Chemical and ultrastructural changes of ash wood thermally modified using the thermo-vacuum process: I. Histo/cytochemical studies on changes in the structure and lignin chemistry
Authors: Kim Jong Sik , Gao Jie , Terziev Nasko , Cuccui Ignazia , Daniel Geoffrey 
Published: November 2014

AbstractChanges in structure and lignin chemistry were investigated in ash wood thermally modified (TMW) by the thermo-vacuum (Termovuoto) process for 3 h at 190–220°C by means of light, fluorescence, and transmission electron (TEM) microscopy combined with histo/cytochemistry. Variation in changes in native cell color in TMWs was positively correlated with differences in lignin content between cell types and cell wall regions in the reference wood. Histochemical staining showed increasing amounts of acidic groups in TMWs with different response to ethanol extraction between secondary cell walls and CMLcc(compound middle lamella/middle lamella cell corner) regions. Fluorescence microscopy of TMWs and references showed a difference in intensity and color emission of lignin autofluorescence, reflecting modification of lignin in TMWs. Changes in histochemistry and fluorescence were prominent at and above 200°C. With TEM, increased intensity of lignin staining and distortion of fiber S1layers were detected in TMW treated for 3 h at 220°C (TMW3 h, 220°C). TMW3 h, 220°Cdiffered significantly in molecular ultrastructure of fiber cell walls compared to references, such as loss of the lamellar structure and size and distribution of lignin aggregates. The modification in CMLccstructure in ash TMW3 h, 220°Cis different from that of softwoods.
Structural and Magnetic Properties of Zinc and Silicon Oxides Doped Cu Ferrite for Temperature Controller Devices
Authors: Hessien M. M. , Ahmed E. M. , Hemeda O. M. 
Published: November 2014

Abstract
The effects of Si+4 and Zn+2 substitutions on the structural and magnetic properties of Cu1−xZnx+ySiyFe2−2yO4 ferrites prepared by double sintering ceramic technique have been investigated. From X-ray diffraction analysis, it was found that substitution of Zn and Si enhanced sintering process and crystallization. The XRD peaks increase by increasing Zn and Si content. On the other hand, the initial permeability decreases sharply at Curie temperature for all samples, which makes Zn/Si co-doped CuFe2O4 spinel ferrites a very promising candidate for magnetic switches, magnetic temperature transducers (MTT), and for fabrication of temperature sensitive controller devices. The important change of Curie temperature of CuFe2O4 compound occurs by simply controlling the content of Zn and Si within CuFe2O4 and results in obtaining magnetic materials with desired Curie temperature. Magnetic hysteresis loop measurements show that the samples have soft magnetic character.

Abstract

Background: Stephania abyssinica (Dillon & A. Rich) Walp (Menispermaceae) is a medicinal plant used in the west region of Cameroon to treat arterial hypertension. The present study evaluated the vasorelaxant effects of the aqueous (AESA) and methanol (MESA) extracts from the fresh leaves of S. abyssinica on aorta rings isolated from Wistar rats.

Methods: Aorta rings with intact endothelium were contracted with KCl (60 mM) or phenylephrine (10−5 M) and exposed to cumulative concentrations of each extract, ranging from 10 to 1,000 µg/mL. The vasorelaxant effects of AESA were further evaluated in presence of Nω-nitro-L-arginine methyl ester (L-NAME, 10−4 M), tetraethylammonium (TEA, 5 µM), glibenclamide (5 µM), propranolol (5 µM), and the association glibenclamide–propranolol (AGP). In another set of experiments, the effect of AESA was evaluated on calcium-induced contraction in a hyperpotassic milieu.

Results: AESA and MESA exhibited a concentration-dependent vasorelaxation on KCl-contracted aortic rings with respective EC50 of 160.10 and 346.50 µg/mL. AESA similarly relaxed aortic rings contracted with phenylephrine (EC50, 176.80 µg/mL). The vasorelaxant activity of AESA was not significantly affected by L-NAME but was markedly reduced by TEA, glibenclamide, propranolol, and AGP. AESA strongly inhibited the Ca2+-induced contraction by 95%.

Conclusions: These results support the use of S. abyssinica against arterial hypertension and suggest that the vasorelaxant effect of AESA is not mediated via the endothelium/nitric oxide pathway. AESA relaxant properties might be due to an inhibition of Ca2+ influx and/or the activation of ATP-sensitive K+ channels probably via the stimulation of β-adrenergic receptors.
Enhancing the Security of Cloud Manufacturing by Restricting Resource Access

Published: November 2014

Abstract
Cloud manufacturing has recently become a hot research topic in the manufacturing industry. One of the key bottlenecks that hinders the development and application of cloud manufacturing is security. As the adoption and use of manufacturing cloud depends on its security mechanism to a large extent, we propose a new resource security method to enhance the security of cloud manufacturing services by providing resources exclusive access to cloud virtual machine and restricting cloud access from unauthorized users. To enable authorized users in the right location, right time and right network to access resources, a GeoAuthentication model that maps geographic location, access time, and subnetwork information into a secret key is proposed. We also propose conflict firewall in manufacturing cloud to separate users with conflict of interest.

Published: November 2014

AbstractTo clarify the incidence of uterine fundal pressure at delivery and its effect on uterine rupture.A questionnaire was sent to 2518 institutions in Japan. We received a response from 1430.Of reporting institutions, 89.4% used fundal pressure in at least some of their deliveries. Among the 347,771 women who delivered vaginally in this study, 38,973 (11.2%) were delivered with the assistance of fundal pressure. There were six cases of uterine rupture associated with uterine fundal pressure, with one case resulting in maternal death secondary to amniotic fluid embolism.Since uterine fundal pressure may potentially cause serious injury to either the mother and/or neonates, the indications for application need to be clearly elucidated, and obstetric care providers also need comprehensive education and training.

Published: November 2014

Abstract
Based on the pivotal trial showing no clinicallyrelevant
differences between pegylated interferon α-2b
(Peg-α-2b) and α-2a (Peg-α-2a) combined with ribavirin
for treatment of chronic hepatitis C virus (HCV) genotype
1 infection in Ukraine, a cost-minimization analysis was
performed using a 1 year time horizon and both a health
care and patients’ perspective. A decision tree reflects
treatment pathways. Drug costs were based on drug labeling
and adjusted to the average body mass in Ukraine.
Subgroup analysis was applied to deal with heterogeneity
of patient’s weight causing dose changes. A break-even
price of Peg-α-2a and Peg-α-2b (based on the average dose)
was calculated. Univariate sensitivity analyses and probabilistic
sensitivity analysis were carried out to reflect
decision uncertainty. For an average body weight, total
medical costs per patient differ from US$9220 for Peg-α-2b
to US$9513 for Peg-α-2a from a health care perspective, and
from US$15,212 to US$15,696 from a patients’ perspective. Sensitivity analyses show these results are robust. With
average body weight, the break-even price of Peg-α-2b may
be 7.3% higher than Peg-α-2a to have similar total costs.

Published: November 2014

Abstract
Background. Many recent studies revealed that
the single nucleotide polymorphisms have considerable
effects on the susceptibility of cancer, such as prostate
cancer, lung cancer and gastric cancer. The E-cadherin, a
calcium-dependent transmembrane glycoprotein encoded
by CDH1 gene, is critical for epithelial construction, intercellular
adhesion and cell migration. Some associations
have been reported between single nucleotide polymorphisms
and gastric cancer in the Chinese population.
Objective. To investigate whether the single nucleotide
polymorphism in CDH1 gene is associated with the susceptibility
of gastric cancer in the Chinese population.
Material and methods. The genotypes of 5 known single
nucleotide polymorphisms (rs33935154, rs121964871,
rs121964874, rs121964875, rs121964876) were determined in 359 gastric cancer patients and 368 healthy controls.
High resolution melting curve detection and sequencing
analysis were used in the present study. Results. There
is a statistical significance in the rs121964871 C>G polymorphism
between gastric cancer patients and healthy
controls (OR=1.769, 95%CI: 1.051-2.976). Elderly male individuals
(>50 years of age) carrying this risk factor may
be more susceptible to gastric cancer. Conclusions. The
results indicated that the rs121964871 C>G polymorphism
is associated with the susceptibility of gastric cancer in
the Chinese population, with some age and sex-dependent
tendencies observed.
Submental epidermoid cysts in children
Authors: Zielinski Rafal , Zakrzewska Anna 
Published: November 2014

Abstract
Epidermoid cysts are lesions, which form as a
result of implantation of the epidermis in the layers of the
dermis or the mucous membrane. The lesions are rare in
adults with 7% occurring in the head and neck area and
most often located in the submental region. In children
population submental epidermoid cysts are extremely
rare. The differential diagnosis of the lesions is necessary
as it affects the choice of treatment methods. Among the
pathological conditions occurring in that region, salivary
retention cyst (ranula), thyroglossal duct cyst, vascular
lymphatic malformation (cystic hygroma), median neck
cyst, lymphadenopathy, thyroid gland tumor, laryngeal
cyst, epidermoid and dermoid cysts, submental abscess,
sialolithiasis and salivary gland inflammation should be
considered. The authors of the present report demonstrate
two cases of submental epidermoid cysts in children.
Differential diagnosis in case of suspected submental epidermoid
cyst in a child with proposed clinical practice
and literature review is provided.

Published: November 2014

AbstractA case of renal arteriovenous fistula between the main renal artery and interlobar vein diagnosed 25 years after percutaneous renal biopsy was presented. A 62-year-old female was referred to a urologist with dilatation of the left renal pyelocalyceal system diagnosed after abdominal ultrasonography, while intravenous urography did not confirm that finding. Historically, she underwent renal biopsy 25 years ago without any complication. Her hypertension was well controlled during the last 10 years, although three antihypertensive drugs with occasional additional diuretics were necessary during the last 6 months. Color Duplex Ultrasonography, arteriography and Multi-Slice Computed Tomography revealed the presence of renal arteriovenous fistula between the main renal artery and interlobar vein, as well as severe dilatation of all interlobar veins, renal, ovarian and adrenal vein on the left side. Urological and vascular surgeons operated to ligate the fistula and preserve the kidney. However, it was not possible to reach the fistula inside the kidney and nephrectomy was performed.
“We”, “They” and the Spaces In-Between: Hybridity in Intercultural Interactions between Portuguese and Chinese Residents in Macau
Authors: Amaro Vanessa 
Published: November 2014

AbstractThis study seeks to explore the hybrid cultural and linguistic spaces that Portuguese immigrants create in Macau in the process of engaging in intercultural communication with the Chinese local community. I use critical discourse analysis to examine data collected through in-depth interviews and observations in order to arrive at an understanding and provide an explanation of how Portuguese residents in Macau negotiate their interactions with the Chinese host culture. In these interviews participants furnish accounts of how they preserve their own cultural and linguistic space, while at the same time achieving functional integration in Macau when interacting with the Chinese population. Using hybridity as the theoretical framework, my research shows how participants deal with living and communicating within and between two distinct cultures; it also demonstrates how their lack of literacy in Cantonese limits the degree and form of integration that they are able to achieve.
The NPU format for clinical laboratory science reports regarding properties, units, and symbols (IUPAC Technical Report)
Authors: Férard Georges , Dybkaer René 
Published: November 2014

Abstract
The terminology of NPU (nomenclature for properties and units) aims at describing properties examined in clinical laboratories for a patient. It was originally jointly approved in 1966 by IUPAC and by the International Federation of Clinical Chemistry (IFCC) and covers multiple disciplines in the field of clinical laboratory sciences, including clinical allergology, clinical chemistry, clinical haematology, clinical immunology and blood banking, clinical microbiology, clinical pharmacology, molecular biology and genetics, reproduction and fertility, thrombosis and haemostasis, and toxicology. The NPU terminology adheres to international standards of metrology and of terminology, in particular the International System of Quantities (ISQ) and International System of Units (SI), the International Vocabulary of Metrology (VIM), and also to ‘An outline for a vocabulary of nominal properties and examinations – basic and general concepts and associated terms,’ recently prepared on behalf of the IFCC-IUPAC Committee-Subcommittee on Nomenclature for Properties and Units. The present document recalls the definitions of the concepts used to express a property of a patient, regarded as a system. The aim is to promote by this comprehensive summary the proper NPU terminology for reliable exchange of patient examination data. The use of this syntax and of SI units enables the translation of these descriptions into other languages without loss of meaning or accuracy. The NPU format is also well adapted for comparative and epidemiological studies. More information will be found in the upcoming 2nd edition of the Compendium of Terminology and Nomenclature of Properties in Clinical Laboratory Sciences, the IUPAC and IFCC ‘Silver Book’, and in the recently published ‘Properties and units in the clinical laboratory sciences. Part XXIII. The NPU terminology, principles, and implementation: A user’s guide (IUPAC Technical Report)’ (DOI:10.1351/PAC-REP-11-05-03).
Environmental dependence of stellar velocity dispersion in the Main galaxy sample of SDSS DR10
Authors: Deng Xin-Fa 
Published: November 2014

Abstract
The aim of this work is to examine the environmental
dependence of stellar velocity dispersion in local
galaxies. In studies that likely suffer from the radial selection
effect, one has a preference for the use of volumelimited
samples. Two volume-limited samples with different
redshift and luminosity ranges were constructed from
the Main galaxy data of the Sloan Digital Sky Survey Data
Release 10 (SDSS DR10). Considering some drawbacks of
volume-limited samples, the apparent magnitude-limited
Main galaxy sample was also applied. Statistical analyses
in these different galaxy samples can reach the same conclusion:
galaxies with large stellar velocity dispersions exist
preferentially in high density regimes, while galaxies
with small stellar velocity dispersions are located preferentially
in low density regions, which is inconsistent with
that obtained at intermediate redshifts.

Abstract
As part of the studies on the development of alternate extractants for fast reactor fuel reprocessing, a mixer-settler facility for
performing counter-current solvent extraction runs with radioactive materials has been set up and commissioned in our laboratory for
flow sheet development experiments. Mixer-settler runs were carried out with 1.1 M TiAP/Heavy Normal Paraffin (HNP) as the
solvent using the above facility to test the equipment as well as the behaviour of the solvent for continuous solvent extraction
processes. Stage profile data generated for the extraction and stripping of nitric acid with TiAP based solvent have been
reported. Studies carried out on the continuous counter-current extraction and stripping of U(VI) for 1.1 M
TiAP/HNP-U(VI)-HNO3 system under high solvent loading conditions are also reported in this paper. Overall and stage-wise mass
balance data for the above runs are also discussed.

Abstract
A typical problem in low-level liquid scintillation (LS) counting is the identification of α particles in the presence of
a high background of β and γ particles. Especially the occurrence of β-β and β-γ pile-ups may
prevent the unambiguous identification of an α signal by commonly used analog electronics. In this case, pulse-shape
discrimination (PSD) and pile-up rejection (PUR) units show an insufficient performance. This problem was also observed in own earlier
experiments on the chemical behaviour of transactinide elements using the liquid-liquid extraction system SISAK in combination with
LS counting. α-particle signals from the decay of the transactinides could not be unambiguously assigned. However, the
availability of instruments for the digital recording of LS pulses changes the situation and provides possibilities for new
approaches in the treatment of LS pulse shapes. In a SISAK experiment performed at PSI, Villigen, a fast transient recorder, a PC card
with oscilloscope characteristics and a sampling rate of 1 giga samples s−1 (1 ns per point), was used for the first
time to record LS signals. It turned out, that the recorded signals were predominantly α, β-β and β-γ pile up, and fission events. This paper describes the subsequent development and use of artificial neural networks (ANN) based on the
method of “back-propagation of errors” to automatically distinguish between different pulse shapes. Such networks can “learn”
pulse shapes and classify hitherto unknown pulses correctly after a learning period. The results show that ANN in combination with fast
digital recording of pulse shapes can be a powerful tool in LS spectrometry even at high background count rates.

Published: November 2014

Abstract
The benefits of lowering the operation temperature of solid oxide fuel cells (SOFCs) have attracted great attention worldwide. There has been an enormous effort in the literature for the improvement of the electrolyte materials working at lower temperatures. The family of BiMeVOx (Bi–bismuth, Me–dopant metal, V–vanadium, Ox–oxide) materials has been found to have specific properties as oxide ion conductor (electrolyte) for low operation temperature. These materials exhibit uniquely structural features rather different from those of other solid electrolytes. It is possible to use these as the electrolyte in SOFCs. This article attempts to review the main structural and electrochemical characteristics of BiMeVOx materials in order to show a guideline for designing novel BiMeVOx-based electrolyte for low-temperature SOFCs. The prospects and challenges for the application of these materials as the electrolyte are discussed.
Initial and final fracture behaviors of woven fabric composites
Authors: Demircan Ozgur 
Published: November 2014

AbstractWithin the scope of the experiments, the initial and final fracture behaviors in glass roving and glass cloth composites were investigated. After the production of two types of composite panels with the hand lay-up method, tensile and three-point bending tests on composites were conducted. Acoustic emission (AE) and optical microscopy (cross-sectional observation) analyses based on the various strain rates in bending tests were performed to see the fracture initiation and propagation in composites. The initial fractures were transverse cracks in the glass roving composites; these were delaminations in glass cloth composites. The final fractures were transverse cracks, delaminations, and fiber breakages in glass roving and glass cloth composites. In this study, the fracture process and mechanisms of glass roving and glass cloth composites were successfully identified by AE characteristics and cross-sectional observations.
Multi-voiced assessment in a mental health final statement
Authors: Günther Kirsi 
Published: November 2014

AbstractThe focus of this article is on the records written during an intensive assessment and rehabilitation course targeted at young adults suffering from severe mental health issues. The ability of the clients to cope with everyday life is assessed during the rehabilitation course and the final statement compiled by the keyworker includes the combined results of the assessments of each client. Using intertextual analysis, I examine these final statements and utilize the concepts of voice and direct and indirect reported speech. I ask how and what kinds of voices are used in final statement to assess the clients’ progress during the course and to define the future development tasks for them. Firstly, it is shown that the final statements are multi-voiced texts. They are persuasive statements about the clients’ development stories and descriptions of how the rehabilitation course practitioners have helped the client. Secondly, the analysis shows how voice and client knowledge are present in the final statement. The voices of assessment build the argument dialogically and highlight temporality, and in this way they produce a convincing description of the mental health client’s current ability to function and progress on the rehabilitation course.
