Don\u27t talk, don\u27t feel, don\u27t trust

In the United States there are between seven and fifteen million children under the age of eighteen living with at least one parent addicted to alcohol (Berlin, Davis, & Orenstein, 1988; Knight, Vail-Smith, & Barnes, 1992; Roosa, Gensheimer, Short, Ayers, & Shell, 1989; Webb, 1993; Weddle & Wishon, 1986). Alcoholism is a family disease, and every member of the family is affected. The family organizes itself and revolves around the alcoholic, while the needs of other family members are secondary. Plans, rules and feelings change constantly in an attempt to anticipate and placate the alcoholic\u27s drinking behavior (Campbell, 1988; O\u27Rourke, 1992)

Magnetic shielding and vacuum test for passive hydrogen masers

Vibration tests on high permeability magnetic shields used in the SAO-NRL Advanced Development Model (ADM) hydrogen maser were made. Magnetic shielding factors were measured before and after vibration. Preliminary results indicate considerable (25%) degradation. Test results on the NRL designed vacuum pumping station for the ADM hydrogen maser are also discussed. This system employs sintered zirconium carbon getter pumps to pump hydrogen plus small ion pumps to pump the inert gases. In situ activation tests and pumping characteristics indicate that the system can meet design specifications

Chemical Abundances of Planetary Nebulae in M33

Using spectroscopic data presented in Magrini et al. (2003), we have analyzed with the photoionization code CLOUDY 94.00 (Ferland et al. 1998) 11 Planetary Nebulae belonging to the spiral galaxy M 33. Central star temperatures and nebular parameters have been determined. In particular the chemical abundances of He/H, O/H, N/H, Ar/H, and S/H have been measured and compared with values obtained via the Ionization Correction Factors (ICFs) method, when available. Chemical abundance relationships have been investigated; in particular, a correlation between N/H and N/O similar to the Galactic one (Henry 1989), and a feeble anti-correlation between O/H and N/O have been found. A gradient in O/H across the disc of M~33 is indicatively consistent with the one found from HII regions in this galaxy (Vilchez et al 1988). Further studies in the more external parts of M~33 are however needed to ascertain this point. The present result shows that oxygen and helium abundances (with lower accuracy also nitrogen, argon and sulphur) can be actually estimated from the brightest PNe of a galaxy, even if the electron temperature cannot be measured. We also found that the oxygen abundance is quite independent of the absolute magnitude of the PN and consequently the brightest PNe are representative of the whole PN population. This represents an important tool to measure the metallicity of galaxies at the time of the formation of PNe progenitors.Comment: 17 pages, 6 figures, A&A accepte

Histopathological analysis and in situ localisation of Australian tiger snake venom in two clinically envenomed domestic animals

Objective: To assess histopathological changes in clinically envenomed tiger snake patients and identify tissue specific localisation of venom toxins using immunohistochemistry. Samples: One feline and one canine patient admitted to the Murdoch Pet Emergency Centre (MPEC), Murdoch University with tiger snake (Notechis sp.) envenoming. Both patients died as a result of envenomation. Non-envenomed tissue was also collected and used for comparison. Methodology: Biopsy samples (heart, lung, kidney andskeletal muscle tissue) were retrieved 1-2 h post death and processed for histopathological examination using Haemotoxylin and Eosin, Martius Scarlet Blue and Periodic Acid Schiff staining. Tissues were examined by light microscopy and tissue sections subjected to immunohistochemical staining using in-house generated monoclonal and polyclonal antibodies against Notechis venoms. Results: Venom-induced pathological changes were observed in the lungs, kidneys and muscle tissue of both patients. Evidence, not previously noted, of procoagulant venom effects were apparent, with formed thrombi in the heart, lungs (small fibrillar aggregates and larger, discrete thrombi) and kidneys. Immunohistochemical assays revealed venom present in the pulmonary tissue, in and around the glomerular capsule and surrounding tubules in renal tissue and scattered throughout the Gastrocnemius muscle tissue. Conclusion: This work has shown pathological evidence of procoagulant venom activity supporting previous suggestions that an initial thrombotic state occurs in envenomed patients. We have shown that venom toxins are able to be localised to specific tissues, in this case, venom was detected in the lung, kidney and muscle tissues of clinically envenomed animals. Future work will examine specific toxin localisation using monoclonal antibodies and identify if antivenom molecules are able to reach their target tissues

The Local Group Census: planetary nebulae in Sextans B

Five planetary nebulae (PNe) have been discovered in the nearby dwarf irregular galaxy. Emission line images were obtained using the Wide Field Camera of the 2.5m Isaac Newton Telescope (INT) at La Palma (Spain). The candidate PNe were identified by their point-like appearance and relatively strong [OIII] emission-line fluxes. They are located within a galactocentric distance of 2.8 arcmin, corresponding to 1.1 kpc at the distance of Sextans B. Luminosities are in the range 1800--5600Lsolar. Sextans B is one of the smallest dwarf irregular galaxies with a PN population. The number of PNe detected suggest an enhanced star formation rate between 1 and 5 Gyr ago.Comment: 7 pages, 2 figure

Impact of a general practice based group parenting programme on the mental health of children and parents 12 months post intervention : quantitative and qualitative results from a controlled trial

Objective To test the effectiveness at one year of the Webster Stratton Parents and Children Series group parenting programme in a population sample of parents Design multicentre block randomised controlled trial Setting 3 urban General Practices in Oxford. Participants Parents of children aged 2-8 years in 116 families who scored in the upper 50% on a behaviour inventory. Intervention Webster-Stratton’s 10-week parenting programme led by health visitors. Outcome measures. Eyberg Child Behaviour Inventory, Goodman Strengths and Difficulties Questionnaire, General Health Questionnaire, Parenting Stress Index, Rosenberg Self Esteem Scale. Qualitative interviews with volunteer parents from both intervention and control groups immediately post intervention. Results The intervention significantly reduced child behaviour problems and improved mental health at immediate and 6-month follow-ups. One-year differences between control and intervention groups were not significant. Possible methodological reasons for this are: Hawthorne effects and contamination of control group. At interview parents spoke of a need for further sessions and a desire for attendance by both parents. They also described how, as a result of the programme, they had gained in confidence, felt less stressed, shouted less and achieved more cooperation from their children. Conclusions Parenting programmes have the potential to promote mental health and reduce social inequalities, but further work is needed to improve long-term effectiveness

Screening for retinopathy of prematurity in a provincial hospital in Port Elizabeth, South Africa

Background. Retinopathy of prematurity (ROP) is an emerging public health problem in many middle-income countries where improved neonatal survival rates coupled with inadequate health resources have created a new epidemic. There are limited available data on the magnitude of the problem, and screening in South African (SA) hospitals has not been uniformly practised.Objective. To describe the results of various interventions implemented over a 6-year period while developing a new ROP screening service in a provincial hospital in Port Elizabeth, SA.Method. A retrospective case folder review of ROP screening at Dora Nginza Hospital, Port Elizabeth, SA, over the 6-year period 2009 - 2014 was conducted.Results. A total of 919 new cases were seen. Fifteen patients received treatment for type 1 ROP (T1ROP), 223 had type 2 (T2) or earlier ROP, 1 had stage 4 ROP and 6 had stage 5 ROP. The combination of healthcare worker education, improved equipment and human resources and the introduction of dual responsibility for case referrals resulted in an increase in the number of new infants screened from 33 in year 1 to 292 in year 6. The number of infants who were screened late decreased from 33/33 (100%) in year 1, prior to the interventions, to 23/292 in the final year (7.9%). Improved oxygen delivery and adequate oxygen saturation monitoring contributed to a decrease in the incidence of T1ROP from 1.5% to 1% over 1 year and in the incidence of T2 or earlier ROP from 30.3% to 24%.Conclusions. Better management of ROP can be achieved through adequate provision of healthcare professionals and material resources coupled with education and a well-supported referral system. A close working relationship between paediatricians and ophthalmologists results in a more efficient screening programme

Supply assurance in the nuclear fuel cycle

Errata sheet inserted.The economic, technical and political issues which bear on the security of nuclear fuel supply internationally are addressed. The structure of international markets for nuclear fuel is delineated; this includes an analysis of the political constraints on fuel availability, especially the connection to supplier nonproliferation policies. The historical development of nuclear fuel assurance problems is explored and an assessment is made of future trends in supply and demand and in the political context in which fuel trade will take place in the future. Finally, key events and policies which will affect future assurance are identified.U.S. Dept. of Energy Contract no. 426365-S
