High efficient degradation of Cefixime using UV/TiO2 photocatalytic process: A comparison between photocatalytic and photolytic

Introduction: The existence of pharmaceuticals in aquatic ecosystem, their persistence and possible effects on living organisms and inefficient systems in removal of these compounds from water and wastewater are a growing concern. In this research, the UV/TiO2 photocatalytic degradation of Cefixime was investigated so as to identify if this method was efficient for removal of Cefixime or not. Methods: The experimental parameters like as primary concentration of Cefixime, catalyst dosage, solution pH and time were assessed and optimized. The photocatalytic analysis was based on residual Cefixime identification by HPLC. The chromatographic conditions were comprised of a reversed‐phase C18 column with mobile phase consisting of 45:55 v/v mixture of Acetonitrile: water. Results: The optimum removal efficiency for Cefixime was obtained after 60 min (90.98) when 1 mg/L TiO2 was used at pH=3. The increase of catalyst concentration from 1 to 70 mg/L led to a decrease in degradation efficiency. Conclusion: According to results, UV/TiO2 process could be a promising technique for the removal of Cefixime with good efficiency in a relatively short reaction time
Addressing the healthcare needs of an ageingpopulation: the need for an integratedsolution

All stakeholders involved in healthcare are well aware of the ticking time bomb of our ageing world with demand exceeding supply even within the most affluent of countries. The Director- General of the World Health Organisation (WHO) has recently drawn global attention to the fact that even in low income countries people are living longer; however pointedly adds that longevity is not enough. To benefit society as a whole there needs to be a refocus on how later years in life are significant to the older person; with attention to dignity and good health [1].
Trace element concentrations in freshwater mussels and macrophytes as related to those in their environment

This study was primarily designed to contribute to the debate "Do accumulator species reflect the element contamination level of their environment? " This research was carried out: 1) to know the distribution of 15 trace elements and calcium in shell and soft tissues of three species of freshwater mussels and macrophytes; 2) to compare the accumulation capacity of each trace element by mussels and by eight species of macrophytes and 3) to test the relationships between the metal concentrations in the mussels and macrophytes and those in water and sediments. The variability of element residues in the mussels is the major limit to accumulator monitoring. The most important causes are: seasonal cycle, physical environment and biological factors such as the size, age and growth rate. This research was designed to eliminate the consequence of variability deriving from the season and the environment. To this end the mussels and macrophytes were collected at the same time from the same habitat: Ranco Bay, Lago Maggiore, Northern Italy. In addition, the element concentrations in more size-classes of the most abundant mussel species (Unio pictorum and Dreissena polymorpha) were measured. Trace elements were analyzed by Inductive Coupled Plasma-Mass Spectrometry (ICP-MS). By arranging the data in sequences of decreasing element concentrations in the organisms as well as in water and sediments, we were able to compare the accumulating ability of the tested species and evaluate their capacity to reflect environmental availability. Neither the sequences in the shell nor those in the tissues were similar to the sequence in the water. The differences between the sequences of the mussel tissues and those of the sediments were less striking than those between shells and sediments. Similar results were obtained by macrophytes. In conclusion, the results of this study (which mimics the monitoring practice) prove that bioaccumulators cannot be used to evaluate the pollutant levels of the environment at the time of collection, since no relationship between metal concentrations in the species and those in the water was found and the relationship with the sediments was very weak. Bioaccumulators can be regarded as a useful tool in long-term studies to follow pollutant variations in the same environment or when substantial differences in pollutant concentrations in different environments were found. This monitoring method yields reliable results to detect new pollutants contaminating the environment, such as artificial radioisotopes, or to follow year to year variations by analyzing pollutant concentrations in the shell layers.
Serum and Urine Level of IP-10 in Patients with HCV infection Based on Clinical and Virological Markers

Background and Aims: IP-10 molecule is a new biomarker to predict response to treatment in chronic HCV infection. Also urine IP-10 has been suggested as a biomarker in other infections. But already, it has low data in urine as well as serum level of IP-10 for HCV infection. The aim of this study was to assess urine and serum level of IP-10 in patients with type 1 and 3a HCV infection. Materials and Methods: In this case-control study, 105 patients with HCV infection were involved in three 35 people groups. Blood and urine sample of all patients was collected to determine IP-10 level. Finally, data analysis was reported using SPSS, mean statistics analysis and T test. Results: The age mean was 41.611.2 ranging 21-68. Urine and serum level of IP-10 in patient group was significantly higher than control (p=0.001). Serum level of IP-10 based on HCV genotype was higher significantly in genotype 1a than 3a (p=0.001) but there was no significant difference of urine IP-10 level between genotypes 1a and 3a. Conclusions: The results show IP-10 is a proper marker to determine the prognosis of fibrosis and progress liver inflammation and on the other hand, the prediction of response to treatment differs in various genotypes of HCV infection.
Exchange volatility and trade performance in Morocco and Tunisia: what have we learned so far?

This paper attempts to assess two interesting issues for two small open economies (Morocco and Tunisia). First, it analyses the historical behaviour of nominal exchange rate, differential price and real exchange rate uncertainties. Second, it investigates the stability of the interaction between exchange volatility and exports in nominal and real terms. Our main results reveal that the effect of differential price volatility on exports exceeds that of nominal exchange rate by a large margin in terms of duration of persistence, ARCH and GARCH effects and intensity of shock. The relationship appears complex. In Morocco, it is negative and significant in 75.82% (as average) of cases in nominal terms and in 77.22% in real terms. This link is stronger in Tunisia with averages, respectively, equal to 85.88% and 89.99%. We associate the apparently mixed results to the differential price uncertainty itself sensitive to ups and down oil price movements, switching regime and leverage effects.

This paper presents an advance of a novel approach for automated diagnosis, on basis of classification of Magnetic Resonance Imaging (MRI) human brain images. Wavelet Transform is utilized for feature extraction. For feature selection Particle Swarm Optimization (PSO) is applied to decrease features size. To optimize support vector machine (SVM) parameters we utilize Cuckoo Search and Support Vector Machine (CS-SVM) model. SVM is applied to create the classifier.
Leveraging Catalog Knowledge Graphs for ery A ribute Identification in E-Commerce Sites Suhas Ranganath

Millions of people use online e-commerce platforms to search and buy products. Identifying aributes in a query is a critical component in connecting users to relevant items. However, in many cases, the queries have multiple aributes, and some of them will be in conflict with each other. For example, the query “maroon 5 dvds” has two candidate aributes, the color “maroon” or the band “maroon 5”, where only one of the aributes can be present. In this paper, we address the problem of resolving conflicting attributes in e-commerce queries. A challenge in this problem is that knowledge bases like Wikipedia that are used to understand web queries are not focused on the e-commerce domain. E-commerce search engines, however, have access to the catalogwhich contains detailed information about the items and its aributes. We propose a framework that constructs knowledge graphs from catalog to resolve conflicting aributes in e-commerce queries. Our experiments on real-world queries on e-commerce platforms demonstrate that resolving conflicting aributes by leveraging catalog information significantly improves aribute identification, and also gives out more relevant search results.
Higgs triplets at like-sign linear colliders and neutrino mixing

We study the phenomenology of the type-II seesaw model at a linear e{sup -}e{sup -} collider. We show that the process e{sup -}e{sup -}{yields}{alpha}{sup -}{beta}{sup -} ({alpha}, {beta}=e, {mu}, {tau} being charged leptons) mediated by a doubly charged scalar is very sensitive to the neutrino parameters, in particular, the absolute neutrino mass scale and the Majorana CP-violating phases. We identify the regions in parameter space in which appreciable collider signatures in the channel with two like-sign muons in the final state are possible. This includes Higgs triplet masses beyond the reach of the LHC.
Novel Ultrasonic Broadcast Communication System

With the development of Internet of Thing (IoT), everything is ready to connect with each other. Nevertheless the limited electromagnetic wave band resources cannot meet this demand, which inspire us to find another communication method. Ultrasound with good directivity and inaudibility can be a good media for wireless communication. In this paper, we designed a novel ultrasonic broadcast communication system exploiting the non-linearity in microphone hardware. In this system, by utilizing the directivity of ultrasound we achieved space division multiple access(SDMA) scheme. To make an automatically communication we using a machine learning method to recognize the modulation method by support vector machine(SVM). And we have achieved a amplitude modulation for voice transmission which can be easily applied in museum as an inaudible interpreter. We also achieve the frequency modulation for digital data transmission which can be easily applied in supermarket or exhibition to provide detailed information for commodity without network connection. Evaluation result shows: SDMA can be easily applied by ultrasound and the voice transmission can simultaneously exist 3 channels in a same space, which is very easy to setup in many application scenarios. The transmission rate in digital data transmission up to 6 kbps.
OVERCOMING BARRIERS TO ANTI-EPILEPTIC TREATMENT: A LIFE-TIME SENTENCE?

Epilepsy, like many other mental illnesses, is more prevalent than is commonly acknowledged. Moreover, its social and economic burden is excessive for the individual, family, health system and country at large. People with epilepsy have low quality of life and productivity. They and their families are stigmatized and discriminated against. Doctors with Africa - CUAMM, has operated a project for epilepsy treatment together with the local health authorities in Nebbi and Arua districts since 2005, aimed at increasing access to free, effective anti-epileptic medicines. Despite the availability of the medicines, the attendance of many enrolled patients has been erratic. This study was done to document the level of adherence to treatment, the reasons for the observed health-seeking pattern and to assess the feasibility of sustainability of enhanced epilepsy treatment services once the project ended. Retrospective analysis of records of all patients registered in 2004 and 2005 was done in order to determine the level and pattern of adherence. A cross-sectional survey of 93 patients, selected according to the documented patterns of clinic attendance, was done to investigate the reasons for the observed pattern of healthcare use. Assessment of feasibility of sustainability was done by interviewing key informants and reviewing records of expenditures on anti-epileptic medicines for 2005. Conducted in 2006, the study shows that about 84.5% of the enrolled patients missed at least one appointment over the two-year period of follow-up, with about one third missing all the clinics since enrolment. A typical patient missed about 60% of all the appointments. The overall attendance level at any given time was at a low 40% (30% for those registered in 2005 and 50% for those registered in 2004). There was wide variation in the magnitude and frequency of defaulting at the different sites. Younger and older patients defaulted more often than the middle-aged groups, just as female patients defaulted more frequently than the male counterparts. The reasons for the poor compliance were multiple, patient-specific and often acting simultaneously. The most critical and cross-cutting included distance from the health facility, family support, persistent health education and individual patient/family counseling. The mobilisers (often epilepsy patients themselves) were pivotal in patient/family education and counseling as well as reminding patients about clinic days. The most important adherence-promoting health systems factors were the regular availability of effective medicines and the vertical nature of the delivery system. There were several constraints working against sustainability of enhanced epilepsy care, including technical competence of the health workers, regulatory limitations that forbid the use of some anti-epileptic medicines at some levels of health care, negative staff attitude and high investment levels in ensuring constant availability of anti-epileptic medicines.
Sequestration of carbon in harvested wood products for the United States

The Intergovernmental Panel on Climate Change (IPCC) provides guidelines for countries to report greenhouse gas removals by sinks and emissions from sources. These guidelines allow use of several accounting approaches when reporting the contribution of harvested wood products (HWP) under the United Nations Framework Convention on Climate Change. Using extensions of methods suggested by the IPCC and a software model called WOODCARB II in Microsoft Excel®, this paper presents estimates of the U.S. HWP contribution to annual greenhouse gas removals in the agriculture, forestry, land use, and land use change sector. In 2005, the contribution to removals was 30 Tg (million metric tons) C (carbon) and 31 Tg C for the Production and Atmospheric Flow Approaches, respectively, and 44 Tg C for the Stock Change Approach. This range is 17 to 25 percent of C removals by forests, or would offset 42 percent to 61 percent of residential natural gas C emissions in 2005. The contribution has declined under the Production and Atmospheric Flow Approaches since 1990 and has increased under the Stock Change Approach. The Stock Change estimate has increased because it explicitly includes C in increasing net imports of wood and paper products. The contribution estimates were validated by adjusting the half-life of products in use in order to match independent estimates of carbon in housing in 2001 and annual wood and paper discards to solid-waste disposal sites (SWDS) during 1990 to 2001. Estimates of methane emissions from wood and paper in landfills were also checked against independent estimates of total landfill methane emissions. A Monte-Carlo simulation used to assess the effect of uncertainty in inputs suggests the 90 percent confidence interval for removal contribution estimates under the three approaches is within -23% to +19%.
Can a Stock Index Be Less Efficient than Underlying Shares? An Analysis Using Malta Stock Exchange Data

Researchers often assume that stock market indices are the best possible yardstick in terms of market efficiency. The paper investigates this concept using data from the Malta Stock Exchange (MSE). The fact that a significant number of MSE shares do not trade everyday, may imply that the most liquid shares on this exchange are more efficient than the market index, whose value is dependent on shares of varying liquidity levels - including the less liquid ones. The paper applies various tests to compare the pricing efficiency of the MSE Index to that of the most liquid share quoted on the exchange. It is found that the MSE Index is still more efficient than the latter share.
Prefix Caching for Video Streaming in Wireless D2D Networks

This paper introduces a new prefix caching strategy for video streaming in wireless device-to-device (D2D) networks. Each user caches several initial sequential segments of video files and can share their cached parts via D2D communications. Moreover, video playing and downloading happen simultaneously. We evaluate the system performance by playback delay rather than traditional download delay. Specifically, we formulate the average playback delay minimization problem in terms of cache placement. By relaxing the integer constraints of the decision variables, the original problem becomes convex and then we can find a lower bound of the optimal solution. Next we propose a greedy algorithm to solve the original minimization problem. And extensive simulation results reveal that our proposed video caching strategy has great performance in comparison with heuristic benchmark schemes.
Source-position transformation: an approximate invariance in strong gravitational lensing

The main obstacle for gravitational lensing to determine accurate masses of deflectors, or to determine precise estimates for the Hubble constant, is the degeneracy of lensing observables with respect to the mass-sheet transformation (MST). The MST is a global modification of the mass distribution which leaves all image positions, shapes and flux ratios invariant, but which changes the time delay. Here we show that another global transformation of lensing mass distributions exists which almost leaves image positions and flux ratios invariant, and of which the MST is a special case. Whereas for axi-symmetric lenses this source position transformation exactly reproduces all strong lensing observables, it does so only approximately for more general lens situations. We provide crude estimates for the accuracy with which the transformed mass distribution can reproduce the same image positions as the original lens model, and present an illustrative example of its performance. This new invariance transformation most likely is the reason why the same strong lensing information can be accounted for with rather different mass models.
Equilibrium bed-concentration of nonuniform sediment

Knowledge of the equilibrium bed-concentration is vital to mathematical modeling of the river-bed deformation associated with suspended load but previous investigations only dealt with the reference concentration of uniform sediment because of difficulties in observation of the bed-concentration. This work is a first attempt to develop a theoretical formula for the equilibrium bed-concentration of any fraction of nonuniform sediment defined at the bed-surface. The formula is based on a stochastic-mechanistic model for the exchange of nonuniform sediment near the bed, and described as a function of incipient motion probability, non-ceasing probability, pickup probability, and the ratio of the average single-step continuous motion time to static time. Comparison of bed-concentration calculated from the proposed formula with the measured data showed satisfactory agreement, indicating the present formula can be used for solving the differential equation goverming the motion of suspended load.
The stratigraphic distribution and occurrence of South African fossil Amphibia in the Beaufort beds

A short account is given of the distribution and occurrence of fossil amphibians from the Beaufort succession, based on analyses of specimens in various South African and overseas insti­ tutions. Their occurrence is based on the re-examination of all the localities which have yielded amphibian remains to date and on field observations during the course of collecting. Attention is drawn to the paucity of fossil amphibians throughout the Beaufort palaeontologi­ cal record. Possible causes of this paucity are discussed .
Relativity of quantum superpositions

In modern physics only relative quantities are considered to have physical significance. For example, position assigned to a system depends on the choice of coordinates, and only relative distances between different systems have physical relevance. On the other hand, in quantum theory the scenario where one system, A, is localised around certain position while another system B is in a spatial superposition is considered to be physically different from the scenario where A is in a superposition, while B is localised. Different physical effects are anticipated in the two scenarios especially when the two systems have widely different masses. Here we show that for any superposed amplitudes that are related by a symmetry transformation, the above scenarios are physically equivalent: probabilities for any measurement are the same whether we assign the superposition state to system A or to system B. More generally, linearity of quantum theory guarantees that if a theory is invariant under some symmetry transformations it is necessarily also invariant under their arbitrary `superpositions'. Thus the notion of a superposition turns out to be relative to the choice of coordinates, once it is realised that relations between coordinates do not need to be classical.
Hall Thruster Erosion Prediction Using A Hydrodynamic Plasma Model And Sputtering Simulation

One of the challenges facing further utilization of Hall thrusters for space missions is establishing valid lifetime predictions. A combination of the use of a hydrodynamic code and a molecular dynamics code is presented for Hall thruster erosion modeling. The hydrodynamic model simulates the plasma flow within the acceleration channel of an SPT-100 thruster to calculate the ion flux to the walls. The molecular dynamics model simulates the sputtering of boron nitride, a common Hall thruster wall material, to calculate sputter yields at low ion impact energies. Results from both models are shown as well as a qualitative comparison of sample erosion profiles with experimental data.
Does Financial Development Influence Economic Growth in India

In earlier times economic growth is commonly discussed in terms of real GDP per capita, industrial output, capital, labor force, educational growth, savings, investments, inflation and trade openness of the country. Including all the factors, financial development plays a crucial role for country’s economic growth. It is a multidimensional concept and constitutes a potentially important mechanism for long run economic growth. The study makes use of the Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) methods for unit root test and the variables were found to be stationary, though not in their level form but in their first difference. Autoregressive Distributed Lag (ARDL) bound testing approach to co-integration techniques and Error Correction Model (ECM) is used for long run and short run causality in Indian time series data covering the period from 1980 to 2011. The paper finds a co-integration relationship between financial sector development and economic growth. It concludes that financial development can be interpreted as one of the long run determinants of economic growth, not vice-versa.
