ALTHOUGH attempts at establishing the human chromosome number dates from early in this century, it was not until 1957 when improvements in techniques became available that human cytogenetics became established as a laboratory discipline. Since 1959, many clinical disorders ranging from abnormalities of sexual, physical and intellectual development, pregnancy wastage, leukaemia and tumours, have...

The problem considered is the non-preemptive scheduling of independent jobs that consume a resource (which non-renewable and replenished regularly) on parallel uniformly related machines. input defines speed machines, size jobs, quantity required by quantities, replenishment dates resource. Every job can start processing only after allocated to job. objective function generalization makespan mi...

Drought is a stochastic natural hazard that is instigated by intense and persistent shortage of precipitation. Following an initial meteorological phenomenon, subsequent impacts are realized on agriculture and hydrology. Among the natural hazards, droughts possess certain unique features; in addition to delayed effects, droughts vary by multiple dynamic dimensions including severity and duratio...

recombinant human erythropoietin (rh-epo) is known to accelerate erythropoiesis in preterm infants. the purpose of this study was to compare the effectiveness of early treatment with two doses of rh-epo (high vs. low dose) in the management of anemia of prematurity. twenty preterm infants with hematocrit (hct) < 30% when infant’s age was between 2 to 3 weeks after birth or hct <25% when infant’...

In this paper, two new quadrilateral elements are formulated to solve plane problems. Low sensitivity to geometric distortion, no parasitic shear error, rotational invariance, and satisfying the Felippa pure bending test are characteristics of these suggested elements. One proposed element is formulated by establishing equilibrium equations for the second-order strain field. The other suggested...

In this paper we contribute to the general philosophical‎ ‎question as to whether empirical testing can ever prove a physical law.‎ ‎Problems that lead to this question arise under several contexts‎, ‎and the ‎matter has been addressed by the likes of Bayes and Laplace‎. ‎After pointing‎ ‎out that a Bayesian approach is the proper way to address this problem‎, ‎we‎ ‎show that the answ...

Stator flux oriented vector control of induction motor (IM) drives for speed sensorless control has several advantages. But the application of a pure integrator for the flux estimation is difficult due to the presence of measurement noise and dc offset. To overcome these problems, some have used a programmable cascaded low pass filter (PCLPF). In this paper, it is shown that some problems still...
