virions (18-38 nm
size-range).

Objective:

Construction of a narrative review on geminiviruses, to have a clearer picture of their
genomic structure and taxonomic status.

Methods:

A thorough search was conducted for papers and patents regarding geminiviruses,
where relevant information was used to study their genomic organization, diversity and taxonomic
structure.

Results:

Geminiviruses have been classified into nine genera (viz., genus Begomovirus, Mastrevirus,
Curtovirus, Topocuvirus, Becurtovirus, Turncurtovirus, Capulavirus, Eragrovirus and
Grablovirus) having distinct genomic organizations, host ranges and insect vectors. Genomic organization
of all genera generally shows the presence of 4-6 ORFs encoding for various proteins.
For now, Citrus chlorotic dwarf-associated virus (CCDaV), Camellia chlorotic dwarf-associated
virus (CaCDaV) and few other geminiviruses are still unassigned to any genera. The monopartite
begomoviruses (and few mastreviruses) have been found associated with aplhasatellites and betasatellites
(viz., ~1.3 kb circular ssDNA satellites). Recent reports suggest that deltasatellites potentially
reduce the accumulation of helper-Begomovirus species in host plants. Some patents have
revealed the methods to generate transgenic plants resistant to geminiviruses.

Conclusion:

Geminiviruses rapidly evolve and are a highly diverse group of plant-viruses. However,
research has shown new horizons in tackling the acute begomoviral diseases in plants by
generating a novel bio-control methodology in which deltasatellites can be used as bio-control
agents and generate transgenic plants resistant to geminiviruses.

Acceptability and Use of Interactive Voice Response Mobile Phone Surveys for Noncommunicable Disease Behavioral Risk Factor Surveillance in Rural Uganda: Qualitative Study (Preprint)
Authors: Ssemugabo Charles , Rutebemberwa Elizeus , Kajungu Dan , Pariyo George W , Hyder Adnan A , Gibson Dustin G
Published: December 2019

BACKGROUND

There is need for more timely data to inform interventions that address the growing noncommunicable disease (NCD) epidemic. With a global increase in mobile phone ownership, mobile phone surveys can bridge this gap.

OBJECTIVE

This study aimed to explore the acceptability and use of interactive voice response (IVR) surveys for surveillance of NCD behavioral risk factors in rural Uganda.

METHODS

This qualitative study employed user group testing (UGT) with community members. The study was conducted at the Iganga-Mayuge Health and Demographic Surveillance Site (IM-HDSS) in Eastern Uganda. We conducted four UGTs which consisted of different categories of HDSS members: females living in urban areas, males living in urban areas, females living in rural areas, and males living in rural areas. Participants were individually sent an IVR survey, then were brought in for a group discussion using a semistructured guide. Data were analyzed thematically using directed content analysis.

RESULTS

Participants perceived that IVR surveys may be useful in promoting confidentiality, saving costs, and raising awareness on NCD behavioral risk factors. Due to the clarity and delivery of questions in the local language, the IVR survey was perceived as easy to use. Community members suggested scheduling surveys on specific days and sending reminders as ways to improve their use for surveillance. Social issues such as domestic violence and perceptions toward unknown calls, technological factors including poor network connections and inability to use phones, and personal issues such as lack of access to phones and use of multiple networks were identified as barriers to the acceptability and use of mobile phone surveys. However, incentives were reported to motivate people to complete the survey.

CONCLUSIONS

Community members reflected on contextual and sociological implications of using mobile phones for surveillance of NCD behavioral risk factors. The opportunities and challenges that affect acceptability and use of IVR surveys should be considered in designing and implementing surveillance programs for NCD risk factors.

Authors: Solís-Guzmán Celia Emma , Aguilar-Ayala Ismael , Molina González María Graciela
Published: December 2019

La concentración de la producción del fruto de granada roja ‘Apaseo Tardía’ ocurre en un periodo aproximado de 40 días; lo que afecta la economía de sus productores al tener que ofertar su producción a bajos precios. Por otra parte, la aplicación de fitohormonas al fruto después de la cosecha, como las auxinas, puede conservarlo con características de calidad adecuada por periodos de tiempo prolongado y de forma asequible para los consumidores. Esto permitiría comercializar los frutos de la granada roja fuera del periodo de cosecha, incrementando los precios de venta. La presente investigación se realizó con el objetivo de evaluar el efecto del ácido indol-3-butirico (AIB) sobre la calidad poscosecha del fruto de granada roja (Punica granatum) ‘Apaseo Tardía’. Los tratamientos evaluados fueron: 0, 20, 40 y 80 mg/L-1 de AIB. La unidad experimental consistió de un fruto con cinco repeticiones por tratamiento y el diseño experimental fue completamente al azar. La aplicación de AIB se realizó por inmersión durante 10 minutos. Las variables de respuesta evaluadas fueron masa (g), tamaño (cm) en diámetro y longitud del fruto, concentración de antocianinas totales, porcentaje de acidez titulable, concentración de ácido ascórbico, clorofilas a, b y total. Los resultados indican que el tratamiento de 20 mg/L-1 de AIB conservo significativamente el tamaño en longitud del fruto. En las otras variables evaluadas no se encontraron diferencias estadísticas significativas en ninguno de los tratamientos.

Authors: Iman Fauzul , Miarsyah Mieke , Sigit Diana Vivanti
Published: December 2019

Intention to act and environmental issues knowledge has been assumed as the two variables which affect people’s environmental behavior. This study aimed at determining the correlations between variables (i.e. intention to act, environmental issues knowledge, and environmental behavior) on biology teachers in State High Schools of Pandeglang Regency. This survey research used quantitative approach. The sample was 51 teachers chosen using simple random sampling.  Meanwhile, the population was 61 teachers in State High Schools of Pandeglang Regency. The data gained were analyzed using path analysis. The results showed that environmental knowledge gives direct impact on environmental behavior with coefficient value was 0.472. The same phenomena were also occurred in the intention to act towards the teachers’ environmental behavior (0.508). In addition, the intention to act was directly influenced by environmental knowledge (0.364), while the environmental behavior was indirectly affected by environmental knowledge (0.185). Thus, the findings of this study can be basic information to determine the most proper strategy to cultivate a good environmental behavior.

Aim. To study the contribution of biliary sludge (BS) to the development of chronic pancreatitis in patients with gallbladder sludge and verified chronic pancreatitis; to evaluate the clinical efficacy and safety of hymecromone therapy according to clinical and laboratory signs, as well as dynamics of gallbladder size and contractility.

Materials and methods. An open single-centre clinical trial included 30 patients with chronic pancreatitis (CP), which was diagnosed according to the Cambridge criteria. All patients received hymocromone (Odeston®) 400 mg tid for 3 weeks. An analysis of the efficacy and safety of the studied drug was performed on the 21st day of treatment based on the results of laboratory tests, abdominal ultrasound, cholecystography and endosonography of the pancreatobiliary zone, quality-of-life assessment according to the SF-36 questionnaire, the frequency and severity of adverse effects (AE).

Results. CP signs were found in 6.3 % of patients with gallbladder BS. CP was significantly more frequent in patients with putty-like bile (33.3 %, χ2 = 38.21, p < 0.00001). The area of the major duodenal papilla (MDP) was below normal in 78% of patients. According to factor analysis, monotherapy with hymocromone resulted in a decrease in abdominal pain, nausea, heaviness in the abdomen and bloating. By the end of the therapy, the quality of life according to the “BP” bodily pain scale of the SF-36 questionnaire significantly increased.

Conclusions. Biliary sludge (including undiagnosed forms during routine examination) was found to be a factor in the development of CP. The medical correction of biliary disorders in CP should include selective antispasmodics. Hymecromone therapy demonstrates a good level of tolerability and safety, normalizes the motor function of the biliary tract and sphincter tone over a short period of time, and relieves CP symptoms.

Published: December 2019

Introduction. Trichinellosis is a cosmopolitan anthropozoonosis, and is a
group of systemic diseases caused by larval forms of Trichinella. This is
one of the oldest and most controversial parasitic zoonoses that has been in
the forefront of veterinary, medical and biological research for many years.
Parasites from the genus Trichinella were diagnosed in more than one hundred
species of domestic and wild mammals and birds. The aim of this study was
economic evaluation of a program for monitoring and controlling Trichinella
in pigs. Materials and Methods. A systematic pest rodent control program
deemed suitable for monitoring and controlling Trichinella in pigs was
implemented in a representative test zone. The results of the pest rodent
control program were analyzed using cost-benefit analysis to determine if a
similar program would be suitable for a larger land area. Results and
Conclusions. Prior to pest control, the incidence of Trichinella in pigs
living in the test zone increased annually, while after systematic pest
rodent control, the incidence of Trichinella-positive pigs decreased. These
results, as well as relevant economic indicators, enabled us to design two
mathematical models describing the control and monitoring of Trichinella in
a larger land area. In this area, Srem Region, Serbia, a suitable
Trichinella control program in pigs is clearly justified because the profit
to cost ratio was positive for both models.
International Accounting Research: The Italian Context
Authors: Gotti Giorgio , Fasan Marco
Published: December 2019

Oftentimes, research ideas in the international accounting field arise from the comparison of different contexts and from the curiosity to understand how different constructs work in various settings. Despite knowledge and understanding of the institutional, cultural, and legal settings of countries are prerequisites for this kind of research, studies often focus on very narrow issues and do not allow a grasp of the big picture of the institutional feature of a country, and how this can influence managers' decisions related to accounting choices and disclosures. This paper aims at filling this gap and at fostering an understanding of the Italian institutional setting (e.g., culture, societal values, corporate governance, GAAPs, auditing, and tax regulations), thereby facilitating the work of international accounting researchers who wish to include Italian firms in their samples.
Big Data Analytics For Organizations: Challenges and Opportunities and Its Effect on International Business Education
Authors: Ali Twana Saeed , Kaya Tugberk
Published: December 2019

Big Data refers to large volumes of information. This information varies from pictures, videos, texts, audios and other heterogeneous data. In recent years, the amount of such big data has exceeded the capacity of online or cloud storage systems. The amount of data collected yearly has doubled in the past years and the concern for the volume of this data has reached its Exabyte yearly range. This paper focuses on the major issues and opportunities as well as big data storage with the aid of academic tools and researches conducted earlier by scholars for big data analysis. Modern learning environment (MLE) has to be understood in order to know how it supports learning in areas of big data such as university education systems. The utilization of online resources and web pages with laptops and mobile phones need to be understood as an attempt to integrate the modern learning environment and improve teaching in international bossiness. Big data can be fine-tuned and used to create new online learning programmers. Data collected by government departments, universities and institutions could be used as a new innovative learning system such as (MLE) which has a passive and active character i.e. it can be accessed anywhere at any time. This would also help in minimizing extended classroom activities because students would have controlled access to online knowledge from their homes
A professional learning program for novice online teachers: Application of professional development guidelines using threshold concepts and online learning perceptions
Authors: Northcote Maria , Gosselin Kevin P , Kilgour Peter , Reynaud Daniel , McLoughlin Catherine
Published: December 2019

The professional development of online teachers is now commonplace in most universities. Alongside the relatively straightforward decision to provide professional learning support for novice and experienced online educators within universities, decisions about the nature and content of such support are not always as clear cut. The study aimed to gather evidence about the experiences and views of current students and staff which, in turn, informed a set of pedagogical guidelines that could be used as the basis of professional learning programs for novice online teachers. Using a mixed methods research design, data were gathered using questionnaires, reflective journals and focus groups to determine the threshold concepts about online teaching, and perceptions of ideal online learning contexts. As well as identifying threshold concepts about online teaching and perceptions of teachers’ and students’ ideal views of online learning contexts (reported elsewhere), the study produced curricular guidelines to inform the design of professional development outputs for online teachers in higher education contexts. This article reports on an example of how these professional development guidelines were implemented at one higher education institution to provide wide-scale implementation of a professional development program for academic staff engaged in online teaching.
Identifying Significant Personal and Program Factors that Predict Online EdD Students’ Program Integration
Authors: Rockinson-Szapkiw Amanda , Holmes Joe , Stephen Jacqueline
Published: December 2019

Based on a synthesis of persistence theory and the empirical literature, an online doctoral program integration model was developed using data from 232 online EdD students. A predictive, correlation design and regression analysis were used to examine if personal factors (sex, race, age, marital status, and presence of children in the home) and program factors (stage in doctoral journey, synchronous interactions, cohorts, and orientations) could predict program integration. The entire model was significant. The variables of sex, race, participation in a cohort, and engagement in synchronous communication individually contributed to the variance in program integration.

Published: December 2019

We explore new tools and methods for learning designers and researchers to characterize pedagogical approaches that are applied to the design of MOOCs. This paper makes three main contributions to literature on MOOC design and evaluation: (1) an Expanded Assessing MOOC Pedagogies instrument for use by learning designers and researchers within their own contexts, (2) a demonstration of how nearest neighbor cluster analysis can be used to identify pedagogically similar MOOCs, and (3) a preliminary analysis of the clusters to account for features and factors that contribute to pedagogical similarity of MOOCs within clusters. This work advances research in the development of MOOC typologies, to allow learning designers and researchers to ask nuanced questions about pedagogical aspects of MOOC design.
Space Travel, A Story's Tale, The Seeds, Palmyra: The Fallen Ruins

Space Travel

 

There is a sound; of a certain kind.

Permeating all space. A traveller’s hummings.

A low whistle-like, melancholic.

Or akin the humms of a great engine.

 

It’s more a song than a sound.

As if, a far forgotten home, calls.

Incessant, it gives a backdrop of notes,

To the bleak darkness of space.

What hears one, the others hears not.

For the sound, is not a song, heard by all the same.

Instead, it speaks, not in words but through feelings.

For each, it brings a different message.

 

In the midst of fervent activity,

It summons the mind to listen.

For in space, one must learn to take,

The guidance from the ever-present singer.

 

The same sound, I heard in the womb.

Heard it, in passionate exercise of love.

Unmistakably, it was there, around my death-bed

A friendship forged in infinity.
Apology strategies in English and Vietnamese
Authors: Lau Thu
Published: December 2019

The paper examined the differences in apology strategies between native speakers of English and advanced Vietnamese ESL learners as well as the factors that might result in those differences through discourse completion tests (DCTs). The data were coded in terms of five apology strategies, and were analyzed according to four situational categories in relation to age, dominance, social distance, and weight of offence. The result indicated that the apologies of the Vietnamese ESL learners showed more politeness and respect for people from higher status, closeness to a friend, less courtesy to an equal and less respect (but greater intimacy) for their kid, a family member. By contrast, the degree of politeness, sincerity and respect of the apologies of the native speakers depended heavily on the weight of offence and the situation itself. The acts of apologizing of the Vietnamese group were significantly influenced by the hierarchical culture of Vietnam, and their restricted linguistic competence as well.

Published: December 2019

The trend of initiating art design carrying wayang as the theme, is an attempt initiated by young generation that is worth-appreciated. However, the process of at design-making itself mostly does not genuinely pay attention to the essentials that each wayang figure has. Omitting or replacing one of the elements of Wayang Purwa could possibly change the values of wayang itself. This study is conducted to arrange a representative figure of Wayang Purwa, which is, Pandawa gagrak Surakarta as the principle of the design making without excluding the meanings and identities of the character. The method used in this study is qualitative, obtained from various references, such as; books, articles, and journals related to the Pandawa gagrak Surakarta figure, and interview with Bambang Suwarno, as a puppeteer as well as a leather wayang crafter. The result of this research is a reference of the Pandawa Lima and Gatotkaca figures design, as mostly used in various media.

El objetivo del presente estudio fue desarrollar protocolos base de preparación de esporas de micorriza arbuscular (MA) para su observación en el microscopio electrónico de barrido (MEB) y de tinción vital basada en la reacción enzimática con Diacetato de Fluoresceína (FDA). La microscopía electrónica es una de las técnicas más utilizadas para la caracterización morfológica de esporas de MA; no obstante, los protocolos reportados en trabajos previos no son descritos a detalle y tampoco son válidos para todos los tipos de muestras. Para evaluar la vitalidad de las esporas de MA, se emplean colorantes vitales como el FDA, el mismo que es convertido a un producto fluorescente por la actividad de diferentes enzimas localizadas en la membrana celular. En este trabajo se empleó un protocolo de limpieza de esporas con una solución de Tween 20 (3.75% V/V) y un proceso de deshidratación en un desecador de vidrio para su observación en el MEB. Adicionalmente, se trató las esporas con una solución de FDA (25 µM) para observarlas en el microscopio de fluorescencia y determinar su vitalidad. El protocolo de preparación utilizado para la visualización de las esporas de MA con el MEB nos permitió observar todas las estructuras. En cuanto a la tinción vital, se concluyó que el método es efectivo para esporas producidas in vitro y que no se encuentran en estado de latencia.

El objetivo del presente trabajo de investigación es la determinación cuantitativa de la hiperacumulación de los metales pesados como níquel, arsénico, cadmio, mercurio, plomo y cromo en los tallos y raíces de la planta acuática con características fitodepuradadoras conocida como Schoenoplectus californicus o totora, ubicada en las zonas bentónicas de la Vertiente Apangora  del Lago San Pablo de Imbabura-Ecuador. Se utilizó el método instrumental de espectroscopia de absorción atómica en horno de grafito y generador de hidruros; el primero para la determinación de las concentraciones de níquel, cadmio, cromo y plomo, y el segundo para determinar las de arsénico y mercurio. Como resultado se ha encontrado que, en las raíces, existen mayores niveles de níquel, arsénico, cadmio y mercurio en comparación con las concentraciones obtenidas de estos metales pesados en los tallos, mientras que no se han detectado valores de cromo y plomo en esta planta acuática. Por lo tanto, Schoenoplectus californicus es una planta hiperacumuladora; las elevadas concentraciones acumuladas de níquel, arsénico y cadmio se encuentran por encima del umbral de hiperacumulación y esta propiedad podría permitir que sea empleada en la descontaminación de suelos y en la fitominería.

El cálculo de la Huella Ecológica es una metodología que da cuenta de la cantidad de recursos que se están extrayendo de la naturaleza y a su vez la capacidad de ésta para reinsertarlos en el medio para llegar al equilibrio, expresada en hectáreas por persona y año a nivel local o global, en esta constante alteración del ambiente por las actividades antropogénicas se establece un monitoreo de la situación real de la sociedad-naturaleza, a este proceso se han sumado las universidades.Es así como en la Universidad Técnica del Norte (UTN) campus El Olivo, se determinó la Huella Ecológica con el propósito de desarrollar alternativas encaminadas a reducir el consumo de recursos y desechos, en base a indicadores directos de consumo como: agua, electricidad, papel y producción de desechos urbanos e indicadores indirectos como: cálculo de las emisiones de CO2 del transporte que utiliza el personal y estudiantes.Del análisis preliminar se obtuvo que la Universidad Técnica del Norte necesita 2.182,43 hectáreas (ha) y de unas 2.924,45 hectáreas globales (hag) para que capte su CO2 producido por todos los indicadores utilizados. Relacionando la cantidad preliminar de hectáreas requeridas y las que posee la universidad (636,5 ha) se presenta un déficit de 1.545,93 ha. Con esto se determinó que la Huella Ecológica de la Universidad Técnica del Norte para una población de 8994 es de 0,172 ha, la misma que está muy por debajo de la huella ecología del país que es de 1,19 ha.

A fin de evaluar la producción del pasto miel por efecto de la fertilización de NPK y enmienda química, importante fuente para la ganadería del sector de Noroccidente, Pichincha-Ecuador, se realizó esta investigación con 5 niveles de N, P y K (0, 50, 100, 150 y 200 kg ha-1), aplicados después de una enmienda con dosis de 1.5 t ha-1 de cal y 0.5 t ha-1 de yeso agrícola, bajo un diseño de bloques completos al azar, en arreglo de diamante doble modificado con tres repeticiones. Las variables evaluadas de la producción forrajera fueron altura de planta, materia verde y materia seca. La aplicación de los niveles de NPK, determinaron que los tratamientos T3 (N100P80K80) y T10 (N100P160K80) con 75.3 y 74.8 t ha-1 de forraje, respectivamente alcancen las mayores producciones. En producción de masa seca o fibra, el T3 y T4 (N150P80K80) fueron los mejores tratamientos con alrededor de 18.6 t ha-1. El suelo estudiado fue ligeramente ácido con pH 5.7 antes del encalado, pH 6.44 después del encalado y pH 5.75, al final de la investigación. De ahí que la acidez fue uno de los problemas principales de este suelo, colaborado por el elevado contenido de hierro entre 335 a 433 ppm, aunque por efecto de las enmiendas bajó a 226 ppm de Fe. La enmienda también incrementó el contenido de las bases de Ca, Mg y ligeramente el K. En cuanto al N, tuvo una tendencia creciente en el suelo durante los cuatro cortes llegando a un contenido promedio de 68.7 ppm de N, que corresponde a un rango mediano a alto.

La biodisponibilidad de los metales pesados ha sido ampliamente estudiada en los últimos años, debido fundamentalmente a su toxicidad para los ecosistemas naturales y para los seres vivos. En este trabajo, se estudió el efecto estacional sobre el proceso de piritización del Fe, Mn y dos metales traza biolimitantes (Cu y Co) en los sedimentos de la laguna de Vixán (NO de la Península Ibérica). Los resultados muestran una intensa piritización del Fe y Mn (en general >60%) en los núcleos estudiados en ambas épocas del año 2011 (marzo y agosto). El Cu y Co presentaron un comportamiento diferente, mostrando una marcada variación estacional en superficie y una intensa piritización en profundidad (>25 cm).

En los últimos años se ha producido un crecimiento acelerado de la población de algunas ciudades del Ecuador, entre ellas la ciudad de Loja. Este aumento en el número de habitantes lleva asociado el incremento en el parque automotor que ha creado una amplia gama de problemas de tráfico, debido entre otros a la inadecuada re-programación y calibración de los semáforos existentes. Esto produce una aglomeración vehicular sobre todo en las horas pico que se evidencia no sólo en el centro sino en toda ciudad.Con la finalidad de presentar una solución a los problemas de tráfico de la ciudad de Loja, se ha desarrollado un proyecto que tiene como objetivos organizar y distribuir el flujo vehicular de acuerdo a la necesidad y al espacio disponible en las vías públicas. Para ello se han desarrollado 2 modelos de ordenación del tráfico que atienden a 2 situaciones de la ciudad.El proyecto se inicia mediante la realización de un catastro de la señalética vertical y horizontal con información georreferenciada. Asimismo, se realizó un estudio de la situación actual del tráfico de la ciudad a partir de aforos vehiculares en puntos estratégicos y encuestas origen-destino con recopilación de información de tramos intermedios.Con esta información se establecieron modelos de tráfico para 2 escenarios: (1) modelización del estado actual del tráfico en la ciudad y calibración de los semáforos para esta situación y (2) inclusión del proyecto de Regeneración Urbana que implica la peatonalización de varias calles modelizando esa situación y calibración de los semáforos para este escenario. Finalmente se realizaron 3 análisis microscópicos en puntos conflictivos que conllevan la resolución del conflicto.El resultado de los modelos calibrados y de los análisis microscópicos implica una solución óptima que resuelve los problemas de tráfico de la ciudad de Loja.
