Mothers who killed or attempted to kill their child: life circumstances, childhood abuse, and types of killing.
1999
The objectives of the present study were to examine the life circumstances, childhood abuse, and types of homicidal acts of 48 mothers who killed/attempted to kill their children) under age 12 between 1970-96 in Finland. Data on the mothers’ life stresses, psychological problems, and childhood abuse were collected from mental state examination (MSE) reports. The cases were divided into 15 neonaticides and 33 mothers who killed an older child. Childhood abuse was documented in 63% of the mothers’ MSE reports. Qualitative analysis identified neonaticides, joint homicide-suicide attempts, impulsive aggression, psychotic acts, postpartum depression, and abusive acts. Nonlinear principal compone…

Treatment of high strength industrial wastewater with membrane bioreactors for water reuse: Effect of pre-treatment with aerobic granular sludge on s…
2019
Abstract In this study, the treatment of citrus wastewater with membrane bioreactors (MBRs) under different configurations was investigated for water reuse. In particular, one MBR and one aerobic granular sludge MBR (AGS + MBR) bench scale plants were operated for 60 days. The experimental campaign was divided into two periods. In Phase I, a conventional hollow fiber MBR was employed for the treatment of the raw high strength wastewater, whereas in Phase II a combination of in-series reactors (AGS + MBR) was adopted for the treatment of the high strength citrus wastewater The results demonstrated that both plant configurations enabled very high COD removal, with average values close to 99%.…
Occupational Safety and Health Risk Assessment in Engineered Nanoparticles Manufacturing Processes
2017
The engineered nanoparticles are more and more entering in Romanian working places, both in research laboratories and in manufacturing processes. Ever increasingly numerous evidence shows that this materials science revolution can generate significant health, safety and environmental hazards, in addition to the social, economic and ethical challenges involvedBased on the precautionary principle recommended be the European Union and a thorough literature review, this research is intended to introduce a framework for further development of an Occupational Health and Safety risk management foundation in this field of concern. Starting from a systematic approach in terms of occupational exposur…
A questionnaire to assess parental perception of barriers towards active commuting to school (PABACS): Reliability and validity
2019
Abstract Introduction Parental barriers are a key factor to determine physical activity behaviors, such as active commuting to school in young people. The purpose of this study was to test the reliability and validity of a questionnaire which addresses parental barriers towards active commuting to school. Methods This paper describes the development, following the Delphi method, and the validation of a Likert-scale questionnaire of 23 items (Parental Perception of Barriers towards Active Commuting to School (PABACS)) designed to determine the main parental barriers. These barriers are categorized into 3 scales (general, walking, and cycling barriers) and the overall questionnaire. A total o…

Comparison between Different Dynamic Reconfigurations of Electrical Connections for partially shaded PV Modules
2018
This paper presents an economical investigation on the benefits related to the employment of reconfiguration systems for photovoltaic plants. More in detail, different structures of reconfigurators are proposed and, in order to evaluate the economical convenience on their installation, the Net Present Value is used as a validation element. Significant results are carried out from the proposed analysis.
Thermal and non-thermal preservation techniques of tiger nuts' beverage "horchata de chufa". Implications for food safety, nutritional and quality pr…
2017
"Horchata de chufa" is a traditional Spanish beverage produced from tiger nuts (Cyperus esculentus L.). Due to its richness in nutritional compounds, it is highly perishable and its conservation by pasteurization and/or adding preservatives is required. Although efficient, conventional thermal treatment for pasteurization induces changes in the nutritional and sensory properties. Replacing conventional pasteurization by non-thermal technologies such as pulsed electric fields, ultraviolet, and high pressure, combined with moderate temperatures (<40°C) allows a reduction of energy consumption, along with the preservation of the most thermo-sensitive molecules. Accordingly, this review deals w…
Application of White Mustard Bran and Flour on Bread as Natural Preservative Agents.
2021
In this study, the antifungal activity of white mustard bran (MB), a by-product of mustard (Sinapis alba) milling, and white mustard seed flour (MF) was tested against mycotoxigenic fungi in the agar diffusion method. The results obtained were posteriorly confirmed in a quantitative test, determining the minimum concentration of extract that inhibits the fungal growth (MIC) and the minimum concentration with fungicidal activity (MFC). Since MF demonstrated no antifungal activity, the MB was stored under different temperature conditions and storage time to determine its antifungal stability. Finally, an in situ assay was carried out, applying the MB as a natural ingredient into the dough to …
Performance of a historical cantilever reinforced concrete bridge with half-joint degradation
2022
The lack of maintenance of roadway concrete bridges built from the Second World War until the 70 s of the 20th century has led in recent years to an ever-increasing request for safety assessments. When bridge performance in terms of Serviceability Limit State (SLS) and Ultimate Limit State (ULS) has to be evaluated, in-situ visual inspections and load tests for safety and maintenance assessment have to be coupled with structural analysis. In order to identify a sound bridge structural model and to assess the actual conservation state, more refined models than those usually considered for section and reinforcement design should be used to reproduce the results of load tests and perform globa…
