Security framework for dynamic service-oriented IT systems
2018
The paper proposes a framework for dynamic service-oriented IT systems security. We review the context of service-oriented architecture (SOA), which constitutes a paradigm of dynamic system configuration including security constraints at the system module development stage, supporting with the domain-driven resources, carrying out routine SOA maintenance and implementing XML-compatible parsing technologies in order to improve the system performance. Likewise, we discuss the fundamental differences between security management systems with traditional centralized and monolithic architecture and service-oriented IT systems from the perspective of security-related issues. Web services security …
Legacy Effects of Contrasting Long-Term Integrated Weed Management Systems
2022
To reduce reliance on herbicides and maintain crop productivity, integrated weed management (IWM) seeks to optimize synergies between diverse sets of weed management practices combined at the cropping system scale. Nevertheless, data on weed community response to the long-term implementation of IWM practices remain scare. Here, we assessed the effects of four IWM systems with contrasting objectives and practices (S2: transition from superficial tillage to conservation agriculture; S3: no-mechanical weeding; S4: mixed mechanical and chemical weeding; S5: herbicide-free; all with 6 year rotations) compared to a conventional reference (S1: herbicide-based with systematic plowing and a 3 year r…
La seguridad vial laboral: la influencia de los accidentes de tráfico en el entorno laboral
2019
Los desplazamientos relacionados con el trabajo son algo fundamental (e indispensable) para las personas, la industria y la economía del mundo actual. Sin embargo, ello da lugar a altas tasas de siniestralidad vial de los trabajadores, hecho que se ha convertido una preocupación manifiesta para la salud ocupacional y, tratándose de un asunto que involucra la seguridad vial general, también para la salud pública. En este sentido, distintos estudios coinciden en resaltar la necesidad de realizar investigaciones al respecto y establecer líneas de acción de carácter institucional basadas en la evidencia, enmarcadas en la actuación permanente y los estudios epidemiológicos, como primera estrateg…
Kritisku gadījumu analīze 11. klases skolēnu pašrefleksijas prasmju attīstībā angļu valodas stundās
2016
Darba mērķis ir izpētīt, kā kritisku gadījumu analīze ir izmantojuma 11. klases angļu valodas (kā svešvalodas) stundās, lai veicinātu skolēnu pašrefleksijas prasmes. Pētījumā piedalījās divdesmit divi 11. Klases skolēni un viens skolotājs. Pētījums noformēts kā skolotāja portfolio. Darba praktiskā daļa pamatota ar teorētiskiem pētījumiem. Pētījumā nepieciešamie dati iegūti, veicot skolēnu aptaujas, individuālās un grupu intervijas, skolēnu pašrefleksijas žurnālu un analizējot skolēnu rakstiska atsauksmes. Lai attīstītu skolēnu pašrefleksijas prasmes un nosacījuma palīgteikumu (conditional phrases) lietojumu, pētījumā tika izmantota Flanagana (Flannagan, 1954) un Tripa (Tripp, 1993) attīstīt…
Itsemurhatartunnan taikauskosta: The Moth Diaries (2011) ja 13 Reasons Why (2017)
2018
Artikkeli käsittelee kahden itsemurhaa kuvaavan populaarikulttuurin tapausesimerkin, The Moth Diaries -elokuvan ja 13 Reasons Why -sarjan, ja tabun käsitteen välityksellä itsemurhaan liitettyä tartunnan pelkoa ja tämän pelon ilmenemistä viihteen ja median representaatioita säätelevässä Werther-efektissä. Keväällä 2017 julkaistun kohutun 13 Reasons Why -Netflix-sarjan ensimmäisen kauden vastaanotto ilmentää sosiologien, psykologien ja kansanterveystieteilijöiden tunnetuksi tekemää Werther-efektiä, median välittämäksi pelättyä itsemurhatartuntaa. Kanadalainen kauhudraama The Moth Diaries (2011) taas käsittelee sisällössään vanhemmalta lapselle periytyvää itsemurhatartuntaa vampyyrin hahmon vä…
El acceso al empleo público en el Perú y España [Análisis del Derecho Comparado en la regulación del empleo público].
2015
En las líneas secuenciales que ilustran esta investigación, encontrará un análisis del Derecho Comparado sobre el sistema de acceso al empleo público en Perú y España, incluidos los principios que los rigen, sus modos de acceso, tipos y procesos de evaluación y de selección, las estructuras de selección y otros muchos aspectos que integran el sistema de acceso al empleo público en la regulación de cada país. En ese sentido, en la primera parte de nuestra investigación encontramos un régimen de servicio civil estructural y organizativo diferente, que nos introdujo en la necesidad de establecer nociones básicas para permitir al lector entrar en el contexto de cada esquema de servicio público.…
Comparison of essential oil components and in vitro anticancer activity in wild and cultivated Salvia verbenaca.
2015
The objectives of our research were to study the chemical composition and the in vitro anticancer effect of the essential oil of Salvia verbenaca growing in natural sites in comparison with those of cultivated (Sc) plants. The oil from wild (Sw) S. verbenaca presented hexadecanoic acid (23.1%) as the main constituent, while the oil from Sc plants contained high quantities of hexahydrofarnesyl acetone (9.7%), scarce in the natural oil (0.7%). The growth-inhibitory and proapoptotic effects of the essential oils from Sw and Sc S. verbenaca were evaluated in the human melanoma cell line M14, testing cell vitality, cell membrane integrity, genomic DNA fragmentation and caspase-3 activity. Both t…
COVID-19 in Severe Asthma Network in Italy (SANI) patients: Clinical features, impact of comorbidities and treatments
2020
To the Editor Since the end of February 2020 Italy, first non- Asian Country, has reported an ever increasing number of COronaVIrus Disease 19 (COVID-19) patients, which has reached over 200,000 confirmed Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) infected subjects and resulted in more than 34000 deaths (data updated to June 19th, 20201).Patients with asthma are potentially more severely affected by by SARS-CoV-2 infection 2 and it is well established that respiratory viral infections are associated with severe adverse outcomes in patients with asthma, including increased risk of asthma exacerbation episodes 3. Nonetheless, according to the epidemiological studies publishe…
Inhibition of denitrification and N2O emission by urine-derived benzoic and hippuric acid
2006
Abstract Hippuric acid (HA) in cattle urine acts as a natural inhibitor of soil N2O emissions. As HA concentration varies with diet, we determined critical HA levels. We also tested the hypothesis that the inhibition occurs because the HA breakdown product benzoic acid (BA) inhibits denitrification rates. During a 64-day incubation, we quantified emissions from artificial urine varying in HA, BA and glycine (Gly) concentrations, added to a sandy pasture soil. Increasing HA concentration from 0.4 to 5.6 mmol kg−1 soil significantly decreased the average N2O flux by 54%. At 3.9 mmol kg−1 soil, denitrification levels were 50% reduced for BA as compared to Gly. We conclude that HA inhibits both…
Inulin Derivatives Obtained Via Enhanced Microwave Synthesis for Nucleic Acid Based Drug Delivery
2015
A new class of therapeutic agents with a high potential for the treatment of different socially relevant human diseases is represented by Nucleic Acid Based Drugs (NABD), including small interfering RNAs (siRNA), decoy oligodeoxynucleotides (decoy ODN) and antisense oligonucleotides (ASOs). Although NABD can be engineered to be specifically directed against virtually any target, their susceptibility to nuclease degradation and the difficulty of delivery into target tissues severely limit their use in clinical practice and require the development of an appropriate nanostructured delivery system. For delivery of NABD, Inulin (Inu), a natural, water soluble and biocompatible polysaccharide, wa…
