Checklist of the marine macroalgae of Vietnam
Authors: Van Nguyen Tu , Le Nhu Hau , Lin Showe-Mei , Steen Frederique , De Clerck Olivier 
Published: June 2013

Abstract
Despite a rich seaweed flora, information about Vietnamese seaweeds is scattered throughout a large number of often regional publications and, hence, difficult to access. This paper presents an up-to-date checklist of the marine macroalgae of Vietnam, compiled by means of an exhaustive bibliographical search and revision of taxon names. A total of 827 species are reported, of which the Rhodophyta show the highest species number (412 species), followed by the Chlorophyta (180 species), Phaeophyceae (147 species) and Cyanobacteria (88 species). This species richness is comparable to that of the Philippines and considerably higher than Taiwan, Thailand or Malaysia, which indicates that Vietnam possibly represents a diversity hotspot for macroalgae. A comparison of the species composition with neighbouring countries yielded surprisingly low similarities. Rather than an indication of a biogeographical pattern, we are of the opinion that the low similarity with neighbouring countries is primarily an artifact resulting from taxonomic inconsistencies. The checklist presented here could serve as a valuable tool to reveal the seaweed diversity in Vietnam and to stimulate intraregional comparative research.

Authors: Vodnik Tatjana , Kaljevic Goran , Tadic Tanja , Majkic-Singh Nada 
Published: June 2013

AbstractBackground:The aim of the study was to identify the diagnostic significance of presepsin in acute abdominal conditions and also to examine the correlation between presepsin, procalcitonin (PCT) and other parameters.Methods:To detect presepsin we used a new rapid method based on a chemiluminescent enzyme immunoassay. The clinical usefulness of presepsin to differentiate bacterial and non-bacterial infection [including systemic inflammation response syndrome (SIRS)] was studied and compared with PCT, C-reactive protein (CRP) and white blood cells (WBC).Results:The presepsin values in different conditions were (mean±standard deviation): healthy group (n=70) 258.7±92.53 pg/mL; SIRS (n=30) 430.0±141.33 pg/mL; sepsis (n=30) 1508.3±866.6 pg/mL. The presepsin values were significantly higher in patients with sepsis than the SIRS group (p<0.0001, Mann-Whitney U-test). The area under the receiver operating characteristics (ROC) curve (AUC) for discriminating of the SIRS from the sepsis patients was 0.996 for presepsin and it was greater than the AUC of PCT (0.912), CRP (0.857) or WBC (0.777).Conclusions:The ROC curve of the SIRS patient without infection and the sepsis patient showed that the presepsin concentration was a significantly sensitive indicator of sepsis and useful marker for the rapid diagnosis of sepsis.
Ionic Liquids as Green Solvents for the Extraction of Endosulfan from Aqueous Solution: A Quantum Chemical Approach
Authors: Pilli Santhi Raju , Banerjee Tamal , Mohanty Kaustubha 
Published: June 2013

Abstract
This work presents a judicious screening of 986 possible ionic liquid (IL) combinations for the removal of Endosulfan using COSMO-RS (Conductor-like Screening Model for Real Solvents) model. Initially, benchmarking studies have been carried out for α-Endosulfan, β-Endosulfan, Endosulfan sulfate, Endosulfan-alcohol, Endosulfan lactone, and Endosulfan ether by comparing COSMO-RS experimental and predicted octanol–water partition coefficients. Thereafter, COSMO-RS selectivity predictions were done on 986 ionic liquid combinations at infinite dilution. The order of selectivity for the five cation groups were found to be as follows: [TBP] > [TIBMP] > [TBMP] > [C2DMIM] > [BEPYR] > [DPPYR] > [C4DMIM] > [C8MPY] > [BTNH] > [BETNH]. Highest selectivity was obtained for phosphonium based IL namely: [TBP][TOS] (212.5). Anions such as [C8H17SO4], [Br], [Sal], [TOS], [MDEGSO4], and [DEC] contributed high selectivities because of the absence of sterical shielding effect around their charge centers. Further capacity and the performance index (PI) values were calculated and predicted along with selectivity. The increasing order of performance index values were found to follow: [TBP][Sal] (1.71+E5) > [DPPYR][Br] (1.07+E6) > [C2DMIM] (1.01+E6) > [C8MPY][Cl] (1.6+E5) > [BETNH][DEC] (1.2+E5).

Hemicelluloses extraction from giant bamboo (Bambusa balcooa Roxburgh) prior to kraft or soda-AQ pulping and its effect on pulp physical properties
Authors: Vena Phumla Faith , Brienzo Michel , del Prado García-Aparicio María , Görgens Johann F. , Rypstra Tim 
Published: June 2013

Abstract
The alkaline and acid preextraction of giant bamboo (Bambusa balcooa Roxburgh), grown in South Africa, before kraft and soda-anthraquinone (AQ) pulping was in focus and the effects of NaOH concentration, temperature, and time on hemicelluloses extraction were studied by means of a statistical experimental design. The NaOH concentration exerted the strongest influence, solubilizing up to 20.4% of the available xylan with 2.0 M NaOH at 90°C for 240 min. The optimal extraction condition was achieved with 1 M NaOH at 90°C for 240 min, in the course of which 13.6% of the xylan was removed; the screened pulp yield was 50.4% without viscosity reduction, whereas the burst index of the handsheets was even improved. In the case of dilute acid preextraction before soda-AQ pulping, 11.3% xylan could be removed without affecting the pulp quality. The viscosity of the pulp was even better than that of pulps from nonextracted bamboo. The biorefinery approach, alkaline preextraction in combination with kraft pulping, is superior to the approach, acid prehydrolysis/soda-AQ pulping.
Pull-out method for direct measuring the interfacial shear strength between short plant fibers and thermoplastic polymer composites (TPC)
Authors: Wang Hao , Tian Genlin , Wang Hankun , Li Wanju , Yu Yan 
Published: June 2013

Abstract
Thermoplastic polymer composites reinforced with short plant fiber are worldwide in focus of research activities. Interfacial shear strength (IFSS) is an important indicator for evaluating the bonding quality between the fiber and the matrix polymer. However, the direct measurement of IFSS is especially difficult in the case of short fibers. In the present article, a method is proposed to this purpose, which is related to the known “fiber pulling out” methodology. In the case of single bamboo fibers, the IFSS in a polypropylene (PP) matrix was on, an average, of 5 MPa, which can be considered as weak. Scanning electron microscopy images revealed a rough inner surface in PP cavities left after fiber pulling out. This is direct evidence that a mechanical interlocking mechanism is active in the interphase between the hydrophilic fibers and the hydrophobic matrix.

Published: June 2013

Abstract
A quasi-experimental study with an experimental group (n=195) and a control group (n=71) was conducted to examine the effectiveness of a leadership and intrapersonal development subject at The Hong Kong Polytechnic University. Results showed that there were no significant differences between the two groups in terms of gender ratio, age, and background family characteristics. Analyses of covariance controlling for pretest differences between the two groups revealed that students in the experimental group generally showed higher levels of psychosocial competence in terms of composite variables that include resilience, social competence, emotional competence, cognitive competence, behavioral competence, self-determination, self-efficacy, and beliefs in the future. In conjunction with other sources of evaluation findings, the present study suggests that this subject is able to promote the holistic development of Chinese university students in Hong Kong.

Authors: Labropoulos Athanasios E. , Varzakas Theo , Anestis Stelios , Kostas Tsoukos , Panagiotou Panagiotis 
Published: June 2013

Abstract
The production of coated foods using batters and breading is widespread in various meat, fish and vegetable products including poultry, i.e. chicken meat cuts. Thus, samples of coated and uncoated chicken meat cuts, i.e. leg and breast, fried or baked were applied in this study. Five batter samples as well as a breading coating sample were evaluated against non coated samples for physicochemical and sensory characteristics. The results indicated that batters enriched with protein produced coating systems with increased crispiness and adhesion while batters enriched with modified corn starches resulted in improved product yields. A combination of wheat flours with modified waxy corn starches resulted in products with excellent adhesive properties, desirable thickness, good crispness and appearance. The cooked meat pieces (coated and uncoated) were packaged after cooling in plastic bags and stored at ‒18C for further analysis, i.e. moisture, water activity, thiobarbituric acid (TBA) and pH values. The results showed reduction in moisture and water activity values and increase in pH and TBA values for the tested (coated and uncoated) products at 0, 1, 4, 8, 12, 16 and 24 weeks of testing periods. Sensory evaluation analysis showed a significant preference for the coated samples compared to the uncoated products.
Influence of Osmotic Pre-treatment on Convective Drying Kinetics of Figs
Authors: Silva Juliana M. , Cantu Muriel G. , Rodrigues Vera , Mazutti Marcio A. 
Published: June 2013

Abstract
This work evaluated the effects of osmotic dehydration on convective drying kinetics of figs. It used the experimental design methodology to evaluate the influence of sucrose concentration, temperature and time on the amount of total soluble solids (TSS) and moisture content of the figs. After the osmotic dehydration, it evaluated the convective drying kinetics at temperatures from 55 to 75°C. A mathematical model was employed to fit the experimental data. From the experimental data of the osmotic dehydration, it was seen that the moisture content of the figs after the treatment was closely related to the amount of TSS of the figs. Low moisture content and high TSS content were obtained for a narrow range of independent variables comprised between 55–60°C, 55–63 wt% and 260–280 min for temperature, sucrose concentration and exposure time, respectively. In the convective drying kinetics of the figs, there were no verified significant differences in the final time of drying of non-treated and osmotically dehydrated figs. However, the shrinkage was considerably reduced in the osmotically treated figs. The use of osmotic treatment enables the obtainment of figs softer than the simple use of convective drying without changing the final time of drying.
Cartels and Rent Sharing at the Farmer–Trader Interface: Evidence from Ghana’s Tomato Sector
Authors: Ngeleza Guyslain K. , Robinson Elizabeth J.Z. 
Published: June 2013

Abstract
Itinerant traders provide an important route for West Africa’s farmers’ to get their perishable produce rapidly to the distant urban markets. But these farmers often accuse the traders of offering “unfairly” low prices while preventing direct access to these markets. Using Ghana’s tomato sector as a case study, we provide the first detailed exploration of the interface between Ghana’s farmers and traders, combining a theoretical model with novel empirical data on daily sales prices and tomato quality. We find that although the prices traders pay farmers are lower than prices in the urban markets, taking into account transport costs, these prices are higher than farmers receive from the local rural market. Our article suggests that policymakers would do better to focus on opening up access to the urban markets rather than on strengthening farmers’ bargaining power with the traders, which restricts market volumes further and harms farmers unable to sell to traders.
Linear Models: A Useful “Microscope” for Causal Analysis
Authors: Pearl Judea 
Published: June 2013

AbstractThis note reviews basic techniques of linear path analysis and demonstrates, using simple examples, how causal phenomena of non-trivial character can be understood, exemplified and analyzed using diagrams and a few algebraic steps. The techniques allow for swift assessment of how various features of the model impact the phenomenon under investigation. This includes: Simpson’s paradox, case–control bias, selection bias, missing data, collider bias, reverse regression, bias amplification, near instruments, and measurement errors.
Revisiting a Discrepant Result: A Propensity Score Analysis, the Paired Availability Design for Historical Controls, and a Meta-Analysis of Randomized Trials
Authors: G. Baker Stuart , S. Lindeman Karen 
Published: June 2013

AbstractThere is an ongoing controversy over whether epidural analgesia for women in labor increases the probability of Caesarean section. Previous research compared results from three methods for estimating the effect of epidural analgesia on the probability of Caesarean section: a propensity score analysis, the paired availability design for historical controls, and meta-analysis of randomized trials. The propensity score analysis and a paired availability design gave substantially different results with the latter in closer agreement with results of a meta-analysis of randomized trials. We updated this investigation in three ways. First, we discussed the use of causal graphs for variable selection in the propensity score analysis. Second, we introduced new extrapolation estimates to improve generalizability for the paired availability design and the meta-analysis of randomized trials with crossovers. Third, we included the results from more recent studies. This analysis provides a window into various topics in causal inference and comparative effectiveness research.

Abstract.
We prove approximate Lipschitz stability for non-overdetermined inverse
scattering at fixed energy with incomplete data in dimension . Our
estimates are given in uniform norm for coefficient difference and
related stability precision efficiently increases with increasing energy
and coefficient difference regularity.
In addition, our estimates are rather optimal even in the Born approximation.
Single-Channel Speech Enhancement Techniques for Distant Speech Recognition
Authors: Ashwini Jaya Kumar , Kumaraswamy Ramaswamy 
Published: June 2013

AbstractThis article presents an overview of the single-channel dereverberation methods suitable for distant speech recognition (DSR) application. The dereverberation methods are mainly classified based on the domain of enhancement of speech signal captured by a distant microphone. Many single-channel speech enhancement methods focus on either denoising or dereverberating the distorted speech signal. There are very few methods that consider both noise and reverberation effects. Such methods are discussed under a multistage approach in this article. The article concludes with a hypothesis that the methods that do not require an a priori reverberation impulse response is desirable in varying the environmental conditions for DSR applications such as intelligent home and office environments, humanoid robots, and automobiles rather than the methods that require an a priori reverberation impulse response.

Abstract
Autophagy is an intracellular process that maintains homeostasis by the removal of damaged organelles and proteins. A single nucleotide polymorphism (SNP) in the autophagy-related 16-like 1 (ATG16L1) gene results in decreased autophagy. We evaluated whether the ATG16L1 polymorphism influenced the time to delivery during labor induction in pregnant women with an unfavorable cervix. DNA from 69 women with an unfavorable cervix who required labor induction due to post-term (>294 days) (n=26), oligohydramnios (n=17), hypertension or pre-eclampsia (n=10), abnormal fetal heart rate (n=8), diabetes (n=3) or other reasons (n=5) was tested by gene amplification and endonuclease digestion for a SNP in ATG16L1 (rs2241880). The mean hours (SD) from induction to delivery was 20.8 (9.7) for women who were A,A homozygotes, 19.2 (8.8) for A,G heterozygotes and 14.3 (6.6) for homozygote carriers of the G,G variant (P=0.03 A,A vs. G,G, P=0.04 A,A/A,G vs. G,G). The G,G prevalence was 24.4% and 4.2% for those who delivered in ≤24 and >24 h, respectively (P=0.04). There was no difference in genotype distribution by indication for induction. A decreased genetic capacity for autophagy may be beneficial in women with an unfavorable cervix whose labor has to be induced.
Willensgebundenheit und notwendige Kontingenz als Bedingungen von Willensfreiheitserfahrungen
Authors: Mühling Markus 
Published: June 2013

Zusammenfassung
Nach einer Besprechung der empirischen Ergebnisse und der unterschiedlichen ontologischen Voraussetzungen neurowissenschaftlicher Forschung hinsichtlich der Willensfrage fragt diese Untersuchung, ob der menschliche Wille als frei oder als gebunden zu charakterisieren ist und ob ein angemessenes Verständnis des menschlichen Willens in ein deterministisches oder indeterministisches Weltverständnis einzubetten ist. Nachdem eine Behandlung von Luthers Position zur Fragestellung und eine Untersuchung der gegenwärtigen Debatte vorgenommen wurde, werden die Hauptthesen formuliert: Unter der Voraussetzung eines Begriffs der menschlichen Person als eines partikularen, eschatisch konstituierten, gegenwärtig prozedierenden Voneinander-und-Füreinanderseienden, das unter der Alternative steht, eine ver-rückte oder zurechtgerückte Selbsterschlossenheitslage zu besitzen, ist der menschliche Wille als solcher als gebunden an verschiedene Relate zu verstehen: zu extern und intern bestimmbar Bestimmendem sowie zu extern und intern kontingent-unbestimmbar Bestimmendem. Der menschliche Wille ist daher immer gebunden. Damit einher geht eine spezifische Form des Kompatibilismus, der eine Kompatibilität sowohl zu deterministischen als auch zu indeterministischen Weltverständnissen auszudrücken hat. Am Ende werden Vorschläge zur Willensfreiheitserfahrung unter der Bedingung eines ontisch gebundenen Willens unterbreitet und Konsequenzen für den Verantwortungsbegriff gezogen.
Preparation of starch-based styrene acrylate emulsion used as surface-treatment agent for decorative base paper
Authors: Xu Jianfeng , Long Ling , Hu Huiren 
Published: June 2013

Abstract
A series of cationic starch (CS-8)-based styrene (St) acrylate latex preparations was prepared by the core-shell emulsion polymerization method. The latex was used in the surface-treatment of decorative base papers, for good printability and absorbability. CS-8, which has a low relative viscosity, was used as the emulsifier and dispersant. The influencing factors (dosage of CS-8 as well as the kinds and dosages of functional monomers) were studied and the optimal conditions were achieved. Then, the products were characterized by scanning electron microscopy (SEM), Fourier-transform infrared (FT-IR), laser particle size analysis and particle charge detection. The results showed that the excellent performance and good surface-treatment effects of the St acrylate emulsion (SAE) were achieved when the reaction conditions were as follows: 10 wt% starch, 2 wt% methacryloyloxyethyltrimethyl ammonium chloride (DMC) as the cationic monomer and 20 wt% ethyl acrylate (EA) as the acrylate monomer. Under the optimal conditions, the latex particle size was around 160 nm, the latex viscosity was 10 mPa·s and the latex charge density was 0.60 mmol·l-1. The printability of the decorative base paper was significantly improved and the absorbability of the paper sheet was maintained. The surface-treatment effect of the cationic starch-based SAE was superior to that of commercial polyurethane (PU).
