Crespo Montero,Rodolfo; Contreras Abad,María Dolores; Casas Cuesta,Rafael; Mu?oz Benítez,Inmaculada; Moreno Delgado,María Carmen; Suanes Cabello,Lourdes;
Revista de la Sociedad Espa?ola de Enfermería Nefrológica , 2011, DOI: 10.4321/S1139-13752011000100007
Abstract: the aim of this study was to analyze the duration and causes of removing complications for temporary catheters for haemodialysis. we studied 1409 catheters which were implanted on 608 patients in haemodialysis chronic (60.9 ± 15.5 years, 341 females (56%) and 267 males (44%). 280 (46%) patients received 1 catheter and 144 (24%) 2 catheters. we analyzed 546 catheters retired exclusively by complications. mean duration of the catheters (n=546) of was 21±36 days. the main catheters complications that forced their retreat were: 75% for deficit blood flow rate, 11% infection, 6%, for loss of surgical suture, 3% for occlusion, 3% for elbowed. the deficit blood flow rate appeared to the 18 ± 34 days and the la infection to the 29±50 days. mean duration of the catheters was of the 16±32 days for the left side and 23±38 for right side (p<0.0001). when we compared the different blood vessel, mean duration of the catheters was of the 25.3±43 days for the jugular, 17.5±23 for the subclavia, and 11.9±10 days for the femoral, being significant differences among jugular-subclavia and femoral vein (p<0.05). when comparing the duration, among a single lumen vs dual lumen, in catheters retired by complications, they were not significant differences (multivariate analysis). we can conclude that the duration, of the catheters placed in jugular or subclavia veins and right side is superior to the placed in femoral vein or left side, being recommended its use therefore as temporary access in hd, also facilitating the patient's mobility and ambulatory dialysis. we have not found, at least in our study, differs in the duration among the single lumen versus dual lumen catheters.
Growth dynamics and yield of melon as influenced by nitrogen fertilizer
Castellanos, María Teresa;Cabello, María Jesús;Cartagena, María del Carmen;Tarquis, Ana María;Arce, Augusto;Ribas, Francisco;
Scientia Agricola , 2011, DOI: 10.1590/S0103-90162011000200009
Abstract: nitrogen (n) is an important nutrient for melon (cucumis melo l.) production. however there is scanty information about the amount necessary to maintain an appropriate balance between growth and yield. melon vegetative organs must develop sufficiently to intercept light and accumulate water and nutrients but it is also important to obtain a large reproductive-vegetative dry weight ratio to maximize the fruit yield. we evaluated the influence of different n amounts on the growth, production of dry matter and fruit yield of a melon 'piel de sapo' type. a three-year field experiment was carried out from may to september. melons were subjected to an irrigation depth of 100% crop evapotranspiration and to 11 n fertilization rates, ranging 11 to 393 kg ha-1 in the three years. the dry matter production of leaves and stems increased as the n amount increased. the dry matter of the whole plant was affected similarly, while the fruit dry matter decreased as the n amount was increased above 112, 93 and 95 kg ha-1, in 2005, 2006 and 2007, respectively. the maximum leaf area index (lai), 3.1, was obtained at 393 kg ha-1 of n. the lowest n supply reduced the fruit yield by 21%, while the highest increased the vegetative growth, lai and leaf area duration (lad), but reduced yield by 24% relative to the n93 treatment. excessive applications of n increase vegetative growth at the expense of reproductive growth. for this melon type, rates about 90-100 kg ha-1 of n are sufficient for adequate plant growth, development and maximum production. to obtain fruit yield close to the maximum, the leaf n concentration at the end of the crop cycle should be higher than 19.5 g kg-1.

Hydro-Adsorption Study by Dynamic Laser Speckle of Natural Zeolite for Adsorbent and Fertilizer Applications  [PDF]
Ruth Dary Mojica-Sepulveda, Luís Joaquín Mendoza-Herrera, María Florencia Agosto, Eduardo Grumel, Delia Beatriz Soria, Carmen Inés Cabello, Marcelo Trivi
Advances in Chemical Engineering and Science (ACES) , 2016, DOI: 10.4236/aces.2016.65049
Abstract: The dynamic behavior caused by hydro-adsorption process of materials based on a rich mineral clinoptilolite together with their acidic, basic and calcinated forms has been studied by the dynamic laser speckle (DLS) technique. We propose a modified Peleg’s equation to improve fitting of DLS data. Textural (BET), structural (XRD) and spectroscopic (FTIR) properties were also studied and compared. We demonstrated that DLS was the most sensitive, simple and inexpensive method for comparing the performance of adsorptive materials with slightly modified surfaces. It also allowed the correlation with physicochemical properties.

Abstract: Este artículo estudia el discurso periodístico de La Verdad en el proceso político de la transición espa ola a la democracia, concretamente en el periodo comprendido entre la proclamación del rey y la aprobación de la Ley para la Reforma Política. A través de un análisis de contenido cualitativo de 30 editoriales se pretende mostrar los argumentos utilizados por la Editorial Católica para promover los valores democráticos en el espacio público durante los primeros meses de la Transición. This article deals with the journalistic discourse of La Verdad newspaper during the political process of the Transition in Spain to democracy, with special focus on the period from the proclamation of the King to the passing of the Political Reform Act. A qualitative analysis of 30 leaders is used to show the arguments employed by the Catholic Publication to promote democratic values within the public sphere during the first months of the Transition.
Propiedad y control en joint ventures internacionales: Un caso de estudio entre una multinacional espa ola y una empresa estatal china

Universia Business Review , 2012,
Abstract: La literatura ha resaltado el papel de la participación en el capital de la joint venture internacional como mecanismo de control. Sin embargo, un socio no puede confiar exclusivamente en dicha participación para garantizar el éxito de su estrategia. Mediante el estudio de un caso, el presente trabajo pone de relieve que, aun en posesión de la mayoría del capital, un socio debe recurrir a otros mecanismos de control, entre los que tienen especial importancia las políticas de personal relativas a los puestos directivos de la joint venture internacional.
Comparation of the eutectic mixture of lidocaine/prilocain versus benzocaine gel in children  [PDF]
Ana María Leyda, Carmen Llena
Open Journal of Stomatology (OJST) , 2011, DOI: 10.4236/ojst.2011.13014
Abstract: Objective: To compare the anesthetic effect of a non commercial eutectic mixture of 4% lidocaine/ prilocaine (PLO 4%) and 20% benzocaine gel (Hurricaine®), as topical anesthetic, prior to inferior alveolar nerve block and buccal infiltration anesthe-sia in 5-12 year old children. Study design: Infiltrative anesthesia was applied in 50 children, divided in two groups (n = 25) using PLO 4% and Hurricaine® as topical anesthesia prior to infiltration. Physical reac-tions were registered using the Sound-Eyes- Motor Scale. Physiological changes expressed by ar-terial pressure and heart rate. Subjective pain re-sponse was scored on a Facial Image Scale. Physical physiological and subjective response was related to the type of topical anesthetic, age and sex using χ2 and Mann-Whitney U test. Results: Physical responses to puncture were similar and localized in the state of comfort with both anesthetics. Girls showed more ocular response than boys. Subjective pain perception and physiological reactions showed no anesthetic- or sex-related differences, except for heart rate before and after the procedure which was significantly higher in girls. Conclusions: PLO 4% showed the same capacity as Hurricaine® in reducing pain response to needle puncture. Girls expressed more needle puncture-related pain than boys. The young children showed most prior comfort and less discomfort to the puncture than older children.

Effect of Zn, Cd and Cr on growth, water status and chlorophyll content of barley plants (H. vulgare L.)  [PDF]
águeda González, Valerio Chumillas, María del Carmen Lobo
Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.34069
Abstract: To evaluate the potential of barley for the phytoremediation of soils contaminated by metals, we conducted a growth chamber experiment with plants exposed to various concentrations of Zn, Cd and Cr. Growth parameters, chlorophyll content and chlorophyll fluorescence were measured at 15 and 29 days after treatment application, and the metal concentration in the aerial part of the plant, the root and the soil was also measured. In all cases, the amount of metal accumulated in the plant increased by increasing the concentration of the applied metal, and the roots accumulated more metal than did the aerial part of the plant. The amount of Cr found in the soil was significantly lower than that of Cd and Zn. The toxic effect of Zn and Cd on the plant was low, affecting growth only at the highest concentrations. For Zn and Cd at the concentrations used, the decrease in water content was 14% compared with the control and 26% for Cr. For plants treated with the highest metal concentrations, the most significant differences were found in chlorophyll content, which had the lowest values compared with the control (23% for Zn, and 42% for Cd and Cr), and in chlorophyll fluorescence (2% for Zn, 23% for Cd and 29% for Cr). These decreases occurred 29 days after applying the Zn and Cd treatments. In plants treated with Cr, the decrease occurred 15 days after treatment application. Under our experimental conditions, barley is more tolerant to Zn and Cd than to Cr.
