Chromosome numbers of one species Eranthemum (E. macrophyllum Wall. ex Nees) and five Strobilanthes [S. affinis (Griff.) Terao J. R. I. Wood et Benett., S. biocullata Y. F. Deng & Wood, dimorphotricha Hance, heteroclita D. Fang H. Lo pseudocollina K. He Qin] in the family Acanthaceae from China have been reported for first time. The chromosome were determined as 2n=4x=44 E. macrophyllum, 2n=2x=...

The purpose of this paper is twofold. First we derive theoretically, using appropriate transformation on x(n), the closed-form solution of the nonlinear difference equation x(n+1) = 1/(±1 + x(n)), n ∈ N_0. The form of solution of this equation, however, was first obtained in [10] but through induction principle. Then, with the solution of the above equation at hand, we prove a case ...

Malaria control projects based on the introduction and spread of transgenes into mosquito populations depend on the extent of isolation between those populations. On the basis of the distribution of paracentric inversions, Anopheles gambiae has been subdivided into five subspecific chromosomal forms. Estimating gene flow between and within these forms of An. gambiae presents a number of challen...

Fetal hemoglobin (Hb F) production in sickle cell (SS) disease and in normal individuals varies over a 20-fold range and is under genetic control. Previous studies suggested that variant Hb F levels might be controlled by genetic loci separate from the beta-globin complex on chromosome 11. Using microscopic radial immunodiffusion and flow cytometric immunofluorescent assays to determine the per...

We provide a rigorous lower bound for the ionization probability of a Rydberg atom under the perturbation by a time-dependent electric eld in the form of an ultrashort pulse idealized as a Dirac-function. This estimate is of the form 1 ? O(F ?4 0) for large values of the electric eld F 0. For the hydrogen atom we also prove the scaling behavior F 0 n ?1 , predicted recently by Reinhold et al. P...

the fao penman - monteith (f-p-m) method is now broadly accepted as the standard for estimating the reference evapotranspiration (et0). the method is also now used for evaluating the temperature-based [blaney-criddle (b-c) and hargreaves-samani (h-s)] and radiation-based [jensen-haise (j-h) and turc (tc)] methods. the objective was to compare the et0 estimated by the b-c, h-s, j-h, tc methods w...

Two informative chicken F(2) populations based on crosses between a broiler breeder male line and dams from genetically distinct, highly inbred (>99%) chicken lines, the Leghorn G-B2 and Fayoumi M15.2, have been used for genome-wide linkage and QTL analysis. Phenotypic data on 12 body composition traits (breast muscle weight, breast muscle weight percentage, abdominal fat weight, abdominal fat ...
