AbstractStaphylococcus aureusstrains were isolated from mastitic milk of cows with infected mammary glands. The animals were living in 12 different farms near Lublin, in Central-Eastern Poland. A biochemical identification method based on enzymatic assay was performed, followed by haemolytic and proteolytic tests. PCR-RFLP targeted on thegapgene allowed the genetic identification of strains at the species level and verified phenotypic identification results. A molecular typing method using triplex PCR was performed to recognize the genetic similarity of the analyzed strains. DNA microarray hybridization (StaphyType, Alere Technologies) was used for detection of antibiotic resistance and virulence associated markers. The results obtained indicate high genetic similarity in strains isolated from the same sites. High genetic similarities were also detected between strains isolated from cows from different farms of the same region. A slightly lower similarity was noted however, in strains from various regions indicating that the strains are herd specific and that the cow’s infections caused byS. aureuswere of a clonal character. In 21 representative isolates selected for DNA-microarray testing, only fosfomycin (fosB) and penicillin resistance markers (blaZ, blaI, blaR) were detected. The presence of genes coding for haemolysins (lukF, lukS, hlgA, hla, hld, hlb), proteases (aur, sspA, sspB, sspP), enterotoxins (entA, entD, entG, entI, entJ, entM, entN, entO, entR, entU, egc-cluster), adhesins (icaA, icaC, icaD, bbp, clfA, clfB, fib, fnbA, map, vwb) or immune evasion proteins (scn, chp, sak) was common and, with exceptions, matched triplex PCR-defined clusters.

AbstractThe aim of this study was to determine the effectiveness of low-level laser therapy (LLLT) on the modulation of the systemic inflammatory processes and skeletal muscle morphology in an experimental sepsis model (cecal ligation and puncture, CLP).Seventy-two male Wistar rats were randomly divided into three groups: control group (CG); sepsis group (SG) where rats were submitted to CLP but without LLLT treatment, and the sepsis laser-treated group (SLG). Laser irradiation (GaAlAs laser, continuous wave, 808 nm, 30 mW, 48 s, 30 J/cmThe results showed that the laser-treated animals presented a lower IL-6 activity and decreased atrogin and MuRF-1 immunoexpression. However, no difference was observed in muscle cross-sectional area between the experimental groups.These results suggest that LLLT was able to decrease the systemic inflammation and muscle atrophy markers, preventing muscle protein degradation.

Abstract
This study evaluated the spatial distribution of two environmentally relevant radionuclides, 137Cs and 40K, in
marine superficial sediments around the Angra Nuclear Power Plant, the only Brazilian nuclear power plant complex, thus establishing
a baseline for bottom sediments, given the international importance of environmental monitoring around nuclear facilities. It was
observed that these radionuclides are mostly present in the muddy sediments as a result of their stronger association with its
fine-grained fraction, and that their lowest levels are located around the liquid effluent discharge of the plant, as a consequence of
the prevented deposition of fine sediments due to the strong discharge water flux. The comparison of the 137Cs activities
in the region with other locations in the world showed that the presence of this artificial nuclide is due to the atmospheric fallout
from past nuclear tests made during the Cold War, not to the nuclear power plant activities.

Authors: Pathak Pranav D. , Mandavgane Sachin A. , Kulkarni Bhaskar D. 
Published: July 2015

AbstractFruit peel waste (FPW) is abundantly available from the agricultural and food processing industry and has been studied in recent past as an adsorbent. This paper critically reviews the reported work and investigates various FPW-pollutant systems. The study includes statistics of FPW generation, modification, characterization, adsorption ability, recovery/regeneration, and modeling (isotherms, kinetics, and thermodynamics) of batch adsorption. It is found that orange and banana peels are the most extensively studied adsorbents, whereas Pb
Exact likelihood-free Markov chain Monte Carlo for elliptically contoured distributions
Authors: Muchmore Patrick , Marjoram Paul 
Published: July 2015

AbstractRecent results in Markov chain Monte Carlo (MCMC) show that a chain based on an unbiased estimator of the likelihood can have a stationary distribution identical to that of a chain based on exact likelihood calculations. In this paper we develop such an estimator for elliptically contoured distributions, a large family of distributions that includes and generalizes the multivariate normal. We then show how this estimator, combined with pseudorandom realizations of an elliptically contoured distribution, can be used to run MCMC in a way that replicates the stationary distribution of a likelihood based chain, but does not require explicit likelihood calculations. Because many elliptically contoured distributions do not have closed form densities, our simulation based approach enables exact MCMC based inference in a range of cases where previously it was impossible.
Plastic flow rule for sands with friction, dilation, density and stress state coupling
Authors: Wojciechowski Marek 
Published: July 2015

Abstract
In this paper we propose a flow rule and failure criterion for sands in plane strain conditions based on Drucker-Prager formulation and enhanced with empirical Houlsby formula, which couples friction, dilation, density and stress state in the material. The resulting elasto-plastic, non-associated, shear hardening material model is implemented as a numerical procedure in the frame of finite element method and a simple compression example is presented. Because of the empirical nature of Houlsby formula, it is believed that results of numerical simulations will be more realistic both in deformation and shear strength estimation of sands.
Determinants Of Savings Behavior In Pakistan: Long Run - Short Run Association And Causality
Authors: Ahmad Fawad 
Published: July 2015

AbstractThe existing studies on private savings have mostly investigated the long run and short association of different variables with private savings, whereas no known study has investigated both long run and short run causality of variables against private savings by using data of Pakistan. The current study used time series data of Pakistan over the period of 1972 to 2012 and employed long run cointegration test, first normalized equation for long run association, vector error correction model for short run association, Toda Yamamoto technique for long run causality and Granger causality test for short run causality. The results suggest that GDP per capita, inflation rate, financial development, dependency ratio and fiscal development have impact on the private savings rate in Pakistan. The findings of the current study can be used to increase the private savings’ rate. In the long run government can increase the private savings by controlling fiscal deficit and promoting the investment by private investors. Whereas, in the short run, government can increase the deposit rate to increase the private savings. The current study is unique in its nature as it simultaneously provides the long run and short run causality and association and can contribute significantly in improving savings rate in developing economies like Pakistan.
Optimization of a Turboprop UAV for Maximum Loiter and Specific Power Using Genetic Algorithm
Authors: Dinc Ali 
Published: July 2015

AbstractIn this study, a genuine code was developed for optimization of selected parameters of a turboprop engine for an unmanned aerial vehicle (UAV) by employing elitist genetic algorithm. First, preliminary sizing of a UAV and its turboprop engine was done, by the code in a given mission profile. Secondly, single and multi-objective optimization were done for selected engine parameters to maximize loiter duration of UAV or specific power of engine or both. In single objective optimization, as first case, UAV loiter time was improved with an increase of 17.5% from baseline in given boundaries or constraints of compressor pressure ratio and burner exit temperature. In second case, specific power was enhanced by 12.3% from baseline. In multi-objective optimization case, where previous two objectives are considered together, loiter time and specific power were increased by 14.2% and 9.7% from baseline respectively, for the same constraints.

Topologically, if each CNA anion is regarded as a linker, and each Cd(II) atom considered as a 4-conencted node, the structure is simplified as a 4-connected (4,4) network. The solid state photoluminescent properties of the compound were also studied at room temperature.
Challenging High-Level ab initio Rovibrational Spectroscopy: The Nitrous Oxide Molecule
Authors: Schröder Benjamin , Sebald Peter , Stein Christopher , Weser Oskar , Botschwina Peter 
Published: July 2015

Abstract
The equilibrium structure and rovibrational energies of nitrous oxide
(N2O) in its electronic ground state (X
1
Σ
+) are
derived from a high-level ab initio potential energy function
(PEF). This PEF is based on a composite approach with the basic
contribution given by explicitly correlated coupled-cluster (CC)
calculations. Smaller contributions include corrections due to
inner-shell correlation, scalar-relativistic effects and higher-order
correlation up to iterative pentuple excitations (CCSDTQP in CC
nomenclature). The high importance of higher-order correlation in
order to reach the desired accuracy led to the use of an extrapolation
scheme to approximately account for the effect of hextuple and some
pentuple excitations. A reasoning for the soundness of the method is
given in this work. The results of the rovibrational calculations are
compared to those of two multi-reference (MR) based composite PEFs,
where the basic contribution is given by MR configuration interaction
and MR average coupled-pair functional calculations. A highly accurate
electric dipole moment function is also computed by the three
composite methods in excellent agreement with the experimental values
available. Subtle irregularities in the intensity pattern are
reproduced in great detail and several kinds of resonances are
analyzed without the need to empirically adjust our best ab
initio PEF. The equilibrium bond lengths were determined by a mixed
experimental/theoretical approach yielding
R
e(NN) = 1.12695(10) Å and
R
e(NO) = 1.18539(5) Å.
Severe hypercalcemia and hypernatremia in a patient treated with canagliflozin
Authors: Kaur Arshpreet , Winters Stephen J 
Published: July 2015

Summary
Drugs that inhibit the sodium-glucose co-transporter-2 (SGLT2) are an exciting novel, insulin-independent treatment for diabetes that block glucose reabsorption from the proximal tubules of the kidney, leading to increased glucose excretion and lower blood glucose levels. Inhibition of SGLT2 activity also reduces sodium reabsorption, which together with glycosuria produces a mild diuretic effect with the potential for dehydration and hyperkalemia. We report on a 60-year-old man with uncontrolled type 2 diabetes treated with insulin, glimepiride, metformin and canagliflozin, who was admitted with altered mental status after a syncopal episode. He had a 1-week history of ingestion of Tums for heartburn followed by poor appetite and lethargy. Laboratory work-up showed acute kidney injury, diabetic ketoacidosis (DKA), and parathyroid hormone-independent severe hypercalcemia of 17.4 mg/dl. DKA resolved with insulin treatment, and saline hydration led to improvement in hypercalcemia and renal function over 48 h, but was accompanied by a rapid increase in the serum sodium concentration from 129 to 162 mmol/l despite changing fluids to 0.45% saline. Urine studies were consistent with osmotic diuresis. Hypernatremia was slowly corrected with hypotonic fluids, with improvement in his mental status over the next 2 days. This is the first report of hypercalcemia associated with the use of a SLGT2 inhibitor. Although the exact mechanism is unknown, canagliflozin may predispose to hypercalcemia in patients ingesting excessive calcium because of dehydration from osmotic diuresis, with reduced calcium excretion and possible increased intestinal calcium absorption. Saline therapy and osmotic diuresis may lead to hypernatremia from electrolyte-free water loss.

Learning points

Canagliflozin, an SGLT2 inhibitor, may cause hypercalcemia in susceptible patients.

Although the exact mechanisms are unknown, dehydration from osmotic diuresis and increased intestinal calcium absorption play a role.

Close monitoring of serum calcium levels is recommended in patients treated with SGLT2 inhibitors who are elderly, have established hypercalcemia, or take oral calcium supplements.

Saline therapy and osmotic diuresis may lead to hypernatremia from electrolyte-free water loss in susceptible patients.

Published: July 2015

BACKGROUND:
Hospital quality-of-care measures are publicly reported to inform consumer choice and stimulate quality improvement. The number of hospitals and states with enough pediatric hospital discharges to detect worse-than-average inpatient care remains unknown.

METHODS:
This study was a retrospective analysis of hospital discharges for children aged 0 to 17 years from 3974 hospitals in 44 states in the 2009 Kids’ Inpatient Database. For 11 measures of all-condition or condition-specific quality, we assessed the number of hospitals and states that met a “power standard” of 80% power for a 5% level significance test to detect when care is 20% worse than average over a 3-year period. For this assessment, we approximated volume as 3 times actual 2009 admission volumes.

RESULTS:
For all-condition quality, 1380 hospitals (87% of all pediatric discharges) and all states met the power standard for the family experience-of-care measure; 1958 hospitals (95% of discharges) and all states met the standard for adverse drug events. For condition-specific quality measures of asthma, birth, and mental health, 203 to 482 hospitals (52%–90% of condition-specific discharges) met the power standard and 40 to 44 states met the standard. One hospital and 16 states met the standard for sickle cell disease. No hospital and ≤27 states met the standard for the remaining measures studied (appendectomy, cerebrospinal fluid shunt surgery, gastroenteritis, heart surgery, and seizure).

CONCLUSIONS:
Most children are admitted to hospitals in which all-condition measures of quality have adequate power to show modest differences in performance from average, but most condition-specific measures do not. Policies regarding incentives for pediatric inpatient quality should take these findings into account.
The Impact of Media on Students’ Perception of the Security Risks Associated With Internet Social Networking - A Case Study / Utjecaj medija na percepciju sigurnosnih rizika povezanih s društvenim umrežavanjem putem interneta – studija slučaja

Published: July 2015

AbstractFrom the viewpoint of cybercrime, young people represent a particularly vulnerable category of Internet users: children, adolescents and students. Young people are, undoubtedly, the most common and the most gullible users of social networks. Due to lack of education related to dangers they are exposed to on social networks, inexperienced users recklessly post information and multimedia contents on their profiles which can be misused by differently motivated Internet users. Apart from being exposed to the risk from the violation of personal privacy and misuse of personal data, young people are exposed to the risk from political or ideological manipulation. Various studies on social networks and secondary school students have been conducted in the Republic of Serbia. However, no study in this field which would look at university students has yet been conducted. The purpose of this study was to discover the extent to which students use social networking sites, but also the sources and ways students perceive online security risks associated with social networking. Study results show that the media has a dominant role in educating young people on the risks associated with social networking and that the impact of the media is greater than the impact of other educational factors such as family, school or university. Key words: media; security impact; social networks.---SažetakS gledišta kibernetičkoga kriminaliteta mladi ljudi (djeca, adolescenti i studenti) predstavljaju osobito ranjivu skupinu korisnika interneta. Mladi su ljudi, bez sumnje, najčešći i najlakovjerniji korisnici društvenih mreža. Zbog nedostatka edukacije o opasnostima kojima su izloženi na društvenim mrežama, neiskusni korisnici na svojim profilima nesmotreno objavljuju informacije i multimedijske sadržaje koje mogu upotrijebiti korisnici interneta koji imaju drugačije motive. Osim što su izloženi riziku kršenja osobne privatnosti i zlouporabe osobnih podataka, mladi se ljudi izlažu mogućoj političkoj i ideološkoj manipulaciji. U Republici Srbiji provedene su razne studije o društvenim mrežama i srednjoškolcima, no ni jedna od tih studija nije za ciljnu skupinu imala studente. Svrha ovoga istraživanja bila je ustanoviti do koje se mjere studenti koriste društvenim mrežama na internetu i utvrditi izvore putem kojih se informiraju o sigurnosnim rizicima vezanim uz društveno umrežavanje. Rezultati istraživanja pokazuju da mediji imaju dominantnu ulogu u upoznavanju mladih ljudi s rizicima vezanim uz društveno umrežavanje. Utjecaj medija veći je od utjecaja ostalih odgojno-obrazovnih čimbenika kao što su obitelj, škola ili fakultet. Ključne riječi: društvene mreže; mediji; sigurnosni utjecaj.
Reclamos de autodesignación identitaria a través del espejo mediático
Authors: Martínez Suárez Yolanda , De Salvador Agra Saleta 
Published: July 2015

With Alice, in Through the Looking Glass, we analyzed the construction of identities from the binomial self-designation - hetero-designation, based on the dual logic in which the identity configuration is inserted and we examined the access to the media and the public sphere. The leap to self-designation involves the transit from the object to the subject, the reformulation of the “space of equals” and the elimination of “ identical space”. The Web offers new opportunities for recognition and self-designation. In that sense, with Alice, we analyze the mediatic “forest” that lies across the screens, to glimpse which space is reserved for the marked minority groups, to see how the media tribunal appoints or allows them to be appointed.
