The white-ivory somatic mutation test of Drosophila melanogaster is based on the reversion of the X-linked eye colour recessive mutation white-ivory to wild-type. Although the exact mechanism of white-ivory reversion is not quite understood, it has been suggested that such reversion, both in somatic and germ-line cells, could be due to the precise excision of the tandemly duplicated 2.96 kb DNA...

HS0907+1902 was recently discovered to be one of a handful of deeply eclipsing dwarf novae with periods longward of the 2 – 3 hr ‘gap’. This paper presents orbit-resolved spectra and time series photometry of an eclipse. The apparent velocity amplitude of the M-dwarf secondary is K2 = 297 ± 15 km s . The phase of the radial velocities of the Hα emission line wings agrees accurately (for once) w...

Dynamic Partial Reconfiguration (DPR) of FPGAs presents many opportunities for application design flexibility, enabling tasks to dynamically swap in and out of the FPGA without entire system interruption. In this paper, we will implement a line follower robot for the white line as well as for black line; both these modules will be programmed in VHDL. The robot will dynamically reconfigure the F...

OBJECTIVE The aim of this study was to evaluate the value of lung ultrasound in the diagnosis of respiratory distress syndrome (RDS) in newborn infants. METHODS From March 2012 to May 2013, 100 newborn infants were divided into two groups: RDS group (50 cases) and control group (50 cases). According to the findings of chest x-ray, there were 10 cases of grade II RDS, 15 grade III cases, and 2...

objective: the usage of pesticides has increased during the recent years. one the other hand, presence of harmful pesticides residue in rice and other food has caused a great concern among the consumers. therefore, it is important to develop some pragmatic procedures to increase the food safety along with the reduction in consumption of pesticide residues. methods: a gas chromatograph with elec...
