Determination of silver in rocks and ores samples using modified voltammetric technique

Summary: Novel modified electrochemical method were used to analyze sedimentary, metamorphic, igneous, fined grained, coarse grain granite, granite with feldlaths and ferrogenous sand stone rocks along with boulangerite, stibnite, magnetite and scheelite ores for the presence of silver. Rocks and ores samples were processed through fire assay and acid digestion methods. Effect of various interfering metal ions was studied and it was observed that Hg(I) ions contributed maximum increment in the peak current of Ag(I). Differential pulse anodic stripping voltammetry (DPASV) and cyclic voltammetry (CV) were applied for the determination of silver. Glassy carbon bare and modified electrodes were used as working electrodes. Platinum and saturated calomel electrodes were applied as auxiliary and reference electrodes respectively. The modified method has high affinity, selectivity and sensitivity and can be applied for trace level determination of metal ions. The limits of detection (LDL), quantification (LOQ) and linear regression coefficient (R 2 ) were found 1. 14µg/L, 3. 2µg/L and 0.9969 respectively.
With a Little Help from My Friends: The Role of Intraoperative Fluorescent Dyes in the Surgical Management of High-Grade Gliomas

High-grade gliomas (HGGs) are the most frequent primary malignant brain tumors in adults, which lead to death within two years of diagnosis. Maximal safe resection of malignant gliomas as the first step of multimodal therapy is an accepted goal in malignant glioma surgery. Gross total resection has an important role in improving overall survival (OS) and progression-free survival (PFS), but identification of tumor borders is particularly difficult in HGGS. For this reason, imaging adjuncts, such as 5-aminolevulinic acid (5-ALA) or fluorescein sodium (FS) have been proposed as superior strategies for better defining the limits of surgical resection for HGG. 5-aminolevulinic acid (5-ALA) is implicated as precursor in the synthetic pathway of heme group. Protoporphyrin IX (PpIX) is an intermediate compound of heme metabolism, which produces fluorescence when excited by appropriate light wavelength. Malignant glioma cells have the capacity to selectively synthesize or accumulate 5-ALA-derived porphyrins after exogenous administration of 5-ALA. Fluorescein sodium (FS), on the other hand, is a fluorescent substance that is not specific to tumor cells but actually it is a marker for compromised blood-brain barrier (BBB) areas. Its effectiveness is confirmed by multicenter phase-II trial (FLUOGLIO) but lack of randomized phase III trial data. We conducted an analytic review of the literature with the objective of identifying the usefulness of 5-ALA and FS in HGG surgery in adult patients.
Glucose and lipid metabolism disorders in the chickens with dexamethasone‐induced oxidative stress

The purpose of this study was to investigate the effects of long-term treatment with dexamethasone (DEX) on the antioxidation and nutrition metabolism in broiler chickens. Broilers were placed on a high-nutrient diet for 41 days, and half were given orally DEX-supplemented water at 20 mg/L every other day from 19 to 41 days of age. DEX treatment downregulated superoxide dismutase activity as well as the mRNA expression of CuZn-superoxide dismutase and glutathione peroxidase with a decrease in GSH/GSSG ratio and an increase in malondialdehyde level in the liver of broilers. DEX treatment aggravated oxidative damage in the liver and, therefore, increased the sensitivity of broilers to ascites syndrome with higher mortality and reduced growth performance. Serum metabolomics analysis showed that DEX treatment significantly increased the levels of glucose, intermediates in protein metabolism (valine, proline, serine, threonine and urea) and lipid metabolism-related products (palmitic acid, stearic acid and cholesterol) while decreasing the levels of β-hydroxy butyric acid, succinic acid and malic acid, demonstrating that DEX treatment inhibited the Krebs cycle and the oxidation of fatty acids, and promoted the de novo synthesis of fatty acids as well as protein decomposition in the liver of broilers. Additionally, detection of metabolism-related enzymes revealed that DEX treatment inhibited glycolysis and promoted glycogen decomposition. In summary, DEX treatment resulted in oxidative stress and glucose and lipid metabolism disorders in the broilers.
Hybrid Wired-Wireless Backhaul Solutions for Heterogeneous Ultra-Dense Networks

Wireless networks are becoming extremely pervasive while trafﬁc demand is ever increasing. In order to cope with the forecast increase in trafﬁc volume for the upcoming years, as well as the number of connected devices, new technologies, practices and spectrum rearrangements are required. In this context, a key question arises: how to provide extensive backhaul connectivity and capacity for pervasive ultra dense networks? The answer is rather complex, if feasible. To shed some light into this issue we overview potential technologies, either wired or wireless, and identify technical challenges. Moreover, we evaluate an illustrative scenario of a ultra-dense network that operates with hybrid wired-wireless backhaul. We assume multiple radio access technologies at small and macro base stations (BSs), and we discuss optimal trafﬁc splitting and routing solutions for different topologies and trafﬁc proﬁles.
Activation of EP2 receptor suppresses poly(I: C) and LPS‐mediated inflammation in primary microglia and organotypic hippocampal slice cultures: Contributing role for MAPKs

Brain inflammation is a critical factor involved in neurodegeneration. Recently, the prostaglandin E2 (PGE2) downstream members were suggested to modulate neuroinflammatory responses accompanying neurodegenerative diseases. In this study, we investigated the protective effects of prostaglandin E2 receptor 2 (EP2) during TLR3 and TLR4‐driven inflammatory response using in vitro primary microglia and ex vivo organotypic hippocampal slice cultures (OHSCs). Depletion of microglia from OHSCs differentially affected TLR3 and TLR4 receptor expression. Poly(I:C) induced the production of prostaglandin E2 in OHSCs by increasing cyclooxygenase (COX‐2) and microsomal prostaglandin E synthase (mPGES)‐1. Besides, stimulation of OHSCs and microglia with Poly(I:C) upregulated EP2 receptor expression. Co‐stimulation of OHSCs and microglia with the EP2 agonist butaprost reduced inflammatory mediators induced by LPS and Poly(I:C). In Poly(I:C) challenged OHSCs, butaprost almost restored microglia ramified morphology and reduced Iba1 immunoreactivity. Importantly, microglia depletion prevented the induction of inflammatory mediators following Poly(I:C) or LPS challenge in OHSCs. Activation of EP2 receptor reversed the Poly(I:C)/LPS‐induced phosphorylation of the mitogen activated protein kinases (MAPKs) ERK, p38 MAPK and c‐Jun N‐terminal kinase (JNK) in microglia. Collectively, these data identify an anti‐inflammatory function for EP2 signaling in diverse innate immune responses, through a mechanism that involves the mitogen‐activated protein kinases pathway.
Graph-based joint mode selection and resource allocation scheme for D2D and cellular hybrid network using SCMA

Enabling device-to-device (D2D) communication in cellular network is shown to be a promising candidate in the future fifth generation (5G) wireless network. Specifically, the hybrid architecture leads to flexible and efficient resource allocation for cellular users and D2D users, thereby enhancing utilization of spectrum resources. However, if not properly handled, mutual interference will be significantly raised with the proliferation of devices, which bottlenecks the performance of the hybrid system. In this paper, joint mode selection and resource allocation is considered for a sparse code multiple access (SCMA) enabled uplink cellular network. Targeting at maximizing system sum rate, we formulate a joint optimization problem, which, however, is shown to be a mixed-integer nonlinear programming (MINLP) problem. To solve the problem, we propose a graph-based joint mode selection and resource allocation (GMR) algorithm. GMR is an interference-aware algorithm. In particular, when GMR is applied, D2D users reuse SCMA resources only when the interference level to cellular users is below a predefined threshold. Otherwise, dedicated resources are allocated to D2D users to avoid the overwhelming mutual interference. Simulation results have confirmed the efficacy of GMR in enhancing spectrum efficiency and system sum rate in the hybrid system.
Growth and Inequality: The Role of Foreign Trade and Investment

This paper addresses the influence of foreign trade and investment on inequality or, more generally, on the distribution of income, with a focus on developing countries. There has been some scholarly debate on the influence on economic growth of economic openness to the rest of the world. Since growth affects the level of poverty and the distribution of income, the tradeâ€“growth nexus is also addressed. "Distribution of income" has several quite different meanings, apart from the issue of the specific measurements that are used to describe it. Economic theory has mainly been concerned with the functional distribution of income, that is, with the returns to different identifiable factors of production and their respective shares in total income of a particular country, such as the share of labor income in national income. Popular and political discourse is more concerned with the size distribution of income, such as the fraction of national income accruing to the top ten percent, or the bottom decile, of residents of the country in question â€” and in particular on whether inequality has risen or declined. In recent years, concern with the size distribution of income has extended to the global distribution, where observations are on countries, grouped by per capita income, rather than on individuals. The two concepts of distribution are related by the ownership of the factors of production, especially land in a predominantly agrarian economy, capital in a modern economy. If ownership of land and capital were evenly distributed across a population, even significant changes in the functional distribution of income would have little impact on the size distribution of income.
Postoperative Investigations Resulting in Cost Reduction in Oncological Patients Undergoing Major Abdominal and Pelvic Surgery.

AIM Rising costs in health care are of progressively growing interest and a major factor affecting hospitalization costs is represented by postoperative complications. Complications of Major Abdominal Surgery (MAS) are associated with increased morbidity and mortality. This study estimates the costs of postoperative care associated with complications. Material and Methods: We performed a retrospective study on 254 patients admitted to the 1st General and Oncological Surgery Clinic of the Bucharest Oncology Institute who were submitted to MAS. The total hospitalization, complications and treatment costs were analysed. Results: For a patient undergoing MAS, the average costs for surgery without complications are 5,791.3 RON and reach an average of 20,806 RON after major complications. CONCLUSION The results provide insight into the costs of hospitalization for oncology patients submitted to surgical interventions. Complications occur in 20.86% of patients undergoing MAS and account for 50% of total care costs. Establishing and implementing a protocol aimed at early diagnosis and treatment of specific complications could lead to a decrease in morbidity and mortality, as well as of the costs of hospitalization.
Passivity-Based Integral Sliding Mode Active Suspension Control

Abstract A novel passivity-based sliding mode controller for active suspension system with uncertainties is presented in this paper to decrease vibration and increase robustness. Based on the characteristics of the suspension system, interconnection and damping assignment passivity- based control approach is used to construct integral sliding surface. By elaborately designing desired interconnection matrix, damping matrix and energy function, an original integral sliding surface is completed and a subcontroller is obtained to achieve sliding mode dynamic. A simplified form of subcontroller is provided when some of designable parameters are chosen properly. Combining the subcontroller with a nonlinear component, passivity-based sliding mode controller is created. Robustness analysis is given and it is proofed that the integral sliding surface is robustly stable and can be reached. Simulation under three cases circumstances validates the effect of the proposed method.
Evaluating and Optimizing IP Lookup on Many Core Processors

In recent years, there has been a growing interest in multi/many core processors as a target architecture for high performance software router. This is a clear difference from the previous trend to use dedicated network processors and hardware components. Because of its key position in routers, hardware IP lookup implementation has been intensively studied with TCAM and FPGA based architecture. However, increasing interest in software implementation has also been observed. In this paper, we evaluate the performance of software only IP lookup on a many core chip, the TILEPro64 processor. For this purpose we have implemented two widely used IP lookup algorithms, DIR-24-8-BASIC and Tree Bitmap. We evaluate the performance of these two algorithms over the TILEPro64 processor with both synthetic and real-world traces. After a detailed analysis, we propose a hybrid scheme which provides high lookup speed and low worst case update overhead. Our work shows how to exploit the architectural features of TILEPro64 to improve the performance, including many optimization in both single-core and parallelism aspects. Experiment results show by using only 18 cores, we can achieve a lookup throughput of 60Mpps (almost 40Gbps) with low power consumption, which demonstrates great performance potentials in many core processor.
A Triangulated Qualitative Study of Veteran Decision-Making to Seek Care During Heart Failure Exacerbation: Implications of Dual Health System Use

Among Veterans, heart failure (HF) contributes to frequent emergency department visits and hospitalization. Dual health care system use (dual use) occurs when Veterans Health Administration (VA) enrollees also receive care from non-VA sources. Mounting evidence suggests that dual use decreases efficiency and patient safety. This qualitative study used constructivist grounded theory and content analysis to examine decision making among 25 Veterans with HF, for similarities and differences between all-VA users and dual users. In general, all-VA users praised specific VA providers, called services helpful, and expressed positive capacity for managing HF. In addition, several Veterans who described inadvertent one-time non-VA health care utilization in emergent situations more closely mirrored all-VA users. By contrast, committed dual users more often reported unmet needs, nonresponse to VA requests, and faster services in non-VA facilities. However, a primary trigger for dual use was VA telephone referral for escalating symptoms, instead of care coordination or primary/specialty care problem-solving.
Raspberry Supplementation Improves Insulin Signaling and Promotes Brown‐Like Adipocyte Development in White Adipose Tissue of Obese Mice

SCOPE Excessive lipid accumulation in white adipose tissue (WAT) leads to chronic inflammation and metabolic dysfunction. Raspberry (RB) contains high amount of polyphenols and dietary fibers. The objective of the study is to evaluate the effects of RB supplementation on WAT morphology, inflammation, and insulin signaling in high fat diet (HFD)-induced obese mice, and further explore the underlying mechanisms. METHODS AND RESULTS C57BL/6J mice are fed with a control diet or a HFD supplemented with 0 or 5% freeze dried RB for 12 weeks. RB supplementation decreases WAT hypertrophy induced by HFD and suppresses pro-inflammatory cytokines expression and macrophage infiltration in WAT. Meanwhile, RB addition improves insulin sensitivity of HFD-mice. Additionally, RB supplementation drives the browning of WAT (beige adipogenesis), which is associated with elevated PGC-1α and FNDC5/irisin contents. Consistently, the content of beige adipocyte markers including UCP1, PRDM16, Cytochrome C, Cidea, and Elvol3 is enhanced in HFD-mice, which are correlated with increased AMPK phosphorylation and Sirt1 protein contents. CONCLUSION Dietary RB attenuated adipocyte hypertrophy and inflammation of WAT in HFD-mice and improves insulin sensitivity and beige adipogenesis, which is associated with increased FNDC5/irisin content and activation of AMPK/Sirt1 pathway. RB supplementation provides a promising strategy to prevent diet-induced obesity.
Psychological and psychosocial interventions for refugee children resettled in high-income countries

Large numbers of refugee children are arriving in high-income countries. The evidence to date suggests that they have mental health needs that are higher than for the general population and that these are exacerbated by the numbers of traumatic events they have experienced and the post-migration stressors they continue to be exposed to. The importance of a thorough and thoughtful assessment is discussed. Treatments of note are described for post-traumatic stress disorder, family functioning, general mental health problems and school environments. Future opportunities to operationalise outcome measures, develop multimodal interventions and utilise implementation science methodology are considered.
Name Disambiguation Using Atomic Clusters

Name ambiguity is a critical problem in many applications, in particular in the online bibliography systems, such as DBLP and CiteSeer. Previously, several clustering based methods have been proposed although, the problem still presents to be a big challenge for both research and industry communities. In this paper, we present a complementary study to the problem from another point of view. We propose an approach of finding atomic clusters to improve the performance of existing clustering-based methods. We conducted experiments on a dataset from a real-world system: Arnetminer.org. Experiments results show that significant improvements can be obtained by using the proposed atomic clusters finding approach (about +8% and +27% improvements depending on different clustering methods).
Tests on stainless steel continuous beams

An experimental study of stainless steel continuous beams is reported in this paper and the applicability of plastic design methods to such structures is considered. A total of 18 two-span continuous beams were tested. Three crosssection types cold-formed square hollow sections (SHS), cold-formed rectangular hollow sections (RHS) and welded I-sections, and two material grades austenitic EN 1.4301/1.4307 and lean duplex EN 1.4162, were considered. The geometric and material properties of the continuous beam test specimens were carefully recorded and supplemented by tests on simply-supported specimens of the same cross-sections. The test specimens covered a wide range of crosssection slendernesses and two different loading positions were adopted. The experimental results were used to assess the degree of moment redistribution in indeterminate stainless steel structures and the applicability of both conventional and novel plastic design methods, including an extension of the Continuous Strength Method (CSM). Comparisons indicated that conventional plastic design is applicable to stainless steel structures, while greater efficiency can be achieved by considering strain-hardening through the CSM. Further research, considering a wider range of indeterminate structural configurations is ongoing.
Pension Plan Types and Financial Literacy in Later Life

BACKGROUND AND OBJECTIVES The ongoing shift from defined benefit (DB) to defined contribution (DC) pension plans means that middle-aged and older adults are increasingly being called upon to manage their own fiscal security in retirement. Yet, half of older Americans are financially illiterate, lacking the knowledge and skills to manage financial resources. This study investigates whether pension plan types are associated with varying levels of financial literacy among older Americans. RESEARCH DESIGN AND METHODS Cross-sectional analyses of the 2010 Health and Retirement Study (HRS) (n = 1,281) using logistic and linear regression models were employed to investigate the association between different pension plans and multiple indicators of financial literacy. The potential moderating effect of gender was also examined. RESULTS Respondents with DC plans, with or without additional DB plans, were more likely to correctly answer various financial literacy questions, in comparison with respondents with DB plans only. Men with both DC and DB plans scored significantly higher on the financial literacy index than women with both types of plans, relative to respondents with DB plans only. DISCUSSION AND IMPLICATIONS Middle-aged and older adults, who are incentivized by participation in DC plans to manage financial resources and decide where to invest pension funds, tend to self-educate to improve financial knowledge and skills, thereby resulting in greater financial literacy. This finding suggests that traditional financial education programs may not be the only means of achieving financial literacy. Further consideration should be given to providing older adults with continued, long-term exposure to financial decision-making opportunities.
Sampling and Reconstruction of Signals in Function Spaces Associated With the Linear Canonical Transform

The linear canonical transform (LCT) has been shown to be useful and powerful in signal processing, optics, etc. Many results of this transform are already known, including sampling theory. Most existing sampling theories of the LCT consider the class of bandlimited signals. However, in the real world, many analog signals arising in engineering applications are non-bandlimited. In this correspondence, we propose a sampling and reconstruction strategy for a class of function spaces associated with the LCT, which can provide a suitable and realistic model for real applications. First, we introduce definitions of semi- and fully-discrete convolutions for the LCT. Then, we derive necessary and sufficient conditions pertaining to the LCT, under which integer shifts of a chirp-modulated function generate a Riesz basis for the function spaces. By applying the results, we present a more comprehensive sampling theory for the LCT in the function spaces, and further, a sampling theorem which recovers a signal from its own samples in the function spaces is established. Moreover, some sampling theorems for shift-invariant spaces and some existing sampling theories for bandlimited signals associated with the Fourier transform (FT), the fractional FT, or the LCT are noted as special cases of the derived results. Finally, some potential applications of the derived theory are presented.
The application of big data using MongoDB: Case study with SCeLE Fasilkom UI forum data

Big Data is a condition in which data size in a database is very large so it is difficult to be managed. An e-Learning application, like SCeLE Fasilkom UI (scele.cs.ui.ac.id), also has a very large data. SCeLE has hundreds of forum data, and each forum has at least 4000 threads of discussion. In addition, one thread can have at least dozens or hundreds posts. Therefore, it may further experience data growth problem, which will be difficult to be handled by RDBMS, such as MySQL that is currently used. In order to solve this problem, a research been conducted to apply Big Data in SCeLE Fasilkom UI, which implementation is aimed to increase SCeLE's data management performance. The implementation of Big Data in the research used MongoDB as the system's DBMS. The research result showed that MongoDB obtain better results than MySQL in SCeLE Fasilkom UI forum data case in terms of speed.
