In an observational study in men with erectile dysfunction (ED) consulting a general practitioner (GP) or urologist in Belgium, demographics, ED characteristics (including erection hardness score), co-morbidities and treatment expectations were evaluated using a structured questionnaire. In total, 341 GPs and 41 urologists recruited 1492 patients. Most (74%) were untreated and 25% had ED for >3 years. Considering PDE5 inhibitors, erection hardness (89%) and maintenance (92%) were considered 'very important' by most patients. Only 18% of physicians initiated discussion about ED, despite 41% of patients having >or=3 known risk factors. The questionnaire was considered helpful by 81% of GPs and 83% of their patients. Overall, patients are under-diagnosed, and physicians are reluctant to ask about ED. A questionnaire including erection hardness score is useful to facilitate discussion about ED in general practice. Erection hardness and maintenance are more important to patients as compared to fast onset or long duration of action. [less ▲]

This presentation is dedicated to real time hybrid testing of building members subjected to the action of fire. It will be shown why, whereas pseudo-dynamic testing is possible in other fields, real time hybrid testing is the only possible option for the evaluation of fire performance (except, perhaps, for pure metallic unprotected structures). For some structures subjected to fire, the load bearing mechanism in the physical component is completely modified during the test and this modification can take place within a very short period of time. Because of that, the computational demand can be very challenging if the simulated element is simulated in a fully nonlinear computer model, especially if the thermal problem (temperature distribution in the structure) and the mechanical problem have both to be solved within each time step. In order to avoid these difficulties, a possible solution may be to calculate the stiffness matrix that dictates the reaction of the simulated element on the tested element before the test. This matrix can be constant or vary as a function of the displacements measured at the interface during the test. This procedure is very robust but it also has some shortcomings and limitations. The main topic of this paper is the discussion of the advantages and limitations of this procedure applied to hybrid fire testing. A series of three tests which is now under preparation to be performed in the furnace PROMETHEE of CERIB, in France, will also be described in this respect. Preliminary results will be presented if some or all of the tests have been performed at the date of the conference. [less ▲]

Strong increase in demand for animal products could benefit local producers in developing countries. This development opportunity particularly concerns suburban livestock. In Burkina Faso, the suburban area of Ouagadougou is a place for the setting up of an increasing number of breeders. Due to its importance in religious traditions, spurring its consumption in whole West Africa, mutton is a major part of this suburban production. In order to characterize sheep farming in the suburban zone of Ouagadougou, in terms of motives, practices, and economic performance, and to better understand the dynamic at play in the sheep sector, a survey has been conducted among 80 sheep farmers around Ouagadougou. The results show that suburban sheep keeping is a highly dual sector. Nearly half (42.5 %) of farms may be described as traditional livestock, while 50% are evolving towards intensification. These two groups essentially differ in terms of animal genetic and feeding management, farm infrastructure, and farmer education level. Economically, the whole sample tends to indicate a lack of profitability of the activity in terms of monetary income. Several factors contributing to this situation are pinpointed, namely feed and animal health constraints, flock and production management, and the market conditions. [less ▲]

To define the independent variables predictive of early versus late mortality after acute myocardial infarction (AMI), 420 consecutive patients were studied and divided into 3 groups: the 45 patients who died within the initial 3 months (group 1), the 45 patients who died greater than 3 months and less than or equal to 3 years after AMI (group 2) and the 330 greater than 3-year survivors (group 3). The stepwise logistic discrimination method was applied to clinical and laboratory variables recorded during hospitalization to distinguish among the 3 groups. Six independent variables were found to be predictive of early mortality: left ventricular function score (chi-square 26.2; p less than 0.00001), ventricular fibrillation (chi-square 9.3; p = 0.002), bundle branch block (chi-square 9.0; p = 0.003), history of previous AMI (chi-square 8.7; p = 0.003), age (chi-square 5.8; p = 0.02) and atrioventricular block (chi-square 3.8; p = 0.05). Three independent variables were found predictive of late mortality: age (chi-square 13.8; p = 0.0002), anterior location of the AMI (chi-square 4.0; p = 0.04) and a low peak creatine kinase-MB level (chi-square 3.8; p = 0.05). Only 2 variables were able to distinguish between early and late nonsurvivors: peak creatine kinase-MB level (chi-square 8.7; p = 0.003) and ventricular fibrillation (chi-square 4.6; p = 0.03). Thus, the sets of independent risk factors for early and late mortality after AMI are substantially different--suggesting that differing mechanisms are responsible for outcome. [less ▲]

This study evaluates the actions taken by obese adolescents in an attempt to lose weight in relation to changes in weight. Particular emphasis is put on the context surrounding the management process. Thirty one obese adolescents aged 14-18 participated in this study. The adolescents answered a written questionnaire, took a body-size dissatisfaction test and were interviewed. Their family physicians were interviewed by telephone. Quantitative data concerned changes in weight and body-size dissatisfaction scores. Qualitative analysis included cases analyses and building up of synthesis variables. Loss of weight is linked with continuity of management attempts as well as with medical follow-up. The most frequent management attempt is diet. Self-image is correlated with weight. The exclusive emphasis put on diet is discussed in relation to the importance of more psychosocial factors such as self-image, denial and attraction to discontinuity. Some recommendations for the management of overweight adolescents are then outlined. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved. [less ▲]

Traditional sorghum beers are produced in several countries of Africa, but variations in the manufacturing process may occur depending on the geographic localization. These beers are very rich in calories, B-group vitamins including thiamine, folic acid, riboflavin and nicotinic acid, and essential amino acids such as lysine. However, the traditional sorghum beer is less attractive than Western beers because of its poorer hygienic quality, organoleptic variations and shorter shelf life. Research into the microbiological and biochemical characteristics of traditional sorghum beers as well as their technologies have been performed and documented in several African countries. This review aims to summarize the production processes and compositional characteristics of African traditional sorghum beers (ikigage, merissa, doro, dolo, pito, amgba and tchoukoutou). It also highlights the major differences between these traditional beers and barley malt beer, consumed worldwide, and suggests adaptations that could be made to improve the production process of traditional sorghum beer.

The current study aims to assess the breeding system, the herd structure of the cattle farm and the climate changes in the municipality of Banikoara. It appears that the majority of farmers was from Fulani ethnic group, of 46 years old and married. Livestock farming was their main activity. The main crops produced included maize, sorghum, millet and cotton. The reared animal species were composed of cattle, goats, sheep, pigs, chickens and guinea fowl with the predominance of chicken (p <0.05) . The exploited cattle breeds were Borgou, Somba Zebu Peulh, Barougoudji, Bororo, Kiwali and Kétégui with a predominance of the cattle Borgou (p <0.001). The cattle breeding systems were of traditional type. The reported age at first calving varies between 2.5 and 4 years. The calving interval fluctuates between 8 and 13 months. The best daily milk production per cow was reported in the district of 5 (8.38 liters) and lowest yields was obtained in districts 1 (p <0.05). The longevity of the animals varied between 8 and 14 years. The selection criteria used in the choice of reproductive cattle by farmers were the coat color, format, health, size of limb and conformation of limbs. The climate change manifestations in the municipality of Banikoara were reported as frequent droughts, high winds, excessive heat, scarceness of rains and frequent floods, declines of pastoral productivity, overgrazing, reduction of water resources and crop residues and shrinking corridors.

In Vietnam, the economic growth in recent years has brought a strong demand for animal products consumption, particularly poultry meat. This research aims to better understand how the factors in the duck sector adapt to current economic conditions in Red River Delta and Mekong Delta by analyzing livestock farming systems with their various constraints. The research had been conducted by interviewing and production record keeping system at the household farms which have duck production at different scales in Hanoi Suburbs in Red River Delta from December 2008 to November 2009 and Long An Province in Mekong Delta from March to August, 2007. Three duck production systems have been identified (1) industrial duck production system with high-yield potential imported races; (2) transhumant duck production system at semi-industrial scale with local or cross-bred ducks. Broiler or layer ducks are freely grazed or transhumant on rice fields for taking the residual paddy; and (3) duck production system at small scale or backyard production. Broiler duck farms have obtained weak productivity with high mortality rate. The net income has varied from 7,358,000 to 10,151,000 Vietnam Dongs per farm per year with broiler ducks and reproductive ducks at semi-industrial and industrial systems. Backyard duck farms are widely practiced in household farms with low investment. The net income of duck production is also weak in households (728,000 Vietnam Dongs per farm per year with broiler ducks and 1,368,000 Vietnam Dongs with layer ducks. Majority surveyed farms raised various species of chickens and ducks. Duck meat production also aims to satisfy a significant share of the demand for self-consumption with ducks in small households.

The familial occurrence of pituitary adenomas has been recognized for many years and currently accounts for approximately 5% of all cases. Molecular, genetic and clinical features of familial pituitary adenomas have been well characterized in multiple endocrine neoplasia type 1 (MEN-1) and Carney's complex (CNC), which account for the majority of familial pituitary tumor cases. These conditions are caused by MEN1 and PRKAR1A gene mutations, respectively, and the clinical and pathological features of pituitary pathology in these diseases differ from those of sporadic pituitary tumors. Familial acromegaly has been recognized for many years and, more recently, the clinical features of this clinical phenotype, referred to as isolated familial somatotropinoma, have been clarified. Over the past decade, the concept of non-MEN-1/CNC familial pituitary tumors has been expanded significantly to include all phenotypes, a condition known as familial isolated pituitary adenomas (FIPA). In FIPA, tumors can present homogeneously (same phenotype) or heterogeneously (different tumor phenotypes) within the same family. Compared with sporadic pituitary adenomas, patients with FIPA have a younger age at diagnosis and have larger tumors. The clinical features of FIPA differ from those of MEN-1 in terms of a higher frequency of somatotropinomas and a lower frequency of prolactinomas. The recent discovery of the involvement of mutations in the aryl hydrocarbon receptor interacting protein (AIP) gene in association with pituitary tumors has provided new information regarding potential mechanisms of tumorigenesis in FIPA patients. While very infrequent in sporadic pituitary tumors, approximately 15% of FIPA patients have AIP mutations, rising to half of patients with familial acromegaly. In this review, we detail the clinical features of FIPA and discuss tumor pathology and genetic findings in this increasingly recognized clinical condition. [less ▲]

Observation of an exceptionally bright (peaking at similar to 1.8 MR) Jovian auroral morning arc was obtained with the Space Telescope Imaging Spectrograph (STIS) on 21 September 1999, both in the imaging and spectral modes. The images of the HST orbit are used to describe the variation of the position of the bright arc, while the time-tagged spectra are examined to derive the properties of the precipitating auroral electrons, such as their mean energy and the electron current density at the top of the atmosphere. The first and the last images of the HST orbit, separated by 37 min, show that the bright morning emission is situated on the reference oval, with a "leading" edge fixed in lambda(III) longitudes (i.e., rotating with the planet), and a "trailing" edge that extends into the nightside. The auroral arc is divided in two branches, as was also observed in some previous analyses. An isolated bright spot is also observed at lambda(III) similar to 184 degrees. Its brightness reaches 500 kR and it also approximately corotates with Jupiter. Four regions of the auroral morning arc captured by the STIS aperture were extracted from the spectral observation. The four associated low-resolution spectra (similar to 4.8 degrees) show very different characteristics. In particular, two spectra reveal unusually high color ratios (18.5 and 45.5), with corresponding mean electron energies of similar to 280 and similar to 460 keV, respectively. The current densities associated with three of the spectra lie in the range 0.09-0.2 mu A m(-2), consistent with previous estimates, while the fourth spectrum is characterized by a mean current density of 0.54 mu A m(-2), outside the range similar to 0.04-0.4 mu A m(-2) obtained in a previous study of G140L spectra of the Jovian main oval. Assuming that main oval aurorae are caused by field-aligned electric fields, the relationship between the energy flux and the current density derived from the spectra has been compared to the Knight's theory of field-aligned currents. Because of the very high acceleration potential derived from two of the extracted spectra, a relativistic treatment of the Knight theory was used. Assuming an electron temperature T-e = 2.5 keV, it is seen that the two regions corresponding to earlier local times (higher lambda(III) longitudes) reveal an electron source density lower than the values observed in the equatorial plane during the Voyager flybys. On the other hand, the equatorward region (lowest latitude) exhibits an electron source density in the upper range of usual values. Analysis of time-tag spectra reveals that the variations of the energy flux and the color ratios are large but continuous and generally covary. [less ▲]

Jupiter’s dynamic auroral region is the signature of magnetosphere-ionosphere coupling. The magnetospheric drivers of the emission are relatively well understood, yet the high-latitude characteristics of the interaction have not been measure in-situ. Ahead of Juno’s arrival next summer, we use HST STIS observations of Jupiter’s auroral emission to infer the location of Jupiter’s auroral acceleration region and the properties of the precipitating auroral electrons. We analyze two images of Jupiter’s northern emission, determining the precipitating electron energy and incident energy flux for the main aurora, Io spot, Ganymede footprint, and flare regions. The resulting relationships between energy flux and electron precipitation energy for the main auroral emission are compared to the theoretical relationship derived by Lundin & Sandahl [1978] for a range of auroral region locations, and temperatures and densities appropriate for the jovian system.
