Water jet/spray measurement analysis

The objective of this study was to provide analysis of data obtained under a previous contract entitled Characterization of Drop Spectra from High Volume Flow Water Jets. Measurements of drop spectra were obtained in the spray resulting from the breakup of high volume flow water jets from a variety of nozzle types. The drop spectra measurements were obtained from two drop spectrometers covering a range from 10 microns to 12 millimeters diameter. The task addressed was to select representative spectra from the individual tests and provide analyses in both numerical and graphical formats as outlined in the proposal. The intended application of these results is an evaluation of the feasibility of fog clearing by high volume water sprays. During the tests, a fog event occurred making it possible to test the concept of fog clearing. Visual range data and fog drop spectra were analyzed, with particular emphasis placed on the modification of these parameters due to the water spray

Position paper on the potential of inadvertent weather modification of the Florida Peninsula resulting from neutralization of space shuttle solid rocket booster exhaust clouds

A concept of injecting compounds into the exhaust cloud was proposed to neutralize the acidic nature of the low-level stabilized ground cloud (SGC) was studied. The potential Inadvertent Weather Modification caused by exhaust cloud characteristics from three hours to seven days after launch was studied. Possible effects of the neutralized SGC in warm and cloud precipitation processes were discussed. Based on a detailed climatology of the Florida Peninsula, the risk for weather modification under a variety of weather situations was assessed

Position paper on the potential of inadvertent weather modification of the Florida peninsula resulting from the stabilized ground cloud

Based on the climatology of the Florida Peninsula, we assessed the risk for weather modification. Certain weather situations warrant launch rescheduling because of the risk of possible impact on hurricanes, hail formation and lightning activity, strong wind developments, and intensification of high rainfall rates. The cumulative effects of 40 launches per year on weather modification were found to be insignificant

Factors that influence delivery of tobacco cessation support in general dental practice: A narrative review

Objectives: To review the literature reporting factors that are associated with the delivery of lifestyle support in general dental practice. Methods: A systematic review of the quantitative observational studies describing activities to promote the general health of adults in primary care general dental practice. Behaviour change included tobacco cessation, alcohol reduction, diet, weight management and physical activity. Tooth brushing and oral hygiene behaviours were excluded as the focus of this review was on the common risk factors that affect general health as well as oral health. Results: Six cross sectional studies met the inclusion criteria. Five studies only reported activities to support tobacco cessation. As well as tobacco cessation one study also reported activities related to alcohol usage, physical activity and Body Mass Index. Perceptions of time availability consistently correlated with activities and beliefs about tobacco cessation, alongside the smoking status of the dental professional. Dentists who perceive having more available time were more likely to discuss smoking with patients, prescribe smoking cessation treatments and direct patients towards (signpost to) lifestyle support services. Dental professionals who smoke were less likely to give smoking cessation advice and counselling than non-smokers. Finally, the data showed that professional support may be relevant. Professionals who work in solo practices or those who felt a lack of support from the wider professional team (peer support) were more likely to report barriers to delivering lifestyle support. Conclusion: Organisational changes in dental practices to encourage more team working and professional time for lifestyle support may influence delivery. Dental professionals who are smokers may require training to develop their beliefs about the effectiveness of smoking cessation interventions

Menyelesaikan Konflik Penguasaan Kawasan Hutan melalui Pendekatan Gaya Sengketa Para Pihak di Kesatuan Pengelolaan Hutan Lakitan

Gaya para pihak menghadapi sengketa (conflict style) diperlukan guna penyelenggaraan penyelesaian sengketa yang efektif. Aktor utama dan aktor pendukung serta kepentingan/peran dan pengaruh atau kekuasaan serta hubungannya perlu dipetakan dengan seksama. Apa saja tindakan yang dapat dilakukan untuk menyelesaian konflik berdasarkan gaya para pihak tersebut adalah sesuatu yang perlu dijawab dalam penelitian ini. Dalam penelitian ini gaya para pihak didekati menggunakan analisis gaya bersengketa (AGATA). Studi ini menunjukkan bahwa pihak bergaya sengketa kompromi, akomodasi dan kolaborasi difasilitasi dan dimediasi untuk mengusulkan Hutan Desa, Hutan Kemasyarakatan dan peluang Kemitraan guna mendapatkan legalitas pengeloalan sekaligus pengakuan hutan negara, oleh karena itu penerbitan Ijin Hutan Desa dan Hutan Kemasyarakatan penting dipercepat. Peran pihak luar yang tidak ada hubungan konflik sangat penting untuk memfasilitasi dan memediasi para pihak menuju penyelesaian konflik. Pihak yang berkompetisi perlu dimediasi sehingga gayanya berubah kompromi, akomodasi ataupun kolaborasi. Kalaupun tetap pada gayanya kiranya akan menghasilkan pilihan yang konstruktif untuk memperoleh haknya atas lahan melalui pelepasan kawasan hutan. Pihak yang bergaya menghindar perlu dilakukan komunikasi intensif agar menyadari adanya konflik atau berubah gayanya untuk berkompromi

New Technologies, New Identities, and the Growth of Mass Opposition in the Arab Spring

The recent revolutions known as the Arab Spring have been characterized as the products of social media. However, there is an alternative view that revolution takes place on the street or the battlefield and that the role of social media has been overstated. We argue that some new technologies can serve to facilitate rapid social change when they provide ways to overcome restrictions on the freedoms of expression and association. In doing so, communication technologies enable the formation of new social identities that can challenge existing social orders by promoting the growth of a social movement that is positioned as loyal to the nation and its people but opposed to the government. Our analyses focus on the role of social media in spreading video images of dissent and the links between this video material, satellite television, and mobile telephones in Tunisia and Egypt

Messages of hope: Using positive stories of survival to assist recovery in Rwanda

For the past twenty years, the overriding story of Rwanda has been centred around the events and consequences of the genocide. In Rwanda, public expressions of that story have occurred in the gacaca courts, where survivors and perpetrators testified about their experiences and actions, during ongoing annual remembrance and mourning commemorations, and in memorial sites across the country that act as physical reminders of the genocide. While important as mechanisms for justice, testimony, and commemoration, on their own such events and installations also have the potential to re-traumatise. Accordingly, Rwandan agencies have encouraged a focus on the future as the overarching theme of recent national commemorations. Yet, opportunities for Rwandans to recount and disseminate positive, future-oriented stories of survival and healing remain sparse. Creation and awareness of positive stories have the potential to assist in recovery by increasing feelings of hope and efficacy; and recent research has demonstrated the value of hopefulness, well-being, and social support for vulnerable people. The Messages of Hope program seeks to leverage those ideas into a framework for generating positive messages by Rwandan survivors, providing an opportunity for everyday Rwandans to record and transmit their own positive stories of survival to demonstrate recovery and growth after the genocide, and to reinforce connectedness by sharing their challenges and aspirations. We describe the development and early implementation of this initiative and its potential longer-term application in other contexts of vulnerability

Sepsis in previously healthy neonates discharged home after delivery in Soweto, South Africa

Background. There is a paucity of data on the aetiology of neonatal sepsis in sub-Saharan Africa.Objectives. To investigate the incidence, aetiology and outcomes of physician-diagnosed sepsis in hospitalised neonates who had previously been discharged home after delivery in Soweto, South Africa.Methods. A retrospective review using data abstracted from clinical and laboratory databases identified physician-diagnosed sepsis cases in neonates admitted to the general paediatric wards at Chris Hani Baragwanath Academic Hospital from January 2015 to September 2016. Neonates with physician-diagnosed sepsis were categorised into two groups based on putative pathogens recovered from blood and/or cerebrospinal fluid specimens: (i) culture-confirmed sepsis; and (ii) culture-negative sepsis.Results. Of 1 826 neonatal admissions, 1 025 (56.2%) had physician-diagnosed sepsis: 166 (16.2%) with culture-confirmed sepsis and 859 (83.8%) with culture-negative neonatal sepsis. The commonest pathogens causing culture-confirmed neonatal sepsis were Streptococcus viridans (n=53; 26.5%), S. agalactiae (n=38; 19.0%), and Staphylococcus aureus (n=25; 12.5%). The case fatality rates for culture-confirmed sepsis and culture-negative sepsis were 10.8% (18/166) and 2.6% (22/859), respectively. The odds of death occurring during hospitalisation was 10-fold (95% confidence interval 3.7 - 26.9) higher in neonates with culture-confirmed sepsis compared with culture-negative sepsis.Conclusions. In our setting, physician-diagnosed sepsis represents a huge disease burden in previously healthy neonates hospitalised from home. Most sepsis cases were attributed to S. viridans, S. agalactiae and S. aureus
