Objective: An in vitro study was made to compare mean thermal variation according to the material, design and wear of the surgical drills used during dental implant site preparation. Material and methods: Three study groups (stainless steel drills with straight blades
Large-scale radiation manufacturing of hierarchically assembled nanogels
2012
Nanogels (NGs), or small particles formed by physically or chemically crosslinked polymer networks, represent a niche in the development of "smart" nanoparticles for drug delivery and diagnostics. They offer unique advantages over other systems, including a large and flexible surface for multivalent bio-conjugation; an internal 3D aqueous environment for incorporation and protection of (bio)molecular drugs; the possibility to entrap active metal or mineral cores for imaging or phototherapeutic purposes; stimuli-responsiveness to achieve temporal and/or site control of the release function and biocompatibility. The availability of inexpensive and robust preparation methodologies is at the ba…
Il diportismo nautico e le attività economiche in Sardegna
2013
Operating in a complex globalized world, tourism destinations are continuously challenged to improve their performance in order to stay competitive in a dynamic environment they have to identify new potential markets, to develop networks, clusters and new products. Today the current forms of tourims that are emerging request to spend leisure time as actively as possible and the development of niche tourism with these characteristics can represent a sustainable development strategy for destinations ...
Performance Evaluation for a Sustainable Supply Chain Management System in the Automotive Industry Using Artificial Intelligence
2020
Increasing the sustainability of a system can be achieved by evaluating the system, identifying the issues and their root cause and solving them. Performance evaluation translates into key performance indicators (KPIs) with a high impact on increasing overall efficacy and efficiency. As the pool of KPIs has increased over time in the context of evaluating the supply chain management (SCM) system&rsquo
Influence of torrefaction pretreatment on the pyrolysis of Eucalyptus clone: A study on kinetics, reaction mechanism and heat flow
2016
Abstract The adverse nature of biomass requires specific pretreatment processes to better utilize it in bioenergy applications, and torrefaction is one of the most recognized thermal pretreatment methods. In this regard, we studied the effect of torrefaction pretreatment on kinetics, reaction mechanism and heat flow during the pyrolysis of biomass by making a comparative analysis between the pyrolysis of dried and torrefied Eucalyptus wood. Torrefied biomass was produced at three temperatures, namely 250, 275 and 300 °C. Pyrolysis was performed at 700 °C. The char yield during pyrolysis increased from 22.39 percent to 36.34 percent when the torrefaction temperature was increased from 250 to…
Efficiency of Daphnia magna in removal of green microalgae cultivated in Nordic recirculating aquaculture system wastewater
2020
The increase of global aquaculture production has boosted the development of recirculating aquaculture systems not only because they reduce water use but also provide opportunities for waste management and the use of released nutrients. The dissolved nutrients can be efficiently removed from recirculating aquaculture system wastewater by microalgae, and microalgae can be harvested from the wastewater with low costs by zooplankton such as Daphnia. The purpose of this study was to evaluate the feasibility of using microalgae and Daphnia for bioremediation of recirculating aquaculture system wastewater in Nordic conditions. We evaluated the growth and filtration efficiency of the waterflea Dap…
Effects of Job Content and Physical Activity on Body Mass Index among Obese Managers of the Mexican Manufacturing Industry
2020
Mental health disorders resulting from work stressors are increasing in the Mexican manufacturing industry and worldwide. Managerial positions in these contexts are highly stressful, and although physical activity may reduce the negative effects of work stress, the relationships between these two aspects regarding their effects on the body mass index (BMI) of obese managers are scarcely studied. This article aims to study such relationships by using the Job Content Questionnaire (JCQ) dimensions with the Baecke’s physical activity questionnaire dimensions and analyzing their effects on the BMI. A sample of 255 managers from the Mexican industry, with a (BMI > 30) participated by answerin…
The Relationship Between the Burnout Syndrome Dimensions and Body Mass Index as a Moderator Variable on Obese Managers in the Mexican Maquiladora Ind…
2021
Burnout syndrome (BS) and obesity are two growing conditions that affect employees’ health and company productivity. Recently, several studies have pointed to a possible relationship between both phenomena. However, such a relationship has not been clearly defined. This research analyzes the relationship between BS dimensions and body mass index (BMI), the latter being treated as a moderator variable among obese senior and middle managers in the Mexican maquiladora industry through a structural equation model. A total of 361 senior and middle managers (124 of them classified as obese under the World Health Organization’s criteria) completed both the Maslach Burnout Inventory-General Survey …

Ražošanas izmaksas un faktori, kas tās ietekmē, galvenokārt naftas un gāzes uzņēmumos Uzbekistānā
2021
Produkta cenu veidošanās ķēdē vissvarīgākā un būtiskākā loma ir ražošanas izmaksām, tas ir sākumpunkts, kur sākas produkta cenas veidošanās, kas cenu noteikšanā iet cauri tālākiem posmiem, līdz nonāk nonācēju rokās. klients vai patērētājs. Kā tādu nevar uzsvērt nozīmi, kāda ir ražošanas izmaksām un faktoriem, kas tās ietekmē. Uzņēmumi ražošanas izmaksu aprēķināšanai izmanto dažādus modeļus atkarībā no nozares, uzņēmuma lieluma, ieguldījumiem un vēlamajiem rezultātiem. Tā kā naftas un gāzes nozare ir ļoti specializēta un reti korelē ar citām nozarēm, šis pētījums izvirzīja mērķi izpētīt ražošanas izmaksu veidošanas veidu, izmantojot vienu no naftas un gāzes uzņēmumiem. Šajā darbā tika veikts…
