Abstract
This paper presents our progress in developing, testing, and implementing a Ubiquitous Sensing Network (USN) for real-time monitoring of methane emissions. This newsensor technology supports environmental management of industrial sites through a decision support system. Upon detection of specific inputs, data is processed before passing it on for appropriate actions (Data→Insight→Actions). The technology integrates wireless methane sensor nodes, weather sensors, edge-based devices and is powered by a self- contained solar-battery powered system. A cloud-based data analytics IoT solution is included for handling continuous sensor monitoring. A sample of results from an in-house simulated well site are presented within the body of this paper. Preliminary predictions seem to correlate well with the true emission rate as indicated by the proximity of the predictions to the forty-five-degree line. Running more tests should allow us to further estimate the error distribution as well as the prediction interval width and the overall emission rate prediction trend. The initial results demonstrate that the developed technology can quantify the emission rate (scfh) within 1% and 45% error, and a localization error within six feet to fifty feet given a test area of 10,000 square feet. This integrated solution is being ruggedized and the analytics are being optimized for continuous monitoring of methane emissions at customer sites for safety, product loss prevention, and regulatory compliance.
Tensor Analysis of the Relative Permeability in Naturally Fractured Reservoirs
Authors: Sedaghat Mohammad H. , Azizmohammadi Siroos , Matthäi Stephan K. 
Published: September 2019

Summary
Fluid evidence shows that prediction of water breakthrough and oil recovery from fractured reservoirs cannot be performed accurately without upscaled relative permeability functions. Relative permeability is commonly assumed to be a scalar quantity, although the justification of that—specifically for naturally fractured reservoirs (NFRs)—is rarely attempted. In this study, we investigate the validity of this scalar-quantity assumption and how it affects fracture/matrix equivalent relative permeabilities, kri(Sw), achieved by a numerical simulation of unsteady-state waterflooding of discrete-fracture/matrix models (DFMs).
Numerical determination of relative permeability requires a realistic model, a spatially adaptive simulation approach, and a sophisticated analysis procedure. To fulfil these requirements, we apply the discrete-fracture/matrix modeling to well-characterized outcrop analogs at the hectometer to kilometer scale. These models are parameterized with aperture and capillary entry pressure data, taking into account variations from fracture segment to segment, trying to emulate in-situ conditions. The finite-element-centered finite-volume method is used to simulate two-phase flow in the fractured rock, while also considering a range of wettability conditions from water-wet to oil-wet.
Our results indicate that the fracture/matrix equivalent relative permeability is a weakly anisotropic property. The tensors are not necessarily symmetric, and the absolute-permeability tensor is the most influential factor, determining the level of anisotropy of kri. The anisotropy ratio (AR) changes with saturation, is influenced by the fracture/matrix-interface wetted area (Awf), and differs for each phase. In addition, the diagonal terms of the equivalent relative permeability tensor (krii), determined using our novel approach, can be different from those obtained using the assumption that kri is scalar. The magnitude of the difference is controlled by the absolute permeability, wettability, flow rate, and orientation of the fractures in the model. It is worth mentioning that the type and direction of imbibition can be determined by off-diagonal terms of the kri tensor. Furthermore, krii largely depends on the direction of the waterflood along the i-axis.
A Unified Gas/Liquid Drift-Flux Model for All Wellbore Inclinations
Authors: Tang Hewei , Bailey William J. , Stone Terry , Killough John 
Published: September 2019

Summary
Implementation of a drift–flux (DF) multiphase–flow model within a fully coupled wellbore/reservoir simulator is nontrivial because it must adhere to a number of strict requirements to ensure numerical robustness and convergence. The existing DF model that meets these requirements is only fully posed from 2° (from the horizontal) to upward vertical. Our work attempts to extend the current DF model such that it is numerically robust, accurate, and applicable to all well inclinations. To gauge accuracy, model parameterization used 5,805 experimental data points from a well–established data set, along with a second data set comprising 13,440 data points extracted from the OLGA–S library (Schlumberger 2017b). Forecast accuracy of the proposed model is compared with that of two state–of–the–art DF models (applicable to all inclinations but unsuited for coupled simulation), and it exhibits equivalent or better performance. More significantly, the model is shown to be numerically smooth, continuous, and stable for cocurrent flow when implemented in a fully implicit and coupled wellbore/reservoir simulator.
Meconium contaminated amniotic fluid leads to intestinal wall thickness and affects the functional outcome of abdominal wall defects
Authors: Kapapa Melanie , Rieg Teresa , Serra Alexandre 
Published: September 2019

Abstract
Background: We analysed abdominal wall defect patients over an 11-year period, aiming to assess the influence of meconium-contaminated amniotic fluid . Meconium-contaminated amniotic fluid leading to intestinal wall thickness and impairs surgical and functional outcome. Methods: A retro- and prospective, observational case- control design was used to compare gastroschisis (n=36) and omphalocele (n=18) children. Physical data, color of amniotic fluid, pre- and perinatal problems, operative complications and surgical technique, postoperative complications, duration of ICU stay, mechanical ventilation, parenteral nutrition, begin of oral feeding and total hospital stay were collected. Data was analyzed with descriptive methods, t-test and non-parametric tests such as Wilcoxon and Kruskal-Wallis were performed in addition to ANOVA, including post-hoc testing accepting a confidence interval of 95% (p<0.05) by using IBM SPSS software, version 23 (IBM, Illinois, USA). Results: Rate of meconium-contaminated amniotic fluid is significantly higher in GS compared to OC, delivery problems are also significantly higher, this yields in significantly more bowel loops anomalies and problems during surgery but had no significant influence on primary abdominal wall closures rate. The post-surgical outcome of OC was significantly better compared to GS. Within the GS, those with swollen intestines had significantly longer ICU stays due to extended mechanical ventilation, parenteral nutrition and delayed initiation of oral feeding. Same results were found for secondary closures compared to primary abdominal wall closures in GS group. Conclusions: Worsen functional short-term outcome of GS children was directly addicted to meconium contamination of amniotic fluid due to swollen intestines and because of this more post-surgical problem including significantly extended hospital stay were observed.

Abstract
Background The purpose of this study was to evaluate the clinical effect of antibiotic cement-coated locking plate as temporary internal fixation for the treatment of long bone infection in lower extremities . Methods Retrospective analysis the clinical data of 183 patients with lower extremities long bone infection admitted to our hospital from January 2013 to December 2017. All patients were treated with locking plate internal fixation after primary debridement. Antibiotic cement was used to fill the bone defect and wrap the plate. After infection control, bone grafting to reconstruct the bone defect. Results There were 81 cases of femur, 100 cases of tibia and 2 cases of fibula, after the first stage, 16(8.7%) patients had recurrence of infection after the first stage which have to debridement again. 4 tibial infecton patients had poor wound healing, 2 femoral patients had fixation failure, and 1 patient had femoral fracture due to fall down. After a mean time of 32.0 months (range 12 to 66) follow up, the recurrence rate of infection was 14.2% (26/183). Among them, eighteen patients underwent bone grafting after re-debridement, 6 patients received permanent placement of antibiotic bone cement after debridement, and 2 patients refused further treatment and chose amputation. Bone healing was achieved in 175(95.9%) patients in the last follow-up, and the average time of bone union was 5.4 months (range 4 to 12 months). Conclusions Temporary internal fixation with antibiotic cement coated locking plate has good clinical effect in the treatment of lower extremities long bone infection. It does not increase the difficulty of bone infection control. Pay attention to possible difficulty of skin coverage when applied in calves. Key words: Antibiotic cement coated locking plate, Bone infection, Internal fixation
Health Service Utilization and Out-Of-Pocket Health Expenditure Among Insured and Uninsured: A Comparative Study in Baglung District, Nepal
Authors: Bhatt Laxman Datt , Dhami Shankar Singh 
Published: September 2019

Abstract
Background

Nepal's Interim Constitution of 2007 addresses health as a fundamental right, stating that every citizen has the right to basic health services free of cost. Government of Nepal formed a Social Health Security Development Committee as a legal framework to start implementing a social health security scheme after the National Health Insurance Policy came out in 2013. The program has aimed to increase the access of health services to the poor and the marginalized, and people in hard to reach areas of the country, though challenges remain with financing. Several aspects should be considered in design, learning from earlier community-based health insurance schemes that suffered from low enrollment and retention of members as well as from a pro-rich bias.Method

A community based cross-sectional comparative study was conducted in Baglung district of Nepal to find out and compare the health service utilization and direct out-of-pocket health care expenditure among the 225 insured and 225 uninsured households under the national health insurance program of Nepal. Insured households were randomly chosen from study area and uninsured households were selected by using neighborhood method.Result

The study focused that insurance status was strongly associated with heath service utilization with odds ratio 1.774 (95% CI = 1.127-2.791, P = 0.013). The study also depicts that insurance status was major determinants of out of pocket health expenditure. The median out-of-pocket health expenditure among insured households Nepalese Rupees 200 while among uninsured was 1225, which was statistically significant (p = <0.001 MW-U test). Among uninsured group, non-dalit were 2.846 times more likely to utilize health services compared to the dalit (p = 0.003) but it was not significant (p = 0.47) among insured group.Conclusion

Nepal’s Health Insurance Board is responsible for purchasing the quality health care service and make available at possible nearest point of its member. Our study reveals that Occupation, perceived health status, wealth status played significant role with health service utilization among uninsured group while it was not significant among insured group. Among both insured and uninsured group none of the study variables were found significant with out-of-pocket health expenditure.
Microarray expression profile and bioinformatic analyses of circular RNA in human esophageal carcinoma
Authors: Chen Xiaohua , Wang Liping , Cai Sina , Zhang Xiaona , Li Wenhui , Liang Henglun 
Published: September 2019

Abstract
Background : Recent studies indicate that noncoding circular RNAs (circRNAs) are involved in the development of esophageal carcinoma. This study aimed to identify circRNAs that are differentially expressed in esophageal carcinoma (EC), which may provide potential biomarkers and therapeutic targets for EC and improve the understanding of its tumorigenesis mechanism. Methods : Ten samples of esophageal carcinoma tissues were sent for circRNA microarray detection. Then the data was subjected to bioimformatic analysis (including circRNA-microRNA (miRNA) coexpression network, Spearman’s correlation test and cancer-related circRNA-miRNA axis analyses). The gene expressions of key circRNAs were detected by real-time- PCR. Results: A total of 102 upregulated and 67 significantly downregulated circRNAs were identified in EC tumors compared to adjacent normal tissue by microarray analysis. One upregulated circRNA (hsa_circRNA_401955) showed the most correlation and was thus regarded as the hub gene by the Spearman correlation test. KEGG pathway enrichment analyses showed that four primary pathways (mRNA surveillance, cytoskeletn actin regulation, spliceosome and the NOD-like receptor signaling pathway) were predicted in the five connected miRNA response elements (MREs) of hub circRNA’ s. Furthermore, cancer-related circRNA-miRNA axis analyses revealed that hsa_circRNA_100375 and its four connected MREs contributed to a cancer-related pathway. The expressions of hsa_circRNA_100375 and hsa_circRNA_401955 were increased significantly in the tumor tissues according to q-PCR. Conclusion: CircRNA dysregulation was involved in the tumorigenesis of EC. The key circRNAs of hsa_circRNA_401955 and hsa_circRNA_100375 may serve as potential biomarkers and therapeutic targets for EC.
Magmatic carbon outgassing and uptake of CO2 by alkaline waters
Authors: Edmonds Marie , Tutolo Benjamin , Iacovino Kayla , Moussallam Yves 
Published: September 2019

AbstractMuch of Earth's carbon resides in the “deep” realms of our planet: sediments, crust, mantle, and core. The interaction of these deep reservoirs of carbon with the surface reservoir (atmosphere and oceans) leads to a habitable surface environment, with an equitable atmospheric composition and comfortable range in temperature that together have allowed life to proliferate. The Earth in Five Reactions project (part of the Deep Carbon Observatory program) identified the most important carbon-bearing reactions of our planet, defined as those which perhaps make our planet unique among those in our Solar System, to highlight and review how the deep and surface carbon cycles connect. Here we review the important reactions that control the concentration of carbon dioxide in our atmosphere: outgassing from magmas during volcanic eruptions and during magmatic activity; and uptake of CO2 by alkaline surface waters. We describe the state of our knowledge about these reactions and their controls, the extent to which we understand the mass budgets of carbon that are mediated by these reactions, and finally, the implications of these reactions for understanding present-day climate change that is driven by anthropogenic emission of CO2.
Celestine discovered in Hawaiian basalts
Authors: Garcia Michael O. , Hellebrand Eric 
Published: September 2019

Abstract
We report here the first occurrence of celestine (SrSO4) in recent oceanic basalts. Celestine was found in moderately altered accidental volcanic blocks from Ka‘ula Island, a rejuvenated tuff cone in the northern Hawaiian Islands. This occurrence is novel not only for the presence of celestine but also for the absence of barite, the sulfate mineral most commonly found in oceanic hydrothermal deposits. Celestine was found lining vesicles and partially fillings voids within the matrix of several high Sr (2200–6400 ppm) Ka‘ula basalts. High-quality wavelength-dispersive microprobe analyses of celestine are reported here for near end-member celestine (&gt;90%). The Ka‘ula celestine deposits are compositionally heterogeneous with large variations in Ba content (0.9–7.5 wt%) within single mineral aggregates. The most likely source of the Sr for celestine in the Ka‘ula basalts was the host basalt, which contains ~1200 ppm. This is about 10 times higher than normally found in mid-ocean ridge basalts and 4 times greater than commonly observed in Hawaiian basalts. Hydrothermal alteration by S-bearing fluids related to the eruption that transported these accidentally fragments probably mobilized Sr in the blocks. These S-rich solutions later precipitated celestine during or following the eruption. We were unable to confirm the origin for the Sr via Sr isotope measures because the Ka‘ula celestine was too fine grained, friable, and widely dispersed to be concentrated for Sr isotope analyses. Future studies of basalts from active volcanoes on oceanic islands, especially for basalts with elevated Sr contents (&gt;1000 ppm), should be aware of the possible presence of celestine in moderately altered lavas.
N-doped three-dimensional carbon foam as binder-free electrode for organic pollutants removal by electro-Fenton in neutral medium
Authors: Zhao Jujiao , Quan Xie , Chen Shuo , Yu Hongtao 
Published: September 2019

Abstract
Electro-Fenton in neutral medium has attracted more and more attention since it can relieve the costs of H2O2 storage and pH adjustment, which are the major disadvantages limiting the practical applications of Fenton reaction. The electrode with good performance for electrochemical H2O2 production from O2 in neutral medium is of great importance in electro-Fenton. Herein, the N-doped three-dimensional carbon foam (NCF) electrode was obtained by using melamine foam as precursor. The nitrogen functional groups and graphitization degree could be tailored by adjusting the carbonization temperature. NCF1000, the sample carbonized at 1,000 °C, presents the H2O2 selectivity of 81.9%, which is the highest among those of other NCFs. The H2O2 concentration in neutral medium on NCF1000 achieved 0.87 mmol L−1 at −0.6 V, which is 1.8, 2 and 2.6 times as much as those on graphite, carbon cloth and carbon felt. Using as cathode in electro-Fenton, NCF1000 exhibits the kinetic rate of 0.062 min−1 for phenol degradation, which is 4.1 times larger than that on graphite electrode. As well, the performance of NCF1000 shows no visible attenuation after ten times phenol removal experiments, demonstrating its good reusability. These results indicate the potential of NCF as a promising alternative for commercial carbon-based electrode in electro-Fenton.
Road deposited sediment: implications for the performance of filter drains servicing strategic trunk roads
Authors: Mitchell Ged , Oduyemi Kehinde , Akunna Joseph 
Published: September 2019

AbstractThis study investigates the contribution of road deposited sediment (RDS) to clogging and the operational lifecycle of highway filter drains (HFDs). RDS samples were collected from nine Scottish trunk roads and fractionated into grain size classes to determine their particle size distributions (PSDs). Results show that RDS PSDs, and the percentage of each grain size fraction, are highly variable. However, despite being collected from different trunk roads, PSD trends are similar, with individual RDS particles ranging in size from &lt;63 μm to &gt;10,000 μm. Medium sand, coarse sand, fine gravel and medium gravel make up 84.1% of the total particle mass concentration, with particles &gt;1,000 μm mostly mineral or asphalt. The study also reveals that the dynamic nature of a trunk road catchment dictates that grading envelopes are essentially instantaneous values. These findings indicate that large particles from the road surface contribute to clogging and have the potential to reduce the operational lifecycle of HFDs. The study also demonstrated that assuming a single RDS PSD profile for filter drain asset management purposes is unlikely to be representative of a trunk road catchment profile.
Dose HLA-B5, 7, 8, 27, and 51 Antigens Associated to Behcet's disease? A Study in Southwestern Iran
Authors: Rajaei Elham , Jalali Mohammad T. , Pezeshki Seyed M. Sadegh , Rezaeeyan Hadi , Maniati Mahmood , Elyasi Milad , Zayeri Zeinab D. 
Published: September 2019

Background:
Behcet's disease is a potentially life threatening autoimmune disease with
recurrent ulcers and unknown pathogenesis. Gender and human leukocyte antigen-B51 seem to
have an effective role in the clinical features of the disease.

Objective:
The aim of this study is to evaluate the frequency of HLA-B5, 7, 8, 27 and 51 in behçet's
disease in southwestern Iranian patients who visited the rheumatology clinic and to find the association
between these HLA types and the disease.

Methods:
63 patients with behcet's disease participated in this study and peripheral blood samples
were collected from them. The expression of each HLA antigen was evaluated by standard lymphocytotoxicity
technique.

Results:
Compared to other studied antigens, the expression of HLA-B5 and HLA-B51 was more
prevalent among our patients. According to the results, 25% and 21% of patients were positive for
HLA-B5 and HLA-B51, respectively.

Conclusions:
HLA-B5 and HLA-B51 are dominant positive HLA antigens among behcet's disease
patients in the southwest of Iran; however, we cannot conclude that these antigens are valuable diagnostic
or prognostic biomarkers due to our study limitations. We suggest studying the association
between HLA-B antigens and inflammation severity in patients to determine the possible prognostic
value of HLA-B antigens in Iranian population in the southwest and this region needs more
studies in HLA subject among BD patients because of the frequency of BD to evaluate the value of
HLA typing in BD prognosis.
