The time it takes: Temporalities of planning

State planning has been a defining means for modern subjects to regulate the passage of time. In practice, it is the focus of multiple conflicts and doubts, which planners attempt to mediate. In this paper, I address the regimes of time that planning both promotes and encounters, and tease out what these imply for anthropology. Using ethnography of Norwegian and Swedish planning offices and their encounters with participatory planning, I question recent claims that there has been an evacuation of the near future or a retreat of administrative intervention. I also suggest that recent anthropological concerns with time have been confined by their attempts to characterize the changing timescapes of specific modal shifts, such as from the modern to the neoliberal. Instead, in my ethnography, I focus not on tracking epochal breaks in time, but on demonstrating how time is manipulated, and how multiple temporalities are performed in ongoing projects of democratic planning

The role of grain dynamics in determining the onset of sediment transport

Sediment transport occurs when the nondimensional fluid shear stress $\Theta$ at the bed surface exceeds a minimum value $\Theta_c$. A large collection of data, known as the Shields curve, shows that $\Theta_c$ is primarily a function of the shear Reynolds number ${\rm{Re}}_*$. It is commonly assumed that $\Theta>\Theta_c({\rm{Re}}_*)$ occurs when the ${\rm Re}_*$-dependent fluid forces are too large to maintain static equilibrium for a typical surface grain. A complimentary approach, which remains relatively unexplored, is to identify $\Theta_c({\rm{Re}}_*)$ as the applied shear stress at which grains cannot stop moving. With respect to grain dynamics, ${\rm{Re}}_*$ can be viewed as the viscous time scale for a grain to equilibrate to the fluid flow divided by the typical time for the fluid force to accelerate a grain over the characteristic bed roughness. We performed simulations of granular beds sheared by a model fluid, varying only these two time scales. We find that the critical Shields number $\Theta_c({\rm Re}_*)$ obtained from the model mimics the Shields curve and is insensitive to the grain properties, the model fluid flow, and the form of the drag law. Quantitative discrepancies between the model results and the Shields curve are consistent with previous calculations of lift forces at varying ${\rm Re}_*$. Grains at low ${\rm Re}_*$ find more stable configurations than those at high ${\rm{Re}}_*$ due to differences in the grain reorganization dynamics. Thus, instead of focusing on mechanical equilibrium of a typical grain at the bed surface, $\Theta_c({\rm{Re}}_*)$ may be better described by the stress at which mobile grains cannot find a stable configuration and stop moving.Comment: to appear in Phys.

Determining the Onset of Hydrodynamic Erosion in Turbulent Flow

We revisit the longstanding question of the onset of sediment transport driven by a turbulent fluid flow via laboratory measurements. We use particle tracking velocimetry to quantify the fluid flow as well as the motion of individual grains. As we increase the flow speed above the transition to sediment transport, we observe that an increasing fraction of grains are transported downstream, although the average downstream velocity of the transported grains remains roughly constant. However, we find that the fraction of mobilized grains does not vanish sharply at a critical flow rate. Additionally, the distribution of the fluctuating velocities of non-transported grains becomes broader with heavier tails, meaning that unambiguously separating mobile and static grains is not possible. As an alternative approach, we quantify the statistics of grain velocities by using a mixture model consisting of two forms for the grain velocities: a decaying-exponential tail, which represents grains transported downstream, and a peaked distribution centered at zero velocity, which represents grains that fluctuate due to the turbulent flow but remain in place. Our results suggest that more sophisticated statistical measures may be required to quantify grain motion near the onset of sediment transport, particularly in the presence of turbulence.Comment: 9 pages, 7 figure

Lepton Flavor Violation at the Large Hadron Collider

We investigate a potential of discovering lepton flavor violation (LFV) at the Large Hadron Collider. A sizeable LFV in low energy supersymmetry can be induced by massive right-handed neutrinos, which can explain neutrino oscillations via the seesaw mechanism. We investigate a scenario where the distribution of an invariant mass of two hadronically decaying taus (\tauh\tauh) from \schizero{2} decays is the same in events with or without LFV. We first develop a transfer function using this ditau mass distribution to model the shape of the non-LFV \tauh\mu invariant mass. We then show the feasibility of extracting the LFV \tauh\mu signal. The proposed technique can also be applied for a LFV \tauh e search.Comment: 8 pages, 6 figures, accepted for publiucation in PR

Faktor-faktor Yang Mempengaruhi Obesitas Pada Anak Tk Providensia Manado

:Obesity is starting to become a worldwide health problem, according to WHO obesity is a global epidemic and become a health problem that must be addressed. Factors affecting nutrition are, among others, eating habits and physical activity. The research goal is to determine the factors - factors that influence obesity in children in kindergarten providence Manado. This type of research is an observational study with cross sectional design to examine the relationship between risk factors with the result that occurred in the form of obesity at the same time. Results There were 8 people obese category I have a habit of eating low (26.6%), obesity II category there are 20 people who have a habit of eating high (66.7%). Statistical analysis showed p-value = 0.00 or p <0.05. It can be concluded there is a significant relationship between eating habits of respondents with obesity. There are 8 categories of obesity I have moderate activity category (26.6%), class II obesity have lower levels of physical activity that is 13 people (43.3%). Statistical analysis showed that the statistical test p-value = 0.04 or p = <0.05. It can be concluded there is a significant relationship between physical activity respondents with Obesity

.Health education is a process to connects the gap of health information and health practices, which motivates a person to obtain information and be able to keep themselves become healthier by avoiding bad habits.Modeling is a person's ability to improve attention, retention, reproduction and motivation during the learning process.Knowledge of mothers on infant growth stimulation on 0-6 months can reduce errors and improve care for mothers in positive growth. Ignorance of mother about the infant growth stimulation on 0-6 months can impact on maternal difficulty to understand the importance of stimulating growth and development of infants on 0-6 months. The purpose of this Research was to determine the influence of health education with mother's modeling approach to knowledge in stimulating the growth and development of infants at 0-6 months. This Research methods uses a pre-experimental design using the design of one group pre-post test. Sampling technique is purposive sampling with a sample size of 99 people, using Wilcoxon test, at the significance level of 95% (á 0.05). Results of statistical test p value = 0.000 á <0.05. Conclusion of this research are significant health education approach to knowledge modeling mother in stimulating the growth and development of infants at 0-6 months in Integrated Service Post in The Working Area at Tomalou Public Health Center of Tidore Islans. Advice the importance of health education with modeling approaches to mothers about infant growth stimulation on 0-6 months in order to be applied at home
