It is noted that local wisdom is considered as an adjustable thing, flexible so that in variously social element openly to discuss it out. The main topics to discuss is to correlate local wisdom phenomenon and also found a social dilemma might arise there, such as communal activities recorded public see allergic with any old values, having proudly with newly values, it is all viewed from social anthropology perspective. This research has been done in qualitative approach within a very long time duration period calculated in completing Doctoral program in study, still to do re-study ( another research ) only done them in a short time, it has already data previously reasonable, in this case to community of Ocu on Kabupaten Kampar Riau. Accordingly, a partly of the study is categorized as ethnography research due to the source of data originally from informants chosen purposively under consideration of appropriately quality, figurative value, or someone as considered someone with much knowledge about the topic is discussing to. This study has found own very high strategic values which things can be set as instrument for criticizing even in this case with own initiative to commence re-repairmen particularly to its cultural values holed by local people whose neglect own old cultural values available, unfortunately in highly obsession to receive newly cultural values at any time having not comfortable however with the living pattern and their character in daily life, thence emerging in what generally called lost cultural with local condition is well known with  “aghokkan ujan dilangik, ayu dikulam babuangkan”.

Rupture Behavior

Available equipment initially developed for welding research studies was used to investigate the creep-rupture behavior of AISI type 347 stainless steel in a very-high-temperature range from 62 to 86 percent of the solidus. Stress applications from 900 to 28,000 psi gave rupture times from a fraction of a second to several hundred seconds with thousandfold variations of minimum creep rate. Results could be presented by conventional means. Data scatter on a Monkman-Grant plot was typical. Correlation and extrapolation procedures developed by Larson-Miller, Manson-Haferd, Dorn, Korchynsky, and Conrad for conventional long-time results were found to be applicable, with preference being given to the Manson-Haferd procedures.

New View

The writing of this journal aims to give a new view of how a woman who in Ono Niha mythology has very high respect, but in reality the woman in Nias is the object of injustice in the culture of Patriarchy that has been formed for a long time in Nias. In this journal, using a descriptive-analytical approach with a qualitative approach. The qualitative approach emphasizes the accuracy of data, it will use an inductive approach, which means that data will be collected, approached, and abstracted through interviews, literature and field observations. Thus the authors obtain data that in Nias, women experienced oppression in a real patriarchal culture because of the social construction that made it number two and regarded as weak and low based on the nature of the natural label. The oppression experienced by women in society socially, politically and religiously. The basis of the injustice in society in various fields is rooted in the culture of patriarchy where men assume that women belong to their property, servants and complementaries.

This chapter presents the application of LBE to flows at moderate Reynolds numbers, typically hundreds to thousands. This is an important area of theoretical and applied fluid mechanics, one that relates, for instance, to the onset of nonlinear instabilities and their effects on the transport properties of the unsteady flow configuration. The regime of Reynolds numbers at which these instabilities take place is usually not very high, of the order of thousands, hence basically within reach of present day computer capabilities. Nonetheless, following the full evolution of these transitional flows requires very long-time integrations with short time-steps, which command substantial computational power. Therefore, efficient numerical methods are in great demand. Also of major interest are steady-state or pulsatile flows at moderate Reynolds numbers in complex geometries, such as they occur, for instance, in hemodynamic applications. The application of LBE to such flows will also briefly be mentioned

And Diffusion

A mathematical model of river hydrodynamics with cascade reservoirs and pollutant has been established and verified by using analytic solutions of partial differential equation for transportation and diffusion. Ten dispatch schedules of single or multi- reservoirs have been set up and executed according to that a pollution accident occurred upstream or downstream to a reservoir. It shows that which dispatch schedule should be selected was decided by sensitive factors of a target river segment downstream. A dispatch model of large flux with short time duration by utilizing a reservoir nearest to the segment was more appropriate for which was more sensitive to concentration than other factors, while a model of appropriate flux discharge with long time duration was more suitable for those being more sensitive to extra concentration retention of pollutants. Compared with a single reservoir dispatch, multi-reservoirs have larger effective storage capacity to reduce the loss by a sudden water pollution accident better by supplement water step by step from upstream to downstream.

Impact Problem

Impact wrench is a popular hand tool whose mechanism is featured with impact characterized by short time duration and large contact torque. The nonlinear impact problem has drawn researchers’ interests for a long time and the investigation is still undergoing. Fully and accurately modeling impact can facilitate the understanding and improving the performance of impact wrench. Under certain circumstance, not only coefficient of restitution is interested but also the whole impact process. Hence, discrete impact model cannot fulfil these requirements and dynamic modeling is indispensable. At the same time, sufficient knowledge about contact parameters such as contact stiffness is necessary for accurately impact modeling. But these parameters are usually not readily available. Moreover, researchers mainly focused on translational impact problem while rotational impact problem is ignored. In this paper, Hunt-Crossley nonlinear contact model is applied and extended in torsional impact dynamic modeling. Based on this model, an experimental method is developed to evaluate the distribution of inertias in lumped parameter models. Contact stiffness is measured based on spectrum results. To obtain reliable experimental data, impact wrench is driven by a servo motor to generate a controllable torque impulse. Contact stiffness is acquired under different impact speed. Results show the nonlinear relationship between contact stiffness and impact speed.

AbstractAn accelerated micro-foil is used to ignite a pre-compressed cylindrical shell containing deuterium–tritium fuel. The well-known shock wave ignition criterion and a novel criterion based on heat wave ignition are developed in this work. It is shown that for heat ignition very high impact velocities are required. It is suggested that a multi-petawatt laser can accelerate a micro-foil to relativistic velocities in a very short time duration (˜picosecond) of the laser pulse. The cylindrical geometry suggested here for the fast ignition approach has the advantage of geometrically separating the nanosecond lasers that compress the target from the picosecond laser that accelerates the foil. The present model suggests that nuclear fusion by micro-foil impact ignition could be attained with currently existing technology.

Background: Although DC Bead has been useful in treatment of multiple and large hepatocellular carcinoma, loading time of doxorubicin into the DC Bead takes a long time of 30-120 minutes. Epirubicin is also used as an antitumor agent together with DC Bead, but its loading efficiency was not sufficiently elucidated. Methods: To shorten loading time of epirubicin into DC Bead (100-300µm, 300-500µm, 500-700µm), we examined the following three methods after mixing the drug: (a) let stand in room temperature, (b) agitated for 30 seconds with Vortex mixer, and (c) sonicated for 30 seconds with ultrasonic cleaner. After loading of epirubicin by each method, supernatant concentration for epirubicin was assayed at 5, 10, 30, 60, and 120 minutes. Results: Epirubicin loading rates for small bead (100-300µm) at 5 minutes were 82.9 % in group a, 93.8% in group b, and 79.9 % in group c. Similarly, medium bead (300-500µm), 40.1% in group a, 65.7% in group b and 45.5% in group c, respectively. In large-sized bead (500-700µm), loaded rates of epirubicin were 38.8% in group a, 59.0% in group b and 48.0% in group c. Agitation of mixture of epirubicin and DC Bead with Vortex mixer significantly shortened the loading time, but sonication did not affect the time required. Microscopic examination did not lead to any morphological change of microspheres in all the methods. Conclusions: Short time of agitation with Vortex mixer reduced the necessary time for loading of epirubicin in every standard of DC Bead.
