Authors: Kadić Ana , Denić-Jukić Vesna , Jukić Damir 
Published: November 2017

Abstract
The objective of this work is the study of two adjacent karst springs, Jadro and Žrnovnica, in Croatia. This work focuses on the effects of temperature, relative humidity, rainfall and discharges on the hydrological behavior and relations of two adjacent karst springs. Partial correlation analysis reveals the type of the control signal that affects the cross-correlation function between an input and output signal. It has been confirmed that in the case of the adjacent karst springs Jadro and Žrnovnica, the discharge of the Žrnovnica Spring has an impact on the rainfall-discharge relation of the Jadro Spring. The demonstrated approach represents an improvement in investigating the relations of adjacent karst springs and could be used as an integral part of their hydrological and hydrogeological investigations, considering that the necessary data can occur in a relatively simple and inexpensive manner.
Hydraulic characteristics of varying slope gradients, rainfall intensities and litter cover on vegetated slopes
Authors: Sun Jiamei , Fan Dengxing , Yu Xinxiao , Li Hanzhi 
Published: November 2017

Abstract
Litter produced by forests performs crucial functions in rainfall interception and soil conservation, particularly in the condition that larger raindrops formed by canopy accelerate soil erosion. To explore how forest litter exerts runoff hydrological characteristics and sediment yield processes, experiments on forest covered (Vitexnegundo var. heterophylla) slopes were conducted under various combinations of rainfall intensities and slope gradients. The results showed that litter reduced runoff yield rate by 9–31% and reduced sediment yield rate by 65–90%, with mean runoff and sediment reductions of 18% and 76% for all treatments. On forest covered slopes, Reynolds number and runoff power generally increased with the increase in both rainfall intensity and slope gradient. Litter layer reduced Reynolds number and runoff power with 8–29% and 56–80%, respectively. Darcy–Weisbach resistance coefficient decreased by increasing rainfall intensity and slope gradient. Litter layer increased Darcy–Weisbach resistance coefficient by three to nine times. Relationships between sediment yield rate and Reynolds number, runoff power, Darcy–Weisbach resistance coefficient were described by exponential, linear, power functions, respectively. The critical runoff power values for slopes with and without litter were 0.0027 and 0.0010 m/s, respectively. Reynolds number was the best hydrodynamic parameter for dynamic erosion characterizing.
Immobilization of halophilic yeast for effective removal of phenol in hypersaline conditions

Published: November 2017

Abstract
A halotolerant yeast strain of Candida sp. was purified for phenol biodegradation and was immobilized in alginate and nano-SiO2. The concentration of nanoscale SiO2 was optimized and phenol degradation performance with different initial phenol concentrations was evaluated. Three common kinetic models were used to correlate the experimental data. The effects of pH and salinity on phenol biodegradation were also investigated. It was found that 1.0% (w/v) was the optimal nano-SiO2 concentration and the immobilized cells had a better phenol removal performance compared to free cells. More than 99% of 600 mg l−1 phenol was removed by the immobilized strains within 48 h. The immobilized cells also showed highest phenol degradation rates when pH and salinity were 6.5 and 0%, respectively. The high removal efficiency of phenol in reusability tests indicated the promising application of the immobilized Candida strain in phenol degradation under hypersaline conditions over a long period.
Test of precoat filtration technology for treatment of swimming pool water
Authors: Christensen Morten Lykkegaard , Klausen Morten Møller , Christensen Peter Vittrup 
Published: November 2017

Abstract
The technical performance of a precoat filter was compared with that of a traditional sand filter. Particle concentration and size distribution were measured before and after the filtration of swimming pool water. Both the sand and precoat filters could reduce the particle concentration in the effluent. However, higher particle removal efficiency was generally observed for the precoat filter, especially for particles smaller than 10 μm in diameter. Adding flocculant improved the removal efficiency of the sand filter, resulting in removal efficiencies comparable to those of the precoat filter. Three powders, i.e., two types of perlite (Harbolite® and Aquatec perlite) and cellulose fibers (Arbocel®), were tested for the precoat filter, but no significant difference in particle removal efficiency was observed among them. The maximum efficiency was reached within 30–40 min of filtration. The energy required for the pumps increased by approximately 35% over a period of 14 days. The energy consumption could be reduced by replacing the powder on the filter cloth. The sand filter was backwashed once a week, while the powder on the precoat filter was replaced every two weeks. Under these conditions, it was possible to reduce the water used for cleaning by 88% if the precoat filter was used instead of the sand filter.

Aim. This trial was aimed at comparing the efficacy and safety of sirolimus-eluting coronary stent “Calypso” (Angioline) and everolimus-eluting coronary stent “XiencePrime” (Abbott Vascular) when used for treatment of ischemic heart disease patients.Methods. The trial included patients suitable for coronary revascularization with coronary stenting. They underwent a standard revascularization procedure and were randomized in 2:1 ratio to receive “Calypso” coronary stent (Angioline) (n = 407) or “XiencePrime” coronary stent (AbbottVascular) (n = 203). The follow-up period was 12 months. In order to detect restenosis (secondary endpoint), angiographic follow-up was performed in 20% of cases at 12 months. The trial protocol had no limitations regarding the length of lesions, number of target lesions and number of implanted stents. The main exclusion criterion was STEMI. The composite primary endpoint included one-year target lesion-related complications determined as cardiogenic death, target vessel myocardial infarction, clinically indicated target lesion revascularization. The primary endpoint data were evaluated by an independent committee.Results. In the trial, 55% of patients had acute coronary syndrome with ST elevation and type C lesions were detected in 46% of cases. In “Calypso” and “XiencePrime” groups, TLF occurred in 5.4% and 6.4% respectively (absolute risk difference in TLF accounted for 1%, 95% CI [---;2.1%]; p non-inferiority = 0.017). Thus, the hypothesis of non-inferiority of “Calypso” as compared to “XiencePrime” was confirmed. The incidence of stent thrombosis (definite and probable) was relatively low and had no significant differences between “Calypso” and “XiencePrime” groups (0.73% and 0%; p>0.05). Definite stent thrombosis was noted in two cases in the “Calypso” group (0.49%), in one case the cause of thrombosis turned out to be incomplete stent expansion after implantation.Conclusion. “Calypso” sirolimus eluting stent was not inferior to “XiencePrime” everolimus-eluting stent in treating patients with coronary heart disease.Received 7 November 2017.

High-Throughput Screening Strategies for the Development of Anti-Virulence Inhibitors Against Staphylococcus aureus
Authors: Cai Xiaodan , Zheng Weihao , Li Zigang 
Published: November 2017

Background:The increasing threats of antibiotic resistance urge the need for developing new approaches to combat bacterial infections including those caused by Staphylococcus aureus (S. aureus). Unlike conventional antibiotics that aim to kill bacteria or inhibit their growth, targeting bacterial virulence may be a promising alternative approach, which imposes less selective pressure for antibiotic resistance in future generations.Objective:Our goal is to provide a systematic review about developing high-throughput screening (HTS) strategies for the identification of inhibitors targeting virulence of S. aureus. We also describe an overview of virulence regulatory pathways for potential antivirulence targets.Methods:We focus on five potential targets or target families, including agr quorum sensing system, SarA/MgrA protein family, sortase A, Clp protease and eukaryotic-like Ser/Thr phosphatase (Stp1). For each target, we introduce its role in virulence regulation, summarize the HTS approaches that are used to identify novel anti-virulence inhibitors, and discuss the advantages and disadvantages of these strategies.Conclusion:The discovery of anti-virulence inhibitors via HTS underlines the promising potential of anti-virulence therapy for S. aureus. The development of HTS strategies can facilitate the identification of novel anti-virulence inhibitors for combating S. aureus infection, and may also advance our understanding on virulence regulation in S. aureus.

Objective: Nowadays proper detection of cognitive impairment has become a challenge for
the scientific community. Alzheimer's Disease (AD), the most common cause of dementia, has a high
prevalence that is increasing at a fast pace towards epidemic level. In the not-so-distant future this fact
could have a dramatic social and economic impact. In this scenario, an early and accurate diagnosis of
AD could help to decrease its effects on patients, relatives and society. Over the last decades there have
been useful advances not only in classic assessment techniques, but also in novel non-invasive screening
methodologies.

Methods:
Among these methods, automatic analysis of speech -one of the first damaged skills in AD
patients- is a natural and useful low cost tool for diagnosis.

Results:
In this paper a non-linear multi-task approach based on automatic speech analysis is presented.
Three tasks with different language complexity levels are analyzed, and promising results that encourage
a deeper assessment are obtained. Automatic classification was carried out by using classic Multilayer
Perceptron (MLP) and Deep Learning by means of Convolutional Neural Networks (CNN) (biologically-
inspired variants of MLPs) over the tasks with classic linear features, perceptual features, Castiglioni
fractal dimension and Multiscale Permutation Entropy.

Conclusion:
Finally, the most relevant features are selected by means of the non-parametric Mann-
Whitney U-test.
Easy Screening for Mild Alzheimer's Disease and Mild Cognitive Impairment from Elderly Speech
Authors: Kato Shohei , Homma Akira , Sakuma Takuto 
Published: November 2017

Objective: This study presents a novel approach for early detection of cognitive impairment
in the elderly. The approach incorporates the use of speech sound analysis, multivariate statistics, and
data-mining techniques. We have developed a speech prosody-based cognitive impairment rating
(SPCIR) that can distinguish between cognitively normal controls and elderly people with mild Alzheimer's
disease (mAD) or mild cognitive impairment (MCI) using prosodic signals extracted from elderly
speech while administering a questionnaire. Two hundred and seventy-three Japanese subjects (73
males and 200 females between the ages of 65 and 96) participated in this study. The authors collected
speech sounds from segments of dialogue during a revised Hasegawa's dementia scale (HDS-R) examination
and talking about topics related to hometown, childhood, and school. The segments correspond to
speech sounds from answers to questions regarding birthdate (T1), the name of the subject's elementary
school (T2), time orientation (Q2), and repetition of three-digit numbers backward (Q6). As many prosodic
features as possible were extracted from each of the speech sounds, including fundamental frequency,
formant, and intensity features and mel-frequency cepstral coefficients. They were refined using
principal component analysis and/or feature selection. The authors calculated an SPCIR using multiple
linear regression analysis.

Conclusion:
In addition, this study proposes a binary discrimination model of SPCIR using multivariate
logistic regression and model selection with receiver operating characteristic curve analysis and reports
on the sensitivity and specificity of SPCIR for diagnosis (control vs. MCI/mAD). The study also reports
discriminative performances well, thereby suggesting that the proposed approach might be an effective
tool for screening the elderly for mAD and MCI.
