Authors: Permana Ryan J. , Azaria Cherry , Rosnaeni Rosnaeni 
Published: January 2018

“Jati Belanda” leaves (Guazuma ulmifolia Lamk.) possesses antidyslipidemia effect and in this study we assessed the effect of "Jati Belanda” leaves ethanol extract in delaying the progression of atherosclerosis in aorta of the rats.Thirty atherosclerosis animal models were divided into six groups, which are three variant dose of “Jati Belanda” leaves (EEDJB 1-2-3), standard control (SC), negative control (NC) and Comparative control/ CC (simvastatin). The parameters measured were the wall thickness and lumen diameter (both in mm), and the amount of foam cells. The result for Kruskal Wallis test showed highly significant differences (p=0.00) of wall thickness Dose2 (0.056 mm) and Dose3 (0.056 mm) compared to NC (0.075 mm) and non-significant compared to CC (0.055 mm). ANOVA result for lumen diameter, p=0.773. ANOVA result for foam cells amount, p=0.000, Duncan test showed significantly different between EEDJB and NC group.It is concluded that “Jati Belanda” leaves ethanol extract reduced aortic wall thickness and the amount of foam cells, but did not increase lumen diameter on the athersclerotic aorta, and had an equal therapeutic effect compared to simvastatin in delaying the progression of atherosclerosis. Keywords: atherosclerosis, Jati Belanda, wall thickness, lumen diameter, foam cell
The Value of Holter Monitoring in the Assessment of Non-Specific Symptoms
Authors: Nassir Shokry Faaz 
Published: January 2018

Background: To assess the importance of Holter monitoring in evaluation of non-specific symptoms (like presyncope, dizziness, palpitations, syncope, etc.).
Patients and Methods: This is an observational , prospective descriptive study which was conducted at Shaheed Al-Mihrab cardiac centre at Babylon City - Iraq in which 100 patients referred from the consultation department for the assessment of non-specific compliants were included in this study . Holter monitoring was done for all patients after initial evaluation. Holter monitoring was accomplished using GE Holter system with two channels and five leads, attached to the anterior chest wall. The recorder was attached to a strap, which was attached to the patient shoulder. The recording was started in the morning at hospital working hours and the patient was allowed to go home and to resume his normal activities. He was advised to maintain his activity and asked to return back at the same time next day.
Results: 87% of patients have less than 10% premature ventricular ectopics as an isolated event while 90% of the patients have Supraventricular arrythmias less than 10% as isolated events. The mean minimum heart rate was 47 , mean maximum heart rate was 117 and mean average heart rate was 65 . 18 % of patients have ST segment Shift in which 4% were ST-segment elevation and 14% were ST segment depressions.
Conclusion: Holter monitoring was found to have no important role for the early diagnosis of arrhythmias or ischaemia as a cause of compliant in patients with non-specific symptoms

AbstractThis paper presents the fabrication of nanoceramic layers by electrophoretic deposition. Suspensions containing TiO2 nanoparticles were prepared in different organic solvents, such as ethanol, methanol, acetone, and acetylacetone. During electrophoretic deposition, the color of organic media at around 200 V cm−1 began to change. This phenomenon is related to the anodic dissolution, which may assist deposition processes in some cases. Deviation from Hamaker's equation was observed upon measuring the deposited mass using different anode electrodes. Atomic absorption spectroscopy was used to measure concentrations of chemical elements liberated in the suspension due to the dissolution of anodes. These results show that anodic dissolution directly affects deposition rate. We observed this event even in the absence of powder and additives. Therefore, this is advantageous if anodic contaminants are not effective or influential.

Published: January 2018

AbstractThe present study aimed at investigating the effects of different additives and heat treatments on the mechanical properties of Al-2.4 %Cu-1.2 %Si-0.4 %Mg-0.4 %Fe-0.6 %Mn alloy, a casting alloy intended for automotive applications. The research was accomplished through a study of the tensile properties in both as-cast and heat-treated conditions, where the effects of different heat treatments, i. e., T5, T6, T62 and T7, commonly applied to aluminum casting alloys were evaluated at ambient and at high temperature (250 °C), using different holding (stabilization) times at testing temperature. Six alloys were prepared using 0.15 wt.% Ti grain-refined alloy – considered as the base alloy B0, and alloys B1 and B2, and D0, D1, and D2 containing various amounts of Ni, Cr, V, Zr and La, added individually or in combination. The D-series alloys had a higher Si content of 8 wt.%. The results showed that T6 and T62 treatments provide the best improvements in strength at room temperature. At high temperature, the tensile properties vary depending on the stabilization time and heat treatment. The best alloy quality is provided by B1 and D1 alloys in T62 (444/368 MPa) and T7 (430/360 MPa) conditions, respectively.

Published: January 2018

Background: Fourth-line therapy (4LT) in the treatment of metastatic renal cell carcinoma (mRCC) varies significantly due to the lack of data and recommendations to guide treatment decisions. Objective: To evaluate the use and efficacy of 4LT in mRCC patients. Methods: The International mRCC Database Consortium (IMDC) dataset was used to identify patients with mRCC treated with 4LT. This is a multicenter, retrospective cohort study. Overall survival (OS) and progression-free survival (PFS) were calculated using Kaplan-Meier curves. Patients were evaluated for overall response. The six prognostic variables included in the IMDC prognostic model were used to stratify patients into favorable-, intermediate- and poor-risk groups. Exploratory analyses were performed examining the elderly (>70 years old) and non-clear cell RCC subgroups. Proportional hazards regression modelling was performed adjusting these covariates by IMDC criteria measured at initiation of 4th line therapy. Results: 7498 patients were treated with first line targeted therapy and out of these 594 (7.9%) received 4LT. Everolimus was the most frequently used 4LT (16.8%). Sorafenib, axitinib, pazopanib, sunitinib and clinical trial drugs were also used in >10% of patients. The OS of patients on any 4LT was 12.8 months, with a PFS of 4.4 months. The overall response rate (ORR) was 13.7%. Favorable-risk patients using IMDC criteria (5%) displayed an OS of 23.1 months, intermediate-risk patients (66%) had an OS of 13.8 months and poor-risk patients (29%) had an OS of 7.8 ( p < 0.0001) months. Age >70 years and non-clear cell histology did not impact OS. Our study is limited by its retrospective design. Conclusions: 4LT use appears to have activity in mRCC patients. The IMDC continues to be of prognostic value in the fourth-line setting for OS. This study helps to set a benchmark for response rate and survival for which clinical trials can plan sample size calculations and aim to improve upon.
Gaia DR1 Evidence of Disrupting the Perseus Arm

Published: January 2018

Abstract
We have discovered a clear sign of the disruption phase of the Perseus arm in the Milky Way using Cepheid variables, taking advantage of the accurately measured distances of Cepheids and the proper motions from Gaia Data Release 1. Both the Galactocentric radial and rotation velocities of 77 Cepheids within 1.5 kpc of the Perseus arm are correlated with their distances from the locus of the Perseus arm, as the trailing side is rotating faster and moving inward compared to the leading side. We also found a negative vertex deviation for the Cepheids on the trailing side, −27.°6 ± 2.°4, in contrast to the positive vertex deviation in the solar neighborhood. This is, to our knowledge, the first direct evidence that the vertex deviation around the Perseus arm is affected by the spiral arm. We compared these observational trends with our N-body/hydrodynamics simulations based on a static density-wave spiral scenario and with those based on a transient dynamic spiral scenario. Although our comparisons are limited to qualitative trends, they strongly favor the conclusion that the Perseus arm is in the disruption phase of a transient arm.
Unique extrication structure in a new megaspilid, Dendrocerus scutellaris Trietsch &amp; Mikó (Hymenoptera: Megaspilidae)
Authors: Trietsch Carolyn , Mikó István , Notton David , Deans Andrew 
Published: January 2018

A new species, Dendrocerus scutellaris Trietsch & Mikó (Hymenoptera: Megaspilidae), is described here from male and female specimens captured in Costa Rica. This species is the only known ceraphronoid wasp with a straight mandibular surface and raised dorsal projections on the scutellum, called the mesoscutellar comb. It is hypothesised that the function of the mesoscutellar comb is to aid the emergence of the adult from the host, especially since the mandibles lack a pointed surface to tear open the pupal case. The authors also provide phenotypic data in a semantic form to facilitate data integration and accessibility across taxa and provide an updated phenotype bank of morphological characters for megaspilid taxonomic treatments. In updating this phenotype bank, the authors continue to make taxonomic data accessible to future systematic efforts focusing on Ceraphronoidea.

Pilot Study of Educational Gaming to Improve Adherence to an End-Tidal Carbon Dioxide Monitoring Protocol
Authors: Jansen Taylore D. , Stutzman Sonja , Yu Christine , Parry David , Olson DaiWai M. 
Published: January 2018

Background:
End-tidal carbon dioxide (ETCO2) monitoring is an important part of patient care. Understanding and interpreting ETCO2 wavelengths can be a challenge. This pilot study explored the efficacy of a novel approach to educating clinicians on ETCO2 monitoring via game theory.

Method:
A video game application for ETCO2 monitoring was developed. Clinicians were encouraged to play the game over a 3-month period. Compliance with the ETCO2 protocol was compared in a random selection of patients admitted before, during, and after the intervention.

Results:

Thirty-eight clinicians completed the preand posttest, with a significant difference in test scores (
p
= .03). The intervention was associated with higher adherence to the ETCO2 protocol before and after the intervention (
p
< .05).

Conclusion:
The availability of new technologies has created opportunities to develop new approaches to educate clinicians. This study showed that the use of a game improved adherence to the ETCO2 protocol.

Evaluation of a Clinical Policy Learning Activity
Authors: Yimmee Suchawadee , Fitzwater Julie , O'Donovan Patrice A. , Tong Vivian 
Published: January 2018

Background:
Student groups compare evidence-based practice (EBP) to actual practice defined by hospital policies in their clinical rotation sites. This article describes a pilot study evaluating this clinical learning activity.

Method:
Student and faculty surveys were developed and piloted. Purposive sampling with the surveys produced qualitative data and basic statistics to evaluate the learning activity.

Results:
This study suggests that students' satisfaction with the clinical learning activity was generally positive. Three themes emerged, including Relevance to Clinical Practice, Course Outcomes Met, and Reinforcement of Evidence-Based Practice. Faculty surveys showed this learning activity was a useful tool for students to learn and utilize EBP.

Conclusion:

The learning activity is an effective learning and teaching strategy. Collaboration among nursing students, faculty, librarian, and nurses enhanced students' understanding of evidence related to policies in nursing practice and create a meaningful experience. Further work will focus on validation of the surveys. [

Which panel data estimator should I use?: A corrigendum and extension
Authors: Moundigbaye Mantobaye , Rea William S. , Reed W. Robert 
Published: January 2018

Abstract
This study uses Monte Carlo experiments to produce new evidence on the performance of a wide range of panel data estimators. It focuses on estimators that are readily available in statistical software packages such as Stata and Eviews, and for which the number of cross-sectional units (N) and time periods (T) are small to moderate in size. The goal is to develop practical guidelines that will enable researchers to select the best estimator for a given type of data. It extends a previous study on the subject (Reed and Ye, Which panel data estimator should I use? 2011), and modifies their recommendations. The new recommendations provide a (virtually) complete decision tree: When it comes to choosing an estimator for efficiency, it uses the size of the panel dataset (N and T) to guide the researcher to the best estimator. When it comes to choosing an estimator for hypothesis testing, it identifies one estimator as superior across all the data scenarios included in the study. An unusual finding is that researchers should use different estimators for estimating coefficients and testing hypotheses. The authors present evidence that bootstrapping allows one to use the same estimator for both.
Of Public Space: My Island Home
Authors: Crofts Penny 
Published: January 2018

Welcome to the second volume of the refereed journal, Public Space: the Journal of Law and Social Justice.

The second volume of Public Space offers a meditation on the theme My Island Home. The theme was inspired, in part, by Neil Murray’s song My Island Home. Murray said that he had been living in the deserts of Central Australia for some time, estranged from the fresh water country of his youth. He wrote the song after spending a week camping at Galiwinku in Arnhem Land, living like a king on bush tucker, and then leaving to travel
to Sydney during the winter. The song expressed his intense longing to be in a boat on a tropical sea.
Transport of regional pollutants through a remote trans-Himalayan valley in Nepal
Authors: Dhungel Shradda , Kathayat Bhogendra , Mahata Khadak , Panday Arnico 
Published: January 2018

Abstract. Anthropogenic emissions from the combustion of fossil fuels and biomass in Asia have increased in recent years. High concentrations of reactive trace gases and light-absorbing and light-scattering particles from these sources form persistent haze layers, also known as atmospheric brown clouds, over the Indo–Gangetic plains (IGP) from December through early June. Models and satellite imagery suggest that strong wind systems within deep Himalayan valleys are major pathways by which pollutants from the IGP are transported to the higher Himalaya. However, observational evidence of the transport of polluted air masses through Himalayan valleys has been lacking to date. To evaluate this pathway, we measured black carbon (BC), ozone (O3), and associated meteorological conditions within the Kali Gandaki Valley (KGV), Nepal, from January 2013 to July 2015. BC and O3 varied over both diurnal and seasonal cycles. Relative to nighttime, mean BC and O3 concentrations within the valley were higher during daytime when the up-valley flow (average velocity of 17 m s−1) dominated. BC and O3 concentrations also varied seasonally with minima during the monsoon season (July to September). Concentrations of both species subsequently increased post-monsoon and peaked during March to May. Average concentrations for O3 during the seasonally representative months of April, August, and November were 41.7, 24.5, and 29.4 ppbv, respectively, while the corresponding BC concentrations were 1.17, 0.24, and 1.01 µg m−3, respectively. Up-valley fluxes of BC were significantly greater than down-valley fluxes during all seasons. In addition, frequent episodes of BC concentrations 2–3 times higher than average persisted from several days to a week during non-monsoon months. Our observations of increases in BC concentration and fluxes in the valley, particularly during pre-monsoon, provide evidence that trans-Himalayan valleys are important conduits for transport of pollutants from the IGP to the higher Himalaya.
Criteria for the optimal selection of remote sensing optical images to map event landslides

Published: January 2018

Abstract. Landslides leave discernible signs on the land surface, most of which can be
captured in remote sensing images. Trained geomorphologists analyse remote
sensing images and map landslides through heuristic interpretation of
photographic and morphological characteristics. Despite a wide use of remote
sensing images for landslide mapping, no attempt to evaluate how the image
characteristics influence landslide identification and mapping exists. This
paper presents an experiment to determine the effects of optical image
characteristics, such as spatial resolution, spectral content and image type
(monoscopic or stereoscopic), on landslide mapping. We considered eight maps
of the same landslide in central Italy: (i) six maps obtained through expert
heuristic visual interpretation of remote sensing images, (ii) one map
through a reconnaissance field survey, and (iii) one map obtained through a
real-time kinematic (RTK) differential global positioning system (dGPS)
survey, which served as a benchmark. The eight maps were compared pairwise
and to a benchmark. The mismatch between each map pair was quantified by
the error index, E. Results show that the map closest to the benchmark
delineation of the landslide was obtained using the higher resolution image,
where the landslide signature was primarily photographical (in the landslide
source and transport area). Conversely, where the landslide signature was
mainly morphological (in the landslide deposit) the best mapping result was
obtained using the stereoscopic images. Albeit conducted on a single
landslide, the experiment results are general, and provide useful
information to decide on the optimal imagery for the production of event,
seasonal and multi-temporal landslide inventory maps.
Structural Racism and the Will to Act
Authors: Lopez Bunyasi Tehama 
Published: January 2018

In only a few short years, Black Lives Matter has shaped mainstream discourse of racial inequality so as to emphasize the disparate ways our society tends to value certain lives and contributions over others. In this essay, I describe how today's Black liberation movement inspired me to revise a graduate course on race and conflict that directs students to think about how contemporary institutions and social practices determine the value of life at the color line. In the epilogue, I ponder another round of revisions given the outcome of the 2016 presidential election.

Les déterminants de l’urbanisation des communautés innues de la Côte-Nord
Authors: Déborbe Matthieu , Vachon Geneviève 
Published: January 2018

Cet article aborde les liens entre l’histoire du développement de Uashat, Maliotenam, Pessamit et Nutashkuan, et la morphologie de leur territoire de réserve ou Innu Assi. Au moyen de sources historiques, cartographiques et littéraires, l’étude identifie et croise les éléments et acteurs ayant influencé ce développement. Combinée à la caractérisation évolutive des formes urbaines (ou morphogenèse), cette approche révèle des coïncidences chronologiques à l’intérieur de trois périodes : 1) la création des premières réserves, avant la Seconde Guerre mondiale ; 2) l’intensification de la sédentarisation et de la croissance urbaine, dans l’après-guerre ; et 3) la période contemporaine de décentralisation, de désengagement de l’État et de dévolution politique et administrative aux communautés. Les résultats mettent en évidence une double rupture au sein de l’Innu Assi contemporain par le biais d’un processus de sédentarisation forcée, et par l’établissement d’un milieu de vie pensé et construit par un autre peuple que celui qui l’habite.
A Planar UWB Antenna with Dual Band Rejection Capability Using Double Rotated ESRRs
Authors: Elkorany A. S. , Ahmed G. T. , Saleeb D. A. 
Published: January 2018

In this paper, CPW-Fed ultra wideband (UWB) planar monopole antenna (PMA) loaded by double elliptical split ring resonators (ESRRs) for double band-notch characteristics is introduced and examined. Two different ESRRs with different dimensions are printed in the antenna backside to notch two different frequencies. The ESRRs are also rotated and the corresponding return loss effect is examined. Different notch frequencies can be obtained by varying the ESRRs, dimensions. Two single SRRs are used to notch two frequencies instead of using dual SRR pairs. Two notch frequencies at 5.2 GHz and 6.9 GHz has been obtained to notch WLAN and C-band wireless applications, respectively. A directive radiation pattern in E-plane and omnidirectional radiation patterns in the H-plane could be observed. Also the gain is suppressed in the notch frequencies. The group delay is nearly stable in the UWB frequency range, except at the notch frequencies, which is distorted sharply. So, the proposed antenna is a good candidate for the modern UWB systems. Finite element method FEM and finite integration technique FIT are used to simulate the proposed structures through the usage of Ansys HFSS and CST MWS. Very good agreement between both results has been obtained.
