Electric Dipole Moments in the Generic Supersymmetric Standard Model

The generic supersymmetric standard model is a model built from a supersymmetrized standard model field spectrum the gauge symmetries only. The popular minimal supersymmetric standard model differs from the generic version in having R-parity imposed by hand. We review an efficient formulation of the model and some of the recently obtained interesting phenomenological features, focusing on one-loop contributions to fermion electric dipole moments.Comment: 1+7 pages Revtex 3 figures incoporated; talk at NANP'0

"Are Black Holes in Brans-Dicke Theory precisely the same as in General Relativity?"

We study a three-parameters family of solutions of the Brans-Dicke field equations. They are static and spherically symmetric. We find the range of parameters for which this solution represents a black hole different from the Schwarzschild one. We find a subfamily of solutions which agrees with experiments and observations in the solar system. We discuss some astrophysical applications and the consequences on the "no hair" theorems for black holes.Comment: 13pages, Plain Te

On a possible solution for the Polonyi problem in string cosmology

We establish the main features of homogeneous and isotropic dilaton, metric and Yang-Mills configurations in a cosmological framework. We identify a new energy exchange term between the dilaton and the Yang-Mills field which may lead to a possible solution to the Polonyi problem in 4-dimensional string models.Comment: plain Tex, 4 pages.

Constraints on Supergravity Chaotic Inflationary Models

We discuss, in the context of $N=1$ hidden sector non-minimal supergravity chaotic inflationary models, constraints on the parameters of a polynomial superpotential resulting from existing bounds on the reheating temperature and on the amplitude of the primordial energy density fluctuations as inferred from COBE. We present a specific two-parameter chaotic inflationary model which satisfies these constraints and discuss a possible scenario for adequate baryon asymmetry generation.Comment: Latex file, 10 pages; important changes and references adde

Comparative Evaluation of Nutritive Value of Okro (Abelmoschus esculentus) and Bush Mango (Irvingia gabonensis) Fruits Grown in Nasarawa State, Nigeria

The proximate, mineral and amino acid compositions of okro (Abelmoschus esculentus) pod and bush mango (Irvingia gabonensis) seed were determined using standard analytical techniques. Moisture, ash, crude fat, crude fibre, protein and carbohydrate (by difference) contents (%) of A. esculentus and I. gabonensis were: 25.9 and 2.1, 9.0 and 11.5, 17.2 and 62.0, 4.3 and 0.9, 21.8 and 7.4, and 21.8 and 26.1, respectively. The most abundant minerals were Ca (170.6 and 431.5 mg/100g sample), K (108.5 and 161.0 mg/100g), Mg (83.6 and 171.1 mg/100g) and Na (88.0 and 113.5 mg/100g), respectively. Generally, the two samples were found to be good sources of essential minerals while harmful metals such as Pb and Cd were not at detection limit of AAS. The levels of Na/K and Ca/P ratios were desirable compared with the recommended values. The amino acid profile revealed that samples of A. esculentus and I. gabonensis contained nutritionally useful quantities of most of the essential amino acids with total essential amino acids (TEAA) of 35.4 and 38.1 g/100g crude protein or 40.6 and 47.8% of the total amino acid (TAA), respectively while the limiting amino acids (LAA) were Val and Thr. The calculated isoelectric points (pI) and predicted protein efficiency ratios (P–PER) were 5.1 and 4.8, 2.5 and 4.1 for A. esculentus and I. gabonensis, respectively. However, dietary formula based on these fruits may require amino acids supplementation. Keywords: Abelmoschus esculentus, Irvingia gabonensis, nutritional composition

Analytical Modelling of Human Arm Locomotion during Dance as a Dynamical Multiple Pendulum System

During dance human arms move. The movement of the arms, to a large extent, determines how good a dance is. This paper attempts to model the locomotion of human arm, analytically, during a dance as a dynamical multiple pendulum system with three segments. The system is analyzed by considering some instances during the dance. The three angles the three segments make with the vertical are considered. The Euler-Lagrange equation is used in obtaining the equation of Motion. The resulted second order differential equation is solved analytically. Simulation results are presented. They are consistent with the ones in literature. Specifically the angular displacement values of the three segments are directly proportional to their respective angular acceleration. However, the novelty of this work is in the full analytical approach to 3-pendulum system and its application to danc
