The method that I use in this study is the experimental method, that is by giving the treatment at two different sample classes. Based on the research results of the final test can be concluded there is an increase in the ability of students to solve problems that get better Treffinger models compared with the students who get a conventional model
On determination of the geometric cosmological constant from the OPERA experiment of superluminal neutrinos
The recent OPERA experiment of superluminal neutrinos has deep consequences
in cosmology. In cosmology a fundamental constant is the cosmological constant.
From observations one can estimate the effective cosmological constant
which is the sum of the quantum zero point energy
and the geometric cosmological constant . The
OPERA experiment can be applied to determine the geometric cosmological
constant . It is the first time to distinguish the contributions of
and from each other by experiment. The
determination is based on an explanation of the OPERA experiment in the
framework of Special Relativity with de Sitter space-time symmetry.Comment: 7 pages, no figure
Effect of Methanol Induction and Incubation TIME on Expression of Human Erythropoietin in Methylotropic Yeast Pichia Pastoris
Erythropoietin (EPO) is a glycoprotein hormone consists of 165 amino acids and has molecular mass of 30,400 Daltons. The large quantities of these hormone required to satisfy clinical demand are currently met by recombinant expression in mammalian cell, namely chinese hamster ovary (CHO). Pichia pastoris has become popular yeast based protein production systems to substitute mammalian expression systems. P. pastoris is capable to use methanol as sole carbon and energy source. In this study, recombinant human EPO (rhEPO) protein obtained by expressing the hEPO gene in methylotropic yeast P. pastoris, strain X33. The present work was carried out to study the optimal methanol concentration for induction and the incubation time to obtain rhEPO protein. To perform this study, the transformed P. pastoris was induced with various concentrations of methanol (0%, 0.5%, 1%, 2.5%, 5%, 10%, and 20%) and incubation times (0 hours, 24 hours, 48 hours, 72 hours, 96 hours, 120 hours, and 144 hours). The results demonstrate that the highest protein expression level occurred at concentration of 2.5% methanol induction, while the optimal incubation time was at 48 hrs
Pengaruh Pemeriksaan Pajak terhadap Kepatuhan Wajib Pajak dan Dampaknya terhadap Efektivitas Penerimaan Pajak Penghasilan Badan
Human resources are a supporting factor for companies to survive in competition. Compensation plays an important role in improving employee performance, one of the main reasons a person works is to make ends meet. Someone will work maximally to get the compensation in accordance with expectations. The compensation policy in addition to rewarding employees for the work performed by employees is also one way to retain potential employees.
Based on the variables studied, the research method used in this research is descriptive and associative method. Descriptive research is a study conducted to determine the value of independent variables and does not make the comparison of variables with other variables Descriptive research here aims to obtain a picture of direct compensation, indirect compensation and employee performance at PT Pranata Jaya Abadi. While the method of associative research is research that aims to determine the influence or also the relationship between two variables or more.
The results of this study show a multiple linear regression equation as follows: Y = 0.414 + 0.997X1 + 0.866X2, which can be interpreted as that the variables X1 and X2 are zero (0), then the variable Y will be worth 0.414 units; if the direct compensation (X1) increases by one unit and the other variable is constant, then the Y variable will increase by 0.997 units, and if the indirect compensation (X2) increases by one unit and the other variable is constant, then the Y variable will increase by 0.866 units.
The conclusion of this study obtained the value of determination coefficient of 82.7% or the value of 0.827 which indicates the meaning that direct compensation (X1) and indirect compensation (X2) gives simultaneous effect of 82.7% on employee performance (Y ). While the rest of 17.3% influenced by other factors that ignored the author. The value of Adjusted R2 0.820 or the value of 82.0% indicating the meaning that, if there are other independent variables to be included, direct and indirect compensation variables, remain to have an effect of 82.0%.

Tripartite three mode Gaussian state undergoes parametric amplification and
amplitude damping as well as thermal noise is studied. In the case of a state
totally symmetrically interacting with the environment, the time dependent
correlation matrix of the state in evolution is given. The conditions for fully
separability and fully entanglement of the final tripartite three mode Gaussian
state are worked out.Comment: 9 pages, 3 figure
Front-end multi-channel PMT-associated readout chip for hodoscope application
International audienceThe system development requires a dedicated multi-channel readout ASIC (Application Specific Integrated Circuit) to be associated with the MaPMTs. Each channel should have very low input impedance to avoid electrical crosstalk between adjacent channels and to minimize effects of detector and wiring capacitances (Cd + Cw). Crosstalk between channels may degrade position resolution, while these capacitances may degrade both frequency and noise performances. Each channel should also provide two separated outputs corresponding respectively to high-speed signal-event detection and low-noise signal-charge quantification at low counting rate. This paper presents a readout chip for this purpose. It has been designed in a 0.35µm SiGe BiCMOS process (AMS). This process allows the use of RF and large-transconductance bipolar components, which is useful for the design of wide-band, low-impedance and low-noise circuits with improved performances

10 x 112Gb/s PDM-QPSK transmission over 5032 km in few-mode fibers
Few-mode fibers (FMFs) are used for the first time to transmit over 5000 km. Ten WDM channels with 50GHz channel spacing at 112 Gb/s per channel using PDM-QPSK are launched into the fundamental mode of the FMFs by splicing single-mode fibers directly to the FMFs. Even though few-mode fibers can support an additional spatial mode LP11 at 1550 nm, the signal remains in the fundamental mode and does not experience mode coupling throughout fiber transmission. After each span the signal is collected by a second single-mode fiber which is also spliced to the FMF. Span loss is compensated by single-mode EDFAs before it is launched to the next FMF span. The lack of mode coupling ensures that the signal does not suffer any impairments that may result from differential mode delay or excess loss. Therefore the FMFs used in this single-mode operation have the same bandwidth as single-mode fibers. Experimental results verified that FMFs have the significant advantage of large core size which reduces the nonlinear impairments suffered by the signal. It is shown that FMFs with an effective area of 130 mu m(2), have an optimum launch power 2 dB higher compared to standard single-mode fibers and as a result a 1.1 dB improvement in the Q-factor is obtained after 3000 km
