deadly thoroughfare. From 1993 to 2000‚ 72 pedestrians were killed crossing Queens Boulevard‚ an average of 10 persons per year with countless injuries nearly all pedestrians >60 years of age. It’s 12 lanes wide packed with heavy automobile traffic up to 70 thousand cars traveling on it daily. The distance to cross the street is 225 feet‚ for an elderly person this can be challenging or close to impossible when they only have 40 seconds to cross. New York City is very unique. It is one

height of Bracken (Pteridium aquilinum) from a light area and a dark area? Abstract: This investigation was designed to compare the height of Pteridium aquilinum in a light area and a dark area of Rushy Plains‚ Epping Forest and to establish if light intensity does have an effect on the growth of Pteridium aquilinum‚ commonly known as Bracken. From my research it was clear that the height of Bracken is affected by abiotic factors‚ other than light intensity‚ such as: soil moisture‚ soil temperature

Introduction The use of audible traffic lights at pedestrian crossing is to assist the vision less and disabled persons across any intersections. When reaching a pedestrian crossing‚ and knowing which direction to cross‚ the visionless and disabled persons must then know when to begin their crossing after hearing the audible traffic light’s signal sound. Since the traffic lights and the audible device are wired in parallel‚ as soon as the traffic light changed its color‚ the audible device

An Air Traffic Control Tower (Photo by Fred Mabonga) In many countries the pilot in command of the flight is the final authority for the safe operation of the aircraft. The pilot may‚ in an emergency situation‚ deviate from ATC instructions to the extent required to deal with the situation. This is carried as the pilot’s best professional consideration in view of the current emergency situation. In some instances it could be a split second decision in order to save the situation for the safety

the lateral displacement of a ray of light through a rectangular block of a transparent material. Aim: - To investigate the lateral displacement for different angles and how the displacement depends on the angle of incidence when a ray of light enters the Perspex block. Scientific Background: - Refraction occurs when the speed changes when the lights travels from one medium to another medium. If the light travels from a medium to a denser medium‚ the light slows down and consequently is refracted

Place the boxes in a designated area that gets plenty of sunlight during the day. Water each plant with a ¼ cup distilled water each day‚ watering at night so the plants are not exposed to light other than the light filtered through the cellophane. 6. Continue watering plants for four to six weeks. Note You can take pictures if you

your personal vehicle to reduce or even stop traffic related deaths and injuries? Over the years that figure continues to rise; now we’re doing something about it. Google have produced one of the several autonomous vehicles that exist today and they are testing them on public roads in busy cities. Some experts believe autonomous vehicles might reduce or even stop traffic related deaths and injuries. Since last year‚ according to Amanda Hoover‚ “Traffic related deaths have increased by 10.4 percent”
