One possible application for the excess of glycerol, which is an exceeding byproduct in biodiesel industry, was used as carbon and energy sources for bioproducts synthesis. This work aims to evaluate biosurfactant production from glycerol by Pseudomonas aeruginosa EQ 109 isolated from crude oil-contaminated soil. Factorial design 2^3 was utilized to optimize the amount of biosurfactant produced, by using pH （A）, initial biomass concentration （B）, and initial glycerol concentration （C） as independent factors. The experiments were carried out in flasks containing 100 mL of mineral medium. Biosurfactant production was monitored by increase of the emulsification of aviation kerosene （E24） and surface tension reduction （STr）. The results have shown that, at pH = 7.0, in order to increase E24, variables as B and C are the most influential, leading to a maximum value of E24 = 79%, as well as for an increase of GC （GCmax = 49%）. STR was the variable with the best correlation factor for the proposed linear model （R2=0.96） and its maximum value was 48%. Xfwas not significant to the model, although it was influenced by pH and C, with C = 40g/L （Xfmax = 4.56 g/L）.

A method for adsorption involving banana peel (BP) was studied to remove the pollutant acetylsalicylic acid (ASA) in aqueous medium. The results show that bioadsorbent has satisfactory maximum adsorption capacity (2.29 mg/g) for removing this analgesic and anti-inflammatory drug in aqueous solution (pH 7.0) using the Langmuir mathematical model. The tested concentrations of this pollutant were higher than the levels commonly found in the aquatic environment. This and other results suggest the BP as an alternative to ASA removal in water contaminated with pharmaceuticals pollutants.

This paper presents a comparative study on Magnetic-Dispersion based Energy Harvesting Systems (MD-EHS) on electrical conductors that supply power for a three-phase AC motor. It introduces two MD-EHS which are based on magnetic cores of different material, named, nanocrystalline, ferrite and iron powder. The first one consists of harvesting energy from magnetic flux through three symmetrical magnetic cores installed on each power conductors of a three-phase AC motor. The second one consists of a single magnetic core for harvesting energy from magnetic flux of only one of these conductors. Both ones have an AC/DC converter and a variable resistor based load. Experimental results have agreed with the theoretical analysis and show that the first proposed MD-EHS is capable of supplying 14 times more energy than the second MD-EHS, considering nanocrystalline cores and phase current of 3 A, and 7.5 times more energy, considering ferrite cores and phase current of 9 A. Such energy can be applied to various low-power devices, especially in wireless sensor network.

Introduction: In the last few years, there has been a growth in the number of cases of people with HIV/AIDS aged 50 years and older. This is explained by the inclusion of antiretroviral therapy, increased survival of patients as well as by the growth in the number of infected people in this age group. Objective: To analyze the association between sociodemographic and clinical characteristics with the QOL of people aged 50 years or older living with HIV/AIDS. Methods: Quantitative, cross-sectional study conducted in the outpatient clinic of a reference hospital in Natal, Brazil. The sample consisted of 50 subjects, aged over 50, seropositive for HIV and with cognitive conditions to answer the interview. Authors used sociodemographic and clinical evaluation tools and the WHOQOL-HIV BREF scale. Results: Sociodemographic: respondents’ average age was 57.32 years, 58% male, 38% brown, 26% incomplete primary education, 46% single, 56% retired, 70% with a monthly income of 1 to 2 minimum wages and 70% Catholic. Clinical: 60% have a partner without the diagnosis of HIV/AIDS;62% had not been hospitalized previously;66% did not have opportunistic infections;40% indicated that there was a change in the physiological sexual function after the onset of the disease. Quality of life: people living with HIV/AIDS had low scores in QOL domains. When associating sociodemographic and clinical aspects, it was observed that they had associations with QOL, especially in regard to education, income, religion, change in sexual function and feelings. Conclusion: The spiritual domain was highlighted with the best performance, collaborating to facing, hope and resilience of HIV/AIDS.

Aim: To describe the process of follow-up in primary care facilities where the Integrated Management of Childhood Illness (IMCI) strategy was implemented. IMCI was developed by WHO and UNICEF as an integrated approach to manage sick children under 5 y of age and aims to reducemortality and morbidity. Methods: From August 2001 to February 2002, 229 sick children who had a health condition included in the IMCI case management guidelines were seen in six family health care facilities in Brazil. We analysed the care provided to 153 children who were recommended for a 2-or 5-d follow-up visit. Children who did not return were visited and assessed at home. Results: Only 87 children (56.9%) timely returned for follow-up: 70 had improved, eight presented the same health conditions, five were worse and four had a new problem. The main reasons given for not returning for follow-up were: the child had improved (35.1 %) and other family priorities (47.4%). Home visits showed that, although most children had improved (n = 49), some had a new health problem and one child was sick enough to be referred. Prescription of antibiotics was associated with increased probability of returning for a follow-up visit (RR = 1.64 1.22-2.20 ,p = 0.001). Conclusion: Adherence to followup was just over 50%, mostly because the condition had already resolved, but some children were still sick and needed intervention. Training on counselling on the recognition of danger signs and when to return for a follow-up visit must be reinforced.

Functional abdominal pain disorders(FAPDs) are an important and prevalent cause of functional gastrointestinal disorders among children, encompassing the diagnoses of functional dyspepsia, irritable bowel syndrome, abdominal migraine, and the one not previously present in Rome Ⅲ, functional abdominal pain not otherwise specified. In the absence of sufficiently effective and safe pharmacological treatments for this public problem, non-pharmacological therapies emerge as a viable means of treating these patients, avoiding not only possible side effects, but also unnecessary prescription, since many of the pharmacological treatments prescribed do not have good efficacy when compared to placebo. Thus, the present study provides a review of current and relevant evidence on non-pharmacological management of FAPDs, covering the most commonly indicated treatments, from cognitive behavioral therapy to meditation, acupuncture, yoga, massage, spinal manipulation, moxibustion, and physical activities. In addition, this article also analyzes the quality of publications in the area, assessing whether it is possible to state if non-pharmacological therapies are viable, safe, and sufficiently well-based for an appropriate and effective prescription of these treatments. Finally, it is possible to observe an increase not only in the number of publications on the non-pharmacological treatments for FAPDs in recent years, but also an increase in the quality of these publications. Finally, the sample selection of satisfactory age groups in these studies enables the formulation of specific guidelines for this age group, thus avoiding the need for adaptation of prescriptions initially made for adults, but for children use.
