    Maize is the second basic food need after rice that is potential and has high economic value in increasing income of farmers and food diversification program. White maize, in particular, is an alternative staple food in Grobogan Regency. The superior variety is a component of technology that plays a prominent role to increase productivity, disease resistant, and environmentally suitable (specific location). The aim of the study was to determine the influential factors in the adoption of superior variety of white maize in order to achieve transfer of technology. The study was carried out in three villages of Grobogan Regency, Central Java: namely Sumber Jatipohon, Godan, and Karangasem. The locations were determined with purposive sampling and the number of respondents interviewed was 120 farmers (40 farmers in each village) between September-December 2015. Analyses of the data were descriptively and quantitatively using percentages, charts and tables with logistic regression. The results of this study showed that the interest of farmers to adopt new superior variety of white maize was quite good around 66.7 percent. Farmers' interest toward superior variety may be considered high. While factors significantly influencing the adoption included income, knowledge or information on technology, agriculture extension support, pest, and availability of seeds. On the other hand, factors which were not significantly affecting the adoption included age, formal education, farmers' experience, and land size

    This study aims to identify the literature that explores health coaching interventions in improving Heart Failure (HF) self-care management, focusing on the total duration and type of health coaching media. The research method uses literature reviews by tracing publications between 2017-2020, the Cochrane database, PubMed, ScienceDirect, ProQuest, and Garuda. The results identified five health coaching studies according to inclusion criteria and resulted in significant improvements in HF self-care management, including symptom reporting, increased physical activity, low-salt diet, fluid and drug intake, self-efficacy, adherence to measuring body weight and blood pressure, and changes. Lifestyle, even though there are differences in the health training methods used. In conclusion, the duration and different media from each study did not significantly influence improving HF self-care management.   Keywords: Heart Failure, Self-Care Management, Health Developmen

    Polygon model from first order gravity

    Full text link
    The gauge fixed polygon model of 2+1 gravity with zero cosmological constant and arbitrary number of spinless point particles is reconstructed from the first order formalism of the theory in terms of the triad and the spin connection. The induced symplectic structure is calculated and shown to agree with the canonical one in terms of the variables.Comment: 20 pages, presentation improved, typos correcte

    Timelike surfaces in Lorentz covariant loop gravity and spin foam models

    Full text link
    We construct a canonical formulation of general relativity for the case of a timelike foliation of spacetime. The formulation possesses explicit covariance with respect to Lorentz transformations in the tangent space. Applying the loop approach to quantize the theory we derive the spectrum of the area operator of a two-dimensional surface. Its different branches are naturally associated to spacelike and timelike surfaces. The results are compared with the predictions of Lorentzian spin foam models. A restriction of the representations labeling spin networks leads to perfect agreement between the states as well as the area spectra in the two approaches.Comment: a wrong sign corrected in equation (65

    Turing Instability in a Boundary-fed System

    The formation of localized structures in the chlorine dioxide-idodine-malonic acid (CDIMA) reaction-diffusion system is investigated numerically using a realistic model of this system. We analyze the one-dimensional patterns formed along the gradients imposed by boundary feeds, and study their linear stability to symmetry-breaking perturbations (Turing instability) in the plane transverse to these gradients. We establish that an often-invoked simple local linear analysis which neglects longitudinal diffusion is inappropriate for predicting the linear stability of these patterns. Using a fully nonuniform analysis, we investigate the structure of the patterns formed along the gradients and their stability to transverse Turing pattern formation as a function of the values of two control parameters: the malonic acid feed concentration and the size of the reactor in the dimension along the gradients. The results from this investigation are compared with existing experiments.Comment: 41 pages, 18 figures, to be published in Physical Review
