Application of Biomarkers for Risk Stratification in Patients with Atrial Fibrillation
Authors: Hijazi Ziad , Oldgren Jonas , Siegbahn Agneta , Wallentin Lars
Published: November 2016

BACKGROUND

Atrial fibrillation is the most common sustained arrhythmia and an important contributor to cardiovascular morbidity and mortality. Several strategies have been proposed for prediction of outcomes and individualization of treatments to better balance the benefits of stroke prevention and risks of bleeding during anticoagulation.

CONTENT

The availability of analytically more specific and sensitive methods to measure circulating biomarkers of cellular and organ stress and dysfunction has led to testing of their utility in several cardiovascular conditions. In patients with atrial fibrillation, biomarkers of myocardial injury (troponin) and cardiovascular stress and dysfunction (natriuretic peptides, growth differentiation factor 15), myocardial fibrosis (galectin-3), renal dysfunction (creatinine, cystatin C), inflammation (C-reactive protein, cytokines) and coagulation activity (d-dimer) have been found associated with underlying pathophysiology, clinical outcomes and effects of treatment. Measurements of these markers might therefore expand the understanding of the pathophysiology, improve risk assessment and optimize treatment in individual patients with atrial fibrillation.

Biomarkers for risk stratification have potential roles as tools for evaluation of patients with atrial fibrillation and for selection of the best treatment strategies to prevent stroke, major bleeding, and mortality.

Published: November 2016

BACKGROUND

We have previously demonstrated the utility of a rule-in/rule-out strategy for myocardial infarction (MI) using glycemic biomarkers in combination with cardiac troponin in the emergency department (ED). Given that the cost of assessing patients with possible MI in the ED is increasing, we sought to compare the health services cost of our previously identified early rule-in/rule-out approaches for MI among patients who present to the ED with symptoms suggestive of acute coronary syndrome (ACS).

METHODS

We compared the cost differences between different rule-in/rule-out strategies for MI using presentation cardiac troponin I (cTnI), high-sensitivity cTnI (hs-cTnI), high-sensitivity cardiac troponin T (hs-cTnT), glucose, and/or hemoglobin A1c (Hb A1c) in 1137 ED patients (7-day MI n = 133) as per our previously defined algorithms and compared them with the European Society of Cardiology (ESC) 0-h algorithm-cutoffs. Costs associated with each decision model were obtained from site-specific sources (length of stay) and provincial sources (Ontario Case Costing Initiative).

RESULTS

Algorithms incorporating cardiac troponin and glucose for early rule-in/rule-out were the most cost effective and clinically safest methods (i.e., ≤1 MI missed) for early decision making, with hs-cTnI and glucose yielding lower costs compared to cTnI and glucose, despite the higher price for the hs-cTnI test. The addition of Hb A1c to the algorithms increased the cost of these algorithms but did not miss any additional patients with MI. Applying the ESC 0-h algorithm-cutoffs for hs-cTnI and hs-cTnT were the most costly.

CONCLUSIONS

Rule-in/rule-out algorithms incorporating presentation glucose with high-sensitivity cardiac troponin are the safest and most cost-effective options as compared to the ESC 0-h algorithm-cutoffs.
Rapid Rule-Out of Acute Myocardial Injury Using a Single High-Sensitivity Cardiac Troponin I Measurement
Authors: Sandoval Yader , Smith Stephen W , Shah Anoop S V , Anand Atul , Chapman Andrew R , Love Sara A , Schulz Karen , Cao Jing , Mills Nicholas L , Apple Fred S
Published: November 2016

BACKGROUND

Rapid rule-out strategies using high-sensitivity cardiac troponin assays are largely supported by studies performed outside the US in selected cohorts of patients with chest pain that are atypical of US practice, and focused exclusively on ruling out acute myocardial infarction (AMI), rather than acute myocardial injury, which is more common and associated with a poor prognosis.

METHODS

Prospective, observational study of consecutive patients presenting to emergency departments [derivation (n = 1647) and validation (n = 2198) cohorts], where high-sensitivity cardiac troponin I (hs-cTnI) was measured on clinical indication. The negative predictive value (NPV) and diagnostic sensitivity of an hs-cTnI concentration <limit of detection (LoD) at presentation was determined for acute myocardial injury and for AMI or cardiac death at 30 days.

RESULTS

In patients with hs-cTnI concentrations <99th percentile at presentation, acute myocardial injury occurred in 8.3% and 11.0% in the derivation and validation cohorts, respectively. In the derivation cohort, 27% had hs-cTnI < LoD, with NPV and diagnostic sensitivity for acute myocardial injury of 99.1% (95% CI, 97.7–99.8) and 99.0% (97.5–99.7) and an NPV for AMI or cardiac death at 30 days of 99.6% (98.4–100). In the validation cohort, 22% had hs-cTnI <LoD, with an NPV and diagnostic sensitivity for acute myocardial injury of 98.8% (97.9–99.7) and 99.3% (98.7–99.8) and an NPV for AMI or cardiac death at 30 days of 99.1% (98.2–99.8).

CONCLUSIONS

A single hs-cTnI concentration <LoD rules out acute myocardial injury, regardless of etiology, with an excellent NPV and diagnostic sensitivity, and identifies patients at minimal risk of AMI or cardiac death at 30 days. ClinicalTrials.gov Identifier: NCT02060760

Published: November 2016

The paper deals with the description of the intensively blasted electric arc burning in Ar in the anode channel of the arc heater operated under various conditions. Directly measured experimental data (current, voltage, gas flow rate, power loss) characterize the operation of the device as a whole, but important parameters describing the electric arc inside (its geometry, temperature and voltage distribution) must be revealed using a mathematical model of the arc. An updated version of the model is introduced and used for analysis of two exemplary sets of measured data. The results are given in figures and commented.

Published: November 2016

Mooring ropes used in offshore oil platforms are exposed to a set of extreme environmental conditions that can be crucial to their behaviour in service. Considering the elevated mechanical demands on these ropes imposed by both the undersea environment and the station keeping of the vessel, this paper is focused on the experimental determination of the yarns fatigue behavior. In order to be able to foresee and compare their general wear rate, a diagram that correlates the force to which the specimens are submitted to the number of cycles for failure for each material is achieved. The analyzed fibers are Polyester, Aramid, Polyethylne and Liquid Crystal Polymer (henceforth quoted as PET, AR, PE and LCP, respectively), and this work followed a pattern composed by a fixed test frequency and an established maximum stress for the diagrams.
Ser ou não ser bilíngue: Os posicionamentos subjetivos de uma professora de inglês diante do Outro
Authors: Franco Arabela Vieira dos Santos Silva
Published: November 2016

As propostas da linguística para categorizar um indivíduo como bilíngue formam um espectro de possibilidades, e para torná-lo ainda mais extenso, uma abordagem psicanalítica nos oferece a possibilidade de tratarmos o tema pelo viés da singularidade, analisando como cada sujeito se inscreve discursivamente como sujeito bilíngue. Visto que me filio, aqui, ao pressuposto de que é no discurso, na relação com o Outro, que esse sujeito irá se constituir, temos que não haverá significantes que se esgotem para defini-lo como bilíngue. O corpus foi formado utilizando a metodologia dos Conversational rounds e a análise dos dizeres foi feita à luz das teorias da significação e dos quatro discursos esquematizadas por Lacan. Apresento alguns dizeres de uma professora a respeito do tema bilinguismo, destacando sua relação com a fala em língua inglesa. Pude observar giros discursivos, mas não constatei nenhum deslocamento subjetivo da professora em relação ao seu posicionamento como sujeito bilíngue, ou em relação à habilidade da fala. O principal resultado dessa pesquisa foi perceber que a definição de um sujeito bilíngue ultrapassa a singularidade de uma possível classificação para cada sujeito, uma vez que a cada giro discursivo o sujeito pode se dizer ou se colocar como sendo ou não bilíngue. Portanto, qualquer tentativa de significar o sujeito será tão evanescente quanto seus posicionamentos nos discursos. Este estudo contribui, assim, para que se considere o impossível na lida com as línguas e o modo singular como cada um lida com sua falta.

Weight is an important parameter in cattle breeding. In determining price of cattle, weight must be known accurately. If the estimation of weight is not accurate, this will cause losses for farmers. On the other hand, traditional farmers don’t have enough money to buy the expensive conventional scale. Even in cattle’s market, more common ranchers estimate cattle's weight only by their feelings. This is not only causes greater potential’s loss, but also does not have a scientific foundation. This study aims to help farmers in estimating cattle's weight. Cattle's weight can be estimated by knowing Within Cow's Breast (WCB) as described in DAHAGA formula discovered by Winoto and friends in 2015. This study aims to implement the DAHAGA formula that has accuracy until 97.9% into an android application. The application runs by using the camera to estimate the object’s height to determine real value of WCB. This calculation is performed using template matching method which compares the real object with image caught on camera. After WCB parameter known, then application will execute DAHAGA formula and issued cattle’s weight as final result. This application is expected to be an easy, inexpensive and accurate solution for farmers in estimating cattle’s weight.Keywords: Cattle, Weight, Android, Camera, Template MatchingAbstrak - Bobot merupakan parameter penting dalam peternakan.

Authors: Tzounis A. , Katsoulas N. , Ferentinos K.P. , Bartzanas T. , Kittas C.
Published: November 2016

Precision greenhouse agriculture requires several measuring points in order to have a better overview of the whole cultivation area. Climate variability within the covered area of a greenhouse can result in a non-uniform plant development and reduced productivity. Therefore, a distributed system, capable of taking multi-point measurements would be able to catch the climatic gradients in order to provide growers with a more detailed depiction of the climate at any time and early warnings of potential threats. Furthermore, the distributed monitoring can offer the appropriate inputs to more sophisticated distributed or plant-based climate control algorithms. The significant price drop in embedded computer and wireless communication chips, as well as the overall maturity of the available, low-power platforms have made the deployment of Wireless Sensor Networks increasingly attractive in modern agricultural facilities. This paper presents a Wireless Sensor Network (WSN) deployed for long periods in commercial facilities, equipped with shading screens and cooling pads placed in different directions, namely vertically to the plantation and parallel to it. The evolution of the various climate parameters in both greenhouses and the effect of the climate on the plants and the wireless communications are analyzed and presented.

Researches About the Influence of Reducing the Assimilation Surface on Number of Grains/Cob Corn at Some Maize Hybrids
Authors: David Ivona
Published: November 2016

In this work it was analyzed the influence of reducing leaves surface on the number of grains/cob corn at four maize hybrids created at The National Institute for Researches and Development Fundulea. The results show that in the phenological phase of formation of stigmata, at studied hybrids, the most important factor which influenced the number of grains/cob corn were the last three leaves under panicle. On average, leaf removal produced losses in the number of grains /cob corn compared with the control values for all variants tested. Losses ranged between 12 and 26% compared to the control variant. The most obvious reduction in the number of grains / cob corn for analyzed hybrids were recorded in the variant where the leaves are removed from the top of the corn cob and remained only the leaf under the panicle. (74 % of control). In phenological phase of 15 days after stigmata formation, the lowest value of this character was recorded in experimental version which have been removed all the leaves above the cob corn, respectively 80 % of controls, and the maximum value of the analyzed hybrids was registered in experimental version which have been removed all the leaves below the corn cob.
Facilitation Fish Migration above the Discharge Sill Located on the Ialomiţa River Near Cave Ialomicioara
Authors: Voicu Răzvan , Dominguez Lawrence G.
Published: November 2016

Longitudinal connectivity restoration of watercourses is a major duty for scientists (biologists, hydro engineers, chemists etc.) that, by the means of technical exchange via conferences, projects, workshops, universities, and institutions demonstrate the major importance of a natural (non-anthropic) function of the lotic ecosystems. On the Ialomiţa River, the discharge sills located downstream from Padina chalet block the migration of some fish species, such as the brown trout (Salmo trutta) and the bullhead (Cottus gobio), prohibiting access to foraging areas and springs. Water Framework Directive 60/2000 / EC provides a legal framework for restoring “good status” of longitudinal and lateral connectivity of watercourses. Our proposed solution I can be applied to other discharge sills and dams sized between 3m and 6m high, and, where feasible can utilize existing power sources of some discharge sills. Solution II’s concepts allow the dimples inside the concrete plate to serve as a rest and recovery area for migratory species. Such benefits that ensure upstream/downstream fish migration while allowing discharge management to continue is unattainable in conventional systems. After solution II is applied the discharge sill does not lose any baseline characteristics while maintaining the original hydro-technical design objective, flood dissipation.
Socioeconomic Valences of the Human Settlements in Tecuci Plain in the Context of Sustainable Development
Authors: Stănilă Cristian , Barbu Oana Nicoleta
Published: November 2016

In conducting the scientific endeavor we started from the assumption that directing the efforts of local communities based on the principles of sustainable development, the degree of socio-economic development of the Tecuci Plain will be improved in a time span of 25-30 years. The development of the plain is below its potential but it presents viable resources that can lead to the shaping of sustainable development strategies applicable at territorial level. The various works consulted point out that the sustainable development of an area requires a complex precede that provides the analysis of all factors which can influence human settlements’ development of perspective. In this sense it entails identifying the natural conditions of the Tecuci Plain and how they are reflected by the socio-economic development of human settlements, knowing that this space is identified at regional and national level as an important agricultural center that utilizes rationally the land. The quintessence that can accelerate the sustainable development of the territory is given by the accessibility to the local and regional context of the Tecuci Plain. Accessibility is also a prerequisite in establishing a network of centers polarizing localities that maintain functional interdependencies and diffusion of services across sectors. The knowledge of space and disorders diagnosing are absolutely necessary for integrating development policies to implement the phenomenon of territorial, social and economic cohesion. Rural settlements of the Tecuci Plain radiate around the only urban center, the city of Tecuci, center that tries to regain its identity and its importance by channeling efforts to promote agricultural products in the region, given that the secondary and tertiary sectors fail to gain ground in front of the basic occupation of 60% of the administrative units that are part of the plain. The rural component from the Tecuci Plain is actually a whole scale (system) “built” on a macro scale with three elements (subsystems): the physical subsystem (environmental and natural conditions), the social subsystem (rural population and habitat rural) and economical subsystem (external physical environment transformed by the rural population).
Phototextuality as a Phenomenon of Present-Day British Prose
Authors: Sudliankova Volha
Published: November 2016

Like many other world literatures, the English literature of the last few decades has been marked by an intensive search for new narrative techniques, for innovative ways and means of arranging a plot and portraying characters. The search has resulted, among other things, into merging literature with visual arts like painting, film and photography. This phenomenon got the name of ekphrasis and has become a popular field of literary research lately.

Suffice it to cast a glance at several of the novels published around the year 2000 to see that incorporation of photographic images into fiction allows writers to use new means of organizing literary texts, to employ non-conventional devices of structuring a plot and delineating personages as well as to pose various problems of aesthetic, ethical, ideological nature.

We suggest to look briefly at seven novels published in the last three decades to see the various roles assigned to photography by their authors: Out of this World (1988) by Graham Swift, Ulverton (1992) by Adam Thorpe, Master Georgie (1998) by Beryl Bainbridge, The Dark Room (2001) by Rachel Seiffert, The Photograph (2003) by Penelope Lively, Double Vision (2003) by Pat Barker and The Rain Before It Falls (2007) by Jonathan Coe.

The scenes of the novels are set widely apart and have time spans of various duration. Ulverton and Master Georgie have a mid-19th century setting, The Dark Room is centered round WWII, Out of this World and The Rain before It Falls contain their heroes’ long life stories, while The Photograph and Double Vision are set at the end of the last century and their characters are our contemporaries. The novels also differ by the particular place photographs occur in the novels, by the roles they play there, as well as by the issues associated with them.
Popularization and/or Trivialization of Philosophy in Voltaire's Narrative Candide or Optimism
Authors: Majksner Ivana , Oswald Tina Varga
Published: November 2016

Voltaire produced his works within the literary-historical period of Classicism and Enlightenment, in which the prevalent role of literature was educational. The period also dictated what genre, theme, style and structure authors should follow. However, more and more changes of literary genres appear, and the process of stratification of literature into high and trivial takes place. The aim of this paper is to describe the polarization of two mutually different processes involved in the literary shaping of Voltaire's philosophical narrative Candide or Optimism. In Voltaire's narrative, the popularization of philosophy, in order to simplify and illuminate the philosophical writings of G. W. Leibniz, results in the changes of style and content that become understandable to the general readership since they work within the scheme of an adventure novel. In this process, trivialization does not affect only the genre, but is also present in other parts of literary analysis and interpretation such as the theme, motifs, structure, characterization, narrative techniques, stylistic features, and so on.

Taxonomic diversity of cockroach assemblages (Blattaria, Insecta) of the Aptian Crato Formation (Cretaceous, NE Brazil)
Authors: Lee Shih-Wei
Published: November 2016

A comprehensive revision of 981 specimens of fossil cockroaches from the Lower Cretaceous laminated limestones of the Crato Formation of Northeast Brazil shows that they belong to eleven taxa, includingPiniblattella limai,P. magnasp. n.,Perlucipecta santanensis.sp. n.,Raptoblatta waddingtonae;Ocelloblattula santanensissp. n.,Elisama brevis(=E. americana, syn.n.),E. hindwingniisp. n.,Ponopterix axelrodi(=P. maximasyn.n.),Umenopterix burkhardicomb. n., andCratovitisma oldreadi(Umenocoleidae = Cratovitismidae syn.n. = Ponopterixidae syn.n.). The family Ectobiidae is numerically most abundant in the assemblage of cockroaches of the Crato Formation (83 % of cockroaches), followed by Blattulidae (13 %) and Umenocoleidae (4 %). 79.2 % of specimens are complete and fully articulated. Members of the family Alienopteridae are probably also present. Representatives of a relatively common Mesozoic superfamily Caloblattinoidea are missing. With the exception of the endemic generaCratovitismaandRaptoblattaand the exclusively Gondwanan genusOcelloblattula, all other genera were cosmopolitan. Taxonomic richness of cockroaches of the Crato Formation is thus rather low, and consists of geologically long-ranging and geographically-widespread genera, genera restricted to Gondwana, and short-ranging endemic genera found in the Crato Formation only.
A tiny short-legged bird from the early Oligocene of Poland
Authors: Bochenski Zbigniew M. , Tomek Teresa , Swidnicka Ewa
Published: November 2016

We describe an articulated partial leg of an Oligocene bird. It is one of the smallest avian fossils ever recorded. Its slender and exceptionally short tarsometatarsus, hallux as long as the tarsometatarsus and stout moderately curved claws agree with stem-group Apodidae (swifts), stem-group Trochilidae (hummingbirds), and stem-group Upupidae/Phoeniculidae (hoopoes/woodhoopoes). Unfortunately, due to the poor preservation of the specimen its more precise affinities remain unresolved. The specimen differs in many details from all other tiny Palaeogene birds and therefore most probably it represents a new taxon but it is too fragmentary to describe it. It is just the twelfth avian fossil from the Oligocene marine deposits of the Outer Carpathians and Central Palaeogene Basin — a huge area that covers south-eastern Poland, north-eastern Czech Republic and northern Slovakia — and therefore it adds to our very limited knowledge on the avifauna of that region. The remains of land birds from Jamna Dolna and other sites of the region can be attributed to the general sea level fall at that time, which led to limitation of the connection with the open ocean and resulted in many shallow shoals, temporary islands and exposed dry land areas along the coast.
Hittite kapart-/kapirt - ‘small rodent’ and Proto-Semitic *ˁkbr-t- ‘mouse, jerboa’
Authors: Kroonen Guus
Published: November 2016

The Hittite doublet kapart-/kapirt-, designating a small rodent, is currently assumed to continue an Indo-European formation. Hittitologists almost unanimously analyze it as an ablauting t-stem coined from the preverb *ko(m)- ‘together’ and the Indo-European root *bʰer- ‘to carry’, i. e. *ko(m)-bʰēr-t- or *ko(m)- bʰr̥-t. Accordingly, the meaning ‘small rodent’ is explained as having developed from ‘collector’ or ‘hoarder’. It appears that there is a good alternative to this etymology, however, as the Semitic languages offer evidence for a feminine t-stem to the root *ˁkbr- meaning ‘mouse; jerboa’, viz. Akkadian akbartu-, Phoenician ˁkbrt and Syriac ˁuḳbartā. It seems more plausible that this is the source of Hitt. kapart-/kapirt-.
Induktive versus abduktive Rekonstruktion
Authors: Hajnal Ivo
Published: November 2016

The method of comparative reconstruction is considered as the best instrument to reveal the prehistory of individual languages or linguistic families. It is inductive (data-driven) and seems to be much more reliable as the concurring method of internal reconstruction. Still it has been overlooked that each comparative reconstruction - to be innovative - has to be based on an initial premise. Such a premise is always the result of an abductive conclusion as used in internal reconstruction. Thus each comparative reconstruction has a core consisting of internal reconstruction. For syntactical reconstruction the following premise seems to be suitable: Linguistic structures and their changes obey the principles of universal grammar (e. g. the Minimalistic Program) and of grammaticalization. This premise proves fruitful for the explanation of the Early Greek augment */e-/< *h1e-. The augment can be determined as an original particle in the CP layer of the sentence. Later on it is reanalysed as a temporal particle, becomes part of the vP and underlies univerbation with the verb.
A Novel Current–Mode High–Frequency Polyphase Filter using Multi–Output Current Differencing Transconductance Amplifiers
Authors: Peng Hao , Wang Chunhua , Tian Xiaotong
Published: November 2016

This paper introduces a novel polyphase filter working at high centre frequency using multi-output current differencing transconductance amplifiers (MOCDTAs). The MOCDTA possesses characteristics of low input impedance, high output impedance, wide work frequency and linearly adjustable transconductance. The proposed filter consists of two MOCDTAs, two grounded capacitors, and no resistors. The features of low input impedance and high output impedance make it suitable for cascade. The bandwidth and centre frequency could be adjusted independently by external bias voltage VC
and VCa
. The image rejection ratio (IRR) could reach 31.6 dB at the centre frequency of 114 MHz, and its bandwidth could be 11.1 MHz. Besides, the centre frequency could be tuned from 38 MHz to 150 MHz with bandwidth of 20.1 MHz. Simulation results which verify the theory are included.
A Multi–Objective Optimization for Performance Improvement of the Z–Source Active Power Filter
Authors: Hosseini Seyed Mohsen , Beromi Yousef Alinejad
Published: November 2016

The high power dissipation is one of the most important problems of the z-source inverter (ZSI). By using an appropriate optimization scheme, the losses can be significantly reduced without any negative impact on the other characteristics of the inverter. In this paper, a multi-objective optimization is implemented in order to reduce the ZSI total losses as well as to improve the z-source active power filter (APF) performance. The optimization is focused on the four important objectives including power losses of the Z-source APF, the initial cost of the system components, the voltage and current ripples, and the boost factor of the z-source network. For these purposes, the multi-objective genetic algorithm (MOGA) is employed. The numerical and simulation results are presented to evaluate the optimization performance. The results show that a good balance can be achieved between the switching power losses, the voltage-current ripple levels, the component costs and the boost factor using the optimized parameters.

Objecive:

To evaluate the perinatal outcome of monochorionic-diamniotic twins conceived by assisted reproduction technology (ART).

Methods:

We compared data from a national population-based perinatal registry on perinatal outcomes of monochorionic-diamniotic twins conceived by ART with their dichorionic counterparts and with spontaneous monochorionic-diamniotic twins. We compared maternal characteristics, pregnancy complications and perinatal outcomes.

Results:

Monochorionic-diamniotic twin pregnancies (n=45) comprised 5.5% of all ART twins, and 9.3% of all monochorionic twins in this dataset. ART does not appear to increase the already high risk of monochorionicity compared to spontaneous conception, with the latter having an increased incidence for birth weight <1500 g [odds ratio (OD) 2.6, 95% confidence interval (CI) 1.2–5.4].

Conclusion:

Our results disagree with hospital-based data and suggest that monochorionic-diamniotic twins following ART are not at increased risk of adverse perinatal outcomes compared to spontaneous monochorionic-diamniotic twins as well as to dichorionc twins conceived by ART.

Investigating language change using Anglo-Norman spoken and written register data
Authors: Ingham Richard
Published: November 2016

Language change is generally considered to originate in the spoken mode before spreading to the written mode, although the latter provides all our available data for language change until recent times. While written mode representations of speech, such as fictional dialogue, can be used, their authenticity is hard to verify. This study addresses these issues by comparing the language of the Year Books, texts which attest to oral pleading in medieval courts, and include very extensive dialogue, with legal register written-mode origin texts, in the Parliament Rolls of Medieval England. Both sets of texts were written in Anglo-Norman, arose within a fairly homogenous speech community, and cover the same time period – late thirteenth century until c. 1350. It is shown that changes known to have occurred in later medieval French are instantiated at this time in the dialogic texts, but to a lesser degree or not at all in the written register texts. Features of morphology, lexical semantic extension, and discourse syntax in these sources indicate in each case that the innovation arose and spread first in the spoken origin source. Support from diachronic change is thus offered for a continuity assumption for the primacy of the spoken mode in present and past states of language.

Silicic acid polycondensation leads to the formation of amorphous silica. This process is of great importance to the survival of certain living organisms, such as diatoms and sponges, but presents a significant problem in various production facilities that use water for heating or cooling. In the latter, amorphous silica can be a recalcitrant deposit that can hamper proper system operation. Hence, inhibition of silicic acid polycondensation by chemical inhibitors is an intensely sought strategy by water system operators. In this manuscript, we report the inhibitory effect of zwitterionic phosphonated analogs (PPEI’s) of the cationic polymeric chemical additive polyethyleneimine (PEI) in mildly supersaturated silica solutions (500 ppm/8.3 mM “Si”) at pH=7. The inhibition efficiency of PPEI’s depends on a variety of parameters, such as concentration and degree of phosphonomethylation of the parent PEI polymer.

Published: November 2016

This work presents the studies on the epoxidation of allyl-glycidyl ether (AGE) over the Ti-SBA-15 catalyst. In these studies an aqueous hydrogen peroxide was used as an oxidizing agent and as a solvent methanol was applied. The studies on the influence the following parameters: temperature (20–80°C), molar ratio of AGE/H2O2 (1:1.5–5:1), methanol concentration (10–90 wt%), catalyst content (1–9 wt%) and reaction time (15–240 min.) were carried out and the most favourable values of these parameters were chosen (temperature 80°C, molar ratio of AGE/H2O2 = 5:1, methanol concentration 30 wt%, catalyst content 3 wt% and the reaction time 240 min.). At these conditions the functions describing the process reached the following values: the selectivity of diglycidyl ether (DGE) 9.2 mol%, the conversion of AGE 13.9 mol% and the efficiency of H2O2 conversion 89.9 mol%.
Bio-polishing sludge adsorbents for dye removal
Authors: Zaini Muhammad Abbas Ahmad , Alias Norulaina , Yunus Mohd. Azizi Che
Published: November 2016

The objective of this work is to evaluate the removal of methylene blue dye by bio-polishing sludge-based adsorbents. The adsorbents were characterized according to the specific surface area, pH upon the treatment and surface functional groups. The adsorption of dye was carried out at room temperature, and the adsorption data were analyzed using the isotherm and kinetics models. The bio-polishing sludge is rich in ash content, and the presence of surface functional groups varied with the treatment strategies. The specific surface area of adsorbents is between 7.25 and 20.8 m2/g. Results show that the maximum removal of methylene blue by sludge adsorbents was observed to have the following order: untreated sludge (SR) > zinc chloride-treated (SZ) > microwave-dried (SW) = potassium carbonate-treated (SK) > acid-washed (SH). The maximum adsorption capacities for SR and SZ as predicted by the Langmuir model are 170 and 135 mg/g, respectively. Although SR demonstrates a higher maximum removal than SZ, the latter exhibits greater removal intensity and rate constant even at high dye concentration. The bio-polishing sludge is a promising adsorbent for dye wastewater treatment.

Published: November 2016

The present study aims at the removal of Eu(III) from aqueous solutions by sorptive flotation process. This process involves adsorption of Eu(III) onto bentonite and kaolinite clays followed by floatation using sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB) collectors. The effect of adsorption parameters (pH, contact time, clay weight, Eu(III) concentration, ionic strength) as well as flotation parameters (collector and frother concentrations, bubbling time, concentrations of foreign cations and anions) on the removal efficiency of Eu(III) were studied. The obtained results show that Eu(III) ions are removed efficiently (R% ~ 95%) at pH=4 after 1 h shaking with clay and 15 min floatation. The adsorption kinetics of Eu(III) onto the employed clays followed the pseudo-second-order model and the equilibrium data fitted well to the Freundlich isotherm model.

Published: November 2016

This paper purposes to provide an user-friendly intelligent tool, integrating fuzzy controllers and multi-agent techniques, able to motivate and to support behavioral change of energy end-users, having as main objective to re-define the role of energy consumer in “prosumer” in the context of a reorganized decentralized energy market, now reported to intelligent grids (smart grids). Integration of interactive technologies in a decision support system for microgrids energy management optimizes: functioning from an economical point of view, active control of distributed generation, controlled consumption, loading the storage equipment. The added value of the proposed tool consists of integrating decision theory and artificial intelligence concepts in monitoring and control actions, allowing “prosumers”: to make energy usage data accessible and to demonstrate that energy savings can be achieved without compromising comfort levels.

The design of platinum based drugs is not a new field of interest. Platinum complexes are widely used as anticancer agents and currently, approximately 30 platinum(II) and platinum(IV) entered into some of the phases of clinical trials. A special place in today’s research belongs to platinum complexes with diammine ligands. A large number of edda (ethylenediamine- N, N’-diacetate)-type ligands and their corresponding metal complexes has been successfully synthesized. This article summarizes recent progress in research on edda-type-platinum complexes. Some of these agents achieves better effect compared to the gold standard (cisplatin). It has been shown that there is a possible relationship between the length of the ligand ester group carbon chain and its cytotoxic effect. In most cases the longer the ester chain is the greater is the antitumor activity. Of particular interest are the noticeable effects of some new platinum compound with edda-type ligand on cell lines that are known to have a high level of cisplatin-resistance. Exanimate complexes appear to have a different mode of mechanism of action compared with cisplatin which includes apoptotic and necrotic cell death. There are indications that further investigations of these compounds may be very useful in overcoming the problems associated global cancer statistic.
