Objetivos y contenidos de un programa de educación emocional para personas mayores. Emociona’t

Se ha entendido la educación emocional cómo un proceso de carácter preventivo y de desarrollo humano, más que de tratamiento. Los efectos a largo plazo de la educación emocional conllevan beneficios como: aumento de las habilidades sociales y de las relaciones interpersonales satisfactorias, disminución de pensamientos autodestructivos, mejora de la autoestima, mejor adaptación familiar y social, disminución de la tristeza y sintomatología depresiva, disminución de la ansiedad y del estrés, disminución de los desordenes relacionados con la comida, entre otros. Dado el carácter preventivo de la educación emocional se ha apostado por la intervención grupal mediante programas educativos. En este artículo se presenta los objetivos y los contenidos que constituyen un programa de educación emocional para personas mayores. Dicho programa lleva ya implementándose en el Ayuntamiento de Lleida desde hace dos años en distintos clubs de jubilados. El programa que desarrollamos está estructurado en 5 bloques temáticos: a) conciencia emocional; b) regulación emocional; c) autoestima; d) habilidades socioemocionales, y e) habilidades de vida. La educación emocional nos ayuda a vivir de forma activa y satisfactoria a través de la reflexión sobre nuestras formas de sentir, pensar y comportarnos.

Avaliação da aplicação exógena de poliaminas no crescimento de calos de mangabeira (Hancornia speciosa Gomes)

Este trabalho teve como objetivo estudar o efeito das poliaminas espermidina e espermina no crescimento de calos Hancornia speciosa Gomes. Calos com 0,5 cm de diâmetro foram inoculados em meio Murashige & Skoog (1962) (MS) a 50% + 100 mg L-1 de caseína hidrolisada + 200 mg L-1 de levedura de cerveja, variando os tratamentos:A: 1 mmol de espermina + 2 mg L-1 de 2,4-D (ácido 2,4 diclorofenoxiacético) + 0,5 mg L-1 de NAA (ácido naftalenoacético); B: 1 mmol de espermidina + 2 mg L-1 de 2,4-D + 0,5 mg L-1 de NAA; C: 2 mg L-1 de 2,4-D + 0,5 mg L-1 de NAA. Não houve influência das poliaminas no crescimento dos calos. observou-se, nos calos tratados com espermidina, maior concentração celular de putrescina (582,37 µg g mf-1) aos 60 dias, maior teor de espermidina (502,54 µg g mf-1) e espermina (868,53 µg g mf-1) aos 40 dias de cultivo, quando se aplicou a própria poliamina. Conclui-se que a aplicação exógena de poliaminas em Hancornia speciosa não proporciona aumento no crescimento de calos. A oxidação promovida por longos períodos de cultivo in vitro induz aumento nos níveis de putrescina.

Effect of prestorage curing on storage life, internal and external qualities of sweet orange (Citrus sinensis)

Orange fruits from two seasons, in April and August 2006 representing late 2005 and early 2006 harvests respectively were cured in hot air at 36-37(0)C to 1%, 3%, 5% and 7% weight loss before storage at 28(0)C and 86% relative humidity (RH). The fruits were observed for incidence of decay, further weight loss, juice content, firmness or softening of the peel, total soluble solids (TSS), pH, titratable acidity, and colour during storage. Curing reduced the incidence of decay. All control fruits were rotten by day 21 in August harvest while 22.5% of the control was rotten by day 56 in the April harvest. Storage life was extended beyond 56 days in fruits cured with 1, 3, 5 and 7% in April harvest as there was no decay throughout, while decay incidence in August harvest was 88.9, 61.1, 22.2 and 31.3% in 1, 3, 5 and 7% respectively. Penicillium digitatum, Phytophthora sp., Alternaria citri and Collectotrichum gloeosporioides were among decay causing moulds detected. Control fruits lost more weight during storage than cured fruits did. Fruit rind hardening was more noticed in the control and those cured to 1% weight loss, especially from the April harvest. It was insignificant in other treatments in both trials. Titratable acidity, pH, juice content and TSS were not affected by the treatment. Colour change to yellow was however retarded by curing. Curing to 5% weight loss was best for decay control and quality retention.

Characterization of rambutan (Nephelium lappaceum) fruits from outstanding mexican selections

Fruits of five regional selections of rambutan (Nephelium lappaceum L.) were characterized to identify those with international marketing quality to promote their propagation in Mexico, improvement and conservation in germoplasm bank. The fruits were harvested in June, July, and August 2008 and, after each harvest, were assessed for shape (length/diameter), firmness, fruit weight, number of fruits per kilogram, weight and percentage of pericarp, seed and aril, total soluble solids, total sugars, vitamin C content, pH, and titratable acidity. In addition, a sensorial evaluation was carried out with 31 panelists who graded each selection for color, sweetness, and acidity. Fruits of five selections were ovoid, and with the following characteristics: firmness values from 43.7 to 51.0 N, fruit weight ranged from 22.4 to 34.7 g, registering from 28.9 to 45.0 fruits per kg; pericarp weight from 10.5 to 17.3 g (45.9 to 49.9% of the total fruit weight); total seed weight from 2.2 to 2.5 g (7.0 to 10.0%); average arils weight from 8.9 to 13.1 g (37.5 to 41.4%). The fruits had high contents of total soluble solids (17.8 to 20.4 ºBrix), total sugars (211.95 to 242.70 mg/100g in the edible portion), vitamin C (37.9 to 69.1 mg/100 g), pH 5.0, and titratable acidity of 0.20 to 0.28%. The fruits from the RT-01 and RT-05 selections had better attributes in fruit weight, total soluble solids and titratable acidity and were better accepted by the panelists. Harvest date significantly affects rambutan fruit quality; at the middle and end of the season harvested fruits had better qualitative characteristics for the marketing.

Pathogenic attack and carbon reallocation in soybean leaves (Glycine max. L.): Reinitiation of the glyoxylate cycle as a defence reaction

Pathogenic attack by the fungus Botrytis cinerea (primary pathogen) on soybean leaves (Glycine max. L.; cv. Maple arrow) results in a hypersensitive response (necrotising infected leaves), in the establishment of local acquired resistance, as well as in the systemic induction of genes coding for pathogenesis-related proteins. It now appears that, concomitantly with these already well documented defence reactions, the pathogenic attack also induces the carbon reallocation mechanism based on the reinitiation of the glyoxylate cycle (pseudo-senescence of the infected leaves).

Composição iônica majoritária de águas de chuva no centro da cidade de São Paulo

The chemical composition of rainwater samples collected from March 2002 to February 2003 in downtown São Paulo city (Universidade Presbiteriana Mackenzie) is presented. Potentiometric and conductimetric measurements were used to evaluate the [H+] and the total ionic content. Major anions and cations were determined by ion chromatography with conductivity detection. The rainwater was acidic with a mean pH of 4.99. The volume weighted means, VWM, of the anions nitrate, acetate and sulfate were, respectively, 21.2, 16.9 and 12.4 µmol L-1. Ammonium was the most abundant ion with a VWM of 37.6 µmol L-1. The contribution of each anion to the free acidity potential decreases in the following order: SO4(2-) (28.8%), CH3COO- (24.7%), NO3- (22.8%), Cl- (13.4%), HCOO- (7.7%) and C2O4(2-) (2.5%). The relative contribution of the weak organic acids to the free acidity was significant, 34.9%.

Determinação de manganês em material particulado atmosférico de ambientes de trabalho utilizando eletrodo de diamante dopado com boro e voltametria de onda quadrada com redissolução catódica

A boron-doped diamond electrode is used for determination of Mn(II) in atmospheric particulate matter by square wave cathodic stripping voltammetry. The analytical curve was linear for Mn(II) concentrations between 5.0 and 37.5 µg L-1, with quantification limit of 3.6 µg L-1. The precision was evaluated by the relative standard deviation, with values between 5.1% and 9.3%. The electrode is free of adsorption, minimizing memory effects. Samples collected in the workplace atmosphere of a foundry had Mn(II) concentrations between 0.4 and 4 µg m-3. No significant differences were observed between the proposed method and inductively coupled plasma optical emission spectroscopy.

Concentrated Winding Multiphase Permanent Magnet Machine Design and Electromagnetic Properties – Case Axial Flux Machine

Concentrated winding permanent magnet machines and their electromagnetic properties are studied in this doctoral thesis. The thesis includes a number of main tasks related to the application of permanent magnets in concentrated winding open slot machines. Suitable analytical methods are required for the first design calculations of a new machine. Concentrated winding machines differ from conventional integral slot winding machines in such a way that adapted analytical calculation methods are needed. A simple analytical model for calculating the concentrated winding axial flux machines is provided. The next three main design tasks are discussed in more detail in the thesis. The magnetic length of the rotor surface magnet machines is studied, and it is shown that the traditional methods have to be modified also in this respect. An important topic in this study has been to evaluate and minimize the rotor permanent magnet Joule losses by using segmented magnets in the calculations and experiments. Determination of the magnetizing and leakage inductances for a concentrated winding machine and the torque production capability of concentrated winding machines with different pole pair numbers are studied, and the results are compared with the corresponding properties of integral slot winding machines. The thesis introduces a new practical permanent magnet motor type for industrial use. The special features of the machine are based on the option of using concentrated winding open slot constructions of permanent magnet synchronous machines in the normal speed ranges of industrial motors, for instance up to 3000 min-1, without excessive rotor losses. By applying the analytical equations and methods introduced in the thesis, a 37 kW 2400 min-1 12-slot 10-pole axial flux machine with rotor-surfacemounted magnets is designed. The performance of the designed motor is determined by experimental measurements and finite element calculations.
