Modelling the atomic structure of very high-density amorphous ice

The structure of very high-density amorphous (VHDA) ice has been modelled by positionally disordering three crystalline phases, namely ice IV, VI and XII. These phases were chosen because only they are stable or metastable in the region of the ice phase diagram where VHDA ice is formed, and their densities are comparable to that of VHDA ice. An excellent fit to the medium range of the experimentally observed pair-correlation function g(r) of VHDA ice was obtained by introducing disorder into the positions of the H2O molecules, as well as small amounts of molecular rotational disorder, disorder in the O--H bond lengths and disorder in the H--O--H bond angles. The low-k behaviour of the experimental structure factor, S(k), is also very well reproduced by this disordered-crystal model. The fraction of each phase present in the best-fit disordered model is very close to that observed in the probable crystallization products of VHDA ice. In particular, only negligible amounts of ice IV are predicted, in accordance with experimental observation.Comment: 4 pages, 3 figures, 1 table, v2: changes made in response to referees' comments, the justification for using certain ice phases is improved, and ice IV is now disordered as wel

Cash management practices in Louisiana municipalities

In this paper, we examine the cash management practices in the State of Louisiana and contrasted those practices with the rate of return on investment income due to cash management practices. Essentially, we framed various model hypotheses from the literature, which tells us that if those practices exist then we should see an increased rate of return due to cash management. In general, our research supported the literature but there were some interesting exceptions that merit attention

Re National Harbours Board and Public Service Alliance of Canada

Employee Grievance alleging unjust discharge. AWARD: Employee grievance alleging breach of a collective agree­ment between the parties dated August 15, 1973, in that the grievor was discharged without just cause because the medical reasons for his discharge are not supported by the evidence. At the hearing it was also argued on behalf of the grievor, that his grievance should be allowed because he did not receive fair notice of the grounds upon which his employ­ment was terminated. The grievor requests that he be rein­stated in his position as constable with the National Harbour Police, with full pay and benefits retroactive to the date of his release. He further requests that all reference to this action be purged from the National Harbours Board\u27s and Government\u27s files

What factors influence healthcare professionals to refer children and families to paediatric psychology?

Objectives: This study aimed to investigate factors influencing referral of children with physical illness to paediatric psychology. Due to high rates of mental health problems within this population, studies have shown that referral to paediatric psychology should be increased. However, few studies have examined factors shaping healthcare professionals’ referral behaviour. Methods: The current study used the theory of planned behaviour to develop a questionnaire which explores factors influencing the referral of children and families to paediatric psychology. Psychometric properties of the questionnaire were examined. Results: The questionnaire was found to have good reliability and validity. The main constructs of the theory of planned behaviour were useful in predicting intention to refer to paediatric psychology. Specific beliefs about referral were shown to influence intention to refer. Conclusions: Findings suggest that individual attitudes and beliefs can impact healthcare professionals’ referral behaviour, indicating that multidisciplinary interventions and inter-professional education relating to the psychological aspects of illness are required

: Background. Basic life support (BLS) is an emergency act to release or opened anairway, breathing and to help on maintain blood circulation without using devices. Which includes of BLS resuscitation or CPR (CPR) were is include of emergency measure, as an effort to restore a state of respiratory and cardiac arrest, to prevent to a condition which is call biological death.Purpose. To determine the influence of basic life support training to the knowledge of resuscitation on students at SMA Negeri 1 Toili.Method. The research using study praexperimental design One-Group Pre-test post-test design to compare the knowledge of CPR before and after the training. Samples used 72 sample which isconsisting of 37 members and 35 members of PMR scout. Data analyzusing Wilcoxon Signed Rank Test.Results.

Statistically there's significant effect of training on the theory of basic life support CPR knowledge students at SMA Negeri 1 Toili

Practices of strength and conditioning coaches: a snapshot from different sports, countries and expertise levels

This study describes the practices of strength and conditioning coaches (SCCs) from different sports, countries and expertise levels. One-hundred and fifty-six SCCs (31.9 + 8.9 years old) completed an online survey, consisting of 40 questions (36 fixed response and 4 open-ended), with eight sections: (a) background information, (b) muscular strength and power development, (c) speed development, (d) plyometrics, (e) flexibility development, (f) physical testing, (g) technology use, and (h) programming and any additional comments. Responses were received from 48 sports and 17 countries. This study provides exploratory evidence incorporating responses primarily in soccer (45%), track and field (30%), volleyball (23%), golf (17%) and tennis (17%). A Bachelor’s degree or higher were held by 99% of SCCs, of which 94% were in a sports science related field, and 71% held a strength and conditioning related certification or accreditation. Periodization strategies and physical testing were used by 94% of SCCs. The hang clean (82%), power clean (76%), and clean high pull (63%) were the most commonly prescribed Olympic Weightlifting exercises. Multiple hops/lunges (84%) were the most commonly prescribed plyometrics exercises. For open ended questions, 40% of SCCs wanted to integrate more technology into their programs, whereas, 30% of coaches believed technology will be the main future trend in strength and conditioning. SCCs from different sports, countries and expertise levels can use the information presented in this study to review their current practices and potentially provide a source of new ideas for diversifying or modifying future practices too
