Water demand predictions for megacities: system dynamics modeling and implications
Authors: Qin Huanhuan , Cai Ximing , Zheng Chunmiao 
Published: November 2017

Abstract
Sustaining the water supply in megacities is an enormous challenge. To address this challenge, it is especially important to predict water demand changes in megacities. This paper presents a system dynamics model to predict the future water demands of different sectors considering multiple factors, including population, structure of the economy, and water supply and use technologies. Compared with traditional methods such as the time series method and structure analysis method, the proposed model takes into account the interconnections, non-linear relationships and feedbacks between the various factors in a systems context. The model is applied to Beijing, a megacity with a population over 20 million and very limited water availability. It is found that the total water demand is likely to increase by at least 36.1% (up to 62.5%) by 2030 compared with that in 2011, and the water deficits vary from −0.36 × 109 to 1.80 × 109m3 in 2030. In addition, scenarios are designed to account for impacts associated with economic development, climate change and inter-basin water transfers. It is shown that climate change may have a large impact on the water supply reliability in Beijing. The water shortage problems can be alleviated via inter-basin water transfers.

Published: November 2017

ABSTRACT: This article assesses the surface water quality of the Strîmtori‐Firiza reservoir by analyzing 14 physicochemical parameters among 9 metals in 18 sampling points. A series of possible reservoir pollutants were identified, depending on the nature of the pollutants and their loading. The novelty of the paper consists in the broad spectrum of investigations that includes spatial distribution cluster analysis and mathematical modeling. This article presents an innovative method of assessing the distributions of the metal loads as maps of metal distribution that are in accordance with the developed mathematical models that aim to present the pollutant distribution and the degree of correlation between the physicochemical indicators. The clusters were generated using Ward's and Nearest Neighbor methods that are less used in the studies concerning the analysis of water quality. Measures for maintaining the quality of the water reservoir are proposed considering the importance of the reservoir as source for drinking/industrial water.

OBJECTIVE
Cardiovascular and renal complications contribute to higher mortality in patients with diabetes. We assessed novel and conventional predictors of mortality in African American–Diabetes Heart Study (AA-DHS) participants.

RESEARCH DESIGN AND METHODS
Associations between mortality and subclinical atherosclerosis, urine albumin–to–creatinine ratio (UACR), estimated glomerular filtration rate (eGFR), plasma fibroblast growth factor 23 (FGF23) concentration, African ancestry proportion, and apolipoprotein L1 genotypes (APOL1) were assessed in 513 African Americans with type 2 diabetes; analyses were performed using Cox proportional hazards models.

RESULTS
At baseline, participants were 55.6% female with median (25th, 75th percentile) age 55 years (49.0, 62.0), diabetes duration 8 years (5.0, 13.0), glycosylated hemoglobin 60.7 mmol/mol (48.6, 76.0), eGFR 91.3 mL/min/1.73 m2 (76.4, 111.3), UACR 12.5 mg/mmol (4.2, 51.2), and coronary artery calcium 28.5 mg Ca2+ (1.0, 348.6); 11.5% had two APOL1 renal-risk variants. After 6.6-year follow-up (5.8, 7.5), 54 deaths were recorded. Higher levels of coronary artery calcified plaque, carotid artery calcified plaque, albuminuria, and FGF23 were associated with higher mortality after adjustment for age, sex, and African ancestry proportion. A penalized Cox regression that included all covariates and predictors associated with mortality identified male sex (hazard ratio [HR] 4.17 [95% CI 1.96–9.09]), higher FGF23 (HR 2.10 [95% CI 1.59–2.78]), and absence of APOL1 renal-risk genotypes (HR 0.07 [95% CI 0.01–0.69]) as the strongest predictors of mortality.

CONCLUSIONS
Accounting for conventional risk factors, higher FGF23 concentrations and APOL1 non–renal-risk genotypes associated with higher mortality in African Americans with diabetes. These data add to growing evidence supporting FGF23 association with mortality; mechanisms whereby these novel predictors impact survival remain to be determined.

Lý thuyết hệ thống xã hội là một trong các lý thuyết quan trọng của xã hội học. Khả năng ứng dung nghiên cứu của nó là rất lớn. Thuyết hệ thống nhấn mạnh vào chức năng cân bằng, ổn định, trật tự của xã hội; nó cũng đồng thời đòi hỏi mọi thành viên của xã hội phải phát huy tính chủ động của bản thân trong việc thực hiện các vai trò của mình song cũng đồng thời phải biết tuân thủ những đòi hỏi chung của cả hệ thống hệ thống. Thuyết hệ thống cũng nhấn mạnh vào việc mỗi cá nhân phải thực hiện không chỉ một vai trò mà là một tập hợp các vai trò (cả theo chiều “ngang” và cả theo chiều “dọc”). Một trong những nghiên cứu ứng dụng lý thuyết có ý nghĩa là việc vận dụng lý thuyết tiếp cận hệ thống vào việc hoàn thiện cơ chế Đảng lãnh đạo nhà nước quản lý nhân dân làm chủ. Đó là việc coi xã hội là một hệ thống lớn; trong đó bao gồm nhiều hệ thống con. Mỗi hệ thống con có những chức năng khác nhau song đồng thời lại có cùng một chức năng chung của hệ thống.

AbstractSMEs need information systems that are reliable and competent entrepreneurial personality that will have an impact on managerial performance. Information reliable accounting system according Chenhall and Morris (1986) is one that has the characteristics of broad scope, timeliness, aggregation and integration. Information management accounting system that is broad scope is information that attention focus, quantification, and time horizon. Timeliness dimension has two sub dimensions, namely the frequency of reporting and speed of reporting. Dimensions aggregate is a summary of information by function, time periods, and the decision model. Integrated information reflects the lack of coordination between segments of one and the other subunits within the organization. This research is quantitative. This study uses analysis of causal relationships, that is how one variable affects changes in other variables. To analyze the data, this study uses analysis of Structural Equation Modeling (SEM) approach Partial Least Square (PLS).In data processing using software Warp PLS. The results showed that the Accounting Information Systems Management is broadscope, timeliness, integrated, and the aggregate effect on Managerial Performance is measured using an instrument of self-rating which is reflected in four indicators, namely increased revenue, cost savings, improved customer satisfaction and increased asset utilization. This shows that although SMEs are the type of business that is not great, but still requires a wide range of information, timely, integrated and comprehensive that can assist managers in making informed decisions that impact the increase managerial performance related to efficiency-related costs but still consider satisfaction customers thus increasing the income of the SMEs in environmental conditions of uncertainty.

Ester-Based Pyridinium Gemini Surfactants as Novel Inhibitors for Mild Steel Corrosion in 1 M HCl Solution
Authors: Mobin Mohammad , Aslam Ruby 
Published: November 2017

AbstractThe corrosion inhibition ability of ester based pyridinium Gemini surfactants (GS) with different hydrophobic character (14-Py and 16-Py) towards mild steel (MS) in 1 M HCl solution was investigated at various concentrations and temperatures (303–333 K). Potentiodynamic polarization, electrochemical impedance spectroscopy, weight loss, surface analysis (SEM/EDAX and AFM) and FT-IR were combined to investigate the corrosion inhibition behaviour of the surfactants. 14-Py and 16-Py were found to be efficient, mixed type inhibitors. The inhibition efficiencies increased with increasing concentration, hydrophobicity and solution temperature. The existence of a protective film of the adsorbed inhibitors on the MS surface was confirmed by SEM/EDX/AFM.

Published: November 2017

AbstractA novel double-hydrophilic copolymer (acrylic acid-isoprenyl polyethoxy carboxylate, AA-TPEL) is synthesized and the structural properties are identified by FT-IR, 1HNMR and GPC analyses. The inhibitory behavior of the copolymer is determined by using a static scale inhibition method. It is shown that AA-TPEL exhibits an excellent ability to control the formation of CaCO3 scale with an inhibition efficiency of 88.67 % at the 8 mg L–1, and it still maintains a superior efficiency even at increasing solution temperature, pH, and Ca2+ concentration. Weight loss test, potentiodynamic polarization and electrochemical impedance spectroscopy are applied to investigate the inhibition efficiency on mild steel corrosion. All measurements show that, AA-TPEL acts as an efficient corrosion inhibitor and also displays a superior ability to prevent the corrosion of mild steel with approximately 83.21 % inhibition efficiency at the low level of 10 mg L–1. Scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) are used to characterize the surface morphology of CaCO3 and steel.
Gamma-Ray Flux Distribution and Nonlinear Behavior of Four LAT Bright AGNs

Published: November 2017

Abstract
We present a statistical characterization of the γ-ray emission from the four Fermi-LAT sources: FR I radio galaxy NGC 1275, BL Lac Mrk 421, FSRQs B2 1520+31, and PKS 1510-089 detected almost continuously over a time integration of three days between 2008 August and 2015 October. The observed flux variation is large, spanning

orders of magnitude between the extremes, except for Mrk 421. We compute the flux distributions and compare with Gaussian and lognormal ones. We find that the three blazars have distributions consistent with a lognormal, suggesting that the variability is of a nonlinear, multiplicative nature. This is further supported by the computation of the flux-rms relation, which is observed to be linear for the three blazars. However, for NGC 1275, the distribution does not seem to be represented either by a lognormal or a Gaussian, while its flux-rms relation is still found to be linear. We also compute the power spectra, which suggest the presence of a break, but are consistent with typical scale-free power-law shot noise. The results are broadly consistent with the statistical properties of the magnetic reconnection powered minijets-in-a-jet model. We discuss other possible scenarios and implications of these observations on jet processes and connections with the central engine.
Effects of Solar Activity on the Local Interstellar Magnetic Field Observed by Voyager 1 and IBEX
Authors: Schwadron N. A. , McComas D. J. 
Published: November 2017

Abstract

Interstellar Boundary Explorer (IBEX) observations have shown enhanced energetic neutral atom emission from a narrow, circular ribbon likely centered on the direction of the magnetic field in the local interstellar medium (LISM). IBEX observations are compared to Voyager 1's direct observations of the magnetic field in the LISM, which reveals structured changes that are shown here to be driven by pressure fluctuations transmitted across the heliopause boundary separating the LISM from the shocked solar wind beyond the termination shock. The changes in the local interstellar magnetic field observed by Voyager 1 occurred in 2015 and 2016, when the most powerful coronal mass ejections released from the Sun over the last 11-year solar cycle arrived in the outer heliosphere. These events propagated over more than two years through the solar system, ultimately pounding the heliopause and causing transient deviations of the magnetic fields detected by Voyager 1 in the LISM. Thus, we identify the response in pressure variations at Voyager 1 in the LISM with the activity of major solar events several years earlier, during the most active period of the last solar maximum.
The Effect of Turbulence on Nebular Emission Line Ratios

Abstract
Motivated by the observed differences in the nebular emission of nearby and high redshift galaxies, we carry out a set of direct numerical simulations of turbulent astrophysical media exposed to a UV background. The simulations assume a metallicity of

and explicitly track ionization, recombination, charge transfer, and ion-by-ion radiative cooling for several astrophysically important elements. Each model is run to a global steady state that depends on the ionization parameter U, and the one-dimensional turbulent velocity dispersion,

, and the turbulent driving scale. We carry out a suite of models with a T = 42,000 K blackbody spectrum, n

e
= 100 cm−3, and

ranging between 0.7 and 42 km

corresponding to turbulent Mach numbers varying between 0.05 and 2.6. We report our results as several nebular diagnostic diagrams and compare them to observations of star-forming galaxies at a redshift of

, whose higher surface densities may also lead to more turbulent interstellar media. We find that subsonic, transsonic turbulence, and turbulence driven on scales of 1 parsec or greater, have little or no effect on the line ratios. Supersonic, small-scale turbulence, on the other hand, generally increases the computed line emission. In fact with a driving scale

pc, a moderate amount of turbulence,

= 21–28 km

can reproduce many of the differences between high and low redshift observations without resorting to harder spectral shapes.

Nos enfants auront d’autant plus de chances de s’engager dans une bonne utilisation des outils numériques que nous introduirons ceux-ci dans leur vie au bon moment et de la bonne façon. C’est le but des balises 3-6-9-12 d’y contribuer en fondant une indispensable diététique des écrans. Elles s’appuient sur quatre recommandations importantes à tout âge : limiter les temps d’écran, choisir avec les enfants des programmes de qualité, parler avec eux de ce qu’ils voient et font avec les écrans, et encourager leurs activités de création dès le plus jeune âge. Le combat pour les bébés d’aujourd’hui est un combat pour la société de demain.
L’écran est-il bon ou mauvais pour le jeune enfant ?

Published: November 2017

Le taux d’exposition des enfants à l’écran augmente et devient de plus en plus précoce. Aujourd’hui, selon plusieurs enquêtes américaines, 90% des enfants de moins de deux ans regardent l’écran pendant en moyenne deux heures par jour, et ce malgré les recommandations contraires de l’Académie Américaine de Pédiatrie et du Ministère de la Santé Français. L’objectif de cette revue est double : (1) comprendre les corrélats et les facteurs démographiques déterminant l’exposition à la télévision et (2) étudier les effets de la télévision sur le développement cognitif du jeune enfant. La littérature scientifique montre que l’effet de l’écran dépend moins de la durée de visionnage hebdomadaire que de l’âge et des contextes dans lesquels les enfants regardent l’écran (accompagnés ou non) ainsi que des contenus regardés (éducatifs ou non). Prises dans leur ensemble, les études montrent que l’exposition aux écrans a un impact négatif sur le développement, particulièrement quand l’exposition concerne des enfants âgés de moins de trois ans.
