The effect of latent heat release on synoptic-to-planetary scale wave interactions: Observational study
A blocking pattern which formed over eastern North America following the landfall of Hurricane Juan during November 1985 was investigated. It is hypothesize that latent heat released in the Hurricane's rainfall was either directly or indirectly responsible for the large observed 500 mb height rises over eastern Canada during the formation of this block. This idea is evaluated with a diagnostic model for the height tendency field which includes latent heat release as a forcing function. The total column heating is calculated using satellite-derived precipitation estimates. These estimates are qualitatively congruent with observations, but overestimate light rainfall and underestimate heavy rainfall. The calculations reveal that the direct contribution of the heating to the 500 mb height tendency field is small relative to the quasigeostrophic forcing. However, maxima in heating coincide with regions where anticyclonic potential vorticity is generated. Once such region is just upstream of the location of large 500 mb height rises in the incipient block. An indirect role is proposed for the heating in this case. Specifically, anticyclonic potential vorticity is generated near the heating maxima; this vorticity is then advected downstream, forcing the 500 mb heights to rise and the block to develop

Quality of life in workers and stress: gender differences in exposure to psychosocial risks and perceived well-being
Background. Quality of working life is the result of many factors inherent in the workplace environment, especially in terms of
exposure to psychosocial risks. Objectives. The purpose of this study is to assess the quality of life with special attention to gender
differences. Methods. The HSE-IT questionnaire and the WHO-5 Well-Being Index were administered to a group of workers (74
males and 33 females). The authors also used Cronbachâs alpha test to assess the internal consistency of both questionnaires and the
MannâWhitney test to evaluate the significance of gender differences in both questionnaires. Results. The HSE-IT highlighted the
existence of work-related stress in all the population with a critical perception regarding the domain âRelationships.â Furthermore,
gender analysis highlighted the presence of two additional domains in the female population: âDemandâ ( = 0,002) and âSupport
from Managersâ ( = 0,287). The WHO-5 highlighted a well-being level below the standard cut-off point with a significant gender
difference ( = 0.009) for males (18, SD = 6) as compared to females (14, SD = 6,4). Cronbachâs alpha values indicated a high level of
internal consistency for both of our scales. Conclusions. The risk assessment of quality of working life should take into due account
the individual characteristics of workers, with special attention to gender
The endocannabinoid system in migraine: from bench to pharmacy and back.
PURPOSE OF REVIEW: Migraine is a common, highly disabling disorder. Its treatment involves acute and preventive therapy. Many of available preventive medications are not well tolerated, which results in poor compliance and limited effectiveness. Cannabinoids have been proposed for the treatment of migraine but their efficacy and tolerability are controversial.
RECENT FINDINGS: Cannabinoids modulate functions and activity of signaling pathways that have a key role in pain control. Growing preclinical evidence and initial clinical findings suggest that modulation of the endocannabinoid system, via endogenous or exogenous cannabinoids may be relevant for migraine via multiple mechanisms.
SUMMARY: The endocannabinoid system qualifies as an interesting area of research worth exploration in the quest for therapeutic targets for the treatment of migraine

A rare case of an aldosterone secreting metastatic adrenocortical carcinoma and papillary thyroid carcinoma in a 31-year-old male
We report a rare synchronous presentation of adrenocortical carcinoma (ACC) and papillary thyroid carcinoma (PTC). A 31-year-old male first presented with a large left adrenal mass that was identified during the workup for refractory hypertension due to hyperaldosteronism. The mass was removed surgically with pathology showing ACC. The patient was then treated with adjuvant radiation therapy and mitotane chemotherapy. Four months post ACC resection, metastatic ACC to the right upper lung and PTC in the left lobe of the thyroid were found in surveillance imaging. He subsequently developed pulmonary, contralateral adrenal and brain metastases from his ACC. Li Fraumeni syndrome and Multiple Endocrine Neoplasia Type I (MEN I) were considered, but testing of both P53 and menin genes showed no mutation. We also performed a review of the literature and found three similar cases, however gene mutation analysis was not performed.
All-sky search for long-duration gravitational wave transients with initial LIGO
We present the results of a search for long-duration gravitational wave transients in two sets of data collected by the LIGO Hanford and LIGO Livingston detectors between November 5, 2005 and September 30, 2007, and July 7, 2009 and October 20, 2010, with a total observational time of 283.0 days and 132.9 days, respectively. The search targets gravitational wave transients of duration 10â500 s in a frequency band of 40â1000 Hz, with minimal assumptions about the signal waveform, polarization, source direction, or time of occurrence. All candidate triggers were consistent with the expected background; as a result we set 90% confidence upper limits on the rate of long-duration gravitational wave transients for different types of gravitational wave signals. For signals from black hole accretion disk instabilities, we set upper limits on the source rate density between 3.4Ă10â5 and 9.4Ă10â4ââMpcâ3âyrâ1 at 90% confidence. These are the first results from an all-sky search for unmodeled long-duration transient gravitational wave
Search of the Orion spur for continuous gravitational waves using a loosely coherent algorithm on data from LIGO interferometers
We report results of a wideband search for periodic gravitational waves from isolated neutron stars within the Orion spur towards both the inner and outer regions of our Galaxy. As gravitational waves interact very weakly with matter, the search is unimpeded by dust and concentrations of stars. One search disk (A) is 6.87° in diameter and centered on 20h10m54.71s+33°33â˛25.29â˛â˛, and the other (B) is 7.45° in diameter and centered on 8h35m20.61sâ46°49â˛25.151â˛â˛. We explored the frequency range of 50â1500 Hz and frequency derivative from 0 to â5Ă10â9ââHz/s. A multistage, loosely coherent search program allowed probing more deeply than before in these two regions, while increasing coherence length with every stage. Rigorous follow-up parameters have winnowed the initial coincidence set to only 70 candidates, to be examined manually. None of those 70 candidates proved to be consistent with an isolated gravitational-wave emitter, and 95% confidence level upper limits were placed on continuous-wave strain amplitudes. Near 169 Hz we achieve our lowest 95% C.L. upper limit on the worst-case linearly polarized strain amplitude h0 of 6.3Ă10â25, while at the high end of our frequency range we achieve a worst-case upper limit of 3.4Ă10â24 for all polarizations and sky location
Monetary and fiscal policies for a finite planet
Current macroeconomic policy promotes continuous economic growth. Unemployment, poverty and debt are associated with insufficient growth. Economic activity depends upon the transformation of natural materials, ultimately returning to the environment as waste. Current levels of economic throughput exceed the planet\u27s carrying capacity. As a result of poorly constructed economic institutions, society faces the unacceptable choice between ecological catastrophe and human misery. A transition to a steady-state economy is required, characterized by a rate of throughput compatible with planetary boundaries. This paper contributes to the development of a steady-state economy by addressing US monetary and fiscal policies. A steady-state monetary policy would support counter-cyclical, debt-free vertical money creation through the public sector, in ways that contribute to sustainable well-being. The implication for a steady-state fiscal policy is that any lending or spending requires a careful balance of recovery of money, not as a means of revenue, but as an economic imperative to meet monetary policy goals. A steady-state fiscal policy would prioritize targeted public goods investments, taxation of ecological bads and economic rent and implementation of progressive tax structures. Institutional innovations are considered, including common asset trusts, to regulate throughput, and a public monetary trust, to strictly regulate money supply
