Functional Cognitive Psychodiagnosis: An Exploratory Examination of a Complementary Tool

Authors: Vitali Tevelev, Yuval Wolf

ABSTRACT
A major goal of evidence-based psychotherapy is to assess specific cognitive or emotional schemata and behavioral patterns associated with a particular disorder. The present study is an exploratory attempt to form a quantitative basis for this sort of clinical work in terms of Anderson’s Information Integration Theory and the theory’s methodological counterpart-Functional Measurement. The participants of the study’ s three experiments were 24 adolescents who suffer from disruptive behavior disorders, 17 patients who suffer from a dual diagnosis (a combination of substance dependence and psychopathology), and 14 patients diagnosed as suffering from emotional disorders such as anxiety, depression, and panic attacks. The following three types of functional cognitive schemata were diagnosed: bio-psycho-social in the participants with disruptive behavior disorders; addiction in the participants with dual diagnosis, and inner speech schemata in the participants with emotional disorders. The results are presented in terms of the relative importance assigned to the components of each sort of schema. It is concluded that the study’s findings exemplify the viability of the information integration as an infrastructure of a complementary psychodiagnostic tool.

Evaluation of Standards and Interfering Compounds in the Determination of Phenolics by Folin-Ciocalteu Assay Method for Effective Bioprocessing of Biomass

Authors: Krishna Prasad Bastola, Yadhu Nath Guragain, Vamsi Bhadriraju,
Praveen Venkata Vadlani

ABSTRACT
Folin Ciocalteu (F-C) assay is the most widely used and convenient method to determine the total phenolics content in foods, herbs, and other plant extracts. Different phenolics standards such as gallic acid, ferulic acid, chlorogenic acid, catechol, and vanillic acid have been used for calibration curves in this assay method. Comparison of these standards, in single or combination of two or more, for more accurate determination of phenolics has not been reported so far. This study tested five single phenolics and seven combinations of mixed phenolic standards to evaluate the optimal standards for F-C method. The different standards were tested to calculate the phenolic content in three known test solutions. We also evaluated interference effect of various compounds in phenolics estimation by F-C method that is usually present in the lignocellulosic biomass-derived sugar solution, and in food products along with phenolics. Finally, the optimal standards with five phenolics were used for the determination of phenolics in alkali pretreated biomass extract. The results indicated that gallic acid was the best standard among the single phenolic compounds and five phenolic compounds solution was the best standard among the mixed phenolic solutions. The presence of glucose, HMF, furfural, and vitamin-B12 did not interfere in phenolic determination; whereas ascorbic acid, tyrosine, formic acid, and acetic acid strongly interfered the results. The results also showed that biomass pelleting process did not affect the generation of phenolics in alkali pretreatment extract.

Butterflies Extracts Show Antibacterial Activity

Authors: Reuven Rasooly, Miriam Rothschild, Yael Gov, Paul Wolferstan, Robert Nash, Paula Do, Naomi Balaban

ABSTRACT
Extracts of several British butterfly species were tested and shown to possess powerful bactericidal activity against gram-positive bacteria (tested on Staphylococcus aureus and Bacillus anthracis). The active compounds in the grass-feeding species were identified as hydroxylated pyrrolizidine alkaloids (PAs) related to loline with nitrogen at C-1. Lolines are known insecticidal and insect-deterrent compounds that are produced in grasses infected by endophytic fungal symbionts. Lolines also increase resistance of endophyte-infected grasses to insect herbivores. The butterfly-isolated pyrrolizidine alkaloids appear to be novel and non-toxic to human cells such as HaCat human skin keratinocytes and Hep-2 human epithelial cells. The discovery of novel agents from butterflies could lead to the development of new antimicrobials.

Value at Risk (VaR) Historical Approach: Could It Be More Historical and Representative of the Real Financial Risk Environment?

Author: Evangelos Vasileiou

ABSTRACT
The purpose of this paper is to suggest a new approach that improves the conventional Historical Value-at-Risk (HVaR) estimations’ accuracy and can be easily applied by anyone. The main assumption for the newly suggested method is “the more representative to the financial conditions the data inputs are, the better the VaR estimations”. Volatility is assumed to be the criterion for the “representative to the financial conditions” definition. In practice, the newly suggested approach does not use the previous x days observations as data inputs in the estimation process (as the HVaR does), but the last x filtered volatility (fv) observations of a “representative to the current financial conditions dataset”. Depending on the volatility value, each observation is classified in several regimes, from which the VaR is estimated depending on the examined day’s volatility. This way the HVaR approach is more historical. Continue reading

A Major Change in the Stratigraphy of the Santorini Volcano in Greece

Authors: Walter L. Friedrich, Annette Højen Sørensen, J. Richard Wilson,
Michael Fytikas, Spyridon Pavlides, Samson Katsipis

ABSTRACT
Two prominent and similar pumice series were described on Thera in 1879—the Upper and Lower Pumice Series (UPS and LPS). Since then, geologists have treated the two series separately because they seemingly occurred at distinct levels and had different ages. Here we show that these two pumice series are identical; there is no LPS on Santorini. All stratigraphic conclusions based on the LPS from Santorini should therefore be discarded. The water-filled Santorini caldera with its steep inner slopes existed before the eruption. Volcano-tectonic effects in connection with caldera formation created concentric terraces that were mantled by the products of the Late Bronze Age (LBA) eruption. Subsequent erosion only left remnants of the mantle behind. Topographic effects followed by slumping during sedimentation caused confusion of the stratigraphy on the caldera wall. Our results are supported by geological, paleontological and archaeological evidence. Furthermore, the caldera with its minerals, pigments, harbours and hot springs was accessible for the Thereans. This reinterpretation opens new perspectives for archaeological research. The catastrophic LBA eruption (previously called the Minoan eruption) destroyed a flourishing culture on Santorini and impacted neighbouring cultures around 1613 BC.

Some Structural Properties of Dynamically Drawn iPP Fibers

Author: Afaf M. Ali

ABSTRACT
Changes in the different structural parameters of iPP fibers during the dynamically cold drawing process were characterized. Using the dynamic mechanical cold drawing device attached to Fizeau interference system all the optical and structural properties can be measured. With the aid of this device the effect of the strain rate on the different structure properties was measured. The molecular orientations, molecular polarizability, molar reflectivity and shrinkage stress were measured. Reorientation of the molecules led to a significant variations in the measured structure properties of the drawn iPP fibers during applying the external tension.

New Osteological Data on Malaria in Sardinia from Antiquity to the Modern Era

Authors: Eugenia Tognotti, Andrea Montella, Peter J. Brown, Pasquale Bandiera

ABSTRACT
Malaria has been an important disease throughout the history, particularly in the Mediterranean. The island of Sardinia (Italy) was characterized by severe endemic malaria from antiquity until its eradication in 1950. It provides an exceptional and unique site to examine the history of the disease and its effects on human biology and ecology. Endemic malaria can cause chronic hemolytic anemias that may result in osteological signatures. This paper examines these markers, Porotic Hyperostosis (PH) and Cribra Orbitalia (CO), which are identified from skeletons uncovered in archaeological excavations in Northern Sardinia. Previous hypotheses based on historical references and genetic data suggest that the disease was absent on the island in prehistory and was imported, probably by slaves, during the Carthaginian period (6th to 3rd century BC). This article reports on the paleontological analysis of 283 skeletons excavated from seven archeological sites dating from 4700 BP to 1582 AD. Osteological remains were examined for markers CO and PH as a proxy variable for malaria. The findings support previous hypotheses about history of malaria over time.

Achieving Mobile Cloud Computing through Heterogeneous Wireless Networks

Authors: Amani S. Alnezari, Nasser-Eddine Rikli

ABSTRACT
A Mobile Cloud Computing environment with remote computing and vertical handover capabilities will be considered. A fuzzy logic model will be suggested for both the offloading and handover functions using energy, delay and computation complexity as criteria. Based on the application requirements, some rules will be proposed and evaluated when deciding on the offloading then the selection of the network that keeps the traffic carried to the cloud at an acceptable level. All this ought to be achieved in real time while the application is still running. The proposed engine will be implemented and run on an Android mobile device connected to Google’s App Engine servers. Results will be presented and analyzed, and conclusions will be provided.

Authors: Mónica Rodríguez-Pesina, Jorge García-Domínguez, Felipe García-Hernández, Luisa Maria Flores-Vélez, Octavio Domínguez

ABSTRACT
The thermal decomposition of ammonium perchlorate (AP) with Al and Zn metallic particles was studied at different heating rates in dry air atmosphere and the combustion behavior of AP/Al/Zn propellant was evaluated. The exothermic reaction kinetics was studied by differential thermal analysis (DTA) in non-isothermal conditions and compare with the thermal decomposition of pure AP and AP/aluminum particles analyzed in the same experimental conditions. The Arrhenius parameters were estimated according to the Ozawa and Kissinger methods. The calculated activation energies for the low and high temperature exothermic reactions were 91 and 229 kJ/mol for pure AP, 90 and 112 kJ/mol for 80 wt% AP/20 wt% Al particles. When zinc was incorporated, activation energy of 56 kJ/mol was determined for the only exothermic peak observed for 90 wt% AP/10 wt% Zn and 44 kJ/mol for 78.4 wt% AP/19.6 wt% Al/2 wt% Zn propellant composition.

Bacteriological Quality and Risk Factors for Contamination of Raw Mixed Vegetable Salads Served in Collective Catering in Abidjan (Ivory Coast)

Authors: Evelyne Toe, Adjéhi Dadié, Etienne Dako, Guillaume Loukou

ABSTRACT
The aim of this study was to determine the bacteriological quality of raw mixed vegetable salads served in collective catering in Abidjan and to assess the factors likely to favor contamination. An investigation was conducted to determine the practical risk of contamination. A total of 306 samples were collected and analyzed for the detection and enumeration of Enterobacteriaceae, E. coli and Salmonella according to standard microbiology methods. The most important risk factors were lack of training (96.7%), decontamination (84.0%), cross-contamination of vegetables in contact with fresh chicken or fish (76.7%) and salads that were uncovered and unprotected, thus exposed to the air and at ambient temperature for sale (97.7%). Theprevalence was 100%, 77.8% and 2.6% respectively for Enterobacteriaceae, E. coli and Salmonella. The average load of Enterobacteriaceae and E. coli was 4.93 log10 (CFU/g) and 1.89 log10 (CFU/g), respectively. Unsatisfactory microbiological quality samples were 52.3%. The results showed a failure of the sanitary quality in more than half of the products. Raising awareness in all of the workers in the food chain for vegetable salads is thus necessary to protect the health of the consumers.
