Studies on Thermoplastic Elastomer Based on Linear Low-Density Polyethylene and Latex Product Waste Modified with Thiocarbanilide

ABSTRACT Latex waste like glove waste was effectively modified using a new reclaiming agent, thiocarbanilide. This modified waste was blended with linear low-density polyethylene (LLDPE) to develop a novel thermoplastic elastomer. Both uncrosslinked and dynamically crosslinked blends were prepared and their properties were studied. The results were found to be comparable to those of conventional thermoplastic elastomers.
MODELING OF BATCH SYSTEM APPLICATION ON BACTERIOPHAGES TRANSPORT IN HOMOGENEOUS COARSE AQUIFER INFLUENCED BY PERMEABILITY IN ELELE , RIVERS STATE OF NIGERIA

Modeling of batch system in Bacteriophage transport in homogenous coarse soil influenced by permeability has been developed. The models were necessary because the contaminants were found to generate high concentration in ground water aquifer. Public health was deteriorating in the study area and the source of pollution was ignored due to lack of information. To solve the problem, mathematical models were developed to monitor the transport of these contaminants in a homogeneous formation, application of batch systems were applied due to uniformity of the formations in the study area. This conceptual framework was in line with the stratification of the soil, including the degree of predominant homogeneous deposition at shallow aquifers. The model was confirmed suitable to solve the pollution transport in the study location. Copyright © IJSEE, all rights reserved.
When Less Is More in Cognitive Diagnosis : A Rapid Online Method for Diagnosing Learner Task-Specific Expertise

Rapid cognitive diagnosis allows measuring current levels of learner domain-specific knowledge in online learning environments. Such measures are required for individualizing instructional support in real time, as students progress through a learning session. This article describes 2 experiments designed to validate a rapid online diagnostic method that was inspired by experimental procedures applied in classical cognitive studies of chess expertise. With the described rapid verification method, learners are required to rapidly verify suggested steps at various stages of a problem solution procedure. In this study involving 33 university students, a high degree of correlation was found between rapid testing scores and results of in-depth cognitive diagnosis based on observations of problem-solving steps using video recordings and concurrent verbal reports in the domains of kinematics (vector addition motion problems) and mathematics (transforming graphs of linear and quadratic functions). The article discusses possible applications of the suggested method in adaptive learning environments.
Volcanic stratospheric sulfur injections and aerosol optical depth from 500 BCE to 1900 CE

Abstract. The injection of sulfur into the stratosphere by explosive volcanic eruptions is the cause of significant climate variability. Based on sulfate records from a suite of ice cores from Greenland and Antarctica, the eVolv2k database includes estimates of the magnitudes and approximate source latitudes of major volcanic stratospheric sulfur injection (VSSI) events from 500 BCE to 1900 CE, constituting an update of prior reconstructions and an extension of the record by 1000 years. The database incorporates improvements to the ice core records (in terms of synchronisation and dating) and refinements to the methods used to estimate VSSI from ice core records, and it includes first estimates of the random uncertainties in VSSI values. VSSI estimates for many of the largest eruptions, including Samalas (1257), Tambora (1815), and Laki (1783), are within 10 % of prior estimates. A number of strong events are included in eVolv2k which are largely underestimated or not included in earlier VSSI reconstructions, including events in 540, 574, 682, and 1108 CE. The long-term annual mean VSSI from major volcanic eruptions is estimated to be ∼ 0.5 Tg [S] yr−1, ∼ 50 % greater than a prior reconstruction due to the identification of more events and an increase in the magnitude of many intermediate events. A long-term latitudinally and monthly resolved stratospheric aerosol optical depth (SAOD) time series is reconstructed from the eVolv2k VSSI estimates, and the resulting global mean SAOD is found to be similar (within 33 %) to a prior reconstruction for most of the largest eruptions. The long-term (500 BCE–1900 CE) average global mean SAOD estimated from the eVolv2k VSSI estimates including a constant background injection of stratospheric sulfur is ∼ 0.014, 30 % greater than a prior reconstruction. These new long-term reconstructions of past VSSI and SAOD variability give context to recent volcanic forcing, suggesting that the 20th century was a period of somewhat weaker than average volcanic forcing, with current best estimates of 20th century mean VSSI and SAOD values being 25 and 14 % less, respectively, than the mean of the 500 BCE to 1900 CE period. The reconstructed VSSI and SAOD data are available at https://doi.org/10.1594/WDCC/eVolv2k_v2 .
Fetal haemoglobin and alpha 1 microglobulin as biochemical markers in predicting preeclampsia in late first trimester and early second trimester of pregnancy

Background: Preeclampsia is a multi system disorder with placenta as the organ of origin and maternal endothelium being the organ of target. According to recent studies, the cell free haemoglobin induces oxidative stress mediated damage to the blood placenta barrier with consequently elevated levels of HbF in maternal blood. Alpha 1 microglobulin is an endogenous protein with antioxidant property, present in elevated levels in maternal blood in response to oxidative stress. This fact forms the basis for our study. The objective of the present study was to establish association between high levels of fetal hemoglobin and alpha 1 microglobulin in plasma of pregnant women between 10 to 16 weeks of gestational age and subsequent development of preeclampsia.Methods: This was a prospective cohort study undertaken in the Department of Obstetrics and Gynaecology, ISO -KGH, between December 2016 to November 2017. A total of 100 pregnant women were included in the study after getting informed written consent. Both primigravida and multigravida, belonging to age group of 20 to 35 years (singleton/ multiple) between 10 to 16 weeks GA and with BMI between 16 to 35 kg/m2 were included in the study. A woman with Diabetes mellitus, Hypertension, Renal disease, Epilepsy and Vascular disorders were excluded from the study.Results: The cut off value for alpha 1 microglobulin was 1.86ng/ml and the cut off value of fetal haemoglobin was 1.92ng/ml above which the pregnant women develop preeclampsia.Conclusions: Higher values of fetal hemoglobin and alpha 1 microglobulin in pregnant women between 10 to 16 weeks gestational age positively correlates with development of preeclampsia in those women.
The role of relative prices in a generalized new keynesian Phillips curve

Literatura reciente atribuye una fraccion importante de la volatilidad de la inflacion a los choques de costos. Este articulo desarrolla y estima un modelo microfundado, dinamico, estocastico y de equilibrio general, el cual establece un papel de primer orden para la dinamica de precios relativos. Una medida de desalineamientos de precios relativos aparece en la nueva curva Keynesiana de Phillips, del modelo, la cual resembla un choque de costos. El analisis de impulso respuesta sugiere que una interpretacion alternativa a los efectos de los choques de costos exogenos en la curva de Phillips se basa en la respuesta endogena de los precios relativos a choques exogenos que los perturban.
Evaluating Haste.App: Haskell in a web setting. Effects of using a seamless, linear, client-centric programming model

In this paper, we evaluate Haste.App, a newly developed Haskell library for distributed web applications. Haste.App promises to deliver multiple ease of use factors in addition to allowing the static type checking of Haskell to be extended over the network. It also pairs with the Haste compiler which compiles Haskell code to JavaScript. We conclude that Haste.App is a promising library that allows real world distributed web applications to be written in Haskell with ease. The seamless, client-centric programming model also has positive effects on programmer productivity. There are, however, some issues that will need to be addressed with Haste.App: some way of making sure the JavaScript is updated when the server is, standardisation when it comes to project structure, and some convenient way of handling DOM. In order to reach this conclusion, we evaluate Haste.App primarily based on three key aspects: performance, stability, and programmer productivity. The evaluation is performed by creating a simple online multiplayer board game and an attached lobby system.
Classifying Anomalous Mobile Applications Based on Data Flows

Mobile security becomes more important as users increasingly rely on the portable network devices. The security consultant firms indicate that the amount of mobile malware increases every year at a fast speed. Therefore, fast detecting mobile malware becomes an important issue. By applying reverse engineering techniques, a source code extraction module produces data flow information from the mobile application executable. The proposed static analysis-based detection system analyzes the data flow of the target software and it identifies if a data flow might leak sensitive data. The experimental results show that the proposed detection system can identify mobile malware efficiently. Keywordsmobile security, malware detection, static analysis.
DEMAND SYSTEM CHOICE BASED ON TESTING THE ENGEL CURVE SPECIFICATION

It is common to use a demand systems approach in estimating the key parameters from household consumption data. In conducting these studies the researcher is faced with selecting a functional form. In turn, each functional form implies a particular shape for the Engel curves. This analysis highlights the importance of testing the shape of Engel curves, especially if the researcher is interested in elasticity estimates well away from the sample mean. Using consumption data for selected households in Italy it is shown that many popular functional forms are rejected by the data.
CROSS-VALIDATED LOCAL LINEAR NONPARAMETRIC REGRESSION

Local linear kernel methods have been shown to dominate local constant methods for the nonparametric estimation of regression functions. In this paper we study the theoretical properties of cross-validated smoothing parameter selec- tion for the local linear kernel estimator. We derive the rate of convergence of the cross-validated smoothing parameters to their optimal benchmark values, and we establish the asymptotic normality of the resulting nonparametric estimator. We then generalize our result to the mixed categorical and continuous regressor case which is frequently encountered in applied settings. Monte Carlo simulation results are reported to examine the finite sample performance of the local-linear based cross-validation smoothing parameter selector. We relate the theoretical and simulation results to a corrected AIC method (termed AICc )p roposed by Hur- vich, Simonoff and Tsai (1998) and find that AICc has impressive finite-sample properties.
A LOOK AT A NEW CLASSIC1

A number of recent studies have focused on the question of the availability of Universal Grammar (UG) to the adult second-language (L2) learner. Some of these studies have considered developmental phenomena, and their authors have often come to opposite conclusions with regard to the acquisition of grammatical competence. For instance, Clahsen and Muysken (1986) argue that learners utilize only general processing strategies in their acquisition of an L2 while duPlessis, Solin, Travis & White (1987) insist that UG constrains L2 as well as L1learning. Other studies have utilized grammaticality judgments by adult speakers of an L2 as a basis for analysis. Felix (1988) and Bley-Vroman, Felix & Ioup (1988) suggest-in one way or another-that UG may indeed constrain L2 grammars. In contrast, Jacquelyn Schachter's ''Testing a Proposed Universal" (in press) appears to suggest the opposite, namely, that UG is no longer accessible to the adult, non-native speaker. What will be argued in this paper, however, is that Schachter's results, seen from the perspective of somewhat more recent linguistic theory, may be amenable to an interpretation that is consistent with adult access to UG. The discussion will begin with a short review of Schachter's study, which focuses especially on a principle of UG known as subjacency. The results of Schachter's study do not indicate that subjacency is available to adult nonnative speakers: Her subjects judged as grammatical a good number of sentences that appear to violate the principle of subjacency. What is of more interest is that Schachter's native-speaking controls also appear not to have access to subjacency on some test sentences, for they also judged as grammatical certain sentences that violate subjacency. The remainder of the paper is concerned with explaining the judgments of Schachter's native-
An Adaptable E-Learning Architecture Based on Learners' Profiling

These days modifications and supplements to e-learning are not enough to make them successful since flexibility and adaptability is missing. Different e- Learning architecture provide different kinds of learning experience to the learners. The lack of adaptive system is due to ―One size fits for all‖ concept. Currently the research is towards to learner oriented platforms putting student motivation, habits, expectations and learning styles (additional Koper, R.; Burgos, D (2005)). The concept of adaptation has become a prominent issue in e- learning. Systems allow the users to change some system parameters and adapt their behavior accordingly is known as adaption process. Systems that adapt based on the systems assumption are called as adaptive systems (additional santally mohammed issack). Since the system adapts to a person and personalizes the learning process it can be also known as personalized system (additional Paramythis, A.; Loidl-Reisinger). So to serve the learning community better there was a necessity to profile them and identify their requirements and provide an adaptive e- learning architecture which suits the individuals needs better. So the main objective of this research was to provide an adaptive e-learning system architecture which satisfies Felder Silverman learning style. Felder- Silverman's learning model (FSLM) was chosen since FSLM synthesis of these theories can be designed to easily translate them into strategies into a university setup.

Optical characterization of tissue-simulating phantoms with microparticles by Digital Image Plane Holography

Digital Image Plane Holography (DIPH) is a non-invasive optical technique which is able to recover the whole object wave. An object is illuminated and the diffused backscattered light is carried to a digital sensor by using a lens, where it interferes with a divergent reference wave with its origin in the lens aperture plane. Selecting each aperture image in the Fourier plane, the amplitude and the phase of the object beam are obtained. If two holograms are recorded at different times, after a small displacement, the reconstructed intensity distributions can be taken as a speckle field, while the phase difference distribution can be analyzed by an interferometric approach. In this work scattering media are investigated by using digital holography. The aim of this paper is to determine the viability of the technique to characterized optical properties of the sample. Different scattering media are modeled with different scattering properties. Each model generates a speckle pattern with different statistical properties (size, contrast, intensity). Both the visibility of the interferometric fringes and the properties of speckle pattern are related with optical properties of the media such as absorption and scattering coefficient. The ability to measure these properties makes the technique a promising method for biomedical applications.
The Securitization of Surplus Notes By Property and Casualty Insurers: Empirical Evidence

Surplus notes have been utilized by insurers for decades, although large insurers dominated in this market long ago. Lately popular securitization deals revive surplus notes as an efficient financing device for small and mid-sized insurers to tap capital markets at a reasonable cost. This paper intends to fill in the gap never touched by the prior studies by investigating what factors determine the insurers' decisions to securitize their surplus notes and what are the underlying rationales of surplus notes securitization. After implementing several models on censoring data, our results show that insurers' size, organization form and risk-based capital position significantly affect the participation decision made by insurers to securitize surplus notes, while the size and organization form impact the volume decision in a different way from they do the participation decision. Overall, our results suggest that deductions of financial distress costs and agency costs are important incentives for insurers to securitize their assets/liabilities.
EFFECT OF THIRTY SECOND STATIC STRETCH ON HAMSTRING MUSCLE FLEXIBILITY IN SUBJECTS OVER AGE SIXTY-FIVE

The purpose of this study w as to determ ine the effect of a thirty second static stretch on hamstring muscle length in a sam ple of healthy people over age sixty-five. Twelve individuals between the ag es of 65 and 89 w ere randomly assigned to two groups: a treatm ent group which performed one repetition of a thirty second static stretch of the hamstrings, one time per day for four weeks, and a control group which did not perform a hamstring stretch. ANCOVA results were calculated a s p=. 046, implying a significant treatm ent effect. Overall power w as calculated a s . 541. The results suggest that in the healthy elderly, thirty seconds is an adequate duration to apply a static stretch and achieve therapeutic effects.
Planning for whole-farm systems research at a credible scale: subdividing land into farmlets with equivalent initial conditions

Most research comparing different farming systems has been conducted on relatively uniform plots at small scales made necessary by the desire for sufficient replication of the systems and cost limitations. This paper describes an alternative approach to plan the allocation of land to three unreplicated whole-farm management systems such that each farmlet had equivalent starting conditions and yet was at a scale credible to both livestock producers and researchers. The paddocks of each farmlet were distributed across the landscape in a ‘patchwork quilt’ pattern after six iterations of a mapping exercise using a Geographic Information System. Allocation of paddocks took into account those variables of the landscape and natural resource capacity that were not able to be altered. An important benefit of the procedure was that it ensured that the farmlets were co-located with contiguous paddock boundaries so that all farmlets experienced the same climatic as well as biophysical conditions. An electromagnetic survey was conducted of the entire property and used in conjunction with a detailed soils map in order to classify areas into soil conductivity groupings. Equivalent areas of each soil type were allocated across the three farmlets. Similarly, land was distributed according to its topography so that no farmlet would be compromised by being allocated more low lying, flood-prone land than any other farmlet. The third factor used to allocate land to each farmlet was the prior fertiliser history of the original paddocks. This process ensured that each farmlet was objectively allocated equivalent areas of soil type, topography and fertiliser history thus avoiding initial bias among the farmlets. After the plan for all paddocks of each farmlet was finalised, new paddock boundaries were drawn and where necessary, fencing was removed, modified and added, along with re-arranged watering points. The farmlet treatments commenced in July 2000 when the first pasture establishment and differential fertiliser applications were carried out. Evidence from the electromagnetic survey and the Landsat imagery confirmed that the distribution of hydrologic soil conductivity and vegetation greenness were similar between all farmlets just before the commencement of the experiment.
ESTABLISHING STATUS OF NIGERIAN BUILDING DESIGN FIRMS BASED ON EUROPEAN CONSTRUCTION INSTITUTE TOTAL QUALITY MANAGEMENT MATRIX

Total Quality Management (TQM) is based on the philosophy of continuously improving goods and services. This research was aimed at establishing status of Nigerian Building Design Firms by studying the degree to which they were operating under the concept of TQM using European Construction Institute’s (ECI) matrix. Firms were grouped under types of design activities and questionnaire survey was used to generate data of the study. The study revealed that the overall average ECI Score of the groups of Nigerian Building Design Firms is 27.4. Thus, according to the ECI the Nigerian Building Design Firms belong to the class ‘The start of improvement’. Among the ECI quality factors, ‘Training, awareness, education and skill’ was recognised to be receiving the least attention from among the firms. It is recommended that the firms should particularly pay attention to this area in order to achieve the requirements and benefits of TQM.
Characterization of a Self-complementary Sierpinski Gasket Microstrip Antenna

Fractal antennae are recent topic of research interest. This work reports a self- complementary Sierpinski Gasket fractal microstrip patch antenna. The flrst iteration is named CSMASLI1, which stands for Complementary Sierpinski Microstrip Antenna Same Layer Iter- ation 1 and similarly the second iteration is named as CSMASLI2. The antennas are analyzed for two iterations using commercially available electromagnetic simulation software IE3D TM and CST Microwave Studio TM . The antenna radiates prominently at all resonant frequencies. The impedance bandwidth increases at higher harmonics. The radiation pattern is consistent for the difierent resonant frequencies and for difierent iterations. However some undulations are ob- served at higher resonance. Thus this new design can have usage in vehicle-mounted antenna for multiband wireless systems. A prototype was experimented which matches simulated results.
