Transient analysis of "2 inch Direct Vessel Injection line break" in SPES-2 facility by using TRACE code
2015
In the past few decades a lot of theoretical and experimental researches have been done to understand the physical phenomena characterizing nuclear accidents. In particular, after the Three Miles Island accident, several reactors have been designed to handle successfully LOCA events. This paper presents a comparison between experimental and numerical results obtained for the “2 inch Direct Vessel Injection line break” in SPES-2. This facility is an integral test facility built in Piacenza at the SIET laboratories and simulating the primary circuit, the relevant parts of the secondary circuits and the passive safety systems typical of the AP600 nuclear power plant. The numerical analysis her…
Psychometric properties of the Spanish Burnout Inventory among staff nurses
2015
Accessible summary The burnout syndrome contributes to the deterioration in the quality of personal life as well as lower quality practice in healthcare personnel. Researchers have been concerned about the psychometric limitations of some previous questionnaires designed to evaluate burnout. The Spanish Burnout Inventory was developed to address the problems associated with other instruments, but it has not yet been validated in staff nurses. This study provides evidence that the Spanish Burnout Inventory has adequate psychometric properties to estimate burnout in staff nurses. The Spanish Burnout Inventory offers a theoretical proposal to explain the different components of burnout. The Sp…
“Five Keys to Safer Food” and COVID-19
2021
On 11 March 2020, coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO) and, up to 18:37 a.m. on 9 December 2021, it has produced 268,440,530 cases and 5,299,511 deaths. This disease, in some patients, included pneumonia and shortness of breath, being transmitted through droplets and aerosols. To date, there is no scientific literature to justify transmission directly from foods. In this review, we applied the precautionary principle for the home and the food industry using the known “Five Keys to Safer Food” manual developed by the World Health Organization (WHO) and extended punctually in its core information from five keys, in the light of new…
Recent advances in the application of pulsed light processing for improving food safety and increasing shelf life
2019
Abstract Background New technologies of non-thermal disinfection such as pulsed light (PL) have emerged lately as an alternative to traditional (thermal and chemical) disinfection and preservation methods. PL can be used to decontaminate a great variety of foods as well as to decontaminate contact surfaces, thus improving safety in foods and extending their shelf life. Moreover, this technology can prevent or reduce some of the detrimental effects of traditional methods on nutrients and bioactive compounds of food products. Scope and approach The combination of PL with other techniques such as ultraviolet light (UV), thermosonication (TS), pulsed electric fields (PEF), manothermosonication …
Impacts of volcanic hazards on rural communities and adaptative strategies: A case study of the Virunga Volcanic Province (Democratic Republic of Con…
2023
co auteur étranger; International audience; Active volcanoes are a continuous threat for several regions worldwide and cause socio-economic and environmental issues, including the Virunga Volcanic Province (D.R. Congo). There, more than 2 million people are permanently exposed to the hazards of the most active volcanoes in Africa: Nyiragongo and Nyamulagira. However, there is a clear lack of information regarding the impacts of these hazards and how they may be affected by social vulnerability. In this study, a household survey based on semi-structural interviews was performed for rural communities in Virunga. This research aims to (i) investigate the impacts of volcanic hazards on rural co…
Menancapkan Tiang-Tiang “Kayu Besi”: Adat dan Strategi Para Elit di Kabupaten Teluk Bintuni, Papua Barat
2019
Memperkuat adat bisa bermata dua jika hanya terfokus pada romantisasi “ideologi harmoni†tanpa memeriksa relasi produksi dan kelas dalam masyarakat adat kontemporer. Merespon kebijakan-kebijakan yang dilakukan oleh negara dan investasi, gerakan masyarakat adat di Tanah Papua harus mampu merefleksikan diri dalam hubungan dengan perubahan di internal diri mereka merespon perubahan yang diangkut oleh pembangunan dan investasi. Hanya dengan memahami konteks inilah masyarakat adat di Papua akan mampu untuk mengambil langkah-langkah aksi dalam menegakkan martabatnya.

2018
Artikel ini memfokuskan pada upaya bersama-sama yang dilakukan penulis dengan generasi muda di dua suku yaitu Marori dan Kanum di Kabupaten Merauke, Papua untuk melakukan dokumentasi bahasa dan nilai-nilai budaya mengenai hubungan mereka dengan lingkungannya. Kondisi perubahan sosial budaya menghimpit mereka dan pondasi pengetahuan lokal dalam pemanfaatan lingkunga menjadi tergoyahkan. Masyarakat lokal memiliki pengetahuan kaya yang menunjukkan relasi panjang dengan lingkungan alam sekitarnya. Dari perspektif masyarakat terdapat pemetaan ruang-ruang hidup yang mencakup wilayah perkampungan, perkebunan, dan leluhur (pamali). Masyarakat juga menamai wilayah-wilayah tersebut dengan bahasa loka…
Las interacciones C.T.S. en la enseñanza de las ciencias. Análisis comparativo de la situación para la Física y Química y la Biología y Geología
1995
En trabajos recientes de investigacion en didactica de las ciencias se insiste en la necesidad de introducir las relaciones Ciencia, Tecnologia y Sociedad (CTS) en la ensenanza de las ciencias. En este articulo se constata que en nuestro pais dichas relaciones estan practicamente ausentes en los libros de texto cientificos. Esto contribuye a que los estudiantes tengan una imagen de la ciencia alejada del mundo real, poco relacionada con el desarrollo tecnologico y sus consecuencias en el medio ambiente y la sociedad. Por otra parte, se observan diferencias en el interes de los estudiantes hacia la Fisica y Quimica y la Biologia y Geologia.
Pensamiento débil y reforma educativa: la racionalidad bajo el signo de las apariencias

La educación social en el ámbito penitenciario
1995
Los autores proponen el modelo cientifico-tecnologico como un modelo apropiado desde el cual enfrentarse a cuestiones pedagogico-sociales. Las consecuencias practicas que se derivan de la adopcion de la perspectiva tecnologica, asi como la especificidad del medio penitenciario son algunos de los temas centrales del capitulo, que finaliza con una apuesta clara a favor de la intervencion socioeducativa como instrumento valido en la rehabilitacion de los sujetos delincuentes.
