Adult emergence (eclosion) of fruit flies Drosophila melanogaster under constant laboratory conditions follows a circadian pattern with bouts of eclosion recurring at approximately 24 h intervals. Under periodic light:dark (LD) cycles, adults emerge only during a specific time of the day followed by little or no emergence for the rest of the day. This(More)
Although, circadian clocks are believed to be involved in the regulation of life-history traits such as pre-adult development time and lifespan in fruit flies Drosophila melanogaster, there is very little unequivocal evidence either to support or refute this. Here we report the results of a long-term study aimed at examining the role of circadian clocks in(More)
INTRODUCTION To evaluate the efficacy of NiTi mechanical rotary instrumentation and Hedstrom file for gutta-percha/sealer removal computed tomography (CT) was utilized in vitro. MATERIALS AND METHODS Thirty extracted human single rooted teeth, each with a single canal were selected. The samples were decoronated with a double faced diamond disk to have(More)
Elemental mercury poisoning most commonly occurs through vapor inhalation as mercury is well absorbed through the lungs. Administering subcutaneous and intravenous elemental mercury is very uncommon but with only a few isolated case reports in the literature. We present an unusual case of elemental mercury poisoning in a 20-year-old young male who presented(More)

Keywords: Solar PV system mc-Si solar PV module a-Si solar PV module Performance ratio a b s t r a c t A study is conducted for solar PV energy generation from two grid-connected installations (mc-Si and a-Si power plants) located at the same place in Gujarat, Western India. Data-sets on electricity production were collected over entire year and compared(More)
Insects including the fruit fly Drosophila melanogaster are under intense pressure to develop rapidly because they inhabit ephemeral habitats. We have previously shown that when selection for faster development was artificially imposed on D. melanogaster in the laboratory, reduction of pre-adult development time and shortening of the clock period occurs,(More)
Age-related changes in circadian rhythms have been studied in several model organisms including fruit flies Drosophila melanogaster. Although a general trend of period (τ) lengthening, reduction in rhythm strength and eventual arrhythmicity with increasing age has been reported, age-related changes in circadian rhythms have seldom been examined in the light(More)
Circadian clocks have been postulated to regulate development time in several species of insects including fruit flies Drosophila melanogaster. Previously we have reported that selection for faster pre-adult development reduces development time (by ~19 h or ~11%) and clock period (by ~0.5 h), suggesting a role of circadian clocks in the regulation of(More)
BACKGROUND To describe, a yet non-documented complication of GDI surgery (glaucoma drainage incision surgery)--anterior to posterior segment migration of Ahmed Glaucoma Valve (AGV) tube. CASE PRESENTATION We report a young 9 year old boy, diagnosed with refractory glaucoma with Reiger anomaly. History included of poor vision in both eyes, left more than(More)
Distance measures are part and parcel of many computer vision algorithms. The underlying assumption in all existing distance measures is that feature elements are independent and identically distributed. However , in real-world settings, data generally originate from heterogeneous sources even if they do possess a common data-generating mechanism. Since(More)
