Accumulation of vehicles and irregular queues of two-wheeled vehicles at the time of red light are very influential on the performance of the intersection. To overcome the high proportion of motorbikes and the conflict problems that arise at the intersection, many alternative countermeasures have been made. One alternative that can be used is the Special Stop Room (RHK) lane. Which is expected to reduce queues and delays that are slowed down by vehicles, as well as by accidents that are passed. The purpose of this study was to analyze RHK activity, the percentage of RHK occupancy rate to capacity (Dc) RHK 1 in the morning period was 23%, during the afternoon period was 19%, in the afternoon period was 17% RHK 2 in the morning period was 38%, in the afternoon period it is 33%, in the afternoon period it is 27% RHK 3 in the morning period it is 46%, in the afternoon period it is 39%, in the afternoon period it is 32% based on the data obtained and from the results of the analysis carried out it can be ruled out that the level of effectiveness of RHK application on the line of Rs. Abdul Moeloek can be said to be less successful in determining the occupancy percentage, on average, less than 60%.

Fixed-site video cameras can be a powerful tool for studying marine animals in the sea without disturbing their behavior. Artificial light is required to use these cameras at night or in dark places such as inside animal dens. Red light is theoretically the best choice because the eyes of many marine animals are relatively insensitive to light above 600 nm wavelength, red light penetrates water much further than infrared, and many video cameras are highly sensitive to red light. This study found that video and red light can be used at night in the sea to study the behavior of spiny lobster, Panulirus argus, without significant effects. The shelter occupancy rate of tethered lobsters was similar in continuous red light as in the dark and red light did not attract or repel free-living lobsters. Red light did attract a small additional number of fish which were already nearby the lobster shelters and did not appear to disturb the lobsters. Loss of P. argus from octopus predation was similar in red light as in the dark. Six species of predators (two triggerfishes, an octopus, two snappers, and a moray eel) were recorded on videotape killing lobsters at shelters in the sea. Predation usually occurred outside the shelters. Other species scavenged on the lobster remains after they were killed. A variety of animals frequently cohabited with lobsters inside shelters for a few minutes to several days. The interactions of these animals with the lobsters rarely involved any strong aggression or defensive behavior.

The role of the circadian clock in the reproductive development of Syrian hamsters (Mesocricetus auratus was examined in wild type and circadian tau mutant hamsters reared from birth to 26 weeks of age under constant dim red light. Testis diameter and body weights were determined at weekly intervals in male hamsters from 4 weeks of age. In both genotypes, testicular development, subsequent regression and recrudescence exhibited a similar time course. The age at which animals displayed reproductive photosensitivity, as exhibited by testicular regression, was unrelated to circadian genotype (mean +/- SEM: 54 +/- 3 days for wild type and 59 +/- 5 days for tau mutants). In contrast, our studies revealed a significant impact of the mutation on somatic growth, such that tau mutants weighed 18% less than wild types at the end of the experiment. Our study reveals that the juvenile onset of reproductive photoperiodism in Syrian hamsters is not timed by the circadian system.

Selection Of

Spot colors are widely used in the food packaging industry. We wish to add a watermark signal within a spot color that is readable by a Point Of Sale (POS) barcode scanner which typically has red illumination. Some spot colors such as blue, black and green reflect very little red light and are difficult to modulate with a watermark at low visibility to a human observer. The visibility measurements that have been made with the Digimarc watermark enables the selection of a complementary color to the base color which can be detected by a POS barcode scanner but is imperceptible at normal viewing distance.
