A Spin-Orbit Alignment for the Hot Jupiter HATS-3b

We have measured the alignment between the orbit of HATS-3b (a recently discovered, slightly inflated Hot Jupiter) and the spin-axis of its host star. Data were obtained using the CYCLOPS2 optical-fiber bundle and its simultaneous calibration system feeding the UCLES spectrograph on the Anglo-Australian Telescope. The sky-projected spin-orbit angle of $\lambda = 3\pm25^{\circ}$ was determined from spectroscopic measurements of Rossiter-McLaughlin effect. This is the first exoplanet discovered through the HATSouth transit survey to have its spin-orbit angle measured. Our results indicate that the orbital plane of HATS-3b is consistent with being aligned to the spin axis of its host star. The low obliquity of the HATS-3 system, which has a relatively hot mid F-type host star, agrees with the general trend observed for Hot Jupiter host stars with effective temperatures $>6250$K to have randomly distributed spin-orbit angles.Comment: 13 pages.

A systematic review of therapeutic options for non-conductive olfactory dysfunction

Background: Olfactory dysfunction affects a significant proportion of the population but appears to be more common in the elderly population (>20% of adults over 60 years old). Unfortunately, many sufferers face an apparent lack of therapeutic options when consulting with medical professionals. Method: We searched various electronic medical databases for the treatment of non-conductive olfactory dysfunction. After careful review of the abstracts and the full articles, we included publications that fulfilled our inclusion criteria and analysed the results. Results: A total of 38 publications were included in our review including 6 randomised control trials, 14 cohort studies and 18 observational studies. Conclusion: Olfactory training appears to improve non-conductive olfactory dysfunction irrespective of the aetiology. Steroids appear to have some benefit, but this may be aetiology dependent and Vitamin A and sodium citrate have shown some promise. High quality randomised control trials are still required to determine their place in managing this patient population

Self-enforcing Union Contracts: Efficient Investment and Employment

Baldwin (1983) asks whether a firm can credibly deter union opportunism that would lead to underinvestment. We show that the punishments Baldwin considers credible exclude tougher threats that only have the appearance of being self-destructive. If the firm\u27s discount factor is sufficiently close to one, union opportunism can indeed be deterred. Moreover, we show that given the firm\u27s discount factor, a shorter lifetime of capital does not necessarily promote efficiency. Although, as Baldwin emphasizes, it does enhance the firm\u27s ability to punish union opportunism, it also creates adverse incentives for the firm to engage in opportunistic employment cuts

Nondisclosure as a Contract Remedy: Explaining the Advance-notice Puzzle

Prior theoretical work predicts an underprovision of advance-notice contracts stemming from their enforcement costs. In the present model, it is rather the fundamental inability of workers to alienate their right to quit taken in conjunction with parameters central to job separation decisions that jointly determine the mix of notice and no-notice contracts observed in equilibrium. Not all equilibrium contracts are efficient, but there is no underprovision of notice. Mandating notice cannot improve on joint value and indeed may reduce it. Furthermore, although a mandate can be merely redistributive, there are cases in which it harms all parties

A Nearly Polar Orbit for the Extrasolar Hot Jupiter WASP-79b

We report the measurement of a spin-orbit misalignment for WASP-79b, a recently discovered, bloated transiting hot Jupiter from the WASP survey. Data were obtained using the CYCLOPS2 optical-fiber bundle and its simultaneous calibration system feeding the UCLES spectrograph on the Anglo-Australian Telescope. We have used the Rossiter-McLaughlin effect to determine the sky-projected spin-orbit angle to be lambda = -106+19-13 degrees. This result indicates a significant misalignment between the spin axis of the host star and the orbital plane of the planet -- the planet being in a nearly polar orbit. WASP-79 is consistent with other stars that have Teff > 6250K and host hot Jupiters in spin-orbit misalignment.Comment: 8 pages, 2 figures, in press ApJL (accepted 2 August 2013

Intrauterine retained fetal bones as a cause of secondary infertility

Three cases of retained fetal bones, the first two after mid-trimester termination of pregnancy and the third after dilatation and evacuation (D&E) of the uterus for a missed abortion, are presented. All the cases were complicated by secondary infertil-ity. In all the cases the diagnosis was confirmed by a high resolution pelvic ultrasound scan. The pieces of bones were removed at dilatation and evacuation under general anaesthesia. In two of the cases pregnancy occurred within 6 months of re-moval of the bones. It is believed that bones re-tained freely in the endometrial cavity behave as an intrauterine contraceptive device (IUCD). Be-cause of the many complications associated with mid-trimester dilatation and evacuation of the uterus, its role in modern gynaecology should be limited. It is suggested that retained fetal bones should be considered in the differential diagnosis of women presenting to infertility clinics when there is a history of mid-trimester D&E of the uterus

Moxalactam Therapy for Obstetric and Gynecologic Infections

Moxalactam, a new cephalosporin antibiotic with a broad spectrum of activity, was evaluated for safety and therapeutic efficacy in the treatment of genital tract infections in women. Fifty-three patients with postpartum endometritis or acute or chronic pelvic inflammatory disease were treated with 2 g of moxalactam iv every 8 hr, usually for five days or longer. Appropriate cultures of peripheral blood, endometrium, cul-de-sac aspirates, urine, wound, and endocervix (only for Neisseria gonorrhoeae) were performed. Overall, 90.6% (48 of 53) of the patients were successfully treated with moxalactam - 86.2% (25 of 29) and 95.8% (23 of 24) of the patients with endometritis and pelvic inflammatory disease, respectively. Therapy failed in one of five bacteremic patients with endometritis. Of all the bacteria isolated from appropriate culture sites, 58% (224 of 383) were anaerobes, with anaerobic gram-negative rods - particularly Bacteroides bivius-and gram-positive cocci being predominant. Of 206 anaerobic strains tested with moxalactam by agar dilution techniques, 82% (169 of 206) were susceptible (minimal inhibitory concentration [MIC], ⩽8 μg/ml), 11.6% (24 of 206) were moderately susceptible (MIC, 16-32 μg/ml), and 6.3% (13 of 206) were resistant (MIC, ⩾64 μg/ml). Among the aerobic isolates, enterococci were uniformly resistant. Thus, moxalactam performed well as a single agent in this open clinical trail for women with infections of the genital trac

Wage effects of works councils and opening clauses: the German case

"German employment relations are characterized by a distinct dual system. First, working conditions and wages are determined by industry-level collective bargaining agreements. Second, on the establishment-level, the works council is responsible for employer - employee negotiations. However, since the mid-1980s, an increasing number of areas of regulation have been transferred from the industry- to the establishment-level using so-called opening clauses. The analysis in this article relies on rich German establishment data and reveals new insights into the institutional machinery of wage bargaining. While the existence of such clauses is related to higher wages, their application results in wage cuts of roughly the same size. The results also suggest that works councils, on average, are able to prevent the negative wage effects of opening clauses." (Author's abstract, IAB-Doku) ((en)

Unilateral visual loss resulting from orbital encroachment of an ethmoidal juvenile trabecular ossifying fibroma

Ossifying fibromas are mainly found in the mandible and maxilla. Reports of them arising in the ethmoid sinuses and orbits are rare. We present a case of an otherwise healthy 20-year-old man with gradual onset of right visual disturbance signified by right relative afferent pupillary defect due to a large unilateral ossifying fibroma arising from the ethmoid sinus compressing the medial half of the right orbit. We emphasise the multidisciplinary combined endoscopic endonasal and external approach to ensure a successful debulking of the fibroma
