Multiwavelength observations of polars are essential for developing the big picture of these systems, particularly to gain understanding of the relevant accretion-induced heating and cooling processes. Eclipsing polars are prime targets for such studies since different radiation processes can be disentangled by observations with high-time resolution. We present a preliminary combined analysis of space-based observations (XMM-Newton, ROSAT, HST) with ground-based high-speed photometry (MCCP, OPTIMA, ULTRACAM) of DP Leo, HU Aqr and UZ For. We determine the location and extent of different emission components and find secular and short-term changes in the accretion geometries. We find displaced optical and X-ray emission regions in DP Leo and HU Aqr as well as mini-bursts and accretion arcs of variable size in HU Aqr. We report marked changes in the X-ray eclipse length of UZ For between high and low states.
Anorexia nervosa (AN) is a serious disorder incurring high costs due to hospitalization. International treatments vary, with prolonged hospitalizations in Europe and shorter hospitalizations in the USA. Uncontrolled studies suggest that longer initial hospitalizations that normalize weight produce better outcomes and fewer admissions than shorter hospitalizations with lower discharge weights. This study aimed to compare the effectiveness of hospitalization for weight restoration (WR) to medical stabilization (MS) in adolescent AN.
We performed a randomized controlled trial (RCT) with 82 adolescents, aged 12–18 years, with a DSM-IV diagnosis of AN and medical instability, admitted to two pediatric units in Australia. Participants were randomized to shorter hospitalization for MS or longer hospitalization for WR to 90% expected body weight (EBW) for gender, age and height, both followed by 20 sessions of out-patient, manualized family-based treatment (FBT).
The primary outcome was the number of hospital days, following initial admission, at the 12-month follow-up. Secondary outcomes were the total number of hospital days used up to 12 months and full remission, defined as healthy weight (>95% EBW) and a global Eating Disorder Examination (EDE) score within 1 standard deviation (s.d.) of published means. There was no significant difference between groups in hospital days following initial admission. There were significantly more total hospital days used and post-protocol FBT sessions in the WR group. There were no moderators of primary outcome but participants with higher eating psychopathology and compulsive features reported better clinical outcomes in the MS group.
Outcomes are similar with hospitalizations for MS or WR when combined with FBT. Cost savings would result from combining shorter hospitalization with FBT.
We report secondary eclipse detections of the transiting hot Jupiter WASP-3b at 3.6, 4.5 and 8.0μm using the Spitzer Space Telescope's Infrared Array Camera. We find planet-to-star flux ratios of 0.210+0.043−0.029, 0.281+0.012−0.011 and 0.332+0.050−0.034% in the three bands respectively. Comparisons with 1D atmospheric models show these values strongly favour inefficient redistribution of heat around the planet and also favour the presence of a temperature inversion. In addition, WASP-3 probes the cut-off region of a proposed activity-inversion correlation and we find evidence of atmospheric differences between this system and a similarly active system, WASP-4.
The only non-human primate population in Oceania is on the Island of Ngeaur in the Republic of Palau. This population of macaques, M. fascicularis, was the result of ethnophoresy, the dispersal of animals by humans. German colonialists introduced about a half-dozen macaques from Indonesia around 1909. Islanders view these macaques not only as agricultural pests to be hunted, but also, in a limited sense as an increasing part of their natural heritage. Ngeaur is a useful case study for ethnoprimatology to better understand what causes communities to choose conservation, control, or eradication of commensal macaques, which will be important as human and non-human primate interactions continue to increase around the globe. Ethnoprimatologists can also offer counsel to Palauan communities living near macaques by providing guidance on management strategies. Population surveys of the macaques on Ngeaur have estimated the population to be slightly less than 1,000 individuals, which is twice the size of the human population. This chapter discusses how the local communities can control their macaque population by limiting macaque dispersal into the southern part of Ngeaur where taro gardens are located and onto the other islands of Palau. Totally eradicating the macaques may not be necessary nor economically in Palau's best interest. Dispersal management will be a more cost effective approach than eradication efforts, which can be expensive to implement. Macaques could also be used to draw economic gains from tourism, providing a resource to local communities.
A method for preparation of hollow, biodegradable polymeric microcapsules for use as contrast agents is described, and strategies for their use in concomitant imaging and drug delivery are outlined. Compared with X-ray or magnetic resonance imaging, diagnostic ultrasound is a safe, relatively inexpensive imaging technique, which allows the physician to view real-time images. Contrast agents are being developed which will greatly enhance the contrast of the received image, when injected into the patients blood stream. We have developed hollow polymeric CA based upon the ability to microencapsulate a solid core of ammonium carbonate which is then removed by decomposition and freeze-drying. The polymer poly D,L(lactide-co-glycolide) (PLGA) was chosen for it's FDA approval, and because it has the most rapid in vivo degradation of the α-hydroxy acid series. Spray dried and solvent extraction samples were used to test the concept of concomitant drug delivery and imaging. The method of fabrication had an important effect on the drug loading by adsorption, and on the amount of drug that was released when the capsules were insonated with ultrasound in the medical imaging range. Both were greater for spray dried samples. Both frequency and pressure of insonation also influenced release. The most dramatic increase in release was after 5 minutes for the 10 Mhz low (1.25 MPa) pressure insonation, which showed 316% greater release than control, a total of 1.89 mg.
Glycaemic index (GI) values for fourteen commonly eaten carbohydrate-rich foods processed by various methods were determined using ten healthy subjects. The foods studied were round leaf yellow yam (Dioscorea cayenensis), negro and lucea yams (Dioscorea rotundata), white and sweet yams (Dioscorea alata), sweet potato (Solanum tuberosum), Irish potato (Ipomoea batatas), coco yam (Xanthosoma spp.), dasheen (Colocasia esculenta), pumpkin (Cucurbita moschata), breadfruit (Artocarpus altilis), green banana (Musa sapientum), and green and ripe plantain (Musa paradisiaca). The foods were processed by boiling, frying, baking and roasting where applicable. Pure glucose was used as the standard with a GI value of 100. The results revealed marked differences in GI among the different foods studied ranging from 35 (se 3) to 94 (se 8). The area under the glucose response curve and GI value of some of the roasted and baked foods were significantly higher than foods boiled or fried (P<0·05). The results indicate that foods processed by roasting or baking may result in higher GI. Conversely, boiling of foods may contribute to a lower GI diet.
I am the happiest man alive. I have that in me that can convert poverty into riches, adversity into prosperity, and I am more invulnerable than Achilles; fortune hath not one place to hit me.
Sir Thomas Browne, Religio Medici (1642)
Imagine that one morning your telephone rings and you find yourself speaking with the King of Sweden, who informs you in surprisingly good English that you have been selected as this year's recipient of a Nobel Prize. How would you feel, and how long would you feel that way? Although some things are better than instant celebrity and a significant bank deposit, most people would be hard pressed to name three, and thus most people would probably expect this news to create a sharp and lasting upturn in their emotional lives. Now imagine that the telephone call is from your college president, who regrets to inform you (in surprisingly good English) that the Board of Regents has dissolved your department, revoked your appointment, and stored your books in little cardboard boxes in the hallway. How would you feel, and how long would you feel that way? Losing one's livelihood has all the hallmarks of a major catastrophe, and most people would probably expect this news to have an enduring negative impact on their emotional lives.
Such expectations are often important and often wrong. They are important because people's actions are based in large measure on their implicit and explicit predictions of the emotional consequences of future events.
The most eastward location of the long-tailed macaque, Macaca fascicularis, is on the Island of Ngeaur. The monkey population was estimated to be about 400 in 1994 (Wheatley et al., 1999), a population reduction of about half of the 825–900 estimated by Farslow (1987) in 1981. Ngeaur is one of sixteen States that make up the Republic of Palau. It is a small, 830 ha, raised coral atoll, one of the Republic's 350 islands (Karolle, 1993). This atoll is the only home for monkeys of any kind in the entire Pacific region of Oceania. The 150 people of Ngeaur (Rechad er Ngeaur), however, feel more cursed than blessed by the presence of monkeys. The people of Ngeaur hunt and trap monkeys, although they are not eaten. A previous paper examined the hunting and trapping techniques as well as the behavioral responses of monkeys to hunting (Wheatley et al., 1999). This chapter describes the rationale of the people for their disdain of these monkeys.
This species is a problem to local farmers throughout Southeast Asia (Wheatley, 1999). Despite problems that monkeys can cause, however, some possibilities for their conservation exist (Wheatley, 1999). Balinese conservation efforts at a Monkey Forest in Ubud are a success because the local community of Padangtegal eventually supported them.
