In essence, the learning process subjects Citizenship Education can be performed with various models and techniques. Models and techniques of learning works to facilitate students learning the material presented by the teacher, so as to increase student competence that ultimately increase learning outcomes. The research objective of this class action is to enhance the learning process and improve learning outcomes of students at SMK Negeri 2 Purbalingga through Two techniques stay two stray. Formulation of the problem in this study is "How the quality of the learning process of Citizenship Education at SMK N 2 Purbalingga years 2010-2011. This research was conducted by research design class action through 3 cycles and ach cycle conducted 2 meetings. Each cycle consists of four measures, planning, implementation, observation and reflection. Source of research data include primary data and secondary data. Measure of the success of class actions is an increase in learning outcomes so completely100%. The data analyzed are the results of the evaluation data(test results of student learning) and non-test of observational data from the observer. The results showed that two stray stay Two techniques to improve student learning outcomes proved the value of the average pre-cycle 48, cycle 1 score of 64, seklus 2 score 3 score of 68 and 72 cycles. Also increase the activity of the learning process that teachers do. Based on the observation sheet that has been filled by the observers obtained results of teacher activity score of7.7 in cycle 1, cycle 2 score of 8.33 and at the end of cycle 3score of 9.16. Likewise, students in the learning activities also increased. Initial cycle of a student activity reached 68.9, a 72.8cycle 2 and cycle 3 to 77.6. For group activities increased from a score of 81 in cycle 1, to 84 in cycle 2 and cycle 3 becomes. 86. Improved student learning outcomes from the initial conditionsexhaustiveness cycle 1 to 47.36% to 64%, 86% cycle 2 and cycle3 to complete 100%

Efektivitas Daun Murbei Sebagai Pengganti Konsentrat Dalam Sistem Rumen in Vitro

Mulberry leave has a great potential as animal feed because of its high nutrient content. It also has deoxynojirimycin (DNJ) compound, that is potential to increase fermentability of fibrous feed in ruminal system. An in vitro experiment was conducted to investigate the capability of mulberry leaves to substitute concentrate as feed for ruminant in increasing fermentability of fibrous feed in ruminal system. This experiment was carried out using randomized block design with five treatments and four replications. The treatments were: P0 (50% rice straw + 50% concentrate) as a control, P1 (50% rice straw + 37.5% concentrate + 12.5% mulberry leave), P2 (50% rice straw + 25% concentrate + 25% mulberry leave), P3 (50% rice straw + 12.5% concentrate + 37.5% mulberry leave), P4 (50% rice straw + 50% mulberry leave). Variables measured were fermentability (NH3 and VFA concentrations), pH, gas production, dry matter and organic matter digestibility. Data were analyzed using analysis of variance and duncan multiple range test was further used to test the significant differences. VFA concentration, dry matter digestibility and organic matter digestibility were significantly difference (P < 0.05) among treatments. However, there was no significant effect on the other variables. It is concluded that mulberry leave are able to substitute the concentrate and increased fermentability of fibrous feed in ruminal system

Quantum Transparency of Anderson Insulator Junctions: Statistics of Transmission Eigenvalues, Shot Noise, and Proximity Conductance

We investigate quantum transport through strongly disordered barriers, made of a material with exceptionally high resistivity that behaves as an Anderson insulator or a ``bad metal'' in the bulk, by analyzing the distribution of Landauer transmission eigenvalues for a junction where such barrier is attached to two clean metallic leads. We find that scaling of the transmission eigenvalue distribution with the junction thickness (starting from the single interface limit) always predicts a non-zero probability to find high transmission channels even in relatively thick barriers. Using this distribution, we compute the zero frequency shot noise power (as well as its sample-to-sample fluctuations) and demonstrate how it provides a single number characterization of non-trivial transmission properties of different types of disordered barriers. The appearance of open conducting channels, whose transmission eigenvalue is close to one, and corresponding violent mesoscopic fluctuations of transport quantities explain at least some of the peculiar zero-bias anomalies in the Anderson-insulator/superconductor junctions observed in recent experiments [Phys. Rev. B {\bf 61}, 13037 (2000)]. Our findings are also relevant for the understanding of the role of defects that can undermine quality of thin tunnel barriers made of conventional band-insulators.Comment: 9 pages, 8 color EPS figures; one additional figure on mesoscopic fluctuations of Fano facto

A parametric study of textile artificial magnetic conductor with wire dipole at 2.45GHZ and 5.8GHZ

Textile Artificial Magnetic Conductor (AMC) with wire dipole is presented. The AMCs are made of fleece and Shieldit fabrics and were designed to have in-phase reflections at 2.45GHz and 5.8GHz. Thorough parametric studies based on AMC unit cell have been performed to obtain the optimized design. Performance comparison between different types of environments, fabrics and arrays size were also conducted. The proposed AMC and wire dipole are designed, simulated, fabricated and tested. Results of return loss, radiation pattern and gain are presented. Results show that forward directive radiation pattern with improved gain are achieved with the introduction of the AMC at both 2.45GHz and 5.8GHz. The proposed textile AMC is suitable for body centric communication systems

Details of the 4m RSE interferometer control method as well as the design of the experimental setup will be presented

Quantum-secured blockchain

Blockchain is a distributed database which is cryptographically protected against malicious modifications. While promising for a wide range of applications, current blockchain platforms rely on digital signatures, which are vulnerable to attacks by means of quantum computers. The same, albeit to a lesser extent, applies to cryptographic hash functions that are used in preparing new blocks, so parties with access to quantum computation would have unfair advantage in procuring mining rewards. Here we propose a possible solution to the quantum era blockchain challenge and report an experimental realization of a quantum-safe blockchain platform that utilizes quantum key distribution across an urban fiber network for information-theoretically secure authentication. These results address important questions about realizability and scalability of quantum-safe blockchains for commercial and governmental applications.Comment: 7 pages, 2 figures; published versio

Static Solitons of the Sine-Gordon Equation and Equilibrium Vortex Structure in Josephson Junctions

The problem of vortex structure in a single Josephson junction in an external magnetic field, in the absence of transport currents, is reconsidered from a new mathematical point of view. In particular, we derive a complete set of exact analytical solutions representing all the stationary points (minima and saddle-points) of the relevant Gibbs free-energy functional. The type of these solutions is determined by explicit evaluation of the second variation of the Gibbs free-energy functional. The stable (physical) solutions minimizing the Gibbs free-energy functional form an infinite set and are labelled by a topological number Nv=0,1,2,... Mathematically, they can be interpreted as nontrivial ''vacuum'' (Nv=0) and static topological solitons (Nv=1,2,...) of the sine-Gordon equation for the phase difference in a finite spatial interval: solutions of this kind were not considered in previous literature. Physically, they represent the Meissner state (Nv=0) and Josephson vortices (Nv=1,2,...). Major properties of the new physical solutions are thoroughly discussed. An exact, closed-form analytical expression for the Gibbs free energy is derived and analyzed numerically. Unstable (saddle-point) solutions are also classified and discussed.Comment: 17 pages, 4 Postscript figure
