Qualidade de vida de pessoas com estomias intestinais

Ostomy is an open surgical origin, when it is necessary to deviate temporarily or permanently, the normal transit of food and / or deletions. The patient with ostomy disposal is faced with changes in their physiology, also emerging on the need to care collection bag. This study aimed to analyze the quality of life (QOL) of people living with ostomy Intestinal (EI), who attended the Pediatric and Adult Rehabilitation Center of Rio Grande do Norte (CRI / CRA-RN). It is an analytical study with cross-sectional design and quantitative approach, accomplished with 89 people who had EI. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (CEP / UFRN), CAAE: 19866413.3.0000.5537. Held data collection in the period January-March 2015 using two instruments: an adapted general questionnaire covering socio-demographic, clinical and self-care and a specific instrument for assessing QOL of people with stoma titled as City of Hope Quality of Life - Ostomy Questionnaire (COH-QOL-Q), validated and adapted to Portuguese in 2010, composed of four areas, namely: Welfare Body (BEF), Welfare Psychological (BEP), Welfare (BES ) and Spiritual Well-Being (BEE). The collected data were entered into a database in Microsoft Excel 2007 spreadsheet application and processed in computerized software for descriptive and inferential analysis. The results showed that 83.1% had a colostomy and ileostomy 16.9%. Sociodemographic characteristics prevailed in males (57.3%), over 50 (57.3%), mulatto (46.1%), with presence of companion / a (57.3%), retired / beneficiaries (50.5%), monthly income above the minimum wage (68.5%) and who have studied up to elementary school (67.4%). Regarding clinical aspects, it was observed that the main cause that led to the making of the stoma was the neoplasm (59.6%) followed by trauma (21.3%). The sample showed people with stoma for more than six months (79.8%) of permanently (57.3%), in use sink equipment piece drainable (68.5%) of flat base (82.0%). With respect to self-care, 93.3% emptied and washed the bag alone (care related to hygiene) and 75.3% fixed the new exchange on the skin during the exchange (care related to the stock). Patients with more than six months of ostomy and had no partner (a) had higher averages of self-care related hygiene and purse. The average of respondents QoL scores was 68.90% for General QOL; 68.03% for the BEF; 68.38% for the BEP; 66.46% for BES and 75.41% for BEE. Among the aspects that influenced QOL included: physical strength, pain, suffering and gases (physical domain); appearance, care of the stoma and adaptation to new condition (psychological domain); isolation, interference in personal relationships and social activities (social domain) and going to church or synagogue, spiritual activities and positive change after ostomy (spiritual realm). Based on these results, it is concluded that this was a predominantly adult sample / elderly (between 50 and 70 years), with low education and the cause motivating the stoma, neoplasms. However, such findings did not pass at low percentage levels on the self-care capacity to deliver even at low QOL scores.

Widespread exploitation of the honeybee by early Neolithic farmers

The pressures on honeybee (Apis mellifera) populations, resulting from threats by modern pesticides, parasites, predators and diseases, have raised awareness of the economic importance and critical role this insect plays in agricultural societies across the globe. However, the association of humans with A. mellifera predates post-industrial-revolution agriculture, as evidenced by the widespread presence of ancient Egyptian bee iconography dating to the Old Kingdom (approximately 2400 bc)1. There are also indications of Stone Age people harvesting bee products; for example, honey hunting is interpreted from rock art2 in a prehistoric Holocene context and a beeswax find in a pre-agriculturalist site3. However, when and where the regular association of A. mellifera with agriculturalists emerged is unknown4. One of the major products of A. mellifera is beeswax, which is composed of a complex suite of lipids including n-alkanes, n-alkanoic acids and fatty acyl wax esters. The composition is highly constant as it is determined genetically through the insect’s biochemistry. Thus, the chemical ‘fingerprint’ of beeswax provides a reliable basis for detecting this commodity in organic residues preserved at archaeological sites, which we now use to trace the exploitation by humans of A. mellifera temporally and spatially. Here we present secure identifications of beeswax in lipid residues preserved in pottery vessels of Neolithic Old World farmers. The geographical range of bee product exploitation is traced in Neolithic Europe, the Near East and North Africa, providing the palaeoecological range of honeybees during prehistory. Temporally, we demonstrate that bee products were exploited continuously, and probably extensively in some regions, at least from the seventh millennium cal bc, likely fulfilling a variety of technological and cultural functions. The close association of A. mellifera with Neolithic farming communities dates to the early onset of agriculture and may provide evidence for the beginnings of a domestication process.

Superinfection exclusion and the long-term survival of honey bees in Varroa-infested colonies

Over the past 50 years, many millions of European honey bee (Apis mellifera) colonies have died as the ectoparasitic mite, Varroa destructor, has spread around the world. Subsequent studies have indicated that the mite’s association with a group of RNA viral pathogens (Deformed Wing Virus, DWV) correlates with colony death. Here, we propose a phenomenon known as superinfection exclusion that provides an explanation of how certain A. mellifera populations have survived, despite Varroa infestation and high DWV loads. Next-generation sequencing has shown that a non-lethal DWV variant ‘type B’ has become established in these colonies and that the lethal ‘type A’ DWV variant fails to persist in the bee population. We propose that this novel stable host-pathogen relationship prevents the accumulation of lethal variants, suggesting that this interaction could be exploited for the development of an effective treatment that minimises colony losses in the future.

A novel hybrid swarm based approach for curriculum based course timetabling problem

This work applies a hybrid approach in solving the university curriculum-based course timetabling problem as presented as part of the 2nd International Timetabling Competition 2007 (ITC2007). The core of the hybrid approach is based on an artificial bee colony algorithm. Past methods have applied artificial bee colony algorithms to university timetabling problems with high degrees of success. Nevertheless, there exist inefficiencies in the associated search abilities in term of exploration and exploitation. To improve the search abilities, this work introduces a hybrid approach entitled nelder-mead great deluge artificial bee colony algorithm (NMGD-ABC) where it combined additional positive elements of particle swarm optimization and great deluge algorithm. In addition, nelder-mead local search is incorporated into the great deluge algorithm to further enhance the performance of the resulting method. The proposed method is tested on curriculum-based course timetabling as presented in the ITC2007. Experimental results reveal that the proposed method is capable of producing competitive results as compared with the other approaches described in literature

ENABLING HARDWARE TECHNOLOGIES FOR AUTONOMY IN TINY ROBOTS: CONTROL, INTEGRATION, ACTUATION

The last two decades have seen many exciting examples of tiny robots from a few cm3 to less than one cm3. Although individually limited, a large group of these robots has the potential to work cooperatively and accomplish complex tasks. Two examples from nature that exhibit this type of cooperation are ant and bee colonies. They have the potential to assist in applications like search and rescue, military scouting, infrastructure and equipment monitoring, nano-manufacture, and possibly medicine. Most of these applications require the high level of autonomy that has been demonstrated by large robotic platforms, such as the iRobot and Honda ASIMO. However, when robot size shrinks down, current approaches to achieve the necessary functions are no longer valid. This work focused on challenges associated with the electronics and fabrication. We addressed three major technical hurdles inherent to current approaches: 1) difficulty of compact integration; 2) need for real-time and power-efficient computations; 3) unavailability of commercial tiny actuators and motion mechanisms. The aim of this work was to provide enabling hardware technologies to achieve autonomy in tiny robots. We proposed a decentralized application-specific integrated circuit (ASIC) where each component is responsible for its own operation and autonomy to the greatest extent possible. The ASIC consists of electronics modules for the fundamental functions required to fulfill the desired autonomy: actuation, control, power supply, and sensing. The actuators and mechanisms could potentially be post-fabricated on the ASIC directly. This design makes for a modular architecture. The following components were shown to work in physical implementations or simulations: 1) a tunable motion controller for ultralow frequency actuation; 2) a nonvolatile memory and programming circuit to achieve automatic and one-time programming; 3) a high-voltage circuit with the highest reported breakdown voltage in standard 0.5 μm CMOS; 4) thermal actuators fabricated using CMOS compatible process; 5) a low-power mixed-signal computational architecture for robotic dynamics simulator; 6) a frequency-boost technique to achieve low jitter in ring oscillators. These contributions will be generally enabling for other systems with strict size and power constraints such as wireless sensor nodes.

Biodiversité des pollinisateurs dans les cannebergières : effets des pratiques culturales, du type de sol et de l'habitat naturel

Les pollinisateurs indigènes sont importants pour la production de canneberges. Ils sont pourtant menacés par les pratiques agricoles qui s’intensifient. Pour établir un plan de conservation efficace, une meilleure connaissance des facteurs intrinsèques aux exploitations est essentielle. L’objectif principal de cette étude était de déterminer la diversité et abondance des abeilles et syrphes retrouvées en cannebergières. Quinze fermes ont été échantillonnées selon la régie de culture, le type de sol et le type d’habitat naturel retrouvé près des cannebergières. Des pièges-bols disposés en transect ainsi que l’utilisation de filet entomologique ont été utilisés pour échantillonner les pollinisateurs. Au total, 135 espèces de pollinisateurs indigènes ont été capturées en 2013 et 2014. Le type de sol ainsi que l’habitat naturel influençaient les communautés de pollinisateurs, alors que la régie de culture ne les affectait pas. L’abeille Melitta americana, spécialiste du pollen de canneberge, a été capturée plus souvent dans les tourbières.

Application of GIS in potential beekeeping assessment: Case study of Montesinho Natural Park (Portugal)

Planners require solutions that address routine work needs and seems essential to improving efficiency and productivity. There are a great number of different factors related to beekeeper activity as well the quality and productivity of different bee products. The spatial analysis is a powerful tool for overlap and relates various levels of information on a map, and consequently a very useful for beekeeping activity planning. This work proposes and applies a methodology to potential beekeeping assessment in Montesinho Natural Park, a region in the northwest of Portugal. The beekeeping potential maps were developed with the following data sources: legal standards, vegetation, land use, topography, water resources, roads, electromagnetic fields, and some honey physico-chemical analysis. The design and implementation of spatial analysis model based on Geographic Information System (GIS) to beekeeping planning activities has already been described by Anjos et al (2014). Spatial analysis techniques allows to define the potential beekeeper map supporting the beekeeper management in this region. Anjos O, Silva G, Roque N, Fernandez P, 2014.

A crítica às mulheres no fr. 7 de Semónides de Amorgos

O poema de Semónides de Amorgos sobre as mulheres (Fr. 7 West) é o mais extenso fragmento preservado da poesia iâmbica grega da época arcaica. Nele o poeta apresenta uma reflexão pessimista de cariz misógino sobre o carácter feminino, numa narrativa original que cataloga dez tipos de mulher, oito baseadas em modelos animais (a porca, a raposa, a cadela, a burra, a doninha, a égua, a macaca e a abelha) e dois em elementos da natureza (a terra e o mar). Pretende-se demonstrar, neste estudo, que essa caracterização tipológica era inovadora e respondia a uma dupla finalidade: satírica e humorística. Uma vez que o poema se destinaria a um contexto simpótico, um espaço tipicamente masculino, a mulher e a sua natureza constituiriam uma temática que levaria o homem a reflectir, de um modo simultaneamente sério e divertido, sobre a sua própria condição.

Small strain elastic behaviour of unsaturated soil investigated by bender/extender element testing

The aim of this project was to investigate very small strain elastic behaviour of soils under unsaturated conditions, using bender/extender element (BEE) testing. The behaviour of soils at very small strains has been widely studied under saturated conditions, whereas much less work has been performed on very small strain behaviour under unsaturated conditions. A suction-controlled double wall triaxial apparatus for unsaturated soil testing was modified to incorporate three pairs of BEEs transmitting both shear and compression waves with vertical and horizontal directions of wave transmission and wave polarisation. Various different techniques for measuring wave travel time were investigated in both the time domain and the frequency domain and it was concluded that, at least for the current experimental testing programme, peak-to-first-peak in the time domain was the most reliable technique for determining wave travel time. An experimental test programme was performed on samples of compacted speswhite kaolin clay. Two different forms of compaction were employed (i.e. isotropic and anisotropic). Compacted kaolin soil samples were subjected to constant suction loading and unloading stages at three different values of suction, covering both unsaturated conditions (s= 50kPa and s= 300kPa) and saturated conditions (s=0). Loading and unloading stages were performed at three different values of stress ratio (η=0, η=1 and η=-1 ). In some tests a wetting-drying cycle was performed before or within the loading stage, with the wetting-drying cycles including both wetting-induced swelling and wetting-induced collapse compression. BEE tests were performed at regular intervals throughout all test stages, to measure shear wave velocity Vs and compression wave velocity Vp and hence to determine values of shear modulus G and constrained modulus M. The experimental test programme was designed to investigate how very small strain shear modulus G and constrained modulus M varied with unsaturated state variables, including how anisotropy of these parameters developed either with stress state (stress-induced anisotropy) or with previous straining (strain-induced anisotropy). A new expression has been proposed for the very small strain shear modulus G of an isotropic soil under saturated and unsaturated conditions. This expression relates the variation of G to only mean Bishop’s stress p* and specific volume v, and it converges to a well-established expression for saturated soils as degree of saturation approaches 1. The proposed expression for G is able to predict the variation of G under saturated and unsaturated conditions at least as well as existing expressions from the literature and it is considerably simpler (employing fewer state variables and fewer soil constants). In addition, unlike existing expressions from the literature, the values of soil constants in the proposed new expression can be determined from a saturated test. It appeared that, in the current project at least, any strain-induced anisotropy of very small strain elastic behaviour was relatively modest, with the possible exception of loading in triaxial extension. It was therefore difficult to draw any firm conclusion about evolution of strain-induced anisotropy and whether it depended upon the same aspects of soil fabric as evolution of anisotropy of large strain plastic behaviour. Stress-induced anisotropy of very small strain elastic behaviour was apparent in the experimental test programme. An attempt was made to extend the proposed expression for G to include the effect of stress-induced anisotropy. Interpretation of the experimental results indicated that the value of shear modulus was affected by the values of all three principal Bishop’s stresses (in the direction of wave transmission, the direction of wave polarisation and the third mutually perpendicular direction). However, prediction of stress-induced anisotropy was only partially successful, and it was concluded that the effect of Lode angle was also significant.
