Immediate one-step lime precipitation and atmospheric carbonation as pre-treatment for low biodegradable and high nitrogen wastewaters: A case study of explosives industry

The aim of this article is to furnish insights of the Italian public debate on the recognition of LGBTQ rights, which can be understood as an interesting case study of the complex relationship between (multi)secularisation processes and re/definition of citizenship models. More specifically, the article analyses two political events related to this debate that took place in Rome in June 2015. The first is the Family Day demonstration, promoted by conservative Catholic groups; the second is the LGBTQ Pride parade, promoted by various gay, lesbian and transsexual/gender associations. We analyse the official statements issued by the two organising committees of the demonstrations, adopting the framework and methods of the Critical Discourse Analysis. Above and beyond an evident political conflict between the two discourses, we try to shed light on their mutual construction on the basis of what we call ‘naturalization’ and ‘universalization’ processes.

Observational Design

Background: Patient safety is an indicator of hospital service quality. A hospital in Surabaya identified six indicators of patient safety goals. There are two indicators which can not achieve the standard, namely effective communication and infection risk reduction.Aims: This study aims to identify the process improvement that can be done to increase indicator performance by using PDSA cycle.Method: A descriptive observational design was used in this study with a case study and participatory approach. There were 5 subjects selected by purposive sampling. Interview and observation were used to collect data that then were analyzed descriptively. The validity of data was done by triangulation of method, source, and theory.Results: The PDSA results indicated that the cause of the poor indicators performance of both patient safety goals is the poor compliance of the health staffs in carrying out read-back procedure and hand hygiene as written in SOP. It was caused by the lack of knowledge and motivation of the health staffs in implementing the SOP.Conclusion: In conclusion, process improvement can be done by socializing read-back SOP and hand hygiene as well as supervision conducted periodically by managers. Plan stage is one step which should be improved. Commitment in implementing the improvement planning is necessary. In addition, further research on factors that influence compliance should be conducted.Keywords: patient safety, PDSA method, process improvement, quality of hospital

Keywords: vanadium pentoxide；carbon black；reduction and nitridation；vanadium nitrogen alloy. Abstract. The V2O5 extracted from low vanadium shale and carbon black are used as raw materials to prepare briquetting samples through mixing, grinding and pressing. The samples are prereduced, final reduced and nitrated to produce vanadium nitrogen alloy with high nitrogen content. Thermodynamic analysis and experiment results show that：（1）In order to avoid V2O5 volatilization loss during reduction, the briquetting samples should be pre-reduced for 4 hours below the melting point 670°C of V2O5, which can transform V2O5 into low valence vanadium oxide.（2）During V2O5 being self-reduction under N2 atmosphere, if the final reduction temperature is below 1271°C, the VN is preferential formation; if more than 1271°C, the reduced product forms V4C3.（3）To make a product with high nitrogen and low carbon content, the final reduction and nitride temperature should be controlled below 1300°C.

Pre Treatment

Experiments were performed to determine the influence of various dehydration and vitrification treatment times on the ‘one-step freezing’ cryopreservation of embryonic axes (EAs), composed of zygotic embryos and cotyledon residuals, from mature seeds of a Georgian provenance of chestnut (Castanea sativa Mill.). Dehydration was carried out in laminar flow hood from 1 to 5 h, and vitrification experiments were carried out by immersion of EAs in PVS2 vitrification solution up to 120 min, both followed by direct immersion in liquid nitrogen. Both systems resulted in inducing specimen tolerance to ultra-rapid freezing, although to a different extent. Full germination of cryo-stored EAs after 5 h of dehydration (reducing moisture content from initial 66% to 21%) has been increased from 0% to 66.7%. A pre-treatment of EAs in PVS2 vitrification solution for 30 min produced fully developed plantlets at a rate of 55.6% in post-cryopreservation. Plantlet regrowth from cryopreservation was faster in EAs that underwent the dehydration/‘one-step freezing’ procedure. All the plantlet from cryopreserved EAs could be easily acclimatized, producing healthy potted plants. Finally, the TTC test showed to be useful for a fast evaluation of specimen survival after thawing and, as a consequence, to speed up the development of optimized cryo-protocols. ********* In press - Online First.

Desalination Technology

This chapter gives an overview about reverse osmosis membrane desalination technology and process. Desalination process can be considered as one of the crucial processes in obtaining fresh water to meet the increasing fresh water demand throughout the world. Desalination process begins with the intake of seawater or brackish water. The intake system usually comprises a pump and piping system. Then, the seawater goes through pre-treatment process. From there, the treated seawater will go through desalination process. The most widely used desalination is membrane desalination utilizing reverse osmosis membrane. After desalination process, the fresh water will go through more filtration and a series of post-treatment. Post-treatment consists of conditioning and stabilizing the water for distribution. This chapter concludes with a case study to illustrate the operation and sustainability of a small-scale desalination plant that utilizes brackish city polluted water as source.

Abstract Background There is substantial interest among scholars in digital platforms and the ecosystems around them. Digital platforms are open, continuously evolving, sociotechnical structures that can be sensitive to various changes. Aim We take one-step further and investigate the post-dominance phase of platforms. The electronic identification (eID) ecosystem in Finland provides a good example of ecosystem transformation due to external changes from EU and national regulation. Method We engage in an extensive case study of a nation-wide monopolistic eID platform. We first take a retrospective view to understand the historical context and then examine in detail how an external driver leads to changes in the ecosystem. Results We explicate the platform evolution process, from a phase of dominance with centralized control structures to a more federated governance approach. We find that the introduction of intermediaries between the platform and its users contributes to a weakening of the dominant platform owners. Conclusion This finding that platforms can transform into industry infrastructures has an important implication for our understanding of the dynamics underlying digital platforms.
