Evaluating the surface temperature and vegetation index (Ts/VI) method for estimating surface soil moisture in heterogeneous regions
Authors: Liu Zhaofei , Yao Zhijun , Wang Rui 
Published: November 2017

Abstract
The surface temperature and vegetation index (Ts/VI) method is a remote sensing-based quantitative approach. It is widely used for estimating the evapotranspiration, evaporative fraction, and surface soil moisture (SSM). However, this method can only be used in flat regions. In this study, we investigated the effect of altitude when using the Ts/VI method for estimating the SSM in heterogeneous regions. The results showed that the temperature vegetation dryness index (TVDI) method performed poorly at estimating the SSM in the source region of the Yangtze River; there was a weak correlation with the observed SSM, and R2 was only 0.167. However, the performance of the method improved considerably when the effects of both altitude and frozen soil were considered; the TVDI had a strong correlation with the observed SSM, and R2 improved to 0.617. In the study area, the effects of altitude on the TVDI values were greater than those of the frozen soil. In general, the Ts/VI method can obtain satisfactory results in mountainous regions if the effects of both the altitude and frozen soil are considered.
Assessing the climate change impact on hydrological response in the Gorganrood River Basin, Iran
Authors: Rouhani Hamed , Jafarzadeh Marayam Sadat 
Published: November 2017

Abstract
A general circulation model (GCM) and hydrological model SWAT (Soil and Water Assessment Tool) under forcing from A1B, B1, and A2 emission scenarios by 2030 were used to assess the implications of climate change on water balance of the Gorganrood River Basin (GRB). The results of MPEH5C models and multi-scenarios indicated that monthly precipitation generally decreases while temperature increases in various parts of the basin with the magnitude of the changes in terms of different stations and scenarios. Accordingly, seasonal ET will decrease throughout the GRB over the 2020s in all seasons except in summer, where a slight increase is projected for A1B and A2 scenarios. At annual scale, average quick flow and average low flow under the B1, A1B, and A2 scenarios are projected to decrease by 7.3 to 12.0% from the historical levels. Over the ensembles of climate change scenarios, the simulations project average autumn total flow declines of ∼10% and an overall range of 6.9 to 13.2%. In summer, the components of flow at the studied basin are expected to increase under A2 and A1B scenarios but will slightly decrease under B1 scenario. The study result addresses a likelihood of inevitable future climate change.

Published: November 2017

Background:
It has been decades since natural biomaterials, including mushrooms, are examined
for antioxidant capacity to put them in the place of the synthetic antioxidants causing cancer.
Ganoderma lucidum Karst is an annual fungus reputed for possessing medicinal properties. The fungus
has a high potential to be used as a dietary supplement or a source of nutrients and antioxidant agents. It
has not been more than a decade since the scientists are working on the different medicinal properties of
the endemic Ganoderma lucidum in Iran. This study was conducted, in order to complete a part of this
goal and comparing the antioxidant potential of the endemic specimen from Iran with findings from
other countries. The aim of this investigation was to test the antioxidant properties, total flavonoid and
phenolic contents of various extracts of Ganoderma lucidum in the form of fruit bodies.

Methods:
Mushroom samples were extracted with chloroform, methanol and water by maceration
method. Ferric Reducing Antioxidant Power, DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2&amp;#039;-
azino-bis[3-ethylbenzothiazoline-6-sulphonic acid]) were methods used for antioxidant studies in this
work. Also, total flavonoid and phenolic contents of these extracts were evaluated.

Results:
The methanol extraction illustrated the highest radical scavenging capacity 21.51&#177;0.90 &amp;#181;moL
Trolox/g Ferric reducing assay. The best activities in ABTS and DPPH tests were obtained by chloroform
extracts with the 31.36&#177;2.30 &#181;moL Trolox/g and 6.07&#177;0.08 &amp;#181;g/mL, respectively. Also the chloroform
extraction of this fungus displayed the highest total phenolic and flavonoid content 167.75&amp;#177;1.27
GAE/g and 38.00&amp;#177;0.75 mg quercetin equivalents/g, respectively.

Conclusion:
The results displayed that Reishi might be proposed as a source of natural antioxidant
compounds and can be used as excellent food supplement.

Authors: Kamiya Seitaro , Yamada Maya , Washino Miki , Nakashima Kenichiro 
Published: November 2017

Description: Design methods of nanoparticle formulations are divided into break-down
methods and build-up methods. The former is further divided into dry and wet processes. For drug
nanoparticle preparations, the wet process is generally employed, and organic solvents are used in
most formulations.

Method:
In this study, we investigate the preparation of nifedipine (IB) and griseofulvin (GF)
nanoparticles without using organic solvent. Both IB and GF nanoparticles, with a mean particle size
of approximately 50 nm, were prepared without organic solvent by employing a combination of roll
milling and high-pressure homogenization.

Result:
The X-ray diffraction peak of the IB and GF samples prepared by roll milling was present at
a position (2θ) identical to that of IB and GF crystals, indicating that no peak shift was induced by
interaction with phospholipids.

Conclusion:
These findings demonstrate that most IB and GF nanoparticles exist as crystals in phospholipids.
CoFe2O4-MWCNTs Modified Screen Printed Carbon Electrode Coupled with Magnetic CoFe2O4-MWCNTs Based Solid Phase Microextraction for the detection of Bisphenol A
Authors: Avan Asiye Aslihan , Filik Hayati 
Published: November 2017

Background:
Bisphenol A (BPA) is an important intermediate in the industrial manufacturing
of either polycarbonate plastic or epoxy resins. Bisphenol A and its chemical derivatives are
endocrine-disrupting chemicals. BPA is a potent endocrine-disrupting compound (EDC) and its toxicity
is widely reported in the literature. Therefore, it is important to develop fast identification methods
for the monitoring of BPA in the environment.

Methods:
In this work, multi-walled carbon nanotubes decorated with cobalt ferrites (CoF) nanoparticles
were synthesized by a controlled co-precipitation reaction. The modified multi-walled carbon
nanotubes decorated with CoF nanoparticles were applied as a magnetic solid-phase microextraction
(M-SPME) sorbent for the extraction of trace levels of BPA from water samples. In detection step,
the CoF/MWCNTs modified screen-printed carbon electrodes (CoF/MWCNTs/SPCEs) (named CoFsensor)
were used for the electrochemical detection of BPA. The CoF/MWCNTs modified SPCEs
are found to give stable and reproducibility responses to BPA and the sensor exhibited good stability.
Finally, the established combined procedure was successfully applied to determine BPA in water
samples.

Results:
In this work, the magnetic CoFe2O4/MWCNTs nanoparticles were used as the electrode
modifier and sample pre-concentrator. Firstly, some important electrochemical parameters of the
modified electrodes were optimized and the calibration curve of the sensor showed a good linearity
in the range of 0.5-50 µM and the detection limit was 0.2 µM. Secondly, the important parameters
that affect the extraction performance were optimized. Under combined conditions, the calibration
graph for the determination of bisphenol A was linear in the range of 0.02-1.5 µM (4.56-342 µg/L)
and the detection limit was 0.01 µM. Finally, the combined system was successfully used for the
detection of bisphenol A in tap water, drinking water, mineral water with recoveries of 93-102%.

Conclusion:
A new determination system combined CoF-sensor with M-CoF-SPME was developed
for rapid, sensitive and selective detection of traces BPA in aqueous samples. The CoF/MWCNTs
exhibited high sensitivity toward BPA with a maximum adsorption capacity of 67.7 mg/g. The
nanoparticles were collected using a magnet and reused at least 10 times without substantial degradation
in the activity. The analytical method combined miniaturised systems both in sample preparation
and in detection stage, with the major advantage of avoiding costly and bulky or unmovable instrumentation.
Besides, the M-CoF-SPME-CoF-sensor combination detection system provided many
benefits such as cheapness, ease of operation, good sensitivity and repeatability. The determination
method developed in current study provides a new option for the determination of BPA in water
sample.

When Data Become Ubiquitous, What Becomes of Accounting and Assurance?
Authors: Borthick A. Faye , Pennington Robin R. 
Published: November 2017

ABSTRACT
Big Data and the data analytical software for analyzing it have developed far enough that some trends have emerged. People are clever. Leave them alone with resources and they will do interesting things with them, giving both intended and unintended consequences. This commentary stems from the 2016 Journal of Information Systems Research Conference (JISC2016) on Big Data. It highlights the landscape of Big Data, including how organizations are starting to use data in different ways. While it is true that some of what this commentary offers does not, strictly speaking, require Big Data with respect to volume, diversity, and structure, the connotations that Big Data bestowed have prompted new ways to stage and use data. For example, “70% of firms now say that big data is of critical importance to their firms” (Malone 2016). The articles in this issue were presented as papers at JISC2016. They treat different aspects of the growing availability and use of data in organizations.

OBJECTIVE
To assess national differences in diabetes care and quality of life (QOL) between individuals with long-standing type 1 diabetes (≥50 years) in Canada and the U.S.

RESEARCH DESIGN AND METHODS
Cross-sectional data from identical surveys administered in the Canadian Study of Longevity in Diabetes and the Joslin Medalist Study, collected in 2013–2016 and 2005–2011, respectively, were compared. Laboratory values and ophthalmic examination were completed by clinical care physicians for Canadians and the Joslin Clinic for Americans. Univariate comparisons and multivariable regression for HbA1c, QOL, insulin pump use, and coronary artery disease (CAD) were performed. Nephropathy, CAD, and peripheral arterial disease (PAD) were self-reported; neuropathy was defined by a Michigan Neuropathy Screening Instrument (Questionnaire component) score ≥3, and proliferative retinopathy was documented from ophthalmic examination. QOL was self-reported on an ordinal scale.

RESULTS
Three hundred sixty-one Canadians and 668 Americans had similar ages (mean 65.78 years [SD 8.67] vs. 66.38 years [7.66], P = 0.27) and durations of diabetes (median 53.00 years [interquartile range 51.00, 58.00] vs. 53.00 years [51.00, 57.00], P = 0.51). Canadians had higher HbA1c (mean 7.53% [SD 1.03] [59 mmol/mol] vs. 7.22% [0.98] [55 mmol/mol], P &lt; 0.0001), lower QOL (36.9% vs. 48.7% with “excellent” QOL, P = 0.0002), and less CAD (29.7% vs. 41.2%, P = 0.0003) and insulin pump use (43.3% vs. 55.6%, P = 0.0002). Other complication rates were similar. Residual differences for Canadians compared with Americans remained after adjustment for age, sex, CAD, PAD, education, and relevant a priori selected variables: 0.28% higher HbA1c (P = 0.0004); and odds ratios of 0.68 (95% CI 0.51, 0.90), 0.46 (0.31, 0.68), and 0.71 (0.52, 0.96) for higher QOL, CAD, and insulin pump use, respectively.

CONCLUSIONS
Although Canadians and Americans have similar rates of complications other than CAD, further research is required to understand why Canadians have higher HbA1c levels, lower QOL, and less insulin pump use.

También se discute cómo abordar el estudio de la vitalidad, desde la visión individual del arquitecto o diseñador hasta la visión colectiva que todos tenemos como miembros de un grupo, de una sociedad. Se ahonda así en la diferente visión que tienen distintos agentes de lo urbano a la hora de entender el concepto de vitalidad. Por ultimo, este trabajo señala un posible camino para estudiar el fenómeno de la vitalidad, combinando distintos puntos de mira y actores que intervienen en la ciudad, mediante un acercamiento transversal y multidisciplinar.
Diseño de un controlador adaptativo neuronal usando Filtro Kalman
Authors: Cano Diego Fernando 
Published: November 2017

El control, basado en modelo de referencia (MRAS), ha tenido gran acogida en los últimos años, especialmente en los campos de investigación e industria debido a su fácil implementación y capacidad para controlar diferentes procesos. Esta técnica no hace referencia a un método de diseño específico sino a una variedad de algoritmos que permiten la construcción de diversos controladores. Una de las características de esta técnica es el uso directo del modelo del proceso, el cual es utilizado para comparar la salida del sistema, con la del modelo, y así efectuar ajustes sobre los parámetros del controlador. Estos ajustes son conocidos como adaptación. Dada la existencia de diversas dinámicas dentro de los sistemas, se propone utilizar las redes neuronales como representación del sistema en consideración (caldera) de la misma manera se utilizan para encontrar el modelo inverso del sistema, el cual cumplirá la función de controlador; por otra parte, el algoritmo de adaptación de parámetros del controlador corresponde al Filtro Kalman Extendido (EKF), que permite obtener mejores resultados computacionales en comparación con otros métodos.

Gestión de la Seguridad y Salud en el Trabajo
Authors: Chávez Orozco César 
Published: November 2017

El presente trabajo tiene como propósito realizar un breve análisis de la presencia de los riesgos en los lugares de trabajo, su relación con la salud y la importancia de su control para garantizar la protección de la salud de los trabajadore y por ende de los bienes y recursos de la organización. Las exigencias legales cada día más estrictas, los requerimientos de competitividad y las exigencias de los trabajadores, hacen que día a día se incremente la necesidad de que las empresas gestionen sus riesgos.
La prevención no trata solamente de defender al trabajador frente a la amenaza del riesgo laboral, sino que trata de procurarle un resultado positivo de promoción de su salud e integridad, en definitiva, de su desarrollo personal.
El avance de la prevención que se manifiesta en los tiempos actuales como un salto hacia nuevas fronteras, ha promovido la integración de la gestión de la seguridad y salud en el trabajo en toda la gestión integral de la organización. Para conseguir esta integración, se han establecido varias herramientas que permiten realizar las actividades de prevención orientando siempre a la mejora continua.
Los sistemas de gestión de seguridad y salud laboral más difundidos en el Ecuador son: el sistema de administración de la seguridad y salud en el trabajo, promovido por la entidad aseguradora del país (IESS) y el estándar internacional OHSAS 18001:2007, promovido por el creciente interés de las empresas de disponer sistemas certificados.
Para la aplicación de estos modelos de gestión, es importante que la organización se vea como un sistema integral, en donde los procesos preventivos formen parte integrante de todos los procesos de la organización.

LA CRISIS DE LA ECONOMÍA CUBANA O LA CRISIS DE UNA CONCEPCIÓN DEL ESTADO
Authors: Salgado Defranc José 
Published: November 2017

Cuba importa el 84% de los alimentos que se consumen en el país, lo cual indica que este país ha perdido la soberanía y la seguridad alimentaria. La zafra del período 2009-2010 fue de aproximadamente 1’200.000 toneladas, magnitud parecida a la zafra alcanzada el año 1905. En 1957 existían casi 5 millones de cabeza de ganado con una población de 7 millones de habitantes, mientras que en la actualidad el país cuenta con unas 3’870.000 cabezas de ganado y la población se ha incrementado a 11’200.000 habitantes. Todos estos datos nos hacen pensar que Cuba debería implementar las reformas realizadas en China, aunque un mejor ejemplo sería Vietnam.
