...Chromosome Crossing Over Do you ever wonder why two people besides identical twins are not alike? Our genes determine most of our physical characteristics, the exact combination of genes we inherit, and thus our physical traits is in part due to the process our chromosomes undergo, known as genetic recombination. Biology online states, that during meiosis, when homologous chromosomes are paired together, there are points along the chromosomes that make contact with the other pair. This point of contact is chiasmata, and can allow the exchange of genetic information between chromosomes. This further increases genetic variation. Recombination can occur between any two genes on a chromosome. The amount of crossing over is a function of how close the genes are to each other on the chromosome. If two genes are far apart, at opposite ends of the chromosome, more crossing over is possible. If the genes are closer together fewer crossing over is possible (McClean, 1998). Two types of gametes are possible when following genes on the same chromosomes. If crossing over does not occur, the products are parental gametes. If crossing over occurs, the products are recombinant gametes. The allelic composition of parental and recombinant gametes depends upon whether the original cross involved genes in coupling or repulsion phase. It is easy to determine which gametes are recombinant because they are found in the lowest frequency (McClean, 1998). In the 1930’s Harriet Creighton and Barbara...

...The countryside was lush, sparkling with a plum blue serene from the early morning sunrise. Atop the highest of the Vilorian Mountains, the city of Astral stood silent against the ringing of silver trumpets from the north highlands. The travelers crossing the last of the mountains rocky crossings took in the scene from under the fruits of a Bombaly tree, standing colossal at one hundred meters in height. Petty fruits the size of a child’s fist lay strewn about under its goliath canopy, dripping with ruby red nectar. The morning wind was crisp and slightly harsh, a sign to all that the winter seasons were coming with quickness. The trail leading up to the city was a four day expedition from the coast, and it had been a taxing journey for all in company. From where he lingered on the edge of the vast mountain Cyril looked down upon the Port of Themme, twenty leagues off. The brilliant light of the day lit up the ocean and surrounded all with a dazzling view of the great maritime reefs that stretched as far as the eye could see. The vastness of the blue ocean always seemed to enlighten Cyril when it stared up at him from the deep, and like always, he treasured the view for a fleeting moment. But with great beauty comes great sorrow, and at that moment the reality of the daunting mission he was on got the better of him, turning his gaze southwards to his...

...for turtle crossings By Sarah Zelinski | 1 | It’s really too bad that turtles can’t read. | 2 | If they did, it would make saving them so much easier. When people create an ecopassage1 so the reptiles can safely cross a road by going underneath or over it, they could let the animals know with little signs saying “Don’t become roadkill! Safe crossing, left 20 meters.” | 3 | Instead, we have to rely on fencing to keep the turtles and snakes off roads, which is a good idea because 98 percent or more of turtles are killed in their first attempt at a road crossing. But the reliance on fences may be a problem, a new study shows. When there aren’t effective fences to keep the reptiles out, they don’t use the ecopassages, James Baxter-Gilbert of Laurentian University in Sudbury, Ontario, and colleagues report March 25 in PLOS ONE. | 4 | The study looked at the effectiveness of a series of ecopassages built along a 13-kilometer stretch of Highway 69/40 near Burwash, Ontario, near Lake Huron, a region with high reptile biodiversity. The passages ran beneath the highway and were paired with fencing along the road. The researchers looked at reptile activity along the roadway before and after the project was constructed, and also used another stretch of highway, near the Magnetawan First Nation, as a comparison. | 5 | They surveyed the roadside and put up cameras in the ecopassages to see what kind of animals used the crossings. They captured...

...SIGNALIZATION Alf Badge., P.E. Senior Engineer Post-Buckley-Schuh-Jernigan, Inc Charlotte, North Carolina Charles V. Zegeer, P.E. Associate Director of Roadway Studies Highway Safety Research Center University of North Carolina Chapel Hill, North Carolina FIGURE 5-1 Pedestrian signal displays.' Traffic Signals Traffic signals are intended to assign the right-of-way to vehicular and pedestrian traffic. When installed appropriately, traffic signals can provide many benefits, including the interruption of heavy volumes of motor vehicles where there are insufficient gaps in motor vehicle traffic for pedestrians to cross safely at intersections or midblock locations. Unwarranted or improperly used traffic sig-nals can cause excessive delay for pedestrians and motor vehicles, signal disobedience, and an increase in certain accident types. Even where warranted, traffic signal installations commonly result fn an increase in rear-end and total accidents, with a corresponding reduction in more severe right-angle acci-dents. The effect of traffic signal installations on pedestrian accidents is not well known, but different locational characteristics of the sites are important factors in the accident experience at signals.° While many traffic signals include only the green, yellow, and red signal faces, a variety of signal lens faces may be used, depending on needed signal phasing. Studies have suggested, however, that highly-com-plex, multiphase signals often result in con-fusion...

...Intelligent Traffic Control and Pedestrian Crossing System C.H.W. Jayawardane Faculty of Information Technology, University of Moratuwa, Sri Lanka Abstract - This paper proposes an intelligent traffic light and pedestrian crossing system that can be used to address traffic congestion in a four way junction. The approach is primarily focused on creating a system which dynamically responds to traffic conditions and road users. The system makes use of sensors to detect the presence of a vehicle. A number of these sensors placed accordingly are used to identify the number of vehicles in a particular lane. Based on this input, which is the vehicle line length in a lane the traffic control algorithm implemented in our system takes the necessary decisions. This algorithm determines the lane that should be given the most priority and up to what amount of time. This feature allows maximum efficiency in controlling the flow of traffic. The pedestrian crossing system uses image processing technology to identify the number of waiting pedestrians. When this number reaches a defined value they are given the chance to cross the road. Else after a maximum time limit is exceeded and the required number has not yet gathered the remaining will be given a chance to navigate safely across the road. A count down timer display is used to show the remaining time the pedestrians have. It can be illustrated that the proposed system provides a cost efficient and environmentally friendly method to all...

...GRAPHICS Road safety Everyday many people are involved in road accidents. Some are killed. Many more are injured or maimed. So it is important for us to learn to use the roads properly and safely. No sane person would like to be involved in an accident. As the roads are very busy nowadays, we should be very careful when crossing one. It is safer to use a pedestrian crossing or an overhead bridge whenever one is available. Never cross a road by dashing across it. That is inviting trouble. If there are no crossings, then we must look carefully right and left and cross only when it is safe to do so. Some of us take the bus to school. It is important that we do not try to get on or off a bus while it is still moving. I tried to get on a moving bus once. It dragged me a short distance and nearly ran over me. I was lucky to escape with only some scratches on my legs. Also we must not fool around while in the bus. A suddenly lurch can send us knocking our heads against something hard. Using a bicycle can be dangerous too. We must pay attention on the road and never cycle too far out to the middle of the road. We must obey all traffic rules. Also we must make sure our bicycles are in good condition with working brakes, lights etc. These are some things we can do to avoid accidents. However there is no guarantee that we will never be involved in one. The important thing is to stay alert at all times while using the roads. We must know what is happening around us. In that way we can...

...performance. It accomplishes this through the use of a combination of data compression, content and object-caching, data deduplication and protocol optimization. A WAN optimization appliance works in conjunction with the available bandwidth at a location. The host site would have an appliance that would build ‘acceleration tunnels’ to each of the appliances located at the remote sites. The appliances at the remote sites would be sized based upon the number of users and the available bandwidth at that location. This solution has a number of advantages. It is a very cost-effective approach. Higher bandwidth circuits in remote areas tend to be expensive. The purchase of network appliances are normally a capital expenditure that can be amortized over the life of the product. This timeframe is normally 3 to 5 years. On the other hand, the addition of larger circuits is an operational expenditure that incurs a higher recurring cost on a monthly basis. Secondly, these appliances are transparent to the end user. They do not require additional software on the users’ computers, or require any special setup on a per-user basis. NHS would very likely fall into the Early Adopters category in the Technological Acceptance Curve for this solution...

...there will be absolute chaos and confusion on the road, and no one will be able to move about. This chaos would lead not only to delays in movements but would also lead to struggles and even accidents. When, for example we are supposed to cross the road from the zebra crossing, we must make sure that we do so, for, if we cross from elsewhere, there is a chance that we meet with an accident. If we jump a red light we are putting ourselves to danger and are inviting trouble with the possibility of an accident. Thus, rules must be followed for maintaining discipline on the roads, and above all for our own safety. It is in our own interest that, when on the road, we follow the road traffic rules to the last word. The rules are there to keep us safe, and following them is in our own interest. When we break the rules we are inviting trouble to ourselves and doing no harm to any one else. The traffic rules in India are as strict as they are anywhere else in the world. However, the difference between the rules outside India and the rules in India is basically just one. That is the rules in foreign countries are followed, and here in India they are broken day in and day out. Besides having more or less the same rules, over here we Indians have an instinct to break all laws and rules. That instinct is so very vivid on the...

...Hilario Ramos Ms.Kemp Eng 009 Are Solar Roadways the future? In the beginning Scott and Julie Brusaw became open on the subject for creating solar-powered LED roadways, they have encountered an endless amount of doubt and even outright aggression. The reaction was obviously expected given how new this sort of technology is. Not only is it new, but it would quite difficult to execute the dream of electrifying roads and highways with reinforced solar panels. Some questioned question if whether or not solar roadways are even necessary. However, the most important company that governs American roads -- was willing to at least give the idea a shot. Although the idea of solar roadways does sound amazing has many obvious potholes, but its benefits are vastly in numbers. The major advantages of the solar roadway is that it uses its utilities as a refurbishing like source of to create electricity. It has the possibility to diminish dependence on sources of energy like coal and other fuels. Also, the durability of a solar panel last about 20 years, so much better than your common asphalt roads, which last about 12 years. If the time ever occurred of an environmental disaster or military problem occurred, like an emergency, solar roadways are there to lend their power which will most likely be needed. Solar power can be easily renewed, it does not need any outside connection to any sort of power source. Another great perk is that they do not need the development of possibly sensitive...

...Safe Streets Act of 2014 Kaplan University At first glance, Charleston S.C. is an idyllic city. It is an old town, with cobbled streets and narrow antiquated sidewalks; on closer inspection it will reveal its hidden dangers. These quaint and roughhewn areas are actually injuring and killing people at an alarming rate. The state was ranked fourth in the nation for its pedestrian danger index; Charleston’s statistics were directly at the top. (Dangerous by Design S.C., 2014) The need for safer sidewalks and streets for all pedestrians should be a maximum priority, and there is a plan in place to help to do this. The Safe Street Act is a law yet to be enacted, but is gaining in popularity in the Senate. The act sets the blueprint which will make a difference in the way streets and sidewalks will be built from now on. It will support the safety and convenience of all it’s users, including pedestrians, bicyclists, public transit users and drivers. It will reconstruct and rehabilitate the existing problem areas and will not allow building in any more dangerous areas. The Safe Streets Act of 2014 will protect our citizens especially our seniors from many of the perils of living in Charleston. The bill, introduced to the Senate on February 6th, 2014 by senators Brian Schatz and Mark Begich is a comprehensive one. It creates incentives for federal transportation agencies to design safe streets for all; this would also include people of all ages and disabilities. Two-thirds...
