Analisis Stabilitas Hasil Gabah Galur-galur Padi Melalui Pendekatan Parametrik Dan Nonparametrik

The failure of a genotype to perform relatively the same in different environments is defined as the interaction Genotype x Environment (G x E interaction). The existence of G x E is often causing breeders facing difficulty to select superior genotypes to be tested further. Efforts to quantify the interaction between the average yields of genotype with environment can be done by parametric and nonparametric approaches. Experiments were conducted at 16 sites in dry season of 2008 and 2009. A total of 14 rice genotypes were tested using randomized complete block design. Combined analyses of variances of 16 sites showed highly significant effects of locations, genotypes, and genotypes x locations. Parametric stability analysis using the coefficient of variability (CVi) showed 6 lines (BP1808-1F-25, BP1352-1G-KN, IR76510-24-3, BP1178-2F-26, OM 5240, OM 1490) were stable. Based on parametric analysis of variance stability (Sv), however only 3 lines namely BP1808-1F-25, S4616-PN-7-3, and IR76510-24-3 were stable. Cultivar superiority method of parametric stability showed that BP1808-1F-25, OM 5240 and OM 1490 were stable, while OM4495 was stable based on Nassar and Huehn nonparametric methods. Results of Spearman's correlation analysis showed that between CVi and Sv, and CVi and Pi were significantly correlated with r = 0.556, and r = 0.560, respectively. It indicated that those three stability parameters had equal strength for determining the stability of the lines or cultivars tested. Based on the three stability approaches BP1808-1F-25 was considered as stable line, while check cultivar Dodokan was unstable. Parametric stability was found more accurate than nonparametric ones, when assumption of the data distribution was fulfilled

Electrocardiographic and echocardiographic changes in patients with thyreotoxic cardiopathy

Thyreotoxic cardiopathy represents a cardiac pathology, caused by the toxic influence of the thyroid hormones on the myocardium. The aim of this study is to determine the frequency of cardiovascular changes in patients with thyreotoxic cardiopathy according to the ECG and EchoCG results. The study included 72 patients with Graves’ disease and thyreotoxic cardiopathy, whose medical records have been analyzed. Such criteria, as heart rate, heart rhythm disorders, left ventricle hypertrophy, repolarization abnormalities (in ECG), ejection fraction, valve disorders, heart cavities dilation, left ventricle hypertrophy, impaired cardiac relaxation and pulmonary hypertension (in EchoCG) have been taken into consideration. The results showed a high percentage of patients with ECG disturbances (75%) and a high percentage of patients with EchoCG disturbances (100%). According to the ECG results, the disturbances included heart rhythm disorders (51.4%), left ventricle hypertrophy (36.1%) and repolarization abnormalities (53.3%). The most frequent heart rhythm disorders determined by ECG have been atrial fibrillation (19.5%), sinus tachycardia (13.9%), Guis’ fascicular blocks (13.9%) and extrasystoles (9.7%). The EchoCG examination of the patients identified valve disorders (94.4%), the left ventricle hypertrophy (52.8%), the left ventricle impaired relaxation (11.1%), the simultaneous dilatation of three cavities of heart (left atrium, right ventricle and right atrium) (26.4%) and pulmonary hypertension (52.8%). However, the influence of concomitant cardiovascular diseases (25%) on the obtained results cannot be excluded, since the moment of their appearance is unknown

N=2 supergravity in five dimensions revisited

We construct matter-coupled N=2 supergravity in five dimensions, using the superconformal approach. For the matter sector we take an arbitrary number of vector-, tensor- and hyper-multiplets. By allowing off-diagonal vector-tensor couplings we find more general results than currently known in the literature. Our results provide the appropriate starting point for a systematic search for BPS solutions, and for applications of M-theory compactifications on Calabi-Yau manifolds with fluxes.Comment: 35 pages; v.2: A sign changed in a bilinear fermion term in (5.7

Hypermultiplets and hypercomplex geometry from 6 to 3 dimensions

The formulation of hypermultiplets that has been developed for 5-dimensional matter multiplets is by dimensional reductions translated into the appropriate spinor language for 6 and 4 dimensions. We also treat the theories without actions that have the geometrical structure of hypercomplex geometry. The latter is the generalization of hyper-Kaehler geometry that does not require a Hermitian metric and hence corresponds to field equations without action. The translation tables of this paper allow the direct application of superconformal tensor calculus for the hypermultiplets using the available Weyl multiplets in 6 and 4 dimensions. Furthermore, the hypermultiplets in 3 dimensions that result from reduction of vector multiplets in 4 dimensions are considered, leading to a superconformal formulation of the c-map and an expression for the main geometric quantities of the hyper-Kaehler manifolds in the image of this map.Comment: 18 pages; v2: several clarifications in text and formulae, version to appear in Class.Quantum Gravit

Wess-Zumino sigma models with non-Kahlerian geometry

Supersymmetry of the Wess-Zumino (N=1, D=4) multiplet allows field equations that determine a larger class of geometries than the familiar Kahler manifolds, in which covariantly holomorphic vectors rather than a scalar superpotential determine the forces. Indeed, relaxing the requirement that the field equations be derivable from an action leads to complex flat geometry. The Batalin-Vilkovisky formalism is used to show that if one requires that the field equations be derivable from an action, we once again recover the restriction to Kahler geometry, with forces derived from a scalar superpotential.Comment: 13 pages, Late

From de Sitter to de Sitter

We obtain D=6, N=(1,1) de Sitter supergravity from a hyperbolic reduction of the massive type IIA* theory. We construct a smooth cosmological solution in which the co-moving time runs from an infinite past, which is dS_4\times S^2, to an infinite future, which is a dS_6-type spacetime with the boundary R^3\times S^2. This provides an effective four-dimensional cosmological model with two compact extra dimensions forming an S^2. Interestingly enough, although the solution is time-dependent, it arises from a first-order system via a superpotential construction. We lift the solutions back to D=10, and in particular obtain two smooth embeddings of dS_4 in massive type IIA*, with the internal space being either H^4\times S^2 or an H^4 bundle over S^2. We also obtain the analogous D=5 and D=4 solutions. We show that there exist cosmological solutions that describe an expanding universe with the expansion rate significantly larger in the past than in the future.Comment: Latex three times, 22 pages, references adde

Scherk-Schwarz Reduction of D=5 Special and Quaternionic Geometry

We give the N=2 gauged supergravity interpretation of a generic D=4, N=2 theory as it comes from generalized Scherk-Schwarz reduction of D=5, N=2 (ungauged) supergravity. We focus on the geometric aspects of the D=4 data such as the general form of the scalar potential and masses in terms of the gauging of a ``flat group''. Higgs and super-Higgs mechanism are discussed in some detail.Comment: final version to be published on Class.Quant.Gra

Desain Penataan Daerah Di Provinsi Kalimantan Barat Tahun 2012 – 2025

Kemitraan and the Research institute of Universitas Tanjungpura have published a review of the “Design for Regional Arrangement in West Kalimantan Province 2012-2025.” This book explains the basic framework and design for the West Kalimantan regional arrangement 2012-2025, and also considers alternative designs for West Kalimantan based on spatial approaches. This book is intended to guide the Ministry of Home Affairs and development stakeholders, especially in the establishment of New Autonomous Regions (Daerah Otonom Baru/DOB). By providing proper analyses and criteria, it is hoped that the establishment of DOB will not occur just to fulfil the political interests of certain groups
