A Mata Atlântica é um dos ambientes mais ricos e ameaçados do mundo, o que deveria ter estimulado em muito o estudo e a conservação do Bioma, mas a fauna de Hymenoptera permanece ainda relativamente pouco conhecida. Em especial, a fauna de abelhas da floresta ombrófila densa é pouco estudada em comparação à fauna das áreas abertas brasileiras. O projeto temático "Biodiversidade de Hymenoptera e Isoptera: riqueza e diversidade ao longo de um gradiente latitudinal na Mata Atlântica - a floresta úmida ...

Lithium-ion batteries (LIBs) are the most widely used energy storage system because of their high energy density and power, robustness, and reversibility, but they typically include an electrolyte solution composed of flammable organic solvents, leading to safety risks and reliability concerns for high-energy-density batteries. A step forward in Li-ion technology is the development of solid-state batteries suitable in terms of energy density and safety for the next generation of smart, safe, and ...

The increased demand of electronic devices promotes the development of advanced and more efficient energy storage devices, such as batteries. Lithium-ion batteries (LIBs) are the most studied battery systems due to their high performance. Among the different battery components, the separator allows the control of lithium ion diffusion between the electrodes. To overcome some drawbacks of liquid electrolytes, including safety and environmental issues, solid polymer electrolytes (SPEs) are being developed. ...

Taking into consideration environmental issues and additive manufacturing technologies, the development of advanced UV curable polymers and polymer composites is an area of increasing interest. In this scope, polyurethane acrylate (PUA) composites with Indium Tin Oxide (ITO) were produced in order to tune morphology, optical, thermal, mechanical and dielectric properties. It is shown that ITO particles are well dispersed within the polymer matrix and that the polymerization rate and the UV curing ...

Salicornia spp. are traditionally used in Asia as food, forage and medicine. In the West, its popularity has been increasing as an alternative to salt. Nevertheless, the potential presence of contaminants needs to be considered. Hence this study, which aimed to investigate the presence of potentially mycotoxigenic fungi and the occurrence of aflatoxins and ochratoxin A in Salicornia sampled in Portugal. Fungi isolation was performed by the direct plating technique in selective media. The mycotoxins ...

Tick-borne diseases (TBDs) are very important in relation to domestic ruminants, but their occurrence among wild ruminants, mainly in the African buffalo Syncerus caffer, remains little known. Molecular diagnostic methods were applied to detect Anaplasma marginale, Anaplasma centrale, Anaplasma phagocytophilum, Ehrlichia ruminantium and Ehrlichia chaffeensis in 97 blood samples of African buffalo captured at the Marromeu Reserve in Mozambique. Molecular detection of agents belonging to the family ...

Background The demographic transition of populations from rural areas to large urban centers often results in a disordered occupation of forest remnants and increased economic pressure to develop high-income buildings in these areas. Ecological and socioeconomic factors associated with these urban transitions create conditions for the potential transmission of infectious diseases, which was demonstrated for Chagas disease. Methodology/Principal Findings We analyzed 930 triatomines, mainly Triatoma ...

Susceptibility during fasting has been reported for the common vampire bat (Desmodus rotundus), to the point of untimely deaths after only 2-3 nights of fasting. To investigate the underlying physiology of this critical metabolic condition, we analyzed serum insulin levels, pancreatic islets morphometry and immunocytochemistry (ICC), static insulin secretion in pancreas fragments, and insulin signaling mechanism in male vampire bats. A glucose tolerance test (ipGTT) was also performed. Serum insulin ...

Introduction: This study attempts to demonstrate that kinematic recordings of finger movements help explain the well-known effects of age, education, and sex on the Halstead Finger Tapping Test (HFTT). Method: High-speed kinematic recordings were obtained on 107 healthy adults (ages 21 to 80 years) while they performed a modified version of the Halstead Finger Tapping Test (HFTT). The number of "valid" taps and "invalid" taps (i.e., lever movements that did not produce an increase in the mechanical number ...

Background: Cardiac autonomic modulation (CAM) is impaired in patients with stable COPD. Exacerbation aggravates the patients' health status and functional capacity. While the clinical and functional effects of exacerbation are known, no studies investigated CAM during exacerbation and whether there is a relationship between CAM and functional capacity and dyspnea. Methods: Thirty-two patients with moderate to severe COPD were enrolled into two groups: stable COPD (GSta, n=16) and acute exacerbation ...

This study evaluated the effect of ethanol on the repair in calvaria treated with beta-tricalcium phosphate (β-TCP). Forty rats were distributed into 2 groups: Water group (CG, n = 20) and Alcohol Group (AG, n = 20), which received 25% ethanol ad libitum after an adaptation period of 3 weeks. After 90 days of liquid diet, the rats were submitted to a 5.0 mm bilateral craniotomy in the parietal bones; the left parietal was filled with β-TCP (CG-TCP and AG-TCP) and the contralateral only with blood clot (CG- ...
