Introducción: La adecuada nutrición en la adolescencia es de importancia para su crecimiento y desarrollo. Existen factores ambientales que no pueden evitarse, como la exposición a metales pesados a través de fuentes naturales como el agua. El arsénico es un metaloide que causa daños a la salud (alteraciones del estado nutricio, diabetes, cáncer) y ha sido encontrado en concentraciones superiores a las permitidas en el agua de consumo. Objetivo: Medir el efecto de una suplementación multivitamínica sobre el estado nutricio y la excreción urinaria de arsénico en adolescentes expuestos a este metal a través de agua de consumo. Métodos: Se realizó un estudio de intervención en 45 adolescentes, expuestos a arsénico en agua de consumo, a quienes se dio un suplemento multivitamínico diariamente, durante cuatro semanas. De forma semanal se evaluó el estado nutricio, y los niveles de arsénico en orina y en agua de consumo. Resultados: En la población de estudio se observó que el consumo nutrimental basal fue bajo para proteínas, fibra, ácido fólico, vitamina B2, B6, B12, E, C, selenio y hierro, incrementando su consumo a través del suplemento durante la intervención y con un aumento de aproximadamente de 1g/dL de hemoglobina en todos los participantes. Así mismo, al final de la intervención presentaron incremento de masa libre de grasa y disminución en el porcentaje de grasa corporal. Por otro lado, en cuanto a la excreción urinaria de arsénico se observó mayor eliminación de este metal [35.91 µg/g Cr (IC 95%=23.2-74.8 µg/g Cr)] desde la primera semana de intervención, la cual fue estadísticamente significativa en comparación con los niveles basales de arsénico urinario [43.2 µg/g Cr (IC95%=30.8-117.6 µg/g Cr) (p<0.05) con un promedio de agua con As de 96.2±7.5 µg/L. Conclusión: La suplementación multivitamínica de cuatro semanas en la población de adolescentes estudiada mejoró el estado nutricio y aumentó la excreción del metaloide de manera significativa en la primera y segunda semana post intervención.

Published: June 2018

Abstract
The rich oil accumulations in the southern Tamaulipas area in Mexico have been discussed in the literature for over 100 years. The first productive well in this field located in north-east Mexico was drilled in 1910, and the field has been producing commercially since then. More than a 100 years later, in 2013, the field started a new chapter under a different operating company, which began a push for the implementation of an operations excellence initiative among the stakeholders for which the first goal is production maintenance through increased uptime of the wells.
A key to success in this new chapter for the exploitation of the field is the implementation of a digital oilfield focused in linking operational philosophy with available technologies and telemetry systems to integrate the operations excellence initiative with the field's operational requirements.
Five workflows are implemented and working for the field. Each workflow complies with a target:
Well monitoring for progressive cavity pumps (PCPs): This workflow tackles the early detection of anomalies in operational variables for well performance. Well rate estimation for PCPs: This workflow calculates production rate estimates for PCP wells. Well status: This workflow provides the live determination of the well operational status. Production losses: This workflow provides the daily tracking of production performance. Integrated reservoir and production tracking: This workflow enables field-level integrated analysis for reservoir and production data.
Incorporation of this solution generates a collaborative working environment between field operators, engineering departments and asset management, promoting synergy to strive for operation excellence in a challenging operating and economic environment.
The implementation of this digital solution enables a new era for the operations of a 100-year-old brownfield in Mexico. Changing operational conditions and low-productivity wells producing with artificial lift systems are the key challenges to maintaining production in the field. The system allows for timely acknowledgement of the field operating conditions to take proactive actions thus strengthening the operations and supporting to meet the steadily growing production targets.
The components of the system can be replicated and tailored to the challenges faced in different operating conditions. Field instrumentation, available technology, and engineering processes are combined to work toward the goal of excellence in operations and returns.

Published: June 2018

The physics of superconducting films, and especially the role of
remanent magnetization has a defining influence on the magnetic fields
used to hold and manipulate atoms on superconducting atomchips. We
magnetically trap ultracold ^{87}87Rb
atoms on a 200 m wide and 500 m thick cryogenically cooled niobium
Z-wire structure. By measuring the distance of the atomcloud to the
trapping wire for different transport currents and bias fields, we probe
the trapping characteristics of the niobium superconducting structure.
At distances closer than the trapping wire width, we observe a different
behaviour than that of normal conducting wire traps. Furthermore, we
measure a stable magnetic trap at zero transport current. These
observations point to the presence of a remanent magnetization in our
niobium film which is induced by a transport current. This
current-induced magnetization defines the trap close to the chip
surface. Our measurements agree very well with an analytic predic tion
based on the critical state model (CSM). Our results provide a new tool
to control atom trapping on superconducting atomchips by designing the
current distribution through its current history.

Published: June 2018

AbstractUnderstanding the actual evapotranspiration (ET) variation of the sparsely distributed xerophytic shrubs is crucial to accurately upscale community ET to ecosystem scale. Here we quantified the actual ET of two dominant xerophytic shrubs of the Tengger Desert in northwestern China, i.e. Salsola passerina and Reaumuria soongorica, by using four large weighing lysimeters. The results showed that with the increase in precipitation from 140 to 171 mm in the year 2015/2016, the daily mean evaporation (E) of the bare area, and ET of the single shrub communities of S. passerina, R. soongorica, and the associated shrub community (S. passerina + R. soongorica) increased 50, 60, 44, and 47%, respectively; correspondingly, the total E and ET increased 49, 61, 44, and 47%, respectively. The variation of soil moisture within 0–40 cm depth plays a vital role in regulating the E and ET. The new shoot length, as one of important parameters of the xerophytic shrub, was significantly exponentially related to the cumulative ET. From the long- and short-term perspective, event-based precipitation and wind speed are the dominant driving factors behind changes in E and ET, respectively. Relative humidity is the main influencing factor for E and ET after a large rainfall event within 8 days.
Enhanced Microwave Absorption Properties of FeCo@TiO2 Core-Shell Nanoparticles
Authors: Gharaati Abdolrasoul , Ebrahimzadeh Majid 
Published: June 2018

Background:
Microwave absorbing nanocomposite is a kind of material that attenuates
the reflection of microwave radiation in the gigahertz frequency range. These materials consist of
dielectric and transition nanoparticles tend to exhibit attractive microwave absorption properties due to
their high permittivity and permeability loss factors.

Method:

The FeCo nanoparticles were prepared from the reduction of iron and cobalt ions with hydrazine.
Then, the FeCo@TiO2 core-shell nanoparticles synthesized by co-precipitation method and their
microwave absorbing performance are investigated. The phase composition, morphology and coercivity
properties of the nanoparticles were studied by X-ray diffraction (XRD), transmission electron microscopy
(TEM) and vibrating sample magnetometry (VSM). The composites of FeCo@TiO2 nanoparticles
with the ratio of 30 vol.% and paraffin wax (70 vol.%) in different thicknesses were prepared. The microwave
absorption properties of these composites were investigated in the frequency range of 2-18
GHz using the vector network analyzer.

Results:

These nanocomposites exhibit the excellent microwave absorption characteristics (reflection
loss<-20dB) in the bored band frequency range of 6-16 GHz with different absorber thicknesses of 1-
2.2 mm. The maximum absorption capability of -47.76 dB was obtained at the frequency of 7.92 GHz
with the thickness of 1.8 mm.

Conclusion:

Based on this study, it can be argued that the FeCo@TiO2 nanoparticles can be used for
the bored band and thin microwave absorbers.
Comparison of Dynamic Contour Tonometry and Non-contact Tonometry in Older Patients Presenting with Headache or Vision Loss
Authors: Ing Edsel , Zhang Angela , Michaelov Evan , Wang Wendy 
Published: June 2018

Background:
Dynamic Contour Tonometry (DCT) is touted to be the most accurate tonometer for Intraocular Pressure (IOP) measurement. Non-Contact “air puff” Tonometry (NCT) may be the most commonly used tonometer for screening of IOP. Elevated IOP is important to exclude in patients presenting with headache or vision loss.

Objective:
To determine the agreement between DCT and NCT.

Methods:
The IOP of adult patients 50 years of age or older presenting with headache or vision loss for possible temporal artery biopsy were prospectively recorded. NCT and DCT measurements were obtained within thirty minutes. The right eye IOP measurements were compared with paired t-test, and Bland- Altman plot analysis. The left eye IOP measurements were subsequently analyzed for confirmation of results.

Results:
There were 106 subjects with complete right eye data, and 104 subjects with complete left eye data. The average age was 72 years, and 70% were female. The NCT IOP was on average 3.9 mm Hg lower in the right eye, and 3.5 mm Hg lower in the left eye compared with DCT. (p<.001) In the right eye the Bland-Altman analysis showed the 95% agreement interval between the two tonometers was -2.5 to 10.4 mmHg and in the left eye -3.0 to 9.9 mmHg.

Conclusion:
The IOP from NCT and DCT should not be used interchangeably because their level of disagreement includes clinically important discrepancies of up to 10 mm Hg.

Authors: Koju Surendra , Makaju Ramesh 
Published: June 2018

Introduction: Hereditary spherocytosis is a red cell membrane disorder that causes hemolytic anemia. Due to defective cell membrane, red cells are spherical shaped and result in their early lysis. Osmotic fragility of spherocytic red cell is increased.
Case report: A 22 year old female presented with chief complain of abdominal pain. Initially she was diagnosed as cholelithiasis. Under laboratory evaluation she was found to be anemic with reticulocytosis. In peripheral blood smear, spherocytes were moderately distributed. Antihuman globulin test was negative but osmotic fragility was high. Hence, she was confirmed as case of hereditary spherocytosis.
Conclusion: Hereditary spherocytosis is a rare red cell disorder and its diagnosis can be made by osmotic fragility test.
Accounting History Research Topics—An Analysis of Leading Journals, 2006–2015
Authors: Spraakman Gary P. , Quinn Martin 
Published: June 2018

ABSTRACT
This paper analyzes and categorizes published research papers in three specialist accounting history journals—Accounting History, The Accounting Historians Journal, and Accounting History Review. A key objective is to highlight under-represented areas for future research. We inductively derive a categorization system, and classify over four hundred papers from 2006–2015 according to twelve categories. The results show some rather under-researched areas, namely religion and accounting education. Using statistical analysis techniques, we note similarities and differences across the three journals and suggest avenues for future researchers.
