Published: February 2019

Summary
Numerous saturation indices and computer algorithms have been developed to determine whether, when, and where scale will form. However, scale prediction can still be challenging because the predictions from different models often differ significantly at extreme conditions. Furthermore, there is a great need to accurately interpret the partitioning of water (H2O), carbon dioxide (CO2), and hydrogen sulfide (H2S) between different phases, as well as the speciations of CO2 and H2S. This paper summarizes current developments in the equation-of-state (EOS) and Pitzer models to accurately model the partitioning of H2O, CO2, and H2S in hydrocarbon/aqueous phases and the aqueous ion activities at ultrahigh-temperature, ultrahigh-pressure, and mixed-electrolytes conditions. The equations derived from the Pitzer ion-interaction theory have been parameterized by regression of more than 10,000 experimental data from publications over the last 170-plus years using a genetic algorithm on the supercomputer DAVinCI at Rice University. With this new model, the 95% confidence intervals of the estimation errors for solution density are within 4×10–4 g/cm3. The solubility predictions of CO2 and H2S are accurate to within 4%. The saturation-index (SI) mean values for calcite (CaCO3), barite (BaSO4), gypsum (CaSO4·2H2O), anhydrite (CaSO4), and celestite (SrSO4) are accurate to within ±0.1—and for halite the values are within ±0.01—most of which are within experimental uncertainties. This model accurately defines the pH value of the production tubing at various temperature and pressure regimes and the risk of H2S exposure and corrosion. Furthermore, our model is able to predict the density of soluble chloride and sulfate (SO42−) salt solutions within ± 0.1% relative error. The ability to accurately predict the density of a given solution at temperature and pressure allows one to deduce when freshwater breakthrough will occur. In addition, accurate predictions can only be reliable with accurate data input. The need to improve the accuracy of scale prediction with quality data will also be discussed.

Authors: Xu Yu-Fen , Xu Yao , Li Xia , Yang Xin-Mei 
Published: February 2019

Objective: To determine the levels of α-1 acid glycoprotein (ORM1) in the sera of advanced lung adenocarcinoma (LUAD) patients with epidermal growth factor receptor (EGFR) mutation before treatment and after acquirement of EGFR tyrosine kinase inhibitor (EGFR-TKI) resistance, and to explore the clinical cut off value of ORM1 for targeted therapy resistance in LUAD.Methods:Enzyme-linked immunosorbent assay was used to determine serum ORM1 levels. Receiver operating characteristic curve was applied to evaluate the serum ORM1 level in the resistance of EGFR-TKI and the cut off value of ORM1 for the diagnosis of EGFR-TKI resistance.Results:The serum ORM1 concentrations in the healthy group, before and after drug resistance were 1.687 ± 0.103, 1.868 ± 0.101, and 1.731 ± 0.088 µg/ml, respectively. The serum ORM1 concentrations before and after drug resistance were higher than that of the healthy group, whereas the serum ORM1 concentrations in the resistant group were lower than those before drug treatment. In comparison to healthy group, the area under curve (AUC) of the serum ORM1 concentration was 0.918 ± 0.029 with sensitivity of 90.5% and specificity of 78.6% in the patient before EGFR-TKI treatment, while the AUC was 0.644 ± 0.062 with sensitivity of 69.0% and specificity of 66.7% in the resistance group. When compared to those before treatment, the AUC of serum ORM1 concentration was 0.880 ± 0.038 with a sensitivity of 92.9% and specificity of 73.8% in the resistance group. The cutoff value of serum ORM1 was 1.778 µg/ml for advanced EGFR-positive LUAD and 1.723 µg/ml after resistance to EGFR-TKI.Conclusion:Serum ORM1 has an important diagnostic value for the diagnosis of EGFR-positive LUAD and EGFR-TKI resistance in patients especially with advanced EGFR-positive LUAD. Our findings suggest that serum ORM1 is a biomarker in the prediction of EGFR-TKI resistance in EGFR-positive LUAD.
Route Aggregation Approach - An Efficacious Technique for Energy Enrichment
Authors: Zafar Sherin , Mehta Deepa 
Published: February 2019

Background:
Recent years have accentuated a remarkable rise in the popularity in the
field of mobile computing owing to the size reduction of the computing devices and it is also contributed
by the exceptional increase in the processing power availability of mobile laptops rendering
various computer applications to reach the ever-rising population segment. This increase in the
number of users poses more challenges in the field of networking. The various most specific constraints
that exist in the wireless mobile infrastructure-less networking environment having compact
batteries as the storehouses of power are power consumption and energy enrichment.

Methods:
The application of Route Aggregation in MANET thrives to improve the energy efficiency
in MANET by aggregation of routes and therefore achieving a significant saving in the
scarce resources. The methodology takes into account a Hybrid protocol, Zone Routing Protocol
with aggregated routes and selection of a Head in the aggregation Zone. The Head now takes the
responsibility of the routes and the data delivery along the routes within the aggregation Zone. The
formation of such Heads and Aggregation Zones reduces the energy dissipated at each node while
route discovery phase as the routes are readily available at the Head. The procedure thus proves effective
in saving energy as well as bandwidth. Aggregation has so far has been able to curb the
problems caused in order to improve the scalability of the network. This paper studies and analyses
various aggregation techniques applied in Mobile Ad-hoc Network (MANET) points out the improvements
in various QOS parameters resulted due to the application of aggregation on routes, data
and address in the field of MANETs.

Results:
The results of graphs validate the proposed approach and specify improvement of energy
consumption which is the need of hour. The results also justify the novel approach by varying various
parameters like number of nodes, pause time and simulation time showing improvement in average
energy consumption for the novel RA-ZRP approach.

Conclusion:
The random cluster head selection based routing approach also referred as route aggregation
approach is used for energy enhancement which is depicted in section above. NS2 simulated
results presented in this paper validate the proposed approach. The ZRP-RA based random
cluster selection energy enrichment approach helps in reducing the various control and routing
overheads involved in the functioning of ZRP. It also reduces the number of route requests to be
sent and thus superfluous route requests can be avoided and thus saving in bandwidth is achieved
also the reduction in the routing and control overhead reduces the probability of collisions and thus
the data is effectively forwarded to the destination. This also helps improve latency as the queuing
up of data packets is lessened owing to the less overhead.
Analysis of Absorptive Nickel Grating with a Dielectric Layer
Authors: Zhiwen Wang , Wei Yuan , Qianjian Guo 
Published: February 2019

Background:
Nickel grating absorber has been studied and shows good absorption property
in the visible band. In order to further improve the absorption performance, reflection should be reduced,
and anti-reflection layer should be added upon or under the gratings.

Method:
In this paper, the dielectric layer is added between and upon the nickel gratings. Equivalent
medium theory is used to analyze the role of dielectric layer on absorption mechanism of nickel gratings.
photoresist is used to illustrate the possible practical usage of the proposed method.

Results:
Absorption efficiency of TM (transverse magnetic) and TE (transverse electric) polarization
show growing trend with the increase of refractive index of the dielectric material. PMMA and TU7
are chosen as the dielectric material. The simulation results show that TM absorption reduced slightly
in visible band, and improved by up to 86% in the near infrared region. TE absorption shows up to
79% improvement in the whole visible to near infrared waveband.

Conclusion:
Nickel grating based broadband absorber is analyzed in this paper. Dielectric layer is
added upon the gratings, and act as the anti-reflection layer. The refractive index and layer thickness is
analyzed by using equivalent medium theory. Dielectric material that has high refractive index is more
desired. The designed nickel grating shows high absorption property from 450nm to 800nm for both
TM and TE polarization.

Published: February 2019

Background: HIV / AIDS is still a global health problem which needs to be addressed including prevention of HIV / AIDS transmission from mother to child. Prevention of transmission is carried out by implementing the Prevention of Mother to Child Transmission or PMTCT program. The PMTCT program is considered successful in reducing the risk of mother-to-child transmission, but this has not been done well and thoroughly, various kinds of challenges have occurred in the implementation of the PMTCT program.Objective: To know the challenges that occur in implementing the PMTCT programMethod: This study uses a systematic review based on Preferred Reporting Items For Systematic Reviews & Meta-Analyzes (PRISMA) to identify all the literature published using relevant keywords.Results: challenges in implementing the PMTCT program are the lack of information on HIV treatment, lack of family support, the heavy workload experienced by health workers and the limited availability of HIV testing equipment and drug stocks.Conclusion: The success of efforts to prevent HIV / AIDS transmission from mother to child does not depend on one party only, but involves several parties, the active role of health workers in providing education and information about HIV / AIDS to mothers and their families is not enough but must be added with active roles and support from family members to HIV mothers as the primary motivator for good behavior in accordance with the guidelines for PMTCT.
Convergencia partidaria y cambio social. El caso de México (1982-2010)
Authors: Johansson Mondragón Steven Iván 
Published: February 2019

El presente trabajo analiza la vinculación entre la convergencia partidaria y los cambios sociales en México. Aun cuando el núcleo central de la teoría parece poco adecuado para dar cuenta del caso mexicano (la estructura social mexicana está lejos de estar dominada por sus clases medias), no cabe duda que algunos de los cambios experimentados por esta sociedad (como la evolución, durante las últimas décadas, de la relación de fuerzas entre el capital y el trabajo) sí pueden contribuir a explicar la convergencia ideológico-programática de los partidos políticos en México.<br />
