Characteristics of Sorbent Products Obtained by the Alkaline Activation of Waste from Waste Incineration Plants

Abstract In Poland, by 2020 430,000 Mg of hazardous waste will be formed annually by the combustion of waste. This waste must be properly managed so as not to endanger the environment. One promising way to manage selected waste is to process it in the synthesis of materials characterised by sorption properties. The results presented in this paper concern the possibility of producing sorbents from waste materials marked with codes 190112 and 190114, which came from two waste incineration plants in Poland. Alkaline activation was performed using two methods: a) hydrothermal, in a solution of 8 M NaOH at 75°C for 24 h; and b) in an autoclave, using a solution of 2 M NaOH at 140°C for 6 h. XRD analyses led to the identification of materials after synthesis of the following zeolite phases: analcime, chabazite and thomsonite. chabazite and analcime can be valuable absorbent materials.
ASSESSMENT OF IMPACT OF CLIMATE CHANGE ON POTATO AND POTENTIAL ADAPTATION GAINS IN THE INDO-GANGETIC PLAINS OF INDIA

India is the second largest producer of potato in the world. The Indo-Gangeticplains (IGP) is the main potato growing region accounting for almost 85% of the1.8 Mha under the crop in India where it is grown as an irrigated crop during thewinter season. Since IGP is in sub-tropical plains, duration of the thermally suitablewindow is the main determinant limiting yields. Hence the impact of climatechange on potato in the IGP was assessed using MIROC HI.3. 2 A1b and B1,PRECIS A1b, A2, B2 scenarios and estimated the potential adaptation gains. Thepotato crop duration in the IGP is projected to decrease due to climate change. Theevapotranspiration (ET) is projected to increase while the water use efficiency(WUE) for potato yield is projected to decline in future climates as a consequenceof low threshold temperatures for decline in WUE and yield than the ET. Resultsindicate that the upper threshold for ET decrease is ~23 oC while that for WUE is15 oC. The optimal temperatures for tuber yield is ~17 oC and thus the reduction inWUE in future climates is discernable. Climate change is projected to reducepotato yields by ~2.5, ~6 and ~11% in the IGP region in 2020 (2010-2039), 2050(2040-2069) and 2080 (2070-2099) time periods. Change in planting time is thesingle most important adaptation option which may lead to yield gains by ~6% in2020 and its combination with improved variety or additional nitrogen may be required to adapt to climate change leading to positive gains by ~8% in 2020 andby ~5% even in 2050. However, in 2080 adoption of all the three adaptationstrategies may be needed for positive gains. Intra-regional differences in the impactof climate change and adaptation gains are projected; positive impact in northwestern IGP, gains in Central IGP with adaptation and yield loss in eastern IGPeven with adaptation.
A Phenomenology of Tourist Experiences

Contemporary studies of tourism see the tourist experience as either something essentially spurious and superficial, an extension of an alienated world, or as a serious search for authenticity, an effort to escape from an alienated world. It is argued that neither of these views is universally valid. A more discriminating distinction between five types of tourist experiences is proposed, based on the place and significance of tourist experience in the total world-view of tourists, their relationship to a perceived `centre' and the location of that centre in relation to the society in which the tourist lives. It is proposed that the resulting continuum of types of tourist experience is both more comprehensive than alternative conceptual frameworks and capable of reconciling and integrating the conflicting interpretations arising from earlier studies.
Antiarrhythmic effects and ionic mechanisms of oxymatrine from Sophora flavescens

Accumulating evidence indicates that oxymatrine may exert protective effects on the cardiovascular system. This study was designed to evaluate the antiarrhythmic effects as well as the electrophysiological properties of oxymatrine. The antiarrhythmic activity of oxymatrine was observed in a rat model of arrhythmia induced by coronary ligation. Action potential duration (APD), L‐type calcium current (ICa‐L), transient outward potassium current (Ito) and inward rectifier potassium current (IK1) in rat ventricular myocytes were recorded by utilizing the whole cell patch‐clamp technique. The results showed that administration of oxymatrine significantly delayed the onset of ventricular arrhythmia, decreased the duration of ventricular arrhythmia and reduced the arrhythmia score of arrhythmic rats. The beneficial effects of oxymatrine may be related to the shortening of APD through reduction of ICa‐L, enhancement of Ito and inhibition of IK1. Copyright © 2010 John Wiley & Sons, Ltd.
Preordering for Chinese-Vietnamese Statistical Machine Translation

Word order is one of the most significant differences between the Chinese and Vietnamese. In the phrase-based statistical machine translation, the reordering model will learn reordering rules from bilingual corpora. If the bilingual corpora are large and good enough, the reordering rules are exact and coverable. However, Chinese-Vietnamese is a lowresource language pair, the extraction of reordering rules is limited. This leads to the quality of reordering in Chinese-Vietnamese machine translation is not high. In this paper, we have combined Chinese dependency relation and Chinese-Vietnamese word alignment results in order to pre-order Chinese word order to be suitable to Vietnamese one. The experimental results show that our methodology has improved the machine translation performance compared to the translation system using only the reordering models of phrase-based statistical machine translation. key words: Chinese-Vietnamese machine translation, preordering, word alignment, Chinese grammatical relations, dependency relations
Anti-Phishing Models: Main Challenges

Phishing is a form of online identity theft in which the attacker attempts to fraudulently retrieve a legitimate user's account information, logon credentials or identity information in general. The compromised information is then used for withdrawing money online, taking out cash advances, or making purchases of goods and services on the accounts. Various solutions have been proposed and developed in response to phishing. As phishing is a business problem, the solutions target both non-technical and technical areas. This paper investigates the current anti-phishing solutions and critically reviews their usage, security weaknesses and their effectiveness. The analysis of these models points to a conclusion that technology alone will not completely stop phishing. What is necessary is a multi-tiered, organised approach: user awareness, technical and non-technical solutions should work together.
Boundedness of pretangent spaces to general metric spaces

Let (X,d,p) be a metric space with a metric d and a marked point p. We define the set of w-strongly porous at 0 subsets of [0,\infty) and prove that the distance set {d(x,p): x\in X} is w-strongly porous at 0 if and only if every pretangent space to X at p is bounded.
Unstructured Grid Solutions for Incompressible Laminar Flow over a Circular Cylinder Using a Particular Finite Volume-Finite Element Method

A numerical modeling of a 2D Navier-Stokes equation by a particular vertex centered control volume framework on an unstructured grid is presented in this paper. Triangular elements are applied with an effective high performance fully coupled algorithm, to simulate incompressible laminar flow over a circular cylinder. The cell face velocities in the discretization of the continuity and momentum equations are calculated by a combined linear and momentum interpolation scheme, respectively, and their performances are compared. Flow analyses have been conducted based on various Reynolds numbers up to 200 for the steady and unsteady flows using structured and unstructured grids. The robustness and accuracy of the scheme in the unstructured mesh are proved using the benchmark problems of incompressible laminar flow over a circular cylinder at low and medium Reynolds numbers. Results have been compared with the structured grid results, both cases with equal cell numbers and same strategy for the mesh refinement. Current results display good agreement with the experimental values. Overall, it is shown that, using the suggested method for the current problem, unstructured grids are highly competitive with the structured grids.
Chemical composition and anti-diabetic properties of Jatropha curcas leaves extract on alloxan induced diabetic wistar rats

This study evaluates the chemical composition and anti-diabetic properties of fresh and shade dried Jatropha curcas aqueous leaves extracts (JCLE) on alloxan induced diabetic female wistar rats. Seven (7) kg of J. curcas leaves were pulverized and aqueous extracts produced. Thirty five (35) mature female rats were grouped into seven of five animals per group according to their body weights. Blood samples were collected for baseline data before inducing diabetes. Various groups of rats were fed graded doses (100, 200 and 300 mg of JCLE, respectively. Blood glucose was tested every seven days using glucometer. The animals were treated for 21 days with JCLE, blood samples were collected for liver enzyme function test, liver and pancreas tissues collected for histopathology. The results obtained were analysed statistically using analysis of variance (ANOVA) and Duncan Multiple range student test. Result shows that proximate composition of JCLE had higher protein, fat and carbohydrate concentrations in shade dried than the fresh samples. The vitamin, mineral and phytochemical compositions varied but higher in shade dried JCLE also than the fresh. Rats treated had significant (p<0.05) reduction in blood glucose level. Liver enzymes was higher with shade dried JCLE. The current study provides some useful insight into the anti-hyperglycemic potency of JCLE in alloxan induced diabetics and seems to repair some organs damages. Key words: Blood glucose, Jatropha curcus, liver enzymes, diabetic.
Empirical Research of VAR on HS 300 Stock Index and HS 300 Stock Future

Growing financial market creates unprecedented volatility for investors, so high attention of risk monitoring for assets is required intensively in recent years. There are several ways to monitor Value at risk for single assets or portfolio assets. This project will introduce and use standard historical simulation and trading-weighted historical simulation, variance –covariance to monitor HS 300 stock index and HS 300 stock index future. Additionally, it applies both of two methodologies to compare Value at risk of hedged and unhedged assets. In the end, it can be concluded that different methodology has its own disadvantage and advantage and it needs back testing to test the forecast of VAR model. This project uses trading weighted historical simulation and unconditional coverage to improve and test the forecast of value at risk estimated by historical simulation model.
Cancellation policies in combination with scarcity- and social proof appeals : a study into the effects of cancellation policies and persuasion cues on consumer responses within the online booking industry

This research focuses on the relationship between cancellation policies and persuasion heuristics on consumer responses (attitude towards the ad, attitude towards the product and purchase intention) in an online booking environment. Online Travel Agents (OTA's) often use persuasion signals and "free cancellation" banners simoultaniously in their advertisement, however, no research is found that probed the interaction between these constructs. This research builds on two assumptions that might explain the interaction effects. In addition to this, main effects are expected from cancellation, social proof and scacrity on the dependent variables. The following managerial implications are given: OTA’s need to explicitly incorporate social proof appeals in their advertisement designs, since this can result in positive attitudes towards their advertisements, towards their products and increases consumers’ purchase intentions. Further, when OTA’s strive for the most positive attitude towards the advertisement, they should include social proof appeals in their ads, and are advised not to combine them with free cancellations signals. However, if they want to use ads without social proof appeals, they should provide visitors with free cancellation signals. Moreover, marketers should be cautious with scarcity appeals, since it can have a negative influence on consumers’ attitudes and behavioural intentions. Finally, since banners with “free cancellation” do not significantly influence consumers attitudes and behavioural intentions, it is advised to OTA’s to not use free cancellation signals too often.
Strategy tools-in-use: A framework for understanding “technologies of rationality” in practice

: In response to critiques of strategy tools as unhelpful or potentially dangerous for organizations, we suggest casting a sociological eye on how tools are actually mobilized by strategy makers. In conceptualizing strategy tools as tools-in-use, we offer a framework for examining the ways that the affordances of strategy tools and the agency of strategy makers interact to shape how and when tools are selected and applied. Further, rather than evaluating the ‘correct’ or ‘incorrect’ use of tools, we highlight the variety of outcomes that result, not just for organizations but also for the tools and the individuals who use them. We illustrate this framework with a vignette and propose an agenda and methodological approaches for further scholarship on the use of strategy tools.
Medikamentöse Langzeittherapien zur Prognoseverbesserung bei Leberzirrhose und zur Vermeidung von Komplikationen der portalen Hypertension

Zusammenfassung Die portale Hypertension bei Patienten mit Leberzirrhose kann nicht nur durch interventionelle (TIPS: transjugulärer portosystemischer Stent-Shunt) oder operative Shuntanlagen, sondern auch medikamentös beeinflusst werden. Zahlreiche Studien beschäftigten sich mit der Frage, ob diese Substanzen bei dauerhafter Gabe zu einer Prognoseverbesserung bei Patienten mit Leberzirrhose führen können. Nicht selektive Betablocker (NSBB), Statine, Antibiotika, Enoxaparin und Albumin haben viele Angriffspunkte in der Pathogenese der portalen Hypertension oder bei Dekompensation der Leberzirrhose, sodass sie grundsätzlich als Kandidaten für eine Langzeittherapie infrage kommen. Während es für NSBB, Antibiotika und Albumin klare Indikationen in der Versorgung von Patienten mit dekompensierter Leberzirrhose gibt, ist dies weniger geklärt für den Einsatz von Statinen oder Antikoagulanzien. Neuere Untersuchungen ergaben widersprüchliche Ergebnisse, wenn der primäre Endpunkt einer Studie die Prognoseverbesserung oder die Vermeidung einer Dekompensation der Zirrhose durch eine dauerhafte medikamentöse Therapie war. Zum jetzigen Zeitpunkt ergibt sich aufgrund der aktuellen Studienlage keine Veranlassung, das bisherige, in Leitlinien abgesicherte Vorgehen im täglichen Alltag zu ändern. Diese Übersicht gibt einen Überblick zum Einsatz von NSBB, Antibiotika, Statinen, Antikoagulanzien und Albumin bei Komplikationen der portalen Hypertension insbesondere im Hinblick auf ihren dauerhaften Einsatz zur Verbesserung des Überlebens von Patienten mit Leberzirrhose.
Adesão ao Padrão Alimentar Mediterrânico de Crianças e Adolescentes com Diabetes Mellitus Tipo 1

Introduction: Diet is a cornerstone in the management of Type 1 Diabetes Mellitus (T1DM) in youth. The Mediterranean Dietary Pattern (MDP) is currently one of the healthiest dietary models. There is a gradual abandonment from this diet by the younger population. Objective: To evaluate and characterize adherence to MDP by children and adolescents with T1DM. To correlate the adoption of specific dietary habits associated with T1DM with the adherence to MDP and other variables studied. Methods: 65 children and adolescents with T1DM, attendants of APDP, participated in the study. Sociodemographic and metabolic data were collected, and a questionnaire (KIDMED Index) was applied, together with three questions related to specific dietary habits. Results: Participants had a mean age of 13 years, 6 years of diabetes evolution and 7.96% of hemoglobin A1c. The majority of the sample (90.8%) expressed a strong adherence to MDP, with the remaining showing moderate adherence (9.2%). Strong adherence was associated with ages below 12 years (p = 0.004), less years of diabetes (p = 0.067), and insulin therapy with SCII (p = 0.081). The propensity to simultaneously adopt the three specific dietary habits was rare. The association of these habits with the variables studied was similar to the results obtained in relation to the adherence to MDP. Conclusions: The strong adherence to the MDP by children and adolescents with T1DM reveals that they adopt health-promoting dietary habits, contributing to the control of T1DM. However, it is relevant to rethink strategies of nutritional intervention to adolescents.
Macular Thickness Asymmetry Measurements in Relatives of Primary Open Angle Glaucoma Patients

Background: A family history of glaucoma was found to carry a relative risk of 2.1 times for being associated with at least possible primary open angle glaucoma (POAG) in middle aged and older individuals. Around half of all POAG patients have a positive family history and their first degree relatives have an approximately 9-fold increased risk of developing glaucoma. Objective: the aim of the present study was to demonstrate possible early macular alterations in young relatives of POAG patients using spectral domain optical coherence tomography (SD-OCT) posterior pole asymmetry analysis (PPAA) map. Patients and methods: in a prospective comparative study; 40 subjects were classified into 2 groups: group of young healthy relatives of POAG patients and another group of young healthy subjects as control. All participants had OCT of the PPAA, retinal nerve fiber layer (RNFL), ganglion cell complex (GCC) and hemi-field macular thickness. Results: There was no statistically significant difference between the relative and control group in aspect of RNFL, macular hemi-fields and PPAA measurements (P-value >0.05). Regarding GCC thickness, there were statistically significant differences between both groups in the superior, inferior and nasal thickness measurements. Conclusion: Young healthy relatives of POAG patients didn’t show any early glaucomatous damage when compared with controls except for GCC thickness which showed statistically significant decrease.
The Predictive Validity of Measures of Teacher Candidate Programs and Performance

Calls for evidence-based reform of teacher preparation programs (TPPs) suggest the question: Do the current indicators of progress and performance used by TPPs predict effectiveness of their graduates when they become teachers? In this study, the indicators of progress and performance used by one program are examined for their ability to predict value-added scores of program graduates. The study finds that rating instruments, including disposition surveys, clinical practice observation ratings, and portfolio assessments, each measure a single underlying dimension rather than the multiple constructs they were designed to measure. Neither these instruments nor teacher candidates’ scores on standardized exams predict their later effectiveness in the classroom based on value-added models of student achievement. Candidates’ grade point averages during their preparation program and number of math courses were positively associated with their students’ math score gains. These findings suggest a need for better instruments to measure prospective teachers’ progress toward proficiency.
A Ploidy Increase Promotes Sensitivity of Glioma Stem Cells to Aurora Kinases Inhibition

Glioma stem cells account for glioblastoma relapse and resistance to conventional therapies, and protein kinases, involved in the regulation of the mitotic machinery (i.e., Aurora kinases), have recently emerged as attractive therapeutic targets. In this study, we investigated the effect of Aurora kinases inhibition in five glioma stem cell lines isolated from glioblastoma patients. As expected, cell lines responded to the loss of Aurora kinases with cytokinesis failure and mitotic exit without cell division. Surprisingly, this resulted in a proliferative arrest in only two of the five cell lines. These sensitive cell lines entered a senescent/autophagic state following aberrant mitotic exit, while the non-sensitive cell lines continued to proliferate. This senescence response did not correlate with TP53 mutation status but only occurred in the cell lines with the highest chromosome content. Repeated rounds of Aurora kinases inhibition caused a gradual increase in chromosome content in the resistant cell lines and eventually caused a similar senescence response and proliferative arrest. Our results suggest that a ploidy threshold is the main determinant of Aurora kinases sensitivity in TP53 mutant glioma stem cells. Thus, ploidy could be used as a biomarker for treating glioma patients with Aurora kinases inhibitors.
Close Approaches of Debris to LARES Satellite During Its First Four Years of Operation

Since its launch in February 2012, the LAser RElativity Satellite (LARES) of the Italian Space Agency experienced four close approaches with space debris. LARES orbits at an altitude of 1450 km, in a region where the density of space debris has a peak. However, the probability of an impact with a debris during the operational life of the satellite was reasonably low. The analysis of the close approaches identified three of the objects, that are from two peculiar population of objects. This paper discusses the problem of space debris in low orbit, the approaches occurred with LARES, and some possible scenarios related to space regulations and space law in case of an impact.
Anthropogenic and habitat correlates of hybridization between hatchery and wild brook trout

Human activities are breaking down barriers to interpopulation hybridization with results that range from populations that resist introgression to populations at serious risk of genetic extinction, particularly between wild and hatchery fish because of the routine stocking of lakes and streams containing wild populations. We investigated whether specific human actions and (or) habitat characteristics were associated with the extent of hybridization between hatchery and wild brook trout (Salvelinus fontinalis) occupying lakes in Algonquin Park, Ontario, Canada. Hatchery and wild trout tended to hybridize more in lakes (i) supporting smaller populations (i.e., having lower pH and situated at higher elevations), (ii) stocked earlier in the season, and (iii) with greater exposure to other human activities (fishing). Our results highlight how particular human activities may interact with specific habitat conditions to elicit hybridization in wild populations. Hence, the use of readily available habitat and lan.
