Artificial lighting systems are transitioning from incandescent to compact fluorescent lamp (CFL) and light-emitting diode (LED) bulbs in response to the U.S. Energy Independence and Security Act and the EU Ecodesign Directive, which leads to energy savings and reduced greenhouse gas emissions. Although CFLs and LEDs are more energy-efficient than incandescent bulbs, they require more metal-con...

In the so called lightbulb process, on days r = 1, . . . ,n, out of n lightbulbs, all initially off, exactly r bulbs selected uniformly and independent of the past have their status changed from off to on, or vice versa. With Wn the number of bulbs on at the terminal time n and Cn a suitable clubbed binomial distribution, dTV(Wn,Cn)≤ 2.7314 √ ne−(n+1)/3 for all n≥ 1. The result is shown using S...

In this paper, we give a brief overview of the geometry of the Mandelbrot set. We show how to distinguish each of the principal bulbs hanging off the main cardioid of this set by counting the spokes of the antennas attached to each bulb. We also use these antennas to attach a fraction to each such bulb, and this then indicates how these bulbs are arranged around the boundary of the main cardioid.

Malformin was identified, by its biological activity and chromatography, in acetone extracts of the outer scales of onion bulbs infected with Aspergillus niger. Malformin was not detected in tissue underlying the infected areas or in the central portions of the bulbs, nor was malformein liberated from extracts or extracted tissues after reduction with zinc in acetic acid. This is the first repo...

The effect of storage at two temperatures (5±1 and 25±1 °C and 60-70±5% RH for both temperatures) on marketability and quality features of dry bulbs of local landrace "Vatikiotiko", "Sivan F1", "Red Cross F1" and "Creamgold" was examined. During storage measurements for fresh and dry weight of bulbs, tunic and flesh color, bulb firmness, nutritional value and mineral composition were taken at r...

OBJECTIVE Recent studies show that free radicals are important mediators of hepatic injury induced by carbon tetrachloride. Allium (A.) paradoxum showed antioxidant and antihemolytic activities. This work was conduct to determine the possible protective effect of this plant against hepatotoxicity. MATERIALS AND METHODS Subcutaneous injection of 3 ml/kg carbon tetrachloride diluted in olive oi...

Leucojum aestivum (summer snowflake) is a plant species used for the extraction of galanthamine, an acetylcholinesterase inhibitor for the treatment of Alzheimer's disease. Extracts from bulbs collected from 18 Bulgarian populations and from shoot-clumps obtained in vitro from 8 different populations showed variations in their alkaloid composition. Nineteen alkaloids were detected in the studie...

In recent time, the power quality has attracted a lot of attention due to extensive emphasis by power utility on the power system efficiency and end users awareness of power quality issues. This has occurred mainly due to the sensitivity of the modern equipment and the deregulation of the power distribution. In addition, there are usually massive losses both to power utility and end users due t...

Looking up – you realize that one of the twelve light bulbs of your living room chandelier has to be replaced. You turn electricity off, move a table to the center of the room, put a chair on top of the table and, new bulb in hand, you climb up on top of the chair. As you reach the chandelier, you notice that. . . all bulbs look alike and that you have forgotten which bulb needed to be changed....

This research aimed to determine the effect of several varieties on different populations growth and yield shallot ( Allium ascalonicum L.) from botanical seeds (True Shallot Seed). was an experimental conducted August October 2021 in integrated farming system area, Serang, Banten. laid out a factorial randomized block design (RCBD) consisting two factors. The first factor differences consist 3...
