international industry practice on power quality monitoring
2014Co-Authors: Jovica V. Milanovic, Math Bollen, Jan Meyer, R F Ball, W Howe, Robin Preece, Sean Elphick, Ninel CukalevskiAbstract:Monitoring of voltages and currents at system buses gives the network operators information about the performance of their network, both for the system as a whole and for individual locations and customers. There is also demand from the customers and the regulatory agencies to provide information on the actual power-quality (PQ) level. Developments in enabling technology have made it possible to monitor at a large scale and to record virtually any PQ parameter of interest. While many network operators are installing monitoring equipment and while more and more monitors are available, there is a lack of knowledge and agreement on a number of aspects of the monitoring process and on processing the recorded data. As a response to this lack of uniformity in approach, data acquisition, and processing, in February 2011, CIGRE and CIRED established the Joint Working Group C4.112: “Guidelines for Power quality monitoring-measurement locations, processing and presentation of data.” In order to identify the current international industry practice on PQ monitoring, the Group carried out a survey in 43 countries across the world. This paper summarizes the key findings from 114 responses to the questionnaire and identifies prevalent industrial practice in PQ monitoring around the world.

decontamination of breast pump milk collection kits and related items at home and in hospital guidance from a Joint Working Group of the healthcare infection society and infection prevention society
2016Co-Authors: E Price, G Weaver, P Hoffman, M Jones, J Gilks, V Obrien, G RidgwayAbstract:Summary Introduction A variety of methods are in use for decontaminating breast pump milk collection kits and related items associated with infant feeding. This paper aims to provide best practice guidance for decontamination of this equipment at home and in hospital. It has been compiled by a Joint Working Group of the Healthcare Infection Society and the Infection Prevention Society. Methods The guidance has been informed by a search of the literature in Medline, the British Nursing Index, the Cumulative Index to Nursing and Allied Health Literature, Midwifery and Infant Care, and the results of two surveys of UK neonatal units in 2002/3 and 2006, and of members of the Infection Prevention Society in 2014. Since limited good quality evidence was available from these sources, much of the guidance represents good practice based on the consensus view of the Working Group. Key recommendations –Breast pump milk collection kits should not be reused by different mothers unless they have been sterilized in a sterile services department between these different users. –When used by the same mother, a detergent wash followed by thorough rinsing and drying after each use gives acceptable decontamination for most circumstances, as long as it is performed correctly. –Additional decontamination precautions to washing, rinsing and drying may be used if indicated by local risk assessments and on advice from the departmental clinicians and infection prevention and control teams. The microbiological quality of the rinse water is an important consideration, particularly for infants on neonatal units. –If bottle brushes or breast/nipple shields are used, they should be for use by one mother only. Decontamination should be by the processes used for breast pump milk collection kits. –Dummies (soothers, pacifiers or comforters) needed for non-nutritive sucking by infants on neonatal units should be for single infant use. Manufacturers should provide these dummies ready to use and individually packaged. They must be discarded at least every 24h or immediately if soiled with anything other than the baby's saliva. No attempt should be made to decontaminate the dummies, either before or during use. Conclusion This guidance provides practical recommendations to support the safe decontamination of breast pump milk collection kits for healthcare professionals to use and communicate to other Groups such as parents and carers.

the emergence of zika virus as a global health security threat a review and a consensus statement of the indusem Joint Working Group jwg
2016Co-Authors: Veronica Sikka, Sagar Galwankar, Stanislaw P Stawicki, Vijay Kumar Chattu, Raaj K Popli, Dhanashree S Kelkar, Stanley G Sawicki, Thomas J PapadimosAbstract:The Zika virus (ZIKV), first discovered in 1947, has emerged as a global public health threat over the last decade, with the accelerated geographic spread of the virus noted during the last 5 years. The World Health Organization (WHO) predicts that millions of cases of ZIKV are likely to occur in the Americas during the next 12 months. These projections, in conjunction with suspected Zika-associated increase in newborn microcephaly cases, prompted WHO to declare public health emergency of international concern. ZIKV-associated illness is characterized by an incubation period of 3-12 days. Most patients remain asymptomatic (i.e., ~80%) after contracting the virus. When symptomatic, clinical presentation is usually mild and consists of a self-limiting febrile illness that lasts approximately 2-7 days. Among common clinical manifestations are fever, arthralgia, conjunctivitis, myalgia, headache, and maculopapular rash. Hospitalization and complication rates are low, with fatalities being extremely rare. Newborn microcephaly, the most devastating and insidious complication associated with the ZIKV, has been described in the offspring of women who became infected while pregnant. Much remains to be elucidated about the timing of ZIKV infection in the context of the temporal progression of pregnancy, the corresponding in utero fetal development stage(s), and the risk of microcephaly. Without further knowledge of the pathophysiology involved, the true risk of ZIKV to the unborn remains difficult to quantify and remediate. Accurate, portable, and inexpensive point-of-care testing is required to better identify cases and manage the current and future outbreaks of ZIKV, including optimization of preventive approaches and the identification of more effective risk reduction strategies. In addition, much more work needs to be done to produce an effective vaccine. Given the rapid geographic spread of ZIKV in recent years, a coordinated local, regional, and global effort is needed to generate sufficient resources and political traction to effectively halt and contain further expansion of the current outbreak.

the 2015 academic college of emergency experts in india s indo us Joint Working Group white paper on establishing an academic department and training pediatric emergency medicine specialists in india
2015Co-Authors: Prashant Mahajan, Sagar Galwankar, Prerna Batra, Binita R Shah, Abhijeet Saha, Praveen Aggrawal, Ameer Hassoun, Bipin Batra, Sanjeev Bhoi, Om Prakash KalraAbstract:The concept of pediatric emergency medicine (PEM) is virtually nonexistent in India. Suboptimally organized prehospital services substantially hinder the evaluation, management, and subsequent transport of the acutely ill and/or injured child to an appropriate facility. Furthermore, the management of the ill child at the hospital level is often provided by overburdened providers who, by virtue of their training, lack experience in the skills required to effectively manage pediatric emergencies. Finally, the care of the traumatized child often requires the involvement of providers trained in different specialities, which further impedes timely access to appropriate care. The recent recognition of Doctor of Medicine in Emergency Medicine as an approved discipline of study as per the Indian Medical Council Act provides an unprecedented opportunity to introduce PEM as a formal academic program in India. PEM has to be developed as a 3 year superspeciality course after completion of MD Diplomate of National Board (DNB) Pediatrics or MD DNB in EM. The National Board of Examinations that accredits and administers postgraduate and postdoctoral programs in India also needs to develop an academic program DNB in PEM. The goals of such a program would be to impart theoretical knowledge, training in the appropriate skills and procedures, development of communication and counseling techniques, and research. In this paper, the Joint Working Group of the Academic College of Emergency Experts in India (JWG ACEE India) gives its recommendations for starting 3 year DM DNB in PEM, including the curriculum, infrastructure, staffing, and training in India. This is an attempt to provide an uniform framework and a set of guiding principles to start PEM as a structured superspeciality to enhance emergency care for Indian children.

on the discovery of new elements iupac iupap report report of the 2017 Joint Working Group of iupac and iupap
2020Co-Authors: Sigurd Hofmann, Sergey N Dmitriev, C Fahlander, J M Gates, J B Roberto, H SakaiAbstract:Almost thirty years ago the criteria that are currently used to verify claims for the discovery of a new element were set down by the comprehensive work of a Transfermium Working Group, TWG, Jointly established by IUPAC and IUPAP. The recent completion of the naming of the 118 elements in the first seven periods of the Periodic Table of the Elements was considered as an opportunity for a review of these criteria in the light of the experimental and theoretical advances in the field. In late 2016 the Unions decided to establish a new Joint Working Group, JWG, consisting of six members determined by the Unions. A first meeting of the JWG was in May 2017. One year later this report was finished. In a first part the works and conclusions of the TWG and the Joint Working Parties, JWP, deciding on the discovery of the now named elements are summarized. Possible experimental developments for production and identification of new elements beyond the presently known ones are estimated. Criteria and guidelines for establishing priority of discovery of these potential new elements are presented. Special emphasis is given to a description for the application of the criteria and the limits for their applicability. (Less)
