Quantum Phase Transition from a Spin-liquid State to a Spin-glass State in the Quasi-1D Spin-1 System Sr1-xCaxNi2V2O8

We report a quantum phase transition from a spin-liquid state to a spin-glass state in the quasi-one dimensional (1D) spin-1 system Sr1-xCaxNi2V2O8, induced by a small amount of Ca-substitution at Sr site. The ground state of the parent compound (x = 0) is found to be a spin-liquid type with a finite energy gap of 26.6 K between singlet ground state and triplet excited state. Both dc-magnetization and ac-susceptibility studies on the highest Ca-substituted compound (x = 0.05) indicate a spin-glass type magnetic ground state. With increasing Ca-concentration, the spin-glass ordering temperature increases from 4.5 K (for the x = 0.015 compound) to 6.25 K (for the x = 0.05 compound). The observed results are discussed in the light of the earlier experimental reports and the theoretical predictions for a quasi-1D spin-1 system.Comment: 26 pages, 8 figures, 3 table

Experimental study of paraffin wax potential as a physical modelling material for local environment

An experimental study on paraffin wax was done to investigate its potential as modelling material and observing the effect of local environment thermal parameter. Testing and analysis done using cromatographer, differential calorimeter scanner, instron strength analyzer, durometer and laboratory experimental equipment have given us the opportunity to clarify certain elements in understanding the wax characteristics. Wax, through this experiment, have been proven viable as a modelling material. The surface finish is found to be better than Industrial Design (ID) clay and stable for the local environment as long as it is not exposed to direct heat source such as sunlight

Two-dimensional Induced Ferromagnetism

Magnetic properties of materials confined to nanometer length scales are providing important information regarding low dimensional physics. Using gadolinium based Langmuir-Blodgett films, we demonstrate that two-dimensional ferromagnetic order can be induced by applying magnetic field along the in-plane (perpendicular to growth) direction. Field dependent exchange coupling is evident in the in-plane magnetization data that exhibit absence of hysteresis loop and show reduction in field required to obtain saturation in measured moment with decreasing temperature.Comment: 4 pages, 3 postscript figures, corrected paper forma

Eksekusi terhadap Pidana Tambahan Berupa Uang Pengganti pada Tindak Pidana Korupsi oleh Kejaksaan Negeri Padang (Studi Putusan Nomor: 19/pid.sus-tpk/2015/pn Pdg)

Broadly speaking, the execution is one of the jurisdiction of the prosecutor as regulated by the law to enforce the judge's decision, as well as the additional criminal under Article 10 point (b) of the Criminal Code and Article 18 Paragraph (1) of Law Number 31 Year 1999 regarding Eradication of Corruption. In fact it is undeniable that corruption is currently one of the extraordinary crimes that have an impact on the state's financial losses, which are of the essence in returning the state's losses, particularly with regard to the execution of additional crimes in the form of substitute payments on corruption. The problems in this thesis are: Firstly, how is the execution process of additional criminal in the form of replacement money on corruption crime by Padang State Attorney ?. Secondly, what are the obstacles encountered by the Padang District Attorney in the execution of additional crime in the form of substitute money on corruption and how is the effort to overcome these obstacles?. Specification of this research is an analytical descriptive research. Approach method used is normative juridical as main approach and supported by empirical juridical approach. The data used are secondary data and primary data. The data obtained were analyzed qualitatively and presented analytically descriptively. Based on the research and discussion it can be seen that: First, the process of execution of additional crime in the form of replacement money on corruption crime by State Prosecutor of Padang is done through execution of court decision which has obtained legal force still done by prosecutor, after the clerk sends a copy of decision letter to him, this requires that a new execution be exercised by the prosecutor, after the clerk has sent a copy of the verdict to him, so the defendant refuses to be executed on the basis of the quotation of the permanent verdict in addition to the court's verdict giving no legal basis on the property of the accused that has been confiscated. This is based on the task of the Prosecutor as the executor to execute in accordance with existing legislation. Second, the obstacles encountered by the Padang District Attorney in additional criminal execution in the form of substitute money in corruption are the absence of a standard rule governing the execution mechanism, including guidance if the defendant is unable to pay for all or part of the additional penalty imposed. The easy access to double identity card making it difficult to trace the convicted property, the duration of the judicial process until the verdict has the legal power to keep the execution and the number of convicts who prefer to go through the additional criminal sanction of the additional criminal. While the efforts made by the State Prosecutor Padang is to reform the legislation related to the authority of the Public Prosecutor Office through the Attorney General to seize the assets of someone suspected of having committed a criminal act of corruption that harm the state finances

Long-range and short-range magnetic correlations, and microscopic origin of net magnetization in the spin-1 trimer chain compound CaNi3P4O14

Spin-spin correlations and microscopic origin of net magnetization in the spin-1 trimer chain compound CaNi3P4O14 have been investigated by powder neutron diffraction. The present study reveals a 3D long-range magnetic ordering below 16 K where the magnetic structure consists of ferromagnetic trimers that are coupled ferromagnetically along the spin-chain. The moment components along the a and c axes arrange antiferromagnetically. Our study establishes that the uncompensated moment components along the b axis result in a net magnetization per unit cell. The magnetic structure, determined in the present study, is in agreement with the results of recent first principles calculation; however, it is in contrast to a fascinating experimental prediction of ferrimagnetic ordering based on the periodicity of the exchange interactions in CaNi3P4O14. Our study also confirms the presence of broad diffuse magnetic scattering, due to 1D short-range spin-spin correlations, over a wide temperature range below ~50 K down to a temperature well below the Tc. Total neutron scattering analysis by the RMC method reveals that the dominating spin-spin correlation above Tc is ferromagnetic and along the b axis. The nearest neighbour spin-spin correlations along the a and c axes are found to be weakly antiferromagnetic. The nature of the trimer spin structure of the short-range state is similar to that of the 3D long-range ordered state. The present investigation of microscopic nature of the magnetic ground state also explains the condition required for the 1/3 magnetization plateau to be observed in the trimer spin-chains. In spite of the S=1 trimer chain system, the present compound CaNi3P4O14 is found to be a good realization of 3D magnet below the Tc=16 K with full ordered moment values of ~2 mu_B/Ni2+ (1.98 and 1.96 mu_B/Ni2+ for two Ni sites, respectively) at 1.5 K.Comment: 10 pages, 8 figure

Bias Gender dalam Kewarisan Menurut Ulama Bugis

Continous dialogue between textualist and contextualist about formula of inheritance where textualist refers to universality of texts and contextualist base on particular background. Most contextualists try to consider various external of texts to find core values that is justice. Formula 2 : 1, that is, “man gets two pieces of inheretances and woman gets one piece inheretance†(malempa’ orowanewe majjujung makkunraiye) covers right and responsibility of son to his doughter. Number 2 is maximum of son’s rigth and number 1 is minimum of daughters right. This inheritance division is implemented within the Bugis culture and yet it is elastically applied. Therefore, it implies that the core value of the texts are conisedred deeper than the texts themselves. Most Bugis scholars understand that 2 : 1 as the true meaning of texts. It is a logical consequence of influence of literatures besides common method and analytical method where mostly cannot formulate concept of inheritance comprehensively
