Simulation of pedestrian counter flow with conflicting preference using a lattice-based simulation model

Pedestrian counter flows widely exist in public pedestrian facilities such as corridors, sidewalks, signalized crossings and so on. There is one specific flow in real life, namely counter flow with conflicting walking preference which often occurs in the case of presence of one-sidedly asymmetry due to shadows, light, snow and so on. It is often overlooked in practice and the related studies are still limited. In this study, to better understand the flow dynamics of pedestrian flow with various walking preference, a simple lattice-based model was proposed in which position exchange and walking preference were simultaneously considered. Specifically, simulations including pedestrian counter flow with preference (Case A), with conflicting preference (Case B), and without preference (Basic case) were performed. Results show that the presented model can capture some essential features of pedestrian counter flow with various walking preference. It is not always necessary to intervene the behavior of pedestrians ’ conflicting preference, since appropriate degree of preference is sometimes beneficial to movement of pedestrians. In addition, with the significant influence of position exchange, the flow in Case A with more orderly motion is more efficient in the context of low density, while the flow in Case B with more frequent interactions is more efficient in the case of high density. The findings in this study will be helpful in crowd management as well as the design and operation of pedestrian facilities.

Electric Spring for Voltage and Power Stability and Power Factor Correction

electric powered Animation (ES), another smart applique innovation, has advanced been accustomed for accessories voltage and expertise adherence ina accursedly managed/unbiased sustainable interest the front fueled network. it's been proposed as a vicinity adornment business agency deal with to board voltage and adroitness guiding precept. on this cardboard ,each different little bit of leeway amendment is displayed for the engaging in of the electric spring, in amalgamation with non-primary architectonics amaranthine like electric heaters, refrigerators and hub cooling framework. This favorable position exchange should probably board talent place of job adjustment of the framework, voltage backing, and capacity direct contrary for the expository burdens, for instance, the form's advertising framework, in boom to the entire attributes of electrical motion of voltage and adroitness energy. The proposed desired characteristic alteration is contrasted and antiquated ES's little bit of leeway amendment expansiveness surrendered receptive electricity is infused. The ad libbed benefit trade opens new roads for the contraption of the electrical activity to a greater noteworthy admeasurement via accessories voltage and adroitness adherence and quality the capacity unmatched in the inexhaustible interest managed small scale frameworks.

Accurate position exchange of stamen and stigma by movement in opposite direction resolves the herkogamy dilemma in a protandrous plant, Ajuga decumbens (Labiatae)

Herkogamy is an effective way to reduce sexual interference. However, the separation of stigma and anther potentially leads to a conflict because the pollen may be placed in a location on the pollinator different from the point of stigma contact, which can reduce pollination accuracy. Floral mechanisms aiming to resolve this conflict have seldom been explored. The floral biology of protandrous Ajuga decumbens was studied to uncover how the herkogamy dilemma can be resolved. Flower anthesis was divided into male, middle, female and wilting phases. The positions of stigma and stamen were dissimilar in different flower development stages. We measured the distance of the stamen and stigma to the lower corolla lip at different floral phases, which was the pollinators’ approaching way. The pollen viability, stigma receptivity, pollen removal and pollen deposition on stigma were investigated at different phases. During the male phase, the dehisced anthers were lower than the stigma, located at the pollinators’ approaching way, and dispersed most pollen with high viability. As the flower developed, the anthers moved upwards, making way for pollen deposition during the female phase. Meanwhile, the stigma becomes receptive by moving into the way and consequently was deposited with sufficient pollen. The position exchange of the stamen and stigma created a dynamic herkogamy at the floral phase with different sexual functions. This floral mechanism effectively avoided sexual interference and maintained pollination accuracy. In Ajuga, the movement herkogamy might be of adaptive significance in response to the changes in the pollination environment.

Pengaruh Alih Baring Selama Fototerapi Terhadap Perubahan Kadar Bilirubin Pada Ikterus Neonatorum di Ruang HCU Neonatus RSUD Dr. Moewardi

Abstrack: Position Exchange Is Right Oblique, Supine, Left Oblique, And Prone In Phototherapy. Icterus neonatorum is neonatus condition with high bilirubine levels. Objective to determine the effect position exchange in phototherapy to the bilirubine levels in icterus neonatorum in HCU Neonatus Dr. Moewardi General Hospital. Researchers used a quasy experimental design pre- post test one group. Researcher used a sample of 25 neonatus. Analysis of differences in pre and post bilirubine levels of phototherapy. The collected data was analyzed by using paired t test. Retrieved from 25 respondents, it is the majority age of icterus neonatorum is 4 days (28,6%) and the majority of the male gender with a percentage of 52 %. Research results obtained that effect position exchange in phototeraphy to the bilirubine levels in icterus neonatorum in HCU Neonatus Dr. Moewardi General Hospital with p =0.00. Based on the analysis it can be concluded that there is a significant the effect between position exchange in phototherapy to the bilirubine level in icterus neonatorum in HCU Neonatus Dr. Moewardi General Hospital.
