Population genetics is a branch of biology which studies about the gene composition from population and the change of the gene composition is effect from some factors. One of them is lethal gene factor. The change of gene composition will influence the genotype probabilities in the population. In this paper discussed about determining the genotype for the probability of the n-th offspring genotypes in dihybrid mating by observing linkage between the two loci. The mating occurred randomly and without concern ethics in mating. This research was done by making mathematics model to determine allele pair, using difference equation, then from this model will be determined genotypes probability. The result show that the mating happened normally had the same genotype probability of each generation, meanwhile in abnormal mating, the genotype probability whose had lethal gene would decrease and the genotype probability whose did not have lethal gene would increase in each generation.Keywords : Difference equation, dihybrid mating, lethal gene, population genetics, probability

Analysis of Blood Flow in Arterial Stenosis Using Casson and Power-Law Fluid Model Riri Jonuarti
Jurnal ILMU DASAR Vol 14 No 2 (2013)
Publisher : Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Jember

Simulation of blood flow behaviour in the arteries and in arterial stenosis has been made and will be discussed in this paper. This simulation uses pulsatile flow and blood flow in artery without stenosis is considered as a dynamic fluid, compressed and condensed. Whereas, in the case of arterial stenosis has been used Casson and Power-law fluid models. In the arteries without stenosis, blood flow velocity profiles show the same pattern for each Womersley number, but with different speed value. In the case of arterial stenosis, blood flow rate decreases with increasing stenosis position away from axis of blood vessels. Resistances to flow are increases with increasing the size (height and length) of stenosis, both for the Casson and Power-law fluid models. If resistance to flow increases, it is more difficult for the blood to pass through an artery, result the flow decreases and heart has to work harder to maintain adequate circulation.Keywords : Artery, blood flow, power-law fluid, Casson fluid, stenosis

A few numerical methods that usually used to solve neutron transport equation in nuclear reactor are SN dan PN method, Monte Carlo, Collision Probability and Methods of Characteristics . First two methods have been developed using diffusion approach, and last three methods suitable are applicated for transport approximation. Those of three methods have important role in the desain of nuclear reactors. In addition to follow the development of advanced reactor designs, the three methods were chosen because they do not use diffusion approach these are more accurate methods, as well as less need considerable computer memory. Of all the existing methods, the CP method has several advantages among the others. Keywords : Neutron transport, SN, PN, CP, MOC, MC

Development of biocomposite materials based on natural fibers and environmentally friendly resins to replace composite materials made from plastic and synthetic fibers give the consideration that the biocomposite materials are environmentally friendly materials. In this paper, we discuss the synthesis and characterization of biocomposite materials using a combination of thin sheets of bamboo reinforcement and resin sengon and poly lactic acid (PLA). As controls were also carried out the synthesis and characterization of biocomposite material with a thin layer of reinforcement only sengon bamboo and wood. Characterization of tensile strength and modulus of elasticity of the material is done by using the Tensile Test Machine ASTM D 638. In the mean time, biodegradability of materials are observed made by the method of burial for 1-4 weeks. Tensile test results show that the biocomposite material reinforced with a thin sheet bamboo has a tensile strength and modulus of elasticity greater than that of the other biocomposite materials produced in this study. Meanwhile, biocomposite materials with thin layers of wood sengon reinforced easily biodegradable (dG = 13.21 ± 0.59)%, compared to a biocomposite material with a thin layer of bamboo reinforcement (dG = 10.69 ± 0.79)%. From these results it can be concluded that the composite material with a thin layer of bamboo boosters are more likely to be applied to replace metallic materials.Keywords: Biocomposites, tensile strength, elastic modulus, biodegradability, bamboo and sengon wood thin layer.

Publisher : Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Jember

Ensemble Kalman Filter (EnKF) can be applied for linear or nonlinear models. This paper is aimed to estimate the logistic growth of population models using EnKF. The estimation will be compared with the analytical solution. We assume that we can find the analytical solution of the models. The models is in the specific form i.e comparison between the population growth rate and the amount of population is in the parabolic form. The good estimation will be attained by choosing 100 as size of ensembles in EnKF. The result of estimation really so closed to the analytical solution. Keywords : Analytical solution, EnKF, ensemble
