Best Constants for Moser-Trudinger Inequalities on High Dimensional Hyperbolic Spaces
Authors: Lu Guozhen , Tang Hanli 
Published: March 2016

Abstract
Though there have been extensive works on best constants for Moser-Trudinger inequalities in Euclidean spaces, Heisenberg groups or compact Riemannian manifolds, much less is known for sharp constants for the Moser-Trudinger inequalities on hyperbolic spaces. Earlier works only include the sharp constant for the Moser-Trudinger inequality on the twodimensional hyperbolic disc. In this paper, we establish best constants for several types of Moser-Trudinger inequalities on high dimensional hyperbolic spaces ℍn (n ≥ 2). These include sharp constants for the Moser-Trudinger inequalities on both bounded and unbounded domains of the hyperbolic space ℍn (see Theorems 1.1 and 1.2), sharp constants for the singular Moser-Trudinger inequality on unbounded domains when we impose restrictions only on the gradient norms (Theorem 1.3) or on the full hyperbolic Sobolev norms (Theorem 1.4). Our results are surprisingly general and extend most results in Euclidean spaces to hyperbolic spaces of any dimension. In particular, we have used a rearrangement-free argument in the hyperbolic spaces to establish Theorems 1.3 and 1.4 where symmetrization argument does not work to prove such sharp singular Moser-Trudinger inequalities on the entire hyperbolic space.

Published: March 2016

Abstract
Accommodating frequent product changes in a short period of time is
a challenging task due to limitations of the contemporary engineering
approach to design, build and reconfigure automation systems. In
particular, the growing quantity and diversity of manufacturing
information, and the increasing need to exchange and reuse this
information in an efficient way has become a bottleneck. To improve
the engineering process, digital manufacturing and Product, Process
and Resource (PPR) modelling are considered very promising to compress
development time and engineering cost by enabling efficient design and
reconfiguration of manufacturing resources. However, due to
ineffective coupling of PPR data, design and reconfiguration of
assembly systems are still challenging tasks due to the dependency on
the knowledge and experience of engineers. This paper presents an
approach for data models integration that can be employed for coupling
the PPR domain models for matching the requirements of products for
assembly automation. The approach presented in this paper can be used
effectively to link data models from various engineering domains and
engineering tools. For proof of concept, an example implementation of
the approach for modelling and integration of PPR for a Festo test rig
is presented as a case study.

Published: March 2016

AbstractAdequate bonding between dental veneering porcelains and non-precious metal alloys is a main factor for the long-term functionality of porcelain fused to metal restorations. Although a huge number of veneering porcelains are on the market, only few studies have reported about the role of bonding agents for the bond strength at their respective interface to cobalt-chromium (Co-Cr). The aim of this study was to compare the influence of a metal-ceramic bonding agent for Co-Cr alloys on the bond strength of metal-ceramic systems. The bond strength test was done according to ISO 9693 with additional detection of the first acoustic crack initiated signal while testing. The bonding agent had only minor effects on the bond strength of the different Co-Cr/ceramic systems. Only three of the nine studied systems showed statistically significant differences (p<0.05) upon applying the bonding agent. Scanning electron microscopy (SEM) showed cracks predominantly caused by adhesive failure. Based on this study, Co-Cr alloys veneered with porcelains with and without a bonding agent exceeded the minimum bond strength of 25 MPa required according to ISO 9693. However, if bond strength values based on acoustic signals were calculated, values below the threshold of 25 MPa could be observed. Such findings are important for failures caused by the occurrence of early cracks.

Kounis syndrome: an update on epidemiology, pathogenesis, diagnosis and therapeutic management
Authors: Kounis Nicholas G. 
Published: March 2016

AbstractKounis syndrome has been established as a hypersensitivity coronary disorder induced by various conditions, drugs, environmental exposures, foods and coronary stents. Allergic, hypersensitivity, anaphylactic and anaphylactoid reactions are associated with this syndrome. Vasospastic allergic angina, allergic myocardial infarction and stent thrombosis with occluding thrombus infiltrated by eosinophils and/or mast cells constitute are the three reported, so far, variants of this syndrome. Apart from coronary arteries, it affects the cerebral and mesenteric arteries. Its manifestations are broadening and its etiology is continuously increasing. Kounis syndrome is a ubiquitous disease which represents a magnificent natural paradigm and nature’s own experiment in a final trigger pathway implicated in cases of coronary artery spasm and plaque rupture. Kounis syndrome seems to be not a rare disease but an infrequently diagnosed clinical entity which has revealed that the same mediators released from the same inflammatory cells are also present and in acute coronary events of non allergic etiology. These cells are not only present in the culprit region before plaque erosion or rupture but they release their contents just before an actual coronary event. Therefore, awareness of etiology, epidemiology, pathogenesis and clinical manifestations seems to be important for its prognosis, diagnosis, treatment, prevention.
Perceptions from the outside in cases of gender violence. ‘What are you [the interpreter] doing here?’
Authors: Valero Garcés Carmen , Lázaro Gutiérrez Raquel 
Published: March 2016

AbstractA 2011 Gender Violence Macrosurvey carried out by the Centro de Investigaciones Sociológicas (CIS, Spanish Centre for Sociological Research) in collaboration with the Spanish Government warns that “the prevalence of gender-based violence amongst foreign women is twice that of Spanish women.” The problem gets worse when these women do not speak the contact language, in this case Spanish. The efforts of the Spanish Administration and the information and support provided to every gender violence victim hardly ever reach foreign victims, who essentially need the assistance of interpreters. When the presence of qualified interpreters (or interpreters at all) is not guaranteed, this may lead to inadequate, inaccurate and inefficient communication. The main purpose of this paper is to present the results of a survey conducted in 2013 amongst the main agents involved in the communication process with foreign victims of gender violence who do not speak Spanish or co-official languages. The sample size is about 600 answers by agents distributed in four fields (police, legal, health, welfare) with the majority of respondents from the police. The survey includes questions about how communication problems without an interpreter are solved, which protocol – if any – is followed to seek the assistance of an interpreter, how often they use interpreters, what problems they have experienced working with them and what they think is the interpreters’ role as well as what strategies or specific knowledge interpreters may have.

Abstract
The sexually dimorphic organization in perinatal rat brain is influenced by steroid hormones. Exposure to high levels of estrogen or endocrine-disrupting compounds during perinatal period may perturb this process, resulting in compromised reproductive physiology and behavior as observed in adult In our recent observation neonatal exposure of the female rats to estradiol-17β resulted in down-regulation of TNF-α, up-regulation of COX-2 and increase in SDN-POA size in pre-optic area in the adulthood. It is known that the control of reproductive performance in female involves a complex interplay of the hypothalamus, pituitary, and ovary. The present study was undertaken to understand the possible molecular mechanism involved in changes observed in the ovarian morphology and expression of selected genes in the ovary. Administration of estradiol-17β (100 μg) on day 2 and 3 after birth revealed up-regulation of ER-α, ER-β, COX-2 and down-regulation of TNF-α expression. Also the decrease in the ovarian weight, altered ovarian morphology and changes in the 2D protein profiles were also seen. This is apparently the first report documenting that neonatal estradiol exposure modulates TNF-α and COX-2 expression in the ovary as seen during adult stage. Our results permit us to suggest that cues originating from the modified brain structure due to neonatal exposure of estradiol-17β remodel the ovary at the molecular level in such a way that there is a disharmony in the reproductive function during adulthood and these changes are perennial and can lead to infertility and changes of reproductive behavior.

AbstractThe frog skin host-defense peptide tigerinin-1R stimulates insulin releasein vitroand improves glucose tolerance and insulin sensitivity in animal models of type 2 diabetes. This study extends these observations by investigating the molecular mechanisms of action underlying the beneficial metabolic effects of the analogue [Arg4]tigerinin-1R in mice with diet-induced obesity, glucose intolerance and insulin resistance. The study also investigates the electrophysiological effects of the peptide on KATPand L-type Ca2+channels in BRIN-BD11 clonal β cells. Non-fasting plasma glucose and glucagon concentrations were significantly (p<0.05) decreased and plasma insulin increased by twice daily treatment with [Arg4]tigerinin-1R (75 nmol/kg body weight) for 28 days. Oral and intraperitoneal glucose tolerance were significantly (p<0.05) improved accompanied by enhanced secretion and action of insulin. The peptide blocked KATPchannels and, consistent with this, improved beta cell responses of isolated islets to a range of secretagogues. Peptide administration resulted in up-regulation of key functional genes in islets involved insulin secretion (Abcc8, Kcnj11, Cacna1candSlc2a2) and in skeletal muscle involved with insulin action (Insr, Irs1, Pdk1,Pik3ca,andSlc2a4). These observations encourage further development of tigerinin-1R analogues for the treatment of patients with type 2 diabetes.

Published: March 2016

AbstractThere is an increasing body of literature supporting universal umbilical cord blood gas analysis (UCBGA) into all maternity units. A significant impediment to UCBGA’s introduction is the perceived expense of the introduction and associated ongoing costs. Consequently, this study set out to conduct the first cost-effectiveness analysis of introducing universal UCBGA.: Analysis was based on 42,100 consecutive deliveries ≥23 weeks of gestation at a single tertiary obstetric unit. Within 4 years of UCBGA’s introduction there was a 45% reduction in term special care nursery (SCN) admissions >2499 g. Incurred costs included initial and ongoing costs associated with universal UCBGA. Averted costs were based on local diagnosis-related grouping costs for reduction in term SCN admissions. Incremental cost-effectiveness ratio (ICER) and sensitivity analysis results were reported.: Under the base-case scenario, the adoption of universal UCBGA was less costly and more effective than selective UCBGA over 4 years and resulted in saving of AU$641,532 while adverting 376 SCN admissions. Sensitivity analysis showed that UCBGA was cost-effective in 51.8%, 83.3%, 99.6% and 100% of simulations in years 1, 2, 3 and 4. These conclusions were not sensitive to wide, clinically possible variations in parameter values for neonatal intensive care unit and SCN admissions, magnitude of averted SCN admissions, cumulative delivery numbers, and SCN admission costs.Universal UCBGA is associated with significant initial and ongoing costs; however, potential averted costs (due to reduced SCN admissions) exceed incurred costs in most scenarios.
Efficient use of laboratory resources: pre-screening for urine cultures by automated urinalysis and microscopy to allow exclusion of specimens from culture workflow
Authors: Gülmez Dolunay , Hasçelik Gülşen 
Published: March 2016

Abstract

Background:
Most of the urine cultures give negative results, leading to inefficient use of resources. The aim of this study was to evaluate and optimize screening by urinalysis and urine microscopy allowing elimination from the culture workflow, and find out if it might be cost effective in Turkey.

Methods:
A total of 1511 urine specimens were evaluated. Urinalysis and automated microscopy was performed by Iris iQ200 (Iris Diagnostics, USA). Results for nitrite, leukocyte esterase (LE), white blood cell (WBC), red blood cell (RBC) and all small particles (ASP) were compared to urine culture results. Savings were calculated, in case specimens predicted to be negative were not cultured.

Results:
Microbial growth was detected in 279 (18.5%) specimens. Using the most efficient algorithm, 400 (26.5%) specimens could be excluded from the workflow, leading to three (0.2%) false negatives. Second algorithm could predict negative result for 15.7% of the specimens with a negative predictive value (NPV) of 100%, saving $562.

Conclusions:
Screening urine specimens using multiple criteria might help predicting urine culture results. Although the cost of urine culture is low in Turkey, screening might still decrease cost and workload. All the variables should be considered to achieve efficient management of resources in the healthcare system without compromising patient safety.
Groins and submerged breakwaters – new modeling and empirical experience
Authors: Ostrowski Rafał , Pruszak Zbigniew , Schönhofer Jan , Szmytkiewicz Marek 
Published: March 2016

Abstract
The relationship between the effectiveness of groins and their technical condition was studied. The supporting role of groins in artificial shore nourishment was tested using the theoretical modeling of hydrodynamic and morphodynamic processes in the nearshore zone. This modeling scheme was developed as to represent the actual coastal situation occurring on the shores of the Hel Peninsula (the Gulf of Gdańsk, the southern Baltic Sea). Based on the results of computations and the results of field observations, recommendations were prepared on the design and maintenance of groins. The second part of the paper is devoted to submerged breakwaters. The theoretical modeling of wave-current fields near the segmented submerged breakwaters led to the determination of coefficients of wave transmission and rip current velocities, which finally yielded a piece of design advice. In all numerical simulations, the Delft3D software was used.
Pine pollen grains in coastal waters of the Baltic Sea
Authors: Pawlik Magdalena , Ficek Dariusz 
Published: March 2016

Abstract
Measurements relating to a yellow deposit covering large areas of the Baltic Sea in spring are reported. Analysis of water samples showed it to be of terrestrial origin and to consist mainly of pine pollen grains. The equivalent spherical diameter (ESD) of these grains ranged from 29.1 to 78.4 μm, with a maximum between 47.7 and 56.3 μm. Surface water concentrations of pollen in the coastal zone near Ustka showed that its proportion in the total suspended particulate matter (SPM) might be as high as 30-40%. Such high surface water concentrations of hitherto neglected substances critical to water color formation can give rise to serious errors in remote measurements of water composition and properties.
Mixing of brine waste in Puck Bay (the south Baltic Sea) in the light of in-situ measurements
Authors: Robakiewicz Małgorzata 
Published: March 2016

Abstract
In the north-eastern part of Poland, the underground gas stores are being constructed by diluting salt deposits. Brine, a by-product of the technology applied, is discharged into the coastal waters of the south Baltic Sea by a system of diffusers. To assess the intensity of brine mixing in the near-field of the discharge installation, a monitoring program was carried out. The results demonstrated that under the mildly dynamic conditions of Puck Bay, the discharge of brine (saturation 250 kg m-3, discharge 300 m3 h-1) leads to salinity excess below 0.5 PSU. For parameters of a real brine discharge, the dilution coefficient estimated by formulas derived from analytical solutions, predictive models and laboratory experiments for stagnant water conditions, varied in the range of 123÷360. The dilution coefficient value estimated on the basis of measurements was 1.27÷3.72 times higher than its value obtained by the use of predictive models, while estimated by formulas obtained from laboratory experiments was in the range of 1.41÷2.26 of the dilution coefficient based on measurements.

Authors: Tsarenko Petro , Borysova Olena , Blume Yaroslav 
Published: March 2016

Abstract
A comparative study was carried out on the growth characteristics of 33 strains of 12 species belonging to genera Acutodesmus (7), Botryococcus (1), Chlorella (5), Chloroidium (2), Desmodesmus (8), Euglena (2), Monoraphidium (2), and Parachlorella (6) from the Microalgae Culture Collection of the Institute of Botany, NAS of Ukraine (IBASU-A). All high biomass-producing strains considered as promising candidates for biofuel production demonstrated active growth (high maximum cell concentration, specific growth rate and productivity). The most promising strains included Acutodesmus dimorphus IBASU-A 251, 252, Desmodesmus magnus IBASU-A 401, D. multivariabilis var. turskensis IBASU-A 398, Chlorella vulgaris IBASU-A 189, 192, and Parachlorella kessleri IBASU-A 444. Their productivity varied from 0.58 g d.w. l-1 to 1.6 g d.w. l-1 per day. In general, the cultivation of these strains is considered both as a potential bioresource of feedstock for biodiesel production and other industrial demands.
Precipitation of calcium carbonate in a shallow polymictic coastal lake: assessing the role of primary production, organic matter degradation and sediment mixing
Authors: Woszczyk Michał 
Published: March 2016

Abstract
In this paper, the genesis of carbonates in a shallow, polymictic and eutrophic coastal lake (Lake Sarbsko, Poland) is deciphered. Emphasis is placed upon the relationship between carbonate sedimentation and microbial degradation of organic matter, as well as on vertical mixing of sediments. The cycling of carbonates in the lake was investigated through the analysis of lake water chemistry (pH, Ca2+, Mg2+, alkalinity, SIcalc) and the stable carbon isotope composition of dissolved inorganic carbon and sedimentary calcite. It is shown that the calcite is precipitated within a relatively short time owing to the coincidence between the activity of photosynthesizing phytoplankton, the microbial decomposition of organic matter, and the physical mixing of lake deposits. In turn, the precipitated calcite is prone to dissolution within the sediments. The data presented in this paper can be applied to explain the processes affecting the carbonate saturation in freshwater systems and to interpret δ13C signatures in the sediments of shallow lakes.
Cyanobacterial and microalgal bioactive compounds – the role of secondary metabolites in allelopathic interactions
Authors: Żak Adam , Kosakowska Alicja 
Published: March 2016

Abstract
Secondary metabolites produced by plants, algae, bacteria and fungi may affect the growth and development of biological systems. This is a natural process which occurs worldwide and is known as allelopathy. A relatively small number of these allelopathic compounds has been identified. The majority of studies describe the inhibitory effect of investigated compounds, extracts, cell-free filtrates and living cells on other organisms, although stimulatory interactions have also been noticed. Allelopathic interactions in aquatic environments could provide a competitive advantage to some species over other primary producers. Furthermore, allelopathy occurs in all aquatic habitats and all groups of autotrophs are capable of producing and releasing allelopathically active compounds. Moreover, secondary metabolites obtained from phytoplankton could demonstrate other useful bioactive properties. This review is intended to summarize the current knowledge of allelopathic interactions between microalgae and cyanobacteria in aquatic environments, as well as to provide a brief overview of the ecological importance of these interactions and their potential practical application in different branches of industry.
