The Egyptian Vulture Neophron percnopterus was once an abundant species in the Cabo Verde Islands. Since the 1960s though, and especially during the 1980–1990s, it consistently declined to near extinction. Evidence collected indicates a remnant population of about a dozen pairs or less, scattered through the desert rangelands of only three islands. Extensive enquiry work revealed that this likely resulted from the concomitant effects of the rise in unnatural mortality due to the formerly widespread and long-lasting use of dangerous pesticides and the (still on-going) poisoning of stray dogs and other nuisance animals, and a decrease in food resources associated with factors linked with development, such as urbanisation, rural abandonment and better sanitation. Avoiding imminent extinction calls for emergency action against current threats to the remaining vultures, such as poisoning and electrocution, but also potential causes of impaired fecundity such as hazardous pesticides and shortage of food resources.

Earlier activities on health technology assessment (HTA) started in Spain around 1984, with the creation of a National Advisory Board on HTA, and the development of national and regional HTA organizations in the early 1990s. In 2012, the Spanish Health Ministry established the Spanish Network for Health Technology Assessment of the National Health System (RedETS); funded at national level and including all public HTA organizations at national and regional levels. RedETSis focused on the assessment of nondrug health technologies to inform the revision (approval and funding or disinvestment) of the Benefit Portfolio of the Spanish NHS. In parallel with European Network for Health Technology Assessment (EUnetHTA), RedETS has been setting-up and sharing common procedures and methodological guidelines to ensure effective cooperation and mutual recognition of the scientific and technical production in HTA. The output of RedETS is fifty to sixty annual reports, including the production of full HTA reports, Clinical Practice Guidelines, methodological guidance reports, relative effectiveness assessments, tools to support shared decision making between patients and healthcare professionals, and monitoring studies. The HTA assessments requested by the Regional Health Authorities are the biggest component of the annual RedETS working plan. These assessment needs are identified according to a yearly process and prioritized by a Commission composed of representatives from all Spanish regions with the aid of the PRITEC tool. The objectives of this study are to report and update the normative and organizational state of HTA in Spain; describing noteworthy advances witnessed over the past 10 years, as well as discussing existing challenges.

Masked revelry, the quaffing of large amounts of wine and the sound of flutes … this cavalcade would pass through the streets of Rome every 13th June, even crossing the forum itself. As we will show later on, a connection can be established between this celebration (the Quinquatrus minusculae) and the statue of Marsyas, the acolyte of Dionysus, which stood in the forum and was associated with freedom, wine and charivari. In turn, this connection will open the way for a new interpretation of the multiple meanings of the feast and the satyr in the highly charged political atmosphere of Late Republican Rome. The main aim of this study will be to show, in the third part of this article, how populares politicians tried to exploit the opportunities presented to them by religious festivities and ludi to draw more of the public into their contiones or to obtain a favourable verdict in a political trial.

The rapid spread of glyphosate-resistant sourgrass populations generates concern in the agricultural production sector in Brazil. Nonetheless, there is not much information related to the frequency and dispersion of sourgrass throughout recent years. We investigated the frequency and dispersion of glyphosate-resistant sourgrass populations in Brazilian agricultural regions as part of a larger-scale weed resistance monitoring study. A discriminatory rate of 960 g ae ha−1 of glyphosate was used on plants at the 2- to 3-tiller stage, originating from 2,593 populations of sourgrass sampled in 329 counties in 14 Brazilian states between 2012 and 2015. The dispersion of sourgrass populations originated in western Paraná State, next to the Paraguay border, where the first resistance case was reported. Its dispersion to the central region of Brazil, mainly in soybean-producing areas, is most likely a consequence of agricultural equipment movement and wind-mediated dispersal. Glyphosate-resistant sourgrass populations were found in every geographical region across all Brazilian states tested. These data highlight the importance of an appropriate weed resistance monitoring program to track the evolution and dispersion of resistance to mitigate these issues by focusing efforts regionally and raising awareness among stakeholders in each region.

Chronic obstructive pulmonary disease (COPD) is one of the most important and prevalent diseases suffered by the elderly. Evidence exists that its onset and severity might be conditioned by antioxidant status. The aim of the present study was to investigate the relationship between antioxidant status and COPD in institutionalised elderly people. In all, 183 elderly people aged >65 years (twenty-one had COPD and 160 healthy controls) were studied. The subjects’ diets were investigated via the use of precise individual weighing for 7 d. Body weight, height, and biceps and triceps skinfold thickness were measured, and body fat (kg) and BMI (kg/m2) were calculated. Serum retinol, α-tocopherol, β-carotene and vitamin C levels were determined. Subjects with COPD ate less fruits than healthy controls (117 (sd 52) v. 192 (sd 161) g/d), their coverage of the recommended intake of vitamin C was smaller (150 (sd 45) v. 191 (sd 88) %; note that both exceeded 100 %) and their diets had a lower antioxidant capacity (6558 (sd 2381) v. 9328 (sd 5367) mmol trolox equivalent/d). Those with COPD had lower serum vitamin C and α-tocopherol concentrations than healthy controls (32·4 (sd 15·3) v. 41·5 (sd 14·8) µmol/l and 12·1 (sd 3·2) v. 13·9 (sd 2·8) µmol/l, respectively). In addition, subjects with α-tocopherol <14·1µmol/l (50th percentile) were at 6·43 times greater risk of having COPD than those subjects with ≥14·1µmol/l (OR 6·43; 95 % CI 1·17, 35·24; P<0·05), taking sex, age, use of tobacco, body fat and vitamin E intake as covariables. Subjects with COPD had diets of poorer antioxidant quality, especially with respect to vitamins C and E, compared with healthy controls.

In species that aggregate for reproduction, the social and fitness costs of movement between groups frequently lead to restricted exchange between breeding areas. We report on four individual humpback whales identified in both the Cape Verde Islands and Guadeloupe; locations separated by an ocean basin and >4000 km. This rate of exchange is rarely encountered between such geographically discrete breeding areas. Two individuals returned to the area where they were originally identified. In contrast, no individuals from the Cape Verde Islands were resighted to the much larger sample from the Dominican Republic, though the migratory distances from the feeding areas are comparable between these areas. The social factors driving the stark difference between groups that is observed here are not clear. Effective conservation requires an understanding of the extent and pattern of movement between population units. The findings presented here suggest that there may well be more than one behaviourally distinct group within the West Indies. More broadly, they argue that considerable caution is warranted in assumptions made regarding the number, boundaries and status of population units based solely on spatial separation or proximity.

Anthropometric reference data for older adults, particularly for the oldest old, are still limited, especially in developing countries. The aim of the present study was to describe sex- and age-specific distributions of anthropometric measurements and body composition in Mexican older adults. The methods included in the present study were assessment of height, weight, BMI, calf circumference (CC), waist circumference (WC) and hip circumference (HC) as well as knee height in a sample of 8883 Mexican adults aged 60 years and above and the estimation of sex- and age-specific differences in these measures. Results of the study (n 7865, 54 % women) showed that men are taller, have higher BMI, and larger WC than women, whereas women presented higher prevalence of obesity and adiposity. Overall prevalence of underweight was 2·3 % in men and 4·0 % in women, with increasing prevalence with advancing age. Significant differences were found by age group for weight, height, WC, HC, CC, BMI and knee height (P<0·001), but no significant differences in waist–hip circumference were observed. Significant differences between men and women were found in height, weight, circumferences, BMI and knee height (P<0·001). These results, which are consistent with studies of older adults in other countries, can be used for comparison with other Mexican samples including populations living in the USA and other countries with similar developmental and socio-economic conditions. This information can also be used as reference in clinical settings as a tool for detection of individuals at risk of either underweight or overweight and obesity.

It was established that at selective laser sintering of Al2O3 - Al compacted mixtures oxidation of the Al particles took place due to diffusion of oxygen into the volume of the workpieces. Depending on the content of aluminum, composite ceramics of various types were formed.

The non-ferrous shape memory alloys have, normally, two problems that hinder its use in industrial scale: the natural aging and grains growth. The first degrades the memory effect, while the second, observed during the processing of alloy, modifies the temperatures which the transformations occur. Thus, the study of kynetic of recrystallization is important for enabling the control of hardened state in function of treatment time, without causing excessive grain growth. Therefore, the objective of this study is to determine the kinetics of recrystallization of Cu-14Al-4Ni shape memory alloy, based on an empirical law of the formation of Jonhson-Mehl-Avrami, as well as their activation energies for grain growth process according to the empirical Arrhenius law. The alloy was vacuum melted in an induction furnace. After casting, the bulk samples of the alloy were homogenized for 24 hours, solubilized and hot rolled followed by water-quenching to initiate the recrystallization. Then, different samples were annealed at temperatures close to the peak, start and end of the DSC curve. Following the heat treatments, the samples were submitted to mechanical tests and the values of the properties were correlated to the fraction transformed for determination of recrystallization’s kinetic. For the characterization of the grain growth process, analyses in optical microscopy were accomplished and all annealed samples were examined by statistical metallography and the grain sizes were measured. After measurements, the ln[-ln(1-Y rec )] x ln(t) and the ln [D-D o ] x 1/T diagrams were plotted to determine the parameters of Jonhson-Mehl-Avrami equation and the activation energy of the process, respectively. The results showed that the equation of the recrystallized fraction follows the empiric law of the formation of Jonhson-Mehl-Avrami for the considered property, as well as, also showed that the alloy Cu-14Al-4Ni is extremely sensitive to temperature variation in which the alloy is treated, having a dual kinetics of grain growth. In the first domain, between 670 and 710°C, the diagram provides a value for the activation energy equal to 39.32 KJ/mol, in the second domain, between 710 and 790°C, the diagram provides a value for the activation energy equal to 9.01 KJ/mol.

The effects of thermal treatments on the thermoluminescent (TL) signal of NaCl (ACS reagent) induced by gamma radiation were investigated. Samples of NaCl were thermally treated at 500, 800 and 1000 °C and characterized by X-Ray diffraction and scanning electron microscopy. After their exposure 0.1 to 150 Gy of gamma radiation from a gamma-ray source of 60Co, a TL curve for each temperature of treatment was obtained. We observed a different TL behavior on the irradiated samples as a function of the temperature applied during the thermal treatments. For the sample treated at 500 °C, three peaks centered at 102, 133 and 228 °C were observed. Samples treated at 800 and 1000 °C showed two main peaks at 128 and 220 °C and 136 and 219 °C, respectively; however, the highest TL intensity signal was observed for the sample at 800 °C. All samples showed a linear dependency of the integrated TL intensity from the signal emitted as function of the irradiation time. This is an important advantage because NaCl could be applied as a very low cost thermoluminescent dosimetric material. A comparison between the TL signal induced by gamma radiation in pure and Eu doped NaCl is also reported.

In this work, the annealing effects at 180°C in Aluminum-ZnO contacts as function of time were studied. Also, the application in TFTs of ZnO films obtained at low-temperature (200°C) are presented. The ZnO films obtained by ultrasonic Spray Pyrolysis at 200 °C were deposited over Aluminum contacts on SiO2/Si wafers to demonstrate the use of active layer in thin-film transistors. The results show that an improvement can be obtained in metal-ZnO interfaces by low-temperature annealing treatments. However, long annealing time degrade the metal-ZnO interface and may affect the electrical performance of the device.

The objective of this study was to determine whether a generic diet could be developed for three species of Anastrepha: A. ludens, A. obliqua and A.serpentina. Laboratory and mass-rearing tests to assess the suitability of the A. ludens (Loew) (ALU) diet, normally used for rearing A. ludens, indicated that it was also suitable for rearing A. obliqua (Macquart) and A. serpentina (Wiedemann). Therefore, this diet appeared to be a suitable generic diet for the three species based on quality control parameters. In comparison with those observed when rearing larvae on the commonly used A. obliqua diet, the number of A. obliqua larvae recovered per g diet increased from 4.2 to 5.1, larval weight increased from 17 to 18.2 mg, pupation after 24 h from 89.3 to 96.9%, adult emergence from 91.5 to 93.7% and flight ability (% of fliers) from 86.1 to 90.4% when reared on the ALU diet. Usually, A. serpentina larvae are reared on the A. serpentina diet, but when reared on the ALU diet, larval recovery increased from 61.8 to 69.8%, number of larvae recovered per g diet from 3.7 to 4.4, larval weight from 21.7 to 23.8 mg and flight ability from 64.6 to 70.2%. These results show that the nutritional requirements of the three Anastrepha species are similar. The use of a generic diet for rearing the three species requires only one line to prepare the diet, reducing time and labour costs.

We present the optical/infrared counterpart to GT0106+613, a transient gamma-ray source believed to be a blazar. Long-term differential photometry and satellite information was used to confirm the variability in optical/infrared wavelengths, correlated with gamma-ray flares from the source. An intense optical flare with no counterpart in gamma-rays is also remarkable.

Efficient charge transport is key to the operation of the various devices based on organic semiconductors, such as OLEDs, OPVs and OFETs. Both academia and industry are investing heavily in the development of new organic materials and processing techniques to improve device performance. An important parameter to tweak is the mobility of charge carriers. Triggered by an experimental result, here we investigate whether this parameter can be probed indirectly using UV-VIS spectroscopy. This would simplify the process of characterization and optimization of the mobility in amorphous molecular films, for example.

Immature oocytes synthesize a variety of proteins that include the enzyme glucose-6-phosphate dehydrogenase (G6PDH). Brilliant cresyl blue (BCB) is a vital blue dye that assesses intracellular activity of G6PDH, an indirect measure of oocyte maturation. The objective was to evaluate the BCB test as a criterion to assess developmental competence of equine oocytes and to determine if equine growth hormone (eGH) enhanced in vitro maturation (IVM) of equine oocyte. Cumulus–oocytes complexes (COCs) were recovered by aspirating follicles <30 mm in diameter from abattoir-derived ovaries and were evaluated morphologically. Thereafter, COCs were exposed to BCB (26 μM) for 90 min at 39°C and selected based on the colour of their cytoplasm (BCB positive/BCB+ or BCB negative/BCB–). The COCs were allocated as follows: (a) IVM medium; (b) eGH group; (c) BCB–/IVM; (d) BCB+/IVM; (e) BCB–/eGH; and (f) BCB+/eGH. Then, COCs were cultured in vitro for 30 h, at 39°C in a 5%CO2 humidified air atmosphere. Cumulus-free oocytes were incubated in 10 μg/ml of bis-benzamide for 20 min at 39°C and nuclear maturation was evaluated with epifluorescence microscopy. Of the 39 COCs selected morphologically and subjected to BCB staining, 18/39 (46.2%) were classified as BCB+ and 21/39 (53.8%) as BCB– (P > 0.05). Maturation was not affected significantly by BCB classification, but the maturation rate was higher for oocytes that had been exposed to exogenous eGH versus controls (16/28, 57.1% versus 8/26, 30.8%, P < 0.05). In the present study, the BCB test was not useful for predicting competent equine oocytes prior to IVM. However, eGH enhanced equine oocyte maturation in vitro.
