Moral sensitivity in information security dilemmas

2019

Activities that undermine information security such as noncompliance with information security policies raise moral concerns since they can expose valuable information assets. Existing research shows that moral reflection could play an inhibitory role in one’s decision to undermine information security. However, it is not clear whether users interpret such decisions from a moral standpoint to engage in moral reflection in the first place. Users have to be morally sensitive before they engage in moral reflection. Moral sensitivity involves perceiving a situation as morally relevant, identifying the parties involved and perceiving possible courses of action. We examine moral sensitivity in se…

One pot light assisted green synthesis, storage and antimicrobial activity of dextran stabilized silver nanoparticles.

2014

Background Green synthesis of nanomaterials finds the edge over chemical methods due to its environmental compatibility. Herein, we report green synthesis of silver nanoparticles (Ag NPs) mediated with dextran. Dextran was used as a stabilizer and capping agent to synthesize Ag NPs using silver nitrate (AgNO3) under diffused sunlight conditions. Results UV–vis spectra of as synthesized Ag nanoparticles showed characteristic surface plasmon band in the range from ~405-452 nm. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) studies showed spherical Ag NPs in the size regime of ~50-70 nm. Face centered cubic lattice of Ag NPs was confirmed by powder X-ray diffraction (PXRD…

Differences and Similarities in Neuropathy in Type 1 and 2 Diabetes: A Systematic Review

2021

Background: Diabetic neuropathy is defined as the dysfunction of the peripheral nervous system in diabetic patients. It is considered a microvascular complication of diabetes mellitus. Its presence is associated with increased morbidity and mortality. Although several studies have found alterations at somatic motor, sensory levels and at the level of autonomic nervous system in diabetic patients, there is not a systematic approach regarding the differences in neuropathy between the major variants of diabetes, e.g., type 1 and 2 diabetes at both neurological and molecular level. Data sources: we systematically (Medline, Scopus, and Cochrane databases) evaluated the literature related to the …

Multi-parameter analysis of the obstacle scattering problem

2022

Abstract We consider the acoustic field scattered by a bounded impenetrable obstacle and we study its dependence upon a certain set of parameters. As usual, the problem is modeled by an exterior Dirichlet problem for the Helmholtz equation Δu + k 2 u = 0. We show that the solution u and its far field pattern u ∞ depend real analytically on the shape of the obstacle, the wave number k, and the Dirichlet datum. We also prove a similar result for the corresponding Dirichlet-to-Neumann map.

Pusaudžu izvairīgas/ierobežojošas pārtikas uzņemšanas traucējuma iezīmju, sensorā jutīguma un internalizētu uzvedības problēmu sakarības

2022

Darba mērķis ir izpētīt ARFID iezīmju, sensorā jutīguma un internalizēto uzvedības problēmu sakarības pusaudžiem. Pētījumā piedalījās 271 pusaudzis 14 – 18 gadu vecumā. Pētījumā tika izmantotas trīs aptaujas – Deviņu jautājumu ARFID aptauja, Īpaši jutīga bērna aptauja, Ahenbaha jaunieša uzvedības pašnovērtēšanas aptaujas internalizēto uzvedības problēmu skalas. Rezultāti parādīja, ka pastāv statistiski nozīmīgas pozitīvas saistības starp pusaudžu ARFID iezīmēm, sensoro jutīgumu un internalizētām uzvedības problēmām. Meitenēm tika novērotas izteiktākas ARFID iezīmes, sensorais jutīgums un internalizētas uzvedības problēmas nekā zēniem. Internalizētas uzvedības problēmu kopējie rādītāji progn…

N-Cinnamoyltetraketide Derivatives from the Leaves of Toussaintia orientalis

2015

Seven N-cinnamoyltetraketides (1−7), including the new Ztoussaintine E (2), toussaintine F (6), and toussaintine G (7), were isolated from the methanol extract of the leaves of Toussaintia orientalis using column chromatography and HPLC. The configurations of E-toussaintine E (1) and toussaintines A (3) and D (5) are revised based on single-crystal X-ray diffraction data from racemic crystals. Both the crude methanol extract and the isolated constituents exhibit antimycobacterial activities (MIC 83.3−107.7 μM) against the H37Rv strain of Mycobacterium tuberculosis. Compounds 1, 3, 4, and 5 are cytotoxic (ED50 15.3−105.7 μM) against the MDA-MB-231 triple negative aggressive breast cancer cel…

EXPERIMENTAL INVESTIGATION OF DILUTE SOLID-LIQUID SUSPENSION IN AN UNBAFFLED STIRRED VESSELS BY A NOVEL PULSED LASER BASED IMAGE ANALYSIS TECHNIQUE

2009

The availability of experimental information on solid distribution inside stirred tanks is a topic of great importance in several industrial applications. The measurement of solid particle distribution in turbulent multiphase flow is not simple and the development of suitable measurement techniques is still in progress. In this work a novel non-intrusive technique for measuring particle concentration fields in solid-liquid systems is employed. The technique makes use of a laser sheet, a high sensitivity digital camera for image acquisition and a Matlab procedure for post-processing the acquired images. Experimental data are here obtained for the case of an unbaffled stirred tank. Stable tor…

Loss Aversion and Risk Aversion in Non-Clinical Negative Symptoms and Hypomania

2020

In the field of behavioral decision-making, “loss aversion” is a behavioral phenomenon in which individuals show a higher sensitivity to potential losses than to gains. Conversely, “risk averse” individuals have an enhanced sensitivity/aversion to options with uncertain consequences. Here we examine whether hypomania or negative symptoms predict the degree of these choice biases. We chose to study these two symptom dimensions because they present a common theme across many syndromes with compromised decision-making. In our exploratory study, we employed a non-clinical sample to dissociate the hypomanic from negative symptom dimension regarding choice behavior. We randomly selected a sample …

The Influence of Chemical Composition of Commercial Lemon Essential Oils on the Growth of Candida Strains

2013

Candida yeasts are saprophytes naturally present in the environment and forming colonies on human mucous membranes and skin. They are opportunistic fungi that cause severe and even fatal infections in immunocompromised individuals. Several essential oils, including eucalyptus, pine, cinnamon and lemon, have been shown to be effective against Candida strains. This study addresses the chemical composition of some commercial lemon essential oils and their antifungal potential against selected Candida yeast strains. Antifungal potential and minimum inhibitory concentrations were determined for six commercial lemon essential oils against five Candida yeast strains (Candida albicans 31, Candida t…
