Iron-Fortified Drinking Water Studies for the Prevention of Children's Anemia in Developing Countries
Anemia and iron deficiency should receive special attention considering their high prevalence and serious consequences. For prevention, globally it is recommended to increase dietary iron intake, iron fortification of industrialized foods, and medical iron supplementation.
Food fortification for the prevention of iron deficiency in developing countries should consider carriers locally available and consumed daily, requiring limited infrastructure and technology. Drinking water is the iron carrier we have been working for years for the prevention of iron deficiency and anemia in small children in Brazil. It was shown that studies with iron-fortified drinking water were proved to be effective on children's anemia prevention. Water is found everywhere, consumed daily by everyone may be easily fortified with simple technology, is low priced and was effective on the prevention of children's anemia. Fortification of drinking water with iron was locally implemented with the direct participation of the government and community. Government authorities, health personnel and population were part of the project and responsible for its community implementation. The mayor/municipality permitted and supported the proposal to supply it to children at their day-care centers. To keep the children drinking water iron fortified supply an officially authorized legislation was also approved
Quantitative methods and studies of psychic disorders and job satisfaction of teachers of the prison system in the Amazon, Brazil
Objective: To analyze the level of mental suffering and the level of job satisfaction in 85% of the teachers of the state education network who work in the prison units in the city of Porto Velho, Rondonia, Amazonia, Brazil. Method: This is a cross-sectional study; and for the data collection, three structured instruments were used: the sociodemographic questionnaire; the Self-Report-Questionnaire Questionnaire (SRQ-20), and the OSI-Occupational Stress Indicator Scale, Measured by Likert Scale. Results: The results showed that 12.5% of the teachers presented minor psychic disorders, considered as indicators of evidence of mental distress. Satisfaction in the work had indexes similar to those found in the literature, presenting the highest proportion in the intermediate variables, that is, their highest frequencies are in the range of some dissatisfaction, with 32.28%; and 32.04% with some satisfaction. The highest index of dissatisfaction is in the variable that refers to salary, with 29.4%. Conclusions: From the results, it is possible to indicate a possible association between job satisfaction and mental suffering. This study will provide great reflections on the teaching practice in prison units and will contribute to the occupational health of teachers working in prison units, allowing a rethinking of public policies in education and health in the context of the prison system
A near-infrared study of the multi-phase outflow in the type-2 quasar J1509+0434
Based on new near-infrared spectroscopic data from the instrument EMIR on the 10.4 m Gran Telescopio Canarias (GTC) we report the presence of an ionized and warm molecular outflow in the luminous type-2 quasar J150904.22+043441.8 (z = 0.1118). The ionized outflow is faster than its molecular counterpart, although the outflow sizes that we derive for them are consistent within the errors (1.34±0.18 kpc and 1.46±0.20 kpc respectively). We use these radii, the broad emission-line luminosities and in the case of the ionized outflow, the density calculated from the trans-auroral [OII] and [SII] lines, to derive mass outflow rates and kinetic coupling efficiencies. Whilst the ionized and warm molecular outflows represent a small fraction of the AGN power (≤0.033% and 0.0001% of Lbol respectively), the total molecular outflow, whose mass is estimated from an assumed warm-to-cold gas mass ratio of 6× 10−5, has a kinetic coupling efficiency of ∼1.7%Lbol. Despite the large uncertainty, this molecular outflow represents a significant fraction of Lbol and it could potentially have a significant impact on the host galaxy. In addition, the quasar spectrum reveals bright and patchy narrow Paα emission extending out to 4″ (8 kpc) South-East and North-West from the active nucleus.Includes Horizon 202
Removal of the hormones 17β-estradiol and 17α-ethinylestradiol from aqueous solutions employing a decomposed peat as adsorbent material
REMOVAL OF THE HORMONES 17b-ESTRADIOL AND 17a-ETHINYLESTRADIOL FROM AQUEOUS SOLUTIONS
EMPLOYING A DECOMPOSED PEAT AS ADSORBENT MATERIAL. This paper describes the adsorption of 17b-estradiol (E2)
and 17a-ethinylestradiol (EE2) from aqueous solution by decomposed peat. The peat presented a good adsorption process, close to
76.2% for E2 removal and approximately 55.0% for EE2. Moreover, the results indicated a probable multi-layered process. Adsorption
isotherms were well fitted by Freundlich model. The data were evaluated considering the pseudo-first-order and pseudo-second-order
approaches, being the second more significant mechanism in the rate-controlling step. Thermodynamic data revealed that hormones
adsorption onto peat is spontaneous under the employed experimental conditions. The results confirmed the potential of this adsorbent
to be employed for effluents treatment

Herbage Accumulation and Mass in Massai Grass Plots Mixed with Forage Peanut and Fertilized with Nitrogen
The objective of this work was to evaluate herbage accumulation and mass during the growing season of Massai grass mixed with peanut forage and fertilized with nitrogen. The work was carried out at Federal Rural University of Rio de Janeiro, Brazil, from 11/2021 to 03/2022. A randomized block experimental design was used, in plots of Massai grass Megathyrsus maximus, in a factorial arrangement, with seven replications. Four treatments formed by the combination of the presence or absence of Archis pintoi and nitrogen fertilization (0 and 50 kg ha-1 of N). Canopy heights of the plots were evaluated weekly and when they reached values of about 50 cm two samples were collected and the total herbage accumulation and mass were calculated. The treatments without nitrogen fertilization and legume had the lowest herbage accumulation and mass (5,080 and 2,060 kg ha-1 of DM, respectively), when compared to the plots that had nitrogen fertilization and legume. The treatments with or without legume but with nitrogen fertilization had the same herbage accumulation and mass (9,775 and 2,630 kg ha-1 of DM, respectively). Thus, the presence of the legume resulted in greater herbage accumulation and mass in relation to those plots without legume and nitrogen fertilization. However, when nitrogen fertilization was performed no additive effect with the presence of the legume was observed, indicating that the nitrogen fertilization somehow inhibited the benefit of the legume on forage production. So, based on the short-term results obtained, the use of nitrogen fertilization or the use of forage peanuts should be done separately

Physical Exercise Restores the Generation of New born Neurons in an Animal Model of Chronic Epilepsy
Neurogenesis impairment is associated with the chronic phase of the epilepsy in humans and also observed in animal models. Recent studies with animal models have shown that physical exercise is capable of improving neurogenesis in adult subjects, alleviating cognitive impairment and depression. Here, we show that there is a reduction in the generation of newborn granule cells in the dentate gyrus of adult rats subjected to a chronic model of epilepsy during the postnatal period of brain development. We also show that the physical exercise was capable to restore the number of newborn granule cells in this animals to the level observed in the control group. Notably, a larger number of newborn granule cells exhibiting morphological characteristics indicative of correct targeting into the hippocampal circuitry and the absence of basal dendrite projections was also observed in the epileptic animals subjected to physical exercise compared to the epileptic animals. The results described here could represent a positive interference of the physical exercise on the neurogenesis process in subjects with chronic epilepsy. The results may also help to reinterpret the benefits of the physical exercise in alleviating symptoms of depression and cognitive dysfunction.Fapemig (Fundacao de Amparo a Pesquisa do Estado de Minas Gerais)CNPq (Conselho Nacional de Desenvolvimento Cientifico e Tecnologico)FAPESP (Fundacao de Amparo a Pesquisa do Estado de Sao Paulo)INNT (Instituto Nacional de Neurociencia Translacional)CAPES (Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior)Univ Fed Sao Joao del Rei, Dept Engn Biossistemas, Lab Neurociencia Expt Computac, Sao Joao Del Rei, BrazilHosp Israelita Albert Einstein, Inst Cerebro, Sao Paulo, BrazilUniv Mogi das Cruzes, Nucleo Pesquisas Tecnol, Mogi Das Cruzes, BrazilUniv Fed Sao Paulo UNIFESP, Dept Fisiol, Escola Paulista Med, Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, Disciplina Neurol Expt, Escola Paulista Med, Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, Dept Fisiol, Escola Paulista Med, Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, Disciplina Neurol Expt, Escola Paulista Med, Sao Paulo, BrazilWeb of Scienc
